Description

Technical Field

[0001] The invention relates to the technical field of spraying and liquid recovery, and in particular to a recovery device for a sprayed hydrophobic agent of a high-speed railway transmission contact network. Background Art

[0002] With the rapid development of high-speed rail networks, higher requirements have been placed on the reliability and safety of transmission contact networks, especially in severe weather conditions in winter, when it becomes particularly important to ensure the normal operation of trains. At present, the high-speed rail industry at home and abroad has conducted certain research and practice on the protection technology of transmission contact networks, but there are still many shortcomings. For example, traditional anti-icing measures mainly rely on heating equipment and mechanical removal methods, which have limited effects in extreme weather and consume a lot of manpower and material resources during implementation.

[0003] The main defects of the prior art include:

[0004] High labor costs: Existing manual spraying or cleaning methods require a lot of labor, resulting in high labor costs.

[0005] Low efficiency: Traditional spraying methods are difficult to cover long distances of transmission overhead lines, especially in bad weather conditions, which significantly reduces the efficiency of the operation.

[0006] Difficulty in recycling: Traditional spraying methods cannot effectively recycle the sprayed liquid, resulting in a large amount of waste of hydrophobic agent that cannot be sprayed into the transmission contact network area. This not only increases the economic burden, but the unabsorbed materials also cause pollution to the soil and water sources.

[0007] Possible reasons include the lag of technical means, the inadaptability of equipment and materials, and the lack of targeted solutions. Therefore, the applicant hopes to seek a new technical solution to realize the recycling of the hydrophobic agent sprayed on the high-speed railway transmission contact network. Summary of the invention

[0008] In view of this, the purpose of the present invention is to provide a method for testing the application stability of an effect powder coating composition during electrostatic spraying, which can achieve good detection of the application stability of the effect powder coating composition during electrostatic spraying, and the testing process is simple and fast and the testing cost is low, which is very suitable for application in the production of the effect powder coating composition or the subsequent spraying recovery process.

[0009] The purpose of the present invention is to provide a recovery device suitable for high-speed railway power transmission contact network hydrophobic agent spraying, which is used to overcome the problem of high spraying cost and environmental pollution caused by the sprayed hydrophobic agent being unable to be recovered, and the collected hydrophobic agent can be used for secondary use after being processed.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A recovery device suitable for spraying a hydrophobic agent on a high-speed railway transmission contact network, comprising:

[0012] The collection and spraying assembly comprises: a first baffle, a second baffle, a first spray gun, a second spray gun, and a collection tank, wherein the first baffle and the second baffle are respectively fixed on both sides of the device to form a collection area for guiding the unattached hydrophobic agent during the spraying process to flow into the collection tank. The two baffles are arranged at an angle so that the liquid slides into the collection tank along the baffles. The first spray gun and the second spray gun are symmetrically installed in the middle and upper part of the baffle and fixed on the transverse support structure. The spraying angle of the spray gun can be adjusted by the spray gun to ensure that the hydrophobic agent is evenly covered on the high-speed rail transmission contact network. The collection tank is located at the bottom of the first baffle and the second baffle, and is fixedly connected to the baffle through a slideway to receive the hydrophobic agent guided downward by the baffle. The collection tank is a funnel-shaped structure design with a round sky and a square square, with a circular opening at the bottom and a square collection port at the top, forming a tapered shape with a wide top and a narrow bottom, so that the unattached hydrophobic agent during the spraying process automatically flows downward by gravity.

[0013] The transmission and recovery component includes: a recovery pipe and a liquid storage tank. One end of the recovery pipe is connected to the drain port at the bottom of the collection tank, and the other end is connected to the inlet of the liquid storage tank, so as to transport the collected hydrophobic agent to the liquid storage tank. The liquid storage tank is used to store the recovered hydrophobic agent. The liquid storage tank is equipped with a liquid outlet and is connected to the spray liquid supply tank through another pipe, so as to realize the recycling of materials.

[0014] The support and fixing assembly includes: a four-corner stabilizing frame, a connecting rod, and a base. The four-corner stabilizing frame fixes the baffles on both sides. The four-corner stabilizing frame is equipped with a connecting rod, which is connected to the base through the connecting rod to play the role of fixing the support collection and spraying assembly. The base is equipped with a mounting hole and can be fixed on the top of the train.

[0015] Preferably, the spray gun can adopt a multi-angle adjustable structure so as to adjust the spraying angle according to different positions and shapes of the transmission contact network, thereby ensuring that the hydrophobic agent can be evenly sprayed on the surface of the contact network and improving the spraying effect.

[0016] Preferably, the baffle material may be made of alloy material or engineering plastic with strong wear resistance to extend the service life of the collection structure and reduce equipment maintenance costs.

[0017] Preferably, the collecting port of the recovery device can be designed as a wide-mouth funnel, which can more effectively receive the refluxed liquid, reduce splashing, and ensure that more hydrophobic agent is recovered into the liquid storage tank.

[0018] As a preference, the support and fixing assembly may be made of high-strength alloy material to ensure its stability and durability when subjected to heavy loads. This material selection can reduce structural damage caused by material fatigue, thereby extending the service life of the entire device.

[0019] Preferably, the surface of the base may be treated to be anti-slip, such as by adding texture or coating, to increase the friction between the base and the ground, thereby preventing sliding during use and ensuring the safety of the device.

[0020] Preferably, the liquid storage tank can be designed as a detachable structure to make cleaning and maintenance more convenient, which helps to extend the service life of the equipment.

[0021] In the above technical solution, the present invention provides a recovery device suitable for spraying hydrophobic agent on high-speed railway transmission contact network, which has the following beneficial effects:

[0022] 1. The invention is equipped with a high-intensity spray gun, which can achieve uniform spraying of the hydrophobic agent and cover the entire surface of the transmission contact network. At the same time, the collection device can effectively recover the unattached hydrophobic agent to avoid waste. This design greatly reduces material loss, operating costs and resource waste.

[0023] 2. A storage tank is configured to store the recycled hydrophobic agent, which is used for spraying again after secondary treatment, forming a recycling system. This design not only reduces the consumption of hydrophobic agent, but also reduces environmental pollution caused by material volatilization or leakage, which helps to achieve both environmental protection and economic benefits.

[0024] 3. With the integrated design of the spray gun and the baffle, combined with the movable base, its position can be adjusted according to different contact network heights, and it has strong adaptability. The device can flexibly adjust the spraying position to meet the needs of the operation, making it suitable for complex on-site environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The two spray guns are respectively fixed at the middle position of the upper part of the two baffles. Due to the double-sided spraying, the spraying range is fan-shaped, which is perpendicular to the transmission contact network to form a complete coverage area.

[0036] The first baffle plate 2 and the second baffle plate 3 are respectively designed with a slideway 12 , and the hydrophobic agent not attached to the contact network 1 follows the slideway 12 on the inner side of the baffle plate under the action of gravity and finally falls into the collecting tank 6 .

Step 5 If it is necessary to perform performance testing on the sprayed product, open the liquid storage tank 8, take out a small amount of the hydrophobic agent in the liquid storage tank as a sample, and test its waterproof performance.

[0040] The present invention proposes a recovery device suitable for spraying hydrophobic agent on high-speed railway power transmission contact network in view of the key technical measures for anti-icing of high-speed railway power transmission contact network, aiming to spray hydrophobic agent on transmission line to improve its wear resistance and corrosion resistance while collecting the hydrophobic agent that fails to be adsorbed on the contact network.
