Description

Technical Field

[0001] This utility model relates to the field of windproof devices, specifically to a windproof device for field penetration detection. Technical Background

[0002] Penetrant testing is a non-destructive testing technique based on the principle of capillary action, primarily used to detect surface opening defects in non-porous metallic or non-metallic components. When conducting penetrant testing in outdoor environments (such as soil penetrant testing, pipeline external corrosion protection layer penetrant testing, etc.), wind can have several adverse effects on the testing process. For example, wind may accelerate the volatilization of the penetrant, causing changes in penetrant concentration and affecting the penetrant's effectiveness.

[0003] Existing windproof devices for field penetration testing commonly include temporary handheld windbreaks and fixed prefabricated metal barriers. Temporary barriers are weak in wind resistance, while fixed barriers cannot be moved and are not very convenient, making them difficult to adapt to the field environment. Furthermore, the complete sealing of the four sides of the barrier can easily lead to airflow stagnation inside the barrier (affecting some penetration testing equipment that relies on trace amounts of airflow). However, insufficient airtightness cannot block crosswinds, resulting in an imbalance between sealing and ventilation. Utility Model Content

[0004] (I) Technical Issues

[0005] The technical problem this invention aims to solve is that existing field penetration detection windproof devices are fixed and cannot be moved, which is not convenient. The complete sealing of the four sides of the enclosure can easily lead to airflow stagnation, resulting in an imbalance between sealing and ventilation.

[0006] (II) Technical Solution

[0007] To solve the above technical problems, this solution provides an outdoor penetration detection windproof device, which is achieved through the following technical means:

[0008] An outdoor infiltration detection windproof device includes a support column, a support plate, a base plate at the lower end of the support column, and track grooves on all four sides of the support column that are inserted into the support plate. It also includes a support structure that can be detachably connected to one side of the support column and an adjustable ventilation structure on the support plate.

[0009] As an improvement, the ventilation structure includes two door panels with handles on them. Both the upper and lower ends of the door panels are slidably connected to several guide rails set on a support plate. The support plate is also provided with dense ventilation holes, which can be completely covered by the door panels.

[0010] As an improvement, carrying handles are fixedly connected to both sides of one side of the support plate.

[0011] As an improvement, the two adjacent sides of the support column are threaded with fastening screws that mate with the track groove, and the fastening screws are threaded with locking nuts.

[0012] As an improvement, a flange is provided in the middle of the fastening screws near the top and bottom ends of the support column. The support structure includes a support diagonal rod, one end of which is fixedly connected to a support plate, and the other end is provided with a connecting flange that connects to the flange. The support column and the support diagonal rod are connected by bolts.

[0013] As an improvement, mounting holes are provided at all four corners of the base plate, and several positioning holes are also provided on the support plate, which can be fixed by passing ground nails through the mounting holes and positioning holes.

[0014] (III) Technical Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The support column has track grooves on all four sides that can be inserted into the support plate. The support plate and support column can be placed separately when not in use. When in use, the appropriate number of support columns and support plates can be selected and inserted according to the space required for the off-site permeation test. The size of the windproof device can be controlled at will, which is highly flexible.

[0017] 2. Both sides of the adjacent support column are threaded with fastening screws that mate with the track groove. The fastening screws are threaded with locking nuts. After the support plate is inserted into the support column, the fastening screws can be locked with the locking nuts to better fix the support plate.

[0018] 3. An adjustable ventilation structure is set on the support plate. By pushing or pulling the door panel that is slidably connected in the guide rail on the support plate, the ventilation volume can be controlled by controlling the exposed area of ​​the ventilation holes on the support plate.

[0019] 4. The support column is also connected to a support structure by bolts. By passing ground nails through the positioning holes on the support plate, the support structure can be fixed and provide an oblique support for the support column. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] An outdoor penetration detection windproof device, such as Figure 1 , Figure 3 As shown, it includes:

[0029] The system includes a support column 1, a support plate 7, and a base plate 2 at the lower end of the support column 1. The support column 1 has four track grooves 3 on its four sides that are inserted into the support plate 7. The support plate 7 is connected to the support column 1 through the track grooves 3. The adjacent two sides of the support column 1 are threaded with fastening screws 5 that are in sync with the track grooves 3. Locking nuts 6 are threaded onto the fastening screws 5. After the support plate 7 is inserted into the support column 1, the fastening screws 5 can be locked by the locking nuts 6, which provides better fixation for the support plate 7. It also includes a detachable support structure on one side of the support column 1 and an adjustable ventilation structure on the support plate 7. The support column 1 has a flange 17 in the middle of the fastening screws 5 near the upper and lower ends. The support structure includes a support diagonal rod 14, which plays a role in diagonal support. One end of the support diagonal rod 14 is fixedly connected to the support plate 15, and the other end is provided with a connecting flange 13 connected to the flange 17. The support column 1 and the support diagonal rod 14 are connected by bolts. The four corners of the base plate 2 are provided with mounting holes 4. The support plate 15 is also provided with several positioning holes 16. By passing the ground nail through the positioning holes 16 on the support plate 15 and the mounting holes 4 on the base plate 2, the support column 1 can be fixed on the ground, and the support structure as a whole plays a role in diagonal support for the support column 1.

[0030] like Figure 2 , Figure 4 As shown, the ventilation structure includes two door panels 10, each with a handle 12 for easy pushing and pulling. Both the upper and lower ends of each door panel 10 are slidably connected to several guide rails 9 mounted on a support plate 7. Three guide rails 9 are arranged parallel to each other vertically. The two door panels 10 slide vertically between two adjacent guide rails 9. The support plate 7 also has densely packed ventilation holes 11, which can be completely covered by the door panels 10. The ventilation volume is controlled by pushing and pulling the door panels 10 slidably connected to the guide rails 9 using the handles 12, thus controlling the exposed area of ​​the ventilation holes 11. Handles 8 are fixedly connected to both sides of one side of the support plate 7 for easy handling and assembly.

[0031] In the specific implementation of this embodiment:

[0032] In use, select the appropriate number of support columns 1 and support plates 7 according to the space required for the field infiltration test. Insert the ground nails through the mounting holes 4 on the base plate 2 and into the soil to fix the support columns 1 on the ground. Then, move the support plates 7 by the handling handle 8 and insert them into the track groove 3 of the support column 1. Press the fastening screws 5 against the support plates 7 and rotate the locking nut 6 to tighten the fastening screws 7, so that the support plates 7 are firmly fixed. Connect the connecting flange 13 on the support structure to the flange 17 on the support column 1 with bolts. Then, insert the ground nails through the positioning holes 16 on the support plate 15 into the soil so that the support structure provides oblique support for the support column 1. The area of ​​the vent 11 on the support plate 7 can be controlled by pushing and pulling the door panel 10 slidably connected in the guide rail 9 on the support plate 7 according to the wind force outside the field. This controls the air volume, prevents airflow stagnation, and avoids excessive air volume from affecting the infiltration effect.

[0033] After use, the support column 1, support plate 7, and support structure can be disassembled, sorted, and stored for future use, saving space.
