[0013] Furthermore, the movable frame is provided with a fourth sliding groove which is in sliding contact with the first movable shaft.

[0014] Furthermore, a roller is provided at the end of the first movable shaft, and a guide rail that is in rolling contact with the roller is provided on the movable frame.

[0015] Furthermore, it also includes a plurality of legs and a guide sleeve arranged at the bottom of the movable frame and slidably connected to the legs, a spring is arranged between the legs and the movable frame, and an inclined surface is arranged at the end of the legs.

[0016] Furthermore, the protective cover is provided with a plurality of fans, and the power distribution cabinet and the movable frame are respectively provided with a plurality of heat dissipation holes around them.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Under normal circumstances, several distribution cabinets are installed and fixed on the movable frame at the same time and set vertically relative to the ground. At this time, the protective cover is set on the rear side of the distribution cabinet to play a shielding role, preventing foreign objects or falling rain from directly entering the distribution cabinet through the ventilation holes; the lines connecting the distribution cabinet and the electronic components pass through the wire troughs provided on the hinges and extend to the fixed frame to connect with the rest of the external circuits. At the same time, the staff can open the door of the distribution cabinet normally to inspect or replace the electronic components inside the distribution cabinet;

[0019] When rainwater is about to rise to the bottom of the distribution cabinet, the first movable shaft is driven to slide on the first slide groove through the push block. Since the first movable shaft is connected to the distribution cabinet, it will drive the movable frame to rotate clockwise around the hinge, driving several distribution cabinets to move together until the distribution cabinet is level with the ground, thereby moving the bottom of the distribution cabinet to a higher place, avoiding the entry of water into the distribution cabinet after encountering large-scale water accumulation, and improving the safety of high-voltage distribution cabinet operation in bad weather; at the same time, there is no need to move the top of the distribution cabinet in the vertical direction, reducing the vertical space occupied in the process of moving the distribution cabinet, and meeting the needs of protecting the distribution cabinet in relatively narrow places such as basements or tunnels;

[0020] In addition, the push block will simultaneously drive the second movable shaft to slide upward on the second slide slot, cooperate with the sliding connection between the hinge and the third slide slot, and drive the protective cover to rotate counterclockwise around the hinge until the protective cover is wrapped around the outside of the distribution cabinet and the movable frame again, and the protective cover is located on the upper side of the opening of the distribution cabinet to prevent dripping rain or debris from entering the distribution cabinet. At this time, the front of the distribution cabinet faces upward, which can prevent the electronic components inside the distribution cabinet from hanging upside down and falling off the distribution cabinet, thereby improving the safety of the operation of the high-voltage distribution cabinet in bad weather;

[0021] 2. During the rotation of the distribution cabinet, the distribution cabinet rotates around the hinge, and the hinge is fixed on the fixed frame. At the same time, the line connected to the outside world passes through the wire groove of the hinge before connecting to the external circuit. In addition, the line itself has a certain margin to avoid pulling the line during the rotation, causing the line to break or detach from the electronic atom, thereby improving the safety of the high-voltage distribution cabinet in bad weather.

[0022] 3. The spiral block is driven to rotate through the cooperation among the rotating motor, the driving wheel, the semi-convex teeth and the driven gear. At the same time, the sliding rod is driven to slide on the fixed frame through the cooperation among the spiral block, the spiral groove and the column. The first movable shaft and the second movable shaft are driven to slide in the first slide groove and the second slide groove respectively through the cooperation among the push block, the first slider, the second slider, the first movable shaft and the second movable shaft, thereby driving the movable frame and the protective cover to rotate on the fixed frame until the distribution cabinet is away from the flooded area, avoiding the accumulation of water into the distribution cabinet, and improving the safety of the operation of the high-voltage distribution cabinet in bad weather;

[0023] In addition, each time the driving spiral block rotates once, the limit rod provided at the end of the driving wheel will enter the limit groove provided on the driven wheel, and the arc block provided at the end of the limit rod will contact the limit groove. The resistance generated after the two contact will limit the spiral block from continuing to rotate, avoiding that after the position of the protective cover and the distribution cabinet is adjusted, the external force accidentally drives the spiral block to rotate, affecting the stability of the overall structure, and ensuring the safety of the operation of the high-voltage distribution cabinet in bad weather;

[0024] At the same time, after the power distribution cabinet has been rotated, the column stays on the flat groove provided between the two spiral grooves. Since the section of the column is parallel to the flat groove, the force applied by the column on the flat groove cannot drive the spiral block to rotate, thereby realizing the self-locking of the driving mechanism. There is no need to continuously apply power to overcome the gravity of the power distribution cabinet, which improves the stability of the overall structure and ensures the safety of the operation of the high-voltage power distribution cabinet in severe weather.

[0025] 4. When the first movable shaft moves to the top of the first slide groove first, the first slider will be restricted from moving upward. At this time, when the push block is pushed upward further, the first slider will be blocked and cannot move further. However, since the first slider is slidably arranged at the end of the push block, the push block can continue to move upward and drive the second slider to move upward. At the same time, the intermediate gear will move relative to the first rack arranged on the first slider, so that the first gear rotates on the push block and drives the second slider to move further upward until the second movable shaft moves to the top of the second slide groove, thereby driving the protective cover and the power distribution cabinet to rotate to the specified position at the same time. There is no need to separately set up a power device to drive the protective cover and the power distribution cabinet to move respectively, which reduces the space required for the installation of the power device and the manufacturing cost.

[0026] 5. The hinge comprises a first fixed axis rotatably connected to the movable frame, and a second fixed axis slidably connected to the third slide groove. The first fixed axis is located at the lower side of the second fixed axis, so that the movable frame and the protective cover rotate with the first fixed axis and the second fixed axis as fulcrums respectively, ensuring that the protective cover can be as close to the distribution cabinet as possible while avoiding interference between the protective cover and the distribution cabinet during the rotation process, thereby achieving better protection for the distribution cabinet, ensuring the safety of the operation of the high-voltage distribution cabinet in severe weather and reducing the required horizontal length of the protective cover; in addition, the lines pass through the first through hole, the through groove and the second through hole respectively, avoiding interference between the protective cover and the line during the rotation process. At the same time, since the hinge is fixed on the fixed frame, the line is avoided from being pulled during the rotation of the distribution cabinet, causing the line to break or detach from the electronic atom, thereby improving the safety of the operation of the high-voltage distribution cabinet in severe weather.

Under normal circumstances, the protective cover 4 is sleeved on the rear side of the distribution cabinet 2 to play a shielding role to prevent foreign objects or falling rainwater from directly entering the distribution cabinet 2 through the ventilation holes; when the rainwater is about to rise to the bottom of the distribution cabinet 2, the protective cover 4 is located on the upper side of the opening of the distribution cabinet 2 to prevent dripping rainwater or debris from entering the distribution cabinet 2, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in bad weather;

[0043] The two fixing frames 3 are both provided with hinges 5, which are rotatably connected to the movable frame 1 after passing through the protective cover 4. The hinges 5 are provided with a wire groove 6 for the line to pass through. During the rotation of the distribution cabinet 2, the distribution cabinet 2 rotates around the hinges 5, and the hinges 5 are fixedly arranged on the fixing frame 3. At the same time, the line itself has a certain margin to avoid pulling the line during the rotation process, resulting in the line breaking or detaching from the electronic atom, thereby improving the safety of the high-voltage distribution cabinet 2 in operation under severe weather;

[0044] The movable frame 3 further comprises a first movable shaft 7 arranged on both sides of the movable frame 1, and a second movable shaft 8 arranged on both sides of the protective cover 4.

When rainwater is about to rise to the bottom of the distribution cabinet 2, the first movable shaft 7 is driven to slide on the first slide groove 11 by the push block 14. Since the first movable shaft 7 is connected to the distribution cabinet 2, it will drive the movable frame 1 to rotate clockwise around the hinge 5, and drive several distribution cabinets 2 to move together. Until the distribution cabinet 2 is level with the ground, the bottom of the distribution cabinet 2 is moved to a higher place to avoid large-scale water accumulation and the water entering the distribution cabinet 2, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in bad weather; at the same time, there is no need to move the top of the distribution cabinet 2 in the vertical direction, reducing the vertical space occupied by the distribution cabinet 2 during the movement process, meeting the need to protect the distribution cabinet 2 in relatively small places such as basements or tunnels; in addition, the push block 14 will simultaneously drive the second movable shaft 8 upward on the second slide slot 12 Slide, cooperate with the sliding connection between the hinge 5 and the third slide groove 13, drive the protective cover 4 to rotate counterclockwise around the hinge 5, until the protective cover 4 is re-wrapped on the outside of the distribution cabinet 2 and the movable frame 1, and at the same time, the protective cover 4 is located on the upper side of the opening of the distribution cabinet 2 to prevent dripping rain or debris from entering the distribution cabinet 2. At this time, the front of the distribution cabinet 2 is facing upward, which can prevent the electronic components inside the distribution cabinet 2 from being upside down and falling off the distribution cabinet 2, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in severe weather.

The two phases A flat groove 22 in contact with the column 18 is provided adjacent to the spiral groove 21, and the spiral block 19 is driven to rotate by the driving motor 20, so that the spiral groove 21 provided on the spiral block 19 contacts the column 18. The force generated after the two contact will drive the slide bar 17 to slide on the fixed frame 3, and drive the first slider 15 and the second slider 16 provided on one side of the push block 14 to move together, and the first slider 15 and the second slider 16 are respectively in contact with the first movable shaft 7 and the second movable shaft 8, and the component force generated will drive the first movable shaft 7 and the second movable shaft 8 to slide in the first slide groove 11 and the second slide groove 12 respectively, thereby driving the movable frame 1 and the protective cover 4 to rotate on the fixed frame 3 until the distribution cabinet 2 is away from the flooded area, avoiding the accumulation of water from entering the distribution cabinet 2, and improving the safety of the operation of the high-voltage distribution cabinet 2 in bad weather;

[0046] In addition, after the rotation is completed, the column 18 stays on the flat groove 22 provided between the two spiral grooves 21. Since the cross-section of the column 18 is parallel to the flat groove 22, the force applied by the column 18 on the flat groove 22 cannot drive the spiral block 19 to rotate, thereby realizing self-locking of the driving mechanism.

When the push block 14 drives the first movable shaft 7 to slide on the first Y-shaped frame 9, the first movable shaft 7 contacts the fourth slide groove 42. The force generated after the contact between the two will drive the movable frame 1 to rotate around the first fixed shaft 36. At the same time, since the first movable shaft 7 can slide relative to the movable frame 1, the first movable shaft 7 does not need to make a circular motion with the first fixed shaft 36 as the center, thereby reducing the lateral space occupied by the first movable shaft 7 during the sliding process, thereby shortening the lateral space occupied by the first Y-shaped frame 9, and then reducing the space occupied by the installation of the distribution cabinet 2, thereby improving the utilization rate of the distribution room space.

[0053] Preferably, Figure 4 and Fig.10 As shown, it also includes a plurality of legs 45, and a guide sleeve 46 arranged at the bottom of the movable frame 1 and slidably connected to the legs 45. A spring 47 is provided between the legs 45 and the movable frame 1, and an inclined surface 48 is provided at the end of the legs 45. When the distribution cabinet 2 is reset to a vertical state, the inclined surface 48 provided at the end of the legs 45 first contacts the ground, and the component force generated after the contact compresses the spring 47 between the legs 45 and the bracket, so that the legs 45 can further slide in the guide sleeve 46 to avoid hard contact between the legs 45 and the ground, which causes damage to the legs 45. After the distribution cabinet 2 is reset, the rebound force generated by the compression of the plurality of legs 45 and the spring 47 will play a role in supporting the distribution cabinet 2 and improve the stability of the overall structure.

[0054] Preferably, Figure 2 and Fig. 9 As shown, the protective cover 4 is provided with a plurality of fans 49, and the distribution cabinet 2 and the movable frame 1 are respectively provided with a plurality of heat dissipation holes 50 around them, so as to discharge the heat generated by the electronic components inside the distribution cabinet 2 in time and ensure the safety of the operation of the high-voltage distribution cabinet 2 in bad weather.

At this time, the protective cover 4 is set on the rear side of the distribution cabinet 2 to play a shielding role, preventing foreign matter or falling rain from directly entering the distribution cabinet 2 through the ventilation holes; the line connecting the distribution cabinet 2 and the electronic components passes through the wire groove 6 provided on the hinge 5, and extends to the fixed frame 3 to connect with the rest of the external circuits. At the same time, the staff can open the door of the distribution cabinet 2 normally to inspect or replace the electronic components inside the distribution cabinet 2;

[0057] When the rainwater is about to rise to the bottom of the switchboard 2, the first movable shaft 7 is driven to slide on the first slide slot 11 through the push block 14. Since the first movable shaft 7 is connected to the switchboard 2, it will drive the movable frame 1 to rotate clockwise around the hinge 5, driving several switchboards 2 to move together until the switchboard 2 is level with the ground, thereby moving the bottom of the switchboard 2 to a higher place, avoiding the entry of the accumulated water into the switchboard 2 after encountering large-scale water accumulation, and improving the safety of the operation of the high-voltage switchboard 2 in bad weather; at the same time, there is no need to move the top of the switchboard 2 in the vertical direction, reducing The vertical space occupied by the mobile distribution cabinet 2 meets the need to protect the distribution cabinet 2 in relatively narrow places such as basements or tunnels; in addition, during the rotation of the distribution cabinet 2, the distribution cabinet 2 rotates around the hinge 5, and the hinge 5 is fixedly arranged on the fixed frame 3. At the same time, the line connected to the outside world passes through the wire groove 6 of the hinge 5 before connecting to the external circuit. In addition, the line itself has a certain margin, which avoids pulling the line during the rotation process, causing the line to break or detach from the electronic atom, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in bad weather;

[0058] In addition, the push block 14 will simultaneously drive the second movable shaft 8 to slide upward on the second slide groove 12, cooperate with the sliding connection between the hinge 5 and the third slide groove 13, and drive the protective cover 4 to rotate counterclockwise around the hinge 5 until the protective cover 4 is re-wrapped on the outside of the distribution cabinet 2 and the movable frame 1. At the same time, the protective cover 4 is located on the upper side of the opening of the distribution cabinet 2 to prevent dripping rain or debris from entering the distribution cabinet 2. At this time, the front of the distribution cabinet 2 is facing upward, which can prevent the electronic components inside the distribution cabinet 2 from being upside down and falling off the distribution cabinet 2, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in severe weather.

[0059] Example 2

[0060] On the basis of Example 1, Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the driving wheel 26 is driven to rotate by a rotating motor, so that the semi-convex teeth 27 provided on the side of the driving wheel 26 mesh with the driven gear 25, driving the spiral block 19 to rotate, so that the spiral groove 21 provided on the spiral block 19 contacts the column 18, and the force generated after the two contact will drive the slide bar 17 to slide on the fixed frame 3, drive the first slider 15 and the second slider 16 provided on one side of the push block 14 to move together, and contact the first movable shaft 7 and the second movable shaft 8 through the first inclined groove and the second inclined groove provided on the first slider 15 and the second slider 16, respectively, and the generated component force will drive the first movable shaft 7 and the second movable shaft 8 to slide in the first slide groove 11 and the second slide groove 12 respectively, thereby driving the movable frame 1 and the protective cover 4 to rotate on the fixed frame 3 until the distribution cabinet 2 is away from the flooded area, avoiding the accumulation of water from entering the distribution cabinet 2, and improving the safety of the operation of the high-voltage distribution cabinet 2 in bad weather;

[0061] In addition, after each rotation of the driving spiral block 19, the limiting rod 28 provided at the end of the driving wheel 26 will enter the limiting groove 24 provided on the driven wheel 23, and the arc block 29 provided at the end of the limiting rod 28 will contact the limiting groove 24. The resistance generated after the two contact will limit the spiral block 19 from continuing to rotate, so as to avoid the external force accidentally driving the spiral block 19 to rotate after the positions of the protective cover 4 and the distribution cabinet 2 are adjusted, thereby affecting the stability of the overall structure and ensuring the safety of the operation of the high-voltage distribution cabinet 2 in bad weather;

[0062] At the same time, after the distribution cabinet 2 has completed its rotation, the column 18 stays on the flat groove 22 provided between the two spiral grooves 21. Since the cross-section of the column 18 is parallel to the flat groove 22, the force applied by the column 18 on the flat groove 22 cannot drive the spiral block 19 to rotate, thereby realizing self-locking of the driving mechanism. There is no need to continuously apply power to overcome the gravity of the distribution cabinet 2, thereby improving the stability of the overall structure and ensuring the safety of the operation of the high-voltage distribution cabinet 2 in severe weather.

[0063] Example 3

[0064] On the basis of Example 2, Figure 4 and Figure 5As shown, when the first movable shaft 7 first moves to the top of the first slide groove 11, the first slider 15 will be restricted from continuing to move upward. At this time, when the push block 14 is further pushed upward, the first slider 15 will be blocked and cannot continue to move. However, since the first slider 15 is slidably arranged at the end of the push block 14, the push block 14 can continue to move upward and drive the second slider 16 to move upward. At the same time, the intermediate gear 32 will move relative to the first rack 30 provided on the first slider 15, so that the first gear rotates on the push block 14 and drives the second slider 16 to move further upward until the second movable shaft 8 moves to the top of the second slide groove 12, thereby driving the protective cover 4 and the distribution cabinet 2 to rotate to the specified position at the same time. There is no need to separately set up a power device to drive the protective cover 4 and the distribution cabinet 2 to move respectively, thereby reducing the space required for installing the power device and the manufacturing cost.

[0065] Example 4

[0066] On the basis of Example 2, Figure 4 and Figure 8 As shown, the hinge 5 includes a first fixed axis 36 rotatably connected to the movable frame 1, and a second fixed axis 37 slidably connected to the third slide groove 13. The first fixed axis 36 is located at the lower side of the second fixed axis 37, so that the movable frame 1 and the protective cover 4 rotate with the first fixed axis 36 and the second fixed axis 37 as fulcrums respectively, ensuring that the protective cover 4 can be as close to the distribution cabinet 2 as possible while avoiding the interference of the protective cover 4 with the distribution cabinet 2 during the rotation process, thereby achieving a better effect on the protection of the distribution cabinet 2, ensuring the safety of the operation of the high-voltage distribution cabinet 2 in severe weather, and also reducing the required horizontal length of the protective cover 4; in addition, the lines pass through the first through hole 39, the through groove 41 and the second through hole 40 respectively, avoiding the interference of the protective cover 4 with the lines during the rotation process. At the same time, since the hinge 5 is fixed on the fixed frame 3, the lines are avoided from being pulled during the rotation of the distribution cabinet 2, causing the lines to break or detach from the electronic atoms, thereby improving the safety of the operation of the high-voltage distribution cabinet 2 in severe weather.

[0067] Example 5

[0068] On the basis of Example 1, Fig. 9 and Fig.10 As shown, when the push block 14 drives the first movable shaft 7 to slide on the first Y-shaped frame 9, the first movable shaft 7 contacts the fourth slide groove 42, and the force generated after the two contact will drive the movable frame 1 to rotate around the first fixed shaft 36. At the same time, since the first movable shaft 7 can slide relative to the movable frame 1, the first movable shaft 7 does not need to make a circular motion with the first fixed shaft 36 as the center, reducing the lateral space occupied by the first movable shaft 7 during the sliding process, thereby shortening the lateral space occupied by the first Y-shaped frame 9, and further reducing the space occupied by the installation of the distribution cabinet 2, thereby improving the utilization rate of the distribution room space;

[0069] In addition, the roller 43 provided at the end of the first movable shaft 7 and the guide rail 44 provided on the movable frame 1 are in rolling contact, so as to reduce the friction between the first movable shaft 7 and the movable frame 1, thereby facilitating the movable frame 1 to rotate around the first fixed shaft 36, reducing the power required by the power device to overcome the friction, and improving the stability of the overall structure;

[0070] When the distribution cabinet 2 is reset to a vertical state, the inclined surface 48 provided at the end of the leg 45 first contacts the ground. The component force generated after the contact compresses the spring 47 between the leg 45 and the bracket, so that the leg 45 can further slide in the guide sleeve 46, avoiding hard contact between the leg 45 and the ground, which may cause damage to the leg 45. After the distribution cabinet 2 is reset, the rebound force generated by the compression of several legs 45 and the spring 47 will play a role in supporting the distribution cabinet 2 and improve the stability of the overall structure.
