Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, and in particular to a building underground drainage device. Background Technology

[0002] Basements, located underground, are susceptible to the effects of groundwater. Therefore, a proper drainage system is crucial for basements, serving to prevent groundwater from impacting the building and ensuring its structural safety and lifespan. If groundwater seeps into the soil, it can reduce soil stability, damaging the building's foundation and structure. Furthermore, accumulated groundwater can cause leaks and humidity problems, affecting the comfort and usability of the building's interior environment.

[0003] The principle of basement drainage systems is based on the flow patterns of groundwater and the permeability of soil. During basement construction, groundwater can easily seep into the basement through the soil, leading to dampness, mold growth, and even groundwater intrusion. Therefore, basement drainage systems, through proper planning and design, aim to keep the basement dry and effectively drain water, preventing groundwater intrusion.

[0004] In cases of poor drainage and the presence of garbage and impurities in the basement, problems such as reduced drainage efficiency, unpleasant odors, and blockage of drainage pipes may occur. In view of this, a building underground drainage device is provided. Utility Model Content

[0005] The main purpose of this utility model is to provide a building underground drainage device to solve the problems mentioned in related technologies, such as reduced drainage efficiency, odor, and blockage of drainage pipes when basement water is not drained properly or when there is garbage or impurities.

[0006] To achieve the above objectives, according to one aspect of the present invention, a building underground drainage device is provided, including a water storage chamber opened on the ground and underground, an inlet connected to the water storage chamber above the water storage chamber, an adjustment part for adjusting the drainage volume is provided at the inlet, a filter plate for separating garbage is fixedly provided below the adjustment part, a brush plate is slidably provided on the filter plate, and a collection box for collecting garbage is provided on one side of the filter plate.

[0007] The adjustment unit includes a cover plate and a float connected to the cover plate. One end of the cover plate is hinged to the side wall of the water inlet, and the float is used to float upwards and open the cover plate when there is a lot of water.

[0008] Furthermore, the upper end of the water inlet is conical, the lower end of the water inlet is cylindrical, and the adjusting part is located at the lower end of the water inlet.

[0009] Furthermore, a groove is provided at one end of the cover plate, a fixing block is fixedly provided at the bottom of the float, the fixing block is inserted into the groove, and a connecting rope is fixedly provided on one side of the cover plate, the other end of the connecting rope is fixedly connected to the side wall of the float.

[0010] Furthermore, the inlet sidewall is provided with a connecting groove, one side of the cover plate is hinged and installed in the connecting groove, and the upper surface of the other side of the cover plate is an arc-shaped design with a high center.

[0011] Furthermore, a sliding groove is provided on one side wall of the water storage cavity. The sliding groove is U-shaped, and one end of the brush plate is slidably installed in the sliding groove.

[0012] Furthermore, the filter plate is fixedly installed inside the water storage cavity, and the filter plate has several densely packed filter holes that penetrate through it. The filter plate also has an embedded deodorizing layer to reduce the odor of the wastewater.

[0013] Furthermore, a number of bristles are fixedly provided at the bottom of the brush plate, and the bristles are stiff bristles.

[0014] Furthermore, a collection port is provided on one side of the collection box, the lower end of the collection port is inclined inward, and connecting blocks are fixedly provided at both ends of the top of the collection port, the connecting blocks being trapezoidal.

[0015] Furthermore, a slot is provided on the ground near the water inlet, the slot is connected to the water storage chamber, and limit grooves are provided on both sides of the slot. The collection box is inserted into the slot, and the connecting block is inserted into the limit groove.

[0016] Furthermore, two layers of downwardly inclined drain pipes are symmetrically arranged on both sides of the water storage cavity, and a branch pipe is fixedly arranged between two adjacent drain pipes, the branch pipe being designed at an inclination.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this underground drainage device for buildings, a fixed part is provided, and a cover plate is rotated around the hinge point by a float to adjust the size of the water inlet. The size of the water inlet can be automatically adjusted according to the amount of water in the basement. When the water is small, the float remains in a low position due to insufficient buoyancy, so that the water inlet is partially closed, allowing only a small amount of water to pass through. When the water increases, the float will float upward with the water level, driving the cover plate to rotate around the hinge point, thereby increasing the opening degree of the water inlet and allowing more water to flow quickly into the water storage chamber. This optimizes the drainage process and improves drainage efficiency.

[0019] 2. In this type of underground drainage device, a filter plate is installed to intercept solid particles, suspended matter and other impurities in the water. The deodorization layer reduces the odor of the water and improves the air quality of the basement. By installing multiple drainage pipes or branch pipes, the drainage pressure can be distributed to prevent a single drainage pipe from being blocked due to overload. Attached Figure Description

[0037] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0038] Please see Figures 1-12 As shown, the purpose of this embodiment is to provide a building underground drainage device, including a ground surface 1 and a water storage cavity 12 opened underground. A water inlet 11 is opened above the water storage cavity 12 and communicates with it. An adjustment part 2 for adjusting the drainage volume is provided at the water inlet 11. A filter plate 5 for separating garbage is fixedly provided below the adjustment part 2. A brush plate 6 is slidably provided on the filter plate 5. A collection box 3 for collecting garbage is provided on one side of the filter plate 5.

[0039] The adjustment part 2 includes a cover plate 21 and a float 22 connected to the cover plate 21. One end of the cover plate 21 is hinged to the side wall of the water inlet 11. The float 22 is used to float upward and open the cover plate 21 when there is a lot of water.

[0040] The upper end of the inlet 11 is conical, which can guide the water generated in the basement to flow into the inlet 11 more smoothly. Secondly, the conical design also increases the receiving area of ​​the inlet 11, so that the water can be collected more effectively. It also helps to reduce the eddies and resistance of the water during the flow process, thereby improving drainage efficiency. The lower end of the inlet 11 is cylindrical, and the adjustment part 2 is located at the lower end of the inlet 11.

[0041] A groove 211 is provided at one end of the cover plate 21. A fixing block 221 is fixedly provided at the bottom of the float 22. The fixing block 221 is square and does not completely cover the water inlet 11. A small amount of water in the basement can smoothly enter the water storage chamber 12 through the water inlet 11. When the amount of water is small, the float 22 remains in a low position due to insufficient buoyancy. The fixing block 221 is inserted into the groove 211 and can act as a cover to block the water inlet 11. A connecting rope 23 is fixedly provided on one side of the cover plate 21. The other end of the connecting rope 23 is fixedly connected to the side wall of the float 22. Therefore, when the float 22 floats, it can move the cover plate 21 upward.

[0042] A connecting groove 111 is provided on the side wall of the inlet 11. The cover plate 21 is hinged to one side in the connecting groove 111, so that the cover plate 21 can rotate around the hinge point when needed, thereby changing the opening degree of the inlet 11. The upper surface of the other side of the cover plate 21 is an arc-shaped design with a high middle. The accumulated water flows down the slope of the cover plate 21, which helps to reduce the accumulation and retention of water on the cover plate 21 and improve drainage efficiency.

[0043] A sliding groove 13 is provided on one side wall of the water storage chamber 12. The sliding groove 13 is U-shaped. One end of the brush plate 6 is slidably installed in the sliding groove 13. Driven by the motor, the brush plate 6 slides along the sliding groove 13 from one side to the collection box 3. During this process, the brush plate 6 sweeps the garbage and impurities on the filter plate 5 towards the collection box 3. When the brush plate 6 slides to the other end of the sliding groove 13, it will encounter an upward turning point. The brush plate 6 slides upward until the next turning point, then slides to the right until the right turning point, and then slides downward along the lower part of the sliding groove 13. Finally, the brush plate 6 will slide along the sliding groove 13 again to the collection box 3. The brush plate 6 reciprocates along a predetermined trajectory. The movement trajectory of the brush plate 6 is a closed loop.

[0044] The filter plate 5 is fixedly installed inside the water storage chamber 12, serving as the first line of defense after the accumulated water enters the water storage chamber 12. The filter plate 5 has several densely packed filter holes 51, and an odor-reducing layer 52 is embedded within it to weaken the odor of the wastewater. This is to reduce the odor that the accumulated water may produce. The odor-reducing layer 52 is typically made of materials with the ability to adsorb, neutralize, or decompose odor substances, such as activated carbon, zeolite, and photocatalysts. These materials can effectively adsorb or decompose organic pollutants and odor substances in the accumulated water, thereby reducing the odor of the accumulated water.

[0045] A number of bristles 61 are fixedly provided at the bottom of the brush plate 6. The bristles 61 are hard bristles, preferably made of nylon, pig bristles, or horsehair. Nylon bristles 61 have the characteristics of high strength, good wear resistance, and strong corrosion resistance, and are suitable for most wastewater treatment environments. Pig bristle and horsehair bristles 61 have natural oil components, which can better adsorb and remove dirt and impurities on the surface of the filter plate 5 without damaging the surface of the filter plate 5. Even when the filter plate 5 is wet, the bristles 61 can sweep the garbage on it to the collection box 3. This is because the bristles 61 have a certain degree of elasticity and toughness, which can adapt to the wet state of the surface of the filter plate 5 and effectively sweep the garbage and impurities out of the filter holes 51.

[0046] A collection port 32 is provided on one side of the collection box 3. In order to facilitate the collection of garbage and impurities swept off the filter plate 5, the lower end of the collection port 32 is inclined inward, which helps the garbage and impurities to slide smoothly into the collection box 3 under the action of gravity, avoiding the accumulation and retention of garbage at the collection port 32. Connecting blocks 31 are fixedly provided at both ends of the top of the collection port 32. The connecting blocks 31 are trapezoidal, and the shorter side of the trapezoid is outward, forming a natural gripping space, which makes it easy for the hand to grasp the connecting blocks 31, thereby making it easy to pick up the collection box 3.

[0047] A slot 14 is provided on the ground 1 near the water inlet 11. The slot 14 is connected to the water storage chamber 12. Limiting grooves 141 are provided on both sides of the slot 14. The collection box 3 is inserted into the slot 14. The connecting block 31 is inserted into the limiting groove 141 to prevent the collection box 3 from falling into the water storage chamber 12 and to play a limiting role.

[0048] Two layers of downward-sloping drain pipes 4 are symmetrically arranged on both sides of the water storage chamber 12, which helps the water in the water storage chamber 12 to flow smoothly to the drain well. Because the drain pipes 4 are downward-sloping, the water can flow naturally to the opening of the drain pipes 4 under the action of gravity, thereby avoiding the water from stagnating in the water storage chamber 12. A branch pipe 41 is fixedly arranged between two adjacent drain pipes 4. The branch pipe 41 is designed with an inclination. The arrangement of the branch pipe 41 not only increases the flow path of the water, but also helps to reduce the blockage of the water. When there is a lot of water in the water storage chamber 12, some of the water may flow to the adjacent drain pipe 4 through the branch pipe 41, thereby dispersing the drainage pressure and avoiding the risk of a single drain pipe 4 being blocked due to overload.

[0049] In practical use, the collection box 3 is inserted into the slot 14, and the connecting block 31 is inserted into the limiting groove 141. When water accumulates in the basement, the water first flows into the inlet 11. If the water volume in the storage chamber 12 is small, the float 22 remains low due to insufficient buoyancy, and the fixing block 221 is inserted into the groove 211 of the cover plate 21. If the water volume increases, the float 22 will float upward with the rise in water level. Since the float 22 is connected to the cover plate 21 by the connecting rope 23, the rise of the float 22 will drive the cover plate 21 to rotate around the hinge point, thereby increasing the opening degree of the inlet 11 and allowing more water to accumulate quickly. Water flows into the water storage chamber 12. After entering the water storage chamber 12, the water first passes through the filter plate 5, which intercepts solid particles and suspended matter. The deodorizing layer 52 embedded in the filter plate 5 reduces the odor of the water. Driven by the motor, the brush plate 6 moves back and forth along the slide groove 13. The bristles 61 fixed at the bottom sweep across the surface of the filter plate 5, sweeping garbage and impurities toward the collection box 3. The water in the water storage chamber 12 is smoothly discharged through the drain pipes 4 on both sides and flows to the drain well. The branch pipe 41 increases the flow path of the water. When it is necessary to clean the collection box 3, the user can grab the connecting block 31 and take the collection box 3 out of the slot 14.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
