[0026] By providing a ring main unit with efficient heat dissipation in the embodiments of the present application, the problems that the ring main unit is deformed or damaged and cannot be replaced in time, and when replacing, it is necessary to first disconnect the connection with other ring main units before a new ring main unit can be replaced, the replacement process is time-consuming and laborious, and the replacement will damage the cabinet body, affecting the strength of the cabinet body and subsequent maintenance, and after the replacement, it is necessary to re-reinforce, during which the ring main unit cannot be used normally, affecting efficiency are solved.

[0027] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0028] The embodiments of the present utility model disclose a ring main unit with efficient heat dissipation.

[0029] According to the appendix Figure 1-6As shown in the figure, it includes multiple cabinets 1 spliced together. Multiple groups of cabinets 1 are used in combination. A quick disassembly mechanism 2 is arranged inside the cabinet 1. The quick disassembly mechanism 2 penetrates through the side wall of the cabinet 1. The quick disassembly mechanism 2 includes a fixed block 201, a threaded fixing strip 202, a handle 203 and a fixed clamping block 204;

[0030] When the device is in use, open the cabinet 1, grasp the fixed clamping block 204 in the quick disassembly mechanism 2 and rotate it to make it withdraw from the inside of the first fixed block 205 to release the lock. Lift the handle 203. The handle 203 drives the threaded fixing strip 202 to move, so that it withdraws from the inside of the fixed block 201. Remove the cabinet 1 that needs to be replaced and replace it with a new one. Press down the handle 203 to drive the threaded fixing strip 202 to snap into the inside of the fixed block 201. Grasp the fixed clamping block 204 and push it down to make it snap into the fixing hole inside the first fixed block 205 to complete the fixation. At the same time, for the side wall of the cabinet 1 that does not need to be installed, insert the plug block 4 into the side wall to prevent dust from entering the cabinet 1 and affecting the service life of the equipment inside the cabinet 1. If it is needed to be used, grasp the pull rope 5 and pull the plug block 4 to make it available for use. The heat dissipation mechanism 3 installed between the cabinets 1 has a guiding plate 302 installed inside the exhaust duct 301. The exhaust fan 303 starts to suck out the hot air inside the cabinet 1 and blows it out of the cabinet 1 through the exhaust duct 301 to complete heat dissipation. If the exhaust air outlets of the two exhaust fans 303 are directly discharged without the guiding plate 302, there will be an interaction between the two airflows, affecting the rotation efficiency of the exhaust fan 303 and further affecting the heat dissipation efficiency of the entire heat dissipation mechanism 3. The installed exhaust fan 303 can block the air flow and guide the air flow without affecting the use effect. At the same time, the top plate 304 arranged below the exhaust fan 303 can play a supporting role, and the support bars 305 at the bottom of the top plate 304 can increase the supporting effect of the top plate 304.

[0031] The threaded fixing strip 202 is movably inserted into the inside of the fixed block 201. The handle 203 is arranged in the middle of the threaded fixing strip 202. The handle 203 is fixedly connected to the threaded fixing strip 202. The fixed clamping block 204 is rotatably connected to the handle 203.

[0032] A first fixed block 205 is fixedly installed on one side inside the cabinet 1, and a second fixed block 206 is fixedly installed on the other side. A positioning block 207 is fixedly installed on the top of the first fixed block 205. One end of the handle 203 is rotatably connected inside the positioning block 207. The fixed block 201 is fixedly installed on the top of the second fixed block 206.

[0033] A fixing hole is opened on one side of the first fixed block 205. The fixed clamping block 204 is movably clamped with the fixing hole.

[0034] A fixed clamping strip 208 is rotatably connected inside the handle 203. The fixed clamping strip 208 is fixedly connected to the threaded fixing strip 202.

[0035] On one side of the cabinet body 1, a heat dissipation mechanism 3 is fixedly installed. The heat dissipation mechanism 3 includes an exhaust duct 301, a guiding plate 302, and an exhaust fan 303;

[0036] The exhaust duct 301 is fixedly installed on the back of the cabinet body 1. Ventilation openings are formed on both sides of the exhaust duct 301. The exhaust fan 303 is fixedly installed inside the ventilation openings on both sides of the exhaust duct 301.

[0037] The heat dissipation mechanism 3 further includes a top plate 304 and a support bar 305;

[0038] The top plate 304 is fixedly installed on one side inside the cabinet body 1. The top of the top plate 304 abuts against the bottom of the exhaust fan 303. One end of the support bar 305 is fixedly connected to the bottom of the top plate 304, and the other end is fixedly connected to the inner side wall of the cabinet body 1. The top plate 304 provides support for the exhaust fan 303, and the support bar 305 improves the support capacity of the top plate 304.

[0039] A plug block 4 is movably inserted into one side of the inner side wall of the cabinet body 1. A pull rope 5 is fixedly connected to the bottom of the plug block 4. The other end of the pull rope 5 is fixedly connected to the inner side wall of the cabinet body 1. When connection is needed, the pull rope 5 is pulled to take out the plug block 4 from the inside of the cabinet body 1. When connection is not needed, the plug block 4 is pushed into the cabinet body 1 to prevent dust from entering the inside of the cabinet body 1.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
