Description

Technical Field

[0001] This invention relates to a detector, and more specifically, to a detector device with a universal structure. Background Technology

[0002] Referring to the utility model patent with authorization announcement number CN207423213U entitled "A Lossless Detector" and the utility model patent with authorization announcement number CN213275984U, since the moving coil detector works by relying on elastic elements to support the coil frame, the detector's optimal working state is when the detector axis is parallel to the vertical line. When the detector axis gradually deviates from the vertical line by more than 12°, the detector will not work properly or the output signal specifications will not match the actual situation. Therefore, when fixing the detector for practical applications, it is necessary to ensure that the detector is in a vertical state as much as possible.

[0003] When used on land, the usual practice is to set a horizontal bubble on the housing to observe or adjust the vertical working state of the detector. However, when the detector is used underwater or in other scenarios where the angle cannot be manually adjusted after assembly, the optimal working state of the detector cannot be guaranteed. Summary of the Invention

[0004] The present invention aims to solve the technical problem that existing detector products cannot solve the problem of working in the best working state on their own, and provides a detector device with a universal structure that can adjust the attitude of the detector combination to the best working state when multiple detectors are combined.

[0005] This invention provides a detector device with a universal structure, including a combined mounting base, an attitude adjustment frame, an adjustment frame, a detector core, and a circuit board;

[0006] The upper surface of the combined mounting base is provided with a mechanism hole, in which the detector mechanism is connected. The combined mounting base has two oppositely arranged bearing mounting holes in the radial direction, which are located on the upper side of the combined mounting base. Ball bearings are connected to the two bearing mounting holes respectively. The upper surface of the combined mounting base is provided with two cylindrical recesses, one cylindrical recess corresponding to one bearing mounting hole, and the cylindrical recesses are close to the bearing mounting holes.

[0007] The attitude adjustment frame is annular in shape. It has two oppositely arranged threaded holes and two oppositely arranged bearing fixing holes in the radial direction. The center lines of the two bearing fixing holes are perpendicular to the axes of the threaded holes. A total of four holes—the threaded holes and the bearing fixing holes—are evenly distributed in a square pattern along the circumference. An annular groove is provided on the inner cylindrical surface of the attitude adjustment frame. Two second rotating pairs are connected to the threaded holes. One end of each second rotating pair has an external thread, and the other end has a stepped cylindrical surface. A contact shaft connection hole is located in the middle of the second rotating pair. A circular through hole is located on the side of the second rotating pair at the stepped position. The external thread connects to the threaded hole of the attitude adjustment frame, and the stepped cylindrical surface connects to the ball bearing in the bearing fixing hole of the combined fixing seat. An insulating sleeve is provided inside the contact shaft connection hole, and the insulating sleeve connects to a contact shaft. One end of the contact shaft is rod-shaped, and the other end is hemispherical.

[0008] The adjustment frame is annular in shape and has two oppositely arranged threaded holes in the radial direction. Each of the two threaded holes on the adjustment frame is connected to a first rotating pair, for a total of two first rotating pairs. One end of the first rotating pair has an external thread, and the other end has a stepped cylindrical surface. A through hole is provided in the middle of the first rotating pair. The external thread of the first rotating pair is connected to the internal threaded hole of the adjustment frame, and the stepped cylindrical surface of the first rotating pair is connected to the bearing fixing hole of the attitude adjustment frame through a ball bearing.

[0010] The circuit board is fixedly connected to the upper surface of the mounting base. Several lead holes are provided on the circuit board corresponding to the positions of the detector core on the mounting base. Next to each lead hole on the circuit board is a positive electrode core pad and a negative electrode core pad. A first pad and a second pad are respectively located on both sides of the circuit board. The first pad is connected to the positive electrode core pad at one of the lead holes via a lead wire with attached solder mask. The second pad is connected to the negative electrode core pad at the other lead hole via a lead wire with attached solder mask. A first spring and a second spring are respectively connected to the first and second pads. The first spring is bent and placed into a cylindrical recess in the mounting base. After the second spring is bent, it is placed into another cylindrical recess in the combined fixing seat; the hemispherical end of the contact shaft in one of the second rotating joints contacts the first spring, and the hemispherical end of the contact shaft in the other second rotating joint contacts the second spring; two signal lines are provided in the annular groove.

The upper surface of the combined mounting base is provided with two cylindrical recesses, one cylindrical recess corresponding to one bearing mounting hole, and the cylindrical recesses are close to the bearing mounting holes.

[0017] The attitude adjustment frame is annular in shape. It has two oppositely arranged threaded holes and two oppositely arranged bearing fixing holes in the radial direction. The center lines of the two bearing fixing holes are perpendicular to the axes of the threaded holes. A total of four holes—the threaded holes and the bearing fixing holes—are evenly distributed in a square pattern along the circumference.

A circular through hole is located on the side of the second rotating pair at the stepped position. The external thread connects to the threaded hole of the attitude adjustment frame, and the stepped cylindrical surface connects to the ball bearing in the bearing fixing hole of the combined fixing seat. An insulating sleeve is provided inside the contact shaft connection hole, and the insulating sleeve connects to a contact shaft. One end of the contact shaft is rod-shaped, and the other end is hemispherical.

[0018] The bottom shell has two oppositely arranged threaded holes in the radial direction. Two first rotating pairs are connected to each of these threaded holes.

The stepped cylindrical surface of the first rotating pair connects to the bearing fixing hole of the attitude adjustment frame via a ball bearing.

[0019] The inner side of the attitude adjustment frame is connected to a third spring and a fourth spring. The third spring corresponds to one of the bearing fixing holes of the attitude adjustment frame and contacts the hemispherical end of the contact shaft of one of the first rotary pairs. The fourth spring corresponds to another bearing fixing hole of the attitude adjustment frame and contacts the hemispherical end of the contact shaft of the second first rotary pair.

[0020] The circuit board is fixedly connected to the upper surface of the mounting base. Several lead holes are provided on the circuit board corresponding to the positions of the detector core on the mounting base. Next to each lead hole on the circuit board is a positive electrode core pad and a negative electrode core pad. A first pad and a second pad are respectively located on both sides of the circuit board. The first pad is connected to the positive electrode core pad at one of the lead holes via a lead wire with attached solder mask. The second pad is connected to the negative electrode core pad at the other lead hole via a lead wire with attached solder mask. A first spring and a second spring are respectively connected to the first and second pads. The first spring is bent and placed into a cylindrical recess in the mounting base.

[0021] Each of the first rotary joints has a contact shaft connected to a lead wire, with a total of two leads extending from the top cover.

[0022] Preferably, in the order of lead holes A, B, C, G, D, E, F, the positive electrode core pad at A is connected to the first spring through a lead with an attached solder resist layer; the positive electrode core pad at B is connected to the negative electrode core pad at A through a lead with an attached solder resist layer; the positive electrode core pad at C is connected to the negative electrode core pad at B through a lead with an attached solder resist layer; the positive electrode core pad at G is connected to the negative electrode core pad at C through a lead with an attached solder resist layer; the positive electrode core pad at D is connected to the negative electrode core pad at G through a lead with an attached solder resist layer; the positive electrode core pad at E is connected to the negative electrode core pad at D through a lead with an attached solder resist layer; the positive electrode core pad at F is connected to the negative electrode core pad at E through a lead with an attached solder resist layer; and the negative electrode core pad at F is connected to the second spring through a lead with an attached solder resist layer.

[0023] A solder mask lead with a semi-circular solder joint is used to connect the negative electrode core pad of lead hole A to the positive electrode core pad of lead hole C. A solder mask lead with a semi-circular solder joint is used to connect the negative electrode core pad of lead hole A to the negative electrode core pad of lead hole C. A solder mask lead with a semi-circular solder joint is used to connect the negative electrode core pad of lead hole G to the positive electrode core pad of lead hole G. A solder mask lead with a semi-circular solder joint is used to connect the negative electrode core pad of lead hole D to the positive electrode core pad of lead hole F. A solder mask lead with a semi-circular solder joint H is used to connect the negative electrode core pad of lead hole D to the negative electrode core pad of lead hole F.

[0024] The circuit board has a first pad and a second pad on each side. The first pad is connected to the positive core pad of the lead hole A through a lead wire with an attached solder resist layer. The second pad is connected to the negative core pad of the lead hole F through a lead wire with an attached solder resist layer. The first pad and the second pad are respectively connected to a first spring and a second spring. The first spring is bent and placed into a cylindrical recess in the combined fixing base. The second spring is bent and placed into another cylindrical recess in the combined fixing base.

[0025] The beneficial effects of this invention are:

[0026] An attitude adjustment frame and an adjustment frame are respectively set on the outer layer of the combined fixed base. With the cooperation of a rotary joint and roller bearing, no matter how the adjustment frame is tilted or rotated, the combined fixed base can always be kept in a horizontal state, and the core fixed on it will always be kept in a vertical state, in the best working state.

[0027] Two sets of springs welded on both sides of the circuit board are connected at one end to the core assembly through the circuit board, and at the other end to the contact shaft of the rotary joint and conduction. At the same time, the rotary joint and the annular groove on the attitude adjustment frame can connect the electrical circuit of the core and extend it to the rotary joint on the adjustment frame, and further extend it to the outside of the adjustment frame. With this connection method, no matter how the assembly fixing seat is adjusted, the detector connection circuit can be fixedly connected to the outside of the adjustment frame.

[0028] In addition to the core pads, five semi-circular solder joints are also set in the empty space on the circuit board. By soldering different semi-circular solder joints with solder wire, the circuit can be made conductive. This can make the core position at a specific hole fail, and can still meet the circuit conductivity after reducing the number of series cores. More importantly, it can also achieve the commonality of the circuit board when different core numbers are applied.

[0029] With seven cores per layer, if each core is sequentially soldered to its corresponding core pad, and the semicircular solder joints are not conductive, the entire layer of the mounting bracket can be connected end-to-end to form a single unit. When the number of cores in the entire layer is even, no core is placed at core hole M. In this case, the semicircular solder joint M is conductive, while the other semicircular solder joints are not conductive. The six cores on the outer circumference are then connected end-to-end to form a single unit. When there are five cores in the assembly, the cores are placed at holes A, C, D, F, and G. The semicircular solder joints J and K are conductive, while the other semicircular solder joints are not conductive. When there are four cores in the assembly, the cores are placed at holes A, C, D, and F. The semicircular solder joints M, J, and K are conductive, while the other semicircular solder joints are not conductive. When three cores are assembled, the cores are placed in holes A, F, and G. The semicircular solder joints L and H are soldered to ensure conductivity, while the other semicircular solder joints are not conductive. When two cores are assembled, the cores are placed in holes A and F. The semicircular solder joints L, H, and M are soldered to ensure conductivity, while the other semicircular solder joints are not conductive. When only one core is used, it is placed in hole G, and the positive and negative terminals of the core are connected to the positive and negative pads of holes A and F, respectively.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] like Figure 1 , Figure 2 As shown, the detector device with a universal structure mainly includes an attitude adjustment frame 1, a combined fixing base 2, a detector core 5, a circuit board 6, and an adjustment frame 7.

[0046] like Figure 3 The combined mounting base 2 shown can be made of metal or non-metal materials. Several mechanism holes 2-1 are provided on the upper surface of the combined mounting base 2, mainly used as a fixing carrier for the detector core assembly. The detector core assembly can be a single longitudinal wave core or transverse wave core, or multiple longitudinal wave cores connected in series and parallel, or a three-component core with independent components distributed in a Cartesian coordinate system. The detector core 5 is installed in the mechanism holes 2-1, and the core assembly can be firmly fixed to the combined mounting base using a clamping structure or a compression structure. The combined mounting base 2 has two bearing mounting holes 2-2 in the radial direction, arranged opposite each other, located on the upper side of the combined mounting base 2. A ball bearing 9 is installed at each bearing mounting hole 2-2. The upper surface of the combined fixing seat 2 is provided with two cylindrical recesses 2-3, one cylindrical recess 2-3 corresponds to one bearing fixing hole 2-2, the cylindrical recess 2-3 is connected to the bearing fixing hole 2-2, and the cylindrical recess 2-3 is close to the bearing fixing hole 2-2.

[0047] like Figure 4 As shown, the attitude adjustment frame 1 is annular in shape, with two threaded holes 1-1 distributed radially (the two threaded holes 1-1 are arranged opposite each other), and two bearing fixing holes 1-2. The center lines of the two bearing fixing holes 1-2 are perpendicular to the axis of the threaded holes 1-1. A total of four holes—the two threaded holes 1-1 and the two bearing fixing holes 1-2—are evenly distributed in a square pattern along the circumference. An annular groove 1-3 is provided on the inner cylindrical surface of the attitude adjustment frame 1. A second rotating joint 11 is installed at each of the two threaded holes 1-1 (the external thread 11-1 of the second rotating joint 11 connects and mates with the threaded hole 1-1). There are two second rotating joints 11 in total, and each second rotating joint 11 mates with a ball bearing 9. When the attitude adjustment frame 1 rotates along the axis of the second rotating joint 11, the combined fixing seat 2, together with the detector mechanism 5, can rotate around the axis of the second rotating joint 11, while still maintaining a relatively horizontal state. A ball bearing 9 is installed at each of the two bearing fixing holes 1-2. On the inner side of the attitude adjustment frame 1, the third spring 18 and the fourth spring 19 are fixed with adhesive at each bearing fixing hole 1-2. The third spring 18 corresponds to one of the bearing fixing holes 1-2, and the fourth spring 19 corresponds to the other bearing fixing hole 1-2.

[0048] The ball bearing 9 is installed in the bearing mounting hole 1-2. One bearing mounting hole 1-2 corresponds to one ball bearing 9, and two bearing mounting holes 1-2 correspond to two ball bearings 9.

[0049] The adjusting bracket 7 is also annular, with two threaded holes 7-1 distributed radially (e.g., Figure 1 , 2 As shown in Figure 12), a first rotary joint 4 is installed at each of the two threaded holes 7-1 (the external thread 4-1 of the first rotary joint 4 connects to the threaded hole 7-1). The stepped cylindrical surface 4-2 of the first rotary joint 4 mates with the ball bearing 9 at the bearing fixing hole 1-2. One first rotary joint 4 is connected and mated with a corresponding ball bearing 9. When the adjustment frame 7 tilts and rotates, the attitude adjustment frame 1 rotates along the axis of the first rotary joint 4, and the combined fixing seat 2, together with the detector mechanism 5, rotates along the axis of the second rotary joint 11, keeping the detector mechanism axis relatively perpendicular and still meeting the tilt requirements for normal operation.

[0050] like Figure 5As shown, circuit board 6 is fixedly connected to the upper surface of the combined mounting base 2. Circuit board 6 has several lead holes 6-1 corresponding to the positions of detector core 5 on the combined mounting base 2. The positive and negative terminals of detector core 5 can extend from the lead holes 6-1 for convenient subsequent soldering. Each lead hole 6-1 on circuit board 6 has a positive core pad 6-2 and a negative core pad 6-3. Following the sequence A, B, C, G, D, E, F, the positive core pad at the first A position is connected to the first spring 3 via a lead wire with an attached solder resist layer. The positive core pad 6-2 at each lead hole 6-1 is connected to the negative core pad 6-3 at the previous lead hole 6-1 via a lead wire with an attached solder resist layer 6-5. That is, the positive core pad at B is connected to the negative core pad at A via a lead wire with an attached solder resist layer, and the positive core pad at C is connected to the negative core pad at B via a lead wire with an attached solder resist layer. The positive electrode core pad at G is connected to the negative electrode core pad at C via a lead with an attached solder resist layer. Similarly, the positive electrode core pad at D is connected to the negative electrode core pad at G via a lead with an attached solder resist layer. The positive electrode core pad at E is connected to the negative electrode core pad at D via a lead with an attached solder resist layer. The positive electrode core pad at F is connected to the negative electrode core pad at E via a lead with an attached solder resist layer. The negative electrode core pad at F is connected to the second spring 17 via a lead with an attached solder resist layer. After soldering the seven detector cores 5, they form an electrical circuit, as shown below. Figure 10 As shown, use wire 16 to connect the positive terminal of the detector mechanism at hole A to the positive core pad. Connect the negative terminal of the detector mechanism at hole A to the negative core pad using a wire. Connect the positive terminal of the detector mechanism at hole B to the positive core pad using a wire. Connect the negative terminal of the detector mechanism at hole B to the negative core pad using a wire. Connect the positive terminal of the detector mechanism at hole C to the positive core pad using a wire. Connect the negative terminal of the detector mechanism at hole G to the positive core pad using a wire. The terminals are connected to the negative core pad via wires. The positive terminal of the detector mechanism at hole D is connected to the positive core pad, and the negative terminal of the detector mechanism at hole D is connected to the negative core pad via wires. The positive terminal of the detector mechanism at hole E is connected to the positive core pad, and the negative terminal of the detector mechanism at hole E is connected to the negative core pad via wires. The positive terminal of the detector mechanism at hole F is connected to the positive core pad, and the negative terminal of the detector mechanism at hole F is connected to the negative core pad via wires. In this way, a total of 7 detector mechanisms at holes A, B, C, G, D, E, and F are connected in series.

[0051] The negative electrode core pad at hole A and the positive electrode core pad at hole C are connected by a lead with an attached solder resist layer. A semi-circular solder joint J is provided in the middle of the lead with the attached solder resist layer. When the semi-circular solder joint J is soldered with solder wire, the detector mechanism 5 at hole B fails (the positive and negative terminals of the detector mechanism at hole B are short-circuited) and does not function in the electrical circuit.

[0052] A solder mask layer is attached to the negative electrode core pad 6-3 at hole A and the negative electrode core pad 6-2 at hole C. A semi-circular solder joint 6-4 (i.e., semi-circular solder joint L) is located in the middle of this solder mask layer lead. A solder mask layer is attached to the negative electrode core pad at hole G and the positive electrode core pad at hole G. A semi-circular solder joint M is located in the middle of this solder mask layer lead. A solder mask layer is attached to the negative electrode core pad at hole D and the positive electrode core pad at hole F. A semi-circular solder joint K is located in the middle of this solder mask layer lead. A solder mask layer is attached to the negative electrode core pad at hole D and the negative electrode core pad at hole F. A semi-circular solder joint H is located in the middle of this solder mask layer lead. Similarly, when the semi-circular solder joint K is soldered, the detector core 5 at hole E fails and does not function in the electrical circuit. Similarly, when the semicircular solder joints L, H, and M are soldered separately, the detector core 5 at holes B and C, E and F, and G respectively fails. By using semicircular solder joints, different numbers of detector cores 5 can be implemented in application cases that share the same circuit board 6, achieving a universal purpose.

[0053] The circuit board 6 has pads on both sides that are connected to the positive electrode core pad 6-2 at hole A and the negative electrode core pad 6-3 at hole F via leads with attached solder resist. A first spring 3 and a second spring 17 are also soldered onto the pads (the first spring 3 and the second spring 17 are located on both sides of the circuit board 6). The other end of the first spring 3 can be bent and placed into a cylindrical recess 2-3, and the other end of the second spring 17 can be bent and placed into a corresponding cylindrical recess.

[0054] like Figure 6 As shown, one end of the first rotary joint 4 has an external thread 4-1, and the other end has a stepped cylindrical surface 4-2. The external thread 4-1 meshes with the internal thread hole 7-1 of the adjusting bracket 7, and the stepped cylindrical surface 4-2 mates with the ball bearing 9. Simultaneously, the first rotary joint 4 has a through hole 4-3 in the middle, and an insulating sleeve 8 is installed inside the through hole 4-3. The insulating sleeve 8 has a through hole in the middle, and a contact shaft 10 (the insulating sleeve 8 is fitted onto the contact shaft 10) is installed inside the through hole. One end of the contact shaft 10 is rod-shaped, and the other end is hemispherical. One first rotary joint 4 corresponds to one contact shaft 10.

[0055] like Figure 7As shown, one end of the second rotary joint 11 has an external thread 11-1, and the other end has a stepped cylindrical surface 11-2. The external thread 11-1 engages with the internal thread hole 1-1 of the attitude adjustment frame 1, and the stepped cylindrical surface 11-2 mates with the ball bearing 9 in the bearing fixing hole 2-2. Simultaneously, the second rotary joint 11 has a contact shaft connection hole 11-3 in the middle, and an insulating sleeve 8 is installed inside the contact shaft connection hole 11-3. The insulating sleeve 8 has a through hole in the middle, and a contact shaft 10 (the insulating sleeve 8 is fitted onto the contact shaft 10) is installed inside the through hole. A circular through hole 11-4 is also provided on the side of the second rotary joint 11 at the stepped position.

[0056] The other end of the first reed 3 located in the cylindrical recess 2-3 contacts the hemispherical end of the contact shaft in the second rotary joint 11, and is electrically connected. The other end of the second reed 17 contacts the hemispherical end of the contact shaft in another second rotary joint, and is electrically connected.

[0057] In this embodiment, signals from multiple detector mechanisms are transmitted to the contact shaft 10 in the second rotary joint 11 via the first spring 3 and the second spring 17. Two signal lines are bonded together with adhesive in an annular groove 1-3. One end of the first signal line passes through the circular through-hole 11-4 of the first second rotary joint 11 and is welded to the round rod-shaped end of the contact shaft 10, thus establishing communication with the first spring 3. The other end of the first signal line is welded to the third spring 18 at one of the first rotary joints 4. The third spring 18 makes sliding contact with the hemispherical end of the contact shaft 10 in the first rotary joint 4.
