Due to the humid and muggy environment inside power cable maintenance pits, the cross-connection boxes are susceptible to moisture intrusion. Moisture easily enters the box through the gap between the box body and the cover, causing moisture and flooding inside the cross-connection box, which in turn damages internal components. Summary of the Invention

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0043] The exemplary embodiments will be described in detail herein, with examples shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements, unless otherwise indicated. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0044] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their 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 at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] The high-voltage transmission cable cross-connection box is installed in the power cable maintenance pit. Since the internal environment of the power cable maintenance pit is humid and stuffy, the cross-connection box is in a humid and stuffy environment for a long time and is easily invaded by water vapor, causing the inside of the cross-connection box to become damp and soaked in water, which in turn causes the insulation board inside the cross-connection box to become damp and deteriorate, the protector to be damaged, and the connecting screws to rust.

[0048] The insulation board prevents the high-voltage cable outer sheath grounding wire from directly contacting the ground. When conducting a power-off insulation resistance test on the cable outer sheath, if the insulation board becomes damp, the test equipment connected to the ground wire can connect to the damp insulation board, creating a ground fault and ultimately affecting the test data. Excessive protector damage increases production costs. Rusted connecting screws lead to poor electrical contact, posing the risk of excessive sheath voltage damaging primary equipment.

[0049] In order to prevent the components inside the cross-connect box from being damaged by moisture, the existing method is to add a sealing ring at the connection between the cross-connect box body and the box cover to prevent water from entering the cross-connect box. However, during the process of closing the box cover, the sealing ring is easily misaligned, and water vapor can easily enter the box body through the misaligned gap. In addition, the sealing ring is prone to aging and loses its sealing function.

[0050] In order to solve the technical problem that the internal components of the existing cross-connection box are easily invaded by water vapor, an embodiment of the present application proposes a cross-connection box, including a box body, a box cover, an annular baffle and a cover plate, the box cover is closed on the box body; the annular baffle includes a first annular side wall portion and an annular bottom wall portion, the first annular side wall portion, the annular bottom wall portion and the inner wall of the box body are connected in sequence to form an annular groove, and a moisture-absorbing component is provided in the annular groove; the cover plate is provided on the side of the box cover facing the box body, and the cover plate is configured to abut against the first annular side wall portion, and the projection of the first annular side wall portion toward the cover plate is located inside the cover plate.

[0051] In the cross-connected box of the embodiment of the present application, the cover plate abuts against the first annular side wall portion, and since the projection of the first annular side wall portion toward the cover plate is located inside the cover plate, when water vapor enters the box body from the gap between the box body and the box cover, the water vapor will first pass through the annular groove, and then enter the box body through the abutment between the cover plate and the first annular side wall portion. Since a moisture-absorbing component is provided in the annular groove, when water vapor passes through the annular groove, the moisture-absorbing component will absorb the water vapor, which can prevent water vapor from further flowing into the abutment between the cover plate and the first annular side wall portion, and because the cover plate abuts against the first annular side wall portion, it can further prevent water vapor from entering the interior of the box body from between the cover plate and the first annular side wall portion, thereby avoiding In order to prevent the components inside the box from being invaded by water vapor, in the cross-connected box of the embodiment of the present application, the water vapor entering the box from the gap between the box body and the box cover first passes through the annular groove. The annular groove not only serves to extend the path for the water vapor to enter the component position inside the box, but the moisture-absorbing member in the annular groove also adsorbs the water vapor on the path, so that the water vapor on the path gradually decreases. Then, through the abutment relationship between the cover plate and the first annular side wall portion, the water vapor entering the inside of the box from between the cover plate and the first annular side wall portion is further reduced, that is, the water vapor entering from the gap between the box body and the box cover to the component position inside the box is reduced, thereby solving the technical problem that the internal components of the existing cross-connected box are easily invaded by water vapor.

[0052] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0053] In the examples of this application, refer to Figures 1 to 4As shown, an embodiment of the present application provides a cross-connect box, including a box body 100 , a box cover 200 , an annular baffle 300 and a cover plate 400 .

[0054] The interior of the box 100 is used to install components inside the cross-connection box, such as insulation boards, protectors, and connecting screws.

[0055] The box cover 200 is covered on the box body 100 .

[0056] The annular baffle 300 includes a first annular side wall portion 310 and an annular bottom wall portion 320 . The first annular side wall portion 310 , the annular bottom wall portion 320 and the inner wall of the box body 100 are sequentially connected to form an annular groove 500 . A moisture absorbent member 900 is disposed in the annular groove 500 .

[0057] The cover plate 400 is disposed on a side of the box cover 200 facing the box body 100 . The cover plate 400 is configured to abut against the first annular side wall portion 310 , and the projection of the first annular side wall portion 310 toward the cover plate 400 is located inside the cover plate 400 .

[0058] In the cross-connect box of the present embodiment, the box cover 200 is attached to the box body 100. The attachment method can be detachable or rotatably connected. The detachable attachment method uses a detachable structure to achieve flexible assembly of the box cover 200 and the box body 100, which is suitable for scenarios where frequent disassembly is required or space is limited. Specifically, bolts, latches, locking structures, etc. are used. The rotatably connected attachment method uses a hinge or connecting rod mechanism to achieve the rotation of the box cover 200 around the axis, which takes into account both sealing and ease of operation.

[0059] The annular baffle 300 includes a first annular sidewall portion 310 and an annular bottom wall portion 320. The first annular sidewall portion 310, the annular bottom wall portion 320, and the inner wall of the housing 100 are sequentially connected to form an annular groove 500. The annular groove 500 is formed on the inner wall of the housing 100. A moisture absorbent member 900 is disposed within the annular groove 500. The moisture absorbent member 900 can be a sponge, cotton fabric, a chemical moisture absorbent, a superabsorbent polymer, etc. For example, the annular groove 500 can be filled with moisture absorbent particles, such as activated carbon particles, calcium chloride particles, compressed bamboo shavings particles, silica gel particles, etc.

[0060] The cover plate 400 is arranged on the side of the box lid 200 facing the box body 100, and the cover plate 400 is in contact with the first annular side wall portion 310. At this time, the projection of the first annular side wall portion 310 toward the cover plate 400 is located inside the cover plate 400, which is equivalent to the cover plate 400 covering the annular groove 500 at this time. Therefore, when water vapor enters the box body 100 from the gap between the box body 100 and the box lid 200, the water vapor will first pass through the annular groove 500, and then enter the interior of the box body 100 through the contact point between the cover plate 400 and the first annular side wall portion 310. The interior of the box body 100 at this position is the location where the internal components of the cross-connected box are set.

[0061] In the cross-connected box of the embodiment of the present application, the cover plate 400 abuts against the first annular side wall portion 310, and since the projection of the first annular side wall portion 310 toward the cover plate 400 is located inside the cover plate 400, when water vapor enters the box body 100 from the gap between the box body 100 and the box cover 200, the water vapor will first pass through the annular groove 500, and then enter the box body 100 through the abutment between the cover plate 400 and the first annular side wall portion 310. Since a moisture absorbent member 900 is provided in the annular groove 500, when water vapor passes through the annular groove 500, the moisture absorbent member 900 will absorb the water vapor, which can prevent the water vapor from further flowing into the abutment between the cover plate 400 and the first annular side wall portion 310, and because the cover plate 400 abuts against the first annular side wall portion 310, it can further prevent water vapor from entering the box body 100 from between the cover plate 400 and the first annular side wall portion 310. , thereby preventing the components inside the box body 100 from being invaded by water vapor. In the cross-connected box of the embodiment of the present application, the water vapor entering the box body 100 from the gap between the box body 100 and the box cover 200 first passes through the annular groove 500. The annular groove 500 not only serves to extend the path for the water vapor to enter the component positions in the box body 100, but the moisture absorbent member 900 in the annular groove 500 also adsorbs the water vapor on the path, so that the water vapor on the path gradually decreases. Then, through the abutment relationship between the cover plate 400 and the first annular side wall portion 310, the water vapor entering the interior of the box body 100 from between the cover plate 400 and the first annular side wall portion 310 is further reduced, that is, the water vapor entering the component positions in the box body 100 from the gap between the box body 100 and the box cover 200 is reduced, thereby solving the technical problem that the internal components of the existing cross-connected box are easily invaded by water vapor.

[0062] In another embodiment, referring to Figure 5 and Figure 6As shown, the cover plate 400 includes an annular cover body 410, the inner ring side of the annular cover body 410 is arranged on the box cover 200, and the annular cover body 410 is inclined toward the annular groove 500 from the inner ring side of the annular cover body 410 to the outer ring side of the annular cover body 410, and the annular cover body 410 is configured so that the projection of the outer ring side of the annular cover body 410 toward the annular groove 500 is located within the annular groove 500.

[0063] In this embodiment, when water vapor enters the box body 100 from the gap between the box body 100 and the box cover 200, part of the water vapor will pass through the upper surface of the annular cover body 410, and the other part of the water vapor will pass through the lower surface of the annular cover body 410. Because the annular cover body 410 is inclined from the inner ring side of the annular cover body 410 to the outer ring side of the annular cover body 410 toward the annular groove 500, and the projection of the outer ring side of the annular cover body 410 toward the annular groove 500 is located in the annular groove 500, the water vapor on the upper surface of the annular cover body 410 will be drawn by the annular cover body 410 due to gravity. The annular cover body 410 guides the water vapor into the annular groove 500, thereby being absorbed by the wet parts in the annular groove 500. The annular cover body 410 plays a role of guiding the water vapor, and the other part of the water vapor passing through the lower surface of the annular cover body 410 will naturally be absorbed by the wet parts in the annular groove 500. Therefore, the water vapor entering the box body 100 from the gap between the box body 100 and the box cover 200 will first pass into the annular groove 500, and can be absorbed by the wet parts in the annular groove 500, that is, the water vapor entering the parts in the box body 100 from the gap between the box body 100 and the box cover 200 is further reduced.

[0064] In certain embodiments, reference Figure 5 and Figure 6 As shown, a hydrophobic layer 600 is provided on the surface of the annular cover 410 facing the box cover 200 .

[0065] In this embodiment, because the hydrophobic layer 600 is provided on the side of the annular cover body 410 facing the box cover 200, the water droplets on the side of the annular cover body 410 facing the box cover 200 will not be adsorbed on the annular cover body 410 in large quantities. Most of them will be diverted into the annular groove 500 due to gravity and will eventually be absorbed by the wet parts in the annular groove 500, thereby ensuring the dryness inside the box body 100.

[0066] The hydrophobic layer 600 can be provided by coating a hydrophobic coating on the surface of the annular cover 410 facing the box cover 200, or by processing the surface of the annular cover 410 facing the box cover 200 so that the surface of the annular cover 410 facing the box cover 200 forms a hydrophobic surface. The specific method is as follows:

[0067] The surface of the annular cover 410 facing the box cover 200 is scanned by laser processing to form a rough structure on the surface of the annular cover 410 facing the box cover 200;

[0068] Then, a low surface energy liquid is used for immersion or vapor deposition, so that a super-hydrophobic surface is formed on the surface of the annular cover 410 facing the box cover 200. This super-hydrophobic surface is the hydrophobic layer 600.

[0069] The super-hydrophobic surface achieves extreme hydrophobic properties with a contact angle greater than 150° and a rolling angle less than 10° through a combination of special micro-nano rough structures and low surface energy chemicals. It is waterproof and moisture-proof, so that water droplets attached to or dripping on the surface of the annular cover 410 facing the box cover 200 will slide into the annular groove 500 due to gravity.

[0070] In another possible embodiment, referring to Figure 5 and Figure 6 As shown, at least one guide groove 700 is provided on the hydrophobic layer 600 along the circumference of the annular cover 410 , and a hydrophilic layer 710 is provided in the guide groove 700 .

[0071] In this embodiment, part of the water droplets on the hydrophobic layer 600 will slide into the annular groove 500 due to gravity, and the other part can be adsorbed by the hydrophilic layer 710 to avoid residual water droplets on the hydrophobic layer 600. Finally, the water droplets on the surface of the hydrophilic layer 710 will also slide into the annular groove 500 due to gravity.

[0072] The hydrophilic layer 710 can be provided by coating a hydrophilic coating in the guide groove 700, or by processing the surface of the annular cover 410 facing the box cover 200 so that the surface of the annular cover 410 facing the box cover 200 forms a hydrophobic surface. The specific method is as follows:

[0073] The surface of the annular cover 410 facing the box cover 200 is scanned by laser processing to form a rough structure on the surface of the annular cover 410 facing the box cover 200;

[0074] Then, a low surface energy liquid is used for immersion or vapor deposition, so that the surface of the annular cover 410 facing the box cover 200 forms a super-hydrophobic surface, which is the hydrophobic layer 600;

[0075] Then, laser patterning is performed on the super-hydrophobic surface to form a super-hydrophilic pattern, which is the hydrophilic layer 710 .

[0076] The main difference between a super-hydrophobic surface and a super-hydrophilic surface is the surface energy. The surface energy of a super-hydrophobic surface is extremely low, which can quickly allow water vapor to form water balls, which are then captured and gathered by the super-hydrophilic surface and eventually flow into the annular groove 500.

[0077] In other possible embodiments, refer to Figure 3 、 Figure 7 and Figure 8As shown, an annular partition 800 is arranged in the annular groove 500, and the annular partition 800 includes an annular plate body 810 and at least one supporting foot 820, each supporting foot 820 is arranged on the annular plate body 810, and the annular plate body 810 is arranged on the bottom wall of the annular groove 500 through each supporting foot 820, and a gap is formed between the annular plate body 810 and the bottom wall of the annular groove 500, and the annular plate body 810 is configured so that the projection toward the cover plate 400 is located inside the cover plate 400.

[0078] In this embodiment, when water vapor enters the box body 100 through the gap between the box body 100 and the box cover 200, the water vapor will first enter the side of the annular groove 500 close to the inner wall of the box body 100 from top to bottom, and then flow to the side of the annular groove 500 away from the inner wall of the box body 100. During the flow, there is an annular partition 800 to block it. Part of the water vapor will flow from the gap between the annular plate body 810 and the bottom wall of the annular groove 500 to the side of the annular groove 500 away from the inner wall of the box body 100, and then flow from bottom to top to the abutment between the cover plate 400 and the first annular side wall portion 310, and finally enter the component position inside the box body 100 through the abutment between the cover plate 400 and the first annular side wall portion 310. In this process, the path for water vapor to flow into the component position inside the box body 100 is extended, and the path fluctuates up and down. In addition, a moisture-absorbing member 900 is provided in the path, which greatly reduces the water vapor entering the component position.

[0079] In other embodiments, reference Figure 6 As shown, it also includes a connecting ring body 420, which is arranged on the inner ring side of the annular cover body 410, and the annular cover body 410 is arranged on the box cover 200 through the connecting ring body 420.

[0080] Specifically, the connecting ring body 420 can be fixed to the box cover 200 by welding or bonding.

[0081] In another embodiment, referring to Figure 3 、 Figure 7 and Figure 8 As shown, the annular plate body 810 is configured to abut against the cover plate 400 .

[0082] In this embodiment, the annular plate 810 is in contact with the cover plate 400, that is, at this time, water vapor cannot pass through the contact between the annular plate 810 and the cover plate 400, and water vapor can only pass through the bottom of the annular plate 810. Therefore, the process for water vapor to enter the interior of the box body 100 is that the water vapor will first enter from the top to the bottom to the side of the annular groove 500 close to the inner wall of the box body 100, and then the water vapor will flow from the gap between the annular plate 810 and the bottom wall of the annular groove 500 to the side away from the annular groove 500. One side of the inner wall of the box body 100, and then flows from bottom to top to the joint between the cover plate 400 and the first annular side wall portion 310, and finally enters the component position inside the box body 100 through the joint between the cover plate 400 and the first annular side wall portion 310. In this process, the water vapor first flows from top to bottom into the annular groove 500, and then flows out of the annular groove 500 from top to bottom, extending the path of the water vapor flowing into the component position inside the box body 100, thereby increasing the probability of the water vapor being adsorbed by the hygroscopic component 900.

[0083] In another possible embodiment, referring to Figure 3 、 Figure 7 and Figure 8 As shown, the annular baffle 300 further includes a second annular side wall portion 330 , and the annular bottom wall portion 320 is connected to the inner wall of the box body 100 via the second annular side wall portion 330 , so that the second annular side wall portion 330 forms the outer annular wall of the annular groove 500 .

[0084] In this embodiment, the second annular side wall portion 330 forms the outer annular wall of the annular groove 500 , thereby ensuring the stability of the annular baffle 300 being fixed to the inner wall of the box body 100 .

[0085] The second annular side wall portion 330 may be fixed to the inner wall of the box body 100 by welding, clamping, bonding, etc.

[0086] Further, refer to Figure 3 As shown, the height of the first annular side wall portion 310 is lower than the height of the inner wall of the box body 100 .

[0087] Further, refer to Figure 3 As shown, the height of the annular partition 800 is lower than that of the first annular sidewall portion 310 , and the height of the second annular sidewall portion 330 is lower than that of the annular partition 800 .
