Description

Technical Field

[0001] The utility model relates to the field of water conservancy and hydropower engineering, in particular to a super-large span sluice. Background Art

[0002] With the continuous improvement of environmental and ecological requirements, many sluice gates are set up at river mouths and river estuaries. While meeting the needs of upstream water storage, they need to be submerged in the water from time to time to meet the needs of fish migration, etc. This type of sluice gate usually has the characteristics of large opening span, but low water retaining height and operating head. When the opening span of the sluice gate exceeds a certain size, the traditional left and right supporting structure gate will be very large, and the traditional hoist arrangement type with left and right hanging points will also cause huge pressure on the design of civil engineering structure due to its huge capacity. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a super-large span sluice gate, which adopts a new arrangement and structural type of gate and hoist so that it is not restricted by the span of the sluice gate, thereby expanding its scope of application.

[0004] The purpose of the utility model is achieved through the following technical solutions: This super-large span water gate includes:

[0005] A gate house is arranged along the span direction of the sluice gate, and the gate house is always located underwater, with an opening formed above the gate house;

[0006] The supporting gate slot is arranged on the upstream side wall, downstream side wall and gate pier at the bottom of the gate library;

[0007] The door leaf comprises a lower structure slidably supported on the supporting door slot and an upper structure fixed on the lower structure, wherein the door leaf moves up and down along the supporting door slot longitudinally in the door garage; and

[0008] The hoist includes a cylinder fixed to the bottom of the door, and the cylinder drives the upper structure through a piston rod;

[0009] When the piston rod extends outward, the upper structure lifts up to close the orifice to block water, and when the piston rod retracts, the upper structure retracts into the door storage to open the orifice.

[0010] As a further technical solution, the hydraulic pump station of the gate hoist is arranged in the corridor inside the downstream side wall, and the hydraulic pump station is connected to the oil cylinder through a hydraulic pipeline.

[0011] As a further technical solution, the upper structure serves as a water retaining structure, the lower structure serves as a supporting structure, and the load borne by the upper structure is transmitted to the supporting door groove through the lower structure.

[0012] As a further technical solution, the upstream and downstream sides of the support structure are provided with laterally discontinuously arranged support slideways, wherein upstream guides and upstream supports are provided on the support gate grooves corresponding to the upstream side walls, and downstream guides and downstream supports are provided on the support gate grooves corresponding to the downstream side walls.

[0013] As a further technical solution, the lower structure of the door leaf adopts a pontoon structure.

[0014] As a further technical solution, a high-level sand flushing hole is opened on the side wall of the supporting gate slot close to the downstream side wall, and a low-level sand flushing hole is opened at the bottom of the supporting gate slot close to the upstream side wall. Valves are provided at the entrances of the high-level sand flushing hole and the low-level sand flushing hole.

[0015] As a further technical solution, multiple cylinders of the gate hoist are arranged along the span direction, and the number of cylinders is adjusted according to the structural size and the opening and closing capacity of the sluice.

[0016] The beneficial effects of the utility model are:

[0017] 1. The gate adopts a longitudinal structure, and the lower part is supported in the gate house. Due to the low water retaining height, the gate structure is relatively light and will not cause great pressure on the design of the civil structure;

[0018] 2. The door leaf structure size and the opening and closing capacity and lift of the hoist are only related to the water retaining height of the gate and have nothing to do with the orifice width; it is particularly suitable for water gates with large orifice spans.

DETAILED DESCRIPTION

[0022] The utility model will be described in detail below with reference to the accompanying drawings:

[0023] Example: As shown in the attached Figure 1 , 2As shown, this super-large span water gate includes a gate house 1, a supporting gate slot 2, an upstream side wall 3, a downstream side wall 4, a gate pier 5, an upper structure 6, a lower structure 7, an oil cylinder 8, a hydraulic pump station 9, an orifice 10, a piston rod 11, an upstream guide 12, an upstream support 13, a downstream guide 14, a downstream support 15, a hydraulic pipeline 16, a high-level sand flushing hole 17, a low-level sand flushing hole 18, a valve 19 and a hoist.

[0024] Reference Figure 1 , 2 The sluice gate is provided with a gatehouse 1 which is connected along the span direction and has a certain depth. When the gate (gate leaf) is opened, it sinks into the gatehouse 1. When it is necessary to close the water barrier, the hydraulic hoist is used to push the gatehouse 1 out. The gatehouse 1 is always located underwater, and an orifice 10 is opened above the gatehouse 1.

[0025] The supporting gate slot 2 is arranged on the upstream side wall 3, downstream side wall 4 and gate pier 5 at the bottom of gate 1 (downstream side of gate leaf) of gate 1. The gate leaf is composed of upper and lower parts, and the lower structure 7 is a supporting structure, which is always located in the supporting gate slot 2 of gate 1 and can be made into a pontoon structure as required. The upper structure 6 is a water retaining structure, which is fixed on the lower structure 7. The load borne by the upper structure 6 is transmitted to the supporting gate slot 2 through the lower structure 7. The lower structure 7 is slidably supported on the supporting gate slot 2, so that the gate leaf moves up and down along the supporting gate slot 2 in the gate 1. Preferably, a transversely intermittently arranged supporting slideway is provided on the upstream and downstream sides of the supporting structure, wherein an upstream guide 12 and an upstream support 13 are provided on the supporting gate slot 2 corresponding to the upstream side wall 3, and a downstream guide 14 and a downstream support 15 are provided on the supporting gate slot 2 corresponding to the downstream side wall 4. In addition, on the downstream side of the gate leaf, a water seal device is provided above the supporting slideway, and a water seal plate is provided on the civil structure corresponding to the water seal device.

[0026] Furthermore, the gate hoist adopts a hydraulic gate hoist, which includes a cylinder 8 fixed at the bottom of the gate 1. A plurality of cylinders 8 are arranged along the span direction, and the number of cylinders 8 is adjusted according to the structural size and the opening and closing capacity of the sluice. The cylinder 8 is connected to drive the upper structure 6 through the piston rod 11. When the piston rod 11 is extended, the upper structure 6 lifts up and closes the orifice 10 to block water. When the piston rod 11 is retracted, the upper structure 6 is retracted into the gate 1 to open the orifice 10. Preferably, the hydraulic pump station 9 of the gate hoist is arranged in the corridor in the downstream side wall 4, and the hydraulic pump station 9 is connected to the cylinder 8 through the hydraulic pipeline 16.

[0027] As a preferred technical solution, a high-level sand flushing hole 17 is opened on the side wall of the supporting gate slot 2 near the downstream side wall 4, and a low-level sand flushing hole 18 is opened at the bottom of the supporting gate slot 2 near the upstream side wall 3, and valves 19 are provided at the entrances of the high-level sand flushing hole 17 and the low-level sand flushing hole 18.

[0028] The working process of the utility model is as follows: the sluice gate is provided with a gatehouse which is connected along the span direction and has a certain depth. When the gate is opened, it sinks into the gatehouse. When the water retaining device needs to be closed, a hydraulic hoist is used to push out the gatehouse. The gate adopts a longitudinal structure, and the lower part is supported in the gatehouse. Due to the low water retaining height, the gate structure is relatively light. One end of the hydraulic hoist is fixed to the bottom of the gatehouse, and the other end is connected to the gate leaf. When the gate is opened, the oil cylinder retracts into the gate leaf structure. The number of hoist oil cylinders can be combined with the gate structure size and the opening and closing capacity. After comprehensive consideration, multiple arrangements can be made along the span direction. Since the gate and the opening and closing equipment of the utility model adopt a longitudinal structure, the gate leaf structure size and the opening and closing capacity and lift of the hoist are only related to the water retaining height of the gate, and have nothing to do with the orifice width. Therefore, it is particularly suitable for sluice gates with large orifice spans.

[0029] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
