Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeter equipment, in particular to a detachable flowmeter. Background Art

[0002] Measurement is the key to industrial production. Flow measurement is a component of metrology and technology, closely linked to the national economy, national defense, and scientific research. Doing this well plays a vital role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crises and increasing automation in industrial production, the importance and role of flowmeters in the national economy are even more pronounced.

[0003] Nowadays, the most commonly used ultrasonic flowmeter is the clamp-on ultrasonic flowmeter. When it is installed and used, there is no need to cut off the flow in the pipeline. It can be used immediately after being pasted, which fully reflects the characteristics of the ultrasonic flowmeter being simple to install and easy to use.

[0004] However, in addition to the ultrasonic transducer used for detection, the ultrasonic flowmeter also includes a main device, the ultrasonic flowmeter host. The host is generally fixed on the pipeline by a mounting bracket and screws. When disassembling and maintaining, tools are needed to complete the disassembly and installation of the host installed on the pipeline, which causes inconvenience in installation and disassembly. Therefore, it is necessary to design a detachable flowmeter to solve the above problem. Utility Model Content

[0005] In response to the above technical problems, the utility model provides a detachable flow meter, which installs the main unit on a mounting bracket that is easy to disassemble. Through the clamping and fixing mechanism set on the support bracket fixed at both ends of the mounting bracket, the disassembly and installation of the flow meter can be completed without the aid of tools, which is easy to operate.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A detachable flow meter, a mounting frame, a host and an ultrasonic transducer, wherein the host is mounted on the mounting frame, the host is connected to the ultrasonic transducer via a wire, and the ultrasonic transducer is arranged on a pipeline. The invention is characterized in that both sides of the lower end of the mounting frame are respectively fixed to a support frame, and the support frame is fixedly mounted on the pipeline by a clamping and fixing mechanism.

[0008] The clamping and fixing mechanism consists of a bidirectional screw, a rotary handle, a moving block and a fixed clamping block. The bidirectional screw is installed in a groove provided on the support frame through a bearing. The upper end of the bidirectional screw passes through the groove wall and is connected to the rotary handle. The two ends of the bidirectional screw are respectively threadedly connected to the moving block. The screw on the moving block fixes the fixed clamping block.

[0009] The ultrasonic transducer consists of a transmitter and a receiver. The transmitter and the receiver are arranged in relative positions and installed on the pipeline. The transmitter and the receiver are both connected to the host through wires.

[0010] Specifically, the fixing clamp is adapted to the pipeline.

[0011] Specifically, the threads arranged on both sides of the bidirectional screw rod are in opposite directions.

[0012] Beneficial effects of the utility model:

[0013] The utility model installs the main unit on a mounting frame that is easy to disassemble. The support frames fixed at both ends of the mounting frame are provided with clamping and fixing mechanisms. When disassembling, the operator only needs to turn the rotary handle to control the rotation of the bidirectional screw rod, so that the moving blocks respectively threaded at the two ends of the bidirectional screw rod move in opposite directions, thereby controlling the two fixed clamping blocks clamped on the pipeline to move away from the pipeline, thereby completing the removal operation of the main unit from the pipeline. When installing, the rotary handle is similarly operated to control the fixed clamping blocks to clamp on the pipeline to complete the fixed installation. The disassembly and installation of the flow meter can be completed without the help of tools, and the operation is convenient.

[0014] The fixed clamping block designed by the utility model is fixed on the moving block by screws. When the flow meter is installed on pipes of different diameters, it is only necessary to replace the fixed clamping block of the corresponding size, thereby enhancing practicality.

[0022] Example 1

[0023] As shown in the figure, a host 1 is installed on the mounting frame 3, and the host 1 is connected to the ultrasonic transducer 2 through a wire. The ultrasonic transducer 2 consists of a transmitter 21 and a receiver 22. The transmitter 21 and the receiver 22 are relatively installed on the pipe 100. The transmitter 21 and the receiver 22 are connected to the host 1 through a wire 7. The transmitter 21 and the receiver 22 are responsible for transmitting ultrasonic waves and receiving reflected signals. The signals are transmitted to the host, and the flow rate of the fluid can be calculated after processing by the host. The ultrasonic transducer 2 and the host 1 are both existing equipment, so they are not described in detail in this application.

[0024] The two sides of the lower end of the mounting frame 3 are respectively fixed on the supporting frame 4, and a bidirectional screw rod 52 is installed in the groove 41 of the supporting frame 4 through a bearing. The upper end of the bidirectional screw rod 52 passes through the groove wall of the groove 41 and is connected to the rotary handle 51. The threads arranged on both sides of the bidirectional screw rod 52 are in opposite directions, and the two ends of the bidirectional screw rod 52 are respectively threadedly connected to the moving block 53. The fixed clamping block 6 is fixedly installed on the moving block 53 by a screw 61, wherein the fixed clamping block 6 is adapted to the pipe 100.

[0025] Example 2

[0026] When the present invention is installed on the pipe 100, first, an appropriate fixing clamp 6 is selected according to the diameter of the pipe 100, and fixedly installed on the moving block 53 by means of screws 61. Then, the two fixing clamps 6 are arranged on the upper and lower sides of the pipe 100. The operator rotates the handle 51 to make the moving block 53, which is threaded at both ends of the bidirectional screw rod 52, move axially, thereby controlling the two fixing clamps 6 to move toward the direction of approaching the pipe 100 and clamping and fixing them on the pipe 100. This realizes the installation of the main unit 1, and the ultrasonic transducer 2 connected to the main unit 1 via the wire 7 is closely set or installed on the pipe 100 by means of a clamp or the like.

[0027] During disassembly, the operator only needs to rotate the handle 51 to control the rotation of the bidirectional screw rod 52, so that the moving blocks 53 respectively connected to the two ends of the bidirectional screw rod 52 move in opposite directions, thereby controlling the two fixed clamping blocks 6 clamped on the pipeline to move away from the pipeline 100, and thus completing the disassembly operation of the main unit 1 from the pipeline 100. Therefore, the main unit in the flow meter can be disassembled and installed without the help of tools, which is convenient to operate.

[0028] In addition, the fixed clamping block 6 in the present invention is fixed to the moving block 53 by screws 61. When the flow meter is installed on pipes of different diameters, it is only necessary to replace the fixed clamping block of the corresponding size, thereby enhancing practicality.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in this utility model is defined by the appended claims and their equivalents.
