[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0033] like Figures 1 to 11The self-balancing super-large sand pumping machine shown comprises a shell 2, a pump shell 1 fixedly connected to the bottom of the shell 2, a cavity 18 formed in the pump shell 1, a ring cavity 11 formed in the sidewall of the shell 2, rust-proof liquid injected into the ring cavity 11, the ring cavity 11 being in communication with the cavity 18, a sliding ring 12 slidably connected to the ring cavity 11, a ring-shaped folding air bag 3 in communication with the top of the ring cavity 11, the folding air bag 3 being in communication with the ring cavity 11 and the communication position being above the sliding ring 12, a feeding port 33 in communication with the bottom of the pump shell 1, and a blocking prevention assembly provided at the bottom of the feeding port 33 and used for dispersing the silt.

[0034] In the embodiment, the sand pumping machine is a silt mixed slurry pump used for conveying the suspension liquid containing sand particles and slag. In the use process, the sand pumping machine generates a large flow and a large pressure in the working process. The conventional sand pumping machine relies on increasing the thickness of the pump shell 1 and using a material with high hardness to resist the high pressure in the pump cavity.

[0035] In the use process of the sand pumping machine, the gas in the folding air bag 3 is extracted into the ring cavity 11 to increase the air pressure in the ring cavity 11. After the air pressure is increased, the gas pressure is used to push the sliding ring 12 to slide downward, so that the sliding ring 12 extrudes the rust-proof liquid in the ring cavity 11 and extrudes the rust-proof liquid into the cavity 18. After the rust-proof liquid enters the cavity 18, the pressure in the cavity 18 is increased. The high-pressure water is injected into the cavity 18, so that the pressure inside and outside the pump shell 1 is consistent, thereby offsetting the pressure of the high-pressure water in the pump cavity on the pump shell 1, achieving the purpose of self-balancing, and enabling the sand pumping machine to resist the high-pressure impact of water.

[0036] The high-pressure water is injected into the cavity 18. In the working process of the sand pumping machine, the flexibility of water can play a certain damping effect on the sand pumping machine. The dispersing assembly at the bottom of the sand pumping machine can also play a certain damping effect in the working process of the sand pumping machine.

[0037] In the process of placing the sand pumping machine into water, the gas in the folding air bag 3 can make the weight of the bottom of the sand pumping machine higher than the weight of the top. In the process of descending, the folding air bag 3 will bear a certain buoyancy. The buoyancy can make the sand pumping machine always sink vertically. After sinking to the bottom of the water, the gas in the folding air bag 3 is inflated into the ring cavity 11, so that the rust-proof liquid in the ring cavity 11 enters the cavity 18.

[0038] After the gas in the folded air bag 3 enters the ring cavity 11, the folded air bag 3 is reduced, and the buoyancy of the sand pump is reduced, so that the sand pump can effectively sink to the bottom of the river, and the sand pump can effectively contact the sand at the bottom of the river during the use of the sand pump to extract sand from the bottom of the river, and the existence of the folded air bag 3 can avoid the situation that the sand pump is suspended in the water.

[0039] After the sand pump is finished, the gas in the ring cavity 11 is re-inflated into the folded air bag 3, so that the folded air bag 3 is inflated, the buoyancy of the sand pump is increased, and the sand pump is convenient for technicians to recover.

[0040] By arranging the cavity 18, on the one hand, the thickness of the pump shell 1 is reduced, the pump shell 1 is made into a double-layer structure, and high-pressure water is introduced into the cavity 18, so that the pressure inside and outside the pump shell 1 is consistent, and the pressure of the high-pressure water in the pump cavity on the pump shell 1 is offset, achieving a self-balancing purpose. This design reduces the thickness of the pump shell 1, reduces the use of materials, and reduces the overall weight of the pump. On the other hand, the design of the pump shell 1 can not use high-hardness materials. Since the pressure inside and outside the pump shell 1 is balanced, ordinary materials can meet the requirements, reducing production costs and improving market competitiveness.

[0041] As a further embodiment of the present application, the top of the pump shell 1 is provided with a sealing ring 15, the side of the sealing ring 15 away from the pump shell 1 is fixedly connected with the shell 2, the sealing ring 15 is used for sealing between the pump shell 1 and the shell 2, the bottom of the sealing ring 15 is provided with a ring-shaped sealing air bag 16, the sealing air bag 16 is communicated with the ring cavity 11, the sealing air bag 16 movably abuts against the top wall plate of the side of the pump shell 1, the bottom of the ring cavity 11 is communicated with a plurality of pressurized water pipes 17, the plurality of pressurized water pipes 17 penetrate the wall plate of the shell 2 and the pump shell 1 and are communicated with the cavity 18, and the communication part of the pressurized water pipe 17 with the ring cavity 11 is provided with an electric control valve.

[0042] In specific implementation, through the arrangement of the sealing ring 15, the shell 2 and the pump shell 1 can be effectively sealed. During the process of inflating the gas in the folded air bag 3 into the ring cavity 11, part of the gas entering the ring cavity 11 will enter the sealing air bag 16 at the bottom of the sealing ring 15, so that the sealing air bag 16 is inflated. After the sealing air bag 16 is inflated, it abuts against the wall plate at the top of the side of the cavity 18. On the one hand, it can further prevent water from entering between the pump shell 1 and the shell 2, and improve the sealing performance of the sealing ring 15. On the other hand, it can also convert part of the vibration energy into internal energy generated by the collision between the gases during the process of conveying the silt by the pump shell 1, so as to achieve the purpose of reducing the vibration of the device and play the auxiliary damping role.

[0043] In the process of inflating the gas in the folding air bag 3 into the ring cavity 11, the electric control valve is opened, the rust-proof liquid in the ring cavity 11 is pressed into the cavity 18, the water pressure in the cavity 18 is increased, and the purpose of improving the pressure resistance of the pump shell 1 is achieved.

[0044] As a further embodiment of the present application, a plurality of external conduits 4 are fixedly connected to the top of the sealing ring 15, one end of the external conduit 4 away from the sealing ring 15 is fixedly connected to the shell 2, and the other end of the external conduit 4 is in communication with the sealing air bag 16 and the ring cavity 11, respectively. The external conduit 4 is used to supply air to the sealing air bag 16, and when the sliding ring 12 is at the uppermost position in the hard ring cavity 11, the communication position of the external conduit 4 with the ring cavity 11 is above the sliding ring 12.

[0045] In specific implementation, through the arrangement of the external conduit 4, in the process of inflating the gas in the folding air bag 3 into the ring cavity 11, part of the gas entering the ring cavity 11 will enter the sealing air bag 16 through the external conduit 4, and then the sealing air bag 16 will be inflated.

[0046] Secondly, the external conduit 4 can also form a barrier-like protection on the outside of the shell 2, which is beneficial to protect the shell 2 and avoid damage to the motor 20 inside the shell 2 due to external impact, and can also play a certain protective role for the ring cavity 11, which is beneficial to avoid the ring cavity 11 from being dented due to impact, thereby preventing the sliding ring 12 from being unable to slide in the ring cavity 11.

The lowermost partition ring 30 is fixedly connected to the upper side of the sliding ring 12 through the plurality of connecting columns 28 at the bottom of the lowermost partition ring 30. A plurality of abutting columns 29 are fixedly connected to the top of the uppermost partition ring 30, the plurality of abutting columns 29 are in movable abutment with the top wall plate of the ring cavity 11, and when the abutting columns 29 abut with the top wall plate of the ring cavity 11, the connection position of the external conduit 4 with the ring cavity 11 is above the uppermost partition ring 30.

[0048] In specific implementation, through the arrangement of the plurality of partition rings 30, it is beneficial to avoid the rust-proof liquid in the ring cavity 11 from entering the upper side of the sliding ring 12, and secondly, the plurality of partition rings 30 can also support the communication position of the external conduit 4 with the ring cavity 11 during the non-use of the sand pump, which is beneficial to avoid the dent of the connection position of the external conduit 4 with the ring cavity 11 due to impact.

[0050] In the specific implementation, in the process of inflating the gas in the folded air bag 3 into the annular cavity 11, the high-pressure air pump 13 is started to inflate the gas in the folded air bag 3 into the annular cavity 11, and in this process, the electromagnetic valve 14 is always kept open. After the gas enters the annular cavity 11, part of the gas enters the sealed air bag 16 through the external conduit 4, thereby enabling the sealed air bag 16 to effectively seal between the shell 2 and the pump shell 1.

[0051] It should be noted that the high-pressure air pump 13 is a bidirectional air pump. When it is necessary to recover the device, the high-pressure air pump 13 is controlled to supply air in the reverse direction, so that the high-pressure air pump 13 extracts the gas in the annular cavity 11 into the folded air bag 3, so that the folded air bag 3 expands, thereby increasing the displacement of the device, increasing the buoyancy of the device by increasing the displacement, and thereby achieving the purpose of facilitating the recovery of the device. In the process of working of the high-pressure air pump 13, the electromagnetic valve 14 and the electric control valve are both in the open state.

[0053] In the specific implementation, in the process of working of the sand pumping pump, when the mud and sand mixed slurry is mixed with clumps, the impact of the water flow will drive the elastic tabs 23 to vibrate, the vibration of the elastic tabs 23 will knock the mud and sand mixed slurry in the water, thereby being able to scatter the mud and sand mixed slurry, on the one hand, avoiding the pipe blockage in the subsequent conveying process due to the clumping of the mud and sand mixed slurry, and on the other hand, also being conducive to avoiding the damage of the impeller 19 caused by the impact of the clumped mud and sand mixed slurry on the impeller 19.

[0057] In specific implementation, the setting of the cleaning mechanism can clean the magazines on the conical ring filter screen 6 during the operation of the device, which is beneficial to avoid the plugging of the conical ring filter screen 6. The elastic member 21 can be preferably a third spring, and the elasticity of the third spring is used to make the brush 22 contact the conical ring filter screen 6.

[0058] As a further implementation of the present application, a plurality of sliding holes are formed in the beating ring 9, a plurality of connecting rods 31 are slidingly sleeved in the plurality of sliding holes respectively, a plurality of prefabricated holes are further formed in the beating ring 9, the diameter of the prefabricated hole is greater than the diameter of the sleeve 24, a plurality of sleeves 24 are located in the plurality of prefabricated holes respectively, a plurality of second springs 27 are fixedly connected with the top and the bottom of the beating ring 9 respectively, the plurality of second springs 27 above the beating ring 9 are in movable abutment with the fixed ring 8, and the plurality of second springs 27 below the beating ring 9 are in movable abutment with the top wall plate of the bottom plate 10.

[0060] As a further embodiment of the present application, the inside of the shell 2 is provided with a motor 20, the output shaft of the motor 20 extends into the pump shell 1, the impeller 19 is rotatably connected in the pump shell 1, the output shaft of the motor 20 is fixedly connected with the impeller 19, and the motor 20 is used to drive the impeller 19 to rotate, the top of the shell 2 is fixedly connected with a wire 32 for supplying power to the motor 20, the wire 32 penetrates through the shell 2 and is electrically connected with the motor 20, and a sealing ring is arranged at the connection between the wire 32 and the shell 2, and the side of the pump shell 1 is communicated with the discharge port 5.

[0061] In the specific implementation, during use of the device, the motor 20 is powered through the wire 32, and the sludge mixed slurry is transported through the rotation of the impeller 19.

[0062] The working principle of the present application is as follows:

[0063] In use, first, the device is placed in water, and in this process, the folded air bag 3 is in an inflated state, the inflation of the folded air bag 3 causes the device to be subjected to a certain buoyancy of water, thereby enabling the device to maintain a vertical state for descending, and thereby enabling the bottom plate 10 to contact the ground of the water bottom, facilitating the device to extract the sludge mixed slurry from the water bottom.

[0064] In the process of contacting the ground of the water bottom by the bottom plate 10, the first spring 26 is arranged to effectively buffer the device, avoiding the device from sinking into the silt of the water bottom due to excessive falling speed, thereby causing the heat dissipation of the motor 20 to be affected, and secondly, by avoiding the device from sinking deeply into the silt, the device can be easily recovered from the water, avoiding the situation that the device cannot be taken out from the water bottom due to silt adhesion, and the folded air bag 3 promotes each other, making the device more convenient to recover in water.

[0065] In the process of placing the device in water, if the device cannot normally descend due to the buoyancy of the folded air bag 3, the high-pressure air pump 13 is turned on to reduce the gas content in the folded air bag 3, thereby reducing the displacement of the device, so that the device can normally fall.

[0066] After the motor 20 is started, the impeller 19 is driven to rotate by the output shaft of the motor 20, so that the impeller 19 extracts the sludge mixed slurry through the feed port 33. In the process of liquid flow, the liquid will impact on the beating ring 9, and the water flow will drive the beating ring 9 to vibrate. Through the vibration of the beating ring 9, the second spring 27 is vibrated. In the process of vibration of the second spring 27, the second spring 27 can disperse the sludge agglomerates in the liquid, and can also adsorb and filter the flocculent impurities. After the liquid enters below the feed port 33, the elastic flap 23 can be arranged to disperse the sludge agglomerates in the liquid which are not dispersed by the second spring 27 for the second time, effectively improving the dispersion degree of the sludge, which is beneficial to avoid damage to the impeller 19 due to incomplete dispersion of the sludge, and can also avoid the situation that the subsequent conveying pipeline is blocked due to the agglomeration of the sludge.

[0067] When the space between the fixed ring 8 and the bottom plate 10 is blocked, the impeller 19 will idle. Through the arrangement of the conical ring filter screen 6, when the space between the fixed ring 8 and the bottom plate 10 is blocked, the liquid can enter the feed port 33 through the filter holes of the conical ring filter screen 6, so that the feed port 33 can effectively extract the liquid, which is beneficial to avoid the idle of the impeller 19 due to the blocking of the space between the fixed ring 8 and the bottom plate 10, and can also avoid the negative pressure in the pump shell 1. Through the arrangement of the conical ring filter screen 6, to a certain extent, the motor 20 can be protected from being burned out due to the idling of the impeller 19.

[0068] During the operation of the motor 20, after the liquid is extracted into the feed port 33, the device has a downward movement trend. The first spring 26 can effectively dampen and buffer the downward movement trend of the device. In this process, the pump shell 1 and the shell 2 move downward relative to the bottom plate 10. In this process, due to the existence of the connecting rod 31, the movable ring 7 moves upward relative to the pump shell 1 and the shell 2, so that the movable ring 7 drives the brush 22 to clean the conical ring filter screen 6, which is beneficial to avoid the idling of the impeller 19 due to the blocking of the conical ring filter screen 6.

[0069] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
