[0003] Ship models are the epitome of ships, which can integrate the concentrated ship culture with history, science and art. At present, schools usually use paper models, wooden models or electric remote control models as carriers to guide students to learn ship model making technology and explore the structure of the ships they make, so that students can improve their hands-on ability and teamwork ability while increasing their knowledge. However, most of the ship models currently made only have the function of demonstrating the overall structure of the ship. Even if some ship models can present dynamic demonstrations, they are only limited to driving on the water surface. The function is single, which is not conducive to students further combining the knowledge learned in science classes with real life. Therefore, there is an urgent need for a convenient unmanned ship that can expand students' horizons in ship model science classes and even in real life, and combine theory with practice.

Detailed implementation manners

[0025] As Figures 1-5 shown, they are respectively the schematic diagrams of different structures of the portable water - sample - collecting unmanned boat model of the present utility model and the structure after removing the main cabin (only leaving the main - cabin bottom plate) and the related components installed on the main cabin. It can be seen from the figure that the portable water - sample - collecting unmanned boat model of the present utility model includes: a main cabin 2 for accommodating a circuit board (not shown in the figure) therein; a pair of pontoons 10 arranged on the left and right sides of the main cabin and fixedly connected thereto; a pair of thrusters 7 respectively installed on the pair of pontoons; an anemometer 12 and an upper camera 1 arranged above the main cabin; a front camera 3 arranged on the front side and a rear camera 11 arranged on the rear side of the first pontoon in the pair of pontoons; a front lighting lamp 5 arranged on the front side and a rear lighting lamp 8 arranged on the rear side of the second pontoon in the pair of pontoons; a rear winch 9 arranged on the rear side of the main cabin; a pair of solar charging panels 6 respectively arranged above the pair of pontoons.

[0026] Specifically, the portable water - sample - collecting unmanned boat model of the present utility model forms the support structure of the whole unmanned boat through the main cabin and a pair of pontoons. Among them, the pontoons are made of PVC down - pipes with a diameter of about 110 mm and a length of about 910 mm (the maximum load is about 8 KG). The size of the pontoons can be determined by buoyancy experiments according to the estimated load counterweight.

[0027] The main cabin is an enclosed cabin with a cavity inside. The circuit boards and related electronic components required for the unmanned boat are placed inside it (not shown in the figure. During application, the circuit boards and required electronic components can be integrated in advance so that students can directly fix the integrated circuit board on the bottom plate of the main cabin during assembly). The bottom plate, top plate, and each side plate of the main cabin can be made of 4mm thick wooden boards. During production, a suitable mortise and tenon structure is set at the connection of each board so that each board can be connected together by inserting the mortise and tenon. The mortise and tenon structure can adopt the existing technology of inserting mortise and tenon, which will not be elaborated here.

[0028] To prevent water leakage at the connections of the boards of the main cabin, after placing the electronic components in the main cabin, when inserting the boards to form the main cabin, the connections can be sealed with sealant or hot melt adhesive. The two sides of the bottom plate 21 at the bottom of the main cabin are respectively fixedly connected to a pair of floating barrels. When connecting, hot melt adhesive can be used to bond the bottom plate and the pair of floating barrels together. During assembly, the bottom plate and the bottoms of the pair of floating barrels can be at the same horizontal plane, while the rest of the main cabin is higher than the pair of floating barrels.

[0029] The first floating barrel in the pair of floating barrels (such as Figure 5 the left floating barrel in Figure 5 ) is installed with a front camera 3 at the front end and a rear camera 11 at the rear end. The second floating barrel in the pair of floating barrels (such as

[0030] the right floating barrel in

[0031] ) is installed with a front lighting lamp 5 at the front end and a rear lighting lamp 8 at the rear end. Through the front and rear cameras, it is convenient for students to master the water surface and underwater conditions when collecting water samples using the boat model, and when the light is poor, it is illuminated by the lighting lamps to smoothly complete the water sample collection task using the unmanned boat model. To protect each lighting lamp and camera, transparent covers are respectively installed at both ends of the pair of floating barrels. The covers can adopt the existing finished monitoring head covers purchased. During assembly, the front and rear cameras, the front and rear lighting lamps, and the covers are all connected to the floating barrels by screws (correspondingly, connection flanges can be set on the floating barrels), and sealant can be used for sealing after connection.

[0030] Solar charging panels are respectively fixedly installed above the pair of floating barrels to convert the solar light energy into electrical energy required for the operation of each electronic component on the unmanned boat, reducing pollution, saving energy and being environmentally friendly. The light energy obtained by the solar charging panels is converted into electrical energy and stored in the storage battery, and then the electrical energy of the storage battery is transmitted to each electrical component on the unmanned boat model through wires. The structure of the solar charging panel can refer to the existing technology of solar charging panels. The principle and circuit of converting the obtained light energy into electrical energy and supplying it to related electronic components can refer to the existing technology, which will not be elaborated here. During assembly, each wire should preferably be routed inside the floating barrels and the main cabin. Correspondingly, during design, wire routing holes are opened on the floating barrels and the main cabin.

[0031] A thruster is also installed on each buoy respectively. The thruster can be selectively installed above or below the corresponding buoy, and the thruster is arranged on the buoy part located at the rear side of the solar charging panel. Among them, a bolt connection structure for detachably connecting the two can be provided on the thruster and the corresponding buoy. For example, screw holes are respectively provided at the corresponding positions of the thruster and the buoy to detachably connect the two through bolts or screws; alternatively, the thruster and the corresponding buoy can be non-detachably connected together by hot melt adhesive. Preferably, the bolt connection structure is used to connect the two together, so that the thruster can be installed above or below the buoy as needed. The thruster is a thruster in the prior art that generates driving force by the rotation of blades. When the thruster is installed below the buoy, the rotation of the blades can be driven by a motor, that is, the power output shaft of the motor is connected to the blade rotating shaft (the connection structure can adopt the prior art structure and will not be elaborated here); when the thruster is installed above the buoy, the unmanned boat can travel in complex water environments such as swamps, and the blades can use the wind as the driving force. Correspondingly, the motor can be turned off to save electric energy. Of course, the blades can also be powered by the motor. The thruster can be installed at different positions on the buoy according to different water environments, so that the application range of the unmanned boat model can be wider, the driving can be safer, and the success rate of sampling the water body with complex water area hydrological conditions by the unmanned boat can be improved.

[0032] A rear winch is provided at the rear side of the main body cabin of the present utility model. During the design, a cantilever 9 extends obliquely backward and upward from the rear side of the main body cabin. The rear winch is installed at the end of the cantilever through screws. The end of the lifting rope wound on the rear winch is used to suspend a sampler (not shown in the figure) for collecting water samples. The rear winch is an electric winch driven by a motor in the prior art. When the motor rotates, it can drive the lifting rope to wind around the drum or unwind from the drum, so as to lift or lower the sampler. The power cord of the electric winch is connected to a storage battery that stores the electric energy converted by the solar charging panel. Among them, the sampler can adopt a sampling bucket, such as a water quality sampling bucket made of plexiglass.

[0033] An anemometer 12 for detecting the wind speed is provided above the main body cabin. The anemometer can be fixed by hot melt adhesive. A cantilever that extends obliquely forward is provided in front of the anemometer, and a camera 1 is fixedly installed at the end of the cantilever. Through the upper camera, the front camera, and the rear camera, high-definition imaging of the water surface and underwater scenery can be performed. Each camera adopts a prior art camera.

[0034] Furthermore, a storage bin 4 can also be provided in front of the main body cabin of the present utility model (such as Figure 4 、 Figure 5As shown in the figure, the storage bin can not only accommodate items but also exclude floating garbage on the water surface, improving the safety of the unmanned boat when used in complex water bodies. The storage bin can adopt the following structure, including: a square bin body and a storage door 41 that protrudes forward in a triangular shape and is detachably connected to the front side of the square bin body. The square bin body is composed of a bottom plate, a rear side plate, a left side plate, and a right side plate, and each plate is connected by a mortise and tenon structure, or by bolts, or fixed together with hot melt adhesive. The storage door can adopt a structure with two openable doors that form a triangle when closed. The rear ends of the two openable doors are hinged to the corresponding side plates, and the front ends of the two openable doors can be connected together by structures such as buckles; alternatively, the storage door can also adopt a structure of a single triangular door, and the two sides of the triangular door are hinged to the corresponding side plates. When the storage door is opened relative to the square bin body, floating garbage or sundries in the water can enter the square bin body; when the storage door is closed relative to the square bin body, it can break through the water surface and the sundries on the water surface through the triangle.

[0035] In addition to the above components, the unmanned boat model of the present utility model further includes a video transmitter for transmitting the videos captured by each camera to the control terminal. It can adopt a 5.8G frequency analog signal video and audio transmitter. During assembly, it can be placed in the main cabin or in the float. In addition, there is a console 13 for controlling the boat model and its components to perform corresponding actions. The console can be installed in a portable suitcase, and can control the direction and speed of the boat model, display the high-definition video transmitted by the video transmitter and the wind speed, and turn on the boat model, lighting, camera, rear winch, propeller, etc. The structures of the video transmitter and console with the above functions are easily obtained by those skilled in the art and will not be described in detail here.

[0036] Next, the process of students using the portable water sample collection unmanned boat model of the present utility model to collect water samples will be described.

[0038] 2. After bringing the unmanned boat model to the destination for water sample collection (such as a freshwater river or lake), hang a sampler on the lifting rope of the rear winch and lower the unmanned boat model into the water body.

[0039] 3. Through the console, control the rotation of the propeller blades to make the unmanned boat model travel in the water, and control the cameras (upper camera, front camera, rear camera) to transmit the images obtained during the movement of the unmanned boat model in real time.

[0040] 4. After controlling the unmanned boat model to travel to the sampling point, control the rear winch to operate, lower the sampler to the set depth, and then wait for a certain period of time (such as 1 minute) before lifting the sampler to the water surface to complete the water sample collection.

[0041] 5. Control the unmanned boat model to return to shore through the console to bring the water sample to the shore.

[0042] It should be noted that students can also bring the collected water samples back to school for water sample analysis.

[0043] In summary, the portable water sample collection unmanned boat model of the present utility model has a simple structure, is easy to carry, is easy for students to assemble, improves students' hands-on ability, enables students to combine the knowledge learned in science classes with real life, collect and even analyze water samples in different waters, and better stimulates students' learning interest. In addition, the various parts of the portable water sample collection unmanned boat model are made of easily available and inexpensive materials, greatly reducing the production cost of the unmanned boat model (for example, it can be made of plastic or wood, with an effective payload of about 8 kg. Compared with the prior art made of metal materials such as lead materials, the production cost of the boat model of this application can be controlled within a thousand yuan), which is conducive to the wide promotion and application of the boat model of the present utility model in primary and secondary school science classes.
