[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0024] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The automatic drive quick connector shown includes a connecting drop pipe 1 and a tank truck side valve body 5 for connecting to a tank truck. A break valve 2 is fixedly installed at the end of the connecting drop pipe 1. A motor 3 is fixedly installed on the outside of the connecting drop pipe 1 through a lateral bracket. The connecting end of the break valve 2 is equipped with a rotary valve body 4 for connecting to the tank truck side valve body 5. A lateral valve shell 6 is equipped on the outside of the rotary valve body 4. A large gear 7 is sleeved and fixed on the outside of the rotary valve body 4. A small gear 8 meshing with the large gear 7 is provided on the upper end of the lateral valve shell 6. A reducer 9 is installed at the output end of the motor 3. The output end of the reducer 9 is axially driven with the small gear 8 through a coupling 10. A camshaft 11 is provided inside the rotary valve body 4. The camshaft 11 is connected to the main valve core 13 through a connecting plate 12. A tank truck side valve core 14 is provided inside the tank truck side valve body 5.

[0026] In order to improve the elastic reset capability, a compression spring 15 is sleeved on the valve core 14 on the tank truck side.

[0027] In order to improve the guiding performance, four guide plates 16 are fixedly mounted on the outer side of the rotary valve body 4 .

[0028] The male connector on the tank car side is inserted into the female connector on the loading arm side for connection. Four guide plates 16 are provided on the rotary valve body 4 to play a guiding role, which can make the connection more accurate and convenient, and can effectively prevent other workpieces from being damaged.

[0029] In order to facilitate control, a proximity switch 17 is installed on the side wall of the connecting end of the rotary valve body 4.

[0030] A proximity switch 17 is installed on the rotary valve body. When the rotary valve body 4 rotates, the main valve core 13 opens, and the proximity switch 17 senses that the open position has been reached, and the rotary valve body 4 stops rotating. The proximity switch 17 can effectively feedback whether the valve core is fully open.

[0031] In order to facilitate control, a path groove 18 is provided on the rotary valve body 4 to match the camshaft 11 .

[0032] In order to effectively prevent the fluid from freezing due to low temperature and causing transmission failure, the outer side of the rotary valve body 4 is fixedly connected to the large gear 7 through the valve body connector 19 and the cold insulation gasket 20.

[0033] Working principle:

[0034] Motor 3 drives the gears to rotate; large gear 7 is connected to the rotary valve body 4, driving the rotary valve body 4 to rotate. Main valve core 13 is connected to the connecting plate of camshaft 11 via a pin. A path groove is provided in the rotary valve body 4, and camshaft 11 moves along path groove 18. Main valve core 13 opens. Similarly, reverse rotation of the rotary valve body 4 closes main valve core 13. This motor 3 drives the dry valve mechanism, automatically controlling the opening and closing of the dry valve, facilitating operation, saving time, and improving efficiency.

[0035] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
