Description

Technical Field

[0001] The invention belongs to the technical field of monitoring devices, and in particular relates to an intelligent monitoring device for a long-distance pipeline. Background Art

[0002] As a kind of intelligent monitoring device for long-distance pipelines, test piles are usually used to measure key parameters such as cathodic protection potential, current, ground resistance, etc. at the main distribution points of the cathodic protection system. By detecting the pressure changes in the pipeline and uploading the measured data to the remote terminal, the detection accuracy of pipeline leakage can be improved. When a pipeline leaks, the pressure changes are captured and reported in time, making it easier for maintenance personnel to take countermeasures quickly.

[0003] Some test piles in the prior art usually have the defect that the protective cover is not easy to open. If the protective cover is not easy to open, obstacles will be encountered when reading or calibrating the monitoring data, resulting in delayed data acquisition, which may affect the timely judgment and processing of the pipeline operation status. At the same time, some test piles whose height is not easy to adjust may find it difficult to cover all areas that need to be monitored in complex terrain or areas with large changes in pipeline depth, thereby resulting in monitoring blind spots. These blind spots may become breeding grounds for safety hazards, thereby posing a threat to the safe operation of the pipeline. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides an intelligent monitoring device for a long-distance pipeline, comprising:

[0030] The protection mechanism 100 includes a protection shell 101, and a protection door 102 is hingedly connected to one side of the outer surface of the protection shell 101;

[0031] Among them, a data acquisition module and a data transmission module are provided in the protective shell 101. The data acquisition module is responsible for real-time collection of key parameters such as pressure, temperature, flow rate, etc. at the oil and gas wellhead or along the pipeline. The data acquisition module converts physical quantities into processable electrical signals through high-precision sensors and conversion circuits. The data transmission module transmits the collected data to a remote monitoring center through methods such as GPRS and NB-IoT to achieve remote data transmission and real-time monitoring. The protective door 102 is used to protect the data acquisition module and the data transmission module.

[0032] The fixing mechanism 200 includes a fixing box 201 fixedly mounted on one side surface of the protective door 102, a driving rod 202 is rotatably connected to one side of the inner surface of the fixing box 201, a worm 203 is fixedly connected to the other end of the driving rod 202, and the other end of the worm 203 is fixedly mounted on one side surface of the inner wall of the fixing box 201 through a bearing;

[0033] The fixing box 201 is used to stably support the components in the fixing mechanism 200 , and the rotating driving rod 202 can drive the worm 203 to rotate.

[0034] The lifting mechanism 300 includes a movable sleeve 301 fixedly connected to the bottom of the outer surface of the protective shell 101 , and a fixed sleeve 302 slidably connected to the inner surface of the movable sleeve 301 .

[0035] The fixed sleeve 302 is used to limit the movable sleeve 301 so as to prevent the movable sleeve 301 from shifting.

[0036] Specifically, a driven rod 204 is fixedly mounted on one side surface of the inner wall of the fixed box 201 via a bearing, and a worm wheel 205 and a gear 206 are fixedly mounted on the surface of the driven rod 204 via a bearing.

[0037] The spiral pattern of the worm 203 meshes with the worm gear 205 . When the worm 203 rotates, it can drive the worm gear 205 to rotate. The worm gear 205 drives the driven rod 204 to rotate, and the driven rod 204 drives the gear 206 to rotate synchronously.

[0038] Furthermore, the fixing mechanism 200 also includes a fixing frame 207 fixedly installed on one side of the inner wall of the fixing box 201, the inner surface of the fixing frame 207 is slidably connected with a toothed bar 208, and one side of the outer surface of the protective shell 101 is fixedly connected with an ear piece 209.

[0039] The teeth of the gear 206 mesh with the teeth of the toothed bar 208 . When the gear 206 rotates, it can drive the toothed bar 208 to perform linear motion in the fixed frame 207 .

[0040] When in use, rotating the driving rod 202 drives the worm 203 to rotate, so that the worm 203 drives the worm wheel 205 to rotate, and the worm wheel 205 drives the driven rod 204 to rotate, and then the driven rod 204 drives the gear 206 to rotate synchronously, and the gear 206 drives the toothed bar 208 to move linearly, so that the toothed bar 208 moves into the ear piece 209, thereby limiting the protective door 102, and the protective door 102 can be released by rotating the driving rod 202 in the opposite direction.

[0041] In summary, when the test pile needs to be inspected, maintained or data read, the easy-to-open protective door 102 can be opened quickly to reduce the opening time and improve maintenance efficiency. Through the special lock, the protective door 102 can fit tightly to the test pile when it is closed, thereby effectively preventing external moisture, dust, small animals, etc. from entering the interior of the test pile to protect the internal equipment from damage.

[0042] Example 2

[0043] Reference Figure 1 , Figure 4 and Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a lifting mechanism 300 that can facilitate maintenance personnel to flexibly adjust the height of the test pile.

[0044] Specifically, one end of the fixed sleeve 302 is fixedly connected to the base 303 , and one side of the inner surface of the movable sleeve 301 is rotatably connected to the rotating rod 304 .

[0045] The base 303 is fixed to the ground by bolts, so that the base 303 can firmly fix the fixing sleeve 302 .

[0046] Furthermore, a ratchet 305 is rotatably connected to the surface of the rotating rod 304 , and a fixing block 306 is fixedly connected to one side of the outer surface of the movable sleeve 301 .

[0047] The rotating rod 304 can drive the ratchet wheel 305 to rotate.

[0048] Preferably, a limiting sleeve 307 is fixedly mounted on one side of the outer surface of the movable sleeve 301 , and a ratchet 308 is slidably connected to the inner surface of the limiting sleeve 307 .

[0049] The movable sleeve 301 is used to support the fixed block 306 and the limiting sleeve 307 , and one side surface of the fixed block 306 and one end of the pawl 308 are fixedly connected with the same spring.

[0050] It should be noted that one end of the rotating rod 304 is fixedly connected to the first bevel gear 309 , and the inner wall surface of the movable sleeve 301 is fixedly connected to the supporting plate 310 .

[0051] The rotating rod 304 can also drive the first bevel gear 309 to rotate synchronously.

[0052] Furthermore, the inner surface of the support plate 310 is rotatably connected to the second bevel gear 311 , and the teeth of the first bevel gear 309 mesh with the teeth of the second bevel gear 311 .

[0053] When the first bevel gear 309 rotates, the second bevel gear 311 can be driven to rotate.

[0054] Preferably, the lifting mechanism 300 further includes a screw rod 312 fixedly connected to one end of the second bevel gear 311 , the surface of the screw rod 312 is threadedly connected with an internal thread block 313 , and the internal thread block 313 is fixedly connected to the inner surface of the fixing sleeve 302 .

[0055] Among them, when the second bevel gear 311 rotates, it can drive the screw rod 312 to rotate synchronously. Through the fixed sleeve 302 limiting the internal thread block 313, the screw rod 312 drives the support plate 310 to move linearly while rotating, and then the support plate 310 drives the movable sleeve 301 to move synchronously.

[0056] When in use, rotating the rotating rod 304 drives the ratchet 305 and the first bevel gear 309 to rotate synchronously, so that the first bevel gear 309 drives the second bevel gear 311 to rotate, and the fixed sleeve 302 limits the internal thread block 313, so that the screw rod 312 drives the support plate 310 to move in a straight line while rotating, and the support plate 310 drives the movable sleeve 301 to move synchronously, so that the movable sleeve 301 drives the protective shell 101 and the data acquisition module and data transmission module inside it to adjust the height. When the rotating rod 304 stops rotating, the limit sleeve 307 limits the pawl 308, so that the pawl 308 limits the ratchet 305, thereby preventing the rotating rod 304 from rotating in the opposite direction due to accidental touch.

[0057] In summary, by flexibly adjusting the height of the test pile, the distance between the data acquisition module and the long-distance pipeline can be ensured to remain at the optimal state, which can not only improve the accuracy and reliability of the measurement data, but also reduce the measurement errors caused by factors such as uneven terrain and installation errors, so as to ensure that the data truly reflects the actual condition of the pipeline.
