Moreover, although the technical solution proposed by the above patent technology can intercept debris through the protective grid, during the rotation of the propeller, the surface of the protective grid is very easy to absorb or hang on water plants and other debris, which makes the water flow into the propeller blocked, affecting normal driving, and it needs to be cleaned manually regularly, which is very inconvenient.

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.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] According to the attached Figure 1-4 As shown, an embodiment of the utility model provides an unmanned boat for hydrological monitoring, comprising a hull 1, and a hydrological monitoring module 2 fixedly mounted on the upper surface of the hull 1, wherein the hull 1 is made of plastic, and a propulsion mechanism 3 is disposed at the tail of the hull 1;
[0031] The propulsion mechanism 3 includes an installation cavity 301 opened inside the hull 1, and a water pump 302 fixedly mounted on the bottom wall of the installation cavity 301. The installation cavity 301 is rectangular in shape. The liquid inlet end of the water pump 302 extends to the lower surface of the hull 1 and is fixedly provided with a filter cover for intercepting debris in the water. When the water pump 302 is turned off, the intercepted debris can automatically fall under the action of water buoyancy and gravity.
[0032] A T-shaped water pipe 303 is provided at the liquid outlet of the water pump 302. Both ends of the T-shaped water pipe 303 away from the water pump 302 extend to the outer surface of the hull 1 and are fixed with a propulsion pipe 304 connected to the T-shaped water pipe 303. The inner wall of the installation cavity 301 is provided with a sealed through hole for the T-shaped water pipe 303 to pass through.
[0033] The outer surface of the T-shaped water pipe 303 is provided with two symmetrical electromagnetic valves 305 for blocking the propulsion pipe 304. The setting of the electromagnetic valve 305 can realize the switching of water spraying of the two propulsion pipes 304, thereby realizing single-sided water spraying and achieving the purpose of steering.
[0034] Among them, the utility model sets a propulsion mechanism 3, so that when the unmanned boat for hydrological monitoring is traveling in the water area, water can be input into the interior of the T-shaped water pipe 303 through the water pump 302, and discharged through two propulsion pipes 304, providing power for the hull 1 to move forward, and when turning is required, an electromagnetic valve 305 can be opened and another electromagnetic valve 305 can be closed, so that one propulsion pipe 304 sprays water outward, thereby realizing the turning of the hull 1. Compared with the prior art, it abandons the original propeller propulsion, thereby effectively preventing the influence of debris in the surface water on the driving.
[0035] Both side surfaces of the hull 1 are provided with balancing components 4 for keeping the hull 1 balanced in windy and choppy weather. The balancing components 4 include two symmetrical mounting columns 401 fixed on the sides of the hull 1, and floating plates 402 fixed on the ends of the two mounting columns 401, wherein the material of the floating plates 402 is foam.
[0036] A cavity is formed inside the floating plate 402 , and the cavity is filled with a conductive liquid 403 , wherein the conductive liquid 403 is a sodium chloride solution.
[0037] A first conductive metal block 404 is embedded in the inner bottom wall of the cavity, and a second conductive metal block 405 is embedded in the top of the inner top wall of the cavity, wherein the materials of the first conductive metal block 404 and the second conductive metal block 405 are both copper;
[0038] The liquid level of the conductive liquid 403 is located in the middle of the cavity when the floating plate 402 is horizontal, that is, when the hull 1 is horizontal, the conductive liquid 403 does not contact the second conductive metal block 405 .
[0039] The balancing assembly 4 also includes an installation box 406 fixedly mounted on the outer surface of the hull 1 , and a high-pressure air pump 407 fixedly mounted on the inner bottom wall of the installation box 406 . The installation cavity 406 is used to effectively protect the high-pressure air pump 407 .
[0040] The air inlet end of the high-pressure air pump 407 extends to the upper surface of the installation box 406 and is fixedly provided with a rain cover to prevent rainwater from entering the interior of the high-pressure air pump 407. The air outlet end of the high-pressure air pump 407 extends to the lower surface of the installation box 406 and is fixedly provided with a T-shaped air pipe 408.
[0041] Both ends of the T-shaped air pipe 408 away from the high-pressure air pump 407 are blocked structures, and a plurality of air nozzles 409 are equidistantly embedded on the lower surface of the T-shaped air pipe 408 . The air nozzles 409 are air jet pipes pointing vertically downward.
[0042] The first conductive metal block 404 and the second conductive metal block 405 are both electrically connected to the high-pressure air pump 407 through a wire, that is, the first conductive metal block 404, the second conductive metal block 405 and the conductive liquid 403 are equivalent to a switch for starting the high-pressure air pump 407. When the conductive liquid 403 soaks the first conductive metal block 404 and the second conductive metal block 405, the first conductive metal block 404, the second conductive metal block 405 and the conductive liquid 403 are electrically connected, which is equivalent to turning on the switch and automatically starting the high-pressure air pump 407. On the contrary, when the conductive liquid 403 only soaks the first conductive metal block 404, a complete circuit is not formed at this time, that is, the switch is turned off, and the high-pressure air pump 407 is turned off.
[0043] Among them, the utility model provides a balancing component 4, so that when the unmanned boat is operating in rainwater with big waves, the stability of the unmanned boat during operation can be effectively improved under the action of the two floating plates 402. Moreover, when the hull 1 is overturned under the action of waves and wind, when the hull 1 is tilted and is about to flip over, that is, when a floating plate 402 is separated from the water surface and moves upward, the conductive liquid 403 in the cavity of the floating plate 402 in contact with the water area will tilt, so that the conductive liquid 403 electrically connects the first conductive metal block 404 and the second conductive metal block 405. At this time, it is equivalent to a switch being triggered, thereby automatically controlling the high-pressure air pump 407 to start, so that air is ejected through the air nozzle 409 at the bottom of the T-shaped air pipe 408, so that the hull 1 in contact with the water surface generates an upward thrust, which effectively blocks the tendency of the hull 1 to flip over, thereby effectively avoiding the hull 1 from capsizing due to the influence of big waves.
[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
