Description

Technical Field

[0001] The present invention relates to the technical field of total stations, and more specifically, to a surveying and mapping geographic information total station for protection against rainy seasons. Background Art

[0002] At present, the total station is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance and height difference measurement functions. The total station is usually used in conjunction with a supporting structure. When used in geotechnical engineering surveys, the supporting structure needs to be supported on the ground first. The supporting structure supports the total station, and the total station is used to measure the required data.

[0003] Although existing total stations can perform effective surveying and mapping operations, when it rains during geotechnical engineering survey operations, rainwater enters the total station, making the internal parts of the total station easily damp, resulting in the service life of the total station being affected.

[0004] After searching, a Chinese patent with authorization announcement number CN114858145A discloses a total station with rainproof function. The instrument body is located in the space formed by the mounting plate and two side panels, which can block part of the rain. At the same time, the rain shield can be pulled down so that the rain shield cover is arranged outside the lens to reduce rain splashing into the space formed by the mounting plate and the side panels. At the same time, the setting of the window will not affect the lens measurement, thereby reducing the impact of rain on the service life of the total station. In addition, the rotating shaft drives the driving component to move, so that the driving component drives the limit block to move upward, and the upper end of the limit block is passed through the locking block. At the same time, the positioning component abuts against the limit block to limit the limit block from moving downward, thereby further limiting the movement of the locking block. When the locking block needs to be removed from the locking groove, the rotating shaft can continue to be rotated, and the rotating shaft drives the separation component to move. The separation component separates the positioning component from the limit block, so that the limit block loses the restriction of the positioning component and moves downward, so that the limit block is separated from the locking block.

[0005] However, when this structure is actually used, when the rain shield is pulled down for use, it is easy for the rain shield to get stuck or deflect when it moves downward directly through the storage slot, resulting in a large gap between the rain shield cover and the side panel. Rainwater can easily enter the space formed by the mounting plate and the side panel through these gaps, thereby affecting the operation of the internal instrument body and weakening the overall rain protection effect. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surveying and mapping geographic information total station with rainy season protection to solve the problems raised in the above-mentioned background technology.

[0017] Technical effects and advantages of the present invention:

[0018] 1. By setting up a rainproof mechanism, compared with the existing technology, the rainproof cloth and the supporting magnetic suction, slider and other structures can be quickly unfolded to form a reliable rainproof barrier when it rains. The sealing ring enhances the sealing performance, prevents rainwater from penetrating from the side gaps, protects the total station body from rain erosion, maintains an internal dry environment, is conducive to the stable operation of the instrument, and prolongs the service life. In addition, the operator only needs to control the forward and reverse rotation of the motor with one button to realize the unfolding and folding of the rainproof cloth. The counterweight bar, slider and other cooperation ensure smooth and accurate movement. When the rainproof cloth is not folded, the instrument status can be checked at any time with the help of a transparent PVC film, which is convenient for use;

[0019] 2. By setting up a connecting mechanism, compared with the existing technology, through the carefully designed connecting mechanism, when closing the rear door, first let the wire pass through the arc-shaped sealing strip, and then through multiple steps of operation to make the components closely fit, the arc-shaped sealing strip can effectively fill the gap, and the synergistic effect of the L-shaped stabilizing strip, shifting plate, etc. ensures that the connecting holes are accurately aligned, which greatly enhances the sealing of the rear door of the protective box, and can effectively block the invasion of external rain and impurities, creating a clean and dry internal environment for the total station body, ensuring its normal use and stable performance.

[0020] 3. By setting up a protective box, a top plate, guide grooves and support legs, compared with the existing technology, the top plate on the top of the protective box plays a key role during rainfall. It can catch the falling rainwater, and the guide grooves on the surface cleverly guide the rainwater to flow in a specific direction, effectively avoiding the accumulation of water, greatly reducing the risk of rainwater penetrating into the protective box through the gaps. The bottom support legs firmly support the protective box, so that the protective box forms a certain distance from the ground, which can isolate the ground from water, moisture and dirt. At the same time, the heat conduction plate in the heat dissipation box can promptly conduct the heat generated by the small stepper motor to ensure the stability of the overall work, and fully assist the total station to carry out surveying and mapping work smoothly in the rainy season and reduce interference from environmental factors.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The embodiments of this application disclose Figure 1-8 The surveying and mapping geographic information total station for rainy season protection shown in the figure comprises a protection box 1, a fixed tray 2 is fixedly arranged at the bottom of the protection box 1, a total station body 3 is fixedly installed inside the protection box 1, and a rainproof mechanism is arranged on one side of the protection box 1;

[0032] The rainproof mechanism includes a fixed frame 4 fixedly arranged on one side of the protection box 1, a heat dissipation box 5 is fixedly arranged on one side of the fixed frame 4, a heat conduction plate is embedded in the bottom of the heat dissipation box 5, a small stepping motor 6 is fixedly arranged inside the heat dissipation box 5, a winding rod 7 is fixedly arranged on the output end of the small stepping motor 6, a rainproof cloth 8 is arranged on the surface of the winding rod 7, a counterweight bar 9 is fixedly arranged on one end of the rainproof cloth 8, two T-shaped sliders 10 are fixedly arranged on one side of the counterweight bar 9, two slide grooves are provided on the surface of the protection box 1, the T-shaped slider 10 is slidably connected with the slide groove, a first magnetic strip 11 is fixedly arranged on the bottom of the counterweight bar 9, a fixed plate 12 is fixedly arranged on one side of the protection box 1, a second magnetic strip 13 is embedded in the surface of the fixed plate 12, a through groove is provided on the surface of the fixed frame 4, and the rainproof cloth 8 is slidably connected with the through groove. When it starts When it rains and the total station body 3 needs to be protected from rain, the operator starts the small stepper motor 6 in the heat dissipation box 5. A heat conducting plate is embedded in the bottom of the heat dissipation box 5. The heat conducting plate absorbs the heat generated by the small stepper motor 6 inside the heat dissipation box 5 when it is working, and conducts it outward to ensure normal heat dissipation of the small stepper motor 6. The small stepper motor 6 drives the winding rod 7 fixed at its output end to rotate clockwise. Since one end of the rainproof cloth 8 is firmly fixed to the surface of the winding rod 7, as the winding rod 7 rotates clockwise, the rainproof cloth 8 is gradually released from the winding rod 7 and unfolded. In this process, the rainproof cloth 8 slides downward along the through groove opened on the surface of the fixed frame 4. The through groove guides and constrains the movement direction of the rainproof cloth 8, ensuring that the rainproof cloth 8 can accurately unfold downward to cover one side of the protective box 1.

[0033] Reference Figure 2-4 As shown, one end of the winding rod 7 passes through the heat dissipation box 5 and the fixed frame 4 in sequence and is rotatably connected to the inner wall of the fixed frame 4, one end of the rainproof cloth 8 is fixedly connected to the surface of the winding rod 7, and the rainproof cloth 8 can be wound around the outside of the winding rod 7. The surface of the winding rod 7 is sleeved with two limit plates 14, and the surfaces of the two limit plates 14 are connected to the inner wall of the fixed frame 4. The fixed plate 12 is magnetically connected to the second magnetic strip 13. A through hole is opened on the surface of the rainproof cloth 8, and a transparent PVC film 15 is fixedly set inside the through hole. A sealing ring 16 is fixedly set on one side of the rainproof cloth 8. At the same time, the counterweight bar 9 fixed at one end of the rainproof cloth 8 is Under the action of its own gravity, the two T-shaped sliders 10 on one side slide smoothly downward along the slide groove on the surface of the protection box 1. The cooperation between the T-shaped slider 10 and the slide groove not only ensures the linearity of the sliding of the counterweight bar 9, but also prevents it from deviating left and right during the sliding process. When the counterweight bar 9 slides down to the position of the fixed plate 12 on one side of the protection box 1, the first magnetic strip 11 at the bottom of the counterweight bar 9 and the second magnetic strip 13 embedded in the surface of the fixed plate 12 attract each other and fit tightly together, so that the counterweight bar 9 is fixed at this position. At this point, the rainproof cloth 8 is fully unfolded, covering one side of the protection box 1, forming a rainproof barrier;

[0034] The transparent PVC film 15 fixed in the through hole opened on the surface of the rainproof cloth 8 can be used by the operator to view the display screen and operation buttons of the total station body 3 through it, so as to understand the working status of the total station body 3 without retracting the rainproof cloth 8, and can prevent rain from directly contacting the total station body 3 without affecting the optical observation of the total station body 3. The sealing ring 16 on one side of the rainproof cloth 8 will fit tightly against the surface of the protection box 1, further enhancing the sealing between the rainproof cloth 8 and the protection box 1, and effectively preventing rain from seeping into the inside of the protection box 1 through the gap between the two. When the rain stops or the rainproof cloth 8 is no longer needed for protection, the above steps are reversed to operate, and the entire rainproof cloth 8 is retracted, waiting to be unfolded and used again when rain protection is needed next time.

[0035] Reference Figure 5-6 As shown, a connecting mechanism is provided on one side of the protection box 1, and the connecting mechanism includes a rear door 17 hingedly provided on one side of the protection box 1, an L-shaped connecting strip 18 is rotatably provided on one side of the rear door 17, and a connecting frame is clamped on one side of the L-shaped connecting strip 18, and two mounting grooves 19 are provided on the surface of the rear door 17, and a movable groove is provided inside the rear door 17, and a shift plate 20 is slidably provided inside the movable groove, and connecting holes are provided on the surfaces of the shift plate 20 and the rear door 17, and arc-shaped sealing strips 21 are fixedly provided inside the connecting holes, and two stabilizing frames 22 are fixedly provided on the surface of the rear door 17, and L-shaped stabilizing strips 23 are plugged inside the two stabilizing frames 22. The staff first passes the wires that the total station body 3 needs to connect with the outside through the two arc-shaped sealing strips 21, and then rotates the rear door 17 around the hinge toward the direction of the protection box 1 until the rear door 17 is completely fitted into the opening of the protection box 1, and then the L-shaped connecting strip 18 is rotated and clamped into the corresponding connecting frame, and the rear door 17 is preliminarily fixed to make its position relatively stable and will not shake at will;

[0036] Next, push the L-shaped stabilizing bar 23 to drive the moving plate 20 to slide in the movable groove toward the inside of the protective box 1, so that the connecting holes on the moving plate 20 and the rear door 17 and the arc-shaped sealing strip 21 are realigned and tightly matched, thereby ensuring the sealing of the inside of the protective box 1 and preventing external impurities such as rainwater and dust from entering the inside of the protective box 1 through the gap at the rear door 17, affecting the normal use and performance of the total station body 3.

[0037] Reference Figure 7-8As shown, one end of the L-shaped stabilizing bar 23 is connected to the surface of the moving plate 20, and slots are provided on the surfaces of the stabilizing frame 22 and the L-shaped stabilizing bar 23, and a T-shaped limiting bar 24 is inserted into the slots. A top plate 25 is fixedly provided on the top of the protective box 1, and a plurality of guide grooves 26 are provided on the surface of the guide groove 26. A supporting leg 27 is fixedly provided on the bottom of the fixed tray 2, and the T-shaped limiting bar 24 is inserted into the slots on the surfaces of the stabilizing frame 22 and the L-shaped stabilizing bar 23, and the L-shaped stabilizing bar 23 is limited and fixed again to ensure that the rear door 17 is firmly closed, and the entire connecting mechanism is restored to the initial stable state, and the protective box 1 continues to play a good protective role for the total station body 3;

[0038] When it rains, the top plate 26 on the top of the protection box 1 can directly receive the rainwater falling from above. The multiple guide grooves 26 on its surface can guide the rainwater to flow away in a specific direction, avoiding the accumulation of rainwater on the top plate 26 to form water accumulation, thereby preventing the accumulated water from penetrating into the protection box 1 through the gaps on the top of the protection box 1. The support legs 27 at the bottom of the fixed tray 2 firmly support the entire protection box 1, so that the protection box 1 maintains a certain distance from the ground, avoiding the accumulated water, moisture and possible dirt on the ground from contacting the bottom of the protection box 1, and preventing moisture from penetrating into the protection box 1 through the bottom and affecting the total station body 3.

[0039] Working principle of the present invention:

[0040] The present invention is a total station for surveying and mapping geographic information for protection in rainy seasons. When the device is used, the staff first passes the wires that the total station body 3 needs to connect with the outside through the two arc-shaped sealing strips 21, and then rotates the rear door 17 around the hinge toward the direction of the protection box 1 until the rear door 17 is completely attached to the opening of the protection box 1, and then rotates the L-shaped connecting strip 18 to be connected to the corresponding connecting frame, and preliminarily fixes the rear door 17 so that its position is relatively stable and will not shake at will;

[0041] Next, push the L-shaped stabilizing bar 23 to drive the moving plate 20 to slide in the movable groove toward the inside of the protection box 1, so that the moving plate 20 and the connecting holes on the rear door 17 and the arc-shaped sealing strip 21 are realigned and closely matched, thereby ensuring the sealing of the inside of the protection box 1 and preventing external impurities such as rainwater and dust from entering the inside of the protection box 1 through the gap at the rear door 17, thereby affecting the normal use and performance of the total station body 3;

[0042] Finally, the T-shaped limit strip 24 is inserted into the slots on the surface of the stabilizing frame 22 and the L-shaped stabilizing strip 23, and the L-shaped stabilizing strip 23 is again limited and fixed to ensure that the rear door 17 is firmly closed, and the entire connection mechanism is restored to the initial stable state, and the protective box 1 continues to play a good protective role for the total station body 3;

[0043] When it starts to rain and the total station body 3 needs to be protected from rain, the operator starts the small stepper motor 6 in the heat dissipation box 5. A heat conducting plate is embedded in the bottom of the heat dissipation box 5. The heat conducting plate absorbs the heat generated by the small stepper motor 6 inside the heat dissipation box 5 when it is working, and conducts it outward to ensure normal heat dissipation of the small stepper motor 6. The small stepper motor 6 drives the winding rod 7 fixed at its output end to rotate clockwise. Since one end of the rainproof cloth 8 is firmly fixed to the surface of the winding rod 7, as the winding rod 7 rotates clockwise, the rainproof cloth 8 is gradually released from the winding rod 7 and unfolded. In this process, the rainproof cloth 8 slides downward along the through groove opened on the surface of the fixed frame 4. The through groove guides and constrains the movement direction of the rainproof cloth 8, ensuring that the rainproof cloth 8 can accurately unfold downward to cover one side of the protection box 1;

[0044] At the same time, the counterweight bar 9 fixed at one end of the rainproof cloth 8 slides smoothly downward along the slide groove on the surface of the protection box 1 by relying on the two T-shaped sliders 10 on one side under the action of its own gravity. The cooperation between the T-shaped slider 10 and the slide groove not only ensures the linearity of the sliding of the counterweight bar 9, but also prevents it from deviating left and right during the sliding process. When the counterweight bar 9 slides down to the position of the fixed plate 12 on one side of the protection box 1, the first magnetic strip 11 at the bottom of the counterweight bar 9 and the second magnetic strip 13 embedded in the surface of the fixed plate 12 attract each other and fit tightly together, so that the counterweight bar 9 is fixed at this position. At this point, the rainproof cloth 8 is fully unfolded, covering one side of the protection box 1, forming a rainproof barrier;

[0045] The transparent PVC film 15 fixedly arranged in the through hole opened on the surface of the rainproof cloth 8 can be used by the operator to view the display screen and operation buttons of the total station body 3 through it, so that the operator can understand the working status of the total station body 3 without putting away the rainproof cloth 8, and can prevent rain from directly contacting the total station body 3 without affecting the optical observation of the total station body 3. The sealing ring 16 on one side of the rainproof cloth 8 will fit tightly on the surface of the protection box 1, further enhancing the sealing between the rainproof cloth 8 and the protection box 1, and effectively preventing rain from penetrating into the protection box 1 from the gap between the two. When the rain stops or the rainproof cloth 8 is no longer needed for protection, the above steps are reversed to operate, and the entire rainproof cloth 8 is put away, waiting to be unfolded and used again when rain protection is needed next time;

[0046] When it rains, the top plate 26 on the top of the protection box 1 can directly receive the rainwater falling from above. The multiple guide grooves 26 on its surface can guide the rainwater to flow away in a specific direction, avoiding the accumulation of rainwater on the top plate 26 to form water accumulation, thereby preventing the accumulated water from penetrating into the protection box 1 through the gaps on the top of the protection box 1. The support legs 27 at the bottom of the fixed tray 2 firmly support the entire protection box 1, so that the protection box 1 maintains a certain distance from the ground, avoiding the accumulated water, moisture and possible dirt on the ground from contacting the bottom of the protection box 1, and preventing moisture from penetrating into the protection box 1 through the bottom and affecting the total station body 3.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
