[0031] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.

[0032] like Figure 1 , Figure 2 , Figure 8 and Fig.10 As shown, the utility model provides a wall opening sealing test device, which includes a static pressure panel assembly 1, a clamping mechanism 2, and an air pressure detection device 5. The static pressure panel assembly 1 has an inner side surface of a panel for abutting against a wall surface 31, and the inner side surface of the panel is provided with a sealing gasket 4 for being distributed around the wall opening 32, and the static pressure panel assembly 1 is provided with an air hole. The clamping mechanism 2 is configured to be able to press the static pressure panel assembly 1 against the wall surface 31, so that a closed space connected to the air hole is formed between the static pressure panel assembly 1, the closure 33 and the sealing gasket 4. The air pressure detection device 5 is connected to the air hole to detect the sealing of the closed space.

[0033] Specifically, the static pressure panel assembly 1 is laid on the wall surface 31, and the sealing gasket 4 is sealed between the wall surface 31 and the static pressure panel assembly 1, the pressing mechanism 2 is installed on the wall surface 31 and the static pressure panel assembly 1 is pressed against the wall surface 31, so that a closed space is formed between the static pressure panel assembly 1, the wall surface 31 and the sealing gasket 4. Then the air pressure detection device 5 is connected to the air hole of the static pressure panel assembly 1, so that the air pressure detection device 5 is connected to the closed space. Then the air pressure detection device 5 pressurizes the closed space so that the air pressure in the closed space reaches the rated pressure, and then the pressure in the closed space is monitored by the air pressure detection device 5. The air pressure detection device 5 can monitor the changes in the pressure of the closed space within a preset time period, and the detection personnel can understand the sealing condition according to the pressure changes.

[0034] In the present invention, the pressing mechanism 2 can press the static pressure panel assembly 1 against the wall surface 31, so that the static pressure panel assembly 1 will not fall off the wall surface 31; and the sealing gasket 4 can seal between the static pressure panel assembly 1 and the wall surface 31 to prevent air leakage between the static pressure panel assembly 1 and the wall surface 31, and the air pressure detection device 5 can obtain more accurate results after detecting the closed space. Therefore, the detection accuracy of the wall opening sealing test device of the present invention is relatively high.

[0035] like Figure 2 As shown, in some embodiments of the present invention, the static pressure panel assembly 1 includes a static pressure plate 13 and a fastener assembly 14 surrounding and detachably sealingly mounted on the outer periphery of the static pressure plate 13, and a sealing gasket 4 is connected to a side of the fastener assembly 14 facing the wall surface 31 and extends along the arrangement direction of the fastener assembly 14. The pressing mechanism 2 is configured to be able to press the fastener assembly 14 against the wall surface 31, so that a closed space is formed between the static pressure plate 13 and the closing member 33.

The sealing gasket 4 extends along the arrangement direction of the fastener assembly 14, so the sealing gasket 4 is arranged as a rectangular frame surrounding the wall opening 32. Of course, the fastener assembly 14 is detachably connected to the outer periphery of the static pressure plate 13 to facilitate disassembly and assembly.

[0037] like Figure 1 and Figure 2As shown, in some embodiments of the utility model, the static pressure plate 13 is set to a rectangular shape and includes a plurality of sub-panels 131 distributed in a matrix in the same plane. In the length direction of the static pressure plate 13, the two outermost rows of sub-panels 131 are sealed and connected to the fastener assembly 14 through a mortise and tenon structure, which is convenient for disassembly and helps to ensure the sealing. In the width direction of the static pressure plate 13, the two outermost rows of sub-panels 131 are sealed and plugged into the fastener assembly 14, and the connection method is simple, which is convenient for disassembly and helps to ensure the sealing. Two adjacent sub-panels 131 are detachably sealed and connected. Since the static pressure plate 13 is assembled from a plurality of sub-panels 131, according to the size of the wall opening 32, a corresponding number of sub-panels 131 can be selected for assembly to avoid the static pressure plate 13 being too large or too small, which helps to expand the application range of the wall opening sealing test device. The fastener assembly 14 can constrain all sub-panels 131 to make the static pressure panel assembly 1 stable and reliable.

[0038] like Figure 1 and Figure 2 As shown, an air pipe 12 is sealed and penetrated in the air hole of the static pressure plate 13.

A T-shaped first tenon 1312 is provided on the side of one of the connecting blocks facing away from the panel body 1311, and a first mortise 1313 is provided on the side of the other connecting block facing away from the panel body 1311, and the first tenon 1312 and the first mortise 1313 extend along the width direction of the static pressure plate 13. In addition, the first mortise 1313 penetrates the connecting block along the width direction of the static pressure plate 13, and the length of the first mortise 1313 and the length of the first tenon 1312 are equal to the width of the panel body 1311. For two adjacent panel bodies 1311, the first tenon 1312 of one panel body 1311 is assembled into the first mortise 1313 of the other panel body 1311, so that the two are assembled. Of course, for the panel bodies 1311 at the two edges, there will be a row of first tenons 1312 and a row of first mortise 1313 that are not connected to the other panel bodies 1311, but the first tenons 1312 and the first mortise 1313 are respectively sealed and connected to the fastener assembly 14 in the form of a mortise and tenon structure.

[0042] like Figures 1 to 4 As shown, in some embodiments of the present invention, in the width direction of the static pressure plate 13, every two adjacent rows of sub-panels 131 are detachably sealed and connected by an intermediate buckle plate 132. The intermediate buckle plate 132 can enhance the stability and reliability of the entire static pressure plate 13, prevent the two adjacent rows of sub-panels 131 from moving relative to each other, and prevent the middle portion of the static pressure plate 13 from deforming after being pressurized.

Both sides of each row of sub-panels 131 in the static pressure plate 13 in the width direction of the static pressure plate 13 are respectively sealed and connected with the two second gussets 143 through mortise and tenon structures.

[0046] Specifically, the first gusset plate 141, the second gusset plate 143 and the middle gusset plate 132 can connect all the sub-panels 131 into a sealed whole, and can maintain the seal between the static pressure plate 13 and the wall surface 31. In addition, the number of the second gusset plates 143 can be 4, 6 or 8, etc., and the utility model does not limit it. Of course, the side of the first gusset plate 141 facing the wall surface 31 and the side of the second gusset plate 143 facing the wall surface 31 are both distributed with sealing pads 4.

[0050] In addition, before testing the sealing of the wall opening 32, in order to further ensure the sealing of the static pressure panel assembly 1 and further ensure the accuracy of the test, a sealant may be applied to the assembly part, or a tape may be attached to the assembly part, or a plastic film may be bonded to the assembly part.

After the clamping mechanism 2 is fixed to the wall 3, the sealing gasket 4, the fastener components 14 and the clamping mechanism 2 overlap in a direction perpendicular to the wall surface 31 to ensure the sealing between the static pressure panel and the wall 3.
