Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0021] The utility model discloses a device for quantitatively collecting and enriching sludge in a sewage pipe, which is mainly used for the mixed collection of sewage and sludge. The sludge has high fluidity and is easy to leak from the bottom, affecting the accuracy of quantitative collection. At the same time, it will cause uneven distribution of target substances during the enrichment process, thereby affecting the detection results.

[0022] Reference Figure 1 、 Figure 4 and Figure 5A device for quantitatively collecting sludge in a sewage pipe comprises a horizontal bar 1, a first vertical bar 2 and a second vertical bar 3. A sampling chamber is opened inside the second vertical bar 3. A support block is fixed on the inner wall of the sampling chamber. A motor 17 is installed on the top outer wall of the support block. The output end of the motor 17 is connected to a first telescopic rod 15. A spiral blade 9 is installed on the circumferential outer wall of the first telescopic rod 15 away from the motor 17. A baffle 7 is connected to the circumferential inner wall of the sampling chamber near the bottom through a rotating shaft. Micropores are provided on the outer wall of the baffle 7, and an electromagnet 8 is installed at one end of the baffle 7.

[0023] During the specific implementation process, when the user takes samples, he inserts the second vertical rod 3 into the sampling point, and the motor 17 drives the spiral blade 9 installed on the first telescopic rod 15 to rotate, extracting the sludge from the pipeline and sending it into the sampling chamber. A baffle 7 connected by a rotating shaft is provided on the inner wall of the circle near the bottom of the sampling chamber. The outer wall of the baffle 7 is provided with micropores for controlling the flow and filtration of the sludge. An electromagnet 8 is installed at one end of the baffle 7 to realize the opening and closing control of the baffle 7. The micropores are used to filter out the sewage, so as to realize the quantitative collection of sludge, improve the purity of the collected sludge sample, and ensure the accuracy of the collected sludge sample volume.

[0024] Reference Figure 3 and Figure 5 In a preferred embodiment, a receiving groove and a mounting groove are opened at the bottom of the support block, a second telescopic rod 16 is installed on the bottom inner wall of the receiving groove, and one end of the second telescopic rod 16 is connected to a push plate 18.

[0025] When it is necessary to take out the sludge sample, the first telescopic rod 15 and the second telescopic rod 16 can work together to push out the sludge in the sampling chamber for the user to collect and analyze. It is also easy to clean and maintain, avoiding the impact of sludge residue on the next collection and ensuring the accuracy and reliability of the collected samples.

[0026] Reference Figure 5 In a preferred embodiment, a mounting groove is opened on the top outer wall of the push plate 18, and a round ball 19 is installed on the inner wall of the mounting groove through a rotating shaft. The width of the mounting groove is the same as the width of the mounting groove.

[0027] The ball 19 rolls in the assembly groove, replacing the traditional direct sliding contact, so that the movement of the push plate 18 is smoother, the friction between the push plate 18 and the bottom of the fixed block is reduced, and the service life is extended.

[0028] Reference Figure 1 、 Figure 2 and Figure 3In a preferred embodiment, scale lines 6 are provided on the circumferential outer walls of the first vertical rod 2 and the second vertical rod 3, and the first vertical rod 2 and the second vertical rod 3 are telescopic structures, drainage holes 5 are opened on the circumferential outer wall of the second vertical rod 3, and rubber sleeves 4 are installed on the circumferential outer walls of the cross bar 1 near both ends.

[0029] By adding a scale line 6 to control the telescopic length of the first vertical rod 2 and the second vertical rod 3, sludge at different depths in the sewage pipe can be accurately collected. After collection, the sewage is filtered through the circular hole and then discharged from the sampling chamber through the drainage hole 5, ensuring the accuracy of the sludge sampling sample. A rubber sleeve 4 is installed on the horizontal rod 1 to enhance the grip and make it more convenient for staff to operate.

[0031] The sewage is filtered through the filter plate 10 to ensure that the collected sludge sample is purer, which can improve the accuracy and reliability of the analysis results. Several adsorption balls 14 are installed inside the adsorption sleeve 11. When the motor 17 drives the filter plate 10 at the bottom of the push plate 18 to rotate, the adsorption sleeve 11 sleeved on the outer wall of the filter plate 10 also rotates, further enhancing the adsorption capacity of harmful substances in the sludge sample and improving the uniformity of the target substance in the enrichment process, thereby ensuring the enrichment effect.

[0032] Reference Figure 4 and Figure 5 In a preferred embodiment, circular holes are opened on the outer wall of the filter plate 10, the top outer wall and one side outer wall of the adsorption sleeve 11, and a threaded groove is opened on the circumferential inner wall of the filter plate 10, and a fixing plug 13 is installed on the inner wall of the threaded groove.

[0033] The adsorption sleeve 11 and the filter plate 10 are fixed by the fixing plug 13, thereby ensuring a tight and reliable connection between them during the enrichment process. At the same time, when disassembly for sampling is required, the adsorption sleeve 11 and the filter plate 10 can be easily separated by simply rotating the fixing plug 13, which is convenient and quick.

Activated carbon has a huge specific surface area and pore structure, and can effectively adsorb pollutants such as organic matter, colloids, and heavy metals in water, which is crucial for subsequent testing and analysis.

[0035] Working principle: When in use, the user takes samples by controlling the telescopic length of the first vertical rod 2 and the second vertical rod 3 through the added scale line 6 to collect sludge at different depths in the sewage pipe, insert the second vertical rod 3 into the sampling point, and the motor 17 drives the spiral blade 9 installed on the first telescopic rod 15 to rotate, extracting the sludge from the pipe and sending it into the sampling chamber. A baffle 7 connected by a rotating shaft is provided on the inner wall of the circle near the bottom of the sampling chamber, and an electromagnet 8 is installed at one end of the baffle 7 to realize the opening and closing control of the baffle 7. After collection, the sewage is filtered through the circular hole and then discharged from the sampling chamber through the drainage hole 5 and the micropores on the baffle 7 to ensure the accuracy of the sample. While the sludge is being filtered, several adsorption balls 14 installed inside the adsorption sleeve 11 are adsorbed. When the motor 17 drives the filter plate 10 at the bottom of the push plate 18 to rotate, the adsorption sleeve 11 sleeved on the outer wall of the filter plate 10 also rotates, further enhancing the adsorption capacity of harmful substances in the sludge sample and improving the uniformity of the enrichment effect.
