DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0027] Embodiment 1: An outdoor low-voltage distribution box with protection function, referring to Figure 1-Figure 6 , including a distribution cabinet 1, a fence 11, a base 12, a protective mechanism 2 and an isolation mechanism 3. The distribution cabinet 1 is installed in the middle of the top of the base 12, and the fence 11 is installed on the top of the base 12. The protective mechanism 2 is provided on the upper part of the fence 11. The protective mechanism 2 is used to block the side of the distribution cabinet 1. The isolation mechanism 3 is provided on the protective mechanism 2. The isolation mechanism 3 is used to block the upper side of the distribution cabinet 1.

[0028] Reference Figure 3-Figure 5 The protection mechanism 2 includes a first baffle 21, a second baffle 22, a first slide bar 23, a first tension spring 24, a first block 25, a first telescopic assembly 26 and a first connecting plate 27. Four first slide bars 23 are welded on the upper part of the fence 11. The first baffle 21 is slidably connected between the four first slide bars 23. Four first tension springs 24 are connected between the lower part of the first baffle 21 and the fence 11. The first tension spring 24 is sleeved on the first slide bar 23. Four second baffles 22 are installed on the upper part of the fence 11. The first baffle 21 and The second baffle 22 plays a blocking role, and the first baffle 21 is sleeved on the four second baffles 22. Two first connecting plates 27 are welded in the middle of the left and right sides of the fence 11, and two first telescopic components 26 are installed on the first connecting plates 27. The first telescopic components 26 are connected by telescopic rods and springs. The inner sides of two adjacent first telescopic components 26 are connected with first clamping blocks 25. The first clamping blocks 25 are triangular. The left and right sides of the lower part of the first baffle 21 are symmetrically provided with clamping grooves, and the first clamping blocks 25 are clamped in the clamping grooves of the first baffle 21.

[0029] Reference Figure 6 The isolation mechanism 3 includes a third baffle plate 31, a torsion spring 32 and a clamping rod 33. Four third baffle plates 31 are rotatably connected to the top of the first baffle plate 21. The third baffle plates 31 play a blocking role. Two torsion springs 32 are connected between the third baffle plates 31 and the first baffle plates 21. Four clamping rods 33 are installed on the inner side of the fence 11, and the clamping rods 33 clamp the third baffle plates 31.

[0030] In the initial state, the first tension spring 24 is stretched and the torsion spring 32 is deformed. When someone climbs the fence 11, the first baffle plate 21 is pressed downward, and the first baffle plate 21 pushes the first clamping block 25 to move outward, and the first telescopic component 26 contracts. When the first baffle plate 21 is relaxed, the first baffle plate 21 is driven to move upward and rise to block under the action of the first tension spring 24 returning to its original position. When the first baffle plate 21 is separated from the first clamping block 25, the first telescopic component 26 returns to its original position and drives the first clamping block 25 to move inward and return to its original position. When the first baffle plate 21 moves upward, the first baffle plate 21 drives the third baffle plate 31 and the torsion spring 32 to move upward, so that the third baffle plate 31 is separated from the clamping rod 33, and then drives the third baffle plate 31 to move upward under the action of the torsion spring 32 returning to its original position. The plate 31 rotates upward to block the top of the distribution cabinet 1, so as to prevent people from climbing into the fence 11 and damaging the distribution cabinet 1. The third baffle plate 31 is manually rotated downward, the torsion spring 32 is deformed, and then the first baffle plate 21 is pressed downward. The first tension spring 24 is stretched, and the first baffle plate 21 drives the third baffle plate 31 to move downward, so that the third baffle plate 31 is blocked on the upper part of the clamping rod 33. At the same time, the first baffle plate 21 contacts the first clamping block 25, and the first baffle plate 21 pushes the first clamping block 25 to move outward, and the first telescopic component 26 contracts. When the slot of the first baffle plate 21 corresponds to the first clamping block 25, the first telescopic component 26 is reset to drive the first clamping block 25 to move inward and be clamped into the slot of the first baffle plate 21, thereby limiting the first baffle plate 21.

[0031] Example 2: Based on Example 1, refer to Figure 1 , Figure 7 and Figure 8, also includes a closing mechanism 4, the closing mechanism 4 includes a fifth baffle 41, a second slide bar 42, a pressure spring 43, a second clamping block 44, a second telescopic component 45 and a second connecting plate 46, two second slide bars 42 are welded to the lower part of the left and right sides of the power distribution cabinet 1, and the fifth baffle 41 is slidably connected between the two second slide bars 42 on the left and right sides, and the second slide bars 42 are sleeved with pressure springs 43, and the two ends of the pressure spring 43 are respectively connected to the second slide bar 42 and the fifth baffle 41, and the lower part of the left and right sides of the power distribution cabinet 1 is welded with second connecting plates 46, and two second telescopic components 45 are connected to the second connecting plates 46, and the second telescopic components 45 are connected by telescopic rods and springs, and second clamping blocks 44 are installed between the inner sides of the two second telescopic components 45 on the left and right sides. The second clamping blocks 44 are triangular, and clamping holes are opened in the middle and lower parts of the fifth baffle 41.

[0032] When it rains, the fifth baffle 41 is manually moved downward, and the pressure spring 43 is compressed, so that the fifth baffle 41 blocks the heat dissipation hole of the distribution cabinet 1, thereby preventing rainwater from penetrating into the distribution cabinet 1 through the heat dissipation hole of the distribution cabinet 1 and causing damage to the distribution cabinet 1. When the fifth baffle 41 contacts the second clamping block 44, the first baffle 21 pushes the second clamping block 44 to move outward, and the second telescopic component 45 contracts. When the clamping hole of the fifth baffle 41 corresponds to the second clamping block 44, the second clamping block 44 is driven to move outward under the action of the second telescopic component 45 being reset. The fifth baffle 41 is moved inwardly and clamped into the clamping hole of the fifth baffle 41, thereby limiting the fifth baffle 41. The fifth baffle 41 is manually lifted, and the fifth baffle 41 pushes the second clamping block 44 to move outward and disengage from the clamping hole of the fifth baffle 41. The second telescopic component 45 contracts, and then the fifth baffle 41 is driven to move upward and reset under the action of the pressure spring 43 to no longer block the heat dissipation hole of the distribution cabinet 1. When the fifth baffle 41 is separated from the second clamping block 44, the second telescopic component 45 is driven to move inward and reset under the action of the second telescopic component 45.

The mesh plate 52 is used to collect and block garbage. The rotating plate 53 is installed on the upper part of the connecting rod 51, and the rotating plate 53 is located on the upper side of the mesh plate 52.

[0034] When the third baffle plate 31 rotates upward, the third baffle plate 31 and the mesh plate 52 cooperate to block the top of the distribution cabinet 1, which not only prevents climbing, but also prevents garbage from floating into the fence 11. When the wind blows, the rotating plate 53 will rotate automatically following the direction of the wind, thereby driving the mesh plate 52 to rotate for adjustment. When the garbage floats with the wind, the garbage is collected by the mesh plate 52, which not only prevents the garbage from entering the fence 11, but also facilitates garbage cleaning.

[0036] Pressing the switch 62 to start the condensation plate 61 can cool the power distribution cabinet 1, thereby protecting the power distribution cabinet 1 and preventing the power distribution cabinet 1 from being overheated and reducing its service life. When cooling is not required, pressing the switch 62 to turn off the condensation plate 61 can be sufficient.

The third telescopic components 75 are connected by telescopic rods and springs, and the inner sides of the third telescopic components 75 are connected to third clamping blocks 74, and the third clamping blocks 74 are triangular. Through holes are opened at the front of the left and right sides of the sealing plate 71.

[0038] The cabinet door of the distribution cabinet 1 is reinforced by the sealing plate 71 to prevent the distribution cabinet 1 from being easily opened. When the distribution cabinet 1 needs to be opened, the sealing plate 71 is manually pulled forward to separate from the distribution cabinet 1, and the second tension spring 73 is stretched. When the sealing plate 71 contacts the third clamping block 74, the third clamping block 74 is pushed to move outward, and the third telescopic component 75 is compressed. When the through hole of the sealing plate 71 corresponds to the third clamping block 74, the third clamping block 74 is driven to move inward under the action of the reset of the third telescopic component 75. The sealing plate 71 is inserted into the through hole of the sealing plate 71, thereby limiting the sealing plate 71 and opening the distribution cabinet 1. After closing the distribution cabinet 1, the sealing plate 71 is manually pushed backward, and the sealing plate 71 squeezes the third clamping block 74 outward, so that the third clamping block 74 is separated from the through hole of the sealing plate 71, and then the sealing plate 71 is driven to move backward and reset under the action of the second tension spring 73. The sealing plate 71 is separated from the third clamping block 74, and then the third telescopic assembly 75 is driven to move inward and reset under the action of the third telescopic assembly 75.
