Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection, in particular to a rainwater collection device for municipal engineering. Background Art

[0002] The collection and utilization of rainwater is an important topic in municipal engineering construction, and it is of great significance in saving resources, preventing floods, protecting the environment, and studying water bodies.

[0003] To collect and utilize rainwater, a water storage tank is generally used. The water storage tank has good sealing performance and can effectively prevent the collected rainwater from evaporating and causing resource waste. However, since rainwater is generally mixed with a large amount of impurities, it is easy to produce odors when left alone for a long time, which is not convenient for direct use. In addition, if rainwater containing impurities is accumulated for a long time, impurities are easily accumulated at the outlet of the water storage tank, resulting in a decrease in water output or blockage.

[0004] In response to the above problems, the utility model patent with announcement number CN201411740Y discloses a rainwater purification reservoir, which effectively filters impurities in rainwater by setting a vertical filter grid in the reservoir, and has a certain purification effect on rainwater. However, although the reservoir structure can filter rainwater, the impurities filtered by the filter grid are easily accumulated on the filter grid, and the staff generally need to climb a ladder to enter the reservoir, and it is not advisable to bring too many cleaning tools. Therefore, it is a very tedious task to enter the reservoir to clean the filtered impurities. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a rainwater collection device for municipal engineering to solve the problem that impurities filtered in the water storage tank in the prior art are difficult to clean.

[0023] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0024] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0025] Embodiment 1

[0026] Combination Figures 1 to 3 As shown, a rainwater collection device for municipal engineering includes a water storage tank 1, a vertical filter grille 2 is arranged in the water storage tank 1, a filter pool 11 is arranged on the left side of the filter grille, and a purification pool 12 is arranged on the right side. A vertical first fixing rod 21 is arranged at both ends of the filter grille 2, and a bolt hole is arranged on the first fixing rod 21, and the first fixing rod 21 is installed in the water storage tank 1. The filter grille 2 and the water storage tank 1 are arranged in a detachable connection mode, which is convenient for disassembling and cleaning the filter grille 1 on the one hand, and convenient for the staff to walk between the filter pool 11 and the purification pool 12 on the other hand. A water inlet 3 is arranged on the top of the filter pool 11, a water outlet 4 is arranged on the bottom of the purification pool 12, and a maintenance port 5 is arranged on the top surface of the filter pool 11, and a ladder 7 arranged on the side wall of the filter pool 11 is arranged below the maintenance port 5, so as to facilitate the staff to enter the water storage tank 1 from the maintenance port 5.

[0027] A dirt collecting bag 6 is fixedly installed at the bottom of the filter grille 2, and the length of the dirt collecting bag 6 is ensured to be the same as the width of the filter grille 2 as much as possible, so as to collect as many impurities blocked by the filter grille 2 as possible. The first fixed rods 21 at both ends of the filter grille 2 are integrally provided with plug rods 22. The dirt collecting bag 6 includes a net bag part 61 and a bag cover 62. The two ends of the net bag part 61 are respectively provided with a second fixed rod 611 and a side plate 613. The bottom of the second fixed rod 611 is a slot, so that the second fixed rod 611 can be inserted into the plug rod 22 to prevent the net bag part 61 from shaking in the horizontal direction. At the same time, a fixed mounting hole 6110 is also provided on the second fixed rod 611, and a mounting hole is also provided at the corresponding position of the first fixed rod 21. The second fixed rod 611 is fixed to the first fixed rod 21 by a positioning bolt 8, so that the dirt collecting bag 6 is more stably fixed to the filter grille 2, and the gap between the dirt collecting bag 6 and the filter grille 2 is smaller to prevent impurities from falling into the gap.

[0028] The net bag portion 61 is L-shaped when viewed from the side, and a guide surface 612 is provided on its top, which is inclined in the direction of the filter grille 2, so that impurities blocked above the filter grille 2 can slide down along the guide surface. One side of the net bag portion 61 is open for collecting the fallen impurities. The bottom of the net bag portion 61 is rotatably connected to a bag cover 62 via a rotating shaft 63. The bag cover 62 can be placed flat on the bottom surface of the filter tank. When the dirt collecting bag 6 needs to be cleaned, the bag cover 62 is flipped upward to the upper part of the net bag portion 61, thereby closing the opening and forming a closed space for the dirt collecting bag 6 (the net bag portion 61 is a partial or complete filter screen structure to prevent water in the reservoir from remaining in the dirt collecting bag 6). A first positioning hole 614 is provided on the side plate 613, and a second positioning hole 621 is provided on the bag cover 62. When the bag cover 62 is turned over to the point where the second positioning hole 621 overlaps with the first positioning hole 614, the bag cover 62 can be locked by bolts to facilitate subsequent tilting or removal of the dirt collecting bag 6, thereby facilitating the cleaning of impurities in the dirt collecting bag 6. In order to ensure that impurities in the filter pool 11 can enter the dirt collecting bag 6, the bottom of the filter pool 11 can be arranged to tilt toward one side of the filter grille 2, so that impurities in the rainwater slide toward one side of the dirt collecting bag 6 and finally enter the dirt collecting bag 6.

[0029] like Figure 1 As shown, a dosing port is provided at the top of the purification tank 12. After the rainwater is filtered through the filter grille 2 and enters the purification tank 12, alum, disinfectant or chlorination disinfection can be added to the purification tank 12 to disinfect the rainwater in the purification tank 12. An activated carbon purification box 10 is also fixedly installed at the bottom of the purification tank 12. Activated carbon is placed inside the activated carbon purification box 10, and a number of through holes are provided on the box body to adsorb and purify the rainwater. The activated carbon purification box 10 is in contact with one side of the filter grille 2, providing a certain support thereto to prevent it from being displaced or damaged due to one-way acceptance.

[0030] The utility model provides a dirt collecting bag 6 in the filter pool 11. After drainage is completed, the dirt collecting bag 6 is closed by rotating the bag cover 62. The dirt collecting bag 6 can then be disassembled and cleaned by tilting or taking out the water tank 1. The steps of cleaning impurities are convenient and efficient, and the utility model is suitable for popularization and use.
