DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0039] See also Figures 1 to 11 The present invention provides a technical solution: a distribution box, comprising a box body 1, a rain shield 2 is fixedly connected to the surface of the box body 1, a box door 3 is fixedly connected to the surface of the box body 1, a bracket 4 is fixedly connected to the bottom surface of the box body 1, an inner box 5 is fixedly connected to the inside of the box body 1, and a heat dissipation hole 6 is opened on the surface of the box body 1;

[0040] The surface of the rain shield 2 is slidably connected with a wiper 7, four knocking blocks 8 are arranged inside the box body 1, and a baffle 9 is slidably connected to the inner wall of the box body 1;

[0041] It also includes a cleaning component, which is arranged in the box body 1. Through the arrangement of the cleaning component, the wiper 7 can move back and forth in the horizontal direction;

[0042] It also includes a knocking component, which is in transmission connection with the cleaning component. Through the arrangement of the knocking component, the four knocking blocks 8 are axially reciprocated.

[0043] The inner box 5 also includes a lifting component, which is arranged inside the inner box 5. Through the arrangement of the lifting component, the baffle 9 is vertically displaced.

[0044] More specifically, in this embodiment: the distribution box is an outdoor distribution box, and the box door 3 needs to be opened to install the wires, controller and switch in the box body 1, and it can be used after the installation is completed. During use, the bracket 4 can be set to prevent the box body 1 from directly contacting the ground on rainy days to prevent rainwater from penetrating into the distribution box. The heat dissipation holes 6 can help discharge the heat when the inside is used;

[0045] In an outdoor rainy day environment, the wiper 7 can be moved back and forth in the horizontal direction by setting the cleaning component, so as to scrape off the rainwater that may accumulate on the surface of the rain shield 2, thereby preventing the rain shield 2 from being soaked in rainwater for a long time, causing corrosion and rust;

[0046] In this process, the striking component can be driven to operate synchronously. By setting the striking component, the four striking blocks 8 can be moved back and forth axially to knock off the rainwater adhering to the side wall of the box body 1, so as to prevent the moisture generated by the rainwater on the box body 1 from rusting the rain shield and reducing the waterproof performance.

[0047] In this process, the lifting component is driven synchronously. Through the setting of the lifting component, the baffle 9 is displaced vertically, so that the heat dissipation hole 6 can be blocked to prevent the splashing of rainwater and the occurrence of internal leakage damage.

[0048] Embodiment 2, based on the above embodiment:

[0049] See also Figures 2 to 4 , the components in the first embodiment are disclosed as follows, the cleaning component comprises:

[0050] Motor 10, the inner wall of the box body 1 is fixedly connected with a support plate 11, the motor 10 is fixedly connected to the surface of the support plate 11, the output end of the motor 10 is fixedly connected to the inner wall of the box body 1 for fixed-axis rotation, the output end of the motor 10 is fixedly connected to a connecting rod 12, the end of the connecting rod 12 is fixedly connected to a connecting shaft 13, the shaft wall of the connecting shaft 13 is slidably connected with a cross bar 15, the surface of the cross bar 15 is fixedly connected with a U-shaped rod 14, the inner wall of the U-shaped rod 14 is slidably connected to the side wall of the rain shield 2, and the U-shaped rod 14 is fixedly connected to the surface of the wiper 7.

[0051] More specifically, in the present embodiment: when the heavy rain stops, rainwater will accumulate on the top surface of the rain shield 2. At this time, it is necessary to scrape off the rainwater on the surface of the rain shield 2, and the motor 10 can be started. Through the rotation of the output end of the motor 10, the connecting rod 12 is synchronously driven to rotate. Through the rotation of the connecting rod 12, the cross bar 15 is synchronously driven to move back and forth in the horizontal direction. Through the horizontal reciprocating movement of the cross bar 15, the U-shaped rod 14 can be synchronously driven to move back and forth in the horizontal direction. This displacement process is limited by the box body 1. Through the reciprocating movement of the U-shaped rod 14, the wiper 7 moves back and forth in the horizontal direction on the top surface of the rain shield 2, so that the rainwater on the surface of the rain shield 2 can be scraped off, thereby avoiding the situation where the surface of the rain shield is rusted due to the immersion of rainwater, resulting in reduced waterproofness.

[0052] Embodiment 3, based on the above embodiment:

[0053] See also Figures 4 to 9 , the components in the first embodiment are disclosed as follows, the striking component includes:

[0054] A connecting rod 16 is fixedly connected to the side wall of the cross bar 15, and a slide plate 17 is fixedly connected to the end of the connecting rod 16. A sliding opening for displacement of the connecting rod 16 is provided on the top surface of the box body 1, and a supporting plate 18 is fixedly connected to the inner wall of the box body 1. A groove is provided on the surface of the supporting plate 18, and the side wall of the slide plate 17 is slidably connected to the groove wall of the groove. A limiting groove 19 is provided on the bottom surface of the slide plate 17, and a connecting shaft 20 is slidably connected to the groove wall of the limiting groove 19, and a connecting shaft 20 is fixedly connected to the end of the connecting shaft 20. A connecting rod 21 is fixedly connected to the supporting plate 2 The bottom surface of 18 is fixedly connected with two limit blocks 22, a connecting rod 21 is slidably connected to the inner walls of the two limit blocks 22, both ends of the connecting rod 21 are rotatably connected to two push rods 23, the inner wall of the box body 1 is fixedly connected with two straight rods 24, the rod arms of the two straight rods 24 are each provided with a groove 2, the groove walls of the two grooves 2 are slidably connected with two push rods 26, the rod walls of the four push rods 26 are respectively rotatably connected to the rod walls of the four push rods 23, and the ends of the four push rods 26 are respectively fixedly connected to the surfaces of the four knocking blocks 8.

[0055] More specifically, in this embodiment: when it is necessary to knock off the rainwater adhering to the side wall of the box body 1 on a rainy day, for most of the existing distribution boxes, this method can quickly eliminate the water drops adhering to the side wall, and the cross bar 15 in the above process is synchronously driven to move back and forth, and the sliding plate 17 is synchronously driven to move back and forth in the horizontal direction through the transmission of the connecting rod 16. This displacement is limited by the supporting plate 18. During the movement of the sliding plate 17, the limiting groove 19 is synchronously driven to move, and through The displacement of the limiting groove 19 first causes the connecting shaft 20 to slide along the groove wall of the limiting groove 19. Since the connecting shaft 20 is also limited by the connecting rod 21, during the movement of the limiting groove 19, the connecting shaft 20 will be limited by the connecting rod 21 and perform axial reciprocating displacement, that is, the connecting rod 21 is reciprocated along the inner walls of the two limiting blocks 22. Through the axial reciprocating displacement of the connecting rod 21, the four push rods 23 are reciprocated about the connection with the connecting rod 21.

[0056] At this time Figure 8 The direction and state shown in FIG. 2 are described as an example. For the left side structure of the connecting rod 21, the connecting rod 21 is Figure 8When the connecting rod 21 moves upward in the direction shown, the two push rods 23 on the left are synchronously driven to deflect. Through the deflection of the two push rods 23, the upper push rod 23 is away from the box body 1, and the lower push rod 23 is close to the inner wall of the box body 1. When the connecting rod 21 moves downward, the upper push rod 23 is close to the box body 1, and the lower push rod 23 is away from the inner wall of the box body 1. The two push rods 23 on the right side of the connecting rod 21 are consistent with the movement principle on the left side. In this way, during the reciprocating movement of the connecting rod 21, the four push rods 26 and the four knocking blocks 8 are driven, so that the four knocking blocks 8 continuously knock on the inner wall of the box body 1, so that the inner wall of the box body 1 is constantly vibrated, so that the water droplets attached to the surface of the box body 1 can be shaken off, to avoid the long-term attachment of rainwater to cause rust on the box body, resulting in a decrease in the waterproof effect of the box body, and at the same time increase the service life of the distribution box.

[0057] Embodiment 4, based on the above embodiment:

[0058] See also Figure 10 to Figure 11 , the components in the first embodiment are disclosed as follows, the lifting component includes:

[0059] Motor 2 27 is fixedly connected to the inner wall of the inner box 5 , a gear 28 is fixedly connected to the output end of motor 27 , a rack row 29 is fixedly connected to the bottom surface of the baffle 9 , and the teeth of the rack row 29 mesh with the teeth of the gear 28 .

[0060] More specifically, in this embodiment:

[0061] When it is about to rain, the motor 27 can be started, and the gear 28 can be driven to rotate synchronously by the rotation of the motor 27. The rack row 29 can be synchronously displaced upward by the rotation of the gear 28. The baffle 9 can be synchronously driven to move upward by the displacement of the rack row 29. The heat dissipation hole 6 can be shielded by the upward displacement of the baffle 9, so that in a rainy environment, rainwater will not splash into the inner wall of the box body 1 through the heat dissipation hole 6, thereby avoiding the leakage of the internal structure caused by rainwater, and at the same time ensuring the waterproofness of the box body 1;

[0062] It is worth noting that when it is sunny, the motor 27 can be started in the reverse direction to lower the baffle 9, thereby removing the shielding of the heat dissipation hole 6, so that the box body 1 can maintain normal heat dissipation.

[0063] Embodiment 5, based on the above embodiment:

[0064] See also Figure 5 , the components in the first embodiment are supplemented as follows: a handle 30 is connected to the surface of the door 3 for fixed-axis rotation, and the handle 30 is connected to the door via a torsion spring.

[0065] More specifically, in this embodiment, the arrangement of the handle 30 on the surface of the door 3 allows the user to open and close the door 3 better, making it more convenient for the user to use.

[0066] Embodiment 6, based on the above embodiment:

[0067] See also Figure 4 , the components in the first embodiment are supplemented as follows: a sealing strip 31 is provided at the connection between the box body 1 and the box door 3, and the material of the sealing strip 31 is rubber material.

[0068] More specifically, in this embodiment: by providing a sealing strip 31 at the connection between the box body 1 and the box door 3, the box body 1 is more tightly sealed, and the power supply and switch inside the box body 1 are better waterproofed to avoid short circuit leakage caused by rainwater intrusion.

[0069] Embodiment 7, based on the above embodiment:

[0070] See also Figure 1 , the components in the first embodiment are supplemented as follows: a transparent panel 32 is fixedly connected to the surface of the door 3, and the material of the transparent panel 32 is acrylic material.

[0071] More specifically, in this embodiment: by fixing a transparent panel 32 on the surface of the box door 3, it is more convenient to observe whether a short circuit occurs in the internal switch, and it is more convenient for power personnel to use. By setting the transparent panel 32 to an acrylic material, the acrylic material has good transparency, chemical stability and weather resistance, and is more convenient for users to observe.

[0072] Embodiment 8, based on the above embodiment:

[0073] See also Figure 4 and Fig.10 , the components in the first embodiment are supplemented as follows: an activated carbon bag 33 is fixedly connected to the inner wall of the box body 1, and the material of the four knocking blocks 8 are all rubber.

[0074] More specifically, in this embodiment, the activated carbon bag 33 is fixedly connected to the inner wall of the box body 1, so that the infiltrated water vapor can be absorbed to ensure the dryness of the inside of the box body 1.

[0075] Working principle: When the distribution box is used, it is necessary to open the box door 3 to install the wires, controller and switch in the box body 1. After the installation is completed, it can be used. During use, the bracket 4 can be set to prevent the box body 1 from directly contacting the ground on rainy days to prevent rainwater from penetrating into the distribution box. The heat dissipation holes 6 can help discharge the heat when the inside is used;

[0076] Because it is in an outdoor rainy environment, the rainwater accumulated on the surface of the rain shield 2 needs to be swept away to ensure the waterproofness of the distribution box. It is necessary to start the motor 10. Through the rotation of the motor 10, the connecting rod 12 can be rotated synchronously. Through the rotation of the connecting rod 12, the cross bar 15 is synchronously moved back and forth in the horizontal direction, and the U-shaped rod 14 is moved back and forth in the horizontal direction. Through the reciprocating movement of the U-shaped rod 14, the wiper 7 is synchronously driven to move back and forth in the horizontal direction on the surface of the rain shield 2, so that the accumulated water on the surface of the rain shield 2 is scraped off, so as to avoid the rain shield being soaked and rusted by the rain, resulting in reduced waterproofness.

[0077] When it stops raining, in the process of sweeping off the rainwater accumulated on the surface of the rain shield 2, it is also necessary to clean the rainwater attached to the side wall of the distribution box. The connecting rod 16 is moved back and forth, which can drive the slide plate 17 to move back and forth in the horizontal direction synchronously. Due to the setting of the limit groove 19 and the two limit blocks 22, the reciprocating movement of the slide plate 17 can drive the connecting rod 21 to move back and forth axially, and synchronously drive the four push rods 23 to deflect back and forth with the connection with the connecting rod 21 as the axis, so that the four push rods 26 move back and forth in the horizontal direction. Through the reciprocating movement of the four push rods 26, the four knocking blocks 8 are synchronously driven to knock on the inner wall of the box body 1, so that the water droplets attached to the surface of the box body 1 can be knocked, so as to avoid the long-term corrosion of water droplets causing rust on the box body, resulting in a decrease in the waterproof effect of the box body, and at the same time increase the service life of the distribution box;

[0078] Before it is about to rain, the motor 27 can be started synchronously, and the gear 28 can be rotated synchronously through the rotation of the motor 27. The rack row 29 is synchronously driven to move upward through the rotation of the gear 28. The baffle 9 is synchronously moved upward through the displacement of the rack row 29. The heat dissipation hole 6 can be blocked through the upward displacement of the baffle 9, so that in a rainy environment, rainwater will not splash into the inner wall of the box body 1 through the heat dissipation hole 6, thereby avoiding the occurrence of leakage of the internal structure caused by rainwater, and at the same time, the waterproofness of the box body 1 can be ensured.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
