TECHNICAL FIELD
[0001] The application discloses a hydraulic gate capable of promoting gate closing, and applies to the field of water conservancy projects. BACKGROUND
[0002] The flat gate is often used as an emergency gate in water conservancy projects due to the simple structure, convenient and reliable operation, and easy cooperation with other buildings. In recent years, the gate cannot be completely closed due to insufficient closing force. The supporting pulley, sliding block and track of the flat gate are worn out due to long-term immersion in water, and the scale layer is attached to the gate, so that the friction coefficient of the gate is increased. When the gate is closed in the moving water, the closing force of the gate is less than the friction force when the friction coefficient is increased to a certain value, so that the gate cannot be further lowered, and finally the closing fails.
[0003] At present, the flat gate is mostly welded by multiple steel plates, the panel, beam plate and bottom edge are fixed, the water gravity and water thrust are constant values, and the actual situation cannot be adjusted. When the friction force is too large to cause the gate to be blocked, the gate cannot be quickly closed to cut off the water source. SUMMARY

[0006] Further, the main lifting lug is installed at the top of the gate, and is used for lifting the whole gate.
[0007] Further, the front water seal and the rear water seal both adopt P-type water seals.
[0008] Further, the lower surface of the upper beam of the bottom edge is provided with a buffer pad for supporting and buffering when the bottom edge is fully opened.
[0009] Further, the upper portion of the bottom edge is provided with a shaft ring corresponding to the pivot and the bearing, and the shaft ring penetrates the pivot, so that the bottom edge can rotate around the pivot.
[0010] Further, the upper beam is provided with a water permeable hole for water permeation, and for passing and guiding the door opening traction rope and / or the door closing traction rope.
[0011] Further, the bottom edge lifting lug, the door opening guide ring, the door opening traction rope and the water permeable hole on the upper surface of the bottom edge are approximately on the same plane, and the highest point of the bottom edge lifting lug on the upper surface of the bottom edge is lower than the lowest point of the door opening guide ring.
[0012] Further, the bottom edge lifting lug, the door closing guide ring, the door closing traction rope and the water permeable hole on the lower surface of the bottom edge are approximately on the same plane, and the lowest point of the bottom edge lifting lug on the lower surface of the bottom edge is higher than the lowest point of the door closing guide ring.
[0013] The above-mentioned water gate closing method of the water gate according to the present application can promote the closing of the water gate, and the initial state is that the water gate is in a high position, the door closing traction rope is taut, the bottom edge is closed, and the through hole is not over water; when the water gate cannot fall further due to insufficient closing force during the falling of the water gate in water, the door closing traction rope is loosened, the door opening traction rope is taut, the bottom edge rotates around the pivot, and the through hole is opened under the action of the door opening traction rope, so that part of the water flow flows to the downstream from the through hole, and another part of the water flow flows to the downstream from below the water gate, at this time, the water blocking area of the water gate is reduced, the water thrust is reduced, the friction is reduced, and the falling of the water gate is promoted.

DETAILED DESCRIPTION
[0021] The specific implementation of the present application will be further described below in combination with the drawings and examples.
[0022] A water gate capable of promoting the closing of the gate comprises a main lifting lug 1, a longitudinal beam 2, a cross beam 3, a panel 4, a buffer pad 5, a bottom edge 6, a bottom edge lifting lug 7, a front water seal 8, a through hole 9, a closing door traction rope 10, an opening door traction rope 11, a rotating shaft 12, a bearing 13, an opening door guide ring 14, a closing door guide ring 15, a water permeable hole 16 and a rear water seal 17. The gate is mainly composed of a plurality of cross beams 3 and longitudinal beams 2. The frame structure composed of the cross beams 3 and the longitudinal beams 2 is fixed on the panel 4 and mainly plays a supporting role. The rear water seal 17 is installed on the back of the panel 4 and plays a role of sealing water of the whole gate. The front of the gate is open and faces the upstream water. The panel 4 below the cross beam 3 at the lower end of the gate is provided with the through hole 9 for guiding the upstream water to the downstream through the through hole 9. The front water seal 8 is installed around the through hole 9 and is used for sealing water after the through hole 9 is closed. The rear water seal 17 and the front water seal 8 adopt P-shaped water seals and are used for water stopping. The front end of the through hole 9 at the lower side of the gate is provided with a rotatable bottom edge 6. The size of the bottom edge 6 is greater than that of the through hole 9, so that the bottom edge 6 can block the through hole 9 when the bottom edge 6 is closed. The bottom edge 6 can be controlled to open and close according to actual conditions and is used for changing the water passing area and the water gravity acting area of the through hole 9. As shown in the figure. Figures 1-4
[0023] The main lifting lug 1 is installed on the upper surface of the beam 3 at the top end of the gate, which is used for lifting the whole gate. The buffer pad 5 is installed on the lower surface of the beam 3 at the upper side of the bottom edge 6 at the lower end of the gate, which is used for supporting and buffering when the bottom edge 6 is fully opened. The opening door guide ring 14 is installed at the front end of the beam 3 of the gate, which is used for the opening door traction rope 11 to pass through the opening door guide ring 14 and guide the opening door traction rope 11 to open the bottom edge 6. The closing door guide ring 10 is installed on the panel 4, which is used to guide the closing door traction rope 10 to close the bottom edge 6. The water permeable hole 16 is arranged on the beam 3, which is used for water permeation and also used for passing and guiding the opening door traction rope 11 and / or the closing door traction rope 10. The rotating shaft 12 and the bearing 13 are arranged below the beam 3 at the lower end of the gate. The rotating shaft 12 is installed on the longitudinal beam 2 at the left and right sides of the gate and corresponds to the position above the bottom edge 6. The bearing 13 can be installed on the lower surface of the lower end beam 3 or on the panel 4. The bottom edge 6 is arranged below the lower end beam 3. The shaft ring is arranged on the upper part of the bottom edge 6 and corresponds to the position of the rotating shaft 12 and the bearing 13. The shaft ring passes through the rotating shaft 12, so that the bottom edge 6 can rotate around the rotating shaft 12 and be supported and fixed by the bearing. As shown in Figure 1 and Figure 4 .
[0024] The bottom edge lifting lug 7 is arranged on the upper and lower surfaces of the bottom edge 6, which is used for connecting the opening door traction rope 11 and the closing door traction rope 10. Specifically, the opening door traction rope 11 is connected to the bottom edge lifting lug on the upper surface of the bottom edge 6 through the opening door guide ring 14, which is used to open the bottom edge 6 to expose the through hole 9 for water passing. The closing door traction rope 10 is connected to the bottom edge lifting lug on the lower surface of the bottom edge 6 through the closing door guide ring 10, which is used to close the bottom edge 6 to close the through hole 9. More specifically, the opening door traction rope 11 is connected to the bottom edge lifting lug 7 on the upper surface of the bottom edge 6, passes through the opening door guide ring 14, is connected to the winch, and controls the opening of the bottom edge 6. The closing door traction rope 10 is connected to the bottom edge lifting lug 7 on the lower surface of the bottom edge 6, passes through the closing door guide ring 15 and the water permeable hole 16, is connected to the winch, and controls the closing of the bottom edge 6. When the opening door traction rope 11 is pulled by the winch, the opening door traction rope 11 pulls the bottom edge lifting lug 7 on the upper surface of the bottom edge 6 to open the bottom edge 6. After the bottom edge 6 is opened, the bottom edge 6 can be exposed outside the gate body. When the closing door traction rope 10 is pulled by the winch, the closing door traction rope 10 pulls the bottom edge lifting lug 7 on the lower surface of the bottom edge 6 to close the bottom edge 6. After the bottom edge 6 is closed, the bottom edge 6 covers the through hole 9 and closes the through hole 9. As shown in Figure 2 and Figure 3 .
[0025] The initial state is that the gate is in the high position, the closing door traction rope 10 is pulled tight, the bottom edge 6 is closed, and the through hole 9 is not over water. During the process of falling in water, when the closing door force is insufficient and the gate cannot fall further, the closing door traction rope 10 is loosened, the opening door traction rope 11 is pulled tight, the bottom edge 6 rotates around the rotating shaft 12, and the through hole 9 is opened under the action of the opening door traction rope 11, so that part of the water flow flows from the through hole 9 to the downstream, and the other part of the water flow flows from below the gate to the downstream. At this time, the water pushing force is reduced, the friction is reduced, the gate is closed, and the water weight area is changed from the area of the gate beam 3 to the downward projection area of the bottom edge 6. The downward projection area of the bottom edge 6 is larger than the area of the beam 3, so that the water weight is increased, and the gate is further closed.
[0026] When the gate is completely landed, the opening door traction rope 11 is loosened, the closing door traction rope 10 is pulled tight, the bottom edge 6 is closed under the action of the closing door traction rope 10, the through hole 9 is covered, the through hole 9 is not over water, and the closing door is ended.
[0027] When the closing door force is sufficient, the closing door traction rope 10 is always in a pulled state, and the bottom edge 6 and the through hole 9 are not opened, so that the gate can be closed in water.
[0028] When the gate runs for a long time and the friction increases obviously, the initial state can directly open the bottom edge 6 and the through hole 9, and then the gate is lowered in water to increase the closing door force and promote the gate to be closed.
[0029] During the closing process of the gate, the rotation angle of the bottom edge 6 can be adjusted to obtain appropriate friction and water weight, so that the gate can be completely closed, and the damage of the gate to the opening and closing facilities can be reduced.
[0030] It should be further pointed out that the above embodiments are only used to understand the technical solutions of the present application, and the up, down, front, back and other directions are only for convenient description and easy understanding, and multiple directions are not used to limit the specific number. For those skilled in the art, any structural description in the specific embodiments can be adjusted within the scope of those skilled in the art, and any obvious adjustment and modification made by them should also belong to the protection scope of the present application.
