[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, it is sometimes necessary to measure the flow rate and flow. Water quality monitoring will use water quality monitoring devices for real-time online monitoring.

If the float is not positioned, the water quality monitoring device will float on the water surface, resulting in the water quality monitoring device being unable to accurately monitor an area, thereby reducing the practicality of the water quality monitoring device.

Therefore, by setting an embedding mechanism, after the counterweight block sinks into the mud and sand at the bottom of the water, the hydraulic rod is started to drive the first push block and the first piston to move downward, compressing the gas in the pneumatic groove. Under the influence of the air pressure, the second piston and the second push block will move to the side close to the spring, and at the same time, the second push block will drive the embedding rod to be laterally embedded in the mud and sand, further improving the grip and stability of the counterweight block;

At this time, the winding rope wrapped on the winding wheel will slowly descend with the counterweight until the counterweight enters the mud on the bottom of the water. Under the influence of the gravity of the counterweight, the float and the monitoring instrument body will not float and move. At the same time, the embedded mechanism can improve the grip and stability of the counterweight, thereby solving the problem in the background technology that if the float is not positioned, it will drive the water quality monitoring device to float on the water surface, resulting in the water quality monitoring device being unable to accurately monitor an area, thereby reducing the practicality of the water quality monitoring device.

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A mobile online water quality monitoring device comprises a float 1, a monitor body 2, a solar cell 3 and an alarm light 4. The monitor body 2 and the alarm light 4 are both fixedly mounted on the top of the float 1, the solar cell 3 is fixedly mounted on the top of the monitor body 2, and a sensor 5 is fixedly mounted on the bottom of the float 1;

[0031] Counterweight mechanisms are provided on both sides of the sensor 5, which can prevent the water quality monitoring device from floating on the water surface.

[0032] One implementation of this embodiment is as follows: the counterweight mechanism includes two storage boxes 6 fixedly connected to the bottom of the float 1, a waterproof motor 7 is fixedly installed on one side of the storage box 6, the output end of the waterproof motor 7 passes through the interior of the storage box 6, and is fixedly connected to a winding wheel 8, a winding rope 9 is fixedly connected to the surface of the winding wheel 8, and a counterweight block 10 is fixedly connected to the bottom of the winding rope 9;

[0033] In this embodiment, it is considered that if the float 1 is not positioned, it will drive the water quality monitoring device to float on the water surface, resulting in the inability of the water quality monitoring device to accurately monitor an area, thereby reducing the practicality of the water quality monitoring device. Therefore, by setting a counterweight mechanism, after the float 1 is moved to an appropriate position, the waterproof motor 7 is started to rotate, driving the winding wheel 8 to rotate. At this time, the winding rope 9 wound on the winding wheel 8 will slowly descend with the counterweight block 10 until the counterweight block 10 enters the bottom mud. Under the influence of the gravity of the counterweight block 10, the float 1 and the monitoring instrument body 2 will not float and move;

[0034] The problem that if the float 1 is not positioned, the water quality monitoring device will float on the water surface, causing the water quality monitoring device to be unable to accurately monitor an area, thereby reducing the practicality of the water quality monitoring device is solved;

[0035] It should be noted that when the water quality monitoring device needs to be moved, the waterproof motor 7 is reversed to store the winding rope 9 and at the same time the counterweight 10 floats up.

[0036] Preferably, the counterweight 10 is conical;

[0037] In this embodiment, it is considered that the gravity effect will be better when the counterweight block 10 enters the bottom mud, so by setting the counterweight block 10, the counterweight block 10 can be designed to be conical, so that the counterweight block 10 will be more easily embedded in the mud during the falling process.

[0038] Preferably, a bearing seat 20 is provided on one side of the winding wheel 8, and the bearing seat 20 is rotatably connected to the storage box 6;

[0039] In this embodiment, the smoothness of the winding wheel 8 during rotation is taken into consideration. Therefore, by providing a bearing seat 20, the winding wheel 8 can be restricted to rotate only, playing a supporting role, and at the same time improving the smoothness of the winding wheel 8 during rotation.

[0040] Embodiment 2:

[0041] On the basis of the first embodiment, the counterweight mechanism in this embodiment can make the float 1 and the monitoring instrument body 2 not float and move by the gravity of the counterweight block 10 entering the water. However, considering that if there is a strong wind on the water surface, the counterweight block 10 may be difficult to ensure the stability of the float 1, the counterweight block 10 in this application is provided with an embedding mechanism inside, which can improve the stability of the water quality monitoring device by embedding the counterweight block 10 into the mud and sand in the water;

[0042] The embedding mechanism includes a pneumatic groove 11 provided inside the counterweight 10, a hydraulic rod 12 is fixedly installed on the inner wall of the pneumatic groove 11, a first push block 13 is fixedly connected to the output end of the hydraulic rod 12, two movable grooves 14 are provided on the inner wall of the pneumatic groove 11, a second push block 15 is movably connected to the inner wall of the movable groove 14, an embedding rod 16 is fixedly connected to one side of the second push block 15, and one end of the embedding rod 16 penetrates the outer side of the counterweight 10;

[0043] In this embodiment, it is considered that if there is a strong wind on the water surface, the counterweight 10 may be difficult to ensure the stability of the float 1. Therefore, by setting an embedding mechanism, after the counterweight 10 sinks into the mud and sand at the bottom of the water, the hydraulic rod 12 is started to drive the first push block 13 and the first piston 18 to move downward, and the gas in the pneumatic groove 11 is compressed. Under the influence of the air pressure, the second piston 19 and the second push block 15 will move to the side close to the spring 17, and at the same time, the second push block 15 will drive the embedding rod 16 to be laterally embedded in the mud and sand, so as to further improve the grip and stability of the counterweight 10;

[0044] The problem that the counterweight 10 may be difficult to ensure the stability of the float 1 in the event of strong wind on the water surface is solved;

[0045] It should be noted that when the hydraulic rod 12 is reset, the air pressure in the pneumatic groove 11 is restored, and the second push block 15 and the embedded rod 16 are reset under the influence of the reaction force of the spring 17 .

[0046] Preferably, a spring 17 is sleeved on the surface of the embedded rod 16, one end of the spring 17 is fixedly connected to one side of the second push block 15, and the other end of the spring 17 is fixedly connected to the inner wall of the moving groove 14;

[0047] In this embodiment, it is considered that the subsequent embedded rod 16 is difficult to reset. Therefore, a spring 17 is provided so that after the air pressure in the pneumatic groove 11 is restored, the second push block 15 and the embedded rod 16 can be reset under the influence of the reaction force of the spring 17.

[0048] Preferably, a first piston 18 is fixedly connected to the bottom of the first pushing block 13, and a second piston 19 is fixedly connected to one side of the second pushing block 15;

[0049] In this embodiment, considering that the power source driven by the embedded mechanism is air pressure, it is necessary to ensure that the pneumatic groove 11 and the movable groove 14 are a closed chamber. Therefore, by setting the first piston 18 and the second piston 19, the sealing of the first push block 13 and the second push block 15 can be improved, thereby ensuring that the pneumatic groove 11 and the movable groove 14 are a closed chamber.

[0050] Working principle: After the user moves the float 1 to an appropriate position, the user starts the waterproof motor 7 to rotate, driving the reel 8 to rotate. At this time, the reel rope 9 wound on the reel 8 will slowly descend with the counterweight 10 until the counterweight 10 enters the bottom mud. Under the influence of the gravity of the counterweight 10, the float 1 and the monitor body 2 will not float and move;

[0051] After the counterweight 10 sinks into the mud and sand at the bottom of the water, the hydraulic rod 12 is started to drive the first push block 13 and the first piston 18 to move downward, compressing the gas in the pneumatic groove 11. Under the influence of the air pressure, the second piston 19 and the second push block 15 will move to the side close to the spring 17. At the same time, the second push block 15 will drive the embedding rod 16 to be laterally embedded in the mud and sand, further improving the grip and stability of the counterweight 10.

[0052] It should be noted that the waterproof motor 7 and the hydraulic rod 12 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the waterproof motor 7 and the hydraulic rod 12 are clear to those skilled in the art, so they will not be described in detail.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
