Description

Technical Field

[0001] This utility model relates to the field of mud pump technology, and more specifically, to a self-floating mud pump. Background Technology

[0002] In the construction of water pumping in steel cofferdams, there are generally two main pumping methods. The first method is to use a chain hoist to suspend and fix the mud pump at a certain height for pumping. During the pumping process, a dedicated person needs to monitor the water level and adjust the pump height in a timely manner. If the water level drops or rises instead of being pumped smoothly, and the pump height is not adjusted in time, the pump will not be able to pump water normally or the pump motor will be submerged, causing the pump motor to burn out and affecting the construction. This pumping method requires frequent manual adjustment of the pump height, which is time-consuming and labor-intensive. The second method is to use a crane to lift the water pump for pumping. This method requires the crane to be frequently lifted and moved to different positions, and occupies the crane for a long time, which is more cumbersome. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the problems existing in the prior art, this utility model provides a self-floating mud pump to solve the technical problems mentioned in the background art, such as the inconvenience of using the prior art mud pump and its inability to automatically adjust to the floating mud level.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-floating mud pump includes a float, on which a pump body is mounted. An inlet pipe is located at the bottom of the pump body, and a water inlet is provided on the float. The inlet pipe extends through the inlet to a suitable position below the float. An outlet pipe is connected to the pump body, and a connector is located at the bottom of the inlet pipe. A protective mesh is installed on the connector in conjunction with the inlet pipe. The mesh openings of the protective mesh allow mud to pass through but prevent large particles such as stones from passing through, thereby reducing damage to the pump body. Guardrails are provided on both sides of the float, and cables are connected to the guardrails, forming an anchoring mechanism. The guardrails are diagonally fixed to a cofferdam using cables. The cable length is calculated based on the required pumping depth and is reserved to prevent the cables from breaking when tightened.

[0008] The present invention is further configured such that the float includes a float cylinder, two float cylinders are symmetrically arranged, a float plate is connected between the two float cylinders, the water pump inlet is opened on the float plate, and the guardrail is set on the two float cylinders. The float cylinder is made of 630 steel pipe pile of appropriate length, and 10mm steel plates are welded on both sides of the pipe pile to form a closed state.

[0009] The present invention is further provided that the float plate is provided with a first fixing frame, the first fixing frame being a grid-shaped frame, which is used to fix the water pump body and improve the installation stability of the water pump body on the float.

[0010] The present invention is further configured such that both ends of the pontoon are provided with rubber protective sleeves, and the outer side of the rubber protective sleeves is provided with first protective protrusions. When the pontoon moves, it will drive the rubber protective sleeves to move. When the two ends of the pontoon collide with the pile foundation in the cofferdam, they will first contact the rubber protective sleeves. In this way, the impact force is absorbed and buffered by the rubber protective sleeves and the first protective protrusions, thereby reducing the damage to the pile foundation at both ends of the pontoon and improving the protection of the ends of the pontoon during use.

[0011] The present invention is further provided with a rubber protective strip on the outer side of the pontoon, and a second protective protrusion on the outer side of the rubber protective strip. When the pontoon moves and its side comes into contact with the pile foundation in the cofferdam, it will be impacted. The rubber protective strip and the second protective protrusion can absorb the pile foundation force on the side when the pile foundation is in contact, thereby improving the side protection of the pontoon.

[0012] The present invention is further configured such that a liquid detector is installed at the bottom of the inner side of the float, and an alarm is installed above the float. Both the liquid detector and the alarm are powered by a battery and controlled by a controller. The related circuit connection structure is existing known technology and will not be described in detail here. Here, the liquid detector can detect the liquid inside the float. When the float leaks, it can be detected by the liquid detector, and the signal is transmitted to the alarm, which can trigger an alarm. The alarm can be an alarm light, a buzzer, or a combination of both.

[0013] The present invention is further configured such that both the rubber protective sleeve and the rubber protective strip have an installation groove inside, and buffer springs are evenly arranged in the installation groove. By setting buffer springs inside the rubber protective sleeve and the rubber protective strip, the buffering force generated by the float during impact can be further enhanced, thereby further improving the protective effect of the float during use.

[0014] The present invention is further provided that a connecting channel steel is provided between the two floats, and the connecting channel steel is located below the float plate. The connection stability between the two floats can be further improved by the setting of the connecting channel steel, thereby improving the installation stability of the water pump body.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a self-floating mud pump, which has the following beneficial effects:

[0017] 1. This utility model has a connector at the bottom of the water inlet pipe, and a protective mesh is provided on the connector in conjunction with the water inlet pipe. The mesh size of the protective mesh is set to allow mud to pass through, but not to allow large particles such as stones in the mud to pass through, thereby reducing damage to the main body of the water pump.

[0018] 2. This utility model provides rubber protective sleeves at both ends of the pontoon, with a first protective protrusion on the outer side of the rubber protective sleeve. When the pontoon moves, it will drive the rubber protective sleeve to move as well. When the two ends of the pontoon collide with the pile foundation in the cofferdam, they will first contact the rubber protective sleeve. In this way, the rubber protective sleeve and the first protective protrusion absorb and buffer the impact force, thereby reducing the damage to the pile foundation at both ends of the pontoon and improving the protection of the pontoon ends during use. At the same time, this utility model provides a rubber protective strip on the outer side of the pontoon, with a second protective protrusion on the outer side of the rubber protective strip. When the pontoon moves and its side contacts the pile foundation in the cofferdam, it will be impacted. The rubber protective strip and the second protective protrusion can absorb the pile foundation force on the side, improving the side protection of the pontoon.

[0019] 3. This utility model has a liquid detector installed at the bottom of the inner part of the float, and an alarm installed above the float. Both the liquid detector and the alarm are powered by a battery and controlled by a controller. The relevant circuit connection structure is existing known technology and will not be described in detail here. Here, the liquid detector can detect the liquid inside the float. When the float leaks, it can be detected by the liquid detector and the signal can be transmitted to the alarm. The alarm will then sound, providing personnel with information for maintenance. The alarm can be an alarm light, a buzzer, or a combination of both. Attached Figure Description
