[0003] About water conservancy and hydropower project construction:

[0004] Construction diversion: Construction diversion is the primary step in water conservancy project construction, including cofferdam engineering, determination of diversion design flow, selection of diversion scheme, etc. This stage requires ensuring effective control of water flow during construction to provide a dry construction environment for subsequent projects.

[0005] Blasting engineering: Blasting engineering is a commonly used technical means in earthwork excavation, including the use of drilling equipment, charge calculation, blasting method selection and safety control, etc. Reasonable blasting operation is of great significance to improving construction efficiency and reducing costs.

[0006] Foundation treatment: Foundation treatment is the key to ensure the safety and stability of hydraulic structures, involving rock foundation grouting, concrete anti-seepage wall construction, rock foundation anchoring technology, etc. These measures can enhance the bearing capacity and stability of the foundation.

[0007] Dam construction: Dam construction includes earth-rock dam engineering and concrete dam construction. Earth-rock dam construction needs to consider factors such as material field planning, earth and rock excavation and transportation machinery, and transportation roads; concrete dam construction needs to focus on aggregate field planning, formwork engineering, concrete preparation and transportation, and other links.

[0008] Underground structure construction: Underground structure construction, such as underground cavern engineering, involves horizontal tunnel excavation, vertical shaft and inclined shaft excavation, shotcrete support and other technologies. These construction activities need to complete the construction of underground structures efficiently while ensuring safety.

Effective construction management can ensure that the project proceeds smoothly as planned while controlling costs and quality.

[0010] Environmental protection: During the construction process, attention should also be paid to environmental protection, and necessary measures should be taken to reduce the impact on the surrounding environment, such as soil and water conservation, ecological protection, etc.

[0011] The core is: construction diversion, blasting engineering and foundation treatment;

[0012] In foundation treatment, rock foundation grouting is very important. Rock foundation grouting (referred to as bedrock grouting) is to press a fluid and gelling slurry into the pores (cracks) of the rock formation through a drilling grouting device according to a certain ratio requirement. After hardening and cementing, it forms stones to improve the strength and integrity of the bedrock and improve the impermeability of the bedrock.

[0013] At present, the stirring devices in water conservancy and hydropower projects are usually used to mix and stir two or more substances of the same type. However, if the fluid and gelling slurries are mixed using conventional mixing mixers for water conservancy and hydropower projects, there is a certain problem of insufficient mixing, that is, the gelling slurry cannot be fully mixed with the fluid slurry, and the gelling slurry becomes granular and is mixed in the fluid slurry. In view of this, the inventor proposes a construction equipment for water conservancy and hydropower projects. Summary of the invention

[0014] The purpose of the present invention is to solve the problem that fluid and gelling slurries cannot be fully mixed in the rock foundation pouring process in traditional water conservancy and hydropower projects.

[0015] In order to achieve the above object, the present invention provides the following basic scheme:

[0016] A construction equipment for water conservancy and hydropower engineering, comprising a mixing barrel, a driving rotating shaft arranged inside the mixing barrel, a mixing and stirring disk arranged on the driving rotating shaft in order from bottom to top, a stirring receiving member connected to a bearing of the driving rotating shaft, a filter disk coaxially connected to the driving rotating shaft, a feeding assembly connected to the bearing of the driving rotating shaft, and an end cover detachably connected to the mixing barrel, wherein a driving member is arranged on the driving rotating shaft;

[0017] The stirring and receiving part includes a stirring barrel and a receiving barrel. Stirring rods are arranged around the driving rotating shaft in the stirring barrel. The driving rotating shaft in the stirring barrel and the receiving barrel is a threaded shaft. The threaded shaft is threadedly connected to a lifting component that can close the intersection of the stirring barrel and the receiving barrel. The lifting component is provided with a forward and reverse controller electrically connected to the driving part. An extrusion sieve plate is arranged on the driving rotating shaft at the bottom of the mixing barrel, and a discharge port is arranged at the outer bottom of the mixing barrel.

[0018] The principles and effects of this basic solution are:

[0019] 1. Compared with the prior art, the device has a simple structure and an ingenious design. Based on the viscosity of the gelling slurry, which may lead to inaccurate proportions, a device is designed to preferentially prepare the gelling slurry. The original solvent of most gelling slurries is still water. Water and the raw materials of the gelling slurry are first prepared to form a gelling slurry, and then the fluid slurry is stirred and mixed.

[0020] 2. Compared with the prior art, in order to achieve sufficient mixing, a multiple filtering concept is designed. The multiple filtering concept first screens the raw materials of the gelling slurry to remove impurities of the non-gelling slurry raw materials in the raw materials of the gelling slurry, so as to facilitate subsequent mixing. Secondly, the gelling slurry cannot be screened after being fully mixed with the fluid slurry. Since impurities may remain due to sufficient mixing, in order to avoid such impurity residues, another filtering concept is designed at the outlet of the device, which uses filtering to block the residual impurities and screen them out, thereby improving the output quality of the slurry.

[0021] 3. Compared with the prior art, the present device makes full use of the stirring and mixing action, and reasonably utilizes the self-rotation action generated by the stirring and mixing to mix the gelling slurry with the fluid slurry. A lifting component is designed, and the self-rotation action and the matching controller are used to make the lifting component reciprocate up and down, so that the gelling slurry is brought up and mixed with the fluid slurry. This feature is slow mixing and gradual fusion. This design can reduce the phenomenon that the gelling slurry becomes granular and is mixed in the fluid slurry.

[0022] 4. Compared with the prior art, a lifting component is designed, and the self-rotation action and the matching controller are used to make the lifting component do up and down reciprocating motion, and then the stirring barrel and the receiving barrel are independently designed. The stirring barrel is used in conjunction with the reciprocating motion, and the lifting component is used to do up and down reciprocating motion, so that the stirring barrel and the receiving barrel are connected or disconnected. When connected, the stirring barrel and the receiving barrel produce a certain pressure change, which accelerates the mixing of the gelling slurry and the fluid slurry.

[0023] Furthermore, the bottom of the end cap is provided with an external thread, the inner side of the top of the mixing barrel is provided with an internal thread groove, the end cap and the mixing barrel are connected by threaded connection, a bearing plate is fixedly connected to the outer side of the bottom of the mixing barrel, a plurality of support columns are evenly fixedly connected around the bearing plate, and the free ends of the support columns are fixedly connected with rubber anti-skid pads, so as to realize the stable installation of the device and the quick installation and quick removal between the end cap and the mixing barrel.

[0024] Furthermore, the feed assembly includes a receiving groove, a material guide cylinder, a plurality of material guide tubes and a feed tray, one end of each of the material guide tubes is connected to the feed tray, the feed tray passes through the receiving groove and is located on the upper side of the end cover, the other end of the material guide tube is connected to the material guide cylinder, the bottom of the material guide cylinder is provided with an outlet, the outlet is located above the filter tray, and the material guide cylinder is connected to the driving rotating shaft through a bearing, so that the material flows through the material guide tube after feeding and then flows to the top of the filter tray.

[0025] Furthermore, the filter disc includes a disc body, a filter screen arranged on the filter disc, and a guide sliding column arranged on the outside of the disc body, the inner wall of the mixing barrel corresponding to the guide sliding column is provided with a guide groove, the guide sliding column is slidably connected to the guide groove, and the disc body is coaxially connected to the driving rotating shaft. This case adopts a gelling slurry raw material processing mode, that is, the raw materials and water in the gelling slurry are no longer mixed preferentially, and the particles are filtered first and then mixed with water later, so as to first remove impurities from the particle raw materials.

[0026] Furthermore, the driving member is a motor, the upper end of the driving rotating shaft passes through the material guide cylinder and is coaxially connected to the motor, and the forward and reverse controller is electrically connected to the motor.

[0027] Furthermore, the mixing barrel and the receiving barrel are integrally formed, the connection between the mixing barrel and the receiving barrel is rounded, a liquid inlet is installed with a liquid inlet pipe, the liquid inlet pipe is used to put in fluid slurry, and the height of the liquid inlet is higher than the height of the receiving barrel, so that the fluid slurry enters the receiving barrel from the top.

[0028] Furthermore, the lifting assembly includes a lifting block threadedly connected to the threaded shaft, limit plates sleeved on both sides of the threaded shaft, and limit rods symmetrically arranged on both sides of the limit plates, the limit rods all pass through the lifting block, and sealing plates are provided at both ends of the lifting block, and soft rubber is provided at the free end of the sealing plate.

[0030] Furthermore, the maximum upward movement distance of the lifting block is the middle section of the receiving barrel, and the maximum downward movement distance of the lifting block is the junction of the receiving barrel and the mixing barrel. The lifting assembly is designed to use the self-rotation action and the matching controller to make the lifting assembly do up and down reciprocating motion, bringing the gelling slurry upward to mix with the fluid slurry. This feature is slow mixing and gradual fusion. This design can reduce the phenomenon of the gelling slurry becoming granular and mixed in the fluid slurry.

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0038] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:

[0039] A construction equipment for water conservancy and hydropower engineering, comprising a mixing barrel 1, a driving rotating shaft 9 arranged inside the mixing barrel 1, a mixing and stirring disk 8 arranged in sequence from bottom to top on the driving rotating shaft 9, a stirring receiving member connected to the driving rotating shaft 9 bearing, a filter disk coaxially connected to the driving rotating shaft 9, a feeding assembly connected to the driving rotating shaft 9 bearing and an end cover 5 detachably connected to the mixing barrel 1, wherein the driving rotating shaft 9 is provided with a driving member;

[0040] like Figure 1As shown, in the overall structure, the bottom of the end cap 5 is provided with an external thread 6, the inner side of the top of the mixing barrel 1 is provided with an internal thread groove, the end cap 5 and the mixing barrel 1 are connected by threaded connection, the outer side of the bottom of the mixing barrel 1 is fixedly connected with a load-bearing plate 2, and a plurality of support columns 3 are evenly fixedly connected around the load-bearing plate 2, and the free ends of the support columns 3 are fixedly connected with rubber anti-skid pads. The stable installation of the device and the quick installation and quick disassembly between the end cap 5 and the mixing barrel 1 are realized.

[0041] About the feeding components:

[0042] The feed assembly includes a receiving groove 7 opened on the end cover 5, a guide cylinder 13, a plurality of guide pipes 12 and a feed plate 11, one end of each guide pipe 12 is connected to the feed plate 11, the feed plate 11 passes through the receiving groove 7 and is located on the upper side of the end cover 5, the other end of the guide pipe 12 is connected to the guide cylinder 13, the bottom of the guide cylinder 13 is provided with an outlet, the outlet is located above the filter plate, and the guide cylinder 13 is connected to the driving rotating shaft 9 through a bearing. After feeding, the material flows through the guide pipe 12 and then flows to the top of the filter plate.

[0043] Specifically: The first innovation of this case is that: for the gelling slurry, since the raw materials in the gelling slurry will only produce viscosity after mixing with water, for this reason, the device does not directly use the gelling slurry, but uses the raw materials in the gelling slurry to be put in, and then mixed with water to form the gelling slurry;

[0044] Therefore, the raw materials in the gelled slurry enter from the guide tube 12 first, then fall out from the outlet at the bottom of the guide cylinder 13, and then fall on the top of the filter disc;

[0045] About the filter disc: the filter disc includes a disc body 16, a filter screen 14 arranged on the filter disc and a guide sliding column 15 arranged outside the disc body 16. A guide groove is opened on the inner wall of the mixing barrel 1 corresponding to the guide sliding column 15. The guide sliding column 15 is slidably connected with the guide groove, and the disc body 16 is coaxially connected with the driving rotating shaft 9. This case adopts a gelling slurry raw material processing mode, that is, the raw materials in the gelling slurry are no longer mixed with water first, and the particles are filtered first and then mixed with water later, so as to remove impurities from the particle raw materials first.

[0046] Since the disc body 16 is coaxially connected with the driving rotating shaft 9, the entire filter disc will rotate, the main purpose is to accelerate, the raw materials in the gelling slurry continue to fall, and the purpose of the filter screen 14 is to remove raw material impurities in the non-gelling slurry, such as stones, etc., to improve the quality of the subsequent gelling slurry;

[0047] Then, the guide pipe 12 is used to add water, and the water passes through the filter disc and mixes with the raw materials in the gelling slurry to form a gelling slurry, and they are mixed in the stirring receiving member;

[0048] The stirring receiving member comprises a stirring barrel 20 and a receiving barrel 18, wherein a cavity 28 is arranged inside the stirring barrel 20, and a fixing column 17 is symmetrically fixedly connected to the outer side of the receiving barrel 18, and the fixing column 17 is fixed to the inner wall of the mixing barrel 1, and a plurality of electrically controlled switch valves 19 are arranged on the outer periphery of the receiving barrel 18, and stirring rods 29 are arranged around the driving rotating shaft 9 located in the stirring barrel 20, and the stirring rods 29 are installed in the cavity 28, and the driving rotating shaft 9 located in the stirring barrel 20 and the receiving barrel 18 is a threaded shaft 21, and the threaded shaft 21 is threadedly connected to a lifting assembly that can close the intersection of the stirring barrel 20 and the receiving barrel 18, and a forward and reverse controller electrically connected to the driving member is arranged on the lifting assembly, and an extrusion sieve plate is arranged on the driving rotating shaft 9 located at the bottom of the mixing barrel 1, and a discharge port 31 is arranged on the outer bottom of the mixing barrel 1, and a liquid inlet for feeding slurry into the stirring receiving member is arranged on one side of the mixing barrel 1.

[0049] The driving member is a motor 10, the upper end of the driving rotating shaft 9 passes through the guide barrel 13 and is coaxially connected to the motor 10, the forward and reverse controller is electrically connected to the motor 10, the stirring barrel 20 and the receiving barrel 18 are integrally formed, the connection between the stirring barrel 20 and the receiving barrel 18 is rounded, and the liquid inlet is installed with a liquid inlet pipe 4, the liquid inlet pipe 4 is used to put in the slurry with fluidity, and the height of the liquid inlet is higher than the height of the receiving barrel 18. The slurry with fluidity enters the receiving barrel 18 from the top.

[0050] The lifting assembly includes a lifting block 24 threadedly connected to the threaded shaft 21, a limit plate sleeved on both sides of the threaded shaft 21, and a limit rod 23 symmetrically arranged on both sides of the limit plate. Figure 2 As shown, it is divided into a first limit plate 22 and a second limit plate, the limit rods 23 are all passed through the lifting block 24, the two ends of the lifting block 24 are provided with blocking plates 25, and the free ends of the blocking plates 25 are provided with soft rubber 26;

[0051] Connecting with the mixing in the stirring receiving part mentioned above, specifically: the formation of gelled slurry is realized in the stirring barrel 20 based on the action of the stirring rod 29, and the gelled slurry begins to be gradually formed. The liquid inlet is installed with a liquid inlet pipe 4, and the liquid inlet pipe 4 is used to put in the slurry with fluidity. At this time, the fluid slurry enters from the receiving barrel 18;

[0052] The specific process is as follows:

[0053] Since the motor 10 rotates continuously, and the lifting block 24 can contact the limit plate after moving up and down, a pressure sensor is also included, and the pressure sensor is electrically connected to the forward and reverse controller. The pressure sensor is divided into a first pressure sensor and a second pressure sensor, and the rotation direction of the driving member is changed by the pressure change of the first pressure sensor and the second pressure sensor, so as to realize the up and down movement of the lifting assembly.

[0054] The maximum upward movement distance of the lifting block 24 is the middle section of the receiving barrel 18, and the maximum downward movement distance of the lifting block 24 is the junction of the receiving barrel 18 and the mixing barrel 20. The lifting assembly is designed to make the lifting assembly reciprocate up and down by using the self-rotation action and the matching controller to bring the gelling slurry upward and mix it with the fluid slurry. This feature is slow mixing and gradual fusion. This design can reduce the phenomenon that the gelling slurry becomes granular and mixed in the fluid slurry.

[0055] About slow mixing and gradual blending:

[0056] First, all the gelled slurry is stirred in a circular motion in the mixing barrel 20. Then, as is known, the lifting block 24 moves up and down, and the junction between the receiving barrel 18 and the mixing barrel 20 is a closed and unclosed reciprocating process.

[0057] Then, for the fluid slurry, when it is not sealed, it flows into the stirring barrel 20 and mixes with the gelling slurry, and then the stirring rod 29 enters the gelling slurry and mixes with the gelling slurry, and then it is sealed, and then when it is not sealed again, the above steps are repeated. Overall, it is slowly mixed and gradually merged. The advantage of this is that although the process is slow, the mixing is more sufficient, giving the gelling slurry and the gelling slurry time to mix and merge, reducing the phenomenon that the gelling slurry becomes granular and mixed in the fluid slurry;

[0058] As the fluid slurry is poured in, it fills up the receiving barrel 18. At this time, the electric control switch valve 19 is opened, and after the mixed liquid flows out, it is finally mixed and stirred by the mixing and stirring disk 8 to achieve thorough mixing of the gelling slurry and the fluid slurry.

[0059] Here, the question of proportion is needed, that is, the amount of fluid slurry, water, and gelling slurry;

[0060] Because, in this case, water is used to clean the raw materials of the above-mentioned residual gelling slurry to ensure the accuracy of the raw materials of the gelling slurry. Secondly, after the electric control switch valve 19 is opened, the mixed slurry flows out from the receiving barrel 18. For the receiving barrel 18 and the mixing barrel 20, there is residual mixed slurry. Therefore, secondary water is needed here, and water can be added using the liquid inlet pipe 4 to clean the residual fluid slurry and gelling slurry in the receiving barrel 18 and the mixing barrel 20.

[0061] For water, Figure 1 As shown, since part of the water will remain in the mixing barrel 20 and cannot flow out, it is necessary to consider the redundancy of water when using water, and ensure that the ratio is within a reasonable error by using the amount of water reasonably, so that the ratio of the mixed slurry is correct, and the subsequent use quality is improved;

[0062] Connecting with the above:

[0063] After the mixed liquid flows out, it is finally mixed and stirred by the mixing and stirring disk 8 to achieve thorough mixing of the gelling slurry and the fluid slurry. In practice, there may still be granular substances. Such granular substances may be the gelling slurry naturally agglomerates, resulting in the fluid slurry being unable to mix with the gelling slurry. The above-mentioned slow mixing design has tried to avoid this phenomenon. However, in practice, there are many uncontrollable factors, such as temperature and humidity environment, and the gelling slurry naturally agglomerates. Therefore:

[0064] At this time, the squeeze sieve plate is set;

[0065] Extrusion screening plate: It includes a support frame 32 and a screening net 30 arranged between the support frames 32. The driving rotating shaft 9 is coaxially connected to the support frame 32. The extrusion screening plate is located above the discharge port 31. The discharge port 31 is provided with a mechanical switch for discharging. To achieve the final screening, the support frame 32 contacts the upper surface of the screening net 30. The main purpose is to screen out the unmixed large particles and ensure the uniformity of the mixed material.

[0066] Finally, the mixed slurry flows out from the discharge port 31 by opening the mechanical switch, and can be collected and used by relevant personnel.

[0067] The device solves the problem that the fluid and gelling slurries cannot be fully mixed in the rock foundation grouting process in traditional water conservancy and hydropower projects.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
