Description

Technical Field

[0001] The utility model mainly relates to the technical field of building construction, in particular to a foundation pit drainage system. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done.

[0003] During the foundation pit excavation stage, if there is too much water at the bottom of the foundation pit, it is necessary to drain the accumulated water to lower the water level at the bottom of the foundation pit to ensure the smooth progress of earth excavation. Otherwise, long-term accumulation of water in the foundation pit will cause the foundation pit to collapse. When the foundation pit is drained, a water pump is usually used to pump out the water in the foundation pit. However, when the water pump pumps out the water in the foundation pit, the mud and sand will also be pumped into the water pump along with the water source, causing the water pump to be blocked. Now a filter net is installed inside the water pipe to filter out the mud and sand, but long-term filtration will also cause the filter net to be blocked, which will also affect the water pump from pumping out the water source inside the foundation pit.

[0023] Please refer to the attached Figure 1-Figure 5 A foundation pit drainage system includes a water pump 1, a water pipe 2 is provided at the water inlet end of the water pump 1, a telescopic pipe 3 is provided on one side of the water pipe 2, a pumping head 4 is provided at one end of the telescopic pipe 3, a filter screen 7 is provided inside the water pipe 2, a brush 9 for cleaning the sediment on the filter screen 7 is provided inside the water pipe 2, a transmission component for driving the filter screen 7 to rotate is provided inside the water pipe 2, and a reflux component for flushing the sediment on the filter screen 7 is provided on the water pipe 2.

[0024] The specific operation process of the utility model is as follows: pull the telescopic tube 3, insert the pumping head 4 into the bottom of the foundation pit, and then start the water pump 1. The water pump 1 pumps away the water source inside the foundation pit through the pumping head 4, and the water source passes through the telescopic tube 3 conveyor belt water pipe 2 through the pumping head 4. The water source enters the water pipe 2 and passes through the filter screen 7. The filter screen 7 will filter the sediment inside the water source. The sediment passing through the filter screen 7 will drive the transmission component to drive the filter screen 7 to rotate. The filter screen 7 rotates and cooperates with the brush 9 on one side to clean up the sediment remaining on the filter screen 7 to prevent the sediment from clogging the filter screen 7. At the same time, a part of the filtered water source is extracted through the reflux component to rinse the filter screen 7. The brush 9 can keep the filter screen 7 from being blocked. When there is too much sediment accumulated in the water pipe 2, the water pipe 2 can be disassembled for cleaning or an opening can be opened below the front of the filter screen 7 inside the water pipe 2 to regularly recover sediment impurities.

[0025] Please refer to Figure 1-Figure 5 The filter screen 7 is rotatably connected to the inside of the water pipe 2, a connecting block is arranged in the middle of the filter screen 7, and the reflux component includes a reflux pump 5, which is arranged above the water pipe 2, and a reflux pipe 6 is sleeved on the water inlet and outlet ends of the reflux pump 5.

[0026] The filter screen 7 is used to filter the sediment in the water source. A connecting block is provided in the middle of the filter screen 7. The connecting block is used to cooperate with the transmission component to drive the filter screen 7 to rotate. If it is feared that the filter screen 7 mesh surface will be damaged when the connecting block is connected to the mesh surface and rotated, it can be connected to the block at the edge of the filter screen 7 through a connecting rod reinforcement rib. The reflux pipe 6 at the water inlet end of the reflux pump 5 is inserted into the water source conveyed inside the water pipe 2. The reflux pipe 6 at the water outlet end of the reflux pump 5 is aligned with the upper side of the filter screen 7. The reflux pump 5 extracts a part of the filtered water source through the reflux pipe 6 and then sprays it on the filter screen 7 to rinse the residual sediment on the filter screen 7.

[0027] Please refer to Figure 2-Figure 4 A diverter plate 8 is fixedly installed inside the water pipe 2, a brush 9 is arranged on one side of the diverter plate 8, the brush 9 is in contact with one side of the filter screen 7, the transmission assembly includes a support rod 11, the support rod 11 is rotatably connected inside the water pipe 2, a transmission plate 13 is fixedly installed on the support rod 11, a rotating rod 10 is rotatably connected inside the water pipe 2, a bevel gear set 12 is arranged between the rotating rod 10 and the support rod 11, and one end of the rotating rod 10 is fixedly connected to a connecting block arranged in the middle of the filter screen 7.

[0028] The diverter plate 8 is used to pass the water source transported inside the water pipe 2 from below to prevent the water source from passing through the entire water pipe 2, which causes the upper and lower transmission plates 13 to be subjected to the same force and unable to drive the rotation. The water source passes through the filter screen 7, and the filter screen 7 filters the sediment in the water source. The water source passes through the filter screen 7 and impacts the transmission plate 13 on the lower side, and the support rod 11 is driven to rotate through the transmission plate 13. The support rod 11 drives the rotating rod 10 to rotate through the bevel gear set 12. The rotating rod 10 rotates through the connecting block set in the middle of the filter screen 7. The filter screen 7 can clean the entire filter screen 7 by rotating the brush 9. The residual silt on the surface can be cleaned up, so as to prevent the silt remaining on the filter screen 7 from being blocked due to excessive silt, and the water source cannot pass through the filter screen 7. A block that can be switched can be opened below the water pipe 2 on the front side of the filter screen 7. By opening the block, an opening is opened in the water pipe 2 below the front of the filter screen 7, and the silt filtered by the filter screen 7 is cleaned up through this opening to prevent the entire water pipe 2 from being blocked due to excessive accumulation of silt. The water pipe 2 can also be arranged to be assembled from multiple pipes, and the purpose of cleaning the silt inside the water pipe 2 can also be achieved by splitting the water pipe 2.

[0029] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
