[0001] The utility model relates to the technical field of power distribution automation, in particular to an installation structure of a power distribution automation terminal and a utility pole. Background Art

[0002] The distribution switch monitoring terminal (FTU for short), also called the distribution automation terminal (FTU), distribution network automation feeder terminal, etc., is a general term for various remote monitoring and control units installed in the distribution network. Its main functions are: data acquisition and monitoring: real-time acquisition of electrical parameters, equipment status and other information of the distribution line; fault detection and diagnosis: timely detection of line faults, and accurate judgment and positioning; control function: can execute remote control instructions to realize the operation of switches and other equipment; communication function: data communication with the master station or other equipment, uploading collection information and receiving control instructions. The application of distribution automation terminals can improve the reliability, stability and intelligence level of the distribution system, realize efficient management and precise control of the distribution network, effectively reduce the time and scope of power outages, and improve the quality of power supply and service level.

[0003] The above-mentioned distribution automation terminal is generally installed on a utility pole or a utility pole. The specific installation method is to install a utility pole clamp or a circle of steel pipe belt on the utility pole. All electronic parts of the distribution switch monitoring terminal are installed in a steel cover, and the outside of the steel cover is provided with a mounting hole. The mounting hole and the utility pole clamp are connected by bolts, brackets, etc., so as to fix the steel cover to one side of the utility pole. Although the outer surface of the steel cover of the distribution switch monitoring terminal is coated with rain and sun protection paint, the anti-rust paint on the surface of the bolt is damaged after the bolt of the bracket is tightened by a wrench. After long-term rain and sun exposure, the bolt rusts and is extremely difficult to disassemble, which increases the difficulty of replacement and maintenance of the distribution switch monitoring terminal. Utility Model Content

[0004] Aiming at the defects in the prior art, the difficulty of disassembling and assembling the distribution switch monitoring terminal is reduced, and the efficiency of replacement and maintenance work is improved. The utility model provides a mounting structure of a distribution automation terminal and a pole, comprising a connecting plate, a clamp and a protective cover; a left clamping slot corresponding to an ear plate outside a steel cover of the distribution automation terminal is provided on the left side of the connecting plate, and two side walls of the left clamping slot are provided with first mounting holes corresponding to two through holes longitudinally distributed on the ear plate, and the ear plate is inserted into the left clamping slot, and each through hole and the corresponding first mounting hole are tightened by bolts, so that the left clamping slot clamps and fixes the ear plate; the clamping slot comprises a first steel belt and a second steel belt, and a right clamping slot adapted to the end of the first steel belt is provided on the right side of the connecting plate; the first steel belt is provided with two second mounting holes longitudinally distributed, and two side walls of the right clamping slot are provided with third mounting holes corresponding to the two second mounting holes, and the first steel belt is inserted into the right clamping slot, and each second mounting hole and the corresponding third mounting hole are tightened by bolts, so that the right clamping slot clamps and fixes the first steel belt; two protective covers are provided, and the two protective covers are respectively connected to the left and right sides of the connecting plate, so as to cover the bolts of the left clamping slot and the bolts of the right clamping slot.

[0005] The beneficial effect of the device is that the connecting plate is connected between the ear plate of the steel cover and the first steel band of the clamp by bolts, and after the bolts are tightened, two protective covers are covered from top to bottom on the left and right sides of the connecting plate to cover all the bolts. After the bolts are tightened with tools such as wrenches, the anti-rust paint on the outer surface of the bolts is damaged, but the protective cover completely covers the connected area, that is, the damaged area, thereby avoiding the problem of difficult maintenance and difficult disassembly caused by the corrosion of the bolts.

[0006] Preferably, the left card slot longitudinally penetrates the left side of the connecting plate, so that the opening direction of the left card slot is leftward. The right card slot longitudinally penetrates the right side of the connecting plate, so that the opening direction of the right card slot is rightward. The design of the left card slot and the right card slot is to avoid affecting the connection between the two sides of the connecting plate and the ear plate and the first steel belt.

[0007] Preferably, the outer sides of the two side walls of the left card slot are respectively provided with two longitudinally distributed left limit plates, and the distance between the two left limit plates on each side is the same as the width of the inner cavity of the protective cover; the two opposite side walls of the protective cover of the left card slot are provided with notches corresponding to the left part of the connecting plate and the ear plate, and the two left limit plates on each side are pressed against the inner side of the protective cover, so that the protective cover of the left card slot covers the left part of the limit plate and the ear plate. The protective cover slides from top to bottom into the two left limit plates on each side, and the friction generated by the two left limit plates pressing against the inner side of the protective cover clamps the protective cover, thereby preventing the protective cover from falling off.

[0008] Preferably, the outer sides of the two side walls of the right slot are respectively provided with two right limit plates distributed longitudinally, and the distance between the two right limit plates on each side is the same as the width of the inner cavity of the protective cover; the two opposite side walls of the protective cover of the right slot are provided with notches corresponding to the right part of the connecting plate and the end of the first steel belt, and the two right limit plates on each side are pressed against the inner side of the protective cover, so that the protective cover of the right slot covers the right part of the connecting plate and the end of the first steel belt. Similarly, the protective cover of the right slot is also clamped by friction.

[0009] Preferably, the outer side surfaces of all left limit plates and all right limit plates are provided with longitudinal slots, and the inner side surfaces of the protective covers are provided with longitudinal convex strips corresponding to the corresponding longitudinal slots, and the longitudinal convex strips are inserted into the longitudinal slots, so that the two protective covers are fastened to the left and right sides of the connecting plate respectively. The connection between the protective cover and the connecting plate is further strengthened by combining the longitudinal convex strips with the longitudinal slots, so that the protective cover will not loosen and fall off even in severe weather environments such as strong winds and heavy rains.

[0010] Preferably, the outer side surfaces of all the left limiting plates and the outer side surfaces of all the right limiting plates are provided with two parallel longitudinal slots.

[0011] Preferably, the middle part of the connecting plate is arched upwards. Since the connecting plate is subjected to downward stress for a long time, the middle part is a weak area, and the middle part is arched to strengthen the weak area, prevent fracture, and have higher strength.

[0012] Preferably, the thickness of the right portion of the connecting plate is greater than the thickness of the first steel strip, and the thickness of the left portion of the connecting plate is greater than the thickness of the ear plate. Since the thickness of the first steel strip is greater than the thickness of the ear plate, the thickness of the right portion of the connecting plate is greater than the thickness of the left portion. After the bolts are tightened, the left and right slots of the connecting plate are elastically deformed, and the ear edge and the first steel strip can be clamped.

[0013] Preferably, the material of the protective cover is anti-aging rubber, and the outer surface of the connecting plate is provided with an anti-rust layer. The protective cover itself is made of ASA engineering rubber plastic, which is a graft copolymer of acrylic rubber and acrylonitrile and styrene, and has strong anti-aging and anti-corrosion properties and a long service life.

DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0027] like Figure 1 As shown, this embodiment provides a mounting structure of a distribution automation terminal and a utility pole, comprising a connecting plate 1, a clamp 2 and a protective cover 3, wherein the clamp 2 is sleeved on the outside of the utility pole 21. The specific connection structure between the connecting plate 1 and the ear plate 5 of the steel cover 4 of the distribution automation terminal is as follows:

[0028] The left side of the connecting plate 1 is provided with a left slot 6 corresponding to the ear plate 5 outside the steel cover 4 of the power distribution automation terminal. The two side walls of the left slot 6 are provided with first mounting holes 8 corresponding to the two through holes 7 distributed longitudinally on the ear plate 5. The ear plate 5 is inserted into the left slot 6 and each through hole 7 and the corresponding first mounting hole 8 are tightened by bolts 9, so that the left slot 6 clamps and fixes the ear plate 5. Further, the left slot 6 runs through the left side of the connecting plate 1 longitudinally, so that the opening direction of the left slot 6 faces left. The outer side surfaces of the two side walls of the left slot 6 are respectively provided with two longitudinally distributed left limit plates 10, and the distance between the two left limit plates 10 on each side is the same as the width of the inner cavity of the protective cover 3; the two opposite side walls of the protective cover 3 of the left slot 6 are provided with notches 17 corresponding to the left part of the connecting plate 1 and the ear plate 5, and the two left limit plates 10 on each side are pressed against the inner side of the protective cover 3, so that the protective cover 3 of the left slot 6 covers the left part of the limit plate and the ear plate 5. The protective cover 3 slides downward into the two left limit plates 10 on each side, and the two left limit plates 10 are used to press against the inner side of the protective cover 3 to generate friction to clamp the protective cover 3, thereby preventing the protective cover 3 from falling off.

[0029] The specific connection structure between the connecting plate 1 and the clamp 2 is as follows:

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the clamp 2 includes a first steel band 11 and a second steel band 12, and a right clamping groove 13 adapted to the end of the first steel band 11 is provided on the right side of the connecting plate 1; the first steel band 11 is provided with two second mounting holes 14 distributed longitudinally, and the two side walls of the right clamping groove 13 are provided with third mounting holes 15 corresponding to the two second mounting holes 14 one by one, and the first steel band 11 is inserted into the right clamping groove 13 and each second mounting hole 14 and the corresponding third mounting hole 15 are tightened by bolts 9, so that the right clamping groove 13 clamps and fixes the first steel band 11. In order to facilitate connection, the end of the first steel band 11 is longer than the end of the second steel band 12. Furthermore, the right clamping groove 13 longitudinally runs through the right side of the connecting plate 1, so that the opening direction of the right clamping groove 13 faces rightward. The design of the left clamping groove 6 and the right clamping groove 13 is to not affect the connection between the two sides of the connecting plate 1 and the ear plate 5 and the first steel band 11. Two longitudinally distributed right limit plates 16 are respectively provided on the outer side surfaces of the two side walls of the right slot 13, and the distance between the two right limit plates 16 on each side is the same as the width of the inner cavity of the protective cover 3; the two opposite side walls of the protective cover 3 of the right slot 13 are provided with notches 17 corresponding to the right part of the connecting plate 1 and the end of the first steel belt 11, and the two right limit plates 16 on each side are pressed against the inner side surface of the protective cover 3, so that the protective cover 3 of the right slot 13 covers the right part of the connecting plate 1 and the end of the first steel belt 11. Similarly, the protective cover 3 of the right slot 13 is also clamped by friction.

[0031] like Figure 1 , Figure 6 , Figure 8 and Fig. 9 As shown, in this embodiment, there are two protective covers 3, which are respectively connected to the left and right sides of the connecting plate 1, thereby covering the bolts 9 of the left slot 6 and the bolts 9 of the right slot 13. The outer side surfaces of all left limit plates 10 and the outer side surfaces of all right limit plates 16 are provided with two parallel longitudinal slots 18, and the inner side surfaces of the protective covers 3 are provided with longitudinal convex strips 19 corresponding to the corresponding longitudinal slots 18. The longitudinal convex strips 19 are inserted into the longitudinal slots 18, thereby fastening the two protective covers 3 to the left and right sides of the connecting plate 1, respectively. By combining the longitudinal convex strips 19 with the longitudinal slots 18, the connection between the protective cover and the connecting plate 1 is further strengthened, and the protective cover will not loosen and fall off even in severe weather environments such as strong winds and heavy rain.

[0032] like Figure 5As shown, in this embodiment, the connecting plate 1 is connected between the ear plate 5 of the steel cover 4 and the first steel strip 11 of the clamp 2 by bolts 9. After the bolts 9 are tightened, the two protective covers 3 are covered from top to bottom on the left and right sides of the connecting plate 1 to cover all the bolts 9. After the bolts 9 are tightened in conjunction with tools such as a wrench, the anti-rust paint on the outer surface of the bolts 9 is damaged, but the protective cover 3 completely covers the connected part, that is, the damaged part, thereby avoiding the problem of difficult maintenance and difficult disassembly caused by the corrosion of the bolts 9. Since the thickness of the right part of the connecting plate 1 is greater than the thickness of the first steel strip 11, and the thickness of the left part of the connecting plate 1 is greater than the thickness of the ear plate 5. Since the thickness of the first steel strip 11 is greater than the thickness of the ear plate 5, the thickness of the right part of the connecting plate 1 is greater than the thickness of the left part. After the bolts 9 are tightened, the left and right card slots 6 and 13 of the connecting plate 1 undergo elastic deformation, and the ear edge and the first steel strip 11 can be clamped.

[0033] In this embodiment, the material of the protective cover 3 is anti-aging rubber, and the outer surface of the connecting plate 1 is provided with an anti-rust layer. The protective cover 3 itself is made of ASA engineering rubber plastic, which is a graft copolymer of acrylic rubber body and acrylonitrile and styrene, and has strong anti-aging and corrosion resistance and long service life. Even if the anti-rust layer at the connection is destroyed after the connecting plate 1 and the bolt 9 are tightened, the protective cover 3 completely covers the connection of the connecting plate 1, so there is no rust problem at the connection of the connecting plate 1, and the anti-rust layer of the rest of the connecting plate 1 is intact and there is no rust problem. In addition, the middle part of the connecting plate 1 is arched upward by 20. Because the connecting plate 1 is subjected to downward stress for a long time, the middle part is a weak area. The middle part is strengthened by the arch 20 to prevent breakage and have higher strength.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
