Abstract

This utility model provides a bidirectional water-blocking flap gate structure, including a gate leaf, hinges, a gate slot embedded plate, and a hydraulic hoist. Bidirectional water seal structures are fixed on both sides of the gate leaf, located between the gate leaf and the gate slot embedded plate. A bottom water seal structure is provided on one side of the bottom of the gate leaf. The bidirectional water seal structure is fixed to the gate panel of the gate leaf via a pressure plate structure. The bottom water seal structure is fixed to the inner river side concrete base via a connecting plate structure. The end of the bottom water seal structure can be in close contact with the bidirectional water seal structure. By setting a bottom water seal structure and a bidirectional water seal structure that can cooperate with it on the gate leaf, the flap gate can achieve a bidirectional water-blocking effect within a certain rotation angle range, eliminating the need for a rubber water seal at the gate slot and reducing the installation accuracy requirements.

Description

Technical Field

[0001] This utility model relates to the field of sluice gate technology, and in particular to a bidirectional water-blocking flap gate structure. Background Technology

[0002] The common water-stopping structure of flap gates uses symmetrical convex arc-shaped rubber water seals between the gate leaf and the gate slot. The water-stopping effect is achieved by deforming the two convex arc-shaped water seals through compression. Since the water-stopping effect depends entirely on the elasticity of the rubber, high installation accuracy is required. Installation errors may lead to local leakage problems. In actual use, if the two convex arc-shaped water seals age, it may also lead to overall failure. Maintenance of the rubber water seals requires disassembling the gate leaf or gate slot, which is difficult. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bidirectional water-blocking flap gate structure, which can solve the problems of high installation accuracy requirements and difficult subsequent maintenance caused by the use of door groove rubber water seal for water-stopping in flap gates.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A bidirectional water-blocking flap gate structure includes a gate leaf, hinges, a gate slot embedded plate, and a hydraulic hoist. Bidirectional water seal structures are fixed to both sides of the gate leaf, located between the gate leaf and the gate slot embedded plate. A bottom water seal structure is provided on one side of the bottom of the gate leaf. The bidirectional water seal structure is fixed to the gate panel of the gate leaf via a pressure plate structure. The bottom water seal structure is fixed to the inner river side concrete base via a connecting plate structure. The end of the bottom water seal structure can be in close contact with the bidirectional water seal structure.

[0006] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0007] The bottom water seal structure includes two bottom water seals and two bottom water seal pressure plates. Both bottom water seals are round-headed P-type water seals. The two bottom water seals are fixed to the connecting plate structure by the two bottom water seal pressure plates and bottom water seal bolts.

[0008] The bidirectional water seal structure includes an inner river side water seal fixed to the inner river side of the gate panel, a first outer river side water seal and a second outer river side water seal fixed to the outer river side of the gate panel. The second outer river side water seal is connected to the tail end of the first outer river side water seal. The surface of the second outer river side water seal is flush with the inner river side surface of the gate panel. The end of the bottom water seal structure can be in close contact with the second outer river side water seal.

[0009] The tail end of the inner river side water seal is longer than the tail end of the first outer river side water seal by a length of d. The second outer river side water seal is connected to the first outer river side water seal end to end, and the overlapping part of the second outer river side water seal and the inner river side water seal has a length of d.

[0010] The inner river side water seal and the first outer river side water seal are both round-headed P-type water seals, and the second outer river side water seal is a square-headed P-type water seal. The square-headed protruding side of the second outer river side water seal is flush with the inner river side of the gate panel.

[0011] The pressure plate structure includes a first pressure plate located above the inner river side water seal, a second pressure plate located above the first outer river side water seal, and a third pressure plate located above the second outer river side water seal. A water seal pad is also provided in the gap between the second outer river side water seal and the gate panel. The inner river side water seal and the first outer river side water seal are fixed to the gate panel by the first pressure plate, the second pressure plate, and the first bolt structure. The overlapping part of the inner river side water seal and the second outer river side water seal is fixed to the gate panel by the first pressure plate, the third pressure plate, the water seal pad, and the second bolt structure. The part of the second outer river side water seal that does not overlap with the inner river side water seal is fixed to the gate panel by the third pressure plate, the water seal pad, and the flat-head bolt structure.

[0012] The water seal pad is welded to the gate panel. The outer weld of the water seal pad and the gate panel is a single-sided V-shaped weld with a smooth surface. The inner weld of the water seal pad and the gate panel is a fillet weld.

[0013] The surface of the flat-head bolt structure is coated with sealant.

[0014] The water seal pre-pressure width of the bottom water seal structure towards the gate leaf is e, and the value of e is greater than or equal to 6mm.

[0015] The pre-pressure width of the water seals on the inner river side, the first outer river side, and the second outer river side facing the gate slot embedded plate 5 is f, and the value of f is greater than or equal to 4mm.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: by setting a bottom water seal structure and setting a bidirectional water seal structure that can be used in conjunction with the bottom water seal structure on the gate leaf, the opening of the flap gate can achieve bidirectional water blocking effect within a certain rotation angle range, eliminating the need to set a rubber water seal at the gate slot and reducing the requirements for installation accuracy.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout. However, it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting this utility model. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0028] This utility model provides a bidirectional water-blocking flap gate structure, including a gate leaf 1, a hinge 2, a gate slot embedded plate 5, and a hydraulic hoist 6. Bidirectional water seal structures 4 are fixed on both sides of the gate leaf 1, and the bidirectional water seal structures 4 are located between the gate leaf 1 and the gate slot embedded plate 5. A bottom water seal structure 3 is provided on one side of the bottom of the gate leaf 1. The bidirectional water seal structure 4 is fixed to the gate panel 11 of the gate leaf 1 through a pressure plate structure. The bottom water seal structure 3 is fixed to the inner river side concrete base 9 through a connecting plate structure 8. The end of the bottom water seal structure 3 can be in close contact with the bidirectional water seal structure 4.

[0029] The connection of the gate leaf 1, the hinge 2, and the hydraulic hoist 6 are all common technical means, and will not be described in detail in this embodiment.

[0030] When the flip gate in this embodiment is working, the hydraulic hoist 6 drives the gate leaf 1 to rotate around the hinge 2. When the gate leaf 1 reaches the water blocking angle, the bottom water seal structure 2 and the bidirectional water seal structure 4 located on both sides of the gate leaf 1 have full contact, thereby ensuring that there is no water leakage at the bottom corners on both sides of the gate leaf 1.

[0031] The bottom water seal structure 3 includes two bottom water seals 31 and two bottom water seal pressure plates 32. Both bottom water seals 31 are round-headed P-type water seals. The two bottom water seals are fixed to the connecting plate structure 8 by the two bottom water seal pressure plates 32 and the bottom water seal bolt structure 33.

[0032] The bidirectional water seal structure 4 includes an inner river side water seal 41 fixed to the inner river side of the gate panel 11, a first outer river side water seal 42 fixed to the outer river side of the gate panel 11, and a second outer river side water seal 43. The second outer river side water seal 43 is connected to the tail end of the first outer river side water seal 42. The surface of the second outer river side water seal 43 is flush with the inner river side surface of the gate panel 11, and the end of the bottom water seal structure 3 can be in close contact with the second outer river side water seal 43.

[0033] The inner river side water seal 41 is used to prevent the water flow from the inner river side to the outer river side from leaking out. The first outer river side water seal 42 is used to prevent the water flow from the outer river side to the inner river side from leaking out. When the gate leaf 1 rotates around the hinge 2, the end of the bottom water seal structure 2 is always in contact with the second outer river side water seal 43.

[0034] The tail end of the inner river side water seal 41 is longer than the tail end of the first outer river side water seal 42 by a length of d. The second outer river side water seal 43 is connected to the first outer river side water seal 42 end to end, and the length of the overlapping part of the second outer river side water seal 43 and the inner river side water seal 41 is d.

[0035] The inner river side water seal 41 and the first outer river side water seal 42 are both round-headed P-type water seals, while the second outer river side water seal 43 is a square-headed P-type water seal. The square-headed protruding side of the second outer river side water seal 43 is flush with the inner river side of the gate panel 11.

[0036] The pressure plate structure includes a first pressure plate 71 located above the inner river side water seal 41, a second pressure plate 72 located above the first outer river side water seal 42, and a third pressure plate 73 located above the second outer river side water seal 43. A water seal pad 10 is also provided in the gap between the second outer river side water seal 43 and the gate panel 11. The inner river side water seal 41 and the first outer river side water seal 42 are fixed to the gate panel 11 by the first pressure plate 71, the second pressure plate 72 and the first bolt structure 44. The overlapping part of the inner river side water seal 41 and the second outer river side water seal 43 is fixed to the gate panel 11 by the first pressure plate 71, the third pressure plate 73, the water seal pad 10 and the second bolt structure 45. The part of the second outer river side water seal 43 that does not overlap with the inner river side water seal 41 is fixed to the gate panel 11 by the third pressure plate 73, the water seal pad 10 and the flat-head bolt structure 46.

[0037] The water seal pad 10 is welded to the gate panel 1. The outer weld 101 between the water seal pad 10 and the gate panel 1 adopts a single-sided V-shaped weld and the weld surface is smooth (it can be ground smooth after welding). The inner weld 102 between the water seal pad 10 and the gate panel 1 adopts a fillet weld.

[0038] The surface of the flat-head bolt structure 46 is coated with sealant 12 to ensure that the flat-head bolt structure 46 is tightly connected and there is no water leakage.

[0039] The water seal preload width of the bottom water seal structure 3 towards the gate leaf 1 is e, and the value of e is greater than or equal to 6mm.

[0040] The water seal preloading width of the inner river side water seal 41, the first outer river side water seal 42, and the second outer river side water seal 43 facing the gate slot buried plate 5 is f, and the value of f is greater than or equal to 4mm.

[0041] The pre-compression volume of the square-headed P-type water seal is larger than that of the round-headed P-type water seal. Therefore, the second outer river side water seal 43 can meet the bidirectional water blocking requirements. The second outer river side water seal 43 is shorter in length and is fixed by the bottom water seal structure 3 and the inner river side water seal 41 on both sides. Therefore, the second outer river side water seal 43 will not deform significantly towards the inner river side. At the same time, the third pressure plate 73 and the water seal pad 10 work together to support the second outer river side water seal 43, so that the second outer river side water seal 43 will not deform significantly towards the outer river side.
