Description

Technical Field

[0001] The invention belongs to the technical field of electric power engineering, and in particular relates to an auxiliary power supply device for a thermal power generator set. Background Art

[0002] A thermal power generating unit is a power generation equipment that uses fossil fuels (such as coal, natural gas or oil) to 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 boilers, steam turbines, generators, condensers, and control systems. 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 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 to adapt to changes in power demand. However, its combustion process will produce a large amount of greenhouse gases such as carbon dioxide, which will affect the environment. At the same time, it also needs to deal with combustion exhaust gas and solid waste, so it faces challenges in environmental protection and sustainable use of resources. With the continuous development of technology, thermal power plants are also constantly updating and adopting more advanced combustion and power generation technologies to improve energy efficiency, reduce emissions and reduce environmental impact.

[0003] During use, the thermal power generating set needs to be opened and closed so that the generating set can be powered in time during the power generation process. The existing auxiliary power supply equipment for thermal power generating sets is mostly manually closed by people wearing insulating clothing when working. The process of manually wearing specific clothing is troublesome and requires close contact with the interior, which poses a safety hazard. At the same time, the power supply equipment uses a single switch to work, and it is impossible to control the interior of the auxiliary power supply equipment step by step, resulting in a large overall energy consumption inside. In addition, when the auxiliary power supply equipment is working, it is easy to cause aging of the internal circuit due to the long-term invasion of the high temperature in the boiler of the thermal power generating set. In addition, under the continuous high temperature, the interior of the auxiliary power supply equipment is generally relatively closed and the air is not circulated, resulting in poor internal heat dissipation performance, thereby greatly reducing the working performance of the auxiliary power supply equipment for the thermal power generating set. Summary of the invention

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

[0005] The technical solution adopted to solve the above technical problems is: to provide an auxiliary power supply device for a thermal power generating set, comprising a main body, a door body movably connected to the front end of the main body, a power supply mechanism installed inside the main body, and a closing mechanism installed inside the main body; 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 flow guide mechanism is installed at the bottom of the support plate; A top plate is fixedly connected to the top of the main body, and a plurality of air flow holes are opened on the surface of the top plate.

[0006] Furthermore, the power supply mechanism includes a plurality of fixed plates fixedly connected to the rear end of the inner wall of the main body, wherein the front ends of two of the fixed plates are fixedly connected to power supplies, the front end of the top of the power supply is fixedly connected to a plurality of first transmission lines, the other ends of the plurality of first transmission lines are fixedly connected to a first circuit breaker, the front end of the first circuit breaker is movably connected to a first closing switch, the rear end of the top of the power supply is fixedly connected to a plurality of second transmission lines, the other ends of the plurality of second transmission lines are 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, and the front ends of the plurality of additional fixed plates are fixedly connected to the first circuit breaker and the second circuit breaker, respectively.

[0007] Through the above technical scheme, when in use, through the mutual connection of the power supply mechanism, the auxiliary power supply equipment can ensure the normal power supply to the thermal power generator set when in use, and at the same time, the normal power supply is ensured by the double-control switch, so that the power supply equipment can perform a graded power supply method, and thus it can be more energy-saving when in use. Specifically, the device is separated from the main body by a fixing plate to facilitate better heat dissipation of equipment components, and the power supply device, the first circuit breaker and the second circuit breaker are fixed on the fixing plate, and then they are connected using multiple first transmission lines and multiple second transmission lines, and then they are connected to the thermal power generator set and an external power source through multiple output connectors, so that the power supply demand of the thermal power generator set is normally supplied. At the same time, when the auxiliary power supply equipment is in normal operation, the first circuit breaker is used to connect the switch to ensure its normal operation. When the generator set has a power supply demand, the second circuit breaker is used to provide auxiliary power supply, so that the auxiliary power supply equipment can save energy while maintaining normal power supply demand.

[0008] Furthermore, 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 to a driving shaft, the other end of the driving shaft is fixedly connected to a circular plate, the front end of the circular plate is rotatably connected to a first connecting rod, the inner wall surface of the main body is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is rotatably connected to a balance rod, the front ends of the balance rod are rotatably connected to second connecting rods, the outer walls of the two second connecting rods are fixedly connected to a first connecting sleeve, the tops of the two first connecting sleeves are fixedly connected to a spring, the other ends of the two springs are fixedly connected to a second connecting sleeve, the outer walls of the two second connecting sleeves are fixedly connected to a third connecting rod, the outer walls of the two third connecting rods are slidably connected to the first support rod, 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, and the other ends of the two first support rods are fixedly connected to the corresponding first closing switch.

[0009] By means of the above technical scheme, when in use, the closing mechanism is used to adjust the first circuit breaker and the second circuit breaker, so that the operator's contact is avoided as much as possible when opening and closing the switch, thereby reducing safety hazards. At the same time, when tripping, the first closing switch and the second closing switch can be buffered to avoid severe impact and damage to the first circuit breaker and the second circuit breaker, thereby protecting the electrical appliance. Specifically, the drive motor at the rear end of the starter body drives the circular plate of the drive shaft to rotate, and then 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 up. Then 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 maintains normal operation. When the thermal power generator set needs power supply, at this time, the circular plate continues to rotate until the balance rod is lifted up to the other side. At this time, the spring on one side returns to its original position. When the second closing switch is closed, the first closing switch trips. Under the buffering of the spring on one side, the large movement is reduced, thereby reducing the operation of the operator while playing a certain protective role on the equipment and saving resources.

[0010] Furthermore, 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 to a driver, the top of the driver is rotatably connected to a fan head, the outer wall of the fan head is fixedly connected to a plurality of fan blades, the bottom of the funnel plate is fixedly connected to a pipe, the other end of the pipe is provided with a filter, a spiral plate is provided inside the pipe, the funnel plate passes through the bottom of the main body, and the pipe spirals around the bottom of the main body.

[0011] Through the above technical scheme, when in use, the thermal power generating set generally adopts the combustion method when generating electricity, so that the auxiliary power supply equipment is at high temperature for a long time, and the internal temperature is reduced by the cooling mechanism to prevent the internal lines from aging easily at high temperature. 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 blades on the fan head to rotate, so that the airflow enters the pipeline through the filter. Under the rotation of the spiral plate, the airflow can absorb the cold air from the ground as much as possible to achieve cooling of the airflow. Then the cold airflow is discharged into the equipment through the pipeline, thereby achieving internal cooling and reducing pipeline redundancy.

[0012] Furthermore, the air guide mechanism includes a support column fixedly connected to the bottom of the support plate, the outer wall of the support column is fixedly connected to a fixing ring, the outer wall of the fixing ring is rotatably connected to a plurality of telescopic rods, the outer wall of the support column is slidably connected to a connecting ring, the outer wall of the connecting ring is fixedly connected to a sliding rod, the outer wall of the connecting ring is movably connected to a plurality of second support rods, wherein a guide cloth is fixedly connected between two second support rods, the top of the fan head is fixedly connected to a cylinder, a slide is provided inside the cylinder, and a plurality of openings are opened on 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 slide, the slide is in the shape of an arc-shaped closed loop, the plurality of second support rods are respectively rotatably connected to the corresponding telescopic rods, and the plurality of inner walls of the openings are respectively slidably connected to the corresponding second support rods.

[0013] Through the above technical scheme, when in use, while the cooling mechanism discharges a certain amount of cold air into the interior for cooling, the guide mechanism is used to allow the cold air flow to pass completely through the corners of the main body, thereby achieving complete cooling inside the equipment. Specifically, as the fan head rotates, the cylinder is driven to rotate, and then the sliding rod on the outer wall of the connecting ring will slide along the slide, so that the connecting ring can slide up and down along the support column, driving multiple second support rods to move downward along the corresponding openings, and while moving, it will cooperate with the corresponding telescopic rods, and then the guide cloth will open or contract, so that the cold air flow will diffuse to the surroundings when the guide cloth is opened when it is blown out, thereby achieving overall cooling inside the equipment. At the same time, when the guide cloth contracts, it is blown upward and discharged from multiple airflow holes, thereby accelerating the exchange of internal and external airflows, and avoiding aging of internal circuits due to long-term high temperature conditions.

[0014] The beneficial effects of the present invention are as follows: (1) By designing the power supply mechanism, closing mechanism, cooling mechanism and diversion mechanism, the present invention can avoid direct manual contact to close the auxiliary power supply equipment for the thermal power generator when it is put into use, thereby reducing the overall danger of the overall power supply equipment when in use. At the same time, when the temperature is high, the internal heat can be quickly dissipated to avoid the internal circuit aging rapidly at high temperature, thereby greatly improving the performance of the auxiliary power supply equipment; (2) By designing the power supply mechanism and closing mechanism, the present invention can use the mechanical switch closing operation to avoid direct manual contact when the auxiliary power supply equipment is put into use, and can control the internal power supply to supply power according to the power demand of the generator set. At the same time, it can reduce the violent collision of the switch when tripping, thereby improving the service life of the circuit breaker; (3) By designing the cooling mechanism and diversion mechanism, since the thermal power generator is under high temperature for a long time, the underground temperature is used to cool the auxiliary power supply equipment, and the cold air flow passing through the internal can be fully passed through the power supply equipment through the diversion mechanism, accelerating the circulation of the internal air flow and reducing the aging of the internal circuit, thereby greatly reducing the safety hazards of the auxiliary power supply equipment.
