Abstract
Description
Technical Field
[0001] The utility model relates to a transformer box, in particular to a waterproof transformer box for a workshop. Background Art
[0002] The water treatment workshop of the iron phosphate production line is a sewage treatment workshop that treats the mother liquor after filtration and the primary washing water. The pipes in the workshop are generally made of polypropylene and connected by glue. In the membrane treatment section, the sewage must be concentrated by secondary high-pressure reverse osmosis. The pipes are under high pressure, especially when the pumps are started and stopped, and there is a risk of breakage at the joints. In addition, other similar liquid treatment workshops also have the above-mentioned risk of pipe breakage. Since the workshop is equipped with a transformer box for regulating the power of the equipment, the transformer box usually has a heat dissipation port for heat dissipation. Once the pipe breaks, a large amount of liquid will be sprayed out and it is very easy to enter the transformer box through the heat dissipation port, causing a short circuit problem. Utility Model Content
[0003] Purpose of the utility model: The purpose of the utility model is to provide a transformer box with waterproof function for use in a production workshop.
[0004] Technical solution: The workshop waterproof transformer box described in the utility model includes a transformer box body, and a heat dissipation port is opened on the inner wall of the transformer box body. The heat dissipation port is connected to a ventilation pipe, and the ventilation pipe is at least partially vertically arranged and extends downward. The air inside the transformer box body can be guided to the outside through the heat dissipation port and the ventilation pipe.
[0005] The ventilation duct includes a first ventilation section, a second ventilation section and a third ventilation section connected in sequence from top to bottom; the first ventilation section is connected to the heat dissipation port and is arranged horizontally, the second ventilation section is arranged vertically and extends downward, and the third ventilation section is arranged horizontally and extends to the outside of the transformer box body.
[0006] When a pipeline in a liquid processing workshop such as a ferrous phosphate water processing workshop breaks, the liquid in the pipeline will produce different splashing angles, causing part of the liquid to enter the ventilation pipe. However, by setting a larger height difference between the heat dissipation port and the third ventilation section, the liquid will flow to the bottom surface of the third ventilation section under the influence of gravity. Moreover, since there is a vertical second ventilation section between the heat dissipation port and the third ventilation section, the vertical wall surface of the second ventilation section can block the splashed liquid while using gravity to guide the liquid to the bottom surface of the third ventilation section, thereby reliably preventing the liquid from entering the transformer box.
[0007] A filter screen is installed in the third ventilation section.
[0008] A guide is provided at the connection between the second ventilation section and the third ventilation section. The guide includes an inclined surface facing the outside of the transformer box body. The inclined surface of the guide can guide the liquid accumulated on the bottom surface of the third ventilation section to the outside of the transformer box.
[0009] In order to further enhance the waterproof effect of the transformer box, a waterproof frame is fixed at the end of the third ventilation section. A waterproof baffle is fixedly connected to the top of the transformer box body.
[0010] The heat dissipation opening and the ventilation pipe may be provided on both the left and right sides of the transformer box body to form a better air return flow and improve the heat dissipation efficiency of the transformer box.
[0011] A switch door is arranged on the front side of the transformer box body, and a fixed frame is arranged inside the transformer box body opposite to the switch door. The fixed frame is fixed on the inner wall of the transformer box body, and a plurality of springs are fixed on the surface of the fixed frame facing the switch door. The plurality of springs are connected together to a sealing member and the sealing member is pressed against the gap of the switch door to seal the gap of the switch door and prevent liquid from entering the transformer box through the gap of the switch door.
[0012] The workshop waterproof transformer box also includes a moving part, which includes a frame, a telescopic mechanism and a pulley. The transformer box body is fixedly installed on the frame, the telescopic mechanism is arranged inside the frame, and the pulley is connected to the telescopic mechanism. The telescopic mechanism controls the pulley to extend or retract relative to the frame. When liquid leakage occurs in a liquid processing workshop such as an iron phosphate water treatment workshop, the pulley is unfolded to facilitate the staff to move the transformer box to a safe place and repair and clean the workshop.
[0013] The workshop waterproof transformer box is coated with an anti-corrosion coating at least on the outer surface.
[0014] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. The design of the heat dissipation port and the ventilation pipe can effectively prevent liquid splashing while ensuring the heat dissipation effect, thereby improving the working reliability and safety of the transformer box; 2. A movable part is provided for easy movement and transportation; 3. An anti-corrosion coating is provided on the surface of the transformer box, reducing the risk of corrosion of the transformer box by splashing liquid or humid air in the workshop.
