Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower engineering, and in particular to a flexible water-blocking door and a construction method thereof. Background Art

[0002] The construction of a reservoir will reduce water flow rates within it, leading to water temperature stratification in most reservoirs. This phenomenon is particularly pronounced in high-dam, large-scale reservoirs. The impact of reservoirs on water temperature has become a hot topic in river water environmental protection. Currently, the main measures used to mitigate the adverse effects of downstream water temperature on the aquatic environment include water conservancy ecological regulation and stratified water intake.

[0003] Regarding reservoir stratified water intake, at present, the stratified water intake buildings that have been built and are under construction at home and abroad are of various forms. Through analyzing and studying the water 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, stopcock, waterproof curtain wall and new stratified water intake measures, a more convenient flexible waterproof gate stratified water intake scheme is proposed.

[0004] For example, the flexible water barrier disclosed in the Chinese patent with patent number "CN118326912A" is mainly composed of multiple main beams and flexible door leaves. The main beams slide up and down in the direction of water level to achieve the folding and extension of the corresponding flexible door leaves, thereby completing the stratified water intake function.

[0005] However, the existing flexible watertight gates still have shortcomings. Among them, at the positions near the pier side walls on both sides of the flexible watertight gates, since the flexible gate leaves and the pier side walls are not an integrated structure, water leakage is likely to occur between the flexible gate leaves and the pier side walls, thereby reducing the application effect of the flexible watertight gates in stratified water intake. Summary of the Invention

[0006] The invention discloses a flexible watertight door and a construction method thereof, so as to solve the problem that the flexible watertight door is susceptible to water leakage between the two sides of the flexible door leaf and the gate pier side walls, thereby affecting the application effect of the flexible watertight door in stratified water intake.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions: In the first aspect, the present invention provides a flexible water-blocking gate, comprising a plurality of gate beams arranged in sequence along the water level elevation direction, the two ends of the gate beams being slidably set in the corresponding gate grooves of the piers, and flexible gate leaves being arranged between adjacent gate beams; the flexible gate leaves are respectively provided with first water-stopping portions for fitting with the corresponding pier walls on both sides close to the piers, and the front side of the gate beam close to the first water-stopping portion is provided with a pressing plate, one end of the pressing plate is connected to the gate beam, and the other end of the pressing plate is an elastic free end; when the first water-stopping portion is in a state of fitting with the pier wall, the elastic free end of the pressing plate is in a bent or folded state, for resisting the first water-stopping portion, and generating an elastic force to press the first water-stopping portion against the pier wall.

[0008] Optionally, the gate pier is provided with a water stop strip, which is located at the edge of the first water stop portion and extends vertically along the water level elevation direction; when the first water stop portion is in a state of being in contact with the gate pier wall, the edge of the first water stop portion and the free end of the pressing plate both press against the water stop strip.

[0009] Optionally, a gap is provided between the side of the water stop strip facing the first water stop portion and the gate pier for embedding the edge of the first water stop portion and the free end of the pressing sheet, and the height of the gap is less than the sum of the thicknesses of the first water stop portion and the pressing sheet.

[0010] Optionally, the gap is a flared structure, and the height of the gap gradually decreases from the gap entrance to the inside of the gap.

[0011] Optionally, the water stop strip is a rubber rod, and the cross-section of the rubber rod is circular or elliptical; the rubber rod is fixedly arranged on the wall surface of the pier and is tangent to the surface of the pier to form the gap.

[0012] Optionally, the first water stop is located on the water-facing side of the flexible gate leaf; the flexible gate leaf is also provided with a second water stop on both sides close to the gate pier for fitting with the corresponding gate pier wall, and the second water stop is located on the water-repellent side of the flexible gate leaf, and the first water stop and the second water stop form a "human" shaped water stop structure.

[0013] Optionally, guide components are respectively provided at both ends of the front side and rear side of the gate beam facing the side walls on both sides of the gate pier gate slot, and the guide components are respectively used to cooperate with the limiting guide rails on the side walls on both sides of the gate pier gate slot for limited movement.

[0014] Optionally, the guide assembly includes a guide portion, which is respectively arranged at the two ends of the front side and the rear side of the door beam, and is used to cooperate with the corresponding guide groove of the limiting guide rail for limiting movement; the guide assembly also includes two roller assemblies, which are respectively arranged at the two ends of the rear side of the door beam, and the roller assemblies are adjacent to the guide portion, and are used to roll with the outer side wall of the limiting guide rail.

[0015] Optionally, a fastener is provided at one end of the pressing plate connected to the door beam, the pressing plate is detachably connected to the door beam via the fastener, and a layer of adhesive material is provided between the pressing plate and the door beam.

[0016] In a second aspect, based on the above-mentioned flexible watertight door, the present invention further provides a flexible watertight door construction method, which comprises the following steps: (1) A water stop strip is attached to the gate pier wall near the gate pier slot, the water stop strip extending vertically along the water level elevation direction, and the water stop strip is used to abut against the edge of the first water stop portion and the elastic free end of the pressing sheet; (2) Adhere adhesive material to the front side surface of the door beam near the end, first adhere one end of the pressing plate to the door beam, then fasten the pressing plate to the door beam through fasteners, bend the other end of the pressing plate so that the other end of the pressing plate generates elastic force to press the first water stop portion tightly against the gate pier wall and against the water stop strip.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The technical solutions disclosed in various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 4 As shown, an embodiment of the present invention discloses a flexible watertight gate. The disclosed flexible watertight gate includes a plurality of gate beams 100 arranged in sequence along the water level elevation direction. The two ends of the gate beams 100 are respectively slidably set in the corresponding gate slots 220 of the pier, and a flexible gate leaf 110 is provided between adjacent gate beams 100, so that the flexible gate leaf 110 can be folded and opened by moving the two adjacent gate beams 100 upward or downward toward or away from each other along the gate slots 220, thereby realizing the water-isolating and water-draining functions of the flexible watertight gate. This part belongs to the existing structure and will not be described in detail in this embodiment. Usually, the flexible gate leaf 110 adopts an existing high-strength curtain, and the top and bottom edges of the curtain are respectively fixedly set on the front side surfaces of the two adjacent gate beams 100, that is, the side of the gate beam 100 facing the water.

[0022] Among them, the flexible door leaf 110 is respectively provided with a first water stop portion 111 on both sides close to the gate pier for fitting with the corresponding gate pier wall surface 200, and the door beam 100 is provided with a pressing plate 120 on the front side close to the first water stop portion 111, one end of the pressing plate 120 is connected to the door beam 100, and the other end of the pressing plate 120 is an elastic free end; when the first water stop portion 111 is in a state of fitting with the gate pier wall surface 200, the elastic free end of the pressing plate 120 is in a bent or folded state, which is used to resist the first water stop portion 111 and generate an elastic force to squeeze the first water stop portion 111 to the gate pier wall surface 200, so that the first water stop portion 111 is closely fitted with the gate pier wall surface 200, which can not only improve the water-stopping effect of the first water stop portion 111, but also effectively solve the problem of the first water stop portion 111 being separated from the gate pier wall surface 200 due to deformation and movement, thereby ensuring the safe operation of the project.

[0023] Therefore, the flexible watertight gate disclosed in this embodiment can effectively reduce the leakage upstream and downstream of the flexible watertight gate, avoid the existing flexible watertight gate affecting the downstream temperature of stratified water intake due to leakage, significantly improve the application effect of the flexible watertight gate, and ensure the stability of the stratified water intake temperature and the safe operation of the project.

[0024] As a specific setting method of the pressing plate 120, a fastener, such as a fastening bolt, can be provided at one end where the pressing plate 120 is connected to the door beam 100, so that a detachable connection between the pressing plate 120 and the door beam 100 is achieved through the fastener, which is convenient for the installation, disassembly, replacement and maintenance of the pressing plate 120; at the same time, a sticky material layer can also be provided between the pressing plate 120 and the door beam 100, so that when the pressing plate 120 is installed, the pressing plate 120 can be pre-fixed by the sticky material layer to facilitate the assembly of the fastener, and after the pressing plate 120 is installed, the sticky material layer can also serve as a buffer layer to play a shock-absorbing role.

[0025] The flexible watertight door disclosed in this embodiment, such as Figure 1 As shown, a water stop strip 210 can also be provided on the gate pier. The water stop strip 210 is located at the edge of the first water stop portion 111 and extends vertically along the water level elevation direction. When the first water stop portion 111 is in a state of being in contact with the gate pier wall 200, the edge of the first water stop portion 111 and the free end of the pressing sheet 120 both press against the water stop strip 210, thereby the water stop effect of the first water stop portion 111 can be better improved through the water stop strip 210.

[0026] Preferably, a gap is provided between the side of the water stop strip 210 facing the first water stop portion 111 and the gate pier, for embedding the edge of the first water stop portion 111 and the free end of the pressing plate 120, and the height of the gap is less than the sum of the thicknesses of the first water stop portion 111 and the pressing plate 120. Thus, the gap formed between the water stop strip 210 and the gate pier wall 200 can not only ensure that the first water stop portion 111 is tightly fitted to the gate pier wall 200, but also enable the pressing plate 120 to provide a uniform and consistent pressing force for the first water stop portion 111, thereby ensuring the water-stopping effect of the entire side of the curtain; in particular, the pressing plate 120 cooperates with the water stop strip 210 to enable the first water stop portion 111 to withstand lateral water pressure well without deformation and displacement, and keep the first water stop portion 111 straight, which not only ensures the water-stopping effect, but also avoids the deformation and displacement of the first water stop portion 111 affecting the orderly folding of the flexible door leaf 110, thereby ensuring the safe operation of the flexible watertight door.

[0027] 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 entrance to the inside of the gap, so that the flared structure can make the free end of the pressing plate 120 and the first water stop 111 on the side of the flexible door leaf 110 more easily embedded in the gap.

[0028] At the same time, the water stop strip 210 can be a rubber rod, and the cross-sectional shape of the rubber rod is circular or elliptical, so that when the circular or elliptical rubber rod is fixed to the pier wall 200, it can be tangent to the surface of the pier to form a gap of an expanded structure.

[0029] Typically, the first water stop 111 is located on the water-facing side of the flexible gate leaf 110; preferably, the flexible gate leaf 110 is further provided with a second water stop on both sides close to the gate pier for fitting with the corresponding gate pier wall 200, and the second water stop is located on the water-repellent side of the flexible gate leaf 110, and the first water stop 111 and the second water stop form a "human" shaped water stop structure; wherein, the first water stop 111 and the second water stop can be structural parts made of rubber material to adapt to the changes in the folding and extension states of the flexible gate leaf 110.

[0030] Of course, the first water stop portion 111 can also be provided only on the water-facing side of the flexible door leaf 110, that is, an L-shaped water stop structure is formed. However, compared with the "human" shaped water stop structure, the L-shaped water stop structure is biased towards the upstream side. Under the action of the upstream and downstream pressure difference, the L-shaped water stop structure will move toward the downstream side and is more likely to deform and detach from the wall, and it is not easy to recover, which affects the water stop effect.

[0031] In the flexible watertight door disclosed in this embodiment, in order to realize the sliding movement of the door beam 100 along the gate groove 220 of the gate pier, as shown in FIG. Figure 1 、 Figure 3 and Figure 4As shown, guide components 130 can be respectively provided at both ends of the front side and the rear side of the door beam 100 facing the side walls on both sides of the gate pier gate slot 220, and the guide components 130 are respectively used to cooperate with the limiting guide rails 221 on the side walls on both sides of the gate pier gate slot 220 for limiting movement, so that the door beam 100 can be lifted and lowered in the direction of the water level elevation through the limiting movement of the guide components 130 along the limiting guide rails 221, thereby completing the extension and folding operation of the flexible door leaf 110.

[0032] Specifically, the guide assembly 130 includes a guide portion 131, which is respectively arranged at the two ends of the front side and the rear side of the door beam 100, that is, the number of guide portions 131 is four, which is used to cooperate with the guide groove of the corresponding limiting guide rail 221 for limiting movement. Usually, the guide portion 131 adopts a square guide block structure and is fixed to the door beam 100 by fasteners such as bolts.

[0033] At the same time, the guide assembly 130 can also include two roller assemblies 140, which are respectively arranged at the two ends of the rear side or the front side of the door beam 100, and the roller assembly 140 is located near the guide part 131, for rolling cooperation with the outer side wall of the corresponding limiting guide rail 221.

[0034] 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 of the door beam 100 with the limiting guide rail 221, and the roller assembly 140 can avoid the collision of the door beam 100 with the gate pier gate slot 220; therefore, it can avoid damage to the door beam 100, the gate pier gate slot 220 and the limiting guide rail 221, which is conducive to safe operation, and can ensure the balance of the operation of the door beam 100, effectively reducing the risk of the door beam 100 flipping and tilting; preferably, the two roller assemblies 140 are respectively arranged at the two ends of the rear side surface of the door beam 100, that is, the roller assembly 140 is located on the other side opposite to the pressing plate 120, so as to avoid the influence between the roller assembly 140 and the pressing plate 120 and increase the difficulty of assembly and installation.

[0035] Preferentially, 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 close to the end of the door beam 100. Compared with the structure in which the roller assembly 140 is arranged on the inside of the guide portion 131 (the side of the guide portion 131 away from the end of the door beam 100), it can better ensure that the roller assembly 140 and the guide portion 131 are both located at the position where the door beam 100 is placed in the gate pier gate groove 220, and the roller assembly 140 is away from the first water stop portion 111, thereby avoiding the close fit between the first water stop portion 111 and the gate pier wall 200 due to the addition of the roller assembly 140.

[0036] More preferably, a rolling member 132, such as a universal ball or roller structure, can be provided on the side of the guide portion 131 facing away from the door beam 100, so that the friction between the guide portion 131 and the limiting guide rail 221 can be effectively reduced through the rolling member 132, that is, the wear of the limiting guide rail 221 can be reduced, and the smooth operation of the door beam 100 can be better ensured.

[0037] As an implementation method of the roller assembly 140, the roller assembly 140 may include a mounting seat and a roller, the mounting seat is arranged perpendicular to the length direction of the door beam 100, and the length of the mounting seat is greater than the width of the door beam 100, and both ends of the mounting seat are located outside the door beam 100; the number of rollers is two, which can better ensure the balance of the operation of the door beam 100, and the two rollers are rotatably arranged at the two ends of the mounting seat located outside the door beam 100, thereby facilitating the installation of the rollers and avoiding the increase in the gap between the door beam 100 and the side wall of the gate pier slot 220 compared to other installation positions, which is conducive to the close fit between the first water stop 111 and the gate pier wall 200; preferably, as Figure 3 As shown, the mounting seat adopts an angle steel structure 150 , which not only ensures the strength of the mounting structure and prevents deformation, but also plays a protective role for the roller assembly 140 .

[0038] Based on the flexible watertight door disclosed in this embodiment, this embodiment also discloses a flexible watertight door construction method, which may include the following steps: (1) Clean the gate pier wall 200, and adhere a water stop strip 210 to the gate pier wall 200 near the gate pier slot 220. The water stop strip 210 extends vertically along the water level elevation direction. The water stop strip 210 is used to abut against the edge of the first water stop portion 111 and the elastic free end of the pressing piece 120; (2) Clean the surface of the door beam 100, adhere the adhesive material to the front side of the door beam 100 near the end, first glue one end of the pressing plate 120 to the door beam 100, then fasten the pressing plate 120 to the door beam 100 with fasteners, bend the other end of the pressing plate 120 so that the other end of the pressing plate 120 generates an elastic force to press the first water stop portion 111 tightly against the gate pier wall 200 and against the water stop strip 210.

[0039] The above embodiments of the present invention focus on 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. Considering the simplicity of the text, they will not be repeated here.

[0040] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
