[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0029] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] Embodiment 1:

[0031] Reference Figure 1-4As shown, a pipe network situation awareness terminal based on multiple waterproof technologies includes an upper shell 1, on which three waterproof connectors 3 are arranged (the waterproof connectors 3 all adopt existing mature technologies and have reliable waterproof performance), the upper shell 1 and the lower shell 2 are assembled to form a closed chamber, a partition 12 is arranged in the closed chamber, the partition 12 separates the closed chamber into a first chamber 13 and a second chamber 14, the first chamber 13 and the second chamber 14 are not completely closed, and the two are connected, the three waterproof connectors 3 are all arranged on the side of the first chamber 13, the second chamber 14 is provided with a circuit board module 4, and the circuit board module 4 contains the prior art Signal receiving / transmitting electronic components and control chips, etc., the circuit board module 4 is connected to the external sensor (such as temperature sensor, pressure sensor, flow rate sensor, etc., which are set according to actual conditions) through the waterproof connector 3 to receive relevant status information in the pipe network; an openable sealing cover 5 is provided on the circuit board module 4, and the opening of the sealing cover 5 is used to install the Internet of Things card; the first chamber 13 is filled with potting glue to cover the inner sides of the three waterproof connectors 3, the circuit board module 4 is fixed to one side of the upper shell 1, and its surface is also covered with potting glue, leaving only the top of the sealing cover 5, so as to facilitate opening the sealing cover 5 to disassemble and assemble the Internet of Things card.

[0032] After long-term use, the bonding performance of the potting glue will decrease, and a gap will be generated between the device and the shell. If the waterproof performance of the waterproof joint 3 decreases, there will be a risk of leakage inside the cavity, so the internal closed chamber is divided into a first chamber 13 and a second chamber 14, and the waterproof joints 3 connected to the outside are arranged in the first chamber 13, potted separately, and separated from the circuit board module 4. In case the potting glue of the waterproof joint 3 and the first chamber 13 fails at the same time, the circuit board module 4 is in an independent potting glue state, which can reduce the risk of water ingress into the circuit board module 4 and improve the durability of the utility model.

[0033] The sealing cover 5 includes a cover body 51 and an end cover 52. The cover body 51 is arranged on the circuit board module 4. The cover body 51 is a column with a central penetration. A circle of first bosses 521 is arranged at the bottom of the end cover 52. The side of the first boss 521 is interference fit with the inner side of the cover body 51. The Internet of Things card can be disassembled and assembled by removing the end cover 52, which is simple and convenient. A layer of rubber is attached to the lower end surface of the end cover 52 and the surface of the first boss 521. The provision of a layer of rubber can improve its sealing and prevent moisture from entering. Compared with the traditional addition of a sealing gasket, the production and assembly efficiency is higher.

[0034] A circle of second bosses 15 is provided at the bottom of the upper shell 1, and a groove is provided at the top of the lower shell 2. The groove cooperates with the second boss 15, and a sealing ring 8 is also provided in the groove. The upper shell 1 and the lower shell 2 are assembled by six sets of bolts and nuts. When the upper shell 1 and the lower shell 2 are locked, the sealing ring 8 is squeezed, and its sealing performance is better, and it can be opened for maintenance when necessary.

[0035] The upper shell 1 is also provided with a transparent window 11, and the circuit board module 4 is provided with an indicator light at a position corresponding to the transparent window 11, which is used to display the status of the pipeline network situation awareness terminal.

[0036] The battery box 6 and the battery 7 in the battery box 6, the battery box 6 is arranged on the lower shell body 2, the battery box 6 is filled with potting glue to cover the battery 7, the battery 7 is electrically connected to the circuit board module 4 to provide power for the circuit board module 4, and the battery 7 is fixed separately, which can facilitate the later maintenance and replacement of the battery 7.

[0037] The potting glue used is silicone potting glue, which has strong anti-aging ability, good weather resistance, good impact resistance, excellent resistance to cold and heat changes and electrical properties, good thermal conductivity and flame retardancy.

[0038] Embodiment 2:

[0039] The present embodiment is different from the first embodiment in that the potting glue is made of a variety of materials. The first chamber 13 is potted with polyurethane potting glue, and the second chamber 14 and the battery box 6 are potted with silicone potting glue. This is because polyurethane potting glue usually provides better bonding performance than silicone potting glue. The use of polyurethane potting glue at the position of the waterproof joint 3 will result in better waterproof performance. However, the high temperature resistance of polyurethane potting glue is poor and is not suitable for the second chamber 14 and the battery box 6. Silicone potting glue has good high and low temperature resistance, so it can obtain better waterproof performance.

[0040] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
