[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides a water quality detection device for non-negative pressure water supply equipment, including a water supply tank 1, and also including: a detection box 5, the detection box 5 is connected to the water supply tank 1 through a water pipe, and the outer wall of the detection box 5 is fixedly connected to the support base 2; a feeding mechanism 3, the feeding mechanism 3 is arranged on the support base 2; a stirring mechanism 4, the stirring mechanism 4 is arranged on the inner wall of the detection box 5; a cylinder 6, the cylinder 6 is fixedly connected to the top outer wall of the support base 2, and the movable end of the cylinder 6 is fixedly connected to the detector 7;

[0030] Among them, the unloading mechanism 3 includes a driving assembly, which is arranged in the inner wall of the support seat 2 through a reset spring A309; the stirring mechanism 4 includes a motor 401, and the output shaft of the motor 401 is fixedly connected to the rotating rod 402.

[0031] The above scheme is adopted: the water supply tank 1 is the main body of the non-negative pressure water supply equipment, which is the existing technology. It is connected to the detection box 5 through a water pipe, and a valve is provided on the water pipe. When the water quality needs to be tested, the valve can be opened to allow the water supply tank 1 to supply water to the detection box 5, and then the detector 7 is driven downward by the cylinder 6 to contact the water in the detection box 5, and the detection is performed by the detector 7. During the detection process, the purifier can be added to the detection box 5 through the feeding mechanism 3, and the operator does not need to add it manually, which reduces the work intensity and facilitates the operation; after the purifier is added, the water and the purifier can be stirred and mixed by the stirring mechanism 4 to make the purifier more uniform, thereby ensuring the accuracy of the detection; a water outlet is provided at the bottom of the detection box 5, and a valve is provided on the water outlet. The valve is closed during the detection process, and the valve can be controlled to open after the detection is completed to discharge the tested water.

[0032] like Figures 2 to 4 As shown, the top outer wall of the support seat 2 is fixedly connected to the purification agent box 301, the outer wall of the purification agent box 301 is provided with a liquid storage tube 302 through a connecting tube 307, the outer wall of the liquid storage tube 302 is fixedly connected to the liquid outlet 303, the inner wall of the liquid outlet 303 is fixedly connected to a one-way valve 304, the inner wall of the liquid storage tube 302 is slidably connected to a moving rod 305, the outer wall of the moving rod 305 is fixedly connected to a pressure plate 306, the inner wall of the support seat 2 is provided with a guide groove 308, and the outer wall of the detector 7 is fixedly connected to a fixed plate 310.

[0033] The above solution is adopted: the purifier box 301 is filled with purifier, which is connected to the liquid storage tube 302 through the connecting tube 307. The purifier will flow into the liquid storage tube 302 through the connecting tube 307 for storage. Since the one-way valve 304 is provided in the liquid outlet 303, the purifier is blocked by the one-way valve 304 and will not flow out of the liquid outlet 303 under normal circumstances; the highest liquid level of the purifier in the liquid storage tube 302 is below the pressure plate 306. When the moving rod 305 and the pressure plate 306 move downward, the pressure plate 306 will squeeze the purifier, causing it to push open the one-way valve. 304, and flows from the liquid outlet 303 to the detection box 5 to mix with water. When the cylinder 6 drives the detector 7 to move downward, the driving assembly can drive the pressing plate 306 to move downward, so that the purifier can be automatically added and stirred during the detection process; the detection head below the detector 7 is inserted into the water and remains fixed. At this time, the pressing plate 306 is above the connecting pipe 307, the liquid outlet 303 and the connection port of the liquid storage pipe 302. The purifier in the purifier box 301 will not flow from the connecting pipe 307 to the top of the pressing plate 306, ensuring that there is no purifier above the pressing plate 306.

[0034] like Figures 2 to 4As shown, the two ends of the connecting tube 307 are fixedly connected to the outer walls of the liquid storage tube 302 and the purification agent box 301 respectively, the liquid storage tube 302 is fixedly connected to the top inner wall of the support base 2, the moving rod 305 passes through the bottom outer wall of the liquid storage tube 302, the pressure plate 306 is slidably connected to the inner wall of the liquid storage tube 302, and the reset spring A309 is fixedly connected to the top inner wall of the support base 2.

[0035] Adopting the above scheme: when water enters the detection box 5, the detector 7 can perform the first detection. At this time, the fixed plate 310 on the outer wall of the detector 7 is below the driving assembly. When the detector 7 moves downward, the fixed plate 310 will not drive the driving assembly and the moving rod 305 and the pressing plate 306 to move downward. At this time, no purifier will be added and the initial water quality will be tested; when the detection is completed and the purifier needs to be added for further testing, the cylinder 6 drives the detector 7 to move up to the top of the driving assembly, and then drives the detector 7 to move downward, so that the detector 7 can drive the driving assembly to move synchronously, so that the moving rod 305 and the pressing plate 306 move downward and the purifier is automatically added to the detection box 5.

[0036] like Figures 4 to 6 As shown, the driving assembly includes a moving block 31, the inner wall of the moving block 31 is elastically connected to the wedge block 33 through an elastic member A32, the inner wall of the wedge block 33 is rotatably connected to the roller 34, the inner wall of the moving block 31 is slidably connected to the sleeve 35, the outer wall of the sleeve 35 is fixedly connected to the guide rod 36, and the inner wall of the sleeve 35 is slidably connected to the slide rod 37.

[0037] Adopting the above solution: Under normal conditions, the moving block 31 is kept in a certain position due to the elastic force of the return spring A309, such as Figure 3As shown, when the detector 7 moves downward, the fixed plate 310 will generate pressure on the wedge block 33, driving the moving block 31 to move downward, stretching the reset spring A309, and the moving block 31 drives the moving rod 305 and the pressure plate 306 to move downward synchronously, so that the purifier can be added to the detection box 5; if the detector 7 is under the moving block 31 in the initial state, that is, the fixed plate 310 does not contact the wedge block 33, the detector 7 will not drive the moving block 31, the moving rod 305 and the pressure plate 306 to move downward when it moves downward; the guide groove 308 is provided with two sections, the upper one is a straight section and the lower one is an oblique section, the guide rod 36 outside the sleeve 35 is always in contact with the inside of the guide groove 308, and when the fixed plate 310 presses the wedge block 33 and drives the moving block 31 to move downward, the guide rod 36 first moves along the straight section of the guide groove 308, and when the moving block 31 moves to the guide rod 36 in the oblique section, the guide rod 36 moves along The inclined part moves, pulling the sleeve 35 and the slide rod 37 to move synchronously. The slide rod 37 drives the wedge block 33 to move toward the inner wall of the moving block 31 and compresses the elastic member A32. Since the roller 34 in the wedge block 33 contacts the fixed plate 310, the roller 34 rotates to reduce friction when the wedge block 33 moves, and the wedge block 33 will gradually lose contact with the fixed plate 310; when the detector 7 moves to the point where the detection head contacts the water added with the purifier in the detection box 5, the guide rod 36 moves to the bottom of the guide groove 308, the wedge block 33 completely loses contact with the fixed plate 310 and resets under the elastic force of the elastic member A32, and the elastic force of the reset spring A309 drives the moving block 31 to move upward and reset, and the moving rod 305 and the pressure plate 306 move upward synchronously. The pressure plate 306 loses the pressure on the purifier in the liquid storage tube 302, stops adding the purifier, and completes an automatic feeding operation.

[0038] like Figures 4 to 6 As shown, the moving block 31 is fixedly connected to the return spring A309, one end of the elastic member A32 is fixedly connected to the outer wall of the wedge block 33, and the other end of the elastic member A32 is fixedly connected to the inner wall of the moving block 31. The wedge block 33 is slidably connected in the inner wall of the moving block 31, and the roller 34 contacts the outer wall of the fixed plate 310; the sliding rod 37 is fixedly connected to the outer wall of the wedge block 33, and the guide rod 36 contacts the inner wall of the guide groove 308.

[0039] The above scheme is adopted: during the process of the detector 7 completing the detection and moving upward, if no purifier needs to be added in the next detection and the initial water quality needs to be tested, the cylinder 6 can drive the detector 7 to keep the fixed plate 310 in a position below the moving block 31 and fixed; if the purifier needs to be added in the next detection, the cylinder 6 can drive the detector 7 to continue to move upward, so that the top of the fixed plate 310 squeezes the arc surface of the wedge block 33, and the wedge block 33 and the slide rod 37 move synchronously into the inner wall of the moving block 31, compressing the elastic part A32. When the fixed plate 310 moves to above the wedge block 33, the wedge block 33 pops out under the elastic force of the elastic part A32 and maintains the position of the detector 7. At this time, if the detector 7 moves downward, it can drive the drive assembly to move synchronously to add purifier to the detection box 5.

[0040] like Figures 7 to 8 As shown, the outer wall of the rotating rod 402 is fixedly connected to the fixed block 403, the inner wall of the fixed block 403 is elastically connected to the partition 405 through the reset spring B404, the inner wall of the fixed block 403 is provided with a groove 406, the inner wall of the fixed block 403 is clamped with a stirring rod 407, the inner wall of the stirring rod 407 is slidably connected to two groups of protrusions 409, and the two groups of protrusions 409 are elastically connected by an elastic member B408.

[0041] By adopting the above scheme, the motor 401 can drive the rotating rod 402 to rotate, and drive the fixed block 403 and the stirring rod 407 connected thereto to rotate, so that the water and the purifier in the detection box 5 can be mixed and stirred to make them uniform; after long-term use, the stirring rod 407 needs to be cleaned. At this time, the stirring rod 407 can be taken out from the fixed block 403 and then installed after cleaning. The installation and disassembly process is relatively convenient and quick, and there is no need to operate by turning bolts, nor is there any need to remove the stirring mechanism 4 as a whole for cleaning, which is more efficient.

[0042] like Figures 7 to 8 As shown, the motor 401 is fixedly connected to the outer wall of the detection box 5, the rotating rod 402 is rotatably connected to the inner wall of the detection box 5, and the stirring rod 407 is in contact with the inner wall of the fixed block 403; one end of the return spring B404 is fixedly connected to the outer wall of the partition 405, and the other end of the return spring B404 is fixedly connected to the inner wall of the fixed block 403, and the partition 405 is slidably connected in the inner wall of the fixed block 403; the stirring rod 407 is in contact with the outer wall of the partition 405, and the two ends of the elastic member B408 are respectively fixedly connected to the outer walls of the two groups of protrusions 409, and the protrusions 409 are engaged with the grooves 406.

[0043] The above solution is adopted: when the stirring rod 407 is fixed in the fixed block 403, the two sets of protrusions 409 are engaged with the groove 406, so that the stirring rod 407 cannot be separated from the fixed block 403, and at this time the stirring rod 407 squeezes the partition 405 and compresses the return spring B404. When the stirring rod 407 needs to be removed, it can be moved into the fixed block 403 to further squeeze the partition 405. The return spring B404 is compressed again. At this time, the inner wall of the groove 406 presses against the protrusion 409. The arc surface is squeezed to move the protrusion 409 into the inner wall of the stirring rod 407 and compress the elastic part B408. When the protrusion 409 is completely out of contact with the groove 406, the stirring rod 407 can be rotated to make the positions of the protrusion 409 and the groove 406 interlaced, and the limit of the stirring rod 407 can be released to remove it; when installing the stirring rod 407, it can be inserted into the fixing block 403, and the fixing can be completed by engaging the protrusion 409 with the groove 406, which is more convenient.

[0044] The working principle and use process of the present invention:

[0045] When conducting water quality testing, the valve on the water pipe between the water supply tank 1 and the test box 5 can be opened, and the water supply tank 1 supplies water to the test box 5. At this time, the cylinder 6 drives the detector 7 to be in a fixed state, and the fixed plate 310 is under the drive assembly. During testing, the cylinder 6 drives the detector 7 to move downward, and the detection head under the detector 7 is inserted into the water in the test box 5 to perform the first initial water quality test. At this stage, the detector 7 and the fixed plate 310 will not drive the drive assembly to move.

[0046] After the first test is completed, it is necessary to add purifier to test different water quality conditions. At this time, the cylinder 6 drives the detector 7 to move up to the top of the drive assembly, and the fixed plate 310 contacts the roller 34 above the wedge block 33, and drives the detector 7 to move downward again through the cylinder 6. The detector 7 presses the wedge block 33 downward through the fixed plate 310, drives the moving block 31 to move downward, stretches the reset spring A309, and the moving block 31 drives the moving rod 305 and the pressure plate 306 to move downward. The pressure plate 306 squeezes the purifier in the liquid storage tube 302, pushes open the one-way valve 304, and the purifier flows from the liquid outlet 303 to the detection box 5, and the purifier is automatically added; the detector 7 drives the drive assembly During the downward movement, the guide rod 36 moves along the oblique segment of the guide groove 308, pulling the sleeve 35 and the slide rod 37 to move the wedge block 33 toward the inner wall of the movable block 31, compressing the elastic part A32, and causing the wedge block 33 to gradually disengage from the fixed plate 310; when the detection head of the detector 7 contacts the water with the purifier, the guide rod 36 reaches the bottom of the guide groove 308, and the wedge block 33 is reset and popped out under the elastic force of the elastic part A32, and the reset spring A309 drives the movable block 31 to move upward and reset, stopping the addition of the purifier. In this way, the purifier can be automatically added to the detection box 5 during the detection process, without the need for manual addition by the operator, reducing the process of manual intervention and having a higher degree of automation.

[0047] During the process of adding the purifier, the motor 401 drives the rotating rod 402 to rotate, driving the stirring rod 407 to rotate to stir the water and the purifier in the detection box 5 to make them mixed evenly, ensuring accurate detection by the detector 7; after the detection is completed, the water in the detection box 5 is discharged from the lower outlet, the cylinder 6 drives the detector 7 to move upward, and the fixed plate 310 is under the driving assembly, ready for the next detection.

[0048] When the stirring rod 407 needs to be cleaned after long-term use, the stirring rod 407 is moved into the fixed block 403, the partition 405 is squeezed to compress the return spring B404, and the inner wall of the groove 406 squeezes the protrusion 409. The protrusion 409 moves to the inner wall of the stirring rod 407 and compresses the elastic part B408. After the protrusion 409 is out of contact with the groove 406, the stirring rod 407 is rotated so that the positions of the protrusion 409 and the groove 406 are staggered, the limit is released, and the stirring rod 407 is taken out for cleaning. After cleaning, the stirring rod 407 is inserted into the fixed block 403 and rotated so that the protrusion 409 is engaged with the groove 406 to complete the installation. There is no need to install and disassemble by turning the bolts multiple times, nor is there any need to take out the stirring mechanism 4 as a whole for cleaning, which is easy to operate.
