Retracted sealing waterproof shell device easy for maintenance

Abstract

The invention discloses a retracted sealing waterproof shell device easy for maintenance. The device comprises an upper shell, an annular sealing ring and a lower shell. The annular sealing ring sleeves the upper shell and the lower shell in advance so as to directly assemble and complete a sealing storehouse. The upper shell and the lower shell adopt a four-bayonet spiral structure. The annular sealing ring has a certain deformation and the deformation is a 1-1.5mm thickness change. Because of the deformation of the annular sealing ring, the upper shell and the lower shell are completely waterproof. The waterproof function is achieved through realizing a double-sealing structure by the double-sealing groove design of a sealing ring and an upper shell sealing ring contact plane, and usinga spiral pressing structure to compress the sealing ring in the combination process of the upper shell and the lower shell. The appearance is beautiful, the size of a waterproof shell is small, the device is easy to expand so that a user can conveniently install the device, through one hanging wall screw, the device can be fixed, the device is waterproof with a unique waterproof design and withoutother devices, and the device is convenient to maintain and is safe and reliable.

Description

technical field [0001] The invention relates to an easy-to-maintain retracted and sealed waterproof casing device, which belongs to the technical field of machinery. Background technique [0002] Big data cloud computing is more and more well-known to the society. With the development of urban development environment detection and urban neural network become the development trend of urban intelligence, along with the development of Internet of Things technology, more and more manholes, underground pipe networks, and Urban sewage outlets, remote, water conservancy, and electric power monitoring terminals provide raw data reporting servers and provide necessary big data analysis for city or project managers. The specific conditions of the above application sites may be more complicated, but to provide reliable power supply and stable operation of the circuit, it is required that the power supply or battery is easy to replace and maintain, and the control circuit board needs to...

Problems solved by technology

[0003] Existing IoT devices, especially immersion waterproof structures, are almost always potted with epoxy resin at one time in China. Although the waterproof effect is good, secondary maintenance cannot be performed, which virtually increases the operating cost. For example, an eastern There are tens of thousands of inspection wells in medium-sized cities. If each inspection well needs to be tested, and all of them are disposable devices, it is impossible to replace batteries or maintain circuits. This will increase the waste of resources and cause a huge negative impact on the environment.

[0004] The current relatively high waterproof level adopts direct epoxy or resin potting structure, but once the terminal needs maintenance, it cannot be used again, which is extremely unfavorable to the environment.
