Description

Technical Field

[0001] This utility model relates to the field of computer vision and intelligent detection equipment technology, and in particular to a handheld device for real-time identification of concrete cracks. Background Technology

[0002] A real-time concrete crack identification handheld device is a portable device specifically designed for the rapid and accurate identification of concrete cracks on-site. It allows inspectors to directly inspect concrete structures on-site. Utilizing image processing algorithms, it can accurately identify cracks on the concrete surface, including information such as the location, width, and length of the cracks. Compared to manual visual judgment, it has higher accuracy and reduces human error.

[0003] Traditional crack detection equipment suffers from low heat dissipation efficiency. During long-term operation, the heat generated inside the device cannot be dissipated in time, making it difficult to effectively reduce the internal temperature. Furthermore, the traditional device adopts an integrated design that cannot be disassembled into smaller components, which greatly limits its storage and transportation, as well as its angle adjustment. Relying on fixed-installation cameras or drones makes it difficult to meet the needs of concrete crack detection in different environments. Based on this, a handheld device for real-time concrete crack recognition is proposed to improve the system. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A handheld device for real-time identification of concrete cracks includes a base, a shell is provided on one side of the top of the base, a motherboard is fixedly installed on the inner wall of the shell, a display screen is fixedly installed on one side of the shell, a battery is provided below the motherboard, and a heat dissipation mechanism is provided inside the shell.

[0008] A miniature fan is symmetrically mounted on one side of the housing, and a dust filter is fixedly mounted on the other side of the housing. A first heat pipe is symmetrically mounted on one side of the motherboard, and a plurality of first fins are fixedly sleeved on the outer surface of the first heat pipe.

[0009] As an improved technical solution, a folding mechanism is provided above the base, a fixed seat is fixedly connected to one side of the top of the base, a rotating shaft is rotatably connected to the top of the fixed seat, the two ends of the rotating shaft are fixedly connected to the same C-shaped plate through connecting blocks, and a shell is fixedly installed on the top of the C-shaped plate.

[0010] As an improved technical solution, a limiting bolt is threadedly connected to one side of the top of the fixed seat, and an L-shaped through groove is opened inside the rotating shaft, with one end of the limiting bolt fitting into the L-shaped through groove inside the rotating shaft.

[0011] As an improved technical solution, a protective groove is provided at the top of the base, a rubber pad is fixedly installed on the bottom wall of the protective groove, and the side of the outer shell with the display screen is fitted into the inner wall of the protective groove.

[0012] As an improved technical solution, the motherboard includes a first external interface, a charging interface, and a camera. The top of the first external interface penetrates through the inner wall of the housing and extends to the top of the housing. The top of the charging interface penetrates through the inner wall of the housing and extends to the top of the housing.

[0013] As an improved technical solution, a handle is threadedly connected to the center of the bottom end of the base, the bottom end of the handle is movably connected to the top of the tripod, and a fastening bolt is threadedly connected to the top of the tripod.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. During use, this utility model forms an effective heat dissipation system through the setting of the heat dissipation mechanism. The micro fan actively draws in air and accelerates airflow. The first and second fins increase the heat dissipation area, and the heat dissipation pipe makes the heat distribution more uniform. It can quickly and effectively dissipate the heat generated by the motherboard and other components, avoiding the device from being affected by overheating or having its service life shortened. This improves the stability and reliability of the device. The dustproof net can prevent external dust from entering the shell with the air, avoiding dust accumulation that affects the normal operation of the internal components of the device.

[0017] 3. In the use of this utility model, in some confined spaces where it is difficult to unfold the tripod, the handle can be directly connected to the base for testing; while in open spaces or in situations where high testing accuracy is required, the handle can be combined with the tripod to obtain more stable support and more flexible angle adjustment, meeting the needs of concrete crack detection in different environments, improving the versatility and practicality of the device. After the device is used up, the handle can also be easily detached for easy storage and transportation, saving space and reducing the risk of damage to the device. Attached Figure Description

[0030] like Figures 1 to 5 As shown in the figure, this embodiment provides a handheld device for real-time identification of concrete cracks, including a base 1. The device is characterized in that: a shell 5 is provided on one side of the top of the base 1, a main board 6 is fixedly installed on the inner wall of the shell 5, a display screen 64 is fixedly installed on one side of the shell 5, a battery 7 is provided below the main board 6, and a heat dissipation mechanism 8 is provided inside the shell 5.

[0031] A miniature fan 81 is symmetrically mounted on one side of the outer casing 5, and a dust filter 82 is fixedly mounted on the other side of the outer casing 5. A first heat pipe 83 is symmetrically mounted on one side of the mainboard 6. Several first fins 84 are fixedly sleeved on the outer surface of the first heat pipe 83. A heat pipe 85 is fixedly connected to the other side of the mainboard 6. A heat spreader 86 is fixedly connected to one end of the heat pipe 85. A second heat pipe 87 is fixedly connected to both ends of the heat spreader 86. Several second fins 88 are fixedly sleeved on the outer surface of the second heat pipe 87. Several first fins 84 are located on one side of the miniature fan 81, and several second fins 88 are located on one side of the dust filter 82.

[0032] Specifically, the motherboard 6 serves as the core processing unit, undertaking data processing and computation tasks related to crack recognition; the display screen 64 is used to display the recognition results in real time, allowing users to view them intuitively; and the battery 7 provides power support for the entire device.

[0033] When the device generates a large amount of heat during long-term operation, the micro fan 81 is activated. The micro fan 81 draws external air into the housing 5. When the micro fan 81 blows air toward the first fin 84, the heat generated by the motherboard 6 is conducted to the first fin 84 through the first heat pipe 83, and then carried away by the flowing air, achieving initial heat dissipation. The heat pipe 85 on the other side of the motherboard 6 can conduct the remaining heat of the motherboard 6 to the heat spreader 86. The heat spreader 86 can evenly distribute the heat to the second heat spreader 87. At this time, the air blown in from the micro fan 81 flows inside the housing 5, passes through the second fin 88, and carries away the heat on the second heat spreader 87. The dust filter 82 can prevent external dust from entering the housing 5 with the air, avoiding dust accumulation that affects the normal operation of the internal components of the device, while ensuring that hot air can be smoothly discharged from the housing 5, forming air circulation and enhancing the heat dissipation effect.

[0034] In a further embodiment, a folding mechanism 4 is provided above the base 1, a fixed seat 41 is fixedly connected to one side of the top of the base 1, a rotating shaft 42 is rotatably connected to the top of the fixed seat 41, the two ends of the rotating shaft 42 are fixedly connected to the same C-shaped plate 44 through connecting blocks, a housing 5 is fixedly installed on the top of the C-shaped plate 44, a limit bolt 43 is threadedly connected to one side of the top of the fixed seat 41, an L-shaped through groove is opened inside the rotating shaft 42, one end of the limit bolt 43 is fitted into the L-shaped through groove inside the rotating shaft 42, a protective groove 11 is opened at the top of the base 1, a rubber pad is fixedly installed on the bottom wall of the protective groove 11, and the side of the housing 5 with the display screen 64 is fitted into the inner wall of the protective groove 11.

[0035] Specifically, when the device needs to be folded and stored, the limiting bolt 43 is manually loosened so that one end of it disengages from the L-shaped through groove inside the rotating shaft 42, thus releasing the restriction on the rotation of the rotating shaft 42. Then, with the rotating shaft 42 as the center of rotation, the operator manually pushes the C-shaped plate 44. Since the two ends of the rotating shaft 42 are connected to the C-shaped plate 44 through connecting blocks, the C-shaped plate 44 will start to rotate around the rotating shaft 42. As the C-shaped plate 44 rotates, the outer shell 5 at its top also rotates synchronously and moves towards the protective groove 11. When the side of the outer shell 5 with the display screen 64 is completely fitted into the inner wall of the protective groove 11, the limiting bolt 43 is tightened again so that one end of it enters the L-shaped through groove inside the rotating shaft 42, restricting the rotation of the rotating shaft 42, thereby fixing the position of the C-shaped plate 44 and the outer shell 5, thus completing the folding and storage. At this time, the rubber pad on the bottom wall of the protective groove 11 can play a buffering and protective role, avoiding direct collision between the outer shell 5 and the protective groove 11 and causing damage.

[0036] In a further embodiment, the motherboard 6 includes a first external interface 61, a charging interface 62, and a camera 63. The top end of the first external interface 61 penetrates through the inner wall of the housing 5 and extends to the top end of the housing 5. The top end of the charging interface 62 penetrates through the inner wall of the housing 5 and extends to the top end of the housing 5. The camera 63 penetrates through the inner wall of the housing 5 and extends to the outside of one side of the housing 5.

[0037] Specifically, the first external interface 61 provides a convenient way for the device to interact with external devices, making it easy to export concrete crack identification data for further analysis and archiving. When charging the battery 7, the charger can be directly connected to the outside through the charging interface 62, simplifying the charging process and improving the ease of use. The camera 63 can directly aim at the concrete surface to take pictures of cracks, conveniently capturing crack images and providing raw data for the crack identification algorithm of the motherboard 6.

[0038] In a further embodiment, a handle 2 is threadedly connected to the center of the bottom end of the base 1, the bottom end of the handle 2 is movably connected to the top of the tripod 3, and a fastening bolt 31 is threadedly connected to the top of the tripod 3.

[0039] Specifically, in some confined spaces where the tripod 3 is difficult to unfold, the handle 2 can be directly connected to the base 1 for testing; while in open spaces or in situations where high testing accuracy is required, the handle 2 can be combined with the tripod 3 to obtain more stable support and more flexible angle adjustment, meeting the needs of concrete crack detection in different environments, improving the versatility and practicality of the device. After the device is used, the handle 2 can also be easily disassembled for easy storage and transportation, saving space and reducing the risk of damage to the device.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
