Description

Technical Field

[0001] This invention belongs to the field of electricity cost budgeting, and specifically relates to an electricity cost budget management device. Background Technology

[0002] In the operation of power systems, power cost budget management is a core component for improving operational efficiency and optimizing resource allocation. Power cost budget management equipment, as a key carrier for realizing this process, is widely used in various substations, distribution rooms, and power dispatch centers. This type of equipment typically integrates the cost budget management module into a dedicated cabinet. The cabinet protects and integrates the internal electronic components and control modules, ensuring stable module operation to perform core functions such as power cost statistics, analysis, prediction, and control.

[0003] Currently, the design focus of most power cost budget management equipment cabinets on the market is on structural load-bearing, spatial layout, and basic protection. They do not pay enough attention to key protection requirements such as heat dissipation, dehumidification, and fire extinguishing during equipment operation. As a result, the equipment is susceptible to environmental factors and its own heat generation during long-term operation, leading to problems such as decreased operational stability, frequent failures, and even safety accidents. This seriously restricts the efficient implementation of power cost budget management.

[0004] The power cost budget management module generates heat continuously during operation. In addition, the cabinet usually adopts a relatively closed structure to ensure dustproof and protective performance. Existing cabinets are mostly equipped with simple ventilation holes or small cooling fans to dissipate heat. The heat dissipation structure is not reasonably designed, and heat is easy to accumulate inside the cabinet and cannot be quickly dissipated.

[0005] Furthermore, power cost budget management equipment is often deployed in scenarios such as power distribution rooms or underground substations. These environments experience significant humidity fluctuations, especially during the rainy season, in high-humidity areas, or when there are large temperature differences between day and night. Temperature differences easily form between the inside and outside of the cabinet, causing moisture in the air to condense inside. Existing cabinets lack dedicated and efficient dehumidification mechanisms, relying solely on sealing or simple moisture-absorbing materials for dehumidification. This results in poor dehumidification, and residual moisture inside the cabinet can corrode electronic components and circuit interfaces, leading to decreased insulation performance, poor contact, short circuits, leakage, and other faults. This can damage the cost budget management module and affect the normal operation of the equipment.

[0006] The power cost budget management equipment cabinet integrates multiple electronic modules and circuits. In the event of a fire caused by overheating, short circuits, or other reasons, the existing cabinet lacks a dedicated built-in fire suppression system, relying primarily on external fire suppression systems. However, external fire response is delayed, and the fire cannot be quickly located and contained in its early stages, easily leading to its expansion. This could not only completely destroy the cost budget management equipment and its internally stored data but also potentially trigger a chain reaction of fires in surrounding electrical equipment, causing significant economic losses and power outages. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention aims to provide a power cost budget management device. This device has excellent heat dissipation, strong dehumidification capabilities, and outstanding fire emergency response capabilities, thereby effectively meeting the power system's requirements for long-term, efficient, and safe operation of cost budget management equipment.

The cost budget management module includes a data acquisition module, a data preprocessing module, a budget calculation module, a budget analysis module, and a storage and communication module.

[0026] The top of cabinet 1 is also equipped with fire extinguishing components; temperature and humidity sensors are also installed inside cabinet 1. A heat dissipation exhaust vent 11 and a dehumidification exhaust vent 13 are arranged side-by-side on the upper side of cabinet 1. A first air vent switching assembly is installed inside cabinet 1 at the heat dissipation exhaust vent 11 and the dehumidification exhaust vent 13. A first fan 111 and a second fan are respectively installed at the heat dissipation exhaust vent 11 and the dehumidification exhaust vent 13. A dehumidifier 2 and a water storage tank 24 are installed on cabinet 1. The air inlet of dehumidifier 2 is connected to dehumidification exhaust vent 13 through a first air duct 21. A heat dissipation air inlet 12 and a dehumidification air inlet 14 are opened on the lower side of cabinet 1. The dehumidification air inlet 14 is connected to the air outlet of dehumidifier 2 through a second air duct 22. The drain outlet of dehumidifier 2 is connected to water storage tank 24 through a water pipe 23. A second air vent switching assembly is installed inside cabinet 1 at the heat dissipation air inlet 12.

[0027] The first air vent switching component and the second air vent switching component work together in conjunction. Specifically, the first air vent switching component includes a first turntable 41, on which are provided exhaust holes 411 that cooperate with the heat dissipation exhaust vent 11 and the dehumidification exhaust vent 13, as well as a first sealing position 412 and a second sealing position 413. The exhaust holes 411, the first sealing position 412, and the second sealing position 413 are arranged at an angle on the first turntable 41. The second air vent switching component includes a second turntable 42, on which are provided air inlets that cooperate with the heat dissipation air inlets 12, as well as a third sealing position 422 and a fourth sealing position 423. The air inlets, the third sealing position 422, and the fourth sealing position 423 are arranged at an angle on the second turntable 42. The first turntable 41 and the second turntable 42 have the same diameter, and both are equipped with sealing gaskets on the side near the inner wall of the cabinet 1. The sealing gaskets abut against the inner wall of the cabinet 1. The sealing gaskets and the cabinet 1 work together to effectively improve the sealing between the turntables and the cabinet 1 and prevent air leakage.

[0028] Both the first turntable 41 and the second turntable 42 are concentrically fixed with corresponding sprockets 44, and a chain is provided between the two sprockets 44. A motor 15 is provided outside the cabinet 1, and the output shaft of the motor 15 passes through the side wall of the cabinet 1 and is concentrically fixed to the second turntable 42.

[0029] In the normal operation ventilation and heat dissipation state of this application: the exhaust hole 411 on the first turntable 41 is aligned with the heat dissipation exhaust port 11, and the air inlet hole on the second turntable 42 is aligned with the heat dissipation air inlet 12. At this time, the first fan 111 at the heat dissipation exhaust port 11 is activated, and the outside air inlet heat dissipation air inlet 12 enters the cabinet 1 and is then discharged through the heat dissipation exhaust port 11, thus completing the ventilation and heat dissipation inside the equipment. Dehumidification operation status: When the humidity sensor detects that the humidity inside the cabinet 1 is too high, the control motor 15 drives the chain to rotate, which in turn drives the two turntables to rotate synchronously. The exhaust hole 411 on the first turntable 41 rotates to align with the dehumidification exhaust port 13, the first sealing position 412 rotates to the heat dissipation exhaust port 11 to block the heat dissipation exhaust port 11, and the third sealing position 422 on the second turntable 42 rotates to the heat dissipation air inlet 12 to block the heat dissipation air inlet 12. Then the dehumidifier 2 and the second fan at the dehumidification exhaust port 13 are activated, which in turn draws the air inside the cabinet 1 into the dehumidifier 2 through the dehumidification exhaust port 13 and the first air duct 21. After the air is dehumidified, it is sent back into the cabinet 1 through the second air duct 22 and the dehumidification air inlet 14 to complete the internal circulation of dehumidification. When the humidity sensor detects that the humidity has reached the standard, the dehumidifier 2 and the second fan stop operating, and the motor 15 flips to drive the two turntables to switch to the normal operation ventilation and heat dissipation state. Emergency fire extinguishing status: Both fans stop operating, motor 15 rotates, driving the first turntable 41 to rotate, rotating the first sealing position 412 and the second sealing position 413 to correspond to the dehumidification exhaust port 13 and the heat dissipation exhaust port 11 respectively, thereby sealing the two exhaust ports; the fourth sealing position 423 of the second turntable 42 rotates to the heat dissipation air inlet 12 to seal the heat dissipation air inlet 12, thereby completing the effective sealing of the cabinet 1 and preventing the thick smoke from spreading outward.

[0030] The fire extinguishing system includes a dry powder tank 31, an electrically controlled feed valve 32, a pressure sensor, a smoke sensor, and a fire-fighting electrically controlled air valve 33. The dry powder tank 31 is installed outside the cabinet 1, and its nozzle is connected to the fire extinguishing outlet at the top of the cabinet 1 via the electrically controlled feed valve 32. The pressure sensor and smoke sensor are installed inside the cabinet 1; the fire-fighting electrically controlled air valve 33 is installed at the fire exhaust outlet at the top of the cabinet 1.

[0031] When a fire occurs inside cabinet 1, the smoke sensor detects dense smoke and controls the two air vent switching components to switch to the aforementioned emergency fire extinguishing state, sealing the air inlet and outlet to prevent dense smoke from leaking out. Then, the electrically controlled feed valve 32 is activated, and the dry powder tank 31 sprays fire extinguishing dry powder into cabinet 1 for emergency fire extinguishing. The pressure sensor constantly monitors the pressure inside the cabinet, and when it exceeds the threshold, it controls the fire-fighting electrically controlled air valve 33 to open for intermittent exhaust to balance the air pressure inside the cabinet.

[0032] A filter assembly 5 is installed at the heat dissipation air inlet 12. The filter assembly 5 includes an air filter element 54, a fixed cylinder base 52, and a movable cylinder base 51. The fixed cylinder base 52 and the movable cylinder base 51 are semi-cylindrical designs arranged symmetrically at the top and bottom. The fixed cylinder base 52 is fixedly installed at the heat dissipation air inlet 12 outside the cabinet 1, and the movable cylinder base 51 is fixedly fixed to the fixed cylinder base 52 through the opening of the locking assembly. The fixed cylinder base 52 has a groove 521, and the movable cylinder base 51 has a protrusion 511 fixed therein, which is inserted into the groove 521. The locking assembly includes a locking bolt 53, which is threaded through the side of the fixed cylinder base 52, extends into the groove 521, and abuts against the protrusion 511.

[0033] The air filter element 54 of this application can effectively filter the air entering the cabinet 1, reducing the entry of dust, particulate matter and other impurities in the air into the cabinet 1 and affecting the operation of the hardware module. The locking bolt 53 and the protrusion 511 lock together, which can realize the quick disassembly and installation of the movable cylinder seat 51 and the fixed cylinder seat 52, making it convenient for the replacement and maintenance of the air filter element 54.

[0034] When using this invention, through the coordinated operation of the two air vent switching components, in the normal operation ventilation and heat dissipation state, the first fan 111 operates, and the heat dissipation air inlet 12 and heat dissipation air outlet 11 realize the ventilation and heat dissipation inside the cabinet; in the dehumidification operation state, the dehumidifier 2 and the second fan operate, the heat dissipation air inlet 12 and heat dissipation air outlet 11 are blocked, and the dehumidification air inlet 14 and dehumidification air outlet 13 are opened, realizing the internal air circulation of the cabinet 1 for rapid dehumidification; in the emergency fire extinguishing state, the corresponding air inlet and outlet are blocked, so that a relatively sealed space is formed inside the cabinet 1, and rapid fire extinguishing and rescue can be achieved in conjunction with the operation of the fire extinguishing components.
