Description

Technical Field

[0001] The present application relates to the technical field of environmental sanitation equipment, and in particular, to a pure electric dust suppression vehicle. Background Art

[0002] A pure electric dust suppression vehicle is an important engineering vehicle for reducing the content of PM2.5 in the urban air. It can suppress dust pollution by spraying a dust suppression curing agent to purify the urban environment. At the same time, the pure electric dust suppression vehicle uses electric clean energy and will not increase exhaust pollution during the dust suppression process.

[0003] Existing pure electric dust suppression vehicles include a fog cannon barrel, a fan, a spraying mechanism, and an adjusting mechanism. For example, a pure electric multi-functional dust suppression vehicle disclosed in a Chinese patent with the publication number CN108580083A, and a spraying dust suppression device and a dust suppression vehicle disclosed in a Chinese patent with the publication number CN216677516U. The fog cannon barrel is connected to the adjusting mechanism, and the fan and the spraying mechanism are arranged on the fog cannon barrel. The orientation of the fog cannon barrel can be adjusted through the adjusting mechanism. With the assistance of the wind force of the fan, the spraying mechanism can spray the dust suppression curing agent far into the air to achieve the effect of accurate dust suppression.

[0004] The spraying range of the spraying mechanism in the above solution is always limited within the barrel opening range of the fog cannon barrel. When large-scale dust occurs in the city, such as during a sandstorm, although the adjusting mechanism can drive the fog cannon barrel to swing to expand the spraying area, due to the limitation of the spraying range, the dust suppression efficiency of the dust suppression vehicle is low, and it often takes the dust suppression vehicle to stay in place for a long time to effectively suppress the large-scale dust in the area where the dust suppression vehicle is located. Summary of the Invention

[0005] In order to enable the dust suppression vehicle to simultaneously have the effects of long-distance accurate dust suppression and large-area high-efficiency dust suppression, the present application provides a pure electric dust suppression vehicle.

A connecting frame is connected to the end of the transmission rod away from the driving part. The connecting frame is hinged to the ends of the multiple flow guiding plates corresponding to the adjustable liquid pipes close to the fan. When the driving part drives the first inner ring liquid pipe and the first outer ring liquid pipe to rotate towards the outside of the fog cannon barrel, the guiding part is used to make the flow guiding plates driven by the transmission rod incline away from the flow dividing plates.

[0013] Optionally, the guiding part includes a guiding plate and a sliding seat.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. A pure electric dust suppression vehicle of the present application includes a vehicle body, a fog cannon barrel, a central liquid pipe, a fixed liquid pipe, an adjustable liquid pipe, a switching nozzle, a liquid pipe adjusting assembly, and a nozzle switching assembly. Among them, when long-distance accurate dust suppression is required, the first inner ring liquid pipe and the first outer ring liquid pipe are located at the barrel mouth of the fog cannon barrel. Under the elastic force of the switching spring, the switching nozzle can be in a direct spraying state.

At the same time, the first push rod can push the transmission pulling rope corresponding to the first inner ring liquid pipe to move, and the second push rod can push the transmission pulling rope corresponding to the first outer ring liquid pipe to move, so that the switching nozzle is switched from the direct spraying state to the scattered spraying state to expand the spraying area of the switching nozzle, thereby expanding the spraying range of the dust suppression vehicle, making the spraying range of the dust suppression vehicle not easily limited to the range of the barrel mouth of the fog cannon barrel, so that the dust suppression vehicle can achieve large-area and high-efficiency dust suppression. Furthermore, by adjusting the positions of the first inner ring liquid pipe and the first outer ring liquid pipe, the dust suppression vehicle can simultaneously have the effects of long-distance accurate dust suppression and large-area and high-efficiency dust suppression; 2. A pure electric dust suppression vehicle of the present application further includes a guiding assembly. Among them, when the transmission rod drives the first push rod and the second push rod to move, the transmission rod can also drive the guiding plate to move. With the assistance of the guiding plate and the sliding seat, the guiding plate can be tilted. The tilted guiding plate can make the wind force between the flow dividing plate and the inner wall of the fog cannon barrel blow towards the scattered spraying dust suppression curing agent, so that the scattered spraying dust suppression curing agent can also be blown by the wind force.

Detailed Description of the Embodiment

[0019] The following will further describe the present application in detail with reference to the attached Figures 1-6 drawings.

[0020] An embodiment of the present application discloses a pure electric dust suppression vehicle. Referring to Figure 1 and Figure 2 , a pure electric dust suppression vehicle includes a vehicle body 1, a fog cannon barrel 2, a central liquid pipe 3, a fixed liquid pipe 4, and an adjustable liquid pipe 5.

[0021] Referring to Figure 1 and Figure 3, the fog cannon barrel 2 is arranged on the vehicle body 1, and a blower 21 is arranged at one end. The blower 21 is used to provide the wind force for blowing the dust suppression and solidification agent.

[0022] Refer to Figure 2 and Figure 3 , the central liquid pipe 3 is arranged in the fog cannon barrel 2. A plurality of support plates 31 are fixedly connected between the outer wall of the central liquid pipe 3 and the inner wall of the fog cannon barrel 2. All the support plates 31 support the central liquid pipe 3 at the central position of the fog cannon barrel 2.

[0023] The fixed liquid pipe 4 is arranged on the bottom edge of the fog cannon barrel 2 at the end far from the blower 21. The fixed liquid pipe 4 is arranged to fit the edge of the fog cannon barrel 2. The fixed liquid pipe 4 is fixedly connected with a fixed support 41, and the fixed support 41 is fixedly connected to the fog cannon barrel 2.

[0024] There are two adjustable liquid pipes 5, and the two adjustable liquid pipes 5 are symmetrically arranged on the edge of the fog cannon barrel 2 at the end far from the blower 21. The adjustable liquid pipes 5 are arranged to fit the edge of the fog cannon barrel 2. The two adjustable liquid pipes 5 are respectively located at both ends of the fixed liquid pipe 4.

[0025] Refer to Figure 2 , the adjustable liquid pipe 5 includes a first inner ring liquid pipe 51 and a first outer ring liquid pipe 52. The first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are arranged in the direction away from the center of the fog cannon barrel 2. The first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are jointly connected with an adjustment bracket 53, and the adjustment bracket 53 is fixedly connected to the fog cannon barrel 2. The middle parts of the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are both rotatably connected to the adjustment bracket 53, so that the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 can rotate away from the barrel mouth area of the fog cannon barrel 2.

[0026] Among them, the middle parts of the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are both straightly arranged, so that both the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are convenient for rotating relative to the adjustment bracket 53. At the same time, two rotating pieces 54 are fixedly connected to the middle parts of the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 respectively. The two rotating pieces 54 are respectively attached to both sides of the adjustment bracket 53, so that the rotation of the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 relative to the adjustment bracket 53 is more stable.

[0027] The central liquid pipe 3, the fixed liquid pipe 4, the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are all connected to a liquid supply pipe 32 for introducing the dust suppression and solidification agent. A plurality of direct spray nozzles 33 are connected to both the central liquid pipe 3 and the fixed liquid pipe 4, and the direct spray nozzles 33 are used for directly spraying the dust suppression and solidification agent. A plurality of switching nozzles 6 are provided on both the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52, and the switching nozzles 6 have two spraying states. The first spraying state of the switching nozzle 6 is direct spraying, which can directly eject the dust suppression and solidification agent to achieve long-distance and accurate dust reduction. The second spraying state of the switching nozzle 6 is scattered spraying, which can scatter the dust suppression and solidification agent to achieve large-area and efficient dust reduction.

[0028] Referring to Figure 3 and Figure 4 , each adjustable liquid pipe 5 is connected to a liquid pipe adjustment component 7. The liquid pipe adjustment component 7 includes a driving member 71, a first push rod 72, a second push rod 73, a first swing rod 74 and a second swing rod 75. The driving member 71 is fixedly connected to the inner wall of the fog cannon barrel 2 and is connected to both the first push rod 72 and the second push rod 73. The first push rod 72 and the second push rod 73 can move along the axis direction of the fog cannon barrel 2 under the drive of the driving member 71.

[0029] Among them, referring to Figure 3 , the driving member 71 is a power element capable of outputting linear power, such as an electric push rod, a cylinder or a hydraulic cylinder.

[0030] Referring to Figure 3 and Figure 4 , one end of the first push rod 72 away from the driving member 71 is slidably connected to one end of the first swing rod 74, the other end of the first swing rod 74 is fixedly connected to the middle part of the first inner ring liquid pipe 51, one end of the second push rod 73 away from the driving member 71 is slidably connected to one end of the second swing rod 75, the other end of the second swing rod 75 is fixedly connected to the middle part of the first outer ring liquid pipe 52, and the angle of swing of the second swing rod 75 driven by the second push rod 73 is twice the angle of swing of the first swing rod 74 driven by the first push rod 72, so that the rotation angle of the first outer ring liquid pipe 52 is twice the rotation angle of the first inner ring liquid pipe 51, thereby not only expanding the spraying area but also reducing the overlapping area of the spraying.

[0031] Referring to Figure 3 and Figure 5 , a nozzle switching component 8 is provided on each first inner ring liquid pipe 51 and each first outer ring liquid pipe 52. The nozzle switching component 8 is used to switch the two spraying states of all the switching nozzles 6 on the first inner ring liquid pipe 51 or the first outer ring liquid pipe 52. When the driving member 71 drives the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 to rotate towards the outside of the fog cannon barrel 2, the spraying state of the switching nozzle 6 is switched from direct spraying to scattered spraying.

[0032] During use, when long-distance and precise dust suppression is required, the positions of the first inner liquid pipe 51 and the second outer liquid pipe 43 are kept at the mouth of the fog cannon barrel 2. At this time, the switching nozzle 6 is in the direct spraying state, and the dust suppression curing agent is supplied through the liquid supply pipe 32, so that the direct nozzles 33 on the central liquid pipe 3 and the fixed liquid pipe 4 and the switching nozzles 6 on the first inner liquid pipe 51 and the first outer liquid pipe 52 can jointly spray the dust suppression curing agent directly. The fan 21 provides wind power to the sprayed dust suppression curing agent, so that the directly sprayed dust suppression curing agent can be sprayed far away under the push of the wind power for long-distance and precise dust suppression.

[0033] When large-area and efficient dust suppression is required, the driving member 71 is used to drive the first push rod 72 and the second push rod 73 to move. The first push rod 72 drives the first swing rod 74 to swing, so that the first swing rod 74 drives the first inner liquid pipe 51 to rotate outward toward the fog cannon barrel 2. The second push rod 73 drives the second swing rod 75 to swing, so that the second swing rod 75 drives the first outer liquid pipe 52 to rotate outward toward the fog cannon barrel 2. Since under the same moving stroke, the swing angle of the second swing rod 75 driven by the second push rod 73 is twice the swing angle of the first swing rod 74 driven by the first push rod 72, the rotation angle of the first outer liquid pipe 52 is twice the rotation angle of the first inner liquid pipe 51. Since the rotation angles of the first outer liquid pipe 52 and the first inner liquid pipe 51 are inconsistent, the spraying directions of the switching nozzles 6 on the first outer liquid pipe 52 and the switching nozzles 6 on the first inner liquid pipe 51 are inconsistent. And since the rotation angle of the first outer liquid pipe 52 is twice the rotation angle of the first inner liquid pipe 51, the spraying area of the switching nozzles 6 on the first inner liquid pipe 51 can just be between the spraying area of the switching nozzles 6 on the first outer liquid pipe 52 and the spraying area of the direct nozzles 33 on the central liquid pipe 3, thereby expanding the spraying area of the dust suppression curing agent and reducing the overlapping spraying area.

[0034] When the first inner liquid pipe 51 and the first outer liquid pipe 52 turn outward toward the fog cannon barrel 2, the spraying state of the switching nozzles 6 can be switched from direct spraying to scattered spraying under the action of the nozzle switching assembly 8, increasing the spraying area of a single switching nozzle 6. Thus, by expanding the spraying area and the spraying area, the spraying range of the dust suppression vehicle is expanded, so that the spraying range of the dust suppression vehicle is not easily limited to the range of the mouth of the fog cannon barrel 2. With the joint cooperation of the central liquid pipe 3, the fixed liquid pipe 4, and the rotated first inner liquid pipe 51 and the first outer liquid pipe 52, the dust suppression vehicle can achieve large-area and efficient dust suppression, and further enables the dust suppression vehicle to simultaneously have the effects of long-distance and precise dust suppression and large-area and efficient dust suppression.

[0035] Among them, referring to Figure 2, the fixing liquid pipe 4 includes a second inner ring liquid pipe 42 and a second outer ring liquid pipe 43. The second inner ring liquid pipe 42 and the second outer ring liquid pipe 43 are arranged in a direction away from the center of the fog cannon barrel 2. Both the second inner ring liquid pipe 42 and the second outer ring liquid pipe 43 are fixedly connected to the fixing bracket 41. When performing long-distance precise dust suppression, the two first inner ring liquid pipes 51 and the second inner ring liquid pipe 42 can be combined into a spraying ring, and the two first outer ring liquid pipes 52 and the second outer ring liquid pipe 43 can also be combined into a spraying ring. Thus, the two nested spraying rings increase the spraying amount of the dust suppression curing agent and improve the dust suppression effect.

[0036] Specifically, referring to Figure 4 , the sliding connection structure between the first push rod 72 and the first swing rod 74 is the same as the sliding connection structure between the second push rod 73 and the second swing rod 75. An adjusting slide rod 722 is connected to the first push rod 72. The adjusting slide rod 722 is slidably arranged in a kidney-shaped hole 741 opened on the first swing rod 74. When the first push rod 72 moves, the adjusting slide rod 722 can slide in the kidney-shaped hole 741, and the adjusting slide rod 722 can drive the first swing rod 74 to swing during the sliding process.

[0037] Specifically, referring to Figure 6 , the switching nozzle 6 includes a nozzle pipe 61, a switching housing 62, a spraying housing 63 and a switching part 64.

[0038] Referring to Figure 5 and Figure 6 , one end of the nozzle pipe 61 is connected to the first inner ring liquid pipe 51 or the first outer ring liquid pipe 52. The switching housing 62 is integrally formed and connected to the other end of the nozzle pipe 61. A plurality of switching holes 621 are opened on the switching housing 62. The spraying housing 63 is slidably sleeved on the other end of the nozzle pipe 61. A plurality of scattered spraying holes 631 are opened on the spraying housing 63, and a straight spraying pipe 632 is fixedly penetrated. The straight spraying pipe 632 is slidably penetrated through the switching housing 62. When the dust suppression curing agent is sprayed out from the straight spraying pipe 632, the dust suppression curing agent can be directly sprayed. When the dust suppression curing agent is sprayed out from the scattered spraying holes 631, the dust suppression curing agent can be scattered and sprayed.

[0039] Referring to Figure 6 , when the straight spraying pipe 632 slides out of the nozzle pipe 61, the switching part 64 is used to close the switching holes 621 and conduct the straight spraying pipe 632, so that the nozzle pipe 61 is communicated with the straight spraying pipe 632. When the straight spraying pipe 632 slides into the nozzle pipe 61, the switching part 64 is used to close the straight spraying pipe 632 and conduct the switching holes 621, so that the nozzle pipe 61 is communicated with the spraying housing 63 through the switching holes 621.

[0040] When direct spraying is required, slide the spray housing 63 so that the direct spray pipe 632 slides out of the spray pipe 61. At this time, the switching part 64 can close the switching hole 621 to prevent the dust suppressant curing agent in the spray pipe 61 from flowing into the space between the spray housing 63 and the direct spray pipe 632, and the switching part 64 can conduct the direct spray pipe 632 so that the dust suppressant curing agent can be ejected from the direct spray pipe 632. When scattered spraying is required, slide the spray housing 63 in the reverse direction so that the direct spray pipe 632 slides into the spray pipe 61. At this time, the switching part 64 closes the direct spray pipe 632 to prevent the dust suppressant curing agent in the spray pipe 61 from flowing into the direct spray pipe 632, and the switching part 64 can conduct the switching hole 621 so that the dust suppressant curing agent can flow into the space between the spray housing 63 and the direct spray pipe 632 and be ejected from the scattered spray holes 631. Thus, by sliding the spray housing 63, the spraying state of the switching nozzle 6 can be switched.

[0041] Further, referring to Figure 6 , the switching part 64 includes a switching pipe 641, a direct spray closing piece 642, and a scattered spray closing piece 643.

[0042] The switching pipe 641 is located in the spray pipe 61 and sleeved on the direct spray pipe 632. The switching pipe 641 is integrally formed and connected with the switching housing 62. The end of the switching pipe 641 away from the switching housing 62 is in a constricted shape. A plurality of direct spray closing pieces 642 are provided and are elastically connected to one end of the direct spray pipe 632 close to the constricted end of the switching pipe 641 in the axial direction of the direct spray pipe 632. The direct spray closing pieces 642 can fit on the inner wall of the switching pipe 641 under the elastic action. The constricted end of the switching pipe 641 can gather all the direct spray closing pieces 642 to close the direct spray pipe 632. One end of the scattered spray closing piece 643 is fixedly connected to the outer wall of the direct spray pipe 632 and is slidably arranged in the switching slide hole 6411 opened on the switching pipe 641. When the direct spray closing pieces 642 fit on the switching pipe 641, the scattered spray closing piece 643 closes the switching hole 621. When the direct spray closing pieces 642 are gathered, the scattered spray closing piece 643 opens the switching hole 621.

[0043] Among them, the direct spray closing piece 642 is integrally formed and connected to the direct spray pipe 632, and the connection part between the direct spray closing piece 642 and the direct spray pipe 632 has elasticity.

[0044] The position of the direct injection pipe 632 relative to the switching pipe 641 can be adjusted by sliding the injection shell 63. Since the end of the switching pipe 641 is constricted, when the direct injection pipe 632 drives the direct injection closing piece 642 to slide into the injection pipe 61, all the direct injection closing pieces 642 will gather together under the guiding action of the constricted end of the switching pipe 641. The gathered direct injection closing pieces 642 can close the direct injection pipe 632. Since the spray closing piece 643 is fixedly connected to the direct injection pipe 632, the spray closing piece 643 will move with the direct injection pipe 632 to open the switching hole 621, so that the direct injection pipe 632 can be closed and the switching hole 621 can be conducted.

[0045] When the direct injection pipe 632 slides out of the injection pipe 61, the direct injection pipe 632 can drive the direct injection closing piece 642 away from the constricted end of the switching pipe 641. Under the elastic force at the connection between the direct injection closing piece 642 and the direct injection pipe 632, the direct injection closing piece 642 can fit on the inner wall of the switching pipe 641, so that all the direct injection closing pieces 642 are in a dispersed state. The dispersed direct injection closing pieces 642 can open the direct injection pipe 632. At the same time, the spray closing piece 643 will move with the direct injection pipe 632 to close the switching hole 621, so that the direct injection pipe 632 can be opened and the switching hole 621 can be closed.

[0046] Specifically, referring to Figure 6 , the nozzle switching assembly 8 includes a switching spring 81, a switching pull rope 82, a first guide ring 83 and a transmission pull rope 84.

[0047] There are multiple groups of switching springs 81, which are correspondingly arranged between the injection shell 63 and the injection pipe 61. Each group of switching springs 81 has multiple springs, and the multiple switching springs 81 are arranged around the axis of the injection pipe 61. One end of the switching spring 81 is fixedly connected to the injection shell 63, and the other end is fixedly connected to the injection pipe 61. The switching spring 81 is used to drive the direct injection pipe 632 to slide out of the injection pipe 61.

[0048] Referring to Figure 5 and Figure 6 , there are multiple switching pull ropes 82. One end of each switching pull rope 82 is fixedly connected to the injection shell 63 correspondingly. There are multiple first guide rings 83, which are fixedly connected to the injection pipe 61 correspondingly. The end of the switching pull rope 82 far from the injection shell 63 slides through the first guide ring 83. Under the guiding action of the first guide ring 83, no matter which direction the switching pull rope 82 is pulled, it can drive the direct injection pipe 632 to slide into the injection pipe 61. The transmission pull rope 84 is fixedly connected to the ends of all the switching pull ropes 82 far from the injection shell 63. Pulling the transmission pull rope 84 can drive all the switching pull ropes 82 to move simultaneously.

[0049] Under the elastic force of the switching spring 81, the injection shell 63 can keep the direct injection pipe 632 in a conducting state and the switching hole 621 in a closed state, so that the switching nozzle 6 can be in a direct spraying state; when the transmission pull rope 84 is pulled, the transmission pull rope 84 can pull all the switching pull ropes 82 connected to itself to move. Under the guiding action of the first guiding ring 83, the switching pull rope 82 can pull the injection shell 63 to slide, so that the direct injection pipe 632 slides into the spray pipe 61, the direct injection pipe 632 can be kept in a closed state, and the switching hole 621 can be in a conducting state, so that the switching nozzle 6 can be in a scattering spraying state, thereby facilitating the synchronous switching of the spraying states of all the switching nozzles 6 on the first inner ring liquid pipe 51 or the first outer ring liquid pipe 52.

[0050] Further, referring to Figure 4 and Figure 5 , in order to make the switching timing of the switching nozzle 6 be stably synchronized with the rotation timing of the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52, the nozzle switching assembly 8 further includes a second guiding ring 85. There are four second guiding rings 85, and the four second guiding rings 85 are arranged in a matrix on the adjusting bracket 53. The second guiding ring 85 is fixedly connected to the adjusting bracket 53, and the middle part of the transmission pull rope 84 passes through the four second guiding rings 85 one by one.

[0051] Referring to Figure 4 , clamping grooves 721 are formed at the ends of the first push rod 72 and the second push rod 73 away from the driving member 71. The middle position of the transmission pull rope 84 corresponding to the first inner ring liquid pipe 51 is located on the moving path of the clamping groove 721 on the first push rod 72. The clamping groove 721 of the first push rod 72 is used to clamp the transmission pull rope 84 corresponding to the first inner ring liquid pipe 51 when the first push rod 72 moves, so as to push the transmission pull rope 84 to move. The middle position of the transmission pull rope 84 corresponding to the first outer ring liquid pipe 52 is located on the moving path of the clamping groove 721 on the second push rod 73. The clamping groove 721 of the second push rod 73 is used to clamp the transmission pull rope 84 corresponding to the first outer ring liquid pipe 52 when the second push rod 73 moves, so as to push the transmission pull rope 84 to move.

[0052] When the first push rod 72 and the second push rod 73 move, the first push rod 72 can clamp the transmission pull rope 84 corresponding to the first inner ring liquid pipe 51 into the clamping groove 721 on itself. The first push rod 72 can stably push the transmission pull rope 84 corresponding to the first inner ring liquid pipe 51 to move through the clamping groove 721, so that the transmission pull rope 84 can drive all the switching pull ropes 82 corresponding to the first inner ring liquid pipe 51 to move, so that all the switching nozzles 6 corresponding to the first inner ring liquid pipe 51 can synchronously switch their states.

[0053] The second push rod 73 can clamp the transmission cable 84 corresponding to the first outer liquid pipe 52 into the clamping groove 721 on itself. The second push rod 73 can stably push the transmission cable 84 corresponding to the first outer liquid pipe 52 to move through the clamping groove 721, so that the transmission cable 84 can drive all the switching cables 82 corresponding to the first outer liquid pipe 52 to move, enabling all the switching nozzles 6 corresponding to the first outer liquid pipe 52 to synchronously switch states, so that the switching timing of the switching nozzles 6 can be stably synchronized with the rotation timing of the first inner liquid pipe 51 and the first outer liquid pipe 52.

[0054] Refer to Figure 3 and Figure 4 In order to enable the driving member 71 to synchronously drive the first push rod 72 and the second push rod 73, the driving member 71 is connected with a transmission rod 711. The ends of the first push rod 72 and the second push rod 73 are both fixedly connected to the side wall of the transmission rod 711. The driving member 71 can simultaneously provide driving forces to the first push rod 72 and the second push rod 73 through the transmission rod 711.

[0055] Refer to Figure 3 and Figure 5 In order to enable the dust suppression and solidification agent sprayed after the rotation of the first inner liquid pipe 51 and the first outer liquid pipe 52 to be blown by the wind force of the fan 21, a diversion assembly 9 is arranged on the support plate 31. The diversion assembly 9 includes a diversion plate 91, a guide plate 92 and a guiding part 93.

[0056] A plurality of diversion plates 91 are provided and are fixedly connected between adjacent two support plates 31 one by one. A plurality of guide plates 92 and guiding parts 93 are provided and are in one-to-one correspondence. The plurality of guide plates 92 correspond to the plurality of diversion plates 91 corresponding to the adjustable liquid pipe 5 one by one. The guiding part 93 is connected to the end of the diversion plate 91 far away from the fan 21 and is connected to the guide plate 92.

[0057] A connecting frame 712 is fixedly connected to the end of the transmission rod 711 far away from the driving member 71. The connecting frame 712 is hinged to the ends of the plurality of guide plates 92 corresponding to the adjustable liquid pipe 5 close to the fan 21. When the driving member 71 drives the first inner liquid pipe 51 and the first outer liquid pipe 52 to rotate towards the outside of the fog cannon barrel 2, the guiding part 93 is used to make the guide plate 92 driven by the transmission rod 711 tilt away from the diversion plate 91.

[0058] All the flow dividing plates 91 divide the wind force of the fan 21 into two parts. The first part of the wind force flows within the area enclosed by all the flow dividing plates 91, and the second part of the wind force flows within the area between all the flow dividing plates 91 and the fog cannon barrel 2. When performing long-distance precise dust suppression, the first part of the wind force and the second part of the wind force have the same blowing direction, so that the sprayed dust suppression solidifying agent can be sprayed far away. When performing large-area efficient dust suppression, the transmission rod 711 not only drives the first push rod 72 and the second push rod 73 to move, but also drives the flow guiding plate 92 to move through the connecting frame 712. Under the guiding action of the guiding part 93, the flow guiding plate 92 can tilt away from the flow dividing plate 91 to form a guiding inclined plane. At this time, the blowing direction of the first part of the wind force remains unchanged to blow the dust suppression solidifying agent sprayed by the central liquid pipe 3, and the blowing direction of the second part of the wind force will blow towards the dust suppression solidifying agent scattered and sprayed by the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 under the guiding action of the guiding inclined plane formed by the flow guiding plate 92, so that the dust suppression solidifying agent sprayed by the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 can also be blown by the wind force.

[0059] Further, referring to Figure 5 , the guiding part 93 includes a guiding plate 931 and a sliding seat 932.

[0060] The guiding plate 931 is fixedly connected to the end of the flow dividing plate 91 and is located on the side of the flow dividing plate 91 close to the adjustable liquid pipe 5. The guiding plate 931 is arranged at an angle with the flow dividing plate 91. The sliding seat 932 is hinged to the side of the guiding plate 931 away from the flow dividing plate 91, and the sliding seat 932 is slidably arranged in a flow guiding chute 921 opened on the flow guiding plate 92.

[0061] When the hinged end of the flow guiding plate 92 and the connecting frame 712 gradually approaches the guiding plate 931, the flow guiding plate 92 will be tilted by the driving force transmitted by the guiding plate 931 through the sliding seat 932. Since the sliding seat 932 rotates relative to the guiding plate 931 while sliding on the flow guiding plate 92, the flow guiding plate 92 can always maintain the connection relationship with the guiding plate 931 during the deflection process, and the guiding plate 931 is not likely to hinder the tilting of the flow guiding plate 92.

[0062] Referring to Figure 3 and Figure 5 , after the flow guiding plate 92 is tilted, it is difficult for the dust suppression solidifying agent on the leeward side of the flow guiding plate 92 to be blown by the wind force. In order to enable the dust suppression solidifying agent on the leeward side of the flow guiding plate 92 to also be blown by the wind force, a plurality of ventilation holes 922 are opened on the flow guiding plate 92. The ventilation holes 922 penetrate through the flow guiding plate 92, and the opening direction of the ventilation holes 922 is arranged at an angle with the plate surface of the flow guiding plate 92. When the flow guiding plate 92 is tilted to the maximum angle, the opening direction of the ventilation holes 922 is parallel to the axis direction of the fog cannon barrel 2.

[0063] When the deflector 92 is tilted to the maximum angle, the opening direction of the ventilation hole 922 can be parallel to the axis direction of the fog cannon barrel 2, so that a small part of the wind force in the second part of the wind force can directly pass through the ventilation hole 922. The wind force passing through the ventilation hole 922 can blow the dust suppression curing agent on the leeward side of the deflector 92, so that the dust suppression curing agent on the leeward side of the deflector 92 can also be blown by the wind force.

[0064] The implementation principle of an electric dust suppression vehicle according to an embodiment of the present application is as follows: during use, when the position of the adjustable liquid pipe 5 is maintained at the barrel opening of the fog cannon barrel 2, the switching nozzle 6 is switched to the direct spraying state. The direct spraying nozzles 33 on the central liquid pipe 3 and the fixed liquid pipe 4 and the switching nozzle 6 on the adjustable liquid pipe 5 can all perform direct spraying. With the assistance of wind force, the dust suppression vehicle can perform long-distance and precise dust suppression. When the adjustable liquid pipe 5 turns to the outside of the fog cannon barrel 2 under the drive of the liquid pipe adjustment assembly 7, the spraying direction of the switching nozzle 6 can deviate from the barrel opening area of the fog cannon barrel 2, and under the combined drive of the nozzle switching assembly 8 and the liquid pipe adjustment assembly 7, the spraying state of the switching nozzle 6 is switched from direct spraying to scattering spraying, while expanding the spraying area and also expanding the spraying area, thereby expanding the spraying range of the dust suppression vehicle, enabling the dust suppression vehicle to perform large-area and efficient dust suppression, and further enabling the dust suppression vehicle to simultaneously have the effects of long-distance and precise dust suppression and large-area and efficient dust suppression.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
