DETAILED DESCRIPTION

[0017] The following will be combined with the attached Figure 1 To Attachment Fig. 9 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] A barrier explosion-proof skid-mounted filling device, comprising a protective box 1, an oil storage tank 3 and a cleaning mechanism 4, and also comprising a side box 2 fixedly mounted on one side of the protective box 1, the oil storage tank 3 being fixedly mounted inside the protective box 1 through a support frame, one end of the oil storage tank 3 being embedded in the inner wall of the side box 2, the oil storage tank 3 being composed of an outer shell 301 and an inner shell 302, and adopting a double-layer structure, the inner shell 302 being a corrosion-resistant alloy, and the corrosion-resistant alloy being adopted, the outer shell 301 being wrapped with a fireproof and heat-insulating layer; Among them, the side wall of the side box 2 is fixedly installed with an electrostatic grounding alarm, which is connected to the oil truck and the tanker 202. It determines whether the electrostatic conduction is effective by detecting the grounding resistance value between the explosion-proof skid-mounted filling device and the vehicle. When the grounding resistance exceeds the safety standard (usually ≤10Ω), the alarm immediately sends out an audible and visual signal to prompt the operator to stop the operation to avoid sparks caused by static discharge; when poor grounding is detected, the explosion-proof oil unloading pump is automatically shut down to stop pumping to prevent the continuation of dangerous operations; The shell 301 is made of carbon steel, and the fireproof and heat-insulating layer is made of ceramic coating. Carbon steel has good mechanical strength and heat resistance, and the ceramic coating on its surface significantly improves its high temperature resistance and heat insulation performance, effectively preventing heat from being transferred to the outside, thereby protecting the internal structure and items from high temperature damage; when a fire occurs outside the oil storage tank 3, the ceramic coating can quickly form a dense insulation layer to prevent the external high temperature from being transferred to the inside, and at the same time, the carbon steel shell can also withstand a certain temperature of heat without being easily deformed or damaged, ensuring the stability of the overall structure and lasting fireproof and heat-insulating performance; the operation process of the entire system is: once the ambient temperature rises to a certain threshold, the ceramic coating responds quickly, cutting off the heat conduction path through physical isolation, and at the same time, the carbon steel shell gradually improves its heat conduction capacity to assist in heat dissipation. The dual protection mechanism ensures safety and effectiveness in extreme fire conditions; The cleaning mechanism 4 is rotatably mounted inside the oil storage tank 3. The cleaning mechanism 4 is composed of a mounting tube 401, two mounting plates 404, a transmission assembly 405, a telescopic cleaning assembly 406 and a reciprocating screw rod 408, wherein the two mounting plates 404 are respectively fixedly mounted at both ends of the mounting tube 401, a slide rail groove 407 is provided on the inner wall of one side of the mounting tube 401, and the reciprocating screw rod 408 is rotatably mounted on one side inside the mounting tube 401, and a wire sleeve 409 is sleeved on the outer side of the reciprocating screw rod 408, and the wire sleeve 409 extends out of the mounting tube 401 through the slide rail groove 407, the telescopic cleaning assembly 406 is fixedly mounted inside the wire sleeve 409, and the transmission assembly 405 is fixedly mounted inside the wire sleeve 409. Component 405 is composed of a motor 4051, a fixed toothed disc 4052, and a planetary toothed disc 4053, wherein the motor 4051 is fixedly mounted on one side of the housing 301, and the output end of the motor 4051 is fixedly connected to one side of one of the mounting discs 404 through a shaft, and the shaft at the output end of the motor 4051 passes through the fixed toothed disc 4052, the planetary toothed disc 4053 is fixedly mounted on one side of the mounting disc 404, one side of the planetary toothed disc 4053 is fixedly connected to one end of the reciprocating screw rod 408, one side of the planetary toothed disc 4053 is meshedly connected with the fixed toothed disc 4052, and the fixed toothed disc 4052 is fixedly mounted on the inner wall of the housing 301 through a mounting frame; The motor 4051 drives the mounting tube 401 to rotate through the mounting plate 404, and the rotating mounting tube 401 drives the planetary gear plate 4053 to perform planetary rotation through the reverse meshing fixed gear plate 4052, and the rotating planetary gear plate 4053 drives the reciprocating screw rod 408 to rotate, and the rotating reciprocating screw rod 408 drives the thread sleeve 409 to perform reciprocating linear motion inside the mounting tube 401 through the slide rail groove 407, and the reciprocating linear motion thread sleeve 409 drives the telescopic cleaning component 406 to perform horizontal reciprocating movement, and performs telescopic cleaning operations along the inner surface of the oil storage tank 3. The problem of difficult cleaning of oil stains inside the oil storage tank 3 is effectively solved, and the work efficiency and cleaning quality are improved; at the same time, the rotating mounting tube 401 drives the telescopic cleaning component 406 to rotate through the reciprocating screw rod 408 and the thread sleeve 409, so that the telescopic cleaning component 406 rotates and moves horizontally at the same time, thereby achieving the purpose of covering and cleaning the inner wall of the inner shell 302, and the telescopic cleaning component 406 can be used to fit the inner wall curved surface of the inner shell 302 to avoid cleaning dead corners, ensure the quality and safety of the stored oil, and the cleaning mechanism 4 reduces the frequency of manual cleaning in the tank and reduces the operation risk; A plurality of distribution brackets 402 are equidistantly installed on the outside of the installation tube 401, wherein a trapezoidal barrier explosion-proof component 403 is clamped and installed between every two distribution brackets 402, and a trapezoidal barrier explosion-proof component 403 is not clamped and installed between two brackets 402 located on one side of the slide rail groove 407; Among them, the density of the trapezoidal barrier explosion-proof component 403 gradually decreases from the center of the oil storage tank 3 to the outer shell, forming an "energy buffer ring" to directly adsorb oil and gas and absorb the impact energy at the initial stage of the explosion. The trapezoidal barrier explosion-proof component 403 honeycomb aluminum alloy barrier explosion-proof material can quickly absorb and disperse the explosion energy, inhibit the explosion reaction of the oil and gas mixture, and reduce the flame propagation path by dividing the space; the evenly distributed trapezoidal barrier explosion-proof component 403 can ensure that the oil and gas molecules are in full contact with the barrier material, reduce the oil and gas concentration, and prevent it from reaching the explosion limit.

[0019] like Fig. 9 As shown, the telescopic cleaning assembly 406 is composed of a slide rod 4061, a sleeve rod 4062, a spring 4063 and a rubber scraper 4064, wherein the sleeve rod 4062 is movably sleeved on the outer side of one end of the slide rod 4061 through a slide groove, the spring 4063 is fixedly installed inside the sleeve rod 4062, one end of the spring 4063 is fixedly connected to the slide rod 4061, the other end of the spring 4063 is fixedly connected to the inner wall of the sleeve rod 4062, the rubber scraper 4064 is fixedly installed at one end of the sleeve rod 4062, and the rubber scraper 4064 is movably in contact with the inner wall of the inner shell 302; Among them, when the sleeve rod 4062 slides on the outside of the slide rod 4061, the spring 4063 fixed inside the sleeve rod 4062 is compressed or stretched due to the force, and follows the expansion and contraction, ensuring that the rubber scraper 4064 is always pressed tightly against the inner wall of the inner shell 302, effectively removing dirt and residues on the surface of the inner shell 302, keeping the inner shell clean and smooth, and improving the cleaning efficiency and effect.

[0020] like Figure 6 As shown, the trapezoidal barrier explosion-proof assembly 403 is composed of four trapezoidal metal honeycomb structures, and the four trapezoidal metal honeycomb structures are enlarged from the inside to the outside in the radial direction with the installation tube 401 as the center; Among them, the trapezoidal barrier explosion-proof component 403 achieves a good explosion-proof effect by means of four trapezoidal metal honeycomb structures that are successively enlarged and arranged from the inside to the outside around the installation tube 401. The trapezoidal metal honeycomb structure can effectively disperse and absorb energy. When the explosion shock wave or flame impacts the material group, the successively enlarged trapezoidal structure can gradually consume the energy of the shock wave to form an "energy ladder". The explosion shock wave is absorbed, reflected and dispersed layer by layer during the propagation process, avoiding the rupture of the oil storage tank 3 caused by single-point stress concentration and reducing its damage to the internal environment; at the same time, the porous design of the trapezoidal structure helps to quickly dissipate heat and orderly flow of air. The heat dissipation in the honeycomb structure is very strong, which can effectively prevent the further spread of the explosion. When an external explosion occurs, the explosion energy first acts on the innermost trapezoidal metal honeycomb structure, which consumes most of the energy by blocking, absorbing and transferring heat. The energy then gradually diffuses to the outer layer of the structure and is gradually weakened by the next layer of structure until the inner and outer layers work together to achieve a better protection effect. The trapezoidal metal honeycomb structure with a trapezoidal distribution extends the flame propagation path, and through heat exchange and physical isolation, the flame front speed is attenuated to below the safety threshold. The modular design of the trapezoidal metal honeycomb structure allows for partial replacement of damaged materials, reducing maintenance costs.

[0021] like Figures 1 to 3As shown, a refueling machine 202 is fixedly installed on one side of the side box 2, an automatic powder spraying fire extinguisher 201 is fixedly installed on the top of the side box 2, a nitrogen suppression explosion-proof device 205 is fixedly installed on the other side of the side box 2, and the nitrogen suppression explosion-proof device 205 is connected to the oil storage tank 3 through a control valve pipe, an explosion-proof oil unloading pump 203 is fixedly installed on one side of the side box 2, and an oil delivery port 204 is fixedly installed on one side of the explosion-proof oil unloading pump 203, and two temperature-controlled linkage valves 207 are fixedly installed on one end of the oil storage tank 3, and two temperature-controlled automatic shut-off valves 206 are respectively installed at the bottom of the two temperature-controlled linkage valves 207 through pipelines, one of which is connected to the output end of the explosion-proof oil unloading pump 203 through a pipeline, and the other temperature-controlled automatic shut-off valve 206 is connected to the refueling machine 202 through a pipeline; two oil and gas recovery valves 209 are fixedly installed above the temperature-controlled linkage valve 207, and an electronic control box 208 is fixedly installed on one side of the inner wall of the side box 2; Among them, two oil and gas recovery valves 209 are connected to the oil storage tank 3 through pipelines, and one of the oil and gas recovery valves 209 is connected to the fuel dispenser 202 through pipelines. When the fuel dispenser 202 discharges oil, the high-speed flow of oil produces a Venturi effect, which reduces the pressure in the fuel gun; the oil and gas in the vehicle fuel tank enter the oil and gas recovery valve through the pipeline under the action of the pressure difference, and the oil and gas recovery valve is designed with a pressure balancing diaphragm or float mechanism inside; when the pressure in the vehicle fuel tank is higher than the pressure in the oil storage tank 3, the diaphragm or float is lifted up, the valve is opened, and the oil and gas return to the storage tank through the recovery pipe; The electronic control box 208 has a high degree of safety protection function, which can monitor the operating status of the device in real time, detect abnormalities in time and take measures; The automatic powder spraying fire extinguisher 201 can be activated quickly when a fire occurs to put out the initial fire; Open the oil delivery port 204, the temperature-controlled automatic shut-off valve 206, and the temperature-controlled interlocking valve 207, connect the oil delivery port 204 to the tanker pipeline, and operate the explosion-proof oil unloading pump 203 to deliver the stored oil in the tanker to the inside of the oil storage tank 3 through the temperature-controlled automatic shut-off valve 206 and the temperature-controlled interlocking valve 207. The temperature-controlled automatic shut-off valve 206 and the temperature-controlled interlocking valve 20 have built-in thermistors. When the ambient temperature or the medium temperature exceeds a preset threshold (such as 70°C ± 5°C), the valve automatically closes to cut off the flow of oil. Therefore, when the oil storage tank 3 is heated and the internal oil temperature rises suddenly, the temperature-controlled automatic shut-off valve 206 and the temperature-controlled interlocking valve 207 immediately act to prevent the leakage of high-temperature oil and aggravate the fire.

[0022] like Figure 4 As shown, a plurality of partitions 303 are installed equidistantly between the outer shell 301 and the inner shell 302, and an aluminum foil heat insulation layer 304 is fixedly installed between every two partitions 303; Among them, the partition space formed by the outer shell 301 and the inner shell 302 can be divided into multiple independent spaces by the partition 303, and the aluminum foil insulation layer 304 has pores evenly distributed inside, which can absorb heat expansion energy. At the same time, the aluminum foil insulation layer 304 has a good insulation effect. The aluminum foil insulation layer 304 can block the heat radiation exchange between the inner shell 302 (corrosion-resistant alloy) and the outer shell 301 (carbon steel), avoiding the deformation of the inner shell due to thermal stress in high temperature scenes, and indirectly reducing the energy absorption pressure of the trapezoidal barrier explosion-proof component 403 by reducing the heat transmitted to the oil storage tank 3; In a fire scenario, the aluminum foil insulation layer 304 prolongs the time for the temperature in the oil storage tank 3 to rise to the flash point of the oil (such as gasoline -40°C) by 2-3 times, thereby gaining a critical window for emergency response; When used in cold regions, the aluminum foil insulation layer 304 can prevent the tank from being locally overheated due to direct sunlight and reduce the evaporation loss of oil.

[0023] When used in high-temperature environments, the aluminum foil insulation layer 304 can withstand continuous high temperatures (such as 70°C surface temperature in desert areas) and maintain a stable temperature inside the tank.

[0024] like Figures 1 to 5 As shown, a liquid level sensor, a pressure sensor, a temperature sensor, a combustible gas concentration sensor and a pressure relief valve are fixedly installed on the top of the oil storage tank 3 from right to left, and the liquid level sensor, the pressure sensor, the temperature sensor, the combustible gas concentration sensor and the pressure relief valve all extend to the top of the protection box 1; Among them, the pressure sensor monitors the pressure changes during the propagation of the explosion shock wave in real time and dynamically adjusts the pressure relief strategy. When the internal pressure of the storage tank is too high, the gas can be quickly discharged through the pressure relief valve to release the internal pressure and reduce the risk of explosion; when the temperature sensor detects abnormal temperature, the nitrogen suppression explosion-proof device 205 releases nitrogen to reduce the oxygen concentration to suffocate the flame; the combustible gas concentration sensor is used to detect the concentration of combustible gas. Once it is detected that the concentration exceeds the preset safety value, the system will respond quickly and start the pressure relief valve to release pressure to prevent explosion or fire, thereby ensuring the safe operation of the oil storage tank.

[0025] like Figures 2 to 5 As shown, a sewage hopper is provided at the bottom of the oil storage tank 3, and a sewage valve is fixedly installed on the front of the sewage hopper; Among them, the impurities and moisture in the oil storage tank 3 will gradually settle into the drain bucket, and then the operator will open the valve through the drain valve to allow the impurities and moisture to be smoothly discharged from the oil storage tank, thereby achieving the cleaning and maintenance of the oil storage tank and ensuring the purity of the oil in the oil storage tank.

[0026] According to the explanation and teaching of the above description, those skilled in the art to which the present invention belongs may also change and modify the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
