Description

Technical Field

[0001] The utility model relates to the technical field of electrical safety auxiliary devices, in particular to a rat-proof device for temporary cable holes. Background Technique

[0002] In the petrochemical industry, which highly depends on power supply, the demand for temporary power use is frequent and crucial, running through all aspects such as daily production, maintenance, overhaul and special operations.

[0003] In the distribution room of petrochemical enterprises, in order to conveniently guide the cables through the wall to the outside, cable holes are usually pre-designed and drilled. When these holes are not in use, in order to maintain the cleanliness and safety of the distribution room, they need to be effectively closed. The traditional method is to install a circular baffle outside the hole, and a rotating shaft is arranged between the circular baffle and the wall, so that the baffle can rotate around the hole to achieve the functions of blocking and opening. Although this design is simple and direct, some problems have gradually emerged in the long-term use process.

[0004] First of all, due to the frequent rotation and wear at the rotating shaft, combined with possible material aging or improper installation, the rotating shaft part of the baffle is very easy to loosen, resulting in the baffle being unable to stably stay in the predetermined position. This not only affects the sealing effect of the cable hole, but also may cause unnecessary extrusion of the passing cables due to the offset of the baffle position, increasing the risk of cable damage.

[0005] Secondly, the edge of the rotating baffle may come into contact with the cable during rotation. If the edge of the baffle is untreated or has sharp corners, it is very easy to scratch the outer skin of the cable, thereby affecting the insulation performance and service life of the cable. In addition, due to the relatively thin design around the baffle, when the staff manually operates the rotating baffle, if they are not careful, they may be scratched by its sharp edge, increasing the safety hazard during the operation process. Content of the Utility Model

[0006] In order to solve the deficiencies of the existing technology, the utility model provides a rat-proof device for temporary cable holes.

[0007] To achieve the above purpose, the technical solution of the utility model is: a rat-proof device for temporary cable holes, including a fixed seat and a baffle storage seat connected to one side of the fixed seat. The fixed seat is stacked with a first baffle and several second baffles. Both the first baffle and the second baffle are in a fan-shaped structure. A first rotating shaft is arranged at the fan-shaped edge of the first baffle, and the first rotating shaft rotatably connects the first baffle in the fixed seat. A second rotating shaft is arranged at the center of the circle of the first baffle and the second baffle. A cable pipeline is connected behind the fixed seat, and a pipeline fixing ring is arranged on the cable pipeline.

[0008] Further, a fixing seat clamping groove is arranged in the fixing seat, and the edges of the first baffle and the second baffle are arranged in the fixing seat clamping groove.

[0009] Further, a baffle moving rod penetrates through the edges of the first baffle and the second baffle, and a first fixing hole one and a second fixing hole for fixing the baffle moving rod are arranged in the fixing seat.

[0010] Further, a moving rod guide rail is arranged on the baffle storage seat, and the moving rod guide rail is the moving track of the baffle moving rod in the baffle storage seat.

[0011] Further, the baffle moving rod is a screw rod, and internal threads matching the baffle moving rod are arranged in the first fixing hole one and the second fixing hole of the moving rod.

[0012] Further, the first baffle includes a first sector baffle, a first limiting plate is arranged on one side of the first sector baffle, and a second limiting plate is arranged on the other side of the first sector baffle.

[0013] Further, the total thickness of the first limiting plate and the first sector baffle is the same as the thickness of the fixing seat clamping groove.

[0014] Further, the second baffle includes a second sector baffle, a third limiting plate is arranged on one side of the second sector baffle, a fourth limiting plate is arranged on the other side of the second sector baffle, and the third limiting plate and the fourth limiting plate are respectively arranged on the front and back surfaces of the second sector baffle.

[0015] Further, a first rotating plate is arranged at the center of the circle of the first sector baffle, and a second rotating plate is arranged at the center of the circle of the second sector baffle.

[0016] Further, an external thread is arranged on the outer part of the cable pipeline, and an internal thread matching the cable pipeline is arranged in the pipeline fixing ring.

[0017] The beneficial effects achieved by the utility model are as follows:

[0018] 1. When the cable needs to pass through in the utility model, the first baffle and several second baffles are fixed together through the baffle moving rod. After being fixed, the first baffle and several second baffles rotate around the first rotating shaft and enter the baffle storage seat along the moving rod guide rail, and the cable through hole is completely exposed outside, which is convenient for the staff to send the cable out of the power distribution room. The first baffle and several second baffles stored in the baffle storage seat do not contact the cable, avoiding the risk of cable damage, and the staff can complete the opening and closing of the hole only by using the baffle moving rod, reducing the potential safety hazard in the operation process.

[0019] 2. The utility model drives several second baffles to move in a circular motion within the fixing seat clamping grooves of the fixing seat through the baffle moving rod. Finally, the baffle moving rod fixes the second baffle that rotates and moves first in the second fixing hole of the moving rod. The first baffle and the second baffle cooperate with each other to form a circle, blocking the cable through-hole within the fixing seat, preventing small animals from entering the power distribution room through the cable through-hole, and avoiding accidents such as short circuits and tripping power outages in the circuit.

[0020] 3. On the left and right sides of the first sector baffle in the utility model, a first limiting plate and a second limiting plate are respectively arranged. On the left and right sides of the second sector baffle, a third limiting plate and a fourth limiting plate are respectively arranged. The second limiting plate and the third limiting plate cooperate with each other to prevent the second baffle that rotates and moves last from separating from the first baffle. The third limiting plate and the fourth limiting plate within adjacent two second baffles cooperate with each other, enabling adjacent two second baffles to restrict each other during rotation and avoiding separation between adjacent two second baffles. The total thickness of the first limiting plate and the first sector baffle is the same as the thickness of the fixing seat clamping groove. The first limiting plate contacts the fourth limiting plate in the second baffle that rotates and moves first, and can completely block the cable through-hole.

[0021] 4. The moving rod guide rail in the utility model is of an arc structure. After the baffle moving rod drives the first baffle and several second baffles into the baffle storage seat, the first baffle and several second baffles, due to their own gravity, stably set the baffle moving rod within the moving rod guide rail. Without setting other structures, it prevents the baffle moving rod from separating from the moving rod guide rail.

[0022] 5. The utility model is stably and reliably installed. The rear end of the cable pipeline is threadedly connected with a pipeline positioning ring. The pipeline positioning ring and the fixing seat cooperate with each other to fix the utility model on the wall of the power distribution room. The position of the pipeline positioning ring on the cable pipeline can be adjusted arbitrarily, enabling the utility model to be applicable to walls of different thicknesses in the power distribution room.

The first baffle 3 and several second baffles 4 are arranged in contact with each other front and back. The first baffle 3 and several second baffles 4 have a common center of the circle. A second rotating shaft 6 is arranged at the center of the circle. The second rotating shaft 6 sequentially penetrates through the first baffle 3 and several second baffles 4 to connect the first baffle 3 and several second baffles 4 together. The first baffle 3 and several second baffles 4 can rotate around the second rotating shaft 6 in the fixed seat 1. A first rotating shaft 5 is arranged between the first baffle 3 and the fixed seat 1. The first rotating shaft 5 connects the first baffle 3 and the fixed seat 1 together. A baffle storage slot is arranged in the baffle storage seat 2. The baffle storage slot can accommodate all the first baffles 3 and several second baffles 4. When the cable through-hole needs to be exposed, the first baffle 3 and several second baffles 4 can enter the baffle storage slot in the baffle storage seat 2. The first baffles 3 and several second baffles 4 stored in the baffle storage seat 2 do not contact the cable, avoiding the risk of cable damage. A cable duct 8 is fixedly connected to the rear of the fixed seat 1. The cross-sectional area of the cable duct 8 is smaller than the cross-sectional area of the fixed seat 1. External threads are arranged on the outer wall of the cable duct 8. A pipe fixing ring 9 is threadedly connected to the outside of the cable duct 8. Internal threads matching the external threads of the cable duct 8 are arranged in the pipe fixing ring 9. The pipe positioning ring and the fixed seat 1 cooperate with each other to fix the present utility model on the wall of the power distribution room. The position of the pipe positioning ring on the cable duct 8 can be adjusted arbitrarily, so that the present utility model can be applicable to walls of different thicknesses in the power distribution room.

[0033] A fixing base 1 is provided with a fixing base clamping groove 104. The fixing base clamping groove 104 is of an annular structure. A first baffle 3 and a plurality of second baffles 4 are arranged in the fixing base clamping groove 104.
