Description

Technical Field

[0001] This utility model belongs to the field of laser ranging sensor technology, specifically relating to an automated, small, intelligent laser ranging sensor. Background Technology

[0002] In engineering construction, as well as in large-scale buildings and areas prone to geological disasters, displacement changes occur to varying degrees due to various factors. Displacement changes are a crucial parameter in engineering construction and disaster early warning. Some displacement changes are within permissible ranges, while others can lead to compromised engineering quality or even catastrophic accidents. Monitoring displacement changes in large buildings and structures is particularly important. Typical examples include tunnel convergence, foundation pit displacement, changes in unstable rock displacement, and tailings dam dry beach length falling below a certain warning threshold, which can cause accidents, resulting in significant casualties and other social harms.

[0003] In recent years, with the increasing construction of national highways, railways, and high-speed railways, the number of tailings dams approaching 200 meters has been rising, leading to frequent engineering quality accidents. Furthermore, with the service life of these projects, displacement and deformation of tunnels, bridges, and geological disaster-prone areas, as well as the length of dry tailings dam beaches, all change. Monitoring is generally conducted in areas with frequent relative displacement changes. Traditional monitoring methods include manual monitoring using single-unit levels, handheld laser rangefinders, GPS ranging, or automated robots. Automated robot monitoring has high installation requirements and is inconvenient for tunnels and construction sites with relatively harsh environments. Laser ranging is relatively reliable for monitoring large-scale displacements. However, in monitoring displacement changes in engineering construction and geologically hazardous areas, the location and direction of monitoring points need to be adjusted according to the actual situation. Existing laser rangefinder sensors are inconvenient to adjust angles, making it difficult to adjust the monitoring direction and unable to accurately adapt to different monitoring needs, thus reducing the flexibility of monitoring. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automated, small, intelligent laser rangefinder sensor. This sensor aims to partially solve the technical problem in the prior art where the angle adjustment of existing laser rangefinder sensors is inconvenient, leading to operational difficulties when adjusting the monitoring direction, inability to accurately adapt to different monitoring needs, and reduced monitoring flexibility.

[0005] The technical solution of this utility model is: an automated small intelligent laser rangefinder sensor, including a fixed frame and a sensor body. The fixed frame is connected to the sensor body through a connector and is used to adjust the angle of the sensor body.

[0006] The connector includes a back plate and an adjustment assembly. The top of the back of the back plate is rotatably connected to the fixing frame, and both ends of the adjustment assembly are rotatably connected to the back of the fixing frame and the back of the back plate, respectively.

[0007] The adjustment assembly includes a first threaded rod and a second threaded rod, the first threaded rod and the second threaded rod have opposite thread directions, and a threaded sleeve is threaded on the outer surface of their opposite ends.

[0008] In some embodiments, a support plate is fixedly connected to the top of the inner sidewall of the fixing frame, and the side of the support plate away from the fixing frame is rotatably connected to the back plate.

[0009] In some embodiments, the mounting bracket is provided with a plurality of mounting holes for fixing the mounting bracket onto the target object.

[0010] In some embodiments, reinforcing plates are fixedly connected to both sides of the inner wall of the fixing frame, and the bottom of the reinforcing plates is fixedly connected to the inner top wall of the fixing frame.

[0011] In some embodiments, the mounting bracket is L-shaped, and the middle part of the mounting bracket is provided with a clearance groove for clearance when the sensor body angle is adjusted.

[0012] In some embodiments, the back plate has multiple fixing holes, and fixing bolts are inserted into the fixing holes. One end of the fixing bolts is threaded onto the sensor body.

[0013] In some embodiments, a through-hole is provided in the middle of the outer surface of the threaded sleeve.

[0014] In some embodiments, the outer surface of the threaded sleeve is provided with anti-slip texture.

[0015] In some embodiments, a first locking nut is threaded onto the outer surface of the first threaded rod, and the bottom of the first locking nut abuts against the top of the threaded sleeve.

[0016] The outer surface of the second threaded rod is threaded with a second locking nut, and the top of the second locking nut abuts against the bottom of the threaded sleeve.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] 1. The connection component allows for flexible adjustment of the sensor body angle, enabling rapid and accurate adjustment of the monitoring direction in engineering construction and geological disaster risk area displacement change monitoring, meeting the needs of different monitoring scenarios and greatly improving the flexibility and adaptability of monitoring.

[0019] 2. Since the threads of the first threaded rod and the second threaded rod are in opposite directions, when the threaded sleeve rotates, the first threaded rod and the second threaded rod will move relative to each other or in opposite directions due to the interaction of the threads. This causes the back plate to rotate at the hinge point between the support plate and the back plate, thereby flexibly adjusting the angle of the sensor body. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] In engineering construction and displacement change monitoring in geological hazard-prone areas, the location and orientation of monitoring points need to be adjusted according to the actual situation. Existing laser rangefinders are inconvenient to adjust in terms of angle, leading to operational difficulties when adjusting the monitoring direction, failing to accurately adapt to different monitoring needs, and reducing monitoring flexibility.

[0034] Due to the inconvenience of angle adjustment, when conducting multi-point monitoring or frequently changing the monitoring direction, a lot of time and effort is required to adjust the sensor angle, which increases the difficulty and time cost of monitoring work. This not only affects the monitoring efficiency, but also causes some important displacement change information to be missed during the adjustment process.

[0035] Inaccurate angles in laser rangefinders can cause the laser beam to deviate from the target, affecting measurement accuracy. In scenarios requiring precise displacement measurement, such as tunnel convergence monitoring, angular deviations can lead to significant errors in the measurement results, failing to accurately reflect the actual displacement and posing potential risks to engineering safety assessments.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments:

[0037] This utility model provides an automated small intelligent laser rangefinder sensor. With the setting of the connector 200, the angle of the sensor body 300 can be flexibly adjusted. In engineering construction and displacement change monitoring in geological disaster-prone areas, it can quickly and accurately adjust the monitoring direction to meet the needs of different monitoring scenarios, and greatly improve the flexibility and adaptability of monitoring.

[0038] Specifically:

[0039] Please see Figure 1-6 An automated, small, intelligent laser rangefinder sensor includes a mounting bracket 100 and a sensor body 300. The mounting bracket 100 is connected to the sensor body 300 via a connector 200 and is used to adjust the angle of the sensor body 300.

[0040] The sensor body 300 is a laser rangefinder sensor with dimensions of 45mm*40mm*78mm. Its hardware output interface is RS485, enabling network measurement. The sensor body 300 is wide-range powered, requiring only DC 8-35V. With a 12V power supply, the sensor's static operating current is 25mA, and the operating current during laser measurement is 30mA. The sensor body 300 supports common data acquisition interfaces such as RS485, CAN, WIFI, ZIGBEE, 4G, and fiber optic.

[0041] The sensor body 300 includes a housing, a phase acquisition unit, a data processing and transmission unit, a laser transceiver unit, and a power module. The housing encapsulates the circuitry and stores the measurement medium. Changes in the measurement medium are reflected by the laser transceiver unit, acquired by the phase acquisition unit, and then the data processing and transmission unit performs internal calculations and transmits the data to the interface output according to a certain protocol to complete the entire measurement process.

[0042] The sensor body is small, easy to seal, and has a certain degree of corrosion resistance; therefore, the outer shell is made of aluminum alloy. The phase acquisition unit consists of a phase calculation chip and a modulation chip. The data processing and transmission unit is a microcontroller. The microcontroller samples data including phase information and temperature sensor readings. After acquisition, it calculates the pressure based on the calibration table and calibration parameters stored in the storage chip. Then, the microcontroller sends the sampled data to the bus according to the agreed protocol via the interface chip. The bus connects to the acquisition terminal, and displacement changes can be monitored according to the agreed protocol.

[0043] The connector 200 includes a back plate 210 and an adjustment assembly 220. The top of the back of the back plate 210 is rotatably connected to the fixing frame 100, and the two ends of the adjustment assembly 220 are rotatably connected to the fixing frame 100 and the back of the back plate 210, respectively.

[0044] The adjustment assembly 220 includes a first threaded rod 221 and a second threaded rod 222. The threads of the first threaded rod 221 and the second threaded rod 222 are in opposite directions, and a threaded sleeve 223 is threaded onto the outer surface of their opposite ends. In engineering construction and displacement change monitoring in geological disaster-prone areas, the position and direction of the monitoring point may change due to actual conditions. This sensor can accurately adjust the monitoring direction to meet the needs of different monitoring scenarios, greatly improving the flexibility and adaptability of monitoring.

[0045] In some embodiments, a support plate 110 is fixedly connected to the top of the inner sidewall of the mounting bracket 100, and the side of the support plate 110 away from the mounting bracket 100 is rotatably connected to the back plate 210. The support plate 110 enables the back plate 210 to rotate flexibly around the hinge point between the support plate 110 and the back plate 210, which facilitates the adjustment of the angle of the sensor body 300.

[0046] In some embodiments, the mounting bracket 100 is provided with a plurality of mounting holes 120 for fixing the mounting bracket 100 onto the target object.

[0047] In some embodiments, reinforcing plates 130 are fixedly connected to both sides of the inner wall of the fixing frame 100, and the bottom of the reinforcing plates 130 is fixedly connected to the inner top wall of the fixing frame 100. The reinforcing plates 130 can enhance the structural strength of the fixing frame 100.

[0048] In some embodiments, the mounting bracket 100 is L-shaped, and the mounting bracket 100 has a clearance groove 140 in the middle for clearance when the sensor body 300 is adjusted.

[0049] In some embodiments, the back plate 210 is provided with a plurality of fixing holes 230, and fixing bolts 240 are inserted into the fixing holes 230. One end of the fixing bolts 240 is threaded to the sensor body 300, which facilitates the installation and fixing of the sensor body 300.

[0050] In some embodiments, a through-hole 224 is provided in the middle of the outer surface of the threaded sleeve 223. During angle adjustment, the operator can use a suitable tool to insert into the through-hole 224 to facilitate the rotation of the threaded sleeve 223.

[0051] In some embodiments, the outer surface of the threaded sleeve 223 is provided with anti-slip texture. When rotating the threaded sleeve 223 to adjust the angle, the anti-slip texture can prevent the hand from slipping, making it easier to rotate the threaded sleeve 223.

[0052] In some embodiments, a first locking nut 225 is threaded onto the outer surface of the first threaded rod 221, with the bottom of the first locking nut 225 abutting against the top of the threaded sleeve 223; a second locking nut 226 is threaded onto the outer surface of the second threaded rod 222, with the top of the second locking nut 226 abutting against the bottom of the threaded sleeve 223. After the sensor body 300 is adjusted to a suitable angle, the first locking nut 225 and the second locking nut 226 are tightened to fix the threaded sleeve 223, ensuring that the sensor body 300 remains stable during monitoring.

[0053] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
