The transmission ball one 17 and the transmission ball two 19 are in transmission connection, and a cross groove 40 is opened on the surface of the limit cover 20.

[0043] Among them, a water pump 27 is fixedly arranged on the bottom wall of the installation platform 1. A second water outlet pipe 29 is fixedly arranged at the water outlet of the water pump 27. A third water outlet pipe 30 is fixedly arranged on the bottom wall of the installation platform 1. The second water outlet pipe 29 communicates with the third water outlet pipe 30. A first water inlet pipe 8 is fixedly arranged between the wheel cover 9 and the third water outlet pipe 30 in a through manner. A first water outlet pipe 10 is fixedly arranged through the side wall of the wheel cover 9. A second water inlet pipe 13 is fixedly arranged between the water tank 15 and the telescopic sleeve 7 in a through manner. A fourth water outlet pipe 31 is fixedly arranged between the second water outlet pipe 29 and the water tank 15. A pressure relief valve 32 is fixedly arranged on the fourth water outlet pipe 31.

[0044] Among them, a first drill bit blade 35 is fixedly arranged on the side wall of the rotating cylinder 26. A second drill bit blade 36 is slidably arranged on the side wall of the rotating cylinder 26. The first drill bit blade 35 is slidably connected with the second drill bit blade 36.

[0045] Among them, a first cross rack 33 is fixedly arranged at the bottom of the first transmission ball 17. A second cross rack 34 is fixedly arranged at the top of the second transmission ball 19. The first cross rack 33 is meshed and linked with the second cross rack 34.

[0046] It should be noted that when the rotating cylinder 26 rotates clockwise, the first drill bit blade 35 and the second drill bit blade 36 form a bottomless bowl-shaped drill bit. When the rotating cylinder 26 rotates counterclockwise, the second drill bit blade 36 will slide into the first drill bit blade 35. Each direction of the cross groove 40 corresponds to the direction where the support assembly 3 is located. The function of the second transmission ball 19 is to amplify the rotation angle of the swing rod 14 relative to the installation platform 1 and improve the sensitivity of the device.

[0047] During specific use: At the beginning, the pressure relief valve 32 is in a closed state. Hold the installation platform 1 horizontally, and try to make all four support components 3 perpendicular to the installation platform 1 and their bottoms touch the bottom ground of the water. Start the water pump 27. After the water flows out of the water pump 27, it flows through the second outlet pipe 29 and the third outlet pipe 30 and then into the wheel cover 9 through the first inlet pipe 8. After driving the impeller 11 to rotate, it flows out from the first outlet pipe 10. The rotation of the impeller 11 drives the transmission rod 21 to rotate, and the rotation of the transmission rod 21 drives the threaded rod 22 to rotate. Under the action of the threaded sleeve 12, the threaded rod 22 moves downward in a rotating manner. The threaded rod 22 drives the conical drill 23 to move synchronously. The conical drill 23 drives the first friction ring 24 and then drives the second friction ring 25 to move. The second friction ring 25 drives the rotating cylinder 26 to rotate downward. The rotating cylinder 26 drives the bowl-shaped drill bit composed of the first drill bit blade 35 and the second drill bit blade 36 to move downward. The bowl-shaped drill bit drills into the sediment at the bottom of the water. After the drill bit drills in, the sediment flows back above the first drill bit blade 35 and the second drill bit blade 36. These sediments press on the first drill bit blade 35 and the second drill bit blade 36 to assist in fixing the support component 3. If the bowl-shaped drill bit encounters a gravel area at the bottom of the water, the resistance received by the first drill bit blade 35 and the second drill bit blade 36 is relatively large, resulting in the resistance received by the rotating cylinder 26 being greater than the friction force between the first friction ring 24 and the second friction ring 25. The first friction ring 24 and the second friction ring 25 slide relative to each other, and the conical drill 23 starts to protrude from the rotating cylinder 26. The conical drill 23 rotates and drills into the gravel area, thereby fixing the support component 3. After all the support components 3 are fixed, at this time, the impeller 11 stops rotating under the action of resistance, resulting in the pressure in the first inlet pipe 8 and the third outlet pipe 30 gradually increasing. After the pressure is greater than the threshold pressure of the pressure relief valve 32, the pressure relief valve 32 opens, and the water flow can flow through the fourth outlet pipe 31 into the water tank 15. If the top surface of the installation platform 1 is not horizontal, the bottom surface of the installation platform 1 is not perpendicular to the normal line of the swing rod 14. The swing rod 14 deflects towards one of the support components 3 in the groove of the limit cover 20. At this time, the top height of this support component 3 is lower than the top height of the opposite support component 3. The swing rod 14 rotates relative to the installation platform 1. The rotation of the swing rod 14 drives the second transmission ball 19 to rotate. The rotation of the second transmission ball 19 drives the first transmission ball 17 to rotate in the opposite direction. The rotation of the first transmission ball 17 drives the lever 18 to move. The movement of the lever 18 drives the baffle 16 close to this support component 3 to move downward. The downward movement of the baffle 16 makes it no longer block the second inlet pipe 13. The water flow flows through the second inlet pipe 13 into the telescopic sleeve 7, causing the telescopic rod 6 to move away from the telescopic sleeve 7, thereby raising this support component 3. The device will repeat this operation on multiple support components 3 until the top surface of the installation platform 1 is finally horizontal;

[0048] If the installation platform 1 biases towards the two support components 3 at the same time, due to the effect of the cross groove 40 on the surface of the limit cover 20, the swing rod 14 will only first bias towards the direction of one of the two support components 3, perform a leveling operation, and when the swing rod 14 returns to the center of the cross groove 40 again, it will bias towards the direction of the other support component 3 and repeat the leveling operation.

[0049] In short, if those of ordinary skill in the art are inspired by this and, without departing from the purpose of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
