Description

Technical Field

[0001] This utility model relates to the field of radar level gauge testing, and in particular to a radar level gauge field simulation platform. Background Technology

[0002] Radar level gauges are advanced level measurement instruments based on the time-of-flight principle. They transmit high-frequency microwave pulses through an antenna system. When the pulses encounter the material surface and are reflected, they are received by a receiver inside the instrument. The position of the material surface is determined by calculating the time difference between transmission and reception, and then converted into a level signal. This non-contact measurement method allows it to adapt to complex working conditions such as high temperature, high pressure, corrosion, and dust, and it has high measurement accuracy with a resolution of up to the millimeter level.

[0003] However, existing radar test platforms are generally based on horizontally placed sliding tables. While these platforms can easily perform radar ranging tests, the testing environment is too idealized and cannot reflect the real field environment. Using tall oil and gas storage tanks for testing would waste materials and space. Furthermore, replacing the test medium with flammable liquids would waste a large amount of oil and gas resources during radar limit range tests and would also pose certain safety hazards. These issues include a large gap between the radar test platform's operation and actual application scenarios, as well as high simulation testing costs. Therefore, a radar level gauge field simulation platform is proposed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a radar level gauge field simulation platform to solve the problems mentioned in the background art, such as the large gap between the working radar test platform and the actual application scenario, and the high cost of simulation testing. The technical solution of this utility model provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A radar level gauge field simulation platform includes a support plate with a top plate at the upper end. Below the top plate is a radar fixed platform for moving a radar level gauge and a laser rangefinder. A test pipeline for simulating an oil and gas storage tank is provided outside the radar fixed platform. The test pipeline includes an extension pipe and a storage pipe. A drive mechanism for moving the radar fixed platform inside the test pipeline is provided on one side of the support plate. The drive mechanism includes a servo motor, a drive wheel, a first pulley, a second pulley, and a rope. One end of the rope is connected to the drive wheel, and the other end of the rope is wrapped around the first and second pulleys in sequence, and is also connected to the radar fixed platform.

[0007] Preferably, one end of the liquid storage tube is open, a support is provided on the outside of the liquid storage tube, the liquid storage tube is fixed on the support, and the liquid storage tube is made of transparent plastic. An inlet pipe is provided on the side of the liquid storage tube, and a drain pipe is provided on the closed end face of the liquid storage tube.

[0008] Preferably, the extension tube is made of lightweight engineering plastic, and multiple extension tubes are connected to the liquid storage tube to form an integral test pipeline, with the liquid storage tube located at the lower end of the test pipeline.

[0009] Preferably, the drive wheel is rotatably mounted on the ground, the first pulley and the second pulley are both rotatably mounted on the top plate, and the servo motor is connected to the drive wheel shaft.

[0010] Preferably, a connecting rod is provided on the radar fixing platform, the rope is connected to the radar fixing platform through the connecting rod, and a sealing ring is provided between the radar fixing platform and the test pipe, with the sealing ring fitted onto the radar fixing platform.

[0011] Preferably, both the radar level gauge and the laser rangefinder are mounted on the radar mounting platform, with the radar level gauge probe passing through the radar mounting platform and facing vertically toward the inside of the storage pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses multiple extension tubes and a storage tube to form a test pipeline, which simulates an oil and gas storage tank. After the test medium is added into the storage tube, a servo motor controls the movement of a radar fixed platform inside the test pipeline, thereby controlling the distance between the radar level gauge and the test medium, thus simulating a real-world application scenario. The length of the test pipeline can be changed by adding or removing extension tubes to simulate oil and gas storage tanks of different sizes. Compared to directly using an oil and gas storage tank for simulation testing, this invention reduces the amount of test medium required for radar level gauge limit range tests, thus lowering the simulation testing cost.

[0022] In this embodiment: Please refer to Figures 1-3 In this embodiment of the present invention, a radar level gauge field simulation platform is provided. One end of the liquid storage tube 5 is open. A bracket 501 is provided on the outside of the liquid storage tube 5, and the liquid storage tube 5 is fixed on the bracket 501. The liquid storage tube 5 is made of transparent plastic. An inlet pipe 502 is provided on the side of the liquid storage tube 5, and an outlet pipe 503 is provided on the closed end face of the liquid storage tube 5. Valves for controlling the on / off state are provided inside both the inlet pipe 502 and the outlet pipe 503. The extension tube 4 is made of lightweight engineering plastic. Multiple extension tubes 4 are connected to the liquid storage tube 5 to form an integral test pipeline. The extension tubes 4 are sealed to each other by flanges, and the extension tubes 4 are sealed to the liquid storage tube 5 by flanges. The liquid storage tube 5 is located at the lower end of the test pipeline.

[0023] A connecting rod 602 is provided on the top of the radar fixing platform 6. The rope 3 is connected to the radar fixing platform 6 through the connecting rod 602. A sealing ring 601 is provided between the radar fixing platform 6 and the test pipe. The sealing ring 601 is fitted on the radar fixing platform 6. The radar level gauge 7 and the laser rangefinder 8 are both fixedly installed on the radar fixing platform 6. The radar level gauge 7 is located at the center of the radar fixing platform 6.

The length of the test pipeline can be changed by adding or removing the extension pipe 4, which can simulate oil and gas storage tanks of different sizes. At the same time, compared with the method of directly using oil and gas storage tanks for simulation testing, the amount of test medium required when conducting the limit range test of the radar level gauge 7 is reduced, thus reducing the simulation test cost.

[0026] The laser rangefinder 8 is used to measure the moving distance of the radar level gauge 7.

[0027] The storage tube 5 has good compatibility with the test medium, which can be liquid, solid, particle or slurry, etc.

[0028] The working principle of this utility model is as follows: a test pipeline is formed by connecting multiple extension pipes 4 and a liquid storage pipe 5. The test pipeline can simulate oil and gas storage tanks of different sizes. Then, the radar fixed platform 6 is controlled by the servo motor 2 to move inside the test pipeline, thereby controlling the distance between the radar level gauge 7 and the medium to be tested. This allows for the simulation of different actual application scenarios, reduces the amount of medium to be tested, and lowers the cost of simulation testing.
