Description

Technical Field

[0001] This utility model belongs to the field of water sample testing technology, specifically an online water sample testing device for water plants. Background Technology

[0002] Water sample testing at water plants is a core component of ensuring drinking water safety, spanning the entire process from raw water entering the plant to the water treatment process, finished water leaving the plant, and finally, pipeline transportation. Its core objective is to strictly control water quality risks. This process involves using specialized instruments, reagents, and methods to analyze the physical properties, chemical composition, and biological indicators of water bodies (such as drinking water, surface water, groundwater, and industrial wastewater). The primary purpose is to determine whether the water quality meets specific standards (e.g., for drinking, irrigation, or industrial use), identify pollution sources, or assess the ecological health of the water body. However, existing testing equipment often encounters suspended particles in the water samples. These particles directly interfere with the detection of various indicators, leading to inflated or distorted results. Filtration of the water samples is necessary, but the filters are bolted on and require specialized tools for installation and removal, making the process cumbersome. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an online water sample testing device for water plants. It solves the problem that when the water sample is used, it often contains suspended particles, which directly interfere with the detection process of various indicators, resulting in falsely high or distorted results. The water sample needs to be filtered, but the filter screen is installed with bolts, and disassembly and assembly require the use of corresponding tools, which is quite troublesome.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online water sample testing device for a water plant, comprising a tester, a mounting box fixedly connected to one side of the top of the tester, a slot provided in the middle of one side of the mounting box, two rotating rods rotatably connected at both ends of the mounting box at the slot opening via pins, a limiting groove provided at one end of each rotating rod, a mounting frame slidably connected through the slot, a filter screen fixedly connected inside the mounting frame, two connecting frames fixedly connected to one side of the mounting frame, a sliding rod slidably connected through the top of each connecting frame, a limiting block fixedly connected through the bottom of each sliding rod passing through the connecting frame, the limiting block corresponding to the limiting groove, and a spring sleeved on the surface of the sliding rod between the limiting block and the connecting frame.

[0005] As a further embodiment of this utility model: a liquid inlet pipe is fixedly connected to the top of the mounting box, and a movable cover is snapped onto the top of the liquid inlet pipe, the movable cover being tightly fitted to the top of the mounting box.

[0006] As a further embodiment of this utility model: two guide blocks are symmetrically and fixedly connected inside the mounting box at the bottom of the slot, and a light-emitting tube is fixedly connected to the bottom of the inner wall of the mounting box.

[0007] As a further embodiment of this utility model: a glass frame is slidably connected through the middle position of the bottom of the mounting box, and the glass frame is positioned corresponding to the two guide inclined blocks.

[0008] As a further embodiment of this utility model: a connecting seat is fixedly connected to one side of the glass frame, the connecting seat is slidably connected to the mounting box, and two plug-in blocks are fixedly connected to the side of the connecting seat away from the glass frame.

[0009] As a further embodiment of this utility model: the mounting box is fixedly connected to sliding seats on both sides of the connecting seat, and a pin is slidably connected through the sliding seat, and the pin is inserted into the plug block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The online water sample testing device for this water plant, by setting up an installation frame, a sliding rod, a limiting block, and a rotating rod, allows the filter screen to be installed inside the installation box after the installation frame is inserted into the limiting groove. Rotating the rotating rod causes it to rotate into the connecting frame, while simultaneously pressing the limiting block, which in turn causes the limiting block to rotate along with the sliding rod and the spring. This causes the spring to deform and generate relative elastic force. As the rotating rod is fully rotated into the connecting frame, the spring, through its elastic force, causes the limiting block to reset and engage with the slot, thus fixing the rotating rod and completing the rapid installation of the installation frame. 2. The online water sample testing device for this water plant, by setting up a pin, a connecting seat, a glass frame, and a plug-in block, aligns the glass frame with the opening on one side of the installation box, moves the glass frame to insert it into the installation box, and as the glass frame continues to move, it causes the connecting seat to press against one side of the installation box. Moving the pin causes the pin to slide and engage with the plug-in block, thereby fixing and limiting the connection seat and the glass frame. When it is necessary to remove the glass frame, moving the pin causes the pin to disengage from the plug-in block, and the glass frame and the connecting seat can be removed, thus achieving quick assembly and disassembly of the glass frame.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: an online water sample testing device for a water plant, including a tester 1, an installation box 2 fixedly connected to one side of the top of the tester 1, an inlet pipe 12 fixedly connected to the top of the installation box 2, a movable cover 13 snapped onto the top of the inlet pipe 12, the movable cover 13 being tightly attached to the top of the installation box 2, by setting the movable cover 13, the movable cover 13 covers the top of the inlet pipe 12, thereby achieving light shielding of the inlet pipe 12 and reducing the influence of external factors on the tester 1; Inside the mounting box 2, two guide blocks 14 are symmetrically fixedly connected at the bottom of the slot 3. A light-emitting tube 15 is fixedly connected to the bottom of the inner wall of the mounting box 2. By setting the guide blocks 14, the guide blocks 14 can guide the filtered water sample, allowing the water sample to flow into the glass frame 16 for testing. A glass frame 16 is slidably connected through the middle of the bottom of the mounting box 2. The glass frame 16 is positioned opposite to the two guide blocks 14. A connecting seat 17 is fixedly connected to one side of the glass frame 16. The connecting seat 17 is slidably connected through the mounting box 2. Two plug-in blocks 18 are fixedly connected to the side of the connecting seat 17 away from the glass frame 16. By setting the connecting seat 17, the connecting seat 17 moves with the glass frame 16 and abuts against one side of the mounting box 2, so that the connecting seat 17 can cooperate with the mounting box 2 to perform sealing treatment and reduce the influence of external light on the glass frame 16. Mounting box 2 has sliding seats 19 fixedly connected to both sides of connecting seat 17. A pin 20 is slidably connected through the sliding seat 19. The pin 20 is inserted into the plug block 18. By setting the pin 20, the pin 20 is inserted into the plug block 18, thereby fixing the connecting seat 17 through the plug block 18, so that the connecting seat 17 and the glass frame 16 can be fixedly installed inside the mounting box 2. A slot 3 is provided in the middle of one side of the installation box 2. Two rotating rods 4 are rotatably connected at both ends of the installation box 2 at the opening of the slot 3 via pins. A limit groove 5 is provided at one end of the rotating rod 4. An installation frame 6 is slidably connected through the slot 3. A filter screen 7 is fixedly connected inside the installation frame 6. By setting the filter screen 7, the water sample entering the installation box 2 through the liquid inlet pipe 12 falls on the surface of the filter screen 7, so that the filter screen 7 can filter the water sample and filter out the large particles in the water sample and leave them on the surface of the filter screen 7. Two connecting frames 8 are fixedly connected to one side of the mounting frame 6. A sliding rod 9 is slidably connected through the top of the connecting frame 8. A limiting block 10 is fixedly connected through the bottom of the sliding rod 9 through the connecting frame 8. The limiting block 10 is positioned corresponding to the limiting groove 5. A spring 11 is sleeved on the surface of the sliding rod 9 between the limiting block 10 and the connecting frame 8. By setting the sliding rod 9, when the limiting block 10 drives the spring 11 to move, the limiting block 10 simultaneously drives the sliding rod 9 to slide inside the connecting frame 8. Thus, the connecting frame 8 limits the limiting block 10 and the spring 11 through the sliding rod 9, making the movement of the limiting block 10 and the spring 11 more stable.

[0014] The working principle of this utility model is as follows: After aligning the mounting frame 6 with the slot 3, move the mounting frame 6 so that it pulls the filter screen 7 into the mounting box 2. With the mounting frame 6 pressed against the inside of the mounting box 2, rotate the rotating rod 4. The rotating rod 4 rotates into the connecting frame 8 while simultaneously pressing the limiting block 10, causing the limiting block 10 to move upwards and compress the spring 11. This causes the spring 11 to deform and generate a relative elastic force. As the rotating rod 4 fully rotates into the connecting frame 8, the limiting groove 5 aligns with the limiting block 10. The spring 11, through its elastic force, causes the limiting block 10 to reset and engage with the limiting groove 5. The mounting frame 6 is fixed inside the mounting box 2. The glass frame 16 is aligned and inserted into the mounting box 2, so that the connecting seat 17 on one side of the glass frame 16 abuts against the surface of the mounting box 2. The movable pin 20 is inserted into the connecting seat 17 to complete the fixed installation of the glass frame 16. The water sample is poured into the mounting box 2 through the liquid inlet pipe 12, so that the water sample comes into contact with the filter screen 7. After being filtered by the filter screen 7, it is guided by the guide inclined block 14 and falls into the glass frame 16, so that the light-emitting tube 15 can test the water sample inside the glass frame 16.
