[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model discloses a tank truck cleaning device, including a cleaning chamber 1 and a controller 2 located outside the cleaning chamber 1, as well as a cleaning fluid mixing component 3, a safety protection component 4, a top frame adjustment component 5, and a cleaning component 6, wherein:

[0025] Two symmetrical chutes 11 are provided at the bottom of the cleaning chamber 1. The chutes 11 are connected by the drainage channel 12 and extend to the outside.

[0026] Please refer to the appendix. Figure 3 The cleaning solution preparation component 3 includes a mixing tank 31. The mixing tank 31 is equipped with a regular water tank 32 and a chemical cleaning solution storage tank 33 on both sides. A water pump 34 is connected between the regular water tank 32 and the mixing tank 31. A metering pump 35 is connected between the chemical cleaning solution storage tank 33 and the mixing tank 31. Specifically, the metering pump 35 can control whether the chemical cleaning solution is added to the mixing tank 31 and the flow rate, so as to cope with the cleaning of different materials.

[0027] Please refer to the appendix. Figure 4The safety protection component 4 includes a negative pressure plate 41, with a vacuum tube 42 connected to the top of the negative pressure plate 41. A vacuum generator 43 is connected to one side of the vacuum tube 42, and the vacuum generator 43 is connected to a vacuum pump 44. A recovery tank 45 is installed on one side of the vacuum pump 44. The vacuum pump 44 is installed on the top of the cleaning chamber 1. Specifically, the vacuum generator 43 can use the vacuum generated by the vacuum pump 44 to further generate a localized and faster vacuum suction effect, thereby improving the adsorption effect of the negative pressure plate 41. The extracted dust and volatile gases are collected in the recovery tank 45 for centralized treatment.

[0028] The mixing tank 31, the ordinary water tank 32, and the chemical cleaning solution storage tank 33 are all fixed to the mounting bracket 36 with screws. The mounting bracket 36 is fixed to the inner wall of the cleaning chamber 1 with bolts. The metering pump 35 is electrically connected to the controller 2.

[0029] In this embodiment, the vacuum pump 44 draws air from the inside of the cleaning chamber 1 through the vacuum tube 42, thereby generating negative pressure around the negative pressure plate 41. This allows volatile toxic gases and dust to be drawn in from the negative pressure plate 41, preventing leakage to the outside and causing injury to personnel. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 5 as well as Figure 6 The negative pressure plate 41 is located at the top of the inside of the cleaning chamber 1. The bottom surface of the cleaning chamber 1 is provided with several water inlet troughs 14. Guardrails 13 are symmetrically arranged between the chutes 11. Tank cars 7 are arranged between the guardrails 13. The tank cars 7 are provided with several water inlets 71. Specifically, the water inlet troughs 14 can guide the splashed cleaning liquid into the drainage ditch 12 to prevent it from overflowing from the cleaning chamber 1.

[0031] The top frame adjustment assembly 5 includes a top frame 51, the bottom of the top frame 51 is fitted with a sliding groove 11 and is slidably engaged, one end of the bottom of the top frame 51 is penetrated by a spiral shaft 52 and is helically engaged, and the other end of the bottom is penetrated by a sliding shaft 53 and is slidably engaged.

[0032] One end of the spiral shaft 52 is connected to the servo motor 54. The servo motor 54 is installed in the slide 11 and electrically connected to the controller 2. The two ends of the slide shaft 53 are fixed to the two ends of the slide 11. Specifically, the servo motor 54 can easily control the top frame 51 to slide back and forth, thereby matching the different water inlet 71 positions of the tank car 7.

[0033] The cleaning assembly 6 includes a booster pump 61. One end of the booster pump 61 is connected to the mixing tank 31 via a conduit, and the other end is connected to the spray pipe 62 via a flange. The spray pipe 62 passes through the top frame 51 and is fixed to the top frame 51 with screws. The bottom end of the spray pipe 62 is connected to a telescopic hose 63. Specifically, the telescopic hose 63 can extend and bend to cooperate with the nozzle 64 to move up and down and change the spray direction.

[0034] The bottom end of the telescopic hose 63 is connected to the nozzle 64. The top surface and outer wall of the nozzle 64 are provided with several spray holes 641. The two sides of the nozzle 64 are connected to the traction rope 65. The traction rope 65 passes through several traction rings 66 and connects to the roller 67. The roller 67 is installed on the traction motor 68. The traction motor 68 is fixed to the top frame 51 by bolts.

[0035] In this embodiment, one traction motor 68 rotates clockwise and the other rotates counterclockwise. The clockwise rotating traction motor 68 drives the roller 67 to wind up the traction rope 65. The traction rope 65 pulls the top of the nozzle 64 under the limit of the traction ring 66, thereby causing the nozzle 64 to bend in the direction of the clockwise rotating traction motor 68. Under the control of the two traction motors 68, the nozzle 64 can change its angle arbitrarily along the placement direction of the tank truck 7, which greatly improves the cleaning efficiency.

[0036] The working principle and usage process of this utility model are as follows: First, when the tank truck 7 enters the cleaning chamber 1, it can be positioned according to the position of the guardrail 13 so that the axial direction of the water inlet 71 is directly below the nozzle 64, so that the nozzle 64 can normally enter the interior of the tank truck 7 from the water inlet 71.

[0037] After the tank truck 7 comes to a stop, the controller 2 controls the servo motor 54 to rotate. The servo motor 54 drives the spiral shaft 52 to rotate. The spiral shaft 52 and the top frame 51 interact with each other, which in turn causes the top frame 51 to slide in the chute 11, bringing the nozzle 64 directly above the water inlet 71. Then, depending on the type of liquid transported by the tank truck 7, if it is ordinary material residue, the controller 2 selects the clean water cleaning mode on the control panel and presets the cleaning time. At this time, the metering pump 35 is turned off and the water pump 34 is turned on, drawing water from the ordinary water tank 32 into the mixing tank 31. Then, the water is introduced into the booster pump 61 through the water pipe to increase the pressure, thereby obtaining high-pressure water that enters the spray pipe 62.

[0038] During cleaning, the traction motors 68 on both sides rotate counterclockwise simultaneously, which causes the traction rope 65 wound around the roller 67 to be lowered simultaneously. The nozzle 64 moves vertically downward under the action of gravity and enters the internal space of the tank of the tanker 7 through the water inlet 71. High-pressure water is sprayed out from the nozzle 64 to spray and clean the inside of the tank. When the traction motor 68 changes the rotation direction, the nozzle 64 can be controlled to change the spray direction, thereby thoroughly cleaning the inside of the tank of the tanker 7.

[0039] When transporting liquids containing stubborn stains or chemical materials, select the chemical cleaning mode on the controller 2 and set the type and ratio of the chemical cleaning solution. The controller 2 simultaneously turns on the metering pump 35 and the water pump 34, and controls the flow rate of the metering pump 35 according to the preset ratio. The chemical cleaning solution and clean water are mixed in the mixing tank 31 to clean the tank truck 7.

[0040] When transporting flammable, explosive, toxic and harmful materials, the vacuum pump 44 and vacuum generator 43 are started before cleaning. The vacuum pump 44 draws air from the inside of the cleaning chamber 1 through the vacuum tube 42 to generate negative pressure around the negative pressure plate 41, so that the volatile toxic gases and dust are sucked in from the negative pressure plate 41 to prevent leakage to the outside and causing injury to personnel.
