Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically to a leak-proof detection pipeline for petrochemical applications. Background Technology

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons that occur naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but conventionally, "petroleum" is still used to define "crude oil." Petrochemicals transport petroleum through pipelines, and pipeline ruptures can lead to leaks. However, it is difficult to locate and repair leaks, posing safety hazards. Therefore, a leak-proof detection pipeline for petrochemicals is proposed to address these issues. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a leak-proof detection pipeline for petrochemical applications, and to provide the following technical solution: a leak-proof detection pipeline for petrochemical applications, comprising a connecting pipe, wherein the connecting pipe has a middle cavity with openings on the left and right sides, and a fixing rod is fixedly connected to the front and rear side walls of the middle cavity respectively, and the two fixing rods are fixedly connected to the same detection shell;

[0004] The detection housing is provided with a detection cavity, and a mounting plate is fixedly connected to the detection cavity. A speed detector is fixedly installed on the mounting plate. A detection shaft is connected to each of the left and right ends of the speed detector. A movable shaft is slidably connected to the detection shaft through a locking block. The movable shaft passes through the detection cavity and enters the intermediate cavity. A rotating wheel is fixedly connected to the movable shaft. Several rotating blades are fixedly connected to the side wall of the rotating wheel.

[0005] As a preferred embodiment of this invention, both the rotating wheel and the rotating blade have rounded corners.

[0006] As a preferred embodiment of this utility model, the mounting plate is fixedly provided with a telescopic device, and a telescopic rod is poweredly connected to each of the left and right ends of the telescopic device, and the telescopic rod is fixedly connected to a fixing plate.

[0007] In a preferred embodiment of this invention, a movable plate is fixedly connected to the lower end face of the telescopic rod, and the movable plate is rotatably connected to the movable shaft.

[0008] As a preferred embodiment of this invention, each of the left and right ends of the connecting pipe is threaded with a connecting ring, which can be snapped into the petrochemical pipeline.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model, through the setting of a connecting ring, can be connected to a petrochemical pipeline to detect leaks in the petrochemical pipeline. Through the setting of a rotating blade, it can drive the rotating wheel to rotate when the petrochemical pipeline is transporting materials. Then, by the difference in rotation speed of the two rotating wheels, the flow velocity difference of the transported materials in the pipeline can be obtained, thereby determining whether there is a leak in the petrochemical pipeline.

[0011] 2. This utility model, through the installation of an expansion joint, can drive two telescopic rods to extend and retract, thereby causing two rotating wheels to move away from and closer to each other. This allows for the initial large-scale confirmation of whether there is a leak in the petrochemical pipeline during use, and then the movement of the two rotating wheels to confirm the specific extent of the leak, facilitating maintenance and repair.

Detailed Implementation

[0019] 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.

[0020] Example 1:

[0021] like Figures 1 to 6 As shown, the present invention provides a leak-proof detection pipeline for petrochemicals, including a connecting pipe 101. The connecting pipe 101 has a middle cavity 102 with openings on the left and right sides. A fixing rod 104 is fixedly connected to the front and rear side walls of the middle cavity 102 respectively. The two fixing rods 104 are fixedly connected to the same detection shell 105.

[0022] The detection housing 105 has a detection cavity 106, and a mounting plate 107 is fixedly connected to the detection cavity 106. A speed detector 108 is fixedly mounted on the mounting plate 107. A detection shaft 109 is connected to each of the left and right ends of the speed detector 108. A moving shaft 115 is slidably connected to the detection shaft 109 through a locking block. The moving shaft 115 passes through the detection cavity 106 and enters the intermediate cavity 102. A rotating wheel 116 is fixedly connected to the moving shaft 115. Several rotating blades 117 are fixedly connected to the side wall of the rotating wheel 116. When transporting petroleum or other materials in the petrochemical industry, the rotating blades 117 are driven to rotate, which in turn drives the rotating wheel 116, the moving shaft 115, and the detection shaft 109 to rotate. The speed is then detected by the speed detector 108. The difference in speed between the two rotating wheels 116 indicates whether the pipeline is leaking.

[0023] Both the rotating wheel 116 and the rotating blade 117 have rounded corners to facilitate the flow of petrochemical petroleum or other transported goods.

[0024] Example 2:

[0025] Please see Figures 1-6 In order to adjust the distance between the two rotating wheels 116 to measure the leakage of the pipeline at different distances, an expansion joint 111, an expansion rod 112, a fixed plate 113 and a movable plate 114 are provided.

[0026] The mounting plate 107 is fixedly provided with a telescopic device 111, and a telescopic rod 112 is poweredly connected to each of the left and right ends of the telescopic device 111. The telescopic rod 112 is fixedly connected to a fixing plate 113.

[0027] A movable plate 114 is fixedly connected to the lower end face of the telescopic rod 112. The movable plate 114 is rotatably connected to the movable shaft 115. The telescopic rod 112 is extended and retracted by the telescopic device 111, which can drive the fixed plate 113 and the movable plate 114 to move, thereby driving the movable shaft 115, the rotating wheel 116 and the rotating blade 117 to move, thereby adjusting the distance between the two rotating wheels 116.

[0028] Example 3:

[0029] Please see Figures 1-6 In order to facilitate the connection of the connecting pipe 101 to the petrochemical pipeline, a connecting ring 103 is provided;

[0030] Each end of the connecting pipe 101 is threaded with a connecting ring 103, which can be snapped into the petrochemical pipeline, thereby realizing the connection between the petrochemical pipeline and the connecting pipe 101.

[0031] Working principle and usage process of this utility model:

[0032] In use, the connecting pipe 101 is connected to the petroleum or other material transportation pipeline of the petrochemical industry through two connecting rings 103, and the speed detector 108 is connected to the electronic equipment through wireless signal.

[0033] At this time, the expansion joint 111 is activated, which causes the telescopic rod 112 to extend, thereby causing the two fixed plates 113, the two movable plates 114 and the two movable shafts 115 to move away from each other, thereby causing the two rotating wheels 116 to move away from each other. The petrochemical transported materials flow through the pipeline, and then the rotating blades 117 on the two rotating wheels 116 drive the two rotating wheels 116 to rotate, thereby driving the two detection shafts 109 to rotate.

[0034] The rotational speed of the two detection shafts 109 is detected by the speed detector 108. The flow rate difference can be obtained from the speed difference, and then it can be determined whether there is a pipe rupture and leakage between the two rotating wheels 116. Furthermore, by connecting multiple detection shells 105, the leakage and its location can be confirmed by the data from the multiple detection shells 105.

[0035] If the exact location of the leak is required, the expansion joint 111 is activated to extend or retract the expansion rod 112, which in turn moves the rotating wheel 116. The rotating wheel 116 can be moved to different positions to further confirm the location of the pipeline rupture and leak, facilitating maintenance and preventing leaks in petrochemical pipelines.
