Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage lifting, and specifically provides a sewage lifting device. Background Technology
[0002] Wastewater lifting equipment, a type of wastewater treatment device used in low-level drainage scenarios such as basements and ships, typically consists of a collection tank, a wastewater pump, a level control system, and piping components. Its core function is to lift wastewater to the municipal sewer network or a designated discharge point via pumping. In existing technologies, the ground fixing method for the collection tank of wastewater lifting equipment generally adopts an expansion bolt anchoring structure. This involves pre-drilling holes in the ground, embedding expansion bolts, and then using the threaded connection between the bolts and the equipment base to achieve fixation.
[0003] However, the above-mentioned fixing method has significant drawbacks: First, the installation process requires precise positioning and drilling of the ground, and at least two expansion bolt holes must be aligned simultaneously. Due to the large size and weight of the equipment, operators need to repeatedly adjust the equipment position to meet the hole alignment requirements, resulting in low installation efficiency. Second, the fixing effect of the expansion bolts is significantly affected by the ground material (such as the strength of concrete, the adhesion of tiles / epoxy flooring), and insufficient anchoring force is prone to occur under non-ideal working conditions. Vibration during equipment operation may cause the bolts to loosen, posing a risk of equipment displacement or even overturning. In addition, when the equipment needs to be replaced or maintained, the disassembly process requires loosening the expansion bolts one by one. When the operating space is limited, tools are difficult to use, further increasing maintenance costs.
[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the above-mentioned technical problems and address the inconvenience of fixing existing sewage lifting equipment on the ground.
[0006] This utility model provides a sewage lifting device, comprising: a main body of the device, wherein locking recesses are provided on opposite sides near the bottom; a base, which is disposed on a fixed plane and provided with an installation groove; a fixing assembly, which includes a threaded rod and two fixing heads, one end of the two fixing heads being slidably connected to the installation groove, and the other end of the two fixing heads being provided with locking protrusions, the locking protrusions being configured to be inserted into the locking recesses; the threaded rod being disposed in the installation groove, the threaded rod being threadedly connected to the two fixing heads, and the threaded rod being configured to allow the two fixing heads to move in a direction that clamps the main body of the device.
[0007] By employing the above technical solution, the two fixing heads are synchronously clamped to the main body of the equipment via a threaded rod, simplifying the method of fixing the main body. The interlocking design of the protruding and recessed locking mechanisms is compatible with different ground materials. The fixing heads can be released by rotating the threaded rod in the opposite direction, without the need for special tools, thus shortening maintenance and disassembly time.
[0008] In a specific embodiment of the above-mentioned sewage lifting equipment, a mounting base is provided in the mounting groove, and the threaded rod is rotatably connected to the mounting base.
[0009] When the above technical solution is adopted, the mounting base is set to facilitate the fixing of the threaded rod position, so that the two fixing heads will not slide arbitrarily in the mounting groove.
[0010] In a specific embodiment of the above-mentioned sewage lifting equipment, the mounting base is located at the middle position along the length of the mounting groove, the mounting base is provided with a rotating hole, a bearing is provided in the rotating hole, and the threaded rod passes through the bearing and is connected to the bearing.
[0011] In a specific embodiment of the above-mentioned sewage lifting equipment, the snap-fit protrusion is wedge-shaped, and the cross-section of the snap-fit protrusion gradually decreases in the direction toward the main body of the equipment. The snap-fit protrusion is configured to enable the main body of the equipment to press against the base.
[0012] In a specific embodiment of the above-mentioned sewage lifting equipment, a rotating part is provided at one end of the threaded rod, and the rotating part is configured to facilitate the rotation of the threaded rod.
[0013] In a specific embodiment of the above-mentioned sewage lifting equipment, the rotating part is a hexagonal block.
[0014] When the above technical solution is adopted, the hexagonal block is compatible with standard wrenches or power tools, making it more convenient to rotate the threaded rod.
[0015] In a specific embodiment of the above-mentioned sewage lifting equipment, the portion of the fixing head disposed within the mounting groove is a long, narrow sliding strip, and the sidewall of the sliding strip is in contact with the inner sidewall of the mounting groove.
[0016] When the above technical solution is adopted, the sliding strip fits against the side wall of the mounting groove, ensuring that the snap-fit protrusion is accurately inserted into the snap-fit recess.
[0017] In a specific embodiment of the above-mentioned sewage lifting equipment, the fixing head further includes a connecting block for connecting the sliding strip and the snap-fit protrusion. The base is provided with a first notch extending along the length direction of the mounting groove and communicating with the mounting groove. The lower end of the snap-fit recess is provided with a second notch extending along the length direction of the snap-fit recess and communicating with the snap-fit recess. The connecting block is configured to pass through the first notch and the second notch.
[0018] In a specific embodiment of the above-mentioned sewage lifting equipment, a positioning protrusion is provided at the bottom of the main body of the equipment, and a positioning hole is provided on the base. The positioning protrusion is configured to be able to be inserted into the positioning hole.
[0019] When the above technical solution is adopted, the positioning protrusion is inserted into the positioning hole of the base to achieve rapid coarse positioning of the main body of the equipment.
[0020] In a specific embodiment of the above-mentioned sewage lifting equipment, the end of the positioning protrusion away from the main body of the equipment is rounded.
[0021] When the above technical solution is adopted, the rounded corners reduce the frictional resistance during installation and avoid scratching the base surface, while also facilitating the insertion of the positioning protrusion into the positioning hole. Attached Figure Description

[0031] It should be understood that the terms "upper," "lower," and "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, "a plurality of" in this application means at least two.
[0032] like Figures 1-5 As shown, to solve the problem of inconvenient fixing of existing sewage lifting equipment on the ground, this utility model provides a sewage lifting equipment, including: a main body 1, with snap-fit recesses 11 on its two opposite sides near the bottom; a base 2, which is set on a fixed plane and has an installation groove 22; a fixing component 3, which includes a threaded rod 31 and two fixing heads 32, one end of the two fixing heads 32 being slidably connected to the installation groove 22, and the other end of the two fixing heads 32 being provided with snap-fit protrusions 321, which are designed to be inserted into the snap-fit recesses 11; the threaded rod 31 is set in the installation groove 22 and is threadedly connected to the two fixing heads 32, and the threaded rod 31 is designed to allow the two fixing heads 32 to move in the direction of clamping the main body 1. In this way, the threaded rod 31 drives the two fixing heads 32 to clamp the main body 1 simultaneously, simplifying the fixing method of the main body 1. The insertion design of the snap-fit protrusions 321 and the snap-fit recesses 11 is compatible with different ground materials. The fixing head 32 can be loosened by rotating the threaded rod 31 in the opposite direction, without the need for special tools, thus shortening the maintenance and disassembly time.
[0033] like Figure 1 As shown, in one or more embodiments, the sewage lifting equipment includes a main body 1, a base 2, and a fixing component 3.
[0034] like Figure 2 As shown, in one or more embodiments, the device body 1 has a snap-fit recess 11 near its bottom on both the side facing outwards towards the paper and the side facing inwards towards the paper. The extension lines of the two snap-fit recesses 11 along their length coincide. Alternatively, the two snap-fit recesses 11 may be in other relative positions. A second notch 12 is provided on the lower side of each snap-fit recess 11 along its length. It should be noted that the second notch 12 is not mandatory; those skilled in the art can choose whether to provide the second notch 12 and its specific structure based on the specific application scenario, or the second notch 12 may not be provided.
[0035] like Figure 3 As shown, in one or more embodiments, the base 2 is disposed on a fixed plane. This fixed plane refers to a fixed installation position, typically the ground. The base 2 is fixed to the ground by screws or welding. A corresponding recess is provided on the ground so that the lower end of the base 2 is flush with the ground. Thus, fixing the base 2 to the ground allows for fixing in more locations compared to directly fixing the equipment body 1 to the ground. The base 2 is smaller and easier to operate than fixing the equipment body 1 directly. Alternatively, the base 2 can also be partially recessed downwards, with the recessed portion contacting the ground. When fixed with expansion screws, the nut portion is located within the recess and does not affect the fixing of the equipment body 1. It should be noted that the method of fixing the base 2 to the ground is existing technology and will not be described further here. In one or more embodiments, a mounting groove 22 is provided on the lower side of the base 2 at approximately the middle position. The base 2 has a first notch extending along the length of the mounting groove 22 and communicating with it. A mounting seat 221 is provided within the mounting groove 22. Mounting base 221 is located at the middle position along the length of mounting groove 22. Mounting base 221 has a rotating hole, and a bearing is installed in the rotating hole. It should be noted that the installation of mounting base 221 is not mandatory, and those skilled in the art can choose the structure of mounting base 221 based on specific application scenarios. Of course, mounting base 221 can also be omitted.
[0036] like Figures 3-5As shown, in one or more embodiments, the fixing component 3 includes a threaded rod 31 and two fixing heads 32. The threaded rod 31 is disposed within the mounting groove 22, and its approximate center position along its length is fixedly connected to the inner ring of the bearing in the rotating hole, thereby preventing the threaded rod 31 from moving along the length of the mounting groove 22. In one or more embodiments, a rotating part 311 is provided at one end of the threaded rod 31, which is configured to facilitate rotation of the threaded rod 31. The rotating part 311 is a hexagonal block. The hexagonal block is compatible with a standard wrench or power tool, making it more convenient to rotate the threaded rod 31. Alternatively, the rotating part 311 can also be a ring or the like, as long as it facilitates the rotation of the threaded rod 31 using a tool; of course, the rotating part 311 may not be provided at all.
[0037] like Figures 3-5 As shown, in one or more embodiments, the number of fixing heads 32 is two. The two fixing heads 32 are located on both sides of the device body 1, and are used to fix the device body 1 to the base 2. Each fixing head 32 includes a snap-fit protrusion 321, a connecting block 323, and a sliding strip 322. Figure 4 As shown, the snap-fit protrusion 321 is wedge-shaped and divided into two parts: the right side is the first protrusion, and the left side is the second protrusion. The first protrusion is a platform with a cross-sectional area that gradually increases from right to left. The first protrusion facilitates insertion into the snap-fit recess 11. The second protrusion is also a platform with a cross-sectional area that gradually increases from right to left. The upper side of the second protrusion is perpendicular to the bottom surface, and the lower side is inclined. The second protrusion causes the device body 1 and the base 2 to press against each other when inserted into the snap-fit recess 11, making the connection between the device body 1 and the base 2 more stable. It should be noted that the first and second protrusions are not mandatory. Those skilled in the art can choose whether to set the first and second protrusions and their specific structures based on the specific application scenario. As long as the cross-section of the snap-fit protrusion 321 gradually decreases in the direction towards the device body 1, it is sufficient to press the device body 1 tightly against the base 2.
[0038] like Figure 4 As shown, in one or more embodiments, the sliding bar 322 has an elongated shape, and its sidewall is fitted against the inner sidewall of the mounting groove 22. Alternatively, the sliding bar 322 may not be fitted against the mounting groove 22. A threaded hole is provided within the sliding bar 322 along its length, through which it is threadedly connected to the threaded rod 31.
[0039] like Figure 4As shown, in one or more ways, the connecting block 323 is used to connect the sliding bar 322 and the snap-fit protrusion 321. Specifically, the lower end of the connecting block 323 is connected to the left end of the sliding bar 322, and the upper end of the connecting block 323 is connected to the left end of the snap-fit protrusion 321. When the snap-fit protrusion 321 is inserted into the snap-fit recess 11, the connecting block 323 passes through the first notch and the second notch 12.
[0040] like Figure 3 As shown, in one or more embodiments, the base 2 is provided with a plurality of circular positioning holes 21, which are used to position the device body 1. It should be noted that the provision of positioning holes 21 is not mandatory. Those skilled in the art can choose whether to provide positioning holes 21 and the specific structure of the positioning holes 21 based on the specific application scenario. Of course, positioning holes 21 can also be omitted.
[0041] In one or more embodiments, the bottom of the device body 1 is provided with positioning protrusions, which correspond one-to-one with positioning holes 21. The end of the positioning protrusion furthest from the device body 1 is rounded. This rounded corner reduces frictional resistance during installation and prevents scratching the surface of the base 2, while also facilitating insertion of the positioning protrusion into the positioning hole 21. Alternatively, the number of positioning protrusions may be less than the number of positioning holes 21. Alternatively, the end of the positioning protrusion furthest from the device body 1 may not have a rounded corner. Of course, positioning protrusions may also be omitted entirely.
[0042] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.
[0043] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
