Description

Technical Field

[0001] The invention belongs to the technical field of water drones, and in particular relates to a moisture-proof protective cover for a high-speed camera of a water drone. Background Art

[0002] During underwater drone flight tests, high-speed cameras are installed to record the flight process and analyze the drone's performance. However, the operating environment of underwater drones often exposes the camera to humidity, which can cause moisture to enter the camera's internal electronics and even cause mold on the lens, impacting the camera's performance. Therefore, designing a protective cover that can handle and protect the camera from moisture is crucial. Summary of the Invention

[0003] Purpose of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a moisture-proof protective cover for a high-speed camera of a water drone, which solves the problem in the prior art that high-speed cameras of a water drone are easily affected by moisture.

[0005] Inventive technical solutions

[0006] A moisture-proof protective cover for a high-speed camera used in an aquatic drone comprises an outer shell, a filter layer, and an inner lining layer. The filter layer is disposed between the outer shell and the inner lining layer, a moisture-absorbing layer is disposed between the filter layer and the outer shell, and both the inner and outer surfaces of the outer shell are coated with a moisture-proof coating. The inner lining layer comprises a fixed portion and a movable portion. The fixed portion is used to mount a high-speed camera, and the movable portion can be closed and opened to separate and connect the inner cavity of the inner lining layer with the moisture-absorbing layer. The bottom plate of the outer shell is also provided with a fan and an electric heating network. The electric heating network is disposed on the inner side of the fan and is connected to the inner cavity of the inner lining layer through ventilation holes when the movable portion is open, and is isolated when the movable portion is closed. The filter layer is fixed to the shell.

[0007] Furthermore, the inner lining layer is cylindrical, the fixed part is the lower semicircle, the movable part is the upper semicircle, the fixed part is double-layered, and an arc-shaped space that can accommodate the movable part is left between the double layers. The inner lining layer also includes a rotating disk, which is fixed to the movable part and slidably connected to the fixed part. The ventilation hole is provided on the rotating disk, and a flange is installed at the outer center of the rotating disk. A motor is installed on the flange, and the motor body is installed on the bottom plate of the outer shell.

[0008] Furthermore, there are four ventilation holes, and the ventilation holes are symmetrical with the projection center of the fan on the rotating disk.

[0009] Furthermore, correspondingly, the fan has 4 settings, and the electric heating network has 2 settings, wherein the fan at the electric heating network is an air supply fan, and the fan without the electric heating network is an exhaust fan.

[0010] Furthermore, an electrical box is also provided on the fixed portion, and the electrical box includes: a humidity sensor, a motor controller, a fan controller, an electric heating network controller and a processor, wherein the humidity sensor is connected to the processor to collect humidity data in the lining cavity and send it to the processor, the motor controller is connected to the processor to send forward and reverse start and stop instructions to the motor controller, the motor controller is connected to the motor to send forward and reverse start and stop signals to the motor and receive motor status information sent by the motor, the processor is connected to the fan controller to send start and stop instructions to the fan, and the fan The controller is connected to the fan and is used to send start and stop signals to the fan. The processor is connected to the electric heating network controller and is used to send power-on and power-off instructions to the electric heating network controller. The electric heating network controller is connected to the electric heating network and is used to send power-on and power-off signals to the electric heating network. The processor is used to receive the humidity data. When the humidity data is greater than a preset threshold, the processor sends start and power-on instructions to the motor controller, fan controller and electric heating network controller respectively. When the humidity data is less than or equal to the preset threshold, the processor sends stop and power-off instructions to the motor controller, fan controller and electric heating network controller respectively.

[0011] Furthermore, the moisture-proof coating is a nano moisture-proof coating.

[0012] Furthermore, the material of the moisture absorbing layer is water-absorbing resin.

[0013] The advantages of the present invention are as follows: by arranging a moisture-absorbing layer in the outer shell of the high-speed camera, excess moisture in the inner cavity of the lining layer (i.e., the surrounding environment of the camera) can be effectively absorbed therein, thereby ensuring the dryness of the surrounding environment of the camera; at the same time, by setting the moisture-absorbing material as a water-absorbing resin, it has very good water absorption performance, which can absorb water hundreds to thousands of times heavier than its own weight, and has excellent water retention performance. Once it absorbs water and expands to become a hydrogel, it is difficult to separate the water even under pressure, thereby ensuring the overall dryness and safety of the protective cover; by applying a nano-scale moisture-proof coating on the inner and outer surfaces of the outer shell, it can effectively avoid external rainwater and internal wall-attached condensation water, thereby allowing the moisture-absorbing layer to fully absorb, further ensuring the overall dryness of the protective cover.

DETAILED DESCRIPTION

[0031] The present invention is achieved through the following technical solutions.

[0032] Figure 1 Schematic diagram of the connection structure between the camera protection cover and the slide rail; Figure 2 This is a schematic diagram of the installation position of a one-view camera of the present invention; Figure 3 FIG. 1 is a schematic diagram of the installation position of another viewing angle camera of the present invention; FIG. Figure 1-3 As shown, the present invention is designed based on a sliding rail high-speed camera. In the figure, a protective cover is mounted on a sliding frame, which is slidably mounted on a slide rail 2 to control the high-speed camera's shooting freedom. The main unit 301 and lens 302 of the camera 3 are both located within the protective cover. Both the main unit and the lens are fixedly mounted on a camera mounting base 10.

[0033] Figure 4 This is a schematic diagram of the three-dimensional structure of the present invention from a front-end perspective; Figure 5 This is a schematic diagram of the three-dimensional structure of the present invention from a rear-end perspective; Figure 6 This is a schematic diagram of the arrangement structure of the outer shell 1, moisture absorbing layer, filter layer and lining layer of the present invention; Figure 7 Schematic diagram of the filter layer structure of the present invention; Figure 4-7 As shown, a moisture-proof protective cover for a high-speed camera of a water-based drone includes: an outer shell 1, a filter layer 4 and an inner lining layer 5, wherein the filter layer 4 is arranged between the outer shell 1 and the inner lining layer 5, and a moisture-absorbing layer is provided between the filter layer 4 and the outer shell 1, and the moisture-absorbing layer fills the entire interlayer space. Here, the moisture-absorbing layer is preferably a water-absorbing resin, which has excellent water absorption properties. It can absorb water hundreds to thousands of times its own weight and has excellent water retention properties. Once it absorbs water and expands to become a hydrogel, it is difficult to separate the water even under pressure, thereby ensuring the dryness and safety of the protective cover as a whole.

[0034] The inner and outer surfaces of the shell 1 are coated with a moisture-proof coating, preferably a nano-scale moisture-proof coating, which can effectively avoid external rainwater and internal wall-attached condensation water, allowing the moisture-absorbing layer to fully absorb and further ensure the overall dryness of the protective cover.

[0035] The inner lining 5 is cylindrical and includes: a fixed part 502 and a movable part 501, wherein the fixed part is the lower semicircle, the movable part is the upper semicircle, and the fixed part is double-layered, and an arc-shaped space is left between the double layers to accommodate the sliding of the movable part; the inner lining also includes a rotating disk 503, wherein the rotating disk is fixed to the movable part and is slidably connected to the fixed part through an arc-shaped slide groove; the movable part can be closed and opened, and is used to isolate and connect the inner cavity of the inner lining layer with the moisture-absorbing layer. A flange 504 is also installed at the center of the outer side of the rotating disk. The center of the flange is connected to the output shaft of the motor 6, which is used to provide driving force for the rotation of the rotating disk, that is, to provide power for the closing and opening of the movable part. The main body of the motor 6 is installed in the center hole of the bottom plate 102 of the outer shell.

[0036] The rotating disk also has ventilation holes 5031. The bottom plate of the housing is also equipped with a fan and an electric heating network. The electric heating network is located at the inner end of the fan. The fan is connected to the inner cavity of the lining layer through the ventilation holes when the movable portion is open and is blocked when the movable portion is closed. There are four ventilation holes 5031, correspondingly four fans and two electric heating networks. The fan at the electric heating network is a supply fan, while the fan without the electric heating network is an exhaust fan. The ventilation holes and the fan's projection on the rotating disk are centrally symmetrical. This ensures that when the movable portion is open to absorb moisture, the supply fan and the electric heating network simultaneously deliver hot air to the inner cavity to accelerate absorption by the moisture-absorbing layer, while the exhaust fan draws any moisture that has not been absorbed to the outside, further accelerating the drying efficiency of the inner cavity. When the movable portion is closed, the ventilation holes are moved downward and covered by the rotating disk, forming a sealed space with the inner cavity, ensuring the inner cavity is sealed at an appropriate humidity.

[0037] An electrical box 9 is also provided on the above-mentioned fixed part 502, which includes: a humidity sensor, a motor controller, a fan controller, an electric heating network controller and a processor, wherein the humidity sensor is connected to the processor for collecting humidity data in the lining cavity and sending it to the processor, the motor controller is connected to the processor for sending forward and reverse start and stop instructions to the motor controller, the motor controller is connected to the motor for sending forward and reverse start and stop signals to the motor and receiving motor status information sent by the motor, the processor is connected to the fan controller for sending start and stop instructions to the fan, the fan controller is connected to the fan for sending start and stop signals to the fan, the processor is connected to the electric heating network controller for sending power-on and power-off instructions to the electric heating network controller, the electric heating network controller is connected to the electric heating network for sending power-on and power-off signals to the electric heating network, and the processor is used to receive humidity data. When the humidity data is greater than a preset threshold, the processor sends start and power-on instructions to the motor controller, the fan controller and the electric heating network controller respectively. When the humidity data is less than or equal to the preset threshold, the processor sends stop and power-off instructions to the motor controller, the fan controller and the electric heating network controller respectively.

[0038] Through the setting of the electrical box, automatic control of the drying process can be achieved.

[0039] The scope of protection of the present invention is not limited to the above-described embodiments. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the scope of the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
