Description

Technical Field

[0001] The present invention relates to the technical field of geographic surveying and mapping instruments, in particular to a portable geographic information surveying and mapping instrument that is a geographic information collection device. Background Art

[0002] Geographic information refers to information related to spatial geographic distribution. It is a general term for numbers, text, graphics, and images that represent the inherent data, quality, distribution characteristics, connections, and regularities of surface objects and the environment. In urban and rural construction, land resource utilization, and environmental protection, land surveying and mapping are necessary for planning and management. In geological exploration, mineral development, water conservancy, and transportation construction, control surveying, mine surveying, route surveying, and topographic mapping are necessary for geological surveys and the design and construction of various buildings. Measuring these environmental data is inseparable from surveying instruments.

[0003] Before use, the surveying instrument generally needs to be installed on a foldable tripod bracket for carrying and surveying. When surveying in mountainous areas, due to the uneven ground, the length of the bracket needs to be adjusted to ensure the stability of the surveying instrument. Due to the uneven ground, when the device encounters strong winds during surveying, it is easy for one side of the device to be subjected to excessive force and cause shaking or tilting, affecting the surveying accuracy and stability during surveying.

[0025] The connecting assembly comprises a circular shaft which is slidably connected between three connecting ears, and the outer surface of the circular shaft is rotatably connected with three long rods.

[0026] Furthermore, the top of the T-shaped frame is rotatably connected to the end of the long rod away from the circular axis;

[0027] The flip assembly includes a rectangular flip plate slidably connected to the inside of the T-shaped frame, and the side of the rectangular flip plate close to the telescopic bracket is rotatably connected to the side wall of the telescopic bracket;

[0028] The left and right inner walls of the rectangular flip plate are both provided with sliding grooves, and the inner wall of the rectangular flip plate on the side close to the sliding groove is provided with a stepped wave groove.

[0029] Furthermore, the auxiliary component includes a spring rod slidably connected to a side of the rectangular flip plate away from the telescopic bracket, and a tilting frame is provided on the top of the spring rod;

[0035] Wherein, a conical frame is slidably connected between the two stepped wave grooves, and the top of the conical frame contacts the bottom of the sliding belt.

[0036] The present invention has the following beneficial effects:

[0037] 1. The present invention uses elastic components and connecting components. When wind acts on the folding plate and the flexible layer, the folding plate will drive the circular axis to move downward after being subjected to downward pressure. When multiple circular axis are subjected to downward pressure during strong wind flow, they can not only provide support between the three telescopic brackets, but also reduce the overall center of gravity height of the device. At the same time, when wind blows towards the device, the counterweight plate will drive the telescopic rod to swing at the bottom of the main body under the flow of wind. The multi-angle swing of the flexible layer can absorb and dissipate the force acting on the telescopic bracket during wind flow, thereby reducing and suppressing the swing amplitude of the surveying instrument during surveying, reducing the shaking or tilting caused by excessive force on one side in strong winds, thereby improving the surveying accuracy and stability during surveying.

[0038] 2. The present invention, through the connection components and auxiliary mechanisms, when the telescopic bracket drives the rectangular flip plate to slide, a corresponding sliding frame will drive the sliding belt to rotate in a circular manner when the rectangular flip plate slides and make the sliding belt in a tightened state. At the same time, when the other two rectangular flip plates slide, the sliding belts on the rectangular flip plates will slide in the opposite direction of the sliding of the rectangular flip plates under the push of the spring rod, and can increase the contact area between the rectangular flip plates and the ground. At the same time, through the insertion of the sliding frame and the ground, the grip between the device and the ground can be improved, thereby reducing the situation where the device slides due to the influence of large lateral wind force in the process of guiding wind sliding during surveying. This dynamic adjustment mechanism further enhances the stability during surveying and mapping, maintains high surveying and mapping accuracy, and can also reduce data fluctuations during surveying and mapping.

[0039] 3. The present invention uses a flip assembly and a reinforcement assembly. When the conical frame slides downward, it pushes the spring plate to slide downward. When the spring plate slides downward, it can push multiple arc plates to extend out of the sliding frame and insert into the ground to form a barb-like structure. This reduces the problem of the sliding frame being separated from the ground due to the soft soil when the device slides, making it difficult to effectively insert the device. This can further enhance the stability of the device's grip on the ground during surveying and mapping, and improve its wind resistance efficiency.

[0040] 4. The present invention uses a reinforcement component. When the conical frame swings up and down, the swing of the conical frame can drive the sliding belt to swing synchronously. At this time, the sliding belt can be in close contact with the inclined frame during the swing. At this time, when the sliding belt swings, it can generate intermittent pulling force on the sliding frame, so that the sliding frame can hook deep into the ground soil at the bottom arc, increasing the insertion depth. At the same time, it can also make the sliding belt clean the soil attached to the sliding belt when in contact with the inclined frame during the swing, thereby reducing the situation where the sliding belt and the ground slip due to the adhesion of soil and affect the grip, thereby enhancing the insertion depth and stability of the sliding frame into the soil.

[0041] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The elastic component 21 is installed on the side wall of the short shaft 201;

[0067] The connecting component 22 is installed on the side wall of the elastic component 21 .

[0068] The auxiliary mechanism 3 includes a plurality of T-shaped brackets 301 provided on the side wall of the connecting assembly 22. The auxiliary mechanism 3 includes:

[0069] The flip assembly 31 is slidably disposed on the side wall of the T-shaped frame 301;

[0070] An auxiliary component 32, the auxiliary component 32 is slidably disposed inside the flip component 31;

[0071] The reinforcement component 33 is installed on the side wall of the flip component 31.

[0072] The buckle assembly 11 includes an adjustment frame 111 fixedly connected to the outer surface of the telescopic bracket 101;

[0073] The left side of the adjustment frame 111 is fixedly connected to a snap ring 112 , and the side of the adjustment frame 111 away from the snap ring 112 is fixedly connected to a snap column 113 ;

[0074] The telescopic assembly 12 includes a counterweight plate 122 rotatably connected to the bottom of the telescopic rod 121. First, the three telescopic brackets 101 are opened and the length of the telescopic brackets 101 is adjusted according to the required height. Then, they are placed on the required ground and the surveyor 4 is installed on the top of the main body 1. Then, the surveyor 4 is opened for surveying. After the surveying is completed, the telescopic brackets 101 are folded and the three telescopic brackets 101 are closed.

[0075] The elastic component 21 includes a folding plate 211 fixedly connected between the two short shafts 201, a flexible layer 212 fixedly connected to the top of the folding plate 211, and a connecting ear 213 fixedly connected to the side of the folding plate 211 close to the telescopic rod 121;

[0076] The connecting assembly 22 includes a circular shaft 221 that is slidably connected between the three connecting ears 213. The outer surface of the circular shaft 221 is rotatably connected to three long rods 222. When the telescopic bracket 101 drives the folding plate 211 to unfold during the unfolding process, the unfolding of the folding plate 211 will drive the circular shaft 221 to slide downward. When the circular shaft 221 slides downward, the counterweight plate 122 will slide downward. Subsequently, when strong winds occur during the detection process, the flow of strong winds will flow through the surface of the flexible layer 212 when passing through the telescopic bracket 101.

[0077] The top of the T-shaped frame 301 is rotatably connected to the end of the long rod 222 away from the circular shaft 221;

[0078] The flip assembly 31 includes a rectangular flip plate 311 slidably connected to the inside of the T-shaped frame 301. The rectangular flip plate 311 is rotatably connected to the side wall of the telescopic bracket 101 on one side close to the telescopic bracket 101.

[0079] Among them, the left and right inner walls of the rectangular flip plate 311 are both provided with sliding grooves 312, and the inner wall of the rectangular flip plate 311 close to the sliding groove 312 is provided with a stepped wave groove 313. When the rectangular frame 301 slides, it will push the rectangular flip plate 311 to flip downward on the side wall of the telescopic bracket 101. When the rectangular flip plate 311 flips downward, the sliding frame 331 will be inserted into the ground. Subsequently, when the entire device slides in strong winds during surveying, the sliding of the telescopic bracket 101 can drive the rectangular flip plate 311 to slide synchronously.

[0080] The auxiliary component 32 includes a spring rod 321 slidably connected to the side of the rectangular flip plate 311 away from the telescopic bracket 101, and a tilting frame 322 is provided on the top of the spring rod 321;

[0081] The bottom of the tilting frame 322 is fixedly connected to the side wall of the rectangular flip plate 311 .

[0082] The reinforcement assembly 33 includes a sliding frame 331 slidably connected between the two sliding slots 312 , a spring plate 332 is fixedly connected to the bottom inner wall of the sliding frame 331 , and an auxiliary spring is fixedly connected to the side of the sliding frame 331 close to the telescopic bracket 101 ;

[0083] Among them, one end of the auxiliary spring away from the sliding frame 331 is fixedly connected to the inner wall of the rectangular flip plate 311, and the corresponding sliding frame 331 will drive the sliding belt 334 to rotate in a circle when the rectangular flip plate 311 slides and make the sliding belt 334 in a tightened state. At the same time, when the other two rectangular flip plates 311 slide, the sliding belt 334 on the rectangular flip plate 311 will slide in the opposite direction of the sliding of the rectangular flip plate 311 under the push of the spring rod 321.

[0084] The bottom of the spring plate 332 is rotatably connected to a plurality of arc-shaped plates 333 , which are arranged in pairs at equal distances. A sliding belt 334 is fixedly connected to the side of the sliding frame 331 away from the telescopic bracket 101 ;

[0085] The side of the sliding belt 334 away from the sliding frame 331 is fixedly connected to the side wall of the T-shaped frame 301;

[0086] Among them, a conical frame 302 is slidably connected between the two stepped wave grooves 313, and the top of the conical frame 302 is in contact with the bottom of the sliding belt 334. When the conical frame 302 swings up and down, the swing of the conical frame 302 can drive the sliding belt 334 to swing synchronously. At this time, the sliding belt 334 can be in close contact with the inclined frame 322 during the swing. At this time, when the sliding belt 334 swings, it can generate intermittent pulling force on the sliding frame 331, so that the sliding frame 331 can hook deep into the ground soil at the bottom arc.

[0087] When in use, first open the three telescopic brackets 101 and adjust the length of the telescopic brackets 101 according to the required height, then place it on the required ground and install the surveying instrument 4 on the top of the main body 1, then open the surveying instrument 4 to survey, and after the surveying is completed, fold up the telescopic brackets 101 and close the three telescopic brackets 101 so that the snap column 113 is inserted into the snap ring 112, and then the folded surveying device can be conveniently carried.

[0088] When the three telescopic brackets 101 are unfolded and placed on the ground, the unfolding of the telescopic bracket 101 will drive the folding plate 211 to unfold through the adjustment frame 111. At this time, the unfolding of multiple folding plates 211 can make the flexible layer 212 in a smooth state. At the same time, when the telescopic bracket 101 drives the folding plates 211 to unfold during the unfolding process, the unfolding of the folding plates 211 will drive the circular shaft 221 to slide downward. When the circular shaft 221 slides downward, the counterweight plate 122 will slide downward. Subsequently, when strong winds occur during the detection process, the flow of strong winds will flow through the surface of the flexible layer 212 when passing through the telescopic bracket 101, so that when the wind blows towards the bracket, it will be guided to flow upward under the inclination of the flexible layer 212, and at the same time, a downward pressure force will be exerted on the flexible layer 212 and the folding plate 211. When wind acts on the folding plate 211 and the flexible layer 212, the folding plate 211 will be subjected to downward pressure and will drive the circular shaft 221 to move downward. When multiple circular shafts 221 are subjected to downward pressure during the flow of strong winds, they can not only provide support between the three telescopic brackets 101, but also lower the overall center of gravity height of the device. At the same time, when wind blows towards the device, the counterweight plate 122 will drive the telescopic rod 121 to swing at the bottom of the main body 1 under the flow of wind. The multi-angle swing of the flexible layer 212 can absorb and dissipate the force acting on the telescopic bracket 101 during the wind flow, thereby reducing and suppressing the swing amplitude of the surveying instrument 4 during surveying, reducing the shaking or tilting caused by excessive force on one side in windy weather, thereby improving the surveying accuracy and stability during surveying.

[0089] When the circular shaft 221 moves downward, the long rod 222 will push the T-shaped frame 301 to slide downward. When the T-shaped frame 301 slides, it will push the rectangular flip plate 311 to flip downward on the side wall of the telescopic bracket 101. When the rectangular flip plate 311 flips downward, the sliding frame 331 will be inserted into the ground. Subsequently, when the entire device slides in strong winds during surveying, the sliding of the telescopic bracket 101 can drive the rectangular flip plate 311 to slide synchronously. Since the sliding frame 331 is inserted into the ground, when the telescopic bracket 101 drives the rectangular flip plate 311 to slide, the corresponding sliding frame 331 will drive the sliding belt 334 to rotate cyclically when the rectangular flip plate 311 slides. The sliding belt 334 is in a tightened state. At the same time, when the other two rectangular flip plates 311 slide, the sliding belt 334 on the rectangular flip plate 311 will slide in the opposite direction of the sliding of the rectangular flip plate 311 under the push of the spring rod 321, and can increase the contact area between the rectangular flip plate 311 and the ground. At the same time, the insertion of the sliding frame 331 into the ground can improve the grip between the device and the ground, thereby reducing the situation where the device is affected by large lateral wind forces during the process of guiding wind sliding during surveying and mapping, and thus can reduce the situation where the device slides due to the influence of large lateral wind forces. This dynamic adjustment mechanism further enhances the stability during surveying and mapping, maintains high surveying and mapping accuracy, and can also reduce data fluctuations during surveying and mapping.

[0090] When one of the rectangular flip plates 311 slides, the sliding belt 334 is in a tightened state, and the sliding of the rectangular flip plate 311 will cause the sliding frame 331 to drive the conical frame 302 to slide in the stepped wave groove 313 in the opposite direction of the sliding of the device when inserted into the ground. At this time, the sliding of the conical frame 302 will slide downward under the guidance of the inclined groove on the stepped wave groove 313. When the conical frame 302 slides downward, it will push the spring plate 332 to slide downward. When the spring plate 332 slides downward, it can push multiple arc plates 333 to extend out of the sliding frame 331 and insert into the interior of the ground to form a barb-like structure, thereby reducing the situation where the sliding frame 331 is separated from the ground and difficult to effectively insert due to the relatively soft soil of the ground when the device slides, thereby further enhancing the stability of the device's grip on the ground during surveying and mapping, and enhancing wind resistance efficiency.

[0091] When the other two rectangular flip plates 311 slide, the sliding belt 334 on the rectangular flip plate 311 will slide in the opposite direction of the sliding of the rectangular flip plate 311 under the push of the spring rod 321. At this time, the sliding frame 331 in the rectangular flip plate 311 will slide in the stepped wave groove 313 when the rectangular flip plate 311 slides. At this time, the conical frame 302 will rock up and down under the ups and downs in the stepped wave groove 313. When the conical frame 302 rocks up and down, the rocking of the conical frame 302 can drive the sliding belt 334 to rock synchronously. At this time, the sliding belt 334 can make close contact with the tilting frame 322 when shaking. At this time, the sliding belt 334 can generate intermittent pulling force on the sliding frame 331 when shaking, so that the sliding frame 331 can hook deep into the ground soil at the bottom arc, increasing the insertion depth. At the same time, it can also make the sliding belt 334 clean the soil attached to the sliding belt 334 under the contact with the tilting frame 322 when shaking, thereby reducing the situation where the sliding belt 334 and the ground slip due to the adhesion of soil and affect the grip, thereby enhancing the insertion depth and stability of the sliding frame 331 into the soil.
