Description

Technical Field

[0001] The present invention relates to the technical field of surveying equipment, in particular to a surveying equipment for land reclamation. Background Art

[0002] Land consolidation refers to the process of comprehensively improving and developing fields, waterways, roads, forests, and villages within a specific area, in accordance with the objectives and uses determined by the overall land use plan, urban planning, and special land consolidation plans. This involves the use of administrative, economic, and legal means, as well as engineering measures. This involves the in-depth development of improperly allocated, irrationally utilized, scattered, idle, and underutilized rural settlement land, with the goal of increasing intensive land use and productivity, improving production and living conditions, and the ecological environment. Land consolidation, in a broad sense, encompasses land consolidation, land reclamation, and land development. Surveying equipment, such as total stations and theodolites, is often used for land consolidation.

[0003] In the prior art, the use of measuring equipment such as theodolites requires the support of a tripod at the bottom. Since outdoor land measurement involves a large number of measuring points, the theodolite needs to be moved to the next measuring point after each measuring point is completed. During this process, if the theodolite is to be retracted, it needs to be disassembled from the tripod first, and then reinstalled when it reaches the next measuring point. If the theodolite is not retracted, it is easy for the theodolite to be damaged by collision or dust during transportation in an outdoor environment. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a surveying equipment for land reclamation to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The three sets of telescopic legs at the bottom of the base do not need to be separated from the theodolite after the measurement is completed. Through the cooperation of the rotating assembly and the enclosure assembly, the theodolite is wrapped and stored, which has a certain anti-collision and dust-proof effect. At the same time, it is convenient to carry and use quickly outdoors, saving the inconvenience of repeatedly disassembling and storing the theodolite.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solution: a surveying device for land reclamation, comprising a base, a theodolite is mounted on the top of the base, a stud is fixed to the bottom of the theodolite, a screw hole is opened on the base, and the stud is threadedly inserted into the screw hole, a slide plate is fixed to the bottom of the base, and three groups of sliding shaft seats are slidably connected to the outer side of the slide plate, and telescopic legs are rotatably mounted on the outer side of the sliding shaft seat, and a side plate of the sliding shaft seat is provided with a rotating assembly, and the rotating assembly includes a gear, and the gear is fixedly connected to the rotating connecting shaft of the telescopic legs and the sliding shaft seat, and a gear plate is meshed with one side of the gear, and an enclosure assembly is provided on the outer ring of the top of the base, and the enclosure assembly includes a storage frame, which is circular and fixed to the top of the base, and an elastic cover is folded and stored inside the storage frame, a first rotating plate and a second rotating plate are provided on the top of the theodolite, and the middle position of the first rotating plate and the second rotating plate is rotatably connected by a bearing, and plug plates are provided at both ends of the first rotating plate, and the plug plates are plugged into the top of the elastic cover.

[0006] Furthermore, a sliding seat is fixed to the bottom of the sliding shaft seat, and the sliding seat slides along the bottom of the slide rail plate. A first bolt is inserted into the outer thread of the sliding seat, and the first bolt is in compression contact with the bottom surface of the slide rail plate.

[0007] Furthermore, a rubber band is fixed between adjacent sliding shaft seats, a second bolt is threadedly inserted into the extended end of the telescopic leg, and the second bolt is in compression contact with the extended end of the telescopic leg.

[0008] Furthermore, the rotating assembly also includes a ring, the outer periphery of the storage frame is slidably sleeved with the ring, a plurality of electric push rods are equidistantly fixed on the top of the outer wall of the storage frame, and the extended ends of the electric push rods are fixedly connected to the ring.

[0009] Furthermore, a transverse plate is slidably sleeved on the top of the tooth plate, and a buckle frame is fixed on the side of the transverse plate facing the circular ring. The buckle frame is slidably sleeved on the surface of the circular ring, and a third bolt is inserted into the outer thread of the transverse plate, and the third bolt is in extrusion contact with the tooth plate.

[0010] Furthermore, a limit frame is fixed on the outer wall of the sliding shaft seat, and the tooth plate is slidably inserted into the limit frame.

[0011] Furthermore, the enclosure assembly also includes a top ring, a top ring is fixed on the top of the elastic cover, two sockets are fixed on the outer side of the storage end of the telescopic leg corresponding to the position of the top ring, and the sockets are slidably inserted on the surface of the top ring.

[0012] Furthermore, movable grooves are provided at the tops of both ends of the first rotating plate, and push blocks are slidably connected inside the movable grooves. The push blocks are fixedly connected to the plug plates, and the plug plates are slidably plugged into the inner wall of the top ring.

[0013] Furthermore, a storage slot is provided on the top of the theodolite, and a spring telescopic rod is fixed at the middle position inside the storage slot, and the extended end of the spring telescopic rod is rotatably connected to the middle bottom of the second rotating plate through a bearing.

[0014] Furthermore, four arc-shaped folding films are fixed on both sides of the second rotating plate and the first rotating plate, and a lifting handle is fixed on the top of the first rotating plate.

[0015] Beneficial effects of the present invention:

[0016] 1. When the first rotating plate and the second rotating plate of the present invention rotate into a cross shape, the folding membrane unfolds and cooperates with the first rotating plate and the second rotating plate to form a circular shielding cover, thereby providing a certain degree of dustproof and waterproof protection for the top of the theodolite. When the first rotating plate and the second rotating plate rotate into a folded shape, the elastic force of the spring telescopic rod retracts the two rotating plates into the storage groove, making it easy to release the clamping connection between the first rotating plate and the top ring, thereby exposing the theodolite on the base for use.

[0017] 2. When the elastic cover is unfolded, the first and second rotating plates are manually pulled out of the storage slots and rotated into a cross shape. The second rotating plate is pressed into contact with the top of the theodolite, pushing the push blocks on both sides of the first rotating plate to slide along the movable slots. The inserting plate is inserted into the slot on the inner side of the top ring, realizing the horizontal engagement between the first rotating plate and the top ring, and coordinating with the vertical engagement between the telescopic legs and the top ring to form a stable structure.

[0018] 3. The present invention uses the lifting handle on the top of the first rotating plate to carry the theodolite. The sockets of the telescopic legs are elastic and can produce a certain degree of deformation, the same as the outer edge of the circular ring. Therefore, the sockets and the top ring can be plugged and locked by extrusion deformation. When unlocked, the elastic cover is stored inside the storage frame to avoid interfering with the normal use of the theodolite. When the theodolite is stored, the top ring is manually pulled upward to expand the elastic cover to wrap the theodolite.

[0019] 4. The present invention drives the circular ring to move upward by an electric push rod, and the horizontal plate drives the tooth plate to slide upward along the limit frame. The tooth plate is engaged with the gear, so that the telescopic legs are changed from an upward vertical state to a downward vertical state. Then the position of the third bolt is unlocked, and the angle of each telescopic leg is adjusted individually. The angle is adjusted by the engagement of the tooth plate and the gear. After determining the angle of each individual telescopic leg, it is locked by the third bolt, so that the device can be corrected to a horizontal state on an uneven ground. At the same time, when the theodolite needs to be stored, the telescopic legs are uniformly reset to a downward vertical state, and then the circular ring is driven downward by the electric push rod, the tooth plate is uniformly slid downward along the limit frame, and the telescopic legs are rotated to the same angle to the top of the base, and the theodolite is wrapped in conjunction with the expansion of the elastic cover.

[0020] 5. The telescopic legs of the present invention slide along the slide rail disk through the sliding shaft seat and the slide seat to maintain stability. There are rubber bands between adjacent legs. In the absence of external force, the positions of the three groups of telescopic legs are equidistantly arranged around the slide rail disk, which is convenient for forming a stable outer frame structure with the top ring and the first rotating plate. When the position of the telescopic legs needs to be adjusted according to the terrain, the sliding shaft seat is manually pulled to slide along the surface of the slide rail disk. The rubber band can be elastically stretched and retracted at this time. After the position is determined, its position is locked by the first bolt. Therefore, the position of the three telescopic legs is more flexible and can be adjusted and used according to the outdoor terrain, which is convenient for faster correction of the level. The length of the telescopic legs is adjusted after unlocking the second bolt, and locked by the second bolt after the length is determined.

[0021] 6. Compared with the prior art, the three sets of telescopic legs at the bottom of the base of the present invention do not need to be separated from the theodolite after the measurement is completed. The theodolite can be wrapped and stored by cooperating with the rotating assembly and the enclosure assembly, which has a certain anti-collision and dust-proof effect. At the same time, it is convenient for quick carrying and use outdoors, saving the inconvenience of repeatedly disassembling and storing the theodolite. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] See also Figures 1 to 8The present invention provides a technical solution: a land reclamation surveying device, comprising a base 1, a theodolite 2 is mounted on the top of the base 1, a stud 21 is fixed to the bottom of the theodolite 2, a screw hole 12 is provided on the base 1, and the stud 21 is threadedly inserted into the screw hole 12, a slide plate 11 is fixed to the bottom of the base 1, and three sets of sliding shaft seats 31 are slidably connected to the outer side of the slide plate 11, and a telescopic support leg 3 is rotatably mounted on the outer side of the sliding shaft seat 31, and the sliding shaft seat 31 is provided with a telescopic support leg 3. The side panel is provided with a rotating assembly 4, which includes a gear 43. The gear 43 is fixedly connected to the rotating connecting shaft of the telescopic leg 3 and the sliding shaft seat 31. One side of the gear 43 is meshed with a toothed plate 44. The outer ring of the top of the base 1 is provided with an enclosure assembly 5. The enclosure assembly 5 includes a storage frame 51. The storage frame 51 is circular and fixed to the top of the base 1. The storage frame 51 is folded inside to accommodate an elastic cover 53. The top of the theodolite 2 is provided with a first rotating plate 22 and a second rotating plate 24. The middle position of the first rotating plate 22 and the second rotating plate 24 is rotatably connected by a bearing. Insert plates 28 are provided at both ends of the first rotating plate 22, and the insert plates 28 are inserted into the top of the elastic cover 53. When the device is in use, the bottom of the theodolite 2 is screwed to the base 1 by the studs 21. The angle and length are adjusted after the three sets of telescopic legs 3 are unfolded. The device is placed on the ground and the horizontal position is corrected using an existing level. Then, the angle of the terrain is measured by the theodolite 2. When the measurement is completed and the point needs to be changed, the telescopic legs 3 are rotated to the top of the base 1. The elastic cover 53 of the enclosure assembly 5 is unfolded to wrap the outside of the theodolite 2 and is locked with the first rotating plate 22 and the telescopic legs 3. This reduces the size of the device, makes it easier to carry and transport, and protects the theodolite 2 from dust and water. It also provides a certain degree of anti-collision protection. In this solution, the protection of the theodolite 2 by the enclosure assembly 5 is limited to simple protection during the transfer process of multi-point measurement. For more convenient transportation, after the measurement is completed, the theodolite 2 is separated from the base 1 and stored.

[0033] In this embodiment, a sliding seat 34 is fixed to the bottom of the sliding shaft seat 31, and the sliding seat 34 slides along the bottom of the slide rail plate 11. The outer side of the sliding seat 34 is threaded with a first bolt 35, and the first bolt 35 is in extrusion contact with the bottom surface of the slide rail plate 11. A rubber band 32 is fixed between adjacent sliding shaft seats 31. The extended end of the telescopic leg 3 is threaded with a second bolt 36, and the second bolt 36 is in extrusion contact with the extended end of the telescopic leg 3. The telescopic leg 3 slides along the slide rail plate 11 through the sliding shaft seat 31 and the sliding seat 34 to maintain stability. There is a rubber band 32 between adjacent ones, so that in the absence of external force, Under normal circumstances, the positions of the three groups of telescopic legs 3 are equidistantly arranged around the slide rail plate 11, which is convenient for forming a stable outer frame structure with the top ring 52 and the first rotating plate 22. When the position of the telescopic leg 3 needs to be adjusted according to the terrain, the sliding shaft seat 31 is manually pulled to slide along the surface of the slide rail plate 11. The rubber band 32 can be elastically stretched and retracted at this time. After the position is determined, its position is locked by the first bolt 35. Then, the position of the three telescopic legs 3 is more flexible and can be adjusted according to the outdoor terrain, which is convenient for faster correction of the level. The length of the telescopic leg 3 is adjusted after unlocking by the second bolt 36, and locked by the second bolt 36 after the length is determined.

[0034] In this embodiment, the rotating assembly 4 also includes a circular ring 42, and the outer periphery of the storage frame 51 is slidably sleeved with the circular ring 42. A plurality of electric push rods 41 are equidistantly fixed to the top of the outer wall of the storage frame 51, and the extended ends of the electric push rods 41 are fixedly connected to the circular ring 42. The top of the tooth plate 44 is slidably sleeved with a transverse plate 46, and a buckle frame 47 is fixed to the side of the transverse plate 46 facing the circular ring 42. The buckle frame 47 is slidably sleeved on the surface of the circular ring 42, and the outer side of the transverse plate 46 is threadedly inserted with a third bolt 48, and the third bolt 48 is in extrusion contact with the tooth plate 44. A limit frame 45 is fixed on the outer wall of the sliding shaft seat 31, and the tooth plate 44 is slidably inserted inside the limit frame 45. The circular ring 42 is driven to move upward by the electric push rod 41, and the transverse plate 46 drives the tooth plate 44 to move uniformly along the circular ring 42. The limit frame 45 slides upward, and the tooth plate 44 engages with the gear 43, so that the telescopic leg 3 changes from an upward vertical state to a downward vertical state. Then the position of the third bolt 48 is unlocked, and the angle of each telescopic leg 3 is adjusted individually. The angle is adjusted by the engagement of the tooth plate 44 with the gear 43. After determining the angle of each individual telescopic leg 3, it is locked by the third bolt 48, so that the device can be corrected to a horizontal state on an uneven ground. At the same time, when the theodolite 2 needs to be stored, the telescopic legs 3 are uniformly reset to a downward vertical state, and then the electric push rod 41 drives the ring 42 to move downward, and the tooth plate 44 slides downward along the limit frame 45. The telescopic legs 3 rotate to the same angle to the top of the base 1, and the elastic cover 53 is unfolded to wrap the theodolite 2.

[0035] In this embodiment, the enclosure assembly 5 also includes a top ring 52, and a top ring 52 is fixed on the top of the elastic cover 53. Two sockets 33 are fixed on the outer side of the storage end of the telescopic leg 3 corresponding to the position of the top ring 52, and the sockets 33 are slidably plugged into the surface of the top ring 52. A movable groove 26 is opened on the top of both ends of the first rotating plate 22, and a push block 27 is slidably connected inside the movable groove 26. The push block 27 is fixedly connected to the plug plate 28, and the plug plate 28 is slidably plugged into the inner wall of the top ring 52. When the elastic cover 53 is unfolded, the first rotating plate 22 and the second rotating plate 24 are manually pulled out from the storage groove 29, and the first rotating plate 22 and the second rotating plate 24 are rotated into a cross shape. The second rotating plate 24 is squeezed and contacted with the top of the theodolite 2, pushing the first rotating plate 22 The push blocks 27 on both sides slide along the movable grooves 26 and insert the inserting plate 28 into the slot inside the top ring 52, thereby realizing the horizontal clamping of the first rotating plate 22 and the top ring 52, and cooperating with the vertical clamping of the telescopic legs 3 and the top ring 52 to form a stable structure. The theodolite 2 is carried and moved by the lifting handle 23 on the top of the first rotating plate 22. The socket 33 of the telescopic legs 3 is elastic and can produce a certain degree of deformation, which is the same as the outer edge of the ring 42. Therefore, the socket 33 and the top ring 52 can be plugged and locked by extrusion deformation. The elastic cover 53 is stored inside the storage frame 51 when it is not locked to avoid interfering with the normal use of the theodolite 2. When the theodolite 2 is stored, the top ring 52 is manually pulled upward, and the elastic cover 53 is unfolded to wrap the theodolite 2.

[0036] In this embodiment, a storage groove 29 is provided on the top of the theodolite 2, and a spring telescopic rod 210 is fixed in the middle position of the storage groove 29. The extended end of the spring telescopic rod 210 is rotatably connected to the middle bottom of the second rotating plate 24 through a bearing. Four arc-shaped folding films 25 are fixed on both sides of the second rotating plate 24 and the first rotating plate 22. A lifting handle 23 is fixed on the top of the first rotating plate 22. The folding films 25 are actually stored between the first rotating plate 22 and the second rotating plate 24. When the first rotating plate 22 and the second rotating plate 24 are rotated into a cross shape, the folding films 25 unfold and cooperate with the first rotating plate 22 and the second rotating plate 24 to form a circular shielding cover, providing a certain degree of dust and water protection for the top of the theodolite 2. When the first rotating plate 22 and the second rotating plate 24 are rotated into a folded shape, the two rotating plates are stored back into the storage groove 29 by the elastic force of the spring telescopic rod 210, which facilitates the release of the clamping of the first rotating plate 22 and the top ring 52, thereby exposing the theodolite 2 on the base 1 for use.

[0037] When the device is in use, the bottom of the theodolite 2 is threadedly fixed to the base 1 by the stud 21, and the telescopic legs 3 slide along the slide plate 11 through the sliding shaft seat 31 and the slide seat 34 to maintain stability. There are rubber bands 32 between adjacent ones, so that in the absence of external force, the positions of the three groups of telescopic legs 3 are equidistantly arranged around the slide plate 11, which is convenient for forming a stable outer frame structure with the top ring 52 and the first rotating plate 22. When it is necessary to adjust the position of the telescopic legs 3 according to the terrain, the sliding shaft seat 31 is manually pulled to slide along the surface of the slide plate 11. The rubber band 32 can be elastically extended and retracted at this time, and its position is locked by the first bolt 35 after the position is determined. Therefore, the position of the three telescopic legs 3 is relatively flexible and can be adjusted according to the outdoor terrain, which is convenient for faster calibration. When the level is correct, the length of the telescopic leg 3 is adjusted by unlocking the second bolt 36. After the length is determined, it is locked by the second bolt 36. The device is placed on the ground and the horizontal position is corrected using an existing level. The angle of the terrain is then measured by the theodolite 2. When the measurement is completed and the point needs to be changed, the circular ring 42 is driven upward by the electric push rod 41, and the horizontal plate 46 drives the tooth plate 44 to slide upward along the limit frame 45. The tooth plate 44 is engaged with the gear 43, so that the telescopic leg 3 is changed from an upward vertical state to a downward vertical state. Then the position of the third bolt 48 is unlocked, and the angle of each telescopic leg 3 is adjusted individually. The angle is adjusted by engaging the tooth plate 44 with the gear 43. After determining the angle of each individual telescopic leg 3, it is locked by the third bolt 48. The device can be kept in a horizontal state on an uneven ground. At the same time, when the theodolite 2 needs to be stored, the telescopic legs 3 are uniformly reset to a downward vertical state, and then the circular ring 42 is driven downward by the electric push rod 41. The toothed plate 44 uniformly slides downward along the limit frame 45, and the telescopic legs 3 rotate to the same angle to the top of the base 1, and the elastic cover 53 is unfolded to wrap the theodolite 2. When the elastic cover 53 is unfolded, the first rotating plate 22 and the second rotating plate 24 are manually pulled out from the storage groove 29, and the first rotating plate 22 and the second rotating plate 24 are rotated into a cross shape. The second rotating plate 24 is squeezed and contacted with the top of the theodolite 2, pushing the push blocks 27 on both sides of the first rotating plate 22 to slide along the moving groove 26, and inserting the inserting plate 28 into the top ring 52. The first rotating plate 22 and the top ring 52 are laterally connected inside the slot on the side, and the telescopic legs 3 are vertically connected with the top ring 52 to form a stable structure. The theodolite 2 is carried and moved by the lifting handle 23 on the top of the first rotating plate 22. The socket 33 of the telescopic legs 3 is elastic and can produce a certain degree of deformation, which is the same as the outer edge of the ring 42. Therefore, the socket 33 and the top ring 52 can be plugged and locked by extrusion deformation. The elastic cover 53 is stored in the storage frame 51 when it is not locked to avoid interfering with the normal use of the theodolite 2. When the theodolite 2 is stored, the top ring 52 is manually pulled upward, and the elastic cover 53 is unfolded to wrap the theodolite 2. The folding membrane 25 is actually stored between the first rotating plate 22 and the second rotating plate 24.When the first rotating plate 22 and the second rotating plate 24 rotate into a cross shape, the folding membrane 25 unfolds and cooperates with the first rotating plate 22 and the second rotating plate 24 to form a circular shield, providing a certain degree of dust and water protection for the top of the theodolite 2. When the first rotating plate 22 and the second rotating plate 24 rotate into the folded shape, the elastic force of the spring telescopic rod 210 retracts the two rotating plates into the receiving groove 29, conveniently releasing the clamping connection between the first rotating plate 22 and the top ring 52, thereby exposing the theodolite 2 on the base 1 for use. This reduces the size of the device, making it easier to carry and transport, and protects the theodolite 2 from dust and water, as well as providing a certain degree of anti-collision protection.
