Description

TECHNICAL FIELD

[0001] The present application relates to the field of pump stations, in particular to an emergency pump station for hydraulic hoist. BACKGROUND

[0002] The emergency pump station for hydraulic hoist is a key equipment in the fields of water conservancy projects and gate control, and its core function is to provide a reliable power source in emergency situations to ensure the normal operation of the equipment. Traditional emergency pump stations usually adopt a single energy source design, such as diesel engines or gasoline engines as power generation devices. This design has certain practicality in past applications and can meet basic emergency needs. However, with the increasing demand for equipment automation, intelligence, and response speed, the limitations of traditional emergency pump stations have gradually emerged.

[0003] Firstly, the reaction speed of traditional emergency pump stations is slow, which cannot meet the demand of modern engineering for fast response. Since diesel engines or gasoline engines need a certain time to warm up and run during the starting process, there is a significant delay between receiving the emergency signal and actually outputting power. This delay may cause serious consequences in emergency situations, such as the failure of the gate to close in time causing flooding, or the failure of the equipment to be repaired in time causing greater losses. Secondly, the operation of traditional emergency pump stations relies on manual intervention, and the degree of automation is low. In actual application, the operator needs to manually start the equipment and perform a series of complex operation steps, which not only increases the risk of human error, but also reduces the efficiency of emergency response. In addition, diesel engines or gasoline engines need regular maintenance to ensure their normal operation. This regular maintenance not only increases operating costs, but also may cause the equipment to fail to work properly at critical moments due to improper maintenance.

[0004] The main reason for these deficiencies is that the design concept and technology level of traditional emergency pump stations have not kept up with the development of modern engineering needs. The single energy source design, although simple, lacks redundancy and flexibility and cannot cope with complex emergency scenarios. At the same time, the degree of automation of traditional equipment is low, and modern control technology and intelligent means are not fully utilized, resulting in low operation efficiency. In addition, diesel engines or gasoline engines as power sources, their inherent mechanical properties and energy consumption patterns also limit the performance improvement of the equipment. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to at least overcome one deficiency of the prior art, and to provide an emergency pump station for hydraulic hoist, which uses solar energy and wind power dual input, and is provided with two independent energy storage packs to realize unmanned, long-term, reliable, and stable emergency opening and closing use.

[0006] To achieve the above object, the application relates to an emergency pump station of a hydraulic hoist, aiming to solve the technical problems of single energy, slow response speed, dependence on manual operation and high maintenance cost of the traditional emergency pump station. The emergency pump station system comprises an oil pump, a first motor, a second motor, a first energy storage cabinet, a second energy storage cabinet, a solar panel, a wind power assembly and a controller. Through the technical means of multi-energy collaborative power supply, dual-motor redundant drive, intelligent control and remote monitoring, the reliability, response speed and automation level of the equipment are significantly improved.

[0007] The input shaft of the oil pump is connected to the first motor and the second motor through a speed reducer, forming a dual-motor parallel drive structure. The first motor and the second motor are electrically connected to the controller and are uniformly controlled by the controller. The controller is connected to the first energy storage cabinet and the second energy storage cabinet through power lines, and is connected to the solar panel and the wind power assembly respectively. The controller can intelligently dispatch the electric energy generated by the solar panel and the wind power assembly according to the real-time energy supply situation, and preferentially charges the first energy storage cabinet and the second energy storage cabinet to ensure that the energy storage system is always in the best working state. In an emergency, the controller can selectively control the first energy storage cabinet or the second energy storage cabinet to discharge according to the load demand, drive the first motor or the second motor to work, thereby providing stable and reliable power output for the oil pump. The design of multi-energy collaborative power supply and dual-motor redundant drive not only improves the energy utilization efficiency of the system, but also enhances the emergency response capability and operation reliability of the equipment.

[0008] Further, the controller integrates at least one wireless communication module supporting multiple wireless communication protocols (such as Wi-Fi, 4G / 5G, LoRa, etc.) for realizing remote monitoring and wireless control. Through the wireless communication module, the operator can remotely access the controller, real-time access the device running state, energy supply situation and fault alarm information, and can remotely send control instructions to realize intelligent management of the emergency pump station. The introduction of wireless communication technology significantly reduces the frequency of manual intervention, improves the convenience of operation and the safety of the system.

[0009] In addition, the controller further comprises a wheel speed sensor installed on the output shaft of the oil pump for real-time monitoring of the rotational speed and rotation state of the output shaft of the oil pump. The wheel speed sensor transmits the collected rotational speed signal to the controller, and the controller can accurately judge the working state of the oil pump by analyzing the rotational speed data, timely find abnormal conditions (such as rotational speed fluctuation, jamming, etc.), and trigger the corresponding protection mechanism or alarm prompt. This real-time monitoring technology based on the wheel speed sensor further improves the intelligent level and fault diagnosis capability of the system.

[0010] To achieve comprehensive monitoring of the emergency pump station operating state, the controller is also connected with at least one high-definition monitoring camera. The monitoring camera is deployed at key positions of the emergency pump station, can collect equipment operating environment, mechanical component state and surrounding environment information in real time, and transmit video data to the controller through wired or wireless mode. The controller can automatically identify equipment abnormalities (such as leakage, overheating, foreign matter intrusion, etc.) through image recognition and analysis technology, and generate early warning information or trigger emergency response mechanism. This intelligent management scheme based on video monitoring not only improves the maintainability and safety of the equipment, but also provides reliable data support for fault diagnosis and accident analysis.

[0011] The hydraulic hoist emergency pump station of the present application realizes efficient, intelligent and reliable operation of the equipment through multiple energy collaborative power supply, dual motor redundant drive, wireless communication control, real-time wheel speed monitoring and video intelligent monitoring and other technical means. This technical scheme not only effectively solves the technical bottlenecks of single energy, slow response speed and dependence on manual operation of traditional emergency pump stations, but also provides an advanced emergency power solution for water conservancy projects, gate control and other fields, which has significant economic benefits and social value. At the same time, the modular design and intelligent management function of the system provide convenience for subsequent technical upgrading and expansion, and have wide application prospect.

[0022] The first energy storage cabinet 4 and the second energy storage cabinet 5 adopt modular design, composed of multiple lithium ion battery monomers in series inside, connected by nickel sheet welding between battery monomers to ensure the reliability of current transmission. The shell of the energy storage cabinet is made of aluminum alloy material, with cooling fans and temperature sensors inside for real-time monitoring of battery temperature and cooling control. The positive and negative output poles of the energy storage cabinet are connected to the controller 8 through copper bars, with silver plating treatment on the surface of the copper bars to reduce contact resistance and heat generation. The chemical formula of the battery monomer, the specific model of the cooling fan, and other details not disclosed belong to the known technology or existing technology of those skilled in the art, and do not need to be described in detail.

[0023] The solar panel 6 adopts monocrystalline silicon photovoltaic components, with an anti-reflection coating on the surface to improve the photoelectric conversion efficiency. The support of the solar panel 6 is made of stainless steel material, fixed on the ground by anchor bolts to ensure its stability and wind resistance.

[0024] The wind power generation component 7 adopts a vertical axis wind turbine, with carbon fiber composite material for the blades, having high strength and corrosion resistance. The base of the wind turbine is fixed on the concrete foundation by bolts to ensure its stability under strong wind conditions. The output ends of the solar panel 6 and the wind power generation component 7 are connected to the controller 8 through cables, with flame-retardant sheath to ensure safety in harsh environments. The specific composition of the anti-reflection coating, the proportioning of the carbon fiber composite material, and other details not disclosed belong to the known technology or existing technology of those skilled in the art, and do not need to be described in detail.

[0025] The controller 8 as the core control unit of the system, its hardware design includes main control chip, power module, voltage detection circuit, charge and discharge control circuit, voltage stabilizing circuit, communication module, sensor interface and drive circuit and other parts, through the design of highly integrated, realize the multi-energy collaborative control, equipment state monitoring and intelligent management.

The main control chip is connected with peripheral circuit through SPI, I2C, UART and other interfaces, realizes the fast transmission and processing of data. The power module adopts the design of wide input range switching power supply, the input voltage range is DC 9V-36V, can adapt to the voltage fluctuation of solar panel 6, wind power generation assembly 7 and energy storage cabinet output. The output of power module includes 5V and 3.3V two-way stabilized power supply, respectively for main control chip, communication module and sensor interface power supply, ensure the stable operation of each part of controller 8. The specific circuit design of switching power supply, the specific parameters of voltage stabilizing circuit and other contents not disclosed in detail belong to the known technology or prior art of those skilled in the art, and do not need to be described in detail.

[0026] The voltage detection circuit is used for real-time monitoring of the voltage state of the solar panel 6, the wind power generation assembly 7 and the energy storage cabinet. The voltage detection circuit uses a high-precision resistance divider network and a 16-bit analog-to-digital converter (ADC) to scale down the input voltage and convert it to a digital signal for processing by the main control chip. The main control chip obtains real-time voltage data of each energy module through the voltage detection circuit, and judges its working state according to the preset threshold value, such as whether the output voltage of the solar panel 6 reaches the maximum power point (MPPT), whether the voltage of the energy storage cabinet is within the safe range, etc. The charge and discharge control circuit is used to manage the charging and discharging process of the first and second energy storage cabinets 4 and 5. The charge and discharge control circuit includes MOSFET switch tube, drive chip and protection circuit. The MOSFET switch tube uses low on-resistance (Rds(on)) design, which can withstand large current and control its on-off state through PWM signal. The drive chip is used to provide sufficient drive current to ensure the fast response of the MOSFET switch tube. The protection circuit includes overcurrent protection, overvoltage protection and temperature protection, which can cut off the charge and discharge circuit in abnormal conditions to avoid equipment damage. The main control chip realizes intelligent charge and discharge management of the energy storage cabinet through the charge and discharge control circuit, such as charging the energy storage cabinet preferentially when the solar panel 6 or wind power generation assembly 7 outputs power; in emergency situations, the energy storage cabinet is discharged according to the load demand to drive the first motor 2 or the second motor 3 to work. The generation algorithm of PWM signal and the determination of protection threshold value are not disclosed in detail, which belong to the known technology or prior art of those skilled in the art, and do not need to be described in detail.

[0027] The voltage stabilizing circuit is used to provide stable operating voltage for the sensitive components inside the controller 8. The voltage stabilizing circuit includes a linear voltage regulator and a DC-DC step-down module. The linear voltage regulator adopts a low dropout (LDO) design, which can convert a 5V power supply to 3.3V to power the main control chip and communication module. The DC-DC step-down module uses synchronous rectification technology, which can efficiently convert the input voltage to the required low voltage DC, such as converting 12V to 5V, to power the sensor interface and drive circuit. The design of the voltage stabilizing circuit ensures the stable operation of the controller 8 under input voltage fluctuations. The communication module includes a wireless communication module and a wired communication interface. The wireless communication module supports multiple communication protocols such as Wi-Fi, 4G / 5G, and LoRa, enabling remote monitoring and wireless control. The antenna of the wireless communication module is connected to the controller 8 through an SMA interface, ensuring the stability of signal transmission. The wired communication interface uses RS485 bus, supporting multi-point communication and long-distance transmission, for data exchange with external devices. The design of the communication module allows operators to remotely access the controller 8 through mobile terminals or computers, obtaining real-time device operation status, energy supply conditions, and fault alarm information, and remotely sending control instructions to achieve intelligent management of emergency pump stations. The specific implementation of the communication protocol, the specific model of the wireless communication module, and other undisclosed contents belong to the common technical knowledge or existing technology of those skilled in the art, and do not need to be described in detail.

[0028] In addition, the controller 8 is also provided with a voltage conversion circuit for outputting and driving the first motor 2 or the second motor 3 to work.

[0029] The sensor interface includes analog input and digital input, used to connect the wheel speed sensor and the monitoring camera. The analog input channel uses a high-precision operational amplifier, which can amplify and convert the analog signal output by the sensor into a digital signal for the main control chip to process. The digital input channel uses optical isolation technology, which can effectively suppress electromagnetic interference and ensure the reliability of signal transmission. The drive circuit uses MOSFET power devices, which can achieve precise control of the first motor 2 and the second motor 3. The design of the drive circuit allows the controller 8 to intelligently select the first motor 2 or the second motor 3 to work according to the load demand, or simultaneously drive the dual motors to meet the high-power output demand. The specific model of the operational amplifier, the specific design of the optical isolation circuit, and other undisclosed contents belong to the common technical knowledge or existing technology of those skilled in the art, and do not need to be described in detail.

[0030] In this embodiment, the double-motor parallel driving structure of the first motor 2 and the second motor 3 is mainly used to improve the redundancy, reliability and emergency response capability of the emergency pump station of the hydraulic opening and closing machine. In the application scenario of the emergency pump station, the reliability of the equipment is crucial. Once the single-motor driving system fails (such as motor damage, circuit failure, etc.), the entire system will be unable to work, which may cause serious consequences. For example, in water conservancy projects, if the gate cannot be closed due to motor failure, it may cause flooding; in ship equipment, if the emergency pump station cannot be started, it may endanger the safety of the ship. By setting up a double-motor parallel driving structure, when the first motor 2 cannot work, the second motor 3 can be started immediately to ensure that the system can still operate normally in an emergency, significantly improving the redundancy and reliability of the equipment. In high-load working conditions, a single motor may need to run at full load for a long time, which can easily cause the motor to overheat or wear out, reducing its service life. The double-motor parallel driving structure can share the load to two motors, reducing the working intensity of a single motor and prolonging the service life of the motor. For example, in low-load conditions, the controller 8 can choose to start only the first motor 2; in high-load conditions, the controller 8 can start the first motor 2 and the second motor 3 at the same time to share the power output, ensuring the efficient operation of the system. The double-motor design can improve the response speed and operating efficiency of the system. In emergency situations, the controller 8 can intelligently select to start the first motor 2 or the second motor 3, or start both motors at the same time to meet different power requirements. For example, in an emergency situation that requires rapid startup, the controller 8 can start both motors at the same time to provide more power output and ensure that the equipment responds quickly; in normal operation, the controller 8 can choose to start only one motor to reduce energy consumption.

[0031] The double-motor parallel driving structure is connected with the input shaft of the oil pump 1 through a speed reducer 9. The speed reducer 9 adopts a planetary gear transmission design, which can reduce the speed of the motor and increase the output torque, ensuring the stable operation of the oil pump 1 under high pressure working conditions. The first motor 2 and the second motor 3 are electrically connected with the controller 8 and are uniformly controlled by the controller 8. The controller 8 intelligently selects to start the first motor 2 or the second motor 3, or simultaneously starts the double motors by real-time monitoring the load demand of the oil pump 1 and the operating state of the motor. Under normal working conditions, the controller 8 selects to start the first motor 2 or the second motor 3 according to the load demand. For example, under low load conditions, the controller 8 starts the first motor 2 to drive the oil pump 1 to work through the speed reducer 9; under high load conditions, the controller 8 starts the second motor 3 to share the load with the first motor 2, ensuring the efficient operation of the system. When the first motor 2 fails to work, the controller 8 monitors the operating state of the motor in real time through the wheel speed sensor and the current detection circuit, and immediately starts the second motor 3 after discovering the abnormality, ensuring that the system can still operate normally in emergency situations. For example, in water conservancy projects, if the first motor 2 fails to start due to circuit failure, the controller 8 immediately starts the second motor 3 to drive the oil pump 1 to work through the speed reducer 9, ensuring that the gate is closed in time to prevent flooding. In emergency situations requiring rapid response, the controller 8 can simultaneously start the first motor 2 and the second motor 3 to provide greater power output, ensuring that the equipment responds quickly. For example, in ship equipment, if the main power system fails, the controller 8 simultaneously starts the double motors to drive the oil pump 1 to work through the speed reducer 9, ensuring the normal operation of the key equipment of the ship.

[0032] The charge-discharge control circuit is one of the core functional modules of the controller 8, responsible for managing the charge-discharge process of the first energy storage cabinet 4 and the second energy storage cabinet 5, ensuring the efficient and safe operation of the energy storage system. The design of the charge-discharge control circuit includes charge-discharge management strategy, hardware circuit implementation, and protection mechanism. The charge-discharge management strategy is based on multi-energy collaborative control and load demand optimization. The controller 8 monitors the voltage state of the solar panel 6, the wind power assembly 7, and the energy storage cabinet in real time through the voltage detection circuit, and determines the timing and method of charging and discharging according to the preset threshold and algorithm. For example, when the output voltage of the solar panel 6 or the wind power assembly 7 is higher than the current voltage of the energy storage cabinet, the controller 8 starts the charging process to store energy into the energy storage cabinet; when the emergency pump station needs to be started, the controller 8 starts the discharging process according to the load demand to drive the first motor 2 or the second motor 3 to work. The charge-discharge management strategy also includes priority setting, for example, when multiple energy modules are simultaneously powered, the solar panel 6's energy is used for charging first to maximize energy utilization efficiency.

[0033] The hardware implementation of the charge-discharge control circuit includes MOSFET switch tube, drive chip, current detection circuit and protection circuit. The MOSFET switch tube adopts low on-resistance (Rds(on)) design, can bear large current and control its on-off state through PWM signal. During the charging process, the controller 8 adjusts the on-time of the MOSFET switch tube through the PWM signal to control the size of the charging current, realizing constant current charging or constant voltage charging. For example, in the constant current charging stage, the controller 8 maintains the charging current at a set value until the voltage of the energy storage cabinet approaches the full power state; in the constant voltage charging stage, the controller 8 gradually reduces the charging current until the energy storage cabinet is fully charged. During the discharging process, the controller 8 adjusts the on-time of the MOSFET switch tube through the PWM signal to control the size of the discharging current to meet the load demand. For example, in the case of low load, the controller 8 reduces the discharging current to prolong the use time of the energy storage cabinet; in the case of high load, the controller 8 increases the discharging current to ensure the normal operation of the emergency pump station.

[0034] The current detection circuit is used to monitor the size of the charging and discharging current in real time to ensure that it is within the safe range. The current detection circuit adopts high-precision Hall current sensor, which can convert the charging and discharging current into voltage signal for the main control chip to process. The main control chip obtains real-time current data through the current detection circuit, and judges whether the charging and discharging process is normal according to the preset threshold value. For example, when the charging current exceeds the set value, the controller 8 reduces the duty cycle of the PWM signal to reduce the charging current; when the discharging current exceeds the set value, the controller 8 increases the duty cycle of the PWM signal to increase the discharging current. The protection circuit is an important part of the charge-discharge control circuit, which is used to cut off the charging and discharging circuit in time in abnormal conditions to avoid equipment damage. The protection circuit includes overcurrent protection, overvoltage protection and temperature protection. Overcurrent protection is realized through current detection circuit, when the charging and discharging current exceeds the set threshold, the controller 8 immediately closes the MOSFET switch tube to cut off the charging and discharging circuit. Overvoltage protection is realized through voltage detection circuit, when the voltage of the energy storage cabinet exceeds the set threshold, the controller 8 stops the charging process to avoid overcharging; when the voltage of the energy storage cabinet is lower than the set threshold, the controller 8 stops the discharging process to avoid overdischarge. Temperature protection is realized through temperature sensor, when the temperature of the energy storage cabinet or the MOSFET switch tube exceeds the set threshold, the controller 8 reduces the charging and discharging current or cuts off the charging and discharging circuit to avoid overheating damage.

[0035] In practical applications, the working process of the charge-discharge control circuit is as follows: when the solar panel 6 or the wind power assembly 7 outputs electric energy, the controller 8 starts the charging process, adjusts the conduction time of the MOSFET switch tube through the PWM signal, controls the size of the charging current, and stores the electric energy into the energy storage cabinet. During the charging process, the controller 8 monitors the charging current, the voltage and the temperature of the energy storage cabinet in real time to ensure the safety and efficiency of the charging process. When the emergency pump station needs to be started, the controller 8 starts the discharging process, adjusts the conduction time of the MOSFET switch tube through the PWM signal, controls the size of the discharging current, and drives the first motor 2 or the second motor 3 to work. During the discharging process, the controller 8 monitors the discharging current, the voltage and the temperature of the energy storage cabinet in real time to ensure the safety and stability of the discharging process. Through the above design, the charge-discharge control circuit can realize efficient and safe charge-discharge management of the energy storage cabinet, and significantly improve the reliability and response speed of the hydraulic hoist emergency pump station.

[0036] In the present embodiment, the specific parameter settings of the charge-discharge control circuit, the generation algorithm of the PWM signal, the determination of the protection threshold, and other contents not disclosed in detail belong to the known technology or existing technology of those skilled in the art, which can be selected and optimized according to actual needs. Through the above design, the charge-discharge control circuit can realize multi-energy collaborative control, equipment state monitoring and intelligent management, and significantly improve the reliability, response speed and automation level of the hydraulic hoist emergency pump station.

[0037] The hydraulic hoist emergency pump station of the present embodiment realizes efficient, intelligent and reliable operation of the equipment through multi-energy collaborative power supply, dual-motor redundant driving, wireless communication control, real-time wheel speed monitoring and video intelligent monitoring. This technical solution not only effectively solves the technical bottlenecks of single energy, slow response speed and dependence on manual operation of traditional emergency pump stations, but also provides an advanced emergency power solution for water conservancy projects, gate control and other fields, which has significant economic benefits and social value. In practical applications, the emergency pump station can be widely used in water conservancy projects, gate control, ship equipment and other fields. For example, in water conservancy projects, when the gate cannot be normally closed due to power interruption, the emergency pump station can quickly start to provide hydraulic power through the oil pump 1 to drive the gate to close and avoid flood. Through multi-energy collaborative power supply, dual-motor redundant driving, wireless communication control, real-time wheel speed monitoring and video intelligent monitoring, the emergency pump station not only significantly improves the reliability and response speed of the equipment, but also reduces the frequency of manual intervention and maintenance cost, which has significant economic benefits and social value. At the same time, the modular design and intelligent management function of the system provide convenience for subsequent technical upgrading and expansion, which has wide application prospect.

In addition, the software algorithm of the controller 8, the specific implementation of the communication protocol, the details of the image recognition algorithm, etc. are not disclosed in detail, and these are routine technical means for those skilled in the art. According to actual needs, they can be selected and optimized. Through the above design, the hydraulic opening and closing machine emergency pump station can realize multi-energy collaborative control, equipment state monitoring and intelligent management, and significantly improve the reliability, response speed and automation level of the equipment.
