Description

Technical Field

[0001] This application belongs to the field of wastewater treatment, specifically a mounting bracket for a submersible sewage pump used in a tailrace tank. Background Technology

[0002] A submersible sewage pump is a type of pump specifically designed to discharge sewage containing impurities such as solid particles, fibers, and sludge. It uses the centrifugal force generated by the high-speed rotation of the impeller to draw solid particles and liquid from the sewage into the pump chamber, and then discharges the sewage under pressure through the pressure chamber.

[0003] Currently, wastewater treatment plants often purchase submersible pumps to treat effluent. However, existing submersible pumps often require the installation location to be set before or during construction. For some wastewater treatment plants, there may be differences between the submersible pumps intended to be purchased before or after construction and the actual submersible pumps purchased afterward, or there may be situations where additional submersible pumps are desired after construction. Therefore, it is often necessary to add additional submersible pump mounting brackets on site.

[0004] In the use of existing submersible sewage pump mounting brackets, since the submersible sewage pump is fixed relative to the bracket, it is often necessary to lower the water level to expose the submersible sewage pump to the water surface before maintenance can be carried out. However, when lowering the water level, water retention issues often need to be considered, which is time-consuming and labor-intensive. Therefore, it is necessary to design a submersible sewage pump mounting bracket for use in tailrace tanks to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by using a submersible pump moving mechanism to move the submersible pump up and down, enabling the submersible pump to move above the liquid surface. This design provides a submersible pump mounting bracket for use in tailrace tanks, solving the problem of needing to lower the water level during submersible pump maintenance.

[0027] Reference Figures 1-8 A mounting bracket for a submersible sewage pump in a tailrace tank includes four columns 1, a lower crossbeam 2, a top main beam 3, a top secondary beam 4, a flange plate 5, and a mounting plate 6. The four columns 1 are arranged in a 2x2 rectangle. The columns 1 are made of C10 stainless steel. The bottom ends of the four columns 1 are fixedly connected to the upper surface of the flange plate 5, and the top ends of the columns 1 are fixedly connected to the lower surface of the top main beam 3. The four top main beams 3 are also made of C10 stainless steel, and their ends are fixedly connected to the top ends of two adjacent columns 1. The sides of the two adjacent top main beams 3 are connected to the top secondary beam 6. The ends of beam 4 are fixedly connected. The distance between the left top secondary beam 4 and the left top main beam 3 is the same as the distance between the right top secondary beam 4 and the right top main beam 3. The distance between the two top secondary beams 4 is greater than the width of the submersible pump. The sum of the distance between the left top secondary beam 4 and the left top main beam 3 and the distance between the two top secondary beams 4 is greater than or equal to three times the diameter of the water pipe + 400mm. The side of each pair of adjacent columns 1 that is close to each other is fixedly connected to the end of the lower crossbeam 2. The mounting plate 6 is set within the rectangular area enclosed by the four columns 1. The mounting plate 6 is connected to the top main beam 3, the top secondary beam 4, and the lower crossbeam 2 through the submersible pump moving mechanism 7.

[0028] In this embodiment, during use, the operator fixes the submersible pump to the upper surface of the mounting plate 6 and moves the mounting plate 6 underwater so that the submersible pump can be completely submerged in water to treat sewage. When the submersible pump needs to be repaired, after shutting off the water pipe and releasing the relative fixing between the submersible pump and the water pipe, the submersible pump moving mechanism 7 drives the submersible pump to move upward. When the submersible pump moves above the liquid surface, the operator can then repair the submersible pump.

[0029] As a preferred embodiment, the submersible pump moving mechanism 7 includes a mounting frame 71, a moving bar 72, a pull rope 73, a locking block 75, a spring 76, and a pulling assembly 77. The front and rear sides of the mounting frame 71 near the bottom are fixedly connected to the middle of the side of the two lower transverse beams 2 that are close to each other. The front view of the mounting frame 71 is U-shaped, and the left view of the mounting frame 71 is also U-shaped. The front and rear surfaces of the mounting frame 71 near the top are fixedly connected to the side of the two upper transverse beams 3 that are close to each other. The left and right surfaces of the mounting frame 71 near the top are fixedly connected to the side of the two upper secondary beams 4 that are close to each other. Next, the mounting frame 71 is fixedly connected to the top main beam 3, the top secondary beam 4, and the lower cross beam 2 to ensure stable installation. The inner wall of the mounting frame 71 is provided with a sliding groove 74, and a slider 79 is slidably connected to the inner wall of the sliding groove 74. The slider 79 slides up and down relative to the sliding groove 74. There are two sliders 79. The two sliders 79 are fixedly connected to the left and right sides of the moving strip 72 on the side near the middle of the mounting frame 71. A pull rope 73 runs through the inner wall of the moving strip 72. The pull rope 73 is coated with a waterproof coating. The lower end of the pull rope 73 is fixedly connected to the upper side of the locking block 75. The inner wall of the mounting plate 6 has a sliding groove 710. The outer wall of the locking block 75 is slidably connected to the inner wall of the sliding groove 710. The sliding direction of the locking block 75 relative to the sliding groove 710 is up and down. The upper side of the locking block 75 is elastically connected to the inner wall of the sliding groove 710 by a spring 76. One end of the spring 76 is fixedly connected to the upper side of the locking block 75, and the other end of the spring 76 is fixedly connected to the inner wall of the sliding groove 710. A pulling component 77 is provided at the end of the pull rope 73 away from the locking block 75. The actuating end of the pulling component 77 controls the connection of the pull rope 73. The upper surface of the mounting bracket 71 has a locking mechanism. When the locking block 75 enters the slot 78, the mounting plate 6 cannot move up or down relative to the mounting bracket 71. By pulling the pull rope 73 through the pull assembly 77, the pull rope 73 moves upward. At this time, the pull rope 73 first pulls the locking block 75, causing the locking block 75 to move upward until the spring 76 is compressed to the point where it can no longer be compressed. Then, the pull rope 73 drives the locking block 75 to move backward. When it moves to the point where the rear surface of the mounting plate 6 is in contact with the front surface of the moving bar 72, the pull rope 73 continues to be stressed, and the moving bar 72 and the mounting plate 6 move upward together. Therefore, it can achieve the effect of moving the submersible pump above the liquid surface.

[0030] In a preferred embodiment, the pull assembly 77 includes a mounting frame 771, a rotating wheel 772, a control lever 773, a turntable 774, and a locking lever 775. The inner wall of the mounting frame 771 is rotatably connected to the left and right sides of the rotating wheel 772, and the rear side of the mounting frame 771 is fixedly connected to the wall above the liquid surface. The outer wall of the rotating wheel 772 is fixedly connected to the upper end of the pull rope 73, which is wound around the outer wall of the rotating wheel 772. The inner wall of the rotating wheel 772 passes through and is slidably connected to the outer wall of the control lever 773. The control lever 773 is relative to... The rotating wheel 772 slides left and right. The rotating wheel 772 is coaxially arranged with the control lever 773. The outer wall of the control lever 773 penetrates the inner wall of the mounting frame 771. The left end of the control lever 773 is fixedly connected to the right end of the turntable 774. When the control lever 773 rotates, the turntable 774 rotates synchronously with it. The control lever 773 and the turntable 774 are coaxially arranged. The inner wall of the mounting frame 771 on the left side of the rotating wheel 772 has a mounting groove 777. The turntable 774 is disposed inside the mounting groove 777. The left side is fixedly connected to the right end of the locking lever 775. Multiple locking levers 775 are arranged in a circular array around the axis of the rotating wheel 772. The mounting frame 771 has a positioning groove 776 on the inner wall of the left side of the mounting slot 777. Multiple positioning grooves 776 are arranged in a circular array around the axis of the control lever 773. The number of positioning grooves 776 is a positive integer multiple of the number of locking levers 775. Pulling the control lever 773 to the right causes it to move to the right, thus... The rotating turntable 774 and the locking lever 775 move to the right together, causing the locking lever 775 to leave the positioning groove 776. At this time, the turntable 774 can rotate normally. Then, the control lever 773 is rotated, which drives the rotating wheel 772 to rotate, thus causing the rotating wheel 772 to rotate and reel in the line. After the line is reeled in, the operator pushes the control lever 773 to the left, which causes the control lever 773 to push the turntable 774 to the left, thus pushing the locking lever 775 into the positioning groove 776, thereby achieving the effect of fixing the line reel in.

[0031] As a preferred embodiment, a rope positioning component 8 is provided on the front side of the rear top main beam 3, which is used to position the rope 73.

[0032] As a preferred embodiment, the pull rope positioning assembly 8 includes a frame 81 and a rotating wheel 82. The rear surface of the frame 81 is fixedly connected to the front surface of the rear top main beam 3. The left and right sides of the rotating wheel 82 are rotatably connected to the inner wall of the frame 81. The diameter of the middle part of the rotating wheel 82 is smaller than the diameter of the left and right sides. The pull rope 73 passes through the inner wall of the frame 81, and the outer wall of the pull rope 73 contacts the outer wall of the rotating wheel 82. By rotating the rotating wheel 82, it is ensured that the pull rope 73 is prevented from wearing out after being pulled.

[0033] As a preferred embodiment, the moving strip 72 is connected to the mounting plate 6 via an anti-offset component 9, which ensures that the upper surface of the mounting plate 6 remains horizontal during vertical movement.

[0034] As a preferred embodiment, the anti-deviation component 9 includes a limiting groove 91, a sliding rod 92, and a second spring 93. The limiting groove 91 is located on the rear side of the mounting plate 6, and the inner wall of the limiting groove 91 is slidably connected to the outer wall of the sliding rod 92. Through the relative sliding arrangement, it is ensured that the mounting plate 6 can only slide back and forth relative to the moving bar 72, thereby preventing the mounting plate 6 from deviating. The rear end of the sliding rod 92 is fixedly connected to the front surface of the moving bar 72, and the front end of the sliding rod 92 is elastically connected to the inner wall of the limiting groove 91 through the second spring 93. One end of the second spring 93 is fixedly connected to the front end of the sliding rod 92, and the other end of the second spring 93 is fixedly connected to the inner wall of the limiting groove 91.

[0035] As a preferred embodiment, an auxiliary wheel 1 is rotatably connected to the inner wall of the mounting plate 6.

An auxiliary wheel 2 is rotatably connected to the inner wall of the moving bar 72. The auxiliary wheel 2 is located at the corner of the pull rope 73, and the outer wall of the pull rope 73 contacts the outer wall of the auxiliary wheel 2. By setting the auxiliary wheel 1 and the auxiliary wheel 2, it is ensured that the pull rope 73 can be transferred through the auxiliary wheel 1 or the auxiliary wheel 2 during the movement, thus preventing wear on the pull rope 73.
