Abstract
The utility model discloses a waterproof structure of a photovoltaic combiner box, which comprises an upper housing and a lower housing of the combiner box. The upper housing and the lower housing each have one side connected through hinges and the other side fixedly connected through door locks. Sealants are arranged on the contact gap part of the upper housing and the lower housing. The flanging part of the lower housing adopts a three-folding-edge structure. By adopting hinges and door locks to connect the upper housing and the lower housing, arranging sealants on the middle gap part, and further using novel sheet metal structures, the waterproof structure of the photovoltaic combiner box takes waterproof measures on the upper housing and the lower housing, effectively increases the airtightness and achieves a high protection level. An adverse influence on other performances of the combiner box due to a low protection level is thus effectively prevented.
Description
Technical field
The utility model relates to grid-connected collector-shoe gear technical field, relates in particular to a kind of waterproof construction of photovoltaic header box.
Background technology
Entered since the new century, the photovoltaic industry has become one of world today's new industry of greatest concern.Photovoltaic generation is to utilize solar energy and semi-conductor electronic device to absorb the solar radiation energy effectively, photoelectricity does not need fuel, no gas discharging, belong to " green " industry, have that pollution-free, safety, long-life, maintenance are simple, resource characteristics such as never exhaustion and resource distribution be extensive, be considered to most important new forms of energy of 21 century, can be widely used in fields such as space flight, communication, the energy, agricultural, office facility, traffic and private residence.Photovoltaic plant mainly is made up of photovoltaic cell arrays, header box, low-voltage direct cabinet, inversion cabinet, AC low-tension cabinet, step-up transformer etc., and the high-voltage alternating of Chan Shenging directly is connected to the grid at last.
Header box as one of part of photovoltaic plant, it is many often to have quantity in use in the power station, characteristics such as layout is intensive, it is better outdoor that these characteristics have determined that it is installed in, this has just proposed higher requirement to the degree of protection of header box, most header boxs are because of its seal problem, and cause its usability etc. to be affected.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of seal strong, degree of protection height, the waterproof construction of the photovoltaic header box of lifting serviceability.
The utility model is achieved through the following technical solutions:
A kind of waterproof construction of photovoltaic header box, the upper shell and the lower house that comprise header box, one side of described upper shell and lower house is connected through the hinge, and opposite side is fixedly connected by door lock, safeguards, overhauls or repair convenient and simple, good leak tightness, because upper and lower casing is sheet metal component, and is very big by the mechanical seal difficulty, the sticking fluid sealant that is covered with in position, the contacted gap of upper and lower casing, reached good sealing effectiveness, the flanging place of described lower house adopts three road bending edges structures.
Have through hole on the minimum face of described upper shell, be convenient to draining, invade if any ponding, can carry over sidewall and discharge by this hole.
The three road bending edges structures at the flanging place of described lower house are: the first road bending edges is horizontal sides, the second road bending edges is vertical edge, the 3rd road bending edges is the miter angle limit, wherein the first and second road bending edges form one " rhone ", when water comes, just discharge because the pressure area of wedge angle is big, and pressure is big by this rhone, the 3rd road bending edges well compresses fluid sealant.
The utility model has the advantages that: the utility model upper and lower casing adopts to be hinged and adds the mode of door lock, the sticking fluid sealant that is covered with in intermediate space place, and used new sheet metal structural, increased waterproof measure at last lower house, improved air-tightness effectively, reached high anti-expansion grade, the harmful effect of having avoided effectively producing because of anti-level grade that its performance is brought.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 connects figure for the upper and lower casing fluid sealant.
Fig. 3 is the lower house sheet metal structural.
Fig. 4 is upper shell draining hole pattern.
Embodiment
As shown in Figure 1, a kind of waterproof construction of photovoltaic header box, the upper shell 1 and the lower house 2 that comprise header box, one side of described upper shell 1 and lower house 2 is connected by hinge 3, opposite side is fixedly connected by door lock 4, safeguard, overhaul or repair convenient and simple, good leak tightness, because upper and lower casing 1,2 is sheet metal component, very big by the mechanical seal difficulty, upper and lower casing 1, position, 2 contacted gap are glued and are covered with fluid sealant 5, have reached good sealing effectiveness, as shown in Figure 2, the flanging place of described lower house 2 adopts three road bending edges structures.
Have through hole 9 on the minimum face of described upper shell 1, as shown in Figure 4, be convenient to draining, invade if any ponding, can carry over sidewall and discharge by this hole.
The three road bending edges structures at the flanging place of described lower house 2 are: as shown in Figure 3, the first road bending edges 6 is horizontal sides, the second road bending edges 7 is vertical edge, the 3rd road bending edges 8 is the miter angle limit, wherein the first and second road bending edges 6,7 form one " rhone ", when water comes, just discharge by this rhone because the pressure area of wedge angle is big, pressure is big, and the 3rd road bending edges 8 well compresses fluid sealant 5.
Claims (3)
1. the waterproof construction of a photovoltaic header box, the upper shell and the lower house that comprise header box, it is characterized in that: a side of described upper shell and lower house is connected through the hinge, opposite side is fixedly connected by door lock, position, the contacted gap of upper and lower casing is sticking to be covered with fluid sealant, and the flanging place of described lower house adopts three road bending edges structures.
2. the waterproof construction of photovoltaic header box according to claim 1 is characterized in that: have through hole on the minimum face of described upper shell.
