Problems solved by technology

[0002] A power distribution device needs to be installed at the crossing. The power distribution device carries the power distribution system and the PLC logic controller, supplies power to the signal lights and the PLC logic controller through the power distribution system, and then controls the lighting sequence and point of the signal lights through the PLC logic control. The working temperature range of PLC is generally 0°C to 55°C for horizontal installation and 0°C to 45°C for vertical installation. PLC overheating damage

Embodiment 1

[0028] See Figure 1 to Figure 4 As shown, it includes a cabinet body 1. The cabinet body adopts cold-rolled plate SPCC, and a bracket plate 2 is screwed inside the cabinet body 1, and embedding grooves 201 are processed at the top left and right sides of the bracket plate 2. A bracket 3 is installed between the two embedded slots 201. The height of the bracket 3 is 20 cm. A fan 4 is installed in the middle of the bracket 3 to exhaust air. The fan 4 adopts the power distribution system to supply power. The support plate 2 has an air outlet groove 202 corresponding to the fan 4 on its surface. The left and right sides of the cabinet 1 are provided with first air outlet grooves 101 for discharging hot air outward. The end of 101 away from the inside of the cabinet 1 is arranged obliquely downwards, and side strips 5 are welded on the inner left and right sides of the cabinet 1, and the surface of the side strip 5 is evenly distributed with installation grooves 501, between the si...

Embodiment 2

[0031] See Figure 5 As shown, a support plate 121 is screwed to a position near the inner top of the cabinet body 1, and a filling gap is formed between the upper part of the support plate 121 and the inner top of the cabinet body 1, and the filling gap position is filled with heat insulation Cotton 131, insulation cotton also uses glass fiber cotton, the height of the filling gap is 20mm, by filling insulation cotton, heat insulation can be formed on the top of the cabinet. Between 11 and 14 o'clock every day, the temperature is higher when the sun is Therefore, the insulation cotton can reduce the introduction of heat at the top, thereby achieving the effect of heat insulation. At the same time, the top of the cabinet is subject to rain corrosion all the year round, so the probability of damage after corrosion will increase. Cotton can also play a temporary waterproofing effect, and water cannot penetrate through the support plate 121.

Embodiment 3

[0033] See Image 6 As shown, a wind baffle 131 is welded at the position of the inner rear end surface of the cabinet 1, and a ventilation gap is formed between the left and right sides of the wind baffle 131 and the inner side wall of the cabinet 1, and the cold air blown upward from the first fan passes through The wind baffle passes through the gap to both sides and then acts upward on the cooled power distribution system. By setting the wind baffle, the cold air can be conveyed upward from both sides, and the hot air can be discharged through the upper fan. Lower the internal temperature.

Abstract

The invention discloses a municipal power distribution device. A bracket plate is screwed to the inside of the cabinet body, Embedding grooves are machined at left and right positions on the top of the bracket plate, Between that two embed grooves is instal a bracket, the height of the bracket is 15cm -25cm, An upward exhaust fan is mounted at a central position of the bracket, The fan adopts thecentralized power supply of the distribution system, and a corresponding air outlet groove for the fan is arranged on the plate surface of the support plate, and a first air outlet groove for discharging the hot air outward is arranged on the left and right sides of the cabinet body, and the first air outlet groove is inclined downward away from the inner end of the cabinet body; The device can effectively increase heat dissipation performance.

Description

Technical field [0001] The invention relates to a municipal power distribution device. Background technique [0002] A power distribution device needs to be installed at the crossing position, which carries the power distribution system and PLC logic controller through the power distribution device, supplies power to the signal lights and PLC logic controller through the power distribution system, and then controls the lighting sequence and point of the signal lights through the PLC logic control Bright time, and the PLC's operating temperature range: generally horizontal installation 0℃ to 55℃, vertical installation 0℃ to 45℃, but in summer, the temperature of the road surface is between 55~75℃, which will easily lead to overheating inside the power distribution device. The PLC is overheated and damaged. [0003] Based on the above problems, it is necessary to provide a municipal power distribution device that can effectively increase heat dissipation performance. Summary of the...
