Description

Technical Field

[0001] The present invention relates to garden pond management, in particular to a drainage device for municipal gardens. Background Art

[0002] In municipal gardens, one or more water structures are generally built. These water structures are ponds, pools or water storage areas. The water stored in these water storage areas is generally used for garden water, that is, water for irrigation and storage. However, in garden ponds, pools or water storage areas, there are many branches, fallen leaves and floating garbage and sediment garbage blown in from the environment in the upper layer of the water body. These garbage are difficult to collect and treat in the water body. The floating garbage affects the overall aesthetic effect of the garden, and the sediment garbage affects the drainage system of the garden water body.

[0003] In the current drainage systems in garden water areas, many of them use immersed pipe drainage, that is, immersed pipes and filter grilles are pre-buried at the low water level of the water body, and drainage is carried out by controlling the opening of the immersed pipes to control the water level and meet the water needs of the garden water area. However, as mentioned above, the garden water area contains a large amount of garbage, which will clog the pre-buried immersed pipes and filter grilles, resulting in slow water discharge speed, and then slow water level control speed; and the current garden water drainage system is not intelligent enough, and the drainage speed and accuracy are insufficient, which also leads to insufficient water level control accuracy.

[0043] like Figure 17 As shown, the water-blocking mechanism 10 includes a hydraulic cylinder 101 and a water-blocking plate 102. The hydraulic cylinders 101 are fixedly connected to the left side wall of the blocking dam body 3 at a position above its water leakage hole structure.

[0044] like Figure 17-18 As shown, the filtering mechanism 11 includes a filter cabin 111, a cover plate 112, a discharge pipe 113 and a water filter screen 114.

The discharged water will push the surrounding floating garbage to the left in the reservoir 1, so that the floating garbage flows to the area in the guide pool 2, so that when the water filtering mechanism 6 is draining, the floating garbage and sediment garbage can be discharged in a concentrated manner; especially when the water level of the reservoir 1 is adjusted within a small range, the alluvial mechanism 12 can be controlled in advance to operate so that the floating garbage is concentrated in the guide pool 2, so that the floating garbage can be discharged in a concentrated manner, further accelerating the drainage speed of the water body containing floating garbage in the reservoir 1.

[0046] Example 2, as Figures 1-19As shown, the assembly method of the municipal garden drainage device is as follows: after the water reservoir 1 is built in the garden, the guide pool 2 is built on the left side of the water reservoir 1, the blocking dam body 3 is installed at the guide pool 2, the water filtering mechanism 6 is assembled between the displacement frame 5 and the blocking dam body 3, the debris removal mechanism 7, the debris pushing mechanism 8 and the recoil mechanism 9 are installed at the displacement frame 5 and the water filtering mechanism 6, and the water blocking mechanism 10 and the filtering mechanism 11 are installed at the blocking dam body 3; a water level gauge is installed in the water storage; the municipal garden drainage device is connected to the external control room for power supply, signal and control lines, so that the external control room can monitor and control the municipal garden drainage device in real time, and adjust the water level and clean the water body in time; the docking Valve 66 is connected to the external temporary storage tank, water area pipeline and external leakage pipe, so that the high-purity water in the upper layer of the water reservoir 1 discharged from the docking valve 66 can be used for emergency reserve water for the garden, and for irrigation water for landscaping; the drainage compartment 71 is connected to the external impurity collection box; in addition, if there are multiple municipal garden drainage devices in the garden, the water channels of multiple water reservoirs 1 can be interconnected through the part connected to the external water distribution pipe through the discharge pipe 113, and an electric control valve system can be installed at the part connected to the external water distribution pipe to control the water channel interconnection, so that the water reservoir 1 in the water-rich area can replenish water in the water-scarce area, thereby maintaining water balance between the multiple water reservoirs 1 in the garden.

[0047] The water storage method of the municipal garden drainage device includes the following steps: controlling the water blocking mechanism 10 to close the drainage hole structure of the blocking dam body 3; controlling the first electric movable pair 4 to drive the displacement frame 5 through its movable part to move the water filtering mechanism 6 upward, so that the lower side of the water filtering chamber of the water filtering mechanism 6 is higher than the required water storage level; and then supplying and storing water into the water reservoir 1 of the municipal garden drainage device from the outside.

[0048] The water level control method of the municipal garden drainage device has two methods for controlling the water level in the water reservoir 1. One is to control the water level through the water filter mechanism 6: the water level detected by the water level gauge installed in the water reservoir 1 can be controlled by the external control room to operate the first electric movable pair 4, so that the displacement frame 5 drives the water filter cabin of the water filter mechanism 6 to move downward, so that the lower side of the water filter cabin is at the water level height required to be controlled. At this time, the water in the water reservoir 1 will be discharged from the water filter cabin through the filter plate 63 to the water collecting bucket 64. At this time, the docking valve 66 is opened, and the water in the water collecting bucket 64 will be discharged to the outside through the diversion pipe 65 and the docking valve 66. The water discharged from the docking valve 66 can be discharged to the external temporary storage pool, water area pipeline or external leakage pipe according to needs, so as to make full use of the pure water in the upper layer of the water reservoir 1; the second is to control the water level through the water blocking mechanism 10: when controlling the water level, If it is necessary to drain the water at the same time, the operation of the hydraulic cylinder 101 can be controlled, and according to the sediment situation in the lower layer of the water reservoir 1, the operation number and operation height of the hydraulic cylinder 101 can be controlled to make different numbers of water blocking plates 102 move upward by a controlled distance, so that the drain outlet structure of the blocking dam body 3 is opened in the required number and the required opening area. At this time, the water in the water reservoir 1 will be discharged from the drain hole structure of the blocking dam body 3, and the sediment garbage in the lower layer of the water body will also be discharged. Then, while controlling the water level, the lower sediment garbage in the water reservoir 1 is also preliminarily discharged. The water containing sediment discharged from the blocking dam body 3 will be filtered by the filtering mechanism 11 and then discharged. The water discharged from the filtering mechanism 11 can be discharged to the external sewage pipe or water distribution pipe according to the water demand and the water quality of the discharged water, so that the discharged water can compensate other water reservoirs 1 or be directly discharged into the garden sewage pipe network.

[0049] The municipal garden drainage device controls the water level through the water filter mechanism 6 to process the floating garbage in the water body: when the water is discharged from the water filter chamber, the floating garbage on the upper layer of the reservoir 1 will also flow into the water filter chamber. At this time, the water filter plate 63 will intercept the floating garbage. At this time, the third electric moving pair 81 and the fourth electric moving pair 91 can be controlled to move back and forth. The third electric moving pair 81 and the fourth electric moving pair 91 will drive the pushing mechanism 8 and the recoil mechanism 9 to move back and forth. The pushing chamber 82 will push the floating garbage into the water chamber 6. 1 is pushed to a position close to the debris discharge compartment 71. At this time, the second electric moving pair 72 on the side adjacent to the pushing compartment 82 can be controlled to drive the baffle 73 connected thereto to move upward, so that the debris discharge compartment 71 at this position is opened. At this time, the pushing compartment 82 will continue to push the floating garbage into the debris discharge compartment 71 at this position. At the same time, the water flow will also be discharged from the debris discharge compartment 71 at this position to the left position of the barrier dam body 3. The water flow will also directly flush the floating garbage in the debris discharge compartment 71 at this position and flush it to the connected external debris discharge compartment 71. The debris collection box is then operated, and then when the third electric moving pair 81 and the fourth electric moving pair 91 continue to operate in the reverse direction, the second electric moving pair 72 is controlled to drive the baffle 73 to move downward to re-close the debris discharge compartment 71 at that position, until the debris compartment 82 moves to the position of the debris discharge compartment 71 on the other side, and the floating garbage is discharged as described above; and when the debris compartment 82 moves back and forth, the first water pump 93 can be turned on, and the first water pump 93 will extract water from the diversion pipe 65 through the delivery pipe 94 and the extraction pipe 95, and the water is pumped out through the first water pump 93 The drainage end of the filter plate is flushed from left to right in the opposite direction, so that the small-volume floating garbage stuck at the filter plate is flushed into the pipe structure of the pushing chamber 82 and discharged into the filter chamber 111 through the drainage pipe 83 and the discharge pipe 84; in this way, when the water level in the water reservoir 1 is controlled, the water filtering performance of the water chamber 61 and the water filter plate 63 can be maintained by the pushing mechanism 8 and the backwash mechanism 9, thereby preventing the floating garbage from clogging the water filter plate 63, ensuring the reliability of water filtering during drainage, and thus maintaining the drainage speed and efficiency, while cleaning the upper layer of the water body.

[0050] The municipal garden drainage device controls the water level through the filtering mechanism 11, and processes the sediment garbage in the water body in the following manner: the sediment garbage contained in the water discharged from the drainage hole structure of the blocking dam body 3 will be intercepted and filtered by the water filtering net 114, so that the water body is discharged from the discharge pipe 113; the detachable cover 112 can be opened to collect the sediment garbage in the filter cabin 111 in a centralized manner, so that the sediment in the water reservoir 1 can be quickly collected in a centralized manner without the need to empty the water in the water reservoir 1.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
