Description

Technical Field

[0001] This invention relates to the field of power construction, and more specifically to a pole-mounted insulating baffle device fixed on a utility pole. Background Technology

[0002] Pole-mounted switches are crucial equipment in overhead power distribution lines, playing a vital role in ensuring the safe and stable operation of the power grid. When installing a pole-mounted switch on a pole below a crossarm, if live conductors such as tension leads are located below the crossarm, an insulating baffle must be installed below the crossarm to ensure the safety of live-line work.

[0003] Currently, insulating barriers are generally hook-type insulating barriers, which are hung below the crossarm via hooks. Since the hook length on the insulating barrier is fixed (currently around 0.4m), and the positions of live conductors such as tension leads below the crossarm vary, it often happens that even after the insulating barrier is hung below the crossarm, some conductors (e.g., tension leads) or other live conductors remain below the barrier and are not effectively isolated. If the pole-mounted switch is to continue using live-line working methods, considering safety distances, the live-line working team needs to implement safety measures, such as insulating and wrapping the live parts near the pole-mounted switch installation point with insulating blankets or sleeves to isolate them before proceeding with the switch installation. This significantly increases construction time and affects the efficiency of pole-mounted switch installation.

[0004] On the other hand, after the hook-type insulating baffle is installed, the pole workers need to select a suitable position below the hook-type insulating baffle to install a lifting crossbeam, and then hang a pulley block on the lifting crossbeam for lifting the pole switch. Summary of the Invention

[0005] The purpose of this invention is to provide a pole-mounted insulating baffle device that can improve the installation efficiency of pole-mounted switches while ensuring that the insulating baffle effectively isolates live conductors such as tension leads located below the crossarm.

[0006] The technical solution of this invention is: A pole-mounted insulating baffle device fixed on a utility pole, comprising: Fixed support; A pole-mounted fixing device is installed on a fixed support and is used to fix the fixed support at any position on the pole. The pole-mounted fixing device includes a clamping strap, a hook on the fixed support, a mounting base on the fixed support, a rotating shaft on the mounting base, and a one-way motion mechanism for driving the rotating shaft to move in one direction. One end of the clamping strap is fixed to the rotating shaft, and the other end of the clamping strap is provided with a hook that cooperates with the hook. An insulating baffle is fixed to a fixed support.

[0007] In this scheme, the pole-mounted insulating baffle device can be fixed to any position on the pole using a pole-mounted fixing device, and the insulating baffle is fixed to the fixed support. In this way, the height of the insulating baffle can be adjusted according to actual needs, ensuring that live conductors such as tension leads located below the crossarm are effectively isolated above the insulating baffle. There is no need to install safety measures such as insulating blankets or insulating sleeves, which can effectively improve the installation efficiency of pole-mounted switches.

[0008] Preferably, the fixed support is equipped with a lifting ring. Since the fixed support is securely fixed to the pole by the clamping strap of the pole fixing device, its fixation is stable and reliable. Therefore, after installing the lifting ring on the fixed support, the pole-mounted switch can be directly lifted by passing a lifting rope through the lifting ring. There is no need to install an additional lifting crossarm, which not only saves the cost of the lifting crossarm but also the time required for its installation, further improving the installation efficiency of the pole-mounted switch.

[0009] Preferably, the one-way motion mechanism is a ratchet mechanism, which includes a ratchet fixed on a rotating shaft, a swing arm rotatably mounted on the rotating shaft, a drive pawl mounted on the swing arm and cooperating with the ratchet, and a check pawl mounted on a mounting base and cooperating with the ratchet. In this way, the clamping strap is securely fixed to the pole, preventing it from loosening.

[0010] Preferably, the one-way motion mechanism further includes a first return spring, the mounting base is provided with a first guide groove extending radially along the rotating shaft, the anti-return pawl is a anti-return plate, the anti-return plate slides along the first guide groove, and the anti-return plate abuts against the ratchet under the action of the first return spring.

[0011] Preferably, the unidirectional motion mechanism further includes a second return spring. The swing arm is provided with a second guide groove extending radially along the rotating shaft. The rotating shaft is provided with a fixing member with a slot. The driving pawl is a driving plate. The driving plate slides along the second guide groove and is engaged in the slot under the action of the second return spring.

[0012] Preferably, the fixed support includes a plug-in seat with a vertical insertion hole, and the insulating baffle has a plug-in post that mates with the vertical insertion hole. Thus, the insulating baffle is fixed to the fixed support by inserting the plug-in post into the vertical insertion hole, making the operation convenient and quick.

[0013] Preferably, it also includes a self-unlocking insertion hole locking mechanism. The fixed support also includes a connecting sleeve and a fixed seat fixed to one end of the connecting sleeve. The pole fixing device is set on the fixed seat, the insertion seat is fixed to the other end of the connecting sleeve, and the fixed seat is provided with a mating surface that mates with the pole. The self-unlocking insertion hole locking mechanism includes a third return spring, a fourth return spring, a receiving cavity disposed within the insertion seat, a guide cone located within the receiving cavity, a first guide hole and a second guide hole disposed within the insertion seat, a sliding push rod slidably disposed within the first guide hole, a push rod limiting block disposed on the sliding push rod, a baffle disposed on the fixed seat near one end of the connecting sleeve, and a locking rod slidably disposed within the second guide hole. The first guide hole is coaxial with the connecting sleeve and connects the inner hole of the connecting sleeve with the receiving cavity. The second guide hole is perpendicular to the first guide hole and connects the receiving cavity with the vertical insertion hole. The guide cone and the sliding push rod are coaxially distributed, and one end of the sliding push rod is connected to the other end via a connecting rod. One end of the locking rod abuts against the side of the guide cone under the action of the fourth return spring, and the sliding top rod moves towards the fixed seat side under the action of the third return spring until the top rod limiting block abuts against the baffle.

[0014] When the top rod limit block abuts against the baffle, the other end of the sliding top rod extends to the outside of the mating surface of the fixed seat, and the other end of the locking rod extends into the vertical insertion hole; when the pole fixing device fixes the fixed support at any position on the pole and the mating surface is in close contact with the pole, the other end of the sliding top rod abuts against the pole, and the other end of the locking rod is located outside the vertical insertion hole.

[0015] The fixed support is secured to the pole using a clamping strap, which is convenient and reliable to install. However, during actual construction, there is still a risk that the clamping strap may not be properly tightened when operating the one-way motion mechanism (the clamping strap may not be properly secured to the pole), leading to unstable installation of the insulating baffle and subsequent slippage of the fixed support when lifting the pole-mounted switch using the lifting ring, thus creating a safety hazard. To address this issue, this solution incorporates a self-unlocking insertion hole locking mechanism. Specifically, during the tightening of the clamping strap via the one-way motion mechanism, if the clamping strap is tightened and secures to the pole, the mating surface is pressed against the pole, the other end of the sliding top rod rests against the pole, and the other end of the locking rod is located outside the vertical insertion hole. This ensures that the insertion of the plug into the vertical insertion hole is not affected, thus not affecting the installation of the insulating baffle. If the clamping strap is not properly tightened during the tightening of the one-way motion mechanism, the locking mechanism will not be effective. If the strap is not locked and the clamping strap is not clamped to the pole, the other end of the sliding top rod will extend to the outside of the mating surface, and the other end of the locking rod will extend into the vertical insertion hole. Subsequently, when the operator installs the insulating baffle, the plug will be blocked by the locking rod in the vertical insertion hole and will not be able to be inserted smoothly into the vertical insertion hole. The insulating baffle cannot be installed smoothly, and subsequent operations cannot be performed. This serves as a reminder to the operator that they have not operated according to requirements, forcing the operator to lock the clamping strap through the one-way motion mechanism and clamp the clamping strap to the pole.

[0016] Preferably, the outer surface of the insertion base is provided with a threaded hole that communicates with the vertical insertion hole, and a set bolt is provided in the threaded hole. In this way, after the insertion post is inserted into the vertical insertion hole, the insertion post can be locked in the vertical insertion hole by the set bolt, thereby improving the installation stability of the insulating baffle.

[0017] Preferably, there are two insulating baffles at the same height, connected by a connector. The connector is attached to the insulating baffle via a clip or bolt. Connecting the two insulating baffles by the connector prevents the insulating baffles from rotating around the insertion post.

[0018] The beneficial effects of this invention are: Firstly, it can improve the installation efficiency of pole-mounted switches while ensuring that the insulating baffle effectively isolates live conductors such as tension leads located below the crossarm.

[0019] Secondly, it eliminates the need for a lifting crossarm, saving both the cost and time of installing it, thus further improving the installation efficiency of pole-mounted switches. Attached Figure Description

Detailed Implementation

[0026] Specific Implementation Example 1: As shown in the example Figure 1 , Figure 2 , Figure 3As shown, a pole-mounted insulating baffle device includes a fixed support 2, a pole-mounted fixing device 3, and an insulating baffle 1. The insulating baffle is fixed to the fixed support. The pole-mounted fixing device is disposed on the fixed support and is used to fix the fixed support at any position on the pole. The pole-mounted fixing device includes a clamping strap 3.3, a hook 3.5 disposed on the fixed support, a mounting base 3.1 disposed on the fixed support, a rotating shaft 3.2 rotatably disposed on the mounting base, and a one-way motion mechanism for driving the rotating shaft to move in one direction. One end of the clamping strap is fixed to the rotating shaft, and the other end of the clamping strap is provided with a hook 3.4 that cooperates with the hook. The hook is a hanging hole or hanging rod disposed on the fixed support. In this embodiment, the fixed support is provided with a threaded fixing bolt, which is parallel to the rotating shaft and constitutes the hook. The mounting base is fixedly connected to or hinged to the fixed support.

[0027] In this pole-mounted insulating baffle device, the fixed support can be fixed at any position on the pole using the pole-mounted fixing device. Specifically, the clamping strap is wrapped around the pole, and the hook is hung on the hanger. Then, the rotating shaft is driven by a one-way motion mechanism to move in one direction, winding the clamping strap around the rotating shaft, thereby clamping the clamping strap onto the pole. In this way, the height of the insulating baffle can be adjusted according to actual needs, ensuring that live conductors such as tension leads located below the crossarm are effectively isolated above the insulating baffle. There is no need to install safety measures such as insulating blankets or insulating sleeves, which can effectively improve the installation efficiency of pole-mounted switches.

[0028] Specifically, such as Figure 3 , Figure 4 As shown, the one-way motion mechanism is a ratchet mechanism, which includes a ratchet 3.7 fixed on a rotating shaft, a swing arm 3.6 rotatably mounted on the rotating shaft, a drive pawl 3.8 mounted on the swing arm and cooperating with the ratchet, and a check pawl 3.9 mounted on the mounting base and cooperating with the ratchet. In this way, the clamping strap is securely fixed to the pole, preventing it from loosening.

[0029] The one-way motion mechanism also includes a first return spring 3.10. A first guide groove 3.11 extending radially along the shaft is provided on the mounting base. A check pawl serves as a check plate, which slides along the first guide groove. One end of the first return spring rests against the mounting base, and the other end rests against the check plate. The check plate, under the action of the first return spring, rests against the ratchet.

[0030] The unidirectional motion mechanism also includes a second return spring. The swing arm has a second guide groove 3.12 extending radially along the rotating shaft. A fixing member is provided on the rotating shaft, and the fixing member has a retaining groove. The drive pawl is a drive plate, which slides along the second guide groove. Under the action of the second return spring, the drive plate engages with the retaining groove.

[0031] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the fixed support 2 includes an insertion seat 2.1, on which a vertical insertion hole 2.5 is provided, and an insulating baffle is provided with a plug-in post 1.1 that mates with the vertical insertion hole. Thus, the insulating baffle is fixed to the fixed support by inserting the plug-in post into the vertical insertion hole, making the operation convenient and quick. The insulating baffle is located above the insertion seat.

[0032] The outer surface of the insertion base is provided with a threaded hole that communicates with the vertical insertion hole, and a set bolt 2.6 is installed in the threaded hole. In this way, after the insertion post is inserted into the vertical insertion hole, the insertion post can be locked in the vertical insertion hole by the set bolt, thereby improving the installation stability of the insulating baffle.

[0033] The fixed support 2 also includes a connecting sleeve 2.2 and a fixed seat 2.3 fixed to one end of the connecting sleeve. The pole fixing device is set on the fixed seat. The insert seat is fixed to the other end of the connecting sleeve. The fixed seat is provided with a mating surface 2.7 that mates with the pole. In this embodiment, the mating surface is a cylindrical surface. When the clamping strap is clamped to the pole, the mating surface is in close contact with the outer surface of the pole, and the connecting sleeve extends radially along the pole.

[0034] Furthermore, such as Figure 1 , Figure 2 As shown, there are two insulating baffles 1. Each insulating baffle has a corresponding insertion post 1.1. There are two vertical insertion holes, each corresponding to a insertion post. The two insulating baffles are at the same height. The two insulating baffles are connected by a connector, which is secured to the insulating baffle with a clip or bolt. This connection prevents the insulating baffles from rotating around the insertion posts.

[0035] In this embodiment, each of the two insulating baffles is provided with a semi-circular baffle opening 1.2, which is located between the two insulating baffles. The baffle openings on the two insulating baffles constitute a pole through hole. When the fixed support is fixed on the pole and the insulating baffle is installed on the fixed support, the pole passes through the pole through hole.

[0036] Furthermore, such as Figure 1 , Figure 3 As shown, a lifting ring 2.4 is provided on the fixed support. In this embodiment, the lifting ring is set on the connecting sleeve. Since the fixed support is tightly fixed to the pole by the clamping strap of the pole fixing device, its fixation is stable and reliable; therefore, after setting the lifting ring on the fixed support, the pole-mounted switch can be directly lifted by passing the lifting rope through the lifting ring; there is no need to install an additional lifting crossarm, which not only saves the cost of the lifting crossarm but also the time required to install it, further improving the installation efficiency of the pole-mounted switch.

[0037] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that... like Figure 5 As shown, the pole-mounted insulating baffle device fixed on the pole also includes a self-unlocking insertion hole locking mechanism 4. The self-unlocking insertion hole locking mechanism includes a third return spring 4.0, a fourth return spring 4.9, a receiving cavity 4.1 disposed within the insertion seat, a guide cone 4.2 located within the receiving cavity, a first guide hole 4.3 and a second guide hole 4.4 disposed within the insertion seat, a sliding top rod 4.5 slidably disposed within the first guide hole, a top rod limiting block 4.6 disposed on the sliding top rod, a baffle 4.7 disposed on the fixed seat and near one end of the connecting sleeve, and a locking rod 4.8 slidably disposed within the second guide hole. In this embodiment, the fixed seat is provided with a mounting through hole 4.11, and the baffle is disposed on the inner wall of the mounting through hole. The mounting through hole communicates with the mating surface. The mounting through hole is coaxial with the first guide hole. The other end of the connecting sleeve is inserted into the mounting through hole so that the fixed seat is fixed to the other end of the connecting sleeve.

[0038] The guide cone and the sliding push rod are coaxially distributed, and one end of the sliding push rod is connected to the other end via a connecting rod. The outer diameter of the guide cone gradually increases from the fixed seat towards the insertion seat. In this embodiment, the other end of the sliding push rod is provided with a pressure plate 4.12.

[0039] The first guide hole is coaxial with the connecting sleeve and connects the inner hole of the connecting sleeve with the receiving cavity. The sliding push rod passes through the connecting sleeve and the mounting through hole. The push rod limiting block and the insert seat are located on the same side of the baffle. The third return spring is sleeved on the sliding push rod and is located inside the connecting sleeve. The third return spring is located between the push rod limiting block and the insert seat. Under the action of the third return spring, the sliding push rod moves towards the fixed seat side until the push rod limiting block abuts against the baffle.

[0040] The second guide hole is perpendicular to the first guide hole. The second guide hole corresponds one-to-one with the vertical insertion hole, and connects the receiving cavity to the corresponding vertical insertion hole. The locking rod corresponds one-to-one with the second guide hole. A locking rod stop 4.10 is provided on the locking rod. The fourth return spring corresponds one-to-one with the locking rod. The fourth return spring is sleeved on the locking rod, with one end abutting against the locking rod stop and the other end abutting against the insertion seat. One end of the locking rod abuts against the side of the guide cone under the action of the fourth return spring. In this embodiment, a hemispherical protrusion is provided on the end of the locking rod facing the guide cone.

[0041] like Figure 5 As shown, when the push rod limit block abuts against the baffle, the other end of the sliding push rod extends to the outside of the mating surface of the fixed seat (specifically, the pressure plate on the other end of the sliding push rod is located outside the mounting through hole), and the other end of the locking rod extends into the vertical insertion hole.

[0042] When the pole fixing device fixes the fixing support at any position on the pole and the mating surface is in close contact with the pole, the other end of the sliding top rod abuts against the pole, and the other end of the locking rod is located outside the vertical insertion hole.

[0043] The fixed support is secured to the pole using a clamping strap, which is convenient and reliable to install. However, during actual construction, there is still a risk that the clamping strap may not be properly tightened when operating the one-way motion mechanism (the clamping strap may not be properly secured to the pole), leading to unstable installation of the insulating baffle and subsequent slippage of the fixed support when lifting the pole-mounted switch using the lifting ring, thus creating a safety hazard. To address this issue, this solution incorporates a self-unlocking insertion hole locking mechanism. Specifically, during the tightening of the clamping strap via the one-way motion mechanism, if the clamping strap is tightened and secures to the pole, the mating surface is pressed against the pole, the other end of the sliding top rod rests against the pole, and the other end of the locking rod is located outside the vertical insertion hole. This ensures that the insertion of the plug into the vertical insertion hole is not affected, thus not affecting the installation of the insulating baffle. If the clamping strap is not properly tightened during the tightening of the one-way motion mechanism, the locking mechanism will not be effective. If the strap is not locked and the clamping strap is not clamped to the pole, the other end of the sliding top rod will extend to the outside of the mating surface, and the other end of the locking rod will extend into the vertical insertion hole. Subsequently, when the operator installs the insulating baffle, the plug will be blocked by the locking rod in the vertical insertion hole and will not be able to be inserted smoothly into the vertical insertion hole. The insulating baffle cannot be installed smoothly, and subsequent operations cannot be performed. This serves as a reminder to the operator that they have not operated according to requirements, forcing the operator to lock the clamping strap through the one-way motion mechanism and clamp the clamping strap to the pole.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
