Abstract

This invention relates to the field of battery protection technology, and more particularly to a UPS-compatible battery leakage protection device. The device includes a battery casing, with mounting bases movably connected to the positive and negative terminals of the battery casing. A terminal leakage sealing mechanism is fixedly mounted on the top of the mounting base. An inflation frame for automatically inflating the terminal leakage sealing mechanism is slidably fitted onto the inner wall of the mounting base. A transmission mechanism is fixedly connected to the inner wall of the mounting base. An automatic terminal separation mechanism is located above the mounting base. A push plate is located on the inner wall of the bottom end of the mounting base.

Description

Technical Field

[0001] The present invention relates to the technical field of battery protection, and particularly to a leakage prevention and protection device for a UPS supporting battery. Background Art

[0002] The battery supporting a UPS (uninterruptible power supply) is one of the core components in the UPS system, mainly used for storing electric energy and providing backup power when the mains power fails. In the UPS system, secondary batteries not only serve as power storage and backup power sources but also need to have good safety and efficient power management. With the development of technology, secondary batteries such as lithium batteries and lead-acid batteries are widely used in the UPS system, especially lithium batteries, which have higher energy density and longer service life. In addition, the leakage prevention design of secondary batteries is of great significance to ensure that the batteries do not leak, expand or have other safety hazards during long-term charge and discharge processes.

[0003] The prior art document with the publication number CN209859986U provides a battery that prevents the outflow of inner liquid. By improving the traditional single-layer battery structure to a double-layer battery structure design, the leakage prevention performance of the device is effectively increased. And the connection between the outer shell and the outer cover and the connection between the inner shell and the inner cover adopt a combined design of leakage prevention grooves, leakage prevention bumps and sealing rings, further increasing the leakage prevention performance of the device. At the same time, a buffer flexible frame structure design is added between the outer shell and the inner shell, which not only does not affect the normal heat dissipation of the device but also can well protect the battery structure inside the inner shell when the device encounters an external impact, avoiding damage to the battery caused by external forces.

[0004] The prior art uses leakage prevention grooves, leakage prevention bumps and sealing rings to achieve leakage prevention in the connection between the inner shell and the inner cover. However, this technology is not convenient for leakage prevention treatment at the joint between the pole column and the battery shell. When leakage occurs at the pole column, the device cannot detect it in time, resulting in the electrolyte corroding the electrode terminal, causing short circuit or capacity reduction.

[0005] In summary, in the prior art, there is a lack of technology for leakage protection at the pole column of the battery. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies in the background art and propose a leakage prevention and protection device for a UPS supporting battery.

A lever is fixedly connected to the inner end of the locking block, and a spring is fixedly connected to the inner wall of the inner end of the locking block.

[0010] Preferably, an air storage chamber is formed on one side of the inner wall of the mounting base, and an air guide hole is formed through the upper inner wall of the air storage chamber. A liquid collection tank is formed at the top of the mounting base, and the bottom of the liquid collection tank is inclined. A groove is formed at the lowest point of the liquid collection tank, and a leakage sensor is installed in the groove.

[0011] Preferably, the leakage sealing mechanism at the electrode end includes a protective cover, the bottom end of which is bolted to the top end of the mounting base. A gas guide ring is fixedly connected to the inner wall of the top end of the protective cover, and an annular airbag is fixedly connected below the gas guide ring. The annular airbag abuts against the electrode interface of the battery casing. A stepped gas guide tube is fixedly connected to one end of the gas guide ring, and the outer wall of the stepped gas guide tube is movably inserted into the inner wall of the gas guide hole.

[0012] Preferably, the outer wall of the inflation frame is slidably fitted with the inner wall of the air storage chamber, a second spring is fixedly connected to the upper part of both ends of the inflation frame, the other end of the second spring is fixedly connected to the inner wall of the air storage chamber, and a T-shaped rod is fixedly connected to the middle of the inflation frame, the T-shaped rod is slidably fitted through the inner wall of the air storage chamber.

[0013] Preferably, the transmission mechanism includes a motor, which is fixedly connected to the inner wall of the mounting base. A threaded rod is fixedly connected to the output end of the motor, and a transmission ring is threadedly connected to the outer wall of the threaded rod. The outer wall of the transmission ring is slidably fitted with the inner wall of the mounting base, and a pushing hole is opened at one end of the transmission ring. The pushing hole is slidably fitted with the outer wall of the T-shaped rod.

[0014] Preferably, the automatic terminal separation mechanism includes a push ring, one end of which is fixedly connected to a guide rod. The bottom end of the guide rod extends through the outer wall of the mounting base and into the interior, where it is fixedly connected to a transmission ring. A pressure sleeve is provided above the push ring, and the pressure sleeve is fitted onto the positive and negative terminals of the battery casing. Threaded heads are fixedly connected to the top ends of both sides of the push ring. The two ends of the pressure sleeve are slidably fitted with the outer wall of the threaded head. A clamping nut is threadedly connected to the top end of the threaded head, and the bottom end of the clamping nut abuts against the two ends of the pressure sleeve.

[0015] Preferably, the top of the push plate is fixedly connected with a plurality of sliding rods in a ring structure. The outer wall of the sliding rod is slidably engaged with the inner wall of the bottom end of the mounting base. A spring is fixedly connected between the top of the sliding rod and the inner wall of the bottom end of the mounting base. The bottom end of the push plate is in movable contact with the inner wall of the bottom end of the mounting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting a leakage sealing mechanism at the terminal post of the battery casing, when leakage is detected at the joint between the terminal post and the battery casing, the transmission mechanism can drive the inflation frame to move upward, thereby inflating the annular airbag. The annular airbag then presses against the joint between the terminal post and the battery casing, thus sealing the leak point in time, completely cutting off the channel for liquid leakage, preventing further diffusion of electrolyte, and protecting the equipment and environment from corrosion. At the same time, the protective cover in the terminal post leakage sealing mechanism can block the joint between the terminal post and the battery casing, effectively preventing external water sources and moisture from directly contacting the leakage sensor, preventing false alarms or sensor damage, and ensuring the accuracy and effectiveness of the leakage sensor.

[0018] 2. By setting up an automatic terminal separation mechanism, when leakage occurs at the terminal post, the transmission mechanism drives the inflation frame to inflate and plug the leak, while the automatic terminal separation mechanism separates the terminal post from the terminal post. This can promptly cut off the electrical connection between the battery and the UPS, preventing leakage from causing short circuits or other electrical faults to the battery and electrical equipment, thereby protecting the equipment and effectively improving the safety and reliability of the UPS battery system.

[0019] 3. By providing a liquid collection groove with an inclined bottom at the top of the mounting base near the joint between the terminal and the battery casing, the sensitivity of leakage detection is improved when the leakage amount is small, ensuring early detection of leakage problems and preventing further spread of leakage. At the same time, the push plate at the bottom of the mounting base can push it out of the mounting groove when the mounting base is removed, making it easy to expose the terminal for inspection. This not only improves the convenience of operation, but also reduces the probability of human error. Attached Figure Description

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The UPS battery leakage protection device shown includes a battery casing 1. A mounting base 2 is movably connected to the positive and negative terminals of the battery casing 1. A terminal leakage sealing mechanism 3 is fixedly installed on the top of the mounting base 2. An inflation frame 4 for automatically inflating the terminal leakage sealing mechanism 3 is slidably fitted on the inner wall of the mounting base 2. A transmission mechanism 5 is fixedly connected to the inner wall of the mounting base 2. An automatic terminal separation mechanism 6 is provided above the mounting base 2. A push plate 7 is provided on the inner wall of the bottom end of the mounting base 2.

[0031] like Figure 3 As shown, the battery casing 1 has mounting grooves 101 at both the positive and negative terminals. A positioning rod 102 is fixedly connected to the inner wall of one side of the mounting groove 101, and slots 103 are provided on both sides of the inner wall of the mounting groove 101.

[0032] The mounting slot 101 provides a precise installation reference for the mounting base 2, and the positioning rod 102 realizes the circumferential positioning of the mounting base 2 to avoid misalignment of the wiring terminals caused by rotation after installation; the slot 103 cooperates with the locking block 203 to achieve quick locking and fixing without bolts, making disassembly and assembly convenient.

[0033] like Figure 4As shown, the mounting base 2 has a circular structure. A sealing gasket is provided on the inner wall of the mounting base 2. The outer wall of the mounting base 2 is movably inserted into the inner wall of the mounting groove 101. A positioning hole 201 is provided through the side of the mounting base 2 facing the positioning rod 102. The inner wall of the positioning hole 201 is movably inserted into the outer wall of the positioning rod 102. Both outer walls of the mounting base 2 have locking slots 202. Locking blocks 203 are slidably fitted into the inner walls of the locking slots 202. A slope is provided at the bottom of the outer end of the locking block 203. The outer end of the locking block 203 is movably locked into the inner wall of the locking slot 103. A lever 204 is fixedly connected to the inner end of the locking block 203. A spring 205 is fixedly connected to the inner wall of the inner end of the locking block 203. The other end of the spring 205 is fixedly connected to the inner wall of the locking slot 103. The sealing gasket ensures the seal between the inner wall of the mounting base 2 and the electrode post, ensuring that any leakage flows accurately into the collection tank 208.

[0034] Mounting base 2 is made of ABS engineering plastic material that is resistant to electrolyte corrosion, and the sealing gasket is made of fluororubber material, which has excellent acid resistance and temperature resistance, effectively preventing leakage from the gap between the electrode post and mounting base 2; the outer end of the locking block 203 is designed with a bevel to facilitate automatic sliding into the locking slot 103 during installation, and the spring 205 provides continuous locking force. When disassembling, it is only necessary to move the lever 204 to unlock, making the operation convenient.

[0035] An air storage chamber 206 is provided on one side of the inner wall of the mounting base 2. An air guide hole 207 is provided through the upper inner wall of the air storage chamber 206. A liquid collection tank 208 is provided at the top of the mounting base 2. The bottom of the liquid collection tank 208 is set with an inclined structure. A groove is provided at the lowest point of the liquid collection tank 208. A leakage sensor is installed in the groove.

[0036] The air storage chamber 206 provides movement space for the inflation frame 4, and the internal pre-stored dry compressed air pressure can meet the complete inflation and sealing requirements of the annular airbag 303; the inner wall of the air guide hole 207 is equipped with a sealing ring, which works with the stepped air guide tube 304 to achieve air path sealing and prevent gas leakage; the liquid collection tank 208 is inclined, which can guide the trace amount of leaked liquid to flow quickly to the lowest groove, ensuring that the leakage sensor can trigger the alarm at the initial stage of leakage and improve the monitoring sensitivity; the leakage sensor adopts the photoelectric or capacitive principle, is resistant to electrolyte corrosion, has a fast response time, and can transmit the leakage signal to the UPS monitoring system in real time.

[0037] like Figure 5 As shown, the terminal leakage sealing mechanism 3 includes a protective cover 301. The bottom end of the protective cover 301 is bolted to the top end of the mounting base 2. A venting ring 302 is fixedly connected to the inner wall of the top end of the protective cover 301. An annular airbag 303 is fixedly connected below the venting ring 302. The annular airbag 303 abuts against the terminal interface of the battery casing 1. A stepped venting pipe 304 is fixedly connected to one end of the venting ring 302. The outer wall of the stepped venting pipe 304 is movably inserted into the inner wall of the vent hole 207. The stepped venting pipe 304 improves the sealing performance.

[0038] The protective cover 301 can block dust and moisture, preventing the leakage sensor from being falsely triggered; the air guide ring 302 is made of aluminum alloy and evenly distributes airflow to the annular airbag 303; the annular airbag 303 is made of acid-resistant butyl rubber, which can fit tightly against the joint between the electrode post and the outer shell after inflation, sealing the leak point and preventing electrolyte leakage; the stepped air guide tube 304 adopts a multi-step structure, forming multiple seals with the inner wall of the air guide hole 207 to prevent gas leakage during inflation and ensure that the annular airbag 303 expands into place quickly.

[0039] By setting a terminal leakage sealing mechanism 3 at the terminal of the battery casing 1, when leakage is detected at the joint between the terminal and the battery casing 1, the transmission mechanism 5 can drive the inflation frame 4 to move upward, thereby inflating the annular airbag 303. The annular airbag 303 then presses against the joint between the terminal and the battery casing 1, thus sealing the leak point in time, completely cutting off the channel for liquid leakage, preventing further diffusion of electrolyte, and protecting the equipment and environment from corrosion. At the same time, the protective cover 301 in the terminal leakage sealing mechanism 3 can block the joint between the terminal and the battery casing 1, effectively preventing external water and moisture from directly contacting the leakage sensor, preventing false alarms or sensor damage, and ensuring the accuracy and effectiveness of the leakage sensor.

[0040] like Figure 4 As shown, the outer wall of the inflation frame 4 is slidably fitted with the inner wall of the air storage chamber 206. Springs 401 are fixedly connected to the upper ends of both ends of the inflation frame 4, with the other end of each spring 401 fixedly connected to the inner wall of the air storage chamber 206. A T-shaped rod 402 is fixedly connected to the middle of the inflation frame 4, and the T-shaped rod 402 slides through the inner wall of the air storage chamber 206. Springs 401 enable the inflation frame 4 to automatically move downwards and reset.

[0041] The air frame 4 is made of hard plastic and has a sealing gasket on its surface; the spring 401 is made of stainless steel and has stable elasticity. When the air frame 4 is pulled in its natural state, it is at the bottom of the air storage chamber 206 to avoid accidental inflation.

[0042] like Figure 6 As shown, the transmission mechanism 5 includes a motor 501, which is fixedly connected to the inner wall of the mounting base 2. A threaded rod 502 is fixedly connected to the output end of the motor 501. A transmission ring 503 is threadedly connected to the outer wall of the threaded rod 502. The outer wall of the transmission ring 503 is slidably fitted with the inner wall of the mounting base 2. A pushing hole 504 is opened at one end of the transmission ring 503, which is slidably fitted with the outer wall of the T-shaped rod 402. The transmission ring 503 can drive the T-shaped rod 402 to move upward.

[0043] Motor 501 is a miniature DC servo motor powered by a UPS system. It has a fast response speed and can start immediately after a leakage signal is triggered.

[0044] like Figure 7 As shown, the automatic terminal separation mechanism 6 includes a push-wire ring 601. A guide rod 602 is fixedly connected to one end of the push-wire ring 601. The bottom end of the guide rod 602 extends through the outer wall of the mounting base 2 and is fixedly connected to the transmission ring 503. A clamping sleeve 603 is positioned above the push-wire ring 601, fitting onto the positive and negative terminals of the battery casing 1. Threaded heads 604 are fixedly connected to the top ends of both sides of the push-wire ring 601. The two ends of the clamping sleeve 603 slide against the outer wall of the threaded head 604. A clamping nut 605 is threadedly connected to the top of the threaded head 604, and the bottom end of the clamping nut 605 abuts against the two ends of the clamping sleeve 603. The clamping sleeve 603 can press the terminal onto the terminal. The push-wire ring 601 can push the terminal away in case of leakage.

[0045] The push ring 601 and the transmission ring 503 are linked by the guide rod 602. While sealing the leakage, they simultaneously push the terminal blocker away from the pole to achieve electrical separation and avoid electrical faults such as short circuits and arcing caused by leakage. The clamping sleeve 603 is made of copper and has good conductivity. The clamping nut 605 can firmly clamp the terminal block onto the pole to ensure stable electrical connection. When disassembling, the terminal block can be removed simply by loosening the clamping nut 605. The threaded head 604 is integrally formed with the push ring 601, with a stable structure that can withstand the pulling force of the terminal block and prevent breakage during separation.

[0046] like Figure 8 As shown, the top of the push plate 7 is fixedly connected with multiple sliding rods 701 in a ring structure. The outer wall of the sliding rod 701 is slidably engaged with the inner wall of the bottom end of the mounting base 2. A spring 702 is fixedly connected between the top of the sliding rod 701 and the inner wall of the bottom end of the mounting base 2. The bottom end of the push plate 7 is in movable contact with the inner wall of the bottom end of the mounting groove 101.

[0047] The push plate 7 is made of acid-resistant plastic and is coaxially set with the mounting base 2; the spring 3 702 is a stainless steel spring with moderate elasticity. When the mounting base 2 is engaged in the mounting groove 101, the spring 3 702 is compressed. After disassembly and unlocking, the spring 3 702 pushes the push plate 7 down and pushes the mounting base 2 out of the mounting groove 101, making it easier to expose the pole for maintenance.

[0048] Working principle: Align the mounting base 2 with the mounting groove 101 at the terminal of the battery casing 1, so that the positioning hole 201 fits into the positioning rod 102, press the mounting base 2 down, the outer end of the locking block 203 is squeezed by the inner wall of the mounting groove 101, the compression spring 205 slides into the locking block groove 202, when the locking block 203 moves to the position of the locking groove 103, the spring 205 pushes the locking block 203 into the locking groove 103, and the mounting base 2 is fixed; at this time, the push plate 7 is squeezed by the bottom end of the mounting groove 101, the spring 702 is compressed, the sealing gasket of the inner wall of the mounting base 2 fits tightly with the terminal, blocking the leakage gap; place the terminal on the terminal, put on the wire clamping sleeve 603, tighten the clamping nut 605, and complete the electrical connection.

[0049] When the battery is charging and discharging normally, the mounting base 2 is in close contact with the terminal post, there is no leakage in the liquid collection tank 208, and the leakage sensor has no signal output. When leakage occurs at the joint between the terminal post and the battery casing 1, the electrolyte flows into the liquid collection tank 208 along the joint of the terminal post. Under the guidance of the inclined structure, it quickly gathers to the lowest groove, triggering the leakage sensor. The sensor transmits the leakage signal to the UPS monitoring system, and at the same time starts the motor 501 of the transmission mechanism 5. The motor 501 drives the threaded rod 502 to rotate, driving the transmission ring 503 to slide upward along the inner wall of the mounting base 2.

[0050] The transmission ring 503 drives the T-shaped rod 402 to move upward through the push hole 504, which in turn pushes the inflation frame 4 to slide upward along the air storage chamber 206, compressing the air in the air storage chamber 206. The air enters the annular air bag 303 through the air guide hole 207, the stepped air guide pipe 304, and the air guide ring 302. The annular air bag 303 expands rapidly, tightly fitting the joint between the electrode post and the outer shell, sealing the leak point and preventing the electrolyte from leaking out.

[0051] As the transmission ring 503 slides upward, the guide rod 602 drives the pusher ring 601 to move upward. The pusher ring 601 pushes the pressure sleeve 603 and the terminal block upward, causing the terminal block to separate from the pole, cutting off the electrical connection between the battery and the UPS, and preventing leakage from causing short circuits, arcs and other electrical faults.

[0052] After the leak was dealt with, the UPS system issued a maintenance prompt. The staff moved the lever 204 to disengage the locking block 203 from the locking slot 103. The spring 3 702 pushed the push plate 7 down, pushing the mounting base 2 out of the mounting slot 101, exposing the pole and the leak point for cleaning and maintenance. After the maintenance was completed, the reverse start motor 501 was started, which drove the threaded rod 502 to reverse. The transmission ring 503 moved down, and the spring 2 401 pulled the inflation frame 4 down. The gas in the annular air bag 303 was discharged and contracted, and the push ring 601 was reset. The wiring terminals and mounting base 2 were reinstalled, the device was reset, and normal operation was restored.
