Description

Technical Field

[0001] This utility model belongs to the field of dust control technology, and in particular relates to a water supply device for a construction site spraying system. Background Technology

[0002] Construction site fencing with sprinklers is a common method for controlling dust at construction sites. It involves setting up sprinkler systems to create a wide-coverage, high-intensity water curtain around the construction site, trapping dust particles and preventing them from being stirred up. According to the requirements of the Urban and Rural Construction Bureau, mist sprinklers should be installed near construction site fencing, around foundation pits, and around buildings. Construction sites should maintain an effective sprinkler head utilization rate of over 95%. Most construction sites use tap water as the primary water source for sprinkler systems.

[0003] On-site atomizing sprinkler systems are generally required to remain operational 24 hours a day during construction. As required by environmental protection authorities, the atomizing sprinkler system is continuously installed around the perimeter of the construction site enclosure. When the construction area is large, a greater number of atomizing nozzles are used. Calculations show that with a single atomizing nozzle having a flow rate of 0.8 L / min, if the sprinkler system uses 400 nozzles, the flow rate would be 320 L / min = 19.2 m³. 3 / h, which means a daily water consumption of 460 cubic meters during peak periods. If the water used for this atomizing spray is supplied by municipal water, the cost would be extremely high. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, solve or at least alleviate the problem of the extremely high cost of using municipal water supply for sprinkler systems, and provide a water supply device for sprinkler systems on construction sites.

[0005] This utility model is achieved through the following technical solution:

[0006] A water supply device for a construction site sprinkler system includes a water supply tank. The inlet of the water supply tank is connected to a dewatering well via a water pump, and the outlet of the water supply tank is connected to a water supply pipe via a water pump. The water supply pipe is connected to the inlet of the sprinkler system. The water supply pipe is equipped with an overflow pipe. The end of the overflow pipe away from the sprinkler system is connected to the water supply tank. The overflow pipe is used to return water in the water supply pipe to the water supply tank when the water supply pressure of the sprinkler system is too high.

[0007] To further realize this utility model, the following technical solutions may be preferred:

[0008] Preferably, the water supply pumps are two pumps connected in parallel.

[0009] Preferably, the water supply tank is connected to at least two rainwater wells.

[0010] Preferably, one end of the overflow pipe is connected to the water supply pipe, and the other end is equipped with an overflow control component;

[0011] The overflow control component includes a drain pipe and a pressure plate. The upper end of the drain pipe is connected to the overflow pipe and the lower end is connected to the water supply tank. The pressure plate is axially sealed and slidably disposed inside the overflow pipe. The pressure plate is located on the side of the drain pipe closer to the sprinkler system. A spring is provided between the pressure plate and the overflow pipe. The spring drives the pressure plate to move away from the drain pipe.

[0012] Preferably, the overflow control assembly further includes a positioning mechanism, which includes a positioning plate, a guide rod, and a stop. The positioning plate is slidably disposed inside the overflow pipe and located on the side of the drain pipe away from the pressure plate. The guide rod is coaxially disposed inside the overflow pipe, with one end fixedly connected to the pressure plate and the other end extending outward through the positioning plate. The stop is fixedly disposed at the end of the guide rod away from the pressure plate.

[0013] Preferably, the spring is slidably fitted onto the guide rod, with both ends of the spring abutting against the pressure plate and the positioning plate, respectively.

[0014] Preferably, the positioning mechanism further includes a positioning sleeve, one end of which is fixedly connected to the positioning plate and the middle part is threaded onto the end of the overflow pipe.

[0015] Preferably, the overflow control assembly further includes an adjustment mechanism, which includes an adjustment plate and an adjustment sleeve. The adjustment plate is slidably fitted onto the guide rod and located between the positioning plate and the stop block. One end of the adjustment sleeve is fixedly connected to the adjustment plate, the middle part is threaded onto the positioning sleeve, and the other end extends outward.

[0016] The beneficial effects of this utility model through the above technical solution are:

[0017] This invention uses groundwater as the water inlet, which can satisfy both the dewatering of the foundation pit and the dust suppression by watering on site, greatly reducing the cost of municipal water use.

[0018] In addition, this utility model is also equipped with an overflow pipe. When the pressure in the spray system is too high, the water flows back from the overflow pipe to the water supply tank. This not only avoids the pipe from breaking and the atomizing nozzle from being damaged due to excessive pressure in the spray system, but also saves water. Attached Figure Description

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Example 1:

[0027] like Figures 1-3 As shown, a water supply device for a construction site sprinkler system includes a water supply tank 1. The inlet of the water supply tank 1 is connected to a dewatering well via a water pump. The outlet of the water supply tank 1 is connected to a water supply pipe 2 via a water supply pump 5. The water supply pipe 2 is connected to the inlet of the sprinkler system 4. The water supply pipe 2 is equipped with an overflow pipe 3. The end of the overflow pipe 3 away from the sprinkler system 4 is connected to the water supply tank 1. The overflow pipe 3 is used to return the water in the water supply pipe 2 to the water supply tank 1 when the water supply pressure of the sprinkler system 4 is too high.

[0028] This invention uses groundwater as the water inlet, which can satisfy both the dewatering of the foundation pit and the dust suppression by watering on site, greatly reducing the cost of municipal water use.

[0029] Meanwhile, when the pressure inside the spray system 4 is too high, water flows back from the overflow pipe 3 to the water supply tank 1, which not only prevents the pipeline from breaking and the atomizing nozzle from being damaged due to excessive pressure in the spray system 4, but also saves water.

[0030] To ensure reliability during use, two water pumps 5 are installed in parallel, and the number of dewatering wells connected to the water supply tank 1 is no less than two.

[0031] like Figure 4 As shown, in order to optimize the product structure, in this embodiment, one end of the overflow pipe 3 is connected to the water supply pipe 2, and the other end is equipped with an overflow control component.

[0032] The overflow control assembly includes a drain pipe 6 and a pressure plate 7. The upper end of the drain pipe 6 is connected to the overflow pipe 3 and the lower end is connected to the water supply tank 1. The pressure plate 7 is axially sealed and slidably disposed inside the overflow pipe 3. The pressure plate 7 is located on the side of the drain pipe 6 closer to the sprinkler system 4. A spring 14 is provided between the pressure plate 7 and the overflow pipe 3. The spring 14 drives the pressure plate 7 to move away from the drain pipe 6.

[0033] When the pressure inside the water supply pipe 2 is high, the water flow drives the pressure plate 7 to move horizontally towards the drain pipe 6. When the pressure plate 7 moves to the point where the drain pipe 6 connects with the overflow pipe 3, the water in the water supply pipe 2 flows back to the water supply tank 1 through the drain pipe 6.

[0034] To adjust the position of the overflow control component within the overflow pipe 3, the overflow control component also includes a positioning mechanism. The positioning mechanism includes a positioning plate 8, a guide rod 9, and a stop block 10. The positioning plate 8 is slidably disposed within the overflow pipe 3 and located on the side of the drain pipe 6 away from the pressure plate 7. The guide rod 9 is coaxially disposed within the overflow pipe 3. One end of the guide rod 9 is fixedly connected to the pressure plate 7, and the other end extends outward through the positioning plate 8. The stop block 10 is fixedly disposed at the end of the guide rod 9 away from the pressure plate 7. The spring 14 is slidably sleeved on the guide rod 9, and both ends of the spring 14 abut against the pressure plate 7 and the positioning plate 8, respectively. The positioning mechanism also includes a positioning sleeve 11. One end of the positioning sleeve 11 is fixedly connected to the positioning plate 8, and the middle part is threadedly sleeved on the end of the overflow pipe 3.

[0035] In order to adjust the elastic force of the spring 14, the overflow control assembly also includes an adjustment mechanism, which includes an adjustment plate 12 and an adjustment sleeve 13. The adjustment plate 12 is slidably fitted onto the guide rod 9 and located between the positioning plate 8 and the stop block 10. One end of the adjustment sleeve 13 is fixedly connected to the adjustment plate 12, the middle part is threaded onto the positioning sleeve 11, and the other end extends outward.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
