Description

Technical Field

[0001] The present application relates to the field of electric power technology, and in particular to a sheath and a 10kV insulating operating rod. Background Art

[0002] The existing 10kv insulated operating rods are about 1.5 meters long each, and are available in two types: hollow and solid. The surface of each section is round, smooth, and coated with varnish. Each section of the operating rod is connected by threads. The main materials of the rod body are epoxy resin and glass fiber, and the main materials of the connecting parts are stainless steel. The 10kv insulated operating rod used in rainy days will also be equipped with a rain cover.

[0003] After research, it was found that the existing 10kv insulated operating rod has the following shortcomings:

[0004] 1. Because the surfaces of each section of the operating rod are round and coated with smooth insulating varnish, when the operator wears insulating gloves and performs twisting operations, he needs to increase the grip of his hands to maintain a certain friction force to provide sufficient torque, which makes the operator's hand muscles easily fatigued and weak. When overhead electrical equipment ages and rusts, the operator fatigue is more serious.

[0005] 2. When the operating rod is exposed to moisture, the internal glass fiber is easily hydrolyzed, resulting in a decrease in the insulation performance of the operating rod, posing a personal safety risk of electric shock.

[0006] Therefore, it is urgent to provide a solution to solve the above problems. Summary of the invention

[0007] In view of this, the purpose of the present application is to provide a sheath and a 10kV insulating operating rod to solve the technical problems of the existing 10kv insulating operating rod, such as the difficulty in operation and the risk of electric shock due to moisture.

[0008] In order to achieve the above technical purpose, the present application provides a sheath, including an insulating sheath body and a fastener;

[0009] The sheath body is in the shape of a polygonal column, and the two ends of the axis are connected;

[0010] Both ends of the sheath body are provided with cylindrical fixing tubes extending outwards;

[0011] The fixing tube and the sheath body are coaxial;

[0012] The outer circumferential surface of the fixing tube is provided with at least two openings parallel to its own axis, so that the fixing tube forms at least two clamping parts in its own circumferential direction;

[0013] An external thread structure is provided on the outer peripheral surface of the clamping portion;

[0014] There are two fasteners, which are connected to the two fixing tubes in a one-to-one correspondence;

[0015] The two ends of the axis of the fastener are connected;

[0016] The diameter of the axial channel of the fastener gradually decreases from one end to the other end, and is provided with an internal thread structure threadedly connected to the external thread structure.

[0017] Furthermore, the sheath body is in the shape of a triangular prism.

[0018] Furthermore, the inner circumferential surface of the clamping portion is provided with a first anti-slip structure.

[0019] Furthermore, a second anti-slip structure is provided on the outer peripheral surface of the sheath body.

[0020] Furthermore, the first anti-slip structure and the second anti-slip structure are both frosted structures.

[0021] Furthermore, a third anti-slip structure is provided on the outer peripheral surface of the fastener.

[0022] Furthermore, a plurality of vertical protrusions are circumferentially arrayed on the outer circumferential surface of the fastener and protrude outward in the radial direction of the fastener to form the third anti-slip structure.

[0023] Furthermore, the fastener is in the shape of a truncated cone.

[0024] Furthermore, the sheath body is made of composite inorganic material.

[0025] The present application also discloses a 10kV insulating operating rod, comprising an operating rod body and at least one of the aforementioned sheaths;

[0026] The sheath body of the sheath is sleeved on the operating rod body;

[0027] The fasteners of the sheath are sleeved on the fixing tubes at both ends of the operating rod body;

[0028] The fastener is threadedly connected to the fixing tube, so that the clamping portion on the fixing tube clamps the operating rod body.

[0029] It can be seen from the above technical solutions that the sheath designed in this application has the following beneficial effects:

[0030] 1. After the sheath designed in this application is fixed on the operating rod, the shape of the operating rod grip can be changed (to achieve a non-circular grip), the torque when the operating rod is twisted can be increased, and the twisting operation can be labor-saving. By increasing the friction coefficient of the operating rod grip, the friction force during gripping is increased, and the possibility of slipping during twisting operation due to wearing insulating gloves is reduced.

[0031] 2. After the sheath designed in the present application is fixed on the operating rod, an additional layer of insulating material protection can be added to the handle of the operating rod, further reducing the risk of electric shock due to reduced insulation performance caused by moisture on the operating rod.

[0032] 3. The sheath body and fasteners in the sheath are detachable and can be used directly on the existing operating rod, saving storage space. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The embodiment of the present application discloses a sheath.

[0041] See also Figure 1 , an embodiment of a sheath provided in the embodiments of the present application includes:

[0042] Insulating sheath body 1 and fastener 3.

[0043] The sheath body 1 is in the shape of a polygonal column, and the two ends of the axis are connected to form an axis channel for the operating rod to pass through (the diameter of the axis channel is slightly larger than the outer diameter of the corresponding operating rod to ensure that the sheath body 1 can move freely on the operating rod).

[0044] The length of the sheath body 1 can be varied according to actual needs, for example, it can be designed to be 1 meter. In addition, the edges on the outer surface of the sheath body 1 can be designed with rounded transitions to increase the comfort of holding.

[0045] The multi-prism design can change the shape of the handle of the operating lever (to achieve a non-circular grip) and increase the torque when the operating lever is twisted.

[0046] The two ends of the sheath body 1 are extended outwardly with cylindrical fixing tubes 2, and the fixing tube 2 and the sheath body 1 are coaxial; the fixing tube 2 and the sheath body 1 can be integrally formed, and the fastener 3 can be made of the same insulating material as the sheath body 1.

[0047] At least two openings 21 parallel to the axis of the fixing tube 2 are formed on the outer circumference of the fixing tube 2 , so that the fixing tube 2 forms at least two clamping parts 22 in its circumference; an external thread structure 23 is provided on the outer circumference of the clamping part 22 .

[0048] There are two fasteners 3, which are connected to the two fixing tubes 2 one by one; the two ends of the axis of the fastener 3 are connected (the diameter of the axis channel of the fastener 3 is slightly larger than the outer diameter of the corresponding operating rod to ensure free movement and rotation on the operating rod).

[0049] The diameter of the axial channel of the fastener 3 gradually decreases from one end to the other end, and is provided with an internal thread structure 31 threadedly connected to the external thread structure 23 .

[0050] The design of opening 21 on the outer peripheral surface of the fixing tube 2 facilitates the contraction of the fixing tube 2 after the fastener 3 is tightened (as the threaded connection fastener 3 is tightened, the fixing tube 2 of the sheath body 1 will gradually contract), and the multi-petal clamping portion 22 on the fixing tube 2 can clamp and fix the operating rod, so that the fixing tube 2 is fixed on the operating rod, thereby fixing the sheath body 1.

[0051] The sheath designed in this application has the following beneficial effects:

[0052] 1. After the sheath designed in this application is fixed on the operating rod, the shape of the operating rod grip can be changed (to achieve a non-circular grip), the torque when the operating rod is twisted can be increased, and the twisting operation can be labor-saving. By increasing the friction coefficient of the operating rod grip, the friction force during gripping is increased, and the possibility of slipping during twisting operation due to wearing insulating gloves is reduced.

[0053] 2. After the sheath designed in the present application is fixed on the operating rod, an additional layer of insulating material protection can be added to the handle of the operating rod, further reducing the risk of electric shock due to reduced insulation performance caused by moisture on the operating rod.

[0054] 3. The sheath body 1 and the fastener 3 in the sheath are detachable and can be directly used on the existing operating rod, thus saving storage space.

[0055] The above is an embodiment 1 of a sheath provided in the embodiment of the present application. The following is an embodiment 2 of a sheath provided in the embodiment of the present application. For details, please refer to Figure 1 .

[0056] Based on the solution of the above embodiment 1:

[0057] Furthermore, the sheath body 1 is preferably in the shape of a triangular prism with a triangular cross section, and may also be designed to be in the shape of a quadrangular prism, a pentagonal prism, etc. as required.

[0058] Furthermore, the inner circumferential surface of the clamping portion 22 is provided with a first anti-slip structure to increase the contact friction between the clamping portion 22 and the operating rod, thereby improving the reliability of the clamping fixation.

[0059] Furthermore, a second anti-slip structure is provided on the outer peripheral surface of the sheath body 1 to increase the gripping friction and improve the convenience of the gripping operation.

[0060] Furthermore, the first anti-slip structure and the second anti-slip structure are both frosted structures. Of course, other anti-slip structure designs are also possible. The specific design is changed according to actual needs without limitation.

[0061] Furthermore, a third anti-slip structure is provided on the outer peripheral surface of the fastener 3 to increase the friction force during twisting, so as to facilitate the operation of rotating the fastener 3.

[0062] Furthermore, a plurality of vertical protrusions 32 protruding radially outward from the fastener 3 are circumferentially arrayed on the outer peripheral surface of the fastener 3 to form a third anti-slip structure. Of course, other anti-slip structure designs are also possible, and the specific design is changed according to actual needs without limitation.

[0063] Furthermore, the fastener 3 is preferably in a truncated cone shape, the bottom of the cone is regarded as the bottom of the fastener 3, the top of the cone is regarded as the top of the fastener 3, and the diameter of the axial channel of the fastener 3 gradually decreases from the bottom to the top.

[0064] Furthermore, the sheath body 1 is made of a composite inorganic material, which reduces the risk of electric shock caused by surface flashover when using the operating rod in rainy weather.

[0065] Furthermore, there are three openings 21, correspondingly forming a three-petal clamping portion 22, and the specific number can be designed according to actual needs without limitation.

[0066] like Figure 2 As shown, the present application also discloses a 10kV insulating operating rod, including an operating rod body 4 and at least one sheath.

[0067] The sheath body 1 of the sheath is sleeved on the operating rod body; the fastener 3 of the sheath is sleeved on the fixing tubes 2 at both ends of the operating rod body; the fastener 3 is threadedly connected to the fixing tube 2 so that the clamping part 22 on the fixing tube 2 forms a clamp on the operating rod body.

[0068] When in use, first insert the top of the first fastener 3 into the operating rod body 4, then insert the sheath body 1 into the operating rod body 4, tighten the first fastener 3 and the fixing tube 2 at the top of the sheath body 1, fix the sheath body 1 in a suitable position, and finally insert the second fastener 3 into the operating rod body 4 and tighten it on the fixing tube 2 at the bottom of the sheath body 1.

[0069] In addition, when in use, one sheath may be used for each section of the operating rod body 4, or the corresponding operating rod body 4 may be used as required, without limitation.

[0070] The above is a detailed introduction to a sheath and a 10kV insulating operating rod provided by the present application. For a general technician in this field, according to the idea of ​​the embodiments of the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
