DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0022] Example:

[0023] See also Figure 1 A hydraulic cylinder oil inlet detection device comprises a base 1 and an oil storage tank 3 fixedly mounted on one end of the surface of the base 1, and an oil pump 4 is connected to the side wall flange of the oil storage tank 3.

[0024] Among them, the base 1 is used as the installation platform for the detection component 2, the oil storage tank 3 and the oil pump 4, and the design fully considers stability, load-bearing capacity and ease of use. And the base 1 is made of strong and durable materials, such as high-strength steel or cast iron, to ensure that it can withstand various forces generated by the detection device during operation. The bottom of the base 1 is usually equipped with an anti-slip pad or anchor bolts to ensure that it can be firmly fixed on the ground or workbench to prevent displacement due to vibration or external force. The surface of the base 1 is finely processed to ensure the flatness and accuracy of each component during installation. The detection component 2, the oil storage tank 3 and the oil pump 4 are firmly mounted on the base 1 by bolts or other fasteners to ensure that they will not shake or fall off during operation. At the same time, sufficient space is reserved on the base 1 so that installation and maintenance personnel can operate conveniently. In addition, the design of the base 1 also fully considers the wiring requirements. Special wire troughs or wiring holes can be provided on the surface of the base 1 for wiring and wiring, making the electrical connection of the entire detection device more neat, beautiful and safe.

[0025] Among them, the oil tank 3 is the main storage container for hydraulic oil, and its design fully considers the storage environment and temperature control requirements of the oil. In order to ensure that the oil maintains a constant temperature during storage, the oil tank 3 is made of high-quality thermal insulation material. This thermal insulation material has good thermal insulation performance, which can effectively isolate the influence of external temperature on the oil and keep the oil within a constant temperature range. The thermal insulation design of the oil tank 3 not only helps to maintain the stable performance of the oil, but also prevents problems such as waxing or deterioration of the oil caused by temperature changes. At the same time, the constant oil temperature also helps to improve the working efficiency of the oil pump 4 and ensure the smooth progress of the oil intake process. In addition, the oil tank 3 also has sufficient capacity to meet the needs of long-term continuous work.

[0026] Among them, the oil delivery pump 4 adopts frequency conversion control technology, which can adjust the working frequency of the pump in real time according to actual needs, thereby effectively reducing energy consumption while ensuring the oil intake.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A hydraulic cylinder oil inlet detection device includes a detection component 2 fixedly installed on the other end of the surface of a base 1, and the detection component 2 is composed of a supporting mechanism 21, a transfer mechanism 22 and a detection mechanism 23. The supporting mechanism 21 includes a chassis 211, a supporting cylinder 212 and a branch pipe 213; the transfer mechanism 22 includes a transfer ball 221, a spring 222 and a sealing ball 223; the detection mechanism 23 includes a flange cylinder 231, a detector 232, a flow detection module 233, a pressure detection module 234, an alarm module 235 and a control module 236.

[0028] Among them, the design of the support mechanism 21 provides stable support for the entire detection device and ensures that the oil can flow smoothly during the flow process. The fixed connection between the chassis 211 and the base 1 ensures the stability of the support mechanism 21, thereby ensuring the overall stability of the detection device. The support cylinder 212, as a key component connecting the chassis 211 and the transfer mechanism 22, not only withstands the pressure generated when the oil flows, but also ensures the strength and sealing of the connection by welding. In addition, the branch pipe 213 provided on the side wall is connected to the flange of the oil pump 4, so that the oil can smoothly enter the support mechanism 21 from the oil storage tank 3 through the oil pump 4, and finally flow to the transfer mechanism 22 and the detection mechanism 23. This design not only simplifies the oil flow path, reduces the risk of leakage and blockage, but also improves the working efficiency of the detection device. And the connection between the branch pipe 213 and the oil pump 4 adopts a flange connection, which is not only convenient for installation and disassembly, but also effectively prevents oil leakage.

[0029] Among them, the transfer mechanism 22 plays a vital role. It is not only a connecting bridge between the support tube 212 and the detection mechanism 23, but also plays a key regulating role in the process of oil flow. The transfer ball 221 is a hollow sphere, and its bottom is firmly connected to the top of the support tube 212 by welding, ensuring that the oil can flow smoothly from the support tube 212 to the transfer ball 221. At the same time, the top of the transfer ball 221 is connected to the bottom of the detection mechanism 23 by a flange. This connection method not only ensures the stability of the connection, but also facilitates disassembly and maintenance. Inside the transfer ball 221, the spring 222 and the sealing ball 223 together constitute a dynamic sealing system. The two ends of the spring 222 are fixedly connected to the inner top of the transfer ball 221 and the surface of the sealing ball 223 respectively. This connection method allows the sealing ball 223 to move freely under the action of the spring force. When the oil flows from the support tube 212 into the transfer ball 221, the sealing ball 223 moves upward due to the pressure of the oil and separates from the inner bottom of the transfer ball 221, thereby allowing the oil to pass through. When the pressure of the oil flowing through is lower than a certain threshold, the spring 222 will maintain a certain preload force to ensure that the sealing ball 223 is always tightly fitted with the inner bottom of the transfer ball 221 to prevent the oil from flowing back.

[0030] Among them, the support tube 212 is a key component connecting the chassis 211 and the transfer ball 221, and its design and manufacturing process are particularly important. In order to ensure the smoothness and sealing of the oil during the flow process, the two ends of the support tube 212 are seamlessly welded to the opposite ends of the chassis 211 and the transfer ball 221 respectively. Seamless welding is a high-quality connection method, which can ensure that there are no gaps and leaks in the welding parts, thereby ensuring the connection strength and sealing between the support tube 212 and the chassis 211 and the transfer ball 221. This connection method not only improves the stability and reliability of the entire detection device, but also reduces the risk of leakage and blockage. In addition, the interiors of the support tube 212 and the transfer ball 221 are interconnected, which allows the oil to smoothly enter the transfer ball 221 from the support tube 212 and then flow to the detection mechanism 23. This design not only optimizes the oil flow path, but also improves the working efficiency of the detection device.

[0031] Among them, the detection mechanism 23, as the core part of the hydraulic cylinder oil inlet detection device, integrates a variety of functional modules to achieve accurate detection and monitoring of key parameters such as oil flow and pressure. The main structure of the detection mechanism 23 is a flange cylinder 231, which is tightly connected to the transfer ball 221 through a flange connection to ensure that the oil can flow smoothly from the transfer mechanism 22 into the detection mechanism 23. A hose is provided at the top of the flange cylinder 231, which is convenient for users to fill the hydraulic cylinder with oil through the hose, and a detector 232 is installed on the outer wall. It is the core component of the detection mechanism 23 and is responsible for detecting the oil. The detector 232 includes an annular main body, and a flow detection module 233, a pressure detection module 234, an alarm module 235 and a control module 236 are evenly spaced on the outer wall of the main body. This layout not only allows each module to be evenly distributed, improves the accuracy and stability of the detection, but also facilitates later maintenance and replacement. The detection ends of the flow detection module 233 and the pressure detection module 234 are both installed inside the flange cylinder 231, and they can directly contact the flowing oil, thereby realizing real-time detection of flow and pressure. These two modules are electrically connected to the control module 236, and can transmit the detected data to the control module 236 for processing and analysis. As the "brain" of the detection mechanism 23, the control module 236 is responsible for processing, comparing and judging the received data. When the detected flow or pressure exceeds the preset threshold, the control module 236 will immediately trigger the alarm module 235 and send out an audible and visual alarm signal to remind the operator to take timely measures. At the same time, the control module 236 will also send a signal to the oil pump 4 through an electrical connection to adjust its working state to maintain the stability of the oil flow and pressure.

[0032] The working principle of the hydraulic cylinder oil inlet detection device: During the entire working process, the oil pump 4 is responsible for pumping the oil in the oil tank 3 to the support mechanism 21 to provide a continuous supply of oil for detection. The control module 236 serves as the "brain" of the entire detection device, and ensures the accuracy and reliability of the detection process by controlling and coordinating each module. Next, the oil flows into the transfer mechanism 22 through the branch pipe 213 and the support cylinder 212. The transfer ball 221 in the transfer mechanism 22 is a key component, and the spring 222 and the sealing ball 223 installed inside it play the role of an automatic switch. When the oil flows in, the sealing ball 223 is automatically opened by the oil pressure to allow the oil to pass; when the oil stops flowing or the pressure is lower than a certain threshold, the sealing ball 223 is automatically closed due to the elastic force of the spring 222 to prevent oil leakage and backflow. This design ensures the smoothness and sealing of the oil during the flow process. Subsequently, the oil enters the detection mechanism 23. The flange cylinder 231 of the detection mechanism 23 is flange-connected to the transfer ball 221 to ensure that the oil can continue to flow. On the outer wall of the flange cylinder 231, a detector 232, a flow detection module 233, a pressure detection module 234, an alarm module 235 and a control module 236 are installed. The detector 232 detects the oil through the sensor thereon, and the flow detection module 233 and the pressure detection module 234 monitor the flow and pressure data of the oil respectively, and transmit these data to the control module 236. The control module 236 processes and analyzes these data. When the data exceeds the preset threshold, it will trigger the alarm module 235 to send an alarm signal, and at the same time send a signal to the oil pump 4 to adjust its working state to maintain the stability of the oil flow and pressure.

[0033] It should be noted that the specific models and specifications of the flow detection module 233, the pressure detection module 234, the alarm module 235, the control module 236, the oil pump 4, the sealing ball 223, and the spring 222 need to be selected and determined according to the actual specifications of the device. The flow detection module 233 can adopt the flow sensor in the prior art, the pressure detection module 234 can adopt the pressure sensor in the prior art, the alarm module 235 can adopt the alarm in the prior art, and the control module 236 can adopt the single-chip microcomputer in the prior art. At the same time, the program used by the control module 236 to trigger the alarm when the data exceeds the preset threshold is widely used in related equipment such as temperature alarm, flow alarm, pressure alarm, etc. in the prior art, and also belongs to the prior art. The specific selection and calculation method of the above components adopts the prior art in this field, so it will not be described in detail.

[0034] The flow detection module 233, the pressure detection module 234, the alarm module 235, the control module 236, and the power supply and principles of the oil pump 4 are clear to those skilled in the art and will not be described in detail herein.

[0035] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
