DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] See also Figure 1-5A chemical device with water quality detection comprises a chemical device 1, a side of the chemical device 1 is fixedly installed and connected with a water outlet 2, a bidirectional asynchronous motor 4 is fixedly installed on the side of the chemical device 1, a transmission shaft 19 is fixedly installed on the output shaft of the bidirectional asynchronous motor 4, the transmission shaft 19 is connected with a rotary switch 3 through a first transmission belt 8, the rotary switch 3 passes through the water outlet 2 and is rotatably connected with the water outlet 2, the rotary switch 3 is threadedly connected with a blocking block 7, a processing box 5 is fixedly installed at the bottom of the side of the chemical device 1, a filter plate 6 is elastically connected to the top of the processing box 5 through a damping spring 23, a mounting shell 17 is fixedly installed on the side of the processing box 5 close to the chemical device 1, a slide 18 is fixedly installed inside the mounting shell 17, a display screen 13 is fixedly installed on the side of the chemical device 1, a detection tube 16 is slidably connected to the bottom of the display screen 13, the display screen 13 is electrically connected to the detection tube 16, two clamps 15 are fixedly installed on the side of the detection tube 16, the slide 18 is slidably connected to the detection tube 16 through one of the clamps 15, a mounting column 10 is fixedly installed on the side of the chemical device 1, and the bottom of the mounting column 10 is rotatably connected The rotating shaft 11 is connected to the rotating switch 3 through the second transmission belt 9. A rotating roller 12 is fixedly installed on the outer side of the rotating shaft 11. An arc groove 14 is opened on the side of the rotating roller 12. The arc groove 14 is slidably connected with a clamp 15 on the side away from the slide groove 18. A knob is fixedly installed on the top of the rotating switch 3. The diameter of the rotating switch 3 is consistent with that of the transmission shaft 19 and the rotating shaft 11. Two clamps 15 are symmetrically arranged on both sides of the detection tube 16. The bottom side of the rotating roller 12 is an inclined surface. A downpipe is fixedly installed on the bottom of the processing box 5. The same diameter makes the transmission efficiency of the rotary switch 3, the transmission shaft 19 and the rotating shaft 11 consistent, and the rotation direction is the same. The device turns on the bidirectional asynchronous motor 4 so that when the sewage enters the treatment box 5, the detection tube 16 dips downward, and the water quality detection results are displayed to the observer through the display screen 13. When the sewage reverses and turns on the bidirectional asynchronous motor 4, the detection tube 16 automatically retracts into the installation shell 17, avoiding the detection tube 16 from contacting with the sewage to be treated for a long time, ensuring that its outer side is not corroded by the sewage, and extending the service life of the detection tube 16.

[0025] During use, when the chemical device 1 is used and needs to be drained, the bidirectional asynchronous motor 4 is turned on in the forward direction, so that the output shaft of the bidirectional asynchronous motor 4 drives the transmission shaft 19 to rotate, and the transmission shaft 19 is driven by the first transmission belt 8 to rotate the rotary switch 3. When the rotary switch 3 rotates, the internal block 7 moves upward, and the block 7 is no longer tightly attached to the water outlet of the drain 2, so that the sewage is discharged from the drain 2. The sewage first flows into the filter plate 6, and is initially filtered in the filter plate 6, so that the solid pollutants suspended in the sewage are intercepted above the filter plate 6, and the remaining sewage enters the treatment box 5. When the rotary switch 3 rotates, it is driven by the second transmission belt 9, so that the rotating shaft 11 drives the rotating roller 12 to start rotating. When the rotating roller 12 is in the initial state, the clamp 15 is located at the top of the arc groove 14. As the rotating roller 12 rotates, the clamp 15 gradually moves downward with the arc groove 14 and gradually reaches the lowest end of the arc groove 14. Because the clamp 15 on the other side of the detection tube 16 is slidably connected in the slide groove 18, the position of the detection tube 16 is limited, thereby driving the detection tube 16 to move vertically downward, and the detection head of the detection tube 16 contacts the sewage downward and detects the sewage water quality. The detection result is displayed on the display screen 13, so that the user can directly observe the detection result. After the drainage is completed, the bidirectional asynchronous motor 4 is turned on in the reverse direction, so that the rotating switch 3 drives the block 7 to move vertically upward until the block 7 blocks the outlet of the drain 2. Under the cooperation of the first transmission belt 8 and the second transmission belt 9, the rotating shaft 11 rotates in the opposite direction, thereby driving the rotating roller 12 to rotate in the opposite direction, so that the clamp 15. Gradually moves from the lowest end of the arc groove 14 to the highest end, thereby driving the detection tube 16 to reset.

[0026] Embodiment 2

[0027] See also Figure 6On the basis of the first embodiment, a limit seat 26 is fixedly installed on the inner wall of the mounting shell 17, an extrusion bin 25 is fixedly installed on the top of the limit seat 26, a limit ring 27 is fixedly installed on one end of the limit seat 26 away from the extrusion bin 25, an expansion air bag 28 is glued inside the limit ring 27, a scraping groove 29 is opened on the inner wall of the expansion air bag 28, the expansion air bag 28 is connected with the extrusion bin 25 through a connecting pipe, the expansion air bag 28 is sleeved on the outside of the detection tube 16, the expansion air bag 28 expands and squeezes the detection tube 16 inside the expansion air bag 28 inwardly, at this time, the scraping groove 29 contacts and rubs with the detection tube 16, and the outer wall of the detection tube 16 is scraped. The liquid dipped is scraped off, the extrusion chamber 25 is a deformable structure, the expansion airbag 28 is made of rubber, the top side of the extrusion chamber 25 is in contact with the bottom side of the rotating roller 12 and has no connection, when the rotating roller 12 rotates to a certain angle, it will contact the extrusion chamber 25 and gradually generate a downward extrusion force, the device makes the expansion airbag 28 contact the detection tube 16 during the rotation of the rotating roller 12 through the cooperation between the extrusion chamber 25 and the expansion airbag 28, and scrapes off the liquid at the bottom of the detection tube 16 through the scraping groove 29, so as to avoid the liquid staying on the surface of the detection tube 16 and affecting the next detection result, thereby improving the practicability of the device.

[0028] During use, on the basis of the first embodiment, when the clamp 15 is located at the bottom of the arc groove 14, the detection tube 16 is driven by the clamp 15 to be located at the lowest point. At this time, the detection head of the detection tube 16 contacts the sewage, and the inclined surface on the bottom side of the rotating roller 12 is separated from the upper part of the squeezing chamber 25. The squeezing chamber 25 is not squeezed by the upper part. The detection tube 16 is inside the limit ring 27. Because the squeezing chamber 25 is not squeezed, the gas inside the expansion airbag 28 is connected with the squeezing chamber 25. The expansion airbag 28 is in a relaxed state, allowing the detection tube 16 to slide freely inside the expansion airbag 28. When the rotating roller 12 starts to rotate, , the clamp 15 drives the detection tube 16 to move upward. When the rotating roller 12 rotates to a certain angle, the inclined surface at the bottom of the rotating roller 12 will gradually come into contact with the squeezing chamber 25 and squeeze the squeezing chamber 25. The gas inside the squeezing chamber 25 enters the expansion airbag 28 through the connecting pipe, causing the expansion airbag 28 to expand and squeeze the detection tube 16 inside the expansion airbag 28 inward. At this time, the scraping groove 29 contacts and rubs with the detection tube 16 to scrape off the liquid dipped on the outer wall of the detection tube 16 to prevent the liquid from staying on the surface of the detection tube 16 and affecting the next detection result.

[0029] Embodiment 3

[0030] See also Figure 7On the basis of the first embodiment, a collision block 20 is fixedly installed at the bottom of the transmission shaft 19, a stopper 21 is fixedly installed on the top side of the filter plate 6 close to the transmission shaft 19, a sliding plate 22 is fixedly installed on the side of the filter plate 6, and a fixing seat 24 is fixedly installed on the side of the chemical device 1. The inner wall of the fixing seat 24 is elastically connected to the sliding plate 22 through a spring. During the contact process between the collision block 20 and the stopper 21, the filter plate 6 will be driven to move, and the shock-absorbing spring 23 is used to prevent the displacement of the filter plate 6 from being too violent, so that the filter plate 6 vibrates, and the stopper 24 is fixedly installed on the side of the chemical device 1. 1 is located on the moving track of the impact block 20, and the transmission shaft 19 is rotatably connected with the top of the fixing seat 24, so that the transmission shaft 19 can drive the stopper 21 to rotate stably and periodically contact the impact block 20. Through the mutual cooperation between the impact block 20 and the stopper 21, the device enables the bidirectional asynchronous motor 4 to impact the filter plate 6 through the impact block 20 each time it is used, and causes the filter plate 6 to be slightly displaced, so as to prevent the solid matter on the upper side of the filter plate 6 from being adhered to the surface of the filter plate 6 due to long-term accumulation in the same position, which is conducive to later cleaning.

[0031] During use, on the basis of Example 1, the output shaft of the bidirectional asynchronous motor 4 drives the transmission shaft 19 to rotate, so that the impact block 20 starts to rotate. After the impact block 20 rotates to a certain angle, it contacts the stopper 21. The impact block 20 generates a driving force on the stopper 21 away from the fixed seat 24, so that the filter plate 6 is displaced in the direction away from the fixed seat 24, thereby driving the sliding plate 22 to move inside the fixed seat 24. Because of the stretching of the spring elastic force, the displacement distance of the sliding plate 22 is shorter. After the impact block 20 rotates a certain angle again, it no longer contacts the stopper 21, and the stopper 21 loses the driving force and resets under the stretching action of the spring elastic force. During the contact process between the impact block 20 and the stopper 21, the filter plate 6 will be driven to displace, and the shock-absorbing spring 23 is used to prevent the displacement of the filter plate 6 from being too violent, so that the filter plate 6 vibrates, and the solid matter on the upper side of the filter plate 6 is prevented from being adhered to the surface of the filter plate 6 due to long-term accumulation in the same position.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
