Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging mechanism for foundation drainage pumps, addressing the issue raised in the background section. In construction engineering, foundation drainage pumps are indispensable equipment, especially in deep foundation pit projects, where their efficiency and stability directly affect project progress and quality. However, traditional drainage pumps often suffer performance degradation or even damage due to clogging by impurities, thus impacting the drainage efficiency of the foundation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes an anti-blocking box and a supporting base, wherein the supporting base has fixing holes through the four corners at its lower end;

[0007] The anti-clogging box has a water inlet channel fixedly connected to its upper front side. A drain outlet for draining the foundation of the building is fixedly installed at the upper opening of the water inlet channel. A barrier grille is fixedly installed on the inner wall of the drain outlet. A sedimentation chamber is fixedly connected to the bottom of the anti-clogging box. A sewage pipe is fixedly connected to the lower middle part of the sedimentation chamber. A support plate is fixedly installed on the middle inner wall of the anti-clogging box. A drain cylinder is rotatably connected to the middle of the support plate through a rotating shaft. A filter hole is opened through the upper end of the drain cylinder. A drive motor is fixedly supported and installed on the upper rear side wall of the anti-clogging box. A first pulley is fixedly installed on the upper transmission shaft of the drive motor. A second pulley is connected to the outer end of the first pulley through a belt drive. A rotating shaft is fixedly installed in the middle of the second pulley. A rotating cover plate is fixedly installed at the bottom of the rotating shaft. A connecting pipe is rotatably connected to the bottom of the drain cylinder through a rotating shaft.

[0008] Preferably, the anti-blocking box is fixedly installed inside the upper end of the support base, and there are four fixing holes, which are symmetrically distributed at the four corners of the lower end of the support base.

[0009] Preferably, the lower end of the sedimentation chamber is conical, and a switch valve is fixedly installed at the lower opening of the sewage pipe.

[0010] Preferably, the lower end of the drain cylinder is conical, and the number of filter holes is several, which are symmetrically distributed sequentially around the upper end of the drain cylinder.

[0011] Preferably, the rotating shaft is rotatably connected to the middle of the upper end of the anti-blocking box via a rotating shaft.

[0012] Preferably, the rotating cover is fixedly installed on the upper end of the drain cylinder.

[0013] Preferably, the rear end of the connecting pipe is fixedly installed through the rear end of the anti-blocking box, and a connecting flange is fixedly installed at the opening at the rear end of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When the water inlet channel is used in conjunction with the drainage outlet to guide drainage of the foundation of a building project, the water generated inside the foundation will be discharged into the anti-clogging box through the drainage outlet and the water inlet channel. When the water generated inside the foundation is discharged into the anti-clogging box through the drainage outlet and the water inlet channel, the blocking grid will block larger impurities at the top of the drainage outlet. At the same time, the sedimentation chamber will treat the water entering the anti-clogging box to settle, so that the impurities inside the foundation water will settle to the bottom of the sedimentation chamber under the action of their own gravity. As the water level of the sedimentation chamber gradually rises, the upper layer of water will be discharged into the drainage cylinder through the filter hole, so that the water will be filtered again through the filter hole. The filtered water will be discharged into the drainage pump through the connecting pipe, thereby realizing the sedimentation and filtration of the foundation water and avoiding the drainage pump from clogging when draining the foundation.

[0016] 2. This utility model also allows for the discharge and cleaning of accumulated water and impurities at the bottom of the sedimentation chamber via the drain pipe when the valve is opened. Simultaneously, by controlling the start of the drive motor, the first pulley rotates, which in turn drives the second pulley via belt transmission. The second pulley then rotates the rotating shaft, which in turn rotates the drain cylinder via the rotating cover. As the drain cylinder rotates, impurities blocked by the filter holes are ejected by the centrifugal force generated by the rotation of the drain cylinder, preventing clogging of the filter holes over time. Thus, the anti-clogging box not only prevents clogging of the foundation drainage pump but also facilitates maintenance and cleaning of the anti-clogging box. Attached Figure Description

The four corners of the lower end of the support base 2 are provided with fixing holes 3, and there are four fixing holes 3, which are symmetrically distributed at the four corners of the lower end of the support base 2, so that the support base 2 can be installed and fixed by pre-embedded bolts in conjunction with the fixing holes 3.

[0023] The anti-clogging box 1 has a water inlet trough 4 fixedly connected to its upper front side. The length and installation position of the water inlet trough 4 are selected according to the actual construction conditions of the building foundation. A drain outlet 5 for draining the building foundation is fixedly installed at the upper opening of the water inlet trough 4. A baffle grating 6 is fixedly installed on the inner wall of the drain outlet 5 to block larger impurities at the upper end of the drain outlet 5, preventing them from clogging the drain outlet 5 and the water inlet trough 4. A sedimentation chamber 7 is fixedly connected to the bottom of the anti-clogging box 1. The lower end of the sedimentation chamber 7 is conical. A drain pipe 8 is fixedly connected to the middle of the lower end of the sedimentation chamber 7. A switch valve is fixedly installed at the lower opening of the drain pipe 8. A support plate 9 is fixedly installed on the inner wall of the middle part of the anti-clogging box 1. A drain cylinder 10 is rotatably connected to the middle of the support plate 9 through a rotating shaft. The lower end of the drain cylinder 10 is conical. A filter hole 1 is opened through the upper end of the drain cylinder 10. 1. The filter holes 11 are numerous and symmetrically distributed at the top of the drain cylinder 10. A drive motor 12 is fixedly installed on the rear side wall of the top of the anti-clogging box 1. A first pulley 13 is fixedly installed on the transmission shaft of the drive motor 12. A second pulley 14 is connected to the outer end of the first pulley 13 via belt drive. A rotating shaft 15 is fixedly installed in the middle of the second pulley 14. The rotating shaft 15 is rotatably connected to the middle of the top of the anti-clogging box 1 via a rotating shaft. A rotating cover plate 16 is fixedly installed at the bottom of the rotating shaft 15. The rotating cover plate 16 is fixedly installed at the top of the drain cylinder 10. A connecting pipe 17 is rotatably connected to the bottom of the drain cylinder 10 via a rotating shaft. The rear end of the connecting pipe 17 is fixedly installed through the rear end of the anti-clogging box 1. A connecting flange 18 is fixedly installed at the opening at the rear end of the connecting pipe 17, so that the connecting pipe 17 is connected to the drain pump through the connecting flange 18.

[0024] Working Principle: In use, this utility model uses pre-embedded bolts and fixing holes 3 to install and fix the support base 2 at a drainage point lower than the building foundation. When the support base 2 is installed and fixed at the drainage point lower than the building foundation, the water inlet 4 and the drainage outlet 5 guide the drainage of the building foundation. When the water inlet 4 and the drainage outlet 5 guide the drainage of the building foundation, the water generated inside the foundation will be discharged into the anti-blocking box 1 through the drainage outlet 5 and the water inlet 4. When the water generated inside the foundation is discharged into the anti-blocking box 1 through the drainage outlet 5 and the water inlet 4, the blocking grille 6 will block the drainage. Larger impurities at the top of the water inlet 5 are blocked, while the water entering the anti-clogging box 1 is treated by sedimentation in the sedimentation chamber 7. The impurities in the water in the foundation are settled to the bottom of the sedimentation chamber 7 under their own gravity. As the water level in the sedimentation chamber 7 gradually rises, the upper water will be discharged into the drainage cylinder 10 through the filter hole 11, so that the water is filtered again through the filter hole 11. The filtered water will be discharged into the drainage pump through the connecting pipe 17, thereby realizing the sedimentation and filtration of the water in the foundation and preventing the drainage pump from being blocked when draining the foundation.

[0025] When the foundation water is drained, the valve fixedly installed at the lower opening of the drain pipe 8 is opened. When the valve is opened, the sediment at the bottom of the sedimentation chamber 7 can be discharged and cleaned out through the drain pipe 8. At the same time, the drive motor 12 is turned on. When the drive motor 12 is turned on, it drives the first pulley 13 to rotate. When the first pulley 13 rotates, it drives the second pulley 14 to rotate through the belt drive. When the second pulley 14 rotates, it drives the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, it drives the drain cylinder 10 to rotate through the rotating cover plate 16. When the drain cylinder 10 rotates, the impurities blocked by the filter holes 11 are cleaned and thrown out by the centrifugal force generated by the rotation of the drain cylinder 10, thus preventing the filter holes 11 from becoming blocked after long-term use. In this way, the anti-blocking box 1 can prevent the foundation drainage pump from being blocked, and at the same time, facilitate the maintenance and cleaning of the anti-blocking box 1.
