[0037] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough in its understanding and will fully convey the scope of the present application to those skilled in the art.

[0038] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0039] In factories or temporary construction sites, video surveillance equipment, such as PTZ cameras, mounted on scaffolding, needs to be rotated and adjusted constantly to adapt to changes in the monitored area or the positions of personnel. Because this equipment requires flexible rotation, its sealing cannot be completely airtight. This means that in rainy weather or humid construction environments, moisture from the air can enter the equipment, causing fogging on the internal lenses and affecting image quality. Manual disassembly and maintenance are required before it can be put back into use, and in more serious cases, internal circuitry can be damaged, resulting in economic losses. Simultaneously, the video surveillance equipment loses its monitoring and recording functions.

[0040] This application proposes a confined space networking device based on unsafe behaviors in power plants. A housing is installed on the installation platform. The housing and the installation platform are sealed together. Specifically, the tight fit between the first sealing part and the second sealing part forms a sealed accommodating space between the housing and the installation platform. The monitoring equipment is installed in the accommodating space and is protected against moisture and water.

[0041] Example 1

[0042] Reference Appendix Figure 1-3 Embodiment 1 of this application proposes a limited space networking device based on unsafe behaviors of power plants, which includes: an installation platform 1, a housing 2, a first sealing part 3 and a second sealing part 4.

[0043] The mounting platform 1 is a platform with a certain thickness; the shell 2 is a hemispherical transparent shell, and the end face of the shell 2 is separable from that of the mounting platform 1, and has an open first state and a closed second state relative to the mounting platform 1.

[0044] The first sealing part 3 is disposed on the end face of the mounting platform 1 and is disposed along the edge line of the end face;

[0045] The second sealing part 4 is circumferentially disposed at the edge of the housing 2;

[0046] When the housing 2 is in the second state, the inner wall of the housing 2 and the end face of the mounting platform 1 form an accommodating space, which is used to accommodate the monitoring equipment. At this time, the first sealing part 3 and the second sealing part 4 cooperate to keep the accommodating space in a sealed state that isolates it from the outside.

[0047] Specifically, the mounting platform 1 provides an area for installing the monitoring equipment and also supports it. It can be made of a metal material with a certain strength. The upper surface of the mounting platform 1 is used to install the monitoring equipment, and the lower end can be connected to support legs or feet to increase the height of the mounting platform and provide stability. The shape of the mounting platform 1 can be rectangular, triangular, or circular. This embodiment provides a circular mounting platform 1.

[0048] The outer shape of housing 2 is a hemispherical arc-shaped structure, with a hollow interior. Housing 2 covers the mounting platform 1, and together with the upper surface of the mounting platform 1, they form an accommodating space, providing sufficient space for the installation and flexible rotation of the monitoring equipment. The apex of the arc of the hemispherical housing 2 is concentric with the circular mounting platform 1. Housing 2 can be made of transparent hard plastic or tempered glass. Transparency does not affect the equipment's imaging effect, and the chosen material itself has a certain strength, providing a sealing and moisture-proof function for the accommodating space while also offering some impact protection for the monitoring equipment on the mounting platform 1. Due to the hemispherical design, concentrated forces can be dispersed. Compared to a flat structure, the hemispherical structure resists deformation more effectively under pressure, converting vertically downward forces into tensile and compressive forces distributed along the structural curve. These forces, combined with the curvature of the structure, form a stable support system, utilizing the tensile and compressive strength of the material to improve the stability of housing 2. It can also reduce stress concentration, avoid a sharp increase in stress at certain points, reduce the risk of cracking caused by stress concentration, and in the event of dynamic impact, such as a collision, the hemispherical structure can absorb and dissipate energy through its elastic properties. For example, when a spring deforms, the hemispherical structure bends under force, then releases energy to return to its original shape, dissipating the impact energy and reducing the impact on the overall structure. The hemispherical shell 2 structure itself has the above properties, and by combining it with the material properties of plastic and tempered glass, it can bring even better performance. It is sufficient to withstand the direct impact damage of falling objects or wind-blown debris on the monitoring equipment. If the equipment is tilted under external force, the shell 2 will make contact with the ground in advance, achieving a buffering effect on the impact of the ground, thereby protecting the monitoring equipment on the installation platform 1.

[0049] To facilitate the installation of the monitoring equipment, the housing 2 and the mounting platform 1 are designed to be separable, allowing for flexible disassembly of the housing 2. The connection method can be either a plug-in connection, with a recessed slot on the mounting platform 1 and a protruding insert at a corresponding position on the housing 2, enabling a detachable connection between the slot and the insert. Alternatively, a hinge connection can be used, with a first outward-extending hinge point on the mounting platform 1 and a corresponding outward-extending second hinge point on the housing 2. The housing 2 and the mounting platform 1 are hinged together, allowing for a separable (detachable) design. The housing 2 can rotate relative to the mounting platform 1 around the hinge point, achieving a semi-separated effect. The housing 2 is connected to the mounting platform 1 via the hinge point, achieving a unified design for both housing 2 and mounting platform 1, facilitating use.

[0050] The first sealing part 3 is arranged around or surrounds the mounting platform 1, and the second sealing part 4 is arranged around or surrounds the periphery of the housing 2. The first sealing part 3 and the second sealing part 4 form a sealing state by means of inner and outer nesting and bonding contact, or by means of direct contact bonding contact.

[0051] The first state is when the housing 2 is separated from the mounting platform 1, and the housing 2 is open relative to the mounting platform 1. At this time, the monitoring equipment is installed and removed on the mounting platform 1. The second state is when the housing 2 is assembled with the mounting platform 1, and the housing 2 is closed relative to the mounting platform 1. When it is closed, a sealed accommodating space is formed.

[0052] Further, see attached document. Figure 1-4 In some embodiments, the first sealing portion 3 includes at least one annular plate 5 and a first sealing layer 31;

[0053] The ring plate 5 is a ring-shaped plate with its first end set on the end face of the mounting platform 1 and its second end extending away from the end face. The first sealing layer 31 is wrapped around the outside of the ring plate 5.

[0054] The second sealing part 4 includes a second sealing layer 41, which is disposed on the edge of the housing 2;

[0055] When the housing 2 is in the second state, the second sealing layer 41 is in close contact with the first sealing layer 31.

[0056] Specifically, in order to achieve a sealing effect of the accommodating space when the housing 2 is in the second state, the technical solution adopted in this application is that the first sealing part 3 on the mounting platform 1 is formed by vertically setting at least one ring plate 5 on the upper end surface of the mounting platform 1, and the ring plate 5 is wrapped with a first sealing layer 31.

[0057] The second sealing part 4 on the housing 2 is provided by providing a second sealing layer 41 on the inner and / or outer side of the edge of the housing 2; when the housing 2 is closed relative to the mounting platform 1, the first sealing part 3 and the second sealing part 4 are misaligned and engaged, and the sidewalls of the first sealing layer 31 and the second sealing layer 41 are in close contact.

[0058] One type of misaligned connection involves a housing 2 having an edge diameter smaller than the annular plate 5. The outer wall of the second sealing layer 41 on the outer edge fits against the inner wall of the first sealing layer 31 on the annular plate 5, achieving a seal. The above illustrates one example of a misaligned connection; other forms will not be described further to ensure brevity.

[0059] The ring plate 5 is a circular plate structure with an outer diameter no larger than the inner diameter of the circular mounting platform 1, and its center is concentric with that of the circular mounting platform 1. The edge of the shell 2 refers to the edge furthest from the apex of the hemispherical shell 2. Both the ring plate 5 and the edge of the shell 2 have a certain strength to provide internal support for the sealing layers respectively mounted on them. To achieve a complete seal when the first sealing layer 31 and the second sealing layer 41 are bonded together, both are made of elastic materials, such as silicone or rubber. The shell 2 is closed, and the two layers are pressed together, ensuring that there are no gaps on the contact surfaces of the first sealing layer 31 and the second sealing layer 41.

[0060] Further, see attached document. Figure 4-6 In some embodiments, there are two ring plates 5, namely a first ring plate 51 and a second ring plate 52, and the diameter of the first ring plate 51 is larger than the diameter of the second ring plate 52. The second ring plate 52 is spaced apart from the first ring plate and coaxially arranged.

[0061] An assembly groove 53 is formed between the inner wall of the first ring plate 51 and the outer wall of the second ring plate 52. The second sealing part 4 is embedded in the assembly groove 53, and the second sealing layer 41 is tightly attached to the first sealing layer 31.

[0062] Specifically, in order to enhance the sealing effect, the technical solution adopted in this application uses two ring plates 5 with different diameters in the first sealing part 3. The first ring plate 51 and the second ring plate 52 are coaxially and concentrically set on the mounting platform 1. Since the two have different diameters, an assembly groove 53 is formed between the inner side wall of the first ring plate 51 and the outer side wall of the second ring plate 52.

[0063] When the housing 2 is closed, its edge is inserted into the assembly groove 53, so that the outer walls of the second sealing layer 41 on both sides of the edge of the housing 2 are in close contact with the inner walls of the first sealing layer 31 on the first ring plate 51 and the outer walls of the first sealing layer 31 on the second ring plate 52, respectively. This achieves a sealing effect between the housing 2 and the mounting platform 1. The difference in diameter between the first ring plate 51 and the second ring plate 52 is greater than the wall thickness of the edge of the housing 2.

[0064] The heights of the two ring plates 5 can be the same or different. In one embodiment of the first sealing part 3, the first ring plate 51 is higher than the second ring plate 52, and the first ring plate 51 forms a sealing barrier on the outside of the assembly groove 53. In another embodiment, the first ring plate 51 is lower than the second ring plate 52, and the second ring plate 52 forms a sealing barrier on the inside of the assembly groove 53.

[0065] Further, see attached document. Figure 1-5In some embodiments, a pressing plate 6 is also included. The pressing plate 6 is arranged around the outer periphery of the edge of the housing 2. An annular plate 5 is provided on the end face of the pressing plate 6. The first end of the annular plate 5 is fixedly disposed with the end plate of the pressing plate 6, and the second end extends away from the arc apex of the housing 2. The second sealing layer 41 is wrapped around the outside of the annular plate 5.

[0066] Specifically, in order to achieve a tight fit between the housing 2 and the mounting platform 1 when closed, the technical solution adopted in this application adds a pressing plate 6 to the outer periphery of the edge of the housing 2.

[0067] When the housing 2 is closed, a ring plate 5 is provided on the end face of the pressing plate 6 facing the mounting platform 1. One end of the ring plate 5 is vertically positioned on the end face of the pressing plate 6, and the other end extends towards the mounting platform 1. The structure of the ring plate 5 is the same as described above. The diameter of the ring plate 5 is between the diameters of the first ring plate 51 and the second ring plate 52, so that when the housing 2 is closed, the ring plate 5 on the pressing plate 6 can be inserted into the assembly groove 53. At this time, vertical pressure (perpendicular to the end face of the mounting platform 1) is applied to the pressing plate 6, causing the second sealing layer 41 to be sandwiched between the two first sealing layers 31 and to be in close contact with each other. Applying pressure through the pressing plate 6 not only facilitates operation but also ensures comprehensive and balanced pressure. By pressing the pressing plate 6, the first sealing part 3 and the second sealing part 4 are completely fitted together, further improving the sealing effect.

[0068] Further, see attached document. Figure 5 In some embodiments, the cross-sections of the first sealing layer 31 and the second sealing layer 41 are both mushroom-shaped, including a head 311 and a neck 312, and the cross-sectional area of ​​the head 311 is larger than that of the neck 312, and the junction of the head 311 and the neck 312 is a concave arc surface.

[0069] Specifically, to achieve stable adhesion between the first sealing layer 31 and the second sealing layer 41, the technical solution adopted in this application involves making the cross-sections of both the first sealing layer 31 and the second sealing layer 41 mushroom-shaped. When they are in contact, the head 311 and neck 312 of the first sealing layer 31 and the head 311 and neck 312 of the second sealing layer 41 are in staggered contact. That is, the head 311 of the first sealing layer 31 is close to the neck 312 of the second sealing layer 41, and the neck 312 of the first sealing layer 31 is close to the head 311 of the second sealing layer 41. Since the cross-section of the head 311 is larger than that of the neck 312, a snap-fit ​​structure can be formed through the cooperation between the head 311 and the neck 312, so that the head 311 of the first sealing layer 31 and the neck 312 of the second sealing layer 41 are snapped together, achieving a limiting and fixing effect and improving the stability of the bond. Furthermore, the junction between the head 311 and the neck 312 is a concave arc surface. The concave arc surface can provide contact between the head 311 and facilitate relative sliding, reducing friction. Through a small-amplitude compression deformation of the head 311, the first sealing part 3 and the second sealing part 4 can be combined and separated.

[0070] Further, see attached document. Figure 5 In some embodiments, both the first sealing layer 31 and the second sealing layer 41 are made of silicone or rubber, which can be deformed by compression.

[0071] Specifically, in order to achieve stable adhesion between the first sealing layer 31 and the second sealing layer 41, the technical solution adopted in this application uses silicone or rubber material for the sealing layer, which can undergo elastic deformation during compression. During the assembly of the second sealing layer 41 into the assembly groove 53, the second sealing layer 41 is briefly compressed by the compression head 311 of the first ring plate 51 and the second ring plate 52. After entering the assembly groove 53, the external extrusion pressure disappears, and the head 311 of the second sealing layer 41 returns to its original shape and tightly adheres to the neck 312 of the first sealing layer 31 on the first ring plate 51 and the second ring plate 52. By using silicone or rubber material, it is not only convenient for the first sealing part 3 and the second sealing part 4 to be joined and separated, but also to achieve better sealing function.

[0072] Further, see attached document. Figure 6 In some embodiments, the end face of the mounting platform 1 is provided with grooves 7 at intervals.

[0073] Specifically, to achieve a dry environment within the containment space, the technical solution adopted in this application includes several grooves 7 on the end face. These grooves 7 are used to store desiccant, which absorbs moisture within the space. This prevents moisture from entering the containment space during the opening and closing of the housing 2 to install monitoring equipment, thus avoiding any impact on the monitoring equipment. Storing the desiccant in the grooves 7 also facilitates its replacement, preventing it from becoming saturated with water and affecting the drying effect.

[0074] Furthermore, in some embodiments, the outer surface of the housing 2 is coated with a Teflon coating. Specifically, in order to ensure that the housing 2 does not affect the acquisition of monitoring images in rainy environments, the technical solution adopted in this application provides a Teflon coating on the outer surface of the housing 2. Teflon, scientifically known as polytetrafluoroethylene, has extremely high surface activity, making it difficult for water and other liquids to penetrate its surface, thus exhibiting waterproof properties. Moreover, the colorless coating does not affect the shooting effect of the monitoring equipment.

[0075] Further, see attached document. Figure 1-3 In some embodiments, the mounting platform 1 is provided with a first mounting part 11, and the housing 2 is provided with a second mounting part 21 corresponding to the first mounting part 11. The first mounting part 11 and the second mounting part 21 are hinged together by a pivot.

[0076] Specifically, in order to achieve the integration of the housing 2 and the mounting platform 1, the technical solution adopted in this application is to achieve this by hinged connection between the first mounting part 11 and the second mounting part 21, so as to avoid the loss of the housing 2.

[0077] Further, see attached document. Figure 7 The lower end of the installation platform 1 is hinged with three retractable legs, and the legs are equipped with feet.
