Description

Technical Field

[0001] This utility model relates to the field of storage tank permeation detection technology, specifically a storage tank permeation detection device. Background Technology

[0002] When there are minor defects in the tank wall, the penetrant can penetrate into these defects. Through specific detection methods, the distribution of the penetrant at the defect can be observed, and the integrity of the tank wall can be determined. Tank penetrant testing is used in industries such as petroleum, chemical and food processing to test various types of tanks, such as steel tanks, concrete tanks and plastic tanks.

[0003] In existing technologies, penetrant is sprayed using a spray can for testing. However, during the testing process, the penetrant often splashes into non-test areas, requiring staff to clean up excess penetrant before spraying the developer. This not only increases the workload but also reduces the efficiency of penetrant testing due to the cumbersome process, thus exacerbating labor costs and wasting time. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: A permeation detection device for a storage tank includes a support base 1. The support base 1 has two receiving cavities 2 inside. A connecting pipe 3 is fixedly connected to the bottom end of the support base 1 at the position corresponding to the receiving cavity 2. A water pump 4 is fixedly installed on the outer wall of the support base 1. A delivery pipe 5 is fixedly connected to the top output port of each water pump 4. A nozzle 6 is fixedly connected to one end of each delivery pipe 5. A cover 10 is threadedly connected to each receiving cavity 2. The top end of each connecting pipe 3 is connected to the corresponding receiving cavity 2. The other end of each connecting pipe 3 is fixedly connected to and connected to the bottom output port of the corresponding water pump 4. Both the connecting pipe 3 and the delivery pipe 5 are rigid pipes. A handle 11 is fixedly connected to the outer wall of the support base 1. One end of each delivery pipe 5 is connected to the top output port of each water pump 4. The other end of each delivery pipe 5 is connected to the nozzle 6.

[0020] In use, the support base 1 can be held by the handle 11, and then the penetrant and developer can be added into the container cavity 2 respectively. When penetrant spraying test is required at the weld joint of the storage tank, the corresponding water pump 4 is started. The water pump 4 will draw out the penetrant in the corresponding container cavity 2 through the connecting pipe 3, and then spray it out through the delivery pipe 5 and the nozzle 6. The sprayed penetrant will adhere to the area of ​​the storage tank to be tested. After waiting for the penetrant to penetrate the storage tank, another water pump 4 is started. The water pump 4 will draw out the developer in the container cavity 2 through the corresponding connecting pipe 3, and then spray it out through the delivery pipe 5 and the nozzle 6. The sprayed developer will cover the penetrant. At this time, the penetrant that has penetrated at the test area will be lit by the developer. The staff can observe the penetrant to obtain the test result of the weld joint of the storage tank. When the developer or penetrant is used up, the cover 10 can be rotated to separate the cover 10 from the container cavity 2, and then the corresponding container cavity 2 can be refilled.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a pressing rod 7 is slidably connected to the support base 1, a pushing block 8 is fixedly connected to one end of the pressing rod 7, a locking mechanism 9 is provided on the conveying pipe 5, the locking mechanism 9 includes a mounting base 91, a symmetrically arranged rotating rod 92 is rotatably connected to the mounting base 91, a torsion spring 93 is fixedly connected to the mounting base 91 at the position corresponding to the rotating rod 92, a support rod 94 is fixedly connected to the middle position of the rotating rod 92, a baffle 95 is fixedly connected to one side of the support rod 94, and a connecting belt 96 is fixedly connected between the baffles 95;

[0022] The other end of the extrusion rod 7 is arc-shaped, the baffle 95 is a transparent plate, the mounting base 91 is fixedly connected to the two conveying pipes 5, the top of the rotating rod 92 passes through the center position of the corresponding torsion spring 93, and the top of the torsion spring 93 is fixedly connected to the bottom of the corresponding support rod 94.

[0023] In use, the support base 1 is held by the handle 11. Before spraying the penetrant, the push block 8 can be pressed. The push block 8 will move towards the support base 1, and will drive the extrusion rod 7 to move together. The extrusion rod 7, with its curved part, will extrude pressure on the middle part of the connecting belt 96. When the middle part of the connecting belt 96 is compressed, both ends of the connecting belt 96 will pull on the baffles 95. At this time, both baffles 95 will drive the support rod 94 and the rotating rod 92 to rotate. The rotation of the baffles 95 is centered on the rotating rod 92. When the support rod 94 rotates, it will cause the torsion spring 93 to twist. Then the two baffles 95 will rotate and open in opposite directions. This can be controlled according to the size of the tank weld. The two baffles 95 are opened to the desired size. After the baffles 95 are fully opened, they are placed over the welded area of ​​the storage tank. Then, the nozzle 6 is controlled to spray the penetrant. The staff can observe the spraying situation at the welded area through the transparent baffles 95. The splashed penetrant will be blocked by the baffles 95, preventing the penetrant from being sprayed on other points. This eliminates the tedious step of manually wiping off excess penetrant in the traditional process, improves the efficiency of penetrant testing, and reduces the energy consumption of the staff. After the penetrant penetration is completed, the developer can be sprayed directly to obtain the penetrant penetration test results. When the baffles 95 need to be reset, simply release the push block 8, and the torsion spring 93 will drive the support rod 94 and the baffles 95 to reset to their original positions.
