Detailed implementation mode

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-14 , an embodiment of the present invention is: a power distribution cabinet with a hierarchical multi-segment function, including a body 1, and further including a shock absorption device; wherein, the shock absorption device includes a bottom plate 21, a first spring 22, a rubber slider 23, a first long rod 24, a second spring 25, a first connecting piece 26, a long plate 27, an elastic telescopic rod 28, a second connecting piece 29 and a long stick 210. The top end of the second spring 25 is fixedly connected to the bottom of the body 1, the bottom plate 21 is fixedly connected to the bottom of the second spring 25, the fixed end of the elastic telescopic rod 28 is fixedly connected to the top of the bottom plate 21, the free end of the elastic telescopic rod 28 is fixedly connected to the bottom of the body 1, the long plate 27 is fixedly connected to the bottom of the body 1, the first connecting piece 26 is fixedly connected to the bottom of the long plate 27, the top of the first long rod 24 is rotatably connected between the two first connecting pieces 26, the second connecting piece 29 is rotatably connected to the bottom of the first long rod 24, the bottom plate 21 is arranged on the ground, the right side of the rubber slider 23 is fixedly connected to the left side of the second connecting piece 29, the left side of the long stick 210 is fixedly connected to the left side of the rubber slider 23. When the rubber slider 23 contacts the inner wall of the chute, a frictional force will be generated, which can disperse the shaking force of the body 1, and effectively prevent the phenomenon that the downward impact force of the power distribution cabinet is too large, resulting in damage to the body 1.

[0021] A chute is opened on the top of the bottom plate 21, the inner wall material of the chute is rubber, and a large frictional force will be generated when the rubber slider 23 contacts the inner wall of the chute.

[0022] One end of the first spring 22 is fixedly connected to the left side of the chute, and the right side of the first spring 22 is fixedly connected to the right side of the rubber slider 23. The first spring 22 will help the rubber slider 23 to return to its position.

[0023] During the operation of this embodiment: When geological activities occur or it rains or blows, the body 1 will shake. When the body 1 shakes, the body 1 will drive the second spring 25 to contract. When the second spring 25 contracts, the second spring 25 will drive the elastic telescopic rod 28 to contract. When the elastic telescopic rod 28 contracts, the elastic telescopic rod 28 will drive the first long rod 24 to rotate. When the first long rod 24 rotates, the first long rod 24 will drive the second connecting piece 29 to slide in the chute. When the second connecting piece 29 slides in the chute, the second connecting piece 29 will drive the rubber slider 23 to move in the chute. When the rubber slider 23 moves in the chute, it will drive the first spring 22 to contract. After the first spring 22 contracts, the first spring 22 will push the rubber slider 23 to return. When the rubber slider 23 slides in the chute, the rubber slider 23 will contact the inner wall of the chute. When the rubber slider 23 contacts the inner wall of the chute, friction will be generated to reduce the sliding speed of the rubber slider 23. When the rubber slider 23 contacts the inner wall of the chute and friction is generated, the shaking force of the body 1 will be dispersed to reduce the excessive downward impact force of the body 1, which may cause damage to the body 1. When the geological activities end or the wind stops, the elastic telescopic rod 28 will drive the second spring 25 to return, and at this time, the first spring 22 will drive the rubber slider 23 to return. Please refer to Figures 1-14 , on the basis of the above embodiment, in another embodiment of the present invention, it further includes a rain shielding device and a fixing device. The rain shielding device includes a triangular inclined block 31, a second long rod 32, a support plate 33, an L-shaped plate 34 and a shielding frame 35.

The first long block 311 is fixedly connected to the other end of the first connecting column 310. One end of the third spring 312 is fixedly connected to the left side of the first long block 311. The support block 314 is fixedly connected to the back of the machine body 1. The other end of the third spring 312 is fixedly connected to the right side of the support block 314. When the shielding frame 35 rises, it will drive the scraper 36 to scrape, which can remove the dust and rainwater that have entered the power distribution cabinet, and can effectively prevent the dust and rainwater from affecting the power distribution cabinet.

[0025] The circumferential surface of the support rod 38 contacts the circumferential surface of the first connecting column 310, and the bottom of the scraper 36 contacts the inner bottom surface of the machine body 1. The scraper 36 can clean the inner bottom wall of the machine body 1.

[0026] The fixing device includes a third long rod 41, an arc-shaped clamp 42, a second fixing block 43, a second connecting column 44, a baffle 45, a threaded rod 46, a nut 47, a baffle plate 48, a third fixing block 49, a stop block 410, and a stop disk 411. The third long rod 41 is fixedly connected to the top of the shielding frame 35. The second fixing block 43 is fixedly connected to the inner back surface of the machine body 1. The second connecting column 44 fixedly penetrates the right side of the second fixing block 43. The right side of the arc-shaped clamp 42 is rotatably connected to the circumferential surface of the second connecting column 44. The threaded rod 46 rotatably penetrates the back of the machine body 1. The nut 47 is threadedly connected to the circumferential surface of the threaded rod 46. The baffle 45 is fixedly connected to the outer surface of the nut 47. The stop disk 411 is fixedly connected to one end of the threaded rod 46 inside the machine body 1. The third fixing block 49 is fixedly connected to the back of the machine body 1. The baffle plate 48 is rotatably connected to the bottom of the third fixing block 49. The stop block 410 is fixedly connected to the bottom of the third fixing block 49. When the shielding frame 35 rises, the shielding frame 35 will drive the nut 47 to rotate, and the rotation of the nut 47 can fix the wire, which can effectively prevent the wire from shaking and falling off.

[0027] The top of the third long rod 41 contacts the baffle 45, the stop disk 411 contacts the arc-shaped clamp 42, the baffle 45 contacts the baffle plate 48, the stop block 410 contacts the baffle plate 48, and the arc-shaped clamp 42 contacts the wire to hold the wire against it.

[0028] During the operation of this embodiment: When the body 1 shakes, the rubber slider 23 will drive the long rod 210 to move. When the rubber slider 23 drives the long rod 210 to move, the long rod 210 will drive the triangular inclined block 31 to move. When the triangular inclined block 31 moves, the triangular inclined block 31 will contact the bottom of the second long rod 32. When the triangular inclined block 31 contacts the bottom of the second long rod 32, the triangular inclined block 31 will push the second long rod 32 upward. When the triangular inclined block 31 pushes the second long rod 32 upward, the second long rod 32 will drive the L-shaped plate 34 to move upward. When the L-shaped plate 34 moves upward, the L-shaped plate 34 will drive the blocking frame 35 to move upward. When the blocking frame 35 moves upward, the blocking frame 35 will block the ventilation opening on the back of the body 1, effectively preventing rainwater or dust from entering the interior of the body 1. When the blocking frame 35 moves upward, the blocking frame 35 will drive the first fixing block 37 to move upward. When the first fixing block 37 moves upward, the first fixing block 37 will drive the support rod 38 to move upward. When the first fixing block 37 drives the support rod 38 to move upward, the support rod 38 will contact the first connecting column 310. When the support rod 38 contacts the first connecting column 310, the first connecting column 310 will drive the connecting block 39 to move towards both sides of the body 1. When the first connecting column 310 drives the connecting block 39 to move towards both sides of the body 1, the connecting block 39 will drive the scraper 36 to move towards both sides of the body 1. When the first connecting column 310 drives the connecting block 39 to move towards both sides of the body 1, the first connecting column 310 will drive the first long block 311 to move towards both sides of the body 1. When the first connecting column 310 drives the first long block 311 to move towards both sides of the body 1, the first long block 311 will drive the third spring 312 to contract. Since the material of the blocking frame 35 is rubber, after the blocking frame 35 moves upward, the friction between the blocking frame 35 and the body 1 will slow down the descending speed of the blocking frame 35. When the blocking frame 35 descends, the third spring 312 will drive the scraper 36 to return to its original position.

[0029] When the retaining frame 35 rises, the retaining frame 35 will drive the third long rod 41 to rise. When the third long rod 41 rises, the third long rod 41 will contact the retaining piece 45. When the third long rod 41 contacts the retaining piece 45, the retaining piece 45 will drive the nut 47 to rotate. When the nut 47 rotates, the nut 47 will move along the track of the threaded rod 46. When the nut 47 moves along the track of the threaded rod 46, the threaded rod 46 will drive the retaining disc 411 to move towards the inner wall of the machine body 1. When the retaining disc 411 moves towards the inner wall of the machine body 1, the retaining disc 411 will contact the arc-shaped clamp 42. When the retaining disc 411 contacts the arc-shaped clamp 42, the free end of the arc-shaped clamp 42 will move towards the inner wall of the machine body 1. When the free end of the arc-shaped clamp 42 moves towards the inner wall of the machine body 1, the arc-shaped clamp 42 will fix the electric wire to prevent the electric wire from shaking and causing electric leakage. When the retaining piece 45 drives the nut 47 to rotate, the retaining piece 45 will contact the front surface of the baffle 48. When the retaining piece 45 contacts the baffle 48, the baffle 48 will rotate. When the nut 47 rotates in reverse, the retaining piece 45 will contact the reverse side of the baffle 48. When the retaining piece 45 contacts the reverse side of the baffle 48, the baffle 48 will be blocked by the retaining block 410 to prevent the nut 47 from continuing to reverse and causing the electric wire to fall off.
