Description

Technical Field

[0001] The invention relates to the technical field of mine ventilation devices, in particular to a single-channel air supply type mine ventilation device. Background Art

[0002] Single-channel air supply type mine ventilation device is a device used for underground ventilation in mines, which is designed to ensure the freshness and safety of the air inside the mine, help to remove harmful gases, control temperature and improve the comfort of the working environment. Single-channel air supply type ventilation system is a common form of mine ventilation, which mainly introduces fresh air into the mine through a main air supply channel, and distributes and flows air through other channels in the mine. Mine ventilation refers to the establishment of an effective ventilation system during the mining process to ensure air circulation in the mine to maintain a good working environment. Ventilation not only contributes to the health and safety of miners, but also helps to improve production efficiency.

[0003] Existing ventilation devices, such as air supply ventilation devices, need to draw air from the outside into the mine when ventilating the mine. However, when drawing air, dust and lint from the outside will enter the ventilation device and block the ventilation area. Dust accumulates in the vents and pipes, which will increase the resistance to airflow, thereby reducing the ventilation effect and making it difficult to maintain the designed air flow. Long-term dust accumulation may cause wear on the blower and other ventilation equipment, reducing the service life and efficiency of the equipment. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a single-channel air supply type mine ventilation device, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a single-channel air supply type mine ventilation device, comprising a ventilation pipe, one side of the ventilation pipe is fixedly connected to an air pump, one end of the air pump is fixedly connected to an air supply pipe, the outer surface of the air supply pipe is fixedly connected to a connecting pipe, the outer surface of the connecting pipe is provided with an air outlet groove, one end of the connecting pipe is fixedly connected to a cleaning mechanism, and the outer surface of the ventilation pipe is provided with an A groove for fixedly installing an A sound insulation board;

[0006] The cleaning mechanism comprises a fan blade, one end of which is fixedly connected to one end of a connecting pipe, the other end of which is fixedly connected to a connecting rod, and one end of which is fixedly connected to a brush head.

[0007] A further improvement of the technical solution of the present invention is that a B groove is opened inside the ventilation pipe, and a B sound insulation board is fixedly connected to the inside of the B groove.

[0008] A further improvement of the technical solution of the present invention is that a C-groove for fixing a ventilation plate is provided on the other side of the ventilation pipe, and a ventilation groove is provided on the surface of the ventilation plate.

[0009] A further improvement of the technical solution of the present invention is that auxiliary rods are fixedly connected to both sides of the outer surface of the ventilation pipe, and a sleeve rod is sleeved on the outer surface of the auxiliary rod.

[0010] A further improvement of the technical solution of the present invention is that: the outer surface of the sleeve rod is provided with an A threaded hole for threading a fixing bolt, and the outer surface of the auxiliary rod is provided with a B threaded hole adapted to the fixing bolt.

[0011] A further improvement of the technical solution of the present invention is that: a support plate is hinged at the bottom of the sleeve rod through an angle steel, a universal wheel is fixedly connected to the bottom of the support plate, and a brake pad is rotatably connected inside the universal wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the cleaning mechanism, the air supply ventilation device needs to draw air from the outside to enter the mine when ventilating the mine. However, when drawing air, dust and cotton wool from the outside will enter the ventilation device and block the ventilation area. The cleaning mechanism is used to remove the dust at the vent when supplying air. Removing dust can reduce the concentration of suspended particles in the air, improve the air quality in the mine, and reduce the risk of respiratory diseases and other health problems for workers. Dust on the surface of the vent will increase the resistance of the airflow. Regular cleaning can maintain good airflow, ensure that the ventilation system can work normally, and maintain the required air supply volume;

[0014] 2. Through the installation of A sound insulation board, the echo in the mine is usually large. If the sound of the ventilation device is increased, the sound in the mine will be louder, resulting in excessive noise, affecting the work of the staff in the mine. The use of A sound insulation board can reduce the noise when the ventilation device is working. The high noise environment of the mine will affect the hearing and concentration of the workers. Effective noise reduction measures can create a quieter working environment and improve work comfort. By controlling noise, the vibration of the equipment can often be effectively controlled, reducing equipment damage and failure rate caused by vibration, thereby extending the service life of the equipment.

[0021] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0022] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0023] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0024] Reference Figure 1-Figure 5 , the present invention provides two technical solutions:

[0025] Embodiment 1:

[0026] A single-channel air supply type mine ventilation device comprises a ventilation pipe 1, one side of the ventilation pipe 1 is fixedly connected to an air pump 2, one end of the air pump 2 is fixedly connected to an air supply pipe 3, the outer surface of the air supply pipe 3 is fixedly connected to a connecting pipe 4, the outer surface of the connecting pipe 4 is provided with an air outlet groove, one end of the connecting pipe 4 is fixedly connected to a cleaning mechanism, and the outer surface of the ventilation pipe 1 is provided with an A groove for fixedly installing an A sound insulation board 5;

[0027] The cleaning mechanism comprises a fan blade 6 , one end of which is fixedly connected to one end of the connecting tube 4 , the other end of which is fixedly connected to a connecting rod 7 , and one end of which is fixedly connected to a brush head 8 .

[0028] When the air supply ventilation device is ventilating the mine, it is necessary to draw air from the outside into the mine. However, when drawing air, dust and lint from the outside will enter the ventilation device and block the ventilation. The dust at the vents is removed by a cleaning mechanism when the air is supplied. Dust removal can reduce the concentration of suspended particles in the air, improve the air quality in the mine, and reduce the risk of respiratory diseases and other health problems for workers. Dust on the surface of the vents will increase the resistance of the airflow. Regular cleaning can maintain good airflow, ensure that the ventilation system can work normally, and maintain the required air supply.

[0029] Embodiment 2:

[0030] On the basis of Example 1: a B groove is opened inside the ventilation pipe 1, and a B sound insulation board 9 is fixedly connected to the inside of the B groove. The B sound insulation board 9 can reduce the noise of the ventilation device when it is working. The high noise environment of the mine will affect the hearing and concentration of the workers. Effective noise reduction measures can create a quieter working environment and improve work comfort. By controlling noise, the vibration of the equipment can often be effectively controlled, reducing equipment damage and failure rate caused by vibration, thereby extending the service life of the equipment.

[0031] A C-groove for fixing the ventilation plate 10 is provided on the other side of the ventilation pipe 1, and ventilation grooves are provided on the surface of the ventilation plate 10. The ventilation grooves on the surface of the ventilation plate 10 play a ventilation role, so that the wind inside the ventilation pipe 1 is smoothly transmitted to the mine.

[0032] Auxiliary rods 11 are fixedly connected to both sides of the outer surface of the ventilation pipe 1, and a sleeve rod 12 is sleeved on the outer surface of the auxiliary rod 11. The height of the auxiliary rod 11 in the sleeve rod 12 is adjusted according to the height of the mine entrance. After adjusting to a suitable height, it is reinforced with a fixing bolt 13.

[0033] The outer surface of the sleeve rod 12 is provided with a threaded hole A for screwing a fixing bolt 13, and the outer surface of the auxiliary rod 11 is provided with a threaded hole B adapted to the fixing bolt 13. The fixing bolt 13 plays a reinforcing role, fixing the auxiliary rod 11 and the sleeve rod 12 to prevent the auxiliary rod 11 from falling.

[0034] The bottom of the sleeve rod 12 is hinged with a support plate 14 through an angle steel, and the bottom of the support plate 14 is fixedly connected with a universal wheel 15, and the internal rotation of the universal wheel 15 is connected with a brake pad. The universal wheel 15 can evenly distribute the load, making it easier to move and turn, reducing the burden on the transporter or operator.

[0035] On the basis of Embodiment 1 and Embodiment 2: When ventilating the interior of a mine, the ventilation device is moved to the mine entrance using the universal wheel 15 and the support plate 14. The height of the auxiliary rod 11 in the sleeve rod 12 is adjusted according to the height of the mine entrance. After adjusting to a suitable height, it is reinforced using the fixing bolt 13. Subsequently, the vacuum pump 2 is started. The vacuum pump 2 draws air from the outside, and the drawn air is sent into the connecting pipe 4 using the air supply pipe 3. The wind is dispersed from the air outlet groove on the outer surface of the connecting pipe 4. After being dispersed, the wind flows in the ventilation pipe 1. When the wind passes through the fan blades 6, it drives the fan blades 6 to rotate. The fan blades 6 increase the wind speed and transmit the wind from the ventilation plate 10 to the mine. Subsequently, when ventilating the mine, it is necessary to draw air from the outside into the mine, but when the air is drawn, there will be dust and cotton wool on the outside. When dust enters the ventilation device, it will block the ventilation area. Dust accumulates in the vents and pipes, which will increase the resistance to airflow, thereby reducing the ventilation effect and making it difficult to maintain the designed air flow. When the fan blades 6 rotate, the connecting rod 7 and the brush head 8 are driven to rotate. The brush head 8 cleans the dust on the surface of the ventilation plate 10 to prevent dust from accumulating on the surface of the ventilation plate 10 and affecting the ventilation effect. Subsequently, when the ventilation device is working, the B sound insulation board 9 inside the ventilation duct 1 and the A sound insulation board 5 outside the ventilation duct 1 are used to achieve the effect of noise reduction. Effective noise reduction measures can create a quieter working environment and improve working comfort. By controlling noise, the vibration of the equipment can often be effectively controlled, reducing equipment damage and failure rate caused by vibration, thereby extending the service life of the equipment.
