Description

Technical Field

[0001] The present application relates to the technical field of trash interception devices, and more particularly to a trash interception device for the forebay of a pumping station. Background Art

[0002] The forebay of a pumping station is a key component in the pumping station system. It is located at the inlet of the pumping station, responsible for smoothing the water flow, evenly distributing it to the intake sump, and regulating the water level fluctuations. Sometimes it also undertakes the task of removing impurities to ensure the efficient operation of the water pump under stable conditions. In the forebay of the pumping station, a trash interception device is required to intercept debris in the water.

[0003] Currently, for related trash interception devices in the forebay of pumping stations, due to the lack of an integrated lifting structure, workers need to use tools to pick up and clean the impurities, which affects work efficiency. Moreover, there is a lack of a detachable trash interception structure. When the trash interception structure is damaged, the entire device needs to be replaced, increasing the maintenance cost. Summary of the Utility Model

[0004] To solve the problems raised in the above background art, the present application provides a trash interception device for the forebay of a pumping station.

[0005] The trash interception device for the forebay of a pumping station provided by the present application adopts the following technical solutions:

[0006] A trash interception device for the forebay of a pumping station includes a support frame, a limit frame, and a trash interception plate. One end of the trash interception plate is fixedly connected to a trash interception frame. One end of the trash interception plate at the top of the trash interception frame is fixedly connected to a threaded block. Both sides of the trash interception plate are fixedly connected with limit blocks. A fixing bolt is movably installed inside the limit block. Fixing frames are movably installed on both sides of the limit block. A limit groove is provided inside the fixing frame, and the limit block is fitted with the limit groove. Positioning blocks are fixedly connected to both sides of the fixing frame. A limit frame is movably installed outside the fixing frame. A positioning groove is provided inside the limit frame, and the positioning block is fitted with the positioning groove. The top of the limit frame is fixedly connected to a support frame.

[0007] The device is fixedly installed on the trash interception structure of the forebay of the pumping station. The cooperation between the trash interception plate and the trash interception frame can block debris, leaving the debris at the front end of the trash interception plate and the top of the trash interception frame, realizing the trash interception of the forebay of the pumping station. When it is necessary to clean the debris, an external structure or device is used to rotate or drive the threaded rod to rotate. The threaded block is internally provided with a threaded groove that meshes with the threaded rod. When the threaded rod rotates, the trash interception plate drives the trash interception frame to rise through the threaded rod, and the trash interception frame takes out the debris on its top, realizing the rapid salvage of the intercepted debris. When the trash interception plate or the trash interception frame is damaged, the fixing bolt is unscrewed, and then the trash interception plate is pulled upward to disassemble and replace the trash interception plate.

[0008] Preferably, one end of the limiting frame is fixedly connected with a fixing member, and a connecting bolt is movably installed inside the fixing member.

[0009] Connect the fixing member to the external pump station forebay structure, and then screw the connecting bolt into the space between the fixing member and the external pump station forebay structure, which increases the friction between the limiting frame and the external structure, and realizes the fixed installation of the device on the external pump station forebay structure for use.

[0010] Preferably, the top of the threaded rod is fixedly connected with a fixing ring, and a jack is provided inside the fixing ring.

[0011] Insert the external driving structure into the inside of the fixing ring, and then screw the external bolt into the space between the fixing ring and the external driving structure and penetrate the jack, so as to fix the external driving structure to the fixing ring.

[0013] Screw the fixing bolt into the inside of the fixing frame to make the fixing bolt engage with the threaded hole, which increases the friction between the fixing frame and the limiting block, and realizes the fixation of the fixing frame and the limiting block.

[0014] Preferably, there are four bolt holes provided inside the fixing plate around the threaded rod.

[0015] Connect the external driving structure mounting seat to the fixing plate, and then screw the external bolt into the space between the fixing plate and the external driving structure mounting seat and penetrate the bolt hole, so as to fix the external driving structure mounting seat to the fixing plate.

[0016] In summary, the present application includes the following beneficial technical effects:

[0017] By the combined use of the threaded rod, the trash rack and the trash rack frame, the blocked sundries can be quickly salvaged, without the need for staff to use tools to pick up and process the sundries, saving manpower and time, improving work efficiency, and making it more convenient for staff to process the sundries. And through the settings of the fixing bolt, the fixing frame and the limiting block, when the trash rack or the trash rack frame is damaged, the trash rack can be independently disassembled and replaced, without replacing the whole device, reducing the maintenance cost of the device.

Detailed implementation manners

[0023] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0024] An embodiment of the present application discloses a trash retaining device for a pumping station forebay. Referring to Figures 1-4 , a trash retaining device for a pumping station forebay includes a support frame 2, a limit frame 5 and a trash rack 7. One end of the trash rack 7 is fixedly connected to a trash retaining frame 8. One end of the trash rack 7 at the top of the trash retaining frame 8 is fixedly connected to a threaded block 11. Positioning blocks 603 are fixedly connected to both sides of the fixing frame 6. A limit frame 5 is movably installed outside the fixing frame 6. A positioning groove 501 is provided inside the limit frame 5, and the positioning block 603 is fitted with the positioning groove 501. The top of the limit frame 5 is fixedly connected to the support frame 2. The top of the support frame 2 is fixedly connected to a fixing plate 1. A threaded rod 3 is movably installed inside the fixing plate 1. The threaded rod 3 penetrates through the threaded block 11. When using the device, the staff fixedly installs the device on the trash retaining structure of the pumping station forebay. Both the trash rack 7 and the trash retaining frame 8 are composed of multiple rod structures, and flow channels are formed at intervals. The cooperation of the trash rack 7 and the trash retaining frame 8 can block sundries, so that the sundries stay at the front end of the trash rack 7 and the top of the trash retaining frame 8, and the water can pass through normally, realizing the trash retaining of the pumping station forebay. Connect an external rotating structure or driving device to the threaded rod 3. When it is necessary to clean the sundries, rotate or drive the threaded rod 3 to rotate. The threaded block 11 is internally provided with a threaded groove that meshes with the threaded rod 3. When the threaded rod 3 rotates, it can drive the threaded block 11 to drive the trash rack 7 to rise. At the same time, the positioning block 603 moves inside the positioning groove 501, which can guide and limit the rising direction of the trash rack 7, improving the stability effect of the movement of the trash rack 7. The trash rack 7 drives the trash retaining frame 8 to rise, so that the trash retaining frame 8 takes out the sundries on its top, realizing the rapid salvage of the blocked sundries, without the staff using tools to pick up and process the sundries, saving manpower and time, and being more convenient for the staff to process the sundries.

[0025] On both sides of the trash rack 7, there are fixed connection limit blocks 701. Inside the limit blocks 701, there is a fixed bolt 9 installed movably. On both sides of the limit blocks 701, there is a fixed frame 6 installed movably. Inside the fixed frame 6, there is a limit slot 602. The limit block 701 is fitted with the limit slot 602. When the trash rack 7 or the trash rack frame 8 is damaged or reaches the replacement life, the staff unscrews the fixed bolt 9, then pulls up the trash rack 7 upward to separate the limit block 701 from the fixed frame 6, and then the trash rack 7 can be disassembled and replaced. When installing a new trash rack 7, insert the trash rack 7 from top to bottom into the inside of the fixed frame 6, so that the limit block 701 is embedded into the inside of the limit slot 602. Finally, screw the fixed bolt 9 into the space between the limit block 701 and the fixed frame 6, which increases the friction force between the trash rack 7 and the fixed frame 6, and realizes the fixation of the trash rack 7 and the fixed frame 6, completing the installation of the trash rack 7.

[0026] Refer to Figure 1 , one end of the limit frame 5 is fixedly connected with a fixing piece 4, and inside the fixing piece 4, there is a connecting bolt 401 installed movably. Connect the fixing piece 4 with the external pump station forebay structure, and then screw the connecting bolt 401 into the space between the fixing piece 4 and the external pump station forebay structure, which increases the friction force between the limit frame 5 and the external structure, and realizes the fixed installation of the device on the external pump station forebay structure for use.

[0027] Refer to Figure 1 , the top of the threaded rod 3 is fixedly connected with a fixing ring 10, and inside the fixing ring 10, there is a jack. Insert the external driving structure into the inside of the fixing ring 10, and then screw the external bolt into the space between the fixing ring 10 and the external driving structure and penetrate the jack, then the external driving structure can be fixed with the fixing ring 10.

[0028] Refer to Figure 4 , inside the fixed frame 6 at the bottom of the limit slot 602, there is a threaded hole 601, and the fixed bolt 9 is threadedly connected with the threaded hole 601. Screw the fixed bolt 9 into the inside of the fixed frame 6 to make the fixed bolt 9 engage with the threaded hole 601, which increases the friction force between the fixed frame 6 and the limit block 701, and realizes the fixation of the fixed frame 6 and the limit block 701.

[0029] Refer to Figure 1 , inside the fixing plate 1 around the threaded rod 3, there are bolt holes 101, and there are four bolt holes 101. Connect the external driving structure mounting seat with the fixing plate 1, and then screw the external bolt into the space between the fixing plate 1 and the external driving structure mounting seat and penetrate the bolt holes 101, then the external driving structure mounting seat can be fixed with the fixing plate 1.

[0030] The implementation principle of a trash rack device for a pumping station forebay in an embodiment of this application is as follows: The device is fixedly installed on the trash rack structure of the pumping station forebay. The cooperation between the trash rack plate 7 and the trash rack 8 can block sundries, causing the sundries to remain at the front end of the trash rack plate 7 and the top of the trash rack 8, achieving trash racking in the pumping station forebay. When it is necessary to clean the sundries, an external structure or device is used to rotate or drive the threaded rod 3 to rotate. The threaded block 11 is internally provided with a threaded groove that meshes with the threaded rod 3. When the threaded rod 3 rotates, the trash rack plate 7 drives the trash rack 8 to rise through the threaded rod 3, and the trash rack 8 takes out the sundries on its top, realizing the rapid salvage of the blocked sundries. When the trash rack plate 7 or the trash rack 8 is damaged, the fixing bolt 9 is unscrewed, and then the trash rack plate 7 is pulled upward to disassemble and replace the trash rack plate 7. When installing a new trash rack plate 7, the trash rack plate 7 is inserted into the inner side of the fixing frame 6 from top to bottom, so that the limiting block 701 is embedded inside the limiting groove 602. Finally, the fixing bolt 9 is screwed into the space between the limiting block 701 and the fixing frame 6 to complete the fixed installation of the trash rack plate 7.
