Description

Technical Field

[0001] The present invention relates to the technical field of seepage grouting, and particularly to a seepage grouting device for a dam. Background Art

[0002] Dam seepage refers to the seepage phenomenon in which water passes through the dam body, dam foundation, and around the dam on both sides due to the action of water pressure load and the water level difference between the upstream and downstream in the dam project. When seepage occurs in the dam, a grouting device can be used for plugging.

[0003] However, during the use of the existing grouting device, the slurry in the slurry bucket is sent out under high pressure through the grouting device and accurately conveyed through the grouting pipe for grouting. However, when some of the slurry is not completely stirred evenly, it will cause blockage in the grouting pipe during the conveying process, and subsequent cleaning is quite troublesome. In severe cases, it is necessary to directly replace it, resulting in cost losses. Summary of the Invention

[0004] The purpose of the present invention is to provide a seepage grouting device for a dam to solve the problem of blockage in the grouting pipe during the conveying process when some of the slurry is not completely stirred evenly as proposed in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A seepage grouting device for a dam, comprising:

[0006] A grouting machine, with a stirring and filtering assembly arranged above the grouting machine;

[0007] The stirring and filtering assembly includes a slurry bucket, with a bucket cover arranged above the slurry bucket. A support plate is arranged on the inner wall of the slurry bucket near the upper part. An air motor is fixedly installed above the middle of the support plate. The input end of the air motor is fixedly connected with a connecting pipe, and the output end of the air motor is fixedly connected with a driving rod. A limiting rod is connected to the outer wall of the middle of the driving rod. Blades are fixedly arranged on the lower outer wall of the driving rod. An outer frame is inserted through the lower part of the inner side of the slurry bucket. A filter screen is fixedly installed on the lower part of the inner wall of the outer frame. A side plate is fixedly arranged on one side of the outer frame. Rubber gaskets are fixedly arranged on the upper and lower sides of the side plate. The outer side of the side plate abuts against a limiting plate. A shaft rod penetrates through the upper part of the limiting plate. One end of the shaft rod is fixedly installed on a fixed block. A slider abuts against the upper part of the limiting plate. The slider is connected to the fixed block through a spring.

[0008] Preferably, the slurry bucket is installed on the grouting port of the grouting machine, and the bucket cover is provided with a hole corresponding to the size of the connecting pipe.

[0009] Preferably, the support plate is fixedly connected to the slurry bucket, and the end of the connecting pipe away from the air motor is fixedly installed in the high-pressure air supply pipe of the grouting machine.

[0010] Preferably, the driving rod is rotatably connected to the support plate and the limiting rod respectively, and the limiting rod is fixedly connected to the slurry bucket.

[0011] Preferably, the slurry bucket is provided with a groove corresponding to the size of the outer frame, and the outer frame is slidably connected to the slurry bucket.

[0012] Preferably, the upper surface of the filter screen is lower than the upper surface of the outer frame, and a holding hole is provided inside the side plate.

[0013] Preferably, the limiting plate is rotatably connected to the shaft rod, and the fixing block is fixedly connected to the slurry bucket.

[0014] Preferably, the fixing block is provided with a groove corresponding to the slider, and the slider is slidably connected to the fixing block. Both ends of the spring are fixedly connected to the fixing block and the slider respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] For the grouting device of the present invention, by setting the stirring and filtering assembly, open the bucket cover, pour the previously stirred slurry into the slurry bucket, close the bucket cover, start the grouting machine, and part of the high-pressure gas in the air supply pipe of the grouting machine enters the pneumatic motor. The output end of the pneumatic motor drives the driving rod to rotate, and the driving rod drives the paddle to rotate. The paddle can perform a final stirring on the slurry about to be sent out in the slurry bucket. The slurry about to be sent out also needs to pass through the filter screen for filtration to prevent some still unevenly stirred slurry from entering the grouting pipe of the grouting machine and avoid clogging in the grouting pipe of the grouting machine, ensuring that the slurry entering the grouting pipe of the grouting machine can smoothly complete grouting. After grouting, the slider can be pressed into the fixing block, the spring is compressed, the limiting plate is rotated upward around the shaft rod, and no longer presses against the side plate. Hold the holding hole of the side plate and pull out the side plate together with the outer frame from the slurry bucket, which is convenient for cleaning the slurry on the filter screen and the operation is fast.

Detailed implementation manners

[0024] Please refer to Figures 1-6 , an embodiment provided by the present invention: a dam seepage grouting device. The grouting machine 01 and the pneumatic motor 24 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0025] Including: a grouting machine 01, and a mixing and filtering component 02 is arranged above the grouting machine 01;

[0026] The stirring and filtering assembly 02 includes a slurry barrel 21. Above the slurry barrel 21, there is a barrel cover 22. Inside the slurry barrel 21, a support plate 23 is provided near the upper part. The support plate 23 supports the pneumatic motor 24. Above the middle of the support plate 23, a pneumatic motor 24 is fixedly installed. The pneumatic motor 24 provides power. After the pneumatic motor 24 is started, it can drive the drive rod 26 to rotate. The input end of the pneumatic motor 24 is fixedly connected to a connecting pipe 25, and the output end of the pneumatic motor 24 is fixedly connected to a drive rod 26. A limiting rod 27 is connected to the outer wall in the middle of the drive rod 26. The limiting rod 27 can guide the drive rod 26 to ensure the stability of the rotation of the drive rod 26. On the lower outer wall of the drive rod 26, a paddle 28 is fixedly provided. The paddle 28 performs the final stirring and leveling of the slurry about to be sent out in the slurry barrel 21. An outer frame 29 is inserted near the lower part inside the slurry barrel 21. The outer frame 29 together with the filter screen 30 can be pulled out of the slurry barrel 21 to clean the slurry on the filter screen 30. Inside the lower part of the inner wall of the outer frame 29, a filter screen 30 is fixedly installed. The filtered slurry can be located on the filter screen 30. When the outer frame 29 together with the filter screen 30 is pulled out of the slurry barrel 21, the slurry barrel 21 will not squeeze down the slurry on the filter screen 30. On one side of the outer frame 29, a side plate 31 is fixedly provided. Hold the holding hole of the side plate 31 and pull out the side plate 31 together with the outer frame 29 from the slurry barrel 21 for cleaning. Rubber gaskets 32 are fixedly provided on the upper and lower sides of the side plate 31. The rubber gaskets 32 play a role in enhancing the seal and preventing the slurry in the slurry barrel 21 from leaking. An outer limiting plate 33 abuts against the outside of the side plate 31. The outer limiting plate 33 can abut against the outside of the side plate 31 to limit the side plate 31. After the outer limiting plate 33 is rotated upward around the outer limiting plate 33, the side plate 31 together with the outer frame 29 can be pulled out of the slurry barrel 21. A shaft rod 34 penetrates through the upper part inside the outer limiting plate 33. One end of the shaft rod 34 is fixedly installed on a fixed block 35. The fixed block 35 plays a role in guiding and limiting the slider 36. The slider 36 abuts against the upper part of the outer limiting plate 33. The slider 36 can be pressed into the fixed block 35, and the spring 37 is compressed. Rotate the outer limiting plate 33 upward around the shaft rod 34 so that it no longer abuts against the side plate 31. Hold the holding hole of the side plate 31 and pull out the side plate 31 together with the outer frame 29 from the slurry barrel 21, which is convenient for cleaning the slurry on the filter screen 30. The slider 36 is connected to the fixed block 35 through the spring 37. The spring 37 provides elastic force. Under the elastic force of the spring 37, the slider 36 pops out of the fixed block 35 and abuts against the upper part of the outer limiting plate 33, which can limit the outer limiting plate 33, and further ensure that the outer limiting plate 33 limits the side plate 31.

[0027] Further, the slurry barrel 21 is installed on the grouting port of the grouting machine 01. The slurry in the slurry barrel 21 can enter the grouting pipe of the grouting machine 01 through the grouting port of the grouting machine 01 under high pressure. The barrel cover 22 is provided with a hole corresponding to the size of the connecting pipe 25 to ensure that the barrel cover 22 does not affect the normal use of the connecting pipe 25.

[0028] Furthermore, the support plate 23 is fixedly connected to the slurry barrel 21 to ensure the firmness of the position of the support plate 23. The support plate 23 plays a role in supporting the pneumatic motor 24. One end of the connecting pipe 25 away from the pneumatic motor 24 is fixedly installed in the high-pressure air supply pipe of the grouting machine 01. After starting the grouting machine 01, a part of the high-pressure gas in the air supply pipe of the grouting machine 01 can enter the pneumatic motor 24, causing the pneumatic motor 24 to start.

[0029] Furthermore, the drive rod 26 is rotatably connected to the support plate 23 and the limit rod 27 respectively to ensure that neither the support plate 23 nor the limit rod 27 affects the rotation of the drive rod 26. The rotation of the drive rod 26 can drive the paddle 28 to rotate. The paddle 28 performs a final stirring and leveling of the slurry about to be sent out in the slurry barrel 21. The limit rod 27 is fixedly connected to the slurry barrel 21 to ensure the firmness of the position of the limit rod 27. The limit rod 27 can guide the drive rod 26 and ensure the stability of the rotation of the drive rod 26.

[0030] Furthermore, the slurry barrel 21 is provided with a groove corresponding to the size of the outer frame 29, and the outer frame 29 is slidably connected to the slurry barrel 21. The outer frame 29 together with the filter screen 30 can be pulled out of the slurry barrel 21 to clean the slurry on the filter screen 30.

[0031] Furthermore, the upper surface of the filter screen 30 is lower than the upper surface of the outer frame 29 to ensure that the filtered slurry can be located on the filter screen 30. When the outer frame 29 together with the filter screen 30 is pulled out of the slurry barrel 21, the slurry barrel 21 will not squeeze the slurry on the filter screen 30 down. A holding hole is provided inside the side plate 31, which facilitates holding the holding hole of the side plate 31 and pulling out the side plate 31 together with the outer frame 29 from the slurry barrel 21 for cleaning.

[0032] Furthermore, the limit plate 33 is rotatably connected to the shaft rod 34. The limit plate 33 can abut against the outside of the side plate 31 to limit the side plate 31. After the limit plate 33 is rotated upward around the limit plate 33, the side plate 31 together with the outer frame 29 can be pulled out of the slurry barrel 21. The fixing block 35 is fixedly connected to the slurry barrel 21 to ensure the firmness of the position of the fixing block 35. The fixing block 35 plays a role in guiding and limiting the slider 36.

[0033] Further, the fixing block 35 is provided with a groove corresponding to the sliding block 36, and the sliding block 36 is slidably connected to the fixing block 35. The sliding block 36 can be pressed into the fixing block 35, the spring 37 is compressed, the limiting plate 33 is rotated upward around the shaft rod 34, and no longer abuts against the side plate 31. Hold the holding hole of the side plate 31 and pull out the side plate 31 together with the outer frame 29 from the slurry bucket 21, which is convenient for cleaning the slurry on the filter screen 30. The two ends of the spring 37 are respectively fixedly connected to the fixing block 35 and the sliding block 36. The spring 37 provides elastic force. Under the action of the elastic force of the spring 37, the sliding block 36 pops out of the fixing block 35 and abuts above the limiting plate 33, so as to limit the limiting plate 33, and further ensure that the limiting plate 33 limits the side plate 31.

[0034] Working principle: When in use, first open the bucket cover 22, pour the pre-stirred slurry into the slurry bucket 21, close the bucket cover 22, and start the grouting machine 01. Part of the high-pressure gas in the air supply pipe of the grouting machine 01 enters the pneumatic motor 24. The output end of the pneumatic motor 24 drives the driving rod 26 to rotate, and the driving rod 26 drives the paddle 28 to rotate. The paddle 28 can perform the final stirring on the slurry to be sent out in the slurry bucket 21. The slurry to be sent out still needs to pass through the filter screen 30 for filtration. After the grouting is completed, the sliding block 36 can be pressed into the fixing block 35, the spring 37 is compressed, the limiting plate 33 is rotated upward around the shaft rod 34, and no longer abuts against the side plate 31. Hold the holding hole of the side plate 31 and pull out the side plate 31 together with the outer frame 29 from the slurry bucket 21 for cleaning.
