Description
Technical Field
[0001] This utility model relates to the field of building drainage technology, and in particular to a drainage device that is easy to assemble. Background Technology
[0002] A sunroom is a transparent or semi-transparent structure built on the exterior of a residence, usually made of glass or similar materials. It is designed to maximize the use of natural light, bringing sunlight from the outside into the interior, providing people with a comfortable, bright space that is closely connected to nature. The drainage system of a sunroom usually consists of a water trough set on the roof and a drain pipe connected below the trough. The drainage trough can be quickly fixed with bolts or glue during installation, making assembly convenient.
[0003] After the drainage device is installed, leaves, branches, or firecracker paper often enter the drainage channel during use. When these debris enters the drain outlet along with the water flow, they will cover the drain outlet, causing blockage and affecting the normal drainage of the drainage device. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that leaves, branches, firecracker paper, etc. often enter the drainage trough after the drainage device is installed and used. When these debris enters the drainage outlet of the drainage trough with the water flow, they will cover the drainage outlet, causing blockage and affecting the normal drainage of the drainage device. Therefore, a drainage device that is easy to assemble is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drainage device that is easy to assemble, comprising a water tank and a drain pipe, wherein a drain hole is provided on one side of the bottom of the inner wall of the water tank, and a connecting pipe is fixedly connected to the bottom of the water tank near the drain hole. The drain pipe is installed on the outside of the bottom of the connecting pipe by a convenient device, and a protective device is provided at the top of the water tank to block and protect the top of the water tank.
[0006] The effect achieved by the above components is as follows: When installing the water tank, place the water tank in the edge groove of the top of the sunroom, and connect the bottom of the water tank to the top of the sunroom with glue. When rainwater falls on the top of the sunroom, it will enter the water tank on all four sides, flow inside the water tank to the drain hole and enter the connecting pipe, and then be discharged through the drain pipe.
[0007] Preferably, the protective device includes a mesh plate, protrusions, and L-shaped blocks. The size and shape of the outer surface of the mesh plate are adapted to the size and shape of the inner wall of one side of the water tank. The surface of the mesh plate is provided with a filter screen composed of several bent rods and diagonal rods, which are distributed alternately on the surface of the mesh plate. Two rectangular blocks are fixedly connected to both sides of the mesh plate. The bottom end of the rectangular blocks is rotatably connected to a rotating shaft. The L-shaped blocks are fixed to the outside of the rotating shaft. A torsion spring that can limit the angle of the rotating shaft is provided on the outside of the rotating shaft. Several protrusions are fixed to the outside of the water tank by welding.
[0008] The effect achieved by the above components is as follows: When installing the water tank, a mesh plate can be inserted downwards into the grooves on the four sides of the water tank. When the mesh plate moves downwards, one end of the L-shaped block at the bottom of the rectangular block on both sides contacts the surface of the protrusion on the outside of the water tank, which will push the L-shaped block to rotate outwards through the rotating shaft. If the mesh plate is pressed further, the end of the L-shaped block away from the rotating shaft will enter under the protrusion. The torsion spring pulls the rotating shaft to rotate at the original angle, so that the end of the L-shaped block away from the rotating shaft is stuck under the protrusion. The position of the L-shaped block on the outside of the protrusion and the position of the mesh plate inside the water tank are fixed. When rainwater enters the water tank, it will pass through the filter screen composed of bent rods and diagonal rods on the surface of the mesh plate. The filter screen can block the debris such as leaves and branches carried by the rainwater. And because the filter screen is composed of bent rods and diagonal rods, it is not easy for debris to enter the water tank through the gaps between the bent rods or diagonal rods.
[0009] Preferably, an auxiliary block is fixedly connected to one side of the L-shaped block, and a semi-circular groove is provided at the bottom end of the auxiliary block.
[0010] The effect achieved by the above components is as follows: When it is necessary to remove the mesh plate fixed to the outside of the water tank, you can use your hand to press against the semi-circular groove at the bottom of the auxiliary block connected to the L-shaped blocks on both sides of the mesh plate, push the auxiliary block to control the L-shaped block to rotate outward so that one end of the L-shaped block is away from the surface of the protrusion, then lift the mesh plate up a distance so that one end of the L-shaped block is above the protrusion, release the auxiliary block and pull out the mesh plate.
[0011] Preferably, a plurality of protruding strips are fixedly connected to the end of the L-shaped block away from the rotating shaft. The protruding strips are made of rubber and are linearly distributed on one side of the L-shaped block.
[0012] The effect achieved by the above components is that the side of the L-shaped block with the rubber ridge is more stable and less prone to slippage when it contacts the bottom end of the ridge.
[0013] Preferably, a stop block is fixedly connected to one side of the rectangular block, and the stop block and the rectangular block form a certain angle to limit the rotation angle of the L-shaped block on one side of the rectangular block.
[0014] The effect achieved by the above components is that when the L-shaped block is pulled outward and rotated too much, one side of the auxiliary block will abut against one end of the stop block. The stop block can limit the rotation angle of the L-shaped block and prevent the L-shaped block from rotating outward too much, which could damage the torsion spring.
[0015] Preferably, a mounting bracket is fixedly connected to the bottom end of the water tank near the connecting pipe. The convenient device includes a grooved rod and a threaded pipe. The grooved rod is fixed to the outside of the drain pipe for connection with the mounting bracket. A telescopic hose is rotatably provided at the bottom end of the threaded pipe. The outer surface of the threaded pipe is threaded to the inner wall of the connecting pipe for connecting the connecting pipe, the telescopic hose, and the drain pipe. The bottom end of the telescopic hose is fixedly connected to the top end of the drain pipe.
[0016] The aforementioned components achieve the following effects: When installing the drain pipe, attach the two grooved rods on the outer side of the drain pipe to the outer surface of the mounting bracket and fix the grooved rods to the mounting bracket with bolts. Then, insert one end of the threaded tube at the top of the telescopic hose into the inside of the connecting pipe, rotate the threaded tube to screw it into the inside of the connecting pipe, and at the same time, the telescopic hose will extend. When the water tank drains through the drain hole, it will pass through the connecting pipe and the threaded tube to enter the drain pipe. If there is an abnormal blockage at the drain hole or the connecting pipe, the threaded tube can be rotated to unscrew it out of the connecting pipe. Pulling the telescopic hose will change the angle of the telescopic hose, making it easy to clean the blockage inside the drain hole and the connecting pipe or the threaded tube without removing the drain pipe.
[0017] Preferably, a rubber sealing ring is fixedly connected to the top end of the telescopic hose, and the rubber sealing ring is located outside the connection between the telescopic hose and the threaded pipe.
[0018] The effect achieved by the above components is that when the threaded pipe is screwed into the inside of the connecting pipe, the rubber sealing ring will fit against the bottom end of the connecting pipe. The rubber sealing ring can further seal the outside of the connection between the threaded pipe and the connecting pipe, and minimize water leakage through the outside of the threaded pipe during drainage.
[0019] Preferably, a protruding rod is fixedly connected to one side of the bottom end of the threaded tube, and the protruding rod protrudes out of the outer side of the threaded tube.
[0020] The effect achieved by the above components is that by pressing the protruding rod on the outside of the threaded tube with your hand, you can more easily push the protruding rod to control the rotation of the threaded tube and connect or disconnect the threaded tube from the connecting pipe.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, a protective device is installed by mounting mesh plates at the top of the four sides of the water tank. When rainwater enters the water tank, it passes through the filter screen on the surface of the mesh plate. Since the filter screen is composed of bent rods and diagonal rods, it is difficult for debris to enter the water tank through the gaps between the bent rods or diagonal rods. This minimizes the risk of debris entering the water tank and clogging the drainage holes inside the water tank, thus affecting the normal drainage function of the water tank.

[0029] Example 1, such as Figure 1-2 As shown, a conveniently assembled drainage device includes a water tank 1 and a drain pipe 6. A drain hole 4 is provided on one side of the bottom of the inner wall of the water tank 1. A connecting pipe 5 is fixedly connected to the bottom of the water tank 1 near the drain hole 4. The drain pipe 6 is installed on the outside of the bottom of the connecting pipe 5 through a convenient device 3. A protective device 2 is provided at the top of the water tank 1 to block and protect the top of the water tank 1. When installing the water tank 1, the water tank 1 is placed in the edge groove of the top of the sunroom. The bottom of the water tank 1 is connected to the top of the sunroom with glue. When rainwater falls on the top of the sunroom, it will enter the water tank 1 on all four sides, flow into the drain hole 4 inside the water tank 1, enter the connecting pipe 5, and then be discharged through the drain pipe 6.
[0030] Reference Figure 1-4As shown in this embodiment: the protective device 2 includes a mesh plate 22, a protrusion 21, and an L-shaped block 28. The size and shape of the outer surface of the mesh plate 22 are adapted to the size and shape of the inner wall of one side of the water tank 1. A filter screen composed of several bent rods 23 and inclined rods 24 is provided on the surface of the mesh plate 22. The bent rods 23 and inclined rods 24 are distributed alternately on the surface of the mesh plate 22. Two rectangular blocks 25 are fixedly connected to both sides of the mesh plate 22. A rotating shaft 26 is rotatably connected to the bottom end of the rectangular block 25. The L-shaped block 28 is fixed to the outside of the rotating shaft 26. A torsion spring 27 is provided on the outer side of the rotating shaft 26 to limit the angle of the rotating shaft 26; several protrusions 21 are fixed to the outer side of the water tank 1 by welding. When installing the water tank 1, a mesh plate 22 can be inserted downward into the grooves on the four sides of the water tank 1. When the mesh plate 22 moves downward, when one end of the L-shaped block 28 at the bottom of the rectangular block 25 on both sides contacts the surface of the protrusion 21 on the outer side of the water tank 1, it will push the L-shaped block 28 to rotate outward through the rotating shaft 26. If the mesh plate 22 is pressed further, the end of the L-shaped block 28 away from the rotating shaft 26 will enter the groove. Below the protrusion 21, the torsion spring 27 pulls the rotating shaft 26 to rotate back to its original angle, causing the end of the L-shaped block 28 away from the rotating shaft 26 to be locked below the protrusion 21. This fixes the position of the L-shaped block 28 outside the protrusion 21 and the position of the mesh plate 22 inside the water tank 1. When rainwater enters the water tank 1, it passes through the filter screen composed of bent rods 23 and inclined rods 24 on the surface of the mesh plate 22. The filter screen can block debris such as leaves and branches carried by the rainwater. Furthermore, because the filter screen is composed of bent rods 23 and inclined rods 24, it effectively blocks debris. It is not easy for debris to enter the water tank 1 through the gaps between the bent rods 23 or the diagonal rods 24. By setting up a protective device 2 and installing mesh plates 22 at the top of the four sides of the water tank 1, rainwater enters the water tank 1 and passes through the filter screen on the surface of the mesh plate 22. Since the filter screen is composed of bent rods 23 and diagonal rods 24, it is not easy for debris to enter the water tank 1 through the gaps between the bent rods 23 or diagonal rods 24. This minimizes the possibility of debris entering the water tank 1 and clogging the drainage holes 4 inside the water tank 1, thus affecting the normal drainage function of the water tank 1.
[0031] Reference Figure 2-4As shown in this embodiment: an auxiliary block 29 is fixedly connected to one side of the L-shaped block 28. The bottom end of the auxiliary block 29 has a semi-circular groove. When it is necessary to remove the mesh plate 22 fixed to the outside of the water tank 1, you can use your hand to press against the semi-circular groove at the bottom end of the auxiliary block 29 connected to the L-shaped block 28 on both sides of the mesh plate 22, push the auxiliary block 29 to control the L-shaped block 28 to rotate outward so that one end of the L-shaped block 28 is away from the surface of the protrusion 21. Then lift the mesh plate 22 up a distance so that one end of the L-shaped block 28 is above the protrusion 21. Release the auxiliary block 29 and pull out the mesh plate 22. The end of the L-shaped block 28 away from the rotating shaft 26 is fixedly connected to several protrusions 210. The protrusions 210 are made of rubber and are linearly distributed on one side of the L-shaped block 28. When the side of the L-shaped block 28 with the rubber protrusions 210 contacts the bottom end of the protrusion 21, it is more stable and less prone to slippage.
[0032] Reference Figure 2-4 As shown in this embodiment: a stop block 211 is fixedly connected to one side of the rectangular block 25. The stop block 211 and the rectangular block 25 form a certain angle to limit the rotation angle of the L-shaped block 28 on one side of the rectangular block 25. When the L-shaped block 28 is pulled to rotate outward by too large an angle, one side of the auxiliary block 29 will abut against one end of the stop block 211. The rotation angle of the L-shaped block 28 can be limited by the stop block 211, so as to avoid the L-shaped block 28 rotating outward by too large an angle and causing damage to the torsion spring 27.
[0033] Reference Figure 1 and Figure 5 As shown in this embodiment: a mounting bracket 7 is fixedly connected to the bottom end of the water tank 1 near the connecting pipe 5. The convenient device 3 includes a grooved rod 31 and a threaded pipe 32. The grooved rod 31 is fixed to the outside of the drain pipe 6 for connection with the mounting bracket 7. A telescopic hose 33 is rotatably provided at the bottom end of the threaded pipe 32. The outer surface of the threaded pipe 32 is threadedly connected to the inner wall of the connecting pipe 5 for connecting the connecting pipe 5, the telescopic hose 33, and the drain pipe 6. The bottom end of the telescopic hose 33 is fixedly connected to the top end of the drain pipe 6. When installing the drain pipe 6, the two grooved rods 31 on the outside of the drain pipe 6 are respectively attached to the outer surface of the mounting bracket 7 and bolts are used to connect the grooved rods 31 to the mounting bracket. 7. Secure the hose, then insert one end of the threaded tube 32 at the top of the flexible hose 33 into the inside of the connecting pipe 5. Rotate the threaded tube 32 to screw it into the inside of the connecting pipe 5. At the same time, the flexible hose 33 will extend. When the water tank 1 drains through the drain hole 4, it will pass through the connecting pipe 5 and the threaded tube 32 to enter the drain pipe 6. If there is an abnormal blockage at the drain hole 4 or the connecting pipe 5, the threaded tube 32 can be rotated to unscrew it out of the connecting pipe 5. Pull the flexible hose 33 to change its angle, which makes it easier to clean the blockage inside the drain hole 4 and the connecting pipe 5 or the threaded tube 32 without removing the drain pipe 6.
[0034] Reference Figure 1 and Figure 5As shown in this embodiment: a rubber sealing ring 34 is fixedly connected to the top of the telescopic hose 33. The rubber sealing ring 34 is located on the outside of the connection between the telescopic hose 33 and the threaded pipe 32. When the threaded pipe 32 is screwed into the connecting pipe 5, the rubber sealing ring 34 will fit against the bottom end of the connecting pipe 5. The rubber sealing ring 34 can further seal the outside of the connection between the threaded pipe 32 and the connecting pipe 5, and minimize water leakage through the outside of the threaded pipe 32 during drainage. A protruding rod 35 is fixedly connected to one side of the bottom end of the threaded pipe 32. The protruding rod 35 protrudes out of the outside of the threaded pipe 32. By pressing the protruding rod 35 on the outside of the threaded pipe 32 with your hand, you can more easily push the protruding rod 35 to control the rotation of the threaded pipe 32 to connect or disconnect the threaded pipe 32 from the connecting pipe 5.
[0035] Working principle: When installing the water tank 1, place the water tank 1 in the edge groove of the sunroom's top. Connect the bottom of the water tank 1 to the top of the sunroom with glue. Place a mesh plate 22 downwards into the grooves on each of the four sides of the water tank 1. When the mesh plate 22 moves downwards, one end of the L-shaped block 28 at the bottom of the rectangular blocks 25 on both sides contacts the surface of the protrusion 21 on the outside of the water tank 1, pushing the L-shaped block 28 to rotate outwards via the pivot 26. Continue pressing the mesh plate 22 to move the L-shaped block 28 away from the water tank 1. One end of the rotating shaft 26 will enter under the protrusion 21. The torsion spring 27 pulls the rotating shaft 26 to rotate back to its original angle, so that the end of the L-shaped block 28 away from the rotating shaft 26 is locked under the protrusion 21. The position of the L-shaped block 28 on the outside of the protrusion 21 and the position of the mesh plate 22 inside the water tank 1 are fixed. The two grooved rods 31 on the outside of the drain pipe 6 are respectively attached to the outer surface of the mounting bracket 7 and the grooved rods 31 are fixed to the mounting bracket 7 with bolts. Then the threaded tube 3 at the top of the telescopic hose 33 is... 2. Insert one end into the inside of the connecting pipe 5, rotate the threaded pipe 32 to screw the threaded pipe 32 into the inside of the connecting pipe 5, and install the drain pipe 6 below the water tank 1. When rainwater falls on the top of the sunroom, it will enter the water tank 1 on all four sides. When the rainwater enters the water tank 1, it will pass through the filter screen composed of bent rods 23 and inclined rods 24 on the surface of the mesh plate 22. The filter screen can block the debris such as leaves and branches carried by the rainwater. Since the filter screen is composed of bent rods 23 and inclined rods 24, it is not easy for debris to enter the water tank 1 through the gaps between the bent rods 23 or inclined rods 24. The water flows into the drain hole 4 and enters the connecting pipe 5, and then is discharged through the drain pipe 6. If there is an abnormal blockage at the drain hole 4 or the connecting pipe 5, the threaded pipe 32 can be rotated to unscrew the threaded pipe 32 out of the inside of the connecting pipe 5. Pull the telescopic hose 33 to change the angle of the telescopic hose 33, and clean the blockage inside the drain hole 4 and the connecting pipe 5 or the threaded pipe 32 without removing the drain pipe 6.
