Description
Technical Field
The invention relates to the technical field of wind speed monitoring, in particular to a wind speed sensor.
Background
In recent years, a power transmission tower frequently suffers from a reverse tower accident due to typhoons. The tower falling accident seriously affects the stable operation of the power grid. Therefore, wind speed monitoring on the power transmission line has important significance for guaranteeing the safety of the power grid. The traditional wind speed monitoring method is to acquire regional wind speed information issued by a meteorological department. However, the regional wind speeds released by the meteorological department are very different from the wind speeds actually suffered by the iron tower, so that workers cannot effectively predict the occurrence of accidents. Therefore, the conventional wind speed monitoring method has a problem of poor accuracy.
Disclosure of Invention
Based on this, it is necessary to provide a wind speed sensor with good accuracy against the problem of poor accuracy.
The wind speed sensor comprises a sensor body, a blade, a signal acquisition module, a signal processing module and a signal transmitting module, wherein the sensor body is provided with an air duct, a first end of the air duct is provided with an air outlet, and a second end of the air duct is provided with an air inlet; the blades are arranged in the air duct; the signal acquisition module is used for acquiring a rotating speed signal of the blade; the input end of the signal processing module is connected with the output end of the signal acquisition module, and the signal processing module is used for converting the rotating speed signal into a wind speed signal; the input end of the signal transmitting module is connected with the output end of the signal processing module, and the signal transmitting module is used for transmitting the wind speed signal.
In the wind speed sensor, wind enters the air channel from the air inlet, blows blades arranged in the air channel, and leaves the air channel from the air outlet of the air channel. There is a positive correlation between wind speed and rotational speed of the blades. The wind speed is high, and the rotating speed is high. Through one or more modes of mathematical derivation, empirical formula, experimental test or simulation calculation, the staff can obtain the corresponding relation between the rotating speed of the blade and the wind speed. Therefore, the signal processing module can convert the rotational speed signal of the blade into a wind speed signal. The signal transmitting module transmits the obtained wind speed signal to monitoring personnel. Therefore, compared with regional wind speed information issued by a meteorological department, the wind speed sensor is used for being installed at a position of a wind speed point to be detected, such as a power transmission tower, a building or a telegraph pole, and the like, and the wind speed information at a specific position can be detected, so that the accuracy is good.
In one embodiment, a wind shielding piece is arranged at the air inlet, and an air inlet part is arranged on the wind shielding piece. The wind shielding piece is arranged at the air inlet, and when wind passes through the air inlet, the wind speed is reduced, so that the wind pressure at the air inlet is greater than the wind pressure at the air outlet. Due to the existence of pressure difference, wind automatically fills the air channel from the air inlet part, drives the blades to rotate and leaves the air channel from the air outlet.
In one embodiment, the wind shield is a wind shield provided with one or more air inlet holes. When wind passes through the wind shield, the wind speed is reduced due to the blocking of the wind shield, and the wind pressure at the air inlet is greater than the wind pressure at the air outlet. Due to the pressure difference, wind automatically enters the air duct from the air inlet of the wind shield.
In one embodiment, the wind speed sensor further comprises a cover plate and a connecting rod, wherein one end of the connecting rod is connected to the first end of the air duct, and the other end of the connecting rod is connected with the cover plate. When the wind speed sensor is installed, the first end of the air channel is positioned above the second end of the air channel. The cover plate is arranged above the first end of the air duct. Thus, the cover plate resists the wind in the vertical direction to pass through the air duct. As shown in fig. 2, the vertical direction refers to the erection direction of the pylon. The horizontal direction refers to a direction parallel to the ground. The wind in the horizontal direction can pass through the first end of the air duct and the second end of the air duct and pass through the air duct under the action of pressure difference, thereby rotating the blades. The wind speed sensor can measure the wind speed in the horizontal direction according to the rotation speed of the blades. For power pylon, wind in the horizontal direction is the main cause of collapse of the pylon. Therefore, the wind speed sensor can measure the speed of wind in the horizontal direction by filtering the wind in the vertical direction through the cover plate, so that the occurrence probability of the collapse accident of the iron tower can be predicted more accurately and measures can be taken earlier.
In one embodiment, the wind speed sensor further includes a generator, a rotor of the generator is connected with the blade, the generator is electrically connected with the signal acquisition module, the generator is electrically connected with the signal processing module, and the generator is electrically connected with the signal transmitting module. The transmission tower is usually arranged in a region with small population density, so that electricity is not conveniently taken. The blades rotate to drive the rotor of the generator to rotate, so that the generator generates electricity and provides power for the signal acquisition module, the signal processing module and the signal transmitting module, and further, the battery replacement at the position of the transmission tower before a worker is reduced or avoided. Therefore, the wind speed sensor can adapt to the outdoor environment, and the burden of staff can be reduced.
In one embodiment, the wind speed sensor further comprises a first anchor ear, a first screw rod and a second screw rod, wherein the first anchor ear clamps the generator, one end of the first screw rod is connected to one side of the first anchor ear, the other end of the first screw rod is connected to the sensor body, one end of the second screw rod is connected to the other side of the first anchor ear, and the other end of the second screw rod is connected to the sensor body. In this way, the generator is mounted to the sensor body. The staff adjusts first screw rod and second screw rod, can adjust first staple bolt and control the removal, the position of being convenient for adjust generator and blade in the wind channel.
In one embodiment, a first rubber member is arranged at the joint of the first screw rod and the sensor body, and/or a second rubber member is arranged at the joint of the second screw rod and the sensor body. The friction force between the first screw rod and the sensor body is increased by the first rubber piece, so that the first screw rod is connected with the sensor body more firmly. Similarly, the second rubber piece makes the second screw rod and the sensor body be connected more firmly. When the wind speed sensor is installed on the power transmission tower, the generator and the blades are firmly connected to the sensor body through the first screw rod and the second screw rod, and cannot fall off from the sensor body, so that the wind speed sensor can work normally. Under extreme weather such as storm or typhoon, the blades work normally, so that the wind speed sensor can measure wind speed information under the extreme weather, and is favorable for accurately analyzing bearing capacity of the power transmission tower or collapse accidents of the power transmission tower.
In one embodiment, the signal processing module is provided with a filter circuit and an amplifying circuit, the filter circuit is used for noise reduction processing of the wind speed signal, the amplifying circuit is used for amplifying energy of the wind speed signal, and the signal transmitting module is provided with a wireless communication transmitter for wireless transmission of the wind speed signal.

In one embodiment, the signal processing module is provided with a comparison circuit, and the comparison circuit is used for comparing the wind speed value of the wind speed signal with a preset wind speed value; and when the wind speed value of the wind speed signal is smaller than a preset wind speed value, the comparison circuit sends a dormancy signal to the signal transmitting module. And determining a preset wind speed value by a worker according to the mechanical design strength of the power transmission tower.

Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
As shown in fig. 1 and 2, a wind speed sensor includes a sensor body 100, a blade 200, a signal acquisition module 300, a signal processing module 400, and a signal transmission module 500. The sensor body 100 is provided with an air duct 101. An air outlet 102 is arranged at a first end of the air duct 101, and an air inlet 103 is arranged at a second end of the air duct 101. The blades 200 are mounted within the air duct 101. The signal acquisition module 300 is used for acquiring a rotational speed signal of the blade 200. An input end of the signal processing module 400 is connected with an output end of the signal acquisition module 300. The signal processing module 400 is configured to convert the rotational speed signal into a wind speed signal. The input end of the signal transmitting module 500 is connected with the output end of the signal processing module 400, and the signal transmitting module 500 is used for transmitting a wind speed signal.
In the wind speed sensor, wind enters the wind channel 101 from the wind inlet 103, blows the blades 200 disposed in the wind channel 101, and leaves the wind channel 101 from the wind outlet 102 of the wind channel 101. There is a positive correlation between wind speed and rotational speed of blade 200. The wind speed is high and the rotational speed of the blade 200 is high. Through one or more of mathematical derivation, empirical formula, experimental test or simulation calculation, the staff can obtain the corresponding relation between the rotation speed of the blade 200 and the wind speed. Accordingly, the signal processing module 400 can convert the rotational speed signal of the blade 200 into a wind speed signal. The signal transmitting module 500 transmits the obtained wind speed signal to a monitoring person. Therefore, compared with regional wind speed information issued by a meteorological department, the wind speed sensor is used for being installed at a position of a wind speed point to be detected, such as a power transmission tower 600, a building or a telegraph pole, and the like, and the wind speed information at a specific position can be detected, so that the accuracy is good.
Specifically, the blade 200 is provided with a rotation shaft. The signal acquisition module 300 acquires a rotational speed signal of the blade 200 by measuring the rotational speed of the rotational shaft.
The wind speed sensor is used to measure wind loads experienced by pylon 600 in extreme weather. The meteorological department uses a blade type anemometer to measure wind speed. However, the fan blade type anemometer has abrasion loss in the rotation process, is easy to be worn by wind and sand, and is easy to be disturbed by freezing, rain and snow. In the wind speed sensor, the blades 200 are arranged in the air duct 101, so that the interference of freezing or rain and snow is avoided, and the adaptability is high.
Further, as shown in fig. 1, a wind shielding member 104 is provided at the wind inlet 103. The wind shielding member 104 is provided with an air inlet 105. The wind shield 104 is arranged at the wind inlet 103. When wind passes through the air inlet portion 105, the wind speed is reduced, so that the wind pressure at the air inlet 103 is greater than the wind pressure at the air outlet 102. Due to the pressure difference, wind automatically fills the air channel 101 from the air inlet 105, drives the blades 200 to rotate, and leaves the air channel 101 from the air outlet 102. The blade 200 is rotated by the pressure difference, not directly blown by external wind, so that the blade 200 encounters wind having a smaller intensity than that of the wind outside the sensor body 100, and can be adapted to extreme weather conditions without damage. Thus, the wind speed sensor has good wind resistance.
Specifically, as shown in fig. 1, the wind shield 104 is a wind shield. The wind shield is provided with more than one air inlet hole. When wind passes through the wind shield, the wind speed is reduced due to the blocking of the wind shield, so that the wind pressure at the wind inlet 103 is greater than the wind pressure at the wind outlet 102. Due to the pressure difference, wind automatically enters the wind channel 101 from the wind inlet of the wind shield.
Further, the staff can control the quantity of the air inlet holes on the wind shield, or control the opening or sealing of the air inlet holes. For example, the number of the air inlet holes is plural. The sealing element is detachably arranged at the air inlet hole. A sealing member blocks an air inlet, so that the air inlet area of the wind shield is reduced. When the sealing element is detached from the wind shield, the air inlet area of the wind shield is increased. For another example, the wind deflector is provided with a turntable. The turntable rotates to shield the air inlet hole, so that the air inlet area of the wind shield is reduced. Through changing the rotation direction and the rotation angle of the turntable, the air inlet area of the wind shield can be reduced or increased by staff. Thus, the staff can control the air inlet area of the wind shield. According to the intensity of wind in extreme weather and the mechanical properties of the blades 200, the staff changes the air inlet area of the wind shield, thereby changing the pressure difference at both ends of the air duct 101, and the intensity of wind in the air duct 101 does not damage the blades 200. Similarly, there is a one-to-one correspondence between the rotational speed of the blade 200 and the wind speed experienced by the pylon. Through one or more of mathematical derivation, empirical formula, experimental test or simulation calculation, the staff can obtain the corresponding relation between the rotation speed of the blade 200 and the wind speed. Therefore, the wind speed sensor cannot be damaged in extreme weather, and the wind speed can be measured normally.
It will be appreciated that the windscreen 104 may also be a textile or porous member having apertures, such as cloth or sponge. The air inlet 105 is referred to as an air inlet hole or air inlet aperture. When wind passes through the wind shielding member 104, the speed of the wind is reduced due to the obstruction of the wind shielding member 104, resulting in an air pressure difference at both ends of the air duct 101. At the same time, wind can enter the wind tunnel 101 from the aperture or hole of the wind shield 104.
On the basis of the foregoing embodiment, as shown in fig. 1 and 2, the wind speed sensor described above further includes a cover plate 106 and a connecting rod 107. One end of the connecting rod 107 is connected to the first end of the air duct 101, and the other end of the connecting rod 107 is connected to the cover plate 106. When the wind speed sensor is installed, the first end of the wind channel 101 is located above the second end of the wind channel 101. A cover plate 106 is mounted over the first end of the air chute 101. In this way, the cover 106 resists the passage of vertically oriented wind through the duct 101. The horizontally-oriented wind may pass through the first end of the wind tunnel 101 and the second end of the wind tunnel 101 and pass through the wind tunnel 101 under the pressure difference, thereby rotating the blades 200. The wind speed sensor can measure the wind speed in the horizontal direction according to the rotation speed of the blade 200. For pylon 600, the horizontal direction of wind is the primary cause of collapse of pylon 600. Therefore, the wind speed sensor filters wind in the vertical direction through the cover plate 106, and can measure the speed of the wind in the horizontal direction, so that the occurrence probability of the iron tower collapse accident can be predicted more accurately, and measures can be taken earlier.
On the basis of the foregoing embodiment, as shown in fig. 1 and 2, the wind speed sensor described above further includes a generator 210. The rotor of the generator 210 is connected to the blades 200. The generator 210 is electrically connected with the signal acquisition module 300, the generator 210 is electrically connected with the signal processing module 400, and the generator 210 is electrically connected with the signal transmission module 500. Pylon 600 is typically located in a small population area and is not convenient for power harvesting. The rotation of the blades 200 drives the rotor of the generator 210 to rotate, so that the generator 210 generates electricity and provides power for the signal acquisition module 300, the signal processing module 400 and the signal transmitting module 500, thereby reducing or avoiding the replacement of the battery at the position where the worker goes to the power transmission tower 600. Therefore, the wind speed sensor can adapt to the outdoor environment, and the burden of staff can be reduced.
On the basis of the foregoing embodiment, as shown in fig. 1, the wind speed sensor further includes a first anchor ear 108, a first screw 109, and a second screw 110. First anchor ear 108 holds generator 210. One end of the first screw 109 is connected to one side of the first anchor ear 108, and the other end of the first screw 109 is connected to the sensor body 100. One end of the second screw 110 is connected to the other side of the first anchor ear 108, and the other end of the second screw 110 is connected to the sensor body 100. As such, the generator 210 is mounted to the sensor body 100. The staff adjusts first screw 109 and second screw 110, can adjust first staple bolt 108 and remove about, the position in wind channel 101 of the generator 210 of being convenient for and blade 200.
Further, as shown in fig. 1, a first rubber member 111 is provided at a connection portion of the first screw 109 and the sensor body 100, and/or a second rubber member 112 is provided at a connection portion of the second screw 110 and the sensor body 100. The first rubber member 111 increases friction between the first screw 109 and the sensor body 100, so that the first screw 109 is more firmly connected with the sensor body 100. Similarly, the second rubber member 112 makes the connection between the second screw 110 and the sensor body 100 more secure. For example, the first rubber member 111 or the second rubber member 112 may be a silicone rubber sheet. When the wind speed sensor is mounted on the pylon 600, the generator 210 and the blade 200 are firmly connected to the sensor body 100 by the first screw 109 and the second screw 110, and do not fall off from the sensor body 100, so that the wind speed sensor can work normally. In extreme weather such as heavy rain or typhoon, the blade 200 is operated normally, so that the wind speed sensor described above can measure wind speed information in extreme weather. Acquiring wind speed information in extreme weather is advantageous for further accurate analysis of the bearing capacity of pylon 600 or the cause of collapse of pylon 600.
On the basis of the foregoing embodiment, as shown in fig. 2, the signal processing module 400 is provided with a filter circuit and an amplifying circuit. The filter circuit is used for noise reduction processing of the wind speed signal. The amplifying circuit is used for amplifying the wind speed signal. The signal transmitting module 500 is provided with a wireless communication transmitter for wirelessly transmitting the wind speed signal. Thus, the wind speed signal is subjected to noise reduction and amplification treatment and is transmitted to a monitoring station or a terminal of a monitoring person through wireless communication.
On the basis of the foregoing embodiment, as shown in fig. 2, the signal processing module 400 is provided with a comparison circuit. The comparison circuit is used for comparing the wind speed value of the wind speed signal with a preset wind speed value. When the wind speed value of the wind speed signal is smaller than the preset wind speed value, the comparison circuit sends a dormancy signal to the signal transmitting module 500. According to the mechanical design strength of the power transmission tower 600, a worker determines a preset wind speed value. When the wind speed is smaller than the preset wind speed value, the power transmission tower 600 is safe and reliable, the signal processing module 400 and the signal transmitting module 500 are in a dormant state, the wind speed signal at the moment is not required to be transmitted, noise reduction or amplification processing is not required to be carried out on the signal, the power consumption of the signal processing module 400 and the signal transmitting module 500 can be saved, and the service life of the wind speed sensor is prolonged.
During actual use, pylon 600 is less likely to experience extreme weather conditions. Under normal conditions, the pylon 600 will not collapse and the staff does not need to monitor wind speed in real time. For example, the preset wind speed value may be 15m/s according to the mechanical design strength of the pylon 600. When the wind speed is less than the preset wind speed value, the signal processing module 400 sends a sleep signal to the signal transmitting module 500, so that the signal transmitting module 500 does not need to transmit the wind speed signal in real time, but periodically generates the sleep signal, which indicates that the wind speed sensor operates normally and the wind speed is less than the preset wind speed value. When the wind speed is greater than or equal to the preset wind speed value, the signal processing module 400 transmits an activation signal to the signal transmitting module 500, so that the signal transmitting module 500 transmits a wind speed signal in real time to inform the staff, so that the staff can predict the occurrence of accidents in time.
On the basis of the foregoing embodiments, as shown in fig. 1 and 2, the wind speed sensor further includes a bracket for connection with the pylon 600. The bracket is connected to the sensor body 100. The sensor body 100 is a tube. The pipe body has simple structure and easy installation. The wind speed sensor is conveniently and quickly installed on the power transmission tower 600 through the bracket.
Specifically, as shown in fig. 1, the pipe body is made of an acrylic plate or a stainless steel plate. The acrylic plate or the stainless steel plate can be suitable for extreme weather environment, can resist cold and heat, and has good rigidity and strength. In addition, the acrylic plate is a transparent plate, so that maintenance personnel can observe the running condition of the blade 200 in the sensor body 100 conveniently, and the wind speed sensor can be inspected conveniently.
Specifically, the tube body can be split into a first housing and a second housing. The first housing and the second housing are connected into a tube body by a second hoop 113. Thus, the tube can be disassembled to facilitate the installation of the blade 200 into the air duct 101.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
