Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a modular assembled outdoor distribution box based on electric shock prevention. Background Art

[0002] According to the requirements of electrical wiring, a 0.4KV distribution box assembles switchgear, measuring instruments, protective electrical appliances, auxiliary equipment, etc. in a closed or semi-closed metal cabinet or screen to form a complete set of low-voltage power distribution devices. During normal operation, the circuit can be switched on or off manually or automatically; once a fault or abnormal operation occurs, the protective electrical appliance will immediately cut off the circuit or send an alarm signal. In addition, the measuring instrument can also display various parameters during operation in real time and adjust some electrical parameters.

[0003] The existing device cannot isolate the external wiring, increasing the risk of electric shock and endangering personal safety, and it is difficult to prevent dust and water vapor from entering the distribution box body, resulting in affecting the operation of electrical equipment and reducing the safety and stability of the power distribution system. Summary of the Utility Model

[0004] The utility model discloses a modular assembled outdoor distribution box based on electric shock prevention, aiming to solve the technical problems that the existing device cannot isolate the external wiring, increases the risk of electric shock, is difficult to prevent dust and water vapor from entering the box, affects the operation of the equipment, and reduces the safety and stability of the power distribution system.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A modular assembled outdoor distribution box based on electric shock prevention, including a distribution box, an external wiring electric shock prevention component is arranged at the rear side of the distribution box, the external wiring electric shock prevention component includes a connecting cylinder, and a hole is opened at the rear side of the distribution box, and a fixed connection is arranged between the front end of the hole and the bottom end of the connecting cylinder. The front end of the connecting cylinder is fixedly connected with an anti-electricity shell frame, an annular member is arranged inside the anti-electricity shell frame, a plurality of convex holes are opened on the inner side of the annular member, and movable members are movably connected inside the convex holes. Compression springs are fixedly connected to the opposite sides of the movable members, arc-shaped anti-electricity plates are fixedly connected to the front ends of the compression springs. Circular sliding grooves are opened on the opposite sides of the movable members, expansion and contraction springs are arranged inside the sliding grooves, the bottom ends of the movable members are bolted with connecting members, the plurality of connecting members are arranged at intervals in a surrounding manner, and the bottom end of the lowermost connecting member is bolted with a telescopic driving rod, and a bolt connection is arranged between the bottom end of the telescopic driving rod and the inner side of the bottom end of the anti-electricity shell frame.

[0006] By providing a distribution box and an external wiring anti-electric shock component, when the distribution box protects the external wiring, when the external wiring needs to be connected to the distribution box, the external wiring is passed through the connecting cylinder. Since the connecting cylinder is fixedly connected to the hole at the rear side of the distribution box, the external wiring smoothly enters the inside of the anti-electricity housing frame. When it is necessary to protect the external wiring, the telescopic drive rod starts to work and extends upward. The telescopic drive rod pushes the connecting piece upward, and then drives the movable piece located below the annular piece to move upward. As the lower movable piece moves upward, the expansion and contraction spring starts to expand outward as a whole. Since multiple movable pieces are all connected to the outer side of the expansion and contraction spring, this will cause all the movable pieces to move relatively closer to the center of the annular piece in the convex hole during the process of the expansion and contraction spring expanding outward as a whole. The relative movement of the movable pieces will compress the compression spring. The elastic force generated after the compression spring is compressed causes the arc-shaped anti-electricity plate to move closer to the center position and gradually wrap the external wiring. When the telescopic drive rod extends to a certain extent, the expansion and contraction spring and the compression spring reach a new balance state, and the arc-shaped anti-electricity plate closely fits on the surface of the external wiring, forming a wrapping of the external wiring and playing a role in protecting against electric shock. At this time, the external wiring is protected by the arc-shaped anti-electricity plate in the anti-electricity housing frame, reducing the risk of electric shock. During the process, the external wiring can be isolated from the outside world, greatly reducing the risk of accidental contact with the external wiring by personnel and causing electric shock, protecting personal safety. It can also prevent dust, water vapor, etc. from entering the inside of the distribution box to a certain extent, affecting the normal operation of electrical equipment, and improving the safety and stability of the entire power distribution system.

[0007] In a preferred solution, a protective shell is fixedly connected to the outside of the anti-electricity housing frame, a bottom frame is fixedly connected to the bottom end of the anti-electricity housing frame, and the front end of the bottom frame is fixedly connected to the rear end of the distribution box body. A cabinet door is fixedly connected to the front end of the distribution box, a handle is fixedly connected to the front end of the cabinet door, and an observation window is fixedly connected to the front end of the distribution box. A telescopic base is fixedly connected to the bottom end of the distribution box, and a radiator is fixedly connected to one side of the distribution box.

[0008] In a preferred embodiment, a rainproof elevation assembly is provided inside the telescopic base. The rainproof elevation assembly includes a bottom plate, the top end of the bottom plate is fixedly connected to the inner top end of the telescopic base, and upper rods are movably connected to the outer sides of both ends of the bottom plate. Connecting rods are movably connected between the inner sides of two symmetric upper rods. Lower rods are movably connected to the outer sides of both ends of the two connecting rods. The bottom ends of the lower rods are movably connected to the bottom ends of the fixed rods, and the bottom ends of the fixed rods are fixedly connected to the inner side of the bottom end of the telescopic base. A bidirectional drive motor is provided below the bottom plate. The power output shafts at both ends of the bidirectional drive motor are connected to rotating threaded rods through couplings. The outer sides of the rotating threaded rods are movably connected to the inner sides of the connecting rods. Connecting frames are fixedly connected to the ends of the two rotating threaded rods away from the bidirectional drive motor. Auxiliary rods are fixedly connected to the opposite sides of the connecting frames. The outer sides of the auxiliary rods are movably connected to the inner sides of the connecting rods. The bottom ends of the connecting frames are fixedly connected to the inner side of the bottom end of the telescopic base.

[0009] By providing a rainproof elevation assembly, when the rainproof elevation assembly elevates the distribution box during rain, in order to prevent rainwater from entering the distribution box, the bidirectional drive motor is started. The bidirectional drive motor drives the rotating threaded rods to rotate synchronously. Since the outer sides of the rotating threaded rods are movably connected to the inner sides of the connecting rods, the rotation of the rotating threaded rods causes the connecting rods to start moving along the axial direction of the threaded rods. At the same time, the auxiliary rods also play a certain guiding and supporting role for the connecting rods to ensure the stability of their movement. As the connecting rods move, the upper rods and lower rods movably connected to them start to change angles. Because one end of the upper rod is movably connected to the bottom plate, one end of the lower rod is movably connected to the fixed rod, and the upper rod, lower rod and connecting rod are all movably connected. The movement of the connecting rod causes the upper rod to move upward. Since the top end of the upper rod is connected to the inner top end of the telescopic base, the upward movement of the upper rod will drive the telescopic base and the distribution box installed on it to be lifted upward as a whole. During this process, the lower rod will also change its angle accordingly to adapt to the upward movement of the upper rod while maintaining the stability of the entire structure. When the bidirectional drive motor rotates to a certain extent and the rotating threaded rods rotate a corresponding number of turns, the connecting rods move to a predetermined position, and the upper rod lifts the distribution box to a suitable height. At this time, rainwater is not easily introduced into the interior of the distribution box, achieving the purpose of rain protection. After the distribution box is lifted to the predetermined height, the bidirectional drive motor stops working, the rotating threaded rods no longer rotate, and the relative positions between the various rods are fixed, and the distribution box continues to work at the lifted position.

[0010] As can be seen from the above, a modular assembled outdoor distribution box based on electric shock prevention provided by the present utility model has the technical effects of isolating external wiring, reducing the risk of electric shock to ensure personal safety, preventing dust and water vapor from entering the distribution box body, avoiding affecting the operation of electrical equipment, and improving the safety and stability of the power distribution system.

[0021] Refer to Figure 2 , Figure 3 and Figure 5, in a preferred embodiment, a rainproof elevation assembly 9 is provided inside the telescopic base 6.

[0022] Working principle: When the distribution box protects the external wiring, when the external wiring needs to be connected to the distribution box, the external wiring is passed through the connecting cylinder 704. Since the connecting cylinder 704 is fixedly connected to the hole at the rear side of the distribution box, the external wiring smoothly enters the inside of the anti-electricity housing frame 701. When it is necessary to protect the external wiring, the telescopic driving rod 702 starts to work and extends upward. The telescopic driving rod 702 pushes the connecting member 703 upward, thereby driving the movable member 706 located below the annular member 705 to move upward. As the lower movable member 706 moves upward, the expansion and contraction spring 709 starts to expand outward as a whole. Since multiple movable members 706 are all connected to the outer side of the expansion and contraction spring 709, this will cause all the movable members 706 to move relatively closer to the center of the annular member 705 in the convex hole during the process of the expansion and contraction spring 709 expanding outward as a whole. The relative movement of the movable member 706 will compress the compression spring 707. The elastic force generated after the compression spring 707 is compressed causes the arc-shaped anti-electricity plate 708 to move closer to the center position and gradually wrap the external wiring. When the telescopic driving rod 702 extends to a certain extent, the expansion and contraction spring 709 and the compression spring 707 reach a new equilibrium state, and the arc-shaped anti-electricity plate 708 closely fits on the surface of the external wiring, forming a wrapping of the external wiring and playing a role in protecting against electric shock. At this time, the external wiring is protected by the arc-shaped anti-electricity plate 708 in the anti-electricity housing frame 701, reducing the risk of electric shock;When it rains, the rainproof elevation component 9 elevates the distribution box. When it rains, in order to prevent rainwater from entering the distribution box, the bidirectional drive motor 902 starts. The bidirectional drive motor 902 drives the rotating threaded rod 903 to rotate synchronously. Since the outer side of the rotating threaded rod 903 is movably connected to the inner side of the connecting rod member 905, the rotation of the rotating threaded rod 903 causes the connecting rod member 905 to start moving along the axial direction of the threaded rod. At the same time, the auxiliary rod 904 also plays a certain guiding and supporting role for the connecting rod member 905 to ensure the stability of its movement. As the connecting rod member 905 moves, the upper rod 907 and the lower rod 908 movably connected to it start to change their angles. Because one end of the upper rod 907 is movably connected to the bottom plate 901, one end of the lower rod 908 is movably connected to the fixed rod member 909, and the upper rod 907, the lower rod 908 and the connecting rod member 905 are all movably connected. The movement of the connecting rod member 905 causes the upper rod 907 to move upward. Since the top end of the upper rod 907 is connected to the inside of the top end of the telescopic base 6, the upward movement of the upper rod 907 will drive the telescopic base 6 and the distribution box installed on it to be elevated upward as a whole. During this process, the lower rod 908 will also change its angle accordingly to adapt to the upward movement of the upper rod 907 and maintain the stability of the entire structure. When the bidirectional drive motor 902 rotates to a certain extent and the rotating threaded rod 903 rotates a corresponding number of turns, the connecting rod member 905 moves to a predetermined position, and the upper rod 907 elevates the distribution box to a suitable height. At this time, rainwater is not likely to enter the inside of the distribution box, achieving the purpose of rain prevention. After the distribution box is elevated to the predetermined height, the bidirectional drive motor 902 stops working, the rotating threaded rod 903 no longer rotates, and the relative positions of each rod are fixed, and the distribution box continues to work at the elevated position.

[0023] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
