Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to an environmentally friendly baffle cleaning device for municipal construction. Background Technology

[0002] In municipal infrastructure construction and maintenance projects, construction barriers are one of the core facilities for ensuring on-site safety and public order. They not only serve the basic function of separating construction areas from pedestrian and vehicle traffic spaces, but also effectively block the spread of dust and noise generated during construction, as well as prevent safety risks such as falling building materials and accidental entry of personnel. They are an important barrier for maintaining construction efficiency and the harmony of the urban public environment. However, during long-term outdoor use, barriers are easily affected by complex environmental factors and accumulate a large amount of stubborn stains. These stains come from a wide range of sources, including cement dust, sand and gravel particles, and paint residue generated during construction, as well as motor vehicle exhaust oil stains, road dust, and mud, sand, fallen leaves, and other debris deposited after rainwater runoff.

[0003] The existing cleaning method relies on workers to clean each panel one by one with rags, scrapers and other tools. It often takes 1-2 hours for a single person to clean one panel. If there are dozens of panels on a large construction site, a lot of manpower and time are required. At the same time, the labor intensity is extremely high. Workers need to bend over and climb (to clean the upper part of the panels) frequently. Long-term operation can easily cause back strain, falls from height and other safety hazards.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1-4 This utility model provides an environmentally friendly municipal construction baffle cleaning device, including a trolley 1. The trolley 1 has a water tank 101 on one side of its top and a cleaning box 2 on the other side. A base box 3 is located on the top of the trolley 1. The water outlet of the water tank 101 is connected to the top of the cleaning box 2 via a connecting pipe 103, and a valve body 102 is installed on the connecting pipe 103. Several nozzles 104 are installed on the top of the cleaning box 2, and the nozzles 104 are connected to the connecting pipe 103. An exhaust fan 201 is installed on the side wall of the cleaning box 2, and a filter screen 202 is installed inside the cleaning box 2. The cleaning box 2 rotates... The cleaning box 2 is equipped with a brush disc 203, and has a sludge inlet 204 on one side and a replacement port 205 on the side wall. The bottom box 3 is equipped with a dual-axis motor 301. Both output ends of the dual-axis motor 301 are connected to a drive shaft 302. The end of the drive shaft 302 is fixed with a first conical tooth 303. The first conical tooth 303 is engaged with a second conical tooth 304. The second conical tooth 304 is fixedly sleeved on the bottom end of the lead screw 305. The outer side of the lead screw 305 is threaded with a lifting sleeve 306. The top end of the lifting sleeve 306 is fixedly connected with a movable block 307. The movable block 307 is connected to the bottom of the cleaning box 2.

[0021] When cleaning the municipal construction barrier, the device is first moved to the side of the barrier to be cleaned using a trolley 1. Before cleaning, the dual-shaft motor 301 in the base box 3 is started according to the height of the barrier. The two output ends of the dual-shaft motor 301 drive the transmission shaft 302 to rotate. The first conical tooth 303 at the end of the transmission shaft 302 rotates synchronously with the transmission shaft 302. Since the first conical tooth 303 meshes with the second conical tooth 304, the second conical tooth 304 drives the lead screw 305 to rotate. When the lead screw 305 rotates, the lifting sleeve 306 on its outer side moves up and down along the axis of the lead screw 305. The movable block 307 at the top of the lifting sleeve 306 rises and falls synchronously with the lifting sleeve 306, thereby driving the cleaning box 2 to rise and fall, so that the sewage inlet 204 of the cleaning box 2 matches the height of the barrier.

[0022] After adjustment, insert the baffle into the cleaning box 2 through the sewage inlet 204, start the brush 203 in the cleaning box 2, and the brush 203 rotates to scrub the dirt on the surface of the baffle; at the same time, open the valve body 102 on the connecting pipe 103, and the water in the water tank 101 is transported to the nozzle 104 on the top of the cleaning box 2 through the connecting pipe 103. The nozzle 104 sprays water onto the surface of the baffle to assist the brush 203 in rinsing the dirt.

[0023] During the cleaning process, the exhaust fan 201 on the side wall of the cleaning box 2 is activated. The exhaust fan 201 draws the dust and debris generated during brushing into the cleaning box 2, preventing the dust from spreading to the outside. The wastewater and impurities generated during rinsing flow into the bottom of the cleaning box 2 and are filtered by the filter screen 202 inside the cleaning box 2. The impurities are trapped by the filter screen 202, and the filtered water can be centrally treated. If maintenance is required on components such as the filter screen 202 and brush disc 203 inside the cleaning box 2, it can be done through the replacement port 205 on the side wall of the cleaning box 2.

[0024] In a preferred embodiment, the bottom of the trolley 1 is equipped with casters with brakes, and a push handle is provided on one side of the trolley 1.

[0025] Push the handle on one side of the cart 1, and the casters at the bottom of the cart 1 will roll with the push force, enabling the device to move within the construction area; when the device moves to the target baffle, step on the brake on the casters, the casters will lock, and the device will be fixed in the current position to prevent displacement due to external forces during the cleaning process.

[0026] In a preferred embodiment, a sealing door is installed at the replacement port 205 via a hinge, and a sealing ring is provided between the sealing door and the cleaning box 2.

[0027] During routine cleaning, the sealing door at the replacement port 205 is closed, and the sealing ring between the sealing door and the cleaning box 2 fills the gap between them, preventing sewage and dust in the cleaning box 2 from leaking out of the replacement port 205. When it is necessary to replace the filter screen 202, repair the brush plate 203, or clean internal impurities, the sealing door can be opened by the hinge, and the internal components can be operated through the replacement port 205. After the operation is completed, the sealing door is closed, and the sealing ring re-seales.

[0028] In a preferred embodiment, the inner wall of the base box 3 is provided with a guide rail, and the two sides of the movable block 307 are provided with sliders adapted to the guide rail.

[0029] When the lead screw 305 inside the base box 3 rotates, it drives the lifting sleeve 306 and the movable block 307 to rise and fall. The sliders on both sides of the movable block 307 slide synchronously along the guide rails on the inner wall of the base box 3. The guide rails constrain the sliders, restricting the movement direction of the movable block 307, and only allowing it to rise and fall in the vertical direction.

[0030] In a preferred embodiment, two brush disks 203 are provided, and the two brush disks 203 rotate synchronously driven by a motor.

[0031] During cleaning, the motor starts and drives the two brush discs 203 to rotate synchronously (the rotation direction can be set to opposite or the same direction according to the cleaning needs). When the baffle is inserted into the cleaning box 2 from the dirt inlet 204, the two brush discs 203 contact the two sides of the baffle respectively. The friction generated by the rotation brushes the dirt on both sides of the baffle, and the water flow from the nozzle 104 washes the dirt away from the surface of the baffle.

[0032] In a preferred embodiment, the filter screen 202 is horizontally arranged inside the cleaning box 2, and there are two filter screens 202 in total.

[0033] The wastewater generated during cleaning, carrying impurities, flows into the bottom of the cleaning tank 2 and first passes through the first horizontally set filter screen 202, which traps larger particles of impurities.

[0034] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of an environmentally friendly municipal construction barrier cleaning device provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
