Description
Technical Field
[0001] The present invention relates to the technical field of drainage troughs, and more specifically, to a novel detachable drainage trough. Background Art
[0002] A drainage trough, also known as a drainage ditch or drainage channel, is a facility used to guide, discharge, and collect liquids (usually water). It is widely used in multiple fields such as construction, roads, gardens, and industry. In construction, drainage troughs can be installed at the edges of roofs, basements, bathrooms, etc. to drain rainwater and domestic sewage; in road engineering, drainage troughs on both sides of the road can promptly drain surface water on the road to ensure driving safety; in garden landscapes, drainage troughs help maintain the growth environment of plants and avoid damage to plants caused by waterlogging.
[0003] Regarding drainage troughs, there are many existing technologies, for example:
[0004] According to Chinese Patent Application No.: CN202322901209.2, specifically a drainage trough, which includes a trough body connected integrally in sequence. A cover plate is slidably connected to the upper side of the trough body, and a connection component for connecting between trough bodies is arranged on the trough body; the trough body has a trapezoidal trough surface with an open upper end, convex platforms are arranged at the upper ends of both sides of the trough body, leakage holes are distributed at intervals on the cover plate, and the connection component includes a connection plate arranged at one end of the trough body, and a limiting rib is arranged at the upper end of the connection plate. Through the arrangement of the trough body and the connection component in the present invention, the sunken end of the trough body corresponds to the connection plate of the adjacent trough body up and down. The limiting rib is inserted into the groove to align the end faces of the adjacent trough bodies. Then, bolts are inserted through the adjacent connecting ears and tightened to connect the trough bodies into the required length in sequence. Then, the connecting ribs on both sides of the cover plate are inserted into the sliding grooves on the upper side of the trough body for limitation, enabling the construction of the drainage trough to be carried out in a semi-finished product assembly operation, improving the installation and construction efficiency of the drainage trough.
[0005] However, in the above technology, most of the internal designs of the drainage trough are welded together, and the main parts cannot be disassembled. When there is poor drainage or a malfunction, it is impossible to clean the debris inside the drainage trough, and it is not convenient to carry out repairs and regular maintenance; when the drainage trough is under the long-term action of factors such as pressure, flow rate, and alternating stress, corrosion will occur inside. Moreover, in existing drainage troughs, generally only a grille is designed at the top for filtration, but the holes in the grille are relatively large, and it cannot effectively filter some small-volume debris or other foreign objects that affect drainage, resulting in debris accumulation, difficult drainage, and even blockage. Summary of the Invention
[0006] The present invention aims at the technical problems existing in the prior art and provides a novel detachable drainage trough to solve the problems that the internal structure of the existing drainage trough is relatively fixed, not convenient for disassembly for repair and regular maintenance, and the filtration effect is poor, prone to debris accumulation and difficult drainage.
[0007] To achieve the above object, the present invention provides a novel detachable drainage trough, including a box body. At the upper end inside the box body, a grille is provided. Inside the box body, a water inlet pipe is provided. At the lower end outside the water inlet pipe, a water inlet pipe ring plate is fixedly connected. At the lower end inside the water inlet pipe, a plurality of water inlet grooves are circularly arranged. Inside the water inlet grooves, a filter net is snap-connected. Inside the water inlet pipe, a drain pipe is provided. At a position close to the bottom of the box body outside the drain pipe, a drain pipe ring plate is fixedly connected.
[0008] The beneficial effects of the present invention are as follows:
[0009] 1. When the drainage trough needs to be disassembled and maintained, only the grille needs to be removed from the inside of the box body, and then the water inlet pipe and the drain pipe are respectively threadedly connected to the inside and bottom of the box body through bolts. By rotating the bolts to separate from the box body, the water inlet pipe is pulled out from the inside of the box body, and the drain pipe is disassembled from the bottom of the box body, thus facilitating the disassembly of the internal structure of the drainage trough, facilitating the cleaning of internal sundries, and performing regular inspections and maintenance. Moreover, the connection method between the filter net and the water inlet groove is simple, and the filter net can be separately disassembled, facilitating the maintenance and replacement of the filter net.
[0010] 2. During the use of the drainage trough, the water source is double-filtered through the grille and the filter net inside the water inlet pipe, avoiding the accumulation of impurities in the water, resulting in drainage difficulties or even blockages, improving the filtering effect, and saving the labor cost of inspection and maintenance.
[0011] On the basis of the above technical solutions, the present invention can be further improved as follows.
[0012] Preferably, a support plate is fixedly connected to the upper end inside the box body. The height of the position where the support plate is located ensures that the grille is at the same horizontal height as the top of the box body after being placed. The width of the support plate ensures that sufficient support force is provided for the grille. The grille includes a connecting plate, the connecting plate is installed on the top of the support plate, and a filtering part is fixedly connected to the top of the connecting plate. The diameter of the filtering part is smaller than the inner diameter of the box body, and there is a certain gap between it and the box body.
[0013] The beneficial effect of adopting the above further solution is that while ensuring the stable installation of the grille, it is convenient for the installation and disassembly of the grille, improving the convenience of the drainage trough.
[0014] Preferably, a cover plate is installed on the top of the water inlet pipe. Both the water inlet pipe ring plate and the drain pipe ring plate are threadedly connected to the bottom of the box body through bolts.
[0015] The beneficial effects of adopting the above further solution are as follows: The connection between the cover plate and the water inlet pipe is simple, which facilitates the disassembly of the cover plate for maintaining the structure. The water inlet pipe and the drain pipe can be conveniently disassembled and taken out to clean the internal sundries, and regular inspection and maintenance can be carried out. After disassembly, the corroded part of the inner wall can be subjected to anti-corrosion treatments such as secondary spraying to extend its service life.
[0016] Preferably, a round hole is provided at the bottom of the box body. The inner diameter of the round hole is slightly larger than the outer diameter of the drain pipe. A sealing ring is fixedly connected inside the round hole to seal between the round hole and the drain pipe. The outer length of the filter screen is the same as the inner length of the water inlet tank. A baffle slightly larger than the length and width of the bottom is provided at the top of the filter screen to seal the connection between the filter screen and the water inlet tank.
[0017] The beneficial effects of adopting the above further solution are as follows: It ensures the tightness of multiple joints of the drain tank, guarantees the drainage effect of the drain tank, avoids sewage from leaking out of the joints and affecting the external environment, and ensures the effective use of the drain tank.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] Its design form is a detachable structure. The connections between the water inlet pipe, the drain pipe and the box body are all connected by bolts, which can be conveniently disassembled and taken out to clean the internal sundries, and regular inspection and maintenance can be carried out. After disassembly, the corroded part of the inner wall can be subjected to anti-corrosion treatments such as secondary spraying to extend the service life; the double-filter design of the grille and the built-in filter screen of the water inlet pipe can filter out most of the foreign objects affecting drainage at the front end, improve the filtering effect, and save the labor cost of inspection and maintenance.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] See also Figures 1-5 As shown, the present embodiment provides a novel detachable drainage trough, including a box body 1. Considering that the internal design of the drainage trough in the prior art is mostly welded into one body, the main parts cannot be disassembled, and when encountering poor drainage or failure, it is impossible to clean the internal debris of the drainage trough, and it is not convenient to carry out inspection and regular maintenance; when the drainage trough is subjected to the long-term action of factors such as pressure, flow velocity and cross strain, the internal corrosion of the drainage trough will occur. Therefore, a grille 2 is provided at the upper end of the box body 1, and a water inlet pipe 3 is provided inside the box body 1. The lower end of the outer side of the water inlet pipe 3 is fixedly connected with a water inlet pipe ring plate 32, and the lower end of the inside of the water inlet pipe 3 is circularly provided with a plurality of water inlet grooves 33. Considering that the existing drainage troughs generally only filter through the grille 2, but the holes of the grille 2 are relatively large, and cannot effectively filter some small debris or other foreign objects that affect drainage. , which leads to accumulation of debris, drainage difficulty and even blockage. Therefore, a filter screen 34 is snap-connected inside the water inlet trough 33, with a double filtering design, and the connection method between the filter screen 34 and the water inlet trough 33 is simple, which can realize the separate disassembly of the filter screen 34, and is convenient for maintenance and replacement of the filter screen 4. Most of the foreign matter that affects drainage can be filtered out at the front end, which improves the filtering effect and saves the labor cost of inspection and maintenance. A drain pipe 4 is arranged inside the water inlet pipe 3, and a drain pipe ring plate 41 is fixedly connected to the outside of the drain pipe 4 near the bottom of the box body 1. The connections between the water inlet pipe 3, the drain pipe 4 and the box body 1 are all connected by bolts 5, which can be easily disassembled and taken out to clean the internal debris, and regular inspection and maintenance can be carried out. After disassembly, the corroded inner wall can be subjected to secondary spraying and other anti-corrosion treatments to extend the service life.
[0033] The improvement of this embodiment lies in that its design form is a detachable structure. The connection methods between the water inlet pipe 3, the drain pipe 4 and the box body 1 are simple, which can facilitate the disassembly and removal to clean the internal sundries, conduct regular inspection and maintenance. After disassembly, anti-corrosion treatments such as secondary spraying can be carried out on the corroded parts of the inner wall, extending the service life. The double-filter design of the grille 2 and the filter screen 34 inside the water inlet pipe 3 can filter out most of the foreign matters affecting drainage at the front end, improving the filtering effect and saving the labor cost of inspection and maintenance.
[0034] Specifically, considering that the grille 2 needs to be connected to the box body 1 for preliminary filtration of the water source, in order to ensure the convenience of installation and disassembly of the grille 2 and that it will not affect the use after installation, a support plate 11 is fixedly connected to the upper end inside the box body 1. The height of the position where the support plate 11 is located ensures that the horizontal height of the grille 2 after placement is the same as the top of the box body 1. The width of the support plate 11 ensures that it provides sufficient support force for the grille 2. The grille 2 includes a connecting plate 21, the connecting plate 21 is installed on the top of the support plate 11, and a filtering part 22 is fixedly connected to the top of the connecting plate 21. The diameter of the filtering part 22 is smaller than the inner diameter of the box body 1, and there is a certain gap between it and the box body 1, thus facilitating the installation and disassembly of the grille 2.
[0035] Considering that the water inlet pipe 3 and the drain pipe 4 need to be maintained regularly, in order to facilitate the maintenance efficiency and convenience of the water inlet pipe 3 and the drain pipe 4, a cover plate 31 is installed on the top of the water inlet pipe 3. The connection between the cover plate 31 and the water inlet pipe 3 is simple, which is convenient for disassembling the cover plate 31 to maintain the structure. The water inlet pipe ring plate 32 and the drain pipe ring plate 41 are both threadedly connected to the bottom of the box body 1 through bolts 5, which can facilitate the disassembly and removal to clean the internal sundries, conduct regular inspection and maintenance. After disassembly, anti-corrosion treatments such as secondary spraying can be carried out on the corroded parts of the inner wall, extending the service life.
[0036] Considering the sealing performance between the joints of the structures of the drainage tank to prevent water from overflowing from the joints and affecting the drainage effect, a round hole 12 is provided at the bottom of the box body 1. The inner diameter of the round hole 12 is slightly larger than the outer diameter of the drain pipe 4. A sealing ring 6 is fixedly connected inside the round hole 12 to seal between the round hole 12 and the drain pipe 4. The outer length of the filter screen 34 is the same as the inner length of the water inlet tank 33. A baffle slightly larger than the length and width of the bottom is provided at the top of the filter screen 34 to seal the connection between the filter screen 34 and the water inlet tank 33, ensuring the sealing performance of multiple joints and the drainage effect of the drainage tank.
[0037] In summary, the working principle of this solution is as follows:
[0038] First, the sewage enters the interior of the box body 1 from the top of the box body 1. After preliminary filtration by the grille 2, it enters the bottom of the box body 1, then enters the interior of the water inlet pipe 3 from the water inlet trough 33. The filter screen 34 inside the water inlet trough 33 performs secondary filtration on the sewage. The double-filtration design can filter out most of the foreign matters affecting drainage at the front end, improving the filtration effect, saving the labor cost of maintenance, avoiding blockage, and ensuring the normal operation of drainage. When the pressure difference between the interior of the water inlet pipe 3 and the box body 1 reaches a certain value, a siphon phenomenon is formed, and then the sewage is discharged through the drain pipe 4. When it is necessary to repair and maintain the interior of the drainage trough, only the grille 2 needs to be disassembled and removed from the interior of the box body 1. Then, both the water inlet pipe 3 and the drain pipe 4 are respectively threadedly connected to the interior and the bottom of the box body 1 through bolts 5. By rotating the bolts 5 to separate them from the box body 1, the water inlet pipe 3 is pulled out from the interior of the box body 1, and the drain pipe 4 is disassembled from the bottom of the box body 1, thereby facilitating the disassembly of the internal structure of the drainage trough, facilitating the cleaning of internal sundries, performing regular maintenance, and thus extending the service life of the drainage trough.
