Description

Technical Field

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

[0002] Pure electric dust suppression vehicles are important engineering vehicles for reducing the PM2.5 content in urban air. They can suppress dust pollution by spraying dust suppression curing agents to purify the urban environment. At the same time, pure electric dust suppression vehicles use clean electricity as 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, an injection mechanism and an adjustment mechanism. For example, the Chinese patent publication number CN108580083A discloses a pure electric multifunctional dust suppression vehicle, and the Chinese patent publication number CN216677516U discloses a spray dust suppression device and a dust suppression vehicle. The fog cannon barrel is connected to the adjustment mechanism, and the fan and the injection mechanism are arranged on the fog cannon barrel. The direction of the fog cannon barrel can be adjusted through the adjustment mechanism. With the assistance of the wind force of the fan, the injection mechanism can spray the dust suppression curing agent into the air at a long distance to achieve the effect of precise dust reduction.

[0004] The spraying range of the injection mechanism in the above scheme is always limited to the muzzle range of the fog cannon. When large-scale dust occurs in the city, such as sandstorms, although the adjustment mechanism can drive the fog cannon to swing to expand the spraying area, the limitation of the spraying range will lead to low dust reduction efficiency of the dust suppression vehicle. It is often necessary for the dust suppression vehicle to stay in place for a long time to effectively reduce the large-scale dust in the area where the dust suppression vehicle is located. Summary of the Invention

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The present application discloses a pure electric dust suppression vehicle. 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.

[0040] Reference Figure 1 and Figure 3 The fog cannon barrel 2 is arranged on the vehicle body 1, and a fan 21 is provided at one end. The fan 21 is used to provide wind force for blowing the dust suppression curing agent.

[0041] Reference Figure 2 and Figure 3 The central liquid pipe 3 is arranged in the mist cannon barrel 2, and 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 mist cannon barrel 2. All the support plates 31 support the central liquid pipe 3 at the center position of the mist cannon barrel 2.

[0042] The fixed liquid pipe 4 is arranged on the bottom edge of the end of the fog cannon barrel 2 away from the fan 21. The fixed liquid pipe 4 is adapted to the edge of the fog cannon barrel 2. The fixed liquid pipe 4 is fixedly connected to a fixed bracket 41, and the fixed bracket 41 is fixedly connected to the fog cannon barrel 2.

[0043] There are two adjustable liquid pipes 5, which are symmetrically arranged on the edge of the fog cannon barrel 2 away from the fan 21. The adjustable liquid pipes 5 are adapted to the edge of the fog cannon barrel 2, and the two adjustable liquid pipes 5 are respectively located at both ends of the fixed liquid pipe 4.

[0044] Reference 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 a 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 commonly connected to an adjusting bracket 53. The adjusting bracket 53 is fixed to the fog cannon barrel 2. The middle part of the first inner ring liquid pipe 51 and the middle part of the first outer ring liquid pipe 52 are both rotatably connected to the adjusting bracket 53, so that the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 can be rotated away from the barrel mouth area of ​​the fog cannon barrel 2.

[0045] Among them, the middle parts of the first inner ring liquid tube 51 and the first outer ring liquid tube 52 are both arranged straight, so that the first inner ring liquid tube 51 and the first outer ring liquid tube 52 can be easily rotated relative to the adjustment bracket 53. At the same time, the middle parts of the first inner ring liquid tube 51 and the first outer ring liquid tube 52 are fixedly connected with two rotating pieces 54, and the two rotating pieces 54 are respectively attached to the two sides of the adjustment bracket 53, so that the rotation of the first inner ring liquid tube 51 and the first outer ring liquid tube 52 relative to the adjustment bracket 53 is more stable.

[0046] The central liquid pipe 3, fixed liquid pipe 4, first inner ring liquid pipe 51, and first outer ring liquid pipe 52 are all connected to a liquid supply pipe 32 for introducing a dust suppression and curing agent. Both the central liquid pipe 3 and fixed liquid pipe 4 are connected to multiple direct spray nozzles 33 for directly spraying the dust suppression and curing agent. Both the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are equipped with multiple switch nozzles 6, each with two spraying modes. The first spraying mode is direct spray, which sprays the dust suppression and curing agent directly for precise dust reduction over long distances. The second spraying mode is diffuse spray, which disperses the dust suppression and curing agent for efficient dust reduction over a large area.

[0047] Reference Figure 3 and Figure 4 Each adjustable liquid pipe 5 is connected to a liquid pipe adjustment assembly 7. The liquid pipe adjustment assembly 7 includes a driving member 71, a first push rod 72, a second push rod 73, a first rocker arm 74 and a second rocker arm 75. The driving member 71 is fixed to the inner wall of the fog cannon barrel 2 and is connected to 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 axial direction of the fog cannon barrel 2 under the drive of the driving member 71.

[0048] Among them, reference 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.

[0049] Reference Figure 3 and Figure 4 The end of the first push rod 72 away from the driving member 71 is slidably connected to one end of the first rocker arm 74, and the other end of the first rocker arm 74 is fixedly connected to the middle part of the first inner ring liquid tube 51. The end of the second push rod 73 away from the driving member 71 is slidably connected to one end of the second rocker arm 75, and the other end of the second rocker arm 75 is fixedly connected to the middle part of the first outer ring liquid tube 52. The angle at which the second push rod 73 drives the second rocker arm 75 to swing is twice the angle at which the first push rod 72 drives the first rocker arm 74 to swing, so that the rotation angle of the first outer ring liquid tube 52 is twice the rotation angle of the first inner ring liquid tube 51, thereby not only expanding the spraying area, but also reducing the overlapping area of ​​the spray.

[0050] Reference Figure 3 and Figure 5 A nozzle switching assembly 8 is provided on each first inner ring liquid pipe 51 and each first outer ring liquid pipe 52. The nozzle switching assembly 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 toward the outside of the fog cannon barrel 2, the spraying state of the switching nozzle 6 is switched from direct spraying to scattered spraying.

[0051] During use, when long-distance and precise dust reduction is required, the positions of the first inner circle liquid pipe 51 and the second outer circle liquid pipe 43 are maintained at the mouth of the fog cannon barrel 2. At this time, the switching nozzle 6 is in a 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 circle liquid pipe 51 and the first outer circle liquid pipe 52 can jointly directly spray the dust suppression curing agent. The fan 21 provides wind force to the sprayed dust suppression curing agent, so that the directly sprayed dust suppression curing agent can be sprayed to a distance under the push of wind force, so as to achieve long-distance and precise dust reduction.

[0052] When large-scale and efficient dust reduction is required, the driving member 71 drives the first push rod 72 and the second push rod 73 to move, and the first push rod 72 drives the first rocker arm 74 to swing, so that the first rocker arm 74 drives the first inner ring liquid pipe 51 to rotate toward the outside of the fog cannon barrel 2, and the second push rod 73 drives the second rocker arm 75 to swing, so that the second rocker arm 75 drives the first outer ring liquid pipe 52 to rotate toward the outside of the fog cannon barrel 2. Since, under the same moving stroke, the swing angle of the second rocker arm 75 driven by the second push rod 73 is twice the swing angle of the first rocker arm 74 driven by the first push rod 72, the rotation angle of the first outer ring liquid pipe 52 is twice the rotation angle of the first inner ring liquid pipe 51 Twice, since the rotation angle of the first outer ring liquid tube 52 is inconsistent with the rotation angle of the first inner ring liquid tube 51, the spraying direction of the switching nozzle 6 on the first outer ring liquid tube 52 is inconsistent with the spraying direction of the switching nozzle 6 on the first inner ring liquid tube 51, and since the rotation angle of the first outer ring liquid tube 52 is twice the rotation angle of the first inner ring liquid tube 51, the spraying area of ​​the switching nozzle 6 on the first inner ring liquid tube 51 can be just between the spraying area of ​​the switching nozzle 6 on the first outer ring liquid tube 52 and the spraying area of ​​the direct nozzle 33 on the central liquid tube 3, thereby expanding the spraying area of ​​the dust suppression curing agent and reducing the overlapping area of ​​spraying.

[0053] When the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 are turned to the outside of the fog cannon barrel 2, the spraying state of the switching nozzle 6 can be switched from direct spraying to scattered spraying under the action of the nozzle switching assembly 8, so that the spraying area of ​​the single switching nozzle 6 is increased, thereby expanding the spraying area and the spraying area, and expanding the spraying range of the dust suppression vehicle, so that the spraying range of the dust suppression vehicle is not easily limited to the barrel mouth range 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 ring liquid pipe 51 and the first outer ring liquid pipe 52, the dust suppression vehicle can achieve large-area and efficient dust reduction, and thus the dust suppression vehicle can simultaneously have the effects of long-distance precise dust reduction and large-area and efficient dust reduction.

[0054] Among them, reference Figure 2 The fixed 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. The second inner ring liquid pipe 42 and the second outer ring liquid pipe 43 are both fixedly connected to the fixed bracket 41. When performing long-distance precise dust reduction, the two first inner ring liquid pipes 51 and the second inner ring liquid pipes 42 can be combined into a spraying ring, and the two first outer ring liquid pipes 52 and the second outer ring liquid pipes 43 can also be combined into a spraying ring, so that the two nested spraying rings increase the spraying amount of the dust suppression curing agent and improve the dust reduction effect.

[0055] In particular, refer to Figure 4The sliding connection structure between the first push rod 72 and the first rocker arm 74 is consistent with the sliding connection structure between the second push rod 73 and the second rocker arm 75. The first push rod 72 is connected to an adjusting slide rod 722, and the adjusting slide rod 722 is slidably set in a waist-shaped hole 741 opened on the first rocker arm 74. When the first push rod 72 moves, the adjusting slide rod 722 can slide in the waist-shaped hole 741, and the adjusting slide rod 722 can drive the first rocker arm 74 to swing during the sliding process.

[0056] Specifically, refer to Figure 6 The switching nozzle 6 includes a nozzle 61 , a switching shell 62 , a spraying shell 63 and a switching portion 64 .

[0057] Reference Figure 5 and Figure 6 One end of the nozzle 61 is connected to the first inner ring liquid pipe 51 or the first outer ring liquid pipe 52. A switching housing 62 is integrally connected to the other end of the nozzle 61 and is provided with a plurality of switching holes 621. A spray housing 63 is slidably mounted on the other end of the nozzle 61. The spray housing 63 is provided with a plurality of diffuse spray holes 631 and is fixedly provided with a straight spray pipe 632. The straight spray pipe 632 is slidably mounted on the switching housing 62. When the dust suppression and curing agent is sprayed from the straight spray pipe 632, it is sprayed in a straight direction. When the dust suppression and curing agent is sprayed from the diffuse spray holes 631, it is sprayed in a diffuse direction.

[0058] Reference Figure 6 When the direct injection pipe 632 slides out of the nozzle 61, the switching part 64 is used to close the switching hole 621 and conduct the direct injection pipe 632 so that the nozzle 61 is connected to the direct injection pipe 632. When the direct injection pipe 632 slides into the nozzle 61, the switching part 64 is used to close the direct injection pipe 632 and conduct the switching hole 621 so that the nozzle 61 is connected to the injection shell 63 through the switching hole 621.

[0059] When direct spraying is required, the injection shell 63 is slid so that the direct injection pipe 632 slides out of the nozzle 61. At this time, the switching part 64 can close the switching hole 621 to prevent the dust suppression curing agent in the nozzle 61 from flowing into the space between the injection shell 63 and the direct injection pipe 632, and the switching part 64 can conduct the direct injection pipe 632 so that the dust suppression curing agent can be sprayed out from the direct injection pipe 632; when scattered spraying is required, the injection shell 63 is slid in the opposite direction so that the direct injection pipe 632 slides into the nozzle 61. At this time, the switching part 64 closes the direct injection pipe 632 to prevent the dust suppression curing agent in the nozzle 61 from flowing into the direct injection pipe 632, and the switching part 64 can conduct the switching hole 621 so that the dust suppression curing agent can flow into the space between the injection shell 63 and the direct injection pipe 632 and be sprayed out from the scattered injection hole 631, so that the spraying state of the switching nozzle 6 can be switched by sliding the injection shell 63.

[0060] Further, refer to Figure 6 The switching portion 64 includes a switching tube 641 , a direct spray sealing piece 642 and a diffuse spray sealing piece 643 .

[0061] The switching tube 641 is located within the nozzle 61 and is sleeved over the direct injection tube 632. The switching tube 641 is integrally connected to the switching housing 62, and the end of the switching tube 641 away from the switching housing 62 is tapered. Multiple direct injection sealing pieces 642 are provided and elastically connected around the axis of the direct injection tube 632 to the end of the direct injection tube 632 near the tapered end of the switching tube 641. The direct injection sealing pieces 642 are elastically attached to the inner wall of the switching tube 641, and the tapered end of the switching tube 641 gathers all the direct injection sealing pieces 642 to seal the direct injection tube 632. One end of the diffuser sealing piece 643 is fixedly connected to the outer wall of the direct injection tube 632, and is slidably arranged in the switching slide hole 6411 opened on the switching tube 641. When the direct injection sealing piece 642 is attached to the switching tube 641, the diffuser sealing piece 643 closes the switching hole 621. When the direct injection sealing piece 642 is gathered, the diffuser sealing piece 643 opens the switching hole 621.

[0062] The direct injection sealing piece 642 is integrally formed and connected to the direct injection pipe 632 , and the connection between the direct injection sealing piece 642 and the direct injection pipe 632 is elastic.

[0063] 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 in a constricted shape, when the direct injection pipe 632 drives the direct injection sealing piece 642 to slide into the nozzle 61, all the direct injection sealing pieces 642 will be gathered together under the guidance of the constricted end of the switching pipe 641. The gathered direct injection sealing pieces 642 can close the direct injection pipe 632. Since the scattered spray sealing piece 643 is fixed to the direct injection pipe 632, the scattered spray sealing 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 conductive.

[0064] When the direct injection pipe 632 slides out of the nozzle 61, the direct injection pipe 632 can drive the direct injection closing piece 642 away from the contracted end of the switching pipe 641. Under the elastic force of 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 dispersed injection 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.

[0065] Specifically, refer to Figure 6The 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 .

[0066] There are multiple groups of switching springs 81, and they are arranged one-to-one between the injection shell 63 and the nozzle 61. Each group of switching springs 81 is provided with multiple switching springs, and multiple switching springs 81 are arranged around the axial direction of the nozzle 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 nozzle 61. The switching spring 81 is used to drive the straight injection pipe 632 to slide out of the nozzle 61.

[0067] Reference Figure 5 and Figure 6 There are multiple switching ropes 82, one end of the switching ropes 82 is fixedly connected to the injection shell 63 one by one, and there are multiple first guide rings 83, which are fixedly connected to the nozzle 61 one by one. The end of the switching rope 82 away from the injection shell 63 slides through the first guide ring 83. Under the guidance of the first guide ring 83, no matter from which direction the switching rope 82 is pulled, the straight injection pipe 632 can be driven to slide into the nozzle 61. The transmission rope 84 is fixedly connected to the end of all the switching ropes 82 away from the injection shell 63. Pulling the transmission rope 84 can simultaneously drive all the switching ropes 82 to move.

[0068] Under the elastic force of the switching spring 81, the injection shell 63 can put the direct injection pipe 632 into a conducting state and the switching hole 621 into a closed state, so that the switching nozzle 6 can be in a direct spraying state; when the transmission rope 84 is pulled, the transmission rope 84 can pull all the switching ropes 82 connected to it to move, and the switching rope 82 can pull the injection shell 63 to slide under the guidance of the first guide ring 83, so that the direct injection pipe 632 slides into the nozzle 61, which can put the direct injection pipe 632 into a closed state and put the switching hole 621 into a conducting state, so that the switching nozzle 6 can be in a scattered spraying state, so that the spraying states of all the switching nozzles 6 on the first inner circle liquid pipe 51 or the first outer circle liquid pipe 52 are easy to switch synchronously.

[0069] Further, refer to Figure 4 and Figure 5 In order to ensure that the switching timing of the switching nozzle 6 can 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 also includes a second guide ring 85. There are four second guide rings 85. The four second guide rings 85 are arranged in a matrix on the adjustment bracket 53. The second guide rings 85 are fixedly connected to the adjustment bracket 53, and the middle part of the transmission rope 84 passes through the four second guide rings 85 one by one.

[0070] Reference Figure 4The first push rod 72 and the second push rod 73 are both provided with a slot 721 at the end away from the driving member 71. The middle position of the transmission rope 84 corresponding to the first inner ring liquid tube 51 is located on the moving path of the slot 721 on the first push rod 72. The slot 721 of the first push rod 72 is used to clamp the transmission rope 84 corresponding to the first inner ring liquid tube 51 when the first push rod 72 moves, so as to push the transmission rope 84 to move. The middle position of the transmission rope 84 corresponding to the first outer ring liquid tube 52 is located on the moving path of the slot 721 on the second push rod 73. The slot 721 of the second push rod 73 is used to clamp the transmission rope 84 corresponding to the first outer ring liquid tube 52 when the second push rod 73 moves, so as to push the transmission rope 84 to move.

[0071] When the first push rod 72 and the second push rod 73 move, the first push rod 72 can clamp the transmission rope 84 corresponding to the first inner circle liquid tube 51 into the slot 721 on itself. The first push rod 72 can stably push the transmission rope 84 corresponding to the first inner circle liquid tube 51 to move through the slot 721, so that the transmission rope 84 can drive all the switching ropes 82 corresponding to the first inner circle liquid tube 51 to move, so that all the switching nozzles 6 corresponding to the first inner circle liquid tube 51 can switch states synchronously.

[0072] The second push rod 73 can clamp the transmission rope 84 corresponding to the first outer ring liquid tube 52 into the card slot 721 on itself. The second push rod 73 can stably push the transmission rope 84 corresponding to the first outer ring liquid tube 52 to move through the card slot 721, so that the transmission rope 84 can drive all the switching ropes 82 corresponding to the first outer ring liquid tube 52 to move, so that all the switching nozzles 6 corresponding to the first outer ring liquid tube 52 can switch states synchronously, so that the switching timing of the switching nozzle 6 can be stably synchronized with the rotation timing of the first inner ring liquid tube 51 and the first outer ring liquid tube 52.

[0073] Reference 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 to the transmission rod 711, and the ends of the first push rod 72 and the second push rod 73 are fixedly connected to the side wall of the transmission rod 711. The driving member 71 can simultaneously provide driving force to the first push rod 72 and the second push rod 73 through the transmission rod 711.

[0074] Reference Figure 3 and Figure 5 In order to ensure that the dust suppression curing agent sprayed by the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 after rotation can also be blown by the wind force of the fan 21, a guide component 9 is provided on the support plate 31, and the guide component 9 includes a diverter plate 91, a guide plate 92 and a guide part 93.

[0075] There are multiple diverter plates 91, and they are fixedly connected between two adjacent support plates 31 in a one-to-one correspondence. There are multiple guide plates 92 and guide parts 93, and they are in a one-to-one correspondence. The multiple guide plates 92 correspond one-to-one to the multiple diverter plates 91 corresponding to the adjustable liquid pipes 5. The guide part 93 is connected to the end of the diverter plate 91 away from the fan 21 and is connected to the guide plate 92.

[0076] The end of the transmission rod 711 away from the driving member 71 is fixedly connected to a connecting frame 712, and the connecting frame 712 is hinged to the end of multiple guide plates 92 corresponding to the adjustable liquid pipe 5 close to the fan 21. When the driving member 71 drives the first inner ring liquid pipe 51 and the first outer ring liquid pipe 52 to rotate toward the outside of the fog cannon barrel 2, the guide part 93 is used to tilt the guide plate 92 driven by the transmission rod 711 in a direction away from the diverter plate 91.

[0077] All the diverter plates 91 divide the wind force of the fan 21 into two parts. The first part of the wind force flows in the area surrounded by all the diverter plates 91, and the second part of the wind force flows in the area between all the diverter plates 91 and the fog cannon barrel 2. When performing long-distance precise dust reduction, 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 curing agent can be sprayed to a distance. When performing large-scale and efficient dust reduction, the transmission rod 711 not only drives the first push rod 72 and the second push rod 73 to move, but also drives the guide plate 92 through the connecting frame 712. Movement, under the guiding action of the guide portion 93, the guide plate 92 can tilt in the direction away from the diverter plate 91 to form a guiding slope. At this time, the blowing direction of the first part of the wind force remains unchanged to blow the dust suppression curing agent sprayed by the central liquid pipe 3, and the blowing direction of the second part of the wind force will blow the dust suppression curing agent scattered by the first inner circle liquid pipe 51 and the first outer circle liquid pipe 52 under the guiding action of the guiding slope formed by the guide plate 92, so that the dust suppression curing agent sprayed by the first inner circle liquid pipe 51 and the first outer circle liquid pipe 52 can also be blown by the wind.

[0078] Further, refer to Figure 5 The guide portion 93 includes a guide plate 931 and a sliding seat 932 .

[0079] The guide plate 931 is fixedly connected to the end of the diverter plate 91 and is located on the side of the diverter plate 91 close to the adjustable liquid tube 5. The guide plate 931 is set at an angle to the diverter plate 91. The sliding seat 932 is hinged on the side of the guide plate 931 away from the diverter plate 91. The sliding seat 932 is slidably set in the guide groove 921 opened on the guide plate 92.

[0080] When the hinged end of the guide plate 92 and the connecting frame 712 gradually approaches the guide plate 931, the guide plate 92 will be tilted by the driving force transmitted by the guide plate 931 through the sliding seat 932. Since the sliding seat 932 slides on the guide plate 92 and rotates relative to the guide plate 931, the guide plate 92 can always maintain a connection with the guide plate 931 during the deflection process, and the guide plate 931 is not likely to hinder the tilting of the guide plate 92.

[0081] Reference Figure 3 and Figure 5 After the guide plate 92 is tilted, the dust suppression curing agent on the leeward side of the guide plate 92 is difficult to be blown by the wind. In order to enable the dust suppression curing agent on the leeward side of the guide plate 92 to be blown by the wind, a plurality of ventilation holes 922 are opened on the guide plate 92. The ventilation holes 922 pass through the guide plate 92. The opening direction of the ventilation holes 922 is set at an angle to the plate surface of the guide plate 92. When the guide plate 92 is tilted to the maximum angle, the opening direction of the ventilation holes 922 is parallel to the axial direction of the fog cannon barrel 2.

[0082] Because when the guide plate 92 is tilted to the maximum angle, the opening direction of the ventilation hole 922 can be parallel to the axial direction of the fog cannon barrel 2, so that a small part of the second part of the wind force will directly pass through the ventilation hole 922. The wind force passing through the ventilation hole 922 can blow on the dust suppression curing agent on the leeward side of the guide plate 92, so that the dust suppression curing agent on the leeward side of the guide plate 92 can also be blown by the wind.

[0083] The implementation principle of a pure electric dust suppression vehicle in the embodiment of the present application is as follows: when in use, when the position of the adjustable liquid pipe 5 is maintained at the mouth of the fog cannon barrel 2, the switching nozzle 6 is in a direct spraying state, and the direct 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, the dust suppression vehicle can perform long-distance and precise dust reduction. When the adjustable liquid pipe 5 is turned to the outside of the fog cannon barrel 2 under the drive of the liquid pipe adjustment component 7, the spraying direction of the switching nozzle 6 can deviate from the mouth area of ​​the fog cannon barrel 2, and under the joint drive of the nozzle switching component 8 and the liquid pipe adjustment component 7, the spraying state of the switching nozzle 6 is switched from direct spraying to scattered spraying, which not only expands the spraying area but also expands 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 reduction, and thus enabling the dust suppression vehicle to simultaneously have the effects of long-distance and precise dust reduction and large-area and efficient dust reduction.

[0084] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
