[0033] like Figure 4 As shown, preferably, the odor-proof sealing device includes two support bars 5, the two support bars 5 are respectively connected to the inner two sides of the pool opening, and the two sides of the flexible cover 3 are respectively overlapped on the two support bars 5.

[0034] Specifically, the support bars 5 are arranged along the length direction of the pool body 2, and the flexible covers 4 are respectively arranged on both sides of the interior of the pool opening, occupying a small space.

[0035] Preferably, the flexible cover 3 includes a plurality of cover plates 31 , which are arranged in sequence, and two adjacent cover plates 31 are connected by a sealing hinge.

[0036] Specifically, the sealing hinge includes multi-layer sealing strips and a sound-absorbing load-bearing hinge. The flexible cover 3 is composed of a plurality of cover plates 31 and can also be a polyvinylidene fluoride film (PVDF film) or a film of other materials.

[0037] like Figure 2 and Figure 5 As shown, preferably, both sides of the flexible cover 3 are rotatably connected to a plurality of guide wheels 6 , and the guide wheels 6 on both sides are in contact with the top of the work vehicle 1 .

[0038] Specifically, the guide wheel 6 can reduce the resistance of the flexible cover 3 to the working vehicle 1 .

[0039] Preferably, the thickness of the cover plate 31 is 60 mm, and a cavity is provided inside the cover plate 31 , which is filled with polyurethane.

[0040] Specifically, the interior of the cover plate 31 is filled with polyurethane, which is used to reduce the weight of the cover plate 31 while ensuring the strength of the cover plate 31.

[0041] Preferably, the deodorizing sealing device further comprises at least two supporting members 7 , and at least one supporting member 7 is connected to both sides of the work vehicle 1 . The supporting members 7 on both sides of the work vehicle 1 are used to support the flexible cover 3 .

[0042] Preferably, the side cover 4 is a polyvinylidene fluoride film.

[0043] Specifically, the polyvinylidene fluoride membrane (PVDF membrane) has the characteristics of heat resistance, aging resistance, and easy cleaning, and is suitable for sealing the pool opening of the pool body 2 for a long time.

[0044] Preferably, the anti-odor sealing device further comprises:

[0045] At least two distance measuring sensors 8, at least two distance measuring sensors 8 are respectively arranged on both sides of the working vehicle 1, and the distance measuring sensors 8 are used to measure the distance between the working vehicle 1 and the same side of the tank body 2;

[0046] The control box 9 is arranged on the work vehicle 1. The control box 9 is arranged outside the sealing cover formed by the flexible cover 3 and the side cover 4. The control box 9 is electrically connected to the work vehicle 1 and the distance sensor 8. The control box 9 is used to receive the distance signal measured by the distance sensor 8 and send instructions to the direction control mechanism of the work vehicle 1 according to the preset deviation value.

[0047] Specifically, the distance measuring sensor 8 can be a laser rangefinder, and the control box 9 is arranged on the outside of the sealing cover formed by the flexible cover 3 and the side cover 4 to prevent the control box 9 from being contaminated and corroded, causing damage and malfunction of internal components. The running and stopping time of the work vehicle 1 can be set through the control box.

[0048] In order to avoid the problem of the work vehicle 1 easily running off the track, the present application sets at least one distance measuring sensor 8 on both sides of the work vehicle 1. When the distance sensor 8 detects that the deviation distance of the work vehicle 1 exceeds the preset deviation value, the control box 9 can control the work vehicle 1 to move in the opposite direction of the deviation. When the deviation distance is reduced to within the preset deviation value, the work vehicle 1 will move in the originally set direction, thereby ensuring that the work vehicle 1 can automatically correct itself in time after deviation occurs.

[0049] Work vehicle 1 includes:

[0050] vehicle body;

[0051] Two travel motors 10 are respectively provided on both sides of the vehicle body. The two travel motors 10 are respectively used to drive the wheels on both sides of the vehicle body to rotate. The distance measuring sensor 12 on the same side is electrically connected to the wheel through the control box 14.

The control box 9 is used to receive the position signal measured by the travel switch 11 and determine the position of the working vehicle 1.

[0053] Specifically, the distance between the two sides of the work vehicle 1 and the two sides of the pool body 2 is detected in real time by the distance measuring sensor 8, and the side of the work vehicle 1 that moves faster or slower is determined. When the deviation distance exceeds the preset deviation value, the travel motor 10 on the faster side stops working, and the travel motor 10 on the other side continues to move. When the deviation distance is reduced to the preset deviation value, the travel motor 10 continues to run. At the same time, the distance between the two ends of the work vehicle 1 and the two ends of the pool body 2 can also be detected by the travel switch 11 to judge the position of the work vehicle 1, and obstacles can be set at specific locations at both ends of the pool body 2. When the travel switch 11 cannot detect the obstacle, it means that the work vehicle has deviated, and it can be calibrated with the distance measuring sensor 8 to ensure that the work vehicle 1 can be automatically corrected in time after the deviation occurs.

[0054] Preferably, the odor-proof sealing device also includes a toxic gas concentration detection probe 12, which is arranged on the work vehicle 1. The toxic gas concentration detection probe 12 is arranged in a sealed cover formed by the flexible cover 3 and the side cover 4. The control box 9 is electrically connected to the gas concentration detection probe 12. The control box 9 is used to receive the toxic gas concentration signal detected by the toxic gas concentration detection probe 12, and can display the concentration value on the display screen of the control box 9.

[0055] Specifically, the toxic gas concentration detection probe 12 is a hydrogen sulfide detection probe. When the work vehicle 1 fails, the control box 9 can display an alarm message. The maintenance personnel observe the hydrogen sulfide concentration fed back by the hydrogen sulfide detection probe in the sealed cover on the display screen of the control box 9, so as to prepare for equipment maintenance in advance. During maintenance, the side covers 4 on both sides of the work vehicle can be opened for ventilation. The hydrogen sulfide concentration drops below the safe value before personnel can enter for maintenance.

[0056] In summary, when the odor-proof sealing device of the present invention is implemented, the control box 9 controls the work vehicle 1 to move forward and backward, and the flexible cover 3 can be continuously arched with the movement of the work vehicle 1, and the flexible cover 3 itself will not move horizontally. The flexible cover 3 will always cover the pool mouth. At the same time, side covers 4 are connected to both sides of the work vehicle 1, and the covers 4 on both sides respectively block the arched mouth formed by the flexible cover 3 and the two sides of the pool body 2. Then, during the movement of the work vehicle, the sealing cover formed by the flexible cover 3 and the covers on both sides 4 will always close the pool body 2, and has good sealing performance to achieve odor prevention. At the same time, when the work vehicle 1 is a mud-discharging bridge vehicle, the work vehicle 1 will be able to complete the sand suction or mud discharge work in a closed state.

[0057] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
