attitude switch

Abstract

This invention discloses an attitude switch. By incorporating an eccentric weight, the switch utilizes the change in detector attitude from vertical to horizontal. The eccentric weight, under the influence of gravity, drives the connecting shaft to rotate, moving it from the first control slot into the second control slot. This further releases the limiting effect of the positioning component on the push rod within the attitude switch, causing the push rod to actuate under the action of the elastic component. This actuates the toggle switch, completing its switching function and enabling data erasure. The switch features stable performance and high reliability. It can quickly activate when the detector attitude changes, triggering the self-destruct mechanism within the detector and effectively preventing the loss of technology carried by the detector.

Description

Technical Field

[0001] This invention relates to the field of underwater detectors, and more particularly to an attitude switch. Background Technology

[0002] With the increasing number of underwater probes, some probes often remain submerged for up to six months to collect comprehensive underwater data or conduct other experimental activities. Due to the complex and ever-changing underwater environment, the mooring locks often break or the probes are intentionally retrieved during underwater operations. These actions frequently lead to the loss of data and the risk of leakage of advanced detection technologies from the probes.

[0003] Some modern underwater vehicles are programmed with a set operating time before launch, which is then automatically destroyed by water intake upon reaching the set time, thus erasing data. Other vehicles have a data erasure device activated by a cover; removing the cover triggers the device to erase data. While these devices can effectively erase data and protect technology from leakage to some extent, they also pose significant risks. If the vehicle unexpectedly surfaces during its operating time, or if salvage personnel fail to remove the cover associated with the erasure device, the device will become ineffective.

[0004] There is currently no effective solution to the problem that existing technologies cannot quickly protect data or erase data in a timely manner. Summary of the Invention

[0005] To solve the above problems, the present invention provides an attitude switch that utilizes the change of the detector's attitude from vertical to horizontal to cause the weight to rotate the connecting shaft under the action of gravity, thereby releasing the internal limit and causing the push rod to move under the action of the elastic element, which in turn pushes the toggle switch to complete the switch function.

[0006] To achieve the above objectives, this invention provides an attitude switch disposed in a detector, with its axis perpendicular to the detector's axis. The switch includes: a fixed cylinder comprising a first fixed end and a second fixed end opposite to each other; the first fixed end being inserted into and connected to a control rod; and a push rod inserted into the second fixed end; the fixed cylinder having at least one mounting slot on its side wall near the second fixed end for mounting a positioning element; the control rod comprising a first control slot and a second control slot connected by a connecting slot; the second control slot being closer to the fixed cylinder than the first control slot; a base, the inner wall of which is connected to the outer wall of the fixed cylinder; and the push rod comprising a main body inserted into the fixed cylinder and a pushing part located inside the base; an elastic element sleeved on the outer side of the main body, the elastic element being formed by the positioning element and the base. The push part has an inclined surface facing the second fixed end; a toggle switch has its actuating lever passing through the side wall of the base and contacting the inclined surface of the push part; a sleeve is fitted around the control rod and the outside of the fixed cylinder; a ring is located in the space between the sleeve and the fixed cylinder and connected to the sleeve, and in the initial state, together with the push rod, fixes the mounting and positioning component in the mounting groove; a connecting shaft has one end passing through one side of the sleeve, the control rod, and the other side of the sleeve, and the other end located outside the sleeve. A weight is fixed at each end of the connecting shaft. The part of the connecting shaft inside the control rod is located in the first control groove in the initial state. When the posture changes, it can enter the second control groove through the connecting groove to release the positioning component's limitation on the elastic component, so that the push part pushes the actuating lever to open the toggle switch.

[0007] Optionally, the control rod has a first groove on its side wall; the sleeve has a second groove at a position corresponding to the first groove; when the first groove and the second groove are at the same position, the control rod and the sleeve are fixed by a safety fork.

[0008] Further optionally, the connecting shaft includes a flat portion and two connecting portions extending from the flat portion to both sides; the flat portion is a flat plate structure, and when rotated to the point where its plane is parallel to the plane of the communicating groove, the flat portion moves from the first control groove to the second control groove; the two connecting portions extend from both sides of the control rod respectively, and each connecting portion is fitted with a weight; the weight is connected to the corresponding connecting portion by screws.

[0009] Alternatively, the side wall of the fixed cylinder is provided with four mounting slots, which are evenly distributed in the circumferential direction of the side wall of the fixed cylinder.

[0010] Alternatively, the positioning element may be a steel ball.

[0011] Optionally, the outer wall of the main body of the push rod is provided with a baffle, which is limited by the positioning member in the initial state; the base is provided with a radially extending stop; and the elastic member is provided between the baffle and the stop.

[0012] Alternatively, the elastic element may be a spring, which is in a compressed state in the initial state.

[0013] Further optionally, the control rod is fixed to the fixed cylinder by screws; the ring is fixed to the sleeve by screws.

[0014] Optionally, the space between the sleeve and the fixed cylinder can accommodate the positioning element.

[0015] Alternatively, both the first control slot and the second control slot can be cylindrical through holes.

[0016] The above technical solution has the following beneficial effects: The embodiment of the present invention designs an eccentric weight, which utilizes the change of the detector's attitude from vertical to horizontal to achieve the rotation of the connecting shaft under the action of gravity, thereby releasing the position restriction in the attitude switch, causing the push rod to move under the action of the elastic element, and pushing the toggle switch to complete the switch function. It has the characteristics of stable performance and high reliability. When the detector's attitude changes, it can act quickly, thereby activating the self-destruct device in the detector and effectively preventing the loss of the technology carried by the detector.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides an attitude switch, disposed in a detector, with its axis perpendicular to the detector's axis, such as... Figure 1 , Figure 2As shown, the attitude switch includes: a fixed cylinder 6, which includes a first fixed end and a second fixed end opposite to each other. The first fixed end is connected to the control rod 5 after being inserted into it. A push rod 7 is inserted into the second fixed end. At least one mounting slot is provided on the side wall of the fixed cylinder 6 near the second fixed end for mounting the positioning member 8. The control rod 5 includes a first control slot 502 and a second control slot 503, which are connected by a connecting slot 501. The second control slot 503 is closer to the fixed cylinder 6 than the first control slot 502. A base 1 is provided, with its inner wall connected to the outer wall of the fixed cylinder 6. The push rod 7 includes a main body that is inserted into the fixed cylinder 6 and a pushing part located inside the base 1. An elastic member 9 is sleeved on the outside of the main body. The elastic member 9 is limited by the positioning member 8 and the base 1. The side of the pushing part facing the second fixed end is... Inclined surface; Toggle switch 11, the toggle lever of the toggle switch 11 passes through the side wall of the base 1 and contacts the inclined surface of the push part; Sleeve 2, sleeved on the outside of the control lever 5 and the fixed cylinder 6; Ring 13, the ring 13 is located in the space between the sleeve 2 and the fixed cylinder 6 and is connected to the sleeve 2, and in the initial state, together with the push rod 7, it fixes the mounting positioning member 8 in the mounting groove; Connecting shaft 4, one end of the connecting shaft 4 passes through one side of the sleeve 2, the control lever 5 and the other side of the sleeve 2 in sequence, and the other end is located on the outside of the sleeve 2. A weight 3 is fixed at each end of the connecting shaft 4. The part of the connecting shaft 4 located inside the control lever 5 is located in the first control groove 502 in the initial state. When the posture changes, it can enter the second control groove 503 through the connecting groove 501 to release the positioning member 8 from the limit of the elastic member 9 and then push the toggle lever to the toggle switch 11 to open.

[0029] like Figure 1 As shown in the diagram, the horizontal direction is the axis of the attitude switch, which is perpendicular to the axis of the underwater probe. In the initial state, when the underwater probe is vertically moored underwater, the attitude switch is set horizontally, meaning its axis is horizontal.

[0030] like Figure 1 , Figure 2 As shown, in the initial state, the control rod 5 is inserted into one end of the fixed cylinder 6, the sleeve 2 is fitted over the outside of the control rod 5 and the fixed cylinder 6, and the ring 13 is located between the sleeve 2 and the fixed cylinder 6. The control rod 5 and the fixed cylinder 6, and the sleeve 2 and the ring 13 are respectively fixedly connected.

[0031] The connecting shaft 4 is inserted into the round hole on one side of the sleeve 2 and passes through the first control groove 502 of the control rod 5, and finally exits from the other side of the sleeve 2. A weight 3 is fixed at each end of the connecting shaft 4.

[0032] At least one mounting slot is provided on the side wall of the fixed cylinder 6, in which a positioning element 8 is mounted. The positioning element 8 is positioned by an outer ring 13 and an inner push rod 7. The push rod 7 is inserted into the fixed cylinder 6 from the other end, and an elastic element 9 is sleeved on its outer side. The inner wall of the base 1 near one end is connected to the other end of the fixed cylinder 6, thus accommodating the push rod 7 in the cavity of the fixed cylinder 6 and the cavity of the base 1. At this time, the positioning element 8 and the inner wall of the base 1 together limit the push rod 7, preventing it from actuating the toggle switch 11. The toggle switch 11 is mounted on the base 1, and the toggle lever extends into the interior of the base 1. The toggle switch 11 is also connected to a data erasure device, which erases the data of the underwater detector when the switch is turned on.

[0033] Specifically, the push rod 7 includes a main body and a pushing part. The main body is located in the inner cavity of the fixed cylinder 6, and the pushing part is located in the inner cavity of the base 1. The pushing part includes an inclined surface. In the initial state, the pushing part contacts the toggle lever of the toggle switch 11 without affecting it.

[0034] As an alternative implementation, the base 1 is screwed onto the wall of the fixed cylinder 6 via a threaded connection.

[0035] Figure 3 The initial state diagram of the weight 3 and the connecting shaft 4 provided in this embodiment of the invention is as follows: Figure 3 As shown, in the initial state, that is, when the detector is vertically moored underwater, the attitude switch is placed horizontally inside the detector, the axis of the attitude switch is in the horizontal direction and perpendicular to the mooring direction of the detector, the center of mass of the weight 3 is at the bottom under the action of gravity, the line connecting the weight 3 and the center of mass of the weight is perpendicular to the axis of the attitude switch, and the connecting shaft 4 cannot move laterally under the drive of the weight 3, so it cannot move from the first control slot 502 to the second control slot 503.

[0036] Figure 4 A schematic diagram of the cross-sectional structure of the attitude switch after attitude change provided in this embodiment of the invention is shown below. Figure 4 As shown, when the detector encounters an unexpected situation and changes from a vertical to a horizontal state, the attitude switch rotates with the detector, and the axis of the attitude switch is vertical, perpendicular to the detector's axis. Combined with... Figure 5 It can be seen that under the action of gravity, the weight 3 drives the connecting shaft 4 to rotate in the first control groove 502. After rotation, the connecting shaft 4 can move from the first control groove 502 to the second control groove 503. At this time, the sleeve 2 moves down, the ring 13 no longer limits the positioning part 8, the positioning part 8 falls out of the mounting groove, and under the action of the elastic part 9, the push rod 7 moves up, and the pushing part pushes the toggle lever of the toggle switch 11 to complete the opening of the switch.

[0037] As an optional implementation, the control lever 5 has a first groove on its side wall; the sleeve 2 has a second groove at a position corresponding to the first groove; when the first groove and the second groove are in the same position, the control lever 5 and the sleeve 2 are fixed by the safety fork 10.

[0038] like Figure 2 As shown, when the attitude switch is not assembled to the detector, a safety structure needs to be installed. In this embodiment, corresponding grooves are provided on both the sleeve 2 and the control rod 5, and the relative positions of the two are fixed by the safety fork 10. After it is installed to the detector, the safety fork 10 is removed, thereby ensuring that the attitude switch does not malfunction when its placement state changes during the installation process.

[0039] As an optional implementation method, such as Figure 6 As shown, the connecting shaft 4 includes a flat portion 401 and two connecting portions 402 extending from the flat portion 401 to both sides; the flat portion 401 has a flat plate structure, and when rotated to the point where its plane is parallel to the plane of the connecting groove 501, the flat portion 401 moves from the first control groove 502 to the second control groove 503; the two connecting portions 402 extend from both sides of the control rod 5 respectively, and each connecting portion 402 is fitted with a weight 3; the weight 3 is connected to the corresponding connecting portion 402 by screws 12.

[0040] like Figure 6 As shown, the connecting shaft 4 has a flat, plate-shaped portion 401 in the middle and connecting portions 402 on both sides. The flat portion 401 is initially placed in the first control groove 502, as... Figure 3 , Figure 6 , Figure 7 As shown, the weight 3 is positioned at the bottom under the action of gravity. The line connecting the weight 3 and the center of mass of the weight is perpendicular to the axis of the attitude switch. Under the action of the weight 3, the flat surface of the flat part 401 of the connecting shaft 4 is perpendicular to the axis of the control rod 5, that is, perpendicular to the plane of the connecting groove 501. At this time, the connecting shaft 4 cannot enter the second control groove 503 from the first control groove 502.

[0041] like Figure 5 , Figure 6 , Figure 7 As shown, after the attitude change, the weight 3 drives the connecting shaft 4 to rotate in the first control groove 502 under the action of gravity, so that the flat surface of the flat part 401 is parallel to the plane where the connecting groove 501 is located, and moves from the first control groove 502 to the second control groove 503 under the action of gravity.

[0042] As an optional implementation, the side wall of the fixing cylinder 6 is provided with four mounting slots, which are evenly distributed in the circumferential direction of the side wall of the fixing cylinder 6.

[0043] To improve the reliability of the limit, this embodiment provides four positioning elements 8 on the side wall of the fixed cylinder 6, which are respectively installed in the corresponding mounting slots. The four mounting slots are evenly distributed on the side wall of the fixed cylinder 6.

[0044] As an optional implementation, the positioning element 8 is a steel ball.

[0045] As an optional implementation, the outer wall of the main body of the push rod 7 is provided with a baffle, which is limited by the positioning member 8 in the initial state; the base 1 is provided with a radially extending block; and the elastic member 9 is provided between the baffle and the block.

[0046] To limit the position of the push rod 7, this embodiment provides a baffle on the outer side of the main body of the push rod 7. One side of the baffle is limited by the positioning member 8, and the other end is connected to or in contact with the elastic member 9. A stop is also provided inside the base 1, and the other end of the elastic member 9 is connected to or in contact with the stop to complete the initial positioning of the push rod 7.

[0047] After the posture changes, the positioning part 8 falls out of the mounting slot, and the push rod 7 moves along the axis toward the first fixed end of the fixed cylinder 6 under the elastic force of the elastic part 9, thereby driving the pushing part to act on the toggle lever, so that the toggle switch 11 is turned on.

[0048] As an optional implementation, the elastic element 9 is a spring, which is in a compressed state in the initial state.

[0049] In the initial state, the spring is in a compressed state to store elastic potential energy. After the attitude changes, it pushes the push rod 7 to move.

[0050] As an optional implementation, the control lever 5 is fixed to the fixed cylinder 6 by screws 12; the ring 13 is fixed to the sleeve 2 by screws 12.

[0051] As an optional implementation, the space between the sleeve 2 and the fixed sleeve 6 can accommodate the positioning element 8.

[0052] After the positioning component 8 falls off, it enters the space between the sleeve 2 and the fixed sleeve 6, and will not fall out of the entire attitude switch.

[0053] As an optional implementation method, such as Figure 7 As shown, both the first control slot 502 and the second control slot 503 are cylindrical through holes.

[0054] The installation method of the attitude switch is as follows: Insert the control rod into the fixed cylinder, put the sleeve on the ring, and connect them with screws. Insert the control rod into the sleeve, and insert the safety fork into the grooves on the sleeve and control rod. Insert the connecting shaft into the round hole at the upper end of the sleeve, pass through the first control groove on the control rod, and exit from the other end of the sleeve. Put two weights on both ends of the connecting shaft respectively, and fix the weights to the connecting shaft with screws. Insert four steel balls into the four round holes at the lower end of the fixed cylinder respectively, insert the push rod from the lower end of the fixed cylinder, and put the spring on the push rod. Screw the base onto the fixed cylinder with a threaded connection, and install the toggle switch on the base, making sure that the top of the toggle switch is in contact with the inclined surface of the push rod.

[0055] The above technical solution has the following beneficial effects: The embodiment of the present invention designs an eccentric weight, which utilizes the change of the detector's attitude from vertical to horizontal to achieve the rotation of the connecting shaft under the action of gravity, thereby releasing the position restriction in the attitude switch, causing the push rod to move under the action of the elastic element, and pushing the toggle switch to complete the switch function. It has the characteristics of stable performance and high reliability. When the detector's attitude changes, it can act quickly, thereby activating the self-destruct device in the detector and effectively preventing the loss of the technology carried by the detector.

It should be understood that the above content is only for specific embodiments of the invention and is not intended to limit the scope of protection of the invention.
