Technical Field

The invention relates to the technical field of bridge engineering monitoring, in particular to a support.

Background

The support is an important part for bearing the upper part and the lower part of engineering such as a bridge, and the force of the upper part is transmitted to the foundation of the lower part through the support. The bridge at home and abroad is frequently collapsed or locally damaged in the operation and use period or the bridge construction period, and each accident can cause huge loss to the lives and properties of people. The main reason for the collapse of the bridge is that the load borne by the bridge is changed and accumulated to a certain extent by various external factors, and exceeds the bearing capacity of the structure. In order to ensure the stress of the bridge and the running safety of vehicles, the stress state and the use state of the bridge need to be monitored in real time so as to find accident potential in time and eliminate the potential.

At present, the existing monitoring mode is to design a dynamometric support in advance according to bridge construction or design requirements before bridge construction, install the dynamometric support between a bridge and an abutment, and monitor the stress condition of the bridge. The force measuring components such as the sensor of the force measuring support are arranged in the support and are integrated with the support, so that the force measuring support can only be used in the bridge construction process and cannot be used in the constructed bridge.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

The invention aims to provide a sensor and a support, which are used for solving the technical problems in the prior art, can monitor a running bridge in real time and can replace a failed support in time.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The first embodiment is as follows:

fig. 1-3 are schematic structural views of a sensor according to an embodiment of the present application. As shown in fig. 1 to 3, the sensor 1 includes a first housing 11, a second housing 12, and a first monitoring module 13. The second housing 12 is longitudinally movably sleeved in the first housing 11, and the first housing and the second housing form a first accommodating cavity. The first monitoring module 13 is disposed in the first accommodating cavity and used for monitoring and acquiring sensor data. When the first housing 11 and the second housing 12 are subjected to an external force, the first housing 11 and the second housing 12 can move longitudinally relative to each other, so as to drive the first monitoring module 13 to move in the first accommodating cavity for monitoring and acquiring sensor data.

The first housing 11 includes a first opening 111, and the first opening 111 is disposed downward. The second housing 12 includes a second opening 121, and the second opening 121 is disposed upward. The cross-sectional dimension of the second opening 121 is smaller than the cross-sectional dimension of the first opening 111, so that the second housing 12 is sleeved in the first housing 11, and the second housing and the first housing surround to form a first accommodating cavity with variable volume. Preferably, elastic members having elasticity such as springs are provided in the first housing 11 and the second housing 12, and the first housing 11 and the second housing 12 can be in the first state and the second state by the elastic members. In the first state, that is, when no external force is applied to the first housing 11 and the second housing 12, the elastic member is not subjected to force; the second state is that the first housing 11 and the second housing 12 are moved relatively by the elastic force of the elastic member after receiving an external force. When the external force disappears, the first housing 11 and the second housing 12 are switched from the second state to the first state by the elastic force of the elastic member. The first housing 11 and the second housing 12 may be provided in a cylindrical opening structure having an arbitrary shape in cross section. Preferably, the first housing 11 and the second housing 12 are provided in a cylindrical opening structure.

The first monitoring module 13 includes a first monitoring unit 131 and a second monitoring unit 132. The first monitoring unit 131 is disposed in the first housing 11 and is fixedly connected to the top of the first housing 11. The second monitoring unit 132 is disposed in the second housing 12, and is opposite to the first monitoring unit 131. When the first housing 11 is subjected to a downward external force, the first housing 11 drives the first monitoring unit 131 to move downward, and a relative distance between the first monitoring unit 131 and the second monitoring unit 132 changes, so that the sensor data obtained by monitoring changes.

In this embodiment, the first monitoring unit 131 is a laser transmitter, and the second monitoring unit 132 is a laser receiver. The laser receiver is arranged opposite to the laser transmitter along a laser emission light path of the laser transmitter and used for receiving laser and converting received light energy into electric energy, then corresponding electric signal parameters are sent to the data processor in a wireless or wired mode to be processed and analyzed, whether the bridge is in a normal load bearing range is judged, and measures such as maintenance, reinforcement and the like are taken in time according to the stress state of the bridge. In this embodiment, the material of the laser receiver is graphene, which can absorb photon energy. The laser receiver is characterized in that a metal electrode is evaporated on the graphene layer and is connected with a detection circuit through the metal electrode. The working principle of the laser receiver is that a Schottky barrier is formed at a contact part of metal and graphene, and in a space electric field area of the Schottky barrier, surplus electrons and holes excited by light are separated by an electric field to form photocurrent. When the relative distance between the laser transmitter and the laser receiver is different, the laser receiver receives different photon energy, and the generated photocurrent is different.

In this embodiment, the laser emitter is fixedly connected to the first housing 11 through a fixing rod 133, and is disposed in a central area of the first housing 11. The laser emitting path of the laser emitter 131 is horizontal and parallel to the bottom surface of the second housing 12, as indicated by the arrows in fig. 1 and 2. The laser receiver is fixed on the inner wall of the second shell 12 along the laser emission optical path, so that the laser emitted by the laser emitter is positioned in the laser receiving range of the laser receiver. Wherein, the surface of the laser receiver for receiving the laser is arranged to have a certain slope from top to bottom, i.e. the surface forms a predetermined included angle α with the bottom surface of the second housing 12, as shown in fig. 1. In this embodiment, the predetermined included angle α is smaller than 90 degrees or greater than 90 degrees, when an external force is applied to the first housing 11 and the second housing 12, and the first housing 11 and the second housing 12 move relatively, the distance from the laser emitted by the laser emitter to the surface of the laser receiver changes, so that the intensity of the light received by the laser receiver changes, and further the internal electrical signal changes, and the electrical signal is transmitted to the data processor for calculation and analysis, so as to calculate the external force borne by the first housing 11 and the second housing 12.

Preferably, the laser receiver may be provided as a columnar structure having a through hole provided therein, a surface of the through hole being for receiving the laser light. The outer wall of the laser receiver is the same shape as the inner wall of the second housing 12 so that the laser receiver and the second housing 12 can be fixedly connected more closely. The through hole in the laser receiver can be a circular truncated cone structure. Preferably, the upper end surface of the circular truncated cone structure is larger than the lower end surface, as shown in fig. 2. When the first housing 11 and the second housing 12 are subjected to a complex external force, the first housing 11 drives the laser transmitter to generate lateral deviation, and the laser receiver can still receive laser at the moment, so that the purpose of monitoring is achieved.

In another implementation, the laser emission optical path of the laser emitter is vertical and perpendicular to the bottom surface of the second housing 12, as shown by the arrow in fig. 3. The laser receiver is arranged in a plane structure and fixed on the bottom surface of the second housing 12 along the laser emission optical path, so that the laser emitted by the laser emitter is located in the laser receiving range of the laser receiver, as shown in fig. 3. When the shell is stressed, the laser transmitter and the laser receiver are driven to move relatively, so that the relative distance from the laser transmitted by the laser transmitter to the laser receiver is changed, the laser receiver can change the internal electric signal, the electric signal is transmitted to the data processor for operation and analysis, and the bearing load of the shell is calculated. Preferably, the size of the laser receiver is the same as that of the bottom surface of the second housing 12, and when the laser transmitter moves laterally, the laser receiver can still receive laser, so that the sensor acquires sensor data, and the monitoring accuracy of the sensor is improved.

Example two:

the present embodiment differs from the first embodiment only in that the first monitoring module 13 of the sensor 1 is different, specifically: the first monitoring unit 131 is a laser transceiver, and the second monitoring unit 132 is a laser reflector, as shown in fig. 4. The working principle of the laser transmitting and receiving all-in-one machine is that a laser transmitting unit and a laser receiving unit are arranged in the same direction to form an integral structure. When the laser emitting unit is electrified to emit laser, the laser is reflected to the laser receiving unit through the laser reflector, so that a circuit connected with the laser receiving unit is conducted, and an electric signal is generated. Wherein, the laser emitting unit can be a laser emitting diode, and the laser receiving unit can be a photosensitive diode or the like.

In this embodiment, the laser transmitter-receiver is fixedly connected to the first housing 11 through a fixing rod 133, and a laser transmitting light path of the laser transmitter-receiver is perpendicular to the bottom surface of the second housing 12. The laser reflector is arranged in a planar structure and fixed on the bottom surface of the second housing 12 along the laser emission optical path, so that the laser emitted by the laser emission unit is positioned in the laser receiving and reflecting range of the laser reflector, as shown in fig. 4. When the shell is stressed, the laser transmitting and receiving all-in-one machine and the laser reflector are driven to move relatively, so that the relative distance from the laser transmitted by the laser transmitting and receiving all-in-one machine to the laser reflector is changed, meanwhile, the angle of the laser reflected by the laser reflector is also changed, the intensity of the light received by the laser receiving unit is changed, the internal electric signal is further changed, the electric signal is transmitted to the data processor for operation and analysis, and the bearing load of the shell is calculated. Preferably, the size of the laser reflector is the same as that of the bottom surface of the second shell 12, and when the laser transmitting and receiving all-in-one machine moves transversely, the laser reflector can still receive laser to reflect, so that the sensor acquires data of the sensor, and the monitoring accuracy of the sensor is improved.

Example three:

the present embodiment differs from the first and second embodiments only in that the first monitoring module 13 of the sensor 1 is different, specifically: the first monitoring unit 131 is a grating sliding rod, and the second monitoring unit 132 is a grating detection device. The grating sliding rod is fixedly connected with the first shell 11 and is perpendicular to the bottom surface of the second shell 12. The optical grating detection device is fixed on the bottom surface of the second housing 12 through a fixing seat 134, and a detection hole 1321 is formed thereon, as shown in fig. 5. The grating sliding rod is coaxial with the detection hole 1321, the diameter of the detection hole 1321 is larger than that of the grating sliding rod, and the grating sliding rod can move longitudinally along the detection hole 1321.

The grating slide bar has grating stripes. The grating detection device comprises a light source, a convergent lens, an indication grating, a photoelectric element, a driving circuit and the like. When the grating sliding rod moves longitudinally along the detection hole 1321, an included angle is formed between grating stripes of the grating sliding rod and grating stripes of the indication grating, and light and dark stripes are formed under the irradiation of a light source. Along with the relative movement of the grating sliding rod and the indication grating, the formed light and dark stripes move along with the relative movement, and different light and dark stripes are directly irradiated on the photoelectric element to output different digital pulse signals.

When the housing is stressed, the first housing 11 of the sensor drives the grating sliding rod and the grating detection device to move relatively, digital pulse signals are output, and the digital pulse signals are processed and analyzed by the data processor, so that various forces borne by the first housing 11 and the second housing 12 are calculated. The embodiment detects through the grating, and has the characteristics of high detection precision and high response speed.

Example four:

the present embodiment is different from the first, second, and third embodiments only in that the first monitoring module 13 of the sensor 1 is different, specifically: the first monitoring unit 131 is a magnetic conductive device, and the second monitoring unit 132 is an excitation coil. The magnetic conduction device is an iron rod or an iron core, is fixed in the first shell 11, and is perpendicular to the bottom surface of the second shell 12. The excitation coil is disposed opposite to the magnetic conductive device and fixed to the bottom surface of the second housing 12. The coil dimensions of the exciter coil are larger than the magnetically permeable means, which are relatively movable within the exciter coil, as shown in fig. 6. The magnet exciting coil generates a magnetic field after being electrified, and when the magnetic conduction device moves relatively in the magnet exciting coil, the magnetic resistance can be changed, so that the current in a circuit connected with the magnet exciting coil is changed.

When the shell is stressed, the first shell 11 drives the magnetic conduction device to move relatively in the excitation coil, and at the moment, the magnetic conduction of the excitation coil changes, so that the current in a circuit connected with the excitation coil is changed. The second monitoring unit transmits the current signal to a data processor for processing and analysis, so as to calculate various forces borne by the first shell 11 and the second shell 12.

Example five:

the present embodiment is different from the first, second, third and fourth embodiments only in that the first monitoring module 13 of the sensor 1 is different, specifically: the first monitoring unit 131 is a trigger device, and the second monitoring unit 132 is a resistance strain device. The trigger device is used for applying force to the resistance strain device so as to enable the resistance strain device to deform and further change the resistance of the resistance strain device. The triggering device can be a rod-shaped structure, and the end part of the triggering device is provided with a circular structure so as to avoid damaging the resistance strain device. The trigger device is fixed in the first housing 11 and is perpendicular to the bottom surface of the second housing 12. The resistive strain device is disposed opposite the trigger device and is fixed to the bottom surface of the second housing 12, as shown in fig. 7 and 8.

The resistance strain device comprises a resistance strain support A, a strain circuit B (not shown in the figure) and a resistance strain gauge C. The resistance strain gauge C is disposed on the top of the resistance strain bracket a, so that when the trigger device 131 and the resistance strain device 132 move relatively, the trigger device 131 and the resistance strain gauge C can directly contact each other, and further the resistance strain gauge C deforms to change the resistance. The strain circuit B is arranged in the resistance strain bracket A and is electrically connected with the resistance strain gauge C. When the resistance strain gauge C deforms, the resistance changes, and the voltage or current in the strain circuit B is changed. In this embodiment, the resistance strain bracket a is provided in a cylindrical shape, the top portion thereof has good elasticity, and the resistance strain gauge C is adhered to the surface of the top portion, as shown in fig. 8. When the resistance strain gauge C is subjected to external force, the resistance strain gauge C can deform along with the top of the resistance strain support A, and damage to the resistance strain gauge C is avoided. In another implementation manner, the top of the resistance strain bracket a may be provided as a hollow structure, and the resistance strain gauge C is provided on the top of the resistance strain bracket a, and the resistance strain gauge C is larger than the area of the top of the resistance strain bracket a, as shown in fig. 7. When the resistance strain gauge C is subjected to external force, the resistance strain gauge C moves into the hollow structure of the resistance strain support A and deforms.

When the shell is stressed, the first shell 11 drives the trigger device and the resistance strain device to move relatively, at the moment, the trigger device applies external force to the resistance strain gauge, the resistance strain gauge C deforms, the resistance changes, and voltage or current in the strain circuit B is further changed. The current or voltage signal is transmitted to a data processor for processing and analysis, so as to calculate the external force borne by the first shell 11 and the second shell 12.

Example six:

the present embodiment differs from the first to fifth embodiments only in that the first monitoring module 13 of the sensor 1 is different, specifically: the first monitoring unit 131 is a movable plate, and the second monitoring unit 132 is a fixed plate. The movable pole plate is fixed to the first housing 11 by a fixing rod 133. The fixed plate is disposed on the inner wall of the second casing 12, and is disposed opposite to the movable plate in parallel to form a capacitor, as shown in fig. 9. When the movable polar plate and the fixed polar plate move transversely relatively, the voltage between the movable polar plate and the fixed polar plate changes.

When the housing is subjected to an external force, the first housing 11 drives the movable polar plate and the fixed polar plate to move relatively, so that the voltage between the movable polar plate and the fixed polar plate changes. The voltage signal is transmitted to a data processor for processing and analysis, so as to calculate the external force borne by the first shell 11 and the second shell 12.

Example seven:

fig. 10 is a schematic structural diagram of a sensor according to an embodiment of the present application. The present embodiment is different from the first to sixth embodiments in that the sensor 1 further includes a second monitoring module 14, a third housing 15, and a fourth housing 16. The fourth casing 16 is disposed on the top of the first casing 11, and has one side fixedly connected to the first casing 11 and the other side provided with a fourth opening 161. Wherein a gap 17 is formed between the fourth housing 16 and the top of the first housing 11, so that the third housing 15 can be sleeved on the outer side of the fourth housing 16 in a laterally movable manner. Preferably, the height of the gap 17 is the same as the wall thickness of the third housing 15.

In this embodiment, the first monitoring module 13 and the second monitoring module 14 have the same structure, and may have the same structure as any one of the first monitoring module 13 in the first to sixth embodiments. The first monitoring module 13 is mounted in the same manner as in the first to sixth embodiments. The second monitoring module 14 is mounted in a manner perpendicular to the first monitoring module 13. The second monitoring module 14 includes a third monitoring unit 141 and a fourth monitoring unit 142.

Preferably, elastic members having elasticity such as springs are provided in the third casing 15 and the fourth casing 16, and the third casing 15 and the fourth casing 16 can be in the first state and the second state by the elastic members. In the first state, that is, when no external force is applied to the third casing 15 or the fourth casing 16, the elastic member is not subjected to a force; the second state is that the third casing 15 and the fourth casing 16 are subjected to an external force and then relatively move in the lateral direction by the elastic force of the elastic member. When the external force disappears, the third casing 15 and the fourth casing 16 are switched from the second state back to the first state by the elastic force of the elastic member. The third and

fourth housings

15 and 16 may be provided in a cylindrical or square opening structure. Preferably, the third and

fourth housings

15 and 16 are provided in a square opening structure.

When the shell is subjected to a longitudinal external force, the third shell 15 transmits the external force to the first shell 11, so that the first shell 11 and the second shell 12 move longitudinally relative to each other, the distance between the first monitoring unit 131 and the second monitoring unit 132 is shortened, corresponding sensor data is generated and sent to the data processor for analysis and processing, and the magnitude of the longitudinal external force applied to the current shell can be obtained.

When the shell is subjected to a lateral external force, the third shell 15 and the fourth shell 16 move laterally relative to each other, the distance between the third monitoring unit 141 and the fourth monitoring unit 142 is shortened, and the currently acquired sensor data is sent to the data processor for analysis and processing, so that the magnitude of the lateral external force applied to the current shell can be obtained.

When the shell is subjected to the transverse external force and the longitudinal external force simultaneously, the third shell 15 and the fourth shell 16 move transversely relative to each other, and the third shell 15 transmits the longitudinal external force to the first shell 11, so that the first shell 11 and the second shell 12 move longitudinally relative to each other, and at the moment, the data processor can calculate the specific condition of the current external force applied to the shell according to the sensor data acquired by monitoring through the first monitoring module 13 and the second monitoring module 14.

The cross sections of the upper supporting plate 2 and the lower supporting plate 3 are larger than that of the main body part 4, so that the outer side of the main body part 4 and the upper supporting plate 2 and the lower supporting plate 3 form a communicated groove D. That is, the upper support plate 2, the lower support plate 3 and the main body 4 have an i-shaped cross section in any longitudinal direction. The sensor 1 is arranged in the groove D (i.e. in the frame on both sides of the i-shaped structure) and is detachably arranged between the upper support plate 2 and the lower support plate 3, as shown in fig. 13. Wherein, it is provided with first recess 21 and second recess 31 respectively to go up backup pad 2 and the relative one side of bottom suspension fagging 3, the top and the bottom of sensor 1 are embedded in first recess 21 and second recess 31 respectively, make sensor 1 is fixed in go up between backup pad 2 and the bottom suspension fagging 3. When the upper support plate 2 and the lower support plate 3 are subjected to relative movement by an external force, the sensor 1 may be used to detect the external force applied to the upper support plate 2 and the lower support plate 3.

In this embodiment, the structure of the sensor 1 may be the same as any one of the sensor structures of the first to seventh embodiments. When the sensor 1 is configured to have the same structure as that of the first embodiment to the sixth embodiment, the first recess 21 corresponds to the top structure of the first housing 11 of the sensor 1, and the second recess 31 corresponds to the bottom structure of the second housing 12 of the sensor 1, as shown in fig. 15 and 16. When the sensor 1 is configured to be the same as the sensor structure in the seventh embodiment, the first recess 21 is adapted to the top structure of the third housing 15 or the fourth housing 16 of the sensor 1, and the second recess 31 is adapted to the bottom structure of the second housing 12 of the sensor 1, as shown in fig. 17.

In this embodiment, the support may comprise a plurality of sensors 1. A plurality of sets of first grooves 21 and second grooves 31, which are the same in number as the sensors 1, are provided on opposite sides of the upper support plate 2 and the lower support plate 3, respectively. A plurality of sensors 1 are respectively fixed in the first recess 21 and the second recess 31.
