It opens drainage hole 221 when larger quickly to be drained, water can be resetted and be supported under the action of compressed spring 225 again after reducing
It is connected to 22 lower surface of drainage protective plate.
It is equipped with what control draining pump 31 opened and closed in sump 3 due to being difficult to observe the situation inside sump 3 referring to Fig. 4
Liquid level sensor 32 avoids the draining idle running with draining pump 31 not in time to open and close draining pump 31 in time.
Referring to Fig.1, foundation pit 1 is externally provided with the drain 4 of the water for accommodating the discharge of draining pump 31, by what is be discharged in foundation pit 1
Water is drained into drain 4, and observes the variation containing object in attention discharge water for the convenience of the users, close in drain 4
31 side of draining pump is communicated with observation slot 41, and the discharge ends of draining pump 31 are located in observation slot 41.
Referring to Fig.1 and Fig. 5, in order to further facilitate observation of the user to pump drainage water in observation slot 41, draining pump 31
Discharge ends include the hose 311 that one end is protruded into observation slot 41, are fixed in observation slot 41 along the fitting of its own width direction
Fixed board 411, fixed plate 411 is located at hose 311 close to 4 side of drain and its top is located at 41 top lower section of observation slot, fixed
The through-hole 4111 that water supply stream passes through is provided on plate 411,311 end of hose, which is connected with, can keep off the closure plate 44 being set to outside through-hole 4111,
Closure plate 44 is located at fixed plate 411 close to 4 side of drain.Under peacetime state under the impact of discharge water, closure plate 44 and fixed plate
411 do not abut mutually, and water passes through from through-hole 4111；Hose 311 is pulled, by the gear of closure plate 44 outside through-hole 4111, water is from fixation
Pass through above plate 411, convenient for users to observing the water of discharge.
Referring to Fig. 5, closure plate 44 occurs deviating or angled without being bonded to each other with fixed plate 411 in order to prevent,
Several horizontally-guided bars 42 uniformly distributed around its center are connected on closure plate 44,42 outer peripheral surface of horizontally-guided bar is connected to through-hole 4111
Inner peripheral surface is fixed far from 411 one end of fixed plate and 311 phase of hose.
Referring to Fig. 5, when due to proper drainage, closure plate 44 may be kept off on the flow path of water, so that water flow is disorderly splashed, be made
At the observation attached subaerial miriness of slot 41, the surface of 44 sliding path of closure plate is equipped with water fender 43, water fender 43 and fixed plate
411 phases are fixed and with observation slot 41 with wide.
The course of work is summarized:
After precipitation, filter plate 21 is filtered the water at 1 bottom of foundation pit when water is smaller；Water is more than the height of filter plate 21
When, it is filtered together by filter plate 21 and drainage protective plate 22；When water is very big, drainage hole 221 is opened tight to help
Anxious draining, draining is more smooth while reducing sand running-down.
When pump drainage, filtered rainwater in foundation pit 1 etc. is conveyed by gutter 2, and is flowed into sump 3,
Pump drainage is carried out to the water in sump 3 by draining pump 31 again, is ultimately discharged into drain 4.
When needing to observe the variation in discharge water containing object, hose 311 is pulled, by the gear of closure plate 44 outside through-hole 4111, water
It can only pass through above fixed plate 411 and water fender 43, convenient for observing the situation for flowing through pump drainage water at observation slot 41.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
