Description

Technical Field

[0001] This utility model relates to the field of gas transportation safety technology, and in particular to a gas transportation safety protection device. Background Technology

[0002] The gas transportation safety protection device is a gas leak detection and alarm system. This system is used to detect potential leaks during gas transportation, ensuring the safety of the transportation process. The system includes gas sensors, alarm devices, and a control module. The gas sensors can monitor the gas concentration around the transportation pipeline or container in real time. Once a gas leak or excessive concentration is detected, the system immediately triggers an alarm, alerting personnel to take emergency measures. Simultaneously, the system can be linked with automatic shut-off valves to promptly cut off the gas supply and prevent further escalation of the accident. Furthermore, the system can wirelessly transmit alarm information to a remote monitoring center for rapid response to hazardous situations. The application of this device can effectively prevent gas leak accidents, protect personnel safety, and reduce property damage.

[0003] Existing gas transport safety protection devices lack dual valves, which may prevent the rapid control of gas flow in the event of a leak, increasing the probability of accidents. Furthermore, relying on a single valve means that if the valve malfunctions or fails to close properly, the entire system may be unable to cut off gas flow in time, leading to further leaks or accidents. Existing devices also lack pressure detection structures within the device, making it impossible to monitor changes in gas pressure and detect abnormalities in pipelines or containers in a timely manner. Moreover, gas pipeline ruptures are often accompanied by rapid pressure changes, and a pressure detection system can identify such abnormal changes in advance, preventing dangerous situations from occurring.

[0004] Therefore, we propose a gas transportation safety protection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Existing devices lack a dual-valve protection structure, resulting in poor fault isolation capabilities. Furthermore, the design of a single valve may not meet stringent safety standards, especially in high-risk areas such as densely populated urban areas or industrial facilities, increasing the probability of accidents. Additionally, the transport structure lacks a pressure monitoring structure. Changes in internal air pressure are closely related to leaks in pipelines or equipment, and the lack of a pressure detection structure makes it difficult to detect leaks in a timely manner, preventing effective measures from being taken in the early stages of a leak, thereby increasing the scope and severity of the leak.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A gas transportation safety protection device includes a first protective shell, a second protective shell connected to the bottom of the first protective shell via a screw thread, a pressure detection ring disposed inside the first and second protective shells, and a display screen fixedly mounted on the top of the first protective shell. The display screen is electrically connected to the pressure detection ring, which monitors pressure changes within the device. When the gas pressure exceeds a predetermined range, the pressure detection ring can promptly sense it and feed back an electrical signal to the display screen. A flexible hose is disposed on the inner circumference of the pressure detection ring, and the outer circumference of the flexible hose is tightly fitted against the inner wall of the pressure detection ring. The flexible hose is used to conduct gas pressure and provide an effective pressure source for the pressure detection ring.

[0008] The first and second protective shells are respectively provided with a tank top and a tank bottom at both ends. The tank top and tank bottom are located at both ends of the first and second protective shells, respectively, and serve to seal and connect them. This structure has extremely high pressure resistance to prevent the device from breaking due to leakage or excessive pressure during gas transportation. A first flange is fixedly installed at both ends of the first and second protective shells. The first flange is located at both ends of the first and second protective shells and connects the tank top and tank bottom to the protective shell. The first flange is fixedly installed on the side of the tank top and tank bottom closest to the first and second protective shells. A second connecting pipe is fixedly connected to the end of the tank top away from the first flange. A double connecting pipe is provided on the side of the second connecting pipe away from the tank top. The second connecting pipe connects the tank top and the double connecting pipe and is the key channel for gas flow. A second flange is fixedly installed on the corresponding side of the double connecting pipe and the second connecting pipe. The design of the double connecting pipe can provide redundant connection pipes during gas transportation to prevent the impact of single pipe failure on the entire system. The two second flanges cooperate with each other.

[0009] The top of the dual-connecting pipe is fixedly connected to a first connecting pipe. A fixing ring is fixedly installed inside the dual-connecting pipe, serving a fixing and supporting function. Through its tight fit with the pipe, it ensures the stability of the pipe internals. A connecting rod is rotatably connected to the top of the fixing ring, and a first valve seat is fixedly connected to the bottom of the connecting rod. The connecting rod, through its rotatable connection with the fixing ring, provides a rotation mechanism, allowing the valve seat connected to the connecting rod to move and adjust. A second valve seat is fixedly connected to one side of the first valve seat, and movably connected to the second valve seat on the other side of the first valve seat. Through this structural design, the first valve seat can control the gas flow, blocking or allowing gas to pass through. The second valve seat is foldable. A knob is coaxially fixedly connected to the end of the connecting rod away from the first valve seat. The knob is located at the far end of the connecting rod, and its rotation controls the first valve seat, thereby regulating the gas flow.

[0010] Preferably, expansion rings are fixedly connected to both ends of the hose, and multiple fixing blocks are fixedly installed on the outer periphery of the two expansion rings. The fixing blocks ensure that the expansion rings can be firmly connected to other equipment or pipeline systems, and also facilitate the connection of the hose to the external environment.

[0011] Preferably, a telescopic rod is fixedly connected to the end of the fixed block away from the expansion ring. The distance can be adjusted by telescopic extension to adapt to the needs of hoses and connecting parts in different working environments. A fastening ring is fixedly connected to the end of the multiple telescopic rods away from the fixed block. The fastening ring ensures a tight fit between the telescopic rod and the protective shell and provides stable support. The outer periphery of the fastening ring is movably connected to the inner wall of the first protective shell and the second protective shell.

[0012] Preferably, a spring is fitted around the outer periphery of the telescopic rod to effectively prevent damage to the expansion ring caused by excessive stretching or compression. One end of the spring is fixedly connected to the fixing block, and the other end of the spring is fixedly connected to the inside of the fastening ring.

[0013] Preferably, a gas detector is fixedly installed on the outer periphery of the first flange, and the gas detector can issue a warning signal based on the detected gas concentration.

[0014] Preferably, the bottom of the second protective shell is movably connected to a base plate, and the bottom of the base plate is fixedly equipped with multiple self-locking casters. The self-locking casters can prevent the equipment from sliding or moving unintentionally, especially when the equipment is parked on a slope or uneven ground, it can effectively prevent the equipment from tilting due to sliding.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, on the one hand, by setting a pressure detection ring inside the first and second protective shells, the pressure detection ring detects the hose and transmits the electrical signal to the display screen. The electrical connection between the pressure detection ring and the display screen enables real-time monitoring of the gas inside the device, preventing the inability to take timely measures in case of leakage. On the other hand, by setting a two-way valve, a backup valve is provided when one valve malfunctions, enhancing the fault isolation capability of the structure and reducing the probability of accidents caused by gas leakage.

[0027] Example 1

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a gas transportation safety protection device, including a first protective shell 1, a second protective shell 2 connected to the bottom of the first protective shell 1 by a screw thread, a pressure detection ring 5 inside the first protective shell 1 and the second protective shell 2, the pressure detection ring 5 having a built-in pressure sensor to detect pressure changes in real time during gas transportation, the pressure detection ring 5 being connected to a display screen 6, and the system being able to issue an alarm to the operator through the display screen 6 when the pressure is abnormal (too high or too low), the display screen 6 being fixedly installed on the top of the first protective shell 1, the display screen 6 being electrically connected to the pressure detection ring 5, and a hose 3 being provided on the inner circumference of the pressure detection ring 5, the outer circumference of the hose 3 being tightly attached to the inner wall of the pressure detection ring 5;

[0029] The first protective shell 1 and the second protective shell 2 are respectively provided with a tank top 11 and a tank bottom 20 at both ends. The first protective shell 1 and the second protective shell 2 are connected by a first flange 7, which ensures the sealing of the entire device. The first flange 7 is fixedly installed at both ends of the first protective shell 1 and the second protective shell 2. The first flange 7 is fixedly installed on the side of the tank top 11 and the tank bottom 20 near the first protective shell 1 and the second protective shell 2. The first flange 7 is a key connecting component in the container or device, used to fix and seal the first protective shell 1, the second protective shell 2, the tank top 11, the tank bottom 20 and other components. The end of the tank top 11 away from the first flange 7 is fixedly connected to a second connecting pipe 21. The side of the second connecting pipe 21 away from the tank top 11 is provided with a double connecting pipe 12. The second connecting pipe 21 and the double connecting pipe 12 are used to connect different parts of the container, ensuring gas flow, pressure balance and safe discharge. The corresponding side of the double connecting pipe 12 and the second connecting pipe 21 is fixedly installed with a second flange 14, and the two second flanges 14 cooperate with each other.

[0030] The top of the double connecting pipe 12 is fixedly connected to the first connecting pipe 13. A fixing ring 15 is fixedly installed inside the double connecting pipe 12. A connecting rod 18 is rotatably connected to the top of the fixing ring 15. The fixing ring 15 is installed inside the double connecting pipe 12 to fix the connecting rod 18, ensuring its stable position and preventing displacement or rotational deviation during use. A first valve seat 16 is fixedly connected to the bottom of the connecting rod 18. A second valve seat 17 is fixedly connected to one side of the first valve seat 16, and the other side of the first valve seat 16 is movably connected to the second valve seat 17. The second valve seat 17 is foldable. A knob 19 is coaxially fixedly connected to the end of the connecting rod 18 away from the first valve seat 16. The knob 19 is located at the other end of the connecting rod 18 away from the first valve seat 16. It is part of the operating system and is used to manually adjust the position of the connecting rod 18, thereby moving the valve seat and controlling the opening and closing of the valve.

[0031] Example 2

[0032] Expansion rings 4 are fixedly connected to both ends of the hose 3. The expansion rings 4 are fixed to both ends of the hose 3, and their function is to enhance the connection between the hose and other components (such as the telescopic rod 24 and the protective housing). The expansion rings 4 may be annular metal or plastic components, providing a stable connection interface at both ends of the hose 3 to prevent the hose 3 from slipping or losing connection when subjected to external forces. Multiple fixing blocks 9 are fixedly installed on the outer periphery of the two expansion rings 4. The end of the fixing block 9 away from the expansion ring 4 is fixedly connected to the telescopic rod 24. The ends of the multiple telescopic rods 24 away from the fixing blocks 9 are fixedly connected to the fastening rings 8. The outer periphery of the fastening rings 8 is movably connected to the inner walls of the first protective housing 1 and the second protective housing 2. A spring is sleeved on the outer periphery of the telescopic rod 24. One end of the spring is fixedly connected to the fixing block 9, and the other end of the spring is fixedly connected to the inside of the fastening rings 8, ensuring that the system can flexibly adapt to different pressures or deformations during operation without affecting overall stability.

[0033] Example 3

[0034] A gas detector 10 is fixedly installed on the outer periphery of the first flange 7. The gas detector 10 is used to monitor the gas concentration in the working environment in real time. A base plate 22 is movably connected to the bottom of the second protective housing 2. The base plate 22 ensures that the equipment does not tilt or shift during operation. Multiple self-locking casters 23 are fixedly installed on the bottom of the base plate 22.

[0035] The working process of this utility model:

[0036] Step 1: By rotating the knob 19, the first valve seat 16, which is coaxially fixedly connected to the knob 19 via the connecting rod 18, rotates synchronously. A second valve seat 17 is provided on one side of the first valve seat 16. The second valve seat 17 is a foldable hemispherical structure. A fixing structure is provided on one side of the second valve seat 17. The upper and lower ends of the fixing structure are respectively fixedly connected to the inside of the fixing ring 15. At the same time, the side of the fixing structure away from the second valve seat 17 is movably connected to the first valve seat 16. The other side of the second valve seat 17 is fixedly connected to the other side of the first valve seat 16. As a result, when the knob 19 is rotated, the first valve seat 16 rotates synchronously, the second valve seat 17 folds, the internal space of the double connecting pipe 12 is opened, and gas enters the device.

[0037] Step two: The first protective shell 1 and the second protective shell 2 are securely connected by screws. The fastening ring 8 is fixed at the pipe opening formed by the tight connection of the first protective shell 1 and the second protective shell 2, ensuring the stability of the subsequent structure. The operation of the overall structure will not be affected by the movable connection between the fastening ring 8 and the first protective shell 1 and the second protective shell 2. Furthermore, because the fastening ring 8 has a telescopic rod 24 and a spring working together, the expansion ring 4 and the fastening ring 8 are fixedly connected by the fixing block 9, so that the device can adapt to a certain range of air pressure changes and prevent gas leakage caused by small changes in the internal air pressure of the device.

[0038] Step 3: When gas enters the section containing hose 3, due to the elastic structure of hose 3, the pressure detection ring 5 set on the outer periphery of hose 3 can detect the gas pressure inside hose 3 in real time. When gas leaks inside the device, the pressure detection ring 5 attached to the outer periphery of hose 3 can react and transmit the detected electrical signal to the display screen 6 in a timely manner. The display screen 6 ensures that the gas leak can be reacted to in a timely manner to avoid the occurrence of danger. Since the device has multiple flange structures, it is for the convenience of disassembling the device and maintaining the inside, but at the same time, it may cause the sealing to be inadequate. Therefore, a gas detection alarm 10 is fixedly installed at the flange connection. When a gas leak occurs at the connection, the gas detection alarm 10 can detect and alarm in a timely manner.

[0039] Step four: Finally, check the display screen 6 to ensure that the gas inside the device is within a safe pressure range. At this time, rotate the knob 19 in the opposite direction to close the internal space of the double connecting pipe 12, ensuring the overall sealing of the device. Set a base plate 22 at the bottom of the second protective shell 2, and fix multiple self-locking casters 23 at the bottom of the base plate 22 to facilitate the transportation and movement of the device.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
