Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a ceramic ice-proof and lightning-proof insulator. Background Technique

[0002] An insulator is a device used to isolate a wire or electrical equipment from a grounded part such as a bracket or a building, so as to prevent current from flowing to places where it should not flow, thereby playing an insulating role. Insulators are usually made of insulating materials such as ceramics and fiberglass-reinforced plastics, and have good insulation performance and mechanical strength, which can effectively prevent current from passing through.

[0003] When inspecting the ceramic shell of some existing insulators, there are easily blind spots in the line of sight. At this time, the operator needs to change his own position. Since the position of the insulator is relatively high, it is rather troublesome for the operator to move the position. Moreover, such insulators are usually set as a whole. When the ceramic shell is damaged, the entire insulator needs to be replaced, resulting in waste of resources.

[0004] Therefore, the technical personnel in this field provide a ceramic ice-proof and lightning-proof insulator to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a ceramic ice-proof and lightning-proof insulator is proposed. By setting a first rotating block and a second rotating block, it is more convenient to inspect the ceramic shell. By setting a pressing plate and a sliding block, when the ceramic shell is damaged, it can be replaced without replacing the entire insulator, reducing waste of resources.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A ceramic ice-proof and lightning-proof insulator, including a fixing mechanism and two protection mechanisms. The fixing mechanism includes a fixing plate, two sliding grooves, two pressing plates, a first rotating block, a core rod, a lower aluminum block, a plurality of annular resistance sheets, an upper aluminum block, an arc-drawing rod, a hand-pulling plate and an extrusion plate. Two first return springs are respectively fixedly arranged between the lower end surfaces of the two pressing plates and the inner bottom surfaces of the two sliding grooves. An annular electrode is fixedly sleeved on the upper side of the outer end surface of the core rod.

[0007] A fixing block is fixedly sleeved on the upper side of the outer end surface of the annular electrode. A second rotating block is rotatably sleeved on the upper side of the outer end surface of the fixing block. An ice-proof cover is fixedly sleeved on the lower side of the outer end surface of the fixing block. Two second return springs are fixedly arranged between the hand-pulling plate and one of the sides of the two sliding grooves. The two protection mechanisms include two ceramic shells, two rubber layers, two arc-shaped grooves and two arc-shaped blocks. Sliding blocks are fixedly arranged at the middle positions of the upper end surfaces of the two arc-shaped blocks.

[0008] Through the above technical solution, by pulling the manual pull plate to one side, the bump at the lower end of the manual pull plate leaves the inner wall of the first rotating block, and the bump at the upper end of the manual pull plate leaves the inner wall of the fixed block. At this time, the ceramic shell can be held and rotated, making it more convenient to inspect the ceramic shell. By manually squeezing the two pressing plates downward, the two L-shaped bumps on the lower end surfaces of the two pressing plates respectively leave the inner walls of the two sliders. At this time, the ceramic shell can be held and moved.

[0009] Further, the two sliding grooves are respectively opened on both sides of the upper end surface of the fixing plate, and the two pressing plates are respectively slidably arranged between the front and rear inner walls of the two sliding grooves on the upper side;

[0010] Through the above technical solution, the pressing plates are limited by the sliding grooves, making the pressing plates more stable when moving.

[0011] Further, the first rotating block is rotatably arranged through the middle position of the upper end surface of the fixing plate, and the lower side of the outer end surface of the core rod is fixedly sleeved on the inner wall of the first rotating block;

[0012] Through the above technical solution, the first rotating block is limited by the fixing plate, so that the first rotating block can only rotate within the inner wall of the fixing plate.

[0013] Further, the lower aluminum block is fixedly sleeved on the lower side of the outer end surface of the core rod, multiple annular resistance sheets are fixedly sleeved on the outer end surface of the core rod, and the upper aluminum block is fixedly sleeved on the upper side of the outer end surface of the core rod;

[0014] Through the above technical solution, these parts together constitute the structure of the insulator, effectively supporting and insulating the power line, ensuring the reliability and safety of power transmission.

[0015] Further, the arc striking rod is fixedly connected to the upper aluminum block, the pressing plate is fixedly connected to the second rotating block through bolts, and the manual pull plate is slidably arranged through the middle position of one side end surface of the fixing plate;

[0016] Through the above technical solution, by rotating the bolt, the wire is placed on the surface of the second rotating block, and then the bolt is rotated again to fix the wire on the surface of the second rotating block.

[0017] Further, the two rubber layers are respectively slidably sleeved on the front and rear positions of the outer end surface of the fixing mechanism, the two rubber layers are respectively fixedly connected to the two ceramic shells, and the two ceramic shells are both clamped to the fixing plate;

[0018] Through the above technical solution, when squeezing the two pressing plates, the clamping of the two sliders is released, and at this time, the two ceramic shells can be removed.

[0019] Furthermore, the two arc-shaped grooves are respectively formed in the lower sides of the outer end faces of the two ceramic housings, and the two arc-shaped blocks are respectively slidably arranged on the inner bottom surfaces of the two arc-shaped grooves;

[0020] Through the above technical solution, the slider is connected to the ceramic housing by fixedly connecting the arc-shaped block to the slider, and the slider can slide inside the ceramic housing.

[0021] The utility model has the following beneficial effects:

[0022] 1. For a ceramic anti-icing and lightning protection insulator proposed by the utility model, by manually pulling the hand-pulling plate to one side, the cylinder on the lower side of the hand-pulling plate leaves the inner wall of the first rotating block, releasing the clamping of the fixing plate on the first rotating block, and the cylinder on the upper side of the hand-pulling plate leaves the inner wall of the fixing block, releasing the clamping of the fixing block on the second rotating block. At this time, the hand-pulling plate can be continuously pulled while holding the ceramic housing to rotate, facilitating the observation of the dead corners of the ceramic housing.

[0023] 2. For a ceramic anti-icing and lightning protection insulator proposed by the utility model, by pressing down the two pressing plates, the two pressing plates drive the L-shaped convex blocks on the lower end faces to move downward together, so that the L-shaped convex blocks do not abut against the inner wall of the slider. At this time, the front ceramic housing can be held and moved, and then the rear ceramic housing can be removed, facilitating the maintenance of the internal parts. And when the ceramic housing is damaged, it is not necessary to replace the entire insulator, reducing the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Implementation Manner

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to Figure 1-8 , an embodiment provided by the present invention: A ceramic anti-icing and lightning protection insulator includes a fixing mechanism 1 and two protection mechanisms 2. The fixing mechanism 1 includes a fixed plate 101, two sliding grooves 102, two pressing plates 103, a first rotating block 106, a mandrel 107, a lower aluminum block 108, a plurality of ring-shaped resistance sheets 109, an upper aluminum block 110, an arc ignition rod 111, a hand-pulling plate 112, and an extrusion plate 117. An upper side of an outer end surface of the mandrel 107 is fixedly sleeved with a ring-shaped electrode 113. An upper side of an outer end surface of the ring-shaped electrode 113 is fixedly sleeved with a fixed block 114. An upper side of an outer end surface of the fixed block 114 is rotatably sleeved with a second rotating block 115. A lower side of an outer end surface of the fixed block 114 is fixedly sleeved with an anti-icing cover 116. The lower aluminum block 108 is fixedly sleeved on a lower side of the outer end surface of the mandrel 107. A plurality of ring-shaped resistance sheets 109 are all fixedly sleeved on the outer end surface of the mandrel 107. The upper aluminum block 110 is fixedly sleeved on an upper side of the outer end surface of the mandrel 107. The arc ignition rod 111 is fixedly connected to the upper aluminum block 110. The extrusion plate 117 is fixedly connected to the second rotating block 115 by bolts.

[0036] By rotating two bolts and then passing one end of the wire through the lower end of the pressing plate 117, when the wire is placed on the surface of the second rotating block 115, rotating the bolts again can fix the wire on the surface of the second rotating block 115. When the wire is fixed and the insulator is in use, these parts together constitute the structure of the insulator, effectively supporting and insulating the power line, ensuring the reliability and safety of power transmission. By setting the ceramic shell 201 and the anti-icing cover 116, the internal parts can be protected from being damaged by ice and snow. By setting the ceramic shell 201 and the rubber layer 202, the internal parts can be further protected from being damaged by lightning.

[0037] Two first return springs 104 are respectively fixedly arranged between the lower end surfaces of the two pressing plates 103 and the inner bottom surfaces of the two sliding grooves 102. The two sliding grooves 102 are respectively opened on both sides of the upper end surface of the fixing plate 101. The two pressing plates 103 are respectively slidably arranged between the front and rear inner walls of the two sliding grooves 102 on the upper side. The two rubber layers 202 are respectively slidably sleeved on the front and rear positions of the outer end surface of the fixing mechanism 1. The two rubber layers 202 are respectively fixedly connected to the two ceramic shells 201. The two ceramic shells 201 are both clamped to the fixing plate 101. Two arc grooves 203 are respectively opened on the lower sides of the outer end surfaces of the two ceramic shells 201. Two arc blocks 204 are respectively slidably arranged on the inner bottom surfaces of the two arc grooves 203.

[0038] By manually squeezing the two pressing plates 103 downward, the two L-shaped convex blocks on the lower end surfaces of the two pressing plates 103 respectively leave the inner walls of the two sliders 205, so that they no longer abut against the inner walls of the sliders 205. At this time, the front ceramic shell 201 can be held and moved, and then the rear ceramic shell 201 can be moved. When moving the two ceramic shells 201, the two pressing plates 103 need to be continuously squeezed. When the pressing plates 103 are not squeezed, the return force of the first return spring 104 provides an upward force to the pressing plates 103, and the L-shaped convex blocks can be fixed in the inner walls of the sliders 205. At this time, the two ceramic shells 201 can be clamped to the fixing plate 101 together.

[0039] Two second return springs 105 are fixedly arranged between the hand pull plate 112 and one of the sides of the two sliding grooves 102. The two protection mechanisms 2 include two ceramic shells 201, two rubber layers 202, two arc grooves 203 and two arc blocks 204. At the middle positions of the upper end faces of the two arc blocks 204, sliders 205 are fixedly arranged. The hand pull plate 112 is slidably arranged through the middle position of one side end face of the fixed plate 101. By pulling the hand pull plate 112 to one side, the convex block at the lower end of the hand pull plate 112 leaves the inner wall of the first rotating block 106, and the convex block at the upper end of the hand pull plate 112 leaves the inner wall of the fixed block 114. At this time, the ceramic shell 201 can be held and rotated. When rotating the ceramic shell 201, the slider 205 and the arc block 204 are fixed inside the ceramic shell 201 by being clamped with the fixed plate 101. And when rotating the ceramic shell 201, the second rotating block 115 will not rotate, so that the wire remains in its original position and there is no need to remove the wire first.

[0040] Working principle: When repairing the ceramic shell 201, while pulling the hand pull plate 112 to one side, hold the ceramic shell 201 and rotate it. When pulling the hand pull plate 112, the cylinder at the lower side of the hand pull plate 112 leaves the inner wall of the first rotating block 106, and the cylinder at the upper side of the hand pull plate 112 leaves the inner wall of the fixed block 114. When it is necessary to replace the ceramic shell 201 or repair the inside, while pressing the pressing plate 103 downward, hold the ceramic shell 201 and move it. When pressing the pressing plate 103, the L-shaped convex block on the surface of the pressing plate 103 leaves the inner wall of the slider 205, thereby releasing the clamping of the two ceramic shells 201.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
