Description

Technical Field

[0001] This utility model relates to the field of channel lining technology, specifically a channel lining device for water conservancy projects. Background Technology

[0002] Canal lining frost protection refers to measures to prevent the canal lining layer from being damaged by the frost heave of the foundation soil. The mechanism of frost damage to canal lining is as follows: in seasonally frozen soil areas, the moisture in fine soil condenses into ice crystals under sub-zero winter temperatures, which expand in volume, and the soil volume also expands accordingly, causing the ground to bulge. This phenomenon is called soil frost heave.

[0003] For example, patent document CN 221567032 U discloses a channel lining device, including a channel body. One side of the channel body has a pre-lined surface, and another surface to be lining is located on the side of the pre-lined surface. The channel body has banks on both sides of its upper end, and an auxiliary lining mechanism is located at the upper end of each bank. The auxiliary mechanism includes a fixed frame, a column, a crossbeam, and rollers. The fixed frame is located at the upper end of the bank, with a column fixedly mounted in the middle of its upper end. A crossbeam is fixedly mounted at the upper end of the column. Rollers are movably mounted on both sides of the lower end of the fixed frame via rotating shafts. A smoothing mechanism is located at the lower end of the crossbeam. This invention has good performance; the smoothing mechanism allows for quick smoothing of the cement surface after workers have laid the cement bricks, thus greatly improving the efficiency of channel lining.

[0004] However, in actual use, due to its own structural limitations, this structure can only be customized and connected to the channels of water conservancy projects to complete the channel lining. In actual use, the internal dimensions of the channel are often inconsistent, making it impossible to quickly adapt and move for connection. At the same time, the equipment cannot perform the limiting and compaction operation of all the tiles in the channel lining, which cannot meet the daily use needs. Therefore, it is urgent to design a channel lining device for water conservancy projects to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a channel lining device for water conservancy projects, in order to solve the problems mentioned in the background art. Due to the limitations of its own structure, the existing structure can only be customized and connected according to the channel of the water conservancy project in order to complete the channel lining. In actual use, the internal dimensions of the channel are often inconsistent, making it impossible to quickly adapt and move for connection. At the same time, the device cannot perform the limiting and compaction operation of all the tiles for channel lining, which cannot meet the daily use needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a channel lining device for water conservancy projects, comprising a bottom support, an air control seat fixedly connected to the front of the bottom support, an air control pump provided on the surface of the air control seat, adjustment components provided on both sides of the bottom support, and a moving component provided on one side of the adjustment components;

[0007] The adjustment assembly includes a movable pivot, and movable pivots are provided on both sides of the base bracket. Side brackets are movably connected to both sides of the base bracket through the movable pivots.

[0008] The movable component includes a support frame, and one side of the side support is fixedly connected to the support frame.

[0009] Preferably, a shrink cover is fixedly connected to the surface of the support frame, and lifting push rods are provided at both ends of the surface of the shrink cover.

[0010] Preferably, the interior of the shrink cover is movably connected to a telescopic seat via a lifting push rod, and the bottom of the telescopic seat is provided with casters.

[0011] Preferably, the bottom end of the support frame is provided with a support base.

[0012] Preferably, the inner wall of the side support is provided with a side airbag, and the inner wall of the side airbag is provided with a side pressure plate.

[0013] Preferably, the inner wall of the base support is provided with a central airbag, and the inner wall of the central airbag is provided with a central pressure plate.

[0014] Preferably, the bottom bracket is adapted to the side brackets and support frames on both sides.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This channel lining device for water conservancy projects, through its base support, movable shaft, side supports, support frame, contraction hood, lifting push rod, telescopic seat, moving wheels, and support base, enables the equipment to perform channel lining operations adapted to water conservancy projects. In actual use, the operator first places the base support at the bottom of the water conservancy project's channel. Then, the side supports on both sides can be rotated and adjusted at the movable shaft of the base support to adapt to the channel. The trapezoidal frame structure formed by the base and side supports provides material limiting for channel lining. Simultaneously, the lifting push rod on the surface of the contraction hood can be activated to extend and retract the telescopic seat and moving wheels inside the contraction hood, allowing the base and side supports to move within the channel. When the telescopic seat and moving wheels retract, the support frame, in conjunction with the support base at the bottom, provides overall support and fixation, completing the channel lining work more efficiently and demonstrating the practicality of the equipment design.

[0017] This channel lining device for water conservancy projects, through its base support, air control seat, air control pump, side supports, side airbags, side pressure plates, central airbag, and central pressure plate, further improves the overall performance of the equipment. During daily use, operators can activate the air control pump on the front air control seat of the base support to inflate the base, causing the central airbag on the inner wall of the base to inflate. This inflates the central pressure plate on the inner wall, compacting the lining material at the bottom of the channel. Simultaneously, the side airbags on the inner walls of the side supports also inflate and expand synchronously, with their inner side pressure plates compacting the lining material on the sides of the channel. This ensures a more stable channel lining operation, demonstrating the comprehensiveness of the equipment design. Attached Figure Description
