Description

Technical Field

[0001] The present invention relates to the technical field of optical cable cabinets, and more particularly to an outdoor cabinet with a top that can be unfolded to block rain. Background Art

[0002] The outdoor optical cable protection cabinet has high anti-vibration, anti-dust, waterproof and windproof properties, and can withstand various harsh outdoor environments to ensure the safe operation of optical cables, optical fiber splitters, switches and other equipment. This protection plays an important role in maintaining the stability and reliability of optical cable communication networks.

[0003] In the existing public documents, the patent with patent announcement number CN104317027A discloses an outdoor optical cable lightning protection cabinet, which is connected to the lightning protection compartment at the bottom of the equipment compartment; a lightning protection ground bar is arranged in the lightning protection compartment and is insulated from the outer shell of the lightning protection cabinet, and the lightning protection ground bar has at least one cable fixing part; the optical cable harness with a metal reinforcement core is separated into a metal reinforcement core and an optical cable core at the tail end, and the optical cable core extends into the equipment compartment from the opening at the top of the lightning protection compartment, and the metal reinforcement core is grounded through the cable fixing part. The lightning protection cabinet of this invention effectively realizes the grounding of the metal reinforcement core for lightning protection. However, the optical cable cabinet still has the following problems when in use.

[0004] When the optical cable cabinet is performing external protection on the optical cable, it is usually necessary to implement outdoor rainproof operation on the optical cable. During the rainproof process, the optical cable cabinet and the cabinet door need to be closed to prevent external rainwater from entering the optical cable cabinet and causing damage to the optical cable. During long-term use, the operator's misoperation may cause the cabinet door to not be completely closed or the sealing position to age. At the same time, there is a large amount of external rain, which will cause rainwater to enter the optical cable cabinet through the door. It is difficult to know the water ingress status in time, and it is difficult to make the outdoor cabinet automatically unfold in time to perform rainproof operation. It is very easy to cause rainwater to continue to flow back into the outdoor cabinet and cause damage to the optical cable. The external protection of the optical cable is poor, so an outdoor cabinet with a top that can be unfolded to block rain is required. Summary of the invention

The inner wall of the optical cable cabinet is fixedly connected to an optical cable fixing bar, and one side of the inner wall of the optical cable cabinet is fixedly connected to multiple optical cable fixing side bars.

[0008] When this technology is in use, the reduction motor drives the screw to rotate forward, the sleeve block drives the linkage frame to move upward, the position-shifting motor drives the linkage screw to move upward, and the two threaded sleeve blocks drive the two tilting bars to move upward synchronously. The support sleeve block moves the immersion sensor upward, and the two immersion sensors are shifted upward.

[0010] A guide column is installed on the inner wall of the concave block, and the two concave blocks are slidably connected to the outer wall of the guide column, and one end of the guide column is fixedly connected to a guide frame, and the guide frame is fixedly connected to the optical cable cabinet shell; a support shaft is fixedly connected to one side of the unfolding baffle and close to and at the top position, and a linkage block is provided on the outer wall of the support shaft, and the two support shafts are rotatably connected to the linkage block, and an arc-shaped rubber pad is installed on the top of the unfolding baffle, and the two unfolding baffles are bonded to the arc-shaped rubber pad; a lateral unfolding rainproof mechanism is installed on the inclined surface of one side of the unfolding baffle, the center point of the hinge shaft is higher than the center point of the connecting shaft, and the vertical cross-section shapes of the hinge shaft and the connecting shaft are both circular, the two concave blocks are slidably connected to the guide frame, and the outer wall of the concave block and the inner wall of the guide frame are both smooth surfaces.

[0011] When this technology is in use, the electric cylinder pushes the articulated block upward, the two connecting shafts respectively drive the bottom ends of the two sleeve shafts to move upward synchronously, the top of the sleeve shaft drives the articulated shaft to move left, and the other articulated shaft moves right, and the concave sleeve block slides left along the outer wall of the guide column.

[0012] The bottom end of the expansion baffle extends to the left along the top of the optical cable cabinet, and the other expansion baffle extends to the right along the top of the optical cable cabinet, so that the two expansion baffles can extend at the top of the optical cable cabinet, thereby shielding the gap between the optical cable cabinet and the cover door from rain. When the left side of the concave sleeve is attached to the right side of the inner wall of the guide frame, the electric cylinder is closed by the controller.

[0013] Preferably, a support frame is fixedly installed on one inclined surface of the side of the unfolding baffle of the lateral unfolding rainproof mechanism; a bidirectional screw is rotatably connected to the inner wall of the support frame, and a transmission motor is fixedly connected to one side of the inner wall of the support frame, and the transmission motor is used to drive the bidirectional screw to rotate, and the two threads on the outer wall of the bidirectional screw are opposite and symmetrical; the outer wall of the bidirectional screw is threadedly connected to two sleeve sliders, one side of each sleeve slider is fixedly connected to a side display panel, and the top of the side display panel is fixedly connected to an inclined plate; a slide bar is fixedly connected to one side of the side display panel and close to the inclined plate, and the inclined plate and the slide bar are both slidably connected to the unfolding baffle.

The reduction motor drives the screw rod to rotate forward, and the screw rod drives the sleeve block to move upward under the action of the thread transmission force, and the support sleeve block causes the immersion sensor to move upward, and the two immersion sensors move upward and shift. The controller starts the displacement motor to drive the linkage screw rod to rotate forward, and the distance between the two threaded sleeve blocks becomes smaller, and the two immersion sensors can approach each other for sensing. At the same time, the linkage screw rod is driven by the displacement motor to reverse, and the distance between the two immersion sensors becomes larger, and the two immersion sensors can shift over a large area, thereby performing a large-area detection of the leakage position inside the sealing gasket strip, and being able to know the water ingress status in time, and making the expansion baffle on the top of the optical cable cabinet shell automatically expand in time, thereby performing rain protection between the optical cable cabinet shell and the cover door, preventing rainwater from continuously flowing back into the optical cable cabinet shell, thereby preventing damage to the optical cable inside the optical cable cabinet shell, and achieving better external protection of the optical cable.

[0016] 2. The present invention adopts a linkage expansion rainproof mechanism, the electric cylinder pushes the hinge block to move upward, the hinge block drives the two connecting shafts to move upward, the top of the sleeve shaft drives the hinge shaft to move left, the hinge shaft, and the other hinge shaft to move right, the concave sleeve block drives the sleeve frame to move left, the sleeve frame drives the rotating shaft to move left, the two expansion baffles drive the arc rubber pads to move downward, the bottom end of the expansion baffle extends to the left along the top of the optical cable cabinet shell, and at the same time, the other expansion baffle extends to the right along the top of the optical cable cabinet shell. The two expansion baffles can be quickly expanded at the top of the optical cable cabinet shell, so as to timely protect the leaking position between the optical cable cabinet shell and the cover door from rain, thereby preventing the optical cable inside the optical cable cabinet shell from being soaked and damaged by rainwater, and the external protection effect of the optical cable is better.

[0017] 3. The present invention utilizes a laterally unfolded rainproof mechanism. The controller starts the transmission motor, which drives the bidirectional screw to rotate. The bidirectional screw drives the two sleeved sliders to move away from each other under the action of the thread transmission force. The distance between the two sleeved sliders becomes larger, and the side expansion plate drives the inclined plate to move right. The side expansion plate also drives the slide bar to move right at the same time. The two side expansion plates move and expand to both sides respectively, which can quickly protect the gap between the optical cable cabinet shell and the cover door from rain. The lateral rainproof protection area is wider, which prevents the optical cable inside the optical cable cabinet shell from being damaged by water immersion, and makes the external protection of the optical cable better.

[0018] According to the mutual influence of the above multiple functions, firstly, the two immersion sensors can be displaced over a large area, and the water ingress condition can be known in time. Secondly, the two expansion baffles can be quickly expanded on the top of the optical cable cabinet shell, and finally the two side expansion panels move and expand to both sides. In summary, the water ingress problem can be known in time, so that the expansion baffles on the top of the optical cable cabinet shell can be automatically expanded in time, thereby providing rain protection between the optical cable cabinet shell and the cover door, preventing rainwater from continuously flowing back into the optical cable cabinet shell, thereby preventing damage to the optical cable inside the optical cable cabinet shell, and providing better protection for the outside of the optical cable.

The two sleeve sliders 36 are both slidably connected to the support frame 33, and the two threads on the outer wall of the bidirectional screw 34 are opposite and symmetrical.

[0037] The operating principle of the outdoor cabinet with the top unfolded to block rain of the present invention is as follows: Step 1: When installing and fixing the optical cable, first open two holes at the bottom of the inner wall of the optical cable cabinet 1, one for the inlet hole and the other for the outlet hole, so that the optical cable can enter the optical cable cabinet 1 from the inlet hole, and a part of the optical cable is placed inside the optical cable fixing fence 16 for fixing. At the same time, the other part of the optical cable is placed inside the multiple optical cable fixing side fences 17 for fixing, so that the optical cable cabinet 1 can protect the outside of the optical cable. At the same time, turn the cover door 2, the cover door 2 drives the sealing gasket strip 3 to move and squeeze at the opening position of the optical cable cabinet 1, and at the same time, the cover door 2 drives the hole frame 4 to squeeze inside the optical cable cabinet 1, so that the cover pressing operation of the optical cable cabinet 1 is realized, thereby performing an outdoor sealing operation on the optical cable cabinet 1, which can prevent external rainwater from entering the interior of the optical cable cabinet 1.

[0038] Step 2, during the displacement detection protection, when it rains outside, rainwater flows down along the gap between the optical cable cabinet shell 1 and the cover door 2. Since the sealing strip 3 and the optical cable cabinet shell 1 are sealed in a protective operation, it can play a certain sealing role. However, the optical cable cabinet shell 1 and the cover door 2 are not closed tightly, or the sealing strip 3 is aged, so that a leaking gap is generated between the optical cable cabinet shell 1 and the cover door 2, so that the external rainwater can flow to the hole frame 4 through the sealing strip 3, and drip along the hole frame 4. At the same time, the controller 19 starts the reduction motor 7, the reduction motor 7 drives the screw 6 to rotate forward, the screw 6 drives the socket block 8 to move up under the action of the thread transmission force, the socket block 8 drives the linkage frame 9 to move up, the linkage frame 9 drives the displacement motor 11 to move up, and the displacement motor 11 causes the linkage screw 10 to move up, the linkage screw 10 drives the two threaded sleeves 12 to move up synchronously, and the two threaded sleeves 12 respectively drive the two inclined bars 13 to move up synchronously. At the same time, the two inclined bars 13 drive the two supporting blocks 14 to move upward synchronously, and the supporting blocks 14 cause the immersion sensors 15 to move upward, and the two immersion sensors 15 move upward and change position.

[0039] At the same time, the controller 19 starts the position changing motor 11 to drive the linkage screw 10 to rotate forward. The linkage screw 10 drives the two threaded sleeves 12 to approach each other under the action of the thread transmission force, and the distance between the two threaded sleeves 12 becomes smaller, so that the threaded sleeve 12 moves to the left, and the other threaded sleeve 12 moves to the right. The threaded sleeve 12 drives the tilting bar 13 to move left, and the tilting bar 13 drives the supporting sleeve 14 to move left. The supporting sleeve 14 causes the immersion sensor 15 to move left, and at the same time, the other immersion sensor 15 moves right.

[0040] The two immersion sensors 15 can approach each other. Then, the linkage screw 10 is driven to reverse by the displacement motor 11, so that the linkage screw 10 drives the two threaded sleeves 12 to move away from each other under the action of the thread transmission force, and the distance between the two threaded sleeves 12 increases. The threaded sleeve 12 drives the tilting bar 13 to move right, and the tilting bar 13 drives the support sleeve 14 to move right. The support sleeve 14 makes the immersion sensor 15 move right, and the distance between the two immersion sensors 15 increases. The two immersion sensors 15 can be reciprocated horizontally, and the two immersion sensors 15 can also move upward. The two immersion sensors 15 can detect the internal leakage position of the sealing gasket strip 3 over a large area. When the immersion sensor 15 senses external rain, the electric cylinder 18 is started through the controller 19.

[0041] Step three, when the rain shield is deployed in linkage, the electric cylinder 18 pushes the hinge block 20 to move upward, the hinge block 20 drives the two connecting shafts 21 to move upward, the two connecting shafts 21 respectively drive the bottom ends of the two sleeve shafts 22 to move upward synchronously, the top of the sleeve shaft 22 drives the hinge shaft 23 to move left, and the other hinge shaft 23 moves right, the hinge shaft 23 drives the concave sleeve block 24 to move left, the concave sleeve block 24 slides to the left along the outer wall of the guide column 28, and the concave sleeve block 24 slides to the left along the inner wall of the guide frame 29. At the same time, the concave sleeve block 24 drives the sleeve frame 25 to move left, the sleeve frame 25 drives the rotating shaft 26 to move left, and at the same time the rotating shaft 26 drives the bottom of the expansion baffle 27 to move left, and the expansion baffle 27 drives the support shaft 30 to move downward, the support shaft 30 rotates inside the linkage sleeve block 31, and at the same time the support shaft 30 drives the linkage sleeve block 31 to move downward, and the two expansion baffles 27 drive the arc rubber pad 32 to move downward. Since the arc rubber pad 32 is made of rubber, the arc rubber pad 32 can achieve deformation and downward movement.

[0042] The bottom end of the unfolded baffle 27 extends to the left along the top of the optical cable cabinet 1, and the other unfolded baffle 27 extends to the right along the top of the optical cable cabinet 1, so that the two unfolded baffles 27 can extend at the top of the optical cable cabinet 1, thereby shielding the gap between the optical cable cabinet 1 and the cover door 2 from rain. When the left side of the concave sleeve block 24 is attached to the right side of the inner wall of the guide frame 29, the electric cylinder 18 is closed by the controller 19.

[0043] Step 4: When the rain shield is deployed sideways, the controller 19 starts the transmission motor 35 at the same time, and the transmission motor 35 drives the bidirectional screw 34 to rotate. The bidirectional screw 34 rotates inside the support frame 33. At the same time, the bidirectional screw 34 drives the two sleeve sliders 36 to move away from each other under the action of the thread transmission force, and the distance between the two sleeve sliders 36 becomes larger. At the same time, the sleeve slider 36 drives the side display panel 37 to move right, and the other sleeve slider 36 drives the other side display panel 37 to move left, and the side display panel 37 drives the inclined plate 38 to move right, and the side display panel 37 will also drive the slide bar 39 to move right, and the two side display panels 37 move and expand to both sides respectively, so that the side display panel 37 can expand the right side of the unfolded baffle 27 to block rain, and the other side display panel 37 can expand the left side of the unfolded baffle 27 to block rain, so that the two side display panels 37 and the unfolded baffle 27 can quickly protect the gap at the connection between the optical cable cabinet shell 1 and the cover door 2 from rain, so as to prevent the optical cable inside the optical cable cabinet shell 1 from being soaked in water and damaged, thereby realizing external protection operation for the optical cable.
