Abstract

The invention discloses a central penetrating parachute cabin and a parachute system, which comprise a parachute cabin body, a cabin cover and a guide sleeve, wherein the cabin cover is detachably arranged at the top of the parachute cabin body, through holes are formed in the bottom of the parachute cabin body and in corresponding positions of the cabin cover, the guide sleeve is fixedly arranged in the parachute cabin body, and two ends of the guide sleeve are respectively communicated with the through holes in the bottom of the parachute cabin body and on the cabin cover. When the front end part and the rear end part of the parachute system are required to be connected through the middle connecting piece, the middle connecting piece can respectively penetrate through the guide sleeve and be respectively connected with the parts positioned at the front end and the rear end of the parachute system, and the limitation that the peripheral circumferential space of the parachute system can only be used when the connection of the front end part and the rear end part of the parachute system is realized is overcome, so that the problem that the reliable connection of the middle connecting piece cannot be ensured due to the fact that the middle connecting piece is positioned in the peripheral space and exposed to high-speed air flow can be avoided.

Description

Parachute cabin penetrating through center and parachute system Technical Field The invention relates to the technical field of parachutes, in particular to a central penetrating parachute cabin and a parachute system. Background The parachute is generally composed of a parachute, a parachute bag, a parachute cabin and other parts, and the parachute is arranged in the parachute bag and the parachute cabin to form an independent fully-closed structure. In conventional applications, the parachute system for objects is usually located at the end of a load (i.e. the load is located at the front end of the parachute system), and as disclosed in patent application number 201620864606.4, an unmanned aerial vehicle parachute cabin and an unmanned aerial vehicle are disclosed, wherein the unmanned aerial vehicle parachute cabin comprises a barrel, an upper cabin cover arranged at the upper bottom of the barrel, and a supporting plate arranged in the barrel, wherein a parachute is arranged between the upper cabin cover and the supporting plate. As technology advances, there are situations in which components (e.g., engines) are also present at the back end of the parachute system in some applications. In such applications, the connection of the front and rear end parts of the parachute system can only use the peripheral circumferential space of the parachute system, but cannot utilize the central part of the parachute system, so that the reliable connection cannot be ensured for fragile parts such as cables, etc. due to exposure to high-speed airflow in the peripheral space. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a central penetrating parachute cabin and a parachute system, which solve the technical problems that the connection of front and rear end parts of the parachute system in the prior art can only use the peripheral circumferential space of the parachute system and the central part of the parachute system can not be utilized, so that the fragile parts such as cables and the like can not be ensured to be reliably connected due to exposure to high-speed airflow in the peripheral space. In order to achieve the technical purpose, the technical scheme of the invention provides a central penetrating umbrella cabin which comprises an umbrella cabin body, a cabin cover and a guide sleeve, wherein the cabin cover is detachably arranged at the top of the umbrella cabin body, through holes are formed in the bottom of the umbrella cabin body and the corresponding positions of the cabin cover, the guide sleeve is fixedly arranged in the umbrella cabin body, and two ends of the guide sleeve are respectively communicated with the through holes in the bottom of the umbrella cabin body and the through holes in the cabin cover. Furthermore, the central penetrating parachute cabin further comprises a plurality of parachute connection plates, and the parachute connection plates are fixedly arranged on the upper surface of the bottom of the parachute cabin body. Further, the number of the umbrella connecting plates is set to be a plurality, and the plurality of umbrella connecting plates are distributed at the bottom of the umbrella cabin along the circumferential direction. The technical scheme of the invention also provides a parachute system, which comprises the central penetrating parachute cabin and a parachute, wherein the parachute comprises a canopy and a plurality of parachute ropes which are fixedly connected, the canopy and the parachute ropes are both contained in the parachute cabin, and the distal ends of the parachute ropes are fixedly connected with the bottom of the parachute cabin body.
