[0029] In order to make the technical scheme of the present application better understood by the people in the art, the technical scheme of the present application will be described clearly and completely below in combination with the drawings of the present application. Based on the embodiments in the present application, other similar embodiments obtained by the people in the art without making creative efforts should all belong to the scope of protection of the present application. In addition, the direction words mentioned in the following embodiments, such as “up”, “down”, “left”, “right”, etc. are only the directions of the drawings, therefore, the direction words used are used to explain but not to limit the present application.

[0030] The utility model is further described below in combination with the drawings and preferred embodiments.

[0031] Please refer to Figures 1-7 The embodiment provides a protective device of a coal machine LORA wireless temperature measurement and collection module, which is installed on a rocker arm of a coal machine 6 and used for protecting the LORA wireless temperature measurement and collection module 1 on the rocker arm of the coal machine 6. The protective device comprises:

[0032] A protective plate 2 is fixedly arranged on a traction shell 3 of the coal machine and used for protecting the LORA wireless temperature measurement and collection module 1.

[0033] A support structure is fixedly arranged on the protective plate 2 and used for providing a support and fixing point of the LORA wireless temperature measurement and collection module 1 on the protective plate 2.

[0034] Please refer to Figure 1 and Figure 5 In some specific embodiments, the protective plate 2 can be fixedly arranged on the traction shell 3 of the coal machine by welding or bolts, as shown in Figure 5 or Figure 6 The position of the red circle is the installation position of the protective device. Since the movement of the coal machine 6 is relatively complex at the hinged position of the rocker arm of the coal machine 6, the relative movement between various components is frequent, and there is a great risk of collision, the protective plate 2 can effectively isolate the influence of the external environment on the LORA wireless temperature measurement and collection module 1, directly block the impact force from the external coal block impact, equipment component collision and the like, protect the LORA wireless temperature measurement and collection module 1 from physical damage, the support structure provides a support and fixing point for the LORA wireless temperature measurement and collection module 1, also plays a buffering and stabilizing role between the protective plate 2 and the LORA wireless temperature measurement and collection module 1, even if the protective plate 2 is impacted to a certain extent, the support structure can disperse the impact force, prevent the LORA wireless temperature measurement and collection module 1 from loosening or being damaged due to sudden vibration or collision. To a great extent, the probability of damage of the LORA wireless temperature measurement and collection module 1 is reduced, and the repair and replacement work due to damage of the LORA wireless temperature measurement and collection module 1 is reduced, which not only saves the repair cost, but also avoids the downtime of the coal machine 6 due to module failure, and improves the production efficiency.

[0035] Please refer to Figure 1The LORA wireless temperature measurement collection module 1 is fixedly connected with one side of the protection plate 2 through the support structure, which can ensure the accurate position of the LORA wireless temperature measurement collection module 1 in the protection device. During the operation of the coal machine 6, especially when the rocker arm moves at the hinged position, vibration and shaking may occur. This accurate fixing mode can prevent the LORA wireless temperature measurement collection module 1 from affecting its normal temperature measurement function due to position deviation, and ensure the accuracy of the temperature collection point. At the same time, the support structure also plays the role of a bridge, tightly connecting the LORA wireless temperature measurement collection module 1 and the protection plate 2 together, uniformly transmitting the external force received by the LORA wireless temperature measurement collection module 1 to the protection plate 2, and the protection plate 2 can also disperse the force to the traction shell 3 of the coal machine. This force transmission and dispersion mechanism enhances the stability of the entire protection device and the LORA wireless temperature measurement collection module 1 at the hinged position of the rocker arm of the coal machine 6, greatly reducing the risk of loosening and damage of the LORA wireless temperature measurement collection module 1 due to instability.

[0036] Referring to Figures 1-4 The support structure includes two BOSS blocks 4 of the same size, which makes the LORA wireless temperature measurement collection module 1 more evenly stressed when connected with the protection plate 2, greatly improving the stability of the LORA wireless temperature measurement collection module 1.

[0037] Specifically, the two sides of the LORA wireless temperature measurement collection module 1 are fixedly connected with the protection plate 2 through a BOSS block 4 respectively.

[0038] It can be understood that, referring to Figures 3-4 The two sides of the LORA wireless temperature measurement collection module 1 can be fixedly connected with the BOSS block 4 through bolts respectively, and then fixedly connected with the protection plate 2, further enhancing the stability of the connection structure of the LORA wireless temperature measurement collection module 1 and the protection plate 2.

[0039] Referring to Figure 2 The other side of the protection plate 2 is provided with a through hole 5 for avoiding the antenna end of the LORA wireless temperature measurement collection module 1. The antenna is a key component for wireless signal transmission of the LORA wireless temperature measurement collection module 1, and the through hole 5 provided on the protection plate 2 can ensure that the antenna end is not blocked by the protection plate 2, reduce signal attenuation, improve signal transmission distance and quality, so as to ensure that temperature data can be accurately and stably transmitted to the receiving end, and improve the accuracy and reliability of signal transmission.

[0040] Specifically, the protection plate 2 is a high-strength steel plate.

[0041] Referring to Figure 4In some specific embodiments, the protective plate 2 is a high-strength steel plate, so that in the complex and impact-prone environment of the rocker hinge of the coal machine 6, it can effectively resist the impact of coal blocks, collisions between equipment components, and other external impact forces, thereby protecting the LORA wireless temperature measurement and collection module 1. The high-strength steel plate can withstand pressure, ensuring the integrity of the protective plate 2 and preventing it from bending or breaking due to excessive pressure, providing stable protection for the internal LORA wireless temperature measurement and collection module 1. At the same time, as shown in Figure 4 , the part of the protective plate 2 fixedly connected with the traction shell 3 of the coal machine has an arc-shaped design, which can effectively reduce the direct impact of coal blocks on the protective plate 2, thereby further prolonging the service life of the protective plate 2.

[0042] Specifically, the protective plate 2 is rectangular in shape.

[0043] Specifically, the length of the protective plate 2 is 280 mm, the width is 275 mm, and the thickness is 20 mm.

[0044] In some specific embodiments, referring to Figures 2-3 , the shape and size of the protective plate 2 are designed to adapt to the coal machine 6 equipment. The protective plate 2 is overall rectangular in shape, and is 280 mm long and 275 mm wide in size to fit the installation size and protective properties of the equipment. The protective plate 2 can provide a relatively comprehensive coverage range at the rocker hinge of the coal machine 6, effectively shielding potential threats from all directions and ensuring that the LORA wireless temperature measurement and collection module 1 is within its protection range. In addition, a cutout can be designed on two adjacent corners of the protective plate to make it more aesthetically pleasing. Furthermore, a thickness of 20 mm ensures the strength of the protective plate 2 while also meeting the spatial layout requirements of the entire protective device. This thickness is sufficient to resist a certain degree of external impact without occupying too much internal space of the coal machine 6 and affecting the normal operation of other equipment.

[0045] Specifically, the LORA wireless temperature measurement and collection module 1 is installed on the lower surface 7 of the protective plate.

[0046] Specifically, the through hole 5 is provided on the upper surface 8 of the protective plate.

[0047] Referring to Figures 5-7In some specific embodiments, the LORA wireless temperature measurement and collection module 1 is installed on the lower surface 7 of the protective plate, that is, the side of the protective plate 2 on which the LORA wireless temperature measurement and collection module 1 is installed faces the inside of the coal machine 6, which means that the module can effectively monitor the temperature change inside the coal machine 6 and transmit data out; the through hole 5 is arranged on the upper surface 8 of the protective plate, that is, the side of the protective plate 2 on which the through hole 5 is arranged faces the outside of the coal machine 6, which is conducive to signal transmission by the antenna of the LORA wireless temperature measurement and collection module 1, and the antenna can send temperature data to the receiving end of the LORA wireless temperature measurement and collection module 1 through the through hole 5 on the protective plate 2 without obstruction, avoiding signal obstruction by the protective plate 2, reducing signal attenuation and reflection interference, and improving the distance and quality of wireless signal transmission.

[0048] It should be noted that the embodiment provides a protective device for a LORA wireless temperature measurement and collection module of a coal machine, which is installed on a swing arm of the coal machine and used for protecting the LORA wireless temperature measurement and collection module on the swing arm of the coal machine. The protective device comprises a protective plate fixedly arranged on a traction shell of the coal machine and used for protecting the LORA wireless temperature measurement and collection module, and a support structure fixedly arranged on the protective plate and used for providing a support and fixing point for the LORA wireless temperature measurement and collection module on the protective plate. The technical problem that there is no protective device capable of effectively protecting the LORA wireless temperature measurement and collection module on the swing arm of the coal machine in the prior art is solved. Meanwhile, a through hole is arranged on the protective plate, so that the protective device provided by the embodiment can provide effective protection for the LORA wireless temperature measurement and collection module while ensuring the quality of communication signals, greatly improves the safety and reliability of the coal machine equipment, greatly reduces the maintenance cost of the coal machine equipment, and further improves the production efficiency of the equipment.

[0049] The technical features described above can be combined in any manner. Although not all possible combinations of the technical features are described, any combination of the technical features should be considered to be covered by the present specification, as long as such a combination does not result in a contradiction.
