Its production process is to first design the content (which can be text and graphics) using graphic design software or special lettering software, punch holes in the aluminum-plastic board according to the pre-designed stroke pattern, and then install the light-emitting diodes in the holes in series, and use the DC pulse flashing provided by the AOTE electronic light box controller to achieve a variety of changing effects such as flashing, flowing, rolling, and superimposing of text or patterns.

[0003] Train signals are used to guide passengers and require eye-catching LED light boxes. However, train signal lights are often located next to the tracks where trains travel, so there is a lot of dust. The prior art uses filters to prevent dust, but the dust prevention effect is poor, resulting in a large amount of dust accumulating inside the LED light box, causing a short circuit in the line, causing the LED light box to fail to work properly and be easily damaged. Therefore, an LED light box for train signals is proposed to solve the above problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an LED light box for train signals, which has the advantages of good dust prevention effect and increased service life, and solves the problem that train signal lights are often located next to the tracks where trains travel, so there is a lot of dust. The prior art uses filters to prevent dust, but the dust prevention effect is poor, resulting in a large amount of dust accumulation inside the LED light box, causing a short circuit in the line, causing the LED light box to fail to work normally and be easily damaged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED light box for train signals, comprising a lamp holder, a mounting frame is fixedly installed at the bottom of the lamp holder, a lamp pole is fixedly installed at the top of the lamp holder, a mounting plate is fixedly installed at the front of the lamp pole, a light box is fixedly installed at the top of the lamp pole, and a dustproof mechanism is fixedly installed at the bottom of the light box;

[0006] The dust-proof mechanism includes a dust-proof box, a dust-proof box is fixedly installed on the bottom of the light box, a heat dissipation net is fixedly installed on the left and right sides of the bottom of the dust-proof box, a partition is fixedly installed between the two heat dissipation nets, a processing box is fixedly installed on the left and right sides of the inner wall of the dust-proof box, a fan is fixedly installed on the top of the partition, a filter is fixedly installed on the top of the processing box, a dust collecting roller is rotatably installed inside the processing box, a liquid storage box is fixedly installed on the left and right sides of the inner wall of the dust-proof box, a partition is fixedly installed on the top of the liquid storage box, the outer surface of the dust collecting roller is covered with electrostatic dust removal paper, and a driving motor is fixedly installed at the end of the dust collecting roller.

[0007] Furthermore, the mounting frame is fixedly connected to the lamp holder by bolts, and the lamp pole is fixedly installed at the center position of the bottom of the light box.

[0008] Furthermore, the partition is located at the center of the dustproof box, and the top end of the lamp pole is fixedly connected to the partition.

[0009] Furthermore, the fan is located at the center of two processing boxes, and the processing boxes are located above the heat dissipation net.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The LED light box for train signals is provided with a dustproof mechanism. When the LED light box is working, heat will be generated. At this time, the LED light box needs to be heat-dissipated. Heat dissipation requires external wind force to complete. The wind enters the dust removal box from the heat dissipation net. The wind force generated by the rotation of the fan sends the external wind into the two processing boxes. The dust collecting roller inside the processing box is driven by the driving motor to rotate, and the dust carried in the wind is attached by the electrostatic dust removal paper on the outer surface. The wind enters the interior of the light box for heat dissipation after being filtered by the filter net. When the dust collecting roller rotates, the dust will also fall into the interior of the liquid storage box and float on the surface of the pure water to collect the dust. The pure water in the liquid storage box can be replaced regularly. The wind used for heat dissipation can be effectively purified before use, so as to avoid dust entering the LED light box and causing a short circuit, thereby effectively improving the service life of the LED light box.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, an LED light box for train signal includes a lamp holder 1, a mounting frame 2 is fixedly installed at the bottom of the lamp holder 1, a lamp pole 3 is fixedly installed at the top of the lamp holder 1, a mounting plate 4 is fixedly installed at the front of the lamp pole 3, a light box 5 is fixedly installed at the top of the lamp pole 3, and a dustproof mechanism 6 is fixedly installed at the bottom of the light box 5;

[0022] The dustproof mechanism 6 includes a dustproof box 601, which is fixedly installed on the bottom of the light box 5, and heat dissipation nets 602 are fixedly installed on the left and right sides of the bottom of the dustproof box 601, and a partition 603 is fixedly installed between the two heat dissipation nets 602. The left and right sides of the inner wall of the dustproof box 601 are fixedly installed with processing boxes 604, and the top of the partition 603 is fixedly installed with a fan 605. The top of the processing box 604 is fixedly installed with a filter net 606. The inside of the processing box 604 is rotatably installed with a dust collecting roller 607, and the left and right sides of the inner wall of the dustproof box 601 are fixedly installed with a liquid storage box 608. The top of the liquid storage box 608 is fixedly installed with a partition net 609. The outer surface of the dust collecting roller 607 is provided with an electrostatic dust removal paper 610. The electrostatic dust removal paper 610 is a fiber fabric made of chemical materials such as polyester and polypropylene. Its surface is treated with static charge and can absorb particulate matter in the air. When the particles in the air come into contact with the electrostatic dust removal paper with static charge, they will be strongly adsorbed on it and collected with the flow of air. A driving motor 611 is fixedly installed at the end of the dust collecting roller 607.

[0023] When implementing, follow these steps:

[0024] 1) First, the fan 605 is started to rotate to generate wind force to send the external wind into the inside of the two processing boxes 604, and the dust collecting roller 607 inside the processing box 604 is driven by the driving motor 611 to rotate;

[0025] 2) The dust in the wind is then attached by the electrostatic dust removal paper 610 on the outer surface, and the wind is filtered by the filter 606 and then enters the interior of the light box 5 for heat dissipation;

[0026] 3) When the dust collecting roller 607 rotates, the dust will fall into the liquid storage box 608 and float on the surface of the pure water to collect the dust;

[0027] 4) Finally, the purified water in the liquid storage box 608 can be replaced regularly.

[0028] To sum up, the LED light box for train signals can effectively purify the air used for heat dissipation before use, thereby preventing dust from entering the LED light box and causing a short circuit, effectively improving the service life of the LED light box, and solving the problem that train signal lights are often next to the tracks where trains travel, so there will be a lot of dust. The existing technology uses filters to prevent dust, but the dust prevention effect is not good, resulting in a large amount of dust accumulation inside the LED light box, causing a short circuit, causing the LED light box to fail to work normally and be easily damaged.
