Description

Technical Field

[0001] The invention relates to the technical field of power transmission line structures, in particular to a hoop-type connection transmission tower angle steel reinforcement device. Background Art

[0002] Transmission towers are structures used to support power transmission lines. They are usually made of metal or concrete and have sufficient strength and stability to support the conductors, insulators and other equipment of high-voltage power lines. Transmission towers play an important role in the transmission system, enabling the efficient transmission of electricity generated by power plants to users or other transmission facilities. These towers are usually designed and arranged in different locations and forms according to the needs of power lines and terrain conditions.

[0003] During use, as a wind-sensitive structure, the transmission tower has the characteristics of high flexibility and low resistance, which makes it extremely susceptible to damage or even collapse due to wind loads. Under the action of lateral wind loads, the components mainly bear tension, eccentric pressure, and lateral bending moment. Pole towers are usually destroyed in extreme weather conditions (such as strong tornadoes, local strong convection, and local strong winds caused by special terrain and micro-meteorological conditions). The wind pressure exceeds the design conditions. On the one hand, the tensile and compressive stresses on certain sections of the tower are greater than the yield limit of the material. On the other hand, due to the different flexibility of each surface of the angle steel and the anisotropy of the turning radius, it is not conducive to the stability of the compression rod along the weak axis. The resulting torsional deformation will cause large torsional stress in the rod, and the local compression rod of the tower body will be buckled and unstable and destroyed. Further development will cause local bending of the tower, leading to the destruction of the tower. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 , which is the first embodiment of the present invention, and provides a clamp-type connection transmission tower angle steel reinforcement device, which can improve the overall wind resistance of the tower, and includes an installation component 100, including a main material 101, a reinforcement component 102 movably connected to the main material 101, a connection component 103 movably connected to the reinforcement component 102, the connection component 103 enables the reinforcement component 102 to be fixedly connected to the main material 101, an insertion component 104 movably connected to the connection component 103, the insertion component 104 enables the reinforcement component 102 to be quickly connected, and a fixing component 105 movably connected to the insertion component 104;

[0034] The locking component 200 can observe the locking degree of the reinforcement component 102, and includes a rotating component 201 movably connected in the connecting component 103, and an observation piece 202 arranged in the rotating component 201.

[0035] In summary, the present invention provides a CPRP-connected transmission tower angle steel reinforcement structure based on the wind load factor and stress angle of the tower, and uses the super-strong tensile elasticity and fatigue resistance of the CFRP material to reduce the generation of structural stress. At the same time, the clamp type allows the reinforcement material 102a and the main material 101 to coordinate the overall stress and the stress is uniform and continuous, thereby enhancing the tower's wind resistance, effectively improving the overall strength of the tower, and avoiding instability and deformation.

[0036] Example 2

[0037] Reference Figures 1 to 3, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a hoop-type connection transmission tower angle steel reinforcement device, which solves the problem that the transmission tower is easily damaged or even collapsed by wind load. It includes the reinforcement component 102 including a reinforcement material 102a arranged on one side of the main material 101, and two groups of connectors 102b arranged on one side of the reinforcement material 102a. The connector 102b is a newly designed CFRP angle steel connector 102b. The CFRP material is a composite material composed of carbon fiber and resin matrix. It has higher tensile strength and rigidity than steel. When the transmission tower is subjected to lateral wind pressure, the super tensile elasticity and fatigue resistance of the reinforced connector 102b can well absorb the impact energy and reduce the tension and stress on the cross section of the tower main material 101. In addition, the reinforcement structure is a hoop type with good continuous penetration, which makes the overall flexibility of the structure the same, reduces the torsional stress, and avoids the bending instability of the component around the weak axis. At the same time, by improving the tower body coefficient and the windward surface projection area, the tower wind load standard value is increased, and the overall wind resistance of the tower is effectively improved. At the same time, the reinforcement structure of the present invention is simple and convenient to construct, and it also greatly improves work efficiency on the basis of ensuring construction safety.

[0038] The connecting piece 102b is designed according to the parameters of the main material 101. Assuming that the side length of the main material 101 is a and the thickness is d, the outer hoop length of the connecting piece 102b is 1.42a, and the length d at the corner 102b-1 is 145°, and becomes a when the angle 102b-2 is a right angle of 90°, which can fit the main material 101 and the reinforcement material 102a well to ensure the synergistic performance of the two.

[0039] Furthermore, the reinforcing material 102a and the main material 101 are back to back to form a cross-shaped cross section.

[0040] Furthermore, the connecting member 102b is provided with a corner 102b-1, the degree of the corner 102b-1 is a right angle of 90°, an angle 102b-2 is provided on one side of the corner 102b-1, and a circular hole 102b-3 is opened.

[0041] In summary, according to the overhead transmission line load specification "DL / T 5551-2018", the tower wind load calculation formula is, where is the building shape coefficient, is the tower wind vibration coefficient at height z, is the tower component icing wind load increase coefficient, and is the projected area calculation value of the windward component. As mentioned above, the variable force influencing factors of the tower are the shape coefficient and the windward construction projected area. For towers composed of steel (angle steel, channel steel, I-beam and square steel) components, 1.3(1+η) should be taken, and η is the tower leeward wind load reduction coefficient, which should be taken according to the provisions of the table below.

[0042]

[0043] Where: A-tower outline area; a-tower windward width; b-the distance between the tower windward and leeward sides.

[0044] The present invention is a hoop-type structure, which surrounds the main material 101 and the auxiliary material from the outside in a cross-shaped connection and fixation in the most stable structure. The structural shape is tightly around the main and auxiliary materials, does not increase the tower outline area, increases the tower's windward width, thereby increasing the tower's wind load and enhancing the tower's wind resistance. In addition, most angle steel reinforcement devices have segmented structures, a large number of connectors 102b, and the material of the connectors 102b is steel, which has poor toughness and weak integrity. The reinforcement force is discontinuous, resulting in uneven force at the disconnection point, the highest stress ratio, and a risk point for overall structural damage.

[0045] The present invention provides a CPRP-connected transmission tower angle steel reinforcement structure based on the wind load factor and stress angle of the tower, and uses the super-strong tensile elasticity and fatigue resistance of CFRP materials to reduce structural stress. At the same time, the clamp type allows the reinforcement material 102a and the main material 101 to be coordinated as a whole and the stress is uniform and continuous, thereby enhancing the tower's wind resistance, effectively improving the overall strength of the tower, and avoiding instability and deformation.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3

[0048] Reference Figures 4 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a clamp-type connection transmission tower angle steel reinforcement device, which solves the problem of installing the connecting piece 102b. It includes the connecting component 103 including a mounting sleeve 103a fixedly connected to the circular hole 102b-3, the mounting sleeve 103a is adapted to the circular hole 102b-3, and a connecting pipe 103b slidably connected to the mounting sleeve 103a, a slide groove 103c opened at one end of the connecting pipe 103b, and two sets of sliding plates 103d slidably connected to the slide groove 103c.

[0049] Furthermore, the installation component 104 includes a hinged rod 104a hinged on the two groups of sliding plates 103d, a movable rod 104b movably connected to the hinged rod 104a, the movable rod 104b is made of a deformable material, and a limit block 104c fixed to the movable rod 104b, wherein the two groups of hinged rods 104a can be made vertical or horizontal through the movable hinged rod 104a, and when the two groups of hinged rods 104a are in a vertical state, they can pass through the installation sleeve 103a together with the limit block 104c.

[0050] Furthermore, the fixing assembly 105 includes extrusion plates 105a movably connected to both sides of the sliding plate 103d, the extrusion plates 105a are installed in the installation sleeve 103a, and threads 105b are provided in the limiting block 104c.

[0051] The rotating assembly 201 includes a screw rod 201a rotatably connected to the mounting sleeve 103a, and a pressure rod 201b movably connected to the screw rod 201a, and the pressure rod 201b is fixed to the limiting block 104c.

[0052] Furthermore, the screw rod 201a is connected to the thread 105b of the extrusion plate 105a.

[0053] Among them, when the operator passes the screw rod 201a through the connecting tube 103b, the end of the screw rod 201a passes through the middle of the limit block 104c, and when the screw rod 201a continues to move forward, it drives the limit block 104c and the hinge rod 104a to rotate in the slide groove 103c. During the rotation, the limit block 104c moves on the screw rod 201a. When the limit block 104c gradually approaches the slide groove 103c, the limit block 104c is pressed down, and the movable rod 104b is used to drive the hinge rod 104a to be horizontal. When the hinge rod 104a is horizontal, one side of the hinge rod 104a is in contact with the side wall of the installation sleeve 103a, and the two ends of the installation sleeve 103a are fixed on both sides of the circular hole 102b-3, so that the two sets of connecting parts 102b are tightly fixed.

[0054] When the limiting rod is pressed down, the pressing rod 201b is driven to move simultaneously. During the movement, the pressing rod 201b presses the pressing plate 105a, and the pressing plate 105a and the limiting block 104c exert force on each other, so that the mounting sleeve 103a is fixed more firmly.

[0055] Furthermore, the observation member 202 includes a cavity 202a opened on the screw 201a, and a latch rod 202b arranged in the cavity 202a, the end of the latch rod 202b is colored, when the operator gradually tightens the screw 201a, the screw 201a extends, the cavity 202a is provided with a light-absorbing solution, the latch rod 202b is away from the top of the screw 201a, the light-absorbing solution flows in, then when the color of the end of the latch rod 202b is dark, the screw 201a is tightened, and when the bolt is loosened, the end is light-colored.

[0056] In summary, the operator can judge whether the two groups of connecting members 102b are firmly connected by observing the color of the end of the latch rod 202b.

[0057] The remaining structure is the same as that of Example 2.
