[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0017] Embodiment: A beam detector, such as Figure 1 and Figure 2 As shown, the instrument comprises an outer cover 1 and a detection component, a display component and an energy supply component arranged in the outer cover 1. The outer cover 1 is provided with a detection cavity 2 and a hand-held cavity 3 along its length direction. The detection component and the display component are arranged in the detection cavity 2, and the energy supply component is installed in the hand-held cavity 3. The energy supply of the whole instrument is ensured by the energy supply component. When the instrument user detects the internal structure of the wall and pipelines, the hand-held instrument can realize inductive detection of the wall through the detection cavity 2.
[0018] The end of the detection cavity 2 is provided with a plurality of detection holes 4. The detection assembly includes a plurality of induction probe blocks installed in the detection holes 4. The induction probe blocks include induction blocks 5 and signal transmitting probes 6 that cooperate with the induction blocks 5. The induction blocks 5 are provided with electric guide rail blocks 7 for the horizontal sliding of the signal transmitting probes 6. During the real-time detection process, the signal transmitting probes 6 can move horizontally along the electric guide rail blocks 7 synchronously, thereby realizing dynamic and continuous detection of the edges of the detection objects in the wall, improving the precise positioning of the edges of beams, pipes, etc. in the wall, and the opening of the detection hole 4 is provided with a step groove 16, which reduces the influence between adjacent induction probe blocks and improves the working stability and reliability of each independent induction probe block. Considering that the accuracy of departmental wall detection needs to be further improved, a movable sliding roller 13 is provided outside the detection cavity 2 on one side of the detection hole 4, which facilitates the flexible position movement of the detection personnel when the detection instrument is pressed against the wall for measurement, and facilitates the accurate and rapid judgment of the structural conditions and parameter measurement in the wall.
[0019] The display component includes a signal receiving block 8 and an electronic display screen 9 which are respectively connected to a plurality of sensing probe blocks. The electronic display screen 9 includes a plurality of independent liquid crystal display bars. The wall feedback signal measured by the detection component is analyzed and processed by the signal receiving block 8. Whether there is a supporting beam under the measured surface is confirmed according to the strength of the sensing signal, and the parameters measured by each sensing probe block are displayed through each independent liquid crystal display bar. The detection personnel judge the position and approximate outline of the beam in the wall by the strength of each group of signal spectrum. The stronger the signal, the higher the spectrum line, that is, the position of the beam is determined; the weaker the signal, the lower the spectrum line, that is, the position of the beam in the wall is fuzzy and the edge of the beam needs to be further determined. If the signal is zero, the existence of the beam in the wall is not detected. It is simple to use and easy to read.
[0020] Taking into account the convenience of operation of the detection personnel during actual use, the detection component also includes outline indicator lights 14 arranged on both sides of the instrument cover 1, that is, during real-time detection, the outline indicator lights 14 can instantly mark the outline of the detection area, which is convenient for the detection instrument user to judge and accurately locate the target object according to the feedback of the display component and the on-site conditions.
[0021] A power cavity 10 is provided in the middle of the hand-held cavity 3. The energy supply component includes a battery block 11 and an emergency power interface 12 provided in the power cavity 10. The battery block 11 is relied upon to maintain reliable operation of the entire detector. At the same time, the emergency power interface 12 ensures the operation of an external power supply under unstable power supply, and is suitable for working under indoor conditions.
[0022] In order to further improve the ease of use and reliability of the detection instrument, an anti-slip edge 17 is provided on the outer wall of the hand-held cavity 3 to reduce the offset error in the measurement activity and ensure reliable accuracy; at the same time, an elastic buffer block 15 is provided on the outside of the detection cavity 2 to help reduce the vibration generated by the placement and removal of the instrument during use, which affects the detection accuracy and service life of the sensing probe block and reduces hardware damage caused by external force vibration.
[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
