Description

Technical Field

[0001] This utility model relates to the field of coal bunker volume detection technology, and in particular to a coal bunker volume detection device. Background Technology

[0002] Coal bunker volume detection mainly refers to measuring the height of coal inside the bunker using tools such as radar level gauges, and then calculating the real-time coal loading volume. This is crucial for coal mines, enabling accurate inventory management, optimized production and transportation scheduling, and effective prevention of production stoppages, equipment damage, and even safety accidents caused by empty or overflowing bunkers. It is a core management link ensuring continuous, stable, safe, and efficient production and operation of coal mines. A coal bunker volume detection device is required when detecting the volume of coal bunkers.

[0003] Current technology primarily relies on level instruments to detect the volume of coal bunkers, with radar level instruments being widely used due to their resistance to dust and harsh environments. They transmit microwave pulses into the material inside the bunker via an antenna and receive the echoes, determining the material level by precisely calculating the beam's flight time. During installation, to avoid obstructions within the bunker and ensure the beam is accurately reflected to the center of the material surface, the detection angle must be finely adjusted; therefore, universal flanges are commonly used for installation. These flanges mainly consist of a ball joint structure, upper and lower flanges, and multiple locking bolts, allowing for flexible angle deflection via the ball joint. However, when adjusting the angle of the level gauge via the universal flange, several locking bolts must first be completely loosened, allowing the level gauge to swing freely within the flange along with the ball joint. After adjusting it to the appropriate angle, the operator must continuously hold the radar level gauge with one hand to maintain angle stability, while the other hand must tighten several bolts sequentially to secure it. If this operation is performed by only one person, it is difficult to maintain stable support of the level gauge while tightening the bolts, which can easily lead to deviation of the adjusted angle of the level gauge; if two people cooperate to operate, although the stability problem can be solved, it results in wasted manpower and low efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a coal bunker volume detection device to address the problem that traditional radar level gauges are inconvenient to adjust the angle.

[0005] A coal bunker volume detection device includes: a level instrument, a flange at the bottom of the level instrument, and a ball joint mechanism between the flange and the radar level instrument. The pre-fixing mechanism includes two fixing components disposed inside the flange, the two fixing components being disposed opposite each other on both sides of the ball joint mechanism, and a snap-fit ​​component mounted on the flange surface being disposed above the fixing components.

[0006] In one embodiment, the fixing component includes a threaded rod disposed on the side of the flange, one end of the threaded rod passing through the flange and the other end rotatably connected to an adjusting block.

[0007] In one embodiment, the adjusting block is slidably connected to the inner wall of the flange, and a fixing block is provided on the side of the adjusting block away from the threaded rod, and a rubber pad is fixedly connected to the inner side of the fixing block.

[0008] In one embodiment, two sliding rods are fixedly connected to the outside of the fixed block. The sliding rods pass through the adjusting block and are slidably connected to the adjusting block. A spring is fixedly connected between the fixed block and the adjusting block, and the spring is sleeved on the surface of the sliding rod.

[0009] In one embodiment, the snap-fit ​​assembly includes a service cover disposed on the flange surface, the service cover being mounted to the flange surface by a plurality of bolts.

[0010] In one embodiment, a connecting rod is fixedly connected to the upper surface of the fixing block. The connecting rod is L-shaped, and the end of the connecting rod away from the fixing block extends to the bottom of the maintenance cover.

[0011] In one embodiment, a lever is slidably connected to the end of the connecting rod away from the fixing block, and a strip-shaped opening is provided in the middle of the maintenance cover, with the lever disposed within the strip-shaped opening.

[0012] In one embodiment, the maintenance cover has multiple slots on one side of the strip-shaped opening, and the slots are used in conjunction with a lever.

[0013] Beneficial effects 1. By setting a fixing component and a snap-fit ​​component between the flange and the ball joint structure, a quick and brief pre-fixation can be performed on the level instrument after the angle adjustment is completed. This allows the staff to perform the subsequent final tightening operation with ease and accuracy. This not only reduces the risk of angle deviation caused by the high difficulty of operation, but also achieves the goal of a single person to complete all the adjustment work efficiently and accurately. It also significantly improves the installation efficiency and reliability. 2. By setting a threaded rod in conjunction with an adjusting block, the fixing components can be adjusted as a whole, thereby indirectly adjusting the spring tension. This adjusts the clamping force of the fixing block on the ball joint when pre-fixing it, allowing workers of different physical abilities to adjust the spring to the most suitable strength according to their own situation. This ensures that all workers can complete the installation work with almost the same efficiency and safety, increasing the ease of use of the device. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figure 1 - Figure 5 This invention describes a coal bunker volume detection device.

[0019] In one embodiment, a coal bunker volume detection device, such as Figure 1 As shown, the coal bunker volume detection device of this embodiment includes: a level instrument 100, a flange 200 at the bottom of the level instrument 100, and a ball joint mechanism 210 between the flange 200 and the radar level instrument 100. The pre-fixing mechanism 300 includes two fixing components 310 disposed inside the flange 200. The two fixing components 310 are disposed opposite to each other on both sides of the ball joint mechanism 210. A snap-fit ​​component 320 is disposed above the fixing components 310 and mounted on the surface of the flange 200.

[0020] It should be noted that the level gauge 100 in this device is a radar level gauge 100, model TC-FMCE15F-X2, which mainly consists of core components such as a horn antenna, a high-frequency microwave transceiver module, and a signal processing unit. When detecting the volume of the coal bunker, the antenna transmits microwave pulses into the coal bunker and receives the echoes reflected from the surface of the coal pile. The signal processing unit accurately calculates the microwave round-trip time and then calculates the distance from the antenna to the coal surface based on the wave velocity. The real-time material level height is obtained by subtracting this distance value from the preset total height of the bunker. Finally, the corresponding coal storage volume is calculated based on the precise geometric dimensions of the bunker. The ball joint mechanism 210 mainly consists of a universal ball installed at the bottom of the level instrument 100 and a fixed ring installed above the flange 200. The universal ball is located in the middle of the flange 200 and can rotate, while the fixed ring is located in the upper part of the universal ball through a positioning hole opened on the surface of the flange 200 by bolts. By rotating the bolts, the fixed ring moves closer to the surface of the flange 200, thereby increasing the pressure of the fixed ring on the middle part of the universal ball. The friction between the fixed ring and the universal ball fixes the universal ball, thereby fixing the angle of the level instrument 100.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 310 includes a threaded rod 311 disposed on the side of the flange 200. One end of the threaded rod 311 passes through the flange 200, while the other end is rotatably connected to an adjusting block 312. The adjusting block 312 is slidably connected to the inner wall of the flange 200. A fixing block 313 is disposed on the side of the adjusting block 312 away from the threaded rod 311. A rubber pad is fixedly connected to the inner side of the fixing block 313. Two sliding rods 315 are fixedly connected to the outer side of the fixing block 313. The sliding rods 315 pass through the adjusting block 312 and are slidably connected to the adjusting block 312. A spring 314 is fixedly connected between the fixing block 313 and the adjusting block 312, and the spring 314 is sleeved on the surface of the sliding rod 315.

[0022] In this embodiment, when the worker needs to adjust the tension of the spring 314 according to their physical condition, they directly rotate the threaded rod 311. The threaded rod 311 drives the adjusting block 312 to move on the inner wall of the flange 200, thereby changing the distance between the adjusting block 312 and the universal ball, thus adjusting the extension length of the spring 314 to control the preload of the spring 314. Since the spring 314 is always in a compressed state no matter how it is adjusted, and the fixing block 313 is also in contact with the universal ball without interference, the preload of the spring 314 decreases as the adjusting block 312 gets closer to the universal ball. The larger the size of the bolt, the greater the force required to pull the lever 323. However, this also leads to a more stable pre-fixation of the omnidirectional ball, and vice versa. It should be noted that the pre-fixation effect of the pre-fixation mechanism 300 on the omnidirectional ball is related to the pre-tightening force of the spring 314. The pre-fixation mechanism 300 is only to allow the operator to focus more on tightening multiple bolts, thereby increasing the installation speed. During this process, the operator still needs to provide a certain amount of support for the level gauge 100. The pre-tightening force of the fixing block 313 makes it difficult for the omnidirectional ball to move, thereby reducing the difficulty of providing support. It should be noted that the pre-fixing mechanism 300 of this device is located inside the flange 200 and will not affect the mounting holes of the flange 200 or the mounting holes of the ball joint mechanism 210. Therefore, it will not affect the normal connection and function of the flange 200 and the ball joint mechanism 210.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the snap-fit ​​assembly 320 includes a maintenance cover 321 disposed on the surface of the flange 200, which is mounted to the surface of the flange 200 by multiple bolts. A connecting rod 322 is fixedly connected to the upper surface of the fixing block 313. The connecting rod 322 is L-shaped, and the end of the connecting rod 322 away from the fixing block 313 extends to the bottom of the maintenance cover 321. A lever 323 is slidably connected to the end of the connecting rod 322 away from the fixing block 313. A strip-shaped opening is provided in the middle of the maintenance cover 321, and the lever 323 is disposed in the strip-shaped opening. Multiple slots 324 are provided on one side of the strip-shaped opening of the maintenance cover 321, and the slots 324 cooperate with the lever 323.

[0024] In this embodiment, the maintenance cover 321 is bolted to the surface of the flange 200. Since the rubber gasket is a consumable, the staff needs to replace the rubber gasket regularly and facilitate the maintenance of the pre-fixing mechanism 300. The outer part of the threaded rod 311 is fitted with a rubber sleeve, and two rubber pieces are provided below the slot 324 at the strip opening of the maintenance cover 321. The rubber pieces cover the part other than the lever at the strip opening, thereby preventing airborne debris from entering the flange 200 and affecting the threaded rod 311 and other components.

[0025] Working principle: When the level gauge 100 needs to be adjusted, the operator first needs to pull the lever 323 and insert the lever 323 into the slot 324. The lever 323 drives the fixed block 313 to move away from the universal ball through the connecting rod 322 and compresses the spring 314. At this time, the fixed block 313 is not in contact with the universal ball, and the spring 314 is in a compressed state. Then, by loosening the ball joint mechanism 210, the level gauge 100 moves in the middle of the flange 200. Then, the operator directly adjusts the level gauge 100 to a suitable angle. Then, the operator needs to tighten the ball joint mechanism 210 by rotating multiple bolts to tighten the ball joint mechanism 210. Prior to this, the staff directly disengaged the two locking blocks from the slot 324 by moving the two locking blocks. The fixing block 313 was only pushed by the spring 314. At this time, the spring 314 pushed the fixing block 313 to move towards the ball joint and made the rubber pad fit tightly against the ball joint. By increasing the friction between the fixing block 313 and the ball joint, the ball joint was fixed. At this time, the staff could quickly tighten multiple bolts and completely fix the angle of the level instrument 100 through the ball joint mechanism 210.

[0026] It should be noted that the level gauge 100, spring 314, threaded rod 311, flange 200 and ball joint mechanism 210 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the level gauge 100 can be powered by the built-in power supply. The specific power supply method can be selected according to the situation, which will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
