Detailed Description
The invention is further illustrated and described below with reference to the drawings and detailed description. The technical features of the embodiments of the invention can be combined correspondingly on the premise of no mutual conflict.
As shown in fig. 1 and 2, the aquatic weed salvage ship in this embodiment includes: unmanned ship 1, grass inlet 2, conveyer pipe 3, spiral reamer 4, pivot 5, grass outlet 6, speed governing motor 7, bracing piece 8, remote operation unit 9, angle adjusting device 10, connecting rod 11, montant 12, camera 13, alarm device 14, power supply line 15, data line 16, control unit 17, power supply unit 18, vanning 19, shaft 20, speed governing bi-directional jet pump 21, upper water pipe 22, downcomer 23, rudder drive arrangement 24, connecting wire 25, rudder 26, full load induction system 27, dirt blocking net 28 and downcomer 29. The transfer pipe 3 is a hollow pipe extending from above the bow of the unmanned ship 1 to below the water surface. The lower extreme of conveyer pipe 3 is equipped with horn-shaped grass inlet 2, and the upper end is equipped with out grass mouth 6, and speed governing motor 7 passes through bracing piece 8 to be fixed on the top of conveyer pipe 3, and the pivot 5 of coaxial built-in conveyer pipe 3 passes the top of conveyer pipe 3 and links to each other with speed governing motor 7, and is equipped with spiral reamer 4 along the journey in pivot 5. The rotating shaft 5 is driven by the speed regulating motor 7 to rotate, and then the spiral reamer 4 is driven to rotate. The rotating shaft 5 and the spiral reamer 4 are continuously arranged between the grass inlet 2 and the grass outlet 6, so that waterweeds can be axially conveyed to the grass outlet 6 from the grass inlet 2 through the rotary conveying function of the spiral reamer 4, the grass outlet 6 is arranged at the downward position of the conveying pipe 3, and therefore the waterweeds can fall from the grass outlet 6 under the action of gravity. A recessed shaft 20 is arranged on the hull of the unmanned ship 1 directly below the grass outlet 6, and a grass container 19 is arranged in the shaft 20 for receiving water grass falling from the grass outlet 6. Because the angle of the conveying pipe 3 needs to be adjusted when working in different water areas, the grass inlet 2 of the water-saving type water-saving device can be contacted with water grass as much as possible, and the general best state is that the water surface of a river is just positioned at the middle position of the grass inlet 2, and the capturing area is the largest at the moment. In the present device, the adjustment of the angle is achieved by the angle adjusting device 10. One end of the connecting rod 11 is hinged to the middle of the conveying pipe 3, the other end of the connecting rod is hinged to the angle adjusting device 10, and the angle adjusting device 10 can be driven by a motor to rotate with a shaft fixed to the connecting rod 11, so that the angle of the connecting rod 11 is driven to change. For easy adjustment, the angle adjusting device 10 is fixed at the bow position of the unmanned ship 1. In addition, the blade of the spiral reamer 4 near one end of the grass inlet 2 can be arranged in a sawtooth shape so as to be convenient for winding the aquatic grass and improve the salvaging efficiency.
The power of the salvage ship is provided by a speed-regulating bi-directional jet pump 21, the speed-regulating bi-directional jet pump 21 being arranged at the upper part of the stern of the unmanned ship 1. One end of the speed-regulating bidirectional jet pump 21 is connected with an upper water pipe 22, the other end of the speed-regulating bidirectional jet pump is connected with a lower water pipe 23, and the upper water pipe 22 and the lower water pipe 23 are two water pipes for generating jet flow. To prevent clogging of the water pipes, both the ends of the water supply pipe 22 and the water drain pipe 23 may be provided with a dirt blocking net 28, i.e. a filter net. The tail end of the water supply pipe 22 is positioned below the water surface of the water area where the salvage ship is positioned, the other end of the water drain pipe 23 is communicated with the water drain hole 29 at the lower end of the bow of the unmanned ship 1, and the jet flow directions of the water supply pipe 22 and the water drain pipe 23 are parallel to the central axis direction of the ship body (namely the connecting line from the bow to the stern), and forward or backward power is provided for the ship body by sucking and jetting water. The rudder 26 is arranged below the stern water line of the unmanned ship 1 and is connected to the rudder driving device 24, and the rudder driving device 24 can be realized by adopting a motor or the like. The speed-regulating bidirectional jet pump 21 is a bidirectional jet pump capable of regulating the flow rate in the pump, and because the flow rate and the direction of the pump can be regulated, the water inlet and outlet jet directions and jet force of the water inlet pipe 22 and the water outlet pipe 23 can be switched, and the acceleration, the deceleration, the forward movement, the backward movement, the braking and the turning control of the unmanned ship 1 can be realized by matching with the turning action of the rudder 26.
When such a salvage ship is operated, the aquatic weeds are stored in the weed holding tank 19. And because no manual control is performed, whether the aquatic plants are fully loaded needs to be automatically judged, otherwise, if the aquatic plants are fully loaded, no timely alarm is performed, and danger occurs due to overload. To solve the above problems, it is necessary to install a full-load sensing device on the hull, and when the salvage ship reaches a full-load state, an alarm is accurately and timely given out, so that the risk of failure can be sufficiently reduced.

While the hemispherical pneumatic rubber ball 33 continues to sink to the preset position, the hemispherical pneumatic rubber ball 33 is pressed and deformed under the action of the water pressure, and the height is reduced, so that the lower metal sheet 32 is simultaneously contacted with the first upper metal sheet 30 and the second upper metal sheet 31. The alarm device 14 on the ship body can adopt an alarm lamp, a buzzer or an alarm signal transmitting device connected with the control unit through a data line 16, so that the alarm mode can select the modes of lighting the alarm lamp, buzzing or feeding back alarm information to the remote operation unit 9 through a wireless network, and the like, and one or a combination of a plurality of modes can be adopted. The alarm device 14 is internally provided with a power supply, the alarm device 14 is connected with two poles of the power supply through a connecting wire 25 to form a power supply circuit, and a contact switch for controlling the alarm device 14 to be started and closed is arranged on the connecting wire 25 of the power supply circuit. The contact switch consists of a first upper metal sheet 30 and a second upper metal sheet 31 which are not contacted, and in the state that the two metal sheets are not contacted, the power supply circuit of the alarm device 14 is disconnected and is in a closed state; and once the two metal sheets are in contact or communication, the power supply circuit of the alarm device 14 is communicated, and the alarm device 14 is started. Taking an alarm lamp as an example, the alarm lamp is directly connected to the anode and cathode of the power supply, one section of the power supply connecting wire 25 is disconnected, two metal sheets which are not in contact are arranged at the disconnection position, the two metal sheets are not communicated at ordinary times, the lamp is not lightened, and when the two metal sheets are communicated, the lamp is lightened to remind of full load.
In order to achieve a striking warning, the warning device 14 can be fixed by means of a vertical rod 12 standing on the deck of the unmanned ship 1. Meanwhile, a camera 13 can be installed at the top end of the vertical rod 12 to monitor the current ship body and the peripheral state.
