Description

Photovoltaic combiner box Technical Field The utility model relates to electrical equipment, in particular to a photovoltaic combiner box. Background The photovoltaic combiner box is usually installed outdoors, is suitable for a photovoltaic string type power generation system, and is an important power protection part for bearing the string type inverter and the power grid system. In the prior art, when the electric equipment in the photovoltaic combiner box needs to be repaired, the box door of the photovoltaic combiner box is opened, and then detection and repair are carried out. However, as described above, since the photovoltaic junction box is generally installed outdoors, and due to an outdoor environment, the door is often buckled during maintenance, resulting in the necessity of blocking the door by hand or blocking the door's buckling directly with the body by the worker, which makes the worker work distractively. Disclosure of utility model The utility model mainly aims to provide a photovoltaic combiner box, wherein a box door and a box body are convenient to detach, so that a maintenance worker can detach the box door when detecting and maintaining electrical equipment in the photovoltaic combiner box, and the phenomenon that the box door is buckled to influence maintenance operation is avoided. In order to accomplish the above object, the present utility model provides a photovoltaic junction box comprising: The box body, one end of the box body is in an open state, the bottom plate at the bottom of the box body is provided with a strip threading hole, and the bottom plate is provided with an adjusting device capable of controlling the opening of the strip threading hole; The refrigerator door is rotatably buckled on the opening of the refrigerator body, one side of the refrigerator door is hinged with the refrigerator body, the refrigerator door is detachably installed with the refrigerator body, and after the refrigerator door is buckled on the opening, the hinge part is located inside the refrigerator door. Preferably, the adjusting device comprises an adjusting plate, the adjusting plate is provided with adjusting holes which are arranged in an arc shape, the number and the positions of the adjusting holes are matched with the number of the threading holes, and the adjusting plate is in sliding connection with the bottom plate. Further preferably, the two sides of the adjusting plate are provided with strip-shaped holes, the bottom plate is fixedly provided with threaded columns, and the top ends of the threaded columns penetrate out of the strip-shaped holes and are in threaded connection with the nuts. Preferably, the box door is rotatably connected with the box body through a hinge rotating shaft. Further preferably, the hinge shaft is of a telescopic structure. Still further preferably, the hinge shaft comprises an upper bolt, a guide rod, a spring and a lower bolt, wherein the upper bolt and the lower bolt are used for connecting the box door and the box body, the upper bolt and the lower bolt are respectively and slidably connected with two ends of the guide rod, the spring is sleeved on the outer side of the guide rod, and the spring is positioned between the upper bolt and the lower bolt. Still more preferably, the opposite ends of the upper bolt and the lower bolt are respectively provided with a jack, and the guide rod is respectively connected with the upper bolt and the lower bolt in a sliding way through the jacks. The beneficial effects of this use information are: 1. Door detachable design avoids buckling interference The box door and the box body adopt a combined mode of hinging and detachable installation, and the box door can be directly and integrally detached during maintenance. Compared with the traditional fixed type box door, the problem that the box door needs to be blocked and buckled by hands or bodies in the whole process is solved, the interference of automatic closing of the box door to operation is eliminated, workers can concentrate on maintenance, maintenance efficiency is improved, and potential safety hazards are reduced. 2.
