[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5As shown, a deep foundation pit local drainage construction tool includes a first drainage pipe 2, a second drainage pipe 3 and a blocking ring 1 sleeved on the first drainage pipe 2, a side wall of the first drainage pipe 2 is provided with an interlayer 8, and a motor 4 fixedly connected to the first drainage pipe 2 is provided above the interlayer 8, the main shaft of the motor 4 is fixedly connected to a worm 16, the other end of the worm 16 is fixedly connected to a distribution plate 13, and the side wall of the worm 16 is meshed with a worm gear 15, a pull rope 10 fixedly connected to the blocking ring 1 is wound on the distribution plate 13, and the central axis of the worm gear 15 passes through a fixed connection with the first drainage pipe 2 is rotatably connected to the transmission shaft 14. The lower half of the transmission shaft 14 is sleeved with a plurality of rollers 11 distributed in a linear array and rotatably connected to the inner wall of the interlayer 8. A limiting hole 9 corresponding to the position of the roller 11 is opened between the inner wall of the interlayer 8 and the outer wall of the first drain pipe 2. A spring rod 7 is fixedly connected in the limiting hole 9. A pull rope 10 is also fixedly connected between the telescopic end of the spring rod 7 and the side wall of the roller 11. The pull rope 10 located in the limiting hole 9 is fixedly connected to the roller 11 through the cylinder body that passes through the spring rod 7. The inner wall of the blocking ring 1 is opened with a clamping hole for clamping the telescopic end of the spring rod 7.

[0025] With this technical solution, by setting the motor 4 to rotate and drive the distribution plate 13 and the worm 16 to rotate, the distribution plate 13 drives the blocking ring 1 to move its position, and the worm 16 drives the telescopic end of the spring rod 7 used to clamp the blocking ring 1 to move. The device achieves the effect of automatically controlling the movement of the blocking ring 1 and automatically fixing its position. Specifically, the distribution plate 13 rotates, and the position of the blocking ring 1 is changed by the pull rope 10 wound on it. The worm 16 rotates, driving the worm wheel 15 to rotate, and the rotation of the worm wheel 15 drives the transmission shaft 14 to rotate. The transmission shaft 14 rotates to drive the drum 11 to rotate, and the drum 11 rotates to pull the pull rope 10 fixed to the spring rod 7, thereby driving the telescopic end of the spring rod 7 used to clamp the blocking ring 1 to retract. When the position of the blocking ring 1 moves beyond the target position, the motor 4 is set to reverse a certain number of turns so that the positions of the clamping hole and the limiting hole 9 on the blocking ring 1 coincide with each other, and after the drum 11 is reversed, the pulling force on the pull rope 10 will be eliminated, so that the telescopic end of the spring rod 7 at the limiting hole 9 extends out and enters the clamping hole, thereby fixing the position of the blocking ring 1.

[0026] like Figure 2 、 Figure 3 and Figure 4 As shown, a protrusion 12 is fixedly connected to one side of the end of the drum 11, and a blocking block 17 for blocking the rotation of the protrusion 12 is also fixedly connected to the inner wall of the interlayer 8. A spring rod 7 is also provided between the drum 11 and the transmission shaft 14. The fixed end of the spring rod 7 located in the drum 11 is fixedly connected to the transmission shaft 14, and the telescopic end is damped with the inner wall of the drum 11.

[0027] By adopting this technical solution, a spring rod 7 is arranged inside the drum 11, so that when the drum 11 rotates following the transmission shaft 14, the protrusion 12 encounters the blocking block 17, which can stop the rotation of the drum 11. Since the friction between the spring rod 7 inside the drum 11 and the drum 11 is greater than the spring force of the spring rod 7 located at the limiting hole 9, the drum 11 will remain stationary until the motor 4 starts to reverse. In addition, the positions of the blocking block 17 and the protrusion 12 are designed. When the telescopic end of the spring rod 7 located at the limiting hole 9 is extended and retracted, the distance generated by pulling the pull rope 10 is exactly equal to the distance the protrusion 12 rotates to the blocking block 17.

[0028] like Figure 2 As shown, the bottom end of the inner wall of the first drain pipe 2 and the top end of the outer wall of the second drain pipe 3 are connected by threads. The top end of the first drain pipe 2 is rotatably connected to the connecting pipe 6, and the turbine 5 is also fixedly connected thereto.

[0029] By adopting this technical solution, a threaded connection is set between the first drain pipe 2 and the second drain pipe 3, so that the second drain pipe 3 can be removed from the first drain pipe 2, which facilitates the maintenance of the device. By setting a turbine 5 and a connecting pipe 6, the device can be rotated under the influx of water. During the rotation process, the impact force of the water flow and the centrifugal force of the rotation of the device itself can prevent the holes in the drainage pipe from being blocked.

[0030] Working principle: Start the motor 4, which drives the distribution disk 13 and the worm 16 to rotate. The rotation of the distribution disk 13 will drive the blocking ring 1 to rise and fall. The rotation of the worm 16 will drive the worm gear 15 to rotate. The rotation of the worm gear 15 will drive the transmission shaft 14 to rotate and then drive the drum 11 to rotate. The rotation of the drum 11 will pull the pull rope 10 and thus shrink the telescopic end of the spring rod 7. When the motor 4 rotates, the blocking ring 1 will move and cross the target position. After that, the motor 4 reverses, driving the blocking ring 1 to move to the target position. Since the reversal of the motor 4 will drive the drum 11 to reverse, the reversal of the drum 11 will eliminate the pulling force on the pull rope 10, so that the telescopic end of the spring rod 7 at the limiting hole 9 will extend and enter the clamping hole, fixing the position of the blocking ring 1.

[0031] The wiring diagram of the motor 4 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 4 are not explained in detail.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
