[0025] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] Figures 1-6 This is an embodiment of the present invention. The existing liquid replenishing device has low liquid compatibility. Some liquids can easily cause serious damage to metals and cause damage to the device. The process flexibility of the device itself is poor. The lack of an alarm system causes the device to stagnate due to the lack of liquid, which further causes the entire project to stagnate, resulting in delays in work time. Based on the existing problems described above, this solution proposes an automatic liquid adding device, which adds a liquid level sensor, a pressure sensor and a temperature sensor 7 to the liquid adding barrel body 1 to ensure that the various numerical changes of the liquid in the barrel can be monitored at all times, and an automatic liquid replenishing structure 2 is set on the liquid adding barrel body 1, which can replenish liquid to the inside without stopping the operation after the liquid level in the liquid adding barrel body 1 is reduced, thereby improving the liquid replenishment effect.

[0028] The automatic liquid adding device described specifically includes a liquid adding barrel body 1 for holding liquid, an automatic liquid replenishing structure 2 is provided on the liquid adding barrel body 1, and a transport trolley 3 is provided at the lower end of the liquid adding barrel body 1 for assisting the liquid adding barrel body 1 to move to a preset position.

[0029] A liquid adding port is provided on the liquid adding barrel body 1, and a feeding sleeve 4 is welded on the liquid adding port. A quick-install component 5 for adding liquid into the liquid adding barrel body 1 is installed on the feeding sleeve 4. The feeding sleeve 4 is T-shaped and a sealing plate 12 is installed on the feeding sleeve 4. An inner groove is provided at the upper end of the feeding sleeve 4, and a filling ring filled in the inner groove is installed at the bottom of the sealing plate 12 to reduce the overflow channel between the sealing plate 12 and the feeding sleeve 4. The quick-release assembly 5 is arranged on the closing plate 12. The quick-release assembly 5 includes a left-right symmetrical articulated arm 51 and a connecting plate 52 installed between the two articulated arms 51. A connecting rod 53 is installed between the two articulated arms 51 facing away from the connecting plate 52. A plug-in interface 54 is provided on each of the two articulated arms 51. The connecting rod 53 is rotatably connected to a single cross-connection arm and extends to the plug-in interface 54 of the other articulated arm 51. An inner recessed groove 55 adapted to the protruding edge structure of the feeding sleeve 4 is provided on the interior of the articulated arm 51. The width of the inner recessed groove 55 is equal to the sum of the thicknesses of the edge structures of the closing plate 12 and the feeding sleeve 4. When the two articulated arms 51 are affected by the connecting rod 53 and the distance between them is limited, the distance between the two articulated arms 51 is adapted to the diameter of the closing plate 12. On the other hand, the width of the inner recessed groove 55 limits the gap between the closing plate 12 and the feeding sleeve 4, thereby increasing the sealing degree between the closing plate 12 and the feeding sleeve 4. Liquid is added by opening the quick-release assembly 54 until the liquid level sensor reads between 95% and 100%, which indicates the device is full. Once liquid is added, the filling sleeve 4 is sealed with the sealing plate 12, and the filling barrel 1 is ready for use. The pressure-reducing valve 22 on the trolley then connects to the CDA air line and the self-sealing quick-change connector 21 on the automatic filling device to replenish the pressure in the barrel.

[0030] The automatic refill mechanism 2 includes a self-sealing quick-change connector 21 mounted on the liquid-filling barrel body 1, and a pressure-reducing valve 22 connected thereto for replenishing pressure within the liquid-filling barrel body 1. A connecting pipe assembly 23 is connected to the self-sealing quick-change connector 21. The transport trolley 3 is equipped with an electronic control device 13 for connecting the automatic refill mechanism 2 and the manual refill circuit. A pressure relief valve 6 is installed on the liquid-filling barrel body 1. This valve 62 automatically pops out when the pressure exceeds the customer's set pressure (the default setting is 0.5 MPa, with a maximum limit of 1.0 MPa). This improves the safety of the equipment and prevents excessive intake pressure from damaging the automatic refill mechanism. A temperature sensor 7 is installed at one end of the pressure relief valve 6 to monitor the internal temperature of the liquid filling barrel 1. A motorized ball valve 9 is mounted on the self-sealing quick-change connector 21 to establish and close access to the liquid filling barrel 1. The required volume of liquid is set on the display on the cart. Clicking "Fill" automatically opens the motorized ball valve 9 to replenish the device. During the replenishment process, a liquid level sensor transmits a signal to the central control system. When the liquid level in the automatic refill system drops to the preset refill volume, the system automatically closes the motorized ball valve 9, stopping the replenishment process. When the liquid level sensor detects a drop below 10%, an alarm is triggered, alerting the operator to refill the device. A refill tube 10 is attached to the self-sealing quick-change connector 21, extending into the liquid filling barrel 1. A manual valve 11 is mounted on the extension path of the connecting tube assembly 23. To manually replenish liquid using the automatic refill system, the motorized ball valve 9 is opened, the manual valve 11 is closed, and the manual valve 11 is manually operated to refill the device.

[0031] The metal parts installed on the barrel body 1 of the liquid adding barrel are all made of SUS316 stainless steel. Except for the barrel body 1 and the necessary welding joints, all equipment are connected by threaded connection, which avoids the inability to replace parts due to aging or damage of the equipment, thereby causing the entire equipment to be scrapped and facilitates disassembly. The fixed trolley is welded with multiple square tubes and has good shock absorption performance. At the same time, it can carry more than 200KG of cargo. There is a certain space on the body to install other equipment, which is convenient for the modification of the device.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0033] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
