Description

Technical Field

[0001] This utility model relates to the field of hydraulic control technology, specifically an output protection type solenoid valve driver. Background Technology

[0002] In recent years, with the vigorous promotion of national intelligent mine construction, the application of underground hydraulic power systems in coal mines has become increasingly widespread. These include hydraulic cylinders supporting hydraulic supports, push cylinders for pulling supports, cylinders for pushing and pulling scraper conveyors, and push cylinders at the treadle, all of which rely on the precise control of valve assemblies. As the core equipment for controlling valve assemblies, solenoid valve actuators play the role of the final executor in intelligent mines, and their stability and reliability are crucial. However, the solenoid valve actuators currently on the market have the following main problems:

[0003] 1. Design Limitations: Existing solenoid valve actuators have numerous interfaces, and the number of functions offered by different manufacturers varies significantly (e.g., 24 functions or 16 functions). Due to the high protection requirements of these devices, they often employ a potted structure. This design makes repair difficult, or even impossible, once a fault occurs. Furthermore, because they rely on a single main power supply, a fault in one circuit can affect other circuits, posing a serious threat to safety.

[0004] 2. Difficulty in connection and diagnosis: Due to the numerous functions of solenoid valve actuators, extensive wiring work is required when matching them in a series. This not only increases the difficulty of construction but also increases the potential points of failure. Moreover, current solenoid valve actuators lack self-diagnostic functions, making it difficult to detect and locate faults in a timely manner, which brings great inconvenience to maintenance and management.

[0026] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0027] Please see Figure 1 , Figure 2 , Figure 3 ,

[0028] In this embodiment of the utility model, an output protection type solenoid valve driver includes a housing 1 and a solenoid valve drive plate (not shown), the solenoid valve drive plate being fixedly disposed inside the housing;

[0029] The outer casing 1 includes a bottom shell 11 and a top cover 12. The top cover 12 is detachably and fixedly mounted on the upper side of the bottom shell 11. U-shaped grooves 13 are symmetrically arranged on both sides of the bottom shell 11. The openings of the U-shaped grooves 13 face forward. Fixed mounting holes 14 are provided at the bottom and rear of the U-shaped grooves 13. The top cover 12 is provided with a cable inlet 15, a cable outlet 16, and an airtight opening 17.

[0030] It also includes a driver protection plate 2, which is fixedly installed in a U-shaped groove 13 on one side of the bottom housing 11. Multiple cable output ports 16 are provided and evenly distributed. The top cover 12 is detachably fixed to the upper side of the bottom housing 11 by fasteners 18.

[0031] The solenoid valve drive board contains only a microcontroller and a power management module, with the power management module electrically connected to the microcontroller module. The driver protection board 2 contains a circuit protection module, which is connected to the microcontroller.

[0032] The outer shell of this utility model is detachably connected, and the electrical connection channels are all realized through the cover plate 12, which facilitates maintenance. The bottom shell 11 has symmetrically arranged U-shaped grooves 13 and fixing mounting holes 14 on both sides, which facilitates installation. The driver protection plate 2 not only protects the solenoid valve drive plate, but also, since the driver protection plate 2 is set in the U-shaped groove 13, it is easy to maintain and repair, and is not easily damaged by squeezing or collision.

[0033] This utility model's solenoid valve drive board can integrate indicator lights and connector sockets for driving and controlling multiple solenoid valves. The power management module can be designed with multiple independent power supply circuits to ensure that a fault in any circuit will not affect other circuits. The circuit protection module can integrate overvoltage, overcurrent, and short-circuit protection circuits, monitoring and cutting off abnormal circuits in real time to prevent damage to the load. It supports remote program updates via remote client software, improving the maintainability and flexibility of the equipment. The MCU periodically polls and detects the voltage and current information of each functional circuit and reports it to the remote client in real time. When a fault is detected, a fault report is proactively pushed for quick location and handling. When fault information is detected, the driver will proactively push a fault report, enabling administrators to quickly and accurately locate the port of the faulty functional circuit, thus significantly improving the efficiency of problem detection and handling. This proactive fault handling method, compared to the traditional passive detection method, greatly improves the safety and reliability of field applications. Remote program updates improve equipment maintainability and also increase the work efficiency of field maintenance personnel.

[0034] This invention is also particularly suitable for large-scale application along fully mechanized mining faces (the number of complete sets is expected to reach around 200). The actuator can adopt two working modes—dormant mode and working mode—to meet the needs of hydraulic supports for solenoid valve actuators in different operating scenarios.

[0035] Sleep Mode: When the hydraulic support is far from the coal mining machine (more than 50 supports away), i.e., when the hydraulic support is not in operation, the solenoid valve actuator will automatically enter sleep mode. In this mode, the actuator only responds to the communication handshake query of the support controller, which greatly reduces energy consumption. The power consumption in sleep mode can be controlled to an extremely low level of less than 500μA.

[0036] Operating Mode: Once the hydraulic support approaches the coal mining machine (within 50 supports), the solenoid valve actuator will quickly switch to the operating mode. In this mode, the actuator not only maintains communication with the support controller, but also periodically and proactively reports the status of each circuit to ensure timely and accurate operation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
