Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping devices, and in particular to a geographical surveying and mapping device that is convenient to move. Background Art

[0002] Geographic information refers to information related to spatial geographical distribution, which represents the general term of digital, text, graphics, images, etc. of the inherent data, quality, distribution characteristics, connections, and laws of surface objects and the environment. In urban and rural construction, land resource utilization, environmental protection and other work, it is necessary to conduct land surveys and map various maps for planning and management. In geological exploration, mineral development, water conservancy, transportation and other construction, it is necessary to conduct control surveys, mine surveys, route surveys and draw topographic maps for geological surveys and the design and construction of various buildings. And measuring these environmental data is inevitably inseparable from surveying and mapping.

[0003] Although traditional geographic information surveying and mapping instruments can achieve the function of data surveying and mapping, it is necessary to manually measure and record beside the surveying and mapping instrument in real time. The surveying position of the surveying personnel is restricted to a certain extent, which is not convenient for personnel to move and survey. Moreover, the support legs of traditional surveying and mapping instruments are mostly fixed, so it is relatively inconvenient to carry the surveying and mapping instruments.

[0004] Because during the use process, the surveying and mapping device and the tripod are two objects. After disassembling, the surveying and mapping device needs to be placed in a special toolbox, and then the staff can move the position by holding the tripod and the toolbox. Due to the weight of the tripod and the toolbox, as well as the fact that the operator is holding the tools with both hands at this time, it is extremely inconvenient to move in the wild or mountainous areas.

[0005] This not only reduces the efficiency of the surveying and mapping work, but also increases the labor intensity of the operators. Especially in complex and changeable geographical environments, such as muddy, rugged mountainous areas or swamp areas, it is extremely difficult to move the surveying and mapping device and the tripod. Any carelessness may cause damage to the surveying and mapping equipment, thus affecting the accuracy of the surveying and mapping results. Therefore, how to design a geographical surveying and mapping device that is convenient to move, easy to operate and has good stability has become a problem that needs to be solved currently.

[0006] For this reason, we have proposed a geographical surveying and mapping device that is convenient to move. Summary of the Invention

[0007] The purpose of the present invention is to provide a geographical surveying and mapping device that is convenient to move to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A geographical surveying and mapping device that is convenient to move, including a main cylinder, and a surveying and mapping instrument is slidably installed inside the main cylinder; The lower end surface of the main cylinder is provided with first sliding grooves in an internal annular array. The number of the first sliding grooves is three, and triangular support plates are slidably installed inside the three first sliding grooves. Sliders are slidably installed inside the main cylinder. The number of the sliders is three. Conveyor chains are fixedly installed at the upper ends of the three sliders. The upper lower ends of the conveyor chains are slidably installed inside the first sliding grooves. When the conveyor chains slide, they can push the triangular support plates to move.

[0009] Preferably, positive and negative motors are fixedly installed on the internal bottom surface of the main cylinder in an annular array. The number of the positive and negative motors is three. Reciprocating screws are fixedly installed on the output shafts of the positive and negative motors, and the output shafts of the positive and negative motors can drive the reciprocating screws to rotate forward and backward.

[0010] By adopting the above technical solution, when the positive and negative motors are started, the reciprocating screws can be rotated, and during the rotation, the sliders can move up and down, so as to complete the sliding in and out of the surveying instrument and the sliding in and out of the triangular support plates.

[0011] Preferably, the sliders are threadedly rotated and installed on the circumferential surfaces of the reciprocating screws, and the sliders can slide up and down on the circumferential surfaces of the reciprocating screws.

[0012] Preferably, U-shaped sliding grooves are provided on both side surfaces inside the first sliding grooves. Arc-shaped through openings are provided in an annular array on the circumferential surface of the upper end of the inner end of the main cylinder. The arc-shaped through openings are all communicated with the adjacent first sliding grooves. The conveyor chains pass through the arc-shaped through openings.

[0013] By adopting the above technical solution, the sliding of the U-shaped connecting plate can be restricted under the action of the U-shaped sliding groove, avoiding the U-shaped connecting plate from sliding out of the inside of the main cylinder, so that the triangular support plate cannot operate.

[0014] Preferably, fixing plates are fixedly installed at the upper ends of the triangular support plates. The fixing plates are slidably installed inside the first sliding grooves, and the fixing plates can drive the triangular support plates to move synchronously.

[0015] Preferably, U-shaped connecting plates are fixedly installed at the upper ends of the fixing plates. The upper ends of the fixing plates are rotatably installed inside the lower end of the U-shaped connecting plates, and damping is used at the connection between the fixing plates and the U-shaped connecting plates. The two sides of the U-shaped connecting plates are slidably installed inside the U-shaped sliding grooves.

[0016] By adopting the above technical solution, the triangular support plates can be rotated under the action of the damping, and they will not rotate by themselves after rotation, thus ensuring the stable effect of the triangular support plates.

[0017] Preferably, an installation disk is fixedly installed inside the slider in common. The structure of the installation disk is a circular structure, and a threaded hole is arranged from the upper end surface to the lower end surface of the center of the middle part. A threaded rod is rotationally installed inside the threaded hole in a threaded manner.

[0018] By adopting the above technical solution, under the action of the threaded hole and the threaded rod, the surveying instrument and the installation disk can be fixedly connected, so that during the use process, the surveying instrument can enter the inside of the main cylinder.

[0019] Preferably, a support disk is rotationally installed at the upper end of the threaded rod in a threaded manner. A threaded hole is also opened from the upper end surface to the lower end surface of the center of the support disk for rotationally connecting with the threaded rod in a threaded manner. The upper end of the support disk is rotationally connected with the surveying instrument.

[0020] Preferably, an air pump is fixedly installed at the lower end inside the main cylinder. The air pump can generate a large amount of air flow. An air delivery pipe is fixedly installed on the upper end surface of the air pump in a uniformly annular array. The number of the air delivery pipes is four. An air outlet nozzle is fixedly installed on the inner side surface of the air delivery pipe in a uniformly vertical array.

[0021] By adopting the above technical solution, a large amount of air flow can be generated under the action of the air pump. The air flow will pass through the air delivery pipe and finally be ejected through the air outlet nozzle. After being ejected, the dust on the surface of the surveying instrument can be cleaned. Therefore, the cleanliness of the surface of the surveying instrument can be ensured, and the tediousness of manual cleaning can be reduced.

[0022] Preferably, a single-hand strap is fixedly installed at the rear end of the outer side surface of the main cylinder. Symmetrically arranged shoulder straps are fixedly installed between the upper part and the lower part of the front end of the main cylinder. A threaded connection head is fixedly installed at the opening edge of the upper end of the main cylinder. A sealing cover is rotationally installed on the outer side of the threaded connection head in a threaded manner. A through hole is opened from the upper end surface to the lower end surface of the center of the sealing cover. A brushless motor is fixedly installed inside the through hole. A fan blade is fixedly installed on the output shaft of the brushless motor in a uniformly annular array. Symmetrically arranged sealing plates are rotationally installed at the edge of the through opening on the upper end surface of the sealing cover. The position where the sealing plate is rotationally connected with the sealing cover uses damping.

[0023] By adopting the above technical solution, under the action of the single-hand strap and the shoulder straps, the operator can operate according to the on-site situation. And under the action of the brushless motor and the fan blade, when the surveying instrument is being cleaned, the floating dust can be discharged from the inside of the main cylinder, thereby ensuring the cleanliness of the inside of the main cylinder and the cleanliness of the surveying instrument.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. In the process of using the present invention, driven by the forward and reverse motor, the slider can slide along the path of the reciprocating screw. During the sliding process, on the one hand, the surveying instrument can slide out of the interior of the main cylinder 1, enabling the operator to perform operations, and after the operation is completed, the surveying instrument can slide into the interior of the main cylinder, reducing the tediousness of having to disassemble the surveying instrument. On the other hand, during the use process, when the slider slides, the conveyor chain can slide inside the first chute. During the sliding process, the U-shaped connecting plate can push the fixed plate to move, and the fixed plate can push the triangular support plate to slide, so that the triangular support plate can slide out of the interior of the first chute to perform a supporting operation. And after the operation is completed, driven by the conveyor chain, the triangular support plate can directly slide into the interior of the first chute, thus reducing the trouble of disassembly.

[0025] 2. In the process of using the present invention, when the surveying instrument slides into the interior of the main cylinder, the air pump is started. The air pump will generate a large amount of air flow, and the air flow will flow along the air delivery pipe and then be ejected through the air outlet nozzle. During the ejection process, the dust on the surface of the surveying instrument can be cleaned. During the cleaning process, the brushless motor is started. Under the action of the brushless motor, the fan blades can rotate, and the air flow generated during rotation can discharge the floating dust out of the interior of the main cylinder, so as to keep the interior of the main cylinder clean and complete the cleaning operation of the surveying instrument.

[0026] 3. When the surveying instrument and the tripod support plate enter the interior of the main cylinder, at this time, the operator can, according to the actual situation on site, use a single-handed belt or a backpack to single-lift or carry the main cylinder, so as to free one hand or both hands. Thus, when the operator is working in the wild, he can free his hands to stabilize his body shape, thereby ensuring his own safety and moving the position of the surveying instrument.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 10 , the present invention provides a technical solution: A geodetic surveying and mapping device that is convenient to move, including a main cylinder 1. Among them, the structure of the main cylinder 1 is generally a circular structure, and three cut surfaces are annularly arrayed on the outer circumferential surface thereof to prevent the main cylinder 1 from rotating during the process of being carried on the back, resulting in a situation of friction. Moreover, a sweat-absorbing material and a flexible material are pasted on the outer side surface of the main cylinder 1 to further protect the operating personnel, as Figure 1 shown.

[0032] Secondly, a single-handed strap 101 made of flexible material is fixedly installed at the rear end of the outer circumferential surface of the main cylinder 1, and two symmetrically arranged shoulder straps 102 are fixedly installed on the front circumferential surface. During use, the operator can choose the single-handed strap 101 or use the shoulder straps 102 according to the situation. Therefore, the surveying and mapping operation may be in the wild. At this time, when the operator moves the device, there may be climbing situations. Therefore, the device needs to be carried by hand or on the back according to the situation.

[0033] Then, three first sliding grooves 103 are evenly opened in an annular array from the lower end surface to the inside of the main cylinder 1. Symmetric U-shaped sliding grooves 104 are opened on both inner side surfaces of the first sliding grooves 103, as Figure 2 shown. Then, three equally spaced arc-shaped through openings 105 are evenly opened in an annular array on the inner upper circumferential surface of the main cylinder 1. Moreover, the arc-shaped through openings 105 are in a through state with the inner top of the first sliding grooves 103, so that in subsequent operations, the conveying chain 4 can pass through the arc-shaped through openings 105 and then enter the inside of the first sliding grooves 103, as Figure 2 shown.

[0034] Secondly, a ring-shaped threaded connector 106 is fixedly installed at the edge of the top opening of the main cylinder 1. A sealing cover 107 is rotatably installed on the outer circumferential surface of the threaded connector 106 by threads. Among them, a circular through hole is opened from the top to the inner center position of the sealing cover 107. A brushless motor 108 is fixedly installed inside the through opening. A plurality of fan blades 109 are fixedly installed on the output shaft of the brushless motor 108. In addition, two symmetrically arranged sealing plates 110 are rotatably installed at the edge of the circular through opening on the top of the sealing cover 107, as Figure 2 and Figure 3 shown.

[0035] During use, the sealing cover 107 can be rotated and removed from the circumferential surface of the threaded connector 106, so that the surveying instrument 206 inside the main cylinder 1 can slide out of the inside of the main cylinder 1. Then, the sealing cover 107 and the threaded connector 106 are rotatably connected by threads to seal the top opening of the main cylinder 1 and prevent dust from entering. Then, after the sealing cover 107 is rotatably connected, the operator needs to rotate and open the sealing plate 110. At this time, the brushless motor 108 is started, and the output shaft of the brushless motor 108 will drive the fan blades 109 to rotate. During the rotation, a large amount of air flow will be generated, and under the action of the air flow, the dust floating inside the main cylinder 1 can be discharged from the inside of the main cylinder 1, as Figure 2 shown.

[0036] Then, three reversible motors 2 are fixedly installed on the inner bottom surface of the main cylinder 1 in a circumferential array. A reciprocating screw 201 is fixedly installed on the output shaft of each reversible motor 2. A slider 202 is threadedly and rotatably installed on the circumferential surface of each reciprocating screw 201. A circular mounting plate 203 is fixedly installed on the inner sides of the three sliders 202, as shown in Figure 6 shown.

[0037] Then, a threaded hole is formed from the upper end surface to the center position of the lower end surface of the mounting plate 203. A threaded rod 204 is threadedly and rotatably installed in the threaded hole. A circular support plate 205 is threadedly and rotatably installed on the circumferential surface of the upper end of the threaded rod 204. Since a threaded hole is also formed from the upper end surface to the center position of the lower end surface of the support plate 205, the threaded rod 204 can be threadedly connected, as shown in Figure 6 shown. Then, a surveying instrument 206 is installed at the height of the upper end surface of the support plate 205.

[0038] During use, when the reversible motor 2 is started, the output shaft of the reversible motor 2 will drive the reciprocating screw 201 to rotate. During the rotation of the reciprocating screw 201, the slider 202 will move up and down. During the up and down movement of the slider 202, the mounting plate 203 will be driven to move synchronously. During the up and down movement of the mounting plate 203, the support plate 205 will be driven to move synchronously. At this time, the support plate 205 will drive the surveying instrument 206 to move up and down. Therefore, the surveying instrument 206 can slide into or out of the main cylinder 1, enabling the operator to perform operations and store the surveying instrument 206.

[0039] In addition, an air pump 3 is fixedly installed on the inner bottom surface of the main cylinder 1, that is, in the interlayer of the main cylinder 1. The air pump 3 generates a large amount of air flow. Then, four air pipes 301 are fixedly installed on the top of the air pump 3 in a circumferential array. The upper end of the air pipe 301 is close to the opening at the inner top of the main cylinder 1, as shown in Figure 7 shown. Then, a plurality of air nozzles 302 are vertically fixedly installed on the inner side surface of the air pipe 301.

[0040] During use, after the surveying instrument 206 finishes its operation and enters the main cylinder 1, the air pump 3 is started. The air pump 3 generates a large amount of air flow, and the air flow enters the air pipe 301 and then is ejected through the air nozzles 302. At this time, since the ejected air flow has a high speed, the dust on the surface of the surveying instrument 206 can be blown away, enabling the cleaning of the surveying instrument 206. And cooperating with the brushless motor 108 can ensure the cleanliness inside the main cylinder 1.

[0041] On the outer upper end of the slider 202, a conveying chain 4 is fixedly installed. The upper end of the conveying chain 4 is slidably installed inside the first chute 103 in a U-shaped structure. Moreover, a U-shaped connecting plate 401 is fixedly installed at the lower end of the conveying chain 4 inside the first chute 103. The two ends of the U-shaped connecting plate 401 are slidably installed inside the U-shaped chute 104. And the U-shaped chute 104 and the U-shaped connecting plate 401 are in a matching state. Thus, during the subsequent sliding process of the U-shaped connecting plate 401, it can only slide up and down and will not shake. Also, the upper and lower ends of the U-shaped chute 104 are in a closed state, so that the U-shaped connecting plate 401 will not slide out of the U-shaped chute 104.

[0042] Then, a fixing plate 402 is rotatably installed on the inner side of the lower end of the U-shaped connecting plate 401. It should be noted that the position where the fixing plate 402 is rotatably connected to the U-shaped connecting plate 401 is a damped rotational connection. Therefore, during subsequent operations, when the fixing plate 402 slides out of the first chute 103, it will not rotate by itself.

[0043] Then, a triangular support plate 403 is fixedly installed at the lower end of the fixing plate 402. When the fixing plate 402 slides in the first chute 103, it can drive the triangular support plate 403 to slide synchronously inside the first chute 103. In this way, the triangular support plate 403 can slide into or out of the first chute 103. When it slides out, it can form the effect of a support operation, and when it slides in, it can facilitate the operator to take the overall equipment.

[0044] During use, when the forward and reverse motor 2 is started, the output shaft of the forward and reverse motor 2 will drive the reciprocating screw 201 to rotate synchronously. At this time, the slider 202 will drive the conveying chain 4 to move upward. When the conveying chain 4 moves upward, it will gradually enter the first chute 103. At this time, the conveying chain 4 will push the U-shaped connecting plate 401 to move downward, and then drive the fixing plate 402 to move downward synchronously. Finally, driven by the fixing plate 402, it can push the triangular support plate 403 to slide out of the first chute 103. On the contrary, when the forward and reverse motor 2 operates in the reverse direction and the slider 202 moves downward, the conveying chain 4 can gradually enter the main cylinder 1, and then the U-shaped connecting plate 401 can move upward, so that the fixing plate 402 drives the triangular support plate 403 to move upward synchronously. In this way, the triangular support plate 403 can slide into the first chute 103 to complete the overall storage operation, and then facilitate the operator to take the overall equipment.

[0045] Working principle: First, when work needs to be carried out, rotate and remove the sealing cover 107, and then start the forward and reverse motor 2. The output shaft of the forward and reverse motor 2 drives the reciprocating screw 201 to rotate. When the reciprocating screw 201 rotates, the slider 202 can move upward.

[0046] When the slider 202 moves upward, it will drive the mounting plate 203 to move synchronously. When the mounting plate 203 moves, it will drive the support plate 205 to move synchronously. At this time, the support plate 205 will drive the surveying instrument 206 to move upward synchronously, so that the surveying instrument 206 slides out of the interior of the main cylinder 1.

[0047] In addition, when the slider 202 moves upward, it will push the conveying chain 4 to pass through the arc-shaped through-hole 105 one by one and enter the interior of the first chute 103. After entering, it will push the U-shaped connecting plate 401 to slide along the path of the U-shaped chute 104. Then, after the U-shaped connecting plate 401 slides, it will push the fixing plate 402 to move downward synchronously. And during the movement, it will push the triangular support plate 403 out of the interior of the first chute 103, and then the operator rotates the triangular support plate 403 for supporting operations.

[0048] When collecting, the positive and negative motor 2 operates in reverse. At this time, under the action of the reciprocating screw 201, the slider 202 can drive the mounting plate 203 to slide into the interior of the main cylinder 1. The mounting plate 203 drives the support plate 205 to move synchronously. At this time, the surveying instrument 206 enters the interior of the main cylinder 1, threadedly rotates the sealing cover 107 and rotates the sealing plate 110.

[0049] Start the air pump 3. The air pump 3 delivers air flow into the interior of the air delivery pipe 301 and sprays it out through the air outlet nozzle 302 to clean the surveying instrument 206. Start the brushless motor 108. The output shaft of the brushless motor 108 drives the fan blade 109 to rotate, so as to generate an outward air flow to discharge the dust floating in the interior of the main cylinder 1 from the interior of the main cylinder 1.

[0050] Finally, the slider 202 drives the conveying chain 4 to enter the interior of the main cylinder 1 one by one. At this time, the conveying chain 4 will drive the U-shaped connecting plate 401 to slide upward, and then drive the fixing plate 402 to slide upward synchronously. Finally, the triangular support plate 403 enters the interior of the first chute 103.

[0051] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
