DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0020] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 11 , which is the first embodiment of the present invention, proposes a decontamination device for a steel grating, comprising: a base 1 having a nozzle 101; a brush member 2 is arranged stationary relative to the base 1, and the nozzle 101 is located on one side of the brush member 2; a holding rod 3 is arranged on the base 1, and the holding rod 3 has a decontamination liquid channel, and the decontamination liquid channel is connected to the nozzle 101.

[0024] In this embodiment, the specific decontamination process of the decontamination device is as follows: The operator holds the handle bar 3 and moves the device to the steel grille that needs to be cleaned, so that the brush part 2 is in close contact with the surface of the steel grille; then the pre-configured cleaning liquid is injected into the nozzle 101 of the substrate 1 at high pressure through the cleaning liquid channel in the handle bar 3, and is sprayed out at a certain pressure and evenly sprinkled on the surface of the steel grille. Specifically, a pipeline can be installed with the cleaning liquid channel, and the pipeline is connected to the reagent preparation box, and is also equipped with a pressure pump and an electric regulating valve to provide the high-pressure power required for the flow of the cleaning liquid and the connectivity of the pipeline. Before each cleaning, the reagent is prepared according to the workshop conditions. Targeted decontamination liquid is configured in the box; finally, as the operator pushes the device, the brush part 2 is kept stationary relative to the base 1, and slides along the surface of the steel grating along with the base 1, and the bristles of the brush penetrate into the gaps of the steel grating to completely brush off the solid suspended matter, garbage fragments, etc. that have been treated with the decontamination liquid and other loosely attached solids from the surface of the steel grating. At the same time, the decontamination liquid infiltrates and dissolves the pollutants, especially for grease pollutants, which can effectively reduce their viscosity and make it easier to detach from the surface of the steel grating, realizing scraping and flushing at the same time, and is equipped with corresponding decontamination liquid to achieve the purpose of efficient cleaning.

[0025] At the same time, when the nozzle 101 located on one side of the brush member 2 sprays out high-pressure decontamination liquid, the high-pressure decontamination liquid not only acts on the surface of the steel grille, but also acts on the brush member 2 to wash away the pollutants adhered to the brush member 2, thereby increasing the cleaning time. Specifically, a plurality of high-pressure nozzles 101 can be arranged in a circle around a group of brush members 2, or the brush members 2 and the high-pressure nozzles 101 can be arranged alternately in a linear manner, or the brush members 2 and the high-pressure nozzles 101 can be arranged in a matrix to further improve the cleaning effect.

[0026] With regard to the specific structure of the overall decontamination device, the base 1 can be made of high-strength plastic material with good friction and light texture, which is convenient for operators to use. The shape can be a rectangular plate structure, and the nozzles 101 are evenly distributed on one long side of the plate-like base 1, and the nozzles 101 are designed to be flat-mouthed, so that the decontamination liquid can be sprayed in a fan shape to cover a wider area. The plate body has moderate thickness, which can ensure structural strength without being too heavy to affect operational convenience; the bristles of the brush member 2 are made of high-strength, wear-resistant nylon, and the length is reasonably designed according to the depth of the steel grille gap, generally slightly longer than the gap depth, to ensure that it can penetrate deep into the bottom of the gap for cleaning, and at the same time the brush member 2 can be fixed to the base 1 by welding or bolting to ensure that it is stable relative to the base 1 without shaking during use; the handle rod 3 is similarly made of high-strength plastic material, and the decontamination liquid channel can be a circular channel, which is built into the center of the handle rod 3, and the inner wall of the channel is smooth to reduce the flow resistance of the decontamination liquid, and one end of the handle rod 3 is rotatably connected to the base 1, which is convenient for the operator to adjust the angle, and the other end is designed into an ergonomic handle shape with anti-slip texture on the surface to prevent it from slipping out of the hand.

[0027] Furthermore, the holding rod 3 is a telescopic holding rod 3, the holding rod 3 has a telescopic end 301, and also includes an angle adjustment member 4. The holding rod 3 is set on the base 1 through the angle adjustment member 4, and the angle adjustment member 4 includes: a connecting member 401 swingingly set on the base 1; two limiting members 402 are spaced apart on the telescopic end 301, the connecting member 401 is located between the two limiting members 402, and is rotatably connected to the two limiting members 402.

[0028] In this embodiment, the entire dirt removal device is similar to a "mop", so in order to add an angle adjustment part 4 to connect the base 1 and the telescopic end 301 of the telescopic handle rod 3, the angle range of the handle rod 3 to drive the base 1 to move is increased to ensure that under the same action, the base 1 can drive the brush part 2 to cover a larger range of the steel grille for cleaning.

[0029] Specifically, the angle adjustment member 4 is composed of a connecting member 401 and two limiting members 402. With the connecting line between the connecting member 401 and the base 1 as the axis, the base 1 can swing within a certain angle range. Two supports can be symmetrically integrally formed on the base 1, and the two ends of the swing axis of the connecting member 401 are respectively rotatably connected to the two supports. Further, the connecting member 401 can be similar to a T-shape, so that the two sides of its middle position are respectively rotatably connected to the two limiting members 402, so that the base 1 can swing within a certain angle and can also swing with the axial direction of the rotating connection as the axis. By ensuring that the two sets of swing axes are cross-arranged, the purpose of increasing the moving angle range of the base 1 can be achieved.

[0030] At the same time, the use of the telescopic handle bar 3 can easily adjust the length of the handle bar 3 according to actual operation requirements. When cleaning steel grilles at a long distance or a deep position, the handle bar 3 is extended to avoid the operator from overstretching the body or using other auxiliary tools, further reducing labor intensity and expanding the operating range of the device.

[0031] Considering further, it is precisely because of the addition of the angle adjustment part 4 that the cleaning range is increased and the movement of the operator is reduced, the spray direction of the high-pressure nozzle 101 of the base 1 can be adjusted at will to achieve multi-directional angle adjustment. In this way, whether facing a flat steel grid or a special steel grid structure with a certain slope or curvature, the brush part 2 and the nozzle 101 can fit closely to the surface of the steel grid, ensuring the best cleaning effect, which greatly improves the adaptability of the device to different working conditions.

[0032] Furthermore, the base 1 is in the shape of an elongated strip, and further comprises: a connecting member 401 rotatably connected to two limit members 402 via a rotating shaft 5, the swing axis of the connecting member 401 and the length direction of the holding rod 3 are both perpendicular to the axis of the rotating shaft 5, and the swing axis of the connecting member 401 is parallel to the length direction of the base 1.

[0033] In this embodiment, the base 1 is in the shape of an elongated strip, and is provided with a rotating shaft 5 which passes through the connecting member 401 and is rotatably connected to two limiting members 402, and each direction is specifically limited. In order to maximize the angle adjustment range of the base 1, the swing axis of the connecting member 401 and the length direction of the holding rod 3 are both perpendicular to the axis of the rotating shaft 5, and the swing axis of the connecting member 401 is parallel to the length direction of the base 1.

[0034] Furthermore, the base 1 has a cavity 102 and a strip groove 103 . The strip groove 103 has a plurality of nozzles 101 . The plurality of nozzles 101 are connected to the decontamination liquid channel through the cavity 102 . The brush member 2 is located in the strip groove 103 , and the brush member 2 is exposed from the strip groove 103 .

[0035] In this embodiment, the base body 1 is provided with a cavity 102 as a transfer storage space for the decontamination liquid, so that the liquid flowing into the decontamination liquid channel of the holding rod 3 can be evenly dispersed in the cavity 102 first, and then sprayed out through a plurality of nozzles 101 on the strip groove 103 connected to the cavity 102, ensuring the uniform high-pressure spraying of the decontamination liquid on the surface of the steel grating, avoiding the situation of excessive or insufficient local spraying. In order to further realize the connection of the liquid path and improve the above advantages, a plurality of branch pipes can be arranged in the cavity 102, and the decontamination liquid channel is connected with a plurality of nozzles 101 through a pipe opening. Moreover, since the telescopic end 301 of the holding rod 3 of the decontamination liquid channel is connected to the base body 1 through the angle adjustment member 4, Figure 2 As shown, a pipeline can be further installed to connect the two ends of the pipeline to the decontamination liquid channel and the cavity 102 or the branch pipe of the cavity 102 respectively.

[0036] On the one hand, the strip groove 103 provides a suitable arrangement position for a plurality of nozzles 101, and on the other hand, it also provides an arrangement position for the brush member 2, so as to realize alternating arrangement in a linear sequence. For example, if the strip groove 103 is arranged with 10 groups of nozzles 101, 5 brush members 2 are configured to be interference fit in the strip groove 103 at intervals, and the brush member 2 blocks certain nozzles 101 correspondingly, so as to facilitate disassembly and position adjustment while ensuring the scraping and washing function. Some nozzles 101 spray directly onto the steel grille, and some nozzles 101 spray directly onto the brush member 2 to clean the brush while also cleaning the steel grille.

[0037] Interference fit is only one form of position adjustment for the brush member 2. It can also be achieved by using elastic protrusions or bolts. The position adjustment is to adapt to the specifications and sizes of different steel gratings to ensure the cleaning quality. In order to ensure that the brush member 2 can brush the steel grating, it is still necessary to ensure that it is exposed in the strip groove 103. The brush member 2 and the nozzle 101 are cleverly integrated in the strip groove 103, making the structure of the entire decontamination device more compact and simple.

[0038] Furthermore, the strip groove 103 is arranged along the length direction of the base 1, and also includes: a floating plate 6 is arranged in the strip groove 103 and is movable along the depth direction of the strip groove 103, the floating plate 6 has a plurality of connecting ports 601, and the connecting ports 601 correspond to the nozzles 101 one by one; an elastic member 7, the two ends of the elastic member 7 are respectively connected to the floating plate 6 and the base 1, the elastic member 7 provides a force for the floating plate 6 to approach the base 1, and the brush member 2 is detachably arranged on the floating plate 6.

[0039] In this embodiment, when the device contacts steel grilles of different flatness, or when the brush member 2 passes through baffles between different grids of the steel grille, the floating plate 6 can flexibly move along the depth direction of the strip groove 103 under the action of the elastic member 7, that is, it is lifted up and the spring is compressed to make some space for the brush member 2 to avoid jamming during the moving cleaning process, so that the brush member 2 always fits tightly to the steel grille to ensure that the cleaning effect is not affected.

[0040] Specifically, in order to prevent the floating plate 6 from blocking the nozzle 101, a plurality of communication ports 601 corresponding to the nozzle 101 are further provided on the floating plate 6, so that the liquid spraying will not be deflected or blocked due to the movement of the floating plate 6. The brush member 2 is detachably arranged on the floating plate 6, which greatly facilitates subsequent maintenance. When the brush is severely worn or needs to be replaced with different brushes according to different steel grating cleaning requirements or size specifications, the operator does not need complicated tools or disassemble the entire device. It can be quickly replaced with simple operations. The form can be interference fit, elastic protrusion or bolt, etc.

[0041] Furthermore, the base body 1 has a contact surface 104 , and the contact surface 104 is located at the top of the strip groove 103 .

[0042] In this embodiment, an abutment surface 104 is designed to be disposed at the top of the strip groove 103 , so that when cleaning, the device can be quickly aligned with the surface of the steel grille for stable moving cleaning without blocking the brush member 2 protruding from the strip groove 103 .

[0043] Furthermore, there are a plurality of brush members 2, and the positions of the brush members 2 are adjustable on the floating plate 6. The brush members 2 are arranged at intervals along the length direction of the base 1, and the brush members 2 and the connecting openings 601 are alternately arranged in sequence.

[0044] In this embodiment, Figure 3-6 , is an implementation of the brush member 2, that is, a plurality of brush members 2 are arranged at adjustable intervals along the length direction of the strip groove 103, and are alternately arranged with the connecting port 601 in sequence to fully cover the entire base 1 and improve the cleaning ability.

[0045] Furthermore, the brush member 2 comprises: a roller body 8 rotatably disposed on the floating plate 6; and a plurality of brush rings 9, which are all sleeved on the roller body 8 and whose positions relative to the roller body 8 are adjustable.

[0046] In this embodiment, Figure 7-11 , is another implementation mode of the brush member 2, namely, a roller form, so that during the mobile cleaning process, the roller rotates to increase the contact frequency between the brush member 2 and the steel grille, thereby improving the cleaning effect. Specifically, it is composed of a roller body 8 and a plurality of brush rings 9 which are sleeved thereon and have adjustable relative positions. The adjustable positions can adapt to different working scenes, and during normal cleaning, the roller body 8 will drive the brush rings 9 to rotate; the plurality of brush rings 9 are arranged at intervals to correspond to the connecting port 601, so as to give play to the joint effect of the brush rings 9 and the connecting port 601.

[0047] Furthermore, the roller body 8 has a plurality of impeller segments 801 arranged in sequence, and the impeller segments 801 correspond to the connecting ports 601 one by one. The brush ring 9 is sleeved on the impeller segment 801. The impeller segment 801 has a plurality of force grooves 802, and the plurality of force grooves 802 are arranged along the circumference of the impeller segment 801. The force grooves 802 are configured to be subjected to the external force of the water flow from the connecting port 601, thereby driving the plurality of brush rings 9 to rotate.

[0048] Furthermore, the cross section of the stress-bearing groove 802 is fan-shaped, and the central angle of the cross section of the stress-bearing groove 802 is an acute angle.

[0049] In this embodiment, an external motor may be configured to control the rotation of the roller body 8. However, the external motor of the dirt removal device will increase the cost on the one hand, and will be more difficult for operators to operate on the other hand. Therefore, the water flow power of the high-pressure nozzle 101 is used to drive the roller body 8 to rotate. In this way, the cleaning can be carried out synchronously with the rotation of the roller body 8, and the cleaning action is more precise and the quality is also smaller.

[0050] Specifically, the roller body 8 is divided into a number of impeller segments 801 which are connected in sequence, connected by welding or fasteners, and in fact, a number of circumferentially arranged force grooves 802 are provided, and the cross-section of the force groove 802 is preferably fan-shaped, and the central angle of the cross-section of the force groove 802 is an acute angle. Furthermore, since the impeller segment 801 corresponds to the connecting port 601 one by one, a part of the high-pressure water flow passing through the nozzle 101 and the connecting port 601 acts on the inner wall of the force groove 802, driving the roller body 8 to rotate as a whole, and another part of the high-pressure water flow passing through the nozzle 101 and the connecting port 601 acts on the brush ring 9 to clean the brush ring 9; the position adjustment form of the brush ring 9 can be an interference fit or an elastic protrusion, and it can slide along the axial direction of the roller body 8 to the corresponding position of the connecting port 601.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
