Description

Technical Field

[0001] This utility model relates to the technical field of power load forecasting, and in particular to a short-term load forecasting device for smart grids. Background Technology

[0002] Power load forecasting refers to the process of estimating the load demand of the power system for a future period by analyzing historical load data, meteorological conditions, socio-economic factors, and using statistical methods and forecasting models. The forecast results can help power companies formulate power generation plans and dispatch strategies, ensure the stable operation of the power grid and the safety of power supply, and effectively reduce operating costs. Power load forecasting is divided into short-term, medium-term, and long-term forecasts, which are applicable to scenarios such as real-time dispatch and monthly or annual planning, respectively. It is a key link in power system planning and management. With the continuous development of technology, the requirements for forecasting devices are also increasing. Therefore, a short-term load forecasting device for smart grids is particularly needed.

[0003] However, existing short-term load forecasting devices in smart grids, although using water tanks and other components to cool and dampen internal parts through water circulation, require a large amount of electricity for cooling, and water circulation cooling increases the risk of leakage, thus affecting the normal use of the device.

[0004] To address the aforementioned issues, a search revealed that patent CN216527033U discloses a short-term load forecasting device for a smart grid.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See also Figure 1-5 The present invention provides a technical solution: a short-term load forecasting device for a smart grid, comprising a housing 1 and a heat dissipation mechanism 2, wherein a heat dissipation mechanism 2 is provided on one side of the surface of the housing 1 and a combination mechanism 3 is provided at one end of the housing 1;

[0027] The heat dissipation mechanism 2 includes a connecting groove 201, an integrated groove 202, a rotating groove 203, a support block 204, a fixing frame 205, a motor 206, bolts 207, a filter screen 208, a belt 209, and fan blades 210. The surface of the housing 1 has a connecting groove 201. An integrated groove 202 is formed on one side of the connecting groove 201, and a rotating groove 203 is formed at one end of the connecting groove 201. A support block 204 is fixedly connected to one end of the connecting groove 201. A fixing frame 205 is fitted inside the integrated groove 202. A motor 206 is fitted inside the rotating groove 203. Bolts 207 are threaded into the fixing frame 205. A filter screen 208 is installed inside the fixing frame 205. A belt 209 is fitted to one side of the motor 206. A fan blade 210... On the other side of 9, a fan blade 210 is fitted. Through the arrangement of connecting groove 201, integrated groove 202, rotating groove 203, support block 204, fixing frame 205, motor 206, bolt 207, filter screen 208, belt 209 and fan blade 210, the heat dissipation mechanism 2 is installed on one side of the housing 1 to help the device dissipate heat. The motor 206 drives the fan blade 210 to rotate through the belt 209 to realize air flow and remove the heat inside the housing 1. The filter screen 208 is located on the outside of the fan blade 210 and can filter dust or impurities in the air entering the housing 1 to prevent them from entering the housing 1 and affecting the operation of the device. The filter screen 208 is fixed to the fixing frame 205 by four sets of bolts 207 and installed in the integrated groove 202 for easy disassembly and cleaning.

[0028] Furthermore, a fan blade 210 is attached to one side of the support block 204. The fan blade 210 is set inside the connecting groove 201. Through the setting of the fan blade 210, the fan blade 210 is driven to rotate by the motor 206 through the belt 209, generating airflow to carry away the heat inside the housing 1. Through airflow, the temperature inside the housing 1 is effectively reduced, preventing the components from being damaged due to overheating, thereby ensuring the normal operation of the equipment. The fan blade 210 is not only used for heat dissipation, but also to maintain the air circulation inside the housing 1, avoid the stagnation of internal air, further improve the heat dissipation effect, and extend the service life of the equipment components.

[0029] Furthermore, four sets of bolts 207 are provided on the fixing frame 205. The fixing frame 205 is fixed inside the integrated groove 202 by the bolts 207. Through the setting of the bolts 207, the filter screen 208 is securely installed inside the fixing frame 205 and the fixing frame 205 is fixed inside the integrated groove 202. This ensures that the filter screen 208 will not shift or fall off when airflow passes through, thereby maintaining the effective filtration position of the filter screen 208 to ensure heat dissipation and dust prevention effects. At the same time, since the bolts 207 are detachable fasteners, it is convenient to remove and replace the filter screen 208. When the filter screen 208 needs to be cleaned or replaced, simply loosen the bolts 207 to easily remove the filter screen 208, simplifying maintenance operations and reducing maintenance difficulty and time costs.

[0030] Furthermore, the fixing frame 205 and the filter screen 208 are set on the outside of the housing 1. The filter screen 208 is set on the outside of the fan blade 210. By setting the filter screen 208, the filter screen 208 installed on the outside of the fan blade 210 can effectively filter dust, impurities and other particles in the air entering the housing 1, prevent them from entering the housing 1, protect the internal components from contamination or damage. At the same time, by blocking dust from entering the housing 1, the filter screen 208 keeps the area around the fan blade 210 and the motor 206 clean, prevents the accumulation of impurities from affecting the heat dissipation effect, ensures that the fan blade 210 can operate effectively and achieve continuous heat dissipation.

[0031] Furthermore, the main body of the motor 206 is mounted on the housing 1, and one side of the belt 209 is embedded inside the rotating groove 203. Through the arrangement of the motor 206 and the belt 209, the motor 206 is the power source of the fan blade 210 in the device. It converts electrical energy into mechanical energy through rotation, drives the belt 209 to drive the fan blade 210 to rotate, thereby generating airflow and completing the heat dissipation function. The belt 209 connects the motor 206 and the fan blade 210, and is used to transmit the rotational motion of the motor 206 to the fan blade 210. The belt 209 transmission structure is simple and stable in operation, and can effectively transmit the power of the motor 206, so that the fan blade 210 rotates at an appropriate speed to achieve efficient heat dissipation.

[0032] Furthermore, the combined mechanism 3 includes an integrated plate 301, a slide 302, a light 303, a pulley 304, a groove 305, a push-pull plate 306, a damping spring 307, and a damping ball 308. An integrated plate 301 is mounted on one side of the housing 1, and slides 302 are provided on both sides of the housing 1. A light 303 is mounted on one end of the integrated plate 301. A pulley 304 is fitted inside the slide 302, and grooves 305 are provided on both sides of the slide 302. 05. A push-pull plate 306 is fitted on the other side of the pulley 304. A damping spring 307 is connected to one end of the groove 305. A damping ball 308 is connected to the other side of the damping spring 307. Through the arrangement of the integrated plate 301, the slide 302, the lighting lamp 303, the pulley 304, the groove 305, the push-pull plate 306, the damping spring 307 and the damping ball 308, the combined mechanism 3 is used to realize the sliding, fixing and lighting functions of the internal components of the housing 1. The slide 302 is located on both sides of the housing 1, and a pulley 304 is embedded inside it. The pulley 304 is connected to the push-pull plate 306, so that the push-pull plate 306 can move smoothly in the slide 302. The slide 302 has grooves 305 on both sides. The grooves 305 contain damping springs 307 and damping balls 308. The damping balls 308 and the grooves 305 work together to form a damping structure, which can buffer the push-pull plate 306 when it moves to prevent impact caused by rapid sliding. The lighting lamps 303 are installed on the integrated plate 301 and distributed inside the housing 1 to provide uniform lighting for the internal components for observation and maintenance.

[0033] Furthermore, the dimensions of the damping ball 308 and the groove 305 are matched. The damping ball 308 and the groove 305 form a sliding structure through the damping spring 307. With the damping spring 307 connected between the groove 305 and the damping ball 308, the damping spring 307 can play a buffering role when the push-pull plate 306 moves. The elastic force of the damping spring 307 can absorb part of the impact force generated during the sliding process, preventing violent impact when the push-pull plate 306 slides quickly, protecting the slide groove 302 and the push-pull plate 306 structure, and extending their service life. At the same time, the damping ball 308 is embedded in the groove 305 to form a positioning structure, making the position of the push-pull plate 306 in the slide groove 302 more stable. Through the cooperation of the damping ball 308 and the groove 305, the push-pull plate 306 will pause slightly at each groove 305 position when sliding, which makes it convenient for the user to accurately position the push-pull plate 306 and avoid sliding too fast or positional deviation.

[0034] Furthermore, eight sets of grooves 305 are provided on one side of the slide groove 302. The grooves 305 are evenly distributed on the slide groove 302. Through the arrangement of the grooves 305, the grooves 305 are evenly distributed on both sides of the slide groove 302, which are used to fix and guide the position of the damping ball 308. The damping ball 308 is embedded in the groove 305, so that the push-pull plate 306 can pause slightly at each groove 305 position during the sliding process, thereby achieving stable positioning and making it convenient for the user to move the push-pull plate 306 to the desired position precisely.

[0035] Furthermore, the lighting lamps 303 are installed inside the enclosure 1. Nine sets of lighting lamps 303 are installed on the integrated plate 301 and are evenly distributed. By installing the lighting lamps 303 inside the enclosure 1 and distributing them on the integrated plate 301, a uniform light source is provided inside the enclosure 1. The distribution of multiple sets of lighting lamps 303 ensures that all areas inside the enclosure 1 can obtain good lighting effects, which is convenient for operation and inspection. At the same time, the lighting lamps 303 make it easier for staff to observe the status of the components inside the enclosure 1. When performing equipment inspection, cleaning or maintenance, it is easier to see the details and improve maintenance efficiency and accuracy.

[0036] Furthermore, the damping ball 308 is in contact with one side of the pulley 304. The pulley 304 forms a sliding structure with the slide groove 302 through the push-pull plate 306. With the setting of the pulley 304, the pulley 304 is embedded in the slide groove 302 and connected to the push-pull plate 306. By rotating, the sliding friction is reduced, so that the push-pull plate 306 can move more easily and smoothly in the slide groove 302, reducing sliding resistance and improving the smoothness of operation. At the same time, the presence of the pulley 304 makes the push-pull plate 306 move more smoothly in the slide groove 302, avoiding the jamming or shaking caused by direct friction. The rolling characteristics of the pulley 304 make the push-pull plate 306 maintain a consistent and stable sliding speed and direction in the slide groove 302.

[0037] Working principle: The heat dissipation mechanism 2 is installed on one side of the housing 1 to help the device dissipate heat. The motor 206 drives the fan blade 210 to rotate through the belt 209 to realize air flow and remove the heat inside the housing 1. The filter screen 208 is located on the outside of the fan blade 210 to filter dust or impurities in the air entering the housing 1 to prevent them from entering the housing 1 and affecting the operation of the device. The filter screen 208 is fixed to the fixed frame 205 by four sets of bolts 207 and installed in the integrated groove 202 for easy disassembly and cleaning. The combination mechanism 3 is used to realize the sliding, fixing and lighting functions of the internal components of the housing 1. The slide 302 is located on both sides of the housing 1, and a pulley 304 is embedded inside it. The pulley 304 is connected to the push-pull plate 306, so that the push-pull plate 306 can move smoothly in the slide 302. The slide 302 has grooves 305 on both sides. The grooves 305 contain damping springs 307 and damping balls 308. The damping balls 308 and the grooves 305 work together to form a damping structure, which can buffer the push-pull plate 306 when it moves to prevent impact caused by rapid sliding. The lighting lamps 303 are installed on the integrated plate 301 and distributed inside the housing 1 to provide uniform lighting for the internal components for observation and maintenance.
