[0027] like Figure 1 to Figure 5 As shown, an embodiment of the utility model proposes a concrete formwork for water conservancy and hydropower dam construction, including a base 1, an upper surface of the base 1 is provided with two vertical plates 2, the two vertical plates 2 are rotatably connected to rotating rods 3, the rotating rods 3 penetrate the vertical plates 2, one side of one of the vertical plates 2 is fixedly connected to a rotating motor 4, the main shaft of the rotating motor 4 is fixedly connected to the rotating rod 3 on the vertical plate 2, the opposite ends of the two rotating rods 3 are fixedly connected to a support plate 5, a bottom plate 6 is fixedly connected between the two support plates 5, the upper surface of the bottom plate 6 is fixedly connected to four support seats 7, the upper surfaces of the four support seats 7 are fixedly connected to a fixed plate 8, the four side surfaces of the fixed plate 8 are provided with sliding holes, the sliding holes are slidably connected to sliding rods 10, one end of the sliding rods 10 is fixedly connected to a baffle 11, and a driving component 9 is provided on the lower surface of the bottom plate 6, the driving component 9 is used to drive the baffle 11 to move, and the driving component 9 drives the baffle 11 to move The sliding rod 10 slides in the sliding hole and sticks to the four sides of the fixed plate 8 to form a molding cavity, and concrete is injected between the fixed plate 8 and the baffle 11. After the concrete solidifies, the rotating motor 4 drives the bottom plate 6 and the baffle 11 to rotate 180 degrees, so that the molding cavity formed by the fixed plate 8 and the baffle 11 faces downward. At this time, the driving component 9 drives the four baffles 11 to slide away from the fixed plate 8, so that the baffle 11 is separated from the concrete block. In addition, there is no support under the concrete block at this time. Under the action of gravity, the staff can remove the concrete block more conveniently. By setting a combined concrete template, when making concrete blocks, the baffle 11 and the fixed plate 8 are gathered together to form a concrete block template, and the concrete blocks are cast and made. After the production is completed, the composed template is first turned over, and then the various components of the template are separated, and separated from the concrete block at the same time, so as to facilitate the removal of the concrete block.

[0028] Specifically, both sides of the baffle 11 are inclined surfaces, and the inclined surfaces on adjacent baffles 11 contact each other. A square groove is provided on the side of the baffle 11 close to the fixed plate 8, and the height of the square groove is the same as the thickness of the fixed plate 8. When forming a concrete formwork, the baffle 11 is gathered with the fixed block, the baffle 11 is fitted with the fixed block, and the fixed block is fitted with the square groove on the baffle 11 to form a mosaic state. The inclined surfaces on both sides of the baffle 11 are fitted to reduce the gap and prevent concrete overflow.

[0029] Specifically, the driving assembly 9 includes four mounting plates 91, and the four mounting plates 91 are fixedly connected to the four baffles 11 respectively. One side of the mounting plates 91 is fixedly connected to a rack 92. The lower surface of the fixed plate 8 is rotatably connected to a gear 93. The four racks 92 are meshed with the gear 93. The four racks 92 are located at different horizontal heights. The thickness of the gear 93 is greater than the sum of the thicknesses of the four racks 92. The four racks 92 are arranged in an array. The lower surface of the base plate 6 is fixedly connected to a driving motor 94. The main shaft of the driving motor 94 is fixedly connected to the gear 93. When the baffle 11 is controlled to move, the gear 93 is driven to rotate by the driving motor 94. The gear 93 simultaneously drives the four racks 92 to move. The four racks 92 drive the baffles 11 to move simultaneously. When making concrete blocks close to the fixed plate 8 and detaching from the concrete blocks away from the fixed plate 8, there is no need to push the baffles 11 one by one, which is more convenient and quick.

[0030] Specifically, two vertical plates 2 are slidably connected to two vertical rods 12, four vertical rods 12 are fixedly connected to the base 1, and two springs 13 are fixedly connected between the two vertical plates 2 and the base 1. The springs 13 are sleeved on the outside of the vertical rods 12. When the concrete block is made, the forming cavity formed by the fixed plate 8 and the baffle plate 11 faces downward. After the baffle plate 11 is separated from the concrete block, the vertical plate 2 is pulled up, and the vertical plate 2 drives the template formed by the fixed plate 8 and the baffle plate 11 to move downward. All the springs 13 are stretched and stored. When the vertical plate 2 is released, the spring 13 pulls the vertical plate 2 and the fixed plate 8 and the baffle plate 11 to reset downward, forming a vibration to promote the separation of the concrete block from the fixed plate 8. By forming vibration, the inertia of the concrete block moving up and down promotes the separation of the concrete block, which is more labor-saving.

[0031] Specifically, one side of the base 1 is fixedly connected to the vertical plate 14, one side of the vertical plate 14 is fixedly connected to the vibration motor 15, the main shaft of the vibration motor 15 is fixedly connected to the cam 16, and the other rotating rod 3 is pressed on the outside of the cam 16. During vibration, the cam 16 is driven to rotate by the vibration motor 15, and the protrusion of the cam 16 pushes the rotating rod 3 to move upward. When the protrusion of the cam 16 is separated from the rotating rod 3, the fixed plate 8 and the baffle 11 move downward and reset under the action of gravity and the tension of the spring 13, forming vibration. The cam 16 rotates multiple circles to form continuous vibration, thereby improving the vibration effect and promoting the separation of the concrete block.

[0032] Specifically, the upper surface of the base 1 is fixedly connected to the support frame 17, and the side of the vertical plate 2 close to the support frame 17 is fixedly connected to the round rod 18. When the fixed plate 8 and the baffle plate 11 move downward to reset under the action of gravity and the tension of the spring 13, the round rod 18 hits the support frame 17, and the device is supported by the support frame 17 to prevent the rotating rod 3 from directly pressing on the cam 16 when pressed down, causing the main shaft of the vibration motor 15 to be skewed and deformed.

[0033] Working principle: the driving motor 94 drives the gear 93 to rotate, and the gear 93 drives the four racks 92 to move at the same time. The four racks 92 drive the baffles 11 to move at the same time, close to the fixed plate 8, to form a molding cavity, and inject concrete between the fixed plate 8 and the baffles 11. After the concrete solidifies, the rotating motor 4 drives the bottom plate 6 and the baffle 11 to rotate 180 degrees, and the driving motor 94 drives the gear 93 to reverse, driving the four baffles 11 to slide away from the fixed plate 8, so that the baffles 11 are separated from the concrete block, and the vibration motor 15 drives the cam 16 to rotate, and the cam 16 protrusion pushes the rotating rod 3 to move upward. When the cam 16 protrusion is separated from the rotating rod 3, the fixed plate 8 and the baffle 11 move downward and reset under the action of gravity and the tension of the spring 13, forming vibration.
