Description

Technical Field

[0001] This utility model relates to the field of VOCs detection equipment technology, and in particular to an explosion-proof VOCs fugitive leakage locating device. Background Technology

[0002] In industrial production processes such as petroleum, chemical, and pharmaceutical manufacturing, fugitive leaks of volatile organic compounds (VOCs) occur frequently. These substances not only pollute the environment but are also mostly flammable and explosive, posing significant safety hazards in explosion-proof areas.

[0003] Currently, VOCs detection devices are typically installed to monitor such leaks. However, many existing detection devices are fixed installations, with sensors fixed in specific locations and orientations.

[0004] This fixed design leads to serious technical drawbacks: when a leak occurs, the sensor's detection range is extremely limited, covering only a small area directly in front of it, resulting in numerous blind spots. Especially in complex operating conditions with dense pipelines and flanges, fixed-angle sensors struggle to scan and accurately locate leak sources, making leak point investigation difficult, resulting in low precision in location, and failing to meet the need for rapid leak source identification.

[0005] Therefore, this utility model proposes an explosion-proof VOCs fugitive leakage locating device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed sensor installation angle, limited detection range and low positioning accuracy in the existing explosion-proof VOCs fugitive leakage locating device, this utility model aims to provide an explosion-proof VOCs fugitive leakage locating device with improved structure that can effectively solve the above problems.

[0007] This utility model provides an explosion-proof VOCs fugitive leakage locating device, including an adjusting mechanism with a fixed plate and a placement plate rotatably disposed above the fixed plate. The adjusting mechanism also includes a motor fixedly connected to the fixed plate and a rotating assembly connected between the motor and the placement plate. The rotating assembly, as the core transmission structure, includes a fixed seat fixedly connected to the lower surface of the placement plate, and a rotating shaft rotatably connected within the fixed seat; the rotating shaft is drively connected to the output shaft of the motor. The rotating assembly also includes a connecting rod fixedly connected to the rotating shaft, a swing shaft rotatably connected to the end of the connecting rod away from the rotating shaft, and a second connecting rod. One end of the second connecting rod is rotatably connected to the end of the swing shaft away from the first connecting rod, and the other end is rotatably connected to the fixed plate. By driving the rotating shaft with the motor, and through the linkage mechanism composed of the first connecting rod, the swing shaft, and the second connecting rod, the fixed seat and the placement plate fixed thereto are ultimately rotated.

[0008] Preferably, the adjusting mechanism further includes a hydraulic rod fixedly connected to the fixed plate, and a movable plate slidably connected to the underside of the placement plate. The movable plate is slidably mounted on the support second, and the piston rod end of the hydraulic rod is connected to the movable plate, used to move the movable plate under the drive of the hydraulic rod, thereby selectively restricting or releasing the rotation of the placement plate.

[0009] Preferably, the adjustment mechanism further includes a support one fixed to the fixed plate, and a limiting rod passing through the support one and the fixed plate one. The connecting rod two is rotatably connected inside the support one, and the limiting rod plays a key guiding role when the plate rotates, ensuring the smoothness of the rotation.

[0010] Preferably, the device further includes a sensor and a quick-release mechanism for detachably connecting the sensor to the placement plate. The quick-release mechanism includes a housing one fixedly connected to the side wall of the sensor, and a housing two fixedly connected to the placement plate and mating with the housing one.

[0011] Preferably, the quick-release mechanism further includes a second movable rod and a first movable rod that slide through the first housing and the second housing respectively, and includes a second spring rod and a first spring rod that are used to drive the second movable rod and the first movable rod to elastically reset respectively.

[0012] Preferably, the quick-release mechanism further includes a second limiting seat and a first limiting seat disposed on the first housing. One end of the second moving rod and the first moving rod are respectively formed as a semi-circle, and the semi-circles cooperate with the second limiting seat and the first limiting seat respectively, so as to be locked in the limiting seat when the second spring rod and the first spring rod are reset, thereby achieving a firm lock.

[0013] Preferably, the quick-release mechanism further includes a fixed base two fixed to the housing one. One end of the spring rod two is connected to the movable rod two, and the other end is fixed to the fixed base two, providing a reliable return force for the movable rod two.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the technical problems of fixed sensor installation angle, limited detection range, and low positioning accuracy in the prior art by setting an adjustment mechanism consisting of a rotating component driven by a motor and a placement plate. It achieves the technical effect of enabling the sensor to rotate at multiple angles, expanding the detection range, and improving the precision of leak location.

[0015] 2. This utility model solves the technical problems of complicated replacement and inconvenient maintenance of sensors damaged by high and low temperature environments in the prior art by setting up a quick-release mechanism composed of a housing, a housing, a moving rod, a spring rod and a limiting seat. It achieves the technical effect of quick sensor disassembly and installation, greatly improving the convenience of replacement and maintenance efficiency.

[0016] 3. This utility model solves the problem of potential shaking or angle instability of the sensor during the adjustment process by adding a hydraulic rod and a moving plate to the adjustment mechanism to lock the placement plate, and setting a limit rod to guide the rotating component. It achieves the technical effect of ensuring a smooth adjustment process, reliable position locking after adjustment, and further improving the detection stability. Attached Figure Description

[0019] Example: Reference Figures 1 to 5 This utility model provides an explosion-proof VOCs fugitive leakage locating device, which aims to solve the problems of limited sensor detection range, low positioning accuracy, and inconvenient replacement and maintenance of sensors after damage in harsh environments in existing VOCs leakage detection devices.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the explosion-proof VOCs fugitive leakage locating device includes an adjustment mechanism 2 and a sensor 1 detachably connected to the adjustment mechanism 2 via a quick-release mechanism 3. The adjustment mechanism 2 is used to support and adjust the detection angle of the sensor 1. The adjustment mechanism 2 includes a fixed plate 21 as a mounting base and a placement plate 26 rotatably disposed above the fixed plate 21. The placement plate 26 is used to support the quick-release mechanism 3. To realize the rotation of the placement plate 26, the adjustment mechanism 2 further includes a motor 22 fixedly connected to the fixed plate 21 and a rotating assembly 23 connected between the motor 22 and the placement plate 26. The output shaft of the motor 22 is drively connected to the rotating assembly 23 to drive the placement plate 26 to rotate. Specifically, the rotating assembly 23 includes a fixedly connected... The lower surface of the placement plate 26 has a fixed seat 231, a rotating shaft 232 rotatably connected inside the fixed seat 231, a connecting rod 233 fixedly connected to the rotating shaft 232, a swing shaft 234 rotatably connected to the end of the connecting rod 233 away from the rotating shaft 232, and a connecting rod 235. One end of the connecting rod 235 is rotatably connected to the end of the swing shaft 234 away from the connecting rod 233, and the other end of the connecting rod 235 is rotatably connected to a support 236 fixed on the fixed plate 21. The output shaft of the motor 22 is connected to the rotating shaft 232 for transmission. Thus, the motor 22 drives the rotating shaft 232, the connecting rod 233, the swing shaft 234 and the connecting rod 235 to rotate in sequence, ultimately causing the fixed seat 231 and the placement plate 26 fixed thereto to rotate.

[0021] Reference Figure 2 , Figure 4 and Figure 5 The adjustment mechanism 2 includes a hydraulic rod 24 fixedly connected to the fixed plate 21 and a movable plate 25 slidably connected to the bottom of the placement plate 26. The movable plate 25 is slidably mounted on the support 27, which is fixed to the fixed plate 21. The piston rod end of the hydraulic rod 24 is connected to the movable plate 25. Its function is to drive the movable plate 25 to move through the extension and retraction of the hydraulic rod 24. The movement of the movable plate 25 is used to selectively restrict or release the rotation of the placement plate 26. This cooperation method ensures the positional stability of the placement plate 26 in the non-adjustment state through the engagement and disengagement of the guide structure on the movable plate 25 and the fixed column on the side wall of the placement plate 26. To further improve the smoothness of the rotation process of the placement plate 26, the adjustment mechanism 2 also includes a limiting rod 28 that passes through the support 236 and the fixed seat 231. When the placement plate 26 rotates, the limiting rod 28 provides a guiding function for the fixed seat 231, thereby preventing the placement plate 26 from shaking or tilting unnecessarily during the rotation process.

[0022] Reference Figure 1 , Figure 2 and Figure 3The quick-release mechanism 3 is used to detachably connect the sensor 1 and the placement plate 26. The quick-release mechanism 3 includes a housing 31 fixedly connected to the side wall of the sensor 1, and a housing 32 fixedly connected to the placement plate 26 and mating with the housing 31. To achieve locking and separation, the quick-release mechanism 3 also includes a second moving rod 37 and a first moving rod 35 that slide through the housing 31 and housing 32 respectively, and a second spring rod 38 and a first spring rod 36 that drive the second moving rod 37 and the first moving rod 35 to elastically reset. More specifically, the quick-release mechanism 3 also includes a second limiting seat 34 on the housing 31 and a first limiting seat 33 on the housing 32. One end of the second movable rod 37 and the first movable rod 35 are respectively formed as semicircles. The semicircles cooperate with the second limit seat 34 and the first limit seat 33 respectively, and are used to lock into the spring rod 38 and the first spring rod 36 when they are reset, thereby firmly locking the housing 31 and the housing 32 together. In order to provide a reliable elastic reset force, the quick release mechanism 3 also includes a second fixed seat 39 fixed on the housing 31. One end of the second spring rod 38 is connected to the second movable rod 37, and the other end is fixed to the second fixed seat 39. In addition, in order to ensure the accuracy of docking and the stability of connection, a fixed rod is installed on the inner wall of the housing 32, and a groove that cooperates with the fixed rod is opened inside the housing 31.

[0023] The working principle is as follows: When the detection angle of sensor 1 needs to be adjusted, the motor 22 and hydraulic rod 24 fixed above the fixed plate 21 are activated. The hydraulic rod 24 extends and pushes the moving plate 25. The moving plate 25 slides within the guide plate above the support 27, thereby releasing the locking restriction on the fixed column on one side of the placement plate 26. At the same time, the motor 22 rotates, driving the rotating shaft 232 in the rotating assembly 23 to rotate through the transmission mechanism. The rotation of the rotating shaft 232 is transmitted to the connecting rod 235 via the first connecting rod 233 and the swing shaft 234. The second 235 is rotatably connected to the fixed support 236. The linkage of the entire linkage mechanism ultimately drives the placement plate 26, which is fixed to the fixed base 231, to rotate to a new angle. During this process, the limit rod 28 always passes through the support 236 and the fixed base 231, providing stable guidance for the rotation of the placement plate 26. After the adjustment is in place, the hydraulic rod 24 retracts, the moving plate 25 moves in the opposite direction and relocks the placement plate 26. Through this series of coordinated actions, the sensor 1 achieves multi-angle fine adjustment and expands the detection range.

[0024] When sensor 1 needs to be replaced, operate the quick-release mechanism 3 and manually press the first moving rod 35 and the second moving rod 37 to make them slide against the elastic force of the first spring rod 36 and the second spring rod 38. This action causes the semi-circular ends of the first moving rod 35 and the second moving rod 37 to rotate in the first limiting seat 33 and the second limiting seat 34 respectively, thereby releasing the jamming state of the first housing 31 and the second housing 32. At this time, sensor 1 with housing 31 attached can be separated from housing 32 fixed on the placement plate 26. During installation, the operation is reversed. After aligning housing 31 and housing 32, release the moving rod. Under the restoring force of the first spring rod 36 and the second spring rod 38 supported by the second fixing seat 39, the first moving rod 35 and the second moving rod 37 automatically reset and drive the semi-circular ends to rotate in the opposite direction, and then lock into the limiting seat again, thereby completing the quick locking. The process does not require tools and greatly facilitates on-site maintenance.
