Description

Technical Field

[0001] This utility model relates to the field of instrument housing technology, specifically a waterproof, non-invasive instrument housing. Background Technology

[0002] In the field of industrial automation, non-invasive monitoring instruments are widely used in flow monitoring, pressure measurement, and temperature detection due to their simple installation and non-interference with the fluid flow within pipelines. These instruments typically do not require drilling or damaging the pipeline structure, greatly reducing installation difficulty and maintenance costs. However, existing non-invasive instruments still suffer from poor adaptability, cumbersome installation, and insufficient sealing performance when dealing with various pipe diameters and complex operating conditions. These issues limit their further popularization and application.

[0003] Publication No. CN214456135U discloses a remote transmission device for monitoring oil supply pipeline flow. During installation, an inner pipe is inserted into a connecting pipe using locking blocks, ensuring the blocks align with their corresponding slots. The upper pipe is then secured with pipe wrenches. Rotating the upper pipe counter-clockwise causes the blocks to gradually engage with the sloped groove, which in turn gradually narrows counter-clockwise. This process eliminates the need for nut fixing and features a circular array of blocks and grooves for even force distribution and better fixation. This facilitates quick disassembly and replacement of the transmitter, improving oil supply efficiency within the pipeline. While the connecting valve is relatively heavy and difficult to lift manually, the threaded connection between the lifting ring and the valve allows for easy installation. After installation, the lifting ring can be removed counter-clockwise. However, this patent has the following drawbacks in practical use:

[0004] Although this remote flow monitoring device for oil supply pipelines can monitor flow, it requires cutting the pipeline and connecting it through pipeline flanges during installation. Therefore, it cannot be adapted to pipelines of different sizes. In addition, this type of monitoring device can interfere with the flow of fluid, resulting in inaccurate monitoring.

[0005] Therefore, a waterproof, non-invasive instrument housing is proposed to solve the problems mentioned above. Utility Model Content

[0011] Among them, first rotating supports are symmetrically installed on both sides of the bottom of the first magnetic block, and the bottom of the two first rotating supports are rotatably connected to the first rotating magnetic block.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This waterproof non-invasive instrument housing utilizes the magnetic force of the first magnetic block at the bottom of the limiting spring to initially limit the metal tube.

The clamping motor is started to drive the clamping bidirectional threaded rod to rotate, so that the clamping threaded sleeve drives the clamping limiting plate and the lifting sliding bracket to move relative to each other. The lifting sliding sleeve and lifting spring on the outside of the lifting sliding rod can realize the lifting and moving of the second clamping bracket.

[0021] 2. By setting up a waterproof protection mechanism, not only can the monitoring instrument be initially protected using the protective housing and waterproof cover, but by starting the ejector motor to drive the ejector threaded rod to rotate, the ejector threaded rod rotates inside the ejector threaded bracket. The ejector sliding frame drives the ejector sliding rod and ejector plate to move up and down, which can eject the monitoring instrument from inside the protective housing. By pressing down on the opening and closing bracket, under the action of the opening and closing rotating rod, the opening and closing sliding sleeve squeezes the opening and closing spring, which drives the opening and closing protective cover to move relative to each other, which can open the opening and closing protective cover, making it easy to pick up and install the monitoring instrument.

[0032] Working principle: Before using this type of waterproof, non-invasive instrument housing, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 6As shown, firstly, the magnetic force of the first magnetic block 103 at the bottom of the limiting spring 102 allows the first magnetic block 103 to initially limit the metal tube. Simultaneously, the magnetic force of the first rotating magnetic block 105 and the second rotating magnetic block 108 at the bottom further attracts and fixes the metal tube, facilitating the limiting of the instrument housing. The clamping motor 110 is then activated, driving the clamping bidirectional threaded rod 111 to rotate, causing the clamping threaded sleeve 112 to move relative to the clamping limiting plate 113 and the lifting sliding bracket 114. The lifting sliding sleeve 116 on the outside of the lifting sliding rod 115 and the lifting spring 117 enable the lifting and lowering movement of the second clamping bracket 118. Finally, the support spring 119 and the rubber support block 120 achieve the clamping of the pipe. The system is fixed to accommodate pipes of different sizes. Secondly, the protective housing 201 and waterproof cover 202 provide initial protection for the monitoring instrument. By starting the ejector motor 207, the ejector threaded rod 208 is rotated, causing the ejector threaded rod 208 to rotate inside the ejector threaded bracket 204. The ejector sliding frame 206 drives the ejector sliding rod 205 and ejector plate 209 to move up and down, which can eject the monitoring instrument from inside the protective housing 201. By pressing down on the opening and closing bracket 214, under the action of the opening and closing rotating rod 210, the opening and closing sliding sleeve 211 squeezes the opening and closing spring 213 and drives the opening and closing protective cover 216 to move relative to each other, which can open the opening and closing protective cover 216, making it easy to pick up and install the monitoring instrument.
