Description

TECHNICAL FIELD

[0001] The application relates to the technical field of surveying equipment, in particular to a surveying device based on three-dimensional image surveying of building engineering. BACKGROUND

[0002] In the building engineering industry, the size of a building often needs to be measured, but direct detection is relatively troublesome due to the height of the building, so a three-dimensional image surveying method is usually used to measure the building.

[0003] A patent with the application number CN202420449962.4 discloses an image acquisition device. The image acquisition device comprises a fixed holder, a first connecting rod fixed to the top of the fixed holder, a fixed rod slidably connected to the top end of the first connecting rod, a rotating column rotatably connected to the top of the fixed rod, a fixed table fixed to the top of the rotating column, and a motion camera bolted to the top of the fixed table.

[0004] In the above-mentioned scheme, the detection instrument is directly installed on the holder, and the detection instrument is directly exposed to the external environment. When the weather changes, the detection instrument needs to be moved immediately. If the detection instrument is not moved in time, the detection instrument will be in contact with a large amount of liquid, which will affect the accuracy of the detection instrument in subsequent use.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned problems. CONTENT OF THE INVENTION

[0006] In order to prevent the detection instrument from being directly in contact with a large amount of liquid during use, the application provides a surveying device based on three-dimensional image surveying of building engineering.

[0007] The application provides a surveying device based on three-dimensional image surveying of building engineering, which adopts the following technical solution:

[0008] The surveying device based on three-dimensional image surveying of building engineering comprises a mounting seat, a detection instrument arranged on the mounting seat, a plurality of supporting feet arranged below the mounting seat, and a rain blocking assembly arranged on the mounting seat. The rain blocking assembly comprises two rain blocking pieces for blocking rainwater and a plurality of connecting pieces arranged on the rain blocking pieces. The rain blocking pieces abut each other and are arranged above the detection instrument to block the detection instrument. The connecting pieces are arranged at the ends of the rain blocking pieces away from each other. The lower ends of the connecting pieces are rotatably connected to the mounting seat, so that the two rain blocking pieces can move away from each other.

[0009] By adopting the above technical scheme, in rainy weather, the rain shield can be turned up to the upper side of the detection instrument, the upper space of the detection instrument is blocked by the blocking piece, so that the rainwater cannot directly fall on the detection instrument, and the detection instrument is not easily affected by the rainwater to reduce the detection accuracy.

[0010] Optionally, the side wall of each of the two rain shields close to each other is provided with a magnetic piece, and the magnetic pieces on the two rain shields can be attracted.

[0011] By adopting the above technical scheme, after the two rain shields abut against each other, the magnetic pieces are attracted to each other to apply a force close to each other to the two rain shields, so that the two rain shields can maintain the state of abutting against each other, thereby stably shielding the rainwater falling on the detection instrument.

[0012] Optionally, the side wall of each of the two rain shields close to each other is provided with a magnetic piece, and the magnetic pieces on the two rain shields can be attracted.

[0013] By adopting the above technical scheme, when the rain shield is not working to shield the rainwater, part of the objects required for surveying and mapping can be placed above the turned rain shield, so that part of the components can be placed, thereby making the surveying and mapping process more convenient.

[0014] Optionally, the edge of each of the two rain shields far away from the abutting center is inclined downward, the side wall of each of the two rain shields abutting against each other is provided with an extension piece extending in the direction of the inclined edge, and the extension piece is connected with the inclined position of the rain shield.

[0015] By adopting the above technical scheme, after the rainwater falls on the rain shield, the rainwater can flow along the slope above the rain shield towards the edge of the rain shield and drip from the edge of the rain shield, so that the upper side of the rain shield is not easy to accumulate rainwater.

[0016] Optionally, the side wall of each of the two rain shields close to each other is provided with a magnetic piece, and the magnetic pieces on the two rain shields can be attracted.

[0017] By adopting the above technical scheme, the gap between the two rain shields is filled by the sealing strip, and after the rain shields abut against each other, the gap between them can be reduced, thereby reducing the probability of rainwater flowing downward between the two rain shields, and making the rain shield have a better rain shielding effect.

[0018] Optionally, the blocking piece is rotationally connected to the mounting seat, an axis of rotation of the blocking piece is perpendicular to an axis of rotation of the connecting piece, the blocking piece can abut against a side wall of the connecting piece away from the detection instrument when the connecting piece is rotated to an upper end of the mounting seat, and the blocking piece can abut against the side wall of the connecting piece close to the detection instrument when the connecting piece is rotated to a lower end of the mounting seat.

[0019] By using the above technical solution, when the two rain blocking pieces abut against each other, the blocking piece can be rotated to the upper end of the mounting rack and abut against the connecting piece, so that the position of the connecting piece can be kept limited, and the adjacent rain blocking pieces can be kept stably abutted.

[0020] Optionally, the blocking piece includes a rotating block connected to the mounting seat and blocking blocks abutting against the connecting pieces in different states respectively, and the blocking blocks are arranged on both sides of the axis of rotation of the rotating block.

[0021] By using the above technical solution, the blocking blocks can abut against the connecting pieces in different states respectively, so that the position of the rain blocking piece can be limited when the rain blocking piece is located above the mounting seat or below the mounting seat.

[0022] Optionally, the blocking blocks are provided with guide inclined surfaces at positions away from the rotating block when abutting against the side wall of the connecting piece, the blocking blocks are provided with limiting grooves when abutting against the side wall of the connecting piece, and a part of the connecting piece can be embedded in the limiting groove.

[0023] By using the above technical solution, when the blocking block abuts against the connecting piece, the connecting piece can be embedded in the limiting groove, so that the relative position of the blocking block and the connecting piece can be limited, and the blocking block can stably limit the position of the rain blocking piece.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. In rainy weather, the rain blocking piece can be rotated upward to above the detection instrument, the space above the detection instrument is shielded by the blocking piece, so that the rainwater cannot directly fall on the detection instrument, and the detection instrument is not easily affected by the rainwater to cause the detection precision to be reduced.

[0026] 2. When the rain blocking piece does not shield the rainwater, some objects needed for surveying and mapping can be placed above the rain blocking piece after being turned over, so that some parts can have a place to be placed, thereby making the surveying and mapping process more convenient.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a surveying device based on three-dimensional image mapping of architectural engineering, such as... Figure 1 As shown, the system includes a mounting base 1, a detection instrument 2 mounted on the mounting base 1, three support legs 3 positioned below the mounting base 1, and a rainproof assembly 4 mounted on the mounting base 1. In this embodiment, the detection instrument 2 is a total station. The instrument 2 is mounted on the mounting base 1, allowing it to rotate and observe targets as needed. The support legs 3 are circumferentially positioned at the lower end of the mounting base 1, with their upper ends rotatably connected to the lower end face of the mounting base 1. The angles between adjacent support legs 3 and the rotation axis of the mounting base 1 are the same. The rainproof assembly 4 includes two rainproof components 41 for blocking rainwater and several connecting pieces 42 connecting the rainproof components 41 to the mounting base 1. Each rainproof component 41 is connected to two connecting pieces 42. The rainproof components 41 shield the detection instrument 2 from rainwater moving towards it, reducing the amount of contact between the instrument 2 and water, thus minimizing the impact on the detection accuracy of the instrument 2.

[0033] The rain shield 41 is horizontally positioned above the testing instrument 2. Two adjacent rain shields 41 are positioned so that their ends abut against each other, covering the entire upper part of the testing instrument 2 and thus blocking rainwater as it moves towards the instrument. Connecting pieces 42 are positioned near the two corners of the rain shields 41, away from the corners they abut against. The connecting pieces 42 are perpendicular to and fixedly connected to the rain shields 41. The end of the connecting piece 42 away from the rain shield 41 is rotatably connected to the mounting base 1, and the rotation axes of the two rain shields 41 are parallel. When the rain shields 41 are not needed, they can be rotated away from each other, allowing them and the connecting pieces 42 to be positioned away from the testing instrument 2, minimizing disruption to its normal operation. During rain, the two rain shields 41 can be brought closer together, working together to block rainwater falling towards the testing instrument 2.

[0034] likeFigure 2 As shown, in order to keep the relative position of the two rain barriers 41 defined after the two rain barriers 41 abut against each other, the side wall of the two rain barriers 41 abutting against each other is embedded with a magnetic member 43, the magnetic poles of the magnetic members 43 arranged on the two rain barriers 41 are opposite to each other, so that the magnetic members 43 arranged on the two rain barriers 41 can be attracted to each other after the two rain barriers 41 abut against each other, thereby keeping the rain barriers 41 in the abutting state.

[0035] As shown, Figure 3 The lower portion of the mounting base 1 is further provided with four blocking members 5, which can abut against the side wall of the connecting member 42 close to the axis of the mounting base 1 when the connecting member 42 is rotated downward, so that the rain barriers 41 can be flipped to the horizontal state, and the objects needed in the surveying process can be directly placed on the rain barriers 41, making the surveying process more convenient.

[0036] The blocking member 5 includes a rotating block 51 and a blocking block 52 capable of abutting against the connecting member 42 in different states. The rotating block 51 is rotationally connected to the mounting base 1, and the rotation axis of the rotating block 51 is perpendicular to the rotation axis of the connecting member 42. The blocking block 52 is arranged on both sides of the rotation axis of the rotating block 51. When the connecting rod is above the mounting base 1, the rotating block 51 is rotated upward to the vertical state, and the blocking block 52 abuts against the side wall of the connecting rod away from the detector instrument 2, so that the two rain barriers 41 can be kept abutting. When the connecting rod is rotated to the lower portion of the mounting base 1, the rotating block 51 is rotated downward, and the blocking block 52 abuts against the side wall of the connecting rod close to the detector instrument 2, so that the rain barriers 41 separated from each other can be kept in the horizontal state stably, and the objects placed on the rain barriers 41 are not easy to fall off.

[0037] The blocking block 52 is provided with a guide slope 521 at the position of the side wall of the connecting member 42 away from the rotating block 51, which can abut against the connecting member 42, so that the connecting member 42 can be moved to the side wall of the blocking block 52 during the movement of the rotating block 51. The blocking block 52 is further provided with a limiting groove 522 for limiting the position of the connecting member 42, which penetrates the upper and lower end faces of the blocking block 52, and a part of the connecting member 42 can be embedded in the limiting groove 522, so that the blocking block 52 can be kept connected with the connecting member 42 stably, and the blocking member 5 can limit the position of the connecting member 42 stably.

[0038] In order to make the rainwater flow down along the edge of the rain shield 41 more easily when the rain shield 41 blocks the rainwater, the three edges of the two abutting rain shields 41 away from the axis of the mounting base 1 are all inclined towards the mounting base 1, so that the rain shield 41 is inclined downward except the abutting side walls, and when the rainwater falls on the rain shield 41, the rainwater is more likely to flow down along the upper end surface of the rain shield 41 which is inclined downward.

[0039] As shown in Figure 2 When the rain shield 41 is inclined, the upper end surface of the rain shield 41 will form a downward recessed space for placing objects after the rain shield 41 is turned downward, and the end of the rain shield 41 away from the connecting piece 42 will form a gap, which is easy to cause the objects to fall from the gap. Therefore, the abutting side walls of the rain shield 41 are integrally formed with an extension piece 411 which is connected with the two inclined side walls of the rain shield 41. The side wall of the extension piece 411 away from the side wall of the rain shield 41 is flush with the inclined side wall of the rain shield 41, so as to block the objects flowing from the gap of the rain shield 41 by the extension piece 411, and the objects placed in the rain shield 41 can be placed and blocked on the rain shield 41.

[0040] Since there is still a gap between the adjacent rain shields 41 after the abutting, the rainwater can still flow down along the gap between the adjacent rain shields 41, therefore, the side walls of the adjacent extension pieces 411 close to each other are all provided with a sealing strip 44 which is made of rubber, and the adjacent sealing strips 44 can abut each other, so as to fill the gap between the rain shields 41, reduce the gap between the rain shields 41, and make the rain shield 41 better block the rainwater and the like, so that the detection instrument 2 is not easy to contact with the rainwater.

[0041] The implementation principle of the embodiment is that when the detection instrument 2 is used for measurement, the rotating block 51 is rotated to the lower side of the mounting base 1, then the two rain shields 41 are turned away from each other and downward, the connecting piece 42 abuts on the blocking block 52, so that the detection instrument 2 can be normally used, and the objects required for surveying and mapping can be placed on the rain shield 41. When it rains, the rain shield 41 is first turned upward to abut the two rain shields 41, then the rotating block 51 is turned upward, so that the blocking block 52 abuts on the connecting piece 42 to block the rainwater falling on the detection instrument 2.

[0042] The embodiments of the specific embodiment are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
