[0023] Embodiment 2

[0024] In order to facilitate the seismograph to be placed and taken out, in the embodiment, Figures 1-3As shown, the upper end of the protective shell 2 is symmetrically fixed with support plates 8, two support plates 8 are rotatably connected with a rotating roller 9, the outside of the rotating roller 9 is wound with a pull rope 10, the lower end of the pull rope 10 is fixedly connected with the rotating roller 9, and the upper end is fixedly connected with a floating object 11, the upper end of the release base 1 is fixedly installed with a plurality of L-shaped support plates 5 at equal intervals, the lower end of the L-shaped support plate 5 is fixedly installed with a counterweight 6, a plurality of through holes 7 are arranged in the counterweight 6 at equal intervals, the release base 1 is circular, the bottom of the counterweight 6 is horizontal to the bottom of the release base 1, the side wall of the counterweight 6 close to the side wall of the release base 1 is tapered, and the side wall of the counterweight 6 is not in contact with the side wall of the release base 1. When the seismograph is released, the staff first takes the floating object 11, and places the release base 1 on the sea surface. Under the action of the counterweight 6, the release base 1 can quickly drive the seismograph placed inside to move towards the seabed. At the same time, because the position of the floating object is fixed, the release base 1 will drive the rotating roller 9 to rotate while moving downward, and the pull rope 10 will be unwound and extended until the position of the pull rope 10 no longer stretches. At this time, the staff releases the floating object 11, and the floating object 11 floats on the sea surface, which is convenient for positioning and subsequent recovery of the seismograph.

[0025] It should be noted that in the embodiment, as shown, Figures 1-3 When the seismograph is released, the staff first takes the floating object 11, and places the release base 1 on the sea surface. Under the action of the counterweight 6, the release base 1 can quickly drive the seismograph placed inside to move towards the seabed. At the same time, because the position of the floating object is fixed, the release base 1 will drive the rotating roller 9 to rotate while moving downward, and the pull rope 10 will be unwound and extended until the position of the pull rope 10 no longer stretches. At this time, the staff releases the floating object 11, and the floating object 11 floats on the sea surface, which is convenient for positioning and subsequent recovery of the seismograph, and the release base 1 contacts the bottom surface of the seabed after the seismograph is placed on the seabed, so that the position of the device is placed stably. When the seabed has seawater flowing, the seawater below will enter the inside of the first flow guide hole 3 or the second flow guide hole 4, and will flow out through the inside of the second flow guide hole 4 or the first flow guide hole 3, so that a negative pressure is formed in the inside of the first flow guide hole 3 and the second flow guide hole 4, which is convenient for placing the release base 1 stably. As for the protective shell 2, the seawater will impact the flow guide block 13. Since the position of the flow guide block 13 is inclined, the seawater impacting the flow guide block 13 will make the rotating ring 12 rotate, thereby reducing the impact force of the seawater on the protective shell 2 and improving the stability of the seismograph when placed on the seabed.
