[0002] An underground comprehensive pipeline corridor is a public tunnel built underground in the city for the centralized laying of municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas. The ground attachments are facilities such as outlets, imports and exports, and vents. With the development of the city, the ground space is crowded, and it is difficult to lay lines. Too many lines will affect the appearance of the city. Therefore, they are buried underground and laid in a centralized manner, which can effectively prevent the "zipper road" phenomenon and eliminate the need for staff to repeatedly excavate the road surface. All kinds of pipelines can be repaired, maintained, expanded, and renovated in the pipeline corridor, which greatly reduces the pipeline repair time. The comprehensive pipeline corridor is an important infrastructure to ensure the operation of the city.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-5 As shown, an underground pipe gallery survey and collection device comprises: an underground pipe gallery body 1, a built-in slot 2 is provided at the bottom of the underground pipe gallery body 1; a sampling mechanism 3, the sampling mechanism 3 is arranged inside the built-in slot 2; wherein the sampling mechanism 3 comprises a sampling component 31 arranged inside the underground pipe gallery body 1, an operating component 32 is arranged at the lower end of the sampling component 31, and the operating component 32 is located inside the built-in slot 2;

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the sampling assembly 31 includes two electric push rods 311 fixedly connected to the inner bottom wall of the underground tunnel body 1 and a fixed tube 313 fixedly connected to the inner wall of the underground tunnel body 1, the upper end of the electric push rod 311 is fixedly connected to the cross bar 312, the inner wall of the fixed tube 313 is slidably connected to the piston 315, the inner wall of the piston 315 is fixedly connected to the inner tube 314, the inner tube 314 is fixedly connected to the lower end of the cross bar 312, the surface of the fixed tube 313 is connected to a plurality of sampling tubes 316, the end of the sampling tube 316 is provided with a plug 317, the inner wall of the fixed tube 313 is provided with a rubber plug 319, the lower end of the rubber plug 319 extends to the lower end of the fixed tube 313, the lower end of the inner tube 314 is provided with a second air hole 3110, and the surface of the inner tube 314 is provided with a first air hole 318. The device can drive the electric push rod 311 regularly, so that the electric push rod 311 can drive the inner tube 314 to move upward synchronously through the cross bar 312, so that the piston 315 at the end of the inner tube 314 moves upward on the inner wall of the fixed tube 313, at this time, a low pressure is formed between the piston 315 and the rubber plug 319, so that the rubber plug 319 moves upward under the action of air pressure, and when liquid is deposited on the inner side of the built-in tank body 2, the deposited liquid is absorbed into the fixed tube 313 through the lower end of the fixed tube 313, and at the same time, the electric push rod 311 can be driven multiple times to make the piston 315 move up and down multiple times inside the fixed tube 313;

[0025] Since the lower end of the rubber plug 319 is tapered, the external liquid is gradually absorbed under the action of multiple driving of the electric push rod 311. At the same time, when the piston 315 moves downward, the rubber plug 319 blocks the lower end of the fixed tube 313, and under the action of the opening of the second air hole 3110 and the first air hole 318, the water is directed to the top of the piston 315, and then when the piston 315 moves upward, it is guided to the inside of the sampling tube 316. By observing the sampling tube 316, the collection sample of the internal accumulated liquid can be obtained, wherein the gas circulation speed of the second air hole 3110 and the first air hole 318 is lower than the suction speed of the lower end of the fixed tube 313, so that the effect of absorbing the accumulated liquid is maintained;

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the operating component 32 includes a round rod 321 arranged on the inner wall of the built-in groove body 2, an eccentric wheel 323 is fixedly connected to the surface of the round rod 321, the eccentric wheel 323 is eccentrically arranged, and an operating handle 322 is fixedly connected to the end of the round rod 321. A bottom groove 324 is opened inside the built-in groove body 2, the round rod 321 is located inside the bottom groove 324, and a cover plate 325 is arranged above the operating handle 322, and the cover plate 325 is arranged on the inner side of the bottom groove 324. When collecting internal accumulated liquid, the straight surface of the eccentric wheel 323 on the surface of the round rod 321 can be made to face upward, and at this time, it will not contact the rubber plug 319. When investigation and observation are required, or a large amount of liquid flows in, 322 can be turned 180 degrees by manual flipping operation, and the curved surface of the eccentric wheel 323 is driven by the round rod 321 to push the rubber plug 319 upward. At this time, the liquid in the fixed tube 313 can flow out freely, and the internal imprint of the fixed tube 313 can be used for auxiliary investigation to determine the degree of liquid accumulation inside the underground tunnel body 1.

[0027] When the utility model is in use, the device drives the electric push rod 311 regularly, and the electric push rod 311 drives the inner tube 314 to move upward synchronously through the cross bar 312, and the piston 315 at the end of the inner tube 314 moves upward on the inner wall of the fixed tube 313, and a low pressure is formed between the piston 315 and the rubber plug 319. Under the action of air pressure, the rubber plug 319 moves upward accordingly, and when liquid is deposited on the inner side of the built-in groove body 2, the deposited liquid is absorbed into the fixed tube 313 through the lower end of the fixed tube 313. By driving the electric push rod 311 multiple times, the piston 315 moves up and down multiple times inside the fixed tube 313, and the external liquid is gradually absorbed. By observing the sampling tube 316, a sample of the internal accumulated liquid is obtained. The gas circulation speed of the second air hole 3110 and the first air hole 318 is lower than the suction speed of the lower end of the fixed tube 313, so as to maintain the effect of absorbing the accumulated liquid. When collecting the internal accumulated liquid.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
