Description

Technical Field

[0001] This invention belongs to the field of vehicle disinfection technology, specifically a disinfection spray device for coal transport vehicles. Background Technology

[0002] Coal mining construction sites are densely populated with people and vehicles frequently enter and exit the sites. There is a risk of viral and bacterial infection when vehicles are driving and transporting goods. To ensure the safety of construction workers, vehicles entering the sites need to be disinfected. Generally, disinfectant is sprayed from nozzles to disinfect the surface of coal trucks.

[0003] A patent with publication number CN220695593U discloses a mobile spray device for vehicle disinfection. By setting an adjustable spacing bracket, the side atomizing nozzles can fully contact and disinfect vehicles of different sizes. A backflow plate and a wastewater collection tank are installed in the base so that the disinfection wastewater is collected and treated uniformly. The outer cover effectively prevents strong winds from blowing away the atomized disinfectant, thereby improving the utilization rate of the disinfectant.

[0004] In the aforementioned prior art, when disinfecting transport vehicles entering and leaving coal mining areas, the coal trucks have a lot of coal dust on their surfaces. When spraying disinfectant on the coal trucks, the coal dust may clog the nozzles. Since the vehicles are large, the nozzles are generally positioned high, making it difficult to clean them after they become clogged.

[0005] Therefore, the present invention provides a disinfection spray device for coal transport vehicles. Summary of the Invention

The output end of the electric telescopic rod is slidably disposed on one side of the slide rail via a slider.

[0009] Preferably, the lower ends of the spray components on both sides are respectively provided with shielding components. The shielding components include a seventh rectangular strip that is slidably provided on one side of the U-shaped frame, and a telescopic plate is fixedly connected to one side of the seventh rectangular strip.

[0010] Preferably, a second telescopic component is provided on one side of the shielding component. The second telescopic component has the same structure as the first telescopic component. The shielding component also includes an eighth rectangular strip fixed to the side of the telescopic plate away from the seventh rectangular strip. The fourth rectangular strip passes through the telescopic plate and is fixed to the eighth rectangular strip.

[0011] Preferably, the eighth rectangular strip is provided with rubber pads on the side away from the telescopic plate.

[0012] Preferably, a first rectangular plate is fixedly connected to both sides of the first rectangular box, a first rectangular strip is slidably disposed on the side of the first rectangular plate, a first rectangular frame is fixedly connected to one side of the first rectangular strip, and the belt is rotatably disposed in the middle of the first rectangular frame located on one side of the first rectangular box.

[0013] Preferably, the first rectangular box is provided with soaking components on the side away from the belt. The soaking components include a sponge in the middle of the first rectangular box, a second rectangular plate slidably provided on one side of the sponge, and a plurality of L-shaped tubes passing through one side of the second rectangular plate. The upper ends of the L-shaped tubes are all fixedly connected to a second rectangular strip. Rectangular grooves are provided on both sides inside the first rectangular box. A rectangular slider is slidably provided inside the rectangular groove. The rectangular slider is fixedly connected to both sides of the sponge. The rectangular slider is fixedly connected to one side inside the rectangular groove by a spring.

[0014] Preferably, a connecting pipe is fixedly connected to one side of the second rectangular strip, the interior of the second rectangular strip is hollow, the second rectangular strip is connected to the interior of the connecting pipe, a third rectangular strip is fixedly connected to one side of the connecting pipe, the interior of the third rectangular strip is hollow and is connected to the interior of the connecting pipe, and the third rectangular strip is fixedly connected to the sixth rectangular strip through a rectangular block.

[0015] Preferably, a perforated plate is fixed to the lower end of the U-shaped frame, a base plate is provided at the lower end of the perforated plate, and a second rectangular box is fixed to both sides of the perforated plate and the base plate, and a beveled block is fixed to the other two sides of the second rectangular box and the base plate.

[0016] Preferably, the second rectangular box is equipped with a cleaning wheel that rotates inside.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a disinfection spray device for coal transport vehicles. A first rectangular frame with a sponge in its center is slid to one side of a first rectangular box. At this point, the atomizing nozzle is located inside the first rectangular box, with the sponge positioned to one side of the atomizing nozzle. A cleaning solution of baking soda and water is then introduced into a second rectangular strip. The sponge absorbs the solution, and the sponge contacts the atomizing nozzle, soaking it and loosening any impurities inside. The first rectangular strip is then slid to one side of a first rectangular plate, causing the first rectangular frame with a belt in its center to slide towards the first rectangular box until it reaches the center. The first rectangular frame and belt then press tightly against the surface of the atomizing nozzle. The belt's rotation cleans the surface of the atomizing nozzle, solving the problem of cumbersome cleaning after prolonged disinfection spraying causes clogging of the atomizing nozzle.

[0018] 2. The coal transport vehicle disinfection spraying device of the present invention involves a fourth rectangular bar sliding in the middle of the seventh rectangular bar, causing the eighth rectangular bar to be tightly attached to the top of the car tire. The side of the eighth rectangular bar that contacts the coal transport vehicle is provided with a relatively soft rubber pad, so that when the rubber pad contacts the side wall of the coal transport vehicle, it can be tightly attached to the surface of the coal transport vehicle, thereby causing the telescopic plate to extend and block the disinfectant sprayed from above, preventing the disinfectant from contacting the car tire and causing corrosion.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1 like Figures 1-3 As shown in the embodiment of the present invention, a disinfection spraying device for coal transport vehicles includes a U-shaped frame 1. Spraying components are provided on both sides and the top of the U-shaped frame 1. The spraying components include a first rectangular box 11 slidably disposed on one side of the U-shaped frame 1. A fourth rectangular strip 12 slidably passes through the middle of the first rectangular box 11. A fifth rectangular strip 121 is fixedly connected to one side of the fourth rectangular strip 12. A plurality of atomizing nozzles 122 are fixedly connected to the side of the fifth rectangular strip 121 away from the first rectangular box 11. A cleaning component is provided on one side of the first rectangular box 11. The cleaning component includes a belt 118 slidably disposed on one side of the first rectangular box 11. A brush is provided on the surface of the belt 118.

[0023] Specifically, coal mining construction sites are densely populated with frequent vehicle traffic. When vehicles transport goods to special locations, such as hospitals, there is a risk of viral and bacterial infections. Therefore, it is necessary to disinfect vehicles entering and leaving coal mining areas to ensure the safety of loading and unloading personnel. A U-shaped frame 1 is installed at the entrance and exit of the coal mining area. When coal trucks enter or leave the mining area, they pass through the middle of the U-shaped frame 1. This drives the first rectangular box 11, which in turn drives the atomizing nozzles 122 to slide inside the U-shaped frame 1 on both sides and the top, spraying disinfectant onto the sides and top of the coal truck. After disinfection, the fourth rectangular bar 12 is driven to slide in the middle of the first rectangular box 11. The fifth rectangular bar 121 drives the atomizing nozzle 122 to slide into the first rectangular box 11. Then, the drive belt 118 slides to one side of the atomizing nozzles 122 and fits into place. The belt 118 is driven by two rotating wheels. The rotation of the driving wheels drives the belt 118 to rotate. The belt 118 drives the brush to rotate on the surface of the atomizing nozzle 122 to clean the atomizing nozzle 122. There is no need to manually disassemble the atomizing nozzle 122 for cleaning. The cleaning process is relatively fast and convenient.

[0024] like Figure 4 As shown, a first telescopic component is provided on one side of the spray assembly. The first telescopic component includes a sixth rectangular bar 14 fixedly connected to one end of the fourth rectangular bar 12 away from the fifth rectangular bar 121. An electric telescopic rod 141 is fixedly connected to the middle of the sixth rectangular bar 14. A slide rail 142 is fixedly connected to one side of the electric telescopic rod 141 corresponding to one side of the U-shaped frame 1. The output end of the electric telescopic rod 141 is slidably set on one side of the slide rail 142 by a slider.

[0025] Specifically, by extending the electric telescopic rod 141, the fourth rectangular bar 12 slides, and the fourth rectangular bar 12 moves the atomizing nozzle 122 through the fifth rectangular bar 121, thereby adjusting the distance between the atomizing nozzle 122 and the coal car, which can be applied to coal cars of different sizes.

[0026] like Figure 5 As shown, the lower ends of the spray components on both sides are respectively provided with shielding components. The shielding components include a seventh rectangular strip 2 that is slidably provided on one side of the U-shaped frame 1, and a telescopic plate 21 is fixedly connected to one side of the seventh rectangular strip 2.

[0027] Specifically, since the main component of the disinfectant is sodium hypochlorite, which is acidic and has strong oxidizing and corrosive properties, although direct spraying onto tires may not cause immediate serious damage, prolonged contact can damage the tire's rubber material. When disinfecting coal trucks, the telescopic plate 21 is extended and placed tightly against the upper part of the truck's tires. The atomizing nozzle 122 is positioned above the telescopic plate 21 during spraying to prevent the disinfectant from contacting the tires and reduce corrosion.

[0028] like Figure 5 As shown, a second telescopic component is provided on one side of the shielding component. The second telescopic component has the same structure as the first telescopic component. The shielding component also includes an eighth rectangular bar 22 fixedly connected to the side of the telescopic plate 21 away from the seventh rectangular bar 2. The fourth rectangular bar 12 passes through the telescopic plate 21 and is fixedly connected to the eighth rectangular bar 22.

[0029] Specifically, by driving the electric telescopic rod 141 to retract, the fourth rectangular bar 12 slides. The fourth rectangular bar 12 slides in the middle of the seventh rectangular bar 2, causing the eighth rectangular bar 22 to be close to the top of the car tire, thereby causing the telescopic plate 21 to extend and block the disinfectant sprayed from above, preventing the disinfectant from contacting the car tire and causing corrosion.

[0030] like Figure 5 As shown, the eighth rectangular strip 22 has rubber pads on the side away from the telescopic plate 21.

[0031] Specifically, due to the uneven surface of the coal truck, a relatively soft rubber pad is provided on the side of the eighth rectangular strip 22 that contacts the coal truck, so that the rubber pad can fit tightly against the surface of the coal truck when it contacts the side wall of the coal truck, preventing leakage when spraying disinfectant.

[0032] like Figure 3 As shown, a first rectangular plate 111 is fixedly connected to both sides of the first rectangular box 11, a first rectangular strip 112 is slidably arranged on the side of the first rectangular plate 111, a first rectangular frame 113 is fixedly connected to one side of the first rectangular strip 112, and a belt 118 is rotatably arranged in the middle of the first rectangular frame 113 located on one side of the first rectangular box 11.

[0033] Specifically, by driving the first rectangular bar 112 to slide on one side of the first rectangular plate 111, the first rectangular bar 112 drives the first rectangular frame 113, which has a belt 118 in the middle, to slide towards the side of the first rectangular box 11 until it slides to the middle of the first rectangular box 11. At this time, the atomizing nozzle 122 is located inside the first rectangular box 11. The first rectangular frame 113 drives the belt 118 to stick tightly to the surface of the atomizing nozzle 122. Then, driving the belt 118 to rotate can clean the surface of the atomizing nozzle 122.

[0034] like Figure 3As shown, the first rectangular box 11 is provided with soaking components on the side away from the belt 118. The soaking components include a sponge 116 in the middle of the first rectangular frame 113, a second rectangular plate 114 slidably provided on one side of the sponge 116, and several L-shaped tubes 117 passing through one side of the second rectangular plate 114. The upper ends of the L-shaped tubes 117 are all fixedly connected to a second rectangular strip 1171. Rectangular grooves 1131 are provided on both sides inside the first rectangular frame 113. A rectangular slider 1132 is slidably provided inside the rectangular groove 1131. The rectangular slider 1132 is fixedly connected to both sides of the sponge 116. The rectangular slider 1132 is fixedly connected to one side inside the rectangular groove 1131 by a spring 1133.

[0035] Specifically, when there is a lot of dust inside the atomizing nozzle 122, it will cause the nozzle to become clogged. Soaking it before cleaning can loosen the dust. The first rectangular frame 113 with a sponge 116 in the middle is slid to one side of the first rectangular box 11. At this time, the atomizing nozzle 122 is located inside the first rectangular box 11, and the sponge 116 is located on one side of the atomizing nozzle 122. Then, a cleaning solution of baking soda and water is introduced into the second rectangular strip 1171. The sponge 116 then absorbs the solution and contacts the atomizing nozzle 122. Through the stretching of the spring 1133, the rectangular slider 1132 is driven to slide in the rectangular groove 1131, thereby causing the sponge 116, which has absorbed the cleaning water, to stick tightly to the atomizing nozzle 122 for soaking. This loosens the impurities on the surface of the atomizing nozzle 122 before the belt 118 is driven to clean the surface of the atomizing nozzle 122, making the cleaning more thorough.

[0036] like Figure 6 As shown, a connecting pipe 1172 is fixedly connected to one side of the second rectangular strip 1171. The interior of the second rectangular strip 1171 is hollow and communicates with the interior of the connecting pipe 1172. A third rectangular strip 1173 is fixedly connected to one side of the connecting pipe 1172. The interior of the third rectangular strip 1173 is hollow and communicates with the interior of the connecting pipe 1172. The third rectangular strip 1173 is fixedly connected to the sixth rectangular strip 14 through a rectangular block 1174.

[0037] Specifically, the cleaning fluid is introduced into the third rectangular strip 1173, then flows into the second rectangular strip 1171 through the connecting pipe 1172, and then flows into the sponge 116 through the L-shaped pipe 117 for adsorption. When the first rectangular box 11 drives the atomizing nozzle 122 to move on one side of the U-shaped frame 1, the sixth rectangular strip 14 drives the third rectangular strip 1173 to move through the rectangular block 1174, so that the sponge and the atomizing nozzle 122 always move in the same direction.

[0038] Example 2 like Figure 1 , Figure 7As shown in the first embodiment, another embodiment of the present invention is as follows: a hollow plate 3 is fixedly connected to the lower end of the U-shaped frame 1, a base plate 32 is provided at the lower end of the hollow plate 3, a second rectangular box 33 is fixedly connected to both sides of the hollow plate 3 and the base plate 32, and a beveled block 31 is fixedly connected to the other two sides of the second rectangular box 33 and the base plate 32.

[0039] Specifically, the two inclined blocks 31 on both sides of the perforated plate 3 and the base plate 32 allow the vehicle to move smoothly to the middle of the U-shaped frame 1. When the disinfectant sprayed by the atomizing nozzle 122 disinfects the coal truck, the excess disinfectant flows through the perforated plate 3 to the space between the perforated plate 3 and the base plate 32, and then flows into the second rectangular box 33. A sewage pump is installed on one side of the second rectangular box 33 to extract the disinfectant mixed with coal ash to prevent environmental pollution.

[0040] like Figure 7 As shown, a cleaning wheel 332 is rotatably mounted inside the second rectangular box 33.

[0041] Specifically, when using the atomizing nozzle 122 to spray disinfectant on the surface of the coal truck, the mixture of disinfectant and coal ash may result in a lot of sediment, making it impossible to extract the wastewater. By driving the cleaning wheel 332 to rotate, excessive sedimentation is prevented, ensuring that the wastewater can be discharged smoothly.

[0042] Working principle: When the coal truck enters or exits the mining area, it travels over the inclined block 31 on the upper end of the perforated plate 3, allowing it to enter the U-shaped frame 1. The retraction of the electric telescopic rod 141 causes the fourth rectangular bar 12 to slide. The fourth rectangular bar 12 slides in the middle of the seventh rectangular bar 2, causing the eighth rectangular bar 22 to press tightly against the top of the truck tires. A relatively soft rubber pad is provided on the side of the eighth rectangular bar 22 that contacts the coal truck, ensuring a tight fit against the truck's sidewall. This causes the telescopic plate 21 to extend, blocking the disinfectant sprayed from above and preventing it from contacting the truck tires. Corrosion is prevented when the atomizing nozzle 122 is positioned above the telescopic plate 21 during spraying, thus preventing the disinfectant from contacting the car tires and reducing corrosion. Subsequently, the electric telescopic rod 141 is extended, causing the fourth rectangular bar 12 to slide. The fourth rectangular bar 12 moves the atomizing nozzle 122 through the fifth rectangular bar 121, thereby adjusting the distance between the atomizing nozzle 122 and the coal car. This can be applied to coal cars of different sizes. Then, the first rectangular box 11 is driven to move the atomizing nozzle 122 inside the U-shaped frame 1, causing the atomizing nozzle 122 to spray disinfectant on both sides and the top of the coal car. The cleaning solution is introduced into the third rectangular strip 1173, then flows into the second rectangular strip 1171 through the connecting pipe 1172, and then into the sponge 116 through the L-shaped pipe 117 for adsorption. When the first rectangular box 11 moves the atomizing nozzle 122 on one side of the U-shaped frame 1, the sixth rectangular strip 14 moves the third rectangular strip 1173 through the rectangular block 1174, ensuring that the sponge and the atomizing nozzle 122 always move in the same direction. When there is a lot of dust inside the atomizing nozzle 122, it will cause the nozzle to become clogged. Soaking before cleaning can loosen the dust. The first rectangular frame 113, which has the sponge 116 in the middle, is slid to one side of the first rectangular box 11. At this time, the atomizing nozzle 122 is located inside the first rectangular box 11, so that the sponge 116 is located on one side of the atomizing nozzle 122, and then flows into the second rectangular strip 1171. A cleaning solution of baking soda and water is introduced into the nozzle, which is then absorbed by the sponge 116. The sponge 116 contacts the atomizing nozzle 122. Through the stretching of the spring 1133, the rectangular slider 1132 slides within the rectangular groove 1131, thereby causing the sponge 116, which has absorbed the cleaning water, to adhere tightly to the atomizing nozzle 122 for soaking. By driving the first rectangular bar 112 to slide on one side of the first rectangular plate 111, the first rectangular bar 112 drives the first rectangular frame 113, which has a belt 118 in the middle, to slide towards the side of the first rectangular box 11 until it slides to the middle of the first rectangular box 11. At this time, the atomizing nozzle 122 is located inside the first rectangular box 11. The first rectangular frame 113 drives the belt 118 to adhere tightly to the surface of the atomizing nozzle 122. Then, driving the belt 118 to rotate can clean the surface of the atomizing nozzle 122 more thoroughly. When the disinfectant sprayed from the atomizing nozzle 122 disinfects the coal truck, excess disinfectant flows through the perforated plate 3 to between the perforated plate 3 and the bottom plate 32, and then flows into the second rectangular box 33. A sewage pump is installed on one side of the second rectangular box 33 to extract the disinfectant mixed with coal ash to prevent environmental pollution. When the atomizing nozzle 122 is used to spray disinfectant on the surface of the coal truck, the mixture of disinfectant and coal ash may cause a lot of sediment, making it impossible to extract the sewage. By driving the cleaning wheel 332 to rotate, excessive sediment is prevented, ensuring that the sewage can be discharged smoothly.
