During use, it includes a pump truck support frame, a power box fixedly mounted on the support frame, four movable wheels movably mounted on the bottom side of the support frame, a pump truck frame itself, and a silent water pump fixedly mounted on a buffer base. The silent water pump is compatible with the power box. A fixed rod is fixedly mounted on the support frame, and a telescopic rod is slidably mounted on the fixed rod. The movable wheels allow the silent water pump to be quickly moved to any location, reaching places inaccessible by trailers, and enabling easy relocation by personnel. This facilitates emergency deployment. Simultaneously, the buffer base on the bottom of the silent water pump utilizes internal buffer springs to absorb some of the impact, thereby reducing vibration and noise.

[0004] Although existing technologies can improve the reduction of noise during the operation of drainage pump trucks, there are still some shortcomings in the process. The noise reduction efficiency is low, and the noise can harm the hearing health of operators. Utility Model Content

[0005] The purpose of this utility model is to provide a large-flow mobile drainage pump truck for flood emergency response, in order to solve the problems mentioned in the background art, such as the low noise reduction efficiency of drainage pump trucks during operation and the harm of noise to the hearing health of operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flood emergency high-flow mobile drainage pump vehicle, including a vehicle body, a power unit and a drainage pump body fixedly connected to the top surface of the vehicle body, a modular sound insulation component provided on the outside of the power unit and the drainage pump body, the modular sound insulation component acting on the power unit and the drainage pump body to achieve sound absorption and noise reduction of the power unit and the drainage pump body, and a towing frame provided on one side of the vehicle body.

[0007] As a preferred technical solution of this application, the modular sound insulation component includes a first mounting post and a second mounting post fixedly connected to the top surface of the vehicle body. There are four first mounting posts and two second mounting posts. Sound insulation panels are inserted and installed between the first mounting posts and between the first and second mounting posts. The top of the first mounting posts, the second mounting posts and the sound insulation panels are provided with sound insulation covers. The sound insulation panels and the sound insulation covers are made of aluminum alloy. Sound-absorbing cotton is adhered to the inner wall of the sound insulation panels and the sound insulation covers. Heat dissipation holes are opened on the surface of the sound insulation panels and the sound insulation covers.

[0008] As a preferred technical solution of this application, a first connecting block is provided on the outer side of both the first mounting post and the second mounting post. The first connecting block is located on both sides of the first mounting post and on three sides of the second mounting post. A toothed slot is provided on the inner wall of the first connecting block.

[0009] As a preferred technical solution of this application, the sound insulation board is provided with a second connecting block on both sides, the two sides of the second connecting block are L-shaped, and the interior of the second connecting block is provided with toothed inserts.

[0010] As a preferred technical solution of this application, the top surfaces of the first mounting post and the second mounting post are both provided with threaded grooves, and the top of the soundproof cover is provided with a fixing screw.

[0011] As a preferred technical solution of this application, a first connecting pipe is provided on one side of the drainage pump body, and a second connecting pipe is provided on the other side of the drainage pump body.

[0012] As a preferred technical solution of this application, the bottom of the power unit and the drain pump body is provided with a buffer pad, which is made of rubber.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This flood emergency high-flow mobile drainage pump truck adopts a composite structure of aluminum alloy sound insulation board and sound-absorbing cotton. High-density materials block mid-to-high frequency noise, and combined with the sound energy conversion mechanism of porous materials, it significantly reduces the reflected noise of diesel engine combustion and impeller rotation. Rubber buffer pads are installed at the bottom of the power unit and the drainage pump body to absorb mechanical vibrations during equipment operation. Annular buffer sleeves are installed on the outer walls of the first and second connecting pipes to block the transmission of water flow impact vibrations to the sound insulation board, effectively reducing noise. Furthermore, the modular sound insulation components utilize a dual fixing mechanism of toothed insertion and mechanical compression, with the L-shaped second connecting block wrapping around the first connecting block to construct a three-dimensional fastening system, solving the problem of easy loosening in traditional splicing structures. Specific details are as follows:

[0014] 1. When the diesel generator and drainage pump are working, noise will be generated. The sound insulation board and sound insulation cover are made of aluminum alloy, and the sound-absorbing cotton is made of porous material, which can effectively reduce reflected sound and reverberation. In addition, rubber buffer pads are set at the bottom of the power unit and drainage pump body to effectively absorb the mechanical vibration of the equipment during operation. At the same time, the annular buffer sleeves on the outer walls of the first and second connecting pipes are made of elastic rubber material. The vibration generated by the water flow impact is absorbed by the buffer pads, preventing the vibration from being transmitted to the sound insulation board and avoiding noise from harming the hearing health of the operators.

[0015] 2. Insert the sound insulation panels sequentially between the first mounting posts and between the first and second mounting posts. The toothed inserts engage with the toothed slots, and the second connecting block has L-shaped sides. The second connecting block wraps around the first connecting block, effectively improving the tightness of the installation. The sound insulation cover is aligned with the threaded grooves on the top of the first and second mounting posts by fixing screws and tightened, further pressing the sound insulation panels to ensure seamless joints. This guarantees the stability and sealing of the overall structure, thereby improving sound insulation performance. Furthermore, the modular sound insulation components can be quickly assembled and disassembled, effectively improving work efficiency. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a high-flow mobile drainage pump truck for flood emergency response.

[0025] Example 1: To address the issue of low noise reduction efficiency and the harm to operators' hearing caused by noise during the operation of drainage pump trucks, please refer to... Figures 1-3 and Figure 5 The vehicle includes a body 1, with a power unit 2 and a drainage pump body 3 fixedly connected to the top surface of the body 1. Modular sound insulation components 4 are provided on the exterior of the power unit 2 and the drainage pump body 3. A tow frame 7 is provided on one side of the body 1. Figure 4 As shown, the modular sound insulation component 4 includes first mounting posts 401 and second mounting posts 402 fixedly connected to the top surface of the vehicle body 1. There are four first mounting posts 401 and two second mounting posts 402. Sound insulation panels 403 are inserted and installed between the first mounting posts 401 and between the first mounting posts 401 and the second mounting posts 402. Sound insulation covers 404 are provided on the top of the first mounting posts 401, second mounting posts 402, and sound insulation panels 403. The sound insulation panels 403 and sound insulation covers 404 are made of aluminum alloy, and sound-absorbing cotton 411 is adhered to the inner walls of the sound insulation panels 403 and sound insulation covers 404. Heat dissipation holes are provided on the surfaces of the sound insulation panels 403 and sound insulation covers 404. Figure 4 As shown, a first connecting pipe 5 is provided on one side of the drainage pump body 3, and a second connecting pipe 6 is provided on the other side of the drainage pump body 3. A buffer sleeve 412 is attached to the outer wall of both the first connecting pipe 5 and the second connecting pipe 6. The buffer sleeve 412 is annular in shape and is adhered to one side of the inner wall of the sound insulation panel 403. Figure 3 As shown, the bottom of the power unit 2 and the drain pump body 3 is equipped with a buffer pad, which is made of rubber.

[0026] In use, the vehicle body 1 can be towed by the towing frame 7. The power unit 2 is usually a diesel generator set, which provides power to the motor of the drainage pump body 3. When the diesel generator is working, it will generate noise, and the drainage pump body 3 will also generate noise when it is working. The sound insulation panel 403 and the sound insulation cover 404 are made of aluminum alloy, whose high density can effectively block the transmission of mid-to-high frequency noise. The sound-absorbing cotton 411 bonded to the inner wall of the sound insulation panel 403 and the sound insulation cover 404 is a porous material. When noise propagates in the sound insulation cavity, the sound waves will enter the pores of the sound-absorbing cotton 411 and convert the sound energy into heat energy through friction and adhesion, thereby significantly reducing reflected sound and reverberation sound, especially the diesel engine combustion noise and the drainage pump impeller rotation. The noise absorption effect is good, and the rubber buffer pads at the bottom of the power unit 2 and the drainage pump body 3 can effectively absorb the mechanical vibration during equipment operation, preventing the vibration from being transmitted to the ground or surrounding structures through the vehicle body 1, reducing noise caused by vibration. In addition, the annular buffer sleeve 412 on the outer wall of the first connecting pipe 5 and the second connecting pipe 6 is made of elastic rubber material. The vibration generated by the water flow impact is absorbed by the buffer sleeve 412, preventing the vibration from being transmitted to the sound insulation plate 403. At the same time, the heat dissipation holes opened on the surface of the sound insulation plate 403 and the sound insulation cover 404 allow air circulation, preventing the temperature inside the sound insulation cavity from becoming too high due to the heat generated by the equipment. While ensuring heat dissipation efficiency, noise is minimized, avoiding noise from harming the hearing health of the operators.

[0027] Example 2: Figures 4-6 The technical solution shown includes a first connecting block 405 on the outer side of both the first mounting post 401 and the second mounting post 402. The first connecting block 405 is located on both sides of the first mounting post 401 and on three sides of the second mounting post 402. The inner wall of the first connecting block 405 is provided with a toothed slot 406. Figure 6 As shown, the sound insulation panel 403 has second connecting blocks 407 on both sides. The two sides of the second connecting blocks 407 are L-shaped, and the interior of the second connecting blocks 407 has toothed inserts 408, such as... Figure 4 As shown, the top surfaces of the first mounting post 401 and the second mounting post 402 are both provided with threaded grooves 409, and the top of the soundproof cover 404 is provided with a fixing screw 410.

[0028] In use, the sound insulation plate 403 is inserted sequentially between the first mounting posts 401 and between the first mounting posts 401 and the second mounting posts 402. The toothed insert 408 on the inner wall of the second connecting block 407 engages with the toothed slot 406 on the inner wall of the first connecting block 405. The toothed structure increases the tightness of the contact surface. At the same time, the two sides of the second connecting block 407 are L-shaped, and the second connecting block 407 wraps around the first connecting block 405, effectively improving the tightness of the installation. After the sound insulation plate 403 is installed with the first mounting posts 401 and the second mounting posts 402, the sound insulation cover 404 is aligned with the threaded groove 409 on the top of the first mounting posts 401 and the second mounting posts 402 by fixing screws 410 and tightened, further pressing the sound insulation plate 403 to ensure that there are no gaps at the splice, ensuring the stability and sealing of the overall structure, thereby improving the sound insulation performance. In addition, the modular sound insulation component 4 can be quickly disassembled and assembled, effectively improving work efficiency.

[0029] The above is the entire working process of the device, and the contents not described in detail in this specification are existing technologies known to those skilled in the art.
