[0023] As Figure 1 shown, a kind of optical automatic measuring device for the penetration depth of a hammer-driven pile includes an annular housing 1 and a photodetector array 3 arranged inside the annular housing 1 and slidably connected to the annular housing 1. The inner side of the annular housing 1 is evenly distributed with an annular LED light source 2 for illuminating the black-and-white scale lines on the pile body. The photodetector array 3 is connected to the input end of a data processing module 4 integrated inside the device, and the output end of the data processing module 4 is connected to a wireless communication module 5. The wireless communication module 5 transmits the measurement data to an external receiving device in real time.

[0024] The photodetector array 3 is in a ring shape. The photodetector array 3 includes a plurality of infrared photodetectors that are equidistantly installed along the inner side direction of the ring and are used to capture the signal changes of light passing through or being blocked by the black and white scale lines. Specifically, the photodetector array 3 contains 36 high-sensitivity infrared photodetectors, which are equidistantly installed along the inner side of the ring-shaped housing 1 and can accurately capture the light changes when passing through the black and white scale lines on the pile body. Each infrared photodetector corresponds to a section of scale line to ensure high-precision measurement. The photodetector array captures the changes of the black and white scale lines on the pile body, converts the optical signal into an electrical signal, and realizes the precise positioning of the pile body movement.

[0025] The photodetector array 3 is slidably adjusted through a calibration mechanism 6 arranged on the ring-shaped housing 1. The calibration mechanism 6 includes a slide bar 601 and a toggle block 602. One end of the slide bar 601 is connected to the photodetector array 3, and the other end of the slide bar 601 is connected to the toggle block 602. Four groups of calibration mechanisms 6 are symmetrically arranged along the circumferential direction of the ring-shaped housing 1, and a chute 101 is opened on the ring-shaped housing 1 corresponding to each group of calibration mechanisms 6. The calibration mechanism can be adjusted to ensure that the sensor accurately aligns with the starting point of the pile body scale, ensuring the accuracy of the initial measurement position.

[0026] The ring-shaped housing 1 is made of lightweight aluminum alloy material, and the surface of the housing is anodized to enhance its weather resistance.

[0027] In a specific embodiment, the ring-shaped LED light source 2 is composed of 60 high-brightness white LED lamp beads, which are evenly distributed on the inner side of the ring-shaped housing 1 and are driven by a constant current power supply to ensure the stable brightness of the light source and reduce the measurement error caused by voltage fluctuation. The LED light source provides uniform and stable illumination to ensure that the scale lines can be clearly identified under different lighting conditions.

[0028] The data processing module 4 uses an embedded microprocessor and integrates a customized algorithm to quickly analyze the signals received by the photodetector, calculate the number of black dots passed, achieve accurate counting of the number of black dots, accurately calculate the number of black dots passing through the sensor within a specific time interval, and convert it into the penetration depth according to the preset unit length, and then deduce the penetration depth of the pile body. This unit also includes a non-volatile memory for storing measurement history records and calibration parameters.

[0029] The wireless communication module 5 supports at least one wireless communication protocol, including Bluetooth or Wi-Fi, ensuring stable and reliable data transmission. The measurement results can be immediately transmitted to the mobile devices of construction management personnel or the central control system, realizing real-time monitoring and remote management of data, and greatly improving construction efficiency. Specifically, the wireless communication module 5 adopts Bluetooth 5.0 technology to achieve low-power and high-speed wireless connection with smartphones or tablets, and transmits measurement data in real time. The external receiving device is a construction monitoring system or an operator's handheld device.

[0030] On the lower part of the outer side of the annular housing 1, there is a fixed plate 7 with openings, which is used to be fixed to the ground through anchor bolts.

[0031] The operation process of the present utility model:

[0032] a. The precast pipe pile to be measured is hoisted into the measuring device. The measuring device is fixed to the ground through the fixed plate 7, and the top of the photodetector is aligned with the lowest end of the scale line on the pile body by using the calibration mechanism 6.

[0033] b. Turn on the device, and the annular LED light source 2 lights up, evenly irradiating the scale line on the pile body.

[0034] c. As the pile is driven deeper, the black and white scale lines on the pile body pass through the photodetector array 3 in sequence, generating corresponding photoelectric signals.

[0035] d. The data processing module 4 receives and analyzes these signals in real time, calculates the depth increment corresponding to each section of the scale through a preset algorithm, and accumulates to obtain the total penetration depth.

[0036] e. The calculation result is sent to the construction monitoring system or the operator's handheld device through the wireless communication module 5 to display the real-time depth information.

[0037] This device is designed specifically for hammer-driven piles, directly fitting the pile body. By using the cooperation of the black and white scale lines and the optical sensor, it realizes direct and accurate measurement of the penetration depth, without being affected by liquid fluctuations or medium transmission problems.

[0038] Through the detailed description of the above embodiments, the optical automatic measuring device for the penetration depth of hammer-driven piles of the present utility model demonstrates its effectiveness and convenience in practical applications. It not only improves the accuracy and real-time performance of measurement, but also simplifies the operation process, reduces the dependence on professional skills, thus significantly improving efficiency and safety during the construction process. In addition, its modular and adjustable design enables the device to adapt to various construction scenarios and pile bodies, having wide applicability and promotion value.
