Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray test chambers, and particularly relates to a tower spray device for a salt spray test chamber. Background Technology

[0002] Salt spray test chambers are mainly used to simulate the corrosive effects of marine or salt spray environments on products, thereby verifying the corrosion resistance of the tested samples. Most existing salt spray test devices use fixed nozzles for spraying. These nozzles spray in a fixed direction, and the distribution of salt spray inside the tower is prone to unevenness, leading to a decrease in the reliability of the test results. At the same time, salt spray needs to be discharged through an exhaust structure during use to ensure a stable test environment. However, the existing exhaust direction is usually fixed and cannot be flexibly adjusted according to the usage environment. This can easily cause residual salt spray to diffuse directly to the operator's location, increasing the risk of inhalation and affecting the safety of the experiment. Utility Model Content

[0003] This utility model provides a tower-type spray device for a salt spray test chamber, aiming to solve the problem that most existing salt spray test devices use fixed nozzles for spraying. These nozzles have a fixed spray direction, and the distribution of salt spray inside the tower is prone to unevenness, which leads to a decrease in the reliability of the test results. At the same time, salt spray needs to be discharged through an exhaust structure during use to ensure a stable test environment. However, the existing exhaust direction is usually fixed and cannot be flexibly adjusted according to the usage environment. This can easily cause the discharged residual salt spray to directly diffuse to the operator's location, increasing the risk of inhalation.

[0004] This utility model is implemented as follows: a tower spray device for a salt spray test chamber includes: a tower body, a salt spray chamber installed on one side of the tower body, a top cover installed on the top of the salt spray chamber, a spraying device installed inside the tower body, and a guide device sleeved on the top cover. The spraying device includes a frame, a vertical plate fixedly connected inside the frame, a water pipe installed inside the frame, a conduit fixedly connected to one end of the water pipe, the conduit installed inside a salt spray chamber, a swing pipe installed inside the water pipe, the swing pipe rotatably connected inside the frame, a drive motor fixedly connected to one side of the vertical plate, a rotating shaft installed at the output end of the drive motor, the rotating shaft rotatably connected inside the vertical plate, a rotating plate installed at one end of the rotating shaft, a linkage rod rotatably connected to the outside of the rotating plate via a rotating shaft, and a drive plate rotatably connected to the outside of the linkage rod via a rotating shaft.

[0005] Preferably, a connecting plate is fixedly connected to the outside of the frame, and the connecting plate is fixedly connected to the inside of the tower.

[0006] Preferably, the swing tube is installed inside the drive plate, and the upper part of the swing tube is rotatably connected to the vertical plate via a rotating shaft.

[0007] Preferably, the guiding device includes a collar and a guide tube, the collar being sleeved on the outside of the top cover, the guide tube being installed above the top cover, and a locking plate being installed outside the collar.

[0008] Preferably, a connecting ring is installed inside the locking plate, and a slot is formed inside the connecting ring.

[0009] Preferably, the gap between the connecting ring and the collar forms a groove, and a slider is slidably connected in the groove, the slider being fixedly connected to the outside of the guide tube.

[0010] Preferably, the size of the slot is larger than the size of the slider, and the slider is slidably connected within the slot.

[0011] Compared with related technologies, the tower spray device for a salt spray test chamber provided by this utility model has the following beneficial effects: 1. In this utility model, through the setting of the spraying device, the salt mist enters the water pipe and the swing pipe through the pipeline, and is sprayed out from the nozzle in the swing pipe. When the drive motor starts, the motor drives the rotating shaft to rotate. When the rotating shaft rotates, it pushes the rotating plate to rotate synchronously. The rotating plate drives the linkage rod to move through the rotating shaft. The linkage rod then drives the drive plate to swing through the rotating shaft. When the drive plate swings back and forth, it can drive the swing pipe to swing in the frame, so that the nozzle swings back and forth in the tower body, ensuring that the salt mist is sprayed evenly in the tower body and improving the uniformity and reliability of the test.

[0012] 2. In this utility model, through the setting of the guide device, the guide tube drives the slider to insert into the slot of the connecting ring. Then, when the guide tube rotates, it drives the slider to slide in the groove between the collar and the connecting ring, thereby realizing the adjustment of the direction of the guide tube. This allows the exhaust direction to be flexibly changed as needed, preventing the exhaust residual salt mist from rushing directly towards the operator, effectively reducing the risk of the human body inhaling residual smoke, and improving the safety of the device.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0015] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] This utility model embodiment provides a tower-type spray device for a salt spray test chamber, such as... Figures 1-5 As shown, it includes a tower body 1, a salt spray box 2 installed on one side of the tower body 1, a top cover 3 installed on the top of the salt spray box 2, a spraying device 4 installed inside the tower body 1, and a guide device 5 fitted on the top cover 3. The spraying device 4 includes a frame 402, a vertical plate 403 fixedly connected inside the frame 402, a water pipe 405 installed inside the frame 402, a pipe 404 fixedly connected to one end of the water pipe 405, the pipe 404 installed inside the salt spray chamber 2, a swing pipe 411 installed inside the water pipe 405, the swing pipe 411 rotatably connected inside the frame 402, a drive motor 406 fixedly connected to one side of the vertical plate 403, a rotating shaft 407 installed at the output end of the drive motor 406, the rotating shaft 407 rotatably connected inside the vertical plate 403, a rotating plate 408 installed at one end of the rotating shaft 407, a linkage rod 409 rotatably connected to the outside of the rotating plate 408 via a rotating shaft, and a drive plate 410 rotatably connected to the outside of the linkage rod 409 via a rotating shaft.

[0017] In this embodiment, the cooperation between the rotating shaft 407 and the rotating plate 408 enables the rotating plate 408 to move synchronously when the rotating shaft 407 is driven to rotate by the drive motor 406, thereby effectively transmitting the rotational motion to the external linkage rod 409, realizing the transformation from a single rotational action to an outward extension, and providing a power transmission path for the reciprocating swing of the subsequent drive plate 410.

[0018] In a further preferred embodiment of the present invention, a connecting plate 401 is fixedly connected to the outside of the frame 402, the connecting plate 401 is fixedly connected to the inside of the tower body 1, the swing tube 411 is installed inside the drive plate 410, and the upper part of the swing tube 411 is rotatably connected to the vertical plate 403 through a rotating shaft.

[0019] In this embodiment, the swing tube 411 is installed inside the drive plate 410, so that the drive plate 410 can directly drive the swing tube 411 to follow when swinging, thereby causing the nozzle in the swing tube 411 to reciprocate inside the tower body 1, avoiding the spray from being concentrated in a local area, and achieving uniform diffusion of salt spray in space.

[0020] In a further preferred embodiment of this utility model, the guiding device 5 includes a collar 501 and a guide tube 505. The collar 501 is sleeved on the outside of the top cover 3, and the guide tube 505 is installed above the top cover 3. A locking plate 502 is installed outside the collar 501, and a connecting ring 503 is installed inside the locking plate 502. A slot 504 is formed in the connecting ring 503. The gap between the connecting ring 503 and the collar 501 forms a sliding groove. A slider 506 is slidably connected in the sliding groove. The slider 506 is fixedly connected to the guide tube 505. The size of the slot 504 is larger than the size of the slider 506, and the slider 506 is slidably connected in the slot 504.

[0021] In this embodiment, the slot 504 on the connecting ring 503 provides a defined trajectory for the slider 506, allowing the slider 506 to slide in a controlled manner within the slot 504. This ensures that the guide tube 505 can move freely during adjustment without detaching or deflecting, thus improving the reliability of the exhaust guide. The sliding fit between the groove and the slider 506 allows the slider 506 to reciprocate within a defined gap, thereby driving the guide tube 505 to adjust its position smoothly. Through this limiting guide relationship, smooth movement can be maintained, and structural loosening due to excessive offset can be avoided.

[0022] In summary, through the configuration of the spraying device 4, the salt mist enters the water pipe 405 and the swing pipe 411 via the pipe 404, and is then sprayed out from the nozzle inside the swing pipe 411. When the drive motor 406 starts, the motor drives the rotating shaft 407 to rotate. When the rotating shaft 407 rotates, it pushes the rotating plate 408 to rotate synchronously. The rotating plate 408 drives the linkage rod 409 to move via the rotating shaft. The linkage rod 409 then drives the drive plate 410 to swing via the rotating shaft, so that the reciprocating swing of the drive plate 410 can drive the swing pipe 411. 1. The nozzle swings within the frame 402, causing it to reciprocate within the tower body 1. Through the guide device 5, the guide tube 505 drives the slider 506 to insert into the slot 504 of the connecting ring 503. Subsequently, as the guide tube 505 rotates, it drives the slider 506 to slide in the groove between the collar 501 and the connecting ring 503, thereby adjusting the direction of the guide tube 505. This allows the exhaust direction to be flexibly changed as needed, preventing residual salt spray from directly hitting the operator.
