Description

Technical Field

[0001] The utility model relates to the field of drainage systems, in particular to a novel safe and efficient submersible pump drainage system. Background Art

[0002] Currently, traditional submersible pump drainage systems primarily place the pump at the bottom of a submerged pool to drain water, making them suitable for clear water tanks. However, when draining water from mining pits, the high concentration of sediment and the deep sediment layer at the bottom can easily bury the entire pump, preventing safe drainage. During flood season, when drainage is urgent, time is wasted on sediment, reducing the actual discharge volume. Furthermore, the high sediment content can damage the drainage equipment, leading to frequent equipment failures, severely impacting drainage efficiency, and compromising production safety. Therefore, it is necessary to develop a solution to these problems. Utility Model Content

[0003] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a new type of safe and efficient submersible pump drainage system, which can effectively solve the problems of low drainage rate and high equipment failure rate of the existing submersible pump drainage system.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A new type of safe and efficient submersible pump drainage system includes an inlet filter float box, an inlet hose, a submersible pump and a drainage hose; the inlet filter float box includes a filter box and a connecting pipe, the filter box is connected to a main float that suspends the filter box in the water, the input end of the connecting pipe extends into the filter box, and the output end of the connecting pipe extends out of the filter box; the input end of the water inlet hose is connected to the output end of the connecting pipe; the input end of the submersible pump is connected to the output end of the water inlet hose; the input end of the drainage hose is connected to the output end of the submersible pump.

[0006] Preferably, the connecting pipe includes a straight tube body and a 90° elbow. The straight tube body is vertically arranged, and the lower end of the straight tube body is inserted into the filter box from the top of the filter box and maintains a distance from the inner bottom of the filter box. One end of the 90° elbow is connected to the upper end of the straight tube body, and the other end of the 90° elbow is provided with a flange, which is fixedly connected to the input end of the water inlet hose.

[0007] Preferably, the filter box is made of stainless steel wire mesh.

[0008] Preferably, two round steels are inserted into the upper end of the filter box and connected to a clamp through four rotating rods. The clamp clamps tightly hold the two main buoys and are locked by bolts.

[0009] Preferably, the main buoy is a cylindrical buoy.

[0010] Preferably, the water inlet hose is a metal corrugated hose.

[0011] Preferably, a clamp-type buoy is provided at the input end of the water inlet hose near the water inlet filter float box.

[0012] Preferably, the submersible pump has a motor cooling system, which includes a cooling water inlet pipe and a cooling water outlet pipe. The cooling water inlet pipe is connected between the motor of the submersible pump and the output end of the submersible pump, and the cooling water outlet pipe is connected between the motor of the submersible pump and the input end of the submersible pump.

[0013] Preferably, the input end of the submersible pump is arranged horizontally.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0015] By adopting the water inlet filter float box, the main float is used to suspend the filter box in the water. It moves with the water level and remains suspended in the water. It always follows the changes in the liquid level and always inhales the upper water quality. Since the upper water quality transported is relatively clean, the linkage control of the liquid level is often increased. When the water level reaches a high level, the water is discharged, and when the water level reaches a low level, the machine is shut down. The drainage impurity content is low, which can maintain normal drainage of the equipment and greatly reduce the equipment failure rate, thereby ensuring production safety and achieving efficient drainage.

[0032] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the present invention, including a water inlet filter float 10, a water inlet hose 20, a submersible pump 30 and a drainage hose 40.

[0033] The inlet filter buoyancy box 10 includes a filter box 11 and a connecting pipe 12. The filter box 11 is connected to a main float 13 that suspends the filter box 11 in the water. The input end of the connecting pipe 12 extends into the filter box 11, and the output end of the connecting pipe 12 extends out of the filter box 11. In this embodiment, the filter box 11 is made of a stainless steel wire mesh 101. Specifically, the filter box 11 includes an upper steel plate ring 111, a lower steel plate ring 112, and a plurality of support rods 113. The lower steel plate ring 112 is located below the upper steel plate ring 111. The plurality of support rods 113 are connected between the upper steel plate ring 111 and the lower steel plate ring 112 and are arranged in a circumferential manner. The stainless steel wire mesh 101 covers the upper steel plate ring 111, the lower steel plate ring 112, and the plurality of support rods 113. In addition, two round steels 114 are inserted into the upper end of the filter box 11, and are connected to a clamp 116 through four rotating rods 115. The clamp 116 clamps the two main floats 13 and is locked by bolts 117. In addition, the main float 13 is a cylindrical float. One end of the connecting pipe 12 extends into the filter box 11, and the other end of the connecting pipe 12 extends out of the filter box 11. Specifically, the connecting pipe 12 includes a straight tube body 121 and a 90° bend 122. The straight tube body 121 is vertically arranged, and the lower end of the straight tube body 121 is inserted into the filter box 11 from the top of the filter box 11 and maintains a distance from the inner bottom of the filter box 11. One end of the 90° bend 122 is connected to the upper end of the straight tube body 121, and the other end of the 90° bend 122 is provided with a flange 123.

[0034] The input end of the water inlet hose 20 is connected to the output end of the connecting pipe 12. In this embodiment, the flange 123 is fixedly connected to the input end of the water inlet hose 20. Furthermore, the water inlet hose 20 is a corrugated metal hose. A clip-on buoy 50 is installed at the input end of the water inlet hose 20, near the water inlet filter buoyancy tank 10. This is used to maintain uniform buoyancy and prevent tilting of the water inlet filter buoyancy tank 10, thereby keeping the water inlet filter buoyancy tank 10 stable and horizontal on the water surface. A liquid level linkage control is also installed to facilitate drainage stability.

[0035] The input end of the submersible pump 30 is connected to the output end of the water inlet hose 20. In this embodiment, the submersible pump 30 has a motor cooling system, which includes a cooling water inlet pipe 31 and a cooling water outlet pipe 32. The cooling water inlet pipe 31 is connected between the motor 33 of the submersible pump 30 and the output end of the submersible pump 30, and the cooling water outlet pipe 32 is connected between the motor 33 of the submersible pump 30 and the input end of the submersible pump 30. The output end of the submersible pump 30 is used for water inlet, and the cooling water outlet is then connected to the input end of the submersible pump 30, thus achieving circulating cooling and ensuring the normal operation of the motor 33 even in mud and sand or after emerging from the water. The input end of the submersible pump 30 is arranged horizontally, unlike the downdraft of traditional submersible pumps, which facilitates the installation of the water inlet hose 20.

[0036] An input end of the drainage hose 40 is connected to an output end of the submersible pump 30 .

[0037] The working principle of this embodiment is described in detail as follows:

[0038] During use, the entire filter box 11 can float on the water surface via two main floats 13. To adapt to the drainage of mining pits with high sediment content and the easy formation of sediment layers, two cylindrical main floats 13 are specially designed to float the entire filter box 11 on the upper layer of the water and ensure that the suction port maintains a certain submerged depth at the water surface. This submerged depth L can be designed based on the size of the suction port to ensure that the submersible pump 30 will not fall into the water due to air intake during operation, thereby preventing continuous drainage. By providing four rotating rods 115, the filter box 11 droops due to its weight. The rotating rods 115 are movable and rotatable. Under the vertical gravity, the main floats 13 will be pulled by the four rotating rods 115 and float horizontally on the water surface. The design depth of the suction port is calculated and designed, and the distance from the suction port to the bottom of the filter box 11 is also designed. This ensures that even if sediment accumulates and the filter box 11 runs aground, the sediment layer will not cover the suction port, maintaining a certain distance and protecting the suction port when the pump is stopped. As long as the liquid level reaches a certain level, the suction port will automatically move away from the sediment layer, making it ready for drainage at any time. At the same time, the submersible pump 30 is installed at the edge of the pool bottom to ensure that the submersible pump 30 can discharge water deep in the middle of the pool, and can still operate safely even when the water level drops and is exposed to the water surface, and can discharge to a lower required water level. When the submersible pump 30 is started, the water in the pool enters the filter box 11, and then the water passes through the connecting pipe 12, the water inlet hose 20, the submersible pump 30 and the drain hose 40 in sequence, and is then output from the output end of the drain hose 40.

[0039] The design focus of the utility model is: by adopting a water inlet filter float box, the main float is used to suspend the filter box in the water, and it moves with the water level and remains suspended in the water, always following the changes in the liquid level, and always sucking in the upper layer of water. Since the upper layer of water transported is relatively clean, the linkage control of the liquid level is often increased. The water level reaches a high level for drainage, and a low level for shutdown. The drainage has little impurity content, which can maintain normal drainage of the equipment and greatly reduce the equipment failure rate, thereby ensuring production safety and achieving efficient drainage.

[0040] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
