[0002] Surveying and mapping instruments, to put it simply, are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output. They are various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction.

[0003] Surveying instruments often contain metal parts. These parts will expand and contract when the temperature changes, causing the size of the instrument to change. This change will directly affect the accuracy of the surveying instrument, especially when performing high-precision measurements. Temperature changes may also affect the stability and accuracy of the internal mechanical structure of the surveying instrument. For example, the clearance and friction of components such as gears and bearings will change with temperature, thereby affecting the measurement performance of the instrument. Therefore, a structure is needed to reduce the impact of temperature changes on the surveying instrument.

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A protective device for a surveying instrument, such as Figure 1-Figure 2As shown, it includes a surveying and mapping instrument 1 and a support base 2. The surveying and mapping instrument 1 is detachably connected to the support base 2. The support base 2 is usually set as a tripod. The tripod has higher stability and can better adapt to different ground surfaces. The connection between the surveying and mapping instrument 1 and the support base 2 is detachably connected with a protection component through a clamp 4. One end of the clamp 4 is connected together and the other end is adjusted by a bolt. It is more convenient to place it on the surveying and mapping instrument 1 and remove it from the surveying and mapping instrument 1, which improves the practicality of the protection device. The protection component includes a wrapping part, a shielding part, and a plurality of air pumps 3 connecting the wrapping part and the shielding part. The wrapping part and the shielding part are used alternately. The wrapping part and the shielding part are both set as deformable air bags. The wrapping part and the shielding part are filled with inert gas. The distribution of the inert gas The activity of the sub-part is slow, so the inert gas transfers heat more slowly. When the wrapping part is wrapped around the outside of the surveying and mapping instrument 1, the inert gas in the wrapping part blocks the heat change. When the surveying and mapping instrument 1 is suddenly placed in a higher temperature or lower temperature environment, there can be a buffer time, reducing the impact of temperature changes on the accuracy of the surveying and mapping instrument 1. When the surveying and mapping instrument 1 is placed outdoors, the inert gas in the wrapping part is transferred to the shielding part under the action of the air pump 3. After the shielding part is opened, it blocks the top of the surveying and mapping instrument 1, and can also block sunlight, reducing the impact of sunlight on surveying and mapping data. If it is placed in an indoor environment such as a well, it can be removed from the surveying and mapping instrument 1 after the surveying and mapping instrument 1 adapts to the ambient temperature, which is convenient for the normal use of the surveying and mapping instrument 1.

[0020] like Figure 2-Figure 6As shown, a support plate 5 is fixedly connected to the side of the clamp 4 away from the opening. When the clamp 4 is fixed on the support plate 5, the support plate 5 is arranged on one side of the surveying and mapping instrument 1 to avoid affecting the normal observation of the surveying and mapping instrument 1 due to the setting of the protection component. One end of the support plate 5 is fixedly connected to two symmetrically arranged storage boxes 6. The storage box 6 is arranged on the side close to the clamp 4. The wrapping part includes two protection airbags 7 with C-shaped cross-sections. One side of the protection airbag 7 is fixedly connected to the storage box 6. The two protection airbags 7 are independent of each other. Inert gas is filled in the protection airbag 7. One side wall of the storage box 6 is arranged as an opening. A slide rail 8 is slidably connected in the storage box 6. The bottom angle of one end of the protection airbag 7 is fixedly connected to the slide rail 8. One end of the protection airbag 7 close to the ground is fixed in the storage box 6 and the other end is fixed on the slide rail 8. After the slide rail 8 is unfolded, the width of the bottom surface of the protection airbag 7 is equal to the sum of the lengths of the slide rail 8 and the storage box 6. The slide rail 8 expands the extension of the protection airbag 7. Open range, ensure that the unfolded protection airbag 7 can be stably wrapped on the outside of the surveying and mapping instrument 1, a magnet sheet 1 is bonded to the side wall of the slide rail 8, and a magnetic sheet 2 that attracts the magnet sheet 1 is bonded to the inner wall of the storage box 6. When the slide rail 8 slides out of the storage box 6 to the limit state, the magnet sheet 1 and the magnet sheet 2 are magnetically fixed, so that the slide rail 8 can be relatively stably fixed in this state. The slide rail 8 supports the protection airbag 7 in a relatively stable state to prevent the protection airbag 7 filled with gas from swaying left and right after the wind blows, resulting in a reduction in the protection effect. At the same time, after the protection airbags 7 on both sides are unfolded, the side of the protection airbags 7 close to each other is bonded and fixed with a Velcro strip. The protection airbags 7 can be bonded and fixed together after they are close to each other to reduce the shaking of the protection airbag 7 and the flow of external gas along the gap between the two protection airbags 7. The Velcro strip is selected because its texture is softer than that of magnets, and the protection airbag 7 is easier to fold and store when stored.

[0021] like Figure 3-Figure 8As shown, a storage box 9 is fixedly connected to the top surface of the support plate 5, and the storage box 9 is used to store the shielding part. The shielding part includes a column airbag 10 and a sunshade airbag 11. The column airbag 10 and the sunshade airbag 11 are combined to form an umbrella shape that is biased to one side. The sunshade airbag 11 is fixedly connected to one end of the column airbag 10, and the sunshade airbag 11 is connected to the column airbag 10. The other end of the column airbag 10 is fixedly connected to the inner bottom surface of the storage box 9. The projection area of ​​the sunshade airbag 11 after unfolding is larger than the projection area of ​​the surveying and mapping instrument 1. When the surveying and mapping instrument 1 is moved out of the warehouse for use, the inert gas in the protective airbag 7 is transferred to the column airbag 10 and the sunshade airbag 11 through the air pump 3. After the gas in the protective airbag 7 is transferred, it is pulled and stored in the storage box 6. A telescopic rod 12 is fixedly connected to the inner wall of the bag 10. The minimum length of the telescopic rod 12 is less than the height of the storage box 9, and the maximum length is equal to the height of the column airbag 10. The two ends of the telescopic rod 12 are fixedly connected to the two ends of the column airbag 10 respectively. After the column airbag 10 is filled, the telescopic rod 12 will gradually extend under the pulling of the column airbag 10. Deformation protrusions and matching grooves are arranged between adjacent sections of the telescopic rod 12. The telescopic rod 12 is snap-fitted and fixed after it is fully unfolded. The telescopic rod 12 strengthens the hardness of the column airbag 10. The diameter of the column airbag 10 itself is small and it is easy to shake when blown by the wind. The addition of the telescopic rod 12 enables the column airbag 10 to better resist wind and improve the stability of the column airbag 10 and the sunshade airbag 11.

[0022] like Figure 3-Figure 8 As shown, two fixing frames 13 are fixedly connected to the side walls of the support plate 5, and several air pumps 3 are fixedly connected to the fixing frames 13 respectively. The air inlet pipe and the air outlet pipe of the air pump 3 are respectively connected to the protective airbag 7 and the columnar airbag 10. After the air pump 3 is turned on, the gas transmission can be realized, and there is no need for manual exhaust to improve the use efficiency of the protection component. The wrapping part and the shielding part are set to double-net double-sided sandwich PVC fabric. The double-net double-sided sandwich PVC fabric is commonly used in children's inflatable castles. It has good sealing performance and is not easy to leak after filling with gas. The inert gas is set to argon. The density of argon is 1.4 times that of air and it is very inactive. Argon has low cost and is suitable for use in protection devices, and can also ensure the effect of slowing down heat transfer efficiency.

[0023] like Figure 3-Figure 8As shown, a servo reciprocating dual-axis motor 14 is fixedly connected to the support plate 5, and the two rotors of the servo reciprocating dual-axis motor 14 rotate in opposite directions. One end of the rotor of the servo reciprocating dual-axis motor 14 extends into the storage box 9, and a pull rope 15 is fixedly connected to the rotor extending into the storage box 9. The other end of the pull rope 15 penetrates from the column airbag 10 and is fixedly connected to the side of the sunshade airbag 11 away from the column airbag 10. The other end of the rotor of the servo reciprocating dual-axis motor 14 is fixedly connected to a pull rope 2 16, and the other end of the pull rope 2 16 passes through the storage box 6 and is fixedly connected to the other side of the protection airbag 7. The servo reciprocating dual-axis motor 14 and the air pump 3 are controlled by the same control system. The servo reciprocating dual-axis motor 14 and the air pump 3 are started and stopped at the same time, and the control system controls them at the same time. After the air pump 3 is started, the rotor of the servo reciprocating dual-axis motor 14 also rotates synchronously. When the gas in the wrapping part and the shielding part is completely discharged, the servo reciprocating dual-axis motor 14 can also pull the protective airbag 7 to be stored in the storage box 6 or the columnar airbag 10 and the sunshade airbag 11 to be stored in the storage box 9, thereby improving work efficiency. The pull rope 15 and the pull rope 2 16 both pull the farthest ends of the sunshade airbag 11 and the protective airbag 7 to ensure that they can be pulled stably for storage.

[0024] like Figure 4-Figure 8 As shown, the two rotors rotate in opposite directions. When one rotor rotates clockwise, the other rotor rotates counterclockwise. The rotor close to the storage box 9 rotates clockwise, and the rotor pulls a pulling rope 15 spirally wrapped around its outer peripheral wall. The pulling rope 15 pulls the farthest end of the sunshade airbag 11 to gradually fold and store it. The air in the sunshade airbag 11 and the column airbag 10 is discharged, and the telescopic rod 12 is pulled by the column airbag 10 to gradually shrink and fold. Since the length of the telescopic rod 12 after folding is less than the height of the storage box 9, it is ensured that the column airbag 10 and the sunshade airbag 11 can be stably stored in the storage box 9.

[0025] A method for using a protective device of a surveying instrument, such as Figure 1-Figure 8 As shown, when the surveying and mapping instrument 1 is in use, the column airbag 10 expands to support the sunshade airbag 11 to shield the surveying and mapping instrument 1. At this time, the inert gas is filled in the column airbag 10 and the sunshade airbag 11, and the protective airbag 7 is stored in the storage box 6. When the surveying and mapping instrument 1 needs to be stored, the control system drives the air pump 3 and the servo reciprocating dual-axis motor 14 to open, and the rotor of the servo reciprocating dual-axis motor 14 pulls the sunshade airbag 11 through the pull rope 15 and is stored in the storage box 9 and gradually releases the pull rope 2 16. The inert gas is filled in the protective airbag 7 and pushes the protective airbag 7 to expand and wrap around the surveying and mapping instrument 1, thereby protecting the surveying and mapping instrument 1. It can not only reduce the impact of temperature on the surveying and mapping instrument 1, but also protect the surveying and mapping instrument 1 from being easily damaged by impact.

[0026] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
