DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides an auxiliary device for detecting anti-corrosion layers of buried pipelines, comprising a liquid collecting bag 100, a liquid dispensing tube 102 and a bracket 104; the liquid collecting bag 100 is filled with a contact medium; the liquid dispensing tube 102 is fluidically connected to the liquid collecting bag 100; the bracket 104 comprises a support leg 106, to which a metal seat 108 is movably connected, the metal seat 108 is fluidically connected to the liquid dispensing tube 102 and the metal seat 108 is filled with a sponge.

[0027] According to the auxiliary device for detecting the anti-corrosion layer of the buried pipeline provided by the embodiment of the utility model, the contact medium in the liquid collecting bag 100 is connected to the liquid dispensing tube 102, so that the flow of the contact medium is realized, thereby providing the necessary contact medium for detecting the anti-corrosion layer. The contact medium can be selected from different types of contact media such as water and salt water, which can effectively reduce the contact resistance of the contact surface, enhance the conduction of the signal, and make the detection result more reliable; or it can simulate the natural laying environment of the pipeline, so that the detection result is closer to the actual situation, and then evaluate the quality and integrity of the anti-corrosion layer. The design of the bracket 104 allows the metal seat 108 to be movably connected on the support leg 106, and the fluid connection between the metal seat 108 and the liquid dispensing tube 102 ensures that the contact medium can be evenly distributed on the contact surface, thereby improving the accuracy and reliability of the detection. When used on the ground such as grass, the metal seat 108 can be folded up to reduce the workload of the user using the auxiliary device. The structure of the device is relatively simple and easy to install and operate. By adjusting the position of the bracket 104 and the metal seat 108, different positions and different types of ground can be quickly detected, which greatly improves the detection efficiency. Using contact media as the detection medium is safer and more environmentally friendly than other media that may pollute the environment. In addition, through reasonable structural design, safety performance during operation is ensured and the probability of accidents is reduced.

[0028] Please continue to see Figure 1 to Figure 2 The embodiment of the utility model provides an auxiliary device for detecting the anti-corrosion layer of a buried pipeline. The device mainly consists of three parts: a liquid collecting bag 100, a liquid dispensing tube 102 and a bracket 104.

[0029] The liquid collection bag 100 is one of the core parts of the device, and its main function is to store and supply the contact medium required for detection. In the present invention, the liquid collection bag 100 is filled with a contact medium, which is usually a liquid that can improve the ground resistance, such as salt water, water or other special detection liquid. The design of the liquid collection bag 100 should ensure that the liquid can be stably stored and easily transported to the liquid distribution tube 102 through a pipeline.

[0030] In addition, for the convenience of carrying, a shoulder strap 126 is provided on the liquid collection bag 100. By providing the shoulder strap 126 on the liquid collection bag 100, it is convenient for users to carry.

[0031] The liquid dispensing tube 102 is in fluid communication with the liquid collecting bag 100, and its main function is to evenly distribute the contact medium in the liquid collecting bag 100 to the anti-corrosion layer of the pipeline. The design of the liquid dispensing tube 102 should ensure that the liquid can flow smoothly and does not cause blockage or leakage during the transportation process. In addition, the liquid dispensing tube 102 should also have a certain length and flexibility to adapt to pipelines of different lengths and curvatures.

[0032] The bracket 104 is the basic part of the auxiliary device, and its main function is to fix and support the liquid dispensing tube 102. The bracket 104 includes a support leg 106, which can be stably placed on the ground or other planes to ensure the stability and safety of the entire device. A metal seat 108 is movably connected to the support leg 106, and the metal seat 108 is fluidically connected to the liquid dispensing tube 102. The design of the metal seat 108 should be able to fit tightly on the ground to ensure that the contact medium can be evenly distributed on the ground. The movable design of the metal seat 108 enables the device to adapt to pipes of different diameters and shapes, thereby improving the applicability and flexibility of the device. In addition, by movably setting the metal seat 108 on the bracket 104, when it is necessary to inject the contact medium into the ground, the contact medium can be injected into the sponge; when it is not necessary to inject the contact medium into the ground, the metal seat 108 can be directly removed so that the support leg 106 is directly in contact with the ground. In this way, the accuracy and scope of application of the detection can be improved.

[0033] The auxiliary device provided by the utility model can quickly and evenly distribute the contact medium on the ground, thereby realizing efficient detection of the anti-corrosion layer. This detection method can timely discover defects and damage in the anti-corrosion layer, and provide accurate data support for the repair and maintenance of the pipeline. The design of the movable metal seat 108 on the bracket 104 enables the device to adapt to different types of ground, improving the applicability and flexibility of the device. The entire device has a simple structure and is easy to operate, without the need for complicated installation and debugging processes. The operator only needs to place the bracket 104 near the pipeline, adjust the position and angle of the metal seat 108, and then start the detection work. The stability of the bracket 104 and the close fit of the metal seat 108 ensure the safety of the device during the detection process. At the same time, the design of the liquid collection bag 100 and the liquid distribution tube 102 also ensures the stability and safety of the liquid during the transportation process, avoiding the occurrence of problems such as leakage and blockage.

[0034] To sum up, the auxiliary device for detecting the anti-corrosion layer of buried pipelines provided by the embodiment of the utility model has the advantages of efficient detection, strong applicability, simple operation, safety and reliability, and provides an effective solution for the detection of the anti-corrosion layer of buried pipelines.

[0035] According to an embodiment of the present invention, the bracket 104 further includes a leg 110 , the leg 110 is connected to the foot 106 , and the liquid dispensing tube 102 is installed on the leg 110 .

[0036] See also Figure 2The support leg 106 is the part of the support 104 that contacts the ground or other planes, and is used to ensure the stability of the entire device. The support leg 110 is connected to the support leg 106, providing additional support and stability for the support 104. The liquid dispensing tube 102 is installed on the support leg 110. This design can ensure that the liquid dispensing tube 102 maintains a stable position and angle during the detection process, and further ensures that the contact medium can be evenly distributed on the pipeline anti-corrosion layer.

[0037] By introducing the design of the legs 110 and combining it with the feet 106, the stability of the entire bracket 104 is significantly improved. This design allows the device to maintain a stable detection state even in a complex environment, thereby improving the accuracy and reliability of the detection. Since the liquid dispensing tube 102 is installed on the legs 110, its position and angle are better fixed and controlled. This helps to ensure that the contact medium can be more evenly distributed on the pipeline anti-corrosion layer, thereby improving the accuracy and efficiency of the detection.

[0038] According to an embodiment of the present invention, a fixing buckle 112 is disposed on the support leg 110 , and a first liquid inlet pipe 114 is disposed between the metal seat 108 and the liquid dispensing tube 102 . The first liquid inlet pipe 114 is fixed to the fixing buckle 112 .

[0039] See also Figure 2 The support leg 110 not only provides support for the device, but also has a fixing buckle 112 disposed thereon. The fixing buckle 112 is used to fix the first liquid inlet pipe 114, ensuring the stability and position of the first liquid inlet pipe 114 during the detection process. The first liquid inlet pipe 114 is fixed in the fixing buckle 112 on the support leg 110. This design makes it difficult for the first liquid inlet pipe 114 to move or deform during the detection process, thereby ensuring that the contact medium can be stably and evenly distributed in the sponge and then flow to the ground.

[0040] By providing a fixing buckle 112 on the leg 110 and fixing the first liquid inlet pipe 114 thereon, the stability of the device is greatly enhanced. Even in a complex or bumpy environment, the position and angle of the first liquid inlet pipe 114 can be ensured to remain unchanged, thereby ensuring the accuracy of the detection result. Since the first liquid inlet pipe 114 is stably fixed, it can ensure that the contact medium is transported to the metal seat 108 at a constant flow rate and flow rate, so that it is more evenly distributed on the pipeline anti-corrosion layer. This helps to improve the accuracy and efficiency of the detection.

[0041] According to an embodiment of the present invention, a plurality of fixing buckles 112 are provided on the leg 110 along the length direction of the leg 110 .

[0042] A plurality of fixing buckles 112 are provided along the length direction of the leg 110. These fixing buckles 112 are used to fix the first liquid inlet pipe 114 or other accessories related to the liquid dispensing pipe 102. By providing a plurality of fixing buckles 112, the position and angle of the first liquid inlet pipe 114 or other pipes can be flexibly adjusted as needed.

[0043] By providing a plurality of fixing buckles 112 on the legs 110, the position and angle of the first liquid inlet pipe 114 or other pipes can be flexibly adjusted according to actual detection requirements. This design improves the flexibility and adaptability of the device. Since the first liquid inlet pipe 114 or other pipes are stably fixed, the contact medium can be transported to the metal seat 108 at a more stable and uniform flow rate and flow rate, and then distributed on the ground, which helps to improve the accuracy and efficiency of detection.

[0044] According to an embodiment of the present invention, there are two supporting legs 110 , a connecting rod 116 is disposed between the two supporting legs 110 , and the metal seat 108 is hinged to the supporting legs 110 or the connecting rod 116 .

[0045] A connecting rod 116 is provided between the legs 110. The function of the connecting rod 116 is to strengthen the connection between the two legs 110, so that the structure of the entire bracket 104 is more stable. Through the design of the two legs 110 and the connecting rod 116, the overall structure of the bracket 104 is more stable and can withstand greater external forces. At the same time, the hinged design of the metal seat 108 and the legs 110 or the connecting rod 116 makes the device more adaptable, improving the adaptability and flexibility of the device.

[0046] According to an embodiment of the present invention, the distance between the two legs 110 gradually increases from the liquid dispensing tube 102 to the metal seat 108 .

[0047] By such an arrangement, the support stability of the bracket 104 is improved, ensuring that the support frame will not shake during use, thereby effectively ensuring the accuracy of the detection.

[0048] According to an embodiment of the present invention, a second liquid inlet pipe 118 is connected between the liquid collecting bag 100 and the liquid dispensing pipe 102 , and a flow meter 120 is connected to the second liquid inlet pipe 118 .

[0049] The liquid collection bag 100 and the liquid dispensing tube 102 are connected via a second liquid inlet pipe 118, which is responsible for conveying the contact medium in the liquid collection bag 100 to the liquid dispensing tube 102. A flow meter 120 is connected to the second liquid inlet pipe 118. The function of the flow meter 120 is to monitor and record the flow of the medium passing through the second liquid inlet pipe 118 in real time. Through the flow meter 120, the operator can accurately grasp the flow of the medium, thereby ensuring that the medium supply during the detection process is stable and meets the requirements.

[0050] By introducing the flow meter 120, operators can grasp the medium flow in real time, ensure that the medium supply during the inspection process is stable and meets the requirements, and thus improve the accuracy of the inspection. The flow data recorded by the flow meter 120 can provide accurate data support for subsequent data analysis and reporting, which helps to more comprehensively understand the situation of the pipeline anti-corrosion layer.

[0051] According to one embodiment of the utility model, a liquid storage portion 122 is provided on the bracket 104, the second liquid inlet pipe 118 is connected between the liquid collecting bag 100 and the liquid storage portion 122, the liquid distribution tube 102 is connected to the liquid storage portion 122, and a switch is provided between the liquid distribution tube 102 and the liquid storage portion 122 and / or on the second liquid inlet pipe 118.

[0052] The liquid storage part 122 is arranged on the bracket 104, and is used for temporarily storing the contact medium transported from the liquid collection bag 100. The design of the liquid storage part 122 takes into account factors such as the storage capacity of the medium and the convenience of observing the remaining amount of the medium. The liquid distribution tube 102 is connected to the liquid storage part 122, and is used to evenly distribute the contact medium in the liquid storage part 122 to the anti-corrosion layer of the pipeline. In order to control the flow of the liquid, a switch is provided between the liquid distribution tube 102 and the liquid storage part 122 and / or on the second liquid inlet pipe 118. These switches can be manual switches or automatic switches, which are selected according to specific needs. By controlling the opening and closing of the switch, the operator can accurately control the flow speed and flow rate of the contact medium to meet different detection requirements.

[0053] By providing the liquid storage part 122, the device can work without being directly connected to the liquid collection bag 100, which increases the flexibility and convenience of the device. The introduction of the switch can accurately control the flow speed and flow rate of the liquid, improving the accuracy and efficiency of the detection. The provision of the liquid storage part 122 makes the device more convenient when maintaining and replacing the medium, reducing the workload of the operator.

[0054] According to an embodiment of the present invention, a probe 124 is disposed on the foot, and the metal seat 108 can movably cover the probe 124 .

[0055] The main function of the probe 124 is to be directly inserted into relatively soft ground such as grass. In this embodiment, the metal seat 108 is designed to be movably covered on the probe 124. This design allows the metal seat 108 to be adjusted according to the actual conditions of the ground. When the ground is relatively dry, the contact medium can be filled into the sponge of the metal seat 108. When the ground is relatively soft, the probe 124 can be directly inserted into the ground to provide sufficient flexibility and adaptability.

[0056] This embodiment further improves the practicality and performance of the auxiliary device for detecting the anti-corrosion layer of buried pipelines by arranging the probe 124 on the foot and designing the metal seat 108 to movably cover the probe 124. This design enhances the adaptability and detection efficiency of the device. In practical applications, the device can more effectively evaluate the quality and condition of the pipeline anti-corrosion layer, providing strong support for pipeline maintenance and repair.
