Description

Technical Field

[0001] The present invention relates to the technical field of equipment cooling, and more specifically, to a cooling device for mechanical equipment. Background Art

[0002] A cooler is a type of heat exchange equipment used to cool fluids, and it usually uses water or air as a coolant to remove heat. Due to the large variety of coolers, when cooling different high-power electrical appliances, in order to improve the cooling efficiency, a mixed method of water cooling and air cooling is chosen.

[0003] According to Chinese patent number CN112325547B, the heat dissipation device can be easily disassembled by adjusting the part that needs cooling, preventing the heat dissipation device from being flooded when the water tank is replaced and affecting its use. The heat on the second heat sink is brought to the first heat sink through water circulation, and the swinging fan blows evenly to the first heat sink to increase the cooling effect. It can automatically operate according to the temperature and reduce the waste of electricity.

[0004] However, when the above scheme is implemented, it utilizes the combination of water cooling and air cooling to improve the cooling effect. However, when the water pipes circulate for a long time, scale may clog the inside and the connecting ends of the water pipes may become loose due to the impact of the water flow. Therefore, we propose a cooling device for mechanical equipment. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a cooling device for mechanical equipment, which sets the direction of water flow from the cooling water pipe to the backflow arc groove. When the corresponding push rod is circulated and transmitted by the water flow, the corresponding push rod is impacted by the water flow, causing the corresponding push rod to drive the auxiliary push block and the arc rubber rod along the inner cavity of the hollow guide groove frame to insert into the arc access groove, and the limit block limits the auxiliary push block, and the air between the arc rubber rod and the arc access groove is squeezed out, so that the air pressure principle is used between the two to cause the two to generate a larger stabilizing force to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling device for mechanical equipment, comprising a cooling device frame, wherein a mechanical equipment mounting frame for mounting mechanical equipment is provided inside the cooling device frame, and both ends of the cooling device frame are fixedly connected with connected cooling water pipes, one end of the cooling water pipe is fixedly connected with a cooling assembly, and a connecting and positioning hollow pipe is inserted into the outer surface of the cooling water pipe, and the connecting and positioning hollow pipe connects and fixes multiple sections of cooling water pipes, and one end of the cooling water pipe is connected to the cooling assembly for water circulation cooling; The outer surface of the cooling water pipe is provided with a backflow arc groove for directional conduction of water flow, the inner wall of the cooling water pipe is fixedly connected with a corresponding push rod through the backflow arc groove, the outer surface of the corresponding push rod is plugged with a hollow guide groove frame, the hollow guide groove frame is fixedly installed on the inner wall of the connection and positioning hollow pipe, the end of the corresponding push rod inserted into the hollow guide groove frame is fixedly connected with an auxiliary push block, and the interior of the hollow guide groove frame is fixedly connected with two sets of limit blocks; The two groups of limit blocks are located on both sides of the auxiliary pushing block. The auxiliary pushing block passes through one end of the hollow guide groove frame and is fixedly connected to a spring rod.

[0008] In a preferred embodiment, there are multiple groups of connecting and positioning hollow tubes, and linkage clamp frames are fixedly connected between the multiple groups of connecting and positioning hollow tubes. A turning rail is provided at the connection between the connecting and positioning hollow tubes and the cooling water pipes. A plastic descaling fan is rotatably connected to the connection between the connecting and positioning hollow tubes and the cooling water pipes through the turning rail. A hollow mounting frame is fixedly connected to the inner wall of the plastic descaling fan. As the corresponding rotating rod drives the cooling fan blades to rotate, the wind generated by the cooling fan blades causes the plastic descaling fan to deflect.

[0009] In a preferred embodiment, two groups of hollow guide rails are provided inside the hollow mounting frame, and a pushing rod is slidably connected to the inside of the hollow mounting frame through the two groups of hollow guide rails. A positioning air pressure chamber arranged in a sealed state is provided inside the hollow mounting frame, and a rubber expansion ring is inserted at one end of the hollow mounting frame. The rubber expansion ring and the hollow mounting frame are filled with sealant and arranged in a sealed state. When the plastic descaling fan is deflected a small distance by the turning rail, the plastic descaling fan drives multiple groups of hollow mounting frames to deflect synchronously. Since the rubber stretching ring is made of rubber, the plastic descaling fan uses the rubber tension of the sealing rubber to drive the sealing rubber to deform when it is deflected, but the plastic descaling fan still remains sealed with the cooling water pipe.

[0010] In a preferred embodiment, the rubber expansion ring is slidably connected to the inside of the cleaning plug-in arc plate, and the inside of the cleaning plug-in arc plate is fixedly connected to a curved small spring, and the curved small spring is fixedly connected to one end of the cleaning plug-in arc plate.

The rubber expansion ring is rotatably connected to the surface of the cooling water pipe through a slewing track. The slewing track is set as a short arc long track, and the plastic descaling fan can only be deflected a short distance along the short arc long track.

[0012] In a preferred embodiment, a filter card door is hinged on the outer surface of the cooling device frame, one end of the filter card door is fixedly connected to a handle, the interior of the filter card door is fixedly connected to a heat dissipation filter, the bottom end of the cooling device frame is fixedly connected to a corresponding positioning base, one end of the corresponding positioning base is fixedly connected to a limited position plug-in fixed plate, and the limited position plug-in fixed plate is located below the filter card door. The staff grasps the handle to drive the filter card door to deflect with the cooling device frame as a reference point, and moves the heat dissipation filter out of the filter card door for cleaning.

[0013] Technical effects and advantages of the present invention: 1. The water flow is set to be transmitted from the cooling water pipe to the reverse flow arc groove. When the corresponding push rod is subjected to the circulation transmission of the water flow, the corresponding push rod is impacted by the water flow, causing the corresponding push rod to drive the auxiliary push block and the arc rubber rod along the inner cavity of the hollow guide groove frame to insert into the arc access groove, and the limit block limits the auxiliary push block. The air between the arc rubber rod and the arc access groove is squeezed out, and the air pressure principle is used between the two to generate a larger stabilizing force. The auxiliary push block is difficult to escape from the arc access groove, and the cooling water pipe and the connection positioning hollow pipe have greater connectivity, thereby improving the stability of the connection between the cooling pipes and avoiding water flow penetration; 2. The positioning air pressure chamber drives the push rod to slide inside the hollow guide rail through the pressure inside the cooling water pipe, reducing the impact of air pressure on the inner wall of the cooling water pipe. When the water flow returns to normal, the internal air pressure stabilizes, causing the positioning air pressure chamber to return to its original position, thereby preventing dirt from clogging the inside of the water pipe and preventing the inside of the water pipe from being damaged by water pressure and sealed air pressure.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Refer to the instruction manual Figure 1-5 A cooling device for mechanical equipment according to an embodiment of the present invention comprises a cooling device frame 1, a mechanical equipment mounting frame 2 for mounting mechanical equipment is provided inside the cooling device frame 1, cooling water pipes 3 are fixedly connected to both ends of the cooling device frame 1, one end of the cooling water pipe 3 is fixedly connected to a cooling assembly, a connecting and positioning hollow pipe 4 is inserted into the outer surface of the cooling water pipe 3, the connecting and positioning hollow pipe 4 connects and fixes multiple sections of cooling water pipes 3, and one end of the cooling water pipe 3 is connected to the cooling assembly for water circulation cooling; The outer surface of the cooling water pipe 3 is provided with a backflow arc groove 24 which is convenient for directional conduction of water flow. The inner wall of the cooling water pipe 3 is fixedly connected with a corresponding push rod 25 through the backflow arc groove 24. The outer surface of the corresponding push rod 25 is plugged with a hollow guide groove frame 26. The hollow guide groove frame 26 is fixedly installed on the inner wall of the connected and positioned hollow tube 4. One end of the corresponding push rod 25 inserted into the hollow guide groove frame 26 is fixedly connected with an auxiliary push block 27. The interior of the hollow guide groove frame 26 is fixedly connected with two sets of limit blocks 28.

[0025] Furthermore, two groups of limit blocks 28 are located on both sides of the auxiliary pushing block 27. The auxiliary pushing block 27 passes through one end of the hollow guide groove frame 26 and is fixedly connected to a spring rod 29. The spring rod 29 buffers the impact force of the corresponding pushing rod 25 to prevent the arc rubber rod 30 from being damaged by external force. One end of the spring rod 29 is fixedly connected to the arc rubber rod 30. One end of the hollow guide groove frame 26 is fixedly connected to a fixed hollow block 32. The corresponding pushing rod 25 passes through the hollow guide groove frame 26 and is inserted into the interior of the fixed hollow block 32. The water flow is set to be transmitted from the cooling water pipe 3 to the reverse flow arc groove 24. When the corresponding pushing rod 25 is subjected to the water flow circulation transmission, the corresponding pushing rod 25 is subjected to the water flow. The collision causes the corresponding pushing rod 25 to drive the auxiliary pushing block 27 and the arc-shaped rubber rod 30 along the inner cavity of the hollow guide groove frame 26 to insert into the arc-shaped access groove 31, and the limiting block 28 limits the auxiliary pushing block 27. At the same time, the limiting block 28 is used to seal the auxiliary pushing block 27 and the arc-shaped access groove 31. The air between the arc-shaped rubber rod 30 and the arc-shaped access groove 31 is squeezed out, and a greater stabilizing force is generated between the two through the air pressure principle. It is difficult for the auxiliary pushing block 27 to escape from the arc-shaped access groove 31, and greater connectivity is generated between the cooling water pipe 3 and the connecting positioning hollow pipe 4, thereby improving the stability of the connection between the cooling pipes and avoiding water penetration.

[0026] Refer to the instruction manual Figure 3-7 An arc-shaped access groove 31 is provided inside the fixed hollow block 32, and one end of the auxiliary pushing block 27 passing through the fixed hollow block 32 is fixedly connected to an arc-shaped rubber rod 30 through a spring rod 29. The arc-shaped rubber rod 30 and the arc-shaped access groove 31 are arranged in a sealed state. The diameter of the arc-shaped rubber rod 30 is larger than the aperture of the hollow guide groove frame 26. The fixed hollow block 32 is fixedly connected to one end of the connecting and positioning hollow tube 4. Since the diameter of the arc-shaped rubber rod 30 is larger than the aperture of the hollow guide groove frame 26, the arc-shaped rubber rod 30 will not fall off from the fixed hollow block 32.

[0027] Refer to the instruction manual Figure 1-2 There are multiple groups of connecting and positioning hollow tubes 4, and linkage clamp frames 8 are fixedly connected between the multiple groups of connecting and positioning hollow tubes 4. A turning rail is provided at the connection between the connecting and positioning hollow tubes 4 and the cooling water pipe 3. The connection between the connecting and positioning hollow tubes 4 and the cooling water pipe 3 is rotatably connected with a plastic descaling fan 7 through the turning rail. The inner wall of the plastic descaling fan 7 is fixedly connected with a hollow mounting frame 21. As the corresponding rotating rod 12 drives the cooling fan blades 6 to rotate, the blowing generated by the cooling fan blades 6 deflects the plastic descaling fan 7.

[0028] Furthermore, two groups of hollow guide rails 23 are provided inside the hollow mounting frame 21, and the pushing rod 22 is slidably connected to the inside of the hollow mounting frame 21 through the two groups of hollow guide rails 23. A positioning air pressure chamber 19 set in a sealed state is provided inside the hollow mounting frame 21, and a rubber expansion ring 16 is inserted at one end of the hollow mounting frame 21. The rubber expansion ring 16 and the hollow mounting frame 21 are filled with sealant and set in a sealed state. The plastic descaling fan 7 is deflected a small distance by the turn rail, and the plastic descaling fan 7 drives multiple groups of hollow mounting frames 21 to deflect synchronously. Since the rubber stretching ring 20 is made of rubber, the plastic descaling fan 7 uses the rubber tension of the sealing rubber to drive the sealing rubber to deform when deflected, but the plastic descaling fan 7 still maintains a sealed state with the cooling water pipe 3, and the dirt on the inner wall of the cooling water pipe 3 The scale is cleaned by the rotation of the rubber expansion ring 16 and the long brush plate installed on the cleaning plug-in arc plate 17 to clean the inner wall of the cooling water pipe 3. Since the cooling water pipe 3 is connected in multiple sections, when the cooling effect is accelerated, the transmission speed of the water flow will become faster, and the rubber expansion ring 16 is in an expansion and contraction state by relying on the curved small spring 18, so that the cooling water pipe 3 always maintains a stable connection. At the same time, the impact of the water flow will change the pressure on the inner wall of the pipe. The positioning air pressure chamber 19 drives the push rod 22 to slide inside the hollow guide rail 23 through the pressure inside the cooling water pipe 3, thereby reducing the influence of air pressure on the inner wall of the cooling water pipe 3. When the water flow returns to normal, the internal air pressure is stable, causing the positioning air pressure chamber 19 to return to its original position, thereby preventing dirt from clogging the inside of the water pipe and preventing the inside of the water pipe from being damaged by water pressure and sealed air pressure.

[0029] Refer to the instruction manual Figure 1-4 The rubber expansion ring 16 is slidably connected to a cleaning plug-in arc plate 17, and a curved small spring 18 is fixedly connected to the inside of the cleaning plug-in arc plate 17. The curved small spring 18 is fixedly connected to one end of the cleaning plug-in arc plate 17. There are multiple groups of hollow mounting frames 21, and rubber stretch rings 20 are fixedly connected between the multiple groups of hollow mounting frames 21. The rubber expansion ring 16 is rotatably connected to the surface of the cooling water pipe 3 through a turntable. The turntable is set as a short arc long track. The plastic descaling fan 7 can only be deflected a short distance along the short arc long track, and the cooling device frame 1 is away from the mechanical equipment mounting frame 2 One end of the motor 14 is fixedly connected to a corresponding rotating rod 12, one end of the corresponding rotating rod 12 is fixedly connected to an auxiliary rotating disk 13, there are multiple groups of auxiliary rotating disks 13, the outer surfaces of the multiple groups of auxiliary rotating disks 13 are connected with auxiliary transmission belts 15, the motor 14 drives the auxiliary rotating disk 13 to rotate, the auxiliary rotating disk 13 relies on the transmission of the auxiliary transmission belt 15 to cause the multiple groups of corresponding rotating rods 12 to rotate synchronously, the corresponding rotating rods 12 drive the multiple groups of cooling fan blades 6 to rotate, quickly dissipate the water flow inside the cooling water pipe 3, and realize the operation of water cooling and air cooling together.

[0030] Furthermore, a filter clamping door 5 is hingedly connected to the outer surface of the cooling device frame 1, one end of the filter clamping door 5 is fixedly connected to a handle, a heat dissipation filter 9 is fixedly connected to the inside of the filter clamping door 5, and a corresponding positioning base 11 is fixedly connected to the bottom end of the cooling device frame 1, and one end of the corresponding positioning base 11 is fixedly connected to a limited position plug-in fixed plate 10, and the limited position plug-in fixed plate 10 is located below the filter clamping door 5. The staff grasps the handle to drive the filter clamping door 5 to deflect with the cooling device frame 1 as the reference point, and removes the heat dissipation filter 9 from the filter clamping door 5 for cleaning; The cold air flow fanned by the cooling fan blades 6 blows toward the mechanical equipment installed in the mechanical equipment mounting frame 2 to cool it, and moves the dirt on the mechanical equipment to the heat dissipation filter 9. The heat dissipation filter 9 isolates the dirt in the air flow to prevent it from floating in the air.
