Description

Technical Field

[0001] The invention relates to the technical field of underground garage waterproofing, and in particular to a waterproof drainage device for an underground garage. Background Art

[0002] In the construction of modern urban infrastructure, underground garages have become an indispensable part, widely distributed in various commercial buildings, residential areas and public facilities. Especially during the construction of underground garages, due to the imperfect waterproofing measures, the entrance of the underground garage passage has not been elevated. Therefore, whether it is during the construction process or on rainy days, the underground garage is very vulnerable to flooding.

[0003] In order to meet the temporary need of waterproofing during the construction of underground garages, the industry has continuously explored and applied various waterproofing devices and technical means. Among them, using water retaining boards to build a waterproof barrier is a common and widely used method.

[0004] The traditional water baffle is usually composed of brackets on both sides and a water baffle in the middle. In actual installation, the water baffle is first placed between the brackets on both sides, and then to ensure the sealing, at least one bolt is used at both ends of each water baffle to tighten it. In addition, when multiple water baffles are used together, they need to be tightened against each other with bolts to ensure the overall sealing.

[0005] However, this installation method has many disadvantages. The entire installation process is extremely cumbersome and complicated. From aligning the bolt holes, screwing in the bolts to adjusting the tightness, each link requires a lot of time and effort, which greatly slows down the construction progress. Moreover, when it is necessary to remove the water retaining plate, there are also many inconveniences. Since the bolts are tightly connected and there are many of them, the disassembly process is not only time-consuming and laborious, but also prone to damage and difficulty in removing the bolts.

[0006] It is worth noting that water retaining boards are often used to deal with sudden waterproof emergencies, and their installation and removal efficiency is required to be high. However, the cumbersome disassembly and assembly method of traditional water retaining boards obviously cannot meet the needs of efficient emergency response, which greatly reduces their flexibility in actual use.

[0007] In addition, due to its own structural characteristics, even after operations such as bolt tightening, the sealing effect of the traditional water retaining plate is still unsatisfactory. Summary of the invention

[0008] The present invention provides an underground garage waterproof drainage device, which solves the problem that the water retaining plate in the prior art has a long installation time and poor sealing performance.

[0009] The technical solution of the present invention is as follows: The underground garage waterproof drainage device comprises:

[0010] The column has two columns, the two columns are arranged opposite to each other, the column has a strip-shaped card slot, the strip-shaped card slots of the two columns are opposite to each other, and the strip-shaped card slot has a first sealing surface,

[0011] A water baffle, the water baffle is located between the two columns, and the left and right ends of the water baffle are respectively used to be clamped in the two strip-shaped slots,

[0012] The water baffle plate is arc-shaped and is a flexible plate. Both left and right ends of the water baffle plate have second sealing surfaces, and the second sealing surface is used to abut against the first sealing surface.

[0013] As a further technical solution,

[0014] The first sealing surface is an inwardly concave arc surface, and the second sealing surface is an outwardly convex arc surface.

[0015] As a further technical solution,

[0016] The column also has a guide support surface and a limit surface, wherein the guide support surface is opposite to the limit surface, one side of the first sealing surface is smoothly connected to the guide support surface, and the other side is connected to the limit surface.

[0017] The guide support surface, the first sealing surface and the limiting surface form the strip-shaped groove.

[0018] As a further technical solution, it also includes:

[0019] A sealing strip is arranged on the guide support surface.

[0020] As a further technical solution,

[0021] The sealing strip has an arc-shaped sealing surface, and the arc-shaped sealing surface faces the water baffle.

[0022] As a further technical solution, it also includes:

[0023] A top piece, wherein the top piece is arranged in the strip-shaped slot, the water baffle is located between the top piece and the sealing strip, and the top piece is used to tighten the water baffle.

[0024] As a further technical solution, the top member includes:

[0025] A shaft body, the shaft body is rotatably arranged in the strip-shaped slot,

[0026] A strip-shaped tightening protrusion is arranged on the shaft body. After the shaft body rotates, the strip-shaped tightening protrusion tightens the water baffle.

[0027] As a further technical solution,

[0028] The strip-shaped tightening protrusion is an elastic rubber block.

[0029] As a further technical solution,

[0030] There are a plurality of water baffles, and the plurality of water baffles are arranged in sequence in the strip-shaped slot.

[0031] The upper end of the water baffle plate is provided with a strip-shaped sealing groove, and the lower end of the water baffle plate is provided with a strip-shaped sealing block. The strip-shaped sealing block on one water baffle plate is used to be clamped in the strip-shaped sealing groove of another adjacent water baffle plate.

[0032] As a further technical solution, it also includes:

[0033] A pressing member, wherein the pressing member is arranged on the column, the pressing member is located above the uppermost water baffle plate, and the pressing member is used to press a plurality of the water baffle plates.

[0034] The working principle and beneficial effects of the present invention are:

[0035] In the present invention, two columns are fixedly mounted on two opposite walls of the garage passage, forming the basic frame structure of the entire underground garage waterproof drainage device, providing a stable support for the installation of subsequent components and the realization of waterproof function. The relatively arranged strip grooves on the columns define the installation position of the water retaining plate, and the first sealing surface at the bottom of the strip groove is one of the key elements to ensure the waterproof effect.

[0036] When facing the need for waterproofing of underground garages, you only need to insert the curved flexible water retaining plate into the corresponding strip slot to complete the basic installation operation. This installation method is simple and convenient, and the requirements for installation accuracy are relatively loose, and it can adapt to a certain degree of construction errors. In actual use, the outer curved surface of the water retaining plate serves as the water-facing surface. When it is subjected to water flow pressure or external force, the water retaining plate will gradually transition from its original curved state to a nearly straight state. During this deformation process, the second sealing surfaces at both ends of the water retaining plate will naturally approach and tightly abut the first sealing surface, thereby automatically forming a good sealing condition, effectively preventing water from infiltrating into the garage from the junction between the column and the water retaining plate, and initially realizing the waterproof function.

[0037] In addition, when installing the water retaining plate, the water retaining plate can be actively squeezed and limited to the position where the second sealing surface contacts the first sealing surface, so as to establish a good initial sealing state and further enhance the reliability of waterproofing. Moreover, compared with the straight water retaining plate, the curved water retaining plate has advantages in mechanical properties and can withstand greater squeezing force. Whether it is the continuous impact of daily water flow or the unexpected external force squeezing that may be encountered, it is less likely to be damaged or deformed, ensuring that the device can play a long-term and stable waterproofing role in the complex and changeable underground garage environment.

DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0051] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0052] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] like Figures 1 to 10As shown, the present invention proposes an underground garage waterproof drainage device, including: a column 1 and a water baffle 2, the column 1 has two, the two columns 1 are arranged opposite to each other, the column 1 has a strip groove 11, the strip grooves 11 of the two columns 1 are opposite to each other, the strip groove 11 has a first sealing surface 12, the water baffle 2 is located between the two columns 1, the left and right ends of the water baffle 2 are respectively used to be clamped in the two strip grooves 11, the water baffle 2 is arc-shaped, the water baffle 2 is a flexible plate, and the left and right ends of the water baffle 2 have a second sealing surface 21, and the second sealing surface 21 is used to abut against the first sealing surface 12.

[0055] In this embodiment, Figure 1 and Fig.10 As shown, two columns 1 are fixedly mounted on two opposite walls of the garage passage 7, forming the basic frame structure of the entire underground garage waterproof drainage device, providing a stable support for the installation of subsequent components and the realization of waterproof functions. The bar grooves 11 arranged relatively on the columns 1 define the installation position of the water retaining plate 2, and the first sealing surface 12 at the bottom of the bar grooves 11 is one of the key elements to ensure the waterproof effect.

[0056] When facing the need for waterproofing of underground garages, the basic installation operation can be completed by simply inserting the curved flexible water retaining plate 2 into the corresponding strip-shaped card slot 11. This installation method is simple and convenient, and the requirements for installation accuracy are relatively loose, and it can adapt to a certain degree of construction error. In actual use, the outer curved surface of the water retaining plate 2 serves as the water-facing surface. When subjected to water flow pressure or external force, the water retaining plate 2 will gradually transition from its original curved state to a nearly straight state. During this deformation process, the second sealing surfaces 21 at both ends of the water retaining plate 2 will naturally approach and tightly abut the first sealing surface 12, thereby automatically forming a good sealing condition, effectively preventing water from penetrating into the garage from the junction between the column 1 and the water retaining plate 2, and preliminarily realizing the waterproof function.

[0057] In addition, when installing the water baffle 2, the water baffle 2 can be actively squeezed and limited to the position where the second sealing surface 21 contacts the first sealing surface 12, so as to establish a good initial sealing state and further enhance the reliability of waterproofing. Moreover, compared with the straight water baffle, the curved water baffle 2 has advantages in mechanical properties and can withstand greater squeezing force. Whether it is the continuous impact of daily water flow or the unexpected external force squeezing that may be encountered, it is less likely to be damaged or deformed, ensuring that the device can play a long-term and stable waterproofing role in the complex and changeable underground garage environment.

[0058] Furthermore, the first sealing surface 12 is an inwardly concave arc surface, and the second sealing surface 21 is an outwardly convex arc surface.

[0059] In this embodiment, Figure 6As shown, the first sealing surface 12 is designed as an inwardly concave arc surface, and the second sealing surface 21 is designed as an outwardly convex arc surface. Such a design optimizes the sealing structure and significantly improves the waterproof effect.

[0060] When the water retaining plate 2 changes shape due to external force, a tighter contact with a larger fitting area can be achieved between the convex second sealing surface 21 and the concave first sealing surface 12. Compared with a flat sealing surface, this arc-shaped surface matching method can more evenly disperse the pressure exerted by the water flow and other external forces, so that the sealing surface can maintain a good and stable contact state under various stress conditions, greatly reducing the risk of leakage caused by gaps due to excessive local pressure.

[0061] Even if the underground garage encounters complex working conditions such as large water flow impact and frequent water level changes, the mutual adaptation of the arc-shaped sealing surfaces can still ensure the tightness of the seal and maintain a stable and reliable waterproof effect, effectively ensuring that the interior of the garage is always in a dry environment and avoids intrusion by external water flow.

[0062] Furthermore, the column 1 also has a guide support surface 13 and a limit surface 14, the guide support surface 13 is opposite to the limit surface 14, one side of the first sealing surface 12 is smoothly connected to the guide support surface 13, and the other side is connected to the limit surface 14, and the guide support surface 13, the first sealing surface 12 and the limit surface 14 form a strip groove 11.

[0063] In this embodiment, Figure 6 As shown, when the water retaining plate 2 is in a natural state, a part of its two ends can be in close contact with the guide support surface 13 to form a preliminary sealing state, which lays a good foundation for the subsequent overall waterproof function. When the water retaining plate 2 transitions from an arc state to a nearly straight state when encountering water flow impact or external force extrusion, the guide support surface 13 plays a key guiding role. It can follow the movement trend of the two ends of the water retaining plate 2 and accurately guide it to move in the direction close to the first sealing surface 12, ensuring that the whole process is smooth and orderly.

[0064] It is particularly worth mentioning that one side of the first sealing surface 12 is smoothly connected to the guide support surface 13. This smooth transition design is very clever, so that the second sealing surfaces 21 at both ends of the water retaining plate 2 can smoothly and unimpededly transition to a state of close contact with the first sealing surface 12 during the movement. Whether the water retaining plate 2 changes shape due to the slow action of daily water flow or in the case of sudden large water flow impact, it can rely on such structural characteristics to maintain good sealing at all times, effectively prevent water from leaking into the garage from the connection between the water retaining plate 2 and the column 1, ensure that the interior of the underground garage is always in a relatively dry environment, and allow the entire waterproof drainage device to function reliably in complex and changeable actual working conditions.

[0065] Furthermore, it also includes a sealing strip 3 , which is arranged on the guide support surface 13 .

[0066] In this embodiment, Figure 5 and Figure 6 As shown, when the water retaining plate 2 is in a natural state, the sealing strip 3 can enhance the initial sealing effect. When the water retaining plate 2 transitions to a nearly straight state due to external force, the sealing strip 3 will also adaptively change the contact state with the water retaining plate 2 as the water retaining plate 2 moves, and continue to play a filling and sealing role, thereby preventing moisture from penetrating into the garage through this easily overlooked weak link, ensuring that the entire waterproof drainage device can maintain a high standard of waterproof performance under various complex working conditions, providing reliable moisture-proof protection for facilities, vehicles, etc. in the garage, and effectively responding to potential threats such as water accumulation and water seepage that underground garages face for a long time.

[0067] Furthermore, the sealing strip 3 has an arcuate sealing surface 31 , and the arcuate sealing surface 31 faces the water retaining plate 2 .

[0068] In this embodiment, the sealing strip 3 has an arc-shaped sealing surface 31 facing the water retaining plate 2. This unique structural feature makes it more compatible with the entire waterproof device and plays a key role in improving the sealing effect.

[0069] Whether the water baffle 2 is in a natural arc state or in the process of transitioning to a nearly straight state due to external force, the arc-shaped sealing surface 31 can fit tightly with the arc-shaped surface of the water baffle 2. Due to its own arc shape, it can better adapt to the shape changes of the water baffle 2. No matter how the curvature of the water baffle 2 changes, the arc-shaped sealing surface 31 can automatically and accurately adjust the fitting angle and strength as it deforms, and always maintain the sealing state between the water baffle 2 and the water baffle 2 at the best level.

[0070] Compared with flat sealing strips, the design of this arc-shaped sealing surface 31 avoids problems such as local detachment and poor sealing during the dynamic changes of the water baffle 2. When facing complex situations such as slight expansion and contraction of components caused by temperature and humidity changes in the underground garage environment, and impact of water flows of different intensities, it can still rely on its good adaptability to the water baffle 2 to ensure that the sealing effect between the two is not affected, minimize the risk of leakage due to environmental factors or external forces, ensure the long-term maintenance of an ideal dry environment in the garage, and further improve the reliability and stability of the entire device in terms of waterproofing.

[0071] Furthermore, it also includes a top piece 4, which is arranged in the strip-shaped slot 11, and the water baffle plate 2 is located between the top piece 4 and the sealing strip 3, and the top piece 4 is used to tighten the water baffle plate 2.

[0072] In this embodiment, the top member 4 continuously applies a stable pressing force to the water retaining plate 2, so that the water retaining plate 2 can always maintain a tight fit with the first sealing surface 12 and the sealing strip 3 under various complex working conditions, thereby avoiding gaps caused by external forces from destroying the overall sealing.

[0073] Furthermore, the push piece 4 includes a shaft body 41 rotatably disposed in the strip-shaped slot 11 , and a strip-shaped tightening protrusion 42 is disposed on the shaft body 41 . After the shaft body 41 rotates, the strip-shaped tightening protrusion 42 tightens the water retaining plate 2 .

[0074] In this embodiment, Figure 6 As shown, after the water baffle 2 is installed, the strip-shaped tightening protrusion 42 can be ensured to tighten the water baffle 2 by rotating the shaft 41, which is simple and fast to operate compared with the existing screw tightening method.

[0075] Furthermore, the strip-shaped tightening protrusion 42 is an elastic rubber block.

[0076] In this embodiment, the strip-shaped tightening protrusion 42 is set as an elastic rubber block. This design brings significant advantages to the entire waterproof drainage device in two key aspects: perfect sealing and external force buffering, and further improves the waterproof performance and environmental adaptability of the device.

[0077] From the perspective of sealing effect, rubber itself has excellent elastic deformation ability. When the strip-shaped tightening protrusion 42 presses against the water retaining plate 2, it can adaptively deform according to the tiny irregular shapes that may exist on the surface of the water retaining plate 2, so as to more closely fit the actual contour of the water retaining plate 2, accurately fill those extremely tiny gaps that are easily overlooked under normal circumstances, further optimize the sealing effect after tightening, and minimize the possibility of water leakage from these tiny places, making the sealing of the entire waterproof structure more rigorous and reliable.

[0078] Furthermore, there are several water baffle plates 2, which are arranged in sequence in the strip groove 11. The upper end of the water baffle plate 2 has a strip sealing groove 22, and the lower end of the water baffle plate 2 has a strip sealing block 23. The strip sealing block 23 on one water baffle plate 2 is used to be clamped in the strip sealing groove 22 of another adjacent water baffle plate 2.

[0079] In this embodiment, adjacent water baffles 2 are mutually clamped by the strip sealing slots 22 at the upper end and the strip sealing blocks 23 at the lower end, thus forming an extremely tight connection structure. This clamping method can effectively close the gaps that may appear between the water baffles 2, and completely avoid the hidden danger of water leakage from the joints of the water baffles 2. Compared with the sealing method that only relies on the sealing between the two ends of the water baffles 2 and the column 1, this clamping seal between the water baffles 2 adds multiple reliable lines of defense, making the entire waterproof structure more stable and reliable, further strengthening the dry environment protection in the garage, enabling it to calmly deal with various complex problems such as water accumulation and water seepage that may occur in the underground garage, and providing more powerful waterproof protection for the facilities and vehicles in the garage.

[0080] In addition, the existing fixation of several water baffles 2 is all done by screws, and the left and right ends of each water baffle 2 are fastened by at least one screw. Rotating the screw to fix during installation is particularly cumbersome and slow. The setting of the shaft body 41 and the strip-shaped tightening protrusion 42 in the present application greatly improves the fixing speed, that is, the strip-shaped tightening protrusion 42 can directly complete the common tightening of multiple water baffles 2 by rotating the shaft body 41 at a certain angle, thereby greatly reducing the operation time.

[0081] Furthermore, it also includes a pressing member 5 , which is arranged on the column 1 and located above the uppermost water baffle plate 2 . The pressing member 5 is used to press a plurality of water baffle plates 2 .

[0082] In this embodiment, the pressing member 5 can make the connection between the water retaining plates 2 tighter by applying downward pressure, so that they form a stable whole and work together to play a waterproof role, effectively avoiding the generation of gaps or misalignments between adjacent water retaining plates 2 due to external forces, and ensuring the integrity of the waterproof system composed of multiple layers of water retaining plates 2.

[0083] Furthermore, a mounting groove 15 is opened on one side of the column 1, and the mounting groove 15 has an open end. The clamping member 5 includes a rotating shaft 51, and the rotating shaft 51 is disassembled and set in the mounting groove 15. The protrusion 52 is set on the rotating shaft 51. After the rotating shaft 51 rotates, the protrusion 52 presses against the upper end of the uppermost water baffle 2.

[0084] In this embodiment, Figure 7As shown, the rotating shaft 51 is arranged in the installation groove 15 and installed through the open end. This design greatly facilitates the installation and removal of the clamping member 5 itself. When the clamping member 5 needs to be maintained or replaced, or the entire waterproof drainage device needs to be replaced to install a water retaining plate or deep inspection, the operator can easily take out or install the clamping member 5, and the operation process will not cause excessive interference to other components, which effectively improves the maintainability of the entire device and reduces the difficulty and cost of later maintenance, so that the device can stably and reliably perform the waterproof drainage function for a long time, and continuously create a dry and safe environment for the underground garage.

[0085] Furthermore, the water retaining plate 2 has an inner curved surface and an outer curved surface, the outer curved surface is the water-facing surface, and the inner curved surface is the water-receiving surface.

[0086] In this embodiment, the curved water-facing surface can reduce the concentrated impact force of the water flow on the water retaining plate 2, thereby preventing the water retaining plate 2 from being damaged or the sealing structure from failing due to excessive local force.

[0087] Furthermore, both the first sealing surface 12 and the second sealing surface 21 have a rubber sealing layer.

[0088] In this embodiment, a rubber sealing layer is provided on both the first sealing surface 12 and the second sealing surface 21. The rubber sealing layer significantly enhances the sealing effect of the entire waterproof structure due to its unique material properties, further improving the device's ability to resist water leakage.

[0089] Furthermore, the column 1 is provided with a fixing hole 6 , through which the column 1 is fixed.

[0090] In this embodiment, the fixing hole 6 provides convenience for installing the column 1 and is more in line with actual installation requirements.

[0091] Further, if Figure 2 As shown, a first swing rod is provided at the end of the shaft body 41, and the shaft body 41 can be easily rotated by swinging the first swing rod. There is a first limiting hole on the first swing rod, and a first pin is disassembled and arranged in the first limiting hole. There is a first socket on the column 1, and the shaft body 41 is limited by inserting the pin into the first socket, thereby preventing loosening when tightening the water retaining plate 2.

[0092] Further, if Figure 2 As shown, a second swing rod is provided at one end of the rotating shaft 51. The rotating shaft 51 can be easily rotated by swinging the second swing rod to complete the tightening of the water baffle 2. There is a second limiting hole on the second swing rod. A second pin is disassembled and arranged in the second limiting hole. A second socket is provided on the column 1. By inserting the second pin into the second socket, the rotating shaft 51 is limited, thereby preventing loosening when the water baffle 2 is tightened.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
