[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an electrical control box suitable for harsh environments provided by an embodiment of the present invention comprises a control box body 1 and a box door 2, a plurality of electrical components 3 are installed inside the control box body 1, a closing structure 4 is arranged on the control box body 1, the closing structure 4 comprises a plurality of fixing frames 5 fixedly installed on the side of the control box body 1, a rotating rod 6 is movably installed on the fixing frame 5, a plurality of connecting frames 7 are fixedly installed on the control box body 1, a toggle block 8 which fits the connecting frame 7 is fixedly installed on the rotating rod 6, an elastic pull ring 9 is movably installed on the toggle block 8, a plurality of fixing rings 10 are fixedly installed on the control box body 1, a groove 11 which cooperates with the elastic pull ring 9 is opened on the fixing ring 10, and a connecting frame 7 is fixedly installed on the fixing ring 10. 7 and the toggle block 8 are both provided with a first threaded hole 12, a first bolt 13 connected to the toggle block 8 is installed on the connecting frame 7, and a corrosion-resistant sealing strip 14 is fixedly installed on the control box body 1 and the box door 2. The surface of the control box body 1 is coated with an anti-corrosion paint coating 49. Through the setting of the closing structure 4, the traditional mechanical locking method of the box door 2 is changed, so that the box door 2 can still be conveniently opened in harsh environments such as high temperature, humidity, and corrosive gases, and the stability and durability will not be affected. When the control box body 1 needs to be sealed, the box door 2 is first pushed to make it fit on the control box body 1. At this time, the fixing ring 10 on the box door 2 will be in contact with the control box body 1. The corner of the box body 1 fits well, and then the first bolt 13 is removed from the inside of the first threaded hole 12, and then the toggle block 8 is pushed upward to make the elastic pull ring 9 approach the direction of the fixing ring 10, and then the elastic pull ring 9 is stuck into the groove 11 on the fixing ring 10, and then the toggle block 8 is pressed to make the elastic pull ring 9 have a downward pulling force, so that the box door 2 can be tightened to make it fit tightly on the control box body 1, thereby preventing the box door 2 from loosening, and finally screwing the first bolt 13 into the inside of the first threaded hole 12 to connect the connecting frame 7 and the toggle block 8 together, which can improve the stability of the toggle block 8 and prevent the toggle block 8 from loosening and causing the box door 2 to open. When the box door 2 is attached to the control box body 1, the corrosion-resistant sealing strip 14 on the control box body 1 can be attached to the corrosion-resistant sealing strip 14 on the box door 2, which can ensure that the control box body 1 and the box door 2 are tightly sealed and prevent corrosive gases and dust from entering. The anti-corrosion paint coating 49 applied on the surface of the control box body 1 can further improve its corrosion resistance. The advantage of this structure is that there is no need to manually use keys or other tools to open the box door 2, thereby avoiding increased operational complexity and time cost in certain emergency or complex environments. This structure will not be worn or damaged during long-term use, so there is no need for regular replacement and maintenance, thereby reducing maintenance costs and time.

[0034] like Figure 3As shown in the figure, an electrical control box applicable to harsh environments provided by an embodiment of the present invention. Inside the control box main body 1, a heat pipe radiator 15 is fixedly installed. On the top of the control box main body 1, heat dissipation fins 16 are fixedly installed. The heat dissipation fins 16 are connected to the control box main body 1 through a plurality of second bolts 17. A plurality of heat dissipation holes 18 are provided on one side of the control box main body 1. Through the settings of the heat pipe radiator 15, the heat dissipation fins 16, the second bolts 17, and the heat dissipation holes 18, the heat dissipation fins 16 can be fixed on the top of the box door 2 through a plurality of second bolts 17, which can increase the heat dissipation area of the control box main body 1. At the same time, the heat pipe radiator 15 installed inside the control box main body 1 can quickly conduct the heat generated by the operation of the electrical components 3 to the heat dissipation fins 16, and the heat can be quickly dissipated through natural wind. At the same time, the plurality of heat dissipation holes 18 on one side of the control box main body 1 can assist the heat inside the control box main body 1 to be quickly dissipated to the outside of the control box main body 1, thereby preventing the performance of the electrical components 3 from being affected due to the inability to quickly dissipate the temperature inside the control box main body 1.

[0035] As Figure 3 shown in the figure, an electrical control box applicable to harsh environments provided by an embodiment of the present invention. A plurality of limiting plates 19 are fixedly installed on one side of the control box main body 1. A first dust-proof cover 20 that fits the control box main body 1 is arranged between the limiting plates 19. Through the settings of the limiting plates 19 and the first dust-proof cover 20, after the first dust-proof cover 20 is installed between the limiting plates 19 and fits the control box main body 1, it can prevent the first dust-proof cover 20 from falling off the control box main body 1. At the same time, the first dust-proof cover 20 can prevent the dust from the outside from entering the inside of the control box main body 1 through the heat dissipation holes 18 when the temperature inside the control box main body 1 is dissipated, thereby reducing the probability of the dust affecting the electrical components 3.

[0036] As Figure 3 and Figure 7 shown in the figure, an electrical control box applicable to harsh environments provided by an embodiment of the present invention. A plurality of first fixing plates 21 are fixedly installed on the control box main body 1. Limiting rings 22 are fixedly installed at both ends of the first dust-proof cover 20. A first plug rod 23 connected to the limiting ring 22 is movably installed on the first fixing plate 21. A spring 24 connected to the first fixing plate 21 is wound around the first plug rod 23. Through the settings of the first fixing plate 21, the limiting ring 22, the first plug rod 23, and the spring 24, when the first dust-proof cover 20 fits the control box main body 1 between the limiting plates 19, the first plug rod 23 can be engaged with the limiting ring 22 under the elastic action of the spring 24, thereby being able to limit the first dust-proof cover 20 and preventing the risk of the first dust-proof cover 20 slipping off when the control box main body 1 vibrates. After pulling the first plug rod 23 outwards to disengage it from the inside of the limiting ring 22, the first dust-proof cover 20 can be removed, which is convenient for personnel to disassemble and clean the dust on the first dust-proof cover 20.

[0037] As Figure 8 shown, an electric control box applicable to harsh environments provided by an embodiment of the present invention. On the other side of the control box main body 1, a dehumidification port 25 is provided. Inside the dehumidification port 25, a dehumidification fan 26 is arranged. Outside the dehumidification port 25, a second dust-proof cover 27 connected to the control box main body 1 is installed. Through the arrangement of the dehumidification port 25, the dehumidification fan 26 and the second dust-proof cover 27, when the weather is humid, there may be a certain amount of water vapor accumulating inside the control box main body 1, posing a risk of short-circuiting the electrical components 3. When the humidity inside the control box main body 1 exceeds the standard, data will be displayed on the screen display on the front of its box door 2. After being observed by personnel, the dehumidification fan 26 will be immediately started to operate. The dehumidification fan 26 can extract the moisture inside the control box main body 1 and discharge it outward through the dehumidification port 25, so that the inside of the control box main body 1 can be kept dry to avoid affecting the electrical components 3. And the second dust-proof cover 27 can prevent dust from entering the inside of the control box main body 1 through the dehumidification port 25 when the moisture is dissipated outward.

[0038] As Figure 8 shown, an electric control box applicable to harsh environments provided by an embodiment of the present invention. One end of the second dust-proof cover 27 is fixedly installed with a first magnetic ring 28, and a second magnetic ring 29 magnetically connected to the first magnetic ring 28 is fixedly installed on the control box main body 1. Through the arrangement of the first magnetic ring 28 and the second magnetic ring 29, after the two attract each other, the second dust-proof cover 27 can be fixed outside the dehumidification port 25 to prevent it from falling off the control box main body 1. Due to the characteristics of the first magnetic ring 28 and the second magnetic ring 29, the second dust-proof cover 27 can be directly pulled off without tools, so as to facilitate personnel to disassemble and replace the second dust-proof cover 27 when it is damaged, and at the same time, it can also save the time for personnel to disassemble the second dust-proof cover 27.

[0039] As Figure 1 and Figure 9As shown in the figure, an electrical control box suitable for harsh environments provided by an embodiment of the present invention. A support frame 30 is provided at the bottom of the control box main body 1. The support frame 30 is connected to the control box main body 1 through a plurality of third bolts 31. A plurality of connecting legs 32 are fixedly installed at the bottom of the support frame 30. A support leg 33 is sleeved on the connecting leg 32. Connecting holes 34 are formed in both the connecting leg 32 and the support leg 33. A second plug rod 35 is movably installed inside the connecting hole 34. A bolt 36 is fixedly installed at one end of the second plug rod 35. Through the settings of the support frame 30, the third bolts 31, the connecting legs 32, the support legs 33, the connecting holes 34, the second plug rod 35 and the bolt 36, since some control box main bodies 1 are installed outdoors, if there is a strong rain and the water level rises, it may cause the control box main body 1 to be flooded by water. Therefore, in the case of more rainy areas, the control box main body 1 can be installed on the support frame 30 through a plurality of third bolts 31. Then, a plurality of connecting legs 32 at the bottom of the support frame 30 are inserted into the support legs 33. Then, after the connecting legs 32 are lifted upward to a suitable height, the second plug rod 35 is inserted into the connecting hole 34 to connect the connecting legs 32 and the support legs 33. After rotating the second plug rod 35 so that the angle of the bolt 36 is adjusted to be perpendicular to the angle of the connecting hole 34, the connecting legs 32 can be fixed inside the support legs 33 to prevent them from shaking. Lifting the control box main body 1 upward can avoid the risk of it being immersed in rainwater.

[0040] As Figure 2 As shown in FIGS. and the fixing ring 10, an electrical control box suitable for harsh environments provided by an embodiment of the present invention. A waterproof cover 37 is fixedly installed at the top of the support frame 30. A plurality of limiting strips 38 are fixedly installed at one end of the waterproof cover 37. A baffle 39 that fits the waterproof cover 37 is movably installed between the limiting strips 38. A second fixing plate 40 is fixedly installed on the baffle 39. An electric telescopic rod 41 connected to the waterproof cover 37 is installed at the bottom of the second fixing plate 40. Through the settings of the waterproof cover 37, the limiting strips 38, the baffle 39, the second fixing plate 40 and the electric telescopic rod 41, installing the waterproof cover 37 above the control box main body 1 can prevent rainwater from hitting the control box main body 1. Being exposed to rain for a long time will also cause the control box main body 1 to be corroded. At the same time, the baffle 39 can slide between the limiting strips 38, so it will not affect the opening of the box door 2. Starting the electric telescopic rod 41 to run can automatically open or close the baffle 39, so it can save the time for personnel to open and close the baffle 39.

[0041] As shown in the groove 11, the first threaded hole 12 and the first bolt 13, an electrical control box suitable for harsh environments provided by an embodiment of the present invention has a shock-absorbing plate 42 disposed inside the control box body 1. A plurality of second threaded holes 43 are formed in the shock-absorbing plate 42. The shock-absorbing plate 42 is connected to the control box body 1 through a plurality of fourth bolts 44. A shock-absorbing clamping plate 45 is fixedly installed on the shock-absorbing plate 42. A notch 46 for cooperating with the shock-absorbing clamping plate 45 is formed on the back of the electrical component 3. Through the arrangement of the shock-absorbing plate 42, the second threaded holes 43, the fourth bolts 44, the shock-absorbing clamping plate 45 and the notch 46, the shock-absorbing plate 42 can be fixed inside the control box body 1 through a plurality of second threaded holes 43. Due to the characteristics of the shock-absorbing plate 42 itself, it can play a certain shock-absorbing effect on the electrical component 3. And the electrical component 3 is installed on the shock-absorbing clamping plate 45 through the notch 46 on its back. Therefore, the shock-absorbing effect of the electrical component 3 can be further improved, and the loosening of the cable caused by vibration and the displacement of the electrical component 3 can be prevented.

[0042] As Figure 2 shown, an electrical control box suitable for harsh environments provided by an embodiment of the present invention has a chute 47 formed in the limiting strip 38. A slide bar 48 connected to the baffle 39 is movably disposed inside the chute 47. Through the arrangement of the chute 47 and the slide bar 48, the friction between the baffle 39 and the limiting strip 38 can be reduced, making it more labor-saving for the baffle 39 to move between the limiting strips 38. It can not only reduce the power consumption of the electric telescopic rod 41, but also reduce the wear between the limiting strip 38 and the baffle 39.

[0043] The working principle and usage process of the present invention:

[0044] When the control box body 1 needs to be sealed, first push the box door 2 to make it fit on the control box body 1. At this time, the fixing ring 10 on the box door 2 will fit with the corner of the control box body 1. Then remove the first bolt 13 from the inside of the first threaded hole 12, and then push the toggle block 8 upward to make the elastic pull ring 9 approach the fixing ring 10. Then, after the elastic pull ring 9 is inserted into the groove 11 on the fixing ring 10, the toggle block 8 is pressed again to make the elastic pull ring 9 have a downward pulling force, so that the box door 2 can be tightened to make it fit tightly on the control box body 1, thereby avoiding the box In case the door 2 becomes loose, finally screw the first bolt 13 into the first threaded hole 12 to connect the connecting frame 7 and the toggle block 8 together, which can improve the stability of the toggle block 8 and prevent the toggle block 8 from loosening and causing the door 2 to open. At the same time, when the door 2 is attached to the control box body 1, the corrosion-resistant sealing strip 14 on the control box body 1 can be attached to the corrosion-resistant sealing strip 14 on the door 2, which can ensure that the control box body 1 and the door 2 are tightly sealed and prevent corrosive gases and dust from entering. The anti-corrosion paint coating 49 applied on the surface of the control box body 1 can further improve its corrosion resistance.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
