Description

Technical Field

[0001] This utility model is a multispectral imaging device, belonging to the field of multispectral imaging technology. Background Technology

[0002] A multispectral camera is a type of camera that captures images of the same area at the same moment across multiple wavelengths. Common multispectral cameras come in single-lens and multi-lens versions.

[0003] Publication number CN218634085U mentions a multispectral camera with drop protection. It uses support springs to stabilize the camera body, preventing internal components and electronic devices from dislodging during drops. However, multispectral cameras are primarily used for low-altitude agricultural photography, and this protective measure is ineffective against drops from low altitudes. Furthermore, the lens is unprotected, leading to lens damage during drone crashes. Therefore, a multispectral camera device is urgently needed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multispectral camera device to solve the problems mentioned in the background. This invention designs an internal lens protection mechanism and an external protective airbag to protect the multispectral camera body without obstructing the lens during use, and to further protect the lens in case of a fall. This provides better protection for the multispectral camera during use and prevents damage from a fall when the drone is flying at low altitude.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multispectral imaging device, comprising a multispectral camera, a multispectral lens, an outer protective shell, an outer protective airbag, and an internal lens protection mechanism. The multispectral lens is mounted on the front end of the multispectral camera, the internal lens protection mechanism is mounted on the outer surface of the multispectral camera, the outer protective shell is mounted on the outer surface of the internal lens protection mechanism, and the outer protective airbag is mounted on the outer surface of the outer protective shell. The internal lens protection mechanism includes an inner fixing shell, a valve, a PLC controller, and a high-pressure gas tank. The multispectral camera includes a gyroscope, an accelerometer, an angle sensor, an airbag housing, and a lens protective airbag. Internal mounting shells are installed on the upper and lower surfaces of the multispectral camera. A high-pressure gas tank is mounted on the rear end face of the multispectral camera. A gyroscope, an accelerometer, and an angle sensor are mounted on the rear end face of the high-pressure gas tank. Two gas valves are installed on the left and right ends of the high-pressure gas tank. Airbag housings are installed on both sides of the two internal mounting shells. A lens protective airbag is installed inside each airbag housing.

[0006] Furthermore, airbag bolt holes are respectively opened on the surface of the outer protective airbag on the left and right end faces, and two fixing seats are respectively installed on the left and right end faces of the two inner fixing shells. The outer protective shell and the inner fixing shell are fixedly connected by the outer shell fixing bolts and the fixing seats. The outer shell fixing bolts are located inside the corresponding airbag bolt holes.

[0007] Furthermore, four vent pipes are installed on the side surface of the high-pressure gas tank. The high-pressure gas tank and the vent pipes are connected through a gas valve. The other end of the vent pipe passes through the rear end face of the corresponding airbag shell and is connected to the lens protection airbag.

[0008] Furthermore, the output terminal of the gyroscope is connected to the input terminal of the PLC controller, the output terminal of the accelerometer is connected to the input terminal of the PLC controller, the output terminal of the angle sensor is connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is connected to the input terminal of the air valve.

[0009] Furthermore, each of the inner fixing shells is equipped with a connecting plate on its side surface, and the two inner fixing shells are fixedly connected by the connecting plate and connecting bolts. Each airbag shell is equipped with two airbag fixing straps on its front end face.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a multispectral camera device. Because it incorporates an external protective shell, an external protective airbag, an internal fixing shell, a connecting plate, connecting bolts, an air valve, a PLC controller, a high-pressure gas tank, a ventilation pipe, a gyroscope, an accelerometer, an angle sensor, an airbag shell, and a lens protective airbag, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The design of an internal lens protection mechanism and an external protective airbag enables protection of the multispectral camera body without obstructing lens shooting during use. In the event of a fall, the lens is further protected. This provides better protection for the multispectral camera during use and prevents damage from falls during low-altitude drone flights.

[0018] Please see Figures 1-4This utility model provides a technical solution: a multispectral imaging device, including a multispectral camera 1, a multispectral lens 2, an outer protective shell 3, an outer protective airbag 4, and an internal lens protection mechanism 5. The multispectral lens 2 is mounted on the front end of the multispectral camera 1. The internal lens protection mechanism 5 is mounted on the outer surface of the multispectral camera 1.

The outer protective airbag 4 is mounted on the outer surface of the outer protective shell 3. The internal lens protection mechanism 5 includes an inner fixing shell 51, an air valve 52, a PLC controller 53, a high-pressure gas tank 54, a gyroscope 55, an accelerometer 56, an angle sensor 57, an airbag shell 58, and a lens protection airbag 59. The multispectral camera 1... An internal fixing shell 51 is installed on the upper and lower surfaces respectively. A high-pressure gas tank 54 is installed on the rear end face of the multispectral camera 1. A gyroscope 55 is installed on the rear end face of the high-pressure gas tank 54. An accelerometer 56 is installed on the rear end face of the high-pressure gas tank 54. An angle sensor 57 is installed on the rear end face of the high-pressure gas tank 54. Two gas valves 52 are installed on the left and right ends of the high-pressure gas tank 54 respectively. Airbag shells 58 are installed on both sides of the two internal fixing shells 51 respectively. A lens protection airbag 59 is installed inside each airbag shell 58. This design solves the problem that the labels stuck on the original device cannot be changed again when in use, and other tools are required when DIYing. It is also more troublesome to carry labels and pens for a long time when using the device.

[0019] As the first embodiment of this utility model: airbag bolt holes 41 are respectively opened on the surface of the outer protective airbag 4 on the left and right ends. Two fixing seats 513 are respectively installed on the left and right ends of the two inner fixing shells 51. The outer protective shell 3 and the inner fixing shell 51 are fixedly connected by the outer shell fixing bolts 42 and the fixing seats 513. The outer shell fixing bolts 42 are located inside the corresponding airbag bolt holes 41. Four vent pipes 541 are installed on the side surface of the high-pressure gas tank 54. The high-pressure gas tank 54 and the vent pipes 541 are connected by the gas valve 52. The other end of the vent pipe 541 passes through the rear end face of the corresponding airbag shell 58, and the other end of the vent pipe 541 is connected to the lens protective airbag 59.

Two airbag fixing straps 591 are installed on the front end face of each airbag shell 58. By adding airbag fixing straps 591, the lens protection airbag 59 can be fixed inside the airbag shell 58 when the lens protection is not required.

[0020] As a second embodiment of this utility model: when the UAV carrying the multispectral camera 1 falls during low-altitude shooting, the gyroscope 55, accelerometer 56, and angle sensor 57 will transmit abnormal data to the PLC controller 53. At this time, the PLC controller 53 will control the gas valve 52 to open, connecting the high-pressure gas tank 54 with the lens protection airbag 59. The gas inside the high-pressure gas tank 54 will quickly fill into the lens protection airbag 59, causing the lens protection airbag 59 to quickly expand and burst the airbag fixing strap 591, and protect the surface of the multispectral lens 2, thereby preventing the multispectral lens 2 from being damaged by impact.
