[0002] A hydrometer is an instrument or device used to measure, monitor and record hydrological data. It is mainly used to measure various parameters of surface water or groundwater to help understand the characteristics, changes and dynamics of water bodies.

[0003] Chinese patent: CN202321597531.4 discloses a sinking hydrometer. To solve the problem that the detectors in the prior art cannot sink to different positions of the water body for detection, resulting in low survey efficiency, the electromagnetic valve is opened to allow water to enter the water tank, so that the weight of the entire device is increased and the device further sinks into the water body, thereby realizing the collection of hydrological information at different water depths;

[0004] However, in actual use of the hydrometer in the above-mentioned prior art, although the hydrometer uses water to enter the water tank to adjust the weight of the equipment to achieve rising and falling in the water, the density of water will change due to the different depths of the water area. When the water tank is filled with water, the hydrometer will float in the water body and cannot sink into deeper waters to collect hydrological data, which leads to certain limitations of the equipment.

[0005] Therefore, it is necessary to provide a submerged hydrological instrument to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] like Figures 1 to 5 As shown, the present application provides a submerged hydrometer, comprising a detection box 1, a hydrological sensor group 2, a connecting pipe 3 and a lifting assembly 5, wherein the lifting assembly 5 is used to drive the detection box 1 to descend and ascend in water, and a base 4 is provided at the lower end of the connecting pipe 3;

[0034] like Figures 1 to 5As shown, the lifting assembly 5 includes a counterweight block 57 connected to the lower end of the base 4 and a storage box 51 fixedly arranged on the top of the detection box 1, an air bag 56 is arranged on the top of the storage box 51, and a partition plate 52 is arranged inside the storage box 51. The partition plate 52 is conical and has a hollow bottom. The conical partition plate 52 facilitates the liquid at its upper end to flow to the hollow bottom thereof. The partition plate 52 divides the interior of the storage box 51 into a first accommodating chamber 511 and a second accommodating chamber 512. The first accommodating chamber 511 is used for placing hydrogen peroxide, and the second accommodating chamber 512 is used for placing manganese dioxide. A drain pipe 53 is connected to the bottom of the partition plate 52, and an electromagnetic valve 54 is installed on the drain pipe 53. The interior of the second accommodating chamber 512 is connected to an air injection pipe 55, one end of which is connected to the air bag 56, and a one-way valve 551 is arranged inside the air injection pipe 55. The one-way valve 551 is used to prevent the gas inside the air bag 56 from flowing back into the storage box 51.

[0035] In this embodiment, in the initial state, the airbag 56 is in a contracted state. By placing the entire device in water, the device can gradually sink to the bottom of the water under the weight of the counterweight 57. Then, the water body in the underwater area is collected through the hydrological sensor group 2, and the information is sent out through the main control unit and the wireless transmission unit inside the detection box 1 to realize the survey and collection of hydrological information. When it is necessary to control the detection box 1 and the hydrological sensor group 2 to rise in the water, the electromagnetic valve 54 is controlled to open, so that the hydrogen peroxide in the first accommodating chamber 511 flows into the second accommodating chamber 512 along the drain pipe 53, and the hydrogen peroxide is generated when it contacts with manganese dioxide. The chemical reaction can quickly generate a large amount of oxygen. The oxygen is input into the airbag 56 through the air injection pipe 55, so that the airbag 56 expands. The airbag will occupy a larger space. The expansion of the airbag 56 generates an upward buoyancy, which can drive the device as a whole to gradually rise. In the process of gradually rising, the detection box 1 and the hydrological sensor group 2 are used to detect waters of different depths, so as to achieve the effect of detecting waters of different depths. Compared with the existing technology, it has a wider range of applications when used. At the same time, the oxygen generated by manganese dioxide and hydrogen peroxide is non-toxic and harmless, and manganese dioxide can be recycled as a catalyst, further reducing resource waste;

[0036] It should be noted that the detection box 1 and the hydrological sensor group 2 in the present application as well as the main control unit and the transmission unit inside the detection box 1 are prior art. For details, please refer to the patent with application number CN202321597531.4, and no further details will be given here.

[0037] like Figure 4As shown, an injection tube 515 is provided on the top of the storage box 51, and the injection tube 515 is connected to the first accommodating chamber 511. The injection tube 515 is used to easily inject hydrogen peroxide into the first accommodating chamber 511. A first sealing cover 516 is threadedly connected to the top of the injection tube 515, and the injection tube 515 is sealed by the first sealing cover 516.

[0038] like Figure 4 As shown, a material injection port 513 is provided on one side of the material storage box 51, and the material injection port 513 corresponds to the second accommodating chamber 512. The material injection port 513 facilitates the addition of manganese dioxide into the second accommodating chamber 512. A sealing plate 514 is provided on the outer side of the material injection port 513, and the sealing plate 514 is connected to the material storage box 51 by bolts.

[0039] like Figure 3 and Figure 5 As shown, a connecting column 41 is provided at the bottom of the base 4, and a connecting hole 571 is opened at the top of the counterweight block 57. The connecting column 41 is threadedly connected to the connecting hole 571. Counterweight blocks 57 of different weights can be selected for use according to different depths of water. The counterweight block 57 is conveniently installed on the base 4 through the threaded connection between the connecting column 41 and the connecting hole 571.

[0040] like Figure 4 As shown, the airbag 56 is provided with an exhaust pipe 561 , which is used to discharge the gas inside the airbag 56 , and a second sealing cover 562 is threadedly connected to the exhaust pipe 561 .

[0041] In this embodiment, when the equipment has completed the detection of the water area, the buoyancy of the airbag 56 makes the equipment float on the water surface as a whole. After the staff retrieves the equipment, they screw the second sealing cover 562 to separate it from the exhaust pipe 561, and the gas inside the airbag 56 can be discharged from the exhaust pipe 561. Then the second sealing cover 562 is tightened onto the exhaust pipe 561 again. At the same time, the first sealing cover 516 can be screwed to separate it from the injection pipe 515, and hydrogen peroxide can be injected into the first accommodating chamber 511 through the injection pipe 515. Then the first sealing cover 516 is tightened onto the injection pipe 515 again, and then the bolts located on the outside of the sealing plate 514 are screwed, and the sealing plate 514 is removed, and manganese dioxide is added to the second accommodating chamber 512 through the injection port 513. Then the sealing plate 514 is reinstalled, and the next water area can be detected.
