[0002] During the routine maintenance of alkaline batteries used in subway vehicles, it is necessary to measure the battery electrolyte level and replenish distilled water, which takes a long time. If only the battery pack liquid level and distilled water are measured, the conventional method is to first measure the electrolyte liquid level with a transparent glass tube, and then use an ordinary large needle and hose. One person needs to draw barreled distilled water and stabilize the needle, and the other person holds the hose and adds distilled water. In this way, the dosage of distilled water is usually not easy to grasp. If too little is added, the liquid level may not meet the standard. A single battery may need to be added with distilled water more than 2 times, and the measurement is also more than 2 times. The working time generally takes about 3.5 hours, and it requires the cooperation of 2 people to complete.

The adjustment joint 203 is rotated to adjust the length of the electrode extending into the battery.

[0029] like Figure 2 and Figure 3As shown, the control box 4 is provided with a battery 18, a fuse 19, a first relay 20 and a second relay 21. The fuse 19, the first relay 20, the second relay 21 and the delivery pump 8 are connected in sequence.

[0030] The movable vehicle 1 includes a base frame 101 and a side panel 102 vertically fixed on the base frame 101, universal wheels 103 are arranged at the four bottom corners of the base frame 101, a handle 104 is arranged on the top of the side panel 102, the control box 4 is fixed on the side panel 102, and the water tank 3 is arranged on the base frame 101.

[0032] Before using the utility model, a water pipe is required to connect the first water pipe interface 5 with the water tank 3, and the liquid filling gun 2 is connected with the second water pipe interface 6 through the water pipe; a delivery pipe 9 is arranged on the gun body 201 and the gun head 202, one end of the delivery pipe 9 is connected with the water pipe coming out of the second water pipe interface 6, and the other end of the delivery pipe 9 is used to add liquid to the battery;

[0033] During the liquid adding process, first turn on the switch 22, and then put the gun head of the liquid adding gun 2 into the battery filling port. First observe whether the minimum liquid level indicator light 13 (yellow) or the high liquid level indicator light 16 (red) is on, and detect the liquid level status of the battery before adding liquid. If the red light is on, it means that the liquid level of the battery exceeds or reaches the standard height, then the main circuit of the circuit is disconnected and liquid cannot be added. If the red light is not on, liquid can be added normally. Press the self-reset button 17, and the normal liquid adding indicator light 14 (green light) is on, indicating that the device is adding liquid normally.

The flowmeter and flow display are placed in front of the water pump and connected by a soft water pipe. The volume of distilled water extracted by the water pump can be accurately read. The battery is a 12V, 8000mAH large-capacity lithium battery, which can be charged with a charger through the charging port to provide a safe and reliable power supply for delivery pumps, signal lights and other equipment. The relay controls the automatic stop of the delivery pump through circuit interlocking. The specific principle is as follows Figure 5 The flow rate of the delivery pump can be controlled by a flow adjustment potentiometer to achieve precise control of liquid addition.

[0035] The lower part of the adjusting joint is clamped on the filling port of the battery. When the liquid level height standards required for the battery are different, the relative height of the electrodes can be adjusted by lengthening or shortening the adjusting joint to adapt to the inspection and maintenance work of batteries of different models and meet diverse needs.

[0036] The portable shoulder strap inspection and maintenance device and the movable inspection and maintenance trolley of the utility model are independent of each other, and both can independently realize the battery inspection and maintenance functions, and have the same operation mode and the same internal circuit structure.
