These wastewaters will contain a large number of pollutants such as lead, mercury, cadmium, and chromium. Wastewater containing these pollutants is called a complex pollution source. In order to detect whether these pollutants exceed the standard at any time, they need to be tested.

[0017] According to the inner diameter of the sewage pipe, the distance between each set of side sampling mechanisms and the central axis of the turntable is adjusted until the outer wall of the side sampling mechanism can fit with the inner wall of the sewage pipe;

[0018] Start each group of electric push rods, and each group of electric push rods pushes each group of motor installation boxes to extend obliquely to the side away from the second detection box until each group of moving wheels fits against the inner wall of the sewage pipe;

[0019] Start each set of second waterproof motors, and the second waterproof motors drive each set of moving wheels to rotate, so that the entire device can move forward in the pipeline;

[0025] The beneficial effects of the present invention are:

[0026] 1. The mobile unit drives the entire device to move in the sewage pipe, so as to meet the requirements of point sampling without disassembling the pipe. And while moving, the turntable is used to drive each set of side sampling mechanisms to rotate. And the position of each set of side sampling mechanisms can be adjusted according to the inner diameter of the sewage pipe, so that it can always slide and fit with the inner wall of the sewage pipe. Not only can the central water intake pipe be used to extract industrial wastewater samples, but also the sludge on the inner wall of the sewage pipe can be collected as samples by rotating the side sampling mechanism, thereby enriching the functionality of the device and ensuring the diversity of sample collection by using its movable characteristics.

[0027] 2. As the device moves forward, each group of anti-sludge skid plates rolls and fits against the inner wall of the sewage pipe. Since the anti-sludge skid plates are V-shaped, they can break the sludge on the inner wall to both sides when in contact with the inner wall of the sewage pipe, thus avoiding the slipping of the moving wheels when the device moves forward and improving the smoothness and stability of the device when moving forward. And when the device needs to perform fixed-point sampling, it only needs to control the electric push rod to push the moving wheels to continue squeezing the inner wall of the sewage pipe, thereby fixing the entire device. This improves the compatibility of the device.

[0028] 3. When collecting sludge samples, the side sampling mechanism scrapes off the sludge through a spiral scraper. Due to its spiral structure and winding around the sampling tube, the sludge will not accumulate on a certain point on the surface of the sampling tube after being scraped off by the spiral scraper, but will be arranged in sequence along its spiral path and finally enter the sampling tube cavity through the sampling port, thus avoiding sludge clogging the sampling port, which not only improves the fluency of the sampling work, but also improves the convenience of subsequent cleaning of the device.

[0029] 4. After the wastewater sample or sludge sample enters the intermediate water pipe, it is injected into each group of first water quality measuring instruments through the first water inlet, and each group of first water quality measuring instruments performs separate measurements at the same time. When one or more groups of first water quality measuring instruments detect abnormal samples, the second water quality measuring instrument is started, and the wastewater in the sewage pipe is introduced into the second water quality measuring instrument through the secondary sampling tube through the liquid pump for secondary detection. This ensures the accuracy of the detection.

Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0045] The embodiment of the present invention provides a testing device for composite pollution sources in industrial clusters, including a sampling unit 100. For example, Figure 1 As shown, a primary detection unit 200 is installed on one side of the sampling unit 100 away from the input end. The power output part of the primary detection unit 200 is transmission-connected with the sampling unit 100. The sampling unit 100 is used to extract industrial wastewater samples in the sewage pipe. The primary detection unit 200 is used to detect the wastewater samples.

[0046] A secondary detection unit 300 is installed on one side of the primary detection unit 200 away from the sampling unit 100. The secondary detection unit 300 is used to perform secondary detection on the wastewater sample.

[0047] A plurality of groups of mobile units 400 are distributed in a circular array around the central axis of the secondary detection unit 300, and one end of the mobile unit 400 extends to the outside of the secondary detection unit 300. The mobile unit 400 is used to help the device as a whole move in the pipeline.

[0048] The sampling unit 100 includes a rotating disk 110. For example, Figure 2 , Figure 3 and Figure 4 As shown, a central water inlet pipe 120 is installed at the center of one side wall of the rotating disk 110, and a plurality of groups of slide grooves 111 are distributed in a circular array at the edges of the rotating disk 110. The slide groove 111 is slidably connected to a slider 113, and a group of waterproof pleated cloths 114 are provided on both sides of the slider 113. The other ends of the two groups of waterproof pleated cloths 114 are respectively installed on the inner walls of the two ends of the slide groove 111. A screw rod 112 is rotatably connected in the slide groove 111 along its length direction, and one end of the slider 113 is threadedly connected to the screw rod 112. The end of the screw rod 112 away from the central axis of the rotating disk 110 extends to the outside of the rotating disk 110. A side sampling mechanism 130 is installed on the slider 113. The output end of the central water inlet pipe 120 extends to the side of the rotating disk 110 away from the side sampling mechanism 130, and a first sealed bearing 121 is rotatably connected at the port. A helical gear ring 140 is installed on a side wall of the rotating disk 110 away from the side sampling mechanism 130 , and the central axis of the helical gear ring 140 coincides with the central axis of the rotating disk 110 .

[0049] The side sampling mechanism 130 includes a first connecting pipe 131. For example, Figure 5 As shown, one end of the first connecting pipe 131 is installed on the slider 113, and the other end of the first connecting pipe 131 extends vertically to the side away from the slider 113, and the port is connected to the second connecting pipe 132, and the output end of the first connecting pipe 131 is connected to the central water inlet pipe 120. The end of the second connecting pipe 132 away from the first connecting pipe 131 extends horizontally to the side away from the central axis of the turntable 110, and the port is connected to the sampling pipe 133. The other end of the sampling pipe 133 extends vertically to the side away from the turntable 110, and a plurality of groups of injection ports 135 are evenly distributed on the surface of the sampling pipe 133. A spiral scraper 134 is spirally wound on the outer wall of the sampling pipe 133, and the width of the spiral scraper 134 on the side away from the sampling pipe 133 is smaller than that on the other side.

[0050] First, the screw rod 112 is rotated according to the inner diameter of the sewage pipe. The rotation of the screw rod 112 allows the slider 113 to drive the slider 113 and the first connecting pipe 131 to move along the slide groove 111 until each group of spiral scrapers 134 can fit with the inner wall of the surrounding sewage pipe. Then, each group of moving units 400 is started, and the moving unit 400 drives the device as a whole to move in the sewage pipe, and at the same time, the turntable 110 drives each group of side sampling mechanisms 130 to rotate, so that the spiral scrapers 134 slide and fit with the inner wall of the sewage pipe, and thereby scrape the sludge on the inner wall of the sewage pipe as a sample, and then enter the primary detection unit 200 through the central water inlet pipe 120 for detection, so as to obtain the values ​​of each group of pollutants in the industrial wastewater discharged by the industrial cluster area, thereby realizing the detection of the pollution source that meets the requirements.

[0051] In addition to detecting the sludge adsorbed on the inner wall of the sewage pipe, flowing industrial wastewater can also be collected through the central water inlet pipe 120.

[0052] The primary detection unit 200 includes a first detection box 210. For example, Figure 6 and Figure 7 As shown, the first detection box 210 is located on the side of the turntable 110 away from the side sampling mechanism 130, and the central axis of the first detection box 210 coincides with the central axis of the turntable 110. A first water inlet 211 is provided at the center of one end of the first detection box 210 close to the turntable 110, and an intermediate water pipe 230 is connected to the output end of the first water inlet 211, and the input end of the intermediate water pipe 230 is rotatably connected to the first sealing bearing 121, and the cavity of the intermediate water pipe 230 is connected to the cavity of the central water inlet pipe 120 through the first sealing bearing 121. A vacuum pump is provided at the junction of the intermediate water pipe 230 and the first water inlet 211. A plurality of groups of independent detection chambers 240 are distributed in a circular array in the first detection box 210, and a group of first water quality meters 250 are installed in each group of the independent detection chambers 240. The input end of the first water quality meter 250 is connected to the output end of the first water inlet 211, and the output end of the first water quality meter 250 is connected to an independent drain pipe 260. The output end of the independent drain pipe 260 extends horizontally to the side away from the central axis of the first detection box 210 to the outside of the cavity of the first detection box 210.

[0053] Furthermore, a motor outer box 220 is provided on one side of the intermediate water pipe 230, and a first waterproof motor is provided in the motor outer box 220. The output end of the first waterproof motor extends to the outside of the motor outer box 220 and is transmission-connected with a bevel gear 221, which is meshedly connected with the helical gear ring 140.

[0054] The bevel gear 221 is driven to rotate by the first waterproof motor, and the bevel gear 221 is then used to drive the helical gear ring 140 to rotate, so that each set of spiral scrapers 134 can slide and fit with the inner wall of the sewage pipe.

[0055] The secondary detection unit 300 includes a second detection box 310. For example, Figure 8 and Fig. 9 As shown, the second detection box 310 is installed at the center of one end of the first detection box 210 away from the sampling unit 100. A secondary detection chamber 320 is provided in the second detection box 310, and a second water quality measuring instrument 340 is installed in the secondary detection chamber 320. The input end and the output end of the second water quality measuring instrument 340 are respectively connected with a secondary sampling tube 350 and a secondary drainage tube 360, the secondary sampling tube 350 is provided with a liquid pump 351, and the secondary drainage tube 360 ​​is provided with an electric ball valve 361. The ends of the secondary sampling tube 350 and the secondary drainage tube 360 ​​away from the second water quality measuring instrument 340 extend to the outside of the cavity of the second detection box 310.

[0056] After the wastewater sample or sludge sample enters the intermediate water pipe 230, it is respectively injected into each group of first water quality measuring instruments 250 through the first water inlet 211, and each group of first water quality measuring instruments 250 performs separate measurements at the same time. When one or more groups of first water quality measuring instruments 250 detect abnormal samples, the internal signal output module sends a signal to the external staff, and then the external staff starts the second water quality measuring instrument 340, and the wastewater in the sewage pipe is introduced into the second water quality measuring instrument 340 through the secondary sampling tube 350 through the liquid pump 351 for secondary detection. To ensure the accuracy of the detection.

[0057] A bottom cavity 330 is provided on the side of the secondary detection cavity 320 away from the primary detection unit 200, and a quadrangular base 370 is provided on the inner wall of the side of the bottom cavity 330 away from the secondary detection cavity 320. The quadrangular base 370 is a quadrangular pyramid structure. Each group of the mobile units 400 is mounted on the quadrangular base 370 and a corresponding group of side walls.

[0058] The moving unit 400 includes an electric push rod 410. For example, Fig.10 and Fig.11As shown, the electric push rod 410 is installed on the side wall of the quadrangular base 370, the output end of the electric push rod 410 extends obliquely to the outside of the bottom cavity 330, and a motor mounting box 430 is installed at the port. A second sealed bearing 420 is provided at the junction of the electric push rod 410 and the side wall of the bottom cavity 330. A second waterproof motor 440 is installed on the motor mounting box 430, and a plurality of groups of moving wheels 450 are arranged at equal intervals on both sides of the motor mounting box 430, and the output end of the second waterproof motor 440 is connected to the input end of the moving wheel 450 in a transmission manner. A plurality of groups of mud-breaking anti-slip plates 460 are distributed in an annular array on the side wall of the moving wheel 450, and the mud-breaking anti-slip plates 460 are of a V-shaped structure, and a mud-slinging plate 470 with a fan-shaped cross-section is provided at one end of the mud-breaking anti-slip plate 460 close to the central axis of the moving wheel 450.

[0059] When the device as a whole enters the sewage pipe, each set of electric push rods 410 is started, and each set of electric push rods 410 pushes each set of motor installation boxes 430 to extend obliquely to the side away from the second detection box 310 until the mud-breaking anti-slip plate 460 on each set of moving wheels 450 fits the inner wall of the sewage pipe. Then, each set of second waterproof motors 440 is started, and the second waterproof motors 440 drive each set of moving wheels 450 to rotate, so that the device as a whole can move forward in the pipe. While moving forward, each group of mud-breaking anti-slip plates 460 rolls and fits against the inner wall of the sewage pipe. Since the mud-breaking anti-slip plates 460 are V-shaped structures, when they come into contact with the inner wall of the sewage pipe, they can break the sludge on the inner wall to both sides, and then throw out the broken sludge through the mud-throwing plates 470 with fan-shaped structures at the bottom. In addition, the mud-breaking anti-slip plates 460 increase the pressure between the moving wheels 450 and the inner wall of the sewage pipe, avoiding the moving wheels 450 from slipping when the device moves forward, and improving the smoothness and stability of the device when moving forward. When the device needs to perform fixed-point sampling, it only needs to control the electric push rod 410 to push the moving wheels 450 to continue squeezing the inner wall of the sewage pipe, thereby fixing the device as a whole.

[0060] 1. The mobile unit 400 drives the entire device to move in the sewage pipe, thereby meeting the requirements of point sampling without disassembling the pipe. And while moving, the turntable 110 is used to drive each group of side sampling mechanisms 130 to rotate. In addition, the position of each group of side sampling mechanisms 130 can be adjusted according to the inner diameter of the sewage pipe, so that it can always slide and fit with the inner wall of the sewage pipe. Not only can the central water inlet pipe 120 be used to extract industrial wastewater samples, but also the sludge on the inner wall of the sewage pipe can be collected as a sample by rotating the side sampling mechanism 130, thereby enriching the functionality of the device and ensuring the diversity of sample collection by using its movable characteristics.

[0061] 2. As the device moves forward, each group of mud-breaking anti-slip plates 460 rolls and fits against the inner wall of the sewage pipe. Since the mud-breaking anti-slip plates 460 are V-shaped structures, when they come into contact with the inner wall of the sewage pipe, they can break the sludge on the inner wall to both sides, thus avoiding the slipping of the moving wheels 450 when the device moves forward, and improving the smoothness and stability of the device when moving forward. And when the device needs to perform fixed-point sampling, it only needs to control the electric push rod 410 to push the moving wheels 450 to continue squeezing the inner wall of the sewage pipe, so as to fix the entire device. This improves the compatibility of the device.

[0062] 3. When the side sampling mechanism 130 collects sludge samples, the sludge is scraped off by the spiral scraper 134. Since the spiral scraper 134 has a spiral structure and is wound around the sampling tube 133, the sludge will not accumulate on a certain point on the surface of the sampling tube 133 after being scraped off by the spiral scraper 134, but will be arranged in sequence along its spiral path, and finally enter the cavity of the sampling tube 133 through the injection port 135, thereby preventing the sludge from clogging the injection port 135, thereby improving the fluency of the sampling work and the convenience of the subsequent cleaning work of the device.

[0063] 4. After the wastewater sample or sludge sample enters the intermediate water pipe 230, it is respectively injected into each group of first water quality measuring instruments 250 through the first water inlet 211, and each group of first water quality measuring instruments 250 performs separate measurements simultaneously. When one or more groups of first water quality measuring instruments 250 detect an abnormality in the sample, the second water quality measuring instrument 340 is started, and the wastewater in the sewage pipe is introduced into the second water quality measuring instrument 340 through the secondary sampling tube 350 by the liquid pump 351 for secondary detection, so as to ensure the accuracy of the detection.

[0064] Based on the above-mentioned industrial cluster complex pollution source testing device, the embodiment of the present invention further proposes a testing method for the testing device. Exemplarily, the testing method includes:

[0065] The screw rod is rotated according to the inner diameter of the sewage pipe, and the slider can drive the slider and the first pipe to move along the slide groove through the rotation of the screw rod until each set of spiral scrapers can fit with the inner wall of the surrounding sewage pipe;

[0066] Start each group of electric push rods, and each group of electric push rods pushes each group of motor installation boxes to extend obliquely to the side away from the second detection box until the mud-breaking anti-slip plate on each group of moving wheels fits with the inner wall of the sewage pipe;

[0067] Start each set of second waterproof motors, and the second waterproof motors drive each set of moving wheels to rotate, so that the entire device can move forward in the pipeline;

[0068] At the same time, the vacuum pump and the first waterproof motor are started, the bevel gear is driven to rotate by the first waterproof motor, and then the bevel gear drives the turntable and each set of side sampling mechanisms to rotate, so that the spiral scraper slides and fits with the inner wall of the sewage pipe;

[0069] The spiral scraper scrapes off the sludge on the inner wall of the sewage pipe and transports it to the primary detection unit. The central water inlet pipe samples the flowing industrial wastewater and transports it to the primary detection unit at the same time.

[0070] The wastewater samples and sludge samples were tested simultaneously and independently by the first water quality measuring instrument of each group;

[0071] When one or more of the first water quality measuring instruments detects abnormal samples, the second water quality measuring instrument is started, and the wastewater in the sewage pipe is introduced into the second water quality measuring instrument through the secondary sampling tube for secondary testing by the liquid pump;

[0072] If the second test is also abnormal, it means that the pollution exceeds the standard.

[0073] When the device moves in the sewage pipe, the turntable drives each set of side sampling mechanisms to rotate. The position of each set of side sampling mechanisms can also be adjusted according to the inner diameter of the sewage pipe, so that it can always slide and fit with the inner wall of the sewage pipe. Not only can the central water intake pipe be used to extract industrial wastewater samples, but the sludge on the inner wall of the sewage pipe can also be collected as samples by rotating the side sampling mechanisms.

[0074] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
