Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device for degrading organic pollutants. Background Art

[0002] In the process of wastewater treatment, biological treatment methods are often used to degrade organic pollutants in wastewater. In wastewater biological treatment, different microorganisms have different pH value adaptation ranges. Since the pH value of wastewater is not only a factor for monitoring the quality of wastewater but also affects the living environment of microorganisms in activated sludge, it is necessary to use a pH meter to measure the pH value of wastewater online.

[0003] Chinese Patent CN 212780764 U discloses a pH measurement and treatment device for chemical wastewater detection, including a box body fixed on a counterweight base. Brake universal wheels are provided at the four corners of the bottom of the counterweight base. A display screen and a control panel are respectively arranged on the front surface of the box body. An electrode placement groove is arranged on the top surface of the box body. A push handle is arranged on the right side surface of the box body. A groove is arranged on the left side surface of the box body, and a lifting mechanism is arranged in the groove. A fixing block is fixed on the lifting mechanism. By setting the lifting mechanism, rotating mechanism, sliding sleeve, fixing bolt and electric telescopic rod, the position and height of the electrode are convenient to adjust, so as to adapt to the measurement requirements in different environments. By setting three sliding sleeves, electrodes are arranged below the three sliding sleeves, and the setting of multiple motors enables the measurement of different liquid levels of chemical wastewater, and the measurement results can be more accurate.

[0004] However, there are still some problems with this technical solution. Since the probe of the pH meter is in direct contact with the wastewater, dirt is easily attached to the probe, and the true pH value of the wastewater cannot be measured in time. Therefore, the measuring electrode needs to be cleaned regularly. In addition, when the pH meter is immersed in acidic or alkaline wastewater for a long time, it is easy to exacerbate the corrosion of the probe by the wastewater and other effects, resulting in the pH meter being unable to maintain a high sensitivity. This will not only affect the service life of the pH meter, but also reduce the accuracy of the monitoring results, which will affect the growth of microorganisms and lead to a reduction in the degradation effect of wastewater organic matter. In actual operation, in order to save costs, the manual operation method is mostly adopted. The pH meter after long-term work is taken out of the wastewater tank for cleaning and maintenance, and a new pH meter is inserted into the wastewater for detection. The operation is cumbersome, and the work efficiency and automation degree are low. The above technical solution has not effectively solved these problems. Summary of the Invention

[0005] The object of the present invention is to provide a wastewater treatment device for degrading organic pollutants in view of the deficiencies of the prior art. By arranging a plurality of detection heads to alternately detect wastewater, the detection heads are prevented from being immersed in the wastewater for a long time, and the detection heads that are not working are cleaned and maintained, and it operates automatically with high working efficiency, solving the problems that the detection heads are easily immersed in the wastewater for a long time, resulting in reduced detection accuracy and service life, and low working efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A wastewater treatment device for degrading organic pollutants includes several detection units for detecting wastewater; it further includes:

[0008] A cleaning part for cleaning the detection unit;

[0009] A maintenance part for maintaining the detection unit; and

[0010] A transfer part for alternately transferring the detection unit between the wastewater and the maintenance part;

[0011] The detection unit includes a detection head;

[0012] The cleaning part includes several scraping plates for scraping and cleaning sundries attached to the detection head;

[0013] The maintenance part includes a maintenance pool filled with a maintenance liquid, and the detection head is immersed in the maintenance liquid for maintenance.

[0014] Specifically, the detection unit can adopt an industrial pH detector, the maintenance liquid can adopt a potassium chloride solution, and the cleaning part, the maintenance part and the transfer part are all arranged above the wastewater;

[0015] A workbench is installed on the tabletop of the wastewater tank, and the detection unit, the cleaning part, the maintenance part and the transfer part are all installed on the workbench, and the detection head passes through the workbench and is immersed in the wastewater to detect the pH of the wastewater;

[0016] By arranging a plurality of detection heads, the detection head of one pH meter is immersed in the wastewater tank for detection work, and the remaining detection heads are immersed in the maintenance pool for maintenance. In order to reduce the use cost, the detection head is preferably two, and the installation method of two detection heads is also described in the specification;

[0017] After a period of time, the transfer department is activated to switch the position of the pH meter, transfer the pH meter in the wastewater to the maintenance pool for maintenance, and at the same time, transfer the pH meter in the maintenance pool to the wastewater pool for continuous detection. In this way, while realizing the continuous on-line detection of wastewater, the pH meter that is not working can be maintained, avoiding the pH meter being soaked in wastewater for a long time, and improving the detection sensitivity and service life of the pH meter.

[0018] As an optimization, the cleaning department includes:

[0019] A support provided above the wastewater;

[0020] A control unit for controlling the closing and opening of the scraper: and

[0021] An outer drive ring rotatably installed in the support;

[0022] The outer drive ring is used to drive the scraper to rotate circumferentially along the probe head;

[0023] The probe head passes through the support and is immersed in the wastewater;

[0024] The scrapers are evenly distributed on the circumferential side of the probe head.

[0025] Specifically, a through hole for the probe head to pass through is provided in the support. In the initial state, the scraper is far from the center of the through hole, so that the probe head can smoothly pass through the through hole;

[0026] When the probe head is taken out of the wastewater upwards, the scraper is activated to deflect, so that the scraper abuts against the outside of the probe head, and then the scraper is activated to rotate around the probe head to scrape off the attachments on the circumferential side of the probe head, completing the cleaning work of the probe head.

[0027] As another optimization, the control unit includes:

[0028] A rotatable inner drive ring;

[0029] A rotating ring for driving the inner drive ring to rotate; and

[0030] A screw member for driving the rotating ring to rotate;

[0031] The rotation of the inner drive ring drives the scraper to deflect;

[0032] Both the scraper and the inner drive ring are provided in the outer drive ring;

[0033] During the movement of the probe head, the screw member drives the rotating ring to rotate.

[0034] Specifically, the inner wall of the inner driving ring is provided with an inner tooth segment meshing with the scraper. After the inner driving ring rotates, all the scrapers are driven to rotate synchronously by meshing transmission, so that the scrapers are against the detection head or away from the detection head;

[0035] The swivel is rotatably mounted inside the support, the screw is movably inserted inside the support, and the screw is provided with an external thread;

[0036] When the screw rod moves up and down, the external thread drives the swivel to rotate.

[0037] As a preferred embodiment, the rotating ring drives the inner driving ring and the outer driving ring to rotate in sequence;

[0038] The rotating ring is provided with a shifting plate for shifting the inner driving ring;

[0039] The rotating ring drives the outer driving ring to rotate through meshing transmission.

[0040] Specifically, a convex rod is provided on the outer side of the inner driving ring, and the shifting plate is used to shift the convex rod; a tooth segment 1 is provided on the outer side wall of the rotating ring, and the tooth segment 1 is staggered with the shifting plate; a tooth segment 2 meshing with the tooth segment 1 is provided on the side wall of the outer driving ring, and the tooth segment 2 is staggered with the convex rod;

[0041] During the rotation of the rotating ring, the inner driving ring is first driven to rotate by the paddle and the convex rod;

[0042] After the inner driving ring rotates, it drives the scraper to deflect, so that the scraper rests on the outer side of the detection head;

[0043] Afterwards, as the rotating ring continues to rotate, the rotating ring drives the outer driving ring to rotate through the tooth segment 1 and the tooth segment 2. During this process, the paddle always presses against the convex rod, so that the inner driving ring and the outer driving ring remain relatively stable. Therefore, the scraper keeps pressing against the detection head and rotates outside the detection head. As the detection head moves upward, the rotating scraper can perform comprehensive scraping and cleaning of the detection head, and the cleaning effect is better.

[0044] The scraper automatically cleans and disperses the detection head, without the need for an additional electric drive device, with a simple structure and low cost of use.

[0045] Furthermore, in order to improve the resetting effect on the inner driving ring and the outer driving ring, resetting springs may be provided on the inner driving ring and the outer driving ring.

[0046] As another preferred embodiment, the screw rod is provided with a one-way plate for one-way transmission with the detection head.

[0047] Specifically, the one-way plate is a one-way rotating structure, the one-way plate in the cleaning part can rotate downward, and the one-way plate is driven to move upward after the detection head moves up; a flange for moving the one-way plate is provided on the outer side of the detection head; the lifting distance of the screw member is not less than the lifting distance of the detection head;

[0048] When the detection head is extracted from the wastewater, the detection head moves from bottom to top; the upwardly moving detection head drives the screw member to move upward through the flange and the one-way plate;

[0049] After the screw rod moves upward, the external thread on the screw rod contacts the rotating ring and drives the rotating ring to rotate, and the rotating ring then drives the scraper to press against the detection head to perform rotational scraping.

[0050] As a preferred embodiment, the transfer unit comprises:

[0051] A guide rail provided between the support and the maintenance pool;

[0052] a plurality of sliding blocks arranged in the guide rail; and

[0053] A plurality of rotating shafts driving the slider to reciprocate inside the guide rail:

[0054] The detection head is arranged on the slider, and a plurality of the sliders drive a plurality of the detection heads to move in an alternating manner.

[0055] Specifically, a support plate is provided on the rotating shaft, and the slider is slidably mounted on the support plate;

[0056] During the rotation of the shaft, the slider and the detection head are driven to move along the guide rail;

[0057] The guide rail is designed so that the moving track of the slider is in a 冂 shape;

[0058] After the slider moves upward and drives the screw member to move upward, the slider turns to horizontal movement to prevent the screw member from being lifted upward excessively;

[0059] After the slider moves horizontally, it is offset from the screw member, and the screw member moves downward and resets under the action of its own gravity. Furthermore, a reset spring can be installed on the screw member.

[0060] As another preferred embodiment, the transfer unit further includes a switching unit for driving the rotating shaft to perform forward and reverse rotation, and the switching unit includes:

[0061] A plurality of sets of driving wheels and driven wheels that rotate in opposite directions; and

[0062] A shifting lever respectively arranged on the driving wheel and the driven wheel;

[0063] The lever is used to drive the rotating shaft to rotate;

[0064] The shift rods on the driving wheel and the driven wheel are staggered.

[0065] Specifically, the driving wheel, the driven wheel and the rotating shaft are all rotatably installed on the workbench. The driving wheel is controlled to rotate by means of a motor or other devices, and the driving wheel drives the driven wheel to rotate synchronously and in the opposite direction. During the rotation of the driving wheel and the driven wheel in the same group, the rotating shaft is driven to rotate reciprocally by the shift rod in sequence, so as to drive the detection head to move back and forth between the wastewater tank and the maintenance tank.

[0066] As a preference, several of the driving wheels are coaxial and fixedly connected to each other.

[0067] Specifically, by setting the driving wheels fixedly connected together, starting the driving wheel can synchronously control the detection heads on all the rotating shafts. By designing the movements of the two switching units, the movement trajectories of the respective detection heads are staggered. After each adjustment, only one detection head is immersed in the wastewater, and the other detection head is immersed in the maintenance tank for maintenance. In this way, by alternating reciprocally, the maintenance of the detection head can be realized while ensuring the continuity of the wastewater detection work. This process can be achieved by a single motor rotating in one direction, with a simple structure and low usage cost.

[0068] As another preference, the maintenance part further includes a sealing plate for sealing the maintenance tank.

[0069] The sealing plate is rotatably installed at the top of the maintenance tank.

[0070] Specifically, each detection unit is equipped with a cleaning part and a maintenance part. When the detection head is immersed in the wastewater for detection, the corresponding maintenance tank is sealed by the sealing plate, so as to protect the maintenance liquid and extend the service life of the maintenance liquid.

[0071] As a preference, during the movement of the detection head towards the maintenance tank, the control unit drives the sealing plate to close and open.

[0072] Specifically, the one-way plate in the maintenance part is a structure that rotates upwards. The one-way plate can also adopt a non-rotatable baffle structure. After the detection head moves downwards, it drives the one-way plate to move downwards together.

[0073] The control unit on the maintenance tank has the same working principle as the control unit in the cleaning part. The sealing plate is rotatably installed in the inner driving ring.

[0074] When the detection head moves from top to bottom above the maintenance pool, the flange on the detection head moves downward through the one-way plate to squeeze the screw member, the screw member drives the swivel to rotate, the swivel drives the inner drive ring to rotate, and the inner drive ring drives the sealing plate to rotate and open, so that the detection head can be extended into the maintenance pool for maintenance. The maintenance pool is opened and closed automatically without the need for an additional electric drive device. The structure is simple and the use cost is low.

[0075] As another preferred embodiment, the transport unit further comprises a positioning member provided on the guide rail for positioning the detection head;

[0076] The top end of the positioning piece is slidably mounted on the guide rail, the bottom of the positioning piece is a telescopic plate which can be telescoped up and down, and the bottom end of the telescopic plate is clamped on the detection head.

[0077] Through this arrangement, the detection head can always maintain a vertical downward posture when moving along the guide rail, so that the detection head can be inserted into the wastewater or curing liquid more stably.

[0078] The beneficial effects of the present invention are:

[0079] (1) The present invention provides a plurality of detection units to perform wastewater detection and maintenance alternately, thereby realizing continuous online detection of wastewater and maintaining the non-operating pH meter, thereby avoiding the pH meter detection head from being immersed in wastewater for a long time, and improving the detection sensitivity and service life of the pH meter.

[0080] (2) The present invention provides a cleaning part. During the process of extracting the detection head from the wastewater, the movement of the detection head is utilized to automatically drive the scraper to press against the detection head and rotate, thereby comprehensively cleaning the detection head, thereby improving the cleanliness of the detection head and ensuring the accuracy of the detection result.

[0081] (3) The present invention provides a sealing plate on the maintenance tank to seal and protect the maintenance liquid. When the detection head is inserted into the maintenance tank, the sealing plate is automatically opened by the movement of the detection head so that the detection head can be smoothly immersed in the maintenance liquid.

[0082] (4) The present invention provides a transfer part, and a single unidirectional rotating motor can drive the detection head to move in an alternating manner, thereby having a simple structure and low use cost.

[0083] To sum up, the present invention has the advantages of replacing and maintaining the detection head under the premise of ensuring continuous detection, and cleaning the detection head extracted from the wastewater, thereby improving the detection accuracy and service life, automatic operation, high working efficiency and automation, and low use cost.

[0093] Embodiment 1

[0094] As Figures 1-3 shown, this embodiment provides a wastewater treatment device for degrading organic pollutants, including several detection units 1 for detecting wastewater; and further including:

[0095] A cleaning unit 2 for cleaning the detection unit 1;

[0096] A maintenance unit 3 for maintaining the detection unit 1; and

[0097] A transfer unit 4 for alternately transferring the detection unit 1 between the wastewater and the maintenance unit 3;

[0098] The detection unit 1 includes a detection head 11;

[0099] The cleaning unit 2 includes a plurality of scraping plates 21 for scraping and cleaning sundries attached to the detection head 11;

[0100] The maintenance unit 3 includes a maintenance pool 31 filled with a maintenance liquid 32, and the detection head 11 is immersed in the maintenance liquid 32 for maintenance.

[0101] Specifically, the detection unit 1 can adopt an industrial pH detector, the maintenance liquid 32 can adopt a potassium chloride solution, and the cleaning unit 2, the maintenance unit 3 and the transfer unit 4 are all arranged above the wastewater;

[0102] A workbench 100 is installed on the tabletop of the wastewater tank. The detection unit 1, the cleaning unit 2, the maintenance unit 3 and the transfer unit 4 are all installed on the workbench 100, and the detection head 11 passes through the workbench 100 and is immersed in the wastewater to detect the pH of the wastewater;

[0103] By providing a plurality of detection heads 11, one detection head 11 of a pH meter is immersed in the wastewater tank for detection work, and the remaining detection heads 11 are immersed in the maintenance pool 31 for maintenance. In order to reduce the use cost, the detection head 11 is preferably two, and the installation method of two detection heads 11 is also described in the specification;

[0104] After a period of time, the transfer unit 4 is started to switch the position of the pH meter, transfer the pH meter in the wastewater to the maintenance pool 31 for maintenance, and at the same time, transfer the pH meter in the maintenance pool 31 to the wastewater tank to continue the detection. In this way, while realizing the continuous on-line detection of the wastewater, the unworking pH meter can be maintained, avoiding the negative impact caused by the pH meter being immersed in the wastewater for a long time, and improving the detection sensitivity and service life of the pH meter.

[0105] As Figures 2-3 shown, further, the cleaning unit 2 includes:

[0106] A support 22 arranged above the wastewater;

[0107] A control unit 23 for controlling the scraping plates 21 to close and open: and

[0108] An outer drive ring 24 rotatably installed in the support 22;

[0109] The outer driving ring 24 is used to drive the scraper 21 to rotate along the circumference of the detection head 11;

[0110] The detection head 11 passes through the support 22 and is immersed in the wastewater;

[0111] The scrapers 21 are evenly distributed around the detection head 11 .

[0112] Specifically, a through hole is provided in the support 22 for the detection head 11 to pass through. In the initial state, the scraper 21 is away from the center of the through hole, so that the detection head 11 can pass through the through hole smoothly.

[0113] When the detection head 11 is taken out of the wastewater, the scraper 21 is started to deflect so that the scraper 21 is against the outside of the detection head 11, and then the scraper 21 is started to rotate around the detection head 11 to scrape off the attachments around the detection head 11, thereby completing the cleaning of the detection head 11.

[0114] like Figures 3-5 As shown, further, the control unit 23 includes:

[0115] a rotatable inner drive ring 231;

[0116] a rotating ring 232 driving the inner driving ring 231 to rotate; and

[0117] A screw member 233 driving the rotating ring 232 to rotate;

[0118] The rotation of the inner driving ring 231 drives the scraper 21 to deflect;

[0119] The scraper 21 and the inner driving ring 231 are both arranged inside the outer driving ring 24;

[0120] During the movement of the detection head 11 , the screw member 233 drives the rotating ring 232 to rotate.

[0121] Specifically, the inner wall of the inner driving ring 231 is provided with an inner tooth segment 2311 meshing with the scraper 21. After the inner driving ring 231 rotates, all the scrapers 21 are driven to rotate synchronously by meshing transmission, so that the scrapers 21 are against the detection head 11 or away from the detection head 11;

[0122] The swivel ring 232 is rotatably mounted inside the support 22, and the screw member 233 is movably inserted inside the support 22, and the screw member 233 is provided with an external thread;

[0123] When the screw member 233 moves up and down, the external thread drives the rotating ring 232 to rotate.

[0124] likeFigures 4-5 As shown, further, the rotating ring 232 drives the inner driving ring 231 and the outer driving ring 24 to rotate in sequence;

[0125] The rotating ring 232 is provided with a dial plate 2321 for dialing the inner driving ring 231;

[0126] The rotating ring 232 drives the outer driving ring 24 to rotate through meshing transmission.

[0127] Specifically, a convex rod 2312 is provided on the outer side of the inner driving ring 231, and a dial plate 2321 is used to dial the convex rod 2312; a tooth segment 1 2322 is provided on the outer side wall of the rotating ring 232, and the tooth segment 1 2322 and the dial plate 2321 are staggered and distributed; a tooth segment 241 meshing with the tooth segment 1 2322 is provided on the side wall of the outer driving ring 24, and the tooth segment 241 and the convex rod 2312 are staggered;

[0128] During the rotation of the rotating ring 232, the inner driving ring 231 is first driven to rotate by the dial plate 2321 and the protruding rod 2312;

[0129] After the inner driving ring 231 rotates, the scraper 21 is driven to deflect, so that the scraper 21 abuts against the outer side of the detection head 11;

[0130] Afterwards, as the rotating ring 232 continues to rotate, the rotating ring 232 drives the outer driving ring 24 to rotate through the tooth segment 1 2322 and the tooth segment 241. During this process, the paddle 2321 always presses against the convex rod 2312, so that the inner driving ring 231 and the outer driving ring 24 remain relatively stable. Therefore, the scraper 21 keeps pressing against the detection head 11 and rotates outside the detection head 11. As the detection head 11 moves upward, the rotating scraper 21 can perform comprehensive scraping and cleaning of the detection head 11, and the cleaning effect is better.

[0131] The scraper 21 automatically cleans and disperses the detection head 11, without the need for an additional electric drive device, with a simple structure and low cost.

[0132] Furthermore, in order to improve the resetting effect on the inner driving ring 231 and the outer driving ring 24 , resetting springs may be provided on the inner driving ring 231 and the outer driving ring 24 .

[0133] like Figure 5 As shown, further, a one-way plate 2331 is provided on the screw member 233 for one-way transmission with the detection head 11 .

[0134] Specifically, the one-way plate 2331 is a one-way rotating structure. The one-way plate 2331 in the cleaning part 2 can rotate downward, and the one-way plate 2331 is driven to move upward after the detection head 11 moves upward. A flange 12 for moving the one-way plate 2331 is provided on the outer side of the detection head 11. The lifting distance of the screw member 233 is not less than the lifting distance of the detection head 11.

[0135] When the detection head 11 is extracted from the wastewater, the detection head 11 moves from bottom to top; the upwardly moving detection head 11 drives the screw member 233 to move upward through the flange 12 and the one-way plate 2331;

[0136] After the screw member 233 moves upward, the external thread on the screw member 233 contacts the rotating ring 232 and drives the rotating ring 232 to rotate, and the rotating ring 232 drives the scraper 21 to press against the detection head 11 to perform rotational scraping.

[0137] like Figures 2-6 As shown, further, the transfer unit 4 includes:

[0138] A guide rail 41 provided between the support 22 and the maintenance tank 31;

[0139] A plurality of sliders 42 disposed in the guide rail 41; and

[0140] A plurality of rotating shafts 43 driving the slider 42 to reciprocate inside the guide rail 41:

[0141] The detection heads 11 are arranged on the sliders 42 , and a plurality of the sliders 42 drive a plurality of the detection heads 11 to move alternately.

[0142] Specifically, a support plate 431 is provided on the rotating shaft 43, and the slider 42 is slidably mounted on the support plate 431;

[0143] During the rotation of the rotating shaft 43, the slider 42 and the detection head 11 are driven to move along the guide rail 41;

[0144] The guide rail 41 is designed so that the moving track of the slider 42 is in a 冂-shaped shape;

[0145] After the slider 42 moves upward and drives the screw member 233 to move upward, the slider 42 turns to horizontal movement, which can prevent the screw member 233 from being excessively lifted upward;

[0146] After the slider 42 moves horizontally, it is offset from the screw member 233 , and the screw member 233 moves downward and resets under the action of its own gravity. Furthermore, a reset spring can be installed on the screw member 233 .

[0147] like Figure 6 As shown, further, the transfer part 4 also includes a switching unit 44 for driving the rotating shaft 43 to rotate forward and reversely, and the switching unit 44 includes:

[0148] A number of driving wheels 441 and driven wheels 442 that rotate in reverse; and

[0149] Poking rods 443 respectively arranged on the driving wheel 441 and the driven wheel 442;

[0150] The poking rod 443 is used to drive the rotating shaft 43 to rotate;

[0151] The poking rods 443 on the driving wheel 441 and the driven wheel 442 are staggered.

[0152] Specifically, the driving wheel 441, the driven wheel 442 and the rotating shaft 43 are all rotatably installed on the workbench 100. The driving wheel 441 is controlled to rotate by means of a motor or other devices, and the driving wheel 441 drives the driven wheel 442 to rotate synchronously in the reverse direction; during the rotation of the driving wheel 441 and the driven wheel 442 in the same group, the rotating shaft 43 is driven to rotate reciprocally through the poking rod 443 in sequence, so as to drive the detection head 11 to move back and forth between the wastewater tank and the maintenance tank 31;

[0153] Such as Figure 6 shown, further, a number of the driving wheels 441 are coaxial, and a number of the driving wheels 441 are fixedly connected.

[0154] Specifically, by setting the driving wheels 441 to be fixedly connected together, starting the driving wheels 441 can synchronously control the detection heads 11 on all the rotating shafts 43; by designing the movement of the two switching units 44, the movement trajectories of the respective detection heads 11 are staggered. After each adjustment, only one detection head 11 is immersed in the wastewater, and the other detection head 11 is immersed in the maintenance tank 31 for maintenance. In this way, by alternating reciprocally, while the detection head 11 is being maintained, the continuity of the wastewater detection work can be ensured. This process can be achieved by a single unidirectional rotating motor, with a simple structure and low usage cost. In addition, by starting the motor regularly, automated work can be realized, improving work efficiency.

[0156] Such as Figure 7 shown, among which the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 2 and Embodiment 1 lies in:

[0157] In this embodiment, the maintenance part 3 further includes a sealing plate 33 for sealing the maintenance tank 31;

[0158] The sealing plate 33 is rotatably installed at the top of the maintenance tank 31.

[0159] Specifically, a cleaning unit 2 and a maintenance unit 3 are configured on each detection unit 1. When the detection head 11 is immersed in the wastewater for detection, the corresponding maintenance pool 31 is sealed by a sealing plate 33, thereby protecting the maintenance liquid 32 and extending the service life of the maintenance liquid 32.

[0160] As Figure 7 shown, furthermore, during the process of the detection head 11 moving towards the maintenance pool 31, the control unit 23 drives the sealing plate 33 to close and open.

[0161] Specifically, the one-way plate 2331 in the maintenance unit 3 is a structure that rotates upward. The one-way plate 2331 can also adopt a non-rotatable baffle structure. After the detection head 11 moves downward, it drives the one-way plate 2331 to move downward together;

[0162] The control unit 23 on the maintenance pool 31 has the same working principle as the control unit 23 in the cleaning unit 2. The sealing plate 33 is rotatably installed in the inner drive ring 231;

[0163] When the detection head 11 moves downward from above to the maintenance pool 31, the flange 12 on the detection head 11 squeezes the screw member 233 downward through the one-way plate 2331. The screw member 233 drives the rotating ring 232 to rotate, the rotating ring 232 drives the inner drive ring 231 to rotate, and the inner drive ring 231 drives the sealing plate 33 to rotate and open, so that the detection head 11 can extend into the maintenance pool 31 for maintenance. The opening and closing of the maintenance pool 31 are automatically performed without the need to additionally set up a power driving device, with a simple structure and low use cost.

[0164] Embodiment Three

[0165] As Figure 3 shown, among them, the same or corresponding components as those in Embodiment Two adopt the corresponding reference numerals in Embodiment Two. For the sake of simplicity, only the differences from Embodiment Two will be described below. The differences between this Embodiment Three and Embodiment Two are as follows:

[0166] In this embodiment, the transfer unit 4 further includes a positioning member 45 provided on the guide rail 41 for positioning the detection head 11;

[0167] The top end of the positioning member 45 is slidably installed on the guide rail 41, and the bottom of the positioning member 45 is a telescopic plate that can be telescoped up and down, and the bottom end of the telescopic plate is clamped on the detection head 11.

[0168] Through this setting, during the process of the detection head 11 moving along the guide rail 41, the detection head 11 can always maintain a vertical downward posture, so that the detection head 11 can be inserted into the wastewater or the maintenance liquid 32 more stably.

[0169] Working Steps

[0170] Step 1: In the initial state, a detection head 11 is immersed in the wastewater tank for detection, and the corresponding maintenance tank 31 is in a sealed state; the other detection head 11 is immersed in the maintenance tank 31 for maintenance and standby.

[0171] Step 2: When switching the states of the two detection heads 11, start the rotation of the driving wheel 441, and the driving wheel 441 drives the driven wheel 442 to rotate synchronously and in the opposite direction.

[0172] Step 3: During the rotation of the driving wheel 441 and the driven wheel 442, the rotating shaft 43 is driven to reciprocate by the lever 443 in sequence, and the moving directions of the two groups of rotating shafts 43 are opposite.

[0173] Step 4: The rotating shaft 43 drives the detection head 11 to move in the cabinet through the slider 42.

[0174] Step 5: When the detection head 11 in the support 22 moves upward and is withdrawn from the wastewater, the detection head 11 drives the screw member 233 to move upward through the flange 12.

[0175] Step 6: The upward-moving screw member 233 drives the rotating ring 232 to rotate.

[0176] Step 7: First, the rotating ring 232 drives the inner drive ring 231 to rotate through the dial plate 2321 and the convex rod 2312, and the inner drive ring 231 drives the scraper 21 to deflect and abut against the outside of the detection head 11.

[0177] After that, the rotating ring 232 drives the outer drive ring 24 to rotate through the first tooth section 2322 and the second tooth section 241, and the outer drive ring 24 drives the scraper 21 to rotate and scrape on the outside of the detection head 11.

[0178] Step 8: After the detection head 11 moves upward and then moves to the right, it separates from the screw member 233 on the support 22, and the control unit 23 on the support 22 automatically resets.

[0179] Step 9: The detection head 11 moves downward along the guide rail 41 towards the maintenance tank 31.

[0180] Step 10: The downward-moving detection head 11 drives the screw member 233 on the maintenance tank 31 to move, so that the maintenance tank 31 is opened.

[0181] Step 10: The detection head 11 is immersed in the maintenance tank 31 for maintenance.

[0182] Step 11: Similarly, the detection head 11 originally in the maintenance tank 31 simultaneously moves in the opposite direction to the wastewater tank for detection work.

[0183] Step 12: Repeat Steps 2 to 11, and the two detection heads 11 alternately perform detection and maintenance.

[0184] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
