Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing devices, specifically a water quality testing device for aquaculture. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to aquatic product under artificial feeding and management. Water quality testing devices are special instruments used to replace routine water quality testing. They are suitable for concentration testing in large, medium, and small water plants, industrial and mining enterprises, swimming pools, disease control centers, and domestic or industrial water. Water quality testing devices are used to test the water quality of aquaculture to ensure a stable growth environment for aquatic products.

[0003] A search revealed an application with application number 202322926273.6 for a water quality testing device for aquaculture. This device, through its testing mechanism, is capable of testing water quality at different depths. By testing water quality at different depths, it addresses the problem that current water quality testing devices typically test water at a fixed depth, thus improving the accuracy of aquaculture water testing. However, when testing water at different depths, water from other depths may remain on the inner walls of the testing chamber, hoses, and rigid pipes within the device. This mixing of water from different depths affects the accuracy of the test. Additionally, the filter holes on the iron ball are easily clogged by debris in the water, affecting the water sample collection speed. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a water quality testing device for aquaculture to solve the technical problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality testing device for aquaculture, comprising a support plate, a support frame connected to the top of the support plate, a negative pressure tank at the top of the support frame, a vacuum pump and an air pump at the top of the negative pressure tank, a first connecting pipe and a water outlet pipe connected to the bottom of the negative pressure tank, a testing box located inside the support frame, a detector located at the top of the testing box, a drain pipe connected to one side of the bottom of the testing box, a motor located inside the support frame, a winding wheel connected to the output end of the motor, a traction rope connected to the outside of the winding wheel, a sampling component located at one end of the traction rope, the sampling component comprising a traction ring, a housing connected to the bottom of the traction ring, a second connecting pipe located on one side of the housing, a sampling cylinder connected to the bottom of the housing, a filter screen connected to the inner wall of the sampling cylinder, a rotating shaft connected inside the housing, a fan blade connected above the outer surface of the rotating shaft, and a scraper connected below the outer surface of the rotating shaft via a bushing.

[0006] Furthermore, a float is provided at the bottom of the support plate, and solenoid valves are connected to the outer surfaces of the first connecting pipe, the water outlet pipe, and the drain pipe.

[0007] By adopting the above technical solution, the staff placed the float in the water area to be tested. The float provided buoyancy to the device, allowing it to float on the water surface. By opening or closing the solenoid valves in sequence, the flow of water and air in the first connecting pipe, the outlet pipe, and the drain pipe was controlled.

[0008] Furthermore, a processor is provided at the bottom of the support frame, and the vacuum pump, air pump, solenoid valve, motor and detector are all electrically connected to the processor.

[0009] By adopting the above technical solution, the vacuum pump, air pump, solenoid valve, motor, and detector are remotely controlled by the processor to start and stop. During sampling and testing, the motor is started, driving the winding wheel to rotate at the motor output end. The sampling component is lowered into the water by the traction rope until it reaches the required sampling depth. At this time, the vacuum pump is turned on to extract the air from the negative pressure tank to create a vacuum. The solenoid valve on the first connecting pipe is opened, and under the action of negative pressure, the water sample enters the sampling component and is transported through the delivery pipe to the first connecting pipe and then into the negative pressure tank. The solenoid valve on the outlet pipe is opened and the detector is started. The water sample enters the testing chamber through the outlet pipe, and the detector begins to test the water sample. After the test is completed, the solenoid valve on the drain pipe is opened to discharge the water sample. The air pump is turned on to continuously draw air into the negative pressure tank, and the air is used to discharge the water sample from the first connecting pipe, delivery pipe, and sampling component to avoid mixing with the water sample collected next time, which would affect the testing accuracy.

[0010] Furthermore, the first connecting pipe and the second connecting pipe are connected by a delivery pipe, and the delivery pipe is a flexible hose.

[0011] By adopting the above technical solution, the delivery pipe is connected to the first connecting pipe and the second connecting pipe respectively by clamps. The delivery pipe is a PU pipe. Taking advantage of the flexible bending properties of the PU pipe, it is convenient to follow the sampling component into the water and deliver the water sample to the vacuum tank.

[0012] Furthermore, the scraper is provided in two parts, and both scrapers are in contact with the outer surface of the filter screen.

[0013] By adopting the above technical solution, during sampling, the fan blades drive the rotating shaft to rotate under the influence of water flow, which in turn causes the bushing to drive the scraper to rotate. The scraper removes the debris adsorbed on the surface of the filter screen, preventing the debris from clogging the filter screen and reducing the amount of water entering the sampling tube, thus affecting the sampling speed.

[0014] Furthermore, the bottom of the housing is connected to the sampling cylinder through a through hole.

[0015] By adopting the above technical solution, during sampling, under negative pressure, the water sample enters the sampling cylinder and then enters the housing through the through hole, thereby causing the fan blade to rotate, which in turn drives the scraper to clean the surface of the filter screen. During backwashing, the gas and residual water sample are discharged into the sampling cylinder through the through hole. The gas flushes away the debris on the filter screen mesh, preventing the debris from clogging the filter screen mesh.

[0016] Furthermore, a signal receiver and a signal transmitter are respectively provided on both sides of the processor, and the processor, signal receiver, and signal transmitter are electrically connected to an external terminal.

[0017] By adopting the above technical solution, staff can remotely control the terminal, transmit signals to the terminal through a signal receiver and a signal transmitter, and control the start or stop of solenoid valves, vacuum pumps, air pumps, detectors and motors through a processor, thus achieving remote control.

[0018] Furthermore, both the float and the support plate have openings, and the size of the openings is much larger than the size of the sampling components.

[0019] By adopting the above technical solution, the sampling component enters the water through the opening, which can avoid friction between the traction rope and the support plate and float, and between the sampling component and the support plate and float, thereby extending the service life of the device.

[0020] Furthermore, the traction rope is made of steel wire.

[0021] By adopting the above technical solutions, the wire rope has advantages such as high strength, wear resistance, and high compressive strength, and is easy to maintain while having a longer service life.

[0022] Furthermore, the bottom of the testing box is inclined.

[0023] By adopting the above technical solution, after the test is completed, the solenoid valve on the drain pipe is opened, and the water sample is discharged from the test box from the drain pipe. The inclined setting facilitates the rapid discharge of the water sample from the test box, while avoiding water sample residue from mixing with the next batch of water samples, which would affect the test accuracy.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model is equipped with a vacuum pump, an air pump, and a vacuum tank. During sampling and testing, the vacuum pump creates a vacuum in the vacuum tank, and the water to be tested is drawn into the vacuum tank using negative pressure. Finally, the water flows into the testing chamber for testing. The air pump blows air into the vacuum tank to backflush the testing chamber, the water outlet pipe, the first connecting pipe, the delivery pipe, and the sampling cylinder, thereby expelling any residual water inside. This prevents the water sample from mixing with the water sample during the next sampling, making the test results more accurate. At the same time, when the residual water sample and air are expelled, the filter screen is cleaned to prevent debris from clogging the filter screen.

[0026] 2. This utility model is equipped with fan blades, a rotating shaft, and a scraper. The fan blades are driven to rotate by the water flow, which in turn drives the rotating shaft to rotate, thereby causing the scraper to rotate outside the sampling cylinder. The rotation of the scraper removes the debris adsorbed on the outer surface of the sampling cylinder, preventing debris from clogging the filter screen and affecting sampling, thus improving the sampling speed.

[0027] 3. This utility model is equipped with a winding wheel and a traction rope. Driven by the output of a motor, the traction rope is wound up by the winding wheel, thereby controlling the depth of the sampling component in the water, so as to achieve the purpose of sampling and testing water at different depths and improving the accuracy of the test.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: A device for testing water quality in aquaculture, such as... Figures 1-4As shown, the system includes a support plate 2, a support frame 3 connected to the top of the support plate 2, a negative pressure tank 4 on the top of the support frame 3, a vacuum pump 5 and an air pump 6 on the top of the negative pressure tank 4, a first connecting pipe 7 and a water outlet pipe 8 connected to the bottom of the negative pressure tank 4, a detection box 10 inside the support frame 3, a detector 11 on the top of the detection box 10, a drain pipe 12 connected to one side of the bottom of the detection box 10, a motor 14 inside the support frame 3, a winding wheel 15 connected to the output end of the motor 14, a traction rope 16 connected to the outside of the winding wheel 15, the traction rope 16 being made of steel wire, which has advantages such as high strength, wear resistance, and high compressive strength, is easy to maintain and has a longer service life, a sampling component 17 at one end of the traction rope 16, the sampling component 17 including a traction ring 1701, the bottom of the traction ring 1701 being connected to a shell The device consists of a body 1702, a second connecting pipe 1703 on one side, a sampling cylinder 1707 connected to the bottom of the body 1702, a filter screen 1708 connected to the inner wall of the sampling cylinder 1707, a rotating shaft 1706 connected inside the body 1702, a fan blade 1705 connected above the outer surface of the rotating shaft 1706, and a scraper 1710 connected below the outer surface of the rotating shaft 1706 via a bushing 1709. A float 1 is provided at the bottom of the support plate 2. Solenoid valves 13 are connected to the outer surfaces of the first connecting pipe 7, the outlet pipe 8, and the drain pipe 12. When the operator places the float 1 in the water area to be tested, the float 1 provides buoyancy to the device, causing the device to float on the water surface. By opening or closing the solenoid valves 13 in sequence, the flow of water samples and air in the first connecting pipe 7, the outlet pipe 8, and the drain pipe 12 can be controlled.

[0036] See Figure 1 In the above embodiment, a processor 18 is provided at the bottom of the support frame 3, and the vacuum pump 5, air pump 6, solenoid valve 13, motor 14, and detector 11 are all electrically connected to the processor 18. The processor 18 remotely controls the opening and closing of the vacuum pump 5, air pump 6, solenoid valve 13, motor 14, and detector 11. During sampling and testing, the motor 14 is started, and the winding wheel 15 is driven to rotate at the output end of the motor 14. The sampling component 17 is placed in the water through the traction rope 16 until the sampling component 17 is lowered to the required sampling depth. At this time, the vacuum pump 5 is turned on to extract the air in the negative pressure tank 4 to create a vacuum state, and the second vacuum pump 5 is turned on. Under negative pressure, the solenoid valve 13 on the connecting pipe 7 allows the water sample to enter the sampling component 17 and be transported through the delivery pipe 9 to the first connecting pipe 7 and then into the negative pressure tank 4. The solenoid valve 13 on the outlet pipe 8 is opened and the detector 11 is started. The water sample enters the detection chamber 10 through the outlet pipe 8, and the detector 11 begins to detect the water sample. After the detection is completed, the solenoid valve 13 on the drain pipe 12 is opened to discharge the water sample. The air pump 6 is turned on to continuously draw air into the negative pressure tank 4. The air is used to discharge the water sample in the first connecting pipe 7, the delivery pipe 9 and the sampling component 17 to avoid mixing with the water sample collected next time, which would affect the detection accuracy.

[0037] See Figure 1 In the above embodiment, the first connecting pipe 7 and the second connecting pipe 1703 are connected by a delivery pipe 9, and the delivery pipe 9 is a flexible hose. The delivery pipe 9 is connected to the first connecting pipe 7 and the second connecting pipe 1703 by a clamp. The delivery pipe 9 is a PU tube. Utilizing the flexible bending properties of the PU tube, it is convenient to follow the sampling component 17 into the water and deliver the water sample to the vacuum tank.

[0038] See Figure 2 , Figure 3 and Figure 4 In the above embodiment, two scrapers 1710 are provided, and the two scrapers 1710 are in contact with the outer surface of the filter screen 1708. During sampling, the fan blade 1705 drives the rotating shaft 1706 to rotate under the drive of the water flow, thereby causing the bushing 1709 to drive the scraper 1710 to rotate. The scraper 1710 scrapes away the debris adsorbed on the surface of the filter screen 1708, avoiding the debris from clogging the filter screen 1708, which would reduce the water flow into the sampling cylinder 1707 and affect the sampling speed.

[0039] See Figure 3 In the above embodiment, the bottom of the housing 1702 is connected to the sampling cylinder 1707 through the through hole 1704. During sampling, under negative pressure, the water sample enters the sampling cylinder 1707 and then enters the housing 1702 through the through hole 1704, thereby causing the fan blade 1705 to rotate, which in turn drives the scraper 1710 to clean the surface of the filter screen 1708. During backwashing, the gas and residual water sample are discharged into the sampling cylinder 1707 through the through hole 1704. The gas flushes away the debris on the mesh of the filter screen 1708, preventing the debris from clogging the holes of the filter screen 1708.

[0040] See Figures 1-4 In the above embodiment, a signal receiver 19 and a signal transmitter 20 are respectively provided on both sides of the processor 18, and the processor 18, the signal receiver 19 and the signal transmitter 20 are electrically connected to an external terminal. The staff can remotely control the terminal, transmit signals to the terminal through the signal receiver 19 and the signal transmitter 20, and control the start or stop of the solenoid valve 13, the vacuum pump 5, the air pump 6, the detector 11 and the motor 14 through the processor 18 to achieve remote control.

[0041] See Figure 1 In the above embodiment, both the float 1 and the support plate 2 are provided with openings, and the size of the openings is much larger than the size of the sampling component 17. The sampling component 17 enters the water through the openings, which can avoid friction between the traction rope 16 and the support plate 2 and the float 1, and between the sampling component 17 and the support plate 2 and the float 1, thereby extending the service life of the device.

[0042] Example 2: To avoid water sample residue remaining in the testing chamber 10 after testing, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 The bottom of the test chamber 10 is set at an angle. After the test is completed, the solenoid valve 13 on the drain pipe 12 is opened, and the water sample is discharged from the test chamber 10 through the drain pipe 12. The angled setting facilitates the rapid discharge of the water sample from the test chamber 10, while avoiding water sample residue from mixing with the next batch of water samples, which would affect the test accuracy.

[0043] The implementation principle of this utility model is as follows: The staff places the float 1 in the water area to be tested. The float 1 provides buoyancy to the device, causing it to float on the water surface. During sampling, the motor 14 is started, driving the winding wheel 15 to rotate at the output end of the motor 14. The sampling component 17 is lowered into the water via the traction rope 16 until it reaches the required sampling depth. At this time, the vacuum pump 5 is turned on to extract the air from the negative pressure tank 4, creating a vacuum. The solenoid valve 13 on the first connecting pipe 7 is opened. Under negative pressure, water flows through the filter screen 1708 and enters the sampling cylinder 1707. It then enters the housing 1702 through the through hole 1704. The water flow drives the fan blade 1705 to rotate. Driven by the fan blade 1705, the rotating shaft 1706 drives the scraper 1710 to rotate, cleaning the impurities adsorbed on the outer surface of the sampling cylinder 1707. The water sample in the housing 1702 is transported to the first connecting pipe 9. After the first connecting pipe 7 enters the negative pressure tank 4, the solenoid valve 13 on the first connecting pipe 7 is closed after a period of time, the solenoid valve 13 on the outlet pipe 8 is opened and the detector 11 is started. The water sample enters the detection box 10 through the outlet pipe 8, and the detector 11 starts to detect the water sample. After the detection is completed, the solenoid valve 13 on the drain pipe 12 is opened to discharge the water sample. The air pump 6 is turned on to continuously draw outside air into the negative pressure tank 4. The residual water sample in the outlet pipe 8, detection box 10, first connecting pipe 7, delivery pipe 9 and shell 1702 is discharged by the gas. At the same time, the gas enters the sampling cylinder 1707 to clean the mesh of the filter screen 1708 and prevent debris from clogging the filter screen 1708. When it is necessary to detect water samples at other depths, the motor 14 is started to reverse and the depth of the sampling component 17 in the water is adjusted by the traction rope 16. The above operation is repeated to detect water samples at different depths in turn, thereby improving the detection accuracy.
