The off-grid valve chamber is a valve chamber cabin which is not connected with commercial power and is used for various electrical equipment in the cabin by utilizing photovoltaic power generation. The valve chamber is a special prefabricated cabin of petrochemical oil pipeline, and is characterized by long pipeline route, remote place and small load, and the power supply nearby the working condition environment is less, so that the power consumption of the valve chamber is difficult. Therefore, the off-grid valve chamber has more application in the petrochemical field.

In order to solve the problem that the installation angle of the photovoltaic panel relative to the valve chamber cannot be adjusted, the direct solar angles in different areas are different, the utilization rate of the photovoltaic panel is low, and the generated energy of the photovoltaic panel with the same surface area is low, in the embodiment, the photovoltaic part 100 is designed to be of a structure with an adjustable angle relative to the off-grid valve chamber.

In this embodiment, as shown in fig. 8, 9, 10 and 11, the connection part includes a first connection assembly 510 and a second connection assembly 520.

Wherein the first support bar 410 is hinged to the door panel assembly 300 through the first connection assembly 510.

The second support bar 420 is hinged with the photovoltaic part 100.

The photovoltaic part 100 is rotatably connected with the cap assembly 200 through the second connection assembly 520.

Through the hinge connection of the first support rod 410 and the door panel assembly 300, the hinge connection of the second support rod 420 and the photovoltaic part 100, and the telescopic connection of the first support rod 410 and the second support rod 420, the angle of the photovoltaic part relative to the off-grid valve chamber is adjustable, so that the illumination angles of different seasons in different areas are matched. Thus, the photovoltaic part 100 maintains a proper angle with respect to the illumination direction, thereby improving the utilization rate of illumination. The power generation capacity of the photovoltaic panels with the same surface area is improved.

In this embodiment, the photovoltaic section 100 and support telescoping assembly 400 are also provided, as the housing is generally sized with reference to the maximum shipping size, whereas off-grid housings are more conventional.

The photovoltaic part 100 and the support telescopic assembly 400 are installed on the valve chamber and occupy larger space, so that the transportation convenience of the valve chamber is not affected, meanwhile, the internal space of the valve chamber is unchanged, the photovoltaic part 100 and the support telescopic assembly 400 are designed to be of a structure which can be detached from the net-shaped valve chamber relatively, and the photovoltaic part 100 and the support telescopic assembly 400 are detached from the valve chamber during transportation.

In order to achieve the above connection function, as shown in fig. 11, the first connection assembly 510 includes a flange 511 and a U-shaped connection member 512.

The first end of the second support bar 420 is hinged to the photovoltaic part 100, thereby enabling a rotatable connection of the second support bar 420 to the photovoltaic part 100.

In order to realize the scalability of the first support rod 410 and the second support rod 420, at least two elongated holes 411 are formed at the second end of the first support rod 410, and the directions of the at least two elongated holes 411 are along the length direction of the first support rod 410.

A plurality of telescopic connection holes are formed in the second end of the second support rod 420, and the telescopic connection holes are formed along the length direction of the second support rod 420.

Specifically, the distance between two adjacent expansion connecting holes is equal to the distance between two adjacent elongated holes 411.

According to the requirements of the relative position relationship between the first support rod 410 and the second support rod 420, different telescopic connecting holes are adjusted to be opposite to the strip holes 411, and the fastener passes through the telescopic connecting holes and the strip holes 411 once, so that the relative position relationship between the first support rod 410 and the second support rod 420 is determined.

In order to prevent the first support pole 410 and the second support pole 420 from rotating relative to each other, at least two fasteners are required to pass through the different elongated holes 411 and the telescopic connection holes in sequence.

As shown in fig. 1, 2, 8 and 9, connecting holes are formed at positions corresponding to the rotating shaft assembly 521 on both sides of the bottom plate 130.

The rotating shaft assembly 521 can be inserted into the connecting hole, and the connecting hole can rotate relative to the rotating shaft assembly 521.

And, the pivot subassembly 521 can remove from the connecting hole, realizes the relative dismantlement between the two.

In this embodiment, the spindle assembly 521 includes an outer shaft 522, an inner shaft 523, and a locating pin 524.

A first positioning through hole is formed in the first end of the outer shaft 522 in a radial direction thereof.

A second positioning through hole is provided in the first end of the inner shaft 523 in a radial direction thereof.

After the first end of the outer shaft 522 is sleeved outside the first end of the inner shaft 523, the first positioning through holes correspond to the second positioning through holes in position, and the positioning pins 524 pass through the first positioning through holes and the second positioning through holes.

Specifically, the positioning pin 524 is in interference fit with the first positioning through hole and the second positioning through hole.

Meanwhile, if the photovoltaic unit 100 is required to be detached from the top cover assembly 200, the positioning pins 524 may be pulled out from the first positioning through holes and the second positioning through holes.

Since the outer shaft 522 is sleeved outside the inner shaft 523 and the outer shaft 522 is detachably connected to the connection hole, the outer shaft 522 can be moved outwards from the connection hole and slid along the inner shaft 523 to abut against the top cover assembly 200, thereby completing the disassembly of the photovoltaic part 100 relative to the top cover assembly 200.

Thereby forming a polyurethane foam and rock wool board double layer insulation of the door panel assembly 300.

And because the base foaming heat preservation and the base rock wool heat preservation are in the cavity of the double-layer door plate 330, the heat bridge between different materials is blocked, the design without the heat bridge is formed, and the heat preservation performance is further improved.

To ensure the useful life of the valve housing, the outer surface of the double door panel 330 is coated with an anti-corrosive layer.
