Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and in particular to a distribution box with a protective function. Background Art

[0002] Distribution boxes are used for switching, controlling, or protecting power systems in power generation, transmission, distribution, energy conversion, and consumption. They are widely used in high and low voltage power grids. In many cases, they are installed outdoors. During installation, a base is built and the distribution box is mounted on the base. Cables pass through the base and enter the distribution box to transmit power to the distribution box.

[0003] However, when the distribution box is installed outdoors for use, due to the complex installation environment, it cannot be guaranteed that the distribution box can be installed in an open and unmanned area. When the distribution box is installed in a location with a lot of people flowing, the problem of the distribution box being hit by a car or intruded by other heavy objects cannot be avoided. The distribution box often has no protective measures, or is simply fenced. Therefore, when invaded, it is very easy for the distribution box to deform or even cause damage to the internal electrical components, causing leakage, power outages or even explosions, resulting in huge economic losses. In addition, due to the frequent occurrence of extreme weather in recent years, the distribution box is flooded in extreme weather, and the internal electrical components are exposed to water, which is also easy to cause leakage, power outages and other problems. Therefore, the use of existing distribution boxes cannot cope with such emergencies. Summary of the Invention

[0028] The beneficial effects of the distribution box with protection function proposed by the present invention are:

[0029] In the present invention, through the setting of the active protection device, during the use of the distribution box, if a car or heavy equipment is invading the distribution box, the support sleeve drives the rotating protection frame to rotate and open, and then the rotating protection frame drives the impact protection plate to resist the invasion of foreign objects, and when the impact protection plate is hit, the buffer frame slides in the rotating protection frame and drives the buffer spring to be stressed, and then under the rebound force of the buffer spring, the impact is buffered, and the distribution box is further protected; in addition, when the side of the distribution box is impacted, it is first protected by the protection frame, and at the same time, when the protection frame is impacted, the support sleeve slides on the rectangular support rod and drives the support spring to be stressed, and then under the rebound force of the support spring, the impact is buffered, and the distribution box is further protected, achieving comprehensive protection of the distribution box, and when the impact protection plate is located on the top side of the distribution box, it can effectively prevent the impact of unexpected situations such as hail or snow on the distribution box, so that the distribution box is fully protected, effectively ensuring the safety of the distribution box.

[0030] Furthermore, in the present invention, by setting up an automatic lifting device, in case of continuous heavy rain or flood weather, when the rainwater in the rain collecting box cannot be discharged from the holes in the rain collecting box in time, the rainwater in the rain collecting box increases rapidly and is forced to move downward, or the floating frame is subjected to the buoyancy of the rising water level, so that the floating frame drives the upper push rod to move, and then the rotating push rod drives the distribution box body to move upward, so that the distribution box body is located at a high place, avoiding the distribution box body from being soaked in water, causing the electrical equipment inside it to be soaked in water, and causing problems such as short circuit, leakage or even explosion, thereby effectively ensuring the safe use of the distribution box body.

[0031] Furthermore, in the present invention, by setting a closed waterproof device, when the distribution box moves upward, the base no longer squeezes the two heat dissipation sealing frames. At this time, under the return force of the two return springs, the heat dissipation sealing frames are pulled downward, and the two heat dissipation windows are closed. At the same time, when the distribution box is separated from the base, the two top opening rods are no longer squeezed. At this time, the two base sealing plates are no longer squeezed, so under the rebound force of the two torsion springs, the two base sealing plates rotate to seal the bottom side of the distribution box; in addition, the cables are clamped by two cable troughs, so that the distribution box is completely closed when the distribution box rises, further preventing water from entering the distribution box, so that the distribution box can continue to maintain power supply in extreme weather.

Figure 7 The embodiment of the present invention provides a distribution box with a protective function, in which pull-back grooves 702 are provided on both sides of the distribution box body 1, and two heat dissipation enclosure frames 701 are slidably installed in the two pull-back grooves 702 respectively; in addition, a pull-back spring 703 is installed on the inner wall of the bottom side of the pull-back groove 702, and the top end of the pull-back spring 703 is installed on the bottom side of the heat dissipation enclosure frame 701. It should be noted that in the embodiment of the present invention, when the distribution box body 1 moves upward, the base 2 no longer squeezes the two heat dissipation enclosure frames 701. At this time, under the pull-back force of the two pull-back springs 703, the heat dissipation enclosure frame 701 is pulled downward, thereby closing the two heat dissipation windows 4.

[0063] Please refer to the instruction manual Figure 5 and Figure 10 , further specifically, in the embodiment of the present invention, a torsion hole 706 is opened on the base cover 704, a torsion shaft 707 is installed in the torsion hole 706, and both ends of the torsion shaft 707 are respectively installed on the inner walls of the two sides of the distribution box body 1;

It should be noted that in the embodiment of the present invention, when the distribution box 1 is installed on the base 2, the base 2 squeezes the two push-open rods 709. At this time, the push-open rods 709 rotate on the torsion shaft 707 against the base cover 704, applying force to the torsion spring 708, thereby allowing the two base cover plates 704 to automatically expand.

[0065] Please continue to refer to the instructions attached Figure 5 and Figure 10 More specifically, in the embodiment of the present invention, two push-open rods 709 are movably mounted on the inner wall of the bottom side of the distribution box 1. The distribution box 1 is pressed on the base 2, driving the two push-open rods 709 to rotate and open against the two base sealing plates 704.

[0066] In addition, a plurality of cable troughs 705 are provided on the sides of the two base sealing plates 704 that are close to each other, and rubber pads for sealing the cables are installed on the inner walls of the cable troughs 705. It should be noted that in the embodiment of the present invention, when the distribution box 1 is separated from the base 2, the two opening rods 709 are no longer squeezed, and the two base sealing plates 704 are no longer squeezed. At this time, under the rebound force of the two torsion springs 708, the two base sealing plates 704 rotate, sealing the bottom side of the distribution box 1. At the same time, the cables are clamped by the two cable troughs 705, so that the distribution box 1 is completely sealed when the distribution box 1 is raised.

[0067] In summary, the working principle of a distribution box with a protection function provided by an embodiment of the present invention is as follows:

[0068] When the distribution box 1 is in use, if a car or heavy equipment is invading the distribution box 1, the compression frame 513 is compressed, so that the compression frame 513 synchronously drives the four expansion racks 510 to move, and the expansion racks 510 slide in the lower pressure groove 511 and squeeze the top pressure spring 512 to bear the force, and the four expansion racks 510 drive the four expansion gears 506 to rotate, and the expansion gear 506 rotates through the rectangular support rod 507 to drive the support sleeve 508 to rotate, so that the support sleeve 508 drives the rotating protective frame 501 to rotate and open, and then the rotating protective frame 501 drives the impact protection plate 503 to resist the invasion of foreign objects, and when the impact protection plate 503 is hit, the buffer frame 502 slides in the rotating protective frame 501 and drives the buffer spring 50 5 is subjected to force, and then the impact is buffered under the rebound force of the buffer spring 505, thereby further protecting the distribution box body 1; in addition, when the side of the distribution box body 1 is impacted, it is first protected by the protective frame 504. At the same time, when the protective frame 504 is impacted, the support sleeve 508 slides on the rectangular support rod 507, and drives the support spring 509 to be subjected to force, and then under the rebound force of the support spring 509, the impact is buffered, thereby further protecting the distribution box body 1, achieving comprehensive protection of the distribution box body 1, and when the impact protection plate 503 is located on the top side of the distribution box body 1, it can effectively prevent the impact of unexpected situations such as hail or snow on the distribution box body 1, so that the distribution box body 1 is fully protected, effectively ensuring the safety of the distribution box body 1;

[0069] Furthermore, in continuous heavy rain or flood weather, when the rainwater in the rain collecting box 615 cannot be discharged from the holes in the rain collecting box 615 in time, the rainwater in the rain collecting box 615 increases rapidly and is forced to move downward, thereby driving the lower pressure rod 612 to move, so that the lower pressure rod 612 drives the rotating push rod 601 to rotate through the driving shaft 610, and at the same time the driving shaft 610 slides in the driving hole 611, or the floating frame 608 is subjected to the buoyancy of the rising water level, so that the floating frame 608 drives the upper push rod 609 to move, and the upper push rod 609 drives the rotating push rod through another driving shaft 610 601 rotates, and at the same time, the push shaft 610 slides in the push hole 611. Therefore, in both cases, the push rod 601 is driven to rotate, and the push rod 601 rotates on a connecting shaft 602. At the same time, the push rod 601 drives the distribution box 1 to move upward through another connecting shaft 602. At the same time, the connecting shaft 602 slides in the lifting chute 614, so that the distribution box 1 is located at a high place, thereby preventing the distribution box 1 from being soaked in water, causing the electrical equipment inside it to be soaked in water, and causing problems such as short circuit, leakage or even explosion, thereby effectively ensuring the safe use of the distribution box 1;

[0070] Furthermore, when the distribution box 1 moves upward, the base 2 no longer squeezes the two heat dissipation sealing frames 701. At this time, under the return force of the two return springs 703, the heat dissipation sealing frame 701 is pulled downward, and the two heat dissipation windows 4 are closed. At the same time, when the distribution box 1 is separated from the base 2, the two top opening rods 709 are no longer squeezed. At this time, the two base sealing plates 704 are no longer squeezed, so under the rebound force of the two torsion springs 708, the two base sealing plates 704 rotate to seal the bottom side of the distribution box 1. In addition, the cables are clamped by the two cable troughs 705, so that the distribution box 1 is completely closed when the distribution box 1 rises, further preventing water from entering the distribution box 1, so that the distribution box 1 can continue to maintain power supply in extreme weather.
