[0001] This application relates to the field of road cleaning, and in particular to a water spraying device and a road cleaning vehicle. Background Technology

[0002] A road cleaning vehicle is a specialized vehicle used for cleaning urban roads. It is typically equipped with a large vacuum cleaner, sweeping equipment, and a water spraying system, enabling it to effectively remove garbage, dust, and other debris from roads. Among these, the water spraying system is a particularly important component of a road cleaning vehicle.

[0003] In related technologies, a water spraying device includes a mounting base, a water inlet pipe, and a spray head. The mounting base is fixedly connected to the frame of a road cleaning vehicle, the water inlet pipe is fixedly connected to the mounting base and the water inlet end is connected to a water tank, and the spray head is fixedly connected to the water outlet end of the water inlet pipe to achieve water spraying, thereby spraying and washing dirt on the road surface, curbs, etc.

[0004] In practical applications, the height of the spray nozzles sometimes needs to be adjusted for different road surfaces to ensure the washing effect. However, the above-mentioned spray device is difficult to adjust the height of the spray nozzles, so it needs to be improved. Utility Model Content

[0005] To facilitate adjustment of the height of the spray head, this application provides a water spraying device.

[0006] The water spraying device provided in this application adopts the following technical solution:

[0007] A water spraying device includes a mounting post, a connecting seat, a limiting component, a water inlet pipe, and a spray head, all mounted on a road cleaning vehicle. The connecting seat is slidably connected to the mounting post along its length. The limiting component includes an abutment bolt, an abutment plate, and a spring. The abutment bolt is threaded to the mounting post and abuts against the lower side of the connecting seat. The abutment plate is slidably connected to the mounting post, and the spring is located between the mounting post and the abutment plate to drive the abutment plate to abut against the upper side of the connecting seat. The water inlet pipe is located on the connecting seat, with one end connected to a water tank, and the spray head is connected to the other end of the water inlet pipe.

[0008] By adopting the above technical solution, in practical applications, the abutting bolt abuts against the lower side of the connecting seat, and the abutting plate abuts against the upper side of the connecting seat under the drive of the spring, so as to limit the connecting seat and thus realize the limited installation of the water inlet pipe and the spray head; when it is necessary to adjust the height of the spray head, by rotating the abutting bolt, the connecting seat and the abutting plate move upward and compress the spring, or the connecting seat and the abutting plate move downward under the drive of the spring, so as to complete the adjustment of the height of the connecting seat, thereby realizing the adjustment of the height of the spray head. The operation is simple and convenient, thus facilitating the adjustment of the height of the spray head.

[0009] Preferably, the upper end of the mounting post is threaded to the road cleaning vehicle.

[0010] By adopting the above technical solution, the upper end of the mounting post is threadedly connected to the road cleaning vehicle to facilitate the installation of the mounting post, thereby making it easier to install the water spraying device on the road cleaning vehicle.

[0011] Preferably, the lower end of the mounting column is provided with a rotating groove.

[0012] By adopting the above technical solution and setting a rotating groove, the mounting column can be rotated, thereby facilitating the installation of the mounting column.

[0013] Preferably, the upper end of the mounting post is slidably connected to a limiting block along its own length direction, and the upper end of the spring elastically abuts against the limiting block to drive the limiting block to be embedded in the road cleaning vehicle, thereby restricting the rotation of the mounting post.

[0014] By adopting the above technical solution, after the mounting column is threadedly connected to the road cleaning vehicle by setting a limit block, the limit block abuts against the road cleaning vehicle under the drive of the spring, so as to restrict the rotation of the mounting column and ensure that the mounting column does not rotate during the rotation of the abutting bolt, thereby improving the stability of adjusting the height of the water spray head.

[0015] Preferably, the connecting seat has a connecting groove and a deformation groove along its own length direction, the water inlet pipe is movably inserted through the connecting groove, one side of the deformation groove is connected to the connecting groove and the other side is inserted through it, and the width of the deformation groove is reduced by the abutting bolt and the abutting plate abutting the connecting seat.

[0016] By adopting the above technical solution and setting the connecting groove and deformation groove, it is convenient to adjust the position and angle of the water inlet pipe, and also to facilitate the installation and disassembly of the water inlet pipe.

[0017] Preferably, a force-applying plate is provided on the lower side of the connecting seat.

[0018] By adopting the above technical solution and setting a force-applying plate, force can be applied to the connecting seat facing upwards, thereby facilitating stable adjustment of the spray head height.

[0019] Preferably, a force-applying rod is provided on the upper side of the connecting seat.

[0020] By adopting the above technical solution and setting a force-applying rod, it is easy to apply force to the connecting seat upwards, thereby facilitating the adjustment of the position between the water inlet pipe and the connecting seat.

[0023] A road cleaning vehicle includes the water spraying device described above.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When it is necessary to adjust the height of the spray head, the connecting seat and the abutment plate are moved upward by rotating the abutment bolt, which compresses the spring, or the connecting seat and the abutment plate are moved downward by the spring to adjust the height of the connecting seat, thereby adjusting the height of the spray head. The operation is simple and convenient, which makes it easy to adjust the height of the spray head.

[0026] 2. By setting a limit block, after the mounting column is threadedly connected to the road cleaning vehicle, the limit block abuts against the road cleaning vehicle under the drive of the spring, so as to restrict the rotation of the mounting column and ensure that the mounting column does not rotate during the rotation of the abutting bolt, thereby improving the stability of adjusting the height of the water spray head;

[0027] 3. By setting connecting grooves and deformation grooves, the position and angle of the water inlet pipe can be adjusted, and the installation and disassembly of the water inlet pipe can also be facilitated. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a water spraying device.

[0036] Reference Figure 1 The water spraying device includes a mounting column 1, a connecting seat 2, a limiting component 3, a water inlet pipe 4, and a spray head 5. The mounting column 1 is vertically set and installed on the road cleaning vehicle. The connecting seat 2 is slidably connected to the mounting column 1, and the sliding direction is the length direction of the mounting column 1.

[0037] Reference Figure 1 and Figure 2 The limiting component 3 includes an abutment bolt 31, an abutment plate 32, and a spring 33. The abutment bolt 31 is threadedly connected to the mounting post 1 and abuts against the lower side of the connecting seat 2. The abutment plate 32 is slidably connected to the mounting post 1 along its length and is located above the connecting seat 2. The spring 33 is sleeved on the mounting post 1, with one end elastically abutting against the mounting post 1 and the other end elastically abutting against the upper side of the abutment plate 32, thereby driving the abutment plate 32 to abut against the upper side of the connecting seat 2, so that the connecting seat 2 is clamped between the abutment bolt 31 and the abutment plate 32.

[0038] The water inlet pipe 4 is installed on the connector 2, and one end of the water inlet pipe 4 is connected to the water tank. The spray head 5 is fixedly connected to the other end of the water inlet pipe 4 so that the spray head 5 is connected to the water inlet pipe 4.

[0039] In practical applications, the abutting bolt 31 abuts against the lower side of the connecting seat 2, and the abutting plate 32 abuts against the upper side of the connecting seat 2 under the drive of the spring 33, so as to limit the connecting seat 2, thereby realizing the limited installation of the water inlet pipe 4 and the spray head 5.

[0040] When the height of the spray head 5 needs to be adjusted, the connecting seat 2 and the abutment plate 32 are moved upward by rotating the abutment bolt 31, compressing the spring 33, or the connecting seat 2 and the abutment plate 32 are moved downward under the drive of the spring 33. This adjusts the height of the connecting seat 2, thereby adjusting the height of the spray head 5. The operation is simple and convenient, facilitating the adjustment of the spray head 5's height. It should be noted that applying force upward to the connecting seat 2 compresses the spring 33 on the abutment plate 32, making it easier to rotate the abutment bolt 31 to adjust the spray head 5's height. Simultaneously, the spring 33 reduces the movement of the connecting seat 2 during the vibration of the road cleaning vehicle, decreasing wear on the connecting seat 2 and improving the stability of the spray device.

[0041] In some embodiments, the upper end of the mounting post 1 is threaded to the road cleaning vehicle. The mounting post 1 can be installed by rotating it, so as to facilitate the installation between the mounting post 1 and the road cleaning vehicle, thereby facilitating the installation of the water spraying device on the road cleaning vehicle.

[0042] In some embodiments, a rotating groove 11 is provided at the lower end of the mounting post 1. The rotating groove 11 is hexagonal in shape so that a hexagonal wrench or an electric wrench can be inserted to facilitate the rotation of the mounting post 1, thereby facilitating the installation of the mounting post 1.

[0043] In some embodiments, the upper end of the mounting post 1 is slidably connected to the limiting block 12, and the sliding direction is the length direction of the mounting post 1. The limiting block 12 is arranged in a rectangular block shape, and the upper end of the spring 33 elastically abuts against the limiting block 12. When the mounting post 1 is threadedly connected to the road cleaning vehicle, the limiting block 12 moves upward under the drive of the spring 33 and is embedded in the bottom of the road cleaning vehicle to restrict the mounting post 1 from rotating, so as to ensure that the mounting post 1 does not rotate during the rotation abutting bolt 31, thereby improving the stability of adjusting the height of the spray head 5.

[0044] In some embodiments, the connecting seat 2 has a connecting groove 21 and a deformation groove 22 along its length. The water inlet pipe 4 is movably inserted through the connecting groove 21. One side of the deformation groove 22 is connected to the connecting groove 21, and the other side is through the groove. The width of the deformation groove 22 can be reduced by the abutting bolt 31 and the abutting plate 32 abutting against the connecting seat 2, so as to achieve the fastening of the connecting seat 2 to the water inlet pipe 4. By releasing the abutting bolt 31 or the abutting plate 32 from the connecting seat 2, the deformation groove 22 can be enlarged. At this time, the water inlet pipe 4 can be moved or rotated, thereby facilitating the adjustment of the position and angle of the water inlet pipe 4, and also facilitating the installation and disassembly of the water inlet pipe 4.

[0045] In some embodiments, the lower side of the connecting seat 2 is bent downward to form a force-applying plate 23, so as to apply force upward to the connecting seat 2, thereby facilitating stable adjustment of the height of the spray head 5. When force is applied upward to the force-applying plate 23, the width of the deformation groove 22 is kept small, thereby ensuring the fixation of the water outlet pipe.

[0046] In some embodiments, a force-applying rod 24 protrudes from the upper side of the connecting seat 2 to apply force upwards to the connecting seat 2, thereby facilitating the adjustment of the position between the water inlet pipe 4 and the connecting seat 2. When force is applied upwards to the force-applying rod 24, the width of the deformation groove 22 can be increased, thereby facilitating the adjustment of the position and angle of the water inlet pipe 4.

[0047] The implementation principle of this embodiment is as follows: In actual application, the abutting bolt 31 abuts against the lower side of the connecting seat 2, and the abutting plate 32 abuts against the upper side of the connecting seat 2 under the drive of the spring 33, so as to limit the connecting seat 2, thereby realizing the limited installation of the water inlet pipe 4 and the spray head 5.

[0048] When the height of the spray head 5 needs to be adjusted, the connecting seat 2 and the abutment plate 32 are moved upward by rotating the abutment bolt 31, compressing the spring 33, or the connecting seat 2 and the abutment plate 32 are moved downward under the drive of the spring 33. This adjusts the height of the connecting seat 2, thereby adjusting the height of the spray head 5. The operation is simple and convenient, facilitating the adjustment of the spray head 5's height. It should be noted that applying force upward to the connecting seat 2 compresses the spring 33 on the abutment plate 32, making it easier to rotate the abutment bolt 31 to adjust the spray head 5's height. Simultaneously, the spring 33 reduces the movement of the connecting seat 2 during the vibration of the road cleaning vehicle, decreasing wear on the connecting seat 2 and improving the stability of the spray device.

[0049] This application also discloses a road cleaning vehicle.

[0050] Reference Figure 3 The road cleaning vehicle includes a frame 6 and a water spraying device as described in the above embodiments, with the mounting post 1 threadedly connected to the bottom of the frame 6.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
