Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a device for sealing the cable passage holes of a switchgear. Background Technology

[0002] Substation switchgear typically has cable exit holes at the bottom for easy entry of cables from cable trenches into the switchgear. Because switchgear models vary in size and cannot be specifically designed for a particular cable type, the cable exit holes are usually quite large, resulting in gaps between the exit holes and the cables. If these gaps are not sealed, dust, debris, rodents, and other small animals can enter the switchgear through them. This can cause the switchgear to trip, or even burn out and damage the equipment, leading to power equipment accidents and potentially large-scale power outages.

[0003] Currently, sealing mud is generally used for sealing. During construction, the holes to be sealed are first cleaned, and then the sealing mud is kneaded into a ball and evenly spread, embedded, and filled into the gaps in the holes. However, this operation has low construction efficiency, and after long-term use, the sealing mud is prone to collapse and fall off, which means that the safe operation of the switchgear still has great hidden dangers. Summary of the Invention

[0004] The purpose of this invention is to provide a switch cabinet wire hole sealing device, which has a simple structure, can effectively seal wire holes, and has good applicability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for sealing cable passage holes in a switchgear is provided, comprising a sealing plate and a connecting plate. Two sealing plates are provided. Each sealing plate includes a connecting seat, a molding plate, and a locking member. The molding plate is composed of multiple parallel molding teeth, which are movably disposed on the connecting seat so that the molding plate can form a clearance notch according to the shape of the cable in the cable passage hole. The locking member is used to lock the molding teeth. The two sealing plates are spliced ​​together by the connecting member so that the clearance notches of the two sealing plates form a clearance hole for the cable to pass through.

[0007] As a preferred embodiment of the switch cabinet cable hole sealing device, the connecting seat is provided with a strip-shaped first through hole, and the connecting seat is sleeved on the molding plate through the first through hole. When the locking member is unlocked, the molding tooth can move in the first through hole along the first direction.

[0008] As a preferred embodiment of the switch cabinet cable hole sealing device, the forming tooth includes a tooth body, and both ends of the tooth body along the first direction are provided with limit blocks. The limit blocks can abut against the side wall of the connecting seat to prevent the forming tooth from disengaging from the connecting seat.

[0009] As a preferred embodiment of the switch cabinet cable hole sealing device, the forming teeth further include a slide rail, the two ends of which are respectively connected to two limiting blocks. The slide rail is parallel to and spaced apart from the tooth body, and the connecting seat is sleeved on the outer periphery of the slide rail of all the forming teeth.

[0010] As a preferred embodiment of the switch cabinet cable hole sealing device, a second through hole is provided through the wall of the first through hole. The locking component includes a push plate, a connecting rod, and an eccentric wheel. A rotating shaft is provided in the second through hole. The eccentric wheel is rotatably mounted on the rotating shaft. One end of the connecting rod is hinged to the push plate, and the other end is connected to the eccentric wheel. Rotating the eccentric wheel can drive the push plate to move along a second direction, which is perpendicular to the first direction.

[0011] The eccentric wheel has a locked position and an unlocked position. When the eccentric wheel is in the locked position, the push plate abuts against the forming tooth to restrict the movement of the forming tooth. When the eccentric wheel rotates to the unlocked position, the push plate moves away from the forming tooth, and the forming tooth can move along the first direction.

[0012] As a preferred embodiment of the switchgear cable hole sealing device, the eccentric wheel is provided with a first elastic element, which always has the tendency to drive the eccentric wheel to rotate toward the locking position.

[0013] As a preferred embodiment of the switchgear cable hole sealing device, the connector includes a sleeve, a second elastic element and two hooks. One end of each of the two hooks is movably disposed within the sleeve, and the other end is respectively engaged with the connecting seat of each of the two sealing plates. The second elastic element is disposed within the sleeve, and both ends of the second elastic element are respectively connected to the two hooks, so that the two hooks have a tendency to move relative to each other.

[0014] As a preferred embodiment of the switchgear cable hole sealing device, the connecting seat is provided with a slot, and the hook is inserted into the slot.

[0015] As a preferred embodiment of the switchgear cable hole sealing device, the connector includes a telescopic rod, one end of which is provided with a fixing hole and a fastener is provided in the fixing hole. The end of the telescopic rod away from the fixing hole is rotatably connected to the connecting seat, and the other end can be connected to the connecting seat of any of the sealing plates through the fastener.

[0016] As a preferred embodiment of the cable hole sealing device for switchgear, the sealing plate is provided with a magnetic suction component, which is used to fix the sealing plate inside the switchgear.

[0017] The beneficial effects of this invention are as follows: When sealing the cable passage holes of a switchgear, two sealing plates are spliced ​​together along the opposite sides of the cable in the passage hole to seal it. Simultaneously, the locking mechanism unlocks the forming teeth. During splicing, the spliced ​​end abuts against the cable, allowing the forming teeth to move away from the cable and form clearance holes that match the cable's shape. Then, the two sealing plates are held in the spliced ​​state by a connector, and the forming teeth are locked by the locking mechanism to prevent movement of the forming teeth and sealing failure. This sealing device can seal the cable passage holes by splicing, preventing small animals or other foreign objects from entering the switchgear. It is simple to operate, improves sealing efficiency, and can be supported on the switchgear's base plate without collapsing or falling off. It provides good sealing and automatically forms clearance holes according to different cable shapes, making it highly adaptable. Attached Figure Description

[0030] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail 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.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The bottom plate of the switchgear has through holes for cables to pass through. A cable hole sealing device is installed on the bottom plate of the switchgear to seal the through holes on the bottom plate of the switchgear.

[0033] like Figure 1 As shown, the present invention provides a switch cabinet cable hole sealing device including a sealing plate 1 and a connector 2. Two sealing plates 1 are provided. The sealing plate 1 includes a connecting seat 11, a molding plate 12 and a locking member 13. The molding plate 12 is composed of a plurality of parallel molding teeth 121. The molding teeth 121 are movably disposed on the connecting seat 11 so that the molding plate 12 can move along a first direction according to the shape of the cable 100 on the cable hole and form an avoidance gap. The locking member 13 is used to lock the molding teeth 121. The two sealing plates 1 are spliced ​​together by the connector 2. The sealing plate 1 has a splicing end, which is located on one side of the sealing plate 1 along the first direction. The two sealing plates 1 are spliced ​​together along the first direction so that the avoidance gap of the two molding plates 12 forms an avoidance hole for the cable 100 to pass through.

[0034] When it is necessary to block the cable passage holes of the switchgear, the locking member 13 unlocks the protruding teeth 121 and splices the two blocking plates 1 along the opposite sides of the cable 100 to block the cable passage holes. During the splicing process, the splicing end abuts against the cable 100, allowing the protruding teeth 121 abutting against the cable 100 to move in the first direction to form a clearance hole that matches the cable 100. Then, the two blocking plates 1 are held in the spliced ​​state by the connecting member 2, and the protruding teeth 121 are locked by the locking member 13 to prevent the protruding teeth 121 from moving and causing the blocking to fail. The blocking device designed in this way can block the cable passage holes by splicing, preventing small animals or other foreign objects from entering the switchgear through the cable passage holes. It is simple to operate, can improve the blocking efficiency, and the bottom plate of the switchgear can support the blocking device. The blocking device will not collapse, fall off or fail, and has high stability and good blocking effect. Moreover, it can automatically form clearance holes according to the shape of different cables 100, making it highly applicable.

[0035] The sealing device is made of insulating and fireproof materials.

[0036] In another embodiment, the sealing device is made of insulating material. After sealing, fireproof putty is applied to the sealing device to prevent fire and improve the sealing effect.

[0037] Specifically, such as Figure 2 As shown, the connecting seat 11 is provided with a strip-shaped first through hole 111. The connecting seat 11 is sleeved on the outside of the molding plate 12 through the first through hole 111. When the locking member 13 is unlocked, the molding teeth 121 can move in the first through hole 111 along the first direction. The size of the first through hole 111 can match the shape of the molding plate 12. The first through hole 111 allows the molding teeth 121 to be arranged side by side and fit together, so as to limit the molding teeth 121 from deviating in the second direction when moving in the first direction. The second direction is perpendicular to the first direction.

[0038] In one embodiment, the connecting seat 11 includes two seats that are detachably connected to form the connecting seat 11 so that the connecting seat 11 can be fitted onto the molding plate 12.

[0039] Furthermore, such as Figure 3 and Figure 4 As shown, the forming tooth 121 includes a tooth body 1211, with limiting blocks 1212 at both ends of the tooth body 1211. The two limiting blocks 1212 are arranged opposite to each other along a first direction. The two limiting blocks 1212 can keep the tooth body 1211 always on the connecting seat 11. When the tooth body 1211 moves to the point where the limiting block 1212 abuts against the side wall of the connecting seat 11, the limiting block 1212 can restrict the tooth body 1211 from moving further, preventing the forming tooth 121 from moving excessively and detaching from the connecting seat 11.

[0040] Furthermore, such as Figure 4 As shown, the tooth body 1211 is provided with a slide rail 1213. The two ends of the slide rail 1213 are respectively connected to two limit blocks 1212. The slide rail 1213 is parallel to and spaced apart from the tooth body 1211. The slide rail 1213 is located above the tooth body 1211. The slide rails 1213 of all the forming teeth 121 are parallel and side by side. The connecting seat 11 can be simultaneously fitted on the outer periphery of the slide rails 1213 of all the forming teeth 121, so that each forming tooth 121 can move relative to the first through hole 111 in the first direction. That is, the forming plate 12 forms an annular structure. The connecting seat 11 and the forming plate 12 are engaged. The lower surface of the forming plate 12 can be completely fitted with the bottom plate of the switch cabinet, which can avoid the gap between the sealing device and the bottom plate of the switch cabinet, so as to ensure the sealing effect of the sealing device.

[0041] Specifically, the sealing plate 1 is provided with a magnetic attractor (not shown in the figure), which is used to fix the sealing plate 1 to the bottom plate of the switch cabinet. In this embodiment, the magnetic attractor is a magnet, which is disposed on the connecting seat 11. The magnetic attractor can magnetically attract with the bottom plate of the switch cabinet so that the sealing device can stably seal the wire hole.

[0042] In this embodiment, as Figure 5 and Figure 6 As shown, a second through hole 112 is provided through the wall of the first through hole 111. The locking member 13 includes a push plate 131, a connecting rod 132 and an eccentric wheel 133. A rotating shaft (not shown in the figure) is provided in the second through hole 112. The eccentric wheel 133 is rotatably mounted on the rotating shaft. The push plate 131 is slidably mounted in the second through hole 112. One end of the connecting rod 132 is hinged to the push plate 131 and the other end is connected to the center of the eccentric wheel 133. Rotating the eccentric wheel 133 can drive the push plate 131 to move in the second direction.

[0043] The eccentric wheel 133 includes an unlocked position and a locked position. When the eccentric wheel 133 is in the locked position, the eccentric wheel 133 can drive the push plate 131 to move along the first direction and press against the molding teeth 121 through the connecting rod 132. All the molding teeth 121 are clamped between the hole wall of the first through hole 111 away from the second through hole 112 and the push plate 131, thereby restricting the movement of all the molding teeth 121. When the eccentric wheel 133 rotates from the locked position to the unlocked position, the connecting rod 132 can pull the push plate 131 to move toward the eccentric wheel 133, so that the push plate 131 can move away from the molding teeth 121, and the molding teeth 121 can move along the first direction.

[0044] Specifically, the eccentric wheel 133 is provided with a first elastic element (not shown in the figure). The first elastic element always has the tendency to drive the eccentric wheel 133 to rotate toward the locking position, so that the push plate 131 always maintains a pressing force to lock the push plate 131.

[0045] In the example, the first elastic element is a torsion spring.

[0046] Furthermore, a handle is provided on the side of the eccentric wheel 133 away from the push plate 131, with the handle extending out of the second through hole 112 from the outside of the connecting seat 11. The handle allows the eccentric wheel 133 to rotate against the elastic force of the first elastic element, thereby unlocking the taking-up teeth 121.

[0047] Specifically, such as Figure 1 As shown, the sealing device is provided with two connectors 2, which are respectively located on opposite sides of the clearance hole along the second direction, so that the two sealing plates 1 are subjected to force evenly, thereby improving the connection stability of the two sealing plates 1.

[0048] Of course, the number of connectors 2 is not limited to two; there can be two or more.

[0049] In one embodiment, such as Figure 7 As shown, the connector 2 includes a sleeve 21, a second elastic element 22, and two hooks 23. One end of each hook 23 is movably disposed inside the sleeve 21, and the other end is engaged with the connecting seat 11 of each of the two sealing plates 1. The second elastic element 22 is disposed inside the sleeve 21, and both ends of the second elastic element 22 are connected to the ends of the two hooks 23. The second elastic element 22 drives the two hooks 23 to have a relative movement tendency. The two hooks 23 can be engaged with the side walls of the connecting seat 11 of each of the two sealing plates 1, and the second elastic element 22 can ensure that the two sealing plates 1 always maintain a pressing force, which is beneficial to the stable splicing of the two sealing plates 1.

[0050] Furthermore, such as Figure 2 As shown, the connector 11 is provided with a slot 113, and the hook 23 is inserted into the slot 113. This design can prevent the hook 23 from slipping off the side wall of the connector 11, improve the connection stability of the connector 2, and thus improve the stability of the splicing of the two sealing plates 1.

[0051] In another embodiment, such as Figure 1 and Figure 8 As shown, the connector 2 includes a telescopic rod 24. One end of the telescopic rod 24 has a fixing hole, and a fastener (not shown in the figure) is movably installed in the fixing hole. The end of the telescopic rod 24 away from the fixing hole is rotatably connected to the connecting seat 11 by a rivet, and the other end can be connected to the connecting seat 11 of any sealing plate 1 by a fastener. Specifically, the end of the telescopic rod 24 away from the fixing hole has a first opening, and the end of the connecting seat 11 has a second opening. One end of the rivet passes through the first opening and the second opening to rivet the connecting seat 11 and the connector 2. The end of the connecting seat 11 away from the second opening has a threaded hole, and the fastener is a screw that can be connected to the threaded hole.

[0052] When the sealing plates 1 do not need to be spliced, the connector 2 can rotate to be parallel to the connecting seat 11 that is rotatably connected to it. By adjusting the length of the telescopic rod 24, the fastener can be connected to the threaded hole of the connecting seat 11. When two sealing plates 1 are spliced, the second opening of the connecting seat 11 of one sealing plate 1 is aligned with the threaded hole of the other sealing plate 1. The connector 2 is rotated to be perpendicular to the connecting seat 11 that is rotatably connected to it, and the length of the telescopic rod 24 is adjusted so that the fastener can be connected to the connecting seat 11 of the other sealing plate 1, thus splicing the two sealing plates 1. This design integrates the connector 2 and the sealing plate 1 into a whole. The connector 2 is not easy to fall off the sealing plate 1, making it convenient to carry and store, and also helps to improve the connection stability of the two sealing plates 1.

[0053] Specifically, the telescopic rod 24 includes a first rod and a second rod, which are connected by threads. This design allows the telescopic rod 24 to be kept at the adjusted length, preventing the telescopic rod 24 from extending or retracting and causing the sealing plate 1 to become unstable.
