Description

Technical Field

[0001] This application relates to the field of ring main unit enclosures, and in particular to a modular intelligent ring main unit enclosure. Background Art

[0002] A modular intelligent ring main unit enclosure is a power equipment that designs each functional part of the ring main unit enclosure into relatively independent modules. These modules can be flexibly combined and expanded according to actual needs, and at the same time have intelligent monitoring, control, and management functions.

[0003] During the operation of the modular intelligent ring main unit enclosure, since multiple functional modules are integrated in the inner cavity of the enclosure, part of the electric energy is converted into heat energy during the operation of the multiple functional modules, causing the temperature in the inner cavity of the enclosure to rise, and making the multiple functional modules operate in a high-temperature state for a long time and wear out, thereby reducing the service life of the modular intelligent ring main unit enclosure. Summary of the Invention

[0004] In order to improve the problem that multiple functional modules are worn out during long-term operation in a high-temperature state, this application provides a modular intelligent ring main unit enclosure.

[0005] A modular intelligent ring main unit enclosure provided by this application adopts the following technical solution: A modular intelligent ring main unit enclosure includes a box body and a plurality of heat dissipation devices. A plurality of installation cavities for installing functional modules are spaced apart on the surface of the box body. The inner walls of the installation cavities are rotatably connected with box doors, and the box doors can cover the installation cavities. The heat dissipation devices are in one-to-one correspondence with the box doors and are connected to the surfaces of the box doors facing the installation cavities. The heat dissipation device includes a heat dissipation fan, a plurality of check valves I, and a plurality of check valves II. The heat dissipation fan is connected to the surface of the box door facing the installation cavity, and the air outlet end of the heat dissipation fan faces the functional module in the installation cavity. A plurality of air inlet holes are spaced apart on the end face of the box door facing the air inlet end of the heat dissipation fan. The check valves I are in one-to-one correspondence with the air inlet holes and are connected to the inner walls of the air inlet holes. The check valves I allow external air to enter the installation cavity through the air inlet holes. A plurality of air outlet holes are spaced apart on the inner wall of the installation cavity. The air outlet holes penetrate through the outer wall of the box body. The check valves II are in one-to-one correspondence with the air outlet holes and are connected to the inner walls of the air outlet holes. The check valves II allow the air in the installation cavity to be discharged from the air outlet holes.

[0006] By adopting the above technical solution, the functional modules are installed on the inner wall of the installation cavity one by one. When the modular intelligent ring main distribution box is started, the functional modules convert part of the electric energy into heat energy. The air in the installation cavity is in full contact with the functional modules and undergoes heat exchange to cool down the functional modules. At the same time, the air temperature in the installation cavity continuously rises, and the cooling fan operates. The cooling fan drives the outside air to enter the installation cavity through the one-way valve one from the air inlet holes and impacts the functional modules, enabling the functional modules to be in full contact with the air and undergo heat exchange, improving the cooling of the functional modules. At the same time, the air pressure in the installation cavity continuously rises, and the air in the installation cavity is discharged from the air outlet holes through the one-way valve two, realizing the pressure reduction in the inner cavity of the installation cavity, promoting the air flow in the installation cavity, and preventing the multiple functional modules from operating at a high temperature during operation and being damaged, thereby prolonging the service life of the modular intelligent ring main distribution box.

[0007] Optionally, the one-way valve one is slidably connected to the inner wall of the air inlet hole. The heat dissipation device further includes a cleaning component, and the cleaning component includes a cleaning plate, a plurality of cleaning pistons, and a plurality of connecting bars. A cleaning cavity for the cleaning plate to slide is provided on the surface of the box door facing the air inlet end of the cooling fan. The sliding direction of the cleaning plate and the sliding direction of the one-way valve one are parallel to each other. The cleaning cavity communicates with a plurality of air inlet holes. A plurality of connecting holes are spaced apart on the surface of the cleaning plate. The connecting holes communicate the air inlet holes and the installation cavity. The plurality of cleaning pistons are spaced apart and connected to the surface of the cleaning plate facing the air inlet holes. The cleaning pistons correspond to the air inlet holes one by one, and the end of the cleaning piston can be embedded into the inner cavity of the air inlet hole. The connecting bars correspond to the cleaning pistons one by one. One end of the connecting bar is connected to the end face of the cleaning piston, and the other end of the connecting bar is connected to the surface of the one-way valve one. When the cleaning plate moves close to the air inlet holes along the inner wall of the cleaning cavity, it drives the end of the cleaning piston to be embedded into the air inlet holes. The connecting bar receives the power of the cleaning piston and drives the one-way valve one to slide in a direction away from the box door. The outer peripheral surface of the one-way valve one abuts against the inner wall of the air inlet hole and scrapes the impurities on the inner wall of the air inlet hole.

[0008] By adopting the above technical solution, when it is necessary to clean the inner wall of the air inlet holes, the cleaning plate is driven to slide along the inner wall of the cleaning cavity in a direction close to the air inlet holes. The cleaning pistons correspond to the air inlet holes one by one, and the end of the cleaning piston is embedded into the air inlet holes. The connecting bar receives the power of the cleaning piston and drives the one-way valve one to slide along the inner wall of the air inlet hole in a direction away from the box door. The outer peripheral surface of the one-way valve one abuts against the inner wall of the air inlet hole and drives the impurities on the inner wall of the air inlet hole to break away from the air inlet holes, realizing the synchronous cleaning of the inner walls of a plurality of air inlet holes, without the need for staff to clean the inner walls of the air inlet holes one by one, thereby improving the cleaning efficiency of the modular intelligent ring main distribution box.

[0009] Optionally, the heat dissipation device further includes a starting component, which includes a thermal expansion and contraction strip. One end of the thermal expansion and contraction strip is connected to the inner wall of the cleaning cavity near the air inlet hole, and the other end of the thermal expansion and contraction strip is connected to the surface of the cleaning plate. The end of the cleaning piston is embedded in the air inlet hole to close the air inlet hole. When the thermal expansion and contraction strip heats up and expands, and drives the cleaning plate to approach the installation cavity along the inner wall of the cleaning cavity, the end of the cleaning piston disengages from the air inlet hole, and the closing effect of the cleaning piston on the air inlet hole disappears.

[0010] By adopting the above technical solution, one end of the thermal expansion and contraction strip is connected to the inner wall of the cleaning cavity near the air inlet hole, the other end of the thermal expansion and contraction strip is connected to the surface of the cleaning plate, the end of the cleaning piston is embedded in the air inlet hole to close the air inlet hole. When the thermal expansion and contraction strip heats up and expands, and drives the cleaning plate to slide along the inner wall of the cleaning cavity towards the installation cavity, it drives the end of the cleaning piston to disengage from the air inlet hole, and the closing effect of the cleaning piston on the air inlet hole disappears. The outside air passes through the one-way valve one in sequence through the air inlet hole, the cleaning cavity and the connection hole and enters the installation cavity, realizing the directional start of the air inlet hole. There is no need for staff to manually drive the cleaning plate to slide, thereby improving the simplicity of using the modular intelligent ring main unit box.

[0011] Optionally, the starting component further includes a first contact switch, which is connected to the inner wall of the cleaning cavity near the installation cavity. The cooling fan is electrically connected to the first contact switch. When the thermal expansion and contraction strip heats up and expands, and drives the cleaning plate to approach the first contact switch along the inner wall of the cleaning cavity, the first contact switch abuts against the surface of the cleaning plate and conducts, and the cooling fan gets power and runs.

[0012] By adopting the above technical solution, when the thermal expansion and contraction strip heats up and expands, and drives the cleaning plate to slide along the inner wall of the cleaning cavity towards the first contact switch, the first contact switch abuts against the surface of the cleaning plate and conducts, and the cooling fan gets power and runs, realizing the directional start of the cooling fan. The cooling fan does not need to keep running all the time, reducing energy consumption, thereby reflecting the concept of energy saving.

[0013] Optionally, the heat dissipation device further includes a filtering component, which includes a filter cover and a water-absorbing expansion plate. The filter cover is connected to the surface of the box door facing the installation cavity. The inner cavity of the filter cover covers the cooling fan. The water-absorbing expansion plate is connected to the inner cavity wall of the filter cover. The water-absorbing expansion plate can adsorb the moisture in the air. A plurality of filter holes are spaced apart on the inner wall of the filter cover facing the water-absorbing expansion plate. The filter holes communicate the inner cavity of the filter cover and the installation cavity. The cooling fan drives the air in the filter cover to pass through the water-absorbing expansion plate for filtering and then enter the installation cavity through the filter holes.

[0014] By adopting the above technical solution, the inner cavity of the filter cover covers the cooling fan. When the cooling fan operates, it pushes the outside air to pass through the one-way valve one and sequentially passes through the air inlet holes, the cleaning cavity, the connection holes, the inner cavity of the filter cover, the water-absorbing expansion plate and enters the installation cavity through the filter holes to impact the surface of the functional module. The water-absorbing expansion plate absorbs the moisture in the air, ensuring the control of the air humidity in the installation cavity, so that the functional module in the installation cavity is not easily damaged by moisture corrosion, thereby extending the service life of the modular intelligent ring network box.

[0015] Optionally, the filter assembly further includes a warning rod and a first elastic member. A warning cavity for the warning rod to slide is formed on the surface of the box door. The warning cavity communicates with the inner cavity of the filter cover. One end of the first elastic member in the direction of its elastic force is connected to the surface of the box door, and the other end of the first elastic member in the direction of its elastic force is connected to the rod surface of the warning rod. The first elastic member has an elastic force to drive one end of the warning rod to abut against the plate surface of the water-absorbing expansion plate, and the other end of the warning rod is flush with the surface of the box door.

[0016] By adopting the above technical solution, the first elastic member has an elastic force to drive one end of the warning rod to abut against the plate surface of the water-absorbing expansion plate, and the other end of the warning rod is flush with the surface of the box door. When the water-absorbing expansion plate absorbs the moisture in the air, the water-absorbing expansion plate absorbs water and expands. The water-absorbing expansion plate drives the warning rod to overcome the elastic force of the first elastic member and slide away from the box door. The end of the warning rod protrudes from the surface of the box door. The staff can judge the water absorption situation of the water-absorbing expansion plate according to the distance that the end of the warning rod protrudes from the box door, so as to facilitate the staff to replace the water-absorbing expansion plate in time and further improve the simplicity of using the modular intelligent ring network box.

[0017] Optionally, the filter assembly further includes a closing plate and a second elastic member. A closing cavity for the closing plate to slide is formed on the surface of the box door facing away from the installation cavity. The closing cavity communicates with the warning cavity and a plurality of air inlet holes. One end of the second elastic member in the direction of its elastic force is connected to the plate surface of the closing plate, and the other end of the second elastic member in the direction of its elastic force is connected to the inner wall of the closing cavity. The second elastic member has an elastic force to drive the closing plate to slide towards the air inlet holes, and the plate surface of the closing plate abuts against the rod surface of the warning rod to form a limiting trend. A closing groove for the closing plate to pass through is formed on the rod surface of the warning rod. When the water-absorbing expansion plate absorbs water and expands and drives the warning rod away from the box door, the closing groove communicates with the closing cavity. The elastic force of the second elastic member drives the closing plate to pass through the closing groove and slide towards the air inlet holes, and the plate surface of the closing plate abuts against the inner wall of the closing cavity to close the air inlet holes.

[0018] By adopting the above technical solution, when the water-absorbing and swelling plate continuously absorbs water and swells, it drives the warning rod to slide along the inner wall of the warning cavity in a direction away from the box door. The closing groove communicates with the closing cavity, and the elastic force of the second elastic member drives the closing plate to penetrate the closing groove along the inner wall of the closing cavity and continue to slide in a direction closer to the air inlet hole. The surface of the closing plate abuts against the inner wall of the closing cavity and closes the air inlet hole, making it difficult for external air to continue entering the installation cavity through the air inlet hole, realizing precise control of the humidity of the air in the installation cavity. At the same time, the surface of the closing plate abuts against the inner wall of the closing cavity and scrapes the impurities on the inner wall of the closing cavity, realizing directional cleaning of the impurities on the inner wall of the closing cavity.

[0019] Optionally, a guiding surface is provided at the end of the closing plate facing the warning rod. The guiding surface is in the shape of an arc convex, and the guiding surface guides the closing plate to penetrate the closing groove.

[0020] By adopting the above technical solution, when the warning rod slides along the inner wall of the warning cavity in a direction away from the box door, the closing groove communicates with the closing cavity, and the elastic force of the second elastic member drives the closing plate to slide along the inner wall of the closing cavity in a direction closer to the air inlet hole. The guiding surface guides the closing plate to penetrate the closing groove, reducing the wear between the closing plate and the warning rod, thereby prolonging the service life of the modular intelligent ring network box.

[0021] Optionally, the filtering component further includes a second contact switch and a warning horn. The warning horn is connected to the surface of the box door, the second contact switch is connected to the inner wall of the closing cavity close to the air inlet hole, and the second contact switch is electrically connected to the warning horn. When the surface of the closing plate abuts against the inner wall of the closing cavity and closes the air inlet hole, the second contact switch abuts against the surface of the closing plate and conducts, and the warning horn is powered on and emits a sound.

[0022] By adopting the above technical solution, when the elastic force of the second elastic member drives the closing plate to penetrate the warning groove and continue to approach the air inlet hole, the surface of the closing plate abuts against the closing cavity and closes the air inlet hole. The second contact switch abuts against the surface of the closing plate and conducts, and the warning horn is powered on and emits a sound, thereby warning the staff to replace the water-absorbing and swelling plate in time, so as to ensure the stability of the operation of the modular intelligent ring network box.

[0023] Optionally, the filter cover is fixed on the surface of the box door by bolts.

[0024] By adopting the above technical solution, the filter cover and the box door are detachably connected by bolts, which is convenient for replacing the water-absorbing and swelling plate, thereby improving the simplicity of using the modular intelligent ring network box.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the cooling fan, the first one-way valve and the second one-way valve promotes the air flow in the installation cavity, so that the multiple functional modules are not easily operated at a high temperature during operation and are damaged, thereby prolonging the service life of the modular intelligent ring network box; 2.

The check valves two 26 allow the air in the installation cavity 11 to be discharged through the air outlet holes 12, realizing the one-way flow of air in the air inlet holes 31, and at the same time promoting the air flow in the installation cavity 11, making the air in full contact with the functional modules and heat exchange occur, realizing the cooling of the functional modules, thereby improving the cooling efficiency of the modular intelligent ring network box.

[0035] Refer to Figure 1 and Figure 2, the one-way valve 25 slides along the axis of the air inlet hole 31 on the inner wall of the air inlet hole 31. The cleaning assembly 22 is connected between the box door 3 and the one-way valve 25. The cleaning assembly 22 can push the one-way valve 25 to slide on the inner wall of the air inlet hole 31, and drive the impurities on the inner wall of the air inlet hole 31 to break away from the inner wall of the air inlet hole 31. The cleaning assembly 22 includes a cleaning plate 221, a plurality of cleaning pistons 222 and a plurality of connecting bars 223.

In the embodiment of the present application, the first elastic member 244 is a compression spring and has a certain deformation ability. One end in the direction of the elastic force of the first elastic member 244 is connected to the surface of the cabinet door 3, and the other end in the direction of the elastic force of the first elastic member 244 is connected to the rod surface of the warning rod 243. The first elastic member 244 has an elastic force to drive the warning rod 243 to slide in the direction close to the water-absorbing and swelling plate 242. One end of the warning rod 243 abuts against the plate surface of the water-absorbing and swelling plate 242, and the other end of the warning rod 243 has a tendency to be flush with the surface of the cabinet door 3.

[0042] Refer to Figure 1 and Figure 2 , when the water-absorbing and swelling plate 242 continuously absorbs the moisture in the air and expands, the water-absorbing and swelling plate 242 drives the warning rod 243 to overcome the elastic force of the first elastic member 244 and slide in the direction away from the cabinet door 3. The distance that the end of the warning rod 243 protrudes from the cabinet door 3 is the expansion distance of the water-absorbing and swelling plate 242, so that the staff can directly observe the expansion multiple of the water-absorbing and swelling plate 242, thus facilitating the staff to replace the water-absorbing and swelling plate 242 in time.

[0043] Refer to Figure 1 and Figure 2, a closing cavity 34 for the sliding of the closing plate 245 is formed on the surface of the cabinet door 3 facing away from the installation cavity 11. The sliding direction of the closing plate 245 is parallel to the height direction of the cabinet door 3. The warning cavity 33 and the plurality of air inlet holes 31 are both communicated with the closing cavity 34. The second elastic member 246 can be a compression spring or a tension spring. In the embodiment of the present application, the second elastic member 246 is a compression spring and has a certain deformation ability. One end of the second elastic member 246 in the direction of the elastic force is connected to the inner wall of the closing cavity 34, and the other end of the second elastic member 246 in the direction of the elastic force is connected to the plate surface of the closing plate 245. The second elastic member 246 has an elastic force to drive the closing plate 245 to slide towards the direction close to the air inlet hole 31, and there is a tendency for the plate surface of the closing plate 245 to abut against the rod surface of the warning rod 243.

[0044] Refer to Figure 2 and Figure 4 , a closing groove 2431 for the closing plate 245 to pass through is formed on the rod surface of the warning rod 243. A guiding surface 2451 is provided on the end surface of the closing plate 245 in contact with the warning rod 243. The guiding surface 2451 is in a circular arc convex shape. The guiding surface 2451 can abut against the inner wall of the closing groove 2431 and guide the closing plate 245 to pass through the closing groove 2431, reducing the wear between the closing plate 245 and the warning rod 243, thereby prolonging the service life of the modular intelligent ring network cabinet; the warning horn 248 is fixed on the surface of the cabinet door 3 by bolts. The second contact switch 247 is connected to the inner wall of the closing cavity 34 close to the air inlet hole 31. The second contact switch 247 is electrically connected to the warning horn 248; when the water absorption expansion plate 242 absorbs water and expands, the water absorption expansion plate 242 drives the warning rod 243 to slide along the inner wall of the warning cavity 33 away from the cabinet door 3. The closing groove 2431 communicates with the closing cavity 34. The elastic force of the second elastic member 246 drives the end of the closing plate 245 to pass through the closing groove 2431 and continue to slide towards the direction close to the air inlet hole 31. The plate surface of the closing plate 245 abuts against the inner wall of the closing cavity 34 and scrapes the impurities on the inner wall of the closing cavity 34. At the same time, the plate surface of the closing plate 245 abuts against the inner wall of the closing cavity 34 and closes the air inlet hole 31, realizing the directional start of the air inlet hole 31. At the same time, the second contact switch 247 abuts against the plate surface of the closing plate 245 and is turned on, and the warning horn 248 is powered on and emits a sound, thereby warning the staff to replace the water absorption expansion plate 242 in time, realizing the directional replacement of the water absorption expansion plate 242, and thus improving the simplicity of using the modular intelligent ring network cabinet.

[0045] The implementation principle of a modular intelligent ring main cabinet in an embodiment of the present application is as follows: When the modular intelligent ring main cabinet is in use, the thermal expansion and contraction strip 231 expands upon heating. The thermal expansion and contraction strip 231 drives the cleaning plate 221 to slide along the inner wall of the cleaning cavity 32 towards the direction close to the contact switch one 232. The end of the cleaning piston 222 disengages from the air inlet hole 31, and the sealing effect of the cleaning piston 222 on the air inlet hole 31 disappears. At the same time, the contact switch one 232 abuts against the thermal expansion and contraction strip 231 and conducts, and the contact switch one 232 abuts against the cleaning plate 221 and conducts. The cooling fan 21 is powered on and operates, driving the outside air to pass through the one-way valve one 25 in sequence through the air inlet hole 31, the cleaning cavity 32, the connection hole 2211, the inner cavity of the filter cover 241, and after being filtered by the water-absorbing expansion plate 242, enters the installation cavity 11 through the filter holes 2411 and impacts the surface of the functional module. The functional module is in full contact with the air and conducts heat exchange, realizing the cooling of the functional module. At the same time, the water-absorbing expansion plate 242 can adsorb the moisture in the air, realizing the drying of the air. When the air pressure in the installation cavity 11 continuously rises, the air in the installation cavity 11 is discharged from the air outlet hole 12 through the one-way valve two 26, promoting the air flow in the installation cavity 11, so that the multiple functional modules are not easily operated at a high temperature during operation and are not damaged, thereby prolonging the service life of the modular intelligent ring main cabinet.

[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
