[0045] The beneficial effects of the present invention are as follows:

[0046] 1. The present invention sets a collection mechanism so that the interior of the box is divided by a snap-fit assembly, with the middle layer of sewage above and the bottom layer of sewage below, so that sampling can be carried out inside the sewer at one time. Sewage at different locations can be sampled separately, increasing the diversity of samples and facilitating adaptation to the complex environment of sewage.

[0047] 2. This invention incorporates an upper water intake mechanism to reduce the risk of wastewater sloshing during transport, which can lead to spillage and insufficient sample collection, necessitating rework and impacting collection progress. The surface layer of wastewater can also accumulate grease, suspended matter, microorganisms, or volatile pollutants, all of which are easily disturbed or volatilized. The one-way opening and closing plate design allows for rapid closure of the container, reducing sample exposure time and preventing the loss of key components.

[0048] 3. The present invention provides a snap-fit assembly, and the concave sleeve moves to the bottom of the box, so that the concave sleeve and the bottom of the box form a relatively closed space, storing sewage inside the box. After it is lifted to the ground, the plug is removed from the bottom and the sewage is poured into the container, thereby increasing the diversity of water samples, facilitating the entry of solid particles and avoiding excessive particulate matter.

[0049] 4. The present invention provides an opening and closing assembly. When the box body is pulled upward, the buoyancy of the float gradually decreases, causing the cover to gradually close and sewage to no longer enter. A relatively closed space is formed between the cover and the gusset plate, and the surface sewage is stored in the collection box. Sewage is sampled simultaneously at the upper, middle and lower positions of the sewage, reducing the time spent on sampling. The container can be quickly closed, reducing the exposure time of the sample and avoiding the loss of key components. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0060] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a sewage collection device for sewage detection is described as follows.

[0061] include:

[0062] The body 1 has a telescopic rod 4 at the bottom thereof;

[0063] The collecting mechanism 5 is provided at the bottom of the telescopic rod 4 and is used to collect sewage below the sewage level in the sewer;

[0064] The upper water intake mechanism 6 is symmetrically arranged on the top of the collection mechanism 5, and is used to collect sewage on the surface of the liquid;

[0065] The sewage collection equipment for sewage detection also includes:

[0066] The mounting plate 2 is arranged at the bottom of the body 1, and the inner wall of the mounting plate 2 is sleeved with the outer wall of the telescopic rod 4;

[0067] The support rods 3 are evenly arranged on the inner wall of the mounting plate 2 , and the outer wall of the support rods 3 is rotatably connected to the inner wall of the mounting plate 2 .

[0068] During work, the worker unfolds the support rod 3 and supports it on the ground, so that the body 1 faces the sewer manhole, and the telescopic rod 4 drives the collection mechanism 5 to go deeper downward. The upper water intake mechanism 6 uses buoyancy to make the inlet float along the telescopic rod 4 at the sewage liquid surface position, and takes water from the surface of the sewer sewage. After the water is taken, it is pulled upward for a distance, and then the collection mechanism 5 collects sewage at two positions below the liquid surface. Finally, the body 1 drives the telescopic rod 4 to retract, and the user pumps the water inside the collection mechanism 5 and the upper water intake mechanism 6 into containers respectively, and then sends them for inspection.

[0069] The collection mechanism 5 includes:

[0070] Box body 501, the bottom of the inner wall of box body 501 is rotatably connected to the bottom of telescopic rod 4;

[0071] The snap-fit assembly 503 is mounted on the top of the inner wall of the box 501 and is used to cooperate with the box 501 to mix and collect water below the liquid level;

[0072] The filter assembly 504 is symmetrically arranged on the top of the box 501 , and is used to collect sewage at a liquid level above the box 501 .

[0073] The collection mechanism 5 also includes:

[0074] The plugging head 502 is set at the bottom of the box 501. The plugging head 502 is set to a larger diameter. After the collection is completed, the plugging head 502 is removed to allow the sewage and debris to be injected into the container for storage and then sent for inspection;

[0075] The strip holes 505 are evenly arranged at the lower side of the box body 501. The position of the snap-fit assembly 503 is higher than the position of the strip holes 505. In the process of sewage detection, in addition to the liquid components that need to be detected, the solid particle components also need to be extracted and detected. The strip holes 505 are set longer to allow some smaller solid particles to enter.

[0076] After the telescopic rod 4 lowers the box 501 into the sewage, the built-in drive of the buckle assembly 503 is turned on, so that the buckle assembly 503 is above the inner wall of the box 501, allowing the sewage to enter the box 501 through the strip hole 505. After the box 501 is filled with sewage, the buckle assembly 503 moves downward, leaving the sewage inside the box 501 in the space formed by the buckle assembly 503 and the bottom of the box 501. At the same time, the sewage above the box 501 is filtered by the filter assembly 504 and pumped to the top of the box 501;

[0077] The interior of the box 501 is divided by the snap-fit component 503, with the middle layer of sewage at the top and the bottom layer of sewage at the bottom, so that sampling can be carried out inside the sewer at one time. Sewage at different locations can be sampled separately, increasing the diversity of samples and facilitating adaptation to the complex environment of sewage. Since solid debris is also within the detection range when sewage is detected, the sewage sample in the box 501 can maintain a certain amount of solid particles under the action of the snap-fit component 503, which is conducive to improving detection accuracy.

[0078] The upper water intake mechanism 6 comprises:

[0079] A sliding sleeve 601, the inner wall of the sliding sleeve 601 is slidably connected to the outer wall of the telescopic rod 4;

[0080] An airbag ring 602 is mounted on the outer wall of the sliding sleeve 601;

[0081] The opening and closing component 603 has an inner wall connected to the outer wall of the sliding sleeve 601 . The height of the opening and closing component 603 is lower than the height of the airbag ring 602 . Two opening and closing components 603 are symmetrically arranged.

[0082] The upper water intake mechanism 6 also includes:

[0083] Hose 604, the top of hose 604 is connected to the bottom of opening and closing component 603, and the shape of hose 604 is consistent with the shape of opening and closing component 603;

[0084] The collecting box 605 has a bottom connected to the top of the box body 501 , and a top connected to the bottom of the hose 604 .

[0085] After entering the sewage, the buoyancy generated by the inflation of the airbag ring 602 causes the airbag ring 602 to drive the sleeve 601 and the opening and closing component 603 to a position level with the liquid surface. The opening and closing component 603 is opened by the buoyancy, allowing the sewage to enter the opening and closing component 603 and then enter the collection box 605 through the hose 604. After the collection is completed, the opening and closing component 603 is closed during the upward pulling process, reducing the shaking and spillage of the sewage during the movement, resulting in insufficient sample collection, requiring rework, and affecting the collection progress. The surface of the sewage may be enriched with grease, suspended matter, microorganisms, or volatile pollutants, which are easily disturbed or volatilized. The one-way opening and closing plate design can quickly close the container, reducing the exposure time of the sample and preventing the loss of key components.

[0086] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Example 1, the fastening component 503 includes:

[0087] Telescopic columns 5031 are evenly arranged on the top of the inner wall of the box 501;

[0088] The concave sleeve 5032 has an inner wall that is socketed with the outer wall of the telescopic rod 4, and a top of the concave sleeve 5032 is connected to the bottom of the telescopic column 5031. The concave sleeve 5032 is used to block the strip hole 505 when moving downward, so that the sewage inside the box 501 remains inside the box 501 to achieve collection.

[0089] The fastening assembly 503 further includes:

[0090] The rotating rod 5033 is evenly arranged at the bottom of the concave sleeve 5032, and the outer wall of the rotating rod 5033 is rotatably connected to the inner wall of the concave sleeve 5032;

[0091] The elastic rods 5034 are evenly arranged on the outer wall of the rotating rod 5033 and are made of elastic rubber material.

[0092] After the box 501 is immersed in sewage, the sewage enters the box 501 through the strip hole 505. Large pieces of debris enter the box 501 through the strip hole 505. After a period of time, the built-in drive of the concave sleeve 5032 drives the rotating rod 5033 to rotate vertically, blocking the middle position of the strip hole 505, reducing the entrance area of the strip hole 505, allowing smaller debris to enter the box 501 with the water flow, and preventing excessive debris. The elastic rod 5034 on the rotating rod 5033 extends out of the box 501. The elastic rod 5034 flows with the water flow, causing the sewage around the box 501 to be stirred to a certain extent, and the mixed sewage is pumped to the bottom position of the box 501 for storage;

[0093] After a period of time, the telescopic column 5031 drives the concave sleeve 5032 to move downward. At this time, the rotating rod 5033 rotates back to the horizontal position, and finally the concave sleeve 5032 moves to the bottom of the box 501, so that the concave sleeve 5032 and the bottom of the box 501 form a relatively closed space, storing the sewage inside the box 501. After it is lifted to the ground, the plug 502 is removed from the bottom and the sewage is poured into the container, thereby increasing the diversity of water samples, facilitating the entry of solid particles and avoiding excessive particulate matter.

[0094] The filter assembly 504 includes:

[0095] The blocking rod 5041 is symmetrically arranged on the inner wall of the box body 501, the outer wall of the blocking rod 5041 is sleeved with the inner wall of the box body 501, and the bottom of the blocking rod 5041 is connected to the top of the concave sleeve 5032;

[0096] The filter sleeve 5042 is symmetrically arranged on the top of the box 501;

[0097] A rotating plate 5043, the bottom of which is rotatably connected to the top of the filter sleeve 5042;

[0098] The scraper rod 5044 has a top connected to the bottom of the rotating plate 5043 , and an outer wall of the scraper rod 5044 contacts an outer wall of the filter sleeve 5042 .

[0099] As the telescopic column 5031 drives the concave sleeve 5032 to move downward, the outer wall of the concave sleeve 5032 fits with the inner wall of the box body 501, causing the concave sleeve 5032 to move downward. Due to the change in pressure, the upper space of the box body 501 and the concave sleeve 5032 form a groove, which stores the sewage above the box body 501 in the upper part of the box body 501. The sewage enters the upper part of the box body 501 through the filter sleeve 5042, reducing the blockage caused by solid particles. At the same time, driven by the water flow, the rotating plate 5043 rotates, thereby driving the scraper rod 5044 to clean the surface of the filter sleeve 5042, keeping the filter sleeve 5042 clean, and allowing the sewage to quickly enter the box body 501.

[0100] The opening and closing assembly 603 includes:

[0101] An extension plate 6032 , the inner wall of which is connected to the outer wall of the sliding sleeve 601 , and a buckle plate 6031 is provided on the outer wall of the extension plate 6032 ;

[0102] Bent rods 6037 are evenly arranged on the inner wall of the gusset plate 6031 away from the extension plate 6032. The bent rods 6037 block debris floating on the dry surface to prevent large debris from entering the collection box 605 and causing blockage;

[0103] The cover plate 6033 , the outer wall of the cover plate 6033 is rotatably connected to the top of the buckle plate 6031 .

[0104] The opening and closing assembly 603 further includes:

[0105] Connecting rod 6034, which is symmetrically arranged on the outer wall of the gusset plate 6031;

[0106] The arc-shaped rod 6035 is provided on the surface of the connecting rod 6034, and the outer wall of the arc-shaped rod 6035 is connected to the bottom of the cover plate 6033;

[0107] The floating balls 6036 are evenly arranged on the surface of the arc rod 6035. The arc rod 6035 connects the floating balls 6036 in series and drives the connecting rod 6034 to rotate to lift the cover plate 6033 upward.

[0108] Since the airbag ring 602 is in a position level with the liquid surface, the height of the extension plate 6032 is lower than the airbag ring 602. At this time, the extension plate 6032 and the buckle plate 6031 are below the liquid surface. At this time, the float 6036 floats upward due to the buoyancy, thereby driving one end of the cover 6033 away from the buckle plate 6031, exposing the opening of the buckle plate 6031, and allowing the sewage to enter the collection box 605 through the buckle plate 6031. In the process of pulling the box body 501 upward, the buoyancy of the float 6036 gradually decreases, causing the cover 6033 to gradually close, and sewage no longer enters. A relatively closed space is formed between the cover 6033 and the buckle plate 6031, and the surface sewage is stored in the collection box 605. The sewage is sampled at the upper, middle and lower positions at the same time, which reduces the time spent on sampling. The container can be quickly closed, reducing the exposure time of the sample and avoiding the loss of key components.

[0109] The specific workflow is as follows:

[0110] During operation, the worker unfolds the support rod 3 and supports it on the ground, so that the machine body 1 faces the sewer manhole, and the telescopic rod 4 drives the collection mechanism 5 to go deeper downward. The upper water intake mechanism 6 uses the buoyancy to make the entrance float along the telescopic rod 4 at the sewage liquid surface position. After entering the sewage, due to the buoyancy generated by the inflation of the airbag ring 602, the airbag ring 602 drives the sliding sleeve 601 and the opening and closing component 603 to a position flush with the liquid surface. The opening and closing component 603 is opened by the buoyancy, allowing the sewage to enter the interior of the opening and closing component 603 and enter the collection box 605 through the hose 604. After the collection is completed, the opening and closing component 603 is closed during the upward pulling process to reduce the generation of sewage during the movement. The water is shaken to spill, and after the water is taken out, it is pulled upward for a distance, and then the collecting mechanism 5 collects the sewage at two positions below the liquid surface. After the telescopic rod 4 lowers the box body 501 into the sewage, the built-in drive of the buckle assembly 503 is turned on, so that the buckle assembly 503 is above the inner wall of the box body 501, so that the sewage enters the box body 501 from the strip hole 505. After the box body 501 is filled with sewage, the buckle assembly 503 moves downward, and the sewage inside the box body 501 is retained in the space formed by the buckle assembly 503 and the bottom of the box body 501. At the same time, the sewage above the box body 501 is filtered by the filter assembly 504 and pumped to the top of the box body 501.

[0111] The interior of the box 501 is divided by the snap-fit assembly 503, with the middle layer of sewage at the top and the bottom layer of sewage at the bottom, so that the sewage at different positions around the water tank can be sampled separately by entering the sewer for sampling at one time; finally, the body 1 drives the telescopic rod 4 to retract, and the user pumps the water inside the collection mechanism 5 and the upper water intake mechanism 6 into the container respectively, and then sends it for inspection.
