Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to a warning device and warning method for water operations. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can water flow be controlled to meet the needs of people's life and production for water resources. Water-based operations are indispensable in water conservancy projects.

[0003] Waterborne operations include: setting up and dismantling above-water and underwater facilities; constructing wharves, docks, slipways, and locks; building various types of dikes or artificial islands; erecting bridges and cableways; constructing underwater tunnels; salvaging sunken ships and objects; laying, removing, and repairing above-water and underwater cables or pipelines; setting up fixed nets for fishing and aquaculture; setting up mooring buoys, floating platforms, bamboo and wooden raft mooring bollards, and similar facilities; conducting marine and meteorological observations, hydrological surveys, geological surveys, and scientific research activities that affect water traffic safety; removing surface debris; dredging, blasting, pile driving, pile extraction, landfilling, sand dredging, gold panning, quarrying, and dumping mud and gravel; rescuing distressed vessels or urgently removing surface and underwater pollutants; and other construction operations that affect navigational safety or the navigation environment. During waterborne operations, to improve safety, waterborne warning equipment is used to warn vessels to stay away from the operation area.

[0004] However, existing maritime warning equipment has a limited warning range, meaning that by the time vessels see the warning information, they are often too late to leave, leading to accidents. Furthermore, when warning maritime work areas at night, existing equipment relies solely on warning signs within the work area, resulting in limited coverage and poor early warning capabilities, significantly increasing safety hazards.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0051] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar words used in one or more embodiments of this specification do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0052] To facilitate understanding of the waterborne operation warning equipment and methods provided in this application embodiment, their application scenarios are first explained. Waterborne operations include: setting up and dismantling above-water and underwater facilities; constructing wharves, docks, slipways, and dams; building various embankments or artificial islands; erecting bridges and cableways; constructing underwater tunnels; salvaging sunken ships and objects; laying, removing, and repairing above-water and underwater cables or pipelines; setting up fixed nets for fishing and aquaculture; setting up mooring buoys, floating platforms, bamboo and wooden raft mooring bollards, and similar facilities; conducting marine and meteorological observations, hydrological measurements, geological surveys, scientific research, and other activities that affect waterborne traffic safety; removing surface garbage; sweeping, dredging, blasting, pile driving, pile extraction, landfilling, sand dredging, gold panning, quarrying, and dumping mud and gravel; rescuing distressed vessels or urgently removing surface and underwater pollutants; and other construction operations that affect the safety of navigation waterways or the navigation environment. During water operations, to improve safety, waterborne warning equipment is used to alert vessels to stay away from the work area. However, existing warning equipment has a limited range, meaning that by the time vessels see the warning information, they are often too late to leave, leading to accidents. Furthermore, at night, existing warning equipment relies solely on warning signs in the work area, resulting in limited coverage and poor early warning performance, significantly increasing safety hazards. Therefore, the waterborne operation warning equipment and method proposed in this application employs a circumferential rotation warning system with increased warning height and uses laser lines to alter the water's color, providing comprehensive warning of the work area and improving the safety of waterborne operations.

[0053] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first state of the warning equipment for water operations. Figure 2 This is a schematic diagram of the second state of the waterborne operation warning device. The first state of the waterborne operation warning device in this application involves raising the device to provide comprehensive coverage and early warning of the waterborne work area. The second state involves the waterborne robot body 100 moving to different areas to provide early warning or targeting smaller waterborne work areas. The waterborne work area warned by this device is relatively wide, i.e., a safe distance from the construction site. Depending on the size of the waterborne work area, multiple waterborne robot bodies 100 or waterborne robot bodies 100 can be selected for patrol and early warning.

[0054] The waterborne operation warning device includes a waterborne robot body 100. As a waterborne mobile device in this embodiment, the waterborne robot body 100 is remotely controlled and equipped with multiple cameras 110. It captures images, and its travel area is precisely controllable. Specifically, the waterborne robot body 100 performs warning operations after traveling on the water surface to the waterborne work area. Controlling its navigation trajectory uses common techniques in the prior art, which will not be elaborated upon here.

[0055] The main body 100 of the water robot is provided with a roll bag storage compartment 140; the roll bag storage compartment 140 is rotatably connected to the main body 100 of the water robot; the roll bag storage compartment 140 is used to store the roll bag 200, so that the main body 100 of the water robot does not generate wind resistance and equipment damage when moving to the next water work area.

[0056] The storage roll bag 200 has an inner water column cavity 201 and an outer air inflation cavity 202. The storage roll bag 200 is connected to a water pump assembly 120 that communicates with the water column cavity 201 and an air pump assembly 130 that communicates with the air inflation cavity 202. When the water pump assembly 120 and the air pump assembly 130 stop running, the storage roll bag 200 is located in a spiral state inside the roll bag storage compartment 140. The storage roll bag 200 is a flexible bag body and is connected to the inside of the roll bag storage compartment 140 through a torsion spring shaft. The flexible bag body achieves automatic storage under the action of the torsion spring shaft, and the air pump assembly 130 ensures that the inflation pressure is sufficient before the storage roll bag 200 can extend vertically.

[0057] The water pump assembly 120 injects high-pressure water into the water column chamber 201, ensuring the storage roll bag 200 remains vertical and stable. A fixing post 210 is positioned on top of the storage roll bag 200, and an audible and visual warning light 410 is mounted on the fixing post 210. Specifically, a fixing plate 400 is mounted on the top of the fixing post 210, and the audible and visual warning light 410 is fixedly mounted on the fixing plate 400. The installation performance is stable. The audible and visual warning light 410 flashes red when positioned high, and when the camera 110 captures or the laser beam detects a vessel approaching the water operation area, it broadcasts a loudspeaker to drive the vessel away. A fixed warning sign 310 is positioned opposite the fixing post 210, enhancing the early warning performance at higher locations.

[0058] Combination Figure 3As shown, it also includes a first warning component; the first warning component includes multiple warning signs 300 distributed relatively; when the water pump component 120 and the air pump component 130 are working, the storage roll bag 200 extends vertically upward along the top of the roll bag storage compartment 140, and the multiple warning signs 300 are magnetically connected to the storage roll bag 200 at intervals along the height direction of the storage roll bag 200, and each warning sign 300 has multiple first laser emitters 301 arranged in an array; the first laser emitter 301 emits a warning colored laser line with a long illumination distance to ensure early warning and multiple warnings at night.

[0059] During the process of raising the storage roll bag 200 and magnetically fixing the warning sign 300, the storage roll bag 200 is provided with a trapezoidal groove 203 that can be formed under high pressure. The fixing column 210 is provided with the same trapezoidal groove 203, and each of the multiple warning signs 300 is provided with a trapezoidal block 302 that cooperates with the trapezoidal groove 203. The flexible bag body is used for easy storage and provides stable support under the action of gas and water columns. Multiple electromagnetic groups 204 are arranged at intervals along the height direction inside the trapezoidal groove 203, and each trapezoidal block 302 is provided with an electromagnetic block that is magnetically attracted to the corresponding electromagnetic group 204. Electromagnetic adsorption is used to improve stability. The top of the roll bag storage compartment 140 is provided with a support compartment 150 for storing multiple warning signs 300; multiple warning signs 300 on the same side are stacked and stored sequentially along the height direction of the corresponding support compartment 150. This allows for convenient storage when high-altitude warnings are not required.

[0060] This should be understood as follows: a set of electromagnetic groups 204 located at the highest point inside the trapezoidal groove 203 magnetically attracts the warning sign 300 at the highest point in the carrying chamber 150; a set of electromagnetic groups 204 located in the middle of the trapezoidal groove 203 magnetically attracts the warning sign 300 at the highest point in the carrying chamber 150 at this time. As the warning sign 300 extends with the storage roll bag 200, it sequentially detaches from the carrying chamber 150. The top of the carrying chamber 150 and the side facing the storage roll bag 200 are open, thereby collecting position information through the control system and sequentially activating the electromagnetic groups 204 and the electromagnetic blocks to ensure stable magnetic attraction performance. The sequential magnetic attraction order can be determined by installing position sensors, which are existing technologies known to those skilled in the art and will not be elaborated upon here.

[0061] Please refer to the above. Figure 1 and Figure 4The system also includes a second warning component. This second warning component comprises a telescopic column 180 located at the bottom of the water robot body 100, a mounting plate 170 mounted on the telescopic column 180, and multiple second laser emitters 171 circumferentially arranged on the side wall of the mounting plate 170. The telescopic column is an electrically operated telescopic rod (180mm) that illuminates water layers of varying turbidity. For clear water layers, the illumination depth can be controlled to be greater, and the intensity of the illumination is increased by increasing the color intensity. A drive component is installed inside the water robot body 100, which drives the telescopic column 180 and the roll-up storage compartment 140 to rotate synchronously in the circumferential direction.

[0062] Specifically, the drive assembly includes: a drive column 500 rotatably connected inside the body 100 of the water robot, a main gear 520 mounted on the drive column 500, and a drive motor 510 for driving the drive column 500 to rotate circumferentially; wherein, the output shaft of the drive motor 510 is provided with a drive gear 530 that meshes with the main gear 520; the top of the drive column 500 is connected to the top of the body 100 of the water robot via a first bearing plate 160, and the bottom of the drive column 500 is connected to the bottom of the body 100 of the water robot via a second bearing plate 190; a water pump assembly 120 and an air pump assembly 130 are stacked on the first bearing plate 160 from bottom to top, and both the water pump assembly 120 and the air pump assembly 130 are equipped with mounting housings, which are connected to the first bearing plate 160 in a stacked manner through the mounting housings; the roll bag storage compartment 140 is fixedly connected to the mounting housing of the air pump assembly 130; a telescopic column 180 is mounted upside down on the second bearing plate 190. Synchronous drive is achieved, improving early warning performance during circumferential rotation. A water suction hood 121 is installed on the mounting plate 170, and the water suction hood 121 is connected to the water pump assembly 120 through a flexible tube 122. It has follow-up performance and continuously provides a high-pressure water jet.

[0063] As can be seen from the above structure, the warning range is expanded by means of linkage rotation, and the water color of the working area on the water is changed at night to provide high-performance early warning.

[0064] In this application, the storage roll bag 200 is raised by using gas and water flow to drive the first warning component to provide an early warning of height changes, and the second warning component extends into the water layer to change the color of the water layer in the water work area, thereby enhancing the early warning at night; at the same time, the rotation method is used to fully cover a large area of ​​the water work area, with good early warning performance and improved safety of water operations.

[0066] S1. The water robot moves to the water operation area.

[0067] S2. The air pump assembly injects gas into the inflation chamber, and the storage roll bag rises vertically along the storage compartment.

[0068] S3. During the inflation process of the storage roll bag, a trapezoidal groove is formed, and the electromagnetic group inside the trapezoidal groove sequentially attracts the corresponding electromagnetic blocks.

[0069] S4. Multiple warning signs are connected to the storage roll bag in a relatively distributed manner to increase the warning height.
