[0040] Example 1

[0041] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a heat dissipation device for mechanical equipment, including a hoist assembly 100, which includes a hoist motor body 101, a cooling box 102 arranged on one side of the hoist motor body 101 for cooling the lubricating oil in the hoist motor body 101, and a plurality of cooling holes 104 distributed at intervals are opened inside the cooling box 102;

[0042] The heat dissipation assembly 200 includes a heat dissipation base 201 installed at the bottom of the cooling box 102, a rotating heat dissipation mechanism 202 for controlling gas circulation is provided in the middle of the heat dissipation base 201, and a heat dissipation fan 203 for extracting gas for heat dissipation is provided above the rotating heat dissipation mechanism 202;

[0043] The fresh air component 300 includes a rotating opening and closing mechanism 301 arranged inside the rotating heat dissipation mechanism 202, a fixing mechanism 302 is sleeved on the outer side of the rotating opening and closing mechanism 301, and a spare heat dissipation channel is formed between the rotating opening and closing mechanism 301 and the fixing mechanism 302. The rotating opening and closing mechanism 301 is driven by the rotating heat dissipation mechanism 202 to control the opening or closing of the spare heat dissipation channel.

[0044] The cooling box 102 is arranged on one side of the motor body 101, and contains a plurality of cooling holes and grooves 104. These holes and grooves can increase the contact area with the cooling thermal expansion medium such as air, thereby effectively reducing the temperature of the lubricating oil inside the motor and preventing performance degradation and damage caused by overheating; the heat dissipation base 201 is installed at the bottom of the cooling box 102 to provide support for the entire heat dissipation device; the heat dissipation fan 203 is arranged above the rotating heat dissipation mechanism 202 to extract gas for heat dissipation, accelerate air circulation, and further improve cooling efficiency; the fixing mechanism 302 is mounted on the outside of the rotating opening and closing mechanism 301, and the spare heat dissipation channel formed between the fixing mechanism 302 and the rotating opening and closing mechanism 301 can be used as a backup solution when the main heat dissipation path is blocked or fails, ensuring the stable operation of the device; through the intelligent control of the rotating opening and closing mechanism 301, the heat dissipation strategy can be automatically adjusted according to the actual working conditions, energy waste can be reduced, and the energy efficiency ratio of the overall system can be improved.

[0045] Example 2

[0046] Reference Figure 3-4, which is the second embodiment of the present invention. Different from the previous embodiment, the rotating heat dissipation mechanism 202 includes a heat dissipation port 202a for gas circulation provided on the heat dissipation base 201, a hollow turntable 202b is rotatably provided inside the heat dissipation port 202a, an arc groove 202d is correspondingly provided on the hollow turntable 202b, a blocking slide 202e is provided below the heat dissipation port 202a, and the top of the blocking slide 202e extends into the arc groove 202d, and is pushed by the arc groove 202d to close or open the heat dissipation port 202a; wherein, two blocking slides 202e are symmetrically arranged, and a slide groove for guiding the sliding of the blocking slide 202e is provided inside the heat dissipation port 202a. A limiting mechanism 202f is provided on one side of the hollow turntable 202b to limit the hollow turntable 202b, a limiting block is provided on the top of the arc groove 202d, a limiting groove engaged with the limiting block is provided on one side of the hollow turntable 202b, a heat expansion medium is added inside the arc groove 202d, and the heat expansion medium expands when heated to push the limiting block to move and release the limit on the hollow turntable 202b. A scroll spring 202g is provided below the hollow turntable 202b, and the scroll spring 202g applies a torsion force to the hollow turntable 202b to drive the hollow turntable 202b to rotate to a preset angle.

[0047] The heat dissipation port 202a serves as a channel for gas circulation to help the equipment dissipate heat. By controlling the opening and closing of the heat dissipation port 202a, the heat dissipation efficiency can be adjusted to adapt to different working environments; the blocking slide 202e opens or closes the heat dissipation port 202a by extending into the arc groove 202d; the slide groove guides the blocking slide 202e to slide along a predetermined path to ensure the smoothness of the movement of the blocking slide 202e and avoid jamming; the limiting mechanism 202f ensures that the hollow turntable 202b can only rotate under specific conditions, thereby improving the controllability and stability of the system; the limiting block and the limiting groove cooperate with the limiting mechanism 202f to release the limit on the hollow turntable 202b through the thermal expansion of the thermal expansion medium, thereby realizing temperature-sensitive automatic control; the volute spring 202g provides the torque required for the rotation of the hollow turntable 202b, thereby ensuring that the hollow turntable 202b can quickly and accurately reach the preset angle, thereby improving the response speed and accuracy of the device.

[0048] The rotating opening and closing mechanism 301 includes an inner disk 301a that is coaxially rotatable with the hollow rotating disk 202b, a first gear 301c is provided between the inner disk 301a and the hollow rotating disk 202b, and a tooth groove 301d that meshes with the first gear 301c is provided between the hollow rotating disk 202b and the inner disk 301a. The fixing mechanism 302 includes an outer disk 302a that is fixed on the inner wall of the heat dissipation port 202a, a second blocking plate 302b is fixed to the inner wall of the outer disk 302a at intervals, and a first blocking plate 301b is fixed to the outer side of the inner disk 301a at intervals. When the inner disk 301a rotates to drive multiple inner disks 301a to change position, the standby heat dissipation channel is opened or closed; wherein, a standby heat dissipation pipe 204 is fixed to the outer side of the heat dissipation base 201, and the air inlet end of the standby heat dissipation pipe 204 is connected to the outer disk 302a to transport gas.

[0049] refer to Figure 1-3 In this embodiment, when in use, the cooling box 102 circulates the lubricating oil in the lifting motor body 101 to the cooling box 102 through the connected pipeline through an external power device such as a circulating pump. The thermostat inside the cooling box 102 will detect the temperature of the lubricating oil. When the temperature of the lubricating oil exceeds the preset value, the thermostat will turn on the power of the cooling fan 203. When the cooling fan 203 rotates, it blows wind out from the cooling hole groove 104 inside the cooling box 102, thereby effectively cooling the lubricating oil.

[0050] The cooling box 102 is provided with an "S"-shaped cooling channel, which effectively improves the heat exchange efficiency between the lubricating oil and the air cooling.

[0051] This device requires sufficient air circulation to effectively dissipate heat, but in some environments, such as small spaces or closed environments, air circulation is limited, resulting in poor heat dissipation.

[0052] refer to Figure 3-4 When the cooling box 102 has a poor heat dissipation effect, the internal temperature will rise. When the temperature rises to a preset range, such as 65°, the heat expansion medium inside the limiting mechanism 202f absorbs heat and expands. The limiting mechanism 202f is composed of a telescopic tube, a telescopic rod and a reset spring. Therefore, the telescopic rod will drive the top limit block to rise rapidly under the push of the thermal expansion medium, thereby separating from the limit groove. The hollow turntable 202b is now released from the constraint. The hollow turntable 202b rotates to a preset angle under the push of the torsion of the volute spring 202g, and the hollow turntable 202b pushes the blocking slide 202e to slide through the arc groove 202d when rotating, so that the two blocking slides 202e are close to each other, thereby blocking the heat dissipation port 202a, and preventing the cooling fan 203 from extracting the surrounding high-temperature gas again;

[0053] When the hollow turntable 202b rotates, the meshing first gear 301c drives the inner disk 301a to rotate. When the inner disk 301a rotates, the first blocking plate 301b and the second blocking plate 302b are separated, thereby opening the spare heat dissipation channel formed between the inner disk 301a and the outer disk 302a. Therefore, the cooling fan 203 extracts cold air in the spare heat dissipation channel to effectively cool the lubricating oil.

[0054] refer to Figure 2 and Figure 4 It should be noted that the standby heat dissipation channel is connected to the standby heat dissipation pipe 204. By adjusting the length of the standby heat dissipation pipe 204, the air inlet of the standby heat dissipation pipe 204 is located outside the computer room, so that the external cold air can be effectively extracted to achieve rapid cooling.

[0055] The built-in thermostat can monitor the lubricating oil temperature in real time. Once the temperature exceeds the preset value, the system will automatically start the cooling fan to cool it down and ensure that the lubricating oil is within the appropriate working temperature range.

[0056] Adaptive Environmental Adjustment In an environment with limited air flow, the limit mechanism 202f can automatically adjust the heat dissipation mode according to the change of internal temperature. When the temperature rises, the limit mechanism 202f will trigger a series of actions, including closing the main heat dissipation port 202a to prevent the inhalation of hot air, and opening the backup heat dissipation channel to introduce cooler air.

[0057] Flexible backup heat dissipation solution The backup heat dissipation channel is connected to the outside world through a backup heat dissipation pipe. The length of the heat dissipation pipe 204 can be adjusted according to actual conditions so that its air inlet is located in a cooler environment, further improving the cooling efficiency.

[0058] Example 3

[0059] Reference Figure 2-Figure 4 -5 is the third embodiment of the present invention, which further provides a heat dissipation device for mechanical equipment. An external arc-shaped toothed plate 401 is fixed above the inner disk 301a, and a rack 402 is arranged on the outer periphery of the external arc-shaped toothed plate 401. The external arc-shaped toothed plate 401 and the rack 402 are meshed through a second gear 403 to drive the rack 402 to slide. A sliding frame 402b is arranged on one side of the rack 402 to guide the rack 402 to slide, and a magnetic sheet 402a is fixed on one end of the rack 402. An electromagnet is arranged inside the sliding frame 402b to apply magnetic force to the magnetic sheet 402a to push the rack 402 to reset.

[0060] In this embodiment, the external arc-shaped tooth plate 401 is driven by the inner disk 301a to rotate synchronously. When the external arc-shaped tooth plate 401 rotates, the gear rack 402 is pushed toward the electromagnet through the meshing second gear 403. When the device is shut down and restarted, the electromagnet is powered for 3-5 seconds through relays and other equipment. The repulsive force generated by the electromagnet on the magnetic sheet 402a pushes the gear rack 402 to slide and reset. When the gear rack 402 is reset, it can be obtained by the same token that the hollow turntable 202b will eventually be driven to rotate to the initial position, thereby being limited by the limit block on the limit mechanism 202f. Therefore, the device can be automatically reset and reused.

[0061] An elastic tube 404 is provided at one end of the rack 402 away from the magnetic sheet 402a, and a solution is filled inside the elastic tube 404. A filter 205 for filtering dust is installed below the heat dissipation port 202a, a brush 406 for cleaning the filter 205 is provided below the filter 205, and a hydraulic rotating mechanism 405 for driving the brush 406 to rotate is provided below the brush 406. The elastic tube 404 and the hydraulic rotating mechanism 405 are connected through a hose to apply a driving force to the brush 406, and the hydraulic rotating mechanism 405 is fixed to the heat dissipation base 201 through a bracket.

[0062] In this embodiment, during use, the filter 205 can be installed to filter the dust contained in the external air, effectively reducing the dust from adhering to the cooling hole groove 104, thereby avoiding reducing the heat dissipation effect;

[0063] In addition, the rack 402 will squeeze the elastic tube 404 during the resetting process, and the solution in the elastic tube 404 will be squeezed into the hydraulic rotating mechanism 405 through the hose. The rotation axis of the hydraulic rotating mechanism 405 drives the brush 406 to rub and clean the surface of the filter 205 to prevent the filter 205 from being blocked, resulting in a decrease in the air intake and a weakened cooling effect on the lubricating oil, which may cause false triggering.

[0064] The hydraulic rotating mechanism 405 includes an arc groove opened inside, and one side of the rotating shaft is located in the arc groove. When the solution enters the arc groove, the pressure generated pushes the rotating shaft of the hydraulic rotating mechanism 405 to rotate, and a torsion spring is sleeved on the rotating shaft to facilitate resetting.
