A fixed block is fixed to the outer wall of the bending block, and a return spring is fixed to the side wall of the fixed block. The return spring is fixed to the side wall of the reinforcing block away from the fixed block. A limiting hole is provided on the baffle plate, and the inner wall of the limiting hole is in contact with the outer wall of the bending block. When the reinforcing block moves, it can drive the baffle plate to move. When the reinforcing block moves to the bending block and contacts the inner side of the cabinet door, the bending block will be moved out of the limiting hole due to the extrusion force, thereby releasing the limit on the baffle plate.

[0014] The present invention provides a power distribution cabinet with a protective function. It has the following beneficial effects:

[0015] 1. When the protective plate of the present invention encounters a severe impact, the buffer rod will move toward the base, causing the buffer spring to stretch and deform, thereby being able to buffer the force of animals and the like impacting the bottom of the cabinet, preventing the cabinet from being damaged, and achieving a buffering and shock-absorbing effect; and when the impact force on the protective plate is too large, the buffer rod will drive the arc block to squeeze the inclined surface of the inclined plate, thereby enabling the inclined plate to move upward, and through the cooperation of the hinged rod, the blocking block is removed from the surface of the T-block, releasing the limit on the cabinet, and through the cooperation of the connecting spring, the support rod can drive the cabinet to move upward for lifting, so that the height of the cabinet is increased, thereby preventing the bottom of the cabinet from being damaged by severe impact.

[0016] 2. When the cabinet is lifted, the transmission plate will move on the L-shaped extrusion plate, so that the L-shaped extrusion plate will squeeze the inclined surface of the transmission plate, and the transmission plate will squeeze the elastic switch of the alarm, so that the alarm will be turned on, thereby sending out an alarm sound, which has the effect of scaring animals and alerting staff; when the transmission plate moves, through the cooperation of the T-bar and the hinge block, the rubber wheel can be squeezed on the surface of the electrical equipment to reinforce the electrical equipment, thereby preventing the cabinet from being hit back and forth and causing the electrical equipment inside the cabinet to shake and be damaged.

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1-Figure 9An embodiment of the present invention is: a power distribution cabinet with a protective function, comprising a base 1 and a cabinet 2, the cabinet 2 is arranged on the top of the base 1, and an electrical device 3 is detachably installed in the cabinet 2, a buffer rod 4 is passed through the side wall of the base 1, a protective plate 5 is fixed to one end of the buffer rod 4, an arc block 7 is fixed to the other end of the buffer rod 4, a buffer spring 6 is fixed to the side wall of the arc block 7, and the side of the buffer spring 6 away from the arc block 7 is fixed to the inner side of the base 1, and a lifting component for protecting the cabinet 2 is arranged on the base 1; wherein the lifting component comprises a sleeve 81, a support rod 82, a connecting spring 83, a fixing rod 84, a bevel plate 86, a disc 85, a slide plate 88, a reset spring 87, a hinged rod 89, a block 810, and a T-block 811, the sleeve 81 is fixed to the inner wall of the base 1, and the inner wall of the sleeve 81 A support rod 82 is slidably installed, a connecting spring 83 is fixed at the bottom of the support rod 82, the bottom of the connecting spring 83 is fixed to the inner wall of the sleeve 81, the top of the support rod 82 is fixedly connected to the bottom of the cabinet 2, a fixing rod 84 is fixed to the inner side of the base 1, a disc 85 is fixed to the top of the fixing rod 84, a sloped disk 86 is slidably installed on the outer wall of the fixing rod 84, a return spring 87 is fixed to the bottom of the sloped disk 86, the bottom of the return spring 87 is fixed to the inner side of the base 1, a slide plate 88 is slidably installed on the top of the disc 85, a hinged rod 89 is hinged on the slide plate 88, and one end of the hinged rod 89 away from the slide plate 88 is hinged to the top of the sloped disk 86, a T-block 811 is fixed to the bottom of the cabinet 2, a clamping block 810 is fixed to the top of the slide plate 88, and the inner side of the clamping block 810 fits with the inner side of the T-block 811.

[0030] By providing the protective plate 5, the buffer rod 4 and the buffer spring 6, the side wall of the cabinet 2 can be protected. When the bottom of the cabinet 2 is hit by an animal, the protective plate 5 will be squeezed closer to the cabinet 2. The buffer rod 4 and the buffer spring 6 cooperate to buffer the impact force, thereby achieving a protective effect.

[0031] When one of the surfaces of the protective plate 5 is subjected to a severe impact, the arc block 7 will squeeze the inclined surface of the inclined plate 86, so that the inclined plate 86 can move upward under the squeezing force. When the inclined plate 86 moves upward, the inclined plate 86 will squeeze the hinge rod 89, so that the hinge rod 89 will rotate at the hinge, so that the two groups of slides 88 will move away from each other at the top of the disc 85, so that the slide plate 88 can drive the block 810 to move away from the top of the T-block 811, and release the limit on the cabinet 2. Through the cooperation of the connecting spring 83, the support rod 82 can drive the cabinet 2 to lift up, so that the cabinet 2 is raised, thereby preventing the bottom of the cabinet 2 from being damaged by severe impact.

[0032] When the present embodiment is working, when the bottom of the outdoor power distribution cabinet is hit by an animal, the protective plate 5 is subjected to an extrusion force, so that the protective plate 5 is moved closer to the base 1, so that the buffer rod 4 drives the arc block 7 to move in the base 1, so that the buffer spring 6 is stretched to buffer the impact force, and when the protective plate 5 is hit violently, the arc block 7 is moved in the base 1 to contact the bottom inclined surface of the inclined plate 86, so that the arc block 7 is pressed against the bottom inclined surface of the inclined plate 86, so that the inclined plate 86 moves upward, and when the inclined surface When the disk 86 moves upward, the reset spring 87 will be stretched. When the inclined disk 86 moves upward, the inclined disk 86 can squeeze the hinge rod 89, causing the hinge rod 89 to rotate at the hinge, so that the hinge rod 89 squeezes the slide plate 88 to move on the top of the disk 85, so that the slide plate 88 drives the block 810 to move away from the top of the T-block 811, thereby releasing the limit on the cabinet 2. Because the connecting spring 83 is in compression, the connecting spring 83 can drive the support rod 82 and the cabinet 2 to move upward, thereby lifting the cabinet 2.

[0033] When the protective plate 5 is not subjected to the impact force, the buffer spring 6 is in a stretched state, and the buffer spring 6 can drive the arc block 7 and the buffer rod 4 to reset, so that the protective plate 5 is reset. When the arc block 7 is reset, the bottom slope of the inclined plate 86 is not subjected to the extrusion force, and because the reset spring 87 is in a stretched state, the inclined plate 86 is moved downward, and the inclined plate 86 is moved downward to pull the hinge rod 89, so that the hinge rod 89 is rotated at the hinge, so that the hinge rod 89 pulls the two sets of slide plates 88 on the disc 85 to approach each other, so that the block 810 is reset. When the cabinet 2 needs to be repaired, When resetting, the cabinet 2 can be pressed to move downward. When the T-block 811 at the bottom of the cabinet 2 moves to contact the inclined surface of the block 810, the inclined surface of the block 810 continues to be squeezed, so that the block 810 is subjected to the squeezing force and drives the two sets of slides 88 away from each other. When the T-block 811 moves to the inner side of the bottom of the block 810, because the block 810 is not subjected to the squeezing force, the slide 88 can be squeezed to reset through the reset spring 87 and the hinge rod 89, so that the block 810 limits the T-block 811, and the cabinet 2 is reset and fixed, preventing the cabinet 2 from being in a raised state all the time, which is inconvenient for the maintenance of the cabinet 2.

[0034] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, the cabinet 2 is provided with an alarm component and an auxiliary component for secondary protection; the alarm component includes an L-shaped extrusion plate 92, an L-shaped support plate 91, a transmission plate 96, a transmission spring 95, an alarm 93, an elastic switch 94, a T-shaped rod 97, a hinge block 98, a through hole 910 and a rubber wheel 99; the L-shaped extrusion plate 92 is fixed to the top of the base 1, the side wall of the cabinet 2 is fixed with an L-shaped support plate 91, the inner side of the L-shaped support plate 91 is slidably mounted with a transmission plate 96, and the side wall of the transmission plate 96 is fixed with a transmission spring 95, the side of the transmission spring 95 away from the transmission plate 96 is fixed on the inner side of the L-shaped support plate 91, the side wall of the cabinet 2 is fixed with an alarm 93, the alarm 93 is installed with an elastic switch 94, and the elastic switch 94 is electrically connected to the alarm 93, the side wall of the transmission plate 96 is fixed with a T-bar 97, the T-bar 97 passes through the side wall of the cabinet 2, and the penetration is slidably connected, the inner wall of the cabinet 2 is hinged with a hinge block 98, the hinge block 98 is provided with a through hole 910, the T-bar 97 passes through the through hole 910, and the penetration is fitted, and the side wall of the hinge block 98 is rotatably installed with a rubber wheel 99.

[0035] By opening the elastic switch 94, the alarm 93 can be operated and emit a buzzing sound, which can drive away animals and alert staff. There are two sets of rubber wheels 99, and the two sets of rubber wheels 99 are symmetrically arranged with the center line of the cabinet 2 in the vertical direction as the symmetry axis, and the electrical equipment 3 is squeezed by the cooperation of the two sets of rubber wheels 99, so as to improve the stability of the electrical equipment 3 in the cabinet 2 and prevent the electrical equipment 3 from shaking and being damaged in the cabinet 2 when the distribution cabinet is hit back and forth.

[0036] In addition, the auxiliary components include a slider 1001, an extrusion rod 1002, a reinforcement block 1003, a rubber plate 1005, a movable rod 1004, a baffle 1006, a push spring 1007, a bending block 1008, a fixed block 1009, a limit hole 1011 and a return spring 1010; the slider 1001 is slidably installed on the inner wall of the cabinet 2, the side wall of the hinge block 98 is fixed with an extrusion rod 1002, the extrusion rod 1002 passes through the middle opening of the slider 1001, and the penetration is fitted, the inner wall of the cabinet 2 is slidably installed with a reinforcement block 1003, the side wall of the reinforcement block 1003 is fixed with a rubber plate 1005, the side wall of the reinforcement block 1003 is hinged with a movable rod 1004, and the end of the movable rod 1004 away from the reinforcement block 1003 is hinged to the top of the slider 1001 A baffle plate 1006 passes through the reinforcing block 1003, and the baffle plate 1006 is slidably connected to the penetration point of the reinforcing block 1003. A push spring 1007 is fixed to the side wall of the top protrusion of the reinforcing block 1003, and the side of the push spring 1007 away from the alarm 93 is fixed to the top protrusion of the baffle plate 1006. A bending block 1008 passes through the reinforcing block 1003, and the penetration point is slidably connected. A fixed block 1009 is fixed to the outer wall of the bending block 1008, and a return spring 1010 is fixed to the side wall of the fixed block 1009, and the side of the return spring 1010 away from the fixed block 1009 is fixed to the side wall of the reinforcing block 1003. A limiting hole 1011 is provided on the baffle plate 1006, and the inner wall of the limiting hole 1011 is in contact with the outer wall of the bending block 1008.

[0037] Two groups of reinforcing blocks 1003 are provided, and the two groups of reinforcing blocks 1003 are symmetrically arranged with the center line of the cabinet body 2 in the vertical direction as the symmetry axis. Through the movement of the reinforcing blocks 1003, the rubber plate 1005 is squeezed and fitted with the inner wall of the cabinet door of the cabinet body 2, so that the rubber plate 1005 applies an outward force to the cabinet door, thereby preventing the cabinet body 2 from being damaged by impact.

[0038] There are two groups of baffles 1006, and the two groups of baffles 1006 are symmetrically arranged with the center line of the cabinet body 2 in the vertical direction as the symmetry axis. By setting the baffles 1006, a secondary protection effect can be achieved to prevent the cabinet door of the cabinet body 2 from being deformed by impact, which will cause the deformed door panel to squeeze the control surface of the electrical equipment 3, easily causing damage to the electrical equipment 3.

[0039] When the present embodiment is working, when the cabinet 2 is lifted, the L-shaped support plate 91 is driven to move upward, thereby enabling the transmission plate 96 to move upward. When the transmission plate 96 moves upward until the inclined surface of the transmission plate 96 contacts the protrusion of the L-shaped extrusion plate 92, and when the cabinet 2 continues to drive the L-shaped support plate 91 and the transmission plate 96 to move upward, the inclined surface of the transmission plate 96 is subjected to an extrusion force, thereby causing the transmission plate 96 to approach the cabinet 2, causing the transmission plate 96 to drive the transmission spring 95 to stretch, and when the transmission plate 96 moves, the elastic switch 94 on the alarm 93 is pressed. When the transmission plate 96 moves into the cabinet 2, the T-shaped rod 97 is driven to move, so that the T-shaped rod 97 is driven to squeeze the through hole 910 in the hinge block 98, so that the hinge block 98 is rotated upward at the inner wall hinge of the cabinet 2, so that the hinge block 98 drives the rubber wheel 99 to rotate, so that the rubber wheel 99 can squeeze and reinforce the electrical equipment 3 in the cabinet 2;

[0040] When the cabinet 2 moves downward and returns to its original position, the L-shaped extrusion plate 92 will not squeeze the inclined surface of the transmission plate 96. Because the transmission spring 95 is in a stretched state, the transmission spring 95 will drive the transmission plate 96 to reset, so that the transmission plate 96 does not squeeze the elastic switch 94, so that the elastic switch 94 is reset and the alarm 93 is turned off. When the transmission plate 96 moves, the transmission plate 96 can drive the T-bar 97 to reset, so that the T-bar 97 drives the hinge block 98 to rotate downward on the inner wall of the cabinet 2, so that the two sets of rubber wheels 99 do not apply an extrusion force to the electrical equipment 3, preventing the electrical equipment 3 from being deformed by applying an extrusion force to the outer wall of the electrical equipment 3 for a long time. When the hinge block 98 rotates upward, the extrusion rod 1002 can squeeze the middle position of the slider 1001, driving the slider 1001 to move upward. When the slider 1001 moves upward, the movable rod 1004 The movable rod 1004 is squeezed to rotate at the hinge, and the movable rod 1004 squeezes the reinforcing block 1003 to move closer to the cabinet door, so that the rubber plate 1005 can squeeze the inner side of the cabinet door of the cabinet body 2, thereby reinforcing the cabinet door and preventing the cabinet door from being damaged by impact. When the reinforcing block 1003 approaches the cabinet door, the bending block 1008 will come into contact with the inner side of the cabinet door of the cabinet body 2, so that the bending block 1008 will be subjected to the squeezing force, so that the bending block 1008 drives the fixed block 1009 to move, so that the return spring 1010 is stretched, and the bending block 1008 is moved out of the limiting hole 1011, and the limiting of the baffle plate 1006 is released. Because the push spring 1007 is originally in a compressed state, the push spring 1007 drives the two groups of baffle plates 1006 to approach each other, so that the control surface of the electrical equipment 3 of the baffle plate 1006 is blocked, thereby achieving the effect of secondary protection.

[0041] When the hinge block 98 rotates downward, the extrusion rod 1002 will squeeze the slider 1001 and move downward, so that the movable rod 1004 will pull the reinforcement block 1003, so that the reinforcement block 1003 and the rubber plate 1005 will return to their original positions. By opening the cabinet door, the baffle plate 1006 can be pushed to reset, so that the push spring 1007 is compressed to expose the control surface of the electrical equipment 3. When the baffle plate 1006 moves to the limiting hole 1011 to align with the bending block 1008, the return spring 1010 is in a stretched state, so that the bending block 1008 can extend into the limiting hole 1011 to fix the baffle plate 1006.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
