Description

Technical Field

[0001] The present invention belongs to the technical field of power engineering, and particularly relates to an auxiliary power supply device for a thermal power generating unit. Background Art

[0002] A thermal power generating unit is a power generation device that uses fossil fuels (such as coal, natural gas, or oil) to burn and generate heat energy, then converts the heat energy into mechanical energy, and finally converts it into electrical energy. A thermal power generating unit usually includes main components such as a boiler, a steam turbine, a generator, a condenser, and a control system. The boiler is responsible for converting the heat energy generated by fuel combustion into steam. The steam turbine drives the rotating generator through the pressure of the steam, and the generator converts mechanical energy into electrical energy. The thermal power generating unit has the advantages of stable operation and high power generation efficiency, and can flexibly adjust the power generation amount to adapt to the change of power demand. However, its combustion process will produce a large amount of greenhouse gases such as carbon dioxide, which has an impact on the environment. At the same time, it is also necessary to treat combustion exhaust gas and solid waste. Therefore, it faces challenges in environmental protection and sustainable use of resources. With the continuous development of technology, thermal power plants are also constantly updated, adopting more advanced combustion and power generation technologies to improve energy utilization efficiency, reduce emissions, and reduce the impact on the environment.

[0003] During the use of a thermal power generating unit, it is necessary to perform opening and closing operations on it so that the generating unit can be powered in time during the power generation process. Most of the existing auxiliary power supply devices for thermal power generating units perform manual closing of the switch when working by wearing insulating clothing manually. The process of manually wearing specific clothing is troublesome and requires close contact with the inside, thus there are potential safety hazards. At the same time, the power supply device uses a single electric switch to work and cannot perform hierarchical control on the inside of the auxiliary power supply device, resulting in a relatively large overall energy consumption inside. In addition, when the auxiliary power supply device is working, due to being invaded by the high temperature in the boiler of the thermal power generating unit for a long time, it is easy to cause the aging of the internal circuit. And under the continuous high temperature, the inside of the general auxiliary power supply device is relatively closed and the air does not circulate, resulting in poor internal heat dissipation performance, thus greatly reducing the working performance of the auxiliary power supply device for the thermal power generating unit. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an auxiliary power supply device for a thermal power generating unit.

[0005] The technical solution adopted to solve the above technical problem is: to provide an auxiliary power supply device for a thermal power generating unit, including a main body, a door body is movably connected to the front end of the main body, a power supply mechanism is installed inside the main body, and a closing mechanism is installed inside the main body;

[0006] A funnel plate is provided at the bottom of the main body. A cooling mechanism is installed inside the main body. A support plate is fixedly connected to the inner wall of the main body, and a diversion mechanism is installed at the bottom of the support plate.

[0007] The top of the main body is fixedly connected with a top plate, and a plurality of air flow holes are formed on the surface of the top plate.

[0008] Furthermore, the power supply mechanism includes a plurality of fixing plates fixedly connected to the rear end of the inner wall of the main body. A power supply is fixedly connected to the front ends of two of the fixing plates. A plurality of first transmission lines are fixedly connected to the front end of the top of the power supply. The other ends of the plurality of first transmission lines are all fixedly connected to a first circuit breaker. The front end of the first circuit breaker is movably connected to a first closing switch. A plurality of second transmission lines are fixedly connected to the rear end of the top of the power supply. The other ends of the plurality of second transmission lines are all fixedly connected to a second circuit breaker. The front end of the second circuit breaker is fixedly connected to a second closing switch. A plurality of output connectors are fixedly connected to one side of the power supply. The front ends of the other plurality of fixing plates are respectively fixedly connected to the first circuit breaker and the second circuit breaker.

[0009] Through the above technical solutions, during use, through the mutual connection of the power supply mechanism, the auxiliary power supply device can ensure the normal power supply to the thermal power generating unit during use. At the same time, through the dual-control switch, the normal power supply can be ensured, enabling the power supply device to adopt a hierarchical power supply method, and thus being more energy-saving during use. Specifically, the device is separated from the main body by the fixing plates to facilitate better heat dissipation of the device components. The power supply, the first circuit breaker, and the second circuit breaker are fixed on the fixing plates, and then they are connected by a plurality of first transmission lines and a plurality of second transmission lines. Subsequently, they are connected to the thermal power generating unit and the external power supply through a plurality of output connectors, so that the power supply requirements of the thermal power generating unit can be normally supplied. At the same time, when the auxiliary power supply device is operating normally, the first circuit breaker is used for the connection of the switch to ensure its normal operation. When the generating unit has a power supply requirement, the second circuit breaker is used to provide auxiliary power supply, so that the auxiliary power supply device can save energy while maintaining the normal power supply requirement.

[0010] Further, the closing mechanism includes a driving motor fixedly connected to the rear end of the main body. The output end of the driving motor is fixedly connected with a driving shaft. The other end of the driving shaft is fixedly connected with a circular plate. The front end of the circular plate is rotatably connected with a first connecting rod. The inner wall surface of the main body is fixedly connected with a rotating shaft. The outer wall of the rotating shaft is rotatably connected with a balance rod. The front end of the balance rod is rotatably connected with two second connecting rods on both sides. Both outer walls of the two second connecting rods are fixedly connected with first connecting sleeves. Springs are fixedly connected to the tops of the two first connecting sleeves. The other ends of the two springs are fixedly connected with second connecting sleeves. Third connecting rods are fixedly connected to the outer walls of the two second connecting sleeves. First support rods are slidably connected to the outer walls of the two third connecting rods. The other end of the first connecting rod is rotatably connected to one side of the balance rod. The two second connecting sleeves are respectively slidably connected to the corresponding second connecting rods. The other ends of the two first support rods are fixedly connected to the corresponding first closing switches.

[0011] Through the above technical solution, during use, the closing mechanism is used to adjust the first circuit breaker and the second circuit breaker, so as to avoid the contact of operators as much as possible during opening and closing, reduce potential safety hazards. At the same time, when tripping, it can provide buffering for the first closing switch and the second closing switch to avoid damage to the first circuit breaker and the second circuit breaker caused by violent impact, thereby protecting the electrical appliances. Specifically, start the driving motor at the rear end of the main body to drive the circular plate of the driving shaft to rotate. Subsequently, the first connecting rod drives the balance rod to make an inclined movement on both sides. When moving to one side, one of the springs will be compressed upward until the first closing switch is completely lifted. Subsequently, the first closing switch makes an arc movement, and then the first support rod slides on the third connecting rod. At this time, the power supply equipment operates normally. When the thermal power generating unit needs to supply power, at this time, the circular plate continues to rotate until the balance rod lifts to the other side. At this time, the spring on one side returns to its original position. When the second closing switch is closed, at this time, the first closing switch trips. Under the buffering of the spring on one side, the large-scale movement is reduced, so that while reducing the operation of the operator, it plays a certain role in protecting the equipment and saving resources.

[0012] Further, the cooling mechanism includes a support frame fixedly connected to the inner wall of the funnel plate. The other end of the support frame is fixedly connected with a driver. The top of the driver is rotatably connected with a fan head. Multiple fan blades are fixedly connected to the outer wall of the fan head. A pipe is fixedly connected to the bottom of the funnel plate. A filter screen is provided at the other end of the pipe. A spiral plate is provided inside the pipe. The funnel plate penetrates through the bottom of the main body, and the pipe spirals around the bottom of the main body.

[0013] Through the above technical solution, during use, when a thermal power generating unit generates electricity, it generally adopts a combustion method, which causes the auxiliary power supply equipment to be at a high temperature for a long time. The cooling mechanism is used to cool the interior to prevent the internal wires from being easily aged at high temperatures. Specifically, the pipeline is laid underground in advance, and then the driver at the other end of the support frame is started to drive the multiple fan blades on the fan head to rotate, so that the air flow passes through the filter screen and enters the pipeline. Under the rotation of the spiral plate, the air flow can absorb the cold air in the ground as much as possible to achieve the cooling of the air flow. Then the cold air flow is discharged into the equipment interior through the pipeline, thereby achieving the interior cooling and reducing the pipeline redundancy at the same time.

[0014] Furthermore, the flow guiding mechanism includes support columns fixedly connected to the bottom of the support plate. A fixed ring is fixedly connected to the outer wall of the support column. A plurality of telescopic rods are rotatably connected to the outer wall of the fixed ring. A connecting ring is slidably connected to the outer wall of the support column. A sliding rod is fixedly connected to the outer wall of the connecting ring. A plurality of second support rods are movably connected to the outer wall of the connecting ring. A flow guiding cloth is fixedly connected between every two of the second support rods. A cylinder is fixedly connected to the top of the fan head. A slideway is provided inside the cylinder. A plurality of openings are formed at the top of the cylinder. The bottom of the support column is rotatably connected to the fan head. The other end of the sliding rod is slidably connected to the slideway. The slideway is in an arc-shaped closed loop. The plurality of second support rods are respectively rotatably connected to the corresponding telescopic rods. The inner walls of the plurality of openings are respectively slidably connected to the corresponding second support rods.

[0015] Through the above technical solution, during use, while the cooling mechanism discharges a certain amount of cold air into the interior for cooling, the flow guiding mechanism is used to completely guide the cold air flow through the corners of the main body, thereby achieving the complete cooling of the equipment interior. Specifically, as the fan head rotates, it drives the cylinder to rotate. Then the sliding rod on the outer wall of the connecting ring will slide along the slideway, enabling the connecting ring to slide up and down along the support column, driving the plurality of second support rods to move downward along the corresponding openings. And during the movement, it will cooperate with the corresponding telescopic rods. Then the flow guiding cloth will open or contract, so that the cold air flow will spread around when the flow guiding cloth opens when it is blown out, achieving the overall cooling of the equipment interior. At the same time, when the flow guiding cloth contracts, it will blow upward and be discharged from the plurality of air flow holes, accelerating the exchange of the internal air flow and the external air flow, and avoiding the aging of the internal wires under high temperature for a long time.

[0016] The beneficial effects of the present invention are as follows: (1) By designing a power supply mechanism, a closing mechanism, a cooling mechanism, and a diversion mechanism, when the auxiliary power supply device for a thermal power generating unit is put into use, it can avoid manual direct contact for closing, reducing the overall danger during the use of the entire power supply device. At the same time, in the case of relatively high temperatures, it can quickly dissipate heat inside, preventing the internal circuits from aging rapidly at high temperatures, thus greatly improving the performance of the auxiliary power supply device; (2) By designing a power supply mechanism and a closing mechanism, when the auxiliary power supply device is put into use, mechanical operations can be used for switch closing, avoiding direct manual contact and being able to control the internal power supply. It can supply power according to the power consumption requirements of the generating unit, and at the same time, it can reduce the violent collision of the switch during tripping, thereby extending the service life of the circuit breaker; (3) By designing a cooling mechanism and a diversion mechanism, since the thermal power generator is in a high-temperature condition for a long time, the underground temperature is used to cool the auxiliary power supply device. The cold air flow passing through the inside can comprehensively pass through the inside of the power supply device through the diversion mechanism, accelerating the internal air flow and reducing the aging of the internal circuits, thus greatly reducing the potential safety hazards of the auxiliary power supply device.

A second closing switch 308 is fixedly connected to the front end of the second circuit breaker 307. A plurality of output connectors 309 are fixedly connected to one side of the power supply 302. The front ends of the other plurality of fixing plates 301 are respectively fixedly connected to the first circuit breaker 304 and the second circuit breaker 307. During use, through the mutual connection of the power supply mechanism 3, the auxiliary power supply device can ensure the normal power supply to the thermal power generating unit during use. At the same time, the normal power supply is ensured through the double-control switch, enabling the power supply device to adopt a hierarchical power supply method, thereby being more energy-efficient during use. Specifically, the device is separated from the main body 1 through the fixing plates 301 to facilitate better heat dissipation of the device components. The power supply 302, the first circuit breaker 304, and the second circuit breaker 307 are fixed on the fixing plates 301, and then they are connected using a plurality of first transmission lines 303 and a plurality of second transmission lines 306. Subsequently, they are connected to the thermal power generating unit and an external power supply through a plurality of output connectors 309, so that the power supply requirements of the thermal power generating unit are normally supplied. At the same time, when the auxiliary power supply device is operating normally, the first circuit breaker 304 is used for switch connection to ensure its normal operation. When the generating unit has a power supply requirement, auxiliary power supply is provided by using the second circuit breaker 307, so that the auxiliary power supply device can save energy while maintaining normal power supply requirements.

[0030] As Figures 5-6As shown, a closing mechanism 4 is installed inside the main body 1, and the closing mechanism 4 includes a driving motor 401 fixedly connected to the rear end of the main body 1, the output end of the driving motor 401 is fixedly connected to a driving shaft 402, the other end of the driving shaft 402 is fixedly connected to a circular plate 403, the front end of the circular plate 403 is rotatably connected to a first connecting rod 404, the inner wall surface of the main body 1 is fixedly connected to a rotating shaft 405, the outer wall of the rotating shaft 405 is rotatably connected to a balancing rod 406, the front ends of the balancing rod 406 are rotatably connected to second connecting rods 407, the outer walls of the two second connecting rods 407 are fixedly connected to first connecting sleeves 408, and the two first connecting sleeves 409 are fixedly connected to the outer walls of the two second connecting rods 407. 08 are fixedly connected with springs 409 at the top, the other ends of the two springs 409 are fixedly connected with second connecting sleeves 410, the outer walls of the two second connecting sleeves 410 are fixedly connected with third connecting rods 411, the outer walls of the two third connecting rods 411 are slidably connected with first supporting rods 412, the other end of the first connecting rod 404 is rotatably connected to one side of the balance rod 406, the two second connecting sleeves 410 are respectively slidably connected to the corresponding second connecting rods 407, the other ends of the two first supporting rods 412 are fixedly connected to the corresponding first closing switches 305, and when in use, the closing mechanism 4 is used to close the first circuit breaker 304 and the second The circuit breaker 307 is adjusted to avoid contact with the operator as much as possible when opening and closing the switch, thereby reducing safety hazards. At the same time, when tripping, it can provide a buffer for the first closing switch 305 and the second closing switch 308 to avoid damage to the first circuit breaker 304 and the second circuit breaker 307 caused by severe impact, thereby protecting the electrical appliance. Specifically, the driving motor 401 at the rear end of the starter body 1 drives the circular plate 403 of the driving shaft 402 to rotate, and then the first connecting rod 404 drives the balancing rod 406 to make an inclined movement on both sides. When moving to one side, one of the springs 409 will be compressed upward until it is completely pushed up. The first closing switch 305 is started, and then the first closing switch 305 makes an arc motion and then the first support rod 412 slides on the third connecting rod 411. At this time, the power supply equipment maintains normal operation. When the thermal power generator set needs power supply, at this time, the circular plate 403 continues to rotate until the balance rod 406 is pushed up to the other side. At this time, the spring 409 on one side returns to its original position. When the second closing switch 308 is closed, the first closing switch 305 trips. Under the buffering of the spring 409 on one side, the large movement is reduced, thereby reducing the operation of the operator while protecting the equipment to a certain extent and saving resources.

[0031] like Figures 7-8As shown in the figure, a funnel plate 5 is provided at the bottom of the main body 1, and a cooling mechanism 6 is installed inside the main body 1. The cooling mechanism 6 includes a support frame 601 fixedly connected to the inner wall of the funnel plate 5. The other end of the support frame 601 is fixedly connected to a driver 602. The top of the driver 602 is rotatably connected to a fan head 603. A plurality of fan blades 604 are fixedly connected to the outer wall of the fan head 603. The bottom of the funnel plate 5 is fixedly connected to a pipe 605. The other end of the pipe 605 is provided with a filter screen 606. A spiral plate 607 is provided inside the pipe 605. The funnel plate 5 penetrates through the bottom of the main body 1, and the pipe 605 spirals around the bottom of the main body 1. When in use, the thermal power generating unit generally uses combustion to generate electricity, so that the auxiliary power supply equipment is in a high temperature for a long time. The inside is cooled by the cooling mechanism 6 to prevent the internal wires from being easily aged at high temperatures. Specifically, the pipe 605 is laid underground in advance, and then the driver 602 at the other end of the support frame 601 is started to drive the plurality of fan blades 604 on the fan head 603 to rotate, so that the air flow enters the pipe 605 through the filter screen 606. Under the rotation of the spiral plate 607, the air flow can absorb the cold air in the ground as much as possible to achieve the cooling of the air flow. Then the cold air flow is discharged into the equipment through the pipe 605, thereby achieving the cooling of the inside and reducing the redundancy of the pipe 605.

[0032] As Figures 8-10As shown, a support plate 7 is fixedly connected to the inner wall of the main body 1. A flow guiding mechanism 8 is installed at the bottom of the support plate 7. The top of the main body 1 is fixedly connected to a top plate 9. A plurality of air flow holes 10 are formed on the surface of the top plate 9. The flow guiding mechanism 8 includes a support column 801 fixedly connected to the bottom of the support plate 7. A fixed ring 802 is fixedly connected to the outer wall of the support column 801. A plurality of telescopic rods 803 are rotatably connected to the outer wall of the fixed ring 802. A connecting ring 804 is slidably connected to the outer wall of the support column 801. A sliding rod 805 is fixedly connected to the outer wall of the connecting ring 804. A plurality of second support rods 806 are movably connected to the outer wall of the connecting ring 804. A flow guiding cloth 807 is fixedly connected between every two of the second support rods 806. The top of the fan head 603 is fixedly connected to a cylinder 808. A slideway 809 is arranged inside the cylinder 808. A plurality of openings 810 are formed at the top of the cylinder 808. The bottom of the support column 801 is rotatably connected to the fan head 603. The other end of the sliding rod 805 is slidably connected to the slideway 809. The slideway 809 is in an arc-shaped closed loop. The plurality of second support rods 806 are respectively rotatably connected to the corresponding telescopic rods 803. The inner walls of the plurality of openings 810 are respectively slidably connected to the corresponding second support rods 806. During use, while the cooling mechanism 6 discharges a certain amount of cold air into the interior for cooling, the flow guiding mechanism 8 is used to completely pass the cold air flow through the corners of the main body 1, thereby achieving complete cooling inside the device. Specifically, as the fan head 603 rotates, it drives the cylinder 808 to rotate. Then, the sliding rod 805 on the outer wall of the connecting ring 804 will slide along the slideway 809, enabling the connecting ring 804 to slide up and down along the support column 801, driving the plurality of second support rods 806 to move downward along the corresponding openings 810. And during the movement, it will cooperate with the corresponding telescopic rods 803. As a result, the flow guiding cloth 807 will open or contract, causing the cold air flow to spread around when the flow guiding cloth 807 opens during blowing, achieving overall cooling inside the device. At the same time, when the flow guiding cloth 807 contracts, it blows upward and is discharged from the plurality of air flow holes 10, accelerating the exchange of internal and external air flows and preventing the aging of internal circuits under high temperature for a long time.

[0033] The working principle of this embodiment is as follows. The device is separated from the main body 1 by the fixing plate 301. The power supply 302, the first circuit breaker 304, and the second circuit breaker 307 are fixed on the fixing plate 301. Then, multiple first transmission lines 303 and multiple second transmission lines 306 are used to connect them. Subsequently, it is connected to the thermal power generating unit and the external power supply through multiple output connectors 309. The drive motor 401 at the rear end of the main body 1 is started to drive the circular plate 403 of the drive shaft 402 to rotate. Then, the first connecting rod 404 drives the balance rod 406 to make an inclined movement on both sides. When moving to one side, it will compress one of the springs 409 upward until the first closing switch 305 is completely lifted. Then, the first closing switch 305 makes an arc movement, and thus the first support rod 412 slides on the third connecting rod 411. At this time, the power supply equipment operates normally. When the thermal power generating unit needs power supply, at this time, the circular plate 403 continues to rotate until the balance rod 406 lifts to the other side. At this time, the spring 409 on one side returns to its original position. When the second closing switch 308 is closed, at this time, the first closing switch 305 trips. Under the buffering of the spring 409 on one side, the large-amplitude movement is reduced. After that, the pipeline 605 is laid underground in advance. Then, the driver 602 at the other end of the support frame 601 is started to drive the multiple fan blades 604 on the fan head 603 to rotate, so that the air flow enters the pipeline 605 through the filter screen 606. Under the rotation of the spiral plate 607, the air flow can absorb the cold air in the ground as much as possible to achieve the cooling of the air flow. Then, the cold air flow is discharged into the equipment through the pipeline 605. As the fan head 603 rotates, the cylinder 808 is driven to rotate. Then, the sliding rod 805 on the outer wall of the connecting ring 804 will slide along the slideway 809, so that the connecting ring 804 can slide up and down along the support column 801, driving the multiple second support rods 806 to move downward along the corresponding openings 810. And at the same time of the movement, it will cooperate with the corresponding telescopic rods 803. Thus, the flow guiding cloth 807 will open or contract, so that the cold air flow will diffuse around when the flow guiding cloth 807 opens when blowing out, and at the same time, it will blow upward when the flow guiding cloth 807 contracts and is discharged from the multiple air holes 10, accelerating the exchange of the internal air flow and the external air flow. Thus, the working process of the entire auxiliary power supply equipment is completed.

[0034] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
