AI Technical Summary
Existing underwater detection devices are prone to fluctuation when observing underwater, cannot fix the direction, and have limited expansion and contraction distance, making it difficult to achieve underwater detection and observation at a depth of multiple meters or even dozens of meters.
A strong tension spring is used as the soft cable housing. The cable passes through the tension spring and connects to the probe. The probe is telescopic and remotely controlled rotation are achieved by rotating the wire disk, and the elasticity of the tension spring is used to maintain the stability of the probe.
It realizes stable observation and remote monitoring underwater at a depth of more than ten meters or even dozens of meters. The probe is not easy to be damaged and can be retracted and retracted freely. It is suitable for a variety of underwater detection occasions.

Abstract
Description
Technical Field
[0001] The present invention relates to a monitoring and detecting device, which can observe and detect underwater, especially can submerge a display probe into the water on an unmanned boat, and can observe and detect underwater conditions on board or on shore. The device is composed of a wire reel, a cable, a controller, a motor, a tension spring, a probe, etc., and is called an unmanned boat underwater monitoring and detecting device. Background Art
[0002] The underwater detection device of unmanned boats is mainly used to detect mines and semi-submersible unmanned boats arranged on the water surface, especially mines. Although mines float on the water surface, they are semi-submersible for concealment, that is, most of them are not below the water surface, and it is not easy to observe from the water surface. It is easy to observe by putting the display probe into the water. If the display probe is directly placed in the water and connected only by cables, the probe will sway unsteadily, without a fixed direction, and remote monitoring is impossible; there are telescopic probes on the market, but they can only extend one or two meters, so underwater detection has always been a headache for people. People expect to observe the underwater situation on board or on shore, especially underwater detection, observation, search, and sampling at a depth of more than ten meters or even tens of meters.
[0003] The present invention uses a strong tension spring as the soft cable shell. The advantage of the tension spring is that it can be bent and can be straightened without external force. The thicker the wire diameter, the stronger the elasticity. The greater the elastic force, the less easy it is to bend. The cable passes through the tension spring and is connected to the probe, so that it can be observed under water more than ten meters deep. When it is retracted, the soft cable with the tension spring shell is wound on a relatively large rotating reel. Why is it relatively large? Because most unmanned boats are seven or eight meters long and about two meters wide, and the diameter of the rotating reel is about two meters. When the reel rotates, the display probe can be extended and retracted. The tension spring is appropriately bent in the large reel. When the display probe is extended, the tension spring is straightened due to the elastic force of the tension spring. At this time, the remote control can freely control the remote control probe to rotate and observe.
[0004] The underwater monitoring detector introduced in the present invention can dive to a depth of 10 to 20 meters underwater. If it is used on a larger boat, the wire diameter and the disc can be increased to dive to a depth of 40 to 50 meters underwater.
[0005] The present invention will be a good helper for warships, scientific research vessels, rescue boats, and hydrological detection. Summary of the invention
[0006] The invention designs an underwater detector with a tension spring housing according to the needs of underwater detection of an unmanned boat.
[0007] The present invention is implemented as follows: the cable passes through a tension spring and is wound in a wire drum, which is installed in a cabin at the rear of an unmanned boat. A motor controls a rotating frame in the disk to retract and release the cable. After the cable is retracted, the tension spring is slightly bent by the restriction of the wire drum. A roller bearing is provided at the outlet of the wire drum to make the cable retracted and released smoothly. Sealant is provided on the bottom of the boat to prevent water from entering the unmanned boat. One end of the cable is connected to a monitoring probe and the other end is connected to a monitoring display. The motor propeller of the unmanned boat propeller and the wire drum motor are driven by batteries in the cabin.
[0008] The technical effects of the present invention are: 1. The display probe will not swing in the water and can be freely controlled by the remote control; 2. Even if it hits any object underwater, it is not easily damaged because the tension spring is elastic; 3. It can be freely retracted and extended; 4. It is suitable for a variety of occasions requiring underwater detection.
[0009] The underwater monitoring and detecting device introduced in the present invention is suitable for any boats and the shape of the tension spring is not limited. BRIEF DESCRIPTION OF THE DRAWINGS
