Description

Technical Field

[0001] The invention relates to the technical field of high-end fire-fighting equipment for fire-fighting robots, and in particular to an olive-type water hose dragging resistance protective cover. Background Art

[0002] Fire hoses are used to transport large amounts of water or other fire extinguishing agents (such as foam) to the fire source at the fire scene. When dealing with different fire source locations, the fire hose needs to be dragged and slid on the ground. When encountering more complex ground conditions, wear protection for the hose and hose joints is particularly necessary. With the widespread use of firefighting robots, since firefighting robots cannot achieve the flexibility of humans, it is easy to damage the hose or hose joints during the dragging process, causing delays or delays in firefighting and rescue.

[0003] After searching, it was found that the Chinese patent with announcement number CN215938868U discloses an anti-detachment water hose protective cover, which includes a sleeve. After the water hose and the joint are bundled, the notch is opened and the sleeve is clamped on the water hose at the joint connection to achieve protection of the water hose at the joint connection; the Chinese patent with announcement number CN214860807U discloses a new type of water hose protective cover, which effectively prevents the damage caused by the friction between the water hose and the ground and the internal damage of the water hose caused by collision at the joint connection by setting a first sleeve and a second sleeve.

[0004] The above two types of hose protection covers focus on protecting the hose joints, and both use bolt and nut structures for installation and fixation. The installation process is not simple and efficient, and there are certain limitations. At the same time, the shape of the existing protection cover is still a long cylinder, which is not conducive to the robot crossing obstacles when dragging the hose.

[0005] Therefore, in order to solve the above problems, a related facility that better meets the usage requirements is needed. Summary of the invention

[0006] In view of this, the purpose of the present invention is to propose an olive-shaped water hose dragging resistance protective cover to solve the problem that the existing protective cover is inconvenient to cross obstacles when protecting the water hose or the water hose joint and the installation process is not simple and efficient.

[0007] Based on the above-mentioned purpose, the present invention provides an olive-shaped water hose dragging anti-resistance protective cover, including a protective outer shell, the two ends of the protective outer shell are open and a cavity is formed inside to accommodate a water hose or a water hose joint, the protective outer shell is in the shape of an American football with a large middle and small ends, and the protective outer shell gradually shrinks 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 along its transverse section, and a clamping assembly is arranged at the edges of the upper protective shell and the lower protective shell. The clamping assembly includes a clamping block and a clamping groove, the clamping block is arranged at the middle and both ends of the edges of both sides of the upper protective shell, and the clamping groove is arranged at the middle and both ends of the edges of both sides of the lower protective shell. The clamping block extends out of the edge end of the upper protective shell and is provided with a limiting protrusion, and a limiting opening for accommodating the limiting protrusion is opened through the bottom of the side of the clamping groove. The upper protective shell and the lower protective shell are fixed together by the clamping action of the clamping block and the clamping groove. The clamping block and the clamping groove are both made of elastic material.

[0009] Furthermore, a limit assembly is arranged inside the protective shell, and the limit assembly includes three groups arranged in the middle section and both ends of the protective shell, each group of limit assemblies includes two relatively arranged limit rings, the inner diameter of the limit ring is slightly smaller than the outer diameter of the water hose after water passes through, and a number of cross partitions are arranged in parallel between the two limit rings. The limit rings located on the outside of the limit assemblies arranged at both ends of the protective shell are integrally connected with the edges of the openings at both ends of the protective shell.

[0010] Furthermore, a warning component is arranged on the surface of the protective shell, and the warning component is provided with a plurality of grooves on the side of the protective shell, and a strobe light is arranged inside the grooves.

[0011] Through the above technical solution, the water-permeable and inflated water hose is embedded in the gap between the diaphragms to limit the position of the protective sleeve, thereby preventing the protective sleeve from sliding freely on the surface of the water hose and affecting the protective effect.

[0012] Through the above technical solution, a protective cover is set on the outside of the fire hose and / or the hose joint to prevent the fire hose from being worn and broken due to friction and collision with sharp objects during dragging. Since the shape of the protective shell is similar to that of a rugby ball, it is easy to pass over obstacles, thus further playing a protective role. The limit component is used to fix the position of the protective cover, and the warning component is used to indicate the outline in a night environment to prevent the hose from being stepped on and damaged.

[0013] Through the above technical solution, the strobe light can be turned on and off when installing the protective cover according to the working environment, which plays a role of warning in dim environment and prevents the water hose from being damaged and threatening personal safety.

[0014] Beneficial effects of the present invention: 1. The present invention can protect the middle section and joints of the hose through interval arrangement to prevent the fire hose from being damaged by friction and collision with sharp objects during the dragging process. The inclined surfaces designed at both ends of the protective cover can better adapt to complex ground conditions and reduce dragging resistance.

[0015] 2. The patent of this invention can realize quick installation and disassembly through the snap-on assembly, without the need for additional fixing parts, which is convenient and efficient; the position of the protective cover is fixed by the limit assembly to ensure that there is no slippage between it and the fire hose.

[0016] 3. The patent of the present invention installs a strobe light for outline warning, which can warn the passing workers of the position of the water hose in a dim environment to prevent the water hose from being damaged and people from being injured by stepping on or colliding with the water hose.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0020] This embodiment proposes an olive-shaped hose drag resistance protective cover, such as Figure 1 As shown, the main body of the protective cover is a protective shell 1, which is a cavity structure with two openings at both ends to accommodate a hose or a hose joint. The outer surface is in the shape of a rugby ball with a large middle and small ends. The protective shell 1 gradually shrinks from the middle section to both sides to form an inclined surface. Two grooves 5 are respectively provided on the upper and lower surfaces of the protective shell 1. Strobe lights 6 are arranged in the grooves 5 to form a warning component for indicating the outline in a dim working environment. The protective shell 1 is formed by an upper half protective shell 101 and a lower half protective shell 102 connected by a clamping component.

[0021] 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 section, and a clamping assembly is arranged at the edges of the upper protective shell 101 and the lower protective shell 102. Three groups of limiting assemblies are arranged at both ends and the middle section of the upper protective shell 101 and the lower protective shell 102. Each group of limiting assemblies is composed of two limiting rings 401 arranged opposite to each other and a horizontal partition 402 arranged between the limiting rings 401. The limiting rings 401 on one side of the limiting assemblies at the two ends are arranged at the same time. 1 coincides with the opening edges of both ends of the protective shell 1, and after installation, the water hose is embedded in the gap of the transverse partition 402 to fix the position of the protective cover; three clamping blocks 2 are respectively arranged on the edges of both sides of the upper protective shell 101, and the clamping blocks 2 extend out of the edge ends of the upper protective shell 101 to set limiting protrusions 201, and the corresponding positions of the edges of both sides of the lower protective shell 102 are provided with clamping grooves 3, and the bottom of the side of the clamping groove 3 is penetrated with a limiting opening 301 that is adapted to the size of the limiting protrusion 201, and the clamping blocks 2 and the clamping grooves 3 are both made of elastic material.

[0022] Working process and principle: The protective cover of this embodiment can be flexibly installed according to the ground conditions of the fire hose operation, and can protect the middle section and joints of the fire hose at the same time to prevent the fire hose from rubbing against sharp objects and being damaged during the dragging process. The inclined surfaces designed at both ends of the protective cover can better adapt to complex ground conditions, reduce drag resistance, and improve the ability to cross obstacles. Figure 4 As shown, during installation, the clamping block 2 is aligned with and embedded in the clamping groove 3 at the corresponding position, and the limiting protrusion 201 at the end of the clamping block 2 is embedded in the limiting opening 301 on the side of the corresponding clamping groove 3 to complete the locking and fixing; if the operation is carried out at night or in a dim environment, the strobe light 6 located in the groove 5 is turned on during installation to indicate the outline warning and prevent people from stepping on and damaging it; during disassembly, since the clamping block 2 and the clamping groove 3 are made of elastic materials, the limiting protrusion 201 on one side can be pressed at the same time to disengage it from the limiting opening 301, and then the upper protective shell 101 can be lifted to disengage the clamping block 2 from the clamping groove 3, and the operation is repeated on the other side edge to separate the upper protective shell 101 and the lower protective shell 102 to complete the disassembly work.
