Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and in particular relates to an adaptive multi-copper busbar low-voltage distribution cabinet. Background Technology

[0002] Multi-copper-busbar low-voltage distribution cabinet is an electrical device used in low-voltage power systems. It is mainly used to distribute electrical energy, protect circuits, and provide grounding or short-circuit protection. Its characteristics are the use of multiple copper busbars, which are used to connect the current conduction between different circuits. It has the advantages of good conductivity, high electrical safety, adaptability to diverse loads, and low electrical fault rate.

[0003] Typically, to prevent the heat generated by the internal wires and electrical components of a multi-copper busbar low-voltage distribution cabinet from being trapped inside during operation, a heat dissipation system is usually installed on the surface of the cabinet. This system uses a fan to draw outside air into the cabinet and then exhaust it, thus removing the heat from inside the cabinet. However, when the ambient temperature outside the cabinet is low and the load on the multi-copper busbar low-voltage distribution cabinet is small, and the internal cooling system can meet the cooling requirements, the continuously running fan leads to a waste of electrical energy. Furthermore, multi-copper busbar low-voltage distribution cabinets are mostly installed by fixing the bottom. Although this method provides high stability, when the upper side of the cabinet is subjected to external forces, the connection between the multi-copper busbar low-voltage distribution cabinet and the installation platform is prone to deformation or even breakage, making the connection between the multi-copper busbar low-voltage distribution cabinet and the installation platform easily damaged.

[0004] To address these issues, we provide an adaptive multi-copper busbar low-voltage distribution cabinet. Utility Model Content

[0005] The purpose of this utility model is to provide an adaptive multi-copper busbar low-voltage distribution cabinet. By using a thermometer and a proximity switch, the cooling fan is activated when the temperature reaches a preset range. Furthermore, the upper side of the cabinet is reinforced by a reinforcement mechanism. This solves the problems of existing technologies where the cabinet relies on passive cooling to meet the cooling requirements, resulting in wasted energy due to the continuously operating fan. Additionally, when the upper side of the cabinet is subjected to external forces, the connection between the multi-copper busbar low-voltage distribution cabinet and the installation platform is prone to deformation or even breakage, leading to easy damage at the connection point.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an adaptive multi-copper busbar low-voltage distribution cabinet, comprising an adaptive distribution cabinet, which includes a cabinet body. A proximity switch is fixedly mounted on the left wall inside the cabinet body. A thermometer is mounted to the left of the proximity switch. A rubber sleeve is mounted on the outer side of the lower end of the thermometer. A threaded sleeve is mounted on the outer side of the rubber sleeve. A threaded cap is threadedly connected to the outer side of the threaded sleeve. Reinforcing mechanisms are provided at the rear ends of the left and right side walls of the cabinet body. The reinforcing mechanisms include mounting plates fixed to the cabinet body. A screw is fixedly mounted on the rear wall of the mounting plate. A threaded sleeve is threadedly connected to the outer side of the screw. A circular plate is mounted on the outer side of the rear end of the threaded sleeve.

[0008] The present invention is further configured such that the upper side of the rubber sleeve is provided with through grooves in a circular array, and the lower wall of the threaded sleeve is fixed with a connecting plate that is fixed to the cabinet.

[0009] The present invention is further provided that ventilation holes are provided on both the upper and lower side walls of the cabinet, and a cooling fan is fixedly installed on the lower wall of the cabinet at the location of the ventilation hole.

[0010] The present invention is further provided that a dustproof net is fixedly provided on the lower wall of the cooling fan and the upper wall of the cabinet at the location of the ventilation hole, and a protective net is fixedly provided on the lower wall inside the cabinet at the location of the ventilation hole.

[0011] The present invention is further configured such that the circular plate is rotatably connected to the screw via a bearing, and the circular plate has perforations arranged in a circumferential array along its edge.

[0012] The present invention is further configured such that a bolt is threadedly connected to the front end of the screw, the inner end of the bolt abuts against the corresponding screw, and a reinforcing plate is fixedly provided on the front wall of the mounting plate, and the inner side wall of the reinforcing plate is fixedly connected to the cabinet.

[0013] The present invention is further provided with a mesh box on the lower wall inside the cabinet, and a desiccant is placed inside the mesh box.

[0014] The present invention is further provided that each of the four corner positions of the lower wall of the cabinet is fixedly provided with a support leg, and the lower end of the support leg is fixedly provided with a base plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention incorporates a thermometer and a proximity switch. When the temperature inside the cabinet rises, the liquid level inside the thermometer increases until the proximity switch detects that the liquid level has reached a preset height. At this point, the controller activates the cooling fan to dissipate heat. Compared to existing technologies, this design prevents the cooling fan from operating when the internal temperature of the cabinet has not reached the desired cooling temperature, and only initiates heat dissipation when the internal temperature reaches the desired temperature. This avoids wasting electrical energy and allows the adaptive multi-copper busbar low-voltage distribution cabinet to adapt to the internal temperature of the cabinet for heat dissipation.

[0017] This utility model, by setting up a reinforcement mechanism, allows the circular plate to be fixed to the wall with expansion bolts when the adaptive multi-copper busbar low-voltage distribution cabinet is installed on one side of the wall. This reinforcement mechanism strengthens the upper side of the cabinet. When the cabinet is subjected to external impact, the reinforcement mechanism and the connection between the adaptive multi-copper busbar low-voltage distribution cabinet and the installation platform share the force, making the adaptive multi-copper busbar low-voltage distribution cabinet more stable after installation and preventing deformation or even breakage at the connection between the adaptive multi-copper busbar low-voltage distribution cabinet and the installation platform to a certain extent.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-4 This utility model relates to an adaptive multi-copper busbar low-voltage distribution cabinet, comprising an adaptive distribution cabinet 1. The adaptive distribution cabinet 1 is a low-voltage distribution cabinet capable of automatically adjusting the internal temperature of the cabinet body 102. The adaptive distribution cabinet 1 includes a cabinet body 102, inside which control electrical components and multiple copper busbars are installed. The control electrical components, cabinet body 102, and cabinet door constitute the low-voltage distribution cabinet, which is existing technology and will not be described in detail here. A proximity switch 102b is fixedly installed on the left wall inside the cabinet body 102 to detect whether the liquid inside the thermometer 101 has reached the required heat dissipation height. The proximity switch 102b can be a capacitive proximity switch 102b, which can detect glass containers. The liquid level inside the device is determined by a thermometer 101 located to the left of the proximity switch 102b. The thermometer 101 can be a mercury thermometer. A rubber sleeve 108 is provided on the lower part of the thermometer 101. The diameter of the outer peripheral wall of the upper side of the rubber sleeve 108 gradually decreases from top to bottom. A threaded sleeve 107 is provided on the outside of the rubber sleeve 108. The bottom of the rubber sleeve 108 is interference-fitted with the threaded sleeve 107 to improve the connection stability between the rubber sleeve 108 and the threaded sleeve 107. A threaded cap 107a is threadedly connected to the outside of the threaded sleeve 107. A hole is opened in the middle of the upper wall of the threaded cap 107a. The thermometer 101 passes through the hole on the threaded cap 107a and is located above the hole.

[0029] Specifically, the upper side of the rubber sleeve 108 is provided with grooves 108a in a circular array. The grooves 108a can increase the deformation range of the rubber sleeve 108, so as to securely clamp and fix the thermometer 101. The lower wall of the threaded sleeve 107 is fixed with a connecting plate 102f that is fixed to the cabinet 102.

[0030] Ventilation holes 102e are provided on both the upper and lower side walls of the cabinet 102 for airflow during heat dissipation. A cooling fan 106 is fixed at the location of the ventilation hole 102e corresponding to the lower wall of the cabinet 102. When the cooling fan 106 is working, outside air enters the interior of the cabinet 102 through the ventilation hole 102e at the bottom of the cabinet 102 and is then discharged through the ventilation hole 102e at the top of the cabinet 102.

[0031] Dustproof nets 102a are fixedly installed on the lower wall of the cooling fan 106 and the upper wall of the cabinet 102 at the location of the ventilation hole 102e to prevent external dust from entering the interior of the cabinet 102. A protective net 102c is fixedly installed on the lower wall of the interior of the cabinet 102 at the location of the ventilation hole 102e. The protective net 102c is made of metal to improve protection. The protective net 102c is designed to prevent items from falling and coming into contact with the fan blades in the cooling fan 106 and causing damage.

[0032] It should be noted that the side wall of the cabinet 102 is also provided with slots for wire introduction and exit (not shown in the figure). The proximity switch 102b and the cooling fan 106 are both electrically connected to the microcontroller in the controller through conductive wires. The microcontroller in the controller is electrically connected to the external power supply through conductive wires. At the same time, the proximity switch 102b, the cooling fan 106 and the controller are all existing technologies and can be obtained from the market or through private customization. Their models are not limited here.

[0033] The operation process of this embodiment is as follows: When in use, the proximity switch 102b monitors the liquid in the thermometer 101 in real time. When the temperature inside the cabinet 102 rises, the liquid in the thermometer 101 expands, causing the liquid level to rise. When the proximity switch 102b detects that the preset height has been reached, the controller controls the cooling fan 106 to work. At this time, outside air enters the cabinet 102 through the ventilation hole 102e at the bottom of the cabinet 102, and then carries heat through the ventilation hole 102e at the top of the cabinet 102 to complete the heat dissipation.

[0034] When the temperature inside the cabinet 102 drops, the proximity switch 102b detects that the liquid level in the thermometer 101 has dropped below a preset height, and the controller controls the cooling fan 106 to stop working.

[0035] Example 2

[0036] Please see Figure 1 , 2 3 and 5 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the rear ends of the left and right side walls of the cabinet 102 are provided with a reinforcing mechanism 2 for reinforcing the cabinet 102. The reinforcing mechanism 2 includes an installation plate 204 fixed to the cabinet 102. A screw 203 is fixed to the rear wall of the installation plate 204. A screw sleeve 202 is threaded to the outside of the screw 203. A circular plate 201 is provided on the outside of the rear end of the screw sleeve 202. The circular plate 201 is fixed to the wall by bolts 202b. At the same time, the cooperation between the screw 203 and the screw sleeve 202 makes the distance between the circular plate 201 and the installation plate 204 adjustable, which facilitates the smooth fit of the circular plate 201 to the wall.

[0037] Specifically, the circular plate 201 is rotatably connected to the screw 203 via the bearing 202a, so that the screw 203 can rotate relative to the circular plate 201. The circular plate 201 has through holes arranged in a circumferential array along its edge to provide installation space for the screw.

[0038] The front end of the screw 203 is threaded with a bolt 202b. The inner end of the bolt 202b abuts against the corresponding screw 203. After installation, the bolt 202b can prevent the screw sleeve 202 from rotating relative to the screw 203. The front wall of the mounting plate 204 is fixed with a reinforcing plate 204a, which can improve the structural stability between the mounting plate 204 and the cabinet 102. The inner side wall of the reinforcing plate 204a is fixedly connected to the cabinet 102.

[0039] The lower wall inside the cabinet 102 is provided with a mesh box 104, and the inside of the mesh box 104 is provided with a desiccant 103 to absorb moisture inside the cabinet 102.

[0040] Support legs 102d are fixed at the four corners of the lower wall of cabinet 102. A base plate 105 is fixed at the lower end of the support legs 102d. Screw holes (not shown in the figure) are also provided on the base plate 105 for screws to pass through and be fixed to the mounting platform.

[0041] The operation process of this embodiment is as follows: the base plate 105 can be fixed on the installation platform by screws, then the screw sleeve 202 is rotated. At this time, the front and rear positions of the screw sleeve 202 change until the rear wall of the round plate 201 abuts against the wall. With the cooperation of the expansion screw and the through hole, the round plate 201 is fixed on the wall. Then the bolt 202b is tightened.
