Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A torque overload one-way protector structure based on an industrial machinery drive shaft includes a torque overload one-way protector 1. A heat dissipation mechanism 2 is externally provided for dissipating heat from the torque overload one-way protector 1. The heat dissipation mechanism 2 includes:

[0026] The housing unit 21 is disposed outside the torque overload one-way protector 1, including a housing 211 fixedly installed inside the left flange of the torque overload one-way protector 1, and a rotating ring 212 fixedly installed inside the right flange of the torque overload one-way protector 1, and the housing 211 and the rotating ring 212 are rotatably connected.

[0027] The air blowing unit 22 is located above the housing 211 and includes a top square box 221 fixedly installed on the top of the torque overload unidirectional protector 1. A grid plate 222 is fixedly installed on the top of the housing 211, and a fan 223 is fixedly installed on the bottom of the grid plate 222. The fan 223 blows air to cool the inside of the housing 211.

[0028] The suction unit 23 is located below the torque overload unidirectional protector 1 and is used to accelerate the airflow inside the housing 211.

[0029] The fan 223 is model DF8015B. The fan 223 draws external air into the top square box 221 through the rectangular holes of the grid plate 222, and filters it through the filter plate 229 before entering the housing 211. This cools the main body of the torque overload one-way protector 1 and prevents the friction plate from overheating and damaging the inside of the torque overload one-way protector 1.

[0030] In this embodiment, a slot 228 is provided inside the top square box 221, and a filter plate 229 is slidably inserted into the slot 228 to prevent dust from entering the interior of the housing 211.

[0031] The filter plate 229 is installed by sliding inside the slot 228, thereby preventing dust from entering the interior of the housing 211.

[0032] In this embodiment, the top square box 221 has an installation groove 224 inside, and an insertion post 225 is slidably installed inside the installation groove 224. A limit ring 227 is fixedly installed on the surface of the insertion post 225, and a spring 226 is sleeved on the surface of the insertion post 225. The top of the filter plate 229 is provided with an insertion hole 2210, and the bottom end of the insertion post 225 is slidably inserted into the interior of the insertion hole 2210.

[0033] The user pulls the insert 225 to remove it from the socket 2210, causing the filter plate 229 to move out of the slot 228. Then, the user pulls the insert 225 to insert the new filter plate 229 into the slot 228. The spring 226 pushes the insert 225 with its own elasticity to move it into the socket 2210, thus fixing the filter plate 229 and completing the replacement of the filter plate 229.

[0034] In this embodiment, a bottom square box 231 is fixedly installed at the bottom of the housing 211, a bent pipe 232 is fixedly installed at the bottom of the bottom square box 231, an exhaust box 233 is fixedly installed at the bottom of the bottom square box 231, and an exhaust pipe 234 is fixedly installed at the right end of the exhaust box 233 for dissipating heat from inside the housing 211. A rotating column 235 is rotatably installed inside the exhaust box 233, and several bent plates 236 are fixedly installed on the surface of the rotating column 235. A motor 237 is fixedly installed at the bottom of the exhaust box 233, and the output end of the motor 237 passes through the exhaust box 233 and is fixedly connected to the rotating column 235.

[0035] The motor 237 is model OMV800. It is electrically connected to an external power source and can be turned on and off via a human-operated control panel. When the motor 237 runs, it drives the rotating column 235 and the bending plate 236 to rotate. The rotation of the bending plate 236 quickly draws out the air blown into the housing 211 through the bending pipe 232 and discharges it through the exhaust pipe 234.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, firstly, the fan 223 draws external air into the top square box 221 through the rectangular holes of the grid plate 222, and then filters it through the filter plate 229 before entering the housing 211 to cool the main body of the torque overload unidirectional protector 1.

[0038] Then, the motor 237 drives the rotating column 235 and the bending plate 236 to rotate. The bending plate 236 rotates and quickly sucks out the air blown into the housing 211 through the bending pipe 232, and discharges it through the exhaust pipe 234.

[0039] Finally, the user pulls the insert 225 to remove it from the socket 2210, causing the filter plate 229 to move out of the slot 228. Then, the user pulls the insert 225 to insert the new filter plate 229 into the slot 228. The spring 226 pushes the insert 225 with its own elasticity, causing it to insert into the socket 2210 and fix the filter plate 229, thus completing the replacement of the filter plate 229.
