Description

Technical Field

[0001] The utility model relates to the technical field of grounding devices, and particularly relates to a grounding device for a distribution network. Background Art

[0002] A distribution network is a power grid that receives electric energy from a transmission network or a regional power plant and distributes it locally through distribution facilities or step by step according to voltage levels to various users. It is composed of lines, cables, poles, distribution transformers and other auxiliary equipment, and plays an important distribution role in the power grid. In the power grid system, a grounding device needs to be equipped. A grounding device refers to a grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment. The outer shell of an electrical equipment, including the cable sheath, must be grounded to ensure the safety of electrical equipment and personnel, prevent the outer shell from being electrified and endangering life, and at the same time protect the power system from hazards such as electric shock and lightning strike.

[0003] Chinese Patent Publication No. 218586374U discloses a grounding device for a distribution network, which relates to the technical field of distribution networks. It includes a fixed box. Inside the fixed box, a left support plate and a right support plate are fixedly arranged. A rotating shaft is arranged between the left support plate and the right support plate. The two ends of the rotating shaft are respectively rotatably connected to the left support plate and the right support plate. A wire is wound around the peripheral wall of the rotating shaft. The left end of the rotating shaft is connected to a connecting rod, and the other end of the connecting rod extends outside the fixed box and is rotatably connected to the side wall of the fixed box. One end of the connecting rod located outside the fixed box is fixedly connected to a driving device for driving the connecting rod to rotate. The lower end of the fixed box is fixedly provided with a storage box, and the storage box is communicated with the fixed box. An expansion cylinder is arranged inside the storage box. One end of the wire passes through the inside of the expansion cylinder and extends to the lower end of the expansion cylinder. One end of the wire located at the lower end of the expansion cylinder is detachably fixedly connected to a cross steel.

[0004] However, when this utility model is actually used, the following problems exist:

[0005] 1. The outer shell of this grounding device for a distribution network is relatively closed. When the internal wire is damaged, it is rather troublesome to repair the internal wire.

[0006] 2. For this grounding device for a distribution network, there is a lack of a fixing device at the connection between the expansion cylinder and the ground. Since the expansion cylinder is inserted into the ground, the soil around the expansion cylinder is relatively loose. After being eroded by wind and rain continuously, the device becomes unstable and easy to shake. Summary of the Utility Model

[0007] In order to overcome the above defects of the prior art, the utility model provides a grounding device for a distribution network, which solves the problems in the prior art:

[0008] 1. The shell of the grounding device of this distribution network is relatively enclosed. When the internal wires are damaged, it is rather troublesome to repair the internal wires.

[0009] 2. For this grounding device of the distribution network, there is a lack of a fixing device at the connection between the telescopic cylinder and the ground. Since the telescopic cylinder is inserted into the ground, the soil around the telescopic cylinder is relatively loose. After being eroded by wind and rain continuously, the device becomes unstable and prone to shaking.

[0010] To achieve the above purposes, the present utility model is realized through the following technical solutions: A grounding device for a distribution network, including a bottom plate. A protective box is fixedly installed on the top of the bottom plate, and a top cover is hingedly connected to the top of the protective box. Both sides of one end of the top cover are connected to a connecting rod through a spring bearing. A baffle is fixedly installed on one side of the connecting rod, and a first card slot is opened in the middle of the baffle. A clamping block is fixedly installed on one side of the protective box close to the baffle, and there are two groups of left and right clamping blocks. The clamping block is inserted into the first card slot. A round steel is inserted through the middle of the bottom plate, and a limiting ring is fixedly installed on the top of the round steel. A wiring terminal is fixedly installed on the top of the limiting ring, and a wire is connected to one side of the wiring terminal.

[0011] Optionally, a stabilizing ring is fixedly installed at the bottom of the bottom plate, and the stabilizing ring is communicated with the groove in the middle of the bottom plate. The round steel is inserted into the stabilizing ring. Pressure plates are arranged on both sides of the top of the limiting ring, and sliders are fixedly installed at both ends of the pressure plate. Sliding grooves are opened on the left and right inner walls of the protective box, and the sliders are embedded in the sliding grooves and are slidably connected with the sliding grooves.

[0012] Optionally, storage grooves are opened at the top of both sides of the protective box, and the wire is clamped inside the storage grooves.

[0013] Optionally, the length and width of the first card slot are the same as the length and width of the clamping block.

[0014] Optionally, the clamping block is arranged in a triangular prism shape, and a rubber gasket is pressed at the bottom of the clamping block.

[0015] Optionally, the diameter of the round steel is the same as the diameter of the groove in the middle of the bottom plate and the inner wall diameter of the stabilizing ring, and the diameter of the limiting ring is greater than the diameter of the round steel.

[0016] Optionally, the bottom surface of the limiting ring fits with the top of the bottom plate, and the top surface of the limiting ring fits with the bottom of the pressure plate.

[0017] Optionally, a second card slot is opened on one side of the pressure plate close to the wiring terminal, and the second card slot is mutually clamped with the wiring terminal.

[0018] The present utility model provides a grounding device for a distribution network, which has the following beneficial effects:

[0019] The grounding device of the distribution network is hinged with a top cover at the top of the protection box. Cooperating with the connecting rod and the baffle plate installed on both sides of one end of the top cover through spring bearings, when it is necessary to install or repair the round steel, just dial the baffle plate to one side so that the first card slot no longer engages with the card block, and then flip the top cover upwards to open it, and the round steel can be taken out. It not only plays a role in protecting the round steel and the wire, but also can very conveniently take out the round steel for maintenance.

[0020] The grounding device of the distribution network has the round steel embedded in the stabilizing ring. Cooperating with the two groups of pressing plates sliding horizontally in the protection box, after inserting the round steel to the bottom, the two groups of pressing plates can be both slid inwards so that the second card slot engages with both sides of the wiring terminal. At the same time, the limiting ring can be fixed between the bottom plate and the pressing plate. While fixing the round steel and the limiting ring, it is also beneficial to improve the stability of the round steel so that the round steel is not easy to shake. Brief Description of the Drawings
