Description
Technical Field
[0001] The utility model relates to the technical field of composite insulators, in particular to a composite insulator with a protection structure. Background Art
[0002] Insulators are usually made of ceramic or glass. In today's society, there are more and more transmission lines and people pay more and more attention to power management. Insulators are an indispensable device on transmission lines. Insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground.
[0003] For example, the utility model with announcement number CN210073481U discloses a composite insulator with a self-protection function. By setting a movable sleeve block and fan blades, when the natural wind from the outside blows the fan blades, the fan blades will drive the movable sleeve block to rotate, thereby effectively preventing small birds from staying on the top of the first insulating umbrella sleeve and the second insulating umbrella sleeve, preventing small birds from pecking at the first insulating umbrella sleeve and the second insulating umbrella sleeve, thereby improving the self-protection ability of the composite insulator and thus increasing the practicality of the composite insulator.
[0004] However, since insulators are often used at high altitudes, and in good weather conditions, the fan blades are not always blown by natural wind, resulting in the insulators being exposed to wind and sun all year round, causing the sheds to often be covered with dust, which greatly reduces their service life. Therefore, a composite insulator with a protective structure is proposed to solve the above problem. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a composite insulator with a protective structure, which has the advantages of improving the protective effect and solves the problem of poor protective effect.
[0006] To achieve the above object, the utility model provides the following technical solutions: a composite insulator with a protective structure, comprising a core column and an shed fixed to the outside of the core column, the end of the core column is provided with a mounting bolt, and the outside of the core column is provided with a protective component located outside the shed;
[0007] The protection component includes a mounting sleeve mounted on the outside of the core column, the end of the mounting sleeve is fixedly connected to the protection sleeve located on the outside of the umbrella skirt, a reflective strip is arranged on the outside of the protection sleeve, the outside of the mounting sleeve is slidably connected to a fixing ring, the outside of the mounting sleeve is fixedly connected to a retaining ring whose end is fitted with the fixing ring, the outside of the fixing ring is slidably connected to a limiting rod whose end passes through and extends into the inside of the mounting sleeve, and a support spring is fixedly connected between one end of the limiting rod located on the outside of the fixing ring and the outside of the fixing ring.
[0008] Furthermore, one end and the other end of the core column are both provided with mounting grooves, and the mounting screws penetrate the mounting grooves of the core column and are fixed to the ends of the core column.
[0009] Furthermore, the inner diameter of the fixing ring is matched with the outer diameter of the mounting sleeve, the specifications of the inner side of the protective sleeve are matched with the specifications of the outer side of the umbrella skirt, and the number of the reflective strips is several, and the several reflective strips are distributed on the protective sleeve in a circular shape and at equal intervals.
[0010] Furthermore, there are a plurality of the installation sleeves and protective sleeves, and the plurality of the installation sleeves and protective sleeves are fixedly connected end to end in sequence from top to bottom.
[0011] Furthermore, each of the installation sleeve and the protective sleeve is composed of two semicircular sleeves, and the two semicircular sleeves are symmetrically distributed on the outside of the core column and the umbrella skirt.
[0012] Furthermore, a fixing groove located outside the limiting rod is provided on the outer side of the installation sleeve, and one end of the limiting rod located inside the fixing groove is inclined.
[0013] Furthermore, there are two limit rods, which are symmetrically distributed on the fixing ring. One end of the limit rod away from the fixing ring is T-shaped, and the support spring is fixedly connected between the T-end of the limit rod and the fixing ring.
[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0015] 1. The composite insulator with a protective structure can cover the core column and the shed because the installation sleeve and the protective sleeve are located on the outside of the core column and the shed, reducing the possibility of dust and rainwater eroding the shed and the core column. The reflective strip located on the outside of the protective sleeve makes birds feel uncomfortable when they see the strong light reflected by the reflective strip, so they stay away from this area, thereby achieving the effect of driving away birds and improving the protective effect of the composite insulator.
[0016] 2. For the composite insulator with a protective structure, since the installation sleeve is fixed by the limit rod on the fixing ring, when the maintenance personnel need to remove or replace the installation sleeve and the protective sleeve, they only need to pull the limit rod to drive the fixing ring and the installation sleeve to separate, and then the installation sleeve and the protective sleeve can be removed, which increases the convenience of disassembly and assembly, reduces the operator's high-altitude working time, and improves construction safety.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 In this embodiment, a composite insulator with a protective structure includes a core column 1 and an shed 2 fixed to the outside of the core column 1, a mounting bolt 3 is provided at the end of the core column 1, and a protective component 4 located outside the shed 2 is provided on the outside of the core column 1;
[0024] The protection assembly 4 comprises a mounting sleeve 41 which is sleeved on the outside of the core column 1, and the end of the mounting sleeve 41 is fixedly connected to a protection sleeve 42 which is located on the outside of the shed 2.
[0025] In this embodiment, the core column 1 and the umbrella skirt 2 are covered by the cooperation of the installation sleeve 41 and the protective sleeve 42, thereby reducing the possibility of dust and rainwater erosion of the umbrella skirt 2 and the core column 1. The reflective strip 43 located on the outside of the protective sleeve 42 makes birds feel uncomfortable when they see the strong light reflected by the reflective strip, and thus stay away from this area, thereby achieving the effect of driving away birds.
[0026] Among them, one end and the other end of the core column 1 are both provided with mounting grooves, and the mounting screw 3 passes through the mounting groove of the core column 1 and is fixed to the end of the core column 1.
[0027] In addition, there are several mounting sleeves 41 and protective sleeves 42 , which are fixedly connected end to end from top to bottom, and the number of mounting sleeves 41 and protective sleeves 42 can be set according to the length of the core column 1 and the number of umbrella skirts 2 .
[0028] Secondly, each installation sleeve 41 and protective sleeve 42 is composed of two semicircular sleeves, which are symmetrically distributed on the outside of the core column 1 and the umbrella skirt 2, so that the installation sleeve 41 and the protective sleeve 42 fit and cover the outside of the core column 1 and the umbrella skirt 2 on the left and right.
[0029] See also Figure 2-4 In this embodiment, a fixing ring 44 is slidably connected to the outer side of the mounting sleeve 41, a retaining ring 45 is fixedly connected to the outer side of the mounting sleeve 41 and one end of the retaining ring 45 is in contact with the fixing ring 44, and a limiting rod 47 is slidably connected to the outer side of the fixing ring 44 and one end of the limiting rod 47 passes through and extends to the inside of the mounting sleeve 41, and a support spring 46 is fixedly connected between one end of the limiting rod 47 located on the outer side of the fixing ring 44 and the outer side of the fixing ring 44.
[0030] In this embodiment, when the maintenance personnel need to remove or replace the installation sleeve 41 and the protective sleeve 42, they only need to pull the limit rod 47 to drive the fixing ring 44 to separate from the installation sleeve 41, and then the installation sleeve 41 and the protective sleeve 42 can be removed, thereby increasing the convenience of disassembly and assembly and reducing the operator's high-altitude working time.
[0031] Among them, the inner diameter of the fixing ring 44 is adapted to the outer diameter of the mounting sleeve 41, the specifications of the inner side of the protective sleeve 42 are adapted to the specifications of the outer side of the umbrella skirt 2, the number of reflective strips 43 is several, and the several reflective strips 43 are evenly distributed on the protective sleeve 42 in a circular shape, and birds are driven away by the several reflective strips 43 evenly distributed in a circular shape.
[0032] In addition, a fixing groove 48 is provided on the outside of the mounting sleeve 41 and is located on the outside of the limiting rod 47. One end of the limiting rod 47 located on the inside of the fixing groove 48 is inclined, so that when the fixing ring 44 slides to the outside of the mounting sleeve 41 and fits with the retaining ring 45, the inclined end of the limiting rod 47 can be squeezed into the fixing groove.
[0033] Secondly, there are two limit rods 47, which are symmetrically distributed on the fixing ring 44. The end of the limit rod 47 away from the fixing ring 44 is T-shaped, and the support spring 46 is fixedly connected between the T-end of the limit rod 47 and the fixing ring 44. The fixing ring 44 is stably limited and fixed by the two limit rods 47 on each fixing ring 44.
[0034] The working principle of the above embodiment is:
[0035] Since the installation sleeve 41 and the protective sleeve 42 are located on the outside of the core column 1 and the umbrella skirt 2, they can cover the core column 1 and the umbrella skirt 2, reducing the possibility of dust and rainwater eroding the umbrella skirt 2 and the core column 1. The reflective strip 43 located on the outside of the protective sleeve 42 makes birds feel uncomfortable when they see the strong light reflected by the reflective strip, and thus stay away from this area, thereby playing a bird-repelling effect and improving the protection effect of the composite insulator. Since the installation sleeve 41 is fixed by the limit rod 47 on the fixing ring 44, when the maintenance personnel need to remove or replace the installation sleeve 41 and the protective sleeve 42, they only need to pull the limit rod 47 to drive the fixing ring 44 to separate from the installation sleeve 41, and then the installation sleeve 41 and the protective sleeve 42 can be removed, thereby increasing the convenience of disassembly and assembly, reducing the operator's high-altitude operation time, and improving construction safety.
