Description

Technical Field

[0001] The utility model relates to the technical field of diversion devices, in particular to a diversion device for gravity dam construction. Background Art

[0002] A gravity dam is a dam built of concrete or stone, which mainly relies on the deadweight of the dam body to maintain its own stability. The most common existing gravity dams are overflow gravity dams, which ensure the water level by overflowing due to rising water levels. For example, the patent with publication number CN216515426U discloses a diversion device for the construction of a concrete gravity dam in a water conservancy project, including a gravity dam body, an accelerated diversion module and an automatic flow adjustment module. A diversion flow groove is arranged on the lower right side of the gravity dam body, a cylinder is arranged on the inner wall of the middle part of the diversion flow groove, and an accelerated diversion hole is arranged at the center of the left end of the cylinder; the device can be The fixed baffle is driven to rise and fall by the adjusting screw, thereby adjusting the water flow in the diversion channel in a fixed manner. The sliding baffle moves down along the fixed guide rod due to gravity, and the buoy can automatically drive the sliding baffle to move up with the height of the water level. The higher the water level, the more the sliding baffle moves up, and the greater the water flow in the diversion channel. This prevents the problem of sudden water level increase and untimely drainage due to heavy rain, reduces the work intensity of employees, and improves safety. However, the water level height cannot be adjusted, only the fixed water level can be adjusted, and the water level may change at any time, resulting in poor adjustment ability of the overflow gravity dam.

[0003] To this end, the utility model provides a gravity dam construction diversion device. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figures 1 to 4The utility model provides a technical solution: a gravity dam construction diversion device, including a gravity dam 1, a gate 2 is opened on the gravity dam 1, one side of the gravity dam 1 is an inclined structure, a plurality of diversion grooves 4 are opened in the gravity dam 1, and a first baffle plate 8 and a plurality of second baffle plates 10 are slidably matched on the other side of the gravity dam 1, the second baffle plate 10 is in contact with the gravity dam 1, and the second baffle plate 10 corresponds to the diversion groove 4, and a plurality of limit blocks 9 are fixed on the gravity dam 1, and the limit blocks 9 correspond to the second baffle plates 10.

[0020] In this embodiment, a buffer block 11 is fixed at the bottom of the inclined structure. The buffer block 11 is a curved structure. Guide walls 3 are fixed on both sides of the inclined structure.

[0021] When water flows out of the gate 2, the higher water directly impacts the buffer block 11, and the buffer block 11 can buffer the water flow to prevent the water flow from directly impacting the base.

[0022] The guide groove 4 runs through the gravity dam 1, and a first slide groove 5 is opened in the gravity dam 1, and the first slide groove 5 corresponds to the first baffle 8. A second slide groove 6 is opened in the gravity dam 1, and the second slide groove 6 corresponds to the second baffle 10. A limit block 9 is fixed in the second slide groove 6, and multiple limit blocks 9 form a stepped structure up and down. A third slide groove 7 is opened on the side of the gravity dam 1 away from the inclined structure, and a slider is fixed on the second baffle 10, and the slider corresponds to the third slide groove 7.

[0023] Specifically, when the water level needs to be changed, the second baffle 10 is slid downward through the second slide groove 6 and the third slide groove 7. The second baffle 10 is pulled externally through a steel wire rope until the second baffle 10 is contacted by the corresponding limit block 9. The second baffle 10 can be limited to the guide groove 4, thereby controlling the water level.

[0024] In particular, the first baffle plate 8 can prevent the water flow from directly impacting the gravity dam 1 , thereby buffering the larger water pressure, and facilitate the replacement of the first baffle plate 8 , thereby extending the service life of the gravity dam 1 .
