Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to a probe cleaning device for online monitoring of wastewater. Background Art

[0002] Water is an important resource that is indispensable in human production and life. A large amount of wastewater is generated during industrial production. Therefore, it is necessary to monitor the wastewater online to meet the discharge requirements.

[0003] Application number CN202122910904.6 discloses a fully automatic cleaning device for the probe of an online monitoring device for wastewater treatment, comprising: a first track and a second track, a first long groove penetrating the first track is provided in the middle of the first track, a second long groove penetrating the second track is provided in the middle of the second track, a conduit is relatively slidably arranged in the first groove, the conduit is also relatively slidably arranged in the second groove, and a first baffle and a second baffle are arranged at both ends of the conduit. A movable conduit is arranged on the first track and the second track, and a nozzle is arranged on the conduit;

[0004] When the above patent structure is in use, the nozzle is mainly driven to move by the first track and the second track, and can only flush the probe surface that leaves the water surface. However, the first track and the second track can only drive the nozzle to move along the outermost diameter of the probe, and can only drive the nozzle to move in the left and right direction, or the front and back direction. Therefore, only the left and right direction, or one side surface of the front and back direction of the probe can be cleaned by the nozzle, which is inconvenient to clean different positions of the probe surface. The cleaning range is limited, and the probe surface is only cleaned by flushing it, which easily leaves stuck impurities on the probe surface, and the stuck impurities are difficult to flush away. Therefore, the probe surface is not cleaned thoroughly enough, reducing the accuracy of the probe monitoring. Summary of the invention

When the outer and inner slide plates rotate, the inner water outlet valve on the inner slide plate can spray water to clean different positions on the surface of the detection arc surface, and the brush on the inner slide plate can scrape different positions on the surface of the detection arc surface.

[0021] 3. After the water spray cleaning is completed, the drying fan can deliver hot air to the external drying valves on both sides of the inner slide through the drying hose. Therefore, the surface of the detection arc surface after cleaning can be dried through the external drying valve, so that the detection arc surface of the probe body can be cleaned more efficiently and thoroughly.

Figure 2As shown, the cleaning pump 101 can transport clean water to the inside of the inner water outlet valve 508 through the cleaning hose 106, so that the surface of the detection arc 201 can be cleaned through the inner water outlet valve 508, and the drying fan 103 can transport hot air to the inside of the outer drying valve 509 through the drying hose 107, so that the surface of the detection arc 201 can be dried through the outer drying valve 509.

[0034] In this embodiment, a gap is left between the outlet pipe 104 and the inner wall of the open ring 105, the inner end of the chain 108 is fixedly connected to the open ring 105, the cleaning hose 106 and the drying hose 107 are rotatably connected to the chain pin on the chain 108, and the inner slide plate 506 slides on the upper fixed rod 501 and drives the chain 108 to swing;

[0036] In this embodiment, the external scraping structure 3 is located outside the cleaning pump 101 and the drying fan 103, and the external scraping structure 3 includes a rotating groove 301 and a rotating ring 302, and the rotating groove 301 is opened on the bottom surface of the barrel 1, and the rotating ring 302 is rotatably connected to the inside of the rotating groove 301. The inner bottom surface of the barrel 1 and the inner side of the rotating groove 301 are installed with a No. 1 motor 303, and the output end of the No. 1 motor 303 is fixed with a driving toothed disc 304, and the rotating ring 302 is fixed with a toothed ring 305 meshing with the driving toothed disc 304. The rotating ring 30 2 is located inside the barrel 1 and is equipped with a second motor 306 through a bracket. A winding roller 307 is fixed to the output end of the second motor 306. A rotating drum 308 is rotated on the end surface of the rotating ring 302 and is located below the winding roller 307. A screw sleeve 309 for fixing the rotating drum 308 is threadedly connected to the surface of the rotating drum 308. A long rectangular water-absorbing cloth strip 310 is fixed on the winding roller 307. A smooth surface 311 is provided on one side of the water-absorbing cloth strip 310, and a rough surface 312 is provided on the other side.

[0037] For details, please refer to the attached manual. Figure 3As shown, starting the No. 1 motor 303 can drive the rotating ring 302 to rotate by driving the engagement of the gear disc 304 and the gear ring 305. When the rotating ring 302 rotates, the outer slide plate 502 and the inner slide plate 506 can be driven to rotate, and the absorbent cloth strip 310 can also be driven to rotate. The cleaning hose 106 and the drying hose 107 can be driven to rotate through the chain 108, so the cleaning hose 106 and the drying hose 107 will not interfere with the cleaning pump 101 and the drying fan 103. When the outer slide plate 502 and the inner slide plate 506 rotate, different positions on the surface of the detection arc surface 201 can be scraped by the brush 504, and different positions on the surface of the detection arc surface 201 can be cleaned and dried by the inner water outlet valve 508 and the outer drying valve 509.

[0038] In this embodiment, one end of the absorbent strip 310 is fixedly connected to the winding roller 307, and the other end of the absorbent strip 310 passes through the rotating drum 308 and extends to the outside of the barrel 1. The screw sleeve 309 is located below the barrel 1 and contacts the bottom surface of the barrel 1.

[0039] Specifically, the absorbent cloth strip 310 can be driven to rotate by rotating the rotating drum 308, so the contact surfaces of the smooth surface 311 and the rough surface 312 with the detection arc surface 201 can be adjusted, and the screw sleeve 309 can be rotated to make it press against the barrel 1, and the rotating drum 308 can be fixed to the barrel 1 by the friction force with the barrel 1, so the contact surfaces of the smooth surface 311 and the rough surface 312 with the detection arc surface 201 can be determined, and when the smooth surface 311 contacts the detection arc surface 201, impurities with low adhesion on the detection arc surface 201 can be scraped off during the movement of the absorbent cloth strip 310, and when the rough surface 312 contacts the detection arc surface 201, impurities with high adhesion on the detection arc surface 201 can be scraped off during the movement of the absorbent cloth strip 310. In addition, the winding roller 307 can lengthen or wind up the absorbent cloth strip 310, so it can The length of the absorbent cloth strip 310 extending out of the barrel 1 is adjusted. When the winding roller 307 does not rotate, the length of the absorbent cloth strip 310 extending out of the barrel 1 is fixed, and the screw sleeve 309 is threadedly connected to the rotating drum 308. By rotating the screw sleeve 309 to make it press against the rotating ring 302, the rotating drum 308 can be fixedly connected to the rotating ring 302 through the friction between the movable screw sleeve 309 and the rotating ring 302, so that the rotating drum 308 plays a role in supporting and guiding the absorbent cloth strip 310, so that when the rotating ring 302 rotates, the absorbent cloth strip 310 can be driven to revolve around the probe body 2 through the rotating drum 308, and the rotating drum 308 does not rotate on its own, and the rotating drum 308 is at a certain distance from the probe body 2. Therefore, when the absorbent cloth strip 310 is stationary, it is vertically downward, so that the part of the absorbent cloth strip 310 extending out of the barrel 1 can be prevented from contacting the probe body 2.

[0040] In this embodiment, the support 4 is fixed on the rotating ring 302, a third motor 401 is installed on the outer side of the support 4, an outer gear plate 402 is fixed to the output end of the third motor 401, an inner bracket 403 is fixed to the inner side of the support 4, a differential structure 404 is installed on the inner bracket 403, and an inner gear plate 405 is fixed to the differential structure 404;

[0041] For details, please refer to the attached manual. Figure 6 As shown, when the third motor 401 is started and drives the outer gear disc 402 and the inner gear disc 405 to rotate, the outer slide plate 502 can be driven to move through the engagement of the outer gear disc 402 with the outer tooth groove 503, and the inner slide plate 506 can be driven to move through the engagement of the inner gear disc 405 with the inner tooth groove 507.

[0042] In this embodiment, one end of the differential structure 404 is fixedly connected to the outer gear plate 402, and the other end of the differential structure 404 is fixedly connected to the inner gear plate 405;

[0043] Specifically, the differential structure 404 can be used to make the outer gear disc 402 and the inner gear disc 405 rotate at different speeds, and the rotation speed of the inner gear disc 405 is greater than the rotation speed of the outer gear disc 402. Therefore, when the outer gear disc 402 and the inner gear disc 405 rotate at the same time, the outer slide plate 502 and the inner slide plate 506 can move downward at the same time, and the inner slide plate 506 can be moved out of the outer slide plate 502 to its outside. When the outer gear disc 402 and the inner gear disc 405 are reversed at the same time, the outer slide plate 502 and the inner slide plate 506 can be moved upward at the same time, so that different positions on the surface of the detection arc 201 can be cleaned subsequently.

[0044] In this embodiment, the cleaning structure 5 includes an upper fixed rod 501, a circular ring is fixed on the top of the upper fixed rod 501, and the circular ring is rotatably connected to the inner top surface of the barrel 1, an outer slide plate 502 is slidably provided at the bottom end of the upper fixed rod 501, an outer surface of the outer slide plate 502 is provided with an outer tooth groove 503 meshing with the outer toothed disc 402, a brush 504 is fixedly provided on the inner surface of the outer slide plate 502, an inner slide groove 505 is provided inside the outer slide plate 502, an inner slide plate 506 is slid inside the inner slide groove 505, an inner surface of the inner slide plate 506 is provided with an inner tooth groove 507 meshing with the inner toothed disc 405, an inner water outlet valve 508 is fixed to the middle of the inner surface of the inner slide plate 506, and outer drying valves 509 are fixed to both sides of the inner surface of the inner slide plate 506;

[0045] For details, please refer to the attached manual. Figure 6As shown, when the outer slide plate 502 and the inner slide plate 506 move downward, the brush 504 arranged on the outer slide plate 502 can be used to scrape different positions on the surface of the detection arc surface 201 so as to scrape off impurities adhered to the detection arc surface 201, and the inner slide plate 506 can drive the inner water outlet valve 508 and the outer drying valve 509 on its inner surface to move, so that different positions of the detection arc surface 201 can be cleaned through the inner water outlet valve 508, and the cleaned detection arc surface 201 can be quickly dried through the outer drying valve 509, so that the probe body 2 can be quickly put into use.

[0046] In this embodiment, the outer slide 502 and the inner slide 506 form an arc-shaped telescopic plate, and the curvature of the arc-shaped telescopic plate is the same as the curvature of the probe body 2, the brush 504 is in contact with the probe body 2, and multiple groups of internal water outlet valves 508 are arranged along the arc direction of the inner slide 506, and the multiple groups of internal water outlet valves 508 are connected through a conduit arranged in the middle of the inner slide 506, and the outer end of the cleaning hose 106 is connected to the conduit therein, and multiple groups of external drying valves 509 are arranged along the arc direction of the inner slide 506, and the multiple groups of external drying valves 509 are connected through conduits arranged on both sides of the inner slide 506, and the drying hose 107 is connected to the conduit therein, and the outer ends of the chains 108 on the cleaning hose 106 and the drying hose 107 are fixedly connected to the inner slide 506;

[0047] Specifically, through the arc-shaped telescopic plate composed of the outer slide plate 502 and the inner slide plate 506, the brush 504, the inner water outlet valve 508 and the outer drying valve 509 can be moved to different positions on the surface of the detection arc surface 201, so as to clean different positions on the surface of the detection arc surface 201, and when the arc-shaped telescopic plate composed of the outer slide plate 502 and the inner slide plate 506 is extended or contracted, the cleaning hose 106 and the drying hose 107 can be driven to move up and down. At this time, the chain 108 on the cleaning hose 106 and the drying hose 107 can follow its up and down movement, and the inner slide plate 506 can drive the cleaning hose 106, the drying hose 107 and the open ring 105 to rotate around the cleaning pump 101 and the drying fan 103 through the chain 108.

[0048] The working principle and use process of the present invention are as follows: by connecting the barrel 1 with the external lifting structure, the barrel 1 can be driven to move up and down, and the wastewater can be monitored through the detection arc surface 201. When the barrel 1 drives the probe body 2 to move downward and the bottom end part of the detection arc surface 201 is extended into the water to monitor the wastewater, the upper end part of the detection arc surface 201 is located above the wastewater liquid level, and the rotating ring 302 is stationary. At this time, the rotating ring 302 does not drive the absorbent cloth strip 310 to rotate, and the absorbent cloth strip 310 is stationary and vertically downward, and the bottom end part of the detection arc surface 201 is located below the wastewater liquid level, and the bottom end part of the absorbent cloth strip 310 is also located below the wastewater liquid level. At this time, the bottom end part of the absorbent cloth strip 310 is soaked and the weight becomes larger, and the absorbent cloth strip 310 has no effect on the detection. The arc surface 201 is cleaned. When the surface of the detection arc surface 201 needs to be cleaned, the part of the absorbent cloth strip 310 extending outside the barrel 1 is lengthened to a suitable length, and the No. 1 motor 303 is started to drive the driving gear disc 304 to rotate, and the driving gear disc 304 can drive the rotating ring 302 to rotate by engaging with the gear ring 305. The rotating ring 302 drives the absorbent cloth strip 310 to revolve around the probe body 2 through the rotating drum 308, and the rotating drum 308 does not rotate by itself. Since the bottom end part of the absorbent cloth strip 310 is soaked and the weight becomes larger, and the wastewater has a certain resistance to the bottom end of the absorbent cloth strip 310, at this time, by adjusting the No. 1 motor 303 to a suitable speed, when the rotating ring 302 drives the absorbent cloth strip 310 to rotate, the absorbent cloth strip 310 can be located at the wastewater liquid surface. The above part can rotate first, and the part of the absorbent strip 310 located below the wastewater surface rotates next, that is, the part of the absorbent strip 310 located above the wastewater surface drives the part of the absorbent strip 310 located below the wastewater surface to rotate. At this time, the part of the absorbent strip 310 located above the wastewater surface can generate a certain pulling force on the part of the absorbent strip 310 located below the wastewater surface, and the part of the absorbent strip 310 located below the wastewater surface will not leave the wastewater due to the centrifugal effect. Therefore, the absorbent strip 310 can move in a spiral shape, and in the process of the swivel 302 driving the absorbent strip 310 to revolve around the probe body 2, the absorbent strip 310 can slide closely on the surface of the detection arc surface 201, so through the absorbent strip 310 The excess impurities on the detection arc surface 201 can be scraped and cleaned. When the probe body 2 leaves the water surface and the detection arc surface 201 needs to be cleaned, starting the No. 3 motor 401 can drive the outer gear disc 402 and the inner gear disc 405 to rotate, and the differential structure 404 can make the rotation speed of the inner gear disc 405 greater than the rotation speed of the outer gear disc 402. When the outer gear disc 402 rotates, it can drive the outer slide plate 502 to slide downward through the engagement with the outer tooth groove 503. At this time, the upper fixed rod 501 can guide the outer slide plate 502.
