[0017] In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0018] The electrolyte tank 2 is used to store electrolyte, and then the stored electrolyte is pumped into the battery 1 through the water pump 3 to keep the electrolyte in the battery 1 in a rich liquid state.
[0019] The water pump 3 is used to extract the electrolyte in the electrolyte box 2 through the extraction pipe 4, and then add it to the battery 1 through the filling pipe 5, so as to ensure that the electrolyte in the battery 1 remains in a rich liquid state. Adding electrolyte to the battery 1 through the water pump 3 solves the problem of traditional manual addition that is time-consuming and labor-intensive, and causes electrolyte leakage.
[0020] The alarm mechanism is used to monitor the liquid level of the electrolyte in the electrolyte tank 2. When the liquid level drops to a certain height, a trigger signal is generated, and then the staff is provided with a sound and light alarm to replenish the electrolyte in time.
[0021] The limit rod 6 and the floating block 7 are welded or detachably fixed in the electrolyte tank 2 by bolts, so that the limit rod 6 is connected to the electrolyte tank 2. The floating block 7 is slidably connected to the limit rod 6, so that the floating block 7 can float on the upper surface of the electrolyte, and at the same time, the limit of the limit rod 6 is used to make the floating block 7 only move up and down along the limit rod 6. The limit rod 6 is non-circular, and the through hole on the floating block 7 that is close to the limit rod 6 is non-circular, so as to prevent the floating block 7 from rotating relative to the limit rod 6, thereby making the traction rope 8 connected to the floating block 7 wrapped around the limit rod 6.
[0022] A traction rope 8 has one end tied to the floating block 7 or detachably fixedly connected by bolts, and the other end tied to the traction block 11 or detachably fixedly connected by bolts, so that the floating block 7 and the traction block 11 are connected together by the traction rope 8, and then the traction block 11 is driven downward by the floating block 7 along the limit rod 6. A connecting hole 9 is opened on the electrolyte tank 2, and one end of the traction rope 8 passes through the connecting hole 9 and extends outside the electrolyte tank 2.
[0023] The protective shell 10 is detachably fixedly connected to the outside of the electrolyte box 2 by bolts, so as to protect the internal traction block 11 and traction spring 12 and limit the traction block 11 and traction spring 12 at the same time.
[0024] The traction block 11 and the traction spring 12 are arranged in the protective shell 10, and the traction spring 12 is located between the traction block 11 and the electrolyte tank 2, so that the traction spring 12 provides elastic force for the traction block 11, so that the traction rope 8 can push the traction block 11 away from the electrolyte tank 2 when it is relaxed.
[0025] The first trigger head 13, the second trigger head 14, the alarm light and the horn, the first trigger head 13 is detachably fixed on the traction block 11 by an adhesive or bolts, so that the first trigger head 13 and the traction block 11 are connected together to achieve simultaneous movement. The second trigger head 14 is detachably fixed in the electrolyte tank 2 in the protective shell 10 by an adhesive or bolts, and the first trigger head 13 and the second trigger head 14 are on the same vertical line, so that when the traction block 11 moves to a certain distance in the direction close to the electrolyte tank 2, the first trigger head 13 and the second trigger head 14 collide with each other, thereby generating a trigger signal. The first trigger head 13, the second trigger head 14, the alarm light and the horn are electrically connected to the control module assembly, forming a trigger signal when the first trigger head 13 and the second trigger head 14 contact, and the signal is transmitted to the control module assembly, and the control module assembly controls the alarm light and the horn to emit an audible and visual alarm structure, thereby reminding the staff to replenish the electrolyte in the electrolyte tank 2 in time.
[0026] The overflow prevention mechanism prevents excessive electrolyte from being pumped into the battery 1 by the pump 3, causing the electrolyte to overflow and corrode external objects. The overflow prevention mechanism is located above the battery 1, so that the electrolyte overflowing from the battery 1 can be collected by the anti-electrolysis mechanism, and the collected electrolyte is replenished after the electrolyte in the battery 1 is consumed, thereby avoiding electrolyte waste.
[0027] The anti-overflow tube 17 and the anti-overflow cylinder 18 are used to connect the exhaust hole of the battery 1 and the anti-overflow cylinder 18, so that when too much electrolyte is pumped into the battery 1, it is discharged from the exhaust hole and transported along the anti-overflow tube 17 to the anti-overflow cylinder 18 for storage.
[0028] The vertical cross-section of the space inside the overflow prevention head 20, the overflow prevention seat 19, and the overflow prevention tube 18 is an inverted T-shaped. The overflow prevention seat 19 and the overflow prevention head 20 are fixed and detachably connected by bolts or adhesives in the cavity with a larger diameter inside the overflow prevention tube 18, and the overflow prevention head 20 is close to the cavity with a smaller diameter inside the overflow prevention tube 18, so that when the electrolyte enters the overflow prevention tube 18, the overflow prevention head 20 and the overflow prevention seat 19 will float until the overflow prevention head 20 blocks the entrance of the cavity with a smaller diameter inside the overflow prevention tube 18, and a trigger signal is generated at the same time. An exhaust groove 21 is provided at one end of the overflow prevention seat 19 near the connection between the overflow prevention tube 17 and the overflow prevention tube 18, so that when the electrolyte does not enter the overflow prevention tube 18, the gas generated in the battery 1 is discharged through the exhaust groove 21.
[0029] The third trigger head 23 and the fourth trigger head 25 are connected to the end of the overflow prevention head 20 away from the overflow prevention seat 19 through the overflow prevention spring 22, so that the third trigger head 23 is connected to the overflow prevention head 20 through the overflow prevention spring 22, so that they can move at the same time, and the overflow prevention spring 22 is used to provide the third trigger head 23 with a relative movement ability to the overflow prevention head 20, so that the third trigger head 23 and the fourth trigger head 25 can better conflict. The fourth trigger head 25 is connected to the end with a smaller diameter of the overflow prevention tube 18 through the fixing rod 24, so that the fourth trigger head 25 is connected to the inner wall of the end with a smaller diameter of the overflow prevention tube 18 through the fixing rod 24. The third trigger head 23 and the fourth trigger head 25 are electrically connected to the control module assembly, so that when the third trigger head 23 and the fourth trigger head 25 conflict, a trigger signal is generated and the signal is transmitted to the control module assembly, and the control module assembly controls the water pump 3 to stop working.
[0030] The control module assembly is a common single-chip microcomputer control circuit board assembly on the market, and is used to receive and process the trigger signals of the first trigger head 13 and the second trigger head 14 , the third trigger head 23 and the fourth trigger head 25 .
[0031] The waterproof breathable membrane 26 is a common waterproof breathable material on the market and is disposed at the end of the anti-overflow tube 18 with a smaller diameter to prevent external moisture or dust and other debris from entering the battery 1 through the anti-overflow tube 18 .
[0032] A liquid level monitoring sensor commonly used on the market for detecting the liquid level height inside the container is provided in the filling port of the battery 1. The liquid level monitoring sensor is electrically connected to the control module assembly, so that the liquid level height of the electrolyte inside the battery 1 is monitored by the liquid level monitoring sensor. When the liquid level of the electrolyte is lower than a certain height, the control module assembly controls the water pump 3 to pump the electrolyte into the battery 1, thereby realizing automatic electrolyte replenishment of the battery 1, so that the battery 1 always remains in a liquid-rich state.
[0033] Unless otherwise specified, the device elements involved in the above embodiments are all conventional device elements, and the structural settings, working modes or control modes involved are all conventional settings, working modes or control modes in the art unless otherwise specified.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
