Description

Technical Field

[0001] This utility model relates to the field of water supply pumps, and in particular to an energy-saving high-pressure water supply pump for power plants. Background Technology

[0002] High-pressure feedwater pumps are important equipment commonly used in energy conservation and emission reduction efforts. They are generally driven by either electric motors or steam turbines and are an essential piece of equipment in power plants.

[0003] Chinese patent application number CN202121657654.3 provides a high-pressure water pump. This design is equipped with a push plate and casters, which enable the utility model to move freely and facilitate the handling and transfer of personnel when temporarily called upon. It is also equipped with fixing bolts and fixing pins, which allow the utility model to be fixed in the target position and not move arbitrarily.

[0004] Existing high-pressure feedwater pumps have certain drawbacks in use. First, high-pressure feedwater pumps need to be connected to external systems to carry out their delivery work. However, when high-pressure feedwater pumps operate for extended periods, the lack of secure connections at these connections compromises their stability, affecting the overall stability of the feedwater delivery connection. To address this, we propose an energy-saving high-pressure feedwater pump for power plants. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an energy-saving high-pressure feedwater pump for power plants. By setting a reinforcing sleeve and a positioning ring, the reinforcing sleeve can be positioned outside the connecting structure. At this time, the positioning ring contacts the external component to adjust its position, so that the positioning ring is stably positioned at the outer end of the connecting structure. This allows the high-pressure feedwater pump to be stably connected to the external component even after long-term operation, enabling the high-pressure feedwater pump to transmit and reduce emissions normally, thus improving the practicality of the energy-saving high-pressure feedwater pump in power plants.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An energy-saving high-pressure feedwater pump for power plants includes a main body mechanism, an installation mechanism being movably connected to the inner end of the main body mechanism, and a positioning mechanism being sleeved on the front end of the main body mechanism.

[0008] The positioning mechanism includes assembly rings that are symmetrically distributed. The inner end of each assembly ring is threaded with a fixing member. A reinforcing sleeve is installed at the front end of each assembly ring. The inner end of the reinforcing sleeve is slidably connected with evenly distributed adjusting rods. The front end of each adjusting rod is equipped with a positioning ring, and the outer end of each adjusting rod is fitted with a reinforcing ring.

[0009] By installing a reinforcing sleeve and a positioning ring, the practicality of this energy-saving high-pressure feedwater pump in power plants can be improved.

[0010] Furthermore, a connecting ring is slidably connected to the front side of the reinforcing ring, and the connecting ring is located at the outer end of the adjusting rod.

[0011] By installing the connecting ring, the adjustment rod can drive the positioning ring to adjust more stably.

[0012] Furthermore, the outer end of the connecting ring is provided with a movable groove, the movable groove is located at the inner end of the reinforcing sleeve, and the outer end of the movable groove is provided with an adjustment groove.

[0013] By installing the movable groove, which works in conjunction with the adjustment groove, the adjustment rod can be restricted and guided, making the positioning adjustment of the positioning ring more stable and preventing deviation.

[0014] Furthermore, the main body structure includes an energy-saving water pump body, and the bottom end of the energy-saving water pump body is equipped with symmetrically distributed mounting brackets.

[0015] By installing a mounting bracket, the energy-saving water pump body can operate more stably.

[0016] Furthermore, the front end of the energy-saving water pump body is provided with a connection port, and the bottom end of the mounting bracket is movably connected to an assembly bracket.

[0017] The installation of the assembly frame facilitates the installation and operation of the energy-saving water pump body.

[0018] Furthermore, the inner end of the assembly frame is rotatably connected to a drive assembly, the drive assembly is evenly distributed, and the outer end of each drive assembly is fitted with a symmetrically distributed moving block, the top of the moving block is equipped with a positioning frame.

[0019] By installing a movable block, the energy-saving water pump body can be easily positioned or disassembled.

[0020] Furthermore, a positioning rod is slidably connected to the inner end of the positioning frame, a positioning block is installed at the bottom end of the positioning rod, and an elastic ring is sleeved on the outer end of the positioning rod.

[0021] The installation of a positioning rod improves the ease of maintenance and use of this energy-saving water pump.

[0022] Furthermore, a guide ring is movably connected to the outer end of the elastic ring, and a sliding groove is provided at the outer end of the guide ring, the sliding groove being located at the inner end of the positioning frame.

[0023] By installing a sliding groove, which works in conjunction with a movable guide ring, the moving positioning rod can be guided, ensuring that the positioning rod and positioning block can be disassembled and positioned without any offset.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. By setting a reinforcing sleeve and a positioning ring, the reinforcing sleeve can be positioned outside the connecting structure. At this time, the positioning ring contacts the external component to adjust its position, so that the positioning ring is stably positioned at the outer end of the connecting structure. This allows the high-pressure water pump to be stably connected to the external component even after long-term operation, so that the high-pressure water pump can transmit and reduce emissions normally, thus improving the practicality of the energy-saving high-pressure water pump in power plants.

[0026] 2. By setting up movable blocks, the symmetrically distributed movable blocks can be adjusted in position, allowing the movable blocks to drive the positioning frame to be easily positioned at the outer end of the mounting frame, which facilitates the positioning or disassembly of the energy-saving water pump body.

[0027] 3. By setting positioning rods, multiple positioning rods can be pulled, and the positioning rods can be adjusted in position under the force of the elastic ring. The positioning rods will then drive the positioning block to separate from the mounting bracket, which allows the energy-saving water pump body to be easily disassembled, improving the convenience of maintenance and use of the energy-saving water pump body.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0036] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is an energy-saving high-pressure water pump for power plants, including a main body mechanism 1, an installation mechanism 2 movably connected to the inner end of the main body mechanism 1, and a positioning mechanism 3 sleeved on the front end of the main body mechanism 1.

[0037] The positioning mechanism 3 includes an assembly ring 301, which is symmetrically distributed. The inner end of the assembly ring 301 is threadedly connected to a fixing member 302. A reinforcing sleeve 303 is installed at the front end of the assembly ring 301. The inner end of the reinforcing sleeve 303 is slidably connected to an adjusting rod 304 that is evenly distributed. The front end of each adjusting rod 304 is equipped with a positioning ring 305. A reinforcing ring 306 is sleeved on the outer end of the adjusting rod 304.

[0038] Reference Figure 2-3 As shown, a connecting ring 307 is slidably connected to the front side of the reinforcing ring 306, and the connecting ring 307 is located at the outer end of the adjusting rod 304.

[0039] Reference Figure 3 As shown, the outer end of the connecting ring 307 is provided with a movable groove 308, which is located at the inner end of the reinforcing sleeve 303, and the outer end of the movable groove 308 is provided with an adjustment groove 309.

[0040] By installing the reinforcing sleeve 303, the reinforcing sleeve 303 can be positioned outside the connecting structure. At this time, the positioning ring 305 contacts the external component, and the positioning ring 305 is adjusted in position under the force of the reinforcing ring 306 composed of the adjusting rod 304 and the strong spring component, so that the positioning ring 305 is stably positioned at the outer end of the connecting structure. The connecting ring 307 can move simultaneously with the adjustment of the adjusting rod 304, and is guided by the movable groove 308, so that the adjusting rod 304 drives the positioning ring 305 to adjust more stably, so that the positioning ring 305 is stably positioned at the outer end of the connecting structure, which allows the high-pressure water pump to be stably connected to the external component even after long-term operation.

[0041] Reference Figure 1 As shown, the main body mechanism 1 further includes an energy-saving water pump body 101, and a mounting bracket 102 symmetrically distributed at the bottom end of the energy-saving water pump body 101.

[0042] Reference Figure 1 As shown, the front end of the energy-saving water pump body 101 is provided with a connection port 103, and the bottom end of the mounting bracket 102 is movably connected to an assembly bracket 104.

[0043] By installing symmetrically distributed mounting brackets 102, a support structure can be formed at the bottom of the energy-saving water pump body 101, making the operation of the energy-saving water pump body 101 more stable. The mounting bracket 104 can facilitate the installation and operation of the energy-saving water pump body 101.

[0044] Reference Figure 4-5 As shown, further, the inner end of the assembly frame 104 is rotatably connected to a drive assembly 201, the drive assemblies 201 are evenly distributed, and the outer ends of the drive assemblies 201 are all fitted with symmetrically distributed moving blocks 202, and the top of the moving blocks 202 is equipped with a positioning frame 203.

[0045] Reference Figure 5 As shown, the inner end of the positioning frame 203 is slidably connected to a positioning rod 204, the bottom end of the positioning rod 204 is equipped with a positioning block 205, and the outer end of the positioning rod 204 is fitted with an elastic ring 206.

[0046] Reference Figure 4-5 As shown, further, the outer end of the elastic ring 206 is movably connected to the guide ring 207, and the outer end of the guide ring 207 is provided with a sliding groove 208, which is located at the inner end of the positioning frame 203.

[0047] By installing symmetrically distributed movable blocks 202, they can engage with the drive assembly 201, which consists of a motor and a screw with opposite threads, thereby allowing the movable blocks 202 to be adjusted in position. This enables the movable blocks 202 to drive the positioning frame 203 to be conveniently positioned at the outer end of the mounting frame 102. When the energy-saving water pump body 101 needs to be disassembled, multiple positioning rods 204 are pulled. Under the force of the elastic ring 206, the positioning rods 204 are adjusted in position, and the positioning rods 204 drive the positioning blocks 205 to separate from the mounting frame 102, thus enabling convenient disassembly of the energy-saving water pump body 101 and improving the convenience of maintenance and use of the energy-saving water pump body 101.

[0048] Specific implementation process: When the energy-saving water pump body 101 is used, the drive assembly 201 is started first. The symmetrically distributed moving blocks 202 can interact with the drive assembly 201, which is composed of a motor and a screw with opposite threads, so that the moving blocks 202 can be adjusted in position. The moving blocks 202 can drive the positioning frame 203 to be conveniently positioned at the outer end of the mounting frame 102, thus positioning the energy-saving water pump body 101.

[0049] Next, a pair of assembly rings 301 are installed on the outer end of the connection port 103. At this time, the reinforcing sleeve 303 can be positioned outside the connection structure. The positioning ring 305 contacts the external component. The positioning ring 305 is adjusted in position under the force of the reinforcing ring 306 composed of the adjusting rod 304 and the strong spring component, so that the positioning ring 305 is stably positioned at the outer end of the connection structure. This allows the high-pressure water pump to be stably connected to the external component even after long-term operation, so that the high-pressure water pump can transmit and reduce emissions normally.

[0050] Finally, when the energy-saving water pump body 101 needs to be disassembled, multiple positioning rods 204 are pulled. The positioning rods 204 are adjusted in position under the force of the elastic ring 206. The positioning rods 204 then drive the positioning block 205 to separate from the mounting bracket 102, which allows the energy-saving water pump body 101 to be easily disassembled, improving the convenience of maintenance and use of the energy-saving water pump body 101.
