Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to an electrical safety switchgear. Background Technology

[0002] The main function of electrical safety switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes of a power system. Electrical safety switchgear, in accordance with the requirements of the primary electrical wiring diagram, rationally assembles high and low voltage electrical equipment such as circuit breakers, disconnectors, instrument transformers, busbars, current-carrying conductors, and insulators, as well as related control, measurement, signaling, protection, and regulation devices, within a closed or open metal cabinet.

[0003] Many existing electrical safety switch cabinets require operators to go deep inside the cabinet to install and maintain electrical equipment. However, the internal space of electrical safety switch cabinets is usually quite narrow, which increases the difficulty and complexity of operation. This not only increases the complexity of operation but may also pose a safety hazard to the operators. Utility Model Content

[0004] The purpose of this invention is to provide an electrical safety switch cabinet that improves operational safety and solves the problem of poor operational safety in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrical safety switch cabinet includes a cabinet body. Two sliding grooves are provided on the inner wall of the cabinet body. Two sliders are slidably connected inside the sliding grooves. A connecting seat is fixedly connected to the side wall of each slider. A cylindrical column is slidably connected inside the side wall of the cabinet body. A movable rod is slidably connected inside the cylindrical column. A spring is fixedly connected between the side wall of the movable rod and the inner wall of the cylindrical column. A movable plate is slidably disposed inside the cabinet body. Multiple mounting plates are fixedly connected at equal intervals to the side wall of the movable plate. Multiple connecting blocks are fixedly connected to the side wall of the movable plate. A connecting plate is rotatably connected between the connecting blocks and the connecting seat. A crossbar is fixedly connected between the side wall of the movable plate and the side wall of the cylindrical column. The crossbar is slidably connected to the inner wall of the cabinet body. A side door is rotatably disposed on one side of the cabinet body. A protrusion is fixedly connected to the side wall of the side door. A slot is provided on the side wall of the protrusion. A movable rod is slidably connected to the slot.

[0007] Preferably, the cabinet sidewall is provided with multiple through holes and slots, and the cabinet inner wall is provided with multiple wire grooves, the through holes and slots being connected to the wire grooves.

[0008] Preferably, a screw is rotatably connected inside the slide groove, and two synchronous gears are rotatably connected inside the side wall of the cabinet. The side wall of the synchronous gear is fixedly connected to the end of the screw, and the screw is threadedly connected to the slider.

[0009] Preferably, a synchronous belt is provided on the outside of both synchronous gears, a motor is fixedly connected inside the side wall of the cabinet, and the output end of the motor is fixedly connected to the side wall of one of the synchronous gears.

[0010] Preferably, a stop block is fixedly connected to the inner wall of the cabinet, and the side wall of the stop block cooperates with the side wall of the movable plate.

[0011] Preferably, the movable plate has multiple threading holes on its left side and multiple slots on its front side, the slots being connected to the threading holes.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. One of the synchronous gears is driven by a motor to rotate, and then the other synchronous belt is driven to rotate synchronously. At the same time, the synchronous gear drives the screw to rotate, and the two sliders slide outward relative to each other. Through the cooperation of the connecting seat, connecting plate and connecting block, the movable plate slides laterally. When the side wall of the slider is in contact with the inner wall of the slide groove, the movable plate slides to the cabinet outlet side. At this time, the mounting plate is located outside the cabinet, and the movable plate can automatically slide out of the cabinet. This eliminates the need for operators to enter the cabinet to install electrical equipment, which greatly reduces the risk of operators working in narrow spaces and reduces the possibility of accidental injury.

[0014] 2. During the installation of electrical equipment, the movable rod is located inside the slot, effectively locking the side door and preventing it from being accidentally touched or opened during operation. This ensures the safety of operators when performing installation work inside the cabinet and avoids potential risks caused by the sudden rotation of the side door. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6An electrical safety switch cabinet includes a cabinet body 001. Two sliding grooves 103 are provided on the inner wall of the cabinet body 001. Two sliders 104 are slidably connected inside the sliding grooves 103. Connecting seats 105 are fixedly connected to the side walls of the sliders 104. A cylindrical column 111 is slidably connected inside the side wall of the cabinet body 001. A movable rod 112 is slidably connected inside the cylindrical column 111. A spring 113 is fixedly connected between the side wall of the movable rod 112 and the inner wall of the cylindrical column 111. A movable plate 002 is slidably disposed inside the cabinet body 001. Multiple mounting plates 201 are fixedly connected at equal intervals to the side wall of the movable plate 002. There are multiple connecting blocks 204, and a connecting plate 205 is rotatably connected between the connecting blocks 204 and the connecting seat 105. A crossbar 206 is fixedly connected between the side wall of the movable plate 002 and the side wall of the cylindrical column 111, and the crossbar 206 is slidably connected to the inner wall of the cabinet 001. A side door 003 is rotatably located on one side of the cabinet 001. A protrusion 301 is fixedly connected to the side wall of the side door 003, and a slot 302 is provided on the side wall of the protrusion 301. The movable rod 112 is slidably connected to the slot 302. When electrical equipment needs to be installed, the operator rotates and opens the side door 003, exposing the exit of the cabinet 001. Then two The slider 104 slides outward relative to the other side, and at the same time, the slider 104 drives the connecting seat 105 to slide. The connecting seat 105 pushes the connecting plate 205, causing the connecting plate 205 to gradually rotate. At the same time, the connecting plate 205 pushes the connecting block 204, causing the movable plate 002 to slide laterally. When the side wall of the slider 104 is in contact with the inner wall of the slide groove 103, the movable plate 002 slides to the outlet side of the cabinet 001. At this time, the mounting plate 201 is located outside the cabinet 001. Then, the operator installs the electrical equipment to the side wall of the mounting plate 201 with bolts. During the sliding process of the movable plate 002, the movable plate 002 pushes the cylinder 111 to slide through the crossbar 206. When the movable rod 112 slides into the slot 302, the end of the movable rod 112 then fits against the inner wall of the slot 302. As the movable plate 002 continues to slide, part of the movable rod 112 gradually slides into the cylinder 111. At the same time, the spring 113 is compressed. When the mounting plate 201 slides out to the outside of the cabinet 001, the movable plate 002 stops sliding, and the cylinder 111 stops sliding. At this time, part of the movable rod 112 is located inside the cylinder 111, and the other part of the movable rod 112 is located inside the slot 302, which limits the side door 003 to prevent it from being accidentally rotated when installing electrical equipment.

[0024] Multiple slots 101 are provided through the side wall of the cabinet 001, and multiple wire grooves 102 are provided on the inner wall of the cabinet 001. The slots 101 and the wire grooves 102 are connected. When the operator passes the connecting wire through the slot 101, the connecting wire is stored in the wire groove 102 when the movable plate 002 slides into the cabinet 001. The connecting wire is stored in the wire groove 102.

[0025] A screw 107 is rotatably connected inside the slide 103. Two synchronous gears 108 are rotatably connected inside the side wall of the cabinet 001. The side wall of the synchronous gear 108 is fixedly connected to the end of the screw 107. The screw 107 is threadedly connected to the slider 104. The synchronous gear 108 drives the screw 107 to rotate. The side wall of the screw 107 is provided with positive and negative threads. The two sliders 104 correspond to the positive and negative threads. When the screw 107 rotates, the two sliders 104 slide inward or outward relative to each other.

[0026] Two synchronous gears 108 are connected to a synchronous belt 109 on their exterior. A motor 106 is fixedly connected inside the side wall of the cabinet 001. The output end of the motor 106 is fixedly connected to the side wall of one of the synchronous gears 108. The motor 106 drives one of the synchronous gears 108 to rotate, and then the synchronous belt 109 drives the other synchronous belt 109 to rotate synchronously.

[0027] A stop block 110 is fixedly connected to the inner wall of the cabinet 001. The side wall of the stop block 110 cooperates with the side wall of the movable plate 002. The movable plate 002 slides into the cabinet 001. The side wall of the stop block 110 fits against the side wall of the movable plate 002, so that there is an appropriate gap between the side wall of the movable plate 002 and the inner wall of the cabinet 001.

[0028] Multiple wire holes 203 are provided on the left side of the movable plate 002, and multiple slots 202 are provided on the front side of the movable plate 002. The slots 202 are connected to the wire holes 203. After the connecting wire passes through the slot 101, it passes through the wire hole 203 and slides into the slot 202. Then the operator pulls the connecting end of the connecting wire out from the slot 202 and connects it to the electrical equipment.

[0029] In this invention, when electrical equipment needs to be installed, the operator rotates and opens the side door 003, exposing the exit of the cabinet 001. The motor 106 drives one of the synchronous gears 108 to rotate, which in turn is driven by a synchronous belt 109, causing the other synchronous belt 109 to rotate synchronously. Simultaneously, the synchronous gear 108 drives the screw 107 to rotate, causing the two sliders 104 to slide outwards relative to each other. At the same time, the sliders 104 drive the connecting seat 105 to slide, and the connecting seat 105 pushes the connecting plate 205, causing the connecting plate 205 to gradually rotate. Simultaneously, the connecting plate 205 pushes the connecting block 204, causing the movable plate 002 to slide laterally. When the side wall of the slider 104 is in contact with the inner wall of the slide groove 103, the movable plate 002 slides to the exit side of the cabinet 001. At this point, the mounting plate 201 is located outside the cabinet 001. The operator then installs the electrical equipment onto the side wall of the mounting plate 201 using bolts, thus avoiding the need for the operator to enter the cabinet 001 for installation.

[0030] The cabinet 001 houses an electrical control system (such as a PLC controller, relay module, circuit breaker, etc.). This system receives control signals from the outside or preset programs through connecting lines. Electrical equipment (such as switches, contactors, sensors, etc.) serve as input or output elements of the control system and are connected to external electrical appliances (such as motors, lamps, heaters, etc.) through connecting lines. The electrical control system controls the electrical equipment according to the received signals or programs, thereby realizing operations such as starting, stopping, and adjusting external electrical appliances.

[0031] During the sliding process of the movable plate 002, the movable plate 002 pushes the cylinder column 111 to slide through the crossbar 206. The movable rod 112 slides into the slot 302, and then the end of the movable rod 112 fits against the inner wall of the slot 302. As the movable plate 002 continues to slide, part of the movable rod 112 gradually slides into the cylinder column 111. At the same time, the spring 113 is compressed. When the mounting plate 201 slides out to the outside of the cabinet 001, the movable plate 002 stops sliding, and the cylinder column 111 stops sliding. At this time, part of the movable rod 112 is located inside the cylinder column 111, and the other part of the movable rod 112 is located inside the slot 302, which limits the side door 003 and prevents the side door 003 from being accidentally turned when installing electrical equipment.

[0032] The operator inserts the connecting wire through the slot 101, then through the wire hole 203, and slides it into the slot 202. The operator then pulls the connecting end of the connecting wire out from the slot 202 and connects it to the electrical equipment. The connecting wire is reserved with a length that matches the size of the wire slot 102 so that it can be stored when the movable plate 002 slides.

[0033] After the electrical equipment is installed, the motor 106 drives one of the synchronous gears 108 to rotate in the opposite direction. Then, through the synchronous belt 109, the other synchronous belt 109 rotates synchronously. At the same time, the synchronous gear 108 drives the screw 107 to rotate, and the two sliders 104 slide inward relative to each other. Simultaneously, the sliders 104 drive the connecting seat 105 to slide. The connecting seat 105 pulls the connecting plate 205, causing the connecting plate 205 to rotate gradually. At the same time, the connecting plate 205 pulls the connecting block 204, causing the movable plate 002 to slide into the cabinet 001 until the side wall of the movable plate 002 is in contact with the side wall of the abutment block 110. When the movable plate 002 can no longer slide, the motor 106 stops rotating. During this process, the reserved length of the connecting wire connected to the electrical equipment slides into the wire groove 102.

[0034] During the sliding process of the movable plate 002, the movable plate 002 pulls the cylinder column 111 to slide through the crossbar 206. The energy of the spring 113 is gradually released. After the compressed energy of the spring 113 is completely released, it pulls the movable rod 112 to slide, so that part of the movable rod 112 slides out completely from the inside of the slot 302. When the movable plate 002 stops sliding, the movable rod 112 slides inside the side wall of the cabinet 001, thereby releasing the restriction on the side door 003.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
