[0002] Outdoor measurement devices generally refer to electronic devices used outdoors for data collection, processing and output of surveying and mapping work, including range finders, altimeters, compasses, levels and the like. In actual use, the outdoor measurement device is usually used in combination with a tripod, specifically the tripod is fixed to the ground, and the device is fixed to the support table at the top end of the tripod, and the outdoor measurement device is stabilized by the tripod.

[0003] When working in scenes such as construction sites, there are a large amount of dust in the environment, which can easily float and cover the surface of the measurement device, causing surface pollution and affecting the accuracy when starting measurement. Therefore, the operator at the outdoor measurement site usually wipes the dust on the surface of the measurement port with a cloth before starting the device.

[0004] The inventor found that the existing dust removal method is harsh, which not only requires the operator to carry a cloth, but also requires the cloth to be effectively stored (i.e., the surface does not have hard particles that can scratch the device), which is inconvenient.

The dust removal mechanism for outdoor measurement equipment provided by the present application comprises a support table 1, a mounting seat 2, a positioning plate 3 and a translation shaft 4.

[0055] The support table 1 adopts a table-like structure extending in the horizontal direction, and the outdoor measurement equipment is fixedly arranged at the center of the upper side of the support table 1, and the detection surface of the outdoor measurement equipment faces the horizontal direction.

[0056] The mounting seat 2 is detachably arranged on the upper side of the support table 1, and is located outside the outdoor measurement equipment.

[0057] The positioning plate 3 is hingedly connected to the mounting seat 2 in the horizontal direction, and has a locking structure 5 between the positioning plate 3 and the mounting seat 2; by swinging the positioning plate 3 relative to the mounting seat 2, and connecting the mounting plate 2 and the positioning plate 3 through the locking structure 5, the positioning plate 3 can be locked in a horizontal state or a vertical state; wherein, when the positioning plate 3 is in the horizontal state, the swinging end thereof is located on the side of the mounting seat 2 away from the outdoor measurement equipment, so as to avoid interfering with the normal use of the outdoor measurement equipment; when the positioning plate 3 is in the vertical state, the swinging end thereof is located on the upper side of the mounting seat 2, so as to ensure that the inner side of the positioning plate 3 shields the detection surface of the outdoor measurement equipment.

[0060] The sliding shaft 4 is drivingly connected with a rotating driving member 6 for driving the sliding shaft 4 to rotate.

[0061] In actual use, the rotating driving member 6 can drive the sliding shaft 4 to rotate; at this time, if the sponge block 41 abuts against the surface of the outdoor measuring equipment, the sponge block 41 can rotate relative to the outdoor measuring equipment to make the dust on the surface of the outdoor measuring equipment fall off.

[0062] In the embodiment, the support table 1 can fix the outdoor measuring equipment and ensure that the detection end of the outdoor measuring equipment faces the horizontal direction; based on this, the opening of the groove 31 can be arranged opposite to the detection end of the outdoor measuring equipment by manually controlling the positioning plate 3 to swing; at this time, the cover 32 is removed from the opening of the groove 31, and the sliding shaft 4 can move under the action of the elastic reset member 42 to make the sponge block 41 contact the detection end surface of the outdoor measuring equipment. When the sponge block 41 contacts the detection end surface of the outdoor measuring equipment, the sponge block 41 can be rotated by starting the rotating driving member 6, so that the dust on the surface of the outdoor measuring equipment falls off.

[0063] Before the sponge block 41 rotates, cleaning liquid can be injected into the sponge block 41 to ensure the dust removal effect. In addition, after the dust removal work on the surface of the outdoor measuring equipment is completed, the positioning plate 3 can be manually controlled to swing to avoid the detection end of the outdoor measuring equipment, so that the outdoor measuring equipment can be normally used.

[0064] Compared with the prior art, the dust removal mechanism for the outdoor measuring equipment can quickly remove the dust on the surface of the equipment, and does not interfere with the normal work of the outdoor measuring equipment, so as to ensure the accuracy of the outdoor measuring equipment during operation.

[0076] The insertion rod 53 is adapted to be inserted into the positioning hole 51 and the insertion hole 52 in communication to limit the swing of the swing arm 7 relative to the mounting seat 2.

[0077] One end of the insertion rod 53 is provided with a top disc 531 extending radially outward, and the other end is sleeved with an elastic ring 532; when the insertion rod 53 is inserted into the positioning hole 51 and the insertion hole 52 which are in communication with each other, the top disc 531 and the elastic ring 532 abut against the outside to limit the insertion rod 53 from separating from the combined structure of the mounting seat and the swing arm 7.
