Description

Technical Field

[0001] This utility model relates to the technical field of linear towers, specifically a linear tower resistant to cold regions. Background Technology

[0002] Straight-line towers, also known as cross-line towers, are the most commonly used tower type for power transmission lines. In power transmission lines, straight-line towers are generally used to bear the weight of the conductors, i.e., the vertical load. Common straight-line tower types include the T-shaped, cup-shaped, and cat-head-shaped types.

[0003] For example, a dual-circuit linear tower with authorization announcement number "CN219974045U" solves the problem that existing dual-circuit linear towers cannot provide stable installation support and cannot guarantee the safety of dual-circuit linear towers. The above method involves placing the tower feet and connecting blocks at the corresponding positions at the bottom of the inner cavity of the mounting base. The toothed block clamping plate can then move along the inner cavity of the guide block under the action of the rotating structure, so that the outer end of the toothed block clamping plate enters the interior of the square clamping hole on the corresponding connecting block. In this way, the connecting block is fixed in the inner cavity of the mounting base by the toothed block clamping plate, ensuring the stability of the tower feet and connecting blocks. Considering the complexity of the installation environment of existing dual-circuit linear towers, in the face of high-altitude and cold environments, dual-circuit linear towers are prone to brittle fracture and snow-freeze-melt cycle damage, resulting in overall breakage and inability to be used again, leading to economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing double-loop straight-line towers, which suffer from brittle fracture and damage due to snow and ice melting cycles, resulting in overall breakage and unusability, leading to economic losses. Therefore, this invention proposes a straight-line tower resistant to cold regions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear tower resistant to cold regions, comprising a linear tower body and a tower head, wherein the linear tower body is fixedly connected to the tower head by bolts, the outer wall of the linear tower body is processed with a hot-dip galvanized anti-corrosion layer, the outer wall of the tower head is fixedly connected to a triangular crossarm by bolts, the lower end of the linear tower body is fixedly connected to a connecting leg, and the lower end of the connecting leg is connected to a reinforcing mechanism.

[0006] Preferably, the reinforcing mechanism includes a screw, the outer wall of which is threaded to a connecting leg, the outer wall of which is threaded to a screw block, the outer wall of which is threaded to a support seat, and the outer wall of which is threaded to a support column.

[0007] Preferably, the outer wall of the support column is fixedly connected to the cement column, and the lower end of the triangular crossbeam is connected to an installation mechanism.

[0008] Preferably, the installation mechanism includes a fixing rod, the upper end of which is fixedly connected to a triangular crossarm, the outer wall of which is fixedly connected to an insulator, and the end of which is fixedly connected to a conductor hanging point.

[0009] Preferably, the upper end of the cement column is fixedly connected to the cement base.

[0010] The present invention proposes a linear tower for high-altitude and cold-resistant regions, which has the following advantages: Cross-shaped support columns are inserted into concrete containing antifreeze to ensure stability between the support columns and support base and the ground; multiple nickel-based alloy bolts are used around the tower head and linear tower body for fixation; the linear tower body and tower head are made of Q345D steel to ensure resistance to brittle fracture at low temperatures; and the surfaces of the linear tower body and tower head are treated with a hot-dip galvanized anti-corrosion layer to resist snow melting corrosion and ice melting cycle damage, reducing the overall fracture of the linear tower body and tower head, and minimizing economic losses during use.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Please see Figure 1-6In this embodiment, a cold-resistant linear tower includes a linear tower body 1 and a tower head 2. The linear tower body 1 is fixedly connected to the tower head 2 by bolts. The outer wall of the linear tower body 1 is processed with a hot-dip galvanized anti-corrosion layer 3. The outer wall of the tower head 2 is fixedly connected to a triangular crossarm 4 by bolts. The lower end of the linear tower body 1 is fixedly connected to a connecting leg 5. The lower end of the connecting leg 5 is connected to a reinforcement mechanism 6.

[0020] The reinforcement mechanism 6 includes a screw 601, which is inserted into concrete containing antifreeze through a cross-shaped support column 604 to achieve the effect of reinforcing the support base 603 and the support column 604 with the ground. The outer wall of the screw 601 is threaded to the connecting leg 5, the outer wall of the screw 601 is threaded to the screw block 602, the outer wall of the screw 601 is threaded to the support base 603, and the outer wall of the support base 603 is threaded to the support column 604.

[0021] Cross-shaped support columns 604 are inserted into concrete containing antifreeze to ensure the stability of the support columns 604 and support base 603 with respect to the ground. Multiple nickel-based alloy bolts are used to fix the support columns 604 and 603 through the tower head 2 and the straight tower body 1. The straight tower body 1 and tower head 2 are made of Q345D steel to ensure resistance to brittle fracture at low temperatures. The surfaces of the straight tower body 1 and tower head 2 are treated with a hot-dip galvanized anti-corrosion layer 3 to resist snow melting corrosion and ice melting cycle damage, reduce the overall fracture of the straight tower body 1 and tower head 2, and reduce economic losses during use.

[0022] The outer wall of the support column 604 is fixedly connected to the cement column 7. The lower end of the triangular crossarm 4 is connected to the installation mechanism 8. The insulator 802 and the fixing rod 801 are fixedly installed by passing a bolt through the silicone rubber composite insulator 802. The installation mechanism 8 includes the fixing rod 801. The upper end of the fixing rod 601 is fixedly connected to the triangular crossarm 4. The outer wall of the fixing rod 801 is fixedly connected to the insulator 802. The end of the insulator 802 is fixedly connected to the conductor hanging point 803. The upper end of the cement column 7 is fixedly connected to the cement seat 9.

[0023] Working principle:

[0024] First, dig a pit to a depth of 1 to 1.5 meters in the ground. Pour concrete mixed with antifreeze into the pit, and simultaneously insert a cross-shaped support column 604 into the concrete. This allows the support column 604 and the cement column 7, which has solidified with antifreeze, to be deeply buried underground. Waterproof the surface of the support column 604. Then, screw the support base 603 into the support column 604. Finally, process the upper ends of the support column 604 and support base 603 into cement seats 9 to reinforce the support column 604 and support base 603 and ensure their stability with the ground. Similarly, waterproof the surface of the cement seat 9 again to reduce the possibility of rainwater seeping into the cement seat 9 and causing it to freeze and crack.

[0025] At this point, the linear tower body 1 containing the connecting leg 5 is inserted into the support base 603. A nickel-based alloy screw 601 passes through the support base 603 and the connecting leg 5, and a nickel-based alloy screw block 602 tightens the screw 601, thus fixing the linear tower body 1 at the upper end of the support base 603 and the connecting leg 5. The nickel-based alloy screw 601 and screw block 602 can precisely control the preload, preventing the linear tower body 1 from experiencing cold brittle fracture. Multiple linear tower bodies 1 are arranged using nickel-based alloy bolts to form a linear tower, and multiple nickel-based alloy bolts around the perimeter pass through the tower head 2 and the linear tower body 1 for fixation, strengthening the support of key nodes and preventing stress concentration in the tower head 2 and the linear tower body 1. Furthermore, the overall linear tower body 1 adopts a streamlined tower body and the tower head 2 has a triangular cross section, which can reduce wind resistance. The assembly of the overall linear tower is completed. The linear tower body 1 and the tower head 2 are made of Q345D steel to ensure resistance to brittle fracture at low temperatures. The surfaces of the linear tower body 1 and the tower head 2 are processed with a hot-dip galvanized anti-corrosion layer 3 to resist snow melting corrosion and ice melting cycle damage. At this time, the fixing rod 801 passes through the triangular crossarm 4, and bolts are used to pass through the silicone rubber composite insulator 802 and the fixing rod 801 to fix the insulator 802 and the fixing rod 801. The silicone rubber composite insulator 802 can resist frost cracking and does not accumulate snow. The conductor hanging point 803 at the lower end of the insulator 802 can be used to suspend the conductor.
