Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery maintenance, and particularly relates to a water addition liquid level alarm device for a lead-acid battery. Background Technique

[0002] During the charge and discharge process of a common lead-acid battery, the evaporation of distilled water is caused by the increase in temperature, which changes the concentration of sulfuric acid in the battery, resulting in a decline in the charge and discharge capacity of the battery. Therefore, it is necessary to replenish distilled water to the battery in a timely manner.

[0003] Generally, when adding distilled water to the batteries of a lead-acid battery pack, only the naked eye or a measuring ruler can be used to control the liquid level height, resulting in a large error in the liquid level height of each battery, causing a deviation in the charge and discharge capacity of each battery, and having an adverse effect on the charge, discharge and use of the lead-acid battery.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 making creative efforts fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] As Figure 1 shown, a lead-acid battery water level alarm device includes: a fixing nut (1), a height adjusting slider (2), a liquid level sensor rod (3), a limiting device (4), a float (5), a base (6), a display and alarm device (7), a fixing pin (8), a cover (9), a height adjusting plate (10), and a wire (11).

[0021] The liquid level sensor rod (3) passes through the float (5) and the limiting device (4), and is connected to the height adjusting slider (2) through the fixing nut (1). The float (5) is arranged below the limiting device (4); the float (5) can slide freely on the liquid level sensor rod. Through the limiting action of the limiting device (4), the liquid level of each battery in the battery pack is made consistent.

[0022] A reed switch is provided inside the liquid level sensor rod (3) corresponding to the position of the limit device (4); a magnet is provided inside the float (5) and can float in the battery solution; the reed switch is connected to the display and alarm device (7) through a wire (11). When the magnet approaches the reed switch, the reed switch will be turned on, and then the internal circuit of the display and alarm device (7) will be turned on, causing the buzzer and indicator light in the display and alarm device (7) to emit sound and light signals.

[0023] The height adjustment plate (10) is provided with a moving adjustment groove for adjusting the height of the liquid level sensor rod (3). A bolt passes through the moving adjustment groove to fix the height adjustment slider (2) on the height adjustment plate (10); the function of this device is that the height of the liquid level sensor rod (3) can be finely adjusted, and then the alarm height of the float (5) can be adjusted, so as to realize the adjustable and controllable liquid level position after adding water to the lead-acid battery.

[0024] The display and alarm device (7) is arranged inside the base (6), and the height adjustment plate (10) is fixed on the side of the base (6); the cover (9) is connected to the base (6) through the fixing pin (8). Through this connection setting, the base (6) can be placed on the side of the battery water filling hole, and the liquid level sensor rod (3) is inserted into the battery water filling hole, so that water filling and display alarm can be carried out simultaneously. If the liquid level sensor rod (3) is arranged below the base (6), when the liquid level sensor rod (3) is inserted into the battery water filling hole, the base (6) will cover the battery water filling hole, and water filling operation cannot be carried out, affecting work efficiency.

[0025] As Figure 2 shown, the display and alarm device (7) includes a power supply, a buzzer and an indicator light. When the float (5) reaches the limit device (4), the display and alarm device (7) emits a sound and light alarm signal.

[0026] Furthermore, the cover (9) is made of a transparent material for observing the state of the indicator light.

[0027] During use, insert the liquid level sensor rod (3) into the battery water filling hole, place the base (6) on the side of the battery water filling hole, add distilled water to the battery. When the liquid level rises to the position of the limit device (4), the magnet inside the float turns on the reed switch, and then the circuit is turned on. The display and alarm device (7) emits a sound and light alarm to prompt the user to complete the water filling work.
