[0002] The battery cover of the valve-regulated lead-acid battery is equipped with a one-way exhaust valve (also called a safety valve). The function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed as an air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens to exhaust the gas, and then automatically closes the valve to prevent air from entering the battery. However, when an internal fault occurs in the valve-regulated lead-acid battery, the electrolyte will spray out from the safety valve. At the same time, when the safety valve is vented or in other scenarios, the electrolyte will also flow out. The electrolyte of the valve-regulated lead-acid battery contains a large amount of harmful substances such as sulfuric acid and lead. If it comes into contact with the skin, eyes or is accidentally ingested, it may cause chemical burns, poisoning and other hazards; the harmful substances in the electrolyte will pollute the soil, water sources, vegetation, etc., and affect the ecological environment; at the same time, it will corrode the metal parts of the equipment and cause equipment damage.

[0044] The electrolyte leakage prevention device of the first embodiment of the utility model includes a shell 100 and a leakage detection component 200. The shell 100 is provided with an opening 120. The shell 100 is covered to the outside of the safety valve 600 of the valve-regulated lead-acid battery through the opening 120; the leakage detection component 200 is arranged on the inside of the shell 100.
[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electrolyte leakage prevention device of the embodiment of the utility model provides an electrolyte leakage detection and leakage prevention device of a safety valve 600 of a valve-regulated lead-acid battery for a data center, wherein the shell 100 is arranged on the upper cover 420 of the lead-acid battery, and the opening 120 is arranged around the safety valve 600 to ensure that the shell 100 can completely cover the safety valve 600, and a leakage-proof space is constructed outside the safety valve 600, thereby, the gas discharged from the safety valve 600 and the leaked electrolyte both enter the leakage-proof space, which can effectively prevent the leakage of the electrolyte, and can control the splashing or leakage range of the electrolyte within a certain range, thereby preventing the electrolyte from causing harm to personal safety, the environment and equipment, and can minimize the adverse effects caused by the leakage of the electrolyte from the valve-regulated lead-acid battery safety valve 600 without affecting the normal operation of the safety valve 600.
[0046] A liquid leakage detection assembly 200 is disposed inside the housing 100. The liquid leakage detection assembly 200 can detect the electrolyte in the anti-leakage space, that is, the electrolyte carried in the gas discharged by the safety valve 600 or the electrolyte leaked from the safety valve 600. After contacting the liquid leakage detection assembly 200, it can be detected. When electrolyte leakage is detected, the operation and maintenance personnel are notified in time to handle it. In addition, the structure of the housing 100 and the liquid leakage detection assembly 200 has the characteristics of small size, low cost, and easy implementation.
[0047] In this embodiment, the material of the shell 100 can be ABS material, which has the advantages of high flame retardancy, good heat resistance, good dimensional stability, good impact resistance, no cracking when impacted in a low temperature environment, good heat sealing and glue sealing effects, and the material does not contain harmful and toxic heavy metals such as cadmium and chromium.
[0048] According to an embodiment of the utility model, the liquid leakage detection assembly 200 includes a first liquid leakage sensor 210, which is arranged on the top wall of the housing 100, and the top wall is opposite to the opening 120. In this embodiment, the first liquid leakage sensor 210 is arranged on the inner wall of the housing 100, which is used to detect liquid leakage when electrolyte splashes in the anti-leakage space. Since the electrolyte safety valve 600 will be discharged in the form of a jet during the exhaust process, the electrolyte will splash to a certain height in the anti-leakage space. The first liquid leakage sensor 210 is arranged on the top wall of the housing 100, so that the leakage can be detected at the highest position.
[0049] In other embodiments, the first liquid leakage sensor 210 may also be disposed on other side walls of the inner side of the housing 100 except the top wall, and can also detect the electrolyte sprayed when the safety valve 600 is exhausted.
[0050] According to an embodiment of the utility model, the leakage detection component 200 also includes a second leakage sensor 220, and the second leakage sensor 220 is arranged at the inner edge of the opening 120. In this embodiment, the inner wall of the shell 100 is also provided with a second leakage sensor 220, which is used to detect leakage when there is electrolyte leakage in the anti-leakage space. Since when the electrolyte safety valve 600 leaks in a non-splashing form, the electrolyte will flow on the surface of the lead-acid battery, that is, it will spread to the inner edge of the opening 120 in the anti-leakage space, so the second leakage sensor 220 is arranged at the inner edge of the opening 120, and the leakage can be detected at the edge position of the opening 120, that is, the second leakage sensor 220 is arranged around the edges of the opening 120, which is used to detect leakage of the safety valve 600 in a non-splashing scenario.
[0051] In this embodiment, the first liquid leakage sensor 210 and the second liquid leakage sensor 220 are both disposed on the inner side of the housing 100 . In other embodiments, at least one of the first liquid leakage sensor 210 and the second liquid leakage sensor 220 may be disposed.
[0052] According to an embodiment of the utility model, the second liquid leakage sensor 220 is annularly arranged at the opening 120. In this embodiment, the second liquid leakage sensor 220 is linear and can be arranged around the inner edge of the opening 120, that is, the detection range of the second liquid leakage sensor 220 covers the entire range of the opening 120, and can detect non-splashing leakage of the electrolyte in a more comprehensive manner.
[0053] In other embodiments, the second liquid leakage sensor 220 may also adopt a local point measurement structure, and a plurality of second liquid leakage sensors 220 are evenly distributed on the inner edge of the opening 120 of the housing 100 .
[0054] According to an embodiment of the utility model, a first adsorption member is further provided on the inner side of the housing 100, and the first adsorption member is suitable for adsorbing the electrolyte sprayed from the safety valve 600. The first adsorption member is arranged at a position on the inner side of the housing 100 except for the leakage detection assembly 200. In this embodiment, in addition to the leakage detection assembly 200, the inner wall of the housing 100 is also provided with a first adsorption member to adsorb the electrolyte splashed onto the inner wall of the housing 100, to prevent the electrolyte from accumulating and remaining on the inner wall of the housing 100, and corroding and damaging the housing 100 due to direct contact with the housing 100. In addition, the first adsorption member can also have a certain adsorption and limiting effect on the electrolyte. After being adsorbed by the first adsorption member, the electrolyte will no longer gather and flow along the inner wall of the housing 100 to leak out.
[0055] In one embodiment, the first adsorbent may be an absorption net, and the lower end of the absorption net may be fixedly connected to a guide rod, through which the absorption net is drained into an electrolyte recovery component such as a storage box to prevent the electrolyte from flowing irregularly and uncontrolled. Alternatively, the lower end of the absorption net is directly connected to a storage box, and excessive electrolyte flows downward under the influence of gravity and directly enters the storage box from the absorption net.
[0056] According to an embodiment of the utility model, the housing 100 is provided with a vent hole 110, and the vent hole 110 connects the interior of the housing 100 with the outside world. A second adsorbent is provided on the inner side of the vent hole 110, and the second adsorbent is suitable for adsorbing the electrolyte in the gas discharged from the vent hole 110. In this embodiment, the side wall of the housing 100 has a vent hole 110, which can keep the anti-leakage space in normal communication with the outside world, ensuring that the safety valve 600 can work normally to exhaust. The second adsorbent covers the vent hole 110, that is, in the anti-leakage space, when the gas discharged by the safety valve 600 is discharged through the vent hole 110, it will first pass through or simultaneously pass through the second adsorbent for adsorption, and then be discharged to the external environment. The second adsorbent can adsorb the electrolyte carried in the gas, and can also prevent the electrolyte from being discharged with the gas. The gas is discharged after being filtered by the second adsorbent. After filtering, the electrolyte leakage can be effectively prevented, which increases the safety of the lead-acid battery. In this embodiment, the second adsorbent can be an adsorbent cotton.
[0057] According to an embodiment of the utility model, the housing 100 is provided with a communication interface 130, and the communication interface 130 is connected to the leakage detection component 200. In this embodiment, the communication interface 130 is used to connect the first leakage sensor 210 and the second leakage sensor 220 to the data center monitoring system. When any one of the first leakage sensor 210 and the second leakage sensor 220 detects electrolyte, the data center monitoring system can issue a warning in time to remind the data center operation and maintenance personnel to go to the site for inspection and processing in time. In other embodiments, the communication interface 130 can also be provided with a corresponding control panel or alarm, etc. When any one of the first leakage sensor 210 and the second leakage sensor 220 detects electrolyte, the alarm can directly issue an alarm, or the control panel can directly give an operation and processing prompt, so that the operation and maintenance personnel can be informed of the situation and handle it as soon as possible.
[0058] According to an embodiment of the utility model, the opening 120 is provided with a sealing ring 140, and the sealing ring 140 is used to seal the housing 100 and the valve-regulated lead-acid battery. In this embodiment, the sealing ring 140 is provided on the end surface of the opening 120, that is, the sealing ring 140 is provided at the position where the opening 120 contacts the lead-acid battery, so that the leaked electrolyte can be limited within the range enclosed by the opening 120, that is, within the range of the anti-leakage space, to prevent it from flowing around and overflowing.
[0059] According to an embodiment of the utility model, the electrolyte leakage prevention device further includes a fixing member 300, which is disposed on the housing 100 and is suitable for being detachably connected to the valve-regulated lead-acid battery. In this embodiment, the fixing member 300 is disposed on the housing 100, and the housing 100 can be connected to the lead-acid battery through the fixing member 300, and the housing 100 can also be removed from the lead-acid battery through the fixing member 300.
[0060] In this embodiment, the fixing member 300 may be a fixing belt, and the electrolyte leakage prevention device may be fixed to the upper cover 420 of the valve-regulated lead-acid battery using a nano double-sided adhesive. In other embodiments, the fixing member 300 may be a card slot and a buckle arrangement, one of the card slot and the buckle is arranged on the housing 100, and the other of the card slot and the buckle is arranged on the upper cover 420 of the valve-regulated lead-acid battery to cooperate.
[0061] According to the valve-regulated lead-acid battery of the second embodiment of the utility model, it includes a shell 400, a battery body, a safety valve 600 and the electrolyte leakage prevention device as described above, the shell 400 includes a shell portion 410 and an upper cover 420, and the upper cover 420 and the shell portion 410 enclose a containing space; the battery body is arranged in the containing space; the safety valve 600 is arranged outside the containing space and fixedly arranged on the upper cover 420, and the safety valve 600 is connected to the containing space; the opening 120 is connected to the upper cover 420.
[0062] The valve-regulated lead-acid battery adopts a sealed structure, so the internal electrolyte will not leak out, thus ensuring the safety and reliability of the battery; the special design and materials can make the battery life up to 5-10 years, and under normal use, the battery maintenance is very low; it does not need to be frequently watered or deeply discharged, so the maintenance cost is very low; the charging efficiency is very high, which can reach more than 90%, and it can also output a stable current during discharge; multiple protection measures are adopted, such as overcharge protection, over-discharge protection, short-circuit protection, etc., to ensure the safety and reliability of the battery, and it is widely used in data centers. In the electrolyte leakage detection and anti-leakage device of the valve-regulated lead-acid battery safety valve 600 in the data center, the shell 100 can prevent the electrolyte from splashing to other areas when the valve-regulated lead-acid battery safety valve 600 splashes electrolyte.
[0063] As an important part of the UPS (uninterruptible power supply) system, the battery provides a stable power supply for the data center server and other key equipment to protect them from power fluctuations and sudden power outages, protect the data and equipment in the data center, and ensure the high availability and stability of the data center. Due to different battery specifications and models, the number and position of the safety valve 600 may be different, and the position of the pole 500 may be different.
[0064] In the valve-regulated lead-acid battery of the embodiment of the utility model, the electrolyte leakage prevention device is slightly larger than the safety valve 600 of the battery body. When in use, an electrolyte leakage device can be mounted on all the safety valves 600 on the outer shell 400 of each battery body and fixed on the upper cover 420 of the valve-regulated lead-acid battery, thereby preventing damage to personal safety, environmental safety and equipment safety caused by leakage or splashing of the valve-regulated lead-acid battery safety valve 600 without affecting the normal operation of the valve-regulated lead-acid battery safety valve 600.
