Description

Technical Field

[0001] This utility model relates to the field of mining ventilation technology, and more specifically, to a ventilation device that is easy to assemble in underground mining sites. Background Technology

[0002] Gold mines refer to gold ore or gold deposits (mountains). Gold ore is a mineral aggregate with sufficient gold content that can be industrially utilized.

[0003] Gold content in gold mines is typically low, requiring extraction from the ore through processes such as beneficiation and smelting. Gold mining is a complex process that demands highly specialized skills.

[0004] When mining gold, sustainable mining methods must be adopted to minimize negative environmental impacts and respect the rights of local communities and workers. Ventilation devices are essential equipment in gold mining, and their main function is to ensure air circulation in the mining area, remove harmful gases and dust, and keep the air fresh, thereby protecting the safety and health of workers. However, conventional ventilation devices are cumbersome to transport due to their large size, and require bolts for assembly, which is also troublesome. Therefore, modifications and optimizations are necessary. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a ventilation device that is easy to assemble in underground mining sites, which has the advantages of easy assembly and anti-clogging.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device for easy assembly in underground mining sites, comprising a base frame and a ventilation duct, wherein the ventilation duct is fixedly installed above the base frame.

[0007] A second air duct is movably installed on one side of the first air duct. Two fixed frames are fixedly installed on the side of the second air duct. A rotating frame is rotatably installed on one side of each fixed frame. A spring is fixedly installed on one side of the rotating frame. A movable plate is fixedly installed on one end of the spring. A fixed rod is fixedly installed on one side of the movable plate. One end of the fixed rod passes through the left and right sides of the first air duct and extends into the interior of the second base frame. A handle is fixedly installed on one side of the movable plate. One end of the handle passes through one side of the rotating frame. A sliding rod is fixedly installed on one side of the rotating frame. The sliding rod is movably connected to the movable plate.

[0008] As a preferred technical solution of this utility model, a driving mechanism is fixedly installed on one side of the air duct, a threaded rod is fixedly installed on one end of the driving mechanism, a threaded block is threadedly sleeved on the outer surface of the threaded rod, an adhesive cylinder is rotatably installed on one side of the threaded block, a limiting rod is fixedly installed on one side of the air duct, a slider is movably sleeved on the outer surface of the limiting rod, and one side of the slider is rotatably connected to the adhesive cylinder.

[0009] As a preferred technical solution of this utility model, the driving mechanism includes a motor fixedly installed on one side of the air duct, a connecting frame fixedly installed above the transmission shaft of the motor, and one side of the connecting frame fixedly connected to a threaded rod.

[0010] As a preferred embodiment of this utility model, a filter screen is fixedly installed on one side of the air duct, and one side of the filter screen is movably connected to the adhesive tube.

[0011] As a preferred embodiment of this utility model, a protective cover is fixedly installed on one side of the air duct, and the protective cover is located outside the motor.

[0016] As a preferred technical solution of this utility model, a motor three is fixedly installed on one side of the support plate two, and a fan blade two is fixedly installed above the transmission shaft of the motor three.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model connects air duct one and air duct two. Moving the handle to the right compresses the spring, causing the moving plate to move to the right on the outer surface of the sliding rod, thereby moving the fixed rod to the right.

[0028] 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.

[0029] like Figures 1 to 7 As shown, this utility model provides a ventilation device that is easy to assemble in underground mining sites, including a base frame 1 and a ventilation duct 2, with the ventilation duct 2 fixedly installed above the base frame 1.

[0030] A second air duct 4 is movably installed on one side of the first air duct 2. Two fixed brackets 5 are fixedly installed on the side of the second air duct 4. A rotating bracket 6 is rotatably installed on one side of each fixed bracket 5. A spring 7 is fixedly installed on one side of the rotating bracket 6. A movable plate 8 is fixedly installed on one end of the spring 7. A fixed rod 9 is fixedly installed on one side of the movable plate 8. One end of the fixed rod 9 passes through the left and right sides of the first air duct 2 and extends into the interior of the second base frame 3. A handle 10 is fixedly installed on one side of the movable plate 8. One end of the handle 10 passes through one side of the rotating bracket 6. A sliding rod 11 is fixedly installed on one side of the rotating bracket 6. The sliding rod 11 is movably connected to the movable plate 8.

[0031] When in use, the operator first connects one end of the air duct 1 (2) and the air duct 2 (4). Then, by moving the handle 10 to the right, the spring 7 is compressed, which in turn moves the moving plate 8 to the right, causing it to move on the outer surface of the slide rod 11. This movement of the moving plate 8 to the right moves the fixing rod 9 to the right. Due to gravity, the rotating frame 6 is then rotated 90 degrees counterclockwise. When the rotating frame 6 reaches 90 degrees, the operator releases the handle 10, and the spring 7 moves the fixing rod 9 into the interior of the air duct 1 (2) and the air duct 2 (4), thus fixing their positions.

[0032] By connecting air duct 1 (2) and air duct 2 (4), moving handle 10 to the right compresses spring 7, causing moving plate 8 to move to the right on the outer surface of slide rod 11, thereby moving fixed rod 9 to the right. After rotating rotating frame 6 counterclockwise by 90 degrees, handle 10 is released, and spring 7, along with fixed rod 9, enters the interior of air duct 1 (2) and air duct 2 (3), fixing the positions of air duct 1 (2) and air duct 2 (4). Compared with traditional devices, this device improves the ease of installation through the rapid assembly of air duct 1 (2) and air duct 2 (4), thereby improving the working efficiency of the device.

[0033] Among them, a drive mechanism is fixedly installed on one side of the air duct 12, a threaded rod 14 is fixedly installed on one end of the drive mechanism, a threaded block 15 is threadedly sleeved on the outer surface of the threaded rod 14, a sticky tube 16 is rotatably installed on one side of the threaded block 15, a limit rod 19 is fixedly installed on one side of the air duct 12, a slider 20 is movably sleeved on the outer surface of the limit rod 19, and one side of the slider 20 is rotatably connected to the sticky tube 16.

[0034] When the operator uses the device, they first start the motor 12 via the controller. When the motor 12 starts, it drives the connecting frame 13 to rotate. When the connecting frame 13 rotates, it drives the threaded rod 14 to rotate. When the threaded rod 14 rotates, since the threaded block 15 and the threaded rod 14 are connected by threads, the threaded block 15 moves as the threaded rod 14 rotates. When the threaded block 15 moves, it drives the sticky cylinder 16 to roll on the surface of the filter screen 18, thereby driving the slider 20 to slide on the surface of the limit rod 19.

[0035] By starting the motor 12, the connecting frame 13 and the threaded rod 14 are driven to rotate. Since the threaded rod 14 is threadedly connected to the threaded block 15, the rotation of the threaded rod 14 drives the movement of the threaded block 15, which in turn causes the sticky cylinder 16 to roll on the surface of the filter screen 18 and drives the slider 20 to slide on the surface of the limiting rod 19. Compared with the traditional device, this device can avoid dust from clogging the surface of the filter screen 18 by cleaning the dust on the surface of the filter screen 18, thereby affecting ventilation and improving the ventilation efficiency.

[0036] The drive mechanism includes a motor 12 fixedly mounted on one side of the air duct 2. A connecting frame 13 is fixedly mounted above the drive shaft of the motor 12, and one side of the connecting frame 13 is fixedly connected to the threaded rod 14.

[0037] By starting the motor 12, the connecting frame 13 is driven to rotate, and the rotation of the connecting frame 13 drives the rotation of the threaded rod 14.

[0038] Among them, a filter screen 18 is fixedly installed on one side of the air duct 12, and one side of the filter screen 18 is movably connected to the adhesive tube 16.

[0039] The design of filter 18 blocks dust, preventing excessive dust from affecting the operation of motor 22 and motor 26.

[0040] Among them, a protective cover 17 is fixedly installed on one side of the air duct 12, and the protective cover 17 is located outside the motor 12.

[0041] The protective cover 17 is designed to connect with the internal ventilation ducts, facilitating ventilation of the mine interior.

[0042] Among them, a gas detector 28 is installed on the side inside the ventilation duct 1 2, and a base frame 2 3 is fixedly installed at the bottom of the ventilation duct 2 4.

[0043] The gas detector 28 is designed to detect gases. When the level of harmful gases exceeds the limit, the controller will activate motor 22 and motor 3 26.

[0044] Among them, a support plate 21 is fixedly installed on the side inside the second ventilation duct 4, and a fixing plate 24 is fixedly installed on one side outside the second ventilation duct 4.

[0045] The design of the support plate 21 and the fixing plate 24 fixes the position of the motor 22, thereby facilitating the operation of the motor 22.

[0046] Among them, a motor 22 is fixedly installed on one side of the support plate 21, and a fan blade 23 is fixedly installed above the drive shaft of the motor 22. The fan blade 23 is rotatably connected to the fixed plate 24.

[0047] The controller starts motor 22, which drives the fan blades 23 to rotate, thereby achieving the ventilation effect.

[0048] Among them, a support plate 25 is fixedly installed on the side inside the air duct 2. The support plate 25 is cross-shaped.

[0049] The design of support plate 25 facilitates the improvement of the stability of motor 3 26 and the stability of motor 3 26 inside the air duct 1 2.

[0050] Among them, a motor 26 is fixedly installed on one side of the support plate 25, and a fan blade 27 is fixedly installed above the drive shaft of the motor 26.

[0051] The controller starts motor 26, which drives the rotation of fan blade 27, thereby coordinating with the rotation of fan blade 23 to achieve better ventilation.

[0052] Working principle and usage process of this utility model:

[0053] When in use, the operator first connects one end of the air duct 1 (2) and the air duct 2 (4). Then, by moving the handle 10 to the right, the spring 7 is compressed, which in turn moves the moving plate 8 to the right, causing it to move on the outer surface of the slide rod 11. This movement of the moving plate 8 to the right moves the fixing rod 9 to the right. Due to gravity, the rotating frame 6 is then rotated 90 degrees counterclockwise. When the rotating frame 6 reaches 90 degrees, the operator releases the handle 10, and the spring 7 moves the fixing rod 9 into the interior of the air duct 1 (2) and the air duct 2 (4), thus fixing their positions.

[0054] When the operator uses the device, they first start the motor 12 via the controller. When the motor 12 starts, it drives the connecting frame 13 to rotate. When the connecting frame 13 rotates, it drives the threaded rod 14 to rotate. When the threaded rod 14 rotates, since the threaded block 15 and the threaded rod 14 are connected by threads, the threaded block 15 moves as the threaded rod 14 rotates. When the threaded block 15 moves, it drives the sticky cylinder 16 to roll on the surface of the filter screen 18, thereby driving the slider 20 to slide on the surface of the limit rod 19.
