Referring to fig. 1 and 2, the water inlet opening and closing machine structure comprises a supporting frame 3 installed along the edge of a water inlet 2 of a dam, and a gate 1 is arranged inside the supporting frame 3. The equal fixed mounting of inner wall of the both sides of carriage 3 has a gib block 4, and the guide way 5 that supplies gib block 4 to wear to establish is all seted up to the both sides of gate 1. The guide groove 5 moves in the guide strip 4, thereby improving the stability of the gate 1 when it is lifted.

Referring to fig. 1 and 2, an opening and closing chamber 6 is disposed at one side of the supporting frame 3, and the opening and closing chamber 6 is a space reserved when a dam is constructed, or a space newly excavated after the dam is constructed. A winch hoist 7 is fixedly arranged in the opening and closing chamber 6. The hoisting hoist 7 is provided with a lifting rope 8 in a matching way. The middle part of the top side of the supporting frame 3 is fixedly provided with a first fixed pulley 9, and the top side of the supporting frame 3 close to the edge of the opening and closing chamber 6 is fixedly provided with a second fixed pulley 10.

Referring to fig. 1 and 2, the top side of the gate 1 is provided with a clamping mechanism 12, and the clamping mechanism 12 includes a hanging ring 121, a first clamping plate 122, a second clamping plate 123, a top plate 124 and a first bolt 125. The top plate 124 abuts against the top side of the gate 1, and the first clamping plate 122 and the second clamping plate 123 are both fixedly installed on one surface of the top plate 124 close to the gate 1. The hanging ring 121 is fixedly installed on one surface of the top plate 124 far away from the gate 1. The first clamping plate 122 abuts against one surface of the gate 1, and the second clamping plate 123 abuts against the other surface of the gate 1. The first bolt 125 penetrates the first clamping plate 122, the second clamping plate 123 and the gate 1, so that the gate 1 is fixedly installed between the first clamping plate 122 and the second clamping plate 123. The hoist rope 8 is passed around from the side of the first fixed sheave 9 away from the gate 1 and the side of the second fixed sheave 10 away from the gate 1, after which the hoist rope 8 is attached to the suspension loop 121.

When the winch hoist 7 winds, the lifting rope 8 drives the gate 1 to ascend through the hanging ring 121; when the winch hoist 7 unreels, the gate 1 moves downward under the influence of gravity. The first fixed pulley 9 and the second fixed pulley 10 are used for changing the stress direction of the lifting rope 8 for pulling the gate 1, so that the gate 1 is vertically upwards pulled by the lifting rope 8, the power required by the winch hoist 7 for driving the gate 1 to ascend is reduced, and the effects of energy conservation and emission reduction are achieved.

The implementation principle of a water inlet headstock gear structure of this application embodiment does: the hoist 7 is installed inside the opening and closing chamber 6, thereby reducing a support structure that needs to be installed when installing the hoist 7. Meanwhile, the opening and closing chamber 6 is a space reserved during dam construction or a space dug on a dam, so that the cost for installing the winch hoist 7 is reduced.

Example 2.

Referring to fig. 3 and 4, the difference between the water inlet opening and closing mechanism structure in this embodiment and embodiment 1 is that a third fixed pulley 11 is fixedly installed on the inner wall of the opening and closing chamber 6 on the side close to the support frame 3. The lifting rope 8 is wound around the side of the third fixed pulley 11 close to the supporting frame 3. A first balancing weight 13 and a second balancing weight 14 are disposed between the third fixed pulley 11 and the second fixed pulley 10. The first counter weight block 13 is fixedly installed on the lifting rope 8. The second weight block 14 is located on a side of the first weight block 13 close to the third fixed pulley 11. At least one second balancing weight 14 is provided, and a second bolt 15 is arranged between the second balancing weight 14 and the first balancing weight 13 and between two adjacent second balancing weights 14. The second balancing weights 14 are connected with the first balancing weights 13, and two adjacent second balancing weights 14 are connected with each other through second bolts 15. The sum of the weights of the first and second counter-weight blocks 13 and 14 is less than the weight of the gate 1.

First balancing weight 13 and second balancing weight 14 are installed behind lifting rope 8, and first balancing weight 13 and second balancing weight 14 receive the influence of gravity to the downward pulling lifting rope 8 to make lifting rope 8 upwards pull gate 1. The first balancing weight 13 and the second balancing weight 14 assist the winch hoist 7 to pull the gate 1 to lift, so that the power required by the winch hoist 7 to pull the gate 1 to lift is reduced, and the effects of energy conservation and emission reduction are achieved.

The number of the second counter weight blocks 14 is increased or decreased, thereby facilitating the hoist 7 to be used for the gates 1 of different weights.

The second weight block 14 includes a first sub-block 141 and a second sub-block 142, and the first sub-block 141 and the second sub-block 142 are mutually abutted to form a through hole for the hanging rope 8 to pass through. After the second weight member 14 is removed from the first weight member 13, the second weight member 14 is divided into a first sub-block 141 and a second sub-block 142, thereby facilitating the removal of the second weight member 14 from the lifting rope 8.

Referring to fig. 3 and 5, two limiting sleeves 16 are further disposed between the second fixed pulley 10 and the third fixed pulley 11, and the first balancing weight 13 and the second balancing weight 14 are both located between the two limiting sleeves 16. The lifting rope 8 is arranged through the limiting sleeve 16, and the limiting sleeve 16 comprises a first sleeve 161 and a second sleeve 162. The second sleeve 162 is threaded through the first sleeve 161, and the first sleeve 161 is fixedly mounted on the inner wall of the opening/closing chamber 6 close to the supporting frame 3. The length of the second sleeve 162 passing through the first sleeve 161 is adjusted to change the height of the gate 1 after it is raised and lowered. The height of the gate 1 after ascending and descending can be changed, so that the opening size of the dam water inlet 2 can be conveniently controlled.

The implementation principle of a water inlet headstock gear structure of this application embodiment does: when the hoisting hoist 7 is wound, the first balancing weight 13 and the second balancing weight 14 assist the hoisting hoist 7 to pull the gate 1, so that the power required by the hoisting hoist 7 to pull the gate 1 to rise is reduced, and the energy-saving effect is achieved. When the winch hoist 7 unreels, the gate 1 descends, and the first balancing weight block 13 and the second balancing weight block 14 pull the gate 1 upwards through the lifting rope 8, so that the situation that the lifting rope 8 is broken at a high speed when the descending speed of the gate 1 is reduced occurs.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
