Description

Technical Field

[0001] This utility model relates to the field of water tank cleaning, specifically a backwashing device for a water intake pump room water tank. Background Technology

[0002] In water supply and drainage projects, pumping stations typically have intake and suction tanks for water storage. However, during long-term operation, silt and impurities easily accumulate at the bottom of these tanks. If not cleaned promptly, this can lead to a decline in water quality, blockage of the intake pipes, and increased pump wear, thus affecting stable water supply. Currently, manual dredging is commonly used to remove sediment from the tank bottoms. This method is not only labor-intensive and inefficient, but also requires stopping pumping station operations, disrupting the continuity of water supply. Furthermore, manual dredging cannot clean the intake pipes, and prolonged neglect can cause blockages, leading to poor water intake or even complete cessation of water intake. Utility Model Content

[0003] The purpose of this utility model is to provide a backwashing device for a water intake pump room pool, which avoids the traditional manual sludge removal method. By stirring the mud and sand at the bottom of the intake pool and suction pool and discharging the mixed mud and water, the bottom of the pool is cleaned. At the same time, the water inlet pipe can also be backwashed.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A backwashing device for a water intake pump room includes several inlet pools, several suction pools, and a backwashing mechanism; the several inlet pools are arranged sequentially in the left-right direction, and a connecting port is provided between two adjacent inlet pools, with a water stop valve installed at the connecting port;

[0006] Several of the aforementioned water intake pools are arranged one-to-one with each other on the rear side of the water inlet pool, and the water intake pools are connected to the corresponding water inlet pools; each water inlet pool is equipped with a water inlet pipe on the front side, the front end of the water inlet pipe is connected to an external water source, and the rear end of the water inlet pipe is equipped with a quick-opening valve located in the water inlet pool.

[0007] Each water intake pool is equipped with a water pump at the rear, and the water pumps are connected to each other by a water supply network for supplying water to the outside, and the inlet end of the water supply network extends into each water intake pool.

[0008] The backwashing mechanism includes an electric branch valve, an electric main valve, and a flushing main pipe connected to the water supply network through the electric main valve. The flushing main pipe is located on the upper side of the inlet pool and the suction pool, and several flushing branch pipes corresponding to each suction pool and each inlet pool extend from the flushing main pipe.

[0009] The flushing branch pipe is connected to several downward-extending connecting pipes. The electric branch pipe valve is installed between the connecting pipes and the flushing branch pipe. Water flows through the connecting pipes to flush the bottom of the inlet pool or the suction pool, thereby agitating the sediment at the bottom of the inlet pool or the suction pool.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. By setting up a flushing main pipe, flushing branch pipe, connecting pipe and bend pipe, water flows through the bend pipe with the opposite water outlet direction and is injected into the bottom of the sludge inlet pool and suction pool. The water flow forms a vortex at the bottom of the pool to stir up the sediment at the bottom of the pool. By using the height difference between the water level in the pool and the external water source, the sewage in the pool is discharged to the external water source through the water inlet pipe in the opposite direction, thereby realizing the sludge removal of the pool bottom and the backwashing water inlet pipe.

[0012] 2. By setting up a level gauge, quick-opening valve, electric branch valve and electric main valve, when the water in the inlet pool reaches the preset backwash level, the level gauge is triggered and works with the quick-opening valve to discharge the water from the inlet pipe, thus achieving automatic sludge removal without manual intervention.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-4 The diagram shown is a schematic representation of an embodiment of a backwashing device for a water intake pump room pool provided by this utility model:

[0020] A backwashing device for a water intake pump room includes several inlet pools 1, several suction pools 2 and a backwashing mechanism; the several inlet pools 1 are arranged sequentially in the left-right direction, and a connecting port is provided between two adjacent inlet pools 1, and a water stop valve 4 is installed at the connecting port.

[0021] Several of the aforementioned water suction pools 2 are arranged one-to-one with each other on the rear side of the water inlet pool 1, and the water suction pool 2 is connected to the corresponding water inlet pool 1; each water inlet pool 1 is equipped with a water inlet pipe 5 on the front side, the front end of the water inlet pipe 5 is connected to an external water source, and the rear end of the water inlet pipe 5 is equipped with a quick-opening valve 6 located in the water inlet pool 1.

[0022] Specifically, a water passage is provided between the water intake pool 2 and the corresponding water inlet pool 1, and the water intake pool 2 and the corresponding water inlet pool 1 are connected through the water passage.

[0023] Each water intake pool 2 is equipped with a water pump 7 at its rear. Each water pump 7 is connected to a water supply network 8 for supplying water to the outside. The inlet end of the water supply network 8 extends into each water intake pool 2.

[0024] The backwashing mechanism includes an electric branch valve 31, an electric main valve 32, and a flushing main pipe 33 connected to the water supply network 8 via the electric main valve 32. The flushing main pipe 33 is arranged on the upper side of the water inlet pool 1 and the water intake pool 2, and several flushing branch pipes 34 corresponding to each water intake pool 2 and each water inlet pool 1 extend from the flushing main pipe 33.

[0025] The flushing branch pipe 34 is connected to several downward-extending connecting pipes 35. The electric branch pipe valve 31 is installed between the connecting pipe 35 and the flushing branch pipe 34. Water flows through the connecting pipe 35 to flush the bottom of the inlet pool 1 or the suction pool 2, thereby agitating the sediment at the bottom of the inlet pool 1 or the suction pool 2.

[0026] Specifically, in some embodiments, water flows directly out through the connecting pipe 35, and the discharged water flows in and out, impacting the sediment at the bottom of the inlet pool 1 or the suction pool 2, thereby mixing the sediment with the water flow.

[0027] The quick-opening valve 6 includes a valve body 61, a screw 62, and a hand-operated and electric-operated gate opener 63 for driving the screw 62 to move longitudinally. The side wall of the valve body 61 has a side valve port, and the bottom of the valve body 61 has a bottom valve port. The side valve port is connected to the water inlet pipe 5.

[0028] The hand-operated and electric gate opener 63 is installed on the top side of the inlet pool 1. The screw 62 is arranged vertically. The upper end of the screw 62 is connected to the hand-operated and electric gate opener 63, while the lower end of the screw 62 passes through the top of the valve body 61 and is fixed with a piston plate 65. The outer peripheral wall of the piston plate 65 is sealed to the inner side wall of the valve body 61 to block or open the bottom valve port.

[0029] The quick-opening valve 6 also includes a shaft guide 64, which is installed on the side wall of the water inlet pool 1 and is guided and engaged with the screw 62.

[0030] The bottom valve port is also connected to a downwardly extending lower pipe 66. Specifically, the lower pipe 66 is used to generate a siphon effect during the backwashing and sludge removal process. It can help discharge the mud and water at the bottom of the inlet pool 1 and enhance the flushing force of the backwash water flow in the water inlet pipe 5, thereby improving the sludge removal effect.

[0031] The external water source is a natural water body 100. The water inlet pipe 5 is set in a horizontal direction and is located below the normal water level of the natural water body 100. A level gauge 9 for measuring the water level inside the water inlet pool 1 is installed on the top of the water inlet pool 1. The measuring point of the level gauge 9 is located above the normal water level of the natural water body 100, and the level gauge 9 is electrically connected to the electric branch valve 31, the electric main valve 32, and the quick-opening valve 6.

[0032] Several standby pumps 10 are also installed on the rear side of the water intake pool 2, and the standby pumps 10 are connected to the water supply network 8.

[0033] Each flushing branch pipe 34 is connected to two connecting pipes 35, which are located on opposite sides of the corresponding water tank. The bottom of each of the two connecting pipes 35 is connected to a bend pipe 36, which is parallel to the bottom of the corresponding water tank and has opposite water outlet directions. The flushing water flows through the two bend pipes 36 to form a vortex at the bottom of the corresponding water tank.

[0034] Both the inlet pool 1 and the suction pool 2 are provided in two.

[0035] Preferably, the four corners of the inlet pool 1 and the suction pool 2 are rounded with concrete to reduce water flow resistance and facilitate the formation of vortices during backwashing.

[0036] The method of using this utility model includes the following steps:

[0037] S1: Open the quick-opening valve 6 and the stop valve 4. The external water source flows into the left and right water inlet pools 1 and the corresponding water suction pool 2 through the water inlet pipe 5. At this time, turn on the water pump 7 to pump water so that the water in the water inlet pool 1 and the water suction pool 2 is at the normal operating water level 102, so as to achieve continuous water supply to the outside.

[0038] S2: Close the water stop valve 4, then arbitrarily select one side of the water inlet pool 1 and its corresponding water suction pool 2 to form the sludge-to-be-dredged water pool, while the other side of the water inlet pool 1 and its corresponding water suction pool 2 form the water storage pool that supplies water to the sludge-to-be-dredged water pool.

[0039] S3: Close the quick-opening valve 6 in the dredging pool and the water pump 7 behind it to stop the water from entering and leaving the dredging pool; at the same time, open the electric main valve 32 on the flushing main pipe 33 and the electric branch valve 31 corresponding to the dredging pool, and then start the water pump 7 behind the storage pool to extract the stored water in the storage pool. The water flows through the flushing main pipe 33, the flushing branch pipe 34, the connecting pipe 35 and the bend pipe 36 in sequence and is injected into the dredging pool.

[0040] S4: Water flows through the bend pipe 36 with the opposite outlet direction and is injected into the bottom of the sludge-to-be-cleaned pool. It forms vortices in the inlet pool 1 and the suction pool 2 respectively to stir up the sediment at the bottom of the pool. When the water level in the inlet pool 1 rises to the preset backwash level 101, the level gauge 9 sends a signal to control the closure of the corresponding electric branch valve 31 and electric main valve 32.

[0041] S5: Open the quick-opening valve 6 corresponding to the pool to be dredged, and use the height difference between the water level in the pool and the normal water level of the external natural water area to discharge the muddy water in the pool into the river through the water pipe 5, and at the same time backwash the water pipe 5.

[0042] S6: After the water level in the dredging pool drops to the same level as the normal water level of the natural water body, the backwashing and dredging operation of the dredging pool is completed. Then, according to the above steps S1 to S5, the backwashing and dredging of the other side inlet pool 1 and suction pool 2 is carried out.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
