Description

Technical Field

[0001] This utility model relates to the field of construction cofferdam technology, and in particular to a cofferdam component for water conservancy and hydropower construction. Background Technology

[0002] In water conservancy and hydropower engineering construction, cofferdams are essential temporary water-retaining structures. Their function is to create waterless or low-water-level working conditions in the construction area, ensuring the smooth progress of key processes such as foundation construction and underwater structure installation. However, traditional cofferdams are mostly constructed of concrete structures or large steel formwork. Concrete cofferdams are difficult to dismantle, time-consuming, and cannot be reused. Although steel formwork can be reused, splicing and dismantling often require a large number of complex processes such as bolt connections and welding, resulting in low installation and dismantling efficiency, which in turn affects the convenience of steel formwork assembly and disassembly. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a cofferdam component for water conservancy and hydropower construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cofferdam component for water conservancy and hydropower construction, comprising a water-retaining steel plate, a slot provided on the side of the water-retaining steel plate, and a locking block fixedly connected to the other side of the water-retaining steel plate, the locking block being inserted into the slot on the side of an adjacent water-retaining steel plate, and symmetrically distributed fixing blocks provided on both sides of the front of the water-retaining steel plate, the adjacent water-retaining steel plates being fixed together by two close fixing blocks cooperating with a fixing component, the fixing component comprising a square box, a threaded hole provided on the inner wall of the square box, a screw threadedly connected to the inside of the threaded hole, a rotatable abutment provided at one end of the screw, and a rotating wheel fixedly connected to the other end of the screw, the abutment abutting against the adjacent fixing block, and the inner wall of the square box on the side away from the abutment abutting against the adjacent fixing block.

[0005] Preferably, the inner wall of the square box has a circular hole, and a guide rod is fixedly connected to the abutment plate, the guide rod being inserted into the circular hole.

[0006] Preferably, a handle sleeve is fixedly connected to the outer wall of the rotating wheel, and the handle sleeve is made of elastic rubber.

[0007] Preferably, a limiting rod is fixedly connected to the surface of the abutment, and a limiting groove is formed on the fixing block at the position corresponding to the limiting rod, with the limiting rod inserted into the limiting groove.

[0008] Preferably, a sealing gasket is provided inside the card slot, and the sealing gasket is tightly attached to the two sides of the card block.

[0009] Preferably, a support block is fixedly connected to the front edge of the water-blocking steel plate, and a support rod is inserted into the interior of two adjacent support blocks on the adjacent water-blocking steel plate. A handle is fixedly connected to one end of the support rod, and a stop bar is fixedly connected to the front edge of the water-blocking steel plate. The stop bar is located diagonally below the fixed block, and the handle is located between the fixed block and the stop bar.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the fixing components and fixing blocks cooperate to achieve convenient fixing and disassembly of the water-retaining steel plate. When it is necessary to fix adjacent water-retaining steel plates, place the square box between two close fixing blocks, so that the two fixing blocks are located inside the square box, and the inner wall of the square box away from the abutment plate abuts against one of the fixing blocks. Then, rotate the wheel at one end of the screw. Due to the threaded engagement between the screw and the threaded hole, the screw will move axially within the threaded hole, driving the rotatable abutment plate at one end to move closer to the other fixing block until the abutment plate abuts against the fixing block. Relying on the abutment plate and the square box... The clamping force of the inner wall of the box on the two fixing blocks ensures the stable fixation of adjacent water-retaining steel plates. When disassembly is required, simply rotate the wheel in the opposite direction to move the abutment away from the fixing block, and the fixing component can be easily removed to separate the adjacent water-retaining steel plates. This design eliminates the complex processes of bolt connection and welding used in traditional steel formwork, greatly improving the convenience of water-retaining steel plate assembly and disassembly, effectively shortening the time for cofferdam construction and dismantling, and thus improving the efficiency of the entire water conservancy and hydropower construction. Moreover, it is simple to operate, requiring no professional welding or other complex skills, reducing construction difficulty and labor costs.

[0012] 2. In this utility model, by inserting support rods into the interior of two adjacent support blocks on two adjacent water-blocking steel plates, the connection between the two fixed water-blocking steel plates can be made more stable, preventing the joint of the water-blocking steel plates from loosening due to water flow impact and causing leakage. At the same time, a stop bar is also fixedly connected to the front edge of the water-blocking steel plate, and the handle is located between the fixed block and the stop bar. The stop bar can play a certain blocking and limiting role for the handle, preventing the support rod from accidentally falling out of the support block. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a cofferdam component for water conservancy and hydropower construction, including a water-retaining steel plate 1. A slot 4 is provided on the side of the water-retaining steel plate 1, and a locking block 6 is fixedly connected to the other side of the water-retaining steel plate 1. The locking block 6 is inserted into the slot 4 on the side of the adjacent water-retaining steel plate 1. Symmetrically distributed fixing blocks 2 are provided on both sides of the front of the water-retaining steel plate 1. Adjacent water-retaining steel plates 1 are fixed together by two closely spaced fixing blocks 2 cooperating with a fixing component 3. The fixing component 3 includes a square box 301, with a threaded hole 302 on the inner wall of the square box 301. A screw 303 is threadedly connected inside the threaded hole 302. One end of the screw 303 is provided with a rotatable abutment 305, and the other end of the screw 303 is fixed... A rotating wheel 304 is fixedly connected to a stop plate 305, which abuts against the nearby fixed block 2. The inner wall of the square box 301 on the side away from the stop plate 305 abuts against the nearby fixed block 2. A round hole 13 is opened on the inner wall of the square box 301. A guide rod 12 is fixedly connected to the stop plate 305 and inserted into the round hole 13. A handle sleeve 14 is fixedly connected to the outer wall of the rotating wheel 304. The handle sleeve 14 is made of elastic rubber. A limit rod 11 is fixedly connected to the surface of the stop plate 305. A limit groove 15 is opened on the fixed block 2 at the position corresponding to the limit rod 11. The limit rod 11 is inserted into the limit groove 15. A sealing gasket 5 is provided inside the slot 4. The sealing gasket 5 is tightly attached to the two sides of the card block 6.

[0022] The beneficial effects achieved in this embodiment 1 are as follows: the fixing component 3 and the fixing block 2 cooperate to achieve convenient fixing and disassembly of the water-blocking steel plate 1. When it is necessary to fix adjacent water-blocking steel plates 1, the square box 301 is placed between two close fixing blocks 2, so that the two fixing blocks 2 are located inside the square box 301, and the inner wall of the square box 301 away from the abutment plate 305 abuts against one of the fixing blocks 2. Then, the rotating wheel 304 at one end of the screw 303 is rotated. Due to the threaded engagement between the screw 303 and the threaded hole 302, the screw 303 will move axially within the threaded hole 302, driving the abutment plate 305, which is rotatable at one end, to move. The plate moves closer to another fixed block 2 until the abutment 305 abuts against it. The clamping force between the abutment 305 and the inner wall of the square box 301 on the two fixed blocks 2 secures the adjacent water-retaining steel plates 1. This design eliminates the need for complex processes like bolt connections and welding used in traditional steel formwork, greatly improving the ease of assembly and disassembly of the water-retaining steel plates 1, effectively shortening the time for cofferdam construction and dismantling, and thus improving the overall efficiency of water conservancy and hydropower construction. Furthermore, it is simple to operate, requiring no specialized welding skills, reducing construction difficulty and labor costs. A handle made of elastic rubber is fixedly connected to the outer wall of the rotating wheel 304. Set 14, on the one hand, increases the friction of the operator's hands when rotating the wheel 304, making it easier to apply force, and on the other hand, improves the comfort of operation, reduces hand discomfort caused by prolonged operation, and improves the operating experience during construction. A limiting rod 11 is fixedly connected to the surface of the abutment plate 305, and a corresponding limiting groove 15 is opened on the fixing block 2. The limiting rod 11 is inserted into the limiting groove 15, further restricting the position of the abutment plate 305 relative to the fixing block 2, preventing displacement of the abutment plate 305 under the action of external forces such as water flow impact, enhancing the stability of the fixed connection between adjacent water-retaining steel plates 1, and ensuring the safety of the cofferdam during use. The structural stability of the structure is ensured by the cooperation between the guide rod 12 and the round hole 13, which allows the abutment plate 305 to move smoothly in a predetermined direction when driven by the screw 303, preventing the abutment plate 305 from rotating. This allows the guide rod 12 to be quickly aligned with the guide groove, improving the convenience of inserting the guide rod 12 into the guide groove. The sealing gasket 5 is set inside the slot 4, and the sealing gasket 5 is tightly attached to the two sides of the block 6, effectively filling the gap between the slot 4 and the block 6, preventing water from leaking from the splice of the water-retaining steel plate 1, improving the overall water-stopping performance of the cofferdam, and ensuring that the construction area can maintain waterless or low-water-level working conditions.

[0023] Example 2: As Figure 2 - Figure 3As shown, a support block 7 is fixedly connected to the front edge of the water-blocking steel plate 1. Support rods 8 are inserted into the interior of two adjacent support blocks 7 on adjacent water-blocking steel plates 1. A handle 9 is fixedly connected to one end of the support rod 8. A stop bar 10 is fixedly connected to the front edge of the water-blocking steel plate 1. The stop bar 10 is located diagonally below the fixed block 2. The handle 9 is located between the fixed block 2 and the stop bar 10.

[0024] The beneficial effects achieved in this embodiment 2 are as follows: by inserting support rods 8 into the interior of two adjacent support blocks 7 on two adjacent water-blocking steel plates 1, the connection between the two fixed water-blocking steel plates 1 can be made more stable, avoiding the situation where the joint of the water-blocking steel plates 1 becomes loose due to water flow impact and leakage occurs. At the same time, a stop rod 10 is also fixedly connected to the front edge of the water-blocking steel plate 1, and the handle 9 is located between the fixed block 2 and the stop rod 10. The stop rod 10 can play a certain blocking and limiting role for the handle 9, preventing the support rod 8 from accidentally coming off the support block 7.

[0025] The working principle of this embodiment is as follows: In use, firstly, a water-retaining steel plate 1 is placed at the predetermined cofferdam construction position. Then, another water-retaining steel plate 1 is taken, and the locking block 6 on one side of this water-retaining steel plate 1 is aligned with the locking groove 4 on the side of the already placed water-retaining steel plate 1. The locking block 6 is then inserted into the locking groove 4, completing the initial splicing and positioning between adjacent water-retaining steel plates 1. Next, the square box 301 in the fixing assembly 3 is placed between two fixing blocks 2 that are symmetrically distributed and close to each other on both sides of the front of the two adjacent water-retaining steel plates 1, ensuring that the inner wall of the square box 301 on the side away from the abutment plate 305 abuts against one of the fixing blocks 2. Afterwards, the operator holds the elastic rubber handle sleeve 14 on the outer wall of the rotating wheel 304 and rotates the rotating wheel 304. Due to the threaded connection between the screw 303 and the threaded hole 302 on the inner wall of the square box 301, the screw 303 will move axially within the threaded hole 302, causing the rotatable abutment 305 at one end to move closer to another fixed block 2. During this process, the guide rod 12 on the abutment 305 moves smoothly along the round hole 13 on the inner wall of the square box 301, ensuring the accuracy of the movement direction of the abutment 305, until the limiting rod 11 on the surface of the abutment 305 is inserted into the corresponding limiting groove 15 on the fixed block 2, and the abutment 305 and the fixed block 2 are tightly abutted. Relying on the clamping force of the abutment 305 and the inner wall of the square box 301 on the two fixed blocks 2, the adjacent water-blocking steel plates 1 are firmly fixed. After the two water-blocking steel plates 1 are fixed, several support rods 8 are then inserted into several sets of adjacent water-blocking plates. The two adjacent support blocks 7 on the front edge of the steel plate 1 allow the support rod 8 to provide lateral support. Since the stop rod 10 is located diagonally below the fixed block 2 and the handle 9 is located between the fixed block 2 and the stop rod 10, the stop rod 10 can block and limit the handle 9, preventing the support rod 8 from accidentally coming off the support block 7 and ensuring that the support rod 8 is always in an effective support state. Repeat the above operation to splice and fix multiple water-retaining steel plates 1 in sequence to complete the construction of the cofferdam. When the water conservancy and hydropower construction is completed and the cofferdam needs to be dismantled, first pull the support rod 8 out of the support block 7, then rotate the wheel 304 in the opposite direction to make the screw 303 drive the abutment plate 305 away from the fixed block 2, releasing the clamping effect of the fixing component 3 on the fixed block 2. Then remove the fixing component 3, and then pull out the locking block 6 of the adjacent water-retaining steel plate 1 from the locking groove 4 to separate the water-retaining steel plate 1. Repeat the operation in sequence to complete the dismantling of the cofferdam.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
