Description

Technical Field

[0001] This invention relates to the field of snow cover measurement technology, specifically to a roof snow thickness monitoring device. Background Technology

[0002] In railway ancillary buildings such as railway stations, signal towers, and power supply workshops, the thickness of snow accumulation on roofs is a key indicator affecting the structural safety of buildings and the stability of railway operations. Designing specialized monitoring equipment has multiple practical implications.

[0003] Traditional manual snow inspection methods for rooftops suffer from high risks associated with working at heights and limited monitoring range. Designing automated rooftop snow depth monitoring equipment enables full-coverage, all-weather monitoring of building rooftops along railway lines. Data is transmitted in real-time to the operations and maintenance center via a professional railway meteorological service system, helping managers dynamically grasp snow conditions in different areas, accurately allocate snow removal resources, reduce manual labor, and improve emergency response speed. Especially in snowy winter regions, this significantly reduces operations and maintenance costs and safety risks.

[0004] Existing railway snow measurement equipment (such as ground-deployed ultrasonic snow meters and laser snow meters) or general-purpose roof snow measurement devices present significant problems in monitoring railway building roofs. Due to the significant differences between the roof environment and the ground, strong winds easily lead to uneven snow accumulation. At the measurement level, existing devices are mostly fixed single-point or single-measurement devices, unable to dynamically adapt to uneven snow surfaces, and do not remove outliers, resulting in insufficient accuracy. Furthermore, in terms of structure, they are functionally limited, have low automation, require manual operation, and are difficult to adapt to long-term monitoring. They also ignore uneven snow levels, have weak anti-interference capabilities, and poor data reliability. These shortcomings restrict their accurate monitoring in complex roof environments. Summary of the Invention

[0005] The purpose of this invention is to provide a roof snow thickness monitoring device to solve the problem that the existing roof snow thickness monitoring devices are difficult to eliminate errors in complex environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roof snow thickness monitoring device, comprising a bracket and a support platform fixedly mounted on the bracket, and further comprising: a mounting base rotatably connected to the support platform; a measuring component slidably connected vertically to one side of the mounting base, the measuring component comprising a measuring unit and a sliding part fixedly connected thereto; a rotating cylinder rotatably connected to the support platform and having a corrugated groove on its circumference, the rotating cylinder being driven to rotate by a driving component; and a locking component for alternately locking the mounting base to the support platform and the rotating cylinder; when the locking component locks the mounting base and the support platform, only the rotating cylinder rotates, and the rotating cylinder slides through the corrugated groove and the sliding part to make the measuring unit reciprocate vertically to measure snow accumulation; when the locking component locks the mounting base and the rotating cylinder, the rotating cylinder drives the mounting base and the measuring component to rotate together, thereby switching the measuring area of ​​the measuring unit along the circumference of the support platform.

[0007] Furthermore, the locking assembly includes a locking rod slidably connected to the mounting base, an elastic element disposed between the locking rod and the mounting base, a magnetic block fixedly connected to the locking rod, and an electromagnet disposed on the mounting base; the rotating cylinder has multiple positioning slots a arranged in a ring array, and the support platform has multiple positioning slots b arranged in a circumferential array, with each positioning slot a corresponding to each positioning slot b. When the elastic element recovers its deformation, it can drive the locking rod to insert into the positioning slot b. When the electromagnet is powered to attract the magnetic block, it causes the locking rod to overcome the elastic force of the elastic element and insert into the positioning slot a.

[0008] Furthermore, the elastic element includes a compression spring movably sleeved on the locking rod, with one end of the compression spring abutting against the magnetic block and the other end abutting against the mounting base.

[0009] Furthermore, the measuring unit includes a support rod, on which a camera and a vertically arranged measuring ruler are fixedly connected. The camera is used to capture the scale of the measuring ruler when it is inserted into the snow.

[0010] Furthermore, the support platform has multiple windows arranged in a circular array, and each window contains a snow container; the measuring unit includes a tray and a weighing device on the tray. When the measuring component rotates with the mounting base, the weighing device can be placed directly below each snow container in sequence. When the measuring unit moves upward along the mounting base, the weighing device lifts up the snow container.

[0011] Furthermore, the support platform has multiple windows arranged in a circular array, and each window contains a snow tray. The measuring unit includes a tray and a weighing device and a snow cutting board placed on the tray. When the measuring unit rotates with the mounting base, the weighing device and the snow cutting board are positioned directly below each snow tray in sequence. When the measuring unit moves upward along the mounting base, the snow cutting board cuts the snow on the snow tray from the surrounding snow, and the weighing device lifts the snow tray.

[0012] Furthermore, the support platform has multiple windows arranged in a circular array, each window containing a snow tray, and each window has a snow-cutting plate vertically slidably connected to its inner periphery. The measuring unit includes a tray and a weighing device mounted on the tray. When the measuring unit rotates with the mounting base, the weighing device is positioned directly below each set of snow trays and snow-cutting plates. When the measuring unit moves upward along the mounting base, the tray lifts the snow-cutting plate upward, and the rising snow-cutting plate cuts the snow on the snow tray from the surrounding snow, while the weighing device lifts the snow tray.

[0013] Furthermore, a snowproof roof is fixedly connected to the rotating cylinder.

[0014] Furthermore, a protective mesh frame is fixedly fitted onto the support platform.

[0015] In the above technical solution, the roof snow thickness monitoring device provided by this invention, when the mounting base and the support platform are locked, the rotating cylinder rotates, and by controlling the sliding engagement of the waveform groove and the sliding part, it drives the measuring unit to move in the vertical direction, thereby accurately measuring the snow accumulation. When the mounting base and the rotating cylinder are locked, the rotation of the rotating cylinder will drive the mounting base and the measuring unit to rotate synchronously, realizing the switching of the measuring unit to the measuring area on the support platform. By collecting snow thickness data from multiple measuring areas, the average value is calculated, and finally more accurate and reliable snow accumulation data is obtained.

[0019] 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.

[0020] Example 1 Please see Figures 1-3 This invention provides a roof snow thickness monitoring device, comprising a bracket 1, a support platform 11, a mounting base 2, a measuring component 4, a rotating cylinder 3, and a locking component 5. The bracket 1 is connected to the roof, the support platform 11 is fixedly mounted on the bracket 1, the mounting base 2 is cylindrical, and both the mounting base 2 and the rotating cylinder 3 are rotatably connected to the support platform 11. The rotation axis of the mounting base 2 is coaxial with the rotation axis of the rotating cylinder 3. A vertical slide rail 21 is provided on one side of the mounting base 2. The measuring component 4 is vertically slidably connected to one side of the mounting base 2 through a sliding engagement between a slider and the vertical slide rail 21. The measuring component 4 includes a measuring unit 41 and a sliding part 42 fixedly connected to each other. In this embodiment, the specific structural unit for measurement includes a support rod 411, on which a camera 412 and a vertically arranged measuring ruler 413 are fixedly connected. The camera 412 is used to capture the scale of the measuring ruler 413 inserted into the snow. The rotating cylinder 3 has a wave groove 31 on its periphery. The bottom of the sliding part 42 is slidably engaged with the wave groove 31 through a sliding column. The support platform 11 or the bracket 1 is also provided with a driving component. The driving component is used to drive the rotating cylinder 3 to rotate. The driving component is preferably a servo motor. The base of the servo motor is fixedly installed on the bracket 1 or the support platform 11. The output shaft 32 is coaxially fixedly connected to the rotating cylinder 3, so that the servo motor can drive the rotating cylinder 3 to rotate intermittently.

[0021] The locking assembly 5 is used to alternately lock the mounting base 2 to the support platform 11 and the rotating cylinder 3. When the locking assembly 5 locks the mounting base 2 and the support platform 11, only the rotating cylinder 3 rotates. The rotating cylinder 3 slides with the sliding part 42 through the corrugated groove 31, causing the measuring unit 41 to reciprocate vertically to measure the snow accumulation. Specifically, when the sliding part 42 moves down along the corrugated groove 31, the measuring ruler 413 is inserted into the snow on the support platform 11. The camera 412 acquires the scale of the measuring ruler 413 on the snow surface, thereby obtaining the snow thickness data. Based on the snow thickness data, the snow weight per unit area can also be calculated. When the sliding part 42 moves up along the corrugated groove 31, the measuring ruler 413 is pulled out of the snow. When the locking component 5 locks the mounting base 2 and the rotating cylinder 3, the rotating cylinder 3 drives the mounting base 2 and the measuring component 4 to rotate together, thereby switching the measuring area aligned with the measuring unit 41 along the circumference of the support platform 11, realizing the switching of the measuring area on the support platform 11 by the measuring unit 41. By collecting snow thickness data from multiple measuring areas, the average value is calculated, and finally more accurate and reliable snow data is obtained.

[0022] See Figures 4-5 The locking assembly 5 specifically includes a locking rod 52, an elastic element, a magnetic block 51, and an electromagnet 54. The mounting base 2 has a mounting groove 22. The locking rod 52 is slidably connected to the mounting base 2 in the mounting groove 22 along the radial direction of the mounting base 2. The magnetic block 51 is fixedly connected to the locking rod 52 and located in the mounting groove 22. The electromagnet 54 is mounted on the mounting base 2 and located in the mounting groove 22. The rotating cylinder 3 has multiple positioning slots a55 arranged in a ring array along its circumference, and the support platform 11 has multiple positioning slots b56 arranged in a circular array. Each positioning slot a55 corresponds to each positioning slot b56. An elastic element is disposed in the mounting slot 22. When the electromagnet 54 is de-energized, the elastic element recovers its deformation, driving the locking rod 52 to insert into the positioning slot b56, thereby locking the mounting base 2 and the support platform 11. When the electromagnet 54 is energized, it attracts the magnetic block 51, causing the locking rod 52 to overcome the elastic force of the elastic element and insert into the positioning slot a55, and the elastic element to recharge, thereby locking the mounting base 2 and the rotating cylinder 3. The elastic element is preferably a compression spring 53, which is movably sleeved on the locking rod 52. One end of the compression spring 53 abuts against the magnetic block 51, and the other end abuts against the side wall of the mounting slot 22.

[0023] It should be added that the waveform of the wave groove 31 is a trapezoidal wave. The characteristic of a trapezoidal wave is that the wave shape resembles a trapezoid, consisting of a top platform, a bottom platform, and rising and falling edges connecting the two. The top and bottom platforms are horizontal straight line segments with a certain linear length, while the rising and falling edges are inclined line segments. The purpose of setting the trapezoidal wave groove with top and bottom platforms is to increase the time that the sliding part 42 spends at the highest and lowest positions of the wave groove 31, and to avoid the situation where the rotating cylinder 3 does not stop rotating immediately when the sliding part 42 moves to the extreme position of the wave groove 31.

[0024] A snowproof top 33 is also fixedly connected to the rotating cylinder 3. The top surface of the snowproof top 33 is arc-shaped. When the mounting base 2 rotates together with the rotating cylinder 3, the support rod 411 rotates with the snowproof top 33. The snowproof top 33 helps to enhance the stability of the rotation of the mounting base 2, and the snowproof top 33 also has a certain wind resistance, which helps to protect the support rod 411 of the measuring unit 41 from being blown or deformed by strong winds. The support platform 11 is designed with a circular structure for snow accumulation. A protective net frame 12 is fixedly fitted around the support platform 11. The protective net frame 12 protects the surface of the support platform 11 and helps the snow to accumulate evenly on the support platform 11.

[0025] Example 2 The difference between this embodiment and other embodiments lies in the specific structure of the measuring unit 41 and the method of measuring snow accumulation. (See also...) Figures 6-8 The support platform 11 has multiple windows 111 arranged in a circular array. It is preferable to have 3-6 windows 111. Each window 111 has a snow container 416 attached to it. The opening of the snow container 416 is slightly larger than the window 111, and snow accumulates in the snow container 416. The measuring unit 41 includes a tray 415 and a weighing device 414 mounted on the tray 415. When the locking assembly 5 locks the mounting base 2 and the rotating cylinder 3, the rotating cylinder 3 drives the mounting base 2 and the measuring assembly 4 to rotate together, so that the weighing device 414 can be placed directly below each snow container 416 in sequence, that is, the measuring unit 41 is aligned with different measuring areas; when the locking assembly 5 locks the mounting base 2 and the support platform 11, only the rotating cylinder 3 rotates. The rotating cylinder 3 slides with the sliding part 42 through the wave groove 31 to make the measuring unit 41 move vertically, so that the weighing device 414 can lift the snow container 416 when it rises. The weighing device 414 measures the total mass of the snow container 416 and the snow inside. The mass of the snow inside the snow container 416 is obtained by subtracting the weight of the snow container 416 from the total mass. Based on the area S of the bottom of the snow container 416 and the density ρ of the snow under the current temperature and humidity, the snow thickness l = m / (ρ * S) can be calculated.

[0026] Example 3 The difference between this embodiment and other embodiments lies in the specific structure of the measuring unit 41 and the method of measuring snow accumulation. (See also...) Figure 9The support platform 11 has multiple windows 111 arranged in a circular array. Each window 111 contains a snow collection tray 4161, and each window 111 is fixedly connected to a support rod 418. The snow collection tray 4161 rests on the support rod 418, and the surface of the snow collection tray 4161 is flush with the surface of the support platform 11. This makes the snow accumulation on the support platform 11 and the snow collection tray 4161 form a whole, resulting in more even snow accumulation and minimal impact of the snow collection tray 4161 on the snow accumulation. The measuring unit 41 includes a tray 415 and a weighing device 414 and a snow cutting plate 417 mounted on the tray 415. The snow cutting plate 417 forms a ring-shaped plate structure that is slightly larger than the outline of the snow collection tray 4161. The height of the snow cutting plate 417 is higher than that of the weighing tray, and the snow cutting plate 417 also has a groove 419 to avoid the support rod 418.

[0027] When the locking assembly 5 locks the mounting base 2 and the rotating cylinder 3, the rotating cylinder 3 drives the mounting base 2 and the measuring assembly 4 to rotate together, thereby enabling the weighing device 414 and the snow-cutting plate 417 to be positioned directly below each snow container 416 in sequence, that is, the measuring unit 41 is aligned with different measuring areas; when the locking assembly 5 locks the mounting base 2 and the support platform 11, only the rotating cylinder 3 rotates, and the rotating cylinder 3 slides with the sliding part 42 through the wave groove 31 to make the measuring unit 41 move vertically, thereby causing the snow-cutting plate 417 and the weighing device 414 to rise together. The snow-cutting board 417 first cuts the snow on the snow-collecting tray 4161 from the surrounding snow, making the snow on the snow-collecting tray 4161 independent and unaffected by the surrounding snow. Then, the weighing device 414 lifts the snow-collecting tray 4161 and measures the total mass of the snow-collecting tray 4161 and the snow on it. The mass of the snow on the snow-collecting tray 4161 is obtained by subtracting the weight of the snow-collecting tray 4161 from the total mass. Based on the area S of the snow-collecting tray 4161 and the density ρ of the snow under the current temperature and humidity, the snow thickness l = m / (ρ * S) can be calculated.

[0028] Example 4 The difference between this embodiment and Embodiment 3 lies in the installation position of the snow-cutting blade 417. (See also...) Figures 10-11The support platform 11 has multiple windows 111 arranged in a circular array. Each window 111 has a snow tray 4161 attached to it. The snow cutting board 417 is vertically slidably connected to the corresponding window 111. The snow cutting board 417 has a groove 419 that avoids the support rod 418. The support rod 418 and the groove 419 form a sliding fit. The measuring unit 41 includes a tray 415 and a weighing device 414 installed on the tray 415. When the locking assembly 5 locks the mounting base 2 and the rotating cylinder 3, the rotation of the rotating cylinder 3 causes the measuring unit 41 to rotate with the mounting base 2, so that the weighing device 414 is placed directly below each set of snow trays 4161 and snow cutting boards 417 in sequence; when the locking assembly 5 locks the mounting base 2 and the support platform 11, the rotation of the rotating cylinder 3 causes the measuring plate and the weighing device 414 to move upward along the mounting base 2. First, the tray 415 lifts the snow cutting board 417 upward, and the rising snow cutting board 417 lifts the snow accumulated on the snow trays 4161. The snow is separated from the surrounding snow, making the snow on the snow collection tray 4161 independent and unaffected by the surrounding snow. Then, the weighing device 414 lifts the snow collection tray 4161 and measures the total mass of the snow collection tray 4161 and the snow on it. The mass of the snow on the snow collection tray 4161 is obtained by subtracting the weight of the snow collection tray 4161 from the total mass. Based on the area S of the snow collection tray 4161 and the density ρ of the snow under the current temperature and humidity, the snow thickness l = m / (ρ * S) can be calculated.

[0029] It should be noted that, unlike the measurement method of the detection component in Embodiment 1, the sliding part 42 moves from one top platform of the trapezoidal wave of the waveform groove 31 to the next top platform as one measurement cycle, that is, the sliding part 42 drives the detection component to descend and then rise to complete one measurement. For the measurement method of the detection component in Embodiments 2, 3, and 4, the sliding part 42 moves from one bottom platform of the trapezoidal wave of the waveform groove 31 to the next bottom platform as one measurement cycle, that is, the sliding part 42 drives the detection component to rise and then descend to complete one measurement.

[0030] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
