Description

Technical Field

[0001] This invention belongs to the field of livestock farming water testing technology, and discloses a rapid testing device and method for livestock farming water. Background Technology

[0002] Rapid testing devices for livestock water simplify complex laboratory water quality analysis into routine operations that can be quickly performed at water sources or livestock sheds. This enables real-time control and dynamic management of livestock water quality, allowing for the detection of elevated concentrations of harmful substances such as nitrates, nitrites, and fluorides, or excessive levels of palatability and health indicators such as total hardness and sulfates, caused by environmental changes, pipeline contamination, or abnormal water sources. These devices are highly integrated and portable in their design, typically including sampling and pretreatment units (such as dedicated sampling bottles and filter heads), reagent and reaction units (individually packaged pre-made reagent kits or reagent sets), detection and sensing units (light sources, detectors, or sensors based on colorimetric or electrochemical methods), control and display units, and a portable power supply. All components are integrated into a sturdy carrying case to adapt to the complex environment of livestock farms.

[0003] Chinese invention patent application number CN202211253847.1 discloses a rapid on-site testing device and method for livestock farming water, including an outer shell and a control system. A tray base is installed inside the outer shell, and a rotating disk is rotatably mounted on the top of the tray base. Several placement grooves are provided on the edge of the rotating disk, which is connected to an intermittent drive mechanism. Vertical baffles are fixedly installed on the edge of the tray base. The outer shell also includes a low-temperature sample storage tank, a first reagent tank, a first water storage tank, a second reagent tank, a third reagent tank, a second water storage tank, a nitrite detection mechanism, and a sample bottle recovery box. This allows testing personnel to pre-prepare reagents such as distilled water, 4g / L p-aminobenzenesulfonic acid solution, and 2g / L naphthylethylenediamine hydrochloride solution, and pour them into the corresponding water storage tank and reagent tank. The collected water samples can then be directly tested on-site using the testing device.

[0004] However, the above-mentioned technical solution is equipped with several reagent boxes, sample bottles, and sample bottle recycling boxes. After each testing operation, a cleaning and maintenance operation is required. If the sample bottles, reaction containers, or sampling tools are not thoroughly cleaned, the residual reagents or reaction products may react directly with the new water sample or reagents. For example, when testing for chloride, if the sample bottle contains residual nitrates from the previous test, it may lead to inaccurate test results. This cross-contamination will render the test data worthless and affect the judgment of water quality. However, the testing process itself aims for speed, but the tedious subsequent cleaning, including disassembly, brushing, multiple rinsing, drying, and reassembly, often takes longer, which prolongs the overall cycle of rapid testing. This is particularly prominent in the high-frequency, multi-point daily water monitoring of aquaculture farms. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid detection device and method for livestock water. The device is arranged at the drinking nipple, water tank inlet, or water source to collect fresh water samples. A vortex magnetic pump and a sample inlet module allow the water sample to enter the collection and reuse tube assembly and the inner sample collection chamber. After the inlet is complete, the water quality detection module performs sample detection. The collected numerical signals are transmitted to a touch panel for display. When cleaning and maintaining the device, a vortex magnetic pump and a purified water supply module allow purified water to enter the collection and reuse tube assembly. The collection and reuse tube assembly sprays purified water to rinse the inner sample collection chamber and the various sensors in the water quality detection module. The waste liquid after rinsing is discharged through the discharge solenoid valve at the lower end of the inner sample collection chamber, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rapid testing device for livestock water includes a cylindrical shell, a base fixedly installed at the bottom of the cylindrical shell, a protective shell fixedly installed at the top of the cylindrical shell, an end plate fixedly installed at the opening at the top of the cylindrical shell, an inner sample collection chamber installed at the bottom of the end plate, a liquid discharge solenoid valve installed at the center of the lower end of the inner sample collection chamber, a vortex magnetic pump installed at the top of the end plate, a sample liquid inlet module installed at the inlet end of the vortex magnetic pump, and a purified water supply module installed on the outer wall of the cylindrical shell, which is also connected to the inlet end of the vortex magnetic pump. The inner sample collection chamber contains a liquid collection and reuse tube assembly. A water quality detection module is installed at the bottom of the end plate and is located outside the liquid collection and reuse tube assembly. A liquid outlet pipe is installed at the outlet end of the vortex magnetic pump, and the lower end of the liquid outlet pipe extends into the interior of the liquid collection and reuse tube assembly. A touch panel is installed at the top of the protective shell. The control output terminal of the touch panel is electrically connected to the control input terminal of the vortex magnetic pump, the purified water supply module, the sample liquid inlet module, and the liquid discharge solenoid valve, respectively. The input terminal of the touch panel is electrically connected to the output terminal of the water quality detection module.

[0007] The following are further optimizations of the above technical solution by the present invention: Several U-shaped seats are installed at equal intervals along the vertical and circumferential directions on the outer wall of the inner sample collection chamber, and bolts for connecting with the U-shaped seats are installed on the outer wall of the cylindrical shell.

[0008] Further optimization: The sample liquid inlet module consists of a C-tube and a No. 1 electromagnetic inlet valve. The C-tube is installed on one side inside the protective shell, and one end of the C-tube is connected to the inlet end of the vortex magnetic pump. The No. 1 electromagnetic inlet valve is installed on the other end of the C-tube.

[0009] Further optimization: The water supply module includes a storage tank fixedly installed on the outer wall of the cylindrical shell. A second electromagnetic inlet valve is installed at the middle position of the C-shaped pipe. An L-shaped inlet pipe is installed at the lower end of the second electromagnetic inlet valve. One end of the L-shaped inlet pipe passes through the outside of the protective shell and extends into the inside of the storage tank.

[0010] Further optimization: The outer wall of the protective shell is provided with ventilation holes and windows for heat dissipation of the vortex magnetic pump.

[0011] Further optimization: The base includes a hollow I-beam fixedly installed at the bottom of the inner sample collection chamber, and multiple foot supports are evenly distributed in a ring at the bottom edge of the hollow I-beam.

[0012] Further optimization: The water quality detection module includes a COD turbidity sensor, a residual chlorine sensor, a TDS salinity sensor, and an ammonia nitrogen sensor that are fixedly and continuously installed on the end plate; the detection ends of the COD turbidity sensor, residual chlorine sensor, TDS salinity sensor, and ammonia nitrogen sensor are arranged in a ring at intervals and are all located outside the liquid collection and reuse pipe assembly.

[0013] Further optimization: The liquid collection and reuse pipe assembly includes a hollow main pipe fixedly installed at the center of the bottom end of the end plate. Multiple U-shaped surrounding pipes are fixedly installed in a ring at equal intervals on the outer wall of the hollow main pipe. Several liquid outlet holes are opened on the pipe wall of the U-shaped surrounding pipes.

[0014] Further optimization: An electromagnetic switch valve is also installed at the bottom of the hollow main pipe. The electromagnetic switch valve controls whether the hollow main pipe and the inner sample tank are connected. The input end of the electromagnetic switch valve is electrically connected to the output end of the touch panel.

[0015] The present invention also provides a rapid detection method for livestock water, using the above-mentioned rapid detection device for livestock water, comprising the following steps: S101: Transport the testing device to the designated sampling point, check whether the clean water stored in the water supply module is sufficient, and confirm that the power connection of the device is stable. S102: To collect water samples, the staff first connects the external sampling hose to the inlet of the sample liquid inlet module and places the other end of the sampling hose into the water source to be tested. Then, the vortex magnetic pump is started and the sample liquid inlet module is turned on. The water sample is pumped into the collection and reuse tube assembly and then injected into the inner collection chamber until the preset standard volume required for testing is reached. Then the vortex magnetic pump is turned off. S103: After the liquid is injected, the water sample in the inner sample collection tank comes into contact with the various sensors of the water quality detection module. The water quality detection module measures the chemical indicators of the water sample. The real-time electrical signal generated by the measurement is collected and converted into a digital signal. The processed result is dynamically displayed on the touch panel. S104: When cleaning the inside of the device, first turn on the vortex magnetic pump again and keep the water supply module in the normally open state while the sample liquid inlet module is in the normally closed state. The water in the water supply module flows through the liquid collection and reuse tube assembly under pressure. The liquid collection and reuse tube assembly sprays the water out at a certain flow rate and angle to thoroughly flush the inner wall of the inner sample collection chamber and the surface of all sensors in the water quality detection module that have come into contact with the water sample, so as to thoroughly flush away the residual sample liquid. All the waste liquid generated by rinsing is collected at the bottom of the inner sample collection chamber and then completely discharged to the external waste liquid collection point by the liquid discharge solenoid valve which is kept in the open state.

[0016] The present invention, by adopting the above technical solution, has at least the following beneficial effects: 1. In this invention, a vortex magnetic pump and a sample inlet module allow water sample solution to enter the collection and reuse tube assembly and the inner sample collection chamber. After the inlet is complete, the water quality detection module performs sample solution testing. The collected numerical signals are transmitted to the touch panel for display. During device cleaning and maintenance, the vortex magnetic pump and the purified water supply module allow purified water to enter the collection and reuse tube assembly. The collection and reuse tube assembly sprays purified water to rinse the inner sample collection chamber and various sensors in the water quality detection module. The waste liquid after rinsing is discharged through the discharge solenoid valve. This invention solves the problems of low efficiency and incomplete cleaning in traditional manual cleaning. This device allows the subsequent cleaning operations of purified water injection, internal rinsing, and waste liquid discharge to be completed automatically, thereby minimizing the preparation time between two tests and allowing staff to manage more water level monitoring points at the same time, thus improving testing efficiency.

[0017] 2. The various sensors in the water quality detection module of this invention, equipped with ion-selective electrodes or optical probes, are exposed to complex aquaculture water samples for extended periods. Their surfaces are prone to scaling or organic matter buildup, leading to signal drift and sluggish response. The vortex magnetic pump, water purification supply module, and liquid collection and reuse pipe assembly provide regular, gentle, and thorough automatic flushing, effectively removing these deposits and attachments and preventing irreversible damage to the sensors caused by long-term accumulation and solidification of contaminants. Finally, the cleaning is performed through a closed pipeline, and the waste liquid is discharged to a designated collection point via a discharge solenoid valve. The entire maintenance process requires no complex disassembly, brushing, or assembly, making daily maintenance of the equipment much easier. Attached Figure Description

Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 4 As shown, a rapid testing device for livestock water includes a cylindrical shell 1. A base 3 is fixedly installed at the bottom end of the cylindrical shell 1, and a protective shell 4 is fixedly installed at the top end of the cylindrical shell 1. An end plate 2 is fixedly installed at the opening at the top end of the cylindrical shell 1. An inner sample collection chamber 101 is installed at the bottom end of the end plate 2. A liquid discharge solenoid valve 102 is installed at the center of the lower end of the inner sample collection chamber 101. A vortex magnetic pump 8 is installed at the top end of the end plate 2. The inlet end of the vortex magnetic pump 8 is equipped with... The sample inlet module 7 is provided, and a purified water supply module 6 is installed on the outer wall of the cylindrical shell 1. The purified water supply module 6 is also connected to the inlet end of the vortex magnetic pump 8. The inner sample collection chamber 101 is equipped with a liquid collection and reuse tube assembly 5. A water quality detection module 11 is installed at the bottom end of the end plate 2. The water quality detection module 11 is located outside the liquid collection and reuse tube assembly 5. An outlet pipe 9 is installed at the outlet end of the vortex magnetic pump 8. The lower end of the outlet pipe 9 extends into the interior of the liquid collection and reuse tube assembly 5.

[0022] The top of the protective shell 4 is equipped with a touch panel 10. The control output terminal of the touch panel 10 is electrically connected to the control input terminal of the vortex magnetic pump 8, the water supply module 6, the sample liquid inlet module 7 and the liquid discharge solenoid valve 102, respectively. The input terminal of the touch panel 10 is electrically connected to the output terminal of the water quality detection module 11.

[0023] Several U-shaped seats are installed at equal intervals along the vertical direction on the outer wall of the inner sample collection chamber 101. Bolts for connecting with the U-shaped seats are installed on the outer wall of the cylindrical shell 1. The inner sample collection chamber 101 is fixedly installed inside the cylindrical shell 1 by the cooperation of the bolts and U-shaped seats, which facilitates assembly and installation.

[0024] In this embodiment, the outer wall of the protective shell 4 is provided with ventilation holes and windows for the vortex magnetic pump 8 to dissipate heat.

[0025] In this embodiment, the base 3 includes a hollow I-beam fixed to the bottom of the inner sample collection chamber 101 and a plurality of foot supports evenly distributed in a ring at the bottom edge of the hollow I-beam. The foot supports are placed stably on the ground.

[0026] With this design, the cylindrical shell 1, protective shell 4, and base 3 serve as the external structure, providing robust protection and ensuring the stability of the internal modules. The inner sample collection chamber 101 is used to collect water samples and temporarily store the water samples collected from the water source, ensuring that the water samples are not contaminated by the outside world before testing, and maintaining the representativeness and authenticity of the samples.

[0027] In this embodiment, the discharge solenoid valve 102 remains closed during sample injection or testing to ensure that the sample liquid does not leak; when it is necessary to drain the waste sample or clean the waste liquid, it opens instantly upon receiving a command from the touch panel 10, and the liquid is quickly and completely discharged by gravity, and then closes.

[0028] like Figure 5 and Figure 6 As shown, during the detection phase, the vortex magnetic pump 8 draws the water sample to be tested from the sample liquid inlet module 7, while during the cleaning phase, it draws cleaning water from the purified water supply module 6, thus completing the task of transporting the two liquids by changing the connection path.

[0029] The sample liquid inlet module 7 consists of a C-tube 701 and a first electromagnetic inlet valve 702. The C-tube 701 is installed on one side inside the protective shell 4, and one end of the C-tube 701 is connected to the inlet end of the vortex magnetic pump 8. The first electromagnetic inlet valve 702 is installed on the other end of the C-tube 701.

[0030] During the sampling phase, the No. 1 electromagnetic inlet valve 702 is in the normally open state. The vortex magnetic pump 8, the C-tube 701, and the No. 1 electromagnetic inlet valve 702 draw livestock water from the water source to be tested into the outlet pipe 9, the liquid collection and reuse pipe assembly 5, and the inner sample collection chamber 101 through the hose.

[0031] The water supply module 6 includes a storage tank 601 fixedly installed on the outer wall of the cylindrical shell 1. A second electromagnetic inlet valve 603 is installed at the middle position of the C-shaped pipe 701. An L-shaped inlet pipe 602 is installed at the lower end of the second electromagnetic inlet valve 603. One end of the L-shaped inlet pipe 602 passes through the outside of the protective shell 4 and extends into the inside of the storage tank 601.

[0032] In this embodiment, the storage tank 601 may be filled with deionized water or distilled water.

[0033] During the cleaning and maintenance phase, the No. 1 electromagnetic inlet valve 702 is normally closed, while the No. 2 electromagnetic inlet valve 603 is normally open. The clean water in the storage tank 601 can be collected into the C-shaped pipe 701 through the L-shaped inlet pipe 602 and the No. 2 electromagnetic inlet valve 603, and then sent to the collection and reuse pipe assembly 5 and the inner sample collection tank 101 by the vortex magnetic pump 8 and the outlet pipe 9. This flushes the water quality detection module 11 and the inner sample collection tank 101, effectively dissolving and removing residual salts, organic matter or reaction products, ensuring no cross-contamination.

[0034] In this embodiment, the end of the L-shaped inlet pipe 602 away from the second electromagnetic inlet valve 603 passes through the upper end of the storage tank 601 and extends to the bottom surface of the storage tank 601, so that the lower end of the L-shaped inlet pipe 602 is arranged below the liquid surface, which facilitates the suction of clean water in the storage tank 601.

[0035] like Figure 7 and Figure 8 As shown, the water quality detection module 11 includes a COD turbidity sensor 1101, a residual chlorine sensor 1102, a TDS salinity sensor 1103, and an ammonia nitrogen sensor 1104, which are fixedly installed on the end plate 2. The detection ends of the COD turbidity sensor 1101, the residual chlorine sensor 1102, the TDS salinity sensor 1103, and the ammonia nitrogen sensor 1104 are arranged in a ring at intervals and are all located outside the liquid collection and reuse pipe assembly 5.

[0036] The COD turbidity sensor 1101 is used to quickly assess the degree of organic pollution and physical cleanliness of water bodies. A high COD value may mean that the water source is polluted by feces, feed residue or other organic waste. These organic substances not only consume dissolved oxygen in the water and promote the reproduction of pathogenic microorganisms, but may also directly affect the intestinal health of animals.

[0037] The 1102 residual chlorine sensor monitors the residual chlorine level in water, allowing farms to ensure the effectiveness of water disinfection while avoiding potential risks to animal health due to excessive chlorine levels.

[0038] The TDS salinity sensor 1103 measures the total amount of dissolved salt in water; while the ammonia nitrogen sensor 1104 monitors the ammonia nitrogen level.

[0039] The liquid collection and reuse pipe assembly 5 includes a hollow main pipe 501 fixedly installed at the center of the bottom end of the end plate 2. Multiple U-shaped surrounding pipes 502 are fixedly installed in a ring at equal intervals on the outer wall of the hollow main pipe 501. Several liquid outlet holes 503 are opened on the pipe wall of the U-shaped surrounding pipes 502.

[0040] After the purified water is fed into the hollow main pipe 501 by the vortex magnetic pump 8 and the outlet pipe 9, the purified water enters into several U-shaped surrounding pipes 502 that are distributed in a ring-shaped radial pattern, and is sprayed out from each outlet hole 503 on the pipe body, thereby performing a comprehensive and mechanical flushing of all sensor surfaces that have come into contact with the water sample, improving the cleaning effect.

[0041] The bottom of the hollow main pipe 501 is also equipped with an electromagnetic switch valve, which controls whether the hollow main pipe 501 and the inner sample collection chamber 101 are connected. The input end of the electromagnetic switch valve is electrically connected to the output end of the touch panel 10. The sample liquid or cleaning liquid in the hollow main pipe 501 can be discharged through the electromagnetic switch valve to reduce liquid retention.

[0042] like Figure 1-8 As shown: In this embodiment, the present invention also provides a rapid detection method for livestock water, using the above-mentioned rapid detection device for livestock water, including the following steps: S101: Transport the testing device to the designated sampling point, such as next to the drinking nipple or at the water tank inlet, then check whether the clean water stored in the water supply module 6 is sufficient and confirm that the power connection of the device is stable.

[0043] S102: When the vortex magnetic pump 8 is started on the touch panel 10 and water samples are collected, the staff connects the external sampling hose to the inlet of the sample liquid inlet module 7 and places the other end of the hose into the water source to be tested. The water sample is pumped into the liquid collection and reuse tube assembly 5 and injected into the inner sample collection chamber 101 until the preset standard volume required for testing is reached. At this time, the vortex magnetic pump 8 stops working.

[0044] S103: After the liquid is introduced, the water sample in the inner sample collection tank 101 comes into contact with each sensor of the water quality detection module 11. The water quality detection module 11 measures the chemical indicators of the water sample. The real-time electrical signal generated by the measurement is collected and converted into a digital signal. The processed result is dynamically displayed on the touch panel 10.

[0045] S104: When cleaning the inside of the device, the vortex magnetic pump 8 is turned on again via the touch panel 10, and the water supply module 6 is kept in the normally open state while the sample liquid inlet module 7 is kept in the normally closed state. The water in the water supply module 6 flows through the liquid collection and reuse tube assembly 5 under pressure. The liquid collection and reuse tube assembly 5 sprays the water at a certain flow rate and angle, which thoroughly flushes the inner wall of the inner sample collection chamber 101 and all sensor surfaces in the water quality detection module 11 that have come into contact with the water sample, so as to completely remove the residual sample liquid. All the waste liquid generated by rinsing is collected at the bottom of the inner sample collection chamber 101 and completely discharged to the external waste liquid collection point by the liquid discharge solenoid valve 102 which is kept in the open state.

[0046] After cleaning, all liquid passages and sensors inside the detection device are clean and ready for use. Staff can immediately proceed with the detection of the next water point or shut down the detection device.

[0047] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.

The liquid collection and reuse tube assembly (5) sprays the water at a certain flow rate and angle to thoroughly flush the inner wall of the inner sample collection chamber (101) and the surface of all sensors in the water quality detection module (11) that have been in contact with the water sample, so as to thoroughly flush the residual sample liquid. All the waste liquid generated by rinsing is collected at the bottom of the inner sample collection chamber (101) and then completely discharged to the external waste liquid collection point by the liquid discharge solenoid valve (102) which is kept in the open state.
