Embodiment 1

[0022] like Figure 1-6 As shown, the sand prevention and pressure relief ring network cabinet includes a cabinet body 1 and four installation rods 2. A connecting rod 3 is respectively arranged on the four corners of the lower end of the cabinet body 1, and one end of the connecting rod 3 is movably connected to the cabinet body 1. , the other end is provided with a collar 301, the installation rod 2 includes a straight rod 201, one end of the straight rod 201 is a tip 202, and the other end is a threaded end 203, and the straight rod 201 is provided with a helical leaf 204 around the tip 202, And near the threaded end 203, a stop ring 205 is provided, the inner diameter of the collar 301 matches the diameter of the straight rod 201, the side of the cabinet body 1 is arranged with semicircular grooves 101 arranged at intervals, between adjacent semicircular grooves 101 Be provided with semicircle protruding line 102, described semicircle groove 101 is parallel with semicircle...

Embodiment 2

[0025] like Figure 7 , Figure 8 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that a hoop 4 is arranged directly above the connection between the connecting rod 3 and the cabinet body 1, the inner diameter of the hoop 4 is matched with the connecting rod 3, and the hoop 4 includes Two half-rings 401 , one of which is fixed on the cabinet body 1 . The hoop is used to fix the connecting rod, mainly because when the ring network cabinet is moving, the connecting rod 3 will swing, which is very obstructive and not conducive to the handling of the device, so it is convenient to set the hoop 4 to fix the connecting rod 3 transport. Both ends of the half-ring 401 are provided with connectors 402 , and the connectors 402 are provided with threaded holes 403 , and the two half-rings 401 are fixed through the connectors 402 . The distance from the hoop 4 to the joint between the connecting rod 3 and the cabinet body 1 is less th...

Abstract

The invention relates to a sand prevention and decompression ring main unit. The sand prevention and decompression ring main unit comprises a unit body and four installation rods; the four corners of the lower end of the unit body is each provided with a connecting rod, one end of each connecting rod is movably connected to the unit body, a lantern ring is arranged at the other end of each connecting rod, each installation rod comprises a straight rod, one end of each straight rod is a tip end, the other end of each straight rod is a threaded end, a spiral blade is arranged at the position, close to the corresponding tip end, of each straight rod in a surrounding mode, the unit body is of a closed structure, a decompression valve is arranged at the upper end of the unit body and connected with the outer end of the unit body through a decompression hole, a protection cover is arranged at an outer port of the decompression hole, a wind deflector is arranged at the top end of the protection cover, and a through hole is formed in the lateral end of the protection cover and located in the lateral side of the wind deflector. The sand prevention and decompression ring main unit has the advantages that the decompression hole of the ring main unit is covered with the protection cover, and the wind deflector is arranged on the protection cover, so that the through hole in the protection cover is perpendicular to the air direction all the time and cannot directly face the wind, blown sand cannot enter the protection cover through the through hole in the protection cover easily, and the possibility that the decompression hole is blocked is avoided.

Description

technical field [0001] The invention relates to a ring network cabinet, in particular to a sand prevention and pressure relief ring network cabinet. Background technique [0002] The outdoor ring network cabinet adopts a vacuum switch as the breaking device, SF6 gas common box insulation, compact structure, small footprint, beautiful appearance, and can coordinate with the surrounding environment. Due to the fully sealed and fully insulated concept, all switch parts in the RVAC ring network cabinet, including all high-voltage live bodies and mechanism parts, are completely sealed in the main box, and are not affected by condensation and external polluted environments; the protection level of the main box can be Up to IP67, equipped with a Cooper waterproof touchable cable head, which can effectively prevent occasional floods in rain-prone areas. [0003] Existing ring network cabinets are generally sealed, and it is generally necessary to set a pressure relief valve for pre...
