Description
Technical Field
The invention belongs to the technical field of underwater observation operation equipment, and particularly relates to a seabed base monitoring system.
Background
The ocean plays a very important role in human survival and development. With the exploration and development of marine resources in China, the application of underwater observation instruments is increasing day by day. Due to the complex operation environment and harsh conditions, the traditional deck winch and submerged buoy system cannot meet the special environment use requirement.
At present, the monitoring means for the deepwater environment is still incomplete, and data acquired by various traditional technical means is limited, so that the acquisition of large-depth near-bottom in-situ observation data is particularly important. However, various observation instruments must be integrated on a carrying platform which can provide protection for the observation instruments and has a recycling function, so that the functions of the observation instruments can be realized. In order to explore and develop the ocean and protect the ocean rights and interests, a great amount of manpower and material resources are invested in various countries to research and develop the underwater in-situ observation platform technology.
The traditional underwater near-bottom in-situ observation platform mainly comprises a submerged buoy and a seabed base. The submerged buoy generally consists of a floating body, a cable for hanging instrument equipment, an acoustic releaser and a counterweight connected below the acoustic releaser, and has the advantages that: the throwing operation difficulty is small, the problem of poor bottom falling posture does not exist after the water is drained, the carrying capacity is strong, various devices can be hung, and the fishing and the recovery are easy; the disadvantages are that: the observation equipment is far away from the seabed. The seabed base usually consists of a bracket provided with instrument equipment, an acoustic releaser, a recovery cable and a counterweight, and has the advantages that: the carried equipment can be close to the seabed for observation; the disadvantages are that: the falling bottom posture of the sludge is difficult to ensure during throwing, and the sludge is difficult to recover once the sludge is overturned or falls into the sludge; when in recovery, the hoisting device is required to be used for pulling the cable rope through the recovery cable rope, so that the operation difficulty is higher.
In some existing solutions, a floating body is disposed in the onboard equipment, so that the onboard equipment receives a buoyancy force greater than its own gravity. However, in such a scheme, if the amount of sludge on the equipment is large, the buoyancy force applied to the embarkation equipment is not enough to lift the weight of the equipment and the sludge on the equipment, or sediment such as sludge enters between the equipment to be embarked and the seabed base, or the posture of the embarkation equipment when the embarkation equipment falls to the seabed is not ideal, the angle for separating the equipment from the seabed base deviates greatly from the vertical direction, and the buoyancy force is not enough to overcome corresponding frictional resistance, so that the embarkation equipment cannot be separated from the seabed base.

In particular, the plunger pump may be a straight axial plunger pump.
In an alternative embodiment, a locking device is further included for blocking the active power assisting device from disengaging the observation device 12 from the submersible device 11.

Since the lowermost loop of the chain 20 is only in contact with the lower surface of the straight portion, when the chain 20 at one end does not apply a force to the turn bar 21, the turn bar 21 is turned, and the turn bar 21 at the other end can be disengaged from the chain 20 at the other end. Since the U-shaped opening card 33 is opened, the rotating rod 21 can be detached from the supporting shaft 22 when the constraint of the tightened anchor chain 20 on both sides is completely lost.

By providing a gasket, the base plate 27 can be effectively sealed to prevent the ingress of seawater from the bottom of the observation device 12.
In an alternative embodiment, the observation device 12 is further provided with a rope compartment, a cable 36 is arranged in the rope compartment, one end of the cable 36 is connected with the observation device 12, and the other end of the cable 36 is connected with the sitting bottom device 11.
By providing the rope compartment in the observation device 12, the bottom device 11 can be fished by pulling up the bottom device 11 through the rope 36 after the observation device 12 is first retrieved.
In addition, a floating body 13 is provided in the observation device 12, and the floating body 13 in this embodiment may provide a buoyancy of 80 kgf. The observation device 12 is also provided with a doppler flow meter 14, a beacon 16, an inclinometer 17, and a salt Temperature and Depth measurement system 18(CTD, Conductivity, Temperature, Depth).
The operation principle of the embodiment is as follows:
when the seabed-based monitoring system of the present embodiment is assembled, the U-shaped opening clamp 33 of the rotating rod 21 is sleeved on the supporting shaft 22 from below, the lowermost rings of the two anchor chains 20 are respectively hung in the grooves at the two ends of the rotating rod 21, and the uppermost rings of the two anchor chains 20 are respectively hung on the hook parts of the acoustic releaser 15. The guide rod 31 of the observation device 12 is inserted into the disc spring 30, and by rotating the adjusting nut 28, the relative position of the guide rod 31 with respect to the bottom-seating device 11 can be adjusted, thereby adjusting the pitch of the observation device 12 to ensure that the rotation rod 21 can be kept horizontal and the anchor chain 20 can be tensioned. The belleville springs 30 are initially compressed by the weight of the viewing device 12 and the adjustment nut 28 may then be further rotated to preload the belleville springs 30 and store the elastic potential energy. Since the anchor chain 20 hooks the two ends of the rotating rod 21, the support shaft 22 transmits a downward force to the rotating rod 21 through the U-shaped opening clamp 33, so that the observation device 12 is ensured not to be ejected by the disc spring 30.
When it is desired to release observation device 12 from submersible device 11, the hook portion of one of acoustic release 15 is disengaged from the uppermost loop of anchor chain 20, e.g., the hook portion of acoustic release 15 on the right in the figure. At this time, the left chain 20 of the rotation rod 21 is still in a tensioned state and cannot immediately reduce the acting force to zero, so the left chain 20 gives a moment of clockwise rotation to the rotation rod 21, and the right chain 20 has a weight and also gives a moment of clockwise rotation to the rotation rod 21. The left end of the turning bar 21 is lifted up, the distance between the left end of the turning bar 21 and the hook part of the left acoustic releaser 15 is shortened, the left anchor chain 20 is loosened, and the lower end of the left anchor chain 20 is released from the groove at the left end of the turning bar 21. The left anchor chain 20 is disengaged from the swivel lever 21, the locking device is unlocked and the elastic potential energy of the belleville springs 30 may be released.
In this embodiment, the belleville springs 30 store a force of 400kgf, which together with the 80kgf provided by the float 13, may provide 480kgf, significantly greater than the 80kgf provided by the float 13 alone. The observation device 12 can be quickly detached from the submersible device 11 by the above-mentioned total force of 480 kgf. Even if the elastic energy storage device is unexpected, the bottom sitting device 11 can be pushed downwards by the push rod of the thruster assembly 19, and the reaction force of the bottom sitting device 11 to the thruster assembly 19 is transmitted by the thruster assembly 19 to drive the observation device 12 to be separated from the bottom sitting device 11.
When the observation device 12 is floated and recovered, since the observation device 12 is also connected to the bottom-seating device 11 through the cable 36, the bottom-seating device 11 can be carried away from the sea bottom by the cable 36, thereby recovering the bottom-seating device 11.
