[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] Unless otherwise defined, all the technical and scientific terms used in this document have the same meaning as understood by the person skilled in the art belonging to the technical field of the utility model.

[0028] Referring to Figure 1 , the utility model discloses an intelligent fire extinguishing device of oil and gas gathering and transportation system, in one of the embodiments, comprising:

[0029] Fire extinguishing agent tank body 01 is used for containing fire extinguishing agent. Specifically, the fire extinguishing agent can be water extinguishing agent, dry powder extinguishing agent, foam extinguishing agent, carbon dioxide extinguishing agent, halogenated alkane extinguishing agent and the like, and the embodiment is not limited.

[0030] The oil and gas gathering and transportation system refers to the system for collecting and transporting crude oil, natural gas, liquefied petroleum gas or natural gasoline extracted from an oil field, and the intelligent fire extinguishing device of the oil and gas gathering and transportation system is an intelligent fire extinguishing device applied to any one of the gathering and transportation systems of crude oil, natural gas, liquefied petroleum gas or natural gasoline.

[0031] The fire extinguishing agent conveying pipeline comprises a main pipeline 02 and a pipeline branch 03, one end of the main pipeline 02 is connected to the fire extinguishing agent tank 01, one end is arranged above the oil pump unit 100 and extends along the arrangement direction of the oil pump unit 100, the pipeline branch 03 of the main pipeline 02 is arranged in parallel to the body direction of the oil pump unit 100 above each oil pump unit 100 through an electric valve, and a fire extinguishing agent nozzle 04 is arranged on each pipeline branch 03 towards the corresponding oil pump unit.

[0032] Specifically, the fire extinguishing mechanism of the intelligent fire extinguishing device of the oil and gas gathering and transferring system comprises a water inlet type and a water-free type, wherein Figure 1 The structure diagram of the water-free type is shown in the figure, Figure 2 The structure diagram of the water inlet type is shown in the figure.

[0033] The fire extinguishing agent of the water-free type is provided by a fire extinguishing agent tank, which can be a foam fire extinguishing agent in particular, the intelligent fire extinguishing device of the water inlet type further comprises a water inlet pipeline 05, the water inlet of the water inlet pipeline 05 is used to access a fire-fighting water source, the water outlet of the water inlet pipeline 05 is arranged above the oil pump unit 100 and extends along the arrangement direction of the oil pump unit 100 to form the main pipeline 02 of the fire extinguishing agent conveying pipeline, the fire extinguishing agent tank 01 is connected to the main pipeline 02 through a valve 06 and a capillary pipeline 07, so as to realize mixing of the fire extinguishing agent in the fire extinguishing agent tank 01 with water to form a mixed fire extinguishing agent, and then conveying the mixed fire extinguishing agent to each oil pump unit 100 along the main pipeline 02 and the pipeline branch 03.

[0034] The two different fire extinguishing agent mechanisms can be applied to different application occasions, thereby enhancing the practicability of the intelligent fire extinguishing device of the oil and gas gathering and transferring system.

[0035] A plurality of groups of flame detection sensors 08 are arranged on each pipeline branch 03 and used to monitor the fire of the corresponding oil pump unit 100.

[0036] A controller is connected to the electric valve of the main pipeline 02, the electric valve of each pipeline branch 03 and each group of flame detection sensors 08 respectively, and used to control the electric valve of the main pipeline 02 and the electric valve of the corresponding pipeline branch 03 to open according to the fire detection signal detected by each group of flame detection sensors 08, so as to individually extinguish the fire of the oil pump unit 100.

[0037] Specifically, the electric valve of the main pipeline is an electric butterfly valve, the electric valve of the pipeline branch is an electric ball valve, and the electric butterfly valve and the electric ball valve can both control the opening degree of the valve through an electric signal.

[0038] The intelligent fire extinguishing device of the embodiment is based on a fire extinguishing agent tank to construct an automatic fire extinguishing mechanism. In specific applications, the number, size and capacity of the fire extinguishing agent tank can be set according to the actual needs of the oil pump house, fully meeting the metering needs of fire extinguishing materials in actual fire extinguishing scenarios, achieving effective fire extinguishing. Compared with the trigger mechanism of the suspended dry powder fire extinguisher, the fire extinguishing agent tank has a larger capacity and is more convenient to replenish, and effective fire extinguishing can be achieved.

[0039] The intelligent fire extinguishing device sets a pipeline branch on the main pipeline, sets a flame detection sensor and an electric valve on each pipeline branch and connects them to the controller, so that each pipeline branch can be controlled individually. One fire extinguishing agent tank can monitor the fire of a group of oil pump units and perform individual fire extinguishing treatment. The fire monitoring is accurate and controllable, the response speed is fast, and the oil pump can be quickly and effectively extinguished at the initial stage of the fire, preventing accidents. At the same time, targeted delivery and unified management of the fire extinguishing agent improve the effective utilization rate of the fire extinguishing agent and save material resources.

[0040] In one embodiment, the controller is also used to cut off the power supply of the oil pump unit 100 where the fire occurs, and the oil pump unit stops working. When a fire occurs, cutting off the power supply of the oil pump unit in time can effectively protect the oil pump unit from further damage, improve the safety performance of the oil pump unit, and prevent larger fire accidents.

[0041] In one embodiment, the controller includes a total controller 09 and a plurality of branch sub-controllers 10. The total controller 09 is arranged at one end of the fire extinguishing agent tank body 01, and each branch sub-controller 10 is arranged on one pipeline branch 03. One end of each branch sub-controller 10 is connected to a group of flame detection sensors 08 and electric valves on the corresponding pipeline branch 03, and the other end is connected to the total controller 09. Each branch sub-controller 10 is used to receive the detection signal of the flame detection sensor 08 on the corresponding pipeline branch 03 and send the detection signal to the total controller 09. Specifically, when a fire occurs, the total controller 09 cuts off the power supply of the oil pump unit 100 where the fire occurs.

[0042] Referring to Figure 3In one embodiment, the pipeline branch 03 includes a main pipeline connection section 031 and a pipeline branch section 032. The main pipeline connection section 031 is connected to the pipeline branch section 032. The main pipeline connection section 031 is used to fix the pipeline branch 03 on the main pipeline 02. Each branch controller 10 is respectively installed on the main pipeline connection section 031 of the pipeline branch 03. The electric valve 11 of the pipeline branch 03, specifically an electric ball valve, a flame detection sensor 08, and a fire extinguishing agent nozzle 04 are installed on the pipeline branch section 032. The electric ball valve is installed at the inlet of the pipeline branch section 032. The electric ball valve and the flame detection sensor 08 of the pipeline branch 03 are electrically connected to the corresponding branch controller 10.

[0043] See Figure 4 , Figure 4 This is a circuit diagram of an intelligent fire extinguishing device for an oil and gas gathering and transportation system, illustrating the intelligent control process of the device. After the flame detection sensor 08 on each pipeline branch 03 detects a fire in the oil pump unit 100 below, it sends the fire information to the branch controller 10 on that branch 03. The branch controller 10 then sends the fire information from each oil pump unit 100 to the main controller 09. The main controller 09 intelligently identifies the fire information from each oil pump unit 100 to determine if a fire has occurred. If a fire has occurred, the main controller 09 opens the electric butterfly valve on the main pipeline and issues a fire extinguishing command to the corresponding branch controller 10. Upon receiving the command, the branch controller 10 opens the electric ball valve on the pipeline branch 03, allowing the fire extinguishing agent nozzle to spray fire extinguishing agent directly below the oil pump unit 100, thus providing individual and centralized fire extinguishing for the affected oil pump unit 100.

[0044] Specifically, each set of flame detection sensors 08 includes a smoke sensor 081, a flame sensor 082, and a temperature transmitter sensor 083. Each set of flame detection sensors 08 is arranged along the body direction of the oil pump unit on a pipeline branch 03 and is connected to the branch controller 10 to monitor the fire situation of the corresponding oil pump unit 100.

[0045] Furthermore, the type of each set of flame detection sensors 08 is not limited to the three types mentioned above. After each set of flame detection sensors 08 detects the fire information of the corresponding oil pump unit, it sends the information to the main controller 09 via the branch controller 10. The main controller 09 can use AI technology to perform intelligent smoke recognition, intelligent flame recognition, and temperature anomaly recognition based on the acquired fire information to determine whether a fire has occurred. Once a fire is confirmed in one or more oil pump units, the main controller 09 enters the fire extinguishing procedure, opening the electric butterfly valve of the main pipeline 02 and the electric ball valve of the corresponding branch pipeline 03, and opening the extinguishing agent channel for fire extinguishing. This can extinguish the fire in its early stages, such as during the high-temperature or smoke-filled phase, before it develops into a large fire, effectively preventing major fires in the oil pump room and reducing the occurrence of fire accidents in the oil and gas gathering and transportation system.

[0046] In one embodiment, each pipeline branch 03 is further equipped with a branch pressure transmitter 19, which is connected to the branch controller 10 of its respective pipeline branch 03 to monitor the flow rate of the extinguishing agent in the corresponding pipeline branch. If the flow rate of the extinguishing agent in the pipeline branch 03 is detected to be too low, it indicates that there is too little extinguishing agent in the pipeline branch 03. This information is sent to the branch controller 10, which can increase the flow rate of the extinguishing agent by increasing the opening degree of the electric ball valve of that pipeline branch, thus ensuring the effectiveness of fire extinguishing.

[0047] In one embodiment, the intelligent fire extinguishing device of the oil and gas gathering and transportation system also includes a base 13, the fire extinguishing agent tank 01 is fixedly installed on the base 13, and a pressure level transmitter 14 is installed below the fire extinguishing agent tank 01. The pressure level transmitter 14 is connected to the main controller 09 and is used to monitor the real-time level of the fire extinguishing agent in the fire extinguishing agent tank 01.

[0048] If the main controller 09 detects that the extinguishing agent level in the extinguishing agent tank has dropped to a certain value, it can indicate that the extinguishing agent capacity in the tank is insufficient, reminding staff to add extinguishing agent to ensure sufficient extinguishing agent material.

[0049] In one embodiment, a booster pump 15 and a main pipeline pressure transmitter 16 are also installed on the main pipeline 02. Specifically, the electric valve 12 of the main pipeline 02, which is an electric butterfly valve, the booster pump 15, and the main pipeline pressure transmitter 16 are sequentially arranged and connected to the main controller 09. The booster pump 15 is used to pressurize the extinguishing agent output from the extinguishing agent tank 01, and the main pipeline pressure transmitter 16 is used to monitor the flow rate of the pressurized extinguishing agent. When the main controller 09 detects that the flow rate of the extinguishing agent in the main pipeline is too high, it can reduce the flow rate of the extinguishing agent by decreasing the opening of the electric butterfly valve on the main pipeline, thus rationally utilizing the extinguishing agent resources without affecting the fire extinguishing effect.

[0050] In one embodiment, the intelligent fire extinguishing device of the oil and gas gathering and transportation system also includes an alarm indicator light 17, which is installed at the end of the extinguishing agent tank 01 and connected to the main controller 09. This light illuminates when the main controller 09 detects a fire in the oil pump unit 100. Specifically, two indicator lights, red and green, can be set. When the main controller 09 detects a fire, the red light illuminates to alert personnel to take action.

[0051] In one embodiment, each oil pump unit 100 is equipped with a vibration sensor 18 on its motor. The vibration sensor 18 is connected to the corresponding branch controller 10. When abnormal motor vibration is detected, the branch controller 10 sends an abnormal signal to the main controller 09. The main controller 09 cuts off the power supply to the corresponding oil pump unit 100, and the oil pump unit 100 stops working.

[0052] When abnormal vibration of the motor in the oil pump unit 100 occurs, it indicates a malfunction in the oil pump unit. The vibration sensor 18 feeds back the abnormal information to the corresponding branch controller 10, which then sends it to the main controller 09. The main controller 09 then cuts off the power supply to the corresponding oil pump unit 100, preventing further damage to the oil pump unit due to the malfunction and improving its safety performance. Abnormal vibration of the motor in the oil pump unit 100 includes malfunctions caused by a fire or other abnormalities.

[0053] See Figure 5 Taking the intelligent control process of one of the pipeline branches as an example, the smoke sensor 081, flame sensor 082, and temperature transmitter sensor 083 on the pipeline branch 03 monitor the smoke, flame, and temperature signals of the oil pump unit located directly below the pipeline branch in real time, and send these fire detection signals to the branch sub-controller 10 of the pipeline branch. The branch sub-controller 10 sends these fire detection signals to the main controller 09. The main controller performs intelligent analysis on these fire detection signals to determine the fire situation of the target oil pump unit. When it is determined that the target oil pump unit is on fire, the main controller controls the electric butterfly valve of the main pipeline and the electric ball valve of the pipeline branch to open, and the fire extinguishing agent is sprayed out from the fire extinguishing agent nozzle 04 of the pipeline branch to extinguish the fire.

[0054] The main controller 09 monitors the extinguishing agent volume (01) in the fire extinguisher tank via the pressure and level transmitter 14, promptly reminding personnel to refill the tank to ensure an adequate supply of extinguishing material. Simultaneously, it monitors the flow rate of the extinguishing agent in the main pipeline via the main pipeline pressure transmitter 15 and regulates the flow rate by adjusting the opening of the main pipeline electric butterfly valve. The branch controller 10 monitors the flow rate of the extinguishing agent in the branch pipeline (03) via the branch pressure transmitter 19 and regulates the flow rate by adjusting the opening of the branch pipeline electric ball valve, thereby controlling the flow rate of the extinguishing agent in branch pipeline (03) within a reasonable range to ensure that the spray force of the extinguishing agent at the nozzle can achieve effective fire extinguishing.

[0055] The intelligent fire extinguishing device for the oil and gas gathering and transportation system in this application embodiment achieves centralized fire management of multiple oil pump units by constructing a main pipeline and pipeline branches. Fire extinguishing materials are uniformly provided by fire extinguishing agent tanks. By setting up a main controller and pipeline branch sub-controllers, each oil pump unit can be individually monitored and extinguished. The fire monitoring is accurate and controllable, the material utilization rate is high, and the response speed is fast. It can quickly and effectively extinguish the oil pumps in the early stage of a fire, effectively preventing the occurrence of fires in the oil and gas gathering and transportation system.

[0056] See Figure 5 This application also proposes an intelligent fire extinguishing system for an oil and gas gathering and transportation system, including the intelligent fire extinguishing device for an oil and gas gathering and transportation system as described in any of the above embodiments, and a monitoring terminal 20. The monitoring terminal 20 is connected to the controller, specifically the main controller 09, and receives the fire information of each oil pump unit 100 sent by the main controller 09 and displays it in a layout.

[0057] Specifically, the monitoring terminal 20 can be a monitoring platform, a personal computer or mobile terminal of the monitoring personnel, or other monitoring equipment. The fire information of each group of oil pump units 100 is arranged and displayed on the monitoring terminal 20, which allows for intuitive viewing of the fire detection information of each oil pump unit 100 in each group of oil pump units in the oil and gas gathering and transportation system, timely detection of abnormalities, and reduction of the occurrence of fires.

[0058] Furthermore, the monitoring terminal 20 is also equipped with a control menu, which allows monitoring personnel to remotely and manually control each oil pump unit. When manual intervention is required, monitoring personnel can issue relevant commands to the main controller through the control menu on the monitoring terminal interface to control the fire management process.

[0059] In one embodiment, the monitoring terminal 20 includes a display 21 and a manual control keyboard 22, and the monitoring personnel can also intervene in the fire management process by inputting control commands through the manual control keyboard.

[0060] Furthermore, the monitoring terminal 20 is also equipped with an audible and visual alarm 23. When the main controller 09 detects a fire, the monitoring terminal 20 receives the fire information sent by the main controller 09 via a data cable or wireless transmission, and activates the audible and visual alarm to remind the monitoring personnel to pay attention and handle the situation in a timely manner, thereby ensuring that the fire is handled promptly and effectively.
