Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that when an element is referred to as being "mounted on" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the present invention provides a sump 100, and the sump 100 may be applied to a fire fighting robot, a drain pipe, or other places. In this embodiment, the sump 100 is installed in the fire fighting robot and collects fluid for the fire fighting robot to perform fire fighting work.

specifically, as shown in fig. 2, the water collector 100 includes a housing 10, a plurality of branch pipes 20 and a turning plate 30, wherein the plurality of branch pipes 20 are respectively installed in the housing 10 and are communicated with the inside of the housing 10; the turning plate 30 is arranged along the axis of the housing 10, one end of the turning plate 30 is mounted on the inner wall of the housing 10, the other end of the turning plate 30 can seal one of the branch pipes 20, and the side of the turning plate 30 facing the branch pipe 20 is provided with a mastoid texture or a hole texture. It can be understood that by providing the mastoid texture 31 or the hole texture (not shown) on the side of the flap 30, the surface capacity of the flap 30 is improved, and the viscous resistance between the water flow and the side of the flap 30 is significantly reduced; furthermore, when the fluid in the branch pipe 20 impacts the flap 30, the friction between the water flow and the side surface of the flap 30 can be reduced, so that the loss of the kinetic energy of the fluid is reduced.

The branch pipes 20 are used for connecting a water hose, the number of the branch pipes 20 is 2, and the 2 branch pipes 20 are symmetrically arranged on the shell 10. The 2 branch pipes 20 and the housing 10 form a water collector 100 with a cross section of "Y". Of course, in other embodiments, the number of the branch pipes 20 may be other, such as 3, 4, which is not exhaustive here.

Further, the 2 branch pipes 20 are respectively a first branch pipe 21 and a second branch pipe 22, the fluids in the first branch pipe 21 and the second branch pipe 22 collide and converge at the other end of the flap 30, the collision angle between the fluid in the first branch pipe 21 and the fluid in the second branch pipe 22 is β, and β is less than 56 °.

The fluid impinging angle β in 2 legs 20 of the existing manifold 10 is greater than or equal to 56 degrees. When the water flow is converged, the larger the collision angle is (the stronger the impact between the two is), the more the kinetic energy is lost. It can be understood that, in the present embodiment, when the fluid in the first branch pipe 21 and the fluid in the second branch pipe 22 converge, the collision angle β is smaller than 56 °, that is, the collision angle when the fluids converge is reduced, so that the turbulent flow characteristic after the water flow converges is reduced, the laminar flow characteristic is increased, and the loss of kinetic energy is effectively reduced.

Optionally, the collision angle β between the fluid in the first branch pipe 21 and the fluid in the second branch pipe 22 is 45 ° ≦ β ≦ 56 °.
