Description

Technical Field

[0001] The present invention relates to the technical field of hot air balloons, in particular to a high-safety hot air balloon. Background Art

[0002] Hot air ballooning has become a popular aeronautical sport, and is also commonly used for aerial photography and tourism. A hot air balloon uses hot air as its buoyancy. Its main components are a balloon, a cylinder, a burner, and a basket. The burner heats the air inside the balloon, reducing its density and causing it to rise. To lift off from the ground, the burner is ignited to heat the cool air inside. Once airborne, the burner's flame is controlled to control the balloon's ascent or descent.

[0003] When operating a hot air balloon, the balloon's maximum continuous operating temperature must not exceed 120°C. Temperatures between 120°C and 130°C cannot exceed 5 minutes within 2 hours. The balloon's maximum temperature limit is 130°C. If it exceeds 130°C, the fabric strength must be tested. Traditionally, hot air balloon balloon temperature measurements were performed using a balloon thermometer, which connected to a probe via a standard 30-meter cable. This made installation cumbersome and prone to entanglement with other balloon cables, potentially causing safety accidents. Consequently, many pilots failed to install balloon thermometers during flight, relying solely on experience to control the balloon's maximum continuous operating temperature, which compromised flight safety. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above technical deficiencies and propose a highly safe hot air balloon to solve the technical problem in the prior art that during hot air balloon flight, the pilot controls the maximum continuous operating temperature of the balloon based solely on experience, which affects flight safety.

[0005] To achieve the above technical objectives, the technical solution of the present invention provides a highly safe hot air balloon, comprising a balloon, a temperature flag mechanism, and a burner. The balloon has a balloon cavity formed therein. The burner is disposed below the balloon and is used to heat the air within the balloon cavity. The temperature flag mechanism comprises:

[0006] A mounting plate, fixedly disposed in the balloon cavity at a position close to the inner surface of the balloon;

[0007] Two thermal clips are fixedly arranged on both sides of the mounting plate, and a clamping opening is formed between the bottoms of the two thermal clips;

[0008] A temperature flag is provided in the clamping opening;

[0009] When the temperature in the balloon cavity reaches the maximum continuous operating temperature of the balloon, the jaws open and release the temperature flag to remind the pilot to shut down the burner.

[0010] Furthermore, the thermally sensitive clip is a thermal bimetallic strip, which includes an active layer located at the inner layer and a passive layer located at the outer layer;

[0011] When the temperature changes, the deformation of the active layer is greater than that of the passive layer, causing the thermal bimetallic strip to bend toward one side of the passive layer, thereby causing the thermal clip to open.

[0012] Furthermore, the temperature flag mechanism further includes a hanging member, and the heat-sensitive clip further includes a hanging pin fixed in its opening, and the temperature flag is hung on the hanging pin through the hanging member.

[0013] Furthermore, the hanging piece is an "8"-shaped ring.

[0014] Furthermore, the high-safety hot air balloon also includes a connecting rope fixedly connected to the inner wall of the balloon, and the distal end of the connecting rope is fixedly connected to the suspension member.

[0015] Furthermore, the high-safety hot air balloon also includes a bell fixedly arranged on the connecting rope.

[0016] Furthermore, both the mounting plate and the thermal clip are provided with mounting holes, bolts are installed in the mounting holes, and the thermal clip is fixed to the mounting plate by the bolts.

[0017] Furthermore, at least two mounting holes are provided on the mounting plate and the thermal clip, and bolts are installed in the mounting holes.

[0018] Furthermore, it also includes a washer, which is sleeved between the thermal clip and the mounting plate and on the outer surface of the bolt.

[0019] Furthermore, the gasket is a heat-insulating gasket.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By adding the temperature flag mechanism in the balloon cavity, when the temperature in the balloon cavity reaches the maximum continuous operating temperature of the balloon, the clamp opens and releases the temperature flag to alert the pilot. After the pilot notices the falling temperature flag, he turns off the burner and lands the hot air balloon, avoiding damage to the balloon due to excessive temperature, thereby improving the safety of hot air balloon use.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The present invention provides a high-safety hot air balloon, the structure of which is as follows: Figure 1 As shown, it includes a balloon 1, a temperature flag mechanism 2 and a burner (not shown in the figure), wherein a balloon cavity 10 is formed inside the balloon 1, and the burner is arranged below the balloon 1 for heating the air inside the balloon cavity 10; the temperature flag mechanism 2 includes a mounting plate 21, two heat-sensitive clips 22 and a temperature flag 23, wherein the mounting plate 21 is fixedly arranged in the balloon cavity 10 at a position close to the inner surface of the balloon 1; the two heat-sensitive clips 22 are respectively fixedly arranged on both sides of the mounting plate 21, and a clamp is formed between the bottoms of the two heat-sensitive clips 22; the temperature flag 23 is clamped in the clamp;

[0027] When the temperature in the balloon cavity 10 reaches the maximum continuous operating temperature of the balloon 1 , the jaws open and release the temperature flag 23 to remind the pilot to turn off the burner.

[0028] It can be understood that by adding the temperature flag mechanism 2 in the balloon cavity 10, when the temperature in the balloon cavity 10 reaches the maximum continuous operating temperature of the balloon 1, the clamp opens and releases the temperature flag 23 to remind the pilot. After the pilot notices the falling temperature flag 23, he turns off the burner and lands the hot air balloon, avoiding damage to the balloon 1 due to excessive temperature, thereby improving the safety of the hot air balloon.

[0029] like Figure 2 FIG. 2 is a side view of the thermal clip in this embodiment. As a preferred embodiment, the thermal clip 22 is a thermal bimetallic strip, which includes an active layer 221 located at the inner layer and a passive layer 222 located at the outer layer.

[0030] When the temperature changes, the deformation of the active layer 221 is greater than that of the passive layer 222 , causing the thermal bimetallic strip to bend toward one side of the passive layer 222 , thereby causing the thermal clip 22 to open.

[0031] It can be understood that by selecting the thermal bimetallic strip as the thermal clip 22 and utilizing the different thermal expansion coefficients of the active layer 221 and the passive layer 222, when the temperature in the balloon cavity 10 reaches the maximum continuous operating temperature of the balloon 1, the thermal bimetallic strip bends toward one side of the passive layer 222, thereby causing the thermal clip 22 to open to release the temperature flag 23.

[0032] As a preferred embodiment, the temperature flag mechanism 2 further includes a hanging member 24, and the heat-sensitive clip 22 further includes a hanging pin 223 fixed in its opening. Figure 3 The top of the temperature flag 23 is fixedly connected with a hanging member 24 , and the temperature flag 23 is hung on the hanging pin 223 through the hanging member 24 .

[0033] As a preferred embodiment, the hanging member 24 is an "8" ring.

[0034] It should be noted that the selection of the hanging member 24 as an "8" ring is only a preferred implementation in this embodiment. In other embodiments, the hanging member 24 can also be other types, such as a hook.

[0035] As a preferred embodiment, the high-safety hot air balloon further includes a connecting rope 3 fixedly connected to the inner wall of the balloon 1 , and the distal end of the connecting rope 3 is fixedly connected to the suspension member 24 .

[0036] It can be understood that when the thermal clip 22 is opened, the hanging part 24 and the temperature flag 23 fall downward. By connecting the connecting rope 3 between the hanging part 24 and the balloon 1, the hanging part 24 and the temperature flag 23 can be avoided from being lost, so that they can be reused.

[0037] As a preferred embodiment, the high-safety hot air balloon further includes a bell 4 fixedly arranged on the connecting rope 3, which can further remind the pilot to turn off the burner.

[0038] As a preferred embodiment, mounting holes are provided on the mounting plate 21 and the thermal clip 22 . Bolts 5 are installed in the mounting holes, and the thermal clip 22 is fixed to the mounting plate 21 by the bolts 5 .

[0039] It is understandable that fixing the thermal clip 22 on the mounting plate 21 by the bolts 5 can prevent the thermal clip 22 from falling, thereby enabling the thermal clip 22 to be reused.

[0040] As a preferred embodiment, at least two mounting holes are provided on the mounting plate 21 and the thermal clip 22 , and bolts 5 are installed in the mounting holes.

[0041] It is understandable that the thermal clips 22 are fixed to the mounting plate 21 by at least two bolts 5 , which can prevent the thermal clips 22 from rotating relative to the mounting plate 21 and thus prevent the clamping opening from being formed between the two thermal clips 22 .

[0042] As a preferred embodiment, a washer is further included. The washer is sleeved between the thermal clip 22 and the mounting plate 21 and on the outer surface of the bolt 5 .

[0043] As a preferred embodiment, the gasket is a thermal insulation gasket.

[0044] It is understood that the gasket can prevent the thermal clip 22 from being crushed when it is installed; the heat-insulating gasket can prevent the heat of the thermal clip 22 from being transferred to the mounting plate 21 to make the thermal clip 22 ineffective. Figure 1-Figure 3 The working principle of this solution is described in detail:

[0045] When the hot air balloon is flying in the air, when the temperature inside the balloon cavity 10 reaches the maximum continuous operating temperature of the balloon 1, due to the different thermal expansion coefficients of the active layer 221 and the passive layer 222, the thermal bimetallic strip bends toward one side of the passive layer 222, thereby causing the clamp to open and release the suspension 24 and the temperature flag 23, which is used to remind the pilot that the temperature inside the balloon cavity 10 has reached the maximum continuous operating temperature of the balloon 1. At this time, the pilot must immediately turn off the burner to land the hot air balloon, and inspect or replace the balloon 1 after landing.

[0046] The high-safety hot air balloon provided by the present invention has the following beneficial effects:

[0047] (1) By adding the temperature flag mechanism 2 in the balloon cavity 10, when the temperature in the balloon cavity 10 reaches the maximum continuous operating temperature of the balloon 1, the clamp opens and releases the temperature flag 23 to alert the pilot. After the pilot notices the falling temperature flag 23, he turns off the burner and lands the hot air balloon, thus preventing the balloon 1 from being damaged due to excessive temperature, thereby improving the safety of the hot air balloon.

[0048] (2) By connecting the connecting rope 3 between the hanging member 24 and the balloon 1, the hanging member 24 and the temperature flag 23 can be prevented from being lost, so that they can be reused.

[0049] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
