Description

Technical Field

[0001] This utility model belongs to the technical field of water intake equipment for water conservancy projects, specifically relating to a multi-stage rocker arm water conveying device for a water intake pump ship. Background Technology

[0002] The steel-armed trestle-type water intake pumpboat is a new type of water intake equipment, mainly used for water intake projects along rivers, lakes, and reservoirs. Connected by a steel-armed trestle, the pumpboat can adapt to changes in water level, maintaining the pump's suction inlet at a fixed depth below the water surface, thus ensuring the quality of the water intake and the normal operation of the pump. This design not only improves the reliability of water intake but also significantly reduces construction and maintenance costs.

[0003] The length of a steel swing arm pier is determined by the distance between the water intake point and the shore support. In practical applications, there are often situations where the distance is long and the pipe diameter is small (i.e., the pipe is long and thin). In such cases, the rigidity of the swing arm pier often fails to meet the design requirements. When faced with changes in water level, the pipe is prone to breakage due to stretching deformation, or manual adjustment is required. Some are connected with flexible hoses, but they are easily damaged by water flow impact, swinging and friction. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed multi-stage rocker arm water conveying device for a water intake pumping vessel in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-stage rocker arm water conveyance device for a water intake pumping vessel includes a water intake pumping vessel, a multi-stage steel rocker arm trestle, and a support rocker arm assembly.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1: As Figure 1 - Figure 2 As shown, a multi-stage rocker arm water conveying device for a water intake pumping vessel includes a water intake pumping vessel 1, a multi-stage steel rocker arm trestle 2, a rocker arm support assembly 3, a shore support column 4, and a third rotary joint 5. The components are connected by a sealed rotation to form a continuous water conveying channel.

[0025] like Figure 1 - Figure 3As shown, the water intake pump vessel 1 includes a hull 101 that floats on the water surface. The hull 101 adopts a steel catamaran structure with a buoyancy chamber at the bottom to ensure stable floating at different water levels. A canopy 102 is fixedly installed on the top of the hull 101. The canopy 102 is a combination of a steel frame structure and a rainproof color steel plate, which can shield the vessel from rain and sun and protect the equipment on the top of the hull. A warning light 103 is fixedly installed on the top of the canopy 102, which is lit at night or in inclement weather to warn passing vehicles. The function of the vessel: A guide rail 104 is fixedly installed at the upper end of the inner side wall of the canopy 102. The guide rail 104 is laid along the length of the canopy, and an electric trolley 105 is slidably connected to its outer side wall. An anchor 106 is installed at the bottom of the electric trolley 105. When the water intake pump vessel 1 needs to be fixed in position or the anchor point needs to be adjusted, the electric trolley 105 can slide along the guide rail 104 to the designated position, and the anchor chain is lowered through the anchor 106 to achieve the positioning of the hull and avoid the hull from shifting due to the impact of water flow.

[0026] like Figure 3 As shown, a water pump 112 is fixedly installed on the top of the hull 101. The water pump 112 is a centrifugal water pump with a rated head of 50m and a flow rate of 200m³ / h. 3 The pump 112 has an input end connected to a suction pipe 111 via a flange. The other end of the suction pipe 111 extends 3-5 meters underwater to ensure the water intake depth and avoid sucking in floating objects. The output end of the pump 112 is connected to a pump control valve 110 via a flange. The pump control valve 110 is an electric butterfly valve, which can be remotely controlled to adjust the opening degree and achieve precise control of the water delivery. The other end of the pump control valve 110 is connected to a connecting pipe 109 via a pipeline. The connecting pipe 109 is a seamless steel pipe with a diameter of 300mm, and its other end is connected to... There is a water collection pipe 108, which is a ring-shaped steel pipe and is fixedly installed on one side of the top of the hull 101. It can collect the water output from multiple water pumps 112. If a single pump meets the requirements, only one pump needs to be connected. The other end of the water collection pipe 108 is connected to the first rotary joint 107 through a flange. The first rotary joint 107 is fixedly installed on one side of the top of the hull 101 and adopts a mechanical seal structure. It can achieve 360° rotation and maintain water supply seal, providing rotational adaptability for subsequent connection with the multi-stage steel rocker arm bridge 2.

[0027] like Figure 1 and Figure 2As shown, the multi-stage steel rocker arm trestle 2 includes a primary steel rocker arm trestle 202 and a secondary steel rocker arm trestle 203. Both are made of Q355B steel truss structure, which is lightweight and has a high load-bearing capacity. The surface is treated with hot-dip galvanizing for corrosion protection, extending its service life. Both the primary steel rocker arm trestle 202 and the secondary steel rocker arm trestle 203 have connecting water supply rocker arms 201 on their side walls. The connecting water supply rocker arms 201 are seamless steel pipes, fixedly connected to the rocker arm trestle truss via pipe clamps and supports. The primary steel rocker arm trestle... One end of the water delivery rocker arm 201 on the arm trestle 202 is sealed and rotatably connected to the first rotary joint 107 via a flange, and the other end is sealed and rotatably connected to the host rocker arm assembly 3 via a flange, so as to realize the transportation of water from the water intake pump boat 1 to the host rocker arm assembly 3; one end of the water delivery rocker arm 201 on the secondary steel rocker arm trestle 203 is sealed and rotatably connected to the host rocker arm assembly 3 via a flange, and the other end is sealed and rotatably connected to the third rotary joint 5 via a flange, so as to realize the transportation of water from the host rocker arm assembly 3 to the shore.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the managed rocker arm assembly 3 includes a managed floating vessel 301 that floats on the water surface. The managed floating vessel 301 is a steel box structure filled with foam buoyancy material to ensure stable floating on the water surface and anti-capsulation capability. Mounting seats 303 are fixedly installed on both sides of the top of the managed floating vessel 301. The mounting seats 303 are steel welded structures used to fix the second rotary joint 304.

[0029] like Figure 4 As shown, the two mounting bases 303 are connected by a water collection pipe (not labeled), a steel pipe that can guide the water input from one side of the second rotary joint 304 to the other side of the second rotary joint 304. The top of each of the two mounting bases 303 is fixedly connected to a second rotary joint 304, which also adopts a mechanical seal structure and has bidirectional rotation capability. The output end of one second rotary joint 304 is sealed and rotatedly connected to the water supply rocker arm 201 on the first-stage steel rocker arm bridge 202 through a flange, and the output end of the other second rotary joint 304 is sealed and rotatedly connected to the water supply rocker arm 201 on the second-stage steel rocker arm bridge 203 through a flange, realizing the diversion and transportation of water between the first-stage and second-stage rocker arm bridges, while adapting to the rocker arm angle offset caused by water level changes.

[0030] like Figure 1 and Figure 2As shown, the bank support 4 is a steel column, fixed to the bank ground at the bottom by a concrete foundation, and a third rotary joint 5 is fixedly installed at the top. The input end of the third rotary joint 5 is sealed and rotated with the water supply rocker arm 201 on the secondary steel rocker arm trestle 203 through a flange, and the output end is connected to the water supply pipeline of the bank user, such as the urban water supply network or industrial water pipeline, through a flange, to complete the final delivery of water from the device to the user. The setting of the third rotary joint 5 can adapt to the angle change of the secondary steel rocker arm trestle 203 caused by water level fluctuations, ensuring the sealing and stability of the connection with the user's pipeline.

[0031] It should be noted that, when using this multi-stage rocker arm water conveying device for a water intake pumping vessel, the water pump 112 on the hull 101 is started, and external water is drawn into the water pump 112 through the suction pipe 111. The water pump 112 pressurizes the water and delivers it to the water pump control valve 110.

[0032] Water collection: By adjusting the opening of the water pump control valve 110, the water flow rate is controlled. The water flows into the water collection pipe 108 through the connecting pipe 109. The water collection pipe 108 collects the water and then delivers it to the first rotary joint 107.

[0033] First-stage rocker arm conveying: The first rotary joint 107 conveys water to the connecting water delivery rocker arm 201 on the first-stage steel rocker arm trestle 202. Since the first rotary joint 107 can rotate freely, the first-stage steel rocker arm trestle 202 can adjust its angle with slight offset of the hull 101 or changes in water level, while maintaining a water delivery seal.

[0034] Transfer via managed floating vessel: Water flows into one of the second rotary joints 304 on managed floating vessel 301 through the water delivery rocker arm 201 connected to the first-stage steel rocker arm trestle 202, and then flows to the other second rotary joint 304 through the water collection pipe. Managed floating vessel 301 floats on the water surface and can move synchronously with the rise and fall of the water level, ensuring that the two-stage rocker arm trestle remains connected at all times.

[0035] Secondary rocker arm and shore delivery: The second rotary joint 304 delivers water to the connecting water delivery rocker arm 201 on the secondary steel rocker arm trestle 203. The secondary steel rocker arm trestle 203 delivers water to the third rotary joint 5 through the connecting water delivery rocker arm 201, and finally flows into the shore user's pipeline through the third rotary joint 5, completing the entire water delivery process.

[0036] During operation, if the water level rises or falls, the floating pontoon 301 will rise and fall synchronously with the water level. The first and second steel rocker arm trestle 2 adjusts the angle by rotating the rotary joint to always maintain the continuity and sealing of the water supply channel. The electric trolley 105 and the anchor 106 can adjust the position of the hull 101 according to the water flow to ensure stable water intake. The warning light 103 will be lit under special working conditions to ensure the safe operation of the device.

[0037] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
