Description

Outdoor fire hydrant valve spanner}

The present invention relates to an outdoor fire hydrant valve spanner, and more specifically, the main body in which the box wrench portion is formed on one side is formed to a certain length, and on the other side, a pressure handle that allows the user's downward pressure to act smoothly is formed, so that it can be used on an external water supply fire hydrant. This relates to an outdoor fire hydrant valve spanner that is not interfered with when opening and closing the valve due to the protective frame or safety frame installed to protect the surrounding fire hydrant, and can achieve stable valve opening and closing by appropriately balancing downward pressure and rotational force.

In general, after water pipes are buried underground, fire hydrants are installed at certain sections of the pipes to use fire extinguishing water in case of emergency fires and to discharge sediment and accumulated water in the pipes. For ease of maintenance, there are many above-ground fire hydrants located on the ground. It is being installed.

However, many expensive fire hydrants are damaged due to collisions with cars in urban areas and agricultural machinery, including cultivators, in rural areas.

Figure 1 is a diagram showing a protective frame installed on a general external water supply fire hydrant, and Figure 2 is a diagram showing a conventional outdoor fire hydrant valve spanner.

Referring to the drawing, in order to prevent the fire hydrant (1) from being damaged, a protection frame (2) is installed around the fire hydrant (1) at a certain distance as shown in Figure 1.

Accordingly, when attempting to use fire extinguishing water through the fire hydrant (1), the outdoor fire hydrant valve (3) must be rotated in the direction of opening. To open the outdoor fire hydrant valve (3), a spanner (4) as shown in FIG. 2 is used. In use, the spanner (4) is rotated with the outdoor fire hydrant valve (3) accommodated in the first valve receiving groove (5) or the second valve receiving groove (6) depending on the size of the outdoor fire hydrant valve (3). The outdoor fire hydrant valve (3) is opened or closed.

However, as shown in Figure 1, when the protection frame (2) or safety frame, etc. is installed around the fire hydrant, when the spanner (4) is rotated, interference with the protection frame (2) or safety frame occurs, preventing smooth rotation. A problem arises that makes it impossible to lose.

To solve this problem, some workers use a pipe range to open and close the valve, but when such a pipe range is used, wear or damage occurs as the outdoor fire hydrant valve is made of copper material with relatively low hardness.

Therefore, there is a need for improvement of a spanner for opening and closing outdoor fire hydrant valves that can smoothly open and close outdoor fire hydrant valves without interfering with the protective frame or safety frame around the fire hydrant.

Figure 3 is a perspective view showing an outdoor fire hydrant valve spanner according to an embodiment of the present invention, and Figure 4 is a cross-sectional view taken along line a-a' of Figure 3.

Referring to the drawing, the outdoor fire hydrant valve spanner 100 according to an embodiment of the present invention has a receiving groove (11a) formed on the lower bottom portion to correspond to the shape of the outdoor fire hydrant valve to accommodate the outdoor fire hydrant valve. The main body 10 is formed with a box wrench portion 11 that opens and closes the outdoor fire hydrant valve as it rotates, and is horizontally penetrated and received at a certain point on the upper side of the main body 10 so that it can slide laterally, and the main body 10 A rotation handle 20 that allows rotational force to be applied from the user when the body 10 is rotated, and a pressure handle 30 that extends upward and is coupled to the top of the main body 10 and allows a pressing force to be applied vertically downward from the user. It consists of

Here, the main body 10 is formed in a cylindrical or rectangular shape with a certain length, and a box wrench part 11 is formed on one side to accommodate and rotate an outdoor fire hydrant valve, and the pressure handle 30 is on the other side. are combined.

In addition, the box wrench part 11 is provided with a receiving groove 11a formed to closely accommodate the standardized outdoor fire hydrant valve in shape, and the box wrench part 11 constituting the receiving groove 11a is provided. On the inner wall surface, a close contact portion 11b is formed by repeating protrusions and grooves to increase the close contact.

Here, as the external water supply outdoor fire hydrant valve is formed in a hexahedral shape, the receiving groove (11a) must also be formed in a hexahedral shape to closely accommodate the hexahedral outdoor fire hydrant valve.

Meanwhile, at a certain point on the upper side of the main body 10, that is, on the coupling side with the pressure handle 30, a rotation handle 20 is provided that passes through the main body 10 laterally and is coupled to be able to slide laterally. .

This rotation handle (20) is provided as a means for applying rotational force when the user attempts to rotate the main body (10) accommodating the outdoor fire hydrant valve through the box wrench portion (11). This rotation handle (20) is received through one upper side of the main body 10, and is coupled so as to be able to slide laterally for the convenience of applying the rotational force considering the direction when the user wants to apply the rotational force in a specific direction.

That is, when the user wants to rotate the main body 10 clockwise, move the rotation handle 20 laterally to the right and pull the main body 10 to rotate clockwise, or, conversely, move it laterally to the left. The main body 10 can be pushed to rotate clockwise.

In this way, the direction of the lateral sliding movement of the rotation handle 20 will be freely determined depending on whether the user applies the rotational force by pushing or pulling when applying the rotational direction of the main body 10 and the corresponding rotational force.

This rotary handle (20) includes a cylindrical handle (21) that is partially accommodated through the main body (10) and moves laterally, and is formed on both ends of the cylindrical handle (21) to separate the cylindrical handle from the main body (10). It consists of a separation prevention stopper (22) that prevents (21) from being completely separated.

Here, the departure prevention stopper (22) is formed to have a larger diameter than the diameter of the cylindrical handle (21), so that when the rotary handle (20) moves laterally to the right or left to the maximum, it interferes with the departure prevention stopper (22) and no longer moves laterally. It is configured so that it cannot be moved.

In addition, the length of the rotation handle 20 is preferably equal to or greater than the height of the main body 10, and the height of the main body 10 according to an embodiment of the present invention is preferably 150 mm or more. Accordingly, if the main body 10 is 150 mm, the length of the rotating handle 20 should be at least 150 mm.

Meanwhile, the pressing handle 30 is provided so that a pressing force is applied vertically downward from the user. The vertical downward force through the pressing handle 30 is applied to the main body 10 when the rotational force is applied through the above-described rotating handle 20. The fire hydrant valve accommodated in and in close contact with the box wrench part 11 is prevented from being separated from the box wrench part 11.

In other words, since the direction of rotation through the rotation handle 20 is horizontal, when a large pressing force acts in the horizontal direction, the outdoor fire hydrant valve may be separated from the box wrench part 11. To prevent this separation, the user must apply rotational force. At the same time, a vertical downward force is applied through the pressure handle (30) so that the outdoor fire hydrant valve can be rotated without being separated from the box wrench part (11).

This pressure handle 30 is composed of a connection part 32 extending on the upper surface of the main body 10, and a pressure plate 31 connected to the upper surface of the connection part 32 and formed in the shape of a horizontal disk.

Here, the pressure plate 31 is formed in the shape of a horizontal disk as an example in the drawing, but of course it can also be formed in the shape of a horizontal plate.

Figure 5 is a perspective view showing an outdoor fire hydrant valve spanner according to another embodiment of the present invention, Figure 6 is an exploded perspective view of Figure 5, and Figure 7 is a cross-sectional view taken along line c-c' of Figure 5.

Referring to the drawing, the outdoor fire hydrant valve spanner 200 according to the present embodiment largely has a rotation handle 111 and a pressure handle 120 extending on one upper side and an upper surface, respectively, and at least one coupling bracket on one side of the lower outer surface. The main body 110 on which (130) protrudes, and the bracket seating portion 143, which accommodates a certain portion of the main body 110 and allows the coupling bracket 130 of the main body 110 to be seated, has different heights. A plurality of them are spaced apart, and a receiving groove (144a) is formed on the lower bottom to correspond to the shape of the outdoor fire hydrant valve. A box wrench part (144) is formed to open and close the outdoor fire hydrant valve as it rotates while accommodating the outdoor fire hydrant valve. ) is configured to include a receiving body 140 that is formed.

Here, the main body 110 is partially accommodated in the receiving body 140, and the overall height of the outdoor fire hydrant valve spanner 200 is determined depending on the height of the accommodated main body 110.

That is, this embodiment is configured to adjust the height of the outdoor fire hydrant valve spanner 200, and is an outdoor fire hydrant valve spanner that can stably open and close the outdoor fire hydrant valve according to the height of the protective frame or safety frame installed on the external water supply fire hydrant. It can be adjusted to a height of (200).

For example, if the height of the protective frame or safety frame is formed to be approximately 200 mm higher than the height of the outdoor fire hydrant valve, the height of the outdoor fire hydrant valve spanner 200, which can stably rotate the outdoor fire hydrant valve, should be approximately 300 mm or more.

This means that the height of the rotating handle 111 from the bottom of the receiving body 140 must be higher than 200 mm so that interference does not occur when rotating the rotating handle 111. Therefore, at least the height of the rotating handle 111 from the bottom of the receiving body 140 must be higher than 200 mm. The height should be higher than 200mm.

Of course, the height of the rotary handle 111 from the bottom of the receiving body 140 is 200 mm, and when the rotary handle 111 rotates, it may contact the protection frame or safety frame, so a margin must be left, and the preferred margin is 50mm or more would be appropriate.

Therefore, in this embodiment, since the height of the protective frame or safety frame may be different for each external water supply hydrant that needs to open and close the outdoor fire hydrant valve, an appropriate outdoor fire hydrant valve spanner is installed in consideration of the height of the protective frame or safety frame installed on the corresponding fire hydrant at the site. It is configured to selectively control (200).

To this end, a plurality of bracket seating parts 143 are formed at different heights and spaced apart from each other in the receiving body 140 to adjust the receiving height of the main body 110. The plurality of bracket seating parts 143 are formed on the receiving body 140. It is formed in the height direction of 140 and is formed on both sides from the vertical cut portion 141 so that the coupling bracket 130 of the main body 110 can move vertically.

In addition, a horizontal cut part 142 is formed in the horizontal direction on the vertical cut part 141. This horizontal cut part 142 is formed to accommodate the coupling bracket 130 when rotated in the horizontal direction, and the horizontal cut part 142 is formed to accommodate the coupling bracket 130 when rotated in the horizontal direction. A bracket seating portion 143 is formed on the lower side of the portion 142 to support the coupling bracket 130.

Here, at least one coupling bracket 130 is formed to protrude on the lower outer peripheral surface of the main body 110. This coupling bracket 130 is a protrusion 131 that protrudes vertically onto the outer peripheral surface of the main body 110. ) and a horizontal extension portion 132 that extends vertically on both sides from the protrusion 131 and is formed so that the outer peripheral surface and the inner peripheral surface of the receiving body 140 have the same curvature.

That is, the horizontal extension 132 rotates in contact with the outer peripheral surface of the receiving body 140 when the main body 110 rotates at a certain angle, and the horizontal extension 132 and the protrusion 131 accommodate as they rotate at a certain angle. It is seated and supported on the bracket seating portion 143 of the body 140.

Such bracket seating portions 143 are formed in three locations in FIGS. 5 and 6, but if it is desired to set the height adjustment in more detailed settings, more than three locations can be formed.

In addition, the horizontal extension part 132 extends vertically from the protrusion 131 to both the left and right, which means that the horizontal cut part 142 and the bracket seating part 143 extend left and right with respect to the vertical cut part 141. , formed for the same reason as those formed on both sides of the right.

That is, the outdoor fire hydrant valve spanner 200 according to the present embodiment is formed in multiple stages along the height direction to adjust the height of the entire outdoor fire hydrant valve spanner 200 in which the main body 110 and the receiving body 140 are combined. Among the bracket seating parts 143, the coupling bracket 130 of the main body 110 is rotated at a certain angle so that it is supported on the bracket seating part 143 of the user's desired height. At this time, the direction of rotation is the external water supply to be opened and closed. The outdoor fire hydrant valve must be rotated taking into account the rotation direction.

That is, if you want to rotate the outdoor fire hydrant valve counterclockwise, the bracket seating portion 143 on which the coupling bracket 130 is seated will be the side on which the main body 110 is seated when rotated counterclockwise, If you want to rotate the outdoor fire hydrant valve clockwise, it will be the side that is seated when the main body 110 is rotated clockwise.

Therefore, in order to rotate the outdoor fire hydrant valve clockwise or counterclockwise, the bracket seating portion 143 on which the coupling bracket 130 of the main body 110 is seated in each direction is located on the left or right side from the vertical cut portion 141. It is decided on one of the following.

Meanwhile, in this embodiment, the main body 110 is formed with a rotation handle 111 and a pressure handle 120 as in the above-described embodiment, and the pressure handle 120 includes a pressure plate 121 and a connection portion 122. do.

In addition, as the main body 110 and the receiving body 140 are rotationally coupled and accommodated with each other, the main body 110 is formed into a cylindrical shape, and the inner receiving space of the receiving body 140 that accommodates it is also cylindrical. It is formed as a statue.

In addition, the coupling brackets 130 formed on the main body 110 can be formed in a pair as shown in Figures 5 to 7 to increase coupling strength, and can also be formed in three or more pieces for higher coupling strength. Of course you can do it.

Of course, in this case, the vertical cut portion 141 must be formed to be the same as the number of coupling brackets 130, and one pair of horizontal cut portions 142 and bracket seating portions 143 are added to the left and right, respectively, and the height More will be added according to the number set in the direction.

In addition, the box wrench part 144 is formed on the bottom of the receiving body 140, and this box wrench part 144 is composed of a receiving groove 144a and a close contact part 144b as in the above-described embodiment. .
