Description

Technical Field

[0001] The utility model relates to an ultrasonic measurement structure, in particular to a directional fluid pipe section type ultrasonic sensor time difference method measurement structure. Background Art

[0002] The fluid ultrasonic flow measurement system is a process control instrument that uses the principle of ultrasonic velocity difference method to detect and measure fluid flow. That is, the fluid velocity and flow rate are calculated by measuring the difference in sound velocity of the ultrasonic airflow in the forward and reverse directions.

[0003] Patent No. CN207528277U discloses an insertion type ultrasonic flow meter and flow measurement system. Although the insertion type ultrasonic flow meter has a stronger signal receiving capability and can accurately measure low flow velocity and flow rate of pipeline water, it is not convenient to install ultrasonic sensors in most cases, and the fluid flow rate is too fast and the impact force is large, which can easily cause damage to the control template. A directional fluid pipe segment ultrasonic sensor time difference measurement structure is now proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a directional fluid pipe section type ultrasonic sensor time difference method measurement structure to solve the problem that the ultrasonic sensor is difficult to install and the fluid flow rate is too fast and the impact force is too large to easily cause damage to the control template.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a directional fluid pipe segment ultrasonic sensor time difference method measurement structure is provided, including a pipeline, a mounting tube is fixedly installed on the surface of the pipeline, a placement groove is opened inside the mounting tube, a sensor is slidably connected inside the placement groove, a control box is fixedly installed on the surface of the pipeline, a control template is fixedly installed inside the control box, and the output end of the control template is electrically connected to the input end of the sensor.

[0006] Furthermore, a second magnet is slidably connected inside the placement groove, a first magnet is fixedly installed at one end of the sensor, the first magnet and the second magnet are movably fitted together, a pull rod is fixedly installed on the surface of the first magnet, and one end of the pull rod passes through the installation tube and extends to the outside.

[0007] Furthermore, a spring is fixedly mounted on the surface of the first magnet, the other end of the spring is fixedly connected to the inside of the placement slot, the pull rod passes through the inside of the spring, and a cover plate is hinged on the surface of the mounting tube.

[0008] Furthermore, a connecting rod is fixedly mounted on the surface of the control template, a rubber block is fixedly mounted on the end of the connecting rod, a sleeve is fixedly mounted inside the control box, and the rubber block and the connecting rod are both slidably connected inside the sleeve.

[0009] Furthermore, two groups of elastic members are fixedly installed inside the sleeve, and one end of the two groups of elastic members are fixedly connected to the upper surface and the lower surface of the rubber block.

[0010] Furthermore, a box door is hinged on the surface of the control box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. When installing the sensor, open the cover and pull the rod outward. The first magnet moves to the left inside the placement slot to leave space for the sensor. After the sensor is placed in the placement slot, release the rod. Under the action of the spring, squeeze the sensor to the right until the sensor probe extends into the pipe. When it needs to be taken out, pull the rod through the mutual attraction between the first magnet and the second magnet to bring the sensor into the placement slot for removal.

[0013] 2. When the fluid flows too fast and the impact force is large, the rubber block at the end of the connecting rod moves up and down inside the sleeve to rub, thereby releasing the pressure, and the elastic part plays a buffering role. Through the cooperation of the two, the control template inside the control box is prevented from being damaged by the impact force of the fluid. BRIEF DESCRIPTION OF THE DRAWINGS
