Description
Technical Field
[0001] The utility model relates to an ADCP vertical profile flow measuring device, belonging to the technical field of water conservancy industry monitoring. Background Art
[0002] Flow sensors are important equipment for monitoring the flow rate of rivers or channels. In the prior art, a weighted flow sensor with an anti-floating object counterweight in Chinese utility model patent CN2020222911991 has the following problems: although floating objects can fall off automatically when the weighted flow sensor is out of water, floating objects may also be hung on the sling and are not easy to fall off; when measuring the flow, the weighted flow sensor takes too long to move from the bottom of the water to the surface, and the power consumption of running up and down is too large. Acoustic Doppler current profiler (ADCP), also known as profile flow sensor, can measure flow profile without disturbing the flow field, that is, without going deep under the water surface, that is, the distribution of flow velocity in the vertical or horizontal direction, without sinking for point-by-point measurement. Chinese utility model patent CN2022208351044 discloses a river profile flow sensor structure, which includes a main body, a profile flow sensor, an upper water level sensor, a lower water level sensor, a tail rudder, a hanger and a sling. The profile flow sensor is arranged at the front of the main body, and the upper water level sensor and the lower water level sensor are arranged on the upper and lower surfaces of the profile flow sensor respectively; a hanger is arranged in the middle of the main body, the hanger is connected to the sling, and the sling is located above the water surface; a tail rudder is arranged at the tail of the main body. When in use, the heavy body is lowered by a sling. Since the manual winch cannot transfer the signal, the sling is generally lifted or lowered by an electric winch. When the body is put into the water, the water level sensor senses that the body has entered the water, the electric winch stops running, the body stops below the water surface, and the profile flow velocity detection begins. However, the sling in the above-mentioned prior art is controlled by the electric winch, and the electric winch and control system have complex structures and high costs. At the same time, the heavy weight of the body also increases its own cost and the cost of the power system of the electric winch, and complicates the system, thereby reducing reliability.

DETAILED DESCRIPTION
[0020] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.
[0021] An ADCP vertical profile flow measurement device comprises a main body 1, an ADCP vertical profile flow measurement sensor 2, a hanging cable core steel wire rope 3, a hand winch 4, a conductive slip ring 5, a monitoring host 6 and a power supply 7, wherein the hanging cable core steel wire rope 3 has a cable core, and the hand winch 4 is provided with a conductive slip ring 5; the ADCP vertical profile flow measurement sensor 2 is arranged at the front end of the main body 1, the ADCP vertical profile flow measurement sensor 2 is connected to the hand winch 4 via the hanging cable core steel wire rope 3, the upper end of the hanging cable core steel wire rope 3 is wound on the hand winch 4, the cable core of the hanging cable core steel wire rope is connected to the monitoring host 6 via the conductive slip ring 5, and the power supply 7 supplies power to the monitoring host 6; the shaft of the hand winch 4 is a hollow shaft 13, which extends to the outside of the hand winch 4, and the hollow shaft 13 outside the hand winch 4 is on A conductive slip ring 5 is provided, and the conductive slip ring 5 includes a conductive slip ring rotating part 14 and a conductive slip ring stationary part 15. The conductive slip ring rotating part 14 is fixed on the hollow shaft 13 and rotates with the hollow shaft 13. The conductive slip ring stationary part 15 is fixed on the hand-cranked winch frame 17 and is stationary. The conductive slip ring stationary part 15 is matched and connected with the conductive slip ring rotating part 14 through a brush 16; one end of the hanging cable core steel wire rope 3 penetrates into the hollow shaft 13, the cable core of the hanging cable core steel wire rope 3 is connected to the conductive slip ring rotating part 14, and the conductive slip ring stationary part 15 is connected to the monitoring host 6. The electrical signal and power supply form an electrical connection channel between the monitoring host 6, the conductive slip ring stationary part 15, the brush 16, the conductive slip ring rotating part 14 and the cable core of the hanging cable core steel wire rope 3 and each sensor on the main body 1.
[0022] An ultrasonic water depth sensor 8 is provided on the lower side of the main body, and a hanger 9 is provided in the middle of the main body; one end of the hanging cable core steel wire rope 3 is wound on the hand-cranked winch, and the other end of the hanging cable core steel wire rope 3 is connected to the hanger 9, the hanger 9 is located above the main body 1, and a tail rudder 10 is provided at the rear of the main body 1.
[0023] The main body 1 is heavy at the bottom and light at the top, with the center of gravity located at the bottom of the main body 1. The overall weight of the main body 1 (including the equipment and components installed on the main body) is slightly smaller than the buoyancy generated in the water. The main body 1 floats on the water surface, with the top of the main body 1 exposed above the water surface. The hanging cable core steel wire rope on the top of the main body 1 drags the main body. Since the center of gravity of the main body is low, the main body 1 floats on the downstream water surface in a stable posture. Under the action of the tail rudder, the ADCP vertical profile flow measurement sensor 2 faces the direction of the water flow.
[0024] The main body 1 also contains a circuit board, which is a well-known public technology in the art, including signal processing and transmission, and can be assembled by ordinary technicians in the art according to requirements. The ADCP vertical profile current measurement sensor, ultrasonic water depth sensor and the cable core of the hanging cable core steel wire rope are respectively connected to the circuit board, and the cable core of the hanging cable core steel wire rope transmits signals and provides power.
[0025] The power source 7 can be an internal lithium battery or can be powered by solar energy.
[0026] The direction of the flow measurement beam of the ADCP vertical profile flow measurement sensor is obliquely downward toward the incoming water direction.
[0027] A measuring bridge is provided on the river or a wider channel, and a hand winch and a monitoring host are arranged downstream of the measuring bridge. The hanging cable core steel wire rope 3 wound on the hand winch drags the main body 1, and the handle of the hand winch is shaken to lower the hanging cable core steel wire rope, and the main body 1 with a stable posture is lowered until it floats on the downstream water surface. The main body 1 is lowered and floats on the downstream water surface. The ultrasonic water depth sensor on the main body 1 detects the distance from the water surface to the bottom of the water, and the ADCP vertical profile flow sensor performs vertical profile flow velocity detection from the water surface to the bottom of the water. The water depth data and flow velocity data are transmitted to the moving shaft of the conductive slip ring 5 fixed on the shaft of the hand winch 4 through the cable core of the hanging cable core steel wire rope 3. The static shaft of the conductive slip ring 5 transmits the data information to the monitoring host 6, and the monitoring host calculates the flow rate of the monitoring data; because the main body 1 floats on the downstream water surface under the drag of the hanger and the cable core steel wire rope, except for the main body 1, the rest of the parts do not move. It will come into contact with floating objects in the water, so only the main body 1 is likely to be caught by the floating objects in the water. When the ADCP vertical profile flow measurement sensor at the front end of the main body 1 is caught by the floating objects in the water, under the action of the water flow, the front end of the main body caught by the floating objects in the water will automatically rotate toward the rear, and the caught floating objects will be washed away by the water flow, thereby realizing the automatic detachment of the caught floating objects; after the floating objects are automatically detached, the tail rudder of the main body 1 will rotate the ADCP vertical profile flow measurement sensor toward the front end again under the action of the water flow, automatically restoring the normal flow measurement state, thereby realizing unattended flow measurement.
[0028] The hanger 9 is hinged on the main body through a rotating hanger shaft 21. A posture sensor 22 is provided in the main body 1. After the posture sensor signal is processed, the abnormal flow measurement data after the rotation of the main body 1 will be shielded; the posture sensor 22 can realize the two-way flow measurement of the estuary tide.
[0029] When the river channel is wide, in order to ensure the flow measurement accuracy, the ADCP vertical profile flow measuring device of the present invention adopts a multi-channel configuration, and multiple ADCP vertical profile flow measuring devices are used to measure the flow of each channel at the same time. It is necessary to use a multi-channel confluence communication machine 12 to connect with the monitoring host to realize multi-channel confluence and data communication, and wired or wireless communication is adopted between each multi-channel ADCP vertical profile flow measuring device and the multi-channel confluence communication machine.
[0030] In the embodiment, the hanging cable core steel wire rope 3 is wound on the winding wheel 18 of the hand-cranked winch 4, and the winding wheel 18 is provided with a crank 19. The cable core at the end of the hanging cable core steel wire rope 3 is inserted into the hollow shaft 13 of the hand-cranked winch 4 and connected to the conductive slip ring rotating member 14. The conductive slip ring rotating member 14 includes a plurality of electrodes, which are respectively connected to a plurality of terminals on the conductive slip ring stationary member 15 through a plurality of brushes 16, and the terminals of the conductive slip ring stationary member 15 are connected to the monitoring host 6 through a connecting cable 20. The conductive slip ring rotating member 14 is fixed on the hollow shaft 13 and rotates with the hollow shaft 13. The conductive slip ring stationary member 15 is fixed on the hand-cranked winch frame 17 and is stationary. The electrical signal and power supply form an electrical connection channel between the monitoring host 6, the conductive slip ring stationary member 15, the brush 16, the conductive slip ring rotating member 14 and the cable core of the hanging cable core steel wire rope 3 and each sensor on the main body 1.
