Abstract
The utility model relates to a kind of high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, comprise ultrasonic distance sensor, warning circuit, relay, it is characterized in that: described ultrasonic distance sensor one tunnel is connected with warning circuit circuit through amplifying circuit, another road is connected with the coil circuit of a relay through coil driver, and the normally closed interlock of described relay is series among wagon box electric control loop.The utility model can be realized three functions, distance measurement function, the not enough alarm function of distance, the not enough power down function of distance, install additional to evade just can realizing by manual control in the operational risk of high-altitude operation vehicle after this device and be transformed into the artificial and dual control of instrument, can operate high-altitude operation vehicle and the probability that by mistake touch porcelain vase reduces greatly.
Description
Technical field
The utility model relates to a kind of high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, is applied to substation equipment maintenance and repair.
Background technology
Service work often will be used high-altitude operation vehicle, has unavoidably in the wagon box drilling of Operation Van the danger that touches porcelain vase, at present for main visual inspection and the attention by operating personnel of evading of this type of risk.
The operation of operating personnel on wagon box unavoidably can intelligently desert, push the wrong action button, high-altitude operation vehicle also occasional there is the situations such as operation is malfunctioning, human factor and apparatus factor make the wagon box operation wrong potential risk of touching porcelain vase of operating personnel at high-altitude operation vehicle.Therefore, for the problems referred to above be the object of the utility model research.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, contributes to solve the false touch of existing work high above the ground wagon box and touches porcelain vase and have the phenomenons such as safety problem.
The technical solution of the utility model is:
A kind of high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, comprise ultrasonic distance sensor, warning circuit, relay, it is characterized in that: described ultrasonic distance sensor one tunnel is connected with warning circuit circuit through amplifying circuit, another road is connected with the coil circuit of a relay through coil driver, and the normally closed interlock of described relay is series among wagon box electric control loop.
The utility model has the advantage of: the utility model can be realized three functions, distance measurement function, the not enough alarm function of distance, the not enough power down function of distance, install additional to evade just can realizing by manual control in the operational risk of high-altitude operation vehicle after this device and be transformed into the artificial and dual control of instrument, can operate high-altitude operation vehicle and the probability that by mistake touch porcelain vase reduces greatly.
Brief description of the drawings
The control circuit schematic diagram of Fig. 1 the utility model embodiment.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the utility model relates to a kind of high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, comprise ultrasonic distance sensor, warning circuit, relay, described ultrasonic distance sensor one tunnel is connected with warning circuit circuit through amplifying circuit, another road is connected with the coil circuit of a relay through coil driver, and the normally closed interlock of described relay is series among wagon box electric control loop.
In implementation process, three parts of this device, Part I is ultrasonic distance-measuring sensor.In view of measuring distance in maintenance application be not far, measuring accuracy need not be very high and economical and practical etc. factor select ultrasonic distance-measuring sensor.Ultrasonic ranging also has the directional transmissions of being easy to, good directionality, intensity and is easy to the advantages such as control, its range measurement principle is that to utilize the aerial velocity of propagation of ultrasound wave be known 340m/s, when transmitter is launched ultrasound wave to a direction, in x time, start timing, ultrasound wave is propagated in air, in way, encounter barrier and just return immediately, receive that at receiver reflection wave just stops timing immediately, calculate the actual range of launching site to barrier according to the mistiming transmitting and receiving.
Part II is the not enough alarm device of distance.In the time that measuring distance is less than warning distance, comparator circuit output electrical signals is also connected warning circuit through amplifying circuit, and the buzzing alarm activation that device is connected to reminds operating personnel on wagon box to carry out risk averse.
Part III is the not enough breaker device of distance.In the time that measuring distance is less than the minor increment of device setting, the normally closed interlock of relay disconnects wagon box electric control loop, directly makes Operation Van's wagon box uncontrollable.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (1)
1. a high-altitude operation vehicle wagon box touch-proof porcelain vase warning device, comprise ultrasonic distance sensor, warning circuit, comparator circuit, relay, it is characterized in that: described ultrasonic distance sensor is connected with warning circuit circuit through amplifying circuit through comparator circuit Hou Yi road, another road is connected with the coil circuit of a relay through coil driver, and the normally closed interlock of described relay is series among wagon box electric control loop.
