[0043] Embodiment 1: The present invention is described in detail below with reference to the accompanying drawings. Figure 1-Figure 13 As shown, the present invention provides an environmentally friendly water resource sampling device, including a shell 1, a receiving groove 16 is arranged on the upper side of the shell 1, a sampling component 2 is rotatably arranged in the receiving groove 16, a filter plate 11 is hinged to the upper side of the receiving groove 16 through a hinge 111, a fastening screw 112 is arranged on the side of the filter plate 11 away from the hinge 111, the fastening screw 112 passes through the filter plate 11 and is threadedly connected to the shell 1 for fixing the filter plate 11, and a plurality of small holes are evenly distributed on the filter plate 11, and the small holes are used to filter water samples.

[0044] A conical head 12 is provided on the left side of the housing 1, and a head guide plate 13 is provided on the upper side and the front and rear sides of the conical head 12. Two vertical through holes 121 are provided vertically on the front and rear of the conical head 12, and a vertical propeller 122 is fixedly provided in each of the two vertical through holes 121. The two vertical propellers 122 are independently controlled. A horizontal drive cylinder 14 is provided at the front and rear of the lower right end of the housing 1, and a horizontal propeller 141 is fixedly provided in each horizontal drive cylinder 14. The two horizontal propellers 141 are independently controlled. By setting two vertical propellers 122, when the two vertical propellers 122 in the two vertical through holes 121 are accelerated at the same time, in coordination with the acceleration of the horizontal propeller 141, the conical head 12 and the shell 1 can be controlled to flip clockwise in the X-axis direction; when the two vertical propellers 122 in the two vertical through holes 121 are accelerated in the opposite direction at the same time, in coordination with the deceleration or reverse acceleration of the horizontal propeller 141, the conical head 12 and the shell 1 can be controlled to flip counterclockwise in the X-axis direction; thereby achieving fine-tuning of the posture of the shell 1.

[0045] When the rotation speeds of the two vertical propellers 122 in the two vertical through holes 121 are different or opposite, the shell 1 can be controlled to flip along the Y-axis direction; by controlling the rotation speeds of the two horizontal propellers 141 to be different, the shell 1 is subjected to different thrusts from the two horizontal propellers 141, and the shell 1 can be flipped in the Z-axis direction.

[0046] When the two vertical propellers 122 in the two vertical through holes 121 accelerate and rotate at the same time, in coordination with the deceleration of the horizontal propeller 141, the movement of the conical head 12 and the housing 1 in the Z-axis direction can be controlled; the two horizontal propellers 141 rotate at the same time, and the housing 1 can be pushed to move forward horizontally. In this way, multiple degrees of freedom of the conical head 12 and the housing 1 can be controlled, and the housing 1 can realize the steering function by rotating around the Z-axis, so that it does not need to move directly along the X-axis. In this way, the posture of the housing 1 can be controlled and the housing 1 can be pushed to the required position.

[0047] The bottom of the housing 1 is provided with a bottom filter hole 15 penetrating the housing 1, and the bottom of the housing 1 is provided with two bottom guide plates 131 parallel to the axis of the horizontal driving cylinder 14.
