Abstract

The utility model discloses a device for intercepting a float bowl of an intercepting well. The device comprises a rotating plate arranged on the side wall of the intercepting wheel, wherein the middle part of the rotating plate is hinged to the side of a drainage outlet of the intercepting well; a float bowl is arranged at one end of the rotating plate, and a drainage outlet opening and closing plate matched with the drainage outlet of the intercepting well is arranged at the other end of the rotating plate. When the drainage outlet opening and closing plate of the device is closed, the closing force is realized by water power, the buoyancy force only needs to realize the opening adjustment of the drainage outlet opening and closing plate, and thus the device is low in requirement for the buoyancy force and low in restriction by the buoyancy force; the rotating plate in the device is hinged to the side wall of the intercepting well, the opening control actions of the drainage outlet opening and closing plate are performed for rotating the rotating plate, small moving force needs, the weight of the float bowl is indirectly reduced, automatic interception of buoyancy force under different working conditions is realized, and the interception is more flexible and reliable; the device is few in components and parts, simple in structure and good in manufacturability.

Description

Catchpit floating drum cut-off equipment

Technical field

The utility model relates to drainage pipeline networks equipment, refers to particularly a kind of catchpit floating drum cut-off equipment.

Background technology

In drainage system facility, conventionally need to dam according to pool inner water position situation, with adjusting water outlet uninterrupted, wherein, drive and realize the cut-off equipment that water flow regulates by buoyancy, do not need the advantage of extra power equipment to there is wide application prospect because it has, but, the cut-off equipment that relies on buoyancy to dam at present, because mobile conditioning equipment is heavier, need larger buoyancy, exists buoyancy is required to high shortcoming; And mobile conditioning equipment complex structure.

Summary of the invention

The purpose of this utility model will provide a kind of catchpit floating drum cut-off equipment exactly, and this cut-off equipment is simple in structure, has realized pure water power and has opened and closed, and be subject to buoyancy restriction little.

For achieving the above object, the technical solution adopted in the utility model is: a kind of catchpit floating drum cut-off equipment, comprise the swivel plate being arranged on catchpit sidewall, described swivel plate middle part is hinged on by catchpit outfall side, one end of described swivel plate is provided with floating drum, and the other end is that the outfall coordinating with catchpit outfall opens and closes plate.

The utility model, by the two ends at swivel plate center of rotation, floating drum is set respectively and outfall opens and closes plate, and swivel plate is arranged near outfall, floating drum rotates under water buoyancy, thereby the outfall that drives its other end opens and closes plate rotation, realize the keying of outfall, wherein, when liquid level is lower than setting when liquid level, outfall opens and closes plate in full-gear, now draining downstream, when liquid level is higher than setting when liquid level, floating drum is because of the rotation of buoyancy driven rotary plate, and then drive outfall keying plate slowly to close, and in the time that liquid level drops to setting liquid level, the gravity of floating drum and swivel plate makes equipment reverse rotation, thereby valve is opened completely, when the outfall keying plate of this device is closed, it is closed power and realizes by waterpower self, and buoyancy only need be realized the adjusting of outfall keying plate aperture, and therefore this device is not high to the size requirements of buoyancy, is subject to the restriction of buoyancy little, swivel plate in this device is hinged on catchpit sidewall, outfall opens and closes performing an action as swivel plate rotates of plate aperture control, and the locomotivity needing is less, has indirectly reduced the weight of floating drum, be conducive to realize the buoyancy automatic-diversion closure under different operating modes, hold back more flexibility and reliability, this device component are few, simple in structure, good manufacturability.

Further, it is hollow airtight cylindric that described floating drum is, and an end face of described floating drum is fixedly connected with described swivel plate, and the cylinder face of described floating drum is perpendicular to described swivel plate.

Further, described outfall opens and closes plate to be pressed close on the face of catchpit sidewall to have annular holddown groove, in described holddown groove, is provided with sealing ring.

Further, the pin joint between described swivel plate and catchpit sidewall is in the other top of catchpit outfall side.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, is convenient to more clearly understand the utility model, but they do not form and limit the utility model.

As shown in Figure 1, a kind of catchpit floating drum cut-off equipment, comprise the swivel plate 302 being arranged on catchpit 301 sidewalls, described swivel plate 302 middle parts are hinged on the catchpit 301 other tops of outfall 310 sides, one end of described swivel plate 302 is provided with floating drum 303, the other end is that the outfall coordinating with catchpit 301 outfall 310 opens and closes plate 304, it is hollow airtight cylindric that described floating drum 303 is, one end face of described floating drum 303 is fixedly connected with described swivel plate 302, the cylinder face of described floating drum 303 perpendicular to described swivel plate 302(as shown in Figure 2), described outfall opens and closes plate 304 and presses close on the face of catchpit 301 sidewalls to have annular holddown groove 305, in described holddown groove 305, be adhesive with sealing ring 306(as shown in Figure 4).

As shown in Figure 3, hinged between swivel plate 302 and catchpit 301 sidewalls is that swivel plate 302 is positioned on sidewall metope by embedded steel tube 307, location-plate 308 makes swivel plate 302 axial location by pre-embedded bolt 309, and swivel plate 302 can be rotated freely around embedded steel tube 307 center.

The course of work of the present utility model is as follows: when liquid level is lower than setting when liquid level, as shown in Figure 5, floating drum 303 falls, and outfall opens and closes plate 304 and staggers with outfall 310, and the device with float that originally dams is in full-gear, now from delivery port 310 draining downstream; When liquid level is higher than setting when liquid level, as shown in Figure 1, floating drum 303 is because of buoyancy rising, driven rotary plate 302 rotates, and then drive outfall keying plate 304 down to rotate, outfall open and close plate 304 along with the rising of liquid level slowly with outfall 310 closures, the device with float that finally originally dams is in closed condition; And in the time that liquid level drops to setting liquid level, the gravity of floating drum 303 and swivel plate 302 makes equipment reverse rotation, thereby this device is opened completely.

This apparatus structure is simple, has realized pure water power and has opened and closed, and be subject to buoyancy restriction little, can be used for sewage in drainage system catchpit dam equipment or the dirty rainwater equipment that dams that separates in well of rain, also can be used in the various ponds body of plumbing facility.
