Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of distribution box devices, and in particular to a distribution box installation structure. Background Art
[0002] Distribution boxes are electrical equipment characterized by their small size, ease of installation, exceptional technical performance, fixed location, unique configuration features, and site-independent functionality. They are widely used, offer stable and reliable operation, high space utilization, minimal footprint, and environmentally friendly features. Early distribution box installations often employed simple wall-mounted or bracket-supported structures, relying on rigid connections such as bolts and angle steel.
[0003] Conventional distribution box mounting structures utilize clamps. During use, dust and other particulate matter between the clamp and the rod surface can hinder direct contact between the clamp and the rod, making them susceptible to loosening. Rainwater erosion and scouring can also cause residual water to accumulate in the clamp's crevices, preventing it from draining out promptly. This can lead to corrosion and damage to the clamp, reducing its structural strength and installation stability.
[0004] For example, patent publication CN117613718B provides a distribution box mounting structure and distribution box. This allows for a certain amount of adjustment during the fixing and installation of the distribution box, allowing it to rotate in place and move forward and backward to meet adjustment and maintenance needs. However, in outdoor environments with alternating hot and cold temperatures, this distribution box installation structure can experience temperature fluctuations, causing the clamping force between the mounting structure and the pole to fluctuate, leading to loosening or stress overload, which in severe cases may damage the structure or the pole. Furthermore, under strong winds, the distribution box can generate instantaneous torque relative to the pole, which can cause loosening between the distribution box and the pole. Summary of the Invention
[0005] The present invention provides a distribution box installation structure to solve the problems of easy looseness between the existing distribution box installation structure and the rod body and insufficient stability of the connection between the distribution box installation structure and the rod body.
[0006] The present invention provides a distribution box mounting structure employing the following technical solution: a distribution box mounting structure for mounting the distribution box on a vertically disposed column, comprising an adjustment box, an adjustment mechanism, a cleaning mechanism, and two mounting mechanisms. The adjustment box is mounted on the distribution box, and a first channel is defined on the upper and lower sides of the adjustment box.
[0007] Two mounting mechanisms are located on the upper and lower sides of the adjustment box. Each mounting mechanism includes a push rod, a tightening block, and a clamp. The push rods are vertically mounted and slide up and down within a first channel. The tightening block is mounted on the adjustment box. The clamp is spirally wound around the column, with one end of the clamp attached to the tightening block and the other end connected to the push rod. The adjustment mechanism drives the push rods to move; the further the push rods extend out of the adjustment box, the tighter the clamp grips the column.
[0008] The cleaning mechanism includes two friction belts arranged along the spiral extension of the clamp. Each friction belt is fixedly connected to the lower side of each loop of the clamp. Along the radial direction of the column, the friction belt has a friction side and a smooth side. The friction belt has a first state and a second state. In the first state, the friction belt is positioned between the column and the clamp, with the friction side in contact with the column. In the second state, the smooth side of the friction belt is in contact with the column. The clamp first rotates forward and moves downward, then rotates backward and moves upward. The clamp drives the friction belt, causing the friction belt to transition from the first state to the second state.
[0009] Furthermore, the tightening block is provided with a first horizontally disposed chute. Each mounting mechanism also includes a horizontally disposed spiral rod, each of which is rotatably disposed within the first chute. The clamp is provided with multiple slots, which are sequentially distributed along the direction of the clamp's spiral extension. One end of the clamp is slidably disposed within the first chute, with the spiral rod and the slot engaging in a helical transmission. When the spiral rod rotates, the clamp moves along the first chute.
[0010] Furthermore, along the vertical direction, the friction band has a first side and a second side, respectively. The side where the friction band and the clamp are fixedly connected is the first side. When the friction band is in the first state, the second side of each friction band loop is above the first side of the friction band, and the second side of each friction band loop is flush with the upper side of each clamp loop. When the friction band is in the second state, the second side of each friction band loop is below the first side of the friction band, and the clamp is in contact with the column.
[0011] Furthermore, the regulating box includes a first connection box, a second connection box, a third connection box, and a fourth connection box. The first connection box, the second connection box, the third connection box, and the fourth connection box are arranged in order from top to bottom. Two first channels are located in the first connection box and the fourth connection box, respectively. The second connection box and the third connection box are each provided with a second channel, which is arranged vertically. The second channel in the second connection box is connected to the first channel in the first connection box. The second channel in the third connection box is connected to the first channel in the fourth connection box. Each first channel is connected to a second channel to form a first installation channel.
[0012] Each mounting mechanism also includes a piston cylinder and a hydraulic piston rod, both of which are vertically arranged. The piston cylinder is removably mounted within the first mounting channel and communicates with the second channel. One end of each hydraulic piston rod is slidably mounted within a piston cylinder, and the other end of each hydraulic piston rod is removably connected to a push rod.
[0013] Furthermore, a vertically disposed slot is defined within the first connection box. A hydraulic oil chamber and a first oil pipeline are defined within the second connection box. Hydraulic oil is contained within the hydraulic oil chamber, which is in communication with the slot and the first oil pipeline, respectively. The first oil pipeline is in communication with the two second channels.
[0014] The adjustment mechanism includes a first adjustment component, which includes a screw rod, which is vertically arranged and rotatably arranged in an empty groove and spirally engaged with the empty groove. A first piston is fixedly arranged at the lower end of the screw rod, and the first piston is slidably arranged in an installation hydraulic oil chamber.
[0015] Furthermore, a third channel is defined within each of the second and third connection boxes. The two third channels are interconnected, the second channel on the second connection box is interconnected with the third channel on the second connection box, and the second channel on the third connection box is interconnected with the third channel on the third connection box. A baffle is fixedly disposed within each third channel, and each baffle has a first through hole.
[0016] The adjustment mechanism also includes a second adjustment assembly comprising two sliding blocks, each of which is slidably disposed vertically within a first through-hole. A second piston and a third piston are fixedly disposed at each end of each sliding block, respectively, along the vertical direction. The second piston is located on the side of the sliding block facing away from the adjacent sliding block, while the third piston is located on the side of the sliding block facing closer to the adjacent sliding block. The baffle and the third piston form a variable-sized cavity within the third channel, which is filled with a thermally sensitive expansion material.
[0017] Furthermore, a matching box is fixedly mounted on the second connection box, and a fourth channel is defined in the matching box. The fourth channel is vertically arranged. The second connection box is provided with a wind-controlled hydraulic oil chamber and a second oil pipeline. Hydraulic oil is provided in the wind-controlled hydraulic oil chamber, which communicates with the fourth channel and the second oil pipeline. The second oil pipeline is connected to the two second channels.
[0018] The adjustment mechanism also includes a third adjustment component, which includes a wind control piston rod. The wind control piston rod is vertically arranged and slidably arranged in the fourth channel. The lower end of the wind control piston rod is fixed with a fourth piston, and the fourth piston is arranged in the wind control hydraulic oil chamber.
[0019] Furthermore, the third adjustment assembly includes an adjustment block, which is fixedly connected to the air control piston rod and located outside the mating box. The adjustment block has a triangular wedge-shaped hole formed in it. The triangular wedge-shaped hole includes two inclined surfaces that gradually approach each other from top to bottom. A triangular fixing block is fixedly mounted on the distribution box and is positioned within the triangular wedge-shaped hole.
[0020] Furthermore, the regulating box is fixedly mounted with a plurality of connection blocks, which are sequentially distributed along the circumference of the regulating box. Each connection block defines a connecting slot, which is arranged along a first direction, which is horizontal and aligns with the length of the distribution box. Each connecting slot is provided with a first screw, which is capable of sliding along the first direction. The first screw connects the distribution box to the connection block.
[0021] Furthermore, the first connection box and the second connection box, the second connection box and the third connection box, and the third connection box and the fourth connection box are all fixedly connected by second screws.
[0022] The beneficial effects of the present invention are as follows: a distribution box installation structure of the present invention places the distribution box in the target position and wraps two clamps around the column through the provided adjustment mechanism, cleaning mechanism and two installation mechanisms. The use of a spiral clamp can adapt to columns of different diameters, and its applicability is stronger. Since the clamp is spiral-shaped, rainwater will flow along the spiral clamp, so that less rainwater will remain on the clamp, preventing the clamp from being rusted and damaged due to the failure to drain rainwater in time, thereby reducing its structural strength and installation stability. The adjustment mechanism drives the top rod to move toward the outside of the adjustment box, so that the clamp further clamps the column, thereby making the connection between the clamp and the column tighter and preventing loosening.
[0023] Initially, the friction belt is in its first state, positioned between the column and the clamp, with its friction side in contact with the column. The adjustment box is then rotated, driving the clamp first in a forward rotation and downward movement, then in a reverse rotation and upward movement. The clamp drives the friction belt, shifting it from the first state to the second state. During this movement, the friction belt cleans dust from the column, preventing dust particles and impurities from affecting the connection between the clamp and column, thus ensuring a more stable connection.

DETAILED DESCRIPTION
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0038] Reference Figures 1 to 11 As shown, an embodiment of the present invention provides a distribution box mounting structure for mounting a distribution box 110 on a vertically disposed column 120. The structure includes a regulating box, a regulating mechanism, a cleaning mechanism, and two mounting mechanisms. The regulating box is mounted on the distribution box 110, and vertical first channels 280 are respectively defined on the upper and lower sides of the regulating box.
[0039] Two mounting mechanisms are respectively arranged on the upper and lower sides of the adjustment box. Each mounting mechanism includes a push rod 223, a tightening block 222 and a clamp 220. The push rod 223 is arranged vertically, and each push rod 223 is arranged in a first channel 280 for sliding up and down. The tightening block 222 is fixedly arranged on the adjustment box. The clamp 220 is spiral-shaped, and 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 push rod 223. The adjustment mechanism drives the push rod 223 to slide up and down. The more the push rod 223 extends out of the adjustment box, the tighter the clamp 220 clamps the column 120.
[0040] The cleaning mechanism includes two friction belts 224, which are arranged along the spiral extension direction of the clamp 220. The friction belts 224 are fixedly connected to the lower side of each loop of the clamp 220. Along the radial direction of the column 120, the friction belts 224 have a friction side and a smooth side, respectively. The friction belts 224 have a first state and a second state. In the first state, the friction belts 224 are positioned between the column 120 and the clamp 220, with the friction side in contact with the column 120. In the second state, the friction belts 224 are positioned under each loop of the clamp 220, with the smooth side in contact with the column 120. The clamp 220 first rotates forward and moves downward, then rotates backward and moves upward. The clamp 220 drives the friction belt 224, causing the friction belt 224 to transition from the first state to the second state.
[0041] like Figure 6 As shown, the forward rotation of the clamp 220 is counterclockwise rotation, and the reverse rotation of the clamp 220 is clockwise rotation.
[0042] Place the distribution box 110 in the desired location and wrap the two clamps 220 around the column 120. The spiral-shaped clamps 220 can adapt to columns 120 of varying diameters, providing greater adaptability. Due to the spiral shape of the clamps 220, rainwater flows along the spiral, leaving less water on the clamps 220. This prevents rust damage to the clamps 220 due to delayed drainage, which could reduce their structural strength and installation stability.
[0043] In the initial state, the friction belt 224 is in the first state, the friction belt 224 is between the column 120 and the clamp 220, and the friction side of the friction belt 224 is in contact with the column 120. Then the adjustment box is rotated, and the adjustment box drives the clamp 220 to rotate forward and move downward, and then rotate reversely and move upward. The clamp 220 drives the friction belt 224 to move, so that the friction belt 224 is changed from the first state to the second state. During the movement, the friction belt 224 cleans the dust on the column 120 to prevent dust particles and impurities from affecting the connection between the clamp 220 and the column 120.
[0044] In this embodiment, the tightening block 222 is provided with a first horizontally disposed chute. Each mounting mechanism further includes a horizontally disposed screw rod 221, each screw rod 221 being rotatably disposed within the first chute. The clamp 220 is provided with a plurality of slots 225, which are sequentially distributed along the direction of the helical extension of the clamp 220. One end of the clamp 220 is slidably disposed within the first chute, with the screw rod 221 and the slots 225 engaging in a helical transmission. When the screw rod 221 rotates, the clamp 220 moves along the first chute.
[0045] After the two clamps 220 are wrapped around the column 120, due to the spiral fit between the spiral rod 221 and the clamping groove 225, the spiral rod 221 is rotated to move the clamps 220 toward the inside of the first sliding groove, preliminarily pre-tightening the clamps 220, and then connecting the clamps 220 and the column 120.
[0046] In this embodiment, the friction band 224 has a first side and a second side along the vertical direction, with the first side being the side where the friction band 224 is fixedly connected to the clamp 220. When the friction band 224 is in the first position, the second side of each loop of the friction band 224 is above the first side of the friction band 224, and the second side of each loop of the friction band 224 is flush with the upper side of each loop of the clamp 220. When the friction band 224 is in the second position, the second side of each loop of the friction band 224 is below the first side of the friction band 224, and the clamp 220 is in contact with the column 120.
[0047] In the initial state, the friction band 224 is in the first state, the friction band 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 circle of the friction band 224 is above the first side of the friction band 224, and the second side of the friction band 224 is flush with the upper side edge of each circle of the clamp 220.
[0048] The adjustment box is then rotated, driving the clamp 220 to rotate forward and move downward. Because the first side of the friction band 224 is fixedly connected to the clamp 220, the downward movement of the clamp 220 simultaneously drives the friction band 224 downward, cleaning the surface of the column 120. The clamp 220 is then rotated in the opposite direction, moving it upward. Because the friction side of the friction band 224 is in contact with the column 120, the friction bands 224 and the column 120 are in frictional contact. Therefore, when the clamp 220 moves upward, the clamp 220 drives the first side of the friction band 224 upward, while the second side of the friction band 224 remains stationary. The clamp 220 continues to move upward, driving the first side of the friction band 224 upward until the smooth side of the friction band 224 contacts the column 120, with the first side of the friction band 224 positioned above the second side and the friction band 224 positioned below each rotation of the clamp 220.
[0049] In this embodiment, the regulating 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 arranged in sequence from top to bottom. Two first channels 280 are respectively located in the first connection box 230 and the fourth connection box 260. The second connection box 240 and the third connection box 250 are both provided with a second channel 281, which is vertically arranged. The second channel 281 in the second connection box 240 is connected to the first channel 280 in the first connection box 230. The second channel 281 in the third connection box 250 is connected to the first channel 280 in the fourth connection box 260. Each first channel 280 is connected to a second channel 281 to form a first installation channel.
[0050] Each mounting mechanism further includes a piston cylinder 271 and a hydraulic piston rod 272. Both piston cylinder 271 and hydraulic piston rod 272 are vertically arranged. The piston cylinder 271 is detachably mounted within the first mounting channel and communicates with the second channel 281. One end of each hydraulic piston rod 272 is slidably mounted within a piston cylinder 271, and the other end of each hydraulic piston rod 272 is detachably connected to the push rod 223.
[0051] In this embodiment, a vertically disposed slot is defined within the first connection box 230. A hydraulic oil chamber 241 and a first oil delivery pipe 242 are defined within the second connection box 240. Hydraulic oil is contained within the hydraulic oil chamber 241, which communicates with the slot and the first oil delivery pipe 242, respectively. The first oil delivery pipe 242 communicates with the two second passages 281.
[0052] The adjustment mechanism includes a first adjustment assembly, which includes a screw 232. The screw 232 is vertically arranged and rotatably disposed in the empty slot and helically engaged with the empty slot. A first piston is fixedly disposed at the lower end of the screw 232 and is slidably disposed in the mounting hydraulic oil chamber 241.
[0053] Rotating the screw rod 232 causes it to move downward, which in turn drives the first piston to move downward synchronously, thereby squeezing the hydraulic oil in the installation hydraulic oil chamber 241. The hydraulic oil in the installation hydraulic oil chamber 241 flows through the first oil delivery pipe 242 into the two second channels 281, and then into the two piston cylinders 271, thereby pushing the hydraulic piston rod 272 away from the piston cylinder 271. The hydraulic piston rod 272 drives the push rod 223 to move toward the outside of the adjustment box, further tightening the clamp 220 and the column 120.
[0054] In this embodiment, a third channel 282 is defined in both the second connection box 240 and the third connection box 250. The two third channels 282 are interconnected. The second channel 281 on the second connection box 240 is interconnected with the third channel 282 on the second connection box 240, and the second channel 281 on the third connection box 250 is interconnected with the third channel 282 on the third connection box 250. A baffle 284 is fixedly disposed in each third channel 282, and each baffle 284 has a first through hole defined therein.
[0055] The adjustment mechanism also includes a second adjustment assembly, comprising two sliding blocks, each of which slides vertically within a first through-hole. A second piston 245 and a third piston 246 are fixedly mounted at each end of each sliding block, vertically. The second piston 245 is located on the side of the sliding block facing away from the adjacent sliding block, while the third piston 246 is located on the side of the sliding block facing closer to the adjacent sliding block. A baffle 284 and the third piston 246 form a variable-sized cavity 285 within the third channel 282. A thermally sensitive expansion material is disposed within the cavity 285.
[0056] During use, when the temperature rises, the thermosensitive expansion material in the cavity 285 expands. The thermosensitive expansion material in the two cavities 285 pushes the two third pistons 246 toward each other, so that the second piston 245 moves away from the second channel 281, generating negative pressure in the second channel 281. In turn, the hydraulic piston rod 272 drives the push rod 223 to move toward the inside of the adjustment box, thereby reducing the clamping force between the clamp 220 and the column 120, so as 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, thereby damaging the column 120 and the clamp 220.
[0057] When the temperature drops, the thermosensitive expansion material contracts and drives the two third pistons 246 away from each other, which in turn drives the push rod 223 toward the outside of the adjustment box through the hydraulic piston rod 272, 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 loosening due to cold shrinkage.
[0058] In this embodiment, the second connection box 240 is fixedly mounted with the matching box 210. A fourth channel is defined in the matching box 210, and the fourth channel is vertically arranged. A wind-controlled hydraulic oil chamber 248 and a second oil delivery pipe 247 are defined in the second connection box 240. Hydraulic oil is contained in the wind-controlled hydraulic oil chamber 248, which communicates with the fourth channel and the second oil delivery pipe 247. The second oil delivery pipe 247 is in communication with the two second channels 281.
[0059] The adjustment mechanism also includes a third adjustment component, which includes a wind control piston rod 213. The wind control piston rod 213 is vertically arranged, and the wind control piston rod 213 is slidably arranged in the fourth channel. The lower end of the wind control piston rod 213 is fixed with a fourth piston, and the fourth piston is arranged in the wind control hydraulic oil chamber 248.
[0060] In this embodiment, the third adjustment assembly also includes an adjustment block 214, which is fixedly connected to the air control piston rod 213 and located outside the mating box 210. Adjustment block 214 defines a triangular wedge-shaped hole 212, which includes two inclined surfaces that gradually approach each other from top to bottom. A triangular fixing block 111 is fixedly mounted on the distribution box 110 and positioned within the triangular wedge-shaped hole 212, with the two interlocking parts mating with each other.
[0061] In this embodiment, the regulating box is fixed with multiple connecting blocks 234, distributed sequentially along the circumference of the regulating box. Each connecting block 234 defines a connecting slot 233, which is arranged along a first direction, which is horizontal and aligns with the length of the distribution box 110. Each connecting slot 233 is provided with a first screw 235, which is slidable along the first direction. The first screws 235 connect the distribution box 110 to the connecting block 234.
[0062] In the presence of wind, torque will be generated between the distribution box 110 and the regulating box, causing displacement between the distribution box 110 and the regulating box. Since the triangular fixing block 111 is set in the triangular wedge-shaped hole 212, when displacement occurs between the distribution box 110 and the regulating box, the triangular fixing block 111 squeezes the regulating block 214, causing the regulating block 214 to move downward. The regulating 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 chamber 248, and presses the hydraulic oil in the wind control hydraulic oil chamber 248 into the two second channels 281 through the second oil pipe 247. The hydraulic piston rod 272 drives the push rod 223 to move toward the outside of the regulating box, so that the clamp 220 and the column 120 are further clamped.
[0063] 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.
[0064] Working process: Connect the distribution box 110 and the connecting block 234 using the first screw 235. Then, place the distribution box 110 in the desired location and wrap the two clamps 220 around the column 120. Because the spiral rod 221 and the clamping slot 225 engage, rotating the spiral rod 221 moves the clamps 220 toward the interior of the first chute, pre-tightening them and connecting them to the column 120. The spiral-shaped clamps 220 can accommodate columns 120 of varying diameters, providing greater adaptability.
[0065] In the initial state, the friction band 224 is in the first state, the friction band 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 circle of the friction band 224 is below the first side of the friction band 224, and the second side of the friction band 224 is flush with the upper side edge of each circle of the clamp 220.
[0066] Then, the regulating box is rotated, and the regulating box drives the clamp 220 to rotate in the forward direction first. Figure 7 As shown, when the clamp 220 rotates forward, that is, the clamp 220 rotates counterclockwise and moves downward along the tangential direction of the clamp 220. When the clamp 220 rotates reversely, that is, the clamp 220 rotates clockwise and moves upward along the tangential direction of the clamp 220.
[0067] like Figure 11 As shown, since the first side of the friction band 224 is fixedly connected to the clamp 220, when the clamp 220 moves downward, it simultaneously moves the friction band 224 downward, cleaning the surface of the column 120. The clamp 220 is then rotated in the opposite direction, moving it upward. Because the friction side of the friction band 224 is in contact with the column 120, the friction band 224 and the column 120 are in frictional contact. Therefore, when the clamp 220 moves upward, the clamp 220 moves the first side of the friction band 224 upward, while the second side of the friction band 224 does not move. The clamp 220 continues to move upward, continuously moving the first side of the friction band 224 upward, until the smooth side of the friction band 224 contacts the column 120. The first side of the friction band 224 is above the second side of the friction band 224, and the friction band 224 is located below each rotation of the clamp 220. The friction belt 224 cleans the dust on the column 120 during the movement, so as to prevent dust particles and impurities from affecting the connection between the clamp 220 and the column 120 .
[0068] Finally, the screw rod 232 is rotated to move the screw rod 232 downward. The screw rod 232 drives the first piston to move downward synchronously, thereby squeezing the hydraulic oil in the installation hydraulic oil chamber 241. The hydraulic oil in the installation hydraulic oil chamber 241 enters the two second channels 281 through the first oil pipe 242, and then enters the two piston cylinders 271, thereby pushing the hydraulic piston rod 272 to move away from the piston cylinder 271. The hydraulic piston rod 272 drives the push rod 223 to move outside the regulating box. The push rod 223 drives the clamp 220 to move, so that the length of the clamp 220 along the axial direction of the 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 column 120 are further clamped. At this point, the installation of a distribution box installation structure is completed.
[0069] Since the clamp 220 is spiral, rainwater will flow along the spiral clamp 220, so that less rainwater will remain on the clamp 220, preventing the clamp 220 from being corroded and damaged due to the failure to discharge rainwater in time, thereby reducing its structural strength and installation stability.
[0070] During use, when the temperature rises, the thermosensitive expansion material in the cavity 285 expands. The thermosensitive expansion material in the two cavities 285 pushes the two third pistons 246 toward each other, so that the second piston 245 moves away from the second channel 281, generating negative pressure in the second channel 281. In turn, the hydraulic piston rod 272 drives the push rod 223 to move toward the inside of the adjustment box, thereby reducing the clamping force between the clamp 220 and the column 120, so as 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, thereby damaging the column 120 and the clamp 220.
[0071] When the temperature drops, the thermosensitive expansion material contracts and drives the two third pistons 246 away from each other, which in turn drives the push rod 223 toward the outside of the adjustment box through the hydraulic piston rod 272, 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 loosening due to cold shrinkage.
[0072] In windy conditions, torque is generated between the distribution box 110 and the regulating box, causing displacement between them. Since the triangular fixing block 111 is positioned within the triangular wedge-shaped hole 212, when displacement occurs between the distribution box 110 and the regulating box, the triangular fixing block 111 squeezes the regulating block 214, causing it to move downward. The regulating 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 chamber 248, and presses the hydraulic oil in the wind control hydraulic oil chamber 248 into the two second channels 281 through the second oil pipe 247. The hydraulic piston rod 272 drives the push rod 223 to move toward the outside of the regulating box, so that the clamp 220 and the column 120 are further clamped, which can ensure that the greater the torque brought by the wind to the distribution box 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.
[0073] When the installation of a distribution box installation structure is completed, the clamping force between the clamp 220 and the column 120 is the target clamping force.
[0074] Depending on the material of the column 120, the piston cylinder 271 and hydraulic piston rod 272 can be replaced with different inner diameters. For example, when the column 120 is made of a softer material such as wood or a harder material such as metal, the thermal expansion coefficient of a metal column 120 is greater than that of a wood column 120. The clamping force increases more when the metal column 120 expands upon heating, while the clamping force increases less when the wood column 120 expands upon heating.
[0075] Under the same temperature environment, because the thermal expansion material remains unchanged, the thrust exerted by the second adjustment assembly on the hydraulic piston rod 272 remains constant. Therefore, when the column 120 is made of wood, the inner diameter of the piston cylinder 271 is increased. Consequently, when the thrust exerted by the second adjustment assembly on the hydraulic piston rod 272 remains constant, the hydraulic piston rod 272 and the push rod 223 move less, resulting in a smaller reduction in the clamping force between the clamp 220 and the wood column 120. This minimizes the increase in clamping force caused by the heated expansion of the wood column 120, maintaining the target clamping force between the clamp 220 and the column 120.
[0076] When the column 120 is made of metal, the inner diameter of the piston cylinder 271 is smaller, the push rod 223 moves more, and the clamping force between the clamp 220 and the column 120 made of wood is reduced more to adapt to the larger clamping force that increases after the column 120 made of metal expands after being heated, so that the clamping force between the clamp 220 and the column 120 maintains the target clamping force.
[0077] The clamping force between the clamp 220 and the column 120 is prevented from being too large to damage the clamp 220 and the column 120 , and from being too small to cause looseness.
[0078] 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 matches the triangular wedge-shaped hole 212, when the column 120 is made of wood, 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. The more the adjustment block 214 drives the air control piston rod 213 downward, the more the air control piston rod 213 pushes the hydraulic oil in the air control hydraulic oil chamber 248 into the second channel 281 through the second oil pipe 247, thereby maintaining the same extension of the hydraulic piston rod 272, and thus maintaining the same clamping force between the clamp 220 and the column 120.
[0079] When the column 120 is made of metal, the inner diameter of the piston cylinder 271 is smaller. The larger the angle between the two inclined surfaces, the less the adjustment block 214 drives the air control piston rod 213 to move downward, and the air control piston rod 213 pushes less hydraulic oil in the air control hydraulic oil chamber 248 into the second channel 281 through the second oil pipe 247, thereby making the hydraulic piston rod 272 maintain the same extension, so that the clamping force between the clamp 220 and the column 120 remains consistent.
