Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sliding connection device for adaptively adjusting the underwater form of a flexible main structure. Background Art

[0002] In the technical field of water conservancy projects, flexible main structures are increasingly widely used, mainly including rubber dams, anti-pollution curtains, floating barriers, flexible curtains, and water isolation curtains. During the operation period, these flexible main structures often need to adjust their forms according to different water flow conditions, water level changes, and engineering requirements. Therefore, devices capable of flexible adjustment are required to enable the flexible main structure to adapt to water level changes.

[0003] The existing adjustment devices mainly include the following types:

[0004] (1) The hinge device. The hinge device usually consists of a hinge shaft, a hinge seat, etc. The hinge seat is fixed to the corresponding foundation or structure by means of anchor bolts, etc. The hinge shaft is installed on a metal structure such as a gate, and then the hinge shaft is inserted into the bushing of the hinge seat, enabling the hinge shaft to rotate within a certain range to achieve actions such as opening and closing. This method has the following problems: it is easily affected by underwater attached debris in a water-related environment, prone to wear or running jams, affecting normal operation and shortening the service life.

[0005] (2) The sliding support. The sliding support mainly includes an upper sliding plate, a lower sliding plate, and an intermediate sliding material area. The lower sliding plate is fixed to the support structure, and the lower sliding plate is connected to the metal structure component that needs to move. The upper sliding plate slides relative to the lower sliding plate under the action of the intermediate sliding material, thereby achieving displacement adaptation;

[0006] (3) The sliding bearing. The sliding bearing mainly includes an inner ring, an outer ring, rolling elements, a cage, etc. The inner ring is installed on a rotating metal shaft, and the outer ring is fixed to the support structure. When the metal shaft rotates, the inner ring rotates relative to the outer ring, reducing friction and wear through the action of the sliding material, achieving smooth rotational motion, and adapting to the axial and radial displacements of the shaft to a certain extent;

[0007] The methods of the sliding support and the sliding bearing have the following problems: they bear high loads, are prone to local deformation or damage, thereby affecting the sliding effect and resulting in the inability to effectively release the flexible main structure.

[0008] (4) Expansion joint. An expansion joint generally consists of a corrugated pipe, flanges, tie rods, etc. It is connected between metal pipes or structures that need to accommodate displacement through flanges. When the length of the structure changes, the corrugated pipe will elongate or shorten accordingly to absorb the displacement. At the same time, the tie rods play a role in restricting the expansion range and maintaining the structural stability. The following problems exist in this method: It cannot meet large-scale adjustment, and the seals are prone to aging and damage, with a short service life, complex operation and maintenance, resulting in water leakage in the flexible main structure.

[0027] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. For the convenience of description, words such as "upper", "lower", "left", and "right" in the following text only represent the same directions as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0028] Embodiment 1

[0029] As Figures 1 - 3 shown, a sliding connection device provided in this embodiment includes a supporting wall 1 and an adjusting structure 12 that slides along the Z direction on the supporting wall 1. The supporting wall 1 has three directions of X, Y, and Z.

[0030] The adjustment structure 12 includes a chute 2, a slide rail 3, a pulley 4, a roller 5, a shovel plate 6, a first support 7, a clamping plate 8, a second support 9, a slot hole 10, and a through hole 11.

[0031] A chute 2 extending in the Z direction is provided in the support wall 1. A slot hole 10 penetrating in the X direction is provided on one side wall of the support wall 1, and the slot hole 10 communicates with the chute 2. As Figure 3 shown, a slide rail 3 is provided on the inner wall surface of the support wall 1 forming the chute 2.

[0032] Both ends of the roller 5 are rotatably provided (rotary connection can be achieved through bearings) with the pulleys 4, and the pulleys 4 are adapted to the chute 2 at both ends in the Y direction. The surface of the slide rail 3 is smooth and contacts the pulley 4 to reduce friction.

[0033] The first support 7 is disposed in the slot hole 10, and one end of the first support 7 is connected to the roller 5, and the other end of the first support 7 is connected to the shovel plate 6, and the shovel plate 6 is located outside the support wall 1. The first support 7 is disposed at both ends of the roller 5 in the Y direction (as Figure 2 shown).

[0034] The cross-section of the shovel plate 6 in the Y direction is a triangle with a thick middle and thin sides (as Figure 1 shown), or the shovel plate 6 is a wedge-shaped structure with a sharp corner, which can remove foreign objects (such as cutting waterweeds) encountered during the descent or ascent.

[0035] The clamping plate 8 is connected to the roller 5 through the second support 9. The clamping plate 8 is disposed at both ends of the roller 5 in the Z direction. The clamping plate 8 is located in the middle of the roller 5, and a through hole 11 is provided in the middle of the shovel plate 6. The towing rope on the flexible main body structure passes through the through hole 11 and is connected to the clamping plate 8.

[0036] The pulleys 4, the roller 5, the clamping plates 8, and the shovel plates 6 are all made of high-strength corrosion-resistant metal. During use, the pulleys 4, the roller 5, the clamping plates 8, and the shovel plates 6 drive the towing rope to slide downward along the slot hole 10 in the Z direction.

[0037] When the water level rises or falls, the flexible main body structure connected to the sliding connection device can adaptively change with the change of the water level.

[0038] Embodiment 2

[0039] During the construction of a certain reservoir in the upper reaches of a certain river, the average annual flow is 677 m 3 / s. After the reservoir is impounded, obvious temperature stratification appears in the reservoir area, resulting in the water temperature discharged in spring and summer being lower than that under natural conditions, which has an adverse impact on the spawning and reproduction of downstream fish. In order to enable fish to have suitable water temperature conditions during the spawning period, a composite enclosure device needs to be built upstream of the power station intake to increase the water temperature discharged from the power station.

[0040] The chute 2 in the support wall 1 has a length × width × height of approximately 19m × 0.5m × 0.7m. A metal slide rail 3 with a thickness of approximately 0.1m is preset in the chute body. A plurality of adjusting structures 12 are preset in the chute 2. Each adjusting structure 12 is composed of a pulley 4 and a roller 5, and is made of high-strength anti-corrosion metal. The diameter of the pulley 4 is approximately 0.5m. The plurality of adjusting structures 12 are respectively connected to different height positions of the flexible main structure, and the lower end of the flexible main structure is fixed by anchor bolts. The plurality of adjusting structures 12 connected to the flexible main structure can adaptively change with the water level change.

[0041] Through numerical simulation calculation and analysis, when the top flow-through height is 6m, the total load borne by the flexible enclosure curtain is 175t, and the maximum flow-through speed is approximately 2.2m / s; if the flexible enclosure curtain is adjusted to a top flow-through height of 8m, the total load borne by the flexible enclosure curtain is reduced to 95t, and the maximum flow-through speed is approximately 1.7m / s.

[0042] The sliding connection device provided by the present utility model can bear a high load, and can be flexibly adjusted, effectively reducing the load borne by the water retaining system, and has significant promotion value.

[0043] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
