Description

Technical Field

[0001] This utility model relates to the field of underwater sealed chamber testing technology, specifically to an airtightness test platform for an underwater sealed chamber. Background Technology

[0002] Underwater sealed chamber airtightness testing is a quality inspection technology for underwater equipment (such as the sealed chambers of submersibles and underwater robots). It uses specific methods to detect whether there is gas leakage, so as to ensure that the chamber can remain dry inside the underwater environment and that the equipment can operate normally. It can detect potential leaks in the sealed chamber in advance, avoid damage to the equipment underwater due to water ingress, and greatly improve the operational reliability and service life of underwater equipment.

[0003] A search revealed that patent CN216081928U discloses a device for detecting the airtightness of a sealed chamber for biopharmaceutical applications. The device includes a base plate, a vacuum pump fixedly mounted on the top of the base plate via bolts, a connector fixedly mounted on the output end of the vacuum pump via a hose, and a water tank fixedly mounted on the top of the base plate via bolts. Two sets of collars are fixedly mounted on the inner wall of the water tank, with the upper collar inserting into the chamber. The beneficial effects of this invention are: by placing the chamber in water, the vacuum pump extracts air from the chamber, increasing the pressure difference between the inside and outside of the chamber. If the chamber leaks air, water will quickly enter, facilitating airtightness detection. It utilizes the principle of anhydrous copper sulfate reacting with water to quickly turn blue; when there is water on the inner wall of the chamber, the anhydrous copper sulfate quickly turns blue, rapidly detecting whether the chamber is leaking air. The detection speed is fast and the efficiency is high.

[0004] The existing devices have some drawbacks in use. For example, the above scheme uses a vacuum pump in conjunction with a water tank to extract air from the chamber by operating the vacuum pump. The air tightness of the chamber is then judged by observing whether water has entered. Although the test results can be judged, the chamber material itself has a certain degree of airtightness, and a single static water tightness test cannot simulate the air tightness of the chamber under impact. Therefore, it is not conducive to improving the comprehensiveness of the chamber air tightness test. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figures 1-4 As shown, this utility model provides a technical solution: an airtightness test platform for an underwater sealed chamber, including a base plate 1 and a testing component 2. The testing component 2 includes a stand 201 installed on the top of the base plate 1, and a top plate 202 is installed on the top of several stands 201. The detection assembly 2 also includes a propulsion chamber 203 mounted on the top of the base plate 1. Several propulsion chambers 203 are arranged in a circular array on the top of the base plate 1. A mounting base 204 is fixedly connected to the inner bottom of each propulsion chamber 203. A drive motor 205 is mounted on the inner wall of the mounting base 204. A drive rod 206 is coaxially driven to the output end of the drive motor 205. A turbine 207 is fixedly sleeved on the outer wall of the drive rod 206. A protective cover 208 is snapped onto the inner wall of the propulsion chamber 203 on one side of the turbine 207. The detection assembly 2 also includes a propulsion chamber mounted on... The bottom end of the top plate 202 has a connecting bend 209. Multiple connecting bends 209 are symmetrically arranged at the center of the bottom plate 1. An mounting sleeve 210 is fixedly connected to the outer wall of each connecting bend 209. A thruster 211 is installed at the inner bottom end of the mounting sleeve 210. Specifically, the bottom plate 1 provides sufficient support for the detection component 2, ensuring its stability during testing. The detection component 2 can perform airtightness testing on the cabin from multiple angles and directions, simulating various underwater operating conditions of the sealed cabin through water flow impact. This improves the comprehensiveness of the test data. Multiple propulsion chambers 203 installed at the top of the base plate 1 can drive the drive rod 206 to rotate using the drive motor 205 that moves the inner wall of the chamber. This causes the turbine 207 sleeved at the end of the drive rod 206 to rotate rapidly, thus simulating various underwater working conditions of the sealed chamber using the impact of water. At the same time, the strength of the chamber wall can be detected simultaneously through the impact of water flow. The mounting base 204 provides sufficient stability for the operation of the drive motor 205, preventing it from shaking or becoming unstable during operation. The connecting bend plate 209 installed at the bottom of the top plate 202 can be quickly connected to the mounting sleeve 210, thereby stabilizing the propeller 211 inside the mounting sleeve. Multiple propellers 211 can then be used to synchronously simulate the impact effect of water flow from the longitudinal direction, further improving the comprehensiveness of the airtightness test data. It should be noted that all the drive equipment mentioned in this article has its own power source, and the data control console 3 is existing technology, so it will not be described in detail in this article.

[0018] As one implementation method in this embodiment, such as Figure 2 and Figure 4As shown, a data control console 3 is installed on the top of the base plate 1, a counterweight 4 is installed on the top of the data control console 3, and a cover plate 5 is snapped onto the top of the counterweight 4. A sealing box 6 is installed on the top of the top plate 202. The outer surface of the sealing box 6 has several slots 7. The outer surface of the top plate 202 has several mounting slots 8. A pointing slot 9 is located inside the mounting slots 8 on the top of the top plate 202. In actual use, the data during the detection process can be recorded and transmitted in real time through the data control console 3 installed on the top of the base plate 1. The counterweight 4 provides sufficient weight to the equipment, thereby improving its operational stability. Multiple encapsulation boxes 6 on the top of the top plate 202 protect the precision equipment from external impacts. The slots 7 on its side walls provide both heat dissipation and facilitate the lifting of the testing platform by external hoisting equipment. Multiple mounting slots 8 on the outer surface of the top plate 202 allow for flexible installation of external equipment. The directional slots 9 allow operators to quickly install the testing platform according to the instructions, further reducing the labor intensity of the operators.

[0019] A traction block 10 is fixedly connected to the lower end of the base plate 1, and a traction rod 11 is fixedly connected to the outer wall of the traction block 10. The outer surfaces of the base plate 1, top plate 202, propulsion chamber 203, and turbine 207 are all coated with a waterproof coating and an anti-rust coating. In actual use, the traction block 10 at the lower end of the base plate 1 can be stably connected to the traction rod 11, and the traction rod 11 can be used to facilitate the transportation of the base plate 1, thereby improving the transportation convenience of the testing platform. The waterproof coating and anti-rust coating on the outer surfaces of the base plate 1, top plate 202, propulsion chamber 203, and turbine 207 can improve the service life of the testing platform.

[0020] Working principle: The testing platform is hoisted by external hoisting equipment. After the platform equipment is installed, it is sealed by an external airtight enclosure. Once filled with liquid, the drive motor 205 is started, causing the drive rod 206 at its output end to drive the turbine 207 to rotate at high speed. This, in conjunction with the two longitudinal thrusters 211, simulates various working conditions of the sealed chamber underwater, thereby testing the airtightness of the sealed chamber under different operating conditions. The data control console 3 records and transmits the test data, and the airtightness of the sealed chamber is determined through data analysis.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
