Description

Technical Field

[0001] The invention relates to the technical field of power transmission line maintenance, in particular to a bird nest cleaning device for power transmission lines. Background Art

[0002] Transmission lines are an important part of the power system, responsible for transmitting electricity generated by power plants to various power consumption areas. However, transmission lines are erected in the open air and are prone to becoming nesting sites for birds. Bird nests, if built on transmission towers or power lines, may cause multiple problems for power transmission. First, the weight of the bird's nest may cause a mechanical burden on the wires, affecting the stability and safety of the wires. Second, the materials in the bird's nest, such as branches, grass and other combustibles, increase the risk of electric shock and fire, especially in dry and hot conditions. In addition, birds and their nests may cause short circuits, especially in humid conditions, and feathers and urine nest materials may cause insulation performance to deteriorate and increase the failure rate.

[0003] In response to this problem, power companies usually take measures to clean bird nests on transmission lines. When workers use existing equipment to clean bird nests, due to the long cleaning rod, workers tend to get tired after holding the cleaning rod for a long time, resulting in low positioning accuracy of the cleaning rod during cleaning, which indirectly leads to low cleaning efficiency; the Chinese utility model patent with announcement number CN215645849U provides a bird nest auxiliary cleaning rack for transmission line maintenance, which has large resistance and low alignment accuracy when poking bird nests; the Chinese utility model patent with announcement number CN215580021U provides a transmission line tower bird nest cleaning device, which cannot guarantee the personal safety of personnel when lifting personnel.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Embodiment 1: This embodiment provides a bird nest cleaning device for a power transmission line, specifically, Figure 1 , Figure 2 As shown, it includes a lifting platform 1 and a cleaning assembly 2 installed on the lifting platform 1, the cleaning assembly 2 includes a supporting unit and a cleaning rod installed on the supporting unit, the cleaning rod includes a rod body and a rod head connected to the rod body, and the rod body is made of insulating material.

[0031] like Figure 3-Figure 8As shown, the rod head includes a cutting part and a puncture part, the puncture part includes a puncture head 211, the cutting part includes a cutting shell 210 and a cutting unit installed on the cutting shell 210, the puncture head 211 is detachably connected to the cutting shell 210, the cutting unit includes an active rod 212, a driven sleeve 213, a cutting knife 214, and a limiting shaft 215, the active rod 212 is fixedly connected to the driven sleeve 213, the driven sleeve 213 is rotatably connected to the cutting knife 214, the cutting knife 214 is provided with a notch, the rod head is provided with a through hole groove for the cutting knife 214 to move, the limiting shaft 215 is fixedly connected to the cutting shell 210, the limiting shaft 215 slides in the notch of the cutting knife 214, and the active rod 212 is moved along the axis of the rod head to realize the retraction and release of the cutting knife 214.

[0032] When it is necessary to clean the bird's nest, the staff stands on the lifting platform 1, and then the lifting platform 1 starts to rise. When the lifting platform 1 rises to a suitable position, the staff first pushes the active rod 212 toward the piercing head 211, so that the two cutting knives 214 are retracted into the rod head through the through hole groove, and then adjusts the position and angle of the cleaning rod, and then pushes the rod body to poke into the bird's nest with the rod head. Since the cutting knives 214 are retracted, the resistance of the rod head to pierce the bird's nest is small; when the rod head pierces the bird's nest, the staff pulls back the active rod 212, and at this time the active rod 212 drives the rod from The moving sleeve 213 moves synchronously, and the driven sleeve 213 pulls the cutting knife 214, so that the limiting shaft 215 slides in the slot, so that the cutting knife 214 rotates around the connection point between it and the driven sleeve 213, thereby extending the rod head. When the cutting knife 214 extends the rod head, the staff pulls the cleaning rod, at this time the bird's nest will block the cutting knife 214, and the cutting knife 214 cuts the bird's nest, causing the bird's nest to break; after multiple cuts until the bird's nest is completely broken and cleaned, the lifting platform 1 is lowered, and the staff leaves the lifting platform 1, completing the cleaning operation.

[0033] When cutting a bird's nest, if there are thicker branches or wires in the bird's nest that prevent the cutting knife 214 from cutting, the rod body is pushed so that the cutting knife 214 no longer contacts the obstacle, and then the active rod 212 is pushed so that the cutting knife 214 is retracted into the rod head, and then the rod body is pulled back, and then other areas are removed first, and finally it will be more convenient to clean up the thicker branches or wires.

[0034] The cutting knife 214 movably arranged on the rod head can retract into the rod head to reduce the puncture resistance when the rod head punctures the bird's nest; when the rod body is pulled back, the cutting knife 214 extends out of the rod head to cut and destroy the bird's nest, thereby improving the cleaning efficiency; if the resistance is large and the cutting cannot be completed, the cutting knife 214 is retracted into the rod head again, and then the cleaning rod is retracted to prevent the cutting knife 214 from being stuck in the bird's nest and unable to be retracted.

[0035] Embodiment 2: This embodiment further expands the cutting blade 214 on the basis of the embodiment 1. Figure 7 As shown, the cutting knife 214 is provided with an arched blade portion, and when cutting an object, the convergence point of the object is at the top of the arch.

[0036] Through the above arrangement, when the rod is pulled back, the branches in the bird's nest will gather at the arch apex. Compared with a straight blade, it can effectively prevent the branches from gathering at the intersection of the blade and the rod head, thereby improving the cutting efficiency.

[0037] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0038] Embodiment 3: This embodiment further expands the cutting unit on the basis of Embodiment 1. Figure 5-Figure 8 As shown, there are two cutting knives 214, and the two cutting knives 214 are arranged in parallel and staggered.

[0039] The two cutting knives 214 are arranged in parallel and staggered to prevent the cutting knives 214 from interfering with each other when they are retracted, thereby maximizing the blade length of the cutting knives 214 within the limited club head space to improve cutting efficiency.

[0040] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0041] Embodiment 4: This embodiment further expands the cleaning rod on the basis of embodiment 1, specifically as follows Figure 2-Figure 4 As shown, the rod body includes an outer shaft 209 and an inner shaft 208, the inner shaft 208 is threadedly connected to the outer shaft 209, the inner shaft 208 is rotatably connected to the active rod 212, a handle is provided at one end of the inner shaft 208 away from the active rod 212, and the outer shaft 209 is detachably connected to the cutting shell 210.

[0042] The staff member holds the handle on the inner shaft 208 with one hand and the outer shaft 209 with the other hand, and then rotates the handle to make the inner shaft 208 and the outer shaft 209 rotate relative to each other, so that the inner shaft 208 pulls or pushes the active rod 212, thereby realizing the retraction and extension of the cutting knife 214; when pulling the rod body to make the cutting knife 214 cut the bird's nest, the staff member holding the handle can also exert force better.

[0043] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Embodiment 5: This embodiment further expands the support unit on the basis of Embodiment 1. Figure 2As shown, the support unit comprises a group of a mounting seat 201, a support rod, and a ball sleeve rod 206. The mounting seat 201 is rotatably connected to the support rod. A clamping bolt 205 is provided on the mounting seat 201. The clamping bolt 205 cooperates with the support rod. The ball sleeve rod 206 is installed on the support rod. The ball pair on the ball sleeve rod 206 is connected to the ball center sleeve 207, and the rod is inserted into the ball center sleeve 207.

[0045] According to the position of the bird's nest, the staff first adjusts the angle of the support rod, and then tightens the clamping bolt 205 so that the limit shaft 215 presses the support rod to prevent the angle of the support rod from changing again; the ball sleeve rod 206 and the ball core sleeve 207 can be used to support the cleaning rod, and the support rod has a large range of motion, which does not affect the cleaning operation while providing support, greatly reducing the labor intensity of the staff.

[0046] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0047] Embodiment 6: This embodiment further expands the support rod on the basis of Embodiment 5. Figure 2 As shown, the support rod includes a first support rod 202, a second support rod 203, and a positioning pin 204. The second support rod 203 is slidably connected to the first support rod 202, and the positioning pin 204 is inserted between the first support rod 202 and the second support rod 203 to lock the length of the support rod.

[0048] The fulcrum position can be adjusted by adjusting the length of the support rod. The farther the fulcrum position is from the handle, the easier it is for the operator to operate. However, the movable stroke of the cleaning rod will also be reduced. Therefore, the length of the support rod can be adaptively adjusted according to the size of the bird's nest to save as much effort as possible while ensuring that the cleaning rod can completely penetrate the bird's nest.

[0049] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0050] Embodiment 7: This embodiment further expands the lifting platform 1 on the basis of the embodiment 1. Figure 1 , Figure 9-12As shown, the lifting platform 1 includes a chassis 111, on which a lifting frame is installed. The lifting frame includes a plurality of lifting rings 101, a connecting block 102, and a lifting connecting rod 103. The connecting block 102 is installed on the lifting ring 101, and the lifting connecting rod 103 is rotatably connected to the connecting block 102. Two longitudinally adjacent lifting connecting rods 103 are rotatably connected. A standing plate 110 is installed on a lifting ring 101 in the middle of the lifting frame; a gear is installed on the lifting connecting rod 103 at the bottom of the lifting frame. Wheel 104, the rotation center axis of the lifting link 103 coincides with the rotation center axis of the gear 104, the chassis 111 is rotatably connected to the volute gear disk 105, the gear 104 is meshed with the volute gear disk 105, the volute gear disk 105 is installed with a first bevel gear 108, the chassis 111 is rotatably connected to the crank handle 106, the crank handle 106 is installed with a second bevel gear 109, the second bevel gear 109 is meshed with the first bevel gear 108, and a plurality of rollers 107 are installed on the chassis 111.

[0051] By shaking the crank 106, the second bevel gear 109 drives the first bevel gear 108 to rotate, and the first bevel gear 108 drives the volute gear plate 105 to rotate. When the volute gear plate 105 rotates, multiple gears 104 rotate synchronously. The rotation of the gear 104 causes the lifting link 103 connected thereto to rotate synchronously, and the lifting link 103 in turn causes the connected lifting link 103 to rotate, thereby changing the spacing between the multiple lifting rings 101 to achieve the lifting and lowering of the lifting frame.

[0052] The standing board 110 installed in the middle of the lifting frame is for personnel to stand on, and the lifting ring 101 located on the upper part of the standing board 110 is used as a guardrail to prevent the staff from accidentally falling during the cleaning process.

[0053] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0054] Embodiment 8: This embodiment further expands the lifting platform 1 on the basis of Embodiment 7. Fig.11 As shown, the gear 104 is provided with a plurality of limiting holes, and a retaining bolt 112 is installed on the connecting block 102 , and the retaining bolt 112 is matched with the gear 104 .

[0055] When the height of the lifting frame is adjusted appropriately, the gear 104 tends to rotate due to the gravity of the lifting frame and the personnel. At this time, the teeth of the gear 104 press on the teeth of the volute gear plate 105, but the gear 104 cannot drive the volute gear plate 105 to rotate; when the retaining bolt 112 is turned so that the retaining bolt 112 is inserted into the limiting hole on the gear 104, the force that blocks the rotation of the gear 104 is transferred from the teeth to the retaining bolt 112, thereby improving the stress condition of the teeth and preventing the teeth from deforming.

[0056] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
