Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a dust suppression device for building construction. Background Art

[0002] During construction at existing construction sites, most of them will generate a large amount of dust, which leads to a high content of dust and other impurity particles in the air near the construction site, greatly reducing the environmental quality around the construction site. Therefore, according to environmental protection requirements, it is necessary to fence off and carry out dust reduction treatment around the construction site.

[0003] Most existing dust reduction methods are spray dust reduction, that is, atomizing nozzles are installed at the enclosure, and water is pressurized and transported to the atomizing nozzles through the water supply pipe, and then sprayed out, continuously performing atomizing dust reduction operations near the enclosure to reduce the impact on the quality of the surrounding environment of the construction site. However, this dust reduction method usually involves tying a water supply pipe equipped with multiple atomizing nozzles to the upper end of the enclosure, and the length of the nozzle is set and extended along the length of the enclosure. Since the length of the water supply pipe is fixed along the distribution direction of the enclosure, the distance at which the atomizing nozzles on the water supply pipe spray water is fixed, and the dust reduction area that can be affected is also fixed and limited. As a result, there are defects such as a small dust reduction area and poor dust reduction effect, and further improvement is needed. Summary of the Invention

[0004] In order to improve the dust reduction effect, the present application provides a construction dust reduction device.

[0005] This application provides a construction dust suppression device that adopts the following technical solutions:

[0006] A dust reduction device for construction includes an enclosure, a first water spray pipe arranged on the top of the enclosure, a first nozzle arranged on the first water spray pipe, a rotating frame rotatably connected to the enclosure for installation of the first water spray pipe, a water supply mechanism for supplying water to the first water spray pipe, and a driving mechanism for driving the rotating frame to rotate; the rotating frames are arranged in a plurality of intervals along the length direction of the enclosure, the number of the first water spray pipes corresponds to the number of the rotating frames, the first nozzles are arranged in a plurality of intervals along the length direction of the first water spray pipe, and the plane formed by the first water spray pipe as the rotating frame rotates is parallel to the plate surface of the enclosure.

[0007] By adopting the above technical solution, the driving mechanism is used to drive the rotating frame to rotate forward or reverse, thereby realizing the adjustment of the spraying position of the first nozzle at different height positions and horizontal positions. Compared with the fixed position spraying of the first nozzle in the prior art, the dust reduction range is effectively expanded, the dust reduction effect is improved, and the flexibility and coverage of the spraying area are further ensured, solving the problem of small dust reduction area caused by traditional fixed water pipes.

[0008] Preferably, the driving mechanism includes a traction rope, a ring provided on the first water spray pipe for the traction rope to pass through, a driving component connected to one end of the traction rope for winding or unwinding, and a reset component for driving the rotating frame to reset. A first water hose is connected between adjacent first water spray pipes, one traction rope corresponds to one enclosure or multiple enclosures, one first water spray pipe is provided with at least two rings, one traction rope is passed through the rings on several first water spray pipes, and the end of the traction rope away from the driving component is fixedly connected to the enclosure.

[0009] By adopting the above technical solution, the traction rope passes through the ring provided on the first water spray pipe, and one end of the traction rope is reeled or unreeled by the driving component, thereby driving the first water spray pipe and the first nozzle thereon to move. This design effectively expands the working coverage of the first nozzle, so that the dust reduction area is no longer limited to fixed points, and realizes a wider range of spatial dust reduction treatment, significantly improving the dust reduction efficiency and effect of the entire construction process. At the same time, one traction rope can be used for one or more enclosures, which enhances the applicability and economy of the device. In addition, the design of at least two rings on each first water spray pipe further ensures uniform and stable force during traction, thereby improving the reliability of system operation.

[0010] Preferably, the traction rope includes a threading section arranged parallel to the length direction of the first water spray pipe, a first connecting section connected to two adjacent threading sections, a second connecting section for connecting to the enclosure, and a third connecting section for connecting to the drive assembly, and the two ends of the threading section are respectively threaded through the two threading rings.

[0011] By adopting the above technical solution, the traction rope consists of a threading section, a first connecting section, a second connecting section and a third connecting section, wherein the threading section is arranged parallel to the length direction of the first water spray pipe to ensure the stability of the traction force transmission; the first connecting section connects two adjacent threading sections to form a continuous structure of the traction rope to adapt to the layout requirements of multiple first water spray pipes; the second connecting section is used to connect with the enclosure to ensure the fixity of the traction system; the third connecting section is connected to the drive assembly to realize power input for the entire traction process.

[0012] It should be noted that for the initial position of the first water pipe under the reset assembly, as the traction rope is pulled, the first water pipe can be rotated within an angle range of 0-180 degrees. Since the first nozzle is arranged on the first water pipe, when it is rotated 180 degrees, the coverage area is the widest and the area covered by dust reduction is the largest.

[0013] Preferably, the drive assembly includes an installation box connected to the traction rope, a first gear built into the installation box, two first racks respectively arranged on the top wall and bottom wall of the installation box to engage with the first gear, and a first drive motor that drives the first gear to rotate, and the first gear is an incomplete gear.

[0014] By adopting the above technical solution, utilizing the incomplete first gear and the two first racks, the first drive motor can drive the first gear to rotate in the same direction, thereby achieving intermittent winding and unwinding of the traction rope. This design makes the movement of the traction rope more precise and controllable, effectively adjusting the position of the first water spray pipe, further optimizing the spray range and dust reduction effect of the first nozzle. Furthermore, this design reduces wear on the first drive motor compared to directly rotating the first drive motor forward or reverse.

[0015] Preferably, the first nozzle is a hollow conical nozzle, and the hollow conical nozzle has a built-in second nozzle, the second nozzle is an atomizing nozzle, and several atomizing nozzles are connected to a second water spray pipe, the diameter of the second water spray pipe is smaller than the diameter of the first water spray pipe, the length direction of the second water spray pipe is parallel to the length direction of the first water spray pipe, and two adjacent second water spray pipes are connected to a second water supply hose.

[0016] By adopting the above technical solution, the setting of the hollow cone nozzle can expand the spraying range of a single first nozzle and increase the dust reduction coverage area; the design of the built-in atomizing nozzle helps to improve the atomization effect of water and supplement the range that the hollow cone nozzle cannot cover, thereby enhancing the dust reduction ability; the introduction of the second water pipe realizes the separate water supply to the atomizing nozzle, avoiding the influence of insufficient pressure of the first water pipe on the atomization effect; the smaller diameter design of the second water pipe can reduce water waste while ensuring smooth water flow; the parallel arrangement of the second water pipe and the first water pipe and the connection of the first water supply hose ensure the compactness and flexibility of the overall structure, further improving the working efficiency and applicability of the dust reduction device.

[0017] Preferably, the first water spray pipe includes a first pipe, two second pipes respectively slidably sleeved on the first pipe and a spring arranged between the two second pipes, the two ends of the spring are respectively connected to the second pipes at the two ends, and the spring forces the two second pipes to move away from each other; the first nozzle is arranged on the second pipe, and a first guide plate is provided on the enclosure, and two first guide plates are provided and symmetrically arranged along the axis of the rotating frame, and both of the second pipes are protruding with an abutment rod for abutting against the first guide plate, and an adjustment mechanism is provided on the enclosure for adjusting the distance between the two first guide plates.

[0018] By adopting the above technical solution, the first water spray pipe consists of a first pipe and two second pipes that are slidably sleeved on the first pipe. The second pipes at both ends are connected by a spring, so that the two second pipes are separated from each other in the absence of external force. At the same time, two first guide plates are provided on the enclosure, symmetrically distributed along the axis of the rotating frame. When the driving mechanism drives the water spray pipe to rotate, the abutment between the abutment rods provided on the water spray pipe and the first guide plates changes the length of the water spray pipe during the rotation of the driving mechanism, thereby changing the spray position of the nozzle. In conjunction with the adjustment mechanism, the distance between the two first guide plates can be precisely controlled according to actual needs to further optimize the position of the first water spray pipe, so that the range of the nozzle spray is suitable for a large area with a low dust height, or a small area with a high dust height. Therefore, the spray range of the corresponding first nozzle can be adjusted according to actual conditions to ensure that the first nozzle covers the optimal dust reduction area, ultimately achieving the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

[0019] Preferably, the first guide plate is an arc-shaped plate, and the axis of the arc-shaped plate is located between the two arc-shaped plates.

[0020] By adopting the above technical solution, the first guide plate is set as an arc-shaped plate, which can guide the abutment rod on the first pipe to move along the arc path of the arc-shaped plate, so that the first water spray pipe can achieve a smoother expansion or contraction action during the rotation process.

[0021] Preferably, the adjustment mechanism includes a connecting rod connecting the two first guide plates, a mounting bracket provided on the enclosure for rotational connection of the connecting rod, and a control component for controlling the rotation angle of the connecting rod.

[0022] By adopting the above technical solution, the connecting rod connects the two first guide plates, the mounting frame provides a rotation support point for the connecting rod, and the control component accurately adjusts the rotation angle of the connecting rod to different angles to achieve flexible adjustment of the vertical distance between the two first guide plates relative to the rotation point of the first water pipe, thereby better adapting to different dust reduction scenarios.

[0023] At the same time, by adjusting the spacing between the first guide plates, the telescopic state of the first water spray pipe can be further optimized, ensuring that the coverage range of the first nozzle is wider and more uniform, and effectively improving the dust reduction effect.

[0024] Preferably, the control assembly includes a control plate arranged on the mounting frame and bolts passing through the control plate, the mounting frame includes a second fixed plate connected to the enclosure and a second rotating shaft rotatably passing through the second fixed plate, the second rotating shaft is connected to the connecting rod, the second rotating shaft is fixedly connected to the control plate, the control plate is penetrated by a through hole for the bolt to pass through, and a number of the through holes are arranged at intervals around the axis of the control plate, and the bolts are threadedly connected to the mounting frame.

[0025] By adopting the above technical solution, the control plate is used to rotate according to the dust conditions on site to change the angle formed between the length direction of the first guide plate and the length direction of the enclosure. When it is rotated to the required position, bolts are inserted through the holes in the control plate and threaded into the mounting bracket to fix the angle of the first guide plate at this time. The spacing between the two first guide plates is adjusted by driving the connecting rod. This design not only improves the operational convenience of the adjustment process, but also ensures that the first water spray pipe can flexibly adapt to different dust reduction requirements during operation, enhancing the dust reduction effect while ensuring the stability of equipment operation.

[0026] Preferably, the control assembly includes a second gear provided on the mounting frame, a second rack engaged with the second gear, and a driving member for driving the second rack to slide along the length direction of the enclosure.

[0027] By adopting the above technical solution, the meshing transmission of the second gear and the second rack enables the connecting rod to rotate when the driving member pushes the second rack to slide, thereby adjusting the position of the first guide plate. This design not only simplifies the operation process, but also improves the adjustment accuracy, further optimizes the telescopic range of the water spray pipe, and indirectly improves the dust reduction coverage area and effect.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. By setting up a rotating frame and a driving mechanism, the first water spray pipe and the first nozzle thereon can be driven to adjust to different heights and horizontal positions, effectively expanding the coverage of the first nozzle, solving the problem of limited area of ​​traditional fixed spray dust reduction, and significantly improving the dust reduction effect;

[0030] 2. By cooperating with the two first racks, the first drive motor can drive the first gear to rotate in the same direction, thereby achieving intermittent winding and unwinding of the traction rope. This design makes the movement of the traction rope more precise and controllable, effectively adjusting the position of the first water spray pipe, and further optimizing the spray range and dust reduction effect of the first nozzle.

[0031] 3. By providing an adjustment mechanism, the distance between the two first guide plates can be precisely controlled according to actual needs to further optimize the position of the first water spray pipe, so that the spray range of the nozzle can be adapted to a large area with a small dust height, or a small area with a high dust height. In this way, the spray range of the corresponding first nozzle can be adjusted according to actual conditions to ensure that the first nozzle covers the best dust reduction area, thereby ultimately achieving the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-10 , further details of this application are given.

[0044] The embodiment of the present application discloses a dust suppression device for construction.

[0045] Example 1:

[0046] A construction dust suppression device, referring to Figure 1 、 Figure 2 , including an enclosure 1, a first water spray pipe 2 arranged on the top of the enclosure 1, a first nozzle 3 arranged on the first water spray pipe 2, a rotating frame 4 rotatably connected to the enclosure 1 for installation of the first water spray pipe 2, a water supply mechanism 5 for supplying water to the first water spray pipe 2, and a driving mechanism 6 for driving the rotating frame 4 to rotate.

[0047] Among them, a number of rotating racks 4 are arranged at intervals along the length direction of the enclosure 1, and the number of the first water spray pipes 2 corresponds to the number of the rotating racks 4.

[0048] Reference Figure 2 、 Figure 3The rotating frame 4 specifically includes a first fixing plate 41 fixedly connected to the upper surface of the enclosure 1, a first rotating shaft 42 rotatably connected to the first fixing plate 41, and a connecting head 43 fixedly connected to the first rotating shaft 42. The length direction of the first fixing plate 41 is parallel to the height direction of the enclosure 1, and the length direction of the first rotating shaft 42 is parallel to the thickness direction of the enclosure 1. The connecting head 43 is fixedly connected to the middle part of the first water spray pipe 2, and the length direction of the first water spray pipe 2 is perpendicular to the length direction of the first rotating shaft 42. Among them, the first nozzle 3 can be a hollow cone nozzle or other nozzle such as an atomizing nozzle, and can be specifically set according to needs. Several first nozzles 3 are arranged at intervals along the length direction of the first water spray pipe 2. In this embodiment, two first nozzles 3 are shown, and the two first nozzles 3 are respectively arranged at both ends of the first water spray pipe 2.

[0049] Among them, a first water supply hose 21 is connected between adjacent first water spray pipes 2 to reduce the number of water supply mechanisms 5. Due to the rotation of the rotating frame 4, the first water spray pipe 2 will also rotate accordingly. The first water supply hose 21 is set so that the first water spray pipe 2 can rotate with the rotating frame 4.

[0050] Back to Figure 1 The water supply mechanism 5 specifically includes a water supply pipe 51 connected to one of the first water spray pipes 2 or the first water supply hose 21, a control water pump 52 arranged on the water supply pipe 51, and a water tank 53 connected to the water inlet end of the control water pump 52.

[0051] Reference Figure 2 、 Figure 4 In this embodiment, the drive mechanism 6 specifically includes a traction rope 61, a ring 62 provided on the first water spray pipe 2 for the traction rope 61 to pass through, a drive assembly 63 connected to one end of the traction rope 61 for winding or unwinding, and a reset assembly 64 for driving the rotating frame 4 to reset. At least two rings 62 are provided on each first water spray pipe 2, and the two rings 62 are provided between the two first nozzles 3. One traction rope 61 passes through several rings 62 on the first water spray pipe 2, so that one traction rope 61 is provided for one enclosure 1 or multiple enclosures 1. The end of the traction rope 61 away from the drive assembly 63 is fixedly connected to the enclosure 1.

[0052] For the traction rope 61, specifically, the traction rope 61 includes a threading section 611 arranged parallel to the length direction of the first water spray pipe 2, a first connecting section 612 connected to two adjacent threading sections 611, a second connecting section 613 for connecting to the enclosure 1, and a third connecting section 614 for connecting to the drive assembly 63, and the threading section 611 is passed through the two through rings 62.

[0053] It should be noted that, with respect to the shape setting of the traction rope 61, specifically, the two ends of the first water spray pipe 2 are respectively the first end and the second end. In this regard, for the connection between the first connecting section 612 and the penetration section 611, the two ends of the first connecting section 612 can extend to the first end (second end) of the two adjacent first water spray pipes 2; or one end of the first connecting section 612 is extended to the first end of one of the first water spray pipes 2, and the other end of the first connecting section 612 is extended to the second end of the other first water spray pipe 2. Under the action of the initial reset component 64, the traction rope 61 is set in a broken line.

[0054] As for the driving component 63, it specifically includes an installation box 631 connected to the traction rope 61, a first gear 632 built into the installation box 631, two first racks 633 respectively arranged on the top wall and bottom wall of the installation box 631 to engage with the first gear 632, and a first driving motor 634 that drives the first gear 632 to rotate. The installation box 631 is slidingly connected to the enclosure 1. In this embodiment, the first gear 632 is an incomplete gear, and the enclosure 1 protrudes with a mounting plate 11 for installing the first driving motor 634. The output shaft of the first driving motor 634 rotates and passes through the mounting plate 11.

[0055] Reference Figure 3 In this embodiment, the reset component 64 is specifically a torsion spring, which is coaxially sleeved on the first rotating shaft 42. A mounting ring 421 is fixedly sleeved on the first rotating shaft 42. The two ends of the torsion spring are respectively fixedly connected to the surfaces of the first fixing plate 41 and the mounting ring 421 that are close to each other.

[0056] It should be noted that the driving mechanism 6 is used to drive the rotating frame 4 to rotate, so that the plane formed by the first water spray pipe 2 as the rotating frame 4 rotates is parallel to the plate surface of the enclosure 1. For the rotation of the rotating frame 4, the driving mechanism 6 can also be a separate driving motor, the driving motor is fixedly connected to the first fixed plate 41, and the output shaft of the driving motor is fixedly connected to the first rotating shaft 42. The driving motor is started to drive the first rotating shaft 42 to rotate, thereby changing the height position and horizontal position of the first nozzle 3 on the first water spray pipe 2, that is, changing the spray range of the first nozzle 3. It should be noted that since the first water supply hose 21 is provided, the selected driving motor needs to be able to realize forward and reverse rotation.

[0057] Since a drive motor is provided to drive the first rotating shaft 42, the number of drive motors provided is relatively large, resulting in a relatively high cost. Therefore, the drive mechanism 6 may further include a rack provided along the length of the enclosure 1, a driving gear and a driven gear meshed with the rack, and a drive motor to drive the driving gear to rotate. The first rotating shaft 42 is fixedly provided through the driven gear. As the drive motor rotates forward or reverse, it drives the rack to slide back and forth along the length of the enclosure 1, thereby driving the first water spray pipe 2 to reciprocate. However, the above two drive mechanisms 6 are relatively more expensive than the traction rope 61, and the specific configuration can be based on the environment and needs.

[0058] The implementation principle of a construction dust reduction device according to an embodiment of the present application is as follows: by utilizing the cooperation between the incomplete first gear 632 and the two first racks 633, the first drive motor 634 can drive the first gear 632 to rotate in the same direction, thereby realizing the intermittent winding and unwinding action of the traction rope 61. Since the traction rope 61 passes through the ring 62 provided on the first water spray pipe 2, it drives the first water spray pipe 2 and the first nozzle 3 thereon to be displaced. This enables the adjustment of the spray position of the first nozzle 3 at different height positions and horizontal positions. Compared with the fixed position spraying of the first nozzle 3 in the prior art, it effectively expands the dust reduction range, improves the dust reduction effect, further ensures the flexibility and coverage of the spraying area, and solves the problem of the small dust reduction area caused by the traditional fixed water spray pipe.

[0059] Example 2:

[0060] Reference Figure 5 , the difference from Example 1 is that, in this embodiment, the first nozzle 3 is a hollow conical nozzle, the hollow conical nozzle has a second nozzle 31 built in the hollow conical nozzle, the second nozzle 31 is an atomizing nozzle, and several atomizing nozzles are connected to a second water spray pipe 311, the diameter of the second water spray pipe 311 is smaller than the diameter of the first water spray pipe 2, the length direction of the second water spray pipe 311 is parallel to the length direction of the first water spray pipe 2, the second water spray pipe 311 is connected to the first water spray pipe 2, and two adjacent second water spray pipes 311 are connected to a second water hose 312, the diameter of the second water hose 312 is smaller than the diameter of the first water hose 21, and the second water hose 312 is connected to the water supply pipe 51, or is connected to the water tank 53, and the specific setting is based on demand.

[0061] Among them, the setting of the hollow cone nozzle can expand the spraying range of the single first nozzle 3 and increase the dust reduction coverage area; the design of the built-in atomizing nozzle helps to improve the atomization effect of water and supplement the range that the hollow cone nozzle cannot cover, thereby enhancing the dust reduction ability and further improving the working efficiency and applicability of the dust reduction device.

[0062] Example 3:

[0063] Reference Figure 6 、 Figure 7 The difference from Example 1 is that the first water spray pipe 2 includes a first pipe 22, two second pipes 23 slidably sleeved on the first pipe 22, and a spring 24 disposed between the two second pipes 23. In this case, the first spray head 3 is disposed on the second pipe 23, and the connector 43 is connected to the first pipe 22, or directly connects the first pipe 22 to the first rotating shaft 42. The two ends of the spring 24 are respectively connected to the second pipes 23 at both ends. A plurality of springs 24 are disposed at intervals around the axis of the first pipe 22, and the springs 24 force the two second pipes 23 to move away from each other.

[0064] In this embodiment, a first guide plate 7 is provided on the enclosure 1. Two first guide plates 7 are provided and are symmetrically arranged along the axis of the rotating frame 4. The length of the first guide plate 7 is longer than the distance between the two first guide plates 7. The two second tubes 23 both protrude with abutment rods 25 for abutting against the first guide plates 7. An adjustment mechanism 8 for adjusting the distance between the two first guide plates 7 is provided on the enclosure 1.

[0065] In this embodiment, the adjustment mechanism 8 specifically includes a connecting rod 81 connecting the two first guide plates 7, a mounting bracket 82 provided on the enclosure 1 for rotationally connecting the connecting rod 81, and a control assembly 83 for controlling the rotation angle of the connecting rod 81. The mounting bracket 82 includes a second fixed plate 821 provided on the enclosure 1 and a second rotating shaft 822 rotatably connected to the second fixed plate 821. The second rotating shaft 822 is a sleeve-shaped structure that is coaxially sleeved on the first rotating shaft 42 with a gap between the second rotating shaft 822 and the first rotating shaft 42. To reduce the impact on the rotation of the first rotating shaft 42, the second rotating shaft 822 is fixedly connected to the connecting rod 81.

[0066] Among them, the control component 83 specifically includes a control plate 831 arranged on the mounting frame 82 and a bolt 832 passing through the control plate 831. The second rotating shaft 822 is fixedly connected to the control plate 831. The control plate 831 is penetrated by a through hole 833 for the bolt 832 to pass through. There are several through holes 833 spaced around the axis of the control plate 831. The second fixed plate 821 is provided with a threaded hole for the bolt 832 to be threadedly connected.

[0067] Two first guide plates 7 are symmetrically arranged along the axis of the rotating frame 4 on the enclosure 1. This allows the length of the first water pipe 2 to be varied during the rotation of the drive mechanism 6, thereby changing the spray position of the first nozzle 3. In conjunction with the adjustment mechanism 8, the distance between the two first guide plates 7 can be precisely controlled according to actual needs, further optimizing the position of the first water pipe 2 and ensuring that the first nozzle 3 covers the optimal dust reduction area, ultimately enhancing the equipment's applicability and improving dust reduction efficiency.

[0068] Example 4:

[0069] Reference Figure 8 , which differs from Example 3 in that, in this embodiment, the control assembly 83 includes a second gear 834 coaxially connected to and sleeved on the second rotating shaft 822, a second rack 835 meshing with the second gear 834, and a driving member for driving the second rack 835 to slide along the length of the enclosure 1. The number of second gears 834 corresponds to the number of connecting rods 81, and the second rack 835 is slidably connected to the enclosure 1.

[0070] In this embodiment, the driving member can be an electric push rod fixedly connected to one end of the second rack 835, or the driving member can include a driving gear engaged with the second rack 835 and a second driving motor that drives the driving gear to rotate. The second driving motor is installed on the enclosure 1 and is specifically set according to needs.

[0071] Starting the driving member to change the rotation angle of several first guide plates 7 simplifies the operation process, improves the adjustment accuracy, further optimizes the telescopic range of the first water spray pipe 2, and indirectly improves the dust reduction coverage area and effect.

[0072] Example 5:

[0073] Reference Figure 9 , which is different from Example 3 in that a second guide plate 71 can be fixedly connected between the two first guide plates 7 to form a guide frame, and the length of the second guide plate 71 is shorter than that of the first guide plate 7. The spray range of the nozzle can be adjusted as needed to adapt to a large area with a low dust height, or a small area with a high dust height. Thus, the spray range of the corresponding first nozzle 3 can be adjusted according to actual conditions to ensure that the first nozzle 3 covers the optimal dust reduction area, ultimately achieving the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

[0074] Furthermore, Figure 10 As shown, the first guide plate 7 is configured as an arc-shaped plate, with the axis of the arc-shaped plate located between the two arc-shaped plates, and the second guide plate 71 is also configured as an arc-shaped plate, thereby forming an elliptical guide frame. This can guide the abutment rod 25 on the second pipe 23 to move along an arc-shaped path, thereby achieving a smoother expansion or contraction of the first water spray pipe 2 during rotation.

[0075] 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.
