Description

Technical Field

[0001] This utility model relates to the field of louver production technology, and in particular to a louver waterproof testing device. Background Technology

[0002] In existing technologies, some equipment that must be enclosed for safety, especially those used in harsh weather and desert regions such as energy storage containers, photovoltaic inverters, box-type transformers, and mobile power vehicles, must dissipate heat through ventilation. Therefore, louvers are often installed to achieve heat dissipation. However, such equipment has relatively high requirements for the ventilation louvers, with waterproof performance testing being particularly important.

[0003] Chinese patent (patent application number 202411469276.4) discloses a "Marine Weatherproof Louver Device and Control Method," in which electrically controlled louvers are installed facing outwards from the cabin ventilation and heat dissipation vents, and leak-detection louvers are installed facing inwards. Water-pressure-reducing and dust-proof cotton is placed between the leak-detection louvers and the electrically controlled louvers to form a weatherproof louver device. A leak detection module is connected to a leak detection cable inside the leak-detection louver and a PLC module of the electric control system. The PLC module is connected to a temperature measuring instrument inside the cabin and, through sensors and actuators, to the electrically controlled louvers. In addition to conventional rainproof and heat dissipation functions, this marine weatherproof louver device and control method also includes dustproofing, control of louver opening airflow, drainage outlets, leak detection alarms, temperature detection, and detachable maintenance, effectively improving the airflow of the cabin louver openings and preventing risks from water ingress and excessive temperature.

[0004] Another Chinese patent (patent application number 201921400878.9) discloses a "Venetian blind performance testing device," which includes an environmental chamber and a rainwater collection and measurement device. The rainwater collection and measurement device includes a rainwater collection tank and a weighing system. The environmental chamber includes a rain outlet, and the rainwater collection tank includes an inlet and an outlet. The environmental chamber and the rainwater collection tank are adjacent to each other with a gap. The rain outlet is adjacent to the inlet, and the gap is used to accommodate the venetian blind to be tested. The venetian blind to be tested is located between the rain outlet and the inlet. The weighing system includes a weighing instrument and a collection container, which is connectable to and disconnectable from the outlet. The weighing instrument is used to weigh the rainwater flowing into the collection container within a preset time. This venetian blind performance testing device uses a weighing sensor to weigh the rainwater over a certain period of time to determine the rainwater flow rate, which offers higher accuracy compared to flow meter measurement.

[0029] Example:

[0030] The waterproof testing device for venetian blinds in this embodiment consists of a water tank 2, a test chamber assembly, a spray assembly, and an intelligent control assembly. The test chamber assembly is located on top of the water tank 2, the spray assembly is located on top of the water tank 2 and around the test chamber assembly, and the intelligent control assembly is located on top of the water tank 2 and on one side of the test chamber assembly.

[0031] Water tank 2 is an open-top box with a rectangular cross-section (i.e., an open-top bucket with a rectangular cross-section, or an open-top bucket with a square cross-section). Two or more (five in this example) longitudinal beams 24 are provided on its open end face for installing the test box. Movable casters 1 (heavy-duty casters are used in this example) are also provided at the four corners of the bottom of water tank 2.

[0032] The test chamber assembly consists of a test chamber body and a negative pressure generating component.

[0033] The test chamber is composed of a test chamber frame 5, a left side test frame plate 7, two front and rear side test frame plates 10, one or more (three in this example) left side test mounting frames 4, two or more (eight in this example, four in the front and four in the back) front and rear side test mounting frames 13, one or more quick clamps 6, a test chamber observation door 17 (with an observation window 18), and a test chamber bottom plate 27 (with a water return hole 26).

[0034] The left side test frame plate 7 (with multiple left side louver test mounting holes 15, three in this example), the front and rear side test frame plates 10 (divided into front and rear pieces, each with multiple front and rear side louver test mounting holes 11, four in this example), the test chamber observation door 17, and the test chamber bottom plate 27 are respectively located on the left side, front and rear sides, right side, and bottom of the test chamber frame 5.

[0035] The left side test mounting frame 4 (three in this example, but one or two can also be used, mainly for testing relatively small louvers) and the front and rear side test mounting frames 13 (four in this example, but one, two, four or more can also be used, mainly for testing relatively large louvers) are respectively mounted on the left side test frame plate 7 and the front and rear side test frame plates 10 (two pieces). Simultaneously, multiple quick clamps 6 (commercially available) are also installed on the left side test frame plate 7 and the front and rear side test frame plates 10 around the left side test mounting frame 4 and the front and rear side test frame plates 13, respectively, for quickly clamping the louvers to be tested. The joints between the left side test mounting frame 4 and the front and rear side test mounting frames 13 and the left side test frame plate 7 and the front and rear side test frame plates 10 are all sealed with sealant to prevent water from seeping into the inner cavity of the test chamber during operation.

[0036] The negative pressure generating component consists of a suction hood 14 and one or more suction fans 12 (the specific number corresponds to the number of front and rear side test mounting frames 13 set on one side of the front and rear side test frame plate 10, which is four in this example). The suction hood 14 is set on top of the test box frame 5 (forming a closed test box), and the suction fans 12 are evenly arranged on top of the suction hood 14.

[0037] The spray assembly consists of a spray pipe support 3, a spray pipe 9, one or more nozzles 8, a water pump 25, a flow regulating valve 23, a pressure regulating valve 22, a pressure gauge 21, and a flow meter 19.

[0038] The sprinkler pipe support 3 is supported by the upper ends of multiple columns installed around the water tank 2. It is formed by a frame strip, the height of which corresponds to the upper part of the test chamber, and the spray section of the spray pipe 9 is placed in... The water pump 25 is submerged in the water inside the water tank 2, and its output end is connected to the input end of the spray pipe 9. The flow regulating valve 23 and the pressure regulating valve 22 are connected in sequence from the water pump 25 to the input end of the spray pipe 9. The nozzle 8 is connected to the spray section of the spray pipe 9 through a steel wire hose (its angle and direction can be adjusted arbitrarily). Each nozzle 8 corresponds to a test installation frame (i.e., a louver to be tested). The pressure gauge 21 and the flow meter 19 are both in the intelligent control component. The pressure gauge 21 is connected to the pressure regulating valve 22 through a water pipe to the input end of the spray pipe 9. The flow meter 19 is connected to the flow regulating valve 23 and the pressure regulating valve 22 through a water pipe. The two are used to regulate the flow rate and pressure of the water in the spray pipe 9, respectively.

[0039] The intelligent control component consists of an intelligent control box 20 and an intelligent control panel mounting plate 16. The intelligent control box mounting plate 16 is located on the rear right side of the test chamber, and the intelligent control box 20, pressure gauge 21, and flow meter 19 are mounted on it. The intelligent control box 20 contains a PLC programmable controller component, and its panel is equipped with a touch screen. The flow regulating valve 23, pressure regulating valve 22, water pump 25, and suction fan 12 are connected to the PLC programmable controller component of the intelligent control box 20 via control lines. By operating the touch screen, the working time of the water spraying and suction equipment, as well as the flow rate and pressure of the water in the spray pipe 9, can be set, and one-button start can be achieved to complete the test.

[0040] Before use, select the appropriate left side test frame plate 7, front and rear side test frame plate 10, left side test mounting frame 4, and front and rear side test mounting frame 13 according to the size and specifications of the louvers to be tested; then, fix the louvers to be tested in the left side louver test mounting hole 15 and the front and rear side louver test mounting hole 11 with quick clips 6; next, inject the clean water (ordinary water) used for testing into the water tank 2, and then connect the power input line of the intelligent control box 20 to the mains power; then, input the parameter values ​​required for testing (such as the flow rate and pressure of water in the spray pipe 9, the working time of the water pump 25 and the suction fan 12, etc.) through the touch screen on the intelligent control box 20.

[0041] During use, press the start / stop switch on the touchscreen of the intelligent control box 20. The PLC programmable controller component inside the intelligent control box 20 will then start the suction fan 12, drawing air out of the test chamber and creating a negative pressure state inside the chamber (simulating the use of louvers). This allows air from outside the test chamber to flow into the chamber through the louvers being tested, forming a cooling circulation airflow. During this process, carefully listen for any abnormal noises inside the test chamber. If vibration noise is present, it indicates that some or all of the louvers being tested have assembly quality problems, meaning that the slats of the louvers being tested are not securely installed and need to be reassembled.

[0042] The air test duration is generally controlled within 10-20 minutes. Afterwards, the PLC programmable controller in the intelligent control screen 20 starts the water pump 25 (while the suction fan 12 continues to operate until the test is complete). The test water drawn by the pump 25 passes through the flow regulating valve 23 and the pressure regulating valve 22 to control the flow and pressure respectively, and is then input into the spray pipe 9. It is then sprayed through each nozzle 8 onto the front of the corresponding louver to be tested. Although the inner cavity of the test chamber is still under negative pressure, under normal circumstances, the water sprayed onto the front of the louver to be tested will flow down the surface of the louver into the water tank 2, forming a cycle. Therefore, through the observation window 18, it can be seen that the inner cavity of the test chamber remains dry, indicating that the waterproof performance of these louvers to be tested is good and meets the product quality requirements. However, if the waterproof performance of the louvers to be tested does not meet the requirements, some water will seep into the inner cavity of the test chamber, forming obvious water stains. This can be observed and confirmed through the observation window 18.

[0043] The water spray test duration is generally controlled within 10-30 minutes. Then, the PLC programmable controller component in the intelligent control screen 20 shuts off the water pump 25, while the suction fan 12 continues to work for 10-20 minutes. The purpose is mainly to dry the surface moisture of the louvers to be tested, eliminating the need for a subsequent drying process. If a dedicated drying device is set up to speed up the test and the suction fan 12 and water pump 25 are shut off simultaneously, the test of this batch of louver products is then completed.

[0044] If water seeps into the inner cavity of the test chamber during the testing process, the seeped water will flow back into the water tank 2 through the return water hole 26.

[0045] During the water spraying test, the flow rate and pressure of the water in the spray pipe 9 are displayed in real time on the pressure gauge 21 and the flow meter 19. When the flow rate and pressure of the water in the spray pipe 9 exceed the preset parameter values, the PLC programmable controller component in the intelligent control screen 20 immediately adjusts the flow rate and pressure of the water in the spray pipe 9 through the flow regulating valve 23 and the pressure regulating valve 22.

[0046] By selecting left-side test frame plate 7, front and rear side test frame plate 10 (i.e., front and rear side louver test installation hole 11) of different sizes (i.e., the size of the left-side louver test installation hole 15), and matching left-side test installation frame 4 and front and rear side test installation frame 13, louvers of different sizes and specifications can be tested.

[0047] This utility model relates to a waterproof testing device for louvers, which is suitable for testing various louvers that require waterproof performance.
