Description

Technical Field

[0001] This utility model relates to the field of aviation electromagnetic devices, specifically to an auxiliary device for aviation electromagnetic devices. Background Technology

[0002] In airborne electromagnetic exploration, the detection system consists of onboard equipment such as airborne data acquisition and recording computers, and external transmitting and receiving coils mounted in the cabin. The transmitting device transmits a time-varying electromagnetic field (primary field) into the ground by controlling the current in the transmitting coil. The primary field induces a current in conductive objects underground, which in turn generates an induced electromagnetic field (secondary field). The secondary induced electromagnetic field decays over time, and the receiving coil can receive the induced voltage components in various directions of the secondary field. The secondary field is related to the electromagnetic properties of the underground material. By analyzing the induced voltage of the received secondary field, parameters such as the dielectric constant, conductivity, and magnetic permeability of the underground medium can be inferred. By detecting the target area, the electrical parameters of the area can be obtained, thereby inferring information such as the spatial distribution and shape of the underground material.

[0003] According to Chinese Patent No. CN213210501U, an auxiliary device for an aviation electromagnetic device is disclosed. This utility model solves the problem in the prior art where the attitude of the aircraft affects the exploration results during aviation electromagnetic exploration, ensuring the relative position of the transmitting coil and the receiving coil, and ensuring the accuracy of the exploration.

[0004] Regarding the aforementioned disclosed patent content, by setting up a connecting plate, a connecting rod, a transmitting coil mounting plate, a limiting rod, and a receiving coil plate, with the receiving coil plate threadedly connected to the limiting rod, the distance between the receiving coil plate and the transmitting coil plate can be adjusted, and the receiving coil plate can also be disassembled. However, the transmitting coil plate is mounted on the connecting plate via the connecting rod, and the connecting plate is located inside the mounting base. When the transmitting coil plate is damaged, it is difficult for workers to remove it from the connecting plate for replacement, thereby reducing the efficiency of disassembling and replacing the transmitting coil plate. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an auxiliary device for an aviation electromagnetic device to solve the technical problem of the inconvenience of disassembling and replacing the transmitting coil.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for an aviation electromagnetic device, including a mounting base, the mounting base having a cavity inside, a connecting plate inside the cavity, a connecting cylinder installed at the bottom of the connecting plate, and a connecting rod at the bottom of the connecting plate. A disassembly assembly is provided between the connecting rod and the connecting plate, and the disassembly assembly includes a cavity inside the connecting rod and slots on both sides inside the connecting cylinder. Two movable plates are provided inside the cavity, and multiple springs are installed between the two movable plates. A pressure rod extending through to the outside of the connecting rod is installed on the lower side of one side of the two movable plates. Friction pads are provided at the upper and lower sides of the cavity. A locking block extending into the slot is installed on the upper side of one side of each of the two movable plates.

[0007] By adopting the above technical solution, when it is necessary to remove the connecting rod and the transmitting coil mounting plate, the staff can first press the pressure rods on both sides of the connecting rod. The pressure rods move, causing the movable plate to move and squeezing the spring.

[0008] Furthermore, the assembly and disassembly assembly also includes a positioning groove located at the center of the bottom of the connecting plate, a positioning block is inserted inside the positioning groove, and the bottom of the positioning block is fixedly connected to the top of the connecting rod.

[0009] By adopting the above technical solution, the connecting rod can be positioned after the positioning block is inserted into the positioning groove, and the locking block is aligned with the locking groove at this time.

[0010] Furthermore, a transmitting coil mounting plate is installed at the bottom end of the connecting rod, and a bottom rod is provided at the bottom of the transmitting coil mounting plate, with a limiting ring sleeved on the outer wall of the bottom rod.

[0011] By adopting the above technical solution, the movement of the limit ring will drive the movement of the receiving coil mounting bracket, thereby adjusting the position of the receiving coil mounting bracket.

[0012] Furthermore, a receiving coil mounting bracket is installed on the outer wall of the limiting ring, and both the inner wall of the limiting ring and the outer wall of the bottom rod are threaded, with the limiting ring and the bottom rod being threadedly connected.

[0013] By adopting the above technical solution, when the limiting ring is rotated, the limiting ring can move on the bottom rod to adjust the position of the limiting ring.

[0014] Furthermore, the outer wall of the connecting disc is provided with a groove, and a ball bearing is provided inside the groove, with the ball bearing in contact with the inner wall of the cavity.

[0015] By adopting the above technical solution, the ball bearings enable relative sliding of the connecting disc inside the cavity, ensuring that the relative angle between the transmitting coil and the ground remains fixed when the aircraft pitches, rolls, yaws, or rotates.

[0016] Furthermore, the mounting base has through holes at both the top and bottom, and the connecting rod is detachably connected to the connecting cylinder.

[0017] By adopting the above technical solution, it is convenient to disassemble and assemble the connecting rod.

[0018] Furthermore, the top and bottom of the movable plate are both in contact with the friction pad, and the movable plate is slidably connected to the cavity.

[0019] By adopting the above technical solution, the movable plate can slide inside the cavity, and the movement of the movable plate will drive the movement of the locking block.

[0020] Furthermore, the length of the pressure rod is greater than the length of the locking block, and the locking block is adapted to the locking slot.

[0021] By adopting the above technical solution, once the card block is inserted into the card slot, the connecting rod can be installed inside the connecting cylinder to prevent the connecting rod from falling off.

[0022] Furthermore, the mounting base, transmitting coil mounting plate, and receiving coil mounting bracket are all made of insulating material.

[0023] By adopting the above technical solutions and using insulating materials, the possibility of electromagnetic interference can be reduced, and the accuracy of exploration results can be improved.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by providing a disassembly and assembly component, allows for the removal of the connecting rod and the transmitting coil mounting plate. Workers can first press the pressure rods on both sides of the connecting rod. The pressure rods move, causing the movable plate to move and compress the spring. This compresses the spring, and the movable plate moves the locking block, allowing it to move out of the slot. Thus, the connecting rod and the transmitting coil mounting plate can be removed for replacement. To install the connecting rod and the transmitting coil mounting plate, repeat the above steps, pressing the pressure rods to move the locking block into the cavity. Then, insert the top of the connecting rod into the connecting cylinder, aligning the locking block with the slot. Next, with the spring tensioning, pull the pressure rods again, causing the movable plate to reset and move, moving the locking block until it engages with the slot, thus completing the installation of the connecting rod. This method allows for quick disassembly and assembly of the connecting rod and the transmitting coil mounting plate, with a simple and convenient process, improving efficiency.

[0026] 2. This utility model is provided with a positioning block and a positioning groove. When installing the connecting rod, the positioning block at the top of the connecting rod can be inserted into the positioning groove to position the connecting rod, so that the locking block and the locking groove can be aligned, making it easier for the locking block to be inserted into the locking groove for locking and limiting.

[0027] 3. This utility model increases the friction between the movable plate and the cavity by setting a friction pad, preventing the movable plate from sliding randomly, so that the movable plate can only be moved by pressing the pressure rod. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] An auxiliary device for an aircraft electromagnetic device, such as Figures 1-6As shown, the device includes a mounting base 1, with a cavity 2 inside the mounting base 1. A connecting plate 3 is installed inside the cavity 2, and a connecting cylinder 13 is installed at the bottom of the connecting plate 3. A connecting rod 6 is installed at the bottom of the connecting plate 3, and a disassembly assembly 9 is provided between the connecting rod 6 and the connecting plate 3. A transmitting coil mounting plate 7 is installed at the bottom of the connecting rod 6, and a bottom rod 8 is provided at the bottom of the transmitting coil mounting plate 7. A limiting ring 10 is sleeved on the outer wall of the bottom rod 8. When the limiting ring 10 moves, it will drive the receiving coil mounting frame 11 to move, thereby adjusting the position of the receiving coil mounting frame 11. The receiving coil mounting frame 11 is installed on the outer wall of the limiting ring 10, and both the inner wall of the limiting ring 10 and the outer wall of the bottom rod 8 are threaded.

[0039] See Figures 1-5 The limiting ring 10 is threadedly connected to the base rod 8. When the limiting ring 10 is rotated, it can move on the base rod 8 to adjust its position. The outer wall of the connecting plate 3 is provided with a groove 4, and a ball bearing 5 is provided inside the groove 4. The ball bearing 5 contacts the inner wall of the cavity 2. The ball bearing 5 enables the connecting plate 3 to slide relative to the cavity 2, ensuring that the relative angle between the transmitting coil and the ground is fixed when the aircraft pitches, rolls, or yaws. The top and bottom of the mounting base 1 are provided with through holes 12. The connecting rod 6 is detachably connected to the connecting cylinder 13, which facilitates the disassembly and assembly of the connecting rod 6. The mounting base 1, the transmitting coil mounting plate 7, and the receiving coil mounting bracket 11 are all made of insulating material. The use of insulating material reduces the possibility of electromagnetic interference and improves the accuracy of exploration results.

[0040] Specifically, the disassembly and assembly component 9 includes a cavity 903 inside the connecting rod 6 and slots 907 on both sides inside the connecting cylinder 13. The cavity 903 contains two movable plates 904, with multiple springs 906 installed between them. A pressure rod 905 extending through to the outside of the connecting rod 6 is installed on the lower side of one side of each of the two movable plates 904. Friction pads 909 are located at the upper and lower sides of the cavity 903. A locking block 908 extending into the slot 907 is installed on the upper side of one side of each of the two movable plates 904. When it is necessary to remove the connecting rod 6 and the transmitting coil mounting plate 7, the operator can first press the pressure rods 905 on both sides of the connecting rod 6. 05. The movement of the pressure rod 905 drives the movement of the movable plate 904 and compresses the spring 906. The top and bottom of the movable plate 904 are in contact with the friction pad 909. The movable plate 904 is slidably connected to the cavity 903. The movable plate 904 can slide inside the cavity 903. When the movable plate 904 moves, it will drive the locking block 908 to move. The length of the pressure rod 905 is greater than the length of the locking block 908. The locking block 908 is adapted to the locking groove 907. When the locking block 908 is inserted into the locking groove 907, the connecting rod 6 can be installed inside the connecting cylinder 13 to prevent the connecting rod 6 from falling off. The connecting plate 3, the connecting cylinder 13, the connecting rod 6, the bottom rod 8, and the pressure rod 905 are all made of insulating material.

[0041] Example 2:

[0042] Based on the above embodiment 1, in order to ensure that the card block 908 and the card slot 907 can be accurately aligned, the connecting rod 6 needs to be positioned, so the following structure will be set.

[0043] See Figure 2 , Figure 4 , Figure 5 and Figure 6 The assembly and disassembly assembly 9 also includes a positioning groove 901 located at the middle of the bottom of the connecting plate 3. A positioning block 902 is inserted inside the positioning groove 901. The positioning block 902 is adapted to the positioning groove 901, and the bottom of the positioning block 902 is fixedly connected to the top of the connecting rod 6. When the positioning block 902 is inserted into the positioning groove 901, the connecting rod 6 can be positioned, and at this time the locking block 908 is aligned with the locking groove 907.

[0044] The working principle of this utility model is as follows: First, the auxiliary equipment for the aviation electromagnetic device is used to connect the aircraft and the electromagnetic device. Through the cooperation between the ball bearing 5 and the inner wall of the cavity of the mounting base 1, the connecting plate 3 can slide relative to the cavity 2, ensuring that the relative angle between the transmitting coil and the ground is fixed when the aircraft pitches, rolls, yaws, or rotates. When it is necessary to adjust the distance between the receiving coil mounting bracket 11 and the transmitting coil mounting plate 7, the limiting ring 10 can be rotated to move the limiting ring 10, thereby driving the receiving coil mounting bracket 11 to move, so that the distance between the receiving coil mounting bracket 11 and the transmitting coil mounting plate 7 can be adjusted.

[0045] When it is necessary to remove the connecting rod 6 and the transmitting coil mounting plate 7, the operator can first press the pressure rods 905 on both sides of the connecting rod 6. The pressure rods 905 move, causing the movable plate 904 to move and compress the spring 906. This compresses the spring 906, and the movable plate 904 will move the locking block 908, causing the locking block 908 to move out of the slot 907. In this way, the connecting rod 6 and the transmitting coil mounting plate 7 can be removed for replacement. When installing the connecting rod 6 and the transmitting coil mounting plate 7, repeat the above steps by pressing the pressure rods 905 to make the locking block 908 move out of the slot 907. Block 908 is moved into the cavity 903, and then the top of the connecting rod 6 is inserted into the connecting cylinder 13, and the positioning block 902 is inserted into the positioning groove 901 so that the locking block 908 is aligned with the groove 907. Then, with the spring 906 stretching and pulling the pressure rod 905, the movable plate 904 is reset and moved, which drives the locking block 908 to move, so that the locking block 908 is locked into the groove 907, thereby completing the installation of the connecting rod 6. In this way, the connecting rod 6 and the transmitting coil mounting plate 7 can be quickly disassembled and assembled.
