Description

Technical Field

[0001] The invention relates to the field of tubular batteries, and in particular to an acid water protective telescopic pipe for tubular batteries. Background Art

[0002] Tubular batteries are batteries with tubular plates. Because the active material is inside the tube and is not easy to fall off, it has a long life and is used in large quantities.

[0003] At present, during the acid cycle charging and discharging process of tubular single cells, when the acid cycle is completed, the acid tube needs to be pulled out. When pulling out the acid tube, there are the following problems:

[0004] 1) The acid remaining in the acid tube will inevitably be brought out and leak into the connecting strip and the pole hole of the battery. In the long run, it will corrode the connecting strip (copper) and the battery pole (copper), thereby damaging the battery pole and affecting the battery performance.

[0005] 2) Acid flows to the surface of the battery, which may cause acid corrosion and other safety hazards when it comes into contact with the human body;

[0006] 3) The acid flows to the surface of the battery and needs to be rinsed with clean water, wasting working time. Summary of the invention

[0007] According to the problems raised in the background technology, the present invention provides a tubular battery acid water protection telescopic pipe to solve the problems, and the present invention is further explained below.

[0008] A tubular battery acid water protective telescopic pipe comprises a "U"-shaped cover body, with protective fences for recovering acid connected to both sides of the bottom of the cover body, a sulfuric acid channel is hollowed out in the protective fence, and an acid leakage hole connected to the sulfuric acid channel is arranged on the protective fence; one end of the sulfuric acid channel is connected to a suction pump, and a groove is arranged on the cover body, extending along the cover body to the protective fence.

[0009] Preferably, the cover body is deformable and foldable, and can be stretched and contracted in a manner similar to a rubber telescopic hose, and the groove is also the site of tensile deformation.

[0010] Preferably, the groove is a V-shaped groove. Under the guidance of the large slope, the weight of the acid liquid is completely greater than the friction between the acid liquid and the groove, so the acid liquid flows smoothly to the guardrail, preventing the acid liquid from adhering to the groove.

[0011] Preferably, the V-shaped grooves are smoothed to reduce the adhesion of acid.

[0012] Preferably, the folded edge of the guardrail is inclined toward the groove side to form a return eaves to return the acid liquid to the groove, thereby preventing the acid liquid from rushing out of the guardrail.

[0013] Preferably, the height of the folded edge of the guardrail is such that the acid cannot rush out of the folded edge under the influence of gravity, friction and wind resistance, thereby preventing the backflow eaves from hindering the supplementary airflow.

[0014] Preferably, the acid leakage hole is arranged at the bend of the acid recovery guardrail, and one acid leakage hole is arranged on each side of the bend;

[0015] Preferably, when the cover is in a folded state, the deformation and extension at the bend cause the nearby acid leakage hole to be in a closed state, thereby maintaining the sulfuric acid channel in a closed and protected state when not in use.

[0016] Beneficial effects: Compared with the prior art, the present invention can prevent the acid remaining in the tube from leaking into the connecting strip and the pole hole of the battery when the tube is pulled out during acid circulation, corroding the connecting strip and the positive and negative poles of the battery, and avoiding affecting the battery performance; the sulfuric acid channel of the protective fence can reduce the acid flowing to the battery surface to cause acid corrosion when the human body contacts it, and other safety hazards; the sulfuric acid channel can also prevent the acid from flowing to the battery surface, omitting the process of water rinsing and saving working time.

[0021] Next, combine with Figure 1-3 A specific embodiment of the present invention is described in detail.

[0022] A tubular battery acid water protection telescopic pipe comprises a cover body 1 similar to a "U" shape, with protective fences 2 for recovering acid connected to both sides of the bottom of the cover body 1, a sulfuric acid channel 21 is hollowed out in the protective fence 2, and an acid leakage hole 22 connected to the sulfuric acid channel is arranged on the protective fence 2; one end of the sulfuric acid channel 21 is connected to a suction pump, and a groove 11 is arranged on the cover body 1. When the acid tube needs to be pulled out, the leaked acid flows along the groove 11 to the protective fence 2, and under the action of the suction pump, negative pressure is maintained in the sulfuric acid channel 21, and the acid retained in the protective fence 2 is sucked into the sulfuric acid channel 21 through the acid leakage hole 22 under the pressure difference and discharged to the outside.

[0023] The groove 11 can be formed on the non-deformable cover 1, or in this embodiment as a preferred embodiment, the cover 1 can be deformed and folded, and is made of corrosion-resistant rubber material, and can be stretched and contracted in a manner similar to a rubber telescopic hose, and the groove 11 is also the action site of the tensile deformation. The groove 11 is a V-shaped groove, and extends along the cover 1 to the guardrail 2. Under the guidance of the large slope, the weight of the acid is completely greater than the friction between it and the groove 11, and it flows smoothly to the guardrail 2, preventing the acid from adhering to the groove 11.

[0024] The U-shape of the cover 1 is adapted to the shape of the tubular battery to ensure that the tubular battery can be completely covered. After the acid falls on the top of the cover 1, it flows downward along the V-shaped groove. In order to reduce the adhesion of the acid, the V-shaped grooves are all smoothed.

[0025] During the downward flow of the acid liquid, the gravitational potential energy is gradually converted into the kinetic energy of the acid liquid. When the acid liquid enters the guardrail 2, its kinetic energy is the largest. Under inertia, the acid liquid will rush toward the folded edge of the guardrail 2, and under the action of the suction pump, the airflow also enters the acid leakage hole 22 along the groove 11, and the airflow has a boosting force on the acid liquid and accelerates the flow of the acid liquid. In order to prevent the acid liquid from rushing out of the guardrail 2, the folded edge of the guardrail 2 can be tilted toward the groove 11 to form a reflux eaves to return the acid liquid to the groove 11, or in the present embodiment, the folded edge of the guardrail 2 is set high enough to prevent the reflux eaves from hindering the supplementary airflow.

[0026] The acid leakage hole 22 is arranged at the bend of the acid recovery guardrail, and an acid leakage hole 22 is arranged on each side of the bend. After the acid flows into the negative pressure acid extraction pipeline from the hole, the acid is sucked away by the negative pressure. This design is different from the acid leakage hole 22 being arranged at the bend. When the cover body 1 is folded back and forth, the acid leakage hole 22 is reciprocatingly deformed to produce fatigue stress and be damaged. However, the symmetrical arrangement near the bend avoids the occurrence of large deformation, and the deformation extension of the bend during folding makes the nearby acid leakage hole 22 in a closed state, thereby maintaining the sulfuric acid channel 21 in a closed protective state when not in use.

[0027] The present invention has a simple structure and is easy to operate. Before a box-type tubular single battery is intubated during the acid circulation process, the present invention is laid on the battery connecting strip, and a corresponding tracheal needle is inserted into the sulfuric acid channel 21. When the acid tube is pulled out, the vacuum is turned on to form a negative pressure to collect the residual acid. It is also very convenient to clean, and flushing can be performed directly. In particular, when cleaning and drying the sulfuric acid channel 21, the sulfuric acid channel is in a closed state after the present invention is folded, and can be quickly cleaned and dried.

[0028] The present invention can prevent the acid liquid remaining in the tube from leaking into the connecting strip and the pole hole of the battery when the tube is pulled out during acid circulation, thereby corroding the connecting strip and the positive and negative poles of the battery and affecting the battery performance; the sulfuric acid channel of the protective fence can reduce the potential safety hazards such as acid corrosion caused by acid liquid flowing to the battery surface when the body contacts the battery; the sulfuric acid channel can also prevent the acid liquid from flowing to the battery surface, thereby omitting the process of water rinsing and saving working time.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
