Description

Technical Field

[0001] This utility model relates to the field of washing vehicle technology, and in particular to a washing vehicle with a front flushing mechanism. Background Technology

[0002] A sanitation or municipal cleaning vehicle is a specialized sanitation or municipal operation vehicle, mainly used to clean public areas such as roads, sidewalks, and curbs using high-pressure water jets.

[0003] The flushing mechanism is typically installed at the lower front or side front of the washing vehicle, positioned low and aimed at the road surface and curb base that need cleaning. It focuses on removing accumulated dirt, moss, and oil stains from the sidewalks and curb base. Road surfaces and curb bases are difficult and often overlooked areas for urban road cleaning, easily accumulating garbage, breeding bacteria, and affecting drainage and the city's appearance. The flushing mechanism works by utilizing the powerful impact and diffusion effect generated by the collision of two or more high-pressure water streams to efficiently remove stubborn dirt accumulated on the road surface and curb base.

[0004] Existing hedging mechanisms use solid tees. A tee is a pipe fitting with three openings (one inlet, two outlets; or two inlets, one outlet), used to split a pipe into two or merge two pipes into one. "Solid" means that the tee itself is a single, structurally complete, and enclosed metal part with a specific internal flow channel. It has three solid connection ends, which need to be threaded or welded to the main pipe and branch pipes. It is itself a separate, standard pipe fitting that requires additional installation. However, the installation of solid tees has the following disadvantages:

[0005] 1. Installation is troublesome: Solid tees require precise drilling, welding or threaded connection on the main pipe, which increases the installation steps, accuracy requirements and time. It also increases the number of connection steps and interfaces, becoming a potential source of leakage.

[0006] 2. High cost: The tee itself is an additional part, which increases the procurement cost; welding or threaded connection also requires labor costs and possible auxiliary material costs; it also increases the weight and volume of the system, and the internal structure of the tee generates unnecessary flow resistance or turbulence, affecting the stability of water flow.

[0007] Therefore, using it to draw out branch water flow in a hedging mechanism would lead to cumbersome installation steps, increased parts and processing costs, and a more complex system. Utility Model Content

[0008] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, a washing vehicle with a front flushing mechanism is provided.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a washing vehicle with a front flushing mechanism, including a flushing mechanism installed on the chassis of the washing vehicle. The flushing mechanism includes two sets of flushing supports, and flushing water pipes are installed on the flushing supports. The nozzles of the two flushing water pipes are spatially staggered in height along the axial direction, and the two flushing water pipes are spatially staggered in the lateral direction. The two flushing water pipes are independently controlled, and the spray holes of the flushing water pipes are arranged opposite each other. The spray directions of the spray holes of the two flushing water pipes are opposite.

[0010] Furthermore, the flushing water pipe includes a vertical rod and a horizontal rod. The vertical rod is installed on the flushing support. The vertical rod and the horizontal rod are connected by an arc-shaped pipe. The horizontal rod has an angle α with the horizontal plane, with the angle of angle α being 10° to 45°. The horizontal rod has an angle β with the vertical plane, with the angle of angle β being 30° to 70°.

[0011] Furthermore, the flushing water pipe is mounted on the flushing support by a locking assembly to prevent displacement of the flushing water pipe;

[0012] The locking assembly includes a first locking member and a second locking member. Both the first and second locking members have arc-shaped grooves on their contact surfaces. The first and second locking members are locked to the flushing support by bolts. The two arc-shaped grooves are joined together to form a complete mounting hole, and the flushing water pipe is installed in the mounting hole.

[0013] Furthermore, the flushing support includes a flushing bracket, and mounting plates are installed on both the upper and lower sides of the flushing bracket. An opening is provided at the suspended end of the mounting plate, and the flushing water pipe is located in the two openings.

[0014] Furthermore, the two mounting plates and the flushing bracket form an installation space, in which the locking assembly is installed.

[0015] Furthermore, the flushing water pipes are made of rigid material.

[0016] Furthermore, the lateral distance between the two sets of flushing supports is adjustable.

[0017] Furthermore, the vertical rod of the flushing water pipe is connected to the water source on the garbage truck.

[0018] The beneficial effects of this utility model are as follows: This utility model uses a closed-loop process of spatial staggered layout, dual-angle directional spraying, precise water flow collision, and water wedge stripping of dirt to efficiently solve the problem of dirt on public areas such as roads, sidewalks, and curbs in dynamic operation, while significantly reducing installation and maintenance costs and optimizing cleaning efficiency and reliability.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] like Figures 1-4 The washing vehicle shown includes a front flushing mechanism, which is mounted on the chassis of the washing vehicle. The flushing mechanism includes two sets of flushing supports 1, which are fixed on the chassis of the washing vehicle. They provide rigid support for the flushing water pipes 2 and also serve as a spatial positioning reference, determining the lateral distance and installation height of the two sets of flushing water pipes 2. They also have good vibration resistance and can resist the vibration caused by vehicle movement and water pressure impact. The lateral distance between the two sets of flushing supports 1 is adjustable.

[0027] The flushing support 1 is equipped with a flushing water pipe 2. The flushing water pipe 2 can be started / stopped and its pressure adjusted independently to flexibly deal with unilateral pollution or complex road conditions, reducing water waste. The flushing water pipe 2 generates a high-pressure counter-current water flow. The collision of the two opposing jets forms a "water wedge effect" to thoroughly remove dirt from the base of the curb. The flushing water pipe 2 is a rigid water pipe to ensure structural rigidity and maintain the stability of the flushing hole angle under high-frequency vibration, avoiding jet deviation caused by hose deformation. The nozzles of the two flushing water pipes 2 are spatially staggered in height along the axial direction and staggered in the lateral direction to avoid interference between the two flushing water pipes 2, eliminate the limitation of space under the vehicle, and ensure precise water flow convergence. The two flushing water pipes 2 are independently controlled, and the nozzles of the flushing water pipes 2 are set opposite to each other, with the spray directions of the nozzles of the two flushing water pipes 2 being opposite.

[0028] The flushing water pipe 2 includes a vertical rod 21 and a horizontal rod 22. The vertical rod 21 is installed on the flushing support 1. The vertical rod 21 of the flushing water pipe 2 is connected to the water source on the garbage truck. The vertical rod 21 and the horizontal rod 22 are connected by an arc-shaped pipe 23. The arc-shaped pipe 23 smoothly turns the vertical water flow into an inclined spray direction to reduce turbulence and pressure loss. The end outlet of the horizontal rod 22 is a flushing hole. The horizontal rod 22 has an angle α with the horizontal plane to control the water flow diving angle and ensure that the confluence point is close to the ground. The angle α is 10° to 45°.

[0029] The crossbar 22 has an angle β between it and the vertical plane, which controls the lateral deflection angle of the water flow, so that the two water flows collide precisely with the base of the curb stone. The angle β is 30° to 70°, thereby achieving cleaning of the four corners.

[0030] The flushing water pipe 2 is mounted on the flushing support 1 by the locking assembly 3 to prevent the flushing water pipe 2 from shifting.

[0031] The locking assembly 3 includes a first locking member and a second locking member. Both the first and second locking members have arc-shaped grooves on their contact surfaces. The first and second locking members are locked to the flushing support 1 by bolts, which facilitates disassembly or angle adjustment and eliminates the risk of loosening or deflection of the flushing water pipe 2 during long-term use. The two arc-shaped grooves are joined together to form a complete mounting hole 31. The flushing water pipe 2 is installed in the mounting hole 31. That is, the two arc-shaped grooves hold the flushing water pipe 2 tightly, resisting the backlash of high-pressure water flow and vehicle bumps.

[0032] The flushing support 1 includes a flushing bracket 11, and mounting plates 12 are installed on the upper and lower sides of the flushing bracket 11. An opening 13 is opened at the suspended end of the mounting plate 12. The flushing water pipe 2 is located in the two openings 13, allowing the flushing water pipe 2 to pass through and restricting its radial displacement, while facilitating quick assembly and disassembly.

[0033] The two mounting plates 12 and the flushing bracket 11 form an installation space, and the locking assembly 3 is installed in this installation space.

[0034] Work process (taking curb stones as an example):

[0035] Step 1: Drive the washing truck to the section of road to be washed, keeping the vehicle body parallel to the curb;

[0036] Step 2: Adjust the lateral spacing of the two sets of flushing supports 1 according to the position of the curbstone to ensure that the confluence of the two water channels covers the base of the curbstone and the flushing holes of the flushing water pipe 2 form a downward and outward spray direction.

[0037] Step 3: Connect flushing water pipe 2 to a water source equipped with a vehicle-mounted high-pressure water pump, and pressurize the water system for standby;

[0038] Step 4: High-pressure water smoothly turns through the arc-shaped pipe 23 from the vertical rod 21 and enters the horizontal rod 22. The water flow is accelerated and ejected from the flushing hole at the end of the horizontal rod 22, forming two independent and controllable high-pressure jets. The two jets collide at high speed at a preset point, completing the cleaning of dirt on the curbstone.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
