Description

Technical Field

[0001] The invention belongs to the technical field of COD sensors, and in particular relates to a device for automatically cleaning electrodes. Background Art

[0002] A COD sensor is a device used to measure the chemical oxygen demand (COD) in water. COD sensors generally use the ultraviolet light absorption method to detect the COD concentration in water. The sensor is generally installed in a drop-in manner. The sensor will be immersed in water for a long time, causing the light source detection component to be contaminated by impurities in the water, thereby affecting the absorption of light, and causing inaccurate measurements. At present, COD sensors that have been immersed in water for a long time need to be cleaned manually on a regular basis. During the cleaning, the sensor needs to be removed from the water, which is inefficient on the one hand and unsafe on the other.

[0003] The published patent with application number 202322999537.0 introduces a sensor with a self-cleaning function, which uses a brush to clean the light emitting and receiving parts of the sensor. This technology can effectively reduce the number of manual cleaning of the sensor. However, for aquatic environments with poor water quality or surrounding sludge and biological activity, the sludge or dirt in the water can easily hang on or adhere to the sensor. The technology disclosed in the patent with application number 202322999537.0 cannot effectively clean the sensor in the above-mentioned aquatic environment.

[0004] The present invention designs a sensor cleaning device which can effectively clean the sensor. At the same time, in order to improve the portability of the cleaning device, a structure combining a micro motor and a gas tank is designed, and the small motor is used to generate high-pressure water to effectively flush the sensor being brushed.

[0005] The present invention designs a device for automatically cleaning electrodes to solve the above problems. Summary of the invention

[0006] Based on this, it is necessary to provide an automatic electrode cleaning device for the problems existing in the current COD sensor cleaning equipment. The first motor in the positioning component, the second motor in the first drive component, the third motor in the flushing component and the fourth motor in the flushing component of the present invention are all small micro motors, which can effectively improve their portability and operational flexibility. The present invention first provides a waterless environment for the COD sensor located in the water and positions the COD sensor through the cooperation of the shell component and the pumping component, and then effectively cleans the ultraviolet emitting part and receiving part of the COD sensor and its vicinity through the cooperation of the scrubbing component, the flushing component and the pumping component, without taking the COD sensor out of the water for cleaning, which effectively improves the cleaning efficiency and cleaning ability of the COD sensor and can effectively improve the safety of the sensor cleaning operation. The scrubbing component and the flushing component in the present invention can perform the operation of first scrubbing and then flushing the sensor surrounded by the shell component to improve the cleanliness of the sensor. The flushing component of the present invention can maintain the water tank in a high-pressure state of being full of water through the connection relationship between the air pump driven by the third motor, the air tank and the water tank, ensuring that the high-pressure water in the water tank reaches the nozzle in the brushing component for a short moment after the brushing component completes the cleaning of the sensor and flushes the sensor that has been effectively brushed, ensuring that the dirt that has been brushed off and still attached to the sensor can be effectively cleaned, thereby ensuring that the sensor can be cleaned.

[0047] The first motor 202 in the positioning assembly 200 of the present invention, the second motor 416 in the first driving assembly 400, the third motor 517 in the flushing assembly 500 and the fourth motor 604 in the flushing assembly are all small micro motors, which can effectively improve their portability and operational flexibility. The present invention first provides a waterless environment for the COD sensor 801 located in the water through the cooperation of the shell assembly 100 and the pumping assembly 600 and positions the COD sensor 801, and then effectively cleans the ultraviolet emitting part and receiving part of the COD sensor 801 and its vicinity through the cooperation of the scrubbing assembly 300, the flushing assembly 500 and the pumping assembly 600, without taking the COD sensor 801 out of the water for cleaning, effectively improving the cleaning efficiency and cleaning ability of the COD sensor 801, and effectively improving the safety of the sensor cleaning operation. The scrubbing assembly 300 and the flushing assembly 500 in the present invention can perform the operation of first scrubbing and then flushing the sensor surrounded by the shell assembly 100, thereby improving the cleanliness of the sensor. The flushing component 500 of the present invention can maintain the water tank 504 in a high-pressure state of being full of water through the connection relationship between the air pump 511 driven by the third motor 517, the air tank 514 and the water tank 504, ensuring that the high-pressure water in the water tank 504 reaches the nozzle 501 in the brushing component 300 for a short moment after the brushing component 300 completes the cleaning of the sensor and flushes the sensor that has been effectively brushed, ensuring that the dirt that has been brushed off and still attached to the sensor can be effectively cleaned, thereby ensuring that the sensor can be cleaned.

[0048] The operation process of the present invention is as follows: In the initial state, the two semicircular shells 101 are in a sealed closed state under the action of the vortex spring 111, the two positioning sleeves 106 are in a closed state, the vortex spring 111 is in a compressed state, the pull rope 703 is in a taut state, the two telescopic rods 209 are in a compressed state and the two positioning forks 213 are in a cross-reacting state, the two second semi-cylinders 310 are just distributed and all located in the corresponding first semi-cylinders 303 and merged to form a complete cylinder, the two first semi-cylinders 303 merge to form a complete cylinder, the four third springs 313 are in a natural state, the six second springs 302 are all in a compressed state, the second ring plate 307 at the bottom of the first semi-cylinder 303 presses against the top plate 207, and the solenoid valve 515 on the second air pipe 509 is in a closed state. Fig.23 As shown, the two scrubbing belts 316 are in a stretched state. There is no water in the water tank 504.

[0049] When the present invention is needed to effectively clean the light emitting and receiving parts of the COD sensor 801 in water, the two semicircular shells 101 are inserted into the water by holding the handle 112 on board and the two semicircular shells 101 are opened by holding the V-shaped rocker 709 .

[0050] The process of opening the two semicircular shells 101 is as follows: hold the upper end of the V-shaped swing rod 709 tightly, and the V-shaped swing rod 709 swings around the hinge point of the remaining hand-grip rod 112, and the lower end of the V-shaped swing rod 709 drives the semicircular shell 101 where the hand-grip rod 112 is located to swing around the first fixing pin 103 relative to the semicircular shell 101 where the hand-grip rod 112 is located through the second rotating sleeve 708, the pull rope 703, the first rotating sleeve 702, the second fixing pin 108 and the fixing arm 107 to open a certain range, such as Fig.10 As shown, the two semicircular shells 101 respectively drive the corresponding positioning forks 213 to open through the corresponding telescopic rods 209. During the opening process of the positioning forks 213, the telescopic rods 209 are extended to the limit under the action of the first spring 211 therein. During the opening process of the two semicircular shells 101, the L tube 705 at the lower end of the guide tube 704 rotates accordingly and the vortex spring 111 is further compressed to store energy. At this point, the opening of the two semicircular shells 101 is completed.

[0051] After the two semicircular shells 101 are fully opened, the handle rod 112 is held by hand to drive the two semicircular shells 101 closer to the COD sensor 801 to be cleaned, so that the COD sensor 801 is located between the two semicircular shells 101, and the lower end of the COD sensor 801 is against the top plate 207. Then, the force on the V-shaped rocker arm 709 is removed, and the two semicircular shells 101 are sealed closed under the resetting action of the vortex spring 111, so that the upper cone of the COD sensor 801 is located between the two positioning sleeves 106 and is limited by the two positioning sleeves 106.

[0052] Before the two semicircular shells 101 enter the water, the distance between the top plate 207 and the top of the semicircular shell 101 is adjusted according to the height size of the COD sensor 801 to be cleaned. The specific operation process is: start the first motor 202, and the first motor 202 drives the top plate 207 on the top rod 206 to move vertically by a certain amplitude through the first gear 203, the second gear 204, and the screw sleeve 205, so that the distance between the top plate 207 and the top of the semicircular shell 101 matches the size of the COD sensor 801 to be cleaned. During the vertical movement of the top plate 207, the first semi-cylinder 303 moves vertically by the same amplitude under the joint action of the second spring 302 and the top plate 207, the first semi-cylinder 303 drives the second semi-cylinder 310 to move vertically by the same amplitude, and the second semi-cylinder 310 drives the scrubbing belt 316 and other structures thereon to move by the same amplitude, so that the scrubbing belt 316 is always located at the appropriate height of the light emitting and receiving parts on the COD sensor 801. During the closing process of the two semicircular shells 101, the positioning forks 213 at the ends of the two telescopic rods 209 gradually adjust the position of the COD sensor 801 to the middle axis of the semicircular shell 101 and finally position the COD sensor 801 to the middle axis. The two telescopic rods 209 are compressed to a certain extent, while the top plate 207 and the positioning sleeves 106 at the top of the two semicircular shells 101 axially position the COD sensor 801. Fig.24 As described above, during the closing process of the two semicircular shells 101, the two scrubbing belts 316 interact with the COD sensor 801 and bend close to the COD sensor 801. During the closing process of the two semicircular shells 101, the light emitting and receiving parts on the COD sensor 801 are adjusted to be opposite to one of the scrubbing belts 316 by rotating the wire on the top of the COD sensor 801 as much as possible to ensure that the scrubbing belt 316 can fully and effectively scrub the light reflecting and receiving parts. At this point, the positioning of the COD sensor 801 in the two semicircular shells 101 is completed, and at this time, the two semicircular shells 101 are filled with water.

[0053] Next, the second motor 416 is started back and forth, and the second motor 416 is driven by the twelfth gear 415, the eleventh gear 414, the tenth gear 413, the fourth shaft 412, the ninth gear 411, the eighth gear 410, and the third shaft 409. The seventh gear 407, the sixth gear 406, the second shaft 405, the first shaft 404, the fifth gear 403, and the second gear ring 418 drive the two second semi-cylinders 310 that are closely attached to each other to reciprocate synchronously in the same direction and with a certain rotation amplitude. The fixed block 312 in the slide groove on each second semi-cylinder 310 will stretch or compress the corresponding third spring 313 to store energy or potential energy. The two second semi-cylinders 310 simultaneously drive the brushing belts 316 on the corresponding three belt rollers 315 to reciprocate synchronously. The two brushing belts 316 that reciprocate synchronously with the two second semi-cylinders 310 scrub the light emitting and receiving parts of the COD sensor 801 and the surrounding areas. At the same time, The fourth gear 401 on the roller shaft 317 corresponding to each second semi-cylinder 310 is driven to rotate under the action of the first gear ring 402, and the fourth gear 401 drives the corresponding belt roller 315 to rotate reciprocatingly through the roller shaft 317. The belt roller 315 drives the corresponding brush belt 316 and the other two belt rollers 315 to rotate, so that the two brush belts 316 are driven by the second semi-cylinder 310 and the belt roller 315 to effectively brush the COD sensor 801, and the movement of the brush belt 316 relative to the second semi-cylinder 310 driven by the belt roller 315 can effectively reduce the wear of the bristles on the brush belt 316, so that all the bristles on the brush belt 316 are involved in the brushing of the COD sensor 801.

[0054] The scrubbing belt 316 can more easily scrub the dirt on the COD sensor 801 under the action of the water enclosed in the two semicircular shells 101, and the dirt scrubbed off the COD sensor 801 enters the water enclosed in the two semicircular shells 101. When the scrubbing belt 316 completes scrubbing of the COD sensor 801, the second motor 416 is stopped, and the second motor 416 drives the two second semi-cylinders 310 to reset through a series of transmissions.

[0055] Next, the fourth motor 604 is started, and the fourth motor 604 drives the water pump 602 to operate. The water pump 602 sucks out the water enclosed in the two semicircular shells 101 and mixed with dirt brushed off the COD sensor 801 through the second water suction pipe 601 and discharges it from the drain pipe 603.

[0056] After the water in the two semicircular shells 101 is pumped out, the third motor 517 is started, and the third motor 517 drives the air pump 511 to operate. The air pump 511 draws air through the air supply pipe 518 and the first air pipe 508. Since the air supply pipe 518 is provided with a resistance valve 516, the air pump 511 preferentially draws air from the water tank 504 through the first air pipe 508, so that a negative pressure is generated in the water tank 504. The air valve 510 on the first air pipe 508 only allows air to pass through but not water, thereby ensuring that the water in the water tank 504 will not enter the air pump 511 through the first air pipe 508. The negative pressure in the water tank 504 causes the external water to fill the water tank 504 through the filter 507, the second one-way valve 506 and the first water suction pipe 505. At the same time, the air pump 511 delivers the air sucked from the first air pipe 508 into the air tank 514 through the third air pipe 512, and the air pressure in the air tank 514 gradually increases. When the air pressure in the air tank 514 reaches a certain value, the solenoid valve 515 is opened, and the high-pressure air in the air tank 514 is pressed into the water tank 504 through the second air pipe 509. Under the pressure of the instantaneous high-pressure air, the water in the water tank 504 reaches the nozzles 501 on both sides of the two second semi-cylinders 310 through the first one-way valve 503 and the high-pressure hose 502, and is sprayed at high speed to the scrubbed part of the COD sensor 801 through the nozzle 501, effectively flushing the dirt still attached to the COD sensor 801 after scrubbing. At the same time, the second motor 416 is reciprocatingly started to drive the two second semi-cylinders 310 to reciprocate, so that the nozzle 501 reciprocates around the COD sensor 801 to spray water columns, so that the scrubbed part of the COD sensor 801 is effectively rinsed and cleaned. At the same time, the fourth motor 604 is started to drive the water pump 602 to pump water from the two semicircular shells 101 to ensure that the dirty water flushed by the nozzle 501 is continuously pumped out. On the one hand, it ensures that the nozzle 501 flushes the COD sensor 801 under resistance, and on the other hand, it ensures that the dirt flushed off the COD sensor 801 by the nozzle 501 is continuously sent out of the semicircular shell 101.

[0057] After the cleaning of the light emitting and receiving parts of the COD sensor 801 is completed, the operation of the second motor 416, the third motor 517 and the fourth motor 604 is stopped and the two second semi-cylinders 310 are reset, and the nozzle 501 stops spraying water to the COD sensor 801. Next, the V-shaped swing rod 709 is held by hand to drive the two semi-circular shells 101 to open, so that the positioning forks 213 at the ends of the two telescopic rods 209 contact the radial positioning of the COD sensor 801, and the hand grip rod 112 is lifted to drive the two semi-circular shells 101 and other structures out of the water, and then, the force on the V-shaped swing rod 709 is removed, so that the two semi-circular shells 101 are closed and reset under the reset action of the vortex spring 111.
