[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example: Reference Figure 1-5 The water control device for a foundation pit shown in the figure comprises a water collecting cylinder 1, which is embedded in the bottom of the foundation pit, an introduction cone 2 is fixed to the bottom of the water collecting cylinder 1, a plurality of fixing rods 3 are fixed to the inner wall of the water collecting cylinder 1, a fixing cylinder 4 is fixed to the other end of the plurality of fixing rods 3, a carrier plate 5 is fixed to the bottom of the fixing cylinder 4, a plurality of slide grooves are opened on the carrier plate 5, a slide rod 6 is slidably inserted in the slide groove, the cross section of the slide groove is a rectangular structure, the plurality of slide rods 6 decrease in length from long to short, a first float 7 is fixed to the bottom end of the slide rod 6, and the plurality of first floats are fixed to the bottom end of the first float 7. The balls 7 are arranged in a stepped manner in the longitudinal direction. A limit block 8 is fixed on the top of the slide bar 6. A plug 9 is fixedly installed on the top of the limit block 8. Multiple plugs 9 are located inside the fixed cylinder 4. A socket 10 is fixedly installed on the top of the inner side of the fixed cylinder 4. The socket 10 is connected to the city power supply line. The socket 10 is provided with a socket 11 adapted to the plug 9. A plurality of pumping assemblies are provided on the water collecting cylinder 1. The plurality of plugs 9 are the same in number and correspond one to one with the plurality of pumping assemblies. The pumping assemblies are used to discharge water in the foundation pit.

[0024] The rainwater at the bottom of the foundation pit is gathered by the water collecting cylinder 1. The rainwater will make the first float 7 float up. The first float 7 can push the plug 9 to move upward so that the plug 9 is inserted into the corresponding socket 11 on the socket 10. In this way, the pumping assembly connected by the plug 9 through the wire is powered on and the rainwater in the foundation pit can be discharged in time. The multiple first floats 7 are designed to be arranged in a stepped manner in the longitudinal direction, so that the multiple first floats 7 float up one by one as the water volume increases. In this way, the multiple plugs 9 will be inserted into the corresponding sockets 11 on the socket 10 in turn, so as to adjust the number of pumping assemblies in operation, so that the rainwater in the foundation pit can be drained in time.

[0025] The pumping assembly includes a water pump 12, a water pipe 13, a drainage pipe 14, a second float 15 and a counterweight 16. The water pump 12 is arranged outside the water collecting cylinder 1, one end of the water pipe 13 is connected to the water inlet of the water pump 12, one end of the drainage pipe 14 is connected to the drainage outlet of the water pump 12, the second float 15 is located inside the water collecting cylinder 1, the counterweight 16 is fixedly installed at the bottom of the second float 15, and the counterweight 16 is fixedly sleeved on the outside of the water pipe 13, a limiting rod 18 is fixed on the top of the second float 15, and a U-shaped plate 17 is slidably sleeved on the outside of the limiting rod 18, and the U-shaped plate 17 is fixedly installed on the top of the water collecting cylinder 1;

[0026] With the help of the second float 15, the water inlet of the water pipe 13 is driven to float up, and the counterweight 16 can ensure that the water inlet of the water pipe 13 is always located below the second float 15, so that the water inlet of the water pipe 13 can change with the water level. In this way, the solid objects at the bottom of the water collecting cylinder 1 will not block the normal water inlet of the water pipe 13. With the help of the U-shaped plate 17 and the limit rod 18 cooperating with each other, the second float 15 can be limited to move only in the longitudinal direction. In this way, multiple water pipes 13 can be effectively prevented from entangled with each other inside the water collecting cylinder 1.

[0027] The water collecting cylinder 1 is provided with two symmetrically arranged reserved grooves 19 for providing hooking points when the water collecting cylinder 1 is taken out.

[0028] A plurality of reinforcing plates 20 are fixed to the outer wall of the water collecting cylinder 1. The plurality of reinforcing plates 20 are distributed in a circular array. Through holes 21 are provided on the reinforcing plates 20. Reinforcing nails 22 are slidably inserted into the through holes 21.

[0029] With the help of the introduction cone 2, the water collecting cylinder 1 can be more easily embedded in the bottom of the foundation pit. With the help of the reinforcement plate 20 and the reinforcement nails 22 thereon, the position of the water collecting cylinder 1 in the foundation pit can be reinforced to improve the stability of the water collecting cylinder 1 after being fixed at the bottom of the foundation pit.

[0030] Working principle of this utility model:

[0031] When in use, first embed the water collecting cylinder 1 and the introduction cone 2 into the bottom of the foundation pit, so that the top of the water collecting cylinder 1 is level with the bottom of the foundation pit, and use a hammer to knock the reinforcement nails 22 so that the reinforcement nails 22 cooperate with the reinforcement plate 20 to reinforce the position of the water collecting cylinder 1 in the foundation pit. In rainy weather, rainwater gathers at the bottom of the foundation pit and flows into the inside of the water collecting cylinder 1 along the bottom of the foundation pit. As the amount of water continues to increase, the rainwater will make the first float 7 float up. As the first float 7 moves up to a specified height, the plug 9 on the top of the first float 7 will be inserted into the corresponding socket 11 on the socket 10. At this time, the plug 9 is energized and will transmit electrical energy to the corresponding water pump 12 with the help of a wire, forcing the water pump 12 to operate, and the water in the water collecting cylinder 1 is discharged to the outside of the foundation pit along the water pipe 13 to prevent water accumulation in the foundation pit.

[0032] Because the plurality of first floating balls 7 are arranged in a stepped manner in the longitudinal direction, the plurality of plugs 9 on the plurality of first floating balls 7 will be inserted into the sockets 11 on the socket 10 one by one in an orderly manner as the water level in the water collecting cylinder 1 rises, so that the number of powered water pumps 12 increases accordingly. The rise in water level indicates that the drainage speed is lower than the speed at which the water in the foundation pit gathers. Therefore, increasing the number of running water pumps 12 can increase the drainage speed, so that the rainwater in the water collecting cylinder 1 can be discharged to the outside of the foundation pit in time, and the second floating balls 15 will float up with the help of rainwater, and when the second floating balls 15 float up, they will drive the water pipe 13 into the foundation pit. The water outlet floats up, and the counterweight 16 can ensure that the water inlet of the water pipe 13 is always located below the second float 15. In this way, it is ensured that the water pipe 13 can be filled with water in an orderly manner to prevent solid objects at the bottom of the water collecting cylinder 1 from clogging the water pipe 13. The U-shaped plate 17 and the limit rod 18 cooperate with each other to limit the second float 15 to move only in the longitudinal direction, which can prevent the second float 15 from moving randomly in the water collecting cylinder 1, thereby preventing multiple water pipes 13 from being entangled with each other inside the water collecting cylinder 1. The solid objects inside the water collecting cylinder 1 are cleaned regularly to prevent the solid objects from affecting the normal use of the water collecting cylinder 1.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
