Description

Technical Field

[0001] This utility model relates to the field of front-mounted water cannon technology, specifically a front-mounted water cannon device for sprinkler trucks. Background Technology

[0002] Water sprinkler trucks are commonly used in urban road cleaning, greening irrigation, and emergency firefighting. Their front-mounted water cannons are the core component for long-distance water spraying and directional rinsing. Currently, the most mature front-mounted water cannons for water sprinkler trucks on the market are mostly stainless steel electric water cannons. These products have been widely adopted in the water sprinkler truck industry due to the corrosion resistance of stainless steel and the convenience of electric drive.

[0003] Existing stainless steel electric sprinkler cannons typically feature rotation and elevation adjustment functions. An electric actuator drives the cannon body to rotate around a vertical axis to change the spray direction, and simultaneously drives it to rotate around a horizontal axis to adjust the spray elevation angle, thus meeting the spray range requirements in different operational scenarios. Regarding installation, to ensure the stability of the water cannon device during the sprinkler truck's movement and operation, most existing products use four bolts to securely connect the water cannon base to the front mounting bracket of the sprinkler truck, achieving a fixed installation of the water cannon device.

[0004] However, in actual operations, when encountering emergencies (such as the need for precise flushing of localized areas or emergency fire suppression for small-scale fires), workers often need to disassemble the front-mounted water cannon for handheld operation to improve operational flexibility and accuracy. However, existing stainless steel electric sprinkler cannons have significant drawbacks in terms of disassembly and handheld use: on the one hand, they are fixed with four bolts, requiring the use of special tools such as wrenches for disassembly, which is cumbersome and time-consuming, making it impossible to achieve rapid disassembly and failing to meet the timeliness requirements in emergency operation scenarios; on the other hand, the disassembled water cannon device has a cylindrical structure and lacks a dedicated handheld structure. When workers hold it, it is not only difficult to hold it stably, but the weight of the water cannon itself and the recoil force during operation can easily cause instability, affecting the operation effect. It may also slip due to the small contact area between the hand and the smooth stainless steel surface, posing a safety hazard. Therefore, we propose a front-mounted water cannon device for sprinkler trucks. Utility Model Content

[0005] The purpose of this utility model is to provide a front-mounted water cannon device for sprinkler trucks, which has the advantages of quick disassembly and convenient hand-held use, and solves the problem that existing front-mounted water cannon devices have obvious defects in disassembly and hand-held use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front-mounted water cannon device for a sprinkler truck, comprising:

[0007] Mounting frame, bearing plate, U-shaped limit plate, stainless steel electric sprinkler cannon body and sprinkler truck body;

[0008] The mounting frame is bolted to the front chassis of the sprinkler truck, and adjustment connection holes are provided at both ends of the mounting frame.

T-shaped guide rods are fixed at both ends of one side of the U-shaped limiting plate, and the T-shaped guide rods slide on the inner surfaces of both ends of the fixed plate. A through hole is opened on the inner surface of one end of the U-shaped limiting plate, and a hand-tightening bolt is provided inside the through hole.

[0011] The stainless steel electric sprinkler body is located on the top of the support plate. The lower end of the stainless steel electric sprinkler body is provided with a positioning socket that matches the positioning hole. A grip is fixed inside the positioning socket. Limiting breaks are provided on both sides of the limiting ring at the lower end of the stainless steel electric sprinkler body. A hand handle is fixed on one side of the stainless steel electric sprinkler body.

[0012] Preferably, an electrically controlled telescopic rod is installed on the inner side of one end of the mounting frame, and the bottom of the bearing plate is fixedly installed to the protruding end of the electrically controlled telescopic rod by bolts.

[0013] Preferably, both ends of the bottom of the bearing plate are fixed with limit guide rods, and the limit guide rods slide on the inner surface of one end of the mounting frame.

[0015] Preferably, the threaded connection hole corresponds vertically to the through hole, and the lower end of the hand-operated bolt located inside the through hole is screwed into the threaded connection hole.

[0016] Preferably, the limiting ring with limiting breaks on both sides is adapted to the matching groove of the U-shaped limiting plate.

[0017] Preferably, the outer surface of the handheld handle is provided with anti-slip texture.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The components of this application, including the mounting frame 1, adjusting connection hole 101, electrically controlled telescopic rod 102, bearing plate 2, limiting guide rod 201, positioning hole 202, threaded connection hole 203, fixing plate 204, U-shaped limiting plate 3, through hole 301, hand-tightening bolt 302, T-shaped guide rod 303, rubber gasket 304, stainless steel electric sprinkler cannon body 4, limiting break 401, positioning socket 402, grip rod 403, hand grip rod 404, and sprinkler truck body 5, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0031] Example 1

[0032] Please see Figures 1-6 As shown, this utility model provides a technical solution: a front-mounted water cannon device for a sprinkler truck, comprising:

[0033] Mounting frame 1, bearing plate 2, U-shaped limiting plate 3, stainless steel electric sprinkler cannon body 4, and sprinkler truck body 5;

[0034] The mounting frame 1 is bolted to the front chassis of the sprinkler truck body 5, and both ends of the mounting frame 1 are provided with adjustment connection holes 101.

[0035] The support plate 2 is set in the accommodating space formed by the mounting frame 1. The inner surface of the middle end of the support plate 2 is provided with a positioning hole 202 and a threaded connection hole 203. A fixing plate 204 is installed on the top of the support plate 2.

[0036] Among them, the U-shaped limiting plate 3 is placed above the bearing plate 2. T-shaped guide rods 303 are fixed at both ends of one side of the U-shaped limiting plate 3, and the T-shaped guide rods 303 slide on the inner surfaces of both ends of the fixed plate 204. A through hole 301 is opened on the inner surface of one end of the U-shaped limiting plate 3, and a hand-twisted bolt 302 is provided on the inner side of the through hole 301.

[0037] The stainless steel electric sprinkler cannon body 4 is located on the top of the support plate 2. The lower end of the stainless steel electric sprinkler cannon body 4 is provided with a positioning socket 402 that is compatible with the positioning hole 202. A handle 403 is fixed inside the positioning socket 402. A limiting break 401 is provided on both sides of the limiting ring at the lower end of the stainless steel electric sprinkler cannon body 4. A hand handle 404 is fixed on one side of the stainless steel electric sprinkler cannon body 4.

[0038] The threaded connection hole 203 corresponds vertically to the through hole 301, and the lower end of the hand-tightening bolt 302 located in the through hole 301 is screwed into the threaded connection hole 203. The limiting rings of the limiting break 401 on both sides are adapted to the matching grooves of the U-shaped limiting plate 3. The outer surface of the hand handle 404 is provided with anti-slip texture.

[0039] This technical solution involves fixing the mounting frame 1 to the front chassis of the sprinkler truck body 5 with bolts, adjusting the installation position using the adjusting connection hole 101 to ensure the frame is level and secure, placing the stainless steel electric sprinkler cannon body 4 on top of the support plate 2, inserting the positioning socket 402 into the positioning hole 202 for initial positioning, and then sliding the U-shaped limiting plate 3 so that its adapter groove engages with the limiting ring with limiting breaks 401 on both sides (the limiting ring with limiting breaks 401 on both sides matches the adapter groove of the U-shaped limiting plate 3). After the hand-operated bolt 302 is rotated through the through hole 301 (the hand-operated bolt 302 can be a butterfly bolt), it is threaded into the threaded connection hole 203, thereby achieving rapid fastening of the water cannon. At this time, the rubber gasket 304 contacts the top of the limiting ring with limiting breaks 401 on both sides, providing buffering. Then, the stainless steel electric sprinkler body 4 achieves rotation and elevation angle adjustment through the electric actuator to perform long-distance water spraying or rinsing. The hand handle 404 and grip 403 can be used as auxiliary adjustment handles in the fixed state.

[0040] When handheld operation is required, first rotate the hand-tightening bolt 302 to disengage from the threaded connection hole 203 and through hole 301. The U-shaped limiting plate 3 slides outward under the guidance of the T-shaped guide rod 303, releasing the limiting rings with limiting breaks 401 on both sides. Then, lift the stainless steel electric sprinkler body 4 upward to disengage the positioning socket 402 from the positioning hole 202, and you can hold the water cannon. The operator holds the anti-slip texture of the hand handle 404 with one hand to provide friction, and holds the handle 403 with the other hand to achieve stable operation. The electric functions of the water cannon, such as rotation and elevation angle, can be controlled wirelessly or wiredly to ensure operational flexibility.

[0041] During use, regularly check the wear of the threads on the hand-tightening bolt 302 and the threaded connection hole 203, and replace them in time to ensure the tightening force. Through modular design and user-friendly operation, this device realizes the quick conversion between fixed and hand-held modes of the water cannon, which significantly improves the multifunctionality and efficiency of the water truck in urban cleaning, greening irrigation and emergency fire fighting.

[0042] Example 2

[0043] Based on Embodiment 1, this utility model is as follows: Figures 1-6As shown, an electrically controlled telescopic rod 102 is installed on the inner side of one end of the mounting frame 1, and the bottom of the bearing plate 2 is fixed to the protruding end of the electrically controlled telescopic rod 102 by bolts. Both ends of the bottom of the bearing plate 2 are fixed with limit guide rods 201, and the limit guide rods 201 slide on the inner surface of one end of the mounting frame 1.

[0044] This technical solution: By setting up the electrically controlled telescopic rod 102 and the limiting guide rod 201, the electrically controlled telescopic rod 102 inside the mounting frame 1 can drive the bearing plate 2 to rise and fall. Combined with the guiding effect of the limiting guide rod 201, the height of the stainless steel electric sprinkler body 4 can be adjusted. This allows the water cannon to flexibly adjust the spray angle in different operation scenarios such as greening irrigation or road cleaning, expand the coverage area, and the height adjustment can be used to adapt to different working distances or avoid obstacles.

[0045] Example 3

[0046] Based on Embodiment 1, this utility model is as follows: Figures 1-6 As shown, a rubber gasket 304 is adhered to the adapter groove at the bottom of the U-shaped limiting plate 3.

[0047] This technical solution: By setting the rubber pad 304, the rubber pad 304 at the bottom of the U-shaped limiting plate 3 can play a buffering role when fixing the water cannon, reducing the vibration and impact during vehicle driving or operation, protecting the structural integrity of the stainless steel electric sprinkler body 4, and extending its service life.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
