Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Figure 1 This invention illustrates a structural schematic diagram of a waterproof box that meets the IP68 protection rating. Figure 2 A first cross-sectional view of the waterproof box meeting the IP68 protection rating of this invention is shown. Figure 3 It shows Figure 2 Enlarged view of point A in the image. Figure 4 A second cross-sectional view of the waterproof box of this invention, which meets the IP68 protection rating, is shown. Figure 5 It shows Figure 4 Enlarged view of point B in the image. Figure 6A schematic diagram of the structure of the outer door panel in this utility model is shown. Figure 7 A cross-sectional view of the outer door panel of this utility model is shown. Figure 8 It shows Figure 7 Enlarged view of point C in the image. Figure 9A schematic diagram of the structure of the enclosure in this utility model is shown. The waterproof enclosure meeting the IP68 protection level includes: enclosure 1 and an outer door assembly 2 hinged to the enclosure 1; the outer door assembly 2 includes: an outer door panel 21, an observation window 22 and multiple adjustable handles 23. The outer door panel 21 is provided with a mounting hole 211, and the edge of the mounting hole 211 is provided with a first waterproof groove 212. The observation window 22 is installed on the outer door panel 21 and covers the first waterproof groove 212. The multiple adjustable handles 23 are rotatably installed on the outer door panel 21, and the mounting end of each adjustable handle 23 penetrates the outer door panel 21 and extends to form a positioning boss 231. The enclosure 1 is provided with multiple positioning holes 11 that cooperate with the positioning boss 231. The positioning boss 231 is driven by the outer door panel 21 and inserted into the positioning hole 11. In this embodiment, the outer door assembly 2 has eight adjustable handles 23. Two of the eight adjustable handles 23 are located on one side of the outer door panel 21. The eight adjustable handles 23 are evenly distributed on the outer door panel 21. The eight adjustable handles 23 apply force simultaneously from multiple positions, increasing the locking force of the waterproof enclosure and locking the outer door panel 21 onto the enclosure 1, achieving an IP68 protection rating for the waterproof enclosure. Simultaneously, the mounting ends of the eight adjustable handles 23 extend to form eight positioning bosses 231. The observation window 22 covers the first waterproof groove 212. This structure strengthens the sealing space between the observation window and the outer door panel 21, effectively compressing and sealing the gap between them. This significantly reduces the risk of external impurities entering the enclosure 1 through the gap, helping the waterproof enclosure maintain its IP68 protection rating. When the outer door panel 21 is closed on the housing 1, one of the eight positioning protrusions 231 is inserted into one of the eight positioning holes 11, forming a multi-point positioning structure. This allows for simultaneous locking from multiple positions, increasing the locking force of the waterproof housing and ensuring the outer door panel is securely locked to the housing, achieving the IP68 protection rating of the waterproof housing. Furthermore, the inner wall of the positioning hole 11 abuts against the side wall of the positioning protrusion 231, limiting the movement range of the positioning protrusion 231.The eight positioning protrusions 231 are inserted into the eight positioning holes 11, thereby limiting the range of movement of the outer door panel 21 after it is closed with the box body 1, strengthening the connection between the outer door panel 21 and the box body 1, ensuring that the outer door panel 21 remains in contact with the box body 1 after being impacted, and preventing the outer door panel 21 from deforming when it is impacted by external force, which would increase the gap between the outer door panel 21 and the box body 1 and cause leakage channels between the outer door panel 21 and the box body 1, allowing external moisture to penetrate into the box body 1. This reduces the risk of external moisture or pollutants entering the box body 1 through leakage channels, and helps the waterproof box maintain its IP68 protection rating.

[0020] Furthermore, a first waterproof sealing ring 213 is provided within the first waterproof groove 212, with the surface of the first sealing ring abutting against the root of the first waterproof groove 212. When the observation window 22 is installed covering the first waterproof groove 212, the observation window 22 exerts a force on the first waterproof sealing ring 213. The first waterproof sealing ring 213 is deformed by the force of the observation window 22, causing it to fill the first waterproof groove 212 and increasing the contact area between the first waterproof sealing ring 213 and the first waterproof groove 212, as well as between the first waterproof sealing ring 213 and the observation window 22, resulting in a tighter sealing interface. A larger contact area reduces the pressure per unit area, but enhances the overall sealing force, better preventing liquid from passing through the sealing interface, further improving the sealing performance of the waterproof box and ensuring that the waterproof box achieves an IP68 protection rating.

[0021] Furthermore, a second waterproof groove 214 is provided on the outer door panel 21. The second waterproof groove 214 is distributed around the perimeter of the observation window 22, and a EPDM foam sealing strip 215 is provided within the second waterproof groove 214. The foam structure of the EPDM foam sealing strip 215 allows it to fit tightly against the second waterproof groove 214 and fill the entire second waterproof groove 214. The EPDM foam sealing strip 215 has good elasticity and resistance to compression deformation, and can quickly return to its original shape after being compressed, ensuring a long-term sealing effect. When the outer door panel 21 is closed with the box body 1, the edge of the box body 1 is engaged in the second waterproof groove 214, so that the edge of the box body 1 exerts a force on the EPDM foam sealing strip 215. The EPDM foam sealing strip 215 deforms under the force and fits against the edge of the box body 1, increasing the contact area between the box body 1 and the EPDM foam sealing strip 215, thereby increasing the sealing area and improving the sealing effect between the outer door panel 21 and the box body 1. This reduces the risk of external moisture or pollutants entering the interior of the box body 1 through the gap between the outer door panel 21 and the box body 1, ensuring that the waterproof box achieves an IP68 protection level.

[0022] Furthermore, the straight-line distance between any two adjacent adjustable handles 23 is equal. When the adjustable handles 23 lock the outer door panel 21 onto the housing 1, the eight adjustable handles 23 apply force to the outer door panel 21 from eight different directions. Since the distance between any two adjacent handles among the eight adjustable handles 23 is equal, the force exerted by the eight adjustable handles 23 on the outer door panel 21 is more uniform. This means the pressure on the outer door panel 21 is symmetrically distributed in the plane, avoiding localized stress concentration that could cause door panel distortion or sealing strip misalignment. This facilitates the clamping of the EPDM foam sealing strip 215 between the outer door panel 21 and the housing 1, increasing the sealing effect between them and reducing the risk of external moisture or contaminants entering the housing 1 through the gap between the outer door panel 21 and the housing 1, thus ensuring the waterproof housing achieves an IP68 protection rating.

[0023] Furthermore, the housing 1 has a mounting cavity 10, within which an inner door assembly 4 is disposed. The inner door assembly 4 is hinged to one side wall of the housing 1. In this embodiment, various electronic components are disposed within the mounting cavity 10. The inner door assembly 4 is installed at the opening of the mounting cavity 10, and the inner door assembly 4 and the mounting cavity 10 cooperate to temporarily seal the various electronic components within the mounting cavity 10. When the outer door assembly 2 is closed, it forms a first protective layer with the housing 1. When the inner door assembly 4 is closed, it cooperates with the mounting cavity 10 to form an independent sealed space, creating a second protective layer. Thus, two waterproof layers are formed. These two waterproof layers significantly reduce the risk of moisture entering the mounting cavity 10, which helps maintain the IP68 protection rating of the waterproof housing.

[0024] Furthermore, the back of the housing 1 is provided with multiple mounting brackets 3, each of which has a fixing hole 31. In this embodiment, four mounting brackets 3 are provided on the back of the housing 1, and the four mounting brackets 3 are divided into two groups. One group is installed on one long side of the back of the housing 1, and the other group is installed on the other long side of the back of the housing 1. That is, the four mounting brackets 3 on the back of the housing 1 are symmetrically distributed based on the center line of the housing 1, which can make the force on the housing 1 more even during installation, effectively avoid deformation or damage to the housing 1 due to excessive local force, and at the same time enhance the stability of the installation, improve the safety and reliability of the housing 1 during long-term use, and extend the service life of the housing 1. The fixing hole 31 is used to help the mounting bracket 3 fix the entire housing 1 in the corresponding position using the locking assembly, so as to prevent it from being washed away by the water flow when operating in water, which is conducive to fixing the entire waterproof housing in the designated working position.

[0025] Furthermore, the top of the housing 1 is provided with a plurality of connection holes 12, each of which is fitted with an aviation plug 13. The aviation plug 13 is mounted in the connection hole 12 based on the first mounting flange 14. In this embodiment, the top of the housing 1 is provided with three connection holes 12, and each of the three connection holes 12 is fitted with an aviation plug 13, that is, the top of the housing 1 is provided with three aviation plugs 13. A second waterproof sealing ring 141 is provided on the first mounting flange 14. The second waterproof sealing ring 141 is located between the connecting hole 12 and the first mounting flange 14. When the first mounting flange 14 is installed in the connecting hole 12, the first mounting flange 14 exerts a force on the second waterproof sealing ring 141, causing the second waterproof sealing ring 141 to be deformed by the force, increasing the contact area between the second waterproof sealing ring 141 and the first mounting flange 14 and between the second waterproof sealing ring 141 and the inner wall of the connecting hole 12, forming a sealing layer. This reduces the risk of moisture entering the inside of the housing 1 through the gap between the connecting hole 12 and the first mounting flange 14, which is beneficial to protecting the electronic components inside the housing 1 and extending the service life of the electronic components inside the housing 1.

[0026] Furthermore, a waterproof antenna 15 is also provided on the top of the enclosure 1. The waterproof antenna 15 is a mushroom-shaped antenna with a built-in second mounting flange 16 and a third waterproof sealing ring 161. In this embodiment, the third waterproof sealing ring 161 is located between the second mounting flange 16 and the top of the enclosure 1. When the second mounting flange 16 is installed on the top of the enclosure 1, the third waterproof sealing ring 161 is deformed by the pressure of the second mounting flange 16, which increases the contact area between the third waterproof sealing ring 161, the second mounting flange 16, and the top of the enclosure 1, thereby increasing the sealing area and forming a sealing layer. This reduces the risk of moisture entering the interior of the enclosure 1 through the gap between the second mounting flange 16 and the top of the enclosure 1, which helps protect the electronic components inside the enclosure 1 and extends the service life of the electronic components inside the enclosure 1.

[0027] It should be noted that the mushroom-shaped antenna is a core component of GNSS (Global Navigation Satellite System) positioning technology, improving satellite signal reception capabilities through optimized antenna structure. Traditional antennas are prone to positioning errors in scenarios involving multipath effects (interference caused by satellite signals being reflected from the ground) and signal obstruction. However, the mushroom-shaped antenna, with its unique design, can significantly reduce such interference, achieving centimeter-level positioning accuracy.

[0028] Furthermore, the observation window 22 is made of acrylic. Acrylic is highly transparent, allowing staff to clearly view the internal structure of the enclosure 1 from the outside through the acrylic observation window 22. This avoids the need to remove the entire enclosure 1 from the water and open the outer door panel 21 to observe its internal structure when underwater. It also allows staff to directly visually inspect the internal operation of the enclosure 1 through the observation window 22, reducing the frequency of electronic component interruptions.

[0029] Furthermore, the enclosure 1 is made of stainless steel. Stainless steel has high strength and hardness, enabling it to withstand external forces without deformation or damage. This ensures that the enclosure 1 maintains its shape even under high water pressure underwater, preventing deformation that could cause slight deformation of the sealing layer between the enclosure 1 and the outer door assembly 2, creating gaps that would allow moisture to seep into the enclosure 1. This also helps strengthen the structural strength of the enclosure 1. A dense chromium oxide passivation film forms on the surface of the stainless steel, effectively blocking the intrusion of corrosive ions, thus maintaining the stability of the stainless steel enclosure 1 in fresh water or low-salinity water.

[0030] In summary, this invention, by setting multiple positioning bosses and multiple positioning holes, with each positioning boss inserted into one of the multiple positioning holes, forms a multi-point positioning structure. This allows for simultaneous locking from multiple positions, increasing the locking force of the waterproof enclosure and ensuring the outer door panel is locked to the enclosure body, thus achieving an IP68 protection level. Furthermore, by setting multiple adjustable handles evenly distributed on the outer door panel, this invention applies force simultaneously from multiple positions, further increasing the locking force of the waterproof enclosure and ensuring the outer door panel is locked to the enclosure body, achieving an IP68 protection level. Finally, by covering the first waterproof groove with an observation window, this invention strengthens the sealing space between the observation window and the outer door panel, effectively compressing and sealing the gap between them. This significantly reduces the risk of external impurities entering the enclosure through the gap, helping the waterproof enclosure maintain its IP68 protection level.
