Description

Technical Field

[0001] This utility model relates to the field of underground engineering drainage technology, and in particular to a drainage structure for an underground garage. Background Technology

[0002] With the continuous development of urban construction, underground parking garages, as an important component of urban parking facilities, are increasing in number and scale. However, due to their unique geographical location, underground parking garages are highly susceptible to water accumulation caused by rainwater, pipe leaks, and other factors. Water accumulation not only damages vehicles parked inside but can also trigger electrical equipment malfunctions, structural corrosion, and a series of other safety hazards, seriously affecting the normal use and safety of underground parking garages.

[0003] Currently, most existing underground parking garage drainage structures use a simple combination of drainage ditches and sump pits. This drainage structure has several shortcomings: First, the filtration function of the drainage structure is poor. During the drainage process, garbage and debris can easily enter the drainage ditches and sump pits, causing blockages, reducing drainage efficiency, and even leading to drainage system failure. Second, the water flow in the sump pits is relatively chaotic, making it impossible to effectively settle and filter the water. This results in the water pumped by the pumps containing more impurities, which can easily wear down the pumps and shorten their service life. Third, the installation and maintenance of the drainage structure are inconvenient. When drainage components malfunction, maintenance personnel cannot quickly and easily inspect and replace them, increasing maintenance costs and time. Utility Model Content

[0004] This utility model mainly addresses the problems of poor filtration effect, chaotic water flow, and inconvenient installation and maintenance in existing underground garage drainage structures, and provides a new underground garage drainage structure.

[0005] The objective of this utility model is mainly achieved through the following solution:

A sump is provided in the middle of the underground pit, and the top of the sump is a parking space. A water collection trough is formed between the sump and the underground pit, and the top of the water collection trough is provided with several filter components covering its opening. A water inlet pipe is connected to the lower part of one side of the sump, and a water pump is installed on the side of the sump away from the water inlet pipe. The outlet of the water pump is connected to an outlet pipe extending out of the sump.

[0007] Preferably, the water filtration assembly includes a water collection cylinder, a water filter basket, and a top cover. The water collection cylinder has a square structure with a hollow interior and an open top. The top cover has several water filter grooves, and one side of the top cover is rotatably connected to the upper side of the water collection cylinder. The water filter basket can be detachably placed inside the water collection cylinder, and a water pipe is installed in the center of the bottom of the water collection cylinder. The upper and lower ends of the water pipe protrude from the upper and lower surfaces of the bottom of the water collection cylinder, respectively.

[0008] Preferably, the water filter basket is a hollow basket with an open top, and the bottom of the water filter basket has a plurality of water filter holes evenly distributed. The top of the water filter basket has a first limiting plate extending outward around its perimeter. The inside of the water collection cylinder has a limiting step, and the first limiting plate is placed on the upper surface of the limiting step.

[0009] Preferably, a second limiting plate extends outward around the top of the water collection cylinder, and limiting grooves are provided on the inner edge of the top of the underground foundation pit and the outer edge of the top of the water collection well. The second limiting plate is placed on the upper surface of the limiting groove.

[0010] Preferably, the two opposite outer walls of the water collecting cylinder are provided with a set of elastic metal plates, which can abut against the inner wall of the water collecting tank.

[0011] Preferably, the water collection well is provided with multiple partition frames along its length. The partition frames are U-shaped and the side walls of the partition frames are provided with U-shaped slots. Each U-shaped slot is fitted with a water-blocking plate, and a filter screen is embedded in the upper part of the water-blocking plate.

[0012] Preferably, the baffle plate divides the water collection well into multiple water inlet chambers and one water pumping chamber, the water pump is located in the water pumping chamber, and the water inlet pipe is connected to the water inlet chamber away from the water pumping chamber.

[0013] Preferably, the top of the water collection well is fitted with a well cover, the upper surface of the water collection well is provided with a ring of spiral grooves, and the lower surface of the well cover is provided with a ring of limiting protrusions that match the spiral grooves, the limiting protrusions being able to engage with the spiral grooves.

[0014] Preferably, the upper surface of the baffle plate is provided with multiple limiting grooves, and the bottom of the manhole cover is provided with a limiting post that cooperates with the limiting grooves.

[0015] Preferably, both the inlet chamber and the pumping chamber are equipped with ladders, and an observation door is rotatably connected to the manhole cover at a position corresponding to the pumping chamber, with the outlet pipe extending out of the collection well from the observation door.

[0016] Therefore, compared with the prior art, the present invention has the following advantages:

The water flows through each water inlet chamber in sequence, and sedimentation and filtration are achieved during the flow process, which greatly reduces the impurity content of the water entering the water pumping chamber, effectively protects the water pump, and extends its service life. The filter screen on the upper part of the water baffle ensures the flow of water on the one hand, and further filters impurities in the water on the other hand, ensuring that the water pumping the water pump is clean.

[0019] (3) In this utility model, the water collection cylinder of the water filter assembly is installed by the second limiting plate in conjunction with the limiting groove of the underground foundation pit and the water collection well.

The well cover of the water collection well is fastened to the U-shaped groove by the limiting protrusion, and the limiting post at the bottom of the well cover is in conjunction with the limiting groove of the water baffle plate. The installation is stable and easy to disassemble. The ladders in the water inlet chamber and the pumping chamber facilitate the entry and exit of maintenance personnel. The observation door on the well cover facilitates the observation of the water level in the pumping chamber and the inspection and maintenance of the pumping pump, which greatly reduces the maintenance cost and time cost.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0031] Example 1:

[0032] like Figure 1 As shown, this utility model provides a technical solution, an underground garage drainage structure, including an underground pit 1 that is hollow inside and open at the top. A water collection well 2 is poured in the middle of the underground pit 1. The top of the water collection well 2 is a parking space. A water collection trough 3 is formed between the water collection well 2 and the underground pit 1. Several filter components 4 covering the opening of the water collection trough 3 are detachably installed on the top of the water collection trough 3. A water inlet pipe 5 is connected to the lower part of one side of the water collection well 2. A water pump 6 is fixedly installed on the side of the water collection well 2 away from the water inlet pipe 5 by bolts. The outlet of the water pump 6 is connected to an outlet pipe 7 that extends out of the water collection well 2. A protective net frame is provided on the outside of the water pump 6.

[0033] Water in the underground garage can be initially filtered by the filter assembly 4 and then flow into the collection tank 3. It is then collected into the collection well 2 through the inlet pipe 5. The outlet pipe 7 can be connected to the external drainage system. The water pump 6 works in conjunction with the outlet pipe 7 to discharge the water in the collection well 2 in a timely manner, effectively preventing water accumulation in the underground garage and ensuring the safety of vehicles and facilities in the garage. The water pump 6 can be purchased from the market and adopts existing technology. Its specific structure and working principle are not within the scope of protection of this application and will not be described here.

[0034] Example 2:

[0035] like Figure 6 , 7 As shown in Figure 8, this utility model provides another technical solution, a drainage structure for an underground garage. The difference from embodiment 1 is that the water filter assembly 4 consists of a water collection cylinder 8, a water filter basket 9, and a top cover 10. The water collection cylinder 8 adopts a square structure with a hollow interior and an open top. The top cover 10 has several water filter grooves 11, and one side of the top cover 10 is rotatably connected to the upper side of the water collection cylinder 8 through a hinge. The water filter basket 9 can be detachably placed inside the water collection cylinder 8, and a water pipe 12 is welded to the center of the bottom of the water collection cylinder 8. The upper and lower ends of the water pipe 12 protrude from the upper and lower surfaces of the bottom of the water collection cylinder 8, respectively. The water filter grooves 11 of the top cover 10 can intercept larger debris and prevent it from entering the water collection trough 3. The detachable design of the water filter basket 9 makes it easy to clean the intercepted debris and ensure the filtration effect. The water pipe 12 can guide the filtered water to flow smoothly into the water collection trough 3, ensuring a smooth drainage process.

[0036] Specifically, the water filter basket 9 is a hollow basket with an open top, and multiple filter holes 13 are evenly distributed at the bottom of the water filter basket 9. A first limiting plate 14 is integrally provided on the top of the water filter basket 9 extending outwards around its perimeter. A limiting step 15 is welded or integrally bent inside the water collecting cylinder 8. The first limiting plate 14 is placed on the upper surface of the limiting step 15. A buffer baffle 16 is welded to the center of the bottom of the water filter basket 9. The buffer baffle 16 is located directly above the water pipe 12. The upper part of the buffer baffle 16 is conical, and the lower part is cylindrical. The filter holes 13 at the bottom of the water filter basket 9 can further filter smaller impurities. The first limiting plate 14 and the limiting step 15 cooperate to make the water filter basket 9 securely installed and easy to disassemble. The buffer baffle 16 can reduce the impact of water flow, extend the service life of the water filter assembly 4, and improve the filtration efficiency.

[0037] Specifically, a second limiting plate 17 is integrally provided on the top four sides of the water collection cylinder 8, extending outwards. Limiting grooves 18 are provided on the inner four sides of the top of the underground foundation pit 1 and the outer four sides of the top of the water collection well 2. The second limiting plate 17 is placed on the upper surface of the limiting groove 18. Through the cooperation of the second limiting plate 17 and the limiting groove 18, the water collection cylinder 8 can be quickly positioned and installed. The installation process is simple and convenient, and the structure is stable after installation, ensuring that the water filter assembly 4 will not be displaced during normal use, and ensuring the normal operation of the drainage system.

[0038] Specifically, a set of elastic metal plates 19 are welded to the two opposite outer walls of the water collecting cylinder 8. The elastic metal plates 19 can abut against the inner wall of the water collecting trough 3. The elasticity of the elastic metal plates 19 can make the water collecting cylinder 8 fit tightly with the water collecting trough 3, thereby enhancing the stability of the installation of the water collecting cylinder 8.

[0039] Example 3:

[0040] like Figure 2-5 As shown, this utility model provides another technical solution, an underground garage drainage structure, which differs from embodiment 1 in that multiple partition frames 20 are bolted along the length of the water collection well 2. The partition frames 20 have a U-shaped structure, and U-shaped slots 21 are provided on the side walls of the partition frames 20. A water-blocking plate 22 is inserted into each U-shaped slot 21. A filter screen 23 is embedded in the upper part of the water-blocking plate 22. The water-blocking plate 22 divides the water collection well 2 into multiple water inlet chambers 24 and a water pumping chamber 25. The water pump 6 is located in the water pumping chamber 25, and the water inlet pipe 5 is connected to the water inlet chamber 24 away from the water pumping chamber 25. The partition frames 20 and the water-blocking plate 22 cooperate to divide the water collection well 2 into multiple areas, so that the water flow can flow in an orderly manner in the water collection well 2, and achieve sedimentation and filtration by passing through each area in sequence. The filter screen 23 on the upper part of the water-blocking plate 22 further intercepts impurities in the water, improves the water quality entering the water pumping chamber 25, effectively protects the water pump 6, and extends its service life.

[0041] Specifically, a manhole cover 26 is fastened to the top of the water collection well 2. A ring of grooves 27 is formed on the upper surface of the water collection well 2. A ring of limiting protrusions 28 matching the grooves 27 is integrally formed on the lower surface of the manhole cover 26. The limiting protrusions 28 can be fastened into the grooves 27. Through the fastening of the limiting protrusions 28 and the grooves 27, a stable connection between the manhole cover 26 and the water collection well 2 is achieved, preventing the manhole cover 26 from shifting or lifting under the action of vehicles or other external forces, ensuring the safety of personnel and vehicles. At the same time, it facilitates the opening and closing of the manhole cover 26, making it convenient for the inspection and maintenance of the water collection well 2.

[0042] Specifically, the upper surface of the baffle plate 22 is provided with multiple limiting grooves 29, and the bottom of the manhole cover 26 is provided with limiting posts 30 that cooperate with the limiting grooves 29; the limiting posts 30 cooperate with the limiting grooves 29 to further enhance the stability of the manhole cover 26 installation and ensure that the manhole cover 26 will not shake after installation.

[0043] Specifically, ladders 31 are installed in both the inlet chamber 24 and the pumping chamber 25. An observation door 32 is hinged to the manhole cover 26 at the position corresponding to the pumping chamber 25. The outlet pipe 7 extends from the observation door 32 into the collection well 2. Steps are provided on the manhole cover 26 at the position where the observation door 32 is installed, making it convenient for the observation door 32 to be erected on the steps. The ladders 31 facilitate maintenance personnel to enter and exit the inlet chamber 24 and the pumping chamber 25 to inspect, repair and clean the internal equipment. When the observation door 32 is open, it is convenient to observe the water level in the pumping chamber 25 and the operating status of the pumping pump 6. At the same time, the outlet pipe 7 extends from the observation door 32, making reasonable use of space and facilitating the inspection and maintenance of the outlet pipe 7, reducing maintenance costs and time costs.

[0044] This utility model provides a drainage structure for an underground garage. During installation, firstly, an underground foundation pit 1 is excavated according to design requirements, ensuring that the size and depth of the pit meet the specified standards. A water collection well 2 is poured in the center of the pit 1, forming a water collection trough 3 between the well 2 and the pit 1. A partition frame 20 is installed inside the well 2, and water-blocking plates 22 are sequentially inserted into U-shaped slots 21, dividing the well 2 into multiple inlet chambers 24 and one pumping chamber 25. The inlet pipe 5 is connected to the inlet chamber 24 furthest from the pumping chamber 25. A pumping pump 6 is installed inside the pumping chamber 25, and an outlet pipe 7 is connected to the outlet of the pumping pump 6. Then, the manhole cover 26 is secured by a limiting protrusion. The snap-fit ​​installation of the manhole cover 26 with the groove 27 is completed on the top of the water collection well 2. At the same time, the limiting post 30 is inserted into the limiting groove 29 to ensure that the manhole cover 26 is installed firmly. The observation door 32 is installed on the manhole cover 26 at the position corresponding to the pumping chamber 25, so that the observation door 32 can rotate normally and be flush with the manhole cover 26 when rotated to the horizontal position. The water outlet pipe 7 extends out of the water collection well 2 from the observation door 32. Finally, multiple water filter components 4 are placed in the limiting groove 18 at the top of the water collection tank 3 in sequence, so that the second limiting plate 17 is placed on the upper surface of the limiting groove 18. At the same time, the elastic metal plate 19 is adjusted to abut against the inner wall of the water collection tank 3 to ensure that the water collection cylinder 8 is installed firmly, thus completing the installation of the entire underground garage drainage structure.

[0045] This utility model provides a drainage structure for an underground garage. When water accumulates in the underground garage, it flows into a filter basket 9 through the filter trough 11 on the top cover 10. Larger debris is intercepted by the filter trough 11, while smaller debris is filtered by the filter basket 9. The filtered water flows into a collection trough 3 through the filter holes 13 at the bottom of the filter basket 9 and the water pipe 12. Then, it flows into the inlet chamber 24 of the collection well 2 through the collection trough 3. During the flow of water in the inlet chamber 24, impurities such as mud and sand gradually settle. After sedimentation in multiple inlet chambers 24 and filtration by the filter screen 23 on the upper part of the baffle plate 22, the relatively clean water enters the pumping chamber 25. The pumping pump 6 is started, and the water in the pumping chamber 25 is discharged from the underground garage through the outlet pipe 7, completing the drainage process.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
