Description

Technical Field

[0001] This utility model relates to the field of wave valve technology, specifically a high-stability explosion-proof wave valve. Background Technology

[0002] Blast wave ventilators are protective ventilation devices used in civil defense projects. They are mainly used to ensure uninterrupted ventilation inside the project and effectively block shock waves from entering the project in the event of air raids or shock waves. However, existing blast wave ventilators lack reliable operating mechanisms to control the opening and closing actions in practical applications where remote control or automated operation is required, which affects their performance and safety in complex environments. Utility Model Content

[0003] The purpose of this invention is to provide a highly stable explosion-proof wave valve to solve the problem mentioned in the background art that existing explosion-proof wave valves lack a reliable operating mechanism for controlling opening and closing actions in practical applications where remote control or automated operation is required, thus affecting their performance and safety in complex environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-stability explosion-proof valve, comprising:

[0005] Fixed frame;

[0006] Openings are equidistantly spaced inside the fixed frame.

[0007] A fixed side frame is symmetrically arranged on one side of a fixed frame. A rotating support rod is rotatably connected inside the fixed side frame, and a connecting side box is rotatably connected to the outside of the rotating support rod. One side of the connecting side box is fixedly connected to the fixed frame.

[0008] A fixed outer support plate is symmetrically arranged on the outside of the rotating support rod, and the fixed outer support plate is rotatably connected to the fixed side frame;

[0009] A fixed side seat is fixedly connected to one side of a fixed outer support plate. A wave-damping valve plate that mates with the opening is installed on one side of the fixed side seat by bolts.

[0010] A positioning groove is provided at the bottom of the wave-damping valve panel, and a positioning plate is provided below the positioning groove.

[0011] As a preferred embodiment of this utility model: a worm gear is rotatably connected inside the connecting side box, and a worm wheel is fixedly connected to the outside of the rotating support rod, with the worm wheel meshing with the worm gear.

[0012] As a preferred embodiment of this utility model: a motor is installed inside the connecting side box, and the output end of the motor is fixedly connected to the worm gear.

[0013] As a preferred embodiment of this utility model: a fixed side box is fixedly connected to one side of the fixed frame, and the positioning plate is slidably connected inside the fixed side box.

[0014] As a preferred embodiment of this utility model: a cylinder is installed inside the fixed side box, and the output end of the cylinder is fixedly connected to the positioning plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a worm, a worm wheel, and a rotating support rod, this utility model realizes that when the worm rotates, it drives the meshing worm wheel to rotate. When the worm wheel rotates, it drives the inner rotating support rod to rotate synchronously. When the rotating support rod rotates, it drives the outer fixed support plate to rotate. The fixed support plate drives the fixed side seat and the wave-damping valve plate to rotate, thereby adjusting the opening and closing of the wave-damping valve plate and handling the opening and closing of the wave-damping valve plate on the side of the passage. By setting up a cylinder and a positioning plate, the output end of the cylinder drives the positioning plate to move within the fixed side box. The positioning plate cooperates with the positioning bottom groove to improve the stability of the wave-damping valve plate when it is closed on the side of the fixed frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a high-stability explosion-proof valve, comprising: a fixed frame 1; openings 2 equidistantly located inside the fixed frame 1; fixed side frames 3 symmetrically fixedly connected to one side of the fixed frame 1, with a rotating support rod 4 rotatably connected inside the fixed side frame 3, and a connecting side box 8 rotatably connected to the outside of the rotating support rod 4, one side of the connecting side box 8 being fixedly connected to the fixed frame 1; fixed outer support plates 5 symmetrically fixedly connected to the outside of the rotating support rod 4, and the fixed outer support plates 5 being rotatably connected to the fixed side frames 3; a fixed side seat 6 fixedly connected to one side of the fixed outer support plate 5, with a wave-damping valve plate 7 that mates with the opening 2 installed on one side of the fixed side seat 6 by bolts; a positioning bottom groove 12 located at the bottom of the wave-damping valve plate 7, with a positioning plate 14 located below the positioning bottom groove 12, the positioning plate 14 mates with the positioning bottom groove 12 at the bottom of the wave-damping valve plate 7, further improving the stability of the wave-damping valve plate 7 when closed.

[0023] The internal rotatable connection of the connecting side box 8 is a worm gear 10, and the outer side of the rotating support rod 4 is fixedly connected to a worm wheel 9. The worm wheel 9 is meshed with the worm gear 10. When the worm gear 10 rotates, it drives the meshing worm wheel 9 to rotate. The worm wheel 9 drives the inner rotating support rod 4 to rotate and adjust. The rotation position of the fixed outer support plate 5, the fixed side seat 6, and the wave-damping valve plate 7 is adjusted by rotating the support rod 4.

[0024] The connecting side box 8 is equipped with a motor 11. The output end of the motor 11 is fixedly connected to the worm gear 10. The output end of the motor 11 drives the worm gear 10 to rotate and adjust. The motor 11 drives the meshing worm wheel 9 to rotate and adjust.

[0025] Among them, a fixed side box 13 is fixedly connected to one side of the fixed frame 1, and a positioning plate 14 is slidably connected inside the fixed side box 13. The positioning plate 14 slides within the fixed side box 13 to limit the movement, thereby improving the stability of the adjustment of the positioning plate 14.

[0026] The fixed side box 13 is equipped with a cylinder 15. The output end of the cylinder 15 is fixedly connected to the positioning plate 14. The output end of the cylinder 15 drives the positioning plate 14 to move up and down to adjust its position, so as to facilitate the limiting cooperation between the positioning plate 14 and the positioning bottom groove 12.

[0027] Specifically, in applications requiring remote control and automated operation, an external controller performs the operation. The output of motor 11 drives worm gear 10 to rotate, which in turn drives meshing worm wheel 9. The rotation of worm wheel 9 drives inner rotating support rod 4, which in turn drives outer fixed support plate 5. The fixed support plate 5 rotates and adjusts inside the fixed side frame 3. The fixed support plate 5 drives wave-damping valve plate 7 to rotate and adjust via fixed side seat 6, thus opening and closing the wave-damping valve plate 7. When the wave-damping valve plate 7 is in contact with one side of the fixed frame 1, the output of cylinder 15 drives positioning plate 14 to move upward. The output of positioning plate 14 enters the positioning groove 12 at the bottom of wave-damping valve plate 7, improving the stability of the wave-damping valve plate 7 when closed.
