Description

Technical Field

[0001] This utility model relates to the technical field of isolation and protection devices, and in particular to an isolation and protection device for power transmission towers. Background Technology

[0002] Currently, during the construction of power transmission towers, in order to prevent people from climbing them, a concrete protective base is usually poured at the bottom of the tower. This base not only has low isolation and protection performance, but also, if it is poured on the side of the road, it will generate a huge impact force on the vehicle if a traffic accident occurs, causing huge casualties.

[0003] Existing protective devices are often cumbersome to manufacture and cannot be quickly installed on the surface of transmission towers. Furthermore, due to the wide variety of transmission tower types on the market, they cannot be quickly installed, disassembled, or adapted to most types of transmission towers.

[0004] Therefore, we propose an isolation and protection device for power transmission towers. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an isolation and protection device for power transmission towers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An isolation and protection device for power transmission towers includes several protective shells. A water inlet is provided on the outer surface of the protective shell. Fixing grooves are provided on both sides of the surface of the protective shell. A sealing slider is engaged with the inner wall of the fixing groove. A rotating shaft is engaged with the inner side of the protective shell. An adjusting rod is movably provided on one side of the rotating shaft. A fixing ring is threadedly connected to one side of the adjusting rod.

[0008] As a further embodiment of this utility model: the protective shell is an irregular shell with a hollow inner wall. The protective shell is semi-circular when viewed from above. One of the water inlets is located at the top of one side of the protective shell surface, and the other water inlet is opened at the bottom of the protective shell surface. A water cap is threadedly connected to the surface of the water inlet.

[0009] As a further embodiment of this utility model: a sliding rod is fixedly provided at both ends on one side of the closed slider, a protective shell penetrates both sides of the fixed groove, a closed slider is engaged on both sides of the inner wall of the fixed groove, and the sliding rod penetrates the protective shell and engages with the inner wall of the fixed groove.

[0010] As a further embodiment of this utility model: the closed slider is semi-elliptical in plan view, and a threaded opening is provided on one side of the closed slider. The closed slider extends by sliding along the fixed groove, and the closed slider is threadedly connected to other closed sliders by means of the threaded opening.

[0011] As a further embodiment of this utility model: the adjusting rod includes a torsion shaft, the torsion shaft is perpendicular to and engaged with the rotation shaft, an extension rod is threadedly connected to one side of the torsion shaft, a main rod is fixedly provided on one side of the extension rod, and a connecting rod is fixedly provided on the other side of the main rod.

[0012] As a further improvement of this utility model: the fixing ring is an annular shell, and the surface of the fixing ring has a plurality of connection ports, which are threadedly connected to the connecting rod.

[0013] As a further improvement of this utility model, the inner diameter of the fixing ring is the same as the diameter of the power transmission pole to be fixed.

[0014] Compared with the prior art, this utility model provides an isolation and protection device for power transmission towers, which has the following beneficial effects:

[0015] 1. This utility model involves placing several protective shells around the outside of a power transmission tower, opening the water inlet at the top of the protective shell surface to inject water, thereby increasing the weight of the protective shell and its fixing force to the ground. After closing the water cover, pulling the sealing slider and using the threaded opening on its surface to fix several protective shells, the basic protection position is determined, which facilitates the quick installation of the whole device by the staff. In addition, the design of the upper and lower water inlets facilitates the transportation of the protective shells and reduces the transportation weight.

[0016] 2. This utility model involves fitting a fixing ring onto the transmission tower, determining the extension length using an adjusting rod, and connecting and fixing it to the protective shell. After filling the entire protective shell with water, the connection of the fixing ring to the transmission tower allows the weight of the protective shell to enhance the stability of the transmission tower, thereby improving the stability of the transmission tower in severe weather during the protection process.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] Example: An isolation and protection device for power transmission towers, such as... Figure 1 - Figure 4 As shown, the device includes several protective shells 1. A water inlet 2 is provided on the outer surface of each protective shell 1. Fixing grooves 3 are provided on both sides of the surface of each protective shell 1. A closed slider 4 is fitted into the inner wall of each fixing groove 3. A rotating shaft 5 is fitted into the inner side of each protective shell 1. An adjusting rod 6 is movably mounted on one side of the rotating shaft 5. A fixing ring 7 is threaded onto one side of the adjusting rod 6. The protective shell 1 is an irregular shell with a hollow inner wall. Viewed from above, the protective shell 1 has a semi-circular shape. One water inlet 2 is located at the top of one side of the protective shell 1, and the other water inlet 2 is located at the bottom of the protective shell 1. A water cap 8 is threaded onto the surface of each water inlet 2. Opening the water inlet 2 at the top of the protective shell 1 allows for water injection, increasing the weight of the protective shell 1 and its stability against the ground. The design of the upper and lower water inlets 2 facilitates the transportation of the protective shell 1 and reduces its weight during transport.

[0026] like Figure 1 - Figure 4As shown, a sliding rod 9 is fixedly installed at both ends on one side of the closed slider 4. The protective shell 1 passes through both sides of the fixed groove 3. The closed slider 4 is engaged with both sides of the inner wall of the fixed groove 3. The sliding rod 9 passes through the protective shell 1 and is engaged with the inner wall of the fixed groove 3. The closed slider 4 is semi-elliptical when viewed from above. A threaded opening 10 is opened on one side of the closed slider 4. The closed slider 4 slides along the fixed groove 3 to extend. The closed slider 4 is threadedly connected with other closed sliders 4 by means of the threaded opening 10, which increases its fixing force to the ground. When the water cover 8 is closed, the closed slider 4 is pulled and several protective shells 1 are fixed by means of the threaded opening 10 on its surface, thus determining the position of the basic protection.

[0027] like Figure 1 - Figure 3 As shown, the adjusting rod 6 includes a torsion shaft 11, which is perpendicular to and engaged with the rotation shaft 5. An extension rod 12 is threadedly connected to one side of the torsion shaft 11, and a main rod 13 is fixedly installed on one side of the extension rod 12. A connecting rod 14 is fixedly installed on the other side of the main rod 13. The fixing ring 7 is an annular shell, and several connection ports 15 are opened on the surface of the fixing ring 7. The connection ports 15 are threadedly connected to the connecting rod 14. The inner diameter of the fixing ring 7 is the same as the diameter of the power transmission pole body that needs to be fixed.

[0028] Working principle: The fixing ring 7 is fitted onto each support leg of the individual transmission tower or transmission iron tower, and is threadedly connected to the connecting rod 14 through the connecting port 15. The extension rod 12 is extended by turning the torsion shaft 11 to determine the foundation position of the protective shell 1. At this time, water is poured into the water inlet 2 of the protective shell 1 to increase the weight of the protection. The sealing slider 4 is pulled and connected by the threaded port 10 on its surface to fix several protective shells 1, thereby fixing the overall device.
