Description
Technical Field
[0001] This application relates to the field of protective boxes, and more particularly to a protective box for power components at the bottom of water. Background Art
[0002] With the rapid development of technology, the laying of underwater cables has become increasingly common, and the connection points between cables need special protection due to the complex underwater environment. Usually, these connection points are placed in specially designed cable boxes to prevent the external environment from affecting them. However, traditional cable box designs face a key problem, that is, how to ensure long-term and stable sealing performance. Traditional sealing methods, such as using sealant or welding, although can provide good sealing effects in the short term, will bring significant difficulties when it is necessary to overhaul or replace internal components. At the same time, in the long-term underwater environment, the effectiveness of these sealing materials may also degrade.
[0003] Some cable box designs currently on the market attempt to improve the sealing performance by adding components such as sealing washers. However, although these improvement schemes have improved the sealing performance to a certain extent, there are still many problems in the actual operation process, such as the operational complexity of the locking mechanism, the reduction of the sealing effect caused by material aging, etc.
[0004] Therefore, how to innovatively design a cable box that can not only maintain excellent sealing performance for a long time but also facilitate the maintenance and replacement of internal components has become an urgent problem to be solved in this technical field. This not only helps to improve the stability and safety of the underwater cable system but also can significantly reduce the maintenance cost and difficulty. Summary of the Utility Model

[0006] The protective box for power components at the bottom of water provided by this application adopts the following technical solutions:
[0007] A protective box for power components at the bottom of water, comprising a box body, a cover body, and a locking assembly. An installation groove is provided on the end face where the box body and the cover body abut. A sealing airbag is arranged in the installation groove. A sealing docking surface is provided on the cover body. When the cover body is closed on the box body, the sealing airbag abuts against the sealing docking surface. A micro air pump is arranged in the box body, and the micro air pump is used to inject gas into the sealing airbag. The locking assembly is arranged on the box body and the cover body, and the locking assembly is used to lock the box body and the cover body.
[0008] By adopting the above technical solution, a novel protection box for power components used underwater is provided. This design combines a box body, a cover body, a locking component, and an innovative sealed airbag mechanism. When the cover body is closed on the box body, the sealed airbag abuts against the sealed docking surface, and gas is injected into the sealed airbag through a micro air pump, enhancing the sealing effect. This design not only helps to maintain long-term sealing performance but also facilitates opening the box body for maintenance or replacement of internal components when needed.
[0009] Preferably, positioning protrusions are provided in the installation groove, and the positioning protrusions are used to fix the sealed airbag.
[0010] By adopting the above technical solution, setting positioning protrusions in the installation groove helps to stably fix the sealed airbag, reducing the probability of the sealed airbag moving or being misaligned during the inflation process, thereby ensuring effective contact between the sealed airbag and the sealed docking surface and further enhancing the sealing performance.
[0011] Preferably, a concave cavity that is inserted and matched with the positioning protrusion is provided on the sealed docking surface. When the cover body is closed on the box body, the positioning protrusion is located in the concave cavity.

[0013] Preferably, an isolation area is provided inside the box body, and the micro air pump is arranged in the isolation area.
[0014] By adopting the above technical solution, the isolation area isolates the micro air pump and the power components installed in the power component protection box, reducing the probability of interference between the micro air pump and the power components during operation.
[0015] Preferably, a one-way valve is provided at the connection between the micro air pump and the sealed airbag.
[0016] By adopting the above technical solution, the one-way valve limits the flow direction of the gas in the sealed airbag, reducing the probability of the gas in the sealed airbag flowing back into the micro air pump, and playing a positive guiding role in maintaining the sealing performance of the sealed airbag.
[0017] Preferably, auxiliary sealing strips are provided on the end surface of the box body that abuts against the sealed docking surface.
[0018] By adopting the above technical solution, an auxiliary sealing strip provides an additional seal for the cover to be closed on the box body, further reducing the gap between the box body and the cover, and playing a positive guiding role in further improving the sealing performance of the power component protection box.
[0019] Preferably, the locking assembly includes a locking tongue and a locking groove. The locking tongue is arranged on the cover body, and the locking groove is arranged on the box body. The locking tongue is in snap-fit with the locking groove.
[0020] By adopting the above technical solution, the locking tongue is snapped into the locking groove by rotating or pressing the box body, realizing quick locking, which facilitates the quick locking and unlocking operations of the power component protection box and improves work efficiency.

[0024] 1. When the cover is closed on the box body, the sealing airbag abuts against the sealing docking surface. By injecting gas into the sealing airbag through the micro air pump, it helps to maintain long-term sealing performance and facilitates opening the box for inspection or replacement of internal components when needed;
[0025] 2. Positioning protrusions are arranged in the installation groove, which helps to stably fix the sealing airbag and reduce the probability of the sealing airbag moving or being misaligned during the inflation process;
[0026] 3. Since a wireless communication module is arranged inside the box body, the operator can remotely adjust the air pressure or detect the sealing state when needed, improving the flexibility and efficiency of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings.
[0033] An embodiment of the present application discloses a power component protection box 1 for underwater use. Referring to Figure 1 and Figure 2 , a power component protection box 1 for underwater use includes a box body 2, a cover body 3, and a locking assembly 4. An installation groove 5 is provided on the end surface where the box body 2 and the cover body 3 are in contact. The installation groove 5 is annularly provided, and a sealing airbag 6 is arranged in the installation groove 5. A sealing docking surface is provided on the cover body 3. When the cover body 3 is closed on the box body 2, the sealing airbag 6 abuts against the sealing docking surface. A micro air pump 7 is arranged in the box body 2, and the micro air pump 7 is used to inject gas into the sealing airbag 6. The locking assembly 4 is arranged on the box body 2 and the cover body 3, and the locking assembly 4 is used to lock the box body 2 and the cover body 3.
[0034] Specifically, a through hole 14 is provided on the box body 2, and the through hole 14 is used for the wire to penetrate. After the wire penetrates, the through hole 14 needs to be sealed to reduce the probability of liquid entering the box body 2 along the through hole 14.
[0035] At the same time, referring to Figure 2 and Figure 3 , an isolation area 10 is arranged in the box body 2, and the micro air pump 7 is arranged in the isolation area 10. The box body 2 is separated by the isolation area 10 to reduce the probability of mutual interference between the micro air pump 7 and the power components installed in the box body 2 during operation.
[0036] Correspondingly, the power cord of the micro air pump 7 is connected to the power component, and the micro air pump 7 is powered by a wire. At the same time, a backup power supply 15 is arranged in the isolation area 10. When the power component powers the micro air pump 7, the backup power supply 15 can also be charged, reducing the probability that due to a sudden power failure of the power component, the micro air pump 7 cannot inflate the sealing airbag 6, resulting in an increase in the clearance between the cover body 3 and the box body 2 and liquid entering the box body 2 along the clearance.
[0037] On the other hand, a one-way valve 11 is provided at the connection between the micro air pump 7 and the sealed airbag 6. The one-way valve 11 is installed in the isolation area 10. By the one-way valve 11, the flow direction of the gas in the sealed airbag 6 is defined, reducing the probability of the gas in the sealed airbag 6 flowing back into the micro air pump 7, and playing a positive guiding role in maintaining the sealing performance of the sealed airbag 6.
[0038] In addition, a wireless communication module 13 is provided in the box body 2. The wireless communication module 13 is electrically connected to the micro air pump 7. An operator can connect to the wireless communication module 13 through a dedicated application program. Through the wireless communication module 13, the working state of the micro air pump 7 can be observed in real time, enabling the operator to remotely adjust the air pressure or monitor the sealing state when needed, facilitating the timely discovery of abnormal situations and their disposal, and improving the flexibility and efficiency of maintenance.
[0039] Refer to Figure 2 and Figure 4 , a positioning protrusion 8 is provided in the installation groove 5. The positioning protrusion 8 is used to fix the sealed airbag 6.
[0040] Specifically, there are six groups of positioning protrusions 8. The six groups of positioning protrusions 8 are evenly distributed along the circumferential direction of the installation groove 5 on the installation groove 5. Since the forming methods of the six groups of positioning protrusions 8 are the same, any one group of positioning protrusions 8 is taken for description. The positioning protrusion 8 is located on both sides of the installation groove 5 in the width direction. When the sealed airbag 6 is located in the installation groove 5, the positioning protrusion 8 can just be located on both sides of the sealed airbag 6.
[0041] Therefore, providing the positioning protrusion 8 in the installation groove 5 helps to stably fix the sealed airbag 6, reducing the probability of the sealed airbag 6 moving or being misaligned during the inflation process, thereby ensuring the effective contact between the sealed airbag 6 and the sealed docking surface and further improving the sealing performance.
[0042] Correspondingly, a concave cavity 9 that is inserted and matched with the positioning protrusion 8 is provided on the sealed docking surface. The number of the concave cavities 9 corresponds to the number of the positioning protrusions 8 one by one. By providing the concave cavity 9 that is inserted and matched with the positioning protrusion 8 on the sealed docking surface, when the box body 2 is closed, the positioning protrusion 8 can accurately enter the concave cavity 9, realizing the precise positioning and alignment of the box body 2 and the cover body 3, which helps to improve the overall sealing effect. At the same time, through the guiding cooperation of the protrusion and the groove, the steps of covering the cover body 3 are simplified.
[0043] On the other hand, an auxiliary sealing strip 12 is provided on the end surface of the box body 2 that abuts against the sealing docking surface. The auxiliary sealing strip 12 is annularly installed on the box body 2. Specifically, the auxiliary sealing strip 12 is made of silica gel material, so that the auxiliary sealing strip 12 has the characteristics of corrosion resistance and easy deformation. By means of the auxiliary sealing strip 12, an additional seal is provided for the cover body 3 to cover the box body 2, further reducing the gap between the box body 2 and the cover body 3, and playing a positive guiding role in further improving the sealing performance of the power component protection box 1.
[0044] Referring to Figure 1 , Figure 2 and Figure 4 , the locking assembly 4 includes a locking tongue 41 and a locking groove 42. The locking tongue 41 is provided on the cover body 3, and the locking groove 42 is provided on the box body 2. The locking tongue 41 is in snap-fit with the locking groove 42.
[0045] Specifically, six groups of locking assemblies 4 are provided. The six groups of locking assemblies 4 are circumferentially arranged along the outside of the power component protection box 1. Through the cooperation of the six groups of locking assemblies 4, the probability of the cover body 3 falling off the box body 2 due to the failure of any one or more groups of locking assemblies 4 is reduced.
[0046] Thus, by rotating or pressing the box body 2 to make the locking tongue 41 snap into the locking groove 42, quick locking is achieved, which facilitates the quick locking and unlocking operations of the power component protection box 1 and improves work efficiency.
[0047] Therefore, the implementation principle of an embodiment of a power component protection box 1 for underwater of the present application is as follows: Through the combination of the innovative sealing airbag 6 and the micro air pump 7, long-term stable sealing performance is achieved, and the maintenance and replacement process is simplified. The designs of the positioning protrusion 8, the groove, the isolation area 10, the one-way valve 11, the auxiliary sealing strip 12, etc. further enhance the sealing effect and durability. The optimization of the locking assembly 4 improves the operation convenience, and the addition of the wireless communication module 13 improves the intelligent level and maintenance efficiency of the system. The overall design takes into account the sealing performance, maintainability and intelligent requirements.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
