Description

Technical Field

[0001] This utility model relates to the field of material measurement technology, and in particular to an intrinsically safe 3D radar level scanner. Background Technology

[0002] A level scanner, also known as a level meter, uses radar to acquire information about the height of materials. It can also use 3D modeling to present data such as the shape, distribution, and volume of the material surface, and is used to monitor the level status inside a container in real time.

[0003] In environments with flammable and explosive risks, such as chemical, oil and gas, and pharmaceutical industries, the application of radar level gauges faces significant safety challenges. In these scenarios, material leaks are prone to occur, and contact with internal electronic components can easily trigger chemical reactions, leading to explosions and other serious safety accidents. Therefore, due to the complex characteristics of flammable and explosive environments, the application of existing radar level scanning technology in these fields is severely limited, making it difficult to meet the safety and stability requirements of actual production.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an intrinsically safe 3D radar level scanner, installed on the top cover of a container. It includes a radar integrated plate 11, with a flared opening 1 below the radar integrated plate 11. A flange 2 is provided between the flared opening 1 and the radar integrated plate 11. The flared opening 1 is installed below the top cover, inside the container, while the radar integrated plate 11 is installed above the top cover, outside the container. The flange 2 is installed above the opening of the top cover and a sealing ring is provided between it and the top cover. Semiconductor sensors 5 are fixedly connected to both the top surface and the ground surface of the flange 2. The semiconductor sensors 5 are used to detect the concentration difference inside and outside the container and control the power switch of the radar integrated plate 11. A grounding wire 4 is provided at one end of the radar integrated plate 11.

[0023] The specific settings and functions of this embodiment will be described in detail below. The level gauge is not limited to the state of the material and can be used for solid level monitoring. It also has the characteristics of non-contact and can be used in scenarios where the material protection requirements are high. This level scanner is installed directly above the container, specifically on the top cover of the container. Part of it is located above the top cover and outside the container, while the other part is located below the top cover and inside the container.

[0024] When the material inside the container is a flammable or explosive substance such as a chemical, oil, gas, or pharmaceutical, the safety protection of the level scanner is particularly important. The radar integrated board 11 is isolated outside the container. Since the level scanner adopts a through-type installation method, leakage is prone to occur at the top cover. A flange 2 is set to prevent material leakage, and a sealing ring is installed at the opening between the flange 2 and the top cover. Nut 7 is used to provide pre-pressure to avoid material leakage and electrical reaction with the radar integrated board 11, which could cause an explosion. At the same time, semiconductor sensors 5 are installed on both the upper and lower surfaces of the flange 2. The semiconductor sensors 5 monitor the change in material concentration difference to detect whether leakage has occurred. If the difference is lower than a certain threshold, the semiconductor sensor 5 triggers the power switch of the radar integrated board 11, causing the level scanner to automatically shut off power and avoid explosions caused by operation.

[0025] Example 2: Figure 3 and Figure 4 As shown, a lower protective shell 3 is provided on the outer wall of the radar integrated plate 11, and an upper protective shell 9 is movably connected to the top of the lower protective shell 3. The lower protective shell 3 and the upper protective shell 9 protect the radar integrated plate 11. A display screen 6 is provided on the top of the upper protective shell 9, and a protective film is provided on the surface of the display screen 6. A protective ring 10 is provided on the top of the upper protective shell 9, and a glass plate is installed at the central circular hole of the protective ring 10.

[0026] A threaded rod 8 is provided at the top of the flared mouth 1, and a thread of the same shape is provided in the top cover of the container. A nut 7 is provided at the bottom of the lower protective shell 3, and a control button 12 is provided on the outer surface of the radar integrated board 11. Heat dissipation fins are provided on the surface of the radar integrated board 11, and all wire connections of the radar integrated board 11 use explosion-proof connectors.

[0027] The overall effect of this embodiment is as follows: a display screen 6 is installed on the surface of the upper protective shell 9 to display information detected and acquired by the level scanner in real time; a protective film is installed on the surface of the display screen 6; a protective ring 10 is installed on the upper protective shell 9 and fastened to the top, and secondary protection is provided by a glass plate, which improves the protection effect of the display screen 6; a grounding wire 4 is installed at one end of the radar integrated board 11 to prevent leakage current from the radar integrated board 11 from triggering electric sparks, further reducing the harm and facilitating the realization of intrinsic safety; a lower protective shell 3 is installed on the outside of the radar integrated board 11 to provide mechanical protection for the radar integrated board 11 and extend the service life of the equipment.

[0028] The device is used and operates as follows: The intrinsically safe 3D radar level scanner is installed on the top cover of the container. The internal horn 1 receives reflected signals and transmits them to the external radar integrated board 11. The radar integrated board 11 processes the data through 3D modeling and displays the level information on the display screen 6. The flange 2 and sealing ring prevent leakage. The semiconductor sensors 5 above and below it monitor the concentration difference. When the difference is too low, the power supply to the radar integrated board 11 is cut off. The grounding wire 4 prevents leakage. The lower protective shell 3 and the upper protective shell 9 provide protection, and the whole device achieves safe monitoring.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
