Abstract
Description
Technical Field
[0001] This utility model belongs to the field of control cabinet technology, specifically a low-voltage electrical integrated control cabinet with overheat protection function. Background Technology
[0002] Low-voltage electrical integrated control cabinets are the core hubs that ensure stable power supply and orderly equipment operation. Heat is generated during the operation of low-voltage electrical integrated control cabinets.
[0003] The lack of an active heat dissipation mechanism means that electrical components will be in an overheated state for a long time, which will accelerate the aging process of the components. High temperature will cause their performance to decline rapidly, and the control cabinet will become unstable due to overheating. Moreover, the internal structure design of control cabinets, which mostly adopts fixed beams and fixed mounting plates, is difficult to adjust according to the installation requirements of different specifications of components. This results in low utilization of the internal space of the cabinet and affects the use effect. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a low-voltage electrical integrated control cabinet with overheat protection function, which solves the problem that the internal structure design of control cabinets, which mostly adopts fixed crossbeams and fixed mounting plates, is difficult to adjust according to the subsequent installation requirements of different specifications of components, resulting in low utilization of the internal space of the cabinet.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage electrical integrated control cabinet with overheat protection function, comprising a cabinet body, a base installed at the bottom of the cabinet body, and a ventilation hood connected to the top of the cabinet body. A top cover is provided above the ventilation hood and is fixed to the top of the cabinet body. Columns are fixed at the four corners inside the cabinet body, and several locking holes are provided in the columns. Several trays are slidably installed between the four columns, and several through holes are provided in the trays. An adjustment assembly is installed at the bottom of the trays. The adjustment assembly includes a vertical rod, one end of which passes through the front side of the tray and is fixed with a handle. Two connecting rods are rotatably connected to both sides of the vertical rod via pins. The other end of the connecting rod is rotatably connected to a locking assembly via a pin. The locking assembly includes a locking rod, one end of which passes through the tray and is engaged in a locking hole. Two baffles slide through the two locking rods on the same side, and the baffles are fixed to the bottom of the tray.
[0006] As a further embodiment of this utility model: filter screens are installed on the front and rear sides of the base, and cabinet doors are installed on the front and rear sides of the cabinet.
[0007] As a further embodiment of this utility model: heat exhaust fans are installed on both sides of the interior of the cabinet, and several ventilation holes are opened on both sides of the exterior of the cabinet corresponding to the positions of the two heat exhaust fans.
[0008] As a further embodiment of this utility model: a temperature sensing module is installed inside the cabinet on the side near the cabinet door, and a round hole is opened at the bottom of the inner wall of the cabinet and communicates with the inside of the base.
[0009] As a further embodiment of this utility model: a telescopic rod is fixedly connected to the end of the upright rod away from the handle, and the end of the telescopic rod is fixed to the inner wall of the cabinet.
[0010] As a further embodiment of this utility model: the clamping rod is rectangular in design and is fitted with a spring on the outside. One end of the spring is fixed to one side of the baffle, and the other end is fixed to the outside of the clamping rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-voltage electrical integrated control cabinet with overheat protection uses trays to support low-voltage electrical components. When adjusting the distance between two adjacent trays, the operator holds the handle and pulls the upright. The upright moves through the tray and extends the telescopic rod. During the movement of the upright, the connecting rods on both sides, connected by pins, rotate synchronously. The other end of the connecting rod moves the locking lever in the locking assembly until the lever disengages from the locking hole in the upright, releasing the locking between the tray and the upright. Next, the tray is raised or lowered to adjust its position. After adjustment, the handle is released, and the spring force supports the levers, causing the two levers on both sides to move away from each other and engage with the corresponding height locking holes, thus locking the tray position. This completes the adjustment of the distance between the two trays, allowing for adjustments based on the installation requirements of components of different specifications, improving the utilization of the cabinet's internal space and enhancing the overall effectiveness of the control cabinet.
[0012] This low-voltage electrical integrated control cabinet with overheat protection achieves passive cooling by allowing the heat generated by the electrical components to be expelled through ventilation holes on both sides of the cabinet, the base, and the top ventilation hood. Simultaneously, a temperature sensing module inside the cabinet monitors the internal temperature in real time. When the module detects that the internal temperature exceeds a preset safety threshold, it triggers the exhaust fan to start, expelling hot air through corresponding ventilation holes on the outside of the cabinet. The ventilation hood, in conjunction with the top cover, guides cool external air through the base filter, into the cabinet via the bottom hole, and then circulates between components through the through-holes on the support plate, forming a complete air circulation cooling path. This active cooling method rapidly reduces the internal temperature, preventing overheating-related malfunctions of the electrical components and improving the stability of the control cabinet's operation.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0015] like Figure 1-5 As shown, this utility model provides a technical solution: a low-voltage electrical integrated control cabinet with overheat protection function, including a cabinet body 1, a base 2 installed at the bottom of the cabinet body 1, filters 5 installed on the front and rear sides of the base 2 respectively, and cabinet doors 8 installed on the front and rear sides of the cabinet body 1 respectively. The cabinet doors 8 on the front and rear sides of the cabinet body 1 can be opened and closed, which facilitates the installation, inspection and maintenance of electrical components, and when closed, it can provide a dustproof and protective closed environment for the components inside the cabinet, reducing the interference of the external environment on the operation of the components. Furthermore, the top of the cabinet 1 is connected to a ventilation hood 4, and a top cover 3 is provided above the ventilation hood 4. The top cover 3 is fixed to the top of the cabinet 1. Heat exhaust fans 7 are installed on both sides inside the cabinet 1, and several ventilation holes 6 are opened on both sides outside the cabinet 1 corresponding to the positions of the two heat exhaust fans 7. A temperature sensing module 9 is installed inside the cabinet 1 on the side near the cabinet door 8. When the temperature sensing module 9 detects that the temperature inside the cabinet exceeds the preset safety threshold, it will trigger the heat dissipation fan 7 to start, accelerating the air flow inside the cabinet. A round hole is opened at the bottom of the inner wall of the cabinet 1 and is connected to the inside of the base 2. The filters 5 on the front and back sides of the base 2 can filter impurities in the air entering the cabinet, preventing dust and other accumulations from affecting the operation of electrical components and heat dissipation structure. At the same time, the round hole at the bottom of the cabinet 1 is connected to the inside of the base 2, forming a bottom ventilation channel to allow external air to enter the cabinet 1.
[0016] Uprights 10 are fixed at the four corners inside the cabinet 1. Several locking holes 11 are opened in the uprights 10. Several support plates 12 are slidably installed between the four uprights 10. Several through holes 13 are opened in the support plates 12. An adjustment component 14 is installed at the bottom of the support plate 12. The adjustment component 14 includes an upright 141. One end of the upright 141 passes through the front side of the support plate 12 and is fixed with a handle 142. The end of the upright 141 away from the handle 142 is fixedly connected to a telescopic rod 143. The end of the telescopic rod 143 is fixed to the inner wall of the cabinet 1. The upright 141 moves at the through position on the front side of the support plate 12 and drives the telescopic rod 143 to retract, which plays a supporting and guiding role for the upright 141 and improves the stability of the movement of the upright 141. Two connecting rods 144 are rotatably connected to both sides of the upright 141 via pins. The other end of the connecting rod 144 is rotatably connected to a locking assembly 15 via a pin. The locking assembly 15 includes a locking rod 151. One end of the locking rod 151 passes through the support plate 12 and is engaged in the locking hole 11. Two baffles 16 slide through the two locking rods 151 on the same side. The baffles 16 are fixed to the bottom of the support plate 12, which not only provide sliding guidance for the locking rods 151 and prevent the locking rods 151 from shifting and affecting the locking effect, but also provide a rectangular design for the locking rods 151. A spring 152 is sleeved on the outside of the spring. One end of the spring 152 is fixed to one side of the baffle 16, and the other end is fixed to the outside of the locking rod 151. The spring force of the spring 152 supports the locking rod 151, so that the two locking rods 151 on both sides move away from each other. At this time, the locking rods 151 reset and engage in the locking hole 11 at the corresponding height, so as to lock the position of the support plate 12.
[0017] The working principle of this utility model is as follows: When the control cabinet is cooled, the heat generated by the electrical components installed on the tray 12 can be discharged through the ventilation holes 6 on both sides of the cabinet 1, the base 2, and the ventilation hood 4 on top, thus achieving the purpose of passive heat dissipation. At the same time, the temperature sensing module 9 inside the cabinet 1 monitors the temperature data inside the cabinet 1 in real time. When the temperature sensing module 9 detects that the temperature inside the cabinet exceeds the preset safety threshold, it will trigger the heat dissipation fan 7 to start, accelerate the air flow inside the cabinet, and discharge the high temperature air through the ventilation holes 6 at the corresponding positions outside the cabinet 1. The ventilation hood 4 cooperates with the top cover 3 to guide the external cold air into the cabinet 1 through the filter screen 5 of the base 2, and then into the cabinet 1 through the bottom round hole. It then circulates between the components through the through holes 13 on the tray 12, forming a complete air circulation heat dissipation path, and quickly reducing the temperature inside the cabinet through active heat dissipation. When adjusting the distance between two adjacent pallets 12, the operator holds the handle 142 and pulls the upright rod 141. The upright rod 141 moves to the through position on the front side of the pallet 12 and causes the telescopic rod 143 to extend. During the movement of the upright rod 141, the connecting rods 144 connected by pins on both sides rotate synchronously. The other end of the connecting rod 144 drives the locking rod 151 in the locking assembly 15 to move. The locking rod 151 slides through the baffle 16, providing a sliding guide for the locking rod 151 and preventing the locking rod 151 from deviating. Continue until the locking rod 151 disengages from the locking hole 11 in the column 10, releasing the locking state between the support plate 12 and the column 10. Next, lift or lower the support plate 12 to adjust its position. After the adjustment is completed, release the handle 142. The spring force of the spring 152 supports the locking rod 151, causing the two locking rods 151 on both sides to move away from each other. At this time, the locking rod 151 resets and engages in the corresponding height locking hole 11, completing the position locking of the support plate 12. This completes the adjustment of the distance between the two support plates 12.
