Description

Technical Field

[0001] This application relates to the technical field of salt spray test chambers, and in particular to a test chamber drainage device. Background Technology

[0002] A salt spray test chamber is a device used for external corrosion testing and is currently an essential testing equipment for some automotive radiator manufacturers. During the external corrosion test, a certain amount of water needs to be placed inside the test chamber to raise the temperature. However, the salt spray test involves spraying salt mist into the chamber, and the accumulation of salt mist increases the water level at the bottom of the chamber. As the salt spray test cycle is relatively long and the spraying time is extended, the water level at the bottom of the chamber gradually rises, submerging the test specimen and affecting the test results. Therefore, it is necessary to drain the accumulated water from the test chamber in a timely manner. To address these issues, this application provides a test chamber drainage device. Utility Model Content

[0003] To address the aforementioned problems, this application provides a test chamber drainage device.

[0004] This application provides a test chamber drainage device, including a panel installed on the bottom plate of the test chamber. A recessed section is provided on the inner side of the panel. A water collection sleeve is provided below the recessed section. After the bottom end of the water collection sleeve is sealed by a rubber plug, a water-containing cavity is formed inside. A float is coaxially provided above the rubber plug. The float will rise under the action of external water accumulation, and the float will rise with it, opening the drainage channel of the water-containing cavity.

[0005] A buoyancy restriction structure is provided below the float.

[0006] By opening a hole at the bottom of the test chamber and installing a sinking section on it, and setting a water collection sleeve below the sinking section, the test chamber can be drained when there is a lot of water inside by using a combination of float and rubber plug. When the water is almost drained, the remaining water can be collected into the water collection sleeve, thereby further reducing the impact on the external environment.

[0007] Preferably, the water collection sleeve includes an internally threaded ring at the top, which is threadedly connected to an externally threaded ring at the bottom of the recessed section to achieve fixation with the panel.

[0008] Preferably, the water-collecting sleeve further includes an annular section in the middle and a drain outlet at the bottom. A second recessed section is connected between the annular section and the drain outlet, and the second recessed section is used for contact sealing with the rubber plug.

[0009] Preferably, a crossbar is welded to the end of the drain outlet, and a sliding rod is fixedly connected to the middle of the crossbar by bolts.

[0010] Preferably, a sleeve is fixedly connected between the float and the rubber plug, and the sleeve is slidably fitted on the slide rod.

[0011] Preferably, a retaining ring is provided below the float to engage with the inner wall of the external threaded ring, and a connecting line is provided between the retaining ring and the float to limit the distance the float can float.

[0012] Preferably, a sealing ring is fixed to the bottom of the panel.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By opening a hole at the bottom of the test chamber and installing a sinking section on it, and setting a water collection sleeve below the sinking section, the test chamber can be drained when there is a lot of water inside by using a combination of float and rubber plug. When the water is almost drained, the remaining water can be collected into the water collection sleeve, thereby further reducing the impact on the external environment. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0023] Example 1:

[0024] A test chamber drainage device, as described in the following text. Figure 1 - Figure 6A panel 1 is installed on the bottom plate of the test chamber. A recessed section 12 is set inside the panel 1, and a water collection sleeve 2 is set below the recessed section 12. After the bottom of the water collection sleeve 2 is sealed by a rubber stopper 4, a water-containing cavity is formed inside. A float 3 is coaxially set above the rubber stopper 4. The float 3 rises under the action of external water accumulation, causing it to move upwards and opening the drainage channel of the water-containing cavity. When water accumulates inside the test chamber, a small amount of water initially enters the water collection sleeve 2 for storage. As the water volume increases until it reaches the position of the float 3, when the buoyancy generated exceeds the resistance below, the rubber stopper 4 opens, and the water is discharged to the outside through the drain outlet 23. When the subsequent water volume decreases and the buoyancy generated is insufficient to support the weight of the float 3 and the rubber stopper 4, the channel closes again.

[0025] The water collection sleeve 2 includes an internally threaded ring 21 at its top, which is threadedly connected to an externally threaded ring 13 at the bottom of the recessed section 12 to secure it to the panel 1. The water collection sleeve 2 also includes an annular section 22 in the middle and a drain outlet 23 at its bottom. A recessed section 24 connects the annular ring and the drain outlet 23, and the recessed section 24 is used for contact sealing with the rubber plug 4. The contact surface between the recessed section 24 and the rubber plug 4 is inclined.

[0026] A horizontal bar is welded to the end of the drain outlet 23, and a sliding rod 8 is fixedly connected to the middle of the horizontal bar by bolts. A sleeve 5 is fixedly connected between the float 3 and the rubber plug 4, and the sleeve 5 slides on the sliding rod 8. The sliding rod 8 restricts the float 3 from moving upward in the vertical direction, while ensuring that it can return to its initial position when it falls.

[0027] A floating limit structure is provided below the float 3. A retaining ring 6 is provided below the float 3 to engage with the inner wall of the external threaded ring 13, and a connecting line 7 is provided between the retaining ring 6 and the float 3. The connecting line 7 limits the upward distance of the float 3. A sealing ring 11 is fixed to the bottom of the panel 1. The connecting line 7 limits the vertical movement range of the float 3 to 0-2cm.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
