[0045] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0046] Example 1

[0047] A manhole sealing shell for a tank truck cleaning device, such as Figures 1 to 3 As shown, a housing 100 is provided with a plurality of steps 150 for adapting to manholes of different sizes and a plurality of sealing strips 130, the sealing strips 130 are fixedly assembled around the outer surface of the housing 100, and the sealing strips 130 are located on the lower surface of the steps 150. An accommodating cavity 140 for accommodating a plurality of external drive components is formed inside the housing 100. The outer diameters of the plurality of steps 150 are gradually reduced from top to bottom.

[0048] It should be noted that the present invention defines the ground direction as downward when the external tanker cleaning device is operating normally. The manhole sealing shell of the present invention has a plurality of steps 150, and the outer diameters of the steps 150 decrease from top to bottom. Therefore, when facing manholes of different sizes, the manhole sealing shell of the present invention is vertically inserted into the manhole, and the manhole can be sealed when the edge of the manhole abuts against the corresponding step 150. This embodiment is described by taking two steps 150 as an example.

[0049] The manhole sealing shell of the utility model is also provided with a support plate 200 and a closing plate 300 for carrying the external drive assembly. The support plate 200 is fixedly arranged on the inner wall surface of the accommodating cavity 140, and the closing plate 300 is fixedly assembled on the inner wall surface of the accommodating cavity 140, and the support plate 200 is located above the closing plate 300. The support plate 200 is a cross-shaped support plate 200, such as Figure 4 The closing plate 300 is a circular closing plate 300, such as Figure 5 .

[0050] It should be noted that the cross-shaped structure support plate 200 of the utility model can also make way for the external cleaning liquid inlet pipe, so that the external cleaning liquid inlet pipe can be connected to the cleaning liquid flow channel 330 inside the closing plate 300.

[0051] The support plate 200 is provided with a first through hole 210, a second through hole 220 and two third through holes 230; the first through hole 210 is located at the center of the support plate 200, the second through hole 220 and the two third through holes 230 are distributed in an equilateral triangle, and the first through hole 210 is located at the midpoint of the line connecting the two third through holes 230.

[0052] The center of the closing plate 300 is provided with a fourth through hole 310 and two fifth through holes 320.

Figure 6 and Figure 7 .

[0053] It should be noted that the manhole sealing shell of the utility model is an accessory in the external tanker cleaning device. This accessory serves as an assembly support shell, so that the external cleaning arm 400 and the waste liquid suction arm 500 are fixedly inserted into the interior of the manhole sealing shell, and then when the tanker cleaning device is working, the external cleaning arm 400 and the waste liquid suction arm 500 are fixed inside the tanker. Moreover, because the external cleaning arm 400 is unfolded and folded, it needs to be equipped with a set of drive components separately, and the waste liquid suction arm 500 needs to be telescopic to suck the waste liquid inside the external tanker, and it also needs to be equipped with another set of drive components separately. Therefore, the accommodating chamber 140 of the manhole sealing shell of the utility model can accommodate two sets of drive components, and the support plate 200 and the closing plate 300 respectively carry the transmission components corresponding to the drive components. Moreover, the first through hole 210, the second through hole 220, the two third through holes 230, the fourth through hole 310 and the two fifth through holes 320 are through holes through which the functional components of the external tanker cleaning device pass.

[0054] It should also be emphasized that the invention point of the present utility model is the structure of the manhole sealing shell, and the specific structure and working principle of the external cleaning arm 400, the waste liquid suction arm 500 and the two sets of drive components do not belong to the protection content of the present utility model.

[0055] The housing 100 is further provided with an assembly ring 110 for sealing and fixing with the closing plate 300 . The assembly ring 110 is integrally fixed to the inner wall surface of the accommodating cavity 140 , and the closing plate 300 is sealing and fixedly assembled on the lower surface of the assembly ring 110 .

[0056] The manhole sealing shell for the tank truck cleaning device of the present utility model is also provided with a fixed assembly part 120 for connecting with an external mobile device, and the fixed assembly part 120 is integrally connected to the upper surface of the shell 100. The fixed assembly part 120 is used to assemble with the external mobile device to drive the manhole sealing shell, and the external cleaning arm 400 and the waste liquid suction arm 500 to move as a whole after use.
