[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] See also Figure 1-10, a power distribution cabinet for an intelligent power grid provided by an embodiment of the present invention includes a cabinet body 1, a cabinet opening 2 is provided on one side of the cabinet body 1, and further includes: a first door panel 3, which is hinged to the inner top surface of the cabinet opening 2 and has a first position where it fits and blocks the cabinet opening 2 and a second position where it horizontally extends outside the cabinet opening 2 during its rotation; a second door panel 4, one end of which is hinged to the first door panel 3 and the other end is connected to the inner wall of the cabinet opening 2 in a lifting and movable manner; when the first door panel 3 is in the first position, the first door panel 3 and the second door panel 4 completely block the cabinet opening 2; a limiting component, which is arranged on the first door panel 3 and is used to limit the rotation of the second door panel 4 relative to the first door panel 3 at the first position and the second position of the first door panel 3.

[0036] Specifically, the cabinet body 1 has a rectangular frame structure; one side of the cabinet body 1 is open, and a cabinet opening 2 is provided on this open side, and the size of the cabinet opening 2 is larger than the circumference of the open side of the cabinet body 1; the cabinet opening 2 has a certain concave depth towards the inner side of the cabinet body 1; the bottom surface of the cabinet opening 2 is inclined and slides downwards towards the outside to facilitate drainage. One end of the first door panel 3 is hinged to the inner top surface of the cabinet opening 2, the inside of the first door panel 3 is hollow and extends to the other end, and the cross-section of the first door panel 3 is in a "匚" shape; one end of the second door panel 4 hinged to the first door panel 3 is embedded inside the first door panel 3, so that when the first door panel 3 is in the second position, when the second door panel 4 obliquely supports the first door panel 3, the second door panel 4 is completely located below the first door panel 3 and is not affected by rain and snow; a chute 5 is provided on the inner wall of the cabinet opening 2, and a sliding rod 6 matching the chute 5 is provided at one end of the second door panel 4 away from the hinge with the first door panel 3; under the limitation of the sliding rod 6 and the chute 5, the second door panel 4 keeps one end fitting the inner wall of the cabinet opening 2 and moves up and down, and when the first door panel 3 is in the first position, the inner sides of the first door panel 3 and the second door panel 4 are coplanar and synchronously fit the cabinet opening 2 to achieve complete closing and blocking of the cabinet opening 2; the above structure makes the first door panel 3 and the second door panel 4 form an up-and-down folding cabinet door. When the limiting component limits the rotation of the second door panel 4 relative to the first door panel 3, that is, the angle between the first door panel 3 and the second door panel 4 is fixed, and further limits the positions of the first door panel 3 and the second door panel 4 on the cabinet opening 2. In the actual use of this technical solution, when the cabinet opening 2 needs to be opened, the first door panel 3 rotates upwards to the second position where it horizontally extends outside the cabinet opening 2, and the second door panel 4随之 rotates and moves upwards to form an inclined support under the first door panel 3. At the same time, the limiting component limits the rotation of the second door panel 4 relative to the first door panel 3, thereby ensuring that the first door panel 3 is in the second position, which can achieve blocking rain and snow during door opening and maintenance in rainy and snowy weather. In addition, when the cabinet opening 2 is closed, the limitation of the rotation of the second door panel 4 by the limiting component is cancelled, and then the first door panel 3 returns to the first position, and the second door panel 4随之 rotates and moves downwards, so that the first door panel 3 and the second door panel 4 both fit on the cabinet opening 2 to achieve complete blocking. Since the first door panel 3 always contacts rain and snow on the outside, in the first position, it only faces the inside of the cabinet body 1, thereby preventing the rain and snow adhered to the door panel from being brought into the cabinet body 1.

[0037] Compared with the prior art, an intelligent power distribution cabinet for a power grid proposed in an embodiment of the present invention has a folding structure composed of a first door panel 3 and a second door panel 4. When the cabinet opening 2 is opened, the first door panel 3 rotates to a second position horizontally suspended outside the cabinet opening 2, and the second door panel 4 moves accordingly to be tilted and supported under the first door panel 3. At the same time, the limiting component limits the rotation of the second door panel 4 relative to the first door panel 3, thereby ensuring that the first door panel 3 is in the second position, which can block rain and snow when the door is opened for maintenance in rainy and snowy weather. In addition, when the first door panel 3 is returned to the first position, since the first door panel 3 is always in contact with rain and snow with the outer side, when in the first position, it only faces the inner side to the cabinet body 1, thereby preventing the door panel from bringing the attached rain and snow into the cabinet body 1.

[0038] As the preferred technical scheme of this embodiment, the limit assembly includes a convex shell 7 arranged on the outer side of the first door panel 3, and a plug rod 8 is elastically and movably arranged on the convex shell 7, one end of the plug rod 8 extends into the inner side of the first door panel 3, and the outer wall of the hinged end of the second door panel 4 and the first door panel 3 is provided with two sockets 9 matching the plug rod 8, and the other end of the plug rod 8 is fixedly provided with a handle 10. Specifically, the convex shell 7 protrudes out of the outer side of the first door panel 3, and the handle 10 is arranged on the outer side of the convex shell 7 to form a gap between the outer wall of the first door panel 3 to facilitate the operation of the handle 10; the plug rod 8 vertically penetrates the first door panel 3, and the extension direction and the movement direction of the plug rod 8 are both radially arranged along the rotation axis of the second door panel 4; the elastic force exerted on the plug rod 8 keeps it moving toward the inner side of the first door panel 3, and then when the plug rod 8 corresponds to the socket 9, the plug rod 8 automatically remains inserted into the socket 9; the two sockets 9 respectively correspond to the positions where the second door panel 4 rotates relative to the first door panel 3 when the first position and the second position of the first door panel 3, so that the two sockets 9 correspond to the plug rods 8 respectively. In actual use of the present technical solution, when the first door panel 3 is switched from the first position to the second position, the handle 10 is first pulled, and the handle 10 drives the insertion rod 8 to leave the corresponding socket 9 at this time. Then, an upward force is applied to the handle 10, and the handle 10 drives the first door panel 3 to rotate upward, and the first door panel 3 drives the second door panel 4 to move upward, and the second door panel 4 rotates relative to the first door panel 3; when the first door panel 3 reaches the second position, the other socket 9 on the second door panel 4 corresponds to the insertion rod 8, then the handle 10 is slowly released while keeping the first door panel 3 in the second position, and the insertion rod 8 is automatically inserted into the corresponding socket 9 at this time under the action of elasticity, thereby limiting the rotation of the second door panel 4 relative to the first door panel 3, and also stabilizing the first door panel 3. The second door panel 4 tilts to support the first door panel 3, and the first door panel 3 remains in the second position; when the first door panel 3 switches from the second position to the first position, the handle 10 is also pulled to allow the handle 10 to move relative to the first door panel 3 to drive the insertion rod 8 to leave the socket 9, and then the first door panel 3 is immediately pressed down to rotate the first door panel 3 downward, and the second door panel 4 moves downward accordingly and rotates relative to the first door panel 3; when the first door panel 3 arrives at the first position, the second door panel 4 and the first door panel 3 are coplanarly fitted on the vertical plane to block the cabinet opening 2, and the other socket 9 on the second door panel 4 corresponds to the insertion rod 8 again, and the handle 10 is released, and the insertion rod 8 is automatically inserted into the corresponding socket 9 at this time to stabilize the positions of the first door panel 3 and the second door panel 3.

[0039] As a preferred technical solution of this embodiment, a convex ring 11 fixedly connected to the insertion rod 8 is movably provided in the convex shell 7, and an elastic member 12 is provided between one side of the convex ring 11 and the inner wall of the convex shell 7. Specifically, the elastic member 12 may preferably be a spring, which is sleeved on the insertion rod 8; the elastic member 12 is provided on the side of the convex ring 11 close to the handle 10, and the elastic member 12 abuts against the inner wall of the convex shell 7 and the convex ring 11 on both sides by abutting, thereby achieving the tendency of the insertion rod 8 to maintain moving toward the first door panel 3.

[0040] In another embodiment of the present invention, a plurality of air holes 13 are provided on the first door panel 3, a baffle 14 is movably provided on the inner side of the first door panel 3, a plurality of connecting holes 15 are provided on the baffle 14, the insertion rod 8 can be rotatably provided, and is linked with the baffle 14 through a linkage assembly. Specifically, the plurality of air holes 13 are arranged equidistantly in the longitudinal direction; the upper and lower ends of the baffle 14 are movably embedded in the first door panel 3, and the baffle 14 slides laterally; the plurality of connecting holes 15 are matched with the air holes 13 one by one, and when the baffle 14 slides laterally, the air holes 13 correspond to the connecting holes 15, and the first door panel 3 is ventilated, and the air holes 13 and the connecting holes 15 are completely staggered, and the first door panel 3 is closed, which can be used to assist the cabinet 1 in hot weather outdoors to dissipate heat from the inside to the outside, and ensure closure under other conditions; the insertion rod 8 can be rotated by operating the handle 10, and preferably, the handle 10 can be set with a rotation range of 90°. When it is horizontally placed, the corresponding first door panel 3 is closed, and when it is vertically placed, the corresponding first door panel 3 is ventilated.

[0041] As the preferred technical solution of this embodiment, the linkage assembly includes a gear 16 that is synchronously rotated on the insertion rod 8, and a rack 17 that meshes with the gear 16 is provided on the baffle 14. Specifically, a keyway is provided on the insertion rod 8, and a key block is provided on the inner side of the gear 16. The setting of the keyway and the key block ensures that the gear 16 rotates synchronously with the insertion rod 8 and does not affect the axial movement of the insertion rod 8; the insertion rod 8 rotates, driving the gear 16 to rotate, and the gear 16 meshes with the rack 17 for transmission, so as to drive the baffle 14 to move laterally, thereby controlling the correspondence or misalignment of the air vent 13 and the connecting hole 15.

[0042] As a preferred technical solution of this embodiment, annular convex grooves 18 are provided on the side of the convex ring 11 away from the elastic member 12 and on the inner side of the convex shell 7 close thereto. Specifically, the convex grooves 18 are arranged such that when the convex ring 11 is pushed by the elastic force of the elastic member 12 and keeps in contact with the inner side of the convex shell 7, the convex grooves 18 on both sides engage with each other to limit the free rotation of the convex ring 11, that is, to limit the rotation of the insertion rod 8, thereby stabilizing the position of the baffle 14, that is, to stabilize the ventilation or closed state of the first door panel 3.

[0043] In another embodiment of the present invention, a damping component for hindering the movement of the second door panel 4 is provided at the lower end of the cabinet opening 2. Specifically, the damping component is provided to provide buffering in the last section of the descent and closure of the second door panel 4 to avoid vibration caused by rigid collision and to avoid pinching the operator.

[0044] As a preferred technical solution of this embodiment, the damping component includes a groove 19 arranged on the inner wall of the inner side of the cabinet opening 2 and parallel to the first door panel 3 at the first position, a plurality of connecting pins 20 are arranged at intervals up and down on the inner side of the groove 19, an arc-shaped spring piece 21 is connected between each two adjacent connecting pins 20, the lowermost connecting pin 20 is hinged to the inner wall of the groove 19, and the other connecting pins 20 can be moved up and down in the groove 19, the middle part of the arc-shaped spring piece 21 protrudes outward from the groove 19 in a free state and the outer wall of the arc-shaped spring piece 21 is roughly arranged, specifically, the groove 19 is vertically arranged, the axial direction of the connecting pin 20 is parallel to the axial direction of the sliding rod 6 on the second door panel 4; the arc-shaped spring piece 21 is elastic, elastically bends in a free state, and the bent convex end protrudes outside the groove 19, and the two ends of the arc-shaped spring piece 21 are respectively connected to the two adjacent connecting pins 20; the lowermost connecting pin 2 0 is hinged with the groove 19 to determine that the lowermost end position of each connecting pin 20 and the arc-shaped spring piece 21 is fixed; when the arc-shaped spring piece 21 is compressed and tends to be flat, the distance between its two ends is expanded, and when it elastically recovers and bends, the distance between its two ends is reduced, and then under the condition that the height of the lowermost connecting pin 20 is fixed, the height of the uppermost connecting pin 20 rises and falls; the arc-shaped spring piece 21 protrudes out of the groove 19, that is, it is blocked in the descending stroke of the lower end of the second door panel 4, and the outer side of the arc-shaped spring piece 21 is roughened, so that during the descending process of the lower end of the second door panel 4, it can hinder its descent, and because the downward direction exerts force on the arc-shaped spring piece 21, the arc-shaped spring piece 21 is less likely to be compressed and has a better buffering effect; when the second door panel 4 vertically closes the cabinet opening 2, its inner side simultaneously presses each arc-shaped spring piece 21, and each arc-shaped spring piece 21 stretches synchronously to make the uppermost connecting pin 20 rise to the highest position.

[0045] As a preferred technical solution of this embodiment, a floating block 22 is fixedly provided on the uppermost connecting pin 20, a spring switch 23 is provided on the top surface of the groove 19, a lamp body 24 electrically connected to the spring switch 23 is provided in the cabinet 1, and a partition block 25 which can control the spring switch 23 to be disconnected is provided on the upper end of the floating block 22. When the first cabinet 1 is in the first position, the second cabinet 1 is synchronously fitted to block the cabinet opening 2, and then the second cabinet 1 presses each arc spring 21 to make the uppermost connecting pin 20 rise to the highest position. Specifically, the floating block 22 is arranged to move up and down within the upper end range of the groove 19; the spring switch 23 includes two elastic conductive springs, and a power supply for supplying energy to the lamp body 24 is provided inside the cabinet 1. The two conductive springs are respectively The positive and negative poles of the power supply are connected, and the two conductive springs are in a free state and fit each other to keep the power on; the partition block 25 is vertically opposite to the middle position of the two conductive springs, and a tip is set on the spring; when the second door panel 4 vertically closes the cabinet opening 2, the uppermost connecting pin 20 rises to the highest position. At this time, the uppermost connecting pin 20 drives the floating block 22 to rise, so that the partition block 25 at the upper end of the floating block 22 is inserted between the two conductive springs of the spring switch 23 to achieve a circuit break, and the lamp body 24 can be automatically closed. When the second door panel 4 is opened upward, the floating block 22 is driven by the automatic retraction of the arc spring 21 to descend, so that the partition block 25 avoids the spring switch 23, and the lamp body 24 can be automatically lit, which is convenient for maintenance operations in the cabinet 1 at night.
