DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a surveying and mapping auxiliary bracket includes a support leg 1, a mounting plate 2 is fixed to the top of the support leg 1, a surveying and mapping instrument body 3 is fixed to the upper surface of the mounting plate 2, and an auxiliary mechanism 4 is provided on the mounting plate 2 to facilitate the surveying and mapping of the surveying and mapping instrument body 3;

[0022] The auxiliary mechanism 4 includes a dustproof component 41 for preventing dust from forming on the surveying and mapping instrument body 3 after the surveying and mapping instrument body 3 is stored, and a dustproof component 42 for preventing dust from forming on the surveying and mapping instrument body 3 when the surveying and mapping instrument body 3 is working. The dustproof component 42 is disposed on the dustproof component 41.

[0023] The dustproof component 41 includes four columns 411 which are vertically fixed on the mounting plate 2 and distributed in a rectangular shape. The top ends of the four columns 411 are fixed with a same horizontal top plate 412. A bellows 413 is fixed to the upper surface of the mounting plate 2. An annular metal strip 414 is fixed to the top end of the bellows 413. A magnet ring 415 facing the direction of the annular metal strip 414 is fixed to the lower surface of the top plate 412.

[0024] It should be noted that when the surveying instrument body 3 is not in use, the bellows 413 is designed to be deformable and lifted up so that the annular metal strip 414 and the magnet ring 415 are attracted to each other, so that the entire surveying instrument body 3 is wrapped by the bellows 413 to effectively protect the surveying instrument body 3.

[0025] The four columns 411 are all located in the bellows 413, and the height of the columns 411 is greater than the height of the surveying instrument body 3.

[0026] It should be noted that such a design allows the dustproof assembly 41 to fully cover and protect the surveying instrument when the surveying instrument body 3 is not in operation, thereby preventing dust from accumulating on the surveying instrument and affecting its performance and measurement accuracy. At the same time, due to the height design of the column 411, the dustproof assembly 41 can also adapt to surveying instrument bodies 3 of different heights, thereby increasing its applicability and flexibility.

[0027] The center of the magnet ring 415 and the center of the annular metal strip 414 are located on the same vertical line, and the outer diameters of the two are equal.

[0028] Among them, the dust-blocking component 42 includes a fan 421 fixed on the upper surface of the top plate 412, an exhaust pipe 422 is fixed to the air inlet end of the fan 421, a dust-proof net 423 is fixed inside the exhaust pipe 422, and an annular tube 424 is fixed to the lower surface of the top plate 412, and the annular tube 424 is connected to the air outlet end of the fan 421.

[0029] It should be noted that when the surveying instrument body 3 is working, the fan 421 inhales air through the exhaust pipe 422 and the dustproof net 423, and then outputs it through the annular pipe 424 and the air outlet head 425, forming a wind wall around the surveying instrument body 3 to block dust, and the dustproof net 423 is used to block the dust in the air.

[0030] The lower surface of the annular tube 424 is connected to a plurality of gas outlets 425 distributed in an annular shape, and the inner diameter of the annular tube 424 is respectively larger than the length and width of the surveying and mapping instrument body 3 .

[0031] The upper surface of the top plate 412 is partially missing to form a circular opening, one end of the annular tube 424 passes through the opening and a sealing ring is fixed at the connection with the opening.

[0032] It should be noted that when the air outlet head 425 is venting air, the air circulation speed at the surveying and mapping instrument body 3 can also be increased, and heat dissipation can be performed in summer.

[0033] The working principle of the above embodiment is as follows: when the surveying instrument body 3 is working, the fan 421 inhales air through the exhaust pipe 422 and the dustproof net 423, and then outputs it through the annular tube 424 and the air outlet head 425, forming a wind wall around the surveying instrument body 3 to block dust, and the dustproof net 423 is used to block the dust in the air. When the air outlet head 425 discharges air, the air circulation speed at the surveying instrument body 3 can also be increased, and heat dissipation can be performed in summer. When the surveying instrument body 3 is not in use, the variability design of the bellows 413 is used to lift it up so that the annular metal strip 414 and the magnet ring 415 are adsorbed on each other, so that the entire surveying instrument body 3 is wrapped by the bellows 413 to effectively protect the surveying instrument body 3.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
