Description
TECHNICAL FIELD
[0001] The utility model relates to atmospheric visibility detection technical field, specifically relates to the visibility evaluation device based on atmospheric waveguide effect in the field. BACKGROUND
[0002] Atmospheric visibility refers to the maximum distance that a person with normal vision can identify the outline of a target object under certain conditions, and is usually used to describe the scattering and absorption ability of light by the atmosphere. It is an important indicator for measuring air quality and atmospheric transparency, and is widely used in aviation, navigation, traffic management, environmental monitoring and other fields. In traditional visibility evaluation, the scattering and absorption characteristics of the atmosphere are mainly measured to determine the visibility range.
[0003] However, the actual measurement results of visibility are often affected by atmospheric waveguide effect. Atmospheric waveguide effect refers to the change of refractive index in the atmosphere under certain special weather conditions (such as temperature inversion, excessive humidity or pressure change), which causes the bending or guiding of light propagation path, thereby affecting the scattering and propagation of light. The existence of this waveguide effect makes the traditional visibility evaluation method based on light scattering or absorption unable to accurately reflect the visibility in the atmosphere, especially in areas or weather conditions where atmospheric waveguide phenomenon is obvious, the existing detection device has significant error.
[0004] Most of the atmospheric visibility detection devices on the market can only evaluate visibility based on the assumption of straight-line propagation of light, and lack the perception and adaptability of atmospheric waveguide effect. More importantly, most of the existing devices lack flexibility in design and cannot adjust the detection height and angle in real time according to the refractive index changes in different layers of the atmosphere. This makes the existing devices unable to effectively capture the real impact of waveguide effect on visibility. In addition, the structure of most existing atmospheric visibility detection devices is relatively complex, usually composed of detection part and support part, and the installation and disassembly process is not simple enough, which increases the operation time of the staff and reduces the work efficiency. UTILITY MODEL CONTENT
[0005] The technical problem to be solved by the utility model is to provide a visibility evaluation device based on atmospheric waveguide effect perception, which can perceive and reflect the influence of atmospheric waveguide effect on visibility, and has flexible adjustment capability, can adjust the detection height and angle in real time according to different weather conditions, to provide more accurate visibility evaluation results and improve the operation efficiency.
[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:
[0007] An improved atmospheric waveguide-sensing visibility assessment device includes a column, a mounting block, and a main unit. A cavity is provided inside the column. A driven pulley is located at the top of the cavity, and an active pulley is located at the bottom of the cavity. One end of the active pulley's shaft extends outside the column and is connected to a rocker wheel. A clearance groove communicating with the cavity is provided on the surface of the column. A movable block that can slide along the clearance groove is provided inside the cavity. A protrusion protruding from the clearance groove is provided on the movable block, and this protrusion is fixedly connected to the back of the mounting block. The top and bottom of the movable block are connected by a connecting rope fitted between the driven and active pulleys. A sliding groove is provided on the front of the mounting block. A fixing block that can be inserted into the sliding groove is provided on the back of the main unit. A side support rod is provided on each side of the main unit, and a detector is hingedly mounted on each side support rod.
[0008] Furthermore, an installation plate is installed at the bottom of the column.
[0009] Furthermore, a fastening bolt is screwed onto the rocker wheel, one end of which passes through the rocker wheel and can be screwed onto the outer wall of the column.
[0010] Furthermore, a scale strip adjacent to the clearance groove is installed on the outer wall of the column.
[0011] Furthermore, a slot that passes through the slide groove and a receiving groove that does not pass through the slide groove are provided on the mounting block. A locking rod that can pass through the fixing block is inserted into the slot, and a limiting rod is inserted into the receiving groove. One end of the limiting rod is connected to the inner wall of the receiving groove through a return spring, and the other end is connected to the locking rod through a toggle block protruding outside the mounting block. When the limiting rod is pulled out of the receiving groove, the return spring is stretched and generates a pulling force that pulls the limiting rod back into the receiving groove.
[0012] The beneficial effects of this utility model are:
[0013] The device disclosed in this utility model can drive the active pulley to rotate by rotating the rocker wheel, thereby causing the connecting rope sleeved between the driven pulley and the active pulley to move around the driven pulley and the active pulley. Since the moving block is connected to the connecting rope, the movement of the connecting rope can drive the moving block to slide up and down along the clearance groove. In turn, the mounting block fixedly connected to the moving block drives the main unit to move up and down, so as to flexibly adjust the height of the main unit and the detector, improve the detection flexibility of the device, and can adapt to different weather conditions and measurement needs in real time, thereby more accurately sensing the impact of atmospheric waveguide effect on visibility.
[0014] The detector is hinged to the side support rod, which can swing the detector to a specific angle and fix it. The side support rod is set on the main unit, and the height of the detector can be changed by adjusting the height of the main unit. This enables real-time adjustment of the detector's height and angle to adapt to the refractive index changes at different levels in the atmosphere, accurately sense the impact of atmospheric waveguide effects on the light propagation path, and provide accurate visibility assessment.
[0015] The device disclosed in this utility model is stably fixed to the ground by a mounting plate at the bottom of the column. A scale bar provides a numerical reference for operators when adjusting the height of the moving block. When the detection height does not need to be changed, the operator connects the fastening bolt on the rocker wheel to the threaded connection of the column to prevent the rocker wheel from rotating and causing a change in the detector position. When the detection height needs to be changed, the operator releases the fastening bolt from the threaded connection of the column, allowing the rocker wheel to be rotated.
[0016] The device disclosed in this utility model involves inserting a fixing block on the back of the main unit into a sliding groove on the front of the mounting block, followed by locking the fixing block with a locking rod to prevent it from moving within the groove. When the main unit needs to be removed, simply pulling the lever along with the locking rod releases the locking mechanism, allowing the fixing block to slide out of the groove, making disassembly and assembly very convenient. Since one end of the locking rod is connected to the inner wall of the receiving groove via a return spring, the pulled-out locking rod and locking rod will not separate from the mounting block. Furthermore, the stretched return spring generates a pulling force that pulls the locking rod back into the receiving groove, allowing the locking rod and locking rod to be inserted back into the fixing block. This design prevents the locking rod from being lost and facilitates insertion and removal, enabling workers to quickly disassemble and install the main unit, reducing operation time and improving the device's operational efficiency.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] Example 1, as Figures 1-4 As shown, in order to solve the problem that existing atmospheric visibility detection devices are unable to accurately assess visibility under the influence of atmospheric waveguide effects. This embodiment discloses an atmospheric waveguide sensing visibility assessment device, including a column 1, a mounting block 801, a main unit 3, an adjustment mechanism 7, and a disassembly and assembly mechanism 8. A cavity is provided inside the column, a driven pulley 702 is provided at the top of the cavity, and an active pulley 703 is provided at the bottom of the cavity. One end of the pulley shaft of the active pulley extends out of the column and is connected to a rocker wheel 704. A clearance groove 701 communicating with the cavity is provided on the surface of the column. A movable block 706 that can slide along the clearance groove is provided inside the cavity. A protrusion protruding out of the clearance groove is provided on the movable block. The protrusion is fixedly connected to the back of the mounting block. The top and bottom of the movable block are connected by a connecting rope 705 sleeved between the driven pulley and the active pulley. A sliding groove 802 is provided on the front of the mounting block 801. A fixing block 6 that can be inserted into the sliding groove is provided on the back of the main unit 3. A side support rod 4 is provided on each side of the main unit. A detector 5 is hingedly installed on each side support rod. The detector is a waveguide sensor, which can detect waveguide effects in the atmosphere in real time, thereby assessing visibility changes under different meteorological conditions.
[0027] The active pulley can be rotated by turning the rocker wheel, which in turn moves the connecting rope between the driven pulley and the active pulley. Since the moving block is connected to the connecting rope, the movement of the connecting rope can drive the moving block to slide up and down along the clearance groove. This, in turn, drives the main unit to move up and down through the mounting block that is fixedly connected to the moving block. This allows for flexible adjustment of the height of the main unit and the detector, improving the device's detection flexibility and enabling it to adapt to different weather conditions and measurement needs in real time. This allows for a more accurate perception of the impact of atmospheric waveguide effects on visibility.
[0028] The detector is hinged to the side support rod, which can swing the detector to a specific angle and fix it. The side support rod is set on the main unit, and the height of the detector can be changed by adjusting the height of the main unit. This enables real-time adjustment of the detector's height and angle to adapt to the refractive index changes at different levels in the atmosphere, accurately sense the impact of atmospheric waveguide effects on the light propagation path, and provide accurate visibility assessment.
[0029] A mounting plate 2 is installed at the bottom of the column to stably fix the device to the ground. A scale bar 708 is installed on the outer wall of the column adjacent to the clearance groove, so that the staff has a numerical reference when adjusting the height of the moving block, so as to display the visibility assessment results at different heights.
[0030] like Figure 5 As shown, a fastening bolt 707 is screwed onto the rocker wheel. One end of the fastening bolt passes through the rocker wheel and can be screwed onto the outer wall of the column. When the detection height does not need to be changed, the operator connects the fastening bolt on the rocker wheel to the threaded connection of the column to prevent the rocker wheel from rotating and causing the detector position to change. When the detection height needs to be changed, the connection between the fastening bolt and the threaded connection of the column is released, and the rocker wheel can then be rotated.
[0031] like Figure 6 As shown, a slot 808 that passes through the slide groove and a receiving groove 803 that does not pass through the slide groove are provided on the mounting block. A locking rod 807 that can pass through the fixing block is inserted into the slot, and a limiting rod 805 is inserted into the receiving groove. One end of the limiting rod is connected to the inner wall of the receiving groove through a return spring 804, and the other end is connected to the locking rod through a toggle block 806 exposed outside the mounting block. When the limiting rod is pulled out of the receiving groove, the return spring is stretched and generates a pulling force that pulls the limiting rod back into the receiving groove.
[0032] After the fixing block on the back of the main unit is inserted into the sliding groove on the front of the mounting block, the fixing block is then locked in place by a locking rod to prevent it from moving within the sliding groove. When the main unit needs to be removed, simply pull the lever along with the locking rod to release the locking of the fixing block and slide it out of the sliding groove. Disassembly and assembly are very convenient. Since one end of the locking rod is connected to the inner wall of the receiving groove via a return spring, the pulled-out locking rod and locking rod will not separate from the mounting block. Furthermore, the stretched return spring will generate a pulling force to pull the locking rod back into the receiving groove, allowing the locking rod and locking rod to be inserted back into the fixing block. This design not only prevents the locking rod from being lost but also facilitates its insertion and removal, enabling workers to quickly disassemble and install the main unit, reducing operator time and improving the efficiency of the device.
[0033] When using the device, the staff uses the mounting plate to fix the column on the ground at the location to be detected. The detector is powered by an external power supply. One detector is set as the transmitter and the other as the receiver. The transmitter emits a beam of light of a specific wavelength, which shines into the air. The receiver measures the intensity of the scattered light caused by the air scattering. Combined with the changes in the refractive index in the atmosphere, especially the influence of atmospheric waveguide effect on the light propagation path, the visibility distance is evaluated.
