The specific working process of the application is as follows:

refer to fig. 5, 12; the fixed seat 94 is installed on the truss car body 92 through bolts, one end of the sand suction pipe and one end of the protective frame 95 enter the first open area 2 through the partially opened spring plate, the other end of the sand suction pipe and the protective frame are fixedly installed on the fixed seat 94 through bolts, waste water needing to be sucked in the first open area 2 is contained, and the sand suction pipe sucks sand while the truss car moves; when the truss moves, the protection frame 95 pushes each spring plate plane to rotate, for example, the first spring plate 41 is pushed to rotate to a side plane, the first auxiliary rod 411 rotates at the same time, because the torsion spring 6 is sleeved and fixed on the first auxiliary rod 411, the body of the torsion spring 6 also rotates along with the rotation, but the top end suspension buckle and the bottom end suspension buckle of the torsion spring 6 are clamped in the first limit plate 412 (the upper and lower end suspension buckles of the torsion spring 6 are only clamped in the first limit plate 412, the suspension buckles can be not fixed in the first limit plate 412), so the upper suspension buckle can also generate torsion along with the body of the torsion spring 6 to generate a rotary force, but cannot be separated from the first limit plate 412, when the truss moves away, the protection frame 95 leaves, loses the pushing force to the first spring plate 41, and at this time, the first spring plate 41 rotates under the action of the rotary force of the torsion spring 6, returning again to the initial position covers and closes the space above the first open area 2. Similarly, the working principle of other spring plates is also the same. Therefore, the sand suction device can open an effective space on the open area 2 to enable the truss vehicle to suck sand, and the truss vehicle is unlikely to be like a traditional integral capping mode, for example, a sunlight room, an anti-hanging film, an inflation film and the like are adopted, and the truss vehicle is always in a closed space and is easy to corrode.

Wherein reference is made to fig. 7-10; the first spring plate 41, the second spring plate 42, the third spring plate 43 and the fourth spring plate 33 are distributed in a staggered manner and are positioned on different plane heights, and as long as the length and the width of each plate are controlled, the plates cannot touch each other; this is also one of the core ideas of the present application.

It should be noted that:

1: reference is made to fig. 7-10; because each spring plate (first spring plate 41, second spring plate 42, third spring plate 43, fourth spring plate 44, fifth spring plate 51, sixth spring plate 52, seventh spring plate 53, eighth spring plate 54) in this application is the dislocation distribution, and corresponding some spring plates exist different plane height, consequently open regional one 2's upper space is not complete closed seal state, there is narrow and small gap, but under general condition, the aeration grit chamber can set up the fan, through adjusting the fan frequency, the space that makes the waste gas collect is negative pressure state, make inside harmful gas easily outwards not diffuse to the environment in.

2. Refer to fig. 12; in the present application, in general, the protection frame 95 can move back and forth in two directions in the first opening area 2, and at this time, each spring plate receives thrust in different directions, and the torsion of the torsion spring 6 also generates turning force in different directions, so that each spring plate can rotate in different directions and then turn. Meanwhile, for the convenience of maintenance, the fixing seat 94, the sand suction pipe, the protective frame 95 and the truss car body 92 are fixed by bolts, so that the fixing seat, the sand suction pipe, the protective frame 95 and the truss car body 92 can be detached from each other, and the truss car can be reassembled after the maintenance is finished.

3. Refer to fig. 12; the protection frame 95 in the device can be inserted into the first open area 2 all the time without being detached from the fixed seat 94; even if the protection frame 95 and the sand suction pipe are inserted into the first open area 2 all the time, although a plurality of spring plates around the protection frame are in a constantly opened state, the inside of the first open area is slightly negative pressure, so that the phenomenon of gas overflow is avoided, and the protection frame 95 and the sand suction pipe can be detached from the fixing seat 94 for convenient maintenance.

4. The working principle or working process of the invention is as follows: the regional width of sand suction pipe of aeration grit chamber purlin car is about 500mm usually, to the problem of adding the lid difficulty that arouses because of the purlin car removes, this scheme provides a simple structure, sealed effectual spring board and covers waste gas collection device. The coverage area of the sealing spring plates can meet the moving area of the sand suction pipe, the adjacent sealing spring plates are arranged in a staggered mode, the sealing spring plates are made of stainless steel materials, and each plate is provided with a fixed spring; the sealing spring plates are fixed on the upper fixing plate and the lower fixing plate in a staggered mode respectively, so that the sealing spring plates are prevented from colliding with each other during rotation; when the truss car moves forwards, the sealing spring plate rotates under the action of thrust, and the truss car smoothly passes through the rear spring plate and recovers to the horizontal position under the action of elastic force, so that the upper part of the liquid level of the water pool is in a closed state. For the area without sand suction pipe (the second open area 7), a fixed glass fiber reinforced plastic plate can be used for covering due to no mobile equipment obstruction, and an exhaust gas collecting pipeline (an exhaust gas collecting pipe 82) is arranged on one side of the covered pool, so that the exhaust gas generated in the pool can be effectively collected.

It should be noted that, in the present invention, the terms "upper", "lower", "left", "right", "front", "back", etc. are used for the sake of clarity only, and are not used to limit the scope of the present invention, and the relative relationship changes or adjustments may be made without substantial technical changes.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
