Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, in particular to a water stop device for water conservancy project construction. Background Art

[0002] The existing patent (Publication No.: CN221760620U) proposes a water stop device for water conservancy project construction, including a support frame and a closed frame. The support frame is fixed on the ground, and the closed frame is fixed in the river. The closed frame is C-shaped and open upward. An elevating device is arranged at the upper end of the support frame, a water retaining plate is fixed at the lower end of the elevating device, and a plurality of spoiler plates are fixed at the front end of the water retaining plate and are distributed at intervals left and right. The shape of the water retaining plate corresponds to the shape of the closed frame. However, when this device "the rotating disk rotates to drive the steel wire rope to rotate, and then drives the water retaining plate to rise or fall" to perform the water stop operation and the opening operation through the rise and fall of the water retaining plate, it is necessary to reserve enough space for the movement of the water retaining plate in the longitudinal position, so that the height of this device is relatively high, resulting in a relatively high overall center of gravity of this device and affecting the overall stability of this device. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the utility model provides a water stop device for water conservancy project construction, which can reduce the resistance when water flows through, ensure the water flow rate when water flows through, also reduce the resistance of the main water stop frame when water flows through the main water stop frame, increase the service life of this device, and has better stability.

[0004] The purpose of the utility model is realized through the following technical solutions:

[0005] A water stop device for water conservancy project construction includes a main water stop frame, an upper protective cover, a positioning plate, a measuring lifting hydraulic cylinder, a split water stop plate, a transverse driving frame, a displacement driving hydraulic cylinder, and a displacement driving disk. The main water stop frame has an internal partition platform, and the internal partition platform divides the interior of the main water stop frame into each water stop plate connection groove. The split water stop plate is adapted to the water stop plate connection groove, and the split water stop plate is connected to the water stop plate connection groove and rotates inside the water stop plate connection groove. The top of the main water stop frame has a hydraulic cylinder installation platform and a positioning column connection hole. The hydraulic cylinder installation platform is in the middle position, and the position of the positioning column connection hole corresponds to the position of the split water stop plate. A cross key installation chute is arranged on the side of the positioning column connection hole. The middle part of the split water stop plate has a middle strengthening column, the top of the middle strengthening column has a cross key positioning groove, and the top of the cross key positioning groove has a water stop plate positioning column.

[0006] The bottom of the water stop plate positioning column is rotatably connected to the positioning column connection hole. The surface of the positioning plate has a longitudinal positioning chute, and the position of the longitudinal positioning chute corresponds to the position of the water stop plate positioning column. The longitudinal positioning chute slides outside the water stop plate positioning column. The bottom of the positioning plate has a positioning cross key, and the position of the positioning cross key corresponds to the position of the longitudinal positioning chute. The positioning cross key is adapted to the cross key installation chute and the cross key positioning groove, and the positioning cross key is sequentially connected to the cross key installation chute and the cross key positioning groove.

[0007] The positioning cross key slides inside the cross key installation chute, and the positioning cross key is inserted into the cross key positioning groove. Both sides of the main water stop frame are fixedly connected with measuring lifting hydraulic cylinders, and the hydraulic rods of the measuring lifting hydraulic cylinders are fixedly connected with the positioning plate. The top of the water stop plate positioning column is fixedly connected with a displacement driving disc, and the top of the displacement driving disc has a displacement driving slider. Beneficial effects

[0008] 1. When the present utility model conducts water stop operation in water conservancy project construction, the horizontal driving frame is driven by the displacement driving hydraulic cylinder to move left and right. When the positioning cross key is at the right extreme position, the split water stop plates are arranged in a horizontal straight line and parallel to the main water stop frame to complete the water stop operation. When the positioning cross key is at the left extreme position, the split water stop plates are arranged in a vertical straight line perpendicular to the main water stop frame, and water can flow through freely. The mechanisms such as the displacement driving hydraulic cylinder and the horizontal driving frame that control the opening and closing of the split water stop plates only have a relatively large horizontal length and a relatively small vertical length, thereby reducing the overall height of this device, having a lower overall center, better stability, and lower cost.

[0009] 2. In the present utility model, both the cross key installation chute and the cross key positioning groove are cross key grooves. With the cross key structure of the positioning cross key, when the positioning cross key is connected to the cross key positioning groove, it provides fixation for the split water stop plates, avoiding the rotational force received by the split water stop plates after running to the extreme position from being transmitted to power mechanisms such as the horizontal driving frame and the displacement driving disc, which affects the service life of the power mechanisms.

[0010] 3. The side of the split water stop plate of the present utility model is designed as an arc, and both sides of the inner dividing platform are designed with conical inclination angles, reducing the resistance received when water flows through, ensuring the flow rate when water flows through, and also reducing the resistance received by the main water stop frame when water flows through the main water stop frame, increasing the service life of this device.

[0011] 4. When the horizontal driving frame is at the left and right extreme positions, the displacement driving slider will be clamped on one side of the displacement driving groove. At this time, the split water stop plates are in a state parallel to the main water stop frame or in a state perpendicular to the main water stop frame, ensuring the accuracy during the opening and closing movement and facilitating the subsequent connection of the positioning cross key and the cross key positioning groove.
