[0070] Figure 2 The embodiment of the present invention provides Figure 1 The schematic diagram of the partially enlarged structure at A is as follows: Figure 2 As shown, the detection device further includes: a slide groove 7, a threaded rod 8, a sliding block 10, a camera acquisition instrument 11, a signal transceiver 12, a gas detection instrument 13, a buzzer warning light 14 and a connecting line 15.

[0071] The detection device further includes two drive components. The second drive component includes a drive motor 91 and a threaded rod 8. The drive motor 91 and the threaded rod 8 are fixedly connected. The threaded rod 8 is transmission-connected to the detection part.

[0072] Optionally, a first forward and reverse motor 9 is fixedly mounted on the upper end of the horizontal plate 5 , and a threaded rod 8 is fixedly connected to the lower end of the output shaft of the first forward and reverse motor 9 , and the threaded rod 8 extends downward and penetrates the horizontal plate 5 above.

[0073] Specifically, the first forward and reverse motor 9 is externally connected to a drive controller, which can stop and rotate the first forward and reverse motor 9 accordingly.

[0074] The second structural member includes a guide rail, the detection portion is arranged on the guide rail, and the detection portion can move relative to the guide rail in a direction parallel to the guide rail.

[0075] Optionally, the guide rail may be a slide groove 7, and the detection portion may be a detection and warning component.

[0076] Optionally, a slide groove 7 is provided on the inner end surface of the vertical plate 6, a sliding block 10 is movably provided in the inner cavity of the slide groove 7, and a detection and early warning component is installed on the inner end surface of the sliding block 10.

[0077] Specifically, the detection and early warning component will be connected to the external control room before use to complete a connection similar to a monitoring system.

[0078] The detection unit includes an image acquisition module, which is used to capture images of the target tank.

[0079] The detection unit also includes an alarm unit, which is used to issue an alarm after gas leakage and / or liquid leakage occurs in the target tank.

[0080] Optionally, the detection and warning component includes a video acquisition instrument 11 , a signal transceiver 12 , a gas detection instrument 13 , a buzzer warning light 14 and a connecting line 15 .

[0081] Specifically, a video capture instrument 11 is fixedly installed on the inner end surface of the sliding block 10, a signal transceiver 12 electrically connected to the video capture instrument 11 is fixedly installed on the upper end, and a buzzer warning light 14 is fixedly installed on the lower end of the video capture instrument 11. The buzzer warning light 14 can flash and make a sound.

[0082] For example, the video acquisition instrument 11 collects image information of the outer walls of the battery stack 1, the positive electrolyte storage tank 2, and the negative electrolyte storage tank 3, and then transmits it to the monitoring system for comparison through the signal transceiver 12. A judgment is made based on the comparison results. If there is a leakage, the signal transceiver 12 transmits the feedback information to the buzzer warning light 14 through the connecting line 15, causing it to flash and sound to alert the staff.

[0083] The detection unit further includes a gas detection module, which is used to detect whether gas leakage occurs in the target tank.

[0084] The detection unit further includes a transmission module, which is used to transmit images to the monitoring system and to receive liquid leakage results sent by the monitoring system.

[0085] More specifically, the left end of the signal transceiver 12 is provided with another connecting line 15 connected to the gas detection instrument 13 and the buzzer warning light 14 for transmitting electrical signals. Through image detection and gas detection, different tanks and pipes can be detected at the same time.

[0086] For example, the gas detection instrument 13 is mainly used to detect leaks at locations where the video capture instrument 11 cannot capture images. When a leak occurs at such a location, the gas detection instrument 13 detects the air mixed with the all-vanadium liquid. If a leak occurs, the gas detection instrument 13 transmits an electrical signal to the buzzer warning light 14 through the connecting line 15, causing it to flash and sound.

[0087] The detection portion is arranged on the mounting portion, and the detection portion and the mounting portion are movably connected, and the detection portion can move relative to the mounting portion along the axial direction of the target tank body.

[0088] Optionally, the threaded rod 8 passes through the sliding block 10 and is screwed therewith.

[0089] In this embodiment of the utility model, the forward and reverse rotation of the first forward and reverse motor 9 drives the threaded rod 8 to rotate and screw into the sliding block 10, so that the sliding block 10 drives the components such as the camera 11, signal transceiver 12, gas detection instrument 13, and buzzer warning light 14 to move up and down along the slideway, realizing the detection of different positions on the upper and lower tanks of the battery stack 1, positive electrolyte storage tank 2, and negative electrolyte storage tank 3. The buzzer warning light also provides a timely warning, allowing staff to promptly detect all-vanadium liquid electrolyte leaks.

[0090] Figure 3 A rear perspective view of the detection device and energy storage power station provided by the embodiment of the utility model, as shown Figure 3 As shown, the detection device further includes: a second forward and reverse motor 21 and a part B.

[0091] Among them, such as Figure 4 As shown, Figure 4 The embodiment of the present invention provides Figure 2 The partially enlarged structural diagram of point B in the middle includes: a driven gear 18 , a driving gear 22 , a second forward and reverse motor 21 and a pump body mounting base 19 .

[0092] The detection device further includes a first driving assembly, which includes a first driven member and a first active member. The first driven member is fixedly connected to the first structural member, and the first active member is transmission-connected to the first driven member.

[0093] Optionally, a driven gear 18 is fixedly provided at the lower end of the connecting bearing 4 located below.

[0094] Specifically, a circular cavity is defined in the driven gear 18 , and the inner wall of the circular cavity is connected to the outer walls of the lower ends of the battery stack 1 , the positive electrode electrolyte storage tank 2 , and the negative electrode electrolyte storage tank 3 .

[0095] Optionally, a pump body mounting seat 19 is provided at the lower end of the battery stack 1, and a second forward and reverse motor 21 is embedded in the pump body mounting seat 19. A driving gear 22 is fixedly installed on the upper end of the output shaft of the second forward and reverse motor 21, and the driving gear 22 is engaged with the driven gear 18.

[0096] Specifically, the second forward and reverse motor 21 is externally connected to a drive controller, so that when the second forward and reverse motor 21 rotates, the connecting bearing 4 can only rotate half a circle and then start to rotate back half a circle to prevent the circuit from being damaged by excessive twisting.

[0097] More specifically, the driving gear 22 is meshed with the driven gear 18 , so that the driving gear and the driven gear form a linkage.

[0098] In an embodiment of the present utility model, the rotation of the second forward and reverse motor drives the driving gear to rotate and engage with the driven gear, thereby causing the connecting bearing, horizontal plate, and vertical plate to rotate so that components such as the camera collection instrument, signal transceiver, gas detection instrument, and buzzer warning light can perform a comprehensive inspection of the outer wall of the tank.

[0099] The present utility model also provides a preferred embodiment, which provides specific steps for detecting leakage of a detection device and an energy storage power station.

[0100] First, the monitoring system is connected to the signal transceiver 12 using a line.

[0101] Secondly, the first forward and reverse motor 9 is controlled to rotate forward and reversely through an external drive controller. The rotation of the first forward and reverse motor 9 drives the threaded rod 8 to rotate, and the threaded rod 8 rotates and engages with the sliding block 10, so that the sliding block 10 drives the video acquisition instrument 11, the signal transceiver 12, the gas detection instrument 13, the buzzer warning light 14 and other components to move up and down along the slide 7, thereby realizing the detection of different upper and lower positions of the battery stack 1, the positive electrolyte storage tank 2 and the negative electrolyte storage tank 3.

[0102] Again, the second forward and reverse motor 21 rotates to drive the driving gear 22 to rotate, and the driving gear 22 rotates to engage with the driven gear 18, thereby rotating the connecting bearing 4, the horizontal plate 5, and the vertical plate 6, so that the camera collection instrument 11, the signal transceiver 12, the gas detection instrument 13, the buzzer warning light 14 and other components can perform a comprehensive inspection of the outer wall of the tank.

[0103] The second forward and reverse motor 21 rotates forward half a circle and reverse half a circle, performing reciprocating motion.

[0104] Finally, the video acquisition instrument 11 collects image information of the outer walls of the battery stack 1, the positive electrode electrolyte storage tank 2 and the negative electrode electrolyte storage tank 3, and then transmits it to the monitoring system for comparison through the signal transceiver 12. A judgment is made based on the comparison result. If there is a leakage, the signal transceiver 12 transmits the feedback information to the buzzer warning light 14 through the connecting line 15, causing it to flash and sound, to remind the staff. The gas detection instrument 13 is mainly used to detect leaks at positions where the video acquisition instrument 11 cannot capture images. When a leak occurs at such a position, the gas detection instrument 13 detects the air mixed with the all-vanadium liquid. If there is a leak, the gas detection instrument 13 transmits the electrical signal to the buzzer warning light 14 through the connecting line 15, causing it to flash and sound.

[0105] In the embodiment of the present utility model, the first forward and reverse motor is designed to rotate forward and reverse to drive the threaded rod to rotate and engage with the sliding block, so that the sliding block drives the camera acquisition instrument, signal transceiver, gas detection instrument, buzzer warning light and other components to move up and down along the slide slot, thereby realizing the detection of different upper and lower positions of the battery stack, the positive electrolyte storage tank and the negative electrolyte storage tank. The second forward and reverse motor rotates to drive the driving gear to rotate and engage with the driven gear, so that the connecting bearing, horizontal plate and vertical plate rotate, so that the camera acquisition instrument, signal transceiver, gas detection instrument, buzzer warning light and other components can perform a comprehensive detection of the outer wall of the tank, and timely issue an early warning through the buzzer warning light, so that the staff can promptly detect the leakage of the all-vanadium liquid electrolyte.
