Description

Technical Field

[0001] The utility model relates to the field of mechanical transmission devices, and particularly to a radar navigation fixed remote control automatic lock. Background Art

[0002] The guns of a warship need a radar as an "eye" to aim at targets. When the radar is working, it is controlled by a servo system to rotate in the vertical and horizontal directions to track targets; in the non-working mode (such as sailing in the non-combat mode), the servo system of the radar does not work. At this time, the radar can freely rotate in the vertical and horizontal directions. When the warship is sailing at sea, it will sway with the waves, and the radar will also freely rotate in the vertical and horizontal directions. To prevent the radar from rotating, generally a mechanical latch is designed in each of the vertical and horizontal directions of the radar; when entering the combat mode, the soldier needs to climb from the control room to the radar of the gun on the deck to pull out the latch, and then let the servo system control the rotation of the gun radar.

[0003] Since it takes time for the soldier to climb from the control room to the deck, it affects the timely locking of the target by the gun, delays the fighter opportunity, and at the same time, when the weather is bad, there is a safety risk for the soldier to operate on the deck. Therefore, it is crucial to design a remotely controllable automatic lock. Summary of the Utility Model

[0004] Aiming at the problems in the prior art that the radar will move freely with the waves during the navigation of the warship, and when the weather is bad, there is a safety risk for the soldier to manually unlock the radar on the deck, the utility model provides a radar navigation fixed remote control automatic lock to solve the above problems.

[0005] The present application provides a radar navigation fixed remote control automatic lock for locking the rotation direction of the radar, including an operation switch arranged in the control room of the warship and a fixed seat locked on the radar. A cavity for accommodating a locking member is formed in the fixed seat; the end of the locking member protrudes from the bottom of the fixed seat, a relay is arranged inside the fixed seat to cooperate with the locking member and control the up and down movement of the locking member, and the operation switch is electrically connected to the relay. The end of the locking member is detachably matched with a fixing hole on the radar.

[0006] By adopting the above technical solution, the on / off of the relay is controlled by the operation switch, and then the movement of the locking member is controlled to realize the remote control operation of locking / unlocking the locking member and the fixing hole, so as to avoid the situation that the radar moves freely with the waves when the warship sails freely. At the same time, the relay is used for control, which can quickly respond to the operation instruction and improve the working efficiency of the automatic lock.

[0007] In some specific embodiments, the locking member successively includes a first latch portion, a second latch portion and a lock tongue portion from top to bottom. The relay cooperates with the first latch portion, and the lock tongue portion is detachably matched with the fixing hole.

[0008] By adopting the above technical solution, the locking member has a simple structural distribution, can be adapted to different types of radars, has strong versatility, and enables the automatic lock to be applied to various scenarios where locking is required.

[0009] In some specific embodiments, the top end of the first locking bolt portion protrudes from the top of the fixed seat, and a support portion is provided closely adjacent to the first locking bolt portion on the top of the fixed seat.

[0010] By adopting the above technical solution, the design of the support portion can effectively prevent the first locking bolt portion from shifting, and at the same time provides additional protection and support for the first locking bolt portion.

[0011] In some specific embodiments, an emergency handle is further sleeved on the support portion, and the emergency handle and the support portion are in clearance fit.

[0012] By adopting the above technical solution, the automatic lock can have the function of manual unlocking. The clearance fit between the emergency handle and the support portion enables the emergency handle to move smoothly on the support portion, thereby reducing the force required to manually pull up the emergency handle and facilitating quick manual unlocking.

[0013] In some specific embodiments, the emergency handle sequentially includes a force application portion and a sleeve portion from top to bottom. The size of the force application portion is larger than that of the sleeve portion, and a handle bolt passes through and fixes the center of the force application portion at the top end of the first locking bolt portion.

[0014] By adopting the above technical solution, the force application portion provides a point for easily applying force to the operation of manually pulling up the emergency handle, which is convenient for gripping and can ensure that there is no sliding or displacement during operation, facilitating soldiers to quickly find the emergency handle for unlocking operation in bad weather.

[0015] In some specific embodiments, a trigger sensing device is further included. The trigger sensing device includes a trigger switch fixedly arranged on the outer side of the fixed seat and a signal trigger rod. One end of the signal trigger rod is in sliding fit with the trigger switch.

[0016] By adopting the above technical solution, the trigger sensing device is used to detect the unlocking / locking state of the locking member, and the trigger switch is used to provide an unlocking signal to the servo system of the radar, enabling the servo system to quickly control the radar to enter the wartime state. At the same time, it can also prevent the mechanical structures such as the motor and related connected gears in the servo system from being damaged when the servo system forcibly controls the movement of the radar and the automatic lock is jammed in the fixing hole when the radar is not unlocked.

[0017] In some specific embodiments, the other end of the signal trigger rod is in interference fit, bolt fit or welding fit with the second locking bolt portion.

[0018] By adopting the above scheme, the interference fit and bolt fit enable the signal trigger rod to be detachably fitted with the second locking bolt part, which is convenient for disassembly, maintenance and adaptation to different application scenarios. The welding fit can ensure a strong connection between the signal trigger rod and the second locking bolt part, guarantee the stability of the connection, and is not easily damaged even under the condition of high working frequency and long working time of the automatic lock, thus improving the overall service life of the automatic lock.

[0019] In some specific embodiments, an installation platform is formed around the trigger switch on the outer side of the fixed seat, and a cover plate is fixed on the installation platform through cover plate bolts. The cover plate and the installation platform cooperate to form a protection cavity for accommodating the trigger switch.

[0020] By adopting the above technical scheme, the protection cavity formed by the cover plate and the installation platform provides an additional protection structure for the trigger switch, avoiding the problems that the internal components and circuits are corroded and fail or are damaged after the trigger switch is exposed to the marine air for a long time.

[0021] In some specific embodiments, the relay includes a coil and a return spring, and the coil is disposed around the first locking bolt part.

[0022] By adopting the above technical scheme, the movement control of the locking part is realized through the magnetic field change caused by the energization and de-energization of the coil. At the same time, when the coil is de-energized, the return spring can quickly reset the locking part to the locked state, effectively improving the response efficiency of the automatic lock.

[0023] In some specific embodiments, a sealing ring is disposed around the lock tongue part at the bottom of the fixed seat.

[0024] By adopting the above technical scheme, the lock tongue part and the fixed seat are isolated by the sealing ring. This sealing ring needs to play a lubricating role and a sealing role. The lubricating role is to ensure that the friction coefficient between the lock tongue part and the fixed seat is small when the lock tongue part moves up and down, and the sealing role is to ensure that the structure arranged inside the fixed seat is not directly exposed to the marine air.

[0025] This application mainly solves the problems in the prior art that when a ship is sailing, the radar will move freely with the waves, and when the weather is bad, there is a safety risk for soldiers to manually unlock the radar on the deck. This application proposes a fixed remote control automatic lock for radar navigation. By combining remote control and manual emergency functions, it realizes the effective locking and unlocking of the vertical and horizontal movements of the radar. Inside the automatic lock, the cooperation between the locking part and the relay ensures a reliable locking state. At the same time, the signal trigger rod and the trigger switch are set to monitor the locking state in real time, avoiding mechanical damage caused by forced control. The design of the support part and the emergency handle improves the stability and convenience of operation. Especially in bad weather, the convenient grip of the handle greatly reduces the force required for manual unlocking. In addition, the application of the sealing ring effectively protects the internal structure and extends the service life. Generally speaking, the structure of this automatic lock is simple and universal, adapting to a variety of radar application scenarios, improving the safety, reliability and maintenance convenience of the system.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In the following detailed description, reference is made to the accompanying drawings, which form a part of the detailed description and illustrate illustrative specific embodiments in which the present utility model can be practiced. In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the described figures. Since the components of the embodiments can be positioned in several different orientations, the directional terms are used for the purpose of illustration and are in no way limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present utility model. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present utility model is defined by the appended claims.

[0031] This application proposes a radar navigation fixed remote control automatic lock for locking the rotation direction of the radar. Figure 1 The structural schematic diagram of the radar navigation fixed remote control automatic lock according to an embodiment of the present utility model is shown. As shown in the figure, the automatic lock includes an operation switch (not shown in the figure) provided in the ship control room, and a fixed seat 01 locked on the radar (not shown in the figure). A cavity for accommodating a locking member 02 is formed in the fixed seat 01; the end of the locking member 02 protrudes from the bottom of the fixed seat 01, and a relay (not shown in the figure) cooperates with the locking member 02 inside the fixed seat 01 to control the up and down movement of the locking member 02, and the operation switch is electrically connected to the relay. The end of the locking member 02 is detachably engaged with the fixing hole 03 on the radar.

[0032] Specifically, in order to control the movement of the radar in the vertical and horizontal directions simultaneously, an automatic lock is provided in each of the vertical and horizontal directions of the radar. At the same time, the automatic lock can be remotely controlled. By setting an operation switch in the ship control room, the on and off of the relay is controlled by the operation switch. When the relay is energized, the locking member 02 moves upward under the action of electromagnetic force, so that the end of the locking member 02 is disengaged from the fixing hole 03, enabling the radar to move freely in the vertical and horizontal directions. When the relay is de-energized, the locking member 02 drops and snaps into the fixing hole 03, thereby restricting the movement of the radar.

[0033] In a specific embodiment, the locking member 02 sequentially includes a first locking bolt portion 021, a second locking bolt portion 022, and a locking tongue portion 023 from top to bottom. The relay cooperates with the first locking bolt portion 021, and the locking tongue portion 023 is detachably engaged with the fixing hole 03. The locking member 02 has a simple structural distribution, can adapt to different types of radars, and has strong versatility, enabling the automatic lock to be applied to various scenarios requiring locking.

[0034] In a specific embodiment, the top end of the first bolt portion 021 protrudes from the top of the fixed seat 01. A support portion 011 is provided close to the first bolt portion 021 on the top of the fixed seat 01. The design of the support portion 011 can effectively prevent the first bolt portion 021 from shifting, and at the same time provides additional protection and support for the first bolt portion 021.

[0035] In a specific embodiment, an emergency handle 04 is also sleeved on the support portion 011, and the emergency handle 04 and the support portion 011 are in clearance fit. When the relay controls the locking member 02 to move up and down, the emergency handle 04 is always sleeved on the support portion 011, ensuring that the locking member 02 is not completely exposed to the marine air. The setting of the emergency handle 04 enables the automatic lock to have the function of manual unlocking. The clearance fit between the emergency handle 04 and the support portion 011 allows the emergency handle 04 to move smoothly on the support portion 011, thereby reducing the force required to manually pull up the emergency handle 04, which is beneficial for quick manual unlocking. When the remote control function fails to work for other reasons, the soldier can go to the upper deck and manually pull up the emergency handle 04 to immediately unlock the radar and enter the wartime state. Specifically, with the clearance fit between the emergency handle 04 and the support portion 011, the emergency handle 04 can still be sleeved on the support portion 011 in the unlocked state and the locked state, ensuring that the locking member 02 is not completely exposed to the marine air.

[0036] In a specific embodiment, the emergency handle 04 sequentially includes a force application portion 041 and a sleeve portion 042 from top to bottom. The size of the force application portion 041 is larger than that of the sleeve portion 042, which is convenient for manually pulling up the emergency handle 04. The handle bolt 043 passes through and fixes the center of the force application portion 041 at the top end of the first bolt portion 021. The force application portion 041 provides a point for applying force for manually pulling up the emergency handle 04, which is convenient for gripping and can also ensure that there is no sliding or displacement during operation, facilitating the soldier to quickly find the emergency handle 04 for unlocking operation in bad weather.

[0037] In a specific embodiment, a trigger sensing device 05 is further included. The trigger sensing device 05 includes a trigger switch 051 fixed on the outside of the fixed seat 01 and a signal trigger rod 052. One end of the signal trigger rod 052 is in sliding fit with the trigger switch 051. The trigger sensing device 05 is used to detect the unlocked / locked state of the locking member 02, and the trigger switch 051 is used to provide an unlocking signal to the servo system of the radar, enabling the servo system to quickly control the radar to enter the wartime state. At the same time, it can also prevent the mechanical structures such as the motor and related connected gears in the servo system from being damaged when the servo system forcibly controls the radar to move when the radar is not unlocked, resulting in the automatic lock being stuck in the fixing hole 03.

[0038] In a specific embodiment, the other end of the signal trigger rod 052 and the second locking bolt portion 022 are in interference fit, bolt fit or welding fit. Specifically, a hole is opened in the second locking bolt portion 022 corresponding to the position of the trigger switch 051. The other end of the signal trigger rod 052 is fixed in the hole by interference fit or bolts, or directly welded to the second locking bolt portion 022. The interference fit and bolt fit methods enable the signal trigger rod to be detachably fitted with the second locking bolt portion, facilitating disassembly, maintenance and adaptation to different application scenarios. The welding fit can ensure a strong connection between the signal trigger rod and the second locking bolt portion, guaranteeing the stability of the connection and making it not easily damaged even when the automatic lock has a high working frequency and a long working time, which can improve the overall service life of the automatic lock.

[0039] Specifically, when the locking tongue portion 023 is inserted into the fixing hole 03 of the radar, the signal trigger rod 052 moves downward with the second locking bolt portion 022, and the trigger switch 051 is not triggered, so the signal is invalid. When the locking tongue portion 023 leaves the fixing hole 03, the signal trigger rod 052 moves upward with the second locking bolt portion 022, and the trigger switch 051 is triggered, so the signal is valid.

[0040] In a specific embodiment, an installation platform 012 is formed outside the fixing base 01 around the trigger switch 051. A cover plate 06 is fixed on the installation platform 012 by cover plate bolts 061. At the same time, the cover plate bolts 061 need to be treated with flat washers or fuses to prevent loosening and detachment. The cover plate 06 and the installation platform 012 cooperate to form a protection cavity for accommodating the trigger switch, providing an additional protection structure for the trigger switch 051 by the protection cavity formed by the cover plate 06 and the installation platform 012, and avoiding the problems that the internal components and circuits are corroded and fail or are damaged after the trigger switch 051 is exposed to the marine air for a long time.

[0041] In a specific embodiment, the relay includes a coil 07 and a return spring (not shown in the figure) inside the relay. The coil 07 is arranged around the first locking bolt portion 021, and the movement of the locking member 02 is controlled by the magnetic field change of the coil 07 when it is energized and de-energized. At the same time, when the coil 07 is de-energized, the return spring can quickly reset the locking member 02 to the locked state, effectively improving the response efficiency of the automatic lock.

[0042] In a specific embodiment, a sealing ring 08 is arranged around the locking tongue portion 023 at the bottom of the fixing base 01. The locking tongue portion 023 and the fixing base 01 are isolated by the sealing ring 08. This sealing ring 08 needs to play a lubricating role and a sealing role. The lubricating role is to ensure that the friction coefficient between the locking tongue portion 023 and the fixing base 01 is small when the locking tongue portion 023 moves up and down, and the sealing role is to ensure that the structure arranged inside the fixing base 01 is not directly exposed to the marine air.

[0043] In this application, the remote control function of the automatic lock is realized by setting an operation switch in the control room of the ship. After the automatic lock is powered on, the coil 07 of the relay is energized, and the first locking bolt part 021 moves upward under the action of electromagnetic force. As a result, the second locking bolt part 022 drives the signal trigger rod 052 to move upward, and the locking tongue part 023 disengages from the fixing hole 03 of the radar, allowing the radar to rotate freely. The signal trigger rod 052 causes the trigger switch 051 to trigger a lock-opening feedback signal. After receiving the lock-opening feedback signal, the servo system of the radar controls the radar to enter the wartime state;

[0044] In the standby state, the servo system of the radar controls the radar to rotate to the zero position. In the control room, the operation switch is used to cut off the power supply to the coil 07 of the relay. The first locking bolt part 021 is disengaged from the action of electromagnetic force and moves downward under the action of the return spring inside the relay, driving the locking tongue part 023 and the signal trigger rod 052 to move downward. The locking tongue part 023 is inserted into the fixing hole 03, and the radar is locked and cannot rotate freely.

[0045] This application mainly solves the problems in the prior art that the radar on the ship will move freely with the waves during navigation, and there is a safety risk for soldiers to manually unlock the radar on the deck in bad weather. This application proposes a radar navigation fixed remote control automatic lock. By combining remote control and manual emergency functions, effective locking and unlocking of the vertical and horizontal movements of the radar are achieved. Inside the automatic lock, the cooperation between the locking part 02 and the relay ensures a reliable locking state. At the same time, the setting of the signal trigger rod 052 and the trigger switch 051 can monitor the locking state in real time, avoiding mechanical damage caused by forced control. The design of the support part 011 and the emergency handle 04 improves the stability and convenience of operation. Especially in bad weather, the convenient grip of the emergency handle 04 greatly reduces the force required for manual unlocking. In addition, the application of the sealing ring 08 effectively protects the internal structure and extends the service life. Generally speaking, the structure of this automatic lock is simple and universal, adapting to a variety of radar application scenarios, improving the safety, reliability and maintenance convenience of the system.

In this way, if these modifications and changes are within the scope of the claims of the present invention and their equivalent forms, the present invention also aims to cover these modifications and changes.
