Description

Technical Field

[0001] The utility model relates to the technical field of aircraft, in particular to a novel pitot tube provided with heat dissipation grooves. Background Technique

[0002] A pitot tube is a device used to measure flight speed and other atmospheric data. Its main function is to sense the total pressure (also known as the stagnation pressure) and static pressure of the air flow, and transmit the measured pressure data to devices such as an atmospheric data computer and flight instruments.

[0003] In the prior art, it is very easy to make the drilled holes in the part for installing the metal pitot tube body irregular, not a perfect circle. It is inconvenient to apply glue in the drilled hole part and it cannot be fixed firmly. After inserting the metal pitot tube body into the drilled hole part, it is easy to accidentally touch it when the unmanned aerial vehicle is stationary on the ground, and the position where the metal pitot tube body is fixedly connected is cracked, which results in a relatively high after-sales rate. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel pitot tube provided with heat dissipation grooves to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, a novel pitot tube provided with heat dissipation grooves provided by the utility model includes a fuselage, an arc plate is arranged on the fuselage, a heat dissipation groove body is opened on the arc plate, and a pitot tube body is installed on the arc plate.

[0006] Further, a plurality of holes are opened on the fuselage. The inner wall of one of them is provided with a first trapezoidal block, the inner wall of another one is provided with a second trapezoidal block, and the remaining one is provided with a third trapezoidal block. Telescopic rods and return springs are arranged between the first trapezoidal block, the second trapezoidal block, the third trapezoidal block and the arc plate. The return spring is arranged on the outer wall of the telescopic rod, and the fuselage is provided with insertion holes adapted to the first trapezoidal block, the second trapezoidal block and the third trapezoidal block.

[0007] Further, a third pull rope is installed on the first trapezoidal block. The other end of the third pull rope passes through the arc plate and is installed with a circular ring. A placement groove is opened on the arc plate, and the circular ring is arranged inside the placement groove.

[0008] Further, a first pulley is rotatably connected inside the arc plate. A second pull rope is installed on one side of the third trapezoidal block. The other end of the second pull rope passes through the telescopic rod and is installed with a finger ring. The second pull rope abuts against the outer wall of the first pulley.

[0009] Further, a first pulling rope is installed on one side of the second trapezoidal block. The first pulling rope passes through the other end of the telescopic rod and is installed with a pulling ring. A second pulley is rotatably connected to the inner wall of the arc-shaped plate, and the first pulling rope is lapped on the second pulley.

[0010] Further, an installation groove is formed on the arc-shaped plate, and both the pulling ring and the finger ring are arranged inside the installation groove.

[0011] Further, sealing covers are screwed to both the installation groove and the placement groove.

[0012] Further, the pulling ring, the finger ring, and the circular ring are all made of rubber.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the arc-shaped plate integrates an airspeed tube and a heat dissipation groove. After the template is perforated, the arc-shaped plate is fixed to the fuselage with Kraft silicone, which shortens the installation time, improves the aesthetics and firmness. The heat dissipation groove enhances the battery heat dissipation, ensures stability, reduces the risk of accidental touch, and reduces the after-sales rate.

[0015] 2. In the present utility model, when the staff installs the arc-shaped plate on the fuselage, the inclined surfaces of multiple trapezoidal blocks abut against the fuselage. After applying pressure, the return spring is compressed, and the trapezoidal blocks slip on the fuselage and smoothly enter the insertion holes. Silicone is used at the pores to keep a distance from the trapezoidal blocks, enhancing the fixing stability. When accidentally touching the airspeed tube, the arc-shaped plate and its structural stability are better. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0024] Refer to Figure 1 As shown in the figure, a new type of airspeed tube provided with a heat dissipation groove includes a fuselage 1, an arc plate 2 is arranged on the fuselage 1, a heat dissipation groove body 3 is opened on the arc plate 2, and an airspeed tube body 4 is fixedly installed on the arc plate 2.

[0025] The arc plate 2 in which the airspeed tube body 4 and the heat dissipation groove body 3 are integrated. The fuselage 1 is perforated with a template, and finally, Kraft 704 silicone is used to bond the arc plate 2 to the fuselage 1. By improving the fixing method, the installation time is greatly shortened, and the unsightly and insecure problems caused by perforating and gluing are better avoided, and the assembly time is shortened. Since the battery compartment of the fuselage 1 is a closed space, in the case of high temperature, the heat dissipation groove body 3 can effectively help the battery dissipate heat and ensure the stability of the battery. This fixing method reduces the risk that customers accidentally touch the airspeed tube body 4 when the drone is stationary on the ground, and reduces the after-sales rate.

[0026] Refer to Figures 2 - 3 As shown in the figure, a plurality of 19 are opened on the fuselage 1. The inner wall of one of the 19 is provided with a first trapezoidal block 5, the inner wall of another one of the 19 is provided with a second trapezoidal block 6, and the remaining one of the 19 is provided with a third trapezoidal block 7. Telescopic rods 8 and return springs 9 are arranged between the first trapezoidal block 5, the second trapezoidal block 6, the third trapezoidal block 7 and the arc plate 2. The return spring 9 is arranged on the outer wall of the telescopic rod 8, and the fuselage 1 is provided with insertion holes adapted to the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7.

[0027] The staff installs the arc-shaped plate 2 on the fuselage 1. The inclined surfaces of the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 are all in contact with the fuselage 1. The staff applies a pressure towards the fuselage 1 on the arc-shaped plate 2, and the return spring 9 is compressed under force. The inclined surfaces of the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 will slip on the fuselage 1, and the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 can smoothly enter the interior of the jack. Silicone is used in the gap between the fuselage 1 and the arc-shaped plate 2, and this gap position is kept at a certain distance from the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7, so that the fixation between the fuselage 1 and the arc-shaped plate 2 is more stable. When accidentally touching the pitot tube body 4 by mistake, the stability of the arc-shaped plate 2 including structures such as the pitot tube body 4 will be better.

[0028] Refer to Figure 2 and Figure 5 A third pull rope 16 is fixedly installed on the first trapezoidal block 5. The third pull rope 16 passes through the other end of the arc-shaped plate 2 and is fixedly installed with a circular ring 17. A placement groove is formed on the arc-shaped plate 2, and the circular ring 17 is arranged inside the placement groove.

[0029] When the user pulls the circular ring 17, the circular ring 17 pulls the first trapezoidal block 5 in the direction of the circular ring 17 through the third pull rope 16, so that the first trapezoidal block 5 disengages from the jack on the fuselage 1.

[0030] Refer to Figures 2 - 3 A first pulley 12 is rotatably connected inside the arc-shaped plate 2. A second pull rope 11 is fixedly installed on one side of the third trapezoidal block 7. The second pull rope 11 passes through the other end of the telescopic rod 8 and is fixedly installed with a finger ring 15. The second pull rope 11 abuts against the outer wall of the first pulley 12.

[0031] The mutual cooperation of the second pull rope 11 and the first pulley 12 can prevent the second pull rope 11 from touching the inner wall edges and corners of the arc-shaped plate 2, thereby reducing the friction with the inner wall edges and corners of the arc-shaped plate 2 when pulling the second pull rope 11. At the same time, it can also change the force direction of the second pull rope 11, and it will be more labor-saving when pulling the second pull rope 11.

[0032] Refer to Figure 3 A first pull rope 10 is fixedly installed on one side of the second trapezoidal block 6. The first pull rope 10 passes through the other end of the telescopic rod 8 and is fixedly installed with a pull ring 14. A second pulley 13 is rotatably connected to the inner wall of the arc-shaped plate 2, and the first pull rope 10 is lapped on the second pulley 13.

[0033] The first drawstring 10 connecting the second trapezoidal block 6 passes through the arc-shaped plate 2 and then bypasses the bottom of the second pulley 13 above the second pulley 13. Guided by the second pulley 13, the cooperation between the second pulley 13 and the first drawstring 10 can achieve the transmission and conversion of the pulling force, enabling the second trapezoidal block 6 to be pulled more easily. Under the guidance of the second pulley 13, the first drawstring 10 can move along a specific path, improving work efficiency.

[0034] Refer to Figure 4 , an installation groove 18 is provided on the arc-shaped plate 2, and both the pull ring 14 and the finger ring 15 are arranged inside the installation groove 18.

[0035] Placing the pull ring 14 and the finger ring 15 inside the installation groove 18, combined with the mutual cooperation of the sealing covers, can make the appearance of the entire arc-shaped plate 2 more tidy and unified, without looking messy due to the protrusion of external accessories. The pull ring 14 and the finger ring 15 can disengage the second trapezoidal block 6 and the third trapezoidal block 7 from the jack on the fuselage 1, facilitating the detachment of the arc-shaped plate 2 from the fuselage 1.

[0036] Refer to Figures 4 - 5 , sealing covers are threadedly connected to both the installation groove 18 and the placement groove.

[0037] Threaded connection can provide a strong fastening force, enabling the sealing covers to be firmly fixed on the installation groove 18 and the placement groove. This fastening property not only ensures the reliability of the seal but also prevents the sealing covers from loosening or falling off under external forces such as vibration or impact. The sealing covers can better protect the parts inside the installation groove 18 and the placement groove.

[0038] Refer to Figures 4 - 5 , the pull ring 14, the finger ring 15, and the circular ring 17 are all made of rubber.

[0039] The rubber-made pull ring 14, finger ring 15, and circular ring 17 can increase the friction with the hand, prevent slipping, and at the same time provide a better grip, reducing the risk of accidental detachment.

[0040] Working principle: The arc-shaped plate 2 with the airspeed tube body 4 and the heat dissipation groove body 3 integrated. Use a template to perforate the fuselage 1, and finally use Kraft 704 silicone to bond the arc-shaped plate 2 to the fuselage 1. By improving the fixing method, the installation time is significantly shortened, better avoiding the unsightliness and instability caused by perforating and gluing for fixing, shortening the assembly time. Since the battery compartment of the fuselage 1 is a closed space, in high-temperature conditions, the heat dissipation groove body 3 can effectively help the battery dissipate heat and ensure the stability of the battery. This fixing method reduces the risk that customers accidentally touch the airspeed tube body 4 when the drone is stationary on the ground, reducing the after-sales rate.

[0041] The staff installs the arc-shaped plate 2 on the fuselage 1. The inclined surfaces of the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 are all in contact with the fuselage 1. The staff applies a pressure towards the fuselage 1 on the arc-shaped plate 2. The return spring 9 is compressed under force. The inclined surfaces of the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 will slip against the fuselage 1, and the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7 can smoothly enter the inside of the jack. Silicone is used in the gap between the fuselage 1 and the arc-shaped plate 2. This gap position is kept at a certain distance from the first trapezoidal block 5, the second trapezoidal block 6, and the third trapezoidal block 7, so that the fixation between the fuselage 1 and the arc-shaped plate 2 is more stable. When the pitot tube body 4 is accidentally touched, the stability of the arc-shaped plate 2 including structures such as the pitot tube body 4 will be better.
