[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A road utility tunnel sealing device includes a sealing block with a protective mechanism on its exterior. The protective mechanism includes protective grooves on both sides of the sealing block and multiple mounting grooves on one side of the inner wall of the protective grooves. A rotating rod 1 passes through the inner wall of the multiple mounting grooves. A miniature gas spring is mounted on the surface of the rotating rod 1. A rotating rod 2 is mounted on one end of the miniature gas spring. Protective covers are connected to both ends of the rotating rod 2. A rotating rod 3 is connected to one end of the protective cover. The rotating rod 3 is connected through the inner wall of the protective groove.

[0007] Furthermore, in order to better seal the road utility tunnel, a sealing mechanism is installed on the inner wall of the protective trench. The sealing mechanism includes an inflatable sealing balloon fixedly installed on the inner wall of the protective trench. The inner wall of the protective trench has a communicating inflation hole. The inner wall of the inflation hole is opposite to the position of the inflatable sealing balloon. A connecting hole is opened on the sealing block. The inner wall of the connecting hole is connected to the inner wall of the inflation hole. An inflation column is threadedly connected to the inner wall of the connecting hole. One end of the inflation column extends to the inner wall of the inflation hole.

[0008] Furthermore, in order to better control inflation and deflation, a three-way pipe is fixedly installed at the end of the inflation column away from the inflation hole, and control valves are installed at both ends of the three-way pipe.

[0009] Furthermore, in order to better filter the incoming gas, one end of the control valve is connected to a delivery pipe, one end of the delivery pipe is connected to a filter box, and an input pipe runs through one side of the filter box.

[0010] Furthermore, in order to facilitate the disassembly and maintenance of the filter screen and activated carbon screen, multiple filter slots are provided on one side of the filter box. Filter frames are installed on the inner walls of the multiple filter slots, and filter screens and activated carbon screens are installed on the inner walls of the filter frames respectively.

[0011] Furthermore, in order to better improve the tightness of the filter frame, multiple snap-fit ​​blocks are fixed on one side of the filter frame, and one end of the snap-fit ​​blocks snaps into one side of the filter box.

[0012] Furthermore, in order to better improve the sealing performance of the filter frame, a sealing gasket is inserted through the surface of the snap-fit ​​block, and the side of the sealing gasket contacts the side of the filter box.

[0013] Furthermore, in order to better improve the stability of the inflatable column, a limiting plate is fixedly provided on the surface of the inflatable column.

A protective cover 204 is connected to both ends of the rotating rod 203. A rotating rod 205 is connected to one end of the protective cover 204. The rotating rod 205 is connected through the inner wall of the protective groove.

[0031] A sealing mechanism 3 is installed on the inner wall of the protective groove. The sealing mechanism 3 includes an inflatable sealing balloon 301 fixedly installed on the inner wall of the protective groove. The inflatable sealing balloon 301 is made of rubber or other materials, so it will not be described in detail. The inner wall of the protective groove has a communicating inflation hole 302. The inner wall of the inflation hole 302 is opposite to the position of the inflatable sealing balloon 301. A connecting hole 303 is opened on the sealing block 1. The inner wall of the connecting hole 303 is connected to the inner wall of the inflation hole 302. An inflation column 304 is threadedly connected to the inner wall of the connecting hole 303. The inflation column 304 has a hollow structure and is used to inflate the inflatable sealing balloon 301. A sealing plate 17 is provided on the surface of the inflation column 304. A sealing gasket 18 is fixed below the sealing plate 17. The lower part of the sealing gasket 18 contacts the upper part of the sealing block 1. One end of the inflation column 304 extends to the inner wall of the inflation hole 302.

[0032] Example 2:

[0033] Please see Figures 1-6A road pipe gallery sealing device is provided with a three-way pipe 4 fixedly installed at the end of the air column 304 away from the air hole 302. The two ends of the three-way pipe 4 are respectively installed with control valves 5. One end of the control valve 5 is connected to a delivery pipe 6. One end of the delivery pipe 6 is connected to a filter box 7. The other end of the delivery pipe 6 is connected to a vacuum pump (not shown in the figure) in actual use. An input pipe 8 runs through one side of the filter box 7. One end of the input pipe 8 is connected to an air pump (not shown in the figure) in actual use. Two filter grooves are opened on one side of the filter box 7. Filter frames 9 are installed on the inner walls of the two filter grooves. Filter mesh plates 10 and activated carbon mesh plates 11 are respectively installed on the inner walls of the filter frames 9.

[0034] Four snap-fit ​​blocks 12 are fixed on one side of the filter frame 9. One end of the snap-fit ​​block 12 snaps into one side of the filter box 7. A sealing gasket 13 penetrates the surface of the snap-fit ​​block 12. The side of the sealing gasket 13 contacts the side of the filter box 7. A limiting plate 14 is fixed on the surface of the inflation column 304. A limiting groove is evenly distributed around the periphery of the limiting plate 14. Two spring-loaded telescopic rods 15 are fixed on the inner wall of the limiting groove. The spring-loaded telescopic rod 15 consists of a telescopic rod one (small diameter), a telescopic rod two (large diameter), and its spring. One end of the telescopic rod one is nested with the inner wall of the telescopic rod two through a sealing block or sealing gasket. The spring is fitted outside the telescopic rod one and the telescopic rod two. A limiting block 16 is fixed on one end of the spring-loaded telescopic rod 15.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, when using it, the staff can replace the appropriate sealing block 1 according to the condition of the road pipe gallery. Select the appropriate sealing block 1 and thread the connecting hole 303 of the sealing block 1 to one end of the air column 304. The sealing plate 17 and sealing gasket 18 provided on the air column 304 ensure that the interface between the air column 304 and the sealing block 1 is completely sealed to avoid air leakage.

[0036] Then, the sealing block 1 is placed in the road pipe gallery through the inflatable column 304, which can play an auxiliary sealing role. At the same time, the limiting plate 14 set by the inflatable column 304 is located in the road pipe gallery. The limiting plate 14 is fixed to the inflatable column 304 by the spring sleeve telescopic rod 15 and the limiting block 16 to prevent displacement due to air pressure changes during inflation. When the sealing block 1 is subjected to external impact on the protective cover 204, the miniature air spring 202 absorbs the impact force through its own compression deformation.

[0037] During operation, one of the control valves 5 is opened, allowing gas to enter the filter box 7 from the input pipe 8 through the air pump. The gas passes through the filter screen 10 set in one of the filter frames 9 in the filter box 7 to remove particulate impurities, and then passes through the activated carbon screen 11 set in the other filter frame 9 to adsorb harmful substances, ensuring that the gas is clean. The purified gas enters the three-way pipe 4 through the delivery pipe 6 and control valve 5, and finally enters the inflation hole 302 through the inflation column 304, causing the inflatable sealing balloon 301 to expand.

[0038] When the inflatable plugging balloon 301 expands, it pushes open the protective cover 204. The protective cover 204 rotates and unfolds around the rotating rod 205. At the same time, the rotating rod 201 and rotating rod 203 set in the miniature gas spring 202 rotate in linkage. The inflatable plugging balloon 301 expands and fits against the inner wall of the pipe gallery to achieve a seal. It is easy to adapt to different pipe gallery sizes and shapes. It can still maintain a stable seal in complex environments such as high-pressure groundwater or gas. Then the open control valve 5 is closed.

[0039] During storage, the inflatable plugging balloon 301 can be discharged by turning on the vacuum pump and another control valve 5. During the discharge process, the inflatable plugging balloon 301 is stored in the protective groove of the plugging block 1. At the same time, the protective cover 204 rotates around the rotating rod 205 during storage. Meanwhile, the rotating rod 201 and rotating rod 203 set in the miniature gas spring 202 rotate in linkage, so that the protective cover 204 can close and cover the protective groove, preventing the inflatable plugging balloon 301 from being exposed to the external environment and reducing the maintenance needs caused by collision or corrosion.

[0040] After being stored, the liquid that seeps into the protective tank, such as rainwater or groundwater, can be discharged in time through the drainage hole 19 opened below the sealing block 1 to prevent the accumulation of liquid from corroding the internal components. The filter frame 9 is snapped into the filter box 7 by the snap-fit ​​block 12 and the sealing gasket 13, which makes it easy to disassemble and replace the filter screen 10 and the activated carbon screen 11, thus extending the service life of the device.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
