[0017] In this embodiment: the support base 1 is used to support and connect various components, so that through the cooperation of other components, it plays a role in protecting the distribution cabinet, so that irrelevant personnel cannot directly contact the distribution cabinet, and the shielding top plate 2 provided above the support base 1 is used to protect the top of the distribution cabinet, so that when it rains, rainwater will not directly contact the cabinet body, avoiding corrosion of the cabinet body by rainwater, etc. The protective blocking frame 11 fixed between the support base 1 and the shielding top plate 2 is used to protect the distribution cabinet, so that personnel cannot enter the protective blocking frame 11 The shielding top plate 2 supports the storage bin 3 so that the storage bin 3 can store rainwater. The water storage cavity 31 inside the storage bin 3 is used to make space for storing rainwater, so that the rainwater can be stored inside the storage bin 3 to avoid direct contact between the rainwater and the outside world, thereby reducing the risk of rainwater leakage. The evaporation effect of rainwater allows rainwater to be stored in the storage bin 3 for a longer period of time. The storage bin 3 is slidably connected with a linkage plate 32, which is used to block the drain port of the storage bin 3, so that when no fire occurs, the water source in the water storage chamber 31 will not be discharged from the storage bin 3. The positioning frame 4 fixed at the bottom of the storage bin 3 is used to support the traction rope 41, which is fixedly connected to the linkage plate 32. Since the traction rope 41 is located below the shielding top plate 2, and the power distribution cabinet is also installed below the shielding top plate 2, when the power distribution cabinet When a fire occurs, the burning open flame will come into contact with the traction rope 41, and the traction rope 41 is made of a material with a low ignition point, so that when the open flame comes into contact with the traction rope 41, the traction rope 41 will melt. After melting, the traction rope 41 will cancel the limit on the interlocking disk 32. At this time, the interlocking disk 32 located inside the water storage chamber 31 will move upward due to the buoyancy of the water source, so that the interlocking disk 32 will cancel the blockage of the drain outlet at the bottom of the storage bin 3, and then the water source located inside the water storage chamber 31 will be discharged from the storage bin 3, thereby achieving the purpose of curbing and weakening the fire.

[0018] A plurality of mounting seats 12 are fixedly connected to the outside of the support base 1, and an open door 13 is rotatably connected to one side of the support base 1; the mounting seats 12 fixed on the outside of the support base 1 are used to extend the support base 1, and a threaded mounting groove is provided inside the mounting seats 12, so that the staff can fix the mounting seats 12 in a suitable position by bolts, etc., and then complete the installation of the support base 1; the open door 13 rotatable on one side of the support base 1 is used to open or block the internal space of the support base 1, so that the staff can enter the interior of the support base 1 by rotating the open door 13, so as to operate the distribution cabinet, and the open door 13 is connected by hinges or hinges, so that the open door 13 can rotate relative to the support base 1.

[0019] A water inlet 22 is provided inside the shielding top plate 2, and the water collecting pan 21 is connected to the water storage chamber 31 through the water inlet 22; the water inlet 22 provided inside the shielding top plate 2 is used to introduce the water source stored inside the water collecting pan 21 into the water storage chamber 31, and the water collecting pan 21 is connected to the water storage chamber 31 through the water inlet 22, so that when rainwater is collected by the water collecting pan 21, rainwater inside the water collecting pan 21 can enter the water storage chamber 31 through the water inlet 22, so that when a fire occurs, the fire can be contained by the rainwater.

[0020] A water inlet 33 is provided at the top of the storage bin 3, and the position of the water inlet 33 corresponds to the water guide port 22. A blocking plate 34 is slidably connected inside the storage bin 3, and a guide block 35 is fixedly connected to the inner wall of the top of the storage bin 3; the water inlet 33 at the top of the storage bin 3 is used to make room for the water source guided by the water guide port 22 to enter the water storage chamber 31, so that the water source can be introduced into the water storage chamber 31 for storage, and the blocking plate 34 sliding inside the storage bin 3 is used to block the water inlet 33, so that when the water source liquid level in the water storage chamber 31 is As it gradually rises, rainwater will contact the blocking plate 34 and drive the blocking plate 34 to move vertically through buoyancy, thereby completing the blocking of the water inlet 33, so that the rainwater inside the water storage chamber 31 will not come into contact with the outside air, thereby achieving the purpose of increasing the storage time of rainwater in the water storage chamber 31. The guide block 35 fixed on the inner wall of the top of the storage bin 3 is used to guide the sliding of the blocking plate 34, so that the blocking plate 34 will not have unnecessary displacement during the sliding process, thereby ensuring that the blocking plate 34 can stably complete the blocking work of the water inlet 33.

[0021] A diffusion plate 42 is fixedly connected to the bottom end of the positioning frame 4, and the diffusion plate 42 corresponds to the center position of the shielding top plate 2; the diffusion plate 42 fixed at the bottom end of the positioning frame 4 is used to guide the water source discharged from the inside of the storage bin 3. The bottom diameter of the diffusion plate 42 is larger than the top, and the diffusion plate 42 is located at the center position of the shielding top plate 2. The drain outlet of the storage bin 3 is also opened at the bottom center position, so that when rainwater inside the storage bin 3 is discharged, it can contact the diffusion plate 42 and diffuse toward the surroundings under the guidance of the diffusion plate 42, thereby increasing the contact opportunity between rainwater and open flames, and thereby the rainwater can play the purpose of curbing and weakening the fire.

[0022] The working principle and use process of the utility model: when the staff installs the distribution cabinet outdoors, they can first place the support base 1 on the outside of the distribution cabinet, and then fix the mounting base 12 by means of bolts or the like, so that the support base 1 can be fixed to the outside of the distribution cabinet. At this time, the protective barrier frame 11 will protect the distribution cabinet to prevent irrelevant personnel from contacting the distribution cabinet, and the shielding top plate 2 will be located above the distribution cabinet. The shielding top plate 2 will shield and protect the distribution cabinet on rainy days to prevent rainwater from directly contacting the distribution cabinet body, and the rainwater will enter the water collection tray 21 and enter the water storage chamber 31 through the water guide port 22 for collection. When the liquid level of rainwater in the water storage chamber 31 gradually rises, it will contact the bottom end of the blocking tray 34. The buoyancy will drive the blocking plate 34 to move vertically upward, and the blocking plate 34 will block the water inlet 33, so that the rainwater inside the water storage chamber 31 will not contact the outside air, thereby increasing the storage time of the rainwater. When a fire occurs in the distribution cabinet, the open flame generated by the combustion will contact the traction rope 41, and the traction rope 41 will melt when burning, so that the traction rope 41 cancels the limit on the interlocking plate 32. At this time, the interlocking plate 32 will move vertically upward under the action of buoyancy, so that the drain port opened at the bottom of the storage bin 3 is exposed. At this time, the rainwater inside the water storage chamber 31 will be discharged from the storage bin 3, and the discharged rainwater will contact the diffusion plate 42 and be guided by the diffusion plate 42, so that the rainwater will flow toward the outside of the diffusion plate 42, thereby achieving the purpose of curbing and weakening the fire.
