Description

Technical Field

[0001] The present invention relates to a paraxial thin piston device, belonging to the technical field of positive displacement pumps. Background Art

[0002] At present, the commonly used reciprocating pumps are mostly piston pumps, and their working principle is based on the reciprocating motion of the piston. When the piston moves outwards, the outlet check valve closes and the inlet check valve opens, and the medium is sucked into the cylinder. When the piston squeezes inwards, the pressure in the cylinder rises, causing the inlet check valve to close and the outlet check valve to open, and the medium is pressed into the outlet pipeline. In this way, the reciprocating motion of the piston realizes the continuous transportation of the medium. The piston pump has a relatively high head and is suitable for high-pressure and small-flow occasions.

[0003] There are at least the following technical problems in the prior art: The working efficiency is relatively low. Especially for single-piston pumps, they cannot be continuous in one forward and one backward motion. 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 they are relatively large in volume and weight, making them inconvenient to move and install. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a paraxial thin piston device, which successfully realizes the conversion of reciprocating motion into rotary motion, enabling the piston to continuously rotate forward without reciprocating, with high efficiency and small occupied space, and is especially suitable for medium and low pressure and large flow.

[0005] In the paraxial thin piston device of the present invention, a rotatable turntable is installed on the housing. The turntable is rotationally connected to the housing through a main shaft. A rotatable piston is installed on the turntable. A cam is fixedly installed on the housing. A cylinder for accommodating the movement of the piston is provided on the circumference of the housing corresponding to the piston. An inlet and an outlet are provided on the cylinder, and a filter block is provided between the inlet and the outlet. The piston is in the shape of a thin sheet, and a rotating shaft is fixed beside the piston. A limit fork for cooperating with the cam is provided on the rotating shaft.

[0006] Further, the inlets and outlets can be provided in groups on the cylinder, but are not limited to one group or two groups.

[0007] Further, the rotating shaft is perpendicular to the main shaft, and the pistons are arranged radially on the turntable.

[0008] Further, the rotating shaft is parallel to the main shaft, and the pistons are arranged in a star shape on the turntable.

[0009] Further, a partition is provided between adjacent pistons on the turntable.

[0010] Compared with the prior art, the beneficial effects of the present invention are: The present invention replaces reciprocating motion with rotary motion, achieving continuous operation of the piston and significantly improving work efficiency. The design of the flaky piston and rotary motion greatly reduces the volume of the entire device, facilitating movement and installation. The inlets and outlets can be opened in groups, and the piston arrangement is flexible and diverse, allowing for adjustment and optimization according to different working requirements. Through the ingenious cooperation of components such as cams, limit forks, and rotating shafts, the piston continuously advances in the cylinder body and the turntable continuously rotates. The entire device has a compact structure and operates smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Embodiment 1 As Figures 1 to 17 shown, in the side-axis type thin piston device of the present invention, a rotatable turntable 2 is installed on the housing. The turntable 2 is rotationally connected to the housing through the main shaft 4. A rotatable piston 1 is installed on the turntable 2. A cam 3 is fixedly installed on the housing. A cylinder block 6 for accommodating the movement of the piston 1 is provided on the circumference of the housing corresponding to the piston 1. An inlet and an outlet are opened on the cylinder block 6, and a filter block 5 is provided between the inlet and the outlet; The piston 1 is in a thin sheet shape, and a rotating shaft 12 is fixed beside the piston 1. A limit fork 11 for cooperating with the cam 3 is provided on the rotating shaft 12.

[0013] As Figure 4 shown, the turntable 2 rotates as a whole, and the end of the limit fork 11 moves along the contour of the cam 3, so that the rotating shaft 12 rotates on the turntable 2 to a specified angle, and the piston 1 passes through the gap between the filter blocks 5, and the medium is filtered and overflowed.

[0014] The piston 1 is rotationally installed on the turntable 2 through the rotating shaft 12.

[0015] The inlets and outlets can be opened in groups on the cylinder block 6, but are not limited to one group or two groups.

[0016] The rotating shaft 12 is perpendicular to the main shaft 4, and the pistons 1 are radially arranged on the turntable 2.

[0017] Partition fans 7 can be provided between adjacent pistons 1 on the turntable 2.

[0018] Working process or working principle: As Figure 2 Figure 3As shown in the figure, it is a radial arrangement of the piston. When the turntable 2 rotates, the piston 1 makes a circular motion within the cylinder block 6 formed by the housing. The inlet is provided to push the medium to enter from the direction f2 indicated by the arrow in the figure. When the piston 1 moves to the set outlet, the cam 3 toggles the limit fork 11, causing the piston 1 to rotate 90° on its own axis and pass through the gap of the filter block 5 preset beside the outlet. The medium is filtered out and overflows from the outlet in the direction f1 indicated by the arrow in the figure. After the piston 1 passes through the filter block 5, under the action of the cam 3, it rotates 90° again and resumes its working state, entering the next cycle. The piston 1 moves within the cylinder block 6 through the combination of revolution and rotation on its own axis.

[0019] During the movement, the medium is continuously pushed forward by the piston 1 within the cylinder block 6, which is equivalent to flowing within an ideal flow tube with 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 within the flow tube. The larger the area, the greater the flow rate. Conversely, if the medium enters actively, the kinetic energy of the medium perpendicular to the piston surface can be directly obtained, generating a couple moment, which greatly improves the actual utilization rate of wind energy and water energy.

[0020] Embodiment 2 As Figure 4 Figure 5 As shown in the figure, different from Embodiment 1, Embodiment 2 is an axial arrangement.

[0021] The rotating shaft 12 is parallel to the main shaft 4, and the pistons 1 are arranged in a star shape on the turntable 2.

[0022] Partition fans 7 can be provided between adjacent pistons 1 on the turntable 2.

[0023] In the present invention, the description of the directions and relative positional relationships of the structures, such as the descriptions of front, back, left, right, up, and down, do not constitute a limitation to the present invention and are only for the convenience of description.
