Description

Technical Field

[0001] This utility model relates to the field of wind direction and anemometer technology, specifically a wind direction and anemometer for a cross-river bridge deck. Background Technology

[0002] An anemometer is a meteorological instrument that measures wind direction and speed in real time using mechanical or electronic sensing technology. Its core components are a wind vane (indicating the direction of incoming wind) and a wind speed sensor (such as a rotating wind cup or ultrasonic probe). The wind cup rotates due to wind power, and its rotational speed is proportional to the wind speed.

[0003] However, when installing wind direction and speed meters, due to the height of the cross-river bridge, the equipment is mostly installed at high places or on the outer edge. Maintenance requires long-term high-altitude operations or traffic closure, resulting in long maintenance cycles and delayed fault repair. At the same time, when installing wind direction and speed meters on the bridge deck, the traditional mains power supply wiring is difficult, and the dust brought by passing vehicles on the bridge deck can cause insufficient power supply when the solar panels are covered with dust, affecting continuous monitoring.

[0004] Therefore, a wind direction and speed meter for cross-river bridges is needed to improve the above-mentioned problems. Utility Model Content

[0005] This invention provides a wind direction and speed meter for a cross-river bridge deck to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind direction and speed meter for a cross-river bridge deck includes a fixed column, a fixing component mounted on the bottom outer wall of the fixed column, a control cabinet mounted on the outer wall of the fixed column, a wireless transmission antenna mounted on the outer wall of the control cabinet, a mounting bracket mounted on the outer wall of the fixed column, a wind speed sensor mounted on the outer wall of the mounting bracket, a servo motor mounted on the outer wall of the fixed column, a top rod mounted on the drive shaft of the servo motor, a wind direction sensor mounted on the top outer wall of the top rod, a mounting frame mounted on one side of the wind direction sensor and located on the outer wall of the top rod, and a photovoltaic module mounted on the outer wall of the mounting frame.

[0008] As a preferred embodiment of this utility model, the fixing component includes a fixing upper plate and a fixing lower plate. The fixing upper plate is fixed to the bottom outer wall of the fixing column by bolts. A fixing shell is arranged in a ring on the outer wall of the fixing upper plate. A limit hole is opened on the bottom outer wall of the fixing shell. A conical limit block is provided on one side of the limit hole and on the inner wall of the fixing shell.

[0009] As a preferred embodiment of this utility model, a conical sleeve is slidably connected to the inner wall of the conical limiting block. An installation groove is formed in an annular shape on the inner wall of the conical sleeve. The installation groove is located on the outer wall of the tip of the conical sleeve. A limiting ball is installed on the inner wall of the installation groove. A limiting ring plate is installed on one side of the installation groove and on the inner wall of the conical sleeve.

[0010] As a preferred embodiment of this utility model, a magnetic adsorption block is provided at the port of the conical sleeve, wherein the magnetic adsorption block is located in the inner cavity of the fixed housing, and a limit spring is installed on the outer wall of the magnetic adsorption block, one end of the limit spring being connected to the inner wall of the fixed housing.

[0011] As a preferred embodiment of this utility model, a fixed guide rod is inserted and pulled into the inner wall of the limiting hole, a limiting arc groove is formed on the outer wall of the fixed guide rod, and a limiting ball is slidably connected to the inner wall of the limiting arc groove.

[0012] As a preferred embodiment of this utility model, a fixed lower plate is installed at one end of the fixed guide rod, wherein multiple sets of fixed guide rods are provided and are respectively located on the outer wall of the fixed lower plate, and the fixed guide rods form a ring structure.

[0013] As a preferred embodiment of this utility model, the photovoltaic module includes a fixed frame, and the fixed frame is provided in two sets and is respectively located on the outer wall of the top rod. A photovoltaic energy storage device is installed on the outer wall of the fixed frame, and a slide rail is installed on the opposite outer wall of the photovoltaic energy storage device.

[0014] As a preferred embodiment of this utility model, a sliding bracket is slidably connected to the inner wall of the slide rail, and a brush plate is installed on the inner wall of the sliding bracket, wherein the brush plate is located directly above the photovoltaic energy storage device, and a wind deflector is installed on the top outer wall of the sliding bracket.

[0015] As a preferred embodiment of this utility model, the control cabinet is electrically connected to a wind speed sensor, a servo motor, a wind direction sensor, and a photovoltaic energy storage device via wires. Two sets of photovoltaic modules are provided and are located on opposite outer walls of the mounting frame. The photovoltaic energy storage device is located on one side of the wind direction sensor.

[0016] Compared with existing technologies, this utility model enables more convenient disassembly and maintenance of the anemometer on the bridge deck of a cross-river bridge by setting a fixed component. The lower plate is fixed to the bridge deck, and the upper and lower plates are quickly aligned by inserting a fixed guide rod into the limiting hole. During installation, the guide rod insertion triggers a linkage mechanism between the limiting ball and the conical sleeve. A limiting spring and a magnetic adsorption block drive the conical sleeve downwards, causing it to lock onto the limiting block for self-locking. During disassembly, an external strong magnet attracts the magnetic block, causing the conical sleeve to move upwards, releasing the ball and releasing the guide rod's limiting position. Multiple fixing columns enhance overall stability, and the magnetic unlocking design improves disassembly and assembly efficiency. This solves the problem that, due to the height of cross-river bridges, the equipment is often installed at high locations or along the outer edges, requiring prolonged high-altitude work or traffic closures for maintenance, resulting in long maintenance cycles and delayed fault repairs.

[0017] This invention, by installing photovoltaic modules in the anemometer on the bridge deck of a cross-river bridge, enables wind-driven baffles to actuate brushes that clean the photovoltaic panels. Environmental data is monitored in real time by wind speed and direction sensors. When the wind speed and direction reach set values, the control cabinet drives a servo motor to rotate the photovoltaic modules, aligning the baffles with the wind direction. As the wind blows the baffles, the sliding bracket, in conjunction with the brushes, cleans the surface of the photovoltaic energy storage device. After a set time, the system automatically resets, achieving adaptive dust removal. This solves the problem of insufficient power supply and disruption to continuous monitoring caused by dust accumulation on solar panels when the anemometer is installed on the bridge deck, due to the difficulty of wiring traditional mains power and the large amount of dust stirred up by passing vehicles.

[0026] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4The fixing assembly 2 includes a fixing upper plate 201 and a fixing lower plate 202. The fixing upper plate 201 is fixed to the bottom outer wall of the fixing column 1 by bolts. A fixing housing 203 is arranged in a ring on the outer wall of the fixing upper plate 201. A limiting hole 204 is opened on the bottom outer wall of the fixing housing 203. A conical limiting block 205 is arranged on one side of the limiting hole 204 and on the inner wall of the fixing housing 203. A conical sleeve 206 is slidably connected to the inner wall of the conical limiting block 205. An installation groove 207 is arranged in a ring on the inner wall of the conical sleeve 206. The installation groove 207 is located on the outer wall of the tip of the conical sleeve 206. A limiting ball 208 is installed on the inner wall of the installation groove 207. A limiting ball 208 is installed on one side of the installation groove 207 and on the outer wall of the conical sleeve 206. A limiting ring plate 209 is installed on the inner wall of the fixed housing 203. A magnetic adsorption block 210 is provided at the end of the tapered sleeve 206. The magnetic adsorption block 210 is located in the inner cavity of the fixed housing 203. A limiting spring 211 is installed on the outer wall of the magnetic adsorption block 210. One end of the limiting spring 211 is connected to the inner wall of the fixed housing 203. A fixed guide rod 212 is inserted and pulled into the inner wall of the limiting hole 204. A limiting arc groove 213 is opened on the outer wall of the fixed guide rod 212. A limiting ball 208 is slidably connected on the inner wall of the limiting arc groove 213. A fixed lower plate 202 is installed on one end of the fixed guide rod 212. Multiple sets of fixed guide rods 212 are provided and are located on the outer wall of the fixed lower plate 202 respectively. The fixed guide rods 212 form a ring structure.

[0027] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 5 The photovoltaic module 10 includes a fixed frame 1001. The fixed frame 1001 has two sets and is located on the outer wall of the top rod 7 respectively. A photovoltaic energy storage device 1002 is installed on the outer wall of the fixed frame 1001. A slide rail 1003 is installed on the opposite outer wall of the photovoltaic energy storage device 1002. A sliding bracket 1004 is slidably connected to the inner wall of the slide rail 1003. A brush plate 1005 is installed on the inner wall of the sliding bracket 1004, wherein the brush plate 1005 is located directly above the photovoltaic energy storage device 1002. A wind deflector 1006 is installed on the top outer wall of the sliding bracket 1004.

[0028] Based on the above structural features and connection relationships, the servo motor 6 has an encoder structure, and the servo motor 6 can sense the magnetic pole position, rotation angle and speed in real time. The photovoltaic module 10 is set with an initial position. When the wind direction is northwest, it is only necessary to make the drive shaft of the servo motor 6 drive the top rod 7 to rotate a certain angle, thereby making the photovoltaic module 10 face northwest.

[0029] The control cabinet 3 is electrically connected to the wind speed sensor 5, servo motor 6, wind direction sensor 8, and photovoltaic energy storage device 1002 via wires, which powers the device and enables the control cabinet 3 to control the operation of the wind speed sensor 5, servo motor 6, wind direction sensor 8, and photovoltaic energy storage device 1002. Two sets of photovoltaic modules 10 are located on opposite outer walls of the mounting frame 9, and the photovoltaic energy storage device 1002 is located on one side of the wind direction sensor 8.

[0030] In this scheme, the wind direction and speed meter on the bridge deck of the cross-river bridge is operated by fixing the lower plate 202 to the bridge deck, and then aligning the fixing housing 203 of the upper plate 201 with the fixing guide rod 212 so that the fixing guide rod 212 is inserted into the limiting hole 204 for fixation. When the fixing guide rod 212 is inserted into the fixing housing 203, the limiting ball 208 is slidably connected to the inner wall of the limiting arc groove 213 of the fixing guide rod 212. Since the conical sleeve 206 and the conical limiting block 205 are slidably connected, and the limiting ball 208 is located at... When the limiting arc groove 213 and the limiting ball 208 come into contact on the outer wall of the tip of the conical sleeve 206, the limiting spring 211 presses the magnetic adsorption block 210 downward, which in turn causes the magnetic adsorption block 210 to move the conical sleeve 206 downward, so that the conical sleeve 206 is stuck at the bottom of the conical limiting block 205. At this time, the outer wall of the conical limiting block 205 presses the limiting ball 208, which causes the limiting ball 208 to press the limiting arc groove 213 in the middle, thereby fixing the fixed guide rod 212, making the device easy to install and fix.

[0031] During disassembly, a strong magnet is simply attached to the outer wall of the fixed housing 203. The magnet and the magnetic adsorption block 210 then magnetically attract each other, causing the magnetic adsorption block 210 to drive the conical sleeve 206 to slide upwards on the inner wall of the fixed housing 203. Simultaneously, the magnetic adsorption block 210 compresses the limiting spring 211, and the conical sleeve 206 moves the limiting ball 208 upwards, causing the limiting ball 208 to disengage from the limiting groove 213. At this point, the fixed guide rod 212 loses the fixation of the limiting ball 208, and can then... The upper fixing plate 201 can be easily pulled out, allowing the upper fixing plate 201 to move the fixing housing 203 out of the fixing guide rod 212, making the installation and disassembly of the device more convenient. The fixing column 1 is fixed on the outer wall of the upper fixing plate 201, allowing the fixing component 2 to be fixed from multiple points, resulting in good stability of the device. This solves the problem that when installing wind direction and anemometers, due to the height of the cross-river bridge, the equipment is mostly installed at high places or on the outer edge, and maintenance requires long-term high-altitude operations or traffic closure, resulting in long maintenance cycles and delayed fault repair.

[0032] Wind speed sensor 5 generates data based on ambient wind speed, causing it to produce an electrical signal that is transmitted to control cabinet 3 via wires. Simultaneously, wind direction sensor 8 generates data based on ambient wind direction, also producing an electrical signal that is transmitted to control cabinet 3 via wires. When both wind direction and wind speed reach set parameters, control cabinet 3 activates servo motor 6. This servo motor 6 starts from its initial position, causing its drive shaft to rotate the push rod 7. The push rod 7 then rotates the mounting bracket 9, which in turn moves the photovoltaic module 10 according to the wind direction. Based on the wind direction, the photovoltaic module 10 moves from its initial position to the position indicated by the wind. The position is such that the wind deflector 1006 faces the wind direction. When the wind deflector 1006 is blown by the wind, it will cause the sliding bracket 1004 to move, which in turn causes the sliding bracket 1004 to slide to one side on the inner wall of the slide rail 1003. This causes the sliding bracket 1004 to drive the brush plate 1005 to brush away the floating dust on the surface of the photovoltaic energy storage device 1002. When the set time parameter is reached, the control cabinet 3 controls the servo motor 6 to reset. This solves the problem that when the wind direction and speed meter is installed on the bridge, the traditional mains power supply wiring is difficult, and there is a lot of dust brought up by passing vehicles on the bridge. When the solar panel is covered with dust, it will cause insufficient power supply and affect continuous monitoring.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
