Description

Technical Field

[0001] This utility model relates to the field of moisture-proof technology, specifically to a moisture-proof device for dry-hanging decorative walls in underground spaces. Background Technology

[0002] With the acceleration of urbanization, the development and utilization of underground space has become an important development direction of modern architecture. Underground facilities generally use dry-hanging decorative walls as the decorative surface layer of the enclosure structure. In areas with high humidity, the walls are susceptible to the effects of groundwater infiltration and condensation, requiring corresponding moisture-proof measures. Chinese Patent No. CN222667415U discloses a wall decorative panel, including a decorative panel and a protective component. The protective component includes a sound insulation layer set at one end of the inner wall of the decorative panel, which is composed of sound insulation cotton. A moisture-proof layer is set at one end of the sound insulation layer, which is composed of plywood.

[0003] Conventional moisture-proofing methods involve installing a moisture-proof layer within the wall, applying waterproof coatings, laying waterproof membranes, and filling with moisture-proof boards, relying on waterproof materials to prevent moisture from diffusing into the indoor space. However, in practical applications, the performance of moisture-proof materials deteriorates due to factors such as construction time and complex underground environments. Moisture that has penetrated the structure continues to accumulate in the cavities of the dry-hanging decorative wall, seeping out from the wall surface and causing mold growth on the decorative layer. Although existing technologies employ passive drainage measures such as adding drainage holes or water channels, the humidity inside the cavities continues to rise, and the drainage system is easily clogged by deposits. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a moisture-proof device for dry-hanging decorative walls in underground spaces. This device solves the problem that relying solely on a moisture-proof layer for moisture protection in underground spaces can easily lead to performance degradation due to construction time and environmental factors, resulting in the decorative layer becoming damp and moldy.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a moisture-proof device for dry-hanging decorative walls in underground spaces, comprising an outer wall, an inner wall, decorative panels, a guide pipe, a receiving pipe, an air supply channel, and a dredging mechanism. A cavity is left between the outer wall and the inner wall. A decorative panel is fixedly installed on the side of the inner wall away from the outer wall. A guide pipe is fixedly installed on the side of the outer wall and the side of the inner wall close to each other, and the guide pipe is fitted to the inner wall of both. A receiving pipe is fixedly installed at the bottom of the cavity between the outer wall and the inner wall, and the receiving pipe is fitted to the inner wall of both. An air supply channel is fixedly installed on the side of the inner wall close to the outer wall.

[0006] A dredging mechanism is fixedly installed on the side of the exterior wall and the inner wall that are close to each other. The dredging mechanism includes a dredging component and a pneumatic component. The dredging component is fixedly installed on the inner wall of the exterior wall and the inner wall that are close to each other, and the rotating end of the dredging component is set in a corresponding manner with the water inlet of the guide pipe. The pneumatic component is fixedly installed on the inner wall of the exterior wall and the inner wall that are close to each other, and the rotating end of the pneumatic component is set in a corresponding manner with the rotating end of the dredging component.

[0007] The guide pipe includes a main pipe and a secondary pipe. The main pipe is fixedly installed on the outer wall and the inner wall near the inner wall. Secondary pipes are fixedly installed on the left and right sides of the main pipe.

[0008] The outlet pipe of the receiving pipe is located directly below the bottom outlet of the main pipe, and the outlet pipe of the receiving pipe passes through the inner wall to the space between the inner wall and the decorative panel.

[0009] The number of air supply channels is two sets. The air inlets and outlets of the two sets of air supply channels are arranged in parallel and in opposite directions. The air outlet pipes and air inlet pipes of the two sets of air supply channels pass through the inner wall to the space between the inner wall and the decorative panel.

[0010] The unblocking mechanism includes a fixed frame, a rotating plate, and an unblocking insert. The fixed frame is fixedly installed on the inner wall near the outer wall and the inner wall. The rotating plate is rotatably installed on the surface of the fixed frame, and a torsion spring is provided at the rotation point of the fixed frame and the rotating plate. The unblocking insert is fixedly installed at one end of the rotating plate.

[0011] The pneumatic components of the unblocking mechanism include fan blades and baffles. The fan blades are rotatably installed on the inner wall of the outer wall and the inner wall, which are close to each other. The baffles are fixedly installed on the inner wall of the outer wall and the inner wall, which are close to each other.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention separates the underground space through cavities in the exterior and interior walls. This allows external moisture to seep out through the exterior walls after passing through the deteriorating moisture-proof layer. Most of the liquid water flows from the secondary pipe into the main pipe and continues into the receiving pipe. The remaining liquid water flows from the surface of the main pipe into the receiving pipe and is discharged to the outside through the outlet pipe of the receiving pipe. By connecting the ventilation equipment to the ventilation duct, the moisture in the cavities of the exterior and interior walls is blown out, thus preventing moisture penetration due to performance degradation caused by aging of the moisture-proof layer and environmental factors. In underground spaces, to improve moisture-proof performance, the baffle guides airflow, causing the fan blades to rotate unidirectionally due to the airflow from the air supply channel. The fan blades push the lever of the rotating plate, causing the rotating plate to rotate. The rotating plate then rotates the unblocking insert, which is inserted into the connection between the main pipe and the secondary pipe. When dust and debris carried by moisture fall to this point, it prevents them from accumulating and clogging at the narrow flow channel of the secondary pipe, thus hindering the flow of liquid water. The torsion spring at the connection between the rotating plate and the fixed frame causes the rotating plate to rotate in the opposite direction, pushing the unblocking insert back to its original position.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 5 The present invention will be further described below.

[0022] A moisture-proof device for a dry-hanging decorative wall in an underground space includes an outer wall 1, an inner wall 2, decorative panels 3, a guide pipe 4, a receiving pipe 5, an air supply duct 6, and a drainage mechanism 7. A cavity is left between the outer wall 1 and the inner wall 2. Decorative panels 3 are fixedly installed on the side of the inner wall 2 away from the outer wall 1. Guide pipes 4 are fixedly installed on the sides of both the outer wall 1 and the inner wall 2, and the guide pipes 4 are fitted against the inner walls of both. A receiving pipe 5 is fixedly installed at the bottom of the cavity between the outer wall 1 and the inner wall 2, and the receiving pipe 5 connects to the inner walls of both walls. The inner walls of the device are fitted together. An air supply duct 6 is fixedly installed on the side of the inner wall 2 closest to the outer wall 1. A dredging mechanism 7 is fixedly installed on the side of the outer wall 1 and the inner wall 2 that is close to each other. The dredging mechanism 7 includes a dredging component and a pneumatic component. The dredging component is fixedly installed on the inner walls of the outer wall 1 and the inner wall 2 that are close to each other. The rotating end of the dredging component is corresponding to the water inlet of the guide pipe 4. The pneumatic component is fixedly installed on the inner walls of the outer wall 1 and the inner wall 2 that are close to each other. The rotating end of the pneumatic component is corresponding to the rotating end of the dredging component.

[0023] Specifically, the cavity between the outer wall 1 and the inner wall 2 forms a space for water vapor infiltration. The water vapor seeping out of the cavity between the outer wall 1 and the inner wall 2 is received by the diversion pipe 4. The water flowing out of the diversion pipe 4 is received by the receiving pipe 5 and discharged to the outside. The water vapor remaining in the cavity between the outer wall 1 and the inner wall 2 is blown out by the air supply channel 6 in conjunction with the external air supply equipment. The pneumatic component of the unblocking mechanism 7 is driven to rotate by the airflow blown by the air supply channel 6. The rotating end of the pneumatic component pushes the rotating end of the unblocking component to rotate, and the unblocking component unblocks the diversion pipe 4.

[0024] The guide pipe 4 includes a main pipe 401 and a secondary pipe 402. The main pipe 401 is fixedly installed on the inner wall of the outer wall 1 and the inner wall 2, and the secondary pipes 402 are fixedly installed on the left and right sides of the main pipe 401.

[0025] Specifically, the water vapor seeping from the decorative panel 3 is guided by the secondary pipe 402 to condense into liquid water, which is then collected and flows into the guide pipe 4 more quickly, reducing its residence time in the cavity between the outer wall 1 and the inner wall 2. The liquid water collected at the secondary pipe 402 is then sent to the outlet pipe of the receiving pipe 5 through the main pipe 401.

[0026] The outlet pipe of the receiving pipe 5 is located directly below the bottom outlet of the main pipe 401, and the outlet pipe of the receiving pipe 5 passes through the inner wall 2 to the space between the inner wall 2 and the decorative panel 3.

[0027] Specifically, the liquid water appearing on the surface of the guide pipe 4 is collected and discharged through the receiving pipe 5, and the liquid water discharged from the outlet of the main pipe 401 is promptly guided and transported to the outside.

[0028] There are two sets of air supply channels 6. The air inlets and outlets of the two sets of air supply channels 6 are set in parallel and in opposite directions. The air outlet pipes and air inlet pipes of the two sets of air supply channels 6 pass through the inner wall 2 to the space between the inner wall 2 and the decorative panel 3.

[0029] Specifically, the system operates by supplying and exhausting air through two sets of air supply channels 6. The air supply channel 6 blows airflow that carries water vapor from the cavities of the outer wall 1 and inner wall 2 into a circulating flow, and then sends it out to the outside through the exhaust air supply channel 6.

[0030] The unblocking mechanism 7 includes a fixed frame 701, a rotating plate 702, and an unblocking insert 703. The fixed frame 701 is fixedly installed on the inner wall of the outer wall 1 and the inner wall 2. The rotating plate 702 is rotatably installed on the surface of the fixed frame 701, and a torsion spring is provided at the rotation point of the fixed frame 701 and the rotating plate 702. The unblocking insert 703 is fixedly installed at one end of the rotating plate 702. The rotation path of the unblocking insert 703 passes through the connection between the main pipe 401 and the secondary pipe 402. A lever is fixedly installed at the other end of the rotating plate 702.

[0031] Specifically, the rotation of the rotating plate 702 drives the unblocking insert 703 to swing, so that the unblocking insert 703 blocks and unblocks the connection between the main pipe 401 and the secondary pipe 402. The torsion spring pulls the rotating plate 702, which pushes the unblocking insert 703 into the guide pipe 4, back to its original position. The lever causes the rotation of the pneumatic component to drive the unblocking component to swing back and forth.

[0032] The pneumatic components of the unblocking mechanism 7 include a fan blade 704 and a baffle plate 705. The fan blade 704 is rotatably installed on the inner wall of the outer wall 1 and the inner wall 2. The levers of the fan blade 704 and the rotating plate 702 are arranged in a corresponding manner. The baffle plate 705 is fixedly installed on the inner wall of the outer wall 1 and the inner wall 2, and the receiving pipe 5 is located above the fan blade 704.

[0033] Specifically, the baffle 705 blocks the airflow and restricts the direction of the fan blade 704. The fan blade 704 is blown by the airflow, thereby driving the unblocking plate 703 to perform the unblocking operation.

[0034] In summary: When using this utility model, the workers install the device inside the outer wall 1 and inner wall 2, and connect the water outlet pipe of the receiving pipe 5 and the exhaust pipe of the air supply channel 6 to the underground drainage pipe. The air supply equipment is connected to the air inlet pipe of the air supply channel 6. During humid seasons or in humid areas, the moisture-proof layer on the decorative panel 3 is difficult to bend and prevent moisture penetration. Moisture enters the cavity between the outer wall 1 and inner wall 2, and the condensed liquid water slides from the surface of the outer wall 1 and inner wall 2 to the secondary pipe 402, and then flows through the secondary pipe 402 to the water outlet pipe of the receiving pipe 5 for discharge. Some of the liquid water condensed on the surface of the guide pipe 4 also flows into the receiving pipe 5 for discharge, accelerating the discharge of moisture and reducing the time moisture remains in the cavity between the outer wall 1 and inner wall 2. When the air supply equipment is activated, airflow is blown into the cavity between the outer wall 1 and the inner wall 2 through a set of air supply channels 6. The airflow, carrying water vapor, passes through the cavity and is discharged through another set of air supply channels 6. At the same time, when the airflow is blown to the baffle plate 705, it is guided by the baffle plate, causing the airflow to drive the fan blade 704 to rotate in one direction. The rotating fan blade 704 continuously pushes the lever of the rotating plate 702, causing the rotating plate 702 to rotate and drive the unblocking insert 703 to be inserted into the narrow connection between the secondary pipe 402 and the main pipe 401. Due to the small water flow, water carrying dust and debris is prone to blockage here. The torsion spring drives the unblocking insert 703 to reset, so that the unblocking insert 703 continuously reciprocates to unblock the area and ensure the rapid discharge of condensed water.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
