Description

Technical Field

[0001] The present invention relates to a horizontal pressure device for gates arranged obliquely, and is applicable to the technical field of hydropower and water conservancy. Background Art

[0002] In hydropower and water conservancy projects, gates are crucial devices used to intercept water flow, control water levels, and regulate flow. For flat gates operating in inclined slots, their opening and closing processes are particularly critical. To reduce the opening and closing forces, a water filling valve is typically installed on the gate to fill the downstream side of the gate with water before opening to balance the water pressure.

[0003] Since the water filling valve needs to adapt to the inclination of the gate slot together with the gate, the water filling valve will generate an additional load in the direction perpendicular to the gate slot, and this load will increase with the increase of the inclination angle, thereby causing the guide shaft structure in the water filling valve to be stressed, the structural stiffness requirement of the water filling valve connecting plate to increase, and the water sealing requirement between the valve body and the water seal to increase. The existing water filling valve is difficult to meet the above requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in view of the above-mentioned problems, a gate filling level pressure device suitable for inclined arrangement is provided.

[0005] The technical solution adopted by the present invention is: a horizontal pressure device for gates with inclined arrangement, comprising:

[0006] a body chamber formed within the valve;

[0007] a valve water inlet, located on the gate plate on the upstream side of the gate and communicating with the valve body chamber;

[0008] A water diversion pipe is provided inside the gate, the water inlet at the upper end of the water diversion pipe is communicated with the valve body chamber and is fixedly connected to the gate via a horizontal web, and the water outlet at the lower end of the water diversion pipe passes through the gate plate on the downstream side of the gate;

[0009] A trolley box is arranged in the gate and located above the water inlet at the upper end of the water diversion pipe;

[0010] The valve body is arranged corresponding to the water inlet at the upper end of the water diversion pipe and can be used to block the water inlet at the upper end of the water diversion pipe. The upper end mounting plate of the valve body is arranged parallel to the gate plate. The upper end mounting plate is connected to the lower end of the connecting plate via a pin shaft. The upper end of the connecting plate is connected to the lower end of the pull rod box via a pin shaft.

[0011] The guide device is arranged corresponding to the water inlet at the upper end of the water diversion pipe, and has a guide channel therein that is adapted to the valve body and communicated with the water diversion pipe.

[0012] The water diversion pipe is composed of a vertical section, a transition section and an inclined section from top to bottom, wherein the inclined section gradually inclines toward the upstream side from top to bottom, and the vertical section smoothly transitions to the inclined section through the transition section.

[0013] The trolley case is equipped with a guide shaft arranged horizontally and parallel to the gate plate. The middle part of the guide shaft is installed on the trolley case, and the two ends of the guide shaft are installed on the ear plates on both sides of the trolley case. The ear plates are provided with guide holes on the plates corresponding to the guide shafts. The guide shaft is installed in the guide holes on the plates and can move up and down in the guide holes.

[0014] A second retaining ring is sleeved on the guide shaft. The second retaining ring is located between the lug plate and the trolley case, and the second retaining ring is fixedly connected to the trolley case.

[0015] The trolley case is provided with a second shaft parallel to the guide shaft, the two ends of the second shaft are respectively fixed to the ear plates on both sides of the trolley case, the middle part of the second shaft is installed in the guide hole on the trolley case, and the second shaft can move up and down in the guide hole on the case.

[0016] A retaining ring 1 is sleeved on the shaft 2, the retaining ring 1 is located between the lifting lug plate and the trolley case, and the retaining ring 1 is fixedly connected to the lifting lug plate.

[0017] The guide device comprises an upper guide ring and a lower guide ring, the upper guide ring and the lower guide ring are coaxially arranged and connected by a plurality of connecting steel plates.

[0018] The beneficial effects of the present invention are as follows: the upper mounting plate of the valve body of the present invention is arranged parallel to the gate plate (i.e., perpendicular to the water flow direction), the upper mounting plate is connected to the lower end of the connecting plate via a pin shaft, and the upper end of the connecting plate is connected to the lower end of the drawbar box via a pin shaft, thereby significantly increasing the area of the valve body in the key force direction, which not only improves the structural rigidity of the valve body, but also effectively disperses the stress generated by the water pressure, thereby reducing the impact of the additional load caused by the tilt on the performance of the water filling valve.

[0019] In this invention, the guide shaft is tightly secured to the luggage structure via a second retaining ring, ensuring stability and reliability between the guide shaft and the luggage. The end is secured to the lug plate via a stop ring or other means. The lug plate design allows for smooth movement of the guide shaft when necessary while also being able to withstand significant forces and moments.

[0020] Due to the inclined arrangement of the gate, the guiding accuracy of the water filling valve during opening and closing is particularly important. This invention adds a special guiding device to the water filling valve to limit the left and right swing of the valve body during opening and closing, ensuring that the valve body can accurately move up and down along the predetermined trajectory, improving the smoothness and reliability of operation.

[0021] In traditional filling valve designs, the layout of the outlet water pipe often ignores the potential impact of water flow on civil structures. The present invention divides the water pipe into a vertical section, a transition section, and an inclined section from top to bottom, with the inclined section arranged diagonally downward, that is, the water pipe extends from the outlet of the filling valve at a certain inclination angle, pointing downward. This layout optimizes the water flow path. After leaving the filling valve, the water flow no longer directly impacts the surrounding structures at a vertical angle, but flows out along the inclined direction of the water pipe, thereby reducing the direct impact of the water flow on the surrounding structures. At the same time, this layout also reduces the risk of structural damage caused by water flow impact and extends the service life of related facilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] This embodiment is a horizontal pressure device for gates with inclined arrangement, including a valve body chamber, a valve water inlet, a water diversion pipe, a drawbar box, a valve body, a guide device, etc.

[0033] In this example, the valve body chamber is formed inside the valve, and the valve water inlet is located on the gate plate on the upstream side of the gate. The valve water inlet is connected to the valve body chamber, and the water diversion pipe is arranged inside the gate, and its upper end water inlet is connected to the valve body chamber. The upper end of the water diversion pipe is fixedly connected to the gate through the horizontal web, and the water outlet at the lower end of the water diversion pipe passes through the gate plate on the downstream side of the gate.

[0034] In this embodiment, the water diversion pipe is composed of a vertical section, a transition section and an inclined section from top to bottom, wherein the inclined section gradually inclines toward the upstream side from top to bottom, and the vertical section smoothly transitions to the inclined section through the transition section.

[0035] In this embodiment, a closing mechanism capable of closing the water inlet is provided at the upper end of the water inlet corresponding to the water diversion pipe. The closing mechanism comprises a drawbar box, a valve body, a guide device, and the like.

[0036] In this example, the trolley box is arranged vertically inside the gate and is located above the water inlet at the upper end of the water diversion pipe; the valve body is arranged corresponding to the water inlet at the upper end of the water diversion pipe and can be used to block the water inlet at the upper end of the water diversion pipe. The upper mounting plate of the valve body is arranged parallel to the gate plate, and the upper mounting plate is connected to the lower end of the connecting plate via a pin shaft perpendicular to the upper mounting plate, and the upper end of the connecting plate is connected to the lower end of the trolley box via a pin shaft perpendicular to the upper mounting plate.

[0037] In this embodiment, the lower portion of the suitcase is equipped with a horizontal guide shaft arranged parallel to the gate plate. The middle portion of the guide shaft is mounted on the suitcase, and the ends of the guide shaft are mounted on the lifting lugs on either side of the suitcase. The lifting lugs are provided with guide holes corresponding to the guide shafts. The guide shafts are mounted in these guide holes and can move up and down within them. A second retaining ring is mounted on the guide shaft, positioned between the lifting lugs and the suitcase, and is fixedly connected to the suitcase.

[0038] Considering that during the opening and closing process of the inclined gate, the guide shaft will be subjected to a complex mechanical environment different from that of the conventional arrangement, especially a significant increase in lateral force. This embodiment has implemented a comprehensive reinforcement design for the guide shaft. By thickening the diameter of the guide shaft, thereby increasing the cross-sectional moment of inertia and shear area of the guide shaft, optimizing stress distribution, and improving material utilization, the bending and shear resistance of the guide shaft are significantly enhanced. At the same time, the use of high-performance alloy materials to manufacture the guide shaft further improves the overall load-bearing capacity and service life of the guide shaft.

[0039] In this example, a second shaft, parallel to the guide shaft, is mounted in the middle of the suitcase. Its ends are fixed to the lug plates on either side of the suitcase, and its center is inserted into a guide hole in the suitcase, allowing it to move up and down within the hole. A retaining ring is mounted on the second shaft, positioned between the lug plate and the suitcase, and fixedly connected to the lug plate.

[0040] In this embodiment, the guide device is fixed to the horizontal web and positioned corresponding to the water inlet at the upper end of the water diversion pipe. The guide device contains a guide channel that is compatible with the valve body and communicates with the water diversion pipe. The guide device comprises an upper guide ring and a lower guide ring. The upper and lower guide rings have the same inner diameter and are compatible with the valve body. The upper and lower guide rings are coaxially arranged and connected by a plurality of connecting steel plates arranged radially along the guide rings. A flow channel is formed between the connecting steel plates, and the distance between the inner ends of the connecting steel plates and the axis of the upper and lower guide rings is equal to the guide ring radius.

[0041] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
