Description

Technical Field

[0001] This utility model relates to the field of nuclear power, and in particular to a ranging device. Background Technology

[0002] Accurate distance measurement is crucial for ensuring the precision of equipment installation, pipeline laying, and the positioning of other critical components during the construction, maintenance, and overhaul of nuclear power plants. Traditional distance measurement methods mainly include tape measures, measuring tapes, and laser rangefinders, but these methods face numerous challenges and limitations when applied in confined spaces.

[0003] For example, in curved pipes or extremely narrow passages, measuring tapes and measuring rods cannot be fully straightened, resulting in inaccurate measurement data. Secondly, due to their large size, laser rangefinders are very inconvenient to operate in confined spaces. Measuring personnel cannot easily extend their arms to operate them, and due to space limitations, the angle and position of the rangefinder cannot be precisely adjusted, preventing the laser measurement from being optimally aimed at the target, thus affecting the accuracy of the measurement data. Therefore, there are areas for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a ranging device to improve the accuracy of measurement data.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1 This utility model provides a distance measuring device that can measure the distance to an object 70 in a curved pipe or narrow passage. The distance measuring device may include a base 10, a display unit 20, a linkage structure 30, a distance measuring probe 40, an angle level 50, a processing unit, a power supply unit, and a handle, etc.

[0038] In one embodiment, the display unit 20 can be used to display the detected distance. The display unit 20 can be designed to be mounted on the base 10, ensuring its stability and fixation within the overall device structure. The display unit 20 and the base 10 can be connected by one of the following methods: snap-fit ​​60, structural adhesive, or bolt fasteners. Snap-fit ​​60 refers to quick connection and separation via structural pins or fasteners. Structural adhesive refers to fixing the display unit 20 to the base 10 using adhesive. Bolt fasteners refer to mechanical connection using bolts and nuts. The display unit 20 can be a digital tube RS485. Digital tubes can be used for numerical display in various electronic devices.

[0039] In one embodiment, the linkage structure 30 may consist of multiple components, allowing for variations in the structure's length, i.e., it can be extended or shortened. The linkage structure 30 may include a fixed end and a movable end. The fixed end may be mounted on the base 10 and typically remains stationary, serving as a base or support point for the entire linkage structure. The movable end can move and extend / retract relative to the fixed end, causing changes in the length of the linkage structure 30. When the linkage structure 30 is in its retracted state, i.e., with all parts retracted, the overall length of the linkage structure 30 can be less than 0.6 meters. In the retracted state, the entire ranging device is easy to carry or suitable for situations requiring a shorter length. When the linkage structure 30 is in its extended state, i.e., with the movable end fully extended, the length of the linkage structure can exceed 1.35 meters. In the extended state, the linkage structure 30 provides greater extension capacity, suitable for situations requiring a longer length.

[0040] In one embodiment, the linkage structure 30 may consist of at least two sleeves (or tubes) arranged concentrically. Adjacent sleeves can nest into each other, i.e., one sleeve can slide into another to achieve telescoping. Each sleeve can slide relative to the others along its axial direction (i.e., along the length of the linkage structure), thereby enabling adjustment of the length of the entire linkage structure 30, i.e., telescoping operation. Threads are provided at the joint of adjacent sleeves, providing additional mechanical connection strength, allowing for more precise length adjustment and stable fixation in the telescoping position. The innermost sleeve can be the movable end, the freely movable portion of the sleeve, through which the telescoping of the linkage structure 30 is achieved. The outermost sleeve is the fixed end, which can be connected to the base 10 for support. The terms "innermost" and "outermost" refer to different sleeves.

[0041] In one embodiment, the linkage structure 30 may consist of at least two connecting rods. A connecting rod is a rigid strip or bar that constitutes the linkage portion. Adjacent connecting rods are connected by a hinge. The hinged connection allows for a certain degree of rotation or movement between the two connecting rods, enabling the structure to be adjusted in multiple directions. Adjacent connecting rods can be connected by a locking device. The locking device includes a connecting shaft and a locking bolt. The locking device is responsible for fixing the connecting rods in the desired position. Specifically, the connecting shaft can be located at the hinge of the two connecting rods, acting as the axis of rotation. The locking bolt can be threaded to one end of the connecting shaft, and after adjustment to the desired position, tightening the bolt locks the angle or position between the two connecting rods. The outermost connecting rod can be the movable end, and the innermost connecting rod can be the fixed end.

[0042] In one embodiment, the ranging probe 40 can be fixed to the movable end of the linkage structure 30. Since the movable end is a freely adjustable and positionable part of the linkage structure, the position and angle of the ranging probe 40 can be flexibly changed to adapt to different measurement needs. The ranging probe 40 can be used to measure the distance between the object being measured and the probe. The specific model of the ranging probe 40 is BGL-FM50PM-485.

[0043] Please see Figure 2In one embodiment, the ranging probe 40 and the movable end can be connected by one of the following methods: snap-fit ​​60, structural adhesive, or bolt fasteners. The connection via snap-fit ​​60 is described as an example. The snap-fit ​​60 may include at least one set of lugs 61 and slots 62. Lugs 61 and slots 62 within the same set can be matched. Lugs 61 and slots 62 from different sets can be symmetrically arranged between the ranging probe 40 and the movable end. The lugs 61 can be fixed to the bottom of the ranging probe 40 or the movable end. The slots 62 correspond to the lugs 61 and are used to accommodate the lugs 61, thereby achieving a secure snap-fit. When the lugs 61 are fixed to the bottom of the ranging probe 40, the movable end needs to have a slot 62 that matches the lugs 61; that is, a groove needs to be reserved in the movable end to facilitate the insertion and fixation of the lugs 61. When the lugs 61 are fixed to the movable end, the bottom of the ranging probe 40 needs to have a corresponding slot 62.

[0044] In one embodiment, the angle level 50 can be fixedly mounted on the base 10. The angle level 50 and the base 10 can be connected by one of the following methods: snap-fit ​​connector 60, structural adhesive, or bolt fasteners. The angle level 50 can be a model such as Jingyan Electronics DXL360s.

[0045] In one embodiment, the number of angle level instruments 50 can be at least one. The base 10 can be rectangular in shape. In this case, when there are two angle level instruments 50, the angle level instruments 50 can be installed on the base 10 in two different directions. For example, one angle level instrument 50 can be fixed on the side parallel to the horizontal plane, and the other angle level instrument 50 can be fixed on the side perpendicular to the horizontal plane, thereby measuring and adjusting the horizontal state of the linkage structure 30.

[0046] Please see Figure 3 In one embodiment, the angle level 50 can be used to detect the angle between the connecting rod structure 30 and the horizontal plane. By obtaining this angle, appropriate adjustments can be made. For example, if the angle between the straight section of the bend 80 and the ground 90 is A, the angle level 50 can be used to adjust the angle between the connecting rod structure 30 and the ground 90 to 90°-A, thereby adjusting the connecting rod structure 30 to a position perpendicular to the straight section, so that its angle with the ground 90 is exactly 90°. This adjustment method ensures a precise relative perpendicularity between the connecting rod structure 30 and the connected straight section, thereby enabling accurate measurement of the object 70 within the straight section.

[0047] In one embodiment, the processing unit can be fixed inside the base 10 to protect it from external environmental influences such as dust and moisture. The processing unit can receive signals from the ranging probe 40 and process these signals to calculate the distance to the measured object 70. The processing unit can be an STC12C5A60S2 microcontroller.

[0048] In one embodiment, the power supply unit may also be fixed within the base 10. The power supply unit may be electrically connected to the processing unit, display unit 20, and ranging probe 40, etc., to supply power to these components.

[0049] In one embodiment, a handle may also be provided on one side of the base 10. The handle is connected to the base 10 by one of the following methods: snap-fit, structural adhesive, or bolt fastener. The operator can perform the measurement by gripping the handle.

[0050] As can be seen, in the above scheme, the linkage structure can replace the arm reaching into confined spaces, thus avoiding human error and reducing the need for personnel to personally enter small or dangerous spaces. The small size of the ranging probe allows for easy entry into narrow spaces for measurement, overcoming the limitations of traditional tools in space-constrained conditions. Using an angle level, the measuring angle of the laser from the ranging probe can be adjusted for precise alignment with the object being measured. This angle adjustment improves measurement accuracy, especially ensuring that the laser is perpendicular to the object, thus enhancing measurement precision. Whether the straight pipe section in the pipeline is horizontal or forms an angle with the ground, it can be appropriately adjusted using an angle level to adapt to different angle requirements.

The embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
