Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: referring to fig. 1-4, a partition frame 2 is arranged on the inner side of the shell 1; the partition frame 2 is provided with a vent hole 101; a waterproof breathable film 102 is arranged on one side of the partition frame 2 close to the shell 1; the top end of the partition frame 2 is provided with a first fixed platform 201; the top of the shell 1 is provided with a rain hat 3; the two sides of the rain hat 3 are provided with the ventilating separation net 202; the rain hat 3 is connected with the shell 1 through a breathable separation net 202; a second fixed platform 203 is arranged on one side of the rain hat 3 close to the partition frame 2; an exhaust rod 4 is arranged between the first fixing table 201 and the second fixing table 203; a spiral plate 204 is arranged on one side of the exhaust rod 4 close to the partition frame 2; a wind cap 205 in the positive and negative directions is arranged on one side of the exhaust rod 4 close to the rain cap 3; the bottom of the shell 1 is provided with an inclined plane groove 103; an air inlet pipe 5 is arranged on one side of the inclined groove 103 close to the shell 1; the inner wall of the air inlet pipe 5 is provided with a limiting groove 104; a water level column 6 is arranged in the air inlet pipe 5; a floating seal cover 7 is arranged on the water level column 6; the air inlet pipe 5 is connected with the floating seal cover 7 through a water level column 6; an air inlet 105 is arranged on one side of the air inlet pipe 5; one side of the shell 1 is provided with a sealing door 8; a sealing strip 106 is arranged on one side of the closing door 8 close to the partition frame 2; the bottom of the partition frame 2 is provided with a wire inlet pipe 9; the partition frame 2 is communicated with the shell 1 through a wire inlet pipe 9; a plugging air bag 10 is arranged in the inlet pipe 9.
When the ring main unit protection device is used, the first step is combined with the step shown in fig. 1, when the ring main unit protection device is used, a user often causes water to enter the ring main unit due to excessive rainwater in an area, the ring main unit fails to leak electricity, and serious potential safety hazards are brought to the user.
Step two, as shown in fig. 1-4, because the ring main unit generates heat during normal operation, air enters the inside of the housing 1 through the air inlet 105, the air enters the inside of the partition frame 2 through the waterproof breathable film 102 and the air vent 101 for cooling, and at the same time, the air exhaust rod 4 at the top of the partition frame 2 touches the wind cap 205 to drive the air exhaust rod 4 and the spiral plate 204 to rotate through external wind power, at this time, the air with heat rapidly rises through the waterproof breathable film 102 through the rotation of the spiral plate 204 and rapidly blows away the air with heat through external wind power to achieve the heat dissipation function, because most of the ring main units are placed beside the street, when a sprinkler passes through, water inadvertently enters the inside of the housing 1 through the breathable partition net 202, at this time, the waterproof breathable film blocks the entering water outside the partition frame 2, the water blocked outside the partition frame 2 enters the inclined plane groove 103, and the slope of the inclined plane groove 103 is rapidly discharged through the air inlet, when meeting rainwater weather, if can not in time the drainage, along with the water level constantly risees, cursory closing cap 7 at this moment also can rise along with the water level, cursory closing cap 7 will block on spacing groove 104 when the water level is higher than inlet port 105, makes intake pipe 5 be in the state of sealing up completely to prevent that the rainwater from flowing backward, cursory closing cap 7 will get back to the normal position and reopen intake pipe 5 when the rainwater moves back.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
