Description

Technical Field

[0001] This utility model relates to the field of electrical instrument cabinet technology, and in particular to an electrical instrument cabinet with good protection effect. Background Technology

[0002] An electrical instrument cabinet is a metal cabinet or box used to install and protect various electrical instruments and equipment. It is mainly used for centralized monitoring, control and display of various parameters and operating status in electrical systems. As a key facility for centralized installation and protection of electrical instruments, control components and other equipment, electrical instrument cabinets are widely used in various field environments such as industrial automation and power systems. These environments often have problems such as high dust concentration, large temperature and humidity changes or small space, which pose a serious challenge to the long-term stable operation of the equipment in the cabinet.

[0003] Traditional instrument cabinets generally use a structure with fixed heat dissipation holes and simple filters, which has significant drawbacks: First, the static heat dissipation method results in a single and inefficient airflow path inside the cabinet, and the heat generated by the equipment operation is prone to accumulate in localized hot spots, accelerating the aging and failure of electronic components; Second, the filters are easily clogged in dusty environments, which not only rapidly reduces heat dissipation efficiency and increases energy consumption, but also requires frequent manual shutdowns for cleaning and maintenance, greatly increasing operation and maintenance costs and equipment downtime; Third, the internal space of the cabinet lacks scientific zoning, especially the frequently used touch display area, which lacks effective physical isolation from the internal instrument components, making it prone to vibration interference or accidental contact risks during daily operation. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides an electrical instrument cabinet with good protection effect, which has heat dissipation, dust prevention and protection effects.

[0005] The technical solution adopted by this utility model is as follows: it includes a cabinet placed on the ground, the top of the cabinet has an air vent, a fixed frame is fixed to the top of the cabinet, a movable component is fixedly installed on the inner wall of the top of the fixed frame, a filter-type heat dissipation component is fixedly installed on one side of the cabinet, a synchronous wheel is fixedly installed on both the movable component and the filter-type heat dissipation component, a synchronous belt is provided between the two synchronous wheels, and a first partition is fixed inside the cabinet.

[0006] Preferably, in order to divide the internal space of the cabinet into two parts to facilitate the classified installation of electrical instruments and moving components, the front side of the cabinet is hinged with a first cabinet door and a second cabinet door, the first partition is located between the first cabinet door and the second cabinet door, and a touch screen display panel is installed on the second cabinet door.

[0007] Preferably, in order to classify and install electrical instruments with different functions, three second partitions are fixed inside the cabinet.

[0008] Preferably, in order to drive one end of the branch pipe to move up and down and improve the heat dissipation effect inside the cabinet, the moving component includes a motor for driving and a screw with threads on the outside. The motor is fixedly installed on the top inner wall of the fixed frame, the top of the screw is installed on the output end of the motor, the top of the screw is rotatably installed on the bottom inner wall of the cabinet, a slider is slidably installed on the outside of the screw, and an air duct is fixedly installed on the slider. The other end of the air duct is fixed inside the cabinet.

[0009] Preferably, in order to limit the slider, a guide rod is fixed between the inner wall of the top and the inner wall of the bottom of the cabinet, and the slider is slidably disposed on the outside of the guide rod.

[0010] Preferably, in order to filter the circulating air, the filter-type heat dissipation assembly includes an outer frame and a filter plate for filtering dust. One side of the outer frame is fixedly installed on one side of the cabinet. The inner top and bottom walls of the outer frame are provided with sliding grooves. The filter plate is disposed between the two sliding grooves. A rotating shaft is rotatably installed on the inner bottom wall of the outer frame. The other end of the rotating shaft passes through the top of the outer frame and is located above the outer frame.

[0011] Preferably, to accelerate the air exchange speed inside and outside the cabinet, blades and teardrop-shaped abutment rods are fixedly installed on the outside of the rotating shaft.

[0012] Preferably, in order to vibrate and clean the filter plate, a spring is fixed on one side of the slide groove, and the other end of the spring is fixedly installed on one side of the filter plate.

[0013] The beneficial effects of this utility model are as follows: By combining the moving component and the filter-type heat dissipation component, multiple protections and efficient heat dissipation are synergistically optimized. The moving component drives the air duct to sweep up and down along the guide rod, and combined with the filter-type heat dissipation component driven by the synchronous belt, the heat dissipation airflow covers the entire cabinet space, avoiding local overheating and providing good protection for the inside of the cabinet. Moreover, the filter plate is pre-tightened by the spring in the slide groove, and with the centrifugal force of the rotating blades and the periodic impact of the teardrop-shaped contact rod, the dust is vibrated and detached and the airflow backflow achieves self-cleaning, effectively preventing blockage and extending the maintenance cycle. At the same time, the cabinet door and multi-level partitions not only isolate the operation of the touch screen display panel, but also improve the space utilization rate, making it highly practical.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, this embodiment provides an electrical instrument cabinet with good protection, including a cabinet 1 placed on the ground. The top of the cabinet 1 has an air vent 2, through which hot air inside the cabinet 1 can flow out. A fixed frame 3 is fixed to the top of the cabinet 1, which improves the stability of the moving component 4 during operation. The moving component 4 is fixedly installed on the inner wall of the top of the fixed frame 3. A filter-type heat dissipation component 5 is fixedly installed on one side of the cabinet 1. Synchronous pulleys 6 are fixedly installed on both the moving component 4 and the filter-type heat dissipation component 5. A synchronous belt 7 is provided between the two synchronous pulleys 6. A first partition 9 is fixed inside the cabinet 1.

[0022] The cabinet 1 has a first cabinet door 8 and a second cabinet door 10 hinged to the front, which facilitates the inspection and installation of electrical instruments inside the cabinet 1. A first partition 9 is located between the first cabinet door 8 and the second cabinet door 10. A touch screen display panel 11 is installed on the second cabinet door 10. Three second partitions 12 are fixed inside the cabinet 1. The three second partitions 12 divide the internal space of the cabinet 1 into different areas, so that different types of electrical instruments can be installed separately, which improves the utilization rate of the internal space of the cabinet 1 and avoids mutual interference between electrical instruments.

[0023] In actual use, the operator can control the electrical instruments inside the cabinet 1 through the touch screen display panel 11. The touch screen display panel 11 is connected to the electrical instruments inside the cabinet 1 through wires. Then, by using the moving component 4 and the filter-type heat dissipation component 5, efficient heat dissipation and dust protection can be achieved inside the cabinet 1, so that the heat dissipation airflow covers the entire space of the cabinet 1, avoiding local overheating and providing good protection for the inside of the cabinet 1. This effectively extends the service life of the electrical instruments. Moreover, under the action of the synchronous pulley 6 and the synchronous belt 7, the moving component 4 and the filter-type heat dissipation component 5 can operate synchronously, enhancing the overall coordination and stability of operation. At the same time, the first partition 9 and the second partition 12 can divide the internal space of the cabinet 1, allowing electrical instruments with different functions to be installed separately, which is convenient for subsequent maintenance and replacement, and improves the flexibility of the use of the electrical instrument cabinet.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the moving component 4 includes a motor 401 for driving and a screw 402 with threads on the outside. The motor 401 is fixedly installed on the top inner wall of the fixed frame 3. The top of the screw 402 is installed on the output end of the motor 401 and the top of the screw 402 is rotatably installed on the bottom inner wall of the cabinet 1. A slider 403 is slidably installed on the outside of the screw 402. A duct 404 is fixedly installed through the slider 403. One end of the duct 404 can move with the movement of the slider 403, and the other end of the duct 404 is fixed inside the cabinet 1. A guide rod 405 is fixed between the top inner wall and the bottom inner wall of the cabinet 1. The slider 403 is slidably disposed outside the guide rod 405.

[0025] In use, the motor 401 drives the screw 402 to rotate. Since the screw 402 has a thread on its outer side and the guide rod 405 guides and limits the slider 403, the slider 403 can move up and down on the screw 402, thereby driving the air duct 404 to sweep up and down, which improves the heat dissipation effect inside the cabinet 1, avoids local overheating inside the cabinet 1, prevents the air duct 404 from shaking when moving, and improves the stability of the air duct 404 during operation.

[0026] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the filter-type heat dissipation assembly 5 includes an outer frame 501 and a filter plate 503 for filtering dust. One side of the outer frame 501 is fixedly installed on one side of the cabinet 1. The inner walls of the top and bottom of the outer frame 501 are provided with sliding grooves. The filter plate 503 is disposed between the two sliding grooves. The top and bottom of the filter plate 503 can slide inside the sliding grooves. A rotating shaft 504 is rotatably installed on the inner wall of the bottom of the outer frame 501. The other end of the rotating shaft 504 passes through the top of the outer frame 501 and is located above the outer frame 501. A blade 505 and a teardrop-shaped abutment rod 506 are fixedly installed on the outside of the rotating shaft 504. A spring 502 is fixed on one side of the sliding groove. The other end of the spring 502 is fixedly installed on one side of the filter plate 503.

[0027] In use, air is filtered through the filter plate 503, effectively preventing dust from entering the cabinet 1 and ensuring the normal operation of the electrical instruments inside the cabinet 1. Simultaneously, the rotating shaft 504 rotates under the action of the synchronous belt 7 and synchronous pulley 6, causing the blades 505 and teardrop-shaped contact rods 506 to rotate with the shaft 504. The rotation of the blades 505 accelerates the air exchange speed inside and outside the cabinet 1, while the teardrop-shaped contact rods 506 periodically impact the filter plate 503 as the shaft 504 rotates. Combined with the pre-tightening effect of the spring 502 on the filter plate 503, this achieves vibration cleaning of the filter plate 503, allowing dust adhering to it to be vibrated off. This effectively prevents the filter plate 503 from clogging, improves heat dissipation efficiency, reduces the frequency of manual downtime for cleaning and maintenance, lowers operating costs, and extends the service life of the electrical instrument cabinet.
