[0005] In order to facilitate flow regulation by a sluice, the present application provides a sluice for a hydraulic project that facilitates flow regulation.

[0006] The present application provides a water gate for a hydraulic project that is convenient for flow regulation, which adopts the following technical solution:

[0007] A sluice gate for a water conservancy project that facilitates flow regulation comprises a sluice gate body, the sluice gate body being provided with a gate and a lifting rod, the lifting rod being threadedly connected to the sluice gate body, the lifting rod being connected to the gate, the gate sliding on the sluice gate body, the sliding direction of the gate being vertical, the gate being provided with a first drainage hole, the sluice gate body being provided with a diversion gate, the diversion gate being provided with a second drainage hole, the second drainage hole being used to communicate with the first drainage hole; the diversion gate being provided with a guide groove, the extension direction of the guide groove being vertical, the gate being provided with a guide block, the guide block being embedded in the guide groove, and when the first drainage hole is connected to the second drainage hole, the guide block abuts against the inner wall of the guide groove close to the lifting rod.

[0008] By adopting the above technical solution, a gate and a drainage gate are set. When discharge is required, the gate is moved by rotating the lifting rod. The gate moves so that the drainage hole 1 is connected with the drainage hole 2. At this time, the gate plays a role of discharge. When the discharge rate needs to be increased, the gate is continued to be moved so that the guide block abuts against the inner wall of the guide groove close to the lifting rod. At this time, the drainage hole 1 is completely connected with the drainage hole 2, and the movement of the gate drives the movement of the drainage gate. In actual use, the water flow has a large impact when it flows out from the lower part of the gate. Therefore, the above-mentioned discharge method reduces the damage to the lower part of the gate. Secondly, it is convenient for the gate to discharge quickly.

[0009] Optionally, the sluice body is provided with a base, the base is located on a side of the gate away from the lifting rod, and the base is provided with a shielding portion, the shielding portion is located on a side of the gate away from the diversion gate.

[0010] By adopting the above technical solution, a base is provided, and the base is used to shield the side of the gate close to the base, thereby reducing the impact on the gate. Secondly, it reduces the area where gravel is stuck between the base and the gate, which facilitates the closing of the gate.

[0011] Optionally, the shielding portion is provided with a guiding surface, the guiding surface is located on a side of the shielding portion away from the gate, and the guiding surface extends from a direction away from the base toward a direction close to the gate.

[0012] By adopting the above technical solution, a guide surface is provided to guide the movement of gravel, so that the gravel can pass through drainage hole one and drainage hole two, thereby reducing the accumulation of gravel at the base and improving the safety of subsequent gate opening and discharge.

[0013] Optionally, the base is provided with a mounting groove, a groove wall of the mounting groove is provided with a limit spring, the limit spring is connected to the shielding part, and the shielding part abuts against the gate.

[0014] By adopting the above technical solution, a limit spring is set. When the gate moves and drives the drainage gate to move, the limit spring causes the baffle to move and block the position where the gate hits the base. In this way, the situation where gravel remains on the base and affects the resetting of the gate is reduced, which facilitates the opening and closing of the gate.

[0015] Optionally, the shielding part is provided with a limiting slope, the limiting slope is located at the end of the shielding part away from the guide surface, the limiting slope is provided with a limiting groove, and the extending direction of the limiting groove is the inclination direction of the limiting slope; the gate is provided with a limiting part, the limiting part is provided with a limiting block, and the limiting block is embedded in the limiting groove; when the gate contacts the base, the limiting spring is in a normal state; when the gate moves in a direction away from the base, the shielding part moves in a direction close to the drainage gate, and the limiting spring is in a compressed state.

[0016] By adopting the above technical solution, a limit groove and a limit block are set. When the gate contacts the base, the limit spring is in a normal state. When the gate moves away from the base, the limit block moves together and drives the shielding part to move. At this time, the limit spring is in a compressed state, thereby facilitating the subsequent resetting of the shielding part.

[0017] Optionally, the diversion gate is provided with an inclined surface, the inclined surface is located at one end of the diversion gate close to the base, and the inclined surface extends in a direction away from the base toward a direction away from the gate.

[0018] By adopting the above technical solution, an inclined surface is set, which is used to press the gravel located at the contact point between the drainage gate and the base and drive it to the side of the drainage gate away from the gate. In actual use, the gate and the shielding part play a major role in limiting flow and bearing pressure, so setting the inclined surface has little effect on the overall pressure.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. Set up the gate and the drainage gate. When it is necessary to release the water, the gate is moved by rotating the lifting rod. The gate moves so that the drainage hole 1 is connected with the drainage hole 2. At this time, the gate plays a role in releasing the water. When it is necessary to increase the discharge rate, the gate is continued to be moved so that the guide block contacts the inner wall of the guide groove close to the lifting rod. At this time, the drainage hole 1 is completely connected with the drainage hole 2. The movement of the gate drives the movement of the drainage gate. In actual use, the water flow has a large impact when it flows out from the lower part of the gate. Therefore, the above-mentioned discharge method reduces the damage to the lower part of the gate. Secondly, it is convenient for the gate to release the water quickly.

[0021] 2. A guide surface is provided to guide the movement of the gravel, so that the gravel can pass through the drainage hole 1 and the drainage hole 2, thereby reducing the accumulation of gravel at the base and improving the safety of subsequent gate opening and discharge;

[0022] 3. Set the limit groove and limit block. When the gate contacts the base, the limit spring is in normal state. When the gate moves away from the base, the limit block moves together and drives the shielding part to move. At this time, the limit spring is in a compressed state, which facilitates the subsequent resetting of the shielding part. BRIEF DESCRIPTION OF THE DRAWINGS
