[0033] The foregoing and other technical contents, features and effects of the present application will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. Figures 1-5 The structural contents mentioned in the following embodiments are all referred to the drawings.

[0034] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] The present embodiment discloses an electrically separated camera power supply device, which has the structure as shown in the figure. Figures 1-5 The device comprises two independent units, i.e. a battery module 1 and an inverter module 2.

[0036] The battery module 1 is composed of a plurality of battery packs 11, each of which is provided at the top with a telescopic spring pin assembly 3 and at the bottom with a battery positioning hole 12.

[0037] The spring pin assembly 3 comprises: an elastic member 31 in the form of a compression spring, which is accommodated in a cylindrical sliding hole at the top of the battery pack 11

[0038] A positioning block 32 in the form of a cylinder, which is axially movable along the sliding hole in linkage with the elastic member 31

[0039] A limiting member 33 in the form of a ring nut, which is threadedly connected to the top end of the sliding hole and limits the maximum extension length of the positioning block 32 by adjusting the position of the nut.

[0040] The inverter module 2 comprises:

[0041] An inverter body 21, which is internally integrated with a DC / AC conversion circuit

[0042] A detachable connecting piece 22 in the form of an L-shaped aluminum alloy bracket or a handle-shaped connecting piece, which is provided at the bottom with an inverter positioning hole 23 cooperating with the spring pin assembly 3

[0043] An operation panel 24, which is integrated with a 7-inch LCD display screen 25, two AC output ports 26 and an air switch 27

[0044] A protective cover 28, which is connected to the operation panel 24 through a stainless steel hinge and can cover the air switch 27 and be fixed through an M4 locking screw 29

[0045] Connection structure: the battery module 1 and the inverter module 2 are vertically stacked and positioned through the nesting of four sets of spring pin assemblies 3 and positioning holes. The battery pack 11 and the inverter body 21 are electrically connected through a connection line with a mistaken insertion prevention interface. The interface adopts an aviation plug structure and is provided with a mistaken insertion prevention boss and groove cooperation structure.

[0046] In this embodiment 2, the embodiment 1 is improved,
