Abstract

The utility model discloses an automatic charging apparatus for bubble discharging balls. The automatic charging apparatus comprises a storage mechanism and a dropping mechanism which comprises a main path, a main path transmission mechanism, a bypass communicating with the main path and the storage mechanism and a bypass transmission mechanism. A switching device is arranged on a communication port of the bypass and the main path. When a bubble discharging ball is conveyed on the main path transmission mechanism, the switching device closes the communication port. When automatic charging apparatus works, a bubble discharging ball in the storage mechanism is conveyed to the communication port of the bypass and the main path after passing through the bypass and the bypass transmission mechanism. When the switching device is turned on, the bubble discharging ball enters into the main path, and is thrown to a wellhead via the main path transmission mechanism when the switching device is turned off. When the switching device is turned on again after the bubble discharging balls are thrown out, a follow-up bubble discharging ball enters into the main path from the bypass. The process repeats continuously, which realizes continuous charging of bubble discharging balls, improves charging speed, and further improves natural gas exploitation efficiency and stability of natural gas exploitation work. Waste of natural gas discharged into air can be avoided.

Worm gear 82 and toothed disc 63 can drive by same driving mechanism, also can be driven by different driving mechanisms respectively, and two kinds of drive forms guarantee that all in the process of 81 back and forth movements of sealed end, toothed disc 63 can rotate predetermined angular.
Worm gear 82 and toothed disc 63 can drive by the first driving mechanism, and as shown in Figure 2, the first driving mechanism drives driving gear 64, driving gear 64 and worm gear 82 and toothed disc 63 engagements.Worm gear 82 also can be driven respectively by the second driving mechanism and the 3rd driving mechanism with toothed disc 63, guarantees that worm gear 82 satisfies certain rotation than getting final product with toothed disc 63.
Simultaneously revolving dial 61 also turns over identical predetermined angular, and predetermined angular is 360 when spending, sealed end 81 round trips, and revolving dial 61 rotates weeks, and predetermined angular is 720 when spending, sealed end 81 round trips, revolving dial 61 rotated for two weeks.
The predetermined angular value is not limited only to the described situation of above-described embodiment, and when predetermined angular was spent greater than 360, sealed end 81 each coming and going all had the bubble vollyball to enter main road.Certainly, predetermined angular also can less than 360 the degree, specifically can according to the natural gas well to the bubble vollyball the demand setting.When revolving dial 61 had a plurality of groove 62, the less of predetermined angular setting also can satisfy the demands.
In the another kind of concrete mode, switching device 8 can be telescoping cylinder, and sealed end 81 is arranged at the telescopic end of telescoping cylinder; Revolving dial 61 can be controlled by crank and rocker mechanism.
Similar with upper embodiment, in the process of a back and forth movement of telescopic end, revolving dial 61 rotation predetermined angulars, concrete is also similar to the above embodiments, can according to the natural gas well to the demand of bubble vollyball and the structure of revolving dial 61, predetermined angular be set.
Obviously, the form of structure of switching device 8 not only is confined to the described situation of the various embodiments described above, and other mechanisms that can realize sealed end 81 back and forth movements also can use in the utility model; The driving mechanism of revolving dial 61 also not only is confined to the described situation of the various embodiments described above, and other mechanisms that can realize that revolving dial 61 rotates also can be applied in the utility model.
In another preferred embodiment, spool 41 is installed in by bearing 43 in the valve body 44 with main road 3, spool 41 shutoff main roads 3.
Spool 41 can be done flip-flop movement, also can be to rotate continuously, and in the process of spool 41 upsets or rotation, the sealing that also can keep main road 3.Sealed end 81 is opened connected entrance 7, and the bubble vollyball enters main road 3, during spool 41 upset, throws in the bubble vollyball.
Concrete, the upset of spool 41 or rotation are driven by the 4 wheel driven actuation mechanism, in the process of spool 41 upsets, the sealing that keeps main road 3, so that bubble vollyball automatic filling device is thrown in the process of bubble vollyball, realized the sealing to natural gas well well head, natural gas can not be discharged in the air, can not cause the waste of natural gas.
In the respective embodiments described above, stocking mechanism 1 comprises storage bar 11 and large dial wheel 12, can hold a plurality of bubble vollyballs in each storage bar 11, and large dial wheel 12 can be sent to storage bar 11 port 9 of bypass 5 and stocking mechanism 1 successively.
Through hole 9 is the bubble vollyball dispensing port of stocking mechanism 1, and when storage bar 11 was positioned at port 8, the bubble vollyball can fall into bypass 5, is delivered to successively connected entrance 7 by bypass connecting gear 6 and prepares to enter main road 3.Can hold a plurality of bubble vollyballs in each storage bar 11, after the bubble vollyball in the storage bar 11 all enters bypass 5, large dial wheel 12 operations change the position of storage bar, the storage bar 11 of sky is seen off, and the storage bar 11 that will have the bubble vollyball is transported to through hole 9, continue to throw in the bubble vollyball, realize the continuous input of bubble vollyball.
More than bubble vollyball automatic filling device provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
