The switching means 44 includes an eccentric disk 44a which is an eccentric disk-shaped member. The eccentric disk 44a is disposed inside the notch 43d of the body 43. Thereby, for example, in the posture of FIG. 7, the long diameter of the eccentric disk 44a is present on the right side. At this time, the main body 43 is inclined to the upper right side of the paper surface so that the locking projection 43b can be locked to the ratchet gear 40. On the other hand, when the eccentric disk 44a is rotated to have a posture as shown in FIG. 8, the long diameter of the eccentric disk 44a becomes the left side, and the eccentric disk 44a presses the inner wall of the notch 43d to change the inclination of the body 43. . In other words, at this time, the main body 43 is inclined to the upper left side of the paper surface so that the locking projection 43c can be locked to the lock gear 41.

Here, the shape of the locking teeth and the locking projections 43b of the ratchet gear 40 may be configured such that the locking projections 43b can inhibit the ratchet gear 40 from rotating in either direction, and the shape is not particularly limited. Similarly, the shape of the lock tooth and the lock projection 43c of the lock gear 41 is not particularly limited as long as the lock projection 43c can prevent the lock gear 41 from rotating in either direction.

First, the operation of the posture shown in FIG. 8 , that is, the posture in which the lock gear 41 and the lock projection 43c are locked will be described.

In the posture in which the lock gear 41 and the lock projection 43c are locked, the lock gear 41 is prohibited from being rotated in either direction. Therefore, the second sprocket 36 that is interlocked with the lock gear 41 is also prohibited from being rotated.

Further, at this time, since the locking projection 43b is not locked to the ratchet of the ratchet gear 40, the rotation of the ratchet gear 40 and the first guide sprocket 35 itself is not particularly prohibited.

In this case, as described below, the waterproof plate lifting prohibition means operates and the waterproof plate lowering prohibiting mechanism does not operate.

Next, an operation of the posture shown in FIG. 7, that is, the posture in which the ratchet gear 40 and the locking projection 43b are locked will be described. Further, the posture in which the main body 43 is locked from the locking gear 41 and the locking projection 43c (FIG. 8) to the ratchet gear 40 and the locking projection 43b (FIG. 7) can be changed by the switching means as described above. 44 proceed.

At this time, since the locking projection 43b of the main body 43 is locked to the locking tooth of the ratchet gear 40, the ratchet gear 40 cannot be rotated in either direction. Therefore, as described above, by the ratchet mechanism not shown, the first guide sprocket 35 is allowed to rotate in only one direction with respect to the ratchet gear 40, allowing the rotation of the direction shown by VIIa in Fig. 7, The rotation of the direction indicated by VIIb is prohibited due to the linkage with the ratchet gear 40.

Further, at this time, since the locking projection 43c is not locked to the locking tooth of the lock gear 41, the rotation of the lock gear 41 and the second guide sprocket 36 itself is not particularly prohibited.

In this case, as described below, the waterproof plate lowering prohibiting mechanism operates and the waterproof plate rising prohibiting means does not operate.

Regarding the relationship between the locking mechanism 39 shown here and the movement of the waterproof panel 17, It is described in detail below.

Here, the tilt direction of the current body can also be indicated by, for example, contacting a limit switch or the like to the body 43. Thereby, it is possible to judge whether or not the automatic rise of the waterproof board is stopped or the like.

Returning to Figures 1 to 4, other components will be described. The waterproof plate pressing members 45 and 46 are formed by the waterproof plate pressing member 45 and the waterproof plate pressing member 46. According to FIG. 3 and FIG. 4, the surfaces which are in contact with each other in the opposite direction are inclined. A block-like member formed in a manner. The flashing plate pressing member 45 is fixed to the frame body 30. On the other hand, the flash board pressing member 46 is fixed to the left and right side surfaces of the waterproof board 17. In the present embodiment, the flashing plate pressing member 46 also serves as the fixing member 33. As can be seen from FIG. 4, the flashing plate pressing member 45 and the flashing plate pressing member 46 are disposed such that the inclined surfaces thereof come into contact with each other in a posture in which the waterproof panel 17 is raised. Thereby, the waterproof sheet 17 can be pressed toward the passage exit side by the effect of the wedge, and the water stop performance of the waterproof board 17 can be improved.

Next, the operation of the flashing device 1 configured as described above will be described. A diagram for explaining the operation is shown in FIG. Fig. 9(a) corresponds to Fig. 3, and Fig. 9(b) corresponds to Fig. 4. That is, Fig. 9(a) shows a state in which the waterproof board 17 is located at the bottom and the water collecting bucket 16 is at the uppermost position, which is a normal posture. On the other hand, Fig. 9(b) shows a state in which the waterproof board 17 is raised to block one of the passages, and the water collecting bucket 16 is lowered, which is a posture at the time of water immersion. In FIG. 9, a large number of symbols are omitted for convenience of observation. Reference numerals refer to Figs. 3 and 4 corresponding to Fig. 9.

First, the state in which the floodboard 17 can automatically rise when the flood is equal will be described. At this time, the lock mechanism 39 is previously set to the posture shown in FIG. 7, that is, the state in which the locking projection 43b is locked to the locking tooth of the ratchet gear 40. Therefore, the waterproof plate lifting prohibition means does not operate, and the waterproof plate lowering prohibiting mechanism operates.

As shown in Fig. 3 and Fig. 9(a), the flashing device 1 is installed in a state in which the water collecting bucket 16 is disposed above the water collecting pocket 13 and the waterproofing board body 17a of the waterproof panel 17 is provided. All of them are housed in the waterproof board receiving pockets 14. In other words, since the water collecting bucket 16 and the waterproof panel 17 are controlled by the weight of the transmission mechanism 31 and are balanced by the weight thereof, the posture is usually set as shown in Fig. 3 and Fig. 9(a) as described above. The weight of the waterproof board 17 is heavier than the total weight of the water collecting bucket 16, the dewatering mechanism 23, the connection bracket 37, and the moving sprocket 38.

Further, as is clear from Fig. 3, at this time, the dewatering mechanism 23 is set to the posture shown in Fig. 5 in advance, and the drain port 16a is opened.

According to the posture shown in Figs. 3 and 9(a), since the passage is opened, the passage of a person or a car is not hindered. Further, since the grill 15b and the cover members 17b and 18 are configured so as not to have a step on the road surface as much as possible, the passage can be made more comfortable.

On the other hand, if the water level increases due to an increase in the amount of water accompanying a flood or the like, the water level in the water intake groove 15 also changes in conjunction with this. Here, at ordinary times, or because of the increase in the amount of water accompanying floods, etc. When the water level in the water intake groove 15 is lower than the road surface and lower than the water guiding member 19, the water such as rainwater flowing from the road surface through the grill 15b into the water intake groove 15 is discharged to the lower side from the drain port not shown. Drainage treatment facilities such as water pipes. Alternatively, even when the water passes over the water guiding member 19 and enters the water collecting bucket 16, the amount of water that can be sufficiently drained from the water discharge port 16a of the water collecting bucket 16 can be discharged from the water discharge port 16a and the drain mechanism 13a. That is, in this case, since the water is not stored in the water collection hopper 16, and the weight does not change, the water collection bucket 16 does not perform the lowering operation. Therefore, the postures as shown in Figs. 3 and 9(a) can be maintained.

On the other hand, as the amount of water such as a flood increases, the water level in the water intake groove 15 rises by flowing water through the grill 15b as shown by IXa in FIG. 9(a), and if the water level is higher than the water guiding member 19, Then, as shown by IXb in Fig. 9(a), the water collecting groove 15 is caused to start storing water in the water collecting bucket 16 via the guiding member 19. For such a large inflow amount of water, it is too late to drain the water from the drain port 16a, and the water collecting bucket 16 starts to store water. As a result, the floating member 26 of the dehydrating mechanism 23 floats up, and the posture shown in FIG. 6 is closed to close the drain port 16a. Moreover, if the higher water level is maintained, the water is sequentially stored in the sump 16.

Here, as described above, the water collecting bucket 16 and the waterproof board 17 are determined to be balanced by the weight of the water transfer plate 31 by the weight of the transmission mechanism 31. However, when the predetermined water is stored in the water collecting bucket 16 as described above, The weight of the water collecting bucket 16, the dewatering mechanism 23, the connecting bracket 37, and the moving sprocket 38 and the storage The weight of the water is heavier than the weight of the waterproof board 17. Thereby, as described above, if the stored water that has flowed into and stored in the water collecting bucket 16 reaches a predetermined weight, the weight of the waterproof panel 17 is exceeded, as shown by IXc in Fig. 9(a), the water collecting bucket 16 is in the water collecting. The pit 13 is lowered inside. As a result, the lowering force of the water collecting hopper 16 causes the moving sprocket 38 to rotate substantially vertically together with the water collecting bucket 16 while being rotated by the connecting bracket 37.

By this lowering, the moving sprocket 38 rotates clockwise in the viewpoint of FIGS. 3 and 9(a), and the first guide sprocket 35 and the second guide sprocket 36 rotate counterclockwise to fix The portion of the hanging chain 32 existing between the member 34 and the second guiding sprocket 36 is lengthened and pulled down to the lower side.

Thus, by pulling down the hanging chain 32, the end portion of the hanging chain 32 to which the waterproof board 17 is attached is pulled up, as shown by IXd in FIG. 9(a), the waterproof board 17 follows and rises and rises. Into the path. As a result, the water immersion in the passage is blocked by the waterproof sheet 17.

According to this type of transmission mechanism 31, since the hanging chain 32 and the sprocket wheels 35, 36, and 38 are used, the hanging chain 32 can be moved and engaged with each of the sprocket wheels 35, 36, and 38. Pulling suppresses the abrasion or sliding of the hanging chain 32 and the sprocket wheels 35, 36, 38 caused by the transmission of the lifting force to the waterproof board 17.

As described above, the lock mechanism 39 is in the posture shown in FIG. 7, that is, the locking projection 43b is locked to the locking tooth of the ratchet gear 40, and the waterproof plate lowering prohibiting mechanism is operated, and the locking projection 43c is not locked. Locking of the locking gear 41 When the basic operation of raising the waterproof plate 17 is performed in the state of the teeth, as described above, the first guide sprocket 35 rotates counterclockwise in the viewpoint of FIGS. 3 and 9(a). That is, it rotates in the direction shown by VIIa in FIG. For this type of rotation, the locking mechanism 39 allows for this rotation as described above. Therefore, the lock mechanism 39 does not hinder the rise of the waterproof board 17 and operates.

On the other hand, for example, due to some reason such as the inflow of the amount of water exceeding the amount of the imaginary rainwater, the water sump 13 is also immersed in water after the rise of the waterproof board 17 or during the rise. In this case, the inside and outside of the water collecting bucket 16 are filled with water, and the falling force when the water is only accumulated in the water collecting bucket 16 is lost. As described above, since the weight of the waterproof board 17 is originally heavier than that of the water collecting bucket 16 and the like, the rise of the waterproof board 17 cannot be maintained, and the force acts on the downward direction of the waterproof board 17.

Thus, when the waterproof panel 17 is to be lowered, the first guide sprocket 35 should be rotated clockwise in the viewpoint of FIGS. 3 and 9(a). However, the waterproofing device 1 is provided with a locking mechanism 39, and in the case of this example, the locking mechanism 39 is such that the locking projection 43b is locked to the locking tooth of the ratchet gear 40, and the waterproof plate lowering prohibiting mechanism is operated. In the state, as described above, the first guide sprocket 35 is prohibited from rotating in the clockwise direction (rotation in the direction indicated by VIIb in Fig. 7). Thereby, the rising waterproof board 17 can be prevented from falling from its position. Therefore, it is possible to prevent the undesired fall of the waterproof board 17 after the waterproof board 17 should rise and rise. That is, the accuracy of the action of the waterproof board 17 can be improved.

In the posture of the riser 17 and the ascending position of the waterproof board 17 described above, The other effects as described below are exerted by the members provided in the flashing device 1.

The sealing member 16a provided along the edge of the opening of the water collecting bucket 16 as shown in FIGS. 3 and 4 can block the gap between the inner wall surface of the water collecting pocket 13 and the water collecting bucket 16, and thus can be The water is prevented from immersing into the collecting pits 13.

Further, by the waterproof plate pressing members 20 and 21 and the waterproof plate pressing members 45 and 46, the waterproof plate 17 is pressed against the water stopping pad 22 by the effect of the wedge generated by the contact of the inclined faces. Achieve the improvement of water repellency.

Next, a state in which the waterproof panel 17 does not automatically rise even when a flood or the like is described will be described. At this time, the lock mechanism 39 is in a state shown in FIG. 8 in a state in which the lock projection 43c is locked to the lock tooth of the lock gear 41 and the waterproof plate up prohibition means is operated.

In the present example, when the water collecting bucket 16 does not store water in the normal state, as described above, the waterproof sheet 17 does not perform the operation itself to be raised, and thus the description thereof is omitted here.

On the other hand, water flows in the water intake groove 15 due to an increase in the amount of water such as a flood, thereby causing the water level in the water intake groove 15 to rise. If the water level is higher than the water guiding member 19, the waterproof plate 17 described above can be automatically In the same manner as the ascending water, the water collecting groove 15 starts to store water in the water collecting bucket 16 via the water guiding member 19. For such a large influx of water, it is too late to drain the water from the drain port 16a, and the water is stored in the water collecting bucket 16. As a result, the floating member 26 of the dehydrating mechanism 23 floats up to the posture shown in FIG. 4, and the drain port 16a is closed. Moreover, if the higher water level is maintained, then The water is sequentially stored in the water collection bucket 16.

In this case, as long as the waterproof board 17 can automatically rise, the waterproof board 17 automatically rises in the above-described manner from the posture of Figs. 3 and 9(a) to close at least a part of the passage. However, as shown in this example, when the lock member 39 is in the posture shown in FIG. 8, that is, the lock projection 43c is locked to the lock tooth of the lock gear 41, and the waterproof plate lift prohibiting means is operated, the waterproof plate is used. The rise of 17 cannot be carried out.

More specifically, when the lock member 39 is set to this posture, if the waterproof panel 17 is to be raised, the second guide sprocket 36 should be rotated counterclockwise in the viewpoint of FIG. However, the lock mechanism 39 is provided in the flashing device 1, and in the case of this example, the lock mechanism 39 is in a state in which the lock projection 43c is locked to the lock tooth of the lock gear 41, so as described above, the second is prohibited. The guide sprocket 36 is rotated counterclockwise (rotation in the direction indicated by VIIIb in Fig. 8). Thereby, the rise of the waterproof board 17 can be prohibited.

Therefore, for example, in the case of the following, the waterproof board 17 can be prevented from automatically rising, that is, the person who manages the flashing device 1 is nearby, and the waterproof board 17 does not necessarily need to be automatically raised; in the case of possible flooding, the residents In the case of evacuation for safety, the water slab has already flowed into the water slab, so that the rise of the waterproof slab is completed; the slab is raised during refuge; or the fading device is caused to flow due to some reason other than flooding such as flooding. There is a situation of water.

Of course, since it is also necessary to automatically raise the waterproof board 17, In the flashing device 1, the switching means 44 is used to switch between the case where the waterproof panel 17 can be automatically raised and the case where it does not automatically rise. At this time, in order to allow a specific manager to switch arbitrarily, it is also possible to set a lock in the switching means to restrict the rotation of the switching means.

According to the waterproof panel device 1, the rise of the waterproof panel 17 can be performed according to the user's intention, and the degree of freedom of control can be improved.

Fig. 10 and Fig. 11 are views showing a portion of the lock mechanism 139 in the flashing apparatus of the second embodiment. 10 and 11 are views similar to the viewpoints of Figs. 7 and 8. In the waterproof panel device of the present embodiment, only the lock mechanism 139 is used instead of the lock mechanism 39 provided in the flashing device of the first embodiment, and other portions are common. Therefore, the description will be made with respect to the locking mechanism 139 with reference to FIGS. 10 and 11 , and the description of the other portions will be omitted.

The lock mechanism 139 functions as a waterproof board lifting prohibition means and a waterproof board lowering prohibiting mechanism, and includes a first brake drum 140, a second brake drum 141, and a brake lever 142. The lock mechanism 139 is provided with a ratchet mechanism, and constitutes a so-called brake that prohibits rotation by friction, and allows the first guide sprocket 35 to rotate in one direction, and prohibits the rotation in the opposite direction. Further, the lock mechanism 139 has a locking function that can restrict the rotation of the second guide sprocket 36 and prohibit the rise of the waterproof plate 17. It is explained below.

The first brake drum 140 is a disk-shaped member and is formed to be prohibited by friction of the outer peripheral surface thereof with the first brake pad 143b of the brake lever 142 described below. The rotation of a brake drum 140. The material used for the first brake drum 140 may be a known material that can function as a brake drum by utilizing the relationship with the brake pad.

10 and FIG. 11, the first brake drum 140 is disposed coaxially with the first guide sprocket 35, and the first brake drum 140 and the first guide sprocket 35 are configured to be oriented toward the first guide sprocket 35. When the direction of the direction of the rotation indicated by Xb in Fig. 10 is interlocked, the first guide sprocket 35 is rotatable when the first guide sprocket 35 is rotated in the direction indicated by Xa in Fig. 10 . That is, in the present embodiment, the first guide sprocket 35 and the first brake drum 140 are superposed on each other via a ratchet mechanism (not shown). The ratchet mechanism used for this is not particularly limited, and may be a known ratchet mechanism.

The second brake drum 141 is also a disc-shaped member and is formed to prohibit the rotation of the second brake drum 141 by friction of the outer peripheral surface thereof with the second brake piece 143c of the brake lever 142 described below. The material used for the second brake drum 141 may be a known material that can function as a brake drum by utilizing the relationship with the brake pad.

10 and 11, the second brake drum 141 is disposed coaxially with the second guide sprocket 36, and the second brake drum 141 and the second guide sprocket 36 are fixed in a continuous manner.

The brake lever 142 is disposed to surround the first brake drum 140 and the second brake drum 141 from the lower side and the side surface, and includes a main body 143 and a switching means 144.

10 and 11, the main body 143 has a substantially trapezoidal lower end and a substantially trapezoidal structure which is longer than the bottom of the lower bottom, and has a rectangular notch 143d on the lower bottom side. Further, at the end of the upper end of the body 143, a first brake pad 143b is disposed at an end closer to the first brake drum 140, and a second brake pad is disposed at an end closer to the second brake drum 141. 143c. Further, the main body 143 is movable in the left-right direction of the paper surface of Figs. 10 and 11 .

The first brake pad 143b and the second brake pad 143c are arc-shaped members and are disposed to surround one of the outer circumferences of the first brake drum 140 and the second brake drum 141. As described above, the first brake pad 143b and the second brake pad 143c are configured to function as a brake pad by the relationship between the first brake drum 140 and the second brake drum 141.

Further, one end of the first brake piece 143b and the second brake piece 143c is rotatably fixed to the main body 143 as described above, and the other end is rotatably fixed to the frame body 30.

The switching means 144 is a member having a function of switching the posture shown in FIG. 10 of the main body 143 and the posture shown in FIG. The switching means 144 includes an eccentric disk 144a which is an eccentric disk-shaped member. The eccentric disk 144a is disposed inside the notch 143d of the body 143. Thus, for example, in the posture of FIG. 10, the long diameter of the eccentric disk 144a exists on the left side of the paper surface, and at this time, the first brake pad 143b of the body 143 is pressed against the first brake drum 140. On the other hand, when the eccentric disk 144a is rotated to have a posture as shown in FIG. 11, the long diameter of the eccentric disk 144a becomes the right side of the paper surface, and the eccentric disk 144a presses the notch 143d. The inner wall allows the body 143 to move. That is, at this time, as shown in FIG. 11, the second brake pad 143c of the body 143 is pressed against the second brake drum 141.

First, an operation of the posture shown in FIG. 10, that is, the posture in which the first brake pad 143b is pressed against the first brake drum 140 will be described. At this time, the first brake drum 140 cannot be rotated in either direction by the effect of braking. Therefore, as described above, the first guide sprocket 35 is allowed to rotate in only one direction with respect to the first brake drum 140 by a ratchet mechanism (not shown), allowing the rotation of the direction shown by Xa in Fig. 10 The rotation in the direction indicated by Xb is prohibited by the linkage with the first brake drum 140.

In this case, as described in the above description, the rotation of the first guide sprocket 35 is allowed in the direction in which the waterproof panel 17 rises, and the rotation of the first guide sprocket 35 is prohibited in the direction in which the waterproof panel 17 is lowered. move. That is, the same effects as those of the lock mechanism 39 provided in the flashing device 1 of the first embodiment are exhibited.

Further, at this time, since the second brake pad 143c is not in contact with the second brake drum 141, the rotation of both is not particularly prohibited.

Next, an operation of the posture shown in FIG. 11 , that is, the posture in which the second brake pad 143c is pressed against the second brake drum 141 will be described. The change of the body 143 from the posture in which the first brake pad 143b is pressed against the first brake drum 140 (FIG. 10) to the second brake pad 143c against the second brake drum 141 (FIG. 11) can be changed as described above. The switching means 144 is performed.

In the posture shown in Fig. 11, the second brake drum 141 is prohibited from being rotated in either direction. Therefore, the second sprocket 36 that is interlocked with the second brake drum 141 is also the same The plot is prohibited from spinning.

Further, at this time, since the first brake pad 143b is not in contact with the first brake drum 140, the rotation of the two is not particularly prohibited.

In this case, the rise and fall of the waterproof board 17 are prohibited. For example, in the case where a person who manages the flashing device is in the vicinity or the like, the waterproof plate 17 does not necessarily need to be automatically raised, and it is desirable to prohibit the use of the waterproof plate 17 in advance when it is automatically raised. In this case, when the person who manages the waterproof panel device leaves the position and there is no one, the switching means 144 is set to the posture shown in FIG. 10, and the waterproof panel 17 can be automatically raised.

In each of the embodiments described above, an example in which the locking function is provided on the side of the second guide sprocket 36 has been described. However, the present invention is not limited thereto, and may be configured to have a locking function on the side of the first guide sprocket 35.
