Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline gas detection, and particularly relates to an insertion-type pipeline exhaust air quality detection device. Background Technique

[0002] Directly detecting gas inside the pipeline can observe the change of gas concentration in real time, and timely discover and solve problems accordingly. The existing insertion-type gas detection devices have the following technical problems in the use process: 1) The installation and disassembly are relatively cumbersome, resulting in great difficulty in maintaining and replacing components. It is necessary to stop the machine or perform overall disassembly, which is time-consuming and laborious and affects the continuity of detection; 2) When inserting into the pipeline interior, no filtering device is added, resulting in dust and other particulate matters blocking the detection instrument and affecting the final detection result.

[0003] After retrieval, the prior art patent number: CN201510872488.1, the authorized announcement number: CN105344173B, a filter screen dust removal device, points out that: the air filter screen dust removal device in the prior art is as Figure 1 shown, including a dust removal motor 03 fixedly arranged on the indoor side surface of the air filter screen 01. The dust removal motor 03 has a motor shaft 02 extending out of the air filter screen 01 and located outdoors. A dust removal brush 04 is fixedly installed on the motor shaft 02, and the bristles of the dust removal brush 04 are in close contact with the outer side surface of the air filter screen 01. When dust removal is required, start the dust removal motor 03, the motor shaft 02 drives the brush 04 to rotate, and the bristles of the brush 04 rotate and clean the outer side surface of the air filter screen 01, and brush off the adhered dust.

[0004] After retrieval, the prior art CN220154384U discloses a device for detecting the air quality in a ventilation pipeline. A support rod is installed through the inner top wall of the pipeline. The bottom end of the support rod is installed with an installation ring. The inner top wall of the installation ring is installed with an air sensor, and the inner bottom wall of the installation ring is installed with a dust sensor. A fixed seat is installed on the top of the pipeline, and a control box is installed on the top of the fixed seat. The above technical solution is fixed to the support rod through the installation ring, air sensor and dust sensor, and the pipeline ensures the stability of the support rod. The support rod fixes the installation ring at the bottom end to ensure the stability of the installation ring. The installation ring fixes the air sensing dust sensor to ensure that the air sensor and the dust sensor can operate smoothly. The installation ring is horizontally placed inside the pipeline, facilitating the passage of internal gas and not blocking the movement of air, and facilitating the air sensor and the dust sensor to contact air; the above technical solution is extremely cumbersome in installation and disassembly during use, and during periodic maintenance, the entire gas transmission pipeline needs to be stopped before the overall disassembly can be carried out, which is time-consuming and laborious. It not only affects production, but also causes gas leakage during the disassembly and installation process, posing certain potential safety hazards.

[0005] For example, existing technology CN219675958U discloses a gas detector for pipelines. A snap-fit ​​disc is installed in the main body of the detector within a connecting pipe for docking with a pipeline opening. The snap-fit ​​assembly includes a sliding column, a connecting rod, and a snap-fit ​​handle. The sliding column slides up and down within the snap-fit ​​disc, and one end of the connecting rod is connected to the upper end of the sliding column. The upper end of the snap-fit ​​handle is hinged to the other end of the connecting rod, and the lower end of the snap-fit ​​handle snaps into the pipeline to be tested. A clamping assembly is provided between the connecting rod and the snap-fit ​​disc to drive the snap-fit ​​disc to press against the pipeline opening. A sealing gasket is provided on the lower side of the snap-fit ​​disc to contact the edge of the pipeline opening. In this device, by controlling the clamping assembly, the snap-fit ​​disc in the snap-fit ​​assembly can be pressed downwards against the pipeline opening on the pipeline to be tested, temporarily connecting the detection body with the pipeline. Compared to traditional detectors that use threaded connections, this greatly simplifies the installation and disassembly process. However, during use, the detector body is easily affected by dust and other particles, leading to larger detection errors. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an insert-type pipeline exhaust air quality detection device. By setting up a lifting bracket to drive the filter screen to reciprocate, it can not only filter particulate matter such as dust, but also use conical rubber to complete the internal sealing, so that there is no need for excessive disassembly. The maintenance of the components can be completed by opening part of the shell, and there is no risk of gas leakage. In addition, a brush is added to the outside of the filter screen to rotate and clean, ensuring the air permeability of the filter screen at all times, which greatly improves the overall stability.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An insertable pipeline air quality detection device includes a fixing clamp I, a fixing clamp II, a housing, an electric telescopic rod, a lifting bracket, a filter screen, a conical rubber, a rotating bracket, a brush, an external gear ring, a gear, a motor, a mounting plate, an air pipe, a hose, a gas analyzer, a conical cylinder, a locking plate, and a locking hole. The fixing clamp I and fixing clamp II are bolted to the opening of the air supply pipe and aligned with the opening of fixing clamp I. The opening of fixing clamp I is connected to the housing via a conical cylinder. A lifting bracket is movably installed inside the housing. The lifting bracket is equipped with a filter screen, a conical rubber at its bottom, and an electric telescopic rod fixedly connected to its top. One end of the electric telescopic rod is fixedly installed on the inner side wall of the top of the housing. A rotating bracket is fitted on the outer side of the lifting bracket. Several brushes are provided on the inner side of the rotating bracket. An external gear ring is provided on the top of the rotating bracket. The external gear ring is meshed with a gear and is movably connected. The gear is movably installed in the housing. One end of the gear's central shaft is fixedly connected to the motor output end. The motor is fixedly installed on the housing. A locking buckle is provided on the inner side of the lifting bracket. A mounting plate is provided inside the locking buckle. Locking plates are provided on both sides of the mounting plate. Locking holes are opened on the locking plates. An air pipe is provided in the center of the mounting plate. One end of the air pipe is open, and the other end is connected to a flexible hose. The other end of the flexible hose passes through the housing's sealing tube and is connected to the gas analyzer.

[0009] A limit pin is movably installed in the through hole of the locking buckle, and a spring is provided between the limit pin and the side wall of the lifting bracket.

[0010] One end of the limiting pin is equipped with a lever for easy operation by staff, and the other end is a tapered head for better entry into the locking hole.

[0011] The mounting plate is equipped with a handle, which makes it convenient for staff to lift and lock the device.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1) By controlling the extension of the electric telescopic rod, the lifting bracket drives the conical rubber to detach from the conical cylinder and penetrate into the gas delivery pipe. At this time, the gas needs to pass through the filter screen to filter dust particles before it can be drawn in through the internal air pipe and delivered to the gas analyzer for gas analysis through the hose. When gas analysis is not required, the electric telescopic rod can be controlled to retract, causing the lifting bracket to drive the conical rubber back to the conical cylinder. At this time, the conical rubber completes the sealing effect, and the gas will not enter the housing, protecting the internal components from the influence of exhaust gas, extending the service life of the components, and making it easier for staff to open one side of the housing to inspect and replace the internal components without excessive disassembly and assembly, simplifying the maintenance steps, reducing the labor intensity of the staff, and eliminating the risk of gas leakage.

[0014] 2) After the filter screen has been working for a period of time, the motor can be started to drive the gear to rotate, which in turn drives the rotating bracket to rotate through the meshing transmission of the outer gear ring. This allows the inner brush to brush the surface of the filter screen. The design of the long gear allows the lifting bracket to clean the filter screen regardless of its position. When it goes deep into the air pipe, the dust particles will be sucked back into the internal pipe under wind pressure, which greatly improves the air permeability of the filter screen, extends the maintenance cycle, and ensures the accuracy of gas detection.

[0015] 3) By moving the limit pin upward to compress the spring, the locking plates on both sides of the mounting plate can be rotated under the locking buckle. After reaching the designated position, the limit pin is released. At this time, under the action of the spring, the limit pin passes through the locking hole on the locking plate to complete the locking limit. The locking of the limit pin can prevent the mounting plate from shifting, improve the airtightness, prevent it from falling off due to resonance, and make the equipment adaptable to complex and upside-down installation environments, greatly improving its reliability and adaptability.

[0024] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figures 1-7 The technical solution of this utility model will be further described in detail below.

[0025] An insertable pipeline air quality detection device includes a fixing clamp I 11, a fixing clamp II 12, a housing 13, an electric telescopic rod 14, a lifting bracket 15, a filter screen 16, a conical rubber 17, a rotating bracket 18, a brush 19, an external gear ring 20, a gear 21, a motor 22, a mounting plate 23, an air pipe 24, a flexible hose 25, a gas analyzer 26, a conical cylinder 131, a locking plate 231, and a locking hole 232. The fixing clamp I 11 and fixing clamp II 12 are bolted to the opening of the air supply pipe 10 and aligned with the opening of fixing clamp I 11. The opening of fixing clamp I 11 is connected to the housing 13 through the conical cylinder 131. The lifting bracket 15 is movably installed inside the housing 13, and the lifting bracket 15 is equipped with a filter screen 16. 6. The bottom of the lifting bracket 15 is provided with a conical rubber 17, and one end of the electric telescopic rod 14 is fixedly connected to the top. The other end of the electric telescopic rod 14 is fixedly installed on the inner side wall of the top of the housing 13. A rotating bracket 18 is sleeved on the outside of the lifting bracket 15. Several brushes 19 are provided on the inner side of the rotating bracket 18. An external gear ring 20 is provided on the top of the rotating bracket 18. The external gear ring 20 is meshed and movably connected with a gear 21. The gear 21 is movably installed in the housing 13. One end of the central shaft of the gear 21 is fixedly connected to the output end of the motor 22. The motor 22 is fixedly installed on the housing 13. A locking buckle 151 is provided on the inner side of the lifting bracket 15. A mounting plate 23 is provided inside the locking buckle 151. Locking plates 231 are provided on both sides of the mounting plate 23. Locking holes 2 are provided on the locking plates 231. 32. An air pipe 24 is located at the center of the mounting plate 23. One end of the air pipe 24 is open, and the other end is connected to a flexible hose 25. The other end of the flexible hose 25 passes through the sealed tube of the housing 13 and connects to the gas analyzer 26. The gas analyzer 26 is model VXV100-02 (which can be obtained through private customization or direct purchase). By controlling the extension of the electric telescopic rod 14, the lifting bracket 15 drives the conical rubber 17 to detach from the conical cylinder 131 and penetrate into the gas delivery pipe 10. At this time, the gas needs to pass through the filter screen 16 to filter dust particles before it can be drawn in through the internal air pipe 24 and delivered to the gas analyzer 26 for gas analysis through the flexible hose 25. When gas analysis is not required, the electric telescopic rod 14 can be controlled to retract, causing the lifting bracket 15 to drive the conical rubber 17 to detach from the conical cylinder 131 and penetrate into the gas delivery pipe 10. When the rubber 17 returns to the conical cylinder 131, the conical rubber 17 completes the sealing effect, preventing gas from entering the housing 13 and protecting the internal components from the influence of exhaust gas, thus extending the service life of the components and facilitating the maintenance and replacement of internal components by opening one side of the housing. After the filter screen 16 has been working for a period of time, the motor 22 can be started to drive the gear 21 to rotate, thereby driving the rotating bracket 18 to rotate through the meshing transmission of the outer gear ring 20, so that the inner brush 19 can perform a brushing operation on the surface of the filter screen 16. The design of the long gear allows the lifting bracket 15 to clean the filter screen 16 regardless of its position. When it penetrates into the air supply pipe 10, the dust particles will be sucked back into the internal pipe under wind pressure.

[0026] A limiting pin 152 is movably installed in the through hole of the locking buckle 151. A spring 154 is provided between the limiting pin 152 and the side wall of the lifting bracket 15. By moving the limiting pin 152 upward to compress the spring 154, the locking plates 231 on both sides of the mounting plate 23 can be rotated under the locking buckle 151. After reaching the designated position, the limiting pin 152 is released. At this time, under the action of the spring 154, the limiting pin 152 passes through the locking hole 232 on the locking plate 231 to complete the locking limit.

[0027] The limiting pin 152 has a lever 153 at one end for easy operation by staff, and a tapered head at the other end for better entry into the locking hole 232.

[0028] The mounting plate 23 is equipped with a handle 233, which facilitates the lifting and locking operation by the staff.

[0029] An insert-type pipeline air quality detection device operates as follows: First, a hole is drilled in the gas supply pipe 10 to be tested. Then, fixing clamps I 11 and II 12 are installed on the gas supply pipe 10 using bolts. Next, the electric telescopic rod 14 is extended, causing the lifting bracket 15 to detach the conical rubber 17 from the conical cylinder 131 and penetrate into the gas supply pipe 10. At this point, the gas must pass through the filter screen 16 to filter dust particles before being drawn in through the internal air pipe 24 and delivered to the gas analyzer 26 for analysis via the hose 25. When gas analysis is not required, the electric telescopic rod 14 is retracted, causing the lifting bracket 15 to return the conical rubber 17 to the conical cylinder 131. 1. At this time, the conical rubber 17 completes the sealing effect, and the gas will not enter the interior of the housing 13, protecting the internal components from the influence of exhaust gas, improving the service life of the components, and making it convenient for the staff to open one side of the housing to inspect and replace the internal components. After the filter screen 16 has been working for a period of time, the motor 22 can be started to drive the gear 21 to rotate, thereby driving the rotating bracket 18 to rotate through the meshing transmission of the outer gear ring 20, so that the inner brush 19 can perform a brushing operation on the surface of the filter screen 16. The design of the long gear allows the lifting bracket 15 to clean the filter screen 16 regardless of its position. When it penetrates into the air supply pipe 10, the dust particles will be sucked back into the internal pipe under wind pressure.
