Thus, the structure is simple and the use is convenient.

Therefore, the detector is convenient to carry and simple to use.

The shaft 2 is also provided with a power supply 21 for supplying power to the listening rod.
Example 5
The detector for detecting a fire fighting pipeline as described above, in this embodiment, as shown in fig. 2, the sounding rod is further provided with a gyroscope 6, because the sounding rod needs to be tightly attached to the pipe wall of the fire fighting pipeline when contacting the fire fighting pipeline; however, the fire fighting pipeline is generally higher or narrower in arrangement position, the front end of the listening rod is an arc-shaped rod head which is not transparent, and the contact position of the rod head and the pipeline is located in a visual blind area of a user, so that whether the fire fighting pipeline is tightly attached or not is difficult to judge only through observation of the user, once the angle of the arc-shaped rod head is inclined, the attachment degree of the fire fighting pipeline is reduced greatly, and great uncertainty is brought to measurement of sound signals.
Because present fire-fighting pipeline generally can level or vertical setting, consequently set up the gyroscope at the pole head of listening pole, like this, the user when with arc pole head contact fire-fighting pipeline, can observe whether vertical or level of gyroscope definite pole head, in case the pole head does not keep vertical or level, then can conclude that the inboard of pole head and fire-fighting pipeline's outer wall has the skew of certain angle, then the pole head must not laminate the pipe wall of fire-fighting pipeline this moment. Consequently, the addition of gyroscope, convenient to use person observes listening rod head and the laminating condition of fire pipeline pipe wall to improve the possibility of pole head laminating pipe wall, and then improve the accuracy to the judgement of leakage point.
As shown in fig. 3, the gyroscope 6 includes: an outer cover 61, an outer ring frame 62, an inner ring frame 63, a fixed shaft 64, a pendulum 65, a pressure sensor 66, a spring 67 and a controller (not shown); two symmetrical ends of the outer ring frame 62 are fixed in the outer cover 61 and can rotate around an axis formed by connecting the two fixed ends; the two symmetrical ends of the inner ring frame 63 are fixed on the outer ring frame 62 and can rotate around the axis formed by the two fixed ends; two ends of the fixed shaft 64 are fixed on the inner ring frame 63 and can rotate around an axis formed by connecting the two fixed ends; the middle part of the fixed shaft 64 is provided with a groove 641, and one end of the pendulum bob 65 is clamped in the groove 641 and swings around the axis of the fixed shaft 64; the middle of the fixed shaft 64 is further provided with a semicircular guide rail 69, the semicircular guide rail 69 passes through the pendulum bob 65 to limit the swinging of the pendulum bob 65, the semicircular guide rail 69 is provided with two springs 67, one end of each of the two springs 67 is fixed on the pendulum bob, the other end of each of the two springs 67 is fixed at two semicircular tail ends of the semicircular guide rail 69, the two pressure sensors 66 are respectively arranged at one ends of the two springs 67, which are in contact with the pendulum bob, to detect the pressure at the tail ends of the springs 67, the controller 68 is connected with the pressure sensors 66 to calculate the actual pressure when the pendulum bob 65 stops after processing the pressure signals thereof, convert the actual pressure into the stop position of the pendulum bob and display the stop position through a liquid crystal display screen on the outer side of the outer cover 61.
Wherein, the axis formed by connecting the symmetrical two ends of the outer ring frame 62 is vertical to the axis formed by connecting the symmetrical two ends of the inner ring frame 63.
Wherein, the axis formed by connecting the two symmetrical ends of the inner ring frame 63 is perpendicular to the fixed shaft 64.
Wherein, the plane of the swinging track of the pendulum 65 is perpendicular to the axis of the fixed shaft 64, so that the pendulum 65 is minimally influenced by the fixed shaft 64 during swinging.
When the pendulum 65 is at the middle position of the semicircular rail 69, the springs 67 are both in a natural extension state, and the pressure on the two pressure sensors 66 disposed between the springs 67 and the pendulum 65 is zero.
The outer ring frame is a circular ring, two bulges are symmetrically arranged at two ends of the outer side of the outer ring frame, and the connecting line of the two bulges passes through the circle center of the outer ring frame; the outer cover is provided with round holes corresponding to the two bulges of the outer ring frame, and the bulges are inserted into the round holes, so that the outer ring frame can rotate around an axis formed by connecting the two round holes.
The inner ring frame is also a circular ring, two bulges are symmetrically arranged at two ends of the outer side of the inner ring frame, and the connecting line of the two bulges passes through the circle center of the inner ring frame; the inner side of the outer ring frame is provided with round holes corresponding to the two bulges of the outer ring frame, and the bulges are inserted into the round holes, so that the inner ring frame can rotate around an axis formed by connecting the two round holes.
The fixed shaft is a straight rod, two round holes are formed in the inner side of the inner ring frame, and a connecting line of the round holes penetrates through the circle center of the inner ring frame; two ends of the straight rod are inserted into the two round holes of the inner ring frame, so that the fixed shaft can rotate around an axis formed by connecting the two round holes.
Thus, when the pendulum bob is normally placed, the pendulum bob is positioned at a vertically downward position, and the outer ring frame, the inner ring frame and the fixed shaft are all kept static; after the gyroscope moves, the pendulum bob is no longer located at a vertically downward position, and the pendulum bob can move to the vertically downward position under the action of gravity; because the pendulum bob can only swing perpendicular to the fixed shaft, if the vertical downward position is not on the motion track of the pendulum bob, the pendulum bob still moves to the vertical downward position, and thus, the fixed shaft for limiting the motion track of the pendulum bob is driven to move; because the fixed shaft can only rotate around the axis formed by connecting the two round holes on the inner side of the inner ring frame, the fixed shaft can drive the inner ring frame to move until the motion track of the pendulum bob moves to pass through the vertical downward position.
The middle of the fixed shaft is provided with a bulge, the bulge is internally provided with a groove 641, the groove is a cylindrical hole, and the axis of the groove is overlapped with the axis of the fixed shaft; one end of the pendulum is T-shaped, the top end of the pendulum is a transverse cylinder, the cylinder is inserted into the cylindrical hole and can rotate in the cylindrical hole along the axis of the cylindrical hole, and therefore the motion track of the pendulum can be limited, and the pendulum can swing around the fixed shaft.
A semicircular guide rail 69 is fixed outside the protrusion, and the circle center of the semicircular guide rail is overlapped with the protrusion; the plane of the semicircular guide rail is overlapped with a screen determined by the motion trail of the pendulum bob, and the arc-shaped area of the semicircular guide rail penetrates through the pendulum bob, so that the motion trail of the pendulum bob is overlapped with the arc-shaped area of the semicircular guide rail, and the pendulum bob swings along the semicircular guide rail.
The pendulum bob is fixedly connected with the semicircular guide rail, so that the pendulum bob is just positioned at the middle point of the arc-shaped area of the semicircular guide rail when the pendulum bob is static. (if the pendulum is stationary, the upper part of the semicircular track is not horizontal, i.e. the pendulum is not located at the midpoint of the arc-shaped area, the compression of the two springs is not the same, thus creating a torque force that rotates the pendulum/semicircular track until the upper part of the semicircular track is horizontal, such that the pendulum is located at the midpoint of the mutual area.)
The fixed shaft can rotate around the axis formed by connecting the two round holes of the inner ring frame, so that the semicircular guide rail can also rotate around the axis formed by connecting the two round holes of the inner ring frame to adjust the position of the semicircular guide rail.
If the gyroscope position moves, one or more of the outer ring frame, the inner ring frame and the fixed shaft can rotate under the direct or indirect action of the pendulum bob until the pendulum bob returns to the vertical downward position.
When the pendulum bob is normally placed, the pendulum bob is located at a vertically downward position, the pendulum bob is located at the middle position of the semicircular guide rail at the moment, the two springs connected with the pendulum bob are both in a natural extension state, pressure signals of the two pressure sensors respectively arranged at one ends, in contact with the pendulum bob, of the two springs are both 0, and the pressure signals represent that the springs have no acting force on the pendulum bob at the moment.
The axis of the fixed shaft is aligned, and the swinging of the pendulum bob is perpendicular to the axis when the axis is seen from one end to the other end of the axis; after the gyroscope moves, the position of the pendulum bob is unchanged relative to the position of the gyroscope, but the absolute position of the pendulum bob changes, namely the position of the pendulum bob leaves a vertically downward position, and at the moment, under the action of gravity, the pendulum bob moves to the vertically downward position and stops until the pendulum bob returns to the vertically downward position; in the process that the pendulum bob moves towards the vertical downward position, due to the limitation of the inherent structure, the pendulum bob only swings along the direction vertical to the axis of the fixed shaft, and other movements which can enable the pendulum bob to finally reach the vertical downward position are completed by the movement of the fixed shaft and the like; if the vertically downward position is located at one side of the middle position of the semicircular track, for convenience of description, it is called the left side of the semicircular track (which is simply called a side that is shifted from the middle position of the semicircular track to both ends, and may also be called a right side if necessary, etc.), the pendulum will move to the left side under the action of gravity (the true motion trajectory of the pendulum is complicated, but here, we only describe the change of its position relative to the fixed shaft), at this time, since one end of the two springs is fixed on the pendulum and the other end is fixed at both ends of the semicircular track, the spring fixed at the left side of the pendulum will be fixed at one end and the other end is compressed inwards along with the motion of the pendulum, the compressed spring will apply an elastic force to the right side to the pendulum, and the pressure sensor connected with the spring will be compressed to generate a pressure signal greater than 0, meanwhile, one end of a spring fixed on the right side of the pendulum bob is fixed, the other end of the spring stretches outwards along with the motion of the pendulum bob, the stretched spring can apply elastic force to the right side of the pendulum bob, and a pressure sensor connected with the spring cannot be extruded, so that the pressure signal of the pressure sensor is still 0; at the moment, the pendulum bob is subjected to the elastic force towards the right side of the two springs, the elastic force is opposite to the movement direction of the pendulum bob, and the pendulum bob gradually slows down and stops under the action of the elastic force and finally moves towards the right side under the action of the elastic force; thus, the pendulum is subjected to the dual action of gravity and spring force, wherein gravity and spring force reach equilibrium at a certain point of the pendulum's motion trajectory, on the left side of the equilibrium, the spring force is greater than gravity, on the right side of the equilibrium, the gravity is greater than the spring force, and the pendulum swings on the left and right sides of the position due to gravity, spring force, and inertia, and comes to rest at the equilibrium position. The balance position is not necessarily the position where the pendulum bob vertically faces downwards, but is the position where the gravity and the elastic force reach the balance, and the balance position is changed continuously along with the movement of the fixed shaft, and finally, the balance position is coincided with the vertical downward position of the pendulum bob. In the whole process, the main function of the spring is to increase the main force of the pendulum movement, so that the pendulum can be stopped as soon as possible (the pendulum can slowly stop due to mechanical friction and other resistance forces when moving, but the stopping time of the pendulum is greatly related to the magnitude of the mechanical friction and other resistance forces, if the resistance force is too large, the deviation between the final stopping position and the actual vertically downward position is large, if the resistance force is too small, the time for the pendulum to return to the stopping is long, and if the time interval of the gyroscope movement is less than the time required for returning to the stopping, the pendulum cannot be stopped at all).
When the pendulum bob returns to the vertical downward position, it takes a long time due to inertia, resistance, and the like, which causes trouble in determining the vertical position.
Wherein, the calculation formula of the actual pressure when the pendulum 65 stops is:
wherein the following is defined by the formula:
in the above formula, the actual pressure when the pendulum is stopped is represented, extreme values in the pressure signal are represented, the serial number of the extreme pressure signal is represented, the maximum value of all the serial numbers currently received is represented, the loss ratio of the resistance to the pendulum is represented, the first extreme value, the second extreme value and the second extreme value of the pressure signal generated by one pressure sensor are represented, the first extreme value, the second extreme value and the second extreme value of the pressure signal generated by the other pressure sensor are represented, the loss ratio corresponding to the first extreme value is represented, and the calculated possible pressure when the pendulum is stopped when the first extreme value is determined is represented.
The basic idea is that all resistance force applied to the pendulum in the swinging process is regarded as the same property as friction force, so that the resistance force loss applied to the pendulum is in direct proportion to the swinging length of the pendulum, the pressure sensor measures the compression force of the spring, and the compression force is in direct proportion to the deformation quantity (namely the swinging length of the pendulum), so that the ratio of the energy lost by the pendulum in two adjacent swinging processes to the energy possessed by the pendulum is regarded as a constant, based on which, according to three adjacent extreme pressure signals, a primary loss ratio can be determined, and the average value of a plurality of loss ratios is the loss ratio closest to the actual value; the possible pressure when the pendulum bob stops at the moment is obtained through the loss ratio and the adjacent extreme pressure signals, and the pendulum bob stop is further obtained through all the possible pressuresActual pressure at time of expiration; if the actual pressure is positive, the pendulum bob is located close to when stopped
If the actual pressure is negative, the pendulum bob is far away from the corresponding pressure sensor when stopping
Corresponding pressure sensor, close to
One side of the corresponding pressure sensor.
According to the calculation method, the loss ratio caused by the resistance such as the friction is calculated, so that the influence of the resistance such as the friction on the calculation result is eliminated, the measurement precision is improved, and the system error is reduced; the actual pressure of the pendulum bob when the pendulum bob is static can be calculated through the three extreme pressure signals, so that the stop position of the pendulum bob is quickly obtained, and the measuring speed is greatly improved; after the extreme value pressure signal is increased, the actual pressure of the pendulum bob when the pendulum bob is static can be recalculated, so that the previous result is continuously corrected, the measurement precision is further improved, and the system error is reduced; the operation process is simple, and program resources are saved; the operation process is simplified, the operation time and the program resource are further saved, and the measurement speed is further improved.
By the calculation method, the vertical position can be judged in a very short time after the pendulum bob swings, so that the working efficiency of the whole process is greatly improved.
The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting. It will be understood by those skilled in the art that various changes, modifications and equivalents may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
