Description

Technical Field

[0001] This invention relates to the field of outdoor power distribution cabinet technology, and in particular to an outdoor safety power distribution cabinet. Background Technology

[0002] A distribution cabinet is a power terminal device used to distribute power to nearby loads and provide protection, monitoring and control for electrical loads. Outdoor distribution cabinets generally refer to distribution cabinets that are installed independently outdoors or used in the field. When outdoor distribution cabinets are installed and used in the field, they are far away from the workstation and cannot be frequently inspected manually. Therefore, they need to have a good ability to deal with unexpected situations or failures, and thus have high safety requirements.

[0003] Most existing outdoor distribution cabinets lack protective mechanisms against wild animals, failing to effectively reduce impact damage from large wild animals. This makes the cabinets vulnerable to damage by wild animals. Although some distribution cabinets are equipped with protective mechanisms against wild animals, the drive structure of these mechanisms is not designed reasonably. They mostly rely on manual lifting and moving to achieve separation and loosening of the cabinet. Since the protective mechanisms inevitably contain some parts that prevent wild animals from approaching and cause them pain or comfort (such as needles), hands are easily pricked. Furthermore, avoiding pricks increases the need for hand avoidance, further complicating the loosening and loosening of the protective mechanisms. Summary of the Invention

[0004] In view of this, the present invention provides an outdoor safety distribution cabinet to solve the problem of unreasonable design of the drive structure of the protective mechanism. Most of them directly use the hands to lift and move to achieve the separation and loosening of the distribution cabinet. Since the protective mechanism inevitably has some parts that can prevent wild animals from approaching and make wild animals feel pain or comfort (such as needles), this makes it easy for the hands to be pricked. Furthermore, the avoidance of pricks will increase the avoidance action of the hands, which will increase the difficulty of loosening and loosening the protective mechanism.

[0005] This invention provides an outdoor safety distribution cabinet, specifically comprising: a cabinet body, the cabinet body having a rectangular structure, and a cable tray located in the middle of the base plate of the cabinet body; a row of safety guardrails slidingly mounted on the cabinet body from top to bottom, with the cabinet door at the front of the cabinet body in a closed state contacting and blocking the front side bars of the row of safety guardrails; a row of spikes welded to the four side bars of the safety guardrails, and two rows of short steel wire ropes connecting the middle sections of the left and right side bars of the row of safety guardrails; the cabinet body... Four vertical support rods are symmetrically welded to the top of the structure, and a rectangular beam frame is horizontally welded to the top of each support rod. Two short steel wire ropes are symmetrically connected between the left and right side rods of the top safety protection frame and the left and right side rods of the beam frame. Two guide wheels are symmetrically and rotatably installed at the rear ends of the left and right side rods of the beam frame. Two hand-cranked turntables are symmetrically and rotatably installed at the bottom rear sides of the left and right side walls of the distribution cabinet body. Two lifting steel wire ropes are threaded between the two hand-cranked turntables, the two guide wheels, and the left and right side rods of the bottom safety protection frame. The reverse rotation is used to retract and extend the two lifting wire ropes. The two hand-cranked turntables are connected by a drive shaft and two driven gears, allowing them to rotate synchronously. Through the two lifting wire ropes, the two hand-cranked turntables can rotate in both directions, pulling and driving the bottommost safety guard frame to slide up and down. When the bottommost safety guard frame slides upwards, a row of safety guard frames sequentially abuts against and stacks together, rising and sliding onto the four vertical support rods. This controls the row of safety guard frames to disengage from the distribution cabinet body and release the cabinet door, enabling the cabinet door to be opened. When the bottom safety protection frame slides down, a row of safety protection frames can slide down and fit onto the distribution cabinet body by their own gravity; a horizontally arranged drive shaft is rotatably installed at the bottom of the rear side wall of the distribution cabinet body, and two driven gears are symmetrically fitted at the left and right ends of the drive shaft; two rings of toothed plates are provided on the outer circumference of the limiting discs on the two hand cranks near the distribution cabinet body, and the two rings of toothed plates mesh with the two driven gears; a row of safety protection frames slides up and stacks on four vertical support rods.

[0006] Furthermore, on the left side wall of the power distribution cabinet body, two horizontal positioning shafts are welded at an interval between adjacent positions near the front of the hand-cranked turntable. An L-shaped plug is slidably installed on the two horizontal positioning shafts by spring pushing.

[0007] Furthermore, the L-shaped insert has two symmetrical inserts at its head end, which are engaged with a ring of teeth on the left hand crank.

[0008] Furthermore, the wire-threading groove has a rectangular structure, and two guide members are symmetrically inserted and welded on the front and rear sides of the wire-threading groove. The guide members have a cylindrical structure with strip-shaped notches.

[0009] Furthermore, two mounting plates are symmetrically fixed to the bottom of the left and right side walls of the power distribution cabinet body by screws, and both mounting plates are rectangular strip structures.

[0010] Furthermore, two sets of swing arms arranged in a figure-eight pattern are symmetrically mounted on the two mounting plates, one in front of the other, and each set of swing arms includes two parallel swing arms.

[0011] Furthermore, the bottom left and right sides of the power distribution cabinet body are symmetrically equipped with two ground contact plates, which are long strip-shaped structures.

[0012] Furthermore, a longitudinally arranged double-threaded shaft is rotatably installed at the top of each of the two ground contact plates, and two threaded blocks are symmetrically screwed onto the two double-threaded shafts.

[0013] Furthermore, the four threaded blocks are all square-shaped structures, and the tail ends of the four sets of rocker arms are rotatably connected to the four threaded blocks.

[0014] The beneficial effects are:

[0015] 1. In this invention, a row of safety protection frames is evenly inserted and covers the four sides of the distribution cabinet body. When wild animals come into contact with the distribution cabinet body, they will first touch the barbs around the safety protection frames. The barbs will prick the wild animals, causing them pain and discomfort, and causing them to move away from the distribution cabinet body. Compared with existing technologies that lack protective mechanisms against wild animals, this can effectively reduce the impact damage to the cabinet body caused by large wild animals and reduce the probability of the distribution cabinet body being damaged by wild animals. Under normal circumstances, the row of safety protection frames is positioned around the four sides of the distribution cabinet body by being suspended by two rows of short steel wire ropes on the left and right.

[0016] 2. In this invention, a row of safety protection frames suspended on the main body of the distribution cabinet can limit the cabinet door to a closed state, serving as a locking and positioning component for the cabinet door. This eliminates the trouble of configuring a locking and positioning component for the cabinet door and implementing the switching on and off of the additional locking and positioning component, making operation convenient and time-saving.

[0017] 3. This invention can control the insertion and release of a row of safety guard frames and the distribution cabinet body by rotating and releasing the lifting wire ropes at two hand-cranked turntables. This avoids direct contact between the hands and the spikes and safety guard frames. Compared with the existing technology that directly uses the hand lifting mechanism to achieve separation and assembly from the distribution cabinet, it can prevent the hands from being pricked during operation and also eliminates the need for hand avoidance actions to avoid pricks. The separation and assembly operation of the safety guard frames and the distribution cabinet is safer, simpler and more efficient.

[0018] 4. In this invention, the guide component has a smooth surface and arc guiding characteristics. Compared with the side of the cable tray that has not been passivated, it can avoid causing damage to the cable by pressing against it. It can also effectively reduce the frictional resistance between the cable and the side of the cable tray when the cable is being threaded, making the cable threading and installation time-saving and labor-saving.

[0019] 5. In this invention, four sets of rocker arms, four threaded blocks, and two mounting plates are connected together to form four sets of crank-slider mechanisms. Through these four mechanisms, the four threaded blocks can be moved synchronously forward and backward to drive the two mounting plates and the main body of the distribution cabinet to move up and down. The four sets of crank-slider mechanisms are used as the base support of the main body of the distribution cabinet. They are directly integrated and installed at the bottom of the main body of the distribution cabinet and can be moved together with the main body of the distribution cabinet. Compared with the existing technology of installing the base support separately from the main body of the distribution cabinet, it can save the trouble of additional matching and moving of the base support.

[0033] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0034] Please refer to Figures 1 to 8 As shown:

[0035] Example 1:

[0036] This invention provides an outdoor safety distribution cabinet, including a cabinet body 1. The cabinet body 1 has a rectangular structure, and a cable tray is provided in the middle of the bottom plate of the cabinet body 1. A row of safety protective frames 3 is slidably mounted on the cabinet body 1 from top to bottom. When the cabinet door at the front of the cabinet body 1 is in a closed state, it abuts against the front side rod of the row of safety protective frames 3. The row of safety protective frames 3 suspended on the cabinet body 1 can limit the cabinet door to a closed state, which can be used as a locking and positioning component for the cabinet door. This eliminates the trouble of configuring a locking and positioning component for the cabinet door and opening and closing the additional locking and positioning component, making operation convenient and time-saving. A row of spikes 301 are welded to the side rods of the four sides of the safety protective frames 3. The row of safety protective frames 3 is evenly inserted and covers the four sides of the cabinet body 1. When wild animals come into contact with the distribution cabinet, When the main body 1 is activated, it will first come into contact with the spikes 301 around the perimeter of a row of safety protection frames 3. The spikes 301 will prick wild animals, causing them pain and discomfort, and causing them to move away from the main body 1 of the distribution cabinet. This can effectively reduce the impact damage to the cabinet by large wild animals and reduce the probability of the main body 1 of the distribution cabinet being damaged by wild animals. Under normal circumstances, the row of safety protection frames 3 is suspended and positioned around the perimeter of the main body 1 by two rows of short steel wire ropes 6 on the left and right sides. The middle sections of the left and right side rods of the row of safety protection frames 3 are connected by two rows of short steel wire ropes 6. The top of the main body 1 of the distribution cabinet has four vertical support rods welded symmetrically on the left and right sides. The top of the four vertical support rods is horizontally welded with a rectangular beam frame 4. The left and right side rods of the top safety protection frames 3 and the left and right side rods of the beam frame 4 are symmetrically connected by two short steel wire ropes 6. The rear ends of the left and right side rods of the beam frame 4 are symmetrically rotated and installed with two guide wheels 401.Two hand-cranked turntables 104 are symmetrically and rotatably installed on the bottom rear side of the left and right side walls of the distribution cabinet body 1. Two lifting steel wire ropes 5 are threaded between the two hand-cranked turntables 104, two guide wheels 401, and the left and right side rods of the bottom safety guard frame 3. The two hand-cranked turntables 104 rotate in both directions to raise and lower the two lifting steel wire ropes 5. The two hand-cranked turntables 104 are connected together by a transmission shaft 105 and two driven gears on it, allowing them to be driven to rotate synchronously. The lifting wire rope 5 and two hand-cranked turntables 104 can rotate in both directions to drive the bottom safety guard frame 3 to slide up and down. When the bottom safety guard frame 3 slides upward, a row of safety guard frames 3 can sequentially abut against each other and stack together, rising and sliding onto the four vertical support rods. This controls the row of safety guard frames 3 to disengage from the distribution cabinet body 1 and release the cabinet door, enabling the cabinet door to be opened. Furthermore, when the bottom safety guard frame 3 slides downward, the row of safety guard frames 3, through their own weight... The force allows the material to slide downwards and fit over the main body 1 of the distribution cabinet. Furthermore, this invention uses two hand-cranked turntables 104 to rotate and retract the two lifting wire ropes 5, controlling the insertion and disengagement of a row of safety guard frames 3 from the main body 1 of the distribution cabinet. This avoids direct contact between the hands and the spikes 301 and the safety guard frames 3. Compared to existing technologies that directly use hand-lifting mechanisms to achieve disengagement and assembly from the distribution cabinet, this prevents hand injuries during operation and eliminates the need for manual intervention. The increased hand avoidance movements due to puncture wounds make the disengagement and assembly operations of the safety protection frame 3 and the distribution cabinet safer, simpler, and more efficient. A horizontally arranged drive shaft 105 is rotatably mounted at the bottom of the rear side wall of the distribution cabinet body 1. Two driven gears are symmetrically fitted at both ends of the drive shaft 105. Two rings of teeth are arranged on the outer circumference of the limiting discs on the two hand-cranked turntables 104 near the distribution cabinet body 1, and these two rings of teeth mesh with the two driven gears for transmission.

[0037] Among them, on the left side wall of the power distribution cabinet body 1, near the front adjacent position of the hand-cranked turntable 104, two horizontal positioning shafts 106 are welded at an interval. An L-shaped plug rod 107 is slidably installed on the two horizontal positioning shafts 106 by spring pushing.

[0038] The L-shaped plug rod 107 has two symmetrical inserts at its head end. The two inserts are engaged with a ring of teeth on the left hand crank turntable 104. Through the two inserts, the L-shaped plug rod 107 can be inserted into and positioned on the left and right hand crank turntables 104, so that the row of safety protection frames 3 is kept in the use state of sliding upward in the empty space of the power distribution cabinet body 1.

[0039] The cable tray has a rectangular structure, and two guide members 103 are symmetrically welded to the front and rear sides of the cable tray. The guide members 103 have a cylindrical structure with strip-shaped notches. The surface of the guide members 103 is smooth and has arc guiding characteristics. Compared with the side of the cable tray that has not been passivated, it can avoid damage to the cable by pressing against it, and can effectively reduce the frictional resistance between the cable and the side of the cable tray when the cable is pulled through, so that the cable pulling and installation is time-saving and labor-saving.

[0040] Among them, two mounting plates 101 are symmetrically fixed at the bottom of the left and right side walls of the power distribution cabinet body 1 by screws, and both mounting plates 101 are rectangular strip structures.

[0041] Example 2:

[0042] This invention provides an outdoor safety distribution cabinet, which also includes two sets of swing arms 102 arranged in a figure-eight pattern, symmetrically and rotatably mounted on two mounting plates 101. Each set of swing arms 102 includes two parallel swing arms 102. The four sets of swing arms 102, four threaded blocks 202, and the two mounting plates 101 are connected to form four sets of crank-slider mechanisms. Through these four mechanisms, the four threaded blocks 202 can be moved synchronously back and forth to drive the two mounting plates 101 and the distribution cabinet body 1 to move up and down. The four sets of crank-slider mechanisms are used as base supports for the distribution cabinet body 1. They are directly integrated and installed at the bottom of the distribution cabinet body 1 and can be moved together with the distribution cabinet body 1. Compared with the prior art of installing the base support separately from the distribution cabinet body 1, it can save the trouble of additional matching and moving of the base support.

[0043] The power distribution cabinet body 1 has two ground contact plates 2 symmetrically installed on the left and right sides of its bottom, and the two ground contact plates 2 are long strip-shaped structures.

[0044] Among them, a longitudinally arranged double-threaded shaft 201 is rotatably installed at the top of each of the two ground contact plates 2, and two threaded blocks 202 are symmetrically screwed onto the two double-threaded shafts 201.

[0045] Among them, the four threaded blocks 202 are all square strip structures, and the tail ends of the four sets of rocker arms 102 are rotatably connected to the four threaded blocks 202.

[0046] The specific usage and function of this embodiment: Under normal conditions, a row of safety protection frames 3 is suspended and positioned around the perimeter of the power distribution cabinet body 1 by two rows of short steel wire ropes 6 on the left and right. The row of safety protection frames 3 is evenly inserted and covers the perimeter of the power distribution cabinet body 1. When wild animals come into contact with the power distribution cabinet body 1, they will first come into contact with the barbs 301 around the perimeter of the row of safety protection frames 3. The barbs 301 will prick the wild animals, causing them pain and discomfort and making them stay away from the power distribution cabinet body 1, thus reducing the probability of the power distribution cabinet body 1 being damaged by wild animals. The row of safety protection frames 3 suspended and fitted on the power distribution cabinet body 1 can block and limit the cabinet door to a closed state, and act as a locking and positioning component for the cabinet door.

[0047] Two hand-cranked turntables 104 are connected by a drive shaft 105 and two driven gears thereon, and can be driven to rotate synchronously. Through two lifting steel wire ropes 5, the two hand-cranked turntables 104 can rotate in both directions, pulling and driving the bottommost safety guard frame 3 to slide up and down. When the bottommost safety guard frame 3 slides upward, a row of safety guard frames 3 can sequentially abut against each other and stack together, rising and sliding onto the four vertical support rods. This controls the row of safety guard frames 3 to disengage from the distribution cabinet body 1 and release the cabinet door, enabling the cabinet door to be opened. When the bottom safety protection frame 3 slides down, the row of safety protection frames 3 can slide down and fit onto the power distribution cabinet body 1 by their own gravity. In this invention, the rotation and release of the two lifting steel wire ropes 5 can be controlled by two hand-cranked turntables 104 to control the fitting and disengagement of the row of safety protection frames 3 with the power distribution cabinet body 1. Through two inserts, the L-shaped insert rod 107 can be inserted and positioned by the left hand-cranked turntable 104 and the right hand-cranked turntable 104, so that the row of safety protection frames 3 is kept in the state of sliding upward with the power distribution cabinet body 1.

[0048] The guide 103 has a smooth surface and arc guiding characteristics, which can avoid damage to the cable by pressing against it and can effectively reduce the frictional resistance between the cable and the side of the cable tray when the cable is threaded through. The four sets of rocker arms 102, four threaded blocks 202 and two mounting plates 101 are connected to form four sets of crank-slider mechanisms. Through these four mechanisms, the four threaded blocks 202 can slide back and forth synchronously, which can drive the two mounting plates 101 and the power distribution cabinet body 1 to slide up and down. The four sets of crank-slider mechanisms are used as the base support of the power distribution cabinet body 1.
