This utility model has a novel structure. The cooperation between the fixed frame, the mounting strip, and the mounting groove ensures accurate installation and positioning of the station control module. The rigid locking structure of the L-shaped slider prevents the module from loosening or shifting during equipment operation. During maintenance, there is no need to completely disassemble the station control cabinet or module mounting plate. Only the pressing block needs to be pressed to unlock a single station control module, realizing independent disassembly and assembly of a single module. This avoids the interference of traditional whole disassembly on other normal modules, shortens maintenance time, and reduces the difficulty and labor intensity of maintenance personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LNG refueling station control device, comprising a control cabinet, a base fixedly connected to the bottom of the control cabinet, a module mounting plate fixedly installed on the front side of the control cabinet, a control module disposed in each of the multiple slots on the module mounting plate, a fixing frame fixedly connected to the periphery of each of the multiple slots on the module mounting plate to cooperate with the control module, an installation component disposed between the control module and the fixing frame, a display panel and an emergency stop button fixedly installed on the front side of the control cabinet, and a control button fixedly connected to the front side of the control cabinet.

[0005] Furthermore, the front side of the station control module is fixedly connected to an installation panel located on the inner wall of the fixed frame, and both sides of the station control module are fixedly connected to installation strips. The inner walls of the multiple empty slots on the module installation plate are provided with installation grooves that slide with the installation strips.

[0006] Furthermore, the back of the module mounting plate is fixedly connected with multiple sets of limiting frames corresponding to the mounting slots on both sides. The inner walls of the two opposite sides of the fixing frames are provided with fixing slots, and the inner walls of the fixing slots are provided with through holes extending outward.

[0007] Furthermore, the mounting assembly includes a pressing post that slides within a through hole, a pressing block that is fixedly connected to the outer end of the pressing post, a spring that is fixedly connected between the inner side of the pressing block and the outer wall of the fixing frame, and an abutment block that slides within a fixing groove that is fixedly connected to the inner end of the pressing post.

[0008] Furthermore, the mounting strip has a through groove that communicates with the fixing groove. An L-shaped slider is slidably fitted in the through groove and the fixing groove. The lateral side of the L-shaped slider is slidably fitted in the fixing groove and overlaps with the abutment block. The longitudinal side of the L-shaped slider is slidably fitted in the through groove.

[0009] Furthermore, the station control module has externally rotating limit frames on both sides, and rotating shafts are fixedly connected to the outer sides of both sides of the station control module. The two side plates of the limit frames are provided with connecting grooves that rotate with the rotating shafts. The station control module is located between the two side plates of the limit frames.

[0010] Furthermore, the ends of the two side plates of the limiting frame facing the mounting strips on both sides of the station control module are semi-circular and corresponding to them. The semi-circular sides of the two side plates of the limiting frame are provided with spiral arc grooves.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 7 This utility model provides a technical solution: an LNG refueling station control device, including a control cabinet 1, a base 2 fixedly connected to the bottom of the control cabinet 1, a module mounting plate 3 fixedly installed on the front side of the control cabinet 1, a control module 5 disposed in multiple slots on the module mounting plate 3, a fixing frame 4 fixedly connected to the periphery of the multiple slots on the module mounting plate 3 to cooperate with the control module 5, an installation component 6 disposed between the control module 5 and the fixing frame 4, a display panel 7 and an emergency stop button 8 fixedly installed on the front side of the control cabinet 1, and a control button 9 fixedly connected to the front side of the control cabinet 1.

[0025] In this embodiment, the station control module 5 is fixedly connected to the front side of the mounting panel 10 located on the inner wall of the fixed frame 4. The station control module 5 is fixedly connected to both sides of the mounting strip 11. The inner walls of the multiple slots on the module mounting plate 3 are provided with mounting grooves 12 that slide with the mounting strips 11. The back of the module mounting plate 3 is fixedly connected to multiple sets of limiting frames 13 corresponding to the mounting grooves 12 on both sides. The inner walls of the opposite sides of the fixed frame 4 are provided with fixing grooves 14. The inner walls of the fixing grooves 14 are provided with through holes 15 extending outward. The mounting component 6 includes a pressing post 601 that slides in the through hole 15. The outer end of the pressing post 601 is fixedly connected to a pressing block 602. The inner side of the pressing block 602 is fixedly connected to the outer wall of the fixed frame 4 with a spring 603. The inner end of the pressing post 601 is fixedly connected to an abutment block 604 that slides in the fixing groove 14.

[0026] Specifically, the station control device uses the station control cabinet 1 as the main frame, and the bottom is stably supported by the base 2. The front integrated module mounting plate 3 serves as the mounting carrier for the station control module 5. The station control module 5 is initially positioned by sliding the mounting strips 11 on both sides with the mounting grooves 12 on the inner wall of the empty groove of the module mounting plate 3. At the same time, the fixing frame 4 around the empty groove of the module mounting plate 3 provides peripheral limit for the station control module 5 to ensure accurate module installation position.

[0027] In this embodiment, the mounting strip 11 has a through groove 16 communicating with the fixing groove 14. An L-shaped slider 605 is slidably fitted in the through groove 16 and the fixing groove 14. The lateral side of the L-shaped slider 605 is slidably fitted in the fixing groove 14 and overlaps with the abutment block 604. The longitudinal side of the L-shaped slider 605 is slidably fitted in the through groove 16. The two sides of the station control module 5 are externally fitted with limit frames 606. Rotating shafts 608 are fixedly connected to the outer sides of both sides of the station control module 5. The two side plates of the limit frames 606 are provided with connecting grooves 607 that are rotatably fitted with the rotating shafts 608. The station control module 5 Located between the two side plates of the limiting frame 606, the ends of the two side plates of the limiting frame 606 facing the mounting strips 11 on both sides of the station control module 5 are semi-circular and corresponding to them. The semi-circular circumference of the two side plates of the limiting frame 606 is provided with a spiral arc groove 609. One side of the longitudinal edge of the L-shaped slider 605 is fixedly connected to a connecting post 610 that slides with the inner wall of the arc groove 609. The opposite sides of the two side plates of the limiting frame 606 are provided with grooves 611 located on the same central axis as the connecting grooves 607. Torsion springs 612 are fixedly connected between the outer sides of the two sides of the station control module 5 and the inner walls of the grooves 611 on the two side plates of the limiting frame 606.

[0028] Specifically, under normal conditions, the torsion spring 612 drives the limiting frame 606 to rotate around the rotating shaft 608 through elastic force. The spiral arc grooves 609 on both side plates drive the L-shaped slider 605 to slide through the connecting column 610. The lateral side of the L-shaped slider 605 is embedded in the fixing groove 14 of the fixing frame 4, and the longitudinal side is limited in the through groove 16 of the mounting strip 11, forming a rigid lock of "fixing frame 4 - mounting strip 11 - L-shaped slider 605", which firmly fixes the station control module 5 on the module mounting plate 3. When When the station control module 5 needs to be disassembled, press the pressing block 602 on the outside of the fixing frame 4. The pressing column 601 pushes the abutment block 604 to slide in the fixing groove 14. The abutment block 604 pushes the lateral side of the L-shaped slider 605, causing it to disengage from the fixing groove 14. At the same time, the L-shaped slider 605 drives the limiting frame 606 to rotate against the elastic force of the torsion spring 612 through the connecting column 610 until the longitudinal side of the L-shaped slider 605 is completely retracted into the through groove 16. At this time, the station control module 5 can be slid outward along the mounting groove 12 and taken out.

[0029] When using the device, during the assembly stage, first fix the base 2 to the bottom of the station control cabinet 1 to ensure overall stability, then fix the module mounting plate 3 to the front of the station control cabinet 1, and then assemble the fixing frame 4 around each empty slot of the module mounting plate 3; when installing the station control module 5, align the mounting strips 11 on both sides of the module with the mounting grooves 12 on the inner wall of the empty slot, and slide them inward along the mounting grooves 12 until the mounting panel 10 on the front of the station control module 5 fits against the inner wall of the fixing frame 4. At this time, the torsion spring 612 drives the limit frame 606 to rotate around the rotating shaft 608 by its own elastic force. The spiral arc grooves 609 on both sides of the limit frame 606 drive the L-shaped slider 605 to move through the connecting column 610, so that the lateral side of the L-shaped slider 605 slides into the fixing groove 14 of the fixing frame 4 and the longitudinal side is limited in the through groove 16 of the mounting strip 11, forming a multi-directional locking, completing the assembly of a single station control module 5. The display panel 7 displays the operating parameters of the LNG refueling station in real time, and the staff can realize the operation through the control button 9. The system includes standard controls such as gas refueling start / stop and operating mode switching. In case of a sudden malfunction, pressing the emergency stop button 8 will immediately trigger an emergency shutdown of the equipment to prevent the danger from escalating. If module disassembly and maintenance are required, during disassembly, the operator presses the pressing block 602 on the outside of the fixing frame 4. The pressing column 601 pushes the abutment block 604 to slide in the fixing groove 14. The abutment block 604 pushes the lateral side of the L-shaped slider 605 out of the fixing groove 14. At the same time, the L-shaped slider 605 drives the limit frame 606 to rotate against the elastic force of the torsion spring 612 through the connecting column 610 until the longitudinal side of the L-shaped slider 605 is completely retracted into the through groove 16. At this time, the station control module 5 can be removed for inspection or replacement by sliding it outward along the mounting groove 12. After maintenance, the station control module 5 is slid into the mounting groove 12 in the same way as the assembly stage. The pressing block 602 is released, and the torsion spring 612 resets and drives the limit frame 606 to rotate, causing the L-shaped slider 605 to re-embed into the fixing groove 14 and the through groove 16, completing the module reset installation and restoring the device operation.
