Description

Technical Field

[0001] This utility model relates to the technical field of drainage and flood control vehicles with pump noise reduction structure, specifically a drainage and flood control vehicle with pump noise reduction structure. Background Technology

[0002] Drainage and flood control vehicles are special vehicles designed to respond to emergencies such as floods. The water pump is the most important component inside the drainage and flood control vehicle, and the water pump will continuously make noise during use.

[0003] Publication No.: CN211083305U, Title: A Noise Reduction Base Frame Device for a Heat Pump, which discloses: including a pump house foundation, a main board, a secondary board, and a horizontal pump; the top surface of the pump house foundation has a threaded fixing hole; the bottom of the main board and the secondary board are provided with bearings; a damping spring vibration isolator is rotatably connected inside the bearing; the bottom end of the damping spring vibration isolator is fixedly connected with a fixing screw that mates with the threaded fixing hole; a mounting groove is opened at the center of one side of the main board and the secondary board; a rubber vibration damping pad is fixed at the top of the main board and the secondary board; a connecting plate is fixed at the top of the rubber vibration damping pad; a connecting hole is opened at the top of the connecting plate; an installation plate is fixed at the bottom of the horizontal pump; the surface of the installation plate is provided with an installation hole that mates with the connecting hole; an insert block is fixed at the center of the side of the secondary board opposite to the side where the installation groove is located; a pipe plate is fixed at the center of one edge of the top of the main board and the secondary board; a pipe groove is opened inside the pipe plate; a bent pipe is fixed inside the pipe groove; one end of the bent pipe is connected to the horizontal pump;

[0004] The aforementioned disclosure describes how damping springs and rubber damping pads are used to reduce vibrations generated during the operation of horizontal pumps, thereby reducing noise. However, during the use of water pumps, the pumps continuously generate heat after starting. Overheating can reduce the pump's lifespan or even cause it to shut down, affecting drainage efficiency. Furthermore, during installation, damping pads are typically placed at the bottom of the pump to reduce noise. Over time, these pads become thinner due to pressure and aging. When disassembled and reinstalled after maintenance, the pump's height may be slightly lower than before, affecting the smoothness of reconnection between the pump and the water pipe. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drainage and flood control vehicle with a pump noise reduction structure. This solves the problem that during the use of water pumps, the pumps continuously emit heat after starting, which can reduce their service life or even cause them to shut down, affecting drainage efficiency. Furthermore, during the installation of water pumps, shock-absorbing pads are usually placed at the bottom to reduce noise. However, these pads become thinner under pressure and aging, resulting in the pump being slightly lower than its original height when disassembled, repaired, or reinstalled. This affects the smoothness of reconnecting the pump to the water pipe.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a drainage and flood control vehicle with a pump noise reduction structure, including a mounting base, a cavity at the center of the mounting base, a plurality of clamping devices that slide close to each other on the upper surface of the mounting base, the clamping device including a moving block, an arc-shaped block at the end of the moving block, a buffer component between the arc-shaped block and the moving block, a wind guide device at the bottom of the inner wall of the cavity, the wind guide device including a wind guide plate with a frustum structure, and a squeezing device at the center of the wind guide plate.

[0007] Preferably, a T-shaped block is fixedly connected to the lower surface of the movable block, a T-shaped groove that mates with the T-shaped block is opened on the surface of the mounting base, and an adjustment knob is threadedly connected to the side of the mounting base. The end of the adjustment knob extends into the T-shaped groove and is rotatably connected to the T-shaped block.

[0008] Preferably, the inner side of the arc-shaped block is a frosted rubber block, and a fixing rod is fixedly connected to the outer side of the arc-shaped block. The end of the fixing rod extends into the movable block and is slidably connected thereto. The buffer assembly includes a first spring disposed in the movable block, and the two ends of the first spring are fixedly connected to the movable block and the fixing rod, respectively.

[0009] Preferably, the lower surfaces of the four corners of the mounting base are fixedly connected to fixed feet, the lower surfaces of the fixed feet are provided with buffer pads, the lower surfaces of the fixed feet are provided with several insertion holes, and the upper surfaces of the buffer pads are fixedly connected to multiple plug rods that are inserted into the insertion holes.

[0010] Preferably, the air guide plate is fixedly connected to the mounting base via a connecting plate, and several baffles are fixedly connected to the periphery of the air guide plate. The extrusion device includes an adjusting bolt threaded onto the lower surface of the air guide plate, and the end of the adjusting bolt penetrates through the air guide plate.

[0011] Preferably, a compression pad is provided above one end of the adjusting bolt through the air guide plate, and a plug rod is fixedly connected to the lower surface of the compression pad. The bottom end of the plug rod is slidably inserted into the adjusting bolt. A second spring is provided inside the adjusting bolt, and the two ends of the second spring are fixedly connected to the adjusting bolt and the plug rod, respectively. Beneficial effects

[0012] This utility model provides a drainage and flood control vehicle with a pump noise reduction structure. Compared with the prior art, it has the following advantages:

[0013] (1) The drainage and flood control vehicle with pump noise reduction structure has a cavity in the center of the mounting base. The water pump is installed in the cavity. During the process of pumping water and draining floods in the outside, the air carried by the airflow will enter through the cavity and come into contact with the surface of the water pump, thereby achieving rapid cooling after the water pump is started. The bottom of the inner wall of the cavity is equipped with a wind guide device, so that when the airflow passes under the mounting base, the amount of air entering the cavity is increased under the guidance of the wind guide device, thereby improving the cooling efficiency.

[0014] (2) The drainage and flood control vehicle with pump noise reduction structure is equipped with a squeezing device and a clamping device. The clamping device clamps the periphery of the water pump, thereby realizing the fixed installation of the water pump. During the installation process, by adjusting the height of the squeezing device, the top of the squeezing device abuts against the bottom of the water pump. The change in the height of the squeezing device can drive the change in the height of the water pump during installation, avoiding the error in the height of the water pump during installation, which would affect the connection efficiency between the water pump and the water pipe.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a drainage and flood control vehicle with a pump noise reduction structure, including a mounting base 1, a cavity 12 is provided at the center of the mounting base 1, and a plurality of clamping devices 3 are slidably connected to the upper surface of the mounting base 1, the clamping device 3 includes a moving block 31, an arc-shaped block 33 is provided at the end of the moving block 31, a buffer component is provided between the arc-shaped block 33 and the moving block 31, and a wind guide device 5 is provided at the bottom of the inner wall of the cavity 12, the wind guide device 5 includes a wind guide plate with a frustum structure, and a squeezing device 4 is provided at the center of the wind guide plate.

[0024] Specifically, a cavity 12 is provided in the center of the mounting base 1. The water pump is installed in the cavity 12. During the process of pumping water and draining floodwaters, the air carried by the airflow will enter through the cavity 12 and come into contact with the surface of the water pump, thereby achieving rapid cooling after the water pump is started. A wind guide device 5 is provided at the bottom of the inner wall of the cavity 12, so that when the airflow passes under the mounting base 1, the amount of air entering the cavity 12 is increased under the guidance of the wind guide device 5, thereby improving the cooling efficiency.

[0025] By setting up a squeezing device 4 and a clamping device 3, the clamping device 3 clamps the periphery of the water pump, thereby achieving the fixed installation of the water pump. During the installation process, by adjusting the height of the squeezing device 4, the top of the squeezing device 4 abuts against the bottom of the water pump. The change in the height of the squeezing device 4 can drive the change in the height of the water pump during installation, avoiding errors in the height of the water pump during installation and affecting the connection efficiency between the water pump and the water pipe.

[0026] A T-shaped block 32 is fixedly connected to the lower surface of the movable block 31. A T-shaped groove 13 that mates with the T-shaped block 32 is opened on the surface of the mounting base 1. An adjustment knob 34 is threadedly connected to the side of the mounting base 1. The end of the adjustment knob 34 extends into the T-shaped groove 13 and is rotatably connected to the T-shaped block 32.

[0027] Specifically, the cooperation between the T-shaped block 32 and the T-shaped groove 13 allows the movable block 31 to slide stably on the mounting base 1. The rotation of the adjusting knob 34, under the action of the thread, squeezes and drives the movable block 31 to move, thereby squeezing and fixing the water pump with the arc-shaped block 33.

[0028] The inner side of the arc-shaped block 33 is a rubber block with a frosted surface. The outer side of the arc-shaped block 33 is fixedly connected to a fixing rod 331. The end of the fixing rod 331 extends into the movable block 31 and is slidably connected to it. The buffer assembly includes a first spring 332 disposed in the movable block 31. The two ends of the first spring 332 are fixedly connected to the movable block 31 and the fixing rod 331, respectively.

[0029] Specifically, the rubber block deforms under pressure, increasing the contact area with the water pump and thus securing it stably. The buffer component cushions the pressure when it is too high, preventing damage to the pump's casing.

[0030] The mounting base 1 has fixed feet 11 fixedly connected to the lower surface of each of the four corners. The lower surface of the fixed feet 11 is provided with a buffer pad 2. The lower surface of the fixed feet 11 has several insertion holes 111. The upper surface of the buffer pad 2 is fixedly connected with multiple plug rods 21 that are inserted into the insertion holes 111.

[0031] Specifically, the fixed foot 11 is fixedly connected to the drainage and flood control vehicle by bolts. The buffer pad 2 is designed to buffer the vibration force when the mounting base 1 is subjected to vibration, and can also absorb the noise generated during vibration to a certain extent. The design of the plug rod 21 and the plug hole 111 allows the buffer pad 2 to be conveniently connected to the fixed foot 11, avoiding displacement of the buffer pad 2 during installation.

[0032] The air guide plate is fixedly connected to the mounting base 1 via the connecting plate 51. Several baffles 52 are fixedly connected to the periphery of the air guide plate. The extrusion device 4 includes an adjusting bolt 41 threadedly connected to the lower surface of the air guide plate, and the end of the adjusting bolt 41 penetrates the air guide plate.

[0033] Specifically, the baffle 52 can gather the air passing around the air guide plate, thereby increasing the efficiency of airflow entering the cavity 12. The adjusting bolt 41 rotates, and under the action of the thread, it drives the adjusting bolt 41 to move up and down, and abuts against the bottom of the water pump.

[0034] An extrusion pad 42 is provided above one end of the adjusting bolt 41 that passes through the air guide plate. A plug rod 421 is fixedly connected to the lower surface of the extrusion pad 42. The bottom end of the plug rod 421 is slidably inserted into the adjusting bolt 41. A second spring 43 is provided inside the adjusting bolt 41. The two ends of the second spring 43 are fixedly connected to the adjusting bolt 41 and the plug rod 421, respectively.

[0035] Specifically, the compression pad 42 contacts the bottom of the water pump, and the design of the second spring 43 allows it to absorb the compression force on the compression pad 42, preventing excessive compression force from damaging the bottom housing of the water pump.
