Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery maintenance equipment, in particular to a lead-acid battery maintenance device. Background Art

[0002] Lead-acid battery is a common electric vehicle battery. Its service life is related to factors such as charging and discharging technology, maintenance, and ambient temperature.

[0003] The application number 202222075161.X disclosed a lead-acid battery maintenance device, including a support tube, a slide rod is slidably installed inside the support tube; a float is provided at one end of the slide rod, and a scale value is provided on the outer circumference of the slide rod; the unit of the scale value is milliliter; a hole cover is also provided at the upper end of the support tube, and a connecting tube is provided on the hole cover. When the support rod is inserted into the liquid injection hole of the lead-acid battery, the float sinks into the interior of the battery, and the liquid level inside the battery is understood through the scale value on the slide rod. When the liquid level is low, distilled water is injected into the interior of the battery through the connecting tube, and then the numerical value of the scale value is read, which can ensure the accurate injection of distilled water.

[0004] In the above technical solution, when distilled water is introduced into the battery, it generates vibration when in contact with the liquid in the battery. As a result, the float is also in a vibrating state in the battery. The float is affected by the vibration of the liquid and drives the slide bar to slide up and down, making it difficult for people to read the value accurately.

[0005] Therefore, we propose a lead-acid battery maintenance device. Utility Model Content

[0006] The utility model mainly solves the above technical problems and provides a lead-acid battery maintenance device.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lead-acid battery maintenance device, comprising a liquid injection assembly, the liquid injection assembly comprising a plug connector, a connecting plate fixedly mounted on the plug connector, a limit ring fixedly sleeved on the connecting plate, a threaded sleeve threadedly mounted on the plug connector, the upper end of the threaded sleeve vertically extending upward through the connecting plate, a floating rod slidably mounted inside the threaded sleeve, and a scale line is arranged on the outer wall surface of the floating rod, a floating ball fixedly mounted on the lower end of the floating rod, and a pull ring fixedly mounted on the end of the floating rod away from the floating ball;

[0009] A liquid guide tube assembly is fixedly mounted on the bottom surface of the plug connector.

[0010] Preferably, the catheter assembly includes an inclined tube and a straight tube, which are fixedly connected and interconnected by an elastic connecting tube. The inclined tube is pulled downward so that the force on the inclined tube is distributed on the extension line of the straight tube. When the inclined tube is released, the inclined tube will be distributed in an inclined shape under the elastic force of the elastic connecting tube.

[0011] Preferably, a striking line is provided at the lower edge of the threaded sleeve.

[0012] Preferably, a vent is provided through the connecting plate, and a connecting hose is fixedly mounted on the connecting plate.

[0013] Preferably, the upper end of the straight pipe is fixedly connected to the connecting hose and communicates with each other.

[0014] Beneficial Effects

[0015] The utility model provides a lead-acid battery maintenance device, which has the following beneficial effects:

[0016] (1) When using the lead-acid battery maintenance device, the inclined tube is pulled to be distributed on the extension line of the straight tube, so that the plug connector drives the threaded sleeve and the liquid guide tube assembly to be inserted into the liquid filling port of the lead-acid battery body. After the inclined tube is distributed inside the lead-acid battery box, it rebounds and is distributed in an inclined shape. The plug connector is rotated to make the lower end of the inclined tube close to the inner wall surface of the lead-acid battery body. External distilled water is introduced into the lead-acid battery body through the connecting hose and the liquid guide tube assembly. By providing the liquid guide tube assembly, the distilled water flows downward along the inner wall surface of the lead-acid battery body, so that the introduced distilled water is slowly guided into the lead-acid battery body, which greatly reduces the shaking amplitude of the liquid in the lead-acid battery body, thereby reducing the fluctuation amplitude of the float, and achieving the effect of accurately controlling the injection amount.

[0017] (2) This lead-acid battery maintenance device, when it is necessary to directly add distilled water to the lead-acid battery body until the highest water level line, the liquid injection assembly is moved close to the lead-acid battery body so that the limit ring is aligned with the top surface of the lead-acid battery body, and the lower end distribution position of the threaded sleeve is adjusted by rotating the threaded sleeve back and forth until the eye-catching line is adjusted to align with the highest water level mark, and then the liquid injection assembly is inserted into the liquid injection port on the lead-acid battery body, and distilled water is introduced into the lead-acid battery body through the connecting hose and the liquid guide tube assembly. When the buoyancy of the float ball approaches the eye-catching line position upward, the lower end of the threaded sleeve limits the float ball, and the float rod will be relatively fixed at this time. When the float rod is relatively fixed, it means that the liquid in the lead-acid battery body has reached the highest water level line, achieving the effect of quickly injecting liquid to the highest water level.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] A lead-acid battery maintenance device, such as Figure 1-4As shown, it includes a liquid injection component 4, which includes a plug connector 401, a connecting plate 402 is fixedly installed on the plug connector 401, a limit ring 403 is fixedly sleeved on the connecting plate 402, a threaded sleeve 404 is threadedly installed on the plug connector 401, the upper end of the threaded sleeve 404 passes through the connecting plate 402 and is vertically distributed upward, a floating rod 405 is slidably installed inside the threaded sleeve 404, and a scale line is provided on the outer wall surface of the floating rod 405, a floating ball 406 is fixedly installed on the lower end of the floating rod 405, and a pull ring 407 is fixedly installed on the end of the floating rod 405 away from the floating ball 406;

[0028] The connecting plate 402 is provided with a vent 410, a connecting hose 409 is fixedly mounted on the connecting plate 402, and a liquid guide tube assembly 5 connected to the connecting hose 409 is fixedly mounted on the bottom surface of the plug connector 401;

[0029] The liquid guide tube assembly 5 includes an inclined tube 501 and a straight tube 502, which are fixedly connected and communicated with each other through an elastic connecting tube 503. The inclined tube 501 is pulled downward to distribute the force on the inclined tube 501 on the extension line of the straight tube 502. The inclined tube 501 is released and the inclined tube 501 is distributed in an inclined shape under the elastic force of the elastic connecting tube 503. When in use, the inclined tube 501 is pulled to distribute on the extension line of the straight tube 502, so that the plug connector 401 drives the threaded sleeve 404 and the liquid guide tube assembly 5 to be inserted into the liquid injection port of the lead-acid battery body. After the inclined tube 501 is distributed inside the lead-acid battery box, it rebounds and distributes in an inclined shape. The plug connector 401 is rotated to make the lower end port of the inclined tube 501 close to the inner wall surface of the lead-acid battery body, and external distilled water is passed through the connecting hose 40 9 and the liquid guide tube assembly 5 are introduced into the interior of the lead-acid battery body. The distilled water flows downward along the inner wall surface of the lead-acid battery body by providing the liquid guide tube assembly 5, so that the introduced distilled water is slowly guided into the lead-acid battery body, which greatly reduces the sloshing amplitude of the liquid in the lead-acid battery body, thereby reducing the fluctuation amplitude of the float 406. As the liquid in the lead-acid battery body increases, the buoyancy of the float 406 drives the float rod 405 to slide upward along the threaded sleeve 404. The scale lines provided on the outer wall surface of the float rod 405 facilitate people to accurately read the distribution position of the float 406. When the liquid injection assembly 4 is removed from the lead-acid battery body, the inclined tube 501 is squeezed by the inner wall surface of the liquid injection port during the outward movement and is vertically distributed at the lower end of the straight tube 502. At this time, it is convenient for the liquid injection assembly 4 to take the liquid guide tube assembly 5 away from the lead-acid battery body 1;

[0030] A striking line 408 is provided at the lower edge of the threaded sleeve 404. The liquid injection assembly 4 is moved close to the lead-acid battery body to align the limiting ring 403 with the top surface of the lead-acid battery body. The lower end distribution position of the threaded sleeve 404 is adjusted by rotating the threaded sleeve 404 back and forth until the striking line 408 is adjusted to align with the highest water level mark. Then the liquid injection assembly 4 is plugged into the liquid injection port on the lead-acid battery body, and distilled water is introduced into the lead-acid battery body through the connecting hose 409 and the liquid guide tube assembly 5. When the buoyancy of the float ball 406 approaches the position of the striking line 408 upward, the lower end of the threaded sleeve 404 limits the float ball 406. At this time, the float rod 405 will be relatively fixed. When the float rod 405 is relatively fixed, it means that the liquid in the lead-acid battery body has reached the highest water level, which is convenient for quickly filling the lead-acid battery body with distilled water.

[0031] The working principle of this utility model:

[0032] When in use, pull the inclined tube 501 to make it distributed on the extension line of the straight tube 502, so that the plug connector 401 drives the threaded sleeve 404 and the liquid guide tube assembly 5 to be inserted into the liquid filling port of the lead-acid battery body. After the inclined tube 501 is distributed inside the lead-acid battery box, it rebounds and is distributed in an inclined shape. The plug connector 401 is rotated to make the lower end port of the inclined tube 501 close to the inner wall surface of the lead-acid battery body, and the external distilled water is introduced into the lead-acid battery body through the connecting hose 409 and the liquid guide tube assembly 5. The distilled water flows downward along the inner wall surface of the lead-acid battery body by providing the liquid guide tube assembly 5, so that the introduced distilled water is slowly guided into the lead-acid battery body, which greatly reduces the shaking amplitude of the liquid in the lead-acid battery body, thereby reducing the fluctuation amplitude of the float 406.

[0033] When it is necessary to directly add distilled water to the lead-acid battery body until the highest water level line, the injection assembly 4 is moved close to the lead-acid battery body to align the limit ring 403 with the top surface of the lead-acid battery body, and the threaded sleeve 404 is rotated back and forth to adjust the distribution position of the lower end of the threaded sleeve 404 until the eye-catching line 408 is adjusted to align with the highest water level mark, and then the injection assembly 4 is plugged into the injection port on the lead-acid battery body, and distilled water is introduced into the lead-acid battery body through the connecting hose 409 and the liquid guide tube assembly 5. When the buoyancy of the float ball 406 approaches the position of the eye-catching line 408 upward, the lower end of the threaded sleeve 404 limits the float ball 406, and the float rod 405 will be relatively fixed at this time. When the float rod 405 is relatively fixed, it means that the liquid in the lead-acid battery body has reached the highest water level line, which is convenient for quickly filling the lead-acid battery body with distilled water.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
