Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe testing technology, specifically to a rapid screening instrument for cable protection pipes. Background Technology

[0002] Cable protection pipes are crucial components in power systems used to protect underground cables. Their primary function is to prevent cables from suffering mechanical damage, chemical corrosion, and environmental influences during laying and operation. During the production of cable protection pipes, strict control of the pipe's inner diameter is essential to ensure successful cable installation and effective protection. Factors such as extrusion pressure, mold wear, and cooling shrinkage can cause deviations in the inner diameter of cable protection pipes in different sections. Failure to adjust these deviations promptly can severely impact the quality of the entire batch. Therefore, inspecting the inner diameter of cable protection pipes to maintain overall consistency is a critical step in determining whether production is up to standard.

[0003] Currently, the industry largely relies on manual operation for inspecting the inner diameter of cable protection pipes, typically using tools such as calipers, inside gauges, or plug gauges for point-by-point measurements. This method not only requires a large workforce and is labor-intensive, but it is also slow and inefficient, making it difficult to achieve rapid screening in continuous, high-volume production processes. Furthermore, manual inspection is susceptible to errors due to operator experience and measurement techniques, resulting in low repeatability and reliability of the results, failing to meet the demands of modern production lines for real-time quality monitoring and highly efficient automated inspection.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a rapid screening device for cable protection pipes to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A rapid screening device for cable protection pipes includes a connecting plate with positioning rings connected to both ends of the connecting plate. Two pairs of adjusting screws are threaded to each side of the surface of the positioning rings. One end of the adjusting screw has a shrinkage groove, and a positioning rod is slidably installed inside the shrinkage groove. A detection block is connected to the end of the positioning rod. A laser emitter is installed on the surface of the detection block on one positioning ring, and a photoelectric sensor is installed on the surface of the detection block on the other positioning ring. A rolling wheel is rotatably installed on one end of the detection block.

[0008] Furthermore, in order to enable the detection block to move according to the inner diameter of the cable protection pipe, a telescopic spring is connected between the detection block and the adjusting screw, and a hub motor is installed inside the rolling wheel.

[0009] Furthermore, in order to clamp and limit the rotation of the rolling wheel after adjustment, a positioning plate is connected to one side of the detection block, and a clamping bolt is threaded onto the surface of the positioning plate. A limit ring is rotatably installed at the end of the clamping bolt.

[0010] Furthermore, in order to provide power to the various electrical components within the device, a storage battery is installed on one side of the inside of the connecting plate.

[0011] Furthermore, in order to control the various electrical components within the device, a support plate is installed on one side of the connecting plate, a microcontroller is installed on the surface of the support plate, and a multi-control switch is installed on one side of the microcontroller.

[0012] Furthermore, in order to enable the device to issue an alarm when it detects cable protection pipes with different inner diameters, an alarm is installed on one side of the connecting plate.

[0013] Furthermore, to facilitate the adjustment of the adjusting screw, a turning block is connected to one end of the adjusting screw.

[0014] The beneficial effects of this invention are as follows: By adjusting the rotation of the screw on the positioning ring, the device can adapt to cable protection pipes of different sizes. After placing the device on the inner wall of the cable protection pipe to be screened, the hub motor drives the rolling wheel to move the entire device inside the protection pipe. This allows the laser emitter and photoelectric sensor on the two positioning rings to respond in real time to changes in the inner diameter of the protection pipe, thus achieving automated screening of the inner diameter of the cable protection pipe. This significantly improves the detection speed, avoids the time-consuming process of traditional manual point-by-point measurement, meets the rapid screening needs in large-scale production, reduces manpower input and labor intensity, avoids measurement errors caused by human factors, and improves the consistency and reliability of the detection.

[0023] 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.

[0024] According to an embodiment of the present invention, a rapid screening instrument for cable protection pipes is provided.

[0025] Example 1:

[0026] like Figures 1-5As shown, a rapid screening device for cable protection pipes according to an embodiment of this utility model includes four metal connecting plates 1. A pair of positioning rings 2 are connected to both ends of each connecting plate 1. Two pairs of adjusting screws 3 are threaded onto each side of the surface of the positioning rings 2. The adjusting screws 3 are distributed around the positioning rings 2 at a 90° angle. By turning the adjusting screws 3, the device can adapt to cable protection pipes of different sizes. A shrinkage groove 4 is opened at one end of the adjusting screw 3 outside the positioning rings 2. A positioning rod 5 is slidably installed inside the shrinkage groove 4, enabling extension and contraction when the inner diameter of the cable protection pipe changes. A detection block 6 is connected to the end of the positioning rod 5. A laser emitter 7 is installed on the surface of each detection block 6 on one of the positioning rings 2 to emit a light source during detection. A photoelectric sensor 8 is installed on the surface of each detection block 6 on the other positioning ring 2 to receive the light emitted by the laser emitter 7. A rolling wheel 9 is rotatably installed at one end of the detection block 6 for the entire device to move inside the cable protection pipe to be inspected.

[0027] like Figures 1-5 As shown, a telescopic spring 10 is connected between the detection block 6 and the adjusting screw 3. Through its own elasticity, the positioning rod 5 can extend and retract within the contraction groove 4. A hub motor 11 is installed inside the rolling wheel 9 to provide power for its rotation. A positioning plate 12 is connected to one side of the detection block 6. A clamping bolt 13 is threaded onto the surface of the positioning plate 12. A limit ring 14 is rotatably installed at the end of the clamping bolt 13. When the rolling wheel 9 is adjusted, tightening the clamping bolt 13 clamps and limits the adjusted rolling wheel 9, preventing it from continuing to rotate on the detection block 6. A storage battery 15 is installed inside one side of the connecting plate 1. There are two 15s, which are used to provide power to the various electrical components in the device. A support plate 16 is installed on one side of the inside of the connecting plate 1. A microcontroller 17 is installed on the surface of the support plate 16. A multi-control switch 18 is installed on one side of the microcontroller 17 to control the switching of the various electrical components in the device. An alarm 19 is installed on one side of the inside of the connecting plate 1. When the photoelectric sensor 8 does not detect the light source emitted by the laser emitter 7, the microcontroller 17 can quickly control the alarm 19 to sound an alarm, thereby reminding the staff that the inner diameter of the pipe at the inspection point has changed. One end of the adjusting screw 3 is connected to a turning block 20 for easy turning and rotating of the adjusting screw 3.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the entire device is placed inside the cable protection pipe to be tested. By turning each adjusting screw 3, each rolling wheel 9 is made to fit tightly against the inner wall of the pipe, and the distance between two corresponding rolling wheels 9 is the same as the inner diameter of the pipe. At this time, each detection block 6 on the two positioning rings 2 corresponds to the laser emitter 7 and emits light to the photoelectric sensor 8. After starting the hub motor 11, each rolling wheel 9 can drive the entire device to move inside the cable protection pipe. When the inner diameter of the protection pipe changes, the positioning rod 5 can extend or retract with the change of pipe diameter through the telescopic spring 10. At this time, the detection block 6 on the positioning ring 2 that enters the pipe first moves with the positioning rod 5. After the photoelectric sensor 8 on its surface can no longer receive the light emitted by the laser generator, the microcontroller 17 quickly controls the alarm 19 to sound an alarm, reminding the staff that the inner diameter of the pipe has changed at this point, thereby realizing the automated and rapid screening of the inner diameter of the cable protection pipe.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
