Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and more particularly to a waterproof structure for a distribution box. Background Art

[0002] A distribution box generally consists of a box body, switching appliances, protective appliances, measuring instruments, connecting busbars, etc. The outer shell of the distribution box serves to protect the internal electrical components and prevent electric shock to personnel. The box body is usually made of metal or plastic and has a certain strength and protection level. For example, in some outdoor distribution boxes, the protection level of the box body is relatively high, which can prevent rainwater, dust, etc. from entering the box to ensure the normal operation of the internal electrical equipment.

[0003] Currently, the common waterproof measures for outdoor distribution boxes on the market mainly install rain shields outside the ventilation holes. The rain shields are generally inclined, similar to a small roof, which can guide rainwater to slide off from the side and prevent rainwater from directly entering the ventilation holes vertically. However, in windy conditions, the rainwater will be blown towards the rain shield of the ventilation hole of the distribution box, and the rainwater will directly impact the rain shield of the ventilation hole. Due to the certain speed and momentum of the rainwater, splashing will occur after the impact, and some of the splashed water droplets may enter the distribution cabinet through the holes of the ventilation hole. Summary of the Invention

[0004] The present application provides a waterproof structure for a distribution box, which covers the ventilation hole of the distribution box by closing the air inlet hole of the protective cover when it rains, so as to avoid the situation that rainwater enters the distribution box from the ventilation hole, and solve the problems raised in the above background art.

[0005] A waterproof structure for a distribution box provided by the present application adopts the following technical solutions: A waterproof structure for a distribution box, comprising a box body, a box door is installed on the surface of the box body, a top plate is installed on the upper surface of the box body, a plurality of exhaust holes are opened on the surface of the top plate, ventilation holes are opened on both sides of the box body, and shielding structures are provided on both sides of the box body. The shielding structure includes a protective cover, the protective cover is fixedly connected to the surface of the box body, the protective cover covers the ventilation holes, a plurality of air inlet holes are opened on the surface of the protective cover, a rectangular groove is opened on one side of the inner wall of each of the plurality of air inlet holes, two rectangular holes are opened on the surface of the protective cover, the rectangular holes communicate with the plurality of rectangular grooves, baffles are slidably inserted into the inner walls of the plurality of rectangular grooves, the size of the baffles is adapted to the size of the air inlet holes, traction belts are slidably inserted into the inner walls of the two rectangular holes, both traction belts are fixedly connected to the plurality of baffles, a frame is fixedly connected to the surface of the box body, two sliders are slidably connected to the surface of the frame, a rectangular box is fixedly connected to one side of the two sliders close to each other, and both ends of the traction belts away from the baffles are fixedly connected to the rectangular box. Two drain holes are opened on the surface of the rectangular box.

[0006] By adopting the above technical solutions, it is convenient to cover the ventilation holes, thereby avoiding rainwater splashing into the box body from the ventilation holes, and further avoiding the components in the box body from being damaged due to rainwater entering the box body.

[0007] Preferably, four fixing plates are fixedly connected to the surface of the frame. The four fixing plates are divided into two groups. One group of fixing plates is rotatably connected with a rotating wheel on one side close to each other.

[0008] By adopting the above technical solutions, when the traction belt moves, it will slide along the surface of the rotating wheel. The rotating wheel will rotate on the surface of the fixing plate by means of the sliding force of the traction belt. The rotating wheel supports the traction belt, thereby avoiding the situation that the traction belt gets stuck due to excessive friction between the traction belt and the surface of the frame when the traction belt slides along the surface of the frame.

[0009] Preferably, two extension pipes are fixedly connected to the surface of the frame, and the size of the extension pipes is adapted to the size of the drain holes.

[0010] By adopting the above technical solutions, the extension pipes will be inserted into the water inlet holes. The extension pipes limit the drainage position of the drain holes, thereby avoiding the rainwater in the drain holes from dripping onto the surface of the distribution box again.

[0011] Preferably, one end of the traction belt away from the rectangular box is fixedly connected with a rope, and the other end of the rope is fixedly connected with a plumb bob.

[0012] By adopting the above technical solutions, the plumb bob will pull the rope by its own weight, and the rope will pull the traction belt, thereby applying gravity to the traction belt, and further facilitating the reset of the baffle and the traction belt.

[0013] Preferably, the surface of the extension pipe is provided with an auxiliary structure. The auxiliary structure includes two connection chambers. The two connection chambers are respectively communicated with the two extension pipes. The inner wall of the connection chamber is rotatably connected with an impeller. One side of the impeller is fixedly connected with a drive shaft. The drive shaft rotatably penetrates through the connection chamber. The inner wall of the protective cover is fixedly connected with a rectangular plate. The surface of the rectangular plate is rotatably connected with two round rods. One end of the round rod is fixedly connected with a bevel gear B. The two sides of the protective cover are both rotatably penetrated by a transmission shaft. One end of the transmission shaft close to the round rod is fixedly connected with a bevel gear A. The bevel gear A is meshed with the bevel gear B. One end of the transmission shaft and the drive shaft are both fixedly connected with a transmission wheel. The surface of the two transmission wheels is sleeved with a transmission belt. One end of the round rod far from the bevel gear B is fixedly connected with a fan blade.

[0014] By adopting the above technical solution, it is achieved that the rotation of the fan blade is driven by the flow of rainwater in the extension pipe. The rotation of the fan blade will suck air into the protective cover, thereby improving the efficiency of air entering the protective cover, and further ensuring the ventilation effect of the ventilation holes.

[0015] Preferably, two extension blocks are fixedly connected to one side of the rectangular plate. Two V-shaped plates are fixedly connected to the side of the two extension blocks far from the rectangular plate.

[0016] By adopting the above technical solution, when the air enters the protective cover, it will blow towards the rectangular plate. Since the V-shaped plate is fixed on the surface of the rectangular plate, the flow direction of the air is shunted, avoiding further improving the air flow effect.

[0017] Preferably, a filter screen is fixedly connected to the inner wall of the protective cover.

[0018] By adopting the above technical solution, the filter screen will filter the air sucked into the protective cover, thereby avoiding the effect that dust enters the protective cover along with the air.

[0019] Preferably, a cleaning structure is provided on the surface of the top plate. The cleaning structure includes a plurality of grooves. The plurality of grooves are respectively opened on both sides of the top plate. The inner walls of the two symmetrically opened grooves are rotatably connected with a rotating plate. A plurality of push rods slidably penetrate through the surface of the top plate. A ring is fixedly connected to the surface of the push rod. A spring is sleeved on the surface of the push rod. The two ends of the spring are respectively fixedly connected with the ring and the top plate. One side of the rotating wheel is fixedly connected with a cam.

[0020] By adopting the above technical solution, it is achieved that the fallen leaves or impurities on the top plate are conveniently removed, thereby avoiding the accumulation of fallen leaves and other impurities on the surface of the top plate, resulting in the corrosion of the surface of the top plate.

[0021] Preferably, balls are rotatably connected to both ends of the push rod.

[0022] By adopting the above technical solution, the ball reduces the friction force of the push rod when the cam and the rotating plate avoid moving, so as to facilitate the cam to drive the rotating plate to rotate by means of the push rod.

[0023] Preferably, an elastic cloth is fixedly connected to one side of the two rotating plates close to each other.

[0024] By adopting the above technical solution, the rotating plate will rotate and reset by virtue of its own weight and the elastic force of the elastic cloth. The elastic cloth facilitates the reset angle of the rotating plate, and further facilitates the covering of the gap between the two rotating plates after rotation, avoiding impurities from entering the position between the rotating plate and the top plate.

[0025] In summary, the present application has the following beneficial effects: 1. By setting the shielding structure, the ventilation holes can be covered to prevent rainwater from splashing into the box through the ventilation holes, thus avoiding the situation of rainwater entering the interior and causing damage. Then, an extension pipe is used to connect the drainage holes, so as to prevent rainwater from dripping on the surface of the frame and splashing onto the surface of the box again, further improving the waterproof effect of the distribution box; 2. By setting the auxiliary structure, the rotation of the fan blade is driven by the flow of rainwater in the extension pipe. The rotation of the fan blade will suck air into the protective cover, thus improving the efficiency of air entering the protective cover, and further ensuring the ventilation effect of the ventilation holes. A filter screen is also provided on the inner wall of the protective cover to filter the air entering the protective cover, and then filter out the dust in the air to prevent dust from entering the box through the ventilation holes; 3. By setting the cleaning structure, the rotation of the rotating plate is driven by the rotation of the runner, so as to facilitate the removal of fallen leaves or impurities floating on the top plate, and further avoid the accumulation of fallen leaves and other impurities on the surface of the top plate, resulting in the corrosion of the surface of the top plate.

Detailed implementation manners

[0028] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] The present invention discloses a waterproof structure for a distribution box, as Figures 1-7As shown in the figure, it includes a box body 1. A box door 2 is installed on the surface of the box body 1. A top plate 3 is installed on the upper surface of the box body 1. A number of exhaust holes 4 are opened on the surface of the top plate 3. Ventilation holes 5 are opened on both sides of the box body 1. Shielding structures 6 are provided on both sides of the box body 1. The shielding structure 6 includes a protective cover 601. The protective cover 601 is fixedly connected to the surface of the box body 1. The protective cover 601 covers the ventilation holes 5. A number of air inlet holes 602 are opened on the surface of the protective cover 601. A rectangular groove 603 is opened on one side of the inner wall of each of the number of air inlet holes 602. Two rectangular holes 604 are opened on the surface of the protective cover 601. The rectangular holes 604 communicate with the number of rectangular grooves 603. A baffle 605 is slidably inserted into the inner wall of each of the number of rectangular grooves 603. The size of the baffle 605 is adapted to the size of the air inlet hole 602. A traction belt 606 is slidably inserted into the inner wall of each of the two rectangular holes 604. Both of the two traction belts 606 are fixedly connected to the number of baffles 605. A frame 607 is fixedly connected to the surface of the box body 1. Two sliders 608 are slidably connected to the surface of the frame 607. A rectangular box 609 is fixedly connected to the side of the two sliders 608 close to each other. One end of each of the two traction belts 606 away from the baffle 605 is fixedly connected to the rectangular box 609. Two drain holes 610 are opened on the surface of the rectangular box 609, achieving the function of facilitating the covering of the ventilation holes 5, thereby preventing rainwater from splashing into the box body 1 through the ventilation holes 5, and further preventing rainwater from entering the box body 1 and causing damage to the components inside the box body 1.

[0030] As Figures 1-7 shown, four fixing plates 611 are fixedly connected to the surface of the frame 607. The four fixing plates 611 are divided into two groups. One group of fixing plates 611 is rotatably connected to a runner 612 on the side close to each other. When the traction belt 606 moves, it will slide along the surface of the runner 612. The runner 612 will rotate on the surface of the fixing plate 611 by means of the sliding force of the traction belt 606. The runner 612 achieves the support for the traction belt 606, thereby preventing the situation that the traction belt 606 gets stuck due to excessive friction with the surface of the frame 607 when sliding along the surface of the frame 607. Two extension pipes 613 are fixedly connected to the surface of the frame 607. The size of the extension pipe 613 is adapted to the size of the drain hole 610. The extension pipe 613 will be inserted into the water inlet hole. The extension pipe 613 achieves the limitation of the drainage position of the drain hole 610, thereby preventing the rainwater in the drain hole 610 from dripping onto the surface of the distribution box again. One end of the traction belt 606 away from the rectangular box 609 is fixedly connected to a rope 614. The other end of the rope 614 is fixedly connected to a plumb bob 615. The plumb bob 615 will pull the rope 614 by its own weight. The rope 614 will pull the traction belt 606, thereby applying gravity to the traction belt 606, and further facilitating the reset of the baffle 605 and the traction belt 606.

[0031] Combined with the attached Figure 8 and the attached Figure 9and the attached drawings Figure 10 As shown, to improve the efficiency of air entering the protective cover 601 after passing through the air inlet holes 602 of the closed protective cover 601, an auxiliary structure 7 is provided on the surface of the extension pipe 613. The auxiliary structure 7 includes two connection chambers 701, and the two connection chambers 701 are respectively communicated with the two extension pipes 613. An impeller 702 is rotatably connected to the inner wall of the connection chamber 701. One side of the impeller 702 is fixedly connected to a drive shaft 703. The drive shaft 703 rotates through the connection chamber 701. A rectangular plate 708 is fixedly connected to the inner wall of the protective cover 601. Two round rods 709 are rotatably connected to the surface of the rectangular plate 708. One end of the round rod 709 is fixedly connected to a bevel gear B710. The two sides of the protective cover 601 are respectively penetrated by a transmission shaft 706. One end of the transmission shaft 706 close to the round rod 709 is fixedly connected to a bevel gear A707. The bevel gear A707 meshes with the bevel gear B710. One end of each of the transmission shaft 706 and the drive shaft 703 is fixedly connected to a transmission wheel 704. A transmission belt 705 is sleeved on the surfaces of the two transmission wheels 704. One end of the round rod 709 away from the bevel gear B710 is fixedly connected to a fan blade 711. By means of the flow of rainwater in the extension pipe 613, the fan blade 711 is driven to rotate. The rotation of the fan blade 711 will suck air into the protective cover 601, thereby improving the efficiency of air entering the protective cover 601 and further ensuring the ventilation effect of the ventilation holes 5. Two extension blocks 712 are fixedly connected to one side of the rectangular plate 708. A V-shaped plate 713 is fixedly connected to one side of the two extension blocks 712 away from the rectangular plate 708. When the air enters the protective cover 601, it will blow towards the rectangular plate 708. Since the V-shaped plate 713 is fixed on the surface of the rectangular plate 708, the flow direction of the air is diverted, avoiding further improving the air flow effect. A filter screen 714 is fixedly connected to the inner wall of the protective cover 601. The filter screen 714 will filter the air sucked into the protective cover 601, thereby preventing dust from entering the protective cover 601 along with the air.

[0032] Combined with the attached drawings Figure 5 and the attached drawings Figure 11 and the attached drawings Figure 12As shown in the figure, in order to further remove the fallen leaves and impurities on the top plate 3, a cleaning structure 8 is provided on the surface of the top plate 3. The cleaning structure 8 includes a number of grooves 81, and a number of grooves 81 are respectively opened on both sides of the top plate 3. The inner walls of two symmetrically opened grooves 81 are rotatably connected with rotating plates 82. A number of push rods 83 penetrate through the surface of the top plate 3 in a sliding manner. A ring 84 is fixedly connected to the surface of the push rod 83. A spring 85 is sleeved on the surface of the push rod 83. The two ends of the spring 85 are respectively fixedly connected with the ring 84 and the top plate 3. A cam 86 is fixedly connected to one side of the runner 612, so as to facilitate the removal of the fallen leaves or impurities floating on the top plate 3, thereby avoiding the accumulation of fallen leaves and other impurities on the surface of the top plate 3, resulting in the corrosion of the surface of the top plate 3. Both ends of the push rod 83 are rotatably connected with balls 87. The balls 87 are used to reduce the friction force of the push rod 83 when moving on the cam 86 and the rotating plate 82, so as to facilitate the cam 86 to drive the rotating plate 82 to rotate by means of the push rod 83. An elastic cloth 88 is fixedly connected to the side of the two rotating plates 82 close to each other. The rotating plate 82 will rotate and reset by virtue of its own weight and the elastic force of the elastic cloth 88 when it rebounds. The elastic cloth 88 is used to facilitate the reset angle of the rotating plate 82, and further facilitate the covering of the gap between the two rotating plates 82 after rotation, so as to prevent impurities from entering the position between the rotating plate 82 and the top plate 3.

[0033] Working principle: Since the weight of the rectangular box 609 is slightly lighter than that of the multiple baffles 605, the rectangular box 609 will be pulled up in the frame 607 by the baffles 605 with the help of the traction belt 606. When it rains, rainwater will drip into the rectangular box 609. As the rainwater in the rectangular box 609 increases, the rainwater in the rectangular box 609 will drain out from the drainage holes 610 opened on the surface. When the efficiency of the dripping rainwater is greater than the drainage efficiency, the weight of the rectangular box 609 will increase accordingly. When the rainwater in the rectangular box 609 reaches a certain weight, the rectangular box 609 will drive the slider 608 to slide in the frame 607. The movement of the rectangular box 609 will pull the two traction belts 606. The movement of the traction belt 606 will slide along the surface of the runner 612. The runner 612 will rotate on the surface of the fixed plate 611 by means of the sliding force of the traction belt 606. The runner 612 is used to support the traction belt 606, thus avoiding the situation that the traction belt 606 gets stuck due to excessive friction between the traction belt 606 and the surface of the frame 607 when the traction belt 606 slides along the surface of the frame 607. The movement of the traction belt 606 will slide in the rectangular hole 604. The movement of the traction belt 606 will simultaneously pull the multiple baffles 605. The movement of the baffles 605 will gradually disengage from the rectangular groove 603. The baffles 605 will gradually cover the water inlet holes. The traction belt 606 will also pull the rope 614 while moving. The rope 614 will drive the lead block to move. When the baffles 605 completely cover the water inlet holes, it can prevent rainwater from entering the protective cover 601 from the water inlet holes, and further prevent rainwater from entering the box body 1 from the ventilation holes 5. Air will enter from the lower side of the protective cover 601, thus protecting the ventilation holes 5 from rainwater while ensuring their ventilation effect. The extension pipe 613 will be inserted into the water inlet holes. The extension pipe 613 can limit the drainage position of the drainage holes 610, thus preventing the rainwater in the drainage holes 610 from dripping onto the surface of the distribution box again. When the rain stops, the water in the rectangular box 609 will gradually drain out through the drainage holes 610. As the rainwater in the rectangular box 609 decreases, the weight of the rectangular box 609 will decrease accordingly. At this time, the baffles 605 will drive the rectangular box 609 to reset by their own weight. At this time, the plumb bob 615 will pull the rope 614 by its own weight. The rope 614 will pull the traction belt 606, thus applying gravity to the traction belt 606, which is convenient for resetting the baffles 605 and the traction belt 606.

[0034] When rainwater is discharged through the extension pipe 613, the rainwater will enter the connection chamber 701 from the extension pipe 613. The rainwater entering the connection chamber 701 will impact on the surface of the impeller 702. The impeller 702 will rotate by means of the impact of the rainwater. The rotation of the impeller 702 will drive the rotation of the drive shaft 703. The rotation of the drive shaft 703 will drive the rotation of the transmission wheel 704. The rotation of the transmission wheel 704 will drive the rotation of another transmission wheel 704 by means of the transmission belt 705. The transmission wheel 704 will drive the rotation of the transmission shaft 706 by the force of the transmission belt 705. The rotation of the transmission shaft 706 will drive the rotation of the bevel gear A 707. The rotation of the bevel gear A 707 will drive the rotation of the bevel gear B 710. The rotation of the bevel gear B 710 will drive the rotation of the round rod 709. The rotation of the round rod 709 will drive the rotation of the fan blade 711. The rotation of the fan blade 711 will suck air into the protective cover 601, thereby improving the efficiency of air entering the protective cover 601. Since dust will be sucked in with the air during the air suction process of the fan blade 711, the filter screen 714 will filter the air sucked into the protective cover 601 at this time, thereby avoiding the effect of dust entering the protective cover 601 with the air. When the air enters the protective cover 601, it will blow towards the rectangular plate 708. Since the V-shaped plate 713 is fixed on the surface of the rectangular plate 708, the flow direction of the air is shunted, avoiding further improving the air flow effect.

[0035] When the runner 612 rotates, it will drive the cam 86 to rotate. The rotation of the cam 86 will impact the push rod 83. The push rod 83 will slide in the top plate 3 when it is impacted. When the push rod 83 moves, the spring 85 will be compressed. The movement of the push rod 83 will squeeze the rotating plate 82. The rotating plate 82 will rotate on the surface of the top plate 3 when it is squeezed by the push rod 83. When the rotating plate 82 rotates, it will stretch the elastic cloth 88. The rotating plate 82 will gradually rotate towards a vertical angle. At this time, the fallen leaves or impurities on the rotating plate 82 will slide off due to the excessive angle of the rotating plate 82. When the cam 86 is separated from the push rod 83, the push rod 83 will return to its original position by the force of the spring 85 contraction. The rotating plate 82 will rotate and return to its original position by its own weight and the elastic force of the elastic cloth 88 rebounding. The elastic cloth 88 reaches an angle convenient for resetting the rotating plate 82, thereby facilitating covering the gap between the two rotating plates 82 after rotation and preventing impurities from entering the position between the rotating plate 82 and the top plate 3.

[0036] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
