Description

Technical Field

[0001] This utility model belongs to the field of fire protection pipeline inspection, and specifically relates to a fire protection pipeline inspection device. Background Technology

[0002] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials, and to transport fire extinguishing water, gas or other media. Due to special needs, fire protection pipelines have special requirements for thickness and material, and are painted red. They transport fire protection water and generally need to be inspected regularly to ensure the overall sealing of the pipeline.

[0003] Chinese utility model patent CN220354827U discloses an internal pipeline inspection device for building fire protection water supply, belonging to the technical field of building fire protection pipeline inspection equipment. It includes a camera, a turbine, and a fan wheel. The turbine is fixedly connected to the front outer end of the camera, and the fan wheel is fixedly connected to the rear outer end of the camera. The overall density of the camera, turbine, and fan wheel is the same as the density of water. A speed reduction cam is rotatably connected to the rear of the camera. The camera includes a sealed shell, a fixed shaft, and a transparent window. The transparent window is sealed and fixedly connected to the sealed shell. The device is placed inside a fire protection pipeline with a radius more than twice the device's radius. Water is then released from the target location. The device's flow speed is controlled by adjusting the water velocity. When inspecting vertical pipelines, the inspection is performed directly through the camera, turbine, and fan wheel.

[0004] The above design uses a camera, worm gear, and fan wheel to move the device inside the pipeline and capture images of the pipeline's interior, facilitating the inspection of the pipeline's internal sealing. However, during use, external pressure or collisions can cause dents or bulges inside the pipeline. While this may not cause the pipeline to rupture immediately, it poses a certain safety hazard. The camera's spiral movement inside the pipeline in the above design can easily cause omissions, making it impossible to detect these dents and affecting the overall monitoring quality.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a fire pipeline inspection device includes a main body 1, a top connecting block 2, a mating plate 3, and a linkage block 4. The top connecting block 2 is fixedly installed at the top of the main body 1. The mating plates 3 are equidistantly arranged on the outside of the main body 1. The linkage block 4 is arranged at the bottom of the mating plate 3. A moving mechanism 5 is fixedly installed at the end of the mating plate 3. The moving mechanism 5 includes a base frame 51, a rotating rod 52, and a detection wheel 53. The base frame 51 is fixedly installed at the end of the mating plate 3. The rotating rod 52 is rotatably installed inside the base frame 51. The detection wheel 53 is fixedly installed outside the rotating rod 52. A rotating mechanism 6 is fixedly installed on the outside of the main body 1. A monitoring mechanism 7 is arranged at the bottom of the linkage block 4.

[0030] In use, the main body 1 is selected according to the inner diameter of the pipeline to be tested. Then, through the cooperation of the main body 1 and the top connecting block 2, the main body 1 moves along the pipeline. At this time, through the use of the rotating mechanism 6, the mating plate 3 and the moving mechanism 5 are kept in close contact with the inside of the pipeline, which facilitates the subsequent detection of the protruding parts inside the pipeline by the moving mechanism 5. The presence of the rotating rod 52 allows the detection wheel 53 to keep rotating. Then, with the support of the mating plate 3, the detection wheel 53 will move in close contact with the inner wall of the pipeline. When there is a protrusion in the pipeline, the movement trajectory of the detection wheel 53 at the corresponding position will fluctuate. At this time, the monitoring mechanism 7 is automatically triggered to process the detection signal and data, which facilitates the subsequent repair of the pipeline by the user, thereby making the detection effect of the equipment more perfect.

[0031] From the appendix Figure 4 As shown in this embodiment, both the main body 1 and the top connecting block 2 are symmetrically equipped with conveying rollers, and the highest height of the conveying rollers is consistent with the highest height of the detection roller 53. In use, it can be ensured that the detection roller 53 and the conveying roller can always be in close contact with the inside of the pipeline, and while moving along the pipeline, the condition inside the pipeline can be detected.

[0032] From the appendix Figure 4 As shown in this embodiment, a rotating component is fixedly installed at the bottom of the base frame 51. The rotating component is rotatably connected to the linkage block 4. When the angle of the mating plate 3 changes during use, the linkage block 4 can still trigger the internal components of the monitoring mechanism 7 at the bottom through the cooperation of the rotating component.

[0033] From the appendix Figure 5 As shown, in this embodiment, the rotating mechanism 6 includes a fixed ring 61, a rotating groove 62, a rotating frame 63, a torsion spring 64, and a first spring 65. The fixed ring 61 is fixedly installed outside the main body 1. The rotating groove 62 is equidistantly provided inside the fixed ring 61. The rotating frame 63 is rotatably installed inside the rotating groove 62. Torsion springs 64 are symmetrically arranged on both sides of the rotating frame 63. The rotating frame 63 is fixedly connected to the mating plate 3. The first spring 65 is provided at the bottom of the mating plate 3.

[0034] During use, the rotating frame 63 automatically tilts upwards due to the use of the torsion spring 64. The presence of the mating plate 3 and the first spring 65 further enhances the stability of the mating plate 3 when it tilts upwards, allowing the detection wheel 53 at the end of the mating plate 3 to always be in close contact with the inside of the pipeline, which facilitates the operation and detection of the moving mechanism 5.

[0035] From the appendix Figure 5 As shown, in this embodiment, a limit bracket is fixedly installed on the surface of the fixing ring 61 at the top of the rotating groove 62. During use, it is used to control the maximum angle of the mating plate 3 as a whole, so as to prevent the overall angle of the mating plate 3 from deviating too much and affecting the accuracy of the equipment detection.

[0036] From the appendix Figure 6 As shown, in this embodiment, the monitoring mechanism 7 includes a lifting rod 71, an outer cylinder 72, an infrared rangefinder 73, and a ranging end 74. The lifting rod 71 is rotatably mounted on the bottom end of the linkage block 4. The outer cylinder 72 is fixedly mounted on the surface of the main body 1. The ranging end 74 is fixedly mounted on the bottom end of the lifting rod 71. The infrared rangefinder 73 is fixedly mounted inside the outer cylinder 72. The infrared rangefinder 73 and the ranging end 74 are in contact.

[0037] During use, with the cooperation of the lifting rod 71 and the linkage block 4, when the detection wheel 53 moves along the protruding part, the lifting rod 71 will automatically move downward. At this time, the distance between the measuring end 74 and the infrared rangefinder 73 is reduced. Through the use of the infrared rangefinder 73, the change data of the distance between the infrared rangefinder 73 and the measuring end 74 is recorded and monitored for subsequent observation by the user.

[0038] From the appendix Figure 6As shown in this embodiment, the overall length of the lifting rod 71 is linked to the threshold value of the protrusion to be detected. In use, different lengths of the lifting rod 71 can be replaced according to the different threshold values ​​of the protrusion height inside the pipeline, which facilitates the accuracy of detection and can also filter out some reasonable movements.

[0039] From the appendix Figure 1 As shown in this embodiment, a conical pushing block is fixedly installed on the top of the top connecting block 2, which facilitates the stable movement of the main body of the equipment inside the pipeline during use. The conical pushing block can push away the impurities remaining inside the pipeline.

[0040] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
