Description

Technical Field

[0001] The invention belongs to the technical field of sonar buoys, and in particular relates to a device for releasing an underwater cable of a buoy upwards. Background Art

[0002] Sonar buoy equipment is widely used in marine environment measurement and target identification. When the buoy detection sensor works at different underwater depths, different detection results will be obtained. Since the detected target and underwater environment are complex and changeable, the buoy working depth state requires real-time remote control and rapid reaching of the set depth. Therefore, it is necessary to set up an underwater cable cabin, a cable release device and a remote control system device to control the release length of the buoy sensor cable and realize the selection and control of the working depth.

[0003] There are two ways to select the depth of the buoy: releasing the cable downwards or releasing the cable upwards. In the former, the cable release device and the cable cabin are fixedly installed below the surface cabin, and the signal cable is connected to the release device and controlled by the surface cabin. In this method, the surface cabin, the release device and the cable cabin are rigidly connected, and the whole is significantly affected by the impact and vibration of the waves, and the cable is subject to the friction resistance of the water body, which slows down the release speed. The latter mostly uses a gear set and a dial mechanism, or tying knots and plugging and pulling pins to control the upward release of the cable, but the buoy using this method needs to be manually adjusted to select the depth gear before being deployed. The operation is complicated and secondary control cannot be performed after the buoy is deployed, which greatly limits the detection range of the buoy. Summary of the invention

[0004] In view of this, in order to solve the problems and shortcomings of the prior art, the present invention provides a buoy underwater cable upward releasing device, which can remotely control the buoy to select the depth state and quickly release the cable, greatly expanding the detectable depth range of the buoy and ensuring that the buoy's floating stability and sensor detection performance are not disturbed.

[0005] The technical solution of the present invention is:

[0006] A buoy underwater cable upward releasing device, comprising:

[0007] The surface tank shell has a signal receiving and processing circuit board inside, and the circuit board is connected to the control signal line, and the control signal line is led out from the bottom of the surface tank shell;

[0008] A cable compartment shell is nested with the bottom of the surface compartment shell, and a cable reel is installed inside. A load-bearing rope is tied to the preset cable length position of the cable reel. The cable at one end of the cable reel passes through the upper through hole of the cable compartment shell, and the cable at the other end passes through the lower flange of the cable compartment shell;

[0009] The underwater cabin body component comprises an underwater cabin shell, a hatch, a depth control circuit board and a battery pack; the underwater cabin shell is coaxially fixedly connected with the cable cabin shell, and the hatch cover seals the end of the underwater cabin shell away from the cable cabin shell; wherein the battery pack provides power to the depth control circuit board through a power line, and the threading holes of the underwater cabin body component are coated with sealant for waterproofing;

[0010] The cable release mechanism is installed between the lower flange of the cable compartment shell and the underwater compartment shell; it is controlled by the depth control circuit board and selects the load-bearing rope required for fusing based on the fusing method.

[0011] Furthermore, the wire holes of the surface tank shell are coated with sealant for waterproofing.

[0012] Furthermore, the threading holes of the underwater cabin components are coated with sealant for waterproofing.

[0013] In this embodiment, the cable release mechanism includes a nylon rope, a control cable, a sleeve, a heating resistor wire and a tension spring; the heating resistor wire is spirally wound around the nylon rope, both ends of the heating resistor wire are connected to the control cable, the nylon rope passes through the sleeve and the heating resistor wire is located inside the sleeve, and sealing grease is added to the sleeve for waterproof sealing; the nylon rope is tied into a ring after passing around the cover plate, and one end of the tension spring is hung on the rope ring of the nylon rope.

[0014] Furthermore, a mounting frame is provided at one end of the underwater cabin shell away from the cabin cover; and the cable release mechanism is installed on the mounting frame.

[0015] Furthermore, the flange is mounted on the end of the cable compartment shell away from the surface compartment shell and has a portion protruding out of the cable compartment shell; the portion of the flange inside the cable compartment shell is fixed based on bolts inserted from the outside of the cable compartment shell; the portion of the flange protruding from the cable compartment shell is mounted in the underwater compartment shell, and the portion of the flange inside the underwater compartment shell is fixed based on bolts inserted from the outside of the underwater compartment shell.

[0016] Furthermore, one end of the cable cabin shell and one end of the underwater cabin shell have the same inner and outer diameters.

[0017] Furthermore, the cable reel is connected to the control signal line extending from the bottom of the surface cabin component, and the load-bearing rope extending from the wire hole of the bottom flange of the cable cabin component is tied to the nylon rope in the cable release mechanism;

[0018] The depth control circuit board in the underwater cabin component leads the cable upwards and connects with one end of the cable reel, and the control cable of the cable release mechanism is connected with the depth control circuit board;

[0019] In this embodiment, the buoy remote control cable release device fixes the cover plate and one end of the tension spring on the underwater cabin shell based on screws, wherein the tension spring is in a stretched stress state after being fixed, and the nylon rope is tensioned under the tensile force.

[0020] Compared with the prior art, the technical solution proposed in the present invention has the following beneficial effects:

[0021] In the overall system after the buoy is deployed, the surface cabin components and the cable cabin components are independent of each other and are connected by flexible cables. The cable cabin becomes a damping part to reduce vibration, thereby improving the detection performance of the buoy equipment.
