Description

Technical Field

[0001] This application relates to the technical field of airtight detection of battery boxes, and more particularly to a water immersion detection tooling for energy storage battery boxes. Background Art

[0002] The sealing of the battery box is a key measure to ensure the safety and reliability of power batteries for electric vehicles. In new energy vehicles, as the power source, the performance and safety of the power battery are directly related to the safety of the whole vehicle.

[0003] In the related art, the water immersion detection tooling for energy storage battery boxes seals all the openings of the energy storage battery box, then immerses the sealed energy storage battery box in water, and finally applies air pressure to the sealed energy storage battery box. Under the pressure-holding state, it observes whether there is an air leakage point when the box is immersed in water. Currently, before the energy storage battery box enters the water, it is necessary to position the box on the tooling, and then seal the open end at the bottom of the box and the holes on the side. The positioning method is: applying a thrust to the side of the box to make the box abut against the positioning block; the sealing method is: applying a pressure to the top of the box to make the bottom end of the box press on the sealing ring to achieve sealing, and the holes on the side are sealed by applying a pressure to the plugging structure to make the plugging structure press on the holes on the side of the box. However, this kind of positioning and plugging method requires multi-directional and multi-point force application. First, if separate cylinders are used for driving, the air circuit mechanism is complex. Therefore, how to simplify the driving structure becomes a technical problem to be solved. Second, usually, if the cylinder is immersed in water along with the box, the requirements for the cylinder will also increase, and a waterproof cylinder needs to be used. If it is considered that the cylinder does not enter the water, its transmission structure will also increase. Therefore, on the premise of simplifying the driving, considering that the driving element does not enter the water also becomes a technical problem to be solved. Summary of the Invention

[0019] The beneficial effects of this application are as follows: During use, start the cable tensioning force application mechanism. The cable tensioning force application mechanism gradually tightens. First, the cable tensioning force application mechanism drives the surrounding positioning mechanism and the side hole plugging mechanism. The surrounding positioning mechanism pushes the energy storage battery box for positioning. At the same time, the side hole plugging mechanism presses tightly around the side holes of the energy storage battery box for plugging. Subsequently, the cable tensioning force application mechanism drives the top surrounding pressing mechanism, and the top surrounding pressing mechanism presses down tightly on the four surrounding sides of the top of the energy storage battery box to achieve the sealing of the lower opening of the energy storage battery box. Finally, the lifting immersion detection mechanism drives the energy storage battery box to be immersed in water, applies air pressure to the inside of the energy storage battery box, and observes whether there are air leakage points when the energy storage battery box is immersed in water under the pressure maintaining state. If there is no air leakage after a specified time, the lifting immersion detection mechanism drives the energy storage battery box to rise out of the water surface, and releases the tension of the cable tensioning force application mechanism on the surrounding positioning mechanism, the side hole plugging mechanism, and the top surrounding pressing mechanism. The surrounding positioning mechanism, the side hole plugging mechanism, and the top surrounding pressing mechanism return under the action of elastic force to detect the next energy storage battery box. When the lifting immersion detection mechanism drives the energy storage battery box to be immersed in water, the driving part of the cable tensioning force application mechanism is higher than the water surface in the lifting immersion detection mechanism, so that the driving element does not enter the water. This energy storage battery box immersion detection tooling uses the drive of a single cable tensioning force application mechanism to apply force and seal the energy storage battery box in multiple directions and at multiple points, and simplifies the circuit or air circuit by using mechanical mechanisms, which is convenient for inspection and maintenance. On the premise of taking into account the simplification of the drive, the driving element does not enter the water, reducing the selection requirements for the driving element.

[0041] Please refer to Figure 1The energy storage battery box is placed on the lifting position in the lifting water immersion detection mechanism 100, the surrounding positioning mechanism 200 is arranged on the periphery of the upper side of the lifting position in the lifting water immersion detection mechanism 100, the side hole blocking mechanism 300 is installed at the front end of the lifting position in the lifting water immersion detection mechanism 100, the top surrounding clamping mechanism 400 is connected to the surrounding of the upper side of the lifting position in the lifting water immersion detection mechanism 100, the driving part of the steel cable tensioning and forcing mechanism 500 is higher than the top of the lifting water immersion detection mechanism 100, the steel cable tensioning and forcing mechanism 500 tightens the surrounding positioning mechanism 200 and the side hole blocking mechanism 300 in turn, the surrounding positioning mechanism 200 pushes the energy storage battery box to position, the side hole blocking mechanism 300 presses the periphery of the side hole of the energy storage battery box to block, and the steel cable tensioning and forcing mechanism 500 pulls the top surrounding clamping mechanism 400 to swing downward and press the top of the energy storage battery box. When in use, the steel cable tensioning force applying mechanism 500 is started, and the steel cable tensioning force applying mechanism 500 is gradually tightened. The steel cable tensioning force applying mechanism 500 first drives the surrounding positioning mechanism 200 and the side hole sealing mechanism 300. The surrounding positioning mechanism 200 pushes the energy storage battery case to be positioned. At the same time, the side hole sealing mechanism 300 presses the side holes of the energy storage battery case to seal. Thereafter, the steel cable tensioning force applying mechanism 500 drives the top surrounding pressing mechanism 400. The top surrounding pressing mechanism 400 presses the top surrounding of the energy storage battery case downward to seal the lower end opening of the energy storage battery case. Finally, the lifting water immersion detection mechanism 100 drives the energy storage battery case to be immersed in water, applies air pressure to the inside of the energy storage battery case, and observes whether there is a leak in the energy storage battery case when it is immersed in water under the pressure maintaining state. If there is no leak after a certain period of time, the lifting water immersion detection mechanism 100 drives the energy storage battery case The body rises and protrudes out of the water surface, and the tension of the surrounding positioning mechanism 200, the side hole blocking mechanism 300 and the top surrounding pressing mechanism 400 by the steel cable tensioning and forcing mechanism 500 is released.

When positioning the energy storage battery box, the energy storage battery box is placed between the side positioning blocks 210, the side pressing members 220, the end positioning blocks 230 and the end pressing members 240. The side and front-rear positions of the energy storage battery box are determined based on the side positioning blocks 210 and the end positioning blocks 230. The cable tensioning force application mechanism 500 applies pressure to the side pressing members 220 and the end pressing members 240. The side pressing member 220 pushes the energy storage battery box towards the side positioning block 210. At the same time, the end pressing member 240 pushes the energy storage battery box towards the end positioning block 230, thereby positioning the position of the energy storage battery box.

[0044] Please refer to Figures 1 to 5, the side pushing member 220 includes a first mounting seat 221 and a side pushing rod portion 222. The first mounting seat 221 is fixedly connected to the side of the lifting position in the lifting immersion detection mechanism 100. In this embodiment, the first mounting seat 221 is fixedly connected to the side of the lifting platform 140. The side pushing rod portion 222 is slidably connected to the first mounting seat 221.

The end pushing member 240 includes a second mounting seat 241 and an end pushing rod portion 242. The second mounting seat 241 is fixedly connected to the end of the lifting position in the lifting immersion detection mechanism 100. Specifically, the second mounting seat 241 is fixedly connected to the end of the lifting platform 140. The end pushing rod portion 242 is slidably connected to the second mounting seat 241. The cable tensioning force application mechanism 500 drives the end pushing rod portion 242 to press against the side surface of the end of the energy storage battery box body. The cable tensioning force application mechanism 500 applies pressure to the side pushing rod portion 222 and the end pushing rod portion 242. The side pushing rod portion 222 slides along the first mounting seat 221, and the end pushing rod portion 242 slides along the second mounting seat 241. The side pushing rod portion 222 and the end pushing rod portion 242 drive the energy storage battery box body for positioning.

[0045] Please refer to Figures 1 to 5, the side pushing rod part 222 includes a second force-applying plate 2221, a fourth guide ring 2222, a second sliding rod 2223, a first pushing plate 2224 and a second spring 2225.

The second spring 2225 is sleeved on the second sliding rod 2223. Both ends of the second spring 2225 press against the first mounting seat 221 and the second force-applying plate 2221 respectively. The end pushing rod part 242 and the side pushing rod part 222 have the same structure. The connection between the side pushing rod part 222 and the first mounting seat 221 is the same as the connection between the end pushing rod part 242 and the second mounting seat 241. The cable tensioning force-applying mechanism 500 can press the fourth guide ring 2222 towards the energy storage battery box body. The cable tensioning force-applying mechanism 500 applies pressure to the second force-applying plate 2221 through the fourth guide ring 2222. The second force-applying plate 2221 drives the second sliding rod 2223 to slide along the first mounting seat 221. The second force-applying plate 2221 drives the second spring 2225 to shorten. The elastic force of the second spring 2225 increases. The second sliding rod 2223 drives the first pushing plate 2224. The first pushing plate 2224 drives the energy storage battery box body to be pressed against the side positioning block 210. The principle that the end pushing rod part 242 pushes the energy storage battery box body to be pressed against the end positioning block 230 is the same as the principle that the side pushing rod part 222 drives the energy storage battery box body to be pressed against the side positioning block 210.

[0046] Please refer to Figures 1 to 6, the side hole plugging mechanism 300 includes a third mounting seat 310, a first force application plate 320, a double-layer elastic sealing plugging member 330, a first sliding rod 340, a positioning nut 350, a first spring 360, and a first guide ring 370. The third mounting seat 310 is fixedly connected to the lifting position inside the lifting immersion detection mechanism 100. Specifically, the third mounting seat 310 is fixedly connected to the upper side of the lifting platform 140. The third mounting seat 310 is located on one side of the energy storage battery box body with side holes. A plurality of double-layer elastic sealing plugging members 330 are provided. Each double-layer elastic sealing plugging member 330 is connected to the first force application plate 320 through a plurality of first sliding rods 340. The first sliding rods 340 slidably penetrate through the third mounting seat 310. The positioning nut 350 is threadedly sleeved on one of the first sliding rods 340. The third mounting seat 310 can block the positioning nut 350. The first spring 360 is sleeved on the remaining first sliding rods 340. The first spring 360 presses against the first force application plate 320 and the third mounting seat 310 respectively. The plurality of double-layer elastic sealing plugging members 330 press and seal the side holes of the energy storage battery box body. The first guide ring 370 is fixedly connected to the side of the first force application plate 320 away from the first sliding rods 340. The cable tensioning force application mechanism 500 can press the first guide ring 370 towards the energy storage battery box body. The cable tensioning force application mechanism 500 applies pressure to the first force application plate 320 through the first guide ring 370. The first force application plate 320 drives the first sliding rods 340 to slide along the third mounting seat 310. The first force application plate 320 drives the first spring 360 to shorten. The elastic force of the first spring 360 increases. The first sliding rods 340 drive the double-layer elastic sealing plugging members 330. The double-layer elastic sealing plugging members 330 are gradually pressed against the side holes of the energy storage battery box body for plugging. Thereafter, buffering occurs inside the double-layer elastic sealing plugging members 330 until the positioning nut 350 abuts against the third mounting seat 310. The pressure of the double-layer elastic sealing plugging members 330 on the energy storage battery box body is adjusted through the positioning nut 350, so that the pressure of the double-layer elastic sealing plugging members 330 on the energy storage battery box body is less than the pressure of the end pushing rod portion 242 on the energy storage battery box body, so that the end pushing rod portion 242 can push the energy storage battery box body towards the end positioning block 230.

[0047] Please refer to Figures 1 to 6, the double-layer elastic sealing plug 330 includes a mounting plate 331, a buffer spring 332, and a sealing plate 333. The buffer spring 332 is disposed between the mounting plate 331 and the sealing plate 333. The mounting plate 331 is fixedly connected to the top end of the first sliding rod 340, and the sealing plate 333 presses and seals the side hole of the energy storage battery box. When buffering occurs in the double-layer elastic sealing plug 330, the sealing plate 333 first seals the side hole of the energy storage battery box. Subsequently, the mounting plate 331 drives the buffer spring 332 to be compressed, the elastic force of the buffer spring 332 increases, and the pressure of the sealing plate 333 on the side hole of the energy storage battery box increases. By adjusting the position of the positioning nut 350, the degree of compression of the buffer spring 332 is adjusted, thereby adjusting the pressure of the sealing plate 333 on the side hole of the energy storage battery box.

The third guide ring 423 is fixedly sleeved on the rear end of the second return swing frame 422. The rear-end top pressing member 430 has the same structure as the left-side top pressing member 420. The rear-end top pressing member 430 is arranged at the rear end of the lifting position in the lifting immersion detection mechanism 100. Specifically, the rear-end top pressing member 430 is arranged at the rear end of the lifting platform 140. The right-side pressing member 440 includes a third hinge seat 441, a third return swing frame 442 and a guiding part 443. The third hinge seat 441 is fixedly connected to both ends of the right side of the lifting position in the lifting immersion detection mechanism 100. It should be noted that the third hinge seat 441 is fixedly connected to both ends of the right side of the lifting platform 140. The connection between the third return swing frame 442 and the third hinge seat 441 is the same as the connection between the first return swing frame 412 and the first hinge seat 411. The guiding part 443 is fixedly sleeved on the rear end of the third return swing frame 442. The steel cable tensioning force application mechanism 500 can pull the guiding part 443, the second guide ring 413, the third guide ring 423 of the left-side top pressing member 420 and the third guide ring 423 of the rear-end top pressing member 430 upward. The front end of the first return swing frame 412, the front ends of the second return swing frames 422 of the rear-end top pressing member 430, the front ends of the second return swing frames 422 of the left-side top pressing member 420 and the front end of the third return swing frame 442 respectively press the front, rear, left and right four sides of the top of the energy storage battery box body.The cable tensioning force application mechanism 500 pulls up the second guide ring 413, the third guide ring 423 of the left side top pressing member 420, the third guide ring 423 of the rear end top pressing member 430, and the guiding portion 443. The second guide ring 413, the third guide ring 423 of the left side top pressing member 420, the third guide ring 423 of the rear end top pressing member 430, and the guiding portion 443 respectively drive the rear ends of the first return swing frame 412, the second return swing frame 422 of the left side top pressing member 420, the second return swing frame 422 of the rear end top pressing member 430, and the third return swing frame 442. The first return swing frame 412 swings around the first hinge seat 411, the second return swing frame 422 of the left side top pressing member 420 swings around the second hinge seat 421, the second return swing frame 422 of the rear end top pressing member 430 swings around the second hinge seat 421, the third return swing frame 442 swings around the third hinge seat 441.

[0050] Please refer to Figures 1 to 10, the first return swing frame 412 includes a swing frame 4121, ear plates 4122, torsion springs 4123, a pressing frame 4124 and a sliding cylinder 4125. The ear plates 4122 are fixedly connected to the lower side of the rear end of the swing frame 4121. The ear plates 4122 are hinged to the first hinge seat 411 through a pin shaft. The torsion springs 4123 are sleeved on the pin shaft. The two ends of the torsion springs 4123 are respectively connected to the ear plates 4122 and the first hinge seat 411. The elastic force of the torsion springs 4123 pushes the swing frame 4121 to swing backward. The sliding cylinder 4125 is fixedly connected to the front end of the swing frame 4121. The rear end of the pressing frame 4124 is slidably connected to the sliding cylinder 4125. The front end of the pressing frame 4124 presses against the top of the energy storage battery box body. The second guide ring 413 is fixedly connected to the rear end of the swing frame 4121. The steel cable tensioning force application mechanism 500 can pull up the second guide ring 413. The structures of the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442 are the same. The connections of the first hinge seat 411, the first return swing frame 412 and the second guide ring 413 are the same as the connections of the second hinge seat 421, the second return swing frame 422 and the third guide ring 423, and the connections of the third hinge seat 441, the third return swing frame 442 and the guiding part 443. When the first return swing frame 412 presses against the top of the energy storage battery box body, the second guide ring 413 pulls up the rear end of the swing frame 4121. The ear plates 4122 of the swing frame 4121 swing around the first hinge seat 411 through the pin shaft. The elastic force of the torsion springs 4123 increases. The swing frame 4121 drives the sliding cylinder 4125 to swing downward. The pressing frame 4124 extends along the sliding cylinder 4125 under the action of gravity. The pressing frame 4124 extends above the top of the energy storage battery box body, and then the pressing frame 4124 presses against the top of the energy storage battery box body. When the tension of the steel cable tensioning force application mechanism 500 on the second guide ring 413 is released, the swing frame 4121 swings upward at the front end under the action of the elastic force of the torsion springs 4123. The pressing frame 4124 first leaves the top of the energy storage battery box body. When the angle of the front end of the swing frame 4121 swings to the upper side, the pressing frame 4124 retracts along the sliding cylinder 4125 under the action of gravity, so that the pressing frame 4124 leaves above the top of the energy storage battery box body, reducing the situation that the pressing frame 4124 blocks the energy storage battery box body when the energy storage battery box body is replaced. The principles of the second return swing frame 422 and the third return swing frame 442 pressing against the top of the energy storage battery box body are the same as the principle of the first return swing frame 412 pressing against the top of the energy storage battery box body, so as to realize the pressing around the top of the energy storage battery box body.

[0051] Please refer to Figures 1 to 11, the cable tensioning force application mechanism 500 includes a double-layer guide frame 510, an upper-layer guide frame 520, a base frame 530, a driving winch 540, a first fixed pulley 550, a second fixed pulley 560 and a cable member 570. The driving winch 540 is the driving part of the cable tensioning force application mechanism 500. Both the double-layer guide frame 510 and the upper-layer guide frame 520 are provided with four. The four double-layer guide frames 510 and the four upper-layer guide frames 520 are respectively arranged at the four corners of the lifting position in the lifting immersion detection mechanism 100. It should be noted that the four double-layer guide frames 510 and the four upper-layer guide frames 520 are respectively arranged at the four corners of the lifting platform 140. Both ends of the base frame 530 are fixedly connected to the tops of the double-layer guide frame 510 and the upper-layer guide frame 520 at the front and rear ends on the right side of the lifting position in the lifting immersion detection mechanism 100. Specifically, both ends of the base frame 530 are fixedly connected to the tops of the double-layer guide frame 510 and the upper-layer guide frame 520 at the front and rear ends on the right side of the lifting platform 140. The driving winch 540 is fixedly connected to the base frame 530. Both the first fixed pulley 550 and the second fixed pulley 560 are arranged at the lifting position in the lifting immersion detection mechanism 100. In this embodiment, both the first fixed pulley 550 and the second fixed pulley 560 are arranged on the lifting platform 140. The first fixed pulley 550 is located below the driving winch 540. The second fixed pulley 560 is close to the double-layer guide frame 510 at the rear end on the right side of the lifting position in the lifting immersion detection mechanism 100. Specifically, when setting, the second fixed pulley 560 is close to the double-layer guide frame 510 at the rear end on the right side of the lifting platform 140. One end of the cable member 570 is connected to the driving winch 540. The other end of the cable member 570 is arranged in two layers up and down. The other end of the cable member 570 first bypasses the first fixed pulley 550, and then the cable member 570 bypasses the lower ends of the double-layer guide frames 510 on the right side of the front end, the left side of the front end, the left side of the rear end, and the right side of the rear end to form the lower-layer arrangement of the cable member 570. When the cable member 570 bypasses between adjacent double-layer guide frames 510, the cable member 570 pushes the surrounding positioning mechanism 200 to position the energy storage battery box, and the cable member 570 pushes the side hole plugging mechanism 300 to seal the side holes of the energy storage battery box. After the cable member 570 bypasses the lower end of the double-layer guide frame 510 on the right side of the rear end, it bypasses the second fixed pulley 560. The cable member 570 passes through the front and rear ends under the base frame 530 after being redirected by the second fixed pulley 560. When the cable member 570 passes through the front and rear ends under the base frame 530, the cable member 570 passes through the guiding part 443, and then the cable member 570 passes through the upper ends of the double-layer guide frame 510 and the upper-layer guide frame 520 on the right side of the front end, the left side of the front end, and the left side of the rear end to form the upper-layer arrangement of the cable member 570. When the cable member 570 bypasses between adjacent upper-layer guide frames 520, the cable member 570 passes through the third guide ring 423, the third guide ring 423 of the left-side top pressing member 420, and the third guide ring 423 of the rear-end top pressing member 430, and finally the cable member 570 is fixed to the upper end of the upper-layer guide frame 520 on the right side of the rear end.When the cable tensioning force application mechanism 500 applies force to the surrounding positioning mechanism 200, the side hole plugging mechanism 300, and the top surrounding pressing mechanism 400, the driving winch 540 is started, and the driving winch 540 tightens the cable member 570. The cable member 570 is first redirected by the first fixed pulley 550. The cable member 570 is redirected through the lower ends of the four double-layer guide frames 510 to form the lower layer arrangement of the cable member 570. Through the redirection of the double-layer guide frame 510, the cable member 570 passes through the first guide ring 370, the fourth guide ring 2222 of the side pushing rod part 222, and the fourth guide ring 2222 of the end pushing rod part 242, thereby applying pressure to the first guide ring 370, the fourth guide ring 2222 of the side pushing rod part 222, and the fourth guide ring 2222 of the end pushing rod part 242. The lower layer arrangement of the cable member 570 is redirected by the second fixed pulley 560 and then passes through the front and rear ends of the lower side of the base frame 530. When the cable member 570 passes through the front and rear ends of the base frame 530, the cable member 570 passes through the guiding part 443. The cable member 570 is first blocked by the guiding part 443, so that the cable member 570 first applies pressure to the first guide ring 370, the fourth guide ring 2222 of the side pushing rod part 222, and the fourth guide ring 2222 of the end pushing rod part 242. When the applied pressure is greater than the resistance of the guiding part 443 to the cable member 570, the blocked part (step buffer block 572) of the cable member 570 crosses the guiding part 443. After the cable member 570 passes through the front end of the base frame 530, it passes through the upper ends of the four double-layer guide frames 510 and the four upper guide frames 520 to form the upper layer arrangement of the cable member 570. Through the redirection of the double-layer guide frame 510 and the upper guide frame 520, the cable member 570 passes through the second guide ring 413, the third guide ring 423 of the left side top pressing member 420, and the third guide ring 423 of the rear end top pressing member 430, thereby applying an upward pulling force to the second guide ring 413, the third guide ring 423 of the left side top pressing member 420, and the third guide ring 423 of the rear end top pressing member 430.

[0052] Please refer to Figures 1 to 13The base frame 530 includes a base plate 531 and a fixed guide ring 532. The base plate 531 is fixedly connected to the double-layer guide frame 510 and the top of the upper guide frame 520 at the front and rear ends of the right side of the lifting position in the lifting type immersion detection mechanism 100. The fixed guide ring 532 is fixedly connected to the front and rear ends of the lower side of the base plate 531. Specifically, the base plate 531 is fixedly connected to the double-layer guide frame 510 and the top of the upper guide frame 520 at the front and rear ends of the right side of the lifting platform 140. The steel cable member 570 includes a steel cable 571 and a step buffer block 572. The steel cable 571 passes through the fixed guide rings 532 at the front and rear ends of the base plate 531 after being redirected by the second fixed pulley 560. The step buffer block 572 is fixedly sleeved on the steel cable 571. The step buffer block 572 is located between the fixed guide rings 532 at the front and rear ends of the base plate 531. The guide portion 443 includes a guide block 4431, a mounting cylinder 4434 and a bumping ball 4435. The lower end of the guide block 4431 is fixedly sleeved on the third return position. At the rear end of the swing frame 442, an insertion hole 4432 is opened at the upper end of the guide block 4431, and guide grooves 4433 are set at both ends of the insertion hole 4432. The mounting tube 4434 is fixedly inserted around the insertion hole 4432 of the guide block 4431, and the bumper 4435 is inserted into the mounting tube 4434. One end of the bumper 4435 extends into the insertion hole 4432. The step buffer block 572 can push the end of the bumper 4435 to retract, and the step buffer block 572 can pass over the bumper 4435. The step buffer block 572 is first stopped by the bumping bead 4435 on the guide block 4431. When the force applied to the steel cable 571 is greater than the resistance of the bumping bead 4435 to the step buffer block 572, the step buffer block 572 compresses the bumping bead 4435, so that the step buffer block 572 passes through the through hole 4432 on the guide block 4431. The step buffer block 572 is guided by the guide groove 4433 before and after entering the through hole 4432, so that the step buffer block 572 can pass through the through hole 4432 easily. When the winch 540 is driven to tighten the steel cable 571, the step buffer block 572 passes through the insertion hole 4432 to reach the rear end of the guide block 4431. When the winch 540 is driven to release the steel cable 571, the steel cable 571 pulls the steel cable 571 under the elastic force of the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442, and the steel cable 571 drives the step buffer block 572 to pass back through the insertion hole 4432, so that the step buffer block 572 reaches the front end of the guide block 4431. When the steel cable member 570 passes through the front and rear ends of the base frame 530, the steel cable 571 successively hits the fixed guide ring 532 at the rear end and the front end of the base plate 531.

[0053] See also Figures 1 to 14, the double-layer guide frame 510 includes a double-layer guide rod 511, guide wheels 512, a first top guide ring 513 and a cable locking frame 514. The guide wheels 512 are fixedly sleeved on the lower end of the double-layer guide rod 511. The first top guide ring 513 is fixedly connected to the upper end of the double-layer guide rod 511. The cable locking frame 514 is fixedly connected to the upper and lower sides of the guide wheels 512.

The upper-layer guide frame 520 includes an upper-layer guide rod 521 and a second top guide ring 522. The second top guide ring 522 is fixedly connected to the upper-layer guide rod 521. The cable member 570 arranged in the upper layer passes through the first top guide ring 513 and the second top guide ring 522. When the cable member 570 in the lower layer is arranged, the cable 571 bypasses the guide wheels 512 at the lower ends of the four double-layer guide rods 511, and the cable locking frame 514 blocks the cable 571 on the guide wheels 512. In this way, the cable 571 arranged in the lower layer is redirected by the guide wheels 512 at the lower ends of the four double-layer guide rods 511. When the cable member 570 in the upper layer is arranged, the cable 571 bypasses the first top guide ring 513 of the double-layer guide rod 511 and the second top guide ring 522 of the upper-layer guide rod 521. In this way, the cable 571 arranged in the upper layer is redirected by the first top guide ring 513 of the four double-layer guide rods 511 and the second top guide ring 522 of the upper-layer guide rod 521.

[0054] Specifically, the working principle of the immersion detection tooling for the energy storage battery box: When in use, start the driving winch 540. The driving winch 540 tightens the steel cable 571. The steel cable 571 is redirected by the first fixed pulley 550 first, and then the steel cable 571 bypasses the guide wheels 512 at the lower ends of the four double-layer guide rods 511. The rope locking frame 514 blocks the steel cable 571 on the guide wheels 512. In this way, the steel cable 571 arranged in the lower layer is formed by redirecting through the guide wheels 512 at the lower ends of the four double-layer guide rods 511. The steel cable 571 arranged in the lower layer passes through the first guide ring 370, the fourth guide ring 2222 of the side push rod part 222, and the fourth guide ring 2222 of the end push rod part 242, so as to apply pressure to the first guide ring 370, the fourth guide ring 2222 of the side push rod part 222, and the fourth guide ring 2222 of the end push rod part 242. The fourth guide ring 2222 applies pressure to the second force application plate 2221. The second force application plate 2221 drives the second sliding rod 2223 to slide along the first mounting seat 221. The second force application plate 2221 drives the second spring 2225 to shorten, and the elastic force of the second spring 2225 increases. The second sliding rod 2223 drives the first push plate 2224, and the first push plate 2224 drives the energy storage battery box to be pressed tightly against the side positioning block 210. The principle that the end push rod part 242 pushes the energy storage battery box to be pressed tightly against the end positioning block 230 is the same as the principle that the side push rod part 222 drives the energy storage battery box to be pressed tightly against the side positioning block 210, realizing the positioning of the energy storage battery box. When the end push rod part 242 and the side push rod part 222 perform the positioning of the energy storage battery box, the stepped buffer block 572 is first blocked by the ball 4435 on the guide block 4431. Using the stepped buffer block 572 and the guide block 4431 as temporary support points, the positioning of the energy storage battery box is first carried out. When the force received by the steel cable 571 is greater than the resistance of the ball 4435 to the stepped buffer block 572, the stepped buffer block 572 compresses the ball 4435, so that the stepped buffer block 572 passes through the insertion hole 4432 on the guide block 4431, and the stepped buffer block 572 passes through the insertion hole 4432 to reach the rear end of the guide block 4431, and the supporting effect of the guide block 4431 on the stepped buffer block 572 is released.The lower layer arrangement of the cable 571 is redirected by the second fixed pulley 560, and then the cable 571 passes through the fixed guide rings 532 at the rear end and the front end of the base plate 531 in sequence. When the cable 571 passes through the fixed guide rings 532 at the rear end and the front end of the base plate 531, the cable 571 passes through the insertion hole 4432 of the guide block 4431. The cable 571 bypasses the first top guide ring 513 of the double-layer guide rod 511 and the second top guide ring 522 of the upper guide rod 521. In this way, the cable 571 of the upper layer arrangement is redirected through the first top guide ring 513 of the four double-layer guide rods 511 and the second top guide ring 522 of the upper guide rod 521. The cable 571 passes through the second guide ring 413, the third guide ring 423 of the left side top pressing member 420, and the third guide ring 423 of the rear end top pressing member 430. After the stepped buffer block 572 on the cable 571 crosses the insertion hole 4432 and reaches the rear end of the guide block 4431, the cable 571 applies an upward pulling force to the second guide ring 413, the third guide ring 423 of the left side top pressing member 420, and the third guide ring 423 of the rear end top pressing member 430. The second guide ring 413 pulls the rear end of the swing frame 4121 upward. The ear plate 4122 of the swing frame 4121 swings around the first hinge seat 411 through the pin shaft, and the elastic force of the torsion spring 4123 increases. The swing frame 4121 drives the sliding cylinder 4125 to swing downward. The pressing frame 4124 extends along the sliding cylinder 4125 under the action of gravity. The pressing frame 4124 extends above the top of the energy storage battery box body, and then the pressing frame 4124 presses the top of the energy storage battery box body. When the pulling force of the cable tensioning mechanism 500 on the second guide ring 413 is released, the swing frame 4121 swings upward at the front end under the action of the elastic force of the torsion spring 4123. The pressing frame 4124 first leaves the top of the energy storage battery box body. When the angle of the front end of the swing frame 4121 swings to the upper side, the pressing frame 4124 retracts along the sliding cylinder 4125 under the action of gravity, so that the pressing frame 4124 leaves above the top of the energy storage battery box body, reducing the situation that the pressing frame 4124 blocks the energy storage battery box body when the energy storage battery box body is replaced. The principle of the second return swing frame 422 and the third return swing frame 442 pressing the top of the energy storage battery box body is the same as that of the first return swing frame 412 pressing the top of the energy storage battery box body. In this way, the top of the energy storage battery box body is pressed around, and then the sealing of the lower end opening of the energy storage battery box body is realized.In the above process, the first guide ring 370 applies pressure to the first force plate 320, and the first force plate 320 drives the first slide bar 340 to slide along the third mounting seat 310. The first force plate 320 drives the first spring 360 to shorten, and the elastic force of the first spring 360 increases. The first slide bar 340 drives the double-layer elastic sealing plug 330, and the double-layer elastic sealing plug 330 gradually presses on the energy storage battery box and presses on the side hole of the energy storage battery box to seal. The sealing plate 333 first seals the side hole of the energy storage battery box. Thereafter, the mounting plate 331 drives the buffer spring 332 to be compressed, and the elastic force of the buffer spring 332 increases. The sealing plate 333 is pressed against the side hole of the energy storage battery box. The pressure on the side hole of the energy storage battery case increases, and the position of the positioning nut 350 is adjusted to achieve the degree of compression of the buffer spring 332, thereby adjusting the pressure of the sealing plate 333 on the side hole of the energy storage battery case to seal the side hole of the energy storage battery case until the positioning nut 350 is against the third mounting seat 310. The pressure of the double-layer elastic sealing plugging member 330 on the energy storage battery case is adjusted by the positioning nut 350, so that the pressure of the double-layer elastic sealing plugging member 330 on the energy storage battery case is less than the pressure of the end pushing rod 242 on the energy storage battery case, so that the end pushing rod 242 can push the energy storage battery case toward the end positioning block 230. The energy storage battery box water immersion detection tool adopts the drive of a single drive winch 540 to perform multi-directional and multi-point force sealing of the energy storage battery box, and adopts a mechanical mechanism to simplify the circuit or gas path, which is convenient for inspection and maintenance. Under the premise of taking into account the simplification of the drive, the drive winch 540 is raised by the double-layer guide frame 510 and the upper guide frame 520, so that the drive element does not enter the water, thereby reducing the selection requirements for the drive element. After the energy storage battery box rises with the lifting platform 140 and protrudes out of the water, the winch 540 is driven to release the steel cable 571, and the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442 automatically return to their original positions under the elastic force, releasing the pressure on the top of the energy storage battery box, and the side pushing rod 222, the end pushing rod 242 and the double-layer elastic sealing plugging component 330 return to their original positions under the elastic force. At the same time, the steel cable 571 is pulled by the elastic force of the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442, and the steel cable 571 drives the step buffer block 572 to pass back through the insertion hole 4432, so that the step buffer block 572 reaches the front end of the guide block 4431.
