Description

Technical Field

[0001] This utility model relates to a protection device for power equipment, and more particularly to a safety protection device for power terminal equipment. Background Technology

[0002] Power terminal equipment plays a crucial role in power transmission and distribution. To ensure the normal operation of this equipment, protective enclosures or rooms are usually installed outside the equipment to prevent rainwater corrosion and electric shock accidents. However, to ensure continuous heat dissipation of the equipment, these protective enclosures or rooms usually have ventilation holes on the sides. While this design solves the heat dissipation problem to some extent, it also introduces a series of new safety hazards.

[0003] For example, dust and fine particles can more easily enter the enclosure. Dust accumulation not only clogs ventilation holes, affecting heat dissipation, but can also cause short circuits or fires due to localized high temperatures caused by dust buildup. Furthermore, ventilation holes provide entry points for insects such as mosquitoes. These insects may carry flammable materials such as hay and down into the enclosure. If these flammable materials ignite due to high temperatures during equipment operation, it will pose a serious threat to the safety of the entire power system. Therefore, designing a power terminal protection device that can effectively dissipate heat while preventing the entry of dust and insects has become an urgent problem to be solved in the field of power equipment protection. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a safety protection device for power terminal equipment, which can not only effectively solve the heat dissipation problem, but also prevent the intrusion of dust and insects.

[0005] The technical implementation scheme of this utility model is as follows: a safety protection device for power terminal equipment includes a base and a housing. The housing is installed on the upper side of the base. The left and right sides of the housing are sandwich structures, consisting of an inner layer, an outer layer, and a cavity between them. The front and bottom sides of the cavity are open. A guide channel communicating with the open is provided on the base. The guide channel extends through the rear side of the base. A cover plate is fastened to the front open of the cavity. The lower side of the inner layer is provided with a first ventilation opening communicating with the inside of the housing and the cavity. The upper side of the outer layer is provided with a second ventilation opening communicating with the outside and the cavity. A louver is installed on the first ventilation opening and the second ventilation opening respectively. A top cover is provided on the top of the housing. Rain collection channels are provided around the top cover. The rain collection channels and the guide channels are connected through guide pipes.

[0006] Optionally, the louvers at the first ventilation opening are dustproof louvers.

[0007] Optionally, the guide channel is inclined in a front-high-rear-low manner.

[0008] Optionally, the box is equipped with an insect repellent box, and the insect repellent box contains insect repellent tablets.

[0009] Optionally, a ventilation window is provided on the upper rear side of the housing, and a ventilation mechanism is installed at the ventilation window.

[0010] Optionally, the ventilation mechanism includes a ventilation fan and a fan housing. The fan housing is disposed on the outside of the ventilation window and covers the ventilation fan. Ventilation holes are provided on both sides of the bottom of the fan housing. An oblique guide strip is provided on the inner rear side of the fan housing, and the end of the guide strip is close to the ventilation hole.

[0011] Optionally, a filter plate is provided in the middle of the cavity, and one end of the filter plate is plugged into and installed on the cover plate.

[0012] Compared with existing technologies, this utility model has the following advantages: 1. The sandwich structure of the housing not only provides an effective airflow channel but also blocks incoming dust, causing it to fall along the bottom of the cavity into the guide channel. The louvers installed at the first and second ventilation openings further prevent the intrusion of dust and insects. The guide pipe can divert rainwater from the rain collection trough into the guide channel to wash away the dust. This device ensures ventilation while greatly limiting the entry of dust and insects, effectively protecting the safe operation of power terminal equipment.

[0013] 2. In addition, the dustproof louvers can effectively block the intrusion of dust, fine particles and insects, thereby ensuring air circulation while reducing the accumulation of dust inside the box.

[0014] 3. The guide channel of this utility model has an inclined design with the front higher than the back, which can effectively guide rainwater carrying dust to flow out quickly, ensuring that the internal environment of the box is dry and clean.

[0015] 4. Setting up insect repellent boxes and tablets can effectively control the invasion of insects and reduce the risk of insects breeding in the box.

[0016] 5. By installing ventilation windows and a ventilation mechanism on the rear side of the enclosure, the air circulation efficiency inside the enclosure can be improved, further enhancing the heat dissipation effect. At the same time, the fan casing and air guide strips work together to guide the internal hot air out of the enclosure. The angled air guide strips help guide the airflow away from the bottom of the fan casing and reduce dust entering the enclosure through the ventilation windows.

[0017] 7. The filter plates effectively filter the air entering the cavity, blocking larger dust particles and dead leaves, ensuring cleaner air enters the chamber. This design not only reduces the risk of dust accumulation but also facilitates cleaning by maintenance personnel, and the plug-in design allows for regular filter plate replacement.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figure 1 , 2The power terminal equipment safety protection device shown includes a base 1 and a housing 2. The housing 2 is installed on the upper side of the base 1. The left and right sides of the housing 2 are sandwich structures, which consist of an inner layer 3, an outer layer 4, and a cavity between them. The front and bottom sides of the cavity are open. The base 1 is provided with a guide channel 5 communicating with the opening. The guide channel 5 passes through the rear side of the base 1. A cover plate 6 is fastened to the front opening of the cavity. After removing the cover plate 6, it is convenient to clean the cavity. The lower side of the inner layer 3 is provided with a first ventilation opening 7 communicating with the inside of the housing and the cavity. The upper side of the outer layer 4 is provided with a second ventilation opening 7 communicating with the outside and the cavity. Two ventilation openings 8; the first ventilation opening 7 and the second ventilation opening 8 are each equipped with a louver, connecting the inside of the box to the outside through the first ventilation opening 7 and the second ventilation opening 8, with the cavity as an intermediate transition section. After dust and insects enter the cavity, due to the obstruction of the inner layer 3, they will enter the guide channel 5 along the bottom of the cavity. Their only channel into the box is the first ventilation opening 7, thus greatly reducing the probability of dust and insects entering the box. In addition, a top cover 9 is provided on the top of the box 2, which serves to protect against rain. Rain collection channels 10 are provided around the top cover 9, and the rain collection channels 10 are connected to the guide channel 5 through the guide pipe 11. On rainy days, rainwater enters the rain collection channel 10 along the top cover 9 and flows to the front end of the guide channel 5 through the guide pipe 11, carrying away the dust in the guide channel 5 as it flows to the rear end. The use of this utility model can reduce the entry of dust and insects into the box while ensuring ventilation, reducing potential threats and protecting the normal operation of the power terminal.

[0025] Specifically in this embodiment, such as Figure 3 As shown, the louvers at the first ventilation opening 7 are equipped with dustproof ventilation fans. When dust falls, the louvers prevent it from entering the box through the gaps. In addition, a filter plate 19 is installed in the middle of the cavity. One end of the filter plate 19 is plugged into the cover plate 6. In windy weather, some leaves and other debris may enter through the second ventilation opening 8. The filter plate 19 can prevent them from falling and clogging the guide channel 5.

[0026] Specifically, in this embodiment, the guide channel 5 is inclined in a front-high-back-low manner, which is conducive to the rapid discharge of rainwater.

[0027] In order to repel insects, an insect repellent box 12 is also provided inside the box. Insect repellent tablets are placed inside the insect repellent box 12. By placing insect repellent tablets, insects that have entered or are about to enter can be further repelled.

[0028] like Figure 2 and Figure 4As shown, to further improve heat dissipation, a ventilation window 13 is provided on the upper rear side of the enclosure 2, and a ventilation mechanism 14 is installed at the ventilation window 13. Specifically, the ventilation mechanism 14 includes a ventilation fan 15 and a fan housing 16. The fan housing 16 is located outside the ventilation window 13 and covers the ventilation fan 15. Ventilation holes 17 are provided on the bottom of both sides of the fan housing 16, and an oblique guide strip 18 is provided on the inner rear side of the fan housing 16. The end of the guide strip 18 is close to the ventilation hole 17.

[0029] The ventilation fan 15 is activated to expel the hot air from the box. After the hot air is expelled into the fan housing 16, it flows to both sides along the guide strip 18 and is discharged through the ventilation holes 17. The ventilation holes 17 are located at the bottom of both sides of the fan housing 16, which prevents dust from accumulating and reduces the amount of dust passing through. The fan housing 16 and the ventilation window 13 enter the box.

[0030] During exhaust, hot air flows out, creating a certain negative pressure inside the chamber. External cold air first enters the cavity through the second vent 8, simultaneously blowing off the dust on the inner wall of the cavity to prevent a large amount of dust from adhering to the inner wall of the cavity. Then, the air enters the chamber 2 through the first vent 7 and flows from bottom to top, providing good heat dissipation. During this process, some dust inside the chamber is also carried out through the ventilation window 13.

[0031] This utility model has a compact overall structure and is easy to install. It is suitable for various power terminal equipment. Its application not only has a good ventilation and heat dissipation effect, but also effectively prevents the intrusion of dust and insects; it can maintain the operational safety and stability of the equipment.

[0032] In addition, it should be noted that the ventilation fan 15 in this utility model integrates a control unit and a timing unit, which are used to control the start and stop of the ventilation fan 15 as well as the shutdown and running time. Furthermore, a temperature detection module can be installed inside the housing 2. The temperature detection module is electrically connected to the control unit. When the temperature inside the housing reaches a certain value, the control unit starts the ventilation fan 15 to dissipate heat.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
