DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] See also Figures 1 to 5 , This embodiment provides a technical solution: an electrical automation control cabinet for a thermal power plant, comprising a cabinet 1, wherein a heat dissipation mechanism is provided inside the cabinet 1 for dissipating heat from the cabinet 1;

[0025] A waterproof mechanism, installed at the lower end of the cabinet 1, for waterproofing the cabinet 1;

[0026] The driving mechanism is installed at the lower end of the waterproof mechanism and is used to drive the waterproof mechanism.

[0027] More specifically, when the cabinet 1 is working, the internal heat is used to dissipate the heat of the cabinet 1 through the heat dissipation mechanism; the water vapor entering the lower end of the cabinet 1 is waterproofed by the waterproof mechanism; the waterproof mechanism is driven and controlled by the driving mechanism to complete the lifting and lowering to play a waterproof role.

[0028] It is worth noting that: the heat dissipation mechanism works through a heat exchange mechanism to transfer the heat in the cabinet to the external environment. The heat exchange module can use a heat sink, a fan or other heat-conducting materials to increase the heat exchange area inside and outside the cabinet. For example, fans can be used to accelerate the dissipation of heat by forcing air flow. The fan extracts the hot air in the cabinet 1 and introduces cold air from the outside, thereby reducing the temperature in the cabinet. The heat dissipation mechanism is also equipped with a temperature sensor to monitor the temperature in the cabinet in real time. When it is detected that the temperature exceeds the preset threshold, the fan or other heat dissipation device is automatically started to keep the temperature in the cabinet within a safe range. In addition, heat pipe technology can also be used, and the heat pipe can quickly transfer heat from the high temperature area to the low temperature area, thereby effectively dissipating heat. The waterproof mechanism prevents moisture from entering the cabinet 1 through a sealing design. The waterproof mechanism allows the accumulated water inside to be discharged while preventing external water from entering. The outer wall of the cabinet 1 adopts a waterproof material, such as a waterproof coating or a waterproof film, to enhance the waterproof performance of the cabinet 1. The lower end of the cabinet 1 is equipped with a water level sensor. When it is detected that the water level in the cabinet 1 reaches a certain height, the drainage system of the waterproof mechanism is automatically started to waterproof. The driving mechanism can drive the waterproof mechanism to seal the lower end of the cabinet 1 so that the water outside the lower end will not continue to enter upward, and the accumulated water will be discharged from the cabinet. The driving mechanism is connected to the water level sensor and automatically starts or stops according to the feedback of the sensor. When the water level sensor detects that the water level is too high, the driving mechanism automatically starts to seal the lower end of the cabinet 1 for waterproofing. The driving mechanism includes an overload protection mechanism. When an abnormal load is detected, the system automatically cuts off the power supply to protect the entire driving system. The present invention ensures the stable operation of the cabinet 1 under various environmental conditions by integrating the heat dissipation mechanism, the waterproof mechanism and the driving mechanism, thereby preventing overheating and moisture intrusion, thereby improving the reliability and service life of the equipment.

[0029] Embodiment 2:

[0030] Based on the above embodiments:

[0031] Please refer to the accompanying drawings, the hemostasis assembly in the first embodiment is disclosed as follows: the cabinet 1 includes a cabinet door 2 installed on one side thereof, and the heat dissipation mechanism is installed at the inner upper end of the cabinet door 2.

[0032] Embodiment three:

[0033] Based on the above embodiments:

[0034] Please refer to the accompanying drawings, and the heat dissipation mechanism in Example 1 is disclosed as follows. The heat dissipation mechanism includes a heat exchange module 22, a heat dissipation channel 23, and a heat dissipation through hole 24. The heat exchange module 22 includes at least two groups of heat dissipation machines. The heat dissipation channel 23 is arranged in the right side wall of the cabinet 1, and the upper end tube passes through the inner wall of the cabinet 1 from the lower end of the outer wall of the cabinet 1, and the heat dissipation through hole 24 is arranged at the bottom of the cabinet 1.

[0035] More specifically, these heat dissipation machines can be fans, heat sinks or other types of heat exchange devices. Their main function is to absorb the heat in the cabinet and transfer it to the heat dissipation channel. Each group of heat dissipation machines is designed with a specific heat exchange area and heat exchange efficiency to ensure that heat can be effectively absorbed from the equipment in the cabinet; the heat dissipation channel 23 is set in the right side wall of the cabinet 1. It is a pipe structure, the upper end starts from the outer wall of the cabinet 1, and the lower end runs through the inner wall of the cabinet 1. The design of this channel allows the heat in the heat exchange module to be guided to the outside of the cabinet, thereby realizing the transfer and dissipation of heat; the heat dissipation holes 24 are set at the bottom of the cabinet 1. They are a series of small holes for guiding the hot air in the cabinet 1 to the external environment. When the fan or heat sink in the heat exchange module 22 transfers the heat to the heat dissipation channel, the heat will flow through the heat dissipation channel 23 with the air flow, and finally be discharged from the cabinet 1 through the heat dissipation holes 24. The design of the heat dissipation holes 24 must ensure sufficient ventilation area to achieve effective heat exchange, and prevent the excessive aperture from causing other components in the cabinet 1 to be invaded by dust or moisture. The entire system is designed to effectively discharge the heat in the cabinet 1 through heat conduction and convection, so as to keep the equipment in the cabinet running at a suitable temperature, extend the service life of the equipment and ensure its stability.

[0036] Embodiment 4:

[0037] Based on the above embodiments:

[0038] Please refer to the accompanying drawings, and the waterproof mechanism in Example 1 is disclosed as follows: the waterproof mechanism includes a water baffle 14 and a first sealing component. The water baffle 14 is arranged on the inner side of the lower end of the cabinet body 1 and the cabinet door 2, and the edge of the water baffle 14 is close to the inner wall of the cabinet body 1 and the cabinet door 2. The first sealing component is arranged on both sides of the inner wall of the cabinet body 1, and the second sealing component is provided at the upper and lower ends of both sides of the water baffle 1.

[0039] It is worth noting that the waterproof mechanism also includes a first sealing strip 11 and a second sealing strip 21. The first sealing strip 11 is installed on the cabinet body 1, and the second sealing strip 21 is installed on the cabinet door 2. The first sealing strip 11 is concave in the middle, and the second sealing strip 21 is convex in the middle, which can match and engage during sealing to achieve a better sealing effect.

[0040] More specifically, the upper end of the heat dissipation channel 23 starts from the outer wall of the cabinet 1 and the lower end penetrates into the inner wall of the cabinet 1, and is located at the lower end of the water baffle 14. When blocking water, the water will be blocked at the lower end of the water baffle 14 and will not pass through the heat dissipation channel 23 to enter the interior of the cabinet 1 upward. Any water accumulated at the bottom of the cabinet 1 will be blocked at the lower end of the water baffle 14, preventing the water from passing through the heat dissipation channel 23 to enter the interior of the cabinet 1 upward. The water baffle 14 is the main component of the waterproof mechanism. It is arranged on the inner side of the lower end of the cabinet 1 and the cabinet door 2 and is in direct contact with and close to the inner wall of the cabinet door 2 when the cabinet door 2 is closed, forming a physical barrier to prevent moisture from entering the internal space from the bottom of the cabinet 1. The first sealing component is arranged on both sides of the inner wall of the cabinet 1 and is used in conjunction with the water baffle 14 to enhance the waterproof effect. To ensure that there is no gap at the connection between the cabinet 1 and the cabinet door 2 to prevent moisture from penetrating. The second sealing component is arranged at the upper and lower ends of both sides of the water baffle 14 to further enhance the sealing performance of the waterproof mechanism. To ensure that the connection between the water baffle 14 and the cabinet 1 and the cabinet door is also sealed. The first sealing strip 11 is installed on the cabinet 1, and the second sealing strip 21 is installed on the cabinet door 2. When the cabinet door 2 is closed, the two strips can be snapped together to form a tight seal to improve the waterproof effect. When the cabinet 1 and the cabinet door 2 are closed, the water baffle 14, the first sealing assembly, the second sealing assembly, and the first sealing strip 11 and the second sealing strip 21 work together to form a complete waterproof barrier. The water baffle 14 prevents moisture from entering from the bottom of the cabinet, while the sealing assembly and the sealing strip ensure that there is no gap at the connection between the cabinet and the cabinet door to prevent moisture penetration. Since the water baffle 14 is located at the lower end of the heat dissipation channel 23, even if water accumulates at the bottom of the cabinet, it will be blocked by the water baffle 14 and will not enter the interior of the cabinet through the heat dissipation channel 23, thereby protecting the equipment in the cabinet from moisture damage.

[0041] Embodiment five:

[0042] Based on the above embodiments:

[0043] Please refer to the accompanying drawings, and the first sealing component in Example 1 is disclosed as follows: the first sealing component includes a first sealing plate 17 and a second sealing plate 26. Both sides of the cabinet body 1 are respectively provided with an embedding groove 16. The first sealing plate 17 and the second sealing plate 26 are respectively installed at the upper and lower ends of the embedding groove 16. A first sealing plug 18 is installed on one side of the lower end of the first sealing plate 17, and a first sealing groove 25 is provided at the upper end of the second sealing plate 26.

[0044] More specifically, when the first sealing plate 17 or the second sealing plate 26 contacts the water retaining plate 14, they form a sealed space. Figure 4-5The embedded groove 16 shown in the figure is in a cross-section shape. The embedded groove 16 cannot be seen from this angle from a normal perspective. The height of the embedded groove 16 is greater than the water baffle 14 to provide space for it to adjust up and down. Both ends of the embedded groove 16 extend toward the inner wall of the cabinet 1, so the two sides of the water baffle 14 do not contact it. A space is formed when there is no contact. This space is used for air circulation. When the water baffle 14 is located in the middle of the height of the embedded groove 16, the space of the cabinet 1 at the upper and lower ends of the water baffle 14 can be circulated through this space for air to achieve the effect of heat and moisture removal.

[0045] Embodiment six:

[0046] Based on the above embodiments:

[0047] Please refer to the accompanying drawings, and the second sealing assembly in Example 1 is disclosed as follows: the second sealing assembly includes a second sealing plug 20 and a second sealing groove 19. The second sealing plug 20 is installed on both sides of the lower end of the water retaining plate 14, and the second sealing groove 19 is arranged on both sides of the upper end of the water retaining plate 14. The second sealing plugs 20 are the same in number and in corresponding positions as the first sealing grooves 25, and the second sealing grooves 19 are the same in number and in corresponding positions as the first sealing plugs 18.

[0048] More specifically, the second sealing plugs 20 and the first sealing grooves 25 are the same in number and in corresponding positions, and can achieve a sealing effect when engaged; the second sealing grooves 19 and the first sealing plugs 18 are the same in number and in corresponding positions, and can achieve a sealing effect when engaged.

[0049] During specific implementation, the lower end of the driving mechanism is fixed to the inner wall of the cabinet 1 through a connecting plate. The driving mechanism includes a cylinder 13. The specific use position of the water baffle 14 is controlled by the output and retraction of the cylinder 13. There can be at least three positions. First, the water baffle 14 is in contact with the first sealing plate 17 upward for sealing; second, the water baffle 14 is in contact with the second sealing plate 26 downward for sealing; third, the water baffle 14 is in the middle of the embedded groove 16 without being sealed, and the space reserved at both ends of the embedded groove 16 is used for air flow in the cabinet 1.

[0050] More specifically, in the above embodiment, the temperature sensor causes a change in physical quantity according to the temperature change, and generates an electrical signal that can be used to reflect the temperature change. The temperature sensors include, for example, resistance sensors, thermocouples, and thermal resistors. Resistance sensor: A circuit composed of resistance elements, which change with the change of temperature. When the temperature rises, the resistance decreases, and when the temperature drops, the resistance increases. This change will generate a signal to reflect the temperature change. Thermocouple: The combination of two different conductors or semiconductors is called a thermocouple. The thermoelectric potential of a thermocouple is synthesized by the contact potential and the temperature difference potential. The potential generated at the contact point of two different conductors or semiconductors is related to the properties of the two conductors or semiconductors and the temperature at the contact point. Infrared temperature sensor: When the temperature of an object is higher than absolute zero, it will continuously radiate electromagnetic waves to the surroundings, including infrared rays with a wavelength of 0.75 to 100 μm. Infrared temperature sensors are made using this principle.

[0051] More specifically, in the above embodiments, the water level sensor relies on a series of physical or chemical principles to sense water in the environment. When water or water level changes are detected, the sensor generates an electrical signal or other form of output to trigger an alarm system, close a valve, start a pump system, or notify a user. Resistive water immersion sensor: Based on simple resistance detection, the basic circuit is based on Ohm's law, where voltage equals current multiplied by resistance. The electrodes emit a fixed-frequency AC waveform, and the resistance between the electrodes is calculated by detecting the amplitude of the waveform. When the resistance is lower than a certain threshold, it is determined that there is water and an alarm is triggered. Optical water immersion sensor: Determines the presence of water by detecting changes in the reflection and refraction conditions of light. When water covers the optical part of the sensor, the dielectric properties of water change the reflection and refraction conditions of light, resulting in significant changes in the intensity and path of light reaching the optical sensor. The circuit then converts this optical signal into an electrical signal to accurately indicate the presence or absence of water.

[0052] More specifically, in the above embodiment, a wind speed sensor is also included, and the wind speed sensor is used to measure the speed of air flow. They can be based on various principles, such as hot wire anemometer, pitot tube, ultrasonic wind speed sensor, etc. Hot wire anemometer: uses a heated metal wire as a sensing element. When air flows through the metal wire, it takes away heat, causing the temperature of the metal wire to drop. By measuring the change in the temperature of the metal wire, the wind speed can be calculated. Ultrasonic wind speed sensor: By transmitting and receiving ultrasonic pulses, the time difference of ultrasonic waves propagating in the air is measured, thereby calculating the wind speed.

[0053] More specifically, in the above embodiment, the magnetic switch (for the cylinder) is usually composed of a magnetic sensing device (sensor) and a trigger. The trigger can detect the change of the magnetic field near the magnetic sensing device, and when the trigger receives the signal of the magnetic field change, it will output an electrical signal. When the piston moves to a specific position inside the cylinder, a magnetic body will be placed on the cylinder. Through the action of the magnetic field, the trigger can detect the position of the magnetic body and output an electrical signal. These sensors work together to ensure the stable operation of the electrical automation control cabinet of the thermal power plant under various environmental conditions, prevent overheating and moisture intrusion, and improve the reliability and service life of the equipment.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
