Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a cofferdam device used in water conservancy construction. Background Art

[0002] A cofferdam refers to a temporary retaining structure built for the construction of permanent water conservancy facilities during water conservancy project construction. It is used to enclose the periphery of a building and effectively prevent water from entering the construction site of the building.

[0003] Authorization announcement number CN216865208U discloses a water conservancy construction cofferdam device. This patented technology can install the mounting frame on the outside of the cofferdam body by lengthening the screw rod. The protective net at the bottom of the mounting frame can protect the outside of the cofferdam body, reduce the impact of mud or large stones in the water on the outside of the cofferdam body, and provide good protection for the cofferdam body, avoiding damage to the cofferdam body as much as possible. The cofferdam body can be installed through the mounting groove, and the gap between the bottom of the cofferdam body and the mounting groove can be reduced with the sealing gasket, playing a sealing role, and can avoid water from entering the cofferdam body through the bottom of the cofferdam body as much as possible, with good protection effect; however, in the water conservancy scheme, When a project is to build a cofferdam, threaded screws are used for blocking. This method is not only time-consuming and labor-intensive, but also inconvenient to operate. In addition, the threaded screws are easy to rust and difficult to remove. Some cofferdams are built using wire rope pulling devices. Because the wire rope is affected by external factors such as sun and rain, it is easy to corrode. External and internal corrosion is particularly prone to corrosion. Corrosion is particularly prone to occur in the ocean or industrially polluted atmosphere. It not only reduces the metal area of the wire rope and thus reduces the breaking strength, but also causes surface roughness and the development of cracks from it, which accelerates fatigue. Severe corrosion will also cause a decrease in the elasticity of the wire rope. Therefore, a cofferdam device used in water conservancy construction is needed to improve the above problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: Please refer to Figures 1 - 4 A cofferdam device used in water conservancy construction shown in the figure, which includes a main body 1, and a fully automatic opening and closing assembly 2 is fixedly connected to the top of the main body 1.

[0026] In this embodiment, referring to Figure 1 、 Figure 2 and Figure 3 shown in the figure, the main body 1 includes a loading bottom plate 101, a first movable pin rod 104 is arranged on the side of the loading bottom plate 101, a first retaining plate 105 is arranged on the side of the first movable pin rod 104, the fully automatic opening and closing assembly 2 includes a loading box 201, an electric control execution motor 202 is installed inside the loading box 201, a winding wheel 203 is fixedly connected to the output end of the electric control execution motor 202, a steel wire rope 204 is arranged inside the winding wheel 203, a receiving wheel 205 is arranged inside the loading box 201, the steel wire rope 204 is arranged on the top of the receiving wheel 205, a connecting chain 206 is fixedly connected to the side of the steel wire rope 204, a base 207 is fixedly connected to the side of the connecting chain 206, and a fixing seat 208 is fixedly connected to the side of the base 207. The electric control execution motor 202 is used to drive the winding wheel 203 to pull back the steel wire rope 204, and cooperate with the receiving wheel 205 to make its working efficiency higher and more labor-saving. The steel wire rope 204 pulls the first retaining plate 105 and the second retaining plate 108 to cooperate with the rotation of the first movable pin rod and the second movable pin rod 107, so that the cofferdam formed by the first retaining plate ① and the second retaining plate 108 stands up, and the opening and closing of the cofferdam are controlled automatically. Without direct human participation, the cofferdam device automatically operates according to a predetermined rule by using an automatic pulling and releasing mechanism.

[0027] It should be noted that there seems to be an error in the original text where "the first retaining plate ①" is mentioned. It should probably be "the second retaining plate 108" for consistency. This has been translated as accurately as possible based on the provided text.Among them, a layer of anti-rust lubricating grease is evenly coated on the surface of the wire rope 204. The wire rope 204 has undergone a galvanizing process. There are two loading boxes 201, electric control actuating motors 202, winding wheels 203, wire ropes 204, receiving wheels 205, connecting chains 206 and bases 207. A layer of anti-rust lubricating grease is evenly coated on the surface of the wire rope 204. Applying oil can isolate the air, thereby achieving the purpose of anti-rust and anti-corrosion. This is the beneficial effect brought by applying oil to the wire rope 204. Applying oil to the wire rope 204 can reduce friction and maintain the normal friction coefficient between the wire ropes 204. The galvanized wire rope 204 brings long-term economic value at low cost, improves the product life, and avoids corrosion by the natural environment. The galvanized surface can improve the durability during use or transportation. The price of electrolytic galvanizing is quite cheap, which minimizes the finished product cost, prevents high-temperature corrosion, and prevents the oxidation of the inner layer of the wire rope 204.

[0028] In this embodiment, referring to Figure 1 、 Figure 2 and Figure 4 As shown, a limiting plate 111 is fixedly connected to the top of the first enclosing plate 105. A soft pad 110 is fixedly connected to the side of the limiting plate 111. There are two soft pads 110 and limiting plates 111. The first enclosing plate 105 is fixedly connected to the fixed seat 208. There are two fixed seats 208. A second movable pin rod 107 is arranged on the side of the first enclosing plate 105. A second enclosing plate 108 is arranged on the side of the second movable pin rod 107. A first steel framework 106 is fixedly connected to the side of the first enclosing plate 105. A second steel framework 109 is fixedly connected to the side of the second enclosing plate 108. A loading plate 102 is fixedly connected to the top of the loading bottom plate 101. A heightening plate 103 is fixedly connected to the top of the loading plate 102. There are two loading plates 102 and heightening plates 103. The soft pad 110 can prevent the first enclosing plate 105 from damaging the limiting plate 111.

[0029] In this solution, when a cofferdam device used in water conservancy construction needs to build a cofferdam, the electric control actuating motor 202 can be driven to make the winding wheel 203 rotate, so that the winding wheel 203 winds the wire rope 204 therein. The wire rope 204 pulls the first enclosing plate 105 and the second enclosing plate 108 to cooperate with the rotation of the first movable pin rod 104 and the second movable pin rod 107 to erect the cofferdam composed of the first enclosing plate 105 and the second enclosing plate 108. The electric control actuating motor 202 has a self-locking ability to prevent the wire rope 204 from slipping when pulling.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
