Abstract
The utility model discloses a waterproof device used for an energy storage battery. The waterproof device comprises a battery cover, a terminal hole arranged on the battery cover, a terminal of the battery cover, and a sealant between the terminal and the battery cover, wherein threads are formed in the terminal hole of the battery cover, the waterproof device is connected to the terminal hole through threads formed at the lower end of the waterproof device, the terminal is covered in the waterproof device, and a connecting wire perforation hole is formed at the top of the waterproof device. Since the connecting wire for the battery still adopts an external connection method, the problems of internal corrosion of the copper conductor, difficult casting of the pole and difficult assembly and charging are solved, not only the quality of the battery is guaranteed, but also convenience is brought for installation and maintenance for the customers; more importantly, the problem that the battery is soaked in water is fully solved, and the phenomenon of short circuit of positive and negative electrodes is avoided even if the battery is under water.
Description
Technical field
The utility model relates to solar energy photovoltaic system energy storage lead acid accumulator, is specifically related to storage battery water-tight device in use.
Background technology
Along with the growth that energy storage battery is used year number, market demand is increasing, and the client requires also more and more higher to the waterproof problem of energy-storage battery.At present; energy storage battery all needs to be embedded in underground in use, and its waterproof (battery short circuit) problem is difficult to solve, especially in southern rainy season; though battery has buried case as protection, because buried case all is to add a rubber blanket to form with screw is fastening in the middle of two plastic housings.According to Market Feedback since buried case plastic material time or because of its in two plastic housing connection procedures, use force unbalance when the contact area of two faces is tightened up a screw greatly, caused part water to enter in the buried case.For head it off, the producer that has casts in output lead in the end pole of battery, but do like this drawback is also arranged, if any 3.5 to 5 meters in customer requirement lead, in the middle of casting pole process, the copper wire in the lead must be divided into several bursts of plumbous the insides of removing to be cast to the end pole again like this, copper wire allows to expose anything but, and line is oversize must to be twined, freeze in the middle of the assembling process and during lid because of the lead inconvenient operation is arranged, can't detect every single battery in the battery charging process, and in use inside battery may climb to be damaged to and casts in the end pole because of the careless copper that exposes because of acid solution, make battery produce self discharge and pole internal corrosion, cause battery end of life, the client can't use when having contacted problem or long-term corrosion because of its inner lead with pole in use, can not place under repair.Other users directly coat fluid sealant on the copper end pole that battery is stretched, its gluing process must be to carry out after system construction is finished, and be inconvenient to behind the system construction carry out, the workman is reluctant to carry out this operation, and the specification requirement that is coated with fluid sealant is very high, being difficult to ensure the quality of products, is not very firm to the sealing of terminal, and the method does not obtain promoting yet.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy storage battery water-tight device, and good water-proof effect can overcome the defective that prior art exists.
The utility model is achieved through the following technical solutions:
A kind of energy storage battery water-tight device, comprise battery cover, terminal hole and terminal thereof on it are set, fluid sealant between terminal and the battery cover, the terminal aperture of described battery cover is provided with screw thread, described water-tight device covers in terminal in it by the terminal hole that is threadedly connected to of lower end setting, and the top is provided with connecting line and passes the hole.
The further improvement project of the utility model is, connecting line passes the hole edge portion and is connected with tubular part, described tubular part with pass hole concentric setting, and both diameters are identical, described diameter be slightly less than the connecting line diameter (with connecting line be tight fit).
The utility model further improvement project is, tubular part is to be made by soft rubber, and the top of tubular part is provided with rubber sleeve, connecting line can be tightened, and prevents into water.
The utility model further improvement project is, is provided with sealing ring between water-tight device lower end and fluid sealant, further prevents into water.
The utility model compared with prior art has following obvious advantage:
Because the connecting line of the utility model battery remains external, solved the copper conductor internal corrosion, casting pole and the difficult problem of assembling charging, both guaranteed the quality of battery, and made things convenient for client's installation and maintenance again, what is more important has solved the problem that battery is immersed in water fully, even can reach battery under water, do not have the both positive and negative polarity short circuit phenomenon yet and take place,, just more can play the effect of dual fail-safe if put it into again in the buried case.
