Description

Technical Field

[0001] The utility model relates to the technical field of power transmission towers, in particular to a small-root-opening combined power transmission tower. Background Art

[0002] The transmission tower is the supporting point of the overhead line. If one circuit is set up on the transmission tower, it is a single-circuit transmission tower, and if two circuits are set up on the transmission tower, it is a double-circuit transmission tower. A single circuit refers to a circuit in which one load has one power supply; a double circuit refers to a circuit in which one load has two power supplies. Generally, enterprises with high requirements for power supply reliability or important regional substations use double-circuit power supply, which can protect one of the power supplies from power outages for some reason, while the other power supply can continue to supply power. However, for general small and medium-sized users who do not require high power supply reliability, single power supply is often used. For example, a small-root-opened combined transmission tower with application number CN219864358U is specifically a small-root-opened combined transmission tower. The utility model discloses a transmission tower, comprising a tower head, a tower body and a tower foot connected in sequence, wherein the tower head is made of an angle steel component, and the main materials of the tower body and the tower foot are made of steel pipe components. The tower head comprises a tower head middle column, a ground wire bracket and at least two cross arms arranged from the tower head middle column from top to bottom, and the tower head middle column is connected to the tower body through an adapter flange, and a stiffening plate is arranged between the bottom of the adapter flange and the tower body; one side of the adapter flange protrudes outward to form a convex plate, and a plurality of angle steel mounting holes are arranged on the convex plate, and a reinforcing stiffening plate extending to the edge of the convex plate is arranged at the bottom of the convex plate and connected to the tower body; the tower body and the tower foot are connected through a flange plate, and a stiffening plate is arranged between the bottom of the flange plate and the tower foot. The utility model solves the technical problem that the existing urban narrow-base transmission tower has limited bearing capacity for high-voltage transmission lines;

[0003] Transmission towers are tall structures that are very sensitive to tilt and deformation, and have high requirements for uneven foundation settlement. Common structural forms of transmission tower foundations include independent foundations, expanded foundations, and pile foundations. The structural form of transmission towers mainly adopts steel structures. Conventional transmission towers and foundation structures are difficult to adapt to the surface movement and deformation of coal mine goafs, which may cause the transmission tower to deflect or even overturn.

[0004] At present, when installing transmission towers with external cables, in order to ensure the stability of the cables, most of them adopt rigid fixation. However, in order to prevent the cables from breaking due to being too tight, a certain margin will be left. When the cables shake due to external wind force, the connection position between the cables and the tower body will be subjected to long-term continuous friction due to the rigid fixation. With years of use, the connection position will be worn and damaged, which will increase the risk of accidents and bring inconvenience to the staff. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a combined transmission tower with a small root opening, which solves the problem that when the current transmission tower is installed with external cables, in order to ensure the stability of the cables, most of them adopt rigid fixation, but in order to prevent the cables from breaking due to being too tight, most of them will leave a certain margin. When the cables shake due to external wind force, the connection position between the cables and the tower body will be subjected to long-term continuous friction due to the rigid fixation. With years of use, the connection position will be worn and damaged, which will increase the risk of accidents, thereby causing inconvenience to the staff.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] At present, when installing transmission towers with external cables, in order to ensure the stability of the cables, most of them are rigidly fixed. However, in order to prevent the cables from breaking due to being too tight, a certain margin is usually left. When the cables shake due to external wind force, the connection position between the cables and the tower body is rigidly fixed, which makes the connection position subject to long-term continuous friction. With years of use, the connection position will be worn and damaged, which will increase the risk of accidents, thus bringing inconvenience to the staff.

[0022] In view of this, the utility model provides a combined transmission tower with a small opening. Through the cooperation of the tower frame, the first reinforcement frame, the second reinforcement frame, the cross arm and the installation device, the installed external cables can be buffered and protected to avoid the wear of the connection position due to the long-term shaking of the cables, thereby greatly improving the quality and service life of the cables, and facilitating the use of the staff.

[0023] Embodiment 1: By Figure 1 , 2 , 3 and 4 show that a small-root combined transmission tower includes a tower frame 1, a plurality of cross arms 6 are installed on the top of the tower frame 1, and the small-root combined transmission tower also includes: a mounting device 2, which is installed on both sides of the plurality of cross arms 6; a reinforcement device 3, which is arranged below the tower frame 1; wherein the mounting device 2 can provide buffer protection for the installed cables, and the reinforcement device 3 can improve the overall use stability of the small-root combined transmission tower;

[0024] In the specific implementation process, it is worth pointing out that the installation device 2 can protect the connected cables, thereby preventing the cables from being worn due to long-term shaking, and the reinforcement device 3 can reinforce the small-rooted combined transmission tower, thereby ensuring the stability of use;

[0025] Furthermore, a plurality of first reinforcement frames 4 are installed on the outer wall of the tower 1, and a second reinforcement frame 5 is installed on the outer walls of the plurality of cross arms 6, and the outer walls of the plurality of second reinforcement frames 5 are fixedly connected to the upper part of the tower 1;

[0026] In the specific implementation process, it is worth pointing out that the first reinforcement frame 4 and the second reinforcement frame 5 can improve the overall strength of the small-root combined transmission tower;

[0027] Specifically, when using the combined transmission tower with a small opening, the staff first erects the tower 1 on the external foundation, and then the staff installs the reinforcement device 3 under the tower 1. Then the staff uses the installation device 2 to install the cable on the top of the combined transmission tower with a small opening, and then it can be put into use.

[0028] Embodiment 2: By Figure 1 , 2 As can be seen from Figure 3, the installation device 2 includes: a plurality of support rods 201, which are respectively installed on both sides of the plurality of cross arms 6; a plurality of first springs 202, which are respectively sleeved on the outer walls of the plurality of support rods 201 and respectively fixedly connected to the outer walls of the plurality of cross arms 6; a plurality of sleeves 203, which are respectively sleeved on the outer walls of the plurality of support rods 201 and respectively fixedly connected to the bottoms of the plurality of first springs 202; a plurality of vertical tubes 204, which are respectively sleeved on the bottoms of the plurality of support rods 201; a plurality of second springs 205, which are respectively sleeved on the bottoms of the plurality of support rods 201; They are respectively installed on the inner walls of multiple vertical tubes 204 and respectively abut against the bottoms of multiple support rods 201; multiple first installation tubes 206 are provided, which are respectively installed on the outer walls of multiple sleeves 203 and multiple vertical tubes 204; multiple second installation tubes 207 are provided, which are respectively installed on the outer walls of multiple first installation tubes 206; wherein the first installation tube 206 and the second installation tube 207 can install and fix external cables, and the first spring 202 and the second spring 205 and other components can buffer and protect the shaking cables;

[0029] In the specific implementation process, it is worth pointing out that the first spring 202 and the second spring 205 can provide buffer protection for the cable when the cable shakes, thereby preventing the cable from being worn at the connection position between the cable and the small-opening combined transmission tower;

[0030] Furthermore, the inner walls of the first mounting tube 206 and the second mounting tube 207 are both installed with rubber pads;

[0031] In the specific implementation process, it is worth pointing out that the rubber pad can increase the friction between the first mounting tube 206 and the second mounting tube 207 and the support rod 201, thereby consuming the elastic potential energy generated when the first spring 202 and the second spring 205 are deformed;

[0032] Specifically, based on the above-mentioned embodiment 1, when installing the cable, the staff opens the second mounting tube 207, and then places the cable inside the first mounting tube 206 and the second mounting tube 207, and then fixes the first mounting tube 206 and the second mounting tube 207 with bolts. At this time, it can be put into use. When the cable shakes, the first mounting tube 206 and the second mounting tube 207 can drive the sleeve 203 or the vertical tube 204 to move along the outer wall of the support rod 201, and then drive the first spring 202 or the second spring 205 to deform. At this time, the first spring 202 or the second spring 205 can be used for buffering protection. At this time, the elastic potential energy of the first spring 202 or the second spring 205 can be consumed through the friction between the sleeve 203 or the vertical tube 204 and the support rod 201, so that the cable can be quickly stabilized.

[0033] Embodiment 3: By Figure 1 , 2 As can be seen from Figure 4, the reinforcement device 3 includes: a reinforcement pipe 301, which is provided in plurality and is installed below the tower 1; a first oblique rod 302, which is provided in plurality and is respectively installed on the outer walls of the plurality of reinforcement pipes 301; a second oblique rod 303, which is provided in plurality and is respectively installed on the outer walls of the plurality of reinforcement pipes 301; wherein the reinforcement pipe 301, the first oblique rod 302 and the second oblique rod 303 can improve the installation stability of the small-rooted combined transmission tower;

[0034] In the specific implementation process, it is worth pointing out that the reinforcement pipe 301 can surround and protect the lower part of the tower 1, and the first inclined rod 302 and the second inclined rod 303 can improve the connection stability and reinforcement strength between the reinforcement pipe 301 and the tower 1, and the reinforcement pipe 301, the first inclined rod 302 and the second inclined rod 303 are buried inside the ground pile together with the tower 1;

[0035] Specifically, based on the above-mentioned embodiments 1 and 2, when the tower 1 is reinforced, the staff will sleeve the reinforcement pipe 301 under the tower 1. When the tower 1 is subjected to force, the first diagonal rod 302 and the second diagonal rod 303 can share the external force exerted on the tower 1, thereby playing a reinforcing role.
