Description

Technical Field

[0001] The present application relates to the technical field of sewage discharge equipment, and in particular to a quick installation structure of a submersible sewage pump and an installation method thereof. Background Art

[0002] Submersible sewage pump is a submersible sewage pump, which is particularly suitable for conveying liquids containing hard solids, fibers, and particularly dirty, sticky and slippery liquids.

[0003] Submersible sewage pumps obviously have the following advantages:

[0004] 1. Compact structure and small footprint. Since the submersible sewage pump works under the liquid, it can be directly installed in the sewage pool. There is no need to build a special pump room to install the pump and machine, which can save a lot of land and infrastructure costs.

[0005] 2. Easy installation and maintenance. Small pumps can be installed freely, and large pumps are generally equipped with automatic coupling devices for automatic installation, which makes installation and maintenance quite convenient.

[0006] 3. Long continuous operation time. Since the sewage pump and the motor are coaxial, the shaft is short, and the rotating parts are light, the load (radial) on the bearing is relatively small, and the service life is much longer than that of ordinary pumps.

[0007] 4. There is no cavitation damage and water diversion. Especially the latter point brings great convenience to the operators.

[0008] Some existing traditional submersible sewage pumps are composed of a base, a submersible sewage pump, and a coupler. The base is generally fixed in the sewage pool in advance, and the submersible sewage pump needs to be sunk into the pool to connect with the coupler. Since the water quality is often poor, if manual diving is used for direct connection, the submersible sewage pump needs to be assisted to dive first, and then connected with the coupler. Before connection, it must be docked and aligned. However, personnel cannot perceive the underwater situation when diving into sewage, so docking and alignment are relatively difficult. Manual connection is difficult, and if the installation is not in place, a leak will occur due to poor sealing. Therefore, an auxiliary device is needed to assist manual alignment of the submersible sewage pump and the coupler to improve work quality and efficiency. Summary of the invention

[0009] In order to solve the installation problems of traditional submersible sewage pumps, reduce the difficulty of personnel operation, and improve the installation quality and efficiency of submersible sewage pumps, the present application provides a submersible sewage pump quick installation structure and an installation method thereof.

During the cooperation between the guide block and the two inclined plates, the coupler flange continuously moves toward the water inlet port of the coupler. When it falls to the lowest end, the end face of the coupler flange close to the coupler is butted against the end face of the water inlet port of the coupler, and the sealing ring is sealed against the end face of the water inlet port of the coupler to achieve automatic alignment and docking.

The guide rod has a guiding effect on the guide block, so that the coupler flange and the submersible sewage pump can be lifted and lowered along the guide rod and automatically aligned to prevent deviation. When the guide block is lifted and lowered along the guide rod, the positive projection in the horizontal plane direction between the end face of the sealing ring close to the coupler and the end face of the water inlet port of the coupler is set as a gap.

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The following is combined with Figures 1 to 8 This application is described in further detail.

[0054] The embodiments of the present application disclose a quick installation structure of a submersible sewage pump and an installation method thereof.

[0055] Reference Figures 1 to 8 The quick installation structure of the submersible sewage pump includes: a base 1 and a guide quick-connect assembly.

[0056] One end of the base 1 is used to install the coupler 17, and a support frame 2 is also installed on the base 1 at this end. The coupler 17 and the support frame 2 are fixedly connected by bolts, and the top of the support frame 2 is exposed above the water surface, which is convenient for personnel to see the operation clearly.

[0057] The guide quick-connect assembly comprises a coupler flange 3, a guide rod 7, and a docking seat.

[0058] The two ends of the coupler flange 3 are used to connect the water outlet port of the submersible sewage pump 16 and the water inlet port of the coupler 17 respectively. The top of the coupler flange 3 is close to one end of the coupler 17. The integral structure is provided with a rib plate 4. The integral structures on both sides of the rib plate 4 are provided with guide blocks 5. The guide block 5 is a cylinder. The axial direction of the cylinder is arranged along the two sides of the rib plate. A claw 6 is provided on the outer side of the guide block 5. The claw 6 has two claws, which are arranged horizontally symmetrically. A circular arc groove is formed between the two claws. Figure 7 , 8, starting from the horizontal middle position of the arc groove, the size of the arc groove gradually increases towards the upper and lower ends of the arc groove.

[0059] There are two guide rods 7, which are arranged vertically and in parallel at intervals. The guide rods 7 can be stainless steel tubes. The top ends of the two guide rods 7 are arranged above the water surface. The tops of the two guide rods 7 are installed at both ends of a coupler bracket 8. The middle end of the coupler bracket 8 is fixedly connected to the top end of the support frame 2 by bolts.

[0060] The docking seat is arranged at the top of the water inlet port of the coupler 17, and guide rod seats 9 are protruding on both sides of the docking seat, which is shown as an integrated structure. The bottom ends of the two guide rods 7 are respectively fixedly mounted on the guide rod seats 9 on both sides. Two inclined plates 10 are arranged on the docking seat along the radial direction of the water inlet port of the coupler 17, and the two inclined plates 10 are distributed at a V-shaped angle. On the inclined plate 10 close to the water inlet port of the coupler 17, a vertical plate 11 is vertically arranged, and the vertical plate 11 and the inclined plate 10 are designed as an integrated structure. The vertical plate 11 is arranged to provide a preliminary guiding effect on the guide block 5.

[0061] The guide block 5 is slidably matched with the guide rod 7 through the claw 6. The guide block 5 is lifted and lowered along the guide rod 7. The guide block 5 is located between the two inclined plates 10 in the up and down directions. The orthographic projection of the guide block 5 in the horizontal plane direction is located between the two inclined plates 10. When the guide block 5 is lifted and lowered along the guide rod 7, the orthographic projection in the horizontal plane direction forms a gap between the end face of one end of the coupler flange 3 close to the coupler 17 and the end face of the water inlet port of the coupler 17. When the guide block 5 falls between the two inclined plates 10, the coupler flange 3 and the water inlet port of the coupler 17 are butt-jointed and sealed.

[0062] A ramp 10 can also be provided on the docking seat, so that the ramp 10 away from the water inlet port of the coupler 17 can be removed. When the guide block 5 falls to the height of the ramp 10, the guide block 5 abuts against the ramp 10 close to the water inlet port of the coupler 17. Under the guiding action of the ramp 10, the guide block 5 continues to move downward along the guide rod 7, and has a tendency to tilt and move in the direction away from the water inlet port of the coupler 17, so that the coupler flange 3 has a tendency to tilt and move in the direction close to the water inlet port of the coupler 17, so that the coupler flange 3 and the coupler 17 are firmly docked.

[0063] The guide block 5 is configured as a cylinder, that is, an arc-shaped design, which can better cooperate with the two inclined plates 10 and provide better guide and limit cooperation.

[0064] The inner diameter of the axial fit between the clamping claw 6 and the guide rod 7 is larger than the outer diameter of the guide rod 7, that is, the inner diameter of the arc groove formed between the two clamping claws is larger than the outer diameter of the guide rod 7. This design allows a movable margin between the clamping claw 6 and the guide rod 7, that is, the guide block 5 has a movable margin relative to the guide rod 7, so that the guide block 5 can better cooperate with the two inclined plates 10, and under the guidance of the two inclined plates 10, automatic alignment is achieved.

[0065] The coupler bracket 8 is at the top of the guide rod 7, and an opening 12 is provided on the coupler bracket 8, the contour of which is the same as that of the guide block 5 when viewed from above. That is, when the guide block 5 starts to descend from the top of the guide rod 7, the guide block 5 must first pass through the opening 12 on the coupler bracket 8 before it can cooperate with the guide rod 7, thereby playing a docking auxiliary guiding role in the lifting and lowering movement of the guide block 5.

[0066] The docking seat is arranged at the top of the water inlet port of the coupler 17. The position between the docking seat and the coupler 17 is determined. At the same time, the bottom end of the guide rod 7 is also supported and fixed to ensure the stability of the guide rod 7, which is beneficial to improving the docking quality between the coupler flange 3 and the water inlet port of the coupler 17.

[0067] A sealing groove 13 is provided at one end of the coupler flange 3 near the water inlet port of the coupler 17. The sealing groove 13 is divided into two ends with different inner diameters. The inner diameter of the end near the water inlet port of the coupler 17 is smaller than the inner diameter of the end away from the water inlet port of the coupler 17. A sealing ring 14 is installed in the sealing groove 13. The inner diameter of the end of the sealing ring 14 near the water inlet port of the coupler 17 is larger than the inner diameter of the end away from the water inlet port of the coupler 17. The structural design of the sealing groove 13 can better limit and fix the sealing ring 14 to prevent the sealing ring 14 from coming out. When the guide block 5 falls between the two inclined plates 10, the sealing ring 14 on the coupler flange 3 is butt-sealed with the water inlet port of the coupler 17, and can better contact and resist the water inlet port of the coupler 17 to ensure the sealing effect.

[0068] Through the setting of the base 1, the coupler 17 is more convenient to install and fix. The guide rod 7 has a guiding effect on the guide block 5. The top of the guide rod 7 is exposed to the water surface. When the guide block 5 is aligned with the guide rod 7, the personnel can see the alignment clearly, which is convenient for alignment operation, so that the coupler flange 3 and the submersible sewage pump 16 can be lifted and lowered along the guide rod 7, and automatically aligned to prevent deviation. When the guide block 5 is lifted and lowered along the guide rod 7, the sealing ring 14 is close to the end face of the coupler 17 and the end face of the water inlet port of the coupler 17. The positive projection in the horizontal plane direction is set in a gap. Through the setting of the two inclined plates 10 on the docking seat, when the guide block 5 drops to the bottom position, the two inclined plates 10 can automatically align the guide block 5, so that the coupler flange 3 can be automatically aligned and docked with the water inlet port of the coupler 17, so that the sealing ring 14 is in contact with the coupler 17 all around, and squeezed between the coupler flange 3 and the coupler 17 to form a seal to complete the docking. It is only necessary to control the lifting and lowering of the submersible sewage pump 16, and no longer needs to be manually aligned and docked.

[0069] In a submersible sewage pump, the submersible sewage pump 16 is generally arranged vertically with the water inlet facing downward. At the top connecting part 15 of the submersible sewage pump 16, a fixed handle is connected to the submersible sewage pump 16, and the fixed handle is connected by a rope or a chain, which is a flexible connection method. Because during the lifting and lowering process of the submersible sewage pump, especially during the docking process, the submersible sewage pump needs to move a margin to ensure that the sealing ring 14 can be abutted against and squeezed against the end face of the water inlet port of the coupler 17 to ensure the docking sealing efficiency. Therefore, a flexible connection method is best to pull the submersible sewage pump 16 up or down. Through the setting of the connecting part 15, the submersible sewage pump 16 can be quickly connected, and the submersible sewage pump can be lifted and lowered to improve the convenience of operation.

[0070] The installation method of the submersible sewage pump quick installation structure includes:

[0071] Step 1: Install the coupler 17 and the support frame 2 on the base 1;

[0072] Step 2: Connect the coupler bracket 8 to the top end of the guide rod 7, install the bottom end of the guide rod 7 on the docking seat, and then install the coupler bracket 8 on the support frame 2;

[0073] Step 3: Sink the base 1 into the water and fix it;

[0074] Step 4: Connect and fix the coupler flange 3 to the water outlet port of the submersible sewage pump 16;

[0075] Step 5: Control the lifting and lowering of the submersible sewage pump through the connecting part 15 provided on the submersible sewage pump, gradually lower the submersible sewage pump, align the guide block with the opening on the coupler bracket and lower it, continue to lower it, the guide block lowers along the guide rod until the guide block drops to the docking seat, continue to lower it, the guide block cooperates with the two inclined plates, the guide block descends along the two inclined plates until it lands at the lowest end, in the process of the guide block cooperating with the two inclined plates, the coupler flange continuously moves toward the water inlet port of the coupler, when it falls to the lowest end, the end face of the coupler flange 3 close to the coupler 17 is butted against the end face of the water inlet port of the coupler 17, the sealing ring 14 is sealed against the end face of the water inlet port of the coupler 17, and automatic alignment and docking are achieved.

[0076] The installation method of the submersible sewage pump 16 is simple. By adopting the installation method, the submersible sewage pump 16 can quickly and automatically complete the docking installation, saving time and labor, and can improve the installation sealing performance of the submersible sewage pump 16 and reduce the occurrence of leakage.
