Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, and in particular to a steel pipe pole for power transmission towers. Background Technology

[0002] The steel pipe poles used for power transmission towers mainly refer to the main supporting members of power transmission towers.

[0003] Chinese Patent Publication No. CN 220889702 U discloses a steel pipe pole for power transmission towers, comprising a first steel pipe pole, a second steel pipe pole, a connecting assembly disposed between the first and second steel pipe poles, and a ventilation assembly disposed at the upper end of the second steel pipe pole. This utility model solves the problem that existing steel pipe poles for power transmission towers are connected by flanges, and in winter, rainwater can seep in through the gaps, freezing the studs and causing them to rust. This utility model, through the setting of a first annular sealing block, a second annular sealing block, a first annular groove, and a second annular groove, seals the gap between the first connecting plate and the second connecting plate, preventing rainwater from reaching the inside of the steel pipe pole through the gaps. It also prevents rainwater from seeping through the gaps to the outside of the studs in winter, freezing and causing the studs to rust, thus increasing the overall service life.

[0004] While the aforementioned patents can increase the service life of steel pipe poles for iron towers to some extent, some water droplets may remain on the inner wall surface of the pole due to their small mass when the water vapor inside the pole condenses into water droplets in summer. This can cause the pole in that area to become damp and rust. In addition, the aforementioned patents only open strip-shaped ventilation openings at the top of the tower, which cannot guarantee the overall airflow within the pole. As a result, it is not possible to quickly evaporate the water remaining inside the pole. Therefore, the actual effect may not be ideal in practical use.

[0005] Therefore, it is necessary to provide a new type of steel pipe pole for power transmission towers to solve the above-mentioned technical problems. Summary of the Invention

[0006] This utility model provides a steel pipe pole for power transmission towers, which solves the technical problem that the above-mentioned patents cannot make the condensed water inside the pole evaporate quickly, nor can they make the water droplets condensed on the inner wall of the pole fall down and be discharged quickly.

[0007] To solve the above-mentioned technical problems, the present invention provides a steel pipe pole for power transmission towers, comprising multiple vertically arranged pole bodies connected end to end and an air intake mechanism;

[0008] The air intake mechanism is located at the top of the uppermost rod.

[0009] The air intake mechanism includes a connecting plate fixedly connected to the top of the rod body. Multiple air guide plates are vertically fixedly connected to the upper surface of the connecting plate. A cover plate is horizontally fixedly connected to the top of the multiple air guide plates. An air intake fan is vertically rotatably connected to the lower surface of the cover plate. A motor housing is fixedly connected to the top of the cover plate. A motor is vertically fixedly connected inside the motor housing. The output shaft of the motor rotatably passes through the cover plate and is fixedly connected to the top of the rotating shaft of the air intake fan. A through hole adapted to the inner diameter of the rod body is vertically opened on the lower surface of the connecting plate.

[0010] Preferably, flanges are fixedly connected to the top and bottom of the plurality of rods, and the plurality of rods are interconnected by the flanges.

[0011] Preferably, the outer edge of the outer end surface of the plurality of flanges is provided with an annular groove, and a sealing ring is provided inside the plurality of grooves.

[0012] Preferably, a plurality of reinforcing ribs are fixedly connected between the outer surfaces of the plurality of rods and the outer surface of the flange thereon.

[0013] Preferably, the inner surfaces of the plurality of rods are provided with a plurality of curved guide grooves along their length direction, and the plurality of guide grooves are evenly spaced along the circumferential direction of the cross-section of the rod.

[0014] Preferably, each of the lower rods has a funnel whose outer diameter matches the inner diameter of the rod fixedly connected inside. The bottom of each funnel is connected to a drain pipe, and the other end of each drain pipe passes through the outer surface of the rod and extends outward.

[0015] Compared with related technologies, the steel pipe pole for power transmission towers provided by this utility model has the following beneficial effects: This utility model provides a steel pipe pole for power transmission towers, which, by setting an air intake mechanism and a guide channel, has an air intake mechanism set at the top of the uppermost pole body. The air intake mechanism continuously supplies air into the interior of the pole body, ensuring that the airflow inside the pole body is always in a flowing state, accelerating the evaporation of condensed water inside the pole body. In addition, a guide channel is also set inside the pole body, which allows the condensed water droplets to quickly flow down the guide channel and finally be discharged through the funnel and drain pipe, avoiding water droplets from staying for a long time, thereby further improving the service life of the pole body.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the steel pipe pole for power transmission towers provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal flow channel structure of the steel pipe pole used for power transmission towers. Figure 3 for Figure 1 The diagram shows the structural schematic of the air intake mechanism for the steel pipe pole used in power transmission towers. Figure 4 for Figure 1 The diagram shows the structure of the funnel and drainage pipe in the steel pipe pole for power transmission towers. The steel pipe pole for power transmission towers includes: multiple vertically arranged pole bodies 1 connected end to end and an air intake mechanism 4;

[0023] The air intake mechanism 4 is located at the top of the uppermost rod 1;

[0024] The air intake mechanism 4 includes a connecting plate 41 fixedly connected to the top of the rod 1. Multiple air guide plates 42 are vertically fixedly connected to the upper surface of the connecting plate 41. A cover plate 43 is horizontally fixedly connected to the top of the multiple air guide plates 42. An air intake fan 45 is vertically rotatably connected to the lower surface of the cover plate 43. A motor housing 44 is fixedly connected to the top of the cover plate 43. A motor is vertically fixedly connected inside the motor housing 44. The output shaft of the motor rotatably passes through the cover plate 43 and is fixedly connected to the top of the rotating shaft of the air intake fan 45. A through hole adapted to the inner diameter of the rod 1 is vertically opened on the lower surface of the connecting plate 41.

[0025] The device can keep the air flowing inside the rod body through the air intake mechanism 4. The air intake mechanism 4 is driven by a motor to rotate the air intake fan 45. During the rotation, it can draw outside air into the inside of the rod body 1, so that outside air can flow continuously from the top of the rod body 1 to the bottom. This can accelerate the evaporation of condensed water inside the multiple rod bodies 1, prevent the inside of the rod body 1 from rusting, and improve the overall stability and service life of the rod body 1.

[0026] The motor housing 44 is a protective structure that protects the motor.

[0027] The top and bottom of multiple rods 1 are fixedly connected to flanges 2, and the multiple rods 1 are interconnected through flanges 2.

[0028] Annular grooves 3 are provided on the outer edge of the outer end surface of multiple flanges 2, and sealing rings are provided inside the multiple grooves 3.

[0029] The rods 1 are connected to each other by flanges 2. This structure is convenient to install and is a commonly used existing technology. The sealing ring is made of rubber and its outer end protrudes from the outer surface of the flange 2. After the two flanges 2 are connected to each other, they can achieve a sealing effect and prevent moisture from entering.

[0030] Multiple reinforcing ribs 6 are fixedly connected between the outer surfaces of multiple rods 1 and the outer surfaces of flanges 2 on them.

[0031] The reinforcing rib 6 strengthens the connection and improves the overall stability of the device.

[0032] Multiple curved guide grooves 5 are formed on the inner surface of multiple rods 1 along their length direction, and the multiple guide grooves 5 are evenly spaced along the circumferential direction of the cross section of the rods 1.

[0033] The guide groove 5 allows water droplets condensed inside the rod 1 to slide off quickly, preventing water droplets from adhering to the inside of the rod 1 for a long time and causing the inner surface of the rod 1 to rust.

[0034] The lower rods 1 are all fixedly connected to funnels 7 whose outer diameter matches the inner diameter of the rods 1. The bottom ends of the funnels 7 are connected to drain pipes 8, and the other ends of the drain pipes 8 pass through the outer surface of the rods 1 and extend outward.

[0035] Water droplets that slide down from inside the rod 1 will eventually collect through the funnel 7 and be discharged to the outside of the rod 1 through the drain pipe 8.

[0036] The working principle of the steel pipe pole for power transmission towers provided by this utility model is as follows:

[0037] The device ensures constant airflow inside the rod body through the air intake mechanism 4. The air intake mechanism 4 is driven by a motor to rotate the air intake fan 45, which draws outside air into the rod body 1 during rotation. This allows outside air to flow continuously from the top of the rod body 1 to the bottom, thereby accelerating the evaporation of condensed water inside the multiple rod bodies 1, preventing rust inside the rod body 1, and improving the overall stability and service life of the rod body 1. The guide groove 5 allows the water droplets inside the rod body 1 to slide off quickly, preventing the water droplets from adhering to the inside of the rod body 1 for a long time and causing the inner surface of the rod body 1 to rust.

[0038] Compared with related technologies, the steel pipe pole for power transmission towers provided by this utility model has the following beneficial effects: This utility model provides a steel pipe pole for power transmission towers. By setting an air intake mechanism 4 and a guide channel 5, the air intake mechanism 4 is set at the top of the uppermost pole body. The air intake mechanism 4 continuously supplies air into the interior of the pole body 1, ensuring that the airflow inside the pole body 1 is always in a flowing state, accelerating the evaporation of condensed water inside the pole body 1. Furthermore, a guide channel 5 is also set inside the pole body 1, which allows the condensed water droplets to quickly flow downwards along the guide channel 5 and finally be discharged through the funnel 7 and the drain pipe 8, avoiding water droplets from staying for a long time, thereby further improving the service life of the pole body.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
