Description

Technical Field

[0001] The utility model relates to the technical field of recoil mechanisms, in particular to a device for checking the liquid level of a cannon recoil mechanism. Background Art

[0002] The function of the recoil mechanism is to consume and absorb the recoil kinetic energy during recoil, control the recoil speed during recoil, and ensure the stability of the recoil part during recoil and recoil. The recoil mechanism is filled with recoil fluid. When there is less fluid, it may cause equipment failures such as too long recoil distance and too violent recoil of the gun. When there is more fluid, it may endanger the safety of gun shooting. When checking the fluid level of the recoil mechanism, hit the gun body to a rough level, unscrew the inspection hole plug at the upper end of the recoil mechanism, and use the naked eye to check whether the liquid in the recoil mechanism is flush with the inspection plane at the lower end of the inspection hole. If it is flush, the liquid level meets the standard. Otherwise, there is a lack of recoil fluid and it needs to be manually filled. When checking the fluid level of the recoil mechanism, it is necessary to remove the inspection hole plug for manual inspection, especially for some guns where the recoil mechanism is in the fighting room. The upper space of the recoil mechanism inspection hole is limited, and the fluid level inspection is very inconvenient. Before the recoil mechanism is installed on the artillery, it has been subjected to a pressure test and is generally not prone to leakage. However, considering the safety of the artillery during firing, the technicians must check the fluid level of the recoil mechanism one by one before actual firing. The method of unscrewing the screw plug on the recoil mechanism for inspection is not only time-consuming and labor-intensive, but also prone to failure of the copper gasket under the screw plug due to repeated removal of the inspection hole screw plug, resulting in additional equipment consumption, or liquid spraying during shooting due to the screw plug not being screwed into place, etc. Therefore, we propose a gun recoil mechanism fluid level inspection device to solve the above problems. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a device for checking the fluid volume of a gun recoil mechanism.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for inspecting the fluid level of a gun recoil mechanism comprises a recoil mechanism body, a threaded inspection hole is provided on the outer wall of the recoil mechanism body, a screw is threadedly connected to the inner wall of the threaded inspection hole, a through hole is provided on the outer wall of the screw, an induction probe is fixedly connected to the inner wall of the through hole, a nut is fixedly connected to the top of the screw, a sealing gasket is fixedly connected to the inner wall of the nut, a copper gasket is provided on the sliding sleeve of the outer wall of the screw, and a detection mechanism is installed on the nut.

[0006] Preferably, the detection mechanism includes an acoustic-optical signal generator, the inner wall of the nut is fixedly connected to the outer wall of the acoustic-optical signal generator, the outer wall of the acoustic-optical signal generator is fixedly connected with a wire, and the acoustic-optical generator is arranged to be used in conjunction with the induction probe to detect the amount of the receding liquid.

[0007] Preferably, the outer wall of the copper gasket is pressed against the outer wall of the recoil machine body, and the sealing performance of the screw is improved by providing the copper gasket.

[0008] Preferably, one end of the wire is electrically connected to a power source, the acousto-optic signal generator is electrically connected to the inductive probe, and the acousto-optic signal generator and the inductive probe are powered by the power source.

[0009] Preferably, a recoil liquid is provided inside the recoil machine body.

[0010] Preferably, the inner wall of the parking machine body is slidably connected to a piston, and the outer wall of the piston is fixedly connected to a piston rod.

The device has a fast detection speed and can display the detection results by simply connecting to the power supply. It solves the cumbersome steps of removing the screw plugs in the threaded inspection holes of each gun during inspection and relying on manual inspection with the naked eye. Now, only the recoil machine body with abnormal detection needs to be processed, and it also avoids repeated disassembly and assembly that affects the sealing performance of the inspection screw plug.

It is suitable for large-scale batch production and application. While improving the integrity rate of equipment parts, it helps to improve the maintenance and support efficiency.

[0022] The nut 4 is equipped with a detection mechanism, which includes an acoustic and optical signal generator 8. The acoustic and optical signal generator 8 receives the signal transmitted by the sensing probe 6. When the internal sensing device detects that a specific state occurs, it will transmit the signal to the control circuit to control the operation of the sound generator and the light source generator. The inner wall of the nut 4 is fixedly connected to the outer wall of the acoustic and optical signal generator 8.

When there is recoil fluid at the sensing probe 6, an electrical signal is given, and the green light of the sound and light signal generator 8 flashes; when there is no recoil fluid at the sensing probe 6, the sound and light signal generator 8 gives an alarm sound and the red light flashes; technical support personnel can perform corresponding operations according to the signal given by the device; when the artillery recoils and recoils, the sealing gasket 3 is used to prevent the recoil fluid in the recoil machine body 9 from leaking from the sensing probe 6; since the device is installed on the upper part of the recoil machine, the power supply 2 and the wire 1 are only used during inspection, and are usually kept by the artillery use team to prevent the vibration of the artillery shooting from damaging the equipment.
