DETAILED DESCRIPTION

[0029] In order to make the technical personnel in the art better understand the technical scheme of the present application, the following will be further introduced in detail with reference to the drawings.

[0030] As shown in Figures 1 to 5 The present application provides a kind of engineering measurement wire releasing device, including wire releasing box 1, ink box 2, winding rod 5 and connecting block 7.

[0031] The wire feeding box 1 is injection molded from ABS engineering plastic, making it lightweight and durable. An ink cartridge 2, made of transparent PP material, is fixedly installed at the bottom inside the wire feeding box 1, allowing for easy observation of the remaining ink level. The ink cartridge 2 contains specialized engineering ink, which is fast-drying, water-resistant, and has vibrant colors.

[0032] Inside the ink cartridge 2, a rotating roller 3 is rotatably connected via a bearing. The rotating roller 3 is made of stainless steel, and an ink-soaked sponge sleeve 4 is fixedly fitted to its outer end. The ink-soaked sponge sleeve 4 is made of highly absorbent sponge material and is completely immersed in the ink, which can fully absorb and retain the ink.

[0033] The winding rod 5 is rotatably connected inside the pay-off box 1 via a bearing, with one end extending to the front of the pay-off box 1. A measuring wire 6 is wound around the outer end of the winding rod 5. The measuring wire 6 is made of high-strength nylon thread with a waterproof surface and a diameter of 1.5mm. A connecting hole 13 is provided on one side of the pay-off box 1, with a ceramic wire guard ring embedded within it to prevent wear on the measuring wire 6. One end of the measuring wire 6 passes through the connecting hole 13 and extends to the side of the pay-off box 1, fitting snugly against the outer end of the ink-soaked cotton sleeve 4, allowing it to be evenly coated with ink as it passes through.

[0034] The connecting block 7 is made of aluminum alloy and is fixedly connected to one end of the measuring line 6 using a special clamp. A laser emitter 8 is fixedly installed on one side of the cable box 1. The laser emitter 8 uses a 650nm red laser module with a power of <5mW, meeting Class II laser safety standards. A laser receiver 9, corresponding to the laser emitter 8, is fixedly installed on the inner bottom of the connecting block 7. The laser receiver 9 uses a photoresistor sensor (such as GL5528).

[0035] A controller 10 is fixedly mounted on one side of the cable box 1. The controller 10 uses an STM32 series microcontroller, which integrates signal processing and logic control functions. An indicator light 11 is fixedly mounted on the top of the controller 10. The indicator light 11 uses a dual-color LED (red / green). The laser receiver 9 and the indicator light 11 are connected to the input and output terminals of the controller 10 via wires.

[0036] The vertical distance between the laser emitter 8 and the measuring line 6 is the same as the vertical distance between the laser receiver 9 and one end of the measuring line 6, ensuring that the laser beam can accurately illuminate the receiver.

[0037] The wire feeding box 1 is rotatably connected to a wire pressing rotating rod 12. The surface of the wire pressing rotating rod 12 is covered with a rubber layer and is located at the top of the measuring line 6, which is close to the outer end of the ink-impregnated cotton sleeve 4, to ensure that the measuring line and the ink-impregnated cotton sleeve are in full contact.

[0038] Two stainless steel fixing rods 14 are fixed on one side of the wire box 1. A guide ring 15 is fixed at one end of the two fixing rods 14. A ceramic guide ring is embedded in the guide ring 15. One end of the measuring wire 6 passes through the inside of the guide ring 15, which serves to guide and prevent wire wear.

[0039] A rotating plate 16, which is a circular plastic plate, is fixedly attached to one end of the winding rod 5. A limiting rod 17 is provided on the outer edge of the rotating plate 16. Multiple limiting grooves 18 are provided at the front end of the wire release box 1, and the multiple limiting grooves 18 are arranged in a ring on the outer side of one end of the winding rod 5. One end of the limiting rod 17 passes through the rotating plate 16 and extends into one of the limiting grooves 18. A connecting plate 19 is fixedly attached to the other end of the limiting rod 17. A spring 20 is sleeved on the outer end of the limiting rod 17, and the two ends of the spring 20 are fixedly connected to the inner side of the connecting plate 19 and the outer side of the rotating plate 16, respectively. A handle 21 is rotatably connected to the outer side of the connecting plate 19 for easy manual wire winding and unwinding operations.

[0040] The top of the pay-off box 1 is provided with a cover 22, which is connected to the pay-off box 1 by a hinge. The bottom end of the cover 22 extends into the interior of the pay-off box 1. A silicone sealing ring 23 is fixedly provided on the inner wall of the top opening of the pay-off box 1. The bottom end of the cover 22 is located inside the sealing ring 23 to ensure good sealing and prevent ink evaporation.

[0041] The working principle of this utility model is as follows: In use, open the cover 22 and inject an appropriate amount of engineering ink into the ink cartridge 2. The ink-soaked cotton sleeve 4 fully absorbs the ink. Pull the measuring line 6 out from the winding rod 5. As the measuring line 6 passes through the ink-soaked cotton sleeve 4, it is evenly coated with ink. By pulling the connecting block 7, the measuring line 6 is extended to the position where the line needs to be drawn.

[0042] Turn on the laser emitter 8 switch, and the laser beam will be directed towards the laser receiver 9. When the operator moves the connecting block 7, they can observe the status of the indicator light 11 to determine if the measurement line remains straight. When the laser receiver 9 receives the laser signal normally, the controller 10 will control the indicator light 11 to display green, indicating that the measurement line is straight. When the measurement line deviates from the straight line, the laser receiver 9 will not receive the laser signal, and the controller 10 will control the indicator light 11 to display red, prompting the operator to adjust the direction.

[0043] After the wire is unloaded, the winding rod 5 is wound up by rotating the handle 21. The cooperation of the limiting rod 17 and the limiting groove 18 can fix the position of the winding rod and prevent it from rotating automatically.

[0044] This invention, through the cooperation of a laser emitter, a laser receiver, and an indicator light, achieves real-time straightness monitoring during the laying-out process, greatly improving the accuracy and precision of the laying-out and avoiding deviations caused by manual judgment. Specifically, this embodiment solves the problem in existing engineering surveying and laying-out devices where, during actual use, the person laying out the line pulls it towards the area to be marked, and the straightness of the line is judged manually. This manual judgment is prone to causing large deviations in the laying-out, making it impossible to guarantee the straightness of the line and affecting subsequent construction.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
