Description

Technical Field

[0001] This utility model relates to the field of environmental simulation technology, and in particular to an environmental simulation chamber. Background Technology

[0002] Environmental simulation chambers, also known as artificial climate chambers or environmental test chambers, are key infrastructure in modern scientific research and industrial development. Their core value lies in using controlled artificial means to reproduce, predict, and optimize the performance and reliability of test objects in complex real-world environments. As a consensus in the industry states, environmental simulation chambers are "powerful tools for humans to extend their perception and capabilities, explore the laws of nature, and create high-quality products that are better adapted to and transform the natural world." They are widely used in aerospace, automotive, electronics, biological breeding, and materials science fields for stress screening and accelerated life testing under various environmental conditions, including high and low temperatures, humidity, sunlight, rain, and snowfall.

[0003] To achieve the aforementioned complex environmental simulation functions, a typical comprehensive environmental simulation chamber needs to integrate various physical devices with different functions within a limited chamber space. Among them, rain and snow pipelines for simulating precipitation, and lighting equipment for simulating solar radiation, are key subsystems constituting the simulation of real climate conditions. Currently, the industry practice is to centrally deploy these pipelines and equipment in the top space of the environmental simulation chamber.

[0004] However, while this centralized, rooftop layout effectively utilizes the internal space and avoids interference with the ground testing area, in actual use and maintenance, because all equipment is densely installed in the same area on the roof, maintenance of any subsystem (e.g., replacing a broken light bulb) is inevitably obstructed by the space of surrounding equipment. Within the confined rooftop space, maintenance tools, disassembled parts, or personnel are highly susceptible to accidental collisions with adjacent equipment that they would not otherwise need to handle. For example, when repairing rain pipe joints, a wrench might damage nearby lighting equipment cables or reflectors; when clearing snow pipes, a person might accidentally crush a light fixture. This mutual interference during maintenance directly leads to a high risk of secondary damage and increases unnecessary maintenance costs.

[0005] Therefore, there is an urgent need for an easy-to-maintain environmental simulation chamber. Utility Model Content

[0021] 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.

[0022] The purpose of this invention is to provide an environmental simulation chamber to solve the problems existing in the prior art. By placing the light source outside the chamber, the maintenance difficulty is reduced.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figure 1 - Figure 4 This embodiment provides an environmental simulation chamber, including: a chamber body, a top plate 1 with a light-transmitting part 2, a light source 3 on the upper side of the top plate 1, the light source 3 being correspondingly arranged with the light-transmitting part 2, and snowfall pipes and rainfall pipes being arranged inside the chamber body, which are used to simulate snowfall and rainfall respectively. Its working principle is as follows: the chamber body is used to isolate the internal and external environments; the light source 3 is correspondingly arranged with the light-transmitting part 2, and the light emitted by the light source 3 can illuminate the interior of the chamber to simulate a lighting environment; the snowfall pipes can simulate snowfall; and the rainfall pipes can simulate rainfall. Placing the light source 3 on the upper side of the top plate 1 reduces the integration density of the subsystems, avoids mutual interference between the light source 3, the snowfall pipes, and the rainfall pipes during maintenance, provides sufficient operating space for maintenance workers, greatly reduces maintenance difficulty, and also avoids the problem of bumping into surrounding equipment during maintenance; furthermore, the above installation method can also avoid installation conflicts between subsystems, making the arrangement of various structures more flexible.

[0025] As an example, the light source 3 is a lamp.

[0026] As one embodiment, the environmental simulation chamber also includes a light stand 4, which is detachably connected to the top plate 1. Illuminators are mounted on the light stand 4 and oriented towards the light-transmitting portion 2. The light stand 4 can accommodate multiple illuminations at once. During installation, the illuminations and light stand 4 can be assembled on flat ground first, and then multiple illuminations can be installed onto their corresponding positions on the top plate 1 using the light stand 4. Similarly, multiple illuminations can be removed from the top plate 1 at once using the light stand 4, and then replaced or cleaned on flat ground.

[0027] As one embodiment, the lighting lamp and the light-transmitting part 2 are arranged at intervals along the vertical direction. This arrangement can effectively prevent the lighting lamp and the light-transmitting part 2 from colliding when the lamp holder 4 is disassembled or assembled.

[0028] As one embodiment, the distance between the light source and the light-transmitting part 2 is 0.5 cm to 1 cm.

[0029] As one embodiment, the snowfall pipeline includes a first main pipe 5 and snowfall nozzles 6. The first main pipe 5 is connected to a first water supply device and is installed on the lower side of the top plate 1. The snowfall nozzles 6 are connected to the first main pipe 5, and the first main pipe 5 and the light-transmitting part 2 are arranged alternately. In use, the water supplied by the first water supply device reaches the snowfall nozzles 6 through the first main pipe 5 and is sprayed into the interior of the chamber by the snowfall nozzles 6. Under the low temperature conditions inside the chamber, the sprayed water droplets can quickly crystallize to form snowflakes. The arrangement of the first main pipe 5 on the lower side of the top plate 1 and its alternate arrangement with the light-transmitting part 2 avoids the first main pipe 5 from blocking the light emitted by the light source 3.

[0030] It is understandable that the environmental simulation chamber is also equipped with existing structures such as temperature regulation devices and temperature measurement devices to meet people's needs for using the environmental simulation chamber, which will not be elaborated here.

[0031] As one embodiment, the snowfall pipeline also includes a vertically arranged first branch pipe 7, the upper end of which is connected to the first main pipe 5, and a snowfall nozzle 6 installed at the lower end of the first branch pipe 7. The first branch pipe 7 allows the snowfall nozzle 6 to be set to a suitable spraying height to improve the uniformity of snowflakes.

[0032] In one embodiment, the rainfall pipeline includes a second main pipe 8 and rainfall nozzles 9. The second main pipe 8 is connected to a second water supply device and is installed on the lower side of the top plate 1. The rainfall nozzles 9 are connected to the second main pipe 8, and the second main pipe 8 is staggered with the light-transmitting part 2. In use, the water supplied by the second water supply device reaches the rainfall nozzles 9 through the second main pipe 8 and is sprayed into the interior of the chamber by the rainfall nozzles 9 to simulate rainfall. The arrangement of the second main pipe 8 on the lower side of the top plate 1 and its staggered arrangement with the light-transmitting part 2 avoids the second main pipe 8 from blocking the light emitted by the light source 3.

[0033] As one embodiment, the rain pipeline also includes a vertically arranged second branch pipe 10, the upper end of which is connected to the second main pipe 8, and the rain nozzle 9 is installed at the lower end of the second branch pipe 10. The second branch pipe 10 allows the rain nozzle 9 to be set to a suitable spraying height to improve the uniformity of raindrops.

[0034] In one embodiment, at least two second branch pipes 10 are provided around any one of the first branch pipes 7. The second branch pipes 10 are evenly distributed around the first branch pipe 7, and the spraying direction of the rain nozzles 9 is directed away from the axis of the first branch pipe 7. This arrangement allows multiple rain nozzles 9 and snow nozzles 6 to be grouped together for convenient centralized maintenance or replacement.

[0035] Understandably, the first branch pipe 7 and the second branch pipe 10 bring together the snowfall nozzle 6 and the rainfall nozzle 9, involving only a few pipes and a few nozzles. The degree of concentration is far lower than when all subsystems are integrated together. Therefore, there will be no problem of mutual interference affecting maintenance.

[0036] As one embodiment, the axis of the rain nozzle 9 is inclined downward in a direction away from the first branch pipe 7.

[0037] As one embodiment, the environmental simulation chamber also includes an air supply pipeline 13, and the snowfall nozzle 6 is a two-phase flow nozzle. The first interface of the two-phase flow nozzle is connected to the first main pipe 5, and the second interface of the two-phase flow nozzle is connected to the air supply pipeline 13. The two-phase flow nozzle utilizes high-speed flowing compressed gas to generate strong shear force on low-speed flowing liquid, tearing the liquid into micron-sized droplets, thus ensuring the generation of snowflakes.

[0038] As one embodiment, the upstream end of the gas supply line 13 is connected to a gas source.

[0039] In one embodiment, the gas supply pipeline 13 is connected to the first main pipe 5, and a first valve 11 is provided between the gas supply pipeline 13 and the first main pipe 5. During simulated snowfall, the first valve 11 is closed, and the first water supply device is connected to the snowfall nozzle 6 through the first main pipe 5. The gas supply pipeline 13 is also connected to the snowfall nozzle 6, thereby spraying fine water droplets. The water droplets generate snowflakes in the low-temperature environment to create a snowfall environment. After the simulated snowfall process ends, the first valve 11 is opened, and the gas supply pipeline 13 is connected to the first main pipe 5 through the first valve 11. The high-pressure gas provided by the gas supply pipeline 13 can blow out the residual water in the water circuit, thereby avoiding the problem of residual water freezing and clogging the pipeline at low temperatures.

[0040] As an example, a shut-off valve is provided between the air supply line 13 and the snow spray nozzle 6. The shut-off valve opens during snowfall and closes when the line is being purged, so as to ensure that more gas is used to purge residual water.

[0041] As an example, the first main pipe 5 is provided with a first connection port at the starting end inside the chamber. The air supply pipe 13 is connected to the first main pipe 5 through the first connection port to ensure that there is no residual water in the part of the first main pipe 5 inside the chamber.

[0042] As one embodiment, the portion of the first main pipe 5 located outside the chamber is provided with a shut-off valve for controlling the on / off state of the first main pipe 5.

[0043] In one embodiment, the gas supply line 13 is connected to the second main line 8, and a second valve 12 is provided between the gas supply line 13 and the second main line 8. During the simulated rainfall, the second valve 12 is in a closed state. After the simulated rainfall ends and before the snowfall simulation process is prepared, the second valve 12 is opened, and the gas supply line 13 can blow out the residual water in the second main line 8 to prevent the second main line 8 from being blocked.

[0044] As an example, the second main pipe 8 is provided with a second connection port at the starting end inside the chamber. The air supply pipe 13 is connected to the second main pipe 8 through the second connection port to ensure that there is no residual water in the part of the second main pipe 8 inside the chamber.

[0045] As one embodiment, the portion of the second main pipe 8 located outside the chamber is provided with a shut-off valve for controlling the on / off state of the second main pipe 8.

[0046] As one embodiment, both the first water supply device and the second water supply device are equipped with pressure devices, which can supply water to the first main pipe 5 and the second main pipe 8 at a certain pressure. The pressure device can be existing equipment such as a pressure pump.

[0047] As one embodiment, the gas supply line 13 includes a main line directly connected to the gas source and a branch line for direct connection to the snow spray nozzle 6.

[0048] As one embodiment, the light-transmitting part 2 is a high-transmittance glass installed on the top plate 1.

[0049] As one embodiment, the first main pipe is installed 20 cm below the top plate 1, and the second main pipe is installed 20 cm below the first main pipe.

[0050] As one embodiment, along the axial direction of the first main pipe, a plurality of first connecting pipes are connected to the first main pipe, and a plurality of first branch pipes 7 are connected along the axial direction of the first connecting pipes. Furthermore, the snow sprinkler head 6 adopts a 5-inch... The uniform arrangement of 5.

[0051] As one embodiment, multiple second connecting pipes are connected to the second main pipe along its axial direction, and multiple second branch pipes 10 are connected to the second connecting pipes along their axial direction. Furthermore, the snow sprinkler head 6 adopts a 3... 4. Uniform arrangement.

[0052] As one example, the light source is a full-spectrum lamp.
