Abstract
Description
Technical Field
[0001] This invention relates to the field of drainage technology, and more particularly to a drainage structure that prevents clogging. Background Technology
[0002] Currently, summer rainfall is increasing, especially in the southern regions where heavy rain is frequent. The drainage outlets of substation drainage ditches are often blocked by weeds, silt and other foreign objects. Once drainage is not smooth, water accumulation can easily occur, causing flooding and affecting the safe and stable operation of power equipment. Therefore, maintenance personnel need to clean the foreign objects at the drainage outlets in a timely manner. However, excessively frequent blockages will require a lot of manpower. Summary of the Invention
[0003] This invention provides a clog-resistant drainage ditch structure to solve the technical problem that existing drainage outlets are often blocked by weeds, silt and other foreign objects, which easily leads to poor drainage, waterlogging and affects the safe and stable operation of power equipment.
[0004] The present invention provides a clog-resistant drainage ditch structure, comprising: a drainage ditch body;
[0005] The drainage ditch body includes multiple drainage ditch units, each drainage ditch unit has a drainage outlet, and a filter screen group is provided on one side of each drainage outlet, the filter screen group including an upper filter screen and a lower filter screen;
[0006] The upper and lower filter screens are spaced apart along the length of the drainage ditch unit;
[0007] The upper filter screen is installed on the inner wall of the drainage ditch unit, and the upper end face of the upper filter screen is flush with the upper end face of the drainage ditch unit. The lower filter screen is installed on the inner bottom wall of the drainage ditch unit.
[0008] The heights of both the upper and lower filter screens are less than the depth of the drainage ditch unit.
[0009] Preferably, the depth of the drainage ditch unit decreases sequentially from the drain outlet in the direction away from the drain outlet.
[0010] Preferably, the lower filter screen has no mesh holes on the surface near the bottom wall of the drainage ditch unit.
[0011] Preferably, a strip grate is provided above the drain outlet, the length of the strip grate is greater than the diameter of the drain outlet, and a channel is formed between the strip grate and the drain outlet.
[0012] Preferably, the channel formed between the strip grate and the drain outlet is funnel-shaped.
[0013] Preferably, the filter assembly is also provided on the other side of the drain outlet.
[0014] Preferably, the widths of the upper filter screen and the lower filter screen are the same as the inner width of the drainage ditch unit.
[0015] Preferably, the upper end face of the drainage ditch unit is covered with a drainage ditch cover.
[0016] Preferably, the cross-section of the inner wall of the drainage ditch unit is U-shaped.
[0017] Preferably, there are multiple filter groups.
[0018] This invention provides a clog-resistant drainage channel structure with the following advantages:
[0019] The system includes: a drainage ditch body; the drainage ditch body comprises multiple drainage ditch units, each drainage ditch unit having a drain outlet, and a filter screen assembly on one side of each drain outlet, the filter screen assembly comprising an upper filter screen and a lower filter screen; the upper filter screen and the lower filter screen are spaced apart along the length of the drainage ditch unit; the upper filter screen is installed on the inner wall of the drainage ditch unit, the upper end face of the upper filter screen being flush with the upper end face of the drainage ditch unit, and the lower filter screen is installed on the inner bottom wall of the drainage ditch unit; the height of both the upper and lower filter screens is less than the depth of the drainage ditch unit.
[0020] This invention opens a drain outlet at the bottom of the drainage ditch unit and sets up a filter screen group on one side of the drain outlet. The filter screen group includes an upper filter screen and a lower filter screen, which are distributed at intervals along the length of the drainage ditch unit. Thus, the water flows through the upper filter screen and the lower filter screen in succession or through the lower filter screen and the upper filter screen in succession before being discharged from the drain outlet. This avoids debris clogging the drain outlet, reduces the frequency of debris cleaning by maintenance personnel, and saves manpower.
[0021] Since the height of both the upper and lower filters is less than the depth of the drainage unit, and the upper filter is installed on the inner wall of the drainage unit with its upper surface flush with the upper surface of the drainage unit, the upper filter can filter impurities with a density less than water when the water level in the drainage unit is high. The lower filter, installed on the inner bottom wall of the drainage unit, can filter impurities with a density greater than water. When the water level is low and the water flow does not pass through the upper filter, the lower filter can still filter impurities with a density less than water.
[0022] There is a certain distance between the lower end face of the upper filter screen and the inner bottom wall of the drainage unit. Even if the upper filter screen is clogged, the water flow can pass through the bottom of the upper filter screen, effectively preventing the water flow from being completely blocked by the upper filter screen and improving the smoothness of drainage.
[0023] Even if the lower filter screen becomes clogged, the water level will be raised, allowing water to flow over the top of the screen. This effectively prevents the water flow from being completely blocked by the lower filter screen, improves drainage, reduces water accumulation, effectively avoids flooding, and ensures the safe and stable operation of the substation's electrical equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.
[0034] This invention provides a clog-resistant drainage ditch structure to solve the technical problem that existing drainage outlets are often blocked by weeds, silt and other foreign objects, which easily leads to poor drainage, waterlogging and affects the safe and stable operation of power equipment.
[0035] Please see Figure 1-2 An embodiment of the present invention provides an anti-clogging drainage ditch structure, comprising: a drainage ditch body;
[0036] The drainage ditch body includes multiple drainage ditch units 1. Each drainage ditch unit 1 has a drainage outlet 5. A filter screen group is provided on one side of the drainage outlet 5. The filter screen group includes an upper filter screen 2 and a lower filter screen 3.
[0037] The upper filter screen 2 and the lower filter screen 3 are distributed at intervals along the length of the drainage ditch unit 1;
[0038] The upper filter screen 2 is installed on the inner wall of the drainage ditch unit 1, and the upper end face of the upper filter screen 2 is flush with the upper end face of the drainage ditch unit 1. The lower filter screen 3 is installed on the inner bottom wall of the drainage ditch unit 1.
[0039] The heights of both the upper filter screen 2 and the lower filter screen 3 are less than the depth of the drainage ditch unit 1.
[0040] It should be noted that the present invention provides a drain outlet 5 at the bottom of the drainage ditch unit 1 and a filter screen group on one side of the drain outlet 5. The filter screen group includes an upper filter screen 2 and a lower filter screen 3, which are distributed at intervals along the length of the drainage ditch unit 1. Thus, the water flows through the upper filter screen 2 and the lower filter screen 3 or through the lower filter screen 3 and the upper filter screen 2 in succession before being discharged from the drain outlet 5. This avoids debris clogging the drain outlet, reduces the frequency of cleaning debris by maintenance personnel, and saves manpower.
[0041] Since the heights of both the upper filter screen 2 and the lower filter screen 3 are less than the depth of the drainage ditch unit 1, and the upper filter screen 2 is installed on the inner wall of the drainage ditch unit 1 with its upper surface flush with the upper surface of the drainage ditch unit 1, when the water level in the drainage ditch is high, the upper filter screen 2 can filter out debris with a density less than water (such as weeds, plastics, etc.). The lower filter screen 3, installed on the inner bottom wall of the drainage ditch unit 1, can filter out debris with a density greater than water (such as ironware, stones, etc.). When the water level is low and the water flow does not pass through the upper filter screen 2, the lower filter screen 3 can also filter out debris with a density less than water.
[0042] There is a certain distance between the lower end face of the upper filter screen 2 and the inner bottom wall of the drainage ditch unit 1. Even if the upper filter screen 2 is blocked, the water flow can pass through the bottom of the upper filter screen 2, effectively preventing the water flow from being completely blocked by the upper filter screen 2 and improving the smoothness of drainage.
[0043] Even if the lower filter screen 3 becomes clogged, the water level will be raised, and the water flow can pass over the lower filter screen 3, effectively preventing the water flow from being completely blocked by the lower filter screen 3, improving the smoothness of drainage, reducing the generation of water accumulation, effectively avoiding the occurrence of waterlogging, and ensuring the safe and stable operation of the substation's power equipment.
[0044] The drain outlet 5 can be opened on the bottom wall of the drainage ditch unit 1 or on the side wall of the drainage ditch unit 1.
[0045] In another, more specific embodiment, the upper filter screen 2 is arranged perpendicular to the inner wall of the drainage ditch unit 1, and the lower filter screen 3 is arranged perpendicular to the inner wall of the drainage ditch unit 1, so as to effectively utilize the area of the filter screen for filtration.
[0046] Please see Figure 2-3 In a more specific embodiment, the depth of the drainage ditch unit 1 decreases sequentially from the drain outlet 5 toward the direction away from the drain outlet 5.
[0047] It should be noted that the depth of the drainage ditch unit 1 decreases gradually from the drain outlet 5 toward the direction away from the drain outlet 5, forming a slope so that the water flow can be concentrated toward the drain outlet 5 and the drainage speed can be accelerated.
[0048] Please see Figure 1In a more specific embodiment, the lower filter screen 3 has no mesh holes on the surface near the bottom wall of the drainage unit 1.
[0049] It should be noted that the lower filter screen 3 has no mesh holes on the surface near the bottom wall of the drainage ditch unit 1; that is, the upper part of the lower filter screen 3 has mesh holes, while the lower part does not. The upper part with mesh holes is used to filter the water flow, while the lower part without mesh holes is used to block silt flowing with the water, thus preventing clogging of the mesh holes.
[0050] Please see Figure 2 In a more specific embodiment, a strip grate 4 is provided above the drain outlet 5. The length of the strip grate 4 is greater than the diameter of the drain outlet 5, and a channel is formed between the strip grate 4 and the drain outlet 5.
[0051] It should be noted that the drain outlet 5 is a round hole. The water first passes through the strip grate 4, and then through the channel between them to reach the drain outlet 5. The length of the strip grate 4 is greater than the diameter of the drain outlet 5. The strip grate 4 has multiple holes, which increases the drainage area and improves the smoothness of drainage in the drainage ditch.
[0052] In another, more specific embodiment, the strip grate 4 is embedded in the inner wall of the drainage ditch unit 1 to prevent water from being blocked by the side of the strip grate 4, thus preventing water from flowing smoothly into the holes on the strip grate 4.
[0053] Please see Figure 3 In a more specific embodiment, the channel formed between the strip grate 4 and the drain outlet 5 is funnel-shaped.
[0054] It should be noted that, since the length of the strip grate 4 is greater than the diameter of the drain outlet 5, the channel formed between the strip grate 4 and the drain outlet 5 is designed as a funnel shape in order to speed up the water flow.
[0055] Please see Figure 1 In a more specific embodiment, a filter screen assembly is also provided on the other side of the drain outlet 5.
[0056] It should be noted that the other side of the drain outlet 5 is also equipped with a filter assembly including an upper filter screen 2 and a lower filter screen 3, so that water can be drained from both directions, making it suitable for more scenarios.
[0057] Please see Figure 1 In a more specific embodiment, the widths of both the upper filter screen 2 and the lower filter screen 3 are the same as the inner width of the drainage ditch unit 1.
[0058] It should be noted that the width of both the upper filter screen 2 and the lower filter screen 3 is the same as the inner width of the drainage ditch unit 1. Thus, both sides of the upper filter screen 2 and the lower filter screen 3 are installed and connected to the inner wall of the drainage ditch unit 1, which improves the stability of the installation, can resist the impact of large water flow, and can prevent debris from passing through the gap between the filter screen and the inner wall, thereby improving the filtration effect.
[0059] In another more specific embodiment, the sum of the height of the upper filter screen 2 and the height of the lower filter screen 3 is not less than the depth of the drainage ditch unit 1, so that water flow will pass through the filter screen (upper filter screen 2 or lower filter screen 3) regardless of the water level, thereby improving the filtration effect.
[0060] Preferably, the height of the upper filter screen 2 and the height of the lower filter screen 3 are both two-thirds of the depth of the drainage ditch unit 1.
[0061] In a more specific embodiment, a drainage ditch cover (not shown) overlaps the upper end face of the drainage ditch unit 1.
[0062] It should be noted that the upper surface of drainage ditch unit 1 is covered with a drainage ditch cover to prevent debris from falling into drainage ditch unit 1 with the wind.
[0063] The drain cover is installed between the two upper filter screens 2 closest to the drain outlet 5.
[0064] Please see Figure 1 In a more specific embodiment, the cross-section of the inner wall of the drainage ditch unit 1 is U-shaped.
[0065] It should be noted that, compared to square inner walls, U-shaped inner walls can prevent foreign objects from accumulating in the corners of the inner walls for a long time.
[0066] In a more specific embodiment, there are multiple filter assemblies.
[0067] It should be noted that setting multiple filter groups can improve the filtration effect; the specific number of groups should be set according to the actual situation.
[0068] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
