Description

Technical Field

[0001] The utility model relates to the field of drainage devices, and specifically relates to an automatic drainage device. Background Technique

[0002] Drainage devices are important equipment for draining accumulated water or wastewater in various scenarios. In residential, commercial buildings and industrial factories, drainage devices ensure the dryness and hygiene inside the buildings. A reasonable drainage system design can effectively prevent problems such as rainwater backflow and ground waterlogging, protecting the structure and decoration of the buildings. For example, in roof drainage, by setting gutters, rainwater inlets and drainage pipes, rainwater can be quickly drained away to prevent roof waterlogging and leakage.

[0003] In the prior art, such as a construction road surface drainage device with the publication number CN215105004U, the construction road surface drainage device collects and processes the accumulated water uniformly. There are feet and water inlets at the bottom of the suction pipe. The water inlets suck the accumulated water into the storage tank for unified collection and processing, avoiding the accumulation of water in the construction site and affecting the environment, and at the same time avoiding the safety hazard caused by the slippery ground.

[0004] In the above patent, a pump body and a control valve are arranged on the connecting pipe and the water inlet pipe. The accumulated water is pumped into the storage tank through the water inlet, the connecting pipe and the water inlet pipe in sequence by the pump body. Since there are many sludge, debris and impurities in the construction site, when the pump body pumps water, these sludge, gravel and slag will block the water inlet, reducing the water inlet efficiency. Moreover, fine particles are likely to remain in the water inlet pipe. When the residues accumulate too much, it is easy to cause the blockage of the water inlet pipe and affect the drainage efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an automatic drainage device, which solves the problems put forward in the above background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: an automatic drainage device, including a fixed bracket and a water pump, the water pumping end of the water pump is communicated with a water collector, and one end of the water collector is communicated with a number of monomer structures for pumping water and filtering.

[0007] The monomer structure includes a water suction pipe, a wrapping shell, a driving component, a double-layer filter plate for rotation and a sludge suction pipe penetrating through the water suction pipe. The end of the water suction pipe is fixedly connected with the wrapping shell. The double-layer filter plate includes filter plate A and filter plate B stacked together. The bottom ends of filter plate A and filter plate B are both in an inverted cone shape, and there is a gap between the two. The pore sizes of filter plate A and filter plate B decrease in sequence. There is a notch for water inlet at the bottom end of the wrapping shell, and the end of the sludge suction pipe is installed inside the double-layer filter plate.

[0008] Preferably, one end of the water suction pipe close to the wrapping shell is made of a rigid material, and the other end is made of a telescopic soft material.

[0009] Preferably, the wrapping shell includes a shell cover, a shell body and a threaded cylinder. The threaded cylinder is fixedly connected to the shell cover, and the shell body is threadedly connected to the threaded cylinder.

[0010] Preferably, the upper ends of the filter plate A and the filter plate B are both annular, and the two are fixed by screws.

[0011] Preferably, the driving assembly includes a motor fixed to the shell body, a grinding wheel A and an annular grinding wheel B. The output rotating shaft of the motor is fixedly connected to the grinding wheel A. The grinding wheel A is in close contact with the grinding wheel B, and the grinding wheel B is fixedly connected to the filter plate B.

[0012] Preferably, the end of the sludge suction pipe communicates with two pipe heads, and the two pipe heads are respectively located at the bottoms of the filter plate A and the filter plate B.

[0013] Preferably, a sludge suction pump is fixedly installed at one end of the bracket. The sludge suction end of the sludge suction pump communicates with a hollow collecting head, and each sludge suction pipe communicates with the collecting head.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] 1. For this automatic drainage device, by setting a double-layer filter plate, the pore sizes of the filter plate A and the filter plate B decrease in sequence. It can not only achieve the purpose of layer-by-layer filtration, reduce the filtration burden, but also generate centrifugal force when the double-layer filter plate rotates, throwing out the sludge adhered to the outside of the filter plate B, preventing sludge from accumulating on the outside of the filter plate B. The sludge suction pipe pumps out the small particle precipitates remaining inside the double-layer filter plate to avoid clogging the filter holes. The bottom ends of the filter plate A and the filter plate B are both in an inverted cone shape, which also increases the contact area with the accumulated water, thereby improving the drainage efficiency.

[0016] 2. For this automatic drainage device, the wrapping shell can be disassembled, which is convenient for taking out the double-layer filter plate from the wrapping shell. Moreover, the double-layer filter plate is also detachable, facilitating subsequent cleaning and maintenance work. By setting one end of the water suction pipe close to the wrapping shell to be made of a rigid material and the other end to be made of a telescopic soft material, by stretching the water suction pipe, it is convenient to extend the distance of the wrapping shell, and then it is convenient to place the wrapping shell in the accumulated water area of the construction site according to requirements.

Specific embodiments

[0024] As Figures 1 - 6 shown, an automatic drainage device includes a fixedly connected support 1 and a water pump 2. The water suction end of the water pump 2 is communicated with a water collector 3. One end of the water collector 3 is in the shape of a hollow sphere, and the other end is in the shape of a cylinder. One end of the water collector 3 is communicated with a plurality of monomer structures 4 for water suction and filtration.

[0025] The monomer structure 4 includes a water suction pipe 401, a wrapping shell 402, a driving component 403, a double-layer filter plate 404 for rotation, and a sludge suction pipe 405 passing through the water suction pipe 401. The double-layer filter plate 404 is used to rotate along the inner wall of the shell 412. The end of the water suction pipe 401 is fixedly connected to the wrapping shell 402. One end of the water suction pipe 401 close to the wrapping shell 402 is made of a hard material, and the other end is made of a telescopic soft material. By stretching the water suction pipe 401, it is convenient to extend the distance of the wrapping shell 402, and then it is convenient to place the wrapping shell 402 into the water accumulation area of the construction site according to requirements. The wrapping shell 402 includes a shell cover 411, a shell body 412, and a threaded cylinder 413. The threaded cylinder 413 is fixedly connected to the shell cover 411, and the shell body 412 is threadedly connected to the threaded cylinder 413, which is convenient for disassembling the shell body 412 from the threaded cylinder 413, and then it is convenient to take out the double-layer filter plate 404 from the wrapping shell 402. The double-layer filter plate 404 includes a filter plate A 406 and a filter plate B 407 stacked together. The bottom ends of the filter plate A 406 and the filter plate B 407 are both in an inverted cone shape, and there is a gap between the two. The end of the sludge suction pipe 405 is communicated with two detachable pipe heads 5. The two pipe heads 5 are respectively located at the bottoms of the filter plate A 406 and the filter plate B 407. The two pipe heads 5 are used to pump out the sediment at the bottoms of the filter plate A 406 and the filter plate B 407. The pore sizes of the filter plate A 406 and the filter plate B 407 decrease in sequence, that is, the pore size of the filter plate B 407 is smaller than that of the filter plate A 406. The upper ends of the filter plate A 406 and the filter plate B 407 are both in a circular ring shape, and the two are fixed by screws, so that the filter plate A 406 and the filter plate B 407 are convenient for disassembly, assembly and fixation. The end of the sludge suction pipe 405 is inserted into the filter plate B 407, and the intersection of the two rotates and slides relative to each other. A notch 408 for water inlet is opened at the bottom end of the shell body 412, and the water level needs to exceed the notch 408. The end of the sludge suction pipe 405 is installed inside the double-layer filter plate 404 for pumping out sediment. The rotation connection is realized by the contact between the inner wall of the filter plate B 407 and the outer surface of one end of the water suction pipe 401. The driving component 403 includes a motor 414 fixed to the shell body 412, a grinding wheel A 415, and an annular grinding wheel B 416. The output rotating shaft of the motor 414 is fixedly connected to the grinding wheel A 415. The grinding wheel A 415 is in close contact with the grinding wheel B 416. The grinding wheel B 416 is fixedly connected to the filter plate B 407. One end of the bracket 1 is fixedly installed with a sludge pump 6. The sludge suction end of the sludge pump 6 is communicated with a hollow collecting head 7. Each sludge suction pipe 405 is communicated with the collecting head 7. The sediment pumped out by the multiple sludge suction pipes 405 gathers in the collecting head 7 and is discharged by the sludge pump 6.

[0026] In use, first place a plurality of wrapping shells 402 at the water accumulation area of the construction site. Since one end of the wrapping shell 402 close to the water suction pipe 401 is made of a hard material and the other end is made of a telescopic soft material, by stretching the water suction pipe 401, it is convenient to extend the distance of the wrapping shell 402, and thus it is convenient to place the wrapping shell 402 in the water accumulation area of the construction site according to requirements. Then, pump out the water accumulation through the water pump 2. At this time, the water accumulation passes through the notch 408, the double-layer filter plate 404, and the water suction pipe 401 in sequence. It should be noted that the drainage end of the water pump 2 needs to be connected to a collection box for accommodating the water accumulation, so as to discharge the water accumulation into the collection box.

[0027] Immediately afterwards, when the water accumulation passes through the notch 408, the water level needs to exceed the notch 408, and large pieces of construction waste are blocked outside the notch 408. When the water accumulation passes through the double-layer filter plate 404, since the pore sizes of the filter plate A 406 and the filter plate B 407 in the double-layer filter plate 404 decrease in sequence, the effect of layer-by-layer filtration is achieved, reducing the filtration burden. Then, drive the grinding wheel A 415 to rotate through the motor 414. The grinding wheel A 415 drives the grinding wheel B 416 to rotate, and the grinding wheel B 416 drives the double-layer filter plate 404 to rotate. The centrifugal force generated during the rotation of the double-layer filter plate 404 throws out the sludge outside the filter plate B 407, preventing the sludge from adhering to the filter holes of the filter plate B 407, and thus preventing the filter holes from being blocked. Moreover, the bottom ends of the filter plate A 406 and the filter plate B 407 are both in an inverted cone shape, which not only makes it easier to throw out the sludge but also increases the contact area with the water accumulation, thereby improving the drainage efficiency.

[0028] Finally, when the water accumulation passes through the filter plate A 406 and the filter plate B 407, some impurities will precipitate to the bottoms of the filter plate A 406 and the filter plate B 407. It should be noted that since the bottom ends of the filter plate A 406 and the filter plate B 407 are both in an inverted cone shape, the precipitates are more likely to gather together. It is necessary to pump out these foreign matters through the sludge pump 6 to avoid blocking the filter holes. When pumping out, these foreign matters pass through the pipe head 5, the sludge suction pipe 405, the collection head 7, and the sludge pump 6 in sequence. The sludge discharge end of the sludge pump 6 needs to be connected to a box for collecting impurities, and the filtered and precipitated foreign matters are discharged through the sludge pump 6.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
