Description

Technical Field

[0001] The present invention relates to the field of electrical technology, and more particularly, to an electric control cabinet with an automatic warning function. Background Art

[0002] Under the background of the rapid development of the smart grid, the operating efficiency and energy utilization efficiency of the power system have become key considerations. The smart grid integrates advanced communication, control, and information technologies to achieve intelligent management of all links of power production, transmission, distribution, and consumption, aiming to improve the reliability, economy, and environmental friendliness of the power grid. As an indispensable part of the smart grid, the electric control cabinet undertakes important tasks of power control and protection, and its stability and efficient operation are crucial for the safe and economic operation of the entire power system.

[0003] However, traditional electric control cabinets face many challenges in design and application, especially in heat dissipation and energy efficiency management. First of all, a large number of electrical components are integrated inside the electric control cabinet, and these components will generate a large amount of heat during long-term operation. Effective heat dissipation measures are the key to ensuring the normal operation of the electric control cabinet. The traditional heat dissipation method of the electric control cabinet mostly uses heat dissipation holes on the side to dissipate heat through natural convection, but this method has obvious limitations. The heat dissipation path of the side heat dissipation holes usually has bends, resulting in poor discharge of hot air and low heat dissipation efficiency. This not only affects the working stability of the components inside the electric control cabinet but also increases energy consumption. Secondly, when there are other devices or obstacles around the electric control cabinet, the heat dissipation holes are easily blocked, further affecting the heat dissipation effect.

[0004] In response to the above problems, some electric control cabinets adopt a top heat dissipation method, and enhance the heat dissipation effect by setting heat dissipation devices such as heat dissipation fans on the top of the electric control cabinet. However, although this top heat dissipation method solves the problem of low heat dissipation efficiency, since the heat dissipation ports are directly exposed to the air, dust is more likely to enter the inside of the electric control cabinet, causing damage to electrical components. Especially in an environment with a lot of dust, the cleaning and maintenance costs inside the electric control cabinet increase significantly.

[0005] Moreover, the electric control cabinet also faces challenges in temperature monitoring and warning during operation. When the temperature inside the electric control cabinet is too high, if it cannot be detected and corresponding measures are not taken in time, it may cause overheating and damage of electrical components, and even lead to safety accidents such as fires.

[0006] To solve the above problems, an electric control cabinet with an automatic warning function is proposed. Summary of the Invention

Slide rails are arranged on both sides of the installation groove at the top of the cabinet body; The dust cleaning component includes an electric telescopic rod arranged on one side of the top of the cabinet body, a slider slidably installed on the slide rail and arranged at the telescopic end of the electric telescopic rod, and a dust cleaning plate arranged on one side of the slider and above the cooling component.

[0010] The present invention is further arranged such that support bars are arranged at the upper end of the inner wall of the cabinet body, and there are two groups of support bars, respectively located on both sides of the installation groove; The cooling component includes a dust shielding member rotatably installed on the support bars and correspondingly closing the installation groove, an opening and closing driving member engaged with the dust shielding member on one side of the support bars, and a driving lever rotatably installed on the slide rail for pushing the opening and closing driving member.

[0011] The present invention is further arranged such that the cooling component further includes a grille plate fixedly installed at the bottom end of the support bars, and a cooling fan fixedly installed at the bottom end of the grille plate.

[0012] The present invention is further arranged such that a movable groove is opened at one end of the slide rail away from the electric telescopic rod, and the movable groove is movably matched with the driving lever; One end of the driving lever penetrates through the movable groove and extends above the slide rail.

[0013] The present invention is further configured such that the dust shielding member includes dust shielding blades corresponding to and closing the mounting grooves, and further includes rotating shafts provided at both ends of the dust shielding blades, and gears provided at one ends of the rotating shafts away from the dust shielding blades; Pressing portions and receiving portions are respectively provided at both ends of the dust shielding blades, and the pressing portions and the receiving portions are correspondingly matched.

[0014] The present invention is further configured such that the opening and closing driving member includes a guide rod provided on one side of the support bar, a driving rod movably inserted into one end of the guide rod, a rack provided on the driving rod and meshing with the gear, and a return spring provided in the inner cavity of the driving rod; A directional groove is formed at one end of the side wall of the support bar away from the guide rod, a directional rod is provided at one end of the driving rod away from the guide rod, and the directional rod and the directional groove are slidably installed.

[0015] The present invention is further configured such that the linkage assembly includes a rotating rod rotatably installed on the side of the driving rod away from the support bar, and a connecting rod provided at one end of the rotating rod away from the driving rod, and one end of the connecting rod away from the rotating rod is rotatably connected to a connecting ear on the closing plate.

The high-temperature warning and cooling mechanism provided at the top of the cabinet includes a cooling component and an ash cleaning component. During daily heat dissipation, the cooling component is closed, avoiding dust directly entering the cabinet from the top of the cabinet. At the same time, when it is necessary to open the cooling component for rapid cooling at high temperatures, the ash cleaning component can clean the dust accumulated on the cooling component, avoiding the accumulated dust entering the cabinet when the cooling component is opened. In summary, the present invention realizes automatically switching to the top heat dissipation mode when the temperature in the cabinet is too high, and at the same time cleaning the accumulated ash at the top, ensuring the heat dissipation efficiency and effectively preventing dust from entering the interior of the electric control cabinet, improving the heat dissipation performance of the electric control cabinet and the service life of electrical components.

[0019] 2.

[0020] 3. By integrating a temperature sensor and a control panel, the present invention realizes real-time monitoring and early warning of the temperature inside the electric control cabinet. When the temperature exceeds the set threshold, the cooling component and the dust cleaning component are automatically started, and different colored lights are emitted through the warning light to help users promptly discover and handle the overheating problem of the electric control cabinet, improving the safety and reliability of the electric control cabinet.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0032] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0033] For examples, see Figure 1 - Figure 8 , an electric control cabinet with automatic warning function, comprising a cabinet body 1, and heat dissipation holes 101 are opened on the upper sections of both sides of the cabinet body 1, a high temperature warning cooling mechanism 2 is arranged on the top of the cabinet body 1, and the heat dissipation holes 101 and the high temperature warning cooling mechanism 2 are not opened at the same time; The high temperature warning cooling mechanism 2 includes a cooling component 3 disposed at the top of the cabinet 1, and a dust cleaning component 4 disposed above the cooling component 3 for cleaning dust accumulation; A closing plate 5 corresponding to and closing the heat dissipation hole 101 is provided at the upper end of the inner wall of the cabinet 1, and a linkage component 6 rotatably connected to the cooling component 3 is provided on the closing plate 5; A temperature sensor is arranged inside the cabinet 1 , and a control panel 102 is arranged on the cabinet door of the cabinet 1 . The control panel 102 is electrically connected to the temperature sensor, the cooling component 3 and the dust cleaning component 4 .

[0034] The heat dissipation holes 101 are equally spaced strip-shaped openings for daily equipment heat dissipation. When in daily use, the closing plate 5 and the heat dissipation holes 101 are misaligned, making the heat dissipation holes 101 in an open state, while the temperature reduction component 3 is in a closed state. The heat generated inside the cabinet is discharged outward through the heat dissipation holes 101. When the temperature is normal, natural convection heat dissipation is only carried out through the side heat dissipation holes 101, reducing energy consumption and noise.

[0035] The temperature sensor is used to detect the temperature inside the cabinet body 1. Considering factors such as accuracy, installation method, environmental adaptability, and cost, a suitable temperature sensor is selected. It is electrically connected to the control panel 102 and can transmit the temperature data monitored inside the cabinet to the control panel 102 for analysis.

[0036] First, set a high-temperature threshold through the control panel 102. When the temperature value monitored by the temperature sensor is greater than the set high-temperature threshold, the control panel 102 activates the dust cleaning component 4 and the temperature reduction component 3. During the dust cleaning movement of the dust cleaning component 4, the closed temperature reduction component 3 will be opened, enabling heat to be discharged from the top of the cabinet body 1. At the same time, when the closed temperature reduction component 3 is opened, the closing plate 5 is driven to move upward through the linkage component 6, so that the closing plate 5 and the heat dissipation holes 101 are aligned to achieve sealing. That is, when the hot air inside the cabinet exceeds the threshold temperature, the side heat dissipation holes 101 are closed, and automatically switched to the top temperature reduction component 3 for heat dissipation, making the hot air discharge path change from a bend to a vertical direction. According to the principle of hot air rising, the heat inside the cabinet can be quickly discharged.

[0037] Its design specifically aims at the fact that the heat dissipation openings of the current electrical control cabinet are located on the side, which will lead to poor heat dissipation due to the bending of the heat dissipation path and the occlusion of the layout of surrounding equipment, and the heat dissipation openings of the current electrical control cabinet are located on the top, making it easy for dust in the air to enter and accumulate inside the cabinet under the action of gravity. The accumulation of dust will affect the heat dissipation of electrical components, thus affecting the service life of the electrical components inside the electrical control cabinet.

[0038] In summary, during daily use, natural heat dissipation by air convection is carried out through the side heat dissipation holes 101, and the temperature reduction component 3 closed at the top of the cabinet body 1 also prevents dust from entering and accumulating inside the cabinet under the action of gravity. When the temperature inside the cabinet exceeds the threshold, the control panel 102 activates the dust cleaning component 4 and the temperature reduction component 3. The dust cleaning component 4 first cleans the dust at the top of the temperature reduction component 3, and then through the action of cleaning the dust, pushes the opening switch of the temperature reduction component 3, so that the opening of the temperature reduction component 3 can carry out top heat dissipation. It should be noted that the opening switch of the temperature reduction component 3 is carried out after the dust cleaning component 4 completes the dust cleaning operation, so that when the opening of the temperature reduction component 3 is opened, the dust accumulated on the top will not fall into the cabinet.

[0039] An installation groove is provided at the top of the cabinet body 1, and the cooling component 3 is correspondingly installed in the installation groove. Slide rails 103 are provided on both sides of the installation groove at the top of the cabinet body 1. The dust cleaning component 4 includes an electric telescopic rod 401 provided on one side of the top of the cabinet body 1, a slider 402 provided at the telescopic end of the electric telescopic rod 401 and slidably installed on the slide rail 103, and a dust cleaning plate 403 provided on one side of the slider 402 and above the cooling component 3.

[0040] The installation groove penetrates through the top of the cabinet body 1. After the cooling component 3 is opened, the heat inside the cabinet body 1 can be discharged. When the cooling component 3 is in the closed state, its top is flush with the top of the cabinet body 1, so that when the dust cleaning component 4 moves, it can fit the closed top of the cooling component 3, thereby cleaning the accumulated dust.

[0041] Among them, when the dust cleaning component 4 moves to clean the dust, the electric telescopic rod 401 extends. Through the sliding of the slider 402 on the slide rail 103, the dust cleaning plate 403 is driven to move from one side of the cooling component 3 to the other side, thereby cleaning the dust on the cooling component 3 to the side, avoiding dust from falling into the interior of the cabinet body 1 after the cooling component 3 is opened, and further affecting the heat dissipation of the electrical components.

[0042] Among them, the slide rail 103 and the cabinet body 1 can be integrally formed by stamping or by welding. The inside of the slide rail 103 is a cavity, and the cross section of the slide rail 103 is T-shaped. The slider 402 is slidably installed in adaptation to the slide rail 103, so that the T-shape of the slide rail 103 plays a role in preventing detachment and stable sliding.

[0043] Furthermore, two groups of electric telescopic rods 401 are provided, corresponding to the two slide rails 103 respectively. The electric telescopic rod 401 is a multi-stage telescopic rod, which can meet the requirement that in its contracted state, the dust cleaning plate 403 can be located on one side of the cooling component 3, and after extension, it can drive the dust cleaning plate 403 to move to the other side of the cooling component 3, so as to comprehensively clean the dust on the opening and closing cooling component 3.

[0044] Specifically, when the temperature inside the cabinet body 1 exceeds the set high temperature threshold, the control panel 102 starts the electric telescopic rod 401, so that the electric telescopic rod 401 extends, thereby pushing the slider 402 to move on the slide rail 103. The movement of the slider 402 drives the movement of the dust cleaning plate 403. Through the movement and scraping of the dust cleaning plate 403, the dust on the cooling component 3 is cleaned from one side to the other side, thereby avoiding dust from falling into the interior of the cabinet body 1 after the cooling component 3 is opened.

[0045] Support bars 104 are provided at the top of the inner wall of the cabinet body 1, and two groups of support bars 104 are provided, respectively located on both sides of the installation groove. The temperature reduction assembly 3 includes a dust shielding member 7 rotatably mounted on the support bar 104 and corresponding to the closed mounting groove, and further includes an opening and closing driving member 8 disposed on one side of the support bar 104 and meshing with the dust shielding member 7, and a driving lever 301 rotatably mounted on the slide rail 103 for pushing the opening and closing driving member 8.

[0046] The temperature reduction assembly 3 further includes a grid plate 302 fixedly mounted at the bottom end of the support bar 104, and a cooling fan 303 fixedly mounted at the bottom end of the grid plate 302.

[0047] During daily use, the dust shielding member 7 is closed. When the dust shielding member 7 is closed, it is flush with the top end of the cabinet body 1, which is convenient for the fitting and cleaning of the dust cleaning plate 403. When the temperature inside the cabinet exceeds the high temperature threshold, the control panel 102 drives the slider 402 to drive the dust cleaning plate 403 to clean the dust through the electric telescopic rod 401. When the dust cleaning plate 403 moves from one side of the dust shielding member 7 to the other side, as the electric telescopic rod 401 continues to extend, the slider 402 pushes the driving lever 301 to rotate. Through the rotation of the other end of the driving lever 301, the opening and closing driving member 8 moves in the direction of the electric telescopic rod 401. When the opening and closing driving member 8 moves, through meshing with the dust shielding member 7, the dust shielding member 7 rotates and opens. And when the opening and closing driving member 8 moves, the closing plate 5 is driven to move upward through the linkage assembly 6, thereby realizing the closing of the heat dissipation holes 101, so that the heat inside the cabinet can only rise vertically and be discharged from the opening of the rotatably opened dust shielding member 7. Through the principle of hot air rising, the heat inside the cabinet can be quickly discharged, and the cooling fan 303 is started through the control panel 102, so that the temperature inside the cabinet can be quickly reduced, thereby protecting the safety of the electric control cabinet.

[0048] An activity groove 105 is formed at one end of the slide rail 103 away from the electric telescopic rod 401, and the activity groove 105 is movably matched with the driving lever 301; One end of the driving lever 301 penetrates through the activity groove 105 and extends above the slide rail 103.

[0049] The driving lever 301 is rotatably mounted in the cavity of the slide rail 103, and one end of it extending above the slide rail 103 enables the slider 402 to be better pushed when sliding on the slide rail 103.

[0050] The dust shielding member 7 includes a dust shielding blade 701 corresponding to the closed mounting groove, and further includes rotating shafts 702 disposed at both ends of the dust shielding blade 701, and gears 703 disposed at one ends of the rotating shafts 702 away from the dust shielding blade 701; Pressing portions 704 and receiving portions 705 are respectively disposed at both ends of the dust shielding blade 701, and the pressing portions 704 and the receiving portions 705 are correspondingly matched.

[0051] A number of sets of ash shielding plates 701 are arranged in a linear array, and the ash shielding member 7 that encloses the installation groove is formed by a number of sets of ash shielding plates 701. Among the number of sets of ash shielding plates 701 in the linear array, one of the ash shielding plates 701 at both ends has only a pressing portion 704, and the other has only a receiving portion 705. The ash shielding plates 701 located in the middle section are provided with both a pressing portion 704 and a receiving portion 705, so that the pressing portion 704 of adjacent ash shielding plates 701 can match the receiving portion 705. As a result, after the ash shielding member 7 is closed, it has a good sealing and ash shielding effect, specifically as Figure 7 shown

[0052] The opening and closing driving member 8 includes a guide rod 801 arranged on one side of the support bar 104, a driving rod 802 movably inserted into one end of the guide rod 801, a rack 803 arranged on the driving rod 802 and meshing with the gear 703, and a return spring 804 arranged in the inner cavity of the driving rod 802; One end of the side wall of the support bar 104 away from the guide rod 801 is provided with an orientation groove 106. One end of the driving rod 802 away from the guide rod 801 is provided with an orientation rod 805, and the orientation rod 805 and the orientation groove 106 are slidably installed.

[0053] When the temperature inside the cabinet does not exceed the high temperature threshold, under the action of the return spring 804, the driving rod 802 is pushed to move towards the driving lever 301, so that the guide rod 801 and the driving rod 802 are at the maximum length, the ash shielding member 7 is in the closed state, and the driving lever 301 is in the state as Figure 6 shown. When the temperature inside the cabinet exceeds the high temperature threshold, the electric telescopic rod 401 pushes the slider 402 to drive the ash cleaning plate 403 to move to remove the dust on the ash shielding member 7, and at the same time pushes the driving lever 301 to rotate. The rotation of the driving lever 301 pushes the driving rod 802 to move towards the guide rod 801 at the other end, compressing the return spring 804. The movement of the driving rod 802 drives the rack 803 to move, thereby driving the meshing gear 703 to rotate. As a result, the multiple sets of ash shielding plates 701 in the linear array that are closed rotate 90 degrees to be vertical, and the distance between adjacent ash shielding plates 701 forms a heat dissipation port. Under the principle of hot air rising and the action of the heat dissipation fan 303, the heat inside the cabinet is quickly discharged.

[0054] The linkage assembly 6 includes a rotating rod 601 rotatably installed on the side of the driving rod 802 away from the support bar 104, and a connecting rod 602 arranged at one end of the rotating rod 601 away from the driving rod 802. One end of the connecting rod 602 away from the rotating rod 601 is rotatably connected to the connecting ear on the closing plate 5.

[0055] Limit strips 107 are provided on both sides of the inner wall of the cabinet body 1. Limit grooves 501 are opened at both ends of one side of the closing plate 5, and the limit grooves 501 and the limit strips 107 are slidably installed; An air inlet 108 is provided at the bottom of the cabinet 1 .

[0056] When the driving rod 802 is pushed by the driving lever 301, it drives the rotating rod 601 to move, while the closing plate 5 cannot move laterally along the direction of movement of the driving rod 802. Therefore, under the action of the connecting rod 602, when the driving rod 802 moves, the rotating rod 601 rotates, thereby causing the connecting rod 602 to rotate, thereby driving the closing plate 5 to move upward, so that the closing plate 5 blocks the heat dissipation hole 101.

[0057] In summary, after the temperature inside the cabinet exceeds the set high temperature threshold, the dust on the dust shield 7 will be cleaned first, and the dust shield 7 on the top of the cabinet 1 will be opened, so that the heat dissipation port opened by the dust shield 7 on the top of the cabinet 1 and the bottom air inlet 108 form a vertical air duct, thereby reducing the bending path of hot air and improving the heat dissipation efficiency. The dust shield 7 is opened while the conventional heat dissipation holes 101 on both sides of the cabinet 1 are closed. The closing of the side heat dissipation holes 101 can avoid airflow turbulence and ensure the airtightness of the vertical air duct, thereby improving the heat dissipation effect of the cooling fan 303.

[0058] A dust box 9 is provided on one side of the top of the cabinet 1 away from the electric telescopic rod 401, and a warning light 10 is provided on one side of the top of the cabinet 1. The top of the dust box 9 is flush with the top of the cabinet 1, and is used to receive the dust cleaned by the dust cleaning plate 403. The dust box 9 is detachable, which is convenient for regular cleaning of the dust inside the dust box 9. The warning light 10 is electrically connected to the control panel 102. The warning light 10 can emit lights of different colors according to the temperature value in the cabinet. At normal temperature, it emits green light, when it is close to the set high temperature threshold, it emits yellow light, and when it exceeds the set threshold, it emits red light.

[0059] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention.
