Description

[Technical Field]

[0001] The present invention relates to the technical field of water quality detection, and more particularly to a device and method for rapid water quality detection. [Background technology]

[0002] The establishment of drinking water quality standards is related to many factors, such as people's living habits, culture, economic conditions, level of scientific and technological development, and the current state of water resources and water quality.

By installing components such as the buoyancy board, L-shaped lever, meshing gear, and brush, the mounting plate and the water quality detection lever are displaced relative to each other in the vertical direction, expanding the cleaning range of the brush and pushing out the telescopic tube, which then cooperates to clean the foreign matter that the brush has cleaned with the water flow discharged from the nozzle. 3. By installing components such as the position limiting rod, pressure ball, sliding block and nozzle, when thick impurities are encountered during cleaning by the brush, the repulsive force will be assisted by the soft pad, deflecting the position limiting rod and moving the sliding block downward, and furthermore, a stronger water flow will be ejected from the nozzle to clean the impurities, improving the efficiency of the equipment.

[0016] To facilitate understanding of the present invention, the present invention will now be described in more detail with reference to the accompanying drawings. The present invention is not limited to the embodiments set forth herein, but may be embodied in many different forms. On the contrary, the purpose of providing these embodiments is to provide a more complete disclosure of the present invention.

[0017] As shown in Figures 1 and 2, the water quality quick detection device of the present invention comprises a buoyancy board 1, a water quality detection lever 2 is provided at the center of the buoyancy board 1 so as to be able to slide up and down, a pull rope 3 is provided at the lower end of the water quality detection lever 2, a heavy ball 4 is provided at the lower end of the pull rope 3, an electric pull rod is provided inside the heavy ball 4, and the lower end of the pull rope 3 is connected to the electric pull rod inside the heavy ball 4, and a mounting plate 5 is provided at the lower end of the buoyancy board 1, the buoyancy board 1 provides buoyancy to the entire equipment and is used to float the equipment on the water surface, The quality detection lever 2 is used to detect the water quality of a water body. The heavy ball 4 is connected to the water quality detection lever 2 with the aid of the rope 3. After the heavy ball 4 falls to the bottom of the water, the water quality detection lever 2 floats in the water due to its own buoyancy. The pulling rope 3 prevents the detection depth of the water quality detection lever 2 from changing due to the influence of water surface waves. The heavy ball 4 is stored on an electric pulling rod, which winds the pulling rope 3 and can change the length of the pulling rope 3. When the length of the rope 3 is changed, the detection depth of the water quality detection lever 2 changes.

[0018] A disk 8 is provided at the top end of the buoyancy board 1, and the disk 8 is located at the top end of the water quality detection lever 2. A warning light 9 is provided on the disk 8, and a touch switch is provided at the bottom end of the disk 8. Because relative slippage occurs between the buoyancy board 1 and the water quality detection lever 2, when waves are generated on the water surface by the action of the outside wind, the buoyancy board 1 rises and falls with the changes in the water surface waves, and the relative movement distance between the buoyancy board 1 and the water quality detection lever 2 increases. As a result, the top of the water quality detection lever 2 comes into contact with the touch switch at the bottom end of the disk 8, causing the warning light 9 to flash, alerting the user to the wind environment conditions around the water body. When the water body becomes shallow, the top of the water quality detection lever 2 comes into contact with the touch switch at the bottom end of the disk 8, causing the warning light 9 to flash, alerting the user to the shallowness of the water body.

[0019] A slanted plate 10 is provided between the disk 8 and the buoyancy board 1, and a solar panel 11 is provided at the side end of the slanted plate 10 to supply power to the equipment, and a wireless transmitter is further provided on the disk 8. The solar panel 11 can supply power to the water quality detection lever 2, and water quality data detected by the water quality detection lever 2 can be transmitted to a terminal via the wireless transmitter for data analysis.

[0020] The buoyancy board 1 is provided with an attachment ring 12, which is attached with a horizontal rope 13, with a buoyancy ball 14 at the end of the horizontal rope 13, with a vertical rope 15 attached to the lower end of the buoyancy ball 14, with a fixed rod 16 at the lower end of the vertical rope 15, and with a hook claw 17 attached to the fixed rod 16. After the buoyancy ball 14, vertical rope 15, fixed rod 16, and hook claw 17 enter the water body, the hook claw 17 helps to fix the fixed rod 16 to the bottom of the water body, thereby keeping the buoyancy board 1 balanced in wind and waves, preventing the buoyancy board 1 from flipping over, and ensuring stable operation of the equipment.

[0021] When using this invention, workers board a boat to transport the equipment to the location in the water body to be measured, then dump the heavy ball 4 into the water, remotely operate the electric pulling rod inside the heavy ball 4 to control the length of the pulling rope 3, then dump the water quality detection lever 2 into the water, allowing it to float vertically in the water, then cover the water quality detection lever 2 with the buoyancy board 1, and with the help of the buoyancy board 1, dump the fixed rod 16, hook claw 17, and vertical rope 15 into the water, position the fixed rod 16 and hook claw 17 at the side end of the heavy ball 4, then dump the buoyancy ball 14 into the water, and use the horizontal rope 13 to connect and fix the buoyancy ball 14 to the buoyancy board 1, and use the hook claw 17 to fix the fixed rod 16 to the bottom of the water body, so that the buoyancy board 1 can maintain its balance in wind and waves and prevent it from tipping over.

[0022] Once the equipment is installed, the water quality detection lever 2 continues to detect the water quality of the water body, and the measurement data is transmitted to the terminal via the wireless transmitter for data analysis.

[0023] During operation of the equipment, the solar panel 11 provides power to the water quality detection lever 2, ensuring that the equipment can operate for a long period of time in the water body.

[0024] During the long-term water quality detection process in the water body, the device is prone to adhesion of floating organisms, shells and other substances to the water quality detection lever 2, which is likely to affect the detection data of the water quality detection lever 2. The adhesions on the water quality detection lever 2 need to be removed manually on a regular basis, which takes time and energy. At the same time, the detection position of the water quality detection lever 2 is not fixed, which is likely to affect the rationality of the detection data. Therefore, the following proposal is proposed: As shown in Figures 1 to 5, an annular turntable 501 is rotatably mounted at the bottom end of the mounting plate, a soft pad 502 is mounted inside the annular turntable 501, a brush 503 is mounted inside the soft pad 502, a nozzle 504 is mounted inside the mounting plate 5, an expandable tube 505 is mounted on the top of the mounting plate 5, a position limiting assembly 6 is further mounted inside the mounting plate 5, and an external gear 506 is mounted on the outside of the annular turntable 501, and when the annular turntable 501 rotates, it rotates the soft pad 502, which in turn rotates the brush 503, which is attached to the water quality detection lever 2. As the brush 503 rotates, it can clean any deposits on the water quality detection lever 2, making the detection data of the water quality detection lever 2 more accurate. Mounting frames 512 are provided on both sides of the mounting plate 5, and the mounting frames 512 are attached to the lower end of the buoyancy board 1. When the buoyancy board 1 floats up and down due to waves, the mounting plate 5 also floats up and down, causing relative displacement between the mounting plate 5 and the water quality detection lever 2. At this time, the L-shaped lever 7 and the meshing gear 507 also undergo relative displacement. However, the L-shaped lever 7 has an external thread 701 which is engaged with the internal thread of the meshing gear 507. Therefore, when the L-shaped lever 7 and the meshing gear 507 undergo relative displacement, the meshing gear 507 rotates, and the meshing gear 507 meshes with the external gear 506, causing the external gear 506 to rotate. As the annular rotating plate 501 rotates, the brush 503 can clean the surface of the water quality detection lever 2. As a result, a relative displacement occurs between the brush 503 and the water quality detection lever 2 in a vertical linear direction, and the cleaning area of ​​the brush 503 increases accordingly.

[0025] A slide groove 508 is provided inside the mounting plate 5, a slide block 509 is provided in the slide groove 508, and a nozzle 504 is provided at the side end of the slide block 509. A cavity is provided inside the mounting plate 5, and a connecting pipe 510 is provided in the slide groove 508. The connecting pipe 510 is connected to the nozzle 504 at an offset. When the slide block 509 moves down, the communication area between the connecting pipe 510 and the nozzle 504 increases. The water flow from the nozzle 504 moves the water body near the brush 503, thereby washing away the debris cleaned by the brush 503 and preventing the detection data of the water quality detection lever 2 from being affected. When the slide block 509 moves down, the communication area between the connecting pipe 510 and the nozzle 504 increases, and the water flow from the nozzle 504 increases, thereby increasing the speed of the water flow moving around the brush 503, improving the cleaning effect of the brush 503 and increasing the effectiveness of the equipment use.

[0026] The output end of the telescopic pipe 505 communicates with a hollow space within the mounting plate 5, and a suction pipe 511 is provided at the side end of the telescopic pipe 505. One-way valves are provided at both the suction pipe 511 and the output end of the telescopic pipe 505, and a pressure plate 18 is provided at the side end of the water quality detection lever 2, which is located at the upper end of the telescopic pipe 505. When the water quality detection lever 2 and the mounting plate 5 move relative to each other, the pressure plate 18 presses against the telescopic pipe 505, causing the telescopic pipe 505 to suck in and spray water with the one-way assistance of the suction pipe 511, supplying power to the nozzle 504 to spray water.

[0027] The position limiting assembly 6 includes a position limiting rod 601, a mounting rod 602 rotatably mounted on the position limiting rod 601, a torsion spring between the position limiting rod 601 and the mounting rod 602, the mounting rod 602 being mounted inside the mounting plate 5, a pressure ball 603 being mounted at the lower end of the position limiting rod 601 on one side adjacent to the soft pad 502, and the upper end of the position limiting rod 601 being located at the lower end of the slide block 509. When brush 503 is cleaning material attached to the outside of water quality detection lever 2, if the thickness of the attached material is large, brush 503 pushes out soft mat 502 during cleaning, thinning soft pad 502. In order to do this, pressure ball 603 moves toward soft pad 502 and deflects the top of position limiting rod 601. When the top of position limiting rod 601 is deflected, slide block 509 moves downward, increasing the communication area between connecting pipe 510 and nozzle 504, increasing the water flow discharged from nozzle 504, and increasing the flow rate of the water body moving around brush 503, thereby improving the cleaning effect of brush 503.

[0028] During the long-term detection process of the water quality detection lever 2, the water quality detection lever 2 is always located in the water body, so green algae and floating organisms will adhere to the water quality detection lever 2. When the buoyancy board 1 floats in the water body, waves will be generated on the water surface, and the presence of waves will cause the buoyancy board 1 to rise and fall along with the water surface. However, because the water quality detection lever 2 floats in the water body due to the action of the heavy ball 4 and the pulling rope 3, the water quality detection lever 2 will not rise and fall due to the influence of the water surface waves, and the water quality detection lever 2 and the buoyancy board 1 will be displaced vertically relative to each other. The L-shaped lever 7 is fixed to the water quality detection lever 2, the mounting plate 5 is fixed to the lower end of the buoyancy board 1 via the mounting frame 512, and the meshing gear 507 is rotatably installed at the lower end of the mounting frame 512, so that the L-shaped lever 7 will be displaced relative to the meshing gear 507.

[0029] During the process of relative displacement between the L-shaped lever 7 and the meshing gear 507, the meshing gear 507 has an internal thread and an external thread 701 on the outside of the L-shaped lever 7, so when the L-shaped lever 7 and the meshing gear 507 are displaced relative to each other, the meshing gear 507 rotates due to the action of the thread engagement, and when the meshing gear 507 rotates, it meshes with the external gear 506, causing the annular turntable 501 to rotate, and when the annular turntable 501 rotates, the soft pad 502 rotates, and the brush 503 cleans off any deposits on the outside of the water quality detection lever 2.

[0030] When the brush 503 cleans the outside of the water quality detection lever 2, the annular rotating disk 501 undergoes a relative vertical displacement with respect to the water quality detection lever 2, thereby increasing the cleaning range of the water quality detection lever 2 by the brush 503, improving the cleaning effect of the equipment, and ensuring that the water quality detection lever 2 can perform stable water quality detection.

[0031] On the other hand, when the buoyancy board 1 rises and falls along the water surface, a relative displacement occurs between the pressure plate 18 and the mounting plate 5, so that the pressure plate 18 presses against the telescopic tube 505. In the process of pressing against the telescopic tube 505, water enters the telescopic tube 505 from the suction pipe 511, but due to the action of the one-way valve, the water that has entered the telescopic tube 505 is forced into the hollow part of the mounting plate 5, and the water in the hollow part of the mounting plate 5 passes through the connecting pipe 510 and enters the nozzle 504, and the nozzle 504 discharges a water flow to the position to be cleaned by the brush 503, causing a water flow impact on the position to be cleaned by the brush 503, so that the debris cleaned by the brush 503 can be easily discharged, thereby improving the cleaning effect of the equipment.

[0032] As the brush 503 cleans the outside of the water quality detection lever 2, if the thickness of the deposits on the outside of the water quality detection lever 2 increases, the resistance force that the brush 503 experiences as it cleans increases accordingly, and the repulsive force that the brush 503 exerts on the soft pad 502 as it cleans increases, pressing down on the soft pad 502 and thinning it. As the soft pad 502 becomes thinner, the torsion spring action of the position limiting rod 601 causes the pressure ball 603 to move toward the soft pad 502, deflecting the position limiting rod 601. When the position limiting rod 601 is deflected, the position limiting position of the position limiting rod 601 relative to the slide block 509 drops, causing the slide block 509 to move downward. However, as the slide block 509 moves downward, the communication range between the connecting pipe 510 and the nozzle 504 increases, allowing more water to be discharged from the nozzle 504 and enabling the brush 503 to more effectively clean the thick deposits on the water quality detection lever 2.

[0033] The present invention provides a detection method for a water quality rapid detection device, Step 1: After the worker boards a boat and transports the equipment to the location in the water body to be measured, he throws the heavy ball 4 into the water, and controls the length of the pulling rope by remotely operating the electric pulling rod 3 inside the heavy ball 4, and then throws the water quality detection lever 2 into the water, making the water quality detection lever 2 float vertically in the water, and then covers the water quality detection lever with a buoyancy board 1, and with the help of the buoyancy board 1, makes the water quality detection lever 2 float vertically in the water body; Step 2: Throwing the fixed rod 16, hook claw 17, and vertical rope 15 into the water, positioning the fixed rod 16 and hook claw 17 at the side end of the heavy ball 4, then throwing the buoyancy ball 14 into the water, connecting and fixing the buoyancy ball 14 and the buoyancy board 1 with the help of the horizontal rope 13, and fixing the fixed rod 16 to the bottom of the water body with the help of the hook claw 17, so that the buoyancy board 1 can maintain its balance in wind and waves; Step 3 includes: once the installation of the equipment is complete, the water quality detection lever 2 continues to detect the water quality in the water body, and the measurement data is transmitted to the terminal via the wireless transmitter for data analysis; and the solar panel 11 provides power to the water quality detection lever 2, ensuring that the equipment can operate for a long period of time in the water body.

[0034] The main function of the present invention is that when waves occur on the water surface, the buoyancy board 1, L-shaped lever 7, meshing gear 507, telescopic tube 505, brush 503 and other components engage with the meshing gear 507, causing it to rotate, which in turn rotates the brush 503 to clean the outside of the water quality detection lever 2. Since the mounting plate 5 and the water quality detection lever 2 are displaced vertically relative to each other, the brush 503 expands its cleaning range and presses on the telescopic tube 505, causing the water flow from the nozzle 504 to assist in cleaning the debris already cleaned by the brush 503. If thick impurities are found during the cleaning process of the brush 503, the repulsive force presses on the soft pad 502, deflecting the position limiting rod 601 and moving the slide block 509 downward, which in turn causes the nozzle 504 to emit a stronger water flow for further cleaning, thereby improving the effectiveness of the equipment.

[0035] The rapid water quality detection device of the present invention can be mounted, connected or installed by any conventional mechanical method, and can be implemented in any manner that can achieve its beneficial effects.
