[0033] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0034] Example 1:

[0035] See also Figure 1 A harmful gas sealing cover comprises a mounting plate 1, a sealing opening 2 is provided on the mounting plate 1, and the harmful gas sealing cover further comprises:

[0036] A cylinder 3 is provided on the lower end surface of the mounting plate 1;

[0037] A cover plate 4 is movably mounted on the upper end surface of the mounting plate 1 and matches the sealing port 2. The cover plate 4 is provided with a through hole, and a gas detector 5 is provided at the through hole.

[0038] The movable end of the cylinder 3 is movably connected to the cover plate 4 , and the cylinder 3 drives the cover plate 4 to move.

[0039] Specifically, a protrusion is provided on the edge of the sealing port 2, and a groove that fits with the protrusion is provided on the lower end surface of the cover plate 4. In this way, when the cover plate 4 is closed on the sealing port 2, the seal is tighter; the fixed end of the cylinder 3 is installed on the lower end surface of the mounting plate 1 and is installed avoiding the sealing port 2, and the movable end of the cylinder 3 is movably connected to the cover plate 4 through the sealing port 2; the cover plate 4 is movably installed on the upper end surface of the mounting plate 1, and the cover plate 4 can be rotated and raised and lowered.

[0040] Before opening, release the air first and use the gas detector 5 to detect whether there is any gas overflow. If there is no gas overflow, the movable end of the cylinder 3 is controlled to move, and the cover plate 4 is driven by the cylinder 3 to move, so that the cover plate 4 is separated from the sealing port 2, thereby realizing the opening of the sealing port 2; the closing of the sealing port 2 is the same, which will not be repeated here.

[0041] In this embodiment, the detection feedback of the gas detector 5 is used to control the movement of the cylinder 3, thereby realizing the opening and closing of the sealing port 2, avoiding the safety risk problems caused by manual operation.

[0042] Optionally, the gas detector 5 is a fixed gas detector.

[0043] Example 2:

[0044] See also Figures 1 to 4Based on embodiment 1, optionally, the movable end of the cylinder 3 is hinged with a driven rod 6, and the two ends of the driven rod 6 are hinged with a first traction rod 7, and the end of the first traction rod 7 away from the driven rod 6 is hinged to the lower end of the sealing port 2 through a hinge block 8.

[0045] Specifically, the driven rod 6 is disposed transversely below the sealing opening 2. The movable end of the cylinder 3 is hinged to the middle portion of the driven rod 6. The ends of the driven rod 6 are respectively hinged to the ends of the two first traction rods 7 that are away from the hinge block 8. The ends of the first traction rods 7 that are away from the driven rod 6 are hinged to the hinge block 8. The upper end of the hinge block 8 is fixedly connected to the lower end of the mounting plate 1. In this way, when the cylinder 3 is extended or retracted, it drives the driven rod 6 to move, causing the first traction rods 7 to rotate.

[0046] Optionally, a second traction rod 9 is hinged on the hinge block 8, and one end of the second traction rod 9 away from the hinge block 8 is hinged to the lower end surface of the cover plate 4;

[0047] When the first traction rod 7 moves, the second traction rod 9 is driven to move, so that the cover plate 4 moves.

[0048] Specifically, the hinge block 8 includes a fixed portion, a hinge shaft, and a sleeve. Since its structure is common knowledge, it is not labeled in the figure. The second traction rod 9 and the first traction rod 7 are both hinged to the hinge block 8. The end of the second traction rod 9, distal from the hinge block 8, is hinged to the lower end surface of the cover plate 4. As a result, when the first traction rod 7 rotates, the sleeve drives the second traction rod 9 to rotate synchronously, thereby pushing the cover plate 4 to open or close the sealing opening 2.

[0049] Optionally, a pair of connecting rods 10 are provided above the cover plate 4;

[0050] One end of the connecting rod 10 is hinged to the upper end surface of the cover plate 4 , and the other end is hinged to the upper end surface of the mounting plate 1 .

[0051] Specifically, the cover plate 4 is further supported by the connecting rod 10. At the same time, the connecting rod 10 and the cover plate 4 are hinged to ensure that the movement of the cover plate 4 can proceed smoothly without being affected.

[0052] Optionally, the connecting rod 10 is an L-shaped connecting rod.

[0053] Specifically, the connecting rod 10 is configured as an L-shaped connecting rod so that the cover plate 4 is not affected when flipping over, thereby ensuring that the movement of the cover plate 4 can continue.

[0054] Optionally, the second traction rod 9 has a curvature that matches the sealing port 2 .

[0055] Specifically, the second traction rod 9 is located inside the sealing opening 2 and does not contact the inner wall of the sealing opening 2. The second traction rod 9 has a curvature that matches the sealing opening 2, so that when the second traction rod 9 rotates on the plumb plane inside the sealing opening 2, it does not interfere with the inner wall of the sealing opening 2.

[0056] Optionally, the output end of the gas detector 5 is electrically connected to the controller, and the controller is electrically connected to the input end of the cylinder 3 .

[0057] Specifically, the controller receives the detection feedback of the gas detector 5 and then issues a control instruction to the cylinder 3 based on the feedback to control its operation. In this way, the control of the controller replaces the manual control, thereby realizing the automatic control of the sealing cover.

[0058] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0059] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
