[0002] A mine is the collective term for the shafts, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Inclined shafts, vertical shafts, and adit tunnels within underground mine development are sometimes also referred to as mines. Determining the scope, production capacity, and service life of each mine is a key consideration in mine design.
[0003] Well ventilation is a very important link in coal mines. The reliability and stability of air volume are related to the safety of the mine, and the air door is an indispensable part of this link.
[0004] The balanced dampers generally used inside tunnels cannot intuitively determine whether they need to be opened and to what angle, which will have a great impact on the progress of the project. Summary of the Invention
[0005] The object of the present invention is to provide a zero-damping balanced damper to solve the problems raised in the above background technology.

[0008] The zero-damping balanced damper system includes a system mainboard, the output signal of the system mainboard is connected to the wind speed meter, the output signal of the wind speed meter is connected to the damper, the output signal of the damper is connected to the motor signal, the output end of the motor signal is connected to the external controller signal, the wind speed meter is fixedly set on the outer surface of the damper body, the motor signal is fixedly set on the surface of the motor, and the signal end of the motor is connected to the signal end of the motor signal.
[0009] Through the above technical solution, when in use, the wind speed inside the tunnel is measured by the action of an external anemometer. When the wind speed reaches the set value, the anemometer sends a signal to the inside of the damper. At this time, the damper disperses energy and limits sound waves through friction and heat generation, causing moisture to accumulate in the sound guide tube, affecting the medium-frequency response, and is used to prevent damage to the device or pipeline due to interference forces. When external interference forces occur, the damper absorbs the impact force and reduces the vibration caused by the impact. Then, synchronously, the motor starts and then drives the first rotating column to rotate, so that the driven disk can be driven to rotate through the transmission belt. The driven disk can drive the second rotating column to rotate due to its own rotation, and can drive the damper body to open and close.
[0010] Preferably, the motor is a forward and reverse rotating motor.
[0011] Through the above technical solution, the motor is a forward and reverse motor that can drive the second rotating column to rotate forward and reverse, thereby driving the damper body to rotate inward and outward, thereby controlling the balance of the damper.
[0012] Preferably, fixed circular plates are fixedly provided on both side surfaces of the protective frame, and fixed rings are fixedly provided on the outer surfaces of the fixed circular plates. The fixed rings are fixed to the fixed circular plates, and the surface of the fixed rings is provided with a plurality of integrally formed fixing holes, and the spacing between the plurality of fixing holes is the same.
[0013] Through the above technical solution, the entire protective frame can be fixed inside the tunnel by the fixed circular plate, and the fixing ring and the fixing hole can be used to tightly fix the entire protective frame inside the tunnel. The outer shape of the protective frame is the same as the shape of the tunnel interior. This makes it easier to control the wind force inside the tunnel.
[0014] Preferably, a fixing plate is fixedly provided on the upper surface of the protective frame away from the damper. The fixing plate and the protective frame are integrally formed. Integrally formed through holes are provided at both ends of the surface of the fixing plate, and a shock-absorbing ring is fixedly provided at the outer edge of the through hole.
[0015] Through the above technical solution, the shock-absorbing ring can be used to facilitate the external machine to pull out the entire protective frame, making it convenient to maintain the entire protective frame.
[0016] Preferably, a clamping plate is provided on one side of the fixing plate close to the shock-absorbing ring, an integrally formed rubber plate is provided on the bottom of the clamping plate, and the clamping plate is connected to the protective frame through the rubber plate.
[0017] Preferably, both ends of the surface of the splint are provided with integrally formed fixing through holes.
[0018] Preferably, a pad is fixedly provided at an outer edge of a surface of one side of the fixing through hole close to the fixing plate.
[0019] Preferably, the number of the dampers is two, and the two dampers correspond to the two damper bodies.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This zero-damping balanced damper measures the wind speed inside the tunnel through the action of an external anemometer. When the wind speed reaches the set value, the anemometer sends a signal to the inside of the damper. At this time, the damper disperses energy and limits sound waves through friction and heat generation, causing moisture to accumulate in the sound-conducting tube, affecting the mid-frequency response, and is used to prevent damage to the device or pipeline due to interference forces.
[0022] This zero-damping balanced damper, when external interference force occurs, the damper absorbs the impact force and reduces the vibration caused by the impact. Then, synchronously, the motor starts and then drives the first rotating column to rotate, so that the driven disk can be driven to rotate through the transmission belt. The driven disk can drive the second rotating column to rotate due to its own rotation, and can drive the damper body to open and close.
[0023] This zero-damping balanced damper uses a fixed circular plate to secure the entire protective frame inside the tunnel, while a fixed ring and fixed holes allow the entire protective frame to be tightly fixed inside the tunnel. The outer shape of the protective frame is the same as the shape of the tunnel interior, making it easier to control wind force inside the tunnel.
[0024] The zero-damping balanced damper can facilitate an external machine to pull out the entire protective frame through the function of the shock-absorbing ring, thereby facilitating maintenance of the entire protective frame. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the damper 16 disperses energy and limits sound waves through friction and heat generation, so that moisture gathers in the sound guide tube, affecting the medium frequency response.
[0034] Preferably, the motor 5 is a forward and reverse motor 5. The motor 5 can drive the second rotating column 2 to rotate forward and reverse, thereby driving the damper body 15 to rotate inward and outward, thereby controlling the balance of the damper.
