Description

Technical Field

[0001] This utility model relates to the field of battery compartment equipment technology, specifically a quick-moving liquid-cooled battery energy storage compartment device. Background Technology

[0002] In well workover operations in the oilfield equipment sector, the power demand on-site fluctuates due to winch hoisting and lowering operations. To avoid grid tripping or generator shutdown, the power margin needs to be sufficiently large. This results in a large number of generator sets being configured, which typically operate in inefficient ranges, generating significant fuel consumption and additional emissions, greatly increasing the overall operating cost of the equipment. In addition, sudden increases and decreases in load have a significant impact on the power system. Diesel generators may not respond in time and are prone to incomplete combustion, leading to "grid frequency reduction" and "black smoke from diesel engines." This not only wastes a lot of fuel but also causes environmental pollution and damages electrical equipment. When the tubing string is lowered, a large amount of gravitational potential energy is generated, which is usually released as heat through energy-consuming braking, resulting in energy waste.

[0003] With the continuous development of energy storage technology, the safety, power density, and charge / discharge rate of energy storage systems have been greatly improved. The application of energy storage technology can solve the above problems to a certain extent. However, for the harsh environment of oil drilling and repair rig operation sites, especially high-temperature desert areas, conventional battery energy storage containers cannot yet adequately meet the requirements in terms of rapid transportation, temperature resistance, sand protection, and safety. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a fast-moving liquid-cooled battery energy storage chamber device, which solves the problems in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a fast-moving liquid-cooled battery energy storage compartment device, including a trailer, on which a water fire-fighting device and an energy storage container are installed. Underneath the trailer are a hydraulic station, an air suspension, and hydraulic outriggers respectively installed at the four corners of the trailer. Both sides of the trailer are hinged with walkways and rotating railings. The energy storage container contains a battery compartment, an electrical control compartment, and a transformer compartment in sequence. The battery compartment contains several battery clusters, a fire-fighting device, a liquid cooling unit, and a first air-cooled air conditioner. The electrical control compartment contains a combiner cabinet, a PCS cabinet, a switch cabinet, an EMS cabinet, a smoke detector, and a temperature and humidity sensor. The exterior of the battery compartment is equipped with an exhaust fan, a pressure relief port, and an air intake grille. The top of the electrical control compartment is equipped with a second air-cooled air conditioner. Both inner walls of the electrical control compartment are equipped with return air ducts. An interconnected air outlet duct is provided between the second air-cooled air conditioner and the electrical control compartment. The transformer compartment contains a transformer, a plug-in box, a temperature controller, and a temperature sensor.

[0006] As an optimization, the water fire-fighting device includes a water tank and a fire pump, and the battery compartment is equipped with a water fire-fighting pipeline connected to the fire pump.

[0007] As an optimization, the trailer is also equipped with a spare tire and an operating handle for controlling the hydraulic outriggers.

[0008] As an optimization, fireproof partitions are provided between the battery compartment and the electrical control compartment, as well as between the electrical control compartment and the transformer compartment.

[0009] As an optimization, a number of evenly distributed hinges are provided between the walkway and the trailer, and the rotating railing includes a number of evenly distributed rotating support frames supported under the walkway and hinged to the trailer, with railings connected to the outer ends of the rotating support frames.

[0010] As an optimization, the rotating support frame is provided with a socket, and the trailer is provided with a locking pin that mates with the socket.

[0011] As an optimization, the outer wall of the battery compartment is equipped with a manual alarm and a combustible gas detector alarm.

[0012] As an optimization, the transformer is a dry-type cast iron transformer.

[0013] As an optimization, the inner wall of the battery compartment is provided with an insulation layer.

[0014] As an optimization, the trailer is equipped with a towing pin and a towing bar at the front end.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a fast-moving liquid-cooled battery energy storage compartment device. A towing pin is installed at the gooseneck structure at the front of the trailer. After connecting and installing with the tractor unit through this structure, rapid movement over a wide area can be achieved. Trailer bars are installed at the front and rear of the trailer, allowing for auxiliary equipment to help it get out of trouble in special circumstances. The trailer's axles use air suspension, which can bear the weight of the trailer and all the equipment on board, and effectively filter vibrations from the road surface during equipment movement. The frame is designed and manufactured using high-strength structural materials and is equipped with a hydraulic station, hydraulic outriggers, and operating handles. Upon arrival at the work site, the hydraulic station can be activated, and the outrigger cylinder height can be adjusted using the operating handles to bring the trailer into working condition. The trailer walkway adopts a rotating and retractable type: during movement, the walkway steps can be folded upwards, and the railings can be quickly rotated and retracted for fixation. With these measures, the equipment can quickly reach the set location and quickly reach a working ready state, solving the problems of difficult movement and slow arrival speed of traditional solutions for this type of equipment.

[0016] The battery compartment houses energy storage battery packs, a battery management system, a cooling system, and gas fire suppression equipment. To regulate the operating temperature of the battery, the compartment walls are lined with a high-efficiency insulation layer and equipped with cooling equipment such as liquid coolers and air-cooled air conditioners. The liquid coolers drive coolant along pipelines into the battery pack to remove the heat generated by the cells in a timely manner; the air-cooled air conditioners can regulate the ambient temperature inside the compartment in a timely manner.

[0017] The cooling equipment (air-cooled air conditioners and liquid-cooled units) adopts a redundant configuration of one in use and one on standby, and has a special thermal management strategy to ensure that the energy storage battery is always in a suitable operating temperature environment:

[0018] 1) Cooling equipment (air-cooled air conditioners and liquid-cooled units) can all be started individually. When one of the devices fails, the other devices can still work independently to achieve the temperature regulation effect.

[0019] 2) Depending on the battery's operating conditions, the cooling equipment (air-cooled air conditioners and liquid-cooled units) can automatically select the number of devices to be started, ensuring effective temperature regulation and energy saving;

[0020] 3) Through algorithm adjustment, the flow rate of coolant in different areas of the battery pack can be controlled, and the cell temperature can be precisely adjusted;

[0021] The battery compartment employs a fire safety system that combines inert gas protection with passive fire prevention. This system considers all aspects of battery environmental safety, thermal runaway early warning, and battery pack fire suppression, ensuring that the battery pack's working environment is essentially under inert gas protection at all times. Through the effective combination of active protection and passive prevention measures, the long-term safe operation of the battery pack is guaranteed.

[0022] The electrical control compartment features a walk-in design for easy access for staff to perform operations and maintenance. It is equipped with a power storage converter (PCS), a DC-DC bidirectional converter, an energy management system (EMS), switchgear, smoke detectors, temperature and humidity sensors, and carbon dioxide fire extinguishers. The compartment utilizes two redundant air conditioning units mounted on top of the transformer compartment, one in operation and one on standby. These units can start independently to ensure the temperature and humidity within the compartment remain within acceptable limits, meeting the requirements for operation in the high-temperature desert environment. The transformer compartment employs a semi-open structure with rain protection to ensure effective heat dissipation. The transformer is a dry-type cast iron transformer with forced air cooling, equipped with a temperature controller and temperature sensors to automatically start and stop the cooling fans. A cable outlet box is located within the transformer compartment as the cable inlet and outlet, typically using enclosed connectors. The outlet box opening has a foldable cover for effective weather protection.

[0023] The water fire suppression system is interlocked with the fire suppression system of the energy storage container. In extreme cases such as thermal runaway of the energy storage battery or failure of the gas fire suppression system, it can be automatically activated to use water cooling and flooding to prevent greater losses.

[0024] Using this energy storage container, the power from different sources such as the on-site well site power grid, energy storage batteries and diesel generators can be effectively managed to jointly drive the operation of drilling and workover equipment. Potential energy can also be recovered during the operation of drilling and workover equipment. By effectively integrating power from different sources, this energy storage container can meet the energy demand under complex working conditions during drilling and workover, realize peak shaving and valley filling of well site energy, and greatly improve the overall energy utilization efficiency.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] For ease of description, the words "up," "down," "left," and "right" appearing in this utility model only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Combined with appendix Figure 1 This invention discloses a liquid-cooled battery energy storage device, which includes a water tank 1, a fire pump 2, an energy storage container, a hydraulic station 14, etc. All equipment is arranged on a trailer, which is equipped with an air suspension 16, which can effectively absorb and filter vibrations from the road surface during transportation, ensuring the safety of the above equipment.

[0037] The trailer is equipped with a spare tire 12, a rotating guardrail 11, hydraulic outriggers 13, and an operating handle 15. The trailer is pulled by a tractor and quickly arrives at the designated location on the work site. The hydraulic station 14 is then activated, and the working height of the trailer can be adjusted by using the operating handle 15 to adjust the height of the four hydraulic outriggers 13.

[0038] Combined with appendix Figure 2 Appendix Figure 3 The energy storage container is divided into battery compartment, electrical control compartment, and transformer compartment, with fireproof partitions separating the compartments. Different equipment is installed in each compartment. The battery compartment houses 17 battery clusters, totaling 5 clusters with a total capacity of approximately 317 kWh. The battery clusters are liquid-cooled, equipped with two liquid-cooled chiller units and two primary air-cooled air conditioners. The cooling capacity is redundantly designed to ensure that the temperature inside the battery compartment and battery clusters remains within a suitable range, and to ensure the system can continue operating even in special circumstances.

[0039] The battery compartment is equipped with a fire-fighting device 23. Exhaust fans 6, pressure relief vents 7, and air intake grilles are located at appropriate positions on the outer wall of the battery compartment to promptly expel flammable gases from the compartment. Smoke detectors 19, temperature and humidity sensors 22, and flammable gas detectors 9 are distributed in key locations. These fire-fighting sensors, along with manual alarms 8 and fire sprinklers, are linked for systematic protection of the safe operation of the batteries within the compartment. (See appendix) Figure 4 and appendix Figure 5 The electric energy storage container is equipped with a water fire-fighting pipeline 3, which is connected to the fire pump 2 pipeline. In extreme cases, the water fire-fighting system can be automatically activated to control the occurrence of accidents and avoid greater losses.

[0040] The electrical control compartment houses equipment such as a junction box 18, a PCS cabinet 20, a switch cabinet 24, and an EMS cabinet 25. A second air-cooled air conditioner 10 is installed on the top of the compartment. The electrical control cabinets feature a special air duct design for temperature control, which effectively distributes heat between the heat source (electrical control cabinets) and the operating space within the compartment. This ensures a temperature gradient match between the working space within the electrical cabinets and the personnel activity space within the electrical control compartment, resulting in energy savings and excellent cooling. (See attached...) Figure 4 The cold air generated by the second air-cooled air conditioner 10 enters the electrical control compartment through the air conditioner outlet duct 26, and then enters the electrical cabinet through the bottom of the electrical cabinet. After circulating in the cabinet, the cold air enters the air conditioner return duct 21 and finally returns to the air conditioner, completing the cycle. After this cycle, the temperature of the electrical control compartment environment can be effectively controlled, and the heat of the heating modules in the electrical cabinet can be removed in time to ensure the normal operation of the relevant components.

[0041] The transformer compartment houses transformers and plug-in boxes, allowing the grid power output interface and the power input interface of electrical equipment to be connected to the energy storage compartment plug-in boxes. Through the EMS system in the energy storage compartment, various modules at the well site can be effectively integrated, enabling three working modes: black start independent power supply, energy storage + grid, and energy storage + generator, achieving rapid response and timely switching between different modes.

[0042] Furthermore, in conjunction with the appendix Figure 5 After the equipment completes its work, the walkway railings and other structures can be quickly retracted, bringing the entire trailer module into transport mode and facilitating timely site relocation. At this point, the walkway 27 can be folded upwards, and the rotating support frame 28 can be rotated 90 degrees towards the rear of the vehicle. The folded walkway position can then be locked using railings, and the walkway, railings, and other structures can be secured using locking pins 29. Once the equipment arrives at the new site, the steps can be reversed to quickly unfold the walkway railings, bringing the entire module into working mode.

[0043] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any appropriate changes or modifications made by a person skilled in the art that conform to the claims of this utility model should fall within the patent protection scope of this utility model.
