Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water collection device for river water quality testing. Background Technology

[0002] In the process of river water quality monitoring, water collection devices are needed to collect water samples.

[0003] A portable stratified water sampler, disclosed in CN211856019U, includes an upper sleeve, a sampling tube, and a solid cone. The sampling tube is closed at both ends and divided into several sampling intervals by partitions. A funnel-shaped tray is installed at the bottom of each sampling interval, and the outlet of the funnel-shaped tray is connected to the inlet of a water sample conduit. The inlet of the water sample conduit is connected to an external valve. Several sampling ports are spaced from top to bottom on the side wall of the sampling tube, and each sampling port corresponds to a sampling interval. A handle is installed inside the upper sleeve, and the lower end of the handle is connected to the top surface of the sampling tube via a rotary joint. The upper end of the handle extends out from the upper sleeve. A compartment connecting the sampling ports is provided around the sampling tube, and a door plate for opening and closing the sampling ports is provided inside the compartment. The upper end of the door plate is connected and fixed to the handle via a connecting plate. This sampler can perform stratified sampling simultaneously in the water body, avoiding repeated insertion into the water body during the sampling process, reducing interference and damage to the sampled water body, and improving the accuracy and quality of water sample collection. However, because this portable stratified water sampler requires sampling in stratified sections, the sampling tube is quite long and cannot be retracted, making it inconvenient to store and carry.

[0004] Therefore, a water collection device for river water quality testing has now been developed that is retractable, reduces space occupation, and is easy to store and carry. Utility Model Content

[0005] To overcome the shortcomings of existing portable stratified water samplers, which require stratified sampling tubes, are long, cannot be retracted, and are inconvenient to store and carry, this utility model provides a retractable water collection device for river water quality testing that reduces space occupation and is easy to store and carry.

[0006] A water collection device for river water quality testing includes a connecting block, an outer sampling tube, a middle sampling tube, an inner sampling tube, a telescopic rod, an inner sampling block, a middle sampling block, an outer sampling block, a motor, gears, a limiting block, a baffle, and a docking assembly. The outer sampling tube is connected to the upper left side of the connecting block, and the middle sampling tube is connected to the upper left side of the connecting block. The middle sampling tube is located to the right of the outer sampling tube. The telescopic rod is rotatably connected to the middle of the connecting block. The upper side of the telescopic rod is connected to the inner sampling tube, and the lower side of the connecting block is connected to the inner sampling block. The inner sampling block and the telescopic rod are connected to each other. The rod is connected by a rotating mechanism. The inner sampling block is threadedly connected to the middle sampling block, and the middle sampling block is threadedly connected to the outer sampling block. A motor is connected to the right side of the connecting block, and a gear is connected to the output shaft of the motor. A gear ring is provided on the upper part of the telescopic rod, and the gear meshes with the gear ring. A baffle is connected to the lower side of the telescopic rod, and the baffle is rotatably connected to the outer sampling block. A limit block is connected to the lower side of the baffle, and the limit block is slidably connected to the outer sampling block. An outer sampling hole is opened on the baffle. Both the inner and middle sampling blocks are equipped with docking components that can easily connect to the sampling tube.

[0007] To further clarify, sampling holes are provided on the telescopic rod.

[0008] To further explain, the motor and processor are electrically connected through the control module.

[0009] To further explain, it also includes lifting rings, with multiple lifting rings rotatably connected to the upper side of the connecting block.

[0010] To further explain, the docking assembly includes an iron ring, a corrugated pipe, and an electromagnet. The upper sides of both the middle and outer sampling blocks are connected to corrugated pipes, and the upper sides of the corrugated pipes are connected to iron rings. The lower sides of both the outer and middle sampling pipes are connected to electromagnets. The electromagnets and the processor are electrically connected through a control module.

[0011] To further explain, it also includes a float valve, which is installed on all bellows.

[0012] The beneficial effects of this utility model are as follows: By starting the motor, the gear rotates in the opposite direction and meshes with the gear ring, causing the baffle to rotate in the opposite direction and block the outer sampling hole. Then, the limiting block drives the outer sampling block to rotate in the opposite direction, causing the outer sampling block to move upward and close the middle sampling block. Then, the middle sampling block moves upward and closes the inner sampling block. This achieves the effect of being retractable, reducing space occupation, and facilitating storage and carrying.

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0020] A water collection device for river water quality testing, such as Figures 1-5As shown, the assembly includes a lifting ring 1, a connecting block 2, an outer sampling tube 3, a middle sampling tube 4, an inner sampling tube 5, a telescopic rod 6, an inner sampling block 7, a middle sampling block 8, an outer sampling block 9, a motor 10, a gear 11, a limiting block 12, a baffle 13, and a docking assembly. Three lifting rings 1 are rotatably connected to the upper side of the connecting block 2. The outer sampling tube 3 is connected to the upper left side of the connecting block 2. The middle sampling tube 4 is connected to the upper left side of the connecting block 2 and is located to the right of the outer sampling tube 3. The telescopic rod 6 is rotatably connected to the middle of the connecting block 2. The inner sampling tube 5 is connected to the upper side of the telescopic rod 6. The inner sampling block 7 is connected to the lower side of the connecting block 2. A sampling hole is opened on the telescopic rod 6 to facilitate the collection of water from the inner sampling block 7. Similarly, the inner sampling block 7 is rotatably connected to the telescopic rod 6, the lower side of the inner sampling block 7 is threadedly connected to the middle sampling block 8, the lower side of the middle sampling block 8 is threadedly connected to the outer sampling block 9, the right side of the connecting block 2 is connected to the motor 10, the motor 10 and the processor are electrically connected through the control module, the output shaft of the motor 10 is connected to the gear 11, the upper part of the telescopic rod 6 is provided with a gear ring, the gear 11 meshes with the gear ring, the lower side of the telescopic rod 6 is connected to the baffle 13, the baffle 13 is rotatably connected to the outer sampling block 9, the lower side of the baffle 13 is connected to the limit block 12, the limit block 12 is slidably connected to the outer sampling block 9, the baffle 13 has an outer sampling hole 14, and both the inner sampling block 7 and the middle sampling block 8 are provided with docking components.

[0021] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the docking assembly includes an iron ring 15, a bellows 16, a float valve 17, and an electromagnet 18. The upper sides of the middle sampling block 8 and the outer sampling block 9 are both connected to the bellows 16, and the upper sides of the bellows 16 are both connected to the iron ring 15. The bellows 16 are both equipped with float valves 17. The lower sides of the outer sampling tube 3 and the middle sampling tube 4 are both connected to the electromagnet 18. The electromagnet 18 and the processor are electrically connected through a control module.

[0022] When using this utility model, firstly, the connecting block 2 is lowered to the water surface via the lifting ring 1, so that the inner sampling block 7, the middle sampling block 8, and the outer sampling block 9 are immersed in the water. After reaching the specified depth, the processor starts the motor 10 through the control module, which drives the gear 11 to rotate and mesh with the gear ring, causing the telescopic rod 6 to rotate, which in turn drives the baffle 13 to rotate, so that the outer sampling hole 14 is connected to the outer sampling block 9. At this time, the limiting block 12 contacts the outer sampling block 9. After the baffle 13 continues to rotate, the limiting block 12 drives the outer sampling block 9 to rotate, so that the outer sampling block 9 moves downward along the middle sampling block 8. After the outer sampling block 9 moves to the limit, the outer sampling block 9 drives the middle sampling block 8 to rotate, so that the middle sampling block 8 moves downward, so that the inner sampling block 7, the middle sampling block 8, and the outer sampling block 9 are located at different depths in the water for sampling.

[0023] After sampling is completed, the processor starts the motor 10 through the control module, which drives the gear 11 to rotate in the opposite direction and mesh with the gear ring. This causes the baffle 13 to rotate in the opposite direction and block the outer sampling hole 14. Then, the limiting block 12 drives the outer sampling block 9 to rotate in the opposite direction, causing the outer sampling block 9 to move upward and close the middle sampling block 8. Then, the middle sampling block 8 moves upward and closes the inner sampling block 7, thereby achieving telescopic movement, reducing space occupation, and facilitating storage and carrying. Afterward, the connecting block 2 is moved out of the water surface through the lifting ring 1.

[0024] After the outer sampling block 9 and the middle sampling block 8 move upward, the electromagnet 18 is energized, causing the electromagnet 18 to attract the iron ring 15. The bellows 16 is then connected to the outer sampling tube 3 and the middle sampling tube 4 respectively. After that, the outer sampling tube 3, the middle sampling tube 4, and the inner sampling tube 5 are connected to external water pumps to extract the water samples from the inner sampling block 7, the middle sampling block 8, and the outer sampling block 9. The float valve 17 is used to prevent the water samples from flowing back.
