Floating-type aquatic support apparatus

1. A floating-type on-water support apparatus comprising:

a ball;

a floating unit including a floating part, wherein the floating part has an upper plate supporting the ball so that the ball is rotatable, an interior formed to be hollow, and a lower plate provided with a spherical surface portion and floats on water;

a support rod coupled to the ball and having one end exposed above the water so that a structure is installable thereon and the other end heavier than the one end so as to stand vertically to be accommodated in the floating part; and

a base unit having one end installed on a lower portion of the support rod to support the support rod and the other end in roll contact with the spherical surface portion.

2. A floating-type on-water support apparatus comprising:

a ball;

a floating unit including a floating pan, wherein the floating part has an upper plate supporting the ball so that the ball is rotatable, an interior formed to be hollow, and a lower plate provided with a spherical surface portion and floats on water;

a support rod having one end exposed above the water so that a structure is installable thereon and the other end coupled to the ball to stand vertically to be accommodated in the floating part; and

a center pendulum positioned to be rolled on the spherical surface portion to press a lower end of the support rod so as to allow the support rod to stand.

3. The floating-type on-water support apparatus of claim 2 , wherein the lower end of the support rod surrounds an upper portion of the center pendulum so that the center pendulum is not separated from the support rod.

4. The floating-type on-water support apparatus of claim 3 , wherein the support rod is supported by the center pendulum using a bearing.

5. The floating-type on-water support apparatus of any one of claim 1 , wherein the support rod is slidably coupled to pass through the ball.

6. The floating-type on-water support apparatus of claim 5 , wherein:

a guide groove is formed in the ball along a circumferential surface passing through the support rod; and

the floating unit further includes a restriction protrusion fitted into the guide groove to restrict rotation of the ball about an axis of the support rod.

7. A floating-type on-water support apparatus comprising:

a floating unit including a floating part of which an interior is formed to be hollow so that the floating part floats on water and in which a spherical surface portion is formed on a lower surface in the interior;

a support unit accommodated in the floating part and including an upper support rod coupled to an upper portion of the floating part and a lower support rod having one end coupled to the upper support rod using a universal joint and the other end heavier than the one end to stand vertically;

a base unit having one end installed on the other end of the lower support rod to support the lower support rod and the other end in roll contact with the spherical surface portion; and

an installation base exposed above the floating unit so that a structure is installable on one end thereof and coupled to the lower support rod.

8. A floating-type on-water support apparatus comprising:

a floating unit including a floating part of which an interior is formed to be hollow so that the floating part floats on water and in which a spherical surface portion is formed on a lower surface in the interior;

a support unit accommodated in the floating part and having an upper support rod coupled to an upper portion of the floating part and a lower support rod coupled to the upper support rod using a universal joint;

a center pendulum positioned to be rolled on the spherical surface portion to press a lower end of the lower support rod so as to allow the lower support rod to stand; and

an installation base exposed above the floating unit so that a structure is installed one end thereof and coupled to the lower support rod.

9. The floating-type on-water support apparatus of claim 8 , wherein the lower support rod surrounds an upper portion of the center pendulum so that the center pendulum is not separated from the lower support rod.

10. The floating-type on-water support apparatus of claim 9 , wherein the lower support rod is supported by the center pendulum using a bearing.

11. The floating-type on-water support apparatus of any one of claim 7 , wherein the upper support rod is coupled to an upper portion of the floating part to be vertically slidable.

12. The floating-type on-water support apparatus of any one of claim 2 , wherein the support rod is slidably coupled to pass through the ball.

13. The floating-type on-water support apparatus of any one of claim 8 , wherein the upper support rod is coupled to an upper portion of the floating part to be vertically slidable.
