Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring device technology, specifically to an anti-interference mobile radar water level monitoring device. Background Technology
[0002] In modern water level monitoring, radar water level gauges are a type of non-contact liquid level measurement device based on the principle of microwave time domain reflection. Its core is to accurately calculate the water level by emitting electromagnetic waves and receiving the reflected signals from the liquid surface. It has advantages such as strong anti-interference, high accuracy, and maintenance-free operation.
[0003] The main components of a radar level monitoring instrument include a housing, an antenna system, and an electronic unit carrying the core algorithm. To improve the radar's anti-interference capability, a guided wave radar is often mounted on the radar antenna. The waveguide rod of the guided wave radar guides electromagnetic waves to penetrate the interference layer, thereby eliminating the influence of foam and liquid surface turbulence to a certain extent. However, commonly used radar level gauges are mainly based on fixed settings, which fixes the radar monitoring area. If a mobile device is used to move the radar level gauge for detection, the radar detection data will fluctuate and become inaccurate due to the influence of terrain. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides an implementation scheme: Commonly used radar level gauges are usually installed in a fixed manner, resulting in a fixed monitoring area. If a mobile device is used to drive the radar level gauge for patrol measurement, the device will be affected by the terrain undulations during the movement, causing it to shake and tilt. This makes the antenna 7 of the radar level gauge unstable, which in turn causes the direction of the radar beam it emits to change, ultimately resulting in significant fluctuations and a decrease in accuracy of the detection data.
[0021] According to the instruction manual Figure 1-3 As can be seen, in order to solve the problem of inaccurate data caused by terrain interference during mobile monitoring, this application discloses an anti-interference mobile radar water level monitoring device. The core of this device is the integration of a mobile platform and a radar mounting structure with attitude self-adaptation capability, which ensures that the antenna 7 can automatically maintain vertical pointing during movement. Specifically, it includes: a mobile base 1 as a mobile platform, which is driven by a power motor 2 to move at least two pairs of rollers 3; a mounting seat 4 set on the mobile base 1; and a radar water level monitoring structure mounted on the mounting seat 4.
[0022] According to the instruction manual Figure 1-3 As can be seen, the above-mentioned radar water level monitoring structure includes: a fixed base 5 connected to the mounting base 4; a radar liquid level monitor 6 body installed on the fixed base 5 as a signal processing unit, the model and working principle of the radar liquid level monitor 6 are common knowledge to those skilled in the art and therefore will not be disclosed; an antenna 7 extending from the radar liquid level monitor 6 body for transmitting and receiving radar waves, which is usually a rod-type waveguide radar antenna 7, and the antenna 7 is connected to the fixed base 5 through an adjustment adapter component.
[0023] The adjustment and adaptation component is the core of the antenna 7 attitude self-adaptation. Specifically, it includes: a rotating ring 8 installed in the rotating slot 9 of the fixed base 5, which can rotate flexibly around its own axis in the slot; and a pair of adjusting pins 10 movably connected to the inner side of the rotating ring 8. The antenna 7 of the radar liquid level monitor 6 is fixedly installed on this pair of adjusting pins 10. This means that the antenna 7 has two degrees of freedom in the horizontal direction, namely, it can rotate left and right with the rotating ring 8 as a whole, and it can swing back and forth around the axis formed by the pair of adjusting pins 10. In addition, the antenna 7 is also fitted with a counterweight block 11 with a multi-ring structure, and is fixed to the mounting plate 12 connected to the antenna 7 below by a long screw.
[0024] Example: The specific working process is as follows: When the mobile base 1 moves on uneven terrain and experiences bumps or tilts, the antenna 7 and its counterweight 11 fixed on the adjustment adapter will adaptively adjust their attitude under the action of gravity. The gravitational torque generated by the counterweight 11 will cause the antenna 7 to automatically swing around the adjustment pin 10, always keeping the center of gravity of the antenna 7 rod and the counterweight 11 at the lowest point, that is, keeping the antenna 7 rod approximately perpendicular to the horizontal plane, thereby maintaining the radar beam mainly pointing to the water surface below. The horizontal bumps or turning forces will drive the rotating ring 8 to rotate relative to each other in the rotating groove 9. This rotational freedom can absorb some of the horizontal impact, avoid structural stress caused by rigid connection or excessive sway of the antenna 7, and further assist in stabilizing the attitude of the antenna 7.
[0025] As a preferred option, the movable base 1 is a rectangular chassis, and each of its two pairs of rollers 3 is equipped with a shock absorber, such as a damper or a hydraulic shock absorber, to effectively absorb road impacts and reduce vibrations transmitted to the superstructure.
[0026] As a preferred embodiment, a mounting plate 12 is fixedly connected between the pair of adjusting pins 10, and the antenna 7 of the radar level monitor 6 is securely mounted on this mounting plate 12 with screws to ensure a reliable connection.
[0027] As a preferred option, the mounting plate 12 is further provided with an electrical connector 13, and the main body of the radar liquid level monitor 6 is mounted on the mounting base 4. The two are connected by a flexible cable 14 to ensure the continuity and reliability of the electrical connection of the antenna 7 during the adaptive adjustment process.
[0028] As a preferred option, the antenna 7 is a rod-type waveguide radar antenna 7, which is suitable for water level monitoring. The counterweight 11 has a multi-ring structure, which is evenly fitted on the outside of the antenna 7 and is firmly connected to the mounting plate 12 at the bottom through a long threaded rod, providing a stable and effective gravitational torque.
[0029] In summary, this anti-interference mobile radar water level monitoring device, through gravity-adaptive adjustment components, enables the radar antenna 7 to automatically maintain a vertical attitude during movement, effectively overcoming tilt interference caused by terrain bumps, greatly improving the stability and accuracy of mobile monitoring data. The shock absorber and flexible cable 14 further enhance the system's reliability and environmental adaptability.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
