[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-5As shown, the utility model provides a controllable flow type hydraulic gate, including a first dam body 1 and a second dam body 2, the first dam body 1 and the second dam body 2 are connected by a connecting frame 3, a gate opening assembly 4 and a filter assembly 5 are arranged between the first dam body 1 and the second dam body 2, and both are provided with a limiting groove 101, the gate opening assembly 4 also includes a screw 401 and a gate body 402, the screw 401 drives the gate body 402 to move vertically through two limiting grooves 101, the filter assembly 5 includes a filter baffle 501, a transmission assembly 6 is arranged between the gate body 402 and the filter baffle 501, the gate body 402 drives the filter baffle 501 to rotate when moving vertically through the transmission assembly 6, when the gate body 402 moves to the highest point, the filter baffle 501 can be rotated to a horizontal state, when the gate body 402 is at the lowest point, the filter baffle 501 rotates to a vertical state.

[0025] When the gate body 402 is operating normally, the gate body 402 can limit the amount of water discharged so that the discharged water will not excessively impact the filter baffle 501 when flowing. At this time, the filter baffle 501 is in a vertical state and can collect the garbage in the flow. The small water flow is also convenient for the staff to clean up the garbage. The safety factor is high and the cleanliness of the water flow can be improved, thereby improving the protection effect on nature and facilitating the use of subsequent water flow.

[0026] When a large amount of water needs to be discharged, the staff rotates the screw 401. After the screw 401 rotates, it can cooperate with the gate body 402 thread and drive the gate body 402 to move vertically upward under the limit of the first dam body 1 and the second dam body 2. When the gate body 402 moves, it can also drive the filter baffle 501 to move vertically upward. At the same time, under the action of the transmission component 6, the filter baffle 501 is driven to move and rotate at the same time. As the water flow gradually increases, the filter baffle 501 can gradually move to a higher position and rotate to a horizontal state. At this time, the filter baffle 501 no longer collects garbage, and reduces the contact area with the water flow, reduces the impact of the water flow on the filter baffle 501, thereby reducing the probability of damage to the filter baffle 501, extending the service life of the filter baffle 501, and improving applicability;

[0027] Gear meshing is common knowledge and will not be explained here.

[0028] In one embodiment, the gate opening assembly 4 also includes a motor 403, a rotating shaft 404, a driving gear 405 and a multi-tooth gear 407. The rotating shaft 404 is fixedly connected to the output end of the motor 403, and one end is fixedly connected to the driving gear 405. The multi-tooth gear 407 is fixedly installed on one end of the screw 401 and meshes with the driving gear 405. The two ends of the gate body 402 are slidably matched with the limit groove 101. The gate body 402 is sleeved on the screw 401 and is threadedly connected to the screw 401.

[0029] When a large amount of water needs to be discharged, the staff starts the motor 403. When the output end of the motor 403 rotates, it first drives the rotating shaft 404 to rotate. After the rotating shaft 404 rotates, it drives the driving gear 405 to rotate. Since the driving gear 405 is meshed with the multi-tooth gear 407 and has less teeth than the multi-tooth gear 407, after the driving gear 405 rotates, it can drive the screw 401 to slow down relative to the rotating shaft 404 through the multi-tooth gear 407. After the screw 401 rotates, it can cooperate with the gate body 402 thread, and under the limit of the first dam body 1 and the second dam body 2, it can drive the gate body 402 to move vertically upward, thereby adjusting the discharge volume of the water flow.

[0030] In one embodiment, the filter assembly 5 further includes a fixing rod 502 , and the filter baffle 501 is fixedly sleeved on the fixing rod 502 .

[0031] When the gate body 402 moves, the gate body 402 drives the fixed rod 502 to move through the transmission assembly 6. Since the filter baffle 501 is sleeved on the fixed rod 502, the fixed rod 502 can drive the filter baffle 501 to move, so that the filter baffle 501 and the gate body 402 are linked to improve the coordination between the equipment and applicability.

[0032] In one embodiment, the transmission assembly 6 includes a connecting rod 601, a transmission gear 602 and a rack 603. The two connecting rods 601 are fixedly connected to the gate body 402 and are both mounted on the fixed rod 502. The transmission gear 602 is fixedly installed at one end of the fixed rod 502. The rack 603 is fixedly connected to one end of the first dam body 1 and meshes with the transmission gear 602.

[0033] When the gate body 402 moves, the two connecting rods 601 drive the fixed rod 502 and the filter baffle 501 to move vertically upward. At the same time, the fixed rod 502 drives the transmission gear 602 to move. When the transmission gear 602 moves, it engages with the rack 603 and drives the fixed rod 502 and the filter baffle 501 to rotate, so that when the gate body 402 moves vertically upward, the filter baffle 501 can move and rotate at the same time, so that the filter baffle 501 can reasonably adjust its functionality according to the size of the water flow, thereby improving applicability.

[0034] In one embodiment, the transmission assembly 6 further includes a sliding groove 604 , and two connecting rods 601 respectively penetrate the first dam body 1 and the second dam body 2 and are connected to the limiting groove 101 . The connecting rod 601 is disposed in the sliding groove 604 .

[0035] The sliding groove 604 is used for the movement of the connecting rod 601, providing a moving space to prevent parts from colliding and being damaged.

[0036] In one embodiment, the gate opening assembly 4 further includes a mounting plate 406 , which is fixedly mounted on the top of the first dam body 1 and the second dam body 2 , and the mounting end of the motor 403 is fixedly connected to the top of the mounting plate 406 .

[0037] The mounting plate 406 is used to fix the motor 403 and other parts to improve the fixing effect of the equipment.

[0038] In one embodiment, a protective shell 7 is fixedly mounted on one end of the first dam body 1 and the second dam body 2 , and the connecting rod 601 , the transmission gear 602 and the rack 603 are respectively arranged in the two protective shells 7 .

[0039] The protective shell 7 can protect the transmission assembly 6, prevent the transmission assembly 6 from being damaged by garbage, and extend the service life of the transmission assembly 6.

[0040] The working principle of the controllable flow type hydraulic gate is described in detail below.

[0041] When the gate body 402 is operating normally, the gate body 402 can limit the amount of water discharged so that the discharged water will not excessively impact the filter baffle 501 when flowing. At this time, the filter baffle 501 is in a vertical state and can collect the garbage in the flow. The small water flow is also convenient for the staff to clean up the garbage. The safety factor is high and the cleanliness of the water flow can be improved, thereby improving the protection effect on nature and facilitating the use of subsequent water flow.

[0042] When a large amount of water needs to be discharged, the staff starts the motor 403. When the output end of the motor 403 rotates, it first drives the rotating shaft 404 to rotate. After the rotating shaft 404 rotates, it drives the driving gear 405 to rotate. Since the driving gear 405 is meshed with the multi-tooth gear 407 and has less teeth than the multi-tooth gear 407, after the driving gear 405 rotates, it can drive the screw 401 to rotate at a reduced speed relative to the rotating shaft 404 through the multi-tooth gear 407. After the screw 401 rotates, it can cooperate with the gate body 402 thread and drive the gate body 402 to move vertically upward under the limit of the first dam body 1 and the second dam body 2. When the gate body 402 moves, it drives the fixing rod 502 and the filter baffle 502 through the two connecting rods 601. The plate 501 moves vertically upward, and at the same time, the fixed rod 502 drives the transmission gear 602 to move. When the transmission gear 602 moves, it meshes with the rack 603 and drives the fixed rod 502 and the filter baffle 501 to rotate, so that when the gate body 402 moves vertically upward, the filter baffle 501 can move and rotate at the same time. As the water flow gradually increases, the filter baffle 501 can gradually move to a higher position and rotate to a horizontal state. At this time, the filter baffle 501 no longer collects garbage, and reduces the contact area with the water flow, reduces the impact of the water flow on the filter baffle 501, thereby reducing the probability of damage to the filter baffle 501, extending the service life of the filter baffle 501, and improving applicability;

[0043] When the water flow is reduced again, the gate body 402 moves vertically downward, and the transmission assembly 6 drives the filter baffle 501 to move to the initial position again and rotate to a vertical state, so that the filter baffle 501 can reasonably adjust its functionality according to the size of the water flow, thereby improving applicability again.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
