Description

Technical Field

[0001] The utility model relates to the technical field of distribution network operation detection, in particular to a power system distribution network operation detection device. Background Art

[0002] A distribution network refers to an electric power network that receives electric energy from a transmission network or a regional power plant and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid.

[0003] In the prior art, when a detection device is used to detect the operation of a distribution network, the detection equipment is heavy and requires workers to hold the detection equipment, which makes the detection work difficult for the workers and also reduces the safety of the workers. Utility Model Content

[0004] The purpose of the present utility model is to solve the following shortcomings in the prior art: when the detection device in the prior art detects the operation of the distribution network, the detection equipment is heavy and requires the staff to hold the detection equipment, which will bring difficulty to the staff's detection work and also reduce the safety of the staff. A power system distribution network operation detection device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A power system distribution network operation detection device comprises a detection device body and a fixing block, wherein the fixing block is fixedly connected to one end of the detection device body;

[0007] An adsorption component is installed at one end of the detection device body, and the adsorption component includes an air collecting chamber, a suction cup, a square cavity, a piston plate, and a connecting pipe. The air collecting chamber is fixedly connected to the side wall of the detection device body, and the two suction cups are connected to the air collecting chamber. The two square cavities are respectively fixedly connected to the two ends of the detection device body. The lower end of the piston plate is slidably connected in the square cavity. The connecting pipes are respectively fixedly connected between the square cavity and the air collecting chamber. A spring is fixedly connected between the lower end of the piston plate and the bottom wall of the square cavity.

[0008] Preferably, the adsorption component further includes a rotating shaft, a cam, and a limit plate. The rotating shaft passes through the air collecting chamber, the two cams are fixedly connected to both ends of the rotating shaft, and the two limit plates are fixedly connected to the upper end of the piston plate.

[0009] Preferably, both ends of the fixed block are slidably connected to movable blocks, and the movable blocks are arranged in a right-angled trapezoid.

[0010] Preferably, a transverse plate is fixedly connected to the moving block, and an end of the transverse plate away from the moving block is fixedly connected to an arc-shaped plate.

[0011] Preferably, the upper ends of the two piston plates are respectively slidably connected to the inclined surfaces of the moving block.

[0012] Preferably, one end of the detection device body is fixedly connected to a protrusion, and the protrusion is located at the lower side of the gas collecting cavity.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Since the lower end of the piston plate slides in the square cavity in a sealed manner, the square cavity can be in a negative pressure state when the piston plate moves up. Since the square cavity is connected with the square cavity through the connecting pipe, the suction cup can be more stably adsorbed on the outer surface of the pole of the distribution network, thereby fixing the detection device body.

[0015] 2. When the detection device body approaches the power grid pole, the power grid pole is located between the two curved plates. Therefore, when the two curved plates move with the moving block through the cross plate, they can clamp and fix the power grid pole, and cooperate with the suction cup to better fix the power grid pole.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0022] Reference Figure 1-Figure 3 A power system distribution network operation detection device includes a detection device body 1 and a fixed block 12, the fixed block 12 is fixedly connected to one end of the detection device body 1, and the two ends of the fixed block 12 are respectively slidably connected to the moving block 2, the moving block 2 is arranged in a right-angled trapezoid, a horizontal plate 3 is fixedly connected to the moving block 2, and the end of the horizontal plate 3 away from the moving block 2 is fixedly connected to the arc plate 4, and one end of the detection device body 1 is fixedly connected to a protrusion 10, the protrusion 10 is located on the lower side of the gas collecting cavity 6, and the protrusion 10 has a certain thickness, which is used to keep the detection device body 1 in a vertical state when it is attached to the distribution network pole.

[0023] One end of the detection device body 1 is equipped with an adsorption component, which includes a gas collecting chamber 6, a suction cup 5, a square chamber 9, a piston plate 11, and a connecting pipe 8. The gas collecting chamber 6 is fixedly connected to the side wall of the detection device body 1. The two suction cups 5 are connected to the gas collecting chamber 6. The two suction cups 5 are arranged up and down. The two square chambers 9 are fixedly connected to the two ends of the detection device body 1. The lower end of the piston plate 11 is slidably connected to the square chamber 9. The outer surface of the lower end of the piston plate 11 is sealed and slidably connected to the inner wall of the square chamber 9. The upper ends of the two piston plates 11 are respectively connected to the movable The inclined surface of block 2 is slidably connected, and the connecting pipe 8 is fixedly connected between the square cavity 9 and the gas collecting cavity 6. A spring 16 is fixedly connected between the lower end of the piston plate 11 and the bottom wall of the square cavity 9. The spring 16 always has an upward pushing force on the piston plate 11. The adsorption component also includes a rotating shaft 15, a cam 10, and a limit plate 14. The rotating shaft 15 passes through the gas collecting cavity 6. The rotating shaft 15 is sealed and slidably connected to the side walls at both ends of the gas collecting cavity 6. The two cams 13 are fixedly connected to the two ends of the rotating shaft 15, and the two limit plates 14 are fixedly connected to the upper end of the piston plate 11.

[0024] In the present utility model, first, the distribution network operation detection device body 1 is placed on one side of the pole of the distribution network, the detection device body 1 is pushed to move toward the pole of the distribution network, and the suction cup 5 is fitted with the outer surface of the pole of the distribution network. The swing plate 7 is squeezed by the pole of the distribution network to drive the rotating shaft 15 to rotate. When the cam 13 rotates with the rotating shaft 15, it can push the limit plate 14 and the piston plate 11 to move upward. Since the lower end of the piston plate 11 is sealed and slides in the square cavity 9, the square cavity 9 can be in a negative pressure state when the piston plate 11 moves upward. Since the square cavity 9 is connected to the square cavity 9 through the connecting pipe 8, the suction cup 5 can be more stably adsorbed on the outer surface of the pole of the distribution network, thereby achieving the fixing effect on the detection device body 1.

[0025] At the same time, as the piston plate 11 moves upward, the two moving blocks 2 can be pushed to move the rod in the center. When the detection device body 1 approaches the grid pole, the grid pole is located between the two curved plates 4. Therefore, when the two curved plates 4 move with the moving block 2 through the cross plate 3, the grid pole can be clamped and fixed.
