Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0019] See also Figure 1-Figure 7 An underwater multi-channel data acquisition instrument comprises an acquisition instrument body 100, a monitoring head 200 and a transparent protective cover 300 are respectively installed at the bottom of the acquisition instrument body 100, a sensor input interface 400 is installed at the top of the acquisition instrument body 100, and an optical cable interface 500 is installed at the side of the acquisition instrument body 100; The interior of the collector body 100 is provided with a protective assembly 600, which includes a hydraulic chamber 601 and a storage chamber 602.

The inner side of the transparent protective cover 300 is equipped with a liquid-conducting cotton core 603, which partially passes through the collector body 100 and is located inside the storage chamber 602. When the sealing ring between the transparent protective cover 300 and the collector body 100 ages, causing the gap between the transparent protective cover 300 and the collector body 100 to begin to seep water, the infiltrated liquid is immediately conducted to the storage chamber 602 by the liquid-conducting cotton core 603, and reacts with the calcium oxide powder stored in the storage chamber 602, releasing a large amount of heat. One end of the hydraulic bin 601 is slidably connected to a transmission rod 604, and the other end of the hydraulic bin 601 is slidably connected to a clamping rod 1 605. A spring 1 606 is fixedly connected to the side of the transmission rod 604. The spring 1 606 is located at an inner position of the hydraulic bin 601 away from one end of the transmission rod 604, and is fixedly connected to the inner wall of the hydraulic bin 601. The sides of the storage bin 602 and the transmission rod 604 are both connected to a thermosensitive glass 607 by setting a replacement component 800. When a large amount of heat is released in the storage bin 602, the thermosensitive glass 607 is broken by the heat. At this time, the transmission rod 604 connected to the thermosensitive glass 607 by the replacement component 800 loses its restriction, and under the action of the spring 1 606 fixedly connected thereto, slides into the hydraulic bin 601 slidably connected thereto, so that the pressure in the hydraulic bin 601 increases, driving the clamping rod 1 605 slidably connected to the hydraulic bin 601 to move.

[0020] During use, when the sealing ring between the transparent protective cover 300 and the collector body 100 ages, causing the gap between the transparent protective cover 300 and the collector body 100 to begin to leak water, the infiltrated liquid is immediately conducted to the storage bin 602 by the liquid-conducting cotton core 603, and reacts with the calcium oxide powder stored in the storage bin 602, releasing a large amount of heat, thereby causing the thermosensitive glass 607 to break. At this time, the transmission rod 604 connected to the thermosensitive glass 607 by the replacement component 800 loses its restriction, and under the action of the spring 1 606 fixedly connected thereto, it slides into the hydraulic bin 601 slidably connected thereto, causing the pressure in the hydraulic bin 601 to increase, driving the clamping rod 1 605 slidably connected to the hydraulic bin 601 to move, and the clamping rod 1 605 It is then moved out of the slot 610 on the spare protective cover 609, so that the spare protective cover 609 loses its restriction and starts to rotate under the action of the torsion spring rod 608 fixedly connected to it; and when the slot 610 rotates to the second clamping rod 614, the second clamping rod 614 loses the restriction of the outer wall of the spare protective cover 609, and the transmission plate 613 fixedly connected to the second clamping rod 614 loses the restriction synchronously, and under the action of the second spring 612, the second clamping rod 614 is driven by the transmission plate 613 to move into the slot 610, and the restriction on the spare protective cover 609 is completed again; at this time, the spare protective cover 609 has been rotated from the inside of the collector body 100 to the bottom position of the monitoring head 200, and part of the spare protective cover 609 is inserted into the sealing seat 615. Example

When the second clamping rod 614 moves into the clamping slot 610, the sensing airbag 702 is squeezed by the inner wall of the clamping slot 610. The other end of the pressure chamber 701 is fixedly connected to a sealing airbag 703. When the sensing airbag 702 is squeezed by the inner wall of the card slot 610, the gas stored in the sensing airbag 702 is squeezed into the air pressure chamber 701 which is fixedly connected and communicated with the sensing airbag 702, and the original gas in the air pressure chamber 701 is immediately squeezed into the sealed airbag 703 which is fixedly connected and communicated with it. The sealed airbag 703 then expands to seal the gap between the card rod 2 614 and the card slot 610, thereby further improving the use effect of the protective component 600.

[0022] During use, based on the first embodiment, when the second clamping rod 614 moves into the clamping slot 610, the sensing airbag 702 is squeezed by the inner wall of the clamping slot 610, and cooperates with the air pressure chamber 701 fixedly connected and communicated with the sensing airbag 702, so that the gas stored in the sensing airbag 702 is squeezed into the air pressure chamber 701, and the original gas in the air pressure chamber 701 is immediately squeezed into the sealed airbag 703 fixedly connected and communicated with it, and the sealed airbag 703 immediately expands to seal the gap between the second clamping rod 614 and the clamping slot 610.
