Description

  The present invention relates to a catchment for collecting rainwater and the like, and more particularly to a catchment for a catchment for smoothly maintaining the inflow of water into the catchment.

  For example, the site where the steel tower of the transmission line is installed is covered with concrete in consideration of the deterioration of the surrounding environment due to the growth of vegetation and the drainage effect. A water collecting tank is provided for collecting and draining rainwater on the concrete. As shown in FIG. 9, the water collecting pad 100 is composed of a paddle body 101 embedded in concrete (underground) C and having an upper opening, and a paddle lid 102 covering the upper opening 101a of the paddle body 101. As shown in FIG. 10, a plurality of water passage holes 102 a are formed in the lattice lid 102 in a lattice shape. In addition, the upper surface C <b> 1 of the concrete C is provided with a gradient so as to descend toward the catchment basin 100, and the lower end of the gradient coincides with the upper surface of the jar lid 102. As a result, rain water W on the concrete C flows toward the water collecting basin 100 and flows into the casket body 101 from the water passage hole 102a of the casket lid 102.

Further, a lid that can prevent dust and the like from flowing into the basket main body is known (see, for example, Patent Document 1). This cocoon lid is filled with a stone material in a frame body whose upper and lower surfaces can pass water, and prevents dust, dead leaves and the like from flowing into the cocoon body by the stone material.
JP 09-296467 A

  By the way, if there are fallen leaves Y or dust on the upper surface C1 of the concrete C, these flow together with the rainwater W or the like toward the water collecting basin 100 and accumulate on the upper surface of the culvert lid 102 as shown in FIG. Then, when the fallen leaves Y and dust accumulate on the upper surface of the lid 102 in this way, the water passage hole 102a of the lid 102 is clogged, and rainwater W does not flow into the basket body 101. As a result, rainwater W or the like accumulates on the upper surface C1 of the concrete C. For example, when inspecting or working on the steel tower, it is necessary to drain rainwater W by putting on boots and removing fallen leaves Y and garbage. And it took a lot of time and effort. Furthermore, if rainwater W accumulates for a long period of time, fly mosquitoes may be generated, water may flow out of places other than the drainage area (collection basin 100), the surrounding environment may deteriorate, and the surrounding sediment may collapse. There was a risk of causing problems. On the other hand, with the lid as described in Patent Document 1, it is possible to prevent dust and the like from flowing into the lid body, but dust and the like accumulate on the lid and cause clogging. Cannot be prevented or suppressed.

  Therefore, an object of the present invention is to provide a cover for a water collecting basin capable of suppressing the inflow of water to the water basin from being obstructed by defoliation or dust.

  In order to achieve the above-mentioned object, the invention according to claim 1 is a cover for a water collecting basin disposed on the upper side of a water basin provided with a cocoon body embedded in the ground and having an upper opening. A side cover having a plurality of water passage holes through which water passes and a side cover having a plurality of water passage holes extending along the periphery of the opening of the main body of the ridge body and covering the opening of the side cover so as to be deformable (having flexibility) And an upper cover having a plurality of water passage holes through which water passes.

  According to the present invention, when fallen leaves or garbage flows along with rainwater or the like toward the catchment basin, the side cover prevents the fallen leaves or the like from entering the opening side of the basin body, It flows into the bag main body through the water holes of the upper cover and the upper cover. Further, even when fallen leaves or the like get over the side cover and enter the opening side of the cocoon body, the upper cover does not allow fallen leaves or the like to enter the heel body. In addition, by deforming the top cover up and down, clogging of the water passage holes due to the formation of gaps between the fallen leaves on the top cover, movement of fallen leaves, etc. and accumulation of fallen leaves is prevented. To be eliminated.

  According to a second aspect of the present invention, there is provided the water collecting cover according to the first aspect, further comprising: a floating body that floats due to liquid buoyancy, wherein the upper cover floats as the floating body floats. A floating body is provided.

  According to the present invention, when the floating body floats due to rain water or the like, the upper cover floats, gaps are formed between the fallen leaves on the upper cover, or the fallen leaves move to clog the water passage holes. Prevention and elimination.

  The invention according to claim 3 is the water catchment cover according to claim 2, wherein the floating body is disposed above the upper cover, and the floating body is provided with a hanger. .

  According to the first aspect of the present invention, the side cover prevents the fallen leaves and the like from entering the opening side of the cocoon body, and the upper cover prevents the fallen leaves and the like from entering the cocoon body. Further, by deforming the upper cover, clogging of the water passage holes of the upper cover is prevented and eliminated. In this way, it is suppressed that the inflow of water into the water collecting basin is inhibited by defoliation or dust.

  According to the second aspect of the present invention, since the floating body is suspended by rainwater or the like, the clogging of the water passage hole is prevented and eliminated, so there is no need to manually deform the upper cover. In other words, if water accumulates to the extent that the floating body floats, clogging is automatically eliminated, so that water can continue to accumulate (inflow of water into the catchment can be blocked) automatically. It is suppressed.

  According to the third aspect of the present invention, the upper cover can be forcibly deformed and the clogging of the water passage holes can be prevented and eliminated by moving the floating body using the hanger. Furthermore, it becomes easy to move the entire water collecting cover by using the lifting tool.

  The present invention will be described below based on the illustrated embodiments.

  1 and 2 are a front view and a plan view showing a water collecting cover 1 according to an embodiment of the present invention. The water collecting cover 1 is arranged above (on the upper side) of the water collecting pad 100. It is a cover to be installed. Here, the catchment basin 100 has the same configuration as the conventional catchment basin, that is, the catchment basin 100 shown in FIGS. 9 and 10, and the description thereof is omitted by giving the same reference numerals.

  The catchment cover 1 mainly includes a net fixing frame (side cover) 2, an upper net (upper cover) 3, and a float (floating body) 4.

  The net fixing frame 2 is a frame body in which a net plate is formed in a cylindrical shape, and the inner diameter is set to be larger than the plane area of the catchment 100. That is, when the net fixing frame 2 is arranged on the lid 102 of the catchment 100, the inner diameter of the net fixing frame 2 is set so that the lid 102 is positioned in the net fixing frame 2, and the main body 101 The net fixing frame 2 extends along the periphery of the upper opening 101 a, that is, the periphery of the lid 102. In addition, the size of the mesh of the mesh plate is set to a size that does not allow fallen leaves Y or dust to pass through, and the mesh (opening between the yarns of the mesh) is a water passage hole through which water passes. Yes.

  The height of the mesh fixing frame 2 is such that the leaves on the concrete C cannot easily get over the mesh fixing frame 2. Further, the weight of the net fixing frame 2 is set so that the water collecting cover 1 can be stably installed without floating due to buoyancy of water and can be easily transported by human power.

  The upper net 3 is a net composed of a water-resistant rope, and the net size of the net is set to a size that does not allow fallen leaves Y or dust to pass through, and the net passes water. It is a hole. The upper net 3 is disposed so as to cover the opening (inside the cylinder) of the net fixing frame 2. That is, as shown in FIG. 3, the peripheral end portion of the upper net 3 is connected to the central portion of the inner wall surface of the net fixing frame 2, and the upper net 3 is disposed so as to cover the inside of the net fixing frame 2. Moreover, since the upper net 3 is composed of a rope, the upper net 3 has flexibility, and the developed area is set to be larger than the inner area of the net fixing frame 2. For this reason, as shown in FIG. 4, it can be freely deformed vertically and horizontally.

  The float 4 floats due to buoyancy of rainwater or the like (liquid), and is a sphere composed of a foam material or the like, or a sphere having a hollow inside. The float 4 is attached to an upper surface (upper) center portion of the upper net 3, and the upper net 3 floats as the float 4 floats, as will be described later. Further, a ring-shaped hanger 41 is provided on the top of the float 4. As described above, the net fixing frame 2, the upper net 3, and the float 4 are connected.

  Next, the operation of the water collecting tank cover 1 having such a configuration will be described. Here, the case where the catchment cover 1 is applied to the catchment installed in the site where the steel tower of the transmission line is installed will be described.

  As shown in FIG. 5, the steel tower T is installed on the concrete C, and the catchment 100 is installed directly under the center of the steel tower T. The upper surface C1 of the concrete C is provided with a gradient so as to descend toward the catchment basin 100, and the lower end of the gradient coincides with the upper surface of the lid 102 (see FIG. 9). As a result, rain water W on the concrete C flows toward the water collecting basin 100 and flows into the casket body 101 from the water passage hole 102a of the casket lid 102. In addition, a drainage pipe 103 is connected to the jar body 101 so that rainwater or the like in the jar body 101 is drained to the outside through the drainage pipe 103.

  In order to apply the catchment cover 1 to such a catchment 100, as shown in FIG. 1, the catchment basin 102 is positioned so that the catch cover 102 of the catchment 100 is located in the net fixing frame 2. The cover 1 is disposed on the water collecting tank 100. At this time, the lower end of the net fixing frame 2 comes into contact with the upper surface C1 of the concrete C.

  If, for example, it rains after the catchment cover 1 is arranged in this way, the fallen leaves Y and dust on the upper surface C1 of the concrete C flow toward the catchment 100 together with the rainwater. As shown in FIG. 3, the fallen leaves Y and dust are prevented from entering the inside of the net fixing frame 2 (on the side of the lid 102) by the net fixing frame 2. On the other hand, rainwater flows into the inside of the net fixing frame 2 through the nets (water passage holes) of the net fixing frame 2 and the upper net 3, and flows into the main body 101 through the water passage holes 102 a of the lid lid 102. Further, when the fallen leaves Y or the like get over the net fixing frame 2 and enter the inside of the net fixing frame 2, the upper net 3 prevents the fallen leaves Y or the like from entering the lid 102 side. That is, the fallen leaves Y and dust do not accumulate directly on the lid 102.

  Next, as shown in FIG. 6, when fallen leaves Y or dust accumulates on the side of the mesh fixing frame 2 and the mesh of the mesh fixing frame 2 is clogged, rainwater flows through the mesh of the upper net 3. It flows into the jar body 101 from the water passage hole 102 a of the jar lid 102.

  Further, leaf fall Y, dust and the like are accumulated on the side of the mesh fixing frame 2 and above the upper net 3, the meshes of the mesh fixing frame 2 and the upper net 3 are clogged, and rainwater collects on the upper surface C1 of the concrete C. In this case, as shown in FIG. 7, the float 4 floats upward and floats due to the buoyancy of the rainwater W. Along with the floating, the upper net 3 expands widely and floats (deforms) vertically and horizontally, and a gap is formed between the fallen leaves Y on the upper net 3 or the fallen leaves Y move. . Further, since the peripheral end of the upper net 3 is connected to the center of the inner wall surface of the net fixing frame 2, when the upper net 3 is widely deployed, the fallen leaves Y on the upper net 3 and the like are removed from the net fixing frame 2. It becomes easy to fall to the outside. As a result, the clogging of the mesh of the upper net 3 is eliminated, and the rainwater W flows from the mesh of the upper net 3 to the lid 102 side. Furthermore, when the rainwater W flows into the bag main body 101, the water level of the rainwater W is lowered, the float 4 is lowered toward the net fixing frame 2 (the lid 102), and the upper net 3 is contracted. In this way, the vertical movement of the float 4 and the expansion and contraction of the upper net 3 are performed with the fluctuation of the water level of the rainwater W.

  On the other hand, in order to prevent clogging by looking at the accumulation of fallen leaves Y and the like on the upper net 3, a hook 110a attached to the tip of the work bar 110 by the worker H is attached as shown in FIG. The float 4 is hung on the hanger 41 and the float 4 is moved up, down, left and right. As a result, a gap is formed between the fallen leaves Y on the upper net 3 in the same manner as described above, or the fallen leaves Y move, so that clogging of the mesh of the upper net 3 is eliminated or prevented.

  Further, when removing the fallen leaves Y or dust attached to the net fixing frame 2 or the upper net 3, the hook 110a of the work bar 110 is hung on the hanger 41 in the same manner as described above, and water is collected by the work bar 110. Lift the entire bag cover 1 and carry it to a predetermined place.

  As described above, according to the water collecting cover 1, first, the fallen leaves Y and dust do not collect directly on the cover 102, so that the water passage hole 102 a of the cover 102 is clogged. Therefore, it is suppressed that the inflow of water into the water collecting basin 100 (the basin body 101) is hindered by the fallen leaves Y or dust. Next, even when fallen leaves Y or dust accumulates on the side of the net fixing frame 2, water flows into the main body 101 through the net of the upper net 3. Further, even when fallen leaves Y or dust accumulates on the side of the net fixing frame 2 and above the upper net 3, clogging of the upper net 3 is eliminated or prevented by the floating and floating of the float 4. Water flows from the bowl to the main body 101 side. In this way, it is suppressed that the inflow of water into the catchment basin 100 is hindered by the fallen leaves Y and dust. As a result, rainwater W or the like does not always accumulate on the upper surface C1 of the concrete C, and generation of fly mosquitoes is prevented, and the surrounding environment is well preserved.

  In addition, since the float 4 floats due to rainwater W or the like, clogging of the upper net 3 is prevented and eliminated, so that it is not necessary to deform the upper net 3 manually. In other words, if rainwater W or the like accumulates to such an extent that the upper net 3 floats, the clogging is automatically eliminated, so that rainwater W or the like continues to accumulate (inflow of water into the catchment basin 100 is hindered). Is automatically suppressed. Furthermore, by arbitrarily deforming the upper net 3 with the work rod 110 or the like, clogging of the upper net 3, that is, clogging into the water collecting basin 100 can be easily and quickly prevented and eliminated. At this time, the work rod 110 can be easily hung from a remote place by hanging the work rod 110 on the hanger 41 of the float 4 as described above. In addition, when the entire water collecting cover 1 is transported or when the attached fallen leaves Y or dust is removed, the suspension 41 of the float 4 can be used to perform the work easily and in a short time. Moreover, such an effect can be obtained simply by placing the catchment cover 1 on the existing catchment 100, and the existing catchment 100 can be used as it is.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, the float 4 is provided, but without providing the float 4, the upper net 3 is widely expanded and deformed vertically and horizontally by human power, thereby clogging the upper net 3. You may make it eliminate and prevent. Further, the water collecting cover 1 may be configured integrally with the water collecting pad 100. For example, the net fixing frame 2 and the lid 102 of the water collecting cover 1 may be connected and integrated. Moreover, the upper opening 101a of the main body 101 may be covered only with the water collecting cover 1 without providing the water cover 102 on the water collecting pot 100. Further, the water collecting basin 100 may be a side ditch of a road or a creation site, a drainage ditch of a residential area, or the like, and the net fixing frame 2 is not limited to a cylinder but may be a square tube.
