Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present application, the present application will be described in further detail with reference to fig. 1 to 10.
In the embodiment of the application, a device for measuring the sinking of a fan foundation based on Beidou satellite is provided, which comprises a body 1 (the body refers to a foundation for installing a fan), a tower pole 10 of the fan arranged on the body 1, wherein an optical signal transmitter 11 is arranged on the outer wall of the tower pole 10, an optical signal receiver is arranged on the periphery of the body 1 (the optical signal receiver is arranged on another fixed foundation, so that the position change of the body 1 can not drive the optical signal receiver to change together), and the optical signal receiver receives an optical signal and then transmits the optical signal to a Beidou communication module, and the device further comprises: the dynamic reflection module 2 controls the change of the included angle between the incident light 5 and the reflected light 6 of the optical signal, the length of the incident light 5 is smaller than the length of the reflected light 6, and the dynamic reflection module 2 reflects the incident light 5 onto the optical signal receiver (the fan, the fan body 1, the optical signal transmitter 11 and the optical signal receiver are all in the prior art, and are not described in detail below, and some are not shown in the figure).
Specifically, the volume and weight of the fan are very large, the condition of the body 1 for installing and fixing the fan needs to meet the acting force generated during the operation of the fan so as to ensure the safe and stable operation of the fan, but the body 1 of the fan can be inclined or sunk under the influence of the soil property of the place where the fan is located, and collapse damage of the fan can be caused when the fan is serious, so that the position change of the body 1 of the fan needs to be monitored at any time so as to find out the problem in time, the embodiment uses the optical signal of the optical signal transmitter 11 and the reflecting sheet running on the horizontal plane to represent that the body 1 is in the normal position state, and the embodiment needs to pay attention to the fact that the fan can generate vibration during the operation process, the vibration is allowed during the operation process of the fan, but because the vibration is not oriented, namely the tower 101 can drive the body 1 to incline, and this is also one of the reasons why the tower 101 tilts or sinks, so that an included angle range exists between the optical signal emitted by the optical signal emitter 11 and the horizontal plane, for example, from 2 degrees to-2 degrees (the american standard is 1 degree and 2 degrees respectively, and obviously, dynamic adjustment can be performed based on actual requirements), that is, when the tower 10 drives the optical signal emitter 11 to swing within the range, the optical signal receiver can normally receive the optical signal and transmit the optical signal to the control center through the beidou communication module (the beidou communication module, that is, based on the beidou satellite, the information transmission between the fan foundation safety detection and the control center is realized, so that a staff of the control center can monitor the safety state of the fan foundation at any time), when the tower 10 drives the optical signal emitter 11 to swing within the range of more than 2 degrees to-2 degrees, the optical signal receiver can not receive the optical signal, and then the optical signal receiver can transmit the optical signal to the control center alarm signal through the Beidou communication module.
The fan is not oriented to incline when vibration occurs, the body 1 basically faces to one direction when incline occurs, the sinking is also the case, if the inclination angle of the body 1 is between 2 degrees and-2 degrees, or the sinking distance of the body 1 is within 5cm, the optical signal receiver still can receive the optical signal, but at this time, the body 1 is inclined or sinking, which is a potential safety hazard, and timely monitoring and alarming are required, therefore, in the embodiment, the light beam emitted by the optical signal emitter 11 is reflected by the dynamic reflection module 2 and then is emitted to the optical signal receiver, the dynamic reflection module 2 can reflect the light speed within a certain range, such as a range from 12 degrees to-12 degrees, the receiving range of the optical signal receiver is enlarged, namely, the receiving range is from 2 degrees to 12 degrees and-2 degrees to-12 degrees, the length of the incident light ray 5 is smaller than the length of the reflected light ray 6, when the starting point of the incident light ray 5 is inclined or sinking, the length between the incident light ray 5 and the starting point is also required to be monitored timely, and the normal line of the reflected light ray 6 is also changed, namely, the normal line of the reflected light ray is also from the receiving end point of the body is changed to the end point of the reflected light ray 6, and the normal line of the reflected light ray 6 is also changed from the end point of the body 1 to the receiving end point of the reflected light ray 6, and the normal line is also changed from the normal line of the incident light 6 to the original light 1, and the end point is located at the end point of the reflected light 2 is changed, and the end point is located at the end point of the position of the reflected light point 2, and the normal point is located at the end point, and the normal point of the reflected point is 2, and the normal point is 2, and 2 is.
In this embodiment, the dynamic reflection module 2 can reflect the optical signal within a certain range, and the length of the incident light 5 is smaller than the length of the reflected light 6, that is, the arc length between the starting point of the incident light 5 and the normal is smaller than the arc length between the ending point of the reflected light 6 and the normal, so when the position of the body 1 changes, the position change amplitude of the ending point of the reflected light 6 is necessarily larger than the position amplitude of the starting point of the incident light 5, therefore, the arc length change between the ending point of the reflected light 6 and the normal is used as the reference basis for tilting or sinking of the body 1, and the tilting angle and sinking distance of the body 1 can be obtained according to the calculation method.
Preferably, the dynamic reflection module 2 includes a base 20 disposed at the periphery of the body 1, the base 20 is provided with a plurality of reflection sheets 21 in parallel along the circumferential direction of the tower 10, the optical signal transmitters 11 are disposed in a plurality of numbers in the circumferential direction of the tower 10, the plurality of reflection sheets 21 and the plurality of optical signal transmitters 11 are in one-to-one correspondence, the reflection sheets 21 are driven by a driving member on the base 20 to form a swinging motion, and the optical signal receivers are disposed in each optical signal reflection area, i.e., the plurality of optical signal receivers are also disposed in parallel along the circumferential direction on the base 20.
Specifically, the base 20 is not in contact with the body 1, the body 1 tilts or sinks, even when the body 1 is affected by fan vibration, the base 20 is not affected, the plurality of reflecting plates 21 are arranged in parallel in the circumferential direction of the base 20, that is, the tilting direction of the body 1 cannot be determined, the plurality of reflecting plates 21 can correspond to all directions of the body 1, so that once the body 1 tilts, a part of a light beam emitted by the optical signal emitter 11 inevitably follows the tilting, and thus the light beam reflected by the reflecting plates 21 is inevitably received by the optical signal receiver, and the driving piece drives the reflecting plates 21 to reciprocate on the base 20, for example, the reciprocating swing of the reflecting plates 21 is arranged in the longitudinal direction according to the tilting mode of the body 1.
Preferably, the base 20 itself is also of a split type structure, i.e. comprises a plurality of parts, and each reflecting sheet 21 corresponds to one part of the base 20, so that when one part of the base 20 is deflected, the normal data of the rest part can be verified, and all data anomalies are caused after the deflection of the integral base 20.
The base 20 is provided with a plurality of groups of reflecting chambers 22, each group of reflecting chambers 22 corresponds to one reflecting sheet 21, the number of each group of reflecting chambers 22 is two, the reflecting sheet 21 reflects the reflected light of the upward and downward reflection of the optical signal, and the reflecting chambers 22 reflect the light beam of the optical signal before the optical signal is received by the optical signal receiver.
Preferably, the reflecting plate 21 is hinged to the base 20, a sliding opening 23 is provided on the reflecting plate 21, the driving member includes a pressing ring 24 rotatably provided on the base 20, the sliding opening 23 is slidably connected with the pressing ring 24, a driving source (not shown in the drawing) provided on the base 20 drives the pressing ring 24 to rotate circumferentially, and the inner wall of the sliding opening 23 is pressed during the circumferential rotation stroke of the pressing ring 24 so that the reflecting plate 21 swings reciprocally along the hinge point.
Specifically, in the foregoing, the reciprocal swing of the reflective sheet 21 is set in the longitudinal direction, so that when the reflective sheet 21 is driven to reciprocal swing, the driving source drives the extrusion ring 24 to rotate circumferentially on the base 20, the extrusion ring 24 slides relatively with the sliding opening 23 when rotating, and the extrusion forces acting alternately on the two side walls of the sliding opening 23 in the longitudinal direction are generated, so that the reflective sheet 21 will reciprocally swing along the hinge point due to the extrusion.
Preferably, the pressing ring 24 has a wave-shaped structure, wherein the waves refer to waves in the longitudinal direction, i.e. in the vertical direction, and a part of the pressing ring is higher and a part of the pressing ring is lower; specifically, the extrusion ring 24 is in a wave-shaped structure, the wave crest can longitudinally extrude the upper side wall of the sliding opening 23, the wave trough can longitudinally extrude the lower side wall of the sliding opening 23, in the rotation process of the extrusion ring 24, the reflecting sheet 21 can form reciprocating swing, and then the wave crest and the wave trough can be correspondingly designed and adjusted according to the swing range required by the reflecting sheet 21.
Further, the trough and the crest of the extrusion ring 24 are both straight line segments; specifically, after the wave crest or the wave trough of the extruding ring 24 extrudes the inner wall of the sliding opening 23, along with the continuous rotation of the extruding ring 24, the reflecting sheet 21 does not stop after swinging for a certain angle, so when the body 1 inclines or sinks, the time for receiving the optical signal is shorter, which is unfavorable for the analysis and conversion of the optical signal, therefore, in the embodiment, the wave crest and the wave trough of the extruding ring 24 are arranged as straight line segments, namely, when the wave crest or the wave trough extrudes the wall of the sliding opening 23, the reflecting sheet 21 can stay for a period of time after swinging to the position, so that the optical signal receiver can receive the optical signal for a period of time, and the optical signal is converted into an electric signal for transmission, so that the inclination or sinking information of the body 1 is more definite.
Preferably, the reflective chamber 22 is divided into a safe section 220 and a unsafe section 221, the optical signal receiver emits a safe signal when the incident light 5 is reflected by the reflective sheet 21 to the safe section 220, and emits an alarm signal when the incident light 5 is reflected by the reflective sheet to the unsafe section 221.
Specifically, when the fan works, vibration exists on the fan tower 10, the vibration of the fan tower 10 inevitably affects light emitted by the optical signal emitter 11, so that the light shakes, and vibration is allowed when the fan works, so that when the optical signal reflected by the reflecting sheet 21 irradiates the safety section 220, the fan is indicated to work normally, the optical signal emitted by the optical signal emitter 11 can be emitted by the reflecting sheet 21 normally and received by the optical signal receiver, when the optical signal reflected by the reflecting sheet 21 irradiates the unsafe section 221, the vibration amplitude of the tower 10 is overlarge and exceeds the allowable vibration amplitude, and the body 1 inclines or sinks, and at the moment, the optical signal receiver transmits an alarm signal to the control center through the Beidou satellite.
Further, the base 20 is provided with a plurality of notches 25, each notch 25 corresponds to one optical signal emitter 11, the optical signal emitters 11 are connected with the tower 10 through a first frangible member 26, when the reflected light 6 irradiates the middle or more of the unsafe section 221, the walls of the notches 25 squeeze the optical signal emitters 11 to break the first frangible member 26, and the optical signal emitters 11 fall into the cavity 27 of the base 20.
Specifically, since the length of the incident light 5 is smaller than the length of the reflected light 6, the distance between the optical signal emitter 11 and the reflecting sheet 21 is smaller than the distance between the reflecting chamber 22 and the reflecting sheet 21, when the body 1 is sunk or inclined, the optical signal emitter 11 collides with a certain portion of the base 20, so that the position of the body 1 is changed, and in this embodiment, the optical signal emitter 11 and the tower 10 are connected by a first frangible member 26, that is, when the position of the body 1 is changed, the optical signal emitter 11 contacts with a certain portion of the notch 25 and interacts with the notch to cause the first frangible member 26 to break, so that the connection between the optical signal emitter 11 and the tower 10 is broken, and the optical signal emitter 11 can fall into the cavity 27 on the base 20 to be protected.
The first frangible member 26 is broken under a specified impact force, so that the damage to the optical signal transmitter 11 is minimized, and the vibration of the tower 10 does not cause the breakage of the first frangible member 26, because the optical signal transmitter 11 does not contact any part of the notch 25 in the allowable vibration range of the tower 10.
Preferably, a sliding seat 28 is slidably disposed on the base 20 in the longitudinal direction, and the dynamic reflection module 2, the reflection chamber 22 and the notch 25 are disposed on the sliding seat 28; a plurality of first struts 29 are fixedly connected in parallel in the circumferential direction at the bottom of the sliding seat 28, a plurality of second struts 30 are arranged in parallel in the circumferential direction of the base 20, each second strut 30 is in sliding connection with the base 20 in the radial direction (the tower 10 is generally cylindrical, the radial direction is the radial direction of the tower 10 here), a first wedge surface is arranged on the first struts 29, a second wedge surface is arranged on the second struts 30, a second breakable member 31 is connected between the second struts 30 and the body 1, and under the extrusion action of the second breakable member 31, the first wedge surface abuts against the second wedge surface so that the sliding seat 28 cannot slide up and down on the base 20; when the position of the body 1 changes, the second frangible member 31 is broken by the body 1, and the slider 28 moves up and down on the base 20 to strike the optical signal transmitter 11 so as to break the first frangible member 26.
Specifically, when the position of the body 1 is not changed, or the tower 10 vibrates within an allowable range, the second breakable element 31 is not broken, so that the second breakable element 31 can generate a certain pushing action on the second supporting rod 30, so that the first supporting rod 29 and the second supporting rod 30 cannot be dislocated, that is, the first wedge surface and the second wedge surface can be abutted against each other, the sliding seat 28 can be jacked on the base 20 to move continuously, wherein the second breakable element 31 can be broken by extrusion in a certain aspect, can also be broken after torsion, and is in an arc shape with an upward opening and is obliquely arranged between the body 1 and the second supporting rod 30, that is, when the body 1 is obliquely arranged in a certain direction, a certain extrusion force is generated on the second breakable element 31 at one position in the direction, and a pulling force is generated on the second breakable element 31 at the other position in the direction, the second breakable element 31 can be broken, the second breakable element 31 at the other position can be obliquely acted by the body 1, the second breakable element 31 can be broken by torsion, and the second breakable element 31 can be obliquely arranged at the two ends of the second breakable element 31, and the distance between the second breakable element 31 and the second breakable element 31 can be horizontally arranged at the two ends of the second breakable element 31, and the second breakable element 31 can be obliquely arranged at the two ends of the second breakable element 1.
