Sprinkler truck that protects the water pump by controlling the auxiliary engine with real-time water level measurement}

The present invention relates to a new concept technology that prevents damage due to operation of the water pump at low water levels by controlling the RPM of the auxiliary engine in an integrated controller based on real-time measurement information of the water level in the water tank at each stage.

In general, a sprinkler truck is a road management vehicle that sprinkles water on the road surface to prevent flying dust, performs water cleaning work, reduces the heat island effect of the road, and performs various water spraying tasks in road management. In addition, in the event of a fire, a tarpaulin can be used for extinguishing the fire.

A conventional sprinkler vehicle is equipped with a water tank at the rear, and front and rear sprinkler devices of the same length as the width of the water tank are installed at the front and rear of the water tank, respectively, at the lower ends of the front sprinkler device and the rear sprinkler device. It consists of spray nozzles attached at regular intervals.

Therefore, since the water contained in the water tank is sprayed through the sprinkler nozzle, dust generated on roads or construction sites can be removed by moving the sprinkler truck from the dust generating location.

Additionally, winter salt water is stored in the water tank and used for snow removal.

As prior art related to such a sprinkler vehicle, a pre-registered invention of the applicant of the present invention, “Patent Registration No. 2393341, title / sprinkler vehicle with improved spraying performance with spraying range and amount optimized for road surface conditions and types of foreign substances,” is disclosed. .

The above prior art significantly improves cleaning efficiency by minimizing water usage through variable control of the spray amount and increasing the impact force and discharge force by automatically adjusting the three-dimensional spray angle, height, and left and right rotation angle of the dual spray pipe. Provides effect.

In all conventional water sprinkler trucks, the water level inside the water tank cannot be known from inside the vehicle during work, so the work is finished and water is replenished using the buzzer of the low water level sensor. However, due to noise during operation, the low water level sensor buzzer is not recognized, so work is not stopped. In this case, a problem arises in which the water pump is damaged.

In addition, when returning to the water tank to replenish water, water is supplied over a long period of time, so if the timing when it is full is missed, water overflow occurs.

In addition, salt water remains in water tanks using winter salt water, so it is necessary to clean the salt when using it as landscaping water. However, there is currently no technology for cleaning the inside of the water tank.

The present invention is a means of solving the above-mentioned problem by installing a water level sensor capable of measuring the water level at each stage in the water tank, so that real-time water level information can be checked with the analog gauge and digital gauge provided in the integrated controller in the driver's seat through the sensor information at each stage. Develop technology to enable this.

In addition, the present invention seeks a technology to prevent water overflow by closing the automatic butterfly valve installed in the water supply pipe when the water level sensor detects a high level when pouring water into the water tank.

In addition, the present invention seeks a technology to automatically lower or stop the RPM of the auxiliary engine through step-by-step information from the water level sensor when transferring salt water or water stored in a water tank to another external reservoir.

In addition, in the present invention, when washing a water tank after using salt water, all water sprayed to the outside is blocked, and a plurality of washing spray bars installed inside rotate without power to spray water to clean the inside of the water tank. Develop technologies that enable you to do so.

According to the present invention, by checking real-time water level information in the water tank through the analog gauge and digital gauge provided in the integrated controller inside the sprinkler truck, the operator controls the amount of water sprayed to the outside by adjusting the RPM of the auxiliary engine for a long time. During this period, water can be sprinkled on the road.

In addition, when the integrated controller recognizes the sensing information before the low water level by the water level sensor installed in the water tank, it automatically reduces the RPM of the auxiliary engine by one level to prevent the auxiliary engine from stopping at high RPM, and detects the low water level by the water level sensor. (Last step) When the integrated controller recognizes the sensing information of the step, it automatically stops the auxiliary engine, preventing damage to the water pump.

In addition, the present invention not only prevents water overflow by closing the automatic butterfly valve installed in the buzzer and water supply pipe through sensing information from the water level sensor when the high level is reached even when receiving water from the water tank from the outside, but also prevents workers from waiting for a long time. This provides the effect of enabling more efficient work as you can do other work without leaving the vehicle unattended.

In addition, when transferring water or salt water stored in a water tank to the outside, when the integrated controller recognizes the sensing information of the pre-low water level stage and the low water level stage, it automatically reduces or stops the RPM of the auxiliary engine, so that the water pump is maintained even when transferring water or salt water. Provides the effect of preventing damage.

Moreover, in the present invention, when washing salt stuck to a water tank after using salt water, all water sprayed to the outside is blocked, and a plurality of washing spray bars installed in the water tank rotate without power to spray water, thereby damaging the inside of the water tank. It provides the effect of automatically cleaning salts on its own.

A preferred embodiment will be described to implement in more detail the means of solving the problem to be solved by the present invention.

Looking at the overall configuration according to a preferred embodiment of the present invention schematically based on the attached drawings, the water pump operating with the power of the auxiliary engine 2 mounted on the vehicle 1 is used to pump water or salt water stored in the water tank 3. In the water sprinkler (ST) that sprays water on the road surface by pumping,

It can be seen that it is largely divided into components of the water level sensor 10 installed on the top of the water tank 3, the analog gauge 21 and the digital gauge 22 provided in the integrated controller 20.

Hereinafter, the present invention comprised of the above schematic configuration will be described in more detail for ease of implementation.

A water level sensor 10 is installed, and the water level sensor 10 has a plurality of detection holes 12 spaced up and down on the support 11 inserted into the water tank 3 to enable step-by-step measurement. It is installed.

Therefore, the water level sensor 10 can provide granular sensing information such as low water level stage, pre-low water level stage, middle water level stage, and high water level stage.

An integrated controller 20 capable of controlling the sprinkler truck (ST) is installed inside the vehicle 1, and the integrated controller 20 includes an analog gauge 21 and a digital gauge 22 that display real-time water level information. By being provided together, the worker can easily check the water level of the water tank (3) in real time from inside the vehicle (1).

That is, the worker riding the vehicle (1) checks real-time water level information with the analog gauge (21) and digital gauge (22) through step-by-step sensing information by a plurality of detection holes (12), and based on this, the auxiliary engine ( By adjusting the RPM of 2), it is possible to spray water or salt water on the road for a longer period of time while appropriately controlling the amount of water or salt water sprayed to the outside.

Meanwhile, the sprinkler truck is basically equipped with a water supply pipe (4) that can receive water from the outside into the water tank (3), but it took a long time to fill the water, so workers waited until it was full or left it unattended, causing overflow. Technology is applied to solve the problems.

As a technical configuration for this, an automatic butterfly valve 30 is installed in the water supply pipe 4 as shown in FIG. 6, and when water is supplied through the water supply pipe 4 connected to the inside of the water tank 3, a water level sensor is used. When the detection port 12 of (10) detects a high water level, the automatic butterfly valve 30 is automatically closed to prevent water overflow, providing convenience to the operator without worrying about missing the timing.

In addition, the present invention provides that when transferring water or salt water to another external location through the transfer pipe 5 drawn out from the water tank 3, the detection port 12 of the water level sensor 10 is shown. As shown in 2, when it is sensed that the water level in the water tank (3) is at the pre-low water level stage, the sensing information at the pre-low water level stage is transmitted to the integrated controller (20) and displayed as an analog gauge (21) and digital gauge (22), and the integrated controller (20) ) recognizes this and automatically reduces the RPM of the auxiliary engine (2).

In addition, as the water level decreases further due to continued use of water, the detection port 12 of the water level sensor 10 senses that the water level in the water tank 3 is at the pre-low water level as shown in FIG. 3, and integrates the sensing information of this low water level. When the controller 20 recognizes this, it automatically stops the auxiliary engine 2, providing a special effect of preventing damage to the water pump.

Meanwhile, the water tank (3) of the present invention exhibits sufficient rigidity for high-speed driving and sudden stopping, and a plurality of breakwater plates (6) are installed at intervals inside to prevent sloshing, and the upper part is filled with water or salt water. Alternatively, a one-touch entrance (7) is installed through which the manager can enter the interior.

The rear spray bar and hose reel can be connected while exposed to the outside of the water tank (3).

Here, a washing water header pipe 50 is integrally connected to the upper side of the pressurized water branch pipe 41, and this washing water header pipe 50 is installed longitudinally on the inner upper side of the water tank 3, and the washing water On the front side of the header pipe 50, a plurality of washing spray pipes 51 are formed, located in each water storage space 3a partitioned with the breakwater plate 6 in between, while a plurality of washing spray pipes 51 are formed. By combining the washing spray bars 60 at the bottom of each, the washing spray bars 60 rotate and spray the wash water into each water storage space 3a through the plurality of spray nozzles 61 installed on the bottom, thereby forming the water tank 3. ) can be cleaned and removed by itself.

The method of cleaning the water tank (3) is to fill the water tank (3) with only 1/4 of water, block all paths of water spraying to the outside, and use the automatic butterfly valve (installed on the washing water header pipe (50)) When the auxiliary engine (2) and the water pump are operated with 52) open, the water is supplied to a plurality of washing spray bars (60) through the pressurization line (40), the pressurized water branch pipe, and the washing water header pipe (50) sequentially. As a result, the washing spray bar 60 rotates and sprays washing water to efficiently remove salts, and the washed water is collected inside the water tank 3 and then repeatedly circulated by the water pump to continuously perform the washing operation. .

Here, a technology that allows the washing spray bar 60 to rotate on its own without using separate power is additionally applied.

As a technical configuration for this, a rotating holder 54 is integrally screwed to the threaded portion 53 formed in the lower part of the washing water pipe 51 as shown in FIGS. 11 to 13, and the inside of the rotating holder 54 has upper and lower limits. A pair of sealing washers 55 are inserted, and a thrust bearing 56 is embedded between the pair of sealing washers 55.
