Description

Technical Field

[0001] This utility model relates to the field of sprinkler trucks, and in particular to a low-noise water pump structure for sprinkler trucks. Background Technology

[0002] Water sprinkler trucks, also known as spray trucks, multi-functional water sprinkler trucks, landscaping water sprinkler trucks, water tankers, and water transport trucks, are suitable for washing various road surfaces, watering trees, green belts, and lawns, road and factory construction, and high-rise building washing. They have functions such as watering, dust suppression, high and low-level spraying, pesticide spraying, and guardrail washing. They also have functions such as water transport, drainage, and emergency fire fighting.

[0003] The water spraying function of a sprinkler truck relies on an internally installed water pump to provide water pressure. The water pump, installed at the bottom of the vehicle, generates considerable noise when the sprinkler truck is in operation, which negatively impacts pedestrians and nearby residents. Furthermore, since the water pump is only connected to the sprinkler truck via an L-shaped support plate, disassembly and installation are cumbersome during maintenance. Therefore, a low-noise water pump structure for sprinkler trucks is proposed to solve the above problems. Utility Model Content

[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] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a low-noise water pump structure for a sprinkler truck, including a mounting plate 1 and a pump body 7. The mounting plate 1 is used to mount other components and is fixedly connected to the sprinkler truck body. The pump body 7 is a sprinkler truck water pump, which is an existing structure and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The rear surface of the mounting plate 1 has a sliding groove 6 for adjusting the vertical sliding of the adjustment component 3. The bottom of the mounting plate 1 is provided with a noise reduction mounting mechanism, which includes components for reducing the noise of the sprinkler truck water pump. The noise reduction component 2 includes a mounting rod 24 for mounting a soundproof cover 21. The mounting rod 24 is fixedly connected to the bottom of the mounting plate 1 and is fixed by the mounting plate 1. The inner wall of the mounting rod 24 is rotatably connected to a soundproof cover 21 for soundproof protection of the pump body 7. The inner wall of the soundproof cover 21 is fixedly connected to a sound-absorbing pad 22 for absorbing the noise generated by the operation of the pump body 7. The inner wall of the sound-absorbing pad 22 is provided with a sound-absorbing groove 23 for increasing the sound absorption effect of the sound-absorbing pad 22. The outer wall of the soundproof cover 21 is provided with a mounting groove 25 for providing space for the installation of the pump body 7.

[0031] Reference Figure 2 , Figure 3 The noise reduction installation mechanism also includes an adjustment component 3 for convenient disassembly and maintenance of the pump body 7. The adjustment component 3 includes a connecting plate 31 for mounting the pump body 7. The connecting plate 31 is installed at the bottom of the pump body 7 for fixing the pump body 7. A moving plate 35 for moving the connecting plate 31 is fixedly connected to the rear surface of the connecting plate 31. A connecting block 33 for adjusting the moving plate 35 is fixedly connected to the rear surface of the moving plate 35. A lead screw 34 for moving the connecting block 33 is provided on the inner wall of the connecting block 33. A rotating wheel 32 for controlling the rotation of the lead screw 34 is fixedly connected to the outer wall of the lead screw 34. The connecting block 33 is slidably connected to the inner wall of the sliding groove 6 to limit the movement range of the connecting block 33. The lead screw 34 is rotatably connected to the inner wall of the mounting plate 1 and driven by the rotating wheel 32. The moving plate 35 is slidably connected to the front surface of the mounting plate 1 and connected by the mounting plate 1.

[0032] Reference Figure 2 , Figure 3 , Figure 4 The pump body 7 has a water outlet connector 8 on its top, which connects to the water outlet pipe of the sprinkler truck. A connecting shaft 5 is located on the left side of the pump body 7, used to connect to a motor to drive the pump body 7. A water inlet connector 9 is located on the right side of the pump body 7, connecting to the water inlet pipe of the sprinkler truck. Since the pump body 7 needs to be connected to other components inside the sprinkler truck during installation, the soundproof cover 21 must be installed in a way that avoids interfering with these connections. Three sets of mounting slots 25 are provided, each corresponding to a different water outlet connector 8, water inlet connector 9, and water outlet pipe. The edge of the mounting groove 25 and the connecting shaft 5 do not contact the pump body 7 when the soundproof cover 21 rotates. The soundproof cover 21 and the mounting plate 1 are detachably connected by the buckle 4. When installing the pump body 7, the soundproof cover 21 can be rotated open first to expose the pump body 7 before disassembly. The sound absorption groove 23 is set in the shape of a hexagonal frustum. Multiple sets of sound absorption grooves 23 are arranged in a honeycomb array on the inner wall of the sound absorption pad 22, so that the sound inside the sound absorption pad 22 is reflected inside, which can reduce the sound transmission effect to the outside, thereby completing the noise reduction effect of the pump body 7.

[0033] Working principle: When the pump body 7 is running, the soundproof cover 21 forms an openable and closable space through the rotational support of the mounting rod 24. In the closed state, it covers the pump body 7 with the mounting plate 1 through the buckle 4, so that the entire pump body 7 is wrapped in the isolation cavity formed by the soundproof cover 21 and the sound-absorbing pad 22. The hexagonal frustum-shaped sound-absorbing grooves 23 set in the inner wall of the sound-absorbing pad 22 form a honeycomb sound wave labyrinth structure. After the sound waves enter the sound-absorbing grooves 23, they undergo multiple reflections and interferences between multiple inclined walls. Through the principle of sound energy conversion, the sound wave energy is gradually converted. Furthermore, the hexagonal frustum-shaped structure of the sound-absorbing grooves 23 allows the sound waves to be reflected multiple times, effectively extending the sound wave attenuation path length. During maintenance, the operator first releases the locking of the buckle 4, rotates the soundproof cover 21 outward around the mounting rod 24 to open it, so that the three sets of mounting slots 25 are disengaged from the connection areas of the water outlet connection seat 8, water inlet connection seat 9 and connecting shaft 5 of the pump body 7. At this time, the screw 34 can be driven to rotate by rotating the wheel 32, which drives the connecting block 33 to move vertically along the sliding groove 6, so that the moving plate 35 drives the connecting plate 31 and the pump body 7 to descend as a whole, realizing the non-destructive separation from the vehicle body connecting pipeline. This adjustment process ensures that the pump body 7 moves smoothly along the predetermined trajectory through the guiding cooperation of the sliding groove 6 and the connecting block 33, avoiding the collision of parts caused by traditional disassembly methods.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
