Description

Technical Field

[0001] This utility model relates to the field of fire protection technology for fracturing well sites, and more specifically, to a fire protection device and fracturing system for fracturing well sites. Background Technology

[0002] The fracturing well site requires a large number of fracturing equipment sets. During operation, these equipment components generate heat, leading to high temperatures. The internal components, including lubricating oil, cables, electrical components, frequency converters, and transformers, are prone to combustion under these high temperatures, potentially causing fires. Furthermore, the close proximity of equipment during fracturing well site operations means that a fire in one piece of equipment can easily ignite nearby equipment, resulting in a large-scale fire affecting multiple pieces of equipment, rendering the facilities inoperable, and causing significant construction and safety accidents. Currently, fires at fracturing well sites are primarily extinguished manually using fire extinguishers. However, manual firefighting is inefficient, and the high voltage, high pressure, and large displacement of equipment at fracturing well sites further increase the risk of fire.

[0034] This utility model embodiment provides a fire-fighting device for fracturing well sites, including a fire-fighting component 1 and a control component 2. The fire-fighting component 1 includes a storage container 11 and a spraying pipeline 12. The control component 2 includes a control device 21 and a detection element 22. The storage container 11 is connected to the spraying pipeline 12, which is used to connect to the components to be fire-fighted in the fracturing well site. The detection element 22 is disposed on the spraying pipeline 12 and / or the components to be fire-fighted. The detection element 22 is communicatively connected to the control device 21, which is also communicatively connected to the spraying pipeline 12 and / or the storage container 11.

[0035] Combination Figure 1As shown in the figure, some components in a fracturing well site are illustrated, such as the frequency converter drive component 100, the electric motor 200, the plunger pump 300, the support structure 400, the power supply equipment 500, and the power distribution equipment 600. Various components in the fracturing well site can be selected as fire-fighting components according to actual needs. The storage container 11 stores fire extinguishing agents, which can be selected as foam fire extinguishing agents, water-based fire extinguishing agents, carbon dioxide fire extinguishing agents, aerosols, etc., as needed. The spraying pipeline 12 can extend to connect with the corresponding fire-fighting components. The detection element 22 can be a fire-detecting component, such as a temperature sensor, smoke sensor, combustible gas sensor, or image recognition device (recognizing flame images, arc discharge images, smoke images, etc.). The detection element 22 can be set on the fire-fighting component to detect parameters such as temperature, or it can be set on the spraying pipeline 12 for monitoring (e.g., image recognition device), or the detection element 22 can be set on both the fire-fighting component and the spraying pipeline 12 to detect and obtain more parameters to determine whether a fire has occurred, which helps to improve the accuracy of the judgment. The detection element 22 and the control device 21 can be connected via cable, wireless network, or other means (in this embodiment, the communication connection is achieved via cable, i.e.) Figure 1 (The dashed curve in the image) transmits the information detected by the detection element 22 to the control device 21. The control device 21 can control the spraying pipeline 12 and / or the storage container 11 through, for example, electrical circuits, programs, etc.

[0036] In one embodiment, the control device 21 and the spraying pipeline 12 are connected via a cable. When the spraying pipeline 12 receives a corresponding signal, it controls the valve structure on the spraying pipeline 12 to perform corresponding actions to achieve the spraying of the extinguishing agent.

[0037] It is understood that the control device 21 can also be connected to the storage container 11 in communication, or simultaneously connected to the storage container 11 and the spraying pipeline 12, so as to control the spraying of the extinguishing agent (for example, by setting a valve structure at the outlet of the storage container 11 to realize the on-off control of the extinguishing agent). At the same time, communication can be achieved through cables, wireless networks, etc. as needed. The specific communication connection scheme is not limited here.

[0038] The fire-fighting device for fracturing well sites in this invention uses a detection element 22 installed on the spraying pipeline 12 and / or the component to be extinguished. The control device 21, which is communicatively connected to the detection element 22, can detect and judge the fire ignition phenomenon, thereby controlling the spraying pipeline 12 and / or the storage container 11. This allows the extinguishing agent in the storage container 11 to be sprayed through the spraying pipeline 12 onto the corresponding component to be extinguished, achieving automated fire extinguishing for the components to be extinguished in the fracturing well site. This device can extinguish fires on the components to be extinguished without relying on manual labor, improving fire extinguishing efficiency and reducing the risk of fire to on-site workers.

[0039] The first end of the spray pipe 12 is connected to the storage container 11. The second end of the spray pipe 12 can be exemplarily a pipe structure with thermal rupture characteristics (not shown in the figure). When the temperature reaches a certain value, the second end of the spray pipe 12 ruptures, causing a large amount of extinguishing agent to be sprayed out to extinguish the fire on the components to be extinguished.

[0040] It is understandable that when there are multiple fire-fighting components, the same or more sprinkler pipes 12 can be installed to better meet the fire-fighting needs of different locations.

[0041] Combination Figure 1 and Figure 2 As shown, the spraying pipeline 12 is equipped with a nozzle structure 121.

[0042] The nozzle structure 121 is installed on the spray pipe 12. The nozzle structure 121 can spray the extinguishing agent to the corresponding fire-fighting component, thereby improving the fire extinguishing effect.

[0043] Furthermore, the storage container 11 includes a first container 111, a second container 112, and a first pipeline 113. The first container 111 is connected to the spraying pipeline 12, and the second container 112 is connected to the first container 111 through the first pipeline 113. The second container 112 is used to store pressurized gas or pressurized liquid, and the first container 111 is used to store fire extinguishing agent.

[0044] Combination Figure 3 and Figure 4 As shown, the structure within the dashed box, namely the storage container 11, mainly consists of a first container 111, a second container 112, and a first pipeline 113. The second container 112 can store pressurized gas or pressurized liquid and has a certain pressure. The first container 111 can store fire extinguishing agent. The first container 111 and the second container 112 are connected through the first pipeline 113, so that the pressurized gas or pressurized liquid can be delivered to the first container 111 and delivered together with the fire extinguishing agent to the spraying pipeline 12, thereby realizing the delivery of the fire extinguishing agent.

[0045] In this way, the rapid delivery of extinguishing agents is achieved through pressurized gas or pressurized liquid, which helps to improve fire extinguishing efficiency.

[0046] Furthermore, at least one of the first pipeline 113, the first container 111, and the second container 112 is provided with a first valve 1131 to control the opening and closing of the first pipeline 113.

[0047] In this embodiment, combined with Figure 3 and Figure 4As shown, the first valve 1131 is installed on the first pipeline 113. The first valve 1131 can be a manual, automatic or manual-automatic integrated valve structure, which can control the opening and closing of the first pipeline 113, thereby controlling whether pressurized gas or pressurized liquid enters the first container 111, and realizing the pressurization control of the extinguishing agent.

[0048] It is understandable that the first valve 1131 can also be set on the first container 111 or the second container 112 (for example, at the port on the first container 111 that is connected to the first pipeline 113), as long as the first pipeline 113 can be opened and closed. The specific installation position of the first valve 1131 is not limited here.

[0049] Thus, the pressurization control of the extinguishing agent can be better achieved through the first valve 1131.

[0050] Preferably, the control device 21 is communicatively connected to the first valve 1131.

[0051] In this embodiment, combined with Figure 3 and Figure 4 As shown, the control device 21 is connected to the first valve 1131 via the cable shown by the dashed line. When the control device 21 detects a fire or an arc discharge through the detection element 22, the control device 21 sends a corresponding command through the cable to open the first valve 1131, allowing pressurized gas or pressurized liquid to enter the first container 111 and be pressurized.

[0052] In this way, a more automated pressurization process can be achieved by communicating with the first valve 1131 through the control device 21.

[0053] Furthermore, at least one of the first container 111 and the spraying pipeline 12 is provided with a second valve 122 to control the opening and closing of the spraying pipeline 12.

[0054] In this embodiment, combined with Figure 4 As shown, the second valve 122 is installed on the spraying pipeline 12, which can control the opening and closing of the spraying pipeline 12, thereby controlling the opening and closing of the fire extinguishing agent.

[0055] It is understandable that the second valve 122 can also be installed on the first container 111 or the nozzle structure 121, as long as it can control the on / off state of the spray pipeline 12. The second valve 122 can be a manual, automatic, or a combination of manual and automatic valve structures.

[0056] Thus, the on / off control of the spraying pipeline 12 is achieved through the second valve 122, thereby realizing the on / off control of the extinguishing agent.

[0057] Preferably, the control device 21 is communicatively connected to the second valve 122.

[0058] Combination Figure 4 As shown, the second valve 122 and the control device 21 are connected by a cable shown by a dashed line. When the control device 21 detects a fire or an arc discharge through the detection element 22, the control device 21 sends a corresponding command to the second valve 122 through the cable, causing the second valve 122 to open. The extinguishing agent can then enter the spray pipe 12 and reach the corresponding fire-fighting component.

[0059] Thus, by communicating with the second valve 122 through the control device 21, a more automated fire extinguishing process can be achieved, which is beneficial to improving fire extinguishing efficiency.

[0060] This utility model also provides a fracturing system, including a component to be fire-fighted and the aforementioned fracturing well site fire-fighting device, wherein the spray pipe 12 of the fracturing well site fire-fighting device extends to connect with the component to be fire-fighted.

[0061] Combination Figure 1 As shown, the fracturing system includes components to be extinguished and the aforementioned fracturing well site fire-fighting device. The components to be extinguished can be selected as needed. The spraying pipeline 12 extends to connect with the corresponding components to be extinguished. The storage container 11 stores fire extinguishing agent. When the detection element 22 in the fracturing well site fire-fighting device detects a phenomenon related to fire, the control device 21 controls the spraying pipeline 12 and / or the storage container 11 to spray the fire extinguishing agent.

[0062] The fracturing system of this invention employs the aforementioned fire-fighting device for fracturing well sites. A detection element 22 is installed on the spraying pipeline 12 and / or the component to be extinguished. A control device 21, communicatively connected to the detection element 22, can detect and judge fire ignition phenomena, thereby controlling the spraying pipeline 12 and / or the storage container 11. This allows the extinguishing agent in the storage container 11 to be sprayed through the spraying pipeline 12 onto the corresponding component to be extinguished, achieving automated fire extinguishing of the component to be extinguished in the fracturing well site. This system can extinguish fires directly on the component to be extinguished without relying on manual labor, improving fire extinguishing efficiency and reducing the risk of fire to on-site workers.

[0063] Furthermore, the fire-fighting component includes at least one of a frequency converter drive component 100, a motor 200, and a plunger pump 300. The spraying pipeline 12 extends to be connected to the frequency converter drive component 100, the motor 200, and the plunger pump 300 respectively. The detection element 22 is respectively disposed in the frequency converter drive component 100, the motor 200, and the plunger pump 300.

[0064] Combination Figure 2As shown, the variable frequency drive unit 100 can drive the motor 200 and adjust its speed. The motor 200 can drive the plunger pump 300 to draw in or pressurize and discharge liquid. Additionally, the fracturing system may include other actuators such as centrifugal pumps, all of which can be driven by the motor 200. The plunger pump 300 is supplied with liquid through a surface high- and low-pressure manifold system. The plunger pump 300 pressurizes the liquid and delivers it underground to create fractures, thus achieving oil and gas production enhancement through fracturing.

[0065] Thus, the spray pipe 12 extends to connect to the frequency converter drive component 100, the electric motor 200, and the plunger pump 300 respectively, and plays an automatic fire extinguishing function for these high-temperature and flammable components.

[0066] Preferably, the component to be fire-fighted further includes a support structure 400, and the frequency converter drive component 100, the electric motor 200, and the plunger pump 300 are all installed on the support structure 400.

[0067] Optionally, the control device 21 and the storage container 11 are mounted on the support structure 400. Figure 5 As shown, this can improve the integration of the entire fracturing system.

[0068] Understandably, in combination Figures 6 to 8 As shown, multiple storage containers 11 can be provided, each connected to a component to be extinguished via a spray pipe 12. Considering different fire scenarios, different extinguishing agents (e.g., foam extinguishing agent, water-based extinguishing agent, carbon dioxide extinguishing agent, aerosol, etc.) can be used for different components. Multiple control devices 21 can also be provided, each communicating with a detection element 22. Each detection element 22 is correspondingly installed on each component to be extinguished, independently controlling the extinguishing process of each component. Combined with... Figure 9 As shown, the control device 21 consists of a fracturing control device 212 and a fire control device 211, independently controlling the fracturing and fire extinguishing processes; alternatively, the fracturing control device 212 and the fire control device 211 can be integrated into one unit; furthermore, in conjunction with Figure 11 As shown, the detection element 22 on each plunger pump 300, each motor 200, and each frequency converter drive component 100 is connected to a control device 21 to achieve centralized control; combined with Figure 10 As shown, for the plunger pump 300, motor 200 and frequency converter drive component 100 on the same support structure 400, their detection element 22 is first connected to the integrated device 213, and then the integrated device 213 on each support structure 400 is connected to a control device 21 for communication to achieve centralized control.

[0069] In other words, the control device 21 in this embodiment can be integrated with the control devices of various components in the fracturing system or can be separated.

[0070] Furthermore, the component to be fire-fighted includes at least one of a power supply device 500 and a power distribution device 600, the spray pipe 12 extends to be connected to the power supply device 500 and the power distribution device 600 respectively, and the detection element 22 is respectively disposed in the power supply device 500 and the power distribution device 600.

[0071] Combination Figure 1 As shown, the power supply equipment 500 and the power distribution equipment 600 are also components in the fracturing system that pose a fire risk. The fire extinguishing function is achieved by extending the spray pipe 12 to connect with the power supply equipment 500 and the power distribution equipment 600 respectively, and the fire detection function is achieved by the detection element 22, thus realizing an automated fire extinguishing process.
