Description

一种手柄式低压接地棒A handle type low voltage ground rod

技术领域technical field

本发明涉及电力检修领域，更具体地，涉及一种手柄式低压接地棒。The invention relates to the field of electric power maintenance, and more particularly, to a handle-type low-voltage ground rod.

背景技术Background technique

低压接地棒是用于低压设备及低压线路停电检修时防止反送电造成人身伤害的一种安全用具。旧式低压接地棒，金属构建在绝缘棒顶部并连接有接地线，操作部位在绝缘棒底部，操作时，旋转绝缘棒操作部位控制金属构件松紧，使金属构件紧密接触检修设备或线路，达到接地目的。The low-voltage grounding rod is a safety device used to prevent personal injury caused by reverse power transmission when the low-voltage equipment and low-voltage lines are powered off and repaired. The old low-voltage grounding rod is constructed of metal on the top of the insulating rod and connected with a grounding wire. The operating part is at the bottom of the insulating rod. During operation, the operating part of the insulating rod is rotated to control the tightness of the metal components, so that the metal components are in close contact with the maintenance equipment or lines to achieve the purpose of grounding .

因为旧式低压接地棒金属构件在绝缘棒顶部重量较重，而操作部位重量较轻，造成旧式低压接地棒的重心偏向顶部，接地操作时需要双手转动绝缘棒操作部位，造成接地操作时难以固定金属构件位置，每次完成操作需要花很大力气和时间。并且金属构件每开合1厘米行程须约旋转绝缘棒5圈，操作较慢。Because the metal components of the old low-voltage grounding rod are heavy on the top of the insulating rod, while the weight of the operating part is light, the center of gravity of the old low-voltage grounding rod is deviated to the top, and the operating part of the insulating rod needs to be rotated with both hands during grounding operation, which makes it difficult to fix the metal during grounding operation. Component position, it takes a lot of effort and time to complete the operation each time. And the metal member needs to rotate the insulating rod about 5 times for every 1 cm stroke of opening and closing, and the operation is slow.

发明内容SUMMARY OF THE INVENTION

本发明为克服上述现有技术所述的至少一种缺陷，提供一种便捷的手柄式低压接地棒。The present invention provides a convenient handle-type low-voltage ground rod in order to overcome at least one of the above-mentioned defects in the prior art.

本发明旨在至少在一定程度上解决上述技术问题。The present invention aims to solve the above-mentioned technical problems at least to a certain extent.

本发明的目的是解决现有低压接地棒操作不便、费时的问题，以提高工作效率。The purpose of the present invention is to solve the problems of inconvenient and time-consuming operation of the existing low-voltage ground rod, so as to improve the work efficiency.

为了达到上述技术效果，本发明的技术方案如下：In order to achieve above-mentioned technical effect, technical scheme of the present invention is as follows:

When the handle 1 is held tightly, the movable part 11 of the handle 1 drives the pressing piece 7 to move, and the pressing piece 7 forms a certain angle with the vertical direction due to the pressure of the movable part 11 at the lower end, and presses the insulating rod 2 to move forward; when When the handle 1 is released, the contact part of the movable part 11 and the pressing piece 7 moves backward, the pressure on the pressing piece 7 disappears, and the pressing piece 7 returns to a vertical state and moves backward due to the elastic force of the second spring 8 .

另外，本实施例接地棒还包括第三弹簧10，所述第三弹簧10是压缩弹簧；所述第三弹簧10一端与所述扣板6连接，另一端与所述固定部12连接。当绝缘杆2向前移动时，扣板6会压缩第三弹簧10并松开绝缘杆2；当绝缘杆2停止向前移动时，扣板6因为第三弹簧10的弹力具有转动的趋势，并产生紧固绝缘杆2的力，使绝缘杆2无法向后移动；若一直按着扣板6压缩第三弹簧10，可以使绝缘杆2向后移动，使用过程方便。In addition, the ground rod in this embodiment further includes a third spring 10 , which is a compression spring; one end of the third spring 10 is connected to the gusset plate 6 , and the other end is connected to the fixing portion 12 . When the insulating rod 2 moves forward, the pinch plate 6 will compress the third spring 10 and release the insulating rod 2; when the insulating rod 2 stops moving forward, the pinch plate 6 has a tendency to rotate due to the elastic force of the third spring 10, And generate a force to fasten the insulating rod 2, so that the insulating rod 2 cannot move backward; if the third spring 10 is compressed by pressing the gusset 6 all the time, the insulating rod 2 can be moved backward, and the use process is convenient.

本实施例提供的手柄式低压接地棒，通过手柄1的开合移动绝缘杆2，从而控制活动夹片5逐级压紧接地线路，有效的加快了闭合速度；与传统的的旋转式接地棒相比，大大缩短了操作时间，并且更容易控制金属构件4的定位，使得作业更方便，增加了工作效率。The handle-type low-voltage grounding rod provided in this embodiment moves the insulating rod 2 through the opening and closing of the handle 1, so as to control the movable clip 5 to compress the grounding circuit step by step, effectively speeding up the closing speed; In comparison, the operation time is greatly shortened, and the positioning of the metal member 4 is easier to control, which makes the operation more convenient and increases the work efficiency.

实施例2Example 2

本实施例在上述实施例的基础上进一步优化和限定：This embodiment is further optimized and limited on the basis of the above-mentioned embodiment:

其中，金属构件4内部设有导向凸条，所述活动夹片5上设有与所述导向凸条配合的槽。活动夹片5根据导向凸条进行滑动，运动轨迹固定更易于控制。Wherein, the metal member 4 is provided with a guide protruding strip, and the movable clip 5 is provided with a groove for matching with the guiding protruding strip. The movable clip 5 slides according to the guide protruding strip, and the movement track is fixed and easier to control.

其中，绝缘杆2采用玻璃钢环氧树脂材料，耐压并且强度高。Among them, the insulating rod 2 is made of glass fiber reinforced plastic epoxy resin material, which has high pressure resistance and high strength.

另外，绝缘筒3外部设置有把手，方便携带。In addition, a handle is provided on the outside of the insulating cylinder 3, which is convenient to carry.

其中，接地螺母为防松螺母，防止接地线松动。Among them, the grounding nut is a locking nut to prevent the grounding wire from loosening.
