Description

Technical Field

[0001] This utility model relates to the field of coal detection technology, specifically to a laser coal flow detection device. Background Technology

[0002] In coal mining and transportation, accurate detection of coal flow is crucial for efficient production and safety. Laser coal flow detection devices, as advanced detection equipment, utilize laser cameras to precisely acquire relevant information about coal flow, such as flow rate, velocity, and distribution, thus providing reliable data support for the automated control and management of coal mine production.

[0003] Traditional laser coal flow detection devices typically consist of a housing and a laser camera installed inside. However, in actual use, the laser camera generates a significant amount of heat during prolonged operation. If heat cannot be dissipated effectively and promptly, the device temperature will become excessively high, affecting its performance and lifespan, and consequently reducing the accuracy and stability of the detection device. Furthermore, the coal mine production environment is usually filled with large amounts of dust and other particulate matter. These particles can easily enter the detection device's housing through the heat dissipation channels, adhering to the laser camera's lens or other critical components, interfering with laser emission and reception, affecting image acquisition quality, and leading to inaccurate detection results. Moreover, long-term accumulation of dust can damage internal electronic components, increasing the equipment's failure rate and maintenance costs.

[0004] While some existing technologies may use cooling fans to cool laser cameras, they lack effective dust prevention measures, making it difficult to ensure heat dissipation while preventing external particles from entering the device. Even with dust prevention measures, such as simple dust filters, a large amount of dust accumulates on the filters after prolonged use, affecting ventilation and heat dissipation. When a large amount of dust accumulates, the dust filter needs to be disassembled for cleaning and then reinstalled, a cumbersome and inconvenient process.

[0005] Therefore, there is an urgent need for a laser coal flow detection device that can effectively cool the laser camera, prevent external particles from entering the equipment, and facilitate the cleaning of dustproof components to maintain good ventilation and heat dissipation performance. Utility Model Content

[0006] In view of this, the present invention provides a laser coal flow detection device, which can not only cool the laser camera through the heat dissipation mechanism, but also block dust particles through the dustproof component in the heat dissipation mechanism, and regularly clean the dustproof screen to avoid affecting the ventilation and heat dissipation effect.

[0007] To address the aforementioned technical problems, this utility model provides a laser coal flow detection device, comprising a housing, inside which a laser camera is mounted via a fixing block. The rear of the housing is equipped with a heat dissipation mechanism for cooling the laser camera. The heat dissipation mechanism includes a fixed frame installed at the rear of the housing, within which a cooling fan is fixedly mounted. A dustproof component is provided on one side of the cooling fan to prevent external particles from entering the housing. In other words, the heat dissipation mechanism cools the laser camera, preventing heat buildup during prolonged operation that could lead to performance degradation or damage. This ensures stable operation of the laser camera in a suitable temperature environment, thereby improving the detection accuracy and reliability of the laser coal flow detection device. Furthermore, the dustproof component prevents external particles from entering the housing, reducing the corrosion of the laser camera by dust and other impurities, lowering the possibility of dust adhering to the camera lens or internal components affecting detection results, and extending the device's service life.

[0008] The dustproof assembly includes a dustproof net installed at an angle within a fixed frame. Two sets of drive sources are symmetrically arranged on one side of the dustproof net to control its sliding. That is, the drive sources control the dustproof net to slide, changing its position so that dust adhering to the net can fall off during the sliding process, preventing dust accumulation from affecting ventilation and heat dissipation, and further improving the cleanliness of the equipment's interior.

[0009] Each drive unit includes two symmetrically arranged grooves within a fixed frame. A slider is slidably mounted within each groove, and the slider is connected to the dust screen via a connecting rod. That is, the slider slides within the groove and connects to the dust screen via the connecting rod, ensuring that the power from the drive unit is stably and accurately transmitted to the dust screen. This makes the sliding process of the dust screen smoother, improving the operational stability of the equipment. This simple connection method facilitates easy manufacturing and maintenance, reducing production costs and maintenance difficulty.

[0010] Each drive source also includes a micro motor for providing power. The micro motor is located at the bottom of the fixed frame, and its output shaft passes through two slide grooves. Two eccentric wheels are symmetrically mounted on the output shaft, and both eccentric wheels rotate within the slide grooves via the output shaft. The slider is equipped with abutment blocks that abut against the eccentric wheels. In other words, by using the micro motor as a power source, in conjunction with the eccentric wheels and abutment blocks, the dust filter can be automatically adjusted. It can automatically adjust the dust filter according to a preset program or actual conditions, improving the intelligence and ease of use of the equipment.

[0011] A reset component is fixed on the slide rail to pull the slider back. That is, the reset component pulls the slider back to its initial position, allowing the drive source to work cyclically. This ensures the dust filter continuously slides and adjusts according to the set pattern, effectively performing its dustproof and self-cleaning functions, improving the equipment's efficiency and stability. Furthermore, the reset operation ensures that the slider's starting position is consistent each time it slides, guaranteeing the accuracy of the dust filter adjustment and making the equipment's operation more precise and reliable.

[0012] The reset assembly includes a fixed plate mounted on the slide groove and a vertical plate mounted on the slider. A slide rod is mounted on the vertical plate, passing through the fixed plate and connected at its end to a limiting block. A reset spring connects the limiting block and the fixed plate. That is, by utilizing the elasticity of the reset spring, the slider can be smoothly pulled back to its initial position, avoiding impact and vibration during the slider's return process, reducing damage to the equipment structure, and extending the equipment's service life.

[0013] The dustproof net is sloped downwards and equipped with a baffle to prevent dust backflow. This baffle further enhances the dustproof effect, effectively preventing dust backflow and preventing dust already blocked outside the dustproof net from re-entering the equipment. This reduces dust accumulation around the equipment, improves the internal environment, lowers the risk of dust-related malfunctions, and enhances the overall performance and stability of the equipment.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. External air is drawn into the housing by a cooling fan to replace internal heat, keeping the laser camera within a suitable operating temperature range, ensuring stable operation of the equipment, and improving the reliability and detection accuracy of the laser coal flow detection device.

[0016] 2. The dustproof net effectively blocks external coal particles, providing a relatively clean working environment for the laser camera, extending the service life of the equipment, and reducing maintenance costs.

[0017] 3. The micro motor drives the eccentric wheel to rotate, and the eccentric wheel abuts against the abutting block on the slider, causing the slider to slide in the slide groove, which in turn drives the dustproof net to slide. At the same time, the reset component on the slide groove will pull the slider back, causing the dustproof net to vibrate. The vibration can shake off the dust attached to the dustproof net, avoid the dustproof net from clogging, ensure the air permeability and dustproof effect of the dustproof net, and thus continuously and effectively prevent dust from entering the inside of the device.

[0018] 4. When the dustproof net vibrates to clean the dust, the baffle can prevent the fallen dust from flowing back to the vicinity of the dustproof net, further improving the dustproof effect, ensuring a clean environment inside the laser coal flow detection device, and ensuring the stable operation of the equipment.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. 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 described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figures 1-5 As shown: This embodiment provides a laser coal flow detection device, including a housing 10. Inside the housing 10, a laser camera 20 is mounted via a fixing block 30. The rear of the housing 10 is provided with a heat dissipation mechanism 40 for cooling the laser camera 20. The heat dissipation mechanism 40 includes a fixing frame 41 fixedly mounted to the rear of the housing 10 by bolts. A cooling fan 42 is fixedly mounted inside the fixing frame 41 via a fan bracket. A dustproof component 43 is provided on one side of the cooling fan 42 to prevent external particles from entering the interior of the housing 10.

[0027] A fixing frame 41 is installed at the rear of the outer casing 10 of the laser coal flow detection device, and a cooling fan 42 is fixed inside the fixing frame 41, so that the cooling fan 42 can cool the laser camera 20, which is located inside the outer casing 10 and is mounted by a fixing block 30. At the same time, a dustproof component 43 is provided on one side of the cooling fan 42 to prevent external particles from entering the interior of the outer casing 10.

[0028] The cooling fan 42 effectively reduces the operating temperature of the laser camera 20, preventing its performance and lifespan from being affected by excessive temperature. The dustproof component 43 protects the laser camera 20 and other internal components of the device, preventing dust and other particles from entering and causing damage, thereby improving the stability and reliability of the device.

[0029] According to one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, the dustproof assembly 43 includes a dustproof net 431 installed obliquely within a fixed frame 41. Two sets of drive sources 44 for controlling the sliding of the dustproof net 431 are symmetrically arranged on one side of the dustproof net 431. Each drive source 44 includes two sliding grooves 441 fixedly installed at the top and bottom of the fixed frame 41 by screws. A slider 442 is slidably installed in each groove 441, and the slider 442 is connected to the dustproof net 431 via a connecting rod 443 and a fixing washer. Each drive source 44 also includes... A micro motor 444 is used to provide power. The micro motor 444 is mounted on the bottom of the fixed frame 41 by a motor bracket. The output shaft 445 of the micro motor 444 passes through two slides 441 and its end is connected to the fixed frame 41 by a bearing. Two eccentric wheels 446 are symmetrically mounted on the output shaft 445 by a fixing pin. Both eccentric wheels 446 rotate in the slides 441 through the output shaft 445. An abutment block 447 that abuts against the eccentric wheels 446 is welded on the slider 442.

[0030] The inclined installation of the dustproof net 431 increases the difficulty of dust adhesion, making it easier for dust to slide off. At the same time, the drive source 44 controls the sliding of the dustproof net 431, and the dustproof net 431 is cleaned or its position is adjusted regularly to maintain a good dustproof effect and further improve the dustproof capability of the device.

[0031] According to another embodiment of the present invention, such as Figure 3 and Figure 4As shown, a reset assembly 45 for pulling back the slider 442 is fixed on the slide groove 441. The reset assembly 45 includes a fixed plate 451 and a vertical plate 452 that are respectively fixed to the slide groove 441 and the slider 442 by welding. A slide rod 453 is connected to the vertical plate 452 through a threaded hole. The slide rod 453 passes through a through hole on the fixed plate 451 and is connected to a limiting block 454 by a thread at its end. A reset spring 455 is connected between the limiting block 454 and the fixed plate 451.

[0032] When slider 442 slides, slide rod 453 slides within fixed plate 451, and return spring 455 is stretched or compressed. When the external force disappears, the elastic force of return spring 455 returns slider 442 to its initial position.

[0033] The reset component 45 enables the dustproof net 431 to automatically return to its initial position after the sliding operation is completed, ensuring the normal working condition of the dustproof net 431, and also improving the automation level and ease of operation of the device.

[0034] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a baffle 46 is inclined below the dustproof net 431 to prevent dust from flowing back.

[0035] The dustproof effect of the device is further enhanced by the baffle 46. The inclined baffle 46 can prevent dust that has been blocked and slid off by the dustproof net 431 from flowing back into the device, effectively preventing secondary pollution by dust and improving the dustproof performance of the device.

[0036] The method of using this utility model is as follows: While the laser camera 20 is working, the cooling fan 42 is started. The fan accelerates airflow, dissipating the heat generated by the laser camera 20 inside the housing 10. As the cooling fan 42 rotates, dust enters the housing 10 with the airflow. This dust is blocked by a dustproof net 431 installed at an angle within the fixed frame 41. While the dustproof net 431 blocks particles from the outside air, the micro motor 444 is started. The output shaft 445 of the micro motor 444 drives the eccentric wheel 446 to rotate. The eccentric wheel 446 abuts against the abutting block 447 on the slider 442, causing the slider 442 to slide within the groove 441. The slider 442 drives the dustproof net 431 to slide via the connecting rod 443, causing the dustproof net 431 to vibrate and shake off the dust adsorbed on the dustproof net 431. When the eccentric wheel 446 rotates and causes the slider 442 to slide, the reset spring 455 in the reset assembly 45 will be stretched or compressed. When the eccentric wheel 446 continues to rotate and no longer pushes the slider 442, the elastic force of the reset spring 455 will pull the slider 442 back to the initial position.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
