Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof testing technology for boards, and in particular to a waterproof testing device for polyurethane boards. Background Technology
[0002] Polyurethane boards are functional boards made primarily of polyurethane (PU). After production, they need to undergo waterproof testing. Waterproof testing is a process that evaluates their waterproof performance, water resistance, and sealing properties through a series of testing methods to ensure that they can effectively prevent water penetration in humid or water-immersed environments.
[0003] However, in existing technologies, waterproof performance testing is mainly conducted on-site after the polyurethane panels have been installed, by directly spraying water on the surface of the panels. This involves uniformly spraying water onto the surface of the panels over a certain period of time and observing whether there are signs of water seepage on the back or inside of the panels. The water spraying equipment used on-site, such as nozzles or water pipes, is prone to problems such as nozzle blockage, unstable water pressure, and uneven nozzle distribution, which can lead to uneven water flow on the surface of the panels. Excessive water flow in some areas may cause over-testing in those areas, while insufficient water flow may fail to adequately detect potential waterproof problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that the water flow is unevenly distributed on the surface of the board, and that excessive water flow in some areas may cause over-detection in those areas, while insufficient water flow may fail to detect potential waterproofing problems. Therefore, a waterproofing detection device for polyurethane boards is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyurethane board waterproof testing device, comprising a water tank, a bellows, and a support platform. A fan is rotatably connected inside the bellows. A support plate is fixedly connected to the bottom of the water tank. A positioning frame is fixedly installed on the upper surface of the support plate. One end of the support platform is slidably connected inside the positioning frame. The bellows is fixedly installed on one side of the water tank support and is located between the water tank and the support platform.
[0006] Preferably, one end of the fan is fixedly connected to a belt drive assembly, and the drive shaft of the belt drive assembly is rotatably mounted on the bottom of the water tank bracket.
[0007] Preferably, a water pump is fixedly connected to the top of the water tank, and the other end of the water pump is connected to a water pump.
[0008] Preferably, the outlet of the water pump is connected to an annular pipe, which is fixedly installed on the inner wall of the air box.
[0009] Preferably, the annular pipe has water nozzles connected at equal intervals on its wall.
[0010] Preferably, the inner side of the positioning frame is provided with a receiving groove, and the end of the support platform is rotatably connected to a slider, which is slidably connected to the inner side of the receiving groove.
[0011] Preferably, a rocker arm is rotatably connected to one side of the support platform, and a notch is provided in the middle section of the positioning frame.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, a wind box is set up to blow water evenly onto the polyurethane board. In actual use, the rotation of the fan can fully agitate the water, thereby ensuring that the sprayed water will come into contact with the polyurethane board in a wide range of mist, solving the problem of uneven water distribution on the board surface, thus ensuring the accuracy of the test results. At the same time, a support plate is set up to determine the position of the board, which can ensure the stability of the board during the test.
[0014] 2. In this utility model, by setting a rocker arm on the side of the support platform, the angle of the support platform can be changed by the rocker arm during actual use, so as to ensure that every part of the polyurethane board can come into contact with water, prevent dead corners, and adjust the angle so that water can flow evenly to all parts of the polyurethane board.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a polyurethane board waterproof testing device, including a water tank 1, a bellows 2, and a support platform 5. A fan 11 is rotatably connected inside the bellows 2. A support plate 3 is fixedly connected to the bottom of the water tank 1. A positioning frame 4 is fixedly installed on the upper surface of the support plate 3. One end of the support platform 5 is slidably connected inside the positioning frame 4. The bellows 2 is fixedly installed on one side of the support of the water tank 1. The bellows 2 is located between the water tank 1 and the support platform 5. A belt drive assembly 8 is fixedly connected to one end of the fan 11. The drive shaft of the belt drive assembly 8 is rotatably installed at the bottom of the support of the water tank 1. A water pump 12 is fixedly connected to the top of the water tank 1. The other end of the water pump 12 is connected to a water pump 7. The outlet of the water pump 7 is connected to an annular pipe 9. The annular pipe 9 is fixedly installed on the inner wall of the bellows 2. Spray nozzles 10 are connected at equal intervals on the pipe wall of the annular pipe 9.
[0023] The specific settings and functions of this embodiment are described below. In actual use, the drive shaft of the belt drive assembly 8 is connected to an external power device. The water tank 1 contains water. When conducting waterproof performance testing, the polyurethane board to be tested is fixed on the support platform 5. Then, the angle of the support platform 5 is adjusted so that one side of the polyurethane board is aligned with the outlet of the air box 2. At this time, the water pump 7 and the power device driving the belt drive assembly 8 are started. The water pump 7 draws water from the water tank 1 through the water pipe 12, transports it to the annular pipe 9, and sprays it out from the spray nozzle 10. The belt drive assembly 8 drives the fan 11. The rotation of the fan 11 will agitate and generate airflow. During the airflow, the water sprayed from the spray nozzle 10 will be blown onto the surface of the polyurethane board, thereby completing the waterproof performance test of the polyurethane board. The rotation of the fan 11 can fully agitate the water, thereby ensuring that the sprayed water will contact the polyurethane board in a large-scale mist, solving the problem of uneven water distribution on the board surface. During the testing process, the angle of the support platform 5 can be continuously adjusted to ensure that the water can be evenly distributed on the polyurethane board.
[0024] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the positioning frame 4 has an inner receiving groove 14, the end of the support platform 5 is rotatably connected to a slider 13, the slider 13 is slidably connected to the inner side of the receiving groove 14, the support platform 5 is rotatably connected to a rocker arm 6, and the middle section of the positioning frame 4 has a notch 15.
[0025] The overall effect of this embodiment is that the upper surface of the support plate 3 is equipped with a bearing seat to determine the position of the rocker arm 6. When adjusting the angle of the support platform 5, one end of the rocker arm 6 is first connected to an external power device. This power device drives the support platform 5 through the rocker arm 6. However, since one end of the support platform 5 is slidably connected to the receiving groove 14 inside the positioning frame 4 through the slider 13, one end of the support platform 5 is always located in the receiving groove 14. This allows the rotation of the rocker arm 6 to change the angle of the support platform 5, ensuring that every part of the polyurethane board can come into contact with water, preventing dead corners, and adjusting the angle allows water to flow evenly to all parts of the polyurethane board.
[0026] The usage and working principle of this device are as follows: Before use, connect the drive shaft of the belt drive assembly 8 and one end of the rocker arm 6 to the external power equipment. Fill the water tank 1 with water and fix the polyurethane board to be tested onto the support platform 5. Then, start the power equipment and the water pump 7. The water pump 7 draws water from the water tank 1 through the water pipe 12, delivers it to the annular pipe 9, and sprays it out from the spray nozzle 10. The belt drive assembly 8 drives the fan 11. The rotation of the fan 11 will agitate and generate airflow. During the airflow, the water sprayed from the spray nozzle 10 will be blown onto the surface of the polyurethane board. The rotation of the rocker arm 6 will change the angle of the support platform 5 to ensure that every part of the polyurethane board can come into contact with water. The change in angle allows the water to flow evenly to all parts of the polyurethane board. The waterproof performance of the polyurethane board is tested by observing whether there are signs of water seepage on the back or inside of the board.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
