Detailed description of the invention
Embodiment 1:
As shown in Figure 1, this self-adapted high-efficient pipeline paraffin scraper of this utility model, including straight-bar 1, offer the leather cup 6 of through hole, described straight-bar 1 one end is fixedly connected with helical spring 3, described straight-bar 1 other end runs through the through hole of described leather cup 6 and fixing with this leather cup 6 is connected, and the rim of a bowl of described leather cup 6 is towards described helical spring 3. As it is shown in figure 1, this leather cup 6 is a bowl-shape hollow shell structure, its leading section increases to afterbody successively along the overall diameter of the axial direction of straight-bar 1, and thickness is sequentially reduced.
Work process of the present utility model is as follows:
This utility model is in putting into gathering line, promoted under the pressure effect of leather cup 6 meeting liquid in the wings, to closely be attached on inner-walls of duct at leather cup 6 along the process of pipe motion, the motive force making liquid concentrates on leather cup 6, thus promoting leather cup 6 to travel forward efficiently, thus driving straight-bar 1 to travel forward together with helical spring 3. Due to helical spring 3 spot size and internal diameter of the pipeline (or slightly larger than) about the same, this helical spring 3 can closely be adjacent to inner-walls of duct, in motor process, it can will be attached to the cements such as the waxiness on inner-walls of duct, asphalitine and scratch and take pipeline out of with subsequent fluid.
Itself there is extremely strong elasticity and toughness due to helical spring 3, when running into the hard cement or pipe deforming that cannot strike off, this helical spring 3 can be elongated under leather cup 6 and the combined effect hampering force, helical spring 3 is when being elongated, its length become big while external diameter can diminish so that it is obtained and extremely strong is unlikely to blocking pipeline by property.After by jam point position, helical spring 3 can recover again to be close to the state of tube wall, continues paraffin cutting, until it is reached home.
When pipeline thermal washing, putting into self adaptation paraffin scraper of the present utility model, when waxiness is heated thermal softening, its paraffin cutting efficiency can significantly improve.
Meanwhile, the situation of this utility model pipeline for different-diameter and different wax deposition thickness and intensity, it is possible to design corresponding size carrys out coordinating operation, in order to reach the paraffin cutting effect of the best.
This utility model is compared employing tradition wax ball clearing and is carried out wax removal, it is possible to is prevented effectively from and blocks in pipe deforming section, and then affect the problem that pipeline is properly functioning, it is ensured that the reliability of wax removal work, has higher wax removal efficiency simultaneously.
Embodiment 2:
In order to make this leather cup 6 have the better property passed through in the duct, on the basis of embodiment 1, as shown in Figure 1, leather cup 6 profile described in the utility model is bullet shape, the profile feature of application sub warhead can effectively reduce the fluid resistance that leather cup 6 is subject in the duct, ensure that this utility model moves ahead more glibly in the duct, it is ensured that efficient, the stability of work.
Embodiment 3:
On the basis of above example, as it is shown in figure 1, this utility model is provided with stop convex 2 at the straight-bar 1 of described elastomeric element at the through hole back-end of described leather cup 6. The external diameter of this stop convex 2, more than the internal diameter of the through hole of leather cup 6, thus preventing through hole this stop convex 2 of traverse of leather cup 6, and then separates with straight-bar 1.
This utility model can be prevented effectively from leather cup 6 by the effect of stop convex 2 and come off from straight-bar 1, it is ensured that functional reliability of the present utility model.
Embodiment 4:
For ease of installing/dismounting, on the basis of above example, as it is shown in figure 1, this utility model adopts the straight-bar 1 at described elastomeric element to offer screw thread in the through hole front end of described leather cup 6, and the nut with this threaded engagement is installed.
This utility model, by offering screw thread on its straight-bar 1 and installing nut, greatly facilitates the affected of its installing/dismounting, and the maintenance also allowing for parts is changed, and interchangeability is good.
Embodiment 5:
In order to optimize scheme of the present utility model further, on the basis of above example, as it is shown in figure 1, the nut that this utility model adopts is a pair first locking nut the 4, second locking nuts 5.
This utility model effect by these a pair first locking nut the 4, second locking nuts 5, the fixation to leather cup 6 can be promoted further, also it is prevented effectively from leather cup 6 to come off from the front of straight-bar 1 simultaneously, greatly improves reliable, the stability of utility model works.
Embodiment 6:
In order to optimize scheme of the present utility model further, on the basis of above example, the number of the described leather cup 6 that straight-bar 1 described in the utility model connects can be 1 to 4. Owing to leather cup 6 is usually plastic material, can deform after stress, the contact area of rear liquid and leather cup 6 can reduce, the thrust produced naturally also can reduce, so it is more many to connect the leather cup 6 installed, the thrust that this utility model this self-adapted high-efficient pipeline paraffin scraper is subject in the duct will be more big, thus ensureing that it moves ahead smoothly in the duct to carry out wax removal work, thus ensure that stable, the reliability of work.
Embodiment 7:
In order to promote performance of the present utility model further, on the basis of above example, leather cup 6 described in the utility model adopts polyurethane to make.
Polyurethane material has the anti-wear performance of excellence, anti-flex performance, such that it is able to greatly improve service life of the present utility model, and the non-deformability of work, it is ensured that stable, the reliability of work.
Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, every belongs within protection domain of the present utility model with the same or analogous design of this utility model.
Parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
