Description

Technical Field

[0001] This invention relates to metallurgical industry technology, and more specifically, to a power supply device and control method for an oil replenishment device. Background Technology

[0002] Currently, in many similar equipment environments with winch drive structures, the original design did not take into account changes in environment and working conditions. For example, in the thick plate transfer machine system, as production capacity increases, the equipment utilization rate has nearly doubled. At the same time, with the increase in rolling varieties, the degree of baking of the equipment in the area by hot charging and hot delivery of billets far exceeds the design capacity. As a result, the original periodic manual oiling maintenance can no longer ensure the stability of the current equipment, and there have been multiple cases of wire rope breakage in the winch drive structure due to lack of oil.

[0003] After the wire rope broke, various oil replenishment methods were tried, but due to the lack of a power supply box in the area, centralized oil replenishment using oil pumps could not be implemented. To ensure the normal operation of the winch, a temporary manually operated gravity oil replenishment device was constructed, employing a drip-type oil replenishment method. While this solved the short-term oil replenishment needs, the manual oil replenishment operation still required personnel to enter the area, and was still affected by factors such as rotating equipment, uneven ground conditions, and irregular oil replenishment frequency, resulting in low efficiency and numerous potential safety hazards.

[0004] Existing patent applications, such as patent application number 202311626254.X, disclose a three-phase inverter power supply device for radar vehicles. This device uses 540V DC power as its energy source and outputs three-phase electricity. However, its patented technology is applied to high-power mobile vehicle platforms, which differ significantly from the operating environment and safety requirements of equipment like transfer machines. Therefore, it cannot provide a technical solution for powering on-site refueling devices. This patented technology differs significantly from the technology of this invention. This invention uses a battery pack inverter to boost voltage, solving the power supply problem for relevant on-site equipment and addressing related safety hazards. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a power supply device and control method for a refueling device, which uses a rechargeable battery as an energy source and an inverter circuit to boost the voltage to obtain a 220V AC power supply, thereby solving the refueling problem of the transfer machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The first aspect of the present invention provides a power supply device for a refueling device, including a battery body;

[0008] The battery body is connected to the charging pile;

[0009] The battery body contains an inverter boost circuit, a Bluetooth control relay, a Bluetooth switch, a socket panel, and a strong magnetic circuit.

[0010] The inverter boost circuit is connected to the Bluetooth control relay;

[0011] The Bluetooth control relay is configured with two paths, one of which is connected to the output side of the Bluetooth switch, and the other is connected to the Bluetooth control module;

[0012] The Bluetooth switch is connected to the socket panel and the strong magnetic circuit respectively;

[0013] The socket panel is connected to the pump on the oil supply device;

[0014] The strong magnetic circuit is connected to the magnetic attraction point on the electric pile.

[0015] Preferably, the Bluetooth switch is connected to the socket panel and the strong magnetic circuit respectively via an air switch.

[0016] Preferably, the battery body and the charging pile are connected in conjunction with a power receiving structure;

[0017] The power receiving structure includes an assembly guide groove, a power receiving pile head, and a power receiving guide groove;

[0018] The assembly guide groove is formed on the charging pile, with one end of the assembly guide groove being open for inserting the battery body, and the other end being closed.

[0019] One end of the power receiving pile is connected to the closed end of the assembly guide groove, and the other end is provided with a magnetic contact.

[0020] The power receiving channel is formed on the battery body. One end of the power receiving channel is set to be open for insertion into the power receiving terminal, and the other end is also provided with a magnetic contact.

[0021] The two magnetic contacts engage in contact.

[0022] Preferably, the open end of the assembly guide groove is provided with an inlet chamfer;

[0023] The angle of the introduced chamfer is 4°±0.5°.

[0024] Preferably, the magnetic contacts all include an S point, an N point, a neutral wire point, and a live wire point.

[0025] Preferably, the magnetic attraction point is located on the closed end of the assembly guide groove;

[0026] A steel plate is provided on the battery body at the position corresponding to the magnetic attraction point.

[0027] Preferably, the battery body also includes a main power button, a battery power monitoring button, an output voltmeter, a battery power meter, a temperature detection module, a temperature control panel, a multi-stage cooling fan, and an overload protector.

[0028] A second aspect of the present invention provides a control method for a power supply device for an oil replenishment device based on the first aspect of the present invention, comprising the following steps:

[0029] S1, Press the main power button to start the battery body;

[0030] S2, check if the polarity of the battery body is correct. If yes, the battery body outputs voltage; if no, the battery body has no output and automatically shuts down.

[0031] S3, the temperature detection module is activated;

[0032] S4. If the internal temperature of the battery body is greater than a set value, the inverter boost circuit stops operating; otherwise, the inverter boost circuit starts.

[0033] S5, the input power of the Bluetooth control relay is turned on;

[0034] S6, the Bluetooth control relay receives information and starts;

[0035] S7, the on-site oil replenishment device has started operating.

[0036] Preferably, in step S4, if the internal temperature of the battery body is greater than a set value of 50°C, the multi-stage cooling fan is activated to dissipate heat.

[0037] This invention provides a power supply device and control method for an oil replenishment system, applied to oil replenishment in the oil canisters of a transfer machine. It allows for on-demand oil pump replenishment using a battery, based on the rhythm, frequency, and operating conditions of the continuously cast slab feed. This essentially eliminates the need for the transfer machine to stop for oil replenishment. Furthermore, during battery operation, there is no physical contact between the user and the battery. After oil replenishment, the strong connection between the battery and the charging pile disappears simultaneously as the user turns off the 220V AC output using the control panel on their mobile phone, at which point the user can remove the battery. This significantly improves the efficiency of maintaining the wire rope reel of the transfer machine, completely avoiding direct contact with the 220V output during the oil replenishment process.

[0044] To better understand the above-mentioned technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] Combination Figures 1 to 5 As shown, the present invention provides a power supply device for a refueling device, including a battery body 100.

[0046] The battery body 100 is connected to the charging pile 200.

[0047] The battery body 100 contains an inverter boost circuit 1, a Bluetooth control relay 2, a Bluetooth switch 3, a socket panel 4, and a strong magnetic circuit 5.

[0048] Inverter boost circuit 1 adopts a classic DC 12V to AC 220V inverter boost circuit, and its circuit is as follows: Figure 1 As shown.

[0049] The Bluetooth control relay 2 includes an SRD-05VDC-SL-C relay 201, an ESP32 Bluetooth control module 202, and an HLK-PM01 isolated power supply 203. The ESP32 Bluetooth control module 202 and the HLK-PM01 isolated power supply 203 are used to control the opening and closing of the SRD-05VDC-SL-C relay 201. The SRD-05VDC-SL-C relay 201 is connected to the ESP32 Bluetooth control module 202 for Bluetooth information sampling and communication, controlling the opening and closing of the SRD-05VDC-SL-C relay 201.

[0050] The inverter boost circuit 1 inverts and boosts the DC 12V voltage to AC 220V, and then connects it to the HLK-PM01 isolated power supply 203 and the SRD-05VDC-SL-C relay 201 respectively. The HLK-PM01 isolated power supply 203 outputs 5V voltage to the ESP32 Bluetooth control module 202 to control the SRD-05VDC-SL-C relay 201. When the ESP32 Bluetooth control module 202 is powered on, the SRD-05VDC-SL-C relay 201 is turned on.

[0051] The Bluetooth control module ESP32 202 is used to sample and control the SRD-05VDC-SL-C relay 201.

[0052] Bluetooth switch 3 is connected to socket panel 4 and strong magnetic circuit 5 via air switch 6.

[0053] The socket panel 4 is connected to the pump on the field oil supply device.

[0054] The SRD-05VDC-SL-C relay 201 outputs 220 volts to supply the load on the output side of the Bluetooth switch 3.

[0055] The strong magnetic circuit 5 is connected to the magnetic attraction point 2001 on the electric pile 200.

[0056] The battery body 100 and the charging pile 200 are connected by a power receiving structure.

[0057] The power receiving structure includes an assembly guide groove 7, a power receiving pile head 8, and a power receiving guide groove 9.

[0058] The assembly guide groove 7 is provided on the charging pile 200. One end of the assembly guide groove 7 is set to be open for guiding the battery body 100, and the other end is set to be closed. The magnetic attraction point 2001 is set on the closed end of the assembly guide groove 7.

[0059] One end of the power receiving pile 8 is connected and fixed to the closed end of the assembly guide groove 7, and a magnetic contact is provided on the end face of the other end.

[0060] The power receiving channel 9 is formed on the battery body 100. One end of the power receiving channel 9 is set to be open and located on the side of the lower end of the battery body 100 for inserting the power receiving terminal 8. The other end is also provided with a magnetic contact.

[0061] Both magnetic contacts include point S10, point N11, neutral point 12, and live point 13. The corresponding points on the two magnetic contacts make contact and cooperate to form a power supply.

[0062] An inlet chamfer 22 is provided on the open end of the assembly guide groove 7. The angle of the inlet chamfer 22 is 4°±0.5°, which facilitates the inlet of the battery body 100.

[0063] The 220V output terminal of the battery body 100 is located within the power receiving groove 9 and employs magnetic contacts. During the process of pushing the battery body 100 into the assembly guide groove 7 of the charging pile 200, the two sides of the assembly guide groove 7 have 4° chamfers 22 to facilitate the connection between the battery body 100 and the charging pile 200. Simultaneously, if the power receiving pile head 8 is deformed or damaged, the S-point 10 and N-point 11, located above and below the magnetic contacts, will repel each other, preventing the connection from being completed, thus providing a protective function.

[0064] After the battery body 100 is connected to the charging station 200, the user can scan the code with their mobile phone to remotely control the Bluetooth switch 3 to turn it on / off, thus physically enabling the user to turn the battery body 100 on and off, while avoiding contact with the 220-volt battery body 100 to ensure safe operation.

[0065] A steel plate 14 is provided on the battery body 100 at the position corresponding to the magnetic attraction point 2001.

[0066] After the battery body 100 is connected to the charging pile 200, the magnetic attraction point 2001 on the charging pile 200 starts working after the user scans the code to power on. The magnetic attraction point 2001 is attracted to the steel plate 14 corresponding to the magnetic attraction point 2001, forming an attraction force of more than 3 kg. This design ensures that even when the battery body 100 is outputting 220V AC power at startup, in the event of an external impact, the battery body 100 and the charging pile 200 will not accidentally separate, causing the magnetic attraction point to remain charged and thus preventing the risk of electric shock.

[0067] The battery body 100 is also equipped with a main power button 15, a battery power monitoring button 16, an output voltage meter 17, a battery power meter 18, a temperature detection module, a temperature control panel 19, a multi-stage cooling fan 20, and an overload protector 21.

[0068] The outer casing of the battery body 100 is made of PVC material, which is completely insulated.

[0069] Combination Figure 6 As shown, the present invention also provides a control method for a power supply device for an oil replenishment device based on the present invention, comprising the following steps:

[0070] S1, press the main power button 15, the battery unit will start at 100;

[0071] S2, check if the polarity of the battery body 100 is correct. If it is, the current of the battery body 100 is less than the overload protection current, and the voltage output of the battery body 100 is reduced. If not, the battery body 100 has no output and automatically shuts down.

[0072] S3, Temperature detection module starts;

[0073] S4. Is the internal temperature of the battery body 100 greater than 50°C? If yes, the inverter boost circuit 1 stops operating; if no, the inverter boost circuit 1 starts.

[0074] S5, Bluetooth control relay 2 input power is turned on;

[0075] S6, Bluetooth control relay 2 receives information and starts;

[0076] S7, the on-site oil replenishment device has started operating.

[0077] In step S4 above, if the internal temperature of the battery body 100 is greater than the set value of 50°C, the multi-stage cooling fan 20 will start to dissipate heat.

[0078] See again Figure 5 As shown, the operation of the control method of the present invention on the battery body 100 is as follows:

[0079] After pressing the main power button 15 (the battery power monitoring button 16 can be pressed separately to view the current battery power on the battery meter 18), the inverter boost circuit 1 and the Bluetooth control relay 2 are successfully connected, and the first-stage cooling fan in the multi-stage cooling fan 20 starts by default; simultaneously, the temperature control panel 19 displays the current temperature of the battery body 100, and the user can also set the starting temperature of the second-stage fan in the multi-stage cooling fan 20 according to the internal temperature of the battery body 100; using the IoT code, the Bluetooth control relay 2 can be started on the APP (mobile phone), at which time the output voltmeter 17 will display the inverter voltage, indicating that the magnetic contact has normally output 220V AC power.

[0080] In summary, this invention, by combining a commonly used 220V AC battery pack with a redesigned battery device and control system for safe operation in specific field environments, solves the problem of providing temporary power to on-site equipment in situations where 220V AC power is unavailable. It utilizes a rechargeable battery as an energy source, employs an inverter circuit to boost the voltage to 220V AC power, and incorporates specially designed safety connectors for connecting to power stations tailored to the specific environment and requirements. Combined with internal battery temperature control and wireless control, it provides power to electrical equipment in areas lacking electricity, such as oil pumps for refueling oil jugs on transfer machines, improving personnel safety and reducing equipment maintenance difficulty. This invention ensures the safe use of 220V AC batteries in harsh environments; from the safety design of the battery's hardware interface to the software, hardware, design, and control of the energy source output; it provides intuitive battery status monitoring and power information, offering a user-friendly and convenient settings interface for quick and safe battery operation. It also ensures stability against thermal and electromagnetic radiation under harsh conditions.
