Description

It is a kind of from drainage machinery arm

Technical field

It the utility model is related to a kind of from drainage machinery arm, and in particular to a kind of arranging certainly for condenser cleaning robots Water mechanical arm.

Background technology

Condenser cleaning robots are the special equipments for thermoelectricity Cooling Tubes of Condenser on-line cleaning, and mechanical arm is cleaning Robot is used for high-pressure water pipe positioning and clamping device.Because mechanical arm is placed in water for a long time, micro-leakage can be occurred unavoidably, one Denier occurs leakage and penetrates into mechanical arm inner chamber body, and mechanical arm will be stopped, so as to cause condenser cleaning robots can not Run well, lose the effect of on-line cleaning.In order to ensure equipment reliably works, both need to be effectively sealed, again Need would leak into the water inside mechanical arm to dispose, currently used technology is periodically to take out mechanical arm from hydroecium to tear open Cleaning and maintenance is opened, is wasted time and energy, cost is high.Therefore, it is necessary to mechanical arm is improved.

Utility model content

In order to solve above-mentioned prior art defect and weak point, the utility model provides for condenser cleaning robots One kind can the infiltration of Hand scarf mechanical arm, and be easy to use and safeguard from drainage machinery arm.

The purpose of this utility model can be achieved through the following technical solutions：

It is a kind of from drainage machinery arm, including mechanical arm body, sealing device, drainage arrangement, if the mechanical arm body by Dry mutually mobilizable mechanical arm forms coherent cavity, and is provided with containment structures in mechanical arm rotation junction；It is described close Seal apparatus, which will be rotated outside junction, to be sealed；The drainage arrangement is connected outside the containment structures and mechanical arm body.

The sealing device uses mechanical seal, and mechanical seal has two relatively independent sealing rings, including with different Thing involvement property, the outer seal ring of sealing solid particle, and the inner seal ring of sealing water.

The containment structures are into an annular, and before containment structures store up full water, mechanical arm is in any angle water not Mechanical arm cavity can be leaked into.

The drainage arrangement includes negative pressure flexible pipe and check valve；The water sucking mouth of described negative pressure flexible pipe one end is placed in containment structures In, other end of discharge outlet is arranged on outside mechanical arm cavity, and the water in mechanical arm is discharged into outside；The pipeline of negative pressure flexible pipe is close Seal through joint cavity wall.

Connected between the containment structures and mechanical arm inner chamber body using a check valve, when the pressure of mechanical arm inner chamber body is big When the pressure of containment structures, check valve is opened, and is otherwise closed.

The beneficial effects of the utility model：

1st, the utility model for condenser cleaning robots provide a kind of simple to operate, dependable performance and good seal from Drainage machinery arm, is not only simple in structure, and cost is cheap and is easily installed and safeguards；

2nd, mechanical arm rotation junction be provided with containment structures, certain infiltration can be pre-stored, containment structures store up full water it Before, mechanical arm is in any angle water all without leaking into mechanical arm inner chamber body；

3rd, absorbed water, can be seeped water with Hand scarf mechanical arm using negative pressure flexible pipe, avoided tradition and tear machine cleaning infiltration open not Necessity trouble, greatly improve the operating efficiency of unit；

4th, using relatively independent sealing device, sealing property of the mechanical arm rotation junction to water is not only increased, Effectively prevent infringement of the foreign matter to seal in cooling water.

Brief description of the drawings

For the ease of it will be appreciated by those skilled in the art that being further described below in conjunction with the accompanying drawings to the utility model.

Fig. 1 is the utility model one kind from drainage machinery arm configuration schematic diagram；

Fig. 2 is the utility model one kind from drainage machinery arm sectional view；

In figure：1st, mechanical arm body, 2, sealing device, 3, drainage arrangement, 4, containment structures, 1-1, mechanical arm are 2-1, outer Sealing ring, 2-2, inner seal ring, 3-1, negative pressure flexible pipe, 3-2, check valve, 3-3, water sucking mouth, 3-4 discharge outlet.

Embodiment

One kind is from drainage machinery arm, referring to figs. 1 to Fig. 2, including mechanical arm body 1, sealing device 2 and drainage arrangement 3； Wherein, mechanical arm body 1 is made up of several mutually mobilizable mechanical arm 1-1, passes through RV reductors between adjacent machine arm Connection, can mutually rotate, its internal coherent cavity of formation between each other；

The containment structures 4 of annular are provided with inside mechanical arm 1-1 rotations junction, the containment structures 4 can prestore certain Infiltration, before containment structures 4 store up full water, mechanical arm 1-1 is in any angle water all without leaking into mechanical arm 1-1 inner chambers Body；Annular in the mechanical structure of containment structures 4, so annular cavity can be formed, axisymmetricly shape, during rotation water all understand from So sink, will not reveal；

The outside of above-mentioned mechanical arm 1-1 rotations junction is provided with sealing device 2；Sealing device 2 uses mechanical seal, machine Tool sealing has two relatively independent outer seal ring 2-1, inner seal ring 2-2；Outer seal ring 2- 1 has foreign matter involvement property, close Sealing body particle, inner seal ring 2-2 sealing water, outer seal ring 2-1 can effectively prevent the impurity in cooling water to inner seal ring 2-2 infringement, ensure sealing properties of the inner seal ring 2-2 to water；

Drainage arrangement 3 includes negative pressure flexible pipe 3-1 and check valve 3-2, and the water sucking mouth 3-3 of negative pressure flexible pipe 3-1 one end is placed in storage In water-bound 4, other end discharge outlet 3-4 passes through mechanical arm 1-1 body walls and mechanical arm 1-1 cavitys, is finally placed in mechanical arm 1- Outside 1 cavity, and negative pressure flexible pipe 3-1 can rotate with mechanical arm 1-1 rotation, and negative pressure flexible pipe passes through mechanical arm 1-1 body walls It should be fixed at via and carry out encapsulation process, check valve 3-2 is fixed between containment structures 4 and mechanical arm 1-1 inner chamber bodies, Present position should (flexible pipe water sucking mouth should point to water storage knot with forming certain space angle at negative pressure flexible pipe 3-1 water sucking mouth 3-3 The radial direction of structure 4 and towards outside), and should ensure that when the pressure of mechanical arm 1-1 inner chamber bodies is more than the pressure of containment structures 4, Check valve 3-2 is opened, and is otherwise closed.

After the infiltration in containment structures 4 reaches to a certain degree, rotating mechanical arm 1-1, adjustment negative pressure flexible pipe 3-1 suction Mouth of a river 3-3 is in locus least significant end, and now the water in containment structures will also be in the structure bottom, at this moment pass through negative pressure Flexible pipe 3-1 discharge outlet 3-4 forms negative pressure, check valve to extracardiac pumping, now containment structures 4 relative to mechanical arm 1-1 inner chamber bodies 3-2 is opened, and is ensured that negative pressure flexible pipe 3-1 smoothly extracts the infiltration in containment structures 4 out, is completed drainage works.

Above content is only to the utility model structure example and explanation, the technology people of affiliated the art Member is made various modifications or supplement to described specific embodiment or substituted using similar mode, without departing from reality With new structure or surmount scope defined in the claims, the scope of protection of the utility model all should be belonged to.
