Description

Technical Field

[0001] This application belongs to the field of drainage pump technology, specifically a drainage pump for construction. Background Technology

[0002] A drainage pump is a device used to drain accumulated water or sewage from a specific area. It is widely used in construction sites, basements, sewage treatment plants, and other similar locations. It uses an electric motor to drive an impeller, generating pressure to pump water or sewage from a lower location to a higher one or discharge it to a designated location. Drainage pumps can be classified into centrifugal pumps and submersible pumps based on their working principle, and they offer advantages such as high efficiency, durability, and ease of operation.

[0003] For example, application CN219754868U discloses a drainage pump for water conservancy construction that is easy to position quickly. It includes a truck bed and a pump body. Fixed cylinders are fixedly installed at each of the four corners of the truck bed. A detachable support rod is slidably installed inside each fixed cylinder. A fixed block is fixedly connected to the upper end of the truck bed near the fixed cylinder. A fixing pin passes through the fixed block and a through hole. The lower end of the limiting pin is detachably inserted into the fixing pin. An external spiral thread is provided on the outer periphery of the support rod at the lower side of the fixed cylinder. A sleeve is threaded onto the outer periphery of the support rod near the lower side through the external spiral thread. This drainage pump for water conservancy construction, which is easy to position quickly, ensures that the pump body is in a horizontal working state on uneven, muddy ground, avoiding the inconvenience of installation due to site limitations. Furthermore, it eliminates the need for on-site installation and fixing of the pump body, making it very convenient and greatly improving work efficiency.

[0004] However, in this application, there is no buffer structure at the connection end of the drainage pump. During mechanical operation, the connection section is prone to shaking due to vibration, resulting in unstable sealing and easy reduction of mechanical efficiency. Utility Model Content

[0005] The purpose of this application is to provide a drainage pump for construction, in order to solve the problem mentioned above that the connection end of the drainage pump does not have a buffer structure, and the connection section is prone to shaking due to vibration during mechanical operation, resulting in unstable sealing and easy reduction of mechanical efficiency.

[0006] The technical solution adopted in this application is as follows: a drainage pump for construction includes a working platform, a slot welded to one upper surface of the working platform, a limit frame welded to the upper surface of the slot, a U-shaped piece movably connected to the inner surface of the slot, a fixing screw movably connected to the upper surface of the limit frame, a placement platform welded to the upper surface of the working platform next to the slot, and a side baffle welded to the side surface of the placement platform.

[0007] By adopting the above technical solution, the connecting pipe is fixed by inserting a U-shaped piece and adjusting the displacement at the slot to the corresponding fixed radius size. The fixing screw is rotated and pressed down to squeeze the U-shaped piece to complete the pipe fixation. When the connecting pipe is made of soft material, it is then connected to the output end by being coiled on the placement platform to complete the overall fixation. The overall system ensures the buffering of the input and output ends, thereby ensuring that the interface of the connecting pipe is buffered when the motor vibrates, avoiding insufficient sealing and efficiency reduction.

[0008] In a preferred embodiment, a motor is fixedly connected to the upper surface of the work platform, and a pump body is provided on the outer surface of the motor output end.

[0009] By adopting the above technical solution, the motor provides mechanical power for the water pump to pump water. The pump body generates airflow through the output of the motor, which generates negative pressure to draw water in from the input end and discharges it at the output end.

[0010] In a preferred embodiment, an output terminal is provided on the outer surface of the pump body, and an input terminal is provided on the outer surface of the pump body.

[0011] By adopting the above technical solution, the blades inside the pump body rotate, and the internal negative pressure generates water at the input end and discharges it at the output end.

[0012] In a preferred embodiment, a telescopic tube is fixedly connected to the outer surface of the input end, and a support plate is fixedly connected to the outer surface of the telescopic tube at the end away from the input end.

[0013] By adopting the above technical solution, the telescopic tube can easily expand and contract through deformation, and the support plate can easily support and fix the other end.

[0014] In a preferred embodiment, a support crossbar is welded to the outer surface of the support plate, and a support plate is welded to the upper surface of the work platform. The outer surface of the support crossbar is movably inserted into the support plate.

[0015] By adopting the above technical solution, the support crossbar is fixed at the support plate, ensuring the overall stability of the telescopic pipe and support plate, ensuring the sealing of the input and output ends, and ensuring the mechanical effect of the water pump.

[0016] In a preferred embodiment, a support side plate is movably connected to one outer surface of the work platform, and rollers are movably connected to the outer surface of the support side plate.

[0017] By adopting the above technical solution, the rollers facilitate the displacement of the equipment, and the support side plate facilitates the support on that side, ensuring the stability of the water pump during operation.

[0018] In a preferred embodiment, a fixing plate is welded to the outer surface of the support plate, and a threaded rod is movably connected to the outer surface of the support side plate corresponding to the fixing plate.

[0019] By adopting the above technical solution, the threaded rod rotates and rises to abut against the fixed plate for fixation. Thus, when the motor vibrates during operation, the input end is buffered by the telescopic tube, while the support plate stabilizes at this position for output.

[0020] In a preferred embodiment, an adjustment base is provided on the outer surface of the support side plate, and damping support rods are provided on the outer surfaces of the working platform on both sides away from the support side plate.

[0021] By adopting the above technical solution, the height of the base can be adjusted by using nuts to facilitate support on one side, while the damping support rod provides support on the other side.

[0022] In a preferred embodiment, the outer surface of the work platform is provided with handrails, and the lower surface of the work platform is provided with tracks.

[0023] By adopting the above technical solutions, the handrail facilitates the equipment to bear force and perform traction displacement, while the track facilitates the displacement of the equipment.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0025] In this application, the connecting pipe is fixed by inserting a U-shaped piece and adjusting the displacement at the slot to the corresponding fixed radius size. The fixing screw is rotated and pressed down to squeeze the U-shaped piece to complete the pipe fixing. When the connecting pipe is made of soft material, it is then connected to the output end by being coiled on the placement platform to complete the overall fixing. The overall design ensures the buffering of the input and output ends, thereby ensuring that the interface of the connecting pipe is buffered when the motor vibrates, avoiding insufficient sealing and efficiency reduction.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Example:

[0033] Reference Figure 1-4 A drainage pump for construction includes a working platform 1. A slot 2 is welded to the upper surface of one side of the working platform 1. A limit frame 3 is welded to the upper surface of the slot 2. A U-shaped piece 4 is movably connected to the inner surface of the slot 2. A fixing screw 5 is movably connected to the upper surface of the limit frame 3. A placement platform 6 is welded to the upper surface of the working platform 1 next to the slot 2. A side baffle 7 is welded to the side surface of the placement platform 6.

[0034] The connecting pipe is fixed by inserting a U-shaped piece 4 and adjusting the displacement at the slot 2 to the corresponding fixed radius size. The fixing screw 5 is rotated and pressed down to squeeze the U-shaped piece 4 to complete the pipe fixation. When the connecting pipe is made of soft material, it is then connected to the output end 10 by being placed on the placement platform 6 to complete the overall fixation. The overall system ensures the buffering of the input and output ends 10, thereby ensuring that the interface of the connecting pipe is buffered when the motor vibrates, avoiding insufficient sealing and efficiency reduction.

[0035] Reference Figure 1-4 A motor 8 is fixedly connected to the upper surface of the work platform 1, and a pump body 9 is provided on the outer surface of the output end of the motor 8.

[0036] The motor 8 provides mechanical power for the water pump to pump water. The pump body 9 generates airflow through the output of the motor 8, and generates negative pressure to draw water in from the input end 11, and discharges it at the output end 10.

[0037] Reference Figure 1-4 The pump body 9 has an output end 10 on its outer surface and an input end 11 on its outer surface.

[0038] The internal blades of the pump body 9 rotate, and the internal negative pressure generates water suction at the input end 11, which is then discharged at the output end 10.

[0039] Reference Figure 1-4 A telescopic tube 12 is fixedly connected to the outer surface of the input end 11, and a support plate 13 is fixedly connected to the outer surface of the telescopic tube 12 away from the input end 11.

[0040] The telescopic tube 12 can be extended or retracted easily through deformation, and the support plate 13 can be used to support and fix the other end.

[0041] Reference Figure 1-4 The outer surface of the support plate 13 is welded with a support crossbar 14, and the upper surface of the work platform 1 is welded with a support plate 16. The outer surface of the support crossbar 14 is movably inserted into the support plate 16.

[0042] The support crossbar 14 is fixed at the support plate 16 to ensure the overall stability of the telescopic pipe 12 and the support plate 13, to ensure the sealing of the input end 11 and the output end, and to ensure the mechanical effect of the water pump.

[0043] Reference Figure 1-4 The outer surface of the work platform 1 is movably connected to a support side plate 17, and the outer surface of the support side plate 17 is movably connected to a roller 18.

[0044] The rollers 18 facilitate the movement of the equipment, and the support side plate 17 facilitates support on that side, ensuring the stability of the water pump during operation.

[0045] Reference Figure 1-4 A fixing plate 15 is welded to the outer surface of the support plate 13, and a threaded rod 19 is movably connected to the outer surface of the support side plate 17 corresponding to the fixing plate 15.

[0046] The threaded rod 19 rotates and rises to abut against the fixed plate 15 for fixation. Thus, when the motor 8 vibrates during operation, the input end 11 is buffered by the telescopic tube 12, while the support plate 13 stabilizes at this position to output.

[0047] Reference Figure 1-4 An adjustment base 20 is provided on the outer surface of the support side plate 17, and damping support rods 21 are provided on the outer surfaces of the working platform 1 on both sides away from the support side plate 17.

[0048] Adjusting the height of the base 20 with nuts facilitates support on that side, while the damping support rod 21 provides support on the other side.

[0049] Reference Figure 1-4 The outer surface of the work platform 1 is provided with a handrail 22, and the lower surface of the work platform 1 is provided with a track 23.

[0050] Handrail 22 facilitates the equipment to bear force and perform traction displacement, and track 23 facilitates the displacement of the equipment.

[0051] The implementation principle of an embodiment of a drainage pump for construction in this application is as follows:

[0052] The height of the base 20 is adjusted by nuts. After the damping support rod 21 is folded up and the base 20 is raised, the equipment is moved by the traction of the handle 22. The track 23 facilitates the movement of the equipment and avoids sinking into the ground with poor support. After reaching the corresponding position, one side is fixed by the damping support rod 21, the base 20 is lowered and fixed for support, the support plate 13 is extended by the deformation of the telescopic tube 12, the threaded rod 19 is rotated and raised to abut against the fixing plate 15 for fixation, the connecting tube is inserted into the U-shaped piece 4 and adjusted to the corresponding fixed radius size, and the fixing screw 5 is rotated and pressed down to squeeze. U-shaped piece 4 completes the pipe fixation. When the connecting pipe is made of soft material, it is then connected to the output end 10 through the plate at the placement platform 6 to complete the overall fixation. Motor 8 provides mechanical power for the water pump to pump water. The pump body 9 generates airflow through the output of motor 8, and negative pressure is generated at the input end 11 to draw water in, which is then discharged at the output end 10. Telescopic pipe 12 can be extended and retracted easily through deformation. Support plate 13 facilitates the support and fixation of the other end. Support crossbar 14 is fixed at support plate 16 to ensure the overall stability of telescopic pipe 12 and support plate 13, ensure the sealing of input end 11 and output end, and ensure the mechanical effect of water pump.
