Description

Technical Field

[0001] This utility model relates to the field of relay station transmission application technology, specifically a relay station negative pressure transmission device. Background Technology

[0002] Transmission devices, also known as relay station transmission devices or transfer station transmission devices, are commonly used in water conservancy projects. They are used for long-distance liquid transportation, often involving the transfer of liquids via relay station negative pressure transmission devices. While their large capacity facilitates long-distance liquid transportation, similar transmission devices have several drawbacks in practical use. For example, they lack the ability to improve storage compatibility, limiting their applicability to different liquids and restricting their storage capacity. Furthermore, they lack the ability to improve the sealing of pipe connections, leading to loosening and leakage after prolonged use, thus reducing the sealing effect. Therefore, the design of relay station negative pressure transmission devices is necessary. Utility Model Content

[0003] The purpose of this invention is to provide a negative pressure transmission device for a relay station to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure transmission device for a relay station, comprising a walking frame, a mixing component, a transmission tank, a control box, a hydraulic cylinder, and a hydraulic transmission component; the bottom of the walking frame is equipped with steering wheels, the design of which enables the entire device to move flexibly, facilitating transport and position adjustment in different locations and environments, greatly improving ease of use; simultaneously, the steering wheels also enable steering, allowing the walking frame to flexibly turn according to the operator's intention, further enhancing its applicability; a vertical support rod is installed at the top of the upper surface of the walking frame, and the control box is installed at the top of the vertical support rod; the design of the vertical support rod not only provides stability... The control box is supported and positioned within the operator's optimal field of vision for easy monitoring and operation. As the control center of the entire device, the control box integrates advanced control systems and sensors, enabling real-time monitoring and control of the transmission device's operating status. A hydraulic cylinder is installed at the center of the control box, with a hydraulic piston rod mounted on it. A sealing cover is installed at the bottom of the piston rod, connected to the hydraulic cylinder via the piston rod. The hydraulic cylinder, acting as a power source, precisely controls the opening and closing of the sealing cover via commands from the control box, thereby sealing and releasing materials within the transmission tank. When material needs to be transferred, the control box issues a command. A hydraulic cylinder drives a hydraulic piston rod to rise, opening the sealing cover and drawing material into the transfer tank under negative pressure. Once the material reaches the designated location, the control box issues another command, causing the hydraulic cylinder to descend and close the sealing cover, ensuring no leakage during transfer and significantly improving efficiency and safety. The transfer tank is mounted on the upper surface of the traveling frame via a fixed base. As the core component for material transfer, the transfer tank's design fully considers the requirements of negative pressure transfer, ensuring stability and safety during transport. The fixed base not only provides stable support for the transfer tank but also guarantees its stability and reliability on the traveling frame, further enhancing efficiency. The stability and durability of the entire device are ensured by a mixing component installed at the bottom of the transfer tank. This component's design allows for thorough mixing of materials during transport, guaranteeing uniformity and consistency and improving transport quality. A hydraulic transfer component is installed on the upper surface of the frame, connected to a sealing cover via a conveying pipe. As the power transmission component of the entire device, the hydraulic transfer component achieves precise power transmission and negative pressure suction of materials, further enhancing transport efficiency and stability. Handles are installed on both sides of the transfer tank, facilitating operator movement and operation, and improving the overall ease of use of the device.

[0005] Preferably, the mixing assembly is equipped with a mixing motor, and a main drive wheel is installed on the output end of the mixing motor. The main drive wheel is connected to the driven wheel via a drive belt. A second mixing rod is installed on the main drive wheel, and a first mixing rod is installed on the driven wheel. The design of the second and first mixing rods allows the material to receive a more uniform mixing force in the transfer tank, further improving the mixing effect. The mixing motor, as a power source, drives the driven wheel to rotate through the main drive wheel and drive belt, thereby achieving synchronous movement of the first and second mixing rods and ensuring continuous mixing of the material during the transfer process. In addition, the belt connection design between the main drive wheel and the driven wheel not only simplifies the transmission structure but also improves the stability and reliability of the transmission, further ensuring the uniformity and consistency of the material transfer.

[0006] Preferably, the hydraulic transmission assembly is equipped with a pressure control pump. The design of the pressure control pump provides a stable pressure output for the hydraulic transmission assembly, ensuring the smoothness and stability of material transmission.

The control valve is connected to the intermediate filter frame via a guide pipe, and the liquid guide end of the pressure control pump is fixedly connected to the liquid outlet pipe. The connection between the control valve and the intermediate filter frame via the guide pipe achieves precise control of the material transmission path and also facilitates the cleaning and maintenance of the intermediate filter frame. The fixed connection of the liquid outlet pipe ensures that the material can be smoothly discharged from the hydraulic transmission assembly and enter the next process. The overall design not only improves the efficiency and stability of material transmission but also greatly simplifies the operation process and reduces maintenance costs.

[0007] Preferably, the control box is equipped with lifting rods on both sides of the top. The lifting rods make the control box easy to carry and move, increasing the flexibility and portability of the device. A touch screen is nested on the front surface of the control box. The touch screen can display the device's working status, parameter settings, and fault alarms, facilitating real-time monitoring and operation by the operator. In addition, the control box integrates an advanced control system that can intelligently control and manage the entire negative pressure transmission device, ensuring the stability and efficiency of the device's operation.

[0008] Preferably, a frame is installed at the top of the upper surface of the walking frame, and a horizontal reinforcing plate is installed between the support plates of the frame. The design of the frame and the horizontal reinforcing plate enhances the structural strength of the walking frame and improves the stability and load-bearing capacity of the device. A maintenance tool box is installed on the upper surface of the horizontal reinforcing plate. The maintenance tool box can store various maintenance tools and spare parts, which facilitates maintenance personnel to perform daily maintenance and emergency fault handling of the device. This design makes the entire negative pressure transmission device safer and more reliable in operation, and also facilitates the operation and management of maintenance personnel.

[0009] Preferably, rectangular fixing plates are installed at both ends of the walking frame, and a push frame is installed at one end of the upper surface of the walking frame. The design of the push frame allows the walking frame to be easily pushed by human or mechanical means, thereby facilitating the movement and positioning of the entire negative pressure transmission device. The rectangular fixing plates are used to fix and connect the walking frame with other components, ensuring that the connection between the components is stable and reliable during operation. This design not only improves the flexibility and portability of the device, but also enhances the stability and durability of its overall structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When materials need to be transferred, the control box issues a command, and the hydraulic cylinder drives the hydraulic piston rod to rise, opening the sealing cover. The material is then sucked into the transfer tank under negative pressure. After the material is transferred to the designated position, the control box issues another command, and the hydraulic cylinder drives the hydraulic piston rod to fall, closing the sealing cover and ensuring no leakage during the transfer process. This greatly improves the efficiency and safety of the transfer. The transfer tank is mounted on the upper surface of the walking frame via a fixed base. As the core component for material transfer, the transfer tank is designed to fully consider the requirements of negative pressure transfer, ensuring the stability and safety of the material during the transfer process. The fixed base not only provides stable support for the transfer tank but also ensures its stability and reliability on the walking frame, further enhancing the stability and durability of the entire device. A mixing component is installed at the bottom of the transfer tank. The design of the mixing component allows the material to be fully mixed during the transfer process, ensuring the uniformity and consistency of the material transfer and improving the transfer quality.

[0012] 2. The installation of the pressure gauge in this utility model allows operators to monitor the working pressure of the hydraulic transmission components in real time, thereby adjusting the output of the pressure control pump in a timely manner, ensuring the safety and reliability of the transmission process. The control valve is connected to the intermediate filter frame through a guide pipe, and the liquid guide end of the pressure control pump is fixedly connected to the liquid outlet pipe. The connection between the control valve and the intermediate filter frame through the guide pipe enables precise control of the material transmission path, and also facilitates the cleaning and maintenance of the intermediate filter frame. The fixed connection of the liquid outlet pipe ensures that the material can be smoothly discharged from the hydraulic transmission components and enter the next process. The overall design not only improves the efficiency and stability of material transmission, but also greatly simplifies the operation process and reduces maintenance costs.
