In FIG. 1, a liquid antifreezing agent supply device A
Is a storage tank 1 as a storage portion for storing the liquid antifreezing agent L, one end serving as an inflow port 2a is connected to a lower portion of the storage tank 1, and the other end serving as a supply port 2b is connected to the storage tank 1
And the supply pipe 2 installed at a lower position than this
And a flow rate controller 3 for controlling the flow rate of the liquid antifreezing agent L, and an on-off valve provided downstream of the flow rate controller 3 of the supply pipe 2 for opening and closing the flow path of the supply pipe 2. The solenoid valve 4 and the supply pipe 2 are provided downstream of the solenoid valve 4,
It is composed of a pump 5 as an intermittent pressure-feeding means for intermittently pressure-feeding the liquid antifreezing agent L, and a system controller 11 for controlling the solenoid valve 4 and the pump 5.

When the power from the solar battery 12, the storage battery 13, and the solar battery 12 exceeds the power consumption, the system control unit 11 supplies the surplus power to the storage battery 13 to charge the storage battery 13, When the power from the battery 12 falls below the power consumption, the power controller 14 that supplies the shortage from the storage battery 13 to the timer 15 and the controller 16 described later.
The timer 1 outputs a drive signal to the control unit 16 or outputs a stop signal to the control unit 16 when the power is supplied from the power control unit 14 and the operation set time is reached.
5 and power is supplied from the power control unit 14, and the timer 15
The control unit 16 opens or closes the solenoid valve 4 based on the signal from the control unit 16 or starts and stops the pump 5 based on the signal from the timer 15.

2 (a) and 2 (b) are a plan view and a side view showing the installation state of the liquid antifreezing agent supply device shown in FIG. 1, respectively. In FIG. 2, R is a road,
d indicates a groove provided in the road R in the width direction. Reference numeral 20 denotes a casing that constitutes the liquid antifreezing agent supply apparatus A, which accommodates each part, and is configured to be openable and closable so that the liquid antifreezing agent L can be replenished into the storage tank 1 and is provided on the upper side. The solar cell 12 is arranged, and the supply port 2b side of the supply pipe 2 is projected to the lower side of the side surface. Reference numeral 21 denotes an installation table on which the housing 20 is placed and installed on the side of the road R. The supply port 2b of the supply pipe 2 is directed to the groove d of the road R.

Next, the operation will be described. It is assumed that the timer 15 is set to output a stop signal to the control unit 16 at 10 am and output a drive signal to the control unit 16 at 4 pm, for example. First, at 4:00 pm, the timer 15 outputs a drive signal to the control unit 16, so the control unit 16 outputs an open signal to open the solenoid valve 4, and intermittently outputs a drive signal to the pump. 5 is driven intermittently.

When the solenoid valve 4 is opened in this way, the pressure level difference H between the liquid level f of the liquid antifreezing agent L in the storage tank 1 and the pump 5 causes the supply pipe from the storage tank 1 to the pump 5. The liquid antifreezing agent L is supplied via the flow rate controller 3 with the flow rate adjusted by the flow rate controller 2. Then, by intermittently driving the pump 5, the liquid antifreezing agent L is intermittently supplied from the supply port 2b to the frozen road surface, and the snow and ice are in a sherbet state or a crispy state, which improves the road surface to be less slippery. It

Further, when the tire of the automobile passes over the liquid antifreezing agent L, the liquid antifreezing agent L is carried by the tire, so that the snow and ice road surface is further improved to the front. The frozen road surface is melted, and the liquid antifreezing agent L supplied to the groove d flows to the center of the road R along the groove d. Since the liquid antifreezing agent L exerts its effect up to a predetermined concentration, when the concentration becomes lower than the predetermined concentration, it will not exert its effect. Therefore, by repeatedly performing the above-described operation, the icy road surface is gradually improved to a slippery state to a distant place.

When the time has passed and it is 10:00 am, the timer 15 outputs a stop signal to the control section 16, so that the control section 16 outputs a closing signal to close the solenoid valve 4 and the pump 5 A stop signal is output to. Therefore, the liquid antifreezing agent L is not supplied to the road surface.

As described above, according to the embodiment of the present invention, since the flow rate controller 3 is provided in the supply pipe 2, the flow rate controller 3 can be adjusted so that the flow rate can be adjusted according to the installation location. Alternatively, by using the flow rate controller 3 having a flow rate according to the installation location, it is possible to effectively improve the frozen road surface to a non-slip state, and to consume the liquid antifreezing agent L more than necessary. Can be improved. Further, since the pump 5 is provided in the supply pipe 2, the liquid antifreezing agent L is supplied to the portion of the road surface through which the tire of the vehicle passes, and the liquid antifreezing agent L is transported to the tire of the vehicle, thereby freezing the road surface. It is possible to successively improve the non-slip state to a distant place, that is, in a wide range. Further, since it is not necessary to install a bleeding portion for cutting the road surface and supplying the liquid antifreezing agent L to the road surface, the liquid antifreezing agent supply device A is removed and the liquid antifreezing agent supply device A is removed in the unnecessary summer season.
Can be prevented from being damaged and deteriorated, and the landscape can be prevented from being damaged when the liquid antifreezing agent supply device A is unnecessary.

In the embodiment described above, the supply pipe 2 is provided with the flow rate regulator 3, the solenoid valve 4 and the pump 5, and the system control unit 11 controls the solenoid valve 4 and the pump 5. The supply device A is composed of a storage tank 1 and a supply pipe 2, and supplies the liquid antifreezing agent L to the road surface by the height difference H between the liquid level f of the liquid antifreezing agent L in the storage tank 1 and the supply port 2b. It may be configured. With such a structure, a power source such as a pump is not required, and it can be easily manufactured at low cost. Further, a liquid antifreezing agent supply device A is installed beside the road R, and the supply port 2b of the supply pipe 2 is provided on the road R.

In this way, the flow controller 3
If the on-off valve and the on-off valve are provided on the supply pipe 2, or if only the on-off valve is provided on the supply pipe 2, supply and stop of the liquid antifreezing agent L to the road surface can be easily performed by manually operating the on-off valve. You can control.

Although the pump 5 is exemplified as the intermittent pressure feeding means, the intermittent pressure feeding means is a compressed air producing mechanism which operates by a control signal from the control section 16, and the compressed air is supplied to the supply pipe 2 to prevent the liquid from freezing. The agent L may be pressure-fed to the road surface. In this case, it is necessary to provide a backflow prevention means so that the compressed air or the like does not flow back to the upstream side of the supply pipe 2. Further, although the description has been made assuming that one system such as the supply pipe 2 is provided, a plurality of systems may be provided and the supply flow rate of the liquid antifreezing agent L may be adapted to the installation location. Furthermore, the shape of the supply port 2b is not limited to a circle, but may be a shape that is sprayed in a mist shape, etc., depending on the installation location. Further, although the example in which the groove d is provided on the road R has been described, the same effect can be obtained without providing the groove d on the road R.
