Description

Technical Field

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

[0002] During water conservancy and hydropower construction, cofferdams are used to prevent soil slippage and maintain construction progress. However, cofferdams have some shortcomings and deficiencies, specifically requiring improvement as follows: 1. Conventional cofferdams are inconvenient to dismantle and store after use, and similarly, require assembly during installation, greatly increasing the difficulty of their use; 2. Cofferdams are generally made of metal, making transportation and handling a significant physical undertaking. Therefore, a moving mechanism could be incorporated to facilitate the movement and transport of the cofferdams. Consequently, we propose a reinforced cofferdam structure for water conservancy and hydropower construction. Utility Model Content

[0003] The main purpose of this utility model is to provide a reinforced structure for cofferdams in water conservancy and hydropower construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The reinforced structure of the cofferdam for water conservancy and hydropower construction includes a base plate. Three sets of receiving slots are equidistantly spaced at the upper end of the base plate, each containing a fixed support mechanism. A moving mechanism is fixedly connected to the left and right ends of the base plate. Connecting plates are fixedly connected to the rear left and rear right sides of the upper end of the base plate. A baffle is movably connected between two sets of connecting plates via hinges. Several sets of reinforcing plates are fixedly connected at equidistant distances to the front end of each baffle. A mounting lug is fixedly connected to the upper front end of the three sets of reinforcing plates on the outermost sides and the middle. A telescopic rod is movably inserted into each of the three mounting lugs. An extension plate is fixedly connected to the rear left and rear right ends of each baffle. Positioning holes are provided at the front left, rear left, front right, and rear right ends of the base plate. Several sets of friction plates are fixedly connected at equidistant distances to the lower end of the base plate.

[0006] Preferably, the support mechanism includes a set of second mounting ears, with a receiving rod movably connected in the middle of the set of second mounting ears via a hinge. The receiving rod has a threaded groove at its rear end, and a rotating screw is threadedly engaged with the receiving rod through the threaded groove. The rotating screw has a fixing hole at its rear end.

[0007] By adopting the above technical solution, the support mechanism is located inside the nearby receiving slot, which facilitates storage.

[0008] Preferably, the first mounting ear is fixedly connected to the inner wall of the receiving groove, and the first telescopic rod passes through the inside of the fixing hole.

[0009] By adopting the above technical solution: the first telescopic rod passes through the fixed hole, which can fix the angle between the receiving rod and the rotating screw, and support the baffle.

[0010] Preferably, the moving mechanism includes two sets of loop frames, one in front and one behind. Each set of loop frames has an interlacing block inside. The two sets of interlacing blocks are fixedly connected to a connecting rod. Several sets of moving rollers are evenly spaced at the lower end of the connecting rod. A second telescopic rod is movably arranged at the front left end and the rear left end of the connecting rod.

[0011] By adopting the above technical solution, the interpenetrating block is located inside the loop frame, which can limit the range of movement of the connecting rod.

[0012] Preferably, the two sets of the spiral frame are fixedly connected to the base plate, and the second telescopic rod is inserted and engaged with the nearby positioning hole.

[0013] By adopting the above technical solution, the No. 2 telescopic rod can be engaged with the positioning hole to fix the position of the connecting plate, making it convenient to store or lower the moving roller.

[0014] Preferably, several sets of friction plates are arranged at an angle, and the receiving groove corresponds to the position of the reinforcing plate.

[0015] By adopting the above technical solution, the inclination direction of the friction plate is opposite to the rotation direction of the baffle, which can increase the friction with the ground and reduce the possibility of the bottom plate slipping.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a support mechanism, the rotating screw on the support mechanism rotates, which can be used to adjust the overall length. At the same time, the fixing hole on the rotating screw interlocks with the first telescopic rod on the first mounting ear, which can be used to fix the angle of the support mechanism and support and fix the baffle. Conversely, the support mechanism can be stored in the nearby receiving slot. The operation is simple, the storage is convenient, and the difficulty of use is reduced.

[0018] 2. By setting up a moving mechanism, the second telescopic rod, which is movably connected to the connecting rod on the moving mechanism, is inserted and engaged with the positioning hole to fix the position of the connecting rod. The lower end of the connecting rod is equipped with a moving roller, which can facilitate the movement and transportation of the cofferdam. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] The reinforced structure of the cofferdam for water conservancy and hydropower construction includes a base plate 1. Three sets of receiving slots 2 are equally spaced on the upper end of the base plate 1. Each of the three sets of receiving slots 2 is fixedly connected to a support mechanism 3. The left and right ends of the base plate 1 are fixedly connected to a moving mechanism 4. The rear left and rear right ends of the upper end of the base plate 1 are fixedly connected to a connecting plate 5. A baffle 6 is movably connected between two sets of connecting plates 5 via a hinge. Several sets of reinforcing plates 7 are fixedly connected at equal distances to the front end of the baffle 6. The upper front end of the three sets of reinforcing plates 7 on the outermost sides and the middle is fixedly connected to a first mounting ear 8. A first telescopic rod 9 is movably installed on each of the three sets of first mounting ears 8. An extension plate 10 is fixedly connected to the rear left and rear right ends of the baffle 6. Positioning holes 11 are opened at the front left, rear left, front right, and rear right ends of the base plate 1. Several sets of friction plates 12 are fixedly connected at equal distances to the lower end of the base plate 1.

[0029] In this embodiment, the support mechanism 3 includes a set of second mounting ears 13. A receiving rod 14 is movably connected to the middle of the set of second mounting ears 13 via a hinge. A threaded groove 15 is opened at the rear end of the receiving rod 14. A rotating screw 16 is threadedly connected to the receiving rod 14 through the threaded groove 15. A fixing hole 17 is opened at the rear end of the rotating screw 16. The first mounting ear 8 is fixedly connected to the inner wall of the receiving groove 2. A first telescopic rod 9 passes through the inside of the fixing hole 17.

[0030] The above solution involves a rotating screw 16 threaded inside the receiving rod 14 on the support mechanism 3, which can be rotated to adjust the overall length. At the same time, the fixing hole 17 on the rotating screw 16 is inserted and engaged with the first telescopic rod 9 on the first mounting ear 8, thereby fixing the angle between the support mechanism 3 and the baffle 6 to block the soil. Conversely, the support mechanism 3 and the baffle 6 can be disassembled and stored.

[0031] In this embodiment, the moving mechanism 4 includes two sets of loop frames 41, one in front and one behind. Each set of loop frames 41 has an insert block 42 inserted inside. The two sets of insert blocks 42 are fixedly connected to a connecting rod 43. Several sets of moving rollers 44 are evenly arranged at the lower end of the connecting rod 43. A second telescopic rod 45 is movably arranged at the front left end and the rear left end of the connecting rod 43. The two sets of loop frames 41 are fixedly connected to the base plate 1. The second telescopic rod 45 is inserted and engaged with the nearby positioning hole 11. Several sets of friction plates 12 are inclined. The receiving groove 2 corresponds to the position of the reinforcing plate 7.

[0032] The above solution involves setting up a moving mechanism 4. The connecting rod 43 on the moving mechanism 4 can maintain a higher or lower position under the support of the second telescopic rod 45. Therefore, the lower moving roller 44 can be raised or lowered. Lowering the moving roller 44 makes it easy to move the cofferdam.

[0033] It should be noted that this utility model is a reinforcement structure for cofferdams in water conservancy and hydropower construction. During use, the base plate 1 is first brought into contact with the ground. An inclined friction plate 12 is fixedly connected to the lower end of the base plate 1, applying pressure to the base plate 1 so that the friction plate 12 embeds into the ground, increasing the friction between the base plate 1 and the ground. Then, the baffle 6 is rotated to detach it from the base plate 1, and the support mechanism 3 is rotated out of the adjacent receiving groove 2. Next, the rotating screw 16 inside the receiving rod 14 is rotated. The rotating screw 16 can extend and retract during rotation to change its length. Finally, the rear part of the rotating screw 16 is inserted into a straight-line distance... Inside the nearest mounting ear 8, the first telescopic rod 9 passes through the fixing hole 17, thus fixing the angle of the baffle 6. Conversely, separating the support mechanism 3 from the baffle 6 allows for storage. After use, when the cofferdam needs to be moved, the friction plate 12 at the lower end of the base plate 1 is pulled out of the soil, and the second telescopic rod 45 on the connecting rod 43 is pulled out from the nearby positioning hole 11. This allows the connecting rod 43 to be moved. Moving the connecting rod 43 downwards causes the second telescopic rod 45 to engage with the lower positioning hole 11, and at the same time, the moving roller 44 at the lower part of the connecting rod 43 contacts the ground, thus moving the cofferdam.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
