Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas collection pipe with a leakage alarm structure. Background Technology

[0002] Waste gas treatment systems refer to technical devices or engineering systems that use physical, chemical, or biological methods to purify harmful waste gases generated during industrial production, energy utilization, etc., so that they meet national or local emission standards before being released into the atmosphere. Their core objective is to reduce pollutant emissions, protect ambient air quality, and meet the compliant production needs of enterprises.

[0003] In existing technologies, a large number of waste gas collection pipes are used in waste gas treatment systems. These pipes are connected to various equipment or pipelines. Over a long period of use, waste gas leaks are prone to occur at the pipe connections. Because existing waste gas collection pipes lack effective gas detection and alarm structures, once a leak occurs, it is difficult for staff to detect and accurately locate the leak in a timely manner, which causes inconvenience to waste gas treatment work and increases the risk of environmental pollution caused by waste gas leaks.

[0004] Therefore, there is a need for an exhaust gas collection pipe with a leakage alarm structure to solve the problem that leakage easily occurs at the interface of the existing exhaust gas collection pipe and that it is not easy to quickly locate and investigate the leakage point. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas collection pipe with a leakage alarm structure to solve the problem that leakage easily occurs at the interface of the waste gas collection pipe in the prior art and it is not easy to quickly locate and investigate the leakage point.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas collection pipe with a leakage alarm structure, comprising a pipe body, wherein an installation mechanism is provided on the pipe body;

[0007] The installation mechanism includes an installation clamp and a limiting clamp mounted on the pipe body, two connecting rods rotatably mounted between the installation clamp and the limiting clamp, a slot opened inside the installation clamp, an operating box mounted on the installation clamp, sliding grooves opened on both sides inside the operating box, the same locking block slidably mounted inside the two sliding grooves, a screw rod rotatably mounted on the top surface of the locking block and threaded through the top surface of the operating box, an insert plate mounted on the limiting clamp and adapted to the slot, and several locking grooves opened on the insert plate and adapted to the locking block. An alarm component is provided on the top surface of the installation clamp.

[0008] It should be noted in the solution that the alarm component includes a mounting shell installed on the top surface of the mounting hoop, an exhaust fan installed inside the mounting shell with its input end extending to the outside of the mounting shell, a collection hood installed on the output end of the exhaust fan, a filter plate installed inside the collection hood, a detection chamber located inside the mounting shell, a gas detection device installed inside the detection chamber with its display screen located outside the mounting shell, a controller located inside the mounting shell, and an audible and visual alarm installed on the top surface of the mounting shell.

[0009] It is worth noting that a through groove is provided on the mounting hoop at the corresponding locking block position, and the locking block passes through the through groove and is inserted into one of the locking slots.

[0010] Furthermore, it should be noted that an exhaust vent is provided on one side of the mounting shell, and a dustproof plate is installed inside the exhaust vent.

[0011] In a preferred embodiment, the output end of the exhaust fan extends into the detection chamber, and the collection cover is precisely oriented towards the pipe body interface.

[0012] In a preferred embodiment, a through hole for venting is provided on one side of the detection chamber, and the controller is electrically connected to the gas detection device and the audible and visual alarm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By placing the mounting clamp on the pipe body and rotating the limiting clamp to insert the insert plate into the slot, the limiting clamp is made to fit the pipe body.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a pipe body 1, on which an installation mechanism 2 is provided;

[0023] The installation mechanism 2 includes an installation clamp 21 and a limiting clamp 22 mounted on the pipe body 1, two connecting rods 23 rotatably mounted between the installation clamp 21 and the limiting clamp 22, a slot 24 inside the installation clamp 21, an operating box 25 mounted on the installation clamp 21, sliding grooves 26 on both sides inside the operating box 25, a locking block 27 slidably mounted inside the two sliding grooves 26, a screw 28 rotatably mounted on the top surface of the locking block 27 and threaded through the top surface of the operating box 25, an insert plate 29 mounted on the limiting clamp 22 and adapted to the slot 24, and several locking grooves 210 on the insert plate 29 adapted to the locking block 27. An alarm component 3 is provided on the top surface of the installation clamp 21.

[0024] Specifically, after placing the mounting clamp 21 on the pipe body 1, rotate the limiting clamp 22 and insert the insert plate 29 into the slot 24 so that the limiting clamp 22 fits against the pipe body 1. Rotate the screw 28 to drive the locking block 27 into the locking groove 210 to lock the insert plate 29. With the interference fit, the mounting clamp 21 and the limiting clamp 22 are installed on the pipe body 1.

[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the alarm component 3 includes a mounting housing 31 mounted on the top surface of the mounting clamp 21, an exhaust fan 32 mounted inside the mounting housing 31 with its input end extending to the outside of the mounting housing 31, a collection cover 33 mounted on the output end of the exhaust fan 32, a filter plate 34 mounted inside the collection cover 33, a detection chamber 35 disposed inside the mounting housing 31, a gas detection device 36 disposed inside the detection chamber 35 with its display screen located outside the mounting housing 31, a controller 37 disposed inside the mounting housing 31, and an audible and visual alarm 38 mounted on the top surface of the mounting housing 31.

[0026] Specifically, in operation, the exhaust fan 32 continuously extracts the gas around the interface through the collection cover 33 facing the interface of the pipe body 1. The extracted gas is discharged into the detection chamber 35 and detected by the gas detection device 36. When the gas detection device 36 detects that the concentration of exhaust gas exceeds the preset threshold, it sends a signal to the controller 37. After receiving the signal, the controller 37 activates the audible and visual alarm 38 to remind the staff through both sound and light, so that the staff can quickly locate and investigate the leak.

[0027] Further as Figure 2 As shown, it is worth noting that a through groove 4 is provided on the mounting hoop 21 at the position corresponding to the locking block 27, and the locking block 27 passes through the through groove 4 and is inserted into one of the locking slots 210.

[0028] Specifically, when the rotating screw 28 moves the locking block 27, the locking block 27 passes through the through groove 4 and inserts into one of the locking grooves 210 to lock the insert plate 29. At the same time, it facilitates the installation of the mounting clamp 21 and the limiting clamp 22 with the pipe body 1 under interference fit, thereby realizing the installation of the alarm component 3 and making the installation mechanism 2 applicable to pipe bodies 1 of different specifications within a certain range.

[0029] Further as Figure 3 As shown, it is worth noting that an exhaust hole 5 is provided on one side of the mounting shell 31, and a dustproof plate 6 is installed inside the exhaust hole 5.

[0030] Specifically, the tested exhaust gas is discharged from the mounting housing 31 through the exhaust port 5, and the dustproof plate 6 is provided to prevent external dust from entering the mounting housing 31.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the output end of the exhaust fan 32 extends into the detection chamber 35, and the collection cover 33 is precisely oriented towards the interface of the pipe body 1.

[0032] Specifically, the output end of the exhaust fan 32 extends into the detection chamber 35, allowing the exhaust fan 32 to discharge the extracted gas into the detection chamber 35, enabling the gas detection device 36 to detect the extracted gas. The collection hood 33 is precisely oriented towards the interface of the pipe body 1, allowing the exhaust fan 32 to continuously extract the gas around the interface, forming a directional airflow environment, improving detection sensitivity, and facilitating accurate location of leaks by staff during troubleshooting.

[0033] Further as Figure 3 As shown, it is worth noting that a through hole for venting is provided on one side of the detection chamber 35, and the controller 37 is electrically connected to the gas detection device 36 and the audible and visual alarm 38.

[0034] Specifically, a through hole for exhaust is provided on one side of the detection chamber 35, so that the gas that has been detected flows out of the detection chamber 35 and is finally discharged from the mounting shell 31 through the exhaust hole 5. The controller 37 is electrically connected to the gas detection device 36 and the audible and visual alarm 38. When the gas detection device 36 detects that the concentration of exhaust gas exceeds the threshold, it sends a signal to the controller 37, and the controller 37 activates the audible and visual alarm 38 to sound an alarm.

[0035] In summary: When using this waste gas collection pipeline, firstly, install the pipeline body 1 onto the waste gas treatment equipment. Place the mounting clamp 21 onto the pipeline body 1 near the interface. Rotate the limiting clamp 22 via the connecting rod 23. Simultaneously, while rotating the limiting clamp 22, insert the insert plate 29 into the slot 24, making the limiting clamp 22 fit against the pipeline body 1. Then, rotate the screw 28. Under the action of the thread, the screw 28 gradually moves into the operating box 25, thereby pushing the locking block 27 towards the insert plate 29 under the action of the sliding groove 26. The locking block 27 passes through the through groove 4 and inserts into the locking groove 210, locking the insert plate 29. With the interference fit, the mounting clamp 21 and the limiting clamp 22 are installed on the pipeline body 1. Within a certain range, it can be applied to pipeline bodies 1 of different specifications. In the working state, the mounting shell 3... The input end of the internal exhaust fan 32 is precisely oriented towards the interface of the pipe body 1, continuously extracting the gas around the interface. When exhaust gas leaks at the interface of the pipe body 1, the exhaust fan 32 quickly draws in the leaking exhaust gas through the collection hood 33 and discharges it into the detection chamber 35 through the output end. The gas is then detected by the gas detection device 36. When the detected exhaust gas concentration exceeds the preset threshold, the gas detection device 36 sends an electrical signal to the controller 37. Upon receiving the signal, the controller 37 activates the audible and visual alarm 38, which emits an alarm through sound and light to alert the staff. It is easy to use and has sensitive detection, enabling rapid alarm while facilitating accurate location of the leak. This effectively avoids the problem that leaks are prone to occur at the interface of the exhaust gas collection pipe and that it is difficult to quickly locate and investigate the leak.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
