Description

Technical Field

[0001] The utility model belongs to the technical field of water storage devices, and particularly relates to a municipal rainwater storage device. Background Technique

[0002] Rainwater storage refers to engineering facilities for collecting, storing, and regulating the utilization of rainwater, which is an important technology for urban rainwater management and utilization. In cities, it can be used for non-drinking water purposes such as garden greening, toilet flushing, and car washing, reducing the dependence on tap water.

[0003] In the Chinese patent with the publication number CN214657645U, a municipal rainwater storage device is mentioned, belonging to the field of water storage devices. A municipal rainwater storage device includes a box body. A water outlet pipe is fixedly connected to the left side of the box body, a sewage pipe is fixedly connected to the lower end of the box body, a water collection cover is fixedly connected to the upper end of the box body, a fixing plate is fixedly connected to the inner wall of the box body, two symmetrical fixing rods are fixedly connected to the upper end of the fixing plate, a cushion block is fixedly sleeved on the surface of the fixing rod, the lower end of the cushion block is in contact connection with the fixing plate, a positioning rod is rotatably sleeved on the surface of the fixing rod, and a limiting cap is fixedly connected to the upper end of the fixing rod; although this device can well prevent the evaporation and loss of rainwater, and the arranged baffle is convenient for staff to manually disassemble, facilitating the staff to clean the inner wall of the box body, however, during the use of this water storage device, since the device is installed in the green belt, the surrounding environment is likely to bring various impurities, such as fallen leaves, dust, and other particulate matters. The filter screen arranged inside the device can intercept most of the impurities, but dust and other particulate matters cannot be effectively intercepted. Also, because multiple water inlet pipes are arranged inside the device, dust is likely to accumulate inside the pipe wall. When blockage occurs due to the accumulation of impurities and dust, although the device is designed to be convenient for disassembly and assembly, it is not convenient to clean in actual operation, which is both time-consuming and laborious. Therefore, for the maintenance of the device, frequent cleaning work not only increases the maintenance cost but also reduces the use efficiency of the device;

[0004] In addition, when this water storage device is in use, the filtration effect of a single filter screen on rainwater is not high, and a large amount of impurities and particulate matters are not effectively intercepted during the filtration process, resulting in excessive impurities remaining in the rainwater. These impurities not only reduce the quality of the rainwater but also have an adverse impact on the normal use of the water storage device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a municipal rainwater storage device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

The box body is fixedly inserted and connected between the diversion pipe and the collecting mechanism;

[0011] The collecting mechanism includes a water receiving hopper, a water inlet pipe, a limiting ring and a grid plate. The water inlet pipe is fixedly connected to the bottom end of the water receiving hopper. The limiting ring is fixedly inserted and connected to the inner wall of the water receiving hopper. The grid plate is movably inserted and connected inside the water receiving hopper. The water inlet pipe is fixedly inserted and connected to the top end of the filtering box.

[0012] Preferably, a base is fixedly connected to the bottom end of the water storage bucket. Both sides of the bottom end of the base are fixedly connected with support seats. One end of the filtering box is fixedly connected with a support frame. The end of the support frame away from the filtering box is fixedly connected to the outer surface of the water storage bucket.

[0013] Preferably, the lower part of the water receiving hopper is of a conical structure, and the bottom end of the grid plate is in close contact with the limiting ring.

[0014] Preferably, the filter screen structure includes a filter plate, a sliding groove, a sliding seat, a telescopic rod, a spring and a wire brush.

[0015] Preferably, the spring is fixedly connected between the sliding seat and the telescopic rod, and both sides of the bottom end of the wire brush are in close contact with the top end of the filter plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] (1) By setting up a box body, a filter plate, a sliding groove, a sliding seat, a telescopic rod, a spring and a wire brush, the condition on the filter plate can be observed through the observation window. When there are too many impurities on the filter plate, the sealing door is opened. The staff holds the middle of the wire brush and presses the wire brush downward, so that both ends of the wire brush fit downward against the top of the filter plate, and then pulls the wire brush, so that both sides of the wire brush clean both sides of the top of the filter plate, thus facilitating the cleaning of the filter plate. Pull the grid plate, and the grid plate disengages from the water receiving hopper, so that the impurities on the grid plate can be cleaned.

[0018] (2) By setting up a diversion pipe, a sedimentation pipe, a connecting cover, a water receiving hopper, a limiting ring and a grid plate, when rainwater falls, it will first pass through the grid plate. The main function of this step is to filter out larger impurities in the rainwater, such as leaves, paper, etc. The rainwater that has been preliminarily filtered will smoothly flow into the lower part of the water receiving hopper. Next, the rainwater will be guided into the box body through the water inlet pipe. Inside the box body, the rainwater will be finely filtered by the filter plate again to remove finer suspended solids and pollutants, and then be introduced into the water storage bucket through the connecting pipe for storage. During the diversion process, the impurities sink downward due to their weight, so that the impurities are introduced into the sedimentation pipe. Most of the impurities in the rainwater can be effectively filtered and separated, thus greatly improving the quality of the rainwater. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 - Figure 4 as shown in the figure, a municipal rainwater storage device includes:

[0027] A water storage bucket 3;

[0028] In the middle of the top end of the water storage bucket 3, a connecting pipe 4 is fixedly connected. At the top end of the connecting pipe 4, a diversion pipe 5 is fixedly inserted. On one side of the outer surface of the bottom end of the diversion pipe 5, a sedimentation pipe 6 is installed. A connecting cover 7 is threadedly connected to the outer surface of the sedimentation pipe 6. One end of the diversion pipe 5 away from the connecting pipe 4 is fixedly connected to a filtering box 8. At the top end of the filtering box 8, a collecting mechanism 9 is fixedly inserted.

[0029] The filtering box 8 includes a box body 81, a sealing door 82, an observation window 83 and a filter screen structure 84. The sealing door 82 is movably connected to one end of the box body 81 through a hinge. The observation window 83 is fixedly inserted into one end of the sealing door 82. Both ends of the filter screen structure 84 are respectively fixedly connected to both sides of the inner box wall of the box body 81. The box body 81 is fixedly inserted between the diversion pipe 5 and the collecting mechanism 9.

[0030] The collecting mechanism 9 includes a water receiving hopper 91, a water inlet pipe 92, a limiting ring 93 and a grid plate 94. The water inlet pipe 92 is fixedly connected to the bottom end of the water receiving hopper 91. The limiting ring 93 is fixedly inserted into the inner wall of the water receiving hopper 91. The grid plate 94 is movably inserted into the water receiving hopper 91. The water inlet pipe 92 is fixedly inserted into the top end of the filtering box 8.

[0031] The bottom end of the water storage bucket 3 is fixedly connected to a base 1. Both sides of the bottom end of the base 1 are fixedly connected to support seats 2. One end of the filtering box 8 is fixedly connected to a support frame 10. The end of the support frame 10 away from the filtering box 8 is fixedly connected to the outer surface of the water storage bucket 3.

[0032] From Figure 2 and Figure 3It can be seen that the filter screen structure 84 includes a filter plate 841, a chute 842, a sliding seat 843, a telescopic rod 844, a spring 845 and a net brush 846. The chute 842 is opened in the middle of the top of the filter plate 841. The sliding seat 843 is movably inserted and connected in the chute 842. The telescopic rod 844 is fixedly connected to the top of the sliding seat 843. The net brush 846 is fixedly connected to the top of the telescopic rod 844. The spring 845 is sleeved on the outer surface of the lower part of the telescopic rod 844. The filter plate 841 is obliquely and fixedly connected to the inner walls of both sides of the box body 81.

[0033] As can be seen from the above, the condition on the filter plate 841 can be observed through the observation window 83. When there are too many impurities on the filter plate 841, the sealing door 82 is opened. The staff holds the middle of the net brush 846 and presses the net brush 846 downward. The net brush 846 pushes the telescopic rod 844 to contract, so that the two ends of the net brush 846 are attached to the top of the filter plate 841 downward. The net brush 846 is pulled, so that the sliding seat 843 slides in the chute 842, so that both sides of the net brush 846 clean both sides of the top of the filter plate 841.

[0034] Preferably, the spring 845 is fixedly connected between the sliding seat 843 and the telescopic rod 844, and both bottom sides of the net brush 846 are closely attached to the top of the filter plate 841.

[0035] As can be seen from the above, by setting the spring 845, it is convenient for the net brush 846 to reset.

[0036] Embodiment 2:

[0037] Reference Figure 1 and Figure 4 As shown, the lower part of the water receiving hopper 91 is provided with a conical structure, and the bottom end of the grid plate 94 is closely attached to the limiting ring 93.

[0038] As can be seen from the above, the impurities can be intercepted through the grid plate 94 to prevent the impurities from blocking the device. When collecting rainwater, the rainwater is first filtered through the grid plate 94, and the filtered rainwater is introduced into the box body 81 through the water inlet pipe 92. The grid plate 94 is pulled, and the grid plate 94 is separated from the water receiving hopper 91, so that the impurities on the grid plate 94 can be cleaned. The limiting ring 93 can limit the grid plate 94, and the limiting ring 93 is used to support the grid plate 94, improving the stability of the grid plate 94.

[0039] Working principle: Rainwater is filtered through the grid plate 94 and introduced to the lower part of the water receiving hopper 91, and then introduced into the box body 81 through the water inlet pipe 92 fixedly connected to the water receiving hopper 91. It is filtered by the filter plate 841 in the box body 81. The filtered impurities are introduced into the connecting pipe 4 through the diversion pipe 5 and then introduced into the water storage bucket 3 through the connecting pipe 4 for water storage. During the diversion process, the impurities settle downward due to their weight, so that the impurities are introduced into the sedimentation pipe 6. Turn the connecting cover 7 to make the connecting cover 7 detach from the sedimentation pipe 6, so that the impurities in the sedimentation pipe 6 can be exported. The condition on the filter plate 841 can be observed through the observation window 83. When there are too many impurities on the filter plate 841, open the sealing door 82. The staff holds the middle of the wire brush 846 and presses the wire brush 846 downward. The wire brush 846 pushes the telescopic rod 844 fixedly connected to it to contract. At the same time, the telescopic rod 844 will squeeze the spring 845, so that the two ends of the wire brush 846 fit downward against the top of the filter plate 841. Pull the wire brush 846 to make the sliding seat 843 slide in the sliding groove 842, so that both sides of the wire brush 846 clean both sides of the top of the filter plate 841, and the impurities on the top of the filter plate 841 are moved to the sliding groove 842 by the push of the wire brush 846, which is convenient for cleaning the filter plate 841. Pull the grid plate 94 to make the grid plate 94 detach from the water receiving hopper 91, so that the impurities on the grid plate 94 can be cleaned.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
