Description

Technical Field

[0001] This utility model relates to the field of seepage control technology, and in particular to a flexible water receiving tray for seepage control in hydropower stations. Background Technology

[0002] During the inspection of hydraulic structures such as corridors and powerhouses, water seepage is frequently discovered. This seepage problem is one of the key challenges that has long plagued the operation and maintenance of hydropower stations. Traditional methods for treating seepage in hydropower stations often use iron or rigid plastic water collection trays. While these trays can play a certain role in collecting water, they have significant technical limitations. First, the rigidity of the material makes them unsuitable for complex curved surfaces such as the arch and walls of hydropower station corridors. They are also difficult to fit tightly to uneven surfaces such as shotcrete-supported tunnels or concrete-cast tunnels, leading to water seepage from the gaps. Second, the fixing method is limited and has poor adaptability. It can usually only be fixed by welding or bolts. When installed on curved or irregular structures, it is not only difficult to construct, but stress concentration may also cause the water collection tray to deform or crack. Third, the size is fixed and difficult to cut, resulting in poor seepage prevention for different forms of seepage, such as crack seepage, concentrated leakage, and sheet-like seepage. Utility Model Content

[0022] like Figure 1-4As shown, a flexible water receiving tray includes a flexible tray body 1. The flexible tray body 1 has a circumferentially inclined enclosure 102 and a recessed portion 2 located in the center. The area between the enclosure 102 and the recessed portion 2 is a water receiving surface 101. The short side of the main support plate 201 is connected to the enclosure 102, and the long side is connected to the water receiving surface 101 through a ramp 202 and a drainage channel 203. The ramp 202 and the drainage channel 203 are arranged symmetrically with respect to the main support plate 201. Since the recessed portion 2 is located in the middle of the flexible tray body 1, with water receiving surfaces 101 on both sides, the enclosure 102 encloses the recessed portion 2 and the water receiving surface 101, allowing the main support plate 201 to be arranged longitudinally within the recessed portion 2. A drain hole 206 is provided near both ends of the longitudinal direction, and the drain hole 206 is connected to a drain connector 4. The water receiving surface 101 is inclined from the enclosure 102 towards the recessed portion 2, forming a preset slope to guide liquid into the recessed portion 2. The outer edge of the enclosure 102 is provided with an outwardly extending mounting plate 103. Mounting holes 104 are provided at each of the four corners of the mounting plate 103 for fixing the water receiving tray to the external structure. The flexible tray 1 is made of flexible materials such as silicone or PVC, which can be easily cut and shaped using tools such as scissors or cutters. It is suitable for complex environments such as walls, corridor arches, and walls of hydropower stations, effectively reducing installation gaps and improving installation flexibility and convenience. The mounting plate 103 is preferably a thin metal sheet with pre-set standardized openings, supporting independent drilling to adapt to various installation needs. The installation method is flexible, and it can be fixed with bolts or glued. A removable baffle 205 is provided on the drainage hole 206, covering the drainage hole 206 to close or open the drainage connector 4. It is convenient to cut with cutting tools, or it can be retained to close the drainage connector 4.

[0023] like Figure 3 , 4 As shown, the recessed portion 2 includes a main support plate 201, a ramp 202, a water inlet channel 203, and a water collection channel 204. The main support plate 201 is located at the bottom of the recessed portion 2 and serves as the main bearing surface for collecting seepage water. Its surface is lower than the water receiving surface 101 and its thickness is greater than the thickness of the water receiving surface 101. The ramp 202 connects the two sides of the main support plate 201 to guide the seepage water to flow smoothly from the surface of the flexible disc 1 to the main support plate 201. The water inlet channel 203 connects the ramp 202 and the water receiving surface 101 to further guide the water flow and ensure that the water flow smoothly transitions from the ramp 202 to the main support plate 201. The water inlet channel 203 is located below the ramp 202. The projected area of ​​the ramp 202 is smaller than that of the water inlet channel 203. Preferably, the protruding cross section of the ramp 202 is trapezoidal. An inward concave space is left between the ramp 202 and the water inlet channel 203 to form the water collection channel 204, which is used to temporarily store seepage water with a large volume of water. The recessed part 2 adopts a ramp 202, a water channel 203 and a baffle 205, which can effectively guide and collect the seepage liquid and improve the drainage efficiency. like Figure 1 , 3As shown in Figure 5, the flexible disk 1 is fixedly connected to the support frame 3. The preferred support frame 3 is a steel wire frame, which can be fixed on the upper or lower surface or material of the flexible disk 1 and fits the outline of the flexible disk 1. The fixed support bar 301 is a fixed steel wire, and the support bar 302 is a transverse support steel wire.

[0024] The wire frame includes two fixed wires, which are embedded or bonded in the main support plate 201 and extend longitudinally along its length; a number of transverse support wires are arranged transversely along the disc body in a direction perpendicular to the fixed wires, the middle section of the transverse support wires is fixedly cross-connected with the bottom of the fixed wires, the transverse support wires are fixedly connected to the main support plate 201, and extend from both sides through the water receiving plate and the enclosure 102 to the edge of the disc body.

[0025] The middle section of the transverse support wire has bends 303 on both sides. The bends 303 correspond to the positions of the slope 202, the drainage channel 203, and the water collection channel 204 in the recessed part 2 of the flexible disc 1. The bends 303 are adapted to the contours of the slope 202, the drainage channel 203, and the water collection channel 204. By setting a wire frame inside the flexible disc 1 and fixing the center of gravity with two fixed wires, the cross-fixing of the fixed wires and the transverse support wires, and the shape of the support wires, both strength and ease of shaping and cutting are achieved. like Figure 6 As shown, the drainage connector 4 includes a tapered pipe 401, the large end of which is connected to the drainage hole 206 of the main support plate 201. A connecting pipe 402 is connected to the small end of the tapered pipe 401. The connecting pipe 402 has a threaded groove 403 and a radially protruding connecting ring 404 on its outer periphery. The threaded groove 403 is located at the lower end of the connecting pipe 402, and the connecting ring 404 is located above the threaded groove 403 and fixedly connected to the connecting pipe 402. Several connecting holes 405 are formed on the connecting ring 404. The connection to the water outlet pipe is achieved through both threaded connection via the threaded groove 403 and rigid connection via the connecting ring 404 and connecting holes 405. The combined use of these two connection methods improves connection stability and increases robustness. Alternatively, either a separate threaded connection or a rigid connection can be used depending on the actual environment.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
