Description

Technical Field

[0001] The invention relates to the technical field of cable bridges, and in particular to a wiring-adjustable cable bridge. Background Art

[0002] A cable tray is a laying device used to install cables. During cable installation, the inner side of the cable tray is compressed and the outer side is tensile at the bends, and the equivalent heat dissipation surface area may be reduced by 10% to 15%. In addition, the bends are mostly plate splicing, welding / bolting, which increases the contact thermal resistance and reduces the thermal conductivity. When the cable is bent, the conductor deforms, and the local cross-sectional area is reduced (especially for multi-core cables). The AC resistance increases due to the intensified skin effect. Secondly, the bends (such as 90° right-angle elbows) are prone to wind speed attenuation, forming a flow dead zone. The air convection velocity is 30%-50% lower than that of the straight section, and the heat dissipation capacity is significantly reduced.

[0003] The utility model with application number CN201920342100.0 specifically discloses a curved cable tray with easy heat dissipation, comprising a bottom trough (1) and a cover plate (2), wherein the cover plate (2) is fixed to the upper surface of the bottom trough (1); the bottom trough 1 comprises a front side plate (3), a rear side plate (4) and at least two bottom side plates (5), wherein the bottom side plates (5) fix the front side plate (3) and the rear side plate (4) into one body, and the bottom side plates (5) are fixed in parallel at intervals to form a heat dissipation channel. The cable tray of the utility model has better heat dissipation performance and is more convenient to install and disassemble.

[0036] like Figures 1 to 7 As shown, the present invention relates to a wiring adjustable cable tray, including: a straight-through cable tray and a right-angle cable tray; the right-angle cable tray includes: a first mounting plate 1, which is n-shaped to form a snap-fit ​​structure; a second mounting plate 2 connected to the end of the first mounting plate 1, and the second mounting plate 2 forms a first right angle when connected to the first mounting plate 1; a first cover plate 3 is snapped into the first mounting plate 1, and the first cover plate 3 is U-shaped as a whole, matching the snap-fit ​​structure formed with the first mounting plate 1, so that the first cover plate 3 can be tightly connected to the first mounting plate 1; the U-shaped end of the first cover plate 3 is bent inward to form a reinforcement structure.

[0037] The second mounting plate 2 is internally clamped with the second cover plate 4 , wherein the first mounting plate 1 and the second mounting plate 2 have the same structure, and the first cover plate 3 and the second cover plate 4 have the same structure, which will not be described in detail here.

[0038] One end where the first mounting plate 1 and the second mounting plate 2 are connected to each other is also connected to a third cover plate 5. The third cover plate 5 is in the shape of a right-angled trapezoid, and its right-angled part matches the first right angle; the end of the third cover plate 5 is connected to a first vertical plate 6, and the bottom of the first vertical plate 6 is connected to a fourth cover plate. The fourth cover plate has the same structure as the third cover plate 5.

[0039] During installation, first install the first mounting plate 1 and the second mounting plate 2, and then install the first cover plate 3, the third cover plate 5, the first vertical plate 6, the fourth cover plate, and the second cover plate 4 in sequence to complete the installation of the right-angle bridge. After the right-angle bridge is installed, a through-type installation cavity for installing cables is formed inside it.

[0040] A cable limiter 7 is installed at the bottom of the installation cavity, and the cable limiter 7 includes: a cooling chamber 71 installed at the bottom inner side of the installation cavity, a limit block 72 slidably installed on the top of the cooling chamber 71, and an adjusting column detachably installed vertically between the cooling chamber 71 and the limit block 72; the interior of the cooling chamber 71 is hollow to form a liquid flow channel, wherein the bottom end of the limit block 72 is located inside the cooling chamber 71; an arc-shaped groove is provided on the top of the limit block 72 for limiting the cable, and a connecting through hole is provided laterally on the upper edge of the arc-shaped groove for fixing the cable with a U-shaped clamp; the adjusting column is composed of two round rods threaded together, and the height of the adjusting column can be adjusted by rotating the round rods.

[0041] During installation, by adjusting the distance between two adjacent cooling chambers 71, the distance between two adjacent limit blocks 72 can be adjusted, thereby adjusting the lateral distance between the cables; by adjusting the height of the adjusting column, the size of the cooling chamber 71 or the height of the cable can be adjusted; for example, when the cables to be installed are thicker or denser, the distance between the two adjacent cables can be adjusted so that they are horizontally away from each other, thereby increasing the heat dissipation gap; the height of the adjusting column can also be adjusted so that the two adjacent cables can be staggered in the longitudinal space, thereby further increasing the heat dissipation gap, which is beneficial to heat dissipation at the bends of the right-angle bridge; in addition, when the power cables and control signal cables are staggered, the increase in vertical spacing can reduce the electromagnetic coupling effect, and an electromagnetic shielding area can be constructed in conjunction with a metal partition. For example, the three-phase cables are arranged in a spatially staggered triangle, which can optimize the magnetic field balance and reduce eddy current losses.

[0042] A number of heat dissipation openings are provided on the side wall of the first mounting plate 1; a heat dissipation hole 51 is provided on the third cover plate 5, and a shielding member 52 is provided above the heat dissipation hole 51 to block the heat dissipation hole 51, the bottom of the shielding member 52 matches the heat dissipation hole 51, and the top of the shielding member 52 is larger than the bottom; a reset member 53 is provided between the shielding member 52 and the third cover plate 5, and the reset member 53 is used to make the third cover plate 5 and the shielding member 52 move away from each other; in the natural state, the reset member 53 props up the shielding member 52 to separate the shielding member 52 from the heat dissipation hole 51, so that heat can be dissipated, and the reset member 53 can be optionally a spring; a collection and cleaning assembly 8 is installed on the side wall of the first vertical plate 6.

[0043] The collecting and cleaning assembly 8 includes: a support rod 84 installed on the top of the third cover plate 5, an adsorption expansion body 81 installed on the support rod 84, the adsorption expansion body 81 is located above the shielding member 52, and there are four support rods 84, which are arranged around the adsorption expansion body 81; a mounting block is provided on the side of the third cover plate 5 close to the first vertical plate 6, and a water collecting plate 82 is rotatably installed on the mounting block, and the side of the water collecting plate 82 close to the adsorption expansion body 81 is located above the adsorption expansion body 81; the top of the water collecting plate 82 gradually concave downward from the outside to the inside, forming a water guide groove, which is used to guide rainwater to the lower end of the water collecting plate 82; the top of the two support rods 84 close to one side of the water collecting plate 82 is provided with a connecting structure 841, which is connected to the bottom of the water collecting plate 82. The connecting structure 841 can be selected from a magnet or a common snap-on structure, which is used to limit the water collecting plate 82 in a natural state.

[0044] The outer layer of the adsorption expansion body 81 is set as a hydrophobic breathable membrane 812 (such as polytetrafluoroethylene), and the inner layer is set as an expansion part 813. An elastic support part 814 is set inside the expansion part 813. The elastic support part 814 is used to absorb part of the stress through its own elastic deformation when the expansion part 813 expands, so as to prevent excessive deformation or rupture of the structure; the expansion part 813 is made of a water-absorbing resin 8131 and a heat-sensitive material 8132 arranged in sequence from top to bottom; the water-absorbing resin 8131 is preferably a highly absorbent resin (such as a sheet-like SAP composite fiber material made of cross-linked polyacrylic acid sodium salt, which has more uniform expansion deformation. When the air humidity is ≤50%, the expansion rate of the above material is ≤2 times; when the air humidity is 50%-80%, the expansion rate is 3-5 times; when the air humidity is ≥80%, SAP absorbs water and expands 5-10 times, pushing the shield The block closes the heat dissipation hole); the thermosensitive material 8132 can be optionally a shape memory polymer (such as a sheet material made of Glycerol-based SMP foam, the trigger temperature can be set to 40-50°C based on demand, and the volume changes by 0.5-1% for every 1°C increase); the elastic support part 814 can be optionally a silicone corrugated sheet; the breathable membrane only allows gaseous water molecules to pass through, ensuring that the water absorption rate of the adsorption expansion body 81 matches the actual humidity in the environment, avoiding false triggering caused by direct immersion in liquid water, and avoiding impurities (such as mud and sand) that may be carried in the liquid water from clogging the micropores of the adsorption expansion body 81, reducing its air permeability and response speed; the water-absorbing resin 8131 can expand in volume after absorbing water and shrink inversely after drying; a drainage channel is provided on the hydrophobic breathable membrane 812 at the bottom to accelerate the drying and shrinkage speed of the water-absorbing resin 8131.

[0045] In rainy areas in the south, humidity fluctuates frequently. When it is rainy and the humidity in the air is high (for example, the air humidity is ≥80% or when it comes into contact with rain), the adsorption expansion body 81 absorbs water and expands, and its upper and lower sides respectively squeeze the water collecting plate 82 and the shielding member 52, thereby driving the water collecting plate 82 to deflect, separating the support rod 84 from the water collecting plate 82, and causing the shielding member 52 to close the heat dissipation hole 51; when the weather turns clear, the water in the adsorption expansion body 81 gradually evaporates and the volume shrinks. Under the action of the first spring 811, the adsorption expansion body 81 separates from the shielding member 52, and the shielding member 52 moves upward under the action of the reset member 53 and no longer blocks the heat dissipation hole 51; at the same time, the water collecting plate 82 continues to swing under the action of the wind until it returns to its original position when the connecting structure 841 is connected.

[0046] In addition, under high temperature conditions in summer, the external humidity may not be high. If the heat dissipation holes 51 are still sealed at this time, the temperature inside the cable tray may be too high. Therefore, under high temperature conditions, the thermosensitive material 8132 expands, replacing the water-absorbing resin 8131 to expand; specifically, the surface temperature of the cable tray in summer is about 38°C–50°C (5°C–15°C higher than the ambient temperature), high humidity environment (air humidity ≥80% or rain): the adsorption expansion body 81 absorbs water and expands, closing the heat dissipation holes 51; high temperature and low humidity environment (temperature ≥50°C and air humidity <60%): the thermosensitive material 8132 expands due to heat, closing the heat dissipation holes 51; high temperature and high humidity environment (temperature ≥50°C and humidity ≥80%): the two materials work together to enhance the reliability of the closing of the heat dissipation holes 51.

[0047] A collecting box 83 is provided on the outlet side of the water collecting plate 82 (the side close to the first vertical plate 6), and the collecting box 83 is installed on the first vertical plate 6; the collecting box 83 is in the shape of a rectangular parallelepiped as a whole, and has an opening at the top for water inlet, and a discharge chute is provided on the side away from the first vertical plate 6 to facilitate the discharge of impurities; a first return spring 821 is installed on the side of the water collecting plate 82 close to the collecting box 83, and the first return spring 821 is connected to the third cover plate 5; a protective plate 836 is installed on the top of the collecting box 83, and the protective plate 836 is used to reduce debris falling into the collecting box 83; a coarse filter screen 831 is provided below the protective plate 836, and the coarse filter screen 831 is used to preliminarily filter rainwater and filter out large particles of impurities.

[0048] The coarse filter 831 is rotatably connected to the collection box 83 at one end away from the water collecting plate 82, and the top of the other end (i.e., the movable end) is hinged with a first hinge rod 8311, and the first hinge rod 8311 is hinged with a second hinge rod 8312, and the other end of the second hinge rod 8312 is hinged with the bottom of the water collecting plate 82, so that the end of the coarse filter 831 close to the water collecting plate 82 can swing downward; when the water collecting plate 82 is connected to the connecting structure 841, the first hinge rod 8311 and the second hinge rod 8312 are straightened, and the coarse filter 831 is in a state of being rotatably connected to the collection box 83. The net 831 cannot swing; when the water collecting plate 82 is separated from the connecting structure 841, there is a movement gap between the first hinged rod 8311 and the second hinged rod 8312, so that when the water from the water collecting plate 82 flows onto the coarse filter screen 831, the water flow will cause the coarse filter screen 831 to further swing slightly. The dynamic swing of the coarse filter screen 831 can avoid the accumulation of impurities in local areas and improve the uniformity of filtration. At the same time, the direction of water flow is coordinated with the swing direction of the coarse filter screen 831 to enhance the impurity stripping effect and facilitate impurities to fall from the surface of the coarse filter screen 831.

[0049] A diverter plate 832 is also slidably installed inside the collection box 83. The diverter plate 832 is located below the coarse filter 831, and a second return spring 838 is connected to the bottom of the diverter plate 832. The diverter plate 832 and the coarse filter 831 are softly connected by a connecting piece 837, so that when the diverter plate 832 diverts flow, it can drive the coarse filter 831 to swing.

[0050] The collecting box 83 is provided with a liquid outlet channel 835 near the bottom. The liquid outlet channel 835 is located below the diverter plate 832. A fine filter screen 833 is provided at the water inlet end of the liquid outlet channel 835. The fine filter screen 833 is used to filter the rainwater again. The outlet end of the liquid outlet channel 835 is connected to the cooling chamber 71. The rainwater filtered again by the coarse filter screen 831 and the washing filter screen flows into the cooling chamber 71 from the water outlet end. Cleaning parts 834 are respectively installed on the upper and lower sides of the diverter plate 832. The cleaning side of the cleaning part 834 faces the fine filter screen 833, so that the cleaning part 834 can clean the fine filter screen 833. When cleaning downward, the cleaned impurities enter the bottom of the diverter plate 832. There is a cavity below the diverter plate 832, which is used as a sewage outlet. The liquid outlet channel 835 can be set as one, located in the middle position near the bottom of the collecting box 83, or it can be set as two, symmetrically installed on the left and right sides of the collecting box 83.

[0051] When the air humidity reaches the threshold, the adsorption expansion body 81 absorbs water and expands, causing the shielding member 52 to cover the heat dissipation hole 51. At the same time, the adsorption expansion body 81 deflects the water collecting plate 82, causing the support rod 84 to separate from the water collecting plate 82. Then, the rainwater on the water collecting plate 82 flows to the collection box 83; the water flows through the coarse filter 831 to remove large particles of impurities; then the water flows to the diverter plate 832 for accumulation, causing the diverter plate 832 to slide downward, and the water flows through the space between the diverter plate 832 and the collection box 83. At this time, the fine filter 833 filters the water again to remove tiny particles and impurities. At the same time, since the cleaning member 834 is installed on the diverter plate 832, as the diverter plate 832 slides downward intermittently, the cleaning member 834 cleans the fine filter 833 to prevent the fine filter 833 from being blocked, ensuring that the liquid outlet channel 835 can continuously and stably transport the clean water filtered by the fine filter 833 to the cooling chamber 71, so that Evaporation and heat dissipation are carried out inside the cable tray to cool the cable; at the same time, the diverter plate 832 drives the coarse filter 831 to swing downward, and the coarse filter 831 drives the water collecting plate 82 to swing further downward; when the diverter plate 832 slides upward, it will temporarily block the water from flowing to the water inlet end of the liquid outlet channel 835, so that the water in the collection box 83 accumulates in a short time. This intermittent drainage method can more reasonably control the amount of water entering the cooling chamber 71 and avoid excessive or insufficient water in a short period of time; at the same time, when the diverter plate 832 slides upward, the water collecting plate 82 and the coarse filter 831 are reset upward; the up and down sliding of the diverter plate 832 can not only drain water intermittently, but also clean the fine filter 833, and can also drive the water collecting plate 82 to swing, so that rainwater is sprinkled back and forth on the coarse filter 831, avoiding rainwater from scouring the same position of the coarse filter 831 for a long time, and can also drive the coarse filter 831 to swing, so that impurities fall from the surface of the coarse filter 831.
