Description

Technical Field

[0001] The utility model relates to the technical field of electrical switch cabinets, and particularly relates to an electrical switch cabinet with a monitoring device. Background Art

[0002] In the field of electrical engineering applications, the importance of electrical switch cabinets is self-evident. However, due to the presence of a large number of electrical components inside, a large amount of heat is generated when these components work, causing the temperature inside the electrical switch cabinet to rise, which easily leads to the burning of internal electrical components. Although the heat inside the existing electrical switch cabinets can be discharged through a fan, the fan is also in an on state when the temperature inside the electrical switch cabinet is not high, wasting a lot of electrical energy, and the air outlet cannot be sealed, making it easy for dust and sundries to enter the inside of the electrical switch cabinet. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electrical switch cabinet with a monitoring device, which can stop the exhaust fan from working when the heat inside the switch cabinet is not high, reduce power consumption, and at the same time can seal the ventilation opening to prevent dust and sundries from entering the inside of the cabinet and affecting the normal operation of electrical components.

[0004] To solve the above technical problems, the utility model adopts the following solutions:

[0005] An electrical switch cabinet with a monitoring device includes a cabinet body. A ventilation opening is provided on the side wall of the cabinet body, and an exhaust fan for heat dissipation is provided at the ventilation opening. A first sealing plate and a second sealing plate located outside the cabinet body are movably connected to the side wall of the cabinet body. The first sealing plate and the second sealing plate can rotate relative to each other. A driving component for driving the first sealing plate and the second sealing plate to rotate relative to each other and realizing the sealing or opening of the ventilation opening is provided below the ventilation opening. The driving component is arranged on the side wall of the cabinet body and is located outside the cabinet body.

[0006] Due to the adoption of the above technical solution, a ventilation opening is provided on the side wall of the cabinet body to ensure the effective heat dissipation of electrical equipment during operation and prevent equipment failures or safety hazards caused by overheating. The exhaust fan is arranged at the ventilation opening to accelerate the air circulation inside and outside the cabinet by actively exhausting air, improving the heat dissipation efficiency. The first sealing plate and the second sealing plate can rotate relative to each other and cover the ventilation opening. When heat dissipation is not required inside the electrical switch cabinet, the exhaust fan can be stopped to save electrical energy, and then the two sealing plates are rotated to seal the ventilation opening, reducing the possibility of external dust and sundries entering the inside of the electrical switch cabinet and preventing the attachment of dust to the internal electrical components of the electrical switch cabinet and affecting normal operation. The driving component is installed on the side wall of the cabinet body and is located outside the cabinet body. Such a design facilitates external operation and maintenance, and the opening and closing of the ventilation opening can be realized without opening the cabinet door.

[0007] The driving component drives the first sealing plate and the second sealing plate to rotate relative to each other mechanically. When heat dissipation is required, the driving component opens the sealing plates to expose the ventilation opening; when sealing is required, the two sealing plates are closed to seal the ventilation opening, so that the inside of the cabinet is not connected to the outside, and pollutants such as dust are not easily introduced into the switch cabinet, ensuring the normal use of the electrical equipment in the switch cabinet and extending the service life of the device.

[0008] Optionally, both the first sealing plate and the second sealing plate are semi-circular. The upper ends of the first sealing plate and the second sealing plate are hinged to the outer wall of the cabinet, and the hinge points are located above the ventilation opening. The first sealing plate and the second sealing plate rotate relative to each other under the action of the driving component and form a circular sealing plate after closing. The area of the circular sealing plate is larger than the area of the ventilation opening.

[0009] Optionally, a first sealing gasket is adhesively bonded to the opposite surfaces of the first sealing plate and the second sealing plate.

[0010] Optionally, a second sealing gasket is adhesively bonded to the surfaces of the first sealing plate and the second sealing plate in contact with the outer wall of the cabinet, and the second sealing gasket is closely attached to the outer wall of the cabinet.

[0011] Optionally, a rain shield extending to the outside of the cabinet is provided at the top of the cabinet, and the driving component is located below the rain shield.

[0012] Optionally, the driving component includes a driving member and a transmission rod. The driving member is installed on the outer wall of the cabinet, the output end of the driving member faces upward, and two transmission rods are hinged to the output end. The ends of the two transmission rods away from the driving member are respectively hinged to the lower ends of the first sealing plate and the second sealing plate. The driving member drives the two transmission rods to rotate relative to each other and drives the first sealing plate and the second sealing plate to rotate relative to each other to open or close the ventilation opening.

[0013] Optionally, the driving member is a hydraulic cylinder, an electric cylinder or a pneumatic cylinder. The driving member is electrically connected to the PLC controller inside the cabinet, and a temperature sensor electrically connected to the PLC controller is also provided inside the cabinet.

[0014] Optionally, a filter screen is clamped in the ventilation opening.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the device has a simple structure and a reasonable design. By monitoring the temperature inside the electrical switch cabinet through a temperature control sensor, when the electrical switch cabinet does not need heat dissipation, the two sealing plates seal the ventilation opening, and its interior is not connected to the outside. Pollutants such as dust are not easily introduced into the switch cabinet, ensuring the normal use of the electrical equipment in the switch cabinet and extending the service life of the device;

[0017] 2. When the temperature inside the switch cabinet is too high, the driving member drives the two transmission rods to rotate relative to each other, and drives the first sealing plate and the second sealing plate to rotate relative to each other, so that the inside and outside of the electrical switch cabinet are communicated through the ventilation openings, and the exhaust fan works to dissipate heat from the inside of the switch cabinet, ensuring the normal operation of the components inside the switch cabinet and having a good heat dissipation effect.

[0025] Embodiment

[0026] An electrical switchgear cabinet with a monitoring device, comprising a cabinet body 1. A ventilation opening 2 is provided on the side wall of the cabinet body 1. An exhaust fan 3 for heat dissipation is provided at the ventilation opening 2. A first sealing plate 4 and a second sealing plate 5 located outside the cabinet body 1 are movably connected to the side wall of the cabinet body 1. The first sealing plate 4 and the second sealing plate 5 can rotate relative to each other. A driving assembly for driving the first sealing plate 4 and the second sealing plate 5 to rotate relative to each other and realizing the sealing or opening of the ventilation opening 2 is provided below the ventilation opening 2. The driving assembly is arranged on the side wall of the cabinet body 1 and is located outside the cabinet body 1.

[0027] In this embodiment, as Figure 1 shown, a ventilation opening 2 is provided on the side wall of the cabinet body 1 to ensure that the electrical equipment can dissipate heat effectively during operation, preventing equipment failures or safety hazards caused by overheating. The exhaust fan 3 is provided at the ventilation opening 2, and the air circulation inside and outside the cabinet body 1 is accelerated by the active exhaust method, improving the heat dissipation efficiency. The first sealing plate 4 and the second sealing plate 5 can rotate relative to each other and cover the ventilation opening 2. When heat dissipation is not required inside the electrical switchgear cabinet, the exhaust fan 3 can be stopped to save electric energy, and then the two sealing plates are rotated to seal the ventilation opening 2, reducing the possibility of external dust and debris entering the interior of the electrical switchgear cabinet and avoiding the influence of dust adhering to the electrical components inside the electrical switchgear cabinet on the normal operation. The driving assembly is installed on the side wall of the cabinet body 1 and is located outside the cabinet body 1. Such a design facilitates external operation and maintenance, and the opening and closing of the ventilation opening 2 can be realized without opening the cabinet door. The driving assembly drives the first sealing plate 4 and the second sealing plate 5 to rotate relative to each other mechanically. When heat dissipation is required, the driving assembly opens the sealing plates to expose the ventilation opening 2; when sealing is required, the two sealing plates are closed to seal the ventilation opening 2, and its interior is not connected to the outside, and dust and other pollutants are not easily introduced into the switchgear cabinet, ensuring the normal use of the electrical equipment inside the switchgear cabinet and extending the service life of the device.

[0028] Furthermore, both the first sealing plate 4 and the second sealing plate 5 are semi-circular in shape. The upper ends of the first sealing plate 4 and the second sealing plate 5 are hinged to the outer wall of the cabinet body 1, and the hinge points are located above the ventilation opening 2. The first sealing plate 4 and the second sealing plate 5 rotate relative to each other under the action of the driving assembly and form a circular sealing plate 11 after closing. The area of the circular sealing plate 11 is larger than the area of the ventilation opening 2.

[0029] Specifically, as Figure 1 shown, the upper ends of these two semi-circular sealing plates (the first sealing plate 4 and the second sealing plate 5) are connected to the outer wall of the cabinet body 1 by means of hinges, and the position of the hinge points is deliberately selected above the ventilation opening 2. Such a layout enables the sealing plates to rotate around the hinge points, thereby changing their positions relative to the ventilation opening 2. When the temperature inside the electrical switchgear cabinet is relatively low and heat dissipation is not required, the exhaust fan 3 can be stopped. At this time, it is necessary to close the ventilation opening 2. Under the action of a driving assembly, as Figure 3As shown, the two sealing plates will rotate relative to each other and gradually approach until they completely overlap, forming a complete circular sealing plate 11. Since each sealing plate is semi-circular in shape, the circular sealing plate 11 formed after they are closed must be larger in area than the original ventilation opening 2, thus ensuring that the ventilation opening 2 is completely and effectively sealed. This design is not only compact in structure and simple to operate, but also has a good sealing effect, and can effectively prevent dust, moisture or other unwanted substances from entering the cabinet 1 through the ventilation opening 2, protecting the equipment or items inside the cabinet 1 from damage. At the same time, when ventilation is required, simply operate the driving component in the reverse direction to separate the two sealing plates and move them away from the ventilation opening 2, then the ventilation opening 2 can be opened.

[0030] Furthermore, a first sealing gasket 8 is adhesively bonded to the opposite surfaces of the first sealing plate 4 and the second sealing plate 5.

[0031] Specifically, as Figure 1 and Figure 2 shown, the first sealing gasket 8 is a material with good elasticity and sealing performance. It can effectively fill the tiny gaps between the two sealing plates, preventing air, dust, moisture or other impurities from infiltrating or leaking through these gaps. When the two sealing plates are closed, the first sealing gasket 8 will be compressed, further enhancing the sealing effect. This design not only improves the sealing performance when the ventilation opening 2 is closed, but also can, to a certain extent, reduce the problem of sealing failure caused by factors such as vibration or temperature change. At the same time, the use of the first sealing gasket 8 also extends the service life of the sealing plates because it can reduce the direct friction and wear between the two sealing plates. In summary, the addition of the first sealing gasket 8 is an important measure to improve the sealing performance of the first sealing plate 4 and the second sealing plate 5, ensuring the effective sealing of the ventilation opening 2 in the closed state.

[0032] Furthermore, a second sealing gasket 9 is adhesively bonded to the surfaces of the first sealing plate 4 and the second sealing plate 5 that are in contact with the outer wall of the cabinet 1, and the second sealing gasket 9 is in close contact with the outer wall of the cabinet 1.

[0033] Specifically, the second sealing gasket 9 is also a material with good elasticity and sealing performance. It is pasted on the surfaces of the first sealing plate 4 and the second sealing plate 5 that are in contact with the outer wall of the cabinet body 1, or can be fixed by screws. When the sealing plate is in the closed state, the second sealing gasket 9 will closely fit with the outer wall of the cabinet body 1, forming an additional sealing barrier. This close fit not only prevents the penetration of external substances such as air, dust, and moisture, but also reduces the noise generated by air flow. In addition, the second sealing gasket 9 can also buffer the collision between the sealing plate and the outer wall of the cabinet body 1 to a certain extent, protecting both from damage, which is particularly important for scenarios where the ventilation opening 2 needs to be frequently opened and closed, as it can extend the service life of the sealing plate and the cabinet body 1. In summary, the addition of the second sealing gasket 9 further enhances the sealing performance between the first sealing plate 4 and the second sealing plate 5 and the outer wall of the cabinet body 1, ensures the complete sealing of the ventilation opening 2 in the closed state, and improves the durability and reliability of the entire system.

[0034] Furthermore, a rain shield 10 extending to the outside of the cabinet body 1 is provided at the top of the cabinet body 1, and the driving assembly is located below the rain shield 10.

[0035] Specifically, as Figure 2 shown, the rain shield 10 is usually designed with a certain inclination angle to quickly direct the rainwater falling on it away from the cabinet body 1. In addition, the material and surface treatment of the rain shield 10 also take into account requirements such as waterproof, corrosion-resistant, and easy to clean to ensure its long-term effective operation. At the same time, the description mentions that the driving assembly is located below the rain shield 10, which means that the mechanical device that drives the first sealing plate 4 and the second sealing plate 5 to rotate relative to each other and close or separate is installed in a relatively dry and protected environment. This layout helps to reduce the failures and damages of the driving assembly caused by moisture, corrosion, or pollution, thereby improving the reliability and service life of the entire ventilation opening 2 control system. In summary, the design of the rain shield 10 not only enhances the waterproof performance of the cabinet body 1, but also provides a good working environment for the driving assembly, further improving the overall performance and stability of the ventilation opening 2 control system.

[0036] Furthermore, the driving assembly includes a driving member 7 and a transmission rod 6. The driving member 7 is installed on the outer wall of the cabinet body 1, the output end of the driving member 7 faces upward, and two transmission rods 6 are hinged to the output end. The two ends of the two transmission rods 6 away from the driving member 7 are respectively hinged to the lower ends of the first sealing plate 4 and the second sealing plate 5. The driving member 7 drives the two transmission rods 6 to rotate relative to each other and drives the first sealing plate 4 and the second sealing plate 5 to rotate relative to each other to open or close the ventilation opening 2.

[0037] Specifically, the driving member 7 is installed on the outer wall of the cabinet body 1, and its output end is arranged upward. Such a layout enables the driving member 7 to directly act on the transmission rod 6 and transmit power to the two sealing plates through the transmission rod 6. On the output end of the driving member 7, two transmission rods 6 are hinged. These two transmission rods 6 are respectively hinged to the lower ends of the first sealing plate 4 and the second sealing plate 5, forming a lever system. When the driving member 7 starts to work, it drives the output end to move, thereby driving the two transmission rods 6 to rotate relative to each other. Since the transmission rods 6 are hinged to the two sealing plates, this relative rotation will be converted into the rotational movement of the sealing plates. As the transmission rods 6 rotate relative to each other, the first sealing plate 4 and the second sealing plate 5 will also rotate relative to each other accordingly. When they gradually approach each other, the ventilation opening 2 will be gradually closed; while when they gradually separate, the ventilation opening 2 will be gradually opened. In this way, the driving assembly can achieve precise control of the opening and closing of the ventilation opening 2. To sum up, the driving assembly transmits power to the first sealing plate 4 and the second sealing plate 5 through the coordinated work of the driving member 7 and the transmission rod 6, and drives them to rotate relative to each other to achieve the opening or closing of the ventilation opening 2. This design has a simple structure, convenient operation, and can effectively control the opening and closing state of the ventilation opening 2.

[0038] Furthermore, the driving member 7 is a hydraulic cylinder, an electric cylinder or a pneumatic cylinder. The driving member 7 is electrically connected to the PLC controller inside the cabinet body 1. A temperature sensor electrically connected to the PLC controller is also provided inside the cabinet body 1.

[0039] Specifically, the driving member 7 is electrically connected to a PLC (Programmable Logic Controller) controller inside the cabinet 1. The PLC controller is a computer specifically used for industrial automation control. It can control the operation of various devices according to preset programs and input signals. In this system, the PLC controller receives signals from the temperature sensor and controls the working state of the driving member 7 based on these signals and preset logic rules. The temperature sensor is also installed inside the cabinet 1 and is electrically connected to the PLC controller. The main function of the temperature sensor is to monitor the temperature inside the cabinet 1 in real time and convert this temperature information into electrical signals and send them to the PLC controller. The PLC controller determines whether to adjust the opening degree of the ventilation opening 2 based on the received temperature signals to maintain the temperature inside the cabinet 1 within a suitable range. For example, when the temperature inside the cabinet 1 exceeds the preset upper limit, the PLC controller can send a signal to the driving member 7, and the driving member 7 then works. The first sealing plate 4 and the second sealing plate 5 are gradually separated by the transmission rod 6, increasing the opening degree of the ventilation opening 2. The exhaust fan 3 is turned on and discharges the heat inside the cabinet 1. On the contrary, when the temperature inside the cabinet 1 is lower than the preset lower limit, the PLC controller can send a signal to make the driving member 7 drive the sealing plates to gradually close, reducing the opening degree of the ventilation opening 2 and stopping the exhaust fan 3 from working to keep the temperature inside the cabinet 1 stable. In summary, by using a hydraulic cylinder, an electric cylinder or a pneumatic cylinder as the driving member 7 and cooperating with the PLC controller and the temperature sensor, this ventilation opening 2 control system can achieve precise control and adjustment of the temperature inside the cabinet 1.

[0040] Furthermore, a filter screen is snap-fitted inside the ventilation opening 2. Specifically, the filter screen (not marked in the figure) is usually made of a fine mesh material. These materials have good air permeability and filtering performance. They are designed to fit the size of the ventilation opening 2 and are firmly installed inside the ventilation opening 2 by snap-fitting, screw fixing or other means. In this way, when air enters the cabinet 1 through the ventilation opening 2, the filter screen can effectively block impurities and keep the inside of the cabinet 1 clean and hygienic. In addition, the filter screen can be replaced or cleaned as needed. As the usage time increases, a certain amount of dust and impurities will accumulate on the filter screen, which will reduce its filtering effect and increase the resistance of air flow. Therefore, regularly replacing or cleaning the filter screen is an important measure to keep the ventilation opening 2 unobstructed and maintain the filtering effect.

[0041] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present invention still fall within the protection scope of the technical solution of the present invention.
