Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling equipment, in particular to an unmanned boat for sampling river water quality. Background Art

[0002] The sampling unmanned boat is a kind of boat that uses autonomous driving technology and AI intelligence to achieve fixed-point positioning and fixed-depth sampling and real-time water quality monitoring. This unmanned boat can return automatically and monitor the operating status in real time through the background APP to improve operating efficiency. It adopts a jet propeller design to prevent entanglement with objects such as aquatic plants and garbage, ensuring smooth navigation. After detecting an obstacle, the unmanned boat can automatically plan a path to avoid the obstacle or stop sailing.

[0003] Existing unmanned boats used for river water quality sampling are unable to identify whether there is garbage at the sampling location in the river during driving. During the sampling process, after the container responsible for absorbing the water sample is immersed in the water, if there is large garbage under the water surface (such as plastic paper, packaging paper, etc.), the garbage will easily block the water inlet of the container, causing the speed at which the water sample enters the container to slow down, and further, it is easy to hinder the normal implementation of the sampling operation. Utility Model Content

[0004] In response to the above problems, the present application provides an unmanned boat for sampling river water quality.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an unmanned boat for sampling river water quality, comprising a hull that can move on the water surface of the river and a water collector arranged on the outside of the hull, an interception net is provided on the outside of the water collector, and a connecting frame is provided on the top of the water collector, the connecting frame is provided with an alignment sleeve, and the alignment sleeve is provided with a support column that can move synchronously with the support column, and when the support column rises and falls, the water collector can adjust its own height.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1 , Figure 2 The unmanned boat for sampling water quality in a river shown in the figure comprises a hull 1 that can move on the surface of the river and a water collector 5 arranged outside the hull 1. The water collector 5 can move to different positions in the river with the hull 1 to perform sampling operations at designated positions. An interception net 7 is arranged outside the water collector 5. When the water collector 5 is immersed in the water surface, garbage in the river can be prevented from entering the water collector 5, effectively preventing the garbage from being stuck at the water inlet of the water collector 5 and preventing water from entering the water collector 5.

[0023] At the same time, the interception net 7 does not affect the sludge and impurities in the river channel entering the water collector 5, which improves the accuracy of the sampling work. In the subsequent detection process, the water quality state can be fully restored, effectively ensuring the reference value of the water sample.

[0024] A connecting frame 4 is provided on the top of the water collector 5, and a positioning sleeve 3 is provided on the connecting frame 4. A supporting column 2 which can move synchronously with the positioning sleeve 3 is provided. When the supporting column 2 rises and falls, the water collector 5 can adjust its own height and immerse itself in different depths in the river channel to perform sampling operations, so as to facilitate sampling operations at different depths in the river channel.

[0025] like Figure 3 As shown, the connecting frame 4 is provided with a support sleeve 6 extending to the outside of the water collector 5, and the interception net 7 is threadedly connected to the support sleeve 6. During the sampling process, the interception net 7 can be disassembled and installed according to work requirements to facilitate cleaning of the interception net 7.

[0026] like Figure 3 , Figure 4As shown, the support column 2 is provided with a plurality of equally spaced limiting holes 21 from top to bottom, and the alignment sleeve 3 is provided with a through hole 1 corresponding to the limiting hole 21. In a natural state, the through hole 1 corresponds to the bottommost limiting hole 21, and the alignment sleeve 3 is provided with a first positioning pin 8 that can penetrate the through hole 1 and the limiting hole 21. Through the operable first positioning pin 8, the water collector 5 can be disassembled and installed according to work requirements. After the sampling work is completed, the water collector 5 can be removed and the sample inside it can be transferred.

[0027] like Figure 3 , Figure 4 As shown, a fixing sleeve 9 is sleeved on the support column 2, and a second through hole corresponding to the limiting hole 21 is opened on the fixing sleeve 9. When the support column 2 moves up and down, the second through hole corresponds to the limiting hole 21 at different heights. The fixing sleeve 9 is provided with a second positioning pin 10 that can penetrate the second through hole and the limiting hole 21, so as to maintain the stability of the support column 2 adjusted to different heights.

[0028] The height adjustment of the support column 2 allows the water collector 5 to be immersed to different depths during the process of immersing in the water surface for sampling, so as to facilitate sampling operations at different depths in the river channel, and has the advantage of portable adjustment.

[0029] like Figure 1 , Figure 2 As shown, the fixing sleeve 9 is provided with a mounting crossbeam 11 which can be raised and lowered synchronously therewith, the mounting crossbeam 11 is provided with a cylinder 13 which can drive the mounting crossbeam 11 to be raised and lowered, and the hull 1 is provided with a frame 12 which can carry the cylinder 13. The cylinder 13 can control the mounting crossbeam 11 and the fixing sleeve 9 to rise and fall synchronously, so as to achieve the purpose of controlling the synchronous rise and fall of the supporting column 2 and the water extractor 5, and in the process of taking water, the water extractor 5 can be smoothly immersed in and removed from the water surface.

[0030] like Figure 5 As shown, the water inlet of the water collector 5 is arranged at its bottom, the drain outlet is arranged at its top, and a movable water inlet baffle 51 is arranged on the water inlet of the water collector 5, a drain outlet cover 54 is arranged on the drain outlet, and a water outlet pipe 53 is arranged on the side wall of the water collector 5. During the sampling process, after the water collector 5 is immersed in the water surface, the water inlet baffle 51 rises under the action of pressure, and the water inlet is opened to allow the water to smoothly enter the water collector 5. The excess water can squeeze the drain outlet cover 54, causing the drain outlet cover 54 to rise, so as to achieve the purpose of taking water at a specified depth. A rubber hose is installed on the water outlet pipe 53, and the rubber hose is clamped by a pipe clamp to keep it in a closed state. When the water collector 5 finishes taking water, the water sample inside the water collector 5 can be discharged through the water outlet pipe 53.

[0031] When the water dispenser 5 finishes taking water, the water inlet baffle 51 and the drain outlet cover 54 can be smoothly reset. In order to maintain the stability of the water inlet baffle 51 and the drain outlet cover 54, a limiting block 52 that can limit its moving stroke can be provided above the water inlet baffle 51. The limiting block 52 is arranged on the inner wall of the water dispenser 5, and the connecting frame 4 is located on the outer side of the drain outlet, which can limit the moving stroke of the drain outlet cover 54.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
