[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] The present invention provides the following technical solutions: a distribution box for construction, comprising: a rainwater collection base 2 with an open top and a hollow interior, support columns 6 installed at the four corners of the bottom wall of the rainwater collection base 2, a distribution box body 4 installed on the top of the four support columns 6, a movable plate 3 is provided inside the rainwater collection base 2 below the distribution box body 4, the movable plate 3 is movably mounted on the four support columns 6 through the opening, and sealing rings are installed on the inner and outer walls of the hole, a lifting mechanism squeezed by collected rainwater is installed between the movable plate 3 and the rainwater collection base 2, two protective plates 5 are symmetrically arranged above the distribution box body 4, a mobile drive mechanism is installed between the two protective plates 5 and the rainwater collection base 2 and the movable plate 3, and a water outlet pipe 1 with a valve is installed on the side wall of the rainwater collection base 2 below the movable plate 3.

[0030] In this embodiment, see the attached Figures 1-3When the distribution box is used on rainy days, rainwater is collected above the movable plate 3 in the rainwater collecting base 2. If the rain is heavy, the amount of rainwater collected gradually increases, and the weight of the rainwater presses the movable plate 3, which moves downward on the lifting mechanism. The movable plate 3 moving downward drives the movable driving mechanism, and the movable driving mechanism drives the two protective plates 5 to move toward each other until the movable plate 3 moves downward to the limit. The two protective plates 5 are closed to protect the distribution box body 4, preventing rainwater from continuously contacting the distribution box body 4 and causing moisture to enter, thereby improving the safety of the distribution box body 4.

[0031] The sizes of the two protective plates 5 are configured according to the size of the distribution box 4 so that the two protective plates 5 can protect the distribution box 4 when closed;

[0032] The rainwater collecting base 2 is larger than the two protective plates 5 so that the rainwater collecting base 2 can collect rainwater;

[0033] After the rain stops, open the valve of the valved outlet pipe 1 to release the rainwater above the movable plate 3 in the rainwater collection base 2, and then reset;

[0034] At the same time, if the distribution box has a sunshade requirement on sunny days, a counterweight block can be added above the movable plate 3 to achieve the sunshade function of closing the two protective plates 5.

[0035] Specifically, the height of the support column 6 is higher than the height of the rainwater collecting base 2 , that is, the horizontal plane of the bottom end of the distribution box 4 is higher than the horizontal plane of the top end of the rainwater collecting base 2 .

[0036] In this embodiment, see the attached Figure 2 If the movable plate 3 moves downward to the limit and cannot move downward any further, the rainwater is directly discharged from the top opening of the rainwater collecting base 2, which can prevent the rainwater from contacting the distribution box 4 and improve the safety of the distribution box 4.

[0037] Specifically, the lifting mechanism includes four lifting columns 101 installed at the four corners of the bottom wall inside the rainwater collecting base 2 and four lifting holes 102 opened at the four corners of the movable plate 3. The four lifting columns 101 are located on the outside of the four support columns 6. The top ends of the four lifting columns 101 extend upward through the four lifting holes 102. The lifting columns 101 are sheathed with connecting springs 103. The two ends of the connecting springs 103 are respectively fixed to the bottom end of the movable plate 3 and the bottom wall inside the rainwater collecting base 2.

[0038] In this embodiment, see the attached Figures 2-3 The lifting mechanism is pressed by the weight of rainwater on the movable plate 3, and the movable plate 3 squeezes the four connecting springs 103 on the four lifting columns 101 to move downward;

[0039] After the rainwater is drained, the four connecting springs 103 are elastically reset, driving the movable plate 3 to rise on the four lifting columns 101, thereby achieving upward movement and reset.

[0040] Specifically, the mobile driving mechanism includes a lifting driving rotating mechanism, a rotating moving mechanism and a linkage mechanism. The lifting driving mechanism is driven to rotate under the squeeze of collected rainwater. The rotating moving mechanism drives the two protective plates 5 to move closer to or away from each other under the rotational force. The linkage mechanism drives the rotating moving mechanism to rotate in a linked manner under the rotational force of the lifting driving mechanism, driving the two protective plates 5 to move closer to or away from each other.

[0041] Specifically, the lifting drive rotation mechanism includes two first racks 203 symmetrically installed on the top of the movable plate 3 and four first mounting plates 204 installed on the inner side wall of the rainwater collecting base 2 at the top of the movable plate 3. The four first mounting plates 204 are symmetrical in pairs. A first driving shaft 201 is arranged between the two first mounting plates 204 installed on the same side wall inside the rainwater collecting base 2. The two ends of the first driving shaft 201 respectively pass through the two first mounting plates 204 and extend to the other side. The first driving shaft 201 is connected to the through section of the first mounting plate 204 through a bearing. A first gear 202 is mounted on the first driving shaft 201 between the two first mounting plates 204, and the first gear 202 is meshed with the first rack 203.

[0042] In this embodiment, see the attached Figure 1 and 4 The lifting drive rotation mechanism is driven by the movable plate 3 moving downward to drive the two first racks 203 to move downward. During the downward movement of the two first racks 203, one of the two first gears 202 is driven to rotate clockwise and the other to rotate counterclockwise, thereby realizing the lifting drive rotation. At this time, the two protective plates 5 move toward each other and close under the driving action of the linkage mechanism and the rotating movement mechanism;

[0043] The movable plate 3 that moves upward and resets drives the two first racks 203 to move upward. During the upward movement of the two first racks 203, the two first gears 202 are driven to rotate one counterclockwise and the other clockwise, realizing the lifting and lowering drive rotation. At this time, the two protective plates 5 move away from each other and open under the driving action of the linkage mechanism and the rotating and moving mechanism.

[0044] Specifically, the rotating and moving mechanism includes four support rods 301 fixedly mounted on the top of the rainwater collecting base 2, two second racks 304 fixedly mounted in the middle of the bottom end of the protective plate 5, and eight mounting seats 307 fixedly mounted at the four corners of the bottom end of the protective plate 5. The four support rods 301 are symmetrical in pairs, and the four support rods 301 are respectively fixedly mounted with second mounting plates 305 on the inner side walls. A second driving shaft 302 is provided between the two second mounting plates 305 mounted on the two support rods 301 on the same side wall of the top of the rainwater collecting base 2. The second driving shaft 302 is provided between the two second mounting plates 305. 02, both ends of which pass through the two second mounting plates 305 and extend to the other side. The second drive shaft 302 is connected to the through section of the second mounting plate 305 through a bearing. A second gear 306 is mounted on the second drive shaft 302 between the two second mounting plates 305. The second gear 306 is meshed with the second rack 304. A mounting block 303 is fixedly mounted on the top of the second mounting plate 305. A hole is opened inside the mounting block 303 and a moving rod 308 is arranged in the hole. Both ends of the moving rod 308 are fixedly mounted on the two mounting seats 307 at corresponding positions.

[0045] In this embodiment, see the attached Figure 1 、 2 , 5 and 6, the rotation and movement mechanism is driven by a linkage mechanism to drive the two second drive shafts 302, one to rotate clockwise and the other to rotate counterclockwise. The two second drive shafts 302 drive the two second gears 306, one to rotate clockwise and the other to rotate counterclockwise. During the rotation of the two second gears 306, they respectively drive the two meshingly connected second racks 304 to move toward each other. The two second racks 304 drive the two protective plates 5 to move toward each other, so as to achieve the movement and closure of the two protective plates 5.

[0046] The linkage mechanism drives the two second drive shafts 302 to rotate one counterclockwise and the other clockwise. The two second drive shafts 302 drive the two second gears 306 to rotate one counterclockwise and the other clockwise. During the rotation of the two second gears 306, the two second racks 304 engaged with each other are driven to move away from each other. The two second racks 304 drive the two protective plates 5 to move away from each other, so as to realize the movement and opening of the two protective plates 5.

[0047] Specifically, the linkage mechanism includes four third gears 401 sleeved on both ends of the first drive shaft 201 and the second drive shaft 302 , and the upper and lower third gears 401 are sleeved with toothed belts 402 for meshing transmission.

[0048] In this embodiment, see the attached Figure 1 、 4And 5, the linkage mechanism is driven by the rotating first drive shaft 201 to drive the two connected third gears 401 to rotate in the same direction, the two connected third gears 401 drive the two meshing toothed belts 402 to rotate in the same direction, the two toothed belts 402 drive the other two meshing third gears 401 to rotate in the same direction, and the other two third gears 401 drive the connected second drive shaft 302 to rotate in the same direction to achieve linkage.
