[0036] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.
[0037] As shown in Figures 1-5 A swinging water curtain, comprising a plurality of swing parts 2 arranged along a linear array and pivoted to the mounting part 1, and a plurality of nozzle connecting pipes 3 fixedly installed on the swing parts 2 and vertically upwardly distributed from the water outlets;
[0038] A third connecting rod 4 is rotationally arranged between the plurality of swing parts 2;
[0039] Further comprising a transmission assembly driven by a stepping motor 61 to keep a circumferential motion of an eccentric transmission shaft sleeve 7, and one swing part 2 adjacent to the eccentric transmission shaft sleeve 7 is pivoted to the eccentric transmission shaft sleeve 7 through the third connecting rod 4.
[0040] Specifically, in combination with Figure 1 and Figure 2 As shown in the drawings, the swing part 2 in the embodiment comprises a first connecting rod 22 symmetrically welded to one side of the cross beam 21. The two first connecting rods 22 on the same cross beam 21 are installed on the symmetrically welded second connecting rod 11 of the mounting part 1 through a rotating shaft.
[0041] Further, the water supply pipeline 5 in the embodiment is laid on the mounting part 1, and a plurality of equidistantly arranged water pipes 51 are fixedly communicated on the water supply pipeline 5. The soft pipe 52 is fixedly communicated between the water pipes 51 and the nozzle connecting pipes 3, and the soft pipe 52 in the present application replaces the existing technology elbow pipe, reducing the pressure loss of water supply.
[0042] Secondly, the swing direction of the swing part 2 in the embodiment is the axial direction of the water supply pipeline 5.
[0043] More further, the port of the nozzle connecting pipe 3 in the above embodiment is threadedly installed with the nozzle 31.
[0044] Furthermore, the eccentric transmission shaft sleeve 7 in the embodiment can be a bolt and a nut, or a shaft sleeve, and other axial rotation combination structures known to those skilled in the art.
[0045] In the above technology, the stepping motor 61 is installed on one side of the plurality of swing parts 2 and drives the plurality of swing parts 2 to swing by a predetermined amplitude in the form of pulling through the third connecting rod 4. The advantage of installing the stepping motor 61 on one side is that all the swing parts 2 can be synchronously controlled. The original motor is installed in the middle, which causes a synchronization deviation when the swing parts on both sides move, affecting the water curtain effect of the spray.
[0046] As a further provided embodiment of the utility model, in combination withFigure 2 As shown, the end of the third connecting rod 4 rotatably mounted between two adjacent swing parts 2 is welded with a connecting hinge 41, and the two third connecting rods 4 are fixed to form an integral through the bolted connecting hinge 41.
[0047] Specifically, the third connecting rod 4 is mounted on both sides of the beam 21 through the rotating shaft, and the end of each connecting rod 4 is welded with a connecting hinge 41, and the two third connecting rods 4 between the two adjacent beams 21 are connected by the end of the connecting hinge 41, and then fixed by the bolt through the nut and bolt assembly.
[0048] It should be noted that the end of the third connecting rod 4 connected with the eccentric transmission shaft set 7 in the embodiment is a mounting cylinder.
[0049] As further provided in another embodiment of the utility model, in combination with Figure 3 As shown, the transmission assembly includes a mounting frame 53, which is inserted with the output shaft of the stepping motor 61, and is fixed by the bolt through the end face of the mounting frame 53 and the threaded connection with the output shaft;
[0050] The eccentric transmission shaft set 7 includes a mounting seat 71 and a screw rod 72, which are symmetrically provided with a through mounting hole, and the screw rod 72 is threaded through the mounting hole and fixed by the nut and screw rod 72 threaded connection distributed on the opposite sides of the mounting seat 71;
[0051] The mounting seat 71 includes a symmetrical horizontal part, which is symmetrically provided with a through hole for the end of the screw rod 72 to pass through, and is fixed by the nut and screw rod 72 threaded connection distributed on the opposite sides of the horizontal part;
[0052] The mounting seat 71 is not coaxial with the output shaft of the stepping motor 61.
[0053] Specifically, the stepping motor 61 in the embodiment is mounted on the motor mounting seat on the mounting part 1. Then the mounting frame 53 is fixed by the bolt through the end face and the threaded connection with the output shaft.
[0054] Further, the mounting seat 71 in the embodiment is installed by the screw rod 72, so that the nut on the mounting seat 71 is rotated and then the mounting seat 71 is located on the screw rod 72 to slide, so as to change the distance between the mounting seat 71 and the output shaft of the stepping motor 61, and then the nut on the screw rod 72 is rotated and contacted on the side wall of the mounting seat 71, so as to realize the fixation.
[0055] In the subsequent construction process, the nut is loosened, and then the distance between the mounting seat 71 and one of the horizontal parts is adjusted, so that the eccentric distance of the mounting seat 71 relative to the output shaft of the stepping motor 61 is changed, thereby changing the swing amplitude of the swing part 2.
[0056] In detail, with Figure 3 the position shown, when the mounting seat 71 is close to the upper horizontal part, the swing amplitude of the swing part 2 is increased when the equipment is started again. Conversely, if the mounting seat 71 is close to the output shaft of the stepper motor 61, the swing amplitude of the swing part 2 is reduced when the equipment is started again.
[0057] And when the above adjustment is completed, the screw rod 72 is locked again by using the nut.
[0058] As further provided by the utility model, in combination with Figure 4 As shown, the eccentric transmission shaft sleeve 7 includes an adjusting shaft 73, a first ring 731 is fixedly arranged on the adjusting shaft 73, and a circular groove is formed in the first ring 731;
[0059] Further comprising a plurality of steel balls 74 distributed in the circular groove, a buckling plate 75 is pressed and fixed on the end face of the first ring 731, a plurality of limiting holes are formed in the buckling plate 75, which are circumferentially and equidistantly distributed and used for exposing the outer side of the steel ball 74;
[0060] The adjusting shaft 73 passes through the center hole formed in the center of the mounting seat 71, and one end of the center hole is provided with a first embedding groove for embedding the first ring 731;
[0061] The track seat 76 is threadedly installed in the first embedding groove, and the exposed outer side of the steel ball 74 is in rolling connection with the track groove on the track seat 76.
[0062] Specifically, with Figure 4 The adjusting shaft 73 is inserted from left to right through the center hole on the mounting seat 71, and the first ring 731 is embedded in the first embedding groove on the mounting seat 71 after being inserted. The first embedding groove here is coaxial with the center hole.
[0063] Further, the plurality of steel balls 74 in the circular groove of the first ring 731 in the above embodiment are arranged equidistantly and circumferentially through the limiting holes on the buckling plate 75, and are in rolling connection with the track groove on the track seat 76 in the first embedding groove.
[0064] Further, in combination with Figure 5 It can be seen that the other end of the center hole in the embodiment is also provided with a second embedding groove consistent with the specification of the first embedding groove, and the track seat 76 is threadedly installed in the second embedding groove;
[0065] The second ring 732 is threadedly connected to the adjusting shaft 73, the steel ball 74 is located in the circular groove formed in the second ring 732 and is fixed by the buckling plate 75 pressed and fixed on the end face of the second ring 732, and the outer side of the steel ball 74 is exposed by the limiting hole;
[0066] The exposed outer side of the steel ball 74 is in rolling connection with the track groove on the track seat 76.
[0067] Specifically, the second ring 732 is screwed on the adjusting shaft 73, and as the screw is advanced, the second ring 732 is embedded in the second embedding groove. Since the second ring 732 and the first ring 731 are both used to install the steel ball 74, as the second ring 732 is embedded in the second embedding groove, the steel ball 74 on the second ring 732 is in rolling connection with the track groove on the track seat 76. Then the rubber pad is inserted on the adjusting shaft 73, and then the mounting cylinder is inserted on the adjusting shaft 73, and finally the rubber pad is inserted on the adjusting shaft 73 and two nuts are screwed on the adjusting shaft 73, so that the mounting cylinder is firmly fixed on the adjusting shaft 73.
[0068] It should be noted that the axial length of the second ring 732 is greater than the axial length of the second embedding groove, and is in abutting connection with the third connecting rod 4 passing through the adjusting shaft 73.
[0069] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
