Description

Technical Field

[0001] This invention relates to the field of smart grid technology, specifically to a noise reduction and cooling environmental protection device for smart grid substations based on intelligent control. Background Technology

[0002] The smart grid is an upgraded form of the traditional power system supported by digital, information, and intelligent technologies. It is a highly integrated, two-way interactive, and self-healing modern power network. With "safety and reliability, economic efficiency, cleanliness and environmental protection, and flexible interaction" as its core objectives, it achieves intelligent management of the entire power chain from production, transmission, distribution to consumption by integrating advanced sensing and measurement, communication networks, data analysis, and automatic control technologies. It is a key infrastructure for addressing the new energy revolution, energy transition, and the upgrading of social electricity demand.

[0003] A substation is a core hub in a power system that connects power generation, transmission, and distribution. Its main functions are to transform voltage, distribute electrical energy, control the direction of power flow, and ensure the safe and stable transmission of electricity. It uses a series of electrical devices (such as transformers, switchgear, and protection devices) to adjust the voltage of high-voltage electricity generated by power plants (or received from transmission lines), then distributes it to different distribution lines, and finally delivers it to industrial users, residential communities, and other electricity consumers.

[0004] The patent document with publication number CN113437679A discloses a ventilation, noise reduction and pressure relief integrated device suitable for intelligent substations, including a substation body; a temperature sensor is installed at the top inside the substation body, and an external heat dissipation module is fixedly installed at the rear end of the substation body; a heat dissipation groove is opened on the box door, and a sound insulation plate is installed at the bottom of the box door; a heat dissipation device is installed at the rear end of the external heat dissipation module, and a perforated heat dissipation plate is fixedly installed on the surface of the heat dissipation device.

[0005] The aforementioned application document describes a method that detects when the internal temperature of a substation reaches a predetermined threshold. It describes a system that uses a cooling device to circulate the coolant efficiently and uniformly, along with a spiral cooling pipe. This allows the coolant to remain within the spiral pipe for an extended period. Additionally, a circulating fan on a perforated cooling plate further enhances the airflow within the substation for heat dissipation. However, the heat dissipation effect is generally limited. Over time, the coolant temperature rises, affecting subsequent cooling performance. Furthermore, the overall system increases electricity consumption, making it less environmentally friendly.

[0006] To address the shortcomings of existing technologies, this invention provides a noise reduction and cooling environmental protection device for smart grid substations based on intelligent control. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a noise reduction and cooling environmental protection device for smart grid substations based on intelligent control, which solves the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A noise reduction and cooling environmental protection device for a smart grid substation based on intelligent control includes a base, a substation main body mounted on top of the base, an inspection door at the front end of the substation main body, a top cover fixedly connected to the top of the substation main body, a solar photovoltaic module mounted on the top of the top cover, and a heat dissipation mechanism at the rear end of the substation main body. The heat dissipation mechanism includes a mounting box and a temperature sensor. The mounting box is fixedly connected to the rear end of the substation main body, and heat-conducting fins are fixedly connected to the front end of the mounting box. Ventilation openings are provided on the sides of the mounting box, and dustproof nets are installed inside the ventilation openings. A mounting cylinder is fixedly connected to the inner wall of the mounting box, and a cooling motor is installed inside the mounting cylinder. A rotating shaft is fixedly connected to the output shaft of the cooling motor, and a cooling fan is fixedly connected to the end of the rotating shaft away from the cooling motor. The temperature sensor is fixedly mounted on the inner wall of the mounting box.

[0009] According to the above technical solution, a total of seven sets of heat-conducting fins are set, and the front ends of the seven sets of heat-conducting fins penetrate through the main body of the substation. The heat can be transferred from the main body of the substation into the installation box through the heat-conducting fins.

[0010] According to the above technical solution, a battery is installed inside the solar photovoltaic module, and the cooling motor is electrically connected to the battery through a wire. The cooling motor is also electrically connected to the PLC controller through a wire. The solar photovoltaic module converts solar energy into electrical energy and stores it in the battery. The battery powers the cooling motor. When the temperature sensor detects that the temperature is high, it transmits a signal to the PLC controller through a wire. The PLC controller intelligently controls and starts the cooling motor.

[0011] According to the above technical solution, a cleaning mechanism is provided at the end of the cooling fan away from the shaft. The cleaning mechanism includes a rotating cylinder and a rotating rod. The rotating cylinder is fixedly connected to the end of the cooling fan away from the shaft. A thermal expansion airbag is provided inside the rotating cylinder. The rotating rod passes through and is rotatably connected to the side of the dustproof mesh. A brush is fixedly connected to the side end of the rotating rod.

[0012] According to the above technical solution, the end of the rotating rod away from the brush is located inside the rotating drum, and the thermal expansion airbag is initially in a contracted state. When the thermal expansion airbag expands due to heat, it will squeeze and clamp the end of the rotating rod located inside the rotating drum.

[0013] According to the above technical solution, a circulating water cooling mechanism is provided at the bottom of the mounting box. The circulating water cooling mechanism includes a water storage tank, a bevel gear A, a vertical rod, a pressure chamber, and a circulation pipe. The water storage tank is located at the top of the base and has a grid plate inside. The bevel gear A is fixedly connected to the surface of the rotating shaft. The vertical rod passes through and is rotatably connected to the bottom of the mounting cylinder. The top of the vertical rod is fixedly connected to a bevel gear B, and the bottom of the vertical rod is fixedly connected to a cam. The pressure chamber is fixedly connected to the bottom of the mounting box and has a return spring inside. A piston rod is slidably connected to the pressure chamber through the return spring piston. A water suction pipe passes through and is fixedly connected to the bottom of the pressure chamber, and a water delivery pipe passes through and is fixedly connected to the top of the pressure chamber. Both the water suction pipe and the water delivery pipe have one-way valves inside. The circulation pipe passes through and is fixedly connected to the heat-conducting fins.

[0014] According to the above technical solution, the end of the piston rod away from the return spring is close to the cam, and a ball is provided at the end of the piston rod away from the return spring. When the cam rotates with the vertical rod, it will repeatedly squeeze the piston rod. The rolling of the ball can reduce the wear on the piston rod.

[0015] According to the above technical solution, the one-way valve inside the suction pipe is unidirectionally open to the inside of the pressure chamber. The end of the suction pipe away from the pressure chamber is connected to the water storage tank and fixedly connected. When a negative pressure is formed inside the pressure chamber, water will be drawn from the water storage tank through the suction pipe.

[0016] According to the above technical solution, the end of the water supply pipe away from the pressure chamber is connected to the circulation pipe and fixedly connected. The one-way valve in the water supply pipe is unidirectionally open to the circulation pipe. When the water in the pressure chamber is squeezed, the water in the pressure chamber will be transported to the circulation pipe through the water supply pipe.

[0017] According to the above technical solution, the end of the circulation pipe away from the water supply pipe is connected to the water storage tank and fixedly connected. The end of the suction pipe away from the pressure chamber is equipped with a filter screen. The water in the circulation pipe can flow back into the water storage tank, and the filter screen can prevent debris from entering the suction pipe.

[0018] This invention provides a noise reduction and cooling environmental protection device for smart grid substations based on intelligent control. It has the following beneficial effects: (1) By setting up a heat dissipation mechanism, the heat inside the substation body can be introduced into the mounting box through the heat-conducting fins and discharged through the ventilation on both sides of the mounting box when the internal temperature is high. When the internal temperature is high, the PLC controller will intelligently control the start of the cooling motor to drive the rotating shaft to rotate. The battery in the solar photovoltaic module provides power. The rotation of the rotating shaft drives the cooling fan to rotate. The rotation of the two sets of cooling fans with different air directions makes a single-direction air duct formed in the mounting box, thereby improving heat dissipation. The overall heat dissipation effect is good and it is green and environmentally friendly.

[0019] (2) The present invention enables the cooling motor to start and drive the rotating shaft to rotate. During the process of the rotating shaft driving the cooling fan to rotate for heat dissipation, if the temperature inside the installation box continues to rise, the dust filter will be cleaned by the cooperation of components such as the thermal expansion airbag and the rotating rod, so as to prevent the heat dissipation from being affected by the blockage of the dust filter.

[0020] (3) By setting up a circulating water cooling mechanism, when the cooling motor is turned on and drives the rotating shaft to rotate, the water suction pipe will draw water from the water storage tank through the cooperation of components such as bevel gear A, bevel gear B, and pressure chamber, and then transport the water to the circulation pipe through the water delivery pipe. Finally, the water will flow back to the water storage tank through the circulation pipe. Rainwater can replenish the water storage tank. The water in the water storage tank near the ground will circulate into the circulation pipe and carry away the heat in the installation box and the heat-conducting fins, further improving the heat dissipation effect.

[0021] (4) The substation body 2, maintenance door 3, and top cover 4 of the present invention are all made of foam sandwich panel color steel tile. The foam sandwich panel color steel tile is provided with foam core material inside. The foam core material is filled with a large number of tiny pores. When sound waves (air vibration) are introduced, they will reduce the reflection and propagation of sound, and have the function of noise reduction. The inner and outer surfaces of the foam sandwich panel color steel tile are coated with polyurethane rigid foam, which has the functions of insulation and fireproofing. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0025] A noise reduction and cooling environmental protection device for a smart grid substation based on intelligent control includes a base 1, a substation body 2 on the top of the base 1, an inspection door 3 at the front end of the substation body 2, a top cover 4 fixedly connected to the top of the substation body 2, a solar photovoltaic module 5 (conventional technology) on the top of the top cover 4, and a heat dissipation mechanism 6 at the rear end of the substation body 2.

[0026] The substation main body (2), inspection door (3), and roof (4) are all constructed using foam-core sandwich panel corrugated steel sheets. These sheets contain a foam core material filled with numerous tiny pores, which reduces sound reflection and propagation when sound waves (air vibrations) enter, thus providing noise reduction. Both the inner and outer surfaces of the foam-core sandwich panel corrugated steel sheets are coated with rigid polyurethane foam, providing insulation and fire resistance.

[0027] The heat dissipation mechanism 6 includes a mounting box 61, a temperature sensor 69, and a PLC controller. The mounting box 61 is fixedly connected to the rear end of the substation body 2. A heat-conducting fin 62 is fixedly connected to the front end of the mounting box 61. Seven sets of heat-conducting fins 62 are configured, with their front ends penetrating the substation body 2. The heat-conducting fins 62 can transfer heat from the substation body 2 into the mounting box 61. A ventilation opening 63 is provided on the side of the mounting box 61, and a dustproof mesh 64 is installed inside the ventilation opening 63. A fixed connection is made to the inner wall of the mounting box 61. The system includes an installation cylinder 65, inside which is a cooling motor 66. The output shaft of the cooling motor 66 is fixedly connected to a rotating shaft 67. A cooling fan 68 is fixedly connected to the end of the rotating shaft 67 furthest from the cooling motor 66. A temperature sensor 69 is fixedly mounted on the inner wall of the installation box 61. The solar photovoltaic module 5 contains a storage battery (other components such as the charge / discharge controller are conventional technologies and will not be described in detail). The cooling motor 66 is connected to a PLC controller via wires, and the storage battery electrically powers both the cooling motor 66 and the PLC controller. The principle is as follows: the solar photovoltaic module 5 converts solar energy into electrical energy and stores it in the storage battery. The storage battery powers the cooling motor 66, the PLC controller, and the temperature sensor 69. When the temperature sensor 69 detects a high temperature, it transmits a signal to the PLC controller via wires. The PLC controller then intelligently controls and activates the cooling motor 66 (the combination of the PLC controller and the temperature sensor has intelligent control functionality, which is conventional technology and will not be described in detail).

[0028] In use, the heat from the substation main body 2 is transferred to the mounting box 61 through the heat-conducting fins 62, and then dissipated through the ventilation openings on both sides of the mounting box 61. The dustproof net 64 prevents dust and debris from entering and adhering to the heat-conducting fins 62, thus affecting heat dissipation. The solar photovoltaic module 5 converts solar energy into electrical energy and stores it in the battery, which powers the cooling motor 66. When the temperature sensor 69 detects a high temperature, it transmits a signal to the PLC controller via a wire. The PLC controller intelligently controls and turns on the cooling motor 66. The cooling motor 66 drives the rotating shaft 67 to rotate through its output shaft. The rotating shaft 67 drives the cooling fan 68 to rotate. The rotation of the cooling fan 68 generates airflow. The different blade angles of the two cooling fans 68 on both sides create different airflow directions. The rotation of the two sets of cooling fans 68 with different airflow directions creates a unidirectional airflow channel within the mounting box 61, thereby improving heat dissipation. The overall heat dissipation effect is good and environmentally friendly. When the temperature sensor 69 detects a low temperature, it transmits a signal to the PLC controller via a wire. The PLC controller intelligently controls and turns off the cooling motor 66. Example 2

[0029] A blockage-clearing mechanism 7 is provided at the end of the cooling fan 68 away from the shaft 67. The blockage-clearing mechanism 7 includes a rotating cylinder 71 and a rotating rod 73. The rotating cylinder 71 is fixedly connected to the end of the cooling fan 68 away from the shaft 67. A thermal expansion airbag 72 is provided inside the rotating cylinder 71. The rotating rod 73 passes through and is rotatably connected to the side of the dust filter 64. A brush 74 is fixedly connected to the side end of the rotating rod 73. The end of the rotating rod 73 away from the brush 74 is located inside the rotating cylinder 71. The thermal expansion airbag 72 is initially in a contracted state. When the thermal expansion airbag 72 expands due to heat, it will squeeze and clamp the end of the rotating rod 73 located inside the rotating cylinder 71.

[0030] During use, as the cooling fan 68 rotates, the temperature inside the mounting box 61 continues to rise. At this time, the thermal expansion airbag 72 expands due to heat and squeezes and clamps one end of the rotating rod 73 located inside the rotating cylinder 71. The rotation of the cooling fan 68 drives the rotating cylinder 71 to rotate, and the rotation of the rotating cylinder 71 drives the rotating rod 73 to rotate through the expanded thermal expansion airbag 72. The rotation of the rotating rod 73 drives the brush 74 to rotate, and the rotation of the brush 74 cleans the surface of the dust filter 64 to prevent the dust filter 64 from being blocked and affecting heat dissipation. Example 3

[0031] The bottom of the mounting box 61 is equipped with a circulating water cooling mechanism 8, which includes a water storage tank 81, a bevel gear A83, a vertical rod 84, a pressure chamber 87, and a circulation pipe 813. The water storage tank 81 is located at the top of the base 1, and a grid plate 82 is installed inside the water storage tank 81. The bevel gear A83 is fixedly connected to the surface of the rotating shaft 67. The vertical rod 84 passes through and is rotatably connected to the bottom of the mounting cylinder 65. The top of the vertical rod 84 is fixedly connected to a bevel gear B85, and the bottom of the vertical rod 84 is fixedly connected to a cam 86. The pressure chamber 87 is fixedly connected to... Located inside the bottom of the mounting box 61, the pressure chamber 87 contains a return spring 88. A piston rod 89 is slidably connected to the pressure chamber 87 via the return spring 88. The end of the piston rod 89 furthest from the return spring 88 is close to the cam 86, and a ball bearing 810 is located at the end of the piston rod 89 furthest from the return spring 88. When the cam 86 rotates with the vertical rod 84, it repeatedly presses against the piston rod 89. The rolling of the ball bearing 810 reduces wear on the piston rod 89. A suction device is fixedly connected through and to the bottom of the pressure chamber 87. Water pipe 811 and pressure chamber 87 are connected by a water supply pipe 812 through and fixedly connected to each other. Both the suction pipe 811 and the supply pipe 812 are equipped with one-way valves. The one-way valve in the suction pipe 811 allows unidirectional flow into the pressure chamber 87. The end of the suction pipe 811 away from the pressure chamber 87 is connected to the water storage tank 81 through and fixedly connected to it. When a negative pressure is created inside the pressure chamber 87, water is drawn from the water storage tank 81 through the suction pipe 811. Circulation pipe 813 is connected to the heat-conducting fins 62 through and fixedly connected to it. The supply pipe 812 is located away from the pressure chamber 87. One end of the water supply pipe 812 is connected to the circulation pipe 813 and fixedly connected. The one-way valve in the water supply pipe 812 is unidirectionally open to the circulation pipe 813. When the water in the pressure chamber 87 is squeezed, the water in the pressure chamber 87 will be transported to the circulation pipe 813 through the water supply pipe 812. The end of the circulation pipe 813 away from the water supply pipe 812 is connected to the water storage tank 81 and fixedly connected. The end of the suction pipe 811 away from the pressure chamber 87 is equipped with a filter screen. The water in the circulation pipe 813 can flow back into the water storage tank 81. The filter screen can prevent debris from entering the suction pipe 811.

[0032] In use, the top of the water storage tank 81 protrudes above the ground, while its bottom is underground. Rainwater can be stored in the water storage tank 81. The grating plate 82 can prevent debris from entering. When the cooling motor 66 drives the rotating shaft 67 to rotate, the rotation of the rotating shaft 67 will drive the bevel gear A83 to rotate, the rotation of bevel gear A83 will drive the rotation of bevel gear B85, the rotation of bevel gear B85 will drive the vertical rod 84 to rotate, and the rotation of the vertical rod 84 will drive the cam 86 to rotate. The rotation of the cam 86 will repeatedly squeeze the piston rod 89 to move it into the pressure chamber 87. The return spring 88 will be compressed. When the cam 86 squeezes the piston rod 89, it will contact the ball bearing 810. The rolling of the ball bearing 810 will reduce the friction and delay the piston rod. The wear of piston rod 89 causes the piston rod 89 to move into pressure chamber 87, which in turn squeezes the water in pressure chamber 87. This causes the water in pressure chamber 89 to be transported to circulation pipe 813 through water supply pipe 812. The water in circulation pipe 813 flows back to water storage tank 81 from the other end. When cam 86 leaves piston rod 89, return spring 88 rebounds and drives piston rod 89 to move out of pressure chamber 87. At this time, negative pressure is formed in pressure chamber 87, which draws water from water storage tank 81 through water suction pipe 811 to replenish the pressure chamber 87. This cycle continues, and the cooler water in water storage tank 81 near the ground circulates into circulation pipe 813 to carry away the heat from mounting box 61 and heat-conducting fins 62, further improving the heat dissipation effect.

[0033] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
