Description

Technical fields:

[0001] This utility model relates to a rainwater collection device, specifically a clean rainwater collection component installed on the top of a domed storage tank. Background technology:

[0002] In the field of effective utilization of natural resources, rainwater is a type of water resource that can be recycled and reused. Currently, some rainwater harvesting devices have been developed, mainly focusing on infiltration collection in roads and grasslands, shed-type collection at bus stops, and collection on building rooftops.

[0003] In industries such as petroleum and chemical processing, there are many large storage tanks. Large domed storage tanks have a large roof area, resulting in high area utilization for rainwater collection and a large volume of rainwater collected. However, rainwater collection devices for these large storage tanks have not yet been developed. Furthermore, during periods of drought, dust easily accumulates on the roofs of large storage tanks. When collecting rainwater, this dust is also collected, turning the rainwater into wastewater and negating the purpose of collecting clean rainwater. Summary of the Invention:

[0004] In response to the technical problems mentioned in the background above, this utility model provides a clean rainwater collection component for the top of a dome-shaped storage tank, which can automatically flush away the dust deposited on the top of the dome-shaped storage tank at the beginning of rain and then collect clean rainwater, without the need for manual control and operation.

[0005] Technical solution: A clean rainwater collection assembly for the top of an arched storage tank, comprising a enclosure, and several filters disposed on the inner side of the enclosure and drain pipes, sludge collection bins, lifting lugs, springs, sliding sleeves, sludge discharge cylinders, plugs, and supports.

[0006] The enclosure plate is welded to the edge of the tank's dome, forming a ring to create a dike to block rainwater; the bottom of the enclosure plate has several equally spaced notches in the circumferential direction.

[0007] The number of drainage pipes corresponds to the number of openings in the enclosure. The upper part is inserted into the middle of the enclosure, and the lower part is connected to the rainwater storage tank or the clean water pool.

[0008] The number of openings in the sludge collection bin corresponds to the number of openings in the enclosure. It is made of steel plates and steel pipes welded into an irregular cylindrical shape and welded to seal the outside of the openings in the enclosure. The side openings are connected to the openings. A sleeve is provided at the bottom of the sludge collection bin.

[0009] The filter screen is installed inside the opening of the enclosure, covering the drain pipe and the inlet of the sludge collection bin;

[0010] The sliding sleeve is configured as a cylindrical copper alloy material with a closed top, and is installed in the sleeve at the bottom of the sludge collection bin. Its outer diameter is in clearance fit with the inner hole of the sleeve. The upper side of the sliding sleeve has two water inlet holes, and the lower outer wall is machined with external threads.

[0011] Two lifting lugs are provided for each group, which are respectively welded to the inner side of the top plate of the sludge collection bin and the top of the sliding sleeve;

[0012] The spring is a tension spring, with both ends connected to a pair of lugs to stretch the sliding sleeve;

[0013] The sewage discharge cylinder is cylindrical and connected to the sliding sleeve at the lower part of the sewage collection bin; a connecting pipe with internal threads is provided at the upper part of the sewage discharge cylinder, which is connected to the external threads at the lower part of the sliding sleeve; a sewage discharge pipe is provided at the lower part of the sewage discharge cylinder.

[0014] The bracket is welded to the side wall of the storage tank, and its position corresponds to the lower part of the sewage pipe. The drain pipe is welded to the outside as an auxiliary support.

[0015] The plunger is a small cylinder with a chamfered upper part and welded to the bracket at the lower part; the axis of the plunger is coaxial with the drain pipe of the drain cylinder, and the outer diameter of the plunger is clearance-fitted with the inner hole of the drain pipe.

[0016] Furthermore, the axial length of the sliding sleeve and the drain cylinder is matched with the installation height of the plug as follows: when the drain cylinder is empty and rises to its highest point, the water inlet hole at the top of the sliding sleeve is exposed in the sludge collection chamber, and the drain pipe at the bottom of the drain cylinder leaves the plug and exposes the lower drain channel; when the drain cylinder is filled with water and descends to its lowest point, the drain pipe at the bottom of the drain cylinder is inserted into the plug, and at the same time, the water inlet hole at the top of the sliding sleeve enters the sleeve at the bottom of the sludge collection chamber, blocking the upper water inlet channel.

[0017] Furthermore, the tension of the spring is set such that the spring tension at the highest point of the drain pipe is greater than the weight of the sliding sleeve and the drain pipe; and the spring tension at the lowest point of the drain pipe is less than the weight of the sliding sleeve, the drain pipe, and the drain pipe when it is filled with 80% to 90% water.

[0018] Furthermore, in order to ensure that the water inflow rate of the sewage discharge cylinder is greater than the water outflow rate, the cross-section of the sewage pipe at the bottom of the sewage discharge cylinder is set to be smaller than that of the water inflow channel at the top of the sliding sleeve, and the water level rise rate in the sewage discharge cylinder is controlled by setting the ratio between the size of the sewage pipe inner hole and the size of the water inflow hole.

[0019] Furthermore, in order to improve the sewage collection effect, the side opening of the sewage collection chamber is designed to be an open shape that is larger on the outside and smaller on the inside.

[0020] Furthermore, to prevent dust from accumulating in the sewage, the bottom surface of both the sludge collection chamber and the bottom surface of the sewage discharge pipe are designed to be conical.

[0021] Compared with existing background technologies, the above-described at least one technical solution adopted in one or more embodiments of this specification can achieve the following beneficial effects:

[0022] First, the clean rainwater collection component can make full use of the large top area of ​​the existing dome tank to collect rainwater without the need for additional canopy structures, thus saving manufacturing costs. Second, the clean rainwater collection component can automatically flush away the dust deposited on the top of the dome tank at the beginning of rainfall, and then collect clean rainwater. Finally, the clean rainwater collection component automatically discharges wastewater and collects clean rainwater without the need for manual control or operation.

The same reference numerals in the drawings denote elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0036] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this utility model.

[0037] like Figures 1 to 8 As shown, a clean rainwater collection assembly for the top of a domed storage tank includes a enclosure 1, and several filter screens 2 disposed inside the enclosure 1 and drain pipes 3 disposed outside the enclosure 1, a sludge collection bin 4, a lifting lug 5, a spring 6, a sliding sleeve 7, a sludge discharge cylinder 8, a plug 9, and a bracket 10.

[0038] like Figures 1-4 As shown, the enclosure 1 is welded to the edge of the tank arch 12 to form a dam to block rainwater; the bottom of the enclosure 1 has several openings 101 evenly distributed in the circumferential direction to discharge sewage.

[0039] like Figures 1-4 As shown, the number of drainage pipes 3 corresponds to the number of openings 101 in the enclosure 1. The upper part is inserted into the middle of the enclosure 1, and the lower part is connected to the rainwater storage tank or clean water pool, which is used to discharge the clean water accumulated in the enclosure 1 to a certain height into the rainwater storage tank or clean water pool.

[0040] like Figure 5 and Figure 6As shown, the number of openings 101 in the sludge collection chamber 4 corresponds to the number of openings 101 in the surrounding plate 1. It is an irregularly shaped cylindrical assembly welded from steel plates and pipes, and welded to the outside of the openings 101 in the surrounding plate 1. The side openings communicate with the openings 101 for discharging wastewater containing dust. A sleeve 401 is installed at the bottom of the sludge collection chamber 4 for installing a sliding sleeve 7. To improve the wastewater collection effect, the side openings of the sludge collection chamber 4 are designed to be wider on the outside and narrower on the inside. To prevent dust deposition in the wastewater, the bottom surface of the sludge collection chamber 4 is designed to be conical.

[0041] like Figures 1-4 As shown, the filter screen 2 is set inside the opening 101 of the enclosure 1, covering the inlet of the drain pipe 3 and the sludge collection bin 4, in order to prevent large debris such as leaves from entering the drain pipe 3 or the sludge collection bin 4 and causing blockage.

[0042] like Figure 7 As shown, the sliding sleeve 7 is a cylindrical shape made of copper alloy with a closed top, and is installed in the sleeve 401 at the bottom of the sludge collection bin 4. Its outer diameter is in clearance fit with the inner hole of the sleeve 401, and it can slide up and down. The upper side of the sliding sleeve 7 has two water inlet holes 701 for water intake, and the lower outer wall is machined with external threads for connecting the sewage discharge cylinder 8.

[0043] like Figure 3 and Figure 4 As shown, each set of lifting lugs 5 is provided with two, which are welded to the inner side of the top plate of the sludge collection bin 4 and the top of the sliding sleeve 7 respectively, for installing the spring 6.

[0044] like Figure 3 and Figure 4 As shown, spring 6 is a tension spring, with both ends connected to a pair of lifting lugs 5, which raise the sliding sleeve 7. The tension of spring 6 is set as follows: when the drain pipe 8 is at its highest position, the tension of spring 6 is greater than the weight of the sliding sleeve 7 and the drain pipe 8; when the drain pipe 8 is at its lowest position, the tension of spring 6 is less than the weight of the sliding sleeve 7, the drain pipe 8, and the drain pipe 8 when it is filled with 80% to 90% water.

[0045] like Figure 8 As shown, the sewage discharge cylinder 8 is cylindrical and connected to the sliding sleeve 7 at the lower part of the sewage collection chamber 4. A connecting pipe 801 with internal threads is installed at the upper part of the sewage discharge cylinder 8, which engages with the external threads at the lower part of the sliding sleeve 7. A sewage discharge pipe 802 is installed at the lower part of the sewage discharge cylinder 8 for discharging sewage from the cylinder. To prevent dust accumulation in the sewage, the bottom surface of the sewage discharge cylinder 8 is tapered. To ensure that the inflow rate of the sewage discharge cylinder 8 is greater than the outflow rate, the cross-section of the inner hole of the sewage discharge pipe 802 at the lower part of the sewage discharge cylinder 8 is set to be smaller than the inflow hole 701 channel at the upper part of the sliding sleeve 7. The rising speed of the water level in the sewage discharge cylinder 8 is controlled by setting the ratio between the inner hole of the sewage discharge pipe 802 and the inflow hole 701.

[0046] like Figure 3 and Figure 4 As shown, the bracket 10 is welded to the side wall 11 of the storage tank, and its position corresponds to the lower part of the sewage pipe 8. The drain pipe 3 is welded to the outside as an auxiliary support.

[0047] like Figure 3 and Figure 4 As shown, the plug 9 is a small cylinder with a chamfered upper part and welded to the bracket 10 at the lower part; the axis of the plug 9 is coaxial with the sewage pipe 802 of the sewage cylinder 8, and the outer diameter of the plug 9 is clearance-fitted with the inner hole of the sewage pipe 802, which is used to slowly discharge water when blocking the sewage cylinder 8.

[0048] The axial length of the sliding sleeve 7 and the drain cylinder 8 is matched with the installation height of the plunger 9 as follows: when the drain cylinder 8 is empty and rises to its highest point, the water inlet 701 at the top of the sliding sleeve 7 is exposed in the sludge collection chamber 4, and the drain pipe 802 at the bottom of the drain cylinder 8 leaves the plunger 9 and exposes the lower drain channel. Figure 3 As shown. When the water level in the drain cylinder 8 drops to its lowest point, the drain pipe 802 at the bottom of the drain cylinder 8 is inserted into the plug 9, and at the same time, the water inlet 701 at the top of the sliding sleeve 7 enters the sleeve 401 at the bottom of the sludge collection bin 4, blocking the upper water inlet channel, as shown. Figure 4 As shown.

[0049] like Figures 1-4 As shown, the specific implementation principle of this utility model is as follows:

[0050] When it doesn't rain for several days, the water in the drain pipe 8 gradually empties. Because the tension of the spring 6 is greater than the weight of the sliding sleeve 7 and the drain pipe 8 itself, under the action of the spring 6, the drain pipe 8 rises to its highest point. The water inlet 701 at the top of the sliding sleeve 7 is exposed in the sludge collection chamber 4, and the drain pipe 802 at the bottom of the drain pipe 8 leaves the plug 9, exposing the lower drain channel. Figure 1 and Figure 3 As shown.

[0051] When it starts to rain, the rainwater washes away the dust deposited on the surface of the tank dome 12. Wastewater flows down the tank dome 12 to the surrounding plate 1, enters the various sludge collection chambers 4 through several openings 101 in the surrounding plate 1, and then enters the sludge discharge cylinder 8 through the water inlet 701 at the top of the sliding sleeve 7. Finally, it is discharged through the sludge discharge pipe 802 at the bottom of the sludge discharge cylinder 8. Because the inner cross-section of the sludge discharge pipe 802 at the bottom of the sludge discharge cylinder 8 is smaller than the channel of the water inlet 701 at the top of the sliding sleeve 7, and this is done in a certain proportional relationship (i.e., more water enters than exits), the water level in the sludge discharge cylinder 8 begins to rise slowly, and the weight of the water in the sludge discharge cylinder 8 begins to increase. As the pressure gradually increases, the tension spring 5 begins to gradually decrease; after the initial rainwater washes away the dust from the surface of the tank dome 12, the water level in the drain pipe 8 approaches 80% to 90%, and the drain pipe 8 descends to its lowest point. The drain pipe 802 at the bottom of the drain pipe 8 is inserted into the plug 9, blocking the lower drainage channel. At the same time, the water inlet 701 at the top of the sliding sleeve 7 enters the sleeve 401 at the bottom of the sludge collection bin 4, blocking the upper water inlet channel, thus closing the entire drain channel; the rainwater level blocked by the enclosure 1 rises, reaching the inlet of the drain pipe 3, and is collected through the drain pipe 3 to the rainwater storage tank or clear water pool, such as... Figure 2 and Figure 4 As shown.

[0052] During the rain, because the outer diameter of the sliding sleeve 7 and the inner hole of the lower sleeve 401 of the sludge collection chamber 4 are in clearance fit, and the inner hole of the lower drain pipe 802 of the drain cylinder 8 and the outer diameter of the plug 9 are also in clearance fit, the water that slowly seeps out through the lower drain pipe 802 is replenished by the water that seeps in from the upper part, so the water level in the drain cylinder 8 remains basically unchanged, and the drain cylinder 8 remains stationary at the lowest point.

[0053] When the rain stops, there is no water replenishment at the top of the drain pipe 8, and the water in the drain pipe 8 slowly seeps out and is discharged. When a certain amount of water is discharged from the drain pipe 8, the drain pipe 8 begins to rise under the pulling force of the spring 6. The drain pipe 802 at the bottom of the drain pipe 8 leaves the stopper 9 and exposes the lower channel. The water in the drain pipe 8 is quickly emptied and rises to the highest point.
