Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery leakage detection, in particular to a multi-point battery leakage detection system. Background Art
[0002] The basic characteristic of lead-acid batteries is that they do not require acid or water maintenance during use. The battery is a sealed structure, and a one-way exhaust valve (also called a safety valve) is provided on the battery cover. The function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed as an air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens to discharge the gas, and then automatically closes the valve to prevent air from entering the battery.
[0003] The utility model patent with publication number CN217132504U discloses a lead-acid battery leakage detection device. In this scheme, a battery body and a detection tray are set up, a liquid receiving groove is opened on the top of the detection tray and at a position corresponding to the battery body, and multiple groups of first contact copper sheets and second contact copper sheets with the same interval and cross-arranged are arranged inside the liquid receiving groove. A wire harness protection base is set at the bottom of the detection tray, and an insulated wire is set on the front of the wire harness protection base. The two ends of the insulated wire pass through the left and right sides of the wire harness protection base respectively, and the middle section of the insulated wire is connected to a power supply group and an alarm. The bottoms of the first contact copper sheet and the second contact copper sheet are both connected to the detection wire. Whether there is a leakage problem in the lead-acid battery can be quickly detected, and the overall structural design is compact, and the detection efficiency is efficient and accurate.
[0004] However, there are still some shortcomings in the above scheme. The above scheme collects the electrolyte and detects the leakage by receiving the leaked electrolyte. When the amount of electrolyte leakage is small, the electrolyte cannot gather in the collection structure and contact the detection structure, so it is impossible to detect a small amount of leakage. At the same time, the above scheme can only detect the state of leakage, but cannot detect the location of leakage. When inspecting, the staff still need to find the leakage location on the outer wall of the battery, which reduces the maintenance efficiency of leakage. In view of this, we propose a multi-point battery leakage detection system. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example 1
[0027] A multi-point battery leakage detection system, such as Figure 1-Figure 5As shown in the figure, it includes a battery 1; a detection mechanism 2 is provided at the bottom end of the battery 1. The detection mechanism 2 includes a bracket 201, and the bracket 201 is movably connected to the four corners at the bottom end of the battery 1. The top end of the bracket 201 is movably connected with an adjusting frame 202. The adjusting frame 202 is sleeved outside the battery 1. Conductive rods 203 are fixedly connected to the inner side of the adjusting frame 202 and the inner side of the bracket 201. A wire winding ring 204 is sleeved on the conductive rod 203, and a conductive wire 205 is wound around the wire winding ring 204. The detection mechanism 2 can monitor the liquid leakage of the battery 1 in real time and give a warning in time when the battery 1 leaks liquid. The adjusting frame 202 and the bracket 201 are respectively sleeved outside and at the bottom end of the battery 1. The adjusting frame 202 can adjust the detection height or according to the height of the battery 1. The wire winding ring 204 is made of insulating material, and the end of the conductive wire 205 wound around the wire winding ring 204 is fixedly connected to the conductive rod 203, so that one end of the conductive wire 205 is in a connected state with the conductive rod 203, and the other end is in a disconnected state from the other conductive rod 203 through the insulating wire winding ring 204. Therefore, the conductive rod 203 inside the adjusting frame 202 and the conductive rod 203 inside the bracket 201 are in a disconnected state, and the conductive wires 205 are adjacent and do not touch. When the battery 1 leaks liquid, the leaked conductive liquid will contact the conductive wire 205 when flowing along the side wall of the battery 1 and make two adjacent conductive wires 205 connected. The conductive rod 203 inside the adjusting frame 202 and the conductive rod 203 inside the bracket 201, that is, the detected circuit is随之 in a connected state, and the liquid leakage can be detected. The end of the conductive wire 205 is slidably connected to the conductive rod 203, and the conductive wire 205 and the wire winding ring 204 are arranged in a staggered manner on the conductive rod 203. Connecting rods 206 are fixedly connected to the inside of the bracket 201 and the inside of the adjusting frame 202. The conductive rod 203 and the end of the connecting rod 206 are arranged in contact with each other. The staggered conductive wires 205 can facilitate the detection of liquid leakage, and the connecting rod 206 can keep the circuit inside the conductive rod 203 in a connected state by abutting against the conductive rod 203. A collecting plate 207 is rotatably connected to the inner sides of the adjusting frame 202 and the bracket 201. A support ring 208 is fixedly connected to the side of the collecting plate 207, and the support ring 208 is rotatably connected to the conductive rod 203. Fixing grooves 209 corresponding to the conductive wires 205 are formed on the collecting plate 207. The structure of the collecting plate 207 can rotate towards the battery 1 and guide the liquid leakage through the inclined plane formed after contacting the battery 1, improving the detection effect of the liquid leakage of the battery 1. The conductive rod 203 has a "U" - shaped structure, and the two ends of the conductive rod 203 are respectively rotatably connected to the inner sides of the adjusting frame 202 and the bracket 201. Coil springs are fixedly connected to the inner side of the wire winding ring 204 and both ends of the conductive rod 203. The "U" - shaped conductive rod 203 can fix the conductive wire 205 and can rotate towards the battery 1 at the same time, making the conductive wire 205 closely adhere to the side wall of the battery 1, so that the battery 1 can also detect the liquid leakage when a small amount of liquid leaks out. The coil spring structure can drive the conductive rod 203.The conductive rod 203 keeps the tendency to rotate inward, and the coil spring can drive the winding ring 204 to keep the winding ring 204 storing the conductive wire 205, and tighten the conductive wire 205 after the adjustment frame 202 moves, so as to avoid false alarm caused by the conductive wire 205 contacting each other due to relaxation.
[0028] Example 2
[0029] like Figure 1 , Figure 5 As shown, a power supply device 3 and a buzzer 4 are fixedly connected to the outer side of the bracket 201, and a buffer pad 5 is fixedly connected to the inner side of the bracket 201. The power supply device 3 can provide power to the detection mechanism 2, so as to detect the leakage of the battery 1, and alarm through the buzzer 4 after the leakage is detected. A clamping mechanism 6 is provided on the detection mechanism 2, and the clamping mechanism 6 includes a screw 601, which is meshed and connected to the adjustment frame 202. A buffer block 602 is fixedly connected to one end of the screw 601. The clamping mechanism 6 can clamp the detection mechanism 2, and the buffer block 602 structure can buffer the screw 601 during the clamping process to reduce the damage to the battery 1 shell. The other end of the screw 601 is fixedly connected to a driving handle 603, and a handle is fixedly connected to the driving handle 603.
[0030] When the multi-point battery leakage detection system of the utility model is used, the bracket 201 and the adjustment bracket 202 are slid from the top of the battery 1 to the bottom of the battery 1. During the sliding process, the adjustment bracket 202 is fixed at a set position. At the same time, the screw 601 is rotated by the driving handle 603 to fix the adjustment bracket 202 on the battery 1. At the same time, the bracket 201 continues to slide downward until it moves to the bottom of the battery 1. When the bracket 201 and the adjustment bracket 202 move away from each other, the conductive wire 205 is pulled out from the winding ring 204 and kept taut under the action of the coil spring. state, and the conductive rod 203 rotates toward the battery 1 under the action of the coil spring, and drives the conductive wire 205 to be close to the side wall of the battery 1. When the battery 1 leaks, the leaked liquid flows downward along the side wall of the battery 1. When the liquid flows to the collecting plate 207, the liquid flows along the collecting plate 207 to the conductive rod 203 and connects the adjacent conductive wires 205. The detection circuit is then connected and an alarm is sounded for leakage. When the side wall of the battery 1 leaks, the leaked electrolyte contacts the conductive wire 205 and connects the two adjacent conductive wires 205.
