Description

Technical Field

[0001] This utility model relates to the field of mud pumping technology, and in particular to a pumping device for water conservancy projects. Background Technology

[0002] In the field of water conservancy engineering, pumping units, as core equipment, are widely used in engineering scenarios such as river dredging, farmland irrigation, flood control and drainage, and dam reinforcement. With the continuous expansion of water conservancy projects and the increasing complexity of construction environments, higher demands are placed on the multifunctionality, adaptability, and reliability of pumping units. Especially when dealing with mixed fluids containing large amounts of silt and impurities, traditional pumping equipment struggles to simultaneously meet the dual requirements of efficient water pumping and sludge treatment.

[0003] The existing technology has the following shortcomings;

[0004] 1) Traditional pumping devices often employ a single filtration structure or simple centrifugal separation, which has limited effectiveness in intercepting impurities such as silt and sand. When processing fluids with high sand content, problems such as filter clogging and incomplete separation easily occur, leading to decreased equipment operating efficiency and even shutdown due to overload, failing to meet the continuous operation requirements of water conservancy projects. Furthermore, the lack of effective flow guidance and pushing structures during the transport of the separated slurry further reduces the overall processing efficiency.

[0005] 2) Poor adaptability to operating conditions: The inlet channels and flow regulation methods of existing equipment are relatively fixed, making it difficult to flexibly adjust according to actual operating conditions such as water level changes and fluid concentration. When water level fluctuates significantly or fluid flow demand changes, frequent manual adjustment of equipment parameters or even replacement of parts is required, which is cumbersome and slow in response. At the same time, the sealing performance of some devices is insufficient, and leakage is prone to occur under high water pressure, affecting the stability and safety of the equipment. Utility Model Content

[0006] The purpose of this invention is to solve the problems of low solid-liquid separation efficiency, poor adaptability to working conditions, and insufficient automation in the existing technology, and to propose a pumping device for water conservancy projects.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a pumping device for water conservancy projects, comprising a through sleeve, wherein a mud conveying device is provided inside the through sleeve; the mud conveying device comprises a mounting base, a rotating shaft is rotatably connected to the outer surface of the mounting base, an auger blade is fixedly connected to the outer wall of the rotating shaft, a soil baffle is provided on the outer wall of the auger blade, a first gear is fixedly connected to the other end of the rotating shaft, a first gate is rotatably connected to the top of the rotating shaft, and a mud outlet is fixedly connected to the outer wall of the first gate.

[0008] Preferably, multiple sets of flow grooves are formed through the outer wall of the sleeve, and a sealing device is fixedly connected to the outer wall of each flow groove;

[0009] Preferably, the sealing device includes a set of mounting seats, each set of mounting seats having a connecting pipe fixedly connected to its top, and a second gate slidably connected to the outer wall of the connecting pipe.

[0010] Preferably, a transmission ring is fixedly connected to the outer wall of the second gate, and the output end of an electric telescopic rod is fixedly connected to the outer surface of the transmission ring.

[0011] Preferably, a flange mounting pipe is fixedly connected to one end of the sleeve, and a set of first guide plates is installed inside the flange mounting pipe.

[0012] Preferably, the outer wall of the sleeve has an installation groove, a motor is fixedly installed inside the installation groove, and a second gear is fixedly connected to the output end of the motor.

[0013] Preferably, the top of the mounting base is fixedly mounted on the outer wall of the sleeve, and the outer walls of the auger blade and the outer walls of the soil baffle cooperate with each other.

[0014] Preferably, the outer wall of the soil baffle is fixedly connected to the inside of the sleeve.

[0015] Preferably, the first guide plate and the soil baffle cooperate with each other.

[0016] Preferably, the outer wall of the second gear and the outer wall of the first gear mesh with each other.

[0017] Preferably, a second guide plate is fixedly connected inside the sleeve, and the second guide plate is fixed between each group of flow channels.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. This utility model achieves highly efficient integration of pumping and mud treatment through the coordinated design of the mud conveying device, sealing device, and flow guiding structure. The cooperation between the auger blades and the soil baffle allows for preliminary separation of mud and sand during mud conveying, improving interception efficiency and effectively reducing the risk of clogging in subsequent treatment equipment. The dual flow guiding system formed by the first and second flow guiding plates accelerates the solid-liquid separation speed and optimizes fluid distribution, reducing the energy consumption of the device. Simultaneously, multiple sets of flow channels and the electrically controlled sealing device can flexibly adjust the inlet water volume according to water level and flow requirements, improving adaptability to complex working conditions compared to traditional equipment.

[0020] 2. In this utility model, the modular and automated design significantly improves the ease of use and reliability of the equipment. The electric telescopic rod of the sealing device can realize the automatic opening and closing of the second gate, avoiding human operation errors; its modular structure supports the rapid addition and removal of sealing units. When it is necessary to increase the pumping flow rate, it can be achieved by increasing the number of open flow channels without modifying the main body of the equipment, thus reducing maintenance costs.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: Please refer to the attached document. Figure 1 -Appendix Figure 5As shown, this utility model provides as follows Figure 1 As shown, the pumping device for water conservancy projects in this embodiment includes a sleeve 1, and a mud conveying device 2 is installed inside the sleeve 1. The mud conveying device 2 includes a mounting base 201, a rotating shaft 202 is rotatably connected to the outer surface of the mounting base 201, an auger blade 203 is fixedly connected to the outer wall of the rotating shaft 202, a soil baffle 204 is provided on the outer wall of the auger blade 203, a first gear 205 is fixedly connected to the other end of the rotating shaft 202, a first gate 206 is rotatably connected to the top of the rotating shaft 202, and a mud outlet 207 is fixedly connected to the outer wall of the first gate 206.

[0030] The overall effect of Embodiment 1 is as follows: The mud conveying function is achieved: the mounting base 201 serves as the supporting foundation for the rotating shaft 202, enabling the rotating shaft 202 to rotate stably. The rotating shaft 202 drives the auger blades 203 to rotate. The spiral structure of the auger blades 203 effectively conveys the mud passing through the sleeve 1, realizing the movement of the mud from one end of the device to the mud outlet 207. This meets the basic requirements for mud extraction and conveying in water conservancy projects and can be applied to mud conveying work in scenarios such as river dredging. Impurity blocking and preliminary separation: the soil baffle 204 is set on the outer wall of the auger blades 203. During the mud conveying process, it can block larger particles of impurities in the mud, intercepting large particles and achieving preliminary separation of mud and impurities. This reduces the impact of impurities on the equipment in subsequent processing stages and lowers the cost of subsequent filtration. To reduce the probability of blockage and improve the operational stability and service life of the equipment, the first gate 206, which is rotatably connected to the top of the rotating shaft 202, can control the opening and closing degree of the mud outlet 207 by rotation, thereby flexibly adjusting the mud conveying flow rate. According to different water conservancy project conditions, such as mud concentration and conveying distance, the output of mud can be precisely controlled, enabling the pumping device to adapt to diverse working requirements and improve the applicability and working efficiency of the equipment. Stable power transmission: The first gear 205, which is fixedly connected to the other end of the rotating shaft 202, provides a stable power input method for the rotating shaft 202. Through cooperation with other gears, the power can be stably transmitted to the rotating shaft 202, ensuring the stable rotation of the auger blades 203, thereby ensuring the continuity and stability of the mud conveying process, and enabling the pumping device to work continuously and efficiently.

[0031] Example 2: Please refer to the attached document. Figure 1 -Appendix Figure 5As shown, the pumping device for water conservancy projects in this embodiment has multiple sets of flow channels 11 opened on the outer wall of the sleeve 1. Each flow channel 11 has a sealing device 3 fixedly connected to its outer wall. The sealing device 3 includes a set of mounting seats 301. The top of each set of mounting seats 301 is fixedly connected to a connecting pipe 302. The outer wall of the connecting pipe 302 is slidably connected to a second gate 303. The outer wall of the second gate 303 is fixedly connected to a transmission ring 304. The outer surface of the transmission ring 304 is fixedly connected to the output end of an electric telescopic rod 305.

[0032] The overall effect of Embodiment 2 is as follows: Multi-channel water inlet and flow control: Multiple sets of flow channels 11 opened on the outer wall of the sleeve 1 and the sealing device 3 connected to them realize the setting of multiple water inlet channels. Each flow channel 11 can be independently opened and closed by the sealing device 3 according to actual working needs, thereby flexibly adjusting the flow rate of water entering through the sleeve 1. According to different water level and flow requirements in water conservancy projects, the amount of water entering can be precisely controlled, improving the adaptability of the pumping device to different working conditions. Automated control and convenience: The use of the electric telescopic rod 305 realizes the automated control of the second gate 303. It can automatically control the second gate 303 according to the preset program or real-time working status. The opening and closing of the sealing device 3 eliminates the need for frequent manual operation, improving the automation level and work efficiency of the equipment. Furthermore, this automated control method can quickly respond to different work requirements, ensuring that the pumping device maintains good operating condition under various working conditions. Modular design and expandability: The sealing device 3 adopts a modular design, with each set of components such as mounting base 301, connecting pipe 302, and second gate 303 forming an independent sealing unit. By setting multiple sets of such sealing devices 3 on the outer wall of the sleeve 1, they can be selectively activated according to actual flow requirements, providing good expandability. When it is necessary to increase the pumping flow, more sealing devices 3 can be opened without large-scale equipment modifications, reducing the cost and difficulty of equipment modification.

[0033] Example 3: Please refer to the attached document. Figure 1 -Appendix Figure 5 As shown, a flange mounting pipe 12 is fixedly connected to one end of the sleeve 1. A set of first guide plates 13 are installed inside the flange mounting pipe 12. An installation groove 4 is opened on the outer wall of the sleeve 1. A motor 41 is fixedly installed inside the installation groove 4. A second gear 42 is fixedly connected to the output end of the motor 41. The top of the mounting base 201 is fixedly installed on the outer wall of the sleeve 1. The outer wall of the auger blade 203 and the outer wall of the soil baffle 204 cooperate with each other. The outer wall of the soil baffle 204 is fixedly connected to the inside of the sleeve 1. The first guide plate 13 and the soil baffle 204 cooperate with each other. The outer wall of the second gear 42 and the outer wall of the first gear 205 mesh with each other. A second guide plate 5 is fixedly connected to the inside of the sleeve 1. The second guide plate 5 is fixed between each set of flow channels 11.

[0034] The overall effect of Embodiment 3 is to accelerate the solid-liquid separation process: the first guide plate, through its special curved surface and angle design, can change the trajectory of the mud-water mixture, causing it to flow towards the soil baffle 204 more quickly. Under the action of centrifugal force and guidance, the separation speed of mud and water is increased by about 30%, and more mixed fluid can be processed per unit time, improving the overall working efficiency of the pumping device. It is especially suitable for water conservancy projects with high sand content. It also enhances the interception effect: the mud and water are quickly guided to the soil baffle 204, allowing the soil baffle 204 to play a more significant role. The interception function allows larger particles of silt to be more easily intercepted by the soil baffle 204 under high-speed impact, reducing the conveying burden on the subsequent auger blades 203, reducing equipment wear caused by excessive impurities, extending the service life of the device, and optimizing fluid distribution: the first guide plate guides the silt and water, making the distribution of the mixed fluid more uniform as it passes through the sleeve 1, avoiding situations where the local flow velocity is too fast or too slow. This uniform fluid distribution helps the auger blades 203 to operate stably, reducing vibration and energy consumption caused by uneven force, and making the device operate more smoothly and reliably.

[0035] Working Principle: When a water conservancy project requires pumping or mud transport operations, the entire device enters the operating state. External power is output through motor 41. The rotation of motor 41 drives the second gear 42. Through the meshing transmission between the second gear 42 and the first gear 205, the power is transmitted to the rotating shaft 202, causing the rotating shaft 202 to drive the auger blades 203 to start rotating. During the mud transport process, mud containing impurities such as silt and sand enters from one end of the sleeve 1. The first guide plate 13 guides the incoming silt-water mixture. Utilizing a special curved surface and angle design, the fluid trajectory is changed, causing it to quickly flow towards the soil baffle 204. Under the action of centrifugal force, the silt and water are accelerated to separate. The soil baffle 204 intercepts larger particles of silt, achieving preliminary solid-liquid separation and reducing the impurity content entering the auger blades 203. The auger blades 203, with their spiral structure, transport the preliminarily separated mud axially. The mud is finally connected to the rotating shaft 202 at the top. The first gate 206 controls the flow rate, discharging the water from the mud outlet 207. Simultaneously, multiple sets of flow channels 11 on the outer wall of the sleeve 1 control the inflow and outflow of water. According to actual working conditions, the electric telescopic rod 305 drives the transmission ring 304, causing the second gate 303 to slide on the connecting pipe 302, thereby opening or closing the corresponding flow channel 11. When the second gate 303 is open, the water can enter the sleeve 1 through the connecting pipe 302 or exit from the sleeve 1. The second guide plate 5 is fixed between each set of flow channels 11. Its function is to guide and rectify the water flow after it has been filtered by the soil baffle 204, optimize the fluid distribution, and enable the water flow to be discharged more smoothly through the flow channel 11. At the same time, it reduces the impact of the water flow on the inside of the device, ensuring the stable operation of the entire pumping device. When an external water pump is connected, the suction generated by the water pump will assist the flow of water and mud, further improving the pumping and mud transport efficiency to meet the operational requirements of different water conservancy projects.

Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the first gate 206, the second gate 303, the electric telescopic rod 305, and the motor 41 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
