Description

Technical Field

[0001] The utility model belongs to the technical field of raw water lifting equipment, and specifically relates to energy-saving horizontal raw water lifting equipment. Background Art

[0002] Raw water lifting equipment is used to lift raw water (usually natural water sources such as rivers, lakes, groundwater, etc.) to a certain height or transport it to other locations. These equipment are very important in water treatment projects, agricultural irrigation, urban water supply, industrial water use and other fields.

[0003] In the current horizontal lift pump connection technology, the traditional way to connect the pump body and the pipeline is to use flange connectors with bolts for fixing. Although this connection method can ensure the stability of the connection, in actual operation, it is necessary to tighten multiple bolts one by one to ensure the sealing between the flange and the pump body or pipeline. The whole process is cumbersome and time-consuming. In addition, since it involves the coordination of multiple parts, this connection method also requires more labor input during assembly and maintenance, increasing labor costs and maintenance difficulties. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an energy-saving horizontal raw water lifting equipment to solve the problem that although the existing connection method proposed in the above background technology can ensure the stability of the connection, in the actual operation process, it is necessary to tighten multiple bolts one by one to ensure the sealing between the flange and the pump body or the pipeline. The whole process is relatively cumbersome and time-consuming. In addition, since it involves the coordination of multiple components, this connection method also requires more labor input during assembly and maintenance, which increases the labor cost and maintenance difficulty.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an energy-saving horizontal raw water lifting equipment, including a pump body and a connecting flange, the input end and the output end of the pump body are fixedly connected with a fixed flange, the outer surface of the fixed flange is fixedly connected with a fixed column, the upper surface of the fixed column is rotatably connected to a limiting column, the side surface of the limiting column is penetrated by a sliding groove, the inside of the sliding groove is slidably connected to a limiting rod, the upper surface of the limiting column is fixedly connected with a handle, and the surface of the connecting flange is penetrated by a limiting hole.

[0006] Preferably, a controller is fixedly connected to the upper surface of the pump body, and a display screen is installed on the controller.

[0007] Preferably, an end cover is installed at one end of the pump body, and a plurality of heat dissipation holes are opened through the surface of the end cover.

[0008] Preferably, a mounting base is fixedly connected to the lower surface of the pump body, and mounting screw holes are provided through four corners of the surface of the mounting base.

[0009] Preferably, the lower surface of the mounting base is provided with an anti-slip layer.

[0010] Preferably, a spring structure is provided between the upper surface of the limiting rod and the inner upper end of the sliding groove.

[0011] Preferably, the limiting rod, the handle and the limiting hole are all of the same shape and size.

[0012] Compared with the prior art, the utility model provides an energy-saving horizontal raw water lifting equipment, which has the following beneficial effects:

[0013] 1. The utility model provides structures such as a limit rod and a limit hole. When connecting the connecting flange and the fixed flange, after the handle is rotated to a position that coincides with the limit hole, the limit column is inserted into the limit hole, and the limit rod is rotated to a position that coincides with the limit hole, and the connecting flange is continued to be pressed in the direction of the fixed flange. After the fixed flange and the connecting flange are in close contact, the limit rod is rotated to a direction perpendicular to the limit hole, thereby realizing the mutual connection between the connecting flange and the fixed flange, effectively avoiding the existing connection method. Although it can ensure the stability of the connection, in the actual operation process, it is necessary to tighten multiple bolts one by one to ensure the sealing between the flange and the pump body or the pipeline. The whole process is relatively cumbersome and time-consuming. In addition, since it involves the cooperation of multiple components, this connection method also requires more labor input during assembly and maintenance, which increases the labor cost and maintenance difficulty.

[0014] 2. The utility model provides a spring structure. When the connecting flange and the fixing flange are combined with each other through the limit rod, the spring structure applies a force toward the lower end to the limit rod, so that the limit rod is pressed downward, and the spring structure provides a buffering force to the limit rod, thereby achieving the purpose of connecting and combining connecting flanges of different thicknesses;

[0015] 3. The utility model achieves the purpose of dissipating the heat inside the pump body by providing the end cover and the heat dissipation holes, thereby ensuring the normal operation of the pump body. By providing the anti-skid layer, when the pump body is installed through the mounting base, the anti-skid layer ensures a large friction between the mounting base and the ground or equipment, thereby preventing the pump body from sliding during installation and causing installation misalignment.

After the fixed flange 9 and the connecting flange 10 are tightly attached, rotate the limiting rod 15 to a direction perpendicular to the limiting hole 11, thereby realizing the mutual connection between the connecting flange 10 and the fixed flange 9, effectively avoiding the existing connection method. Although it can ensure the stability of the connection, in actual operation, it is necessary to tighten multiple bolts one by one to ensure the sealing between the flange and the pump body 1 or the pipeline. The whole process is relatively cumbersome and time-consuming. In addition, since it involves the coordination of multiple components, this connection method also requires more labor input during assembly and maintenance, which increases labor costs and maintenance difficulties.

[0027] In the utility model, preferably, an end cover 7 is installed at one end of the pump body 1, and a plurality of heat dissipation holes 8 are opened through the surface of the end cover 7. The purpose of dissipating the internal heat of the pump body 1 is achieved by setting the end cover 7 and the heat dissipation holes 8, thereby ensuring the normal operation of the pump body 1.

[0032] Working principle and use process of the utility model: When in use, the energy-saving horizontal raw water lifting equipment of the utility model greatly simplifies the flange assembly process through its unique connection method. First, the input end and the output end of the pump body 1 are fixedly connected to the connecting flange 10 through the fixed flange 9. Then, when assembling on the fixed flange 9, the operator rotates the handle 16 to a position that coincides with the limit hole 11, inserts the limit column 13 into the limit hole 11, and then rotates the limit rod 15 to coincide with the limit hole 11, and then presses the connecting flange 10 toward the fixed flange 9, so that the fixed flange 9 and the connecting flange 10 are tightly together. At this time, the operator rotates the limit rod 15 to a direction perpendicular to the limit hole 11, thereby realizing the mutual connection between the connecting flange 10 and the fixed flange 9. The entire process does not require tightening multiple bolts one by one, which saves time and reduces labor intensity.

The spring structure 17 between the limit rod 15 and the slide groove 14 can adapt to the connecting flanges 10 of different thicknesses, making the device more versatile. The limit rod 15, the handle 16 and the limit hole 11 are all the same in shape and size, which further improves the accuracy and convenience of assembly. In general, the utility model provides an efficient, simple and universal raw water lifting equipment with high practical value and market prospects.
