[0014] Furthermore.

[0015] The beneficial effects of the present invention are as follows: 1. By setting the sampling mechanism in the present invention, the interior of the box body is divided by the buckling assembly. The upper layer is the middle-layer sewage, and the lower layer is the bottom-layer sewage. Sampling is carried out once into the sewer, and sewage at different positions can be sampled separately, increasing the diversity of samples and facilitating adaptation to the complex sewage environment.

[0017] 3. By setting the buckling assembly in the present invention, the concave-shaped sleeve moves to the bottom of the box body, forming a relatively closed space between the concave-shaped sleeve and the bottom of the box body. The sewage is stored inside the box body. After lifting it to the ground, the plug is removed from the bottom, and the sewage is poured into the container, increasing the diversity of water body samples, facilitating the entry of solid particles while avoiding excessive particulate matter.

[0018] 4. By setting the opening and closing assembly in the present invention, during the process of lifting the box body upward, since the buoyancy force received by the float balls gradually decreases, the cover plate gradually closes, and sewage no longer enters. A relatively closed space is formed between the cover plate and the buckle plate, storing the surface-layer sewage in the collection box, sampling the sewage at the upper, middle, and lower positions simultaneously, reducing the sampling time, quickly closing the container, reducing the sample exposure time, and avoiding the loss of key components.

Detailed Description of the Preferred Embodiments

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.

[0022] Embodiment 1, please refer to Figures 1 - 5 , the present invention provides a technical solution: a sewage detection sewer sewage collection device is described as follows.

[0023] Including: A body 1, with a telescopic rod 4 provided at the bottom of the body 1; The sampling mechanism 5 is arranged at the bottom of the telescopic rod 4, and the sampling mechanism 5 is used to sample the sewage at a position below the sewage liquid level in the sewer; The upper layer water intake mechanism 6 is symmetrically arranged on the top of the sampling mechanism 5, and the upper layer water intake mechanism 6 is used to sample the sewage on the surface layer of the liquid level; The sewer sewage sampling device for sewage detection further includes: The mounting plate 2 is arranged at the bottom of the machine body 1, and the inner wall of the mounting plate 2 is sleeved with the outer wall of the telescopic rod 4; 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.

[0024] During operation, the worker unfolds the support rods 3 and props them on the ground, making the machine body 1 face the sewer wellhead. The telescopic rod 4 drives the sampling mechanism 5 to go deep downward. The upper layer water intake mechanism 6 makes the inlet float at the sewage liquid level position along the telescopic rod 4 through the buoyancy effect to sample the sewage on the surface layer of the sewer. After the sampling is completed, it is lifted upward by a certain distance, and then the sampling mechanism 5 samples the sewage at two positions below the liquid level. Finally, the machine body 1 drives the telescopic rod 4 to retract. The user pumps the water inside the sampling mechanism 5 and the upper layer water intake mechanism 6 into a container for storage respectively, and then sends it for inspection.

[0025] The sampling mechanism 5 includes: The box body 501, and the bottom of the inner wall of the box body 501 is rotatably connected to the bottom of the telescopic rod 4; The fastening assembly 503 is installed on the top of the inner wall of the box body 501, and the fastening assembly 503 is used to cooperate with the box body 501 to mix and sample the water below the liquid level; The filtering assembly 504 is symmetrically arranged on the top of the box body 501, and the filtering assembly 504 is used to sample the sewage at the liquid level height above the box body 501.

[0026] The sampling mechanism 5 further includes: The plugging head 502 is arranged at the bottom of the box body 501. The plugging head 502 has a larger diameter. After the sampling is completed, the plugging head 502 is removed to inject the sewage and sundries into a container for storage, and then sent for inspection; The strip-shaped holes 505 are evenly opened at the lower part of the side surface of the box body 501. The position of the fastening assembly 503 is higher than the position of the strip-shaped holes 505. During the sewage detection process, in addition to the liquid components to be detected, the solid particle components also need to be extracted and detected. The strip-shaped holes 505 are set to be longer to allow some smaller-sized solid particles to enter.

[0027] After the telescopic rod 4 lowers the box body 501 into the sewage, the built-in drive of the fastening component 503 is activated, causing the fastening component 503 to be above the inner wall of the box body 501. Sewage enters the interior of the box body 501 through the strip-shaped holes 505. After the interior of the box body 501 is filled with sewage, the fastening component 503 moves downward, retaining the sewage inside the box body 501 in the space formed between the fastening component 503 and the bottom of the box body 501. At the same time, the sewage above the box body 501 is filtered by the filtering component 504 and pumped above the box body 501. With the fastening component 503 as the dividing line inside the box body 501, the upper part is the middle-layer sewage, and the lower part is the bottom-layer sewage. Sampling directly into the sewer at one time enables separate sampling of sewage at different positions, increasing the diversity of samples and facilitating adaptation to the complex sewage environment. Since solid debris is also within the detection scope during sewage detection, the sewage sample in the box body 501 can retain a certain amount of solid particles under the action of the fastening component 503, which is beneficial to improving the detection accuracy.

[0028] The upper-layer water intake mechanism 6 includes: A sliding sleeve 601, the inner wall of the sliding sleeve 601 is slidably connected to the outer wall of the telescopic rod 4; An airbag ring 602, the airbag ring 602 is installed on the outer wall of the sliding sleeve 601; An opening and closing component 603, the inner wall of the opening and closing component 603 is 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, and two opening and closing components 603 are symmetrically arranged.

[0029] The upper-layer water intake mechanism 6 further includes: A hose 604, the top of the hose 604 is connected to the bottom of the opening and closing component 603, and the shape of the hose 604 conforms to the shape of the opening and closing component 603; A collection box 605, the bottom of the collection box 605 is connected to the top of the box body 501, and the top of the collection box 605 is connected to the bottom of the hose 604.

[0030] 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 be at a position flush with the liquid level. The opening and closing component 603 is opened under the action of buoyancy, allowing sewage to enter the interior of the opening and closing component 603 and then into the collection box 605 through the hose 604. During the upward lifting process after the collection is completed, the opening and closing component 603 closes, reducing the sloshing and spilling of sewage during movement, which may result in an insufficient amount of sample collection and the need for rework, affecting the collection progress. The surface layer of sewage may be enriched with oil, suspended solids, microorganisms, or volatile pollutants, and these components are easily disturbed or volatilized. The one-way opening and closing plate design can quickly seal the container, reduce the exposure time of the sample, and prevent the loss of key components.

[0031] Example 2, please refer to Figures 1 - 8 , the present invention provides a technical solution: on the basis of Example 1, the fastening assembly 503 includes: The telescopic columns 5031 are uniformly arranged at the top of the inner wall of the box body 501; The concave-shaped sleeve 5032 has an inner wall sleeved with the outer wall of the telescopic rod 4, and the top of the concave-shaped sleeve 5032 is connected to the bottom of the telescopic column 5031. The concave-shaped sleeve 5032 is used to block the strip-shaped hole 505 when moving downward, so that the sewage inside the box body 501 remains inside the box body 501 to achieve collection.

[0032] The fastening assembly 503 further includes: The rotating rods 5033 are uniformly arranged at the bottom of the concave-shaped sleeve 5032, and the outer walls of the rotating rods 5033 are rotatably connected to the inner wall of the concave-shaped sleeve 5032; The elastic rods 5034 are uniformly arranged on the outer walls of the rotating rods 5033, and the elastic rods 5034 are made of elastic rubber material.

[0033] After the box body 501 is immersed in sewage, the sewage enters the inside of the box body 501 through the strip-shaped hole 505, and large debris enters the box body 501 through the strip-shaped hole 505. After a period of time, the built-in drive in the concave-shaped sleeve 5032 drives the rotating rod 5033 to rotate to the vertical position, blocking the middle position of the strip-shaped hole 505, reducing the inlet area of the strip-shaped hole 505, so that smaller debris enters the box body 501 with the water flow, avoiding too much debris, and making the elastic rods 5034 on the rotating rod 5033 extend out of the box body 501. The elastic rods 5034 flow with the water flow, causing the sewage around the box body 501 to be stirred to a certain extent, and pumping the mixed sewage to the bottom position inside the box body 501 for storage; After a period of time, the telescopic column 5031 drives the concave-shaped sleeve 5032 to move downward. At this time, the rotating rod 5033 rotates back to the horizontal position. Finally, the concave-shaped sleeve 5032 moves to the bottom of the box body 501, so that the concave-shaped sleeve 5032 and the bottom of the box body 501 form a relatively closed space, storing the sewage inside the box body 501. After lifting it to the ground, the plug 502 is taken out from the bottom, and the sewage is poured into the container, increasing the diversity of the water body sample, facilitating the entry of solid particles and avoiding too many particulate matters.

[0034] The filtering assembly 504 includes: The blocking rods 5041 are symmetrically arranged on the inner wall of the box body 501, the outer walls of the blocking rods 5041 are sleeved with the inner wall of the box body 501, and the bottom of the blocking rods 5041 is connected to the top of the concave-shaped sleeve 5032; The filtering sleeves 5042 are symmetrically arranged on the top of the box body 501; The rotating plate 5043, the bottom of the rotating plate 5043 is rotatably connected to the top of the filter sleeve 5042; The scraping rod 5044, the top of the scraping rod 5044 is connected to the bottom of the rotating plate 5043, and the outer wall of the scraping rod 5044 is in contact with the outer wall of the filter sleeve 5042.

[0035] During the process of the telescopic column 5031 driving the concave-shaped sleeve 5032 to move downward, since the outer wall of the concave-shaped sleeve 5032 fits with the inner wall of the box body 501, the concave-shaped sleeve 5032 moves downward. Due to the change in pressure, a groove body is formed between the upper space of the box body 501 and the concave-shaped sleeve 5032, and the sewage above the box body 501 is stored above the inside of the box body 501. The sewage passes through the filter sleeve 5042 and enters above the box body 501, reducing the situation of blockage caused by solid particles. At the same time, driven by the water flow, the rotating plate 5043 rotates, thereby driving the scraping rod 5044 to clean the surface of the filter sleeve 5042, keeping the filter sleeve 5042 clean, and enabling the sewage to quickly enter the box body 501.

[0036] The opening and closing assembly 603 includes: The extension plate 6032, the inner wall of the extension plate 6032 is connected to the outer wall of the sliding sleeve 601, and the outer wall of the extension plate 6032 is provided with a buckle plate 6031; The bent rod 6037, the bent rod 6037 is uniformly arranged on the inner wall of the buckle plate 6031 away from the extension plate 6032. The bent rod 6037 blocks the sundries floating on the waterless surface to prevent large sundries from entering the collection box 605 and causing blockage; The cover plate 6033, the outer wall of the cover plate 6033 is rotatably connected to the top of the buckle plate 6031.

[0037] The opening and closing assembly 603 further includes: The connecting rod 6034, the connecting rod 6034 is symmetrically arranged on the outer wall of the buckle plate 6031; The arc-shaped rod 6035, the arc-shaped rod 6035 is arranged 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; The floating ball 6036, the floating ball 6036 is uniformly arranged on the surface of the arc-shaped rod 6035. The arc-shaped rod 6035 connects the floating balls 6036 in series and drives the connecting rod 6034 to rotate to lift the cover plate 6033 upward.

[0038] Since the airbag ring 602 is at the same level as the liquid surface, the height of the extension plate 6032 is lower than that of the airbag ring 602. At this time, the extension plate 6032 and the buckle plate 6031 are below the liquid surface. The floating ball 6036 floats upward under the influence of buoyancy at this time, driving one end of the cover plate 6033 away from the buckle plate 6031, exposing the opening of the buckle plate 6031, allowing sewage to enter the collection box 605 through the buckle plate 6031. During the process of lifting the box body 501 upward, since the buoyancy received by the floating ball 6036 gradually decreases, the cover plate 6033 gradually closes, and sewage no longer enters. A relatively enclosed space is formed between the cover plate 6033 and the buckle plate 6031, storing the sewage on the surface layer in the collection box 605, sampling the sewage at three positions of upper, middle and lower simultaneously, reducing the time spent on sampling, quickly closing the container, reducing the sample exposure time, and avoiding the loss of key components.

[0039] The specific working process is as follows: During operation, the worker unfolds the support rod 3 and props it on the ground, aiming the machine body 1 at the sewer manhole. The telescopic rod 4 drives the collection mechanism 5 to go deep downward. The upper water intake mechanism 6 makes the inlet float at the sewage liquid surface position along the telescopic rod 4 through the buoyancy effect. 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 assembly 603 to be at the same level as the liquid surface. The opening and closing assembly 603 is opened under the buoyancy effect, allowing sewage to enter the inside of the opening and closing assembly 603 and enter the collection box 605 through the hose 604. After the collection is completed, during the upward lifting process, the opening and closing assembly 603 closes, reducing the sloshing and spilling of sewage during movement. After the water intake is completed, lift it upward by a certain distance, and then make the collection mechanism 5 collect 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 fastening assembly 503 is activated, making the fastening assembly 503 above the inner wall of the box body 501, allowing sewage to enter the inside of the box body 501 through the strip-shaped holes 505. After filling the inside of the box body 501 with sewage, the fastening assembly 503 moves downward, leaving the sewage inside the box body 501 in the space formed between the fastening 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 filtering assembly 504 and pumped above the box body 501; Make the inside of the box body 501 be divided by the fastening assembly 503. The upper part is the middle-layer sewage, and the lower part is the bottom-layer sewage, enabling separate sampling of the sewage at different positions around the water tank during a one-time entry into the sewer for sampling; finally, the machine 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 for storage respectively, and then sends them for inspection.
