Systems and methods for identifying points of interest in pipes or drain lines
Systems and methods for identifying one or more points of interest in pipes or drain lines are described. Examples of points of interest include blockages caused by debris in the pipe or drain line. The systems are incorporated into drain cleaning machines. Also described are drain cleaning machines utilizing the systems.
1. A drain cleaner comprising:
a drain cleaning cable;
a rotatable drum, the drum storing at least a portion of the cable;
a motor for rotating the drum;
a counter configured to determine a length of the cable dispensed from the drain cleaner;
a current sensor configured to determine electrical current draw of the motor; and
a controller configured to determine occurrence of a distal end of the cable encountering a point of interest in an enclosed region based on data received from the current sensor;
wherein the controller includes communication provisions for communicating to a mobile device, the controller communicating at least one point of interest and the linear amount of the cable dispensed from the drain cleaner;
wherein the mobile device is configured to generate graphical illustrations representative of the enclosed region including the at least one point of interest with respect to the linear amount of the cable dispensed from the drain cleaner.
2. The drain cleaner of claim 1 , wherein the counter includes at least one sensor assembly including a first pickup associated with the drum and a first sensor affixed to a stationary component of the drain cleaner and in operable communication with the first pickup.
3. The drain cleaner of claim 2 , wherein the drain cleaner further comprises a cable follower, and the counter includes a second sensor assembly including a second pickup associated with the cable follower and a second sensor affixed to a stationary component of the drain cleaner and in operable communication with the second pickup.
4. The drain cleaner of claim 1 , wherein the controller includes communication provisions for communicating to a mobile device, the controller communicating data from the current sensor and the linear amount of the cable dispensed from the drain cleaner.
5. The drain cleaner of claim 4 , wherein the mobile device is configured to generate graphical illustrations representative of the enclosed region including the current sensor data with respect to the linear amount of the cable dispensed from the drain cleaner.
6. The drain cleaner of claim 4 wherein the communication provisions provide wireless communication with the mobile device.
7. The drain cleaner of claim 1 wherein the motor is a brushless DC (BLDC) motor.
8. A drain cleaner comprising:
a drum;
a motor for rotating a cable, the cable at least partially housed in the drum;
a counter configured to determine a length of the cable dispensed from the drain cleaner;
a current sensor configured to determine electrical current draw of the motor; and
a controller configured to determine occurrence of a distal end of the cable encountering a point of interest in an enclosed region based on data received from the current sensor;
wherein the controller includes communication provisions for communicating to a mobile device, the controller communicating at least one point of interest and the linear amount of cable dispensed from the drain cleaner;
wherein the communication provisions provide wireless communication with the mobile device;
wherein the mobile device is configured to generate graphical illustrations representative of the enclosed region including the at least one point of interest with respect to the linear amount of cable dispensed from the drain cleaner.
9. The drain cleaner of claim 8 wherein the motor is a brushless DC (BLDC) motor.
10. A drain cleaner comprising:
a drain cleaning cable;
a rotatable drum, the drum storing at least a portion of the cable;
a motor for rotating the drum;
a counter configured to determine a length of the cable dispensed from the drain cleaner;
a current sensor configured to determine electrical current draw of the motor;
a controller including data storage provisions for storing data received from the counter and the current sensor, the controller configured to communicate stored data to a mobile device;
wherein the mobile device is configured to generate graphical illustrations representative of an enclosed region including data received from the current sensor with respect to the linear amount of the cable dispensed from the drain cleaner.
11. The drain cleaner of claim 10 , wherein the counter includes at least one sensor assembly including a first pickup associated with the drum and a first sensor affixed to a stationary component of the drain cleaner and in operable communication with the first pickup.
12. The drain cleaner of claim 11 , wherein the drain cleaner further comprises a cable follower, and the counter includes a second sensor assembly including a second pickup associated with the cable follower and a second sensor affixed to a stationary component of the drain cleaner and in operable communication with the second pickup.
13. The drain cleaner of claim 10 , wherein one of the controller and the mobile device is configured to determine occurrence of a distal end of the cable encountering a point of interest in an enclosed region based on data received from the current sensor.
