Description

Technical Field

[0001] This application relates to the field of meteorological measurement equipment technology, and in particular to a meteorological station snow depth and snow volume measurement equipment. Background Technology

[0002] In meteorological observation, accurate measurement of snow depth and snow volume is of paramount importance for meteorological research, weather forecasting, hydrological monitoring, and disaster prevention and mitigation. Traditional methods of snow depth measurement mainly rely on manual measurement using snow gauges. However, snow gauges cannot be guaranteed to be vertical, and this method is difficult to implement and has low accuracy when the snow accumulation is deep.

[0003] Therefore, many methods of sensing and detection using sensors have emerged, such as measurement using laser sensors, image acquisition sensors, and ultrasonic sensors. Among these measurement methods, laser sensors are more accurate and easier to configure.

[0004] However, existing laser sensors for measuring snow depth and snow volume are all configured independently using brackets, making installation and disassembly quite troublesome when installed outdoors. Utility Model Content

[0005] This application provides a meteorological station snow depth and snow volume measurement equipment to solve the problem that laser sensors require independent brackets and are difficult to install.

[0006] This application provides a snow depth and snow volume measurement device for meteorological stations, which is installed on meteorological stations. The meteorological station includes a horizontally set mounting plate and a control box located on the mounting plate.

[0007] The meteorological station's snow depth and snow volume measurement equipment includes a ring frame, a laser measurement component, and a plug. The ring frame has a receiving groove and a sliding hole formed on opposite side walls, with the sliding hole communicating with the receiving groove. The ring frame and mounting plate are relatively fixed. The laser measurement component is mounted on the ring frame and partially within the receiving groove, with a gap between the laser measurement component and the sliding hole. The plug is slidably positioned within the sliding hole, with its end extending outside the ring frame. The plug and the laser measurement component are electrically connected via a flexible circuit. The mounting plate has a plug-in hole, and the control box has a pin hole communicating with the plug-in hole. The plug can pass through the plug-in hole and slide into the pin hole, thus electrically connecting the laser measurement component to the electrical components inside the control box.

[0008] The laser measurement component in this application is fixedly mounted on a ring frame. The ring frame also has a plug for electrical connection to the laser measurement component. The plug can slide into a pin on the control box, connecting the laser measurement component to the electrical components inside the control box. This allows the electrical components to power the laser measurement component and receive its measurement results. The ring frame in this design is fixed relative to the mounting plate, and the plug allows the laser measurement component to be directly connected to the electrical components inside the control box, eliminating the need for additional supports. The meteorological station snow depth and snowfall measurement equipment provided in this application can be directly plugged into the meteorological station, making installation convenient.

[0009] In some embodiments of this application, the projection of the pin hole is completely within the projection of the plug hole along the axial direction of the plug hole. The area of ​​the pin hole is smaller than the area of ​​the plug hole, which facilitates the free sliding of the plug within the plug hole and the insertion of the plug and the pin hole.

[0010] In some embodiments of this application, a plastic layer is provided on both the outer wall of the plug and the inner annular wall of the pin hole. The two plastic layers can be pressed against each other, thereby ensuring a stable connection between the plug and the pin hole.

[0011] In some embodiments of this application, a plurality of strip-shaped protrusions are formed on the portion of the plug located between the annular frame and the pin hole. The plurality of strip-shaped protrusions are spaced apart around the annular surface of the plug, extend along the axial direction of the plug, and a gap is provided between the strip-shaped protrusions and the annular frame and the pin hole.

[0012] The strip protrusion can be pressed with a tool. After the plug is inserted into the pin hole, the tool can be used to press the strip protrusion to make the plug insert into the pin hole to a predetermined depth, so that the plug and the pin hole can have a stable electrical connection.

[0013] In some embodiments of this application, the projection of the sliding hole lies entirely within the projection of the receiving groove along the axial direction of the sliding hole. The sliding hole is smaller than the receiving groove, which allows the plug to slide freely within the receiving groove at one end located within the annular frame.

[0014] In some embodiments of this application, limiting rings are provided on the annular walls on both sides of the sliding hole, allowing the plug located between the two limiting rings to slide on the sliding hole. The limiting rings restrict the sliding of the plug, preventing it from dislodging from the sliding hole.

[0015] In some embodiments of this application, a gap is provided between the annular wall of the plug and the inner annular surface of the sliding hole, and a sealing ring is provided at the end of the sliding hole. The sealing ring is fixedly connected to the annular frame and slidably connected to the plug. The sealing ring serves two purposes: firstly, it limits the sliding direction of the plug, making the plug sliding more stable; secondly, it prevents water or insects from entering the replacement frame through the gap between the annular wall of the plug and the inner annular surface of the sliding hole, thus protecting the flexible circuitry.

[0016] In some embodiments of this application, the meteorological station snow depth and snow volume measurement equipment further includes multiple fixing plates and multiple connectors. The multiple fixing plates are respectively fixedly mounted on the annular frame. The fixing plates and the openings of the sliding holes are located on the same wall surface of the annular frame. The fixing plates extend outward from the annular frame. Each fixing plate is provided with at least one connector, and the connectors are fixedly connected to the fixing plates and the mounting plates.

[0017] The fixing plate and connectors enable the ring frame to be fixedly connected to the mounting plate, facilitating the installation of the ring frame.

[0018] In some embodiments of this application, 2 to 6 fixing plates are provided, and the multiple fixing plates are distributed at equal intervals around the circumference of the annular frame. The multiple fixing plates can make the connection between the annular frame and the fixing plates stable. Attached Figure Description

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] In meteorological observation, accurate measurement of snow depth and snow volume is of paramount importance for meteorological research, weather forecasting, hydrological monitoring, and disaster prevention and mitigation. Traditional methods of snow depth measurement mainly rely on manual measurement using snow gauges. However, snow gauges cannot be guaranteed to be vertical, and this method is difficult to implement and has low accuracy when the snow accumulation is deep.

[0028] Therefore, many methods of sensing and detection using sensors have emerged, such as measurement using laser sensors, image acquisition sensors, and ultrasonic sensors. Among these measurement methods, laser sensors are more accurate and easier to configure.

[0029] However, existing laser sensors for measuring snow depth and snow volume are all configured independently using brackets, making installation and disassembly quite troublesome when installed outdoors.

[0030] Therefore, this application provides a snow depth and snow volume measurement device for meteorological stations, which is installed on meteorological station 1. Please refer to... Figure 1 The meteorological station 1 includes a horizontally mounted mounting plate 11 and a control box 12 located on the mounting plate 11. Figure 1 Only a portion of mounting plate 11 and control box 12 is shown.

[0031] Please refer to Figure 1 The meteorological station snow depth and snow volume measurement equipment includes a ring frame 2, a laser measurement component 3, and a plug 4.

[0032] Please refer to Figure 1 The ring frame 2 has a receiving groove 21 and a sliding hole 22 formed on its opposite side walls. The sliding hole 22 communicates with the receiving groove 21, and the ring frame 2 and the mounting plate 11 are fixed to each other. The ring frame 2 can be circular, or it can be an outer circle with an inner square or an outer square with an inner circle. The ring frame 2 needs to be made of a rigid material, such as aluminum alloy, or iron-plastic material.

[0033] Please refer to Figure 1 Both the receiving groove 21 and the sliding hole 22 can be countersunk holes, and they can be connected. The opening directions of the receiving groove 21 and the sliding hole 22 can be opposite, and they can be located on the same straight line to facilitate processing design. The sliding hole 22 can be a round hole, and the receiving groove 21 can be a square groove, or the shapes of the sliding hole 22 and the receiving groove 21 can also be designed in other shapes as needed.

[0034] Please refer to Figure 1 The laser measuring component 3 is mounted on the annular frame 2 and partially mounted in the receiving groove 21. A gap is provided between the laser measuring component 3 and the sliding hole 22.

[0035] Please refer to Figure 1 The laser measurement component 3 may include a laser transmitter 31 and a laser receiver 32. The laser transmitter 31 emits a laser beam vertically toward the ground, and the laser receiver 32 receives the laser signal reflected back from the ground. By measuring the time difference between laser emission and reception, and combining this with the speed of laser propagation in air, the distance from the measuring equipment to the ground can be accurately calculated.

[0036] When there is snow, the difference between the distance from the measuring equipment to the snow surface and the distance to the ground is the snow depth. The laser emitter 31 and the laser receiver 32 are mounted on an adjustable bracket. The bracket is driven by a motor to adjust the angle to adapt to the measurement needs under different terrains and snow conditions, ensuring that the laser beam can be perpendicular to the snow surface for measurement and improving measurement accuracy.

[0037] Please refer to Figure 1 Meanwhile, the laser measurement component 3 may also include a microprocessor 33, which can be a microprocessor 33 that is connected to the laser transmitter 31 and the laser receiver 32 for control. It can be connected to the laser transmitter 31 and the laser receiver 32 through a data interface to control the operation of the laser transmitter 31 and the laser receiver 32.

[0038] The laser measurement component 3 and the ring frame 2 can be fixedly connected, and the connection method can be adhesive, snap-fit, or bolt connection.

[0039] Please refer to Figure 1 The plug 4 is slidably disposed within the sliding hole 22, and its end extends outside the annular frame 2. The plug 4 is electrically connected to the laser measurement component 3 via a flexible circuit 41. Since the plug 4 slides within the sliding hole 22, the shape of the plug 4 should correspond to the shape of the sliding hole 22; for example, both can be square or both can be circular.

[0040] Please refer to Figure 1 The plug 4 and the sliding hole 22 can be fitted with a clearance to allow the plug 4 to slide freely. The plug 4 can be made of plastic or rubber; the flexible circuit can include both power supply lines and data lines to facilitate power supply and data transmission.

[0041] Please refer to Figure 1 The mounting plate 11 has a plug hole 111, and the control box 12 has a pin hole 121 that communicates with the plug hole 111. The plug 4 can pass through the plug hole 111 and slide into the pin hole 121 so that the laser measurement component 3 can be electrically connected to the electrical components in the control box 12.

[0042] Mounting plate 11 can be the existing support plate of meteorological station 1, and it can be made of metal, such as iron; control box 12 is usually fixedly mounted on mounting plate 11. The control box 12 can be equipped with electrical components, such as controllers, power supplies, communication components and data processing modules.

[0043] The socket 111 can be a through hole. The shape of the socket 111 can be the same as or different from that of the plug 4. The cross-sectional area of ​​the plug 4 should be smaller than that of the socket 111 so that the plug 4 can slide freely in the socket 111.

[0044] Please refer to Figure 1 The plug hole 121 should be equipped with wiring, which may include power transmission lines connected to the power supply of the electrical components and communication lines connected to the controller, so that after the plug 4 is plugged into the plug hole 121, the electrical components in the control box 12 can directly drive the laser measurement assembly 3 to perform measurement work.

[0045] Please refer to Figure 1 In this application, the laser measurement component 3 is fixedly mounted on the annular frame 2. The annular frame 2 is also equipped with a plug 4 that is electrically connected to the laser measurement component 3. The plug 4 can slide into a pin on the control box 12, electrically connecting the laser measurement component 3 to the electrical components inside the control box 12. This allows the electrical components to supply power to the laser measurement component 3 and receive the detection results from the laser measurement component 3. In this design, the annular frame 2 is fixed relative to the mounting plate 11, and the plug 4 allows the laser measurement component 3 to be directly electrically connected to the electrical components inside the control box 12, avoiding the need for additional supports. The meteorological station snow depth and snowfall measurement equipment provided in this application can be directly plugged into the meteorological station 1, making installation convenient.

[0046] It can be noted that different meteorological stations 1 have different altitudes. Therefore, when the snow depth and snow volume measurement equipment of each meteorological station is assembled with meteorological station 1, the snow depth and snow volume measurement equipment of the meteorological station should be adjusted in order to determine the data of the snow depth and snow volume measurement equipment and the ground, so that snow accumulation can be calculated based on the preset data when snow accumulation occurs.

[0047] Please refer to Figure 1 In some examples, the projection of the pin hole 121 lies entirely within the projection of the plug hole 111 along the axial direction of the plug hole 111. The area of ​​the pin hole 121 is smaller than the area of ​​the plug hole 111, which facilitates the free sliding of the plug 4 within the plug hole 111 and the insertion of the plug 4 into the pin hole 121.

[0048] Please refer to Figure 1 In some examples, a plastic layer 122 is provided on both the outer wall of the plug 4 and the inner annular wall of the pin hole 121. The two plastic layers 122 can be pressed against each other, thereby making the connection between the plug 4 and the pin hole 121 stable.

[0049] In some examples, the plug 4 itself is made of plastic, so the plastic layer 122 on the plug 4 can be the same plastic material as the plug 4 body. This part of the plastic material can be pre-treated to make its surface relatively rough so that it can be stably connected with the pin hole 121.

[0050] Alternatively, the layered structure on the outer wall of the plug 4 and the inner ring wall of the pin hole 121 can also be a rubber layer, which can achieve the same desired effect.

[0051] Please refer to Figure 1 In some examples, the portion of the plug 4 located between the annular frame 2 and the pin hole 121 is also provided with a plurality of strip-shaped protrusions 42. The plurality of strip-shaped protrusions 42 are distributed at intervals around the annular surface of the plug 4. The strip-shaped protrusions 42 extend along the axial direction of the plug 4. A gap is provided between the strip-shaped protrusions 42 and the annular frame 2 and the pin hole 121.

[0052] The strip protrusion 42 can be pressed with a tool. After the plug 4 is inserted into the pin hole 121, the tool can be used to press the strip protrusion 42 so that the plug 4 can be inserted into the pin hole 121 to a predetermined depth, so that the plug 4 and the pin hole 121 can have a stable electrical connection.

[0053] In some examples, the strip protrusion 42 should have an end face to facilitate compression between the tool and the end face of the strip protrusion 42.

[0054] The number of strip protrusions 42 can be 4 to 8. The strip protrusions 42 can be distributed circumferentially around the plug 4, and the spacing between two adjacent strip protrusions 42 can be equal.

[0055] Please refer to Figure 1 In some examples, the projection of the sliding hole 22 lies entirely within the projection of the receiving groove 21 along the axial direction of the sliding hole 22. The sliding hole 22 is smaller than the receiving groove 21, which allows the plug 4 to slide freely within the receiving groove 21 at one end located within the annular frame 2.

[0056] Please refer to Figure 1 In some examples, limit rings 43 are provided on the annular walls on both sides of the sliding hole 22, and the plug 4 located between the two limit rings 43 can slide on the sliding hole 22. The limit rings 43 can restrict the sliding of the plug 4 and prevent it from falling out of the sliding hole 22.

[0057] In some examples, the limiting ring 43 should be configured such that the sliding distance of the plug 4 in the receiving groove 21 is less than the distance between the laser detection component and the sliding hole 22, so as to avoid excessive compression between the plug 4 and the laser detection component, which could lead to failure of the flexible circuit connection.

[0058] Please refer to Figure 1 In some examples, a gap is provided between the annular wall of the plug 4 and the inner annular surface of the sliding hole 22. A sealing ring 44 is provided at the end of the sliding hole 22. The sealing ring 44 is fixedly connected to the annular frame 2 and slidably connected to the plug 4. The sealing ring 44 can limit the sliding direction of the plug 4, making the sliding of the plug 4 more stable. On the other hand, it can prevent water or insects from entering the replacement frame through the gap between the annular wall of the plug 4 and the inner annular surface of the sliding hole 22, thus protecting the flexible circuit 41.

[0059] In some examples, the sealing ring 44 can be one or two. The sealing ring 44 can be a rubber ring, and the shapes of the inner and outer rings of the sealing ring 44 can correspond to the shapes of the sliding hole 22 and the outer wall surface of the plug 4.

[0060] Please refer to Figure 1 In some examples, the meteorological station snow depth and snow volume measurement equipment also includes multiple fixing plates 5 and multiple connectors 6. The multiple fixing plates 5 are respectively fixedly installed on the annular frame 2. The fixing plates 5 and the openings of the sliding holes 22 are located on the same wall surface of the annular frame 2. The fixing plates 5 extend outward from the annular frame 2. Each fixing plate 5 is provided with at least one connector 6. The connector 6 is fixedly connected to the fixing plate 5 and the mounting plate 11.

[0061] The fixing plate 5 and the connector 6 allow the annular frame 2 to be fixedly connected to the mounting plate 11, facilitating the installation of the annular frame 2. The fixing plate 5 and the annular frame 2 can be connected by welding or bonding.

[0062] In some examples, there are 2 to 6 fixing plates 5, which are evenly distributed around the circumference of the annular frame. The multiple fixing plates 5 can make the connection between the annular frame 2 and the fixing plates 5 stable.

[0063] In some examples, there can be four fixing plates 5 or other numbers; the connecting piece 6 can be a bolt. In this case, corresponding through holes can be provided on the fixing plate 5 and corresponding threaded holes 112 can be provided on the mounting plate 11 so that the bolt can fix the fixing plate 5 on the mounting plate 11.

[0064] For example, there may be one or two connectors 6 on each fixed plate 5.

[0065] In some other examples, the fixing plate 5 can be welded or riveted to the mounting plate 11, which also allows the annular frame 2 to be fixed relative to the mounting plate 11.

[0066] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0067] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
