Description

Technical Field

[0001] This invention relates to the field of cable branch box base frame technology, specifically a modular base assembly structure for cable branch boxes. Background Technology

[0002] Cable branch boxes are electrical devices used for cable line branching, connection, and circuit conversion. They mainly serve the functions of cable branching and conversion, realizing power distribution, and transferring or branching cables. They are suitable for scenarios with small-capacity independent load distribution and are widely used in cable distribution network projects, such as 10kV cable system nodes, urban streets, industrial parks, and residential areas.

[0003] Currently, outdoor areas frequently experience rain and water accumulation, which can easily cause the bottom of cable distribution boxes to be submerged, posing a safety hazard. Generally, a base needs to be installed at the bottom of the cable distribution box. The cable distribution box is mainly fixed to the base using bolts or other methods. At the same time, it is necessary to ensure the sealing of the connection between the base and the distribution box. However, since cable distribution boxes are mainly used outdoors, the sealed connection ages quickly under high temperature and rain conditions. Over time, its sealing performance will be affected, and the protection level of the connection between the cable distribution box and the base cannot be guaranteed. In addition, the existing cable distribution box has a large contact surface at the connection with the base, which affects the heat dissipation at the bottom. Summary of the Invention

[0004] In view of the shortcomings of existing cable branch box bases mentioned in the background art during use, the present invention provides a modular cable branch box base assembly structure, which has the advantages of high heat dissipation efficiency and good sealing performance, thus solving the technical problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a modular base assembly structure for a cable branch box, including a base, the middle of the top of the base is a hollow structure, a lifting component is installed inside the base, a support frame is connected to the top of the lifting component, a sealing frame is inserted into the top of the support frame, and the top of the sealing frame contacts the bottom of the cable branch box, a telescopic component installed inside the base is arranged on the outside of the lifting component, and the telescopic component and the lifting component are internally connected, and a door panel is provided on the side of the base.

[0006] Furthermore, the outer side of the base is symmetrically provided with slots for limiting the assembly of the frame, and a support platform is provided on the top of the base. A cable branch box is placed on the top of the support platform to support the cable branch box. A guide channel is provided on the outer side of the support platform, which is located on the base. The bottom of the guide channel is sloping, and the outer side of the sloping surface is closer to the ground, which can avoid the problem of external rainwater retention and reduce erosion.

[0007] Furthermore, an assembly frame is inserted into the slot, and the assembly frame covers the outside of the base and the cable branch box fixing bolts. A fastener is inserted into the other end of the assembly frame, which also covers the outside of the connecting bolts. The inner side of the assembly frame is located above the guide channel, which can protect the connecting bolts, reduce the erosion of external rainwater, and extend their service life.

[0008] Furthermore, the sealing frame is a rectangular frame with a limiting groove at the bottom. The limiting groove is movably fitted onto the outside of the support frame, and a sealing ring is connected to the top of the sealing frame. The sealing ring is made of elastic rubber and its top is higher than the top of the support platform, so that the sealing frame can seal with the bottom of the cable branch box and enhance the sealing effect by means of its deformation.

[0009] Furthermore, the lifting components are symmetrically arranged inside the base, the movable end of the top of the lifting components is connected to the support frame, and the lifting components are filled with a stable gas. The interior of the lifting components is sealed, and the interior of the lifting components can also be filled with a stable liquid.

[0010] Furthermore, the telescopic component has an arc-shaped structure, and the center of the telescopic component is coaxial with the rotation axis of the door panel. The telescopic component is located outside the lifting component, and the top of the telescopic component is lower than the top height of the lifting component when it is retracted, so as to avoid the telescopic component affecting the vertical movement of the support frame. The telescopic component is connected to a connecting pipe inside, and the other end of the connecting pipe is connected to the inside of the lifting component, so that the lifting component can shorten when the telescopic component extends, and the lifting component can extend when the telescopic component shortens. The movable end of the telescopic component is movably connected to the inside of the door panel through a hinge. The distance between the two telescopic components is greater than the width of the sealing frame, ensuring that the sealing frame can be easily put on and taken off.

[0011] Furthermore, the width of the door panel is greater than the width of the sealing frame, and the top of the door panel is higher than the top position of the lifting component when it is shortened, which facilitates the removal and placement of the sealing frame. The top of the door panel is movably connected to the base through a hinge, and the door panel has an outward tilting structure.

[0012] Furthermore, the limiting plate is installed on the outside of the base via a damping pivot, and the limiting plate is located on one side of the door panel. The outer end of the limiting plate is an outwardly curved arc structure, which facilitates the rotation of the limiting plate when the door panel is closed. At the same time, the limiting plate can also be used to close the door panel, which is convenient for manual operation. Moreover, the limiting plate can coincide with the door panel by rotating, thus closing the door panel.

[0013] The present invention has the following beneficial effects: 1. This invention provides a side-opening door on the side of the base of the cable branch box. With the cooperation of pneumatic or hydraulic linkage components, the base is assembled and sealed. When the side door is opened, the internal seal can be lowered, making it easy to replace. When the side door is closed, the seal can be raised, achieving a seal between the cable branch box and the base, ensuring the reliability of the seal between the two, and also facilitating manual operation.

[0014] 2. By setting up a liftable sealing element and a frame-shaped platform specifically designed to support the cable branch box on the top of the base, the present invention can greatly reduce the contact area between the cable branch box and the base, thereby accelerating heat dissipation and avoiding the problem of large contact area between the traditional base and the box, which affects heat dissipation.

[0015] 3. By setting a guide channel at the connection between the base and the cable branch box, and with the cooperation of an external plug-in baffle, the present invention can reduce the retention of external rainwater, reduce the erosion of the base connection by the external environment, and extend the overall service life of the base assembly structure.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 A modular base assembly structure for a cable branch box includes a base 1. The top center of the base 1 is hollow, which reduces contact with the cable branch box and facilitates heat dissipation from the cable branch box. (See reference...) Figure 4 The base 1 has symmetrical slots 101 on its outer side for assembling the frame 7 and a support platform 103 on its top. A cable branch box is placed on the top of the support platform 103 to support the cable branch box. A guide channel 102 is provided on the outer side of the support platform 103. The bottom of the guide channel 102 is sloping, and the outer side of the sloping surface is closer to the ground to avoid the problem of rainwater retention and reduce erosion.

[0020] Please see Figure 2 The slot 101 is fitted with an assembly frame 7, which covers the outside of the base 1 and the cable branch box fixing bolts. The other end of the assembly frame 7 is fitted with a fastener 71, which also covers the outside of the connecting bolts. The inner side of the assembly frame 7 is located above the guide channel 102, which can protect the connecting bolts, reduce the erosion of external rainwater, and extend their service life.

[0021] Please see Figure 4 The sealing frame 4 is a rectangular frame, see reference. Figure 5 The bottom of the sealing frame 4 has a limiting groove 41, which is movably fitted onto the outside of the support frame 2. The top of the sealing frame 4 is connected to a sealing ring, which is made of elastic rubber. The top of the sealing ring is higher than the top of the support platform 103, so that the sealing frame 4 can seal with the bottom of the cable branch box. The deformation of the sealing frame enhances the sealing effect. By movably inserting the sealing frame 4, and with the cooperation of the telescopic component 5 and the lifting component 3, the assembled sealing structure of the cable branch box base is realized. This facilitates the periodic replacement of the sealing ring, thereby maintaining the sealing performance of the connection between the cable branch box and the base and reducing malfunctions. At the same time, the forces between the assembled sealing structure and the base, the forces inside the lifting component 3 and the telescopic component 5, and the forces between the door panel 6 and the limiting plate 8 can ensure the sealing performance of the sealing frame 4 and the stability of the door panel 6 after it is closed, thus improving the practicality of the cable branch box base structure.

[0022] Please see Figure 3The base 1 houses a lifting component 3, which is a sealed piston rod structure. A support frame 2 is connected to the top of the lifting component 3. The grid structure of the support frame 2 ensures overall stability and facilitates grounding connection without affecting heat dissipation. A sealing frame 4 is inserted into the top of the support frame 2, with its top contacting the bottom of the cable distribution box. A telescopic component 5, installed inside the base 1, is located on the outside of the lifting component 3, and the telescopic component 5 communicates with the interior of the lifting component 3. The lifting components 3 are symmetrically arranged inside the base 1. (See reference...) Figure 8 The movable end of the top of the lifting component 3 is connected to the support frame 2, and the interior of the lifting component 3 is filled with a stable gas. The interior of the lifting component 3 is sealed. The interior of the lifting component 3 can also be filled with a stable liquid. (See reference...) Figure 7 The telescopic component 5 has an arc-shaped structure and is capable of movable extension and retraction. The center of the telescopic component 5 is coaxial with the rotation axis of the door panel 6. The telescopic component 5 is located outside the lifting component 3, and the top of the telescopic component 5 is lower than the top height of the lifting component 3 when it is retracted, so as to avoid the telescopic component 5 affecting the vertical movement of the support frame 2. The telescopic component 5 is connected to a connecting pipe 51 inside, and the other end of the connecting pipe 51 is connected to the inside of the lifting component 3, so that the lifting component 3 can be shortened when the telescopic component 5 is extended, and the lifting component 3 can be extended when the telescopic component 5 is shortened. The movable end of the telescopic component 5 is movably connected to the inside of the door panel 6 through a hinge. The distance between the two telescopic components 5 is greater than the width of the sealing frame 4, ensuring that the sealing frame 4 can be easily put on and taken off.

[0023] Please see Figure 2 A door panel 6 is provided on the side of the base 1. The width of the door panel 6 is greater than the width of the sealing frame 4, and the top of the door panel 6 is higher than the top position of the lifting component 3 when it is shortened, which facilitates the removal and placement of the sealing frame 4. The top of the door panel 6 is movably connected to the base 1 through a hinge, and the door panel 6 has an outward deflection structure. The limiting plate 8 is installed on the outside of the base 1 through a damping pivot, and the limiting plate 8 is located on one side of the door panel 6. The outer end of the limiting plate 8 has an outward curved arc structure, which facilitates the rotation of the limiting plate 8 when the door panel 6 is closed. At the same time, the limiting plate 8 can also be used to realize the closing action of the door panel 6, which is convenient for manual operation. The limiting plate 8 can coincide with the door panel 6 by rotation, so as to realize the closing of the door panel 6.

[0024] In addition, by setting the sealing and support as separate modules, the structure is modularized, and the contact area between the support structure and the ground of the cable branch box is greatly reduced, which is beneficial to the heat dissipation of the cable branch box and also facilitates later maintenance and other operations.

[0025] The working principle of this invention is as follows: The bottom of the base 1 is fixed to the installation area of ​​the cable branch box using concrete. Then, the cable branch box is fixed to the base 1 with bolts, so that the support platform 103 supports the cable branch box. Then, the assembly frame 7 is inserted into the slot 101, covering the top of the connecting bolts. Then, the fastener 71 is inserted into the other side of the assembly frame 7 to fix the assembly frame 7. At the same time, the corresponding grounding wire is connected. After being put into use, the heat generated at the bottom of the cable branch box can be directly discharged from the base 1. When the sealing ring on the sealing frame 4 ages, the deflection limit plate 8 is deflected, and then opened. Door panel 6 is deflected outwards, telescopic component 5 is stretched back, and lifting component 3 is shortened, causing sealing frame 4 to move down with support frame 2. Then, sealing frame 4 is removed, sealing ring on sealing frame 4 is replaced, and sealing frame 4 is placed back on support frame 2. Limiting groove 41 is fitted onto the top of support frame 2. Door panel 6 is closed, telescopic component 5 is shortened, and lifting component 3 is extended. Sealing frame 4 moves up with support frame 2 and abuts against the bottom of cable branch box. Then, limiting plate 8 is deflected and blocked outside door panel 6. At this time, there is an interaction force between sealing frame 4 and cable branch box, and there is also an interaction force between door panel 6 and limiting plate 8.
