Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid batteries, in particular to an exhaust and water removal device for lead-acid batteries. Background Art

[0002] Lead-acid battery is a battery that uses an acidic aqueous solution as an electrolyte. The working principle of lead-acid battery is that the positive and negative electrodes in the lead-acid battery are immersed in an electrolyte (dilute sulfuric acid), and 2V of power will be generated between the two electrodes. Since gas will be generated during the battery reaction, most of the lead-acid batteries on the market currently have exhaust channels.

[0003] Most of the lead-acid batteries on the market currently have exhaust channels, but the exhaust channels can usually only exhaust gas and cannot collect the dilute sulfuric acid discharged during the exhaust process. The discharged dilute sulfuric acid can easily corrode the lead-acid batteries, and the existing lead-acid batteries will contain water vapor in the exhausted gas. Lead-acid batteries are usually installed in confined spaces such as cabinets, and the water vapor they generate will affect the precision instruments in the cabinets, so it is necessary to improve the existing devices to meet actual needs. Utility Model Content

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lead-acid battery exhaust and water removal device, comprising a battery body, an exhaust pipe is installed through the top of the battery body, a motor is fixedly installed on the top of the exhaust pipe, a rotating shaft is fixedly installed on the motor output shaft, a retaining ring is fixedly installed on the bottom of the rotating shaft, a pressure detector is fixedly installed inside the exhaust pipe, a collecting box is fixedly installed on the outer wall of the exhaust pipe, a support plate is placed on the top of the battery body, an adjusting groove is opened through the side end of the support plate, a rotating rod is installed inside the adjusting groove, a gear is fixedly installed on the outer wall of the rotating rod, a rack is movably installed inside the adjusting groove, columns are symmetrically installed on the top of the support plate, fixing rings are fixedly installed on the side ends of the columns, and a U-shaped tube is installed on the inner wall of the fixing ring.

[0008] Preferably, exhaust holes are formed around the retaining ring and the exhaust pipe.

[0009] Through the above technical solution, when the exhaust pipe does not need to be exhausted, the exhaust holes of the baffle ring and the exhaust pipe are staggered, so that the exhaust pipe will not exhaust outwards. When exhaust is required, the exhaust holes of the baffle ring and the exhaust pipe correspond to each other, so that the gas is discharged from the exhaust pipe. In addition, the relative positions of the two groups of exhaust holes can be adjusted to adjust the exhaust gas rate.

[0010] Preferably, a drain pipe is installed through the bottom end of the collection box.

[0011] Through the above technical solution, when a certain amount of dilute sulfuric acid is collected in the collection box, it can be discharged through the drain pipe.

[0012] Preferably, the gear and rack are meshed.

[0013] Through the above technical solution, the gear and the rack are meshed, so that when the gear rotates, the rack can be driven to move. There are two groups of racks, which are arranged relatively around the gear.

[0014] Preferably, a fixing block is fixedly mounted on the side end of the rack.

[0015] Through the above technical solution, by providing a fixing block, it is convenient to use the fixing block to fix the support plate on the top of the battery body.

[0016] Preferably, a heating rod is installed inside the U-shaped tube, and the U-shaped tube and the collecting box are connected through a connecting tube.

[0017] Through the above technical solution, a mixture of powdered calcium oxide and spherical silica particles is placed inside the U-shaped tube, so that moisture in the gas can be absorbed, and the heating rod can dry the mixture of powdered calcium oxide and spherical silica particles.

[0018] Compared with the prior art, the utility model provides a lead-acid battery exhaust and water removal device, which has the following beneficial effects:

[0019] 1. The utility model places a support plate on the top of the battery body, and then twists the rotating rod, which drives the gear to rotate. The rotation of the gear drives the two sets of racks to move relative to each other. The movement of the rack drives the fixed block to move toward the outer wall of the battery body until the two sets of fixed blocks clamp the battery body, thereby fixing the support plate on the top of the battery body, and then clamping the U-shaped tube on the side end of the column, and connecting the connecting tube between the U-shaped tube and the collection box.

[0020] 2. The utility model is provided with a pressure detector. When the gas pressure inside the battery body is too high, the pressure detector sends out an alarm. At this time, the motor is started, and the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the baffle ring to rotate. The rotation of the baffle ring drives the exhaust holes on the outer wall of the baffle ring to rotate, so that the exhaust holes on the outer wall of the baffle ring and the exhaust holes on the outer wall of the exhaust pipe correspond to each other. At this time, the gas is discharged from the corresponding exhaust holes to the collection box and enters the U-shaped tube through the connecting tube. The U-shaped tube is provided with a mixture of powdered calcium oxide and spherical silicon dioxide particles, so that the moisture in the gas can be absorbed. When the gas pressure inside the battery body returns to normal, the motor is started again, and the motor rotates the exhaust holes on the outer wall of the baffle ring to be staggered with the exhaust holes on the outer wall of the exhaust pipe, thereby preventing the gas from being discharged.
