Description

Technical Field

[0001] This utility model relates to the field of grounding box technology, and in particular to a grounding box with waterproof function. Background Technology

[0002] Grounding boxes are widely used in power systems, communication base stations, industrial plants, and other scenarios as key devices to ensure the safe operation of equipment. Their core function is to reliably connect the metal casing of electrical equipment, cable shielding layers, etc., to the grounding electrode or grounding grid, forming an effective grounding loop. When equipment experiences abnormal conditions such as leakage or lightning strikes, it can quickly conduct current to the ground, preventing equipment damage or electric shock accidents.

[0003] However, traditional grounding boxes often use a single rubber gasket or a simple plug between the cable and the wire hole, which is difficult to accommodate the slight difference between the outer diameter of the cable and the inner diameter of the wire hole. This can easily create gaps between the two, allowing moisture to seep into the box through the gaps.

[0004] For example, in the grounding box of an outdoor communication base station, the cable passage is sealed with a regular rubber plug. During installation, the outer diameter of the cable is slightly smaller than the inner diameter of the plug, leaving a small gap between them, which allows rainwater and moisture to seep into the box. Utility Model Content

[0005] This utility model discloses a grounding box with waterproof function, which aims to solve the technical problem that traditional grounding boxes often use a single rubber gasket or simple plug between the cable and the wire hole, which is difficult to adapt to the slight difference between the outer diameter of the cable and the inner diameter of the wire hole, and easily forms a gap between the two, causing moisture to seep into the box through the gap.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof grounding box includes a box body, a connecting pipe connected to the top outer wall of the box body, and an equipment box connected to the top outer wall of the connecting pipe. It also includes: a sealing mechanism: the sealing mechanism includes a conductive plate connected inside the box body, multiple cables evenly connected to the bottom outer wall of the conductive plate, multiple wire-passing holes provided on the bottom outer wall of the box body, the outer wall of the cables fitting against the inner wall of the wire-passing holes, a fixing pipe connected to the outer wall of the cables away from the conductive plate, multiple clamps arranged in a ring array on the outer wall of the fixing pipe away from the box body, a common cap connected to the outer walls of the fixing pipe and the multiple clamps, and a common sealing ring connected to the inner walls of the multiple clamps, the sealing ring fitting against the outer wall of the cables; and a drying mechanism: the drying mechanism is located on both inner walls of the box body.

[0008] In this design, the sealing mechanism includes a conductive plate connected inside the enclosure. The conductive plate provides installation positions for multiple cables, and multiple cables are equidistantly connected to the bottom outer wall of the conductive plate. These cables transmit current and conduct abnormal currents from the equipment to the grounding grid. Multiple through-holes are provided on the bottom outer wall of the enclosure, and the outer wall of the cable fits against the inner wall of the through-hole, providing a passage for the cable. A fixing tube is connected to the outer wall of the cable away from the conductive plate. Multiple clamping plates are arranged in a ring on the outer wall of the fixing tube away from the enclosure. These clamping plates can contract under pressure to clamp the cable. A common cap is connected to the outer walls of the fixing tube and the clamping plates. The cap, through its cooperation with the fixing tube, compresses the clamping plates to clamp the cable. A common sealing ring is connected to the inner walls of the clamping plates, and this sealing ring fits against the outer wall of the cable. The sealing ring enhances the seal between the clamping plates and the cable, preventing moisture infiltration.

[0009] In a preferred embodiment, the drying mechanism includes a fixed base connected to the inner walls of both sides of the housing. Two magnets are symmetrically distributed inside the fixed base. A magnet block is connected to the top outer wall of the magnet. The outer wall of the two magnet blocks away from the magnet is connected to the same moisture-absorbing box. Multiple dehumidification holes are evenly distributed on the top outer wall of the moisture-absorbing box.

[0010] In this solution, the drying mechanism includes fixed seats connected to the inner walls on both sides of the box. The fixed seats provide installation positions for the magnets and the moisture-absorbing box, and play a fixed support role. At this time, there are two magnets symmetrically distributed inside the fixed seats. The magnets attract each other with the magnet block connected to the top outer wall of the fixed seats, thereby fixing the moisture-absorbing box at the other end of the magnet block. At this time, moisture-absorbing material is placed inside the moisture-absorbing box to absorb the moisture inside the box. At this time, there are multiple dehumidification holes evenly distributed on the top outer wall of the moisture-absorbing box. The dehumidification holes allow the humid air inside the box to enter the moisture-absorbing box and come into contact with the moisture-absorbing material inside, thereby keeping the inside of the box dry.

[0011] As described above, a waterproof grounding box includes a box body, a connecting pipe connected to the top outer wall of the box body, and an equipment box connected to the top outer wall of the connecting pipe. It also includes: a sealing mechanism: the sealing mechanism includes a conductive plate connected to the inside of the box body, multiple cables evenly connected to the bottom outer wall of the conductive plate, multiple wire-passing holes on the bottom outer wall of the box body, the outer wall of the cables fitting against the inner wall of the wire-passing holes, a fixing pipe connected to the outer wall of the cables away from the conductive plate, multiple clamps arranged in a ring on the outer wall of the fixing pipe away from the box body, a common cap connected to the outer walls of the fixing pipe and the multiple clamps, and a common sealing ring connected to the inner walls of the multiple clamps, the sealing ring fitting against the outer wall of the cables; and a drying mechanism: the drying mechanism is located on both inner walls of the box body. The waterproof grounding box provided by this utility model improves the sealing between the cables and the wire-passing holes, preventing water leakage, and maintains internal dryness by absorbing moisture from the air in the box.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] The waterproof grounding box disclosed in this utility model is mainly used in scenarios where traditional grounding boxes often use a single rubber gasket or a simple plug between the cable and the wire hole. This makes it difficult to accommodate the slight difference between the outer diameter of the cable and the inner diameter of the wire hole, which can easily create gaps between the two, allowing moisture to seep into the box through the gaps.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A waterproof grounding box includes a box body 1, a connecting pipe 5 connected to the top outer wall of the box body 1, and an equipment box 6 connected to the top outer wall of the connecting pipe 5. It also includes: a sealing mechanism: the sealing mechanism includes a conductive plate 8 connected inside the box body 1, multiple cables 7 equidistantly connected to the bottom outer wall of the conductive plate 8, multiple wire-passing holes on the bottom outer wall of the box body 1, the outer wall of the cables 7 fitting against the inner wall of the wire-passing holes, a fixing pipe 15 connected to the outer wall of the cable 7 away from the conductive plate 8, multiple clamping plates 16 arranged in a ring on the outer wall of the fixing pipe 15 away from the box body 1, a common cap 9 connected to the outer walls of the fixing pipe 15 and the multiple clamping plates 16, and a common sealing ring 17 connected to the inner walls of the multiple clamping plates 16, the sealing ring 17 fitting against the outer wall of the cable 7; and a drying mechanism: the drying mechanism is located on both inner walls of the box body 1.

[0021] The sealing mechanism includes a conductive plate 8 connected inside the housing 1. The conductive plate 8 provides installation positions for multiple cables 7. Multiple cables 7 are equidistantly connected to the bottom outer wall of the conductive plate 8. The cables 7 are used to transmit current, conducting abnormal currents of the equipment to the grounding grid. Multiple through-holes are provided on the bottom outer wall of the housing 1, and the outer wall of the cables 7 is fitted against the inner wall of the through-holes, providing a passage for the cables 7 to pass through. A fixing tube 15 is connected to the outer wall of the cable 7 on the side away from the conductive plate 8. The fixing tube 15 is located at... Multiple clamping plates 16 are arranged in a ring on the outer wall of one side away from the housing 1. The clamping plates 16 can contract when subjected to force, thereby clamping the cable 7. The fixing tube 15 and the outer wall of the multiple clamping plates 16 are connected to the same cap 9. The cap 9, through cooperation with the fixing tube 15, squeezes the clamping plates 16 to clamp the cable 7. At this time, the inner wall of the multiple clamping plates 16 is connected to the same sealing ring 17. At the same time, the sealing ring 17 is attached to the outer wall of the cable 7. The sealing ring 17 is used to enhance the sealing between the clamping plates 16 and the cable 7 and prevent moisture from seeping in.

[0022] The outer wall of the box body 1 is connected to a door 2. The outer walls of the box body 1 and the door 2 are connected to a waterproof gasket 3 that fits together. The waterproof gasket 3 prevents water from entering through the gap between the box body 1 and the door 2.

[0023] Specifically, multiple fixing tubes 15 are integrally welded to the housing 1. The outer wall of the fixing tube 15 and the inner wall of the cap 9 are provided with matching threaded grooves. The integrally welded multiple fixing tubes 15 and housing 1 are used to ensure the firmness and sealing of the connection between the fixing tube 15 and housing 1. At the same time, the outer wall of the fixing tube 15 and the inner wall of the cap 9 are provided with matching threaded grooves. The threaded grooves are used to achieve the fixed connection between the fixing tube 15 and the cap 9.

[0024] Specifically, the clamping plate 16 is made of elastic material, and the inner diameter of the end of the cap 9 closest to the box 1 is slightly larger than the inner diameter of the other end of the cap 9, so that the cap 9 can gradually squeeze the clamping plate 16 during the tightening process, thereby enhancing the sealing effect.

[0025] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the drying mechanism includes a fixing seat 12 connected to the inner walls of both sides of the housing 1. Two magnets 19 are symmetrically distributed inside the fixing seat 12. A magnet block 18 is connected to the top outer wall of the magnet 19. The outer wall of the two magnet blocks 18 away from the magnet 19 is connected to the same moisture absorption box 13. A plurality of dehumidification holes 20 are evenly distributed on the top outer wall of the moisture absorption box 13.

[0026] The drying mechanism includes a fixing seat 12 connected to the inner walls of both sides of the box 1. The fixing seat 12 provides an installation position for the magnet 19 and the moisture absorption box 13, and plays a fixed support role. At this time, two magnets 19 are symmetrically distributed inside the fixing seat 12. The magnets 19 attract each other with the magnet block 18 connected to its top outer wall, thereby fixing the moisture absorption box 13 at the other end of the magnet block 18. At this time, moisture-absorbing material is placed inside the moisture absorption box 13 to absorb the moisture in the box 1. At this time, multiple dehumidification holes 20 are evenly distributed on the top outer wall of the moisture absorption box 13. The dehumidification holes 20 allow the humid air in the box 1 to enter the moisture absorption box 13 and come into contact with the internal moisture-absorbing material, thereby keeping the inside of the box 1 dry.

[0027] The moisture-absorbing box 13 has a humidity indicator plate 14 connected to the outer wall of the side away from the conductive plate 8. The humidity indicator plate 14 can intuitively display the moisture absorption degree of the moisture-absorbing box 13 and indicate whether the moisture-absorbing material needs to be replaced.

[0028] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, a busbar 10 is connected to the bottom outer wall of the equipment box 6. The busbar 10 passes through the inner wall of the connecting pipe 5. Multiple connecting plates 11 are connected at equal intervals on one side outer wall of the busbar 10. The outer wall of the multiple connecting plates 11 away from the busbar 10 is connected to the same conductive plate 8. A current sensor 4 is connected to the end of the busbar 10 away from the equipment box 6.

[0029] A busbar 10 is connected to the bottom outer wall of the equipment box 6. The busbar 10 is used to collect current from multiple current paths and achieve centralized conduction. At this time, the busbar 10 passes through the inner wall of the connecting pipe 5. The connecting pipe 5 provides a passage for the busbar 10 and also plays a role in protection and fixation. At the same time, multiple connecting plates 11 are connected at equal intervals on one side of the outer wall of the busbar 10. The connecting plates 11 connect the busbar 10 to the conductive plate 8 to transfer current. The outer wall of the multiple connecting plates 11 away from the busbar 10 is connected to the same conductive plate 8. The conductive plate 8 receives the current conducted by the connecting plates 11 and conducts it into the grounding system. A current sensor 4 is connected to the end of the busbar 10 away from the equipment box 6. The current sensor 4 is used to detect the current magnitude on the busbar 10 and provide feedback on the current status.

[0030] Working Principle: During use, the current inside the equipment box 6 is gathered through the busbar 10 connected to the bottom and transmitted to the inside of the box 1 via the connecting pipe 5. At this time, the current sensor 4 connected to the end of the busbar 10 detects the magnitude, waveform, and trend of the conducted current in real time and feeds the data back to the external control system. This allows for the timely detection of abnormalities such as overcurrent and leakage, providing a basis for equipment fault diagnosis. Multiple connecting plates 11, equidistantly connected to one side of the outer wall of the busbar 10, conduct the current to the same conductive plate 8. The conductive plate 8 is located inside the box 1, and multiple cables 7, equidistantly connected to its bottom outer wall, further transmit the current. The cables 7 extend out through the wire holes on the bottom outer wall of the box 1, ultimately conducting the current to the grounding grid, completing the discharge of abnormal current. At this time, the cables 7 are away from the conductive plate. The fixing tube 15 connected to the outer wall of one side of the plate 8 is connected to the cap 9 through matching threaded grooves. When the cap 9 is tightened, it squeezes multiple elastic clamps 16 on one side of the fixing tube 15, thereby causing the clamps 16 to contract. This causes the sealing rings 17 installed on the inner walls of the multiple clamps 16 to fit tightly against the outer wall of the cable 7, preventing moisture from seeping in through the wire hole. At the same time, the waterproof gaskets 3 between the box body 1 and the box door 2 prevent moisture from entering through the gap between them. Next, the fixing seats 12 on both sides of the inner wall of the box body 1 fix the moisture-absorbing box 13 by the attraction between the magnets 19 and the magnet blocks 18 inside. At this time, the moisture-absorbing material in the moisture-absorbing box 13 absorbs the moisture in the box body 1 through the dehumidification hole 20 at the top of the moisture-absorbing box 13, keeping the inside dry. When the moisture-absorbing material absorbs a high degree of moisture, the humidity indicator plate 14 on the moisture-absorbing box 13 will give a prompt, thereby facilitating timely replacement.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
