Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical equipment safety, and in particular to a safety protection device for electromechanical equipment. Background Art

[0002] Electromechanical equipment generally refers to the collective name of machinery, electrical appliances and electrical automation equipment. In construction, it mostly refers to the collective name of machinery and piping equipment other than geotechnical, carpentry, steel bars and mud and water. As an important component of the electromechanical equipment control system, the electrical control box is usually used to install various electrical components and controllers to achieve control, protection and monitoring of electromechanical equipment.

[0003] The electrical control box needs to be installed outdoors under certain circumstances. However, due to the lack of safety protection devices outdoors, when encountering strong winds, debris on the ground will be rolled up and dropped on the outside of the electrical control box, causing damage to the electrical control box. In more serious cases, external wind and sand will be blown into the electrical control box through the ventilation slots of the electrical control box, which can easily cause damage to internal components and cause losses.

[0009] According to the above technical scheme, the protective assembly includes a positioning frame, a sealing plate, a spring, a protective plate, a mobile extrusion frame, an extrusion plate, a rubber pulley, a protective slide groove and a rubber patch. The positioning frame is fixedly connected to the bottom of the inner side of the electrical control box, the sealing plate is rotatably connected to the middle part of the positioning frame, the spring is fixedly connected to the left side of the sealing plate, the protective plate is fixedly connected to the other end of the spring, the mobile extrusion frame is fixedly connected to the side of the protective plate close to the outer wall of the electrical control box, the extrusion plate is rotatably connected to the middle part of the mobile extrusion frame, the rubber pulley is rotatably connected to the outside of the extrusion plate, the protective slide groove is fixedly connected to the left side of the sealing plate, and the rubber patch is fixedly connected to the right side of the protective slide groove.

[0010] According to the above technical solution, sliding grooves are provided at the bottom and top of the electrical control box, the top of the ball nut pair is arranged in the sliding groove, the fixed sliding groove is arranged at the top of the sliding groove, the slider is arranged inside the fixed sliding groove, and the slider is slidably connected to the fixed sliding groove, a guide rod is fixedly connected to the middle part of the fixed sliding groove, a guide hole is provided in the middle part of the slider, and the slider is slidably connected to the guide rod in the fixed sliding groove through the guide hole, so that the slider can slide in the fixed sliding groove.

[0011] According to the above technical solution, the second adjustment frame is fixedly connected to the outer wall of the sealing plate on the side away from the second rotating block, and a ventilation groove is provided on the outside of the electrical control box to accommodate the movement of the protective plate. By setting the ventilation groove, ventilation can be performed inside the electrical control box.

[0012] According to the above technical solution, the rubber pulley is arranged in the protective slide groove, and one side of the rubber pulley is continuously in contact with one side of the rubber patch. The rubber pulley is slidably connected to the rubber patch, so that the rubber pulley slides on the surface of the rubber patch.

[0013] According to the above technical solution, the spring, protective plate, movable extrusion frame, extrusion plate, rubber pulley, protective slide groove and rubber patch are all arranged in the ventilation groove, so that the protective plate can be moved to the outside of the electrical control box to protect the outside of the electrical control box.

[0014] Compared with the prior art, the beneficial effect achieved by the present invention is as follows: in the case of strong winds, the outer side of the electrical control box needs to be protected. At this time, the driving motor is controlled to work, and the driving motor drives the bidirectional threaded rod to rotate when the driving motor works. At this time, the ball nut pair moves on the outer side of the bidirectional threaded rod, so that the ball nut pair is close to the inner wall of the electrical control box. At this time, the ball nut pair drives the slider to move, and the slider slides on the guide rod in the fixed slide groove, so that the movable extension plate moves synchronously with the slider, so that the adjustment frame 1 on the top of the movable extension plate pushes the rotating block 1 and the telescopic rod to rotate the rotating block 1, and the telescopic rod is extended and retracted at the same time, and the telescopic rod pushes the rotating block 2 and the adjusting frame 2 to make the sealing plate rotate in the positioning frame, and at this time, the sealing plate moves to fit with the inner wall of the electrical control box, so that the sealing plate blocks the ventilation slots opened on the outer wall of the electrical control box, so as to prevent the external wind and sand from entering the interior of the electrical control box through the ventilation slots during strong winds, and to prevent the components in the electrical control box from being damaged;

[0015] When the sealing plate rotates to fit with the inner wall of the electrical control box, the protective plate moves to the outside of the electrical control box through the ventilation slot, so that the debris rolled up from the ground in windy weather outside will first contact the protective plate. By setting the spring, the protective plate can be buffered when it is hit. At the same time, when the protective plate is hit, the protective plate is moved. At this time, the mobile extrusion frame on the protective plate moves accordingly, so that the mobile extrusion frame squeezes the extrusion plate, so that the rubber pulley slides on the rubber patch in the protective slide groove, and the impact force is converted into friction force when the rubber pulley moves on the surface of the rubber patch. By setting the rubber patch, the resistance of the rubber pulley when moving can be increased, and then the force generated during the impact can be buffered, thereby reducing the damage to the protective plate when it is hit.

[0016] When the sealing plate closes the ventilation slots on the electrical control box, both sides of the electrical control box are blocked. At the same time, due to the strong wind outside, the outside air is poured in through the sliding slots on the top of the electrical control box, and the air flows out through the sliding slots at the bottom of the electrical control box, so as to avoid the slow internal heat dissipation efficiency of the electrical control box after closing both sides. When the strong wind ends, the two-way threaded rod is controlled to work to move the ball nut pair away from the left and right inner walls of the electrical control box. At this time, the sealing plate rotates in the positioning frame toward the top and bottom inner walls of the electrical control box, and the ventilation slots on both sides of the electrical control box are opened to ensure the ventilation of the electrical control box at normal times.

[0033] The electrical control box 2 is provided with sliding grooves at the bottom and the top, the top of the ball nut pair 404 is arranged in the sliding groove, the fixed sliding groove 501 is arranged at the top of the sliding groove, the slider 405 is arranged inside the fixed sliding groove 501, and the slider 405 is slidably connected to the fixed sliding groove 501, a guide rod is fixedly connected to the middle part of the fixed sliding groove 501, a guide hole is provided in the middle part of the slider 405, the slider 405 is slidably connected to the guide rod in the fixed sliding groove 501 through the guide hole, so that the slider 405 can slide in the fixed sliding groove 501.

A ventilation slot is provided on the outside of the electrical control box 2 to accommodate the movement of the protective plate 604. By setting the ventilation slot, ventilation can be performed inside the electrical control box 2.

[0035] The rubber pulley 607 is arranged in the protective slide groove 608 , and one side of the rubber pulley 607 is continuously in contact with one side of the rubber patch 609 . The rubber pulley 607 is slidably connected with the rubber patch 609 , so that the rubber pulley 607 slides on the surface of the rubber patch 609 .

[0036] The spring 603, the protective plate 604, the movable extrusion frame 605, the extrusion plate 606, the rubber pulley 607, the protective slide groove 608 and the rubber patch 609 are all arranged in the ventilation groove, so that the protective plate 604 can be moved to the outside of the electrical control box 2 to protect the outside of the electrical control box 2.

[0037] When encountering strong winds, it is necessary to protect the outside of the electrical control box 2. At this time, the control driving motor 402 is operated, and the driving motor 402 drives the bidirectional threaded rod 403 to rotate. At this time, the ball nut pair 404 moves outside the bidirectional threaded rod 403, so that the ball nut pair 404 is close to the inner wall of the electrical control box 2. At this time, the ball nut pair 404 drives the slider 405 to move, and the slider 405 slides on the guide rod in the fixed slide groove 501, so that the movable extension plate 406 moves synchronously with the slider 405, so that the top of the movable extension plate 406 The adjusting frame 1 502 pushes the rotating block 1 503 and the telescopic rod 504 to rotate the rotating block 1 503, and at the same time the telescopic rod 504 is extended and retracted, and the telescopic rod 504 pushes the rotating block 2 505 and the adjusting frame 2 506 to rotate the sealing plate 602 in the positioning frame 601.

[0038] When the sealing plate 602 rotates to fit the inner wall of the electrical control box 2, the protective plate 604 moves to the outside of the electrical control box 2 through the ventilation slot, so that the debris rolled up from the ground in windy weather outside will first contact the protective plate 604.

At this time, the mobile extrusion frame 605 on the protective plate 604 moves accordingly, so that the mobile extrusion frame 605 squeezes the extrusion plate 606, so that the rubber pulley 607 slides on the rubber patch 609 in the protective slide groove 608, and the impact force is converted into the friction force of the rubber pulley 607 when it moves on the surface of the rubber patch 609. By setting the rubber patch 609, the resistance of the rubber pulley 607 when it moves can be increased, thereby buffering the force generated during the impact, thereby reducing the damage to the protective plate 604 when it is hit.

[0039] When the sealing plate 602 closes the ventilation slots on the electrical control box 2, both sides of the electrical control box 2 are blocked. At the same time, due to the strong wind outside, the outside air is poured in through the sliding slots on the top of the electrical control box 2, and the air is made to flow out through the sliding slots at the bottom of the electrical control box 2, so as to avoid the slow internal heat dissipation efficiency of the electrical control box 2 after closing both sides. When the strong wind ends, the bidirectional threaded rod 403 is controlled to work, so that the ball nut pair 404 moves away from one side of the left and right inner walls of the electrical control box 2. At this time, the sealing plate 602 rotates toward the top and bottom inner walls of the electrical control box 2 in the positioning frame 601, and the ventilation slots on both sides of the electrical control box 2 are opened to ensure the ventilation of the electrical control box 2 at normal times.
