Description

Technical Field

[0001] This utility model relates to the field of river flow measurement, specifically a river flow measurement device. Background Technology

[0002] An acoustic Doppler current profiler is a type of underwater acoustic current meter used to measure water velocity. It emits sound waves into the water, which are scattered by scattering bodies in the water. The echo signals returned by the scattering bodies are received, and the flow velocity is calculated by analyzing the Doppler effect frequency shift. Acoustic Doppler current profilers are also known as profile current meters. Typically, during testing, a surveying vessel is used to move the current profile of the river channel back and forth to achieve the function of a surveying team.

[0003] However, when the water flow in the river is fast, the surveying vessel is prone to deviating as it moves, which can easily lead to deviations in the surveying results. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a river flow measurement device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a river flow measurement device, including a first support column, a second support column, and a surveying vessel. A stabilization mechanism is installed on one side of the first support column. The stabilization mechanism includes a winding device and a steel cable. An anti-derailment rod is installed on the end of the steel cable away from the winding device. A guide mechanism is provided above the surveying vessel. The guide mechanism includes a limiting roller and a vertical rod. Two steel cable sleeves are installed above the ratchet disc on the outside of the steel cable. A ratchet disc is provided on the upper surface of the limiting roller. A pawl is provided on the upper surface of the surveying vessel on one side of the ratchet disc. An elastic rotating shaft is installed at one end of the pawl.

[0006] As a further embodiment of this utility model: a wire hole is provided inside the first support column on the outside of the steel cable, and a support pad is installed at the lower end of the first support column.

[0007] As a further embodiment of this utility model: a hook is installed on the side surface of the second support column corresponding to the position of the steel cable, and a speed measuring instrument is installed on the lower surface of the surveying vessel.

[0008] As a further improvement of this utility model: the anti-detachment rod is fixedly connected to the steel cable, and one end of the winding device is connected to a drive motor.

[0009] As a further embodiment of this utility model: the limiting roller is rotatably connected to the surveying vessel, and the pawl engages with the ratchet disc.

[0010] As a further improvement of this utility model, the first support column is fixedly connected to the mounting plane through the support pad.

[0011] As a further improvement of this utility model, the inner diameter of the steel cable sleeve is longer than the outer diameter of the steel cable.

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

[0013] The ratchet disc at the top can engage with the pawl to ensure that the surveying vessel can turn around on the river. The guide mechanism can also limit the movement on the outside of the steel cable, and can continue to guide and limit the movement after the surveying vessel returns. After the surveying vessel returns, the anti-derailment rod at the end of the steel cable can be completely removed, and the steel cable can be wound up and retrieved using a winding device, so as not to affect the normal navigation of the river.

[0014] By attaching the steel cable to the hook on the side surface of the second support column, when the surveying vessel moves the speedometer, the two folded steel cables, under the limiting and guiding action of the steel cable sleeve, can ensure that the vessel does not deviate significantly during movement.

Detailed Implementation

[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] like Figure 1-3 As shown, this embodiment provides a river flow measurement device, including a first support column 1, a second support column 2, and a surveying vessel 3. A stabilization mechanism 7 is installed on one side of the first support column 1. The stabilization mechanism 7 includes a winding device 701 and a steel cable 702. An anti-derailment rod 703 is installed at the end of the steel cable 702 away from the winding device 701, and the anti-derailment rod 703 is fixedly connected to the steel cable 702. A drive motor is connected to one end of the winding device 701. A guide mechanism 6 is provided above the surveying vessel 3. The guide mechanism 6 includes a limiting... The positioning roller 601 and the upright 603 are rotatably connected. The positioning roller 601 is rotatably connected to the surveying vessel 3. Two steel cable sleeves 604 are installed on the upper part of the upright 603 outside the steel cable 702. The inner diameter of the steel cable sleeve 604 is longer than the outer diameter of the steel cable 702. A ratchet disc 602 is provided on the upper surface of the positioning roller 601. A pawl 605 is provided on one side of the ratchet disc 602 on the upper surface of the surveying vessel 3. The pawl 605 engages with the ratchet disc 602. An elastic rotating shaft 606 is installed at one end of the pawl 605.

[0021] like Figure 2-3 As shown, in this embodiment, the first support column 1 has a wire hole 102 inside located outside the steel cable 702, and a support pad 101 is installed at the lower end of the first support column 1. The first support column 1 is fixedly connected to the mounting plane through the support pad 101. A hook 5 is installed on the side surface of the second support column 2 corresponding to the position of the steel cable 702. A speed measuring instrument 4 is installed on the lower surface of the surveying vessel 3.

[0022] The working principle of this utility model is as follows: Before use, a first support column 1 and a second support column 2 are respectively set on both sides of the river channel. After the support pad 101 is fixed to the installation plane with pins, the steel cable 702 is passed through the wire hole 102 inside the first support column 1, then through the inside of two steel cable sleeves 604, and the end of the steel cable 702 is passed through another wire hole 102. After installing the anti-detachment rod 703, the surveying boat 3 is moved to the other end of the river channel. The steel cable 702 is then hung in the hook 5 on the side surface of the second support column 2. When the surveying boat 3 moves the speed measuring instrument 4, the two folded steel cables 702 are guided by the limiting action of the steel cable sleeves 604 to ensure that the movement is safe. To prevent significant deviation of the vessel, and when the surveying vessel 3 moves to one end, it can be controlled to rotate and turn around inside the river channel. The steel cable sleeve 604 at the upper end of the guide mechanism 6 will be fixed on the outside of the steel cable 702, while the limiting roller 601 can rotate inside the surveying vessel 3. The ratchet disc 602 above can engage with the pawl 605 to perform unidirectional limiting, ensuring that the surveying vessel 3 can turn around on the river channel. The guide mechanism 6 can also limit the outside of the steel cable 702, and can continue to guide and limit the surveying vessel 3 after it returns. After the surveying vessel 3 returns, the anti-detachment rod 703 at the end of the steel cable 702 can be completely disassembled, and the steel cable 702 can be completely wound up and retrieved using the winding device 701, so as not to affect the normal navigation of the river channel.
