Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a drainage device for water conservancy engineering. Background Technology

[0002] In water conservancy projects, a sump well is a facility that collects rainwater or groundwater in a well for distribution to sewage or stormwater pipes. Sump wells typically have a large diameter and are located along roadsides or sidewalks. They effectively collect rainwater, preventing backflow and drainage into sewers, and also collect groundwater seeping from the soil. In construction and underground engineering, sump wells drain groundwater, lowering the water table and ensuring the stability and safety of the project. Furthermore, there are different types of sump wells, such as rainwater sump wells, sewage sump wells, ventilation wells, and inspection wells. Each type has different characteristics and functions. Currently, many sump wells are equipped with sewage pumps for drainage.

[0003] Traditional sewage pump devices for sump pits still have some shortcomings in use: the sewage pumps used in sump pits are generally used in conjunction with sewage pump couplers, so that workers above the pit can lift the sewage pump for maintenance and dredging at any time by means of ropes. However, when using traditional sewage pump couplers, only a limiting mechanism is set at the top, which makes it easy for the bottom part of the coupler gasket that contacts the bend to be blown open under high water pressure, resulting in serious leakage.

[0004] In addition, the sewage pump inlet is directly exposed to the outside, and some collection wells contain a lot of garbage and other debris, which makes the sewage pump prone to clogging, resulting in excessive cleaning frequency for staff and causing considerable inconvenience.

[0005] Therefore, it is necessary to provide a new drainage device for water conservancy projects to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a drainage device for water conservancy projects that can reduce the blockage of sewage pump inlet and prevent the bottom of the sewage pump coupler from being easily washed away.

[0007] To solve the above-mentioned technical problems, the present invention provides a drainage device for water conservancy projects, comprising: a base, a limiting component, and a protective component. A sewage pump is installed on one side of the base. The protective component includes a cover, two of which are located outside the sewage pump and are symmetrically arranged on the left and right sides. Ear plates are fixedly connected to the surface of the cover, and a filter screen is fixedly connected to the bottom of the cover. The filter screen is located below the sewage pump. Mounting grooves are provided on the front and rear side walls of the base. Electric telescopic rods are fixedly connected inside the mounting grooves, and scrapers are fixedly connected between the output ends of the two electric telescopic rods.

[0008] A bent pipe is fixedly connected to the top of the base. A connecting plate is fixedly connected to the output end of the sewage pump by bolts. The limiting assembly includes a top plate, which is fixedly connected to the top of the connecting plate. Limiting sleeves are fixedly connected to the front and rear edges of the surface of the top plate. Limiting posts are fixedly connected to the front and rear edges of the top of the bent pipe. The limiting posts and limiting sleeves are matched. Limiting blocks are symmetrically fixedly connected to the front and rear sides of the side wall of the base facing the sewage pump. The limiting blocks have slots. Locking blocks are fixedly connected to the front and rear edges of the bottom of the connecting plate. The locking blocks and locking slots are matched.

[0009] As a further embodiment of this utility model, a protective shell is fixedly connected to the base surface located outside the mounting groove, and the telescopic end of the electric telescopic rod penetrates the surface of the protective shell.

[0010] Through the above technical solution, in order to prevent large garbage and other impurities from clogging the sewage pump inlet in some collection wells, and to reduce the frequency of manual cleaning of the sewage pump by workers, a cover is added to the inlet end of the sewage pump. The cover is divided into two parts and is fixed together by bolts and nuts on the ear plate. When the sewage pump is working, larger impurities will be intercepted by the filter screen at the bottom. In addition, to prevent impurities from staying under the filter screen, the structure is also equipped with a scraper driven by an electric telescopic rod on the base to clean the bottom of the filter screen. This structural design can extend the time for the sewage pump to operate stably and normally inside the collection well, and the design is user-friendly.

[0011] As a further embodiment of this utility model, two adjacent ear plates are fixedly connected by bolts and nuts, and the top height of the scraper is flush with the bottom height of the filter screen.

[0012] With the above technical solution, when there are some large impurities at the bottom of the filter screen that affect the operation of the sewage pump, the electric telescopic rod can be activated to drive the scraper to move laterally and push away these impurities.

[0013] As a further embodiment of this utility model, a gasket is fixedly connected to the side wall surface of the connecting piece facing the bend, and the gasket is in contact with the surface of the bend.

[0014] With the above technical solution, most sewage pumps on the market use the gasket on the connecting plate to abut against the outer surface of the inlet of the curved pipe on one side. This connection method makes it convenient for the staff above not to go down into the collection well to take out the sewage pump, but to directly pull it up with the hoisting rope fixed to the sewage pump.

[0015] As a further embodiment of this utility model, sliding sleeves are fixedly connected to both the front and rear side walls of the top plate, and guide rods are fixedly connected to both the front and rear sides of the outer surface of the bent pipe, with the sliding sleeves slidably connected to the guide rods on one side.

[0016] By using the above technical solution, a guide rod is installed to facilitate workers in lowering the hoisting rope to stably transport the sewage pump to the designated position on one side of the bend.

[0017] As a further embodiment of this utility model, a fixed water pipe is fixedly connected to the end of the bend away from the sewage pump, the top of the guide rod is fixedly connected to the fixed water pipe through a connecting block, and a hanging rope is fixedly connected to the top of the sewage pump.

[0018] The above technical solution allows for easy lifting of the sewage pump by workers using a hoisting rope, while the fixed water pipe can be connected to external pipelines to drain the sewage from the collection well.

[0019] As a further embodiment of this utility model, the two said card blocks respectively pass through the card slot on one side, and the two said limiting posts respectively pass through the limiting sleeve on one side.

[0020] With the above technical solution, when the user lowers the hoisting rope, the sliding sleeve located on the outside of the guide rod moves downward stably. At this time, the positioning pin on the bend inserts into the limiting sleeve on the top plate to limit the top of the connecting piece, while the bottom locking block inserts into the locking groove of the base to achieve bottom limiting of the connecting piece. In this way, when the sewage pump is working, even if there is high water pressure in the bend, the gasket on the connecting piece is not easily blown open with a large gap, causing serious leakage. The structural design is reasonable.

[0021] Compared with related technologies, the drainage device for water conservancy projects provided by this utility model has the following beneficial effects:

[0022] 1. In this utility model, in order to prevent large garbage and other impurities from being present in some collection wells, which could lead to blockage at the inlet of the sewage pump, and to reduce the frequency of manual cleaning of the sewage pump by the staff, a cover is added to the inlet end of the sewage pump. The cover is divided into two parts and is fixed together by bolts and nuts on the ear plate. When the sewage pump is working, larger impurities will be intercepted by the filter screen at the bottom. In addition, to prevent impurities from staying on the bottom of the filter screen, the structure is also equipped with a scraper driven by an electric telescopic rod on the base to clean the bottom of the filter screen. This structural design can extend the time for the sewage pump to operate stably and normally inside the collection well, and the design is user-friendly.

[0023] 2. In this utility model, when the user lowers the hoisting rope, the sliding sleeve located outside the guide rod moves downward stably. At this time, the positioning pin on the bend is inserted into the limiting sleeve on the top plate to limit the top of the connecting piece, while the bottom locking block is inserted into the locking groove of the base to achieve bottom limiting of the connecting piece. In this way, when the sewage pump is working, even if there is high water pressure in the bend, the gasket on the connecting piece is not easily blown open with a large gap, causing serious leakage. The structural design is reasonable. Attached Figure Description

[0031] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a drainage device for water conservancy projects according to this utility model; Figure 2 This is a partial structural schematic diagram of a drainage device for water conservancy engineering according to the present invention; Figure 3 This is a partial structural breakdown diagram of a drainage device for water conservancy engineering according to the present invention. Figure 1 ; Figure 4 This is a partial structural breakdown diagram of a drainage device for water conservancy engineering according to the present invention. Figure 2 A drainage device for a water conservancy project includes:

[0032] The base 1, the limiting component 6, and the protective component 7 are provided. A sewage pump 5 is provided on one side of the base 1. The protective component 7 includes a cover 10. Two covers 10 are located outside the sewage pump 5 and are arranged symmetrically on the left and right. Ear plates 11 are fixedly connected to the surface of the cover 10. A filter screen 21 is fixedly connected to the bottom of the cover 10. The filter screen 21 is located below the sewage pump 5. The front and rear side walls of the base 1 are provided with mounting grooves. Electric telescopic rods 17 are fixedly connected inside the mounting grooves. A scraper 9 is fixedly connected between the output ends of the two electric telescopic rods 17.

[0033] A bend 2 is fixedly connected to the top of the base 1. A connecting piece 12 is fixedly connected to the output end of the sewage pump 5 by bolts. The limiting assembly 6 includes a top plate 19, which is fixedly connected to the top of the connecting piece 12. Limiting sleeves 13 are fixedly connected to the front and rear edges of the surface of the top plate 19. Limiting posts 14 are fixedly connected to the front and rear edges of the top of the bend 2. The limiting posts 14 and the limiting sleeves 13 are matched. Limiting blocks 15 are symmetrically fixedly connected to the front and rear of the side wall surface of the base 1 facing the sewage pump 5. A slot 16 is opened in the limiting block 15. A locking block 22 is fixedly connected to the front and rear edges of the bottom of the connecting piece 12. The locking block 22 and the slot 16 are matched.

[0034] like Figure 1-4 As shown, a protective housing 8 is fixedly connected to the surface of the base 1 located outside the mounting groove, and the telescopic end of the electric telescopic rod 17 penetrates the surface of the protective housing 8.

[0035] To prevent large debris and other impurities from clogging the inlet of the sewage pump 5 in some collection wells, and to reduce the frequency of manual cleaning of the sewage pump 5, a cover 10 is added to the inlet end of the sewage pump 5. The cover 10 is divided into two parts, which are fixed together by bolts and nuts on the ear plate 11. When the sewage pump 5 is working, larger impurities will be intercepted by the filter screen 21 at its bottom. In addition, to prevent impurities from staying under the filter screen 21, a scraper 9 driven by an electric telescopic rod 17 is also set on the base 1 to clean the bottom of the filter screen 21. This structural design can extend the time that the sewage pump 5 can operate stably and normally inside the collection well, and the design is user-friendly.

[0036] like Figure 1-4 As shown, two adjacent ear plates 11 are fixedly connected by bolts and nuts, and the top height of the scraper 9 is flush with the bottom height of the filter screen 21.

[0037] When there are some large impurities at the bottom of the filter screen 21 that affect the operation of the sewage pump 5, the electric telescopic rod 17 can be activated to drive the scraper 9 to move laterally and push away these impurities.

[0038] like Figure 1-4 As shown, a gasket 20 is fixedly connected to the side wall surface of the connecting piece 12 facing the bend 2, and the gasket 20 is in contact with the surface of the bend 2.

[0039] Currently, most common sewage pumps 5 on the market use the gasket 20 on the connecting plate 12 to abut against the outer surface of the inlet of the bend 2 on one side. This connection method makes it convenient for the staff above not to go down into the collection well to take out the sewage pump 5, but to directly pull it up with the hoisting rope fixed to the sewage pump 5.

[0040] like Figure 1-4 As shown, sliding sleeves 18 are fixedly connected to both the front and rear side walls of the top plate 19, and guide rods 4 are fixedly connected to both the front and rear sides of the outer surface of the bend 2. The sliding sleeves 18 are slidably connected to the guide rods 4 on one side.

[0041] Guide rod 4 is installed to facilitate the lowering of the hoisting rope to stably transport the sewage pump 5 to the designated position on one side of the bend 2.

[0042] like Figure 1-4 As shown, a fixed water pipe 3 is fixedly connected to the end of the bend 2 away from the sewage pump 5, the top of the guide rod 4 is fixedly connected to the fixed water pipe 3 through a connecting block, and a hanging rope is fixedly connected to the top of the sewage pump 5.

[0043] The installation of a hoisting rope facilitates the lifting of the sewage pump 5 by staff, while the fixed water pipe 3 can be connected to external pipes to drain the sewage from the collection well.

[0044] like Figure 1-4As shown, two locking blocks 22 pass through the locking slot 16 on one side, and two limiting posts 14 pass through the limiting sleeve 13 on one side.

[0045] When the user lowers the hoisting rope, the sliding sleeve 18 located outside the guide rod 4 moves downward stably. At this time, the positioning pin on the bend 2 is inserted into the limiting sleeve 13 on the top plate 19 to limit the top of the connecting piece 12, while the bottom locking block 22 is inserted into the locking groove 16 of the base 1, thereby limiting the bottom of the connecting piece 12. In this way, when the sewage pump 5 is working, even if there is a high water pressure in the bend 2, the gasket 20 on the connecting piece 12 is not easily blown open with a large gap, causing serious leakage. The structural design is reasonable.

[0046] The working principle of the drainage device for water conservancy projects provided by this utility model is as follows:

[0047] First step: In order to prevent large garbage and other impurities from clogging the inlet of sewage pump 5 in some collection wells, and to reduce the frequency of manual cleaning of sewage pump 5 by staff, a cover 10 is added to the inlet end of sewage pump 5. The cover 10 is divided into two parts and is fixed together by bolts and nuts on the ear plate 11. When sewage pump 5 is working, larger impurities will be intercepted by the filter screen 21 at the bottom. In order to prevent impurities from staying on the underside of filter screen 21, the structure also has a scraper 9 driven by electric telescopic rod 17 on the base 1 to clean the bottom of filter screen 21. This structural design can extend the stable and normal operation time of sewage pump 5 inside the collection well, which is a humanized design.

[0048] The second step: When the user lowers the hoisting rope, the sliding sleeve 18 located outside the guide rod 4 moves downward stably. At this time, the positioning pin on the bend 2 is inserted into the limiting sleeve 13 on the top plate 19 to limit the top of the connecting piece 12, while the bottom locking block 22 is inserted into the locking groove 16 of the base 1, thereby limiting the bottom of the connecting piece 12. In this way, when the sewage pump 5 is working, even if there is a high water pressure in the bend 2, the gasket 20 on the connecting piece 12 is not easily blown open with a large gap, causing serious leakage. The structural design is reasonable.

[0049] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.

[0050] All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.
