[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1:

[0054] See also Figure 1-Figure 4 A petrochemical flame arrester with automatic detection and repair functions includes a housing 1, a sealing connection mechanism 2, a positioning mechanism 4, a detection mechanism 3, and a repair mechanism 5. The number of the housings 1 is two, and a cavity is formed in the middle of the two housings 1 after they are connected. A fire arrester unit 101 is provided in the cavity. Figure 2The sealing connection mechanism 2 includes a connection ring 201 disposed on one side of the housing 1, with a sealing gasket 202 disposed between the two connection rings 201. A positioning mechanism 4 is disposed on the outside of the housing 1 and is used to fix the position of the connection ring 201. A detection mechanism 3 is disposed on top of the positioning mechanism 4 and is used to detect gas leaks. Repair mechanisms 5 are provided on both sides of the positioning mechanism 4 and are used to prevent gas leaks.

[0055] It should be noted that a flame arrester is provided with a fire arrester unit 101 made of a small perforated plate or a mesh made of metal wire. These materials can effectively prevent the direct spread of flames. The connecting ring 201 is sleeved on the outside of the outer shell 1. When the two outer shells 1 need to be fixed, the position of the outer shell 1 is fixed by fixing the connecting ring 201. The sealing gasket 202 is made of rubber material. When the rubber material is squeezed, it will deform, thereby sealing the connection between the two outer shells 1.

[0056] For details, see Figure 1 and Figure 2 The positioning mechanism 4 includes a clamp 401, a connecting ear 404, a bolt 402, and a nut 403. A mounting groove is defined on the side of the clamp 401 near the connecting ring 201, with the connecting ring 201 located within the mounting groove. The connecting ear 404 is fixedly connected to the end of the clamp 401. The bolt 402 is inserted into the middle of the connecting ear 404. The nut 403 is threaded onto one end of the bolt 402.

[0057] For details, see Figure 2 The horizontal longitudinal section of the mounting groove in the clamp 401 is set to be an isosceles trapezoid, and the mounting groove is used to fix the position of the connecting ring 201.

[0058] It should be noted that through holes are opened on multiple connecting ears 404, and bolts 402 are provided to be inserted and connected inside the through holes. When the position between the two connecting rings 201 needs to be fixed, the side with the installation groove on the two clamps 401 is first fitted with the connecting ring 201, and then the bolts 402 are inserted into the through holes on the connecting ears 404 on the same side of the two clamps 401, and then the nuts 403 are threaded onto the bolts 402, and the two connecting ears 404 are squeezed and fixed by the screw heads of the nuts 403 and the bolts 402, and the position of the clamps 401 is fixed by the connecting ears 404 in the fixed position, so that the connecting ring 201 is fixed by the clamps 401 in the fixed position.

[0059] For details, see Figure 1 and Figure 2The detection mechanism 3 includes a pole 301, a mounting plate 302, and a gas alarm 303. The pole 301 is fixedly connected to the top of one of the clamps 401; the mounting plate 302 is fixedly connected to one side of the pole 301; and the gas alarm 303 is fixedly connected to one side of the mounting plate 302. The gas alarm 303 is used to detect gas leaks.

[0060] For details, see Figure 1 、 Figure 4 、 Figure 5 and Figure 6 The repair mechanism 5 includes a mounting frame 501, an electric push rod 502, and an extrusion block 503. The mounting frame 501 is fixedly connected to one side of the clamp 401; the electric push rod 502 is fixedly connected to one side of the mounting frame 501; the extrusion block 503 is fixedly connected to the output end of the electric push rod 502. The connection between the extrusion block 503 and the connecting ear 404 is provided with a limiting component 6 for limiting the shaking of the connecting ear 404. The connection between the extrusion block 503 and the mounting frame 501 is provided with a control component 7 for controlling the movement distance of the extrusion block 503.

[0061] It should be noted that the electric push rod 502 is an existing electric push rod with a self-locking function, that is, when the motor stops working, the lead screw or screw system can lock the rod body to prevent it from being recovered due to external force; the extrusion block 503 is set to an inclined surface on the side close to the connecting ear 404. When the connecting bolt 402 and the nut 403 between the two connecting ears 404 are loose, the electric push rod 502 is opened, and the extrusion block 503 is driven by the electric push rod 502 to extrude one side of the connecting ear 404, so that on one side of the clamp 401, one of the connecting ears 404 moves toward the side of the other connecting ear 404, thereby squeezing the two clamps 401 toward the opposite side, and re-extruding and fixing the two connecting rings 201 through the clamp 401 to prevent gas leakage.

[0062] For details, see Figure 5 The limiting assembly 6 includes a limiting groove 601 and a limiting block 602. The limiting groove 601 is formed on one side of the connecting ear 404; the limiting block 602 is inserted and connected to the interior of the limiting groove 601. The side of the extrusion block 503 near the connecting ear 404 has an insertion hole, and the limiting block 602 is inserted and connected to the interior of the insertion hole. The connection between the limiting block 602 and the extrusion block 503 is provided with a fixing member 8 for fixing the position of the limiting block 602.

[0063] It should be noted that the limiting block 602 is fixed to the extrusion block 503 through the fixing part 8, and the extrusion block 503 is perpendicular to the position of one of the connecting ears 404 through the electric push rod 502 and the mounting frame 501. The limiting block 602 is inserted and connected to the inside of the other connecting ear 404, so that the limiting block 602 is perpendicular to the other connecting ear 404, avoiding the situation where the two connecting ears 404 are misaligned due to shaking when the bolt 402 and the nut 403 are loose.

[0064] For details, see Figure 4 The control assembly 7 includes a travel switch 701, a pressing block 702, and a movable hole 703. The travel switch 701 is fixedly connected to the bottom of the mounting frame 501; the pressing block 702 is fixedly connected to the bottom of the extrusion block 503; the movable hole 703 is opened at the bottom of the mounting frame 501, and the pressing block 702 is inserted into the interior of the movable hole 703.

[0065] It should be noted that the travel switch 701 is electrically connected to the control end of the electric push rod 502. When in use, when the pressing block 702 moves to fit with the travel switch 701, the travel switch 701 will close the electric push rod 502.

[0066] Example 2:

[0067] The fixing member 8 is applied to the flame arrester in the first embodiment.

[0068] For details, see Figure 5 The fixing member 8 includes a connecting block 802, a slot 803, a clamping block 804, and a movable portion. A connecting slot 801 is provided on one side of the extrusion block 503, and the connecting block 802 is inserted and connected to the interior of the connecting slot 801; the clamping slot 803 is provided at the bottom of the connecting block 802; the clamping block 804 is inserted and connected to the interior of the clamping slot 803, and the clamping block 804 is used to restrict the connection block 802 from moving out of the connecting slot 801; the movable portion is provided at the bottom of the clamping block 804, and is used to move the position of the clamping block 804.

[0069] It should be noted that the inserted hole and the connecting groove 801 are connected to each other. When the position of the limiting block 602 needs to be fixed, the limiting block 602 is inserted into the inside of the inserted hole from the connecting groove 801, and the limiting block 602 is allowed to pass out from the inside of the connecting groove 801. The horizontal longitudinal cross-sectional area of ​​the connecting block 802 is larger than the horizontal longitudinal cross-sectional area of ​​the inserted hole, so that the connecting block 802 cannot pass into the inside of the inserted hole. When the connecting block 802 moves to one side of the inserted hole, the connecting block 802 will be restricted by the connecting groove 801, so that the connecting block 802 02 cannot continue to move toward the side of the limiting block 602, and the limiting block 602 is restricted by the connecting block 802 that limits the moving distance; the set card block 804 is adapted to the opened card slot 803, and when the top of the card block 804 is inserted into the interior of the card slot 803, the bottom of the card block 804 is still inserted and connected to the inner wall of the bottom end of the connecting slot 801, thereby restricting the connecting block 802 by the card block 804 that limits the moving direction, making it impossible for the connecting block 802 to move. When the position of the connecting block 802 needs to be moved, the card block 804 needs to be moved out of the card slot 803.

[0070] For details, see Figure 5 The moving part includes a driving block 806, a penetration block 805, a pushing block 809, and a spring 808. The driving block 806 is fixedly connected to the bottom end of the clamping block 804; the penetration block 805 is fixedly connected to one side of the driving block 806; the pushing block 809 is fixedly connected to one side of the penetration block 805 and is used to drive the clamping block 804 to move; and the spring 808 is provided at the bottom of the driving block 806 and is used to push the driving block 806.

[0071] Specifically, a cavity 807 is opened in the middle of the extrusion block 503, the driving block 806 and the spring 808 are both inserted and connected inside the cavity 807, the clamping block 804 is inserted and connected to the inner wall at the top of the cavity 807, and a through hole is opened on the inner wall on one side of the cavity 807, and the through hole block 805 is inserted and connected inside the through hole.

[0072] It should be noted that a hole is provided on the inner wall at the top of the cavity 807, which is adapted to the card block 804, so that the card block 804 can pass through the hole to penetrate into the interior of the cavity 807 and the connecting groove 801; the spring 808 is located at the bottom of the driving block 806, and is used to push the driving block 806 to one side of the card block 804, so as to prevent the card block 804 from moving downward when the position of the connecting block 802 needs to be fixed; the outlet block 805 is provided and the outlet hole is provided to connect the driving block 806 located inside the cavity 807 and the pushing block 809 located outside the cavity 807. When in use, the driving block 806 located inside the cavity 807 is driven to move by the pushing block 809.

[0073] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
