Abstract
The disclosed underground comb channel includes working well, well cover, and comb group. Being composed of multiple underground combs, the comb group is connected to the well. Being connected to outside, a piece of air inlet pipe and a piece of air outlet pipe are fixed in the working well. Features are: simple structure, convenience of construction, and maintenance, no power, no noise, and no pollution, low running cost, well timed adjusting temperature automatically, no need of manual monitoring and managing, and good cooling effect. The invention is widely applicable to build or reconstruct underground comb channel for city distribution network.
Description
Technical field:
The present invention relates to a kind of underground comb passage, relate in particular to a kind of underground cable rake manifold passage that is used for urban power distribution network.
Background technology:
At present, in the transformation and construction in city, universal demand adopts the put cable underground operation of the mode of underground comb passage with electrical network.Traditional underground comb passage mainly is to be made of the active well and the well lid that are embedded in the formed comb group of underground many combs below 0.5～0.7 meter, connect each section comb group; For waterproof, generally all require around comb, to coat, and adopt double-deck well lid, so entirely descend the comb passage just to form the structure of totally-enclosed with concrete.In the environment of this totally-enclosed, the heat that cable produced is not easy in time to loose to release, and causes the temperature in the comb passage to raise gradually, thereby causes the ampacity of cable to reduce gradually, finally directly influences power supply quality and power supply safety.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the present invention aim to provide a kind of simple in structure, easy to maintenance, need not manage, can lower the temperature automatically and ventilating temperature-reducing type urban distribution network underground conduit channel safe and reliable to operation.
To achieve these goals, the present invention by the following technical solutions: it comprises active well, well lid and the comb group of being formed and being communicated with this well by many underground combs; An air inlet pipe and blast pipe that is in communication with the outside arranged at the active well internal fixation.
The borehole wall that one end of air inlet pipe is erected in the active well, the other end passes active well stretches out to the external world, and the mouth of pipe upper limb of the underground comb of end one deck of the outlet of air inlet pipe and described comb group is concordant; One end of blast pipe be horizontally fixed in the active well and be close to the back side of well lid, the borehole wall that the other end passes active well stretches out to the external world; The inlet of air inlet pipe and the outlet of blast pipe are downward-sloping; The inlet of air inlet pipe and the exit of blast pipe are provided with stainless steel cloth.
The present invention is owing to made full use of the principle of hot and cold cross-ventilation exchange, and in active well, inject the hot-air that cold air and blast pipe will accumulate in the power distribution network underground cable rake manifold passage and outwards discharge, thereby reach the purpose of effective reduction comb channel temperature by being installed in a air inlet pipe in the active well.Compared with the prior art, the present invention has the following advantages:
1. unpowered, noiselessness, pollution-free, operating cost is low;
2. simple in structure, construction and easy to maintenance;
3. regulate temperature in good time automatically, do not need the personal monitoring to manage;
4. good cooling effect, show according to actual measured results: well temperature is only high about 3 ℃ than ambient temperature, stage casing temperature in the comb between two wells is only high about 6 ℃ than ambient temperature, and the ambient temperature that satisfies the cable operation fully requires (≤45 ℃).
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the B-B cutaway view among Fig. 1.
Among the figure: well lid 1 air inlet pipe 2 blast pipes 3 active wells 4 underground combs 5
Embodiment:
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～3, two or more comb groups are passed the borehole wall from two or more directions and are stretched into the active well 4, and above-mentioned each comb group is interconnected by active well 4; Described comb group is made of many underground combs 5.Airtight active well 4 well head places are provided with well lid 1, and an air inlet pipe 2 and blast pipe 3 that is in communication with the outside arranged at active well 4 internal fixation.In order to improve the efficient of heat exchange, the borehole wall that an end of air inlet pipe 2 is erected in the active well 4, the other end passes active well 4 stretches out to the external world; One end of blast pipe 3 is horizontally fixed in the active well 4 and is close to as far as possible the back side of well lid 1, and the borehole wall that extreme higher position, the other end that is in hot-air in the well with the inlet that guarantees blast pipe 3 passes active well 4 stretches out to the external world.The outlet of air inlet pipe 2 is flooded in infiltration in the active well 4, and the outlet of air inlet pipe 2 is concordant with the mouth of pipe upper limb of the underground comb 5 of end one deck of described comb group.Enter in the active well 4 for fear of rainwater, the outlet of the inlet of air inlet pipe 2 and blast pipe 3 should be downward-sloping; Enter in the active well 4 for fear of foreign matter, also be provided with stainless steel cloth at the inlet of air inlet pipe 2 and the exit of blast pipe 3.For attractive in appearance and do not influence traffic, near the greenbelt under the section of stretching out of air inlet pipe 2 and blast pipe 3 should be hidden in the comb passage.
Be one group of contrast test data that the present invention and traditional underground comb passage are done under the essentially identical situation of test condition below:
Table 1:
Table 2:
Wherein, table 1 is the observed temperature of 1～No. 5 active well of the underground comb passage of the present invention; Table 2 is that the inlet and outlet duct occlusion in 1～No. 5 active well of the present invention is formed the observed temperature that descends the comb passage traditionally later on, and be 15 days off-period.From above-mentioned two groups of correction datas as can be seen, the temperature in the underground comb passage of the present invention has obtained significantly reducing, and can satisfy cable fully and move desired ambient temperature index (≤45 ℃).
