[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1: A mobile foundation pit drainage device for water conservancy projects, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and 5As shown, it includes a mobile vehicle 1, a mounting seat 2, a first drain pipe 3, a second drain pipe 4, a drain head 5, a placement seat 7, a water pump 9, a switching plate 10, a fixing plate 11, a first mounting plate 12, a screw 13 and a motor 14. The right part of the mobile vehicle 1 is fixedly connected to the mounting seat 2, the first drain pipe 3 is fixedly connected to the right side of the mounting seat 2, two second drain pipes 4 are fixedly connected to the left side of the mounting seat 2, and the second drain pipes 4 are symmetrical front and back. The water pump 9 is installed on the first drain pipe 3, and the left end of the second drain pipe 4 is fixedly connected to the drain head 5. The front and rear sides of the left part of the mobile vehicle 1 are fixedly connected to the placement seat 7, the drain head 5 is placed on the placement seat 7, the switching plate 10 is slidably connected to the mounting seat 2, and the fixing plate Circular through holes are provided at the front and rear parts of 11. Initially, the circular through hole at the rear part coincides with the water outlet of the rear second drain pipe 4, and the circular through hole at the front part is staggered with the water outlet of the front second drain pipe 4. The fixing plate 11 is fixedly connected between the front and rear sides of the switching plate 10. The fixing plate 11 is slidably connected to the mounting seat 2. A symmetrically distributed first mounting plate 12 is fixedly connected to the top of the mounting seat 2. A motor 14 is installed on the first mounting plate 12 on the front side by bolts. The screw 13 is fixedly connected to the output shaft of the motor 14. The screw 13 is rotatably connected to the first mounting plate 12 on the rear side. The screw 13 is threadedly connected to the fixing plate 11. A rubber-wrapped handle is provided on the right side of the mobile vehicle 1.
[0026] like Figure 3 As shown, it also includes a first magnet 6 and a second magnet 8. The first magnet 6 is fixed to the bottom of the drainage head 5, and the second magnet 8 is fixed to the top of the placement seat 7. When the drainage head 5 is placed on the placement seat 7, the first magnet 6 and the second magnet 8 are attracted together.
[0027] When using the device, the staff first holds the handle to push the mobile vehicle 1 to the vicinity of the foundation pit and places it there. Then, the staff takes out the drainage head 5 from the placement seat 7 and places the two drainage heads 5 in the foundation pit at a distance. The water will cover the drainage head 5. Then, the water pump 9 is started. The water in the foundation pit will first be discharged through the second drainage pipe 4 and the first drainage pipe 3 at the rear side. When the second drainage pipe 4 at the rear side is blocked by the silt of the foundation pit, the motor 14 is immediately controlled to drive the screw 13 to rotate forward, thereby driving the fixed plate 11 and the switching plate 10 to move backward, so that the circular through hole at the front of the switching plate 10 coincides with the water outlet of the second drainage pipe 4 at the front, and the water will continue to flow through the second drainage pipe 4 at the front side. The water pipe 4 is discharged from the first drainage pipe 3. At this time, the staff can repair or replace the second drainage pipe 4 at the rear side. Similarly, when the second drainage pipe 4 at the front side is also blocked by the mud in the foundation pit, the control motor 14 drives the screw 13 to rotate in the opposite direction, and the switching plate 10 will move forward and reset, and the second drainage pipe 4 at the rear side can continue to drain water. When all the water in the foundation pit is drained, the water pump 9 is turned off and the drainage head 5 is placed in its original position. In summary, the two second drainage pipes 4 can be flexibly switched by the switching plate 10, so that when the water pipe is blocked by mud, the pipe can be replaced or repaired without stopping the extraction, thereby improving the drainage efficiency.
[0028] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, it also includes a mounting frame 15, a mounting block 16, a filter plate 17, a mounting sleeve 18, a clamping block 19 and a spring 20. The mounting frames 15 are fixed to the lower part of the drain head 5. The mounting frames 15 are slidably connected to the symmetrically distributed mounting blocks 16. The mounting blocks 16 are all provided with clamping grooves. A filter plate 17 is connected between two adjacent mounting blocks 16. The filter plate 17 is slidably connected to the inner wall of the drain head 5. The front and rear sides of the mounting frame 15 are connected to the mounting sleeves 18. The clamping blocks 19 are slidably connected in the mounting sleeves 18. A spring 20 is connected between the clamping blocks 19 and the adjacent mounting sleeves 18. When the filter plate 17 is sleeved on the drain head 5, the mounting block 16 and the clamping block 19 are squeezed and matched, and the clamping block 19 will be inserted into the clamping groove of the mounting block 16.
[0029] Initially, the filter plate 17 has been installed on the drainage head 5. When the filter plate 17 is blocked by mud and needs to be replaced, the filter plate 17 is first pulled downward, and the filter plate 17 will drive the mounting block 16 to move downward. The downwardly moving mounting block 16 will squeeze the card block 19 and push it outward, and the spring 20 will be deformed. When the downwardly moving mounting block 16 passes over the card block 19, under the elastic action of the spring 20, the card block 19 moves inward and resets, and then the new filter plate 17 is installed in place. The specific operation is as follows: insert the mounting block 16 into the mounting frame 15, and the card block 19 will be inserted into the card slot of the mounting block 16. Through the cooperation of the mounting block 16 and the card block 19, the replacement of the filter plate 17 is more convenient and the work efficiency is improved.
[0030] like Figure 1 and Figure 7 As shown, it also includes a second mounting plate 21, a rotating shaft 22, a scraper 23 and a fan blade 24. The second mounting plates 21 are fixedly connected to the top of the filter plate 17. The second mounting plates 21 are rotatably connected to the rotating shaft 22. The scrapers 23 are fixedly connected to the lower part of the rotating shaft 22. The scrapers 23 are used to clean the mud and sand on the filter plate 17. The fan blades 24 are fixedly connected to the upper part of the rotating shaft 22.
[0031] When the accumulated water is pumped out through the water pump 9, the water will impact the fan blades 24. Due to the transfer of kinetic energy and momentum of the water, the fan blades 24 will be subjected to a torque, causing the fan blades 24 to rotate, thereby driving the scraper 23 to rotate together through the rotating shaft 22. The rotating scraper 23 will clean the filter plate 17 to prevent the filter plate 17 from being blocked by mud and sand, thereby improving the drainage efficiency.
[0032] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
