Technical Field

[0001] This utility model relates to the field of natural gas technology, and in particular to a natural gas pipeline valve well leakage monitoring device. Background Technology

[0002] Leakage monitoring devices are often installed in natural gas pipeline valve wells to monitor for air leaks inside the wells and detect natural gas leaks in a timely manner. For example, in the prior art, Chinese patent application number 202322007996.6 discloses a natural gas leakage monitoring device with multiple installation methods.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Example 1

[0038] Reference Figure 1-4 A natural gas pipeline valve well leakage monitoring device includes a natural gas pipeline valve well leakage monitor 1 and a mounting plate 2. The natural gas pipeline valve well leakage monitoring device further includes:

[0039] Telescopic cylinder 3 is bolted to the surface of mounting plate 2;

[0040] Cantilever 4 is slidably connected to the inside of telescopic cylinder 3;

[0041] Support plate 5 is bolted to the right end of cantilever 4;

[0042] Support base 6 is bolted to the top of support plate 5;

[0043] The lifting assembly includes a winding wheel 11, a connecting belt 12, and a chuck 13. The inside of the winding wheel 11 is wound around the top of the connecting belt 12, the bottom of the connecting belt 12 is bolted to the top of the chuck 13, and the bottom of the chuck 13 is engaged with the top of the natural gas pipeline valve well leak monitor 1.

[0044] The power mechanism is connected to the winding reel 11. Through the setting of the telescopic cylinder 3 and the cantilever 4, the position of the natural gas pipeline valve well leakage monitor 1 can be adjusted. The height of the natural gas pipeline valve well leakage monitor 1 can be adjusted by rotating the winding reel 11, so that the natural gas pipeline valve well leakage monitor 1 can monitor at different heights, and at the same time, it is convenient for workers to maintain the natural gas pipeline valve well leakage monitor 1.

[0045] To facilitate the rotation of the take-up reel 11, such as Figure 2 As shown, the power mechanism includes a geared motor 7, a main bevel gear 8, a secondary bevel gear 9, and a rotating shaft 10. The output end of the geared motor 7 is keyed to the shaft center of the main bevel gear 8. The teeth of the main bevel gear 8 mesh with the teeth of the secondary bevel gear 9. The shaft center of the secondary bevel gear 9 is keyed to the surface of the rotating shaft 10. The middle end of the surface of the rotating shaft 10 is keyed to the shaft center of the take-up reel 11. When the power supply to the geared motor 7 is turned on, the power supply can be either an external power supply or an internal power supply. The geared motor 7 is controlled by a controller. The geared motor 7 can drive the main bevel gear 8 to rotate, the main bevel gear 8 can drive the secondary bevel gear 9 to rotate, the secondary bevel gear 9 can drive the rotating shaft 10 to rotate, and the rotating shaft 10 can drive the take-up reel 11 to rotate.

[0046] To protect structures such as the winding reel 11, such as Figure 3As shown, the transmission box 14 is bolted to the inner side of the support base 6. The rotating shaft 10 and the winding wheel 11 are both located inside the transmission box 14. The transmission box 14 is fixed by the support base 6 to ensure the stability of the transmission box 14. The rotating shaft 10 is rotatably set with the transmission box 14 through the bearing to ensure the smoothness of the rotation of the rotating shaft 10.

[0047] To secure the geared motor 7 and the rotating shaft 10, such as Figure 2 As shown, the surface of the geared motor 7 is bolted to the inside of the transmission box 14, and both ends of the rotating shaft 10 are rotatably connected to the inside of the transmission box 14. The geared motor 7 is fixed by the transmission box 14 to ensure the stability of the geared motor 7. The rotating shaft 10 is rotatably set with the transmission box 14 through bearings.

[0048] In order to boot disk 13, such as Figure 1 As shown, a support rod 15 is bolted to the right side of the top of the chuck 13. The surface of the support rod 15 is slidably connected to the sliding hole of the support plate 5. The chuck 13 is guided by the support plate 5 through the support rod 15, which facilitates the up and down movement of the chuck 13 and helps to ensure the stability of the chuck 13.

[0049] To stabilize the telescopic cylinder 3, such as Figure 4 As shown, a triangular plate is bolted to the bottom of the telescopic cylinder 3. The triangular plate is bolted to the mounting plate 2. The triangular plate can support and stabilize the telescopic cylinder 3, ensuring the stability of the telescopic cylinder 3 and facilitating the movement and adjustment of the cantilever 4.

[0050] To ensure the stability of cantilever 4, such as Figure 4 As shown, a tensioning bolt is threaded into the screw hole at the top of the telescopic cylinder 3. The tensioning bolt abuts against the cantilever 4. The tensioning bolt can fix the telescopic cylinder 3 and the cantilever 4, ensuring the stability of the cantilever 4 and facilitating its movement.

[0051] Example 2

[0052] The difference between this embodiment and Embodiment 1 is that the geared motor 7, main bevel gear 8, and secondary bevel gear 9 are replaced by an electric push cylinder, a rack connected to the output end of the electric push cylinder, and a pinion meshing with the rack teeth. The electric push cylinder can drive the pinion to rotate through the rack, but the stability of this transmission structure is poor. Therefore, this application preferably uses a geared motor 7, main bevel gear 8, and secondary bevel gear 9.

[0053] It should be noted that the specific model of geared motor 7 used should be selected by those skilled in the art, and the geared motor 7 mentioned above is all existing technology, so this solution will not elaborate on it.

[0054] The natural gas pipeline valve well leakage monitor 1 adopts existing technology and can use the leakage monitoring structure of the patent with application number 202010217419.8.

[0055] The working principle of this utility model is as follows: The mounting plate 2 is installed at a suitable position in the natural gas pipeline valve well. The natural gas pipeline valve well leakage monitor 1 can be a battery-powered model. The telescopic cylinder 3 and the cantilever 4 can be telescopic to adjust the position of the support plate 5. The power supply of the reduction motor 7 is connected. The power supply can be an external power supply or an internal power supply. The reduction motor 7 is controlled by a controller. The reduction motor 7 can drive the main bevel gear 8 to rotate. The main bevel gear 8 can drive the secondary bevel gear 9 to rotate. The secondary bevel gear 9 can drive the rotating shaft 10 to rotate. The rotating shaft 10 can drive the winding wheel 11 to rotate. The winding wheel 11 can release the connecting belt 12 downwards and can also wind the connecting belt 12 upwards. The connecting belt 12 can drive the chuck 13 to move. When the chuck 13 moves upwards, the convex structure on the top of the chuck 13 can engage with the groove at the bottom of the support plate 5. The chuck 13 can drive the natural gas pipeline valve well leakage monitor 1 to rise and fall.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
