In the figure: the bird-proof tower head comprises a tower head main body 1, a first derivative truss structure 2, a camera 3, a second derivative truss structure 4, a telescopic bird-proof baffle 5, a guide rail 5.1, a scroll 5.2, a rolling sheet 5.3 and an insulator string 6.
Detailed Description
As shown in fig. 1-5, a tower head structure of a novel double-loop power transmission tower comprises a tower head main body 1, wherein first derivative truss structures 2 extend from the left side and the right side of the tower head 1 of a traditional tower under the condition that the main material of the tower is not changed, and the first derivative truss structures 2 are in a herringbone shape. The material of the first derivative truss structure 2 is composed of angle steel, providing a special support for suspending the more commonly used "ball-striking" cameras 3, and leaving room for ancillary equipment such as: and (4) placing a solar photovoltaic cell panel.
The front side and the rear side of the tower head main body 1 are also provided with second derivative truss structures 4 extending out of the cross arm main material on the iron tower, the second derivative truss structures 4 are triangular truss structures, and the triangular truss structures are mainly used for installing on-line monitoring equipment or other facilities such as microclimate sensors, tower body inclination sensors, wire icing monitoring devices and the like commonly used for on-line monitoring of the existing power transmission lines.
As shown in fig. 6-7, in addition, in order to cope with the increasingly severe bird prevention problem of the transmission line, a retractable bird prevention baffle 5 based on the shutter principle is installed at the insulator hanging point of the transmission tower. The telescopic bird-preventing baffle 5 is made of metal materials and mainly comprises a guide rail 5.1 and a scroll 5.2 which are additionally arranged on a cross arm of an iron tower. The rolling sheet 5.3 is wound on the reel 5.2, and the left and right extending parts are limited by the guide rails 5.1. When birds stop on the cross arm, because the bird baffle shields the insulator string below the cross arm, bird droppings can not drop on the insulator, the probability of insulator pollution flashover is greatly reduced, and the power supply reliability of the power transmission line is ensured.
The working process and principle are as follows: the herringbone structure of the tower head of the iron tower can well meet the installation requirement of the ball-hitting camera which is widely applied at present, as shown in figure 8. The biggest advantage of "ball hits" camera is in can 360 rotations to because the camera is in the tower head directly over the reason, the camera field of vision is very good, can cover this basic iron tower's size side passageway completely, through the outer broken and mountain fire condition that probably appear in the camera monitoring passageway, circuit fortune dimension personnel can also adjust the focus of camera, observe some defects that exist on the iron tower, such as: the glass insulator is burst, and bird nests exist on the iron tower. The ball-hitting camera is arranged on the herringbone truss, so that the situation that equipment can only be arranged at the mouth of the iron tower or the cross arm due to the fact that the tower head part does not have a proper position cannot occur, the iron tower partially shields the visual field of the camera, the position of the mouth is low, and some potential safety hazards in the channel and the defects on the iron towers on the large-size side and the small-size side cannot be observed possibly.
The triangular structure of iron tower front and back both sides is used for laying some other on-line monitoring sensors specially, and is more common to have: the micro-meteorological sensor, the tower body inclination sensor and the like have no special positions for the installation of the sensors on the iron tower at present and have no uniform specification. The triangular structure extends from the center of the upper cross arm of the iron tower, so that the installation platform for various sensors is provided, particularly for microclimate sensors, the wind speeds of the tower body and the tower head are often different due to the height difference, and the wind speed of the tower head is generally higher than that of other parts. The microclimate sensor is mounted on the platform, so that the wind speed at the tower head can be directly measured, and the data is more representative.
The retractable anti-bird baffle of insulator hanging point department, when not carrying out the circuit maintenance, the personnel need not go up and down insulator chain, can close the baffle (expand roll up curtain piece 5.3), as shown in figure 7, insulator hanging point top is owing to there being the protection of baffle this moment, when birds perch or stop in iron tower cross arm department, can prevent that bird's droppings or other filth from dropping on the insulator piece, and the maximum probability has reduced the emergence of insulator pollution flashover accident. When carrying out circuit maintenance work, insulator chain about the maintainer needs, as shown in fig. 6, open the lock of baffle through the key, pack up the roll up curtain piece through the pivot, insulator chain about the staff just can be smooth this moment, after maintenance work, close and lock the baffle by last staff.
