Description

Technical Field

[0001] The present invention relates to the technical field of mine cooling, and particularly relates to a mine local cooling spray device. Background Art

[0002] In mine exploitation operations, the underground environment is complex and changeable, and the high-temperature problem seriously affects the working efficiency and physical health of miners. With the increase in mining depth and the improvement of mechanization level, the heat sources in the mine increase, and the temperature in local areas often remains high. Therefore, efficient local cooling measures have become the key to ensuring the safe production of mines and improving the comfort of the working environment.

[0003] Currently, most mine local cooling uses traditional spray devices. These devices have exposed many problems in practical applications. On the one hand, the power transmission and spraying mechanism of traditional spray devices are relatively simple, mostly in the form of linear spraying or fixed-angle spraying. This single spraying mode results in a limited water mist coverage area, making it difficult to comprehensively and evenly contact the hot air in various areas of the mine. As a result, in areas with poor air circulation, such as roadway corners and equipment-intensive areas, local overheating is likely to occur, and in areas with good air circulation, the ideal cooling effect may not be achieved due to uneven spraying. This not only reduces the cooling efficiency but also makes the temperature difference in the mine working environment relatively large, unable to provide a comfortable and suitable working environment for miners.

[0004] On the other hand, the traditional devices lack effective optimization design in water flow distribution. The water flow often cannot be evenly distributed within the spraying area, resulting in excessive water volume in some areas, causing water resource waste, while insufficient water volume in some areas leads to poor cooling effect. This uneven water flow distribution further exacerbates the unevenness of cooling and cannot meet the diverse cooling requirements of different areas in the mine. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mine local cooling spray device, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] A mine local cooling spray device includes a mounting plate. An installation box is slidably installed inside the mounting plate. A connecting block is fixedly installed on the side wall of the installation box. A swinging mechanism is fixedly installed at the bottom of the connecting block. The swinging mechanism includes a servo motor. The servo motor is fixedly installed at the bottom of the connecting block. A missing gear is fixedly installed on the side wall of the output shaft of the servo motor. A first gear is rotatably installed on the side wall of the installation box. A torsion spring is sleeved on the side wall of the first gear. A second synchronous belt drive assembly is drivingly installed on the side wall of the output shaft of the servo motor. A spiral body is drivingly installed inside the second synchronous belt drive assembly. A transmission cylinder is rotatably installed at the bottom of the installation box. A first synchronous belt drive assembly is drivingly installed on the side wall of the first gear. An atomizing nozzle is fixedly installed on the side wall of the transmission cylinder.

[0008] In a possible implementation manner, the output shaft of the servo motor is rotatably installed on the side wall of the installation box, and the first gear is meshingly installed with the missing gear.

[0009] In a possible implementation manner, one end of the torsion spring away from the first gear is fixedly installed with the installation box, and the transmission cylinder is drivingly installed inside the first synchronous belt drive assembly.

[0010] In a possible implementation manner, the spiral body is rotatably installed inside the transmission cylinder, and a cylinder is fixedly installed on the top of the mounting plate.

[0011] In a possible implementation manner, a pneumatic push rod is fixedly installed at the output end of the cylinder, and a connecting box is fixedly installed at the end of the pneumatic push rod away from the cylinder.

[0012] In a possible implementation manner, the bottom of the connecting box is fixedly installed with the installation box, a telescopic pipe is fixedly installed on the side wall of the connecting box, and a rotating cylinder is fixedly installed at the bottom of the telescopic pipe.

[0013] In a possible implementation manner, a chuck is rotatably installed on the side wall of the rotating cylinder, and a connecting pipe is inserted and installed inside the telescopic pipe.

[0014] In a possible implementation manner, a sealing disk is sleeved on the side wall of the connecting pipe, and a spring is fixedly installed at the bottom of the sealing disk.

[0015] In a possible implementation manner, the spring is sleeved on the side wall of the connecting pipe, and a cross connecting disk is fixedly installed on the side wall of the connecting pipe.

[0016] In a possible implementation manner, the top of the cross connecting disk is fixedly installed with the spring, a mounting frame is fixedly installed at the bottom of the mounting plate, and a sliding wheel assembly is fixedly installed at the bottom of the mounting frame.

[0017] Beneficial effects compared with the prior art:

[0018] 1. In this solution, the servo motor drives the missing gear to rotate. With a unique meshing method with the first gear and the energy storage and release of the torsion spring, the first gear rotates alternately in the forward and reverse directions. Through the first synchronous belt drive assembly, it is converted into the left and right swing of the transmission cylinder. At the same time, the servo motor also drives the spiral body to rotate in the transmission cylinder through the second synchronous belt drive assembly, quickly and evenly distributing the water flow. So that during the left and right swing of the atomizing nozzle, the water can be evenly atomized and sprayed out, achieving large-area and uniform cooling. In different areas of the mine, whether the air circulation is good or bad, the uniformity of cooling can be ensured. Compared with the traditional simple linear spraying or fixed-angle spraying method, through a unique power transmission and spraying mechanism, the water mist can fully contact the hot air, greatly improving the cooling efficiency, creating a more comfortable and temperature-appropriate working environment for the mine workers, and effectively avoiding the problems of local overheating or uneven cooling;

[0019] 2. In this solution, when the connecting pipe needs to be replaced due to conditions such as wear and blockage after long-term use, the staff only needs to rotate the rotating cylinder at the bottom of the telescopic pipe counterclockwise. The rotating cylinder drives the chuck to rotate synchronously. When the slot of the chuck coincides with the cross-connecting disc fixed on the side wall of the connecting pipe, the compressed spring instantly releases its elastic force and easily pushes the connecting pipe out of the current position. The sealing disc also immediately detaches from the bottom of the telescopic pipe. The entire disassembly process is simple and fast. This design avoids the situation where various complex tools may be needed and a large amount of time and energy may be consumed during the replacement of the traditional connecting pipe. It not only significantly reduces the maintenance difficulty, enabling non-professional maintenance personnel to quickly get started, but also greatly reduces the downtime of the equipment due to maintenance, reduces the maintenance cost, and improves the overall operation efficiency and service life of the equipment;

[0020] 3. In this solution, to further improve the cooling effect, the device is equipped with a spray area expansion structure composed of a cylinder, a pneumatic push rod, a connecting box, etc. After starting the cylinder, the pneumatic push rod at its output end expands and contracts regularly, pushing the connecting box to move back and forth. On the one hand, the connecting box drives the telescopic pipe to adaptively extend and contract to ensure that the water flow transmission is not affected; on the other hand, it drives the connected installation box to move synchronously. Combined with the left and right swing of the transmission cylinder itself, a larger spray coverage area is formed in a local area of the mine. In the case of a complex spatial layout in the mine, whether it is a wide mining site or a narrow passage connection, the device can effectively expand the cooling range through this combined movement of back and forth, left and right, ensuring that every corner can be fully cooled, greatly enhancing the applicability of the device in different mine environments. Compared with traditional fixed-range spray equipment, it can more comprehensively meet the diverse cooling needs in the mine. Brief Description of the Drawings

Specific embodiments

[0029] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. In addition, in order to describe the present invention more clearly, components not connected to the invention will be omitted from the drawings;

[0030] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology. The general idea is as follows:

[0031] Embodiment:

[0032] Please refer to Figures 1 to 6 As shown, this embodiment introduces the specific structure of a mine local cooling spray device, including a mounting plate 11. When in use, push the mounting frame 34, and the mounting frame 34 will drive the sliding wheel assembly 35 to move. The sliding wheel assembly 35 will reduce the friction between the device and the ground, making it easier to push the device.

[0033] An installation box 12 is slidably installed inside the installation plate 11. When the device is pushed to the designated location, the servo motor 14 is started, and the servo motor 14 drives the missing gear 15 to rotate clockwise, and the missing gear 15 drives the first gear 16 to rotate counterclockwise. At this time, the torsion spring 17 will be subjected to force to produce torsion. When the missing gear 15 is not meshed with the first gear 16, the torsion spring 17 will release the torsion force to make the first gear 16 rotate clockwise. A connecting block 13 is fixedly installed on the side wall of the installation box 12, and a servo motor 14 is fixedly installed on the bottom of the connecting block 13. The missing gear 15 is fixedly installed on the side wall of the output shaft of the servo motor 14. The output shaft of the servo motor 14 is rotatably installed on the side wall of the installation box 12. The first gear 16 is rotatably installed on the side wall of the installation box 12, and the first gear 16 is meshed with the missing gear 15. A torsion spring 17 is sleeved on the side wall of the first gear 16, and the end of the torsion spring 17 away from the first gear 16 is fixedly installed on the installation box 12;

[0034] The first synchronous belt transmission assembly 18 drives the transmission drum 21 to rotate, and the transmission drum 21 will swing left and right at this time. The second synchronous belt transmission assembly 36 is installed on the side wall of the output shaft of the servo motor 14, and the spiral body 19 is installed inside the second synchronous belt transmission assembly 36. The transmission drum 21 is rotatably installed at the bottom of the installation box 12, and the first synchronous belt transmission assembly 18 is installed on the side wall of the first gear 16. The transmission drum 21 is installed inside the first synchronous belt transmission assembly 18, and the spiral body 19 is installed inside the transmission drum 21;

[0035] The connecting pipe 29 is passed with water, and the connecting pipe 29 transmits the water to the inside of the telescopic pipe 26, and the telescopic pipe 26 transmits the water to the inside of the connecting box 25, and the connecting box 25 transmits the water to the inside of the installation box 12, and the installation box 12 transmits the water to the inside of the transmission cylinder 21; the side wall of the transmission cylinder 21 is fixedly installed with an atomizing nozzle 22, and at this time, the servo motor 14 also drives the second synchronous belt transmission component 36 to drive clockwise, and the second synchronous belt transmission component 36 drives the spiral body 19 to rotate clockwise, and the spiral body 19 transmits the water evenly and quickly to the inside of the transmission cylinder 21, and the water inside the transmission cylinder 21 is then sprayed out through the atomizing nozzle 22, so as to achieve left and right swinging and uniform spraying, and the top of the mounting plate 11 is fixedly installed with a cylinder 23, and then the cylinder 23 is started, and the cylinder 23 drives the pneumatic push rod 24 to continuously extend and retract;

[0036] A pneumatic push rod 24 is fixedly installed at the output end of the cylinder 23, and a connecting box 25 is fixedly installed at one end of the pneumatic push rod 24 away from the cylinder 23. The pneumatic push rod 24 will push the connecting box 25 to reciprocate back and forth, and the connecting box 25 will drive the telescopic tube 26 to continuously extend and retract, and the connecting box 25 will also drive the installation box 12 to continuously reciprocate back and forth, thereby increasing the cooling spray area;

[0037] The bottom of the connection box 25 is fixedly installed with the installation box 12. A telescopic pipe 26 is fixedly installed on the side wall of the connection box 25. The bottom of the telescopic pipe 26 is fixedly installed with a rotating cylinder 27. A chuck 28 is rotatably installed on the side wall of the rotating cylinder 27. A connecting pipe 29 is inserted and installed inside the telescopic pipe 26. A sealing disc 31 is sleeved on the side wall of the connecting pipe 29. A spring 32 is fixedly installed at the bottom of the sealing disc 31. The spring 32 is sleeved on the side wall of the connecting pipe 29. A cross connecting disc 33 is fixedly installed on the side wall of the connecting pipe 29. The top of the cross connecting disc 33 is fixedly installed with the spring 32. When the connecting pipe 29 needs to be replaced, rotate the rotating cylinder 27 counterclockwise. The rotating cylinder 27 drives the chuck 28 to rotate counterclockwise. When the slot of the chuck 28 coincides with the cross connecting disc 33, the spring 32 will release its elastic force and push the connecting pipe 29 out of the inside of the first gear 16. The sealing disc 31 will also disengage from the bottom of the telescopic pipe 26 to complete the disassembly. A mounting bracket 34 is fixedly installed at the bottom of the mounting plate 11. A sliding wheel assembly 35 is fixedly installed at the bottom of the mounting bracket 34.

[0038] Working principle: In the mine operation scenario, when it is necessary to cool a specific area, the staff moves the entire spraying device by pushing the mounting bracket 34. The sliding wheel assembly 35 installed at the bottom of the mounting bracket 34 plays a key role. Its rolling friction characteristic can greatly reduce the frictional force compared with the sliding friction when the device directly contacts the ground. This enables the staff to significantly reduce the force required when pushing the device, making the operation easier and more convenient. The device can be quickly and labor-savingly transported to the designated location in the mine that needs to be cooled to prepare for the subsequent cooling work.

[0039] When the device reaches the designated position, turn on the servo motor 14 installed at the bottom of the connecting block 13. The servo motor 14 serves as the power source, and its output shaft drives the missing gear 15 to rotate in the clockwise direction. The missing gear 15 has a special structure with partial teeth. When it meshes with the first gear 16, relying on the interaction force between the teeth of the gears, it drives the first gear 16 to rotate counterclockwise. During this process, the torsion spring 17 sleeved on the side wall of the first gear 16 undergoes torsional deformation due to the rotation of the first gear 16, storing elastic potential energy. As the missing gear 15 continues to rotate, when the toothless part of the missing gear 15 rotates to face the first gear 16, the two disengage. At this time, since the torsion spring 17 is no longer subjected to an external force to maintain its deformation, it begins to release the previously stored elastic potential energy, generating a restoring force that causes the first gear 16 to rotate clockwise. The first gear 16 is connected to the transmission cylinder 21 through the first synchronous belt drive assembly 18. The synchronous belt drive assembly relies on the friction between the belt and the pulley to transmit power, and has advantages such as smooth transmission and low noise. The forward and reverse alternating rotation of the first gear 16 is converted into the left and right swinging motion of the transmission cylinder 21 through the first synchronous belt drive assembly 18. This unique power transmission method enables the transmission cylinder 21 to swing left and right regularly within a certain angle range, providing a motion basis for subsequent uniform spraying. At the same time as starting the servo motor 14, connect the connecting pipe 29 to the water supply system in the mine to connect it to the water source. Under the action of water pressure, water first flows into the inside of the telescopic pipe 26. The telescopic pipe 26 has the characteristic of being telescopic and can adapt to the distance change generated during the reciprocating motion of the connecting box 25 back and forth to ensure unobstructed water flow. After the water flows out of the telescopic pipe 26, it enters the connecting box 25. The connecting box 25 plays a role of transition and distribution, guiding the water into the installation box 12. The installation box 12 serves as a temporary storage and transfer space for water, providing a channel for the water to further flow to the transmission cylinder 21. At the same time, in addition to driving the missing gear 15 to rotate, the output shaft of the servo motor 14 is also connected to the spiral body 19 through the second synchronous belt drive assembly 36. The second synchronous belt drive assembly 36 also uses friction to achieve power transmission, stably transmitting the rotational power of the servo motor 14 to the spiral body 19, causing it to rotate clockwise. The spiral body 19 is located inside the transmission cylinder 21, and its special spiral structure can exert an axial thrust on the water entering the transmission cylinder 21 during rotation. This thrust causes the water to flow along the spiral path of the spiral body 19 inside the transmission cylinder 21, thereby realizing the uniform and rapid distribution of water inside the transmission cylinder 21, ensuring that sufficient water supply is obtained at each position of the transmission cylinder 21 and providing a guarantee for the uniform spraying of the atomizing nozzle 22;

[0040] The atomizing nozzle 22 fixedly installed on the side wall of the transmission cylinder 21 is a key component for realizing the cooling function. The atomizing nozzle 22 utilizes a special internal structure to break the water into tiny water droplets when water passes through it, forming an atomizing effect. When the water evenly distributed by the spiral body 19 in the transmission cylinder 21 reaches the atomizing nozzle 22, the atomizing nozzle 22 converts the water into fine water mist particles and sprays them out. Since the transmission cylinder 21 swings left and right under the action of the power transmission system, the water mist sprayed by the atomizing nozzle 22 can swing left and right within a certain range, covering a wider area. This left-right swinging and uniform spraying method can enable the water mist to come into contact with the hot air in the mine more comprehensively. Through the principle of heat absorption by water evaporation, it can effectively reduce the air temperature in a local area and create a more comfortable working environment for the mine workers;

[0041] After realizing the basic left-right swinging spray cooling, in order to further increase the coverage area of the cooling spray, the cylinder 23 installed on the top of the mounting plate 11 is started. The cylinder 23 uses compressed air as the power source, and its pneumatic push rod 24 at the output end performs regular telescopic movements under the action of compressed air. The front end of the pneumatic push rod 24 is fixedly connected to the connection box 25. When the pneumatic push rod 24 extends, it applies a forward thrust to the connection box 25, causing the connection box 25 to move forward; when the pneumatic push rod 24 retracts, the connection box 25 moves backward under its pulling force. In this way, the connection box 25 makes reciprocating movements back and forth driven by the pneumatic push rod 24. The forward and backward movements of the connection box 25, on the one hand, drive the telescopic pipe 26 connected to it to continuously extend and contract to adapt to the change in the position of the connection box 25 and ensure the unimpeded water transmission; on the other hand, the connection box 25 is fixedly connected to the installation box 12, so the movement of the connection box 25 also drives the installation box 12 to make reciprocating movements back and forth. The forward and backward movement of the installation box 12 causes the entire spray system to generate displacement changes in the front and back directions. Combined with the left-right swing of the transmission cylinder 21, a larger spray coverage area is formed in a local area of the mine, further improving the cooling effect;

[0042] With the long-term use of the device, the connecting tube 29 may need to be replaced due to wear, blockage and other reasons. When the connecting tube 29 needs to be replaced, the staff rotates the rotating cylinder 27 at the bottom of the telescopic tube 26 counterclockwise. The rotating cylinder 27 is fixedly connected to the chuck 28. The rotation of the rotating cylinder 27 drives the chuck 28 to rotate counterclockwise. The chuck 28 has a specific slotted structure, and a cross connecting disk 33 is fixed to the side wall of the connecting tube 29. When the chuck 28 is rotated until its slot coincides with the cross connecting disk 33, the spring 32 originally in a compressed state obtains a release space. One end of the spring 32 is fixed to the bottom of the sealing disk 31, and the other end is connected to the top of the cross connecting disk 33. The spring 32 is sleeved on the side wall of the connecting tube 29. Under the action of the elastic potential energy of the spring 32, an upward thrust is generated to push the connecting tube 29 out of the current installation position. At the same time, the sealing disk 31 also detaches from the bottom of the telescopic tube 26 as the connecting tube 29 moves. At this point, the disassembly process of the connecting tube 29 is completed, which is convenient for the staff to replace or repair it.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
