본 발명은 엔진의 냉각장치인 워터펌프에 관한 것으로서, 보다 상세하게는 베어링축에 조립된 풀리원통과 함께 가압봉체의 압전소자가 회전됨에 따라 압전소자에 원심력이 가해짐으로써 전류를 발생하게 되고 이 전류로 계기판상의 발광체를 점멸시켜 운전중에 워터펌프가 정상적으로 작동되는지 여부를 인지시킬 수 있도록 한 워터펌프의 회전정지 감지장치에 관한 것이다.The present invention relates to a water pump that is a cooling device of an engine, and more particularly, a centrifugal force is applied to the piezoelectric element to generate a current as the piezoelectric element of the pressure rod is rotated together with a pulley cylinder assembled to a bearing shaft. The present invention relates to a rotation stop detection device of a water pump that blinks an illuminant on an instrument panel to recognize whether the water pump is operating normally during operation.

일반적으로, 엔진의 냉각수를 순환시켜 주는 엔진의 냉각장치 일부분인 워터펌프는 소형의 송수량이 많고 출구를 좁혀도 압력이 올라가지 않아 온도조정이 용이하며, 냉각수는 자유로이 날개 사이를 흘러서 불안전하면서 자연순환하여 냉각되므로 곧바로 오버히트를 일으키지 않는 이점이 있다.Generally, the water pump, which is a part of the engine's cooling system that circulates the coolant of the engine, has a small amount of water and the pressure does not rise even when the outlet is narrowed, so it is easy to adjust the temperature, and the coolant flows freely between the blades, causing unsafe and natural circulation. Because of this cooling, there is an advantage that does not immediately cause overheating.

이러한 기술과 관련된 종래의 워터펌프(10)는 제1도 및 제2도에 나타낸 바와 같이 엔진(12) 일측의 크랭크축 풀리(14)와 베어링축 풀리(16)에 의해 V벨트(18)로 설치되어 있으며, 이는 펌프몸체(20) 내부에 베어링축(22)이 회전가능케 관통설치되어 있고 상기 베어링축(22)에는 다수의 날개(24)를 갖는 임펠러(26)가 장착되어 있으며, 그 다른 단부에는 베어링축(22)을 회전시키는 베어링축 풀리(16)가 장착되어 있다.The conventional water pump 10 related to this technique is connected to the V belt 18 by the crankshaft pulley 14 and the bearing shaft pulley 16 on one side of the engine 12 as shown in FIGS. 1 and 2. It is installed, the bearing shaft 22 is rotatably installed through the inside of the pump body 20, the bearing shaft 22 is equipped with an impeller 26 having a plurality of wings 24, the other The bearing shaft pulley 16 which rotates the bearing shaft 22 is attached to the edge part.

그러나, 상기와 같이 구성된 종래의 워터펌프에 있어서는 엔진(12)의 크랭크축 풀리(14)와 베어링축 풀리(16)에 의해 V벨트(18)로 구동시킴으로써 엔진 운전중에 V벨트(18)가 끊어지거나 느슨해지면 워터펌프(10)의 베어링축(22)이 회전되지 않게 되고, 상기 베어링축(22)이 회전되지 않으면 엔진이 과열되는 경우가 종종 발생되는 것이었다.However, in the conventional water pump configured as described above, the V-belt 18 is cut off during engine operation by driving the V-belt 18 by the crankshaft pulley 14 and the bearing shaft pulley 16 of the engine 12. If the bearing shaft 22 of the water pump 10 is not rotated when it is lost or loosened, the engine is often overheated if the bearing shaft 22 is not rotated.

본 발명은 상기한 바와 같은 종래의 제반 문제점을 해결하기 위해 연구개발한 것으로서, 본 발명의 목적은 베어링축 일측단의 풀리에 가압봉체 설치홈이 형성된 풀리원통을 마련하고 상기 가압봉체 설치홈에 베어링축의 외부측에 걸리도록 압전소자를 갖는 가압봉체를 설치하므로서 풀리원통과 함께 가압봉체의 압전소자가 회전됨에 따라 압전소자에 원심력이 가해져 전류를 발생하게 되고 이 전류로 계기관상의 발광체를 점멸시켜 운전중에 워터펌프가 정상적으로 작동되는지 여부를 인지시킬 수 있도록 한 워터펌프의 회전정지 감지장치를 제공하는데 있다.The present invention has been researched and developed to solve the conventional problems as described above, an object of the present invention is to provide a pulley cylinder formed with a pressure rod installation groove in the pulley at one end of the bearing shaft and bearing in the pressure rod installation groove As the piezoelectric element of piezoelectric element is rotated together with the pulley cylinder, the piezoelectric element of the piezoelectric element is applied to the outer side of the shaft to generate a current by applying centrifugal force to the piezoelectric element. The present invention provides a rotation stop detection device for a water pump that can recognize whether the water pump is operating normally.

상기와 같은 목적을 달성하기 위한 본 발명은, 펌프몸체 내부에 베어링축이 회전가능케 관통설치되며 상기 베어링축의 일측단에는 다수의 날개를 갖는 임펠러가 펌프몸체의 내부에 위치되게 장착되고 그 다른 단부에는 베어링축을 회전시키는 베어링축 풀리가 장착된 워터펌프에 있어서, 상기 풀리에 베어링축의 축직각방향으로 가압봉체 설치홈이 형성되고 그 외주면에 압전소자로부터 발생되는 전류가 흐르는 띠형접점이 형성된 풀리원통이 장착되며, 상기 풀리원통의 가압봉에 설치홈에는 일측단부에 베어링측 직경보다 크게 장방형홀이 형성되고 상기 장방형홀의 내부에 띠형접점과 연결된 압전소자를 갖는 가압봉체가 설치된 것을 특징으로 한다.The present invention for achieving the above object, the bearing shaft is rotatably installed through the inside of the pump body and an impeller having a plurality of wings is mounted to the inside of the pump body at one end of the bearing shaft and the other end In a water pump equipped with a bearing shaft pulley for rotating a bearing shaft, a pulley cylinder is formed in the pulley in which a pressing rod mounting groove is formed in the axially perpendicular direction of the bearing shaft, and a belt-shaped contact with a belt-shaped contact through which a current generated from a piezoelectric element flows on its outer peripheral surface. The pressing groove of the pulley cylinder is characterized in that a rectangular hole is formed in one side end of the pulley cylinder larger than the bearing side diameter and the piezoelectric element having a piezoelectric element connected to the belt-shaped contact is installed in the rectangular hole.

이하, 본 발명에 따른 워터펌프의 회전정지 감지장치를 바람직한 일실시예의 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the rotation stop detection device of the water pump according to the present invention will be described in detail by the accompanying drawings of a preferred embodiment as follows.

본 발명의 워터펌프는 제3도 및 제4도에 나타낸 바와 같이, 펌프몸체(20) 내부에 베어링축(22)이 회전가능케 관통설치되어 있으며 상기 베어링축(22)의 일측단에는 다수의 날개(24)를 갖는 임펠러(26)가 펌프몸체(20)의 내부에 위치되게 장착되고 그 다른 단부에는 베어링축(22)을 회전시키는 베어링축 풀리(16)가 장착되어 있다.In the water pump of the present invention, as shown in FIGS. 3 and 4, the bearing shaft 22 is rotatably installed inside the pump body 20, and a plurality of wings are provided at one end of the bearing shaft 22. FIG. An impeller 26 having a 24 is mounted so as to be positioned inside the pump body 20, and a bearing shaft pulley 16 for rotating the bearing shaft 22 is mounted at the other end thereof.

상기 베어링축 풀리(16)에는 절연재의 플라스틱으로 형성된 풀리원통(30)이 장착되어 있으며, 상기 풀리원통(30)은 베어링축(22)의 축직각방향으로 가압봉체 설치홈(32)이 형성되어 있고 그 외주면에는 압전소자(40)로부터 발생되는 전류가 흐르는 띠형접점(34)이 형성되어 있다.The bearing shaft pulley 16 is equipped with a pulley cylinder 30 formed of an insulating material plastic, the pulley cylinder 30 is formed with a pressing rod mounting groove 32 in the axially perpendicular direction of the bearing shaft 22 On the outer circumferential surface thereof, a band-shaped contact 34 through which current generated from the piezoelectric element 40 flows is formed.

상기 풀리원통(30)의 가압봉체 설치홈(32)에는 가압봉체(36)가 베어링축(22)의 축직각방향으로 이동가능케 설치되어 있으며, 상기 가압봉체(36)는 일측단부에 베어링축(22) 직경보다 크게 장방형홀(38)이 형성되어 있고 상기 장방형홀(38)의 내부에 띠형접점(34)과 연결된 압전소자(40)가 장착되어 있다.The pressurizing rod body 36 is installed in the pressurizing rod installation groove 32 of the pulley cylinder 30 so as to be movable in the axially perpendicular direction of the bearing shaft 22, and the pressurizing rod 36 has a bearing shaft at one end thereof. 22) The rectangular hole 38 is formed larger than the diameter, and the piezoelectric element 40 connected to the belt-shaped contact 34 is mounted in the rectangular hole 38.

상기 풀리원통(30)의 띠형접점(34)은 고정접점(42)과 접촉되어 있고 상기 고정접점(42)은 전선(44)을 통해 계기판(도시되지 않았음)상의 발광체(46)와 회로적으로 연결되어 있다.The belt-shaped contact 34 of the pulley cylinder 30 is in contact with the fixed contact 42, and the fixed contact 42 is connected to the light-emitting body 46 on the instrument panel (not shown) through the wire 44. Is connected.

상기와 같이 구성된 본 발명에 따른 워터펌프는, 엔진(12)의 크랭크축 풀리(14)와 베어링축 풀리(16)를 V벨트(18)로 연결한 상태에서 엔진(12)을 구동시키면 엔진(12)이 시동과 함께 베어링축 풀리(16) 및 베어링축(22)이 회전되게 된다.The water pump according to the present invention configured as described above, when the engine 12 is driven in a state in which the crankshaft pulley 14 and the bearing shaft pulley 16 of the engine 12 are connected with the V belt 18, the engine ( 12, the bearing shaft pulley 16 and the bearing shaft 22 are rotated together with the starting.

상기 워터펌프(10a)의 베어링축(22)이 회전되면 상기 베어링축 풀리(16)측 풀리원통(30)의 가압봉체 설치홈(32)에 설치된 가압봉체(36)는 베어링축(22)의 회전수에 상응하여 원심력을 받게 된다.When the bearing shaft 22 of the water pump 10a is rotated, the pressure rod body 36 installed in the pressure rod body installation groove 32 of the pulley cylinder 30 on the bearing shaft pulley 16 is connected to the bearing shaft 22. The centrifugal force is applied according to the rotation speed.

이때, 상기 가압봉체(36)의 장방형홀(38)에 장착된 압전소자(40)는 가압봉체(36)의 회전력과 상응하는 원심력만큼 압력이 가해지므로 일정한 전류를 발생하게 된다.At this time, the piezoelectric element 40 mounted in the rectangular hole 38 of the pressure bar 36 is applied with a centrifugal force corresponding to the rotational force of the pressure bar 36 to generate a constant current.

상기 압전소자(40)로부터 발생된 전류는 풀리원통(30) 외주면의 띠형접점(34)을 통해 풀리원통(30) 외측의 고정접점(42)과 전선(44)을 거쳐 발광체(46)에 흘러 빛을 발하게 되므로써 워터펌프(10a)가 정상적으로 작동함을 감지할 수 있는 것이다.The current generated from the piezoelectric element 40 flows to the light emitter 46 through the wire contact 44 and the fixed contact 42 outside the pulley cylinder 30 through the belt-shaped contact 34 on the outer circumferential surface of the pulley cylinder 30. By emitting light, it is possible to detect that the water pump 10a operates normally.

이와 반대로, 엔진(12)운전중에 V벨트(18)가 끊어지거나 느슨해져 워터펌프(10a)의 풀리(18)가 회전되지 않게 되면 풀리원통(30)의 가압봉체설치홈(32)에 설치된 가압봉체(36) 또한 회전되지 않아 원심력이 작용하지 않으므로 발광체(46)에 전류가 인가되지 않게 된다.On the contrary, if the V-belt 18 is broken or loosened while the engine 12 is running, and the pulley 18 of the water pump 10a is not rotated, the pressurized rod body installed in the pressurized rod installation groove 32 of the pulley cylinder 30 is not rotated. (36) Also, since the centrifugal force is not applied because it is not rotated, no current is applied to the light emitter 46.

그러므로, 운전자는 계기판에 설치된 발광체(46)는 소등된 상태이므로 워터펌프(10a)가 회전되지 않음을 감지할 수 있게 되고 엔진과열을 미연에 대처하여 방지할 수 있는 것이다.Therefore, the driver can detect that the water pump 10a is not rotated because the light emitter 46 installed in the instrument panel is turned off, and can prevent the engine overheating in advance.

이상에서와 같이 본 발명에 따른 워터펌프의 회전정지 감지장치에 의하면, 베어링축 일측단의 풀리에 가압봉체 설치홈이 형성된 풀리원통을 마련하고 상기 가압봉체 설치홈에 베어링축의 외부측에 걸리도록 압전소자를 갖는 가압봉체를 설치하므로서 풀리원통과 함께 가압봉체의 압전소자가 회전됨에 따라 압전소자에 원심력이 가해져 전류를 발생하게 되고 이 전류로 계기판상의 발광체를 점멸시켜 운전중에 워터펌프가 정상적으로 작동되는지 여부를 인지시킬 수 있는 효과가 있다.As described above, according to the rotation stop detection device of the water pump according to the present invention, a pulley cylinder having a pressure rod installation groove is formed in the pulley at one end of the bearing shaft, and the piezoelectric element is caught by the pressure rod installation groove to be caught by the outer side of the bearing shaft. As the piezoelectric element of the pressure bar is rotated together with the pulley cylinder by installing the pressure bar having the element, centrifugal force is applied to the piezoelectric element to generate a current, and this current blinks the light emitting body on the instrument panel, thereby operating the water pump during operation. There is an effect that can be recognized.

끝으로, 본 발명은 특정한 실시예에 관련하여 도시하고 설명하였지만 이외에도 등록청구의 범위에 의해 마련된 본 발명의 정신이나 분야를 벗어나지 않는 한도내에서 다양하게 개조 및 변화시켜도 본 발명의 기술범주에 속함을 밝혀두고자 한다.Finally, although the invention has been shown and described with respect to particular embodiments, it is intended that the invention belong to the technical scope of the invention without departing from the spirit and scope of the invention as set forth in the appended claims. I want to clarify.
