Description

Technical Field

[0001] This utility model relates to the field of safety monitoring technology, and in particular to an oil and gas safety monitoring device. Background Technology

[0002] Natural gas is found in porous underground rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogenic gas, with small amounts also found in coal seams. It is a high-quality fuel and chemical feedstock. Natural gas is primarily used as fuel, but it can also be used to manufacture carbon black, chemicals, and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of a mixture of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.

[0003] In the prior art, such as the oil and gas safety monitoring device described in Chinese patent CN 216408592 U, there is a monitoring device body, a pipeline, and a signal transmitting mechanism. The monitoring device body is fixedly mounted on the surface of the pipeline. An ARM microcontroller is fixedly mounted on one side inside the monitoring device body, and a battery is located at the lower end of the ARM microcontroller. The signal transmitting mechanism is fixedly mounted at the center inside the monitoring device body. Due to the high pressure in the oil and gas pipeline, the pressure difference pushes the sealing cover plate to press against the sealing ring to maintain the seal. When the pipeline ruptures and leaks, the pressure loss causes the sliding plate to squeeze the pressure sensor under the action of a spring. At this time, the ARM microcontroller controls the servo motor to start, which rotates the lead screw and acts on the nut at the bottom of the square hollow slide rod, causing the square hollow slide rod to slide out of the square sliding sleeve. This causes the wireless signal transceiver to extend and transmit a signal to the terminal to alarm and notify maintenance personnel to carry out maintenance. However, this patent still has the following problems.

[0004] In the aforementioned patent, although a wireless transceiver is included, which can transmit a signal to the terminal to alert maintenance personnel when the transceiver leaves the device, external dust, sand, and other debris may enter the gap between the square hollow slide rod and the square sliding sleeve when the transceiver leaves the device, hindering its sliding and potentially damaging the internal electronic components, thus reducing the reliability and lifespan of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when the wireless transceiver leaves the device, external dust, sand and other debris may enter the gap between the square hollow slide rod and the square sliding sleeve, and to propose an oil and gas safety monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil and gas safety monitoring device, comprising a pipeline, an opening penetrating through the inner wall of the pipeline, a device body disposed inside the opening, a fixing plate fixedly installed on the inner wall of the device body, an electric telescopic rod fixedly installed on the top of the fixing plate, a wireless signal transceiver fixedly installed at the telescopic end of the electric telescopic rod, a placement opening penetrating through the top surface of the device body, a top plate disposed on the top of the wireless signal transceiver, a placement groove disposed on the top of the device body, a slot disposed on the bottom of the top plate, two insert plates symmetrically arranged inside the slot, a dustproof plate fixedly installed on the bottom of the insert plates, a slot on the outer wall of the insert plates, a limit groove disposed on both sides inside the slot, two pull grooves symmetrically disposed on the bottom of the top plate, two second springs fixedly installed on the inner wall of the limit grooves, a locking block fixedly installed on one end of each of the two second springs, a connecting rod fixedly installed on the outer wall of the locking block, and one end of the connecting rod entering the pull groove and fixedly installed with a pull plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the wireless transceiver leaves the device body, the top plate rises, which in turn drives the dustproof plate to rise.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, this utility model provides an oil and gas safety monitoring device, including a pipeline 1. An opening 5 is formed through the inner wall of the pipeline 1. A device body 3 is disposed inside the opening 5. A fixing plate 23 is fixedly installed on the inner wall of the device body 3. An electric telescopic rod 24 is fixedly installed on the top of the fixing plate 23. A wireless signal transceiver 26 is fixedly installed at the telescopic end of the electric telescopic rod 24. A placement opening 25 is formed through the top surface of the device body 3. A top plate 4 is provided on the top of the wireless signal transceiver 26. A placement groove 27 is formed on the top of the device body 3. The bottom of the plate 4 has a slot 28, and two insert plates 29 are symmetrically arranged inside the slot 28. A dustproof plate 30 is fixedly installed at the bottom of the insert plate 29. A slot 31 is opened on the outer wall of the insert plate 29. Limiting grooves 32 are opened on both sides inside the slot 28. The bottom of the top plate 4 has two pull grooves 33 symmetrically arranged. Two second springs 34 are fixedly installed on the inner wall of the limiting groove 32. A locking block 35 is fixedly installed at one end of the two second springs 34. A connecting rod 36 is fixedly installed on the outer wall of the locking block 35. One end of the connecting rod 36 enters the pull groove 33 and is fixedly installed with a pull plate 37.

[0024] The effect achieved by the entire embodiment 1 is as follows: when the wireless transceiver 26 leaves the device body 3, the top plate 4 rises, which in turn drives the dustproof plate 30 to rise. At this time, the dustproof plate 30 can prevent external dust from entering the device body 3. When it is necessary to replace or clean the dustproof plate 30, the operator starts the electric telescopic rod 24, and the dustproof plate 30 leaves the placement slot 27. At this time, the operator pulls the pull plate 37, and the locking block 35 leaves the slot 31. At this time, the operator can pull out the insert plate 29 to clean or replace the dustproof plate 30. Then, the insert plate 29 is inserted into the slot 28. The insert plate 29 contacts the inclined surface of the locking block 35. The locking block 35 is squeezed into the limiting groove 32, and the second spring 34 is compressed. When the slot 31 moves to the side of the locking block 35, the elastic force of the second spring 34 pushes the locking block 35 into the slot 31, and the installation is completed.

[0025] Example 2, as Figures 1-4 As shown, further, two grooves 6 are provided on the outer wall of the pipe 1, and a connecting groove 7 is provided on the inner wall of the grooves 6.

[0026] Furthermore, a connecting plate 2 is fixedly installed on the outer wall of the device body 3. Two fixing grooves 8 are opened inside the connecting plate 2. A through opening 9 is opened through the bottom surface of the inner wall of the fixing groove 8. A threaded hole 10 is opened through the inner wall of the fixing groove 8. A threaded rod 11 is threadedly connected inside the threaded hole 10. A handle 12 is fixedly installed at one end of the threaded rod 11. A movable block 13 is movably connected to the end of the threaded rod 11 away from the handle 12. An L-shaped block 14 is fixedly installed at the bottom of the movable block 13.

[0027] Furthermore, a sealing ring 16 is fixedly installed at the bottom of the connecting plate 2, and a sealing groove 15 is opened on the outer wall of the pipe 1 to improve the sealing performance and prevent air leakage.

[0028] Furthermore, a storage slot 17 is provided at the bottom of the device body 3. A lifting plate 18 is slidably installed inside the storage slot 17. A lifting rod 19 is fixedly installed on the top of the lifting plate 18. The top of the lifting rod 19 enters the device body 3 and a touch plate 20 is fixedly installed thereon. Two first springs 21 are fixedly connected between the touch plate 20 and the bottom surface inside the device body 3. A pressure sensor 22 is fixedly installed on the bottom surface inside the device body 3.

[0029] Furthermore, the outer wall of the insert plate 29 fits against the inner wall of the slot 28, and the outer wall of the card block 35 fits against the inner wall of the card groove 31. When the card block 35 enters the card groove 31, the insert plate 29 can be fixed in place.

[0030] Furthermore, the outer wall of the movable block 13 is in contact with the inner wall of the fixed groove 8 to prevent the movable block 13 from rotating when the threaded rod 11 rotates.

[0031] The overall effect of Embodiment 2 is that when disassembling the device body 3, the operator rotates the handle 12, the threaded rod 11 rotates, driving the moving block 13 to move, and the L-shaped block 14 leaves the connecting groove 7. At this time, the operator can pull out the L-shaped block 14, and then pull the device body 3 out from the opening 5. During installation, the operator inserts the two L-shaped blocks 14 into the two sliding grooves 6 respectively, rotates the handle 12 in the opposite direction, and the L-shaped blocks 14 enter the connecting groove 7, thus completing the installation and improving the efficiency of installation and disassembly.

[0032] Working principle: During use, the pressure in pipe 1 is very high. Under the action of pressure difference, the lifting plate 18 is pushed into the storage tank 17, and the first spring 21 is stretched. When pipe 1 is ruptured and leakage occurs, the elastic force of the first spring 21 pushes the touch plate 20 to contact the pressure sensor 22. At this time, the telescopic end of the electric telescopic rod 24 is stretched, thereby driving the wireless signal transceiver 26 to leave the device body 3 and transmit a signal to the terminal to alarm and notify maintenance personnel to carry out maintenance. When the wireless transceiver 26 leaves the device body 3, the top plate 4 rises, which in turn raises the dustproof plate 30. At this time, the dustproof plate 30 can prevent external dust from entering the device body 3. When the dustproof plate 30 needs to be replaced or cleaned, the operator starts the electric telescopic rod 24, and the dustproof plate 30 leaves the placement slot 27. At this time, the operator pulls the pull plate 37, and the locking block 35 leaves the slot 31. At this time, the operator can pull out the insert plate 29 to clean or replace the dustproof plate 30. Then, the insert plate 29 is inserted into the slot 28. The insert plate 29 contacts the inclined surface of the locking block 35. The locking block 35 is squeezed into the limiting groove 32, and the second spring 34 is compressed. When the slot 31 moves next to the locking block 35, the elastic force of the second spring 34 pushes the locking block 35 into the slot 31, and the installation is completed. When disassembling the device body 3, the operator rotates the handle 12, causing the threaded rod 11 to rotate and move the moving block 13. The L-shaped block 14 then leaves the connecting groove 7, allowing the operator to pull out the L-shaped block 14 and remove the device body 3 from the opening 5. During installation, the operator inserts the two L-shaped blocks 14 into the two sliding grooves 6 respectively, and rotates the handle 12 in the opposite direction, causing the L-shaped blocks 14 to enter the connecting groove 7. This completes the installation and improves the efficiency of installation and disassembly.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
