Description

Technical Field

[0001] This utility model relates to the field of high-end fire-fighting equipment technology for fire-fighting robots, and in particular to an olive-shaped hose drag-resistant protective sleeve. Background Technology

[0002] Fire hoses are used to deliver large amounts of water or other extinguishing agents (such as foam) to the fire source at a fire scene. When dealing with different fire sources, fire hoses need to be dragged across the ground. In complex ground conditions, wear-resistant protection for the hoses and hose joints is particularly necessary. With the widespread use of firefighting robots, because they cannot match the dexterity of humans, damage to the hoses or hose joints can easily occur during the dragging process, causing delays or disruptions to fire rescue efforts.

[0003] A search revealed that Chinese patent CN215938868U discloses an anti-detachment hose protective sleeve, which includes a sleeve. After the hose and connector are tied together, the notch is opened and the sleeve is snapped onto the hose at the connection with the connector, thus protecting the hose at the connection. Chinese patent CN214860807U discloses a new type of hose protective sleeve, which effectively prevents damage caused by friction between the hose and the ground and internal damage to the hose caused by collision at the connection with the connector through the setting of a first sleeve and a second sleeve.

[0004] Both of the above-mentioned hose protective sleeves focus on protecting the hose joints. Both use a bolt and nut structure for installation, which is not simple or efficient and has certain limitations. Furthermore, the existing protective sleeves are still cylindrical in shape, which is not conducive to robots dragging hoses over obstacles.

[0005] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose an olive-shaped hose drag-resistant protective sleeve to solve the problems of existing protective sleeves being inconvenient to cross obstacles and not simple and efficient in the installation process when protecting hoses or hose joints.

[0007] Based on the above objectives, this utility model provides an olive-shaped hose drag resistance protection sleeve, including a protective shell. The protective shell is open at both ends and has a cavity inside to accommodate the hose or hose connector. The protective shell is oval-shaped, with a larger middle section and smaller ends. The protective shell gradually tapers from the middle section to both sides to form an inclined surface.

[0008] The protective shell is divided into an upper protective shell and a lower protective shell by a transverse section. The edges of the upper and lower protective shells are provided with snap-fit ​​components. Each snap-fit ​​component includes a snap-fit ​​block and a snap-fit ​​groove. The snap-fit ​​block is located at the middle and both ends of the two sides of the upper protective shell, and the snap-fit ​​groove is located at the middle and both ends of the two sides of the lower protective shell. A limiting protrusion is provided at the end of the snap-fit ​​block extending beyond the edge of the upper protective shell. A limiting opening is provided at the bottom of the side of the snap-fit ​​groove to accommodate the limiting protrusion. The upper and lower protective shells are fixed together by the snap-fit ​​action of the snap-fit ​​block and the snap-fit ​​groove. Both the snap-fit ​​block and the snap-fit ​​groove are made of elastic material.

[0009] Furthermore, the protective shell is provided with a limiting component inside. The limiting component includes three sets located in the middle section and both ends of the protective shell. Each set of limiting components includes two limiting rings arranged opposite each other. The inner diameter of the limiting rings is slightly smaller than the outer diameter of the water hose after water is introduced. Several transverse partitions are arranged parallel to each other between the two limiting rings. The limiting ring located on the outer side of the limiting component located at both ends of the protective shell is integrally connected to the edge of the opening at both ends of the protective shell.

[0010] Furthermore, a warning component is provided on the surface of the protective shell. The warning component is formed in several grooves on the side of the protective shell, and a strobe light is provided inside the groove.

[0011] Through the above technical solutions, the water hose that expands with water is embedded in the gap of the cross diaphragm to limit the position of the protective sleeve, preventing the protective sleeve from sliding freely on the surface of the water hose and affecting the protective effect.

[0012] The above technical solutions involve installing protective sleeves over fire hoses and / or hose couplings to prevent wear and tear from friction and collisions with sharp objects during the dragging of the fire hoses. Because the protective sleeves are roughly rugby ball-shaped, they can easily overcome obstacles, further enhancing their protective function. Limiting components are used to fix the position of the protective sleeves, and warning components are used to indicate the hoses in nighttime environments to prevent them from being stepped on and damaged.

[0013] The above technical solutions allow for the selective activation and deactivation of strobe lights during the installation of protective covers, depending on the working environment. This serves as a warning signal in dimly lit environments, preventing damage to hoses caused by stepping on them and threatening personal safety.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model can protect the middle section and joint of the fire hose by arranging them at intervals, preventing the fire hose from being damaged by friction and collision with sharp objects during operation. The inclined surfaces at both ends of the protective sleeve can better adapt to complex ground conditions and reduce dragging resistance.

[0016] 2. This utility model patent enables quick installation and disassembly through the snap-fit ​​component, without the need for additional fixing parts, which is convenient and efficient; the protective sleeve is fixed in position by the limiting component to ensure that it does not slip between itself and the fire hose.

[0017] 3. This utility model patent uses a strobe light for outlining and warning, alerting workers to the location of the hose in dim environments, and preventing them from stepping on or colliding with the hose, which could cause hose damage or injury. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] This embodiment proposes an olive-shaped water hose drag-resistant protective sleeve, such as... Figure 1 As shown, the main body of the protective sleeve is the protective shell 1. The protective shell 1 is a hollow structure with openings at both ends to accommodate the hose or hose connector. The outer surface is shaped like an oval, wider in the middle and narrower at both ends. The protective shell 1 gradually tapers from the middle to both sides to form an inclined surface. Two grooves 5 are provided on the upper and lower surfaces of the protective shell 1. Stroboscopes 6 are installed in the grooves 5 to form a warning assembly for outlining and warning in dim working environments. The protective shell 1 is formed by the upper protective shell 101 and the lower protective shell 102 being snapped together by a snap-fit ​​assembly.

[0025] like Figure 2 and Figure 3As shown, the protective shell 1 is divided into an upper protective shell 101 and a lower protective shell 102 along its transverse direction. The edges of the upper and lower protective shells 101 and 102 are provided with snap-fit ​​components. Inside the upper and lower protective shells 101 and 102, three sets of limiting components are provided at both ends and the middle section. Each limiting component consists of two opposing limiting rings 401 and a horizontally spaced partition 402 between the limiting rings 401. One of the limiting rings 401 located at both ends... The edges of the openings at both ends of the protective housing 1 coincide with those of the protective housing 1. After installation, the water hose is embedded in the gap of the horizontal partition 402 to fix the position of the protective sleeve. Three snap-fit ​​blocks 2 are provided on each side edge of the upper protective housing 101. The snap-fit ​​blocks 2 extend out of the edge of the upper protective housing 101 and are provided with limiting protrusions 201. Snap-fit ​​grooves 3 are opened at corresponding positions on both sides of the lower protective housing 102. The bottom side of the snap-fit ​​groove 3 is provided with a limiting opening 301 that matches the size of the limiting protrusions 201. Both the snap-fit ​​blocks 2 and the snap-fit ​​grooves 3 are made of elastic material.

[0026] Working process and principle: The protective sleeve in this embodiment can be flexibly installed according to the ground conditions where the fire hose is operated. It can simultaneously protect the middle section and joints of the fire hose, preventing damage from friction and collision with sharp objects during operation and dragging. The inclined surfaces at both ends of the protective sleeve can better adapt to complex ground conditions, reduce dragging resistance, and improve the ability to overcome obstacles. Figure 4 As shown, during installation, the snap-fit ​​block 2 is aligned with and inserted into the snap-fit ​​groove 3 at the corresponding position. The limiting protrusion 201 at the end of the snap-fit ​​block 2 is inserted into the limiting opening 301 on the side of the corresponding snap-fit ​​groove 3 to complete the locking and fixing. If working in the dark or dim environment, the strobe light 6 located in the groove 5 is turned on at the same time to indicate the outline and prevent personnel from stepping on it and damaging it. During disassembly, since both the snap-fit ​​block 2 and the snap-fit ​​groove 3 are made of elastic material, the limiting protrusion 201 on one side can be pressed at the same time to make it detach from the limiting opening 301. Then, the upper half of the protective shell 101 is lifted to make the snap-fit ​​block 2 detach from the snap-fit ​​groove 3. The operation is repeated on the other side edge to remove the upper half of the protective shell 101 and the lower half of the protective shell 102 separately to complete the disassembly work.
