Description

A cable self-rescue device for mountain area

technical field

The invention belongs to the field of electric safety equipment, in particular to a cable self-rescue device for mountain areas.

Background technique

With the development of electric power, cables of different specifications are erected in the streets and alleys in China. Cables are used as channels for power transmission, and they are all over the country. In the process of using electricity in mountainous areas, the factors that are affected by the environment are relatively large, and natural disasters such as landslides or mudslides often occur in mountainous areas.

The erection of cables in mountainous areas usually uses telephone poles as support devices to escort long-distance power transmission. However, when mudslides or landslides occur in mountainous areas, the telephone poles are buried under the ground, so it is easy to fall down with landslides or mudslides. The cables on the utility poles were then stretched, causing power outages and affecting residents' electricity use.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a cable self-rescue device for mountain areas to solve the problem that the cable is broken due to the sliding of the electric pole when the landslide or debris flow occurs in the mountain area.

The significant beneficial effects achieved by the present invention:

1. A cable self-rescue device for mountainous areas of the present invention includes a utility pole and an automatic firing device, the utility pole includes a rod body and a cover body that is inserted into the rod body, and the automatic firing device includes a spring and a pressure ball; The spring is vertically arranged below the striker, and the pressure ball is set above the strike plate at the upper end of the spring. After the pole is tilted, the pressure ball rolls away from the strike plate due to the problem of angle deviation, and the pressure ball diameter is the same as that of the strike plate. The sum of the diameters of the springs is smaller than the diameter of the rod body, so that the pressure ball can be completely separated from the strike plate, so as not to affect the bounce of the spring; the distance between the strike plate and the striker rod is less than the extension length of the spring, which can make the strike plate when the spring bounces. An upward force is generated on the striker rod, so that the striker rod and the cover body are separated from the rod body, and the cable is fixed on the cover body when in use. The tensile force of the rear cable itself can play a supporting role to prevent the cable from breaking or being stretched when the utility pole falls; The pole falls and is stretched, which effectively solves the problem that the cable is stretched and broken due to the falling of the utility pole when a landslide or debris flow occurs in the mountainous area.

2. In order to prevent the cover body from shaking at the upper end of the rod body or being taken away from the rod body by the wind, an annular limit plate is fixedly connected to the rod body, and the striker is inserted into the annular limiter, and the position of the striker is generated by the setting of the annular limiter A certain limit function prevents the cover from shaking or being taken away from the rod by the wind.

3. In order to further increase the stability of the cover body on the rod body, a hole is provided on the striker rod, and a pin shaft is inserted into the hole. The pin shaft position is located under the annular limit plate, and the stability of the striker rod is increased by the setting of the pin shaft. The first guide wheel and the second guide wheel arranged on the inner wall of the rod can facilitate the movement of the rope. When the spring bounces, the strike plate drives the rope to move, and the rope moves between the second guide wheel and the first guide wheel. The pin shaft is pulled away from the hole on the draw rod under the restriction of a guide wheel, and the pin shaft will not be affected when the strike plate collides with the draw rod through the arrangement of the rope, the first guide wheel and the second guide wheel.

4. In order to make the draw rod leave the rod body smoothly, a lubricating layer is arranged between the annular restriction plate and the draw rod. The setting of the lubricating layer reduces the resistance generated when the draw rod leaves the annular restricting plate, so that the draw rod quickly leaves the rod body, Complete the separation of the cover body and the rod body.

5. The pit in the center of the strike plate is used to limit the pressure ball, to prevent the pressure ball from leaving the strike plate when the rod body undergoes a slight angle change, and misfire occurs.

6. Because the spring is flexible, in order to prevent the spring from tilting or bending, a spring sleeve is attached to the spring jacket, and the spring is restricted by the spring sleeve to prevent the spring from tilting or bending, which affects the striker's strike against the striker. impact strength.

7. The support rods that are evenly distributed in an annular shape on the outer peripheral surface of the spring sleeve can support the spring sleeve, and prevent the spring sleeve from tilting when the spring sleeve is inclined, which plays a supporting and stable role.

8. In order to facilitate the staff to find the position of the cover and the fall of the telephone pole, a smoke bomb is installed at the lower end of the cover. The pull ring of the smoke bomb is fixedly connected with the annular limit plate, and the smoke bomb follows when the cover leaves the pole. When it is opened, the staff can observe the number of falling power poles and confirm the position of the cover from a distance through the amount of smoke, which is convenient for estimating the damage caused by landslides and mudslides.

9. The reflective stickers set on the peripheral surface of the cover body can facilitate the staff to find the position of the cover body at night and support the cover body in time.

10. The maintenance port opened on the rod body is used to replace the spring to prevent the spring from losing its elasticity due to being pressed by the pressure ball for a long time, resulting in the failure of the automatic firing device.
