[0029] In the process of underground water resource collection, water often contains a large amount of silt and other impurities.

And some devices with sand removal function have the problems of complex structure, large volume, high cost and are not convenient for wide application. In addition, most of the traditional devices are ground type, which occupies a large area, affects the surrounding environment and is easily disturbed by external factors.

[0030] As shown in Figures 1 to 4 A gravity settling and filter screen based underground buried water collecting and sand removing device, comprising a water collecting well 1, a water collecting pool 2, a settling cylinder 3 and a water pumping mechanism 4. The water collecting well 1 is opened in the ground, and the inner wall of the water collecting well 1 protrudes a support plate 11; the water collecting pool 2 is located below the water collecting well 1 and can collect treated water source; the settling cylinder 3 is located in the water collecting well 1 and above the support plate 11, the bottom of the settling cylinder 3 protrudes a settling ring 31 upward, the settling ring 31 and the side wall of the settling cylinder 3 form a settling area 32, and a conical filter screen 33 is arranged above the settling ring 31, which can filter the overflow water in the settling area 32 to the water collecting pool 2; the water pumping mechanism 4 comprises a water pump 41 and a water pumping pipe 42 connected with the water pump 41, and the water pump 41 pumps the water source in the water collecting pool 2 to the ground through the water pumping pipe 42.

[0031] Through the cooperation of gravity settling and filter screen, the silt and other impurities in the water flow first settle in the settling area 32 after entering the settling cylinder 3, the remaining water is further filtered through the conical filter screen 33, and finally enters the water collecting pool 2. The water pumping mechanism 4 pumps the filtered water source to the ground. This design effectively solves the problem of too much silt and impurities in the process of underground water resource collection, and has the advantages of simple structure, low cost and wide application.

[0032] Compared with the prior art, the device has the advantages of simple structure, low cost and wide application. The existing water collecting device often cannot effectively remove silt, or has a complex structure, a large size and high cost. The device can efficiently remove silt and ensure water quality through the synergistic effect of gravity settling and filter screen.

[0033] The device effectively solves the problem of excessive silt in the process of collecting groundwater resources through the synergistic effect of the water collecting well 1, the water collecting pool 2, the settling cylinder 3, the conical filter screen 33 and the water pumping mechanism 4. The water collecting well 1 is provided below the ground to provide the basic structure and support of the device. The water collecting pool 2 is located below the water collecting well 1 and is used to collect the treated water source. The settling cylinder 3 is located inside the water collecting well 1 and above the support plate 11, and the bottom of the settling cylinder 3 protrudes upward to form a settling area 32 with a settling ring 31, which is used to preliminarily settle silt. The conical filter screen 33 is located above the settling ring 31 and is used to further filter the accumulated water overflowing from the settling area 32. The water pumping mechanism 4 includes a water pump 41 and a water pumping pipe 42 and is used to pump the water in the water collecting pool 2 to the ground. Through the synergistic effect of these features, the silt and other impurities in the water flow first settle in the settling area 32 after entering the settling cylinder 3, the water on the surface of the settling area 32 is further filtered through the conical filter screen 33, and finally enters the water collecting pool 2. The water pumping mechanism 4 pumps the filtered water to the ground. This design effectively solves the problem of excessive silt in the process of collecting groundwater resources, and has the advantages of simple structure, low cost and wide application.

[0034] Preferably, a conical water baffle 34 is fixed above the conical filter screen 33, and the maximum diameter of the conical water baffle 34 is greater than that of the conical filter screen 33, so as to prevent the water flowing into the water collecting well 1 from impacting the conical filter screen 33 and causing damage to the conical filter screen 33, and to prevent the accumulated water containing silt from being directly filtered through the conical filter screen 33 without settling.

[0035] In an embodiment, a conical water baffle 34 is fixed above the conical filter screen 33, and the maximum diameter of the conical water baffle 34 is greater than that of the conical filter screen 33. The conical water baffle 34 can block the water flowing into the water collecting well 1 from directly impacting the conical filter screen 33, prevent the accumulated water containing silt from being directly filtered through the conical filter screen 33 without settling, ensure that the accumulated water in the settling cylinder 3 can be fully settled, and thus improve the filtering quality. The conical water baffle 34 can also divert the accumulated water such as rainwater directly falling into the water collecting well 1, so as to avoid the impact damage of the water flow to the conical filter screen 33.

[0036] The conical water baffle 34 can be made of various materials such as stainless steel, plastic, or synthetic materials to improve its durability and corrosion resistance. The conical water baffle 34 can be fixed by welding, bolting, or bonding to ensure its stability. The shape and size of the conical water baffle 34 can be adjusted according to the specific application requirements to adapt to different catch basins 1 and conical screens 33. In addition, the surface of the conical water baffle 34 can be smoothed or textured to reduce water flow resistance and increase the flow distribution effect.

[0037] The present application can effectively block and distribute water flow by setting the conical water baffle 34 above the conical screen 33, avoiding direct impact of water flow on the conical screen 33, thereby improving the filtering effect and prolonging the service life of the screen. At the same time, the setting of the conical water baffle 34 also helps to ensure that the accumulated water in the settling cylinder 3 can be fully settled, further improving the filtering quality. Compared with the prior art, the design of the present application is simple in structure and low in cost, and is easy to be widely applied.

[0038] Preferably, a steel structure skeleton is arranged in the conical screen 33, which supports the conical water baffle 34.

[0039] In an embodiment, the steel structure skeleton plays a key role in solving the stability and support problems of the conical screen 33. It provides the necessary structural support to ensure that the conical screen 33 and the conical water baffle 34 do not deform or collapse during use, thereby improving the overall stability and reliability of the device. Through this design scheme, the stability and support problems that the conical screen 33 may encounter in actual application are solved, ensuring the effective operation of the device.

[0040] Specifically, the steel structure skeleton can be implemented in various ways, for example, it can be a mesh skeleton structure formed by welding a ring-shaped steel ring with longitudinal steel bars to enhance the overall strength and stability.

[0041] Therefore, the present application solves the stability and support problems of the conical screen 33 and the conical water baffle 34 by arranging a steel structure skeleton in the conical screen 33. Compared with the prior art, this design scheme not only improves the overall stability and reliability of the device, but also avoids the deformation or collapse problems that may occur during use, ensuring the effective operation of the device.

[0042] Preferably, the top of the settling ring 31 is provided with a conical gathering plate 35, and the conical screen 33 is fixed above the conical gathering plate 35. In the vertically downward direction, the outer diameters of the conical screen 33 and the conical gathering plate 35 gradually increase, and the maximum outer diameter of the conical screen 33 is equal to the minimum outer diameter of the conical gathering plate 35.

[0043] In an embodiment, the top of the settling ring 31 is provided with a tapered converging plate 35 that guides the water flow before it enters the tapered filter screen 33. The tapered filter screen 33 is arranged above the tapered converging plate 35 and its outer diameter gradually increases in a vertically downward direction, which allows the water flow to pass through the filter screen stably and facilitates the settling of the sediment. The maximum outer diameter of the tapered filter screen 33 is equal to the minimum outer diameter of the tapered converging plate 35, which ensures the guiding effect of the water flow and the filtering effect.

[0044] The tapered converging plate 35 can be made of stainless steel or other corrosion-resistant materials to ensure its durability in long-term use. The tapered filter screen 33 can be selected with different pore sizes according to different water quality and sediment content. The connection between the tapered filter screen 33 and the tapered converging plate 35 can be achieved by welding or bolting, etc., to ensure the stability and sealing of the structure.

[0045] The present application sets the tapered converging plate 35 on the top of the settling ring 31 and arranges the tapered filter screen 33 above it, which guides the water flow before it enters the filter screen and facilitates the collection of the settled sediment, reduces the water capacity of the settling cylinder 3, and reduces the load pressure on the support plate 11. Compared with the prior art, the present application has a simple structure, is easy to manufacture and install, and improves the sedimentation and filtration efficiency of the sediment in the water.

[0046] Preferably, the tapered filter screen 33 has multiple pore size types.

[0047] In an embodiment, the technical feature of the present application is that the tapered filter screen 33 has multiple pore size types. By designing filter screens with different pore sizes, different particle sizes of sediment can be effectively filtered out, thereby improving the filtering effect. The filter screen with multiple pore size types can separate and filter the sediment at different levels, ensuring the cleanliness of the water source. This design allows the device to adapt to different water quality conditions, providing higher filtration efficiency and a wider range of applications.

[0048] The multiple pore size types of the tapered filter screen 33 can be achieved by different designs. For example, different sizes of pore diameters can be arranged in different areas of the tapered filter screen 33, so that when the water flow passes through the filter screen, larger sediment particles are filtered out first, and then smaller sediment particles are gradually filtered out. In addition, a multi-layer structure filter screen can be used, with the pore diameter of each layer gradually decreasing, thereby achieving the effect of graded filtration. The material of the filter screen can also be selected as different metals or non-metallic materials according to the needs, to improve its corrosion resistance and service life.

[0049] By adopting multiple aperture types of conical filter screens 33, the application can effectively solve the problem of filtering different particle sizes of sediment. Compared with the prior art, the design of the application can more efficiently remove sediment in water, improve the cleanliness of water sources, adapt to different water quality conditions, provide higher filtering efficiency and a wider range of applications. Thus, the application significantly improves the sand removal effect while being simple in structure, moderate in cost and easy to be widely applied.

[0050] Preferably, the top of the settling cylinder 3 is provided with a support ring plate 36, which is horizontally arranged and fixed to the outer wall of the settling cylinder 3, and abuts to the top of the water collecting well 1, so that the settling cylinder 3 can be stably fixed to the upper position of the water collecting well 1.

[0051] In an embodiment, the technical scheme includes arranging a support ring plate 36 at the top of the settling cylinder 3 and horizontally fixing it on the outer wall of the settling cylinder 3, so that the support ring plate 36 can abut to the top of the water collecting well 1. The support ring plate 36 provides additional support and stability, ensuring that the settling cylinder 3 does not displace or tilt in the water collecting well 1 due to water flow or other external factors, thereby improving the stability and reliability of the entire device. By adding a support ring plate 36 at the top of the settling cylinder 3, the stability of the settling cylinder 3 in the water collecting well 1 can be effectively solved, ensuring that the device can maintain stability during operation and avoid affecting the sand removal effect due to displacement of the settling cylinder 3.

[0052] Specifically, the support ring plate 36 can be made of steel, stainless steel or other materials with high strength and corrosion resistance to ensure its reliability during long-term use. The size and shape of the support ring plate 36 can be customized according to the specific dimensions of the settling cylinder 3 and the water collecting well 1 to ensure that it can fit tightly and provide sufficient support. Further, the support ring plate 36 can be fixed firmly on the outer wall of the settling cylinder 3 by welding, bolting or other appropriate connection methods to ensure that it does not loosen or fall off when subjected to external forces.

[0053] Thus, by arranging a support ring plate 36 at the top of the settling cylinder 3, the application enhances the stability of the settling cylinder 3 in the water collecting well 1, avoiding the problem of displacement or tilting of the settling cylinder 3 due to external forces. Compared with the prior art, the technical scheme of the application is simple in structure, easy to implement, and can effectively improve the operational stability and reliability of the water collecting and sand removing device.

[0054] Preferably, a well cover 37 is arranged and fixed above the settling cylinder 3, and a plurality of water discharge holes 371 are formed in the well cover 37.

[0055] In one embodiment, the problem of preventing debris from entering during installation and operation of the underground buried water collecting and desanding device is solved by laying a well cover 37 above the settling cylinder 3 and opening drainage holes 371, while ensuring normal water inflow and maintaining the normal working state of the device. The fixed well cover 37 above the settling cylinder 3 is used to protect the internal structure and prevent large debris or foreign matter from entering, thereby ensuring the normal operation of the device. The several drainage holes 371 on the well cover 37 ensure the normal inflow of water and do not affect the water collecting function of the device.

[0056] The well cover 37 can be made of corrosion-resistant materials to ensure its long service life in the underground environment. The size and distribution of the drainage holes 371 can be designed according to actual needs to balance the water flow and prevent debris from entering. For example, the drainage holes 371 can adopt a mesh structure to further improve the filtering effect. The fixing method of the well cover 37 can adopt bolt fixing or buckle fixing to ensure that it does not loosen or shift during operation.

[0057] Preferably, the water collecting and desanding device further comprises a water diversion channel 5 dug in the ground, which is connected to the settling cylinder 3 to improve the water collecting efficiency of the water collecting and desanding device.

[0058] In one embodiment, the connection design of the water diversion channel 5 and the settling cylinder 3 can guide surface water into the settling cylinder 3, effectively removing the sediment in the water through the synergistic effect of gravity settling and filter screen. By setting the water diversion channel 5, surface water is introduced into the settling cylinder 3, realizing effective guidance and control of water flow, and solving the problem that existing water collecting devices cannot effectively remove sediment.

[0059] Further, the water diversion channel 5 can adopt various materials and structural forms, such as concrete, masonry or other durable materials, to ensure that it can stably guide water flow for a long time. The cross-sectional shape of the water diversion channel 5 can be rectangular, trapezoidal or other suitable shapes to adapt to different terrains and water flow conditions. A grid or coarse filter screen can be provided at the inlet of the water diversion channel 5 to block larger debris from entering the settling cylinder 3 and prevent clogging.

[0060] By setting the water diversion channel 5, surface water can be effectively guided into the settling cylinder 3, and the sediment in the water can be effectively removed by the dual action of gravity settling and filter screen in the settling cylinder 3. Compared with the prior art, the design of the present application not only has simple structure and low cost, but also can significantly improve the desanding effect, is suitable for water collecting and desanding needs in various environments, and has high practical value.

[0061] Preferably, the support plate 11 is provided with a plurality of support plates 11 uniformly distributed along the circumferential direction of the water collecting well 1, and each support plate 11 is at the same horizontal height, improving the stability of the fixing of the settling cylinder 3.

[0062] In an embodiment, the technical features of the present application include that the support plates 11 are provided in multiple numbers and uniformly distributed along the circumferential direction of the water collecting well 1, and each support plate 11 is at the same horizontal height. Through the uniform distribution and the same horizontal height design, the stability of the settling cylinder 3 in the water collecting well 1 is ensured, and the settling cylinder 3 is not prone to tilting or moving, thereby improving the reliability and service life of the device. Through the above scheme, the problem of poor stability of the settling cylinder 3 caused by uneven distribution of the support plates 11 in the water collecting well 1 is solved, and the entire device is more stable during operation, effectively avoiding the problem of reduced water treatment effect caused by unstable position of the settling cylinder 3.

[0063] The support plates 11 can be uniformly distributed in multiple ways. Specifically, the support plates 11 can be installed on the inner wall of the water collecting well 1 by welding, bolt fixing or other connection methods. As a preferred embodiment, the support plates 11 can be made of corrosion-resistant materials to improve their service life and reliability. Further, the number and size of the support plates 11 can be adjusted according to the specific size and structure of the water collecting well 1 to ensure that sufficient support force and stability can be provided.
