Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering sewage extraction, in particular to a construction engineering sewage extraction mechanism. Background Art

[0002] Construction engineering refers to the process of constructing a building from scratch or renovating an existing one through a series of activities, including planning, surveying, designing, constructing, installing, and maintaining various buildings, structures, and their ancillary facilities. This foundation construction process generates a large amount of construction wastewater, such as flushing water and slurry water from concrete pouring. This wastewater contains suspended solids such as cement and sand. If not extracted and treated, it will accumulate in the foundation pit, affecting subsequent construction operations and polluting the soil environment. The use of extraction mechanisms is designed to prevent this.

[0003] In the prior art, some sewage extraction mechanisms usually use a submersible pump, connect the submersible pump connecting block to the suction pipe, and then place the submersible pump into the sewage, so that the sewage is discharged through the suction pipe when the submersible pump is started. The sealing of the pumping work is completed by a sealing ring, and then the sewage is extracted. However, after being exposed to the sewage environment for a long time, the performance of the sealing ring will gradually decrease due to the erosion of acidic or alkaline substances in the sewage, causing sewage to leak from the seal, which will not only reduce the efficiency of sewage extraction, but also cause sewage to leak around the equipment, causing pollution to the working environment. Therefore, in response to the above shortcomings, a sewage extraction mechanism for construction projects is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology and propose a construction project sewage extraction mechanism, which aims to improve the problem in the existing technology that the sealing ring at the connection between the submersible pump connecting pipe and the suction pipe is exposed to the sewage environment for a long time, thereby reducing the performance of the sealing ring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage extraction mechanism for a construction project, comprising a water pump housing, the bottom end of the water pump housing is fixedly connected to a base, the bottom end of the base is fixedly connected to a support assembly for carrying objects, the inner middle end of the water pump housing is fixedly connected to a shaft sleeve, the bottom end of the water pump housing is fixedly connected to a flow assembly for providing power, the bottom end of the water pump housing is provided with a plurality of extraction holes, the top end of the water pump housing is fixedly connected to a connecting block, the interior of the connecting block is provided with a sliding hole, the inner bottom end of the connecting block is fixedly connected to a plurality of telescopic rods, the outer surface of the telescopic rods is provided with a strong spring, the top ends of the plurality of telescopic rods are fixedly connected to a connecting ring, the top end of the connecting ring is fixedly connected to a slip ring, the top end of the slip ring is fixedly connected to a dynamic ring, the top end of the connecting block is internally threadedly connected to a water pump pipe, and the bottom end of the water pump pipe is fixedly connected to a static ring.

[0007] Furthermore, the support assembly includes a plurality of support legs, the top ends of the plurality of support legs are fixedly connected to the bottom ends of the base, and the bottom ends of the support legs are fixedly connected to support seats.

[0008] Furthermore, the flow component includes a motor, the bottom end of the motor is fixedly connected to the bottom end of the water pump housing, the driving end of the motor is fixedly connected to a rotating rod, the outside of the rotating rod is fixedly connected to multiple diffusers, and the inside of the diffuser is fixedly connected to an impeller.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, when the pump pipe is threadedly connected to the connecting pipe, the dynamic ring and the static ring come into contact, which in turn applies force to the powerful spring on one side of the dynamic ring, generating a rebound force. The rebound force of the powerful spring provides additional sealing pressure for the contact between the dynamic and static rings. This pressure can make the sealing surfaces fit more tightly, effectively preventing acidic or alkaline substances in the sewage from corroding the sealing surfaces and preventing sewage from leaking from the seal, thus ensuring the sealing of the sewage extraction process and ensuring that the sewage can be efficiently discharged through the pump pipe without leaking into the surrounding environment of the equipment.

[0015] 2. In the present invention, during the pumping process, the impact of the water will cause the sealing block to drive the baffle to contract the telescopic spring, thereby opening the water outlet hole blocked by the sealing block. After the pumping is completed, the telescopic spring will rebound, causing the sealing block to block the water outlet hole, thereby effectively preventing the pumped sewage from flowing back and ensuring the drainage stability of the sewage pumping system during intermittent operation.

The support assembly is the basic supporting structure of the entire device, and the support assembly includes a plurality of support legs 3, the top ends of the plurality of support legs 3 are fixedly connected to the bottom ends of the base 2, and the bottom ends of the support legs 3 are fixedly connected to a support seat 4, which increases the contact area with the ground or the placement plane, and can make the entire device more stably placed and prevent it from tipping over due to vibration or unbalanced force during operation. The middle end of the inner part of the water pump housing 1 is fixedly connected to a shaft sleeve 5, and the bottom end of the water pump housing 1 is fixedly connected to a flow assembly for providing power, and the flow assembly includes a motor 6, and the bottom end of the motor 6 is fixedly connected to the bottom end of the water pump housing 1 to prevent displacement during operation;

[0025] The driving end of the motor 6 is fixedly connected to a rotating rod 8 to ensure that power can be effectively transmitted to the rotating rod 8 when the motor 6 rotates. The water pump housing 1 provides space and support for the rotating rod 8 to rotate. The rotating rod 8 can rotate freely in this space. The outside of the rotating rod 8 is fixedly connected to a plurality of diffusers 9. The outside of the rotating rod 8 is rotatably connected to the inside of the water pump housing 1. The outside of the plurality of diffusers 9 is rotatably connected to the inside of the middle end of the water pump housing 1. The diffuser 9 maintains a certain gap with the inner wall of the water pump housing 1 during rotation, which can not only ensure smooth rotation but also prevent sewage leakage. The inside of the diffuser 9 is fixedly connected to an impeller 10 to ensure that the impeller 10 can rotate synchronously when the diffuser 9 rotates. A plurality of extraction holes 7 are provided at the bottom end of the water pump housing 1 so that sewage can smoothly enter the inside of the water pump housing 1. The top of the water pump housing 1 is fixedly connected to a connecting block 11.

[0026] Reference Figure 1 、 Figure 2 and Figure 4A sliding hole 12 is opened inside the connecting block 11, and a plurality of telescopic rods 13 are fixedly connected to the inner bottom end of the connecting block 11. A strong spring 14 is provided on the outer side of the telescopic rod 13. The other end of the strong spring 14 is fixedly connected to the inner bottom end of the sliding hole 12 to ensure that the spring does not deviate during the extension and contraction process. The top ends of the plurality of telescopic rods 13 are fixedly connected to a connecting ring 15, which can move up and down in the sliding hole 12 under the drive of the telescopic rod 13. The outer side of the connecting ring 15 is slidably connected to the inner side of the sliding hole 12, one end of the strong spring 14 is fixedly connected to the bottom end of the connecting ring 15, and the top end of the connecting ring 15 is fixedly connected to a slip ring 16, which can slide under the drive of the connecting ring 15, the outer sliding connection of the slip ring 16 is inside the top of the connecting block 11, and the outer diameter of the slip ring 16 is adapted to the aperture inside the top of the connecting block 11 to ensure stability during the sliding process. The top of the slip ring 16 is fixedly connected with a dynamic ring 17, and the top of the connecting block 11 is internally threaded with a water pumping pipe 18. This connection method is convenient for installation and disassembly, and can also ensure a certain connection strength. The bottom end of the water pumping pipe 18 is fixedly connected with a static ring 19, and the top of the dynamic ring 17 contacts the bottom end of the static ring 19. This contact method can effectively prevent sewage leakage under normal circumstances.

[0027] Reference Figure 1 、 Figure 2 and Figure 5 The top of the water pump housing 1 is fixedly connected to a support frame 20, which provides additional support and positioning. The internal sliding connection of the support frame 20 is a sliding rod 21, which can slide freely up and down inside the support frame 20, and there is a certain gap between the sliding rod 21 and the inner wall of the support frame 20, but it can ensure the accuracy of sliding. The outer sleeve of the sliding rod 21 is provided with a telescopic spring 22, which can be extended and retracted when subjected to force. The bottom end of the sliding rod 21 is fixedly connected to a sliding plate 23, and the bottom end of the sliding plate 23 is fixedly connected to an arc pad 24. The outer side of the arc pad 24 contacts the top inner side of the water pump housing 1. Its shape is adapted to the top inner side of the water pump housing 1, and it can effectively transmit force when subjected to sewage impact, and can ensure that the water outlet is sealed under normal circumstances. The top of the sliding rod 21 is fixedly connected to a baffle 25, which can prevent the sliding rod 21 from excessive movement under the action of the telescopic spring 22. The bottom end of the baffle 25 contacts the top of the support frame 20, and this contact method can limit the movement range of the baffle 25.

[0028] Working Principle: When the motor 6 is started, the drive end of the motor 6 rotates the rotating rod 8, which in turn rotates the multiple diffusers 9 fixed to its exterior and the impeller 10 fixed to the interior of the diffuser 9. The rotation of the impeller 10 generates centrifugal force, causing sewage to enter the pump housing 1 through the multiple extraction holes 7 at the bottom of the pump housing 1. As the sewage is transported through the extraction holes 7, the heat generated by the movement of the motor 6 is transferred from the motor 6 to the pump housing 1 and then carried away by the flowing sewage, thus ensuring that the motor 6 operates within a relatively suitable temperature range.

[0029] When the water pumping pipe 18 is threadedly connected to the top of the connecting block 11, the static ring 19 fixed at the bottom of the water pumping pipe 18 will contact the top of the dynamic ring 17, which makes the dynamic ring 17 move downward. The dynamic ring 17 drives the slip ring 16 fixed at the top to slide inside the top of the connecting block 11. The slip ring 16 drives the connecting ring 15 fixed at the bottom to slide downward in the sliding hole 12 inside the connecting block 11. The connecting ring 15 causes the strong spring 14 mounted on the outside thereof to be compressed, and the strong spring 14 generates a rebound force. The rebound force provides additional sealing pressure for the contact between the dynamic ring 17 and the static ring 19, thereby ensuring the sealing effect and preventing sewage leakage.

[0030] During the pumping process, the impact of the sewage will act on the arc pad 24. The arc pad 24 is driven by the impact to move the sliding plate 23 fixed at the bottom upward. The sliding plate 23 drives the fixed sliding rod 21 to slide upward inside the support frame 20. The telescopic spring 22 mounted on the outside of the sliding rod 21 is forced to contract. At this time, the water outlet is opened and the sewage can be discharged through the pumping pipe 18.

[0031] When the pumping is completed, the telescopic spring 22 rebounds, and the telescopic spring 22 drives the sliding rod 21 to move downward, and the sliding rod 21 drives the sliding plate 23 and the arc pad 24 to move downward, so that the arc pad 24 returns to the initial position, sealing the water outlet, effectively preventing the pumped sewage from flowing back, and ensuring the drainage stability of the sewage extraction system during intermittent operation.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
