Description

Technical Field

[0001] This invention relates to the fields of solar thermal power generation technology and radio observation, specifically providing a dual-purpose device and method for astronomical observation and thermal power generation based on abandoned mining sites. Background Technology

[0002] Faced with the dual challenges of global resources and the environment, the effective reuse of abandoned mining sites has become a focus of attention. Abandoned mining sites not only occupy a large amount of land resources, but their residual geological hazards and environmental problems also urgently need to be addressed.

[0003] In the past, the common methods for dealing with abandoned mining sites were simple landfilling or extensive ecological restoration, which not only consumed a lot of manpower and resources but also failed to fully tap their potential value. In fact, abandoned mining sites usually have advantages such as open terrain and relatively stable electromagnetic environment.

[0004] This invention combines two different categories of astronomical observation with thermal power generation, providing a dual-purpose device and method for astronomical observation and thermal power generation based on abandoned mine sites. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-purpose device and method for astronomical observation and thermal power generation based on abandoned mine sites, so as to overcome the shortcomings of existing technologies that consume a lot of manpower and material resources to abandon mine sites and still fail to tap their potential value.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides a dual-purpose device for astronomical observation and thermal power generation based on an abandoned mine site, comprising a parabolic reflector structure, wherein a plurality of reflectors are provided on the inner surface of the parabolic reflector structure; a first anchoring tower, a second anchoring tower and a third anchoring tower are respectively arranged around the parabolic reflector structure; a receiver is detachably provided at the center of the parabolic reflector structure, and a winch is provided on the top of the first anchoring tower, the second anchoring tower and the third anchoring tower, and the winch is connected to the receiver; When the receiver is an electronic signal receiver, the electronic signal receiver outputs an astronomical observation signal; When the receiver is a thermal energy receiver, the thermal energy receiver is connected in sequence to the steam turbine and the generator.

[0007] Furthermore, the parabolic parameters of the parabolic reflector structure are determined by calculation based on the accuracy requirements of astronomical observation.

[0008] Furthermore, the winch is connected to the receiver via a rope.

[0009] Furthermore, the electronic signal receiver outputs astronomical observation signals via a signal line.

[0010] Furthermore, the heat energy receiver is connected to the steam turbine via a first metal pipe, and the steam turbine is connected to the generator via a second metal pipe.

[0011] Furthermore, the reflector is fixed by a mounting bracket installed on the inner surface of the parabolic reflector structure by water backfilling the base.

[0012] Furthermore, each of the reflectors is equipped with an angle adjustment component, which includes a drive motor, a transmission gear set, and an angle sensor. The drive motor drives the reflector to rotate around its edge rotation axis through the transmission gear set, and the angle sensor monitors the tilt angle of the reflector in real time and feeds it back to the drive motor.

[0013] Furthermore, positioning sensors are installed on the tops of the first, second, and third anchor towers, and these positioning sensors are electrically connected to the control module of the winch.

[0014] Furthermore, both the first and second metal pipes are wrapped with heat tracing cables on their outer surfaces. The heat tracing cables are covered with a flame-retardant insulation layer. Both the first and second metal pipes are equipped with temperature control switches, which are electrically connected to the heat tracing cables. When the temperature of the medium inside the pipe is lower than ℃, the heat tracing cables are automatically activated to heat the pipe.

[0015] Secondly, the present invention provides a method for operating a dual-purpose device for astronomical observation and thermal power generation based on an abandoned mining site, wherein the device includes an astronomical observation mode and a thermal power generation mode: The operation steps of the astronomical observation mode are as follows: The electronic signal receivers are hoisted to the center of the parabolic reflector structure using winches on each anchor tower, and then connected to the back-end equipment. The electronic signal receiver is activated to receive celestial signals and transmit them to the backend equipment. The operation steps of the thermal power generation mode are as follows: The heat receiver was hoisted to the center of the parabolic reflector structure using a winch. The reflector is adjusted to a heat-concentrating state, and the heat energy receiver receives the heat energy from the reflector and heats the medium, which drives the steam turbine to drive the generator to generate electricity.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a dual-purpose device for astronomical observation and thermal power generation based on abandoned mining sites. A receiver is detachably mounted at the center of a parabolic reflector structure, and it is equipped with both electronic signal receivers and thermal energy receivers, allowing for flexible switching between astronomical observation and thermal power generation modes. When using the electronic signal receiver, it can stably receive celestial signals and output astronomical observation data, meeting the scientific research needs of astronomical observation. When the thermal energy receiver is switched to, power generation can be achieved through the linkage of the thermal energy receiver, steam turbine, and generator, adapting to various energy utilization scenarios. This breaks through the limitations of traditional single-function devices, allowing the device to serve both scientific research and observation and create energy value, significantly improving the overall utilization efficiency and application adaptability of the equipment.

[0017] Specifically, the parabolic reflector structure is equipped with a first anchor tower, a second anchor tower, and a third anchor tower. The three-point surrounding support structure can precisely control the installation, disassembly, and positioning of the receiver at the center of the parabolic reflector structure.

[0030] See Figure 1 and Figure 2 This invention provides a dual-purpose device for astronomical observation and thermal power generation based on abandoned mining sites. It includes a parabolic reflector structure 3. The parabolic parameters of the reflector structure 3 are determined through calculations based on the accuracy requirements of astronomical observation. This parameter determination method ensures that the reflector structure 3 provides a signal reception environment that meets accuracy standards for the electronic signal receiver 4 in astronomical observation mode, thereby improving the accuracy of astronomical observation data. Several reflectors 11 are arranged on the inner surface of the reflector structure 3 to concentrate light and heat. A first anchoring tower 1, a second anchoring tower 9, and a third anchoring tower 10 are respectively arranged around the reflector structure 3. These three anchoring towers are used for hoisting and positioning the receiver, providing balanced force support for the installation and adjustment of the receiver through a three-point surrounding distribution. A receiver is detachably installed at the center of the reflector structure 3. By disassembling and replacing different types of receivers, the device can be switched to the corresponding operating mode. The tops of the first anchor tower 1, the second anchor tower 9, and the third anchor tower 10 are all equipped with winches, which are all connected to the receiver. The winches are used to provide hoisting power to realize the installation and disassembly of the receiver at the center of the parabolic reflector structure 3. The lifting position of the receiver is precisely controlled by starting, stopping, and speed regulation.

[0031] like Figure 1As shown, when the receiver is an electronic signal receiver 4, the function of the electronic signal receiver 4 is to receive signals emitted by celestial bodies, and the electronic signal receiver 4 outputs astronomical observation signals. like Figure 2 As shown, when the receiver is a thermal energy receiver 5, the function of the thermal energy receiver 5 is to receive the thermal energy gathered by the reflector 11. The thermal energy receiver 5 is connected to the steam turbine and the generator in sequence, so as to drive the steam turbine to run by heating the internal medium, and then drive the generator to realize the power generation function.

[0032] In a more specific embodiment of the present invention, the winch is connected to the receiver via a rope 2. The rope 2 serves as a connection medium between the winch and the receiver, ensuring the stable transmission of the hoisting force from the winch to the receiver, and achieving smooth lifting and positioning of the receiver.

[0033] In a more specific embodiment of the present invention, the electronic signal receiver 4 outputs astronomical observation signals through the signal line 8. The function of the signal line 8 is to stably transmit the astronomical observation signals received and processed by the electronic signal receiver 4 to the back-end equipment, thereby providing a guarantee for the back-end equipment to further analyze and process the signals.

[0034] In a more specific embodiment of the present invention, the heat energy receiver 5 is connected to the steam turbine through a first metal pipe 6, the first metal pipe 6 being used to transfer the heated medium in the heat energy receiver 5 to the steam turbine; the steam turbine is connected to the generator through a second metal pipe 7, the second metal pipe 7 being used to realize the connection of related medium or power transmission between the steam turbine and the generator.

[0035] In a more specific embodiment of the present invention, the reflector 11 is fixed by a water-reverse injection base on the inner surface of the parabolic reflector structure 3 and a mounting bracket. The water-reverse injection base is designed to fit tightly against the inner surface of the parabolic reflector structure 3. Combined with the mounting bracket, this effectively prevents the reflector 11 from shifting or falling off due to external forces during long-term use, thus ensuring the accuracy of the working position of the reflector 11.

[0036] In a more specific embodiment of the present invention, each reflector 11 is equipped with an angle adjustment component, which includes a drive motor, a transmission gear set, and an angle sensor. The drive motor drives the reflector 11 to rotate around its edge rotation axis through the transmission gear set. The angle sensor monitors the tilt angle of the reflector 11 in real time and feeds it back to the drive motor. The function of the angle adjustment component is to achieve precise control of the tilt angle of the reflector 11. Through the real-time feedback of the angle sensor, the drive motor can adjust the transmission gear set in a timely manner according to the needs, thereby changing the angle of the reflector 11 to meet the requirements of light reflection direction or signal reception assistance in different operating modes.

[0037] In a more specific embodiment of the present invention, positioning sensors are provided on the top of the first anchoring tower 1, the second anchoring tower 9, and the third anchoring tower 10. The positioning sensors are electrically connected to the control module of the winch. The function of the positioning sensors is to monitor the position information of the receiver in real time and transmit the data to the control module of the winch, so that the control module can adjust the operating status of the winch in a timely manner according to the position data and achieve accurate positioning of the receiver.

[0038] In a more specific embodiment of the present invention, the outer surfaces of both the first metal pipe 6 and the second metal pipe 7 are wound with heat tracing cables. The heat tracing cables are wrapped with a flame-retardant insulation layer, which serves to prevent fire and provide insulation, thus avoiding safety hazards during operation. Furthermore, both the first metal pipe 6 and the second metal pipe 7 are equipped with temperature control switches, which are electrically connected to the heat tracing cables. When the temperature of the medium inside the pipe is below 5°C, the heat tracing cables are automatically activated for heating. The temperature control switches monitor the temperature of the medium inside the pipe in real time, and through linkage with the heat tracing cables, automatically regulate the temperature of the medium inside the pipe, ensuring that the medium flows within a suitable temperature range and guaranteeing the stable operation of the thermal power generation mode.

[0039] In another embodiment of the present invention, the present invention provides a method for operating a dual-purpose device for astronomical observation and thermal power generation based on an abandoned mine site. The device, described above, includes an astronomical observation mode and a thermal power generation mode. The electronic signal receiver 4 is hoisted to the center of the parabolic reflector structure 3 by the winches of each anchor tower, so that the electronic signal receiver 4 can be connected to the back-end equipment. The electronic signal receiver 4 is activated to receive celestial signals and transmit them to the backend equipment. In a preferred embodiment of the present invention, during the operation of the astronomical observation mode, the electronic signal receiver 4 is hoisted to the center of the parabolic reflector structure 3 using the hoisting power of the winches installed on the top of each anchor tower. During this process, the positioning sensors on the top of each anchor tower monitor the position of the electronic signal receiver 4 in real time and transmit the data to the control module of the winch. The control module regulates the operation of the winch to ensure the precise positioning of the electronic signal receiver 4. Then, the electronic signal receiver 4 is connected to the back-end equipment to prepare for the transmission and processing of astronomical observation signals. The electronic signal receiver 4 is then activated and begins to receive celestial signals. The received celestial signals are transmitted to the back-end equipment through the signal line 8. The back-end equipment analyzes and processes the signals to complete the astronomical observation work.

[0040] The operating steps for thermal power generation are as follows: The heat receiver 5 is hoisted to the center of the parabolic reflector structure 3 using a winch. The reflector 11 is adjusted to a heat-concentrating state, and the heat energy receiver 5 receives the heat energy from the reflector 11 and heats the medium, thereby driving the steam turbine to drive the generator to generate electricity.

[0041] In a preferred embodiment of the present invention, during the operation of the thermal power generation mode, the heat energy receiver 5 is hoisted to the center of the parabolic reflector structure 3 using winches at the top of each anchoring tower. A positioning sensor and the winch control module work together to achieve precise installation of the heat energy receiver 5. The angle adjustment component of the reflector 11 is activated, and the drive motor, under the feedback of the angle sensor, drives the reflector 11 to rotate around its axis via a transmission gear set, adjusting the reflector 11 to a heat-gathering state. At this time, the heat energy receiver 5 receives the heat energy gathered by the reflector 11, which heats the medium inside the receiver 5. The heated medium is then transmitted to the turbine through the first metal pipe 6, driving the turbine to operate. The operating turbine, connected to the second metal pipe 7, drives the generator to generate electricity, completing the thermal power generation process. Throughout the thermal power generation operation, temperature control switches on the first metal pipe 6 and the second metal pipe 7 monitor the temperature of the medium inside the pipes in real time. When the temperature is below 5°C, the heating cable is automatically activated to heat the pipes, ensuring normal flow of the medium and stable operation of the power generation process.

[0042] This invention utilizes abandoned mining sites as its application scenario, fully leveraging the idle space resources of these sites to construct a parabolic reflector structure 3 and anchoring towers, without requiring additional land resources. This effectively solves the problem of long-term idleness and waste of land resources in abandoned mining sites. Through the functional transformation and utilization of abandoned mining sites, land resources are revitalized, aligning with the green development concept of resource recycling, while simultaneously reducing land costs during device construction. Compared to constructing separate astronomical observation and thermal power generation equipment, this device, through its parabolic reflector structure, anchoring towers, and winches, integrates both functions, significantly reducing the cost of redundant equipment construction and lowering the initial investment threshold for scientific research and energy projects. The absence of large-scale modifications to the basic structure reduces manpower and material consumption during operation and maintenance, further lowering the overall life-cycle operating costs of the equipment and demonstrating high economic feasibility.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
