[0002] 70% of my country's metal deposits are mined underground, which is relatively dangerous. Poisoning and suffocation accidents have always been a common accident in underground mining of non-coal mines. The damper is an important facility in the mine ventilation system. First, it can prevent a large amount of toxic and harmful gases from invading and spreading to other well-ventilated workplaces, limit the toxic and harmful gases to local areas, and then introduce the toxic and harmful gases into the return air lane of the ventilation system to effectively prevent personnel from being poisoned and causing casualties. Second, the airflow regulation function can be achieved by opening or closing the damper.

[0003] At present, the following problems exist: 1. The mine air is equipped with cables, water pipes and other facilities, and these pipes all need to pass through the damper. One of the reasons for the complex design of the damper structure is that it is necessary to avoid the above facilities, resulting in slow installation efficiency and high installation cost. Problems; 2. When the damper is opened against the wind, the wind resistance is large, which makes it difficult to open the damper; 3. The working conditions in the mine are complicated, and power outages occur from time to time. At present, the automatic damper has the problem that it is difficult or impossible to open it manually when the power is off. Summary of the invention

[0021] In order to make the purpose and technical solution of the present invention clearer, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0022] like Figure 1 to Figure 3A multi-purpose high-efficiency damper for a main lane shown in the figure comprises: a bracket 1, fixed on the ground and the wall, the bracket 1 comprises an upper bracket 11 and a side bracket 12; a front bracket 111 of the upper bracket 11 is provided with a through slot, a chain 2 is provided in the through slot; a power device 3 is installed on the upper end of the bracket 1; a transmission box 4 is installed on the upper end of the bracket 1, connected to the power device 3, and drives the chain 2 to run through a gear structure (not shown in the figure, and the gear chain connection structure is a conventional design); the transmission box 4 includes an electromagnetic clutch (not shown in the figure); a door leaf 5 is movably installed on the upper bracket 11 through a connecting sleeve 6;

[0023] A connecting piece 61, a pulley block 62 and a sleeve 63 are provided in the connecting sleeve 6, and the connecting piece 61 connects and fixes the door leaf 5 and the chain 2; the pulley block 62 is provided between the connecting sleeve 6 and the upper bracket 11, and the sleeve 63 wraps and fixes the connecting piece 61 and the pulley block 63; the two sides of the through groove of the upper bracket form the track of the pulley block; the sleeve 63 fixes the connecting piece 61 by welding or bolts, and the sleeve 63 fixes the pulley block 62 by bolts; a controller (not shown in the figure), the controller is used to control the operation of the power device.

[0024] Preferably, the door leaf 5 is also provided with a pedestrian door 7; the pedestrian door 7 is translated by a lateral shifting device; a connecting device is provided between the pedestrian door 7 and the door leaf 5; the door leaf 5 is provided with a cavity for accommodating the pedestrian door 7 during lateral shifting; the door leaf 5 is provided with a slide rail 51 above the pedestrian door, and the pedestrian door 7 is fixed above by a pulley 71, and the pulley 71 runs on the slide rail 51.

[0025] Preferably, the door leaf 5 is provided with slideways 52 at the upper and lower parts of the pedestrian door 7 ; the pedestrian door 7 is provided with a plurality of flat wheels 72 , and the flat wheels 72 run on the slideways 52 .

[0026] Preferably, the switch device is a rotary door handle lock (not shown in the figure).

[0027] Preferably, a slide groove is further provided on the rear frame 112 of the upper bracket, and a plurality of sliders 53 are arranged inside. Each of the sliders is fixedly connected to a support frame 54, and the other end of the support frame 54 is fixed at the middle position of the door leaf 5 in the vertical direction.

[0028] Preferably, a plurality of reinforcing ribs 55 are provided on the door leaf 5 .

[0029] Preferably, the power device is an explosion-proof motor.

[0030] Preferably, the controller is a PLC controller.

[0031] Preferably, the two front brackets 121 of the side bracket are placed vertically for easy fixation to the wall, and a number of connecting frames are directly provided between the front bracket and the rear bracket. The two rear brackets 122 are arranged to be tilted backward so that the bracket is a right-angled trapezoid when viewed from the side. This design allows the bracket to occupy a larger area and be more stable to install, providing better support for the door leaf.

[0032] The traditional damper opens and closes on both sides, and the cables and water pipes need to be arranged in a detour; the design of the present invention is as follows Figure 2 As shown, the cable through hole 81 and the water pipe through hole 82 are at the damper, and the damper does not need to give way when opening and closing, so that cables, water pipes and other equipment do not need to be arranged in a detour.

[0033] The installation method of the present invention is as follows: 1. Fix the bracket on the ground and the wall; 2. Then install the motor, the transmission box and the gear chain structure, and install the connecting device; 3. Fix the door leaf on which the pedestrian door is installed on the connecting piece of the connecting device; 4. Weld one end of a plurality of support frames to the door leaf, and the other end to the corresponding slider.

[0034] The use process of the present invention is as follows: the motor is controlled to drive the chain to rotate and the door leaf to open at the same time. When closing the door, the motor is controlled to reverse to complete the closing action. When a pedestrian needs to pass through, he only needs to rotate the door handle to open it. When the power is off, the pedestrian door is not affected because it is opened manually and mechanically. The door leaf is separated from the motor when the power is off because an electromagnetic clutch is installed in the transmission box. The sliding door leaf will not be hindered by the motor and can be easily opened and closed manually.

[0035] The design principles of the present invention are: 1. The connecting sleeve design allows the weight of the door leaf to be borne by the bracket through the pulley block. The pulley block is used to reduce the friction of the opening and closing movement, making it convenient to open and close. In addition, the chain is only responsible for the left and right opening and closing of the door leaf, and does not bear the weight of the door leaf, so it is more durable; 2. The design of the support frame allows the door leaf to be fixed at both the top and the middle. Compared with the traditional method of fixing only on the top, it will not be shaken by the wind; 3. An electromagnetic clutch is provided, so that the door leaf can be manually opened and closed during a power outage; 4. The flat wheel design at the pedestrian door avoids the problem of difficulty in opening due to wind resistance.
