Description

Technical Field

[0001] The utility model belongs to the technical field of solid flow meters, and particularly relates to an impact-resistant flow meter. Background Art

[0002] Solid flow meters are applicable to the measurement of solid mass flow in metal enclosed pipelines within a wide range from kg / h to t / h. This system is suitable for on-line monitoring of solid flow such as pneumatic conveying or free-falling powders, dusts, small spherical, granular solids, etc. Solid flow meters, solid flow gauges, microwave flow meters, microwave solid flow detectors, microwave solid flow measuring instruments. The measuring principle of solid flow meters is based on the physical principle of the Doppler effect. The sensor generates a microwave field in the pipeline, and the microwave is reflected by the particles flowing in the pipeline. By calculating the changes in frequency and amplitude, the solid flow can be accurately measured. Non-flowing particles such as dust deposits will not be calculated. However, some existing impact-resistant solid flow meters often still have certain deficiencies during use and need to be improved.

[0003] In the Chinese patent with the publication number CN219347876U, an impact-resistant solid flow meter is mentioned, which includes a flow meter and a base. A fixed box is arranged at the bottom end of the flow meter. The fixed box is provided with a sliding component. The left and right sides of the bottom end of the sliding component respectively extend to the left and right sides of the bottom end of the fixed box and are respectively fixedly installed with sliding plates. A fixed cylinder is arranged at the top end of the base. A rack is slidably inserted into the inner cavity of the fixed cylinder. Fixing holes are respectively formed in the left and right sides of the outer wall of the rack. Fixing rods are detachably inserted into the inner cavities of the two fixing holes. The two fixing rods are respectively fixedly connected with the two sliding plates. A driving component is arranged in the inner cavity of the fixed cylinder. This impact-resistant solid flow meter solves the problem that when installing a solid flow meter, one person needs to hold it, and then another person fixes and installs the conduit with the solid flow meter, which is rather troublesome and causes waste of human resources.

[0004] However, although the above technical solution can solve the cumbersome problem of a staff member holding the flow meter with one hand and another staff member installing the conduit with the flow meter when in use, after the flow meter is placed on the whole device, the contact area between the support structure and the surface of the flow meter is small at this time, which will make the flow meter prone to tipping over. At the same time, it may be affected by external factors. Once touched, it will fall off, thereby causing damage to the solid flow meter and delaying the progress of the installation work of the solid flow meter. It has certain limitations when in use. Summary of the Utility Model

[0030] One side of the top of the movable base 1 is fixedly connected with a control panel, and the control panel is electrically connected with the servo motor 13.

[0031] Embodiment 2:

[0032] Please refer to Figures 1 to 3 As shown in the figure, two positioning cavities 17 are fixedly connected to both sides of the bottom of the lifting plate 4. The inner side wall of the positioning cavity 17 is fixedly connected with a limiting rod 18. The inner side wall of the positioning cavity 17 is fixedly connected with a second compression spring 19, and the second compression spring 19 is sleeved on the surface of the limiting rod 18. The bottom end of the second compression spring 19 is fixedly connected with a moving rod 20, and the top end of the moving rod 20 is fixedly connected with the bottom of the moving frame 5. Through the setting of the positioning cavity 17, the limiting rod 18 can be fixed inside it. Through the setting of the second compression spring 19, the moving rod 20 has a certain extrusion force. Through the setting of the moving rod 20, it can drive the moving frame 5 to move left and right. It should be noted that grooves similar to the sliding grooves 21 are provided at the top and bottom of the positioning cavity 17, and the surface of the moving rod 20 penetrates into the inside of it, facilitating the left and right movement of the moving rod 20, and thus facilitating the left and right movement of the moving frame 5.

[0033] The working principle of the utility model is as follows: the staff moves the movable base 1 to the appropriate position in advance, and then the staff picks up the solid flow meter body 3 and places it on the position above the lifting plate 4, and then the staff uses the other hand to push the bottom end of one of the moving rods 20, so that one of the moving rods 20 moves in the direction where the two moving rods 20 are separated, thereby making one of the arc-shaped clamping plates 7 and the other arc-shaped clamping plate 7 farther and farther away from each other. At this time, the staff puts the solid flow meter body 3 into the position between the two arc-shaped clamping plates 7. When the solid flow meter body 3 enters the position between the two arc-shaped clamping plates 7, the staff stops pushing the moving rod 20 again, and then the second compression spring 19 is reset, so that it continuously pushes the moving rod 20 forward, thereby making the two arc-shaped clamping plates 7 approach each other, and then clamps the solid flow meter body 3. When the solid flow meter body 3 enters the interior of the arc-shaped clamping plate 7, the extrusion roller 12 is squeezed, and then the rolling frame 11 is stressed, so that it pushes the extrusion rod 10 upward, thereby making the extrusion rod 10 pass The first compression spring 9 is squeezed by the connecting block, so that the squeezing roller 12 moves upward a distance, freeing up a certain space for the entry of the solid flow meter body 3. When it is subsequently connected to one of the externally connected pipes, the staff only needs to pull the solid flow meter body 3 in the direction to be connected, so that it rolls a certain distance through the squeezing of the squeezing roller 12 to ensure stability during pulling. After the solid flow meter body 3 is fixed, the staff can control the servo motor 13 to start, and the output end of the servo motor 13 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 drives the threaded sleeve 15 on its surface to move upward until it moves to an appropriate height. After the solid flow meter body 3 is connected to the external pipe, the staff can push the two moving rods 20 in the direction of separation, and then move the moving frame 5 in the direction of separation, so that the arc clamping plate 7 stops clamping the solid flow meter body 3. At the same time, the staff controls the servo motor 13 to reverse, so that the lifting plate 4 can be lowered, so that the solid flow meter body 3 is separated from the movable base 1 as a whole.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
