Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following description will be made in conjunction with the accompanying drawings so as to be understood by those skilled in the art. The drawings illustrate only some embodiments of the invention.

Example 1: as shown in fig. 1, fig. 2 and fig. 3, a hose pump with a rotatable hose comprises a pump body (1), a coupler (2), a speed reducer (3), a control box (4) and a motor (5), the motor and the speed reducer, the coupler and the pump body are sequentially connected, the coupler is fixed on a base (6), a main shaft (8) is connected in the pump body through the coupler, a triangular transmission plate (12) is respectively installed at two ends of the main shaft, the triangular transmission plate is respectively connected with three eccentric shafts (14) through transmission bolts (13), the eccentric shafts are connected with rollers (9) through rolling bearings (15), the hose (24) is U-shaped in a shell, when the hose pump operates, the three rollers sequentially extrude the hose, and the conveying of media in the hose from an inlet (10) to an outlet (11) is realized.

Example 2: the bottom of the hose fixing rod (7) is fixed on the triangular transmission plate, the hose fixing rod and the hose are vertically staggered into 90 degrees when the hose pump operates, the hose fixing rod is mainly used for ensuring that the central line of the hose is always aligned with the central line of the roller when the hose pump is in a working state, and the hose fixing rod drives the hose to complete 90-degree rotary motion mainly through extension or compression motion when the hose pump stops working.

Example 3: as shown in fig. 4, the control box (4) includes a controller (16), a frequency converter (17), a liquid crystal display (18) and a power switch (19), and the controller includes a data acquisition module (20), a data storage module (21), a data analysis processing module (22) and a human-computer interaction module (23). The frequency converter is connected with the motor, the motor and the pressure sensor are connected with the data acquisition module, and the man-machine interaction module is connected with the liquid crystal display screen. The forward and reverse pumping function and the motor frequency conversion function of the hose pump can be realized through the control of the control box.

Example 4: the pressure sensor is arranged at the medium outlet end of the hose pump, the pressure sensor transmits pressure information to the data storage module and the data analysis processing module after measuring the outlet pressure of a medium, the data analysis processing module performs data analysis processing, the normal working pressure of the hose pump is assumed to be 0.7MPa, the medium outlet pressure is 0.65MPa when fatigue occurs on two sides of the hose, 0.65MPa is set as a pressure critical value, if the outlet pressure of the medium is lower than the set pressure value (0.65 MPa), the data analysis processing module sends a command after operation, the hose pump stops working, the hose is separated from the idler wheels, then the controller sends a next command, the hose fixing rod drives the hose to rotate, automatic adjustment of rotation of the hose in the hose pump is realized, and the specific process is as follows: the hose left and right sides respectively sets up a hose dead lever, and every row of equidistance distributes 3, and the hose dead lever is miniature electronic push-pull rod, and miniature electronic push-pull rod has three kinds of operating position: the miniature electric push-pull rod is compressed for the maximum distance, the miniature electric push-pull rod is not compressed and does not extend when the miniature electric push-pull rod is at the middle position, and the miniature electric push-pull rod extends for the maximum distance when the miniature electric push-pull rod is at the high position; the working positions of the hose fixing rod can be divided into three types, namely, left high, right low, left middle, right middle, left low and right high. As shown in fig. 5, the initial installation position of the hose fixing rod is left middle right, when a rotation command of the controller is received for the first time, the hose fixing rod on the left side performs upward extension movement, the hose fixing rod on the right side performs downward compression movement, the hose performs clockwise rotation movement, finally the hose fixing rod on the left side reaches the maximum extension position, the hose fixing rod on the right side reaches the maximum compression position, the hose rotates clockwise by 90 degrees, the movement is finished, and the hose pump is restored to the working state.
