Description

Technical Field

[0001] This utility model relates to the field of coal quantity detection technology, specifically to an explosion-proof coal quantity detection device for mining. Background Technology

[0002] The main functions of coal quantity detection devices do include real-time monitoring, measurement, and control of coal weight or flow rate. Through accurate coal quantity monitoring, production processes can be optimized, reducing downtime or production delays caused by inaccurate coal quantity estimation. By detecting the amount of coal in real time, the storage or transportation status of coal can be understood at any time, facilitating timely adjustments to inventory and logistics plans. This helps enterprises or mines accurately grasp the coal inventory situation, provides data support for production scheduling, and allows for reasonable production planning based on coal inventory status, thereby improving production efficiency.

[0003] Chinese Patent Publication No. CN217465919U, entitled "A Coal Bunker Coal Quantity Detection Device," includes a coal bunker coal quantity detection system. The coal bunker coal quantity detection system comprises a radar level gauge body, an antenna horn, and a flange. When the radar level gauge body of the coal bunker coal quantity detection device is impacted by an object, when it impacts one side of one of the anti-collision plates, the force generated by the impact presses the anti-collision plate downwards, causing an elastic steel plate to press down on a slider, thereby causing a spring to stretch. Simultaneously, it causes another elastic steel plate to bend and compress against each other. During the deformation process of the spring and the first elastic steel plate, the force generated by the impact is continuously absorbed and decomposed, providing anti-collision protection for the protective cover and protecting the internal instruments from damage, reducing damage to the radar level gauge body and lowering the user's maintenance costs.

[0004] The shortcomings of the above solution are as follows: Although the solution can detect coal quantity, it relies on radar for monitoring. Radar systems are sensitive to environmental conditions, and factors such as temperature and humidity may interfere with the propagation of radar waves, thus affecting measurement accuracy. Furthermore, the solution cannot protect and store the device, and environmental factors such as rain may cause damage or performance degradation to the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a mine explosion-proof coal quantity detection device to solve the technical problems of existing technology that uses radar for monitoring. However, radar systems are sensitive to environmental conditions, and factors such as temperature and humidity may interfere with the propagation of radar waves, thereby affecting the measurement accuracy. Furthermore, the above solutions cannot protect and store the device, and environmental factors such as rain may cause damage or performance degradation to the equipment.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] Explosion-proof coal quantity detection device for mining, including installation platform;

[0008] The mounting platform is fixedly connected to two sides by rotating motors. Each rotating motor has a rotating plate fixedly connected to its rotating end, and a rotating rod fixedly connected to the rotating plate. The ends of two rotating rods furthest from the rotating plate are connected to a mounting plate. The mounting plate has two sets of slide rails. A mounting frame is mounted above the mounting plate, and multiple detectors are fixedly connected to the mounting frame. An adjustment mechanism is connected between the mounting frame and the mounting plate. The adjustment mechanism includes two adjusting rods. Two sets of sliders are slidably connected to the mounting plate, and a double-headed telescopic rod is fixedly connected between the two sets of sliders. The sliders cooperate with the slide rails. Connecting blocks are fixedly connected to both sides of the mounting frame. The adjusting rods are rotatably connected between the connecting blocks and the sliders. A second hinge connects the connecting blocks and the adjusting rods, and a first hinge connects the sliders and the adjusting rods. Two sets of protective mechanisms are connected to the sides of the mounting platform.

[0009] As a further embodiment of this utility model, the mounting plate is a smooth flat plate.

[0010] As a further embodiment of this invention, multiple detectors are equidistantly arranged on the mounting bracket.

[0011] As a further embodiment of this invention, the detector is an ultrasonic coal quantity detector.

[0012] As a further embodiment of this utility model, both adjusting rods are steel structures.

[0013] As a further embodiment of this invention, the slider has a T-shaped structure.

[0014] As a further embodiment of this utility model: each set of protective mechanisms includes a side frame and a sliding plate. The side frame is fixedly connected to both sides of the installation platform. A through groove is provided on the side frame. The sliding plate is slidably connected to the side frame through the through groove. A vertical through hole is provided on the side frame. The vertical through hole is configured to cooperate with the rotating rod.

[0015] As a further embodiment of this utility model, a waterproof membrane is laid on the outer periphery of the side frame.

[0016] As a further embodiment of this invention, a handle is connected to the sliding plate.

[0017] As a further aspect of this utility model, the handle is provided with anti-slip textures.

[0018] The beneficial effects of this utility model are:

[0019] 1. The propagation speed of ultrasonic waves in coal varies depending on factors such as coal density and moisture content. By measuring the propagation time of ultrasonic waves, the thickness or volume of the coal can be calculated. The extension and retraction of the double-headed telescopic rod drives two sliders to move. The sliders slide on the slide rail, which in turn drives the adjusting rod for adjustment. When the adjusting rod slides through the sliders, it can adjust the height of the mounting frame. By precisely adjusting the height of the mounting frame, the ultrasonic sensor can be kept at a consistent distance from the coal surface, thereby improving measurement accuracy. For coal layers of different thicknesses, the sensor position can be quickly adjusted through the adjusting device to adapt to the measurement needs of different layer thicknesses.

[0020] 2. This utility model uses a double-headed telescopic rod to extend and drive the slider to slide towards both ends of the mounting plate, moving the mounting bracket closer to the mounting plate. The handle drives the sliding plate to slide in the through groove, opening the sliding plate. The rotating end of the rotating motor drives the rotating plate to rotate, and the rotating plate drives the mounting plate to rotate through the rotating rod, rotating the mounting plate into the side frame. Pushing the sliding plate, the detector is stored in the side frame, preventing the detector from being directly exposed to the outside in rainy weather and affecting the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-3 As shown, the explosion-proof coal quantity detection device for mining includes an installation platform 1. Rotary motors are fixedly connected to both sides of the installation platform 1. A rotating plate 10 is fixedly connected to the rotating end of each rotating motor. A rotating rod 9 is fixedly connected to the rotating plate 10. The ends of two rotating rods 9 away from the rotating plate 10 are connected to a common mounting plate 11. The mounting plate 11 is a smooth flat plate with two sets of slide rails 7. A mounting frame 16 is installed above the mounting plate 11. Multiple detectors 17 are fixedly connected to the mounting frame 16, and the detectors 17 are equidistantly arranged on the mounting frame 16. The detectors 17 are ultrasonic coal quantity detectors. The mounting bracket 16 is connected to the mounting plate 11 by an adjustment mechanism. The adjustment mechanism includes two adjustment rods 14, both of which are steel structures. Two sets of sliders 12 are slidably connected to the mounting plate 11. A double-headed telescopic rod 3 is fixedly connected between the two sets of sliders 12. The sliders 12 are T-shaped and are configured to cooperate with the slide rail 7. Connecting blocks 15 are fixedly connected to both sides of the mounting bracket 16. The adjustment rods 14 are rotatably connected between the connecting blocks 15 and the sliders 12. A second hinge 19 is connected between the connecting blocks 15 and the adjustment rods 14. A first hinge 18 is connected between the sliders 12 and the adjustment rods 14.

[0028] The installation platform 1 is connected to two sets of protective mechanisms on its side. Each set of protective mechanisms includes a side frame 2 and a sliding plate 5. The side frame 2 is fixedly connected to both sides of the installation platform 1. A waterproof membrane is laid on the outer periphery of the side frame 2. A through groove 4 is opened on the side frame 2. The sliding plate 5 is slidably connected to the side frame 2 through the through groove 4. A vertical through hole 20 is opened on the side frame 2.

[0029] The working principle of this utility model is as follows: Multiple ultrasonic coal quantity detectors 17 measure the amount of coal by emitting ultrasonic waves and receiving the reflected waves. The propagation speed of ultrasonic waves in coal varies due to factors such as coal density and moisture content. By measuring the propagation time of ultrasonic waves, the thickness or volume of coal can be calculated. The extension and retraction of the double-headed telescopic rod 3 drives the two sliders 12 to move. The sliders 12 slide on the slide rail 7, driving the adjusting rod 14 for adjustment. When the adjusting rod 14 slides through the sliders 12, it can drive the height of the mounting frame 16 to be adjusted relative to each other. When monitoring is not required, the extension of the double-headed telescopic rod 3 drives the sliders 12 to slide towards both ends of the mounting plate 11, moving the mounting frame 16 closer to the mounting plate 11. The handle 6 drives the sliding plate 5 to slide in the through groove 4, opening the sliding plate 5. The rotating end of the rotating motor drives the rotating plate 10 to rotate. The rotating plate 10 drives the mounting plate 11 to rotate through the rotating rod 9, rotating the mounting plate 11 into the side frame 2. The sliding plate 5 is pushed to store the detector 17 into the side frame 2.
