Description

Technical Field

[0001] This utility model relates to the field of construction technology in mountainous areas, and more specifically, to a water collection device for mountain camps in seasonal river areas. Background Technology

[0002] The Lower Kafue Gorge power transmission project in Zambia is a mountainous construction project. Due to the poor road conditions, well drilling equipment cannot reach the site, and the rivers in Zambia are seasonal rivers with dry seasons.

[0003] There are two traditional methods for obtaining water at mountain campsites: (1) Drilling a well to obtain water First, radar equipment is used to locate underground water sources. Then, deep wells are drilled at the water source using well-drilling equipment, and water is extracted by pumping water from the ground. Disadvantages: Well drilling is often restricted by road conditions, making it impossible to carry out due to the inability of drilling equipment to reach the site, and the cost of drilling is relatively high; another disadvantage is that a well may be drilled that has no water, which would increase costs too much since the project is not a very long-term project.

[0004] (2) Water intake from the open river Search for open rivers in the mountains, then build a road between the camp and the open river, and install water pumps in the open river to pump water back to the camp for use; Disadvantages: Water collection from the open river is seasonal. Once the dry season arrives, the open river dries up and water cannot be collected. In addition, a road needs to be built from the camp to the open river to enable water transport, which is costly.

[0005] Based on the above problems, there is an urgent need to improve existing water intake technologies to solve the water intake problem for mountain camps in seasonal river areas, while also reducing water intake costs. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a water intake device for mountain camps in seasonal river areas that has relatively low water intake costs and is easy to construct.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a water intake device for mountain camps in seasonal river areas, including a seepage pit, a submersible pump, a filter cage, a water delivery pipe, a water storage tank, a filter, and a water inlet pipe; The seepage pit is used to collect seepage water as a water source; The submersible pump is installed in the filter cage and then submerged in the seepage pit to provide water intake power. The filter cage is used for preliminary filtration of the seepage water. The submersible pump is connected to a water storage tank via a water delivery pipe, and is used to guide seepage water into the water storage tank for temporary storage. The outlet of the water storage tank is connected to the household water pipe via a filter to provide drinking water to users.

[0008] Preferably, the filter cage is a wire cage, and the wire cage is filled with filter material.

[0009] Preferably, the filter material is charcoal, activated carbon, or ceramsite.

[0010] Preferably, a water level monitoring sensor is installed in the seepage pit, and the water level monitoring sensor is associated with the submersible pump as one of the trigger signals for the submersible pump to start and stop.

[0011] Preferably, the water storage tank is equipped with a level gauge, which is associated with the submersible pump and serves as a second trigger signal for the pump to start and stop.

[0012] Preferably, the filter has a built-in filter element, which is a multi-layer filter element with a composite structure.

[0013] Preferably, the filter element includes at least a physical filtration layer and a membrane separation layer.

[0014] Preferably, the physical filtration layer comprises activated carbon or PP cotton, and the membrane separation layer comprises an RO reverse osmosis membrane or an ultrafiltration membrane.

[0015] Preferably, the seepage pit is located near a seasonal river.

[0016] Preferably, a booster pump is installed between the water storage tank and the water inlet pipe.

[0017] This utility model has substantial features and advancements compared to existing technologies. Specifically, based on the regional factors of seasonal rivers, this utility model sets up seepage pits to accumulate water through the slow seepage capacity of the seepage pits. Then, submersible pumps and filter cages are used to extract water, which is then temporarily stored in a water storage tank. When needed, the water is filtered through a filter before being used in households. This solves the water shortage problem of seasonal rivers. At the same time, the use of water storage tanks to store water avoids the problem of slow seepage from seepage pits and the inability to use water immediately. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, a water intake device for a mountain camp in a seasonal river area includes a seepage pit 1, a submersible pump 2, a filter cage 3, a water delivery pipe 4, a water storage tank 5, a filter 6, and an inlet water pipe 7.

[0023] The seepage pit 1 is used to store seepage water as a water source. Generally, the seepage pit 1 needs to be close to a natural water source, namely near the seasonal river 8 in the area, to obtain water by utilizing the seepage of underground water stored in the seasonal river. Since the seepage pit 1 is all seepage water, the accumulation speed is relatively slow and it cannot be used immediately. Therefore, it also needs to be used in conjunction with water storage facilities.

[0024] The submersible pump 2 is installed in the filter cage 3 and then submerged in the seepage pit 1 to provide water intake power. The filter cage 3 is used for preliminary filtration of the seepage water. In this embodiment, the filter cage 3 is designed as a wire cage and filled with filter material, such as charcoal, activated carbon or ceramsite, for preliminary filtration of the water and adsorption of impurities.

[0025] The submersible pump 2 is connected to the water storage tank 5 through the water supply pipe 4, and is used to guide the seepage water into the water storage tank 5 for temporary storage. The size of the water storage tank 5 can be designed according to the needs of the people using the water.

[0026] The outlet of the water storage tank 5 is connected to the household water pipe 7 through the filter 6 to provide drinking water to users. The filter 6 is a higher-level filter, and the output water generally needs to meet drinking water standards. Therefore, in this embodiment, the filter 6 is a special device with a built-in filter element. The filter element is a multi-layer filter element with a composite structure. The filter element includes at least a physical filtration layer and a membrane separation layer. The physical filtration layer includes activated carbon or PP cotton, and the membrane separation layer includes an RO reverse osmosis membrane or an ultrafiltration membrane.

[0027] When the water storage tank is small and the water pressure it generates is insufficient to provide filtration pressure, a booster pump is installed between the water storage tank and the inlet water pipe.

[0028] To enable the device to operate automatically, in a preferred embodiment, a water level monitoring sensor is installed in the seepage pit, which is associated with the submersible pump as one of the trigger signals for the pump to start and stop; a level gauge is installed in the water storage tank, which is associated with the submersible pump as another trigger signal for the pump to start and stop.

[0029] Its working logic is as follows: when the level gauge detects that the water level in the storage tank is lower than the maximum water level, and at the same time the water level in the seepage pit reaches the pumping water level, it is determined that water can be temporarily drawn and stored, and the submersible pump is started to draw water and store it in the storage tank; when the water level in the storage tank reaches the maximum water level, the submersible pump will no longer be started to draw water, regardless of the water level in the seepage pit; when the water level in the seepage pit is lower than the water drawing water level, the submersible pump will not be started, regardless of whether the water level in the storage tank is at the maximum water level.

[0030] This allows for the most efficient water intake and use. The main purpose of this method is that the seepage rate of the seepage pit is limited, but the seepage is continuous. If no intervention is taken, the seepage pit will stop seeping once it reaches the seepage level, resulting in waste. Therefore, timely pumping out and temporarily storing the seepage water can ensure that the seepage pit continuously produces seepage water, thereby improving the utilization efficiency of the seepage water.

[0031] This scheme was experimentally verified in the Lower Kafue Gorge 330kV power transmission project in Zambia. The project consists of one 48km single-circuit line of 330kV from the Lower Kafue Gorge substation to the Lusa South substation; one 90km single-circuit line of 330kV from the Lower Kafue Gorge substation to the Lusa Kasi substation; one 19km single-circuit line of 330kV from the Kafue West substation to the Lusa Kasi substation; and one 26km double-circuit line of 330kV from the intersection of the Lusa Kasi and Kafue West lines to the Lusa Kasi substation. The total length of the single-circuit line is 153km, the double-circuit line is 26km, and there are 411 towers. In addition, there are 3 substations and 4 bays. The terrain along the route is mostly primitive mountainous terrain with large elevation differences, making the construction conditions complex.

[0032] There is a region called SATA along the construction route, which has a seasonal river. However, the seasonal river dries up during the dry season. The SATA region is located deep in the mountains, and transportation is inconvenient. Well drilling equipment cannot be transported to the site. These problems restrict the project's construction water and domestic water supply.

[0033] The experimental verification and implementation of this patent effectively solved the water problem for employees, and also solved part of the drinking water problem for local residents, greatly improving work efficiency, saving project costs, and ensuring the smooth execution of the project.

[0034] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
