Description

Technical Field

[0001] The present invention relates to the technical field of optical measurement, in particular to an L-shaped waterproof seeing meter. Background Art

[0002] Most seeing meters currently on the market are open-type designs, requiring an astronomical dome or flat push-roof for protection. The turntable is typically designed with two-dimensional vertical axes, rotating along two perpendicular axes to scan and track a flat or spherical surface. Many small two-dimensional turntables, whether equatorial or horizontal, require numerous counterweights to balance the load. Many popular science-grade two-dimensional turntables use stepper motors for their drive, calculating rotation distance based on the number of stepper motor pulses. This can lead to inaccurate pointing due to backlash and slippage. Turntables are typically driven by electric motors, and the electronic components in the motors and control systems are not waterproof. The turntable housing is primarily designed to prevent external contact or provide safety protection and is generally not waterproof. Many optical measurement systems utilize open trusses or simple optical telescopes. The front panel has two apertures spaced a certain distance apart: one is an unobstructed hole, and the other is a 1-2 degree dichroic wedge. This design allows the same star to pass through the dual apertures, resulting in two separate images on the back-end measurement camera. The camera captures a series of images using high-frequency, short exposures. The change in distance between two celestial bodies is then numerically calculated to determine atmospheric stability, or the seeing value. The focuser and camera components are exposed to the elements. Before severe weather like precipitation and sandstorms occurs, the dome must be closed manually or automatically to protect the turntable and optical system from the effects of wind, sand, and precipitation.

[0003] The two-dimensional turntables used in common seeing instruments are mostly horizontal or equatorial, designed to carry no more than 50 kg. Whether horizontal or equatorial, the turntable is shaped like a "T." When a telescope (payload) is mounted on one side, a suitable counterweight must be mounted on the other side for balance. This results in a relatively high load-bearing capacity, but the effective load-bearing capacity is limited. Most two-dimensional turntables lack a disc or a relative disc, requiring manual change after each power outage. Furthermore, many turntable drive components are exposed, making them less adaptable to inclement weather and environmental conditions. Even a small amount of precipitation can damage the turntable. The optical measurement system's front panel has a wedge-shaped aperture to protect against minor precipitation, but the aperture for the primary optical path is unprotected. This allows precipitation and dust to enter the optical system directly through this aperture, affecting cleanliness and imaging. Excessive precipitation can short-circuit and damage electronic components such as the focus and camera. The existing design mainly protects the equipment by closing the external dome. The seeing meter itself does not have a special waterproof design, so the whole device cannot withstand rainy and snowy weather and environment.

[0004] Based on the above technical problems, technical personnel in this field urgently need to develop an L-shaped waterproof seeing meter with a simple and compact structure, certain waterproof capabilities, the ability to adapt to relatively severe weather and environment, and suitable for remote control and automated execution of tasks.

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] See also Figures 1 to 3 As shown;

[0046] An L-shaped waterproof seeing meter of the present invention comprises:

[0047] Bottom support mechanism 1;

[0048] and a horizontal bearing assembly 2 located at the upper end of the bottom support mechanism 1. A first driving mechanism 3 is provided at one end of the bottom support mechanism 1, and the horizontal bearing assembly 2 is connected to the first driving mechanism 3;

[0049] An L-shaped support mechanism 4 mounted on the upper end of the horizontal bearing assembly 2 includes a vertical bearing assembly 401 and a second drive mechanism 403. A night light sensing window 402 is formed on the top of the L-shaped support mechanism 4 to automatically measure changes in sky light, facilitating remote automatic observation and task execution.

[0050] The meter also includes:

[0051] The optical measurement system 5 is connected to the vertical bearing assembly 401 through an adapter, specifically a saddle-shaped adapter plate. The vertical bearing and the horizontal bearing are connected to the L-shaped facade through the contact surfaces of the inner and outer rings of the bearings, and the optical measurement system 5 is configured as a closed structure.

[0052] In this embodiment, industrial-grade steel-plastic sealed bearings are used. The axial and radial load-bearing capacities of the two bearings are both greater than 300kg. Considering the convenience of transportation and lightweight design, the weight of each module is relatively small, and the total load-bearing capacity of the support and drive parts can reach 80-100kg.

[0053] The upper part of the turntable adopts a unilateral fixing mode. In theory, as long as the weight does not exceed the load-bearing design of the turntable, it can be loaded with telescopes of any size.

[0054] The electrical control and driving parts of the L-shaped support mechanism 4 are protected in the sealed cavity, so the entire L-shaped support mechanism 4 has a certain waterproof capability.

[0055] As a further introduction to this embodiment, the bottom support mechanism 1 includes a horizontally arranged base 101; and

[0056] A support cylinder 102 is vertically arranged at the upper end of the base 101, and the horizontal bearing assembly 2 is located at the upper end of the support cylinder 102;

[0057] The first protective shell 103 is used to cover the first driving mechanism 3 , and a sealing strip is installed on the inner edge of the first protective shell 103 .

[0058] As a further introduction to this embodiment, the horizontal bearing assembly 2 includes a horizontal bearing code disc and an encoder;

[0059] The vertical bearing assembly 401 includes a vertical bearing code disc and an encoder.

[0060] The moving parts of the turntable reserve enough space for the code disc and encoder to obtain accurate position and speed information.

[0061] As a further introduction to this embodiment, the first driving mechanism 3 includes a first motor 301 provided on one side of the support cylinder 102; and

[0062] The horizontal reducer 302 is connected to the first motor 301 , and the horizontal bearing assembly 2 is connected to the horizontal reducer 302 .

[0066] An installation and maintenance hole 405 is provided in the middle of the horizontal portion of the L-shaped support mechanism 4 .

[0067] As a further introduction to this embodiment, the optical measurement system 5 includes a telescope barrel 501 connected to the vertical bearing assembly 401; and

[0068] A waterproof structure 502 connected to the front end of the telescope barrel 501;

[0069] A measuring device 503 is provided at the rear end of the telescope barrel 501 .

[0070] As a further introduction to this embodiment, the waterproof structure 502 includes a mask 5021 connected to the front end of the telescope barrel 501;

[0071] The mask 5021 is formed with an original light path 5022 and a wedge light path 5023 .

[0072] As a preferred technical solution of this embodiment, quartz optical glass is installed on both the original light path 5022 and the wedge light path 5023, a waterproof rubber ring is installed at the connection between the wedge light path 5023 and the mask 5021, and the optical path difference between the original light path 5022 and the wedge light path 5023 is consistent.

[0073] The front panel 5021 is made of aluminum alloy, which is easy to process and has excellent mechanical strength and thermal conductivity;

[0074] The connection between the mask 5021 and the telescope tube 501 is sealed with a waterproof rubber ring and a buckle with certain weather resistance, ensuring that the entire front end part can be reliably connected to the optical telescope tube without loosening or vibration in snowfall, precipitation and strong winds.

[0075] At the rear end of the two optical holes, a polyimide heating film is applied inside. When the humidity is high and the temperature is low, frost may appear on the surface of the optical glass. At this time, proper heating can quickly remove the frost without damaging the optical components.

[0076] The Kajiao telescope adopting the closed lens barrel design is equipped with the waterproof mask provided by this embodiment, so that the entire system has a certain waterproof and dustproof performance.

[0077] The focusing and camera of the Kajiao telescope are installed at the rear end of the telescope. A circular lightweight (plastic or carbon fiber) cover is set to cover the entire rear end to provide dust and waterproof protection.

[0078] The L-shaped waterproof seeing meter designed by the present invention can be installed and debugged through the installation and maintenance hole 405. First, the horizontal axis base and the L-shaped vertical support can be connected together through this hole. Then, the power line, control line, signal line and other cables inside the L-shaped support mechanism 4 run straight down and enter the lowermost support tube 102 through the middle hole of the horizontal bearing. Finally, a cover with a sealing strip is installed in the installation and maintenance hole 405, and sealing strips are installed on the inner edges of the vertical axis and horizontal axis protective shells. After the cover and protective shell are installed, the electrical parts are protected in a relatively sealed cavity, and the whole system has a certain degree of waterproofness. The front end of the closed optical measurement system 5 has a waterproof light transmission system and a mask, the middle section has a closed optical lens barrel, and the rear end imaging and measurement equipment are protected in a waterproof cover, which can make the entire system have a certain degree of waterproofness in rainy and snowy weather and environment.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
