Description

Technical Field

[0001] The present invention belongs to the technical field of water quality detection equipment, and particularly relates to a vortex-type on-line water quality monitoring sensor cleaning system. Background Art

[0002] Traditional fish farming involves feeding fish with single-nutrient grains such as corn, sweet potatoes, and rapeseed meal based on experience. Due to backward grain processing technology, low utilization rate, and large waste, fish grow slowly, and the feed conversion ratio is very high. It takes several catties of grain to grow one catty of fish. In fact, the water content of fresh animals is mostly between 60% and 95%. If the water content of fresh fish is calculated at 70%, actually only 3 taels of dry feed is needed to grow one catty of fish, and there will be a large amount of fish feces and residual bait. If beneficial microorganisms are not timely put in to decompose and recycle, garbage will accumulate, harmful algae will grow wildly, resulting in water quality deterioration and water body stench, and fish will lose their natural nutrition and flavor.

[0003] Ecological fish farming utilizes rich beneficial microorganisms in water to establish a complete ecological cycle system. In this process, an on-line water quality monitoring system is needed to monitor water quality and dissolved oxygen content and other indicators in real time, analyze and balance the components in water (organic matter and inorganic matter), and maintain the balance and stability of the four phases among decomposers (bacterial phase), producers (algal phase), and consumers (zooplankton and fish). By quantitatively feeding high-quality digestible floating feed, regularly putting in beneficial bacteria (EM bacteria, Bacillus, photosynthetic bacteria, etc.), cultivating beneficial insects (zooplankton), beneficial algae (diatoms, chlorella, etc.), and aquatic plants, the water quality is purified, the quality and yield of fish are improved, and the sustainable development of green waters and lush mountains is ensured relying on the natural ecological system, achieving a win-win situation.

[0004] However, after long-term use of the on-line water quality monitoring system, its internal sensors and water intake pipelines are easily contaminated by organisms (growing fungi and algae), resulting in the growth of microorganisms in the sensitive elements of the sensors or the blockage of the water intake pipelines, leading to a gradual decrease in water flow, and ultimately resulting in inaccurate or invalid monitoring data, which has now become an industry problem.

[0005] Therefore, the present invention provides a vortex-type on-line water quality monitoring sensor cleaning system, which can perform one-to-one high-pressure vortex cleaning on the sensors online, ensuring both the stability and reliability of water quality monitoring data and extending the service life of the monitoring equipment.

A chamber for generating a vortex is provided between the secondary nozzle and the primary nozzle, and vortex water outlet holes communicating with the cleaning cavity are provided on the top surface of the secondary nozzle.

[0012] A first sealing ring for sealing connection with the nozzle connector is provided on the outer wall of the pipe connector, and an embedded ring groove is provided on the outer wall of the primary nozzle. A second sealing ring for sealingly fitting with the inner wall of the secondary nozzle is provided in the embedded ring groove.

[0013] Further, a sensor installation hole communicating with the cleaning cavity is provided on the side wall of the vortex cleaning tank. The water quality monitoring sensor is installed in the sensor installation hole. There are at least two water quality monitoring sensors, including a dissolved oxygen sensor and a pH sensor.

[0014] Further, the water quality filter includes a filter core, a first sleeve and a second sleeve respectively sleeved at both ends of the filter core, a sealing pipe cap provided outside the first sleeve, and a connector provided outside the second sleeve. A rubber part is embedded in the filter cavity of the filter core.

[0015] Furthermore, the double-pump water inlet mechanism includes a first water inlet pipe and a second water inlet pipe respectively connected to the vortex cleaning tank.

[0017] Furthermore, the side wall of the cleaning chamber where the water quality monitoring sensor is installed is a flat wall, and the other side walls of the cleaning chamber are all arc-shaped walls. And a slope is provided between the flat wall and the arc-shaped wall. The inlet opening is formed on the slope, and the inclination angle of the slope is 45 - 60°.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention has a simple structure, is scientifically and reasonably designed, and is convenient to use. It solves the technical problem that the existing water quality monitoring sensor is easily contaminated by organisms and blocked by impurities, resulting in inaccurate detection data. It can clean the sensor one by one with high-pressure vortex at regular intervals, which not only ensures the stability and reliability of the water quality monitoring data, but also extends the service life of the monitoring equipment.

[0022] The present invention includes a floating ball and a vortex cleaning tank. Due to the buoyancy, the floating ball can float the whole cleaning system on the breeding water surface, and at the same time, it can also isolate the internal and electrical equipment from the water body. The present invention pumps the breeding water into the vortex cleaning tank, and the water quality monitoring sensor in the vortex cleaning tank completes the real-time detection of various indexes of the breeding water body, providing breeding reference for farmers.

[0023] In natural waters, especially in aquaculture water bodies, there are various microorganisms, metabolites such as feces, phytoplankton and zooplankton, as well as corpses, and various kinds of garbage discharged into the water. Inevitably, they will accumulate in the vortex cleaning tank, thereby causing biological mixed pollution on the surface of the sensor and clogging of the inlet and outlet, ultimately resulting in inaccurate or invalid monitoring data. For this reason, the present invention adopts a vortex cleaning mechanism, which can not only perform high-pressure cleaning on the cleaning chamber and the water quality monitoring sensor regularly, avoiding the accumulation of dirt in the tank and the pollution of the sensitive components of the water quality monitoring sensor. The water sprayed by the vortex cleaning mechanism is in a vortex shape, which not only has a large cleaning area, but also can perform one-to-one high-pressure flushing on the sensitive components of the water quality monitoring sensor. The present invention also adopts a double-pump water inlet mechanism to filter out impurities such as fish, shrimps, weeds, and branches before the aquaculture water enters the vortex cleaning tank, which can extend the service life of the monitoring equipment, effectively reduce the maintenance frequency and maintenance cost. The water inlet mechanism is of a double-pump structure, avoiding the over-fatigue damage of a single pump running for a long time and ensuring the overall use stability of the system.

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] As Figures 1-11 shown, a vortex - type on - line water quality monitoring sensor cleaning system provided by the present invention solves the technical problem that existing water quality monitoring sensors are easily contaminated by organisms and blocked by impurities, resulting in inaccurate detection data. It can perform one - to - one high - pressure vortex cleaning on the sensor at regular intervals, which not only ensures the stability and reliability of water quality monitoring data but also extends the service life of the monitoring equipment.

[0041] The present invention includes a floating ball 1 and a vortex cleaning tank 2 arranged inside the floating ball 1. A cleaning cavity 3 is arranged inside the vortex cleaning tank 2. A water quality monitoring sensor 4 with a sensitive element end located in the cleaning cavity 3 is installed on one side wall of the vortex cleaning tank 2. A vortex cleaning mechanism corresponding to the water quality monitoring sensor 4 is connected to the other side wall. A double - pump water inlet mechanism for monitoring water inlet is connected to the bottom wall, and a drainage mechanism for monitoring water outlet is connected to the back. The structure is simple and the operation is stable.

[0042] The overall system of the present invention floats on the aquaculture water surface under the buoyancy of the floating ball 1, which not only avoids the water isolation of various mechanisms inside the floating ball 1, especially electrical equipment, but also facilitates the operation of taking in and putting out the overall system in the aquaculture water body. The connection between the used floating ball 1 and the vortex cleaning tank 2 can adopt the connection structure and connection method in a patent applied by the applicant earlier. The patent application number is: 201821213233.X, and the patent name is: An on - line water quality monitoring device for aquaculture water. Therefore, the connection between the floating ball and the vortex cleaning tank, etc. will not be elaborated here.

[0043] The vortex cleaning mechanism of the present invention includes a water quality filter 5, a filtered water outlet pipe 6 led out from the filter cavity of the water quality filter 5, a high - pressure diaphragm pump 7 connected to the filtered water outlet pipe 6, and a vortex high - pressure cleaning head connected to the high - pressure diaphragm pump 7. The present invention locally uses the aquaculture water body as the cleaning water. After being filtered by the water quality filter 5, the aquaculture water body is pumped into the vortex high - pressure cleaning head by the high - pressure diaphragm pump 7 and finally used for cleaning the cleaning cavity 3 and the water quality monitoring sensor 4. The vortex high - pressure cleaning head includes at least one cleaning water inlet pipe 8 connected to the outlet pipe of the high - pressure diaphragm pump 7, a pipe connector 9 embedded at the end of the cleaning water inlet pipe 8, a nozzle connector 10 threadedly connected to the pipe connector 9, a primary nozzle 11 arranged on the nozzle connector 10, and a secondary nozzle 12 threadedly connected to the primary nozzle 11. A nozzle installation hole 21 is opened on the side wall of the vortex cleaning tank 2, and the secondary nozzle 12 is installed in the nozzle installation hole 21. A circle of water outlet holes 113 is circumferentially opened at the head of the primary nozzle 11, and a plurality of water guide grooves 114 are arranged on the top surface of the primary nozzle 11. The water guide grooves 114 are parallel to the tangent of the top surface circle of the primary nozzle 11. A chamber 13 for generating a vortex is arranged between the secondary nozzle 12 and the primary nozzle 11, and a vortex water outlet hole 121 communicating with the cleaning cavity 3 is opened on the top surface of the secondary nozzle 12.

[0044] The cleaning water of the present invention is led out from a circle of water outlet holes 113 of the primary spray head 11 and enters the chamber 13 between the primary spray head 11 and the secondary spray head 12. When it reaches the water guide groove 114 perpendicular to the water flow direction, it starts to split. The water guide groove 114 is parallel to the tangent of the top surface circle of the primary spray head 11 and forms a spiral structure. At this time, the water body forms concentrated guiding water bodies and forms a swirling high-pressure cleaning water, which enters the cleaning chamber 3 through the swirling water outlet holes of the secondary spray head 12. The secondary spray head 12 and the primary spray head 11 can adjust the size of the chamber 13 through threads, and further adjust the water spraying amount and the swirling intensity. The high-pressure diaphragm pump 7 can be connected to multiple swirling high-pressure cleaning heads. The water outlet pipe of the high-pressure diaphragm pump 7 is connected to multiple cleaning water inlet pipes 8 through connectors such as tees or four-ways. Each cleaning water inlet pipe 8 is provided with a primary spray head 11 and a secondary spray head 12. The outer wall of the pipe connector 9 is provided with a first sealing ring 91 for sealing connection with the spray head connector 10. The outer wall of the primary spray head 11 is provided with an embedded ring groove 111, and a second sealing ring 112 for sealingly fitting with the inner wall of the secondary spray head 12 is arranged in the embedded ring groove 111.

[0045] A sensor installation hole 27 communicating with the cleaning chamber 3 is formed in the side wall of the swirling cleaning tank 2 of the present invention. The water quality monitoring sensor 4 is installed in the sensor installation hole 27. There are at least two water quality monitoring sensors 4, including a dissolved oxygen sensor 41 and a pH sensor 42. The water quality monitoring sensor 4 may also include, but is not limited to, other water quality monitoring index sensors such as a turbidity sensor, a salinity sensor, an ORP sensor or a chlorophyll sensor. The number and installation height of the sensor installation holes 27 are the same as those of the spray head installation holes 21, that is, a swirling high-pressure cleaning head is arranged at the opposite position of each water quality monitoring sensor 4 for one-to-one positioning cleaning.

[0046] The water quality filter 5 of the present invention includes a filter element 51, a first sleeve 52 and a second sleeve 53 respectively sleeved at both ends of the filter element 51, a sealing pipe cap 54 arranged outside the first sleeve 52, and a connector 55 arranged outside the second sleeve 53. A rubber part 56 is embedded in the filtering cavity of the filter element 51. The filtered water outlet pipe 6 sequentially passes through the connector 55, the rubber part 56 and extends into the filtering cavity of the filter element 51. A water separation plate 57 is arranged on the top surface of the filter element 51. When the high-pressure diaphragm pump 7 is started, a negative pressure will be formed in the filtering cavity of the filter element 51, and the aquaculture water body will filter and penetrate from the outside of the filter element 51 to obtain the cleaned water with impurities removed and stored in the filtering cavity. When needed, the high-pressure diaphragm pump 7 pumps the cleaned water to remotely clean the water quality monitoring sensor 4, eliminating frequent manual maintenance and providing more stable and reliable real-time online monitoring data for production and life. Since the filter element 51 is of a cylindrical structure, to ensure the storage of filtered water, a sealing pipe cap 54 is arranged at the bottom, a connector 55 is arranged at the top, and a rubber part 56 is arranged at the top of the filtering cavity, so that the filtering cavity forms a relatively sealed cavity. The first sleeve 52 and the second sleeve 53 ensure the connection stability of the sealing pipe cap 54 and the connector 55. Since the amount of water required for filtering and cleaning is not large and it is not used continuously, the filter element 51 is preferably a PP polypropylene filter cotton with a length of 250 mm, an inner diameter of 29 mm, an outer diameter of 58 mm, and a filtering pore diameter of 1 μm. Water with a diameter of about 0.4 nm can easily pass through the 1-μm filtering pores. The first sleeve 52, the second sleeve 53 and the sealing pipe cap 54 are all preferably made of PVC63. The connector 55 is a PVC63 to 32 pipe, and the water separation plate 57 is a PVC plate.

[0047] The double-pump water inlet mechanism of the present invention includes a first water inlet pipe 14 and a second water inlet pipe 15 respectively connected to the vortex cleaning tank 2. A first water pump 16 is provided on the first water inlet pipe 14, and the first water pump 16 is connected to a first filter screen 17. A second water pump 18 is provided on the second water inlet pipe 15, and the second water pump 18 is connected to a second filter screen 19. Since the water body monitoring in aquaculture is continuous and uninterrupted, and the water pumps used all operate at high intensity and for a long time, it is extremely easy to cause damage to the water pumps. The double-pump structure of the present invention can avoid excessive damage caused by single-pump operation. The first water pump 16 and the second water pump 18 can operate alternately, improving the service life and operation stability of the system. Both the first water inlet pipe 14 and the second water inlet pipe 15 are made of copper pipes to replace traditional plastic pipes. Both the first water pump 16 and the second water pump 18 are one-word brass water pumps to replace traditional cross-shaped plastic water pumps. In addition, the vortex cleaning tank 2 and the cleaning chamber 3 used in the present invention are also made of copper or copper alloy. Copper and copper alloy have the functions of sterilization, insecticidal, and algicidal, and can greatly delay biological pollution. An inlet 22 communicating with the cleaning chamber 3 is opened at the bottom of the vortex cleaning tank 2 of the present invention. An inlet connector 23 is provided at the inlet 22, and the inlet connector 23 is respectively connected to the first water inlet pipe 14 and the second water inlet pipe 15 through a U-shaped tee 24. The above-mentioned dissolved oxygen sensor 41 is located directly below the pH sensor 42 and is directly opposite to the inlet 22 up and down.

[0048] The first filter screen 17 and the second filter screen 19 used in the present invention can effectively filter and prevent particulate matter with a particle size of more than 1 mm, avoiding the damage of particulate matter to the water quality monitoring sensor 4 and affecting the monitoring data. The first filter screen 17 and the second filter screen 19 have the same structure and can adopt the structure in a patent applied by the applicant earlier. The patent application number is: 201922223980.2, and the patent name is: An on-line cleaning device for water quality monitoring sensors. Therefore, the specific structure and filtering principle of the first filter screen 17 and the second filter screen 19 are not described in detail here.

[0049] In the cleaning chamber 3 of the present invention, the side wall for installing the water quality monitoring sensor 4 is a flat wall, and the other side walls are arc-shaped walls. And a slope 31 is provided between the flat wall and the arc-shaped wall. The inlet 22 is opened on the slope 31, and the inclination angle of the slope 31 is 45 - 60°. The arc-shaped wall not only avoids cleaning dead corners, but also is conducive to the vortex flushing of the monitoring water and the cleaning water along the arc-shaped wall, reducing the high-pressure loss and greatly improving the cleaning efficiency.

[0050] The drainage mechanism of the present invention includes a drain pipe 20 and a flow meter 25 provided on the drain pipe 20. An outlet 26 communicating with the cleaning chamber 3 is formed on the back of the vortex cleaning tank 2, and the drain pipe 20 is connected to the outlet 26. The double-pump water inlet mechanism, the unique cleaning chamber 3 and the drainage mechanism of the present invention can, on the one hand, play an online monitoring function, pump the aquaculture water into the cleaning chamber 3 and complete real-time online monitoring of relevant indicators through the water quality monitoring sensor 4, and on the other hand, play a vortex cleaning role to prevent various impurities from depositing inside the cleaning chamber 3. The water inlet 22 is the lowest point of the cleaning chamber 3. When the first water pump 16 or the second water pump 18 stops working, the water in the cleaning chamber 3 is quickly emptied reversely through the water inlet pipe, the water pump and the filter screen. When the water pump is turned on, the inlet water can be sprayed at an angle of 45-60 degrees to the water quality monitoring sensor 4 at the water inlet 22 and generate a clockwise high-speed rotating vortex along the inner wall of the cleaning chamber 3, and is discharged horizontally as much as possible at the outlet 26 in the center of the vortex, that is, in the center of the cleaning chamber 3. The rotating surface is parallel to the earth's gravitational line and forms a 90-degree right angle with the horizontal drainage, so that a vortex is generated. In this way, the surrounding water and other impurities are promoted to converge towards the center and quickly discharged.

[0051] A power supply 28 and a microprocessor 29 connected to the power supply 28 are provided inside the float ball 1 of the present invention. The microprocessor 29 is electrically connected to the water quality monitoring sensor 4, the vortex cleaning mechanism, the double-pump water inlet mechanism and the drainage mechanism respectively. Specifically, the microprocessor 29 is electrically connected to the dissolved oxygen sensor 41, the pH sensor 42, the high-pressure diaphragm pump 7, the first water pump 16, the second water pump 18 and the flow meter 25 respectively. The microprocessor 29 controls the opening and closing and working frequency of the high-pressure diaphragm pump 7, the first water pump 16 or the second water pump 18. The high-pressure diaphragm pump 7 and the first water pump 16 or the second water pump 18 are opened at intervals to achieve accurate monitoring and effective cleaning. At the same time, the flow meter 25 is used to monitor the water flow rate and feedback it to the microprocessor 29. When the microprocessor 29 receives abnormal information that the water flow rate is too small, it controls the high-pressure diaphragm pump 7 and the first water pump 16 or the second water pump 18 to stop running to avoid idling. The microprocessor 29 adopts STM32F103V8.

[0052] The high-pressure diaphragm pump 7, the one-word brass water pump, the dissolved oxygen sensor 41, the pH sensor 42, the power supply 28 and the flow meter 25 used in the present invention are all existing known electrical equipment and can be directly purchased and used in the market. Their structures, circuits and control principles are all existing known technologies. Therefore, the structures, circuits and control principles of the high-pressure diaphragm pump 7, the one-word brass water pump, the dissolved oxygen sensor 41, the pH sensor 42, the power supply 28 and the flow meter 25 will not be elaborated here.

[0053] In addition to being applied to the aquaculture industry, the technology of the present invention is applicable to environments where sensors are required in water in technical fields such as environmental monitoring, weather forecasting and agricultural production.

[0054] Finally, it should be noted that the above embodiments are only the preferred embodiments of the present invention to illustrate the technical solutions of the present invention, rather than limiting it, let alone limiting the patent scope of the present invention; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention; that is to say, any meaningless changes or polishing made on the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention; in addition, directly or indirectly applying the technical solutions of the present invention to other related technical fields shall similarly be included in the patent protection scope of the present invention.
