Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency admittance level gauges, in particular to an anti-hanging material radio frequency admittance level gauge which is convenient for maintenance. Background Technique

[0002] The radio frequency admittance level gauge is a general-purpose level gauge for continuous level measurement. The product is applied to industrial and mining sites and is suitable for most application scenarios. The instrument consists of a circuit unit, an explosion-proof shell and a rod-type or cable-type sensing element. There are various models of sensors available, and the instrument can be installed as a whole or separately.

[0003] Chinese Patent with publication number CN221006490U discloses an explosion-proof radio frequency admittance level gauge. Through the telescopic spring, a mutual acting force is generated between the limit rod and the fixed rod, so that the explosion-proof shell after installation can be clamped and limited by the limit rod. The adjusting screw can position the limit rod, ensuring stability and avoiding the problem that when the existing radio frequency admittance level gauge is installed and fixed, bolts are usually directly used for installation and fixation, and the bolts are prone to looseness and falling off after long-term use, affecting the explosion-proof effect.

[0004] However, in the use of the radio frequency admittance level gauge in the above solution, structures such as the connection box located in the external environment are easily damaged by external collisions.

[0005] Therefore, it is very necessary to invent an anti-hanging material radio frequency admittance level gauge which is convenient for maintenance. Content of the Utility Model

A display 121 is fixedly arranged on one side of the connection box 12. A connection column 14 is fixedly arranged at the bottom of the first disc 1. A probe 15 is threadedly inserted at the bottom of the connection column 14. A thread groove is formed on the inner wall of the connection column 14. An external thread is fixedly arranged on the outer wall of the top of the probe 15. The external thread is adapted to the thread groove. The probe 15 is convenient for disassembly and installation, facilitating maintenance. A first C-shaped plate 17 and a second C-shaped plate 18 are fixedly arranged at the top of the first disc 1. A threaded rod 21 is rotatably arranged between the two side walls of the second C-shaped plate 18. A slider 22 is threadedly sleeved on the outer side of the threaded rod 21. The slider 22 is slidably connected with the second C-shaped plate 18. A second disc 23 is fixedly arranged on one side of the slider 22. The second disc 23 is slidably connected with the long column 11. Symmetrically distributed arc-shaped plates 29 and transparent plates 293 are slidably arranged on the top of the second disc 23. Symmetrically distributed first damping spring shock absorbers 28 are fixedly arranged on the side of each of the two arc-shaped plates 29 close to each other. The other end of the first damping spring shock absorber 28 is fixedly provided with a first square block 27. The first square block 27 is fixedly connected with the second disc 23. Symmetrically distributed second damping spring shock absorbers 292 are fixedly arranged on the side of each of the two transparent plates 293 close to each other. The other end of the second damping spring shock absorber 292 is fixedly provided with a second square block 291. The second square block 291 is fixedly connected with the second disc 23.

[0024] Further, a connection block 221 is fixedly arranged on the side of the slider 22 close to the second C-shaped plate 18. A chute 222 is formed on one side of the second C-shaped plate 18. The connection block 221 is slidably installed in the chute 222, facilitating the sliding of the slider 22.

[0025] Further, the top end of the threaded rod 21 penetrates through the second C-shaped plate 18 and a cylinder 24 is fixedly arranged at its end. A vertical plate 25 is fixedly arranged at the top of the second C-shaped plate 18. A threaded nail 26 is threadedly inserted on one side of the vertical plate 25. The threaded nail 26 is movably inserted into the cylinder 24.

[0026] Further, a plurality of circular grooves 241 are formed on the outer side of the cylinder 24. The threaded nail 26 is movably inserted into the circular grooves 241, facilitating the fixation of the cylinder 24.

[0027] Further, a short plate is fixedly arranged on the other side of the second disc 23. The short plate is slidably installed in the first C-shaped plate 17, facilitating the sliding of the second disc 23.

[0028] Further, a through groove is formed on the top of the second disc 23. The long column 11 is slidably installed in the through groove, facilitating the sliding of the second disc 23.

[0029] Furthermore, symmetrically distributed third springs 31 are fixedly arranged at the bottom of the first disc 1.

The other end of the fourth spring telescopic rod 33 is fixedly provided with a scraper 34, which is convenient for scraping the materials attached to the probe rod 15.

[0030] Working principle: When this solution is in use, first, when the connection box 12 needs to be protected, the threaded rod 21 can be rotated, thereby driving the slider 22 and the connecting block 221 to move upward, and then driving the second disc 23 to move upward, so that the arc-shaped plate 29 and the transparent plate 293 move upward to protect the connection box 12 and prevent the connection box 12 from being damaged by accidental external impacts. If a collision occurs, the arc-shaped plate 29 and the transparent plate 293 initially resist the impact, and the first damping spring shock absorber 28 and the second damping spring shock absorber 292 further absorb and dissipate the remaining impact, protecting the connection box 12 from damage to the greatest extent and improving the anti-collision ability of the connection box 12. While providing protection, the transparent plate 293 does not block the observation of the display 121.

[0031] When the probe rod 15 needs to be wiped, the rectangular block 32 can be pulled downward, thereby stretching the third springs 31, and then driving the fourth spring telescopic rod 33 and the scraper 34 to move downward. Affected by the elastic force of the fourth spring telescopic rod 33, the scraper 34 can be attached to the probe rod 15. Continuing to slide the rectangular block 32 and the scraper 34 downward, the materials on the outer side of the probe rod 15 can be scraped off, and the materials attached to the probe rod 15 can be removed to avoid material hanging.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
