Embodiment 2

Please refer to Figures 1 to 8. This embodiment provides a technical solution based on the first embodiment:

The transmission mechanism includes a cavity 17 arranged in the inner cylinder 9, a butt plate 18 is fixed on the upper wall of the power strip 12, the butt plate 18 is in the cavity 17, and a first slide groove 19 is provided on the side wall of the cavity 17, a first slider 20 slides in the first slide groove 19, the first slider 20 and the side wall of the sliding plate 11 are fixed to each other, an elastic telescopic rod 21 is rotatably arranged on the lower wall of the first slider 20, a transmission rod 22 is rotatably arranged at the lower end of the elastic telescopic rod 21, the butt plate 18 and the transmission rod 22 are rotatably connected, and the angle between the elastic telescopic rod 21 and the transmission rod 22 is an obtuse angle.

It should be noted that when the first slider 20 moves downward, it first pushes the abutment plate 18 to move, so that the abutment plate 18 drives the two power connection plates 12 to move relative to each other until they contact the power connection point at the lower end of the power connection pole 3. At this time, the controller 7 can connect and detect the energy storage device 2 to detect the amount of electricity stored and the voltage at both ends, thereby ensuring efficient detection of the energy storage device 2. After that, as the sliding plate 11 continues to move downward, the elastic telescopic rod 21 begins to be compressed, effectively preventing the sliding plate 11 from being stuck and unable to move further downward after the first slider 20 moves downward to a certain extent.

In an optional embodiment: the movable mechanism includes a second slide groove 26 arranged on the lower wall of the horizontal plate 24, a second slider 27 slides in the second slide groove 26, the second slider 27 is fixedly connected to the upper wall of the connecting plate 16, and a slide rail 14 is opened on the lower wall of the detection cavity 23, and the slide rail 14 and the two connecting columns 15 correspond to each other.

It should be noted that the movement process of the connecting tube 6 is structurally supported so that when the connecting plate 16 moves, the second slide groove 26 and the second slider 27 cooperate to ensure smooth movement of the connecting plate 16 and avoid separation between the connecting plate 16 and the cross plate 24.

In an optional embodiment: the mobile control mechanism includes a first gear 29 fixedly arranged on the side wall of the corresponding control rod 28, and a second gear 30 is meshed and rotatably arranged on the side wall of the first gear 29. A reciprocating screw 31 is also rotatably arranged in the detection chamber 23. The reciprocating screw 31 passes through the connecting plate 16 on the same side, and the connecting plate 16 and the reciprocating screw 31 match each other. A gear box 32 is arranged at one end of the reciprocating screw 31, and the reciprocating screw 31 and the second gear 30 are connected by transmission through the gear box 32. A connecting plate is rotatably arranged on the other end of the reciprocating screw 31, and the connecting plate is fixedly connected to the inner wall of the detection chamber 23 to support the rotation of the reciprocating screw 31 and ensure the normal operation of the device.

It should be noted that by rotating the control rod 28, the first gear 29 is driven to rotate, and the rotation of the first gear 29 also drives the second gear 30 to rotate, so that the reciprocating screw 31 is rotated, and the connecting plate 16 matching the reciprocating screw 31 moves accordingly. Under the mutual cooperation of the second slide groove 26 and the second slider 27, the other connecting tube 6 is moved, so that the device can be suitable for energy storage devices 2 of different specifications and sizes, and can quickly detect power poles 3 with different spacings.

A method for using a power storage device power storage detection device comprises the following steps:

S1: docking the detection device with the power connection post 3: docking the fixed connection cylinder 6 with the corresponding power connection post 3 according to the positive and negative poles, and then docking the other connection cylinder 6 with the other power connection post 3 by moving the other connection cylinder 6;

S2: Connection process: Press the control lever 28 to drive the power connection plate 12 to clamp the lower wall of the power connection column 3, and clean the side edge of the connection column 3 with cleaning mud;

S3: Detection process: the controller 7 is powered on to detect the energy storage device 2. The cleaning mud then acts as an insulator at the connection between the electric pole 3 and the electric connection sheet 12.

S4: during the recovery process, the control rod 28 is released, the control rod 28 rebounds, and the cleaning mud is taken out and replaced for next use.

Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

When it is necessary to test the power energy storage device, the test of energy storage device 2 is as follows:

First, one of the connecting tubes 6 and the power pole 3 is brought close to each other, and the power pole 3 and the insulating tube 4 are surrounded by the inner tube 9. At this time, the two control rods 28 are pressed down by pulling the controller 7. When the control rods 28 are pressed down, the cross plate 24 is driven to push the connecting column 15 and the connecting plate 16 downward. When the connecting column 15 moves downward, the sliding plate 11 is pushed downward. At this time, the cleaning mud between the connecting tube 6 and the inner tube 9 is squeezed, and is tightly fitted with the peripheral side wall of the power pole 3, and is squeezed out through the through groove 13. At the same time, when the sliding plate 11 moves downward, it drives the first sliding block 20 to move downward synchronously. Due to the large elastic resistance of the elastic telescopic rod 21 itself, when the first sliding block 20 moves downward, it first pushes the abutment plate 18 to move, so that the abutment plate 18 drives the two power connection pieces 12 to move relative to each other until they are aligned with the power pole. The lower end of the column 3 is in contact with the power connection, and the controller 7 can connect and detect the energy storage device 2 to detect the amount of electricity stored and the voltage at both ends, so as to ensure efficient detection of the energy storage device 2. Then, as the sliding plate 11 continues to move downward, the elastic telescopic rod 21 begins to be compressed, effectively preventing the sliding plate 11 from being stuck and unable to move further downward after the first slider 20 moves downward to a certain extent. In the above process, when the sliding plate 11 moves downward, the cleaning mud is driven to be squeezed out, and the connection between the cleaning mud and the power column 3 and the power connection plate 12 is effectively insulated, so as to effectively prevent leakage at the power connection, and the cleaning mud is connected to the power column 3 to clean the surrounding area, which effectively reduces the dust accumulation on the surface of the energy storage device 2 and reduces the influence of dust on the heat dissipation of the energy storage device 2.

In the above process, the connecting tube 6 and the power pole 3 at one end of the connecting plate 16 and the cross plate 24 are first fitted together. At this time, the first gear 29 can be driven to rotate by rotating the control lever 28. The rotation of the first gear 29 also drives the second gear 30 to rotate, thereby causing the reciprocating screw 31 to rotate, and the connecting plate 16 matched with the reciprocating screw 31 moves accordingly. Under the mutual cooperation of the second slide groove 26 and the second slider 27, the other connecting tube 6 is moved, so that the device can be suitable for energy storage devices 2 of different specifications and sizes, and can quickly detect power poles 3 with different spacings. While being convenient to carry, it ensures the safety of the detection process.
