Description

Technical Field

[0001] This invention relates to the field of bypass live-line working technology, and in particular to a gravity self-locking drain clamp. Background Technology

[0002] Drain clamps are an important tool in bypass live-line work, used for the electrical connection between bypass cables and overhead conductors, and have been widely used in recent years.

[0003] Traditional cable clamps are mainly divided into two types: general cable clamps and throat clamps. General cable clamps are often operated using insulated gloves, while throat clamps are often operated using insulated rods. The basic clamping principle of the two types of clamps is similar. Both have a groove at the top that is adapted to the cable to pre-suspend the clamp on the overhead cable. Then, by rotating the threaded structure, the clamping structure on it moves upward, thereby clamping and fixing the overhead cable.

[0004] In the process of realizing this invention, the inventors discovered that the prior art has at least the following technical problems:

[0005] Traditional cable clamps, which use a rotating threaded structure to move the clamping mechanism upwards to secure overhead cables, have the following drawbacks:

[0006] (1) When clamping, a large number of turns of the thread structure need to be rotated, which takes a long time and increases the workload of the operators.

[0007] (2) After repeated use, the threads are prone to loosening, and the clamping structure cannot effectively clamp and fix the overhead conductor, which may lead to unstable contact or even the risk of the conductor coming off, which is not conducive to safe operation. Summary of the Invention

[0008] The purpose of this invention is to provide a gravity self-locking drainage clamp to solve the above-mentioned technical problems of traditional drainage clamps.

[0009] The present invention provides a gravity self-locking drainage wire clamp, comprising a drainage wire clamp body (1), a compression spring (2), and a drainage wire clamp head assembly (3);

[0010] The drain clamp body (1) includes a first oblong hole (11), a second oblong hole (12), a first rectangular hole (13), a second rectangular hole (14), a mounting shaft (15), a connecting bolt hole (16), a fastening bolt hole (161), a first round hole (17), a contact (18), and a second round hole (19); wherein, the connecting bolt hole (16) and the fastening bolt hole (161) are used to install and fasten the bypass cable, and the contact (18) facilitates conductivity;

[0011] The drain line clamp assembly (3) includes two connecting plates (31), a first clamp (32), a clamp body (33), a second clamp (34), and a conductive shaft (35). The conductive shaft (35) and the clamp body (33) are separate structures. The lower end of the clamp body (33) has a V-groove structure, and the upper end has a threaded hole structure. The conductive shaft (35) passes through the second round hole (19) and the compression spring (2) and is connected to the clamp body (33) through a threaded structure. The first clamp (32) is installed at the second rectangular hole (14) by a pin connection, and the second clamp (34) is installed at the first rectangular hole (13) by a pin connection. The two connecting plates (31) are located on both sides of the drain line clamp body (1). One connecting plate is installed on the conductive shaft (35) and the first clamp (32) by a pin connection at both ends, and the other connecting plate is installed on the conductive shaft (35) and the second clamp (34) by a pin connection at both ends.

[0012] When the drain clamp assembly (3) is attached to the overhead conductor, the drain clamp body (1) moves downward under the influence of the gravity of the self-locking drain clamp and the gravity of the bypass cable, causing the first clamp (32) and the second clamp (34) to move inward into a closed state, and together with the clamp body (33), clamp and fix the overhead conductor.

[0013] Preferably, it also includes a current monitoring component (4);

[0014] The current monitoring component (4) includes a current transformer (41) and a data processing and transmission module (42). The current transformer (41) has a central hole that surrounds the mounting shaft (15). The current monitoring component (4) is bolted to the mounting shaft (15). When the clamp connects the overhead bare conductor and the lead wire, the current transformer (41) inputs the detected current data to the data processing and control module (42). After the current data is processed by the data processing and control module (42), a current signal is obtained. The data processing and control module (42) transmits the current signal to the handheld terminal through the wireless Bluetooth module.

[0015] Preferably, it also includes a fixing component (5);

[0016] The fixing component (5) includes a fixing rod (51), a fixing seat (52), and an operating handle (53); wherein, one end of the fixing seat (52) is in the first round hole (17), and the other end is in the first waist-shaped hole (11); one end of the fixing rod (51) is mounted on the second clamp (34) by a pin, and the other end passes through the waist-shaped hole and the first waist-shaped hole (11) on the fixing seat (52); one side of the operating handle (53) is provided with an operating hole (531); the thread on the side away from the operating hole (531) is engaged with the thread on the fixing seat (52), and is connected to the drain clamp body (1) by a pin; and the operating handle (53) and the drain clamp body (1) can rotate relative to each other.

[0017] The present invention has the following beneficial effects:

[0018] (1) The gravity self-locking drain clamp of the present invention can be directly self-locked by gravity after hanging bare wires, which is safe and fast, reduces the hanging operation time, and reduces the labor intensity of operators.

[0028] See Figure 1-6 The present invention provides a gravity self-locking drain clamp, comprising a drain clamp body 1, a compression spring 2, a drain clamp head assembly 3, a current monitoring assembly 4, and a fixing assembly 5.

[0029] like Figure 2 As shown, the drain clamp body 1 includes a first oblong hole 11, a second oblong hole 12, a first rectangular hole 13, a second rectangular hole 14, a mounting shaft 15, a connecting bolt hole 16, a fastening bolt hole 161, a first round hole 17, a contact 18, and a second round hole 19; wherein, the connecting bolt hole 16 and the fastening bolt hole 161 are used to install and fasten the bypass cable, and the contact 18 facilitates conductivity.

[0030] like Figure 3 As shown, the drain line clamp assembly 3 includes two connecting plates 31, a first clamp 32, a clamp body 33, a second clamp 34, and a conductive shaft 35. The conductive shaft 35 and the clamp body 33 are separate structures. The lower end of the clamp body 33 has a V-groove structure, and the upper end has a threaded hole structure. The conductive shaft 35 passes through the second circular hole 19 and the compression spring 2 and is connected to the clamp body 33 by a threaded structure. The first clamp 32 is installed at the second rectangular hole 14 by a pin, and the second clamp 34 is installed at the first rectangular hole 13 by a pin. The two connecting plates 31 are located on both sides of the drain line clamp body 1. One connecting plate is installed on the conductive shaft 35 and the first clamp 32 by pin connection at both ends, and the other connecting plate is installed on the conductive shaft 35 and the second clamp 34 by pin connection at both ends.

[0031] like Figure 4 As shown, when the drain clamp assembly 3 is in the relaxed state, the compression spring 2 is in the extended state, and the first jaw 32 and the second jaw 34 are also in the open state. When the drain clamp assembly 3 is attached to the overhead conductor, under the action of the gravity self-locking drain clamp itself and the gravity of the bypass cable, the drain clamp body 1 moves downward, driving the first jaw 32 and the second jaw 34 to move inward to the closed state, and together with the clamp body 33, clamps and fixes the overhead conductor. At this time, the compression spring 2 is in the compressed state, and the spring plays the role of ensuring that the clamp is in the open state when the clamp is in the relaxed state.

[0032] Specifically, the chuck body 33 and the conductive shaft 35 are fixed by a thread, and the conductive shaft 35 and the chuck body 33 are clearance-fitted, allowing the chuck body 33 to slide relative to the conductive shaft 35. The first jaw 32 forms a connecting rod structure with the chuck body 33 and the conductive shaft 35 via a connecting plate 31, and the second jaw 34 also forms a connecting rod structure with the chuck body 33 and the conductive shaft 35 via the connecting plate 31. A bypass cable is installed at the bolt hole 16 of the chuck body 33 and secured with screws at the fastening bolt hole 161. The operator separates the first clamp 32 and the second clamp 34, and attaches the drain clamp head assembly 3 to the overhead conductor. The V-shaped groove structure at the lower end of the clamp body 33 contacts the overhead conductor. The operator slowly releases the upward pushing force on the drain clamp. Under the action of only its own downward gravity and the gravity of the bypass cable, the clamp body 33 slides relative to the conductive shaft 35 and moves downward. At the same time, through the two linkage structures mentioned above, the first clamp 32 and the second clamp 34 move inward to a closed state, and together with the clamp body 33, they clamp and fix the overhead conductor.

[0033] like Figure 5 As shown, the current monitoring component 4 includes a current transformer 41 and a data processing and transmission module 42. The current transformer 41 has a central hole that surrounds the mounting shaft 15. The current monitoring component 4 is bolted to the mounting shaft 15. When the clamp connects the overhead bare conductor and the lead wire, the current transformer 41 inputs the detected current data to the data processing and control module 42. After the current data is processed by the data processing and control module 42, a current signal is obtained. The data processing and control module 42 transmits the current signal to a handheld terminal via a wireless Bluetooth module, realizing real-time monitoring of the current data through the lead wire, which is beneficial for safe operation.

[0034] like Figure 6 As shown, the fixing assembly 5 includes a fixing rod 51, a fixing seat 52, and an operating handle 53. One end of the fixing seat 52 is inside the first circular hole 17, and the other end is inside the first oblong hole 11. One end of the fixing rod 51 is mounted on the second clamp 34 via a pin, and the other end passes through the oblong hole and the first oblong hole 11 on the fixing seat 52. The operating handle 53 has an operating hole 531 on one side, and the thread on the side away from the operating hole 531 engages with the thread on the fixing seat 52. It is connected to the drain clamp body 1 via a pin, and the operating handle 53 and the drain clamp body 1 can rotate relative to each other. Specifically, after the drain clamp head assembly 3 is attached to and clamps the overhead conductor, the insulating operating rod is connected to the operating hole 531. Rotating the insulating operating rod two to three turns rotates the operating handle 53, causing the fixing seat 52 to move downwards and press the fixing rod 51, thus fixing the clamp and preventing the overhead conductor from falling off the clamp due to misoperation during operation.

[0035] The device in this embodiment has the following advantages:

[0036] (1) The gravity self-locking drain clamp provided in this embodiment of the invention can be directly self-locked by gravity after hanging bare wires, which is safe and fast, reduces the hanging operation time, and reduces the labor intensity of operators.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
