Embodiment
Referring to figs. 1 through Fig. 4, the utility model heat radiation cable branch box embodiment is described further.
See Fig. 1 to 4, a kind of heat radiation cable branch box, it comprises casing 1 and chamber door 2, described casing 1 is provided with heat abstractor 21 on chamber door 2 both sides box wall, described heat abstractor 21 comprises blade 212 and support portion 216, described support portion 216 is fixed on above described blade 212, the middle part of described blade 212 is equipped with the rotating shaft 219 be fixedly connected with casing 1, one end of described blade 212 is fixedly connected with out leaf stay cord 214 and Guan Ye stay cord 213, pass leaf stay cord 213 is fixedly connected with by one end, ground and stores rain chamber 211, the described rain chamber 211 that stores is provided with opening, the described rain chamber 211 that stores just is provided with through hole 2111 to opening surface, described leaf stay cord 213 of opening is walked around support portion 216 away from one end, ground and is fixedly connected with and draws body 215, described rotating shaft 219 keeps away leaf stay cord 214 side and is provided with guide vane end stop 218, described draw body 215 weight be greater than described in store rain chamber 211 weight, during described storage chamber 211 full water weight be greater than described in weight when drawing body 215 full water.
See Fig. 1, when weather is fine, body 215 self gravitation is drawn to be greater than the gravity storing rain chamber 211, body 215 is drawn to pull out leaf stay cord 214, thus pull on blade 212 and turn over, heat abstractor 21 is opened, now can to cable branch box ventilation and heat, when weather begins to rain, rainwater can drip and completely store rain chamber 211, the gravity now storing rain chamber 211 and rainwater is greater than and draws body 215 gravity, thus pull pass leaf stay cord 213, closing leaf stay cord 213 pulls blade to turn over for 212 times, heat abstractor 21 is closed, now casing 1 can waterproof, after rain or when rainfall is less, the rainwater stored in rain chamber 211 can from through hole 2111 light, draw body 215 gravity to be again greater than and store rain chamber 211 gravity, heat abstractor 21 reopens.
See Fig. 2, open leaf stay cord 214 by fixed pulley 217 in support portion 216, then be fixedly connected with and draw body 215, fixed pulley 217 can reduce to draw body 215 to pull out the friction produced in leaf stay cord 214 process, improve and pull efficiency, extend the useful life of opening leaf stay cord 214, pass leaf stay cord 213 is fixedly connected with and stores rain chamber 211, open leaf stay cord 214 and draw being fixedly connected with of body 215, close leaf stay cord 213 and store being fixedly connected with of rain chamber 211 chain can be adopted to be connected, preventing other people from appropriating public property for personal use and store rain chamber 211 or draw body 215 to cause heat abstractor 21 cisco unity malfunction.
See Fig. 3, storing through hole 2111 below rain chamber 211 and can arrange multiple, determining that a certain rainfall carrys out opening and closing heat abstractor 21 by changing the quantity arranging through hole 2111.
See Fig. 4, rotating shaft 219 is provided with in the middle part of blade 212, rotating shaft 219 is fixedly connected with casing 1, blade 212 and rotating shaft 219 form a lever, the pulling force opened between leaf stay cord 214 and Guan Ye stay cord 213 connected by two ends carries out the switch of blade 212, when the setting of guide vane end stop 218 can make out leaf stay cord 214 pull blade 212 to open, blade 212 can be fixed.
Consider the design feature of cable branch box body 1, casing 1 and chamber door 2 can adopt metal material panel beating to be made, consider that blade 212 weight splits the impact of leaf stay cord 214 and Guan Ye stay cord 213, blade 212 can be made with aluminum material, stay cord intensity and the higher material of toughness are made, draw body 215 can to make with the metal with constant weight, weight is greater than weight when storing rain chamber 211 cavity state, water is full of or after filling a part of water, quality can be greater than draws body 215 weight when storing in rain chamber 211.
