[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the door opening structure of the present application, the partition box is fixedly installed inside the main frame of the distribution box for installing electrical equipment. The electrical equipment is installed on both sides of the partition box to ensure the number of electrical equipment installed and to make full use of the internal space of the main frame of the distribution box. The electrical equipment is closer to the outside of the main frame of the distribution box.

[0020] 2. The present application cooperates with the door panel through the heat dissipation structure. When the door panel is moved up and down, it is convenient for the staff to inspect the electrical equipment fixed in the partition box, and at the same time, the fixing of the filter mesh component 2 is removed, which is convenient for cleaning and replacement of the filter mesh component 2, thereby ensuring the stable and efficient natural heat exchange inside the main frame of the distribution box, and avoiding the impurities adsorbed on the filter mesh component 2 being lifted into the main frame of the distribution box due to the disassembly of the filter mesh component 2.

[0021] 3.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0039] Example: Figure 1-Figure 14 As shown, the present invention provides a technical solution for a high and low voltage distribution cabinet for an emergency power grid that is easy to maintain and operate, including a distribution box main frame 1, a door structure 3 and a door body structure 2 are installed inside the distribution box main frame 1, and a heat dissipation structure 4 is installed on the door structure 3.

[0040] Specifically, since the bottom end of the lower limit frame 24 to which the door panels 21 are fixedly connected passes through the distribution box main frame 1 and extends to the bottom of the distribution box main frame 1, the lower limit frame 24 is sleeved onto the outer side of the locking frame 25 fixedly connected to the distribution box main frame 1, and the lock tongue of the password lock 26 passes through the lock hole on the lower limit frame 24 and is inserted into the locking frame 25, fixing the lower limit frame 24 and the locking frame 25 together, so that the lower limit frame 24 and the door panel 21 fixedly connected to the lower limit frame 24 cannot move up and down, and switch channels 23 are opened on both sides of the top of the distribution box main frame 1, and a T-shaped upper limit frame 22 is inserted into the switch channel 23, and the bottom end of the upper limit frame 22 is fixedly connected to the adjacent door panel 21, and the upper size of the upper limit frame 22 is larger than the switch channel 23, and the upper part of the upper limit frame 22 is pressed on the top of the door panel 21, while limiting the downward movement of the door panel 21, moisture and dust are prevented from entering the inside of the distribution box main frame 1 through the switch channel 23.

[0041] A controller 6 is installed on one side of the distribution box main frame 1. When it is necessary to inspect and repair the distribution box main frame 1 and the distribution electrical equipment installed and protected by the door structure 2, a password is input on the controller 6 on one side of the distribution box main frame 1. The controller 6 controls the password lock 26 electrically connected in the door structure 2 to open, so that the lock tongue of the password lock 26 is retracted. At this time, the upward limit of the lower limit frame 24 is removed, and then the controller 6 controls the forward and reverse motor 319 in the electrically connected door opening structure 3 to work forward.

[0042] Since the output end of the forward and reverse motor 319 is fixedly connected with the transmission shaft 4 38, the transmission shaft 4 38, the transmission shaft 3 36 and the transmission shaft 2 35 are all fixedly installed with the bevel gear 1 310, and the bevel gear 1 310 fixedly installed on the transmission shaft 4 38 is meshed with the other two bevel gears 1 310, when the forward and reverse motor 319 drives the transmission shaft 4 38 to rotate, the transmission shaft 4 38 drives the transmission shaft 3 36 and the transmission shaft 2 35 to rotate through the three bevel gears 1 310, and the rotating transmission shaft 3 36 and the transmission shaft 2 35 are both fixedly installed with the gear box 32, and the two gear boxes 32 receive the rotation force, and the two output ends of the gear box 32 are fixedly installed with the transmission shaft 1 33. At this time, the four transmission shafts 1 33 and the gears 34 fixedly mounted on the outside of the four transmission shafts 1 33 rotate, and the two gear boxes 32 play a role of changing direction, controlling the rotation direction of the gears 34;

[0043] Mounting grooves 27 are provided on both sides of the top of the two door panels 21, and a gear 34 is provided inside each mounting groove 27, and the rack 29 provided inside the mounting groove 27 is fixedly connected to the door panel 21, and the rack 29 is meshed with the gear 34, so the rack 29 moves up under the rotation and push of the gear 34, so that the racks 29 provided on both sides of the door panel 21 move up, and finally, under the action of the four gears 34, the two door panels 21 move up synchronously. When the door panel 21 moves up a certain distance, the forward and reverse motors 319 stop working, and the brakes 37 provided on the outer side of the transmission shaft 2 35 and the brakes 37 provided on the outer side of the transmission shaft 3 36 both work, and the two brakes 37 fixedly installed inside the partition box 31 brake the transmission shaft 2 35 and the transmission shaft 3 36, so that the transmission shaft 2 35 and the transmission shaft 3 36 remain in place, thereby maintaining the door panel 21 in place, so that the electrical equipment installed inside the main frame 1 of the distribution box is exposed.

[0044] In the door opening structure 3, the partition box 31 is fixedly installed inside the distribution box main frame 1 for installing electrical equipment. The electrical equipment is installed on both sides of the partition box 31 to ensure the number of electrical equipment installed, and to make full use of the internal space of the distribution box main frame 1. When the electrical equipment is closer to the outside of the distribution box main frame 1, the electrical equipment will not move and vibrate during the opening and closing process of the door panel 21, thereby reducing the vibration of the electrical equipment caused by the opening and closing of the door panel 21.

[0045] In addition, four storage slots 48 in the heat dissipation structure 4 are provided on both sides of the inside of the distribution box main frame 1, and the four storage slots 48 correspond to the four ventilation slots 411 provided on the outside of the distribution box main frame 1. A second filter mesh 46 is provided inside each of the four storage slots 48. The size of the second filter mesh 46 is larger than the ventilation slot 411. Therefore, the air entering the inside of the distribution box main frame 1 through the ventilation slot 411 needs to be filtered by the second filter mesh 46 before entering the inside of the distribution box main frame 1. While the electrical equipment inside the distribution box main frame 1 dissipates heat, the inside of the distribution box main frame 1 is ensured to be clean.

[0046] In addition, a plurality of iron rings 412 are fixedly connected to one side of the filter mesh member 46, and a magnet member 47 arranged inside the plurality of iron rings 412 is fixedly connected to the main frame 1 of the distribution box. The plurality of iron rings 412 and the plurality of magnet members 47 cooperate to limit one side of the filter mesh member 46, and a clamping plate 49 is fixedly connected to the other side of the filter mesh member 46, and the clamping plate 49 is arranged inside a reserved groove 410 opened on the door panel 21, and the clamping plate 49 cooperates with the reserved groove 410 to limit the other side of the filter mesh member 46, so that the filter mesh member 46 is kept in a close contact with the main frame 1 of the distribution box to filter the air entering the ventilation slot 411;

[0047] When the door panel 21 moves up, the door panel 21 moves up, so that the clamping plate 49 is separated from the reserved groove 410. At this time, one side of the filter mesh 46 loses its limit. The filter mesh 46 is pushed away from the magnet 47, so that the iron ring 412 fixedly connected to the filter mesh 46 can be separated from the magnet 47, and the removal of the filter mesh 46 can be completed. After cleaning or replacing the filter mesh 46, push the filter mesh 46 into the storage groove 48. After the door panel 21 is moved down and reset, the door panel 21 with the reserved groove 410 moves to the outside of the clamping plate 49. After the door panel 21 is reset and locked by the password lock 26, the position of the filter mesh part 46 is fixed;

[0048] Through the cooperation between the heat dissipation structure 4 and the door panel 21, when the door panel 21 is moved up, it is convenient for the staff to inspect the electrical equipment fixed to the partition box 31, and at the same time, the fixing of the filter mesh component 46 is removed, which is convenient for cleaning and replacing the filter mesh component 46, thereby ensuring the stable and efficient natural heat exchange inside the distribution box main frame 1, and avoiding the impurities adsorbed on the filter mesh component 46 from being lifted into the inside of the distribution box main frame 1 due to the disassembly of the filter mesh component 46.

[0049] Embodiment 2: An air guide pipe 42 is fixedly connected to the bottom end of the air inlet pipe 41, and an exhaust fan 43 is fixedly connected between the bottom end of the air guide pipe 42 and the diverter box 44. The air outlet end of the exhaust fan 43 is fixedly connected to the diverter box 44. When the electrical equipment inside the distribution box main frame 1 is working at high power and the heat is serious, the exhaust fan 43 can be controlled to work. The working exhaust fan 43 exhausts air through the air guide pipe 42 and the air inlet pipe 41 and discharges it into the diverter box 44. A battery 5 is fixedly connected to the bottom of the diverter box 44. The battery 5 fills the internal space of the partition box 31 at the bottom of the diverter box 44. The air pressure in the internal space of the partition box 31 at the bottom of the diverter box 44 increases rapidly. The two exhaust slots 45 on both sides of the bottom of the diverter box 44 discharge the airflow into the space on both sides of the battery 5. A plurality of small holes are provided at the bottom of the partition box 31, such as Figure 6 As shown, after the airflow enters the distribution box main frame 1 through the tiny holes, it passes through the filter mesh 46 and is discharged through the ventilation slot 411, taking out the heat inside the distribution box main frame 1, thereby accelerating the heat dissipation inside the distribution box main frame 1.

[0050] The filter mesh 318 is tiltedly arranged on the air inlet pipe 41, and the filter mesh 318 filters the air drawn by the exhaust fan 43 through the air inlet pipe 41, so as to prevent a large amount of dust and impurities from entering the inside of the distribution box main frame 1 when the exhaust fan 43 works to dissipate heat inside the distribution box main frame 1, and the dust and impurities are accumulated on the top of the filter mesh 318;

[0051] Each time the electrical equipment inside the main frame 1 of the distribution box is inspected and repaired, the transmission shaft 35 will be rotated, and an annular groove 312 is provided on the outside of the transmission shaft 35, and the bevel gear 313 fixedly sleeved on the outside of the transmission shaft 35 is arranged inside the annular groove 312. The annular groove 312 provides space for the two bevel gears 313 to work, and the bevel gear 313 fixedly connected to the reciprocating screw 314 is meshed with the bevel gear 313 fixed to the transmission shaft 35, so the rotating transmission shaft 35 is in the two The bevel gear 313 drives the reciprocating screw 314 to rotate. The reciprocating screw 314 connected to the partition box 31 rotates on its own in situ. A support frame 316 is provided on the outside of the reciprocating screw 314 through a nut pair. One end of two limit vertical rods 315 inserted in the support frame 316 is fixedly connected to the partition box 31. Under the limit of the two limit vertical rods 315, the support frame 316 can only move up and down. The rotating reciprocating screw 314 drives the support frame 316 to reciprocate up and down.

[0052] Two transmission shafts 5 317 are fixedly connected to the top of the support frame 316. The top of the transmission shaft 5 317 extends to the inside of the air intake pipe 41 and is fixedly connected to the filter mesh 1 318. Therefore, the support frame 316 drives the filter mesh 1 318 to reciprocate through the transmission shaft 5 317. Since the length of the reciprocating screw rod 314 is limited, the up and down movement of the filter mesh 1 318 is limited. After the filter mesh 1 318 moves up to the limit, the filter mesh 1 318 tilts toward the lower end and is aligned with the bottom of the inner wall at the bend of the air intake pipe 41. The dust and impurities accumulated on the filter mesh 1 318 move to the position where the air intake pipe 41 is tilted under the action of gravity. The dust and impurities leave the inside of the air intake pipe 41 under the action of the tilted inner wall of the air intake pipe 41, thereby completing the cleaning of the dust and impurities on the top of the filter mesh 1 318, reducing the frequency of cleaning and replacement of the filter mesh 1 318, and extending the service life of the filter mesh 1 318.

[0053] In addition, such as Fig.11 As shown, the air intake pipe 41 is configured to be V-shaped, and the opening of the air intake pipe 41 is inclined toward the ground, so rainwater will not enter the air duct 42 through the air intake pipe 41, and the transmission shaft 5 317 passes through the air duct 42 and enters the filter mesh 1 318, and the air duct 42 is arranged inside the sealed partition box 31, so even if a gap is generated between the transmission shaft 5 317 and the air duct 42 due to wear, only the air filtered by the filter mesh 1 318 passes through the gap to enter the partition box 31, and will not cause damage to the internal equipment of the partition box 31.

[0054] In addition, such as Figure 4 , Fig.13 and Fig.14As shown, a limit column 28 is arranged inside the rack 29, and the limit column 28 is fixedly connected to the main frame 1 of the distribution box to play a role in limiting and supporting the rack 29, thereby ensuring the stability of the up and down movement of the rack 29.

[0055] In addition, such as Figure 5 , Figure 6 and Figure 7 As shown, a battery 5 is fixedly connected to the bottom of the shunt box 44. The battery 5 is used to store electricity. When the internal equipment of the distribution box main frame 1 is damaged and cannot provide power for the controller 6, the battery 5 provides power for the controller 6, the door structure 2 and the door opening structure 3 to ensure that the door structure 2 is opened to repair the internal equipment of the distribution box main frame 1. When the controller 6 is completely damaged, the password lock 26 is opened through the lock hole on the password lock 26, so that the door panel 21 loses its limit. Since the top of the transmission shaft 4 38 is fixedly connected with the hexagonal piece 311, and the top of the hexagonal piece 311 extends to the top of the partition box 31 and is rotatably connected to the partition box 31, the hexagonal wrench matching the hexagonal piece 311 can be used to operate the hexagonal piece 311, so that the hexagonal piece 311 drives the transmission shaft 4 38 to rotate, and the door panel 21 is lifted, and the internal equipment of the distribution box main frame 1 can be repaired.

[0056] A plurality of lamps 7 are fixedly connected inside the partition box 31, and the partition box 31 is made of transparent material, so the lamps 7 emit light to illuminate the inside of the distribution box main frame 1, so that the light shines from the opposite side of the staff, avoiding the situation where the staff cannot see the operating position clearly when the light source is behind or above the head, thereby providing convenience for the staff to maintain maintenance.

[0057] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
