Description

Technical Field

[0001] This utility model belongs to the field of water conservancy construction technology, specifically relating to a soil compaction device for water conservancy construction. Background Technology

[0002] Soil compaction devices used in water conservancy construction can significantly reduce soil porosity and increase soil density through external force, forming a continuous and dense layer on the construction base surface that can effectively block water infiltration and improve the compressive and shear strength of the foundation, thus ensuring the long-term stable operation of water conservancy facilities.

[0003] Chinese patent document CN222120186U discloses a soil compactor for water conservancy projects. The device uses rotating fan blades in conjunction with a guide tube to draw dust generated by compacting soil below the device into the guide tube and send it into an air washing box through an air pipe, thereby avoiding dust pollution of the environment and posing a threat to the occupational health of operators.

[0004] However, in the existing technology, the method of sucking dust into the compactor by rotating the fan, and then lifting and collecting the dust is simple and easily causes a large amount of dust to accumulate in the dust conveying channel of the device. Therefore, a soil compaction device for water conservancy construction is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a soil compaction device for water conservancy construction.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A soil compaction device for water conservancy construction includes a movable component that allows workers to easily move the device to the required location, a compaction component that can continuously impact the soil to compact it, and a dust suppression component that can effectively suppress dust generation on the compaction component.

[0008] The moving components include the chassis;

[0009] The compaction assembly includes a guide tube that is fixedly installed within the vehicle frame;

[0010] The dust suppression assembly includes a dust suppression component that can suppress dust generation by combining spraying droplets with suction, and a liquid supply component that can store dust suppression liquid and inject it into the dust suppression component;

[0011] The dust suppression component includes multiple Venturi tubes fixedly connected to the outer side of the guide tube. An atomizing nozzle is fixedly connected to the end of the Venturi tube away from the guide tube. A ring frame fixedly connected to the guide tube is provided above the Venturi tube. A suction pipe is fixedly connected between the ring frame and the suction end of the Venturi tube.

[0012] Preferably, the liquid supply component includes a diverter pipe fixedly connected to the tail end of the atomizing nozzle, a diverter connector fixedly connected to the upper end of the diverter pipe, a liquid tank fixedly installed above the vehicle frame, a pump fixedly connected to the liquid outlet end of the liquid tank, and an injection pipe fixedly connected between the liquid outlet end of the pump and the diverter connector.

[0013] Preferably, multiple venturi tubes are arranged at equal angular intervals around the center line of the guide cylinder.

[0014] Preferably, the lower side of the ring frame is integrally formed with through grooves, and the number of through grooves is the same as that of the venturi tubes.

[0015] Preferably, the inner surface of the venturi tube is provided with a hydrophobic coating.

[0016] Preferably, the compaction assembly further includes a cover plate fixedly connected to the top of the guide cylinder, multiple uprights fixedly connected inside the guide cylinder, springs movably connected to the outer side of the uprights, a U-shaped frame movably connected to the uprights above the springs, a pressure block fixedly connected to the lower side of the U-shaped frame, a transmission frame fixedly connected above the pressure block, a roller movably mounted on the upper end of the transmission frame, a motor fixedly mounted inside the frame, a coupling fixedly connected to the output end of the motor, a reducer fixedly connected in front of the coupling, and a cam fixedly connected to the output end of the reducer above the roller.

[0017] Preferably, both the spring and the U-shaped frame are slidably connected to the upright.

[0018] The beneficial effects of this utility model are as follows: By setting multiple Venturi tubes, each connected to an atomizing nozzle, on the guide tube, this device can, when dust is generated, simply supply liquid with a certain pressure to the atomizing nozzle to appropriately wet the dust particles within the coverage area of ​​the guide tube, making them difficult to be stirred up. Dust particles that have escaped outside the main body of the guide tube are sucked in by the Venturi tube along the suction pipe and the ring frame and then discharged. Thus, this device can effectively suppress dust generation without the need to collect dust particles. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] like Figures 1-6 As shown, a soil compaction device for water conservancy construction includes a movable component 1 that allows workers to easily move the device to the required location. The movable component 1 is equipped with a compaction component 2 that can continuously impact the soil to compact it. The compaction component 2 is equipped with a dust suppression component 3 that can effectively suppress dust generation.

[0032] In this embodiment: the mobile component 1 includes a frame 101, a roller 102 is fixedly installed under the frame 101, an inspection plate 103 is fixedly connected to both sides of the frame 101, and a pusher 104 is fixedly connected to the top of the frame 101.

[0033] The frame 101 provides mounting positions for components such as rollers 102, guide cylinders 201, and liquid tanks 307. The push frame 104 makes it easy for workers to move the frame 101 with rollers 102 installed. The inspection plate 103 provides protection for the components installed inside the frame 101. After the inspection plate 103 is removed from the frame 101, workers can easily inspect and maintain these components.

[0034] In this embodiment: the compaction component 2 includes a guide cylinder 201 fixedly installed inside the frame 101. The compaction component 2 also includes a cover plate 202 fixedly connected above the guide cylinder 201. Multiple uprights 203 are fixedly connected inside the guide cylinder 201. A spring 204 is movably connected to the outer side of the uprights 203. A U-shaped frame 205 is provided above the spring 204 and movably connected to the uprights 203. A pressure block 206 is fixedly connected to the lower side of the U-shaped frame 205. A transmission frame 207 is fixedly connected above the pressure block 206. A roller 208 is movably installed at the upper end of the transmission frame 207. A motor 209 is fixedly installed inside the frame 101. A coupling 210 is fixedly connected to the output end of the motor 209. A reducer 211 is fixedly connected to the front of the coupling 210. A cam 212 is provided above the roller 208 and fixedly connected to the output end of the reducer 211.

[0035] Spring 204 and U-shaped frame 205 are both slidably connected to upright 203;

[0036] The guide cylinder 201 provides installation positions for components such as the upright 203, venturi tube 301, and ring frame 303. The cover plate 202 leaves only an area for the transmission frame 207 to pass through the top of the guide cylinder 201. The pressure block 206 is installed in the guide cylinder 201 through the U-shaped frame 205, which is guided and limited by the upright 203 and spring 204. The spring 204 can overcome the weight of the pressure block 206 and other components, and the transmission frame 207 connected to the pressure block 206 tends to drive the roller 208 to move towards the cam 212. The rotation of the motor 209 output end is reduced and increased in torque and its direction is changed through the coupling 210, reducer 211, cam 212, and roller 208 and then transmitted to the transmission frame 207, so that the transmission frame 207 can work with the spring 204 to make the pressure block 206 swing up and down smoothly.

[0037] In this embodiment: the dust suppression component 3 includes a dust suppression element that can suppress dust generation by combining spraying droplets with suction, and a liquid supply element that can store dust suppression liquid and inject it into the dust suppression element;

[0038] The dust suppression component includes multiple Venturi tubes 301 fixedly connected to the outer side of the guide tube 201. An atomizing nozzle 302 is fixedly connected to the end of the Venturi tube 301 away from the guide tube 201. A ring frame 303 fixedly connected to the guide tube 201 is provided above the Venturi tube 301. A suction pipe 304 is fixedly connected between the ring frame 303 and the suction end of the Venturi tube 301. The liquid supply component includes a diverter pipe 305 fixedly connected to the tail end of the atomizing nozzle 302. A diverter connector 306 is fixedly connected to the upper end of the diverter pipe 305. A liquid tank 307 is fixedly installed above the frame 101. A pump 308 is fixedly connected to the liquid outlet end of the liquid tank 307. An injection pipe 309 is fixedly connected between the liquid outlet end of the pump 308 and the diverter connector 306.

[0039] Multiple Venturi tubes 301 are arranged at equal angles around the center line of the guide cylinder 201. The lower side of the ring frame 303 is integrally formed with a through groove. The number of through grooves is the same as that of the Venturi tubes 301. The inner side of the Venturi tubes 301 is provided with a hydrophobic coating.

[0040] The supplied liquid is atomized and sprayed out along the Venturi tube 301 through the atomizing nozzle 302 facing the outlet end of the Venturi tube 301. The atomized droplet jet, which accelerates the flow at the cross-sectional area contraction of the Venturi tube 301, creates a low pressure at the suction end of the Venturi tube 301, which can draw in air from the ring frame 303 along the suction pipe 304. The liquid in the liquid tank 307 is pumped out by the operation of the pump 308, and after appropriate pressurization, it is pumped to the diversion joint 306 along the injection pipe 309. The liquid pumped into the diversion joint 306 can enter the respective connected atomizing nozzles 302 along the diversion pipes 305 in each direction through the diversion joint 306.

[0041] Working principle: When this device is installed for soil compaction in water conservancy construction, it is moved to the required position by the pusher frame 104, and then the motor 209 is run. After running, the motor 209 can drive the pressure block 206 located in the guide cylinder 201 to swing up and down through the coupling 210, reducer 211 and other components. After swinging, the pressure block 206 can continuously pound the soil below it to compact the soil.

[0042] If a large amount of dust is generated during the compaction process, the pump 308 can be run to pump the liquid in the liquid tank 307 into the atomizing nozzle 302, so that the liquid becomes atomized droplets and is sprayed to different positions below the compaction block 206. In this way, by wetting the dust particles located within the coverage area of ​​the guide cylinder 201, the soil cannot be lifted up in large quantities to form a large-scale dust. As for the dust particles that can still drift outside the coverage area of ​​the guide tube 201, due to the flow of the atomized droplet jet in the venturi tube 301, the venturi tube 301 will continuously draw air from the ring frame 303 through the suction pipe 304. The low-pressure ring frame 303 will continuously draw air from the lower end of the guide tube 201 below the ring frame 303 through its through groove. Therefore, these dust particles that drift outside the range of the guide tube 201 will be drawn into the venturi tube 301 along the ring frame 303 and the suction pipe 304 under the suction action of the ring frame 303. After mixing with the atomized droplets sprayed from the atomizing nozzle 302, they will be sprayed below the up-and-down swinging pressure block 206.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
