[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0019] Please refer to Figures 1-4 The embodiment provides a waterproof structure for a long-focus camera pod of an unmanned aerial vehicle, which comprises a pod bottom plate 1, a ring 2, a plurality of screw hole columns 3, two supports 4 and a pod cover 5. A lens port is formed in the center of the pod bottom plate 1. The ring 2 is arranged on the outer side of the pod bottom plate 1 and corresponds to the lens port. The ring 2 can protect the lens. When not in use, a lens protection cover can be covered on the lens. A ladder groove 1a is arranged on the edge of the inner side of the pod bottom plate 1 close to the lens port. A sealing washer is arranged in the ladder groove 1a.

[0020] The camera is usually difficult to fix in the narrow space without support, and is fixed in the pod through the support 4 to avoid displacement to cause the image shot to be not clear and accurate. The screw hole columns 3 are fixed on the inner side of the pod bottom plate 1 and located on both sides of the lens port. The one side of the two supports 4 is arranged on both sides of the lens port and fixed on the screw hole columns 3. The distance between the screw hole columns 3 and the lens port is adjustable, so that the support 4 does not affect the rotation of the focusing ring and the aperture ring on the camera lens. The other side of the two supports 4 is fixed on both sides of the camera, so that the lens of the camera is embedded in the stepped groove 1a. The waterproof is realized through the stepped groove 1a and the sealing pad to avoid water entering the inside of the pod to damage the internal instruments. The mounting hole on the side close to the camera of the support 4 is a waist hole. If the camera is telescopic, the design of the waist hole can also realize fine adjustment, which is more convenient. The pod cover 5 is fixed on the pod bottom plate 1.

[0021] In addition, the waterproof groove is arranged on the edge of the pod bottom plate 1. The waterproof groove is located on the inner side of the pod bottom plate 1 and the inner wall is provided with a waterproof pad. The sealing strip 5a which can be embedded in the waterproof groove is arranged on the side of the pod cover 5 close to the pod bottom plate 1, so as to avoid water entering the inside of the pod through the gap between the pod bottom plate 1 and the pod cover 5 to damage the instruments.

[0022] In order to further prevent water from entering the gap between the pod bottom plate 1 and the pod cover 5, the mounting plate 6 is arranged. The mounting plate 6 is arranged on the outer side of the pod cover 5 close to the pod bottom plate 1 and adjacent to the sealing strip 5a. The mounting plate 6 includes a mounting surface and a waterproof surface. The cross section of the mounting plate 6 is L-shaped. One side of the mounting surface is fixed on the pod cover 5. The waterproof surface is arranged on the other side of the mounting surface. The pod cover 5 is fixed on the pod bottom plate 1 through the mounting surface, so that the waterproof surface wraps the pod bottom plate 1 to avoid water entering the gap between the pod bottom plate 1 and the pod cover 5.

[0023] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
