Description

Technical Field

[0001] The present invention relates to the technical field of battery protection, and in particular to a waterproof device capable of quickly replacing a power supply module and a replacement method thereof. Background Art

[0002] At present, a large number of IoT smart terminal devices are used in application scenarios in industries such as water and gas to monitor the overall working status of the platform. When the power supply of the equipment reaches the designed service life or the power supply itself fails, it needs to be replaced. Since the equipment is usually installed in underground environments such as pipe wells, it will be affected by water immersion and dust, causing internal circuit failure. Therefore, the terminals of this type of equipment are usually designed to be waterproof and dustproof. When maintenance personnel open the equipment to replace the battery, the initial state of the waterproof and dustproof structure inside the original equipment is often destroyed. After completing the battery replacement work, it is difficult to achieve good secondary sealing of the equipment by artificial means. However, poor sealing inside the equipment can easily cause the circuit system of the equipment to fail to work properly, causing damage such as overheating, short circuit, and burning of the lines and devices. Therefore, it is necessary to achieve good sealing performance while achieving rapid replacement of the power supply of the equipment.

[0003] There are generally three ways to replace the power supply during traditional after-sales maintenance: one is to directly replace the power supply part after opening the equipment. When reinstalling the equipment, the outer shell and the cover are simply sealed with a sealing ring: this method has the problems of easy deformation of the sealing ring, uneven pressing force of the shell cover resulting in gaps on the joint surface, and easy aging of the sealing ring after long-term use, and poor sealing protection effect, making it difficult to achieve a good protection level; the second is to use an external power supply cable to connect the on-site glue filling method, but this method requires more lead maintenance length to be reserved, and the exposed cables will increase the difficulty of construction when laying out the equipment on the project site, and the integrity of the equipment is poor; the third is to use pre- The method of replacing the entire equipment with potting glue is to directly replace the entire equipment when replacing the battery on site. This method has good waterproof protection effect, but from the perspective of cost and maintainability, this solution increases the manufacturing cost due to the overall replacement. The returned after-sales equipment is usually sealed inside the equipment as a whole by potting glue when the power supply leaves the factory. The hardness of the potting resin after curing is very high, and it is difficult to remove the original battery pack without damage. Even after removal, the residual glue remaining around the battery pack and at the terminals is difficult to remove, which further leads to the deterioration of the recyclability of the product. In addition, this method does not support the replacement of local components of the equipment or opening the cover for maintenance, and the maintainability is poor. Summary of the invention

The waterproof terminal housing 1 is sealed and connected with the pressing screw cap 5 through the sealing thread;

[0049] The rapid prototyping filling sealant 3 a is used to fill the replacement sealing chamber 3 .

[0051] It should be noted that the upper cover body 4 and the replaceable power supply module 2 are both prefabricated modules filled with sealant. The replaceable sealing chamber 3 can be quickly filled with sealant to form a sealing chamber module. The combination of these three parts can provide a sealing protection effect. The function of the waterproof terminal shell 1 is to protect the internal module and mainly assemble internal structural parts. The battery of the device itself does not need to rely on the sealing ring on the outer shell and other protective measures to achieve battery sealing protection. The rapid molding sealant 3a is solid after curing.

[0057] Furthermore, the replacement sealing chamber 3 further comprises: a glue inlet 31, a top glue sealing gasket step 34, a sealing chamber internal space 35 and a bottom glue sealing gasket step 36;

[0058] The glue inlet 31 is located on the side of the replacement sealing chamber 3; the top sealing gasket step 34 surrounds the sealing chamber internal space 35; the sealing chamber internal space 35 is located in the depression in the middle of the top of the replacement sealing chamber 3; the bottom sealing gasket step 36 is located above the baffle 23.

In daily use, the replacement sealing chamber 3 is filled with sealant. During maintenance, a new replacement sealing chamber will be replaced for replacement, and the internal space of the new replacement sealing chamber is not filled with sealant at the beginning; after installing other components, the sealed bottom glue sealing gasket 7 and the top glue sealing gasket 8 are placed at the corresponding positions of the top glue sealing gasket step 34 and the bottom glue sealing gasket step 36 respectively, so that a closed space is formed in the new replacement sealing chamber; the filled sealant will slightly overflow through the exhaust hole 33, and the excess sealant can be conveniently collected in the overflow glue groove 32.

[0060] Furthermore, the upper cover body 4 also includes: a circuit board body 41, a positioning bayonet 42 and a pressing end surface 44;

[0061] The circuit board body 41 is located in the middle of the sealing area inside the upper cover body 4; the positioning bayonet 42 is located on the side of the bottom of the upper cover body 4; the clamping end surface 44 is located in the middle of the bottom of the upper cover body 4, and the mainboard terminal socket 43 is embedded in the clamping end surface 44.

In addition, the tight fit design can ensure that the terminal contact surface is closer, ensure effective current transmission, and the contact end surface area of ​​the terminal will not penetrate the sealant filled later, ensuring good electrical performance.

[0063] Specifically, the rapid prototyping filling sealant 3 a is filled from bottom to top by entering from the glue inlet valve 6 and gradually rising to the glue overflow groove 32 .

[0064] In the specific implementation, the rapid prototyping filling sealant 3a is filled from bottom to top. The sealant enters from the bottom of the container, and the liquid level gradually rises to the top overflow groove, which can ensure that the internal electrical components are completely wrapped, filled and protected during the rising process of the liquid level; there is no need to disassemble the equipment to complete the sealing, and the filling from bottom to top can completely fill the components in the warehouse, and the sealing molding protection time is short.

[0065] The waterproof device that can quickly replace the power supply module has excellent dust and water protection capabilities. There are no exposed cables on the outside of the waterproof device, and the equipment has good integrity.
