Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A manhole for anti-extreme misery, comprises well seat 200, pit shaft 100, inlet pipe 300 and goes out pipe 400; Described pit shaft 100, inlet pipe 300 and go out pipe 400 and be intersected in well seat 200; Described pit shaft 100 is erect and is arranged; Described inlet pipe 300 and go out pipe 400 concentric and arrange.
Described pit shaft 100 comprises the first cylindrical drum 110, first frustum cone cylinder 120 and the second cylindrical drum 130.First frustum cone cylinder 120 upper end connects the first cylindrical drum 110, and lower end connects the second cylindrical drum 130.
Described first cylindrical drum 110 inwall bottom is provided with the snap ring 112 of depression; Snap ring 112 place is embedded with burner 113; Described burner 113 comprises horizontally disposed combustion ring 113a and erects the combustion cover 113b arranged; Described combustion ring 113a is the circular of central opening; The central opening diameter of combustion ring 113a is less than the minimum diameter of the first cylindrical drum 110, more has the impact utilizing burner 113 to receive external environment condition, increases the trigger sensitive of burner 113.Described combustion cover 113b is the cylinder of hollow; Combustion cover 113b top is connected to the excircle of combustion ring 113a; Described combustion cover 113b lateral wall contacts mutually with snap ring 112.At edge, combustion cover 113b is mutually vertical with combustion ring 113a, is more conducive to the installation location of burner 113.Meanwhile, combustion cover 113b is that combustion ring 113a provides enough holding powers, and combustion ring 113a vacates more region contact external environment condition.Described combustion cover 113b bottom touches mutually with upper protector 121, shortens the distance of burner 113 and upper protector 121, after burner 113 triggers, can have more delivered heat to upper protector 121.
Described first frustum cone cylinder 120 is in inverted round table-like, and described first frustum cone cylinder 120 inwall card touches upper protector 121; Described upper protector 121 comprises horizontally disposed upper retaining ring 121a and erects the upper jacket 121b arranged; Described upper retaining ring 121a is the circular of central opening; The central opening diameter of upper retaining ring 121a is identical with the internal diameter of the second cylindrical drum 130.The excircle of described upper retaining ring 121a contacts mutually with the inwall of the first frustum cone cylinder 120; Described upper jacket 121b is the cylinder of hollow; Described upper jacket 121b top is connected to the inner periphery of retaining ring 121a; The bottom surface in the first frustum cone cylinder 120 is touched in described upper jacket 121b bottom.As preferably, the outer wall vertical of described upper jacket 121b is extended upper bracket 121c; The outer end of described upper bracket 121c contacts the inwall in the first frustum cone cylinder 120.
The inwall of upper protector 121 is identical with the internal diameter of the second cylindrical drum 130, accomplishes both laminating transition.The design that first frustum cone cylinder 120 is wide at the top and narrow at the bottom, makes the first frustum cone cylinder 120 can hold the upper protector 121 of more materials, ensure that protector 121 on triggering can the passage of adequate closure second cylindrical drum 130.Upper protector 121 thinner thickness everywhere, and have more surface area, while the intensity that protector 121 is enough on guaranteeing, ensure that the abundant sensitivity of protector 121.
Second cylindrical drum 130 upper end and the first frustum cone cylinder 120 grafting, the junction of the second cylindrical drum 130 and the first frustum cone cylinder 120 arranges sealing ring.Second cylindrical drum 130 lower end and well seat 200 grafting, arrange sealing ring between the second cylindrical drum 130 and well seat 200.Because the north is different with southern well depth, the second cylindrical drum 130 is set so that regulation depth.
Described inlet pipe 300 and to go out between pipe 400 erection and have intervalve 500.Described intervalve 500 one end is provided with bulge loop 501, sheathed joint ring 502 inside bulge loop 501, and intervalve 500 other end outboard shafts is to being evenly equipped with card article 503; Described inlet pipe 300 inwall is provided with the sliding tray adapted with bulge loop 501; Described go out pipe 400 inwall be axially evenly equipped with recessed bar; Described card article 503 is inserted in recessed bar.
Intervalve 500 has been communicated with inlet pipe 300 and has gone out pipe 400, and the cable in inlet pipe 300 directly can enter out pipe 400 by intervalve 500.The cable simultaneously entered from pit shaft 100 enters from the gap between card article 503, fits in out the inwall of pipe 400.Communication cable, through different passages, is conducive to the classification of communication cable, ensure that the neat erection of cable, avoid communication cable to cause mutual extrusion abrasion because of concentrations.
Described burner 113 is made up of combustible material.
The design of burner 113, during breaking out of fire, burner 113 takes the lead in burning, and its heat produced triggers upper protector 121 makes it expand, thus the upper port of closed pit shaft 100 more early, cut off the interior or exterior space of manhole, improve the flame retardant effect of this manhole.
The sidewall of described well seat 200 offers drain hole 203; Described drain hole 203 is equidistantly arranged around Jing Zuo 200 center; Described well seat 200 outer wall is arranged with draining ring 204; Described draining ring 204 and well seat 200 are enclosed to form out drain chamber 205; Described drain hole 203 is connected with drain chamber 205; Described draining ring 204 is connected with gutter 206.
The water gathered in manhole, enters drain chamber 205 by drain hole 203, is finally discharged by gutter 206.The design of multiple drain hole 203, adds through-current capability, and relative to offering a large hole, this structure reduces stress and concentrates, and ensure that the intensity of well seat 200 sidewall, and the better ideal of bottom discharge effect.Draining ring 204 plays the effect assembling drain hole 203 draining, connects the design of a pipeline relative to each drain hole 203, and the processing of this structure is simpler, and material is more saved.
Described well seat 200 erection has the station bar 201 of level; The height of described station bar 201 is lower than inlet pipe 300 and go out pipe 400, and higher than drain hole 203; The bottom of described station bar 201 has been sticked end protector 202; Protector of the described end 202 is rectangular for what have expanded graphite to make.Bar 201 of standing plays the effect of support works personnel operation.End protector 202 on triggering, expands downwards, has completely cut off drainage system, avoids smog to discharge from drainage system.
As preferably, described pit shaft 100 upper end is covered with and imports plate 111, and the center importing plate 111 is provided with circular Lead-In Area, and the diameter of Lead-In Area is not more than the internal diameter of combustion ring 113a.Lead-In Area is laid with entrance hole 111a.Described entrance hole 111a comprises hole 111b and lower opening 111c; The inwall of described upper hole 111b is cylindrical; Described lower opening 111c and upper hole 111b concentric are arranged, and the inwall of lower opening 111c is in the truncated cone-shaped of standing upside down.New cable imports into from entrance hole 111a, thus enters into manhole inside.The setting of entrance hole 111a, plays the effect of positioning cable, makes the arrangement of cable more orderly on the one hand, and prevent cable from destroying combustion ring 113a, on the other hand, similar cable can import from same entrance hole 111a, facilitates cable to do functional differentiation.The entrance hole 111a temporarily do not used can plug blocked shot 111d.The setting of lower opening 111c, in order to locate blocked shot 111d, prevents blocked shot 111d from sinking.The setting of blocked shot 111d, enters this manhole in order to prevent rainwater or other foreign material.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
