Description

Technical Field

[0001] The present application relates to the field of automation control technology, and in particular to an underground directly buried intelligent monitoring drive device. Background Art

[0002] Urban heating systems originate from heat and gas plants, passing through long main networks at transfer stations before being delivered to residential communities via a diode network. Given the length of these pipelines, multiple segmented valves are installed along the main lines to control and regulate the heat and gas sources. Pipe shafts, also known as manholes, are typically located where valves are installed to provide access for valve operation. Operators typically operate these manholes, which are sealed and confined spaces with poor ventilation, leading to the accumulation of toxic and flammable gases. Ventilators are used to draw in fresh air from the surface before entering to prevent accidents. Remote monitoring and control of the pipeline network primarily involves monitoring network parameters. This information, such as pressure, temperature, and flow, is transmitted to a real-time database server via various communication methods. This allows various departments to maintain a timely understanding of the network's operating status at each site and monitor network operations in real time. However, the geographical location of pipe wells is complex, transportation is inconvenient, the internal environment of pipe wells is harsh, which is not conducive to operation. Maintenance personnel cannot carry out daily inspections and maintenance work, and cannot monitor and control the internal environment and the position status of control valves in real time. When coordinating the supply of pipeline load, heat source and gas source, personnel need to enter the pipe wells to manually operate the valves, which has low work efficiency and high labor intensity. In addition, operations in pipe wells are limited space operations, the operation process is complicated and has certain safety risks. Utility Model Content

[0046] See Figure 1 、 Figure 2 and Figure 3 The underground direct-buried intelligent monitoring drive device of the embodiment of the present application includes: a main shell 6, a control component 5, a position detection component 3, a transmission unit 4, a sensor and a brushless motor 2. The main shell 6 is a hollow sealed structure. The position detection component 3 is arranged inside the main shell 6, communicates with the control component 5, and detects the position information of the drive device. The sensor is arranged outside the main shell 6, communicates with the control component 5, and detects the temperature and pressure outside the drive device. The brushless motor 2 is arranged inside the main shell 6, and the output shaft 410 of the brushless motor 2 passes through the bottom of the main shell 6 and is suitable for connecting to the rotating shaft of the reducer. The control component 5 is arranged inside the main shell 6 and is suitable for communicating with the upper computer to transmit information such as temperature, pressure and position detected by the drive device, and the control component 5 is communicated with the brushless motor 2 to control the rotation of the output shaft 410 of the brushless motor 2.

[0047] In this embodiment, the shell is made of stainless steel, which has good corrosion resistance and can be protected up to IP68. The underground direct-buried intelligent monitoring drive device can use 4G signals for wireless data transmission and control. At the same time, the device reserves a sensor interface, which can be connected to external temperature, pressure, flow and other sensors, and transmits data to the upper platform through wireless transmission, solving the technical problem of equipment installation in remote, scattered and inconvenient places for wiring control. Specifically, the underground direct-buried intelligent monitoring drive device of the present application is installed in a scene with complex geographical location, inconvenient transportation, harsh internal environment and convenient for maintenance personnel to enter for daily inspections. After receiving the communication command from the upper computer by using the remote control component 5, the control component 5 enters the working state, queries the current status information or controls the motor to amplify the torque through the transmission component and output to control the valve below. After completing the command, the status information is transmitted back to the upper computer. Among them, the position detection component 3 is arranged inside the main shell 6 and communicates with the control component 5 to detect the position information of the drive device. The sensor is arranged outside the main shell 6 and communicates with the control component 5 to detect the pipeline temperature and pressure information outside the drive device. A transmission unit 4 and a brushless motor 2 are provided inside the main shell 6. The brushless motor 2 is connected to the transmission unit 4 for transmission, driving the output shaft of the transmission unit 4 to rotate, which is used to drive the transmission component and transmit the amplified torque.

[0048] It should be noted that the brushless motor 2 in this application is composed of a motor body and a driver, and is a typical mechatronic product. Because the brushless DC motor operates in an autonomous manner, it does not require a separate starting winding on the rotor, as is the case with synchronous motors that start under heavy load under variable frequency speed regulation. Furthermore, it does not produce oscillations or step-outs when subjected to sudden load changes. This will not be further elaborated upon here.

[0049] In a specific embodiment, the underground directly buried intelligent monitoring drive device also includes: a transmission unit 4, a brushless motor 2 is arranged on the transmission unit 4, the transmission unit 4 is arranged inside the main shell 6, and is connected to the brushless motor 2 for transmission, and a control component 5 is arranged on the transmission unit 4, and is communicated with the transmission unit 4 to control the brushless motor 2 to drive the output shaft 410 of the transmission unit 4 to rotate.

[0050] Among them, the control component 5 includes a main control board 501, a drive board 502 and a main control board mounting plate 503. The main control board 501 and the drive board 502 are installed on the main control board mounting plate 503 and then fixed to the reduction bracket fixing plate 402.

[0051] Among them, the transmission unit 4 is used to amplify the torque of the brushless motor 2. The transmission unit 4 is connected to the brushless motor 2, and the output shaft 410 of the transmission unit 4 is connected to the valve. The brushless motor 2 can be started and the transmission unit 4 can be used to amplify the torque of the brushless motor 2, so that the valve can be opened or closed remotely, avoiding the complex geographical location of the pipe well, inconvenient transportation, harsh internal environment of the pipe well, which is not conducive to operation, and maintenance personnel cannot perform daily inspections and maintenance work, and cannot monitor and control the internal environment and the position status of the control valve in real time.

[0052] In this embodiment, the transmission unit 4 includes: a deceleration bracket fixing plate 402 and a transmission assembly. The deceleration bracket fixing plate 402 is a plate-shaped structure, and its edge position is connected to the inner side wall of the main shell 6, and the plate surface of the deceleration bracket fixing plate 402 is perpendicular to the length direction of the main shell 6. The transmission assembly is arranged on the bottom side of the plate surface of the deceleration bracket fixing plate 402, and the transmission assembly is connected to the brushless motor 2. The brushless motor 2 drives the transmission assembly to transmit and amplify the torque.

[0053] Among them, the deceleration bracket fixing plate 402 is arranged inside the main shell 6, and is used to fix the transmission component and the position detection component 3, and provide an internal installation position for the transmission component and the position detection component 3 in the main shell 6. The shape design of the deceleration bracket fixing plate 402 matches the interior of the main shell 6, so that the plate surface can be arranged along the vertical length direction of the main shell 6, and the interior of the main shell 6 is divided into an upper cavity and a lower cavity. The upper cavity is used to install the position detection component 3 and the shaft wheel, etc., and the lower cavity is used to install the transmission component, so that the underground direct-buried intelligent monitoring drive device is separated. Specifically, the internal space of the main shell 6 is a columnar structure, so the deceleration bracket fixing plate 402 is a circular plate structure, and the edge is fixed to the inner wall of the main shell 6, or the deceleration bracket fixing plate 402 is a 3 / 4 circle structure, reserving the installation position of the control component 5.

[0054] The control assembly 5 is a cubic structure as a whole, and is fixed to the inner side wall of the main housing 6 through the space reserved by the reduction bracket fixing plate 402.

[0055] In this embodiment, the transmission assembly includes: a handwheel connecting sleeve gear 401, a speed reducer mounting plate 402, an upper secondary transmission gear 403, an upper primary transmission gear 404, an upper tertiary transmission gear 405, a lower secondary transmission gear 406, a lower secondary transmission gear 407, a lower tertiary transmission gear 408, an output gear 409, and an output shaft 410. The upper primary transmission gear 404 and the lower primary transmission gear 406 are fixed to the speed reducer mounting plate 402, forming the first-stage transmission gear set. Motor 2 is fixed to the speed reducer mounting plate 402 and meshes with the upper primary transmission gear 404, transmitting the torque of motor 2 to the first-stage transmission gear set. The upper secondary transmission gear 403 and the lower secondary transmission gear 407 are fixed to the speed reducer mounting plate 402, forming the second-stage transmission gear set. The lower primary transmission gear 406 of the first-stage transmission gear set meshes with the upper secondary transmission gear 403, transmitting the torque to the second-stage transmission gear set. The upper three-stage transmission gear 405 and the lower three-stage transmission gear 408 are fixed to the reduction bracket fixing plate 402, forming the third-stage transmission gear set. The lower two-stage transmission gear 407 of the second-stage transmission gear set meshes with the upper three-stage transmission gear 405, transmitting torque to the third-stage transmission gear set. The output gear 409 and the output shaft 410 are fixed to the reduction bracket fixing plate 402, forming the fourth-stage transmission gear set. The lower three-stage transmission gear 408 of the third-stage transmission gear set meshes with the output gear 409, transmitting torque to the fourth-stage final transmission gear set. Position detection assembly 3 is provided adjacent to output shaft 410. Position detection assembly 3 includes an absolute encoder, an encoder bracket, and a position detection gear. The encoder gear meshes with the encoder gear on output shaft 410 to transmit the position of output shaft 410. The absolute encoder is electrically connected to control assembly 5 to transmit the position of output shaft 410 to control assembly 5.

[0056] Among them, unlike the conventional transmission unit 4, the transmission unit 4 used in this application is used to transmit and amplify the torque of the brushless motor 2, and the transmission component and the reduction bracket fixing plate 402 are designed according to the internal space of the main shell 6. The reduction bracket fixing plate 402 is designed to match the shape and installation position of the control component 5, which can maximize the optimization of the space inside the main shell 6, and the multi-stage transmission structure design of the transmission component can maximize the amplification and transmission of the torque of the brushless motor 2.

[0057] In a specific embodiment, the position detection component 3 and the deceleration bracket fixing plate are located in the same plane. The position detection component 3 is a square structure as a whole and is vertically arranged inside the main shell 6. The deceleration fixing plate is arranged horizontally, and the edge position of the deceleration bracket fixing plate is separated from the side wall of the main shell 6 by a preset installation space. The control component 5 is arranged in the preset installation space, and the control component 5 and the position detection component 3 are arranged up and down. By setting the control component 5 in the reserved installation space, the space utilization rate inside the main shell 6 can be greatly improved. Secondly, the control component 5 and the position detection component 3 are arranged up and down, which maximizes the use of the space inside the main shell 6, improves the overall space utilization rate, and ensures that the components do not interfere with each other and operate smoothly. At the same time, such a layout is also convenient for subsequent maintenance and upgrades.

[0058] In a specific embodiment, the underground directly buried intelligent monitoring drive device also includes: a grid ring, an output hole is provided at the bottom of the main shell 6, and the rotating shaft of the transmission assembly passes through the output hole, which is used to transmit the transmission shaft connected to the reducer, and the grid ring is embedded in the output hole, and the grid ring matches the transmission shaft of the reducer and the output hole of the transmission assembly.

[0059] In this embodiment, the output hole is designed to allow the output shaft 410 of the transmission unit 4 to pass through the bottom of the housing and connect to the transmission shaft of the reducer. The reducer's output shaft 410 is then connected to the valve, which can be used to sequentially open or close the valve. Specifically, a grid ring is provided on the outside of the output shaft 410 and embedded in the output hole at the bottom of the main housing 6. This ensures that the output shaft 410 of the transmission unit 4 is sealed when in normal use. The grid ring is a double-acting piston seal with low friction, no creep, low starting force, and high pressure resistance, making it suitable for use on the relatively rotating output shaft 410.

[0060] In a specific embodiment, the underground directly buried intelligent monitoring drive device also includes: a wiring compartment cover and a wiring panel. The wiring compartment cover is a hollow sealed structure, which is arranged on the main shell 6 and connected to the interior of the main shell 6. The wiring panel is arranged inside the wiring compartment cover, passing through the main shell 6 and the wiring compartment cover respectively, and is suitable for connecting an external power supply and control component 5, a position detection component 3, a sensor and a brushless motor 2.

[0061] Among them, the wiring board is used to electrically connect the underground direct-buried intelligent monitoring drive device to the external power supply, and to provide connecting wires for providing electrical energy to the control component 5, position detection component 3 and brushless motor 2 inside the main shell 6, as well as external sensors.

[0062] The wiring compartment cover is a sealed structure used to store and hold the wiring tray. It is located on the exterior sidewall of the main housing 6 and communicates with the interior of the main housing 6. The wiring compartment cover has a wiring hole whose diameter matches the wire diameter of the wiring tray, allowing the wiring tray inside the wiring compartment cover to connect to the external power supply through the hole.

[0063] In another embodiment, the wiring compartment cover comprises a wiring cover and a wiring portion. The wiring portion is a cylindrical structure with a hollow interior and two open ends. One open end is fixedly connected to and communicates with the outer side wall of the main housing 6. The wiring cover mates with the opening of the wiring portion and seals it. By opening the wiring cover, the wiring opening is connected to a cable, providing power to the underground buried intelligent monitoring drive device.

[0064] In a specific embodiment, the main housing 6 is made of stainless steel, which has good corrosion resistance and can provide protection up to IP68.

[0065] In a specific embodiment, the main shell 6 includes a shell and an upper cover. The shell is a hollow barrel-shaped structure, and the top of the shell is open. A fixed disk extends along the circumferential direction along the top opening of the shell. The fixed disk is an annular plate-shaped structure, and a fixing hole is provided on the plate surface of the deceleration bracket fixing plate 402. There are multiple fixing holes, which are arranged at intervals along the circumferential direction of the fixed disk. The upper cover matches the top opening of the shell, and the edge position of the upper cover is provided with mounting holes along the circumferential direction of the upper cover. The number and position of the mounting holes correspond one-to-one to the fixing holes opened on the fixed disk, and the upper cover is bolted to the shell, and a seal is provided at the top opening position of the shell.

[0066] In this embodiment, the underground direct-buried intelligent monitoring drive device also includes: a handwheel connecting sleeve gear 401, a handwheel 101, a handwheel extension shaft 102 and a handwheel limit switch assembly 103. The encoder bracket is arranged on the reduction bracket fixing plate 402, adjacent to the transmission assembly. The absolute value encoder is arranged on the encoder bracket. The absolute value encoder is connected to the position detection gear, the position detection tooth is engaged with the encoder gear of the transmission assembly, and the absolute value encoder is electrically connected to the control assembly 5 to transmit the position of the output shaft 410 of the transmission assembly to the control assembly 5.

[0067] The handwheel connecting sleeve gear 401 is fixed to the speed bracket fixing plate 402 and meshes with the output gear 409. The handwheel 101 is mounted on the handwheel extension shaft 102, which passes through the upper cover and connects to the handwheel connecting sleeve gear 401. By operating the upper handwheel 101, the handwheel extension shaft 102 meshes with the handwheel connecting sleeve gear 401, transmitting the torque of the handwheel 101 through the handwheel connecting sleeve gear 401 to the upper gear, thereby manually controlling the movement of the device. A handwheel limit switch assembly 103 is also located next to the handwheel connecting sleeve gear 401.

[0068] The control unit also includes a limit switch and a limit switch bracket. During manual operation, the handwheel 101 is pushed inward, causing the handwheel extension shaft 102 to engage with the handwheel connecting sleeve gear 401. Simultaneously, the handwheel extension shaft 102 contacts the handwheel limit switch assembly 103, closing the limit switch. The handwheel limit switch assembly 103 is electrically connected to the control assembly 5, providing a manual operation signal to the control assembly 5. Upon receiving the manual operation signal, the control assembly 5 limits the movement of the brushless motor 2.

[0069] It should be noted that the handwheel 101 is usually in a disengaged state. When manual work is required, it is pushed in, and a signal is provided to the control component 5. After receiving the signal, the control component 5 will limit the operation of the brushless motor 2, and only the handwheel 101 can be used to control the equipment below to avoid work conflicts.

[0070] Among them, this application can be completed in two ways. The first is to use the control component 5 for remote control, and the second is to use manual rotation of the hand wheel 101 for control.

[0071] In this embodiment, an output portion extends from the bottom of the shell toward the interior of the shell. The output portion is a hollow columnar structure and is located at the edge of the bottom of the shell. The output hole is opened at one end of the output portion away from the shell, and the output shaft 410 is located inside the output portion.

[0072] The output section is a hollow housing structure with openings at both ends for connection and communication with the bottom of the housing. The output shaft 410 of the transmission unit 4 passes through the housing and is located within the hollow output section. The output hole and grid ring are used to connect and transmit the output shaft 410 of the transmission unit 4 to the reducer's drive shaft within the output section, protecting both the output shaft 410 of the transmission unit 4 and the reducer's drive shaft from the underground environment.

[0073] The output portion is located at the bottom edge of the main housing 6, and both the output portion and the main housing 6 are columnar structures, with the length of the output portion parallel to the length of the main housing 6. In addition, the bottom of the main housing 6 is a planar structure. When the output shaft 410 of the transmission unit 4 is connected to the transmission shaft of the reducer, the bottom of the main housing 6 can be placed on the reducer, providing a stable installation location for the underground buried intelligent monitoring drive device.
