Description

Technical Field

[0001] This application relates to the field of mud pumping technology, specifically to an auxiliary pumping device for a lake submersible mud pump. Background Technology

[0002] Traditional dredging operations in lakes or reservoirs primarily employ mechanical excavation (excavator digging). This method utilizes the buckets of shore-based or boat-mounted excavators to directly excavate and transfer the silt from the bottom. However, this mechanical excavation method faces stability challenges: when floating on the water surface, the excavation reaction force causes swaying and capsizing risks; the operating water depth is shallow, typically limited to areas slightly deeper than the track depth; and it is inefficient, has high resistance, and can cause significant wear and tear on the float and tracks. In dredging environments with deep silt, no water flow, or poor flow, the excavator's excessive weight can prevent it from entering the working area or easily cause it to sink and become trapped, potentially leading to other property damage. Furthermore, the limited reach of the robotic arm restricts the effective operating range, allowing only the clearing of narrow areas near the shore and preventing operations in areas far from the bank. Utility Model Content

[0003] To address this issue, this application provides a submersible mud pump auxiliary pumping device for lakes, which solves the problem that existing lake dredging operations have limited operating range and that excavators can only work in specific scenarios due to their own weight.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0006] Optionally, the buoyancy module is a float structure, which includes four floats;

[0007] The fixed support includes a base frame, and two uprights are symmetrically arranged at the middle positions on the left and right sides of the base frame. The tops of the two uprights are connected by a crossbar, and the electric hoist is located at the middle position of the bottom of the crossbar.

[0008] The four pontoons are respectively located at the front left end, front right end, rear left end, and rear right end of the base frame.

[0009] Optionally, the bottom of the base frame forms four semi-circular positioning grooves, the curvature of which matches the outer diameter of the pontoons, and are used to place the four pontoons one by one.

[0010] Optionally, the base frame is provided with a through hole in the middle for mud pump operation;

[0011] The bottom of the crossbar is provided with a track for the electric hoist to move.

[0012] Optionally, it also includes a control module and a power supply device, wherein the control module is connected to the mud pump and the electric hoist and is used to control the operation of the mud pump and the electric hoist;

[0013] The power supply equipment includes a power module, which is connected to two independent cables and supplies power to the electric hoist and the mud pump.

[0014] Optionally, the two cables are laid along the drainage pipe, and the two main cables are bundled and fixed together with the drainage pipe; when the two main cables are laid to a position close to the base frame, one cable passes through the base frame, the upright, and the crossbar in sequence, and is bundled and fixed by multiple spaced cable ties, and finally connects to the wiring port of the electric hoist; the other cable extends along the drainage pipe and connects to the wiring port of the mud pump.

[0015] Optionally, the drain pipe is a flexible hose, and the drain pipe is connected to the sewage outlet via a clamp structure;

[0016] The fixed bracket is also equipped with lifting lugs for connecting the crane.

[0017] Optionally, a pulley assembly, hook, and towing rope are also provided. The pulley assembly includes a housing, one end of which is equipped with a pulley, and the other end is provided with a fixing lug with mounting holes. The fixing lug is fixed to the shore.

[0018] The hook body is connected to the corresponding position of the base frame. One end of the hook body is integrally provided with a hanging ring. One end of the traction rope is connected to the hanging ring, and the other end passes around the rope groove of the pulley and leads to the operating area.

[0019] Alternatively, the electric hoist can be replaced by a winch.

[0020] Optionally, the buoyancy module is an inflatable float, and the float is connected to an inflation device.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. Based on further analysis and research of existing technical problems, this application provides an auxiliary pumping device for lake submersible mud pumps, including a fixed support and a buoyancy module installed at its bottom. The buoyancy module provides buoyancy for the entire pumping device, enabling it to float stably on the water surface. An electric hoist is installed on the top of the fixed support, and the hook at the end of its wire rope is used to connect to the lifting ring on the top of the mud pump. The suction inlet of the mud pump is submerged underwater during operation, and the discharge outlet of the mud pump is connected to a drain pipe for transporting mud to the onshore drainage system. By integrating the buoyancy module (float), electric hoist, and mud pump onto a movable fixed support, an integrated working platform is formed. This design makes the overall structure simple and compact, highly reliable, and extremely convenient to deploy and operate, making it particularly suitable for dredging operations in shallow, still water environments such as lakes and reservoirs. At the same time, the mud pump can be easily lifted above the water surface by the electric hoist, facilitating quick inspection and clearing of blockages, greatly shortening maintenance time and reducing maintenance difficulty.

[0023] 2. The four pontoons of this application are symmetrically arranged at the four corners of the base frame to provide balanced support. At the same time, a semi-circular positioning groove that cooperates with the pontoons is provided at the bottom of the base frame. This structure not only makes the installation and placement of the pontoons quick and easy, but more importantly, it realizes the radial positioning and circumferential limiting of the pontoons, effectively preventing them from sliding or rolling laterally during use. This connects the pontoons and the fixed bracket as one unit, enhancing the stability of the entire working platform.

[0024] 3. This application also includes a control module, which allows for real-time fine-tuning of the mud pump's depth during operation to maintain optimal suction efficiency.

[0025] 4. The power supply cable of this application is laid along the fixed bracket and drainage pipe according to specifications and is fixed with cable ties, which facilitates inspection and troubleshooting, and is neat and beautiful.

[0026] 5. This application is also equipped with a pulley assembly, hook and towing rope, so that the operator can remotely control the movement and positioning of the entire pumping device on the water surface by raising and lowering the towing rope without wading in the water. This simplifies the operation, saves manpower, reduces labor intensity, and ensures high safety. Attached Figure Description

[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0041] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0042] like Figures 1-9 As shown in one embodiment of this application, a lake submersible mud pump auxiliary pumping device includes: a fixed bracket 1, a mud pump 3, and a buoyancy module;

[0043] A buoyancy module is installed at the bottom of the fixed support 1. The buoyancy module is used to provide buoyancy and make the entire pumping device float stably on the water surface. An electric hoist 2 is installed at the top of the fixed support 1. The electric hoist 2 includes a wire rope 201. The hook 202 at the end of the wire rope 201 is used to connect to the lifting ring 301 at the top of the mud pump 3. The suction port 302 of the mud pump 3 is located at the bottom of its pump body and is submerged in water during operation. The discharge port of the mud pump 3 is located on the side of its pump body and is connected to the drain pipe 5. The drain pipe 5 is used to transport the mud to the onshore drainage system.

[0044] Preferably, the buoyancy module is a float structure, which includes multiple floats 4, each float 4 being a sealed cavity structure;

[0045] The fixed support 1 includes a base frame 101, and two uprights 102 are symmetrically arranged at the middle positions on the left and right sides of the base frame 101. The tops of the two uprights 102 are connected by a crossbar 103, and the electric hoist 2 is located at the middle position of the bottom of the crossbar 103.

[0046] Multiple pontoons 4 are respectively set at corresponding positions on the base frame 101; in this embodiment, a total of four pontoons 4 are set, and the four pontoons 4 are respectively set at the front left end, front right end, rear left end and rear right end of the base frame 101.

[0047] During the overall structural design phase, the number, size, and arrangement of the pontoons 4 must be determined based on the system's load calculations. It must be ensured that the total net buoyancy provided by all pontoons 4 is greater than the total weight of the device under maximum operating conditions, guaranteeing that the entire device can float stably at the operating water depth, with a specified safety margin. The aforementioned electric hoist 2 can also be replaced by a winch.

[0048] In another embodiment, the buoyancy module may also employ inflatable floats, by setting up multiple inflatable floats and connecting them to an inflation device.

[0049] More preferably, the bottom of the base frame 101 forms four semi-circular positioning grooves 104. The positioning grooves 104 are composed of multiple semi-circular iron pieces distributed at intervals. Their curvature is adapted to the outer diameter of the floats 4 and is used to place the four floats 4 one by one.

[0050] Preferably, the fixed bracket 1 may also be provided with lifting lugs for connecting a crane or other lifting equipment.

[0051] Preferably, such as Figures 2-4 As shown, a through hole 105 for the operation of the mud pump 3 is provided in the middle of the base frame 101. The pump body of the mud pump 3 passes through this through hole to achieve up and down lifting and small-amplitude swinging.

[0052] Preferably, the bottom of the crossbar 103 is provided with a section of track for the electric hoist 2 to move. This track design allows the electric hoist 2 to move slightly and controllably along the crossbar 103. Thus, without changing the overall structural positioning, the mud pump 3 can perform multi-point pumping and discharging operations by adjusting the hoist's lifting point position, thereby improving work efficiency.

[0053] Preferably, it also includes a control module, which is connected to the mud pump 3 and the electric hoist 2, and is used to control the operation of the mud pump 3 and the electric hoist 2.

[0054] Preferably, it also includes power supply equipment, which includes a power module. The power module is connected to two independent cables 7, which supply power to the electric hoist 2 and the mud pump 3 respectively. See [reference needed]. Figure 2 , Figure 4 .

[0055] More preferably, the two cables 7 are laid along the drainage pipe 5, and the two main cables are bundled and fixed together with the drainage pipe 5 by corresponding cable ties 8; when the two main cables are laid to a position close to the base frame 101, one cable 7 passes through the base frame 101, the left upright 102, and the crossbar 103 in sequence, and finally connects to the wiring port of the electric hoist 2. This cable 7 is bundled and fixed to the corresponding positions of the upright 102 and the crossbar 103 by multiple spaced cable ties 8; the other cable 7 extends with the drainage pipe 5 and finally connects to the wiring port of the mud pump 3.

[0056] Preferably, the drain pipe 5 is a flexible hose, and the drain pipe 5 is connected to the sewage outlet via a clamp structure 6, see [reference]. Figure 3 , Figure 5The connection between the drain pipe 5 and the sewage outlet is reinforced by a clamp structure 6. This clamp structure 6 is an adjustable open clamp structure 6, which specifically includes a clamp body 61. One end of the clamp body 61 is a flat lug with a strip-shaped mounting hole, and the other end of the clamp body 61 is provided with a threaded section. During installation, the threaded section is passed through the mounting hole of the flat lug, and the clamp body 61 is locked in place by the matching nut 62 on its outside. Of course, in practical applications, this clamp structure 6 can also adopt other equivalent fastening methods as needed.

[0057] Preferably, the assembly also includes a pulley assembly 11, a hook 9, and a traction rope 10. The pulley assembly 11 includes a housing 111, a pulley 112 is installed at one end of the housing 111, and a fixing lug 113 with mounting holes is provided at the other end. The fixing lug 113 is fixed to the shore.

[0058] The hook 91 of the hook 9 is connected to the corresponding position of the base frame 101, for example, it can be set on the diagonal brace 106 between the base frame 101 and the upright 102. One end of the hook 91 is integrally provided with a hanging ring 92. One end of the traction rope 10 is connected to the hanging ring 92, and the other end passes around the rope groove of the pulley 112 and is led to the operating area. When it is necessary to change the working position, the operator can stand safely on the shore and control the entire pumping device to move towards the shore or offshore by pulling or releasing the traction rope 10, so as to move the entire pumping device to the next pumping point. The operation is simple and safe.

[0059] The installation of the pulley assembly 11 described above can be achieved in the following two ways:

[0060] Option 1: As Figures 1-7 As shown, the mounting holes of the fixed ear plate 113 are directly fitted and fastened to the pre-embedded anchor bolts 13, or tied to the anchor bolts 13 by cable ties or ropes, so as to achieve a rigid connection between the pulley assembly 11 and the ground; the traction rope 10 passes around the rope groove of the pulley 112 and is led to the operating area.

[0061] The second option: Figure 8 , Figure 9 As shown, a stable and independent frame 12 is first fixed on the shore, and then the fixing lug 113 of the pulley assembly 11 is installed on the top crossbeam of the frame 12. The traction rope 10 also passes around the rope groove of the pulley 112 and is led to the operating area.

[0062] The operating principle of the above embodiments:

[0063] First, on the shore, the lifting ring 301 on the top of the mud pump 3 is attached to the hook 202 at the end of the wire rope 201 of the electric hoist 2, completing the mechanical connection between the two. Then, using a crane or other lifting equipment, the assembled pumping device (including the fixed support 1, mud pump 3, and buoyancy module) is lifted smoothly through the pre-set lifting lugs on the fixed support 1, transported and lowered to the pre-set pumping point in the water. After the entire device enters the water, it floats stably on the water surface by relying on the buoyancy of the buoyancy module (i.e., the float 4 structure).

[0064] Then, the operator controls the electric hoist 2 through the control module to slowly lower the wire rope 201, so that the suction port 302 at the bottom of the mud pump 3 is submerged underwater and close to the surface of the silt layer; after the pump body is stable, the mud pump 3 is started to begin the pumping operation; during the operation, the depth of the mud pump 3 can be finely adjusted in real time through the control module to maintain the best pumping efficiency.

[0065] When it is necessary to change the working position, hooks 9 can be set in advance at the corresponding positions of the base frame 101 and connected to the pulley assembly 11 fixed on the shore by the traction rope 10; during the transfer, the operator can control the entire pumping device to move horizontally to the next pumping point by raising and lowering the traction rope 10 on the shore.

[0066] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
