Description

Technical Field

[0001] This invention relates to the field of coal mine equipment technology, and specifically to a cooling device and method for coal mine electromechanical equipment. Background Technology

[0002] In modern coal mine production, the widespread application of electromechanical equipment has greatly improved production efficiency and safety. However, these devices generate a large amount of heat during long-term operation, especially under high loads, where temperature rise is particularly pronounced. Excessive temperatures not only affect equipment performance and efficiency but can also lead to equipment malfunctions, accelerate mechanical wear, and even cause safety accidents. Therefore, cooling technology for coal mine electromechanical equipment is particularly important. The main purpose of cooling devices is to effectively control the temperature of the equipment during operation to ensure it operates under optimal conditions. Common cooling methods include air cooling, liquid cooling, and oil cooling. Air cooling systems remove heat through fans or natural ventilation and are suitable for equipment with low heat dissipation requirements. Liquid cooling systems utilize coolant (such as water or special coolants) flowing across the equipment surface for heat exchange and are suitable for high-power, high-heat-load equipment. Oil cooling systems are typically used in power transmission devices, absorbing and removing heat through circulating oil to ensure stable equipment operation. In the coal mining industry, due to the complex environment and harsh conditions, the design and selection of cooling devices must consider a variety of factors. For example, the operating temperature, humidity, and dust concentration of the equipment all affect the cooling effect. Furthermore, the maintenance and upkeep of the cooling devices are crucial; regular inspection and cleaning can effectively extend their service life and improve cooling efficiency. In conclusion, cooling devices for coal mine electromechanical equipment play a crucial role in ensuring equipment safety, extending service life, and improving work efficiency. With the continuous advancement of technology in the coal mining industry, the research and application of cooling devices will continue to deepen, providing a solid technical guarantee for safe coal mine production.

[0003] Patent application number CN202110208149.9 discloses a cooling device for coal mine electromechanical equipment, belonging to the field of coal mine electromechanical equipment cooling technology. This cooling device for coal mine electromechanical equipment includes a vertically arranged shell. The upper end of the shell has an opening for installing the coal mine electromechanical equipment. The upper part of the shell has an upper chamber communicating with the opening, and the lower part of the shell has a lower chamber. The upper part of the outer wall of the shell has a slot communicating with the upper chamber. The lower chamber has a suction component for absorbing cold air, which is detachably connected to the top wall of the lower chamber via a connecting assembly. The lower part of the outer wall of the lower chamber has a suction port. The lower chamber is connected to the slot via a vent pipe. Beneficial effects: Low-temperature cold air is drawn into the shell through the suction component, dissipating heat from the coal mine electromechanical equipment inside the shell. The connecting assembly facilitates the installation and maintenance of the equipment.

[0004] The patent and existing technologies have the following technical problems in practical use: When cooling down coal mine machinery and equipment, the most common method is to blow cooling air into the equipment to cool it down. However, during use, coal mine machinery and equipment often accumulates a lot of dust, debris, and other impurities inside and on its surface. If the air is blown directly into the equipment, the dust will block the air ducts or radiators, thus reducing the cooling effect. In addition, the dust may also enter the interior of the machinery and equipment, causing some damage. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling device and method for coal mine electromechanical equipment in order to solve the above problems.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A cooling device and method for coal mine electromechanical equipment includes a cooling chamber and a cooling cylinder. The cooling cylinder is equipped with a cleaning component, which consists of a cleaning mechanism and a sealing mechanism. The cleaning mechanism includes a cleaning box inside the cooling cylinder, a filter plate inside the cleaning box that can deform to a certain extent, a separation groove on the surface of the cleaning box below the filter plate, a conical cylinder below the cleaning box, a spiral air duct inside the conical cylinder, a pulverizing rod fixedly installed inside the conical cylinder, an air inlet pipe and an air outlet pipe fixedly connected to one side of the cleaning box and the conical cylinder respectively, two sets of cleaning components symmetrically arranged, capable of performing air intake and air blowing operations on the cooling chamber, and the cleaning components can rotate inside the cooling cylinder; The sealing mechanism includes a rubber plate disposed inside the cleaning box, located below the filter plate. The rubber plate is movable inside the cleaning box and seals the separation groove.

[0007] Furthermore, the cleaning box has a movable component inside, a rotating component is fixedly installed on one side of the movable component, a first connecting rod is fixedly installed on one side of the rotating component, an installation ring is fixedly installed inside the cleaning box, a second connecting rod is fixedly installed on the inner wall of the installation ring, and at least six sets of rotating components and second connecting rods are arranged in a ring, with the first connecting rod penetrating and extending into the interior of the second connecting rod.

[0008] Furthermore, the filter plate is arranged in a ring with at least six sets, and is fixedly connected to the first connecting rod and the second connecting rod.

[0009] Furthermore, a transmission tube is provided inside the cleaning box, which extends through and to the bottom of the cleaning box, and an elastic ring is provided inside the cleaning box, which fits against the inner wall of the cleaning box.

[0010] Furthermore, a first sliding rod is fixedly installed on the surface of the transmission tube, and a second sliding rod is fixedly installed on the inner wall of the elastic ring. The first sliding rod passes through and extends into the interior of the second sliding rod. A connecting spring is fixedly installed between the inner walls of the first sliding rod and the second sliding rod. At least six sets of the first sliding rod and the second sliding rod are arranged in a ring.

[0011] Furthermore, a first connecting pipe and a second connecting pipe are respectively provided on one side of the air inlet pipe and the air outlet pipe, and an electric telescopic pipe is fixedly installed on the opposite side of the first connecting pipe and the second connecting pipe.

[0012] Furthermore, a bidirectional fan is fixedly installed on the surface of the cooling cylinder, and the first connecting pipe and the second connecting pipe are fixedly connected to the bidirectional fan.

[0013] Furthermore, a rotating ring is provided inside the cooling cylinder, and the rotating ring is fixedly connected to the surface of the cleaning box. A drive motor is fixedly installed on one side of the cooling cylinder, and a drive rod is fixedly installed at the output end of the drive motor. The drive rod is fixedly connected to the rotating ring.

[0014] Furthermore, the cooling chamber is equipped with a control panel, which is connected to a two-way fan, an electric telescopic tube, and a drive motor.

[0015] Furthermore, a cooling method for coal mine electromechanical equipment includes the following specific steps: S1. First, the staff placed the coal mine mechanical and electrical equipment that needed to be cooled inside the cooling chamber. Then, they controlled the rubber plate to move upward and sealed the separation groove at the bottom of the cleaning box. The air outlet pipe started to draw in air and transmitted the gas to the cooling chamber through the air outlet pipe to carry out the initial dust removal and cooling operation on the coal mine mechanical and electrical equipment. S2. Subsequently, since dust and debris often adhere to the surface of coal mine electromechanical equipment, stone fragments and some heat are drawn into the interior of the conical cylinder. After the stone fragments and other impurities enter the interior of the conical cylinder, they pass through the spiral air duct opened inside. As they spiral along the spiral air duct, they come into contact with the crushing rod installed inside and collide with each other to crush them, and are blocked by the filter plate. S3. After cleaning is complete, reset the rubber plate to open the separation tank. At this time, the debris filtered by the filter plate inside the cleaning box will fall out of the separation tank. Then, control the cleaning component to reverse and enter the formal cooling operation. S4. Finally, because the filter plate can deform to a certain extent, when the cooling gas is blown into the interior of the cleaning box, the filter plate deforms downwards, thus taking on a trapezoidal shape. At this time, the mesh on the surface of the filter plate will be blocked due to deformation. The impurities attached to its surface will be blown out from the separation tank along the trapezoidal filter plate. Since two sets of cleaning components are set, when one set of components is sucking air, the other set of components blows air, so that they cooperate with each other until the cooling is completed.

[0016] The beneficial effects of this invention are as follows: 1. This invention achieves efficient cleaning of coal mine electromechanical equipment by alternating the use of two sets of cleaning components. While one set of components performs suction, the other set blows air outward. This maintains a negative pressure state within the cooling chamber during the cleaning process, effectively removing dust and debris, ensuring the equipment surface is free of dust, thus providing a good foundation for subsequent cooling preparation. During the cleaning process, the cleaning components not only remove physical impurities but also reduce the surface temperature of the equipment to a certain extent.

[0017] 2. During the suction process, the airflow inside the cleaning box carries away some of the heat from the coal mine's electromechanical equipment, allowing it to reach a more suitable temperature before cooling down. This prevents the generation of water vapor during rapid cooling and avoids damage to the equipment due to sudden temperature drops. Because two sets of cleaning components work alternately, while one set is suctioning, the other is blowing air, creating a good airflow circulation. This design not only improves cleaning efficiency but also ensures that the inside of the cleaning components is effectively cleaned, preventing performance degradation caused by dust accumulation.

[0018] 3. In this invention, when the filter plate is shaped into a trapezoidal structure, the trapezoidal structure enhances the impact force of the airflow, allowing the gas to better detach attached impurities as it passes through the filter plate. The oblique angle of the airflow causes dirt to slide down the filter plate, improving the cleaning effect. Through this design, the filter plate not only passively filters during use but also has the ability to actively clean itself. As airflow continues to blow in, impurities on the filter plate can be gradually removed, maintaining a good working condition. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] A preferred embodiment of the present invention, a cooling device and method for coal mine electromechanical equipment, will be described in detail below.

[0023] Example 1, as Figures 1-8 As shown, it includes a cooling chamber 1 and a cooling cylinder 2. The cooling cylinder 2 is equipped with a cleaning component 3, which consists of a cleaning mechanism 4 and a sealing mechanism 5. The cleaning mechanism 4 includes a cleaning box 41 installed inside the cooling cylinder 2. The cleaning box 41 has a filter plate 42 installed inside. The filter plate 42 can deform to a certain extent. A separation groove 43 is opened on the surface of the cleaning box 41 and below the filter plate 42. A conical cylinder 44 is installed below the cleaning box 41. A spiral air duct 45 is opened inside the conical cylinder 44. A crushing rod 46 is fixedly installed inside the conical cylinder 44. An air inlet pipe 47 and an air outlet pipe 48 are fixedly connected to one side of the cleaning box 41 and the conical cylinder 44, respectively. Two sets of cleaning components 3 are symmetrically arranged and can perform air intake and air blowing operations on the cooling chamber 1. The cleaning components 3 can rotate inside the cooling cylinder 2. The sealing mechanism 5 includes a rubber plate 51 disposed inside the cleaning box 41. The rubber plate 51 is located below the filter plate 42. The rubber plate 51 can move inside the cleaning box 41 and seal the separation groove 43. First, the workers place the coal mine machinery and equipment requiring cooling inside the cooling chamber 1. Then, they control the rubber plate 51 to move upwards, sealing the separation groove 43 at the bottom of the cleaning box 41. The exhaust pipe 48 then begins to draw in air. The suction gas generated by the exhaust pipe 48 enters from the cleaning box 41, passes through the conical cylinder 44, and is then transported to the interior of the cooling chamber 1 through the inlet pipe 47. This draws in the dust, stone fragments, and some heat generated by the coal mine machinery and equipment during operation into the conical cylinder 44. After entering the conical cylinder 44, the stone fragments and other impurities are further processed by the spiral airflow inside. The gas spirals into the cleaning box 41 through the spiral air duct 45. As the gas spirals along the duct 45, it comes into contact with and collides with the crushing rod 46 installed inside, thus crushing larger pieces of stone into smaller particles. The particles then enter the cleaning box 41 and are filtered by the filter plate 42. The hot gas and dust are sucked away. Thus, before the formal cooling, the coal mine equipment is cleaned and cooled down at the same time, preventing the formation of water vapor due to rapid cooling when the coal mine equipment comes into contact with the cooling gas during the subsequent cooling process. After cleaning is completed, the rubber plate 51 is reset, and the separation tank 43 is opened. At this time, the debris filtered by the filter plate 42 inside the cleaning box 41 will fall out from the separation tank 43, thereby cleaning the cleaning box 41. The operator can then control the cleaning component 3 to reverse, so that the cone 44 located below rotates to the top. Then, the air inlet pipe 47 is controlled to send the cooling gas back into the cone 44 and then into the interior of the cleaning box 41. Since the filter plate 42 can undergo a certain deformation, when the cooling gas is blown into the interior of the cleaning box 41, the filter plate 42 deforms downward, thus presenting a trapezoidal shape. At this time, the mesh on the surface of the filter plate 42 will be blocked due to deformation. At this time, the impurities attached to its surface will be blown out from the separation tank 43 along the trapezoidal filter plate 42 and fall into the cooling cylinder 2 for collection. Since two sets of cleaning components 3 are set, when one set of components is sucking air, the other set of components blows air, so that they cooperate with each other. By alternating the use of two sets of cleaning components 3, efficient cleaning of coal mine electromechanical equipment can be achieved. While one set of components is performing suction, the other set is responsible for blowing air outward. This maintains a negative pressure state within the cooling chamber 1 during the cleaning process, effectively removing dust and debris, ensuring the equipment surface is free of dust, thus providing a good foundation for subsequent cooling. During the cleaning process, the cleaning components 3 not only remove physical impurities but also reduce the surface temperature of the equipment to a certain extent. During suction, the airflow inside the cleaning box 41 carries away some heat from the coal mine electromechanical equipment, allowing the equipment to reach a more suitable temperature before cooling, preventing the generation of water vapor during rapid cooling, and avoiding damage to the equipment due to sudden temperature drops. Because the two sets of cleaning components 3 work alternately, with one set suctioning while the other blows air, a good airflow circulation is formed. This design not only improves cleaning efficiency but also ensures that the inside of the cleaning components 3 is effectively cleaned, avoiding performance degradation caused by dust accumulation.

[0024] Example 2, as Figures 1-7 As shown, a movable part 6 is provided inside the cleaning box 41. A rotating part 7 is fixedly installed on one side of the movable part 6. A first connecting rod 8 is fixedly installed on one side of the rotating part 7. An installation ring 9 is fixedly installed inside the cleaning box 41. A second connecting rod 10 is fixedly installed on the inner wall of the installation ring 9. At least six sets of rotating parts 7 and second connecting rods 10 are arranged in a ring. The first connecting rod 8 passes through and extends into the interior of the second connecting rod 10. At least six sets of filter plates 42 are arranged in a ring and are fixedly connected to the first connecting rod 8 and the second connecting rod 10. When the gas is blown into the interior of the cleaning box 41, the moving part 6 will be blown and move downward. The moving part 6 will simultaneously drive the rotating part 7 to move. The rotating part 7 will drive the first connecting rod 8 to rotate and cause the first connecting rod 8 to slide and extend inside the second connecting rod 10, thereby causing the filter plate 42 to deform, so that the filter plate 42 takes the shape of a ladder. During the cooling air blowing, the debris on the surface of the filter plate 42 can be cleaned by the oblique angle of the filter plate 42. When the filter plate 42 is shaped into a trapezoidal structure, the trapezoidal structure increases the impact force of the airflow, allowing the gas to better remove attached impurities as it passes through the filter plate 42. The oblique angle of the airflow causes dirt to slide down the filter plate 42, improving the cleaning effect. Through this design, the filter plate 42 not only passively filters during use but also has the ability to actively clean itself. As airflow continues to blow in, impurities on the filter plate 42 can be gradually removed, maintaining a good working condition.

[0025] Example 3, as Figures 1-8 As shown, a transmission tube 52 is provided inside the cleaning box 41. The transmission tube 52 passes through and extends to the bottom of the cleaning box 41. An elastic ring 53 is provided inside the cleaning box 41. The elastic ring 53 fits against the inner wall of the cleaning box 41. A first sliding rod 54 is fixedly installed on the surface of the transmission tube 52. A second sliding rod 55 is fixedly installed on the inner wall of the elastic ring 53. The first sliding rod 54 passes through and extends into the interior of the second sliding rod 55. A connecting spring 56 is fixedly installed between the inner walls of the first sliding rod 54 and the second sliding rod 55. At least six sets of the first sliding rod 54 and the second sliding rod 55 are arranged in a ring. When the conical cylinder 44 moves upward, it drives the transmission pipe 52 to move upward synchronously. When the transmission pipe 52 moves upward, it can drive the first sliding rod 54 to move. The first sliding rod 54 drives the elastic ring 53 to move through the second sliding rod 55. At the same time, the connecting spring 56 pushes the second sliding rod 55 out due to elastic potential energy, causing the elastic ring 53 to expand due to elastic potential energy, thereby sealing the separation groove 43.

[0026] Example 4, as Figures 1-6 As shown, the air inlet pipe 47 and the air outlet pipe 48 are respectively provided with a first connecting pipe 11 and a second connecting pipe 12 on one side. An electric telescopic pipe 13 is fixedly installed on the opposite side of the first connecting pipe 11 and the second connecting pipe 12. A bidirectional fan 14 is fixedly installed on the surface of the cooling cylinder 2. The first connecting pipe 11 and the second connecting pipe 12 are fixedly connected to the bidirectional fan 14. The bidirectional fan 14 can be used to cool the coal mine electromechanical equipment in the cooling chamber 1 by drawing in and blowing air. The electric telescopic pipe 13 can be extended and retracted, and then connected to the air inlet pipe 47 and the air outlet pipe 48.

[0027] Example 5, such as Figures 1-8 As shown, the cooling cylinder 2 has a rotating ring 15 inside, which is fixedly connected to the surface of the cleaning box 41. A drive motor 16 is fixedly installed on one side of the cooling cylinder 2. A drive rod 17 is fixedly installed at the output end of the drive motor 16 and is fixedly connected to the rotating ring 15. The cooling chamber 1 has a control panel inside, which is connected to the bidirectional fan 14, the electric telescopic tube 13, and the drive motor 16. When the drive motor 16 starts, it can drive the rotating ring 15 to rotate through the drive rod 17, thereby realizing the rotation of the cleaning component 3 and realizing the cleaning and cooling operation of the coal mine electromechanical equipment inside the cooling chamber 1.
