Apparatus to wirelessly monitor a status of a hatch
View Patent ↗Apparatus to wirelessly monitor a position of a hatch are disclosed. An example apparatus includes a hatch to be coupled to a fluid tank, a latch to secure the hatch in a closed position, and a sensor to detect whether the latch is securing the hatch in a closed position.
1. An apparatus comprising:
a hatch to be coupled to a fluid tank;
a latch to secure the hatch in a closed position;
a bracket removably couplable to a base of the hatch; and
a sensor to detect whether the latch is securing the hatch in the closed position, the sensor having a first portion coupled to a lid of the hatch and a second portion coupled to the bracket.
2. The apparatus as defined in claim 1 , wherein when the latch is securing the hatch in the closed position, the first and second portions of the sensor are aligned.
3. The apparatus as defined in claim 1 , wherein when the latch is not securing the hatch in the closed position, the first and second portions of the sensor are misaligned.
4. The apparatus as defined in claim 1 , further including a transmitter operatively coupled to the sensor, the transmitter to send a signal to an operator based on an output from the sensor.
5. The apparatus as defined in claim 4 , wherein the transmitter is a wireless transmitter operative to wirelessly communicate with an operator workstation.
6. The apparatus as defined in claim 1 , wherein the sensor is a proximity sensor, a magnetic switch, an optical sensor, a limit switch, or an acoustic sensor.
7. An apparatus comprising:
means for securing a means for closing a hatch of a tank;
a bracket removably couplable to a base of the hatch; and
means for detecting a position of the means for securing, the means for detecting including a first portion coupled to the means for closing and a second portion coupled to the bracket.
8. The apparatus as defined in claim 7 , further including means for communicating the position.
9. The apparatus as defined in claim 8 , wherein the means for communicating wirelessly communicates the position to means for monitoring the means for securing.
10. The apparatus as defined in claim 9 , wherein the means for communicating sends an alert to the means for monitoring when the means for securing is in an open position.
11. The apparatus as defined in claim 7 , wherein the means for securing is in a closed position when the first portion and the second portion of the means for detecting are in proximity to each other.
12. The apparatus as defined in claim 11 , wherein the means for securing is in an open position when the first portion and the second portion of the means for detecting are not in proximity to each other.
13. An apparatus comprising:
a hook to engage a catch of a hatch on a tank;
a first portion of a sensor to be coupled to the hook;
an adapter plate removably couplable to a base portion of the hatch adjacent the hook; and
a second portion of the sensor to be coupled to the adapter plate, the first and second portions of the sensor to cooperate to detect when the hook is engaged with the catch.
14. The apparatus as defined in claim 13 , wherein the first portion of the sensor is a target magnet.
15. The apparatus as defined in claim 13 , wherein the second portion of the sensor is a magnetic switch.
16. The apparatus as defined in claim 13 , wherein first and second portions of the sensor detect when the hook is engaged with the catch based on when the first portion is in proximity with the second portion such that the second portion detects the first portion.
17. The apparatus as defined in claim 16 , wherein the hook is to be coupled to a movable portion of the hatch and the catch is to be coupled to the base portion of the hatch.
18. The apparatus as defined in claim 17 , wherein the hook is to replace a latch provided with the hatch on the movable portion.
19. The apparatus as defined in claim 13 , wherein the adapter plate is to removably attach to a flange of the base portion used to attach the hatch to the tank.
20. The apparatus of claim 2 , wherein the first portion and the second portion are aligned along a longitudinal axis of the second portion.
21. The apparatus of claim 20 , wherein the longitudinal axis extends substantially parallel to a plane defined by a flange of the base used to attach the hatch to the tank.
22. The apparatus of claim 20 , wherein the first portion is to extend in a direction substantially transverse to a line extending between the latch and a hinge coupling the lid to the base.
