Abstract

The utility model discloses an automatic sewage stop and flood drainage floating gate which is composed of a gate body, a base, a guide pulley groove, and a guide pulley, wherein, the gate body is a reverse hollow rectangular trapezoid body, the gate body is an isosceles trapezoid in the direction of front view, and is a rectangular trapezoid in the direction of side view; the periphery of the gate body is provided with sealing rubber. The plane which is formed by rectangular sides is at the sea water side, and the plane which is formed by trapezoid sides is at the sewage side. The sea water can not generate buoyancy to the gate body, and back flow of the sea water can not occur. When flood drainage after rainfall is carried out, flood generates buoyancy to the gate body, and the gate body is opened. The gate has a hollow structure, and effective regulation can be carried out according to the opening requirement of the gate.

Description

Automatically cut dirty, floating dam drains off floodwaters

The gate that the utility model relates to and a kind ofly is used for that sewage dams, sewage and rainwater do not have the tidal channel of shunting.

The conventional method that sewage dams is at the exit or entrance of a clitch of drainning off floodwaters overflow weir or gate to be set.During no rainfall, wastewater level is lower, need not to open a sluice gate to drain off floodwaters; Otherwise, need open a sluice gate flood discharge.Overflow weir is too high, can influence to drain off floodwaters; Cross lowly, seawater (or river, hereinafter be example with the seawater) can pour in down a chimney and cuts a dirty house steward, increases the operating cost of Sewage Plant.

Common gate, the switch gate needs power, electronic headstock gear often is subjected to outage restriction, operating reliability, antitheft, anti-destructive is relatively poor, invests bigger.

The utility model purpose is to overcome the deficiencies in the prior art, provides a kind of: close under normal conditions, can stop seawater to enter and cut dirty house steward; When having rainfall to drain off floodwaters, in time open the novel gate of flood discharge automatically.

The purpose of this utility model is achieved in that the floating dam of design is made up of lock body, pedestal, guided wheel slot, guide wheel etc.The lock body is the hollow right-angled trapezium body of a handstand, just is being considered as isosceles trapezoid, and side-looking is a right-angled trapezium.The plane that right-angle side forms is in the seawater side, and the plane that trapezoidal side forms is in the sewage side; The periphery of lock body is provided with caulking gum.Pedestal is the protruding seat of rectangle, is fixed on the furrow bank; Be provided with guided wheel slot above pedestal, the below is provided with baffle plate; Upper and lower guide wheel all is fixed on the lock body.

Because the utility model is taked said structure, seawater can not produce buoyancy to the lock body, thereby seawater can not pour in down a chimney; When having rainfall to drain off floodwaters, flood produces buoyancy to the lock body, and when buoyancy equaled the lock body weight, gate moved along with upper and lower guide wheel rises in guided wheel slot and on the baffle plate respectively, realizes gate opening; When flood level was reduced to certain position, the lock body was closed automatically.Be unlikely again because of flood impacts the displacement of lock body takes place.This novel gate is a hollow-core construction, also can be according in the different sewage position, and the needs of gate opening are effectively regulated.

Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:

Accompanying drawing 1, the utility model design principle figure;

Accompanying drawing 2, the utility model example structure schematic diagram;

Accompanying drawing 3, the utility model embodiment A-A sectional drawing;

Accompanying drawing 4, the utility model embodiment partial enlarged drawing;

As shown in Figure 1, lock body (1) is the hollow right-angled trapezium body of a handstand, just is being considered as isosceles trapezoid, and side-looking is a right-angled trapezium.The plane ABCD that right-angle side forms is in the seawater side, be that seawater face ABCD plane is perpendicular to horizontal plane, the plane that trapezoidal side forms is in the sewage side, and caulking gum (6) A ' B ' on the lock body (1), B ' C ', C ' D ' form plane A ' B ' C ' D ' and be parallel to and approach very much the ABCD plane.Like this, it is very little that seawater forms buoyancy to lock body (1), can ignore to the buoyancy of lock body (1) with respect to sewage.When flood rises to certain water level, when the lock body was produced buoyancy and equals lock body (1) weight, gate opening drained off floodwaters.And the water level of seawater height can not influence the on off state of lock body.

Shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, lock body (1) is hollow, can add weight in the body, thereby reaches regulating gate open degree purpose when same sewage position, has promptly changed lock body (1) and has opened constantly at different flood levels.Lock body (1) elevation is an isosceles trapezoid, spongy foaming caulking gum (6) is embedded in the circumferential groove of lock body (1) by glue is perpendicular, make lock body (1) switch freely, sealing is difficult for easily card, be convenient to caulking gum (6) is overhauled, and frictional force is more much smaller than common side seal generation frictional force between lock body (1) and the pedestal (4), easier realization switch, caulking gum (6) life-span is longer.

Gate pedestal (4) is protruding seat, and the cross section is a rectangle, is fixed on the furrow bank concrete cushion (8), overcomes so easily to accumulate foreign material when drainning off floodwaters in the common recessed pedestal, influences the shortcoming of knife switch and sealing, and whole pedestal (4) adopts corrosion resistant plate to make, and maintains easily.

The gate location is by the six pairs of upper blocks (2) on the lock body (1), and one pair of lower tumbler (5), guided wheel slot (3) and baffle plate (7) are realized.On the equal stepping brake body (1) of last lower tumbler (2) (5).Guided wheel slot (3) is arranged on pedestal (4) top, and plate washer (7) is arranged on the below of pedestal (4).

Claims

1, a kind of automatic section dirt, the floating dam that drains off floodwaters are made up of lock body, pedestal, guided wheel slot, guide wheel, it is characterized in that: the lock body is the hollow right-angled trapezium body of a handstand, just is being considered as isosceles trapezoid, and side-looking is a right-angled trapezium; The periphery of lock body is provided with caulking gum, and pedestal is the protruding seat of rectangle, is provided with guided wheel slot above pedestal, and the below is provided with baffle plate; Upper and lower guide wheel all is fixed on the lock body.
