Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to an incoming line cabinet with automatic internal temperature regulation. Background Technology

[0002] A switchgear is an electrical device. External lines first enter the main control switch inside the cabinet, then the branch control switches, with each branch circuit configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments, and high-voltage busbars, such as in power plants. Some also have underfrequency load shearing features to protect key equipment. Switchgear can be classified by application as incoming line cabinets, outgoing line cabinets, metering cabinets, compensation cabinets (capacitor cabinets), corner cabinets, and busbar cabinets.

[0003] Because the incoming line cabinet contains a large number of load-bearing line transfer devices, it generates a lot of heat during operation. In order to stabilize the normal operation of the lines, when the temperature inside the cabinet is too high, the current method is to start the fan through an automatic temperature regulation device to sense and cool the temperature, so as to ensure the stable operation of each line inside the cabinet. However, the existing incoming line cabinets do not take effective dust prevention into account, which means that the dust carried by the fan when it delivers airflow into the cabinet cannot be collected and cleaned in time, resulting in problems with the operation of subsequent circuits. Therefore, there is an urgent need for an incoming line cabinet with automatic temperature regulation inside the cabinet. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an incoming line cabinet with automatic temperature regulation inside the cabinet. It has advantages such as centralized and rapid dust removal and ensuring smooth circuit operation. It solves the problem that existing incoming line cabinets do not adequately consider effective dust prevention, resulting in the inability to promptly and centrally remove dust carried by the fan when delivering airflow into the cabinet, which leads to problems in the operation of subsequent circuits.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an inlet cabinet with automatic temperature regulation, comprising an inlet cabinet body and a temperature sensor, wherein the temperature sensor is fixedly connected to the inside of the inlet cabinet body, the inside of the inlet cabinet body is provided with an air-cooling mechanism, and the inside of the inlet cabinet body is also provided with a dust collection mechanism.

[0008] The air-cooling mechanism includes an air duct, an air mesh frame is provided on one side of the air duct, a quick-release assembly is provided between the air duct and the air mesh frame, the air duct is movably connected to the air mesh frame through the quick-release assembly, a fan frame is fixedly connected inside the air mesh frame, and a fan is fixedly connected inside the fan frame.

[0009] The dust collection mechanism includes a dust removal chamber, a dust collection concave plate is hinged inside the dust removal chamber, a number of air outlet holes are opened on the outer wall of the dust collection concave plate, a dust filter cotton is fixedly connected inside the dust collection concave plate, and a dust scraper is provided inside the dust collection concave plate on the outer wall of the dust filter cotton.

[0010] Preferably, the air duct is fixedly connected to the outer wall of the incoming line cabinet, and the air duct is connected to the incoming line cabinet.

[0011] The duct is used to draw air into the incoming line cabinet.

[0012] Preferably, the outer wall of the air mesh frame is adapted to the inner wall of the opening of the air duct, and the air mesh frame is located inside the inlet cabinet.

[0013] Preferably, the quick-release assembly includes four insertion holes and four insertion rods. The four insertion holes are respectively opened on two opposite surfaces of the inner sidewall of the duct near both ends. The four insertion rods are respectively movably connected to two opposing surfaces of the outer sidewall of the air mesh frame near both ends. The insertion holes and insertion rods are interlocked.

[0014] Since the fan needs to run continuously, it needs to be inspected and maintained regularly to ensure its stability. Therefore, to facilitate inspection and maintenance, the air duct and the air mesh frame are connected by plug-in holes and plug-in rods, which facilitates disassembly and assembly and improves efficiency.

[0015] Preferably, a spring cavity is provided on the outer wall of the wind mesh frame near the four plug-in rods. One end of each of the four plug-in rods is inserted into the interior of the four spring cavities, and the other end of each of the four plug-in rods extends outside the four spring cavities.

[0016] Preferably, each of the four insertion rods has a stop block fixedly connected to one end of the insertion rod located inside the spring cavity. The stop block is slidably connected to the spring cavity. A spring is sleeved on the outer wall of the insertion rod, and the spring is located inside the spring cavity.

[0017] Preferably, the dust removal chamber is located on the outer wall of the inlet cabinet opposite to the fan, the dust collection concave plate protrudes outward from the outer wall of the inlet cabinet, and the dust collection concave plate is connected to the filter cotton by bolts.

[0018] The filter cotton can be easily installed and removed from the dust collection plate using bolts, making it convenient to replace and clean the filter cotton.

[0019] Preferably, the inner sidewall of the dust collection plate is provided with sliding grooves on two opposite surfaces, and sliding rods are fixedly connected inside the two sliding grooves. The two ends of the dust scraper are slidably connected to the two sliding rods.

[0020] When the dust filter needs cleaning, open the dust collection recess and push the dust scraper up and down. The surface of the dust scraper should be in contact with the surface of the dust filter. Pushing the dust scraper up and down will scrape the surface of the dust filter, making it convenient, quick and easy to clean the surface of the dust filter.

[0021] Preferably, the dust collection mechanism further includes a sealing plate, which is disposed on the inner side wall of the inlet cabinet near the dust removal chamber. Two U-shaped guide rails are fixedly connected to the inner side wall of the inlet cabinet, and the sealing plate is disposed between the two U-shaped guide rails. The sealing plate is slidably connected to the two U-shaped guide rails.

[0022] To prevent dust from falling into the inlet cabinet and affecting the wiring when cleaning the surface of the filter cotton, after opening the dust collection recess, push the sealing plate so that the sealing plate slides along the U-shaped guide rail to the dust removal chamber to seal the dust removal chamber, prevent dust from entering the inlet cabinet and improve the dust removal effect.

[0023] Compared with the prior art, the present invention provides an incoming line cabinet with automatic temperature regulation inside the box, which has the following beneficial effects:

[0024] 1. This incoming line cabinet features automatic temperature regulation. A temperature sensor detects the internal temperature of the cabinet. When the temperature is too high, the fan activates, blowing air through the wiring to cool it down. Dust carried by the airflow is blown onto the filter cotton, which traps the dust. The air outlet allows for airflow. Once the dust on the filter cotton reaches a certain level, the dust collection plate is opened, and a scraper is used to remove the dust, thus cleaning the cabinet and preventing it from spreading and affecting the wiring. This ensures stable and reliable operation of the wiring within the cabinet.

[0025] 2. The temperature-regulating incoming line cabinet inside the box is in a contracted state due to the spring. The spring is fixedly connected to the stop block. The spring pulls the stop block to move outward from the spring cavity, and the plug rod fixed to the stop block moves accordingly, thus automatically engaging with the plug hole. When disassembly is required, simply press the plug rod to extend the spring and remove the plug rod from the plug hole, which is convenient and quick. Attached Figure Description

[0039] The dust collection mechanism 4 includes a dust collection chamber 401, a dust collection concave plate 402 is hinged inside the dust collection chamber 401, a number of air outlet holes 403 are opened on the outer side wall of the dust collection concave plate 402, a dust filter cotton 404 is fixedly connected inside the dust collection concave plate 402, and a dust scraper 405 is provided inside the dust collection concave plate 402 on the outer side wall of the dust filter cotton 404.

[0040] Through the above technical solution, the temperature sensor 2 is electrically connected to the fan 305. The temperature sensor 2 senses the temperature inside the incoming line cabinet 1. When the temperature inside the incoming line cabinet 1 is too high, the fan 305 is activated. The fan 305 blows air to cool down the circuits inside the incoming line cabinet 1. The dust carried by the air is blown onto the dust filter cotton 404. The dust filter cotton 404 traps the dust in the air, causing the dust to adhere to the filter cotton 404. The air outlet 403 allows airflow. When the dust on the dust filter cotton 404 accumulates to a certain extent, the dust collection concave plate 402 is opened, and the dust scraper 405 is used to scrape off the dust on the dust filter cotton 404, thereby cleaning the dust in a concentrated manner and preventing the dust from spreading and affecting the operation of the circuits inside the incoming line cabinet 1, ensuring the stable and reliable operation of the circuits inside the incoming line cabinet 1.

[0041] Specifically, the air duct 301 is fixedly connected to the outer wall of the incoming line cabinet 1, and the air duct 301 is connected to the incoming line cabinet 1.

The four insertion rods 3032 are respectively movably connected to two opposite surfaces of the outer side wall of the air mesh frame 302 near the two ends. The insertion holes 3031 and the insertion rods 3032 are interlocked.

[0045] With the above technical solution, since the fan 305 needs to run continuously, it needs to be inspected and maintained regularly in order to ensure its stability. Therefore, in order to facilitate inspection and maintenance, the air duct 301 and the air mesh frame 302 are movably connected through the plug hole 3031 and the plug rod 3032, which facilitates disassembly and assembly and improves efficiency.

[0046] Specifically, spring cavities 3033 are provided on the outer side wall of the wind mesh frame 302 near the four plug-in rods 3032. One end of each of the four plug-in rods 3032 is inserted into the interior of the four spring cavities 3033, and the other end of each plug-in rod extends out of the four spring cavities 3033.

[0047] Specifically, each of the four plug rods 3032 has a stop block 3034 fixedly connected to one end of the plug rod 3032 located inside the spring cavity 3033. The stop block 3034 is slidably connected to the spring cavity 3033. A spring 3035 is sleeved on the outer wall of the plug rod 3032. The spring 3035 is located inside the spring cavity 3033.

[0048] With the above technical solution, the spring 3035 is in a contracted state in its natural state. The spring 3035 is fixedly connected to the stop block 3034. The spring 3035 pulls the stop block 3034 to move outward from the spring cavity 3033. The insertion rod 3032, which is fixed to the stop block 3034, moves accordingly, thereby automatically maintaining a locking state with the insertion hole 3031. When disassembly is required, simply press the insertion rod 3032 to extend the spring 3035, and the insertion rod 3032 will exit the insertion hole 3031, which is convenient and quick.

[0049] Specifically, the dust collection chamber 401 is located on the outer side wall of the inlet cabinet 1, opposite to the fan 305. The dust collection recess 402 protrudes outward from the outer side wall of the inlet cabinet 1, and the dust collection recess 402 and the filter cotton 404 are connected by bolts.

[0050] With the above technical solution, the dust filter cotton 404 can be installed and removed from the dust collection concave plate 402 at any time by means of bolts, which makes it convenient to replace and clean the dust filter cotton 404.

[0051] Specifically, the inner wall of the dust collection plate 402 has two opposite surfaces with grooves 406, and the inside of the two grooves 406 is fixedly connected with a sliding rod 407. The two ends of the dust scraper 405 are slidably connected to the two sliding rods 407.

[0052] With the above technical solution, when it is necessary to clean the dust filter cotton 404, the dust collection concave plate 402 is opened, and the dust scraper 405 is pushed up and down. The surface of the dust scraper 405 should be in contact with the surface of the dust filter cotton 404. When the dust scraper 405 is pushed up and down, it can scrape the surface of the dust filter cotton 404, which is convenient, quick and easy to complete the cleaning of the surface of the dust filter cotton 404.

The sealing plate 409 is disposed between the two U-shaped guide rails 410 and is slidably connected to the two U-shaped guide rails 410.

[0054] Through the above technical solution, in order to prevent dust from falling into the inlet cabinet 1 and affecting the circuit when cleaning the surface of the filter cotton 404, after opening the dust collection recess 402, the sealing plate 409 is pushed so that the sealing plate 409 slides along the U-shaped guide rail 410 to the dust removal chamber 401 to seal the dust removal chamber 401, prevent dust from entering the inlet cabinet 1 and improve the dust removal effect.
