Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and specifically relates to a battery discharge device. Background Technology

[0002] With the widespread use of batteries, a large number of used batteries are generated when they reach the end of their lifespan. These used batteries contain a significant amount of precious metals such as nickel, cobalt, manganese, and lithium, making them valuable for recycling. The primary issue to address in recycling used batteries is proper discharge. Although used batteries may not have a large internal charge, they still retain high voltage. Therefore, they must be fully discharged before recycling; otherwise, significant dangers will arise during dismantling. Currently, the main discharge methods are salt solution immersion and resistance discharge. Salt solution immersion is slow and requires a long discharge time; resistance discharge requires substantial manpower and resources, is costly, and requires manual connection. If the used battery is damaged, there is a risk of electric shock during discharge, and issues such as overheating also need to be addressed. Utility Model Content

Two power connectors are symmetrically arranged on the left and right sides inside the insulating discharge box, and the two power connectors are connected to form a circuit via a main wire. A battery capacity tester and a circuit switch are connected in series on the main wire, and a load group is connected in parallel within the circuit. The automatic connection assembly is located inside the insulating discharge box and is used to control the two power connectors on both sides to move synchronously towards the center and automatically connect with the positive and negative terminals of the used battery. Multiple heat dissipation windows are opened on the side wall of the insulating discharge box, and cooling fans are installed in the heat dissipation windows. The cooling fans are connected in series via shunt wires and in parallel to the main wire via shunt wires.

[0005] Furthermore, the automatic wiring assembly includes a dual-axis motor installed inside an insulating discharge box. The two output ends of the dual-axis motor are symmetrically fixed with screws of opposite thread directions.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a battery discharge device: Example

[0019] according to Figure 1 and Figure 2 As shown, a battery discharge device mainly includes an insulating discharge box 1. An insulating cover 13 is provided on the top of the insulating discharge box 1. An insulating battery holder 2 is located at the center of the box. Two legs at the bottom of the battery holder 2 are fixed to the bottom wall of the insulating discharge box 1. A clearance space is provided at the bottom for an automatic wiring assembly 6. A positioning assembly 4 for positioning used batteries 3 is provided inside the insulating discharge box 1. When discharging, the used batteries 3 are placed on the battery holder 2. When the used batteries 3 are placed in the insulating discharge box 1, the positioning assembly 4 can position the used batteries 3 at the center of the insulating discharge box 1, thereby achieving insulating discharge. The two positive and negative plugs 5 inside the box 1 can be aligned with the socket positions of the waste battery 3. The insulating discharge box 1 has two plugs 5 symmetrically arranged on the left and right, one is a positive plug and the other is a negative plug. The two plugs 5 are connected to form a circuit through the main wire 7. In the circuit, a load group 9 is also set in parallel through the main wire 7 and the shunt wire 11. When the two plugs are inserted into the positive and negative socket positions of the waste battery 3 respectively, the waste battery 3, the load group 9 and the main wire 7 form a complete circuit. The waste battery 3 provides power support in the circuit, and the load group 9 is used to consume the remaining power in the waste battery 3.

[0020] To replace manual plugging and unplugging, an automatic plugging assembly 6 is also installed inside the insulating discharge box 1. For example... Figure 3As shown, the automatic wiring assembly 6 includes a dual-axis motor 61 installed at the center of the inner bottom of the insulating discharge box 1. The dual-axis motor 61 is connected to mains power. Two screws 62 with opposite thread directions are symmetrically fixed to the two output ends of the dual-axis motor 61. The two screws 62 are horizontally arranged, and a screw sleeve 63 is threaded onto each of the two screws 62. The two screw sleeves 63 are symmetrically arranged left and right and can move relative to each other on the screws 62. A plug fixing sleeve 66 is fixed on the screw sleeve 63. Two power plugs 5 on the left and right sides are respectively fitted and fixed onto the same screw. The plug is fixed in the sleeve 66 on the side and corresponds to the positive and negative terminals of the waste battery 3. The main wire 7 extends into the insulating discharge box 1 and the part that connects to the power plug 5 is set as a spring wire. A sliding groove 64 is horizontally opened on the bottom wall of the insulating discharge box 1. A slider 65 that matches the sliding groove 64 is fixed on the screw sleeve 63. The screw sleeve 63 is oriented and slidably fitted in the sliding groove 64 by the slider 65. With the cooperation of the slider 65 and the sliding groove 64, the movement of the screw sleeve 63 can be guided, ensuring that the connection plug moves directionally and stably to connect with the waste battery 3.

[0021] When the power connector 5 is inserted into the positive and negative terminals of the used battery 3, the two screws 62 can be rotated by the dual-axis motor 61. With the cooperation of the screws 62 and the corresponding screw sleeves 63, the two plug fixing sleeves 66 can be controlled to move the corresponding power connector 5 to the middle until the two power connectors 5 are inserted into the positive and negative terminals of the used battery 3 respectively, so as to realize the automatic power connection of the battery and prevent the electric shock hazard that may occur when manually connecting the power.

[0022] like Figure 4 As shown, the positioning component 4 includes clamps 41 symmetrically arranged in the insulating discharge box 1. The clamps 41 are connected to the insulating discharge box 1 by top springs 42. The two ends of the top springs 42 are respectively connected to the corresponding surfaces of the clamps 41 and the insulating discharge box 1. In order to allow the waste battery 3 to be placed smoothly between the two clamps 41, the surface of the clamps 41 corresponding to the waste battery 3 is set as an arc surface structure. In this way, when the waste battery 3 is placed on the battery holder 2, the waste battery 3 can be smoothly inserted between the two clamps 41 through the arc surface clamps 41, and the elastic force of the top springs 42 on both sides will make the waste battery 3 be in the middle position of the battery holder 2, so as to determine the position of the positive and negative terminals of the waste battery 3.

[0023] A battery capacity tester 8 is connected in series with the main wire 7 in the circuit, which can monitor the remaining power in the used battery in real time. A circuit switch 10 is also connected in series with the main wire 7 to control the opening and closing of the circuit.

[0024] The load group 9 includes a load box 91 connected in parallel to the circuit of the main wire 7. The load box 91 has multiple slots, and each slot can be used to insert a load element 92. After the load element 92 is inserted into the load box 91, it means that it is connected in parallel to the circuit. The load element 92 consumes the power in the battery, and the number of load elements 92 can be adjusted according to the remaining power in the battery, thereby controlling the battery discharge rate.

[0025] In practical use, this battery discharge device first places the used battery 3 on the battery holder 2 of the insulating discharge box 1. The used battery 3 is clamped and limited by the cooperation between the clamp 41 and the top spring 42, so that the positive and negative terminals of the used battery 3 are on the axis of the insulating discharge box 1. Then the box cover 13 is closed, and the used battery 3 is sealed in the insulating discharge box 1. The insulating discharge box 1 provides protection for the battery during discharge. Next, the dual-axis motor 61 is started, driving the two screws 62 to rotate. With the cooperation of the screws 62 and the corresponding screw sleeves 63, the two plug fixing sleeves 66 are controlled to move the power connectors 5 to the center until the two power connectors 5 are respectively inserted into the positive and negative terminals of the used battery 3, completing the power connection of the used battery 3. Then the circuit switch 10 is closed, the circuit is energized, and the remaining power in the used battery 3 is consumed by the load to achieve rapid battery discharge. During the discharge process, the remaining power in the battery is observed by the battery capacity tester 8 until the power in the battery is completely consumed, completing the discharge of the remaining power of the battery. Example

[0026] Based on Example 1, this example addresses the problem of increased temperature that occurs during the rapid discharge of used batteries.

[0027] like Figure 2 and Figure 4 As shown, multiple heat dissipation windows are provided on the empty side wall of the insulating discharge box 1. Each heat dissipation window is equipped with a cooling fan 12. Adjacent cooling fans 12 are connected in series via shunt wires 11, and the entire fan assembly is connected in parallel to the main power line 7 via shunt wires 11. The purpose of this arrangement is to utilize the remaining power in the waste batteries to power the cooling fans 12, thus realizing the reuse of the remaining power in the waste batteries. After the cooling fans 12 are powered on and started, they can accelerate the airflow inside the insulating discharge box 1, achieving a heat dissipation effect, thereby providing cooling during the discharge of waste batteries and preventing the battery temperature from becoming too high during discharge.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
