An electromechanical control cabinet

Abstract

This utility model discloses an electromechanical control cabinet, belonging to the field of electromechanical control cabinets, and aims to solve the problem in the prior art where, when strong winds carry raindrops that impact louvers, the raindrops do not fall vertically but instead strike the blade surface directly at a high horizontal speed. Because the blade surface is flat or simply inclined, the high-speed impact of the raindrops causes violent splashing, forming a large number of tiny water droplets. These droplets can enter the cabinet through gaps between the blades, gaps between the louvers and the cabinet body, or be carried by airflow. Especially when the wind force reaches level 6 or above, the airflow disturbance exacerbates the spread of the water droplets, leading to the intrusion of small droplets into the electromechanical control cabinet and causing problems. The cabinet includes an electromechanical control cabinet body, with a cabinet door hinged to the front end. Ventilation mechanisms are provided at the lower left and right ends of the cabinet body, and the ventilation mechanisms include rectangular frames connected to the lower left and right ends of the cabinet body.

Description

Technical Field

[0001] This utility model belongs to the field of electromechanical control cabinets, and specifically relates to an electromechanical control cabinet. Background Technology

[0002] As a core control unit in industrial automation, municipal engineering, and new energy fields, the stable operation of electromechanical control cabinets directly affects the safety and reliability of the entire system. To meet the needs of outdoor or semi-outdoor environments, control cabinets typically require excellent dustproof and rainproof performance to prevent external pollutants or rainwater intrusion that could lead to short circuits, corrosion, and other malfunctions in internal electrical components. Currently, most electromechanical control cabinets on the market achieve a balance between ventilation and environmental protection by installing dustproof and rainproof louvers on the side walls or top of the cabinet. These louvers generally use an inclined blade structure, with the blades forming a tortuous channel. Theoretically, this allows rainwater to slide down the blades under gravity and prevents external dust from entering through the staggered blade arrangement. However, in practical applications, especially in severe weather conditions with wind and rain, this structure still poses a significant risk of rainwater intrusion.

[0003] When strong winds carry raindrops that impact the louvers, the raindrops do not fall vertically but instead strike the blade surface directly at a high horizontal speed. Because the blade surface is flat or simply inclined, the high-speed impact of the raindrops causes violent splashing, forming a large number of tiny water droplets. These droplets can enter the cabinet through gaps between the blades, gaps between the louvers and the cabinet, or be carried by the airflow. Especially when the wind force reaches level 6 or above, the airflow disturbance exacerbates the spread of the water droplets, causing small droplets to intrude into the electromechanical control cabinet and cause problems. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an electromechanical control cabinet that solves the problem that when strong winds carry raindrops that impact the louvers, the raindrops do not fall vertically but instead strike the blade surface directly at a high horizontal velocity. Because the blade surface is flat or simply inclined, the high-speed impact of the raindrops causes violent splashing, forming numerous tiny water droplets. These droplets can enter the cabinet through gaps between the blades, gaps between the louvers and the cabinet body, or be carried by the airflow. Especially when the wind force reaches level 6 or higher, the airflow disturbance exacerbates the spread of the water droplets, leading to the intrusion of small droplets into the electromechanical control cabinet and causing problems.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides an electromechanical control cabinet, comprising a cabinet body, a cabinet door hinged to the front end of the cabinet body, ventilation mechanisms located at the lower left and right ends of the cabinet body, and the ventilation mechanisms including rectangular frames connected to the lower left and right ends of the cabinet body, a dustproof net installed on the left inner side of the rectangular frame, inclined louver blades fixedly connected at equal intervals on the right inner side of the rectangular frame, a rotating shaft connected to the right end of the rectangular frame, a gear fixedly connected to the outer front end of the rotating shaft, a baffle fixedly connected to the outer part of the rotating shaft located inside the rectangular frame, a mounting plate fixedly connected to the right front side of the rectangular frame, a miniature electric push rod mounted on the upper end of the mounting plate, a protective cover fixedly connected to the upper side of the mounting plate at the outer end of the miniature electric push rod, a gear fixedly connected to the lower end of the output shaft of the miniature electric push rod, a collection unit located on the lower side of the rectangular frame, and a disassembly unit located at the outer end of the rectangular frame.

[0008] Furthermore, the collection unit includes a collection box disposed below the rectangular frame, with sliding rods fixedly connected to the upper left and right sides of the collection box, and L-shaped rods fixedly connected symmetrically to the lower right end of the rectangular frame, with a stop block fixedly connected to the rear side of the L-shaped rod.

[0009] Furthermore, the disassembly and assembly unit includes threaded rods fixedly connected to the lower front and rear ends of the left and right sides of the electromechanical control cabinet, with nuts threadedly connected to the outer side of the threaded rods, and an installation frame fixedly connected to the outer side of the rectangular frame.

[0010] Furthermore, the front ends of the rectangular frame are provided with rotating holes at the upper left side of the dustproof net, the outer sides of the front and rear ends of the rotating shaft are rotatably connected to the inner sides of the rotating holes, and the front and rear sides of the baffle are slidably connected to the front and rear ends of the inner side of the rectangular frame.

[0011] Furthermore, the outer end of the rack meshes with the outer end of the gear.

[0012] Furthermore, the outer side of the sliding rod is slidably connected to the inner side of the L-shaped rod.

[0013] Furthermore, the sliding rod is an iron rod, the stop block is a magnetic rod, the rear side of the sliding rod abuts against the front side of the stop block, and the lower end of the rectangular frame is provided with a through-hole at the top and bottom of the collection box.

[0014] Furthermore, the electromechanical control cabinet has through slots at the lower left and right ends, the outer side of the rectangular frame is slidably connected to the inner side of the through slots, and the mounting frame has through mounting holes at the middle of the front and rear ends, the outer side of the threaded rod is slidably connected to the inner side of the mounting holes, and the left and right sides of the mounting frame abut against the electromechanical control cabinet and the side of the threaded rod adjacent to it.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the installation of a ventilation mechanism, allows for smoother airflow between the louvers of the control cabinet during dry weather. In dry weather, the miniature electric actuator drives the rack upwards, causing the shaft to rotate clockwise and rotate the baffle horizontally towards the inside of the cabinet. This facilitates airflow between the louvers. During rainy weather, the miniature electric actuator drives the rack downwards, rotating the baffle so that the louvers are perpendicular to its lower edge. This prevents water droplets from splashing into the cabinet and being blocked by the baffle, instead dripping down the inclined baffle into a collection box at the bottom. The baffle does not contact the lower louvers, thus maintaining ventilation and heat dissipation while preventing rainwater ingress. By controlling the rotation of the baffle with the miniature electric actuator, the design effectively prevents rainwater from entering the control cabinet and causing damage.

[0018] This utility model, by setting up a disassembly and assembly unit, allows the mounting frame to be removed from the outer end of the threaded rod by rotating the nut at the outer end of the threaded rod. This removes the mounting frame from the outer end of the electromechanical control cabinet, allowing the rectangular frame to be removed from the through slots at the lower left and right ends of the electromechanical control cabinet. This completes the disassembly of the rectangular frame, facilitating its quick removal from the lower end of the electromechanical control cabinet when maintenance of the ventilation mechanism is required, thus providing convenience for maintenance work.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is an electromechanical control cabinet, the structural diagram of which is shown below. Figures 1 to 4As shown, the device includes an electromechanical control cabinet body 1. The front end of the electromechanical control cabinet body 1 is hinged to a cabinet door 2. Ventilation mechanisms are provided at the lower left and right ends of the electromechanical control cabinet body 1. The ventilation mechanisms include rectangular frames 301 connected to the lower left and right ends of the electromechanical control cabinet body 1. A dustproof net 302 is installed on the left inner side of the rectangular frame 301. Inclined louver blades 303 are fixedly connected at equal intervals on the right inner side of the rectangular frame 301. A rotating shaft 304 is connected to the right end of the rectangular frame 301. Rotating holes are opened at the upper left side of the dustproof net 302 at both ends of the front end of the rectangular frame 301. The outer sides of the front and rear ends of the rotating shaft 304 are rotatably connected to the inner side of the rotating holes. The front and rear sides of the baffle 306 are slidably connected to the front and rear ends of the inner side of the rectangular frame 301. A gear 305 is fixedly connected to the outer front end of the rotating shaft 304. A baffle 306 is fixedly connected to the outer part of the rotating shaft 304 located inside the rectangular frame 301. A mounting plate 307 is fixedly connected to the right front side of the rectangular frame 301. A miniature electric push rod 308 is mounted on the upper end of the mounting plate 307. A protective cover 309 is fixedly connected to the upper side of the mounting plate 307 at the outer end of the miniature electric push rod 308. A rack 310 is fixedly connected to the lower end of the output shaft of the miniature electric push rod 308. The outer end of the rack 310 meshes with the outer end of the gear 305. Thus, when the output shaft of the miniature electric push rod 308 is activated, it moves, causing the rack 310 to move, which in turn causes the gear 305 to rotate, making the rotating shaft 304 rotate. This, in turn, causes the baffle 306 to rotate inside the rectangular frame 301.

[0029] Cooperate Figure 5 As shown, a collection unit is provided on the lower side of the rectangular frame 301. The collection unit includes a collection box 401 located below the rectangular frame 301. Sliding rods 402 are fixedly connected to the upper left and right sides of the collection box 401. An L-shaped rod 403 is symmetrically fixedly connected to the lower right end of the rectangular frame 301. The outer side of the sliding rod 402 is slidably connected to the inner side of the L-shaped rod 403. A stop block 404 is fixedly connected to the rear side of the L-shaped rod 403. The sliding rod 402 is an iron rod, and the stop block 404 is a magnetic rod. The rear side of the sliding rod 402 abuts against the front side of the stop block 404. A through-hole is provided at the lower end of the rectangular frame 301 above the collection box 401. Thus, after the sliding rod 402 at the upper end of the collection box 401 is slid to the inside of the L-shaped rod 403 and the sliding rod 402 contacts the front side of the stop block 404, the stop block 404 will attract the sliding rod 402, so that the collection box 401 is fixed between the L-shaped rods 403, thereby fixing the collection box 401 below the drainage port below the rectangular frame 301.

[0030] Cooperate Figure 6As shown, a disassembly unit is provided at the outer end of the rectangular frame 301. The disassembly unit includes threaded rods 501 fixedly connected to the lower front and rear ends of the left and right sides of the electromechanical control cabinet 1. Nuts 502 are threadedly connected to the outer side of the threaded rods 501. A mounting frame 503 is fixedly connected to the outer side of the rectangular frame 301. Through slots are opened at the lower left and right ends of the electromechanical control cabinet 1. The outer side of the rectangular frame 301 is slidably connected to the inner side of the through slots. A through mounting hole is opened at the middle position of the front and rear ends inside the mounting frame 503. The outer side of the threaded rods 501 is slidably connected to the inner side of the mounting hole. The left and right sides of the mounting frame 503 abut against the electromechanical control cabinet 1 and the side adjacent to the threaded rods 501. Thus, after sliding the rectangular frame 301 to the inside of the through groove, and the mounting frame 503 at the outer end contacts the left or right side of the electromechanical control cabinet 1, and at the same time, the threaded rod 501 passes through the mounting holes at the front and rear points inside the mounting frame 503, the nut 502 is then threaded to the outside of the threaded rod 501 and contacts the mounting frame 503. This fixes the mounting frame 503 to the left and right sides of the electromechanical control cabinet 1, and at the same time fixes the rectangular frame 301 into the through groove, thus completing the installation of the ventilation mechanism in the electromechanical control cabinet.

[0031] Working principle: When the electromechanical control cabinet 1 is used outdoors, and during rainy weather, the micro electric push rod 308 is activated to control the rack 310 to move downward, driving the gear 305 and the rotating shaft 304 to rotate counterclockwise until the baffle 306 rotates to the louver blades 303 perpendicular to the bottom of the baffle 306. This allows water droplets hitting the surface of the louver blades 303 to be blocked by the baffle 306 when splashing into the electromechanical control cabinet 1, and drip down the inclined baffle 306 into the collection box 401 at the bottom for collection. The collection box 401 below the rectangular frame 301 is periodically moved forward and removed from the bottom of the rectangular frame 301 to clean the rainwater. This can prevent rainwater from entering the electromechanical control cabinet 1 and causing damage during rainy weather.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
