[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 In this embodiment of the utility model, a spray device for testing the waterproof sealing of a cabinet includes a frame body 1. The bottom of the frame body 1 is fixed on a grid pad 5. A circulating water tank 7 is provided below the grid pad 5, and a filter screen 6 is provided between the circulating water tank 7 and the grid pad 5. Multiple spray pipes 2 are arranged inside the frame body 1, and multiple nozzles 4 are connected in series on the spray pipes 2. The multiple spray pipes 2 are connected to a main pipe 3, and the other end of the main pipe 3 extends into the circulating water tank 7 and is connected to a water pump in the circulating water tank 7.
[0028] By adopting the above technical solution, when in use, the water pump in the circulating water tank 7 pumps out water, and then disperses the water into each spray pipe 2 through the main pipe 3, and then conducts a water spray test on the cabinet through the nozzle 4.
[0029] Nozzles 4 are distributed on both sides, top, and diagonally above the cabinet, spraying water onto the top and sides of the cabinet to ensure uniform spraying of all parts, effectively simulating a real rainfall environment and improving test accuracy. The sprayed water flows back to the circulating water tank 7 through the grid plate 5, achieving water resource recycling, which is environmentally friendly and efficient. Simultaneously, the device is equipped with protective glass 8 to prevent water splashing out; the filter plate 6 filters the sprayed water, preventing impurities from entering the circulating water tank 7 and ensuring water quality.
[0030] This compact device requires minimal space, making it easy to install and move within a laboratory. It is compatible with various rack sizes, simple to operate, and has low maintenance costs, significantly improving the efficiency of waterproofing tests. Furthermore, it features a water recycling function, effectively solving the problems of waterproofing and wastewater treatment required in existing water spray tests.
[0031] In this embodiment, the top and sides of the frame 1 are fitted with protective glass 8, and one end of the frame 1 has a window for easy access to the cabinet; the window can also be fitted with a double-leaf glass door. This prevents water from splashing during water spray testing and ensures that the water flows into the circulating water tank 7 for easy recycling.
[0032] In this embodiment, the filter screen 6 is inserted into the profile frame 9 on both sides; the two profile frames 9 are symmetrically arranged and fixed above the circulating water tank 7.
[0033] By adopting the above technical solution, the filter screen 6 and the profile frame 9 are fixed by snap-fit, ensuring that they are not easily moved under the impact of water flow, while also being easy to disassemble and clean, and convenient to maintain.
[0034] In this embodiment, each profile frame 9 has multiple connecting blocks 15 bolted to its upper end; the multiple connecting blocks 15 are arranged in a straight line and fixed to the bottom of the grille pad 5 with bolts. The design of the connecting blocks 15 enhances the stability of the overall structure and provides sufficient space between the grille pad 5 and the filter screen 6 to install the rodless cylinder 10, ensuring that the rodless cylinder 10 drives the platform 13.
[0035] In this embodiment, the grid pad 5 has a solid plate area in the middle, and its periphery is arranged in a grid shape; a strip groove is opened in the solid plate area, and two slide rails 11 are fixed above it; a platform 13 is provided above the slide rails 11; the bottom of the platform 13 is slidably connected to the slide rails 11 through a slide block 12.
[0036] More specifically, a rodless cylinder 10 is also fixed to the bottom of the grid pad 5, and the driving part of the rodless cylinder 10 extends through to the top of the strip groove and is fixed to the platform 13.
[0037] By adopting the above technical solution, when conducting water spray testing on the cabinet, the cabinet is first placed on the platform 13, and the rodless cylinder 10 drives the platform 13 to move smoothly along the slide rail 11 so that the cabinet is in the center of the equipment. Then the water spray is turned on to achieve water spray testing on the cabinet.
[0038] In addition, by preventing operators from entering the spray equipment, it is possible to prevent mud carried by their feet from falling into the equipment, thereby ensuring the cleanliness of the water and reducing the equipment's filtration pressure.
[0039] A controller 14 is also fixed on one side of the frame 1. The controller 14 directly controls the start and stop of the pump and is electrically connected to the solenoid valve that controls the rodless cylinder 10 through a wire. The action of the rodless cylinder 10 is achieved by controlling the action of the solenoid valve. This control method is a traditional control method, and its control principle is existing technology, so it will not be described in detail here.
[0040] The working principle of this utility model is as follows: When conducting a water spray test on the cabinet, the cabinet is first placed on the platform 13, and the rodless cylinder 10 drives the platform 13 to move smoothly along the slide rail 11 so that the cabinet is in the center of the equipment, and then the water spray is turned on.
[0041] A water pump in the circulating water tank 7 pumps water out, which is then distributed to various spray pipes 2 through the main pipe 3. The water is then sprayed onto the server rack through nozzles 4. The nozzles 4 are distributed on both sides, top, and slightly above the rack, ensuring uniform spraying of all parts of the rack and effectively simulating a real rainfall environment, thus improving test accuracy. The sprayed water flows back to the circulating water tank 7 through the grid plate 5, achieving water resource recycling, which is environmentally friendly and efficient. Simultaneously, the device is equipped with protective glass 8 to prevent water splashing; the filter screen 6 filters the sprayed water, preventing impurities from entering the circulating water tank 7 and ensuring water quality.
