Description

A kind of pipe expansion grid

Technical field

The utility model relates to technical field of aquaculture, especially a kind of pipe expansion grid.

Background technique

It can be laid in aquaculture field, aquaculture pond compared with multi-pipeline, be used with making to supply water or drain.Supporting in aquaculture pond Growing object may enter in pipeline with water flow, on the one hand may cause material culture escape, reduce cultivation quantity, on the other hand, Material culture may block pipeline, influence normally to supply water or drain.

In the prior art, it will usually filter screen is installed additional in nozzle, to prevent material culture from entering in pipeline.But this mistake Strainer needs to be fixed in nozzle by modes such as welding, brings inconvenience to the installation and removal of filter screen.

Utility model content

The utility model provides a kind of pipe expansion grid, is fixed in pipeline by the fixed form of expansion clamping, side Just it mounts and dismounts.

A kind of pipe expansion grid, the expansion loop including elastically deformable, the inside of the expansion loop are equipped with multiple to swollen The top of the fixed link that tensioner ring axle center extends, the fixed link is equipped with expansion-head；Pre- spacing is spaced between two neighboring expansion-head Expansion hole is enclosed in expansion loop axle center from, all expansion-heads, it is detachable in the expansion hole to be fixed with expansion piece, it is described Expansion piece is for strutting the expansion-head, to increase the radius of expansion loop.

Preferably, the expansion loop is composed of multiple separately positioned expansion arc bands, two neighboring expansion arc band logical Connector is crossed to be connected and fixed.

Preferably, two fixed links and the same expansion-head stationary phase being separately positioned on two neighboring expansion arc band Even, to form the connector.

Preferably, the expansion arc band and expansion-head are uniformly and symmetrically distributed centered on expansion loop axle center.

Preferably, the inner wall of the expansion hole is equipped with screw thread, and the expansion piece is the screw to match with the screw thread.

Preferably, filter hole is formed between adjacent two fixed links.

In the utility model, expansion piece can be fixed in expansion hole, strut all expansion-heads, and then increase the half of expansion loop Diameter, expansion loop can clamping fixed in pipeline.Due to expansion piece be it is detachable be fixed in expansion hole, can be according to needs It installs or removes at any time, it is more convenient to use.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the pipe expansion grid of embodiment of the utility model.

Specific embodiment

The utility model is described in further detail below by specific embodiment combination attached drawing.

The utility model embodiment provides a kind of pipe expansion grid, as shown in Figure 1, including the expansion loop of elastically deformable 1, expansion loop 1 is enclosed a cyclic structure, can be made of the material of the elastically deformables such as plastic cement.The expansion loop 1 inside is equipped with multiple fixed links 2 extended to the axle center of expansion loop 1, and more fixed links 2 are centered on the axle center of expansion loop 1 Radially it is distributed, it is spaced apart between adjacent two fixed links 2, to form filtering between adjacent two fixed links 2 Hole 20, the size of filter hole 20 flow through, material culture can not pass through according to actual needs setting for water.

The top of fixed link 2, i.e., the one end extended to 1 axle center of expansion loop are equipped with expansion-head 3, and every fixed link 2 can be distinguished One expansion-head 3 is set, alternatively, an expansion-head 3 can be connected and fixed more fixed links 2.Two neighboring expansion-head 3 does not connect each other Touching, and be spaced a predetermined distance, all expansion-heads 3 are enclosed an expansion hole 30 in the axle center of expansion loop 1.The expansion hole 30 It is interior it is detachable be fixed with expansion piece, the radius of expansion piece is slightly larger than the radius of expansion hole 30.When expansion piece is fixed on expansion hole In 30, due to 1 elastically deformable of expansion loop, all expansion pieces 3 will be softened, and then increase the radius of expansion loop 1, expansion loop 1 can clamping fixed on the inner wall of pipeline.Since expansion piece uses detachable fixed structure, entire grid can be facilitated to obtain Installation and removal.

In one embodiment, the expansion loop 1 is composed of multiple separately positioned expansion arc bands 11, two neighboring It is spaced apart between expansion arc band 11, during expansion piece is fixed on expansion hole 30, two neighboring expansion arc band 11 Between spacing will increase, due to expansion arc band 11 between be it is separately positioned, be equivalent to and enhance the elastic deformation of expansion loop 1 Power increases fixed effect of the expansion grid in pipeline.Certainly, in order to guarantee that expansion loop 1 has certain structure strong Degree, two neighboring expansion arc band 11 are connected and fixed by connector.

Specifically, two fixed links 2 and the same expansion-head 3 that are separately positioned on two neighboring expansion arc band 11 are fixed It is connected, in this way, two fixed links 2 and the expansion-head 3 being attached thereto form the connector, to connect two neighboring expansion arc band 11。

Wherein, the expansion arc band 11 and expansion-head 3 are uniformly and symmetrically distributed centered on the axle center of expansion loop 1, are guaranteed Expansive force is uniformly distributed on the circumferential surface of expansion loop 1.

In one embodiment, the inner wall of the expansion hole 30 is equipped with screw thread, i.e. the inside of expansion-head 3 is equipped with screw thread, institute Stating expansion piece is the screw to match with the screw thread, realizes detachable fixation by the cooperation of screw and screw thread.

The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field For, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made.
