Description

Technical Field

[0001] The invention belongs to the technical field of antennas, and in particular relates to an external rubber stick antenna. Background Art

[0002] The external rubber stick antenna is a common type of antenna, mainly composed of the antenna body, rubber sleeve and interface part. The rubber stick antenna can receive and send radio wave signals and is suitable for mobile phones, wireless network equipment, car navigation systems and other electronic devices. The rubber stick antenna is small in size and easy for users to carry and install.

[0003] Rubber stick antennas are used in some special scenarios. For example, IoT devices in underground wells need to use rubber stick antennas to exchange data with ground monitoring systems, management platforms or other related equipment.

[0004] The environmental conditions inside underground wells often show the characteristics of high humidity, especially when the rainy season comes, or in those specific areas close to the groundwater level. This high humidity environmental condition will have a very significant impact on the rubber sleeve covering the surface of the rubber stick antenna. Specifically, the high humidity environment will greatly accelerate the aging process of the rubber sleeve, causing the surface of the rubber sleeve to gradually appear different degrees of damage. However, in actual use scenarios, it is usually difficult for operators to detect the damage of the rubber sleeve in time, and they are unable to replace the damaged rubber sleeve in time. In this way, various impurities such as moisture and dust in the external environment will pass through the rubber sleeve. The damaged part of the rubber sleeve will enter the inside of the antenna and then attach to the antenna body and other related components. The occurrence of this situation will undoubtedly increase the equivalent resistance of the antenna, and ultimately lead to a significant weakening of the antenna's strength when receiving and transmitting signals. In addition, it should be noted that underground surface wells are often equipped with related equipment such as water pumps. These devices will produce relatively strong vibrations during operation. When this vibration is transmitted to the location of the external rubber stick antenna through a certain medium, it is very likely to cause the antenna to loosen. Once the antenna is loose, the stability and effect of its signal transmission will inevitably be seriously affected.

[0026] The operating principle of the present invention is now described as follows: before using the external rubber stick antenna, align the connecting frame 121 and the connecting tube 122, and sleeve the connecting tube 122 on the outside of the connecting frame 121. When the connecting frame 121 moves relatively in the connecting tube 122, the positioning plate 16 will continuously reciprocate downward through the mutual cooperation of the inclined surfaces of the ratchet teeth 17 between the positioning plate 16 and the connecting frame 121. When the connecting frame 121 is inserted into the set position in the connecting tube 122, the ratchet teeth 17 between the positioning plate 16 and the connecting frame 121 will be mutually matched. The positioning plate 16 and the connecting frame 121 are relatively fixed, so that the connecting frame 121 and the connecting tube 122 are fixed, and then the air supply pipe 23 and the supporting pipe 27 are connected by threaded connection, so that the air supply pipe 23 and the ring pipe 25 are connected, and then the separated shunt pipe 33 is connected by threaded connection (the shunt pipe 33 is a segmented structure, one section is connected to the air supply pipe 23, and one section is connected to the sealing cover 9, and the two sections are connected by threaded connection), and the inflatable component 20 and the external rubber stick antenna can be fixed; Next, the operator aligns the threaded sleeve 5 of the external rubber stick antenna with the installation position, then rotates the external rubber stick antenna, and installs the external rubber stick antenna on the Internet of Things device in the underground surface well by means of threaded connection, so that the center pin 6 is inserted into the antenna interface in the Internet of Things device. After the external rubber stick antenna is installed, the rubber ring 451 on the outside of the vertical ring 8 will be squeezed with the installation position, thereby sealing the installation port of the external rubber stick antenna. Then the operator transmits an electrical signal to the PLC controller 10 through the external remote control device (the external remote control device has a wireless transmission module, and the PLC controller 10 is provided with a wireless receiving module. This is an existing mature technology and will not be repeated in this article), and the PLC controller 10 will control The micro electric push rod 53 is controlled to work, and the micro electric push rod 53 will drive the moving frame 50 to move, and the moving frame 50 will drive the piston block 51 to move to the left, so that the air pressure in the space on the right side of the piston block 51 is reduced, and the air pressure in the space on the right side of the piston block 51 is connected to the annular cavity 46 through the bent pipe 452. When the air pressure in the space on the right side of the piston block 51 is reduced, the air pressure in the inner space of the annular cavity 46 will also be reduced, and the suction cup 48 is connected to the annular cavity 46. When the air pressure in the inner space of the annular cavity 46 is reduced, the air pressure in the inner space of the suction cup 48 will also be reduced synchronously, so that the suction cup 48 can be used to adsorb and fix the plate at the installation location, thereby increasing the stability of the installation of the external rubber stick antenna and reducing the probability of the external rubber stick antenna being loosened due to vibration; After the external glue stick antenna is installed, the sensing needle 412 will be squeezed by the plate at the installation location, so that the sensing needle 412 drives the moving seat 42 to move, and the moving seat 42 drives the conductive frame 43 and the conductive plate 44 to separate, and the conductive frame 43 is electrically connected to the external power supply, and the conductive plate 44 is electrically connected to the first indicator light 11. When the conductive frame 43 and the conductive plate 44 are separated, the circuit of the first indicator light 11 will be disconnected, so that the first indicator light 11 will go out. When the external glue stick assembly is loosened due to the vibration of other equipment, the distance between the plate at the installation location and the sensing tube 411 will increase. Under the action of the spring force, the moving seat 42 will drive the sensing needle 412 and the conductive frame 43 to move toward the conductive plate 44, so that the conductive frame 43 and the conductive plate 44 contact, so that the first indicator light 11 will glow again. When the maintenance personnel subsequently maintain the equipment, after seeing the first indicator light 11 is on, they will reinforce the installation of the external glue stick antenna. When the PLC controller 10 controls the micro electric push rod 53 to move, the PLC controller 10 will also control the micro air pump 21, the first control valve 31, the regulating valve 37 and the second solenoid valve 35 to work. The micro air pump 21 transports the argon in the argon compression box 30 to the sealing cover 9 through the shunt pipe 33. Since the density of argon is 1.784kg / m³, and the density of air is 1.293kg / m³, the density of argon is lower than that of air. When the argon is transported to the sealing cover 9, the air will be squeezed upward, so that the air and moisture inside the sealing cover 9 are discharged through the outlet pipe 36. When the micro air pump 21 works for a set time, the PLC controller 10 will control the regulating valve 37 and the second solenoid valve 35 to close, so that the sealing cover 9 is filled with argon. Argon is an inert gas with very stable chemical properties. It hardly reacts chemically with other substances at room temperature and under general conditions, so as to avoid oxidation of metal parts (such as copper, aluminum, tin, etc.) of the components at the interface of the external glue stick antenna, thereby extending the service life of the components at the interface. When the regulating valve 37 and the second solenoid valve 35 are closed, the PLC controller 10 controls the first control valve 31 to close, and controls the second control valve 32 and the first solenoid valve 34 to open, so as to deliver the external gas to the air supply pipe 23, and deliver the gas to the inflation chamber 24 through the support pipe 27, the annular pipe 25 and the gas outlet head 26, so that the inflation chamber 24 expands, and the air pressure inside the air supply pipe 23 and the inflation chamber 24 is detected by the barometer 28 (the air supply pipe 23 and the inflation chamber 24 are connected, and the air pressure inside the air supply pipe 23 is detected, which is also equivalent to the air pressure inside the inflation chamber 24). When the barometer 28 detects that the air inside the inflation chamber 24 is When the pressure reaches the set threshold, the barometer 28 will control the micro air pump 21 to stop working through the PLC controller 10, and control the second control valve 32 and the first electromagnetic valve 34 to close, so that a certain air pressure is maintained in the inflation chamber 24. While improving the pressure resistance of the rubber stick antenna, it can also alleviate the excessive expansion pressure of the rubber sleeve 4 due to thermal expansion to a certain extent, prevent the rubber sleeve 4 from rupture due to excessive expansion, and when the temperature drops, the gas shrinks, which can fill the gap that may appear due to the cold shrinkage of the rubber sleeve 4, reduce the chance of external cold air, water vapor, etc. entering the rubber sleeve 4, and help maintain a relatively stable environment inside the rubber sleeve 4; When the surface of the rubber sleeve 4 is cracked due to aging, the gas inside the air chamber 24 will be discharged through the cracks, and the barometer 28 will detect this situation. When the barometer 28 detects that the air pressure inside the air chamber 24 is reduced, the barometer 28 will send an electrical signal to the PLC controller 10. After the PLC controller 10 receives the electrical signal, the PLC controller 10 will control the micro-transfer pump 39 and the solenoid valve to work, and control the second indicator light 29 to light up (the operator will find the first indicator light when the equipment is repaired later). When the second indicator light 29 lights up, it is known that the rubber sleeve 4 needs to be replaced in time. The micro delivery pump 39 delivers the tire repair liquid in the storage box 38 to the ring tube 25 through the air delivery pipe 23, and sprays it out through the air outlet head 26, so that the tire repair liquid is delivered to the inflation chamber 24. The main components of the tire repair liquid include fiber materials and sealant. After the tire repair liquid is delivered to the inflation chamber 24, the tire repair liquid flows to the damaged part under the action of the air pressure inside the inflation chamber 24. The fiber materials therein are like countless tiny "patches", which will be The holes are intertwined with each other, and the sealant in the tire repair fluid will further fill the gaps of the holes on the basis of the fibers. The sealant is usually a viscous polymer material, which can be tightly attached to the rubber surface and fibers of the rubber sleeve 4. After contacting the air, the sealant will gradually solidify to form a relatively stable sealing structure, just like forming a soft but tough "plug" at the hole, effectively sealing the hole in the rubber sleeve 4. When the micro-delivery pump 39 delivers a certain amount of tire repair fluid, the PLC controller 10 will control the micro-delivery pump 39 to stop working and control the electric control valve 40 to close. Then the PLC controller 10 controls the micro-air pump 21, the second control valve 32 and the first solenoid valve 34 to work, so that the micro-air pump 21 delivers external gas to the inflation chamber 24, so that the inflation chamber 24 continues to maintain the set air pressure, and also uses the air pressure to deliver the remaining tire repair fluid in the air supply pipe 23 to the inflation chamber 24, so as to avoid the tire repair fluid accumulating in the air supply pipe 23 and solidifying, which will cause the problem of blockage inside the air supply pipe 23.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
