Description

Technical Field

[0001] This utility model relates to the field of control cabinet manufacturing technology, specifically to a testing device for control cabinet manufacturing. Background Technology

[0002] Control cabinets are enclosed or semi-enclosed enclosures that integrate various electrical control components, instruments, circuits, and auxiliary equipment. They are used for the centralized installation, protection, and management of control devices in fields such as industrial automation, power systems, and communication equipment. Through a rational internal structure layout, they enable the monitoring, regulation, command transmission, and fault handling of equipment operation, while providing basic protection functions. When applied to outdoor scenarios, they enhance weather resistance design based on their original functions, using a high-strength, corrosion-resistant and rust-proof shell, adding waterproof sealing rings and dustproof nets, and equipped with a heat dissipation / insulation system adapted to extreme temperature differences. They can withstand natural corrosion such as rain, snow, ultraviolet rays, and salt spray, and are widely used in outdoor substations, communication base stations, photovoltaic power stations, traffic signal hubs, etc., becoming a key hub for stable connection between outdoor equipment and the control center, ensuring the continuous and reliable operation of the control system in open-air environments.

[0003] In the production process of outdoor control cabinets, rain testing is a crucial step in ensuring their weather resistance. A dedicated rain testing device is needed to simulate natural rainfall and verify the cabinet's sealing performance and structural stability. Current technologies often employ a design that combines a drive component with a water pump and spray pipes. Typically, a motor is installed to rotate the spray pipes to expand the spray coverage area. However, this type of device has significant limitations in practical applications: firstly, the use of a motor significantly increases equipment costs, and motor maintenance also incurs additional expenses and workload; secondly, the rotation trajectory of the spray pipes is mostly a single circular motion, making it difficult to cover the top, sides, and other areas of the cabinet, easily creating spray blind spots, which affects the accuracy of the test results and impacts the efficiency of production testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a testing device for control cabinet production that can achieve multi-angle, wide-range spraying without the need for motor drive, reducing equipment costs and maintenance workload, while improving testing coverage and accuracy. It is also compatible with different cabinet specifications and easy to operate, solving the problems in the background technology of increased costs and cumbersome maintenance due to the use of motors, as well as the dead angles caused by the single spray trajectory, which affect production testing efficiency.

[0005] To achieve the aforementioned goals of multi-angle, wide-range spraying without motor drive, reducing equipment costs and maintenance workload, while improving detection coverage and accuracy, adapting to different cabinet specifications, and facilitating operation, this utility model provides the following technical solution: A detection device for controlling cabinet production, comprising a detection housing, a U-shaped rotating ring rotatably connected to the top of the detection housing, a uniformly distributed inclined plate fixedly connected to the inner cavity of the U-shaped rotating ring, a uniformly distributed spray nozzle penetrating and fixedly connected to the bottom of the U-shaped rotating ring, an installation ring sleeved on the outer wall of the U-shaped rotating ring, and the side of the installation ring away from the U-shaped rotating ring fixedly connected to the detection housing, a uniformly distributed ball bearing rotatably connected to the top of the installation ring, the ball bearing cooperating with the U-shaped rotating ring, a connecting pipe penetrating and fixedly connected to one side of the U-shaped rotating ring, a guide plate fixedly connected to the inner cavity of the side of the connecting pipe penetrating the installation ring, and the guide plate cooperating with the inclined plate.

[0008] As a further improvement of this utility model: the lower two sides of the side of the detection box away from the placement plate are fixedly connected to limit sliders, and the bottom two sides of the inner cavity of the detection box are provided with limit grooves, and the limit sliders slide in the limit grooves.

[0009] As a further improvement of this utility model: the lower two sides of the side of the detection box away from the placement plate are fixedly connected to limit sliders, and the bottom two sides of the inner cavity of the detection box are provided with limit grooves, and the limit sliders slide in the limit grooves.

[0010] As a further improvement of this utility model: both sides of the placement plate are provided with discharge grooves, and the discharge grooves cooperate with the collection grooves.

[0011] As a further improvement of this utility model, rollers are installed through both sides of the bottom of the box door.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, after the water pump is started, the water flow delivered through the suction pipe, connecting pipe two, and connecting pipe one is guided by the guide plate and sprayed obliquely. The impact force generated by the collision with the inclined plate drives the U-shaped rotating ring to rotate naturally. The ball bearings at the top of the ring reduce friction and make its rotation smooth. Finally, the water is sprayed on the top and sides of the cabinet by two sets of inclined nozzles, achieving all-round, no-dead-angle detection and fully simulating natural rainfall. This design uses the kinetic energy of water to drive the rotation, eliminating the need for a motor, reducing costs and maintenance, and providing a wider spraying range.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 7In this embodiment of the present invention, a testing device for control cabinet production includes a testing box 1. A U-shaped rotating ring 2 is rotatably connected to the top of the testing box 1. An evenly distributed inclined plate 3 is fixedly connected to the inner cavity of the U-shaped rotating ring 2. An evenly distributed nozzle 4 is connected through and fixedly connected to the bottom of the U-shaped rotating ring 2. An installation ring 5 is fitted on the outer wall of the U-shaped rotating ring 2, and the side of the installation ring 5 away from the U-shaped rotating ring 2 is fixedly connected to the testing box 1. At this time, the water pump 9 is started, which draws water pre-stored in the collection tank 17 through the suction pipe 18. The water flows through the second connecting pipe 10 to the first connecting pipe 7, and is sprayed obliquely under the guidance of the guide plate 8 fixed in the inner cavity of the first connecting pipe 7. After the sprayed water flow collides with the inclined plate 3, the resulting impact force drives the U-shaped rotating ring 2 to rotate naturally. An evenly distributed ball bearing 6 is rotatably connected to the top of the installation ring 5. The ball bearing 6 at the top of ring 5 further reduces the frictional resistance of the U-shaped rotating ring 2 during rotation, making its rotation process smoother and more stable. The ball bearing 6 cooperates with the U-shaped rotating ring 2. A connecting pipe 7 is connected through and fixedly connected to one side of the U-shaped rotating ring 2. A guide plate 8 is fixedly connected to the inner cavity of one side of ring 5 through the connecting pipe 7. The guide plate 8 cooperates with the inclined plate 3. A water pump 9 is installed on the lower part of one side of the outer wall of the detection box 1. A connecting pipe 10 is installed on the top side of the water pump 9. The side of the connecting pipe 10 away from the water pump 9 is fixedly connected to the connecting pipe 7. Then, the water flows into the U-shaped rotating ring 2 and is finally discharged through two sets of inclined nozzles 4: one set of nozzles 4 sprays the top of the control cabinet, and the other set accurately covers the side of the cabinet, realizing all-round, no dead angle rain detection of the cabinet, fully simulating the natural rainfall environment.

[0024] A control valve 11 is installed in the middle of the connecting pipe 2 10. The control valve 11 is equipped with a manual adjustment knob and scale markings. By rotating the knob, the operator can intuitively and accurately control the water flow speed in the connecting pipe 2 10 according to the scale markings, and then flexibly adjust the water volume and water pressure sprayed from the nozzle 4. This simulates different rainfall scenarios such as heavy rain and light rain, making the test more in line with the actual natural environment and comprehensively verifying the weather resistance performance of the control cabinet under various rain conditions.

[0025] A door 12 is installed on one side of the testing chamber 1. A placement plate 13 is fixedly connected to the bottom of one side of the U-shaped rotating ring 2. The two sides of the placement plate 13 penetrate the testing chamber 1 and are slidably connected. Limiting sliders 14 are fixedly connected to the lower two sides of the side of the testing chamber 1 away from the placement plate 13. Limiting grooves 15 are opened on both sides of the bottom of the inner cavity of the testing chamber 1, and the limiting sliders 14 slide in the limiting grooves 15. When the door 12 is pulled out, it will simultaneously drive the placement plate 13 to extend outward. The limiting sliders 14 on both sides of the bottom of the placement plate 13 will slide stably in the limiting grooves 15 inside the testing chamber 1, accurately limiting the movement trajectory of the placement plate 13, preventing it from detaching from the testing chamber 1 due to excessive pulling out, and ensuring operational safety.

[0026] A collection trough 17 is provided in the lower part of the inner cavity of the detection box 1. A water suction pipe 18 is connected through and fixedly connected to one side of the inner cavity of the collection trough 17. The water suction pipe 18 also passes through the detection box 1 and is fixedly connected to the water pump 9. Discharge troughs 16 are provided on both sides of the placement plate 13. The discharge troughs 16 cooperate with the collection trough 17. After water spraying, the water will fall onto the placement plate 13 and then fall into the collection trough 17 through the discharge troughs 16 on both sides of the placement plate 13, forming a complete water circulation system. This realizes the recycling of water resources, which saves water costs and improves the environmental friendliness of the equipment.

[0027] Rollers 19 are installed on both sides of the bottom of the cabinet door 12. When the cabinet door 12 is pulled outward, the rollers 19 at the bottom of the door contact the ground and rotate smoothly, which effectively reduces the friction when opening the door and makes the pushing and pulling operation of the cabinet door 12 more effortless and convenient.

[0028] The working principle of this utility model is as follows: When it is necessary to perform rainwater detection on the control cabinet, the cabinet door 12 is first pulled outward. During this process, the roller 19 at the bottom of the door contacts the ground and rotates smoothly, which effectively reduces the friction when opening the door, making the pushing and pulling operation of the cabinet door 12 more effortless and convenient.

[0029] As the cabinet door 12 is pulled out, the placement plate 13 will extend outward simultaneously. The limiting sliders 14 on both sides of the bottom of the placement plate 13 will slide stably in the limiting grooves 15 inside the detection cabinet 1, precisely limiting the movement trajectory of the placement plate 13 and preventing it from detaching from the detection cabinet 1 due to excessive pulling out, thus ensuring operational safety. After being pulled out to the correct position, the control cabinet to be tested will be placed stably in the middle of the top of the placement plate 13. Then, the cabinet door 12 and the placement plate 13 will be pushed into the detection cabinet 1 together to complete the preparation before testing.

[0030] At this time, the water pump 9 is started, which draws water pre-stored in the collection tank 17 through the suction pipe 18. The water flows through the second connecting pipe 10 to the first connecting pipe 7, and is sprayed out obliquely under the guidance of the guide plate 8 fixed in the inner cavity of the first connecting pipe 7. After the sprayed water flow collides with the inclined plate 3, the resulting impact force drives the U-shaped rotating ring 2 to rotate naturally. The ball bearing 6 on the top of the mounting ring 5 further reduces the frictional resistance of the U-shaped rotating ring 2 during rotation, making its rotation process smoother and more stable. Subsequently, the water flow flows into the U-shaped rotating ring 2 and is finally discharged through two sets of inclined nozzles 4: one set of nozzles 4 sprays the top of the control cabinet, and the other set accurately covers the side of the cabinet, realizing all-round, no-dead-angle rain detection of the cabinet, fully simulating the natural rainfall environment;

[0031] It should be noted that a rotary sealing gasket is installed at the connection between the U-shaped rotating ring 2 and the mounting ring 5. This sealing gasket fits tightly against the contact surface of the two, which can not only flexibly adapt to the rotation of the U-shaped rotating ring 2, but also effectively prevent water leakage, ensuring that the water circuit maintains good sealing performance during dynamic operation, and providing a reliable guarantee for the stable operation of the sprinkler system.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
