Description
Technical Field
[0001] The utility model belongs to the technical field of electric meter boxes, and particularly relates to an outdoor heat dissipation type electric meter box. Background Technique
[0002] In an outdoor environment, the electric meter box needs to have good heat dissipation performance to ensure the normal operation of internal electronic devices. Under high temperature, humidity, and even harsh weather conditions, the design of the electric meter box must be able to effectively dissipate the heat generated inside, while protecting the internal devices from the environmental impact. Considering the stability, safety of electronic devices and the requirements for long-term outdoor use, designing an outdoor heat dissipation type electric meter box becomes a challenging and practical task.
[0003] In the existing electric meter box, heat dissipation fins or heat dissipation windows are arranged on the outer shell surface to increase the heat dissipation surface area and promote heat transfer to the external environment. At the same time, a plurality of ventilation holes are arranged on the electric meter box to utilize natural convection or an auxiliary fan to circulate air and accelerate heat dissipation. In addition, an internal or external heat dissipation fan is provided to increase the heat dissipation effect by natural convection or an active fan to circulate air.
[0004] However, in the actual use process, a certain amount of dust and impurities will be carried into the electric meter box during ventilation. The dust entering the inside of the electric meter box may cover the surface of electronic components, resulting in poor heat dissipation of the electronic components, increasing the working temperature of the electronic devices, thereby increasing the failure rate of the electronic devices. At the same time, the accumulation of dust may cause corrosion or damage to the surface of the electronic devices, further shortening the service life of the devices, increasing the maintenance and replacement costs. At the same time, the cleaning and replacement of the dust filter of the device are also relatively cumbersome and require manual handling.
[0005] Therefore, the utility model provides an outdoor heat dissipation type electric meter box. Content of the Utility Model
[0006] In order to make up for the deficiencies of the existing technology and solve the problems of inconvenient replacement and cleaning of the filter screen, the utility model provides an outdoor heat dissipation type electric meter box.
[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: An outdoor heat-dissipating electric meter box of the present utility model includes a main cabinet. Three cabinet doors are rotatably connected to the front end of the main cabinet. An installation groove is opened at the bottom right end of the main cabinet. A first dust-proof net is slidably connected to the inner side of the installation groove. A protective cover is rotatably connected to the outside of the rear end of the inner side of the installation groove. A clamping rod is slidably connected to the inner front end of the protective cover. A spring is arranged on the outer side of the bottom end of the clamping rod. A handle is fixedly connected to the outer wall of the rear side of the clamping rod. The clamping rod is clamped and connected to the top end of the installation groove. A second mounting rack is fixedly connected to the left end inside the main cabinet. A clamping assembly is arranged at the top of the left end inside the main cabinet. A heat-dissipating assembly is arranged inside the clamping assembly. A second dust-proof net is arranged inside the clamping assembly;
[0008] Through the above technical solution, by pulling down the handle to drive the clamping rod to move downward, the clamping and fixing of the protective cover by the main cabinet can be cancelled, the protective cover can be opened, and the first dust-proof net can be taken out, realizing the quick disassembly of the first dust-proof net.
[0009] Further, the clamping assembly includes a stop block. A first mounting rack is fixedly connected to the top of the left end inside the main cabinet. A clamping block is rotatably connected to the outer side of the top end of the first mounting rack. The first mounting rack is slidably connected to the second dust-proof net. Stop blocks that are opposite to each other front and back are fixedly connected to the outer side of the bottom end of the first mounting rack. The stop blocks are clamped and connected to the bottom end of the second dust-proof net. The clamping block is clamped and connected to the top end of the second dust-proof net;
[0010] Through the above technical solution, the second dust-proof net can be quickly removed by rotating the clamping block, and the dust outside the clamping block can be cleaned by blowing air outward through the heat-dissipating assembly. Thus, after the first dust-proof net is severely blocked, it can be replaced with the second dust-proof net, thereby reducing the cleaning cost.
[0011] Further, the heat-dissipating assembly includes a connecting pipe. A heat-dissipating box is fixedly connected to the inside of the first mounting rack. A communication hole is opened in the heat-dissipating box. Ventilation holes are evenly distributed on the outer wall of the heat-dissipating box. A connecting pipe is fixedly connected to the front side of the top end of the heat-dissipating box. A delivery pump is fixedly connected to the bottom end of the connecting pipe. A water outlet pipe is fixedly connected to the bottom end of the delivery pump. A cooling plate is fixedly connected to the bottom end of the water outlet pipe. An inlet pipe is fixedly connected to the bottom right end of the cooling plate. The front side of the top end of the inlet pipe is fixedly connected to the bottom rear end of the heat-dissipating box. An exhaust fan is fixedly connected to the inside of the heat-dissipating box. The cooling plate is fixedly connected to the second mounting rack;
[0012] Through the above technical solution, a coolant pump uses a connecting pipe, a communication hole, a water inlet pipe, a cooling plate, and a water outlet pipe to circulate the coolant. At the same time, an exhaust fan discharges the internal air outward. During the discharge process, the temperature carried by the heated coolant in the communication hole is transferred to the inner wall of the ventilation hole, and heat exchange is performed with the air flowing inside the ventilation hole, thereby cooling the coolant and achieving the circulating cooling of the cooling plate.
[0013] Further, a liquid replenishing bottle is fixedly connected to the right end of the rear side of the heat dissipation box;
[0014] Through the above technical solution, a piston is provided at the top end inside the liquid replenishing bottle, a spring is provided at the top end of the piston, and at the same time, a ventilation hole is opened at the top end of the liquid replenishing bottle to communicate with the outside. When the coolant in the heat dissipation box expands and contracts due to temperature, the internal pressure can be adjusted through the liquid replenishing bottle.
[0015] Further, a heat insulation cover plate is fixedly connected to the top end of the main cabinet;
[0016] Through the above technical solution, the sunlight irradiation is blocked by the heat insulation cover plate to prevent the temperature inside the main cabinet from being too high due to sunlight irradiation in summer.
[0017] Further, the installation surfaces of the second dust-proof net and the first dust-proof net are the same;
[0018] Through the above technical solution, when replacing the first dust-proof net and the second dust-proof net, it is necessary to install the side with the dust attached to the first dust-proof net outward into the first mounting rack, and the first dust-proof net is cleaned when the exhaust fan discharges air outward.
[0019] The beneficial effects of the present utility model are as follows:
[0020] 1. For an outdoor heat dissipation type electric meter box of the present utility model, the air entering the main cabinet is filtered by the first dust-proof net, and the dust is filtered out to prevent the dust from affecting the internal equipment. At the same time, the first dust-proof net and the second dust-proof net are quickly replaced, and at the same time, the exhaust fan discharges air outward, thereby cleaning the replaced filter screen, which is convenient for use.
[0021] 2. For an outdoor heat dissipation type electric meter box of the present utility model, the internal air is discharged outward by the exhaust fan, thereby reducing the influence of the heat emitted by the internal equipment on the equipment itself. At the same time, during the exhaust process of the exhaust fan, the heat transferred by the coolant in the communication hole in the ventilation hole is discharged together with the discharged air, thereby realizing liquid cooling and temperature reduction. And the equipment installed in the main cabinet is directly cooled by the cooling plate in the heat dissipation component, thereby improving the cooling effect. Description of the Drawings

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0035] Embodiment 1:
[0036] Such as Figures 1 to 10As shown in the figure, an outdoor heat-dissipating electric meter box of the present utility model includes a main cabinet 1. Three cabinet doors 11 are rotatably connected to the front end of the main cabinet 1. The three cabinet doors 11 are limited by the main cabinet 1 at the same time. An installation groove 2 is opened at the bottom right end of the main cabinet 1. A first dust-proof net 21 is slidably connected inside the installation groove 2. The first dust-proof net 21 is limited by the installation groove 2. A protective cover 22 is rotatably connected to the outside of the rear end inside the installation groove 2. The protective cover 22 is limited by the installation groove 2. A clamping rod 23 is slidably connected to the inside of the front end of the protective cover 22. The clamping rod 23 is limited by the protective cover 22. A spring 25 is arranged on the outside of the bottom end of the clamping rod 23. The spring 25 is limited by the clamping rod 23. A handle 24 is fixedly connected to the outer wall of the rear side of the clamping rod 23. The handle 24 is fixed by the clamping rod 23. The clamping rod 23 is clamped and connected to the top end of the installation groove 2. The clamping rod 23 is clamped by the installation groove 2. Thus, the clamping rod 23 is pushed upward by the spring 25 with the bottom end of the groove on the outside of the spring 25 as the stress point. At the same time, the clamping rod 23 is limited by the installation groove 2, so as to fix the protective cover 22. Because the first dust-proof net 21 is arranged below, the protective cover 22 is set to fix the first dust-proof net 21 and protect the first dust-proof net 21 at the same time, avoiding damage to the first dust-proof net 21 caused by external force. A second mounting bracket 4 is fixedly connected to the left end inside the main cabinet 1. The second mounting bracket 4 is fixed by the main cabinet 1. A clamping component is arranged at the top of the left end inside the main cabinet 1. A heat-dissipating component is arranged inside the clamping component. A second dust-proof net 27 is arranged inside the clamping component.
[0037] The clamping component includes a stop block 29. A first mounting bracket 26 is fixedly connected to the top of the left end inside the main cabinet 1. The first mounting bracket 26 is fixed by the main cabinet 1. A clamping block 28 is rotatably connected to the outside of the top end of the first mounting bracket 26. The clamping block 28 is limited by the top end of the first mounting bracket 26. The first mounting bracket 26 is slidably connected to the second dust-proof net 27. The second dust-proof net 27 is limited by the first mounting bracket 26. Two front and rear opposite stop blocks 29 are fixedly connected to the outside of the bottom end of the first mounting bracket 26. The stop block 29 is clamped and connected to the bottom end of the second dust-proof net 27. The stop block 29 is fixed by the bottom end of the first mounting bracket 26, so as to clamp and fix the bottom end of the second dust-proof net 27 and prevent the second dust-proof net 27 from moving outwards. The clamping block 28 is clamped and connected to the top end of the second dust-proof net 27. The top end of the second dust-proof net 27 is limited by the clamping block 28, so as to fix the top end of the second dust-proof net 27.
[0038] The heat dissipation component includes a connecting pipe 33. Inside the first mounting bracket 26, a heat dissipation box 3 is fixedly connected. The heat dissipation box 3 is fixed to the inner wall of the main cabinet 1 through the first mounting bracket 26. A communication hole 31 is opened inside the heat dissipation box 3, and ventilation holes 32 are evenly distributed on the outer wall of the heat dissipation box 3. The communication hole 31 is designed in an S shape, so as to increase the contact area between the coolant and the ventilation holes 32, and thus transfer more heat to the inner wall of the ventilation holes 32. At the front side of the top end of the heat dissipation box 3, a connecting pipe 33 is fixedly connected. At the bottom end of the connecting pipe 33, a delivery pump 34 is fixedly connected. The heat dissipation box 3 and the delivery pump 34 are connected through the connecting pipe 33. At the bottom end of the delivery pump 34, a water outlet pipe 35 is fixedly connected. At the bottom end of the water outlet pipe 35, a cooling plate 36 is fixedly connected. The cooling plate 36 is connected through the water outlet pipe 35. At the bottom right side of the cooling plate 36, a water inlet pipe 37 is fixedly connected. The front side of the top end of the water inlet pipe 37 is fixedly connected to the bottom rear side of the heat dissipation box 3. The cooling plate 36 and the heat dissipation box 3 are connected through the water inlet pipe 37 to form a closed loop. An exhaust fan 39 is fixedly connected inside the heat dissipation box 3. The exhaust fan 39 extracts and discharges the internal air outward, and at the same time discharges the heat transferred out of the ventilation holes 32 to realize the cooling of the coolant. The cooling plate 36 is fixedly connected to the second mounting bracket 4. The heat generated by the ammeter installed on the second mounting bracket 4 is absorbed through the cooling plate 36 and the coolant inside the cooling plate 36, so as to directly cool the equipment. And subsequently, more water outlet pipes 35, cooling plates 36 and water inlet pipes 37 can be connected in parallel according to needs for water-cooling cooling in a point-to-point manner.
[0039] At the right rear side of the heat dissipation box 3, a liquid replenishing bottle 38 is fixedly connected. The internal pressure of the heat dissipation box 3 is adjusted through the liquid replenishing bottle 38.
[0040] At the top end of the main cabinet 1, a heat insulation cover plate 12 is fixedly connected. The sunlight is blocked through the heat insulation cover plate 12 to reduce the temperature inside the main cabinet 1.
[0041] The second dust-proof net 27 has the same installation surface as the first dust-proof net 21. When replacing the dust-filtering side of the first dust-proof net 21 with the second dust-proof net 27, it is installed on the outer side facing outward inside the first mounting bracket 26. Thus, when exhausting air outward through the exhaust fan 39, the external dust can be cleaned by the air flow.
[0042] Working principle: When the outdoor heat-dissipating electric meter box is operating, first, the exhaust fan 39 discharges the air inside the main cabinet 1 to the outside, and air is supplemented inward through the first dust-proof net 21. At the same time, the first dust-proof net 21 filters the dust in the air. Then, the coolant in the communication hole 31 is pumped by the delivery pump 34 through the connecting pipe 33 and is transported into the cooling plate 36 through the water outlet pipe 35. The equipment installed on the second mounting bracket 4 is cooled by the cooling plate 36. After that, the heated coolant is re-transported back into the communication hole 31 through the water inlet pipe 37 for circulation. The coolant in the communication hole 31 transfers heat to the inner wall of the ventilation hole 32 and exchanges heat with the external air. At the same time, during the exhaust process by the exhaust fan 39, the heat inside the ventilation hole 32 is discharged together, thereby cooling the coolant. When replacing the first dust-proof net 21 and the second dust-proof net 27 with each other, only need to pull down the handle 24. The handle 24 drives the engaging rod 23 to move downward and compress the spring 25, canceling the engagement with the mounting groove 2, so that the protective cover 22 can be opened, and the first dust-proof net 21 can be quickly taken out. Then, by directly rotating the engaging block 28, the second dust-proof net 27 can be quickly taken out. After that, with the dust-filtering side of the first dust-proof net 21 facing outward, it is installed into the first mounting bracket 26, and the dust attached to the outer wall of the first dust-proof net 21 is cleaned by the gas discharged by the exhaust fan 39.

Taking the perspective of the person observing as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
