[0002] Guided wave radar level gauge is a liquid level measuring instrument used in the chemical industry. It is a radar level gauge based on the principle of time domain reflectometry (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. When encountering the surface of the medium being measured, part of the radar level gauge pulse is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium being measured is proportional to the propagation time of the pulse between them. The liquid level height is calculated.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a guided wave radar level gauge;

[0024] It includes a guide shell 1, a liquid level meter body 7 and a positioning frame 10. The front of the guide shell 1 is provided with a No. 1 motor 5, and the output end of the No. 1 motor 5 is provided with a rotating shaft 6. The outer thread of the rotating shaft 6 is penetrated and connected with a connecting block 9, and the connecting block 9 is engaged and movably located inside the guide shell 1. The front of the positioning frame 10 is connected with a protrusion 13, and the protrusion 13 is rotatably connected to the guide shell 1. The top of the positioning frame 10 is provided with a supporting shell 14, and the top of the supporting shell 14 is connected with a No. 2 motor 15. The output end of the No. 2 motor 15 is provided with a No. 1 gear 16. The top of the guide shell 1 is provided with a No. 2 gear 17, and the No. 2 gear 17 is meshed and connected with the No. 1 gear 16.

[0025] The connecting block 9 is installed inside the guide shell 1 through interlocking movement. The guide shell 1 can perform linear limit guiding on the connecting block 9 and is threadedly connected to the connecting block 9 through the rotating shaft 6. When the No. 1 motor 5 is running, the connecting block 9 can be adjusted to move linearly inside the guide shell 1, so as to facilitate the adjustment of the detection position of the liquid level meter body 7. The support shell 14 provides space for the meshing connection between the No. 1 gear 16 and the No. 2 gear 17, and the support shell 14 provides a suitable installation height for the No. 2 motor 15. Since the No. 2 gear 17 is fixedly connected to the top of the guide shell 1, and the No. 1 gear 16 is meshed with the No. 2 gear 17, it is rotatably connected to the guide shell 1 through the protrusion 13 set on the front of the positioning frame 10. When the No. 2 motor 15 is running, the No. 1 gear 16 can drive the No. 2 gear 17 to move in a circular angle around the No. 1 gear 16, and the rotation angle of the guide shell 1 needs to be limited accordingly according to the size of the inner wall of the installation container.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a guided wave radar level gauge;

[0027] A protective shell 2 is provided on the front of the guide shell 1, and the protective shell 2 is located on the outside of the No. 1 motor 5. The front of the guide shell 1 is movably connected to the No. 1 folding plate 3, and the front of the guide shell 1 is movably connected to the No. 2 folding plate 4, and the No. 1 folding plate 3 and the No. 2 folding plate 4 are both connected to the two sides of the connecting block 9. The liquid level meter body 7 is connected and installed inside the connecting block 9, and the liquid level meter body 7 is located on one side of the guide shell 1. The display end of the liquid level meter body 7 is provided with a display component 18. The interior of the clamping frame 10 is threadedly connected with a threaded component 11, and one end of the threaded component 11 is connected to the extrusion block 12.

[0028] The protective shell 2 is arranged on the outside of the No. 1 motor 5, and the protective shell 2 can protect the outside of the No. 1 motor 5. The No. 1 folding plate 3 and the No. 2 folding plate 4 are retractable folding plastic plates. The No. 1 folding plate 3 and the No. 2 folding plate 4 follow the connecting block 9 to perform telescopic folding and movement. The No. 1 folding plate 3 and the No. 2 folding plate 4 can fold and protect the inside of the guide shell 1. The liquid level meter body 7 is a guided wave radar level meter. The guided wave radar level meter is a radar level meter based on the time domain reflection principle (TDR). The electromagnetic pulse of the radar level meter is transmitted along the steel cable or probe at the speed of light. When encountering the surface of the medium to be measured, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitting device along the same path. The distance between the transmitting device and the surface of the medium to be measured is proportional to the propagation time of the pulse therebetween. The liquid level height is calculated, and the liquid level height calculated by the level meter body 7 can be displayed through the display component 18. After the positioning frame 10 is positioned outside the container whose liquid level height needs to be detected, the positioning frame 10 can be positioned and installed on the container to be detected by applying rotational force to the threaded component 11 and the squeezing block 12.

[0029] like Figure 2 and Figure 5 As shown, a guided wave radar level gauge;

[0030] One side of the liquid level meter body 7 is connected to a No. 2 magnet 19, and the No. 2 magnet 19 is located above the display component 18.

The interior of the connecting frame 20 is connected to a No. 1 magnet 8, and the No. 1 magnet 8 is magnetically attracted to the No. 2 magnet 19. A transparent plate 21 is connected to the interior of the connecting frame 20.

[0031] It is rotatably connected to the liquid level meter body 7 through the connecting frame 20, and the No. 2 magnet 19 is set on one side of the liquid level meter body 7, and the No. 1 magnet 8 is set inside the connecting frame 20. After the connecting frame 20 and the liquid level meter body 7 are rotated to a vertical position, the No. 1 magnet 8 and the No. 2 magnet 19 are used for magnetic adsorption. The connecting frame 20 can cover and protect the display component 18 of the liquid level meter body 7. The transparent plate 21 set inside the connecting frame 20 can facilitate observation of the internal display value of the display component 18, effectively extending the service life of the display segment display component 18 of the liquid level meter body 7.

[0032] Before use, the squeezing block 12 inside the positioning frame 10 is used to position the positioning frame 10 on the container where the liquid level needs to be detected. When the No. 1 motor 5 is running, the rotating shaft 6 can adjust the connecting block 9 to move linearly inside the guide shell 1, thereby facilitating the adjustment of the detection position of the liquid level gauge body 7. Since the No. 2 gear 17 is fixedly connected to the top of the guide shell 1, and the No. 1 gear 16 is meshed with the No. 2 gear 17, the positioning frame 10 is rotatably connected to the guide shell 1 through the protrusion 13 provided on the front side. When the No. 2 motor 15 is running, the No. 1 gear 16 can drive the No. 2 gear 17 to move in a circular angle around the No. 1 gear 16, which is convenient for adjusting the detection direction of the guided wave radar level gauge according to needs, thereby effectively improving the practicality of the guided wave radar level gauge.

[0033] After rotating the connecting frame 20 and the liquid level meter body 7 to a vertical position, the No. 1 magnet 8 and the No. 2 magnet 19 are used for magnetic adsorption, and the connecting frame 20 can cover and protect the display component 18 of the liquid level meter body 7. The transparent plate 21 set inside the connecting frame 20 can facilitate observation of the internal display value of the display component 18, effectively extending the service life of the display segment display component 18 of the liquid level meter body 7.
