Description

Technical Field

[0001] This utility model relates to the field of road drainage diversion technology, specifically a diversion device. Background Technology

[0002] Urban roads and transportation are both municipal infrastructure, referring to construction projects set up within the planning and construction scope of urban areas, towns, and villages to provide paid or free public goods and services to residents based on the government's responsibility and obligation. During the construction of urban roads and transportation, sewer diversion devices are often used to divert rainwater from the roads. Currently, the commonly used diversion device on urban roads is the sewer pipe, which is then covered with a manhole cover, and the water flows into the sewer pipe through the holes in the manhole cover.

[0003] The existing patent publication number CN221399264U discloses a flow guiding device. When cleaning is required, the manhole cover is opened and removed. The pressure plate loses the pressure of the flow guiding bucket, and the spring rebounds, allowing the guide column to slide upward. The guide column drives the limiting plate to move upward. The limiting plate pulls the T-shaped cylindrical pin inward through the hinge strip, thereby disengaging the T-shaped cylindrical pin from the annular groove. Then, the filter plate can be removed for cleaning. This effectively filters impurities in rainwater, preventing impurities from flowing into the pipe, preventing pipe blockage, and making cleaning more convenient and improving practicality.

[0004] In the aforementioned patent, the filter plate is horizontally arranged in a disc shape. Water flows onto the filter plate to filter impurities. When the water is dirty or not cleaned in time, too much garbage and impurities will accumulate on the filter plate, which will affect the water permeability of the filter plate and the filtration flow rate of the water, making it unsuitable for use. In addition, it is fixed with components such as T-shaped cylindrical pins, and its fixing structure is relatively complex. Moreover, cleaning the garbage requires complete disassembly and removal, which is not convenient. Utility Model Content

[0005] The purpose of this utility model is to provide a flow guiding device to solve the problems mentioned in the background art, which are that when the water is dirty or not cleaned in time, too much garbage and impurities will accumulate on the filter plate, which will affect the water permeability of the filter plate, affect the filtration flow of the water, and make it unsuitable for use. At the same time, the device is fixed with T-shaped cylindrical pins and other components, which makes its structure more complicated and not conducive to later maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow guiding device, comprising a drainage well and a manhole cover fitted onto the top of the drainage well. A support ring is fixedly installed on the lower inner side of the drainage well, and a flow guiding and filtering assembly located below the manhole cover is movably engaged at the top of the support ring. The flow guiding and filtering assembly includes a support ring plate fitted onto the top of the support ring. The support ring plate has a first water inlet and two water inlets located on the left and right sides of the first water inlet. Stepped grooves are provided on the inner sides of both the first and second water inlets. A guide filter plate is movably engaged inside the first water inlet. Filter holes are equidistantly arranged inside the guide filter plate. A collection frame is movably engaged inside the second water inlet. The guide filter plate is arranged in an inverted "V" shape, and filter holes are equidistantly arranged at the bottom of the collection frame.

[0007] Preferably, the collection frame is symmetrically arranged on the left and right sides of the guide filter plate, and a centrally located lifting rod is fixedly connected to the top of the collection frame.

[0008] Preferably, the outer side of the collection frame is arc-shaped, and the length of the collection frame is greater than that of the adaptive guide filter plate.

[0009] Preferably, the lowermost ends of the left and right sides of the guide filter plate are flush with the support ring plate.

[0010] Preferably, lifting plates are fixedly connected to both the front and rear sides of the top of the support ring plate, and a locking block is movably engaged on the inner side of the lifting plate. A flow guide hood located above the guide filter plate is fixedly connected to the top of the locking block. The top of the flow guide hood is attached to the bottom of the well cover, and the flow guide hood is designed to contract downwards.

[0011] Preferably, a handle is fixedly connected to the outer side of the lifting plate, and a buckle groove is provided on the outer side of the locking block.

[0012] Preferably, the bottom of the support ring plate is fixedly connected with a ring of equally spaced limiting posts, and the inside of the support ring is provided with limiting holes corresponding to the limiting posts, and the limiting posts are movably engaged inside the limiting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Water flows onto the guide filter plate and enters the drainage well through filter hole one, while garbage is intercepted by the guide filter plate and flows with the water to both sides, eventually falling into the collection box. In the collection box, garbage and impurities are centrally processed, and the remaining water enters the drainage well through filter hole two, thereby preventing impurities from accumulating on the guide filter plate, ensuring unobstructed water permeability, increasing garbage filtration capacity, extending the cleaning cycle, and reducing the amount of cleaning work.

[0015] 2. Open the manhole cover, pull the buckle to make the guide cover and the clamp slide upward along the lifting plate and disassemble, revealing the guide filter plate and the collection frame. Then operate the lifting rod to lift the collection frame upward along the second water inlet, which is convenient for dumping and cleaning of garbage. At the same time, if necessary, the guide filter plate can also be removed from the first water inlet for cleaning, improving the efficiency of maintenance and cleaning. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a flow guiding device, including a drainage well 1 and a manhole cover 2 fixedly mounted on the top of the drainage well 1. A support ring 3 is fixedly installed on the lower inner side of the drainage well 1. The top of the support ring 3 is movably engaged with a flow guiding and filtering assembly 4 located below the manhole cover 2. The flow guiding and filtering assembly 4 includes a support ring plate 41, which is fixedly mounted on the top of the support ring 3. The support ring plate 41 has a first water inlet 42 and two water inlets 43 located on the left and right sides of the first water inlet 42. The inner sides of both the first water inlet 42 and the second water inlet 43 are provided with stepped grooves 44. A guide filter plate 45 is movably engaged inside the first water inlet 42. The guide filter plate 45 has an inner... The filter has equidistant filter holes 46, and a collection frame 47 is movably connected inside the water inlet 43. The guide filter plate 45 is arranged in an inverted "V" shape. The bottom of the collection frame 47 has equidistant filter holes 48. Water flows onto the guide filter plate 45 and enters the drainage well 1 through the filter holes 46. The garbage is intercepted by the guide filter plate 45 and flows to both sides with the water, eventually falling into the collection frame 47. In the collection frame 47, the garbage and impurities are centrally processed, and the remaining water enters the drainage well 1 through the filter holes 48. This prevents impurities from accumulating on the guide filter plate 45, ensures unobstructed water permeability, increases garbage filtration capacity, extends the cleaning cycle, and reduces the amount of cleaning work.

[0024] The collection frame 47 is symmetrically arranged on the left and right sides of the guide filter plate 45. The top of the collection frame 47 is fixedly connected to the centrally located lifting rod 49. The outer surface of the lifting rod 49 is provided with anti-slip texture, which makes it easy for operators to grip firmly during cleaning or maintenance. The collection frame 47, which is symmetrically arranged on both sides of the guide filter plate 45, fully adapts to the inverted "V" shape of the guide filter plate 45, ensuring stable collection of waste.

[0025] The outer side of the collection frame 47 is arc-shaped. The length of the collection frame 47 is greater than that of the matching guide filter plate 45. The arc-shaped outer side design of the collection frame 47 can make full use of the space, increase the internal capacity, and thus increase the amount of garbage collected. At the same time, it can also reduce dead corner residue during cleaning, making operation more convenient, reducing maintenance frequency, and improving practicality.

[0026] The bottom ends of the left and right sides of the guide filter plate 45 are flush with the support ring plate 41, which can ensure the stability of the guide filter plate 45 in the overall structure, avoid the problem of garbage residue or water flow obstruction caused by height difference, and allow garbage to fall smoothly into the collection box 47, reducing the risk of blockage caused by local water accumulation.

[0027] Please see Figure 3 and Figure 4Lifting plates 410 are fixedly connected to the front and rear sides of the top of the support ring plate 41. A locking block 411 is movably engaged on the inner side of the lifting plate 410. A flow guide hood 412 located above the guide filter plate 45 is fixedly connected to the top of the locking block 411. The top of the flow guide hood 412 fits against the bottom of the well cover 2. The flow guide hood 412 is designed to contract downwards. The downward contraction design of the flow guide hood 412 can effectively guide the water flow to the guide filter plate 45, thereby improving drainage efficiency. The connection between the lifting plate 410 and the flow guide hood 412 through the locking block 411 makes the entire structure more flexible and convenient to install and disassemble, facilitating subsequent maintenance and replacement work.

[0028] A handle 413 is fixedly connected to the outside of the lifting plate 410, and a latching groove 414 is opened on the outside of the locking block 411. When the manhole cover 2 is opened, the latching groove 414 is pulled to make the guide cover 412 and the locking block 411 slide upward along the lifting plate 410 and disassemble, exposing the guide filter plate 45 and the collection frame 47. Then, the lifting rod 49 is operated to lift the collection frame 47 upward along the second water inlet 43, which facilitates the dumping and cleaning of garbage. At the same time, if necessary, the guide filter plate 45 can also be removed from the first water inlet 42 for cleaning, improving the efficiency of maintenance and cleaning.

[0029] Please see Figure 5 The bottom of the support ring plate 41 is fixedly connected with a ring of equally spaced limiting posts 415. The inside of the support ring 3 is provided with limiting holes 31 corresponding to the limiting posts 415. The limiting posts 415 are movably engaged inside the limiting holes 31. The cooperation between the limiting posts 415 and the limiting holes 31 can ensure the stable connection of the support ring plate 41 on the support ring 3, facilitate installation and disassembly, and effectively prevent the support ring plate 41 from shifting during use, thus ensuring the stability and reliability of the entire device.

[0030] Working principle: The support ring plate 41 is inserted into the limiting hole 31 by the limiting post 415 at the bottom of the support ring 3, and the support ring 3 supports the support ring plate 41. Then, the guide filter plate 45 is inserted into the inside of the first water inlet 42, and the collection frame 47 is inserted into the second water inlet 43 on the left and right sides of the guide filter plate 45 respectively. Then, the flow guide cover 412 is inserted into the inside of the lifting plate 410 by the side locking block 411. Finally, the well cover 2 is installed on the drainage well 1.

[0031] Water flows into the drainage well 1 through the manhole cover 2. The water is collected by the guide hood 412 and then flows onto the guide filter plate 45. The guide filter plate 45, which is inverted in a "V" shape, receives the water. The water flows into the interior of the drainage well 1 through the filter hole 46. Impurities are blocked by the guide filter plate 45 and are washed along the sides of the guide filter plate 45 by the water flow. They move towards the collection frame 47 and then fall into the interior of the collection frame 47. The garbage and impurities are collected inside the collection frame 47. The residual water flows into the drainage well 1 through the filter hole 48. This prevents impurities from accumulating too much on the guide filter plate 45, ensuring the water permeability of the filter hole 46 and preventing clogging, extending the cleaning cycle and reducing the cleaning intensity.

[0032] During cleaning, the manhole cover 2 is opened, and the locking groove 414 is engaged to allow the guide shield 412 and the locking block 411 to slide upwards from the lifting plate 410, exposing the guide filter plate 45 and the collection frame 47. Then, the lifting rod 49 is pulled to move the collection frame 47 upwards along the second permeable outlet 43 to remove the collection frame 47 from the second permeable outlet 43, facilitating the dumping and cleaning of waste. Simultaneously, the guide filter plate 45 can be removed from the first permeable outlet 42 for cleaning, thereby improving the convenience of maintenance and cleaning. The above describes the entire working process of the device. Any content not described in detail in this specification belongs to existing technology known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
