Hereinafter, various embodiments of the mobile heavy duty weapon 100 will be described in more detail with reference to FIGS. 2 to 11.

2 is a cross-sectional view in the A-A' direction of a mobile heavy gun according to an embodiment of the present invention.

Referring to FIG. 2, a neutralizing agent tank 150 containing a neutralizing agent powder 151 is fixed inside the outer housing 110 of the mobile neutralizer 100. Here, the neutralizing agent powder may be sodium bicarbonate powder. Sodium bicarbonate has high reactivity to acidic substances and is also stable during reaction. That is, sodium bicarbonate generates very low heat of neutralization even when reacting with an acidic substance, has little toxic gas generated in such a reaction, and has excellent neutralizing power, and is useful as a neutralizing agent powder.

Meanwhile, since the neutralizer powder 151 may be stored in the neutralizer tank 150 for a long period of time, preventing the neutralizer powder 151 from being hardened greatly affects the performance of the mobile neutralizer 100.

Accordingly, the mobile heavy duty weapon 100 according to the present invention includes a driving unit 170. The driving unit 170 may prevent the neutralizing agent powder from being fixed in the neutralizing agent tank 150 by moving the neutralizing agent tank 150.

For example, the neutralizing agent tank 150 may be fixed to the driving unit 170, and the driving unit 170 may be fixed to the inside of the housing 110.

The neutralizing agent tank 150 is connected to one end of the hose 140 through a connection pipe 162. One end of the hose 140 is connected to the neutralizing agent tank 150 so that the neutralizing agent powder provided from the neutralizing agent tank 150 may be ejected to the other end of the hose 140.

The control part of the control valve 130 is formed outside the housing 110. The control valve 130 is connected between the neutralizer tank 150 and the hose 140, and controls the injection of the neutralizer powder 151 in the neutralizer tank 150 as the user opens and closes the control valve 130. can do.

The neutralizing agent tank 150 includes a discharge pipe 152 through which the neutralizing agent powder 151 is sprayed, and the discharge pipe 152 may be connected to one end of the connection pipe 162. That is, one end of the connection pipe 162 may be connected to the discharge pipe 152 and the other end may be connected to one end of the hose 140.

The control valve 130 is connected to the connection pipe 162 and may operate to open and close the inside of a point of the connection pipe according to a user's opening and closing operation. Accordingly, spraying of the neutralizing agent powder 151 in the neutralizing agent tank 150 can be controlled.

3 is a cross-sectional view in the A-A' direction of a mobile heavy gun according to another embodiment of the present invention. The embodiment shown in FIG. 3 differs from the embodiment shown in FIG. 2 in the connection structure of the control valve.

Referring to FIG. 3, the control valve 130 is connected to the discharge pipe 152. The injection of the neutralizing agent powder in the neutralizing agent tank 150 may be controlled by opening and closing the inside of one point of the discharge pipe 152 according to the user's opening and closing operation on the control valve 130.

On the other hand, since the control valve 130 in the present invention is for controlling the injection of the neutralizing agent tank 150, in addition to the examples shown in FIGS. 2 and 3, various modified embodiments for controlling the injection of the neutralizing agent tank 150 These are possible, and these various modified embodiments will also be said to belong to the scope of the present invention.

4 and 5 are views for explaining an operation of a driving unit according to an embodiment of the driving unit.

4 and 5 illustrate the neutralization tank 150 provided inside the mobile heavy duty firearm 100 and the driving unit 170 for operating the neutralization tank 150 as viewed from the front of the neutralization tank.

4 is a diagram showing a state before the driving unit is operated.

First, referring to FIG. 4, a driving unit 170 is provided on one side of the neutralization tank 150, and the neutralization tank 150 and the driving unit 170 may be coupled to each other.

The bearing tube 161 is connected to the connection tube 162 and is not shown by being covered by the bearing tube 161, but the bearing tube 161 is connected to the discharge tube 152.

The driving unit 170 and the bearing tube 161 will be described in more detail below with reference to FIG. 5.

5 is a diagram illustrating a state in which a driving unit is operated.

5, the driving unit 170 may rotate and reciprocate the neutralization tank 150 at a predetermined angle.

The driving unit 170 is connected to one side of the neutralization tank 150, and a discharge pipe 152 may be formed on the other side of the neutralization tank 150 to face the position thereof. The discharge pipe 152 may be formed at a position corresponding to the center of the driving unit so as to be concentric with the rotational motion of the driving unit.

Accordingly, when the driving unit 170 rotates and reciprocates at a predetermined angle of the neutralizer tank 150, the discharge pipe 152 may rotate at the predetermined angle in response to the rotational reciprocation.

Therefore, even in this case, in order to perform the connection between the respective pipes, a bearing pipe 161 is provided.

One side of the bearing tube 161 is connected to the discharge tube 152, and the other side is connected to the connection tube 162. The bearing pipe 161 may have a bearing structure such that rotation of the first portion connected to the discharge pipe does not affect the second portion connected to the connection pipe. Therefore, in response to the rotational motion of the discharge pipe 152, a part is driven to rotate and the other part is fixed, and a bearing structure in close contact between the part and the remaining part is applied to flow into the connection pipe 162 without leakage of the neutralizing agent powder. Can be done.

6 is a cross-sectional view in the A-A' direction of a mobile heavy weapon according to another embodiment of the present invention. An embodiment shown in FIG. 6 relates to an embodiment in which a fluid tube 153 is applied in place of the bearing tube shown in FIGS. 4 to 5.

7 and 8 are diagrams for explaining an operation of a driving unit in another embodiment illustrated in FIG. 6.

6 to 8, a driving unit 170 is provided on one side of the neutralization tank 170, and a discharge pipe 152 is formed on the other side.

The discharge pipe 152 may be provided on the lower side of the neutralizing agent tank. That is, the discharge pipe 152 may be formed to be biased toward any one of the lengthwise directions of the neutralizing agent tank 150.

This is to facilitate spraying to the outside smoothly even when the residual amount of the neutralizing agent powder 151 is small by forming the discharge pipe 152 on the lower side of the neutralizing agent powder 151.

The driving unit 170 may reciprocate the neutralization tank 170 at a predetermined angle. Accordingly, the discharge pipe 152 formed on the lower side of the neutralizing agent powder 151 may be circularly moved at the predetermined angle by the rotational and reciprocating motion of the neutralization tank 170.

Therefore, in order to secure connectivity even in such a circular motion, the flowable pipe 153 is used in this embodiment.

The fluid tube 153 is a tube formed of a material having fluidity, and one side is connected to the discharge tube 152 and the other side is connected to the connection tube 162. Since the connection pipe 162 is fixed and the discharge pipe 152 can operate by an arc motion, the fluid pipe 153 can move or expand or contract in response to the movement of the discharge pipe 152.

For example, one end of the connection pipe 162 may be positioned to be concentric with the central axis of the rotational movement of the neutralization tank 170. In this case, even when the neutralization tank 170 reciprocates at a predetermined angle and the discharge pipe 152 reciprocates at a predetermined angle, the distance from the connection pipe 162 to the discharge pipe 152 is kept constant. Therefore, it is because the flexibility of the fluid pipe 153 is required to be less.

As another example, when the discharge pipe 152 performs a reciprocating arc motion at a predetermined angle according to the position of the connection pipe 162, the distance from the discharge pipe 152 to the connection pipe 162 may vary. In this other example, the flowable pipe 153 must have high elasticity, and for this purpose, a corrugated pipe structure or the like may be employed.

In the above, the description has been made on the premise that the driving unit rotates and reciprocates the neutralization tank at a predetermined angle in FIGS. 4 to 9, but the present invention is not limited thereto. For example, it is obvious that the driving unit is located under the neutralization tank and can perform various modifications such as vertical movement, left-right movement, or vertical movement of the neutralization tank.

Hereinafter, various embodiments of the driving unit will be described in more detail.

9 and 10 are diagrams illustrating an embodiment of a driving unit including an electronic function. 9 is a block diagram illustrating an embodiment of a driving unit.

Referring to FIG. 9, the driving unit includes a power supply unit 171, a timer unit 172, a residual amount detection unit 173, a control unit 174, a driving module 175, and an Internet On Things (IOT) linkage unit 176. can do.

The timer unit 172 provides a timer function, and the control unit 174 may set a time at which the neutralizer tank is driven by using a timer function provided by the timer unit.

The residual amount detection unit 173 may detect the residual amount of the neutralizing agent powder in the neutralizing agent tank. When it is determined that the residual amount of the neutralizing agent is less than the threshold amount, the control unit 174 may notify the user terminal through the IOT linking unit 176.

The driving module 175 may move the neutralizing agent tank 150 under the control of the controller 174.

FIG. 10 is a flow chart illustrating a driving method performed in an embodiment of the driving unit illustrated in FIG. 9, and an operation of the control unit will be described with reference to FIG. 10.

The control unit 174 checks the timer (S1010) and determines whether the mixing time has arrived (S1020). For example, the mixing time may be set to have a different cycle according to the temperature. For example, within a certain range, the operation may be performed in a first cycle, and at a high temperature exceeding the certain range, the operation may be performed in a longer period than the first cycle. In addition, at a low temperature less than the predetermined range, the operation may be performed in a shorter period than the first period.

When the mixing time arrives (S1020, YES), the control unit 174 controls the driving module 175 to rotate and drive the neutralization tank (S1030).

The control unit 174 may check the remaining amount of the neutralized powder in connection with the remaining amount detection unit 173 (S1040). When the remaining amount is less than the threshold amount (S1050, YES), the control unit 174 may control the IOT linking unit 176 to transmit a message of insufficient residual amount of neutralized powder to the user terminal.

In the above, an example of a driving unit including an electronic function has been described with reference to FIGS. 9 and 10. Meanwhile, according to an embodiment, the driving unit may be implemented as a simple mechanical structure.

FIG. 11 is a cross-sectional view in the A-A' direction of a mobile neutralizer illustrating a driving unit implemented with such a simple mechanical structure.

In the illustrated embodiment, the driving unit 170 may be driven by manipulation of the driving handle 180. The driving handle 180 can be fastened to the driving unit 170 from the outside of the housing 110 and can drive the driving unit 170 by a user's driving operation.

For example, the driving handle 180 may be fastened to and detached from the driving unit 170. Accordingly, when the neutralizer tank 150 is to be moved, the driving handle 180 may be fastened to the driving unit 170 to be used.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, but is limited by the claims to be described later, and the configuration of the present invention is varied within the scope not departing from the technical spirit of the present invention.
