Abstract

The application discloses a flexible water isolation door and a construction method thereof. The disclosed flexible water isolation door comprises a plurality of door beams arranged in sequence along the water level elevation direction, both ends of the door beam are slidably arranged in the corresponding gate pier slot, and a flexible door leaf is arranged between the adjacent door beams. The two sides of the flexible door leaf close to the gate pier are respectively provided with a first water stop part for being attached to the wall surface of the corresponding gate pier. The front side of the door beam close to the first water stop part is provided with a pressing sheet. One end of the pressing sheet is connected with the door beam, and the other end of the pressing sheet is a flexible free end. When the first water stop part is in the state of being attached to the wall surface of the gate pier, the flexible free end of the pressing sheet is in a curved or bent state, which is used for resisting the first water stop part and generating an elastic force for pressing the first water stop part to the wall surface of the gate pier. The above scheme can solve the problem that the current flexible water isolation door is affected by the application effect of the layered water taking due to the water leakage between the two sides of the flexible door leaf and the side wall of the gate pier.

Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering technology, and in particular to a flexible water-tight gate and its construction method. Background Technology

[0002] After a reservoir is built, the water flow velocity within the reservoir decreases, and most reservoirs exhibit temperature stratification, which is particularly pronounced in high-dam, large reservoirs. The impact of reservoirs on water temperature has become a hot topic of concern in river water environment protection. Currently, the main measures adopted to mitigate the adverse effects of downstream water temperature on the aquatic environment include: water conservancy ecological regulation and stratified water intake.

[0003] For stratified water intake in reservoirs, there are various forms of stratified water intake structures that have been built or are under construction both domestically and internationally. Through analysis and research on the inlet layout, working principle, operation mode, economy, advantages and disadvantages and applicable conditions of traditional stratified water intake measures such as multi-layer water intake, stacked beam gate, and water-proof curtain wall, as well as new stratified water intake measures, a more convenient flexible water-proof gate stratified water intake scheme is proposed.

[0004] The flexible water-tight gate disclosed in Chinese patent number "CN118326912A" is mainly composed of multiple main beams and flexible gate leaves. It achieves the folding and extension of the corresponding flexible gate leaves by sliding the main beams up and down in the water level direction, thereby completing the function of layered water intake.

[0005] However, existing flexible water-tight gates still have shortcomings. In particular, at the locations near the gate pier sidewalls on both sides of the flexible water-tight gate, since the flexible gate leaf and the gate pier sidewall are not an integral structure, water leakage is prone to occur between the flexible gate leaf and the gate pier sidewall, thereby reducing the application effect of the flexible water-tight gate for stratified water intake. Summary of the Invention

[0006] This invention discloses a flexible water-tight gate and its construction method to solve the problem that current flexible water-tight gates are prone to leakage between the two sides of the flexible gate leaf and the gate pier side wall, which affects the application effect of the flexible water-tight gate for layered water intake.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a flexible water-tight gate, comprising a plurality of gate beams arranged sequentially along the water level elevation direction, wherein the two ends of the gate beams are respectively slidably disposed in the corresponding gate pier gate slots, and a flexible gate leaf is disposed between adjacent gate beams; the flexible gate leaf is provided with a first water-stopping part for fitting against the corresponding gate pier wall on both sides near the gate pier, and a pressure plate is provided on the front side of the gate beam near the first water-stopping part, one end of the pressure plate is connected to the gate beam, and the other end of the pressure plate is an elastic free end; when the first water-stopping part is in a state of fitting against the gate pier wall, the elastic free end of the pressure plate is in a bent or folded state, used to abut against the first water-stopping part, and generate an elastic force to press the first water-stopping part against the gate pier wall.

[0009] Optionally, the gate pier is provided with a waterstop strip, which is located at the edge of the first waterstop part and extends vertically along the water level elevation direction; when the first waterstop part is in a state of being in contact with the gate pier wall, the edge of the first waterstop part and the free end of the pressure plate both abut against the waterstop strip.

[0010] Optionally, a gap is provided between the side of the waterstop strip facing the first waterstop portion and the gate pier for embedding the edge of the first waterstop portion and the free end of the pressure plate, and the height of the gap is less than the sum of the thickness of the first waterstop portion and the pressure plate.

[0011] Optionally, the gap is a flared structure, and the height of the gap gradually decreases from the gap inlet to the interior of the gap.

[0012] Optionally, the waterstop strip is a rubber rod, and the cross-sectional shape of the rubber rod is circular or elliptical; the rubber rod is fixedly installed on the wall of the gate pier and forms the gap by being tangent to the surface of the gate pier.

[0013] Optionally, the first water-stopping part is located on the water-facing side of the flexible gate leaf; the flexible gate leaf is also provided with a second water-stopping part on each side near the gate pier for fitting against the corresponding gate pier wall, and the second water-stopping part is located on the water-repellent side of the flexible gate leaf, and the first water-stopping part and the second water-stopping part form a "human" shaped water-stopping structure.

[0014] Optionally, guide components are provided at both ends of the front and rear sides of the gate beam facing the side walls of the gate pier slot, and the guide components are respectively used to cooperate with the limiting guide rails of the side walls of the gate pier slot for limiting movement.

[0015] Optionally, the guide assembly includes a guide portion, which is respectively disposed at both ends of the front and rear sides of the door beam, for limiting movement cooperation with the guide groove of the corresponding limiting guide rail; the guide assembly also includes two roller assemblies, which are respectively disposed at both ends of the rear side of the door beam, and the roller assemblies are adjacent to the guide portion, for rolling cooperation with the outer side wall of the limiting guide rail.

[0016] Optionally, a fastener is provided at one end of the pressure plate that is connected to the door beam, the pressure plate is detachably connected to the door beam through the fastener, and an adhesive material layer is provided between the pressure plate and the door beam.

[0017] Secondly, based on the aforementioned flexible water-resistant gate, the present invention also provides a construction method for a flexible water-resistant gate, which includes the following steps:

[0018] (1) A waterstop strip is attached to the wall of the gate pier near the gate pier slot. The waterstop strip extends vertically along the water level elevation direction and is used to abut against the edge of the first waterstop part and the elastic free end of the pressure plate.

[0019] (2) Adhesive material is attached to the front side of the gate beam near the end. First, one end of the pressure plate is bonded and fixed to the gate beam. Then, the pressure plate is fastened to the gate beam with fasteners. The other end of the pressure plate is bent so that the other end of the pressure plate generates elastic force to press the first water-stop part tightly against the gate pier wall and abut against the water-stop strip.

[0020] The technical solution adopted in this invention can achieve the following beneficial effects:

[0021] The flexible water-stop gate and its construction method disclosed in this invention, when the first water-stopping part is in contact with the gate pier wall, can generate an elastic force by bending or folding the elastic free end of the pressure plate, which can squeeze the first water-stopping part against the gate pier wall. This ensures that the first water-stopping part is tightly attached to the gate pier wall, which not only improves the water-stopping effect of the first water-stopping part, but also effectively solves the problem of the first water-stopping part detaching from the gate pier wall due to deformation and movement, thus ensuring the safe operation of the project. Therefore, this invention can effectively reduce the leakage of the flexible water-stop gate upstream and downstream, thereby avoiding the impact of leakage on the discharge temperature of the stratified water intake caused by existing flexible water-stop gates, significantly improving the application effect of the flexible water-stop gate, and ensuring the stability of the stratified water intake temperature and the safe operation of the project.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 4 As shown in the figure, this embodiment of the invention discloses a flexible water-tight gate. The disclosed flexible water-tight gate includes multiple gate beams 100 arranged sequentially along the water level elevation direction. The two ends of the gate beams 100 are respectively slidably disposed in the corresponding gate slots 220 of the gate pier. Flexible door leaves 110 are provided between adjacent gate beams 100. Thus, by moving two adjacent gate beams 100 upward or downward in opposite directions along the gate slots 220, the flexible door leaves 110 can be folded and opened, thereby realizing the water-tight and water-draining functions of the flexible water-tight gate. This part belongs to the existing structure and will not be described in detail in this embodiment. Typically, the flexible door leaves 110 adopt existing high-strength curtains. The top and bottom edges of the curtains are respectively fixedly disposed on the front sides of two adjacent gate beams 100, that is, the water-facing side of the gate beams 100.

[0032] The flexible gate leaf 110 is provided with a first water-stopping part 111 on each side near the gate pier for fitting against the corresponding gate pier wall 200. The gate beam 100 is provided with a pressure plate 120 on the front side near the first water-stopping part 111. One end of the pressure plate 120 is connected to the gate beam 100, and the other end of the pressure plate 120 is an elastic free end. When the first water-stopping part 111 is in a state of fitting against the gate pier wall 200, the elastic free end of the pressure plate 120 is bent or folded to abut against the first water-stopping part 111 and generate an elastic force to press the first water-stopping part 111 against the gate pier wall 200, thereby making the first water-stopping part 111 fit tightly against the gate pier wall 200. This can not only improve the water-stopping effect of the first water-stopping part 111, but also effectively solve the problem of the first water-stopping part 111 detaching from the gate pier wall 200 due to deformation and movement, thus ensuring the safe operation of the project.

[0033] Therefore, the flexible water-tight gate disclosed in this embodiment can effectively reduce the leakage upstream and downstream of the flexible water-tight gate, avoid the existing flexible water-tight gate from affecting the discharge temperature of stratified water intake due to leakage, significantly improve the application effect of the flexible water-tight gate, and ensure the stability of the stratified water intake temperature and the safe operation of the project.

[0034] As a specific configuration of the pressure plate 120, a fastener, such as a fastening bolt, can be provided at the end where the pressure plate 120 is connected to the door beam 100. This allows for a detachable connection between the pressure plate 120 and the door beam 100, facilitating the installation, disassembly, replacement, and maintenance of the pressure plate 120. Additionally, an adhesive material layer can be provided between the pressure plate 120 and the door beam 100. During installation, the pressure plate 120 can be pre-fixed using the adhesive material layer, facilitating the assembly of the fasteners. Furthermore, after the pressure plate 120 is installed, the adhesive material layer can also serve as a buffer layer, providing shock absorption.

[0035] The flexible water-resistant gate disclosed in this embodiment, such as... Figure 1 As shown, a waterstop strip 210 can also be installed on the gate pier. The waterstop strip 210 is located at the edge of the first waterstop part 111 and extends vertically along the water level elevation direction. When the first waterstop part 111 is in contact with the gate pier wall 200, the edge of the first waterstop part 111 and the free end of the pressure plate 120 both abut against the waterstop strip 210, thereby improving the waterstop effect of the first waterstop part 111 through the waterstop strip 210.

[0036] Preferably, a gap is provided between the side of the waterstop strip 210 facing the first waterstop part 111 and the gate pier, for the edge of the first waterstop part 111 and the free end of the pressure plate 120 to be embedded. The height of the gap is less than the sum of the thicknesses of the first waterstop part 111 and the pressure plate 120. Thus, the gap formed between the waterstop strip 210 and the gate pier wall 200 can ensure that the first waterstop part 111 is tightly fitted to the gate pier wall 200, and the pressure plate 120 can provide a uniform and consistent pressing force to the first waterstop part 111, ensuring the water-stopping effect of the entire side of the curtain. In particular, the pressure plate 120, in conjunction with the waterstop strip 210, can also ensure that the first waterstop part 111 can withstand the lateral water pressure well without deformation or displacement, keeping the first waterstop part 111 straight. This not only ensures the water-stopping effect, but also avoids the deformation and displacement of the first waterstop part 111 from affecting the orderly folding of the flexible door leaf 110, thereby ensuring the safe operation of the flexible water-stopping gate.

[0037] It is easy to understand that the above-mentioned gap is preferably designed as a flared structure, that is, the height of the gap gradually decreases from the gap inlet to the gap interior. Thus, the flared structure makes it easier for the free end of the pressure plate 120 and the first water-stop part 111 on the side of the flexible door leaf 110 to be embedded in the gap.

[0038] Meanwhile, the waterstop strip 210 can be a rubber rod, and the cross-sectional shape of the rubber rod is circular or elliptical. Thus, when the circular or elliptical rubber rod is fixedly installed on the gate pier wall 200, it can form a flared gap with the surface of the gate pier.

[0039] Typically, the first water-stopping part 111 is located on the water-facing side of the flexible gate leaf 110; preferably, the flexible gate leaf 110 is also provided with a second water-stopping part on each side near the gate pier for fitting against the corresponding gate pier wall 200, and the second water-stopping part is located on the water-repellent side of the flexible gate leaf 110, and the first water-stopping part 111 and the second water-stopping part form a "V"-shaped water-stopping structure; wherein, the first water-stopping part 111 and the second water-stopping part can be structural components made of rubber material to adapt to the folding and extension state changes of the flexible gate leaf 110.

[0040] Of course, the first water-stopping part 111 can also be set only on the water-facing side of the flexible door leaf 110, thus forming an L-shaped water-stopping structure. However, compared with the "human" shaped water-stopping structure, the L-shaped water-stopping structure is biased towards the upstream side. Under the action of the pressure difference between the upstream and downstream, the L-shaped water-stopping structure will move towards the downstream side, making it easier to deform and detach from the wall surface, and it is not easy to restore, thus affecting the water-stopping effect.

[0041] In the flexible water-tight gate disclosed in this embodiment, in order to achieve the sliding movement of the gate beam 100 along the gate slot 220 of the gate pier, as follows: Figure 1 , Figure 3 and Figure 4As shown, guide components 130 can be respectively installed at both ends of the front and rear sides of the gate beam 100 facing the gate slot 220. The guide components 130 are respectively used to cooperate with the limiting guide rails 221 on both sides of the gate slot 220 to limit movement. Thus, the gate beam 100 can be lifted and lowered in the water level elevation direction by the limiting movement of the guide components 130 along the limiting guide rails 221, thereby completing the extension and folding operation of the flexible gate leaf 110.

[0042] Specifically, the guide assembly 130 includes guide parts 131, which are respectively disposed at both ends of the front and rear sides of the door beam 100, that is, there are four guide parts 131, which are used to cooperate with the guide groove of the corresponding limit guide rail 221 for limited movement. Typically, the guide parts 131 adopt a square guide block structure and are fixed to the door beam 100 by fasteners such as bolts.

[0043] Meanwhile, the guide assembly 130 may also include two roller assemblies 140, which are respectively disposed at both ends of the rear or front side of the door beam 100, and the roller assemblies 140 are located near the guide portion 131 for rolling cooperation with the outer wall of the corresponding limiting guide rail 221.

[0044] Based on the above structure, the roller assembly 140 and the guide part 131 can form a two-part limiting structure with the limiting guide rail 221. The guide part 131 can avoid the collision between the gate beam 100 and the limiting guide rail 221, and the roller assembly 140 can avoid the collision between the gate beam 100 and the gate pier slot 220. Therefore, damage to the gate beam 100, the gate pier slot 220 and the limiting guide rail 221 can be avoided, which is conducive to safe operation. At the same time, the balance of the gate beam 100 can be ensured, which effectively reduces the risk of the gate beam 100 overturning or tilting. Preferably, the two roller assemblies 140 are respectively set at both ends of the rear side of the gate beam 100, that is, the roller assembly 140 is located on the opposite side of the pressure plate 120, thereby avoiding the influence between the roller assembly 140 and the pressure plate 120 and increasing the difficulty of assembly and installation.

[0045] Priority, such as Figure 3 As shown, the roller assembly 140 is located on the outside of the guide portion 131, that is, the roller assembly 140 is located on the side of the guide portion 131 near the end of the gate beam 100. Compared with the structure in which the roller assembly 140 is located on the inside of the guide portion 131 (the side of the guide portion 131 away from the end of the gate beam 100), it can better ensure that both the roller assembly 140 and the guide portion 131 are located in the position where the gate beam 100 is placed in the gate slot 220 of the gate pier. Moreover, the roller assembly 140 is far away from the first water stop portion 111, thereby avoiding the addition of the roller assembly 140 from affecting the tight fit between the first water stop portion 111 and the gate pier wall 200.

[0046] More preferably, a rolling element 132, such as a universal ball bearing or roller, can be provided on the side of the guide portion 131 facing away from the door beam 100. The rolling element 132 can effectively reduce the friction between the guide portion 131 and the limiting guide rail 221, thereby reducing the wear of the limiting guide rail 221 and ensuring the smooth operation of the door beam 100.

[0047] As one possible implementation of the roller assembly 140, the roller assembly 140 may include a mounting base and rollers. The mounting base is arranged perpendicular to the length direction of the gate beam 100, and the length of the mounting base is greater than the width of the gate beam 100. Both ends of the mounting base are located outside the gate beam 100. Two rollers are provided, which can better ensure the balance of the gate beam 100 during operation. The two rollers are respectively rotatably mounted at the two ends of the mounting base located outside the gate beam 100. This facilitates the installation of the rollers and, compared to other installation positions, avoids increasing the gap between the gate beam 100 and the side wall of the gate pier groove 220, which is beneficial for the tight fit between the first water-stopping part 111 and the gate pier wall surface 200. Preferably, as shown... Figure 3 As shown, the mounting base adopts an angle steel structure 150, which not only ensures the strength of the mounting structure and prevents deformation, but also protects the roller assembly 140.

[0048] Based on the flexible water-tight gate disclosed in this embodiment, this embodiment also discloses a construction method for the flexible water-tight gate, which may include the following steps:

[0049] (1) Clean the gate pier wall 200, and attach a waterstop strip 210 to the position of the gate pier wall 200 near the gate pier slot 220. The waterstop strip 210 extends vertically along the water level elevation direction and is used to abut against the edge of the first waterstop part 111 and the elastic free end of the pressure plate 120.

[0050] (2) Clean the surface of the gate beam 100, and adhere adhesive material to the front side of the gate beam 100 near the end. First, fix one end of the pressure plate 120 to the gate beam 100, and then fasten the pressure plate 120 to the gate beam 100 with fasteners. Bend the other end of the pressure plate 120 so that the other end of the pressure plate 120 generates elastic force to press the first water-stopping part 111 tightly against the gate pier wall 200 and abut against the water-stopping strip 210.

[0051] The above embodiments of the present invention focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0052] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
