Description

Technical Field

[0001] The present application relates to the field of engineering surveying technology, and in particular to a total station protection device. Background Art

[0002] Total station automated deformation monitoring has been widely used in deformation monitoring projects such as railways, subways, and landslides. However, due to the high cost of total stations, in related technologies, total stations are often protected by building total station protection rooms outdoors, which can not only provide all-weather physical protection for the total station, but also prevent the total station from being stolen.

[0003] However, the total station protection room is difficult to build and cannot be reused. The total station installed inside is easily affected by falling dust, rain and fog, resulting in dust accumulation and adsorption of iron filings, which affects the measurement effect. Summary of the invention

[0004] In order to reduce the impact of the environment on the total station, the present application provides a total station protection device.

[0005] The present application provides a total station protection device, which adopts the following technical solution:

[0006] A total station protection device comprises a base, an inner cylinder, an outer cylinder, a transmission mechanism, a driving mechanism and a photovoltaic power supply mechanism, wherein a placement area for installing the total station is provided on the base, the inner cylinder and the outer cylinder are coaxially arranged in the placement area, a first rack is provided on the outer wall of the inner cylinder, a second rack is provided on the inner wall of the outer cylinder, the first rack and the second rack are arranged oppositely and paired into a plurality of groups, the first rack and the second rack are both arranged along the axial direction of the inner cylinder, the transmission mechanism comprises a support frame fixedly mounted on the base and located between the inner cylinder and the outer cylinder, and an active bevel gear and a driven circular gear rotatably connected to the support frame, tooth surfaces on opposite sides of the active bevel gear are respectively meshed with the first rack and the second rack, and tooth surfaces on opposite sides of the driven circular gear are also respectively meshed with the first rack and the second rack, the driving mechanism is used to drive the active bevel gear to rotate, the photovoltaic power supply mechanism is used to supply power to the driving mechanism, and the side walls of the inner cylinder and the outer cylinder are axially provided with observation windows staggered from each other.

[0007] By adopting the above technical solution, the total station is fixed on the placement area of ​​the base when in use, and the inner and outer cylinder covers are arranged outside the total station, providing double protection for the total station. The photovoltaic energy supply mechanism absorbs sunlight and energizes the driving mechanism, and the driving mechanism drives the active bevel gear to rotate. Since the tooth surfaces on the opposite sides of the active bevel gear are respectively engaged with the first rack and the second rack, the movement directions of the inner cylinder and the outer cylinder are opposite. The driven circular gear plays an auxiliary role in guiding and supporting the movement of the inner cylinder and the outer cylinder.

[0008] The driving mechanism can drive the inner cylinder and the outer cylinder to make the observation windows staggered or overlapped, so that the lens of the total station is exposed to the outside or blocked. This plays a protective role for the total station. There are also solutions in the related art to use a glass protective cover to protect the total station, but the glass protective cover is easy to be damaged on the one hand, and on the other hand, the glass has a certain degree of refraction effect on the measurement results, and it is difficult to clean.

[0009] In order to ensure that the outer cylinder and the inner cylinder are not violently dismantled, the inner cylinder and the outer cylinder are preferably metal cylinders with sufficient thickness and high weight. However, due to the small area of ​​the outer cylinder, the photovoltaic energy supply mechanism has a small power generation capacity and the battery has poor power storage capacity, and the power supply power is low. Compared with directly lifting and controlling a single protective cylinder, the weight of the two cylinders acts on the opposite sides of the gear respectively, so the driving force that the driving mechanism needs to apply to the active bevel gear does not need to be too large, thereby meeting the supply conditions of the photovoltaic energy supply mechanism.

[0010] Optionally, an inner ring groove and an outer ring groove surrounding the inner ring outside are provided on the base, the outer tube is embedded in the outer ring groove and slidably connected to the outer ring groove, and the inner tube is embedded in the inner ring groove and slidably connected to the inner ring groove.

[0011] By adopting the above technical solution, since the inner tube and the outer tube move up and down, the setting of the outer ring groove and the inner ring groove is conducive to hiding the lower edges of the inner and outer tubes in the base, thereby preventing the inner tube and the outer tube from being pried open by force and being damaged.

[0012] Optionally, a support wall is provided between the inner annular groove and the outer annular groove, and the support wall is fixedly connected to the support frame.

[0013] By adopting the above technical solution, on the one hand, the support wall is used to install and fix the support frame, and on the other hand, the support wall is used to separate the inner ring groove and the outer ring groove, which can prevent external rainwater from overflowing into the placement area.

[0014] Optionally, the support frame includes a support column and a support ring, the support column is arranged along the axial direction of the inner cylinder, the support ring is arranged in the gap between the inner cylinder and the outer cylinder and coaxially with the inner cylinder, and both ends of the support column are fixedly connected to the support ring and the base respectively.

[0015] By adopting the above technical solution, the support column supports the support ring, and the weight of the inner cylinder and the outer cylinder is transferred to the support wall through the support ring and the support column.

[0016] Optionally, the driving bevel gear and the driven circular gear are both sleeved on a support ring and rotatably connected to the support ring.

[0017] By adopting the above technical solution, the inner cylinder and the outer cylinder can freely move relative to each other based on the driving bevel gear and the driven circular gear.

[0018] Optionally, the photovoltaic energy supply mechanism includes a photovoltaic panel arranged on the surface of the outer cylinder and a storage battery arranged in the base, and the photovoltaic panel is electrically connected to the storage battery.

[0019] Optionally, the driving mechanism includes a reduction motor and a driving bevel gear, the reduction motor is installed in the base, the output shaft of the reduction motor is arranged along the axial direction of the inner cylinder and is fixedly connected to the driving bevel gear, and the driving bevel gear is meshed with the active bevel gear.

[0020] By adopting the above technical solution, the reduction motor drives the driving bevel gear to rotate in a timely manner, and the driving bevel gear and the active bevel gear cooperate with each other to convert the rotation around the output shaft into the rotation around the support ring.

[0030] The present application embodiment discloses a total station protection device. Figure 1 and Figure 2 The total station protection device includes a base 1, and also includes an inner cylinder 2, an outer cylinder 3, a transmission mechanism 4, a driving mechanism 5 and a photovoltaic power supply mechanism installed on the base 1. The base 1 is used to carry the total station, the inner cylinder 2 and the outer cylinder 3 are used to cover the outside of the total station to protect the total station, the photovoltaic power supply mechanism is used to operate the driving mechanism 5, and the driving mechanism 5 controls the inner cylinder 2 and the outer cylinder 3 to move relative to each other through the transmission mechanism 4. Observation windows 6 are provided on the inner cylinder 2 and the outer cylinder 3. During the relative movement of the inner cylinder 2 and the outer cylinder 3, the observation windows 6 of the inner cylinder 2 and the observation windows 6 of the outer cylinder 3 are aligned or staggered with each other, so that the lens of the total station is exposed or covered.

[0031] Reference Figure 3The base 1 is used to be installed on the ground. In different embodiments, the base 1 can have different shapes or be made of different materials, as long as a flat placement area 11 can be formed on the top for placing the total station. Preferably, in order to improve the anti-theft performance, the base 1 can be made of a hollow metal box. In this embodiment, the base 1 is a cylindrical box, the interior of which is used to accommodate the fixed drive mechanism 5. In order to facilitate maintenance, an openable and closable maintenance door 12 is set on the side of the base 1.

[0032] The driving mechanism 5 includes a reduction motor 51 and a driving bevel gear 52. The reduction motor 51 is fixedly installed in the base 1, and the output shaft 53 passes through the placement area 11 and is perpendicular to the plane of the placement area 11. The driving bevel gear 52 is fixedly arranged at the end of the output shaft 53 of the reduction motor 51 and is coaxially arranged with the output shaft 53.

[0033] The placement area 11 is provided with an inner ring groove 13 and an outer ring groove 14, both of which are circular ring grooves and are arranged around the same axis. A support wall 15 is provided between the inner ring groove 13 and the outer ring groove 14, the outer side wall of the support wall 15 is the side wall of the outer ring groove 14, the inner side wall of the support wall 15 is the side wall of the inner ring groove 13, and the output shaft 53 of the reduction motor 51 passes through the support wall 15 to pass through the placement area 11.

[0034] Reference Figure 2 , the inner cylinder 2 is sleeved inside the outer cylinder 3, and the inner cylinder 2 and the outer cylinder 3 are coaxially arranged in the placement area 11, and the openings are all facing the base 1. The opening edge of the outer cylinder 3 is embedded in the outer ring groove 14 and slidably connected to the outer ring groove 14, and the opening edge of the inner cylinder 2 is embedded in the inner ring groove 13 and slidably connected to the inner ring groove 13. As a result, the outer ring groove 14 can limit the outer cylinder 3 to move in the direction toward or away from the base 1, and the inner ring groove 13 can limit the inner cylinder 2 to move in the direction toward or away from the base 1. In order to match the shapes of the inner ring groove 13 and the outer ring groove 14, the inner cylinder 2 and the outer cylinder 3 are both cylinders. In different embodiments, the inner cylinder 2 and the outer cylinder 3 can be made of different materials, such as glass, plastic, metal, etc. Plastic has the advantages of high strength and light weight, but is prone to aging under long-term sunlight. Glass has the problems of being fragile and low safety, while metal has the problem of high weight. In this solution, metal cylinders are preferably used as the inner cylinder 2 and the outer cylinder 3.

[0035] Reference Figure 2 and Figure 4, the side walls of the inner tube 2 and the outer tube 3 are both provided with observation windows 6, and the observation windows 6 are used for the lens of the total station to be exposed or shielded. A plurality of first racks 21 are provided on the outer wall of the inner tube 2, and a plurality of second racks 31 are provided on the inner wall of the outer tube 3. The number of the first racks 21 and the second racks 31 is equal and they are paired into a plurality of groups, and each group of the first racks 21 and the second racks 31 are arranged opposite to each other. Specifically, the first racks 21 and the second racks 31 are both arranged away from the base 1, that is, arranged along the axial direction of the inner tube 2.

[0036] In order to overcome the problem that the inner cylinder 2 or the outer cylinder 3 is too heavy and difficult to lift, the driving mechanism 5 drives the inner cylinder 2 and the outer cylinder 3 through the transmission mechanism 4. The transmission mechanism 4 includes a support frame 41 fixedly mounted on the support wall 15 and located between the inner cylinder 2 and the outer cylinder 3, and a driving bevel gear 42 and a driven circular gear 43 rotatably connected to the support frame 41. The support frame 41 includes a support column 411 and a support ring 412. The support column 411 is arranged along the axial direction of the inner cylinder 2. In this embodiment, the number of the support columns 411 is three and is evenly distributed along the support wall 15. The support column 411 can be installed on the support wall 15 by welding or bolting, etc., as long as the method that can make the support column 411 fixedly connected to the support wall 15 is acceptable. The support ring 412 is arranged in the gap between the inner cylinder 2 and the outer cylinder 3 and is coaxially arranged with the inner cylinder 2. The two ends of the support column 411 are respectively fixedly connected to the support ring 412 and the base 1.

[0037] The driving bevel gear 42 and the driven circular gear 43 are both sleeved on the support ring 412 and are rotatably connected with the support ring 412. It should be noted that the support ring 412 is not a perfect circular ring. The part of the support ring 412 on which the driving bevel gear 42 and the driven circular gear 43 are sleeved is a straight part, so that the driving bevel gear 42 and the driven circular gear 43 can rotate smoothly. In this embodiment, the number of the driving bevel gear 42 is one, and the number of the driven circular gear 43 is two. The driving bevel gear 42 and the driven circular gear 43 are evenly distributed along the support ring 412 and correspond to the rack set. Specifically, the driving bevel gear 42 corresponds to the position of the driving spur gear and meshes with each other. When the reduction motor 51 drives the driving bevel gear 52 to rotate at a fixed time, the driving bevel gear 52 and the driving bevel gear 42 cooperate with each other to convert the rotation around the output shaft 53 into the rotation around the support ring 412.

[0038] The tooth surfaces on opposite sides of the active bevel gear 42 are respectively meshed with the first rack 21 and the second rack 31, and the tooth surfaces on opposite sides of the driven circular gear 43 are also respectively meshed with the first rack 21 and the second rack 31. Since the tooth surfaces on opposite sides of the active bevel gear 42 are respectively meshed with the first rack 21 and the second rack 31, both sides of the active bevel gear 42 are subjected to a downward pulling force, that is, the gravity of the inner cylinder 2 and the outer cylinder 3 are transmitted to the support wall 15 through the support ring 412 and the support column 411, and when the active bevel gear 42 rotates, it only needs to overcome the difference in gravity and friction between the inner cylinder 2 and the outer cylinder 3.

[0039] The photovoltaic energy supply mechanism includes a photovoltaic panel arranged on the surface of the outer cylinder 3 and a storage battery (not shown in the figure) arranged in the base 1. The photovoltaic panel is electrically connected to the storage battery, and the storage battery is electrically connected to the reduction motor 51 for power supply, and is also electrically connected to the total station for power supply. During the day, sunlight shines on the photovoltaic panel, and the photovoltaic panel charges the storage battery. Through the pre-set program setting, the storage battery supplies power to the reduction motor 51 and the total station at the set time, and the reduction motor 51 drives the driving bevel gear 52 to rotate. The driving bevel gear 52 is meshed with the active bevel gear 42, and the inner cylinder 2 and the outer cylinder 3 move relative to each other synchronously. The observation window 6 of the inner cylinder 2 and the observation window 6 of the outer cylinder 3 are close to each other and aligned with the lens of the total station, and the total station starts to work. After the set time, the driving motor drives the observation window 6 to stagger again, and the total station is shut down and powered off.

[0040] 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.
