Description

Technical Field

[0001] The invention relates to the technical field of through-the-earth antennas, and in particular to a ring-shaped matrix antenna used for through-the-earth communication of wireless electronic detonators. Background Art

[0002] In mining and other situations where wireless communication through the ground is required, for example, when wireless electronic detonators are used for blasting, antennas are needed for communication to achieve the detonation of wireless electronic detonators.

[0003] Common antenna equipment currently on the market is large in size, inconvenient to carry and install, especially in complex and changeable field working environments, which greatly limits its scope of application.

[0004] Secondly, the structure of existing antennas limits their signal transmission capabilities, especially because the rocks, soils, and minerals in the strata have significant absorption and scattering effects on radio waves, causing the signal to decay rapidly during transmission. This attenuation phenomenon significantly reduces the communication distance and signal strength of traditional antennas in underground or deeply buried environments, seriously affecting the reliability and stability of communications. In addition, metal deposits and other conductive materials in the strata will further aggravate the shielding effect of the signal, making it difficult for radio waves to penetrate or even completely blocked.

[0005] Based on this, there is an urgent need for a ring matrix antenna for wireless electronic detonators through-the-ground communication, which can solve the problems of poor portability and poor penetration of traditional antennas and greatly improve the portability and penetration of the antenna. Summary of the invention

[0006] One of the purposes of the present invention is to provide a ring matrix antenna for wireless electronic detonator through-the-ground communication, which can solve the problems of poor portability and poor penetration of traditional antennas and greatly improve the portability and penetration of the antenna.

[0007] In order to achieve the above object, a ring matrix antenna for wireless electronic detonator through-the-ground communication is provided, comprising a plurality of antenna bodies and connecting rods, wherein the interior of the antenna body is hollow;

[0008] The antenna body includes an end point connector, and a plurality of mutually independent arc-shaped antenna units and a quick connector;

[0009] The arc-shaped antenna units are detachably connected via quick connectors or end connectors;

[0010] The antenna bodies are detachably connected in a vertical direction via a quick connector and a connecting rod.

[0011] Technical principle and effect of this scheme: In this scheme, the interior of the antenna body is hollow, and the turns of wires are set up through the hollow setting. First, the arc antenna units are detachably connected in pairs through quick connectors until only one end of two arc antenna units is not connected. At this time, the turns of wires are extended into the interior of one of the arc antenna units, and then into the other arc antenna units in turn, and extended from another arc antenna unit. Finally, the last two arc antenna units are detachably connected through the end point connectors, thereby realizing the construction of a single antenna body. After the construction of all antenna bodies is completed, the detachable connection in the vertical direction between different antenna bodies is realized through the cooperation between the quick connector and the connecting rod.

[0012] 1. The antenna body is composed of multiple independent arc-shaped antenna units, each of which is detachably connected through quick connectors or end connectors. This modular design makes the installation and maintenance of the antenna more convenient, and also improves the flexibility and reliability of the system. The interior of the antenna body is hollow, and the turns of wires are set through the hollow setting. This design reduces the impact of the external environment on the wires and improves the stability and quality of signal transmission.

[0013] 2. Through the cooperation of quick connectors and connecting rods, the antenna bodies can be detachably connected in the vertical direction, thus presenting a ring matrix structure as a whole. This structure can form a tight and efficient signal transmission and reception network, effectively enhancing the signal penetration ability. The ring antenna body usually operates in the low frequency band. The attenuation of low-frequency waves in the stratum is small, and the penetration ability is stronger, which can effectively overcome the attenuation and shielding effect of the stratum on radio waves. At the same time, it also expands the receiving range, so that the antenna can effectively receive and send signals in different directions. That is, it can solve the problems of poor portability and poor penetration of traditional antennas, greatly improving the portability and penetration of the antenna.

[0014] Furthermore, the quick connector includes an arc-shaped body, a first through hole is opened along the arc direction on the arc-shaped body for the arc-shaped antenna unit to extend into, connecting blocks are arranged on the front side wall and the rear side wall of the arc-shaped body, and a first connecting groove is opened on the connecting block for the connecting rod to extend into.

[0015] Beneficial effects: The design of the arc-shaped body and the connecting block allows each antenna unit to be produced and transported independently. During on-site assembly, it is only necessary to insert the arc-shaped antenna unit into the first through hole and the connecting rod into the first connecting groove. The first through hole on the arc-shaped body and the first connecting groove on the connecting block work together to form a multi-point fixed structure, ensuring the connection stability between the antenna unit and the connecting rod. The antenna body and the assembly between antenna bodies can be quickly completed.

[0016] Furthermore, it includes two antenna bases, which include a first transverse rod, the middle part of which is rotatably connected to a second transverse rod, the left and right ends of the first transverse rod are rotatably connected to a first support rod, and an antenna body limiting portion is provided on the same side of one end of the two first support rods away from the first transverse rod.

[0017] Beneficial effect: In this solution, by rotating the second transverse rod so that the second transverse rod is away from the first transverse rod, a plurality of ground support rods are formed at the bottom, that is, by adjusting the angles of the first support rod and the second transverse rod, the height and stability of the antenna can be ensured under different terrain conditions (such as flat ground, slope, uneven ground, etc.), so that it is always in the best working state. The first support rods at the left and right ends are rotated so that the first support rods are away from the first transverse rod until the first support rod is in a vertical setting, and then the antenna body is supported on the left and right through the antenna body limit parts on the left and right first support rods, thereby achieving the corresponding support of the entire device.

[0018] Furthermore, a vertical limiting plate is provided on the outer side wall of the first transverse rod close to the first supporting rod.

[0019] Beneficial effect: By setting the vertical limit plate, the maximum rotation angle of the first support rod can be ninety degrees, so that the first support rod can maintain a vertical state after completing the support.

[0020] Furthermore, the first transverse rod, the second transverse rod, the first support rod and the antenna body limiting portion are all made of high-strength and corrosion-resistant materials.

[0021] Beneficial effects: The selected materials have extremely high mechanical strength and can withstand large external impacts without deformation or breakage, thus ensuring the stability and reliability of the antenna structure, and can work normally even in extreme weather conditions. Due to the use of materials with excellent corrosion resistance, the antenna components can maintain good physical and chemical properties in corrosive environments such as salt spray and acid rain, extending the service life and reducing maintenance costs.

[0029] like Figure 2 As shown, the antenna body 1 includes an end point connector 6, and a plurality of mutually independent arc-shaped antenna units 4 and a quick connector 5;

[0030] The arc-shaped antenna units 4 are detachably connected via quick connectors 5 or end connectors 6;

[0031] The antenna bodies 1 are detachably connected in a vertical direction via a quick connector 5 and a connecting rod 3 .

[0032] The quick connector 5 includes an arc-shaped body, a first through hole for the arc-shaped antenna unit 4 to extend into is opened on the arc-shaped body along the arc direction, connecting blocks are arranged on the front side wall and the rear side wall of the arc-shaped body, and a first connecting groove for the connecting rod 3 to extend into is opened on the connecting block.

[0033] like Figure 3 As shown, two antenna bases 2 are also included, the antenna base 2 includes a first transverse rod 20, the middle of the first transverse rod 20 is rotatably connected to the second transverse rod 21, the left and right ends of the first transverse rod 20 are rotatably connected to the first support rod 22, and the antenna body limiting portion 23 is provided on the same side of the two first support rods 22 away from the first transverse rod 20. In this embodiment, the first transverse rod 20 and the second transverse rod 21, the first transverse rod 20 and the first support rod 22 are all rotatably connected through a rotation axis.

[0034] A vertical stop plate is provided on the outer side wall of the first transverse rod 20 near the first support rod 22. In this embodiment, the first transverse rod 20, the second transverse rod 21, the first support rod 22 and the antenna body stop portion 23 are all made of high-strength and corrosion-resistant materials.

[0035] When arriving at the antenna placement point, first move the second transverse rod 21 away from the first transverse rod 20 until the angle between the second transverse rod 21 and the first transverse rod 20 reaches a preset maximum angle, and then rotate the two first support rods 22 away from the first transverse rod 20 until the angle between the two first support rods 22 and the first transverse rod 20 is ninety degrees. Then assemble the antenna body 1, that is, the arc antenna units 4 are sequentially socketed through the first through holes in the quick connector 5 to form a corresponding annular structure corresponding to the corresponding antenna body 1. Finally, the last two arc antenna units 4 are detachably connected through the end connector 6, thereby realizing the construction of a single antenna body 1. After completing the construction of all antenna bodies 1, the detachable connection in the vertical direction between different antenna bodies 1 is realized through the cooperation between the quick connector 5 and the connecting rod 3.

[0036] After completing the installation of the entire antenna, the front and rear antenna bodies 1 forming the ring matrix structure are placed on the antenna body limiting parts 23 on the first support rods 22 of the two antenna bases 2.

If the first button is pressed, the first controller is used to start the first cylinder, so that the piston rod of the first cylinder extends outward, thereby realizing the outward extension of the first connecting rod 3, and then realizing the expansion of the distance between the antenna bodies 1. Similarly, after the second button is pressed, the distance between the antenna bodies 1 can be reduced. In this way, the distance between the antenna bodies 1 can be adjusted.
