Description

Technical Field

[0001] This invention belongs to the field of distribution box technology, specifically relating to a distribution box with outdoor protection function. Background Technology

[0002] Outdoor distribution boxes are electrical devices specifically designed for outdoor environments. They are primarily used to stably and safely distribute electrical energy and control related equipment under harsh weather conditions. They can operate normally in various extreme weather conditions. An outdoor distribution box assembles switching equipment, measuring instruments, protective devices, and auxiliary equipment according to electrical wiring requirements within a closed or semi-closed metal cabinet or panel, forming a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected manually or automatically. In the event of a fault or abnormal operation, the protective devices will cut off the circuit or issue an alarm.

[0003] A search revealed that patent document CN118156986A discloses an energy-saving waterproof canopy for outdoor distribution boxes, relating to the field of distribution box protection technology. The canopy includes a main body of the distribution box, with top plates at both ends. Solar panels are mounted on the surfaces of both top plates. Fixing blocks are fixedly connected to the four corners of the upper surface of the main body, and two parallel fixing rods are mounted on the upper surface. Rotating columns are mounted at the front and rear ends of the two fixing rods. When the two top plates are in an extended state, the four supporting columns are vertically downward. Telescopic columns, which are movably connected to the supporting columns, descend due to gravity, bringing their lower surfaces into contact with the ground. The four telescopic columns and the four supporting columns provide support for the two top plates, preventing them from being easily subjected to wind pressure in windy weather. The high center of gravity makes the distribution box more prone to losing balance, reducing the possibility of the distribution box being overturned.

[0004] While the aforementioned patents achieve the purpose of providing rain protection, they face numerous limitations in practical applications. They cannot effectively solve the problem of rain protection for maintenance personnel when inspecting distribution boxes. In other words, existing technologies use completely passive, fixed rain shelters installed on both sides of the distribution box. This increases usage costs and significantly reduces applicability. Furthermore, due to the unpredictable nature of rainy weather, when rain falls at an angle, the fixed rain shelters installed on both sides of the distribution box cannot adapt, allowing large amounts of rainwater to directly impact the box, thus failing to provide effective rain protection. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a distribution box with outdoor protection functions. This effectively solves the problem that existing technologies use completely passive, fixed rain shelters installed on both sides of the distribution box for rain protection. This increases usage costs, significantly reduces applicability, and is further hampered by the unpredictable nature of rainy weather. When rain blows at an angle, the fixed rain shelters installed on both sides of the distribution box cannot be adjusted to adapt, allowing a large amount of rainwater to directly impact the box, thus failing to provide effective rain protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distribution box with outdoor protection function, comprising a box body and a door hinged to one side of the box body, and further comprising: a movable module installed on the top of the box body; a protective module disposed on the top of the movable module; and a housing fixedly connected to the top of the protective module and sleeved on the outside of the protective module and the movable module; wherein the protective module comprises a closed compartment, both sides of the closed compartment are fixedly connected with toothed plates, the top of the toothed plates engages with a connecting roller located inside the closed compartment, the outer wall of the connecting roller is covered with a hydrophobic cloth, both ends of the connecting roller are movably sleeved with connecting rods, one end of the connecting rod abutting abutment; the movable module comprises a pad, the top of the pad is slidably engaged with a plurality of abutment plates, the top of the abutment plates is hinged to the bottom of the closed compartment, the outer side of the abutment plates abuts abutting rod, the abutting rod abuts abutting a first bracket through an inclined plate, and the end of the first bracket away from the inclined plate is fixedly connected to a second bracket slidably connected to the connecting rod.

[0007] Preferably, the door is hinged to the box body via a pivot, and spring plates for resetting the door are fitted on the outer walls of both ends of the pivot.

[0008] The top of the door hinge extends into the interior of the movable module and is fixedly connected to an abutment.

[0009] Preferably, the abutment is composed of a semi-circular cam and a telescopic cylinder. The outer cylinder of the telescopic cylinder is fixedly connected to the pivot of the door, the inner cylinder of the telescopic cylinder is rotatably connected to the interior of the sealed chamber, and the outer wall of the outer cylinder of the telescopic cylinder is fixedly connected to the semi-circular cam.

[0010] Preferably, a cover plate is hinged to the side of the sealed chamber near the door, and oblique air grooves for the circulation of gas inside the sealed chamber are provided on both sides of the sealed chamber and the shell.

[0011] The bottom surface of the inner cavity of the sealed chamber is inclined, and the lower end is located on the side away from the door. When the hydrophobic cloth is taken into the interior of the sealed chamber, the residual rainwater will be discharged out quickly through the inclined state of the bottom surface of the inner cavity of the sealed chamber. The inclined air grooves on the sealed chamber and the shell will accelerate the discharge rate and drying effect of the rainwater inside the sealed chamber.

[0012] Preferably, the connecting roller consists of two mutually engaging connecting rollers and spur gears sleeved on both ends of the outer side of the connecting rollers;

[0013] The outer wall of the spur gear meshes with the toothed plate, and the two ends of the connecting roller are also movably sleeved with the connecting rod that abuts against the contacting member;

[0014] The hydrophobic cloth is fitted with a counterweight at the contact end with the bottom of the sealed chamber cavity. Since the spur gear on the connecting roller only meshes with the toothed plate, and the sealed chamber cavity has ample space to allow the connecting roller to move back and forth inside the sealed chamber.

[0015] Preferably, the contact end of the connecting rod and the semi-circular cam of the abutment is provided with an angle, and a transverse groove is provided inside one side of the connecting rod to allow the second bracket to move through. When the semi-circular cam on the abutment rotates, it will move towards the box door by abutting the connecting rod through the angled end of the connecting rod, and then drive the hydrophobic cloth inside the sealed compartment to move towards the box door through the connecting roller.

[0016] Preferably, the bottom surface of the enclosed chamber is provided with a plurality of limiting rods that hinge and limit the top of the abutment plate; the four corners of the bottom surface of the enclosed chamber are provided with spring telescopic cylinders that are elastically connected to the pad plate.

[0017] Preferably, the top of the pad is provided with several straight grooves for moving the abutment plate and the abutment rod, and two abutment rods are provided, which are elastically connected by an elastic element;

[0018] The contact end between the inclined plate and the first bracket is provided with an angle;

[0019] The second bracket has an angled end at the contact end with the abutment, and after the second bracket is abutted by the abutment, it can move into the transverse groove of the connecting rod.

[0020] Preferably, the pad is movably connected to a baffle, and both ends of the baffle are provided with several rubber wheels.

[0021] The present invention also provides a method for using a distribution box with outdoor protection function, the method comprising the following steps:

[0022] S1, When inspecting the inside of the enclosure in rainy weather, flip the enclosure door open to make the rotating shaft rotate. The rotating shaft will drive the contact part to rotate and make the contact part gradually press against the connecting rod, causing the connecting rod to move.

[0023] S2, when the connecting rod is pushed towards the door, the upper end of the connecting rod will push the connecting roller to move, and through the meshing of the spur gear on the connecting roller with the toothed plate, the hydrophobic cloth will be loosened first inside the closed chamber.

[0024] S3, pull the baffle outward and flip the cover of the sealed chamber upward, pull the counterweight at the bottom of the hydrophobic cloth and make the inner side of the hydrophobic cloth contact the end of the baffle. Under the gravity of the counterweight and the obstruction of the pulled-out baffle, the hydrophobic cloth will be vertically unfolded in the back area of ​​the maintenance personnel, and will not be in close contact with the back of the maintenance personnel in a large area, causing discomfort.

[0025] S4, the semi-circular protrusion of the abutment will abut the second bracket after abutting the connecting rod. The inclined surface of the second bracket will cause it to move towards the two abutments through the first bracket and the inclined plate. When the two abutments move towards each other, the contact end of the abutment and the abutment plate will abut the abutment plate, causing the abutment plate to gradually change from an inclined state to a vertical state, thereby driving the entire protective module to move upward.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] (1) The present invention provides a distribution box with outdoor protection function, which can effectively protect the distribution box from rain during outdoor maintenance. No matter what state the rain hits, it can completely protect the box from rain, thereby reducing the cost of use and greatly improving its applicability.

[0028] (2) Through the coordinated operation of the contact element, connecting rod, hydrophobic cloth and connecting roller, the present invention can achieve comprehensive rain protection for maintenance personnel without requiring excessive physical labor. It can also loosen the hydrophobic cloth before it is fully pushed out, saving unfolding time. Specifically, the rotating shaft drives the semi-circular cam to rotate through the outer cylinder of the contact element telescopic cylinder, so that the semi-circular cam moves towards the door of the box by contacting the connecting rod. The upper end of the connecting rod pushes the connecting roller to move and mesh with the toothed plate, so that the hydrophobic cloth is loosened first inside the closed chamber. The counterweight is pulled down, so that the hydrophobic cloth is vertically unfolded in the back area of ​​the maintenance personnel, providing quick and comprehensive rain protection with high flexibility.

[0029] (3) Through the coordinated cooperation of the abutment plate, abutment rod, inclined plate and second support, the present invention can not only improve the rain-proof height range of the hydrophobic cloth by raising the entire protective module, but also adapt to the box of different heights. When the box height is low, when the maintenance personnel are in a squatting position, the protective module can be raised to be higher than the head of the squatting maintenance personnel for rain protection. Specifically, after the semi-circular protrusion of the abutment member abuts the connecting rod, it will abut the second support, causing it to move towards the two abutment rods through the first support and inclined plate, so that the contact end of the abutment rod and the abutment plate abuts the abutment plate, causing the abutment plate to gradually change from an inclined state to a vertical state, thereby driving the entire protective module to move upward, thereby improving the overall applicability.

[0030] (4) The present invention, through the synergistic cooperation of the baffle, the pad and the hydrophobic cloth, can not only prevent the inner wall of the hydrophobic cloth from being too close to the back of the maintenance personnel due to the impact of rainwater when using the hydrophobic cloth for rain protection, thus preventing discomfort, but also provides an additional auxiliary covering effect above the box. The embedded design reduces the cost of use. Specifically, the baffle is pulled outward from the inside of the pad, so that one end of the baffle comes into contact with the hydrophobic cloth. The rubber wheels on both sides of the baffle increase the friction between the baffle and the inner wall of the pad, preventing the baffle from moving back and forth randomly after being pulled out. The length of the baffle pulled outward can also be determined according to the size of the maintenance personnel, thus improving the rain protection effect. Attached Figure Description

[0047] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" indicate orientation or positional relationships only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0048] It should be understood that, in the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” and “linking” should be interpreted broadly.

[0049] Example 1: As Figures 1 to 13As shown, the present invention provides a distribution box with outdoor protection function, including a box body 100 and a door 200 hinged to one side of the box body 100, and further including: a movable module 500, which is installed on the top of the box body 100; a protective module 400, which is disposed on the top of the movable module 500; and a housing 300, which is fixed to the top of the protective module 400 and sleeved on the outside of the protective module 400 and the movable module 500; wherein the protective module 400 includes a closed compartment 410, and toothed plates 450 are fixedly connected to both sides of the closed compartment 410, and the top of the toothed plates 450 engages with a connecting roller 4 located inside the closed compartment 410. 20. A hydrophobic cloth 430 is sleeved on the outer wall of the connecting roller 420. A connecting rod 440 is movably sleeved at both ends of the connecting roller 420. One end of the connecting rod 440 abuts against a contact member 460. The movable module 500 includes a pad 510. Several abutments 520 are slidably engaged at the top of the pad 510. The top of the abutment 520 is hinged to the bottom of the closed chamber 410. An abutment rod 540 abuts against the outer side of the abutment 520. The abutment rod 540 abuts against a first bracket 560 through an inclined plate 550. A second bracket 570 is fixedly connected to the end of the first bracket 560 away from the inclined plate 550 and slidably connected to the connecting rod 440.

[0050] The door 200 is hinged to the box body 100 via a pivot, and spring plates that allow the door 200 to return to its original position are fitted on the outer walls of both ends of the pivot.

[0051] The top of the hinge of the door 200 extends into the interior of the movable module 500 and is fixedly connected to the abutment 460.

[0052] The contact element 460 consists of a semi-circular cam and a telescopic cylinder. The outer cylinder of the telescopic cylinder is fixedly connected to the pivot of the door 200, the inner cylinder of the telescopic cylinder is rotatably connected to the interior of the closed chamber 410, and the outer wall of the outer cylinder of the telescopic cylinder is fixedly connected to the semi-circular cam.

[0053] It is not difficult to understand that, combined Figure 4 It can be seen that the pivot on the door 200 is fixedly connected to the outer cylinder of the telescopic cylinder on the contact part 460, which causes the pivot to drive the semi-circular cam to rotate through the outer cylinder of the telescopic cylinder when the door 200 rotates. At the same time, due to the limitation of the movable connection between the inner and outer cylinders of the telescopic cylinder, the inner cylinder will not rotate when the outer cylinder rotates.

[0054] A cover plate is hinged to the side of the sealed chamber 410 near the door 200. Both sides of the sealed chamber 410 and the shell 300 are provided with inclined air slots for the circulation of gas inside the sealed chamber 410.

[0055] The bottom surface of the inner cavity of the sealed compartment 410 is inclined, and the lower end is located on the side away from the door 200.

[0056] Combination Figure 2 and Figure 3It can be concluded that the height of the inner cavity of the sealed chamber 410 is the highest on the side near the door 200 and the lowest on the other side. When the hydrophobic cloth 430 is taken into the interior of the sealed chamber 410, the residual rainwater will be discharged out quickly through the inclined state of the bottom surface of the inner cavity of the sealed chamber 410. The rainwater discharge rate and drying effect inside the sealed chamber 410 are accelerated by the inclined air grooves on the sealed chamber 410 and the shell 300.

[0057] The connecting roller component 420 consists of two mutually movable and interlocking connecting rollers and spur gears sleeved on both ends of the outer side of the connecting rollers;

[0058] The outer wall of the spur gear meshes with the tooth plate 450, and the two ends of the connecting roller are also movably sleeved with the connecting rod 440 that abuts against the contacting member 460;

[0059] A counterweight is installed at the contact end between the hydrophobic fabric 430 and the bottom surface of the inner cavity of the sealed chamber 410.

[0060] When the hydrophobic cloth 430 needs to be replaced, since the spur gear on the connecting roller 420 only engages with the toothed plate 450, and the inner cavity of the sealed chamber 410 has ample space for the connecting roller 420 to move back and forth inside the sealed chamber 410, and combined with Figure 10 It can be seen that the connecting rod 440 and the semi-circular cam of the contacting part 460 are not in contact in the initial situation, and there is a space at one end. At this time, the connecting roller on one side can be pushed away from the box door 200, which will separate the two connecting rollers and allow the hydrophobic cloth 430 to be easily removed from the outer wall of the connecting roller 420.

[0061] When one end of the hydrophobic cloth 430 is taken out from inside the sealed chamber 410, the counterweight of the hydrophobic cloth 430 will cause the hydrophobic cloth 430 to quickly unfold vertically.

[0062] The contact end of the connecting rod 440 and the semi-circular cam of the abutment 460 is provided with an angle, and a transverse groove is provided inside one side of the connecting rod 440 to allow the second bracket 570 to move through.

[0063] When the semi-circular cam on the contact member 460 rotates, it will move towards the door 200 by contacting the connecting rod 440 through the angled end of the connecting rod 440, and then drive the hydrophobic cloth 430 to move towards the door 200 inside the closed chamber 410 through the connecting roller 420.

[0064] The bottom surface of the enclosed chamber 410 is provided with several limiting rods that are hinged to limit the top of the abutment plate 520; the four corners of the bottom surface of the enclosed chamber 410 are provided with spring telescopic cylinders that are elastically connected to the pad plate 510.

[0065] The top of the pad 510 is provided with several straight grooves that allow the abutment plate 520 and the abutment rod 540 to move. There are two abutment rods 540, and the two abutment rods 540 are elastically connected by an elastic member 530.

[0066] The contact end between the inclined plate 550 and the first bracket 560 is provided with an angle;

[0067] The second bracket 570 and the contact end of the contact member 460 are provided with an angle, and after the second bracket 570 is contacted by the contact member 460, it can move into the transverse groove of the connecting rod 440.

[0068] The pad 510 is internally connected to a baffle 580, and both ends of the baffle 580 are provided with several rubber wheels.

[0069] Pulling the baffle 580 outward from inside the pad 510 allows the inner wall of the hydrophobic cloth 430 to come into contact with the end of the baffle 580. The rubber wheels on both sides of the baffle 580 increase the friction between the baffle 580 and the inner wall of the pad 510, preventing the baffle 580 from moving back and forth randomly after being pulled out. The length of the baffle 580 pulled outward can be determined according to the size of the maintenance personnel, so that the hydrophobic cloth 430 will not stick tightly to the back of the maintenance personnel when it is vertically unfolded. It should be noted that the hydrophobic cloth 430 can be made of hydrophobic material, and the specific length can be adjusted according to the actual application.

[0070] The present invention also provides a method for using a distribution box with outdoor protection function, the method comprising the following steps:

[0071] S1, When performing maintenance on the inside of the housing 100 in rainy weather, flip open the housing door 200 to make it rotate the shaft. The shaft will drive the contact member 460 to rotate and make the contact member 460 gradually press against the connecting rod 440, causing the connecting rod 440 to move.

[0072] S2, when the connecting rod 440 is pushed towards the door 200, the upper end of the connecting rod 440 will push the connecting roller 420 to move, and through the meshing of the spur gear on the connecting roller 420 with the toothed plate 450, the hydrophobic cloth 430 will be loosened first inside the closed chamber 410.

[0073] S3, pull the baffle 580 outward and flip the cover of the closed chamber 410 upward, pull the counterweight at the bottom of the hydrophobic cloth 430 and make the inner side of the hydrophobic cloth 430 contact the end of the baffle 580. Under the gravity of the counterweight and the obstruction of the pulled-out baffle 580, the hydrophobic cloth 430 will be vertically unfolded and located in the back area of ​​the maintenance personnel, and will not be in close contact with the back of the maintenance personnel in a large area, causing discomfort.

[0074] S4, after the semi-circular protrusion of the contact member 460 abuts the connecting rod 440, it will abut the second bracket 570. The inclined surface of the second bracket 570 causes it to move towards the two abutting rods 540 through the first bracket 560 and the inclined plate 550. When the two abutting rods 540 move towards each other, the contact end of the abutting rod 540 and the abutting plate 520 will abut the abutting plate 520, causing the abutting plate 520 to gradually change from an inclined state to a vertical state, thereby driving the entire protective module 400 to move upward.

[0075] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

The rotating shaft will cause the contact part (460) to rotate, and the contact part (460) will gradually press against the connecting rod (440), causing the connecting rod (440) to move. S2, when the connecting rod (440) is pushed towards the door (200) by the contact, the upper end of the connecting rod (440) will push the connecting roller (420) to move, and through the meshing of the spur gear on the connecting roller (420) and the toothed plate (450), the hydrophobic cloth (430) will be loosened first inside the closed chamber (410); S3, pull out the baffle (580) and flip the cover of the closed chamber (410) upward, pull the counterweight at the bottom of the hydrophobic cloth (430) and make the inner side of the hydrophobic cloth (430) contact the end of the baffle (580). Under the gravity of the counterweight and the obstruction of the pulled-out baffle (580), the hydrophobic cloth (430) will be vertically unfolded in the back area of ​​the maintenance personnel, and will not be in close contact with the back of the maintenance personnel in a large area, causing discomfort. S4, the semi-circular protrusion of the contact member (460) will abut against the second bracket (570) after abutting the connecting rod (440). The inclined surface of the second bracket (570) will cause it to abut against the two abutting rods (540) and move towards each other through the first bracket (560) and the inclined plate (550). When the two abutting rods (540) move towards each other, the contact end of the abutting rod (540) and the abutting plate (520) will abut against the abutting plate (520), so that the abutting plate (520) will gradually change from the inclined state to the vertical state, thereby driving the entire protective module (400) to move upward.
