Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Referring to Figures 1-4 , the present invention provides a field water quality detection system, including:

[0037] Chassis 1, a support assembly and a moving assembly are installed at the bottom of the chassis 1;

[0038] Recovery bin 2, the recovery bin 2 is fixedly connected to the top of the chassis 1;

[0039] Mounting frame 3, the mounting frame 3 is fixedly connected to the top of the recovery bin 2;

[0040] Lifting frame 4, the lifting frame 4 is vertically slidably connected to the mounting frame 3, and a lifting component is installed on the mounting frame 3, and the lifting component is used to control the lifting of the lifting frame 4;

[0041] Placement shaft 5, the placement shaft 5 is rotatably connected to the lifting frame 4, and a flipping and dumping component is installed on the lifting frame 4, and the flipping and dumping component is used to control the rotation of the placement shaft 5. Two groups of positioning components are symmetrically installed on the placement shaft 5, and the storage box 6 is fixed to the placement shaft 5 through the positioning components;

[0042] Detection system, the detection system includes a detection probe and a host computer 7. A support frame 19 is fixedly connected to the top end of the mounting frame 3. The detection probe is installed on the support frame 19 and is correspondingly arranged with the storage box 6. The host computer 7 is connected to the detection probe;

[0043] Water sampling mechanism, the water sampling mechanism is installed on the side wall of the recovery bin 2, the output end of the water sampling mechanism is connected to the storage box 6, and the water sampling end of the water sampling mechanism extends into the water source;

[0044] Among them, a discharge port is opened at the bottom of the recovery bin 2, and the discharge port is connected to the waste water discharge component.

[0045] When the present invention is in operation, the operator moves the entire field water quality detection system to the vicinity of the target field water source by means of the moving components at the bottom of the chassis 1. During the moving process, it is necessary to pay attention to avoiding obstacles to ensure the safe arrival of the system. After reaching the appropriate position, adjust the support components to make them firmly contact the ground, providing stable support for the system to prevent the detection accuracy and equipment safety from being affected by shaking or tilting during subsequent operations. Conduct a comprehensive inspection of each component of the system to ensure that the lifting component, the tilting component, the positioning component, the water sampling mechanism, the detection system, and the wastewater discharge component are all in normal working conditions. If any problems are found, perform debugging or maintenance in a timely manner. Insert the water sampling end of the water sampling mechanism into the water source to ensure that the water sampling end can smoothly extract water samples, while avoiding affecting the water sampling effect due to blockage by debris. The operator starts the water sampling mechanism, and the water sampling mechanism extracts the water samples in the water source through the power device and transports them to the storage box 6 through the output end of the water sampling mechanism. During the water sampling process, the water sampling volume can be controlled according to actual needs. For example, set the water sampling volume through the host computer 7 or stop the water sampling by observing the water level scale in the storage box 6. According to the detection requirements, the operator controls the lifting component to make the lifting frame 4 slide vertically on the mounting frame 3, thereby adjusting the relative position between the support frame 19 and the storage box 6 to ensure that the detection probe can accurately extend into the water sample in the storage box 6. For example, if it is necessary to detect the water quality at different depth positions, the height of the lifting frame 4 can be adjusted multiple times to enable the detection probe to collect data at different depths. When the detection probe is accurately immersed in the water sample, the detection probe starts to work and detects various water quality indicators of the water sample, such as pH value, dissolved oxygen (DO), conductivity, turbidity, heavy metal content, organic pollutant concentration, etc. The detection probe converts the collected physical or chemical signals into electrical signals and transmits them to the host computer 7. After receiving the electrical signals from the detection probe, the host computer 7 analyzes and converts the signals through the built-in data processing software, converts the electrical signals into specific water quality index values, and displays them on the display screen of the host computer 7 in real time, facilitating the operator to view the detection progress and preliminary results at any time. The host computer 7 further analyzes the received water quality data, such as calculating statistical parameters such as the average value and standard deviation of each index, and judging whether the water quality meets the relevant standards. At the same time, the detection data is stored in the local storage device or cloud server of the host computer 7 for subsequent query, comparison, and further research. According to the preset templates and rules, the host computer 7 automatically generates a water quality detection report, which includes information such as detection time, location, various water quality index values, whether it meets the standards, and detection personnel. The report can be saved in the form of an electronic document or printed out by a printer. After the detection is completed, the operator starts the tilting component, controls the rotation of the placement shaft 5, and then drives the storage box 6 to tilt, pouring the tested water sample (wastewater) in the storage box 6 into the wastewater discharge component through the discharge port at the bottom of the recovery box 2. The wastewater discharge component guides the wastewater to a designated wastewater collection container or treatment area to avoid polluting the field environment. If another detection is to be carried out, after pouring the wastewater,The storage box 6 and the detection probe can be rinsed with clean water to remove the residual water samples and impurities, preventing interference with the next test result. The wastewater after rinsing is also discharged through the discharge port and the wastewater discharge component. The operator adjusts the lifting frame 4 back to the initial height position through the lifting component, ensuring that the support frame 19 and the detection probe are at appropriate heights, facilitating the next water sampling and detection operations. At the same time, check whether the positioning component is firm to ensure the stable fixing state of the storage box 6 on the placement shaft 5. After completing all detection work, sequentially turn off the related equipment such as the water sampling mechanism, the detection system, the lifting component, and the flipping and pouring component, tidy up and clean the system, and adjust the moving component and the support component to a state convenient for transportation to prepare for the next field water quality detection.

[0046] In a further optimized solution, the lifting component includes a lifting motor 8 and a transmission 9. Both the lifting motor 8 and the transmission 9 are fixedly connected to the back of the mounting frame 3. The output shaft of the lifting motor 8 is connected to the input shaft of the transmission 9. A lifting screw 10 is vertically rotatably connected to the mounting frame 3. The bottom end of the lifting screw 10 is connected to the output shaft of the transmission 9. A connecting arm 11 is fixedly connected to the lifting frame 4. An internally threaded sleeve 12 is threadedly connected to the lifting screw 10, and a fixed connection is provided between the internally threaded sleeve 12 and the connecting arm 11.

[0047] When it is necessary to adjust the relative height between the detection probe and the water sample (such as detecting water quality at different depths or adapting to different liquid levels), the operator starts the lifting motor 8. The lifting motor 8 starts to operate, and its output shaft drives the input shaft of the transmission 9 connected thereto to rotate.

[0048] The transmission 9 adjusts the rotational speed and torque output by the lifting motor 8 to meet the working requirements of the lifting screw 10. The power after speed change is transmitted from the output shaft of the transmission 9 to the bottom end of the lifting screw 10, causing the lifting screw 10 to start rotating.

[0049] Since the connecting arm 11 on the lifting frame 4 is threadedly connected to the lifting screw 10 through the internally threaded sleeve 12, when the lifting screw 10 rotates, the internally threaded sleeve 12 moves axially along the lifting screw 10 under the action of the thread, thereby driving the connecting arm 11 and the lifting frame 4 to slide vertically on the mounting frame 3, adjusting the height of the storage box 6.

[0050] In a further optimized solution, the flipping and pouring component includes a mounting seat 13 fixedly connected to the lifting frame 4. A rotation control motor 14 is fixedly connected to the mounting seat 13. The output shaft of the rotation control motor 14 is fixedly connected to a connecting shaft 15. One end of the placement shaft 5 passes through the lifting frame 4 and is fixedly connected to a driven bevel gear 16. One end of the connecting shaft 15 is fixedly connected to a driving bevel gear, and meshing is provided between the driving bevel gear and the driven bevel gear 16.

[0051] After the water quality test is completed, when the water sample in the storage box 6 needs to be dumped into the discharge port of the recovery box 2, the operator starts the rotation control motor 14. The output shaft of the rotation control motor 14 starts to rotate, driving the connecting shaft 15 fixedly connected thereto to rotate synchronously.

[0052] The driving bevel gear at one end of the connecting shaft 15 rotates accordingly. Since the driving bevel gear is meshed with the driven bevel gear 16 at one end of the placement shaft 5, the rotation of the driving bevel gear drives the driven bevel gear 16 to rotate, thereby causing the placement shaft 5 to rotate on the lifting frame 4.

[0053] The rotation of the placement shaft 5 drives the storage box 6 fixed thereon by the positioning component to flip together, pouring the water sample in the storage box 6 into the recovery box 2, and discharged to the wastewater discharge component through the discharge port at the bottom of the recovery box 2.

[0054] A further optimization scheme is that the positioning assembly includes a positioning frame 17, the bottom of the positioning frame 17 is fixedly connected with a sliding sleeve 18, the sliding sleeve 18 is slidably connected to the placement shaft 5, a threaded hole is opened on the side of the sliding sleeve 18, a positioning bolt is threadedly connected in the threaded hole, and the positioning bolt is abutted against the placement shaft 5.

[0055] When installing the storage box 6, the sliding sleeve 18 at the bottom of the positioning frame 17 is sleeved on the placement shaft 5, and the positioning frame 17 is axially slid along the placement shaft 5 to a suitable position, so that the storage box 6 can be accurately placed at the predetermined position.

[0056] By rotating the positioning bolt on the side of the sleeve 18, the end of the positioning bolt is gradually pressed against the placement shaft 5, and the friction between the positioning bolt and the placement shaft 5 is used to fix the sleeve 18 on the placement shaft 5, so that the storage box 6 is stably fixed on the placement shaft 5 to prevent the storage box 6 from moving during the detection or flipping process.

[0057] When the position of the storage box 6 needs to be adjusted or the storage box 6 needs to be removed, the positioning bolt only needs to be rotated in the opposite direction to disengage the positioning bolt from the placement shaft 5 , and then the sliding sleeve 18 can be slid to reposition or remove the storage box 6 .

[0058] A further optimization scheme is that several groups of support components are installed at the bottom of the base frame 1, and the support components include a support screw 20, which is threadedly connected to the bottom of the base frame 1, and the bottom end of the support screw 20 is fixedly connected to a support seat 21.

[0059] When the system needs to be moved, the support screw 20 is in a relatively retracted state, and the support seat 21 leaves the ground, so that the universal wheel 22 can roll freely, making it convenient for the operator to move the system to different testing locations.

[0060] After arriving at the detection location, the operator rotates the support screw 20. Since the support screw 20 is threadedly connected to the chassis 1, rotating the support screw 20 will cause the support screw 20 to move downward relative to the chassis 1 until the support seat 21 is in close contact with the ground, providing stable support for the entire system, preventing the system from shaking or displacing during the detection process, and ensuring the accuracy of the detection results.

[0061] For a further optimized solution, the water collection mechanism includes a collection box 23, which is fixed on the side wall of the recovery box 2. One side of the collection box 23 is provided with a collection pipe 24, one end of the collection pipe 24 extends into the water source, one side of the collection box 23 is provided with a switching box 25, and two groups of shunt pipes 26 are installed on the side of the switching box 25 away from the collection box 23. The shunt pipes 26 are respectively connected to the storage box 6. A filter screen is arranged in the collection pipe 24, and two groups of water passing holes are formed in the side wall of the switching box 25. Both groups of water passing holes are communicated with the collection box 23 and are respectively arranged in one-to-one correspondence with the shunt pipes 26. A switching component is installed in the switching box 25; a backwashing component is installed on the collection box 23;

[0062] Among them, a collection water pump is installed on the collection pipe 24.

[0063] For a further optimized solution, the switching component includes a cylinder 27 fixedly connected horizontally to the top of the switching box 25. A slot is formed in the side of the switching box 25, and a switching plate 28 is slidably connected in the slot. A group of switching holes are formed in the switching plate 28, and the switching holes are arranged corresponding to the collection pipe 24 near the slot opening.

[0064] For a further optimized solution, a backwashing component is installed on the collection box 23. The backwashing component includes a backwashing water tank and a backwashing pump. The backwashing pump is installed at the water outlet of the backwashing water tank, and the output end of the backwashing pump is installed with a backwashing pipe, and the backwashing pipe is communicated with the side wall of the collection pipe 24.

[0065] The operator starts the collection water pump, and the collection water pump starts to work, pumping the water in the water source into the collection box 23 through the collection pipe 24. The filter screen arranged in the collection pipe 24 can preliminarily filter the water entering the collection box 23, intercepting larger particle impurities in the water, preventing the impurities from entering the subsequent pipelines and the storage box 6 and affecting the detection results or damaging the equipment.

[0066] In the initial state, the switching holes on the switching plate 28 of the switching component correspond to the collection pipe 24 near the slot opening. The water in the collection box 23 flows into the switching box 25 through the water passing hole corresponding to the collection pipe 24 on the side wall of the switching box 25, and then enters the storage box 6 through the shunt pipe corresponding to the water passing hole, completing the water collection process.

[0067] When the collection pipe 24 or the filter screen is blocked due to long-term use, the operator starts the backwashing pump. The backwashing pump extracts water from the backwashing water tank and injects the water into the collection pipe 24 in the reverse direction through the backwashing pipe.

[0068] The backflush water forms a reverse water flow in the collection pipe 24, flushing the filter screen and the inner wall of the collection pipe 24, washing away the impurities blocked on the filter screen and the dirt in the collection pipe 24, restoring the collection pipe 24 and the filter screen to be unobstructed, and ensuring the normal operation of the water collection mechanism.

[0069] When it is necessary to change the water flow direction (such as switching to another storage box 6 for detection or cleaning operations), the operator controls the telescopic movement of the piston rod of the cylinder 27. The telescopic movement of the piston rod of the cylinder 27 drives the switching plate 28 to slide horizontally in the slot on the side of the switching box 25.

[0070] Through the sliding of the switching plate 28, the switching holes on the switching plate 28 correspond to different water passing holes, thereby changing the outflow path of the water in the collection box 23, enabling the water to flow into different shunt pipes 26, and then entering the corresponding storage box 6 or being used for other operations.

[0071] In a further optimized solution, several groups of moving components are installed at the bottom of the chassis 1. The moving components include universal wheels 22, which are fixed to the bottom of the chassis 1, and a braking component is installed on the universal wheels 22.

[0072] When it is necessary to move the field water quality detection system, the operator pushes the system, and the universal wheels 22 at the bottom of the chassis 1 roll on the ground. Since the universal wheels 22 can rotate 360 degrees, the moving direction of the system can be conveniently changed, enabling the system to move flexibly between different terrains and sites.

[0073] After the system reaches the detection location, the operator steps on the braking component on the universal wheels 22. The braking component is in close contact with the wheel body of the universal wheels 22, generating frictional force to stop the universal wheels 22 from rotating, thereby fixing the system at the current position, preventing the system from moving during the detection process, and ensuring the stable progress of the detection work.

[0075] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention.
