Description

Technical Field

[0001] The present invention relates to the field of water pollution monitoring, and particularly to a water pollution monitoring instrument and a monitoring system. Background Art

[0002] Biomass combustion for energy supply is a technology that uses biomass resources as fuels and converts the chemical energy in biomass into heat energy or electrical energy through the combustion process. Biomass resources can be regenerated annually and have a large output, making them a sustainable energy source. Biomass fuels have low sulfur and nitrogen contents, and produce fewer pollutants such as sulfur oxides and nitrogen oxides during the combustion process. At the same time, the CO2 released during biomass combustion is roughly equivalent to the CO2 absorbed during its growth through photosynthesis. Therefore, the carbon emissions of biomass combustion for energy supply are relatively low, which helps to reduce the greenhouse effect. Biomass resources are widely distributed in nature, including agricultural and forestry wastes such as plant straws, corncobs, rice husks, sawdust, and the organic part of municipal solid waste. However, biomass combustion generates solid wastes such as particulate matter and ash residues, which may contain heavy metals and other harmful substances, easily causing water pollution and thus affecting the surrounding environment.

Detailed implementation manners

[0030] Example 1, as Figures 1-2 shown, a water pollution monitoring instrument proposed by the present invention includes a floating component 2 and a sinking component 3 connected by a tensile connecting piece 1; a control box 4 is arranged on the floating component 2 for processing water pollution data and setting water pollution monitoring parameters; a water absorption space is arranged outside the sinking component 3, and the self-weight is adjusted by controlling the water absorption amount of the water absorption space to achieve the purpose of sinking / floating. A sampling component is arranged inside the sinking component 3, and the pollution data of the water sample is obtained by the movement of the sampling container; a monitoring and connecting component 5 is arranged at the bottom of the sinking component 3. When moving downward, the monitoring end is exposed to monitor the water pollution environment, and at the same time, the connecting end separates the sampling container from the sampling component and makes it extend into the water for sampling; when moving upward, the monitoring end retracts for protection, and at the same time, the sampling container on the connecting end is reset and the water sample is detected.

[0031] As Figures 3-4As shown in the figure, the sinking component 3 includes an upper plate 308, a lower plate 309, and a telescopic sleeve 307 located between the upper plate 308 and the lower plate 309; an upper mounting ring 302 is located on the outer periphery of the upper plate 308; a lower mounting ring 303 is located on the outer periphery of the lower plate 309; a telescopic bladder 301 is located between the upper mounting ring 302 and the lower mounting ring 303 and is arranged around the telescopic sleeve 307. The inside of the telescopic bladder 301 is the water absorption space, and a two-way pressure valve 306 is arranged on the telescopic bladder 301; a pulling and releasing member 305 is located between the upper mounting ring 302 and the lower mounting ring 303. By pulling and releasing and stretching, the distance between the upper mounting ring 302 and the lower mounting ring 303 is adjusted, so that the telescopic bladder 301 is stretched and compressed synchronously, the inflow and outflow of water in the water absorption space are adjusted, and the purpose of adjusting the self-weight is achieved.

[0032] As Figure 5 shown in the figure, the pulling and releasing member 305 includes a mounting box 30501, an electric roller 30502 located inside the mounting box 30501, and a pulling and releasing steel cable 30503 that is wound around the electric roller 30502 and is respectively connected to the upper mounting ring 302 and the lower mounting ring 303.

[0033] When the electric roller 30502 rotates to lengthen the pulling and releasing steel cable 30503, the telescopic bladder 301 and the telescopic sleeve 307 are stretched synchronously, a negative pressure environment is formed in the water absorption space, and the two-way pressure valve 306 allows water to enter the water absorption space. The self-weight of the sinking component 3 increases and it can sink to the required water level. When the electric roller 30502 rotates to shorten the pulling and releasing steel cable 30503, the telescopic bladder 301 and the telescopic sleeve 307 are compressed synchronously, a high-pressure environment is formed in the water absorption space, and the two-way pressure valve 306 discharges water. The self-weight of the sinking component 3 decreases and it can float to the required water level.

[0034] As Figures 6-7 shown in the figure, the sampling component is located in the chamber formed by the upper plate 308, the lower plate 309, and the telescopic sleeve 307; the sampling component includes a conveying member 310 installed on the lower plate 309 and multiple groups of sampling members 311 installed on the conveying member 310; the conveying member 310 drives the sampling members 311 to move so that their communication ends are sequentially opposite to the communication component 5 of the monitoring, and sampling is carried out respectively.

[0035] As Figure 8 shown in the figure, the conveying member 310 includes two sets of telescopic frames 31001 with the top connected to the bottom of the upper plate 308 and the bottom connected to the lower plate 309; electric rollers 31003 are respectively arranged on the fixed sections of the two sets of telescopic frames 31001; the conveyor belt 31002 rotates above the monitoring communication component 5 by sleeving the electric rollers 31003 on both ends correspondingly.

[0036] It should be further noted that the telescopic frame 31001 has a double-layer structure. One layer is the fixed section, which is connected to the lower layer plate 309, and the other layer is the telescopic section, which is slidably connected to the fixed section and at the same time connected to the upper layer plate 308. As the telescopic bladder 301 expands and contracts, the chamber expands and contracts synchronously, and the telescopic frame 31001 always supports inside the chamber, making the height of the conveyor belt 31002 fixed.

[0037] It should be further noted that the conveyor belt 31002 is arranged in a double-layer structure, and multiple groups of sampling components 311 are arranged between the two groups of conveyor belts 31002 and move downwards and upwards along with the conveyor belt 31002. When moving upwards, the water sample can be detected, and when moving downwards, it can be opposite to the monitoring connection component 5.

[0038] As Figure 8 shown, the sampling component 311 is a sampling container, including a mounting seat 31106 located on the conveyor belt 31002; the fixed adsorption seat 31108 is driven by a cylinder 31107 to move up and down on the mounting seat 31106; the movable adsorption seat 31101 is detachably adsorbed to the fixed adsorption seat 31108; the top cover 31102 is arranged on the movable adsorption seat 31101, and a sample detection probe 31103 is arranged inside the cover; the bottle body 31104 is detachably connected to the cover opening of the top cover 31102, and a one-way pressure valve 31105 is arranged at the bottom.

[0039] It should be further noted that the fixed adsorption seat 31108 is an electromagnet, which generates magnetism when energized; a positioning groove with a metal layer is arranged on the movable adsorption seat 31101 and is engaged and adsorbed with the energized fixed adsorption seat 31108.

[0040] It should be further noted that the bottle body 31104 and the top cover 31102 are threadedly connected, and after the detection is completed, the bottle body 31104 is taken out for cleaning.

[0041] When sampling is required, the bottle body 31104 adsorbed on the fixed adsorption seat 31108 is moved to the monitoring connection component 5, and the bottle body 31104 is driven into the water by pressing down through the monitoring connection component 5. At the same time, the water pressure increases, and the water sample enters the bottle body 31104 from the one-way pressure valve 31105. Then the bottle body 31104 moves upwards along with the conveyor belt 31002, and the water sample and the particulate matter in the water sample can fall into the top cover 31102 and be detected by the sample detection probe 31103 arranged inside the cover.

A through sampling channel is provided at the center of the communication cylinder 503, the upper positioning board 501 and the lower positioning board 502, which is the communication end; a fixed adsorption layer 506 matching the movable adsorption seat 31101 is provided at the upper end of the sampling channel, a pressure increasing sleeve 507 acting on the one-way pressure valve 31105 is provided at the lower end, and a water blocking member 508 is provided at the bottom.

[0043] It should be further noted that the fixed adsorption layer 506 is a metal layer located in the second positioning groove and is clamped and adsorbed with the energized fixed adsorption seat 31108.

[0044] It should be further noted that the second cylinder 313 is fixed on the cleaning ring 312 and is connected to the upper positioning board 501 through a telescopic rod to drive the communication cylinder 503, the upper positioning board 501 and the lower positioning board 502 to move up and down.

[0045] It should be further noted that the water blocking member 508 includes a third cylinder located on the lower positioning board 502 and a plug that is driven by the third cylinder to lift and cover the sampling channel opening.

[0046] It should be further noted that as Figure 10 shown, the cleaning ring 312 includes a ring body 31201 arranged around the communication cylinder 503; cleaning brushes 31203 and vibrators 31202 that are in one-to-one correspondence with the positions of the water environment monitors 504 are provided on the ring body 31201.

[0047] It should be further noted that as Figure 11 shown, a pressure increasing cavity 509 with a small upper part and a large lower part is provided in the pressure increasing sleeve 507.

[0048] When the bottle body 31104 moves close to the sampling channel, the fixed adsorption seat 31108 disengages from the movable adsorption seat 31101 and adsorbs the fixed adsorption layer 506, which is fixed in the second positioning groove. The one-way pressure valve 31105 at the bottom communicates with the pressure increasing sleeve 507. The plug opens, and the communication cylinder 503 descends and extends into the water. On the one hand, the water environment monitor 504 is exposed to monitor the surrounding water environment. On the other hand, water enters the sampling channel from the bottom and is further pressurized through the pressure increasing cavity 509, and then can enter the bottle body 31104 through the one-way pressure valve 31105. When sampling and monitoring are completed, the plug seals, and the communication cylinder 503 rises and returns to the chamber. On the one hand, the water environment monitor 504 is retracted, and the cleaning brush 31203 cleans it through vibration. On the other hand, the energized fixed adsorption seat 31108 descends and adsorbs the movable adsorption seat 31101. The bottle body 31104 leaves the sampling channel.

[0049] As Figure 12 shown, the floating component 2 includes a floating board 201, an inflatable ring 203 located on the outer periphery of the floating board 201, and a solar energy seat 204 located on the top of the floating board 201; the control box 4 is located on the solar energy seat 204. The device uses clean energy, which is energy-saving and environmentally friendly.

[0050] As Figure 12 and Figure 4 shown, the stretching connecting piece 1 is a connecting steel rope, and multiple groups are arranged around the outer peripheries of the floating component 2 and the sinking component 3; an adjusting piece one 202 for connecting and adjusting the top end of the connecting steel rope is arranged on the floating board 201; an adjusting piece two 304 for connecting and adjusting the bottom end of the connecting steel rope is arranged on the upper mounting ring 302.

[0051] It should be further noted that both the adjusting piece one 202 and the adjusting piece two 304 drive the wire winding roller to rotate through a motor to adjust the length of the connecting steel rope. By adjusting the lengths of the connecting steel ropes at different positions, the positions and angles of monitoring and sampling are changed.

[0052] Embodiment 2: In this embodiment, a water pollution monitoring system is proposed, which adopts the water pollution monitoring instrument described in Embodiment 1, and includes a position adjustment module, an angle adjustment module, an environmental monitoring module, a sampling and detection module, and a control module. The position adjustment module controls the self-weight by adjusting the water absorption amount of the water absorption space to control the position of the sinking component 3; the angle adjustment module controls the angle of the sinking component 3 by adjusting the length of the stretching connecting piece 1; the environmental monitoring module monitors the water pollution environment by exposing the monitoring end; the sampling and detection module separates the sampling container from the sampling component through the communication end, makes it extend into the water for sampling and then resets and detects; in the control module, the control box 4 controls the work of each module of the system on the one hand, and obtains monitoring and sampling data on the other hand to analyze the water pollution situation.

[0053] Embodiment 3: In this embodiment, a water pollution monitoring method is proposed, which adopts the water pollution monitoring instrument described in Embodiment 1, and the steps are as follows:

[0058] S5. The plug is opened, and the connecting cylinder 503 descends and extends into the water. On the one hand, the water environment monitor 504 is exposed to monitor the surrounding water environment.
