Description

Technical Field

[0001] This utility model is an integrated pump station with self-cleaning function, belonging to the field of integrated pump stations. Background Technology

[0002] An integrated pumping station is a highly integrated prefabricated drainage or water supply equipment that is manufactured in a factory and quickly installed on site. It is mainly used for sewage lifting, rainwater discharge, industrial wastewater treatment, and water supply allocation.

[0003] Existing integrated pump stations use a recessed structure at the bottom for cleaning the pump station's bottom surface. This structure utilizes the flushing force of the water flow during water intake to reduce the deposition of dirt. While this reduces the frequency of manual dredging, the water flow velocity is insufficient at the edges or corners of the recessed structure, which can easily lead to the formation of sediment accumulation zones. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated pump station with self-cleaning function. This solves the problem that existing integrated pump stations use a recessed structure at the bottom to clean the bottom surface, which reduces the accumulation of dirt by utilizing the flushing force of the water flow during water intake. Although this can reduce the frequency of manual dredging, the water flow velocity at the edges or dead corners of the recessed structure is insufficient, easily forming sediment accumulation areas.

The top end of the outlet pipe extends upward into the upper part of the pump station body and bends out through the upper outer wall of the pump station body. The part of the outlet pipe located inside the upper part of the pump station body is connected to the top end of the diversion pipe.

[0007] Furthermore, in order to reduce the deposition of dirt through the scouring force of water flow, the bottom surface of the main body of the pump station has a concave structure.

[0008] Furthermore, in order to guide the liquid used for flushing and cleaning, the flow-guiding maintenance platform includes a positioning ring and a fixing ring. The outer ring of the fixing ring is fixed to the inner wall of the middle part of the pump station body, and the positioning ring is located at the center of the fixing ring.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0017] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides an integrated pump station technical solution with self-cleaning function: its structure includes a base 1 and a hollow pump station body 2; the pump station body 2 is located on the upper end of the base 1, the lower part of the pump station body 2 is provided with a water inlet assembly 21, and the middle part of the pump station body 2 is provided with a self-cleaning water outlet assembly 22 connected to the water inlet assembly 21; the self-cleaning water outlet assembly 22 includes a vertically arranged diversion pipe 221, a flow guiding maintenance platform 222, a liquid level sensor 223, and a jet pipe 224. The diversion pipe 221 is connected to the upper edge of the flow-guiding maintenance platform 222. Several jet pipes 224 are provided and connected to the bottom surface of the flow-guiding maintenance platform 222 in a ring array so that the clean water output from the diversion pipe 221 is introduced into several jet pipes 224 through the flow-guiding maintenance platform 222. The bottom end of the jet pipe 224 is provided with a first high-pressure jet head 2241 that is inclined towards the bottom surface of the pump station body 2. The liquid level sensor 223 is located on the inner wall of the middle part of the pump station body 2.

[0018] The tilt angle of the first high-pressure injection head 2241 is 30°-60°, preferably 45°.

[0019] For water intake, the water intake assembly 21 includes an inlet valve 211, an inlet pipe 212, a guide plate 213, a submersible pump 214, and an outlet pipe 215 located on the lower inner wall of the pump station body 2. The inlet pipe 212 is located on the outer wall of the pump station body 2 and is connected to the inlet valve 211. The guide plate 213 is inclinedly located at the edge of the bottom surface inside the pump station body 2. The submersible pump 214 is located at the center of the bottom surface inside the pump station body 2. The bottom end of the outlet pipe 215 is connected to the output end of the submersible pump 214. The top end of the outlet pipe 215 extends upward to the upper part of the pump station body 2 and bends out through the upper outer wall of the pump station body 2. The part of the outlet pipe 215 located inside the upper part of the pump station body 2 is connected to the top end of the diversion pipe 221.

[0020] Among them, the guide plate 213 has a spiral or arc-shaped structure.

[0021] During operation, water flows through the inlet pipe 212 and the inlet valve 211 to the bottom of the pump station body 2. As the submersible pump 214 operates to pump water, under the positioning of the guide plate 213, the vortex generated when the submersible pump 214 starts will cause the sediment to be suspended, thus preventing siltation. The water will be introduced into the outlet pipe 215 and finally output from the upper outer wall of the pump station body 2.

[0022] In order to reduce the deposition of dirt through the flushing force of water flow, the bottom surface of the main body 2 of the pump station is a concave structure.

[0023] To guide the liquid used for flushing and cleaning, the flow-guiding maintenance platform 222 includes a positioning ring 2221 and a fixing ring 2222. The outer ring of the fixing ring 2222 is fixed to the inner wall of the middle part of the pump station body 2. The positioning ring 2221 is located at the center of the fixing ring 2222. A number of support plates 2223 are arranged in a ring between the outer ring of the positioning ring 2221 and the inner ring of the fixing ring 2222. An annular flow guiding cavity 2224 is provided in the interlayer of the positioning ring 2221. The outer side of the annular flow guiding cavity 2224 extends into the several support plates 2223 to form a diversion channel. The top end of the spray pipe 224 is connected to the bottom surface of the support plate 2223, and the bottom end of the diversion pipe 221 is connected to the top surface of one of the support plates 2223. The diversion pipe 221 communicates with the spray pipe 224 through the diversion channel.

[0024] The positioning ring 2221, the fixing ring 2222, and the support plate 2223 are integrally formed to improve the stability of the structure. The three will form a hollow disc-shaped structure through which the water outlet pipe 215 passes.

[0025] In order to clean the stains on the inner wall of the pump station body 2, the outer wall of the support plate 2223 is provided with a second high-pressure jet head 2225 with the output end facing the middle outer wall of the pump station body 2, and the input end of the second high-pressure jet head 2225 is connected to the diversion channel.

[0026] To improve the convenience of maintenance, an inspection port 23 is provided at the center of the top surface of the pump station body 2. A maintenance ladder 231 is vertically provided at the bottom of the inspection port 23. The bottom end of the maintenance ladder 231 extends through the center of the positioning ring 2221 and enters the lower part of the pump station body 2. The inner ring of the positioning ring 2221 is provided with a bolt structure that is fixedly connected to the maintenance ladder 231.

[0027] For ease of control, a solenoid valve 225 is provided at the top of the diversion pipe 221 to control the opening and closing of the diversion pipe 221.

[0028] It also includes a control cabinet 3, which is located at the top edge of the pump station body 2 to control the operation of the water inlet assembly 21 and the self-cleaning water outlet assembly 22, such as... Figure 3 As shown, the output end of the liquid level sensor 223 faces downward and is located in the concave structure to detect the liquid level. When the liquid level reaches half the height of the concave structure, the liquid level sensor 223 sends an electrical signal to the control cabinet 3, and the control cabinet 3 controls the solenoid valve 225 to open, so as to realize automatic periodic cleaning work.

[0029] During operation, as the diversion pipe 221 is opened, some of the water that was originally intended to be output to the outside will enter the diversion pipe 221. The downward-flowing water enters the annular guide cavity 2224, then enters the jet pipe 224, and finally is sprayed out through the first high-pressure jet head 2241 to flush the bottom surface of the concave structure of the pump station body 2, so as to prevent the formation of sediment accumulation areas at the edges or dead corners of the concave structure.
