Description

Technical Field

[0001] This invention belongs to the field of automatic water sampling technology, specifically an automatic water sampling and separation device. Background Technology

[0002] Water sampling is a fundamental task in water environment management. Its core purpose is to obtain representative water samples to scientifically assess the physical, chemical, and biological characteristics of water bodies. Main objectives include: pollution monitoring, detecting concentrations of pollutants such as heavy metals, organic matter, and nutrients, identifying pollution sources and their diffusion trends. Currently, water sampling is generally conducted using automated water sampling equipment. By connecting the sampling tube of this equipment to water pipes or sewage pipes in rivers, the automated water sampling equipment can collect water samples intermittently around the clock, establishing a database to reveal the spatiotemporal patterns of water quality changes and support watershed management decisions.

[0003] Existing automatic water sampling equipment mainly includes a sampling unit, a distribution unit, a control unit, and an auxiliary unit. The sampling unit includes a pump and pipeline, the distribution unit includes a sampling bottle turntable / distribution arm and sampling bottles, the control unit includes a main board, a button panel, and a clock module, and the auxiliary unit includes a refrigeration system, a chassis, and a communication module. In use, the control unit controls the pump to draw water from the river or sewage pipes, then introduces the water into the sampling bottles, and distributes the water equally into multiple sampling bottles through the turntable / distribution arm. Finally, the refrigeration system refrigerates and preserves the sampling bottles to prevent the water inside from becoming moldy.

[0004] In the above-mentioned scheme, the extracted water sample can be equally divided into multiple sampling bottles by a turntable / distribution arm. During use, multiple sampling bottles need to be placed on the turntable one by one. After the sampling bottles are filled with water sample, they need to be removed from the turntable one by one, which makes it cumbersome for staff to handle the sampling bottles. The distribution arm is formed by two sets of ball screw structures. The water outlet pipe of the sampling unit is installed on the distribution arm. The distribution arm can drive the water outlet pipe to switch back and forth between the X and Y axes to fill the arranged sampling bottles. During this process, the water outlet pipe needs to bend due to frequent switching of multi-axis movement, which leads to the rapid aging of the water outlet pipe. Secondly, the length of the water outlet pipe must be able to cover the arranged sampling bottles, resulting in a long water outlet pipe. Due to the small internal space of the device, it is not conducive to the staff to lay the water outlet pipe. Therefore, the present invention provides an automatic water quality sampling and distributing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The automatic water sampling and sampling device of the present invention includes a cabinet, a pump suction host is provided on the cabinet, an inlet pipe and an outlet pipe are connected to the pump suction host, the lower end of the outlet pipe is installed on a ball screw mechanism, a sampling plate is provided below the ball screw mechanism, several sets of sample bottles are arranged below the sampling plate, the several sets of sample bottles are placed on a tray, the tray is movably installed in the cabinet, a cooling mechanism is provided below the tray, several sets of flow channels are opened on the sampling plate, and a liquid drop hole is opened at one end of the flow channel, the liquid drop hole is directly opposite the bottle mouth of the sample bottle.

[0007] The coordinated design of the sample plate, ball screw mechanism, and tray allows the water outlet pipe to be sampled simply by moving along the X-axis, reducing the bending degree of the water outlet pipe and extending its service life.

[0008] Preferably, a sealing mechanism is provided at the bottom of the sample plate. The sealing mechanism includes two sets of first guide rails, which are fixedly installed at the bottom of the sample plate. A movable plate is slidably connected to the two sets of first guide rails. A cylinder is fixedly installed on the outside of the cabinet to drive the movable plate. Two sets of sealing plates are symmetrically distributed on both sides of the movable plate. The sealing plates are slidably installed on the bottom of the sample plate. The extensions on both sides of the movable plate are located in the two sets of sealing plates respectively. An oblique groove is opened on the sealing plate. A pin is provided on the extension. The end of the pin is located in the oblique groove. One end of the water inlet pipe is connected to the liquid inlet pipe. The liquid inlet pipe includes a first electric three-way ball valve. The outlet of the first electric three-way ball valve is connected to the water inlet pipe. The two sets of water inlet ends on the first electric three-way ball valve are respectively connected to pipe one and pipe two. One end of pipe two is connected to the outlet of the second electric three-way ball valve. The two sets of water inlet ends on the second electric three-way ball valve are respectively connected to pipe three and pipe four. By coordinating the inlet pipeline with the sealing mechanism, automatic cleaning of the flow channel is achieved, thereby improving the automation rate of the device.

[0009] Preferably, the sample dividing plate is provided with a series connection mechanism, which includes a series connection tube, which is fixedly installed in the sample dividing plate, several sets of series connection ports are opened at equal intervals on the series connection tube, and the several sets of series connection ports are respectively aligned with several sets of flow channels, a cover plate is installed on the series connection port, a lifting plate is movably installed below the series connection tube, several sets of connectors are arranged at equal intervals on the lifting plate, the upper end of the connectors is connected to the cover plate, a waste liquid pipe is fixedly connected to one end of the series connection tube, one end of the waste liquid pipe is connected to a water pump, four sets of guide posts are installed at the bottom of the series connection tube, four sets of through holes are opened on the lifting plate, the through holes are slidably connected to the guide posts, the inside of the series connection tube is hollow, and the inside of the series connection tube is connected to several sets of flow channels through several sets of series connection ports; When it is necessary to drain the liquid in the flow channel, the water pump is started. The water pump drains the liquid in the flow channel along with the connecting pipe through the waste liquid pipe, thereby realizing automatic cleaning of the waste liquid and improving the practicality of the device.

[0010] Preferably, the connector includes a connecting rod, which is movably inserted into the bottom of the connecting pipe, a horizontal plate fixedly connected to the upper end of the connecting rod, two sets of third guide rails symmetrically slidably installed on the horizontal plate, a cover plate fixedly connected to the upper end face of the third guide rail, a rotating rod rotatably installed inside the connecting rod, a gear installed at the upper end of the rotating rod, the gear meshing with a rack, a cover plate fixedly connected to the upper end face of the rack, a rectangular shaft movably inserted into the rotating rod, a worm gear installed at the lower end of the rectangular shaft, several sets of worm gears meshing with a worm, the worm rotatably installed inside the cabinet, and several sets of support plates equally spaced at the lower middle of the sample plate, with the lower end of the rectangular shaft rotatably connected to the support plates; The rectangular shaft drives the rotating rod and gear to rotate together. The rotating gear drives the rack and cover plate to move together. The cover plate drives the third guide rail to slide along the horizontal plate, which not only fully opens the top of the serial port, but also prevents the cover plate from being located directly below the water outlet pipe. This ensures the liquid flow rate while preventing liquid from splashing onto the sample plate.

[0011] The beneficial effects of this invention are as follows: 1. The coordinated design of the sample tray, ball screw mechanism, and tray allows the water outlet pipe to be sampled simply by moving along the X-axis, reducing the bending degree of the water outlet pipe and increasing its service life. Furthermore, the shorter length of the water outlet pipe facilitates its laying and installation by staff. Since all sample bottles are placed on the tray, pulling the tray allows all sample bottles to be removed from the cabinet at once, and then the next prepared tray can be placed into the cabinet, facilitating the handling of sample bottles by staff.

[0012] 2. When it is necessary to open the serial port, the lifting plate is driven upward by the cylinder. The lifting plate drives the connecting rod, along with the horizontal plate, the third guide rail, and the sealing plate, to move upward, thus opening the serial port. During this process, the rectangular shaft slides along the inner cavity of the rotating rod. Then, the worm gear is driven to rotate by the motor. The worm gear drives the corresponding rectangular shaft to rotate through several sets of worm wheels. The rectangular shaft drives the rotating rod and gear to rotate together. The rotating gear drives the rack and cover plate to move together. The cover plate drives the third guide rail to slide along the horizontal plate. This not only fully opens the top of the serial port, but also prevents the cover plate from being directly below the water outlet pipe, ensuring the liquid flow rate while avoiding liquid splashing onto the sample plate.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figure 1 and Figure 2 As shown in the embodiment of the present invention, an automatic water sampling and sorting device includes a cabinet 1, a pump suction host 2 is installed on the cabinet 1, an inlet pipe 3 and an outlet pipe 4 are connected to the pump suction host 2, the lower end of the outlet pipe 4 is installed on a ball screw mechanism 5, a sorting plate 6 is installed below the ball screw mechanism 5, several sets of sample bottles 8 are arranged below the sorting plate 6, the several sets of sample bottles 8 are placed on a tray 7, the tray 7 is movably installed in the cabinet 1, a cooling mechanism 9 is installed below the tray 7, several sets of flow channels 601 are opened on the sorting plate 6, and a liquid discharge hole 602 is opened at one end of the flow channel 601, the liquid discharge hole 602 is directly opposite the bottle mouth of the sample bottle 8.

[0026] Specifically, the inlet pipe 3 connects to the water pipe or sewage pipe of the river. In the initial state, the lower end of the outlet pipe 4 is located above a set of flow channels 601. When water sampling is required, the cooling mechanism 9 is turned on to ensure that the cabinet 1 is in a low-temperature state. The pumping unit 2 draws water from the water pipe or sewage pipe of the river through the inlet pipe 3. Then, the drawn water flows into the flow channel 601 below through the outlet pipe 4, and the water collects along the flow channel 601 to the drop hole 602. The water is then injected into the sample bottle 8 through the drop hole 602. After the specified amount of water sample is injected into the sample bottle 8, the pumping unit 2 is paused. The ball screw mechanism 5 drives the outlet pipe 4 to move to one side along the X-axis, so that the lower end of the outlet pipe 4 moves to the next set of flow channels 601. Then, the specified amount of water sample is injected into the next set of sample bottles 8. The same operation is performed, and the ball screw mechanism 5 moves the outlet pipe 4 along the X-axis. The water outlet pipe 4 moves along the distance, allowing the lower end of the water outlet pipe 4 to pass through each set of flow channels 601, thus dividing the water equally into multiple sample bottles 8. After sampling is completed, the tray 7, along with the sample bottles 8, can be pulled out of the cabinet 1 by pulling the tray 7, facilitating subsequent sample testing by the staff. Compared with existing technologies, the coordinated design of the sample dividing plate 6, the ball screw mechanism 5, and the tray 7 allows the water outlet pipe 4 to be divided into samples simply by moving along the X-axis, reducing the bending degree of the water outlet pipe 4 and increasing its service life. Secondly, it shortens the length of the water outlet pipe 4, making it easier for the staff to lay and install it. Since all the sample bottles 8 are placed on the tray 7, pulling the tray 7 allows all the sample bottles 8 to be removed from the cabinet 1 at once, and then the next set of prepared trays 7 can be placed in the cabinet 1, facilitating the staff to pick up and put away the sample bottles 8.

[0027] Example 2: Figures 3 to 5As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a sealing mechanism 603 is provided at the bottom of the sample plate 6. The sealing mechanism 603 includes two sets of first guide rails 6031, the first guide rails 6031 are fixedly installed at the bottom of the sample plate 6, a movable plate 6032 is slidably connected to the two sets of first guide rails 6031, a cylinder 6033 is fixedly installed on the outside of the cabinet 1 for driving the movable plate 6032, and two sets of sealing plates 6034 are symmetrically distributed on both sides of the movable plate 6032. The sealing plates 6034 are slidably installed on the bottom of the sample plate 6, and the extended portions on both sides of the movable plate 6032 are respectively located at the two sets of sealing plates. Inside the plate 6034, the sealing plate 6034 has an inclined groove 41, and the extension is provided with a pin 21. The end of the pin 21 is located in the inclined groove 41. One end of the water inlet pipe 3 is connected to the liquid inlet pipe 10. The liquid inlet pipe 10 includes a first electric three-way ball valve 101. The outlet end of the first electric three-way ball valve 101 is connected to the water inlet pipe 3. The two sets of water inlet ends on the first electric three-way ball valve 101 are respectively connected to pipe one 102 and pipe two 103. One end of pipe two 103 is connected to the outlet end of the second electric three-way ball valve 104. The two sets of water inlet ends on the second electric three-way ball valve 104 are respectively connected to pipe three 105 and pipe four 106.

[0028] Specifically, after sampling, the inner wall of the flow channel 601 will be contaminated with dirt from the water sample. In order not to affect the next set of sampling, the flow channel 601 needs to be cleaned. During cleaning, the sample plate 6 needs to be disassembled and then reinstalled after cleaning. This operation is not only troublesome, but also reduces the automation rate of the device. Pipe 102 connects to the water pipe or sewage pipe of the river. Pipe 3105 and Pipe 4106 connect to the cleaning fluid tank and the tap water tank, respectively. During sampling, the second electric three-way ball valve 104 is closed, and the inlet pipe 3 is interconnected with pipe 102. After sampling, the sample bottle 8 is replaced with a waste liquid bottle, and the second electric three-way ball valve 104 is opened to interconnect the inlet pipe 3, pipe 2103, and pipe 3105. Then, the cylinder 6033 pushes the movable plate 6032 to move. The movable plate 6032 drives the end of the pin 21 to slide along the inclined groove 41. Under the guidance of the inclined groove 41, the sealing plate 6034 moves towards the drop hole 602 until the sealing plate 6034 seals the lower end of the drop hole 602. Then, the pump suction host 2 is started to make pipe 3105 draw the cleaning fluid from the cleaning fluid tank and pass it through the ball bearing. The screw mechanism 5, in conjunction with the outlet pipe 4, fills each flow channel 601 with cleaning fluid. The cleaning fluid dissolves the dirt remaining in the flow channel 601. After the dirt is dissolved, the sealing plate 6034 is released from the lower end of the drain hole 602. The cleaning fluid, mixed with the dirt, flows into the waste liquid bottle through the drain hole 602. During this process, the second electric three-way ball valve 104 switches the connection between the inlet pipe 3, pipe two 103, and pipe four 106. After the waste liquid in the flow channel 601 is drained, the pump 2 is restarted to draw tap water from the water tank through pipe four 106. Then, each flow channel 601 is flushed through the outlet pipe 4, cleaning the flow channel 601. Through the coordination of the inlet pipe 10 and the sealing mechanism 603, the automatic cleaning of the flow channel 601 is achieved, improving the automation rate of the device.

[0029] Example 3: Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a series connection mechanism 604 is provided in the sample dividing plate 6. The series connection mechanism 604 includes a series connection tube 6041, which is fixedly installed in the sample dividing plate 6. A plurality of series connection ports 6042 are equally spaced on the series connection tube 6041, and the plurality of series connection ports 6042 are respectively directly opposite a plurality of flow channels 601. A cover plate 6043 is provided on the series connection ports. A lifting plate 6044 is movably installed below the series connection tube 6041. The lifting plate 6044 is equally spaced on the lifting plate 604. Several sets of connectors 6045 are attached to the top of the connectors 6045. The upper end of the connectors 6045 is connected to the cover plate 6043 and the waste liquid pipe 6046 is fixedly connected to one end of the series pipe 6041. One end of the waste liquid pipe 6046 is connected to the water pump 6047. Four sets of guide posts 6048 are installed at the bottom of the series pipe 6041. Four sets of through holes 6049 are opened on the lifting plate 6044. The through holes 6049 are slidably connected to the guide posts 6048. The inside of the series pipe 6041 is hollow. The inside of the series pipe 6041 is connected to several sets of flow channels 601 through several sets of series ports 6042.

[0030] Specifically, in the process of injecting cleaning fluid and tap water into the flow channel 601, the ball screw mechanism 5 is used to drive the water outlet pipe 4 to add fluid to multiple flow channels 601 one by one. Frequent position changes waste a lot of time and reduce the cleaning efficiency of the flow channel 601. Secondly, when treating waste liquid, staff need to pick up and put down the waste liquid bottle, which is troublesome and reduces the practicality of the device. In the initial state, the connecting port 6042 is blocked by the cover plate 6043, the water pump 6047 is in the off state, and the lifting plate 6044 is driven by two other sets of cylinders. When it is necessary to inject cleaning fluid and tap water into the flow channel 601, the drain hole 602 is first blocked by the sealing plate 6034. Then, the lifting plate 6044 is driven by two sets of cylinders to move upward along the guide post 6048. The lifting plate 6044 drives the corresponding cover plate 6043 to move upward through several sets of connecting parts 6045, so that the connecting port 6042 is opened. Then, the water outlet pipe 4 injects cleaning fluid into one of the flow channels 601. Liquid or tap water is supplied. The liquid flows into the connecting pipe 6041 through the connecting port 6042 in the flow channel 601. When the connecting pipe 6041 is full of liquid, the overflowing liquid flows into the corresponding flow channel 601 through several sets of connecting ports 6042, realizing the simultaneous addition of liquid to multiple sets of flow channels 601 and improving the efficiency of adding liquid to the flow channels 601. Secondly, when it is necessary to drain the liquid in the flow channel 601, the water pump 6047 is started. The water pump 6047 discharges the liquid in the connecting pipe 6041 along with the flow channel 601 through the waste liquid pipe 6046, realizing the automatic cleaning of waste liquid and improving the practicality of the device.

[0031] like Figures 7 to 9 As shown, the connector 6045 includes a connecting rod 31, which is movably inserted into the bottom of the connecting pipe 6041. A horizontal plate 32 is fixedly connected to the upper end of the connecting rod 31. Two sets of third guide rails 33 are symmetrically slidably installed on the horizontal plate 32. A cover plate 6043 is fixedly connected to the upper end of the third guide rails 33. A rotating rod 34 is rotatably installed inside the connecting rod 31. A gear 37 is installed at the upper end of the rotating rod 34. The gear 37 meshes with a rack 38. The cover plate 6043 is fixedly connected to the upper end of the rack 38. A rectangular shaft 35 is movably inserted into the rotating rod 34. A worm gear 36 is installed at the lower end of the rectangular shaft 35. Several sets of worm gears 36 mesh with a worm 605. The worm 605 is rotatably installed inside the cabinet 1. Several sets of support plates 606 are installed at equal intervals at the lower middle of the sample plate 6. The lower end of the rectangular shaft 35 is rotatably connected to the support plates 606.

[0032] Specifically, the above-mentioned method of opening the serial port 6042 by driving the sealing plate 6034 results in the water outlet pipe 4 being located directly above the sealing plate 6034. If the sealing plate 6034 is too close to the water outlet pipe 4, the liquid flowing out of the water outlet pipe 4 will fall directly onto the sealing plate 6034. The liquid will hit the sealing plate 6034, causing it to splash. The splashed liquid will fall onto the sample plate 6, making the sample plate 6 dirty. If the upward movement distance of the sealing plate 6034 is controlled, the sealing plate 6034 will be too close to the serial port 6042, affecting the rate at which the liquid enters the serial port 6042. Therefore, when it is necessary to open the serial port 6042, the lifting plate 6044 is driven upward by the cylinder. The lifting plate 6044 drives the connecting rod 31, together with the horizontal plate 32, the third guide rail 33, and the sealing plate 6034, to move upward, so that the serial port 6042 is opened. During this process, the rectangular shaft 35 slides along the inner cavity of the rotating rod 34. Then, the worm gear 605 is driven to rotate by the motor. The worm gear 605 drives the corresponding rectangular shaft 35 to rotate through several sets of worm gears 36. The rectangular shaft 35 drives the rotating rod 34 to rotate together with the gear 37. The rotating gear 37 drives the rack 38 to move together with the cover plate 6043. The cover plate 6043 drives the third guide rail 33 to slide along the horizontal plate 32. This not only makes the top of the serial port 6042 completely open, but also prevents the cover plate 6043 from being located directly below the water outlet pipe 4. While ensuring the liquid flow rate, it also prevents the liquid from splashing onto the sample plate 6.

[0033] Working principle: The cooling mechanism 9 is turned on to ensure that the cabinet 1 is in a low temperature state. The pump 2 draws water from the river pipe or sewage pipe through the water inlet pipe 3. The drawn water then flows into the flow channel 601 below through the water outlet pipe 4. The water collects at the drop hole 602 along the flow channel 601 and is injected into the sample bottle 8 through the drop hole 602. After the sample bottle 8 is injected with the specified amount of water sample, the pump 2 is paused. The ball screw mechanism 5 drives the water outlet pipe 4 to move to one side along the X-axis, so that the lower end of the water outlet pipe 4 moves to the next set of flow channels 601. Then, the specified amount of water sample is injected into the next set of sample bottles 8. The same operation is performed. The ball screw mechanism 5 moves the water outlet pipe 4 at equal distances along the X-axis, so that the lower end of the water outlet pipe 4 passes through each set of flow channels 601, so that the water is evenly distributed into multiple sample bottles 8. After the sampling is completed, the tray 7 and the sample bottles 8 can be removed from the cabinet 1 by pulling out the tray 7, so that the staff can test the samples. During sampling, the second electric three-way ball valve 104 is closed, and the inlet pipe 3 is connected to pipe 102. After sampling, the second electric three-way ball valve 104 is opened to connect the inlet pipe 3, pipe 2 103, and pipe 3 105. Then, the cylinder 6033 pushes the movable plate 6032 to move. The movable plate 6032 drives the end of the pin 21 to slide along the inclined groove 41. Guided by the inclined groove 41, the sealing plate 6034 moves towards the drop hole 602 until the sealing plate 6034 moves towards the drop hole 602. 34. Seal the lower end of the liquid discharge hole 602, then start the pump suction unit 2 to make the pipe 3 105 draw the cleaning fluid from the cleaning fluid tank. The cylinder drives the lifting plate 6044 to move upward. The lifting plate 6044 drives the connecting rod 31, along with the horizontal plate 32, the third guide rail 33, and the sealing plate 6034 to move upward, so that the serial port 6042 is opened. During this process, the rectangular shaft 35 slides along the inner cavity of the rotating rod 34. Then, the motor drives the worm gear 605 to rotate. The worm gear 605 passes through several sets of worms. Wheel 36 drives the corresponding rectangular shaft 35 to rotate. Rectangular shaft 35 drives rotating rod 34 and gear 37 to rotate together. The rotating gear 37 drives rack 38 and cover plate 6043 to move together. Cover plate 6043 drives third guide rail 33 to slide along horizontal plate 32. Water outlet pipe 4 injects cleaning fluid into one of the flow channels 601. The liquid flows into the connecting pipe 6041 through the connecting port 6042 in the flow channel 601. When the connecting pipe 6041 is full of liquid, the overflowing liquid flows through several... The cleaning fluid flows into the corresponding flow channel 601 through the serial port 6042, enabling the simultaneous addition of cleaning fluid to multiple flow channels 601. When it is necessary to drain the cleaning fluid from the flow channel 601, the water pump 6047 is started. The water pump 6047 drains the liquid from the serial pipe 6041 along with the liquid in the flow channel 601 through the waste liquid pipe 6046. Then the water pump 6047 is turned off again. In the same way, tap water is injected into the flow channel 601 to flush the flow channel 601. Finally, the waste liquid is discharged through the water pump 6047.
