Description

Technical Field

[0001] The present invention relates to the technical field of distribution box devices, and particularly relates to an installation structure of a distribution box. Background Art

[0002] The distribution box is an electrical equipment, which has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, widespread application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. In the early stage, the installation of the distribution box mostly adopted simple wall fixing or bracket supporting structures, relying on rigid connection methods such as bolts and angle steels.

[0003] The installation structure of the distribution box in the prior art is in the form of a clamp. During use, if there are some particulate impurities such as dust between the clamp and the surface of the rod body, it will hinder the direct contact between the clamp and the rod body, making it easy for the two to become loose. In rainy weather, due to the erosion and scouring of rainwater, there will be rainwater residue at the clamp gap, which cannot be discharged in time, causing rust damage to the clamp, reducing its structural strength and installation stability.

[0004] For example, the invention patent with the publication number CN117613718B provides an installation structure of a distribution box and a distribution box. When fixing and installing the distribution box, a certain adjustment margin is reserved, so that the distribution box can rotate in place and move back and forth to meet the adjustment and maintenance requirements. However, in the outdoor hot and cold alternating environment, the installation structure of this distribution box will cause the clamping force between the installation structure and the rod body to fluctuate due to temperature changes, which will in turn cause loosening or stress overload. In severe cases, it may damage the structure or the rod body. And under the action of strong wind, the distribution box will generate an instantaneous torque relative to the rod body, which will cause loosening between the distribution box and the rod body. Summary of the Invention

[0005] The present invention provides an installation structure of a distribution box to solve the problems that the existing installation structure of the distribution box and the rod body are prone to looseness, and the stability of the connection between the installation structure of the distribution box and the rod body is insufficient.

Then, the adjustment box is rotated. The adjustment box drives the clamp to rotate forward first and move downward, and then rotate backward and move upward. The clamp drives the friction belt to move, so that the friction belt changes from the first state to the second state. During the movement of the friction belt, the dust on the column is cleaned, avoiding the influence of dust particles and impurities on the connection between the clamp and the column, and making the connection between the clamp and the column more stable.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0028] Referring to Figures 1 to 11 As shown, a distribution box installation structure provided by an embodiment of the present invention is used to install a power distribution cabinet 110 on a vertically arranged column 120, and includes an adjustment box, an adjustment mechanism, a cleaning mechanism, and two installation mechanisms. The adjustment box is arranged on the power distribution cabinet 110, and vertical first channels 280 are respectively opened on the upper and lower sides of the adjustment box.

[0029] The two installation mechanisms are respectively arranged on the upper and lower sides of the adjustment box. Each installation mechanism includes a top rod 223, a tightening block 222, and a clamp 220. The top rod 223 is vertically arranged, and each top rod 223 is slidably arranged up and down in a first channel 280. The tightening block 222 is fixedly arranged on the adjustment box. The clamp 220 is spiral, the clamp 220 is wound around the column 120, one end of the clamp 220 is arranged on the tightening block 222, and the other end of the clamp 220 is fixedly connected to the top rod 223. The adjustment mechanism drives the top rod 223 to slide up and down. The more the top rod 223 extends out of the adjustment box, the tighter the clamp 220 clamps the column 120.

[0030] The cleaning mechanism includes two friction belts 224. The friction belts 224 are arranged along the spiral extension direction of the clamp 220, and the friction belts 224 are fixedly connected to the lower side edges of each turn of the clamp 220. Along the radial direction of the column 120, the two sides of the friction belt 224 are respectively a friction side and a smooth side. The friction belt 224 has a first state and a second state. The first state of the friction belt 224 is that the friction belt 224 is between the column 120 and the clamp 220, and the friction side is in contact with the column 120. The second state of the friction belt 224 is that the friction belt 224 is on the lower side of each turn of the clamp 220, and the smooth side of the friction belt 224 is in contact with the column 120. The clamp 220 first rotates forward and moves downward, and then rotates backward and moves upward. The clamp 220 drives the friction belt 224 to move, so that the friction belt 224 changes from the first state to the second state.

[0031] As Figure 6 shown, the forward rotation of the clamp 220 is counterclockwise rotation, and the reverse rotation of the clamp 220 is clockwise rotation.

[0032] Place the power distribution cabinet 110 at the target position and wind two clamps 220 around the column 120. The spiral-shaped clamp 220 can adapt to columns 120 with different diameters, and its applicability is stronger. Since the clamp 220 is spiral-shaped, rainwater will flow along the spiral-shaped clamp 220, so that less rainwater remains on the clamp 220, preventing the clamp 220 from being corroded and damaged due to the failure to drain rainwater in time, and reducing its structural strength and installation stability.

[0033] In the initial state, the friction belt 224 is in the first state. The friction belt 224 is located between the column 120 and the clamp 220, and the friction side of the friction belt 224 contacts the column 120. Then rotate the adjustment box. The adjustment box drives the clamp 220 to rotate forward and move downward first, and then rotate backward and move upward. The clamp 220 drives the friction belt 224 to move, so that the friction belt 224 changes from the first state to the second state. During the movement of the friction belt 224, the dust on the column 120 is cleaned, avoiding the influence of dust particles and impurities on the connection between the clamp 220 and the column 120.

[0034] In this embodiment, a first chute is formed in the tightening block 222, and the first chute is horizontally arranged. Each mounting mechanism further includes a screw rod 221, the screw rod 221 is horizontally arranged, and each screw rod 221 is rotatably arranged in the first chute. A plurality of card slots 225 are formed in the clamp 220, and the plurality of card slots 225 are sequentially distributed along the spiral extension direction of the clamp 220. One end of the clamp 220 is slidably arranged in the first chute, and the screw rod 221 and the card slot 225 are in spiral transmission cooperation. When the screw rod 221 rotates, the clamp 220 moves along the first chute.

[0035] After winding two clamps 220 around the column 120, due to the spiral cooperation between the screw rod 221 and the card slot 225, rotate the screw rod 221 to make the clamp 220 move towards the inside of the first chute, and perform preliminary pre-tightening on the clamp 220, thereby connecting the clamp 220 and the column 120.

[0036] In this embodiment, along the up and down direction, the two sides of the friction belt 224 are the first side and the second side respectively, and the side where the friction belt 224 is fixedly connected to the clamp 220 is the first side. When the friction belt 224 is in the first state, the second side of each turn of the friction belt 224 is above the first side of the friction belt 224, and the second side of each turn of the friction belt 224 is flush with the upper side edge of each turn of the clamp 220. When the friction belt 224 is in the second state, the second side of each turn of the friction belt 224 is below the first side of the friction belt 224, and at this time the clamp 220 contacts the column 120.

[0037] In the initial state, the friction belt 224 is in the first state. The friction belt 224 is located between the column 120 and the clamp 220. The friction side contacts the column 120, and for each turn of the friction belt 224, the second side is above the first side of the friction belt 224, and the second side of the friction belt 224 is flush with the upper side edge of each turn of the clamp 220.

[0038] After that, rotate the adjustment box, and the adjustment box drives the clamp 220 to rotate forward first and move downward. Since the first side of the friction belt 224 is fixedly connected to the clamp 220. Therefore, when the clamp 220 moves downward, it drives the friction belt 224 to move downward synchronously to clean the surface of the column 120. Then rotate the clamp 220 in the reverse direction, and the clamp 220 moves upward. Since the friction side of the friction belt 224 contacts the column 120 and the friction belt 224 is in frictional contact with the column 120, when the clamp 220 moves upward at this time, the clamp 220 drives the first side of the friction belt 224 to move upward, while the second side of the friction belt 224 does not move at this time. The clamp 220 continuously moves upward and continuously drives the first side of the friction belt 224 to move upward until the smooth side of the friction belt 224 contacts the column 120, the first side of the friction belt 224 is above the second side of the friction belt 224, and the friction belt 224 is located on the lower side of each turn of the clamp 220.

[0039] In this embodiment, the adjustment box includes a first connection box 230, a second connection box 240, a third connection box 250, and a fourth connection box 260. The first connection box 230, the second connection box 240, the third connection box 250, and the fourth connection box 260 are sequentially distributed along the direction from top to bottom. Two first channels 280 are respectively located in the first connection box 230 and the fourth connection box 260. Second channels 281 are provided in both the second connection box 240 and the third connection box 250, and the second channels 281 are vertically arranged. The second channel 281 in the second connection box 240 is communicated with the first channel 280 in the first connection box 230. The second channel 281 in the third connection box 250 is communicated with the first channel 280 in the fourth connection box 260. After each first channel 280 is communicated with a second channel 281, a first installation channel is formed.

[0040] Each installation mechanism further includes a piston cylinder 271 and a hydraulic piston rod 272. The piston cylinder 271 and the hydraulic piston rod 272 are both vertically arranged. The piston cylinder 271 is detachably arranged in the first installation channel, and the piston cylinder 271 is communicated with the second channel 281. One end of each hydraulic piston rod 272 is slidably arranged in a piston cylinder 271, and the other end of each hydraulic piston rod 272 is detachably connected to the ejector rod 223.

[0041] In this embodiment, an empty slot is provided in the first connection box 230, and the empty slot is vertically arranged. An installation hydraulic oil cavity 241 and a first oil pipeline 242 are provided in the second connection box 240. Hydraulic oil is arranged in the installation hydraulic oil cavity 241, and the installation hydraulic oil cavity 241 is respectively communicated with the empty slot and the first oil pipeline 242. The first oil pipeline 242 is communicated with two second channels 281.

[0042] The adjusting mechanism includes a first adjusting component. The first adjusting component includes a screw rod 232. The screw rod 232 is vertically arranged, rotatably arranged in the empty slot, and in screw fit with the empty slot. A first piston is fixedly arranged at the lower end of the screw rod 232, and the first piston is slidably arranged in the installation hydraulic oil cavity 241.

[0043] Rotate the screw rod 232 to make the screw rod 232 move downward. The screw rod 232 drives the first piston to move downward synchronously, thereby squeezing the hydraulic oil in the installation hydraulic oil cavity 241. The hydraulic oil in the installation hydraulic oil cavity 241 enters the two second channels 281 respectively through the first oil pipeline 242, and then enters the two piston cylinders 271, thereby pushing the hydraulic piston rod 272 to move away from the piston cylinder 271 where it is located. The hydraulic piston rod 272 drives the ejector rod 223 to move outside the adjusting box, so that the clamp 220 and the column 120 are further clamped.

[0044] In this embodiment, third channels 282 are provided in both the second connection box 240 and the third connection box 250. The two third channels 282 are communicated with each other. The second channel 281 on the second connection box 240 is communicated with the third channel 282 on the second connection box 240, and the second channel 281 on the third connection box 250 is communicated with the third channel 282 on the third connection box 250. A baffle 284 is fixedly arranged in each third channel 282, and a first through hole is provided in each baffle 284.

[0045] The adjusting mechanism further includes a second adjusting component. The second adjusting component includes two sliding blocks. Each sliding block is slidably arranged up and down in a first through hole. Second pistons 245 and third pistons 246 are respectively fixedly arranged at both ends of each sliding block along the up and down direction. The second piston 245 is located on the side of the sliding block away from the adjacent sliding block, and the third piston 246 is located on the side of the sliding block close to the adjacent sliding block. The baffle 284 and the third piston 246 form a cavity 285 with variable space size in the third channel 282, and a thermally expandable material is arranged in the cavity 285.

[0046] During use, when the temperature rises, the thermally sensitive expansion material in the cavity 285 expands, and the thermally sensitive expansion materials in the two cavities 285 push the two third pistons 246 closer to each other. Therefore, the second piston 245 moves away from the second channel 281, generating a negative pressure on the second channel 281. Furthermore, the hydraulic piston rod 272 drives the ejector rod 223 to move towards the inside of the adjustment box, thereby reducing the clamping force between the clamp 220 and the upright column 120 to maintain the clamping force between the clamp 220 and the upright column 120. To prevent the connection between the clamp 220 and the upright column 120 from becoming tighter due to thermal expansion, thus damaging the upright column 120 and the clamp 220.

[0047] When the temperature drops, the thermally sensitive expansion material contracts and drives the two third pistons 246 away from each other. Furthermore, the hydraulic piston rod 272 drives the ejector rod 223 to move towards the outside of the adjustment box, thereby increasing the clamping force between the clamp 220 and the upright column 120 to maintain the clamping force between the clamp 220 and the upright column 120. To prevent the connection between the clamp 220 and the upright column 120 from becoming loose due to cold shrinkage.

[0048] In this embodiment, a mating box 210 is fixedly arranged on the second connection box 240. A fourth channel is provided in the mating box 210, and the fourth channel is arranged vertically. A risk control hydraulic oil cavity 248 and a second oil pipeline 247 are provided on the second connection box 240. Hydraulic oil is arranged in the risk control hydraulic oil cavity 248. The risk control hydraulic oil cavity 248 communicates with the fourth channel and the second oil pipeline 247, and the second oil pipeline 247 communicates with the two second channels 281.

[0049] The adjustment mechanism further includes a third adjustment assembly. The third adjustment assembly includes a risk control piston rod 213. The risk control piston rod 213 is arranged vertically and is slidably arranged up and down in the fourth channel. A fourth piston is fixedly arranged at the lower end of the risk control piston rod 213, and the fourth piston is arranged in the risk control hydraulic oil cavity 248.

[0050] In this embodiment, the third adjustment assembly further includes an adjustment block 214. The adjustment block 214 is fixedly connected to the risk control piston rod 213, and the adjustment block 214 is located outside the mating box 210. A triangular wedge-shaped hole 212 is provided in the adjustment block 214. The triangular wedge-shaped hole 212 includes two inclined surfaces, and the two inclined surfaces gradually approach along the direction from top to bottom. A triangular fixing block 111 is fixedly arranged on the power distribution cabinet 110, and the triangular fixing block 111 is arranged in the triangular wedge-shaped hole 212, and the triangular fixing block 111 and the triangular wedge-shaped hole 212 cooperate with each other.

[0051] In this embodiment, a plurality of connecting blocks 234 are fixedly arranged on the adjusting box, and the plurality of connecting blocks 234 are sequentially distributed along the circumferential direction of the adjusting box. Each connecting block 234 is provided with a connecting sliding groove 233, and the connecting sliding groove 233 is arranged along a first direction. The first direction is the horizontal direction and is the length direction of the power distribution cabinet 110. A first screw 235 is arranged in each connecting sliding groove 233, and the first screw 235 can slide along the first direction. The first screw 235 connects the power distribution cabinet 110 and the connecting block 234.

[0052] In a windy state, a torque will be generated between the power distribution cabinet 110 and the adjusting box, so that displacement occurs between the power distribution cabinet 110 and the adjusting box. Since the triangular fixing block 111 is arranged in the triangular wedge-shaped hole 212, when displacement occurs between the power distribution cabinet 110 and the adjusting box, the triangular fixing block 111 presses the adjusting block 214, causing the adjusting block 214 to move downward. The adjusting block 214 drives the air control piston rod 213 to move downward, and the air control piston rod 213 drives the fourth piston to move downward. The fourth piston presses the hydraulic oil in the air control hydraulic oil chamber 248, and the hydraulic oil in the air control hydraulic oil chamber 248 is pressed into the two second channels 281 through the second oil pipe 247. The hydraulic piston rod 272 drives the ejector rod 223 to move outside the adjusting box, so that the clamp 220 and the column 120 are further clamped.

[0053] In this embodiment, the first connection box 230 and the second connection box 240, the second connection box 240 and the third connection box 250, and the third connection box 250 and the fourth connection box 260 are all fixedly connected by second screws.

[0054] Working process: Connect the power distribution cabinet 110 and the connecting block 234 through the first screw 235. Then place the power distribution cabinet 110 at the target position and wind the two clamps 220 around the column 120. Since the screw rod 221 and the card slot 225 are in a spiral fit, rotating the screw rod 221 causes the clamp 220 to move towards the inside of the first sliding groove, preliminarily pre-tightening the clamp 220, and then connecting the clamp 220 and the column 120. The spiral-shaped clamp 220 can adapt to columns 120 with different diameters, and its applicability is stronger.

[0055] In the initial state, the friction belt 224 is in a first state. The friction belt 224 is between the column 120 and the clamp 220. The friction side is in contact with the column 120, and the second side of each turn of the friction belt 224 is below the first side of the friction belt 224, and the second side of the friction belt 224 is flush with the upper side edge of each turn of the clamp 220.

[0056] After that, rotate the adjusting box, and the adjusting box drives the clamp 220 to rotate forward first. As Figure 7As shown, when the clamp 220 rotates forward, that is, the clamp 220 rotates counterclockwise and moves downward along the tangent of the clamp 220. When the clamp 220 rotates backward, that is, the clamp 220 rotates clockwise and moves upward along the tangent of the clamp 220.

[0057] As Figure 11 shown, since the first side of the friction belt 224 is fixedly connected to the clamp 220. Therefore, when the clamp 220 moves downward, it drives the friction belt 224 to move downward synchronously, cleaning the surface of the upright column 120. Then, the clamp 220 is rotated backward, and the clamp 220 moves upward. Since the friction side of the friction belt 224 contacts the upright column 120 and the friction belt 224 and the upright column 120 are in frictional contact, when the clamp 220 moves upward at this time, the clamp 220 drives the first side of the friction belt 224 to move upward, while the second side of the friction belt 224 does not move at this time. The clamp 220 continuously moves upward and continuously drives the first side of the friction belt 224 to move upward until the smooth side of the friction belt 224 contacts the upright column 120, the first side of the friction belt 224 is above the second side of the friction belt 224, and the friction belt 224 is on the lower side of each turn of the clamp 220. The friction belt 224 cleans the dust on the upright column 120 during the moving process, avoiding the influence of dust particles and impurities on the connection between the clamp 220 and the upright column 120.

[0058] Finally, the screw rod 232 is rotated so that the screw rod 232 moves downward. The screw rod 232 drives the first piston to move downward synchronously, thereby squeezing the hydraulic oil in the installation hydraulic oil cavity 241. The hydraulic oil in the installation hydraulic oil cavity 241 enters the two second channels 281 through the first oil pipeline 242 respectively, and then enters the two piston cylinders 271, thereby pushing the hydraulic piston rod 272 to move in the direction away from the piston cylinder 271 where it is located. The hydraulic piston rod 272 drives the ejector rod 223 to move outside the adjustment box. The ejector rod 223 drives the clamp 220 to move, so that the length of the clamp 220 along the axial direction of the upright column 120 increases, and the pitch of the clamp 220 increases. Since one end of the clamp 220 is connected to the tightening block 222, when the pitch of the clamp 220 increases, the clamp 220 and the upright column 120 are further clamped. At this time, the installation of a distribution box installation structure is completed.

[0059] Since the clamp 220 is spiral, rainwater will flow along the spiral clamp 220, so that less rainwater remains on the clamp 220, preventing the clamp 220 from being corroded and damaged due to the failure to drain rainwater in time, and reducing its structural strength and installation stability.

[0060] During use, when the temperature rises, the thermally sensitive expansion material in the cavity 285 expands. The thermally sensitive expansion materials in the two cavities 285 push the two third pistons 246 closer to each other. Therefore, the second piston 245 moves away from the second channel 281, generating a negative pressure on the second channel 281. Furthermore, the hydraulic piston rod 272 drives the ejector rod 223 to move towards the inside of the adjustment box, thereby reducing the clamping force between the clamp 220 and the column 120 to maintain the clamping force between the clamp 220 and the column 120. This is to prevent the connection between the clamp 220 and the column 120 from becoming tighter due to thermal expansion, thus damaging the column 120 and the clamp 220.

[0061] When the temperature drops, the thermally sensitive expansion material contracts and drives the two third pistons 246 away from each other. Furthermore, the hydraulic piston rod 272 drives the ejector rod 223 to move towards the outside of the adjustment box, thereby increasing the clamping force between the clamp 220 and the column 120 to maintain the clamping force between the clamp 220 and the column 120. This is to prevent the connection between the clamp 220 and the column 120 from becoming loose due to cold shrinkage.

[0062] In a windy state, a torque will be generated between the power distribution cabinet 110 and the adjustment box, causing displacement between the power distribution cabinet 110 and the adjustment box. Since the triangular fixing block 111 is arranged in the triangular wedge-shaped hole 212, when displacement occurs between the power distribution cabinet 110 and the adjustment box, the triangular fixing block 111 squeezes the adjustment block 214, causing the adjustment block 214 to move downward. The adjustment block 214 drives the wind control piston rod 213 to move downward, and the wind control piston rod 213 drives the fourth piston to move downward. The fourth piston squeezes the hydraulic oil in the wind control hydraulic oil cavity 248, and the hydraulic oil in the wind control hydraulic oil cavity 248 is pressed into the two second channels 281 through the second oil pipeline 247. The hydraulic piston rod 272 drives the ejector rod 223 to move towards the outside of the adjustment box, making the clamp 220 and the column 120 clamp more tightly. It can ensure that the greater the torque brought by the wind to the power distribution cabinet 110, the greater the clamping force between the clamp 220 and the column 120, effectively preventing the risk of loosening between the clamp 220 and the column 120.

[0063] When the installation of an installation structure of a distribution box is completed, the clamping force between the clamp 220 and the column 120 is the target clamping force.

[0064] According to the different materials of the column 120, replace the piston cylinders 271 and the hydraulic piston rods 272 with different inner diameters. For example, when the column 120 is made of relatively soft materials such as wood or relatively hard materials such as metal. The thermal expansion coefficient of the column 120 made of metal is greater than that of the column 120 made of wood. When the column 120 made of metal expands after heating, the clamping force increases more, and when the column 120 made of wood expands after heating, the clamping force increases less.

[0065] Under the same temperature environment, since the thermally sensitive expansion material remains unchanged, the thrust of the second adjusting component on the hydraulic piston rod 272 is a fixed value. Therefore, when the column 120 is made of wood, the inner diameter of the piston cylinder 271 is relatively large. Thus, when the thrust of the second adjusting component on the hydraulic piston rod 272 is constant, the hydraulic piston rod 272 and the ejector rod 223 move less, and the reduced clamping force between the clamp 220 and the wooden column 120 is relatively small, so as to adapt to the relatively small increased clamping force after the wooden column 120 expands when heated, and keep the clamping force between the clamp 220 and the column 120 at the target clamping force.

[0066] When the column 120 is made of metal, the inner diameter of the piston cylinder 271 is relatively small, the ejector rod 223 moves more, and the reduced clamping force between the clamp 220 and the metal column 120 is relatively large, so as to adapt to the relatively large increased clamping force after the metal column 120 expands when heated, and keep the clamping force between the clamp 220 and the column 120 at the target clamping force.

[0067] Prevent the clamping force between the clamp 220 and the column 120 from being too large to damage the clamp 220 and the column 120, and prevent the clamping force between the clamp 220 and the column 120 from being too small to cause looseness.

[0068] By changing the inclination angle of the inclined surface of the triangular wedge-shaped hole 212 and the angle of the triangular fixing block 111 that cooperates with the triangular wedge-shaped hole 212. When the column 120 is made of wood, at this time the inner diameter of the piston cylinder 271 is relatively large. By changing the inclination angle of the inclined surface, the included angle between the two inclined surfaces becomes smaller, and the more the adjusting block 214 drives the risk control piston rod 213 to move downward, the more hydraulic oil in the risk control hydraulic oil chamber 248 is pushed into the second channel 281 through the second oil pipeline 247 by the risk control piston rod 213. Furthermore, the hydraulic piston rod 272 maintains the same elongation, so that the clamping force between the clamp 220 and the column 120 remains consistent.

[0069] When the column 120 is made of metal, at this time the inner diameter of the piston cylinder 271 is relatively small, the included angle between the two inclined surfaces is larger, the adjusting block 214 drives the risk control piston rod 213 to move downward less, and the less hydraulic oil in the risk control hydraulic oil chamber 248 is pushed into the second channel 281 through the second oil pipeline 247 by the risk control piston rod 213. Furthermore, the hydraulic piston rod 272 maintains the same elongation, so that the clamping force between the clamp 220 and the column 120 remains consistent.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
