Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a pumping station that is convenient for internal maintenance and replacement. Background Art

[0002] Currently, sewage treatment pumping stations in rural and countryside areas generally have problems with difficult maintenance. Due to the narrow internal space of the pumping station, the installation and replacement of the filter screen and maintenance platform usually require manual entry into the pumping station for operation, which is not only inefficient but also poses safety hazards. With the increasing demand for rural sewage treatment, higher requirements are put forward for the maintenance convenience and safety of the pumping station. In recent years, some pumping station designs have begun to focus on modularization and quick disassembly, but the problem of internal maintenance convenience has not been completely solved.

[0003] In the prior art, the filter screen and maintenance platform of the pumping station usually adopt fixed installation or bolt connection methods. The filter screen and maintenance platform with fixed installation need to be completely disassembled during maintenance, which is time-consuming and laborious; although the bolt connection method can be disassembled, due to the humid internal environment of the pumping station, the bolts are prone to rust and are difficult to disassemble. In addition, some pumping stations use hoisting equipment to assist in maintenance, but the hoisting equipment has high costs and occupies a large space, and is not suitable for small pumping stations.

[0014] Preferably, a ladder is provided inside the pump station body. A sealing cover is installed on the top of the pump station body through a hinge. A water pump body is provided inside the pump station body. A water pump installation pipe is fixedly installed at the bottom of the water pump body. A water pump fixing frame is fixedly installed inside the pump station body, and the top end of the water pump installation pipe is fixedly installed on the water pump fixing frame. One side of the water pump body is connected with a water outlet pipe through a connecting pipe.

[0015] Preferably, a method for using an internal maintenance and replacement type pump station includes the following steps: S1. Install the pump station body at a designated position, connect the water inlet to an external sewage source. The sewage enters the inside of the filter box through the water inlet. The solid impurities in the sewage can be filtered through the filter box, thereby reflecting the function of the pump station of this device. S2. When performing maintenance and cleaning on the filter box, open the sealing cover, remove the second chain from the second positioning rod, pull the second chain. The second chain pulls the connecting strip to drive the vertical frame to move upward, and the vertical frame drives the filter box to move upward, thereby pulling the filter box out of the inside of the pump station body. S3. When performing maintenance on the water pump body inside the pump station body, remove the bolts on the water pump fixing frame at the top port of the pump station body to release the fixed state of the water pump installation pipe. Disconnect the first chain from the first positioning rod. When pulling the first chain, the inspection platform will be driven to deflect around the connection with the mounting seat. The staff goes down into the pump station body through the ladder to remove and inspect the water pump body. S4. When removing the inspection platform, pull the pull rope. The pull rope drives the pull block to move through the pulley. The pull block drives the pull plate to move inside the mounting frame. The pull plate drives the insertion plate to move, and the insertion plate is disengaged from the inside of the mounting groove to release the fixed state of the mounting seat and the inspection platform. At this time, pull the first chain upward, and the first chain will pull the inspection platform upward, thereby removing the inspection ladder from the inside of the pump station body.

[0016] Working principle: When using this device, the pump station body can be fixedly installed at a designated position. By connecting the water inlet to an external sewage source, the sewage can be introduced into the inside of the filter box. The solid impurities in the sewage can be filtered through the filter box. The filtered sewage enters the inside of the pump station body for further treatment. When removing the filter box, the sealing cover can be opened, the second chain can be disengaged from the second positioning rod, and the second chain can be pulled upward. The second chain can pull the connecting strip, and the connecting strip pulls the vertical frame upward through the fixed block. The vertical frame drives the filter box to move upward. And when the filter box moves upward, the first telescopic spring inside the telescopic rod extends, driving the sealing plate to move downward. The sealing plate seals the butting port, preventing the solid impurities inside from falling into the inside of the pump station body during the upward movement of the filter box. Continuously pulling the filter box upward can remove it from the inside of the pump station body. When the water pump body needs to be removed for maintenance, the bolts on the water pump fixing bracket at the port of the pump station body can be removed, thus releasing the fixed state of the water pump mounting bracket, and further releasing the fixed state of the water pump body. Detach the first chain from the first positioning rod, pull the first chain upward, and the first chain will pull the maintenance platform to deflect around the hinge with the mounting seat, thereby making the channel inside the pump station body accessible. The staff can descend into the interior of the pump station body through the ladder and then remove the water pump body. When the maintenance platform needs to be removed for maintenance, first pull the pull rope. The pull rope drives the pull plate through the pull block, and the pull plate drives the plug board to move, disengaging the plug board from the inside of the mounting groove, thus releasing the fixed state of the mounting seat. Pull the first chain, and the chain will pull the maintenance platform downward. Continuously pulling the first chain can remove the maintenance platform from the pump station body.

[0017] The present invention provides a pump station that is convenient for internal maintenance and replacement, with the following beneficial effects: 1. In the present invention, when the filter box needs to be removed, the second chain can be detached from the second positioning rod, and the second chain is pulled upward. The second chain can then pull the vertical frame upward through the connecting bar. The vertical frame drives the filter box to move upward. While the filter box is moving upward, it can drive the slider to slide inside the chute, thereby increasing the stability and directivity of the lifting of the filter box. Continuously pulling the filter box can remove the filter box from the pump station body, and the removal process is extremely convenient. There is no need for the staff to enter the interior of the pump station, reducing the complexity of disassembling and assembling the filter box.

[0018] 2. In the present invention, when the filter box moves upward, the first telescopic spring inside the telescopic rod can push the inner rod of the telescopic rod downward. At this time, the telescopic rod can extend and push the sealing plate downward, and the sealing plate moving downward can block the butting port. Therefore, when the filter box is removed, the solid impurities inside it can be prevented from falling into the interior of the pump station body, increasing the practicality of the device during use.

[0019] 3. In the present invention, when the water pump body inside the pump station body needs to be removed, first remove the bolts on the water pump fixing bracket at the top port of the pump station body, thereby releasing the fixed state of the water pump installation pipe. At this time, the fixed state of the water pump body can be released. By pulling the first chain upward, the first chain can pull the maintenance platform to rotate around the hinge with the mounting seat. At this time, it is convenient for the staff to enter the interior of the pump station body with the help of the ladder and take out the water pump body. This process greatly reduces the time for the staff to enter the pump station body and does not require the removal of the maintenance platform, greatly increasing the convenience during use.

[0020] 4. In the present invention, when the maintenance platform is to be dismantled and repaired, the pull rope can be pulled first. The pull rope drives the pull block through the pulley, the pull block drives the pull plate, and the pull plate drives the insertion plate to move, so that the insertion plate is disengaged from the inside of the installation groove, and the fixed state of the installation seat and the maintenance platform can be released. At this time, the first chain can be pulled upward, and continuously pulling the chain upward can remove the maintenance platform from the inside of the pump station body, and the dismantling process is extremely convenient, and the staff does not have to enter the inside of the pump station body again.

[0023] Next, in combination with the accompanying drawings of the specification, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figure 1 、attached Figure 2 、attached Figure 4 and attached Figure 8 , the embodiment of the present invention provides a pump station that is convenient for internal maintenance and replacement, including a pump station body 1. Two support frames 5 are fixedly installed inside the pump station body 1. A filter box 4 is provided inside the pump station body 1. A placement rack 19 is fixedly connected between the two support frames 5, and the filter box 4 is arranged on the top of the placement rack 19. Two slide rails 8 are fixedly installed on the top surfaces of the two support frames 5. Two sliders 38 are fixedly connected to both sides of the filter box 4, and the sliders 38 are arranged inside the slide rails 8. A vertical frame 7 is fixedly connected to the top surface of the filter box 4. Two fixing blocks 27 are fixedly connected to the top surface of the vertical frame 7. A connecting bar 28 is fixedly connected between the two fixing blocks 27. A second chain 12 is fixedly connected to the center of the connecting bar 28. An inspection platform 11 is provided at the top of the two support frames 5. One side of the inspection platform 11 is hinged to a mounting seat 20. A mounting frame 6 is fixedly installed on one side of one of the two support frames 5. A disassembly and assembly component is provided inside the mounting frame 6. A first chain 10 is fixedly connected to the center of the top surface of the inspection platform 11.

[0025] Specifically, the slider 38 is arranged inside the slide rail 8, and the slider 38 is slidably connected to the slide rail 8. A plurality of filter holes are formed on the surface of the filter box 4, which can filter the sewage entering the inside of the filter box 4, so that the solid impurities remain inside the filter box 4. The material used for the filter box 4 of this device is 316 stainless steel, which has the characteristics of strong corrosion resistance, can effectively resist the corrosion of sewage and some corrosive substances, and enhances the service life of the filter box 4. The bottom end of the second chain 12 is fixedly connected to the center of the connecting bar 28. Therefore, when the second chain 12 is vertically pulled, the second chain 12 can drive the connecting bar 28 to move. The connecting bar 28 pulls the vertical frame 7 to move upward through the fixing block 27, and the vertical frame 7 pulls the filter box 4 to move upward. By continuously pulling the second chain 12, the filter box 4 can be pulled out from the inside of the pump station body 1, so as to facilitate the removal of the filter box 4 from the inside of the pump station body 1, and it is no longer necessary for the staff to enter the inside of the pump station body 1 during the removal process. Since there are often a large amount of toxic gases and a large number of odor molecules inside the pump station body 1, the method of removing the filter box 4 of this device greatly increases the practicality during use. And when the filter box 4 is removed, the slider 38 can slide inside the chute, which can ensure the stability and directivity of the filter box 4 when it moves upward.

[0026] Please refer to the attached Figure 10 , the disassembly and assembly component includes a pull plate 37, a plug plate 35, a pull block 36 and a pull rope 22. The pull plate 37 is arranged inside the mounting frame 6, the plug plate 35 is fixedly installed on one side surface of the pull plate 37, the pull block 36 is fixedly installed at the center of the other side surface of the pull plate 37, and one end of the pull rope 22 is fixedly connected to the pull block 36.

[0027] Specifically, the pull plate 37 is movably installed inside the mounting frame 6, and the surface of the pull plate 37 is attached to the surface of the support frame 5. The plug plate 35 extends into the inside of the support frame 5. A notch is provided on one side surface of the support frame 5, and the plug plate 35 is inserted into the notch. When the pull rope 22 is pulled, the pull rope 22 can pull the pull plate 37 to move inside the mounting frame 6 through the pull block 36. When the pull plate 37 moves, the plug plate 35 can be driven to move.

[0028] Please refer to the attached Figure 9 and the attached Figure 10 , a pulley 21 is fixedly installed on the outer surface of the mounting frame 6 through a fixing frame, and the pull rope 22 is wound around the outer surface of the pulley 21. An installation groove 33 is provided on one side of the mounting seat 20. Second telescopic springs 34 are symmetrically arranged inside the mounting frame 6, and one end of each second telescopic spring 34 is fixedly connected to one side surface of the pull plate 37.

[0029] Specifically, the size and dimensions of the plug plate 35 correspond to those of the installation groove 33. When the plug plate 35 is inserted into the installation groove 33, the mounting seat 20 can be fixedly installed on the support frame 5, thereby fixing the position of the maintenance platform 11. Through the pulley 21, the pulling direction of the pull rope 22 can be restricted. Then, when the pull rope 22 is pulled, the pull rope 22 can stably pull the pull block 36 to move. And when the pull rope 22 pulls the pull block 36 to move and drives the pull plate 37 to move, the pull plate 37 can squeeze the second telescopic spring 34 inward. At the same time, the second telescopic spring 34 can push the pull plate 37 through the reaction force, thereby ensuring the initial position of the pull plate 37 and the plug plate 35, enhancing the stability of the mounting seat 20 installed on the support frame 5, and indirectly increasing the stability of the installation of the maintenance platform 11.

[0030] Please refer to the attached Figure 4 and the attached Figure 9 , a first positioning rod 23 is fixedly installed on the inner wall of the pump station body 1, and the first chain 10 is sleeved on the outer side of the first positioning rod 23. A second positioning rod 26 is fixedly installed on the inner wall of the pump station body 1, and the second chain 12 is sleeved on the outer side of the second positioning rod 26.

[0031] When the first chain 10 and the second chain 12 are not in use, the pull rings at the tops of the first chain 10 and the second chain 12 can be respectively sleeved on the outer sides of the first positioning rod 23 and the second positioning rod 26, thereby preventing the first chain 10 and the second chain 12 from falling off to the bottom of the pump station body 1. Moreover, rubber sleeves are sleeved on the outer surfaces of the first positioning rod 23 and the second positioning rod 26. Due to the plastic property of the rubber sleeves, when the first chain 10 and the second chain 12 are sleeved on their outer sides, the rubber sleeves can expand outwards, and then the outer surfaces thereof are closely attached to the inner walls of the chain end pull rings, thereby preventing the first chain 10 and the second chain 12 from falling off the first positioning rod 23 and the second positioning rod 26.

[0032] Please refer to the attached Figure 1 and the attached Figure 4 , an interface 25 is opened on one side of the filter box 4, and a water inlet 2 is communicated with the outer surface of the pump station body 1, and the water inlet 2 is communicated with the interface 25.

[0033] Specifically, when the filter box 4 is installed inside the pump station body 1 and placed on the top of the placement rack 19, the position of the interface 25 can be made to face the water inlet 2 directly, so that the sewage entering the water inlet 2 can directly enter the inside of the filter box 4.

[0034] Please refer to the attached Figure 4 、the attached Figure 6 and the attached Figure 7 , a sealing plate 24 is movably installed inside the filter box 4. Two first abutting blocks 29 are fixedly connected to one side of the sealing plate 24, and two second abutting blocks 31 are fixedly connected to the top surface of the water inlet 2, and the first abutting block 29 is in contact with the second abutting block 31.

[0035] Specifically, the sealing plate 24 is movably installed inside the filter box 4, and the position of the first abutting block 29 is directly opposite to that of the second abutting block 31. Since the slider 38 still slides inside the slide rail 8 when the filter box 4 moves downwards, the positions of the first abutting block 29 and the second abutting block 31 can be ensured to be always relative. When the filter box 4 moves downwards, the second abutting block 31 can upwards abut against the first abutting block 29, and the first abutting block 29 moves upwards, which can drive the sealing plate 24 to move upwards, thereby enabling the interface 25 to be docked and communicated with the water inlet 2.

[0036] Please refer to the attached Figure 5 , a plurality of telescopic rods 30 are fixedly connected to the bottom surface of the vertical frame 7, and the bottom ends of the telescopic rods 30 are fixedly connected to the sealing plate 24. A first telescopic spring 32 is arranged inside the telescopic rods 30.

[0037] Specifically, the telescopic rod 30 is divided into an inner rod and an outer rod, and both ends of the first telescopic spring 32 are respectively connected to the inner rod and the outer rod. When the filter box 4 moves upward, the first abutting block 29 and the second abutting block 31 are not affected by the gravity of the filter box 4, and thus the first abutting block 29 and the second abutting block 31 can be separated. At this time, the first telescopic spring 32 inside the telescopic rod 30 can drive the telescopic rod 30 to extend, and the telescopic rod 30 pushes the sealing plate 24 downward. When the sealing plate 24 moves downward, it can block the docking port 25, preventing the solid impurities inside the filter box 4 from falling into the inside of the pump station body 1 through the docking port 25 when the filter box 4 is removed by moving upward.

[0038] Please refer to the appendix Figure 8 , a plurality of fixing rods 17 are fixedly installed on the inner wall of the pump station body 1, and the fixing rods 17 are fixedly connected to the slide rail 8. Strengthening ribs 18 are symmetrically installed on the bottom surfaces of the two support frames 5, and one end of the strengthening ribs 18 is fixedly connected to the inner wall of the pump station body 1.

[0039] Specifically, through the plurality of fixing rods 17, the position of the slide rail 8 can be fixedly supported, increasing the stability of the slide rail 8 installed inside the pump station body 1. The strengthening ribs 18 are arranged obliquely, and thus can form an oblique support for the support frame 5, ensuring the stability of the support frame 5 installed inside the pump station body 1.

[0040] Please refer to the appendix Figure 1 , appendix Figure 2 and appendix Figure 3 , a ladder 9 is provided inside the pump station body 1. The top of the pump station body 1 is installed with a sealing cover 3 through a hinge. A water pump body 13 is provided inside the pump station body 1. A water pump installation pipe 14 is fixedly installed at the bottom of the water pump body 13. A water pump fixing frame 15 is fixedly installed inside the pump station body 1, and the top end of the water pump installation pipe 14 is fixedly installed on the water pump fixing frame 15.

[0041] Specifically, the ladder 9 is fixedly installed inside the pump station body 1. Through the ladder 9, the staff can conveniently enter the inside of the pump station body 1. When overhauling the water pump body 13, the user can pull the first chain 10, and the first chain 10 pulls the overhaul platform 11 to rotate around the hinge point with the mounting seat 20, so that the internal passage of the pump station body 1 can be communicated. At the same time, remove the bolts on the water pump fixing bracket 15 at the top port of the pump station body 1, and the fixing state of the water pump installation pipe 14 can be released. At this time, the fixing state of the water pump body 13 can be released. At this time, the staff can go down into the pump station body 1 through the ladder 9 to remove the water pump body 13. And during the whole removal process, there is no need to remove the overhaul platform 11 anymore, which greatly shortens the time to enter the pump station body 1. And when removing and maintaining the overhaul platform 11, the pull rope 22 can be pulled first. The pull rope 22 drives the pull plate 37 to move through the pull block 36, and the pull plate 37 drives the plug plate 35 to move, so that the plug plate 35 is separated from the inside of the installation groove 33, and the fixing state of the mounting seat 20 and the overhaul platform 11 can be released. At this time, the first chain 10 can be pulled upward, and the first chain 10 pulls the overhaul platform 11 to move upward, so that the overhaul platform 11 can be removed from the inside of the pump station body 1, and the removal process is extremely simple.

[0042] Please refer to the attached Figure 1 - attached Figure 10 , which is convenient for the use method of the internal maintenance and replacement type pump station, including the following steps: S1. Install the pump station body 1 at the designated position, connect the water inlet 2 with the external sewage source, and the sewage enters the inside of the filter box 4 through the water inlet 2. The solid impurities in the sewage can be filtered through the filter box 4, so as to reflect the function of the pump station of this device; S2. When overhauling and cleaning the filter box 4, open the sealing cover 3, remove the second chain 12 from the second positioning rod 26, pull the second chain 12, and the second chain 12 drives the vertical frame 7 to move upward through the connecting strip 28. The vertical frame 7 drives the filter box 4 to move upward, and then pulls the filter box 4 out of the pump station body 1; S3. When overhauling the water pump body 13 in the pump station body 1, remove the bolts on the water pump fixing bracket 15 at the top port of the pump station body 1, release the fixing state of the water pump installation pipe 14, detach the first chain 10 from the first positioning rod 23, and pull the first chain 10. When the first chain 10 is pulled, it will drive the overhaul platform 11 to deflect around the connection with the mounting seat 20. The staff goes down into the pump station body 1 through the ladder 9 to remove and overhaul the water pump body 13. S4. When the maintenance platform 11 is to be removed, pull the pull rope 22. The pull rope 22 passes through the pulley 21; pull the pull block 36 to move. The pull block 36 drives the pull plate 37 to move inside the installation frame 6.
