Description
본 발명은 화학물질로부터 오염된 지역을 제독하는 제독차에 관한 것으로서, 좀 더 구체적으로는 제독시 화학약품과 함께 살수되는 물탱크로부터 물펌프를 구동시키는 제독차의 물펌프 구동장치에 관한 것이다.The present invention relates to a decontamination vehicle for detoxifying a contaminated area from chemicals, and more particularly, to a water pump driving apparatus of a decontamination car for driving a water pump from a water tank sprayed with chemicals during detoxification.
도 1은 종래의 구동장치가 구비된 제독차의 구성도로서, 유독 화학물질에 의해 특정지역이 오염됨에 따라 화학물질을 살포하여 유독 화학물질을 제독하는 제독차에는 밧데리(1)의 전원에 의해 엔진(2)이 구동함에 따라 마그네틱 클러치(3)에 의해 동력이 전달되면 물펌프(4)가 구동하여 물탱크(5)내의 물을 3방향밸브(6)의 절환에 따라 공급관(7a)(7b)을 통해 살수노즐(8a)(8b)측으로 공급하도록 되어 있고 여러 종류의 분체가 담겨진 분체탱크(9)에는 3방향밸브(10)의 절환에 의해 물탱크(5)내의 물이 공급관(7a)(7b)을 따라 선택적으로 공급시 분체를 투입하도록 되어 있으며 모터(11)의 구동에 따라 유화제를 투입하는 유화제 탱크(12)에는 3방향 밸브(13)의 절환에 의해 물탱크(5)내의 물이 공급관(7a)(7b)을 따라 선택적으로 공급시 유화제를 투입하도록 되어 있다.1 is a configuration diagram of a toxic vehicle equipped with a conventional driving device, the toxic chemical sprays chemicals as a specific area is contaminated by toxic chemicals, so that the toxic chemicals are decontaminated by the power source of the battery 1. When power is transmitted by the magnetic clutch 3 as the engine 2 is driven, the water pump 4 is driven to supply water in the water tank 5 according to the switching of the three-way valve 6 (7a) ( The water in the water tank (5) is supplied to the water spray nozzle (5a) by switching the three-way valve (10) to the powder tank (9), which is supplied to the water spray nozzle (8a) and (8b) side through 7b). Powder (7b) is to be selectively supplied in the supply and the emulsifier tank (12) into which the emulsifier is introduced according to the driving of the motor (11) in the water tank (5) by switching of the three-way valve (13) The water is adapted to introduce an emulsifier upon supplying selectively along the supply pipes 7a and 7b.
따라서 마그네틱 클러치(3)가 동작된 상태에서 엔진(2)이 구동하면 그 회전력이 타이밍벨트(14)를 통해 종동풀리(15)측으로 전달되어 물펌프 구동축을 회전시키게 되므로 물탱크(5)내의 물이 3방향 밸브(6)의 절환에 따라 공급관(7a)(7b)을 따라 선택적으로 공급된다.Therefore, when the engine 2 is driven while the magnetic clutch 3 is operated, the rotational force is transmitted to the driven pulley 15 through the timing belt 14 to rotate the water pump drive shaft, so that the water in the water tank 5 According to the switching of this three-way valve 6, it is selectively supplied along supply pipes 7a and 7b.
이러한 상태에서 분체탱크(9)에서 선택된 적어도 1개 이상의 분체가 투입됨과 동시에 모터(11)의 구동으로 유화제 탱크(12)내의 유화제가 공급되면공급관(7a)(7b)을 따라 선택적으로 공급되는 물에 분체 및 유화제가 희석되어 어느 하나의 분사노즐(8a)(8b)을 통해 살포되므로 오염된 지역을 제독하게 된다.In this state, when at least one powder selected from the powder tank 9 is introduced and the emulsifier in the emulsifier tank 12 is supplied by the driving of the motor 11, the water selectively supplied along the supply pipes 7a and 7b. Powder and emulsifier are diluted in the sprayed through any one of the injection nozzle (8a) (8b) to decontaminated the contaminated area.
그러나 이러한 종래의 제독차에서 엔진의 시동이나, 밧데리 충전시에는 물펌프를 구동시키지 않고 제독시에만 엔진의 동력을 물펌프 구동축에 전달하기 위해 마그네틱 클러치를 사용하게 되므로 다음과 같은 여러 가지 문제점이 있었다.However, in the conventional admiral vehicle, the magnetic clutch is used to transmit the engine power to the water pump drive shaft only when the engine is started without being driven by the water pump when the engine is started or the battery is charged. .
첫째, 제독차의 운용자가 마그네틱 클러치의 제어방법 및 그 시기를 숙지하고 있어야만 오염된 지역의 제독작업이 가능하게 되므로 담당자가 없는 상태에서는 신속한 제독작업이 불가능해져 오염지역이 확대될 우려가 있다.First, only when the operator of the admiral vehicle is familiar with the control method and the timing of the magnetic clutch, it is possible to decontaminate the contaminated area, so that the rapid decontamination work is not possible without a person in charge, and thus the contaminated area may be expanded.
둘째, 제독작업에 따른 물펌프 구동시 마그네틱 클러치를 구동시키기 위한 별도의 동력이 필요하게 되므로 용량보다 큰 엔진이 장착되어야 된다.Second, when driving the water pump according to the decontamination work requires a separate power for driving the magnetic clutch should be equipped with a larger engine than capacity.
셋째, 제어판에 마그네틱 클러치와 관련된 각종 램프 및 제어스위치가 추가되므로 인해 제어판의 회로구성이 복잡해지게 됨은 물론 제어판의 크기가 필요 이상으로 커지게 되므로 제어판의 구성에 많이 어려움이 수반되었다.Third, since various lamps and control switches related to the magnetic clutch are added to the control panel, the circuit configuration of the control panel is complicated, and the size of the control panel becomes larger than necessary, and thus the configuration of the control panel has been very difficult.
본 발명은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 고가의 마그네틱 클러치를 사용하지 않고도 제독작업시에만 물펌프가 구동하고 시동 또는 밧데리의 충전시에는 별도의 조작없이도 물펌프측으로 동력이 전달되지 않도록 하여 전문지식이 없는 운용자가 제독차를 신속하게 운용할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, the water pump is driven only during the decontamination work without using an expensive magnetic clutch, and power is transferred to the water pump side without any additional operation when starting or charging the battery. The purpose is to enable operators without expertise to operate admiral vehicles quickly.

도 2는 본 발명의 요부를 나타낸 종단면도이고 도 3a 및 도 3b는 도 2의 A - A선 단면도로서, 본 발명의 구성 중 종래의 구성과 동일한 부분은 그 설명을 생략하고 동일부호를 부여하기로 한다.Figure 2 is a longitudinal sectional view showing the main part of the present invention and Figures 3a and 3b is a cross-sectional view taken along the line A-A of Figure 2, the same parts as the conventional configuration of the configuration of the present invention to omit the description and to give the same reference numerals Shall be.
본 발명은 물펌프 구동축(16)에 드럼(17)이 고정되어 있고 상기 드럼의 일측으로는 엔진(2)의 구동으로 구동풀리의 회전력이 타이밍벨트(14)에 의해 전달됨에 따라 함께 회전하는 종동풀리(15)가 공회전가능하게 설치되어 있다.According to the present invention, the drum 17 is fixed to the water pump drive shaft 16, and one side of the drum is driven to rotate together as the rotational force of the driving pulley is transmitted by the timing belt 14 by the driving of the engine 2. The pulley 15 is installed to be idling.
그리고 구동풀리와 함께 회전하는 종동풀리(15)에 등간격으로 복수개의 공간부(18)가 형성되어 상기 공간부내에 드럼(17)과 근접되게 마찰패드(19)가 설치되어있고 드럼과 접속되는 마찰패드(19)의 반대편에는 중량체의 원심추(20)가 각각 고정되어 있으며 상기 원심추(20)와 종동풀리(15)사이에는 마찰패드(19)가 드럼(17)으로부터 이격되도록 하는 코일스프링과 같은 탄성부재(21)가 설치되어 있다.In addition, a plurality of spaces 18 are formed at equal intervals on the driven pulley 15 which rotates together with the driving pulley, and a friction pad 19 is installed in the space so as to be close to the drum 17 and connected to the drum. On the opposite side of the friction pad 19, a centrifugal weight 20 of the weight is fixed, respectively, and a coil for separating the friction pad 19 from the drum 17 between the centrifugal weight 20 and the driven pulley 15. An elastic member 21 such as a spring is provided.
본 발영의 일 실시예에서는 종동풀리(15)에 4개의 마찰패드(19)가 등간격으로 설치된 상태를 도시하였으나, 제독차의 크기에 따라 적절한 개수를 적용할 수 있으므로 반드시 이에 한정하지는 않는다.In the exemplary embodiment of the present invention, although the four friction pads 19 are installed in the driven pulley 15 at equal intervals, an appropriate number may be applied according to the size of the admiral vehicle, but is not necessarily limited thereto.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
먼저, 시동시 또는 밧데리(1)의 충전을 위해 엔진(2)이 느린 속도로 회전하면 엔진의 구동에 따른 회전력이 타이밍벨트(14)를 통해 종동풀리(15)측으로 전달되어 종동풀리가 회전하더라도 원심력이 약해 원심추(20)가 탄성부재(21)를 압축시키지 못하게 되므로 마찰패드(19)가 도 3a와 같이 드럼(17)과 접속하지 못하고 이격된 상태를 유지하게 되고, 이에 따라 물펌프(4)가 구동하지 않는다.First, if the engine 2 rotates at a slow speed at start-up or to charge the battery 1, even if the driven pulley rotates as the rotational force is transmitted to the driven pulley 15 through the timing belt 14. Since the centrifugal force is weak so that the centrifugal weight 20 does not compress the elastic member 21, the friction pad 19 is not connected to the drum 17 as shown in FIG. 3A and is kept spaced apart. 4) does not drive.
그러나 제독작업을 실시하기 위해 엔진(2)을 빠른 속도로 구동시키면 타이밍벨트(14)에 의해 동력이 전달되어 종동풀리(15)가 빠른 속도로 회전하게 되므로 원심추(20)에 원심력이 크게 작용하게 되고, 이에 따라 마찰패드(19)가 탄성부재(21)를 압축시키면서 축의 직각방향으로 이동하게 되므로 마찰패드(19)가 드럼(17)의 내주면에 긴밀히 접속된다.However, when the engine 2 is driven at a high speed in order to perform detoxification, power is transmitted by the timing belt 14 so that the driven pulley 15 rotates at a high speed so that centrifugal force acts greatly on the centrifugal weight 20. Accordingly, since the friction pad 19 moves in the direction perpendicular to the axis while compressing the elastic member 21, the friction pad 19 is closely connected to the inner circumferential surface of the drum 17.
이와 같이 엔진(2)의 고속 회전으로 원심력이 증대되어 마찰패드(19)가 드럼(17)의 내주면과 접속된 상태에서 계속해서 엔진(2)이 구동하면 물탱크(5)의 물펌프(4)가 구동하게 되므로 공급관(7a)(7b)을 통한 물의 공급이 가능해지게 되고, 이에 따라 전술한 바와 같은 동작에 의해 제독작업을 실시할 수 있게 된다.As the centrifugal force is increased by the high speed rotation of the engine 2 and the engine 2 continues to run while the friction pad 19 is connected to the inner circumferential surface of the drum 17, the water pump 4 of the water tank 5 ) Is driven, so that water can be supplied through the supply pipes 7a and 7b, and thus, detoxification can be performed by the above-described operation.
한편, 제독작업을 마치고 엔진(2)의 회전수를 감소시키면 드럼(17)의 내주면과 접속된 상태로 종동풀리(15)와 함께 회전하던 마찰패드(19)는 탄성부재(21)의 복원력에 의해 축방향으로 이동하여 드럼(17)으로부터 이격되므로 물펌프의 구동이 중단된다.On the other hand, when the number of revolutions of the engine 2 is reduced after the decontamination work, the friction pad 19 which rotates together with the driven pulley 15 in a state of being connected to the inner circumferential surface of the drum 17 is affected by the restoring force of the elastic member 21. By moving in the axial direction and spaced apart from the drum 17, the driving of the water pump is stopped.
즉, 운용자에 의한 별도의 조작없이 엔진(2)의 회전수를 조절하는 간단한 조작에 의해 물펌프(4)의 구동이 제어되는 것이다.That is, the driving of the water pump 4 is controlled by a simple operation of adjusting the rotation speed of the engine 2 without any separate operation by the operator.
이상에서와 같이 본 발명은 고가의 마그네틱 클러치를 사용하지 않음에 따라 다음과 같은 여러 가지 장점을 갖는다.As described above, the present invention has several advantages as follows, since an expensive magnetic clutch is not used.
첫째, 운용자가 물펌프를 작동시켜야 하는 경우와 그렇지 않는 경우에 따라 마그네틱 클러치를 제어할 필요가 없으므로 시동성이 용이하고 에너지 사용의 효율성이 증대된다.First, there is no need for the operator to control the magnetic clutch, depending on whether or not the operator needs to operate the water pump, so it is easy to start and the efficiency of energy use is increased.
둘째, 그 구조가 간단하여 제독차의 경량화가 가능해지게 됨은 물론 부품의 간소화로 제작에 따른 공정을 대폭 줄일 수 있게 된다.Second, the simple structure makes it possible to reduce the weight of the admiral vehicle, as well as greatly simplify the manufacturing process.
셋째, 물펌프의 구동에 따른 출력을 줄일 수 있게 되므로 엔진의 소형 경량화가 가능해진다.Third, it is possible to reduce the output according to the drive of the water pump it is possible to reduce the size and weight of the engine.
넷째, 제어판넬의 구성부품이 줄어들어 제어회로의 구성이 간단해지게 되므로 생산성을 향상시키게 된다.Fourth, since the components of the control panel is reduced, the configuration of the control circuit is simplified, thereby improving productivity.
