During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection.
[0003] The existing distribution boxes for electrical automation equipment mostly have mounting plates fixed inside the cabinet during installation, and the spacing between multiple mounting plates cannot be adjusted as needed. Moreover, when the equipment is installed in the distribution box, if the spacing between the equipment needs to be adjusted, the equipment mostly needs to be disassembled and reinstalled. The distance adjustment process is troublesome, time-consuming and labor-intensive. In addition, the heat dissipation structure in the closed distribution box usually uses an exhaust fan to discharge the hot air in the distribution box through the air outlet, and draws external air into the distribution box for heat dissipation.

[0017] 1. The present application provides a distribution box for electrical automation equipment with a heat dissipation function.

Since the number of teeth of the second gear is different from that of the first gear, when the first motor drives the second gear to rotate, the second gear drives the first gear to rotate at an increased speed, and the rotating first gear drives the connected vortex fan to rotate at a high speed. The suction force generated by the high-speed rotating vortex fan will drive the hot air flow emitted by the equipment in the inner cabinet to be drawn into the exhaust pipe, and enter the heat conduction pipe through the exhaust pipe, and the air flow along When the heat pipe flows to the area where the refrigerant liquid storage pipe is located, the cold air emitted by the refrigerant in the refrigerant liquid storage pipe initially cools the hot air flow.

DETAILED DESCRIPTION
[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0036] like Figure 1-10As shown, the present application provides a distribution box with heat dissipation function for electrical automation equipment, including an outer cabinet 1, an inner cabinet 5 is provided in the outer cabinet 1, an adjustable distance mechanism 8 is provided in the inner cabinet 5, a heat dissipation mechanism 7 is installed on the inner cabinet 5, and the adjustable distance mechanism 8 includes a group of camshafts 83 symmetrically distributed in the inner cabinet 5, the camshaft 83 is rotatably connected to the inner cabinet 5, one end of the camshaft 83 is connected through one end of the inner cabinet 5, a smooth groove 85 is provided in the middle of the camshaft 83, and a plurality of variable distance grooves 84 are symmetrically distributed at both ends of the smooth groove 85, and the plurality of variable distance grooves 84 are provided on the surface of the camshaft 83, and the shape of the variable distance groove 84 is a spiral arc, and the spiral arc length between the plurality of variable distance grooves 84 is gradually increased in multiples, and a plurality of adjustable distance grooves 84 are distributed between a group of camshafts 83. The limiting plate 88 has a spacing, and a group of connecting suspension rods 814 are fixedly connected to the limiting plate 88, and the connecting suspension rods 814 can be connected to the smooth groove 85 and the pitch-changing groove 84. The limiting plate 88 is detachably connected to the mounting plate 81, and a group of camshafts 83 pass through one end of the inner cabinet 5 and are distributed and fixed with a turbine 812. One end of a group of turbines 812 is provided with a shaft 810, and the shaft 810 is symmetrically fixedly connected to a group of worm assemblies 811 meshing with the corresponding turbines 812. A second motor 87 is fixed to one end of the shaft 810, and a plurality of guide holes 813 are equidistantly provided on the limiting plate 88, and a guide rod 82 is connected through the guide hole 813. The number of guide rods 82 matches the number of guide holes 813, and both ends of the guide rod 82 are fixedly connected to the inner cabinet 5.
[0037] In this embodiment, when adjusting the spacing between the devices, the second motor 87 drives the shaft 810 fixedly connected to the output end to rotate, and the rotating shaft 810 drives a group of worm assemblies 811 fixed thereon to rotate, and the rotating worm assembly 811 drives a group of meshing turbines 812 to rotate, and the rotating group of turbines 812 drives a corresponding group of camshafts 83 to generate dynamic rotation, and the group of camshafts 83 that generates dynamic rotation will drive the corresponding smooth grooves 85 and pitch-changing grooves 84 thereon to generate dynamic changes during the rotation process. Since the smooth groove 85 is perpendicular to the corresponding limit plate 88, the dynamic rotation change of the smooth groove 85 is caused by the connecting rod 814 fixed to the limit plate 88 connected thereto, which remains in the same position. When the pitch is changed The slot 84 will change dynamically when the camshaft 83 rotates. The dynamically changing pitch slot 84 will push the connecting boom 814 connected thereto to change the height of the spiral trajectory of the pitch slot 84, thereby driving the limit plate 88 fixedly connected to the connecting boom 814 to change the height, so that the spacing between the multiple limit plates 88 distributed between a group of camshafts 83 will change, driving the mounting plate 81 fixed at one end of the limit plate 88 and the electrical automation equipment installed on the mounting plate 81 to change the spacing synchronously. When the limit plate 88 changes in height, the guide hole 813 opened on it will slide along the guide rod 82, thereby improving the stability of the limit plate 88 sliding up and down, which is beneficial to prevent the sliding trajectory of the limit plate 88 from deviating during the sliding adjustment process of the limit plate 88.
[0038] It should be noted that the worm assembly 811 can drive the turbine 812 to produce slow forward and reverse rotation. The lead angle of the turbine 812 and the worm assembly 811 structure is a medium lead angle of 10°-15°. The spiral direction of the worm assembly 811 is opposite to that of the turbine 812 to ensure uniform contact of the tooth surface during forward and reverse rotation and reduce the reversing shock. The number of a group of camshafts 83, a group of connecting rods 814, a group of turbines 812 and a group of worm assemblies 811 meshing with the corresponding turbines 812 is two.
[0039] like Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, a group of latch rods 86 are symmetrically fixedly connected to the limit plate 88, and a group of contraction cavities 815 are symmetrically opened on the group of latch rods 86. An auxiliary spring 816 is provided in the contraction cavity 815, and a positioning block 89 is fixed at one end of the auxiliary spring 816. The positioning block 89 is telescopically connected to the contraction cavity 815, and four limit sliders are symmetrically fixedly connected to the positioning block 89. Four limit sliding grooves matching the limit sliding blocks are symmetrically opened in the contraction cavity 815.
[0040] In this embodiment, when installing equipment into the distribution cabinet, the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be installed are installed on the corresponding mounting plate 81 and the equipment is connected to the U-shaped card clamp opened on the mounting plate 81. When the equipment is fixed to the mounting plate 81, the symmetrical holes opened on the mounting plate 81 are clamped onto a group of latch rods 86 symmetrically fixedly connected to the limit plate 88, and the mounting plate 81 is pushed. The mounting plate 81 will slide along the latch rods 86 toward the limit plate 88 under the restriction of the hole cavity. At this time, the inner wall of the hole cavity will push and contact it. The positioning block 89 shrinks and slides into the shrinkage cavity 815 under the action of the auxiliary spring 816. When the hole cavity opened on the mounting plate 81 is separated from the positioning block 89, the elastic potential energy generated by the auxiliary spring 816 after the positioning block 89 loses the extrusion force will push the positioning block 89 to extend out of the shrinkage cavity 815 to a specified distance and reset under the restriction of the four limit sliders and the four limit slots, thereby blocking the sliding trajectory of the mounting plate 81 to one end, which is helpful to prevent the installed mounting plate 81 from sliding to one end along the latch rod 86 and separating from the latch rod 86 under the pull of external force.
[0041] It should be noted that the number of one group of latch rods 86 and one group of contraction cavities 815 is two. One end of the positioning block 89 has an inclined angle, which makes it convenient for the mounting plate 81 to be quickly inserted into the hole cavity opened on the mounting plate 81 when sliding.
[0042] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a mounting slot 6 is provided at one end of the inner cabinet 5, and the heat dissipation mechanism 7 includes an exhaust pipe 71 fixed to the middle part of one end of the mounting slot 6, a fixed cover plate 714 is fixed with a clamp on the exhaust pipe 71, and a vortex fan 715 is rotatably connected to the middle part of one end of the fixed cover plate 714, and the vortex fan 715 is located in the exhaust pipe 71, and a heat conduction pipe 72 is fixed to the middle part of the exhaust pipe 71, and the other end of the heat conduction pipe 72 is fixedly connected to a cooling box 74, and a plurality of heat pipe heat dissipation modules 710 are equidistantly distributed in the cooling box 74, and a plurality of guide plates 711 are fixedly connected to one end of the cooling box 74, and an air supply pipe 716 is fixedly connected to the other end of the cooling box 74, and a refrigerant storage pipe 73 is fixed at the connection position between the heat conduction pipe 72 and the cooling box 74, and a sealing cover plate is fixed to the other end of the mounting slot 6 by bolts. 9. One end of the air supply pipe 716 is connected with the end opposite to the exhaust pipe 71 on the inner cabinet 5. The position where one end of the air supply pipe 716 passes through the inner cabinet 5 is clamped with a filter disc 717. The middle of the filter disc 717 is fixed with a dust cover 79. The cooling box 74 is located in the spacing space between the inner cabinet 5 and the outer cabinet 1. One end of the cooling box 74 is clamped with a sealing blocking plate 75. The other end of the fixed cover 714 is rotatably connected to the first gear 76. One end of the vortex fan 715 is connected with the middle of the fixed cover 714. One end of the vortex fan 715 is fixedly connected to the middle of one end of the first gear 76. One end of the first gear 76 is meshed with the second gear 77. The middle of one end of the second gear 77 is fixed with a first motor 78. The first motor 78 is installed and fixed in the mounting groove 6.
[0043] In this embodiment, when dissipating heat, the first motor 78 drives the second gear 77 fixedly connected to the output end to rotate, and the rotating second gear 77 drives the first gear 76 meshed with one end to rotate. Since the number of teeth of the second gear 77 and the first gear 76 is different, when the first motor 78 drives the second gear 77 to rotate, the second gear 77 drives the first gear 76 to rotate at an increased speed, and the rotating first gear 76 drives the connected vortex fan 715 to rotate at a high speed. The suction force generated by the high-speed rotating vortex fan 715 drives the hot air flow emitted by the equipment in the inner cabinet 5 to be drawn into the exhaust pipe 71, and enters the heat conduction pipe 72 through the exhaust pipe 71. The air flow along When the heat transfer pipe 72 flows to the area where the refrigerant storage pipe 73 is located, the cold air emitted by the refrigerant in the refrigerant storage pipe 73 initially cools the hot air flow. When the air flow after the initial cooling enters the cooling box 74, the air flow is cooled for a second time by the multiple heat pipe heat dissipation modules 710 provided in the cooling box 74. When the completely cooled air flow contacts the multiple guide plates 711, it will flow toward one end along the multiple guide plates 711. When the air flow flows into the air supply pipe 716, it will flow along the air supply pipe 716 in the direction of the filter plate 717, pass through the filter plate 717, and flow along the outer shape of the dust cover 79 into the inner cabinet 5, thereby cooling the equipment that dissipates heat in the inner cabinet 5.
[0044] It should be noted that the provision of the dust cover 79 is beneficial to preventing external dust and debris from falling onto the filter plate 717 and clogging the filter plate 717. The provision of multiple guide plates 711 is used to increase the residence time of the hot air flow in the cooling box 74 and improve the cooling efficiency of the hot air flow. A temperature sensor can be installed under the exhaust pipe 71 to connect to the controller of the first motor 78. When the temperature sensor senses that the temperature inside the inner cabinet 5 is too high, it transmits data to the controller, and the controller starts the first motor 78.
[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, one end of the outer cabinet body 1 is clamped with a sealing plate 2, one end of the sealing plate 2 is fixed to the shielding strip 3, and a cabinet door 4 is opened and closed inside the shielding strip 3. The middle clamp of the inner cabinet body 5 is clamped with a limiting clamp 10, and the limiting clamp 10 is fixed to the inner cabinet body 5. One end of the heat pipe cooling module 710 is fixedly connected with a docking tenon 712, and a docking tenon groove 713 is provided at the connection position between the docking tenon 712 and the cooling box 74.
[0046] In this embodiment, when installing the heat pipe cooling module 710, the docking tenon 712 fixed on the heat pipe cooling module 710 is clamped into the docking tenon groove 713 opened in the cooling box 74, so that the heat pipe cooling module 710 can be installed by clamping into the cooling box 74, and then the sealing plate 2 is clamped onto the outer cabinet 1, so that the sealing blocking plate 75 fixed on the sealing plate 2 is clamped to one end of the cooling box 74, and one end of the cooling box 74 is sealed. The shielding strip 3 blocks the gap between the cabinet door 4 and the sealing plate 2, which is beneficial to prevent external water stains or dust from entering the inner cabinet 5 through the gap, and the cabinet door 4 blocks the inner cabinet 5.
[0047] Working principle:
[0048] When installing equipment into the distribution cabinet, the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be installed are installed on the corresponding mounting plate 81 and the equipment is connected to the U-shaped card clamp opened on the mounting plate 81. When the equipment is fixed to the mounting plate 81, the symmetrical holes opened on the mounting plate 81 are clamped onto a group of latch rods 86 symmetrically fixedly connected to the limit plate 88, and the mounting plate 81 is pushed. The mounting plate 81 will slide along the latch rods 86 toward the limit plate 88 under the restriction of the hole. At this time, the inner wall of the hole will push the positioning block 89 in contact with it to shrink and slide into the shrinkage cavity 815 under the action of the auxiliary spring 816. When the hole opened on the mounting plate 81 is separated from the positioning block 89, the positioning block 89 loses its extrusion force and the auxiliary spring 816 The elastic potential energy generated will push the positioning block 89 to extend a specified distance out of the contraction cavity 815 under the restriction of the four limit sliders and the four limit slots to reset, so that the mounting plate 81 is installed and fixed on the limit plate 88 and the second motor 87 drives the shaft 810 fixedly connected to the output end to rotate. The rotating shaft 810 will drive a group of worm assemblies 811 fixed thereon to rotate. The rotating worm assembly 811 will drive a group of meshing turbines 812 to rotate. The rotating group of turbines 812 will drive a corresponding group of camshafts 83 to generate dynamic rotation. The group of camshafts 83 that generates dynamic rotation will drive the corresponding smooth grooves 85 and pitch-changing grooves 84 thereon to generate dynamic changes during the rotation process. Since the smooth grooves 85 are The vertical limit plate 88 is perpendicular to the corresponding connection. The dynamic rotation change in the smooth groove 85 is that the connecting rod 814 connected to it and fixed to the limit plate 88 keeps its position unchanged. When the pitch groove 84 rotates on the camshaft 83, it will also produce dynamic changes. The pitch groove 84 that produces dynamic changes will push the connecting rod 814 connected to it to produce height changes along the spiral trajectory of the pitch groove 84, thereby driving the limit plate 88 fixedly connected to the connecting rod 814 to produce height changes, so that the spacing between the multiple limit plates 88 distributed between a group of camshafts 83 changes, driving the mounting plate 81 fixed at one end of the limit plate 88 and the electrical automation equipment installed on the mounting plate 81 to produce synchronous spacing changes, so that the spacing between the equipment can be adjusted. During the adjustment, the first motor 78 drives the second gear 77 fixedly connected to the output end to rotate, and the rotating second gear 77 drives the first gear 76 meshed with one end to rotate. Due to the different number of teeth of the second gear 77 and the first gear 76, when the first motor 78 drives the second gear 77 to rotate, the second gear 77 drives the first gear 76 to rotate at an increased speed, and the rotating first gear 76 drives the connected vortex fan 715 to rotate at a high speed. The suction force generated by the rotation of the high-speed rotating vortex fan 715 drives the hot air flow emitted by the equipment in the inner cabinet 5 to be drawn into the exhaust pipe 71, and enters the heat conduction pipe 72 through the exhaust pipe 71. When the air flow flows along the heat conduction pipe 72 to the area where the refrigerant storage pipe 73 is located,The cold air emitted by the refrigerant in the refrigerant storage pipe 73 initially cools the hot air flow. When the initially cooled air flow enters the cooling box 74, it is further cooled by the multiple heat pipe heat dissipation modules 710 installed in the cooling box 74. When the completely cooled air flow contacts the multiple guide plates 711, it flows along the multiple guide plates 711 toward one end. When the air flow flows into the air supply pipe 716, it flows along the air supply pipe 716 toward the filter plate 717, passes through the filter plate 717, and flows along the outer shape of the dust cover 79 into the inner cabinet 5, thereby cooling the equipment inside the inner cabinet 5 that emits heat.
