Description

Technical Field

[0001] The utility model relates to the technical field of river flow detection, in particular to an integrated radar flow meter. Background Art

[0002] When the radar flow meter is working, it will send electromagnetic waves to the water surface. When the electromagnetic waves encounter the moving water surface, they will be scattered and form echoes. Since the received echo frequency is offset relative to the transmitting frequency, the water surface velocity can be obtained by the Doppler frequency equation. A moving target will generate a low-frequency output signal in the radar sensor. The frequency of this signal depends on the moving speed, and the amplitude depends on the distance, reflectivity and size of the moving target. It can be seen that the horizontal angle of the radar flow meter is extremely important and directly affects the flow rate and water level measurement effect.

[0003] Radar flowmeters are generally installed above the river, and it is necessary to ensure that the front of the radar flowmeter faces the upstream of the river and the back faces the downstream of the river. In order to enable the radar flowmeter to be located above the water flow, a crossbar is generally used to extend the radar flowmeter above the river; on this basis, there are generally two installation scenarios: bridge installation and riverbank installation; when the radar flowmeter is installed on the bridge, since the extension direction of the bridge is perpendicular to the direction of the water flow, in order to meet the installation requirements, one end of the crossbar is fixed on the bridge, so that the other end of the crossbar is usually set toward the upstream of the river and fixed to the back of the radar flowmeter, and then adjusted to horizontal; when the radar flowmeter is installed on the river bank, it usually also includes a vertical pole fixed on the river bank, one end of the crossbar is fixed above the vertical pole, and the other end of the crossbar is rotated to the top of the river channel and perpendicular to the direction of the water flow, and then the other end of the crossbar is fixed to the side of the radar flowmeter, and the front of the radar flowmeter faces the upstream of the river, and the back faces the downstream of the river, and then adjusted to horizontal.

[0004] However, with the increase of usage time, under the influence of many factors such as strong winds, heavy rains, wild animals, material aging, foundation settlement and displacement, the rod body will tilt, bend and other problems; specifically, when the radar flow meter is installed on a bridge, the cross bar is prone to bend downward, and when the radar flow meter is installed on the river bank, the vertical pole will tilt and the cross bar will bend downward, resulting in the radar flow meter meeting the requirements of facing the upstream of the river with the back facing the downstream of the river, but it will tilt, resulting in poor horizontality, affecting the measurement effect, and angle calibration is required to keep the radar flow meter level.

[0005] However, due to the inclination of the vertical pole and the bending of the horizontal bar, it is difficult for the staff to adjust the angle of the flow meter when it is installed on a bridge. Even if it can be adjusted, if the horizontal bar is not removed, the staff will need to lean out of the bridge, which poses a high safety hazard. If the horizontal bar is removed, the steps are cumbersome, and if the horizontal bar is replaced, the cost is high. For river installation, even if the staff can rotate the horizontal bar above the ground and adjust it to a horizontal state, after rotating the horizontal bar back above the river, it will still be found that the radar water level meter is not in a horizontal state, and it is difficult to adjust the radar water level meter to a horizontal state on the ground. If a new vertical pole is replaced, the cost is high. If it is not replaced, the staff will need to climb up the vertical pole, which poses a high safety hazard. In addition, manual adjustment still has the problem of insufficient precision. Utility Model Content

The scope of the embodiments of the present application is limited only by the appended claims.

[0040] It should be noted that when the radar flow meter of the embodiment of the utility model adopts the radar water level meter 3, the principle of the radar water level meter 3 is: the electromagnetic wave pulse is emitted through the antenna, the electromagnetic wave pulse propagates in the air and generates reflection when encountering the water surface, part of the electromagnetic wave is reflected back to the emission source for reception, and the time difference from emission to reception is recorded, and the distance from the antenna to the water surface can be calculated.

By setting a control unit, when the gyroscope 4 detects that the radar flow meter is not level, the control unit will calculate according to the data received from the gyroscope 4, and control the motor 53 to rotate forward or reverse based on the calculation result, and fine-tune the angle of the radar flow meter to adjust the radar flow meter to a horizontal state. Reduce the frequency of staff going to the site for maintenance and adjustment, and reduce maintenance costs.

[0058] 3. The bubble level 6 is provided to facilitate the initial installation of the radar flow meter and to provide a judgment basis for the subsequent calibration of the gyroscope 4.

[0059] 4. An isolation cover 56 is provided to isolate the key motor 53 and transmission part in the angle adjustment unit 5 from external radiation, water vapor, debris, animals, etc., so that the operating environment of the motor 53 and the transmission part is more stable, the service life is longer, the failure rate is lower, and the maintenance cost of the radar flowmeter is reduced.

[0060] 5. Setting up a high-definition camera 7 to collect image data at the measurement site is helpful for the administrator to understand the on-site flow measurement environment and to promptly clean up the debris in the river that affects the flow measurement. On the other hand, it can provide an additional way to judge the on-site situation when the measurement is abnormal.

[0061] 6. A 4G antenna 8 is provided so that the flow velocity, water level, angular velocity and other test data of the radar flow meter can be fed back to the remote platform, and the remote platform can remotely control the operation of the motor 53 to remotely adjust the flow meter to a horizontal level.

[0062] 7. During installation and disassembly maintenance, the parameters of the radar flow meter 2, radar water level meter 3 and motor 53 can be adjusted through the aviation connector 9, which improves the convenience of installation and maintenance of the radar flow meter. In addition, the aviation connector 9 has good waterproof performance and will not affect the waterproof performance of the radar flow meter.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
