Description

Technical Field

[0001] This utility model relates to the field of water supply device technology, and in particular to a water supply device for dam fill material in hydropower stations. Background Technology

[0002] In the construction of hydropower station dams, the quality of the dam fill material is directly related to the stability and safety of the entire dam. The compaction quality of the fill material is one of the key indicators, and the moisture content of the fill material plays a crucial role in the compaction effect. The appropriate moisture content can enable the fill material to achieve the best density during the compaction process, ensuring the structural strength and seepage prevention performance of the dam.

[0003] Traditional methods of adding water to fill material are relatively crude, mostly relying on manual sprinkling or simple sprinkler spraying. This method has many drawbacks. On the one hand, manual sprinkling makes it difficult to ensure the uniformity of water addition, which can easily lead to localized areas with excessively high or low moisture content. This results in inconsistent density of the fill material after compaction, thus affecting the overall stability of the dam. On the other hand, the coverage area of ​​simple sprinkler spraying is limited, and it is impossible to accurately control the amount of water added based on factors such as the properties of the fill material, the thickness of the paving, and climatic conditions. Therefore, a water addition device for hydropower station dam fill material was designed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a water supply device for dam filling material in hydropower stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water supply device for dam fill material in a hydropower station includes a base plate. Side plates are rotatably connected to the top of the base plate near both ends. An adjustment mechanism is provided at the bottom of each of the two side plates. The adjustment mechanism includes a vertical plate fixedly connected to the middle of the bottom of the side plate. Multiple rotating pipes are rotatably connected at equal intervals on one side of the vertical plate. A third nozzle is fixedly connected to the bottom of each rotating pipe. A stop bar is fixedly connected to the side of each rotating pipe away from the vertical plate. A U-shaped baffle is fixedly connected to the side of the side plate near the stop bar. An L-shaped plate is slidably connected to the inner side of the U-shaped baffle. Multiple inclined holes are equally spaced at the bottom of the L-shaped plate, and the inclination of the multiple inclined holes increases sequentially. An irregularly shaped hole is provided at the top of the L-shaped plate.

[0007] As a further embodiment of this utility model, the irregular hole includes a horizontal hole and an oblique hole, and the bottom of one end of the horizontal hole is connected to the top of the oblique hole.

[0008] As a further embodiment of this utility model, each side plate is fixedly connected to two ends of its bottom with a second connecting block, and the same second water supply pipe is fixedly connected between two second connecting blocks on the same side. Furthermore, multiple second nozzles are fixedly connected at equal intervals at the bottom of each second water supply pipe. By setting the second nozzles, water can be sprayed onto the area directly below the side plate.

[0009] As a further embodiment of this utility model, vertical plates are fixedly connected to the top of both side plates near the L-shaped plate, and each vertical plate has a straight hole at its top.

[0010] As a further embodiment of this utility model, a first connecting block is fixedly connected to both ends of the bottom of the base plate, a first water supply pipe is fixedly connected between the two first connecting blocks, and multiple first nozzles are fixedly connected at equal intervals at the bottom of the first water supply pipe.

[0011] As a further embodiment of this utility model, a T-shaped plate is fixedly connected to the top center of the base plate, and electric push rods are rotatably connected to both sides of the top of the T-shaped plate. Connecting parts are fixedly connected to the bottom of each of the two electric push rods, and sliding rods are fixedly connected to the bottom of each of the two connecting parts. The two ends of each sliding rod are slidably connected to adjacent straight holes and irregular holes, and protrusions are fixedly connected to the two ends of each sliding rod. Through the cooperation of the electric push rods and the sliding rods, the angle of the side plate is adjustable, and the angle of the rotating tube is also adjustable.

[0012] As a further embodiment of this utility model, both ends of the top of the base plate are fixedly connected to a fixing frame, and the top of both fixing frames are provided with fixing holes, so that the fixing frames can facilitate the movement of the device.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes technologies such as an electric push rod, a second nozzle on the side plate, a baffle, and an L-shaped plate to install the device at the front of a sprinkler truck. The extension and retraction of the electric push rod allows the side plate to change from vertical to horizontal, while multiple rotating tubes can also shift outwards. This allows the spraying range to be adjusted according to needs, effectively solving the problems of uneven spraying and limited spraying range mentioned in the background technology. Furthermore, it enables a secondary expansion of the spraying range, increasing its practicality and facilitating real-time adjustment as needed, thereby improving the efficiency of sprinkler work.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4 A water supply device for dam fill material in a hydropower station includes a base plate 1. Side plates 4 are rotatably connected to the top of the base plate 1 near both ends. Adjustment mechanisms are provided at the bottom of the two side plates 4. The adjustment mechanisms include a vertical plate 6 fixedly connected to the middle of the bottom of the side plate 4. Multiple rotating pipes 601 are rotatably connected at equal intervals on one side of the vertical plate 6. A third nozzle 602 is fixedly connected to the bottom of each rotating pipe 601. A stop bar 603 is fixedly connected to the side of each rotating pipe 601 away from the vertical plate 6. A U-shaped baffle 404 is fixedly connected to the side of the side plate 4 near the stop bar 603. An L-shaped plate 7 is slidably connected to the inner side of the U-shaped baffle 404. Multiple inclined holes 701 are equidistantly opened at the bottom of the L-shaped plate 7, and the inclination of the multiple inclined holes 701 increases sequentially. The setting of the inclined holes 701 allows the multiple rotating pipes 601 to tilt, and the offset angle of the rotating pipes 601 further away from the base plate 1 is larger. An irregular hole 702 is opened at the top of the L-shaped plate 7.

[0023] In this embodiment, the irregular hole 702 includes a horizontal hole and an oblique hole, and the bottom of one end of the horizontal hole is connected to the top of the oblique hole.

[0024] In this embodiment, each side plate 4 has a second connecting block 401 fixedly connected to both ends of its bottom. The same second water supply pipe 402 is fixedly connected between the two second connecting blocks 401 on the same side. Each second water supply pipe 402 has multiple second nozzles 403 fixedly connected at equal distances at its bottom. The second nozzles 403 can spray water directly below the side plate 4.

[0025] In this embodiment, vertical plates 5 are fixedly connected to the top of both side plates 4 near the L-shaped plate 7, and each vertical plate 5 has a straight hole 501 at its top.

[0026] In this embodiment, a first connecting block 101 is fixedly connected to both ends of the bottom of the base plate 1, and a first water supply pipe 102 is fixedly connected between the two first connecting blocks 101. A plurality of first nozzles 103 are fixedly connected at equal intervals at the bottom of the first water supply pipe 102. By setting the first nozzles 103, spraying can be achieved directly below the sprinkler truck.

[0027] In this embodiment, a T-shaped plate 3 is fixedly connected to the top center of the base plate 1. Electric push rods 301 are rotatably connected to both sides of the top of the T-shaped plate 3. Connectors 303 are fixedly connected to the bottom of the two electric push rods 301. Sliding rods 302 are fixedly connected to the bottom of the two connecting rods 303. The two ends of each sliding rod 302 are slidably connected to the adjacent straight hole 501 and irregular hole 702. Protrusions are fixedly connected to the two ends of each sliding rod 302. By setting the sliding rods 302, when the side plate 4 becomes horizontal, and the electric push rods 301 continue to extend, the multiple rotating tubes 601 will shift the third nozzle 602 outward.

[0028] In this embodiment, a fixing bracket 2 is fixedly connected to both ends of the top of the base plate 1. The top of each fixing bracket 2 is provided with a fixing hole 201. The fixing bracket 2 facilitates the installation of the device.

[0029] Working principle: During installation, the device is fixedly installed at the front end of the water truck using the fixing bracket 2 and fixing hole 201. The second water pipe 402 and the first water pipe 102 are both connected to the water delivery pipe of the water truck. The second water pipe 402 and the first water pipe 102 are controlled by different control valves. The tops of multiple rotating pipes 601 are connected together by hoses, which are then connected to the water delivery pipe of the water truck. Electronic valves are installed on the hoses to control the working state of the third nozzle 602. When the water truck is adding water to the dam road at designated points and supplementing water to the dam surface, water is sprayed from the first nozzle 103 as the water truck moves, thus watering the dam road or dam surface. When it is necessary to expand the spraying range, the two electric push rods 301 are activated to extend, causing the side plates 4 on both sides to gradually descend from a vertical position to a horizontal position. In this state, because one end of the base plate 1 limits the side plate 4, the side plate 4 becomes horizontal and cannot deflect anymore. By supplying water to the second water pipe 402, the second nozzle 403 starts to work, thereby expanding the spraying range. When it is necessary to further expand the spraying range, the two electric push rods 301 continue to extend. Since the side plate 4 cannot rotate, the sliding rod 302 will slide in the straight hole 501 and also slide in the irregular hole 702. When it slides to the oblique hole of the irregular hole 702, the L-shaped plate 7 rises. Through the setting of multiple oblique holes 701, each rotating pipe 601 is offset away from the base plate 1, and the outermost rotating pipe 601 is offset more, so that multiple third nozzles 602 spray water towards the outside of the side plate 4, increasing the spraying range, thereby improving work efficiency and reducing the number of times the sprinkler truck moves back and forth.
