[0051] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0052] like Figure 1-2 As shown, the filling port 1020 of the existing tank box 1000 is arranged in the overflow box on the top of the tank box 1000. The filling port 1020 is usually sealed by a screw cap. A butterfly valve that can be opened and closed is provided inside the filling port 1020. The number of notches on the top circumference of the filling port 1020 is the same as that on the filling port, and the positions correspond to the notches, and a circular groove is provided on the lower outer side of the notch.

[0053] like Figure 3-6 As shown, the present invention provides a charging interface pipeline assembly, comprising:

[0054] The filling and fixing base plate 7100 provides a fixed support foundation for the entire interface module. It is usually a flat plate structure. When necessary, it can also be fixedly connected to other structures at the edge or have connection points for connecting to other structures at the edge. The filling and fixing base plate 7100 is an overall special-shaped structure.

[0055] The charging module connector 7200 is fixedly connected to the upper portion of the charging fixed base plate 7100 and can be connected to the gun module connector of the robot arm. The charging module connector 7200 and the gun module connector can adopt a common structure or a separately designed structure that can be positioned and connected to each other;

[0056] The charging rigid pipe joint module 7300 is vertically connected to the charging fixed base plate 7100, with its lower end located below the charging fixed base plate 7100. The upper portion of the charging rigid pipe joint module 7300 is used to connect to the charging pipeline, which is usually flexible enough to be moved by the robot arm. The lower portion of the charging rigid pipe joint module 7300 is used to connect to and seal the charging port 1020 of the tank container 1000. A control valve 7301 is installed in the charging rigid pipe joint module 7300.

[0057] The charging rotary module 7400 is sleeved onto the exterior of the charging rigid pipe joint module 7300 and is coaxially arranged with the charging rigid pipe joint module 7300 at the connection position. The bottom of the charging rotary module 7400 is provided with charging locking members 7450, the same number and corresponding positions as the notches in the charging port. The charging locking members 7450 can move downward along with the entire charging interface pipe assembly 7000, pass through the notches in the charging port 1020 of the tank container 1000, and be driven to rotate to form an axial lock with the charging port 1020 of the tank container 1000. The function of the charging rotary module 7400 is to form a lock with the charging port of the tank container 1000 to ensure a good seal between the charging rigid pipe joint module 7300 and the charging port 1020.

[0058] The charging sealing and locking module 7500 is located between the charging rigid pipe joint module 7300 and the charging rotating module 7400, and is sealed with the lower end of the charging rigid pipe joint module 7300 and the tank container's charging port. The charging sealing and locking module 7500 also has at least one charging locking plug 7523, located outside the charging outer sealing ring 7522 and arranged vertically downward. The charging locking plug 7523 is higher than the charging locking member 7450 and can be inserted into the notch of the tank container's charging port 1020. The charging sealing and locking module 7500 is located at the lower end of the charging rigid pipe joint module 7300 and can provide a transition seal, sealing the charging rigid pipe joint module while also being sealed with the charging port 1020.

[0059] The filling and opening cover unit 7600 is fixedly mounted on the filling fixed base plate 7100;

[0060] The front end of the flexible charging pipe 7700 is connected to the rigid charging pipe joint module 7300. The flexible charging pipe 7700 can move freely without restriction under the drive of the robotic arm, facilitating charging.

[0061] The charging control unit 7800 is connected to the rear end of the charging flexible pipeline 7700 and is used to provide power for charging. It can also blow air into the pipeline after charging is completed to quickly clean up the residual materials.

[0062] An external charging seal ring 7522 is provided on the outside of the charging sealing and locking module 7500. When the charging interface pipeline assembly 7000 is docked with the charging port of the tank container, a seal is formed between the external charging seal ring 7522 and the charging port 1020 of the tank container. The charging sealing and locking module 7500 is also provided with a step seal ring 7524, which is sealed with the step surface in the charging port of the tank container.

[0063] The charging rigid pipe joint module 7300 includes a rigid main pipe 7310 and a rigid side pipe 7320. The rigid main pipe is a straight pipe, and the control valve is located in the rigid main pipe 7310. A conical mouth structure adapted to the control valve 7301 is provided in the rigid main pipe 7310.

[0064] The charging rotary module 7400 includes:

[0065] The charging drive motor 7410 is fixedly connected to the upper portion of the charging fixed base plate 7100, and the output shaft of the charging drive motor 7410 passes through the charging fixed base plate 7100;

[0066] The charging drive gear 7420 is located below the charging fixed base plate 7100 and is fixedly connected to the output shaft of the charging drive motor 7410. The charging drive motor 7410 and the charging drive gear 7420 are separated on both sides of the charging fixed base plate 7100, thereby making the overall structural layout of the module more reasonable.

[0067] The charging gear 7430 is meshed with the charging drive gear 7420 for transmission, and the charging gear 7430 is coaxially connected to the outside of the rigid main pipe 7310. The charging gear 7430 is connected to the charging fixed base plate 7100 through a bearing so that the charging gear 7430 can rotate around the rigid main pipe 7310.

[0068] The charging rotary sleeve 7440 is fixedly connected to the charging gear 7430 and rotates under the drive of the charging gear 7430. The charging rotary sleeve 7440 is directly connected to the side of the charging gear 7430 through a flange, and the charging gear 7430 drives the charging rotary sleeve 7440 to rotate synchronously. The charging gear 7430 and the charging rotary sleeve 7440 are coaxially arranged with the rigid main pipe 7310, thereby driving the charging locking member 7450 to rotate coaxially around the charging port.

[0069] The charging locking pieces 7450 have the same number and corresponding positions as the notches on the charging port, are located on the bottom inner side of the charging rotating sleeve 7440 and are evenly distributed in the axial direction.

[0070] The filling locking member 7450 is a roller structure, and the diameter of the roller structure is smaller than the width of the annular groove outside the filling port of the tank box, so that the roller structure can pass through the gap of the filling port of the tank box along the axial direction and then rotate radially into the annular groove.

[0071] Filling, sealing and locking module 7500 includes:

[0072] The charging fixing ring 7510 is sleeved onto the exterior of the rigid main pipe 7310 and is fixedly connected to the charging fixing base plate 7100 via a flange. The charging fixing ring 7510 provides rigid support for the rigid main pipe 7310, thereby preventing the rigid main pipe 7310 from tilting and deforming when connected to the charging port, ensuring accurate docking and sealing between the rigid main pipe 7310 and the charging port 1020. The charging fixing ring 7510 and the rigid main pipe 7310 are coaxially arranged.

[0073] The charging connection ring 7520 is fixedly connected to the lower end of the charging fixed ring 7510. The inner wall of the charging connection ring 7520 is sealed with the outer wall of the rigid main pipe 7310 through the charging inner sealing ring 7521. The charging outer sealing ring 7522 is set on the outer wall of the charging connection ring 7520. The step sealing ring 7524 is set in the annular groove on the end face of the charging connection ring 7520 for sealing with the inner pipe mouth of the charging port. A step structure is provided at the position of the charging outer sealing ring 7522, and a storage space is provided at the step structure. The annular groove of the charging outer sealing ring 7522 is accommodated. When the charging outer sealing ring 7522 is sealed with the charging port, the charging outer sealing ring 7522 is compressed and restricted by the step structure, thereby achieving a better sealing effect; the charging locking plug 7523 is fixedly connected to the charging connecting ring 7520 and is located on the outside of the charging outer sealing ring 7522. The charging locking plug 7523 has a shape that is adapted to the notch of the charging port 1020, and the number of the charging locking plugs 7523 is also the same as the number of the notches, so that it can be inserted into all the notches.

[0074] The charging connecting ring 7520 and the charging fixing ring 7510 are connected in a detachable manner.

[0075] The charging fixing ring 7510 and the charging connecting ring 7520 are both coaxially arranged with the rigid main pipe 7310 .

[0076] The charging locking plug 7523 has the same number and corresponding position as the notches on the charging port, so that it can be inserted into the notches on the charging port to limit mutual rotation. A guiding relationship is formed between the charging locking plug 7523 and the notches on the charging port 1020, so that the charging locking plug 7523 can move axially along the notches.

[0077] The charging control unit 7800 includes a charging pump 7810 and an air blowing pump 7820 , wherein the charging pump 7810 and the air blowing pump 7820 are connected to the charging flexible pipeline 7700 through a three-way valve.

[0078] The charging interface pipeline assembly 7000 also includes a tail material collection unit 7900, which is connected to the charging fixed base plate 7100 and is used to collect the tail material at the outlet of the rigid main pipe 7310 after the charging is completed to avoid contamination.

[0079] The tail material collection unit 7900 includes a telescopic mechanism 7910, a rotating mechanism 7920, and a recovery box 7930. The telescopic mechanism 7910 is connected to the lower portion of the charging fixed base plate 7100 and can be extended and retracted downward. The rotating mechanism 7920 is connected to the bottom of the telescopic mechanism 7910 and moves vertically under the movement of the telescopic mechanism 7910 and can also rotate horizontally. The recovery box 7930 is connected to the rotating mechanism 7920 and can be rotated to the bottom of the rigid main pipe 7310 under the movement of the rotating mechanism 7920. The tail material collection unit 7900 effectively ensures that after charging is completed, residual materials will not contaminate the equipment or the environment.

[0080] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
