Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering surveying and mapping, and in particular relates to a construction engineering surveying and mapping method and device. Background Art

[0002] Construction engineering surveying and mapping refers to the process of measuring, recording and analyzing construction sites, buildings and terrain. By using construction engineering surveying and mapping methods and equipment, geographic information is converted into digital or graphic information, which is widely used in project planning, construction guidance and building asset management and maintenance.

[0003] Common construction engineering surveying and mapping devices include: total stations, levels, theodolites, laser rangefinders, and rulers. Among them, the theodolite is a type of construction engineering surveying and mapping device used for measuring angles, engineering layout, and distance measurement. It usually consists of a measuring instrument and a tripod. When in use, the theodolite is placed on the tripod, and the center of the instrument is aligned with the ground survey station with a plumb bob or optical plummet. The instrument is leveled with a level, the measuring target is aimed with a telescope, and the horizontal and vertical angles are measured with a horizontal and vertical dial.

[0004] In the prior art, the observation lens of most common theodolites is exposed. The observation lens is an important component of the theodolite for engineering surveying and mapping. At the same time, since the measurement environment of the theodolite is characterized by direct sunlight and high dust content, the exposed theodolite observation lens is easily affected by environmental factors such as direct sunlight and dust adhesion during actual use, resulting in blurred observation, which will have a negative impact on observation accuracy. In addition, long-term direct sunlight and dust adhesion will shorten the service life of the theodolite observation lens.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0006] The object of the present invention is to provide a construction engineering surveying and mapping method and device, which can reduce the adverse effects of environmental factors on the accuracy of engineering surveying and mapping, and ensure the service life and surveying accuracy of the construction engineering surveying and mapping device.

[0007] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0008] A construction engineering surveying and mapping method comprises the following steps:

[0009] S1. Device installation: According to the requirements of engineering surveying and mapping, the surveying instrument body is fixedly assembled on the tripod and set up at the surveying and mapping location;

[0010] S2. Horizontal adjustment: adjust the horizontal state of the surveying instrument by adjusting the tripod;

[0011] S3. Surveying and mapping records: use the surveying instrument to survey the engineering building to be surveyed and map it, and record the data.

[0012] A construction engineering surveying and mapping device adopts the above-mentioned construction engineering surveying and mapping method, and further includes: a surveying instrument body, with a surveying objective lens and a surveying eyepiece fixedly mounted on both sides of the surveying instrument body. The retractable surveying and mapping protection mechanism is fixedly mounted on the outside of the surveying instrument body, and the retractable surveying and mapping protection mechanism is used to provide dustproof, sun-proof and safety protection for the surveying instrument body, the surveying objective lens and the surveying eyepiece. The retractable surveying and mapping protection mechanism includes a protective shell, which is fixedly mounted on the outside of the surveying instrument body, and a pair of objective lens protection covers and eyepiece protection covers are rotatably mounted in the protective shell. The pair of protective shells cooperate to form an objective lens dust cover, and the pair of eyepiece protection covers cooperate to form an eyepiece dust cover. The turbulent heat dissipation mechanism is mounted in the protective shell, and the turbulent heat dissipation mechanism is used to provide dustproof and heat dissipation protection for the surveying instrument body, the surveying objective lens and the surveying eyepiece.

[0013] In one or more embodiments of the present invention, a connecting base is fixedly mounted below the surveying instrument body. The connecting base connects the surveying instrument body to a tripod, and the surveying instrument body can be adjusted at multiple angles through the rotational coordination of the connecting base and the tripod. A tripod is rotatably mounted below the connecting base. The tripod supports and limits the connecting base, and the horizontal position of the surveying instrument body can be adjusted by adjusting the extended angle of the tripod.

[0014] In one or more embodiments of the present invention, a pair of base plates are fixedly connected to the bottom of the protective housing. The base plates are symmetrically mounted on the outside of the connecting base. The base plates secure the protective housing. Operating handles are hingedly connected to both sides of the protective housing. Manually grasping the operating handles allows the surveying instrument to be lifted or rotated horizontally.

[0015] In one or more embodiments of the present invention, an objective lens pulling rod is fixedly connected to the top of a pair of objective lens protective covers. The closing or unfolding state of the pair of objective lens protective covers is controlled by controlling the rotational movement of the pair of objective lens pulling rods, so that the buckling protection state of the pair of objective lens protective covers on the surveying and mapping objective lens can be adjusted. An eyepiece pulling rod is fixedly connected to the top of a pair of eyepiece protective covers. The closing and unfolding state of the eyepiece protective covers is controlled by controlling the rotational movement of the pair of eyepiece pulling rods. The top ends of the objective lens pulling rod and the eyepiece pulling rod are fixedly connected to driving gears, and a plurality of the driving gears are meshed in pairs. The meshing of the driving gears in pairs allows the pair of objective lens pulling rods and the eyepiece pulling rod to rotate and move in opposite directions under the meshing action of the driving gears.

[0016] In one or more embodiments of the present invention, a pair of drive shafts are rotatably assembled in the protective shell, and a plurality of the drive gears are fixedly sleeved on the outside of the drive shafts. The drive shafts serve to assemble, fix, and rotationally drive the drive gears. Both sides of the drive shaft are rotatably connected to shaft supports, and the shaft supports are fixedly connected to the inner wall of the protective shell. The shaft supports serve to assemble and limit the drive shaft. A drive motor is fixedly assembled on one side of the shaft support, and the output shaft of the drive motor is fixedly connected to the drive shaft. The drive motor serves to provide power, and the drive shaft is rotationally driven by controlling the operation of the drive motor.

[0017] In one or more embodiments of the present invention, protective air cushions are fixedly connected to the inner walls of a pair of objective lens protective covers and eyepiece protective covers. The protective air cushions facilitate airflow. Anti-collision pads are fixedly connected to the inner walls of the protective air cushions. The anti-collision pads act as a buffer and limiter between the objective lens protective cover, the eyepiece protective cover, and the outer walls of the surveying and mapping objective lens and the surveying and mapping eyepiece, thereby preventing collision damage to the surveying and mapping objective lens and the outer walls of the surveying and mapping eyepiece during the closing process of the objective lens protective cover and the eyepiece protective cover.

[0018] In one or more embodiments of the present invention, the turbulent heat dissipation mechanism includes a deflector frame fixedly mounted above the protective housing. The deflector frame serves to securely mount the fan and guide airflow. A fan is fixedly connected to the deflector frame. By controlling the operation of the fan, ambient air is conveyed along the fan into the deflector tube, thereby providing a basis for subsequent dust-proof and heat-dissipating protection of the surveying instrument body, surveying objective lens, and surveying eyepiece. A closed protective assembly is mounted above the deflector frame. The closed protective assembly provides enclosed protection for the deflector frame.

[0019] In one or more embodiments of the present invention, a pair of spoiler tubes are fixedly connected below the guide frame, and the other ends of the pair of spoiler tubes are respectively connected to a pair of objective lens pull rods. The spoiler tubes serve to connect the guide frame with the air duct, facilitating the transport of air within the guide frame along the spoiler tubes into the air duct. The pair of objective lens pull rods and the objective lens protective cover are each provided with an air duct, and the spoiler tubes are connected to the air duct. The air transported by the spoiler tubes is guided and transported through the air duct.

[0020] In one or more embodiments of the present invention, the protective air cushions within the pair of objective lens protective covers are each hollow and connected to the air passage. A plurality of evenly distributed turbulence holes are provided on the adjacent side of the pair of protective air cushions. Air ejected through the plurality of turbulence holes provides dust and heat protection for the surveying and mapping objective lens, reducing the risk of dust adhesion to the objective lens due to environmental influences, thereby reducing the adverse effects of dust on the surveying and mapping objective lens's accuracy.

[0021] In one or more embodiments of the present invention, a pair of symmetrically distributed exhaust holes are formed at one end of the air guide frame within the protective housing, and the exhaust holes are tilted outward. Exhausting air through the exhaust holes protects the surveying instrument body from heat dissipation, preventing the surveying instrument body from overheating due to direct sunlight during use. This ensures the surveying stability of the surveying instrument body. A pair of baffles are slidably mounted within the air guide frame, each of which is configured to cooperate with the exhaust holes. The blocking state of the exhaust holes is controlled by controlling the movement of the baffles. A blow-proof plate is fixedly connected to the side of the protective housing proximal to the surveying eyepiece. The blow-proof plate limits the air discharged from the air guide frame exhaust holes, preventing the air discharged from the exhaust holes from adversely affecting the use of the surveying eyepiece. A detachable connecting frame is fixedly connected to one end of the pair of baffles located outside the blow-proof plate. The baffles are controlled to be withdrawn and pulled by lifting the detachable connecting frame.

[0022] Compared with the prior art, the construction engineering surveying and mapping device disclosed in the present invention can protect the construction engineering surveying and mapping device as a whole by providing a retractable surveying and mapping protection mechanism, thereby greatly reducing the adverse effects of environmental factors on the construction engineering surveying and mapping device and improving the surveying and mapping accuracy of the construction engineering surveying and mapping device.

The construction engineering is observed and mapped through the surveying and mapping objective lens 101 and the surveying and mapping eyepiece 102.

[0044] like Figures 1 to 2As shown, a connecting base 5 is fixedly mounted below the surveying instrument body 1. The connecting base 5 connects the surveying instrument body 1 with the tripod 2. The surveying instrument body 1 can be adjusted to multiple angles by rotating the connecting base 5 and the tripod 2.

[0045] like Figures 1 to 2 As shown, a tripod 2 is rotatably mounted below the connecting base 5. The tripod 2 supports and limits the connecting base 5. At the same time, the horizontal state of the surveying instrument body 1 can be adjusted by adjusting the expansion angle of the tripod 2.

[0046] like Figures 2 to 3 As shown, the retractable surveying and mapping protection mechanism 3 is fixedly mounted on the outside of the surveying and mapping instrument body 1. It is used to protect the surveying and mapping instrument body 1, the surveying and mapping objective lens 101, and the surveying and mapping eyepiece 102 from dust, sunlight, and other hazards. The retractable surveying and mapping protection mechanism 3 includes a protective housing 301, which is fixedly mounted on the outside of the surveying and mapping instrument body 1. By fitting the protective housing 301 onto the outside of the surveying and mapping instrument body 1, the protective housing 301 protects the surveying and mapping instrument body 1, the surveying and mapping objective lens 101, and the surveying and mapping eyepiece 102 from dust, rain, and direct sunlight, significantly reducing the adverse effects of environmental factors on the surveying and mapping accuracy of the surveying and mapping instrument body 1. It also reduces the adverse effects of wind-blown dust and direct sunlight on the service life of the various components of the surveying and mapping instrument body 1.

[0047] like Figures 7 and 8 As shown, a pair of bottom plates 304 are fixedly connected to the bottom of the protective shell 301, and the pair of bottom plates 304 are symmetrically sleeved on the outside of the connecting seat 5. The bottom plates 304 play a role in assembling and fixing the protective shell 301.

[0048] like Figures 7 and 8 As shown, operating handles 305 are hinged on both sides of the protective shell 301. The surveying instrument body 1 can be lifted or rotated horizontally by manually supporting the operating handles 305.

[0049] like Figures 2 to 3 As shown, a pair of objective lens protective covers 302 and eyepiece protective covers 303 are rotatably mounted within a protective housing 301. The pair of protective housings 301 cooperate to form an objective lens dust cover, and the pair of eyepiece protective covers 303 cooperate to form an eyepiece dust cover. The objective lens dust cover and the eyepiece dust cover respectively protect the surveying and mapping objective lens 101 and the surveying and mapping eyepiece 102, not only providing collision protection for the surveying and mapping objective lens 101 and the surveying and mapping eyepiece 102, but also preventing dust from sticking to the surveying and mapping objective lens 101 and the surveying and mapping eyepiece 102 due to environmental factors during transportation or surveying.

[0050] like Figures 2 to 3As shown, a pair of objective lens protection covers 302 are fixedly connected to the upper portion thereof with objective lens pulling rods 306. By controlling the rotational movement of the pair of objective lens pulling rods 306, the closing or unfolding state of the pair of objective lens protection covers 302 can be controlled, thereby adjusting the locking and protection state of the pair of objective lens protection covers 302 on the surveying and mapping objective lens 101.

[0051] like Figures 2 to 3 As shown, an eyepiece pull rod 307 is fixedly connected to the top of a pair of eyepiece protective covers 303. The closing and unfolding states of the eyepiece protective covers 303 are controlled by controlling the rotational movement of the pair of eyepiece pull rods 307.

[0052] like Figures 9 and 10 As shown, the top ends of the objective lens pull rod 306 and the eyepiece pull rod 307 are fixedly connected to drive gears 308, and the multiple drive gears 308 are meshed in pairs. The meshing of the drive gears 308 allows the pair of objective lens pull rods 306 and eyepiece pull rods 307 to rotate in opposite directions under the meshing action of the drive gears 308.

[0053] like Figures 9 and 10 As shown, a pair of driving shafts 309 are rotatably mounted in the protective housing 301, and a plurality of driving gears 308 are fixedly sleeved on the outside of the driving shafts 309. The driving shafts 309 play the role of assembling, fixing and rotating the driving gears 308.

[0054] like Figures 9 and 10 As shown, both sides of the driving shaft 309 are rotatably connected to the shaft supports 310, and the shaft supports 310 are fixedly connected to the inner wall of the protective shell 301. The shaft supports 310 play the role of assembly limit for the driving shaft 309.

[0055] like Figures 9 and 10 As shown, a drive motor 311 is fixedly mounted on one side of the shaft support 310, and the output shaft of the drive motor 311 is fixedly connected to the drive shaft 309. The drive motor 311 provides power and rotates the drive shaft 309 by controlling the operation of the drive motor 311.

[0056] like Figures 2 to 3 As shown, a pair of protective air cushions 312 are fixedly connected to the inner walls of the objective lens protective cover 302 and the eyepiece protective cover 303. The protective air cushions 312 are provided to conduct airflow and transport.

[0057] like Figures 2 to 3As shown, an anti-collision protection pad 313 is fixedly connected to the inner wall of the protective air cushion 312. The anti-collision protection pad 313 can buffer and limit the outer walls of the objective lens protective cover 302, the eyepiece protective cover 303 and the surveying and mapping objective lens 101, the surveying and mapping eyepiece 102, thereby preventing the outer walls of the surveying and mapping objective lens 101, the surveying and mapping eyepiece 102 from causing collision damage during the closing process of the objective lens protective cover 302, the eyepiece protective cover 303.

[0058] like Figures 2 to 6 As shown, the turbulent heat dissipation mechanism 4 is assembled in the protective shell 301, and the turbulent heat dissipation mechanism 4 is used to protect the surveying instrument body 1, the surveying objective lens 101 and the surveying eyepiece 102 from dust and heat.

[0059] like Figures 2 to 6 As shown, the turbulent heat dissipation mechanism 4 includes a guide frame 401, which is fixedly assembled above the protective shell 301. The guide frame 401 plays the role of assembling and fixing the fan 402 and guiding the air flow.

[0060] like Figures 2 to 6 As shown, a fan 402 is fixedly connected to the guide frame 401. By controlling the operation of the fan 402, the outside air is transported along the fan 402 into the spoiler 403, thereby providing a basis for the subsequent dust and heat protection of the surveying instrument body 1, the surveying objective lens 101 and the surveying eyepiece 102.

[0061] Specifically, a closed protection component is installed above the guide frame 401. The closed protection component is used to seal and protect the guide frame 401.

[0062] like Figures 5 and 6 As shown, a circular receiving groove is provided above the guide frame 401, and a dust filter rack 409 is slidably mounted in the circular receiving groove. The dust filter rack 409 can filter the air transported from the outside to prevent dust-laden air from entering the guide frame 401 under the action of the fan 402.

[0063] like Figures 5 and 6 As shown, the dust filter rack 409 is located at one end of the circular receiving groove and is fixedly connected to a plurality of groups of evenly distributed support springs 410. The dust filter rack 409 is supported and reset by the contraction and reset of the plurality of groups of support springs 410.

[0064] like Figures 9 and 10 As shown, one end of the dust filter frame 409 outside the circular receiving groove is fixedly connected to a protective top block 411. The protective top block 411 can be used to seal and protect the top of the dust filter frame 409, thereby preventing rainwater from being transported into the guide frame 401 along the guide frame 401 during rainy days.

[0065] like Figures 9 and 10As shown, a pair of snap-fitting positioning blocks 412 are fixedly connected to the outer side of the protective top block 411, and a pair of snap-fitting plates 413 are hingedly assembled on the outer side of the deflector 401. The snap-fitting positioning blocks 412 and the snap-fitting plates 413 are arranged in cooperation with each other. The snap-fitting positioning blocks 412 and the snap-fitting plates 413 can be used to snap-fit ​​and limit the protective top block 411 and the deflector 401.

[0066] like Figures 5 and 6 As shown, a dust filter 414 and a dehumidification net 415 are fixedly mounted on the top of the guide frame 401. The dust filter 414 and the dehumidification net 415 can be used to remove dust and dehumidify the air transported into the guide frame 401.

[0067] like Figures 2 to 6 As shown, a pair of spoiler tubes 403 are fixedly connected to the bottom of the guide frame 401. The other ends of the spoiler tubes 403 are respectively connected to a pair of objective lens pull rods 306. The spoiler tubes 403 serve to connect the guide frame 401 with the air passage 404, facilitating the transfer of air from the guide frame 401 along the spoiler tubes 403 into the air passage 404.

[0068] like Figures 2 to 6 As shown, a pair of objective lens pulling rods 306 and the objective lens protection cover 302 are both provided with a conducting air channel 404, and the spoiler tube 403 is connected to the conducting air channel 404. The air transported by the spoiler tube 403 is guided and transported through the conducting air channel 404.

[0069] Specifically, the protective air cushions 312 in the pair of objective lens protection covers 302 are both hollow, and the protective air cushions 312 are connected to the air passage 404 .

[0070] like Figures 2 to 6 As shown, a pair of protective air cushions 312 are provided with a plurality of evenly distributed spoiler holes 405 on the adjacent sides. The air ejected through the spoiler holes 405 protects the surveying and mapping objective lens 101 from dust and heat, thereby reducing the possibility of dust adhesion to the surveying and mapping objective lens 101 due to environmental influences, thereby reducing the adverse effects of dust on the surveying and mapping accuracy of the surveying and mapping objective lens 101.

[0071] A pair of symmetrically distributed exhaust holes are formed at one end of the air guide frame 401 within the protective housing 301, and the holes are arranged outwardly. Exhausting air through the exhaust holes provides heat dissipation protection for the surveyor body 1, preventing the surveyor body 1 from overheating due to direct sunlight during use. This ensures the surveying and mapping stability of the surveyor body 1.

[0072] like Figures 2 to 6As shown, a pair of baffles 406 are slidably mounted in the guide frame 401, and the baffles 406 are both arranged in cooperation with the exhaust holes. The blocking state of the exhaust holes is controlled by controlling the movement of the baffles 406.

[0073] like Figures 9 and 10 As shown, a blow-proof plate 407 is fixedly connected to one side of the protective housing 301 close to the surveying eyepiece 102. The blow-proof plate 407 limits the air discharged from the exhaust hole of the guide frame 401, thereby preventing the air discharged from the exhaust hole from adversely affecting the use of the surveying eyepiece 102.

[0074] like Figures 9 and 10 As shown, one end of a pair of baffles 406 outside the anti-blowing plate 407 is fixedly connected to a disassembly and assembly connection frame 408. The baffles 406 are pulled and pulled by lifting the disassembly and assembly connection frame 408.

[0075] In specific use, when the surveying instrument body 1 is used for engineering surveying, the protective housing 301 provides a protective cover for the surveying instrument body 1, the surveying objective lens 101, and the surveying eyepiece 102. This reduces interference from direct sunlight and dusty air with the surveying process of the surveying instrument body 1, thereby ensuring the surveying accuracy of the surveying instrument body 1. Simultaneously, the drive motor 311 is controlled to drive the drive shaft 309 to rotate. The pair of drive shafts 309, meshing with the drive gears 308, can then deploy the pair of objective lens protective covers 302 and eyepiece protective covers 303, thereby placing the surveying objective lens 101 and the surveying eyepiece 102 in an unobstructed observation state. Subsequently, engineering surveying can be performed using the surveying objective lens 101 and the surveying eyepiece 102.

[0076] At the same time, during use, the engagement between the locking block 412 and the locking plate 413 can be released by rotating the locking plate 413, so that the protective top block 411 can rise under the action of the support spring 410. By controlling the operation of the fan 402, external air is allowed to enter the guide frame 401, and after being filtered and dehumidified by the dust filter frame 409, the dust filter 414 and the dehumidification net 415, it is transported along the spoiler pipe 403 and the air passage 404, and ejected through the multiple spoiler air holes 405. The air jets through the multiple spoiler air holes 405 can blow air onto the surface of the surveying and mapping objective lens 101, thereby preventing dust from adhering to the surveying and mapping objective lens 101 and causing blurred observation of the surveying and mapping objective lens 101, thereby improving the surveying and mapping accuracy of the surveying and mapping objective lens 101 and the surveying and mapping eyepiece 102. In addition, the baffle 406 can be removed by pulling out the disassembly connection frame 408, so that the air in the guide frame 401 can be discharged along the exhaust hole. The exhaust through the exhaust hole to the surveying instrument body 1 can assist in the heat dissipation of the surveying instrument body 1, thereby improving the use stability of the surveying instrument body 1 and reducing the adverse effects of environmental factors on the surveying accuracy of the surveying instrument body 1.
