Embodiment

[0026] An embodiment of the present invention provides a water inlet grill of a water jet propulsion device. Figure 1 to Figure 3 Schematic diagram of the structure of the water inlet grid provided by the embodiment of the present invention. Such as figure 1 , figure 2 with image 3 As shown, the water inlet grill includes longitudinal grill units and a plurality of horizontal grill bars 1 arranged in parallel and at intervals. The longitudinal grid unit includes: a distance adjusting link mechanism 3 , a driving device and at least two longitudinal grid bars 4 . Each longitudinal grid bar 4 is provided with a notch 4a at a position corresponding to each horizontal grid bar 1 (see Figure 5 ), each horizontal grid bar 1 is snapped into the corresponding notch 4a. A spacing adjustment link mechanism 3 is connected between any two adjacent longitudinal grid bars 4 in the longitudinal grid unit, and the spacing adjustment link mechanism 3 is configured to adjust the corres...

Abstract

The invention discloses a water inlet grille of a water spraying propelling device, and belongs to the field of water spraying propelling device parts. The water inlet grille includes a longitudinal grille unit; the longitudinal grille unit includes distance adjustment connection rod mechanisms, a drive device, and at least two longitudinal grille bars; each longitudinal grille bar is perpendicular to horizontal grille bars; a recessed opening is formed in a position, corresponding to each horizontal grille bar, of each longitudinal grille bar; each horizontal grille bar is clamped in the corresponding recessed opening; a distance adjustment connection rod mechanism is connected between any two adjacent longitudinal grille bars; the drive device is connected to the distance adjustment connection rod mechanisms; and the distance adjustment connection rod mechanisms are configured to adjust a distance between the corresponding two longitudinal grille bars under the drive of the drive device. The water inlet grille can adapt to waste debris with different sizes, can effectively prevent waste debris from entering the water spraying propelling device, can ensure the water inlet amount, and can improve the working efficiency of the water spraying propelling device.

Description

technical field [0001] The invention relates to the field of water jet propulsion device accessories, in particular to a water inlet grill of a water jet propulsion device. Background technique [0002] The water jet propulsion device is a kind of propulsion tool for ships. After absorbing water from the bottom of the ship, the rotating impeller does work on the water flow, so that the water is ejected at high speed from the water outlet. Due to the presence of garbage in the water body, a water inlet grill needs to be arranged at the water inlet of the water jet propulsion device, and the water inlet grill is used to prevent garbage and debris from entering the interior of the water jet propulsion device. [0003] The existing water inlet grid includes a plurality of horizontal grid bars arranged in parallel with each other and a plurality of longitudinal grid bars arranged in parallel with each other. A plurality of longitudinal grid bars are respectively welded to a plur...
