Description

Nozzle cascade swing cleaning device

Technical Field

The utility model relates to the field of cleaning devices, in particular to a nozzle cascade swing cleaning device.

Background Art

Tarpaulins are usually divided into two categories: coarse tarpaulins and fine tarpaulins. Coarse tarpaulins are also called tarpaulin covers. The fabric is strong and fold-resistant, and has good waterproof properties. It is used for automobile transportation, covering open-air warehouses, and setting up tents in the wild. The surface of the tarpaulin will become dirty after long-term use. In order to better reuse the tarpaulin, the tarpaulin needs to be cleaned regularly. The main cleaning method at present is to put the tarpaulin in a pool for cleaning. The tarpaulin has a large area and is not very heavy. The cleaning process in the pool is cumbersome and labor-intensive. There is also a handheld spray gun for washing the tarpaulin. The handheld spray gun has a limited coverage and low cleaning efficiency. Therefore, these two cleaning methods are only suitable for small batches of tarpaulin cleaning and need to be improved.

Implementation

Embodiment 1, referring to Figures 1-3 of the specification, a nozzle cascade swing cleaning device comprises a plurality of nozzle assemblies 11 installed at equal intervals on a support seat 17, a driving mechanism is installed between each nozzle assembly 11, and each nozzle assembly 11 is driven by the driving mechanism to swing synchronously.

The driving mechanism includes swing brackets 121 of the same number as the nozzle assembly 11. The swing brackets 121 are set to be in the shape of a long plate. The nozzle assembly 11 is fixedly installed on the side of the swing bracket 121. The lower end of the swing bracket 121 is hinged to the support seat 17. A driven connecting rod 122 is hinged between each swing bracket 121. An active connecting rod 123 is hinged in the middle of the swing bracket 121 at one end, and a reduction motor 124 is provided on the outer side of the swing bracket. A crank 125 is fixedly mounted on the output shaft of the reduction motor 124. The outer end of the crank 125 is hinged to the outer end of the active connecting rod 123. The reduction motor 124 drives the crank 125 to rotate, and the crank 125 drives the swing bracket 121 at one end to swing through the active connecting rod 123. Under the action of each driven connecting rod 122, the swing brackets 121 are linked to each other to achieve synchronous swinging.

The nozzle assembly 11 includes a nozzle 111 and a liquid inlet pipe 112. A joint 113 is vertically provided in the middle of the liquid inlet pipe 112. The joint 113 and the main pipeline 14 are connected by a flexible tube 13. When the nozzle assembly 11 swings with the swing bracket 121, the flexible tube 13 expands and contracts accordingly to keep the pipeline between the nozzle assembly 11 and the main pipeline 14 unobstructed.

A rotary joint 18 is also installed between the flexible pipe 13 and the main pipe 14 to reduce the deformation of the flexible pipe, increase the service life of the flexible pipe, and avoid the phenomenon that the thread joints at both ends of the flexible pipe are easily loosened.

The water spraying direction of the nozzle is consistent with the length direction of the swing bracket 121. Locking seat assemblies 15 are provided at both ends of the swing bracket 121. The locking seat assemblies 15 include a fixed block with an arc groove and a buckle block with an arc groove. The two locking seat assemblies 15 are locked at the two ends of the liquid inlet pipe 112, and the liquid inlet pipe 112 is matched and inserted between the two arc grooves.

The heights of two adjacent driven connecting rods 122 in the driving mechanism are different. One driven connecting rod 122 is hinged between the middle parts of the two swing brackets 121, and the other driven connecting rod 122 is hinged between the upper ends of the two swing brackets 121. The height difference is designed to limit the swing amplitude of the nozzle so that the coverage range of the nozzle is consistent with the size of the tarpaulin.

A U-shaped seat 16 is fixedly mounted on the support seat 17 , and the lower end of the swing bracket 121 is hinged in the U-shaped seat 16 . The U-shaped seat 16 is used to control the swing direction of the swing bracket 121 so that the swing bracket 121 can only swing in the length direction of the support seat 17 .

The use process of the utility model is as follows: when cleaning the tarpaulin, the tarpaulin is unfolded and laid under the cleaning device, and then the reduction motor 124 of the driving mechanism is started, the reduction motor 124 drives the crank 125 to rotate, and the crank 125 drives the swing bracket 121 at one end to swing through the active connecting rod 123. Under the connection action of each driven connecting rod 122, the swing brackets 121 are linked and swing synchronously and in the same direction, so that each nozzle 111 swings and sprays water synchronously, and the tarpaulin below is cleaned. The cleaning coverage of the tarpaulin is wide and the cleaning efficiency is high. At the same time, the water flow will be disturbed when the nozzle swings, and the disturbed water flow can clean the dirt on the surface of the tarpaulin more thoroughly, and the cleaning effect is good.
