Description

Technical Field

[0001] This utility model relates to the technical field of artillery recoil timing, and in particular to an artillery recoil recovery timing device. Background Technology

[0002] There are two main existing methods for determining the recoil time of artillery: one is for the measurement personnel to stand outside the test equipment and use a stopwatch to measure the time from the start of the artillery firing to the end of the recoil recovery. This method has a high risk of inaccurate measurement due to the large human factor involved. The other method is to install a fixed high-speed camera in a suitable location inside the equipment and then watch and edit the video recordings to extract the time from the start of the artillery firing to the end of the recoil recovery, and calculate the recoil time. This method is time-consuming and has requirements for the equipment structure. If there is no suitable location to install a fixed high-speed camera, this method cannot be used.

[0003] Therefore, there are relatively few methods for measuring the recoil of artillery pieces nowadays, and the internal structure of each type of artillery piece is different, requiring more flexible installation methods. Utility Model Content

[0004] The purpose of this invention is to improve upon the existing methods for measuring the recoil of artillery, which are limited in variety and lack flexibility in installation, and to provide a recoil timing device for artillery.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The recoil timing device for artillery includes: a reflective film, an infrared sensor, an adjuster, and a cradle. The cradle is mounted on one side of the gun barrel, the reflective film is mounted on the gun barrel, the infrared sensor is mounted on the first end of the adjuster, the second end of the adjuster is mounted on the cradle, and the emitting end of the infrared sensor faces the reflective film.

[0007] The gun barrel has at least a first movable position, in which the infrared sensor emits light to the reflective film and receives the reflected light from the reflective film;

[0008] The regulator includes a first adjustment component, a second adjustment component, and a third adjustment component. The infrared sensor is mounted on the first adjustment component. In a first direction, the first adjustment component and the second adjustment component are movably coupled. In a second direction, the second adjustment component and the third adjustment component are movably coupled. The third adjustment component is mounted on the cradle.

[0009] In one embodiment, the first adjustment component includes a first support member, a first fastener, and a second support member. The first support member is bent, and the infrared sensor is installed at a first end of the first support member. The second end of the first support member has a plurality of first adjustment holes distributed in a first direction. The second support member has a first through hole corresponding to any one of the first adjustment holes. Both the first through hole and the first adjustment hole allow the first fastener to pass through. The first support member is fixed to the second support member by the first fastener.

[0010] In one embodiment, the second support member includes a first clamping plate, a second clamping plate, and a through hole formed on the first clamping plate and the second clamping plate. The first clamping plate and the second clamping plate are fixedly connected at their first ends, and a first slot is formed between the second ends of the first clamping plate and the second clamping plate. The first support member is at least partially located in the first slot and abuts against the first clamping plate and the second clamping plate.

[0011] In one embodiment, the first support member includes a first support plate, a second support plate, and a second fastener. The first support plate and the second support plate are an integral structure and are arranged perpendicularly to each other. The infrared sensor is fixed to the first support plate by the second fastener, and a plurality of the first adjustment holes are formed on the second support plate.

[0012] In one embodiment, each of the first adjustment holes is a waist-shaped hole, and the length of the first adjustment hole is greater than the outer diameter of the first fastener.

[0013] In one embodiment, the second adjustment component includes a support column, a first adjustment rod, and a third fastener. The support column includes two adjustment blocks with a second slot between them. The length of the second slot is greater than the width of the second support member. The second support member is installed in the second slot and slides in the second slot in a second direction. The third fastener is installed on either adjustment block and is used to adjust the size of the second slot.

[0014] In one embodiment, each of the adjusting blocks has a through slot, and the openings of the through slots of two adjusting blocks correspond to each other and form a second through hole located on the second slot. The second through hole allows the first end of the first adjusting rod to pass through, and the second end of the first adjusting rod is fixedly connected to the second support member.

[0015] In one embodiment, the third adjustment assembly includes a second adjustment rod, a first bolt, and a second bolt. The support column is sleeved on the second adjustment rod and slides with it. The first bolt and the second bolt are both threadedly connected to the second adjustment rod, and the support column is located between the first bolt and the second bolt.

[0016] In one embodiment, the third adjustment assembly further includes a mounting block, a third support plate, and a fourth fastener. The second adjustment rod is mounted on the third support plate, and the mounting block is mounted on the cradle. The third support plate has a second adjustment hole. One end of the fourth fastener passes through the second adjustment hole and is threadedly connected to the mounting block. The other end of the fourth fastener abuts against the third support plate.

[0017] In one embodiment, the mounting block is at least partially made of a magnetic material.

[0018] The technical solution provided by this utility model has the following advantages and effects:

[0019] On the one hand, when the cannon is fired, the cannon body moves backward, resulting in a first moving position and a second moving position. In the first moving position, the infrared sensor emits light to the reflective film and receives the reflected light from the reflective film. When the cannon body moves to the second moving position, the infrared sensor can no longer sense or receive the reflected light. When the cannon body moves from the second moving position to the first moving position, the infrared sensor senses or receives the reflected light again. Therefore, the time spent by the cannon body moving from the first moving position to the second moving position and then returning to the first moving position during the reset process can be automatically calculated. Regardless of whether the cannon body fires once or multiple times, the infrared sensor can keep track of the reset time of the cannon body.

[0020] On the other hand, the infrared sensor is mounted on the cradle via an adjuster, and the adjuster has a first adjustment component, a second adjustment component, and a third adjustment component. In a first direction, the first adjustment component and the second adjustment component are movablely engaged; in a second direction, the second adjustment component and the third adjustment component are movablely engaged, thereby improving the flexibility of the infrared sensor installation inside the artillery and enabling the recoil timing device of the artillery to be adapted to the internal structure of different artillery pieces.

[0027] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0028] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0029] Unless otherwise specified or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0030] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0031] This utility model proposes a recoil timing device for artillery, such as Figures 1 to 2As shown, the device includes a reflective film 1, an infrared sensor 2, an adjuster 3, and a cradle 200. A gun body 100 is disposed on one side of the cradle 200. The reflective film 1 is mounted on the gun body 100. The infrared sensor 2 is mounted on the first end of the adjuster 3, and the second end of the adjuster 3 is mounted on the cradle 200. The emitting end of the infrared sensor 2 faces the reflective film 1. The gun body 100 has at least a first movable position. In the first movable position, the infrared sensor 2 emits light to the reflective film 1 and receives the reflected light from the reflective film 1. The adjuster 3 includes a first adjusting component 31, a second adjusting component 32, and a third adjusting component 33. The infrared sensor 2 is mounted on the first adjusting component 31. In a first direction, the first adjusting component 31 and the second adjusting component 32 are movably coupled. In a second direction, the second adjusting component 32 and the third adjusting component 33 are movably coupled. The third adjusting component 33 is mounted on the cradle 200.

[0032] Specifically, when the cannon is fired, the cannon body 100 moves backward, giving it a first moving position and a second moving position. In the first moving position, the infrared sensor 2 emits light to the reflective film 1 and receives the reflected light from the reflective film 1. When the cannon body 100 moves to the second moving position, the infrared sensor 2 can no longer sense or receive the reflected light. When the cannon body 100 moves from the second moving position to the first moving position, the infrared sensor 2 senses or receives the reflected light again. Therefore, the time taken for the cannon body 100 to move from the first moving position to the second moving position and then back to the first moving position can be automatically calculated. Regardless of whether the cannon body 100 fires once or multiple times, the infrared sensor 2 can keep track of the reset time of the cannon body 100.

[0033] Furthermore, the infrared sensor 2 is mounted on the cradle 200 via the adjuster 3, and the adjuster 3 has a first adjusting component 31, a second adjusting component 32, and a third adjusting component 33. In a first direction, the first adjusting component 31 and the second adjusting component 32 are movablely engaged; in a second direction, the second adjusting component 32 and the third adjusting component 33 are movablely engaged, thereby improving the flexibility of the infrared sensor 2 in the installation inside the artillery and enabling the recoil timing device of the artillery to be adapted to the internal structure of different artillery pieces.

[0034] Preferably, the first adjustment component 31 includes a first support member 310, a first fastener 313, and a second support member 318. The first support member 310 is bent, and the infrared sensor 2 is installed at the first end of the first support member 310. The second end of the first support member 310 has a plurality of first adjustment holes 314, which are distributed in a first direction. The second support member 318 has a first through hole corresponding to any one of the first adjustment holes 314. The first through hole and the first adjustment hole 314 are both through which the first fastener 313 passes. The first support member 310 is fixed to the second support member 318 by the first fastener 313.

[0035] Specifically, the first support member 310 is used to support the infrared sensor 2. The first support member 310 has multiple first adjustment holes 314. The second support member 318 has a first through hole corresponding to any one of the first adjustment holes 314. The first through hole and the first adjustment hole 314 are both for the first fastener 313 to pass through, so that the first support member 310 is fixed on the second support member 318 by the first fastener 313, thereby improving the stability of the first adjustment assembly 31 of the infrared sensor 2. The multiple first adjustment holes 314 can adjust the position of the first support member 310 in the first direction, thereby flexibly adjusting the installation position of the infrared sensor 2.

[0036] Preferably, the second support member 318 includes a first clamping plate 315, a second clamping plate 316, and a through hole formed on the first clamping plate 315 and the second clamping plate 316. The first clamping plate 315 and the first clamping plate 316 are fixedly connected at their first ends, and a first groove is formed between the second ends of the first clamping plate 315 and the second clamping plate 316. The first support member 310 is at least partially located in the first groove and abuts against the first clamping plate 315 and the second clamping plate 316. Specifically, the first groove is formed between the first clamping plate 315 and the second clamping plate 316 to hold the first support member 310, so that the upper and lower ends of the first support member 310 abut against the first clamping plate 315 and the second clamping plate 316 respectively, further improving the stability of the first support member 310 on the second support member 318.

[0037] Preferably, the first support member 310 includes a first support plate 311, a second support plate 312, and a second fastener 317. The first support plate 311 and the second support plate 312 are an integral structure and are vertically arranged. The infrared sensor 2 is fixed to the first support plate 311 by the second fastener 317. A plurality of first adjustment holes 314 are formed on the second support plate 312. Specifically, the first support plate 311 is used to support the infrared sensor 2. The integral structure of the first support plate 311 and the second support plate 312 improves the structural strength of the first support member 310. The vertical arrangement of the first support plate 311 and the second support plate 312 makes the installation position of the infrared sensor 2 more flexible.

[0038] Preferably, each of the first adjustment holes 314 is an oblong hole, and the length of the first adjustment hole 314 is greater than the outer diameter of the first fastener 313. Specifically, the first adjustment hole 314 is an oblong hole, and its length is greater than the outer diameter of the first fastener 313, which facilitates the adjustment of the second support plate 312 in the length direction of the first slot and improves the flexibility of the second support plate 312.

[0039] Preferably, the second adjusting assembly 32 includes a support column 321, a first adjusting rod 322, and a third fastener 323. The support column 321 includes two adjusting blocks 3211, with a second slot 324 between the two adjusting blocks 3211. The length of the second slot 324 is greater than the width of the second support member 318. The second support member 318 is installed in the second slot 324 and slides in a second direction with the second slot 324. The third fastener 323 is installed on either adjusting block 3211 and is used to adjust the size of the second slot 324. Specifically, the two adjusting blocks 3211 are used to adjust the size of the second slot 324, and the second slot 324 is used to accommodate the second support member 318, allowing the second support member 318 to slide in a sliding engagement with it within the second slot 324. The third fastener 323 is used to adjust the size of the second slot 324, improving the stability of the second support member 318 on the support column 321.

[0040] Preferably, each adjusting block 3211 has a through slot, and the openings of the through slots of two adjusting blocks 3211 correspond to each other, forming a second through hole located on the second slot 324. The second through hole allows the first end of the first adjusting rod 322 to pass through, and the second end of the first adjusting rod 322 is fixedly connected to the second support member 318. Specifically, this through slot opening is used to accommodate the first adjusting rod 322 with a larger outer diameter, so that the support column 321 supports the first adjusting rod 322. At the same time, the sliding fit between the first adjusting rod 322 and the through slot opening also facilitates the adjustment of the infrared sensor 2 in the second direction.

[0041] Preferably, the third adjusting assembly 33 includes a second adjusting rod 331, a first bolt 332, and a second bolt 333. A support column 321 is sleeved on the second adjusting rod 331 and slidably engaged with it. The first bolt 332 and the second bolt 333 are both threadedly connected to the second adjusting rod 331, and the support column 321 is located between the first bolt 332 and the second bolt 333. Specifically, by sleeved on the second adjusting rod 331, the second adjusting rod 331 supports the support column 321, and the support column 321 slidably engages with the second adjusting rod 331, further adjusting the position of the support column 321 in a first direction. Moreover, by positioning the support column 321 between the first bolt 332 and the second bolt 333, and by threading the first bolt 332 and the second bolt 333 to the second adjusting rod 331, the position of the support column 321 can be easily restricted after adjustment.

[0042] Preferably, the third adjustment assembly 33 further includes a mounting block 336, a third support plate 334, and a fourth fastener 335. The second adjustment rod 331 is mounted on the third support plate 334, and the mounting block 336 is mounted on the cradle 200. The third support plate 334 has a second adjustment hole. One end of the fourth fastener 335 passes through the second adjustment hole and is threadedly connected to the mounting block 336. The other end of the fourth fastener 335 abuts against the third support plate 334. Specifically, the third support plate 334 has a second adjustment hole, and one end of the fourth fastener 335 passes through the second adjustment hole. The third support plate 334 can be moved to a preset position on the fourth fastener 335, and then the fourth fastener 335 is fixed to the mounting block 336, thereby realizing the adjustment of the position of the infrared sensor 2 in a third direction.

[0043] Preferably, the mounting block 336 is at least partially made of a magnetic material. Specifically, the cradle 200 can be made of magnetic metal, and the magnetic mounting block 336 can be magnetically connected to the cradle 200, further improving the position of the mounting block 336 on the cradle 200 and increasing the installation flexibility of the infrared sensor 2.
