Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, in particular to a safety switch cabinet. Background Art

[0002] A switch cabinet is a common electrical equipment, comprising a cabinet body, a front door and a rear door installed on the cabinet body, a main circuit breaker installed on the upper inner side of the cabinet body, a plurality of outgoing line circuit molded case circuit breakers installed on the lower inner side of the cabinet body, a bus mounting frame installed on the middle inner side of the cabinet body, a bus mounted on the bus mounting frame, a main conductor connected between the bus and the main circuit breaker, and a branch conductor connected between the bus and the outgoing line circuit molded case circuit breaker.

[0003] However, the above technical solution has the following disadvantages: 1. When the operator opens the front door or the rear door for maintenance or operates the switch, the bus is too close to the operator, the operator's movement space is limited, and the operation is inconvenient; 2. Moreover, the operator is prone to accidentally touch the bus, the risk of electric shock is high, and the safety is poor. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a safety switch cabinet to increase the activity space of operators when repairing or operating switches, reduce the risk of electric shock, and improve safety.

[0005] The purpose of the present invention is achieved through the following technical measures:

[0006] A safety switch cabinet comprises a cabinet body, a front door and a rear door are installed on the cabinet body, a main circuit breaker is installed on the upper inner part of the cabinet body, a plurality of outgoing line circuit molded case circuit breakers are installed on the lower inner part of the cabinet body, a bus mounting frame capable of horizontal movement is slidably connected to the middle inner part of the cabinet body, a bus is installed on the bus mounting frame, a main conductor is connected between the bus and the main circuit breaker, a branch conductor is connected between the bus and the outgoing line circuit molded case circuit breaker, an axle is installed on the side of the bus mounting frame, and a horizontally arranged strip groove for accommodating the axle to pass through is opened on the cabinet body.

[0007] Due to the adoption of the above technical solution, when it is necessary to open the front door, first, push the bus mounting frame to move backward, and the bus is away from the front door, thereby reducing the risk of electric shock and improving safety; when it is necessary to open the rear door, first, the operator pushes the bus mounting frame to move forward, and the bus is away from the rear door, thereby reducing the risk of electric shock and improving safety.

[0008] A front hanging pin is provided on the side of the front door, and a front operating panel is hinged on the outside of the cabinet body through a front rotating shaft, and a front contact portion that can contact the wheel axle is provided on the front operating panel, and the shape of the front contact portion is an arc shape, and the front rotating shaft is eccentrically arranged, and a front positioning groove that can cooperate with the wheel axle and a front hanging pin groove that can cooperate with the front hanging pin are provided on the side of the front operating panel away from the front rotating shaft; a rear hanging pin is provided on the side of the rear door, and a rear operating panel is hinged on the outside of the cabinet body through a rear rotating shaft, and a rear contact portion that can contact the wheel axle is provided on the rear operating panel, and the shape of the rear contact portion is an arc shape, and the rear rotating shaft is eccentrically arranged, and a rear positioning groove that can cooperate with the wheel axle and a rear hanging pin groove that can cooperate with the rear hanging pin are provided on the side of the rear operating panel away from the rear rotating shaft.

[0009] When the front door needs to be opened, first, the operator rotates the front operating panel, and the front hanging pin slot is disengaged from the front hanging pin. As the front operating panel rotates, the front contact portion approaches one of the axles and eventually contacts the axle; after the front contact portion contacts the axle, the front operating panel continues to rotate, and the front contact portion pushes the bus mounting frame backward, and the bus is away from the front door, reducing the risk of electric shock and improving safety. When the front operating panel rotates 180 degrees, the front positioning slot matches the axle, fixes the bus mounting frame, and the bus mounting frame stops moving.

[0010] Similarly, when the rear door needs to be opened, first, the rear operating panel is rotated, and the rear hanging pin slot is disengaged from the rear hanging pin. As the rear operating panel rotates, the rear contact portion pushes the busbar mounting frame forward, and the busbar is away from the rear door, reducing the risk of electric shock and improving safety. When the rear operating panel is rotated 180 degrees, the rear positioning slot cooperates with the wheel axle to fix the busbar mounting frame.

[0011] There are four wheel axles, two of which are located on one side of the bus mounting frame, and the other two are located on the other side of the bus mounting frame. When one wheel axle on the same side of the bus mounting frame cooperates with the front positioning groove and the rear hanging pin cooperates with the rear hanging pin groove, the other wheel axle on the same side can contact the side of the rear contact portion close to the rear rotating shaft; when one wheel axle on the same side of the bus mounting frame cooperates with the rear positioning groove and the front hanging pin cooperates with the front hanging pin groove, the other wheel axle on the same side can contact the side of the front contact portion close to the front rotating shaft.

[0012] When the front operating panel rotates to the right angle, the front positioning groove matches the axle to fix the busbar mounting frame, and the busbar mounting frame stops moving. At the same time, the other axle on the same side contacts the side of the rear contact part close to the rear shaft. At this time, if the rear operating panel is moved, the rear contact part cannot push the busbar mounting frame forward. Therefore, the rotation angle of the rear operating panel is small, and the rear hanging pin groove cannot be separated from the rear hanging pin. At this time, the rear door cannot be opened, and the front door can be opened normally, which improves safety.

[0013] Similarly, when the rear door needs to be opened, first, close the front door, turn the front operating panel, the front hanging pin slot matches the front hanging pin, and then turn the rear operating panel, the rear hanging pin slot disengages from the rear hanging pin. As the rear operating panel rotates, the rear contact portion pushes the busbar mounting frame forward, and the busbar moves away from the rear door, reducing the risk of electric shock and improving safety. When the rear operating panel rotates 180 degrees, the rear positioning groove matches the pulley axle to fix the busbar mounting frame. At this time, the front door cannot be opened, but the rear door can be opened normally, improving safety.

[0014] The front operating panel is connected with a front handle, and the rear operating panel is connected with a rear handle, which is convenient for the operator to hold and operate the front operating panel and the rear operating panel.

[0015] The wheel axle is rotatably connected with a pulley, and the side surface of the pulley is provided with an annular groove which can be matched with the front contact part or the rear contact part, thereby reducing the friction between the front contact part or the rear contact part and the wheel axle and improving the service life.

[0016] The wheel shaft is rotatably connected with a running wheel, and a guide rail that can match the running wheel is installed inside the cabinet. This structure is compact and convenient to manufacture and maintain.

[0017] There are four guide rails, two of which are located on one side of the cabinet, and the other two are located on the other side of the cabinet. The cross section of the guide rail is L-shaped, and the running wheel is located between the two guide rails on the same side. This structure is compact and convenient for manufacturing and maintenance.

[0018] The busbar mounting frame is in the shape of a rectangular frame, and the busbar is located inside the busbar mounting frame, thereby preventing operators from accidentally touching the busbar, reducing the risk of electric shock, and improving safety.

[0019] In summary, when the front door needs to be opened, the busbar mounting frame is located at the inner rear part of the cabinet, and when the rear door needs to be opened, the busbar mounting frame is located at the inner front part of the cabinet, which increases the movement space for operators when repairing or operating switches, reduces the risk of electric shock, and improves safety.

DETAILED DESCRIPTION

[0032] As attached Figure 1 As shown, a safety switch cabinet includes a cabinet 1, and a front door 7 and a rear door 9 are installed on the cabinet 1. The front door 7 and the rear door 9 are both made of existing technology and are not described in detail here. A main circuit breaker 8 is installed on the upper inner side of the cabinet 1, and a plurality of outgoing line circuit molded case circuit breakers 2 are installed on the lower inner side of the cabinet. The main circuit breaker 8 and the outgoing line circuit molded case circuit breakers 2 are both made of existing technology and are not described in detail here.

[0033] A busbar mounting frame 4 capable of horizontal movement is slidably connected to the middle of the inner side of the cabinet 1, and a busbar 5 is installed on the busbar mounting frame 4. A main conductor 6 is connected between the busbar 5 and the main circuit breaker 8, and a branch conductor 3 is connected between the busbar 5 and the outgoing line circuit molded case circuit breaker 2. The main conductor 6 and the branch conductor 3 are both made of existing technology, which will not be repeated here. Preferably, the main conductor 6 and the branch conductor 3 are made of copper wire, which has good flexibility. When the busbar mounting frame 4 moves, the main conductor 6 and the branch conductor 3 are not easy to break or detach from the main circuit breaker 8 and the outgoing line circuit molded case circuit breaker 2.

[0034] As attached Figure 2 As shown, specifically, the busbar mounting frame 4 is in the shape of a rectangular frame, and the busbar 5 is located inside the busbar mounting frame 4. Preferably, the number of the busbars 5 is two, one of which is mounted on the inside of the frame of the busbar mounting frame 4 close to the front door 7, and the other busbar 5 is mounted on the inside of the frame of the busbar mounting frame 4 close to the rear door 9. Regardless of whether the operator opens the front door or the rear door, the busbar is away from the operator, thereby improving safety.

[0035] As attached Figure 3 , 4 As shown in FIG5 , a wheel axle 16 is installed on the side of the bus mounting frame 4. Specifically, there are four wheel axles 16, two of which are located on one side of the bus mounting frame 4, and the other two are located on the other side of the bus mounting frame 4. A walking wheel 17 is rotatably connected to each wheel axle 16.

[0036] Correspondingly, a guide rail 19 capable of cooperating with the running wheel 17 is installed inside the cabinet 1. Specifically, there are four guide rails 19, two of which are located on one side of the cabinet 1, and the other two are located on the other side of the cabinet 1. The two guide rails 19 on the same side are arranged in sequence up and down, and are both arranged horizontally. The cross-section of the guide rail 19 is L-shaped, and the running wheel 17 is located between the two guide rails 19 on the same side.

[0037] A horizontally arranged strip groove 15 is provided on the side of the cabinet 1 for accommodating the wheel shaft 16 to pass through. There are two strip grooves 15, one of which is located on one side of the cabinet 1 and the other is located on the other side of the cabinet 1. One end of each wheel shaft 16 passing through the cabinet 1 is rotatably connected to a pulley 14, and a groove that can be annular is provided on the side of the pulley 14.

[0038] As attached Figure 6 , 7 As shown in FIG. 8 , a front hanging pin 11 is provided on the side of the front door 7 . There are two front hanging pins 11 , one of which is located on one side of the front door 7 and the other is located on the other side of the front door 7 .

[0039] A front operating panel 12 is hingedly connected to the outer side of the cabinet 1 through a front rotating shaft 13 . There are two front operating panels 12 , one of which is located at one side of the cabinet 1 and the other is located at the other side of the cabinet 1 .

[0040] The edge of the front operating plate 12 has a front contact portion 25 that can contact and cooperate with the groove on the pulley 14. The front contact portion 25 is in an arc shape, and the front rotating shaft 13 is eccentrically arranged. A front positioning groove 24 that can cooperate with the wheel shaft 16 and a front hanging pin groove 23 that can cooperate with the front hanging pin 11 are opened on the side of the front operating plate 12 away from the front rotating shaft 13.

[0041] The front operating panel 12 is connected to the front handle 10 .

[0042] A rear hanging pin 21 is provided on the side of the rear door 9 , and there are two rear hanging pins 21 , one rear hanging pin 21 is located on one side of the rear door 9 , and the other rear hanging pin 21 is located on the other side of the rear door 9 .

[0043] A rear operating panel 20 is hingedly connected to the outer side of the cabinet 1 through a rear rotating shaft 18 . There are two rear operating panels 20 , one of which is located at one side of the cabinet 1 and the other is located at the other side of the cabinet 1 .

[0044] The edge of the rear operating plate 20 has a rear contact portion 28 that can contact and cooperate with the groove on the pulley 14. The shape of the rear contact portion 28 is an arc shape, and the rear shaft 18 is eccentrically arranged. The side of the rear operating plate 20 away from the rear shaft 18 is provided with a rear positioning groove 27 that can cooperate with the wheel shaft 16 and a rear hanging pin groove 26 that can cooperate with the rear hanging pin 21.

[0045] A rear handle 22 is connected to the rear operating panel 20 .

[0046] When one axle 16 on the same side of the busbar mounting frame 4 cooperates with the front positioning groove 24 and the rear hanging pin 21 cooperates with the rear hanging pin groove 26 , the other axle 16 on the same side can contact the side of the rear contact portion 28 close to the rear rotating shaft 18 .

[0047] When one axle 16 on the same side of the busbar mounting frame 4 cooperates with the rear positioning groove 27 and the front hanging pin 11 cooperates with the front hanging pin groove 23 , the other axle 16 on the same side can contact the side of the front contact portion 25 close to the front rotating shaft 13 .

[0048] As attached Fig. 9 , 10 As shown, when the front door needs to be opened, first, the operator holds a front handle 10 with both hands, or two operators hold a front handle 10 respectively; then, the front operating plate 12 is rotated, and the front hanging pin slot 23 is disengaged from the front hanging pin 11.

[0049] As the front operating panel 12 rotates, the front contact portion 25 approaches one of the pulleys 14 and finally contacts the pulley 14; after the front contact portion 25 contacts the pulley 14, the front operating panel 12 continues to rotate, and the front contact portion 25 pushes the bus mounting frame 4 to move backward, and the bus 5 is away from the front door 7, thereby reducing the risk of electric shock and improving safety.

[0050] When the front operating panel 12 rotates 180 degrees, the front positioning groove 24 cooperates with the pulley 14 to fix the busbar mounting frame 4, and the busbar mounting frame 4 stops moving. At the same time, the other pulley 14 on the same side contacts the side of the rear contact portion 28 close to the rear shaft 18. At this time, if the rear operating panel 20, the rear contact portion 28 cannot push the busbar mounting frame 4 forward, therefore, the rotatable angle of the rear operating panel 20 is small, and the rear hanging pin groove 26 cannot be separated from the rear hanging pin 21. At this time, the rear door 9 cannot be opened, and the front door 7 can be opened normally.

[0051] Similarly, when the rear door 9 needs to be opened, first, the front door 7 is closed, the front operating plate 12 is rotated, the front hanging pin slot 23 is matched with the front hanging pin 11, and then, the rear operating plate 20 is rotated, and the rear hanging pin slot 26 is disengaged from the rear hanging pin 21.

[0052] As the rear operating panel 20 rotates, the rear contact portion 28 pushes the busbar mounting frame 4 to move forward, and the busbar 5 is away from the rear door 7, thereby reducing the risk of electric shock and improving safety.

[0053] When the rear operating panel 20 rotates 180 degrees, the rear positioning groove 27 cooperates with the pulley 14 to fix the busbar mounting frame 4. At this time, the front door 7 cannot be opened, but the rear door 9 can be opened normally.

[0054] In summary, the present invention is not limited to the above specific embodiments. Those skilled in the art may make several changes and modifications without departing from the spirit and scope of the present invention, and all these changes should fall within the protection scope of the present invention.
