[0003] The outer shell of a prefabricated box-type substation is generally made of steel structure, which is required to have sufficient strength and good weather resistance; it can be heat-insulated and cold-insulated, and has fire-proof properties; at the same time, the power equipment inside the prefabricated box-type substation requires a dry and dust-free operating environment; since the heat and exhaust gas generated by the operation of the power equipment will affect the safe operation or reduce the performance of the equipment, the exhaust performance is an extremely important part of the prefabricated box-type substation.

[0004] The power exhaust system used in conventional substations usually installs fans or exhaust fans on the wall. However, with this technical solution, it is difficult to take into account both ventilation and protection levels. Generally, the protection level is poor or the rainproof performance is poor. In addition, since the exhaust structure of the box-type substation is equipped with a motor, the protection level and rainproof requirements of the exhaust window are more stringent. The existing exhaust structure is difficult to meet the requirements of the box-type substation. Utility Model Content

[0014] Furthermore, the protection part includes: a first waterproof plate, the first waterproof plate is vertically upward and connected to the upper eaves of the leaf piece;

[0015] A second waterproof board; the second waterproof board is vertically downward and connected to the lower edge of the leaf plate;

[0016] Among them, between two adjacent leaf sheets arranged in parallel up and down, the first waterproof plate located on the lower leaf sheet is higher than the second waterproof plate located on the upper leaf sheet, so as to prevent flat splashing water from passing through the ventilation window assembly.

[0017] Furthermore, the lower end of the second waterproof board is bent inwardly to form a double-bending layer, and the lower end of the double-bending layer is arc-shaped.

[0018] Furthermore, the housing is obliquely mounted on one side of the ventilation window outer frame so that the exhaust direction of the fan is parallel to the leaf plate.

[0041] See also Figure 1-Figure 3 The rainproof exhaust window includes: a ventilation window assembly 1 and a fan assembly 2; the ventilation window assembly 1 includes: a ventilation window outer frame 11 and leaves 12; wherein the ventilation window outer frame 11 is made of metal material, and its overall rectangular structure, the middle part of the ventilation window outer frame 11 is the exhaust port; the leaves 12 are strip-shaped structures, and its two ends are respectively fixed on the ventilation window outer frame 11, and multiple leaves 12 are arranged in parallel with each other in the ventilation window outer frame 11, and ventilation gaps are formed between adjacent leaves 12.

[0042] See also Figure 4 and Figure 5Furthermore, the inner edge of the leaf 12 is higher than the outer edge thereof, so that the two sides of the leaf 12 form an upper eave of the leaf and a lower eave of the leaf respectively, so that the leaf 12 is fixed on the outer frame 11 of the ventilation window at an angle of 45°. The inclined design allows the dripping water hitting the leaf 12 to slide down the inclined surface, so that the ventilation window has the rainproof performance of making the surface dripping water drip vertically and blocking the passage of 15° inclined dripping water; further, a protective part is provided at the edge of the leaf 12; the protective part includes: a first waterproof board 121 and a second waterproof board 122; the lengths of the first waterproof board 121 and the second waterproof board 122 match those of the leaf 12; wherein the first waterproof board 121 is vertically connected to the upper eave of the leaf, and the second waterproof board 122 is vertically connected to the lower eaves of the leaf piece downward, so that the cross-section of the leaf piece 12 is a Z-shaped structure; in the above technical scheme, between two adjacent leaf pieces 12 arranged in parallel up and down, the upper surface of the first waterproof plate 121 located at the lower leaf piece 12 is higher than the lower surface of the second waterproof plate 122 located at the upper leaf piece 12; adopting this technical scheme, the first waterproof plate 121 can prevent the dripping water hitting the leaf piece 12 from splashing to the rear, and the first waterproof plate 121 and the second waterproof plate 122 cooperate to make the leaf piece 12 in the ventilation window outer frame 11 continuous in the vertical direction, which can achieve the technical effect of blocking 60° water spray and preventing horizontal splashing, further enhance the waterproof ability of the ventilation window, so that it can reach the IPx4 waterproof level in the national recommended standard GB / T 4208-2017, and solve the technical problem of poor rainproof performance of the exhaust and heat dissipation structure in the prior art.

[0043] See also Figure 3 and Figure 4 , further, as a preferred embodiment of the present application, the ventilation window outer frame 11 is composed of an upper curved plate 111, a lower curved plate 112 and two side curved plates 113; the upper curved plate 111, the lower curved plate 112 and the side curved plates 113 are all U-shaped structures with folded edges; wherein, the length of the outer folded edge of the upper curved plate 111 is greater than the length of the inner folded edge thereof; the length of the inner folded edge of the lower curved plate 112 is greater than the length of the outer folded edge thereof; the lengths of the folded edges on both sides of the side curved plates 113 are consistent;

[0044] See also Figure 6 In the above technical solution, the height difference of the folded edges on both sides of the upper curved plate 111 matches the inclination angle of the leaf piece 12, so that the inner folded edge of the upper curved plate 111 is connected to the first waterproof plate 121 located at the top of the ventilation window assembly 1, and the outer folded edge of the upper curved plate 111 is connected to the second waterproof plate 122 located at the top of the ventilation window assembly 1; thereby, the gap between the leaf piece 12 and the upper curved plate 111 is closed to avoid the accumulation of water and dust, and at the same time, the ventilation window outer frame 11 is more beautiful;

[0045] See also Figure 7The folded edges on both sides of the lower curved plate 112 match the inclination angle of the leaf piece 12, so that the inner folded edge of the lower curved plate 112 is connected to the first waterproof plate 121 located at the bottom of the ventilation window assembly 1, and the outer folded edge of the lower curved plate 112 is in contact with the second waterproof plate 122 located at the bottom of the ventilation window assembly 1; in this technical solution, the height of the lower eave of the leaf piece 12 is not lower than the height of the outer folded edge of the lower curved plate 112; it is ensured that water can flow to the outside along the inclined surface of the leaf piece 12, rather than gathering in the groove formed by the leaf piece 12 and the folded edge of the lower curved plate 112.

[0046] See also Figure 5 Furthermore, the first waterproof plate 121 and the second waterproof plate 122 are respectively fixed on the folded edge of the side bending plate 113 to form a stable connection between the leaf 12 and the ventilation window outer frame 11; the lower end of the second waterproof plate 122 is bent inward to form a double bending layer 1221; with this technical solution, the lower end of the double bending layer 1221 is arc-shaped, and the water-attached rust-proof performance is better than that of the single-layer structure, which solves the problem that the coating of the processed section of the single-layer structure is easily damaged; the leaf 12 is Z-shaped and fixed between the first waterproof plate 121 and the second waterproof plate 122, so that the rigidity of the leaf 12 is enhanced, the mechanical collision level reaches I K10, and the reliability is significantly better than the aluminum blinds, ventilation windows, steel mesh ventilation windows, etc. in the industry solution, which solves the technical problem of poor strength of the ventilation and heat dissipation structure in the prior art.

[0047] See also Figure 1 and Figure 4 , further, the fan assembly 2 includes: a shell 21, a fan 22 and a protective mesh cover 23; wherein the shell 21 is a semi-enclosed box-shaped structure, which is located on the inner side of the ventilation window outer frame 11 and fixed on the ventilation window outer frame 11 to completely cover the exhaust port; the fan 22 is fixed on the surface of the shell 21 away from the ventilation window assembly 1 and is connected to the inside of the shell 21; using this technical method, when the fan 22 is working, the heat and exhaust gas in the substation cabin can be extracted from the cabin through the ventilation window assembly 1, and the temperature in the cabin can be kept stable, thereby ensuring the operating safety and performance reliability of the power equipment;

[0048] As a preferred embodiment of the present application, the housing 21 is a special-shaped box structure with a trapezoidal longitudinal section, which is fixed obliquely on the side curved plate 113 so that the exhaust direction of the fan 22 is parallel to the leaf 12, thereby minimizing the wind resistance of the fan 22 when it is working. This solution can effectively improve the exhaust efficiency of the fan assembly 2; it can be understood that, refer to Figure 7 The bottom end of the lower surface of the shell is higher than the upper surface of the first waterproof plate at the bottom of the ventilation window assembly to prevent a groove from being formed between the shell 21 and the first waterproof plate 121, causing rainwater to enter the shell and accumulate in the groove and be unable to be discharged, resulting in water accumulation.

[0049] In the above technical solution, the inner surface of the outer shell 21 is inclined after installation. With this technical solution, even if a small amount of rainwater passes through the ventilation window assembly 1 and enters the outer shell 21 at the rear, it can be blocked by the outer shell 21 and slide back along the inclined surface of the ventilation window assembly 1 and discharged from the cabin. The design of the outer shell 21 indirectly extends the inclined length of the lowest leaf 12 in the ventilation window assembly 1, increases the difficulty of rainwater entering the cabin, and further enhances the rainproof performance of the rainproof exhaust window.

[0050] Furthermore, the protective mesh cover 23 can be detachably installed at the air inlet of the fan 22. The protective mesh cover 23 can prevent foreign objects such as metal wires from entering the inside of the fan 22, and can also block large particles of dust from passing through. The detachable installation method can be a bolt connection, or a snap-on connection method. With this technical solution, when dust adheres to the surface of the protective mesh cover 23 and affects the ventilation performance, it can be easily removed for cleaning without having to replace the entire machine, thereby saving the cost of use.

[0051] The rainproof exhaust window provided in the present application strengthens the rigidity of the leaf 12 by arranging a double bending layer 1221 on one side of the leaf 12, thereby improving the structural strength of the ventilation window; and adopts a method of cooperating with the leaf 12 and the fan assembly 2 to improve the rainproof performance of the exhaust window while ensuring the ventilation effect, thereby solving the technical problems of poor protection level and poor rainproof performance of the exhaust window in the prior art, and being able to meet the exhaust protection needs of the box-type substation.
