[0002] The floating type on-line water quality monitoring equipment is a device for real-time monitoring of water quality parameters, mainly composed of a water quality sensor, a data collector, a communication system, a power supply system, etc., and can monitor a variety of water quality parameters, including water temperature, pH value, conductivity, dissolved oxygen, ammonia nitrogen, turbidity, etc. These data are transmitted to the cloud platform in real time through the data collector, and users can remotely access the monitoring data through terminal devices such as computers and mobile phones to understand the water quality status in real time. The device is applicable to multiple fields such as industrial and agricultural production, tourism, urban environmental monitoring, geological disasters, flood control, water supply scheduling, etc., and is widely used in some relatively broad waters, especially in some lakes or oceans. However, when the current on-line water quality monitoring equipment is in use, its functions are relatively single, and it can only collect water quality parameters and transmit them remotely. When in use, it is not convenient to collect samples at each time point and data in different water layers. Moreover, when used for a long time, a large amount of waterweeds or adherent organisms, such as barnacles, will adhere to the surface of the floating member, which not only affects the service life, but also affects the water quality in the water quality collection area during water quality parameter collection, thus affecting the accuracy of water quality monitoring.

When conducting water quality monitoring, through the floating plate and the floating ring, the present technical solution floats on the water body. When water quality monitoring is not carried out, the lifting column rises to the highest position, and the monitoring head is located in the space formed by the inner circle of the floating ring and the floating plate, not in contact with the water body, avoiding being damaged due to long-term immersion in the water body. When conducting monitoring, the driving component drives the lifting column, enabling the lifting column to vertically slide on the floating plate to adjust the position of the monitoring head, and by controlling the monitoring head to be located at different depths of the water body, it is convenient to monitor the water quality of different water layers. And during monitoring, through the sampling component, water samples at the monitoring position are sampled and the water body at the monitoring position is sealed, facilitating re-inspection later.

One side of the lifting column is slidably clamped on the slide rail, and a pull rod with a ring is fixedly installed in a circumferential array on the outer side of the through hole at the lower end of the floating plate.

Through the cameras, when the round table rises to a high position with the lifting column, the cameras collect images of the water surface to facilitate observing whether there are floating pollutants. Through the groove, it is convenient to store the sampling tube in the sampling assembly. During sampling, water enters the inside of the sampling tube through the water intake hole, facilitating sampling of the water body at the position of the monitoring head.

The winch and the water pump are both fixedly installed on the floating plate. The water pump is a suction and discharge dual-purpose water pump. During monitoring, when the lifting column moves up and down, the winch pays out or winds up the sampling tube to prevent the sampling tube from getting messy, making the sampling tube located inside the groove. And when sampling is required, the position of the lifting column is adjusted. After the adjustment is completed, the water pump pumps water, causing the water body to enter the sampling tube through the water intake hole and be sprayed out through the water outlet head. The sprayed water body is injected into the sample bottle for sealing.

[0011] Preferably, the sampling assembly further includes a fixed seat fixedly installed on one side of the water pump. The fixed seat is of a U-shaped structure.

A notch is provided in the middle position of the sealing frame, and the water outlet head is located on one side of the notch.

[0014] The beneficial effects of the present invention are as follows: 1. By adopting a double-headed motor, when driving, not only the position of the monitoring head in the water layer is adjusted, but also the scraper is driven, so that the scraper cleans the surface of the floating ring, reducing the attachment of waterweeds or organisms, with strong coordination and being convenient for long-term online monitoring.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] As Figures 1-13As shown in the figure, this embodiment provides a floating type on-line water quality monitoring device, which includes a floating component 1. The floating component 1 is composed of a floating plate 101 and a floating ring 102. The floating ring 102 is fixedly installed at the lower end of the floating plate 101. A monitoring component 2 is vertically slidably clamped at the middle position of the floating plate 101. The monitoring component 2 includes a lifting column 201 and a monitoring head 202. The monitoring head 202 adopts an integrated water quality sensor and is used to detect the water temperature, pH value, conductivity, dissolved oxygen, ammonia nitrogen and turbidity of the water body. The monitoring head 202 is fixedly installed at the lower end of the lifting column 201. A driving component 3 is fixedly installed on one side of the upper surface of the floating plate 101. The output ends of the driving component 3 are respectively engaged with the floating component 1 and the lifting column 201. A sampling component 4 is fixedly installed on the other side of the upper surface of the floating plate 101, and the water inlet end of the sampling component 4 is fixedly installed at the lower end of the lifting column 201. The upper surface of the floating plate 101 is fixedly installed with a light energy utilization component 5 in a circumferential array. The light energy utilization components 5 enclose a conical structure. Energy storage modules 6 and a control module 7 are respectively fixedly installed on the front and rear sides of the upper surface of the floating plate 101. Through the energy storage module 6, when the light energy utilization component 5 converts the external light energy into electric energy, it is stored, and through the energy storage module 6, power is supplied to the monitoring component 2, the driving component 3, the sampling component 4 and the control module 7, so as to improve the endurance during use. And through the control module 7, a control program is written in the control module 7 to achieve the effect of intelligent control of the monitoring component 2, the driving component 3 and the sampling component 4, and the water quality data monitored by the monitoring component 2 is wirelessly transmitted to an external terminal. When conducting water quality monitoring, through the floating plate 101 and the floating ring 102, this technical solution floats on the water body. The floating ring 102 is made of hollow hard plastic steel, which improves the corrosion resistance during use and is convenient for use in seawater, improving the applicability. And when water quality monitoring is not carried out, the lifting column 201 rises to the highest position, and the monitoring head 202 is located in the space formed by the inner circle of the floating ring 102 and the floating plate 101 and does not contact the water body, avoiding being damaged due to long-term immersion in the water body. When the lifting column 201 is at the highest position, only the lower side of the floating ring 102 and the counterweight 206 in the monitoring component 2 are located in the water body in this technical solution. And when conducting monitoring, the driving component 3 drives the lifting column 201, so that the lifting column 201 slides vertically on the floating plate 101, and then the position of the monitoring head 202 is adjusted. By controlling the monitoring head 202 to be located in water bodies at different depths, it is convenient to monitor the water quality of different water layers. And during the monitoring, through the sampling component 4, water samples at the monitoring position are taken, and the water body at the monitoring position is sealed, which is convenient for later re-inspection. And during each monitoring, the sampled water body is separately packaged to avoid sample mixing, improve the consistency between the sample and the water body at the monitoring position, and improve the monitoring accuracy.

[0033] As a technical optimization scheme of the present invention, specifically asFigure 4 and Figure 5 As shown in Figure 5 , a through hole 103 is provided at the middle position of the upper surface of the floating board 101, and a slide rail 104 is vertically and fixedly installed on one side of the through hole 103. One side of the lifting column 201 is slidably clamped on the slide rail 104, and a pull rod 105 with a ring is fixedly installed in a circumferential array on the outer side of the through hole 103 at the lower end of the floating board 101. When floating and placing on the water body, through an external rope, it is convenient to connect the anchor at the bottom of the water body to the ring on the pull rod 105, so as to prevent the technical solution from drifting with the water body. And through the through hole 103 and the slide rail 104, when the driving assembly 3 drives the monitoring assembly 2, it is convenient to lift the lifting column 201, adjust the position of the monitoring head 202, and monitor water layers at different depths, improving the applicability during use. A slip ring 106 is fixedly installed on the outer side of the upper surface of the floating board 101, and a gear ring 107 is slidably clamped on the slip ring 106. One end of the driving assembly 3 is engaged with the gear ring 107, and arc-shaped scraping plates 108 are fixedly installed in a circumferential array on the outer side of the gear ring 107. The inner side of the scraping plate 108 is in contact with the outer surface of the floating ring 102. Through the slip ring 106 and the gear ring 107, when the driving assembly 3 is started, one end of the driving assembly 3 drives the gear ring 107, so that the gear ring 107 rotates on the slip ring 106, and then the scraping plate 108 rotates with the gear ring 107 to scrape and clean the lower surface of the floating ring 102, preventing waterweeds or attached organisms from adsorbing on the floating ring 102 and avoiding sundries from affecting the water quality at the monitoring position. For example, when waterweeds grow on the floating ring 102, during monitoring, the dissolved oxygen content at the position of the floating ring 102 is higher than that at the position without waterweeds, resulting in distortion of the monitoring accuracy and affecting the use.

[0034] As a technical optimization scheme of the present invention, specifically as Figure 6 and Figure 7As shown in the figure, a slide bar 203 is vertically and fixedly installed on one side of the lifting column 201.

One end of the driving assembly 3 is engaged with the rack 204. A pull rope 205 is fixedly installed at the middle position of the lower end of the monitoring head 202, and a counterweight 206 is fixedly installed at the lower end of the pull rope 205. A frustum 207 is fixedly installed at the upper end of the lifting column 201, and a warning light 208 is fixedly installed on the upper surface of the frustum 207. Through the slide bar 203, it is convenient to guide the lifting column 201 during lifting, so that the lifting column 201 can be lifted and lowered along the slide rail 104 through the slide bar 203, and through the rack 204, when the driving assembly 3 is started, the lifting column 201 can be lifted and lowered inside the through hole 103. Through the pull rope 205 and the counterweight 206, the vertical effect of the lifting column 201 during use is improved, the monitoring effect of the monitoring head 202 on the water body is improved, and through the warning light 208, when it is placed in a vast water area, it is convenient to observe and find. Cameras 209 are fixedly installed on the outer side of the lower surface of the frustum 207 in a circumferential array, and a groove 2010 is opened on one side of the lifting column 201. The water inlet end of the sampling assembly 4 is fixedly installed inside the lower end of the groove 2010. A water intake hole 2011 is opened above the lower end of the lifting column 201 where the monitoring head 202 is located. The water intake hole 2011 is communicated with the water inlet end of the sampling assembly 4 inside the groove 2010. Through the cameras 209, when the frustum 207 rises to a high position along with the lifting column 201, the cameras 209 collect images of the water surface, which is convenient to observe whether there are floating pollutants and is convenient for image monitoring. And through the groove 2010, it is convenient to store the sampling tube 402 in the sampling assembly 4, and one end of the sampling tube 402 can be lifted and lowered along with the lifting column 201. During sampling, water enters the inside of the sampling tube 402 through the water intake hole 2011, which is convenient to sample the water body at the position of the monitoring head 202 and convenient for later re-inspection.

The driving component 3 further includes a speed change box 303. The output shaft at the other end of the double-headed motor 301 is fixedly connected to the input end of the speed change box 303. A second driving gear 304 is fixedly installed at the output end of the speed change box 303. The second driving gear 304 meshes with the gear ring 107. The double-headed motor 301 facilitates the driving of the first driving gear 302 and the speed change box 303. When the first driving gear 302 rotates, the first driving gear 302 drives the rack 204 on the lifting column 201, causing the lifting column 201 to move. By controlling the forward and reverse rotation directions of the double-headed motor 301, the lifting control of the lifting column 201 is facilitated. When the speed change box 303 is driven by the double-headed motor 301, the speed change box 303 drives the second driving gear 304, causing the gear ring 107 to rotate on the slip ring 106, facilitating the cleaning of the floating ring 102.
