Description

Technical Field

[0001] This utility model relates to the technical field of rainwater collection and drainage facilities, and in particular to a silt-proof rainwater collection well. Background Technology

[0002] Urban drainage systems are engineering facilities for treating and transporting sewage and rainwater. Rainwater is generally collected and discharged into nearby water bodies. To facilitate efficient collection and timely discharge of rainwater, collection wells are installed in urban roads, industrial parks, residential areas, and factory areas. Pipes in the rainwater drainage system are connected through these collection wells to transport and discharge the rainwater collected within them. Currently used collection wells include underground pits, in which pipes for transporting rainwater are pre-buried in the soil on at least two sides. A drain cover is placed at the top of the pit to seal it and ensure its safety. During rainfall, surface rainwater is drawn into the pit for drainage via pipes. However, this system has the following main disadvantages.

[0003] First, the area of ​​the leak cover is small, and the number of leak holes that can be installed is limited. Rainwater can only be collected through the well opening of the pit, so the collection efficiency is low. In addition, the water pressure at the leak cover is relatively high, which can easily cause it to shift and create certain safety hazards.

[0004] Second, during periods of heavy rainfall, the drainage holes on the drain cover are easily blocked by foreign objects such as leaves and plastic bags carried by rainwater, thus affecting the efficiency of rainwater collection and drainage.

[0005] Third, if non-biodegradable foreign objects such as plastic bags are flushed into the pit well, they will be discharged into nearby water bodies through pipes, thus affecting the natural river environment.

[0006] Fourth, surface sand and gravel are carried by rainwater into the pit well, where they easily accumulate at the bottom of the pit well or pipe, making cleaning difficult and inefficient. If not cleaned in time, it will directly affect the normal drainage of the next rainwater. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] Example 1:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-siltation rainwater collection well can collect sand, gravel, lightweight foreign objects, and silt separately, allowing for regular centralized cleaning and maintenance. Cleaning is convenient, labor-saving, and highly efficient. This embodiment specifically includes a well body 1 located below the ground surface. A well cover 2 is provided at the upper end of the well body 1, with upper water collection holes 3 penetrating the well cover 2. A pipe opening 4 for transporting rainwater penetrates the well body 1. A pipe is pre-buried in the soil, sealingly fitting the pipe opening 4. Rainwater is collected and gathered through the well body 1, and the long-distance transport of rainwater is achieved through the cooperation of the pipe opening 4 and the pipe, ultimately discharging it into rivers or other natural water bodies.

[0030] In this embodiment, a water collection trough 5 is provided around the outer side of the upper port of the well body 1. Depending on the location of the well body 1, the water collection trough 5 is arranged in a semi-enclosed or fully enclosed manner around the upper port of the well body 1. If the well body 1 is located in a relatively flat and open area, the water collection trough 5 is arranged in a fully enclosed manner to maximize the volume of the water collection trough 5, thereby maximizing the rainwater collection efficiency. If the well body 1 is located in a location with obstacles nearby, such as a roadside near a green belt, it can be arranged in a semi-enclosed manner, allowing for flexible design and use. The port of the well body 1 is set as rectangular or circular. Specifically, when the port of the well body 1 is set as rectangular, the outer contour of the water collection trough 5 is also relatively straight; when the port of the well body 1 is set as circular, the outer contour of the water collection trough 5 is circular or arc-shaped.

[0031] The outer wall of the well body 1 is radially arranged with water trough partitions 6. Water trough cover plates 7 are supported on adjacent water trough partitions 6. The outer side of the water trough cover plate 7 is limited and supported on the water collection trough 5, and the inner side is limited and supported on the well body 1. The water trough cover plate 7 can be removed from the water trough partitions 6 and the water collection trough 5 for easy cleaning and maintenance of the water collection trough 5. Water holes 8 are provided through the water trough cover plate 7, and side water collection holes 9 are provided through the side wall of the well body 1 between adjacent water trough partitions 6. The water trough partitions 6 divide the water collection trough 5 into sections, allowing the water trough cover plates 7 to seal the water collection trough 5, thus ensuring safety during use. When the port of the well body 1 is rectangular, the water trough cover plate 7 is trapezoidal; when the port of the well body 1 is circular, the water trough cover plate 7 is fan-shaped. The bottom wall of the water collection trough 5 is inclined downwards along the direction of rainwater flow, and the lower end of the water collection trough 5 ends at the side water collection hole 9. This design of the water collection trough 5 allows rainwater entering its interior to quickly flow into the well body 1 through the side water collection hole 9, which helps to improve the rainwater collection efficiency.

[0032] Each of the water tank covers 7 and the water collection tank 5 is equipped with a foreign object interception device. This device primarily intercepts sand and gravel carried by rainwater and prevents them from settling within the water collection tank 5 for centralized cleaning. Specifically, the foreign object interception device includes at least two intercepting filter plates 10 arranged sequentially along the rainwater flow direction within the water collection tank 5. The perforations on the filter plates 10 can be progressively smaller along the rainwater flow direction; that is, the outer filter plates 10 intercept larger sand and gravel, while the inner filter plates 10 intercept smaller sand and gravel. This design creates a tiered interception of sand and gravel, reducing the operating pressure on the filter plates 10 and preventing them from becoming clogged, thus ensuring the effective flow collection function of the water collection tank 5.

[0033] The bottom wall of the water collection tank 5 is provided with filter plate limiting grooves 11 corresponding to each of the intercepting filter plates 10, and the water tank cover plate 7 is provided with filter plate limiting holes 12 corresponding to each of the intercepting filter plates 10. The intercepting filter plates 10 are detachably disposed between the filter plate limiting grooves 11 and the filter plate limiting holes 12, that is, the intercepting filter plates 10 can be removed from the water collection tank 5 to facilitate the cleaning of sand and gravel intercepted in the water collection tank 5. The intercepting filter plates 10 are inclined upwards along the direction of rainwater flow, and when sand and gravel come into contact with the intercepting filter plates 10, they can slide down the intercepting filter plates 10 into the water collection tank 5.

[0034] A cleaning limiting platform 13 is also provided on the inner wall of the well body 1, and the cleaning limiting platform 13 is located below the side water collection hole 9. When it is necessary to clean the water collection tank 5, the water tank cover plate 7 and the intercepting filter plate 10 are removed, and the sand and gravel in the water collection tank 5 can be shoveled out. Alternatively, a container can be placed on the cleaning limiting platform 13, and the sand and gravel can be swept into the container through the side water collection hole 9 for unified removal. The cleaning is convenient and efficient.

[0035] In this embodiment, a foreign object filtering device is provided on the inner wall of the upper port of the well body 1. The foreign object filtering device is mainly used to intercept lightweight foreign objects such as leaves, waste paper, and plastic bags that enter the well body 1 through the upper water collection hole 3 under water pressure. Specifically, the foreign object filtering device includes a foreign object filtering bag 14 and a filtering limiting platform 15 provided on the inner wall of the well body 1. A bag flaring ring 16 is fixedly connected to the port of the foreign object filtering bag 14, and the bag flaring ring 16 is movably supported on the filtering limiting platform 15. The foreign object filtering bag 14 is a soft bag with large and easily deformable filter holes. Although it can extend to the side water collection hole 9, its deformation and large filter hole characteristics do not obstruct the water flow in the side water collection hole 9. Through the cooperation of the bag flaring ring 16 and the filtering limiting platform 15, the foreign object filtering bag 14 is detachably installed in the well body 1. To ensure the stability of each component during use, the well cover 2, the water tank cover 7, and the bag flaring ring 16 can be further secured using pins or bolts.

[0036] like Figure 1 and Figure 4As shown, a sediment collection device is provided at the bottom of the well body 1 for collecting sediment deposited at the bottom of the well. The sediment collection device includes a sediment collection bag 17 and collection hooks 18 installed on the inner wall of the bottom of the well body 1. A bag-closing rope 19 is fitted at the port of the sediment collection bag 17, and part of the bag-closing rope 19 is located outside the sediment collection bag 17 and is detachably hooked to the collection hooks 18. By cooperating with the collection hooks 18, the port of the sediment collection bag 17 is opened to collect sediment. To ensure that the port of the sediment collection bag 17 is arranged as close as possible to the inner wall of the well body 1, the number of collection hooks 18 can be adjusted appropriately. The bag-closing rope 19 can be a slightly elastic rope to facilitate hooking operation.

[0037] In this embodiment, during cleaning, the manhole cover 2 is removed, and the foreign matter filter bag 14 is moved out of the manhole for cleaning. A receiving container is placed on the cleaning limiting platform 13 to collect the sand and gravel cleaned from the water collection tank 5. The receiving container can be equipped with a hanging rope, hook 21, etc., for easy removal, so that it can be placed and removed with the help of the rod and hook. This can also be done at the manhole. The receiving container can be designed with a similar structure to the foreign matter filter bag 14 and the bag body flaring ring 16, but there is no need to make holes in the bag body. The bag body closing rope 19 is separated from the collection fixing hook 18 from the manhole using the rod and hook, and the sediment collection bag 17 can be moved out of the manhole by hooking the bag body closing rope 19. After cleaning, the new foreign matter filter bag 14 is hooked into place from the wellhead using the rod and hook. Then, the foreign matter filter bag 14, the well cover 2, the interception filter plate 10, and the water tank cover 7 are placed in place.

[0038] Example 2:

[0039] like Figure 5 and Figure 6As shown, the difference between this embodiment and Embodiment 1 is the addition of a function for cleaning up debris carried in the transported rainwater, in order to remove large floating objects that accidentally enter the pipe. Specifically, a hook 21 is fixedly installed above the pipe opening 4 on the water outlet side inside the well body 1. A float-blocking plate 20 is detachably hooked onto the hook 21. The float-blocking plate 20 extends through the pipe opening 4 into the corresponding pipe. The float-blocking plate 20 can be a rubber sheet, with high buoyancy and the ability to float on the water surface. Water passage holes 22 are arranged through the float-blocking plate 20. When the transported water volume is large, the float-blocking plate 20 floats on the water surface in the pipe under the action of buoyancy and impact force, and can deform to adapt to the inner cavity of the pipe, so it will not cause pipe blockage or hinder water transport. When the transported water volume is small, its free end may experience varying degrees of downward movement. In this case, the water passage holes 22 can be used to assist in the flow of water, which will also not hinder water transport. One surface of the intercepting floating plate 20 is also provided with intercepting columns 23 for intercepting floating objects in the pipe, which are used to hook foreign objects such as plastic bags and cloth pieces carried in the water. The intercepting columns 23 are also made of plastic columns to avoid excessive weight affecting the floating effect of the intercepting floating plate 20.

[0040] In this embodiment, before cleaning the sediment collection bag 17, the intercepting floating plate 20 can be hooked at the wellhead and pulled out of the well for cleaning. Because the intercepting floating plate 20 has certain deformation characteristics, it can adapt to changes in angle during the lifting process, allowing it to be smoothly pulled out of the pipe and moved to the ground. When it needs to be repositioned after cleaning, it is slowly lowered, using the flow of water to automatically carry it back into the pipe, and finally hooked and fixed onto the hook 21.

[0041] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
