Description

  The present invention relates to measures against flood damage. Entrances and passages of various buildings such as subways, underground facilities, and districts where water may flow in when water is flooded due to heavy rain, typhoons, tsunami, or other causes. It is related to a water stop door system that prevents water from flowing into the interior without being operated by human power without being operated by a natural operation and operates smoothly even under the influence of water pressure.

  In addition, there are many places where there are no facilities for inflow of water to underground facilities and low land in urban areas and urban areas in response to torrential rains and typhoons due to abnormal weather in recent years. The victims are out.

Also, in urban areas, there are facilities that are difficult to evacuate in the event of floods, such as heavy rains and river flooding, even in densely populated areas with many underground facilities inland.

  In addition, in the case of a water stop door that uses electric power or power, it may not be able to operate in the event of a power failure, and it may not be able to demonstrate its full capacity. It is said that emergency shelters and shelters for evacuation need to be constructed, assuming that there are cases where human lives may be at risk and evacuation may be difficult.

  In addition, there are many facilities that are difficult to relocate in areas where flood damage is expected, and some people are taking preventive measures on a daily basis. There are few things that can be said to be sufficient.

  Several systems have been proposed to stop water using either buoyancy or underground storage. (Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4)

  In addition, in the case of conventional equipment, considering the entry and exit of people and vehicles during normal use, it is necessary to ensure the strength of the water stop door, there are weight restrictions on the material and structure of the water stop door, There are various problems such as requiring operation by humans, difficulty in operation in the event of a power failure, requiring a certain amount of time for closing, and being affected by water pressure.

  With regard to the mode for carrying out the present invention, an embodiment of 8 examples and a setting execution method having the same basic structure will be described in detail with reference to the drawings.

Example 1 will be described in detail with reference to FIGS. 1a, 1b, 1c, and 1d.
1a and 1b is stored in the water tank C so that the upper surface of the step portion 3 installed at the upper part of the water stop door main body 1 is the same height as the ground surface E. The drainage hole D normally drains, but the drainage capacity exceeds the drainage capacity, the water level in the water tank C rises, and the water stop door body by the upper float 5 at the water level above the floating start position 1F1 in either one of FIGS. No. 1 protects the inside of the facility A from entering the water by rising and lowering with the water level while stopping the water, and when the water level rising speed is slow or the rising water level is low or does not need to be completely closed It is used on the assumption that evacuees go in and out during installation and water level rise.

  In addition, regarding the normal operation of the water stop door body 1 of FIGS. 1a and 1c even when subjected to water pressure, the operation of the water stop door body 1 rising and lowering by the buoyancy of the upper float 5 and the main guide roller 7a7b in the lateral direction When the guide roller 8a8b rolls between the inclined left and right guide pillars 2 formed along the facility side wall B in either of FIG. 1a and FIG. 1c, the force with which the water pressure presses the water stop door body 1 is the main guide. The rotational force of the roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 is converted into rotational friction and most of it is digested, so that the force for pressing the waterstop door body 1 by water pressure is greatly reduced, and the waterstop door body 1 Relatively small frictional resistance generated with the seal member 4a during the upward / downward movement of the cylinder remains as the main frictional resistance, minimizing the influence of water pressure as a whole system With the structure, the auxiliary roller 9 is distorted by the water pressure and the water stop door body 1 is excessively closely contacted with the seal member 4a in FIG. 1b to prevent damage to each part due to the water pressure of the water stop door body 1 being distorted. A structure in which the auxiliary roller 9 has a wide surface in contact with the water stop door main body 1 so as not to prevent the rising and lowering movement of the water stop door main body 1 due to an increase in frictional resistance generated between the seal member 4a and the seal member 4a. Install at the required location.

  Further, the stepped portion 3 installed on the upper part of the water stop door main body 1 with the structure in which the water stop door main body 1 is also inclined and moved up and down by the inclined guide pillar 2 of FIGS. 1 a and 1 c is an attachment portion of the upper float 5. By acting as a resistance plate, the force of the water flow 1J in FIG. 1c received by the front surface of the water stop door body 1 acts in the direction of the water flow 2K due to the inclination, and the step part 3 receives the resistance of the water flow 2K to stop the water. In order to push up the door body 1, the power of the water flow 2K that raises the water stop door body 1 more stably in synergy with the upper float 5 and raises the water stop door body 1 depends on the magnitude of the force of the water flow 1J. Accordingly, the reaction speed and height of the still water main body 1 with respect to the rising and lowering speed of the water surface 1Ha are always kept optimal, and the water stopping door main body 1 is raised to the stopper 22 at the highest rising position. Can prevent water levels below part 3 and stop The door body 1 and the step part 3 have a structure that can withstand the weight of a vehicle or a person who passes through the facility or the person without any trouble during normal use of the facility. 1b is supported by the lower stopper 21 so that the lower float 6 is not damaged.

  Also, by combining the effects of 0023 and 0024, most of the resistance due to water pressure is digested, and the relatively low frictional resistance generated in the area where the water stop door body 1 and the seal member 4a in FIGS. The resistance of the water stop door body 1 due to water pressure is prevented from increasing, and the weight of the water stop door body 1 is supported by the buoyancy of the lower float 6 so that the water stop door body 1 in the standby state is It floats easily with the buoyancy of the upper float 5 at the water level above the floating start position 1F1.

  Moreover, if the water in the water tank C of FIG. 1c and FIG. 1d is drained by the drain hole D, external power, etc., the water stop door main body 1 will be stored, descending with the fall of the water surface 1Ha.

  In addition, in the first embodiment, the buoyancy of the upper float 5 and the lower float 6 in FIGS. 1a, 1b, 1c, and 1d is set so that the water stop door body 1 and the associated members are lower than the floating start position F1. In order to support the weight of the stationary door main body 1 in the standby state and the associated members by the lower float 6 below the maximum buoyancy in which the sum of the weight in the water and the weight above the floating start position F1 is less than the equivalent The buoyancy of the upper float 5 is set so that the buoyancy of the upper float 5 exceeds the remaining weight, the buoyancy exceeding the frictional resistance of the waterproof door body 1 and the seal member 4a, and the safety margin assuming the disaster situation and the usage environment of the facility. The buoyancy for raising the water door body 1 is set.

Example 2 will be described in detail with reference to FIGS. 2a, 2b and 2c.
2a and 2b are stored in the water tank C so that the upper surface of the step portion 3 installed at the upper part of the water stop door body 1 is the same height as the ground surface E. The drainage hole D normally drains the water, but the water level in the tank C rises above the drainage capacity, and the water stop door body by the lower float 6 at the water level that exceeds the floating start position 2F2 in either FIG. 2a or 2b. Assuming that a large amount of water is rushed in a short time because the water level rises quickly and the inside of the facility A is protected from flooding by raising the water tank 1 and raising it completely before the tank C is full. The water stop door body 1 that is used in a facility that does not need to be closed and that is in a standby state for floating easily rises by the buoyancy of the lower float 6 at a water level above the floating start position 2F2.

  Further, when water flows into the water tank C of FIG. 2c, the water stop door body 1 rises according to the height of the water level Hb of the water tank C, so that the guide column 2 and the water stop door body 1 of FIG. The purpose of this is to stably bring the main guide roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 into contact with the guide column 2 to suppress the play when the waterstop door body 1 floats, and the seal member 4a and the waterstop door. Step 3 in FIG. 2c when the main body 1 is always in close contact, the guide column 2 is more stably and smoothly operated than when it is vertically formed, and a large amount of water is rushed more quickly than expected. Even if it receives a water flow that exceeds the floating start position 2F2, it is pushed up in the upward direction in synergy with the upper float 5, preventing the resistance from increasing due to the water pressure received by the water stop door body 1, and the water stop door body 1 rising highest Position stopper The water stop door body 1 and the step portion 3 can be prevented from reaching the water level below the step portion 3 and the weight of the vehicle and the person passing through the vehicle and the person without any trouble during normal use of the facility. The waterproof door body 1 is supported by the lower stopper 21 in FIGS. 2a and 2b so that the lower float 6 is not damaged during storage, and the auxiliary roller 9 is stopped by water pressure. The main body 1 is distorted and excessively closely contacts with the seal member 4a in FIG. 2b to prevent breakage of each part due to distortion of the water stop door main body 1 due to water pressure, and the frictional resistance generated between the water stop door main body 1 and the seal member 4a. The auxiliary roller 9 is installed at a required location with a structure having a wide width in contact with the water stop door main body 1 so as not to hinder the upward movement of the water stop door main body 1 due to the increase of the water.

  Moreover, if the water in the water tank C of FIG. 2c is drained by the drain hole D, external power, etc., the water stop main body 1 will be stored, descending with the fall of the water surface 2Hb.

  Moreover, the setting of the buoyancy of the upper float 5 and the lower float 6 in FIGS. 2a, 2b, and 2c in Example 2 is equivalent to the total weight of the total weight of the water blocking door body 1 with all the attached members attached. Buoyancy lifts the water stop door body 1 with a safety margin that assumes a disaster situation as surplus buoyancy and surplus buoyancy due to frictional resistance generated between the water stop door body 1 and the sealing member 4a when the water stop door body 1 moves up and down. The sum total of the buoyancy is set, and the upper float 5 is set to a buoyancy equivalent to the lower float 6 as a spare float or is not used.

Example 3 will be described in detail with reference to FIGS. 3a, 3b, 3c, and 3d.
3a and 3b is stored in the water tank C so that the upper surface of the step part 3 installed on the upper part of the water stop door body 1 is the same height as the ground surface E. Although the water is normally drained by the drainage hole D, the water level in the water tank C exceeds the drainage capacity and rises to the floating start position 1F1 or higher in any one of FIGS. 3a and 3b. 1 rises and falls with the water level while stopping the water, and the water level 3Hc in FIGS. 3c and 3d exceeding the highest part B1 of the facility entrance in FIG. Used when.

  Further, regarding the normal operation of the water stop door body 1 shown in FIGS. 3c and 3d even when subjected to water pressure, the operation of the water stop door body 1 ascending and descending due to the buoyancy of the upper float 5 is compared with the main guide roller 7a7b. When the guide roller 8a8b rolls between the right and left guide pillars 2 formed along the facility side wall B in either of FIGS. 3a and 3c, the force that the water pressure presses the water stop door body 1 is the main guide. The rotational force of the roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 is converted into rotational friction and most of it is digested, so that the force for pressing the waterstop door body 1 by water pressure is greatly reduced, and the waterstop door body 1 With a structure in which a relatively small frictional resistance with the seal member 4b during the upward / downward movement remains as a main frictional resistance, and the influence of water pressure is minimized as a whole system, The auxiliary roller 9 is distorted by the water pressure, and the water stop door body 1 is distorted. The auxiliary roller 9 is in close contact with the seal member 4b of FIG. The auxiliary roller 9 is installed in order to prevent the rising and lowering movement of the water stop door body 1 due to an increase in frictional resistance generated between the seal members 4b, and the auxiliary roller 9 is required to have a structure with a wide width in contact with the water stop door body 1. Install in the place.

  Further, the stepped portion 3 installed at the upper part of the water stop door body 1 is structured so that the water stop door body 1 is also inclined and moved up and down by the inclined guide pillar 2 of FIGS. By acting as a resistance plate, the water flow 1J in FIG. 3c received by the water stop main body 1 acts in the direction of the water flow 2K due to the inclination, and the step part 3 receives the resistance of the water flow 2K and the water stop door main body. In order to push up 1, the water stop door body 1 is raised more stably in synergy with the upper float 5, and the force of the water flow 2K that raises the water stop door body 1 is increased according to the magnitude of the force of the water flow 1J. Therefore, the reaction speed and height of the water stop door body 1 with respect to the rising and lowering speed of the water surface 1Ha are always kept optimal, and the water stop door body 1 rises to the upper stopper 22 which is the highest rise position. By the water stop main body 1 and the sealing member 4b of 3c By sealing up to the highest part B1 of the entrance and completely stopping the water, the water level exceeding the limit of the rising height of the water stopping door body 1 in FIGS. Even in the situation, the ingress of water can be prevented and the facility entrance A can be protected by sealing the facility entrance and shutting off completely. The waterproof door body 1 is supported by the lower stopper 21 shown in FIGS. 3a and 3b so that the lower float 6 is not damaged during storage. It has become.

  Also, by combining the effects of 0033 and 0034, most of the resistance due to water pressure is digested, and a relatively light frictional resistance generated in the area where the water stop door body 1 and the seal member 4b in FIGS. The resistance of the water stop door body 1 due to water pressure is prevented from increasing, and the weight of the water stop door body 1 is supported by the buoyancy of the lower float 6 so that the water stop door body 1 in the standby state is It floats easily with the buoyancy of the upper float 5 at the water level above the floating start position 1F1.

  Moreover, if the water in the water tank C of FIG. 3c and FIG. 3d is drained with the drainage hole D, external power, etc., the water stop door main body 1 will be stored, descending with the fall of the water surface 1Ha.

  Further, in the third embodiment, the buoyancy of the upper float 5 and the lower float 6 in FIGS. 3a, 3b, 3c, and 3d is set so that the water stop door body 1 and the associated members are located below the floating start position 1F1. In order to support the weight of the stationary door main body 1 and the associated members by the lower float 6 below the maximum buoyancy in which the sum of the weight in the water and the weight above the levitation start position 1F1 is less than or equal to the equivalent. The buoyancy of the upper float 5 is set so that the buoyancy of the upper float 5 exceeds the remaining weight, the buoyancy exceeding the frictional resistance of the waterproof door body 1 and the seal member 4b, and a safety margin that assumes the disaster situation and the usage environment of the facility. The buoyancy for raising the water door body 1 is set.

Example 4 will be described in detail with reference to FIGS. 4a, 4b, and 4c.
4a and 4b are stored in the water tank C so that the upper surface of the step part 3 installed on the upper part of the water stop body 1 is the same height as the ground surface E. The drainage hole D normally drains, but the water level in the water tank C rises above the drainage capacity and rises above the rising start position 2F2, and the waterstop door body 1 is lifted by the lower float 6 so that the water tank C By completely closing the facility A before it becomes full, the inside of the facility A is protected from water damage. By quickly closing the facility, the water level rises quickly, and a large amount of water comes in a short time. In response to the above, the still water main body 1 in the standby state is easily floated by the buoyancy of the lower float 6 at the water level above the floating start position 2F2.

  Further, when water flows into the water tank C of FIG. 4c, the water stop door body 1 rises in accordance with the height of the water level Hb of the water tank C. Therefore, the guide pillar 2 and the water stop door body of FIGS. 4a and 4c. The purpose of inclining 1 is to stably bring the guide roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 into contact with the guide pillar 2 to suppress the play when the waterstop door body 1 floats, and to seal the seal member 4b and the waterstop. Step 3 in FIG. 4c when the door body 1 is always kept in close contact with the guide column 2 and the guide column 2 is more stable and smoothly operated, and when a large amount of water is rushing faster than expected. In response to the water flow exceeding the rising start position 2F2, it is pushed up in the ascending direction in synergy with the upper float 5 to prevent the resistance from increasing due to the water pressure received by the water stopping door body 1 and the highest rising position of the water stopping door body 1. Upper stopper to be As the water level 3Hc exceeds the limit of the rising height of the water stop door body 1, the water stop door body 1 and the sealing member 4b are sealed up to the highest part B1 of the facility entrance and completely stopped. Even in situations where the water level exceeds the roof 19 of the facility, water can be prevented from entering, and the facility entrance A can be protected by sealing the facility entrance and completely shutting off the water. It is structured to be able to withstand the weight of a vehicle or a person who passes through the vehicle or person without any trouble during normal use, and the water stop door body 1 is supported by the lower stopper 21 in FIGS. 4a and 4b during storage. The lower float 6 is not damaged, and the auxiliary roller 9 is distorted by the water pressure due to the water pressure, and the sealing door body 1 is excessively closely attached to the seal member 4b of FIG. Preventing breakage and waterstop body 1 The auxiliary roller 9 is installed so as not to hinder the upward movement of the water stop door body 1 due to an increase in frictional resistance generated between the seal members 4b, and the auxiliary roller 9 has a structure with a wide width in contact with the water stop door body 1 and a necessary portion. Install in.

  Moreover, if the water in the water tank C of FIG. 4c is drained by the drainage hole D, external power, etc., the water stop main body 1 will be stored, descending with the fall of the water surface 2Hb.

  Moreover, the setting of the buoyancy of the upper float 5 and the lower float 6 in FIGS. 4a, 4b, and 4c in Example 4 is equivalent to the total weight of the total weight of the water blocking door body 1 with all the attached members attached. The water stop door body 1 is secured with a buoyancy and a safety margin that assumes a disaster situation as surplus buoyancy due to the loss of buoyancy due to frictional resistance generated between the water stop door body 1 and the seal member 4b when the water stop door body 1 moves up and down The sum total of the buoyancy is set, and the upper float 5 is set to a buoyancy equivalent to the lower float 6 as a spare float or is not used.

Example 5 will be described in detail with reference to FIGS. 5a, 5b, 5c, and 5d.
5a and 5b is stored in the water tank C so that the upper surface of the step part 3 installed on the upper part of the water stop door body 1 is at the same height as the ground surface E. The drainage hole D normally drains, but the drainage capacity exceeds the drainage capacity, the water level in the water tank C rises, and the water stop door body 1 rises with the water level while the water is stopped by the upper float 5 at the water level above the floating start position 1F1. By descending, the inside of the facility A is protected from water damage, and a heavy door is required, and if the water level rise speed is slow, the rising water level is low, or the facility is not required to be completely closed, the evacuees are being installed It is used assuming that etc. come in and out.

  Further, regarding the normal operation of the water stop door body 1 shown in FIGS. 5c and 5d even when subjected to water pressure, the operation of the water stop door body 1 rising and lowering due to the buoyancy of the upper float 5 and the main guide roller 7a7b in the lateral direction. When the guide roller 8a8b rolls between the inclined right and left guide pillars 2 formed along the facility side wall B in either of FIG. 5a and FIG. 5c, the force with which the water pressure presses the water stop door body 1 is the main guide. The rotational force of the roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 is converted into rotational friction and most of it is digested, so that the force for pressing the waterstop door body 1 by water pressure is greatly reduced, and the waterstop door body 1 With a structure in which a relatively small frictional resistance with the seal member 4a during the ascending / descending movement remains as a main frictional resistance, and the influence of water pressure is minimized as a whole system, The auxiliary roller 9 is distorted by the water pressure and the water stop door main body 1 is distorted. The auxiliary roller 9 is in close contact with the seal member 4a of FIG. The auxiliary roller 9 is installed in order to prevent the rising and lowering movement of the water stop door body 1 due to an increase in frictional resistance generated between the seal members 4a, and the auxiliary roller 9 is required to have a structure with a wide width in contact with the water stop door body 1. Install in the place.

  5a and 5c is a structure in which the waterstop door body 1 is also inclined and moved up and down by the inclined guide pillar 2 in FIG. By acting as a resistance plate, the water flow 1J in FIG. 5c received by the water stop main body 1 acts in the direction of the water flow 2K due to the inclination, and the step part 3 receives the resistance of the water flow 2K and the water stop door main body. In order to push up 1, the water stop door body 1 is raised more stably in synergy with the upper float 5, and the water stop door body 1 rises to the stopper 22 at the highest rise position and prevents the water level below the step portion 3. Since the force of the water flow 2K that raises the water stop main body 1 increases according to the magnitude of the force of the water flow 1J, the reaction speed of the water stop main body 1 is higher than the speed of the water surface 1Ha rising and falling. The water stop door itself is always optimal The step portion 3 has a structure that can withstand the weight of a vehicle or a person who passes through the facility or the person without trouble during normal use of the facility. The lower float 21 is supported so that the lower float 6 is not damaged.

  Also, by combining the effects of 0043 and 0044, most of the resistance due to water pressure is digested, and the relatively light frictional resistance generated in the area where the water stop door body 1 and the seal member 4a in FIGS. Therefore, it is possible to prevent an increase in resistance that hinders the movement of the still water door main body 1 due to water pressure. By supporting the weight of the door main body 1, the water stop door main body 1 easily floats by the buoyancy of the upper float 5 at a water level higher than the rising start position 1F1.

  In the counterweight 15 of FIGS. 5a, 5b, 5c, and 5d, the wire 13 is attached to the waterproof door body 1 by using the wire attachment member 14, and is corrected vertically through the auxiliary pulley 12 for correcting the wire angle.

The counterweight 15 compensates for the lack of buoyancy of the lower float 6 or the inability to use the lower float 6 so that the waterstop body 1 can be lifted reliably and smoothly. And when using high-strength doors, which are necessary when installing in large facilities or assuming considerable flood damage It is an object corresponding to the case where and lower float 6 if the buoyancy of the amount increase and lower float 6 is insufficient is not available.

  Moreover, if the water in the water tank C of FIG. 5c and FIG. 5d is drained with the drainage hole D, external power, etc., the water stop door main body 1 will be stored, descending with the fall of the water surface 1Ha.

  5a, 5b, 5c and 5d in the fifth embodiment, the buoyancy of the upper float 5 and the lower float 6 and the weight of the counterweight 15 are set so that the buoyancy of the lower float 6 is The maximum buoyancy that is less than the total of the weight of the upper float 5 with the attached members attached below the levitation start position 1F1 and the weight of the upper part of the levitation start position 1F1 below the equivalent, The weight equivalent to the buoyancy required by the counterweight 15 is equally allocated to the left and right for the insufficient buoyancy, or the lower float is set to compensate for the insufficient buoyancy by the weight of the counterweight 15 as one of the weights. The buoyancy and weight necessary to support the weight of the stationary door body 1 and the associated members with the buoyancy of 6 and the weight of the counterweight 15 The buoyancy of the upper float 5 is set in consideration of the remaining weight and the loss of buoyancy due to the frictional resistance between the water blocking door main body 1 and the seal member 4a, and the buoyancy, the damage situation, and the usage environment of the facility exceeding it are assumed. The surplus buoyancy is set as a safety margin, and the buoyancy for floating the waterstop door body 1 is set, and the buoyancy of the lower float 6 when the lower float 6 is not used is added to the weight of the counterweight 15. .

Example 6 will be described in detail with reference to FIGS. 6a, 6b and 6c.
6a and 6b is stored in the water tank C so that the upper surface of the step portion 3 installed at the upper part of the water stop door body 1 is the same height as the ground surface E. The drainage hole D normally drains, but the water level in the water tank C rises above the drainage capacity and rises above the rising start position 2F2, and the waterstop door body 1 is lifted by the lower float 6 so that the water tank C By completely ascending before the water is full, the inside of the facility A is protected from water damage, and a heavy door is required and the water level rises fast so that a large amount of water can be pushed in for a short time. Used for facilities that do not require

Further, when water flows into the water tank C of FIG. 6c, the water stop door main body 1 rises according to the height of the water level Hb of the water tank C. Therefore, the guide pillar 2 and the water stop door main body of FIG. 6a and FIG. The purpose of inclining 1 is to stably bring the main guide roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 into contact with the guide pillar 2 to suppress the play when the waterstop door body 1 is lifted and to stop the seal member 4a. The step shown in FIG. 6c is when the water door main body 1 is always kept in close contact with the guide pillar 2 and the guide column 2 is made to operate more stably and smoothly, and when a large amount of water is rushing faster than expected. 3 receives the water flow exceeding the rising start position 2F2 and pushes it upward in synergy with the upper float 5 to prevent the increase in resistance due to the water pressure received by the waterstop body 1, and the waterstop body 1 rises the highest Position stopper The water stop door body 1 and the step portion 3 can be prevented from reaching the water level below the step portion 3 and the weight of the vehicle and the person passing through the vehicle and the person without any trouble during normal use of the facility. The waterproof door body 1 is supported by the lower stopper 21 shown in FIGS. 6A and 6B so that the lower float 6 is not damaged during storage, and the auxiliary roller 9 is stopped by water pressure. The main body 1 is distorted and excessively tightly contacts with the seal member 4a in FIG. 6b to prevent breakage of each part due to the distortion of the water stop main body 1 due to water pressure, and the frictional resistance generated between the water stop door main body 1 and the seal member 4a. The auxiliary roller 9 is installed at a required location with a structure having a wide width in contact with the water stop door main body 1 so as not to hinder the upward movement of the water stop door main body 1 due to the increase of the water.

  6a, 6b, and 6c, the wire 13 is attached to the waterproof door body 1 by using the wire attachment member 14, and is corrected vertically through the auxiliary pulley 12 for correcting the wire angle. The counterweight 15 is suspended in the counterweight guide pillar 16 through the upper end of the counterweight guide pillar 16 so that water does not enter, and is waterproofed by the waterproof cover 17, along the guide pillar 2 in FIG. The counterweight 15 is installed symmetrically or either, and the counterweight 15 compensates for the lack of buoyancy of the lower float 6 to assist the stationary door body 1 to rise reliably and smoothly, and can be installed in a large facility. The main purpose is to handle the heavy weight when using high-strength doors, which are necessary when large floods are also expected. Eight 15 easily floats by buoyancy of the lower float 6 in the water level of the floating starting position 2F2 or more can support the weight of the member associated with the water stop door body 1 of the flying standby state.

  Moreover, if the water in the water tank C of FIG. 6c is drained by the drainage hole D, external power, etc., the water stop main body 1 will be stored, descending with the fall of the water surface 2Hb.

  In addition, the buoyancy of the upper float 5 and the lower float 6 and the weight of the counterweight 15 in FIGS. 6a, 6b, and 6c in Example 6 are set to the total weight of the water stop main body 1 with all the attached members attached. The maximum weight that is less than or equal to the total weight is equally distributed to the left and right as the weight of the counterweight 15, or set as either one, and the water stop door with all the attachment members in the standby state depending on the weight of the counterweight 15 For the purpose of supporting the entire weight of the main body 1, the buoyancy of the lower float 6 is a water stop with all the attached frictional resistance and the attached members attached to the seal member 4 a when the water stop door main body 1 is raised and lowered. The buoyancy required to ascend the water-stopping door body 1 that secures a safety margin assuming a disaster situation as the buoyancy necessary for surfacing the door body 1 and surplus buoyancy. Set as 6 buoyancy, or the upper float 5 is set to equal buoyancy and lower float 6 as an alternate float, and either not used.

Example 7 will be described in detail with reference to FIGS. 7a, 7b, 7c, and 7d.
7a and 7b is stored in the water tank C so that the upper surface of the step part 3 installed on the upper part of the water stop main body 1 is the same height as the ground surface E. The drainage hole D normally drains, but the drainage capacity exceeds the drainage capacity, the water level in the water tank C rises, and the water stop door body 1 rises with the water level while the water is stopped by the upper float 5 at the water level above the floating start position 1F1. It is used when the inside A of the facility is protected from water damage by descending, a heavy door is required, and submergence or a considerable rise in water level is assumed.

  In addition, regarding the normal operation of the water stop door body 1 shown in FIGS. 7c and 7d even when subjected to water pressure, the operation of the water stop door body 1 rising and lowering by the buoyancy of the upper float 5 and the main guide roller 7a7b in the lateral direction When the guide roller 8a8b rolls between the inclined right and left guide pillars 2 formed along the facility side wall B in either FIG. 7a or FIG. 7c, the force that the water pressure presses the water stop door body 1 is the main guide. The rotational force of the roller 7a7b, the lateral guide roller 8a8b, and the auxiliary roller 9 is converted into rotational friction and most of it is digested, so that the force for pressing the waterstop door body 1 by water pressure is greatly reduced, and the waterstop door body 1 With a structure in which a relatively small frictional resistance with the seal member 4b during the upward / downward movement remains as a main frictional resistance, and the influence of water pressure is minimized as a whole system, The auxiliary roller 9 prevents the water stop door main body 1 from being in close contact with the strain seal member 4b due to water pressure to prevent breakage of each part due to distortion of the water stop door main body 1 due to water pressure, and between the water stop door main body 1 and the seal member 4b.

In order to push up the door body 1, the power of the water flow 2K that raises the water stop door body 1 more stably in synergy with the upper float 5 and raises the water stop door body 1 depends on the magnitude of the force of the water flow 1J. Therefore, the reaction speed and height of the still water main body 1 with respect to the rising and lowering speed of the water surface 1Ha are always maintained optimally, and the water rises to the upper stopper 22 which is the highest rising position of the water stopping door main body 1. , Applied by the waterproof door body 1 and the seal member 4b By sealing up to the highest part B1 of the entrance and completely stopping the water, the situation of the high water level exceeding the facility roof part 19 like the water level 3Hc exceeding the limit of the rising height of the water stopping door body 1 in FIGS. 7c and 7d However, the inside A of the facility can be protected, and the water blocking door main body 1 and the step portion 3 have a structure that can withstand the weight of the vehicle and the person who passes through the facility and the person without any obstacles during normal use of the facility. The waterstop door body 1 is supported by the lower stopper 21 in FIGS. 7a and 7b so that the lower float 6 is not damaged during storage.

The counterweight 15 compensates for the lack of buoyancy of the lower float 6 or the inability to use the lower float 6 so that the waterstop body 1 can be lifted reliably and smoothly. And when using high-strength doors, which are necessary when installing in large facilities or assuming considerable flood damage It is an object corresponding to the case where and lower float 6 if the buoyancy of the amount increase and lower float 6 is insufficient is not available.

The buoyancy and weight required to support the weight of the waterstop door body 1 in the ascending standby state and the associated members by the buoyancy of the float 6 and the weight of the counterweight 15 The amount of buoyancy of the upper float 5 is set in consideration of the remaining weight and the loss of buoyancy due to the frictional resistance between the water blocking door body 1 and the seal member 4b. Set the buoyancy for levitating the waterstop door body 1 with the assumed surplus buoyancy as a safety margin, and add the buoyancy of the lower float 6 to the weight of the counterweight 15 when the lower float 6 is not used. To do.

It is installed in areas where flood damage is expected, such as dikes, entrances and passages of various buildings, etc., and it can protect the facilities, assets, and lives inside or inside, and has a small number of parts and a simple structure. Therefore, regular inspection is easy, the maintenance cost after installation is low, and the service life is long, so it is a cost-effective system.
Also, on a daily basis, in facilities where many people go in and out, an operation setting in which the water stop door rises as the water level rises is suitable, and it can be used for subway entrances and underground facilities.
In addition, the water stop doors that use counterweights are not limited in weight, so the necessary strength can be secured sufficiently, and the full width and height of the water stop doors can be freely designed. It can be used to protect internal facilities and human life with a system that is installed at the entrance and exit of a factory warehouse, taking into account flooding.
Moreover, since it operates only when it is submerged without impeding the passage of people and vehicles, it can be used for buildings and passages in various facilities and factories.
In addition, by installing the float-type water stop doors of the present invention and performing water-proof construction assuming submergence in coastal lines, near rivers, low-rise public facilities, public halls, and factory warehouses, in the event of a tsunami or flood It can be used as an emergency shelter for protecting internal equipment and assets.
In addition, since many facilities that are normally used can be used, there is no need to construct a separate shelter, and many existing facilities are targeted for installation, so it is cost-effective and has a relatively short construction period. It is possible to install difficult facilities in many places in a short time.
In addition, since the system can perform a plurality of setting methods with the same basic design, it can be standardized to some extent as a product, so that the production cost can be kept low.
In addition, since operation is not required by humans, the lives of workers can be protected and evacuation activities and evacuation guidance activities can be carried out in a concentrated manner. Because evacuation activities can be performed, it can be understood that the students who can use it as a waterproof system with the float type water stop door of the present invention are large.
