Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box protection device for electric power. Background Art

[0002] The distribution box is a massive parameter on the data. It is generally used to form a low-voltage forest according to the electrical wiring. It requires that the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment be assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection effect.

[0003] According to a disclosed protective device for a distribution box (Announcement No.: CN216750824U), the above application includes a distribution box body, a shielding component for preventing rain and snow from damaging the distribution box body, and a protective component for protecting the distribution box body, the shielding component includes a shielding plate arranged above the distribution box body, a guide rod arranged at the top of the distribution box body, a limit plate arranged at the top of the guide rod, a horizontal plate arranged in the shielding plate, a first spring sleeved on the outside of the guide rod, a motor arranged at the top of the distribution box body, a first rotating shaft connected to the motor, and a first cam sleeved on the outside of the first rotating shaft. The present application solves the problem that the existing distribution box lacks a protective device when used outdoors, and when it is hit, it is easy to cause damage to internal components. In rainy and snowy weather, rain and snow are easy to accumulate on the top of the distribution box, which is easy to deform the distribution box and also easy to cause corrosion to the distribution box.

[0004] The above-mentioned distribution box protection equipment clears the snow on the top of the shielding plate by starting the motor by the staff. Because the distribution box is placed outdoors, the staff needs to observe that there is snow on the top of the shielding plate before starting the motor to clear the snow on the top of the shielding plate. This method cannot deal with the snow on the top of the shielding plate in time, which will cause the shielding plate to be damaged due to excessive weight when there is too much snow on the shielding plate, and it is easy to cause the distribution box to collapse. In addition, if the motor is started continuously to drive the shielding plate to shake, a large amount of electricity is consumed. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

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.

[0028] See also Figure 1-Figure 8One embodiment of the present invention is: a power distribution box protection device, comprising a shielding plate 1 and a distribution box shell 2, the shielding plate 1 is arranged on the top of the distribution box shell 2, a guide column 3 is fixed on the top of the distribution box shell 2, the shielding plate 1 is attached to the outer wall of the guide column 3, a fixing plate 5 is fixed on the inner side of the shielding plate 1, the guide column 3 penetrates the fixing plate 5, and the penetration is slidably connected, a connecting plate 4 is hinged on the inner side of the shielding plate 1, and a shaking component for clearing snow on the top of the shielding plate 1 is arranged on the distribution box shell 2; wherein, the shaking component The invention comprises a motor 6, an elastic switch 11, a moving block 7, a reset spring 8, a transmission block 9, a reciprocating screw rod 10, a bending block 12, an L-shaped connecting block 13, a connecting rod 14, a rotating column 15, a torsion spring 17, a protective plate 18, a rotating block 16, an L-shaped extrusion block 19 and a connecting rod 22; the motor 6 is fixed to the top of the distribution box housing 2, an elastic switch 11 is arranged on the front of the motor 6, and the elastic switch 11 is electrically connected to the motor 6, a reciprocating screw rod 10 is fixed to the top output end of the motor 6, the reciprocating screw rod 10 passes through the fixed plate 5, and is fixed The fixed plate 5 is slidably connected to the penetration point of the reciprocating screw rod 10, a moving block 7 is slidably installed on the top of the distribution box housing 2, a transmission block 9 is fixed to the side wall of the moving block 7, a connecting rod 22 is fixed to the top of the transmission block 9, and the top of the connecting rod 22 is slidably installed on the bottom of the fixed plate 5, a reset spring 8 is fixed on the side of the moving block 7 away from the motor 6, and the side of the reset spring 8 away from the moving block 7 is fixed to the top inner side of the distribution box housing 2, an L-shaped extrusion block 19 is fixed to the outer wall of the moving block 7, and a bending block 1 is slidably installed on the back of the distribution box housing 2 2, an L-shaped connecting block 13 is fixed to the side wall of the transmission block 9, a connecting rod 14 is fixed to the side wall of the L-shaped connecting block 13, an end point of the connecting rod 14 is slidably connected to the side wall of the bending block 12, a rotating column 15 is rotatably installed on the back of the distribution box housing 2, a protective plate 18 is fixed to the end point of the rotating column 15, a rotating block 16 is fixed to the outer wall of the rotating column 15, the inner side of the bending block 12 is fitted with the outer wall of the rotating block 16, a torsion spring 17 is fixed to the side wall of the rotating block 16, and the side of the torsion spring 17 away from the rotating block 16 is fixed to the outer wall of the distribution box housing 2.

[0029] Through the setting of the guide column 3, when the reciprocating screw 10 rotates on the fixed plate 5, the fixed plate 5 can drive the shielding plate 1 to move straight up and down; there are two groups of connecting plates 4, and the two groups of connecting plates 4 are symmetrically arranged with the center line of the shielding plate 1 in the vertical direction as the symmetry axis. When the connecting plates 4 are subjected to the pressure of accumulated snow, the connecting plates 4 will rotate at the hinge of the shielding plate 1, so that the connecting plates 4 will squeeze the transmission block 9. Through the cooperation of the moving block 7 and the L-shaped squeezing block 19, the motor 6 can be started to rotate the reciprocating screw 10, so that the shielding plate 1 can shake up and down back and forth, and the ice and snow accumulated on the top of the shielding plate 1 can be shaken and slide off.

[0030] Among them, two groups of protective plates 18 are arranged, and the two groups of protective plates 18 are symmetrically arranged with the center line of the shielding plate 1 in the vertical direction as the symmetry axis. By setting the protective plates 18, the heat dissipation holes on both sides of the distribution box can be shielded, so as to prevent the snow on the top of the shielding plate 1 from falling, and the snowflakes from drifting to the heat dissipation holes due to wind. When the snowflakes melt, the liquid can easily enter the distribution box casing 2 from the heat dissipation holes, causing damage to the electrical equipment.

[0031] When this embodiment is working: when encountering heavy snow weather, a large amount of snow will accumulate on the top of the shielding plate 1 and the connecting plate 4. When the connecting plate 4 is covered with snow, the connecting plate 4 will be subjected to an extrusion force, so that the connecting plate 4 will rotate toward the distribution box housing 2 at the hinge of the shielding plate 1, so that the connecting plate 4 can squeeze the transmission block 9, so that the transmission block 9 is close to the motor 6. When the transmission block 9 moves, it can drive the moving block 7 to move, so that the reset spring 8 is stretched. When the moving block 7 moves, the L-shaped extrusion block 19 will move, so that when the L-shaped extrusion block 19 moves to the inclined surface to squeeze the elastic switch 11 on the motor 6, the elastic switch 11 can be moved by the extrusion force, thereby starting the motor 6. When the motor 6 is started, the reciprocating screw 10 is rotated, thereby driving the fixed plate 5 to move back and forth on the reciprocating screw 10, and the fixed plate 5 can drive The shielding plate 1 and the connecting plate 4 move back and forth on the top of the distribution box housing 2, thereby driving the snow on the shielding plate 1 and the connecting plate 4 to shake back and forth, and the snow on the connecting plate 4 and the shielding plate 1 is removed, and when the snow on the connecting plate 4 slides down first, the snow on the shielding plate 1 will slide onto the connecting plate 4, so that when the snow on the shielding plate 1 completely slides onto the connecting plate 4, and then the snow on the connecting plate 4 is removed, the connecting plate 4 will not be subjected to the squeezing force, so that because the reset spring 8 is in a stretched state, it can drive the moving block 7 and the transmission block 9 to reset, so that the transmission block 9 can squeeze the connecting plate 4 to rotate and reset, and when the moving block 7 is reset, the L-shaped squeezing block 19 will not apply squeezing force to the elastic switch 11 on the motor 6, so that the elastic switch 11 can be reset, so that the motor 6 is turned off, thereby stopping the shielding plate 1 from reciprocating.

[0032] When the transmission block 9 approaches the motor 6, it will drive the L-shaped connecting block 13 to move, so that the L-shaped connecting block 13 will drive the connecting rod 14 to move, so that the connecting rod 14 pulls the bending block 12 to approach the motor 6. When the bending block 12 moves, the inner side of the bending block 12 will squeeze the rotating block 16, so that the rotating block 16 will rotate upward, so that the torsion spring 17 is compressed and deformed, and when the rotating block 16 rotates, the rotating column 15 can drive the protective plate 18 to rotate downward, so that the protective plate 1 8 blocks the heat dissipation holes on both sides of the distribution box housing 2, thereby preventing snowflakes from drifting to the heat dissipation holes, and when the transmission block 9 returns to its position, the bending block 12 is reset through the cooperation of the L-shaped connecting block 13 and the connecting rod 14, so that the bending block 12 will not squeeze the rotating block 16. Because the torsion spring 17 is in a compressed and deformed state, the torsion spring 17 can drive the rotating block 16 to rotate downward for reset, so that the rotating column 15 drives the protective plate 18 to rotate upward for reset, without blocking the heat dissipation holes on the side wall of the distribution box housing 2, and effective heat dissipation operation is performed.

[0033] See also Figure 1-Figure 8 On the basis of the above-mentioned embodiment, in another embodiment of the present invention, an auxiliary component for breaking the ice and snow condensed on the top of the shielding plate 1 is provided on the fixed plate 5, and also includes a deicing component, and the auxiliary component includes a triangular block 201, a connecting frame 202, a pointed cone 205, a connecting column 203, a connecting spring 204, a fixed block 207, a sliding rod 208 and a spiral groove 206; a triangular block 201 is fixed on the top of the transmission block 9, a connecting column 203 is penetrated in the fixed plate 5, and the penetration is slidably connected, a connecting frame 202 is fixed to the bottom of the connecting column 203, a pointed cone 205 is rotatably installed on the top of the connecting frame 202, the pointed cone 205 penetrates the top of the shielding plate 1, and the penetration is fitted, a spiral groove 206 is opened on the outer wall of the pointed cone 205, a fixed block 207 is fixed to the bottom of the shielding plate 1, a sliding rod 208 is fixed to the side wall of the fixed block 207, and the end point of the sliding rod 208 is fitted with the inner wall of the spiral groove 206.

[0034] By setting the pointed cone 205, when the bottom of the connecting frame 202 is squeezed by the inclined surface of the triangular block 201, the bottom of the connecting frame 202 will be moved upward by the squeezing force, thereby driving the pointed cone 205 out from the top of the shielding plate 1, so that the pointed cone 205 breaks the ice and snow condensed on the top of the shielding plate 1, preventing the ice and snow from solidifying and sticking to the top of the shielding plate 1, thereby making it inconvenient to remove the accumulated snow on the shielding plate 1.

[0035] By setting a spiral groove 206 on the outer wall of the pointed cone 205, when the spiral groove 206 squeezes the sliding rod 208, the pointed cone 205 can be rotated. When the pointed cone 205 breaks the ice and snow on the top of the shielding plate 1, the rotation of the pointed cone 205 can increase the impact force on the ice and snow, making the ice and snow easier to break, thereby improving the efficiency of ice and snow removal.

[0036] The de-icing assembly includes teeth 211, support columns 212, long plates 213, rotating rods 214, gears 215, belts 217, rotating rods 216 and striking blocks 218. The teeth 211 are fixed to the side walls of the connecting frame 202. The side walls of the fixed plates 5 are fixed with support columns 212. The end of the support columns 212 away from the fixed plates 5 is fixed with the long plates 213. The side of the long plates 213 close to the fixed plates 5 is rotatably mounted with the rotating rods 214. The outer wall of the rotating rods 214 is fixed with gears 215, which mesh with the teeth 211. The side walls of the long plates 213 are rotatably mounted with rotating rods 216. The end points of the rotating rods 216 are fixed with striking blocks 218. The outer walls of the rotating rods 216 and 214 are fixed with pulleys, and a belt 217 is wound around the two sets of pulleys.

[0037] By setting the striking block 218, when removing the snow on the shielding plate 1 and the connecting plate 4, the striking block 218 can be rotated, and the striking block 218 can knock down the icicles at the edge of the connecting plate 4 to prevent the icicles from condensing at the edge of the connecting plate 4, which may hinder the snow on the connecting plate 4 and affect the removal of the snow on the top of the shielding plate 1 and the connecting plate 4.

[0038] When the present embodiment is working, when the transmission block 9 approaches the motor 6, the inclined surface of the triangular block 201 on the top of the transmission block 9 squeezes the bottom of the connecting frame 202. When the bottom of the connecting frame 202 is squeezed, the connecting frame 202 moves upward. When the connecting frame 202 moves upward, the connecting column 203 can be driven to move upward, so that the connecting spring 204 is compressed. When the connecting frame 202 moves upward, the pointed cone 205 on the top of the connecting frame 202 is moved out from the top of the shielding plate 1, so as to break the ice and snow condensed on the top of the shielding plate 1, which is convenient for handling the accumulated snow. When the pointed cone 205 moves upward, the inner wall of the spiral groove 206 will squeeze the end point of the slide bar 208, and the spiral groove 206 will be driven by the squeezing force to drive the pointed cone 205 to rotate, so that the pointed cone 205 can also rotate while moving upward, which can increase the impact force on the ice and snow, making the ice and snow easier to break, and when the transmission block 9 is away from the motor 6 for reset, the triangular block 201 will not squeeze the connecting frame 202, because the connecting spring 204 is in a compressed state, it can drive the connecting frame 202 to move downward and return to its original position, so as to perform the next breaking operation.

[0039] When the connecting frame 202 moves upward, the teeth 211 on the side wall of the connecting frame 202 will move on the gear 215, so that the teeth 211 can drive the gear 215 to rotate, and the gear 215 can drive the rotating rod 214 to rotate. The pulley on the rotating rod 214 drives the belt 217 to transmit, so that the belt 217 can drive the pulley on the outer wall of the rotating rod 216 to rotate, so that the rotating rod 216 can drive the striking block 218 to rotate, so that the striking block 218 can strike the icicles at the edge of the connecting plate 4, and knock the icicles at the edge of the connecting plate 4 off.

[0040] 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.
