Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1, the bamboo raft power assembly provided in this embodiment includes a TCU control main board 1, where the TCU control main board 1 is provided with an input end connected with a signal of a pressure sensor 11, so as to detect the draft of the bamboo raft through the pressure sensor 11; the TCU control main board 1 is prestored with the plane area of the bamboo raft so as to calculate the resistance of the bamboo raft by detecting the draught; and the signal output end of the TCU control main board 1 is connected with a power device 3 so as to control the power device 3 through the resistance. A buoy with certain buoyancy is connected to the detection end of the pressure sensor 11, and the magnitude of the pressure detected by the pressure sensor 11 is increased through the buoy; when passengers are added to the bamboo raft, the bamboo raft sinks so that the buoy can be subjected to larger buoyancy, and therefore the pressure detected by the pressure sensor 11 is increased, and the draft of the bamboo raft can be analyzed and calculated through the increased value. Starting after the bamboo raft is full of people, the draft of the bamboo raft can not change greatly, so that the draft only needs to be detected in the initial driving stage. Meanwhile, relevant parameters such as the plane area and the volume of the bamboo raft are preset in the TCU control main board 1, so that the resistance of the bamboo raft is roughly calculated according to the detected draft, the power of the power device 3 can be conveniently controlled according to the resistance, and the bamboo raft can run at a uniform speed. The periphery of the bamboo raft is protected less, the starting speed is not suitable to be too fast, therefore, the initial acceleration is required to be determined according to the resistance of the bamboo raft, and the condition that the bamboo raft is suddenly and quickly started and personnel fall into water is avoided.

Preferably, the input of TCU control mainboard 1 still is provided with angle sensor 8, and the bamboo raft bottom is provided with to flow to mark 9, angle sensor 8 connect in flow to mark 9 is last to detect the angle that makes its deflection under bamboo raft advancing direction and the rivers direction combined action. When the included angle between the advancing direction of the bamboo raft and the water flow direction is different, the resistance applied to the bamboo raft is different to a certain extent. The flow direction indicator 9 adopts a structure similar to a wind vane, and the water flow deflects angularly when passing through the flow direction indicator 9; the speed of the ship is generally greater than the speed of the water flow, the flow direction indicator 9 basically points to the ship traveling direction, but when the flow direction of the water flow forms a certain included angle with the ship traveling direction, a lateral offset force is generated on the flow direction indicator 9, so that a certain angle is formed between the flow direction indicator 9 and the ship traveling direction. The resistance of the bamboo raft along the water flow direction can be known through the detected angle, the larger the included angle is, the larger the resistance is, and therefore a compensation value is set to adjust the driving force of the power device 3 when the power device 3 is adjusted.

Preferably, a signal output end of the TCU control main board 1 is provided with a steering control device 4, so as to control the steering control device 4 according to a signal detected by the angle sensor 8. When the included angle between the advancing direction of the bamboo raft and the water flow direction is different, the steering control device 4 also needs to provide different driving forces for control; when the advancing direction of the bamboo raft is the same as the water flow direction, the advancing resistance of the bamboo raft is the minimum; according to the angle that angle sensor 8 detected, then control bamboo raft and adjust to the same with the rivers direction, can make bamboo raft more energy-conserving.

Preferably, a navigational speed measuring device 7 is arranged at a signal input end of the TCU control main board 1, and the navigational speed measuring device 7 detects the navigational speed of the bamboo raft to the ground through a GPS or a sound wave to transmit a navigational speed signal of the bamboo raft to the TCU control main board 1. A plurality of bamboo rafts run on the same water surface at the same time, and the bamboo rafts in different running directions have different water velocities, so that a unified reference cannot be formed; the speed of the ship to the ground can be used for judging how long the two adjacent bamboo rafts collide with each other when running at the current speed, so that the speed of the ship can be controlled in advance. By this display of the ground speed it is possible to know the time needed to travel to another vessel position and the operator can operate the control in advance, whereas the water speeds in different directions will result in the same speed but different distances traveled by the bamboo raft.

Preferably, the angle sensor 8 takes the angle of the flow direction indicator 9 parallel to the length direction of the bamboo raft as an angle of 0 °. The bamboo raft normally takes the length direction as the advancing direction, and the deviation angle between the water flow direction and the advancing direction of the bamboo raft can be conveniently measured by taking the angle as an angle of 0 degree.

Preferably, the signal input end of the TCU control main board 1 is provided with an impeller rotation speed detector 10, and the TCU control main board 1 prestores impeller radius and suction-end impeller radius parameters, so as to calculate thrust generated by the impeller through the rotation speed detected by the impeller rotation speed detector 10. The driving force is controlled through the rotating speed, the current of the motor for driving the impeller is controlled through the TCU control main board 1, the driving force of the impeller can be controlled, and therefore the speed of the bamboo raft can be controlled. The rotating speed of the impeller is detected in real time, so that whether the proper thrust is achieved can be judged. Preferably, the signal input end of the TCU control main board 1 is connected with a battery pack state management system 2, and the control end of the TCU control main board 1 is connected with the battery pack 5 to control the output current of the battery pack 5.

For the state of better control bamboo raft, TCU control mainboard 1's signal input part is connected with horizontal measuring apparatu 6 to detect bamboo raft gravity distribution condition, horizontal measuring apparatu 6 is provided with two, detects hull width direction and length direction's inclination respectively. When having a plurality of people on the bamboo raft, the personnel are located the position of difference and can influence the bamboo raft and produce the slope of different degrees, and different inclination can lead to the resistance that the bamboo raft received to be different. The horizontal measuring instrument 6 is used for detecting the inclination angles of the bamboo raft in the width direction and the length direction, so that the resistance of the bamboo raft is calculated in an auxiliary mode.
