[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Figure 1The structural schematic diagram of the discharge recovery device for retired batteries in the embodiment of the present utility model is shown. The discharge recovery device includes: a machine body 1, a plurality of discharge installation stations arranged on the machine body 1, and a discharge layer 11 located inside the machine body 1. A plurality of discharge resistors 12 are arranged in the discharge layer 11. The plurality of discharge installation stations are connected to the plurality of discharge resistors 12 in a one-to-one correspondence. Based on the discharge resistors 12, the power discharge operation of the retired batteries on the discharge installation stations is realized.

[0023] The discharge installation station includes an inclined plate 24, a fixed base 21 arranged at the bottom of the inclined plate 24, and a sliding locking block 22 arranged at the top of the inclined plate 24. An installation area for accommodating the retired battery is formed between the sliding locking block 22 and the fixed base 21. Based on the structure of the inclined plate 24, the positioning accuracy of the retired battery on the discharge installation station can be improved, and at the same time, the installation reliability of the retired battery at the discharge recovery station 2 can be improved.

[0024] Further, the sliding locking block 22 is slidably connected to the inclined plate 24, so that the sliding locking block 22 can slide along the inclined plate 24 to realize the pressing and fixing of the retired battery.

[0025] Specifically, a first electrode plate 212 is arranged on the fixed base 21, and a second electrode plate 222 is arranged on the sliding locking block 22. The first electrode plate 212 and the second electrode plate 222 are electrically connected to the discharge resistor 12 based on a connecting wire. One end of the retired battery is placed on the fixed base 21, so that one end of the retired battery is connected to the first electrode plate 212. Based on the sliding locking block 22 pressing the other end of the retired battery, the other end of the retired battery is connected to the second electrode plate 222 of the sliding locking block 22, thereby realizing the electrical connection between the retired battery and the first electrode plate 212 and the second electrode plate 222.

[0026] Further, the first electrode plate 212 and the second electrode plate 222 are connected to the discharge resistor 12 in the discharge layer 11 based on a connecting wire. By connecting the positive and negative electrodes of the retired battery to the first electrode plate 212 and the second electrode plate 222 respectively, the retired battery is connected to the discharge resistor 12, and a consumption circuit of the retired battery is constructed. The remaining electric energy of the retired battery is consumed by the heat generated by the discharge resistor 12.

[0027] Specifically, the sliding locking block 22 is further provided with a connecting frame 221, and the second electrode plate 222 is arranged on the connecting frame 221. A slide rail is arranged on the side wall of the inclined plate 24, and a slider 23 is arranged on the slide rail. The sliding locking block 22 is fixed on the slider 23. Based on the cooperation between the slider 23 and the slide rail, the sliding movement of the sliding locking block 22 on the inclined plate 24 is realized, so as to adjust the position of the sliding locking block 22 on the inclined plate 24.

[0028] Further, a bracket structure for an operator to hold is formed based on the connecting frame 221, so that the operator can hold the sliding locking block 22 and drive the sliding locking block 22 to slide on the inclined plate 24, thereby adjusting the position of the sliding locking block 22 to meet the locking and fixing requirements of the retired battery.

[0029] Further, a limiting rod 241 is arranged on the side wall of the inclined plate 24. The limiting rod 241 is arranged at the middle position of the slide rail. The limiting rod 241 is used to limit the moving position of the sliding locking block 22, so that the sliding locking block 22 can be kept at the middle position of the inclined plate 24. When the discharge and recovery station 2 is in a spatial state, a preset distance is maintained between the first electrode plate 212 and the second electrode plate 222, so as to facilitate the operator to perform the feeding and installation operation of the retired battery.

[0030] Specifically, the fixed base 21 is provided with a limiting coil 211. The limiting coil 211 is located above the first electrode plate 212. The size of the limiting coil 211 is adapted to the outer contour size of the retired battery. Based on the limiting coil 211, the retired battery can be limited, and the stability of the electrical connection between the retired battery and the fixed base 21 can be improved.

[0031] Further, the limiting coil 211 is an elastic telescopic coil, which is prepared by an elastic telescopic material, so that the limiting coil 211 has a certain expansion and contraction margin, so as to facilitate the operator to place the retired battery in the limiting coil 211.

[0032] Specifically, the discharge layer 11 is provided with an internal accommodation space, and the internal accommodation space is filled with a coolant. A plurality of discharge resistors 12 are located in the coolant. The coolant is used to realize heat exchange with the discharge resistors 12, so as to timely take away the heat generated by the discharge resistors 12, ensure the stable operation of the discharge recovery device, enable the discharge resistors 12 to meet the discharge operation of the remaining power of the retired battery, and realize the recovery of the retired battery.

[0033] Specifically, the capacity of the coolant is C1, and the volume of the discharge layer 11 is C2. The constraint relationship between C1 and C2 is: 60% ≤ C1 / C2 ≤ 85%, ensuring that the discharge resistor 12 in the discharge layer 11 can be completely accommodated in the coolant so that the coolant can perform sufficient heat exchange with the discharge resistor 12.

[0034] Further, a stirring mechanism may be provided in the discharge layer 11. Based on the stirring mechanism, the coolant in the discharge layer 11 can be driven to flow, so that the coolant in the discharge layer 11 can be uniformly heated, improving the heat dissipation reliability of the coolant to the discharge resistor 12.

[0035] Specifically, the discharge recovery device further includes a liquid storage tank 3. The liquid storage tank 3 is connected to the internal accommodation space of the discharge layer 11 based on a water pump 31. Spare coolant is placed in the liquid storage tank 3. After the discharge recovery device works for a long time, the liquid temperature of the coolant in the discharge layer 11 is detected by the temperature measuring component inside the machine body 1. When the liquid temperature is greater than the preset value, the spare coolant in the liquid storage tank 3 is pumped into the discharge layer 11 based on the water pump 31 for coolant replenishment, so that the temperature of the coolant in the discharge layer 11 drops to meet the heat exchange requirement of the coolant in the discharge layer 11 for the discharge resistor 12.

[0036] Further, the water pump 31 is used to realize the exchange of the coolant between the liquid storage tank 3 and the discharge layer 11. Based on the water pump 31, the coolant can be driven to flow from the liquid storage tank 3 to the discharge layer 11, or the coolant can be driven to flow from the discharge layer 11 to the liquid storage tank 3 to realize the dynamic balance of the coolant capacity in the discharge layer 11.

[0037] The embodiment of the present utility model provides a discharge recovery device for retired batteries. By setting a discharge installation station with an inclined plate 24, the battery is arranged obliquely, improving the positioning convenience during the discharge installation of retired batteries. The retired battery is fixed by a sliding locking method and electrically connected to the discharge resistor 12, improving the discharge recovery efficiency of retired batteries.
