Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically to a miniature electronic prism for a total station. Background Technology

[0002] In the field of tunnel construction, engineering monitoring is a crucial link in ensuring construction safety, guaranteeing project quality, and optimizing construction processes. Real-time monitoring of parameters such as deformation and displacement in key tunnel areas is of paramount importance. Currently, a common monitoring method involves deploying prism points in these key areas and using a total station to precisely measure the prisms, thereby obtaining information on geometric changes in these critical areas.

[0003] However, in actual tunnel construction, the placement of prism points often faces numerous challenges. On the one hand, due to the relatively limited tunnel space, the placement areas in critical areas are relatively concentrated, or from the perspective of the total station, the distribution of prism points is too narrow. In such cases, when the total station attempts to lock onto the prism, it is affected by spatial limitations and limited viewing angles, making it difficult to accurately and stably capture the prism signal, and thus unable to achieve precise measurements.

[0004] The current common practice is to assign professional personnel to perform manual measurements. While manual measurements can obtain data to some extent, they are inefficient and require a lot of manpower and time. In the time-sensitive and demanding environment of tunnel construction, this will undoubtedly increase construction costs and schedule pressure. Furthermore, manual measurements cannot achieve real-time and continuous monitoring; they can only obtain data at discrete time points, making it difficult to comprehensively and accurately reflect the dynamic changes of key areas of the tunnel during construction. This fails to meet the needs of modern tunnel construction for automated and intelligent monitoring.

[0005] Therefore, in response to the above problems, the applicant needs to design a miniature electronic prism for total stations to solve the problems. Utility Model Content

[0006] The purpose of this invention is to provide a miniature electronic prism for total stations to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a miniature electronic prism for a total station, comprising a support plate, on which a connecting rod is fixedly mounted. A mounting bracket is fixedly mounted at the end of the connecting rod furthest from the support plate, and a conical prism is disposed inside the mounting bracket.

[0008] It also includes: a shielding mechanism for shielding a cone prism, wherein the shielding mechanism includes a micro motor, the output end of the micro motor is provided with an extension rod, and a rotating rod is fixedly provided at the end of the extension rod away from the micro motor, a shielding plate is fixedly provided on the rotating rod, and the shielding plate is used to shield the cone prism, and a support frame is fixedly provided below the micro motor, and the support frame is fixedly connected to the support plate.

[0009] A support mechanism is located below the support plate, and the support mechanism is used to adjust the height of the cone prism.

[0010] Furthermore, a reinforcing frame is fixedly installed on the support frame, and the reinforcing frame is fixedly connected to the mounting frame.

[0011] Furthermore, a support rod is fixedly installed on the reinforcement frame, and the end of the support rod away from the reinforcement frame is fixedly connected to the micro motor.

[0012] Furthermore, the support mechanism includes a threaded rod fixedly connected to the support plate, and a lifting block is rotatably mounted on the threaded rod. A support leg is hinged to the lifting block, and a support seat is hinged to the end of the support leg away from the lifting block.

[0013] Furthermore, the threaded rod is provided with a threaded sleeve, and a reinforcing arm is hinged to the threaded sleeve. The end of the reinforcing arm away from the threaded sleeve is hinged to a connecting lug, and the connecting lug is fixedly connected to the support leg.

[0014] Furthermore, the micro motor is connected to the total station's main control terminal via a wireless communication module, and the wireless communication module supports at least one of the following communication protocols: WIFI, Bluetooth BLE, and 433MHz, enabling the main control terminal to control the switching of the obstruction mechanism and monitor the prism's status.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This total station uses a miniature electronic prism to effectively solve the problems of signal crosstalk in densely distributed tunnels, uneven ground, and construction vibration interference through intelligent occlusion selection, adaptive terrain leveling, and a rigid anti-vibration structure, thereby improving measurement accuracy and automation efficiency. The specific details are as follows:

[0016] When using the miniature electronic prism in this total station, the main control terminal sends control commands to the miniature motor of the designated prism via a wireless communication module. The miniature motor drives the extension rod and the rotating rod, causing the shielding plate to rotate to either shield or expose the cone prism target surface. When the prism needs to be measured, the shielding plate opens to allow the prism to reflect the signal. After the measurement is completed or when it is necessary to avoid crosstalk from adjacent prisms, the shielding plate closes to block the signal, realizing intelligent prism selection and solving the problem of mis-locking in densely distributed points.

[0017] When using the miniature electronic prism in this total station, the support mechanism drives the lifting block to rise and fall by rotating the threaded rod, which in turn extends or retracts the support legs, precisely adjusting the prism height to adapt to uneven tunnel surfaces. The four-bar system consisting of the threaded sleeve and the reinforcing arm automatically tensions the support legs during the lifting process, suppressing swaying and ensuring that the prism's reference plane is absolutely horizontal. The rigid triangular support formed by the reinforcing frame and the support rod enhances the overall vibration resistance, effectively suppressing slight swaying caused by tunnel construction vibrations or airflow, and ensuring the continuity of total station signal reception and the stability of measurement data.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, this utility model discloses a miniature electronic prism for a total station, comprising a support plate 1, on which a connecting rod 10 is fixedly mounted. A mounting bracket 11 is fixedly mounted at the end of the connecting rod 10 away from the support plate 1, and a conical prism 12 is disposed inside the mounting bracket 11. The conical prism 12 uses an extremely small target surface with a diameter of 12.7 mm. The conical prism 12 is equipped with a QR code on the device body and an NFC near-field communication module, allowing for rapid deployment via a mobile app by scanning the QR code or using NFC. It also includes a device for blocking the cone. The prism 12 has a shielding mechanism 2, which includes a micro motor 23. The output end of the micro motor 23 is provided with an extension rod 22, and a rotating rod 21 is fixedly provided at the end of the extension rod 22 away from the micro motor 23. A shielding plate 20 is fixedly provided on the rotating rod 21, and the shielding plate 20 is used to shield the cone prism 12. A support frame 24 is fixedly provided below the micro motor 23, and the support frame 24 is fixedly connected to the support plate 1. A support mechanism 3 is provided below the support plate 1, and the support mechanism 3 is used to adjust the height of the cone prism 12.

[0026] A reinforcing frame 25 is fixedly installed on the support frame 24, and the reinforcing frame 25 is fixedly connected to the mounting frame 11. The reinforcing frame 25 rigidly connects the mounting frame 11 and the support frame 24, improving the stability of the overall structure. In the narrow space of the tunnel, the equipment is easily affected by construction vibration or airflow disturbance. It can effectively suppress the slight sway of the prism and ensure the continuity of signal reception when the total station locks the prism, thereby avoiding the problem of measurement data drift caused by structural deformation.

[0027] A support rod 26 is fixedly installed on the reinforcement frame 25, and the end of the support rod 26 away from the reinforcement frame 25 is fixedly connected to the micro motor 23. The support rod 26 forms a triangular support structure between the micro motor 23 and the reinforcement frame 25, which further disperses the mechanical stress during motor operation. This not only reduces the interference of motor vibration on the positioning accuracy of the prism, but also enhances the impact resistance of the motor in the humid and dusty tunnel environment, extends the service life of the equipment, and reduces the maintenance needs caused by loose parts.

[0028] The support mechanism 3 includes a threaded rod 30 fixedly connected to the support plate 1, and a lifting block 31 is rotatably mounted on the threaded rod 30. A support leg 32 is hinged to the lifting block 31, and a support seat 33 is hinged to the end of the support leg 32 away from the lifting block 31. The spiral lifting mechanism formed by the threaded rod 30 and the lifting block 31 allows for precise adjustment of the prism height. During tunnel construction, uneven ground or temporary obstacles often exist. This design can quickly adapt to complex terrain and ensure that the prism is always within the optimal observation elevation angle range of the total station.

[0029] A threaded sleeve 34 is provided on the threaded rod 30, and a reinforcing arm 35 is hinged to the threaded sleeve 34. A connecting ear 36 is hinged to the end of the reinforcing arm 35 away from the threaded sleeve 34, and the connecting ear 36 is fixedly connected to the support leg 32. The threaded sleeve 34, in conjunction with the reinforcing arm 35 and the support leg 32, forms a four-bar linkage stabilization system. During the lifting process, the reinforcing arm 35 automatically tensions the support leg 32 to suppress structural swaying during height adjustment. Especially in tunnels with soft soil foundations or sloping rock surfaces, it can prevent the prism from tilting due to uneven force on the support leg 32, ensuring the absolute level of the measurement reference surface.

[0030] The micro motor 23 is connected to the total station's main control terminal via a wireless communication module. The wireless communication module supports at least one of the following communication protocols: WIFI, Bluetooth BLE, and 433MHz. This enables the main control terminal to control the switching of the blocking mechanism 2 and monitor the prism status. The wireless communication module also enables the total station's main control terminal to remotely and intelligently control the blocking mechanism 2. By selectively opening and closing the blocking plates 20 of specific prisms, the main control system can actively avoid signal crosstalk from neighboring prisms, solving the problem of total station mis-locking when densely distributed. At the same time, the motor status feedback allows maintenance personnel to monitor the equipment's operating status in real time, reducing the frequency of manual inspections and achieving an automated monitoring closed loop.

[0031] Working principle: When using the miniature electronic prism for this total station, the total station's main control terminal sends control commands to the miniature motor 23 of the designated prism via the wireless communication module. The miniature motor 23 drives the extension rod 22 and the rotating rod 21, causing the shielding plate 20 to rotate to either shield or expose the target surface of the cone prism 12. When the prism needs to be measured, the shielding plate 20 opens to allow the prism to reflect the signal. After the measurement is completed or when it is necessary to avoid crosstalk from adjacent prisms, the shielding plate 20 closes to block the signal, realizing intelligent prism selection and solving the problem of mis-locking in densely packed points. At the same time, the support mechanism 3 drives the lifting block 3 through the rotating threaded rod 30. 1. Lifting and lowering, with the linkage support leg 32 extending or retracting, precisely adjusts the prism height to adapt to uneven tunnel surfaces; the four-bar system consisting of threaded sleeve 34 and reinforcing arm 35 automatically tensions the support leg 32 during lifting and lowering, suppressing swaying and ensuring the prism reference plane is absolutely horizontal. At the same time, the rigid triangular support formed by the reinforcing frame 25 and support rod 26 improves the overall vibration resistance, effectively suppressing slight swaying caused by tunnel construction vibration or airflow, ensuring the continuity of total station signal reception and the stability of measurement data. The entire process achieves remote control, automatic interference avoidance, terrain adaptation, and resistance to environmental interference, achieving efficient closed-loop monitoring.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
