It is suitable for non-contact continuous measurement of the liquid level of liquids, slurries and granular materials;

[0003] Defects of traditional radar level gauges: Some existing radar level gauges need to be installed at the container opening to measure the liquid level of the items in the container. However, since the level gauge usually does not have a nozzle installation structure, and the nozzles of the containers are usually large, after the radar level gauge is installed on the container nozzle, it will shake due to touch or other reasons, resulting in inaccurate measured liquid level data.

[0004] Therefore, there is an urgent need for a radar level gauge that can solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and solve the problem that when most existing radar level gauges are installed on containers with larger nozzles, the installation stability of the level gauge is poor, and it is easy to cause inaccurate measured liquid level data as mentioned in the above background art.

[0010] Preferably, a circular through hole adapted to the size of the limiting frame is provided inside the supporting flange. The inside of the limiting frame is a hollow structure, and the top end of the signal transmitting member is fixedly installed at the bottom end of the radar level gauge main body.

[0011] Preferably, a group of circular through holes adapted to the size of the adjusting rod are provided on the left side of the adjusting frame.

[0019] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] As Figures 1-3 shown, in the embodiment of the present utility model: A radar level gauge with a nozzle mechanism includes a radar level gauge main body 1.

[0022] In specific operation, a limit frame 2 is installed at the bottom end of the radar level gauge main body 1. A regulating frame 3 is fixedly installed on the left side of the limit frame 2. A regulating rod 301 is inserted into the left side of the regulating frame 3. One end of the regulating rod 301 is provided with a regulating knob 302, and the right end of the regulating rod 301 is provided with an output gear 303. A transmission belt 304 is installed on the surface of the output gear 303;

[0023] A connecting rod 4 is inserted into the regulating frame 3. A transmission gear 401 is installed on the surface of the connecting rod 4. The right end of the connecting rod 4 is provided with a transmission screw 402. A moving slider 5 is installed inside the limit frame 2. A moving connecting plate 501 is fixedly installed at the bottom end of the moving slider 5. A pushing slider 502 is fixedly installed at the bottom end of the moving connecting plate 501. A nozzle fixing block 503 is installed on the side of the pushing slider 502.

[0024] Through the above technical solution, by rotating the regulating knob 302, the two nozzle fixing blocks 503 can move towards the inner wall of the nozzle simultaneously, so that the two nozzle fixing blocks 503 can abut against both sides of the inner wall of the nozzle, and thus the radar level gauge main body 1 can be installed and fixed at the top end of the nozzle to ensure the stability of the radar level gauge main body 1 during installation and use.

[0025] A data display screen 101 is installed at the top end of the radar level gauge main body 1. A regulating button 102 is installed on the front surface of the radar level gauge main body 1. A set of circular grooves adapted to the size of the data display screen 101 are opened at the top end of the radar level gauge main body 1.

[0026] Through the above technical solution, the data display screen 101 can be installed at the top end of the radar level gauge main body 1. The liquid level data measured by the radar level gauge main body 1 will be displayed on the data display screen 101, and the radar level gauge main body 1 can be regulated through the regulating button 102.

[0027] The surface of the limit frame 2 is fixedly installed with a support flange 201, the bottom end of the limit frame 2 is fixedly installed with an insertion port 202, and a signal transmitter 203 is installed inside the limit frame 2.

[0028] A circular through hole adapted to the size of the limit frame 2 is provided inside the support flange 201. The inside of the limit frame 2 is a hollow structure, and the top end of the signal transmitter 203 is fixedly installed at the bottom end of the radar level gauge body 1.

[0029] Through the above technical solution, after the insertion port 202 is inserted into the container nozzle, the support flange 201 can support on the top of the nozzle, and the signal transmitter 203 can be used to transmit microwave signals into the container for liquid level detection.

[0030] A set of circular through holes adapted to the size of the adjusting rod 301 are provided on the left side of the adjusting frame 3. Tooth blocks meshing with the surface of the output gear 303 are arranged inside the transmission belt 304, and the tooth blocks arranged inside the transmission belt 304 mesh with the surface of the transmission gear 401.

[0031] A circular threaded hole adapted to the size of the transmission screw 402 is provided inside the moving slider 5. The surface of the moving slider 5 is adapted to the inner wall radian size of the limit frame 2. A push slider 502 and a nozzle fixing block 503 are connected by a round rod. A circular through hole adapted to the above round rod is provided on the side of the limit frame 2, and the nozzle fixing block 503 is adapted to the surface radian size of the limit frame 2.

[0032] Through the above technical solution, turning the adjusting knob 302 is used to drive the transmission screw 402 to rotate, which will cause the two moving sliders 5 to move in opposite directions, which will cause the nozzle fixing block 503 to move towards the inner wall of the nozzle. By using the nozzle fixing block 503 to abut against the inner wall of the nozzle, the radar level gauge body 1 can be fixedly installed at the top of the nozzle.

[0033] In summary, the working principle of the present utility model is as follows: When it is necessary to firmly install the radar level gauge main body 1 at the top of the pipe orifice for liquid level measurement, first place the radar level gauge main body 1 on the top of the container where the liquid level needs to be measured, and insert the insertion port 202 into the pipe orifice of the container. Then rotate the adjustment knob 302. By rotating the adjustment knob 302, the adjustment rod 301 can be rotated. By using the rotation of the adjustment rod 301, the output gear 303 can be rotated. By rotating the output gear 303, the transmission belt 304 can be rotated. By using the transmission belt 304, the transmission gear 401 can be driven to rotate. When the transmission gear 401 rotates, the connecting rod 4 and the transmission screw 402 will rotate together. Since the moving slider 5 will slide on the surface of the transmission screw 402 when the transmission screw 402 rotates, the two moving sliders 5 are moved towards both sides at the same time. In this way, the pushing slider 502 will move towards the inner wall of the limit frame 2, and at the same time, the pipe orifice fixing block 503 will move towards the inner wall of the container pipe orifice. The two pipe orifice fixing blocks 503 are abutted against the inner wall of the container pipe orifice. In this way, the radar level gauge main body 1 can be firmly fixed and installed at the top of the container pipe orifice by using the pipe orifice fixing block 503, so that the radar level gauge main body 1 is stably placed after installation to ensure the accuracy of the measured liquid level data measured by the radar level gauge main body 1.

[0034] The above is only the preferred embodiment of the present utility model, and it does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
