Problems solved by technology

In this product, the mechanical and electrical parts are independent, and the middle is connected by wires. It not only occupies a large area, but also has high cost and is difficult to install. The middle connecting wire is easily broken by external factors and the electric pump cannot work normally. Electric pump needs to move working position at any time
2. Many small submersible pumps are not equipped with electrical control cabinets
It is also difficult to turn off the submersible pump in a timely manner. The submersible pump is always in an aneroid and dry operation state, which wastes electric energy and damages the electric pump due to long-term dry operation.
3. In some working conditions, such as the excavation face of the tunnel, the excavation face of the mine tunnel, and some working environments of the construction work, it is difficult to install the liquid level controller and the liquid level sensor
In such an occasion, although some submersible pumps are provided with special care, it is difficult to start and shut down the electric pump in good time.
4. At present, there is a lever-type automatic submersible pump with floating balls, which is difficult to apply to tunnels and mine excavation working faces.

Embodiment 1

[0018] Such as figure 1 As shown, a sealed cavity is formed between the motor end cover 1 at the top of the submersible motor 3 and the motor outlet end cover 13, and the automatic control circuit 2 is assembled inside the sealed cavity. The output shaft of the submersible motor 3 is connected to the water pump assembly 6, the submersible motor 3 is provided with a string water jacket 4, the bottom of the string water jacket 4 is connected to the input port of the water pump assembly 6, the top is provided with a liquid outlet 9, and the upper liquid level sensor 5 is set on On the wall of the string water jacket 4 , the lower liquid level sensor 7 is arranged above the liquid inlet 8 of the water pump assembly 6 . A lifting ring 10 and a cable 11 are arranged on the top of the motor end cover 1 . The contact portion between the cable 11 and the motor end cover 1 is sealed and fixed.

[0019] The upper liquid level sensor 5 can adjust the height on the string water jacket 4 ...

Embodiment 2

[0023] figure 2 and figure 1 The difference is that a known float-type submersible pump is used, and the liquid outlet 9 of the water pump assembly 6 is arranged at the bottom position (certainly also as figure 1 set on the upper part), and set near the impeller of the water pump assembly 6. The upper liquid level sensor 5 is arranged on the floating ball 12 outside the submersible pump, and is connected to the automatic control circuit inside the motor end cover through a waterproof cable. Refer to the case where the upper liquid level sensor 5 is arranged outside the body figure 2 .

[0024] Working principle: Put the fully automatic submersible pump under the liquid surface of the working surface, and close the hand brake switch HK1. When the water storage level on the working face rises to the upper liquid level sensor 5 (P2), the upper liquid level sensor 5 sends a signal to the water level controller U1, and the water level controller U1 sends an instruction to con...

Abstract

The invention provides a fully automatic submersible pump, belonging to the mines and urban water supply and drainage fields where the pump is applied. The invention comprises a submersible motor, a water pump assembly, an automatic control circuit and an upper and lower liquid level sensor. The invention is characterized in that the automatic control circuit is connected into a whole with an engine body; the input terminal of the automatic control circuit is respectively connected with the upper liquid level sensor and the lower liquid level sensor and the output terminal thereof is connected with the main circuit of the submersible motor. The invention assembles the main parts which are electrically controlled into the submersible pump, cancels the original external electric control cabinet, greatly shortens the connecting lead, and solves the defects of lead breakage malfunction, special personnel required for watching, inconvenient installation, etc., through adopting the liquid level control technique of micro-electronics. The invention is suitable for drainage of tunnelling and the coal faces of mine gallery excavation and mining; furthermore, the invention is also suitable for drainage sites where the control cabinet can not be arranged and sites where the working location of the submersible pump is always moved.

Description

technical field [0001] The invention relates to a fully automatic submersible pump, which belongs to the field of pumps for water supply and drainage in mines and cities. Background technique [0002] At present, the submersible pumps used for drainage or sewage mainly have the following forms: 1. Automatic submersible pumps are generally composed of submersible drainage electric pumps and electrical automatic control cabinets. There are many wires connected in the middle, and there are liquid level sensors in the liquid pool. The liquid level sensor receives the signal of the upper and lower water levels, and transmits the signal to the liquid level controller of the control cabinet. The liquid level controller sends out a corresponding signal, implements the opening and closing of the electronic control components, and starts and closes the submersible pump through the wire. In this product, the mechanical and electrical parts are independent, and the middle is connected b...
