Technical Field

The disclosure relates to the technical field of power transmission, in particular to an anti-loosening drainage device.

Background

According to the design and operation requirements of the power transmission line, strain towers are required to be arranged at intervals, and the conducting wires are cut off at the positions of the strain towers, so that the length of the line along the longitudinal continuous gear is reduced, the construction and the maintenance are convenient, and the range of the line possibly falling along the longitudinal tower is controlled. The front and back disconnected wires of the strain tower are electrically connected through the connecting hardware fitting and the drainage plate, and the through-flow requirement is met.

The inventor finds in research that in daily operation and maintenance work, the drainage plate often has a fault of heating caused by poor contact due to bolt loosening, and therefore how to prevent the drainage plate from loosening is a problem to be solved urgently by power transmission technicians.

SUMMERY OF THE UTILITY MODEL

The purpose of this description embodiment is to provide locking type drainage device that takes off, adopts draw-in groove formula mounting structure, reduces installation accessory quantity, reduces because of the not hard up probability that causes the contact surface to break away from of bolt.

The embodiment of the specification provides an anti-loosening drainage device, which is realized by the following technical scheme:

the method comprises the following steps: a first drainage plate and a second drainage plate;

the first drainage plate and the second drainage plate respectively comprise a circular cavity and a convex-concave groove structure arranged at one end of the circular cavity;

the first drainage plate and the second drainage plate are clamped and connected through the convex-concave groove structure;

the convex-concave groove structures of the first drainage plate and the second drainage plate are fixed by bolts after being clamped.

According to the further technical scheme, one end of each of the circular cavities of the first drainage plate and the second drainage plate is open, and the other end of each of the circular cavities is of a conical structure.

According to the further technical scheme, the wire penetrates into the circular cavity in the first drainage plate and is pressed in the circular cavity.

According to the technical scheme, the grooves of the first drainage plate and the convex grooves of the second drainage plate are clamped and fixed through bolts.

According to the further technical scheme, the convex groove of the first drainage plate and the groove of the second drainage plate are clamped and fixed through a bolt.

Compared with the prior art, the beneficial effect of this disclosure is:

this openly combines current drainage plate bolted connection form, designs a brand-new butt joint face structure, reduces because of the not hard up probability that causes the contact surface to break away from of bolt.

This open draw-in groove formula mounting structure reduces installation accessory quantity, can avoid causing two contact surfaces of AB to break away from because of the bolt is not hard up to reduce the risk that the drainage plate generates heat.

This openly adopts the bolt mounting form, and is the same with current drainage mounting form, and the accessory is few, and the installation is simple swift.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

Example of implementation 1

The embodiment discloses an anti-loosening drainage device, which comprises A, B parts, wherein part A is shown in the accompanying drawings 1(a) -1 (b), one end of part A is a first circular cavity 1, one end of the circular cavity is a first groove 2 and first tongue 3 structure, and the whole part A is a bent structure.

The A is pressed on the wire in a mode that the wire penetrates into the round cavity of the A and is pressed by a hydraulic machine to be in close contact with the wire, so that the force bearing and flow guiding effects are achieved, grooves and convex grooves are prefabricated on the contact surface of the drainage plate of the A, and the groove can be tightly clamped in the second protrusion 6 and the second groove 5 of the drainage plate B in a screwed manner.

A drainage plate: one electric power fitting is used for a tension-resistant tower of a power transmission line and realizes effective contact between a lead and a drainage wire.

The structure of part B is shown in the attached drawings 2(a) -2 (B), the part B is pressed on the lead in a connecting mode that the drainage wire penetrates into a second round cavity 4 of the part B and is pressed by a hydraulic press to be tightly contacted with the lead to achieve partial force bearing and flow guiding effects, a second groove 5 and a second bulge 6 are prefabricated on the contact surface of the drainage plate of the part B, and the contact surface can be tightly screwed and sewed in the first bulge 3 and the first groove 2 of the drainage plate A.

The connection diagram of A and B is shown in detail in FIG. 3:

the contact surfaces A and B are coated with conductive grease, inserted into the bolt holes from the side surfaces and fastened by penetrating two bolts (two fastening bolts respectively comprise two gaskets and one spring sheet).

In the embodiment of the disclosure, the lead and the steel anchor penetrate into the cavity A and are connected together by compression joint to achieve the functions of bearing and guiding, and the steel anchor is connected with the cross arm of the tower by the hardware fitting and the insulator to play a role of bearing; the drainage wire penetrates into the cavity B and achieves certain bearing effect and flow guiding effect after being pressed and connected.

This open embodiment's draw-in groove formula mounting structure can avoid causing two contact surfaces of AB to break away from because of the bolt is not hard up to reduce the risk that the drainage plate generates heat.

The bolt installation form is adopted in the disclosed embodiment, and is the same as the existing drainage installation form, and the installation is simple and fast with few accessories.
