Description

Technical Field

[0001] This utility model relates to the field of water collection well pressure relief technology, specifically a pressure relief device for an anti-buoyancy water collection well in a basement. Background Technology

[0002] With the rapid development of urbanization in my country, the development of underground space is increasing, leading to a growing number of projects requiring ultra-deep and ultra-large basements. Constrained by surrounding environment, engineering geology, and hydrogeology, many new technical problems have emerged in the design and construction of basements, one of which is the issue of basement buoyancy resistance.

[0003] There are two main stages that can lead to basement uplift. First, during construction, if the basement roof is not covered with soil and the construction company fails to properly implement wellpoint dewatering, there is a risk of basement uplift. Second, during use, sudden heavy rain or flooding can cause the groundwater level to rise above the anti-uplift design level, also posing a risk of basement uplift. Since underground parking garages typically have multiple sump systems, and the bottom of these sump systems is lower than the garage floor, using sump systems to release pressure and reduce the impact of water pressure on the underground parking garage is a good measure. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure relief device for an anti-buoyancy water collection well in a basement to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a basement anti-buoyancy water collection well pressure relief device, comprising a water collection well, an inner well installed inside the water collection well, a support structure installed outside the inner well, an installation groove opened at the upper end of the inner well, a rotating shaft installed inside the installation groove, a flip cover rotatably connected to the surface of the rotating shaft, the size of the flip cover being adapted to the opening size of the inner well, a groove opened at a position symmetrical to the installation groove at the upper end of the inner well, a tension spring installed inside the groove, an extension plate installed at the end of the flip cover away from the rotating shaft, and the lower end of the extension plate being connected to the upper end of the tension spring.

[0006] Preferably, the support structure includes a fixing ring, a longitudinal support rod, and a lateral support plate. Two fixing rings are installed on the outside of the inner well, and multiple longitudinal support rods are installed between the two fixing rings. Multiple lateral support plates are arrayed on the outer surfaces of the two fixing rings.

[0007] Preferably, a water level sensor is installed inside the water collection well, and a water pump is installed inside the water collection well at a position outside the inner well. Both the water level sensor and the water pump are electrically connected to an external control platform.

[0008] Preferably, the upper side surface of the inner well is arrayed with multiple side drainage holes.

[0009] Preferably, the inner diameter of the side drain hole is smaller than the thickness of the flip cover.

[0010] Preferably, the extension plate is located at the upper end of the inner well, and the flap is located inside the opening of the inner well.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This basement anti-buoyancy sump water relief device consists of a sump water well, an inner well, a flap cover, and a replaceable spring. Under safe conditions, the buoyancy force is less than the spring tension, and the flap cover is closed. When the anti-buoyancy water level exceeds the warning line, the buoyancy force is greater than the spring tension, the flap cover opens, and water from outside the basement flows into the sump water well. The sump water pump automatically starts to pump water, reducing the water pressure. After the water pressure decreases, the spring tension is greater than the buoyancy force, and the cover closes. By setting up a sump water well and an inner well, the impact of water pressure on the underground garage can be effectively reduced. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, the basement anti-buoyancy sump pressure relief device in this embodiment includes a sump 1, the elevation of which is lower than that of the basement. An inner well 5 is installed inside the sump 1, with its lower end connected to the external environment. A support structure 4 is installed outside the inner well 5, providing a certain pressure resistance. An installation groove 11 is provided at the upper end of the inner well 5, and a rotating shaft 10 is installed inside the groove 11. A flip cover 7 is rotatably connected to the surface of the rotating shaft 10. The flip cover 7 can be flipped along the center of the rotating shaft 10. The size of the flip cover 7 matches the opening size of the inner well 5. When there is no external force, the flip cover 7 will be located at the opening of the inner well 5, sealing it. A groove is provided symmetrically at the upper end of the inner well 5 and the installation groove 11. The groove is equipped with a tension spring 9, which is a detachable and replaceable spring. Depending on the spring's stiffness coefficient (i.e., the spring tension), and the different anti-buoyancy water pressures of different projects, a spring matching the corresponding water pressure can be replaced. An extension plate 8 is installed at the end of the flip cover 7 away from the pivot 10. The lower end of the extension plate 8 is connected to the upper end of the tension spring 9. In a safe state, the buoyancy force is less than the spring tension, and the flip cover 7 is closed. When the anti-buoyancy water level exceeds the warning line, the buoyancy force is greater than the spring tension, the flip cover 7 is opened, and water from outside the basement flows into the collection well 1. The water pump in the collection well 1 automatically starts to pump water to reduce the water pressure. After the water pressure decreases, the spring tension is greater than the buoyancy force, and the cover closes. By setting up the collection well 1 and the internal well 5, the impact of water pressure on the underground garage can be effectively reduced.

[0020] Specifically, the support structure 4 includes a fixing ring 401, a longitudinal support rod 402, and a lateral support plate 403. Two fixing rings 401 are installed on the outside of the inner well 5, and multiple longitudinal support rods 402 are installed between the two fixing rings 401. Multiple lateral support plates 403 are arrayed on the outer surface of the two fixing rings 401. By setting two fixing rings 401 and multiple longitudinal support rods 402, a certain support effect can be provided for the inner well 5. After external water enters the inside of the water collection well 1, the fixing rings 401 and multiple longitudinal support rods 402 can further stabilize the position of the inner well 5. The multiple lateral support plates 403 can provide lateral support for the inner well 5.

[0021] Furthermore, a water level sensor 2 is installed inside the water collection well 1, and a water pump 3 is installed inside the water collection well 1 at a position outside the inner well 5. Both the water level sensor 2 and the water pump 3 are electrically connected to an external control platform. The water level sensor 2 will transmit the water level information to the external control platform in real time. When the water level inside the water collection well 1 exceeds the danger level, the external control platform will start the water pump 3 to pump water out of the water collection well 1.

[0022] Furthermore, the upper side surface of the inner well 5 is arrayed with multiple side drainage holes 6. The inner diameter of the side drainage holes 6 is smaller than the thickness of the flip cover 7. The extension plate 8 is located at the upper end of the inner well 5, and the flip cover 7 is located inside the opening of the inner well 5. When the flip cover 7 is located at the opening of the inner well 5, the side wall of the flip cover 7 will close the multiple side drainage holes 6. When the flip cover 7 is flipped up by the buoyancy of the water inside the water collection well 1, the side drainage holes 6 will be opened, and the water inside the water collection well 1 will be discharged from the side drainage holes 6. The pressure on the flip cover 7 and the inner well 5 can be reduced through the side drainage holes 6.

[0023] The usage method of this embodiment is as follows: It consists of a water collection well 1, an inner well 5, a flip cover 7, and a replaceable spring. Under safe conditions, the buoyancy of the water is less than the spring tension, and the flip cover 7 is closed. When the anti-buoyancy water level exceeds the warning line, the buoyancy of the water is greater than the spring tension, the flip cover 7 is opened, and water from outside the basement flows into the water collection well 1. The water pump in the water collection well 1 is automatically turned on to pump water and reduce the water pressure. After the water pressure is reduced, the spring tension is greater than the buoyancy of the water, and the cover is closed. By setting up the water collection well 1 and the inner well 5, the impact of water pressure on the underground garage can be effectively reduced.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
