[0046] The technical solution of the present invention is further described with reference to the following examples.

[0047] Example 1

[0048] A compartment type tank truck cleaning device, such as Figures 1 to 3 As shown, a main body 100 and a washing arm 200 are provided, and the washing arm 200 is assembled to the main body 100 .

[0049] The cleaning arm 200 is provided with a fixed plate 210, a multi-section curved tube assembly 220 for spraying cleaning liquid, a telescopic mechanism 230 for driving the multi-section curved tube assembly 220 to fold or stretch, a bending mechanism 240 for bending the telescopic mechanism 230 and the multi-section curved tube assembly 220 as a whole, and a rotating mechanism 250 for rotating the multi-section curved tube assembly 220, the telescopic mechanism 230 and the bending mechanism 240 as a whole. The rotating mechanism 250 is fixedly assembled on the fixed plate 210, and the multi-section curved tube assembly 220, the telescopic mechanism 230 and the bending mechanism 240 are all transmission-connected to the rotating mechanism 250, the telescopic mechanism 230 is fixedly connected to the multi-section curved tube assembly 220, and the bending mechanism 240 is transmission-connected to the telescopic mechanism 230.

[0050] The rotating mechanism 250 is provided with a first motor 251, a first gear 252 and a second gear 253. The first motor 251 is fixedly assembled on the fixed plate 210, the first gear 252 is fixedly connected to the motor shaft of the first motor 251, the second gear 253 is engaged with the first gear 252, and the multi-section bending tube assembly 220, the telescopic mechanism 230 and the bending mechanism 240 are all fixedly connected to the first gear 252.

[0051] It should be noted that the partition-type tank truck cleaning device of the present invention enters one of the partitions of the tank truck from the manhole. However, under the action of the rotating mechanism 250, the multi-section curved pipe assembly 220 is rotated 360 degrees, and then the multi-section curved pipe assembly 220 and the telescopic mechanism 230 are bent as a whole through the bending mechanism 240 to enter the through holes of the partition 510 at different angles. At the same time, the telescopic mechanism 230 is used to stretch the multi-section curved pipe assembly 220, so that the multi-section curved pipe assembly 220 extends into the interior of different partitions.

[0052] The multi-section curved pipe assembly 220 is provided with a fixed pipe 221, at least two movable pipes 222 and a spray head 223. One end of the fixed pipe 221 is fixedly connected to the second gear 253, and the other end of the fixed pipe 221 is rotatably connected to one of the movable pipes 222, and the multiple movable pipes 222 are rotatably connected from front to back. At the same time, the movable pipe 222 connected to the fixed pipe 221 is defined as the starting movable pipe 222, and the movable pipe 222 fixed to the telescopic mechanism 230 is defined as the end movable pipe 222. One end of the end movable pipe 222 is rotatably connected to the adjacent movable pipe 222, and the other end of the end movable pipe 222 is assembled with the spray head 223. Figure 4 shown.

[0053] It should be noted that the function of the multi-section movable tube 222 is to extend the cleaning radiation range when extended and reduce the overall length when folded. The fixed tube 221 is connected to the external cleaning pipe, and the cleaning liquid is transported from the fixed tube 221 and the multi-section movable tube 222 to the spray head 223.

[0054] The telescopic mechanism 230 is provided with a multi-section electric cylinder 231, a second motor 232 and a transmission assembly 233. The second motor 232 is fixedly assembled on the second gear 253. The motor shaft of the second motor 232 is fixedly connected to one end of the transmission assembly 233. The other end of the transmission assembly 233 passes through the second gear 253 and is transmission-connected to the multi-section electric cylinder 231. The telescopic end of the multi-section electric cylinder 231 is fixed to the end of the multi-section bending tube assembly 220.

[0055] When the multi-section electric cylinder 231 is extended, the multi-section bending tube assembly 220 is extended. When the multi-section electric cylinder 231 is shortened, the multi-section bending tube assembly 220 is folded.

[0056] It should be noted that the multi-section electric cylinder 231 is a common mechanical motion device, and those skilled in the art should be familiar with its operating principle. The present invention utilizes a transmission assembly 233 to dispose the second motor 232, which drives the multi-section electric cylinder 231, on a remote second gear 253. This has the advantages of reducing the volume and weight of the front end of the cleaning arm 200, increasing its telescopic flexibility for better cleaning, and preventing the second motor 232 from being splashed by cleaning fluid, thereby increasing its service life.

[0057] The cleaning arm 200 is further provided with an assembly rack 260 . The other end of the transmission assembly 233 and the fixed end of the multi-section electric cylinder 231 both extend into the interior of the assembly rack 260 , and the transmission assembly 233 is also assembled with the assembly rack 260 .

[0058] The transmission assembly 233 is provided with a second transmission rod 2331, a first bevel gear 2311, a first transmission gear set 2333 and a second transmission gear set 2334. The second transmission rod 2331 is transmission-connected to the motor shaft of the second motor 232. The first bevel gear 2311 is fixedly connected to the second transmission rod 2331. The first transmission gear set 2333 is meshed with the first bevel gear 2311. The first transmission gear set 2333 is meshed with the second transmission gear set 2334. The second transmission gear set 2334 is meshed with the second bevel gear 2332 of the multi-section electric cylinder 231. The multi-section electric cylinder 231 is also rotatably connected to the rotating shaft of the second transmission gear set 2334. Figure 5 .

[0059] The bending mechanism 240 is provided with a third motor 241, a nut tube 242, a first transmission rod 243 and a pulling assembly 244. The third motor 241 is fixedly assembled on the second gear 253. The nut tube 242 runs through the second gear 253 and is fixedly connected to the motor shaft of the third motor 241. One end of the first transmission rod 243 is threadedly connected to the nut tube 242. The other end of the first transmission rod 243 is located inside the assembly frame 260. The other end of the first transmission rod 243 is also transmission-connected to the pulling assembly 244. The pulling assembly 244 is assembled with the fixed end of the multi-section electric cylinder 231, as shown in FIG. Figure 6 .

[0060] When the third motor 241 rotates, the first transmission rod 243 moves upward, and the pulling assembly 244 is pulled upward, thereby driving the multi-section electric cylinder 231 to bend.

[0061] When the third motor 241 rotates in the reverse direction, the first transmission rod 243 moves downward, and the pulling assembly 244 is released downward, thereby driving the multi-section electric cylinder 231 to reset.

[0062] The working process of the present invention is as follows: the cleaning arm 200 enters one of the compartments from the manhole of the compartment-type tank truck 500, the rotating mechanism 250 rotates to make the multi-section bending pipe assembly 220 face the position of the through hole of the partition 510, and then the third motor 241 of the bending mechanism 240 rotates to drive the multi-section electric cylinder 231 to bend, so that the multi-section electric cylinder 231 and the spray head 223 are facing the through hole of the partition 510; the second motor 232 rotates to drive the multi-section electric cylinder 231 to extend, and the multi-section electric cylinder 231 is rotated. Driven by the second motor 232, the multi-section movable tube 222 extends, so that the cleaning arm 200 is extended, so that the spray head 223 and part of the movable tube 222 enter the interior of other compartments; when cleaning is completed, the second motor 232 rotates in the opposite direction to drive the multi-section electric cylinder 231 to shorten, and the multi-section movable tube 222 folds, so that the cleaning arm 200 is folded as a whole, and then the third motor 241 of the bending mechanism 240 rotates in the opposite direction to drive the multi-section electric cylinder 231 to reset, and finally the cleaning arm 200 is taken out from the manhole.

[0063] The cleaning arm 200 drives the multi-section curved tube assembly 220 to extend through the telescopic mechanism 230. At the same time, the telescopic mechanism 230 and the multi-section curved tube assembly 220 can be bent as a whole, passing through the through hole of the partition 510, so that the cleaning arm 200 can extend into other compartments to clean different compartments.

[0064] Example 2

[0065] A compartment type tank truck cleaning device, such as Figure 7-Figure 9 As shown, other features are the same as those of Example 1, and further have the following features: the main body 100 is provided with a first assembly frame 110, a second assembly frame 120 and a third assembly frame 130, the cleaning arm 200 can be raised and lowered to be assembled in the first assembly frame 110, the first assembly frame 110 can be raised and lowered to be assembled in the second assembly frame 120, and the second assembly frame 120 can be movably assembled in the third assembly frame 130.

[0066] The main body 100 is also provided with a first Z-axis moving mechanism 140, a second Z-axis moving mechanism 150, an X-axis moving mechanism 160 and a Y-axis moving mechanism 170. The first Z-axis moving mechanism 140 is fixedly assembled on the first assembly frame 110, and the transmission chain of the first Z-axis moving mechanism 140 is fixedly connected to the fixed plate 210. The second Z-axis moving mechanism 150 is fixedly assembled on the second assembly frame 120, and the transmission chain of the second Z-axis moving mechanism 150 is fixedly connected to the first assembly frame 110. The X-axis moving mechanism 160 is fixedly assembled on the second assembly frame 120, and the rotating teeth of the X-axis moving mechanism 160 are engaged with the rack of the third assembly frame 130. The Y-axis moving mechanism 170 is fixedly assembled on the third assembly frame 130.

[0067] It should be noted that the first Z-axis movement mechanism 140 enables the cleaning arm 200 to penetrate as far as possible to the bottom of the compartment, and the second Z-axis movement mechanism 150 is used to extend the first assembly frame 110 downward toward the manhole of the compartment-type tank truck 500. The X-axis movement mechanism 160 and the Y-axis movement mechanism 170 drive the cleaning arm 200 to move along the X- and Y-axes above the compartment-type tank truck 500, allowing it to flexibly move directly above the manhole of the compartment-type tank truck 500.

[0068] Compared with Example 1, this embodiment can be flexibly moved in the manhole of the compartment type tank truck 500.

[0069] Example 3

[0071] It should be noted that the image collector 300 of this embodiment can capture the positions of the through holes of the internal partition 510 of the compartment-type tank truck 500 in real time, so that the cleaning arm 200 can accurately enter the interior of other compartments.

[0072] Compared with the first embodiment, the cleaning arm 200 of this embodiment can be flexibly moved inside the compartment-type tank truck 500 .

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
