[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-Figure 6A rear ladder of a liquid tank truck shown in the figure comprises a liquid tank truck 1, a top plate 2 is fixedly connected to the top of the liquid tank truck 1, a uniformly distributed enclosure 3 is fixedly connected to the top of the top plate 2, a water retaining plate 4 is fixedly connected to one side of the enclosure 3, two oppositely distributed drainage pipes 9 are inserted and fixedly connected to one side of the water retaining plate 4, a uniformly distributed pedal 5 is fixedly connected between the two oppositely distributed drainage pipes 9, a uniformly distributed friction-increasing plate 51 is fixedly connected to the top of the pedal 5, and the outer wall of the pedal 5 is provided with uniformly distributed through holes 52.

[0024] In the above arrangement, the top plate 2 provides a platform for workers to operate, the friction is increased by arranging the friction-increasing plate 51, and the overall cost is reduced by arranging the through hole 52. The advantage of such an arrangement is that it is more convenient for workers to crawl up and down.

[0025] A drainage assembly is connected to one side of the drain pipe 9, and the drainage assembly is used to discharge rainwater and leaked materials on the inner side of the enclosure 3, and at the same time notify the staff of the material leakage. The drainage assembly is connected to the liquid tank truck 1, and the drainage assembly includes a drain pipe 2 10 fixedly connected to one side of the drain pipe 9, a fixed plate 6 is inserted and fixedly connected to the top of the drain pipe 9, and the fixed plate 6 is fixedly connected to the top of the top plate 2, a liquid storage barrel 12 is inserted and fixedly connected to one side of the drain pipe 2 10, and a sewage ball valve 11 is fixedly installed at one end of the drain pipe 9 away from the fixed plate 6, and a liquid tank 7 is opened on one side of the fixed plate 6.

[0026] In the above arrangement, the sewage ball valve 11 is in an open state on rainy days, and rainwater flows from the liquid tank 7 into the interior of the drainage pipe 9 and is then discharged through the sewage ball valve 11, thereby preventing rainwater from accumulating inside the enclosure 3. When there is material leakage, the sewage ball valve 11 can also be opened to discharge the material into the corresponding container, thereby preventing the material from flowing to the road surface and polluting the environment. In addition, this structure only requires welding a section of connecting pipe on the vertical pipe of the rear ladder, and the welding amount is much smaller than welding the downpipe fixing ring on the head. The vertical pipe of the ladder is directly used as a drainage pipe, thereby saving the material of the downpipe and saving the cost.

[0027] In the above setting, when the sewage ball valve 11 is in a closed state, the material leaks and is concentrated in the drain pipe 9. After reaching a certain amount, it enters the drain pipe 2 10 through the drain pipe 9, and then enters the interior of the liquid storage barrel 12 through the drain pipe 2 10. The advantage of this setting is that when the sewage ball valve 11 is in an open state, the liquid will not enter the interior of the liquid storage barrel 12.

[0028] The drain pipe 1 9 includes an inclined section 1 91 , a vertical section 92 and an inclined section 2 93 which are sequentially connected from top to bottom, and the inclined section 1 91 , the vertical section 92 and the inclined section 2 93 are respectively connected to the fixed plate 6 , the drain pipe 2 10 and the sewage ball valve 11 .

[0029] In the above arrangement, since the inclined section 1 91 and the inclined section 2 93 are in an inclined state, the flow velocity of rainwater increases when passing through the two places. The advantage of such an arrangement is that the flow velocity of liquids such as rainwater is increased.

[0030] The positions of the liquid tank 7 and the drain pipe 9 correspond and the two are connected. A lightweight hole 8 is opened on one side of the fixing plate 6.

[0031] The advantage of such an arrangement is that the fixing effect on the drain pipe 9 is enhanced.

[0032] The inner wall of the liquid storage barrel 12 is slidably connected with a movable cylinder 13, and the bottom of the movable cylinder 13 is connected with two reset members 14 distributed in opposite directions, and the two reset members 14 are fixedly connected to the inner wall of the liquid storage barrel 12, and a sensor 15 is arranged between the two reset members 14 distributed in opposite directions, and the sensor 15 is fixedly connected to the inside of the liquid storage barrel 12, and the reset member 14 includes an L-shaped rod 141 fixedly connected to the inner wall of the liquid tank truck 1, and the outer wall of the L-shaped rod 141 is fixedly connected with a baffle 142, and the top of the L-shaped rod 141 is fixedly connected with a movable ball 144, and the outer wall of the movable ball 144 is rotatably connected with a support plate 145, and the outer wall of the L-shaped rod 141 is sleeved with a spring 143, and the spring 143 is fixedly connected between the movable ball 144 and the baffle 142.

[0033] In the above arrangement, the liquid enters the liquid storage barrel 12 through the drain pipe 10 and then enters the movable cylinder 13. When the liquid in the movable cylinder 13 accumulates to a certain amount, its weight will be fed back to the reset member 14 supporting the movable cylinder 13. Since the bottom of the movable cylinder 13 is arc-shaped and smaller than the whole, when the support plate 145 tilts around one side of the movable ball 144, the movable cylinder 13 as a whole will slide down. At the same time, the spring 143 will be compressed and deformed, making the sliding process of the movable cylinder 13 more stable. When the bottom of the movable cylinder 13 contacts the sensor 15, the staff will know that the material has leaked. The advantage of this arrangement is that the staff will quickly know after the material leaks and respond to it, thereby reducing the degree of loss during transportation.

[0034] Working principle:

[0035] The top plate 2 provides a platform for workers to climb up and operate. The friction is increased by setting the friction increasing plate 51, and the overall cost is reduced by setting the through hole 52. The advantage of such a setting is that it is more convenient for workers to crawl up and down.

[0036] On rainy days, the sewage ball valve 11 is in an open state, and rainwater flows from the liquid tank 7 into the interior of the drainage pipe 9, and then is discharged through the sewage ball valve 11, so as to prevent rainwater from accumulating inside the enclosure 3. When there is material leakage, the sewage ball valve 11 can also be opened to discharge the material into the corresponding container, so as to prevent the material from flowing to the road surface and polluting the environment. In addition, this structure only needs to weld a section of connecting pipe on the vertical pipe of the rear ladder, and the welding amount is much smaller than welding the downpipe fixing ring on the head. The vertical pipe of the ladder is directly used as a drainage pipe, which also saves the material of the downpipe and saves the cost.

[0037] When the sewage ball valve 11 is in a closed state, the material leaks and collects in the drainage pipe 1 9. When a certain amount of material is collected, it enters the drainage pipe 2 10 through the drainage pipe 1 9, and then enters the interior of the liquid storage barrel 12 through the drainage pipe 2 10. The advantage of this arrangement is that when the sewage ball valve 11 is in an open state, the liquid will not enter the interior of the liquid storage barrel 12.

[0038] After the liquid enters the liquid storage barrel 12 through the drain pipe 10, it will enter the movable cylinder 13. When the liquid in the movable cylinder 13 accumulates to a certain amount, its weight will be fed back to the reset part 14 supporting the movable cylinder 13. Because the bottom of the movable cylinder 13 is arc-shaped and smaller than the whole, when the support plate 145 tilts around one side of the movable ball 144, the movable cylinder 13 as a whole will slide down. At the same time, the spring 143 will be compressed and deformed, making the sliding process of the movable cylinder 13 more stable. When the bottom of the movable cylinder 13 contacts the sensor 15, the staff will know that the material has leaked. The advantage of this arrangement is that the staff will quickly know after the material leaks and respond to it, thereby reducing the degree of loss during transportation.
