Description

Technical Field

[0001] This invention belongs to the technical field of battery production tools, and particularly relates to an overflow container for batteries and its usage method. Background Technology

[0002] Valve-regulated lead-acid (VRLA) batteries are maintenance-free batteries that utilize a sealed structure and cathode absorption principle. Their core feature is that the electrolyte is adsorbed onto the AGM separator or solidified into a gel, achieving a fully sealed design. No water or acid replenishment is required during normal use. It utilizes an internal oxygen cycle mechanism, allowing oxygen generated at the positive electrode to diffuse to the negative electrode and be absorbed, thus significantly reducing water loss. Compared to traditional batteries, VRLA batteries offer advantages such as no acid mist leakage, installation in any orientation, low self-discharge rate, and good safety performance, making them widely used in UPS power supplies, communication base stations, and emergency lighting systems. However, it's important to note their sensitivity to charging voltage; overcharging or high temperatures can easily lead to thermal runaway and premature failure.

[0003] Valve-regulated lead-acid batteries are designed with a low electrolyte concentration. Depending on the plate area and number of plates, the assembly pressure of the electrode group is approximately 40–90 kPa. Because the AGM separator is compressed, a negative pressure of 0.08–0.09 MPa is required to evacuate the battery internally 5–8 times during electrolyte filling to ensure complete electrolyte filling. An overflow container (polypropylene) is then used to temporarily store the electrolyte that overflows during the formation process. Therefore, the overflow container is an indispensable tool in the battery formation process.

[0004] In existing technology, the overflow container is used by simply inserting it into the battery filling hole. However, overflow containers often tilt or tip over due to external forces, vibrations, or shaking, leading to leakage. Summary of the Invention

[0005] The purpose of this invention is to provide an overflow container for storage batteries and its usage method. The container body is stably supported by a stabilizing mechanism that contacts the battery cover, preventing the container body from tilting or tipping over due to external forces, vibrations, shaking, etc., thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An overflow container for storage batteries includes a single container or multiple containers arranged in parallel. The top of the container has a filling port, and the bottom of the container has a filling nozzle. The multiple containers are connected by rods. At least one set of stabilizing mechanisms is provided on both sides of the container. The stabilizing mechanism includes a lug plate connected to the outer wall of the container, and a stabilizing rod is rotatably connected to the lug plate. The outer wall of the container is connected to a buckle. When the stabilizing rod is flipped upward, it is engaged with the buckle. When it is flipped downward, it provides a stabilizing support.

[0007] A further embodiment of the present invention is that there are two ear plates arranged symmetrically, each ear plate has a through hole, and the tail end of the stabilizer rod has a pin hole. A pin passes through the first through hole, the pin hole and the second pin hole in sequence to connect the stabilizer rod to the ear plate. One end of the pin has a threaded hole, and a screw is threaded into the threaded hole.

[0008] A further aspect of the present invention is that the inner diameter of the through hole and the pin hole is D, and the outer diameter of the pin is D+0.15, so that the pin is interference-fitted with the through hole and the pin hole.

[0009] A further aspect of the present invention is that the back of the stabilizer bar is provided with a slot, and the stabilizer bar is engaged with the buckle through the slot.

[0010] A further aspect of the present invention is that the buckle is provided with a buffer groove, the minimum thickness dimension of the buckle is L, and the maximum thickness dimension is L+0.3.

[0011] A further aspect of the present invention is that the minimum width dimension of the card slot is L, and the maximum width dimension is L+0.3.

[0012] A further aspect of the present invention is that the front end of the stabilizer bar is provided with a sloping corrugated surface.

[0013] A further aspect of the present invention is that, when there is an odd number of pot bodies arranged side by side, the stabilizing mechanism is located on both sides of the central pot body and is distributed symmetrically along the axis.

[0014] A further aspect of the present invention is that, when there are an even number of pot bodies arranged side by side, the stabilizing mechanism is centrally symmetrically distributed on both sides of the two pot bodies in the very center.

[0015] A method for using an overflow container, employing the overflow container for storage batteries as described above, includes the following steps: During operation, first insert the electrolyte filling nozzle of the reservoir into the battery's filling hole, and add an appropriate amount of electrolyte into the reservoir through the filling port. After adding the electrolyte, the operator applies a pressure of 35N to 40N to the stabilizing rod and rotates it downwards, so that the inclined corrugated surface of the stabilizing rod contacts the battery cover surface, stabilizing and supporting the reservoir. Then, the battery is evacuated 5 to 8 times using a negative pressure of 0.08 to 0.09MPa to completely fill the battery with electrolyte from the reservoir.

[0016] After the work is completed, the operator applies a pulling force of 35N to 40N to the stabilizer bar to flip it upward. The buckle is squeezed into the slot through the buffer groove and then springs back to its original position, so that the stabilizer bar is locked in the buckle. Then the entire kettle body can be removed.

[0017] The beneficial effects of this invention are: The overflow container for storage batteries and its usage method of the present invention use a stabilizing mechanism to contact the battery cover surface to stably support the container body, so that the container body will not tilt or tip over due to external forces, vibrations, shaking, etc.

[0018] The overflow tank for storage batteries and its usage method of the present invention have a pin that is interference-fitted into the through hole and the pin hole, ensuring that after the pressure is applied and the battery is rotated into place, it will not retract or loosen due to vibration or reaction force, thereby maintaining a stable pressing state between the inclined corrugated surface and the battery cover for a long time.

[0019] The present invention relates to an overflow container for storage batteries and its method of use. The front end of the stabilizing rod is provided with a slanted corrugated surface, which increases friction and prevents the container from loosening or shifting during subsequent operations (such as vacuuming, filling, or waiting for absorption), thus ensuring the stability of the liquid filling process.

[0020] The present invention relates to an overflow container for storage batteries and its method of use. When the number of containers is an odd number arranged side by side, the stabilizing mechanism is located on both sides of the middle container in an axially symmetrical distribution. When the number of containers is an even number arranged side by side, the stabilizing mechanism is centrally symmetrically distributed on both sides of the two middle containers. This ensures that the stabilizing mechanism is symmetrically arranged on both sides of the container, making the container less prone to tilting or displacement. Attached Figure Description

[0038] The stabilizer bar 202 has a slot 209 on its back, and the stabilizer bar 202 is engaged with the buckle 203 through the slot 209.

[0039] The buckle 203 is provided with a buffer groove 210. The minimum thickness of the buckle 203 is L, and the maximum thickness is L+0.3.

[0040] The minimum width of the card slot 209 is L, and the maximum width is L+0.3.

[0041] The front end of the stabilizer bar 202 is provided with a sloping corrugated surface.

[0042] Example 2: As Figures 1-13 As shown, an overflow container for a storage battery 3 includes six containers 1 arranged side by side. Each container 1 has a filling port 101 at its top and a filling nozzle 102 at its bottom. The six containers 1 are connected by rods 103. At least one set of stabilizing mechanisms 2 is provided on both sides of each container 1. The stabilizing mechanism 2 includes a lug 201 connected to the outer wall of the container 1, and a stabilizing rod 202 is rotatably connected to the lug 201. A buckle 203 is connected to the outer wall of the container 1. When the stabilizing rod 202 is flipped upward, it is engaged with the buckle 203. When it is flipped downward, it provides stable support.

[0043] Two ear plates 201 are symmetrically arranged. Each ear plate 201 has a through hole 204. The tail end of the stabilizer rod 202 has a pin hole 205. The pin 206 passes through the first through hole 204, the pin hole 205 and the second pin hole 205 in sequence to connect the stabilizer rod 202 to the ear plate 201. One end of the pin 206 has a threaded hole 207, and the screw 208 is threaded into the threaded hole 207.

[0044] The inner diameter of the through hole 204 and the pin hole 205 is D, and the outer diameter of the pin 206 is D+0.15, so that the pin 206 is interference-fitted with the through hole 204 and the pin hole 205.

[0045] The stabilizer bar 202 has a slot 209 on its back, and the stabilizer bar 202 is engaged with the buckle 203 through the slot 209.

[0048] The front end of the stabilizer bar 202 is provided with a sloping corrugated surface.

[0049] The stabilizing mechanism 2 is centrally symmetrically distributed on both sides of the third and fourth pot bodies 1.

[0050] The specific working principle of this invention is as follows: like Figure 14 , 15As shown, during operation, firstly, the filling nozzle 102 of the pot body 1 is inserted into the filling hole of the battery 3, and an appropriate amount of electrolyte is added into the pot body 1 through the filling port 101. After the electrolyte is added, the operator applies a pressure of 35N to 40N to the stabilizing rod 202 and rotates it downwards, so that the inclined corrugated surface of the stabilizing rod 202 contacts the battery cover surface 301, thus stabilizing and supporting the pot body 1. Then, the battery is evacuated 5 to 8 times by applying a negative pressure of 0.08 to 0.09MPa to completely fill the battery 3 with electrolyte from the pot body 1.

[0051] After the work is completed, the operator applies a pulling force of 35N to 40N to the stabilizer bar 202 to flip the stabilizer bar 202 upward. The buckle 203 is squeezed into the buckle 209 through the buffer groove 210 and then springs back to its original position, so that the stabilizer bar 202 is locked in the buckle 203. Then the entire kettle body 1 can be removed.
