Description

Technical Field

[0001] The present invention relates to the technical field related to building structure monitoring technology, and specifically to an intelligent visual displacement monitor. Background Art

[0002] During the life cycle of building structures, they are affected by various external factors (such as wind force, earthquake, temperature change, etc.), resulting in small displacements of the structures. Although these changes are difficult to detect with the naked eye, they are often precursors to the decline of the structural safety performance. If not discovered and processed in time, serious safety accidents may be triggered. Therefore, it is necessary to monitor the displacement of building structures. Currently, the commonly used monitoring method is usually to install a monitor near the building structure, select monitoring points on the building structure to be monitored, place texture targets at the monitoring points, collect target images through the monitor, and then analyze the collected images to obtain the small displacement values of the monitored building structure.

[0003] Traditional monitors mostly use simple heat sinks or fans for heat dissipation. When using a heat sink for heat dissipation, the heat dissipation efficiency is low. Since the position of the heat sink is fixed, it is not convenient to adjust the angle of the heat sink according to the direction and speed of the air flow, resulting in poor air circulation and poor heat dissipation effect in different external air flow environments. When using a fan for heat dissipation, the fan will generate vibration during operation, which is likely to interfere with the detection results of the monitor and requires additional power supply for the fan. In addition, due to the need to be exposed to the external environment, the lens of the acquisition end of the existing monitor is easily stained with dust or mud spots, etc., resulting in unclear collected images, thereby reducing the monitoring accuracy and stability. Summary of the Invention

[0017] As a preferred technical solution of the present invention, the adjusting piece is in the shape of an equilateral triangle.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For this intelligent visual displacement monitor, by setting the heat dissipation plate, heat dissipation fins, heat dissipation channels, air injection holes, air inlets and adjustment components, when the external air flow speed and direction change, the wind vane will drive the drive rod to rotate. The rotation of the drive rod drives the threaded rod to rotate through the worm and worm gear. The rotation of the threaded rod drives the drive plate and the first toothed plate to move. The movement of the first toothed plate drives the heat-conducting copper column and the heat dissipation fins to rotate through the transmission gear, so as to adjust the angle of the heat dissipation fins, which can adaptively adjust the angle of the heat dissipation fins to always maintain the best included angle with the air flow direction, and can make the best use of the air flow for heat dissipation to the greatest extent.

[0020] 2. For this intelligent visual displacement monitor, by adopting a non-uniform arrangement of the air injection holes, in the central area of the high lens, since the monitoring accuracy requirement is relatively high, the air injection holes are arranged relatively densely. In the edge area of the high lens, the distance between the air injection holes is appropriately increased. Such an arrangement method can not only ensure the formation of a high-strength air curtain protection in the key area, but also reasonably allocate the air flow resources to avoid unnecessary energy consumption. At the same time, the air injection holes on the upper and lower sides are both inclined, forming a uniform and stable conical air curtain in front of the high lens, covering the high lens in all directions, effectively blocking dust from approaching, and further improving the dust-proof effect of the device.

[0021] 3. For this intelligent visual displacement monitor, by setting the air curtain dust-proof component, the electric push rod pushes the second toothed plate to move. The movement of the second toothed plate drives the ring sleeve and the internal toothed ring to rotate through the external toothed ring. The rotation of the internal toothed ring drives several column gears and the rotating shaft to rotate. The rotation of the column gears drives the rack and the adjusting piece to move, so that the adjusting piece slides closely against the adjacent adjusting piece. Several adjusting pieces move synchronously and can adaptively adjust the jet area of the air injection holes, and then adaptively adjust the diffusion range of the gas ejected from the air injection holes. Specifically, in a dusty environment, by contracting the electric push rod, several adjusting pieces are driven to move away from each other, increasing the jet area of the air injection holes, thereby expanding the air flow diffusion angle and making the air curtain cover a wider area; in a normal environment, by extending the electric push rod, several adjusting pieces are driven to move closer to each other, reducing the jet area of the air injection holes, narrowing the diffusion angle, and enhancing the air curtain intensity.

[0022] 4. For this intelligent visual displacement monitor, by setting up a lens cleaning unit, when the air convection outside the monitor is relatively strong, dust prevention by the air flow ejected from the air jet outlet cannot meet the high lens dust prevention requirements. At this time, the high-speed air flow will drive the driving fan blade to rotate. The rotation of the driving fan blade drives the rotation of the rotating shaft and the transmission rod. The rotation of the transmission rod drives the winding wheel to wind the cable. During the winding process of the cable, the first spring is wound, and the cleaning plate is driven to move. During the movement of the cleaning plate, the surface of the high lens is cleaned by the cleaning brush, removing the dust and impurities attached to the surface of the high lens, thus ensuring the cleanliness of the high lens surface, avoiding the interference caused by the remaining dust on the high lens surface to the operation of the monitor, enriching the dust prevention means of the device, and further improving the dust prevention effect of the device.

[0023] 5. For this intelligent visual displacement monitor, by setting up a filter screen cleaning unit, when the rotating shaft rotates, it drives the eccentric disc to rotate at the same time. The rotation of the eccentric disc drives the sliding sleeve to reciprocate. Under the action of its own elastic force, the second spring enables the sliding sleeve to continuously fit with the eccentric disc, so that the eccentric disc drives the striking rod to reciprocate and strike the dust prevention filter screen during the rotation process, shaking off the dust on the dust prevention filter screen, preventing the dust prevention filter screen from being blocked, and cleaning the filter screen. The operation is simple and convenient to use.

[0024] 6. For this intelligent visual displacement monitor, by setting up a wind vane and a driving fan blade, using the characteristic that the wind vane follows the air flow direction to adjust the angle of the heat dissipation fins through the rotation of the wind vane, thereby enhancing the heat dissipation effect of the device. By setting up the driving fan blade, using the wind power to drive the driving fan blade to rotate to realize the cleaning and dust prevention operations of the high lens and the dust prevention filter screen, effectively utilizing the natural wind power resources to realize the dust prevention and heat dissipation operations, without an additional power source, energy-saving and environmentally friendly.

Specific embodiments

[0041] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0042] Embodiment: As Figures 1 to 13As shown in the figure, an intelligent vision displacement monitor of the present invention includes a mounting base 1 and a bracket 2 arranged on the mounting base 1. A monitor main body 3 is arranged on the bracket 2. The monitor main body 3 includes an outer housing 4 fixedly installed on the bracket 2 and an inner housing 5 arranged inside the outer housing 4. There are gaps between the upper surface and the lower surface of the inner housing 5 and the inner walls of the outer housing 4 on the same side, forming a heat dissipation channel 6. An image acquisition device 7 and a heat dissipation plate 8 fixedly connected to the image acquisition device 7 are arranged inside the inner housing 5. A camera port is opened on one side of the outer housing 4, and a plurality of air inlets 9 are opened on the other side of the outer housing 4. A high lens 10 is fixedly installed on the inner housing 5 opposite to the acquisition end of the image acquisition device 7. A plurality of heat conducting copper columns 11 are rotatably installed on both the upper and lower sides of the heat dissipation plate 8. One end of each heat conducting copper column 11 away from the heat dissipation plate 8 extends into the heat dissipation channel 6 on the same side and is fixedly installed with a heat dissipation fin 12. A heat dissipation adjustment component 13 for adjusting the angle of the heat dissipation fins 12 is arranged inside the inner housing 5. A dust-proof filter screen 14 is arranged inside the outer housing 4 near the air inlet 9. A cleaning and dust-proof component 15 for cleaning the high lens 10 and the dust-proof filter screen 14 is arranged inside the outer housing 4; Two air guide plates 16 are fixedly installed on one side of the inner housing 5 close to the high lens 10. The two air guide plates 16 are symmetrically arranged and are respectively located on both sides of the high lens 10. A plurality of air jet holes 17 are opened on each air guide plate 16. An air curtain dust-proof component 18 is arranged on the air guide plate 16;

[0043] The heat dissipation adjustment component 13 includes a driving rod 131 rotatably installed inside the inner housing 5. The top end of the driving rod 131 extends outside the outer housing 4 and is fixedly installed with a wind vane 132. A driving plate 133 is slidably attached to the heat dissipation plate 8. A threaded rod 134 is threadedly installed on the driving plate 133. A worm 137 is fixedly installed on the driving rod 131. A worm gear 138 meshing with the worm 137 is fixedly installed on the threaded rod 134. First toothed plates 135 are fixedly installed on both the upper and lower sides of the driving plate 133. A transmission gear 136 is fixedly installed on each heat conducting copper column 11. The transmission gear 136 meshes with the first toothed plate 135 on the same side.

[0044] Specifically, the high lens 10 can protect the image acquisition device 7. Without affecting the shooting and acquisition of the image acquisition device 7, it can isolate the image acquisition device 7 from the external environment, avoiding damage to the image acquisition device 7. The heat generated by the image acquisition device 7 during operation is transported to the heat dissipation fins 12 via the heat dissipation plate 8 and the heat conducting copper columns 11. By setting a plurality of heat dissipation fins 12, the heat dissipation area of the heat dissipation plate 8 can be increased, improving the heat dissipation efficiency of the monitor main body 3. Air enters the heat dissipation channel 6 from one side of the air inlet 9 and is ejected from the air ejection holes 17 after passing through the heat dissipation channel 6 and the heat dissipation fins 12, thereby taking out the heat on the heat dissipation fins 12 and realizing the heat dissipation operation of the monitor main body 3. At the same time, by setting the heat dissipation adjustment component 13, when the air flow speed and direction in the external environment change, the wind vane 132 will drive the driving rod 131 to rotate. The rotation of the driving rod 131 drives the threaded rod 134 to rotate through the worm gear 138 and the worm 137. The rotation of the threaded rod 134 drives the driving plate 133 and the first toothed plate 135 to move. The movement of the first toothed plate 135 drives the heat conducting copper columns 11 and the heat dissipation fins 12 to rotate through the transmission gear 136, thereby adjusting the angle of the heat dissipation fins 12, which can adaptively adjust the angle of the heat dissipation fins 12 to always maintain the best angle with the air flow direction, enabling the maximum utilization of air flow for heat dissipation. Specifically, in a natural convection environment, the air flow speed is relatively slow. The heat dissipation fins 12 should increase the contact area with the air as much as possible to promote heat exchange. At this time, the wind vane 132 does not rotate or rotates at a small angle, and the angle of the heat dissipation fins 12 is close to the vertical direction, which can make the air better contact with the fins during the natural rising or falling process, enhancing the air flow deflection effect, improving the heat exchange efficiency, and enhancing the heat dissipation effect. In a forced convection environment, such as in a well-ventilated environment, the air flow speed is fast. At this time, the wind vane 132 will deflect and finally be consistent with the air flow direction, making the angle between the heat dissipation fins 12 and the air flow smaller to avoid excessive air flow resistance and energy loss, while ensuring sufficient heat exchange area and enhancing the heat dissipation effect. In addition, by ejecting the heat generated by the image acquisition device 7 during operation from the air ejection holes 17, the surface of the high lens 10 can be defogged and defrosted, avoiding the fog and frost attached to the surface of the high lens 10 from affecting the accuracy of the sampling results.

[0045] Furthermore, two triangular flow guiding plates 19 are fixedly installed in each heat dissipation channel 6. The two flow guiding plates 19 are symmetrically arranged, and the cross-section of the heat dissipation channel 6 gradually narrows from the side of the air inlet 9 to the side of the air ejection holes 17, which can make the air gradually accelerate during the process of flowing from the side of the air inlet 9 to the side of the air ejection holes 17, improving the heat dissipation efficiency.

[0046] Furthermore, several air nozzles 17 are arranged non-uniformly. The air nozzles 17 located in the central area of the high lens 10 are arranged relatively densely, while the air nozzles 17 located in the edge area of the high lens 10 are arranged relatively sparsely. The air nozzles 17 are arranged obliquely and the included angle with the high lens 10 is 30 degrees. By adopting the non-uniform arrangement of the air nozzles 17, in the central area of the high lens 10, due to the relatively high requirement for monitoring accuracy, the air nozzles 17 are arranged relatively densely. In the edge area of the high lens 10, the spacing between the air nozzles 17 is appropriately increased. Such an arrangement method can not only ensure the formation of a high-strength air curtain protection in the key area, but also reasonably allocate the air flow resources to avoid unnecessary energy consumption. At the same time, the air nozzles 17 on both the upper and lower sides are arranged obliquely to form a uniform and stable conical air curtain in front of the high lens 10, covering the high lens 10 in all directions, effectively blocking the dust from approaching, and further improving the dust-proof effect of the equipment.

[0047] Among them, the cleaning and dust-proof component 15 includes a lens cleaning unit 151 and a filter screen cleaning unit 152. The lens cleaning unit 151 includes a cleaning brush plate 1511 slidably mounted on one side of the high lens 10 in the inner housing 5. A cleaning brush is detachably mounted on the cleaning brush plate 1511, and the brushing surface of the cleaning brush is attached to the high lens 10. A plurality of first springs 1512 are fixedly mounted on the cleaning brush plate 1511. The end of the first spring 1512 away from the cleaning brush plate 1511 is fixedly connected to the outer housing 4. A transmission rod 1513 is rotatably mounted in the outer housing 4. One end of the transmission rod 1513 is fixedly mounted with a winding wheel 1514, and a cable 1515 is wound around the winding wheel 1514. One end of the cable 1515 is fixedly connected to the winding wheel 1514, and the other end is fixedly connected to the cleaning brush plate 1511. The other end of the transmission rod 1513 is fixedly mounted with a second bevel gear 1516. A rotating shaft 1517 is rotatably mounted on the inner housing 5, and a first bevel gear 1519 meshing with the second bevel gear 1516 is fixedly mounted on the rotating shaft 1517. The top end of the rotating shaft 1517 extends outside the outer housing 4 and is fixedly mounted with a driving fan blade 1518. When the air convection outside the monitor is relatively strong, dust prevention by the airflow ejected from the air jet port cannot meet the dust prevention requirements of the high lens 10, and the dust carried by the airflow is likely to adhere to the surface of the high lens 10 and the dust-proof filter screen 14. At this time, the high-speed airflow will drive the driving fan blade 1518 to rotate. The rotation of the driving fan blade 1518 drives the rotating shaft 1517 to rotate. The rotation of the rotating shaft 1517 drives the transmission rod 1513 to rotate through the first bevel gear 1519 and the second bevel gear 1516. The rotation of the transmission rod 1513 drives the winding wheel 1514 to wind the cable 1515. During the winding process of the cable 1515, the first spring 1512 is pulled, and the cleaning brush plate 1511 is driven to move. During the movement of the cleaning brush plate 1511, the surface of the high lens 10 is cleaned by the cleaning brush, and the dust and impurities attached to the surface of the high lens 10 are removed, so as to ensure the cleanliness of the surface of the high lens 10, avoid the remaining dust on the surface of the high lens 10 from affecting the operation of the monitor and causing interference, enrich the dust prevention means of the device, and further improve the dust prevention effect of the device. At the same time, by using the natural wind resources to realize the dust prevention and cleaning operation, no additional power source is required.

[0048] Among them, a telescopic rod is fixedly mounted in each first spring 1512, and the two ends of the telescopic rod are respectively fixedly connected to the cleaning brush plate 1511 and the outer housing 4. The telescopic rod can guide and limit the first spring 1512 during the telescopic process, ensuring the stability of the first spring 1512 during telescoping.

[0049] Among them, the filter screen cleaning unit 152 includes an eccentric disc 1521 fixedly installed on the rotating shaft 1517. An installation frame 1522 is fixedly installed inside the outer housing 4. The dust-proof filter screen 14 is detachably installed in the installation frame 1522 through a buckle. A connecting plate 1523 is fixedly installed on the installation frame 1522. A striking rod 1524 is slidably installed on the connecting plate 1523. A sliding sleeve 1525 is fixedly installed at one end of the striking rod 1524 close to the eccentric disc 1521, and the sliding sleeve 1525 fits and slides on the surface of the eccentric disc 1521. A second spring 1526 is sleeved on the striking rod 1524, and both ends of the second spring 1526 are fixedly connected to the connecting plate 1523 and the sliding sleeve 1525 respectively. When the rotating shaft 1517 rotates, it drives the eccentric disc 1521 to rotate. The rotation of the eccentric disc 1521 drives the sliding sleeve 1525 to reciprocate. Under the action of its own elastic force, the second spring 1526 enables the sliding sleeve 1525 to continuously fit with the eccentric disc 1521, so that the eccentric disc 1521 drives the striking rod 1524 to reciprocate and strike the dust-proof filter screen 14 during rotation, shaking off the dust on the dust-proof filter screen 14, preventing the dust-proof filter screen 14 from being blocked, cleaning the filter screen, with simple operation and convenient use, and without an additional power source.

[0050] Among them, a dust collection box 1527 is inserted on one side of the outer housing 4 close to the dust-proof filter screen 14, and one side of the dust collection box 1527 is in contact with the dust-proof filter screen 14. By setting the dust collection box 1527, it is convenient to collect the dust that oscillates and falls on the dust-proof filter screen 14 and timely remove the collected dust.

[0051] Among them, the air curtain dust prevention component 18 includes two second toothed plates 181 that slide on two air guide plates 16 respectively. An electric push rod 182 is fixedly installed on the air guide plate 19 on one side of the second toothed plate 181. The output end of the electric push rod 182 is fixedly connected to the second toothed plate 181 on the same side. A ring sleeve 183 is rotatably installed in each air jet hole 17. An external toothed ring 184 that meshes with the second toothed plate 181 is fixedly installed on the outer surface of the ring sleeve 183. An internal toothed ring 185 is fixedly installed on the inner surface of the ring sleeve 183. A circular ring 186 is fixedly installed in the ring sleeve 183, and a number of rotating shafts 187 are rotatably installed on the circular ring 186. A driving gear 188 that meshes with the internal toothed ring 185 is fixedly installed on each rotating shaft 187. Six adjusting pieces 189 are evenly slidably installed on the circular ring 186. Two adjacent adjusting pieces 189 are slidably attached to each other. A rack 1810 that meshes with the driving gear 188 on the same side is fixedly installed on the adjusting piece 189. The shape of the adjusting piece 189 is an equilateral triangle. The electric push rod 182 pushes the second toothed plate 181 to move. The movement of the second toothed plate 181 drives the ring sleeve 183 and the internal toothed ring 185 to rotate through the external toothed ring 184. The rotation of the internal toothed ring 185 drives a number of column gears and rotating shafts 187 to rotate. The rotation of the column gears drives the rack 1810 and the adjusting piece 189 to move, so that the adjusting piece 189 slides closely against the adjacent adjusting piece 189. A number of adjusting pieces 189 move synchronously and can adaptively adjust the jet area of the air jet hole 17, and further adaptively adjust the diffusion range of the gas ejected from the air jet hole 17. Specifically, in a dusty environment, the electric push rod 182 contracts to drive a number of adjusting pieces 189 to move away from each other, increasing the jet area of the air jet hole 17, thereby expanding the air flow diffusion angle and making the air curtain cover a wider area; in a normal environment, the electric push rod 182 extends to drive a number of adjusting pieces 189 to move closer to each other, reducing the jet area of the air jet hole 17, narrowing the diffusion angle, and enhancing the air curtain intensity.

[0052] Among them, six guiding columns 1811 are fixedly installed on the circular ring 186. A guiding groove is formed on each adjusting piece 189. The guiding column 1811 fits and slides in the guiding groove on the same side. By using the cooperation of the guiding groove and the guiding column 1811, the movement of the adjusting piece 189 can be guided and limited to ensure the stability of the adjusting piece 189 during movement.

[0053] During operation, when in use, the device is installed at a suitable position through the mounting seat 1. Monitoring points are selected on the building structure to be monitored, and texture targets are placed at the monitoring points. The target images are collected through the image acquisition device 7, and then the collected images are analyzed to obtain the micro displacement values of the monitored building structure (this is the prior art and the process will not be elaborated here);

[0054] During use, the high lens 10 can protect the image acquisition device 7. Without affecting the shooting and acquisition of the image acquisition device 7, it can isolate the image acquisition device 7 from the external environment, avoiding damage to the image acquisition device 7. The heat generated by the image acquisition device 7 during operation is transported to the heat dissipation fins 12 through the heat dissipation plate 8 and the heat conduction copper column 11. Air enters the heat dissipation channel 6 from one side of the air inlet 9 and is ejected from the air jet holes 17 after passing through the heat dissipation channel 6 and the heat dissipation fins 12, thereby taking out the heat on the heat dissipation fins 12 and realizing the heat dissipation operation of the device. When the external air flow speed and direction change, the wind vane 132 drives the driving rod 131 to rotate. The rotation of the driving rod 131 drives the threaded rod 134 to rotate through the worm gear 138 and the worm 137. The rotation of the threaded rod 134 drives the driving plate 133 and the first toothed plate 135 to move. The movement of the first toothed plate 135 drives the heat conduction copper column 11 and the heat dissipation fins 12 to rotate through the transmission gear 136, thereby adjusting the angle of the heat dissipation fins 12, adaptively adjusting the angle of the heat dissipation fins 12 to always maintain the best included angle with the air flow direction, and being able to utilize air flow heat dissipation to the greatest extent;

[0055] When the air convection outside the monitor is relatively strong, the high-speed air flow drives the driving fan blade 1518 to rotate. The rotation of the driving fan blade 1518 drives the rotating shaft 1517 to rotate. The rotation of the rotating shaft 1517 drives the transmission rod 1513 to rotate through the first bevel gear 1519 and the second bevel gear 1516. The rotation of the transmission rod 1513 drives the winding wheel 1514 to wind the cable 1515. During the winding process of the cable 1515, the first spring 1512 is wound and the cleaning plate 1511 is driven to move. During the movement of the cleaning plate 1511, the surface of the high lens 10 is cleaned by the cleaning brush, removing the dust and impurities attached to the surface of the high lens 10. At the same time as the rotating shaft 1517 rotates, the eccentric disc 1521 rotates. The rotation of the eccentric disc 1521 drives the sliding sleeve 1525 to reciprocate. Under the action of its own elastic force, the second spring 1526 enables the sliding sleeve 1525 to continuously fit with the eccentric disc 1521, so that the eccentric disc 1521 drives the striking rod 1524 to reciprocate and strike the dust-proof filter screen 14 during rotation, shaking off the dust on the dust-proof filter screen 14 and preventing the dust-proof filter screen 14 from being blocked, cleaning the filter screen. The operation is simple and convenient to use, and no additional power source is required;

[0056] During the use, the jet area of the air jet hole 17 can be adaptively adjusted according to the external dust concentration at any time. That is, the electric push rod 182 drives the second tooth plate 181 to move. The movement of the second tooth plate 181 drives the ring sleeve 183 and the internal tooth ring 185 to rotate through the external tooth ring 184. The rotation of the internal tooth ring 185 drives several column gears and the rotating shaft 187 to rotate. The rotation of the column gears drives the rack 1810 and the adjusting piece 189 to move, so that the adjusting piece 189 slides closely against the adjacent adjusting piece 189, thereby adaptively adjusting the diffusion range of the gas ejected from the air jet hole 17. Specifically, in a dusty environment, the electric push rod 182 contracts to drive several adjusting pieces 189 to move away from each other, increasing the jet area of the air jet hole 17, thereby expanding the airflow diffusion angle and making the air curtain cover a wider area. In a normal environment, the electric push rod 182 extends to drive several adjusting pieces 189 to move closer to each other, reducing the jet area of the air jet hole 17, narrowing the diffusion angle, and enhancing the air curtain strength.
