Abstract
Description
Technical Field
[0001] This utility model relates to surveying equipment, specifically to a prism protection device based on a fixed observation pier. Background Technology
[0002] In the construction of large-scale projects such as buildings, bridges, water conservancy and hydropower, and high-speed railways, it is essential to construct sturdy control point markers and mount prisms on them to ensure accurate coordinate positioning of the structures. Typically, these control point markers are built in stable locations far from the construction site, usually outdoors. This makes the prisms susceptible to external dust and theft, increasing the cost and difficulty of surveying and reducing efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is that, in view of the lack of dustproof and anti-theft protection measures for existing surveying user external prisms, this utility model provides a prism protection device based on a fixed observation pier that can effectively improve the efficiency of surveying work, and is simple, practical and easy to operate.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A prism protection device based on a fixed observation pier includes an observation pier and a prism mounted on the observation pier, characterized by the following structural features:
[0006] The observation pier is also equipped with a lifting mechanism, which includes a lead screw installed vertically on the observation pier, a connector threaded to the lead screw, and a motor connected to the connector. A protective cover is fixedly connected to the connector. The motor is electrically connected to a controller for controlling the motor's movement. The motor drives the connector and the protective cover to rise or fall together along the lead screw, so that the prism is exposed or covered by the protective cover.
[0007] A further improvement to the above solution is that the controller is a wireless controller, and the wireless controller is equipped with a remote control.
[0008] A further improvement to the above solution is that a solar power source is installed on the protective cover, and the solar power source is electrically connected to the controller.
[0009] A further improvement to the above solution is that a reflective strip is provided on the protective cover.
[0010] A further improvement to the above solution is that a mark is set on the reflective strip.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1) This utility model has the characteristics of simple structure, easy installation and disassembly, convenient operation, economy and strong practicality, and can realize the dustproof, rainproof, anti-aging and anti-theft of prism.
[0013] 2) This utility model can remotely raise and lower the protective cover from a distance using a remote control, and can improve the visibility of the measuring marker through reflective strips, effectively reducing manpower and time input in the measurement work and improving the efficiency of the measurement work.

[0018] The present invention will be further described below with reference to specific preferred embodiments, but this does not limit the scope of protection of the present invention.
[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Please see Figure 1 An embodiment of the prism protection device based on a fixed observation pier of this utility model includes an observation pier 1 and a prism 2 installed on a forced centering base on the top of the observation pier 1.
