Description

Technical Field

[0001] This utility model relates to the technical field of gas leak protection devices, and more specifically, to a gas equipment protection device. Background Technology

[0002] With the widespread use of natural gas in industrial production and daily life, the use of gas appliances is becoming increasingly common. However, natural gas is flammable and explosive. Once a leak occurs or an abnormal external condition occurs, it can easily lead to serious safety accidents, posing a huge threat to people's lives and property.

[0003] Currently, while some gas equipment on the market possesses certain protective measures, numerous shortcomings remain. Since gas equipment relies on pipelines for gas delivery, pipeline protection is crucial. However, most protective devices focus solely on detecting gas leaks, lacking effective protection against risks such as mechanical impacts that may occur during pipeline operation. For instance, in industrial production environments, gas pipelines may be accidentally struck by surrounding machinery, leading to equipment casing rupture, pipeline damage, and ultimately, gas leaks. Furthermore, the installation and maintenance of some protective devices are complex, requiring specialized technicians, which not only increases operating costs but also reduces their practicality and widespread adoption. Therefore, we propose a gas equipment protective device. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a gas equipment protection device, including a conveying pipeline 1, an electric valve 10 and a manual valve 11 fixedly installed on the conveying pipeline 1, the manual valve 11 being used for manual opening and closing operation; an anti-collision protection component 2 is provided on the exposed section of the conveying pipeline 1, so that the exposed part or the part that is easily hit by collision is physically protected during daily use, reducing the risk of gas leakage caused by pipeline damage due to collision;

[0030] Specifically, the anti-collision protection component 2 includes two symmetrical protective sleeves 20 that are fitted onto the conveying pipe 1. The two protective sleeves 20 are detachably connected. Multiple fixing protrusions 201 are fixedly installed on both the upper and lower sides of the protective sleeves 20. The two corresponding fixing protrusions 201 are fixedly connected by fastening screws, making the installation and disassembly of the anti-collision protection component 2 more convenient and facilitating the maintenance of the conveying pipe 1.

[0031] Specifically, the end of the protective sleeve 20 is provided with an arc-shaped hole 21, through which the conveying pipe 1 passes for normal arrangement and operation. The cross-section of the arc-shaped hole 21 is semi-circular, and a rubber pad 211 is fixedly installed on the hole wall of the arc-shaped hole 21. The rubber pad 211 fills the gap between the two, so that the protective sleeve 20 and the conveying pipe 1 are tightly connected, which can protect the pipe and prevent foreign objects from entering.

[0032] In this embodiment, a protective box 22 is fixedly installed on the protective sleeve 20. The electric valve 10 and the manual valve 11 are both located between the two protective boxes 22, so that the electric valve 10 and the manual valve 11 are covered in it, so that the electric valve 10 and the manual valve 11 are effectively protected and avoid being damaged by collisions and affecting their use.

[0033] Specifically, the protective box 22 located on the front side is provided with an exposure hole 23 that connects to the outside. The bottom wall of the exposure hole 23 is provided with a wiring hole 231 that connects to the outside. The exposure hole 23 provides space for operating the valve, and the wiring hole 231 facilitates the wiring to pass through, making the wiring connection of the electric valve 10 more convenient, while not affecting the protective function of the protective box 22 for the valve.

[0034] Furthermore, a door 24 is hinged to the front side of the protective box 22, allowing the door 24 to be opened or closed, enabling staff to easily operate and maintain the electric valve 10 and manual valve 11 inside the box; a door lock 241 is provided on the door 24, which enhances the security of the protection.

[0035] In addition, a detection component 4 is installed on one side of the conveying pipeline 1. The detection component 4 includes a gas sensor 42. A control host 3 is installed on one side of the conveying pipeline 1. A display screen 31 is installed on the front side of the control host 3. An alarm 32 is fixedly installed on the top surface of the control host 3. The detection component 4 monitors gas leaks. The control host 3 receives and processes the detection signals, so that gas leaks can be detected and dealt with in a timely manner, ensuring the safety of personnel and the environment. The display screen 31 displays equipment operation and detection information. The alarm 32 sounds an alarm when there is an abnormality, so that staff can intuitively understand the equipment status and deal with gas leaks and other problems in a timely manner.

[0036] It is worth noting that multiple fixing protrusions 30 are fixedly installed on both the left and right sides of the housing of the control host 3. The fixing protrusions 30 are fixedly installed on the external frame by fastening screws, so that the control host 3 is installed firmly and facilitates wiring and operation.

[0037] It is worth noting that the detection component 4 also includes a ventilation duct 40. The gas sensor 42 is fixedly installed on the ventilation duct 40 and inserted into the interior of the ventilation duct 40. A fan 43 is fixedly installed on the inner wall of the ventilation duct 40. The fan 43 accelerates the gas flow inside the ventilation duct 40, and the gas sensor 42 quickly detects the gas concentration, making the gas leak detection more timely and accurate. A mounting base 41 is fixedly installed on the outer surface of the ventilation duct 40. The mounting base 41 is fixedly installed on the external frame by multiple fastening screws, so that the detection component 4 is firmly installed and easy to monitor the surrounding gas.

[0038] In this embodiment, the detection component 4 is installed around the corresponding pipeline or gas-using equipment. The gas sensor 42 can detect whether there is a gas leak. The gas sensor 42 can use electrochemical sensing technology, which has the characteristics of fast response speed and high detection accuracy. Once a gas leak is detected, the gas sensor 42 will immediately transmit the signal to the control host 3. The control host 3 receives the signal from the gas sensor 42 and analyzes and processes the signal. When a gas leak is detected, the control host 3 will immediately activate the alarm 32 and issue an audible and visual alarm signal to remind people around to pay attention to safety. At the same time, the control host 3 will control the electric valve 10 to close, cut off the gas supply, and prevent the accident from escalating further.

[0039] Finally, it should be noted that the gas sensor 42, control host 3, alarm 32, electric valve 10 and fan 43 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0040] When using the gas equipment protection device of this utility model, firstly, put the two protective sleeves 20 on the corresponding exposed sections of the conveying pipe 1 and connect them by the fastening screws on the fixing protrusion 201. At this time, the electric valve 10 and the manual valve 11 are located between the protection box 22. The pipe passes through the arc-shaped hole 21 at the end of the protective sleeve 20, and the rubber pad 211 on the wall of the arc-shaped hole 21 fills the gap.

[0041] Next, connect the detection component 4 and the control host 3, install the ventilation duct 40 around the gas equipment through the fixing base 41, turn on the fan 43 and install the control host 3 on the external frame through the fixing protrusion 30;

[0042] During normal operation, staff can operate the manual valve 11 through the exposure hole 23 on the box door 24 as needed. The gas sensor 42 in the detection component 4 monitors the surrounding gas concentration in real time. Once the gas sensor 42 detects a gas leak, it will quickly transmit the signal to the control host 3. After analyzing the signal, the control host 3 will activate the alarm 32 to issue an audible and visual alarm, and at the same time control the electric valve 10 to close, cutting off the gas supply and preventing the accident from worsening. During this period, staff can monitor the equipment operation and detection status at any time through the display screen 31 of the control host 3.
