Preferably, the widths of the two sets of positioning press plates 104d-3 are the same as the width of the threaded rod 104 b. The threaded rod 104b is sized to fit the threaded opening 102 c. One side of the outer arc-shaped matching plate 102f-1 and one side of the clamping plate 102f-2 are in limit insertion connection with the slot of the inner wall of the left half box 102a through limiting blocks.

The dual-layer power supply assembly 102 also includes a push rod 102k disposed on top thereof.

It should be noted that the arcuate side of the outer arcuate mating plate 102f-1 contacts the tapered plug 104a, so that the outer arcuate mating plate 102f-1 mates with the tapered plug 104a, and the outer arcuate mating plate 102f-1 will displace when the outer arcuate mating plate 102f-1 is pressed by the tapered plug 104 a. The insulation pulling frame 104d-2 includes a pallet disposed at a lower position and a pulling bar disposed above the pallet and connected with the power receiving contact 103c through the moving slot 103b, so that a distance between the power receiving contact 103c and the power supplying contact 102j can be controlled by moving a sliding plate 104d-1 of the insulation pulling frame 104d-2 in the position of the power receiving slot 104c, thereby realizing contact power supply and separation power interruption. The connection of the electrical contact 103c to the device through the line may be performed by using the prior art, and thus will not be described in detail. Both the first battery 102h and the second battery 102i may be of the prior art.

When the power supply module 100 is used, the power supply module 100 is compact in structure, so that workers can directly carry the power supply module to a working area to electrically mount equipment. Two sets of equipment or one set of equipment can be powered on simultaneously according to the requirement, for example, the infrared temperature measurement module 200 and the radar detection module 300 are powered on, so that the two sets of equipment can work according to the control signal of the electronic signal integrated analysis module 400. Only the line at one end of the power contact 103c needs to be connected to the corresponding device. The whole use mode only needs to be used for simultaneously clamping two groups of storage batteries by pulling the push rod 102k and then rotating the threaded rod 104b, then the first power connection frame 104d and the second power connection frame 104e can be used for respectively controlling different storage batteries to be powered on and locking the independent power connection or the double power connection by rotating the threaded rod 104b again, the reliability during use is guaranteed, and the whole use mode is simple and convenient to disassemble and debug.

Then, the storage batteries are required to be fixedly installed, the two groups of storage batteries can be quickly installed and clamped during debugging without complex operation, proper pretightening force is kept, and error electrification can be avoided before the proper pretightening force is achieved. The worker only needs to place the first battery 102h and the second battery 102i between the outer arc-shaped mating plates 102f-1 and the clamping plates 102f-2 of the first fixing member 102f and the second fixing member 102g, respectively, and then pulls the push rod 102k to make the left half box 102a drive the double-layer power supply assembly 102 to be integrally close to the double-layer switch assembly 103 and the clamping and locking assembly 104. At the same time of approaching, the conical plug 104a will simultaneously squeeze the first fixing member 102f and the second fixing member 102g, so that the two sets of outer arc-shaped matching plates 102f-1 drive the power supply to move outwards, and finally stop when the threaded rod 104b moves above the threaded opening 102c, at this time, the first storage battery 102h and the second storage battery 102i are pushed to the maximum distance, the power-on contact 102j and the power-on contact 103c on the side of the storage battery are located on the same plane, the spring 102f-3 is compressed to have a rebound tendency, and a proper clamping force is applied to the storage battery through the clamping plate 102 f-2. Then, only the threaded rod 104b needs to be rotated, so that the bottom of the threaded rod 104b is screwed out of the bottom of the conical plug 104a and into the threaded opening 102c, and the relative positions of the double-layer power supply assembly 102 and the clamping and locking assembly 104 are locked, so that the stability of clamping two groups of storage batteries is ensured.

When two groups of equipment are required to be powered on, only the first power receiving frame 104d and the second power receiving frame 104e are required to be pulled, the sliding plate 104d-1 moves in the power receiving groove 104c and the pushing groove 102d, the pulling rod of the insulation pulling frame 104d-2 moves in the moving groove 103b, the power receiving contact 103c is contacted with the power-on contact 102j for power on, at the moment, the positioning pressing plate 104d-3 at one side of the bottom of the sliding plate 104d-1 moves to the position below the threaded opening 102c, and only the threaded rod 104b is required to be rotated to enable the threaded rod 104b to continuously rotate downwards to tightly push the positioning pressing plates 104d-3 at the lower layers of the first power receiving frame 104d and the second power receiving frame 104e, and the bottom surface of the positioning pressing plate 104d-3 is contacted with the hollow shell 101 and tightly pushed by the threaded rod 104b, so that the first power receiving frame 104d and the second power receiving frame 104e cannot move, and the stability in the communication is ensured. When only one group of equipment is powered on, the threaded rod 104b is screwed out upwards, but the connection with the threaded port 102c is maintained, then the group of electric racks 104d is pulled to the initial position, and then the threaded rod 104b is screwed downwards to tightly prop up, so that the operation is simple, flexible and convenient.

When the storage battery is dismounted or replaced, the electric connection state and the clamping state can be simultaneously unlocked only by screwing the threaded rod 104b out of the threaded hole 102c, and then the double-layer power supply assembly 102 is pulled to the initial position through the push rod 102k to replace the storage battery.

In summary, the clamping and locking assembly can clamp two groups of storage batteries of the double-layer power supply assembly to proper force by pushing the double-layer power supply assembly, and the power connection position of the storage batteries is moved to a correct power connection position after clamping, so that false power on is avoided, and the dismounting speed is improved; the two groups of storage batteries after clamping and fixing can be stably locked only through one group of bolts, and the storage batteries when being connected are locked through the bolts after the switch of different storage batteries is flexibly adjusted so as to ensure the stability when the power is connected, thereby ensuring the reliability when the storage batteries are used and improving the replacement efficiency.

It is important to note that the construction and arrangement of the application as shown in the various exemplary embodiments is illustrative only.
