The annular flat plate blade comprises identical arc-shaped bodies at both ends and two identical flat plates in the middle section. The casing includes a left side plate, a bottom plate and a right side plate, the left side plate and the right side plate are vertically arranged, and the bottom plate is arranged horizontally. The positioning rod is located in the middle of the front and rear direction of the casing and is installed on the bottom plate of the casing near the left side plate. The positioning rod is arranged vertically. The gap between the positioning rod and the left side plate can ensure that the annular flat blade can flexibly make a semicircle in the casing. weekly exercise. The annular flat blade is set on the positioning rod and is located inside the casing, and the annular flat blade is perpendicular to the bottom plate of the casing. The turntable is horizontally arranged above the flat blades, and guide rails, slide blocks and springs are installed on the turntable. Sliders are mounted on rails. The spring is set on the guide rail and is on the inner side of the slider. The upper end of the draw bar is installed on the slide block, the draw bar is vertically arranged, and the lower section of the draw bar is inserted in the annular flat plate blade. The main shaft is installed in the center of the turntable, the main shaft is vertically arranged above the turntable, and is installed on the support through bearings. The bracket is connected with the outer wall of the annular water tank.
所述环形平板半圆周转动机构是这样工作的：起初，环形平板叶片处于纵向最前位置，即环形平板叶片的后端内壁紧贴定位杆的后缘，环形平板叶片的前端处于最前端，环形平板叶片的左侧面紧贴外壳的左侧板的右侧面，驱动所述环形平板半圆周转动机构的动力从主轴的上端输入，从上往下俯视所述环形平板半圆周转动机构，主轴带动转盘顺时针旋转，由于牵引杆插在环形平板叶片中，滑块带动牵引杆作半圆周运动，同时带动环形平板叶片在外壳内作半圆周运动，即环形平板叶片在纵向最前位置绕定位杆转动半周后到达纵向最后位置，然后直线前行至纵向最前位置，接下来环形平板叶片又绕定位杆顺时针转动半周，然后又直线前行至纵向最前位置，即回到了起初位置。接下来周期性地继续重复上述过程。这样，环形平板叶片会连续不断地将前方的水引进外壳内然后划向后方，使水在环形水槽中循环流动。运动过程中，环形平板叶片在前面与左侧板之间快速打开而在后面与左侧板之间快速合上，产生了类似昆虫的“急张”和“相扑”运动效果，而且由于外壳和转盘的束缚，环形平板叶片在外壳内运动还产生了镜面效果，划水的效率很高，且结构简单，制作成本低。The semi-circular rotation mechanism of the annular flat plate works like this: at first, the annular flat blade is in the most forward position in the longitudinal direction, that is, the rear end inner wall of the annular flat blade is close to the trailing edge of the positioning rod, the front end of the annular flat blade is at the front end, and the annular flat blade The left side of the blade is close to the right side of the left side plate of the shell, and the power to drive the annular flat semi-circle rotation mechanism is input from the upper end of the main shaft. Looking down at the annular flat semi-circle rotation mechanism from top to bottom, the main shaft drives The turntable rotates clockwise. Since the drawbar is inserted into the ring-shaped flat blade, the slider drives the drawbar to make a semi-circular motion, and at the same time drives the ring-shaped flat blade to make a semi-circular motion in the casing, that is, the ring-shaped flat blade rotates around the positioning rod at the longitudinal front position After half a circle, it reaches the final longitudinal position, and then moves straight forward to the longitudinal front position, then the annular flat blade rotates clockwise around the positioning rod for half a circle, and then moves straight forward to the longitudinal front position, that is, it returns to the initial position. Then continue to repeat the above process periodically. In this way, the annular flat plate blades will continuously introduce the water in the front into the casing and then draw it to the rear, so that the water circulates in the annular water tank. During the movement, the ring-shaped flat blades quickly open between the front and left side panels and quickly close between the rear and left side panels, resulting in insect-like "jittery" and "sumo" movement effects, and because the shell With the restraint of the turntable, the movement of the ring-shaped flat blades in the casing also produces a mirror effect, the efficiency of paddling is high, the structure is simple, and the production cost is low.
为减少环形平板叶片在外壳中运动时环形平板叶片的底部与外壳的底板的上表面之间的摩擦，环形平板叶片的底部镶有减摩滚珠，或者在定位杆上套一个耐磨平垫片，耐磨平垫片位于外壳的底板的上表面上并垫于环形平板叶片的底部；环形平板叶片的密度在1000~1300kg/m3之间。In order to reduce the friction between the bottom of the annular flat blade and the upper surface of the bottom plate of the casing when the annular flat blade moves in the casing, the bottom of the annular flat blade is inlaid with anti-friction balls, or a wear-resistant flat gasket is placed on the positioning rod , The wear-resistant flat gasket is located on the upper surface of the bottom plate of the shell and is placed on the bottom of the annular flat blade; the density of the annular flat blade is between 1000~1300kg/m 3 .
为减小牵引杆和定位杆与环形平板叶片的内表面之间的摩擦，牵引杆和定位杆的周围都镶有减摩滚珠或滚针。In order to reduce the friction between the drawing rod and the positioning rod and the inner surface of the annular flat plate blade, anti-friction balls or needles are inlaid around the drawing rod and the positioning rod.

为使环形平板叶片能尽量按标准的半圆周运动，在转盘的上方安装一个外周为半圆形的轨道，轨道固定在支架上，在滑块的正上方安装一个导轮，导轮沿着轨道的外周滚动。In order to make the annular flat blade move as standard as possible in a semicircle, a rail with a semicircular outer circumference is installed above the turntable, the rail is fixed on the bracket, and a guide wheel is installed directly above the slider, and the guide wheel follows the track The peripheral scrolling.
为了能达到高效节能，环形平板半圆周转动机构的结构做得紧凑，使得环形平板叶片的宽度稍小于外壳的左侧板的右侧面到右侧板的左侧面之间的距离；环形平板叶片的高度稍小于转盘的下表面到外壳的底板的上表面之间的距离；转盘的下表面与左侧板和右侧板之间的间隙在2~5mm之间。In order to achieve high efficiency and energy saving, the structure of the annular flat half-circle rotation mechanism is made compact, so that the width of the annular flat blade is slightly smaller than the distance between the right side of the left side plate of the housing and the left side of the right side plate; the annular flat plate The height of the blade is slightly smaller than the distance between the lower surface of the turntable and the upper surface of the bottom plate of the housing; the gap between the lower surface of the turntable and the left and right side plates is between 2 and 5mm.
