Technical Field

[0001] This utility model belongs to the technical field of cleaning equipment, specifically, it relates to a tank truck internal cleaning mechanism. Background Technology

[0002] In existing technologies, grain and oil companies inspect and clean the interior of tank trucks before loading. Tank trucks are generally over 10 meters long, and most only have one entrance at each end of the top. For reinforcement, they are divided into five or six compartments by partitions, with 80cm diameter through-holes in the middle of the partitions. To inspect or clean, one needs to penetrate about 4-5 meters into the compartment from one side. Manual inspection and cleaning are time-consuming and labor-intensive. Existing devices do not effectively address the issue of lateral access into the compartment. Some devices use multi-stage telescopic cylinders or electric cylinders, but these are structurally complex, and the equipment is constantly exposed to moisture, raising concerns about its stability and reliability.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0004] Therefore, in order to solve the above problems, this utility model provides a tanker truck internal cleaning mechanism. Utility Model Content

Detailed Implementation

[0018] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example 1

[0019] Please see Figure 1 and Figure 2 According to an embodiment of the present utility model, a tank truck internal cleaning mechanism includes a horizontal plate 1, which is adapted to a fixed platform on the roof of the vehicle to facilitate the fixing of the entire cleaning mechanism. An electric telescopic rod 2 is installed at the bottom end of the horizontal plate 1. The electric telescopic rod 2 can adjust the vertical position of the cleaning mechanism and extend into the tank. A mounting frame 3 is fixedly installed at the bottom end of the electric telescopic rod 2. A cleaning mechanism 4 is installed on the mounting frame 3, which facilitates subsequent cleaning operations on the tank truck. Please see Figure 1 and Figure 2 The cleaning mechanism 4 includes a telescopic main pipe 41 fixed on the mounting frame 3. One end of the telescopic main pipe 41 is provided with several telescopic branch pipes 42. One end of the telescopic branch pipe 42 is fixedly installed with a connecting pipe 5. One end of the connecting pipe 5 is fixedly installed with a nozzle 6. The telescopic branch pipes 42 and the telescopic main pipe 41 can move relative to each other. Through the action of water pressure, the entire cleaning mechanism 4 can be extended laterally, which is convenient for cleaning the inside of the tanker. The nozzle rotates 360 degrees on its own and sprays water to both sides, and the recoil is balanced. Please see Figure 1 and Figure 2 A pull rope 7 is connected above the telescopic main pipe 41 and the telescopic branch pipe 42. One end of the pull rope 7 is connected to the recovery assembly 8. The cleaning mechanism 4 extends laterally by the pressure of the cleaning fluid. The position control of the telescopic branch pipe 42 extending laterally and retracting is achieved by the pull rope on the recovery assembly 8.

[0020] Please see Figure 1 and Figure 2The telescopic main pipe 41 and the telescopic branch pipe 42 have a through internal cavity channel, and the interiors of the telescopic main pipe 41 and the telescopic branch pipe 42 are connected to form a water supply channel to ensure the flow of cleaning fluid. The cleaning fluid is delivered to the connecting pipe 5 and the nozzle 6 through the telescopic main pipe 41 and the telescopic branch pipe 42. The integrated water circuit design reduces the number of external pipes and improves the structural compactness. The telescopic main pipe 41 and the telescopic branch pipe 42 use carbon fiber telescopic rods, which have the advantages of being lightweight and small in size.

[0021] Please see Figure 1 and Figure 2 The top ends of the telescopic main pipe 41 and the telescopic branch pipe 42 are both fixedly installed with a first limiting ring 43, and the bottom ends of the telescopic main pipe 41 and the telescopic branch pipe 42 are both fixedly installed with a second limiting ring 44. The pull rope 7 passes through the first limiting ring 43, and one end of it is fixedly connected to the first limiting ring 43 located at the top of the end telescopic branch pipe 42. The first limiting ring 43 is used to guide and limit the pull rope 7 to prevent the pull rope from deviating during the telescopic process.

[0022] Please see Figure 1 and Figure 2 The recycling component 8 includes a device frame 81 fixedly installed at the top of the horizontal plate 1. A rotating rod 82 is rotatably connected to the device frame 81. A motor 83 is fixedly installed on one side of the device frame 81. The output end of the motor 83 is connected to one end of the rotating rod 82. One end of the pull rope 7 is fixedly installed on the rotating rod 82. The motor 83 provides the power source. When the motor 83 rotates forward, it drives the rotating rod 82 to rotate. The rotation of the rotating rod 82 can cause the pull rope 7 to wrap around the rotating rod 82, which in turn can drive the telescopic branch pipe 42 to retract. When the telescopic branch pipe 42 extends, the motor 83 reverses and releases the pull rope of length D. At this time, the telescopic branch pipe 42 will be extended by water pressure, and the extension distance is D, thereby controlling the movement of the nozzle in the tank and realizing the comprehensive cleaning of the tank.

[0023] Please see Figure 1 and Figure 2 One end of the telescopic main pipe 41 is connected to the water injection pipe 9, and the other end of the water injection pipe 9 is connected to the external cleaning fluid. The water injection pipe 9 can achieve continuous water supply operation.

[0024] The working principle of this embodiment is as follows: The horizontal plate 1 is fixed to the fixed platform on the top of the tank truck. The cleaning mechanism 4 is adjusted by the electric telescopic rod 2 to lower it into the tank. Then the cleaning fluid is injected through the water injection pipe 9 and then transported into the telescopic main pipe 41. Since the telescopic main pipe 41 and the telescopic branch pipe 42 have a through cavity channel, water will enter the telescopic branch pipe 42. Under the action of water pressure, the telescopic branch pipe 42 will be extended, carrying the nozzle 6 forward. The nozzle 6 rotates 360 degrees on its own and sprays water to both sides. The recoil is balanced, and the nozzle 6 is subjected to the water pressure, and the whole is subjected to the forward force. After the cleaning is completed, the motor 83 is started. The motor 83 drives the rotating rod 82 to rotate. The rotation of the rotating rod 82 allows the pull rope 7 to be wound around the rotating rod 82. The pull rope 7 is pulled by the first limiting ring 43 to retract and extend the outermost first limiting ring 43, thereby controlling the specific position of the nozzle 6 in the tank. Example 2

[0025] Please see Figure 1 and Figure 2 A water supply pipe 10 is provided below the telescopic main pipe 41 and the telescopic branch pipe 42. One end of the water supply pipe 10 is connected to the telescopic main pipe 41, and the water supply pipe 10 passes through the second limiting ring 44. Its other end is connected to the connecting pipe 5. The cleaning fluid flows through the cavity in the telescopic main pipe 41 to the water supply pipe 10, and then is transported through the water supply pipe 10 to the connecting pipe 5 and the nozzle 6.

[0026] The working principle of this embodiment is as follows: water from the water injection pipe 9 is injected into the telescopic main pipe 41, then flows into the water supply pipe 10, and then flows out into the connecting pipe 5. It is then sprayed out through the nozzle 6. With the action of water pressure, the nozzle 6 can be pushed forward, which in turn can drive the telescopic main pipe 41 and the telescopic branch pipe 42 to extend.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
