Description

Technical Field

[0001] The invention relates to the technical field of mobile power distribution cabinets, in particular to a mobile power distribution cabinet for a construction site. Background Art

[0002] A construction site, also known as a construction site in Cantonese, is a place where a construction project is being developed and civil engineering is being carried out. It is often enclosed by fences, wire mesh or walls to restrict the entry and exit of personnel, materials, machinery and vehicles. When working on a construction site, a distribution cabinet is usually used to supply power.

[0003] According to a mobile power distribution cabinet for construction sites (publication number: CN211958292U) disclosed in the above application, it includes a power distribution cabinet body, and mounting plates are provided at the four corners of the bottom of the power distribution cabinet body, and mounting bolts are threadedly connected at the four corners of the bottom of the mounting plate. The top of the mounting bolts penetrates into the inside of the power distribution cabinet body and is threadedly connected to the power distribution cabinet body. A fixed block is fixedly connected at the center of the bottom of the mounting plate, and a groove is provided inside the fixed block. The mobile power distribution cabinet for construction sites, through the design of the mounting plate and the mounting bolts, can facilitate the user to install the fixed block and the universal wheel to the bottom of the power distribution cabinet, so that the power distribution cabinet has the characteristics of mobility, and it is convenient for the user to transfer and move the power distribution cabinet. The design of the slide groove, the slide plate, the telescopic rod and the first damping pad can facilitate the power distribution cabinet to reduce shock and buffer the universal wheel when moving, which is convenient for the movement of the power distribution cabinet and improves the protection effect of the universal wheel.

[0004] In this patent, when the device is placed, the equipment is supported by locking the universal wheels. When the mobile distribution cabinet used in the construction site is placed outdoors and encounters heavy rain, the distribution cabinet may be impacted by excessive water on the ground. Since the universal wheels are relatively smooth, the distribution cabinet may be easily moved, affecting the normal use of the subsequent distribution cabinet, and in severe cases, the distribution cabinet may be tipped over and damaged, causing economic losses. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a mobile power distribution cabinet for a construction site, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mobile power distribution cabinet for a construction site, comprising a cabinet body, a universal wheel is fixed to the bottom of the cabinet body, a heat dissipation hole is opened on the side wall of the cabinet body, a placement plate is slidably installed on the inner wall of the cabinet body, an electrical device is fixed on the top of the placement plate, a support assembly for stably supporting the cabinet body is arranged on the cabinet body, and also includes a lifting assembly and a shielding assembly;

[0007] Among them, the supporting assembly includes a transmission column, a transmission plate, a transmission spring, an L-shaped extrusion plate, a connecting column, a connecting spring, a stabilizing plate, an oblique rod, a connecting rod, a push block, a limiting hole, a fixing block, an L-shaped sliding rod, a reset spring and a supporting plate; the transmission column is slidably installed on the bottom inner side of the cabinet, one end of the transmission column is fixed with a transmission spring, the other end of the transmission column is fixed with a transmission plate, the side of the transmission spring away from the transmission column is fixed to the bottom inner side of the cabinet, the bottom of the cabinet is penetrated by a connecting column, the bottom of the connecting column is fixed with a stabilizing plate, the bottom of the stabilizing plate is fixed with multiple groups of pointed cones in a linear array, the top of the stabilizing plate is fixed with a connecting spring, and the top of the connecting spring is fixed to the bottom of the cabinet. When encountering heavy rain, the rainwater on the ground impacts the transmission plate, which will cause the transmission plate to be subjected to force, so that the transmission column moves into the cabinet, so that the transmission plate can drive the L-shaped extrusion plate to move.

[0008] According to the above technical solution, a connecting rod passes through the bottom of the cabinet, and the connecting rod is slidably connected to the penetration point of the cabinet, a push block is fixed to the bottom of the connecting rod, and an inclined rod is slidably installed on the bottom of the inner wall of the cabinet, and the bottom inclined surface of the inclined rod is slidably connected to the top of the connecting rod, and a return spring is fixed to the top of the push block, and the top of the return spring is fixed to the bottom of the cabinet. When the L-shaped extrusion plate moves, the L-shaped extrusion plate can squeeze the inclined surface of the push block, so that the push block can drive the connecting rod to move upward, which will cause the connecting rod to squeeze the bottom of the inclined rod, so that the inclined rod can be forced away from the connecting column.

[0009] According to the above technical solution, a limiting hole is opened on the connecting column, and the inner wall of the limiting hole is fitted with the outer wall of the inclined rod. When the inclined rod is forced to move away from the connecting column, the inclined rod can be moved out of the limiting hole, and the limiting of the connecting column can be released. Since the connecting spring is in a compressed state, it can drive the stabilizing plate to move downward.

[0010] According to the above technical solution, a fixing block is fixed to the side wall of the stabilizing plate, and a supporting plate is hingedly connected to the side wall of the cabinet. An L-shaped sliding rod is fixed to the top of the fixing block, and the L-shaped sliding rod passes through the middle through hole of the supporting plate, and the through hole is fitted. When the stabilizing plate moves downward, the fixing block can drive the L-shaped sliding rod to move at the through hole in the middle of the supporting plate, so that the L-shaped sliding rod squeezes the through hole of the supporting plate, causing the support plate to flip.

[0011] According to the above technical scheme, the lifting assembly includes an L-shaped block, an L-shaped clamping rod, a return spring, a connecting plate, a U-shaped rod, an extrusion spring, an extrusion plate, an inclined groove and a clamping plate. The L-shaped block is fixed to the bottom of the placement plate, the L-shaped clamping rod is fixed to the top of the inclined rod, and a return spring is fixed to the bottom of the placement plate. The bottom of the return spring is fixed to the inner wall of the cabinet. When the inclined rod is away from the connecting column, the inclined rod can drive the L-shaped clamping rod to move out of the L-shaped block, thereby releasing the limit on the L-shaped block. Through the cooperation of the return spring, the placement plate can drive the electrical equipment to be lifted.

[0012] According to the above technical solution, a connecting plate is slidably installed in the placing plate, an inclined groove is provided on the connecting plate, and a pressing plate is fixed to the side wall of the connecting plate.

[0013] According to the above technical solution, a U-shaped rod passes through the placement plate, and the penetration point is slidably connected. The U-shaped rod passes through the inclined groove, and the U-shaped rod fits with the penetration point of the inclined groove. An extrusion plate is fixed to the bottom of the U-shaped rod, and an extrusion spring is fixed to the top of the extrusion plate. The top of the extrusion spring is fixed to the bottom of the placement plate. When the placement plate moves upward, the extrusion plate will not be subject to extrusion force. Since the extrusion spring is in a compressed state, it drives the U-shaped rod to move downward in the inclined groove, so that the connecting plate can drive the two sets of clamping plates to clamp the electrical equipment.

[0014] According to the above technical solution, the shielding assembly includes a pull rod, a hinge seat, a shielding plate, a rotating rod, a gear and a rack. The pull rod passes through the side wall of the cabinet and is slidably connected at the penetration point. One end of the pull rod is slidably installed on the side wall of the connecting plate, and the other end of the pull rod is fixed with a hinge seat. A rotating rod passes through the hinge seat, and the rotating rod is rotatably connected with the penetration point of the hinge seat. A shielding plate is fixed to the outer wall of the rotating rod, and a gear is fixed to the end point of the rotating rod. A rack is fixed to the side wall of the cabinet, and the rack and the gear are in mutual meshing state. When the connecting plate approaches the electrical equipment, the connecting plate can drive the pull rod to move, so that the pull rod can drive the hinge and the shielding plate to move, so that the gear moves on the rack, so that the shielding plate can be flipped to block the heat dissipation hole.

[0015] The present invention provides a mobile power distribution cabinet for construction sites, which has the following beneficial effects:

[0016] 1. The mobile power distribution cabinet used in the construction site, when heavy rain causes excessive ground water flow to impact the cabinet body, the transmission plate will be moved by the impact of the water flow, and the inclined surface of the push block can be squeezed by the L-shaped extrusion plate, so that the push block can drive the connecting rod to move upward, so that the inclined rod is squeezed away from the connecting column, so that the inclined rod is moved out of the limit hole, and the stabilizing plate is moved downward by the cooperation of the connecting spring, so that the pointed cone is in contact with the ground, thereby increasing the friction between the cabinet body and the ground, improving the stability of the equipment, and preventing the equipment from being displaced by the impact of the water flow, and when the stabilizing plate moves downward, the L-shaped slide bar will move at the middle through hole of the support plate, so that the L-shaped slide bar squeezes the support plate to flip to the side away from the cabinet body, so that the end point of the support plate is in contact with the ground, supporting the four sides of the cabinet body, and preventing the cabinet body from tipping over and causing damage due to excessive water flow.

[0017] 2. The mobile power distribution cabinet for construction sites can drive the L-shaped clamping rod to release the limit on the L-shaped clamping block when the inclined rod is away from the connecting column. Since the return spring is in a compressed state, the placement plate can drive the height of the electrical equipment to be raised to prevent the rainwater level on the ground from rising and causing the rainwater to contact the bottom of the electrical equipment and cause damage to the electrical equipment. When the placement plate moves upward, the U-shaped rod can move in the inclined groove through the cooperation of the extrusion spring, so that the connecting plate can drive the clamping plate to approach the electrical equipment, so that the clamping plate can clamp the electrical equipment, which can prevent the electrical equipment from shaking in the cabinet when the water flow impacts the distribution cabinet, thereby improving the stability of the electrical equipment.

[0018] 3. The construction site uses a mobile distribution cabinet, and when the connecting plate approaches the electrical equipment, the connecting plate will pull the pull rod, so that the hinged seat moves closer to the cabinet body, driving the gear to move on the rack, and the rotating rod drives the shielding plate to rotate to the side away from the cabinet body, so that the shielding plate can block the heat dissipation holes, which can prevent excessive rain from floating into the cabinet body through the heat dissipation holes and causing damage to the electrical equipment.

[0030] Eight support plates 18 are provided, and two support plates 18 form a group, and four groups of support plates 18 are arranged in a circular array with the center point of the connecting column 10, and the cabinet body is supported around by the support plates 18, thereby preventing the cabinet body 1 from tipping over.

[0031] When the present embodiment is working: when encountering torrential rain, a large amount of rainwater will accumulate on the road surface, and when the rainwater is too heavy, the rainwater on the road surface will impact the transmission plate 7, so that the transmission plate 7 which is subjected to the extrusion force will be moved closer to the cabinet 1, and the transmission column 6 will move toward the bottom of the cabinet 1, so that the transmission spring 8 will be compressed, and when the transmission plate 7 moves, the transmission plate 7 can drive the L-shaped extrusion plate 9 to move, so that the L-shaped extrusion plate 9 can squeeze the bottom inclined surface of the push block 14, so that the push block 14 will be subjected to the extrusion force and move upward, driving the connecting rod 13 to move upward, and when the push block 14 moves upward, the return spring 20 will be compressed, so that the top of the connecting rod 13 will squeeze the bottom of the inclined rod 15, so that the inclined rod 15 will be subjected to the extrusion force and move away from the connecting column 10, so that the end of the inclined rod 15 will move out of the limiting hole 16 of the connecting column 10, and the limiting of the connecting column 10 will be released. 2 is in a compressed state in its original state, so that the connecting spring 12 drives the stabilizing plate 11 to move downward, and the stabilizing plate 11 drives the pointed cone to move downward, so that the pointed cone can be inserted into the muddy ground on the construction site, thereby increasing the stability of the cabinet 1, and when the stabilizing plate 11 moves downward, the stabilizing plate 11 can drive the fixing block 17 to move downward, and the fixing block 17 drives the L-shaped slide bar 19 to move in the through hole opened in the middle of the supporting plate 18, so that the L-shaped slide bar 19 squeezes the middle of the supporting plate 18, and due to the squeezing force of the supporting plate 18, the supporting plate 18 is rotated to the side away from the cabinet 1, so that the supporting plate 18 can be rotated to contact the placement surface of the cabinet 1, and the four sides of the cabinet 1 can be supported by the supporting plate 18, thereby further improving the stability of the equipment and preventing the equipment from being subjected to excessive impact and causing a dumping situation.

[0032] When the cabinet 1 is not impacted by the ground water flow, the transmission plate 7 will not be squeezed, and the transmission spring 8 is in a compressed state, so that the transmission spring 8 can drive the transmission column 6 and the transmission plate 7 to reset, and the transmission plate 7 drives the L-shaped extrusion plate 9 not to squeeze the inclined surface at the bottom of the push block 14. Because the reset spring 20 is in a compressed state, the reset spring 20 will give the push block 14 a downward force, and the connecting rod 13 will pull the bottom of the inclined rod 15, so that the inclined rod 15 is against the outer wall of the connecting column 10, and when the stabilizing plate 11 needs to be reset, the connecting column 10 is moved upward, and when the connecting column 10 moves to the limit hole 16 and When the diagonal rod 15 is aligned, since the reset spring 20 is in a compressed state, the push block 14 can drive the connecting rod 13 to move downward, so that the diagonal rod 15 moves toward the connecting column 10 and extends into the limiting hole 16 of the connecting column 10, thereby resetting the connecting column 10, and when the connecting column 10 drives the stabilizing plate 11 to move upward, it can drive the fixing block 17 to move upward, so that the fixing block 17 drives the L-shaped slide bar 19 to move upward at the through hole in the middle of the support plate 18, so that the support plate 18 is flipped toward the cabinet body 1, and the support plate 18 is stored to prevent it from being in the unfolded state all the time and getting in the way, and making it inconvenient to move the mobile distribution cabinet.

[0033] See also Figure 1-Figure 8 On the basis of the above embodiment, another embodiment of the present invention further includes a lifting component and a shielding component, the lifting component includes an L-shaped block 211, an L-shaped card rod 212, a return spring 213, a connecting plate 216, a U-shaped rod 214, an extrusion spring 217, an extrusion plate 215, an inclined groove 218 and a clamping plate 219, the L-shaped block 211 is fixed to the bottom of the placement plate 4, the L-shaped card rod 212 is fixed to the top of the inclined rod 15, the bottom of the placement plate 4 is fixed with a return spring 213, the bottom of the return spring 213 is fixed to the inner wall of the cabinet 1, the placement plate 4 is slidably installed with a connecting plate 216, the connecting plate 216 is provided with an inclined groove 218, the side wall of the connecting plate 216 is fixed with a clamping plate 219, the placement plate 4 is penetrated by a U-shaped rod 214, and the penetration is slidably connected, the U-shaped The rod 214 passes through the inclined groove 218, and the U-shaped rod 214 fits with the penetration point of the inclined groove 218. A squeezing plate 215 is fixed to the bottom of the U-shaped rod 214. The bottom of the squeezing plate 215 fits with the bottom of the inner wall of the cabinet 1. A squeezing spring 217 is fixed to the top of the squeezing plate 215. The top of the squeezing spring 217 is fixed to the bottom of the placement plate 4. The L-shaped clamping rod 212 is removed from the L-shaped clamping block 211, so that the limit on the placement plate 4 can be released. Because the return spring 213 is in a compressed state, when the limit on the placement plate 4 is released, the return spring 213 can drive the placement plate 4 to move upward, so as to lift the electrical equipment 5 and keep the electrical equipment 5 away from the ground, so as to prevent excessive water accumulation on the ground, so that rainwater contacts the bottom of the electrical equipment 5 and causes damage to the electrical equipment 5.

[0034] There are two groups of clamping plates 219, and the two groups of clamping plates 219 are symmetrically arranged with the center line of the placement plate 4 in the vertical direction as the symmetry axis, and the clamping plates 219 are made of rubber. When the electrical equipment 5 is lifted by the placement plate 4, the clamping plates 219 can clamp both sides of the electrical equipment 5, thereby preventing the electrical equipment 5 in the cabinet 1 from shaking when the water flow impacts the cabinet 1.

[0035] The shielding assembly includes a pull rod 221, an articulated seat 222, a shielding plate 224, a rotating rod 223, a gear 226 and a rack 225. The pull rod 221 passes through the side wall of the cabinet 1 and is slidably connected at the penetration point. One end of the pull rod 221 is slidably mounted on the side wall of the connecting plate 216. The other end of the pull rod 221 is fixed with a hinge seat 222. The rotating rod 223 passes through the hinge seat 222, and the rotating rod 223 is rotatably connected to the penetration point of the hinge seat 222. The outer wall of the rotating rod 223 is fixed with a shielding plate. 224, a gear 226 is fixed to the end point of the rotating rod 223, and a rack 225 is fixed to the side wall of the cabinet 1. The rack 225 and the gear 226 are in meshing relationship with each other. Two groups of shielding plates 224 are arranged, and the two groups of shielding plates 224 are symmetrically arranged with the center line in the vertical direction of the cabinet 1 as the axis of symmetry. The shielding plates 224 can be used to obliquely shield the heat dissipation holes 2 on the side wall of the cabinet 1, thereby achieving the effect of keeping out rain and preventing excessive rain from floating into the cabinet 1 through the heat dissipation holes 2.

[0036] When the present embodiment is working, when the inclined rod 15 is away from the connecting column 10, the inclined rod 15 can drive the L-shaped clamping rod 212 to move away from the inner side of the L-shaped clamping block 211, so that the L-shaped clamping rod 212 does not contact the L-shaped clamping block 211. Because the L-shaped clamping rod 212 releases the limit of the L-shaped clamping block 211, and the return spring 213 is originally in a compressed state, the return spring 213 drives the placement plate 4 and the electrical equipment 5 to lift upward, to prevent excessive water accumulation on the road, so that rainwater contacts the bottom of the electrical equipment 5 and causes damage to the electrical equipment 5. When the placement plate 4 moves upward, the placement plate 4 drives the connecting plate 216 and the U-shaped rod 214 to move upward, and the extrusion plate 215 moves upward. When the extrusion plate 215 moves upward, the bottom of the extrusion plate 215 is not subject to the extrusion force, and because the extrusion spring 217 is in a compressed state, the extrusion spring 217 can squeeze the extrusion plate 215. The placement plate 4 moves downward, so that the extrusion plate 215 drives the U-shaped rod 214 to move downward, and the U-shaped rod 214 moves downward in the inclined groove 218 of the connecting plate 216, so that the U-shaped rod 214 squeezes the connecting plate 216 to approach the electrical equipment 5, and drives the two sets of clamping plates 219 to approach each other through the connecting plate 216, so that the clamping plate 219 clamps and fixes the electrical equipment 5, and when the connecting plate 216 approaches the connecting column 10, the connecting plate 216 drives the pull rod 221 to approach the connecting column 10, and the pull rod 221 drives the hinge seat 222 to approach the cabinet 1, so that the gear 226 moves on the rack 225, so that the gear 226 drives the rotating rod 223 to rotate, so that the rotating rod 223 drives the shielding plate 224 to flip in the direction away from the cabinet 1, and the shielding plate 224 rotates to a downward tilted state, which can play the effect of shielding the heat dissipation hole 2 from rain.

[0037] When the electrical equipment 5 needs to be adjusted to its original position, and when the inclined rod 15 is against the outer wall of the connecting column 10, the placement plate 4 is first pressed downward to move downward, thereby compressing the return spring 213. When the placement plate 4 drives the protrusion of the L-shaped block 211 to move to the bottom of the protrusion of the L-shaped clamping rod 212, and the connecting column 10 is moved upward, the inclined rod 15 extends into the limiting hole 16, and the inclined rod 15 can drive the protrusion of the L-shaped clamping rod 212 to move to the top of the protrusion of the L-shaped block 211, thereby limiting the placement plate 4 and returning the electrical equipment 5 to its original position, thereby facilitating the subsequent maintenance and wiring operations of the electrical equipment 5. When the placement plate 4 moves downward, the bottom of the extrusion plate 215 will contact the bottom of the inner wall of the cabinet 1, and when the placement plate 4 continues to move downward, the U-shaped rod 2 14 moves upward in the placement plate 4, compressing the extrusion spring 217, and when the U-shaped rod 214 moves upward in the inclined groove 218, it can squeeze the connecting plate 216 away from the connecting column 10, drive the clamping plate 219 away from the electrical equipment 5, and stop squeezing the electrical equipment 5, preventing the clamping plate 219 from squeezing the electrical equipment 5 all the time, which may cause structural deformation or damage to the electrical equipment 5, and when the connecting plate 216 is away from the connecting column 10, the connecting plate 216 can squeeze the pull rod 221 to move outside the cabinet 1, so that the hinge seat 222 is away from the cabinet 1, and the gear 226 is away from the cabinet 1 on the rack 225, so that the rotating rod 223 can drive the shielding plate 224 to flip upward, so that the shielding plate 224 is flush with the cabinet 1, and the shielding plate 224 is stored to prevent it from being in the unfolded state all the time, which is quite troublesome.

[0038] 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.
