Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem of poor sealing between the generator set's enclosure and door, which prevents waterproofing and thus makes the generator set unusable outdoors in rainy weather, this invention provides a waterproof structure, a generator set door frame, and a generator set. This structure utilizes a sealing component to block the leakage gap, preventing rainwater from entering the door frame along the gap. Simultaneously, the sealing component creates a water-guiding gap connected to the leakage gap, allowing rainwater entering the gap to flow along this gap, thus preventing rainwater from entering the door frame and affecting the normal operation of the generator set, thereby providing waterproofing.

[0027] Please see Figure 1 , Figure 4 , Figures 1 to 4 This is a schematic diagram of a waterproof structure, a generator door frame, and a generator unit according to an embodiment of the present invention. The waterproof structure is configured to connect to the generator door frame, which includes a door frame 100 and a door 200. An installation opening 110 is formed on one side of the door frame 100, and the door 200 is embedded in the installation opening 110. A water leakage gap 120 is formed between the circumferential side wall of the door 200 and the circumferential inner wall of the installation opening 110. The waterproof structure includes at least one sealing component 400, which is connected to the door frame 100 and configured to seal against the door 100 when the door 200 is closed. The sealing component 400 forms a water guiding gap 430, which is arranged along the circumference of the door 200 and communicates with the water leakage gap 120.

[0028] In this device, compared to the prior art, a sealing component 400 is provided relative to the leakage gap 120 to block the leakage gap 120, preventing rainwater from entering the door frame 100 along the leakage gap 120. At the same time, the sealing component 400 can form a water guiding gap 430 connected to the leakage gap 120, allowing rainwater entering the leakage gap 120 to flow along the water guiding gap 430, preventing rainwater from entering the door frame 100 and affecting the normal use of the generator set, thus enabling it to have a waterproof function. This solves the technical problem in the prior art where the poor sealing between the generator set's enclosure and the enclosure door 200 results in a lack of waterproof effect, thus preventing the generator set from being used outdoors in rainy weather.

[0029] Further, in the present device, the door frame 100 is a six-sided hollow frame structure. One side is the installation opening 110, and the other three sides, the top surface, and the bottom surface are all formed into a sealed housing structure by welding. This is a conventional setting well-known to those skilled in the art and will not be elaborated further here.

[0030] In this embodiment, as Figure 2 shown, the present device further includes a connecting body 300. The connecting body 300 is in the shape of a "square", and the circumferential side wall of the connecting body 300 is connected to the circumferential inner wall of the installation opening 110. The number of sealing components 400 is four. The connecting body 300 extends into the door frame 100. The four first connecting parts 410 are evenly distributed around the connecting body 300 and are all connected to the connecting body 300, and the adjacent two first waterproof parts 420 are in sealed contact with each other.

[0031] The four inner side walls of the installation opening 110 are all provided with first waterproof parts 420, thereby increasing the sealing and waterproof effect.

[0032] Further, the water guiding gap 430 is annular and is connected to the four water leakage gaps 120 formed between the circumferential side wall of the box door 200 and the circumferential inner wall of the installation opening 110. The rainwater collected at the top and on both sides flows into the water guiding gap 430 and then flows along the annular water guiding gap 430 and is concentrated at the bottom of the door frame 100 and flows out from the water leakage gap 120 at the bottom of the door frame 100, which can effectively prevent rainwater from entering the door frame 100 and affecting the normal operation of the generator set.

[0033] In one of the embodiments, please refer to Figures 2 to 4 , the sealing component 400 further includes a second connecting part 440. One end of the second connecting part 440 is connected to the other end of the first connecting part 410, and the other end is connected to the first waterproof part 420. The second connecting part 440 and the first connecting part 410 and the first waterproof part 420 enclose to form the water guiding gap 430.

[0034] The first waterproof part 420 and the first connecting part 410 are parallel to each other and spaced apart, and form an integral body through the second connecting part 440.

[0035] Further, the first waterproof part 420, the second connecting part 440, and the first connecting part 410 are connected in sequence and form an inturned edge waterproof structure similar to a "J" shape, which can block the water leakage gap 120 and block the rainwater, preventing rainwater from entering the door frame 100 along the water leakage gap 120.

[0036] In one of the embodiments, as Figure 4As shown, a first rounded chamfer 450 is formed at the connection between the first connecting part 410 and the first waterproof part 420, and a second rounded chamfer 460 is formed at the connection between the second connecting part 440 and the first connecting part 410 and the first waterproof part 420.

[0037] The first rounded chamfer 450 and the second rounded chamfer 460 are respectively set at the connection, which can guide rainwater to flow better along the guide gap 430, avoid structural corrosion caused by rainwater in the water guide gap 430, and improve the waterproof sealing effect.

[0038] In one embodiment, please refer to Figure 4 The sealing assembly 400 also includes a second waterproof part 470, which is parallel to and spaced apart from the first connecting part 410. One end of the second waterproof part 470 is connected to the door 200, and the other end can extend and be built into the water guiding gap 430.

[0039] The second waterproof part 470 is connected to the door 200 and can extend into the water guiding gap 430. It is used to guide the rainwater that enters the leakage gap 120 and adheres to the inner wall of the door 200 to flow along the guide of the second waterproof part 470, thereby improving the waterproof sealing effect.

[0040] In one embodiment, please refer to Figure 4 The sealing assembly 400 also includes a third connecting part 480, one end of which is connected to one end of the second waterproof part 470 and the other end is connected to the door 200, and the length of the third connecting part 480 is greater than the distance between the first waterproof part 420 and the door 200.

[0041] The third connecting part 480 is used to connect the second waterproof part 470 and the door 200, and to allow the extension direction of the second connecting part 440 to be built into the water guide gap 430.

[0042] In one embodiment, such as Figure 4 As shown, the connection between the third connecting part 480 and the box door 200 and the second waterproof part 470 is respectively formed with a third rounded chamfer 490.

[0043] The third rounded chamfer 490 is set at the connection point, which can guide rainwater to flow better along the guide gap 430, avoid structural corrosion caused by rainwater in the guide gap 430, and improve the waterproof sealing effect.

[0044] In one embodiment, please refer to Figure 4The sealing assembly 400 also includes a sealing strip 500, which is disposed between the door 200 and the first waterproof part 420. One end of the sealing strip 500 is bonded to the first waterproof part 420 and the other end abuts against the door 200.

[0045] A sealing strip 500 is placed between the first waterproof part 420 and the door 200 to enhance the sealing and waterproofing effect.

[0046] Furthermore, the sealing strip 500 here is a common and readily available device on the market, and is a standard feature known to those skilled in the art, so it will not be described in detail here.

[0047] This utility model also proposes a unit door frame, including a door frame 100, a box door 200 and a waterproof structure as described above. A mounting opening 110 is formed on one side of the door frame 100, and the box door 200 is embedded in the mounting opening 110.

[0048] A waterproof structure is installed at the connection between the door frame 100 and the box door 200 to block and seal the leakage gap 120 between the circumferential side wall of the box door 200 and the circumferential side wall of the installation opening 110 of the door frame 100, so as to prevent rainwater from entering the door frame 100 along the leakage gap 120.

[0049] Furthermore, the door frame 100 is a six-sided hollow frame structure, with one side having an installation opening 110. The other three sides, top surface, and bottom surface are all welded to form a sealed shell structure. The door 200 is also equipped with a door lock, which can engage with the door frame 100 to achieve a detachable connection between the door 200 and the door frame 100. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0050] This utility model also proposes a generator set, including a generator and a unit door frame as described above, wherein the generator is built into the door frame 100 and connected to the door frame 100.

[0051] The door frame 100, the box door 200, and the waterproof structure form a sealed shell structure. The generator is built into the box, which can achieve the effects of sealing and waterproofing and reducing noise.

[0052] Furthermore, the composition of the generator here is a conventional setup known to those skilled in the art, and will not be described in detail further.

[0053] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0054] At least one sealing component 400 is connected to the door frame 100 via a connector 300. A first connecting portion 410 is parallel to and spaced apart from the leakage gap 120, and is connected to the connector 300. A first waterproof portion 420 is parallel to and spaced apart from the first connecting portion 410, and is connected to the first connecting portion 410, forming a water-guiding gap 430 communicating with the leakage gap 120. Compared to the prior art, by setting the first connecting portion 410 relative to the leakage gap 120, the leakage gap 120 is sealed, preventing rainwater from entering the door frame 100 along the leakage gap 120. Simultaneously, the first waterproof portion 420 connected to the first connecting portion 410 forms a water-guiding gap 430 communicating with the leakage gap 120, allowing rainwater entering the leakage gap 120 to flow along the water-guiding gap 430, preventing rainwater from entering the door frame 100 and affecting the normal operation of the generator set, thus providing waterproof functionality.

[0055] In the specific working process of this utility model, when the generator set is used outdoors and encounters rain or snow, rainwater enters through the water leakage gap 120 between the door 200 and the door frame 100. It first flows through the surface of the second waterproof part 470 and enters the water guiding gap 430. Then, the rainwater entering the top and sides of the door 200 will converge at the bottom of the door 200 and flow out of the water guiding gap 430 along the surface of the second waterproof part 470 located at the bottom of the door 200, effectively achieving a sealing and waterproof effect.

[0056] This device, through the aforementioned structure, can solve the technical problem in the prior art where the poor sealing between the generator set's housing and the door 200 results in a lack of waterproofing, thus preventing the generator set from being used outdoors in rainy weather.

[0057] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
