Abstract
The invention discloses a snow-preventing, ice-preventing and freezing-preventing power distribution box. The power distribution box comprises a housing with an opening. The housing is internally provided with a housing inner chamber for mounting components. A housing door is mounted on the opening of the housing in an openable manner. The external surface of the housing door is provided with a handle. The housing comprises a top panel, a bottom panel and a back panel. An arc-shaped top cover covers the top of the housing. The top panel, the bottom panel and the back panel are hollow boards. The chambers in the top panel, the bottom panel and the back panel are respectively provided with a plurality of electric heating tubes. The inner surfaces of the top panel, the bottom panel and the back panel are respectively provided with a plurality of through holes for communicating the chambers with the housing inner chamber. A heat insulation cotton layer covers the inner surface of the housing door. The snow-preventing, ice-preventing and freezing-preventing power distribution box can prevent snow accumulation, housing crack caused by freezing, and low-temperature faults in a severe cold area.
Description
Technical field
The present invention relates to a kind of anti-icing antifreeze distribution box of snow defence.
Background technology
Distribution box is a kind of power distribution equipment for plaing a part of to distribute electric energy in supply line, and it applies quite varied.Distribution box is when severe cold area uses, it is easy to cause failure because temperature is too low；And the easily bursting by freezing due to low temperature of the casing of distribution box；And when snowing heavily, the easy accumulated snow in top of distribution box, accumulated snow will make distribution box compressive deformation.
The content of the invention
The technical problem to be solved is to provide a kind of anti-icing antifreeze distribution box of snow defence, and it can avoid accumulated snow, casing bursting by freezing and low temperature failure when severe cold area uses.
To solve above-mentioned technical problem, the anti-icing antifreeze distribution box of snow defence that the present invention is provided, it includes a casing with opening, it is the cabinets cavity for mounting related components in casing, on the opening of casing can folding chamber door is installed, handle is provided with the outer surface of chamber door, casing includes a top panel, a bottom panel and a rear board, the overhead guard of an arch is coated with the top of described casing；
Described top panel, bottom panel and rear board are hollow plate body, be provided with several electrothermal tubes in cavity in top panel, bottom panel and rear board, top panel, bottom panel with several through holes for connecting cavity and cabinets cavity are provided with the inner surface of rear board；A heat insulation foam layer is coated with the inner surface of chamber door.
Preferably, being provided with rubber weather strip on the upper surface and lower surface of described chamber door.
Preferably, the bottom of described casing is provided with roller.
Preferably, described overhead guard is installed in the top of casing.
After above structure, the present invention compared with prior art, has the following advantages that：
When snowing, the overhead guard due to being provided with arch at the top of casing, snow is fallen on overhead guard, and so, when the accumulated snow on overhead guard, accumulated snow can be slipped on ground along overhead guard, can thus avoid the accumulated snow on casing；And when temperature is too low, electrothermal tube energization work, electrothermal tube can be made to heat to top panel, bottom panel and side panel, to prevent top panel, bottom panel and side panel bursting by freezing；And the heat that electrothermal tube is produced can be transmitted to cabinets cavity by through hole, to prevent the electrical equipment being arranged in cabinets cavity from damaging due to low temperature；And heat insulation foam can reduce outdoor cold and be transmitted to cabinets cavity by chamber door, further prevent the temperature in cabinets cavity too low.So, the distribution box can avoid the accumulated snow on casing and make casing compressive deformation, can also avoid casing bursting by freezing, and the electrical equipment in casing can also be avoided to break down due to low temperature.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the anti-icing antifreeze distribution box of snow defence of the present invention includes a casing with opening, it is the cabinets cavity 6 for mounting related components in casing, on the opening of casing can folding chamber door 1 is installed, handle 101 is provided with the outer surface of chamber door 1, casing includes a top panel 2, a bottom panel 3 and a rear board 4, the overhead guard 9 of an arch is coated with the top of described casing, that is to say, that overhead guard 9 arches upward upwards.
Described top panel 2, bottom panel 3 and rear board 4 are hollow plate body, be provided with several electrothermal tubes 5 in cavity 10 in top panel 2, bottom panel 3 and rear board 4, top panel 2, bottom panel 3 with several through holes 7 for connecting cavity 10 and cabinets cavity 6 are provided with the inner surface of rear board 4；A heat insulation foam layer 102 is coated with the inner surface of chamber door 1.
Rubber weather strip 103 is provided with the upper surface and lower surface of described chamber door 1, so so that the sealing effectiveness of chamber door 1 more preferably, can more avoid outdoor cold from flowing into cabinets cavity 6.
The bottom of described casing is provided with roller 8, and roller 8 has four and rectangular distribution, and so, the anti-icing antifreeze distribution box of the snow defence can be moved by roller 8, and movement is more convenient.
Described overhead guard 9 is installed in the top of casing, it is preferred that overhead guard 9 is weldingly fixed on the top of casing, can so avoid overhead guard 9 from dropping from casing top.
Below only just present invention application preferably example is made that explanation, but is not to be construed as limiting the scope of the invention, and the structure of the present invention can have other to change, and be not limited to said structure.In a word, the various change made in the protection domain of all independent claims in the present invention is within the scope of the present invention.
