Description

Technical Field

[0001] This utility model relates to the field of gyroscope technology, specifically a dual-axis gyroscope assembly. Background Technology

[0002] A gyroscope is a device that uses the angular momentum of a high-speed rotating body to sense the angular velocity of its housing relative to inertial space around one or two axes orthogonal to its rotation axis. Gyroscopes are also used to detect angular velocity using other principles that perform the same function.

[0003] Gyroscopes are classified into dual-axis and tri-axis gyroscopes. When transporting artillery, gyroscopes are needed to measure the stability of the transport vehicle. However, the heat generated during gyroscope operation can cause aging of internal components, such as changes in resistance over time or abnormal circuit operation. Extreme temperature changes can also cause bubbles to form in liquid components, further affecting the accuracy of attitude measurement. Therefore, a dual-axis gyroscope assembly is proposed.

[0005] In view of the problems existing in the above and / or existing dual-axis gyroscopes, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a dual-axis gyroscope assembly. The gyroscope measures the angular velocity of the artillery relative to inertial space. When the gyroscope is in use, the heat-conducting fins conduct heat out of the gyroscope. The liquid flow in the cold water pipe drives the blower mechanism to work, so that the low-temperature airflow at the cold water pipe blows upward to the heat-conducting fins to dissipate heat and achieve heat dissipation of the gyroscope, thus avoiding the aging of the internal components of the gyroscope from affecting the detection accuracy.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] This invention provides a dual-axis gyroscope assembly. The gyroscope measures the angular velocity of an artillery piece relative to inertial space. During operation, heat-conducting fins conduct heat from within the gyroscope. The flow of liquid in a cooling water pipe drives a blower mechanism, causing a low-temperature airflow to rise and dissipate heat from the heat-conducting fins. This heat dissipation prevents aging of internal components from affecting detection accuracy. (See also...) Figures 1-4 It includes: gyroscope 100, cooling mechanism 200 and blower mechanism 300.

[0030] The gyroscope 100 includes a housing 110 and heat-conducting fins 120 uniformly disposed on the sidewall of the housing 110;

[0031] Among them, the gyroscope 100 adopts a dual-axis gyroscope, and the heat-conducting fins 120 are used to conduct heat out of the gyroscope 100 to achieve heat dissipation of the gyroscope. The gyroscope measures the angular velocity of the artillery relative to the inertial space, and the closed-loop servo control system isolates the angular velocity of the vehicle's motion to achieve the purpose of positioning the artillery in the inertial space.

[0032] The refrigeration mechanism 200 is located outside the housing 110. The refrigeration mechanism 200 includes a cold water tank 210, a cold water pipe 220, a pump 230, and a refrigeration component 240. The side wall of the cold water tank 210 is connected to the cold water pipe 220. The pump 230 is installed on the cold water pipe 220, and the refrigeration component 240 is installed on the cold water tank 210.

[0033] The refrigeration component 240 cools the water in the cold water tank 210, keeping the internal cooling water at a low temperature. The pump 230 draws out the cooling water, causing the water to circulate between the cold water tank 210 and the cold water pipe 220, thereby reducing the temperature around the cold water pipe 220.

[0034] The blower mechanism 300 is evenly arranged on the cold water pipe 220. The blower mechanism 300 includes a first rotating shaft 310, a drive turbine 320, a drive bevel gear 330, a second rotating shaft 340, a driven bevel gear 350, and an impeller 360. The first rotating shaft 310 is rotatably connected inside the cold water pipe 220. The drive turbine 320 is provided at one end of the first rotating shaft 310, and the drive bevel gear 330 is provided at the other end of the first rotating shaft 310. The second rotating shaft 340 is rotatably connected to the top end of the cold water pipe 220. The driven bevel gear 350 that meshes with the drive bevel gear 330 is provided at the lower end of the second rotating shaft 340, and the impeller 360 is provided at the top end of the second rotating shaft 340.

[0035] The blower mechanism 300 is evenly distributed on the cold water pipe 220 and is located between the heat-conducting fins 120. When the liquid flows, the first rotating shaft 310 is driven to rotate by the drive turbine 320. The first rotating shaft 310 drives the drive bevel gear 330 to rotate synchronously. The drive bevel gear 330 meshes and drives the driven bevel gear 350 to rotate. The driven bevel gear 350 drives the impeller 360 to rotate through the second rotating shaft 340. The impeller 360 drives the airflow to flow, so that the airflow blows upward to the heat-conducting fins 120. When the airflow flows, it drives the low-temperature gas around the cold water pipe 220 to flow upward, so that the low-temperature airflow blows to the heat-conducting fins 120.

[0036] Since the ash content will increase when the cooling water is recirculated, in order to achieve a uniform temperature distribution in the cold water tank 210, a mixing mechanism 400 is provided in the inner cavity of the cold water tank 210. The mixing mechanism 400 includes a third rotating shaft 410, a deflector 420 and a mixing blade 430. The third rotating shaft 410 is rotatably connected to the side wall of the inner cavity of the cold water tank 210. The deflector 420 is evenly distributed at one end of the third rotating shaft 410 near the inner wall of the cold water tank 210, and the mixing blade 430 is provided at the other end of the third rotating shaft 410.

[0037] The left and right ends of the cold water pipe 220 are respectively connected to the two ends of the side wall of the cold water tank 210. The deflector 420 is located at the return water port of the cold water pipe 220. The returning coolant flows to the deflector 420, causing the deflector 420 to drive the third rotating shaft 410 to rotate. The third rotating shaft 410 simultaneously drives the mixing blade 430 to rotate, and the mixing blade 430 stirs the cooling water in the cold water tank 210.

[0038] The cooling component 240 uses a semiconductor cooling chip. The cooling end of the semiconductor cooling chip faces the inner cavity of the cold water tank 210 and is in contact with the cooling water to cool it. The heat dissipation end faces the outer side of the cold water tank 210. To prevent the heat dissipated by the cooling component 240 from being transferred to the gyroscope 100, the cooling component 240 can be installed on the right side wall of the cold water tank 210. Figure 2 The installation position of the refrigeration component 240 can be adjusted as needed, with the middle section located on the left side wall.

[0039] The cold water tank 210 has an observation window on its side wall. The observation window is an explosion-proof window, which makes it easy to observe the internal working status.

[0040] In practical use, the gyroscope measures the angular velocity of the artillery relative to inertial space, and the closed-loop servo control system isolates the vehicle's angular velocity to achieve the artillery's positioning in inertial space. Heat-conducting fins 120 are used to dissipate heat from the gyroscope 100, achieving gyroscope cooling. Pump 230 draws out cooling water, causing it to circulate between the cold water tank 210 and the cold water pipe 220, lowering the temperature around the cold water pipe 220. During the flow, the drive turbine 320 drives the first rotating shaft 310 to rotate, which in turn drives the drive bevel gear 330 to rotate. The drive bevel gear 330 engages the belt... The driven bevel gear 350 rotates, and the driven bevel gear 350 drives the impeller 360 to rotate through the second rotating shaft 340. The impeller 360 drives the airflow to flow, so that the airflow blows upward to the heat-guiding fins 120. When the airflow flows, it drives the low-temperature gas around the cold water pipe 220 to flow upward, so that the low-temperature airflow blows to the heat-guiding fins 120, improving the cooling effect. The returning coolant flows to the deflector plate 420, which causes the deflector plate 420 to drive the third rotating shaft 410 to rotate. The third rotating shaft 410 synchronously drives the mixing blades 430 to rotate. The mixing blades 430 agitate the cooling water in the cold water tank 210, so that the temperature of the cooling water in the cold water tank 210 is evenly distributed.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
