Description

Technical Field

[0001] This utility model relates to the field of gimbal structure, and in particular to an explosion-proof double-sided three-axis gimbal. Background Technology

[0002] A pan-tilt head (PTZ) is a support platform used to mount load devices, typically imaging devices such as cameras and camcorders. When the imaging device is fixed on the PTG, its position and angle can be changed by moving the PTG, enabling active tracking and positioning of the target being filmed. The PTG's movement of the imaging device can also compensate for the effects of environmental disturbances (such as Brownian vibrations) on the device's position, ensuring stable operation.

[0003] In explosion-proof scenarios such as petrochemical and hazardous chemical storage, traditional inspection equipment often struggles to meet the demands of high-altitude or confined space operations due to the bulky and heavy nature of explosion-proof pan-tilt units. Existing pan-tilt units are mostly single-axis or dual-axis driven structures, lacking sufficient viewing angle adjustment capabilities to handle the multi-angle monitoring needs of complex environments. Furthermore, traditional equipment often employs an integrated design of the lifting mechanism and pan-tilt unit, requiring complete disassembly and replacement in case of failure, resulting in high maintenance costs and low efficiency.

[0004] The utility model with publication number CN206159771U discloses a three-axis gimbal and a three-axis gimbal shooting device. The first electromechanical coupling device of the three-axis gimbal includes a first hollow motor shaft with a first receiving cavity inside; the second electromechanical coupling device includes a second hollow motor shaft with a second receiving cavity inside; the pitch axis arm has a pitch axis arm receiving cavity; the roll axis assembly also includes a first wire disposed in the first receiving cavity and the roll axis arm receiving cavity; the pitch axis assembly also includes a second wire disposed in the second receiving cavity and the pitch axis arm receiving cavity for electrically connecting to the shooting device assembly. The second wire is electrically connected to the first wire so that the first wire is electrically connected to the shooting device assembly.

[0005] However, this gimbal structure is clearly unsuitable for applications in explosion-proof environments such as petrochemical and hazardous chemical storage facilities, lacking sufficient safety and reliability. Therefore, there is a need for an explosion-proof three-axis gimbal that is easy to disassemble and offers flexible viewing angle adjustment. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology, such as large size, insufficient angle adjustment capability, and poor scene adaptability of explosion-proof gimbals, and to provide an explosion-proof dual-sided three-axis gimbal.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An explosion-proof dual-sided three-axis gimbal includes a fixed housing, a rotating housing, and an observation housing. The rotating housing is rotatably mounted on the fixed housing. A vertical steering motor is installed in the fixed housing, and the output shaft of the vertical steering motor drives and connects to the rotating housing. A horizontal steering motor is installed in the rotating housing, and the horizontal steering motor drives and connects to the observation housing. A visible light camera and an infrared camera are installed in the observation housing. The observation housing includes a first sub-housing and a second sub-housing, which are symmetrically distributed on both sides of the rotating housing. The rotation center axes of the vertical steering motor and the horizontal steering motor are perpendicular to each other.

[0009] Preferably, the fixed compartment is provided with a mounting base at the end away from the rotating compartment, and the bottom end of the mounting base is provided with a mounting flange. The mounting base is detachably fixed to the inspection equipment through the mounting flange.

[0010] Preferably, protective sleeves are provided on both sides of the rotating cabin, and the output shaft of the horizontal steering motor passes through the protective sleeves and drives the observation cabin.

[0011] Preferably, the visible light camera and the infrared camera are located on the same side of the observation cabin.

[0012] Preferably, a fill light is provided on one side of the infrared camera.

[0013] Preferably, there are multiple supplementary lights, and each supplementary light is distributed in a circular array around the infrared camera.

[0014] Preferably, the infrared camera lens is provided with a protective net.

[0015] Preferably, a wiper is provided on one side of the visible light camera.

[0016] Preferably, the wiper includes a swing motor, a connecting rod, and a wiping head. One end of the connecting rod is connected to the swing motor, and the other end is connected to the wiping head. The wiping head abuts against the lens of a visible light camera.

[0017] Preferably, the rotation angle range of the rotating cabin is 360 degrees, and the rotation angle range of the observation cabin is 180 degrees.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) This solution adjusts the orientation of the camera in the horizontal plane by rotating the self-rotating cabin. Combined with the rotatable observation cabins on both sides of the rotating cabin, the orientation of the camera within the observation cabin in the vertical plane can be adjusted. This allows for adjustment of the camera's orientation to any point in space, meeting the detection requirements. Furthermore, the method of adjusting the camera's orientation by rotating the cabin results in a compact and simple structure with flexible and convenient adjustment, adapting to multi-angle detection needs in complex environments and improving the applicability and practicality of the gimbal.

[0020] (2) In this solution, a mounting base is set at the bottom of the fixed cabin. The mounting base is detachably fixed to the inspection equipment through the mounting flange. It is easy to install and remove, reduces the difficulty and cost of gimbal failure repair in the later stage, and effectively improves the efficiency of later maintenance.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0028] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides an explosion-proof dual-sided three-axis gimbal, including a fixed cabin 1, a rotating cabin 2, and an observation cabin 3. The rotating cabin 2 is rotatably mounted on the fixed cabin 1. The fixed cabin 1 is equipped with a vertical steering motor, the output shaft of which drives and connects to the rotating cabin 2. The rotating cabin 2 is equipped with a horizontal steering motor, which drives and connects to the observation cabin 3. The observation cabin 3 is equipped with a visible light camera 4 and an infrared camera 6. The observation cabin 3 includes a first sub-cabin 31 and a second sub-cabin 32, which are symmetrically distributed on both sides of the rotating cabin 2. The rotation center axes of the vertical steering motor and the horizontal steering motor are perpendicular to each other.

[0031] Working principle: The fixed cabin 1 is installed on the site inspection equipment to fix the pan-tilt unit. The rotating cabin 2 can rotate around the vertical axis of the vertical steering motor inside the fixed cabin 1. At the same time, the horizontal steering motor inside the rotating cabin 2 can drive the observation cabin 3 to rotate around the horizontal axis, thereby adjusting the orientation of the visible light camera 4 and the infrared camera 6 inside the observation cabin 3 to monitor the environment.

[0032] The rotating cabin 2 adjusts the camera's orientation in the horizontal plane by rotating itself, and in conjunction with the rotatable observation cabins 3 on both sides of the rotating cabin 2, adjusts the orientation of the camera within the observation cabin 3 in the vertical plane. This allows the camera's orientation to be adjusted to any point in space to meet detection requirements. Furthermore, the method of adjusting the camera's orientation by rotating the cabins is compact, simple, flexible, and convenient, adapting to multi-angle detection needs in complex environments and improving the gimbal's applicability and practicality.

[0033] In a preferred embodiment, a mounting base 8 is provided at the end of the fixed compartment 1 away from the rotating compartment 2, and a mounting flange is provided at the bottom end of the mounting base 8. The mounting base 8 is detachably fixed to the inspection equipment through the mounting flange.

[0034] The bottom of the fixed cabin 1 is equipped with a mounting base 8, which is detachably fixed to the inspection equipment via a mounting flange. This facilitates easy installation and removal, reduces the difficulty and cost of later gimbal malfunction repair, and effectively improves the efficiency of later maintenance.

[0035] In this embodiment, protective sleeves are provided on both sides of the rotating cabin 2. The output shaft of the horizontal steering motor passes through the protective sleeves and drives the observation cabin 3. By providing protective sleeves on the outside of the output shaft of the horizontal steering motor, the rotating cabin 2 and the observation cabin 3 are formed into a sealed structure that allows relative rotation, which improves the overall integrity of the cabin structure and thus ensures the explosion-proof rating of the cabin, ensuring its applicability in relatively harsh environments.

[0036] In this embodiment, the visible light camera 4 and the infrared camera 6 are located on the same side of the observation cabin 3. The observation cabin 3 adopts a cubic structure. By placing the two cameras on the same side of the observation cabin 3, it is convenient to adjust the orientation of the two cameras through the horizontal steering motor, simplifying the operation and improving the adjustment accuracy.

[0037] In this embodiment, a supplementary light 7 is provided on one side of the infrared camera 6. Furthermore, there are multiple supplementary lights 7, arranged in a circular array around the infrared camera 6. A protective mesh is provided on the outer side of the lens of the infrared camera 6.

[0038] Six supplementary lights 7 are evenly arranged around the infrared camera 6 to compensate for the lighting of the infrared camera 6 in low-light working environments, ensuring the accuracy of the infrared camera 6's detection. This improves the adaptability and applicability of the gimbal detection system.

[0039] In this embodiment, a wiper 5 is provided on one side of the visible light camera 4. The wiper 5 includes a swing motor, a connecting rod, and a wiping head. One end of the connecting rod is connected to the swing motor, and the other end is connected to the wiping head. The wiping head abuts against the lens of the visible light camera 4.

[0040] When the inspection equipment enters harsh operating environments, such as those with high humidity and dust levels, the lens of the visible light camera 4 is inevitably contaminated, affecting its detection accuracy. By using a swing motor to drive the wiper end to swing, the lens of the visible light camera 4 is cleaned, further improving the adaptability of the camera structure.

[0041] In this embodiment, the rotation angle range of the rotating cabin 2 is 360 degrees, and the rotation angle range of the observation cabin 3 is 180 degrees. The fixed cabin 1 is fixed, and the rotating cabin can rotate 360 ​​degrees around the fixed cabin. The two first sub-cabins 31 and the second sub-cabin 32 on the left and right can each rotate 180 degrees around the output shaft of the horizontal steering motor inside the rotating cabin, thereby satisfying the observation of 3D space by the visible light camera and the infrared camera.

[0042] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
