Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a novel movable cofferdam. 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. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be carried out within the cofferdam, foundation pits can be excavated, and buildings can be constructed. It is generally used in hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use. The height of the cofferdam is higher than the highest water level that may occur during the construction period.
[0003] In the related technology, there is a reinforced detachable water conservancy construction cofferdam with announcement number CN214574057U. This solution solves the problem that the current construction cofferdam is relatively complicated to install, resulting in the need to dismantle the construction cofferdam after the construction is completed, which is rather cumbersome and requires a lot of time to dismantle, wasting manpower and reducing work efficiency.

[0064] In the new movable cofferdam of the utility model embodiment, when in use, when impacted by water flow, the third plate body 3 approaches the direction of the first plate body 1, and the third plate body 3 will press the support plate 14 downward, so that the connecting column 21 moves toward the inside of the shell 22, and then compress the first spring 25, which can buffer and reduce the damage to the third plate body 3 caused by the impact, and prevent the third plate body 3 from deforming. At the same time, the second limit seats 20 are connected by the second spring 27. When the third plate body 3 is impacted by water flow, the impact force can be dispersed by the second spring 27 to reduce the local impact force. Because the first limit seat 19 is connected to the sliding block 28 through the third spring 29 and the second connecting plate 32, and the sliding block 28 slides in the second slide groove 31, when the third plate body 3 is impacted by water flow, the sliding block 28 can slide in the second slide groove 31 to disperse the impact force to the second plate body 2, thereby further increasing the buffering capacity.
[0065] In a specific embodiment, when in use, the first protrusion 4 and the second protrusion 5 can be plugged and connected with the first groove 6 and the second groove 7 correspondingly to realize the connection and fixation of one first plate body 1 with another first plate body 1, and the threaded rod 8 is driven to rotate by turning the knob, so that the first connecting plate 9 can be moved up and down. Since the fixing rod 12 is arranged at the bottom of the first connecting plate 9, the first connecting plate 9 can be moved and carried, and then the fixing rod 12 can be inserted into the underwater soil through the hole 13. When the third plate body 3 is impacted by the water flow, it approaches the direction of the first plate body 1, and the third plate body 3 will press the support plate 14 downward to make the connecting column 21 move toward the shell The first limit seat 20 is connected to the third plate body 3 by the second spring 27. When the third plate body 3 is impacted by the water flow, the impact force can be dispersed by the second spring 27 to reduce the local impact force. Because the first limit seat 19 is connected to the sliding block 28 by the third spring 29 and the second connecting plate 32, and the sliding block 28 slides in the second slide groove 31, when the third plate body 3 is impacted by the water flow, the sliding block 28 can slide in the second slide groove 31 to disperse the impact force to the second plate body 2, thereby further increasing the buffering capacity.
[0066] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
