13 and be arranged 13 upper end of airtight and watertight padding sealing clamp 14 composition.
Further, the lower space of heavy silt room 5b is designed to be more than upper space, it can be to avoid top silt mistake
Unity is formed indoors again, and sand discharge is unsmooth when silt being caused to remove.Meanwhile going out to further avoid the heavy indoor silt of silt
The overweight problem in existing top is equipped with several partition board 5e along its length in heavy silt room 5b, and partition board 5e is by heavy silt room 5b points
It is divided into several independent chambers so that each indoor total volume of silt of chamber further decreases, and correspondingly, silt gross weight is also dropped
Low, the silt pressure for being located at bottom reduces, and unity situation is resolved, it is ensured that smooth when spoil disposal sand.Preferably, each
Cavity bottom is formed with funnel shaped training for sediment portion 5f, and training for sediment portion can make silt exclude more clean thorough.Each chamber is equal
It is corresponding with independent silt entrance 5g and spoil disposal sand hole 5d.
In order to realize being automatically drained out for silt, it is located at the bottoms supporting rack 6a in the middle part of heavy silt room 5b and is equipped with compression power transmission bullet
Spring 8 is equipped with mounting groove compressing the 8 corresponding spoil disposal sand road bottom surfaces 5c of power transmission spring, is sequentially equipped with from the bottom to top in mounting groove
Pressure sensor 9, seal gasket 10 and sealing force transmitting board 11 compress power transmission spring 8 and are clamped in supporting rack 6a and sealing force transmitting board
Between 11；The pressure sensor 9 is connect with external control unit outside circuit.Power transmission spring is compressed, can not only transmit pressure, together
When can also play the role of compressing sealing power transmission, avoiding water and silt from entering in pressure sensor influences its normal work.
It is that relevant parameter is arranged in pressure sensor by external control unit outside in use, first according to calculating.When work,
When pressure sensor reaches preset value, illustrate the heavy indoor silting of silt to predetermined altitude.At this point, being controlled by outside
Unit, control hydraulic station work, hydraulic station driving lifting cylinder move down, and so that seal rubber plug is taken off out of spoil disposal sand hole, heavy silt
Indoor silt enters spoil disposal sand road under the action of dead weight and top hydraulic pressure, is drained into external silt stockyard from spoil disposal sand road.
After opening the predetermined time, lifting cylinder uplink makes seal rubber plug get back into again in spoil disposal sand hole, completes a spoil disposal Sha work
Sequence.
Embodiment provided above is the better embodiment of the utility model, only is used for facilitating illustrating the utility model, and
It is non-to impose any limitation on the present invention, any those of ordinary skill in the art, if not departing from
In the range of the carried technical characteristic of the utility model, locally changes or repair using made by the utility model disclosed technology content
The equivalent embodiment of decorations, and without departing from the technical characteristics of the utility model content, still fall within the utility model technical characteristic
In the range of.
