Description

Technical Field

[0001] This invention belongs to the field of substation equipment technology, and in particular relates to a fully automatic intelligent rodent-blocking device for substation room doors. Background Technology

[0002] Rodent barriers are widely used in grain depots, gas stations, substations, chemical plants, and other similar establishments to effectively protect against rodents. In substations, rats can easily chew through cables, affecting equipment safety. Currently, substation rodent barriers are typically fixed by inserting a slot into the door frame, the size and height of which matches the barrier's dimensions. However, during routine work, such as moving heavy equipment or maintaining infrastructure, the barriers need to be removed. Sometimes, due to a lack of safety awareness among on-site staff, the barriers are removed haphazardly for ease of movement. This repeated removal and installation can damage the slots, making the barriers difficult to secure and compromising their effectiveness. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this invention is to provide a fully automatic intelligent rodent-blocking device for substation room doors, which effectively solves the problems of inconvenient operation and reduced rodent-blocking effect.

[0004] The technical solution to the technical problem is as follows: A door frame is included, with a first baffle rotatably connected to the front side of the door frame. A cavity is provided inside the first baffle, and a second baffle is slidably connected vertically within the cavity. A first guide rod and a second guide rod are fixed to the upper end of the second baffle, both sliding vertically within the first baffle. A first trapezoidal block is fixed to the upper end of the first guide rod above the first baffle, and a second trapezoidal block is fixed to the upper end of the second guide rod above the first baffle. The first and second trapezoidal blocks are symmetrical about the middle position of the first baffle. A double-acting cylinder is installed in the middle position of the first baffle, and the left side of the double-acting cylinder is slidably connected... There is a first telescopic rod, and a first roller is hinged to the other end of the first telescopic rod. The first roller contacts the inclined surface of the first trapezoidal block. The first telescopic rod controls the first trapezoidal block and the first guide rod to move downward as a whole through the first roller. A second telescopic rod is slidably connected to the right side of the bidirectional cylinder. The other end of the second telescopic rod is hinged to the second roller. The second roller contacts the inclined surface of the second trapezoidal block. The second telescopic rod controls the second trapezoidal block and the second guide rod to move downward as a whole through the second roller. Springs are sleeved on the first guide rod and the second guide rod and are located in the cavity. The upper end of the spring is fixed to the first baffle, and the lower end of the spring is fixed to the second baffle.

[0005] Preferably, a vertically oriented rotating shaft is rotatably connected to the left side of the door frame, and the rotating shaft is fixedly connected to the left side of the first baffle. The rotating shaft controls the first baffle to rotate in front of the door frame.

[0006] Preferably, a bracket located above and below the first baffle is fixed on the front side of the door frame, and the rotating shaft is rotatably connected to the bracket.

[0007] Preferably, a motor is installed on the door frame, and the motor is coaxially and fixedly connected to the upper end of the rotating shaft via a reducer.

[0008] Preferably, a first magnetic strip is fixed to the right end of the first baffle, and a second magnetic strip that attracts the first magnetic strip is fixed to the right end of the door frame.

[0009] The present invention has the following advantages over traditional equipment: 1) It has a clever structure, high degree of automation, and simple operation. It adopts a two-way cylinder with good linkage, so that the first guide rod and the second guide rod can drive the second baffle to move downward at the same time, which seals the gap between the first baffle and the ground. The combination of the first baffle and the second baffle completely seals the bottom of the substation room door, effectively preventing rats from entering its interior, and has a good rat-proof effect; 2) The rotating shaft drives the first baffle to rotate, and the rotation angle is large, which facilitates the normal opening or closing of the substation room door, with good flexibility and economic practicality.

[0012] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3Provided is a fully automatic intelligent rodent-blocking device for a substation room door, comprising a door frame 1, a first baffle 2 rotatably connected to the front of the door frame 1, a cavity 3 provided in the first baffle 2, a second baffle 4 slidably connected to the cavity 3, a first guide rod 5 and a second guide rod 6 fixed to the upper end of the second baffle 4, both the first guide rod 5 and the second guide rod 6 sliding up and down within the first baffle 2, a first trapezoidal block 7 fixed to the upper end of the first guide rod 5 above the first baffle 2, and a second trapezoidal block 8 fixed to the upper end of the second guide rod 6 above the first baffle 2, the first trapezoidal block 7 and the second trapezoidal block 8 being symmetrical about the middle position of the first baffle 2, a bidirectional cylinder 9 installed at the middle position of the first baffle 2, and a first telescopic cylinder slidably connected to the left side of the bidirectional cylinder 9. The first telescopic rod 10 has a first roller 11 hinged to the other end. The first roller 11 contacts the inclined surface of the first trapezoidal block 7. The first telescopic rod 10 controls the first trapezoidal block 7 and the first guide rod 5 to move downward as a whole via the first roller 11. The right side of the bidirectional cylinder 9 is slidably connected to the second telescopic rod 12. The other end of the second telescopic rod 12 is hinged to the second roller 13. The second roller 13 contacts the inclined surface of the second trapezoidal block 8. The second telescopic rod 12 controls the second trapezoidal block 8 and the second guide rod 6 to move downward as a whole via the second roller 13. The first guide rod 5 and the second guide rod 6 are both fitted with springs 14 located in the cavity 3. The upper end of the spring 14 is fixed on the first baffle 2, and the lower end of the spring 14 is fixed on the second baffle 4.

[0014] To facilitate the opening or closing of the first baffle 2, a vertical rotating shaft 15 is rotatably connected to the left side of the door frame 1. The rotating shaft 15 is fixedly connected to the left side of the first baffle 2, and the rotating shaft 15 controls the first baffle 2 to rotate in front of the door frame 1.

[0015] To ensure the stability of the rotation of the rotating shaft 15, a bracket 16 is fixed on the front side of the door frame 1, located above and below the first baffle 2, and the rotating shaft 15 is rotatably connected to the bracket 16.

[0016] A motor 17 is installed on the door frame 1, and the motor 17 is fixedly connected to the upper end of the rotating shaft 15 via a reducer.

[0017] To ensure the fit between the first baffle 2 and the door frame 1, a first magnetic strip 18 is fixed to the right end of the first baffle 2, and a second magnetic strip 19 that attracts the first magnetic strip 18 is fixed to the right end of the door frame 1.

[0018] In use, after the substation room door is closed, motor 17 is started. Motor 17 drives rotating shaft 15 to rotate via reducer. Rotating shaft 15 drives first baffle 2 to rotate. When first baffle 2 is in contact with door frame 1, first magnet strip 18 and second magnet strip 19 attract each other, thus ensuring the fit between first baffle 2 and door frame 1. Since there is a certain gap between first baffle 2 and the ground, bidirectional cylinder 9 is activated. Bidirectional cylinder 9 controls first telescopic rod 10 and second telescopic rod 12 to move outward simultaneously. First telescopic rod 10 controls first roller 11 to move to the left. First roller 11 presses the inclined surface of first trapezoidal block 7 to the left. First trapezoidal block 7 and second trapezoidal block 8 are both right-angled trapezoidal blocks. The first guide rod 5 moves downward within the first baffle 2. At the same time, the second telescopic rod 12 controls the second roller 13 to move to the right. The second roller 13 presses the inclined surface of the second trapezoidal block 8 to the right. The second trapezoidal block 8 drives the second guide rod 6 to move downward within the first baffle 2. Then, the first guide rod 5 and the second guide rod 6 simultaneously drive the second baffle 4 to move downward within the cavity 3. The spring 14 is in a stretched state. When the second baffle 4 is completely in contact with the ground, the bidirectional cylinder 9 is closed. At this time, the first baffle 2 and the second baffle 4 completely seal the door frame 1 at the bottom of the substation room door. The height of the first baffle 2 is about 40cm, which can play a good role in preventing rats from entering the substation room door. It is safe, reliable, and has a good sealing effect. When the substation room door needs to be opened, the bidirectional cylinder 9 is activated. The bidirectional cylinder 9 drives the first telescopic rod 10 and the second telescopic rod 12 to reset simultaneously. The first roller 11 moves away from the first trapezoidal block 7, and the second roller 13 moves away from the second trapezoidal block 8. Under the reset action of the spring 14, the second baffle 4 resets upward in the cavity 3. The second baffle 4 is located inside the cavity 3, ensuring the gap between the first baffle 2 and the ground, and avoiding interference between the first baffle 2 and the ground during rotation. Then, the reverse motor 17 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the first baffle 2 away from the door frame 1, and the first magnet strip 18 and the second magnet strip 19 disengage. The maximum rotation angle of the first baffle 2 is 180 degrees, which does not affect the normal use of the substation room door at all. The operation is simple and highly automated. The motor 17 and the bidirectional cylinder 9 are electrically connected to an external power supply via an external control switch. The control method of the electrical components is controlled by their matching peripheral controller. The control circuit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not improved. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0019] This embodiment does not impose any limitation on the shape, material, structure, etc. of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
