Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection, and particularly relates to a floating water quality monitoring station. Background Art

[0002] Water environment monitoring is a crucial tool for ensuring water resource quality, preventing water pollution, and protecting aquatic ecological balance. With the rapid development of industrialization and urbanization, the water environment faces increasingly severe challenges. Traditional water environment monitoring methods have many limitations, such as discontinuous data collection, limited monitoring range, and high costs. Therefore, the development of new water environment monitoring technologies is of great significance. Existing micro water quality monitoring stations are mostly cabinet-type, with problems such as poor water collection and drainage and high energy consumption. Especially when powered by solar energy, the high energy consumption of equipment such as water pumps significantly impacts battery life.

[0003] Patent document CN218298217U discloses a floating automatic water quality monitoring station. This station's obstacle-clearing mechanism allows for proper cleaning of floating aquatic plants around the station, facilitating its movement and multi-directional sampling. During use, a servo motor drives a fixed ring to rotate, causing two paddles to swing back and forth, clearing the surrounding aquatic plants and facilitating mobile monitoring of the water quality monitoring station. In implementing this technical solution, the inventors discovered that the prior art has at least the following problems:

[0004] When the above device is actually used, the debris around the float can be cleaned by swinging the paddle back and forth to avoid affecting the movement of the float, but it can only clean the debris on the water surface. Since the sampling tube is in the water, there is still the problem that the sampling tube is easily blocked by debris in the water, affecting the sampling of water quality, and the use effect is poor.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] like Figures 1-4 As shown, a floating water quality monitoring station includes a sampling tube 1, a filter tube 2 is fixedly installed on the bottom of the sampling tube 1, a cleaning component 3 is provided inside the filter tube 2, a plurality of filter holes 4 are opened inside the filter tube 2, a float 5 is fixedly installed on the top of the sampling tube 1, water inlets 6 are opened on both sides of the sampling tube 1, a water outlet 7 is opened at the bottom of the sampling tube 1, a solar panel 8 is bolted to the top of the float 5, and the inner walls of the water inlet 6 and the water outlet 7 are provided with screens.

[0023] The float 5 floats on the water surface to be tested, supporting the sampling tube 1. The water source enters through the water inlets 6 on both sides of the sampling tube 1 and flows into the filter tube 2 to sample the water quality. The water source is filtered through the screen built into the water inlet 6, the filter hole 4 inside the filter tube 2 and the screen built into the water outlet 7 to prevent debris from entering the filter tube 2 and affecting the water quality detection data. When maintenance is required, the sampling tube 1 is taken out of the water and the water source in the sampling tube 1 is discharged through the water outlet 7 for easy maintenance. The debris attached to the inner and outer walls of the filter tube 2 can be cleaned through the cleaning component 3 to improve the accuracy of the next detection.

[0024] It should be noted that the float 5 has a built-in battery, and the solar panel 8 is electrically connected to the charging end of the battery. The connections involved will not be described in detail here.

[0025] like Figure 2 and Figure 3As shown, the cleaning assembly 3 includes a rotating rod 31 rotatably arranged inside the sampling tube 1, a fixed rod 32 is fixedly connected to the bottom of the rotating rod 31, fixed seats 33 are fixedly connected on both sides of the fixed rod 32, scrapers 34 are provided on both sides of the bottom of the fixed seat 33, a rotating shaft 35 is fixedly connected to the center position of the bottom of the fixed rod 32, a reinforcing plate 36 is fixedly connected to the outside of the rotating shaft 35, a rotating plate 37 is fixedly connected to the bottom of the rotating shaft 35, a fixed tube 38 is fixedly connected to both sides of the top of the rotating plate 37, and a rotating frame 39 is rotatably connected to the inner wall of the fixed tube 38.

[0026] The fixing rod 32 is driven to rotate by the rotating rod 31, and the fixing rod 32 drives the fixing seat 33 at its bottom to rotate, so that the scrapers 34 on both sides of the bottom of the fixing seat 33 are adapted to rotate along the inner and outer walls of the filter cylinder 2 to clean the inner and outer walls of the filter cylinder 2 and the filter holes 4. The reinforcing plate 36 supports and reinforces the two scrapers 34 on the inner side of the filter cylinder 2 to improve the stability of the scraper 34 during rotation. When the fixing rod 32 rotates, the rotating shaft 35 is synchronously driven to rotate, and the rotating shaft 35 drives the rotating plate 37 to rotate. The rotating plate 37 drives the fixed cylinder 38 and the rotating frame 39 on both sides of its top to rotate. The rotating frame 39 is located at the water inlet 6, so that the garbage and debris at the water inlet 6 can be cleaned.

[0027] like Figure 3 As shown, a cleaning brush is provided on one side of the scraper 34, and one side of the cleaning brush is in contact with the filter cartridge 2. The cleaning brush improves the cleaning effect of the scraper 34 on the inner and outer walls of the filter cartridge 2. An ammonia nitrogen sensor and a full spectrum sensor are provided on the top of the reinforcement plate 36 respectively.

[0028] It should be noted that: this device uses a solar panel 8 as the main power source and is equipped with a lithium battery module to store electrical energy to ensure stable operation of the device without an external power supply. The ammonia nitrogen sensor in the filter cartridge 2 is mainly used to measure the ammonia nitrogen content in the water, and full-spectrum sensors such as the AMT / QGP-400 full-spectrum water quality sensor can quickly and in real time measure multiple parameters of the water body, providing a variety of options for water quality monitoring.

[0029] like Figure 2 and Figure 4 As shown, a motor 9 is provided inside the float 5, and a connecting rod 10 is fixedly connected to the output end of the motor 9. The connecting rod 10 is driven to rotate by the motor 9, and the connecting rod 10 is connected to the rotating rod 31, thereby driving the rotating rod 31 to rotate.

[0030] like Figure 4 As shown, a plurality of blocks 11 are fixedly connected to the outside of the connecting rod 10, and a slot 12 for use with the connecting rod 10 and the block 11 is opened inside the rotating rod 31. The connecting rod 10 is inserted into the slot 12 inside the rotating rod 31 through the four blocks 11 on the outside, so that the connecting rod 10 and the rotating rod 31 are interference-connected, thereby facilitating installation and disassembly and facilitating later maintenance.

[0031] like Figure 2 As shown, four fixing bolts 13 are provided on the top of the sampling tube 1. The outer side of the fixing bolts 13 is threadedly connected to the inner wall of the float 5. The sampling tube 1 is fixed to the float 5 by the fixing bolts 13, thereby facilitating the installation and disassembly of the sampling tube 1 and subsequent maintenance or repair work.

[0032] The working principle of the present invention is as follows: the float 5 floats on the water surface to be tested, supporting the sampling tube 1, and the water source enters through the water inlet 6 on both sides of the sampling tube 1 and flows into the inside of the filter tube 2 to sample the water quality. The water source is filtered through the screen built into the water inlet 6, the filter hole 4 inside the filter tube 2 and the screen built into the water outlet 7 to prevent debris from entering the filter tube 2 and affecting the water quality detection data. Finally, the water quality is detected through the sensor assembly in the filter tube 2. The scraper 34 is rotated to fit the inner and outer walls of the filter tube 2 to clean the inner and outer walls of the filter tube 2 and the filter hole 4. The rotating plate 37 drives the fixed tube 38 and the rotating frame 39 on both sides of its top to rotate. The rotating frame 39 is located at the water inlet 6, so that the garbage and debris at the water inlet 6 can be cleaned, thereby improving the accuracy of the detection.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
