Description

Technical Field

[0001] This application belongs to the field of water quality analysis technology, specifically a sedimentation device for water quality analysis. Background Technology

[0002] Water quality analysis is the process of detecting and evaluating various physical, chemical, and biological properties of water. It mainly includes the analysis of inorganic matter, organic matter, microorganisms, and some physical indicators in the water. It aims to prevent various diseases caused by drinking or contact with contaminated water. For industries that rely on water resources, such as agriculture, fisheries, and industry, good water quality can improve production efficiency and product quality.

[0003] For example, patent CN216410844U discloses a sedimentation device for water quality analysis, including a base, support frames on both sides of the top of the base, a top plate fixedly connected to the top of the support frames, and a sedimentation tank at the top of the base. This sedimentation device for water quality analysis includes a filter plate, a first mounting block, a limiting groove, and a limiting block. Impurities in the water settle to the bottom of the sedimentation tank. The filter plate at the bottom of the sedimentation tank filters impurities, preventing them from clogging the outlet pipe during water discharge. When the filter plate rises, the limiting block slides within the limiting groove, limiting the filter plate and preventing it from swaying during ascent. This solves the problem of ineffective filter plate limiting, which leads to filter screen swaying and impurities falling into the sedimentation tank.

[0004] However, the device was not equipped with a component for adjusting the internal water suction height. Because water quality stratification exists in the vertical direction, the lack of a component to adjust the suction height prevented targeted water sampling at different water layers. Utility Model Content

[0005] The purpose of this application is to provide a sedimentation device for water quality analysis, in order to solve the problem that the aforementioned device does not have a component for adjusting the internal water suction height, and that the water quality stratifies in the vertical direction, making it impossible to collect targeted water samples from different water layers due to the lack of a component for adjusting the suction height.

[0006] The technical solution adopted in this application is as follows: it includes a platform, a support column is fixedly installed on the upper surface of the platform, a servo motor is fixedly installed on the upper surface of the support column, a lead screw is fixedly installed through the support column on the upper surface of the servo motor, a lower limit rod is fixedly installed on the lower surface of the support column, a connecting plate is fitted inside the lead screw and the lower limit rod, and a water suction port is fixedly installed inside the connecting plate.

[0007] By employing the above technical solution, a support column is fixedly installed on the upper surface of the platform. A servo motor is fixedly installed on the upper surface of the support column, and a lead screw is fixedly installed through the support column on the upper surface of the servo motor. A lower limit rod is fixedly installed on the lower surface of the support column. A connecting plate is installed in close contact with the inside of the lead screw and the lower limit rod. A water suction port is fixedly installed inside the connecting plate. The platform serves as the installation base for the water pumping component, providing a position for the installation of the water pumping component and the adjusting component. The support column provides support for the fixing of the adjusting component. The combination of the servo motor, lead screw, lower limit rod, and connecting plate allows the servo motor to act as the power source for changing the water suction height, providing power for the rotation of the lead screw. Driven by the servo motor, the lead screw rotates. The lower limit rod causes the connecting plate installed inside it to move in the direction defined by the lower limit rod, preventing the connecting plate from... Displacement occurs during vertical movement. During the rotation of the lead screw, the threaded engagement between the outer surface of the lead screw and the interior of the lower limit rod causes the connecting plate to move linearly along the axis of the lead screw. This, in turn, causes the water inlet fixedly installed inside the connecting plate to change its vertical position. When it is necessary to absorb water layers of different heights, the servo motor drives the lead screw to move the connecting plate and the water inlet on the outer surface of the lead screw up and down, enabling targeted water sample collection at different water layers. The water inlet serves as the suction port of the pumping component, used to absorb water at different heights when the connecting plate reaches different heights. By installing a component to adjust the water suction height inside the device, and considering the vertical stratification of water, targeted water sample collection at different water layers can be achieved by installing a component to adjust the height of the water inlet.

[0008] In a preferred embodiment, a water pump is fixedly installed on the upper surface of the platform, and a metal corrugated pipe is fixedly installed on the same inner side of the water inlet and the water pump.

[0009] By adopting the above technical solution, a water pump is fixedly installed on the upper surface of the platform, and a metal corrugated pipe is fixedly installed on the same inner side of the water inlet and the water pump. The water pump, as the main part of the water pumping assembly, provides the power source for water intake. Starting the water pump can draw water from inside the device into the analysis component for water quality analysis. The metal corrugated pipe can change its downward extension length during the up and down movement of the water inlet due to its foldability. The outer surface of the metal corrugated pipe includes a drag chain, which is used to regularly change the angle of the metal corrugated pipe inside the drag chain.

[0010] In a preferred embodiment, a limit bracket is fixedly installed on the upper surface of the connecting plate, and an upper limit rod is fixedly installed on the upper surface of the support column.

[0011] By adopting the above technical solution, a limiting bracket is fixedly installed on the upper surface of the connecting plate, and an upper limit rod is fixedly installed on the upper surface of the support column. The limiting bracket serves as the base point for angle changes and contains a column and an electric roller. The column supports the electric roller, and the electric roller ensures that the folding point of the metal corrugated pipe remains in a certain position. When the connecting plate rises, the electric roller of the limiting bracket rotates towards the water pump, allowing the metal corrugated pipe to rise vertically backward, enabling the water inlet to rise normally. When the connecting plate falls, the electric roller of the limiting bracket rotates towards the water inlet, extending the metal corrugated pipe forward, allowing the pipe to descend towards the water inlet and follow the water inlet to perform water suction. The outer surface of the upper limit rod is attached to the upper end of the limiting bracket, and the upper limit rod can restrict the position of the upper end of the limiting bracket, preventing the upper end of the limiting bracket from shifting when the water inlet moves.

[0012] In a preferred embodiment, a sedimentation tank is fixedly installed on the outer surface of the platform, and multiple tie rods are fixedly installed inside the sedimentation tank.

[0013] By adopting the above technical solution, a sedimentation tank is fixedly installed on the outer surface of the platform, and multiple tie rods are fixedly installed inside the sedimentation tank. After the water sample enters the sedimentation device, the suspended solid particles in the water will gradually settle to the bottom of the sedimentation tank under the action of gravity. The tie rods are used to enhance the structural strength of the sedimentation tank, which can extend the service life of the sedimentation tank, reduce the number of repairs and reconstructions caused by structural damage, and reduce the long-term operating cost of the device.

[0015] By adopting the above technical solution, a ladder is fixedly installed on the outer surface of the sedimentation tank, and an inspection port is opened on the outer surface of the ladder. The ladder provides a safe and convenient passage for workers to enter the sedimentation tank for maintenance and repair. The inspection port contains an inspection port body, a cover plate, rubber strips, and bolts. When the sedimentation tank is in normal use, the cover plate of the inspection port is fixed to the outer surface of the inspection port body with bolts. After removing the bolts, the cover plate can be removed, which makes it convenient for workers to clean the sludge inside the sedimentation tank. After cleaning, the cover plate is installed on the outer surface of the inspection port body with bolts. The sealing ring is fixed together with the inspection port body and fits together after the cover plate is installed to prevent water in the sedimentation collection tank 1 from leaking out of the inspection port.

[0016] In a preferred embodiment, an inlet pipe is fixedly installed on the left outer surface of the sedimentation tank, and a butterfly valve is fixedly installed on the right side of the lower surface of the sedimentation tank.

[0017] By adopting the above technical solution, an inlet pipe is fixedly installed on the left outer surface of the sedimentation tank, and a butterfly valve is fixedly installed on the right side of the lower surface of the sedimentation tank. The inlet pipe is made of metal and is used to introduce the water quality to be analyzed from the outside into the sedimentation tank. The outer surface of the inlet pipe includes a flow meter and an electric valve. The flow meter can measure the flow rate of the runoff in the inlet pipe in real time and accurately, providing accurate inlet flow rate data. The electric valve can control the flow rate of the runoff in the inlet pipe according to the set parameters or external signals. By adjusting the opening of the electric valve, the flow rate and flow size of the water entering the sedimentation tank can be accurately controlled. The butterfly valve can accurately control the discharge of water inside the sedimentation tank. By opening or closing the butterfly valve and adjusting the opening of the butterfly valve, the flow rate and speed of the drainage can be controlled.

The operating parameters of the device can be set and adjusted on the control box. The upper surface of the water quality analysis tank and the water pump are fixedly installed together through a management device. As the main part of the analysis component, the water quality analysis tank is used to analyze the water quality pumped by the water pump to confirm the water quality status.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, when the lead screw rotates, the connecting plate will move linearly along the axis of the lead screw, thereby causing the water inlet fixedly installed inside the connecting plate to change its vertical position. When it is necessary to absorb water layers of different heights, the servo motor drives the lead screw to move the connecting plate and the water inlet on the outer surface of the lead screw up and down, so as to achieve targeted water sample collection at different water layers. The water inlet serves as the water inlet of the pumping component, used to absorb water at different heights when the connecting plate reaches different heights.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figures 1-4The system includes platform 1, which serves as the mounting base for the pumping assembly and provides a position for the installation of the pumping and regulating assemblies. Support column 2 provides support for fixing the regulating assemblies. It employs a combination of servo motor 3, lead screw 4, lower limit rod 5, and connecting plate 6. Servo motor 3 provides the power source for changing the suction height, powering the rotation of lead screw 4. Driven by servo motor 3, lead screw 4 rotates. Lower limit rod 5 causes the connecting plate 6, installed inside it, to move in the direction defined by lower limit rod 5, preventing displacement of the connecting plate 6 during vertical movement. During the rotation of lead screw 4, the threads between the outer surface of lead screw 4 and the inside of lower limit rod 5 engage, ensuring proper rotation. The connecting plate 6 will move linearly along the axis of the lead screw 4, thereby changing the vertical height of the connecting plate 6 and the suction port 7 fixedly installed inside it. When it is necessary to absorb water layers of different heights, the servo motor 3 drives the lead screw 4 to move the connecting plate 6 and the suction port 7 on the outer surface of the lead screw 4 up and down, so as to collect targeted water samples at different water layers. The suction port 7 serves as the suction port of the pumping component, used to absorb water at different heights when the connecting plate 6 reaches different heights. By installing a component to adjust the suction height inside the device, since there is water quality stratification in the vertical direction, targeted water sample collection can be carried out at different water layers by installing a component to adjust the suction port height.

Starting the water pump 8 will draw water from inside the device into the analysis component for water quality analysis. The metal bellows 9 can change its downward extension length during the up-and-down movement of the water inlet 7 due to its foldability. The outer surface of the metal bellows 9 includes a drag chain, which is used to regularly change the angle of the metal bellows 9 inside the drag chain.

[0033] Reference Figure 2 and Figure 3 The limiting bracket 10 serves as the base point for angle changes. It contains a column and an electric roller. The column supports the electric roller, which ensures that the folding point of the metal corrugated pipe 9 remains in a certain position. When the connecting plate 6 rises, the electric roller of the limiting bracket 10 rotates towards the water pump 8, allowing the metal corrugated pipe 9 to rise vertically backward, enabling the suction port 7 to rise normally. When the connecting plate 6 falls, the electric roller of the limiting bracket 10 rotates towards the suction port 7, extending the metal corrugated pipe 9 forward, allowing the pipe to descend towards the suction port 7 and follow it to perform water suction. The outer surface of the upper limit rod 11 is attached to the upper end of the limiting bracket 10, which restricts the position of the upper end of the limiting bracket 10, preventing the upper end of the limiting bracket 10 from shifting when the suction port 7 moves.

The tie rod 13 is used to enhance the structural strength of the sedimentation tank 12, so that it can extend the service life of the sedimentation tank 12, reduce the number of repairs and reconstructions caused by structural damage, and reduce the long-term operating cost of the device.

[0035] Reference Figure 1 The ladder 14 provides a safe and convenient passage for staff to enter the sedimentation tank 12 for maintenance and repair. The inspection port 15 contains the inspection port body, cover plate, rubber strip and bolts. When the sedimentation tank 12 is in normal use, the cover plate of the inspection port 15 is fixed to the outer surface of the inspection port body with bolts. After removing the bolts, the cover plate can be removed, which makes it convenient for staff to clean the sludge inside the sedimentation tank 12. After cleaning, the cover plate can be installed on the outer surface of the inspection port body with bolts. The sealing ring is fixed together with the inspection port body and fits with it after the cover plate is installed to prevent water in the sedimentation collection tank 1 from leaking from the inspection port 15.

[0036] Reference Figure 1 and Figure 2 The inlet pipe 16 is made of metal and is used to introduce the water quality to be analyzed into the sedimentation tank 12. The outer surface of the inlet pipe 16 includes a flow meter and an electric valve. The flow meter can measure the flow rate of the runoff in the inlet pipe 16 in real time and accurately, providing accurate inlet flow rate data. The electric valve can control the flow rate of the runoff in the inlet pipe 16 according to the set parameters or external signals. By adjusting the opening of the electric valve, the flow rate and flow size of the water entering the sedimentation tank 12 can be precisely controlled. The butterfly valve 17 can accurately control the discharge of water inside the sedimentation tank 12. By opening or closing the butterfly valve 17 and adjusting the opening of the butterfly valve 17, the flow rate and speed of the discharge can be controlled.

The microprocessor is used to control the commands issued by the device. The display screen and indicator lights can display the operating status and related parameters of the device. The operating parameters of the device can be set and adjusted on the control box 21. The upper surface of the water quality analysis tank 22 is fixedly installed with the water pump 8 through a management device. As the main part of the analysis component, the water quality analysis tank 22 is used to analyze the water quality pumped by the water pump 8 to confirm the water quality status. Opening the gate valve 23 can discharge the water that has been analyzed inside the water quality analysis tank 22.

[0039] The implementation principle of an embodiment of a sedimentation device for water quality analysis in this application is as follows: Platform 1 serves as the installation foundation for the pumping component, providing a position for the installation of the pumping component and the regulating component. Support column 2 provides support for fixing the regulating component. A combination of servo motor 3, lead screw 4, lower limit rod 5, and connecting plate 6 is used. Servo motor 3 serves as the power source for driving the change of the suction height position, providing power for the rotation of lead screw 4. Driven by servo motor 3, lead screw 4 rotates. Lower limit rod 5 causes the connecting plate 6 installed inside it to move in the direction defined by lower limit rod 5, preventing displacement of connecting plate 6 during vertical movement. During the rotation of lead screw 4, the threads between the outer surface of lead screw 4 and the inside of lower limit rod 5... When the lead screw 4 rotates, the connecting plate 6 will move linearly along the axis of the lead screw 4, thereby changing the vertical position of the connecting plate 6 and the suction port 7 fixedly installed inside it. When it is necessary to absorb water layers of different heights, the servo motor 3 drives the lead screw 4 to move the connecting plate 6 and the suction port 7 on the outer surface of the lead screw 4 up and down, so as to collect targeted water samples at different water layers. The suction port 7 serves as the suction port of the pumping component, used to absorb water at different heights when the connecting plate 6 reaches different heights. By installing a component for adjusting the internal suction height of the device, since there is water quality stratification in the vertical direction, targeted water sample collection can be carried out at different water layers by installing a component for adjusting the suction port height.
