Connection radiator drain 7 and blow-down pipe 19 in water tank 25, the roof drain 3 connect top drainpipe 5, the top draining
Pipe 5 is separately connected tank inlet pipe 6 and emergency drainage pipe 8, and the emergency drainage pipe 8 is separately connected radiator drain 7 under
Portion's drainpipe 9, the outer rainwater inspection well 14 of the 9 bottom end junction chamber of lower part drainpipe, the emergency drainage pipe 8 are equipped with and answer
Anxious energy dissipator 2, the emergency energy dissipator 2 includes the S bend pipe 27 of connection emergency drainage pipe 8 and lower part drainpipe 9, described
27 bottom of S bend pipe connect bottom inspection socket 28, exhaust valve 29 and vacuum brake 30 are connected at the top of the S bend pipe 27.
The tank inlet pipe 6 is equipped with water inlet pipe control gate valve 10 and water inlet pipe electric gate valve 11, the water inlet
11 lower end of pipe electric gate valve is connected with the water level controller 15 for being used to monitor four water levels in energy dissipating water tank 1.
The lower part drainpipe 9 is equipped with access hole 4.
The radiator drain 7 is equipped with outlet pipe control gate valve 12, and the emergency drainage pipe 8 is equipped with emergency row
Water pipe control gate valve 13.
It is equipped with and is overhauled into hole 16 at the top of the drain-side water tank 25, it is inside and outside respectively to set frame maintenance ladder 17.
The blow-down pipe 19 is equipped with blow-down pipe control gate valve 18.
In the specific implementation, each spot size of energy dissipating water tank 1 and dischargeable capacity design requirement are as follows: water tank for the utility model
Length A and water tank width B determines that tank height C is determined by designing according to equipment room height, water tank baffle according to equipment room space
23 are arranged in 1 middle position of energy dissipating water tank；Water tank dischargeable capacity [calculation formula are as follows: A*B* (F-E)] is not less than system design row
30 seconds displacement of water flow；The difference of alarm water level G and peak level F are not less than 200mm, generate wrong report to prevent water flow fluctuation
It is alert；The difference of surcharge water level H and alarm water level G be not less than 100mm, away from the top of water tank box 22 be not less than 200mm, in caisson
Rainwater is overflowed from inspection manhole 16.
Each segment pipe size is selected as shown in the table:
Line size selects table
Note: 1, when rain-water drainage amount calculates, storm-water system displacement is subject to the water discharged amounts of top drainpipe (5)；
2, drainage system against rain vent flow is referring to the 4.9.22 articles table choosing of " Code for design of building water supply and sewerage " GB50015
With.
Energy dissipating principle and control mode: normal condition: emergency drainage pipe control gate valve 13 is normally closed, water inlet pipe control gate valve 10
Normally opened, water inlet pipe electric gate valve 11 is normally opened, and outlet pipe control gate valve 12 is normally opened.
Rainwater is controlled by entering tank inlet pipe 6 through top drainpipe 5 after the collection of rain water on roof bucket 3 through water inlet pipe
Gate valve 10 and water inlet pipe electric gate valve 11 enter in the influent side water tank 24 of energy dissipating water tank 1, and rainwater pressure is released, at this time water
Stream is in turbulent condition, and influent side water tank 24 goes out after filling through entering drain-side water tank 25 at the top of water tank baffle 23, then through water tank
Water pipe 7 is discharged into lower part drainpipe 9, eventually enters into outdoor rain inspection shaft 14.
Rainwater is communicated with the atmosphere in energy dissipating water tank 1, and energy and pressure are released, to achieve the purpose that decompression.By
In the caliber of lower part drainpipe 9 and radiator drain 7 level-one bigger than the caliber of top drainpipe 5 and tank inlet pipe 6, so
The displacement of lower part drainpipe 9 is more much larger than the displacement of top drainpipe 5, it is ensured that in energy dissipating water tank 1 will not water storage it is too many,
It can discharge at any time clean.
Since emergency drainage pipe control gate valve 13 is in close state, emergency energy dissipator 2 does not work.
Water level controller 15 monitors the water level of energy dissipating water tank 1 and communicates with monitoring center and alarm protection.When monitoring
When the water level of energy dissipating water tank 1 reaches alarm water level G, start alarm equipment alarm；When the water level for monitoring energy dissipating water tank 1 reaches superelevation
When water level H, water inlet pipe electric gate valve 11 is closed in linkage, and system stops draining, and rain water on roof sluices via discharge opening；When supervising again
When measuring the water level of energy dissipating water tank 1 and reaching lowest water level E, water inlet pipe electric gate valve 11 is opened in linkage, and system restores draining.
After receive the alarm signal, administrative staff can arrive the working condition of site inspection energy dissipator, if water tank overflow, let out
Situations such as leakage, blocking, water inlet pipe control gate valve 10 can be closed, suspend the working condition of energy dissipating water tank 1, system can also be transferred to
Emergency rating.
Emergency rating: when water tank maintenance or circuit failure, system can be transferred to emergency rating, emergency drainage pipe control gate valve
13 open, and water inlet pipe control gate valve 10 is closed, and water inlet pipe electric gate valve 11 is normally opened, and outlet pipe control gate valve 12 is closed.
Rainwater enters through top drainpipe 5 through emergency drainage pipe control gate valve 13 after being collected by rain water on roof bucket 3 meets an urgent need
Drainpipe 8, then energy dissipator 2 of being met an urgent need are discharged into lower part drainpipe 9, eventually enter into outdoor rain inspection shaft 14.
Due to being equipped with S bend pipe 27, water flow flowing full formed here, furthermore the pipe of emergency drainage pipe 8 in emergency energy dissipator 2
Diameter level-one smaller than the caliber of top drainpipe 5, rainwater forms water plug herein, so that hydraulic pressure is reduced, energy is consumed.Together
When lower part drainpipe 9 caliber two-stage bigger than the caliber of emergency drainage pipe 8, water note obtains dissipating herein and spill, and energy is sufficiently released
It puts, to achieve the purpose that decompression.
To prevent 27 top pneumatosis of S bend pipe from leading to impeded drainage, setting exhaust valve 29 excludes excessive gas, to guarantee rainwater
Abundant pressure release and suction effect is not formed, sets vacuum brake 30 again at 27 top of S bend pipe, generate 27 top of S bend pipe neither
Positive pressure does not also generate negative pressure.Since the caliber of emergency drainage pipe 8 is smaller, the requirement of design discharge, institute is not achieved in System drainage amount
It can not be used for a long time with emergency drainage state.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
