Description

Technical Field

[0001] This utility model relates to the field of 3D radar level measurement technology, and in particular to a 3D radar level measuring instrument. Background Technology

[0002] 3D radar level measurement is based on radar technology. It detects the position and shape of the material surface by transmitting and receiving electromagnetic waves. When these electromagnetic waves encounter the material surface, they are reflected, and some of the energy is returned and received by the radar receiver. By calculating the time difference between the transmitted pulse and the received pulse, and based on the propagation speed of electromagnetic waves, the distance to the material surface can be accurately calculated, thereby obtaining the three-dimensional distribution and volume of the material.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 7This utility model provides a 3D radar level measuring instrument, including a 3D radar level measuring instrument body 1 and a cleaning mechanism. A protective shell 2 is provided below the 3D radar level measuring instrument body 1. The cleaning mechanism includes an arc-shaped seat 3, an L-shaped rod 4, an L-shaped frame 5, and an electric push rod 6. The inner side of the arc-shaped seat 3 has a drainage groove 7, and a rubber strip 8 is provided at the bottom of the drainage groove 7. A fixing block 9 is provided at one end of the arc-shaped seat 3, and a water collection tank 10 is provided inside the fixing block 9. The bottom of the fixing block 9 is threaded. A collection bottle 11 is provided. A disc 12 is positioned above the L-shaped rod 4. A water tank 13 is mounted on the disc 12. A water pump 14 is installed inside the water tank 13. The outlet end of the water pump 14 is connected to an outlet pipe 15, which is positioned along the outer side of the L-shaped rod 4. One end of the outlet pipe 15 is connected to two diversion pipes 16. Multiple nozzles 17 are mounted on the diversion pipes 16, and these nozzles 17 extend into the drainage groove 7. A rotating shaft 18 is mounted on the L-shaped rod 4. The arc-shaped seat 3... The rubber strip 8 is positioned below the L-shaped rod 4 and abuts against the outer wall of the protective shell 2. The L-shaped rod 4 is mounted on the rotating shaft 18, and the L-shaped frame 5 is positioned at the output end of the electric push rod 6. The electric push rod 6 is positioned above the 3D radar level measuring instrument body 1 and rotates around the outer wall of the protective shell 2 via the arc-shaped seat 3. This allows the rubber strip 8 to clean the dust on the protective shell 2. Simultaneously, the nozzle 17 sprays water onto the protective shell 2 to improve the cleaning effect. The cleaned water and dust are discharged into the water collection tank 10 through the drainage channel 7 and finally collected through the collection bottle 11. This ensures that the dust and cleaning water do not fall directly to the ground, avoiding additional secondary cleaning work. This significantly reduces the time spent by workers cleaning the protective shell 2 and improves work efficiency. This method solves the technical problem that when cleaning the protective shell 2, the dust and cleaning water on the protective shell 2 fall directly to the ground, requiring secondary cleaning by workers.

[0023] The multiple nozzles 17 are arranged at an angle, with the angle of the multiple nozzles 17 facing the junction of the rubber strip 8 and the protective shell 2. By arranging the nozzles 17 at an angle and with the angle of the angle facing the junction of the rubber strip 8 and the protective shell 2, it can be ensured that the water flow can more effectively wash away the stains and dust attached to the protective shell 2, especially those stains located in corners and crevices that are difficult to clean.

[0024] Secondly, the inner side of the water collection tank 10 has an inclined surface 19, and the collection bottle 11, the water collection tank 10 and the diversion channel 7 are connected. The connected design can ensure that the sewage and stains generated during the cleaning process can flow smoothly into the collection bottle 11, avoiding secondary pollution caused by sewage dripping directly onto the ground.

[0025] Furthermore, the 3D radar level measuring instrument also includes two magnetic rings 20 and two magnetic pieces 21, and the magnetic rings 20 and the magnetic pieces 21 are adapted to each other. The two magnetic rings 20 are respectively fixedly connected to the body 1 of the 3D radar level measuring instrument and are sleeved on the outside of the body 1 of the 3D radar level measuring instrument. The two magnetic pieces 21 are respectively fixedly connected to the L-shaped rod 4 and are located on the inside of the L-shaped rod 4, and the magnetic rings 20 and the magnetic pieces 21 are adapted to each other. Through the design of the magnetic rings 20 and the magnetic pieces 21 being adapted to each other, the L-shaped rod 4 can be more easily fixed on the body 1 of the 3D radar level measuring instrument.

[0026] In addition, the 3D radar level measuring instrument also includes a support ring 22 and two support members. The support members include a support rod 23 and a support cylinder 24. The support ring 22 is fixedly connected to the L-shaped frame 5 and is located on the L-shaped frame 5. The disc 12 is slidably connected to the support ring 22 and is located on the support ring 22. The support rod 23 is slidably connected to the support cylinder 24 and is located inside the support cylinder 24. The support rod 23 is also fixedly connected to the L-shaped frame 5 and is located on one side of the L-shaped frame 5. The support cylinder 24 is fixedly connected to the 3D radar level measuring instrument body 1 and is located on the 3D radar level measuring instrument body 1, and is also located on one side of the electric push rod 6. The design of the support ring 22 provides stable support for the L-shaped frame 5 and the disc 12, ensuring the stability and safety of the cleaning mechanism during operation. At the same time, the sliding connection design of the support rod 23 and the support cylinder 24 improves the support effect on the L-shaped frame 5.

[0027] When using this invention, an external motor 25 drives the rotating shaft 18. The L-shaped rod 4 rotates around the 3D radar level measuring instrument body 1 under the action of the rotating shaft 18. Simultaneously, the water pump 14 is activated. The water pump 14 introduces cleaning water from the water tank 13 into the corresponding nozzle 17 through the outlet pipe 15 and the two branch pipes 16, and then sprays it out through the nozzle 17. The sprayed water wets the protective shell 2, thereby improving the cleaning effect, while the rubber strip 8 scrapes off the dust on the protective shell 2. At this time, the dust and water that are scraped off are discharged into the water collection tank 10 through the drainage channel 7, and then enter the collection bottle 11, thus preventing them from falling to the ground. After cleaning is completed, the electric push rod 6 is activated, which moves the L-shaped rod 4 away from the 3D radar level measuring instrument body 1, so as to avoid affecting the use of the 3D radar level measuring instrument body 1. In this way, the technical problem that when cleaning the protective shell 2, the dust and cleaning water on the protective shell 2 will fall directly to the ground, thus requiring secondary cleaning by the staff is required.

[0028] In using this utility model, the 3D radar level measuring instrument body 1 of this design is existing technology, so its structure will not be described in detail here. At the same time, when the 3D radar level measuring instrument body 1 is installed at a high place, the motor 25 can drive the arc-shaped seat 3 and the L-shaped rod 4 to reciprocate, thereby avoiding contact with the mounting frame 26.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
