Description

Technical Field

[0001] This invention relates to the field of water pollution source identification technology, and more particularly to a water pollution source identification device. Background Technology

[0002] Water pollution has a significant impact on ecosystems. In particular, industrial emissions, agricultural fertilizers, and acidic soil runoff can affect the acidity or alkalinity of water. Different types of aquatic organisms have different tolerances to water pH. The optimal pH range for most freshwater fish and other aquatic organisms is usually between 6.5 and 8.5. Too low (acidic) or too high (alkaline) pH values ​​can lead to the death of fish and aquatic organisms, harm the ecosystem, and affect biodiversity. Therefore, it is necessary to conduct regular water quality monitoring to identify water pollution sources. Identification devices are generally used, but most existing water pollution source identification devices still have problems that need to be solved during use.

[0003] Most existing water pollution source identification devices use pH meters to detect the acidity or alkalinity of water. However, in most existing water pollution source identification devices, the pH meter is fixed to the outer casing of the device with screws. When identifying water pollution sources, the device needs to be immersed in water. The screws are prone to rust and stripping, increasing the difficulty of tightening the screws. This makes it inconvenient to install and remove the pH meter. Later maintenance requires removing the pH meter. If the operation is complicated, it will take a lot of time and effort, affecting efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water pollution source identification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The water pollution source identification device proposed in this invention includes a housing. A circular tube is slidably connected to the inner wall of the housing. A circular plate is fixedly connected to one side of the circular tube. Two fixed plates are fixedly connected to the circular plate on the side away from the circular tube. Two first guide rods are arranged between the two fixed plates and are fixedly connected to the fixed plates. Two grippers are arranged between the two fixed plates and are sleeved on the first guide rods. The grippers are slidably connected to the first guide rods. A fixing block is arranged between the two grippers. Two positioning rods are inserted through the bottom of the fixing block and are fixedly connected to the circular plate. A pH meter is fixed to the fixing block by screws. Two fixed rods are fixedly connected to the top of the grippers. The top of the two fixed rods on the same side is fixedly connected to the same square plate. A guide groove is formed on the square plate, and a limit rod is arranged in the guide groove. The limit rod is slidably connected to the square plate and is fixedly connected to the outer wall of the housing. This device utilizes a technology that allows the two grippers to approach each other while the circular tube extends. This method involves bringing the two grippers close together until they enclose the fixing plate, thus limiting and clamping the plate and installing the pH meter. Retracting the tube moves the grippers away, removing the pH meter from the fixing plate, and the device can then be removed. This effectively solves the problem mentioned in the background section: most existing water pollution source identification devices use pH meters to detect the acidity or alkalinity of water. However, in most existing devices, the pH meter is fixed to the outer casing with screws. Identifying water pollution sources requires immersing the device in water, and the screws are prone to rust and stripping, increasing the difficulty of tightening them. This makes it inconvenient to install and remove the pH meter, and subsequent maintenance requires removing the meter. If the operation is complex, it consumes a lot of time and effort, affecting efficiency. This method simplifies operation, facilitates the installation and removal of the pH meter, shortens equipment deployment and maintenance time, and allows monitoring personnel to identify water pollution sources more quickly, effectively improving work efficiency.

Retracting the tube moves the grippers away, releasing the clamp and allowing the pH meter to be removed.

The inner walls of the first fixing ring 17 and the second fixing ring 18 are rotatably connected to a first connecting rod 19. The first connecting rod 19 rotates within the second fixing ring 18 and the first fixing ring 17 to ensure the stability of the worm gear 20 when it rotates. The outer wall of the first fixing ring 17 is fixedly connected to the inner wall of the outer shell 1.

[0024] In this invention, one of the first connecting rods 19 is fixedly connected to the adjusting screw 16, and the two first connecting rods 19 are fixedly connected to the same worm gear 20 on their respective sides. A worm 21 adapted to the worm gear 20 is provided on one side of the worm gear 20. The outer shell 1 is fixedly connected to the mounting box 22 on the side close to the worm gear 20. The mounting box 22 is fixedly connected to the fixing seat 1203. The inner wall of the mounting box 22 is fixedly connected to the second fixing ring 18. The worm 21 passes through the mounting box 22, and a rotating wheel 23 is provided on one side of the worm 21.

[0025] In this invention, the mounting box 22 is fixedly connected to a handle 24 on the side away from the outer shell 1.

[0026] In this invention, a take-up roller 25 is provided on one side of the mounting box 22. The take-up roller 25 is fixedly connected to a worm gear 21. A rotating wheel 23 is fixedly connected to the side of the take-up roller 25 away from the worm gear 21. A wire fastener 26 is fixedly connected to the outer wall of the take-up roller 25. A data transmission line 27 is provided on the wire fastener 26. A toothed ring 28 is fixedly connected to the outer wall of the take-up roller 25 near the mounting box 22. The toothed ring 28 is meshed with a gear 29. A rotating shaft 30 is fixedly connected to one side of the gear 29. A bearing housing 31 is fitted onto a rotating shaft 30. The inner wall of the bearing ring on the bearing housing 31 is fixedly connected to the rotating shaft 30. The bearing housing 31 is fixedly connected to a mounting box 22. A reciprocating screw 32 is fixedly connected to one side of the rotating shaft 30. A baffle 33 is fixedly connected to the reciprocating screw 32 on the side away from the gear 29. A screw sleeve 34 is fitted onto the reciprocating screw 32. A pin hole is provided radially on the inner circumferential surface of the screw sleeve 34. A crescent pin that mates with the reciprocating screw 32 is provided in the pin hole. A first threading block 35 is fixedly connected to the outer wall of the lead screw sleeve 34. The data transmission line 27 passes through the first threading block 35. A sliding plate 36 is fixedly connected to the outer wall of the lead screw sleeve 34. A fifth guide rod 37 is threaded through the sliding plate 36. The sliding plate 36 is slidably connected to the fifth guide rod 37. The fifth guide rod 37 is fixedly connected to the side plate 38. The side plate 38 is fixedly connected to the mounting box 22. A display screen 40 is provided at one end of the data transmission line 27. The connector of the data transmission line 27 is inserted into the input end of the display screen 40. The connector of the data transmission line 27 at the end away from the display screen 40 is inserted into the output end of the pH detector 7. Due to the adoption of the technology of coaxial rotation of the take-up roller and the worm gear, the line can be unloaded when the round tube is extended and the line can be retracted when the round tube is retracted. In addition, the first threading block can move back and forth during the unloading and retraction process, so as to evenly unload and retract the line, thereby achieving the technical effect of easy storage of the data transmission line.

[0027] In this invention, the data transmission line 27 is provided with two second wire-passing blocks 39, and both second wire-passing blocks 39 are fixedly connected to the outer wall of the outer shell 1.

[0028] Working principle: Assemble the device by fixing the fixing block 6 to the pH meter 7 with screws, positioning the fixing block 6 on the positioning rod 601, inserting the other end connector of the data transmission cable 27 into the interface on the display screen 40, placing the fixing block 6 between the two grippers 5, and then rotating the rotating wheel 23. The rotating wheel 23 will drive the winding roller 25 to rotate, which in turn will drive the worm gear 21 to rotate, which in turn will drive the worm wheel 20 to rotate, which in turn will drive the first connecting rod 19 to rotate, which in turn will drive the adjusting screw 16 to rotate, which in turn will drive the screw nut 15 to move, which in turn will drive the round tube 2 to move, which in turn will drive the round plate 3 to move, which in turn will drive the fixing plate 4 to move. The fixed plate 4 will drive the first guide rod 401 to move, which in turn will drive the gripper 5 to move. As the gripper 5 moves, the fixed rod 8 will move, which in turn will drive the square plate 9 to move. The movement of the square plate 9 will also drive the second guide rod 12 to move, which in turn will drive the guide plate 1201 to move. The guide plate 1201 will move along the fourth guide rod 1202, ensuring the stability of the square plate 9 during movement. The square plate 9 will be compressed by the limiting rod 11 during movement. The limiting rod 11 will move within the guide groove 10. As the square plate 9 moves away from the handle 24, it will also move closer to each other, which will cause the two fixed rods 8 to move closer to each other, and thus the two grippers 5 to move closer to each other. When passing the bend in the guide groove 10, the two grippers 5 will contact each other, enveloping and holding the fixing block 6, thus installing the pH meter 7. During the rotation of the take-up roller 25, the wire can be unloaded. The pH meter 7 moves with the data transmission line 27, which moves within the second threading block 39 and the first threading block 35. Depending on the detection area, the rotating wheel 23 is rotated to adjust the length of the protruding tube 2 to fit the detection range. The other end of the data transmission line 27 is inserted into the interface on the display screen 40. The pH meter 7 is then immersed in water to detect the acidity or alkalinity of the water. If the pH value is below 7, it indicates that the water is acidic and may be affected by acidic wastewater (such as industrial discharge, agricultural fertilizers, acidic soil, and rainwater). Pollution from runoff, etc., indicates that the water body is alkaline if the pH value is higher than 7, which may be affected by alkaline pollution sources (such as some industrial wastewater). The data detected by the pH meter 7 is transmitted to the display screen 40 through the data transmission line 27. The operator can observe the detected data through the display screen 40. After the test is completed, the pH meter 7 is removed from the water, and the rotating wheel 23 is reversed to retract the round tube 2. If the limit rod 11 moves again past the bend of the guide groove 10 and continues to move, the two square plates 9 will move away from each other, and the two grippers 5 will move away from each other, thus releasing the clamping of the fixing block 6 and removing the fixing block 6, which in turn allows the pH meter 7 to be removed. During the process of reversing the rotating wheel 23, the take-up roller 25 will also be reversed.Remove the connector of the data transmission cable 27 from the interface on the display screen 40. Reversing the take-up roller 25 will then take in the cable. The rotation of the take-up roller 25 will also drive the gear ring 28 to rotate, which in turn drives the gear 29. The gear 29 will then drive the reciprocating lead screw 32 to rotate, which in turn drives the lead screw sleeve 34 to move back and forth. This movement of the lead screw sleeve 34 will then drive the first threading block 35 to move back and forth, ensuring that the data transmission cable 27 is evenly wound onto the take-up roller 25. The movement of the lead screw sleeve 34 will also drive the sliding plate 36 to move. The sliding plate 36 will move along the fifth guide rod 37, ensuring the stability of the first threading block 35 during movement.
