[0030] The flow rate and pressure of ethylene in the pipeline push the scraper 43 of the cleaning mechanism 4 to move in the support pipe 41, the moving plate 44 of the scraper 43 slides along the round rod 45, the elastic assembly 46 plays a buffering and auxiliary resetting role, the moving block 48 moves forward in the limiting frame 47 with the scraper 43, the movable knob 49 slides on the limiting teeth 410, and after reaching the position, it is clamped to fix it, the scraped ethylene residues are discharged through the inclined groove of the scraper 43, and when resetting, the limiting knob 411 is pressed, the movable knob 49 is separated from the limiting teeth 410, and the scraper 43 is reset by the elastic assembly 46.

[0031] Embodiment two:

[0032] Please refer to Figures 1 to 6 The embodiment provides a technical scheme based on the embodiment one: the detector 1 is provided with heating mechanisms 3 on both sides, the heating mechanism 3 comprises a support frame 31 and a switch box 32, the inside of the support frame 31 is provided with heating fins 33 for heating, the upper part of the support frame 31 is fixedly connected with two clamping pieces 34 for fixing the pipeline 2, the switch box 32 and the heating fins 33 are electrically connected, and the two clamping pieces 34 are embeddedly connected with fixing knobs 35 for clamping;

[0034] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0035] Working principle: when working, firstly, in the production process of the chemical ethylene area, the flow rate and pressure of the ethylene flowing in the pipeline 2 push the scraper 43 in the cleaning mechanism 4 to move in the support pipe 41, the moving plate 44 fixedly connected on both sides of the scraper 43 slides stably along the circular rod 45 fixed in the support pipe 41, in this process, the elastic component 46 not only buffers the sliding of the moving plate 44, avoiding the impact on the support pipe 41 and related structures caused by the too fast moving speed of the scraper 43, but also assists the scraper 43 to return to the initial position when it needs to reset after completing the cleaning task, at the same time, the moving block 48 fixedly connected with the scraper 43 will move forward in the limiting frame 47 together with the scraper 43, the movable knob 49 rotatably connected on both sides of the moving block 48 slides on the limiting teeth 410 opened on both sides of the limiting frame 47, when the scraper 43 moves to the specified position where the ethylene residue on the detector 1 can be completely removed, the movable knob 49 is clamped into the limiting teeth 410 under the action of the torsional spring in it, so that the scraper 43 is stably kept at this position, ensuring that the ethylene residue on the surface of the detector 1 is fully scraped off, the ethylene residue is discharged from the pipeline 2 through the inclined chute specially opened on both sides of the scraper 43 under the scraping action of the scraper 43, preventing it from continuing to accumulate near the pipeline 2 and the detector 1, when the scraper 43 resets, the moving block 48 will move into the sliding slot at the end of the limiting frame 47 (as shown in Figure 5 ), since the sliding slot is higher than the limiting teeth 410, at this time, the limiting knob 411 rotatably connected on both sides of the moving block 48 is clamped into the groove on the movable knob 49 under the action of the torsional spring, so that the movable knob 49 cannot rotate, and the scraper 43 returns to the initial position under the action of the elastic component 46, at the same time, when the moving block 48 is pulled back to the initial position (as shown in Figure 4 ), the guide pipe 412 is inserted into the bottom of the circular roller 413, so that the limiting knob 411 rotates counterclockwise, and then the 413 is pulled out of the groove on the movable knob 49, so that the equipment resets and repeats the work;

[0036] In the chemical production process, if the ambient temperature is low, it may cause the physical properties of ethylene to change, such as increased viscosity, poor flowability, or even condensation, which can seriously affect the detection accuracy of the detector 1 and the normal flow of the fluid in the pipeline 2. At this time, the heating mechanism 3 arranged on both sides of the detector 1 can be activated to heat the pipeline 2 and the detector 1. The switch box 32 is opened, and the heating sheet 33 inside the support frame 31 starts to heat. The heat is transferred to the pipeline 2 and the detector 1 through heat conduction, thereby increasing the temperature of the pipeline 2 and the detector 1, effectively preventing the viscosity of ethylene from increasing or condensing due to low temperature, ensuring that the detection assembly can always be in a normal working state, ensuring the accuracy of flow detection. By adjusting the power of the heating sheet 33 or the switch box 32 control parameter, the operator can flexibly control the heating temperature according to the actual working condition and the state of ethylene to achieve the best heating effect. The pipeline 2 is connected with the external fixing device through the threaded groove 42 opened on both sides of the pipeline 2, so as to realize the stable installation of the whole detection assembly, and ensure that displacement does not occur during the production process. The clamping piece 34 of the heating mechanism 3 can tightly clamp the pipeline 2, and the fixing button 35 embedded on the clamping piece 34 is further fixed, preventing the pipeline 2 from being displaced due to fluid impact or other external forces during the production process, and ensuring the reliability and stability of the detection process.
