Description

Technical Field

[0001] The invention relates to the field of unmanned aerial survey integrated systems, in particular to unmanned aerial survey equipment with a condensation processor. Background Art

[0002] UAV aerial photography technology is an emerging surveying and mapping data collection technology, which obtains ground three-dimensional results by presetting ground control points, taking photos with high overlap by UAV, and performing post-aerotriangulation. Compared with manual surveying and mapping, UAV aerial photography technology has the advantages of short construction period and low personal safety accident rate. However, as it is an emerging technology, there are still some problems. For example, in the cold winter in the north, when the aerial photography equipment is moved from indoors to outdoors, a layer of dew will condense on the inner wall or lens of the equipment. At the same time, condensation will still occur after the equipment flies to high altitude for a long time. These not only affect the quality of aerial photography, but also may cause electrical short circuits due to condensation, damaging the aerial photography equipment.

[0003] The main reason for condensation on aerial survey equipment is that the air temperature outside the equipment is low, while the air temperature inside the equipment is high due to the heat generated by the equipment. When the air inside the equipment contacts the relatively low temperature shell or the inner wall of the lens, the relative humidity of the air reaches 100% and condensation forms in these parts.

[0004] The basic means to reduce condensation is to reduce air humidity. However, since the air humidity in the north is low in winter, simply placing desiccant inside the equipment cannot reduce the air humidity. Aerial photography equipment itself is difficult to provide excess power, which also makes it impossible to use the method of using the air compression principle to reduce air humidity. This problem is an important issue facing drone aerial photography in the north in winter. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a UAV aerial survey equipment with a condensation processor to reduce the air humidity inside the equipment, so that the relative humidity of the air in contact with the shell or the inner wall of the lens is lower than the saturation value, thereby reducing the possibility of condensation.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a UAV aerial survey equipment with a condensation processor, including a casing, a radar, a camera, and an integrated controller placed inside the casing, and a condensation processor is also arranged on the casing. The condensation processor includes a top cover, a condenser, a bottom bracket, a water absorbent pad, a water collecting pipe, a nut, an inner and outer thread bolt, and a rubber pad. The upper and lower parts of the casing are provided with a pair of opposite through holes, and the inner and outer thread bolts pass through the through holes on the upper part of the casing from the inside of the casing and are connected and fixed with the rubber pad and the nut on the outside of the casing. The bottom end of the water collecting pipe passes through the through holes on the lower part of the casing from the inside of the casing and is connected to the bottom bracket outside the through holes on the lower part of the casing. The water absorbent pad is placed inside the bottom bracket so that the top end of the water collecting pipe is located directly below the inner and outer thread bolts. And keep a certain distance from the inner and outer thread bolts; the lower part of the top cover has an external thread that matches the internal thread of the inner and outer thread bolts, the condenser includes a partition plate, a heat sink located at the upper part of the partition plate, and a bolt rod with an external thread located at the lower part of the partition plate, the inner side of the bolt rod is hollow, and the outer thread matches the inner thread of the inner and outer thread bolts, and the top end of the condensation needle located below the partition plate passes through the inner hollow of the bolt rod and is connected to the heat sink at the upper part of the partition plate; the top cover or the condenser can be connected to the inner and outer thread bolts respectively, and the condensation needle of the condenser passes through the inner and outer thread bolts from the outside of the casing, so that the lower part of the condensation needle is inserted into and suspended in the water collecting pipe below, and the upper part of the condensation needle is exposed in the casing, and is screwed into the inner and outer thread bolts through the bolt rod to fix the condenser on the casing.

[0007] The internal and external thread bolts are octagonal internal and external thread bolts, and the nuts are octagonal nuts.

[0008] The length of the condensation needle is one quarter of the height of the casing. There are four of them, which are thick at the top and thin at the bottom and arranged axially symmetrically. Each condensation needle has three vertical surfaces, the outer surface is an arc surface, and the two inner surfaces are vertical planes.

[0009] The distance between the top of the water collecting pipe and the inner and outer thread bolts is half the length of the condensation needle.

[0010] The condenser is made of a low-density alloy material with good thermal conductivity, and the casing is made of carbon fiber material.

[0011] The beneficial effects of the present invention are: when used in winter aerial photography surveying and mapping, the air humidity inside the aerial photography equipment is reduced, and condensation on the inner wall of the equipment and the sensor lenses of cameras, radars, etc. is reduced.

[0018] like Figure 1-3As shown, the unmanned aerial survey equipment with a condensation processor of the present invention includes a casing 4, a radar 10, a camera 11, and an integrated controller 12 placed inside the casing, and a condensation processor is also arranged on the casing 4, the condensation processor includes a top cover 1, a condenser 2, a bottom bracket 3, a water absorbent pad 5, a water collecting pipe 6, a nut 7, inner and outer thread bolts 8, and a rubber pad 9. A pair of opposite through holes are opened at the upper and lower parts of the casing 4, and the inner and outer thread bolts 8 pass through the through holes at the upper part of the casing 4 from the inside of the casing 4 and are connected and fixed with the rubber pad 9 and the nut 7 on the outside of the casing 4. The bottom end of the water collecting pipe 6 passes through the through holes at the lower part of the casing 4 from the inside of the casing 4 and is connected with the bottom bracket 3 outside the through holes at the lower part of the casing 4. The water absorbent pad 5 is placed inside the bottom bracket 3 so that the top end of the water collecting pipe 6 is located directly below the inner and outer thread bolts 8 and maintains a certain distance from the inner and outer thread bolts 8. ; The lower part of the top cover 1 has an external thread matching the internal thread of the internal and external thread bolts 8, the condenser 2 includes a partition plate 17, a heat sink 16 located at the upper part of the partition plate 17, and a bolt rod 15 with an external thread located at the lower part of the partition plate 17. The inner side of the bolt rod 15 is hollow, and the outer thread matches the inner thread of the internal and external thread bolts 8. The top end of the condensation needle 14 located below the partition plate 17 passes through the inner hollow of the bolt rod 15 and is connected to the heat sink 16 at the upper part of the partition plate; the top cover 1 or the condenser 2 can be connected to the internal and external thread bolts 8 respectively, and the condensation needle 14 of the condenser 2 passes through the internal and external thread bolts 8 from the outside of the casing, so that the lower part of the condensation needle 14 is inserted into and suspended in the water collecting pipe 6 below, and the upper part of the condensation needle 14 is exposed in the casing, and is screwed into the internal and external thread bolts 8 through the bolt rod 15, so that the condenser 2 is fixed to the casing 4.

[0019] Preferably, the internal and external thread bolts 8 are octagonal internal and external thread bolts, and the nuts 7 are octagonal nuts.

[0020] The length of the condensation needle 14 is one quarter of the height of the housing 4. There are four condensation needles 14, which are thick at the top and thin at the bottom, and are arranged symmetrically. Each condensation needle 14 has three vertical surfaces, the outer surface is a circular arc surface, and the two inner surfaces are vertical planes. The distance between the top of the water collecting pipe 6 and the inner and outer thread bolts 8 is one half of the length of the condensation needle 14.

[0021] The condenser 2 is made of a low-density alloy material with good thermal conductivity, and the housing 4 is made of carbon fiber material.

[0022] When stored indoors, the top cover 1 is connected with the inner and outer thread bolts 8, the inner and outer thread bolts 8 pass through the upper holes of the casing 4 from the inside of the casing 4 and are connected with the rubber pads 9 and the octagonal nuts 7, the water collecting pipe 6 passes through the lower hole of the casing 4 and is connected with the bottom bracket 3, the absorbent pad 5 is placed inside the bottom bracket 3, and the bottom bracket 3 is installed outside the lower hole of the casing 4; before moving from indoors to outdoors, the top cover 1 is removed, the condenser 2 is replaced at the same position and tightened, and the absorbent pad 5 is placed inside the bottom bracket 3.

[0023] The equipment is moved outdoors. At this time, since the outside temperature in winter is much lower than the temperature inside the equipment, and the thermal conductivity of the casing 4 is much lower than that of the condenser 2, during the process of slowly decreasing the temperature inside the equipment, the air humidity near the condenser 2 will first reach saturation and then condense. The dew condenses on the condensation needle 14 and, under the influence of gravity, drips into the bottom support 3 inside the water collecting pipe and is collected by the absorbent pad 5.

[0024] The device is installed on flying equipment such as drones and starts flight work. During this process, due to the heat generated by the control board 12, camera 11, radar 10 and other equipment, the temperature inside the device is always higher than the external temperature. However, due to the thermal conductivity problem, the temperature of the condenser 2 is always lower than the temperature of the inner wall of the device and the inner wall of the camera 11, radar 10 and other lenses. The air humidity near the condenser 2 reaches saturation first, and the indoor air condenses at the condensation needle 14 first, reducing the overall humidity of the air inside the device, so that the air humidity near the inner wall of the device and the inner wall of the camera 11, radar 10 and other lenses is always lower than the saturation value, and condensation is thus impossible. The dew on the condensation needle 14 is affected by gravity and drips into the bottom support 3 on the inner side of the water collecting pipe and is collected by the absorbent pad 5.

[0025] After the flight, the condenser 2 is removed, the top cover 1 is replaced in the same position and tightened, and the water-absorbing pad 5 inside the bottom bracket 3 is taken out.

[0026] The embodiments described above are only used to illustrate the technical ideas and features of the present invention, and their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. The patent scope of the present invention cannot be limited only by this embodiment, that is, any equivalent changes or modifications made to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
