Description

Technical Field

[0001] This utility model relates to the field of pressureless dampers, and in particular to an electrical control device for pressureless dampers. Background Technology

[0002] Pressureless air doors are a type of air door equipment widely used in ventilation systems in mines, tunnels, underground engineering, etc. Its core feature is that it relies on the air pressure difference in the ventilation system to achieve automatic balance, without consuming a lot of extra energy to resist the air pressure to open or close. It is mainly used to separate different ventilation areas, control the airflow direction, and ensure that the ventilation parameters (such as air volume and air pressure) of each area meet the production safety requirements, while facilitating the passage of personnel and vehicles between different areas.

[0003] However, most existing pressureless doors use manual opening or single-sensor control. Manual opening requires active operation by personnel or vehicles, which not only increases the operational burden but may also affect passage efficiency due to untimely operation. This is especially true in complex environments such as mines and tunnels, where it can easily lead to safety hazards. Furthermore, single-sensor control is prone to sensor failure in harsh environments, causing the door to fail to open properly or open incorrectly, seriously affecting its reliability. Secondly, when the door closes, most existing pressureless doors do not have a dedicated buffer component or only use simple rubber pads for cushioning. Their working principle is that they can only absorb a small amount of impact force through the elastic deformation of the rubber pads, resulting in violent collisions between the door and the door frame when closing. This not only generates a lot of noise but also causes mechanical damage to the door and the door frame, reducing the overall stability of the equipment. To solve the above problems, we propose an electrical control device for pressureless doors. Utility Model Content

[0004] The main objective of this invention is to provide a pressureless damper electrical control device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pressureless damper control device includes a base plate, a device door frame fixedly connected to the top of the base plate, a first damper leaf and a second damper leaf rotatably connected to the inner side of the device door frame, a drive assembly at the rear end of each of the first and second damper leaves, a limiting block fixedly connected to the inner side of the device door frame at the front of each of the first and second damper leaves, a buffer assembly between each of the first and second damper leaves and the corresponding limiting block, two railings fixedly connected to the front end of the base plate, a pressure sensing pedal installed on the top of the base plate between the two railings, and symmetrical laser beam sensors installed on the adjacent sides of the two railings.

[0006] Preferably, the drive assembly includes an electric cylinder located on the outside of the equipment door frame. The output end of the electric cylinder is fixedly connected to a second rotating seat, and the outside of the second rotating seat is rotatably connected to a mounting seat. The mounting seat is fixedly installed at the rear end of the corresponding first and second damper leaves.

[0007] Preferably, two mounting brackets are fixedly installed on the outer side of the equipment door frame, and a first rotating seat is fixedly connected to the rear end of each of the two mounting brackets. The two first rotating seats are respectively rotatably connected to the corresponding electric cylinder.

[0008] Preferably, a rotating sleeve is fixedly connected to the opposite ends of the first and second air dampers, and a rotating shaft is fitted inside the rotating sleeve. Both the upper and lower ends of the rotating shaft are fixedly connected to the inner side of the equipment door frame.

[0009] Preferably, both the first and second damper panels are fixedly connected to sliders at their bottom ends, and the top of the base plate has two sliding grooves corresponding to the sliders, with the two sliders slidably connected to the inner side of the corresponding sliding grooves.

[0010] Preferably, the buffer assembly includes a mounting plate, which is fixedly connected to the rear end of the limiting block. A guide telescopic column is fixedly connected to the rear end of the mounting plate, and a magnetic block is fixedly connected to the other end of the guide telescopic column. The magnetic block is adapted to the corresponding first and second air damper. Elastic components are provided at the four corners of the rear end of the mounting plate.

[0011] Preferably, the elastic component includes a first rotating component, which is fixedly connected to the mounting plate. A telescopic rod is rotatably connected to the inner side of the first rotating component, and a second rotating component is rotatably connected to the other end of the telescopic rod.

[0012] Preferably, a buffer spring is sleeved on the outer side of the telescopic rod, and the two ends of the buffer spring are fixedly connected to the ends of the first rotating assembly and the second rotating assembly respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This pressureless damper control device uses a pressure-sensing pedal at the front end of the base plate and a laser beam sensor on the railing to form a dual-sensing trigger mechanism. When personnel or vehicles approach, a start command is sent to the drive component. This dual-sensing design not only avoids the problem of sensor failure or false triggering that is prone to occur in harsh environments due to single sensing, but also eliminates the need for manual operation by personnel or vehicles, greatly reducing the operational burden and improving traffic efficiency. 2. In the process of closing the pressureless damper, the damper leaf first adheres to the magnetic block in the buffer assembly for initial positioning. Then, the guide telescopic column provides stable guidance, and the elastic components at the four corners of the mounting plate work synchronously. The telescopic rod retracts adaptively with the pressure of the damper leaf, and the buffer spring on its outer side absorbs the impact force when the damper leaf closes through elastic deformation, avoiding direct and violent collision between the damper leaf and the door frame, reducing mechanical wear between the damper leaf and the door frame, and ensuring the long-term stability of the pressureless damper.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-5As shown, a pressureless damper control device includes a base plate 1. A device door frame 2 is fixedly connected to the top of the base plate 1. A first damper 3 and a second damper 4 are rotatably connected to the inner side of the device door frame 2. A drive assembly is provided at the rear end of both the first damper 3 and the second damper 4. A limiting block 19 is fixedly connected to the inner side of the device door frame 2 at the front of both the first damper 3 and the second damper 4. A buffer assembly is provided between the first damper 3 and the second damper 4 and the corresponding limiting block 19. Two railings 7 are fixedly connected to the front end of the base plate 1. A pressure sensing pedal 5 installed at the top of the base plate 1 is provided between the two railings 7. A symmetrical laser beam sensor 8 is installed on the side of the two railings 7 that are close to each other.

[0018] In this embodiment, the drive assembly includes an electric cylinder 11, which is located on the outside of the equipment door frame 2. The output end of the electric cylinder 11 is fixedly connected to a second rotating seat 12. The outer side of the second rotating seat 12 is rotatably connected to a mounting seat 13. The mounting seat 13 is fixedly installed at the rear end of the corresponding first damper 3 and second damper 4. Two mounting brackets 9 are fixedly installed on the outside of the equipment door frame 2. The rear end of each of the two mounting brackets 9 is fixedly connected to a first rotating seat 10. The two first rotating seats 10 are rotatably connected to the corresponding electric cylinder 11.

[0019] Specifically, when a worker approaches the first air door 3 and the second air door 4, the worker will first step on the pressure-sensing pedal 5 at the top of the base plate 1, located between the two railings 7. At this time, the symmetrical laser beam sensors 8 installed on the side of the two railings 7 that are close to each other will simultaneously detect the target. Both can send start signals to the drive component. When the pressure-sensing pedal 5 and the laser beam sensor 8 are emitting signals, the signal receiving controller can only receive one electrical signal in a short time. Therefore, the simultaneous emission of start signals by the pressure-sensing pedal 5 and the laser beam sensor 8 will not cause signal disorder, preventing damage to either the pressure-sensing pedal 5 or the laser beam sensor 8, and ensuring the normal operation of the pressureless air door electrical control device. At this time, the first rotating seat 10 fixed to the rear end of the two mounting brackets 9 on the outside of the equipment door frame 2 provides rotational support for the electric cylinder 11. After the electric cylinder 11 is started, its output end drives the second rotating seat 12 to retract. The second rotating seat 12 drives the mounting seat 13 that is rotatably connected to it, thereby driving the first air door 3 and the second air door 4, which are fixed to the mounting seat 13, to rotate backward.

[0020] In this embodiment, a rotating sleeve 16 is fixedly connected to the opposite ends of the first damper 3 and the second damper 4. A rotating shaft 15 is sleeved on the inner side of the rotating sleeve 16. The upper and lower ends of the rotating shaft 15 are fixedly connected to the inner side of the equipment door frame 2. A slider 17 is fixedly connected to the bottom end of the first damper 3 and the second damper 4. Two sliding grooves 18 corresponding to the sliders 17 are opened at the top of the base plate 1. The two sliders 17 are slidably connected to the inner side of the corresponding sliding grooves 18.

[0021] Specifically, at this time, the rotating sleeve 16, which is fixed at one end of the first air door 3 and the second air door 4, rotates around the rotating shaft 15 fixed inside the equipment door frame 2, and the sliders 17 fixed at the bottom ends of the two slide in the corresponding sliding grooves 18 opened at the top of the base plate 1, thereby ensuring that the door rotates smoothly to open the door.

[0022] In this embodiment, the buffer assembly includes a mounting plate 20, which is fixedly connected to the rear end of the limiting block 19. A guide telescopic column 21 is fixedly connected to the rear end of the mounting plate 20, and a magnetic block 26 is fixedly connected to the other end of the guide telescopic column 21. The magnetic block 26 is adapted to the corresponding first damper 3 and second damper 4. Elastic components are provided at the four corners of the rear end of the mounting plate 20. The elastic components include a first rotating component 22, which is fixedly connected to the mounting plate 20. A telescopic rod 24 is rotatably connected to the inner side of the first rotating component 22, and a second rotating component 23 is rotatably connected to the other end of the telescopic rod 24. The second rotating component 23 is fixedly connected to the magnetic block 26. A buffer spring 25 is sleeved on the outer side of the telescopic rod 24, and the two ends of the buffer spring 25 are fixedly connected to the ends of the first rotating component 22 and the second rotating component 23 that are close to each other.

[0023] Specifically, both the first damper 3 and the second damper 4 are made of metal. When the staff passes through and the door needs to be closed, the output end of the electric cylinder 11 extends and drives the door to move in the opposite direction until the damper approaches the limiting block 19 fixed inside the equipment door frame 2. At this time, the two dampers first attract the corresponding magnetic blocks 26 for initial positioning, and then the guide telescopic column 21 plays a guiding role. At the same time, the elastic components at the four corners of the rear end of the mounting plate 20 play a buffering role. The first rotating component 22 and the second rotating component 23 in the elastic component cooperate to make the telescopic rod 24 retract adaptively. At the same time, the elastic deformation of the buffer spring 25 sleeved on the outside of the telescopic rod 24 absorbs the impact force when the door closes, and finally realizes the smooth and impact-free closing of the door, thus completing one damper control cycle.

[0024] More specifically, the pressure sensing pedal 5, laser beam sensor railing 8, and electric cylinder 11 in this solution are all commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this paper. Furthermore, the pressure sensing pedal 5 and laser beam sensor railing 8 are electrically connected to the electric cylinder 11 via a controller. Those skilled in the art are familiar with their working principles and can apply them proficiently. Therefore, this paper will not elaborate further. This solution aims to protect the physical structure, but does not protect the circuitry and software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0025] It should be noted that this utility model is a pressureless damper electrical control device. During operation, when a person approaches the first damper leaf 3 and the second damper leaf 4, the person will first step on the pressure-sensing pedal 5 located at the top of the base plate 1 between the two railings 7. At this time, the symmetrical laser beam sensors 8 installed on the side of the two railings 7 closest to each other will simultaneously detect the target. Both can send a start signal to the drive assembly, preventing damage to either the pressure-sensing pedal 5 or the laser beam sensor 8, and ensuring the normal operation of this pressureless damper electrical control device. At this time, the first rotating seat 10, fixed to the rear end of the two mounting brackets 9 on the outside of the equipment door frame 2, provides rotational support for the electric cylinder 11. After the electric cylinder 11 starts, its output end drives the second rotating seat 12 to retract. The second rotating seat 12 drives the mounting seat 13 rotatably connected to it, thereby driving both the first damper leaf 3 and the second damper leaf 4, which are fixed to the mounting seat 13, to rotate backward. At this time, the first damper leaf 3 and the second damper leaf 4 are at opposite ends. The fixed rotating sleeve 16 rotates around the rotating shaft 15 fixed inside the equipment door frame 2, and the slider 17 fixed at the bottom of both slides in the corresponding sliding groove 18 opened at the top of the base plate 1, thereby ensuring that the door rotates smoothly to open the door. When the door needs to be closed after the staff passes through, similarly, the output end of the electric cylinder 11 extends to drive the door to move in the opposite direction until the door is close to the limiting block 19 fixed inside the equipment door frame 2. At this time, the two door panels first attract the corresponding magnetic block 26 for initial positioning, and then the guide telescopic column 21 plays a guiding role. At the same time, the elastic components at the four corners of the rear end of the mounting plate 20 play a buffering role. The first rotating component 22 and the second rotating component 23 in the elastic component cooperate to make the telescopic rod 24 retract adaptively. At the same time, the elastic deformation of the buffer spring 25 sleeved on the outside of the telescopic rod 24 absorbs the impact force when the door is closed, and finally realizes the smooth and impact-free closing of the door, thus completing one door control cycle, which is quite practical.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
