Description

Technical Field

[0001] The utility model relates to a damping protection pad for a spacer, belonging to the technical field of power transmission. Background Art

[0002] A spacer is an indispensable tool in the field of power transmission. The function of the spacer is to separate multiple co-directional cable lines. The current spacer structure includes a spacer body, which is a hollow quadrilateral structure. A hook is provided at each of the four top corners of the spacer body. When in use, the cable line is fixed in the hook, so as to separate the cable lines. For this kind of spacer structure, when the cable line sways due to the blowing of the wind, relative sliding occurs between the cable line and the hook of the spacer. Over time, both the cable line and the spacer may be worn, especially the cable line may break, resulting in a risk to the safety of power transmission.

[0003] To solve the problem of wear between the spacer and the cable line, the Chinese utility model patent with the authorization announcement number CN214543537U discloses a damping protection pad for a polyalloy silicon spacer, which includes a protection pad body and two rows of limiting blocks. The protection pad body is made of rubber material. The two rows of limiting blocks are symmetrically arranged on the same surface of the protection pad body. Each row of limiting blocks includes multiple spaced limiting block units. In the use state, the protection pad body is bent and deformed and installed in the hook of the spacer and cooperates with the hook of the spacer. The limiting block unit is used to cooperate with the limiting groove in the hook of the spacer to prevent the protection pad body from moving in the hook of the spacer. The smooth surface of the protection pad body is used to wrap the cable line.

[0004] The damping protection pad for the spacer disclosed in the above patent has the following defects: in the use state, the protection pad body wraps the cable line. In case of rain, rainwater drops between the protection pad body and the cable line and is difficult to drain. Moreover, the cable line itself generates heat when it is energized. The part where the cable line contacts the protection pad body is not conducive to the heat dissipation of the cable line due to the wrapping of the protection pad body, which affects the service life of the cable line and the protection pad. Summary of the Invention

[0005] The purpose of the utility model is to provide a damping protection pad for a spacer, which solves the technical defects that the damping protection pad for the spacer in the prior art has poor drainage in rainy days and is not conducive to the heat dissipation of the part where the cable line contacts the protection pad.

[0006] To solve the above problems, the technical solution adopted by the present utility model is as follows: A damping protection pad for a spacer, comprising a protection pad body made of rubber material and two rows of limiting blocks. The two rows of limiting blocks are symmetrically arranged on both sides of the same surface of the protection pad body. Each row of limiting blocks includes two or more spaced-apart limiting block units. In the use state, the protection pad body bends and deforms toward the side away from the limiting block units and is installed in the hook of the spacer. The limiting block units cooperate with the grooves on both sides of the hook of the spacer in the use state. On the surface of the protection pad body on the side away from the limiting block units, two rows of heat dissipation and drainage grooves are provided. Each row of heat dissipation and drainage grooves includes one or more heat dissipation and drainage groove units. The mutually remote ends of the two rows of heat dissipation and drainage groove units penetrate through the side surface of the protection pad body, and are used to discharge the rainwater between the cable and the protection pad body and the heat dissipation of the cable in the use state.

[0007] As a further improvement of the present utility model, the number of heat dissipation and drainage groove units is equal to the number of limiting block units, and one heat dissipation and drainage groove unit corresponds to the upper part of each limiting block unit. The width of the heat dissipation and drainage groove unit is smaller than the width of the limiting block unit.

[0008] As a further improvement of the present utility model, one heat dissipation and drainage hole is provided between adjacent two limiting block units on the protection pad body. The heat dissipation and drainage hole is used to discharge the rainwater between the cable and the protection pad body and the heat dissipation of the cable in the use state.

[0009] As a further improvement of the present utility model, the height of the limiting block unit at one end of the edge of the protection pad body is greater than that at the other end, and the depth of the heat dissipation and drainage groove at one end of the edge of the protection pad body is greater than that at the other end.

[0010] As a further improvement of the present utility model, the end with a larger depth of the heat dissipation and drainage groove unit extends downward to the limiting block unit, and the inclination angle of the bottom of the heat dissipation and drainage groove unit is equal to the inclination angle of the bottom surface of the limiting block unit.

[0011] As a further improvement of the present utility model, the limiting block unit is made of the same material as the protection pad body and is integrally formed.

[0012] As a further improvement of the present utility model, a gap is left between the opposite ends of the limiting block units of the two rows of limiting blocks, and the opposite ends of the heat dissipation and drainage groove units of the two rows of heat dissipation and drainage grooves are not communicated with each other.

[0013] In summary, the beneficial effects of the present utility model are as follows: 1. By providing a limit block on the protection pad body, the present utility model is fixed to the hook of the spacer through the cooperation of the limit block unit and the groove on the hook of the spacer. The heat dissipation and drainage grooves opened on the protection pad body can smoothly drain the rainwater dripping on the protection pad body on rainy days, reduce the corrosion of the rainwater to the present utility model and the cable, and are beneficial to the heat dissipation of the cable, thereby improving the service life of the cable. 2. In the present invention, the heat dissipation and drainage groove unit corresponds to the limit block unit, which can ensure the overall strength of the present utility model and there will be no parts with a smaller thickness. 3. The present utility model is provided with heat dissipation and drainage holes, which can discharge the rainwater in the part between the two heat dissipation and drainage groove units, which is more beneficial to the drainage and heat dissipation of the present utility model and avoids water accumulation between the cable and the protection pad body. 4. The widths of both ends of the limit block unit in the present utility model are unequal, and its bottom is inclined, and the bottom of the heat dissipation and drainage groove unit is also inclined, which is more beneficial to the discharge of rainwater and the dissipation of heat. 5. The overall strength of the present utility model is high, not easily damaged, and is easily bent and deformed during use, which is convenient to be placed in the hook of the spacer.

[0021] As Figures 1 to 3The damping protection pad for a spacer shown includes a protection pad body 1 made of rubber material and two rows of limiting blocks 2. The two rows of limiting blocks 2 are symmetrically arranged on both sides of the same surface of the protection pad body 1. For example, in this utility model, the two rows of limiting blocks 2 are symmetrically arranged on the left and right sides of the upper surface of the protection pad body 1. Each row of limiting blocks 2 includes more than two spaced-apart limiting block units 3. For example, in this utility model, each row of limiting blocks 2 includes four limiting block units 3, and the four limiting block units 3 are equally spaced. In the use state, the protection pad body 1 bends towards the side away from the limiting block unit 3 to form an arc shape and is installed in the hook 5 of the spacer 4. As Figure 4 and Figure 5 shown, in the use state, the limiting block unit 3 cooperates with the grooves on both sides of the hook 5 of the spacer 4 to fix this utility model in the hook 5 of the spacer 4, and this utility model is supported by the hook 5. When this utility model is in use, the cable passes through the arc-shaped structure formed by the bending of the protection pad body 1. On the surface (i.e., the upper surface) of the protection pad body 1 away from the limiting block unit 3, two rows of heat dissipation and drainage grooves 6 are provided. Each row of heat dissipation and drainage grooves 6 includes more than one heat dissipation and drainage groove unit 7. In this utility model, each row of heat dissipation and drainage grooves 6 includes four heat dissipation and drainage groove units 7, and the four heat dissipation and drainage groove units 7 are equally spaced. The mutually remote ends of the two rows of heat dissipation and drainage groove units 7 penetrate through the side surface of the protection pad body 1 to discharge the rainwater between the cable and the protection pad body 1 and the heat dissipation of the cable in the use state.

[0022] As Figures 1 to 3 In this utility model, the number of heat dissipation and drainage groove units 7 is equal to the number of limiting block units 3, and there is a heat dissipation and drainage groove unit 7 corresponding to each limiting block unit 3 above. The width of the heat dissipation and drainage groove unit 7 is smaller than the width of the limiting block unit 3. In this utility model, the height of the limiting block unit 3 at one end of the edge of the protection pad body 1 is greater than that of the other end, and the depth of the heat dissipation and drainage groove 6 at one end of the edge of the protection pad body 1 is greater than that of the other end. The end with a larger depth of the heat dissipation and drainage groove unit 7 extends downward to the limiting block unit 3, and the inclination angle of the bottom of the heat dissipation and drainage groove unit 7 is equal to the inclination angle of the bottom surface of the limiting block unit 3.

[0023] As Figures 1 to 3 In this utility model, a heat dissipation and drainage hole 8 penetrating the upper and lower surfaces of the protection pad body 1 is provided between two adjacent limiting block units 3 on the protection pad body 1. The heat dissipation and drainage hole 8 is used to discharge the rainwater between the cable and the protection pad body 1 and the heat dissipation of the cable in the use state to further improve the heat dissipation and drainage effect of this utility model.

[0024] As Figures 1 to 3The limiting block unit 3 in the present utility model is made of the same material as the protection pad body 1 and is integrally formed. There is a gap between the opposite ends of the limiting block units 3 of the two rows of limiting blocks 2 in the present utility model, and the opposite ends of the heat dissipation and drainage groove units 7 of the two rows of heat dissipation and drainage grooves 6 are not connected to each other, so as to facilitate the rainwater to flow out towards both sides.
