Technical Field

[0001] The utility model relates to the technical field of foundation pits, in particular to a drainage device for foundation pits. Background Art

[0002] In current life, the foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. During the excavation of the foundation pit, sometimes groundwater may be dug to the bottom, causing groundwater to seep out of the foundation pit, thereby accumulating water at the bottom of the foundation pit, affecting the next step of construction. Therefore, a drainage device is needed to drain the interior of the foundation pit.

[0003] Since the water in the foundation pit is generally mixed with mud and sand, the water is generally filtered through a filter screen when draining. The filter screen needs to be cleaned after a period of time to avoid clogging. When cleaning, the filter screen generally needs to be manually disassembled and cleaned, which is more cumbersome, thus affecting the convenience of the drainage device when cleaning the filter screen; since the water in the foundation pit is generally turbid, the water at the bottom is turbid due to sedimentation, the drainage device generally puts the suction pipe into the water when draining the foundation pit. At this time, the water pipe is located on the surface of the foundation pit, and it is not easy to pump water on the water surface; the drainage device is generally fixed to the inside of the foundation pit by an inserted rod. Since there is water inside the foundation pit, the land is relatively soft, and the inserted rod is easy to loosen, which can easily affect the stability of the drainage device when it is used.

Since the structure of the retaining net is an inverted cone structure, it is not easy for impurities to adhere to the surface of the retaining net. Since the water pump hose is fixed on one side of the floating block, the water pump hose can be used to draw water from the surface layer, avoiding the water pump hose from sucking in muddy water precipitated at the bottom. Then the accumulated water is discharged through the water pump, so as to realize the function of the drainage device to extract surface water, and it is not easy to suck in the sediment at the bottom.

[0027] Furthermore, if Figure 3As shown, a cleaning mechanism 3 is provided on one side of the filter 101, and the interior of the cleaning mechanism 3 includes a scraper 301 and a cleaning component 302. The surface of the filter 101 is provided with the scraper 301, and the surface of the scraper 301 is tightly fitted with the surface of the filter 101. The surface of the cover 103 is provided with the cleaning component 302, and the cleaning component 302 is composed of a servo motor 3021, a rotating rod 3022 and an arc-shaped slide 3023. The surface of the cover 103 is fixed with the arc-shaped slide 3023, and the surface of the arc-shaped slide 3023 is provided with the rotating rod 302 2. The rotating rod 3022 is detachably connected to one end of the scraper strip 301 by screws. The rotating rod 3022 rotates along the arc-shaped slide 3023. A servo motor 3021 is installed inside the rain shield 102. The model of the servo motor 3021 can be selected from the SZ series. The input end of the servo motor 3021 is electrically connected to the output end of the control row key 105. The output end of the servo motor 3021 is fixed with a rotating shaft through a coupling.

[0029] Furthermore, if Figure 4 As shown, the interior of the drainage bucket 1 is provided with a floating pumping mechanism 4, and the interior of the floating pumping mechanism 4 is provided with a guide column 401 and a floating pumping component 402. The interior of the drainage bucket 1 is fixed with a guide column 401, and the surface of the guide column 401 is provided with a floating pumping component 402. The interior of the floating pumping component 402 includes a retaining net 4021, a pumping hose 4022 and a floating block 4023. The surface of the guide column 401 is provided with a floating block 4023, and the floating block 4023 and the guide column 401 slide with each other. A pumping hose 4022 is fixed to one end of the floating block 4023, and one end of the pumping hose 4022 passes through the cover plate 103 and is connected to one end of the water pump 104. The other end of the pumping hose 4022 is fixed with a retaining net 4021, and the structure of the retaining net 4021 is an inverted cone structure.

[0030] When in use, the float 4023 always floats on the surface of the water under the action of its own buoyancy, and the float 4023 can be guided under the action of the guide column 401, and then the control row key 105 is operated to make the control row key 105 control the water pump 104 to make the water pump 104 suck the accumulated water inside the drainage bucket 1 into the inside of the retaining net 4021. Since the structure of the retaining net 4021 is an inverted cone structure, impurities are not easy to adhere to the surface of the retaining net 4021. Since the suction hose 4022 is fixed on one side of the float 4023, the suction hose 4022 can draw in surface water to prevent the suction hose 4022 from sucking in muddy water settled at the bottom. Then the accumulated water is discharged through the water pump 104 to realize the function of the drainage device to extract surface water.

[0031] Working principle: When in use, first place the drainage device to the water accumulation place of the foundation pit, insert the plug rod 2024 into the inside of the foundation pit, and make the plug rod 2024 more stable under the action of the reinforcement teeth 2021. At this time, the bottom plate 201 is in contact with the surface of the foundation pit, and then put the gravity block 2022 into the groove 2023. Under the action of the gravity block 2022, the gravity of the bottom plate 201 is increased, making the bottom plate 201 more stable, so as to realize the stabilizing function of the drainage device, thereby improving the stability of the drainage device when in use.

[0032] At this time, the accumulated water in the foundation pit enters the interior of the drainage bucket 1 through the filter net 101. Under the action of the filter net 101, impurities in the accumulated water can be intercepted. At this time, the float 4023 always floats on the surface of the water body under the action of its own buoyancy, and the float 4023 can be guided under the action of the guide column 401. Then, the control row key 105 is operated to control the water pump 104 to make the water pump 104 suck the accumulated water inside the drainage bucket 1 into the retaining net 4021. Since the structure of the retaining net 4021 is an inverted cone structure, impurities are not easily attached to the surface of the retaining net 4021. Since the suction hose 4022 is fixed on one side of the float 4023, the suction hose 4022 can draw in surface water to prevent the suction hose 4022 from sucking in muddy water settled at the bottom. Then, the accumulated water is discharged through the water pump 104 to realize the function of the drainage device to extract surface water, and it is not easy to suck in the bottom sediment.

[0033] After a period of time, the control row key 105 can be operated to make the control row key 105 control the servo motor 3021 to work. Under the action of the servo motor 3021, the rotating rod 3022 is driven to rotate along the arc-shaped slide 3023, driving the scraper bar 301 to rotate, so that the scraper bar 301 scrapes off the impurities attached to the surface of the filter 101. At the same time, since the scraper bar 301 and the rotating rod 3022 are detachably connected by screws, the scraper bar 301 can be easily disassembled for cleaning or replacement, so as to realize the function of the drainage device to facilitate cleaning of the filter 101, thereby improving the convenience of the drainage device in cleaning the filter 101, and finally completing the use of the drainage device.
