Technical field:
The utility model relates to a kind of annunciator, is specifically related to a kind of truck hub high temperature alarm that is used for autotruck.
Background technology:
Autotruck in, in the long-distance transport, especially in hot weather, in the long-distance transport, brake system of car can cause damage to brake system of car because of fricative heat, particularly in the mountain area of geographical situation complexity, high-land, on, the downhill path is more, the apply the brakes time is longer, the heat energy of brake facing and automotive hub friction can not distribute fast, cause the temperature of automotive hub sharply to raise, and then make the friction coefficient of brake shoe brake cheek reduce, the deceleration and stopping performance decline, brake difficulty, meeting scaling loss brake facing when serious, heat energy is delivered to tire by the metal surface simultaneously, cause tyre temperature too high, have inducement very easily to cause slightly and blow out, cause taking place safety misadventure.Therefore, guarantee that autotruck effectively brakes, just must guarantee that the temperature of automotive hub can not be too high.For addressing this problem, traditional solution is that water cools off it when the automotive hub temperature is too high, promptly one water tank is set at the front apron or the operator's compartment top of automobile, side at automotive hub is installed a shower nozzle that is communicated with water tank, when the automotive hub temperature was too high, chaufeur was opened the valve water automotive hub is cooled off.But such cooling method is carried out by rule of thumb by chaufeur fully, assurance to temperature is not accurate enough, sometimes do not open cooling water expansion tank in the too high fashion of wheel hub temperature, sometimes valve is not closed as yet when not needing to cool off, cause the waste of water, what degree water in the while water tank uses has no way of finding out about it, and the anhydrous available situation of water tank takes place again and again when water; Stay major hidden danger to safe driving.
Summary of the invention:
The purpose of this utility model is: provide a kind of and can measure the automotive hub temperature automatically, the cooling of when the automotive hub temperature is too high, spraying water voluntarily, when dropping to normal value, the wheel hub temperature closes water cooling water voluntarily, and give the alarm during to setting value in the water tank water consumption, to remind the truck hub high temperature alarm of chaufeur moisturizing.
The utility model is to realize above-mentioned purpose by the following technical solutions:
The truck hub high temperature alarm, it is made of water tank, cooling water main, shower nozzle, temperature sensor, electromagnetic valve A, level sensor, controller, it is characterized in that: tank top is provided with water inlet, filtering net is housed in the water inlet, the tank wall of water tank bottom top one side is provided with the cooling water main, on the tank wall of cooling water main one side level sensor is housed, the termination of cooling water main is equipped with shower nozzle; On the cooling water main between shower nozzle and the water tank electromagnetic valve A is housed, described water tank bottom is provided with and cools off the emergency cooling water pipe that water main is communicated with, and electromagnetic valve B is housed on the emergency cooling water pipe; Electromagnetic valve A, electromagnetic valve B are connected with controller by lead respectively with level sensor; Controller is connected by lead and with temperature sensor.
Described controller is made of protective circuit, signal acquisition circuit, delay control circuit, comparator circuit, and protective circuit is connected with signal acquisition circuit, and signal acquisition circuit is connected with comparator circuit with delay control circuit respectively.
The beneficial effects of the utility model are:
This truck hub high temperature alarm is when the automotive hub temperature is higher, and temperature sensor can be transferred to controller with the temperature signal that detects, and starts electromagnetic valve A by controller and opens, and shower nozzle ejection cooling water expansion tank cools off wheel hub; When the automotive hub temperature was lower than setting value, controller cut out electromagnetic valve A, and shower nozzle stops water spray.Avoided existing cooling method to carry out by rule of thumb by chaufeur fully, to the not accurate enough problem of the assurance of temperature.When cistern water level drops to certain value, level sensor can pass to controller with the moisturizing signal, remind chaufeur to carry out moisturizing by controller, in case electromagnetic valve A breaks down, in the time of can not normally opening and closing, controller can start electromagnetic valve B, and cooling water expansion tank arrives shower nozzle by the emergency cooling water pipe wheel hub is cooled off, thereby reaches the purpose of safe driving.
Description of drawings:
Fig. 1 is the structural representation of truck hub high temperature alarm;
Fig. 2 is the principle of work block scheme of truck hub high temperature alarm.
Among the figure: 1, water tank, 2, the cooling water main, 3, shower nozzle; 4, temperature sensor, 5, electromagnetic valve A, 6, level sensor; 7, controller, 8, filtering net, 9, the emergency cooling water pipe; 10, electromagnetic valve B, 11, protective circuit, 12, signal acquisition circuit; 13, delay control circuit; 14, comparator circuit, 15, power supply, 16, indicator lamp.
The specific embodiment:
This truck hub high temperature alarm is made of water tank 1, cooling water main 2, shower nozzle 3, temperature sensor 4, electromagnetic valve A5, level sensor 6, controller 7, water tank 1 top is provided with water inlet, filtering net 8 is housed in the water inlet, be used for the filtration of cooling water expansion tank, prevent that its impurity from entering water tank 1 and the pipeline phenomenon of blocking takes place.The tank wall of top, water tank 1 bottom one side is provided with cooling water main 2, on the tank wall of cooling water main 2 one sides level sensor 6 is housed, and the termination of cooling water main 2 is equipped with shower nozzle 3; On the cooling water main 2 between shower nozzle 3 and the water tank 1 electromagnetic valve A5 is housed, water tank 1 bottom is provided with and cools off the emergency cooling water pipe 9 that water main 2 is communicated with, and electromagnetic valve B10 is housed on the emergency cooling water pipe 9.
Electromagnetic valve A5, electromagnetic valve B10 are connected with controller 7 by lead respectively with level sensor 6; Controller 7 is connected by lead and with temperature sensor 4.Controller 7 constitutes 14 by protective circuit 11, signal acquisition circuit 12, delay control circuit 13, comparator circuit, and protective circuit 11 is connected with signal acquisition circuit 12, and signal acquisition circuit 12 is connected with comparator circuit 14 with delay control circuit 13 respectively.Comparator circuit 14 also is connected with indicator lamp 16 on the controller 7.
When this truck hub high temperature alarm was implemented, water tank 1 was arranged on the top of the front apron or the operator's compartment of automobile.Shower nozzle 3 is arranged on a side of automotive hub, and temperature sensor 4 is installed on the baffle plate of automotive hub, near the inside face of wheel hub; Controller 7 is installed in the operator's compartment of automobile.Temperature sensor 4, level sensor 6 are connected with the signal acquisition circuit 12 of controller 7 respectively, and electromagnetic valve A5, electromagnetic valve B10 are connected with the delay control circuit 13 of controller 7 respectively; Power supply 15 adopts the automobile storage battery power supply, and is connected with the protective circuit 11 of controller 7.
