[Technical field]

[0001] The invention relates to the technical field of lighting and beacon devices, and in particular to a self-triggering underwater lighting and beacon device. [Background technology]

[0002] Underwater lighting and beacon devices are necessary auxiliary tools for underwater construction such as seabed scientific surveys, engineering operations, and archaeological exploration. The search and positioning of underwater targets and work platforms mainly rely on lighting and acoustic beacons installed on large equipment such as underwater robots and drilling rigs. In the deep sea with a depth of more than 1,000 meters, the underwater acoustic positioning error is too large, which may affect the positioning needs of small-scale operations. Therefore, it is difficult to ensure that underwater operating equipment can quickly and accurately return to known operating points. At the same time, a device that is less affected by environmental interference such as seawater temperature and salinity is needed, and a device that can provide an important reference for the calibration of traditional underwater acoustic positioning systems is needed. [Summary of the invention]

[0012] The magnet is arranged outside the outer shell, and the circuit board includes a Hall switch, and the Hall switch detects magnetic force as the magnet moves, and becomes an on state or an off state;

[0013] The device body and the magnet are detachably connected.

[0014] Furthermore, the device body and the magnet are connected by a rope, and the rope is made of a decomposable material.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In order to enable those skilled in the art to better understand the present solution, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments in the present invention, other embodiments obtained by ordinary technicians in the field without creative work should all fall within the scope of protection of the present invention.

[0029] use Figure 1-Figure 3 The first state of the first embodiment of the present invention is described below:

[0030] The first state of the first embodiment of the present invention means that the magnet 5 is not separated from the device body 1, that is, the rope 4 connecting the device body 1 and the magnet 5 is in an unstretched state.

[0031] The first embodiment of the present invention comprises a device body 1, a pressure-resistant glass 2, a plug 3, and a magnet 5. The device body 1 comprises an outer shell 110, a pressure-resistant shell 130, a light-emitting lamp board 150, a battery 170, and a circuit board 190;

[0032] Depend on Figure 1 As shown, a countersunk hole is provided at the upper end of the outer shell 110; the pressure-resistant glass 2 is embedded in the countersunk hole at the top of the outer shell 110, and the pressure-resistant glass 2 can protect the light-emitting lamp board 150, the circuit board 190, and the battery 170 inside the device body 1 from being damaged by water pressure. The joint of the pressure-resistant glass 2 and the outer shell 110 can be pasted with a waterproof adhesive or treated with waterproof glue to prevent water from penetrating into the interior through the connection gap between the pressure-resistant glass 2 and the outer shell 110.

[0033] Depend on Figure 2As shown, in the first state, the rope 4 connecting the device body 1 and the magnet 5 is in an unstretched state, the rope 4 is received in the space in the countersunk hole at the bottom of the outer shell 110, and the magnet 5 is tightly attached to the lower end of the device body 1.

[0034] Figure 3 4 is a partial cross-sectional view of the first state of the first embodiment of the present invention.

[0035] The outer shell 110 is made of a floating material; the outer shell 110 can be made of, for example, a medium-density polyethylene float. Due to the use of a floating material, the device body 1 is in a positive buoyancy state in the water without a magnet. The outer shell 110 has a circular upper bottom surface and a circular lower bottom surface. The upper bottom surface and the lower bottom surface are circles with the same radius. Countersunk holes are respectively provided on the upper bottom surface and the lower bottom surface. A pressure-resistant glass 2 is embedded and fixedly installed in the countersunk hole of the upper bottom surface, and a plug 3 is detachably installed in the countersunk hole of the lower bottom surface. In the present embodiment, the outer shell 110 is a hollow cylinder with a certain thickness. In addition, the shape of the outer shell 110 can also be a cuboid or a cube.

[0036] The plug 3 is an integral component consisting of two stacked cylinders with a solid circular upper bottom surface and a solid circular lower bottom surface, and the radius of the upper circle is smaller than the radius of the lower circle. A rope 4 is connected to the lower end of the plug 3. The cylindrical part of the lower bottom surface of the plug 3 can be detachably installed at the countersunk hole at the bottom of the outer shell 110, forming a sealed environment with the outer shell 110. The cylindrical part of the upper bottom surface of the plug 3 is inserted into the channel at the bottom of the pressure-resistant shell 130. The channel at the bottom of the pressure-resistant shell 130 is cylindrical, and the radius of the channel is consistent with the radius of the upper bottom surface of the cylinder. The joint between the plug 3 and the pressure-resistant shell 130 can be affixed with a waterproof adhesive sticker or treated with waterproof adhesive to prevent water from penetrating into the interior through the gap between the plug 3 and the pressure-resistant shell 130. Similarly, the joint between the plug 3 and the outer shell 110 can be affixed with a waterproof adhesive sticker or treated with waterproof adhesive to prevent water from penetrating into the interior through the gap between the plug 3 and the outer shell 110.

[0037] The inner wall of the pressure-resistant housing 130, the plug 3 and the pressure-resistant glass 2 together form a sealed cavity;

[0038] The pressure-resistant shell 130 can be connected to the inner wall of the outer shell 110 by means of adhesive bonding or mortise and tenon fixing. The pressure-resistant shell 130 is made of non-magnetic material, preferably aluminum alloy or titanium alloy. Aluminum alloy and titanium alloy have the characteristics of low density, high stability and good pressure resistance, which can reduce the mass of the device body 1. By using non-magnetic materials, the pressure-resistant shell 130 will not generate attraction to the magnet 5, thereby not changing the distance between the magnet 5 and the bottom of the outer shell 110. The pressure-resistant shell 130 contains the entire battery 170 and the circuit board 190 as a whole, which plays a protective role.

[0039] The light-emitting lamp board 150 is arranged at the bottom of the pressure-resistant glass 2, so that the light emitted by the light-emitting lamp board 150 is emitted from the pressure-resistant glass 2. The light-emitting lamp board 150 is composed of a plurality of LED arrays. The LEDs can adopt different packaging structures such as SMT, COB, and direct plug-in. Preferably, the LED arrays composed of COB or SMT packaging structures are adopted. The light-emitting lamp board 150 is electrically connected to the circuit board 190, and the circuit board 190 dims the light-emitting lamp board 150. The dimming includes adjusting the switch, brightness, and flashing time of the LED lamp.

[0040] The circuit board 190 is arranged in the pressure-resistant shell 130. The circuit board 190 is arranged at the bottom of the sealed cavity. The circuit board 190 is electrically connected to a Hall switch. The Hall switch is an active magnetoelectric conversion device. It is made based on the principle of the Hall effect and is made using integrated packaging and assembly processes. It can easily convert magnetic input signals (magnetic induction signals) into electrical signals in practical applications. The input end of the Hall switch is characterized by the magnetic induction intensity B. When the B value reaches a certain level, the trigger inside the Hall switch flips, and the output level state of the Hall switch also flips accordingly. When the magnet 5 approaches the circuit board 190, the magnetic field is enhanced, the Hall switch outputs a low level or off signal, and the light-emitting lamp board 150 is in a non-luminous state.

[0041] The second state of the first embodiment of the present invention means that, under the action of gravity, the rope 4 connecting the magnet 5 and the device body 1 is in a stretched state, and the magnet 5 and the device body 1 are not in a close contact state.

[0042] like Figure 4-Figure 6 As shown, under the action of gravity, the rope stored in the space in the countersunk hole at the bottom of the outer shell 110 is released, and the rope 4 connected between the device body 1 and the magnet 5 is in a stretched state.

[0043] The device body 1 and the magnet 5 are connected by a rope 4, and the rope 4 is made of a decomposable material. After a certain period of time, the rope 4 can be decomposed, and the device body 1 can float to the water surface, and the device body 1 can be recycled and reused without causing pollution to the bottom of the water.

[0044] The magnet 5 is located at the lower end of the device body 1 and has a certain distance from the lower bottom surface.

[0045] The magnetic pole of the magnet 5 leaves the circuit board at the bottom of the device body 1, the magnetic field weakens, the Hall switch outputs a high level or open signal, the circuit becomes connected, and the light board 150 is in a light-emitting state.

[0046] use Figure 7-Figure 8 The second embodiment of the present invention is described as follows:

[0047] like Figure 7-Figure 8As shown, the plug 3 is detachably connected to the pressure-resistant shell 130, the circuit board 190 is provided with a data interface, and the device body 1 also includes a setting plug 6, which is installed at the bottom of the device body 1, and the setting plug 6 is pluggable and connected to the data interface of the circuit board 190. When the light-emitting frequency needs to be set, the plug 3 inserted into the bottom channel of the pressure-resistant shell 130 needs to be removed, one end of the setting plug 6 is connected to the data interface of the circuit board 190 in the device body 1, and the other end of the setting plug 6 is connected to the USB interface of the computer through a conversion data socket or a data conversion line. By adjusting the LED switching frequency on the computer, the characteristic frequency of the light of the self-triggering underwater lighting and beacon device can be adjusted. After the setting is completed, it is necessary to unplug one end of the setting plug 6 from the data interface of the circuit board 190, unplug the other end of the setting plug 6 from the data socket or the data conversion line, and then plug the plug 3 back into the channel of the pressure-resistant shell 130. The LED has a certain regular switch, that is, the LED light is flashing, and the flashing frequency represents a kind of information, which can be identified by the camera.

[0048] Through the above structure, a self-triggering underwater lighting and beacon device is provided. The self-triggering device does not work when it is not put into the water, and starts to work when it is put into the water. It is easy and simple to operate. In unknown areas under the water, lighting is provided to help observe organisms or terrain. Lighting is provided in narrow spaces that cannot be explored or entered by diving equipment. After the underwater terrain or resources are explored, it will flash at a flashing frequency, and the flashing frequency can have the function of Morse code. The information carried by the flashing frequency can be identified by the camera, which plays the role of marking the underwater terrain or resources. The rope of the self-triggering underwater lighting and beacon device is made of decomposable materials. After a certain period of time, the rope can be decomposed, and the main body can float to the surface of the water for recycling, without causing pollution to the bottom of the water. In addition, when carrying out grid-based fine operations in a deep-water operation area with a smaller range (less than the underwater acoustic positioning error), the device can provide important positioning functions for addressing work platforms with underwater monitoring functions.

[0049] When in use, the mass of the magnet 5 can be adjusted as needed to determine whether the self-triggered underwater lighting and beacon device is suspended or sunk in the water. When the overall buoyancy of the device body 1 and the magnet 5 is equal to the gravity, the self-triggered underwater lighting and beacon device is suspended in the water after being put into use. When the overall buoyancy of the device body 1 and the magnet 5 is less than the gravity, it sinks to the bottom of the water after being put into use. The state of the self-triggered underwater lighting and beacon device at the bottom of the sea is that the magnet 5 touches the bottom of the water, and the device body 1 connected thereto floats above it, and the whole formed by the magnet 5 and the device body 1 maintains a stable state at the bottom of the water, and will not drift with the water flow, thereby ensuring the stability of the triggered underwater lighting and beacon device at the bottom of the water.

[0050] When not in use, the magnet 5 and the device body 1 are placed close to each other. Since the rope 4 connecting the device body 1 and the magnet 5 is not affected by gravity, the rope 4 is in an unstretched state. The magnet 5 and the device body 1 are placed together, and the magnet 5 is close to the circuit board 190. Since the Hall switch is affected by magnetic force, the light panel 150 is in a closed state.

[0051] When the self-triggering underwater lighting and beacon device needs to be placed into a small underwater space or an unknown underwater area, after being placed, because the density of the device body 1 and the magnet 5 is different, the buoyancy of the device body 1 is greater than its own gravity, and the buoyancy of the magnet 5 is less than the gravity of the magnet, the magnet 5 and the device body 1 move downward at different accelerations, the rope 4 is stretched, the magnet 5 leaves the device body 1, the Hall switch is not affected by the magnetic force, and the light-emitting light board 150 is in the on state. After the magnet 5 touches the bottom, the device body 1 is suspended in the water, and the light-emitting light board 150 provides lighting for a long time to help see the organisms or terrain clearly. The advantage of the self-triggering design is that when the self-triggering underwater lighting and beacon device is stored in a submersible or in a hull, it is placed horizontally and the device does not work. When it is put into the water, the magnet 5 and the device body 1 will automatically separate, the Hall switch will be in the on state, and the self-triggering underwater lighting and beacon device will start to work. The operation is novel and the setting is simple.

[0052] Too large an underwater acoustic positioning error may affect the positioning requirements of small-scale operations, making it difficult to ensure that underwater operating equipment can quickly and accurately return to known operating points. In addition, when conducting grid-based fine operations in a small-scale (smaller than the underwater acoustic positioning error) deep-water operating area, the device can provide an important positioning function for addressing operating platforms with underwater monitoring functions. It can provide an important reference for the calibration of traditional underwater acoustic positioning systems.

[0053] Sometimes when useful targets are detected underwater or when it is necessary to mark an operation point or operation platform, it is necessary to place a signal device underwater to indicate the intention. When the self-triggered underwater lighting and beacon device reaches the seabed or explores the underwater terrain, it can flash at a preset flashing frequency or different light and dark combinations. The flashing frequency or light and dark combination can have the function of Morse code, carrying the information written and marked at the preset time, which can uniquely identify the deployed self-triggered underwater lighting and beacon device. The information carried by the flashing frequency can be identified through the camera of the underwater operation platform or the camera of the operation equipment, which assists the traditional underwater acoustic positioning system to help the operation equipment quickly return to the known operation point.

[0054] The rope 4 of the self-triggering underwater lighting and beacon device is made of decomposable materials. After a certain period of time, the rope 4 can be decomposed, and the device body 1 can float to the water surface without causing pollution to the bottom of the water. After the rope 4 is decomposed, the battery 170 in the device body 1 is basically used up, and the self-triggering underwater lighting and beacon device is equivalent to failure. It needs to be re-deployed. As the device body 1 floats to the water surface, the device body 1 can be recycled and reused.

[0055] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
