Description

Technical Field

[0001] This utility model belongs to the field of wastewater detection technology, and in particular relates to a municipal pipeline wastewater detection device. Background Technology

[0002] Municipal pipelines, as a crucial component of urban infrastructure, promptly drain rainwater from urban surfaces, providing industrial and domestic water supply while preventing urban water pollution. Municipal pipeline projects include water supply pipelines, drainage pipelines, gas pipelines, and heating pipelines. Among these, drainage pipelines are primarily used to collect urban sewage, industrial wastewater, and rainwater in a timely manner, transporting sewage and industrial wastewater to wastewater treatment plants for treatment before discharge.

[0003] After a long period of drainage work, municipal pipelines often accumulate a large amount of dirt inside, which affects water quality. Therefore, it is necessary to test the sewage in municipal pipelines regularly. Before testing, sewage samples need to be taken from the pipes. Currently, there are some pipeline sewage testing and sampling equipment on the market. For example, a pipeline sewage sampling device is disclosed on the China Patent Network, with the publication number CN218098448U. This device can be used for sewage testing and sampling in municipal pipelines, but it has some defects and shortcomings that need to be improved: (1) Due to the structural design of the existing testing and sampling equipment, it is difficult to divide the sewage into multiple water samples and store them when sampling the sewage in the pipeline, which makes it inconvenient to send the water samples to relevant departments for sewage testing of multiple different projects; (2) Most of the existing testing and sampling equipment lacks effective filtration measures, and the sewage in the pipeline often contains some solid impurities such as mud, sand, and hair. The existing testing and sampling equipment is difficult to filter these solid impurities when sampling, which can easily cause the equipment to become blocked; (3) The existing testing and sampling equipment lacks corresponding pressure relief measures. After the pipeline sewage sampling work is completed, it is difficult to relieve the pressure in time, and the sewage will continue to flow into the equipment, which will not only cause the collected and stored water samples to overflow, but also cause the equipment to malfunction due to excessive internal water pressure. Therefore, the municipal pipeline sewage detection device provided by this utility model is of great significance in addressing the above problems. Utility Model Content

[0004] This utility model provides a municipal pipeline sewage testing device. It collects and preserves sewage samples from municipal pipelines using sampling bottles for subsequent testing. During sewage sampling, multiple sampling tubes divide the sewage into multiple water samples, each of which is then stored separately in multiple sampling bottles. This allows for convenient delivery of multiple samples to relevant departments for various sewage testing projects, significantly improving the efficiency of the entire testing process. The filter screen in the filter element covers and blocks the sampling port. When sampling wastewater, a filter screen can be used to filter out solid impurities such as mud, sand, and hair, effectively preventing clogging of the detection device. The pressure relief port can be sealed by the sealing cover and sealing plug in the pressure relief component. When wastewater continuously flows into the sampling chamber and increases the internal water pressure of the detection device, the wastewater in the sampling chamber can push open the sealing cover and overflow along the pressure relief channel and each pressure relief hole, thus achieving automatic pressure relief. This effectively prevents the detection device from malfunctioning due to excessive internal water pressure, thereby solving the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a municipal pipeline sewage testing device, comprising a pipe body, an installation cylinder installed at one end of the pipe body, the installation cylinder being cylindrical with several threaded holes on its wall, bolts being threaded into the threaded holes, a positioning block being fixedly connected to one side of the installation cylinder near the pipe body, and a sampling chamber being fixedly connected to the other side of the installation cylinder, the positioning block having a circular cross-section with a sampling port at its center, and a filter element being installed on the positioning block, the sampling chamber having a circular cross-section, a hollow internal structure communicating with the sampling port, and several sampling tubes being fixedly connected to the side wall of the sampling chamber, each sampling tube having a sampling bottle installed at its end, a pressure relief port being provided on one side of the sampling chamber, and a pressure relief element being installed on the pressure relief port.

[0007] Furthermore, the threaded holes are arranged in a circular array around the mounting cylinder, and each bolt has an anti-slip pad on its end surface. The anti-slip pad is a circular rubber pad with herringbone anti-slip patterns engraved on its surface.

[0008] Furthermore, the diameter of the positioning block is equal to the inner diameter of the tube, and a sealing ring is provided on the side wall surface of the positioning block. The sealing ring is a rubber ring structure. Several studs are fixedly connected to the surface of the positioning block. The studs are arranged in a ring array with the positioning block as the center, and each stud is threaded with a nut that matches it.

[0009] Furthermore, the filter element includes a filter plate, which is circular and has several mounting holes on its surface. A filter screen is installed at the center of the filter plate. The filter screen is circular and its diameter is larger than the diameter of the sampling port. The number of mounting holes is the same as that of the studs, and the hole diameter is equal to that of the studs. The center of each mounting hole corresponds to the center of each stud.

[0010] Furthermore, the sampling tube is L-shaped and arranged in a ring array around the sampling chamber. One end of the tube is connected to the sampling chamber, and the outer wall of the other end of the sampling tube and the inner wall of the sampling bottle are respectively engraved with mutually matching external and internal threads.

[0011] Furthermore, each of the sampling tubes is equipped with a one-way valve.

[0012] Furthermore, the pressure relief component includes a sealing cap, which is circular with a diameter larger than the outer diameter of the pressure relief port. A sealing plug is fixedly connected to the sealing cap, which is also circular with a diameter equal to the inner diameter of the pressure relief port. A pressure relief channel and several pressure relief holes are respectively opened at the center and sidewall of the sealing plug, and each pressure relief hole is connected to the pressure relief channel. Several through holes are opened on the surface of the sealing cap, and a guide rod is inserted into each through hole. One end of the guide rod is fixedly connected to a protrusion, and the other end is fixedly connected to the sampling chamber. A spring is wound around the body of the guide rod, and the two ends of the spring are fixedly connected to the protrusion and the sealing cap, respectively.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) When the detection device of this utility model is used, it can collect and preserve sewage samples in municipal pipelines through sampling bottles so as to conduct subsequent testing on the water samples. When sampling sewage, the sewage can be divided into multiple water samples through multiple sampling tubes, and each water sample can be preserved separately through multiple sampling bottles. Thus, it is very convenient to send multiple water samples to relevant departments for sewage testing of multiple different items, thereby greatly improving the efficiency of the entire testing work.

[0015] (2) When the detection device of this utility model is used, the sampling port can be covered and blocked by the filter screen in the filter element. When sampling sewage, the filter screen can filter solid impurities such as mud and hair in the sewage, thereby effectively preventing the detection device from being blocked.

[0016] (3) When the detection device of this utility model is in use, the pressure relief port can be sealed by the sealing cover and sealing plug in the pressure relief component. When sewage is continuously poured into the sampling chamber and the internal water pressure of the detection device increases, the sewage in the sampling chamber can push open the sealing cover and overflow along the pressure relief channel and each pressure relief hole to play the role of automatic pressure relief, thereby effectively preventing the detection device from malfunctioning due to excessive internal water pressure.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-8 As shown, this utility model discloses a municipal pipeline sewage testing device, comprising a pipe body 1, with an installation cylinder 2 installed at one end of the pipe body 1. The installation cylinder 2 is cylindrical, and its wall has several threaded holes 3. Bolts 4 are threaded into the threaded holes 3. The installation cylinder 2 can be fitted against the pipe opening at one end of the pipe body 1. At this time, the bolts 4 in each threaded hole 3 are tightened, so that the ends of each bolt 4 are tightly pressed against the outer wall of the pipe body 1. The bolts 4 can provide a fastening effect, so that the installation cylinder 2 and the testing device are fixed together on the pipe body 1. A positioning block 5 is fixedly connected to the side of the installation cylinder 2 near the pipe body 1, and a sampling chamber 6 is fixedly connected to the other side. The horizontal... The cross-section is circular, with a sampling port 7 at its center. A filter is installed on the positioning block 5. The sampling chamber 6 has a circular cross-section and a hollow internal structure that is connected to the sampling port 7. Several sampling tubes 8 are fixedly connected to the side wall of the sampling chamber 6. A sampling bottle 9 is installed at the end of each sampling tube 8. When the detection device is installed on the tube body 1, the sewage in the tube can enter the sampling chamber 6 through the sampling port 7 and enter each sampling bottle 9 through each sampling tube 8. The sewage sample can be collected and preserved through the sampling bottle 9 for subsequent testing of the water sample. A pressure relief port 10 is opened on one side of the sampling chamber 6, and a pressure relief component is installed on the pressure relief port 10.

[0032] The threaded holes 3 are arranged in a ring array around the mounting cylinder 2. Each bolt 4 has an anti-slip pad 11 on its end surface. The anti-slip pad 11 is a circular rubber pad with herringbone anti-slip patterns on its surface. When the end of the bolt 4 is pressed tightly against the outer wall of the tube body 1, the anti-slip patterns on the surface of the anti-slip pad 11 can increase the friction between the bolt 4 and the tube body 1, thereby playing an anti-slip role and improving the fastening effect of the bolt 4. This prevents the detection device from slipping and loosening after installation. At the same time, the rubber anti-slip pad 11 can also play a certain anti-wear protection role to avoid direct contact between the surface of the tube body 1 and the bolt 4 and cause wear.

[0033] The diameter of the positioning block 5 is equal to the inner diameter of the pipe body 1, and a sealing ring 12 is provided on the side wall surface of the positioning block 5. The sealing ring 12 is a rubber ring structure with a certain elasticity. When the installation cylinder 2 is fixed at one end of the pipe body 1, the positioning block 5 can be inserted and fit against the inner wall of the pipe body 1. At this time, the positioning block 5 can play a positioning role to further improve the stability of the installation cylinder 2 after installation and prevent it from loosening. At the same time, the sealing ring 12 can fill the gap between the positioning block 5 and the inner wall of the pipe body 1 to prevent sewage in the pipe body 1 from overflowing through the gap and affecting the sampling. Several studs 13 are fixedly connected to the surface of the positioning block 5. The studs 13 are distributed in a ring array with the positioning block 5 as the center, and each stud 13 is threaded with a nut 14 that matches it.

[0034] The filter element includes a filter plate 15, which is circular and has several mounting holes 16 on its surface. A filter screen 17, which is also circular and has a diameter larger than that of the sampling port 7, is installed at the center of the filter plate 15. The number of mounting holes 16 is the same as that of the studs 13, and their diameters are equal to those of the studs 13. The center of each mounting hole 16 corresponds to the center of each stud 13. Each stud 13 can be aligned and pass through the corresponding mounting hole 16. At this time, the nuts 14 are threaded onto each stud 13. The filter plate 15 is fixedly installed on the positioning block 5 through the mutual cooperation between the studs 13 and the nuts 14. When the filter plate 15 is installed on the positioning block 5, the filter screen 17 can cover and block the sampling port 7. At this time, the filter screen 17 can filter solid impurities such as mud, sand and hair in the sewage to effectively prevent the detection device from clogging. After the filter element has been used for a long time, the filter plate 15 can be removed by unscrewing the nuts 14 to clean the filter screen 17.

[0035] The sampling tube 8 is L-shaped and arranged in a ring array around the sampling chamber 6. One end of the tube is connected to the sampling chamber 6, and the outer wall of the other end of the sampling tube 8 and the inner wall of the sampling bottle 9 are respectively engraved with matching external and internal threads. Multiple sampling bottles 9 can be installed at the end of the corresponding sampling tube 8 through threaded connection. When sampling sewage, the sewage can be divided into multiple water samples through multiple sampling tubes 8, and each water sample can be stored separately through multiple sampling bottles 9. This makes it easy to send multiple water samples to relevant departments for sewage testing of multiple different projects, thereby greatly improving the efficiency of the entire testing work.

[0036] Each sampling tube 8 is equipped with a one-way valve 18. The one-way valve 18 has one-way conduction. When the water sample enters the corresponding sampling bottle 9 along the sampling tube 8, it can no longer flow out of the sampling bottle 9, thus effectively preventing the water sample stored in the sampling bottle 9 from flowing back and overflowing.

[0037] The pressure relief component includes a sealing cover 19, which is circular with a diameter larger than the outer diameter of the pressure relief port 10. A sealing plug 20 is fixedly connected to the sealing cover 19. The sealing plug 20 is circular with a diameter equal to the inner diameter of the pressure relief port 10. A pressure relief channel 21 and several pressure relief holes 22 are respectively opened at the center and side wall of the sealing plug 20. Each pressure relief hole 22 is connected to the pressure relief channel 21. Several through holes 23 are opened on the surface of the sealing cover 19. A guide rod 24 is inserted into each through hole 23. One end of the guide rod 24 is fixedly connected to a protrusion, and the other end is fixedly connected to the sampling chamber 6. A spring 25 is wound around the body of the guide rod 24. The two ends of the spring 25 are fixedly connected to the protrusion and the sealing cover 19, respectively. Under the elastic restoring action of the spring 25, the sealing cover 19 can fit tightly against the pressure relief port 10. At port 0, the sealing plug 20 can be inserted and adhered to the inner wall of the pressure relief port 10 to seal it, thereby preventing the sewage in the sampling chamber 6 from overflowing through the pressure relief port 10. When sewage continues to flow into the sampling chamber 6 and increases the internal water pressure of the detection device, the sealing cover 19 will be pushed open by the water pressure and compress the spring 25. When the sealing cover 19 is pushed open, the sealing plug 20 will extend from the pressure relief port 10. At this time, the sewage in the sampling chamber 6 can overflow along the pressure relief channel 21 and each pressure relief hole 22 to achieve automatic pressure relief, thereby effectively preventing the detection device from malfunctioning due to excessive internal water pressure. After the excess sewage in the sampling chamber 6 is discharged, the sealing cover 19 will re-adhere to the port of the pressure relief port 10 under the elastic reset action of the spring 25 to seal the pressure relief port 10.

[0038] The working principle of this utility model is as follows:

[0039] When using this invention, to test sewage in municipal pipelines, the mounting cylinder 2 can be attached to one end of the pipe body 1, and then the bolts 4 in each threaded hole 3 can be tightened, ensuring that the ends of each bolt 4 are firmly against the outer wall of the pipe body 1. The bolts 4 provide a fastening effect, fixing the mounting cylinder 2 and the testing device together onto the pipe body 1. When the testing device is installed on the pipe body 1, sewage in the pipe can enter the sampling chamber 6 through the sampling port 7, and then enter each sampling bottle 9 through each sampling tube 8. Sewage samples can then be collected and preserved through the sampling bottles 9 for subsequent testing. During sewage sampling, multiple sampling tubes 8 can divide the sewage into multiple water samples, and each water sample can be preserved separately through multiple sampling bottles 9, making subsequent testing much more convenient. This allows for the convenient delivery of multiple water samples to relevant departments for wastewater testing of various projects, thereby greatly improving the efficiency of the entire testing process. When sampling wastewater, the filter screen 17 on the filter plate 15 can cover and block the sampling port 7. At this time, the filter screen 17 can filter solid impurities such as mud and hair in the wastewater, effectively preventing the testing device from becoming clogged. When wastewater continuously flows into the sampling chamber 6 and increases the internal water pressure of the testing device, the sealing cover 19 will be pushed open under the water pressure and compress the spring 25. When the sealing cover 19 is pushed open, the sealing plug 20 will extend from the pressure relief port 10. At this time, the wastewater in the sampling chamber 6 can overflow along the pressure relief channel 21 and each pressure relief hole 22 to achieve automatic pressure relief, thereby effectively preventing the testing device from malfunctioning due to excessive internal water pressure.
