Detailed Description
In an inflatable easy-folding rod as shown in fig. 1-3, the main body of the easy-folding rod is composed of an inflatable membrane tube column 100, and the inflatable membrane tube column 100 comprises a plurality of layers of airtight chambers which are hermetically separated from each other up and down but are connected into a whole. For example, the airtight chambers shown in fig. 1 include a top chamber 10, a middle first chamber 20, a middle second chamber 30, and a bottom chamber 40 from top to bottom, and there may be more or less middle chambers. The top of the inflatable membrane tubular column 100 is connected with the inflatable membrane tubular beam 2, and the bottom is connected with the mounting base 9. And the corresponding airtight chamber of each layer is matched with an inflation and deflation pipeline, an electromagnetic valve and a pressure sensor. The pressure sensors are respectively arranged near the mouths of the inflation and deflation pipelines in the inflation film pipe column or in the inflation and deflation pipelines, each inflation and deflation pipeline is connected with the inflation and deflation main pipeline 8 at the bottom, and the inflation and deflation main pipeline 8 is connected with the intelligent monitoring and pressurizing device 7. The intelligent monitoring and pressurizing device 7 is used for monitoring the air pressure of each layer of airtight chamber and independently inflating one or more layers of airtight chambers when needed.
Each airtight chamber and inflation and deflation conduit are specifically: the upper and lower tubular beam inflation and deflation pipelines 12 are connected into the uppermost inflatable membrane tubular beam 2, the upper inflation and deflation pipeline 3 is connected to the lower part of the upper chamber 10, the middle first inflation and deflation pipeline 4 is connected to the lower part of the middle first chamber 20, the middle second inflation and deflation pipeline 5 is connected to the lower part of the middle second chamber 30, and the bottom inflation and deflation pipeline 6 is connected to the lower part of the bottom chamber 40. The intelligent monitoring and pressurizing device 7 can timely supplement gas if the gas pressure is reduced in normal use by monitoring the gas pressure of each airtight chamber. When the device is installed, the inflatable membrane tubular columns 100 and the inflatable membrane tubular beams 2 are inflated to form the structure of the conventional easy-to-fold rod for the upper airport. A navigation aid 10 such as a searchlight may be mounted on the inflatable membrane tube beam 2. The navigation aid 10 is connected with a power supply through a cable laying pipe 11 attached to the outer surface of the inflatable membrane pipe column 100. The cable laying pipe 11 is a hose, and is fixed outside the inflatable membrane column 100 by bonding or rope sleeve. The intelligent monitoring and inflating equipment 7 intelligently judges according to the parameters monitored by the sensors and timely adjusts the air pressure in real time. The mounting base 9 is used to secure the whole apparatus and a ring of blades 91 are arranged along the vicinity of the outer periphery of the inflatable membrane column 100 for cutting off the root of the inflatable membrane column 100 in a special case.
The inflatable membrane tubular column 100 and the inflatable membrane tubular beam 2 of the present invention are both made of a soft, high-strength membrane material, such as Polytetrafluoroethylene (PTEF) material. The PTEF membrane material is made into a closed hollow tubular structure, the inside and the outside of a hollow inner cavity of the PTEF membrane material generate pressure difference under certain air pressure, an inflatable membrane tube column 100 supported by air pressure and having structural strength is formed, and top equipment of the easy-to-fold rod is supported. And the carbon fiber yarns which are orderly woven are integrally processed in the polytetrafluoroethylene film material, so that the strength is improved, higher air pressure can be borne, and the high air pressure enables the easy-to-break rod to obtain higher rigidity and strength. The easy-to-break rod formed by the inflatable membrane tubular column 100 is light in weight, internal air pressure is rapidly reduced when the outer surface is damaged, structural strength is rapidly lost, impact on an airplane is extremely small when an airplane collision accident happens, and the easy-to-break rod is superior to other easy-to-break rods made of other materials in the market. The product can be reliably broken under special working conditions, and has low cost, and the product of the invention is easier to adopt in a higher structure. When the maintenance of the navigation aid equipment is needed, the height of the navigation aid equipment can be reduced to the ground only by gradually deflating, so that the maintenance of the navigation aid equipment is convenient.
The working principle of the invention is similar to that of an inflatable castle for children to play with, and the inflatable castle has enough structural strength to support navigation aid equipment. However, the invention adopts polytetrafluoroethylene materials and the like which have better strength, corrosion resistance and weather resistance. The core of the inflatable membrane structure is that the membrane material is filled according to the designed appearance through high-strength air pressure formed by inflation, so that corresponding rigidity and strength are formed, and the rigidity and strength are closely related to the internal air pressure.
The pressure monitoring and pressurization are mainly monitored by the intelligent monitoring and inflating device 7 and the pressure sensor near the inside of the inflation and deflation pipeline or the outside of the pipe orifice. When the pressure in the pipe is less than the preset lower limit value, the intelligent monitoring and inflating device 7 pressurizes the main inflating and deflating pipe 8, opens the electromagnetic valves on the corresponding branch inflating pipes, and pressurizes the corresponding airtight chambers until the pressure in the pipe or the airtight chambers (the two air pressures should be balanced, so that the pressure can be detected in the pipe or the airtight chambers) reaches the upper limit value of the pressure. Preferably, the intelligent monitoring and inflating equipment 7, the sensor and the electromagnetic valve are two sets, one set is main and the other set is standby, when one set of device breaks down, the standby device can be automatically started, and an alarm maintenance signal is sent out. The main inflation and deflation pipeline 8 and the downstream of the electromagnetic valve in the inflation direction are provided with rapid pressure relief valves, when the intelligent monitoring and inflation equipment 7 detects that the pressure of a certain chamber is increased, the internal air pressure is increased due to the fact that the aircraft collides with the inflation membrane pipe column 100 possibly; when the intelligent monitoring and inflating device 7 monitors the change, the quick pressure relief valve is started to quickly relieve the pressure of the inflatable membrane column 100.
More preferably, as shown in FIG. 2, the inflatable membrane column 100 is formed by coaxially gathering a plurality of inflatable membrane tubes. I.e. the gas-filled membrane column 10 comprises several separate tubular bodies in the same cross-section. Each tube body is a tapered tube with a large lower end and a lower upper end, and is coaxially arranged along the axis of the formed inflatable membrane tube column 100. The illustrated inflatable membrane column 100 includes a central tube 102 and 6 peripheral tubes 101, each having a regular hexagonal cross-section that closely surround the central tube 100. The pipe bodies can share the pipe wall structure, and the shared pipe wall can ensure the strength because of consistent air pressure, and can save materials. Or the independent pipe walls are bonded with each other, and an inflation pipeline is conveniently arranged in a bonding seam between two or three pipe bodies. For example, as shown in fig. 2, a cable laying pipe 11 is disposed in a concave portion between two outer pipe bodies of the high-rise chamber 10, and a tubular beam inflation/deflation pipe 12 is disposed between three inner pipe bodies. The high-rise air inflation and deflation pipeline 3 of the high-rise chamber 10 is communicated from the space between the two lower pipe bodies, then is distributed into each peripheral pipe body 101 through the opening on the annular circular pipe 32, and is distributed into the middle pipe body 102 through a radial pipe 31. The corresponding pressure sensor is arranged in the high-rise inflation and deflation pipeline 3. The cross section of each pipe body can also be circular; or as shown in fig. 4, the outer sides of the two sides are regular hexagonal contour lines and circular contour lines; not only can be matched with each other tightly, but also has the appearance of smoothness and better wind resistance.
As shown in fig. 3, the inside of each of the tubes 101 and 102 is divided into a plurality of layers by the transverse diaphragms 21, and the air holes 22 are provided in the middle of each layer of the diaphragms 21. Therefore, the structural strength of the pipe bodies 101 and 102 can be enhanced, and each layer of the inflation and deflation pipe column 10 can be gradually hardened from bottom to top during inflation, so that the lifting and maintenance of the equipment are facilitated.
The invention is also simple to use and install: the height of the easy-to-break rod is determined according to airport design requirements, and the air pressure requirement of the inflatable membrane is determined through stress analysis design, so that the inflatable membrane tubular column 100 and the inflatable membrane tubular beam 2 are determined; then the intelligent monitoring and pressurizing device 7 inflates air through an air inflation and deflation pipeline until the required air pressure is reached; before inflation, the navigation aid 10 and the cable laying pipe 11 are installed and wired on the ground.
The key point of the inflation process is 'orderly pressurization', the whole height is divided into 4 sections (the number is variable), and the inflation membrane tubular beams 2 are firstly completed during inflation; the bottom layer cavity is completed through the bottom layer inflation and deflation pipeline 6, the middle second cavity 30 positioned at the lower side of the middle part is completed through the middle second inflation and deflation pipeline 5, and the middle first cavity 20 is gradually inflated upwards until the inflation of the high-rise cavity 10 is completed through the high-rise inflation and deflation pipeline 3; after all the inflation is finished, the internal air pressure is monitored in real time and adjusted in real time through the intelligent monitoring and pressurizing device 7.
When the navigation aid equipment needs to be overhauled, the navigation aid equipment can be realized by adopting 'ordered pressure relief', namely the pressure relief is carried out by the intelligent monitoring and pressurizing equipment 7 according to the sequence opposite to the inflation, the pressure relief is carried out by sequentially passing through the high-rise inflation and deflation pipeline 3 to relieve the pressure of the high-rise cavity 10, and then sequentially completing the middle first cavity 20 positioned at the upper side and the middle second cavity 30 positioned at the lower side by passing through the middle first inflation and deflation pipelines 4 and 5 until the deflation of the bottom cavity 40 is completed by passing through the bottom inflation and deflation pipeline 6, and the top navigation aid equipment is landed; after the maintenance is finished, the air inflation process is repeated, and the navigation aid equipment can be lifted to the top.
