Description

Technical Field

[0001] The invention relates to a radar, in particular to a high-frequency mobile side-scanning radar for measuring hydrological flow velocity. Background Art

[0002] The high-frequency mobile side-scan radar consists of a dedicated signal transmitter, which transmits high-frequency signal radar waves with vector flow fields to the water surface through a signal transmission feeder connected to a microstrip antenna through a signal power amplification. The real-time flow velocity of the flood in the monitored water area is measured through a dedicated computer calculation. Traditional hydrological flood measurement uses buoy measurement, handheld radio wave velocity meter measurement, radar wave measurement carried by unmanned aircraft, and remote-controlled boats equipped with ADCP to measure flow across rivers.

[0003] The defects of these technical solutions are:

[0004] 1. There are many personnel, large accuracy error, and high requirements for buoy points;

[0005] 2. The use conditions can only be limited to measurement on bridges and dams. If the above two conditions are not met, it cannot be used;

[0006] 3. Emergency short-term measurement cannot achieve real-time monitoring;

[0007] 4. When the flood flow rate is above 3m / s and there are a lot of aquatic plants and garbage, it is dangerous to measure underwater, which may easily cause the measuring equipment to be washed away by the flood and lost. Summary of the invention

[0008] In order to solve the problem of difficult flood monitoring during the flood season in my country, the purpose of the present invention is to provide a high-frequency mobile side-scan radar for real-time hydrological flow velocity measurement, which has a simple structure, is safe and convenient to use, and can perform stable detection.

[0009] To achieve the above purpose, the technical solution adopted by the present invention is: a high-frequency mobile side-scan radar for real-time hydrological flow velocity measurement, including a radar antenna cylinder body fixing base, a lifting rod cylinder body and left and right half antenna fixing brackets, the lifting rod cylinder body is supported on the radar antenna cylinder body fixing base, the left and right half antenna fixing brackets are supported on the Lei Tian antenna lifting rod of the lifting rod cylinder body, and the left and right half antenna fixing brackets are connected by antenna connecting plates and antenna fixing screws; it is characterized in that: microstrip antennas and / or Yagi antennas are arranged on the left and right half antenna fixing brackets, and the lifting rod cylinder body is supported on the Lei Tian antenna lifting rod of the lifting rod cylinder body. More than three bracket support fixing point brackets are evenly distributed on the circumference of the cylinder body side surface, the upper end of the radar antenna stabilizing diagonal brace bracket is fixed to the bracket support fixing point bracket through the support fixing point screws, the lower end of the radar antenna stabilizing diagonal brace bracket is fixed to the radar antenna ground plane fixing piece through the radar antenna fixing anchor screws, the upper end of the radar antenna oblique fixed bracket is fixedly connected to the middle part of the radar antenna stabilizing diagonal brace bracket through the radar antenna stabilizing oblique bracket screws, the lower end of the radar antenna oblique fixed bracket is fixed to the radar antenna cylinder body fixed base, and the microstrip antenna and / or Yagi antenna is connected to the radar host through the signal transmission feeder.

[0010] Furthermore, the cylinder body of the lifting rod is connected to a small air compressor air pump through an air pipe for inflation.

[0011] Furthermore, a radar data transmission antenna is provided on the radar host.

[0012] Furthermore, the small air compressor pump is connected to a vehicle power supply via a power cord.

[0013] Furthermore, a radar antenna lifting rod anti-rotation stop pin is provided on the radar antenna lifting rod.

[0014] Furthermore, the microstrip antenna and / or the Yagi antenna are arranged on the same horizontal side or different sides of the left and right half antenna fixing brackets.

[0015] The vehicle-mounted power supply is supplied to the small air compressor steam pump through the power cord to supply air to the lifting rod cylinder through the steam pipe to push the radar antenna lifting rod up, and vice versa, the air in the lifting rod cylinder is discharged, and the radar antenna lifting rod is lowered and recovered. This drives the microstrip antenna and / or Yagi antenna on the left and right half antenna fixing brackets to perform side scan monitoring, and cooperates with the oblique support of the radar antenna stable diagonal support bracket and the oblique pull connection of the radar antenna oblique fixed bracket. After the signal transmission feeder is sent to the radar host, the monitoring data is output through the radar data transmission antenna. The radar has a simple structure and can effectively take into account safety, convenient use and stable detection, and is suitable for flood monitoring during the hydrological flood season.
