[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in a power plant is a step-up substation, and its function is to step up the voltage of the electric energy generated by the generator and feed it into the high-voltage power grid.

[0003] Substations have strict requirements on the surrounding temperature, humidity and cleanliness. In order to ensure that the temperature and humidity of the equipment indoors in the substation meet the requirements for stable operation of the equipment and to dissipate the heat generated by the equipment indoors in a timely manner, heat dissipation vents need to be set. However, after long-term use of the existing heat dissipation vents, some dust or insects will enter the device through the ventilation windows, resulting in a reduction in the ventilation effect of the ventilation device and affecting the internal environment of the device, thereby affecting the normal ventilation of the substation equipment.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are used to illustrate and are not used to limit the utility model. In addition, in all embodiments, the same figure numbers represent the same elements.

[0026] like Figure 1 A rainproof and dustproof box-type substation is shown, comprising a bottom plate 7 and a box body 1. The box body 1 is fixedly connected to the top of the bottom plate 7, one end of the box body 1 is provided with an opening, a box door 5 is hinged on one side of the opening, and a rectangular lock hole 50 is provided in the middle position of the box door 5 away from the hinged end. A circle of sealing strips 51 is provided on the inner side of the box door 5. A lock handle 6 is fixedly connected to the middle position of the other side of the opening of the box body 1, and the lock handle 6 is a columnar structure with an arc in the middle, and the lock handle 6 and the lock hole 50 cooperate with each other.

[0027] As a further illustration of this example, rotating the door 5 allows the lock handle 6 to pass through the lock hole 50 on the door 5 , and then hanging a lock on the lock handle 6 can complete the locking of the door 5 .

[0028] The upper part of the box body 1 near the two sides of the box door 5 is provided with a heat dissipation port 2, which is a plurality of rectangular hole structures arranged in a linear array along the vertical direction. A snap-fit ​​frame 8 is provided around the internal heat dissipation port 2 of the box body 1, and the snap-fit ​​frame 8 includes an upper frame 80 and a lower frame 81. The upper frame 80 is fixedly connected to the inner wall of the box body 1, and the bottom of the lower frame 81 near one side of the box body is hinged to the box body 1 through a hinge 9. A snap-fit ​​groove 82 is provided inside the upper frame 80 and the lower frame 81, and buckles 83 are fixedly connected on both sides of the snap-fit ​​groove 82 of the lower frame 81, and the buckle 83 can be fixedly connected with the buckle groove 84 provided at the bottom of the upper frame 80.

[0029] The dustproof net 4 is detachably connected in the snap-fitting groove 82 of the snap-fitting frame 8. The dustproof net 4 includes a net frame 40 and a net body 41. The net body 41 is fixedly connected to the inside of the net frame 40. The net frame 40 cooperates with the snap-fitting grooves 82 in the upper frame 80 and the lower frame 81.

[0030] As a further illustration of this example, the dust screen 4 is inserted into the snap-fit ​​groove 82 from the bottom of the upper frame 80. The snap-fit ​​groove 82 on the upper frame 80 is consistent with the width of the screen frame 40 and fits tightly. The width of the snap-fit ​​groove 82 on the lower frame 81 is greater than the width of the screen frame 40, which can ensure that the screen frame 40 can enter the snap-fit ​​groove 82 on the lower frame 81 when the mold is closed upward. Then, the lower frame 81 is rotated upward by hand so that the buckles 83 at both ends of the lower frame 81 cooperate with the buckle grooves 84 of the upper frame 80 to fix the lower frame 81 to the upper frame 80. When the dust screen 4 is too dirty, the buckle can be pressed to rotate the lower frame 81 downward, so that the dust screen 4 can be cleaned or replaced.

[0031] A top cover 3 is fixedly connected to the top of the box body 1 . The top cover 3 is in a herringbone shape. The periphery of the top cover 3 extends out of the edge of the box body 1 . A water-blocking edge 30 is fixedly connected to the bottom of the top cover 3 around the periphery.

[0032] As a further illustration of this example, the top cover 3 can prevent rainwater from accumulating on the top of the box body 1, allowing the rainwater to fall and drain in time, and the periphery of the top cover 3 is fixedly connected with a water-repellent edge 30 to prevent rainwater from infiltrating and hanging on the edge of the top cover 3.

[0033] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above implementation measures. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
