Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment technology, and more specifically, to a remote control antenna device. Background Technology

[0002] In harsh working environments such as mining, effective antenna protection is crucial for ensuring the stability and security of wireless communication systems. Antennas in mines frequently face risks such as physical impacts, weather changes, and contact with corrosive substances. On automated coal mining machines, antenna protection is even more critical. Most traditional antenna installations simply expose the antenna itself or place a simple protective shell around it, offering limited protection against impacts from gravel and rocks in the mining environment. Some designs employ sealed protective shells to protect the antenna, but this often leads to signal attenuation and affects communication quality. Currently, installing shockproof and impact-resistant covers or using special materials to protect the antenna makes it difficult to achieve a balance between signal quality and protective strength, and also increases the complexity and cost of the device.

[0003] In other words, existing remote control antenna devices suffer from the problem of balancing antenna signal quality and protection strength. Utility Model Content

[0004] The main objective of this invention is to provide a remote control antenna device to solve the problem of balancing signal quality and protection strength in existing remote control antenna devices.

[0005] To achieve the above objectives, this utility model provides a remote control antenna device, comprising: an electrical control box having a housing; an antenna, at least a portion of which extends outside the housing; a connecting mechanism, at least a portion of which is fixed to the outside of the housing and sleeved on the antenna, and at least another portion of which is located inside the housing and connected to one end of the antenna, so that the antenna and the electrical control box are connected; and a containment mechanism fixed to the housing, having a containment space, wherein the portion of the antenna extending out of the housing is located within the containment space.

[0006] Furthermore, the connecting mechanism includes a fixing assembly disposed on the outside of the receiving housing. The fixing assembly includes: a fixing plate fixed to the outside of the receiving housing, the fixing plate having a clearance hole for the antenna to pass through the clearance hole; and a locking member sleeved on the antenna, at least a portion of the locking member extending into the clearance hole.

[0007] Furthermore, the fixing plate is sealed to the outside of the housing.

[0008] Furthermore, the connection mechanism includes an intrinsically safe component disposed inside the housing. The intrinsically safe component includes: a connection housing, one end of which communicates with the housing to allow one end of the antenna to extend into the connection housing; a connector, one end of which is connected to the antenna; a converter, one end of which is connected to the end of the connector away from the antenna; and a wire guide assembly, which is connected to the end of the converter away from the antenna.

[0009] Furthermore, the connecting housing has an intrinsically safe cavity, and the converter is located within the intrinsically safe cavity.

[0010] Furthermore, at least a portion of the wire guide assembly is located outside the connecting housing, and the intrinsically safe assembly also includes a locking nut fitted onto the wire guide assembly.

[0011] Furthermore, the housing includes a countersunk hole and a cover plate, with the cover plate disposed within the countersunk hole, and the antenna, connecting mechanism, and enclosure mechanism all located on the cover plate.

[0012] Furthermore, the outer circumferential surface of the cover plate is an explosion-proof mating surface.

[0013] Furthermore, the enclosure mechanism includes a protective sleeve that surrounds the outside of the antenna. The protective sleeve is made of metal and has multiple through holes with a diameter larger than the communication wavelength of the antenna.

[0014] Furthermore, the antenna has an enlarged diameter section near one end of the housing, at least a portion of which is located within the connecting mechanism.

[0015] According to the technical solution of this utility model, the remote control antenna device includes an electrical control box, an antenna, a connecting mechanism, and a enclosure mechanism. The electrical control box has a housing. At least a portion of the antenna extends out of the housing. At least a portion of the connecting mechanism is fixed to the outside of the housing and sleeved on the antenna. At least another portion of the connecting mechanism is located inside the housing and connected to one end of the antenna, so that the antenna and the electrical control box are connected. The enclosure mechanism is fixed to the housing and has an enclosure space. The portion of the antenna extending out of the housing is located within the enclosure space.

[0016] To balance signal transmission and effective protection of the remote control antenna device, the control box, as a major component, has a closed housing to protect the internal wiring from external environmental influences. The antenna extends beyond the housing to enhance its signal reception and transmission capabilities; this extended portion is a critical area for signal transmission, facilitating full exposure to capture external signals. One side of the connecting mechanism is fixed to the outside of the housing and fitted onto the antenna, ensuring a secure connection between the antenna and the external structure of the control box, while also providing protection. The other side of the connecting mechanism is located inside the housing and tightly connected to one end of the antenna, ensuring electrical connection between the antenna and the internal wiring of the control box, enabling effective signal conversion and transmission. A containment mechanism is fixed to the housing, surrounding the extended portion of the antenna to form a containment space, providing additional physical protection for the antenna and preventing direct impact and damage from the external environment. This invention, while ensuring antenna signal transmission performance, solves the problem of balancing signal strength and protection performance in harsh environments by using a secure connection mechanism and an effective containment mechanism.

[0026] To address the challenge of balancing signal quality and protection strength in existing remote-controlled antenna devices, this invention provides a remote-controlled antenna device.

[0027] like Figures 1 to 3 As shown, the remote control antenna device includes an electrical control box 10, an antenna 20, a connecting mechanism, and a enclosure mechanism. The electrical control box 10 has a housing 11. At least a portion of the antenna 20 extends out of the housing 11. At least a portion of the connecting mechanism is fixed to the outside of the housing 11 and sleeved on the antenna 20. At least another portion of the connecting mechanism is located inside the housing 11 and connected to one end of the antenna 20, so that the antenna 20 and the electrical control box 10 are connected. The enclosure mechanism is fixed to the housing 11 and has an enclosure space. The portion of the antenna 20 extending out of the housing 11 is located within the enclosure space.

[0028] To balance signal transmission and effective protection of the remote control antenna device, the control box 10, as a major component of the device, has a closed housing 11 to protect the internal wiring from external environmental influences. The antenna 20 extends beyond the housing 11 of the control box 10 to enhance its signal reception and transmission capabilities. This extended portion is a critical area for signal transmission, facilitating full exposure to capture external signals. One side of the connecting mechanism is fixed to the outside of the housing 11 and fitted onto the antenna 20, ensuring a secure connection between the antenna 20 and the external structure of the control box 10, while also providing protection. The other side of the connecting mechanism is located inside the housing 11 and tightly connected to one end of the antenna 20, ensuring electrical connection between the antenna 20 and the internal wiring of the control box 10, enabling effective signal conversion and transmission. A containment mechanism is fixed to the housing 11, surrounding the extended portion of the antenna 20 to form a containment space, providing additional physical protection for the extended portion of the antenna 20, preventing direct impact and damage from the external environment, and avoiding signal transmission loss caused by direct contact with the antenna 20. This application, while ensuring the signal transmission performance of antenna 20, solves the problem of balancing signal strength and protection performance of remote control antenna devices in harsh environments through the stable connection of the connecting mechanism and the effective protection of the enclosure mechanism.

[0029] like Figure 2 As shown, the connecting mechanism includes a fixing component 31, which is disposed on the outside of the housing 11. The fixing component 31 includes a fixing plate 32 and a locking member 33. The fixing plate 32 is fixed to the outside of the housing 11 and has a clearance hole 34 to allow the antenna 20 to pass through the clearance hole 34. The locking member 33 is sleeved on the antenna 20, and at least a portion of the locking member 33 extends into the clearance hole 34. The fixing plate 32 of the fixing component 31 is directly fixed to the outside of the housing 11, forming an integral part with the housing 11. This ensures that the protruding part of the antenna 20 can be fixed and protected, preventing the antenna 20 from moving when the remote control antenna device encounters vibration or impact, and ensuring the continuity and reliability of communication. The clearance hole 34 on the fixing plate 32 ensures that the antenna 20 can pass through smoothly without affecting the signal reception and transmission capabilities of the antenna 20. The locking member 33 is fitted around the outer periphery of the antenna 20, and a portion of the locking member 33 extends into the clearance hole 34 on the fixing plate 32, forming a stable connection with the fixing plate 32. This combination of fitting and extending allows the locking member 33 to firmly fix the antenna 20, preventing the antenna 20 from loosening during the movement of the remote control antenna device.

[0030] Alternatively, the locking element 33 can be a round tightening nut, which serves to wrap around and secure the antenna 20.

[0031] like Figure 2As shown, the fixing plate 32 is sealed to the outside of the housing 11. The fixing plate 32 is installed on the outside of the housing 11, stably connecting the antenna 20 to the housing 11. This sealed connection ensures the tightness of the contact surface between the fixing plate 32 and the housing 11, preventing moisture, dust, and other contaminants from entering the housing 11 and affecting the normal operation of the internal electrical equipment. Furthermore, this sealed connection not only ensures the stable installation of external components such as the antenna 20, but also makes the connection more robust, resisting external vibrations and impacts, thus improving the structural stability of the remote control antenna device in harsh environments.

[0032] like Figure 2 As shown, the connection mechanism includes an intrinsically safe component 35, which is disposed inside the housing 11. The intrinsically safe component 35 includes a connecting housing 36, a converter 37, a connector 38, and a wiring assembly 39. One end of the connecting housing 36 communicates with the housing 11, allowing one end of the antenna 20 to extend into the connecting housing 36. One end of the connector 38 is connected to the antenna 20. One end of the converter 37 is connected to the end of the connector 38 furthest from the antenna 20. The wiring assembly 39 is connected to the end of the converter 37 furthest from the antenna 20. The connecting housing 36 communicates with the housing 11 of the electrical control box 10, forming a closed space. One end of the antenna 20 can extend into the connecting housing 36, ensuring physical continuity and electrical isolation between the antenna 20 and the internal wiring of the electrical control box 10, while providing a protected environment for the antenna 20. The connector 38 and the converter 37 are sequentially connected in the direction furthest from the antenna 20, ensuring the safe operation of the converter 37 and avoiding interference from the external environment. Converter 37 converts the wireless signal received by antenna 20 into an electrical signal, and also converts the electrical signal generated by the internal wiring of the control box 10 into a wireless signal, facilitating signal transmission and processing. One end of connector 38 is directly connected to antenna 20, acting as a bridge between antenna 20 and the internal wiring of the control box 10. Connector 38 has good electrical performance and structural strength, ensuring stable signal transmission and antenna 20 fixation. Wiring guide 39 is connected to the end of converter 37 furthest from antenna 20, used to transmit electrical signals from converter 37 to other circuit components inside the control box 10, ensuring efficient signal transmission while meeting the explosion-proof and waterproof requirements of the remote control antenna device, guaranteeing its safety and stability. The connection between converter 37, connector 38, and wiring guide 39 enables efficient conversion and transmission of signals received or transmitted by antenna 20, improving the communication reliability of the remote control antenna device.

[0033] like Figure 2As shown, the connecting housing 36 has an intrinsically safe cavity 40, within which the converter 37 is located. Placing the converter 37 within the intrinsically safe cavity 40 effectively prevents electrical sparks or thermal effects generated by the internal circuitry under abnormal conditions from igniting surrounding explosive gases. This effectively avoids the converter 37 being affected by harsh external environments, extending its service life and ensuring the safe operation of the entire electronic control system. Furthermore, the intrinsically safe cavity 40 takes into account the signal transmission path and method to reduce signal attenuation and interference. The converter 37's location within the intrinsically safe cavity 40 optimizes the signal transmission path between it and the antenna 20, maximizing signal conversion efficiency and thus improving the reliability of the remote control antenna device.

[0034] It should be noted that the intrinsically safe cavity 40 in this application, i.e., the intrinsically safe cavity, is a sealed cavity that can limit the energy of possible electric sparks or thermal effects generated inside, so that it is insufficient to ignite an explosive gas mixture.

[0035] like Figure 2 As shown, at least a portion of the wire guide assembly 39 is located outside the connecting housing 36. The intrinsically safe component 35 also includes a locking nut 41, which is fitted onto the wire guide assembly 39. The wire guide assembly 39 is used to transmit electrical signals in the remote control antenna device, and at least a portion of it must be located outside the connecting housing 36 to enable signal connection between the antenna 20 and external devices. The external structure of the wire guide assembly 39 must possess certain protective and isolation properties to ensure the signal transmission quality and equipment safety of the remote control antenna device in harsh environments, prevent the wire guide assembly 39 from loosening due to external factors, avoid potential short circuits or sparks, and ensure the safety of equipment and personnel.

[0036] Optionally, at least a portion of the locking nut 41 extends into the connecting housing 36, is sleeved on the wire guide assembly 39 and is in close contact with the wire guide assembly 39. The explosion-proof thread of the locking nut 41 engages with the wire guide assembly 39 to fix the wire guide assembly 39 to the connecting housing 36, ensuring the stability and sealing of the wire guide assembly 39.

[0037] like Figure 1As shown, the housing 11 includes a countersunk hole 12 and a cover plate 13. The cover plate 13 is disposed within the countersunk hole 12, and the antenna 20, connecting mechanism, and enclosure mechanism are all located on the cover plate 13. The countersunk hole 12 is a space recessed from the outer wall of the housing 11 into the interior of the housing 11, used to install the cover plate 13. The cooperation between the cover plate 13 and the countersunk hole 12 allows the cover plate 13 to securely cover the countersunk hole 12 and become part of the housing 11. The antenna 20, connecting mechanism, and enclosure mechanism are integrated together on the cover plate 13. At least a portion of the antenna 20 extends out of the cover plate 13, ensuring signal reception and transmission performance. The connecting mechanism is fixed to the cover plate 13, connecting the antenna 20 to the internal wiring of the electrical control box 10. The enclosure mechanism surrounds the extended portion of the antenna 20, forming an enclosure space to provide physical protection, ensuring signal transmission efficiency and achieving a balance between protection and signal performance. Furthermore, the antenna 20, connecting mechanism, and enclosure mechanism are concentrated on the cover plate 13, making installation and maintenance more convenient. When maintenance is required on the antenna 20 or the connecting mechanism, only the cover plate 13 needs to be removed without entering the interior of the electrical control box 10, simplifying the operation of the remote control antenna device.

[0038] like Figures 1 to 3 As shown, the enclosure mechanism includes a protective sleeve 43, which surrounds the outside of the antenna 20. The protective sleeve 43 is made of metal and has multiple through holes, the diameter of which is larger than the communication wavelength of the antenna 20. The protective sleeve 43 surrounds the outside of the antenna 20, meaning it is directly fitted around the antenna 20 without contacting it or hindering its normal extension, retraction, or rotation. This ensures that it forms a protective layer around the antenna 20 without affecting its communication function. The protective sleeve 43 has multiple through holes with specified diameters, ensuring that wireless signals can freely enter and exit the sleeve, avoiding signal attenuation or shielding. The shape and size of the through holes also ensure the structural strength and protective effect of the protective sleeve 43. In addition, the metal protective sleeve 43 provides strong structural strength and wear resistance, which can effectively protect the antenna 20 from the impact of gravel, rock collisions and other external environmental factors, and prevent the antenna 20 from malfunctions such as deformation, breakage or damage to signal receiving components, thereby improving the service life of the antenna 20 and the operational stability of the remote control antenna device.

[0039] Optionally, the protective sleeve 43 is welded to the outside of the housing 11 of the electrical control box 10, which greatly improves the protective sleeve 43's ability to cope with harsh environments and ensures signal transmission.

[0040] like Figures 1 to 3As shown, the antenna 20 has an expanded diameter section 21 at one end near the housing 11, and at least a portion of the expanded diameter section 21 is located within the connecting mechanism. The expanded diameter section 21 at the end of the antenna 20 near the housing 11 gradually widens in diameter towards the interior of the housing 11, enhancing the connection stability between the antenna 20 and the connecting mechanism. At the junction of the antenna 20 and the housing 11 of the electrical control box 10, i.e., within the fixing assembly 31 of the connecting mechanism, the expanded diameter section 21 has connecting housings 36, fixing plates 32, or locking elements 33 distributed around its outer periphery to achieve a stable connection between the antenna 20 and the electrical control box 10, preventing loosening or damage to the antenna 20 due to vibration or impact, and improving the reliability of the antenna 20.

[0041] Specifically, the enlarged diameter section 21 has a threaded hole at one end near the connector 38 for screwing the connector 38 in place. An insulating washer is provided between the end face of the enlarged diameter section 21 near the connector 38 and the connector 38.

[0042] Example 1

[0043] like Figures 1 to 3 As shown, a remote control antenna device according to Embodiment 1 of this application is described.

[0044] like Figure 1 As shown, the outer peripheral surface of the cover plate 13 is used as the explosion-proof mating surface for the housing 11. The explosion-proof mating surface is located on the outer peripheral surface of the cover plate 13, that is, the edge part of the cover plate 13 that contacts the housing of the electrical control box 10 is designed with explosion-proof features to ensure that in the event of an explosion of the remote control antenna device, flames and explosion pressure are prevented from propagating to the external environment through the contact surface, thereby preventing the spread of the explosion.

[0045] Specifically, the cover plate 13 has a sealing groove 14 on the side near the housing 11, and an O-ring is installed in the sealing groove 14 to meet the requirements of waterproofing and moisture protection.

[0046] It should be noted that the design of the explosion-proof joint surface follows explosion-proof standards, such as the provisions of GB3836-2021.

[0047] Specifically, the protective sleeve 43 is made of high-strength wear-resistant steel, which can effectively avoid affecting the transmission and reception of signals by the antenna 20, while also effectively preventing larger gravel particles from passing through.

[0048] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0049] 1. To balance signal transmission and effective protection of the remote control antenna device, the control box 10, as the main component of the remote control antenna device, has a closed housing 11 to protect the internal wiring from the influence of the external environment. The antenna 20 extends out of the housing 11 of the control box 10 to enhance the signal reception and transmission capabilities of the antenna 20. The extended part of the antenna 20 is a key area for signal transmission, which is beneficial for full exposure to capture external signals.

[0050] 2. One side of the connecting mechanism is fixed to the outside of the housing 11 of the electrical control box 10 and sleeved on the antenna 20, ensuring a stable connection between the antenna 20 and the external structure of the electrical control box 10, while also providing protection. The other side of the connecting mechanism is located inside the housing 11 and is tightly connected to one end of the antenna 20, ensuring the electrical connection between the antenna 20 and the internal wiring of the electrical control box 10, achieving effective signal conversion and transmission. The enclosure mechanism is fixed to the housing 11, surrounding the portion of the antenna 20 that extends out of the housing, forming an enclosure space, providing additional physical protection for the extended portion of the antenna 20, preventing the antenna 20 from being directly impacted and damaged by the external environment, and also avoiding signal transmission loss caused by direct attachment to the antenna 20.

[0051] 3. While ensuring the signal transmission performance of antenna 20, this application solves the problem that the signal strength and protection performance of remote control antenna devices in harsh environments are difficult to balance in the prior art through the stable connection of the connecting mechanism and the effective protection of the enclosure mechanism.
