Description
Technical Field
The application relates to the technical field of flow metering equipment, in particular to a large-caliber ultrasonic flowmeter.
Background
An ultrasonic flowmeter is a flowmeter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of a measured medium and the speed of sound waves in a static medium. The ultrasonic flowmeter with the caliber of DN300 or more is called a large-caliber ultrasonic flowmeter, and the large-caliber ultrasonic flowmeter is provided with a display screen for displaying the flow rate when the flowing medium passes through. Among them, a large-caliber ultrasonic flowmeter is generally used outdoors.
Because of dust in the outdoor air, the dust can fall on the display screen to influence the data collector to watch the numerical value on the display screen. Before a worker views the numerical value on the display screen, the worker needs to wipe the display screen back and forth by using a wet rag or other auxiliary wiping tools to wipe dust on the display screen. However, when the user is outdoors, he sometimes forgets to carry a wet rag or other auxiliary wiping tools, so that the user can find other tools capable of wiping dust on site, and the user is inconvenient to clean the dust on the display screen.

Detailed Description
The present application is described in further detail below in conjunction with figures 1-3.
The embodiment of the application discloses a large-caliber ultrasonic flowmeter.
Referring to fig. 1, the large-caliber ultrasonic flowmeter includes a flowmeter body 1, a flow rate display 2, and an elastic scraper assembly 3. The flow rate display 2 is mounted on the flowmeter body 1 and is used for detecting and displaying the flow rate of the flowing medium passing through the flowmeter body 1 through ultrasonic technology. The flow display 2 is provided with a display screen 21 for displaying numerical values, and the elastic scraping plate assembly 3 is installed on the flow display 2 and used for cleaning dust attached to the display screen 21.
Referring to fig. 1 and 2, the elastic scraper assembly 3 includes a scraper bar 31, a frame 32, a scraper 33, dust cleaning cotton 34, and a tension spring 35. The frame 32 is mounted on the flow display 2 by bolts, and the display screen 21 is located inside the frame 32. In another embodiment, the bezel 32 may also be mounted to the flow display 2 by a snap fit. The scraping strip 31 slides and sets up in frame 32 inside and scrapes the dust on the display screen 21, and scraper blade 33 and dust cleaning cotton 34 set up respectively in the both sides of scraping strip 31 slip direction and are used for cleaing away the dust on the display screen 21. The tension spring 35 is used for driving the sliding scraping strip 31 to automatically reset, so that dust on the display screen 21 is repeatedly scraped, and the dust cleaning effect is improved.
The side of the scraping strip 31 facing away from the display screen 21 is integrally formed with a pinching plate 36, so that a finger can pinch the pinching plate 36 to slide the scraping strip 31 when the scraping strip 31 is moved.
In this embodiment, taking the display 21 as an example, the frame 32 is a rectangular frame 32. The wiper strip 31 slides along the length direction of the frame 32. The two long frames on one side of the frame 32, which is away from the flow display 2, are provided with placing grooves 321 for placing the scraping strips 31, and two ends of the scraping strips 31 are placed in the two placing grooves 321 respectively. The inner walls of the two long frames inside the frame 32 are provided with sliding grooves 322, the sliding grooves 322 are communicated with corresponding placing grooves 321, and the sliding grooves 322 extend along the length direction of the frame 32. The wiper strip 31 enters the sliding groove 322 from the placement groove 321 and slides in the sliding groove 322.
Referring to fig. 2 and 3, the scraper 33 is glued to one side of the scraper 31 in the sliding direction by glue, and one side of the scraper 33 near the display screen 21 abuts against the display screen 21. In another embodiment, the scraper 33 is fixed to the scraper bar 31 by screws. The dust cleaning cotton 34 is glued on one side of the scraping strip 31, which is away from the scraping plate 33, through glue, and one side of the dust cleaning cotton 34, which is close to the display screen 21, is abutted against the display screen 21. Further, the scraping strip 31 is scraped off by the scraping plate 33 and further removed by the dust cleaning cotton 34 in the sliding process of the display screen 21.
Referring to fig. 2 and 3, the flow display 2 is provided with a first inclined channel 22 near the edge of the width frame of the frame 32, and the first inclined channel 22 is communicated with the inside of the frame 32. The first inclined channel 22 is located at one side of the scraping strip 31 close to the scraping plate 33, and when the scraping strip 31 drives the scraping plate 33 to slide towards the direction close to the first inclined channel 22, dust on the display screen 21 enters the first inclined channel 22 through the scraping plate and automatically falls outside the flow display 2 under the guidance of the first inclined channel 22.
The flow display 2 is provided with a second inclined channel 23 at the edge facing away from the first inclined channel 22, and the second inclined channel 23 is communicated with the inside of the frame 32. When the scraping strip 31 drives the dust cleaning cotton 34 to move towards the direction approaching to the second inclined channel 23, dust on the display screen 21 falls into the second inclined channel 23 through the dust cleaning cotton 34 and automatically falls outside the flow display 2 under the guidance of the second inclined channel 23.
Referring to fig. 2 and 3, a spring groove 323 is formed on the outer wall of the frame 32, which is close to the second inclined channel 23, and the spring groove 323 is communicated with the sliding groove 322. A baffle 324 is fixed at the notch of the spring groove 323, and the tension spring 35 is positioned in the spring groove 323. The baffle 324 has a hanging ring 325 integrally formed on a side thereof adjacent to the scraper bar 31, and the scraper bar 31 is positioned in the sliding groove 322 and has a hanging ring 325 integrally formed on a side thereof adjacent to the baffle 324. One end of the tension spring 35 is hooked on the hanging ring 325 on the baffle 324, and the other end of the tension spring 35 is hooked on the hanging ring 325 on the scraping strip 31. The wiper 31 is automatically moved in a direction approaching the second inclined passage 23 by the tension spring 35 after sliding in a direction approaching the first inclined passage 22.
The implementation principle of the large-caliber ultrasonic flowmeter provided by the embodiment of the application is as follows: when the dust on the display screen 21 needs to be cleaned, the handle plate 36 is pinched by a hand to slide the scraper 31 in a direction approaching the first inclined passage 22. When the scraping bar 31 moves in a direction approaching the first inclined passage 22, the scraping plate 33 scrapes off dust on the display screen 21, and then the dust cleaning cotton 34 cleans the dust on the display again. When the scraping strip 31 moves in a direction approaching the first inclined passage 22, dust on the display screen 21 is scraped into the first inclined passage 22 and falls outside the flow rate display 2 through the first inclined passage 22.
When the scraping strip 31 moves to the position of the first inclined channel 22 in the frame 32, the hand pinching plate 36 is loosened, the scraping strip 31 is automatically reset under the action of the tension spring 35, dust on the display screen 21 is scraped again by the dust cleaning cotton 34 and the scraping plate 33 in the resetting process of the scraping strip 31 and is scraped into the second inclined channel 23, and then the dust falls outside the flow display 2 through the second inclined channel 23.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
