Embodiment 1

[0023] see Figure 1~Figure 3 , the land wing sail vehicle used for polar scientific research, including the car body frame (4), front wheels (3), rear wheels (5), servo motor (6) and steering gear (7), is characterized in that: A wing sail (2) is installed on the car body frame (4) through a wing sail connecting plate (14) and a mast (12), and is connected in rotation with a bearing (8), and the servo motor (6 ) and steering gear (7) are also installed on the car body frame (4); the upper and lower ends of two steel wire ropes (10) are respectively connected to a suspension extension rod (1) on the top of the wing sail (2) and the car body frame A suspension table (11) on (4); the lower end of the mast (12) is connected with the servo motor (6) through a coupling (9), and is driven to rotate by the servo motor (6); the wing sail ( 2) Installed on the mast (12) and rotate together with the mast (12); the servo motor (6) generates thrust under the wind force by controlling the...

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0026] The sail (2) is a rigid rigid sail supported by a single mast, which is composed of several carbon fiber tubes (13) and sail connecting plates (14) fixedly connected to the sail board (22) on the mast (12); The wing sail (2) adopts the NACA0018 airfoil, and 10 carbon fiber tubes (13) are symmetrically installed close to the left and right inner walls of the wing sail (22), and 4 carbon fiber tubes (13) are evenly distributed around the mast (12); After the wing-sail connecting plate (14) is fixed by four screws (20), it is connected with the mast (12) by a square hole shaft (21), which ensures the rigidity and strength of the wing-sail (2). The double front wheel steering transmission mechanism consists of a fixed shaft (15), a connecting rod shaft (16), two front wheel connectors (17), four rotating joints (18) and a steering gear transmission rod (19); the fixed s...

Embodiment 3

[0028] When the land wing sail car is in autonomous cruise mode, the wind speed and direction instrument installed on the car body frame (4) will detect the wind force and direction in real time. At this time, the control system will change the wind force through the servo motor (7) according to the wind force and direction. The included angle between the wing sail (2) and the wind is adjusted to the best angle of attack to provide the best driving force and ensure the speed of cruising. At the same time, the steering gear (7) will control the rotation of the front wheels (3) through the steering gear transmission rod (19) according to the trajectory planning requirements of the destination, according to the principle of the parallelogram linkage mechanism, and the left and right steering of the front wheels reaches ±45. °, and the distance between the two front wheels is short, the turning radius is small, and the distance between the rear wheels is large, which enhances the a...

Abstract

The invention discloses a land wing sail car for a polar scientific expedition. The land wing sail car for the polar scientific expedition comprises a car body frame, front wheels, rear wheels, a servo motor and a steering engine. The land wing sail car for the polar scientific expedition is characterized in that a wing sail is arranged on the car body frame through a wing sail connecting plate and a mast, and the wing sail is rotatably connected with the car body frame through a bearing, and the servo motor and the steering engine are arranged on the car body frame; the upper ends and the lower ends of two steel wire ropes are connected with a suspended cable long rod arranged on the top end of the wing sail and a suspended cable platform arranged on the car body frame respectively; the lower end of the mast is connected with the servo motor through a coupling and driven by the servo motor to rotate; the wing sail is arranged on the mast, and the wing sail rotates along with the mast; thrust is generated by the servo motor through controlling an angle of attack between the wing sail and the wind direction under the pushing of wind power, and a power source is provided for the land wing sail car; the rotation of the two front wheels is controlled by the steering engine through a front-wheel steering transmission mechanism, and the automatic course control of the land wing sail car can be achieved. The land wing sail car for the polar scientific expedition has the advantages of being simple and reliable in structure, high in expandability, high in cruising ability, and widely applied to the polar scientific expedition.

Description

technical field [0001] The invention belongs to the field of special robots, and relates to a robot, in particular to a land wing sail vehicle used for polar scientific research, which is directly driven by wind and can be used for scientific research in the unknown harsh environment of the polar region. Strong ability, large exploration space and other characteristics. Background technique [0002] Unknown regions such as the North and South Pole contain abundant natural and scientific resources. On the one hand, the ice and snow-covered areas of the North and South Poles are the largest cold source of the entire earth system and have a vital impact on the global climate; on the other hand, their rich resources attract countries all over the world to investigate and develop the North and South Poles. However, the harsh environment of the polar region, high cold and low oxygen, and extreme weather may threaten the lives of scientific research personnel at any time, whic...
