[0002] Coal mines have underground pipeline systems, including water supply pipelines and compressed air pipelines, each equipped with control valve assemblies. The control valve assemblies in the water supply pipelines can spray air into the ventilation tunnels, while the control valve assemblies in the compressed air pipelines control whether compressed air is discharged. However, ensuring the normal operation of these control valve assemblies requires a stable power supply. Due to the complex environment of underground coal mines, laying cables and transformers to power the control valve assemblies is costly; using battery power cannot guarantee power stability and requires timely battery maintenance and replacement, making long-term continuous operation difficult. Summary of the Invention

[0006] In one possible implementation, the wind power generation unit includes a wind guide shroud and a first mechanical output component.

The switching transmission assembly includes a second transmission component, which is disposed between the second mechanical output component and the first transmission component. The input end of the second transmission component is mechanically connected to the second mechanical output component. The second transmission component can drive the generator to generate electricity when the rotational speed reaches a second preset parameter.

[0008] In one possible implementation, the compressed air duct passes through the air guide shroud, such that a portion of the compressed air duct is contained within the air guide shroud. The pneumatic power generation mechanism includes a third mechanical output component, which is disposed in the section of the compressed air pipeline inside the air guide shroud.

[0024] Please refer to Figures 1 to 3 This application provides a self-generated remote control valve assembly 1, which is particularly suitable for underground coal mine environments. The underground coal mine environment includes a ventilation roadway A1 and a pipeline system, which includes a water supply pipeline A2 and a compressed air pipeline A3. The self-generated remote control valve assembly 1 includes a remote control valve assembly 10, which is used to control the on / off state of the pipeline system in the underground coal mine.

[0025] The self-generated remote control valve assembly 1 includes an energy storage module 20. The energy storage module 20 is electrically connected to the remote control valve assembly 10.

[0026] The self-generated remote control valve group 1 includes a co-generation module 30, which is used to supply power to the energy storage module 20.

[0027] The collaborative power generation module 30 includes a wind power generation unit 301. The wind power generation unit 301 is installed in the ventilation roadway A1 underground in the coal mine, and is used to convert wind energy in the ventilation roadway A1 into electrical energy.

[0028] The collaborative power generation module 30 includes a hydraulic power generation unit 302. Installed in the water supply pipeline A2 underground in the coal mine, the hydraulic power generation unit 302 is used to convert the kinetic energy of the fluid in the water supply pipeline A2 into electrical energy.

[0029] The collaborative power generation module 30 includes a pneumatic power generation unit 303. Installed in the compressed air pipeline A3 underground in the coal mine, the pneumatic power generation unit 303 is used to convert the compressed pressure energy into electrical energy.

[0030] The self-generated remote control valve group 1 includes a controller 40. The controller 40 is communicatively connected to the remote control valve group 10 and the collaborative power generation module 30. The controller 40 can control the pneumatic power generation unit 303 to supply power to the energy storage module 20 based on the mechanical output speed of the wind power generation unit 301, the mechanical output speed of the hydraulic power generation unit 302, and the voltage parameters in the energy storage module 20.

[0031] The self-generated remote control valve group 1 includes a switching transmission assembly 305. The switching transmission assembly 305 is communicatively connected to the controller 40, and the input terminals of the switching transmission assembly 305 are respectively connected to the wind power generation unit 301, the hydraulic power generation unit 302, and the pneumatic power generation unit 303.

[0032] Specifically, the remote control valve group 10 is installed in the pipeline system underground in the coal mine. Its working status is controlled by the controller 40, and it is powered by the energy storage module 20, which is charged by the co-generation module 30. The co-generation module 30 can be divided into three parts: a wind power generation unit 301, a hydraulic power generation unit 302, and a pneumatic power generation unit 303. The wind power generation unit 301 is installed in the ventilation roadway A1, while the hydraulic power generation unit 302 and the pneumatic power generation unit 303 are installed in the water supply pipeline A2 and the compressed air pipeline A3 in the pipeline system, respectively. The wind power generation unit 301, hydraulic power generation unit 302, pneumatic power generation unit 303, generator 304, and switching transmission assembly 305 in the collaborative power generation module 30 are all coaxially connected. The switching transmission assembly 305 is disposed between the wind power generation unit 301, hydraulic power generation unit 302, pneumatic power generation unit 303 and generator 304. The input end of the switching transmission assembly 305 is connected to the mechanical output components in the wind power generation unit 301, hydraulic power generation unit 302 and pneumatic power generation unit 303.

[0033] The abundant wind resources in ventilation tunnel A1 can drive the wind power generation unit 301 to work and generate electricity. To ensure that the collaborative power generation module 30 can stably supply power to the energy storage module 20, the hydraulic power generation unit 302 and the pneumatic power generation unit 303 are used as backup power generation methods. When the wind resources in ventilation tunnel A1 are insufficient and the water supply pipeline A2 is open, the hydraulic power generation unit 302 can be activated first to supply power to the energy storage module 20. When the remote control valve group 10 activates the spray mode, the liquid flow rate in the water supply pipeline A2 will decrease, resulting in a decrease in the amount of electricity converted by the hydraulic power generation unit 302. At this time, the wind power generation unit 301 can be connected again, so that the wind power generation unit 301 and the hydraulic power generation unit 302 work together, thereby increasing the power generation of the collaborative power generation module 30. If the wind power generation unit 301 and the hydraulic power generation unit 302 cannot work normally due to environmental conditions, the controller 40 can control the pneumatic power generation unit 303 to start working in order to supply power to the energy storage module 20, thereby ensuring the normal operation of the remote control valve group 10.

[0034] Thus, the self-generated remote control valve group 1 provided in this application embodiment can fully utilize the wind energy in the ventilation roadway A1 of the coal mine, as well as the fluid kinetic energy and pressure energy in the water supply pipeline A2 and the compressed air pipeline A3, to form a multi-energy collaborative power supply mode. This not only realizes the self-powering of the remote control valve group 10 and reduces the dependence on external power sources, but also regulates the collaborative power generation module 30 through the controller 40. When the wind power is insufficient or the water supply pressure changes, the power supply mode is automatically switched or combined, which improves the reliability and stability of the power supply. This ensures the continuous and reliable operation of the remote control valve group 10 in the complex underground environment and enhances the autonomy and safety of the control of the underground pipeline system in the coal mine.

[0035] In some embodiments, the cooperative power generation module 30 further includes a generator 304. The generator 304 is electrically connected to the remote control valve group 10, and the output terminal of the switching transmission assembly 305 is connected to the generator 304.

[0036] The wind power generation unit 301 and the hydraulic power generation unit 302 can be located on one side of the generator 304 to facilitate their coordinated operation, while the pneumatic power generation unit 303 can be located on the other side of the generator 304, allowing the controller 40 to more precisely control the pneumatic power generation unit 303. The output end of the switching transmission component 305 is connected to the generator 304, enabling selective access of the power generation unit based on the rotational speed of the mechanical output components. This ensures a more stable power supply to the collaborative power generation module 30 while also providing some protection for the generator 304.

[0037] In the above embodiments, the generator 304, switching transmission assembly 305, wind power generation unit 301, hydraulic power generation unit 302 and pneumatic power generation unit 303 are mechanically coupled coaxially by the integrated collaborative power generation module 30, which improves the compactness of the collaborative power generation module 30 structure. The switching transmission assembly 305 can make the power generation process more stable and the power supply to the remote control valve group 10 more continuous and reliable. At the same time, it can also effectively buffer the impact of sudden load on the generator 304, improve the impact resistance of the collaborative power generation module 30, and thus improve the overall durability and operational safety of the self-generated remote control valve group 1.

[0038] In some embodiments, such as Figure 2 As shown, the wind power generation unit 301 includes a wind guide shroud 3011 and a first mechanical output component 3012. The wind guide shroud 3011 is disposed in the ventilation channel A1, and the generator 304 is disposed inside the wind guide shroud 3011; the first mechanical output component 3012 is disposed in the wind guide shroud 3011, and the first mechanical output component 3012 can be driven by the wind energy passing through the wind guide shroud 3011 in the ventilation channel A1 and convert the wind energy into kinetic energy.

[0039] The switching transmission assembly 305 includes a first transmission member 3051. The first transmission member 3051 is disposed between the first mechanical output component 3012 and the generator 304. The input end of the first transmission member 3051 is switchably connected to the first mechanical output component 3012. The first transmission member 3051 can be connected to the engine for transmission when the speed reaches a first preset parameter.

[0040] Because the space in the underground ventilation roadway A1 of the coal mine is relatively large, directly placing the first mechanical output component 3012 in the ventilation roadway A1 may result in uneven wind distribution, affecting the power generation effect of the wind power generation unit 301. However, by installing a wind guide hood 3011 in the underground ventilation roadway A1, the wind force passing through the wind guide hood 3011 can be more concentrated, thereby improving the driving effect of the wind force in the ventilation roadway A1 on the first mechanical output component 3012. The wind speed detection element in the parameter acquisition module can be installed in the wind guide hood 3011.

[0041] Accordingly, a first transmission component 3051 is provided between the first mechanical output component 3012 and the generator 304. The first mechanical output component 3012 can be a wind turbine impeller, and the first transmission component 3051 can be an overrunning clutch. The overrunning clutch can automatically engage with the generator 304 when a certain speed is reached, and automatically disengage from the generator 304 when the speed is below a certain speed. Therefore, the first preset parameter is the speed at which the first transmission component 3051 can automatically engage with the generator 304. When the first mechanical output component 3012 is driven to rotate by the wind in the ventilation duct A1, the first transmission component 3051 can rotate accordingly. When the speed of the first mechanical output component 3012 reaches the first preset parameter, the first transmission component 3051 can automatically engage with the generator 304, thereby achieving the purpose of utilizing the wind power generation unit 301.

[0042] In the above embodiment, by setting the wind guide hood 3011 to concentrate the wind force in the ventilation tunnel A1, the driving efficiency of the first mechanical output component 3012 is improved, thereby enhancing the wind energy conversion effect. Using an overrunning clutch as the first transmission component 3051, automatic engagement and transmission are achieved when the wind force reaches the first preset parameter. This not only enables the wind power generation unit 301 to operate stably in the high-efficiency range but also avoids dragging or impacting the generator 304 at low wind speeds. Thus, the power generation performance of the self-generating remote control valve group 1 is optimized under the premise of a compact structure, enhancing the adaptability of the self-generating remote control valve group 1 to fluctuating downhole wind conditions and the reliability of stable operation.

[0043] In some embodiments, the water supply pipe A2 passes through the air guide shroud 3011 so that a portion of the water supply pipe A2 is located within the air guide shroud 3011.

[0044] The hydraulic power generation unit 302 includes a second mechanical output component 3021. The second mechanical output component 3021 is disposed in the pipe section of the water supply pipe A2 inside the air guide shroud 3011. The second mechanical output component 3021 can be driven by the water flow in the water supply pipe A2 to convert the mechanical energy contained in the water flow into kinetic energy.

[0045] The switching transmission assembly 305 includes a second transmission member 3052. The second transmission member 3052 is disposed between the second mechanical output component 3021 and the first transmission member 3051. The input end of the second transmission member 3052 is mechanically connected to the second mechanical output component 3021. The second transmission member 3052 can drive the generator 304 to generate electricity when the rotational speed reaches a second preset parameter.

[0046] To improve the power generation efficiency of the wind power generation unit 301, the length of the air guide shroud 3011 is appropriately extended, provided that the conditions in the ventilation duct A1 permit. Since the hydraulic power generation unit 302 is coaxially arranged with the wind power generation unit 301 and the generator 304, and the hydraulic power generation unit 302 needs to be installed in the water supply pipeline A2, in order to ensure the compactness of the overall structure of the collaborative power generation module 30, a section of the water supply pipeline A2 can be inserted into the air guide shroud 3011, thereby ensuring the coaxiality between each power generation unit, the switching transmission component 305, and the generator 304.

[0047] For example, the second mechanical output component 3021 can be a hydraulic turbine, and the second transmission component 3052 can be a centrifugal clutch. When the wind speed flowing through the air guide shroud 3011 in the ventilation tunnel A1 is low, causing the rotational speed of the first transmission component 3051 to be lower than the first preset parameter and thus unable to connect to the generator 304, and the water flow in the water supply pipe A2 can drive the second mechanical output component 3021 to rotate and drive the second transmission component 3052 to reach the second preset parameter, based on the characteristics of the centrifugal clutch, the second transmission component 3052 can automatically engage with the generator 304, thereby activating the hydraulic power generation unit 302 to generate electricity.

[0048] In the above embodiment, the water supply pipe A2 is installed inside the air guide shroud 3011, which cleverly realizes the compact coaxial layout of the hydraulic power generation unit 302, the wind power generation unit 301, and the generator 304 in physical space. This not only optimizes the overall structure of the collaborative power generation module 30 and saves the installation space of the ventilation roadway A1 in the underground coal mine, but also realizes the speed-triggered automatic engagement of the hydraulic power generation unit 302 with the help of the second transmission component 3052. This allows for rapid and autonomous switching or supplementary power generation when the wind power is insufficient, ensuring the continuity and efficiency of the power supply of the collaborative power generation module 30. In turn, it enhances the self-generating remote control valve group 1's adaptability and overall reliability to complex working conditions in the underground coal mine.

[0049] In some embodiments, the compressed air duct A3 passes through the air guide shroud 3011 so that a portion of the compressed air duct A3 is located within the air guide shroud 3011.

[0050] The pneumatic generator 304 includes a third mechanical output component 3031. The third mechanical output component 3031 is disposed in a section of the compressed air duct A3 inside the air guide shroud 3011. The third mechanical output component 3031 can be driven by compressed air in the compressed air duct A3 to convert the mechanical energy contained in the compressed air into kinetic energy.

[0051] The switching transmission assembly 305 includes a third transmission component 3053. The third transmission component 3053 is disposed between the third mechanical output component 3031 and the generator 304. The input end of the third transmission component 3053 is mechanically connected to the third mechanical output component 3031. The controller 40 can control the third transmission component 3053 to connect with the generator 304 to supply electrical energy to the energy storage module 20 if the energy storage module 20 does not meet the preset conditions.

[0052] As described in the above embodiments, in order to improve the compactness of the structure of the collaborative power generation module 30 and meet the coaxiality requirements between each power generation unit, generator 304, and switching transmission assembly 305, a portion of the compressed air pipeline A3 can be inserted through the air guide shroud 3011. The third mechanical output component 3031 can be a pneumatic turbine, and the third transmission component 3053 can be an electromagnetic clutch. When the speeds of the first transmission component 3051 and the second transmission component 3052 are low, the controller 40 can control the third transmission component 3053 to connect to the generator 304, thereby connecting the pneumatic power generation unit 303 to the generator 304 to supply power to the energy storage module 20.

[0053] In the above embodiment, by integrating the third mechanical output component 3031 and the third transmission component 3053 of the pneumatic power generation unit 303 into the air guide shroud 3011, a highly compact and coaxial layout of the three power generation units and the generator 304 is achieved. The controller 40 can directly control the third transmission component 3053, thereby enabling the pneumatic power generation unit 303 to be activated as a backup power source when wind and hydropower generation are insufficient and the remote control valve group 10 urgently needs power. This ensures the timeliness and continuity of power supply even under extreme conditions, improving the emergency response capability and operational reliability of the entire self-generating remote control valve group 1 in complex and variable downhole environments.

[0054] In some embodiments, the self-generated remote control valve group 1 further includes a parameter acquisition module. The parameter acquisition module is disposed in the energy storage module 20 to acquire the voltage parameters of the energy storage module 20, and the energy storage module 20 is also electrically connected to the parameter acquisition module.

[0055] The parameter acquisition module may include a voltage detection element disposed in the energy storage module 20. The voltage detection element can detect the voltage parameters in the energy storage module 20, thereby reflecting the voltage parameters in the energy storage module 20.

[0056] For example, the voltage detection element can detect the voltage parameters in the voltage energy storage module 20 and send the detected voltage parameters to the controller 40. The controller 40 calculates the SOC (State of Charge) value of the energy storage module 20 in the current state based on the received voltage parameters and the preset rated voltage parameters of the energy storage module 20, thereby reflecting the remaining power in the energy storage module 20.

[0057] The above embodiment monitors the voltage parameters of the energy storage module 20 in real time through the parameter acquisition module and converts them into SOC values ​​through the controller 40, enabling the controller 40 to accurately grasp the energy storage status. This provides an important basis for the intelligent scheduling of the wind power generation unit 301, the hydraulic power generation unit 302, and the pneumatic power generation unit 303, realizing closed-loop management between power generation, energy storage, and power consumption. This not only improves the autonomous response and dynamic adaptability of the self-generated remote control valve group 1 to complex working conditions in coal mines, but also further enhances the continuity and operational reliability of power supply to the remote control valve group 10 in the self-generated remote control valve group 1.

[0058] In some embodiments, the controller 40 can achieve: When the voltage parameter is lower than the preset voltage threshold, the control switches the transmission component 305 to connect with the generator 304, thereby supplying power to the energy storage module 20.

[0059] The operator can set a preset voltage threshold in the controller 40. When the voltage parameter of the energy storage module 20 is lower than the preset voltage threshold, the controller 40 controls the third transmission component 3053 in the switching transmission assembly 305 to connect with the generator 304, so as to generate electricity using the compressed air in the compressed air pipeline A3 and then quickly charge the energy storage module 20, ensuring the stable operation of the remote control valve group 10.

[0060] In the above embodiment, the controller 40 monitors the voltage of the energy storage module 20 in real time and compares it with a preset voltage threshold. This enables the automatic activation of the pneumatic power generation unit 303 for rapid charging when the power is insufficient. This not only improves the power maintenance capability and response speed of the energy storage module 20, but also ensures the continuity and operational stability of the power supply of the remote control valve group 10 under complex working conditions in the coal mine, and enhances the overall autonomous regulation and emergency support capability of the self-generated remote control valve group 1.

[0061] In some embodiments, the controller 40 can also achieve: If the remote control valve group 10 does not open or close, the speed of the first transmission component 3051 does not reach the first preset parameter, the speed of the second transmission component 3052 does not reach the second preset parameter, and the voltage parameter of the energy storage module 20 is higher than the preset voltage threshold, the control switching transmission component 305 is disconnected from the generator 304.

[0062] Specifically, based on the characteristics of the first transmission component 3051, when the rotational speed of the first transmission component 3051 does not reach the first preset parameter, the first transmission component 3051 cannot be connected to the generator 304; similarly, based on the characteristics of the second transmission component 3052, when the rotational speed of the second transmission component 3052 does not reach the first preset parameter, the second transmission component 3052 also cannot be connected to the generator 304. In this case, if the voltage parameter of the energy storage module 20 is higher than the preset voltage threshold, there is no need to worry about insufficient power supply to the remote control valve group 10, therefore, there is no need to connect the pneumatic generator unit 303 to charge the energy storage module 20.

[0063] In the above embodiment, when the wind power in the ventilation tunnel A1 and the water supply pipeline A2 are insufficient and the hydropower generation conditions are not met, the remote control valve group 10 is in a silent state and the energy storage module 20 has sufficient remaining power, the controller 40 disconnects the power generation connection, thereby avoiding inefficient or ineffective energy conversion losses and reducing the wear and tear on the transmission components and generator 304. Thus, while ensuring the reliability of power supply, the service life and overall energy efficiency of the self-generated remote control valve group 1 are effectively improved.

[0064] In some embodiments, the energy storage module 20 includes an energy storage battery. The energy storage battery is electrically connected to the generator 304.

[0065] The energy storage module 20 includes an energy storage capacitor. The energy storage capacitor is electrically connected to the generator 304 and is connected in parallel with the energy storage battery.

[0066] Energy storage batteries can ensure a stable output of electrical energy over a long period of time, while energy storage capacitors are suitable for short-term high-power discharge. Therefore, connecting energy storage capacitors and energy storage batteries in parallel can share the high-power load of the energy storage battery and prevent overheating caused by high-current discharge. In addition, since energy storage capacitors have a fast response characteristic, adding energy storage capacitors to the self-generating remote control valve assembly 1 can improve the response speed of the self-generating remote control valve assembly 1, thereby improving the overall efficiency of the self-generating remote control valve assembly 1.

[0067] The above embodiments combine the advantages of long-term stable power supply of energy storage batteries with the fast response and high power support capabilities of energy storage capacitors by connecting energy storage batteries and energy storage capacitors in parallel. This effectively reduces the current pressure on energy storage batteries under short-term high loads, prevents them from overheating and being damaged, improves the response speed and power supply stability of the self-generated remote control valve group 1 in response to sudden working conditions, and thus enhances the reliability of the operation of the self-generated remote control valve group 1.

[0068] This application also provides a remote control device, which includes the self-generated remote control valve group 1 provided in any of the above embodiments. Since the remote control device provided in this application has the self-generated remote control valve group 1 as in any of the above embodiments, it has the beneficial effects of any of the above embodiments regarding the self-generated remote control valve group 1, which will not be described in detail here.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
