[0002] Currently commonly used reciprocating pump is mostly piston pump, and the working principle is based on the reciprocating motion of piston. When the piston moves outward, the outlet check valve is closed, and the inlet check valve is opened, and the medium is sucked into the cylinder.

[0004] The working efficiency is relatively low, especially for single-piston pumps, which cannot be continuous. Although the working efficiency of double-piston pumps can reach about 80%, it is still lower than that of some other types of pumps, and the volume and weight are large, which is not convenient for moving and installing.

[0007] The piston is in the shape of a sheet, a rotating shaft is fixed beside the piston, and a limiting fork is arranged on the rotating shaft to cooperate with the cam.

[0008] Further, the inlet and the outlet can be formed in groups on the cylinder body, but not limited to one group or two groups.

[0009] Further, the rotating shaft is perpendicular to the main shaft, and the pistons are arranged in a radial pattern on the turntable.

[0010] Further, the rotating shaft is parallel to the main shaft, and the pistons are arranged in a star pattern on the turntable.

[0011] Further, a partition fan is arranged between adjacent pistons on the turntable.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model discloses a rotary motion replaces reciprocating motion, realizes the continuous work of piston, and remarkably improves work efficiency. The design of sheet-like piston and rotary motion makes the volume of whole device greatly reduce, and it is convenient to move and install.

[0039] Embodiment 1

[0040] As Figures 1 to 17 shown, the utility model discloses a side shaft type lamella piston device, the shell is installed rotatable turntable 2, and turntable 2 is rotatably connected with the shell through main shaft 4, and rotatable piston 1 is installed on turntable 2, and cam 3 is fixedly installed on the shell, and the shell circumference corresponds piston 1 and is equipped with cylinder 6 that contains the movement of piston 1, and inlet and outlet are set up on cylinder 6, and filter block 5 is arranged between inlet and outlet.

[0041] Piston 1 is lamella, and rotating shaft 12 is fixed beside piston 1, and limit fork 11 that cooperates with cam 3 is arranged on rotating shaft 12.

[0042] As Figure 4 shown, turntable 2 rotates as a whole, and the end of limit fork 11 moves along the profile of cam 3, so that rotating shaft 12 rotates to the specified angle on turntable 2, so that piston 1 passes from the crevice of filter block 5, and medium is filtered and overflowed.

[0043] Piston 1 is rotatably installed on turntable 2 through rotating shaft 12.

[0044] The inlet and outlet can be formed in groups on the cylinder body 6, but not limited to one group or two groups.

[0045] The rotation shaft 12 is perpendicular to the main shaft 4, and the pistons 1 are arranged radially on the rotating disc 2.

[0046] The adjacent pistons 1 on the rotating disc 2 can be provided with a partition 7.

[0047] Working process or working principle:

[0048] As shown in Figure 2 Figure 3 The radial arrangement of the pistons, when the rotating disc 2 rotates, the pistons 1 make a circular motion in the cylinder body 6 formed by the shell, the medium enters from the direction f2 indicated by the arrow in the figure, when the piston 1 moves to the preset outlet, the cam 3 drives the limiting fork 11 to rotate 90°, and the medium is filtered out and overflowed from the outlet in the direction f1 indicated by the arrow in the figure. After the piston 1 passes through the filter block 5, it is rotated 90° again under the action of the cam 3, and returns to the working state, enters the next cycle, and the piston 1 moves in the cylinder body 6 by revolution and rotation.

[0049] When moving, the medium is always pushed forward by the piston 1 in the cylinder body 6, which is equivalent to flowing in an ideal flow pipe, and almost no loss, the linear velocity of the piston is the flow velocity of the medium, and the area of the piston is the cross-sectional area of the flow pipe. The larger the area is, the greater the flow is. Conversely, if the medium actively enters, the kinetic energy of the medium perpendicular to the piston surface can be directly obtained, a couple moment is generated, and the actual utilization rate of wind energy and water energy is greatly improved.
