Description

Submersible motor pump with surveillance camera {SUBMERGED MOTOR PUMP WITH SURVEILLANCE CAMERA}

The present invention relates to a submersible motor pump equipped with a surveillance camera, and more specifically, by configuring a surveillance camera inside the submersible motor pump, the internal malfunction of the underwater motor pump, leakage, failure, etc. can be easily grasped through the surveillance camera. The present invention relates to a submersible motor pump equipped with a surveillance camera which can prevent a large failure of the submersible motor pump due to a stop or malfunction of the submersible motor pump.

In general, the submersible motor pump is a pump in which the rotating part used for water supply and drainage is in the water, and the submersible motor pump is installed in the water purification plant or the wastewater treatment plant, or the water is stirred in the basement where the flooding is expected or the like. Submersible motor pump is installed to discharge the gas to the outside.

Since these submersible motor pumps are always in contact with water, the interior of the submersible submersible motor pump and the submersible submersible motor pump or the ground-mounted type are various.

Underwater motor pumps, which are used in the related art, are connected to a power supply when the water level reaches the on-switch and connects a power source to operate the submersible motor pump so that water can be drained. The impeller is rotated so that water flows in through the inlet and is discharged toward the outlet.

In addition, the discharge port is connected to a separate pipe, the water is discharged to the outside through the induction pipe extending to the outside.

The submersible motor pump operated by such an operation is that when the submersible motor pump operates and discharges water to the outside, the submerged motor pump which is submerged in the water is exposed to the atmosphere when the water level is lowered. During operation, since the heat is radiated by air cooling, overload occurs in the winding coil assembly according to the operation thereof, thereby degrading durability and shortening the life, or burning the coil due to overheating.

In addition, the submersible motor pump is introduced only into the lower inlet formed at the lower side of the stand housing when the impeller is operated and the water is introduced into the inlet so that the inflow of water is relatively small and the pumping amount per unit time is small. Many thrust loads are generated on the bearings, and the bearings are easily broken.

Therefore, in order to monitor these various occurrences from time to time, the sensor is further configured and used inside the submersible motor pump.

That is, the submersible motor pump is submerged in the water and the inside of the submersible motor pump can not be seen with the naked eye. Therefore, various sensors are configured inside the submersible motor pump. Whether the internal components of the pump is broken or the number of rotations of the shaft configured inside the submersible motor pump is being adjusted.

Looking at the technology of configuring the sensor inside the submersible motor pump, there was a submerged pump with a vibration sensor is registered Patent No. 10-0456065, which is an electric motor and as described in the claims of the registered notification In the submersible pump is fixed to the submersible pump consisting of an acceleration sensor that can detect the vibration of the shaft rotation to the submersible pump in the submerged operation underwater, the vibration sensor is a connection surrounding the bearing on the shaft top One box is installed in the horizontal direction and one in the horizontal and vertical direction of the bearing housing that surrounds the center bearing. The vibration sensor measures the vibration of the shaft in real time to effectively detect the abnormality of the submersible pump. We expect the effect to be checked.

In addition, an underwater motor pump configured with a leak detection sensor for detecting a leak in the connection box or a temperature sensor for detecting an internal temperature of the underwater motor pump is used.

However, the technology to configure the detection sensors inside the submersible motor pump to detect the failure of the submersible motor pump from the outside, the motor stops automatically when the internal leakage of the submersible motor pump or abnormal high temperature occurs, the submersible motor pump On the other hand, if a certain period of time has elapsed, the sensors installed inside will cause a failure, and accordingly, the underwater motor pump will not be able to be detected properly. There are additional problems that occur frequently.

The present invention has been made to solve the problems of the conventional submersible motor pump, by further comprising a surveillance camera that can monitor the inside of the submersible motor pump by monitoring the inside of the submerged motor pump, even if the detection sensor failure Through the video, it is possible to check whether there is a problem inside the submersible motor pump or to stop the pump operation quickly when the submerged motor pump is abnormal, and to extend the life of the submersible motor pump. The purpose is to provide a submersible motor pump equipped with a surveillance camera to prevent damage.

Submersible motor pump equipped with a surveillance camera of the present invention as a means for achieving the above object, the motor housing is inserted into the motor therein, a connection box coupled to the upper end of the motor housing, and is located at the bottom of the motor housing An underwater motor pump comprising a lower body including a rotating body installed on a motor shaft of the motor, a lower case including the rotating body in which the rotating body is built in, and a discharge port for discharging the fluid is discharged. A first bracket is further coupled to the outer circumference of the motor shaft, and is coupled to the first bracket to monitor an abnormality inside the motor by photographing the motor; The rotating body monitoring camera coupled to the first bracket for monitoring the abnormality of the rotating body by photographing the rotating body is further configured.

Inside the connection box, a second bracket is further coupled to the inner bottom surface of the connection box, and a connection box surveillance camera coupled to the second bracket to photograph the leakage of the connection box may be further configured.

In addition, the first bracket may further be coupled to the motor internal leakage detection sensor for detecting the leakage inside the motor, the second bracket may be further coupled to the connection box leakage detection sensor for detecting the leakage of the connection box.

In the present invention, the submersible motor pump equipped with a surveillance camera has a motor internal monitoring camera configured inside the motor housing in which the motor is configured, and thus the motor internal abnormality is frequently changed through an image captured by the motor internal monitoring camera. It is possible to monitor whether the submersible motor pump failure can be prevented in advance.

In addition, it is possible to quickly respond to the abnormality of the rotating body by the rotating body monitoring camera and the leakage of the connection box by the connection box monitoring camera at any time.

In addition, unlike the sensor, it is possible to check whether the underwater motor pump is abnormal through the captured image, so that it is possible to check the abnormality of the underwater motor pump more clearly.

In addition, as the detection sensors are further configured, it is possible to more reliably detect the failure and leakage of the submersible motor pump by the surveillance cameras and the detection sensors. It is possible to induce the extension of the life of the submersible motor pump as the monitor can visually check the abnormality of the submersible motor pump from time to time.
