Description

Technical Field

[0001] This invention relates to the field of power distribution network technology, and in particular to a special clamp for service drop lines and a method for connecting service drop lines. Background Technology

[0002] Currently, in the wiring work of service drop lines in power systems, traditional methods such as parallel trench clamps or manual winding are commonly used for splicing. This presents the following main problems: Existing wiring methods result in messy, "spider web"-like wiring, which not only affects aesthetics but also causes significant inconvenience for installation, inspection, and maintenance. Workers often need to climb up and down poles multiple times during wiring operations, posing a risk of electric shock, and the possibility of human bodies entering the circuit can easily lead to safety accidents. Traditional methods are cumbersome, time-consuming, require large shifts of personnel, and have low overall work efficiency. Summary of the Invention

[0003] To address the problems of cumbersome operation, long time consumption, large number of staff required, and low overall work efficiency in existing technologies, this invention provides a special clamp for service drop lines and a method for connecting service drop lines.

[0004] This application provides a special clamp for a customer service line, used to overlap a lead wire and a main line, including a first guide plate, a second guide plate, an adjusting plate, a pre-tightening member, and a locking member. The first guide plate has a first groove; the second guide plate is arranged opposite to the first guide plate along a first direction to clamp the lead wire and the main line, and the second guide plate has a second groove; the adjusting plate is disposed between the first and second guide plates, and the first groove and the second groove are respectively arranged opposite to the front and back of the adjusting plate along the first direction; the pre-tightening member is detachably and movably disposed between the first guide plate, the second guide plate, and the adjusting plate, and the pre-tightening member has a first operating end for connecting an insulating operating rod. The pre-tightening member includes a first state, a second state, and a third state that can be switched via the first operating end. When the pre-tightening member is in the first state, the first guide wire... The first guide plate, the second guide plate, and the adjusting plate are separated. When the pre-tightening member is in the second state, the first guide plate and the adjusting plate are clamped together. When the pre-tightening member is in the third state, the first guide plate and the second guide plate clamp the adjusting plate. The locking member is at least movably connected to the first guide plate and the second guide plate. The locking member has a second operating end for connecting an insulating operating rod. The locking member includes a relaxed state and a locked state that are switched via the second operating end. When the locking member is in the relaxed state, the first guide plate and the second guide plate are separated. When the locking member is in the locked state, the first guide plate and the second guide plate clamp the adjusting plate.

[0005] In some embodiments, the preload includes a preload bolt and a movable nut threaded onto the preload bolt. The first guide plate has a first connecting hole, the second guide plate has a second connecting hole, and the adjusting plate has a third connecting hole. The first connecting hole has a thread that matches the preload bolt. The diameters of the first and third connecting holes are smaller than the maximum diameter of the movable nut, and the diameter of the second connecting hole is larger than the maximum diameter of the movable nut. The preload bolt passes through the second and third connecting holes in sequence and is threadedly connected to the first guide plate through the first connecting hole. When the pre-tightening member moves from the first state to the second state, the pre-tightening bolt is threadedly connected to the first guide plate, and the movable nut abuts against the adjusting plate to press against the first guide plate. When the pre-tightening member moves from the second state to the third state, the pre-tightening bolt continues to rotate so that the first guide plate and the second guide plate clamp the adjusting plate.

[0006] In some embodiments, the adjusting plate includes a first clamping portion disposed opposite to the first wire groove, a second clamping portion disposed opposite to the second wire groove, and an intermediate portion for connecting the first clamping portion and the second clamping portion into one piece; The first clamping portion is recessed in a direction away from the first groove to form a first groove, and the second clamping portion is recessed in a direction away from the second groove to form a second groove.

[0007] In some embodiments, the first guide plate has two first grooves, and the second guide plate has two second grooves, with the first grooves and the second grooves arranged opposite to each other along the first direction; The first clamping part protrudes from the side opposite to the first groove to form a first protrusion, and the second clamping part protrudes from the side opposite to the second groove to form a second protrusion.

[0008] In some embodiments, the adjusting plate has multiple specifications, and the first groove and the second groove of the adjusting plate of different specifications have different recess depths.

[0009] In some embodiments, the locking element includes a locking bolt, the first guide plate has a first locking hole with a thread matching the locking bolt, the second guide plate has a second locking hole, the adjusting plate has a third locking hole, the locking bolt passes through the second locking hole and the third locking hole, and is threadedly connected to the first guide plate through the first locking hole, so that the first guide plate and the second guide plate clamp the adjusting plate.

[0010] In some embodiments, the preload bolt includes a preload head and a preload rod connected to the preload head, and the locking bolt includes a locking head and a locking rod connected to the locking head; Along the axial direction of the pre-tightening bolt, the length of the pre-tightening bolt head is L1, and along the axial direction of the locking bolt, the length of the locking bolt head is L2, where L1 ≥ L2.

[0011] In some embodiments, the locking element further includes a spring washer disposed between the locking bolt head and the second guide plate.

[0012] In some embodiments, the preload element further includes an operating ring connected to the preload bolt head to form the first operating end.

[0013] This application provides a method for splicing a service drop line, comprising the aforementioned service drop line clamp and insulated operating rod. The service drop line splicing method includes: S1. Move the pre-tightening member to the first state and move the locking member to the relaxed state; S2. Insert at least a portion of the end of the drain wire into the first groove, and then move the pre-tightening member to the second state so that the adjusting plate comes into close contact with the first guide plate, thereby clamping at least a portion of the end of the drain wire in the first groove. S3. Connect the first operating end to the insulating operating rod, and then use the insulating operating rod to lift the special clamp for the service line to the main line, so that the main line is inserted between the second wire groove and the adjusting plate. S4. The pre-tightening member is moved from the second state to the third state by the insulating operating rod, so that the second guide plate and the first guide plate clamp the adjusting plate, thereby clamping at least a portion of the main flow line in the second line groove. S5. Retract the insulating operating rod and replace it with an operating structure that matches the second operating end. If the structure of the second operating end is the same as that of the first operating end, skip this step. S6. The locking member is moved from the relaxed state to the locked state by the insulating operating rod, so that the second guide plate and the first guide plate clamp the adjusting plate, thereby realizing the overlap of the diversion line and the main line. S7. Remove the pre-tightening component using the insulating operating rod.

[0014] Compared with the prior art, the special clamp for the service drop line provided by this invention has the following advantages: when the special clamp for the service drop line is used to connect the lead wire and the main line, there is no need for workers to climb to heights. The operation process only uses an insulated operating rod, which is simple and can be operated by a single person. This improves the safety of workers and also increases their work efficiency.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figure 8 , Figure 9 , Figure 10 The diagram shows a dedicated clamp for the service drop line, used to connect the current guide wire M to the main current line N. It should be noted that the current guide wire M is used to direct the current on the main current line N to the circuit containing the current guide wire M. In practical applications, the service drop line is the aforementioned current guide wire M, used to direct the current on the main current line N to the user.

[0024] like Figure 1 , Figure 2 As shown, the dedicated clamp for the customer service line includes a first guide plate 100, a second guide plate 200, an adjusting plate 400, a pre-tightening member 300, and a locking member 500. The first guide plate 100 is provided with a first groove 101. The second guide plate 200 is positioned opposite the first guide plate 100 along a first direction X to clamp the lead wire M and the main flow line N, and the second guide plate 200 has a second groove 201. When the dedicated clamp for the customer service line simultaneously clamps the lead wire M and the main flow line N, the current on the main flow line N can be guided to the lead wire M through the dedicated clamp. It should be noted that, as... Figure 8 , Figure 9 , Figure 10 As shown, the dedicated clamp for the service drop line is used to clamp the end of the lead wire M, and the end of the lead wire M is exposed. The main current line N is also exposed. When the lead wire M is connected to the main current line N through the dedicated clamp, the current can be conducted to the lead wire M through the dedicated clamp. Based on the above description, it can be understood that the first guide plate 100 and the second guide plate 200 are both made of conductive materials, such as aluminum alloy.

[0025] like Figure 1 , Figure 2 and Figure 4 , Figure 5 , Figure 6As shown, the aforementioned adjusting plate 400 is disposed between the first guide plate 100 and the second guide plate 200. The first groove 101 and the second groove 201 are respectively disposed opposite to the front and back of the adjusting plate 400 along the first direction X. The pre-tightening member 300 is detachably and movably disposed between the first guide plate 100, the second guide plate 200 and the adjusting plate 400. The pre-tightening member 300 has a first operating end 301 for connecting the insulating operating rod S. The pre-tightening member 300 includes a first state, a second state and a third state that can be switched through the first operating end 301 (i.e., the operator can directly or using the insulating operating rod S to operate the first operating end 301 to switch the pre-tightening member 300 between the first state, the second state and the third state). When the pre-tightening member 300 is in the first state, the first guide plate 100, the second guide plate 200 and the adjusting plate 400 are separated. When the pre-tightening member 300 is in the second state (i.e., ... Figure 4 (as shown in the diagram), the first guide plate 100 and the adjusting plate 400 are clamped together. When the pre-tightening member 300 is in the third state (i.e., Figure 5 (As shown in the diagram), the first guide plate 100 and the second guide plate 200 clamp the adjusting plate 400.

[0026] With the above design, the operator can first adjust the pre-tightening component 300 to the first state on the ground, then insert the end of the drain wire M into the first wire groove 101, and then manually adjust the pre-tightening component 300 to the second state, so that the end of the drain wire M is clamped in the first wire groove 101 between the adjusting plate 400 and the first guide plate 100 (there is no current before the drain wire M is connected, so the operator can safely operate it by hand). Figure 4 Then connect the insulating operating rod S to the first operating end 301 of the pre-tightening member 300, and lift the special clamp for the downstream customer service line through the insulating operating rod S and send it to the overlap of the main flow line N, so that the main flow line N is inserted between the adjusting plate 400 and the second guide plate 200 (or the second wire groove 201) (see reference). Figure 9 Then, by operating the insulating operating rod S, the pre-tightening member 300 is moved to the third state. At this time, the main flow line N can be clamped in the second groove 201 between the adjusting plate 400 and the second guide plate 200 (e.g., Figure 10 This allows for the initial connection and fixation of the drain line M and the main line N using the dedicated clamp for the service line (since further tightening is required later using locking component 500, the pre-tightening component 300 only provides initial fixation). The above operation can be performed without requiring workers to climb, and can be done using only an insulated operating rod S, so it can be completed by a single person.

[0027] Please see Figure 1 , Figure 2 and Figure 4 , Figure 5 , Figure 6As shown, the locking member 500 is movably connected to at least the first guide plate 100 and the second guide plate 200. The locking member 500 has a second operating end 501 for connecting the insulating operating rod S. The locking member 500 includes a relaxed state and a locked state that can be switched via the second operating end 501 (i.e., the operator can directly or using the insulating operating rod S to operate the second operating end 501 to switch the locking member 500 between the relaxed and locked states). When the locking member 500 is in the relaxed state, the first guide plate 100 and the second guide plate 200 are separated (e.g., ...). Figure 4 When the locking element 500 is in the locked state, the first guide plate 100 and the second guide plate 200 clamp the adjusting plate 400 (e.g., Figure 5 With the above design, after the dedicated service line is fixed to the main line N by the pre-tightening member 300, the operator can operate the second operating end 501 again through the insulated operating rod S to move the locking member 500 from the loose state to the locked state, thereby achieving the final connection between the drain line M and the main line N. It should be noted that before the operator lifts the dedicated service line and sends it to the connection point of the main line N using the pre-tightening member 300, the locking member 500 needs to be moved to the loose state. This process can be performed directly on the ground. After the operator moves the pre-tightening member 300 to the third state using the insulating operating rod S, when operating the locking member 500, if the structure of the first operating end 301 of the pre-tightening member 300 differs from the structure of the second operating end 501 of the locking member 500, the insulating operating rod S needs to be retrieved and its end structure replaced. If the structure of the first operating end 301 of the pre-tightening member 300 is the same as the structure of the second operating end 501 of the locking member 500, the operation can be directly switched to the locking member 500. It can be understood that the above process only requires one insulating operating rod S and can be completed independently by a single person.

[0028] In summary, when the dedicated service line provided in this application connects the diversion line M and the main line N, no workers are required to climb to heights. The operation is carried out using only one insulated operating rod S, which is simple and can be operated by a single person. This improves the safety of workers and also increases their work efficiency.

[0029] The technical details of each component will be introduced below.

[0030] In some implementations, such as Figure 1 , Figure 2As shown, the preload 300 includes a preload bolt 31 and a movable nut 32 threaded onto the preload bolt 31. The first guide plate 100 has a first connecting hole 102, the second guide plate 200 has a second connecting hole 202, and the adjusting plate 400 has a third connecting hole. The first connecting hole 102 has a thread matching the preload bolt 31. The diameters of the first and third connecting holes are smaller than the maximum diameter of the movable nut 32, while the diameter of the second connecting hole 202 is larger than the maximum diameter of the movable nut 32. The preload bolt 31 passes through the second and third connecting holes sequentially and is threadedly connected to the first guide plate 100 through the first connecting hole 102. With this design, as the preload bolt 31 gradually screws into the first connecting hole 102, the movable nut 32 cannot pass through the third connecting hole, thus allowing the adjusting plate 400 to be pressed against the first guide plate 100. It should be noted that the thread direction of the movable nut 32 is the same as the thread direction of the first connecting hole 102. Therefore, after the movable nut 32 is pressed against the adjusting plate 400 (see...), Figure 4 As the pre-tightening bolt 31 continues to screw into the first connecting hole 102, the movable nut 32 will also rotate relative to the pre-tightening bolt 31, without jamming the pre-tightening bolt 31. When the locking member 500 is in the locked state, the pre-tightening member 300 needs to be removed. Since the diameter of the second connecting hole 202 is larger than the maximum outer diameter of the movable nut 32, the movable nut 32 can pass through the second connecting hole 202 along with the pre-tightening bolt 31, thereby achieving complete removal of the pre-tightening member 300.

[0031] When the pre-tensioning member 300 moves from the first state to the second state, the pre-tensioning bolt 31 is threadedly connected to the first guide plate 100, and the movable nut 32 abuts against the adjusting plate 400 to press it against the first guide plate 100. When the pre-tensioning member 300 moves from the second state to the third state, the pre-tensioning bolt 31 continues to rotate so that the first guide plate 100 and the second guide plate 200 clamp the adjusting plate 400. The above design has a simple structure, the components are easy to manufacture and process, and it is very easy to operate.

[0032] In some implementations, such as Figure 1 , Figure 2 As shown, the adjusting plate 400 includes a first clamping portion 41 disposed opposite to the first groove 101, a second clamping portion 42 disposed opposite to the second groove 201, and an intermediate portion 43 for connecting the first clamping portion 41 and the second clamping portion 42 into one piece. In practical applications, the non-integral structure of the adjusting plate 400 facilitates production and operation.

[0033] Please see Figure 7The first clamping portion 41 is recessed in a direction away from the first wire groove 101 to form a first groove 411, and the second clamping portion 42 is recessed in a direction away from the second wire groove 201 to form a second groove 421. The first groove 411 and the second groove 421 can cooperate with the first wire groove 101 and the second wire groove 201 to clamp the drain line M and the main flow line N.

[0034] In some implementations, such as Figure 1 , Figure 2 , Figure 7 As shown, the first guide plate 100 has two first grooves 101, and the second guide plate 200 has two second grooves 201. The first grooves 101 and the second grooves 201 are arranged opposite each other along the first direction X. The first clamping part 41 protrudes from the side opposite to the first groove 411 to form a first protrusion 412, and the second clamping part 42 protrudes from the side opposite to the second groove 421 to form a second protrusion 422. In actual production and processing, the above-mentioned adjusting plate 400 can usually be formed by integral stamping. The above structural design can facilitate stamping and reduce the production difficulty of the adjusting plate 400. At the same time, the first protrusion 412 of the first clamping part 41 and the second protrusion 422 of the second clamping part 42 can be embedded in the second groove 201 and the first groove 101 respectively to form a fitting structure. This fitting structure can restrict the position of the first guide plate 100, the adjusting plate 400 and the second guide plate 200 after clamping, and avoid deflection or misalignment.

[0035] In some embodiments, the adjusting plate 400 has various specifications, with different recess depths in the first groove 411 and the second groove 421 of the adjusting plate 400. This design allows the service drop clamp to be adapted to service drop cables of various diameters, enhancing its adaptability in practical applications. The adjusting plate 400 can be made of aluminum alloy, which is conductive while also possessing a certain degree of elasticity and deformation capability to accommodate the structure of the main line N and the drain line M, thus improving the stability of the main line N and the drain line M after clamping.

[0036] In some implementations, such as Figure 1 , Figure 2 As shown, the locking component 500 includes a locking bolt 51. The first guide plate 100 has a first locking hole 103 with a thread that matches the locking bolt 51. The second guide plate 200 has a second locking hole 203, and the adjusting plate 400 has a third locking hole. The locking bolt 51 passes through the second and third locking holes and is threadedly connected to the first guide plate 100 through the first locking hole 103, so that the first and second guide plates 100 clamp the adjusting plate 400. The above design is simple, the components are easy to manufacture, and the operation is very simple.

[0037] In some embodiments, as shown in the figure, the preload bolt 31 includes a preload head 311 and a preload rod 312 connected to the preload head 311, and the locking bolt 51 includes a locking head and a locking rod connected to the locking head. The length of the preload head 311 along the axial direction of the preload rod 312 is L1, and the length of the locking head along the axial direction of the locking rod is L2, where L1 ≥ L2. In practical applications, the difference between L1 and L2 is greater than 2 cm and less than 5 cm. With this design, when the pre-tightening bolt 31 and the locking bolt 51 simultaneously clamp the first guide plate 100 and the second guide plate 200 to the adjusting plate 400 (i.e., when the locking member 500 is in the locked state and the pre-tightening member 300 is in the third state), the pre-tightening bolt head 311 can protrude from the locking bolt head, making it easy for workers to operate the pre-tightening bolt 31 by hand or with tools; for example, it is convenient for workers to remove the pre-tightening bolt 31 and the movable nut 32 after tightening the locking bolt 51, so as to realize the recycling and reuse of the pre-tightening member 300.

[0038] In some implementations, such as Figure 1 , Figure 2 As shown, the locking component 500 also includes a spring washer 52, which is disposed between the locking bolt head and the second guide plate 200. During the process of the locking bolt 51 gradually tightening the first guide plate 100 and the second guide plate 200, the aforementioned spring washer 52 can generate a gradually increasing clamping force on the locking bolt head and the second guide plate 200, reducing the probability of the locking bolt 51 loosening. It also allows the first guide plate 100 and the second guide plate 200 to also receive a gradually increasing clamping force. The operator can then adjust the clamping force on the drainage line M and the main flow line N according to actual needs, thereby avoiding damage to the drainage line M and the main flow line N. (The structure of the aforementioned spring washer 52 is common knowledge in the art and will not be described in detail here.) In some implementations, such as Figure 1 , Figure 2 As shown, the pre-tightening member 300 also includes an operating ring 33, which is connected to the pre-tightening bolt head 311 to form a first operating end 301. The structure of the operating end of the insulating operating rod S can be adaptively adjusted according to the structure of the first operating end 301. In this embodiment, the insulating operating rod S can be a clamping mechanism for clamping the operating ring 33 and the pre-tightening bolt head 311 (the structure of the insulating operating rod S is prior art and common knowledge to those skilled in the art, and will not be further described here). The operating ring 33 has a ring in the middle. When the pre-tightening member 300 is removed, the ring of the operating ring 33 can be easily hooked or sleeved with the insulating operating rod S, so that the pre-tightening member 300 will not fall off after being completely detached, and can always maintain a connection with the insulating operating rod S, ensuring the stable recovery of the pre-tightening member 300.

[0039] This application provides a method for splicing a service drop line, using the aforementioned service drop line-specific clamp and insulated operating rod S. It should be noted that the aforementioned insulated operating rod S is a very common operating tool used by those skilled in the art and is considered common knowledge; therefore, it will not be described in detail here. The service drop line splicing method includes: S1. Move the pre-tightening member 300 to the first state and move the locking member 500 to the relaxed state. The above operation is to facilitate the direct insertion of the drain line M into the first groove 101 between the adjusting plate 400 and the first guide plate 100 from the side of the drain line M end.

[0040] S2. Insert at least a portion of the end of the drainage line M into the first groove 101, and then move the pre-tightening member 300 to the second state so that the adjusting plate 400 comes into contact with the first guide plate 100, thereby clamping at least a portion of the end of the drainage line M into the first groove 101. The above-mentioned fixing process of the drainage line M can be completed directly at a low position, which is safer, and the fixing operation can be completed by hand or with tools, which is relatively simple.

[0041] S3. Connect the first operating end 301 to the insulating operating rod S, and then use the insulating operating rod S to lift the special clamp for the downstream service line to the main service line N, so that the main service line N is inserted between the second wire groove 201 and the adjusting plate 400. Only one insulating operating rod S is needed, and it can be operated by a single person.

[0042] S4. By moving the pre-tightening member 300 from the second state to the third state using the insulating operating rod S, the second guide plate 200 and the first guide plate 100 clamp the adjusting plate 400, thereby clamping at least a portion of the main flow line N in the second line groove 201. Only one insulating operating rod S is needed, and a single person can achieve the initial overlap of the flow line M.

[0043] S5. Retract the insulating operating rod S and replace it with an operating structure that matches the second operating end 501. If the second operating end 501 has the same structure as the first operating end 301, skip this step. In some embodiments, based on the above description, the structures of the first operating end 301 and the second operating end 501 are different. The locking member 500 is a locking bolt 51. After the pre-tightening member 300 is moved to the third state, it is necessary to retract the insulating operating rod S and replace the operating end of the insulating operating rod S with a sleeve for tightening the locking bolt 51, thereby fixing the locking member 500.

[0044] S6. By using the insulating operating rod S, the locking member 500 is moved from the relaxed state to the locked state, so that the second guide plate 200 and the first guide plate 100 clamp the adjusting plate 400, thereby realizing the overlap of the diversion line M and the main flow line N. This can also be accomplished with only one insulating operating rod S, which is convenient for single-person operation.

[0045] S7. Remove the pre-tightening component 300 using the insulated operating rod S. This removal process also requires only one insulated operating rod S and can be completed by a single person.

[0046] It should be noted that in the traditional process of splicing the drain line M, at least two insulated operating rods S are required because the clamping process of both the drain line M and the main line N needs to be considered. One insulated operating rod S is used to maintain the stability of the entire device, and the other insulated operating rod S is used to tighten and lock for clamping and fixing. Therefore, the service line splicing method provided in this application only requires one insulated operating rod S to complete the splicing operation of the drain line M and the main line N, which is convenient for single-person operation, simple to operate, and improves the work efficiency of the staff.
