guano propulsion device

Abstract

The invention discloses a bird dung propelling device, which comprises a bird dung container and a sealing container, wherein a cavity is formed inside the bird dung container, a feeding device is arranged on the bird dung container, the feeding device is communicated with the cavity through a second valve, the lower end of the bird dung container is provided with a discharging opening communicated with the cavity, the discharging opening is provided with a spray nozzle, the outlet of the spray nozzle is provided with a blocking and plugging device, a one-way valve is arranged on the sealing container, and the cavity of the bird dung container is communicated with the sealing container through a communication pipe provided with a first valve. The bird dung propelling device has the advantages that the bird dung container is adopted for containing bird dung simulation liquid, the sealing container is used for storing compressed air, and in addition, the compressed air entering the bird dung container is used for spraying out the bird dung simulation liquid from a spray opening, so the experiment simulation of forming a bird dung passage between a cross beam and a conducting wire during bird defecation on the cross beam is realized.

Description

technical field [0001] The invention relates to an auxiliary device for the safe operation of an overhead power transmission line, in particular to a bird droppings propulsion device for detecting discharge characteristics of crossarm-conductor gaps under the influence of bird droppings. Background technique [0002] With the mass reproduction of birds, the prevalence and harm of bird accidents have become increasingly prominent, and the line faults caused by them have become one of the main reasons for tripping accidents in power systems, seriously threatening the safe operation of power systems. According to a large number of observations and statistical data, there are mainly four types of bird damage faults on overhead transmission lines: ① When the bird spreads its wings and flies, the body short-circuits the air gap and causes a short-circuit fault; Fault; ③ bird feces pollute the surface of the insulator, resulting in its flashover fault along the surface in humid air...

Problems solved by technology

For example, the patent "A device for measuring the discharge characteristics of the air gap under the influence of bird droppings" with the application number of 201220194583.2 discloses a device for measuring bird droppings mainly composed of a voltage regulator, a transformer, a protection resistor, a voltage divider, and a bird droppings adjustment component. The device with air gap discharge characteristics under the influence of feces, in which the guano adjustment part adopts a simple funnel and a support frame, has the following disadvantages: ①The adjustment of the diameter of the falling guano must be realized by replacing the funnel, which is troublesome to operate and the utilization rate of the equipment is not high ; ②This device cannot simulate the compression of the bird's internal organs when the bird defecates, so the bird droppings cannot be discharged at a certain initial speed, which is inconsistent with the actual situation; ③The addition of bird droppings must be artificially added to the funnel before applying voltage , the workload is heavy and the safety of personnel cannot be guaranteed; ④ There is no switchgear, and the bird droppings simulation liquid is in a state of continuous circulation, which is easy to cause waste

[0004] Another example is the patent "A device for detecting the discharge characteristics of the tower window-conductor gap under the influence of bird droppings" with the application number of 201220386960.2, which discloses a device for detecting the discharge characteristics of the tower window-conductor gap under the influence of bird droppings. The bird droppings adjustment component is composed of a nozzle, a water pipe, an air compressor, a pneumatic diaphragm pump and a container containing bird droppings simulation liquid. The bird droppings are discharged through the pressure of the pneumatic pump. This device has the following disadvantages: ① Air compressor and pneumatic Diaphragm pumps are large in size, take up a lot of space, and are expensive; ②The length of the water pipe is long, and a large amount of guano simulated liquid will adhere to the pipe wall when it passes through, so it is impossible to accurately know the actual capacity of guano simulated liquid sprayed ;③The device is bulky and difficult to clean
