[0032] like Figure 1-5As shown, this embodiment provides an electrical component mounting plate 15, including a plate body 21, a water retaining portion and a first connecting portion 26. The plate body 21 is configured in a rectangular shape, and has a plurality of mounting holes on the plate body 21, wherein the plurality of mounting holes at least include a first mounting hole 211 for mounting a controller 30 and a second mounting hole 212 for mounting an air circuit breaker assembly 40. The four sides of the plate body 21 are bent downward to form a plurality of water retaining portions, wherein the water retaining portions include a first water retaining portion 22 and a second water retaining portion 23 respectively located at the front and rear ends of the plate body 21, and a third water retaining portion 24 and a fourth water retaining portion 25 respectively located at the left and right sides of the plate body 21. A first connecting portion 26 is respectively provided at both ends of the right side of the plate body 21, and the first connecting portion 26 is coplanar with the plate body 21, and a first through hole 261 for screws to pass through is provided on the first connecting portion 26, thereby realizing that the entire electrical component mounting plate 15 is fixed to other structural parts.

[0033] In this embodiment, the electrical component mounting plate 15 (i.e., the top plate referred to in the background technology of this application) is structurally improved, that is, the four sides of the plate body 21 are bent downward to form a plurality of water retaining portions. When water on the upper surface of the plate body 21 flows downward through the four sides of the plate body 21, it is difficult for the water to flow to the bottom surface of the plate body 21 due to the obstruction of the water retaining portions. In addition, there is a certain distance between the four sides of the plate body 21 and the mounting holes on the plate body 21, and the electrical components themselves have a certain degree of waterproofness. Therefore, comprehensively speaking, the risk of short circuiting of the electrical components due to water flowing downward from the top surface of the electrical component mounting plate 15 is reduced.

[0034] It should be noted that the various electrical components installed in the mounting holes will be sealed between the mounting holes themselves, such as by setting sealing rings. Therefore, the possibility of water on the top surface of the plate body 21 flowing into the electrical components through the mounting holes is very low. The present application is mainly an improved design for possible water leakage around the plate body 21.

[0035] In one embodiment, since the controller 30 is installed in the first mounting hole 211, in order to facilitate the user to control the generator set, the controller 30 usually needs to be arranged in the front, so the first mounting hole 211 is arranged near the front end of the plate body 21. The lower end of the first water retaining portion 22 has a drainage groove 221 formed by bending upward from the bottom of the first water retaining portion 22. The water flowing downward from the front end of the top surface of the plate body 21 is guided to one or both of the left and right sides through the drainage groove 221 at the lower end of the first water retaining portion 22, thereby further reducing the possibility of water flowing into the controller 30, and thus the controller 30 can be better protected from water.

[0036] In one embodiment, the left end of the drainage groove 221 extends to the left to the outside of the third water retaining portion 24, and the right end of the drainage groove 221 is higher than the left end of the drainage groove 221. Through such an arrangement, the water flow in the drainage groove 221 can be introduced to the outside of the third water retaining portion 24, and in the generator set, the outside of the third water retaining portion 24 is located in the cooling chamber where the engine and the generator are installed. Therefore, introducing the water flow into the cooling chamber can prevent the water flow from flowing downward into the electrical chamber 16, thereby causing hidden dangers to other electronic components in the electrical chamber 16.

[0037] In one embodiment, the front and rear ends of the third water retaining portion 24 are respectively connected to the first water retaining portion 22 and the second water retaining portion 23 by welding. Since the first water retaining portion 22, the second water retaining portion 23 and the third water retaining portion 24 are all bent downward from the plate body 21, there will be gaps between the front and rear ends of the third water retaining portion 24 and the first water retaining portion 22 and the second water retaining portion 23, respectively. Eliminating the gap by welding can, on the one hand, prevent water from flowing through the gap into the bottom surface of the plate body 21, and on the other hand, improve the overall strength of the plate body 21.

[0038] In one embodiment, the first mounting hole 211 and / or the second mounting hole 212 are arranged near the left side of the plate body 21, specifically, at least one of the first mounting hole 211 and the second mounting hole 212 is arranged near the left side of the plate body 21. Since the first connecting portion 26 is arranged at the front and rear ends of the right side of the plate body 21, the existence of the first connecting portion 26 will reduce the length of the fourth water retaining portion 25, and there will inevitably be a gap between the front and rear ends of the fourth water retaining portion 25 and the two first connecting portions 26. Therefore, through the above arrangement, the controller 30 and / or the air circuit breaker assembly 40 will be relatively far away from the fourth water retaining portion 25, so that the risk of the controller 30 and / or the air circuit breaker being short-circuited by water flowing through the gap is reduced.

[0039] In one embodiment, a generator box is provided, including a base 10, a front support plate 11, a front panel (not shown in the drawings), a rear support plate 12, a right side plate 13, a partition 14 and an electronic component mounting plate, wherein the electronic component mounting plate is a structure provided by any of the above embodiments. The front support plate 11 is arranged on the right side of the front end of the base 10, the rear support plate 12 is arranged on the right side of the rear end of the base 10, the right side plate 13 is arranged on the right side of the base 10, the partition 14 is arranged on the base 10 and is located on the left side of the right side plate 13, and the electrical component mounting plate 15 is arranged on the top of the front support plate 11 and the rear support plate 12. The base 10, the front support plate 11, the front panel, the rear support plate 12, the right side plate 13, the partition 14 and the electronic component mounting plate enclose an electrical cavity 16 in which electronic components are installed. The second water retaining portion 23 in the electrical component mounting plate 15 is located at the rear end of the rear support plate 12, and the third water retaining portion 24 is located at the left side of the partition plate 14, that is, the electrical component mounting plate 15 covers the top of the rear support plate 12 and the partition plate 14, so that the water flowing downward through the second water retaining portion 23 and the third water retaining portion 24 will not flow into the electrical cavity 16. Generally, the front panel and the right side panel 13 are detachable for the purpose of inspection and maintenance, so the electrical component mounting plate 15 does not cover the top of the front panel and the right side panel 13.

[0040] In one embodiment, the air circuit breaker assembly 40 includes a housing 41 and an air circuit breaker 42 disposed in the housing 41. The upper end of the housing 41 is connected to the electrical component mounting plate 15. The left side of the housing 41 is open, and the left side of the housing 41 at least partially maintains a certain distance from the partition 14. The housing 41 is open to reduce the material consumption, and the purpose of maintaining a certain distance between the left side of the housing 41 at least partially and the partition 14 is to further reduce the possibility of water flowing into the housing 41.

[0041] In one embodiment, the rear end of the left side of the housing 41 is provided with a second connection portion 411 bent downward from the end of the left side of the housing 41, and the second connection portion 411 is provided with a second through hole 412 for a screw to pass through and connect with the partition 14. The connection strength of the housing 41 can be enhanced by providing the second connection portion 411. The housing 41 has a bottom surface for mounting the air circuit breaker arranged in a transverse direction, and the bottom surface is located above the second connection portion 411. Such an arrangement can further reduce the possibility of water flowing into the housing 41 and causing the air circuit breaker in the housing 41 to short-circuit.

[0042] In one embodiment, the plate body 21 is provided with a third through hole 213 for screws to pass through and connect with the rear support plate 12 and the partition 14, and the first water retaining portion 22 is provided with a fourth through hole 222 for screws to pass through and connect with the front support plate 11 and the partition 14. This arrangement facilitates the connection between the electrical component mounting plate 15 and other components in the generator set case, thereby improving the structural stability and connection reliability of the generator set case.

[0043] In one embodiment, a generator set is provided, comprising the generator set box provided by any one of the above embodiments.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
