Even in severe blocking condition, the sewer can be effectively dredged, and the dredging effect is excellent.

Description

Half water odd test vacuum dredging machine

Technical field

The utility model relates to a kind of dredging machine, specifically, relates to a kind of half water odd test vacuum dredging machine.

Background technology

Sewer blockage is one of problem common in the daily life, usually be because some nonstandard daily habitses are assembled foreign matter and caused that the sewer impeded drainage results in blockage in sewer, if untimely cleaning dredging, not only because stopping up the contaminated wastewater environment of assembling, cause various stenches, and the waste water that stops up is of value to growing of harmful germ, have a strong impact on indoor environment and people's health, and long-term obstruction of sewer can cause corrosion to sewer itself, the application life of infringement drain pipe.

Sewer dredger commonly used is generally simple dredging device now, is made of an elastic cup and one handle, utilizes the effect of drain pipe internal gas pressure to dredge, though use simple, but its manipulation strength is excessive, in the situation that some blockage are serious, treatment effect is just very undesirable.Be that 01274034.9 drain dirt cleaner also is to adopt identical action principle just like application number also, utilize handle and piston to reduce to a certain extent user's operation easier, but because the interface channel place of cylinder and leather cup is comparatively narrow, the pull of vacuum that the pulling piston is formed can not fully act on sewer, cause its result of use good not, the simultaneously use of handle is still comparatively required great effort to a certain extent.

Therefore, a kind of user's easy manipulation and uses that to dredge the good sewer dredger of effect required as people of can allowing of design.

The utility model content

In order to address the above problem, the utility model provides a kind of user's of allowing easy manipulation and half good water odd test vacuum dredging machine of result of use.

To achieve these goals, the technical solution adopted in the utility model is as follows:

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.

Embodiment

Extremely shown in Figure 6 such as Fig. 1, this half water odd test vacuum dredging machine, comprise be the cylinder tubular take out the cylinder 1, be installed on and take out in the cylinder and the piston 2 that matches, be connected on the piston and with take out a sealing ring 10 of inwall coupling, the piston rod 3 that is connected with piston, be positioned at and take out the press rods 5 that an outside and end are connected with piston rod by bearing pin, the bracing frame 6 that top is connected with the press rods middle part by bearing pin, the connecting rod 7 that the middle part is fixedly connected with the bracing frame lower end, be fixed in the connecting rod two ends and be connected in take out a upper portion side wall and by bearing pin with take out the U-shaped girth member 8 that is connected and fixed of cylinder, top is by screw thread and the spacing ring 9 of taking out a lower end and being connected, and annular snap is connected to the seal gasket 4 of spacing ring lower end.

Wherein, sealing ring arranges around piston one circle, and piston is fully contacted with taking out an inwall, has guaranteed the sealing of piston movement, takes out a bottom when making piston movement and can form negative pressure of vacuum, produces pull of vacuum.The press rods front end is U-shaped, and piston rod top is connected in this U-shaped groove by bearing pin; It is U-shaped that bracing frame top also is, and the press rods middle part also is connected in this U-shaped groove by bearing pin, guaranteed on the one hand the stability that connects, these two bearing pins are all detachable on the other hand, the utility model not the time spent bearing pin can be taken out, press rods is taken off placement, saves the space.Press rods has adopted lever principle, take bracing frame as fulcrum, for reaching the labour-saving purpose, press rods arranges longer usually, even if the weak user of strength also can normal operating, the lower end of bracing frame then is fixed taking out cylinder, dual mode is arranged, a kind of is to be directly installed on the top edge of taking out cylinder, another kind then is horizontally set one connecting rod in taking out cylinder, and the bottom of bracing frame is connected in the connecting rod middle part, and the two ends of connecting rod are then by U-shaped girth member and the top edge clamping of taking out cylinder, reduce thus the length of resistance arm, make the pressing operation of press rods more laborsaving.

Taking out a bottom is connected with spacing ring by screw thread, the internal diameter of spacing ring is slightly less than the internal diameter of taking out cylinder, prevent that piston from dropping out from taking out a lower end, and the lower end of spacing ring is provided with the shackle member that a circle is used for installing seal gasket, the cross section of this shackle member is down T-shape, correspondingly, has the buckling groove that is complementary with this shackle member shape on the seal gasket, so snap fit also extremely is convenient to change, if rubber cushion is aging, device body only need be changed parts and can recover normal operating condition without integral replacing.Seal gasket adopt Waterproofing/oilproofing and absorption affinity preferably elastic caoutchouc make, seal with the sewer mouth place when being mainly used in dredging and be connected, prevent gas leakage, guarantee the stability of formation pull of vacuum; And the bottom of sealing rubber cushion can design sizes and shape, adapting to the sewer mouths of different sizes, provides the seal gasket of two kinds of forms such as Fig. 5 and Fig. 6.Need to prove, which kind of shape no matter seal gasket adopt, and the size of choosing is all as much as possible little, prevents that vacuum pressure is large, and the seal gasket upset affects result of use.

In order to realize better dredging, increase the operational readiness of dredging, the piston lower end also is provided with the spinning disturbing flow device.Specifically, this spinning disturbing flow device comprises the steel cable 11 that an end is connected with the piston lower end by clamp nut, the axis of rotation 12 that is flexibly connected with the steel cable other end, and 2～5 at the uniform blade 13 of axis of rotation outer circumference.Wherein, described blade is obliquely installed with respect to axis of rotation.In order to guarantee the normal use of axis of rotation, have a through hole on the axis of rotation, steel cable then passes this through hole and is flexibly connected, and comes off in order to prevent axis of rotation, steel cable is provided with the positioning limiting fixator that is fixedly connected with steel cable at the two ends of this through hole, guarantee that axis of rotation can only move in the steel cable end.And common employing of axis of rotation and blade has the material making that certain degree of hardness has certain toughness, neither can damage drain pipe, can play the flow-disturbing effect again.

According to above-described embodiment, just can realize well the utility model.What deserves to be explained is; under the prerequisite based on the said structure design; for solving same technical problem; even some that make at the utility model are without substantial change or polishing; the essence of the technical scheme that adopts is still consistent with the utility model, also should be in protection domain of the present utility model.
