[0024] 2. The design of the driving mechanism can use the flow of water as a driving force to realize the circumferential rotation of the spray box, thereby increasing the spraying and dust reduction range. Furthermore, the slidable design of the cross tube can use the centrifugal force generated during the rotation of the spray box to drive the cross tube to move, thereby achieving the purpose of adjusting the spraying range by rotating speed and automatically preventing the cross tube from being blocked.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0037] Embodiment 1: In order to solve the problems existing in the prior art, that is, in a limited construction environment, to protect the dust reduction equipment body from possible collisions or scratches, etc., the following is disclosed: Figure 1-Figure 2 The scheme shown includes a spray box 1 for installing a nozzle 6 and a cross pipe 7, a bottom plate 8 for supporting the spray box 1, and a base 3 for connecting the bottom plate 8, and the two are connected by a supporting mechanism, and the supporting mechanism includes at least three support rods 2, and the top of the support rod 2 is inclined toward the base 3 or the central axis of the spray box 1. At the same time, a partial section of the support rod 2 is made of non-rigid material, and a cavity for accommodating a flowing medium is opened in the support rod 2. After the medium flows out of the cavity, the non-rigid section of the support rod 2 flexibly retracts. Since the interior of a part or all of the support rod 2 is made of flexible material, when the hoisting equipment collides with the dust reduction equipment as a whole, the support rod 2 itself can be deformed by elastic means To buffer the impact force, and the internal cavity of the support rod 2 is also used to accommodate a flowing medium such as water or air. When there is water or air inside, on the one hand, it can unload and buffer the impact force, and on the other hand, when the water or air inside is discharged, the support rod 2 will flexibly retract to the base 3, and together with the spray box 1 at its top end, it will be retracted into the base 3. Therefore, compared with the traditional rigid or ordinary disassembly structure, the flexible support rod 2 in this solution can very conveniently complete the rapid storage and disassembly of the dust reduction equipment by directly draining water or exhausting air. When the entire section of the support rod 2 adopts a flexible pipe structure, even if it is damaged by collision, directly replacing the corresponding pipeline structure is lower in cost than the alloy material in traditional means.

[0038] The solution disclosed in this embodiment also includes the following Figure 3-Figure 4As shown in the figure, the control valve 5 can be a valve structure with electric control or manual control or other control. The support rod 2 is distributed at equal angles with respect to the central axis of the base 3 or the spray box 1, wherein the non-rigid material section of the support rod 2 is distributed in its middle section, top section, bottom section or the entire section, and a control valve 5 connected to its internal cavity is installed on the support rod 2, wherein the control valve 5 is located at the top or bottom end of the support rod 2, and the output port of the control valve 5 is distributed toward the outside or the central axis of the dust suppression equipment, and is mainly used to discharge the flowing medium in the support rod 2 when necessary, for example, to discharge part of the medium in one of the support rods 2, and when the internal pressure becomes low, its top The spray box 1 at the bottom will tilt toward that side, thereby cooperating with the multi-angle spraying of the spray box 1 itself to achieve a more comprehensive dust reduction operation. At the same time, when the control valves 5 on multiple support rods 2 are opened at the same time, if the control valve 5 is set at the upper half of the support rod 2, then the section of the support rod 2 where the control valve 5 is set will collapse and soften first, so that the output port of the control valve 5 can move toward the spray box 1 when the spray box 1 moves downward as a whole, which can instead play the effect of using the medium sprayed therein to clean the spray box 1 itself, and the control valve 5 can be used to control the rate of medium leakage, thereby controlling the movement speed of the spray box 1.

[0039] Embodiment 2: According to Figure 5-Figure 6 The contents shown in the figure are further expanded on the basis of the above scheme in this embodiment. A counterweight ball 9 is further provided under the bottom plate 8. The counterweight ball 9 is installed on the lower end surface of the bottom plate 8 through a plurality of obliquely distributed connecting cables 10. By using the counterweight ball 9, the spray box 1 can maintain stable movement on the central axis of the base 3 when moving downward. On the other hand, when a collision occurs, the shaking of the counterweight ball 9 can produce a damper effect to further weaken the shaking force caused by the collision.

[0040] In this embodiment, the problem to be solved is that in the prior art, if the global adjustment of the dust suppression equipment is to be achieved, too many electric control devices are often required, which leads to high overall cost and complex construction environment, and the damage rate is also higher. Therefore, the following is disclosed: Figure 7-Figure 8In the scheme shown in the figure, the spray box 1 is rotatably mounted on the bottom plate 8 through the vertical shaft 11, wherein a driving mechanism is installed at the bottom end of the vertical shaft 11 and driven by the water flow entering the spray box 1, the driving mechanism comprises an impeller 12 installed at the bottom end of the vertical shaft 11 and a receiving space wrapped around the impeller 12, the bottom end of the water pipe 4 is connected to the water supply equipment, and the top end is connected to the receiving space, the top and bottom ends of the vertical shaft 11 are respectively provided with openings 13, and the upper and lower groups of openings 13 are both connected to the internal hollow of the vertical shaft 11, and the water flow sprayed from the water pipe 4 drives the impeller 12 and enters the spray box through the opening 13 In the spray box 1, when the water flows into the water pipe 4, its impact force will directly act on the impeller 12. Since the impeller 12 is fixedly installed at the bottom end of the vertical shaft 11, the vertical shaft 11 will synchronously drive the spray box 1 fixed at its top to rotate synchronously. At the same time, after impacting the impeller 12, the water will enter the interior of the vertical shaft 11 through the opening 13 in the lower half of the vertical shaft 11, and enter the spray box 1 through the opening 13 in the upper half of the vertical shaft 11, and then will be finally sprayed out from the nozzle 6 through the horizontal pipe 7 connected to the interior of the spray box 1. Therefore, the spray box 1 can achieve dust reduction in a wider range during the process of water flow driven rotation.

[0041] like Fig. 9 As shown, this embodiment can further expand the content about the specific functions of the cross pipe 7 on the basis of the above embodiments. The cross pipe 7 is horizontally slidably installed on the side wall of the spray box 1, and a horizontally distributed cross bar 14 is fixed inside the spray box 1. The cross pipe 7 is horizontally elastically slidably installed on the cross bar 14 through a spring. The inner end of the cross pipe 7 is a water inlet knot with a filter, and the cross bar 14 slides through the center of the inner end of the cross pipe 7. At the same time, an impact plate 15 is installed at the end of the cross bar 14, and an annular thin plate 17 with an inner diameter consistent with the outer diameter of the impact plate 15 is also provided inside the cross pipe 7. At the same time, the thin plate 17 in the initial state is located on the right side of the impact plate 15, and the left space of the impact plate 15 is provided with a one-way water return hole 16 installed on the cross pipe 7.

[0042] First, when the spray box 1 itself is in a state of high-speed rotation, the centrifugal force will swing the horizontal tube 7 outward for a certain distance. That is to say, in the process of spraying and dust reduction, the lateral movement distance of the horizontal tube 7 can be controlled by controlling the rotation speed of the spray box 1, thereby achieving the effect of adjusting the spraying range. At the same time, in the initial stage of water supply, when the horizontal tube 7 moves toward the outside, the impact plate 15 will pass through the inner hole of the thin plate 17 in a certain period of time. In this process, since the impact plate 15 is close to the direction of the input port of the horizontal tube 7 at this time, the impact plate 15 will play a role of recoil the input port of the horizontal tube 7 during the process of passing through the inner hole, thereby preventing impurities in the water from clogging the filter for a long time.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
