Description

[0001] The present invention relates to a vertical pump with monitoring equipment,

The present invention relates to a chopper pump having monitoring means, and more particularly, to a chopper pump having monitoring means for monitoring the driving state of each part of the pump remotely to predict the failure or the cause of the failure and to manage the pump Lt; / RTI > pump.

In particular, since a camera and a lighting device are provided, a clear image can be obtained even in a dark underground water tank or a city hall, so that it is possible to observe the state of a pump more accurately. In addition, a water detection sensor is provided inside the stir pipe box, By sensing the moisture, it is possible to prevent the ground motor from being damaged due to the damage of the stuffing box by the water in the channel pipe and to prevent the damage of the ground motor. In addition, a generator for generating electricity by water flow and a wireless communication module for image information transmission The present invention relates to a chopper pump provided with monitoring means for receiving electricity from the outside and for simplifying the structure without the need for wiring for transmitting signals.

The pump is a machine that transports liquid or gas fluid through a pipe by pressure action, or pushes fluid in a low pressure vessel through a pipe into a high pressure vessel. These pumps are structurally differentiated by reciprocating pumps, rotary pumps, centrifugal pumps, axial pumps, friction pumps, and other pumps.

Among these pumps are an underwater motor pump, which is always operated in a submerged state, and a main pump, which is placed on the ground and contains a guide casing and a propeller, which is used under water.

Among these pumps, the inlet pump is driven under the condition that the remaining parts except the motor are driven in the water. In order to check the driving state of the pump or the state or operation state of each constituent element constituting the pump, , There is a problem that it is difficult to maintain the pump because the pump must be taken out from the water and checked one by one.

That is, these pumps operate underwater, and various foreign substances such as sand, gravel, and wood chips are present in the water, and may be damaged due to such foreign substances or various other causes. In the case of such a pump failure, in order to ascertain the cause of the failure, it is necessary to lift the pump to the ground and disassemble the pump to find the cause. When such a pump is large in capacity, it takes much time and labor for lifting and disassembling, In the case of a pump installed at the same place as a pump station, there is a problem that the water floods while the pump is being replaced and the neighboring area is flooded.

Patent Literatures 1 and 2 disclose a technique related to a pump having a camera for detecting the internal state or operating state of the pump.

Patent Document 1 discloses a motor internal surveillance camera that further comprises a first bracket coupled to an outer periphery of a motor shaft of a motor formed inside a motor housing and coupled to the first bracket to photograph the motor to monitor an abnormality inside the motor, The present invention relates to a pump having a rotating body surveillance camera that is coupled to a first bracket and photographs the rotating body to monitor abnormality of the rotating body,

Patent Document 2 relates to a pump equipped with a camera whose structure is improved so that interference can be minimized with the flow of fluid inside the pump, and the pump can be firmly attached to photograph an accurate region.

However, such a conventional pump is operated in a state where it is installed in a basement such as a dark well, and when installed in such a dark place, the image taken by the camera is not clear, which deteriorates the monitoring function.

Particularly, in the case of a chopper pump, a longitudinal shaft connecting shaft is installed on a rotary shaft of a ground motor installed on the ground to pump water by rotating a propeller immersed in the shaft, and a large number of bearings are provided for supporting the long shaft. There is a problem that the mouth pump can not function due to aging of the bearing.

However, it has been difficult to check the condition of the equipment and to maintain it because the pump has to be used to lift the pump from a large capacity and it takes much time and manpower to disassemble.

It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

The present invention relates to a chopper pump equipped with a monitoring means and installed in a dark place of a deep well. The chopper pump is equipped with a camera (10) provided with a lighting means (11) .

The present invention pertains to a groundwater pump 100, which is installed on the ground in the same manner as a conventional chopper pump. A rotating shaft 200 connected to the motor shaft of the ground motor and having an intermediate portion rotatably supported by the bearing 200b; A propeller 300 installed at a lower end of the rotary shaft and rotated by the rotation of the ground motor to draw in water; A suction pipe (400) for guiding water sucked by the rotation of the propeller to a suction pipe; And a water pipe 500 installed to surround the rotary shaft and guiding the water sucked through the suction pipe to be discharged to the outside. The components are the same as those of the conventional chopper pump, and a detailed description thereof will be omitted. Only the parts deformed by the installation of the first embodiment will be described.

1, the camera 10 may be installed at various positions of the orbiting pump. However, as shown in FIG. 1, the state of the bearing 200b that rotatably supports the rotary shaft 200 connected to the motor shaft of the ground motor 100 And the propeller 300 or the inside of the suction pipe 400, which can be damaged by foreign matter contained in the pumped water, can be observed.

In addition, the orbiting pump has a long axis of rotation, and a pumping pipe 500 connecting two or more pipes is provided outside the long axis of the pivoting shaft. When a hole is formed in a part of the pumping pipe, Air is introduced and the pumping efficiency is lowered.

Therefore, it is preferable to install a camera 10 in a portion where a plurality of pipes constituting the pumping pipe 500 are connected to check whether external air is introduced into the pumping pipe.

1, the camera 10 includes an inner wall of a suction pipe 400 through which water is sucked by driving of a propeller, one side of a bearing 200b supporting a rotating shaft 200, As shown in Fig.

The camera 10 may be a kind of small-sized camera that is commonly used. A plurality of lighting means 11 is installed around the lens portion 10r at the center of the camera, I can do it.

As shown in FIG. 3, it is preferable that the lighting means 11 is installed at a plurality of positions around the lens portion 10r of the camera, but behind the lens portion 10r. When the illuminating means 11 is installed in front of the lens portion 11r of the camera, the light of the illuminating means 11 is directly irradiated to the lens portion so that the image is photographed excessively, so that a clear image can not be photographed.

2, the camera 10 has a camera fixing groove 400g formed on the inner wall of the suction pipe 500 and the inner wall of the suction pipe 400, and is installed inside the camera fixing groove 400g, It is desirable to prevent exposure from the walls.

Of course, a through hole may be formed in the wall so that a cable connected to the camera installed in the camera fixing groove 400g can pass through the hole. However, sealing should be performed so that water can not pass through the through hole.

As a structure for preventing water from passing through the through hole, a method of filling silicone, synthetic resin, or the like on the portion through which the cable passes can be used. However, as shown in FIG. 2, It is desirable to provide an anti-seal to prevent the camera body fixed to the camera fixing groove 400g from being separated from the camera fixing groove and to prevent water leakage.

In addition, in the case of a camera installed in the suction pipe 400 among the cameras installed in the orbiting pump, a transparent protective case 10c is further installed to protect the camera from foreign substances contained in the hydraulic pressure and water generated when the propeller is driven .

The orbiting pump is usually installed in a canal and a water collecting tank. The canal is formed in the ground by excavating the ground, and sand, soil, gravel or the like may be included in the water to be pumped. To the side of the water pipe 500 together with water.

The foreign substances moving together with the water may hit the inner wall of the suction pipe 400. When a part of the foreign substances comes in contact with the camera 10, the camera lens and the lighting means 11 are damaged as well as the camera, Or the lens is blurred to obtain a clear image.

As described above, a transparent protective case 10c having abrasion resistance and impact resistance is provided outside the camera 10 to protect the camera and the illumination means.

The transparent protective case 10c is made of a material such as high-strength glass or artificial diamond that does not cause scratches even when it comes into contact with sand or gravel, and can be formed into a hemispherical shape as shown in Figs. 2 and 3, . That is, it is preferable that the transparent protective case 10c serves as a lens so that the light irradiated from the illuminating means 11 can be evenly spread to all the regions photographed by the camera, and the photographing angle of the camera can be widened .

In addition, by forming the transparent protective case in a hemispherical shape, resistance to water sucked through the suction pipe can be reduced.

In the present invention, it is possible to observe an image photographed by a camera on the ground, and a monitoring means 20 is provided for this purpose.

The monitoring means 20 may be a display provided in a commonly used digital camera. Of course, a computer is connected to edit or reproduce the image displayed through the monitoring means 20, and the computer can be a normal computer having an image reproducing or editing function.

In order to transmit the image photographed by the camera 10 to the monitoring means, communication means must be provided between the camera 10 and the monitoring means 20, and the communication means may be the wireless communication module 60 .

As the wireless communication module 60, Bluetooth, Wi-Fi, etc., which are widely used for short-distance communication, may be used.

In addition, a generator 40 is provided as means for supplying power to the camera 10.

The generator 40 may be installed in a pumping water pipe or a suction pipe so as to be driven by a water stream of pumped water to generate electricity.

The generator 40 may be installed separately from the camera. Preferably, as shown in Figs. 2 to 4, a rotary vane 40w is formed on an edge of the surface of the protective case 10c constituting the camera from the camera lens portion, and the rotor 40r is provided inside the lens portion, And a stator 40s is provided so as to face the rotor.

That is, a camera accommodating space 40a is formed inside the protective case 10c, a camera 10 is installed in the space, and the protective case 10c protects the camera, The rotor 40r is rotated as the protective case is pushed by the pumped flow.

The generator 40 further includes a charger 50 for charging the electricity generated during operation of the pump by operating the pump.

In this case, since the image of the camera can not be vivid due to the flow of water while the pump is being driven, the mouth-hole pump having the generator 40 and the camera 10 stops the camera, It is desirable to be able to observe the state.

Of course, the generator 40 continuously generates electricity during the formation of the water flow by the driving of the pump, and the generated electricity is supplied to the charger 50 when the camera and the lighting means need to be driven.

The camera or generator is driven according to whether the pump is driven, and whether the pump is driven can be remotely instructed by the monitoring means. However, the other method is to install the water flow sensor 70 on one side of the camera, , The generator is driven when water flow is detected, and the camera is operated when no water flow is detected.

The present invention can also be applied to a centrifugal pump, an axial flow pump, a sludge pump, and the like.

Also, as described above, the camera provided in the pump shoots images of the inside of the suction pipe and the stuffing box, captures structural deformations of the propeller, presence or absence of foreign matter, or structural defects of the stuffing box and transmits them to the monitoring means 20, However, it is difficult to detect minute leaks that can be generated from the end portion of the stuffing box toward the flow pipe.

When the leaked water leaks in such a long time, corrosion is generated in the rotary shaft of the ground pump passing through the stuffing box, so that the rotational force of the ground motor can not be sufficiently transmitted to the propeller.

Accordingly, it is preferable that the moisture sensing sensor 30 is provided in the inner space of the stuffing box 600 to sense the inflow of water into the inside of the stuffing box 600.

The detection signal detected by the moisture sensor 30 is analyzed by a monitoring program provided in the monitoring means, and an alarm is generated when the reference signal reaches a predetermined moisture reference value.

In addition, the monitoring program provided in the monitoring means 20 can calculate the amount of change in the moisture detected by the moisture sensor 30, and when the amount of change in the calculated moisture is equal to or greater than a preset reference value, It is recognized that the water in the suction pipe suddenly flows into the stuffing box and the alarm is sounded, and then the driving of the pump can be stopped.
