Description

Technical Field

[0001] This utility model relates to the field of engineering drainage technology, and in particular to a drainage anti-clogging device. Background Technology

[0002] High-rise buildings, large underground commercial facilities, and underground transportation hubs require the excavation of foundation pits on the ground before construction. As the depth of the foundation pit increases and the weather affects it, groundwater and rainwater will fill the foundation pit. If this water is not pumped out in time, a softened soil layer will appear on the surface of the foundation pit, which will lead to a deterioration of the foundation strength and a large settlement, endangering the safety of the project construction and the surrounding environment. However, during the pumping process, large mud lumps and other substances often exist in the muddy water. These large mud lumps may block the pumping pipes, thus affecting the quality of the foundation pit drainage work.

[0003] To address the aforementioned issues, existing technology provides an anti-clogging device comprising a mounting base and a filter barrel. The mounting base is connected to the water pump's suction pipe, and the filter barrel is connected to the mounting base. The filter barrel has evenly distributed filter holes on its wall, which can effectively intercept large mud particles.

[0004] However, over time, mud tends to accumulate on the outer wall of the bucket, gradually clogging the filter holes. This significantly increases the resistance to water flow. Furthermore, small mud particles that enter the filter bucket can easily clump together, blocking the filter holes from the inside or clogging the pumping equipment, thus affecting pumping efficiency and preventing normal drainage. This necessitates frequent manual cleaning of the filter holes, increasing labor costs and maintenance workload. Utility Model Content

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-5 As shown, this utility model provides a drainage anti-clogging device, including a support base 1, a filter bucket 2, a drive mechanism 3, a cleaning component 4, and a stirring component 5. The support base 1 is provided with a connecting channel, the filter bucket 2 is provided with a filter chamber, the filter chamber is connected to the connecting channel, and the outer wall of the filter bucket 2 is provided with a plurality of filter holes 20 connected to the filter chamber. The drive mechanism 3 is provided on the support base 1, the cleaning component 4 is provided on the outside of the filter bucket 2, and the stirring component 5 is provided in the filter chamber. The drive mechanism 3 can drive the cleaning component 4 and the stirring component 5 to rotate. When the cleaning component 4 rotates, it can scrape the outer wall of the filter bucket 2.

[0041] This invention features a cleaning component 4 on the outside of the filter bucket 2. When the drive mechanism 3 rotates the cleaning component 4, it scrapes the outer wall of the filter bucket 2, promptly removing mud, sand, and other impurities adhering to the outer wall, preventing the filter holes 20 from becoming clogged, and ensuring that water can flow smoothly through the filter holes 20, maintaining a stable and efficient drainage state. Furthermore, by installing a stirring component 5 inside the filter chamber, when the drive mechanism 3 rotates the stirring component 5, it crushes small particles of mud and other impurities inside the filter chamber, preventing mud from accumulating and blocking the filter holes 20, and avoiding the entry of mud into and clogging the pumping equipment. This improves the quality and efficiency of the foundation pit drainage, allowing the entire drainage process to proceed smoothly and continuously, thereby reducing manual maintenance and lowering maintenance costs.

[0042] In this embodiment, the water pumping pipe 100 extends into the connecting channel and is fixedly connected to the filter bucket 2, so that the water pumping pipe 100 can be stably and reliably connected to the filter chamber, and the water filtered by the filter bucket 2 can flow to the water pumping pipe in an orderly manner, avoiding water flow disturbance or leakage.

[0043] In this embodiment, a flange is provided at one end of the water pumping pipe 100, and a flange is also provided at the corresponding position on the filter bucket 2. Six threaded holes are evenly distributed on the two flanges. During installation, the threaded holes of the two flanges are aligned, and then bolts are inserted for tightening.

[0044] Specifically, such as Figure 2 As shown, the drive mechanism 3 includes a drive motor 31, a driving wheel 32, and a driven wheel 33. The drive motor 31 is mounted on the support base 1, the driving wheel 32 is connected to the output end of the drive motor 31, and the driven wheel 33 is rotatably mounted on the support base 1 and is driven by the driving wheel 32. The cleaning component 4 is connected to the driven wheel 33. The drive mechanism 3, through the combination of the drive motor 31, the driving wheel 32, and the driven wheel 33, achieves efficient power transmission, ensuring the stable operation of the cleaning component 4. Furthermore, the rotation speed can be flexibly adjusted according to actual needs, precisely controlling the cleaning action and effectively cleaning different degrees of blockage. In addition, the drive mechanism 3 has a clear structure, facilitating maintenance and component replacement.

[0045] More specifically, such as Figures 2-3 As shown, the driving wheel 32 and the driven wheel 33 are meshed together, which has a compact structure and high reliability, and can ensure the continuity and stability of power transmission, so that the drive cleaning component 4 can work continuously and stably.

[0046] In other embodiments, the driving wheel 32 and the driven wheel 33 may also abut against each other, transmitting power through friction. In other embodiments, the driving wheel 32 and the driven wheel 33 may also transmit power through a drive belt.

[0047] Specifically, such as Figures 3-4 As shown, the drive mechanism 3 also includes a slider 34. The support base 1 is provided with an annular groove 10, and the slider 34 is slidably disposed in the annular groove 10. The driven wheel 33 is connected to the slider 34. The slider 34 can constrain the driven wheel 33 to move stably along the annular groove 10, so that the driven wheel 33 will not easily wobble or shake when rotating, ensuring the accuracy and stability of the meshing between the driven wheel 33 and the driving wheel 32. In this way, the scraping range of the cleaning component 4 on the outer wall of the filter barrel 2 can be precisely controlled, thereby improving the cleaning quality.

[0048] More specifically, multiple sliders 34 are provided, and the multiple sliders 34 are evenly arranged circumferentially within the annular groove 10. The evenly distributed multiple sliders 34 can further constrain the driven wheel 33, prevent the driven wheel 33 from deviating during rotation, and ensure that the driven wheel 33 rotates strictly along the annular path defined by the annular groove 10. Furthermore, the action of the cleaning component 4 in scraping the outer wall of the filter barrel 2 is also more stable when it rotates with the driven wheel 33.

[0049] In this embodiment, the cross-section of the annular groove 10 is T-shaped. The T-shape, which is wider at the top and narrower at the bottom, can prevent the slider 34 from coming out of the annular groove 10 in the vertical direction, thereby ensuring the stability of the driven wheel 33's rotation.

[0050] In this embodiment, four sliders 34 are provided, and the four sliders 34 are evenly arranged in the annular groove 10.

[0051] In other embodiments, the number of sliders 34 can be flexibly adjusted according to factors such as the mass and size of the driven wheel 33 and the common operating conditions of the device as a whole. For example, when facing a driven wheel 33 with a large mass and a relatively large size, in order to ensure that it rotates stably and smoothly in the annular groove 10, six sliders 34 can be set. The six sliders 34 are evenly distributed in the annular groove 10 to provide balanced and sufficient support force for the driven wheel 33.

[0052] Specifically, such as Figures 3-4 As shown, the outer wall of the filter bucket 2 includes a side wall 21 and a bottom wall 22. Multiple filter holes 20 are respectively provided on the side wall 21 and the bottom wall 22. The cleaning assembly 4 includes a first cleaning component 41 and a second cleaning component 42 connected to each other. When the cleaning assembly 4 rotates, the first cleaning component 41 scrapes the side wall 21, and the second cleaning component 42 scrapes the bottom wall 22. In actual foundation pit drainage processes, impurities such as mud and sand not only adhere to the side wall 21 but also easily accumulate on the bottom wall 22. By providing multiple filter holes 20 on the side wall 21 and the bottom wall 22, and equipping them with corresponding first and second cleaning components 41 and 42, effective cleaning of the outer wall of the filter bucket 2 from all directions can be achieved, ensuring that water can flow smoothly through the filter holes 20 in each part, thereby maintaining high drainage efficiency.

[0053] In this embodiment, multiple filter holes 20 are evenly arranged at equal intervals in the circumferential and height directions of the side wall 21 of the bucket. Multiple filter holes 20 are arranged radially from the center of the bottom wall 22 of the bucket towards the edge. The filter holes 20 of the side wall 21 and the filter holes 20 of the bottom wall 22 of the bucket are the same in shape and size. The water pumping pipe 100 is fixedly connected to the end of the side wall 21 of the bucket away from the bottom wall 22.

[0054] In other embodiments, the arrangement of the filter holes 20 can be flexibly adjusted according to the actual situation. For example, if the water contains a large number of impurities, including large stones, branches and mud, the filter holes 20 need to be set in a combination of different sizes. Larger filter holes 20 are set on the part of the side wall 21 near the water inlet to intercept large impurities; smaller filter holes 20 are set on other parts of the side wall 21 and the bottom wall 22 of the bucket to filter fine impurities.

[0055] More specifically, the first cleaning component 41 includes two scrapers 411 located on opposite sides of the filter barrel 2. The second cleaning component 42 is connected at one end to one of the scrapers 411 and at the other end to the other scraper 411. This symmetrical cleaning method ensures a wider cleaning coverage of the barrel sidewall 21 during a single rotation. Furthermore, the two scrapers 411 can balance the lateral forces generated on the filter barrel 2 during cleaning, preventing the filter barrel 2 from shaking or shifting due to uneven scraping force on one side, thereby ensuring the stability of the filter barrel 2 during operation. Furthermore, the second cleaning component 42 is connected at one end to one of the scrapers 411 and at the other end to another scraper 411, forming a cleaning structure that spans the bottom wall 22 of the barrel. When the cleaning component 4 rotates, the second cleaning component 42 can perform comprehensive scraping and cleaning of the entire bottom wall 22 of the barrel along the rotation trajectory, preventing the accumulation of material from clogging the filter holes 20 on the bottom wall 22 of the barrel, ensuring the smooth drainage of the bottom wall 22 of the barrel, and improving the drainage efficiency and anti-clogging effect of the entire filter barrel 2.

[0056] In other embodiments, the first cleaning component 41 may also include three, four or more scrapers 411. For example, the first cleaning component 41 includes four scrapers 411, which are evenly distributed around the filter barrel 2. The second cleaning component 42 is a cross scraper, and the four scrapers 411 correspond one-to-one with the four ends of the second cleaning component 42 and are connected to each other, which can complete the cleaning task of the outer wall of the filter barrel 2 more quickly and efficiently.

[0057] In this embodiment, the scraper 411 is trapezoidal with a wider bottom, which provides better stability during installation and rotation. When cleaning the side wall of the bucket, as the scraper rotates, dirt and other impurities can be guided by the inclined edge of the scraper and gradually slide down towards the bottom of the bucket, effectively removing impurities.

[0058] More specifically, such as Figure 3 As shown, the cleaning assembly 4 also includes a connecting rod 43, which is connected to the driven wheel 33. The first cleaning component 41 is detachably connected to the connecting rod 43. After working for a period of time, the first cleaning component 41 is prone to severe wear or deformation due to accidental impact. In this case, maintenance personnel do not need to disassemble the entire device on a large scale. They only need to remove the first cleaning component 41 from the connecting rod 43 and replace it with a new one, which reduces the difficulty of maintenance and shortens the maintenance time.

[0059] In this embodiment, the connecting rod 43 is an L-shaped rod, and there are two of them. The two scrapers 411 and the two connecting rods 43 correspond to each other and are connected.

[0060] In other embodiments, the connecting rod 43 may also be a straight rod, and the number of connecting rods 43 may be set according to the number of scrapers 411. For example, when there are four scrapers 411, there are also four connecting rods 43.

[0061] In this embodiment, the scraper 411 and the connecting rod 43 are connected by bolts. During installation, simply align the threaded hole on the scraper 411 with the corresponding hole on the connecting rod 43, and then tighten the bolts to complete the connection. This connection method is simple, direct, and highly stable.

[0062] In other embodiments, the scraper 411 and the connecting rod 43 can also be connected by a snap fastener. The scraper 411 is provided with an elastic snap fastener, and the connecting rod 43 is provided with a corresponding slot. During installation, the snap fastener is aligned with the slot and a certain pressure is applied so that the snap fastener undergoes elastic deformation and is embedded in the slot. When the snap fastener returns to its original state, the scraper 411 and the connecting rod 43 are firmly connected together.

[0063] Specifically, the stirring component 5 includes a stirring shaft 51 and a stirring paddle 52. The stirring shaft 51 is connected to the cleaning assembly 4, and the stirring paddle 52 is mounted on the stirring shaft 51. When the cleaning assembly 4 rotates, the stirring shaft 51 connected to it can synchronously obtain rotational power, thereby driving the stirring paddle 52 mounted on it to rotate, realizing the stirring function of the material in the filter chamber. This simplifies the power system structure of the entire drainage anti-clogging device, reduces costs and the complexity of the device.

[0064] More specifically, multiple agitators 52 are provided, and these agitators 52 are evenly arranged along the length of the agitator shaft 51. When the agitator shaft 51 rotates, the agitators 52 can function simultaneously at different longitudinal positions in the filter chamber. Regardless of the height of the mud-water mixture in the filter chamber, it can be affected by the agitation of the agitators 52, achieving all-round coverage of the entire filter chamber space from bottom to top. This ensures that impurities in the filter chamber are evenly dispersed and stirred, maintaining good fluidity and preventing the filter holes 20 from becoming clogged due to local sedimentation and accumulation.

[0065] In this embodiment, the stirring shaft 51 is connected to the second cleaning component 42 and extends into the filter chamber from the center of the bottom wall 22 of the barrel. When the second cleaning component 42 rotates, the stirring shaft 51 can rotate around itself, so that the overall center of gravity of the device changes relatively little, reducing the shaking and vibration of the device caused by the movement of the stirring shaft 51, improving the structural stability of the entire device, reducing the risk of component wear and failure due to structural instability, and extending the service life of the device.

[0066] In other embodiments, the bottom wall 22 of the barrel is provided with an annular groove, the stirring shaft 51 is connected to the second cleaning member 42 and extends into the filter chamber from the annular groove. When the second cleaning member 42 rotates, the stirring shaft 51 can rotate along the annular groove, and its stirring range can cover a larger area in the filter chamber, thereby more comprehensively stirring the impurities in the filter chamber.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
