Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological protection, in particular to a device and method for treating light-biological pollution in a tourist cave. BACKGROUND

[0002] A cave is an underground space formed in soluble rock due to karstification. The formation of a cave is a result of long-term erosion of groundwater in a limestone area. Due to the difference in the amount of lime in different parts of the limestone layer, the erosion degree is different, and the soluble rock is gradually dissolved and divided into independent, various, steep and beautiful peaks and strange landscapes of caves, thus forming a karst landscape. Some caves are developed into tourist caves for people to visit.

[0003] Light-biological pollution in a tourist cave has a great destructive effect on the interior landscape of the cave. Due to the introduction of light, various spore plants such as ferns and mosses begin to grow on the calcium carbonate deposits in the cave. When there is light in the cave, spores will germinate and develop, and the root system will penetrate into the calcium carbonate deposits to cause mechanical damage. The secretion of mosses causes chemical damage, and the accumulation of the rotten bodies of generations of mosses on the surface of the landscape makes it black, greatly affecting the viewing effect.

[0004] In order to eliminate light-biological pollution, cold light source lighting is widely used, but the effect is very small. After the tourist cave uses cold light source lighting, mosses still grow on the landscape in the cave, and even weeds grow near the light source, which cannot solve the problem. SUMMARY

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0045] Embodiment 1

[0046] Referring to Figures 1-8 A tourism cave light-biological pollution treatment device and method, comprising:

[0047] A pedestrian passage 1 is used for the access of tourists, and the pedestrian passage 1 is arranged at the exit and entrance of the cave;

[0048] An intercepting assembly is used for intercepting spores, and the intercepting assembly comprises a spraying component and a blowing component. The spraying component comprises a top plate 2, a plurality of water dripping cones 3, a flow guide pipe 4, a plurality of drainage pipes 5 and a plurality of spray heads 6. The top plate 2 is fixedly installed on the top wall of the cave entrance through a filler 12. The plurality of water dripping cones 3 are fixedly installed on the bottom surface of the top plate 2 in a symmetrical and vertical manner, and the tips of the water dripping cones 3 all downwardly point. The flow guide pipe 4 is horizontally arranged at the lower side of the top plate 2 and is connected with the bottom of the top plate 2 through a plurality of support frames. The plurality of drainage pipes 5 are fixedly sleeved on the outer side of the flow guide pipe 4 in a symmetrical manner and are in communication with the inside of the flow guide pipe 4. The plurality of spray heads 6 are fixedly sleeved on the ends of the plurality of drainage pipes 5 away from the flow guide pipe 4 and are in communication with the plurality of drainage pipes 5. When the facility is installed, the length of the equipment is planned according to the specific shape and size of the tourism cave entrance, so that the entire width of the cave entrance is covered.

[0049] Valves 33 are fixedly arranged on the plurality of drainage pipes 5. The valves 33 can control the on-off of the single spray head 6, and the plurality of spray heads 6 and the plurality of water dripping cones 3 are symmetrically distributed to form double water curtains. The purpose of arranging the double water curtains is to improve the air washing capacity of the double water curtains and to ensure that at least one water curtain normally works during maintenance, so that the interception and the maintenance do not interfere with each other.

[0050] A water supply assembly is fixedly connected and in communication with the end of the flow guide pipe 4.

[0051] The blowing component is arranged in the pedestrian passage 1 and the flow direction of the blowing component points to the outside of the cave. The air flow area of the blowing component needs to cover the entire aperture of the pedestrian passage.

[0052] A water collecting tank 7 is arranged at the bottom of the cave entrance, and the pedestrian passage 1 is embedded at the bottom side of the water collecting tank 7.

[0053] The blowing component comprises two blowing ports 8, a direct-current electric fan 9 and an alternating-current electric fan 26, the two blowing ports 8 are arranged on the inner side wall of the pedestrian passage 1 and close to the inside of the cave, and the output ends of the direct-current electric fan 9 and the alternating-current electric fan 26 are fixedly connected with the two blowing ports 8 through a gas conveying pipe 10.

[0054] The front and rear sides of the top plate 2 are vertically fixedly installed with water-shielding eaves 11, and the sides close to each other of the two water-shielding eaves 11 are fixedly attached with flow-guiding and mist-reducing nets 13 for blocking and reducing the water mist from drifting outwards.

[0055] The intercepting assembly is arranged at the entrance and exit of the cave entrance, then the equipment is started to operate, the water supply assembly pumps water, and the water is pressurized and sent into the flow guide pipe 4, then the water body enters the spray head 6 through the drainage pipe 5, and finally is sprayed out by the spray head 6, the sprayed water flow is received by the water droplet cone 3, since the plurality of water droplet cones 3 are arranged at the bottom of the top plate 2 with the sharp heads downward, the water body drops along the sharp head, the plurality of water droplet cones are arranged in a staggered manner, and finally the water body that drops forms a water curtain to water seal the entrance and intercept the spores.

[0056] Meanwhile, the blowing component operates to blow air to the outside of the cave entrance through the blowing port 8, so as to drive away the spores in the pedestrian passage 1 and avoid the spores from entering the cave, when the tourists enter the cave and pass through the pedestrian passage 1, the blowing component blows off the spores adhered to the human body, avoids the spores from entering the inside of the cave with the tourists, and comprehensively intercepts the spores.

[0057] In the above manner, the water curtain is formed by the spraying component, and the ventilation of the pedestrian passage 1 by the blowing component, so as to form a comprehensive protection layer for the cave entrance, which can effectively block the spores from entering the cave, and meanwhile does not interfere with the normal operation of the cave.

[0058] Compared with the cold light source technology, the method of intercepting the spores from entering the inside of the cave can fundamentally solve the problem of light-biological pollution, and has a better effect.

[0059] Embodiment 2: Different from embodiment 1 is that the water supply assembly comprises a gas pressure water storage tank 14 and a water pump component, the gas pressure water storage tank 14 is symmetrically provided with a water inlet pipe 15 and a water outlet pipe 16 at the bottom end, the water inlet pipe 15 is fixedly connected with the output end of the water pump component through a first water pipe 17 in a conductive mode, the flow guide pipe 4 is fixedly connected with the water outlet pipe 16 through a second water pipe 18 in a conductive mode, the space inside the gas pressure water storage tank 14 is filled with gas at the upper side and water at the lower side, has a stable pressure, and can continue to supply water to the spraying component for a short time when the power is suddenly cut off, so as to ensure the normal operation of the equipment and gain time for adjusting the circuit connection.

[0060] The water pump component input end is fixedly connected with the filter tank 20 through the third water pipe 19. The filter tank 20 is fixedly sleeved with the filter screen 21. The filter tank 20 input end is fixedly connected with the water collecting tank 7 through the backflow pipe 22.

[0061] When the water is sprayed to form a water curtain and finally falls into the water collecting tank 7, the water pump component pumps water from the filter tank 20 through the third water pipe 19. Under the pumping action, the water flows from the water collecting tank 7 into the backflow pipe 22, flows into the filter tank 20 through the backflow pipe 22, is filtered by the filter screen 21, is pumped by the water pump component, and is finally sent to the spraying component to form a water curtain and flows into the water collecting tank 7 to realize the recycling of the water body.

[0062] The water pump component includes a direct current electric water pump 23, an alternating current electric water pump 24 and two check valves 25. The input ends of the direct current electric water pump 23 and the alternating current electric water pump 24 are fixedly connected with the end of the third water pipe 19 away from the filter tank 20. The output ends of the direct current electric water pump 23 and the alternating current electric water pump 24 are fixedly connected with the end of the first water pipe 17 away from the air pressure water storage tank 14. The two check valves 25 are respectively arranged on the output pipe lines of the direct current electric water pump 23 and the alternating current electric water pump 24. When the direct current electric water pump 23 or the alternating current electric water pump 24 stops running, the corresponding check valve is automatically closed to prevent the water in the air pressure water storage tank 14 from flowing back.

[0063] The power control component includes a water level controller 27 arranged in the water collecting tank 7. The water level controller 27 is connected with the external water source to monitor the water quantity in the water collecting tank 7. When the water quantity is lower than the normal value due to evaporation and other losses, the water level controller 27 automatically opens to supplement the water in the water collecting tank 7 from the external water source to ensure the normal operation of the equipment.

[0064] The power control component includes a direct current power supply 28, a self-provided alternating current generator 29, a power grid power supply 30 and a circuit manual-automatic controller 31. The direct current power supply 28, the self-provided alternating current generator 29 and the power grid power supply 30 are electrically connected with the circuit manual-automatic controller 31. The alternating current electric water pump 24 and the alternating current electric fan 26 are electrically connected with the self-provided alternating current generator 29 and the power grid power supply 30. The water level controller 27, the direct current electric water pump 23 and the direct current electric fan 9 are electrically connected with the direct current power supply 28. An alarm 32 is electrically connected with the circuit manual-automatic controller 31.

[0065] During the normal operation of the equipment, the direct current power supply 28 supplies power to the water level controller 27 and the circuit manual-automatic controller 31 in the water collecting tank 7. The power grid power supply 30 supplies power to the alternating current electric water pump 24 and the alternating current electric fan 26 to form a water curtain and an air current.

[0066] When the power supply 30 of the power grid is suddenly cut off, the circuit manual-automatic controller 31 automatically switches the power supply to the DC power supply 28, starts the DC electric fan 9 and the DC electric water pump 23, supplies water to the ventilation and spraying parts of the pedestrian passage 1, and sends an alarm through the alarm 32 to call the staff to start the self-provided AC generator 29. After the self-provided AC generator 29 is started and operates normally, the power supply is manually switched to the self-provided AC generator 29 power supply mode. After the power grid is restored to power supply, the power supply is manually switched to the power grid power supply 30 power supply mode, and the self-provided AC generator 29 is turned off.

[0067] The spraying part is also included, which can be used alone, and the solution sprayed by the spraying part is calcium hydroxide, which is used to kill and disinfect spores entering the cave.

[0068] Embodiment 3:

[0069] A tourism cave light-biological pollution treatment method using the method of claim 8:

[0070] S1: The spraying part is fixed on the top wall of the cave entrance, and the setting width of the spraying part depends on the size of the cave entrance. The water curtain formed by the spraying part must fill the cross section of the cavity at this place and have a certain thickness.

[0071] S2: The blowing part is arranged at the pedestrian passage 1, and the airflow direction is towards the outside of the cave and covers the entire aperture of the pedestrian passage 1.

[0072] S3: Multiple power supplies are used to ensure continuous and uninterrupted operation of the equipment.

[0073] S4: Spores that have entered the interior of the cave are killed and disinfected.

[0074] The plants growing in the tourism cave are mainly ferns and mosses.

[0075] Ferns mainly grow near the light source, the number is not large, and the growth is relatively large, which can be manually removed.

[0076] Moss plants are small in size and numerous in number, and cannot be manually removed, but can only be killed by chemicals.

[0077] The chemicals used to kill mosses must meet the following conditions: no damage to the landscape, no pollution to the environment, and relatively low price.

[0078] After screening, calcium hydroxide solution (limewater) is selected as the killing agent because it not only meets the above conditions, but also has a certain repairing effect on the damaged color of the landscape. The application of the moss killing agent is preferably by spraying. The agent is sprayed on the moss to be killed by a sprayer, so that the agent adheres to the moss. Because calcium hydroxide has strong alkalinity, the moss cannot withstand it and dies. Calcium hydroxide reacts with carbon dioxide in the air to form calcium carbonate, which is deposited on the surface of the landscape in the form of crystals, which can improve the color of the surface.

[0079] After starting the water curtain to wash the air into the cave, no more plant spores enter the cave. However, the spores that have entered the cave before are still suspended in the air in the cave and will gradually settle and attach to the landscape and germinate and grow. Through a period of settlement, the number of spores in the air in the cave will gradually decrease, so that eventually they disappear. Therefore, the moss on the landscape can be repeatedly killed several times, so that the spores that land on the landscape are killed after germination, and eventually all the spores in the air in the cave and on the landscape are completely removed.

[0080] At the same time as the repeated spraying to kill the moss, the calcium hydroxide sprayed eventually all turns into calcium carbonate crystals deposited on the landscape. Therefore, the repeated spraying to repair the color of the landscape is harmless and beneficial. The moss can be sprayed as many times as possible to ensure killing, but each time of spraying should be followed by several days before the next spraying.

[0081] Although the present scheme has fully considered that the water curtain can work continuously, it cannot completely rule out the possibility of accidental stoppage of work, for example, when it has to be stopped halfway due to a disaster.

[0082] If the device has to be stopped halfway due to a disaster, after the reason for stopping the water curtain is eliminated, the device is restarted to form a water curtain, and at the same time, the spraying and killing method is applied again to kill the spores that enter the cave during the period when the water curtain is stopped and the plants growing on the landscape.

[0083] It should be noted that the term "comprising" or any other variant is intended to cover non-exclusive inclusion, so that processes, methods, articles or devices including a series of elements not only include those elements, but also include other elements not explicitly listed, or include elements inherent to such processes, methods, articles or devices. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article or device including the element.

[0084] Although embodiments of the present application have been shown and described, it will be understood by those having ordinary skill in the art that various changes, modifications, alternatives and variations can be made thereto without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
