Description

Technical Field

[0001] This utility model relates to the field of mining communication equipment technology, specifically to an intrinsically safe wireless base station for mining based on WiFi 7. Background Technology

[0002] In the mining environment, communication stability and equipment safety are paramount. As the core equipment of a mine communication system, the performance of wireless base stations directly impacts communication quality. Existing mine wireless base stations mostly employ traditional communication technologies, resulting in insufficient data transmission rates and anti-interference capabilities, failing to meet the high-speed communication demands of modern mines. Furthermore, the complex underground mining environment, characterized by dust, humidity, and vibration, makes existing base stations prone to water and dust ingress, leading to equipment malfunctions. Additionally, their locking mechanisms are poorly designed, and switching operations are cumbersome. Moreover, the installation, fixation, and portability of base stations need improvement.

[0003] WiFi 7 technology has the advantages of high speed, low latency and strong anti-interference ability. Applying it to mine wireless base stations can effectively improve communication quality. However, how to design an intrinsically safe base station structure that is stable, reliable, and easy to operate for the special environment of mines has become an urgent problem to be solved. Utility Model Content

[0004] This invention aims to solve the above-mentioned technical problems by providing an intrinsically safe wireless base station for mining based on WiFi 7.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A WiFi 7-based intrinsically safe wireless base station for mining includes a housing with a top cover connected to the housing via a hinge. The hinge connection allows the top cover to be flexibly flipped, facilitating the inspection and maintenance of the base station's internal components.

[0007] A sealing ring is installed between the top cover and the housing for sealing, which can effectively prevent dust and moisture from entering the equipment and improve the equipment's waterproof and dustproof performance.

[0008] A locking mechanism for opening and closing the top cover is installed on one side of the housing. The locking mechanism can reliably lock the top cover to the housing, ensuring the stability of the sealing effect.

[0009] Both sides of the housing are equipped with connecting joints for connecting optical fibers. The double connecting joint design enables bidirectional connection of optical fibers, improving the reliability and flexibility of communication.

[0010] The locking mechanism includes a locking block one fixedly connected inside the housing and a locking block two hinged to the outside of the upper cover. A locking plate is slidably mounted on the lower end of the locking block two. A limit rod is movably mounted on one side of the locking block one. A limit disc is off-axis mounted on one end of the limit rod. A limit piece is mounted on the end of the limit disc near the limit rod. The locking piece has a through hole for the limit disc to enter and a limit hole for the limit piece to insert. When the upper cover needs to be locked, the locking block two is rotated to align with the locking block one, pushing the locking plate to allow the limit disc to pass through the through hole and the limit piece to insert into the limit hole, thus locking the mechanism. To unlock, the limit rod is pulled to disengage the limit piece from the limit hole, and the locking piece returns to its original position under the action of the adjusting spring, allowing the upper cover to be opened. The operation is convenient and the locking is reliable.

[0011] Preferably, one side of the first locking block has a moving groove for moving with a limiting rod. A locking spring is installed between the side wall of the moving groove and the limiting rod. The locking spring can apply a continuous force to the limiting rod to ensure a tight fit between the limiting piece and the limiting hole and prevent loosening. The lower end of the second locking block has a sliding groove for sliding with a locking piece. An adjusting spring is provided between the inner wall of the sliding groove and the locking piece. The adjusting spring can drive the locking piece to automatically reset when unlocking, improving the convenience of operation.

[0012] Preferably, the through hole has an inverted triangular structure, which facilitates the quick insertion and positioning of the limiting plate and improves the efficiency of the locking operation.

[0013] Preferably, the outer side of the top cover is folded inward to form a rectangular structure, a support plate is installed on the inner side of the upper end of the housing, and the sealing ring is installed between the rectangular structure and the support plate. The cooperation between the rectangular structure and the support plate can reliably position the sealing ring, ensuring the sealing effect of the sealing ring, and at the same time improving the structural stability of the connection between the top cover and the housing.

[0014] Preferably, the front of the top cover is equipped with an observation window, which allows staff to observe the operating status of the internal components of the base station without opening the top cover, thus improving maintenance convenience.

[0015] Preferably, the housing is equipped with a handle, which facilitates the handling and movement of the base station and improves the portability of the device.

[0016] Preferably, a connecting plate for fixing is installed at the end of the housing away from the top cover. The connecting plate can be provided with mounting holes to facilitate fixing the base station in a designated position and improve the stability of the installation.

[0017] With the above structure, this utility model has the following advantages:

[0018] This utility model relates to an intrinsically safe wireless base station for mining based on WiFi 7. Utilizing WiFi 7 communication technology, it boasts advantages such as high speed, low latency, and strong anti-interference capabilities, effectively improving communication quality in underground mines. By setting a sealing ring between the top cover and the housing, and employing a rectangular structure in conjunction with a support plate to position the sealing ring, the waterproof and dustproof sealing performance of the equipment is significantly improved, adapting to the harsh working environment of mines. The locking mechanism employs a combination of locking block one, locking block two, locking plate, limit rod, limit disc, and limit piece, supplemented by locking springs and adjusting springs, achieving reliable locking and convenient opening and closing of the top cover and housing, ensuring the stability of the sealing effect. The observation window facilitates observation of the equipment's internal operating status by personnel, the handle enhances the equipment's portability, and the connecting plate facilitates the fixed installation of the equipment. The overall structural design is reasonable and highly practical.

[0024] The present invention will now be described in further detail in conjunction with the full text.

[0025] Combined with appendix Figures 1-3A WiFi 7-based intrinsically safe wireless base station for mining includes a housing 1 made of high-strength alloy material, possessing excellent pressure and impact resistance, and adaptable to the complex environment of underground mines. A top cover 2 is connected to the housing 1 via hinges made of corrosion-resistant stainless steel, ensuring the flexibility and lifespan of the top cover 2. A sealing ring (existing technology, not shown in the drawings) is installed between the top cover 2 and the housing 1 for sealing. The sealing ring is made of oil-resistant and aging-resistant nitrile rubber, effectively preventing dust and moisture from entering the equipment.

[0026] Specifically, the external dimensions of this utility model are as follows: Figure 1 As shown: 337mm×336mm×149mm, weight: approximately 4kg, place in a well-ventilated, dry place that is easy to install.

[0027] When this utility model is implemented, such as Figure 2 and Figure 3 As shown, a locking mechanism 6 for opening and closing the upper cover 2 is installed on one side of the housing 1. The locking mechanism 6 includes a locking block 601 fixedly connected inside the housing 1 and a locking block 602 hinged to the outside of the upper cover 2. Both locking blocks 601 and 602 are made of high-strength engineering plastic, which is lightweight and strong. A locking plate 603 is slidably installed at the lower end of the locking block 602. A limiting rod 604 is movably installed on one side of the locking block 601. A limiting plate 605 is off-axis set at one end of the limiting rod 604. A limiting piece 606 is installed at the end of the limiting plate 605 near the limiting rod 604. The locking piece 603 has a through hole 607 for the limiting plate 605 to enter and a limiting hole 608 for the limiting piece 606 to be inserted. The through hole 607 has an inverted triangular structure to facilitate the quick insertion of the limiting plate 605.

[0028] Specifically, one side of the locking block 601 has a moving groove 10 that moves with the limiting rod 604. A locking spring 11 is installed between the side wall of the moving groove 10 and the limiting rod 604, which can apply a continuous pulling force to the limiting rod 604 to ensure a tight fit between the limiting piece 606 and the limiting hole 608. The lower end of the locking block 602 has a sliding groove 12 that slides with the locking piece 603. An adjusting spring 13 is provided between the inner wall of the sliding groove 12 and the locking piece 603, which can drive the locking piece 603 to automatically reset when unlocking.

[0029] Specifically, the outer side of the top cover 2 folds inward to form a rectangular structure. A support plate 4 is installed on the inner side of the upper end of the housing 1. The support plate 4 and the housing 1 are integrally formed, improving structural stability. A sealing ring is installed between the rectangular structure and the support plate 4. The cooperation between the rectangular structure and the support plate 4 can reliably position the sealing ring, preventing displacement of the sealing ring and affecting the sealing effect. An observation window glass 9 is installed on the front of the top cover 2. The observation window glass is made of explosion-proof glass, which has good light transmission and explosion-proof performance, making it convenient for staff to observe the operating status of the internal components of the base station.

[0030] Specifically, a handle 8 is installed on the housing 1, and the handle 8 is fixed to the housing 1 with bolts, facilitating the handling and movement of the base station. A connecting plate 7 for fixing is installed at the end of the housing 1 away from the top cover 2. The connecting plate 7 has four mounting holes, and the base station can be fixed in a designated position with expansion bolts, improving the stability of the installation. Connecting sections 5 for connecting optical fibers are installed on both sides of the housing 1. The connecting sections 5 are waterproof optical fiber connectors to ensure the reliability and sealing of the optical fiber connection.

[0031] The working principle of this utility model:

[0032] During installation, the base station is fixed in a designated location in the mine shaft through the mounting holes on the connecting plate 7. The optical fiber is connected to the base station through the connecting joints 5 on both sides of the housing 1 to achieve communication connection. When the top cover 2 is closed, rotate the top cover 2 to fit it against the housing 1, then rotate the second locking block 602 to correspond with the first locking block 601, push the locking piece 603, and make the locking piece 603 slide along the sliding groove 12. The adjusting spring 13 is stretched, and the limiting rod 604 and the limiting plate 605 pass through the through hole 607 on the locking piece 603. The locking spring 11 is stretched, so that the limiting piece 606 is inserted into the limiting hole 608. Under the reverse force of the locking spring 11, the limiting rod 604 is subjected to continuous tension, ensuring that the limiting piece 606 and the limiting hole 608 are tightly fitted, realizing the locking of the locking mechanism 6. The limiting plate 605 is located at the lower end of the inverted triangular structure of the through hole 607, realizing secondary limiting. At this time, the sealing ring achieves a good sealing effect under the compression of the rectangular structure and the support plate 4.

[0033] When the top cover 2 needs to be opened for maintenance, pull the limiting plate 605 to move the limiting rod 604. The locking spring 11 continues to stretch, causing the limiting piece 606 to disengage from the limiting hole 608. Then pull the locking piece 603 to allow the limiting rod 604 and the limiting plate 605 to pass through the through hole 607. The limiting plate 605 then disengages from the through hole 607. Rotate the second locking block 602 to open the top cover 2 for maintenance. Workers can observe the operating status of the internal components of the base station through the observation window 9 on the front of the top cover 2 without opening it, improving maintenance convenience.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
