Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a homemade fan for use underground. Background Technology

[0002] Fans, as a common electrical appliance, play an important role in life. The working principle of a fan is that the blades are driven by an electric motor to rotate, thereby generating airflow. The air carries away the heat from the surface of the human body, thus achieving a cooling effect. This allows underground workers to stay cool and comfortable, improving their working environment, helping to reduce their stress and occupational diseases, and thus improving their physical and mental health.

[0003] Liuzhuang Coal Mine is a "double outburst mine," meaning it is a mine where both coal and gas outbursts occur. Explosion-proof electrical equipment must be used underground. However, underground signal rooms, substations, pump rooms, and charging rooms are often explosion-proof, poorly ventilated, hot, and humid, and contain hazardous gases such as SO2, H2S, and CO2, which seriously damage the health and lives of miners, corrode equipment, and severely disrupt its normal operation.

[0004] Therefore, this utility model proposes a self-made fan for use underground to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a self-made fan for use underground to solve the problems in the existing technology where underground signal rooms, substations, pump rooms, charging rooms, etc., are explosion-proof, poorly ventilated, hot and humid, and contain harmful gases such as SO2, H2S, and CO2, which seriously damage the health and lives of miners, corrode equipment, and severely disrupt the normal operation of equipment.

[0006] To achieve the purpose of this utility model, the following technical solution is adopted: A homemade fan for use in wells includes an explosion-proof base, a return air sleeve fixedly installed on the top of the explosion-proof base, a connecting plate fixedly installed on the inner side wall of the return air sleeve near the top, a support column passing through the inner side of the connecting plate and fixedly connected thereto, a support seat rotatably connected to the top of the support column, a fan blade rotatably connected to the left side of the support seat near the center, an explosion-proof mesh cover fixedly installed on the left side of the support seat and at the outer edge of the fan blade, a driving assembly provided on the right side of the support seat for driving the fan blade to rotate, and a water filling assembly provided on the right side of the return air sleeve for adding water to the device.

[0007] A further improvement is that: multiple heat dissipation holes are provided on the inner side of the connecting plate and on the outer edge of the support column, and mounting bolts are provided on the front side of the support base.

[0008] A further improvement is that the drive assembly includes a safety cover, the left end of which is fixedly connected to the right side of the support base, a mounting bracket is fixedly installed on the inner side of the safety cover near the center, blades are rotatably connected to the inner side of the mounting bracket, a pneumatic rotor is passed through the inner side of the blades and fixedly connected thereto, the left end of the pneumatic rotor is fixedly connected to the right end of the fan blade, and an air inlet pipe is connected to the rear end of the safety cover and located on the right side of the mounting bracket.

[0009] A further improvement is that a connecting hose is fixedly installed on the front side of the safety cover near the right side, and the end of the connecting hose away from the safety cover is fixedly connected to the front side of the support column. A return air hole communicating with the connecting hose is opened at the center of the inner side of the support column.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown in the figure, this embodiment proposes a solution: a self-made fan for use in wells, including an explosion-proof base 1, a return air sleeve 2 fixedly installed on the top of the explosion-proof base 1, a connecting plate 7 fixedly installed on the inner side wall of the return air sleeve 2 near the top, a support column 3 passing through the inner side of the connecting plate 7 and fixedly connected thereto, a support seat 4 rotatably connected to the top of the support column 3, a fan blade 5 rotatably connected to the left side of the support seat 4 near the center, an explosion-proof mesh cover 6 fixedly installed on the left side of the support seat 4 and located at the outer edge of the fan blade 5, a drive assembly is provided on the right side of the support seat 4 for driving the fan blade 5 to rotate, and a water filling assembly is provided on the right side of the return air sleeve 2 for adding water to the device.

[0021] In this embodiment, during operation, the device connects to an air compressor via a drive component. When the air compressor is started, the high-pressure air, influenced by the high-pressure air, drives the fan blades 5 to rotate and blow forward, achieving a close airflow, circulating air, providing healthy cooling, refreshing comfort, safety against explosions, dust and moisture, and strong air delivery. Simultaneously, a portion of the high-pressure air is transported to the inside of the return air sleeve 2 via the support column 3. Water is added to the inside of the return air sleeve 2 through the water filling component box, ensuring the water covers the lower end of the support column 3. This reduces wind noise generated during operation. At the same time, the rotation of the fan blades 5 reduces the pressure at the top of the return air sleeve 2, thereby driving the water-moistened air inside the return air sleeve 2 forward, increasing air humidity and further enhancing the cooling effect.

[0022] Multiple heat dissipation holes are provided on the inner side of the connecting plate 7 and on the outer edge of the support column 3. Mounting bolts are provided on the front side of the support base 4. The mounting bolts make it easy for the staff to manually adjust the support base 4 up and down to a suitable angle to expand the air blowing area.

[0023] The drive assembly includes a safety cover 8, the left end of which is fixedly connected to the right side of the support base 4. A mounting bracket is fixedly installed near the center of the inner side of the safety cover 8. A blade 9 is rotatably connected to the inner side of the mounting bracket. A pneumatic rotor 10 is inserted through the inner side of the blade 9 and fixedly connected to it. The left end of the pneumatic rotor 10 is fixedly connected to the right end of the fan blade 5. An air inlet pipe 11 is connected to the rear end of the safety cover 8 and located on the right side of the mounting bracket. The air inlet pipe 11 is connected to the underground compressed air system, which delivers compressed air to the inner side of the safety cover 8. The compressed air impacts the blade 9 rotatably connected to the inner side of the mounting bracket, causing the blade 9 to rotate at high speed. When the blade 9 rotates, it drives the pneumatic rotor 10 fixedly connected to it to rotate synchronously. The left end of the pneumatic rotor 10 is fixedly connected to the right end of the fan blade 5, thereby driving the fan blade 5 to rotate and generate airflow. The pneumatic drive method eliminates the need for electrical components, completely avoiding the generation of electrical sparks and meeting the underground explosion-proof requirements.

[0024] A connecting hose 12 is fixedly installed on the front side of the safety cover 8 near the right side. The end of the connecting hose 12 away from the safety cover 8 is fixedly connected to the front side of the support column 3. A return air hole is opened at the center of the inner side of the support column 3, which is connected to the connecting hose 12. A portion of the high-pressure air is delivered to the inside of the return air sleeve 2 through the connecting hose 12 and the return air hole. Water is added to the inside of the return air sleeve 2 through the water filling component box so that the water covers the lower end of the support column 3. This can reduce the wind noise generated during operation.

[0025] The water filling assembly includes a water tank 13. The left side of the water tank 13 is fixedly connected to the right side of the return air sleeve 2. A delivery pipe 14 is fixedly installed at the center of the bottom of the water tank 13. A sealing ring 15 is fixedly installed on the inner wall of the delivery pipe 14 near the top. A drain hole is opened at the center of the inner side of the sealing ring 15. A support frame is fixedly installed on the inner wall of the delivery pipe 14 at the bottom of the sealing ring 15. A lifting rod 16 adapted to the drain hole is inserted through the center of the inner side of the support frame and slidably connected to it. A hollow ball 17 is fixedly installed at the bottom end of the lifting rod 16. The clean water stored in the water tank 13 flows to the bottom delivery pipe 14 under the action of gravity, connects to the pipe 19 and enters the inside of the return air sleeve 2. As the water level rises, the hollow ball 17 floats upward under the action of buoyancy, which drives the lifting rod 16 to rise. When the top of the lifting rod 16 is in contact with the drain hole of the sealing ring 15, the water flow stops. When the water level in the return air sleeve 2 drops after being consumed, the water level at the bottom of the delivery pipe 14 drops, the gravity of the hollow ball 17 is greater than the buoyancy, the lifting rod 16 drops, and the drain hole opens again to realize automatic water replenishment.

[0026] A water inlet pipe 18 is fixedly installed on the top of the water tank 13, and a connecting pipe 19 is fixedly installed at the bottom of the delivery pipe 14. The end of the connecting pipe 19 away from the delivery pipe 14 passes through the side wall of the return air sleeve 2 and is fixedly connected to it. A rubber ring 20 is fixedly installed on the surface of the lifting rod 16 near the top to enhance the sealing between the lifting rod 16 and the drain hole of the sealing ring 15 and prevent water leakage.

[0027] The above embodiment discloses a homemade fan for use underground. The air inlet pipe 11 is connected to the underground compressed air system, delivering compressed air to the inside of the safety cover 8. This compressed air impacts the blades 9, which are rotatably connected to the inner side of the mounting frame, causing the blades 9 to rotate at high speed. The rotation of the blades 9 drives the pneumatic rotor 10, which is fixedly connected to them, to rotate synchronously. The left end of the pneumatic rotor 10 is fixedly connected to the right end of the fan blades 5, thereby driving the fan blades 5 to rotate and generate airflow. This pneumatic drive eliminates the need for electrical components, completely avoiding electrical sparks and meeting underground explosion-proof requirements. A portion of the high-pressure air is delivered to the inside of the return air sleeve 2 through the connecting hose 12 and the return air hole, and then returns through the water filling assembly box to the return air sleeve. Water is added to the inside of the support column 3 until it is submerged. This reduces wind noise during operation. The clean water stored in the water tank 13 flows to the bottom conveying pipe 14 and connecting pipe 19 under gravity and enters the inside of the return air sleeve 2. As the water level rises, the hollow ball 17 floats upward under the action of buoyancy, which drives the lifting rod 16 to rise. When the top of the lifting rod 16 is in contact with the drain hole of the sealing ring 15, the water flow stops. When the water level in the return air sleeve 2 drops after being consumed, the water level at the bottom of the conveying pipe 14 drops. The weight of the hollow ball 17 is greater than the buoyancy, the lifting rod 16 drops, and the drain hole opens again, realizing automatic water replenishment and reducing the risk of heatstroke caused by the hot environment for miners.
