The utility model discloses a set up two elevator pumps and realize the effect that duplex heat was equipped with, one can avoid the unit not enough at the drainage ability under the condition of rainfall surge, two lead to drainage system inefficacy and increase regional drainage burden when can handling the unit trouble.
The utility model discloses in, for the setting of two elevator pumps of reasonable layout, can set up wash port 50 and gate 30 to be located between two elevator pumps.
The utility model discloses a gate structure can adopt to go up and down to open and close or the upset is opened and close:
the gate structure opened and closed by lifting opens the drain hole by lifting the gate or closes the drain hole by descending the gate. Specifically, the gate can be connected with a lifting mechanism, and after the gate is lifted by the lifting mechanism, the gate opens the drain hole, so that the overflow well is communicated with the inspection well. When hoist mechanism sets up, can adopt the worm to connect the gate and make the worm vertically wear to the inspection shaft place area more than the ground basis, set up the support that supplies the worm to hang on the ground basis to be equipped with the handle and set up in the worm tip, can make things convenient for the manual work to promote the gate after making the worm rotate through the twist grip with this, this manual lifting structure belongs to prior art, and this application is no longer further repeated. Or, the lifting mechanism can adopt an electric structure, the two sides of the drain hole are provided with chutes for the insertion of the two side edges of the gate, and the top of the gate is connected with an electric lifting mechanism, such as an electric lifting appliance like a winch, so as to electrically open and close the gate.

In the case of the arrangement of the flap gate structure according to the above-described embodiment, the second stopper 3032 is provided above the gate so as to be fixed to the inner wall of the overflow well 102 and so as to be located above the upper edge of the drain hole, so that the flap 302 is stopped by the second stopper 3032 after being turned up and cannot be turned up.
The utility model discloses a set up the aim at of second dog, when the rainfall increases drastically, the opportunity that the water flows backward probably takes place in an instant, the flashboard can overturn excessively because of the drainage is fiercely this moment, if at this moment after being strikeed the water that flows backward the flashboard can continue to upturn to the overflow well inner wall of laminating above the wash port, lose the effect that the gate was closed, and through the effect that blocks of second dog, can avoid the flashboard to continuously upturn, at this moment under the impact that the water flows backward, the flashboard can be blockked by first dog after being promoted in the reverse direction and close the gate, thereby seal the wash port and avoid flowing backward.
In addition, in order to prevent the gate plate from falling to close the drain hole due to the violent impact of the flowing water, the level of the lowest position of the second stopper 3032 may be set lower than the set height of the rotating shaft.
The utility model discloses in, set up the level of the extreme lower position of second stopper into the level that is less than the pivot, it sets up to aim at, when making the flashboard overturn to overflow well one side, can't overturn to being the level, but be overflow well lopsidedness's structure earlier on, this slope structure can ensure when flowing backward, water impact can make the reverse upset of flashboard smoothly, and if do not have this structure setting, then probably take place under the violent circumstances of water flowing backward, lead to the flashboard to keep the level for a long time to lose the effect of shutting down the floodgate.
The second stop can have a flexible structural arrangement according to the actual building conditions and the size of each structural member. For example, as shown in fig. 6, the second stopper 3032 may be configured as a strip-shaped structure, such that after the second stopper is obliquely disposed, the high-position end is connected to the inner wall of the overflow well, and the low-position end falls obliquely toward the first water outlet pipe, so that the second stopper 3032 of the strip-shaped structure is integrally inclined toward the first water outlet pipe, at this time, the maximum opening degree of the flap may not make the flap horizontal, and when the water body flows backwards, the flap can be smoothly turned over in the reverse direction to close the water discharge hole.
Alternatively, as shown in fig. 5, after the second stopper 3032 is arranged to be horizontal, a sub-stopper 3032-1 is arranged on the lower surface of the second stopper 3032 to be fixedly connected with the second stopper 3032, so that the lower surface of the second stopper 3032 sinks to a certain height and then is lower than the horizontal height of the center of the rotating shaft. In actual installation, particularly, the size of the structural device is large, so that even if the lower surface of the second stop block is level with the center of the rotating shaft, the gate plate can still be inclined towards one side of the first water outlet pipe when being turned up to the maximum opening degree. In addition, in order to keep the second block to have better support when the opening degree of the turning-up of the gate plate is maximum during normal drainage, an angle iron structure 304 can be arranged on the upper surface of the second block as a measure for enhancing the structural strength.
To sum up, the utility model discloses use in the lower area of part relief, set up one kind in the terminal rainwater well in this area and prevent the gate structure that flows backward, this structure is in rainwater pipeline in the course of the work, and the valve is opened when normal drainage and is carried out normal drainage, and is higher than rainwater pipeline through closing the gate when the river course water level to open the elevator pump, with this with the drainage river course behind the rainwater suction overflow well, prevent that the river from flowing backward. During operation, when the river course is rainy, the machine is started, the gate is sunk/overturned to the drain hole, the first/second lifting pump is opened, rainwater in the inspection well is pumped into the overflow well, the elevation of the drain outlet (the second water outlet pipe) of the overflow well is set to be higher, and the rainwater level higher than the river course water level can be drained into the river course through water potential difference flow.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
