Description

Technical Field

[0001] This utility model discloses a hydraulic gate that can cause the gate to close, which is applied in the field of water conservancy engineering. Background Technology

[0002] Planar gates, due to their simple structure, convenient and reliable operation, and ease of integration with other structures, are often used as emergency gates in hydraulic engineering. In recent years, however, there have been frequent occurrences of gates failing to close completely due to insufficient closing force. When planar gates are submerged in water for extended periods, the supporting pulleys, sliders, and tracks wear down, and scale builds up, increasing the gate's coefficient of friction. When the gate closes in flowing water, if the coefficient of friction increases to a certain value, the closing force becomes less than the friction force, preventing the gate from descending further and ultimately causing closure failure.

[0003] Currently, most planar gates are welded from multiple steel plates. The structure, such as the panel, beam, and bottom edge, is fixed. The water gravity and water thrust are constant and cannot be adjusted according to the actual situation. When the friction is too great and causes the gate to jam, it cannot be quickly closed to cut off the water source. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model discloses a hydraulic gate that can cause the gate to close. The gate panel has holes, and the bottom edge is used to adjust the water-blocking area of ​​the gate, thereby changing the water thrust and friction. At the same time, the bottom edge is used to adjust the area of ​​the water weight, thereby changing the water gravity, and ultimately causing the gate to close.

[0005] The technical solution adopted in this utility model is: A hydraulic gate that can cause the gate to close includes a main lifting lug, longitudinal beams, transverse beams, a panel, a buffer pad, a bottom edge, bottom edge lifting lugs, a front water seal, a through hole, a closing traction rope, an opening traction rope, a rotating shaft, a bearing, an opening guide ring, a closing guide ring, a water permeable hole, and a rear water seal. A frame structure composed of several transverse and longitudinal beams is fixed to the panel. A rear water seal is installed on the back of the panel. The front of the gate is open, facing upstream water. A through hole is provided at the bottom of the panel, and a front water seal is installed around the through hole. A water seal is provided at the front end of the through hole. The bottom edge is rotatable and its size is larger than the through hole, so that the bottom edge can block the through hole when closed. Both the upper and lower surfaces of the bottom edge are provided with bottom edge lifting lugs, which are used to connect the opening traction rope and the closing traction rope. An opening guide ring is installed at the front end of the gate beam, and a closing guide ring is installed on the panel. The opening traction rope is connected to the bottom edge lifting lug on the upper surface of the bottom edge through the opening guide ring, which is used to open the bottom edge. The closing traction rope is connected to the bottom edge lifting lug on the lower surface of the bottom edge through the closing guide ring, which is used to close the bottom edge.

[0006] Furthermore, the main lifting lug is installed on the top of the gate for the overall lifting and lowering of the gate.

[0007] Furthermore, both the front and rear water seals use P-type water seals.

[0008] Furthermore, a buffer pad is installed on the lower surface of the crossbeam on the upper side of the bottom edge for support and cushioning when the bottom edge is fully open.

[0009] Furthermore, shafts and bearings are installed on the longitudinal beams on the left and right sides of the gate at positions corresponding to the top of the bottom edge. A collar is installed on the upper part of the bottom edge at a position corresponding to the shaft and bearing. The collar passes through the shaft, allowing the bottom edge to rotate around the shaft.

[0010] Furthermore, permeable holes are provided on the crossbeam for water to pass through, and also for passing through and guiding the door opening traction rope and / or door closing traction rope.

[0011] Furthermore, the bottom edge lifting lug, door opening guide ring, door opening traction rope, and 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] Furthermore, the bottom edge lifting lug, door closing guide ring, door closing traction rope, and 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 hydraulic gate closing method described above, which enables the gate to close, provided by this utility model, initially has the gate in a high position, with the closing traction rope taut, the bottom edge closed, and no water passing through the through hole. During the process of the gate falling in the water, when the gate closing force is insufficient and the gate cannot fall further, the closing traction rope is loosened, the opening traction rope is tightened, and the bottom edge rotates around the pivot. Under the pulling force of the opening traction rope, the through hole is opened, allowing part of the water to flow downstream through the through hole and another part of the water to flow downstream from below the gate. At this time, the water-blocking area of ​​the gate decreases, the water thrust decreases, and the friction decreases, causing the gate to fall and close. Once the gate has fully landed, loosen the opening traction rope and tighten the closing traction rope. The bottom edge closes under the tension of the closing traction rope, covering the through hole. Water will not pass through the through hole, and the gate closure is complete.

[0014] Furthermore, in this invention, when the gate closing force is sufficient, the closing traction rope is always taut, allowing the gate to fall and close underwater without opening the bottom edge and through hole. When the friction of the gate increases significantly, the bottom edge and through hole are opened directly in the initial state, and then the gate is lowered in the water to increase the closing force and cause the gate to close.

[0015] The beneficial effects of this utility model are: (1) Making holes in the panel to allow water to pass through can reduce the area of ​​water thrust and reduce friction, which is beneficial for the gate to close.

[0016] (2) After the bottom edge extends, the area of ​​action of water gravity increases, which is conducive to the closure of the gate.

[0017] (3) This utility model can be applied to hydraulic gates that are submerged in water for a long time, and the gate can be closed even if the friction increases.

[0018] (4) The friction and gravity of the gate can be adjusted according to the actual situation, and there is no need for frequent maintenance of the gate. Attached Figure Description

[0021] The specific implementation of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] A hydraulic gate that can cause the gate to close includes a main lifting lug 1, longitudinal beams 2, transverse beams 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 traction rope 10, an opening traction rope 11, a rotating shaft 12, a bearing 13, an opening guide ring 14, a closing guide ring 15, a water permeable hole 16, and a rear water seal 17. The gate is mainly composed of several transverse beams 3 and longitudinal beams 2. The frame structure formed by the transverse beams 3 and longitudinal beams 2 is fixed to the panel 4, mainly serving a supporting function. A rear water seal 17 is installed on the back of the panel 4, which serves to seal the water of the entire gate. The front of the gate is open, facing the upstream water. A through hole 9 is provided on the panel 4 below the transverse beams 3 at the lower end of the gate, for diverting upstream water to the downstream through the through hole 9. A front water seal 8 is installed around the through hole 9 for sealing the water after the through hole 9 is closed. The rear water seal 17 and the front water seal 8 adopt a P-type water seal for water stoppage. The lower side of the gate has a rotatable bottom edge 6 at the front end of the through hole 9. The bottom edge 6 is larger than the through hole 9, so that it can seal the through hole 9 when closed. The bottom edge 6 can be controlled to open and close according to actual conditions, thereby changing the water flow area and the area affected by water weight in the through hole 9. Figures 1-4 As shown.

[0023] A main lifting lug 1 is installed on the upper surface of the crossbeam 3 at the top of the gate for overall gate lifting and lowering. A buffer pad 5 is installed on the lower surface of the crossbeam 3 on the upper side of the bottom edge 6 of the gate for support and buffering when the bottom edge 6 is fully open. An opening guide ring 14 is installed at the front end of the crossbeam 3 of the gate for the opening traction rope 11 to pass through the opening guide ring 14 and guide the opening traction rope 11 to open the bottom edge 6. A closing guide ring 10 is installed on the panel 4 for guiding the closing traction rope 10 to close the bottom edge 6. A water permeable hole 16 is provided on the crossbeam 3 for water permeation and for passing through and guiding the opening traction rope 11 and / or the closing traction rope 10. A rotating shaft 12 and a bearing 13 are arranged below the crossbeam 3 at the lower end of the gate. The rotating shaft 12 is installed on the longitudinal beams 2 on the left and right sides of the gate at positions corresponding to the upper part of the bottom edge 6. The bearing 13 can be installed on the lower surface of the lower crossbeam 3 or on the panel 4. The bottom edge 6 is located below the lower crossbeam 3. A collar is installed on the upper part of the bottom edge 6 at a position corresponding to the rotating shaft 12 and the bearing 13. The collar passes through the rotating shaft 12, allowing the bottom edge 6 to rotate around the rotating shaft 12. The bearing provides support and fixation. Figure 1 and Figure 4 As shown.

[0024] Bottom edge 6 has bottom edge lifting lugs 7 on both its upper and lower surfaces. These lugs connect the opening traction rope 11 and the closing traction rope 10. Specifically, the opening traction rope 11 connects to the bottom edge lifting lug on the upper surface of bottom edge 6 via an opening guide ring 14, opening bottom edge 6 to expose a through hole 9 through which water flows. The closing traction rope 10 connects to the bottom edge lifting lug on the lower surface of bottom edge 6 via a closing guide ring 10, closing bottom edge 6 and shutting off through hole 9. More specifically, the opening traction rope 11 connects to the bottom edge lifting lug 7 on the upper surface of bottom edge 6, passes through the opening guide ring 14, connects to a winch, and controls the opening of bottom edge 6. The closing traction rope 10 connects to the bottom edge lifting lug 7 on the lower surface of bottom edge 6, passes through a closing guide ring 15 and a water-permeable hole 16, connects to a winch, and controls the closing of bottom edge 6. When the opening traction rope 11 is pulled by a winch, the opening 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, it can protrude outside the gate body. When the closing traction rope 10 is pulled by a winch, the closing 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, it covers the through hole 9 and closes the through hole 9. Figure 2 and Figure 3 As shown.

[0025] Initially, the gate is in a high position, the closing traction rope 10 is taut, the bottom edge 6 is closed, and the through hole 9 does not allow water to pass through. During the gate's descent in the water, when the gate's closing force is insufficient and the gate cannot descend further, the closing traction rope 10 is loosened, and the opening traction rope 11 is tightened. The bottom edge 6 rotates around the pivot 12, and under the action of the opening traction rope 11, the through hole 9 is opened, allowing some water to flow downstream through the through hole 9, and another part of the water to flow downstream from below the gate. At this time, the gate's water-blocking area decreases, the water thrust decreases, and the friction decreases, causing the gate to fall and close. At the same time, after the bottom edge 6 opens, the area of ​​water weight action changes 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 greater than the area of ​​the beam 3, increasing the water's weight and further causing the gate to close.

[0026] Once the gate has fully landed, loosen the opening traction rope 11 and tighten the closing traction rope 10. The bottom edge 6 closes under the tension of the closing traction rope 10, covering the through hole 9. Water does not pass through the through hole 9, and the gate closure ends.

[0027] When the gate closing force is sufficient, the closing traction rope 10 is always taut, and the gate can be lowered and closed underwater without opening the bottom edge 6 and the through hole 9.

[0028] When the gate has been running for a long time and the friction has increased significantly, the bottom edge 6 and the through hole 9 can be opened directly in the initial state, and then the gate can be lowered into the water to increase the closing force and cause the gate to close.

[0029] During the gate closing process, the rotation angle of the bottom edge 6 can be adjusted to obtain appropriate friction and water gravity, which can promote the complete closure of the gate and reduce the damage of the gate to the opening and closing facilities.

The terms "up," "down," "front," and "rear" are only for ease of description and understanding, and "multiple" are not intended to limit the specific quantity. For those skilled in the art, any structural description in the specific embodiments can be adjusted within the scope of their understanding, and any obvious adjustments and modifications made thereto should also fall within the protection scope of this utility model.
