Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically to an external electrical control cabinet. Background Technology

[0002] The comet-type filtration system is an advanced rapid deep filtration technology with comet-type fiber filter media as its core. The comet-type fiber filter media has an asymmetric fractal structure, with one end being a loose bundle of fibers called the "comet tail" and the other end being fixed in a denser "comet nucleus". It can adaptively form a filter bed that is close to an ideal state in the filter. This makes the comet-type filtration system have the advantages of high filtration accuracy and large dirt interception capacity of fiber filter media, as well as the advantages of high backwashing cleanliness and low water consumption of granular filter media.

[0003] Comet-type filtration systems rely on an external electrical control cabinet to control operations such as start-up, shutdown, filtration speed adjustment, and backwash cycle setting. Therefore, the control cabinet is crucial for the stable operation of the system. However, existing control cabinets have some shortcomings: the current mainstream heat dissipation method relies on ventilation holes or fans to dissipate heat throughout the cabinet. However, in practical applications, due to the complex electrical control requirements of comet-type filtration systems, electrical components inside the cabinet are often densely packed. In particular, heat-generating components such as power modules and relays are often too close together due to their compact layout, resulting in poor airflow between components and difficulty in dissipating heat. After prolonged operation, the local temperature rises sharply, seriously affecting the performance stability and service life of the electrical components. Utility Model Content

[0004] The purpose of this utility model is to provide an external electrical control cabinet that can adjust the distance between electrical components to avoid poor air circulation caused by tight installation. At the same time, air can enter the electrical control cabinet and between electrical components to promote air circulation between them, improve heat dissipation, and effectively ensure the performance stability and service life of electrical components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an external electrical control cabinet, comprising an electrical control cabinet body and a cabinet door hinged to the front end of the electrical control cabinet body, wherein the rear wall inside the electrical control cabinet body is provided with a heat dissipation mounting assembly, which facilitates the installation of electrical components inside the electrical control cabinet body and the air circulation and heat dissipation between electrical components.

[0006] The heat dissipation mounting assembly includes a hollow back plate fixed to the rear wall inside the electrical control cabinet, and the front side of the hollow back plate is provided with multiple mounting parts distributed vertically.

[0007] A fan is fixed at the rear end of the electrical control cabinet.

[0008] Preferably, the mounting component includes a hollow mounting plate, the front end of which is fixed with an electrical mounting rail. The electrical mounting rail is a standardized metal track used in the industrial electrical field to fix electrical components, and it has the characteristics of convenient installation, flexible layout, and easy maintenance. The electrical components required by the comet-type filtration system are fixed on the electrical mounting rail. The front end of the hollow mounting plate is provided with multiple through holes on the outside of the electrical mounting rail, and the rear ends of the hollow mounting plate are provided with ventilation openings on both sides. The through holes and ventilation openings are all connected to the interior of the hollow mounting plate.

[0009] Preferably, L-shaped plates are fixed to both sides of the front end of the hollow back panel, and a sliding groove is formed between the L-shaped plates and the front side of the hollow back panel. The hollow mounting plate is slidably disposed in the two sliding grooves on both sides. Threaded rods are fixed to the front ends of both sides of the hollow mounting plate. A sliding groove is opened at the front end of the L-shaped plate. The threaded rod passes through the sliding groove and is slidably connected to the sliding groove. Nuts are threaded onto the threaded rods and are disposed at the front end of the L-shaped plate for fixing the hollow mounting plate.

[0010] Preferably, air outlets are provided on both sides of the front end of the hollow back panel, and an opening is provided at the rear end of the hollow back panel. Both the air outlets and the opening are connected to the interior of the hollow back panel to facilitate air circulation inside the hollow back panel.

[0011] Preferably, the rear end of the electrical control cabinet is provided with an air inlet, which is located in front of the fan. The air inlet, the opening, the interior of the hollow back panel, the air outlet, the ventilation opening, the interior of the hollow mounting plate, and the through hole are connected in sequence to facilitate the fan to blow air and dissipate heat between the electrical components inside the electrical control cabinet and on the mounting parts.

[0012] Preferably, an air outlet is provided on one side of the electrical control cabinet, and an adjustable air outlet component is fixed on one side of the electrical control cabinet at the position of the air outlet; the adjustable air outlet component includes an air outlet channel fixed on one side of the electrical control cabinet, a rotating baffle is rotatably provided inside the air outlet channel, and a motor for driving the rotating baffle to rotate is fixed on the outer wall of the air outlet channel for adjusting the air volume of the cabinet.

[0013] Preferably, a pressure gauge is fixed at the front end of the cabinet door to monitor the air pressure inside the electrical control cabinet, so as to maintain a slight positive pressure inside the electrical control cabinet, that is, the air pressure inside the cabinet is slightly higher than the external ambient air pressure, usually with a pressure difference of 50-500 Pa.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model facilitates the adjustment of the distance between adjacent hollow mounting plates, so that electrical components of different sizes can be installed on the hollow mounting plates. It not only has a wide range of applications, but also avoids poor air circulation between electrical components due to tight installation. At the same time, the operation of the fan can drive external air into the electrical control cabinet and between electrical components, promote air circulation between electrical components, improve heat dissipation, and effectively ensure the performance stability and service life of electrical components.

[0016] 2. The size of the air outlet channel can be adjusted by rotating the baffle driven by the motor, thereby adjusting the air volume of the electrical control cabinet. In conjunction with the air pressure gauge, the air pressure inside the electrical control cabinet is monitored to maintain a slight positive pressure inside the cabinet. This ensures a continuous outward airflow inside the electrical control cabinet, preventing external dust and moisture from entering, and further ensuring the performance stability and service life of electrical components.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1-8 An external electrical control cabinet is shown, including an electrical control cabinet body 1 and a cabinet door 2 hinged to the front end of the electrical control cabinet body 1. A fan 4 is fixed to the rear end of the electrical control cabinet body 1. An air inlet 11 is opened at the rear end of the electrical control cabinet body 1 and is located in front of the fan 4. An air outlet is opened on one side of the electrical control cabinet body 1.

[0033] The rear wall inside the electrical control cabinet 1 is provided with a heat dissipation mounting assembly 3. The heat dissipation mounting assembly 3 includes a hollow back plate 31 fixed to the rear wall inside the electrical control cabinet 1. L-shaped plates 33 are fixed on both sides of the front end of the hollow back plate 31, and a sliding groove 34 is formed between the L-shaped plates 33 and the front side of the hollow back plate 31.

[0034] The hollow back panel 31 has multiple vertically distributed mounting components 32 on its front side. Each mounting component 32 includes a hollow mounting plate 321. An electrical mounting rail 322 is fixed to the front end of the hollow mounting plate 321, and electrical components are fixed on the electrical mounting rail 322. The two sides of the hollow mounting plate 321 are slidably disposed in two sliding grooves 34. Threaded rods 325 are fixed to the front ends of both sides of the hollow mounting plate 321. A sliding groove 327 is opened at the front end of the L-shaped plate 33. The threaded rod 325 passes through the sliding groove 327 and is slidably connected to the sliding groove 327. A nut 326 is threadedly connected to the threaded rod 325 and is disposed at the front end of the L-shaped plate 33.

[0035] In use, the electrical components required by the comet-type filtration system are fixed on the electrical mounting rails 322 of each set of hollow mounting plates 321. The hollow mounting plates 321 can slide up and down along the slide grooves 34 to adjust the distance between adjacent hollow mounting plates 321. After adjustment, tightening the nuts 326 on the threaded rods 325 of the hollow mounting plates 321 will fix the hollow mounting plates 321. This utility model facilitates the adjustment of the distance between the hollow mounting plates 321 so that electrical components of different sizes can be installed on the hollow mounting plates 321. It not only has a wide range of applications, but also avoids poor air circulation between components due to tight installation between electrical components.

[0036] Next, as Figures 4-7 As shown, air outlets 311 are provided on both sides of the front end of the hollow back panel 31, and an opening 312 is provided at the rear end of the hollow back panel 31. Both the air outlets 311 and the opening 312 are connected to the interior of the hollow back panel 31.

[0037] The hollow mounting plate 321 has multiple through holes 323 at its front end located outside the electrical installation rail 322. Ventilation openings 324 are provided on both sides of the rear end of the hollow mounting plate 321. The through holes 323 and ventilation openings 324 are connected to the interior of the hollow mounting plate 321. The air inlet 11, opening 312, interior of hollow back plate 31, air outlet 311, ventilation opening 324, interior of hollow mounting plate 321, and through holes 323 are connected sequentially.

[0038] When the electrical components inside the electrical control cabinet 1 are running, the fan 4 drives external air to enter the electrical control cabinet 1 through the air inlet 11, opening 312, hollow back panel 31, and air outlet 311 to dissipate heat from the electrical components inside the electrical control cabinet 1. The air is discharged through the air outlet on one side of the electrical control cabinet 1. At the same time, the air inside the hollow back panel 31 can also enter the hollow mounting plate 321 through the air outlet 311 and ventilation opening 324. The air then enters between the electrical components through the through holes 323, promoting air circulation between the electrical components, improving the heat dissipation effect, and effectively ensuring the performance stability and service life of the electrical components.

[0039] In addition, this utility model can install dustproof nets at the air inlet and outlet of the electrical control cabinet 1 to prevent dust from entering the electrical control cabinet 1;

[0040] On the other hand, such as Figure 1 , Figure 2 and Figure 8As shown, a pressure gauge 6 for monitoring the air pressure inside the electrical control cabinet 1 is fixed at the front end of the cabinet door 2. An adjustable air outlet component 5 is fixed at the air outlet on one side of the electrical control cabinet 1. The adjustable air outlet component 5 includes an air outlet channel 51 fixed on one side of the electrical control cabinet 1. A rotating baffle 52 is rotatably provided inside the air outlet channel 51, and a motor 53 for driving the rotating baffle 52 to rotate is fixed on the outer wall of the air outlet channel 51.

[0041] The size of the air outlet channel 51 can be adjusted by rotating the rotating baffle 52 driven by the motor 53, thereby adjusting the air volume of the electrical control cabinet 1. In conjunction with the pressure gauge 6, the air pressure inside the electrical control cabinet 1 is monitored to maintain a slight positive pressure inside the cabinet, that is, the air pressure inside the cabinet is slightly higher than the external ambient air pressure, usually with a pressure difference of 50-500Pa. The slight positive pressure environment inside the electrical control cabinet 1 has a continuous outward airflow, which has the function of preventing external dust and moisture from entering, further ensuring the performance stability and service life of electrical components.
