Description

Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas (LPG) equipment technology, and in particular to a distributed partition wall gas delivery system. Background Technology

[0002] Currently, traditional natural gas supply has achieved pipeline delivery, but it requires excavating municipal roads and using building facades for overhead installation. In some areas where natural gas users are not very concentrated, laying gas supply networks is costly, so liquefied petroleum gas is still used as fuel.

[0003] Currently, because liquefied petroleum gas (LPG) needs to be stored and transported in a liquid state to greatly improve efficiency, and the liquid volume is only about 1 / 250 of the gas volume, special pressure vessels such as storage tanks, gas cylinders (steel cylinders), and tank truck bodies are commonly used.

[0004] These pressure vessels need to withstand the saturated vapor pressure of LPG under varying ambient temperatures and ensure long-term reliable operation at specified design pressures and safety factors. Their structural design, material selection, manufacturing processes, and inspection standards are all subject to strict regulations. However, most storage tanks and gas cylinder storage equipment on the market are installed by users themselves, using simple storage racks or cabinets. These devices have significant shortcomings in terms of cylinder stability, gas leak protection, and ease of operation.

[0005] The current decentralized use of gas cylinders has many disadvantages, mainly reflected in the following aspects: 1. After the liquefied petroleum gas in the cylinders is used up, it needs to be replaced at home, or the user needs to take it to a gas exchange station for replacement and then bring it back to the place of use. This is inconvenient and cannot be used continuously. There are risks of leakage and explosion during the gas storage, transportation and use process; 2. After the gas is replaced, the disassembly / connection at the place of use is done by the user. The gas users are relatively complex, and there are many errors due to human operation. Generally, users lack professional operation training and knowledge. When the gas cylinder is replaced, the connection / disassembly process of the pressure reducing valve or regulator and the gas cylinder valve may cause leakage or damage to the interface due to thread design, difficulty in alignment or improper operation. When a small leak occurs, it can easily accumulate to the explosion limit in a closed or semi-closed room, endangering the main building and the safety of people and property; 3. The gas cylinders are close to open flames and high-temperature heat sources such as stoves indoors, which can easily cause ignition risk; 4. After the gas is used up, the gas cylinders need to be distributed, which makes it difficult to manage in a standardized manner. Summary of the Invention

[0006] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a distributed partition wall gas supply system.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A distributed wall-mounted gas supply system includes a storage cabinet, gas cylinders, and a manifold assembly. The storage cabinet contains multiple gas cylinders, each connected to the other via an inlet end of the manifold assembly. The outlet end of the manifold assembly is connected to a rigid pipe. The manifold assembly is installed inside the storage cabinet. The rigid pipe is equipped with a first emergency shut-off valve. The rigid pipe passes through walls, and a sleeve assembly is provided between the rigid pipe and the wall, leading into the user's room. The user end of the rigid pipe is connected to the gas appliance via a first flexible pipe.

[0008] Specifically, the storage cabinet has a fixed bottom edge on the outer side of its bottom surface, which is fixed to the connecting plate with bolts.

[0009] Specifically, the storage cabinet has a bottom ventilation window on its bottom surface or the bottom of its side surface, and an upper ventilation window on the upper part of its side surface.

[0010] Specifically, the gas tank is connected to the manifold assembly via a second flexible pipeline. The second flexible pipeline is equipped with a pressure reducing valve and a second emergency shut-off switch. The manifold assembly is equipped with a manifold conversion valve, and the rigid pipeline is equipped with a pre-meter valve at the user end.

[0011] Specifically, the sleeve assembly includes an outer sleeve and an inner sleeve, which are fitted over the rigid pipe. A sealing material is provided between the outer sleeve, the inner sleeve and the rigid pipe. The outer sleeve and the inner sleeve are located on opposite sides of the wall. The front end of the inner sleeve is inserted into the outer sleeve. The end of the outer sleeve connected to the inner sleeve has a conical cavity inside. The outer side of the inner sleeve is a conical head, which is inserted into the conical cavity.

[0012] Specifically, the inner sleeve has a first outer edge at its rear end, the outer sleeve has a second outer edge at its outer end, and the end face of the outer sleeve near the inner sleeve has multiple threaded holes. The fastening bolt passes through the mounting hole of the first outer edge of the inner sleeve and is fitted into the threaded hole of the outer sleeve to fix the inner sleeve and the outer sleeve together.

[0013] Specifically, it also includes a main controller, which is connected to the cabinet detector alarm and the measuring instrument, the main controller is connected to the indoor controller, the indoor controller is connected to the indoor detector alarm, the plug of the indoor controller is connected to the explosion-proof socket, the explosion-proof socket is connected to the municipal power grid, the main controller is also connected to the audible and visual electronic sentinel, and the measuring instrument is installed on the rigid pipes or flexible pipes in the user's room.

[0014] Specifically, the storage cabinet is assembled on a connecting plate, and a plurality of parallel crossbeams are provided below the connecting plate, with the crossbeams fixedly mounted on a fixed base.

[0015] Specifically, the fixed bottom edge and the connecting plate are fixed by a fixing mechanism, which includes an n-shaped frame, a buffer, and a pin. The two arms of the n-shaped frame have pin holes near their lower ends. The fixed bottom edge and the connecting plate have corresponding through holes. The two arms of the n-shaped frame pass through the fixed bottom edge and the through holes of the connecting plate in sequence. The buffer is located between the fixed bottom edge and the horizontal plate of the n-shaped frame.

The pin hole extends from the lower surface of the connecting plate, and the pin is inserted into the pin hole to detachably connect the fixed bottom edge and the connecting plate together.

[0016] Specifically, the latch is a U-shaped lock, which can serve as an anti-theft measure when installed outdoors where no one is managing the property.

[0017] The beneficial effects of this utility model are as follows: 1. Setting up storage cabinets outdoors with rigid pipes connecting them to the house offers advantages over traditional indoor storage of gas cylinders, including safer space, better ventilation, more sensitive leak alarms, more convenient emergency response, less disruption to users, and prevention of secondary combustion and explosion. 2. By installing combustible gas detectors in storage cabinets and indoors, and electromagnetic gas emergency shut-off valves on connecting pipes, prevention, mitigation, and rescue are combined to reduce risks and hazards, mitigate the harm of accidents, and prevent the spread of accidents. 3. Rigid pipes pass through the wall, reducing the need for additional sleeve components. The sleeve length is equivalent to the wall thickness. An elastic, corrosion-resistant, and waterproof sealing material is installed between the gas pipe and the sleeve. For easy installation and disassembly, the sleeve is designed with a self-locking structure. 4. The storage cabinet can be detached and fixed to the base, making it easy to install with a forklift or lifting equipment. The fixing mechanism can achieve quick assembly and disassembly. The buffer in the fixing mechanism can buffer assembly accuracy problems caused by thermal expansion and contraction. It can also play a certain buffering role during the replacement of gas canisters, reducing fatigue wear of connecting parts and extending their service life.

[0018] In summary, this utility model significantly reduces safety risks, improves emergency response efficiency, makes gas use more convenient and continuous, provides precise metering, enhances energy dispatching capabilities, improves kitchen and bathroom environments, reduces human error, and facilitates standardized management by gas companies.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Example 1 like Figure 1 , 2 As shown in Figures 3 and 4, a distributed wall-mounted gas supply system includes a storage cabinet 1, gas cylinders 2, and a manifold assembly 3. The storage cabinet 1 houses multiple gas cylinders 2, which are connected to each other via the inlet end of the manifold assembly 3. The outlet end of the manifold assembly 3 is connected to a rigid pipe 4. The manifold assembly 3 is installed inside the storage cabinet 1. A first emergency shut-off valve 8 is installed on the rigid pipe 4. The rigid pipe 4 passes through a wall 13, and a sleeve assembly is provided between the rigid pipe 4 and the wall 13, leading into the user's room. The user end of the rigid pipe 4 is connected to a gas appliance 7 via a first flexible pipe 10. The storage cabinet 1 and gas cylinders 2 are maintained by the gas supply company. Multiple gas cylinders 2 facilitate maintenance; a cylinder 2 about to run out of gas can be shut off and replaced without affecting continuous use, ensuring continuous gas supply for the user. This system also enhances the professionalism of the gas supply company's staff and reduces the risk of operational errors.

[0029] Specifically, the storage cabinet 1 has a fixed bottom edge 103 on the outer side of its bottom surface. The fixed bottom edge 103 is fixed to the connecting plate 11 with bolts. The connecting plate 11 is welded to the channel steel or fixed to the cement platform. The door of the storage cabinet 1 is equipped with a lock. The lock is existing technology and can be an electronic door lock with an emergency switch. The choice can be made according to the actual situation.

[0030] Specifically, the storage cabinet 1 has a lower ventilation window 101 on its bottom or side bottom and an upper ventilation window 102 on its upper side for heat dissipation.

[0031] Specifically, the gas tank 2 is connected to the manifold assembly 3 via a second flexible pipeline. The second flexible pipeline is equipped with a pressure reducing valve 201 and a second emergency shut-off switch 202. The manifold assembly 3 is equipped with a manifold conversion valve, which is a prior art technology that allows for reasonable selection based on the number of pipelines. The rigid pipeline 4 is equipped with a pre-meter valve 5 at the user end. The pre-meter valve 5 can adjust the gas flow rate and the gas source switch, making it safer to use. A ball valve 19 is also provided at the end of the second flexible pipeline near the manifold assembly 3. The ball valve is a ball-shaped disc handle valve used to manually close the second flexible pipeline for easy replacement of the gas tank.

[0032] Specifically, the sleeve assembly includes an outer sleeve 1301 and an inner sleeve 1302. The outer sleeve 1301 and the inner sleeve 1302 are sleeved on the outside of the rigid pipe 4. A sealing material 1301 is provided between the outer sleeve 1301, the inner sleeve 1302 and the rigid pipe 4. The outer sleeve 1301 and the inner sleeve 1302 are located on both sides of the wall 13. The front end of the inner sleeve 1302 is inserted into the outer sleeve 1301. The end of the outer sleeve 1301 connected to the inner sleeve 1302 has a conical cavity 1305 inside. The outer surface of the inner sleeve 1302 is conical. The conical head 1306 is inserted into the conical cavity 1305. The conical head 1306 and the conical cavity 1305 achieve an optimal interference fit. The advantage of this setting is that during assembly, the outer sleeve is first passed from the outside of the wall 13 into the wall hole, and an appropriate amount of colloid sealant is injected. Then, the inner sleeve 1302 is inserted from the inside of the wall 13, and the colloid sealant is squeezed to fully fill the gap between the outer sleeve 1301, the inner sleeve 1302 and the rigid pipe 4. The excess can be squeezed out of the wall to achieve an effective sealing effect.

[0033] Specifically, the inner sleeve 1302 has a first outer edge 1307 at its rear end, and the outer sleeve 1301 has a second outer edge 1308 at its outer end. The outer sleeve 1301 has multiple threaded holes on its end face near the inner sleeve 1302. The fastening bolt passes through the mounting hole of the first outer edge of the inner sleeve 1302 and is fitted into the threaded hole of the outer sleeve 1301 to fix the inner sleeve 1302 and the outer sleeve 1301 together.

[0034] Specifically, it also includes a main controller, which is connected to the cabinet detector alarm 18 and the metering instrument 6 respectively. The main controller is connected to the indoor controller 16, and the indoor controller 16 is connected to the indoor detector alarm 17. The plug of the indoor controller 16 is connected to the explosion-proof socket 15, which is connected to the municipal power grid to play a certain protective role. The main controller is also connected to the audible and visual electronic sentinel 9, which is installed on the outside top of the storage cabinet 1 for early warning and to alert the surrounding personnel of gas leaks. The indoor detector alarm 9 and the cabinet detector alarm 901 are equipped with combustible gas detectors. The metering device 6 is a turbine flow meter or an IoT-based LPG meter with an accuracy class of 1.5, enabling individual metering and supporting both prepaid and postpaid modes. The metering device 6 is installed on the rigid pipe 4 or the flexible pipe 10 inside the user's room. The cabinet detector alarm 18, the indoor detector alarm 17, and the metering device 6 are all existing technologies and can be directly purchased and used; their structures are not detailed here. The indoor detector alarm 17 is installed inside the user's room and connected to the indoor controller 16 to detect the indoor gas content. If it exceeds a set value, an alarm is triggered, and the alarm is transmitted to the main controller via the indoor controller 16. The main controller then closes the first emergency shut-off valve 8. The cabinet detector alarm 901 is installed inside the storage cabinet 1 and directly connected to the main controller. It monitors the gas content inside the storage cabinet 1. If it exceeds the limit, the second emergency shut-off valve 202 is closed to minimize leakage, and the audible and visual electronic sentry 9 is activated for early warning, reducing potential risks, mitigating accident hazards, and preventing the spread of accidents. Figure 4 The main controller shown can be connected to the gas supply company's management platform through a gateway to facilitate intelligent management. Explosion-proof fans 14 can be installed inside the storage cabinet 1 as needed. The controller can also control the explosion-proof fans 14 to dissipate heat and cool the storage cabinet 1. The explosion-proof fans 14, the main controller, the audible and visual electronic sentry 9, and the cabinet probe alarm 17 are powered by a dual-circuit explosion-proof battery installed inside the storage cabinet 1.

[0035] Example 2 like Figure 5 , 6 The diagram shows a distributed partition wall air supply system, in which a storage cabinet 1 is mounted on a connecting plate 11. Below the connecting plate 11, there are multiple parallel crossbeams 1101. The crossbeams 1101 are fixed on a fixed base 1102. The fixed base 1102 can be a fixed cement floor or a suitable location such as an equipment platform. The crossbeams 1101 can support the bottom of the storage cabinet 1, which facilitates ventilation and heat dissipation and prevents water accumulation.

[0036] Specifically, the fixed bottom edge 103 and the connecting plate 11 are fixed together by a fixing mechanism 12. The fixing mechanism 12 includes an n-shaped frame 1201, a buffer 1202, and a pin 1203. The two arms of the n-shaped frame 1201 have pin holes near their lower ends. Figure 6 As shown, the fixed bottom edge 103 and the connecting plate 11 are respectively provided with through holes. The two arms of the n-shaped frame 1201 pass through the through holes of the fixed bottom edge 103 and the connecting plate 11 in sequence. The buffer 1201 is located between the fixed bottom edge 103 and the horizontal plate of the n-shaped frame 1201. The buffer 1202 adopts a spring or elastic rubber column. The pin hole protrudes from the lower surface of the connecting plate 11, and the pin 1203 is inserted into the pin hole. The fixing mechanism 12 can be detachably connected, and can play an elastic buffering role when the storage cabinet 1 is pushed by external forces such as strong winds and collisions, or buffer the stress generated by thermal expansion and contraction in places with large temperature differences, thus extending the service life.

[0037] Example 3 like Figure 7 The distributed partition wall gas supply system shown can use a U-lock for its latch 1203, which can serve as an anti-theft measure when installed outdoors in unattended locations.
