Description

Technical Field

[0001] This utility model relates to the field of hydraulic flow velocity measurement technology, specifically to a portable hydraulic flow velocity measuring instrument. Background Technology

[0002] In water conservancy project construction and hydrological monitoring, flow velocity measurement is a crucial link. By accurately measuring the flow velocity data of rivers, we can help calculate the flood discharge capacity of river channels and plan dikes and bridges. In the process of hydrological monitoring, we can analyze the changes in river flow velocity to determine the flow pattern of river water resources, and provide a scientific basis for flood control and drought relief projects and ecological assessment.

[0003] Existing technologies often have the following problems when used:

[0004] First, portable hydraulic flow velocity measuring instruments are usually fixed in structure, making it difficult to adjust the measuring length according to the measurement environment. They are not very portable and cannot adapt to the diverse water depth and flow velocity measurement environments of different rivers. Second, flow velocity measuring instruments, especially sensor-based measuring devices such as ultrasonic flow velocity meters, lack effective dust protection measures. When used outdoors, dust or water vapor and other impurities can easily adhere to the surface of the measuring instrument, affecting the measurement performance and accuracy of the flow velocity measuring instrument. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a portable hydraulic flow velocity measuring instrument, which can effectively solve the problems that the fixed structure of the measuring probe in the existing technology is difficult to adapt to the water depth and flow velocity environment of different rivers, affecting the measurement accuracy of the flow velocity measuring instrument, and the lack of effective dust protection measures for flow velocity measuring instruments, especially ultrasonic flow velocity meters and other sensor-type measuring equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a portable hydraulic flow velocity measuring instrument, including:

[0008] A bottom frame and an ultrasonic flow meter, wherein a gripping frame is fixedly connected to the outer wall of the bottom frame;

[0009] A variable pitch measurement assembly includes a ball screw rotatably connected to the inside of a base frame via a support frame, a slider threaded onto the ball screw, a telescopic frame fixedly connected to the outer wall of the slider, a transition frame fixedly connected to the end of the telescopic frame located outside the base frame, an ultrasonic flow meter fixedly installed inside the transition frame, and a variable pitch drive component fixedly installed on the outer wall of the base frame, the variable pitch drive component being used to drive the telescopic frame to telescopically move relative to the base frame;

[0010] A dustproof component is fixedly connected to the outer wall of the adapter frame, which is used to protect the ultrasonic flow meter from dust.

[0011] Furthermore, the variable pitch drive component includes a small motor fixedly installed on the outer wall of the bottom frame, the output end of the small motor passing through the side wall of the bottom frame and fixedly connected to the end of the ball screw.

[0012] Furthermore, the dustproof assembly includes two limiting slide rails fixedly connected to the outer wall of the adapter frame. A convex shaft is slidably connected to the inner side of each of the two limiting slide rails. A straight rod is fixedly connected to the outer peripheral wall of each of the two convex shafts. A dust cover is fixedly connected between the ends of the two straight rods away from the convex shafts. A silicone pad is fixedly connected to the upper surface of the adapter frame.

[0013] Furthermore, the disassembly and assembly component includes a rotating plate rotatably connected to the outer peripheral wall of the convex shaft, a threaded shaft threadedly connected to the rotating plate, an insertion hole provided on the outer wall of the adapter frame, the end of the threaded shaft near the adapter frame matching the insertion hole, and a knob fixedly connected to the end of the threaded shaft away from the adapter frame.

[0014] Furthermore, both the bottom frame and the telescopic frame are designed in a waist-drum shape, and the outer wall of the telescopic frame slides and fits against the inner wall of the bottom frame.

[0015] Furthermore, a damping plate is fixedly connected to the end of the convex shaft away from the limiting slide rail.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention incorporates a variable-distance measuring component. A small motor drives a ball screw to rotate in either the forward or reverse direction, allowing the slider to move the telescopic frame.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4A portable hydraulic flow velocity measuring instrument includes: a base frame 1, an ultrasonic flow meter 2, and a variable-distance measuring component. A grip frame 3 is fixedly connected to the outer wall of the base frame 1. The variable-distance measuring component includes a ball screw 4 rotatably connected to the inside of the base frame 1 via a support frame. A slider 5 is threaded onto the ball screw 4. A telescopic frame 6 is fixedly connected to the outer wall of the slider 5. Both the base frame 1 and the telescopic frame 6 are designed in a waist-drum shape, and the outer wall of the telescopic frame 6 slides against the inner wall of the base frame 1. A transition frame 7 is fixedly connected to the end of the telescopic frame 6 located outside the base frame 1. The wave velocity meter 2 is fixedly installed inside the adapter frame 7. A variable pitch drive component is fixedly installed on the outer wall of the bottom frame 1. The variable pitch drive component is used to drive the telescopic frame 6 to move telescopically relative to the bottom frame 1. The variable pitch drive component includes a small motor 8 fixedly installed on the outer wall of the bottom frame 1. The small motor 8 is model YY80-220-25NA-80JB3GN. The output end of the small motor 8 passes through the side wall of the bottom frame 1 and is fixedly connected to the end of the ball screw 4. A control button 9 is fixedly installed on the outer wall of the bottom frame 1. The control button 9 is electrically connected to the small motor 8.

[0028] The small motor 8 drives the ball screw 4 to rotate in the forward or reverse direction, so that the slider 5 can drive the telescopic frame 6 to move, and the telescopic frame 6 can move in and out relative to the bottom frame 1, thereby facilitating the measurement of the length of the ultrasonic flow meter 2, effectively improving the portability of the measuring instrument, and adapting to diverse measurement environments.

[0029] Specifically, the small motor 8 and the control button 9 are both coupled in a closed series circuit with an external power supply. The control button 9 includes two buttons for controlling the forward and reverse rotation of the output of the small motor 8, so that the small motor 8 can drive the ball screw 4 to rotate in the forward or reverse direction.

[0030] Specifically, the outer wall of the telescopic frame 6 can slide and fit against the inner wall of the bottom frame 1. Both the bottom frame 1 and the telescopic frame 6 are waist-shaped structures. Therefore, when the telescopic frame 6 moves telescopically relative to the bottom frame 1, the telescopic frame 6 and the slider 5 can be fully limited to ensure the stability of the telescopic movement of the telescopic frame 6.

[0031] A dustproof assembly is fixedly connected to the outer wall of the adapter frame 7. This dustproof assembly protects the ultrasonic flow meter 2 from dust. The dustproof assembly includes two limiting slide rails 10 fixedly connected to the outer wall of the adapter frame 7. A convex shaft 11 is slidably connected to the inner side of each of the two limiting slide rails 10. A damping plate 17 is fixedly connected to the end of the convex shaft 11 away from the limiting slide rail 10. Straight rods 12 are fixedly connected to the outer peripheral walls of each of the two convex shafts 11. The ends of the two straight rods 12 away from the convex shafts 11... A dust cover 13 is fixedly connected between the two parts. A silicone pad is fixedly connected to the upper end face of the adapter frame 7. The outer peripheral walls of the two convex shafts 11 are rotatably connected to disassembly and assembly components. The disassembly and assembly components include a rotating plate 14 rotatably connected to the outer peripheral wall of the convex shaft 11. A threaded shaft 15 is threaded through the rotating plate 14. An insertion hole 16 is opened on the outer wall of the adapter frame 7. The end of the threaded shaft 15 near the adapter frame 7 matches the insertion hole 16. A knob is fixedly connected to the end of the threaded shaft 15 away from the adapter frame 7.

[0032] By pushing the damping paddle 17 to drive the convex shaft 11 to move, the convex shaft 11 can slide within the limit slide rail 10 and drive the straight rod 12 and dust cover 13 to move, so that the dust cover 13 moves to cover the front of the ultrasonic flow meter 2. Then, the convex shaft 11 and dust cover 13 are reset and fixed. The dust cover 13 can be used to protect the ultrasonic flow meter 2 from dust, thereby effectively preventing dust or water vapor and other impurities from adhering to the surface of the measuring instrument, ensuring the measurement performance and measurement accuracy of the flow meter.

[0033] Specifically, the convex shaft 11 has a circular structure and can slide and rotate within the limiting slide rail 10. Therefore, when the convex shaft 11 moves, it can also rotate at a certain angle to support the rotation of the straight rod 12 and the dust cover 13, so that the dust cover 13 can cover the front of the ultrasonic flow meter 2.

[0034] The working principle of this utility model is as follows:

[0035] When using this portable hydraulic flow velocity measuring instrument, the staff holds the instrument and carries it to the measurement location. Depending on the actual measurement environment, the small motor 8 can be started by pressing the control button 9. The small motor 8 drives the ball screw 4 to rotate forward or backward, so that the slider 5 can move the telescopic frame 6. The telescopic frame 6 can move relative to the bottom frame 1, thus facilitating the measurement of the length by the ultrasonic flow meter 2.

[0036] After the flow rate measurement is completed, the convex shaft 11 can be moved by pushing the damping lever 17, so that the convex shaft 11 can slide within the limiting slide rail 10 and drive the straight rod 12 and the dust cover 13 to move, so that the dust cover 13 moves to cover the front of the ultrasonic flow meter 2. Then, the convex shaft 11 is reset, and the threaded shaft 15 is aligned with the insertion hole on the adapter frame 7. Then, the threaded shaft 15 is driven to rotate by turning the knob, so that the threaded shaft 15 is connected to the insertion hole 16, so as to limit and fix the convex shaft 11, and then fix the dust cover 13, so that the ultrasonic flow meter 2 can be conveniently protected from dust by using the dust cover 13.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
