For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.
[0034] According to an embodiment of the utility model, a gas damper is provided, comprising:
[0035] The housing 1 has a cavity inside;
[0036] A piston 2 is slidably disposed in the cavity, and the piston 2 is suitable for dividing the cavity into a first cavity 101 and a second cavity 102, and the first cavity 101 is filled with combustible gas;
[0037] The ignition assembly 3 includes an igniter 31 located in the first cavity 101, and an electrifying plate 32 fixed to the side wall of the cavity. The electrifying plate 32 is electrically connected to the igniter 31 and is suitable for cooperating with the movement of the piston 2 to electrify so that when the speed of the piston 2 moving toward the first cavity 101 exceeds a preset value, the igniter 31 ignites the combustible gas.
[0038] The gas damper provided in this embodiment is formed by filling the first cavity 101 with combustible gas and arranging the igniter 31 in the first cavity 101. When the movement speed of the piston 2 toward the first cavity 101 exceeds a preset value, the igniter 31 ignites to ignite the combustible gas, so that the generated explosive gas force pushes the piston 2 back, thereby preventing the piston 2 from colliding with the inner wall of the shell 1.
[0039] Specifically, taking the use of a gas damper to reduce shock to the structural body as an example, the shell 1 is in the shape of a straight tube, and the outside of the shell 1 is wrapped with at least one layer of explosion-proof shell 11. The piston 2 is slidably arranged in the cavity to divide the cavity into a first cavity 101 and a second cavity 102. The first cavity 101 is filled with combustible gas, and a first hinge seat 13 is arranged at one end of the shell 1 outside close to the first cavity 101, and the first hinge seat 13 is suitable for forming a hinge with the first structural body through a pin; the piston 2 is fixedly connected to a rod body 9 on the side facing the second cavity 102, the axis of the rod body 9 is parallel to the sliding direction of the piston 2, and a part of the rod body 9 slides out of the shell 1, and a second hinge seat 14 is arranged at the end of the rod body 9 away from the shell 1, and the second hinge seat 14 is suitable for forming a hinge with the second structural body through a pin. When an earthquake occurs and the first structural body and the second structural body produce relative displacement, the rod body 9 is suitable for driving the piston 2 to move in the cavity.
[0040] The above-mentioned combustible gas is a mixture of natural gas and oxygen-enriched air, and the volume ratio thereof is natural gas (admixed with 15%-20% hydrogen, liquid nano soft particles and catalyst-plated monolithic particles): oxygen-enriched air = 2:1, so that the natural gas burns by the Camisole effect, thereby reducing the proportion of incompletely burned particles.
[0041] The charging plate 32 is fixed to the side wall of the cavity. When the piston 2 moves toward the first cavity 101, the piston 2 and the charging plate 32 are relatively displaced and an electric signal is generated. The faster the piston 2 moves, the stronger the electric signal is, and the preset value of the piston 2 movement speed has a preset electric signal strength. When encountering a large vibration, when the electric signal generated by the movement of the piston 2 relative to the charging plate 32 exceeds the preset electric signal strength, it indicates that the movement speed of the piston 2 exceeds the preset value. At this time, the combustible gas is compressed, and the igniter 31 ignites to ignite the combustible gas inside the first cavity 101, thereby generating an explosive gas force to push the piston 2 in the opposite direction, greatly consuming the kinetic energy of the piston 2, thereby preventing the piston 2 from colliding with the inner wall of the shell 1, and providing effective shock-absorbing protection for the main structure under a large earthquake. The form of generating the electrical signal may be Hall induction, that is, the piston 2 is a magnetic part, and the charging plate 32 is constructed by a Hall induction module. By utilizing the Hall effect, when the piston 2 moves relative to the charging plate 32, an electrical signal is generated on the charging plate 32, and the faster the piston moves, the stronger the generated electrical signal is. The form of generating the electrical signal may also be as follows Figures 1 to 3 The triboelectric form shown.
[0042] In some embodiments, in combination Figures 1 to 3 As shown, the surface of the piston 2 is provided with a coating, the coating comprises an aluminum foil coating, the electrifying plate 32 comprises a Teflon plate, and the coating and the electrifying plate 32 are suitable for forming a friction electrification fit.
[0043] Specifically, the coating includes aluminum foil coating, fiber coating or polyamide coating, etc., and the charging plate 32 includes Teflon plate, polyester plate, polyisobutylene plate or polyurethane plate, etc. When the coating moves and rubs on the surface of the charging plate 32, one side gains charge and the other side loses charge, thereby generating a charge difference between the charging plate 32 and the coating. This charge difference is measured as an electrical signal through an external circuit (it should be noted that the measurement of frictional electric signals belongs to the prior art and will not be repeated here), and the faster the coating moves relative to the charging plate 32, the stronger the generated electrical signal. Figure 2 and Figure 3 As shown, the charging plate 32 includes a symmetrically arranged friction positive plate 321 and a friction negative plate 322. The coating is equivalent to the movement of the charging plate 32 and generates different electrical signals with the friction positive plate 321 and the friction negative plate 322, so as to maximize the charge difference between the coating and the charging plate 32.
[0044] In some embodiments, in combination Figures 1 to 3 As shown, the ignition assembly 3 also includes a power supply assembly 33, which is electrically connected to the electrification plate 32 and the igniter 31, so as to supply power to the igniter 31 when the movement speed of the piston 2 exceeds a preset value.
[0045] Specifically, the power supply assembly 33 includes an electrically connected power supply and a control circuit, and the control circuit is electrically connected to the electromotive plate 32 to determine whether the electrical signal generated by the relative movement of the piston 2 and the electromotive plate 32 exceeds a preset value. The power supply includes a battery or a generator, such as a friction generator, and the power supply is electrically connected to the igniter 31. When the control circuit determines that the strength of the electrical signal exceeds the preset value, the control power supply supplies power to the igniter 31, so that the igniter 31 ignites the combustible gas inside the first cavity 101. It should be noted that the circuit for determining whether the strength of the electrical signal exceeds the preset value and controlling whether the power supply supplies power to the electrical device according to whether the condition is met belongs to conventional technical means and will not be repeated here.
[0046] In some embodiments, in combination Figures 1 to 3 As shown, the position of the piston 2 before compressing the combustible gas is defined as the initial position, the area of the cavity side wall close to the initial position is fixedly connected with the friction plate 12, the piston 2 is suitable for sliding and friction cooperation with the friction plate 12, and the charging plate 32 is arranged in the area of the cavity side wall away from the initial position and abuts against the friction plate 12.
[0047] The gas damper provided in this embodiment sets a friction plate 12 in the area near the initial position of the cavity side wall, so as to initially consume energy for the movement of the piston 2 through friction and compression of the combustible gas, which has higher energy consumption efficiency than only consuming energy through compressed gas.
[0048] Specifically, when the vibration is small, the piston 2 moves toward the first cavity 101 under the push of the rod body 9. At this time, the piston 2 rubs against the friction plate 12 arranged near the initial position and gradually compresses the combustible gas inside the first cavity 101, so as to dissipate energy through friction and compressed gas. Compared with the ordinary gas damper or friction damper in the related art that only dissipates energy through compressed gas or friction, it has a dual-mechanism energy dissipation form, which is conducive to improving the damping effect under small shocks. Preferably, the friction plate 12 is arranged on the inner wall of the cavity around the axis of the rod body 9, thereby increasing the contact area between the piston 2 and the friction plate 12, which is conducive to improving the friction damping effect.
[0049] In some embodiments, in combination Figures 1 to 3 As shown, a first one-way valve 5 is provided on the side wall of the shell 1 corresponding to the first cavity 101, and the gas damper also includes an exhaust gas bin 4, which is connected to the first cavity 101 via the first one-way valve 5. The first one-way valve 5 is suitable for allowing the gas in the first cavity 101 to flow to the exhaust gas bin 4 in one direction.
[0050] The gas damper provided in this embodiment is provided with a first one-way valve 5 so that after the combustible gas is ignited, the first one-way valve 5 is pushed open by the pneumatic force, thereby allowing the exhaust gas in the first cavity 101 to flow into the exhaust gas bin 4 and preventing the exhaust gas in the exhaust gas bin 4 from flowing back to the first cavity 101.
[0051] Specifically, the first one-way valve 5 is suitable for allowing the gas in the first cavity 101 to flow unidirectionally to the waste gas bin 4. After the igniter 31 ignites the above-mentioned combustible gas, the explosive gas force generated pushes open the first one-way valve 5, so that the waste gas after the combustion of the first cavity 101 can enter the waste gas bin 4 through the first one-way valve 5, and under the one-way flow action of the first one-way valve 5, the waste gas in the waste gas bin 4 is prevented from flowing back into the first cavity 101.
[0052] In some embodiments, in combination Figures 1 to 3 As shown, a condenser tube 6 is arranged around the outer wall of the shell 1 , and the condenser tube 6 is suitable for cooling the shell 1 .
[0053] The gas damper provided in this embodiment is configured with a condenser pipe 6 surrounding the outer wall of the shell 1 to cool the shell 1 .
[0054] Preferably, the condenser 6 is arranged between the explosion-proof housing 11 and the shell 1, and is arranged around the outer wall of the shell 1 for multiple circles, so as to cool the shell 1 whose temperature rises due to the combustion of the combustible gas, thereby preventing the shell 1 from overheating.
[0055] In some embodiments, in combination Figures 1 to 3 As shown, the gas damper also includes an air suction machine 15 and a compression condensation component. The air inlet of the air suction machine 15 is connected to the waste gas bin 4, and the air outlet of the air suction machine 15 is connected to the compression condensation component, so as to be suitable for introducing the gas in the waste gas bin 4 into the compression condensation component; the compression condensation component is connected to the condensation pipe 6, so as to be suitable for compressing and condensing the gas from the air suction machine 15 and then inputting it into the condensation pipe 6.
[0056] The gas damper provided in this embodiment compresses and condenses the exhaust gas inside the exhaust gas bin 4 into liquid through the suction machine 15 and the compression condensation component, and inputs it into the condensation pipe 6 to cool the shell 1, which can achieve the effect of exhaust gas recycling, is beneficial to saving condensation materials, and realizes resource recycling.
[0057] Specifically, the compression condensation component includes a compressor and a condenser. The air suction machine 15, such as an electric air suction machine, is suitable for introducing the waste gas (mainly CO2) in the waste gas bin 4 into the compression condensation component. The compression condensation component is suitable for pressurizing and cooling the waste gas to become liquid CO2, and inputting the liquid CO2 into the condenser 6 to cool the shell 1 to achieve the effect of CO2 recycling. The outlet of the condenser 6 is connected to the waste gas bin 4, so that the liquid CO2 can be returned to the waste gas bin 4 after absorbing heat and gasifying, so as to achieve resource recycling and save condensing materials. The waste gas bin 4 is detachably connected to the shell 1, so as to collect the waste gas whose main component is CO2 through the waste gas bin 4. Using carbon capture technology, the collected CO2 can be sealed or used for other industrial purposes, thereby reducing carbon dioxide emissions, which is conducive to alleviating the greenhouse effect and achieving the dual carbon goals.
[0058] In some embodiments, in combination Figures 1 to 3 As shown, a second one-way valve 8 is also provided on the side wall of the shell 1 corresponding to the first cavity 101. The gas damper also includes an air intake bin 10 storing combustible gas. The air intake bin 10 is connected to the first cavity 101 via the second one-way valve 8. The second one-way valve 8 is suitable for allowing the gas in the air intake bin 10 to flow to the first cavity 101 in one direction.
[0059] Specifically, the air intake bin 10 stores high-pressure combustible gas, and the second one-way valve 8 is suitable for allowing the gas in the air intake bin 10 to flow unidirectionally to the first cavity 101. The one-way flow may be in the form of, after the gas in the first cavity 101 flows into the waste gas bin 4, the air pressure in the first cavity 101 decreases, at which time the air pressure in the air intake bin 10 is greater than the air pressure in the first cavity 101, and the second one-way valve 8 opens under the action of the air pressure to allow the combustible gas in the air intake bin 10 to enter the first cavity 101; the one-way flow may also be in the form of controlling the opening of the second one-way valve 8 by a circuit as described below.
[0060] In some embodiments, in combination Figures 1 to 3 As shown, the waste gas bin 4 is provided with a pressure sensor 7, which is electrically connected to the second one-way valve 8. The pressure sensor 7 is suitable for controlling the second one-way valve 8 to open when it detects that the gas pressure in the waste gas bin 4 reaches a preset value.
[0061] Specifically, a detection circuit is electrically connected between the pressure sensor 7 and the second one-way valve 8. When the combustible gas in the first cavity 101 is ignited, a huge pneumatic force is generated, and the first one-way valve 5 is pushed open by the pneumatic force, and the exhaust gas flows into the exhaust gas bin 4 through the first one-way valve 5. At this time, the detection circuit detects that the pressure inside the exhaust gas bin 4 reaches a preset value through the pressure sensor 7 in the exhaust gas bin 4, and controls the second one-way valve 8 to open, so that new combustible gas enters the first cavity 101. It should be noted that the detection circuit that receives the signal of the sensor and controls the action of the actuator after logical judgment belongs to conventional technical means and will not be repeated here. In addition, the first one-way valve 5 and / or the second one-way valve 8 can be a Tesla valve.
[0062] In some embodiments, in combination Figures 1 to 3 As shown, the ignition assembly 3 is connected to the IoT system signal so that the user can monitor the movement speed of the piston 2 through the IoT system.
[0063] The gas damper provided in this embodiment is connected to the Internet of Things system signal through the ignition component 3, so that the user can remotely monitor the movement speed of the piston 2.
[0064] Specifically, the piston 2 and the electrifying plate 32 move relative to each other to generate an electrical signal, which is transmitted to the data acquisition industrial control instrument through the signal transmitter, and then transmitted to the Internet of Things system via the data acquisition industrial control instrument. The signal is analyzed and integrated by the Internet of Things system to determine the movement speed of the piston 2, and thus the vibration level is determined by monitoring the movement speed of the piston 2, thereby monitoring the health of the structural body (it should be noted that the data acquisition industrial control instrument and the Internet of Things system are both existing technologies), which is convenient for users to remotely monitor the movement speed and vibration level of the piston 2 toward the first cavity 101 through the Internet of Things system, and monitor the health of the structural body.
