Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of rainproof for pipeline mouth, and particularly relates to a gas cover type rainproof and pollution prevention device for pipeline mouth. BACKGROUND

[0002] In today's rapid development of high-tech, with the advent and rapid development of material science, power electronic devices and high-performance integrated circuits, mankind has made numerous attempts in launching technology using various energies. Based on electromagnetic launching technology, the application and development of electromagnetic energy equipment are constantly improving with the test mechanism, but there are still two problems to be solved. On the one hand, during the test process, due to the influence of external airflow, some impurities or objects affecting the insulation performance may be blown off to the pipeline mouth, thereby degrading the internal environment of the pipeline mouth and affecting the stability and accuracy of the test. On the other hand, a certain amount of test activities still need to be carried out in the rainy environment, and the falling of rainwater will further deteriorate the insulation environment of the pipeline mouth and its interior, thereby reducing the parameters such as surface flashover voltage and surface resistivity of the pipeline mouth and its interior, and reducing the service life of the insulation support in the pipeline.

[0003] The current technology uses a rain cloth to shield the pipeline mouth in a rainy environment, which can shield the pipeline mouth and cover the entire pipeline at the same time, but the rain cloth hinders the further test of electromagnetic energy equipment, which has an adverse effect. In order to solve this problem and enable normal testing in a rainy environment, a pipeline mouth gas cover type rainproof and pollution prevention device is needed to maintain and protect the excellent use environment of the pipeline mouth and the interior of the pipeline. SUMMARY

[0004] The purpose of the present application is to solve the problem that a large number of tests can be carried out in the current rainy and more polluted external environment, and to propose a gas cover type rainproof and pollution prevention device for pipeline mouth.

[0005] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: a gas cover type rainproof and pollution prevention device for pipeline mouth, comprising a pipeline, a fixed ring, a damping shock-absorbing spring, a connecting shaft and a high-pressure jet air nozzle.

[0006] The pipeline is of a square structure.

[0007] The fixed ring is connected to the outer periphery of the pipeline through the damping shock-absorbing spring, one end of the damping shock-absorbing spring is welded to the outer wall of the pipeline, and the other end is fixedly welded to the corresponding position on the inner side of the fixed ring. A plurality of damping shock-absorbing springs are uniformly arranged on the inner side of the fixed ring along the circumference of the fixed ring. The damping shock-absorbing spring is used for the position of the fixed ring. A plurality of axially protruding supports are uniformly arranged on the outer side of the fixed ring along the circumferential direction.

[0008] The connecting rotating shaft is used for connecting the support of the fixed circular ring and the high-pressure jet gas nozzle, so that the high-pressure jet gas nozzle can dynamically adjust the pitch angle and the rotating angle of the high-pressure jet gas nozzle according to the change of the external environment, thereby forming an airflow type adjustable four-pyramid gas cover; when the high-pressure jet gas nozzle is connected with high-pressure gas, the gas flows into the high-pressure jet gas nozzle through the cylindrical conduit, and the cylindrical gas is converted into rectangular surface gas through the high-pressure jet gas nozzle, so as to increase the cross section of the airflow to form a dense gas cover.

[0009] As a further description of the above technical solution: the damping shock spring is provided as 4, and the support is also provided as 4.

[0010] As a further description of the above technical solution: the damping shock spring is made of corrosion-resistant and high-elastic spring steel, and the structure includes a spiral spring or a compression spring.

[0011] As a further description of the above technical solution: the fixed circular ring is selected from high-strength and high-temperature-resistant titanium alloy materials; in terms of structure, the inner side of the fixed circular ring is designed to be integrally fitted with the pipeline.

[0012] As a further description of the above technical solution: the high-pressure jet nozzle is equipped with a gas valve for adjusting the pressure and direction of the jet airflow; the nozzle is made of alloy materials that are resistant to corrosion and deformation under high pressure.

[0013] The pipeline can be reasonably set according to its own needs to be applied to the launch test of electromagnetic energy equipment under different energy; the safety fixed circular ring must consider the safety distance and a certain safety margin, and when the electromagnetic energy equipment launch test is carried out, instantaneous high temperature, strong shock wave and other extreme electromagnetic environments will be generated, at this time, the circular ring structure will not be damaged, thereby playing a role in fixing and supporting other equipment; the primary role of the damping shock spring is to fix the position of the circular ring, and the secondary role is that the damping shock spring can effectively reduce the vibration and impact of the external environment on the circular ring and its attached structure, and protect the device components from damage; the connecting rotating shaft is used for connecting the circular ring support and the high-pressure jet gas nozzle, and can also dynamically adjust the included angle between the circular ring support and the high-pressure jet gas nozzle according to the natural environment, thereby forming an airflow type adjustable four-pyramid gas cover; when the high-pressure jet gas nozzle is connected with high-pressure gas, the gas flows into the high-pressure jet gas nozzle through the cylindrical conduit, and the cylindrical gas is converted into rectangular surface gas through the gas nozzle, mainly to increase the cross section of the airflow to form a dense gas cover.

[0014] As a further description of the above technical solution:

[0015] The distance between the ring and the pipe opening should fully consider the safety distance under extreme electromagnetic environment. The outer diameter of the ring should be greater than the safety distance, and the scanning diameter should be as small as possible to avoid the problem of a sharp increase in the stress on the pipe wall due to the increase in gravity at the pipe opening.

[0016] As a further description of the above technical solution:

[0017] The installation of the damping spring should take into account the distance between the pipe corner and the inner ring, and the two are tightly connected by the spring and the welding hole.

[0018] As a further description of the above technical solution:

[0019] The selection of the material and damping ratio of the damping spring should fully consider the energy and vibration brought to the device by the shock wave generated during the electromagnetic energy equipment test.

[0020] As a further description of the above technical solution:

[0021] In the high-pressure jet nozzle, the cylindrical pipe and the nozzle head are tightly connected by threads, and the stress-strain resistance between them is greater than that generated by the high-pressure jet gas. The powerful airflow pressure can directly cause a phase change in raindrops, thus preventing rainwater from falling into the pipe.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] In this invention, the main protective mechanism of the pipeline inlet air hood type rainproof and anti-fouling test device mainly includes four modules: a fixed ring, a damping spring, a connecting shaft, and a high-pressure jet nozzle. The ring is used to fix the position of the connecting shaft, and the angle of the high-pressure jet nozzle is fixed and dynamically adjusted on the shaft. High-pressure gas is supplied to the high-pressure nozzle through a cylindrical pipe at the pipeline end and ejected from the high-pressure nozzle. The damping spring is used to resist the vibration of the device caused by the shock wave, thereby forming a stable four-sided pyramid air hood, achieving a rainproof and anti-fouling effect. This significantly improves the environment of the pipeline inlet under harsh natural conditions such as rain, increases the service life of the insulating components in the pipeline, and promotes the development of electromagnetic energy equipment.

The embodiments are based on the technical solutions of the present application and give specific implementation and operation processes, but the protection scope of the present application is not limited to the following embodiments.

[0030] The present application provides a gas cover type rain and pollution prevention device for a pipeline port, which comprises a pipeline 1, a fixed ring 2, a damping shock-absorbing spring, a connecting shaft and a high-pressure jet gas nozzle 3.

[0031] The pipeline 1 can be reasonably set in caliber according to its own needs, so as to be applied to the launch test of electromagnetic energy equipment under different energy; the fixed ring 2 must consider the safety distance and be provided with a certain safety margin, and extreme electromagnetic environments such as instantaneous high temperature and strong shock wave will be generated during the launch test of electromagnetic energy equipment, at this time, the fixed ring 2 structure will not be damaged, thereby playing a role in fixing and supporting other devices; the primary role of the damping shock-absorbing spring is to fix the position of the fixed ring 2, and the secondary role is that the damping shock-absorbing spring can effectively reduce the vibration and impact of the external environment on the ring and its attached structure, thereby protecting the device components from damage; the connecting shaft is used to connect the ring support and the high-pressure jet gas nozzle 3, and can also dynamically adjust the included angle between the ring support and the high-pressure jet gas nozzle 3 according to the natural environment, so as to form an airflow type adjustable four-pyramid gas cover; when the high-pressure jet gas nozzle 3 is connected to high-pressure gas, the gas flows into the high-pressure jet gas nozzle 3 through the cylindrical conduit, and the cylindrical gas is converted into rectangular gas through the gas nozzle, mainly to increase the cross section of the airflow to form a dense gas cover.

[0032] Embodiment 1

[0033] As shown in Figures 1-5 , Figure 1 , the pipeline 1 in the fixed ring 2 is made of metal material with corrosion resistance and strong pressure resistance, and stainless steel or alloy steel is usually selected, and the shape and caliber of the pipeline can be set to different calibers according to needs. Figure 3 In order to ensure that the device can work stably under the vibration and impact of the external environment, the damping shock-absorbing spring is usually made of corrosion-resistant and high-elasticity spring steel in terms of material and structure, and its structure includes a spiral spring or a compression spring to provide sufficient elastic support. In terms of connection, one end of the damping shock-absorbing spring is connected to the inner ring of the fixed ring 2, and the other end is connected to the pipeline wall, so as to ensure the stability of the entire device. Figure 3The fixed ring 2 is usually made of titanium alloy material with high strength and high temperature resistance to ensure that it will not deform or be damaged in extreme electromagnetic environment. In terms of structure, the inner side of the fixed ring 2 is designed to be in close contact with the shape of the pipeline as a whole to ensure that it is firmly fixed around the pipeline opening. The outer side can be designed to be flat or convex to provide sufficient support area. The connecting shaft is used to connect the fixed ring 2 with the high-pressure jet nozzle 3 and can dynamically adjust the pitch angle and rotation angle of the high-pressure jet nozzle 3 according to the changes of external environment; in terms of material and shape, the connecting shaft is usually made of strong and durable metal material, and the shape is cylindrical with connecting holes at both ends to ensure stability through threaded connection or pin connection. Figure 5 The high-pressure jet nozzle 3 is the key component of the present application, which has a structure with high-pressure jetting capability to form a protective gas cover to prevent rain and pollutants from entering the pipeline opening. In terms of jetting force control, the nozzle is usually equipped with a gas valve or other control device to adjust the pressure and direction of the jet gas flow to adapt to different degrees of external test environment. The nozzle material is usually made of alloy material that is resistant to corrosion and not easy to deform under high pressure. The gas outlet of the nozzle is a long strip-shaped nozzle.

[0034] During the above operation, the working state of the device is monitored regularly to ensure that the high-pressure jet nozzle 3 can normally jet and effectively protect the pipeline opening and its internal environment. If stable gas flow cannot be obtained, it is difficult to form a constant gas cover, and thus the rain and pollution prevention effect cannot be achieved.

[0035] During the above operation, the connection state of each component is checked regularly to ensure that the fixed ring 2, damping shock spring, connecting shaft and other components are not loose or damaged.

[0036] During the above operation, the connecting shaft and the high-pressure jet nozzle 3 can be increased or decreased on the fixed ring 2 to dynamically adjust to form different three-dimensional shapes of the gas cover, such as triangular pyramid, quadrangular pyramid or even cylinder, to achieve the effect of rain and pollution prevention.

[0037] After the above operation is completed, the electromagnetic energy equipment is turned off, and the high-pressure jet nozzle 3 can be turned off or turned on according to the needs.

[0038] The present application breaks through the existing rain cloth type rain cover form and provides technical support for a large number of tests in a rainy and polluted external environment, and is widely used, convenient and flexible, and low in cost.

[0039] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change within the technical scope disclosed by the present application and according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
