TECHNICAL FIELD

[0001] The utility model relates to water quality monitoring technical field, concretely relates to a buoy type water quality monitoring device. BACKGROUND

[0002] The buoy type water quality monitoring device is widely used in rivers, lakes and oceans and other water bodies, and can monitor water quality for a long time and continuously. This kind of device usually installs sensors on the buoy, floats on the water surface, and monitors water quality indexes such as temperature, pH value, dissolved oxygen, etc.

[0003] The existing buoy type water quality monitoring device often has large fluctuations in monitoring data under the condition of large water surface fluctuation due to the action of waves, and even cannot effectively obtain the real water quality information. This is because the turbulence of water flow and waves will interfere with the work of the sensor, causing the sensor to be unable to stably detect the water quality below the water body. In addition, the sundries or floating objects on the water surface may also cause physical obstruction to the sensor, further reducing the monitoring accuracy. Based on this, we propose a buoy type water quality monitoring device. SUMMARY

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0025] The embodiment provides a float type water quality monitoring device, which comprises a float body, a frame, an electric control box, a water quality sensor, a horizontal plate, a float and a spring. Figures 1 to 5As shown, including the buoy body 1, the upper end of the buoy body 1 is provided with a rack 2, the inside of the rack 2 is provided with an electric control box 3, the outer side of the rack 2 is provided with a photovoltaic panel, the outer side of the photovoltaic panel is provided with a protective rail, the protective rail is fixedly installed on the buoy body 1, the photovoltaic panel converts solar energy into electric energy, the electric energy is stored in the electric control box 3 and provides power supply for each electric equipment, the lower part of the buoy body 1 is provided with a water quality sensor 4, the water quality sensor 4 and the photovoltaic panel are electrically connected with the electric control box 3, the water quality sensor 4 detects the water quality of the target water area and transmits the detection result to the electric control box 3, the electric control box 3 transmits the detection result to the local server, but in actual application, since the water surface fluctuation is common in natural water body, especially when the wind wave or ship passes, the buoy on the water surface will be disturbed by the wave, the water flow turbulence and the wave will disturb the work of the water quality sensor 4, the reading of the water quality sensor 4 is unstable, and the monitoring accuracy is affected, therefore, we slide the water quality sensor 4 along the vertical direction and assemble it on the buoy body 1, when the water surface fluctuates, the water quality sensor 4 is moved downward to the relatively stable underwater area, the disturbance of the water surface turbulence and the wave is avoided, and the stability and accuracy of the monitoring data are improved.

[0026] On the basis of the above scheme, we utilize the wave action generated by water surface fluctuation to drive the water quality sensor 4 to move in the vertical direction, specifically, the lower end surface of the buoy body 1 is integrally formed with a transverse plate 5 distributed along the radial direction thereof, a horizontal guide groove 51 is formed in the inside of the transverse plate 5 along the length direction thereof, and two symmetrically arranged floaters 6 are slidingly assembled in the horizontal guide groove 51, in the present embodiment, the floaters 6 are in hollow cylindrical structure, a guide plate 53 is installed between the two floaters 6, and the guide plate 53 is slidingly assembled in the horizontal guide groove 51; the two floaters 6 are alternately fluctuated under the action of the wave, and drive the guide plate 53 to perform linear reciprocating motion in the horizontal guide groove 51, a guide groove 54 is formed in the middle part of the guide plate 53, the guide groove 54 is in inverted V-shaped structure, a vertical guide groove 41 is formed in the inside of the transverse plate 5 along the vertical direction, a vertical sliding block 42 is slidingly assembled in the vertical guide groove 41, the lower end of the vertical sliding block 42 is fixedly connected with the upper end of the water quality sensor 4, a guide rod 43 is installed on the end surface of the vertical sliding block 42 close to the guide plate 53, and the guide rod 43 is slidingly assembled in the guide groove 54; when the water surface is calm, the guide rod 43 is located at the middle position of the guide groove 54, at this time, the guide rod 43 is at the highest point in the guide groove 54, and the distance between the terminal end of the water quality sensor 4 and the water surface is the shortest; when the water surface appears wave, the periodic sinusoidal motion law of the wave can realize the alternately lifting of the floaters 6, when the floater 6 on one side is lifted, the floater 6 on the other side will be lowered, so that the whole transverse plate 5 is obliquely arranged, at this time, the guide rod 43 moves from the middle of the guide groove 54 to one side, that is, from the highest point to the lowest point, in this process, the vertical sliding block 42 moves along the vertical guide groove 41 towards the water, the distance between the water quality sensor 4 and the water surface is increased, and the terminal end of the water quality sensor 4 moves to the relatively stable underwater area, avoiding the interference of the water flow turbulence and the wave to the sensor, and improving the stability and accuracy of the monitoring data.

[0027] When the water surface is in a calm state, the guide rod 43 is preferably located at the middle position of the guide groove 54, so as to facilitate the conversion of the horizontal linear motion of the guide plate 53 into the vertical linear motion of the water quality sensor 4, for this purpose, we install a horizontal sliding block 52 on both ends of the guide plate 53, the horizontal sliding block 52 is slidingly assembled in the horizontal guide groove 51, and a spring 55 is installed between the horizontal sliding block 52 and the end of the horizontal guide groove 51; when the transverse plate 5 is in an inclined state, the spring 55 on one side is compressed to exert a pushing force on the horizontal sliding block 52, and the spring 55 on the other side is stretched to exert a pulling force on the horizontal sliding block 52; when the water surface is in a static state, the horizontal sliding block 52 is pushed to the middle position of the horizontal guide groove 51 by the resultant force of the two springs 55, at this time, the guide rod 43 is just located at the middle position of the guide groove 54.

[0028] In addition, when the float 6 moves along the transverse guide groove 51 towards the direction close to the buoy body 1, the horizontal plate 5 inclines towards the direction close to the other float 6, at this time, the float 6 is in the lifting state, the contact volume with the water body is reduced, the buoyancy provided is reduced, the other float 6 is in the lowering state, and the contact volume with the water body is increased, the buoyancy provided is increased, and the asymmetric buoyancy on both sides makes the buoy body 1 move from the inclined state to the horizontal state, thereby reducing the probability of the buoy body 1 being overturned.

[0029] On the basis of the above scheme, when the horizontal plate 5 is in the inclined state, both of the floats 6 move towards the inclined direction, so that the gravity center of the whole device is deviated to one side, and the probability of the device being overturned is increased. Therefore, the float 6 is designed to be movable in the vertical direction, when the horizontal plate 5 is in the inclined state, the float 6 in the lifting state moves away from the water body, the buoyancy is reduced, and the float 6 in the lowering state moves towards the water body, the buoyancy is increased, so that the difference of the buoyancy on both sides is increased, and the gravity center deviation is compensated. Specifically, the vertical rod 63 is connected in the vertical direction through the vertical sliding block 52, the lower end of the vertical rod 63 is connected with the float 6, and the upper end of the vertical rod 63 is provided with the slide rod 62. The horizontal plate 5 is provided with the inclined groove 61 which is inclined towards the upper inner side at the position corresponding to the slide rod 62, and the slide rod 62 is slidably arranged in the inclined groove 61. When the water surface is in the calm state, the slide rod 62 is located in the middle of the inclined groove 61. When the horizontal plate 5 is in the inclined state, the slide rod 62 in the lifting state moves inwards from the middle of the inclined groove 61, so that the float 6 connected with the slide rod 62 moves upwards, and the contact volume with the water body is reduced. In the same way, the slide rod 62 in the lowering state moves outwards from the middle, so that the float 6 connected with the slide rod 62 moves downwards, and the contact volume with the water body is increased.
