Description

Technical Field

[0001] This utility model belongs to the field of manhole cover technology, specifically relating to a non-load-bearing manhole cover structure for gas stations. Background Technology

[0002] Oil tanks are containers for storing crude oil or other petroleum products, typically installed underground at gas stations for convenient retrieval and storage. To facilitate handling of the crude oil or other petroleum products within the tanks, manholes are often installed above them. The internal space is used for installing equipment such as level gauges, oil pumps, pipeline valves, inlet and outlet pipes, and other pipelines. The inlet of the manhole is equipped with a cover for protection, theft prevention, and waterproofing. However, existing manhole covers are mostly made of exposed rubber, which is susceptible to aging or thermal expansion and contraction due to environmental factors, leading to reduced sealing and poor waterproofing. Furthermore, the sealing performance of manhole covers is usually only checked for leaks during use, further diminishing their effectiveness. Utility Model Content

[0003] (1) Technical problems to be solved

[0007] Optionally, two handles are installed on the top surface of the manhole cover.

[0008] Optionally, a fixing lock is installed through the outer surface of the manhole cover, and a baffle is fixedly connected to the inner wall of the mounting base.

[0009] Optionally, a sealing strip is fixedly connected to the outer surface of the top of the mounting base, and the sealing strip is in contact with the inside of the manhole cover.

[0010] Optionally, the sealing assembly includes: a pneumatic cylinder, a threaded rod, a threaded hole, a pneumatic tube, a rubber strip, an air pipe, a sealing channel, and a piston; the top surface of the manhole cover is through-installed with a pneumatic cylinder, and the outer surface of the pneumatic cylinder is provided with a threaded hole.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention involves installing a mounting base into a manhole, then placing the manhole cover into the mounting base, grasping the handle, and rotating the threaded rod. The threaded rod rotates and descends within the threaded hole, pushing a piston down within a pneumatic cylinder. The descending piston pushes air from the pneumatic cylinder through an air pipe into a pneumatic tube. The increased air volume in the pneumatic tube pushes a rubber strip to expand and enter the sealing channel. The expanded rubber strip presses against the inside of the sealing channel to create a seal. When the manhole cover ages or contracts due to thermal expansion and contraction, the air pressure in the pneumatic tube pushes the rubber strip to expand automatically, allowing it to fit tightly against the sealing channel and prevent air leakage. This increases the manhole cover's sealing and waterproof properties, ensuring its safety. A pressure gauge can be used to check the air pressure values ​​in the pneumatic cylinder and pneumatic tube. When the air pressure decreases or disappears, it indicates an air leak. At this time, the rubber strip is in an uninflated state, reducing its sealing performance. This allows for a direct visual inspection of whether the sealing performance has decreased, ensuring the effectiveness of the system. Attached Figure Description

[0022] This specific embodiment is a non-load-bearing manhole cover structure for gas stations, and its structural diagram is shown below. Figures 1-5 As shown, the manhole cover includes: a manhole cover 1, a mounting base 3, and a sealing assembly. The manhole cover 1 is positioned above the mounting base 3, and the sealing assembly is installed through the interior of the manhole cover 1. The sealing assembly includes: a pneumatic cylinder 6, a threaded rod 7, a threaded hole 9, a pneumatic pipe 11, a rubber strip 12, an air pipe 14, a sealing channel 15, and a piston 17. The pneumatic cylinder 6 is installed through the top surface of the manhole cover 1, and a threaded hole 9 is provided on the outer surface of the pneumatic cylinder 6. A threaded rod 7 is threadedly connected inside the threaded hole 9, and the piston 17 is rotatably connected to the bottom end of the threaded rod 7. The piston 17 is slidably installed inside the pneumatic cylinder 6. The bottom surface of the well cover 1 is fixedly connected to the pneumatic pipe 11, and the pneumatic cylinder 6 and the pneumatic pipe 11 are installed through the air pipe 14. The outer surface of the mounting base 3 is provided with a sealing channel 15. The outer surface of the pneumatic pipe 11 is installed through the rubber strip 12. The bottom surface of the pneumatic cylinder 6 is installed through the connecting pipe 13, and the top end of the connecting pipe 13 is installed through the inside of the pneumatic cylinder 6. The top end of the connecting pipe 13 is installed with a pressure gauge 4, and the top end of the threaded rod 7 is rotatably installed with a handle 8.

[0023] Specifically, by installing the mounting base 3 into the manhole, then holding the manhole cover 1 and placing it into the mounting base 3, grasping the handle 8 and rotating the threaded rod 7, the threaded rod 7 rotates and descends in the threaded hole 9, pushing the piston 17 down in the pneumatic cylinder 6. The descent of the piston 17 pushes the air in the pneumatic cylinder 6 into the pneumatic pipe 11 through the air pipe 14. The increased air in the pneumatic pipe 11 pushes the rubber strip 12 to expand and enter the sealing channel 15. The expanded rubber strip 12 presses against the inside of the sealing channel 15 to seal. When the manhole cover 1 ages or expands and contracts due to heat, the air pressure in the pneumatic pipe 11 pushes the rubber strip 12 to expand, allowing the rubber strip 12 to automatically expand and fit tightly against the sealing channel 15 to prevent air leakage, increasing the sealing and waterproof performance of the manhole cover 1 and ensuring its safety. The air pressure value in the pneumatic cylinder 6 and the pneumatic pipe 11 can be viewed through the air pressure gauge 4. When the air pressure value decreases or disappears, it indicates air leakage. At this time, the rubber strip 12 is in an uninflated state, and the sealing performance is reduced. This allows for a direct inspection of whether the sealing performance of the manhole cover 1 has decreased, ensuring its effectiveness.

[0024] Furthermore, two handles 5 are installed on the top surface of the manhole cover 1.

[0025] Specifically, the manhole cover 1 can be easily installed or removed by using handle 5.

[0026] Furthermore, a fixing lock 2 is installed through the outer surface of the manhole cover 1, and a baffle 16 is fixedly connected to the inner wall of the mounting base 3.

[0027] Specifically, the manhole cover 1 is locked by the fixing lock 2 in conjunction with the stop bar 16 to prevent the manhole cover 1 from being lost.

[0028] Furthermore, a sealing strip 10 is fixedly connected to the outer surface of the top of the mounting base 3, and the sealing strip 10 is in contact with the inside of the manhole cover 1.

[0029] Specifically, the sealing strip 10 is brought into contact with the manhole cover 1 to increase the sealing effect of the manhole cover 1.

[0030] This utility model discloses a non-load-bearing manhole cover structure for gas stations. The installation base 3 is installed into the manhole. Then, the manhole cover 1 is placed into the installation base 3, and the handle 8 is grasped to rotate the threaded rod 7. The threaded rod 7 rotates and descends within the threaded hole 9, pushing the piston 17 down within the pneumatic cylinder 6. The descending piston 17 pushes air from the pneumatic cylinder 6 through the air pipe 14 into the pneumatic pipe 11. The increased air in the pneumatic pipe 11 pushes the rubber strip 12 to expand and enter the sealing channel 15. The expanded rubber strip 12 abuts against the inside of the sealing channel 15 to seal the manhole cover. When aging or thermal expansion and contraction occurs, the air pressure inside the air pressure pipe 11 pushes the rubber strip 12 to expand, allowing the rubber strip 12 to automatically expand and fit tightly against the sealing channel 15 to prevent air leakage, thereby increasing the sealing and waterproof performance of the manhole cover 1 and ensuring its safety in use. The air pressure value inside the air pressure cylinder 6 and the air pressure pipe 11 can be viewed through the air pressure gauge 4. When the air pressure value decreases or disappears, it indicates air leakage. At this time, the rubber strip 12 is in an uninflated state, resulting in reduced sealing performance. This allows for a direct visual inspection of whether the manhole cover 1 has reduced sealing performance, ensuring its effectiveness in use.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
