Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a trench cover structure. Background Technology

[0002] In the photovoltaic field, the production of silicon wafers requires multiple processes such as electrolysis, cleaning, and drying. These processes are usually carried out in tanks such as electrolytic cells, cleaning tanks, and drying tanks. In particular, for electrolytic cells and drying tanks, in order to prevent the leakage of acidic gases generated during electrolysis, and to improve the drying effect during drying, a cover structure is required on the top of the tank to cover the opening of the tank.

[0003] The existing sliding cover structure uses pulleys at the four corners of the cover for support, and guide wheels between the cover and the frame to guide the movement of the cover. The movement of the cover is controlled by linear mechanisms such as cylinders. However, due to the gap between the guide wheels and the frame, deviations are prone to occur during the movement of the cover, resulting in jamming during the extension and retraction of the cylinder. Utility Model Content

[0004] The present invention aims to solve one of the problems existing in the background art.

[0005] Therefore, this utility model provides a groove cover structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A slot cover structure, comprising,

[0008] Mounting frame, and cover body that moves along the plane of the mounting frame within the mounting frame;

[0009] A sliding assembly for controlling the movement of the cover, the sliding assembly comprising:

[0010] A guide plate is disposed within the mounting frame and is positioned along the sliding direction of the cover.

[0011] The guide wheel is mounted on the cover, and its axial direction is perpendicular to the plane of the mounting frame. The guide wheel is clamped on both sides of the guide plate and rolls with the guide plate.

[0012] Furthermore, multiple guide wheels are provided along the extension direction of the guide plate.

[0013] Furthermore, the mounting frame includes two opposing fixed frames and a guide frame disposed between the fixed frames. There are two guide frames, which are respectively disposed at both ends of the fixed frames. The length direction of the guide frame is arranged along the moving direction of the cover, and the guide plate is connected to the opening of the guide frame.

[0014] Furthermore, both the fixing frame and the guide frame are configured as U-shaped frames, with the openings of the fixing frame and the guide frame facing the interior of the mounting frame. The number of guide frames at one end of the fixing frame is adapted to the number of covers, and multiple fixing frames are stacked perpendicular to the plane of the mounting frame.

[0015] Furthermore, the sliding assembly also includes a cylinder, which is fixedly connected to the outer wall of the guide frame where the corresponding cover is located by a stiffener. The output end of the cylinder is connected to the cover by a connecting plate, the connecting plate passes through the guide frame, and the guide frame is provided with a guide slot for the connecting plate to pass through.

[0016] Furthermore, the cylinder is fixedly connected to the outer wall of the guide frame where the corresponding cover is located by a stiffening plate, and the stiffening plate is set at the front and rear ends of the cylinder body.

[0017] Furthermore, the sliding assembly also includes support wheels, which are located at the four corners of the cover and roll in cooperation with the guide frame.

[0018] The beneficial effect of this utility model is that by setting a guide plate inside the guide frame, and having two guide wheels clamped on both sides of the guide plate and rolling with it to form a double-sided guide bearing, and combined with the support wheel, the cylinder extension and retraction are prevented from jamming, ensuring that the cover runs smoothly along the plane of the mounting frame.

[0029] A groove cover structure includes a mounting frame 1, a sliding component 2, and a cover 3. The cover 3 is disposed above the groove through the mounting frame 1. The sliding component 2 is connected to the mounting frame 1 to control the cover 3 to move horizontally within the mounting frame 1. In this embodiment, two covers 3 are disposed within the mounting frame 1, and the number of sliding components 2 is adapted to the number of covers 3.

[0030] The mounting frame 1 is welded from SUS304 square tubing and stainless steel sealing plates. Specifically, the mounting frame 1 includes two opposing fixed frames 11 and a guide frame 12 positioned between the fixed frames 11. The fixed frames 11 are welded to the top of the tank. Two guide frames 12 are provided, respectively positioned at both ends of the fixed frames 11. The length direction of the guide frames 12 is along the moving direction of the cover 3. The fixed frames 11 and guide frames 12 are fixedly connected to each other to form a quadrilateral mounting frame 1 with four right angles.

[0031] The cross-section of the fixing frame 11 is U-shaped, and the openings of the two fixing frames 11 are arranged opposite each other. The end of the guide frame 12 is inserted into the opening of the fixing frame 11. Multiple guide frames 12 are arranged vertically at the same end of the fixing frame 11. In this embodiment, there are two covers 3, which are matched with the number of covers 3. Two guide frames 12 are stacked at the same end of the fixing frame 11. The guide frames 12 are also U-shaped. The opening of the guide frame 12 is set towards the center line of the two fixing frames 11. The two ends of one cover 3 are inserted into the opening of the upper guide frame 12, and the two ends of the other cover 3 are inserted into the opening of the lower guide frame 12. Two sliding components 2 are used to control the horizontal movement of the two covers 3. The sliding components 2 can be set on the same side of the mounting frame 1 or on opposite sides of the mounting frame 1. The sliding components 2 are set on the outside of the two guide frames 12. In this embodiment, in order to balance the weight, the two sliding components 2 are symmetrically arranged in the horizontal plane with the center line of the guide frame 12 as the axis of symmetry.

[0032] Taking a sliding assembly 2 as an example, the sliding assembly 2 includes a cylinder 21, a connecting plate 23, a guide wheel 25, and a support wheel 26. The cylinder 21 is fixedly connected to the outer wall of the guide frame 12 where the corresponding cover 3 is located by a stiffener. The stiffener is set at the front and rear ends of the cylinder body. The connecting plate 23 is connected to the output shaft of the cylinder 21. The corresponding guide frame 12 is provided with a guide groove 14, and the connecting plate 23 passes through the guide groove 14 and connects to the corresponding cover 3. Preferably, a speed regulating valve can be provided on the cylinder 21 to control the speed of movement of the cover 3.

[0033] A guide plate 13 is provided in the corresponding guide frame 12 near the cylinder 21. The guide plate 13 is a sheet metal 22 arranged along the length of the guide frame 12. The guide wheel 25 is connected to one side of the cover 3 through the mounting plate 24. Multiple mounting plates 24 can be arranged along the length of the guide plate 13. Each mounting plate 24 has two guide wheels 25. The axial direction of the guide wheel 25 is perpendicular to the plane of the mounting frame 1. The two guide wheels 25 are located on both sides of the guide plate 13 and clamp the guide plate 13 to form a double-sided guide bearing structure. Support wheels 26 are arranged at the four corners of the cover 3. Specifically, the support wheels 26 are arranged at both ends of the cover 3 along the moving direction of the cover 3, and there are two support wheels 26 at each end of the cover 3. The support wheels 26 at the ends of the cover 3 are in rolling cooperation with the guide frames 12 on both sides of the cover 3.

[0034] In this application, the guide wheel 25 and the guide plate 13 form a double-sided guide bearing, and together with the support wheel 26, the cover 3 runs smoothly along the plane of the mounting frame 1, avoiding the jamming phenomenon of the cylinder 21 extending and retracting.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
