Description

Technical Field

[0001] This utility model belongs to the technical field of coal bunker void measurement equipment, and particularly relates to a coal bunker void distance measurement device. Background Technology

[0002] In coal storage and transportation, the empty space distance (i.e., the remaining height of the space from the coal pile surface to the top of the bunker) is a key monitoring parameter, directly affecting inventory management, safe production, and automated control. Traditional measurement methods mostly rely on manual use of sounding hammers or fixed sensors, which suffer from low efficiency, poor accuracy, and susceptibility to dust interference. While some mechanical measuring devices can achieve automatic measurement, their complex structures are prone to jamming or wear, and their reliability is insufficient in the harsh environment of high temperature, high humidity, and high dust in coal bunkers. In addition, the measuring heads of existing equipment are easily affected by the coal accumulation pattern, leading to significant data deviations. Therefore, there is an urgent need for an automated measuring device that is simple in structure, highly adaptable, and highly accurate. Utility Model Content

[0026] Please see Figure 1-4 To achieve the above objectives, this embodiment provides a coal bunker empty layer distance measuring device, including a fixed column 1 and a measuring instrument 2.

[0027] In this embodiment, the fixing column 1 is vertically fixed inside the coal bunker, typically installed on a stable structure on the top or side wall of the coal bunker. The fixing column 1 serves as the supporting foundation for the entire device, ensuring the stability and vertical positioning of the measuring instrument 2 within the coal bunker, and preventing measurement deviations caused by coal pile tilting or collapse.

[0028] In this embodiment, the mounting base 3 is fixed to the top of the fixing column 1 or at a preset position on the side wall, and is fixed to the fixing column 1 by mechanical connection (such as bolts or welding). The mounting base 3 carries the measuring instrument 2 and provides a through channel for the measuring ruler 6 and the protective frame 5, while the fixing rod on the side wall enhances the connection strength with the fixing column 1.

[0029] In this embodiment, the measuring instrument 2 is fixed to the fixed column 1 via the mounting base 3, located above or at the side entrance of the empty layer in the coal bunker. The measuring instrument 2 is the core measuring unit, which includes a telescopic mechanism, a measuring ruler 6, and a sensing head 117, and is responsible for detecting the distance of the empty layer and outputting the data.

[0030] In this embodiment, the telescopic component 4 is located inside the measuring instrument 2, connecting the mounting base 3 and the input end of the measuring ruler 6. The telescopic component 4 controls the extension and retraction of the measuring ruler 6, specifically through the drive motor and measuring tape 9 inside the tape retraction box 8 to achieve automatic extension and retraction, adapting to the measurement of empty layers at different depths.

[0031] In this embodiment, the protective frame 5 penetrates the mounting base 3 and extends into the empty space of the coal bunker, enclosing the measuring ruler 6. The protective frame 5 can prevent coal dust, broken coal, or humid environments from contaminating or damaging the measuring ruler 6, ensuring the long-term reliability of the measuring ruler 6 under complex working conditions.

[0032] In this embodiment, the measuring ruler 6 is located inside the protective frame 5, with its upper end connected to the measuring tape 9 of the telescopic component 4 and its lower end connected to the sensing head 117. The measuring ruler 6 serves as a carrier for length measurement, achieving vertical displacement through telescopic control, and converting physical displacement into electrical or mechanical signals.

[0033] In this embodiment, the sensing head 117 is installed at the end of the measuring ruler 6 and connected to the measuring ruler 6 via the sensing base 10. The sensing head 117 detects the position on the surface of the coal pile. When the sensing head 117 contacts the coal pile, it triggers a signal to stop the extension of the measuring ruler 6 and records the current displacement value.

[0034] In this embodiment, the drive motor is located inside the tape measure box 8 and is mechanically connected to the measuring tape 9. It provides power, controls the automatic extension and retraction of the measuring tape 6, responds to measurement commands, and achieves precise displacement control.

[0035] In this embodiment, the sensing base 10 is located inside the sensing head 117 and has a hollow structure; the movable block is located at the end of the measuring ruler 6 and can extend and retract through the groove on the end face of the sensing base 10. When the movable block contacts the coal pile, it is compressed and retracts, triggering the contact signal of the sensing head 117, while protecting the end of the measuring ruler 6 from direct impact.

[0036] In this embodiment, the display screen 12 and the button frame 13 are located on the outer surface of the measuring instrument 2, making it convenient for operators to observe and operate. The display screen 12 displays real-time measurement data (such as empty floor height, equipment status, etc.), and manual control (such as starting measurement, calibration, etc.) is achieved through the button frame 13.

[0037] In this embodiment, the electrical connection system is built between the measuring instrument 2 and the sensor head 117, and is connected via a wireless module. It transmits the trigger signal from the sensor head 117 to the control unit of the measuring instrument 2, and simultaneously provides power and data communication to the sensor head 117.

[0038] Working principle

[0039] Initialization and Startup: The operator starts the measurement program via button box 13. The drive motor begins to release the measuring tape 9, causing the measuring ruler 6 to extend downwards. Guided by the protective frame 5, the measuring ruler 6 moves vertically downwards, and the sensing head 117 descends accordingly.

[0040] Contact detection: When the sensing head 117 contacts the surface of the coal pile, the movable block is squeezed and retracts into the sensing base 10, triggering a contact signal from the sensing head 117. This signal is transmitted to the control unit of the measuring instrument 2 through the electrical connection system.

[0041] Data recording and processing: The control unit immediately stops the drive motor and records the current extension length of the measuring ruler 6 (i.e., the distance from the installation position of the fixed column 1 to the surface of the coal pile). The actual distance of the empty layer in the coal bunker is calculated using a preset algorithm (e.g., subtracting the height offset of the fixed column 1).

[0042] Results Output and Display: Measurement results are displayed in real time on screen 12, and data export or remote transmission is supported (expandable functionality required). After measurement, the drive motor automatically retracts the measuring scale 6, awaiting the next measurement command.

[0043] Protection mechanisms: The protective frame 5 prevents coal dust from blocking the path of the measuring ruler 6; the movable block structure prevents the end of the measuring ruler 6 from being damaged by impact; and the telescopic component 4's retractable box 8 ensures that the measuring ruler 6 remains neat and compactly stored when not in use.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
