Description

Technical Field

[0001] This invention relates to the field of fire extinguishing device technology, and in particular to a concealed water mist fire extinguishing device for ancient buildings. Background Technology

[0002] As people increasingly value history and culture, various regions are gradually focusing on the development and maintenance of ancient buildings. Ancient buildings refer to pre-1949 civilian and public buildings of historical significance, including those from the Republican era. In China, many ancient towns and most major cities still retain some ancient buildings. However, in this era of rapid construction, we must view and protect ancient buildings and their inherent cultural characteristics with a developmental perspective; ensuring that ancient architectural culture is preserved for posterity while also generating modern value for ancient cultural heritage.

[0003] Currently, in order to better protect and facilitate people's appreciation of ancient buildings, they are generally redeveloped, such as installing lighting devices, repairing the ancient buildings, and deploying fire extinguishing equipment. Since many ancient buildings are wooden structures, the deployment of fire extinguishing equipment is given even more importance.

[0004] Because the deployment of fire extinguishing devices in some ancient buildings is quite difficult, it is necessary to consider not only the actual fire extinguishing needs, but also the inconvenience of deploying atomizing fire extinguishing nozzles and water pipes inside the ancient buildings. Therefore, external fire extinguishing water cannons are mostly used. These external fire extinguishing water cannons are placed outdoors and then opened through the top plate to extinguish the fire. However, these types of fire extinguishing water cannons are generally replenished manually at regular intervals and do not have rainwater collection mechanisms, so they do not make full use of natural resources. At the same time, frequent water replenishment is also quite troublesome. Therefore, we propose a concealed water mist fire extinguishing device for ancient buildings. Summary of the Invention

[0005] The purpose of this invention is to provide a concealed water mist fire extinguishing device for ancient buildings. By setting up a collection mechanism, rainwater can be filtered and collected through the cooperation of rainwater filtration components and a water collection tank. Then, the rainwater is replenished into the water storage tank through the water inlet component, thereby making full use of natural resources and reducing the frequency of manual replenishment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concealed water mist fire extinguishing device for ancient buildings, comprising a water storage tank and a water cannon fire extinguishing mechanism fixedly connected to the top of the water storage tank, wherein a collection mechanism is provided on the side of the water storage tank, and the collection mechanism includes:

[0007] A water collection tank is fixedly connected to one side of a water storage tank and is used to store rainwater.

[0008] A rainwater filtration assembly is placed on top of the water collection tank, and the rainwater filtration assembly is used to filter rainwater.

[0009] A water inlet assembly is fixedly connected to one side of the water collection tank and is used to connect the water collection tank and the water storage tank.

[0010] The rainwater filter assembly has support components fixedly connected to both sides. A connecting component is provided between the support component and the water collection tank, and the connecting component is used to connect the water collection tank and the support component. A liquid level sensor is fixedly installed on the inner wall of the water collection tank.

[0011] Preferably, the rainwater filtration assembly includes a fixed frame, a support basket fixedly connected to the bottom of the fixed frame, a second filter screen fixedly connected to both sides of the bottom of the support basket, a fixed cover placed on the top of the water collection tank, and a first filter screen fixedly connected to the outer surface of the fixed cover.

[0012] Preferably, the water inlet assembly includes a water inlet pipe fixedly connected to the outer surface of the water storage tank, an electronic control valve installed in the middle of the water inlet pipe, and a water inlet filter assembly threadedly connected to one end of the water inlet pipe extending into the inside of the water collection tank.

[0013] Preferably, a slag discharge assembly is fixedly connected to the bottom of the water collection tank. The slag discharge assembly includes a drainage pipe fixedly connected to the bottom of the water collection tank and a drainage valve fixedly connected to the end of the drainage pipe.

[0014] Preferably, the support assembly includes a support plate fixedly connected to both sides of the fixed cover and a base plate fixedly connected to one end of the support plate, and the overall outline of the support plate is L-shaped.

[0015] Preferably, the bottom contour of the carrying basket is set to be arc-shaped, and two second filter screens are symmetrically arranged on both sides of the arc-shaped bottom of the carrying basket.

[0016] Preferably, the first filter screen is a coarse filter screen, and both second filter screens are fine filter screens, wherein the inner diameter of the filter pores of the fine filter screen is smaller than that of the coarse filter screen.

[0017] Preferably, the connecting assembly includes a fixed shell fixedly connected to the middle of the water collection tank, two movable rods inserted into the inside of the fixed shell, a movable block inserted between the two movable rods, a fixed piece fixedly connected to one end of the movable block, insert blocks fixedly connected to both ends of the fixed piece, a top block fixedly connected to both sides of the middle of the movable block, a fixed round block fixedly connected to one end of the movable block extending to the outside of the fixed shell, a slot opened on the outer surface of the movable rod, and a snap-fit ​​assembly fixedly connected to the end of the movable rod.

[0018] Preferably, the locking assembly includes a locking rod fixedly connected to one end of the moving rod and a locking groove formed on the outer surface of the support assembly, and one end of the locking rod is locked into the interior of the corresponding locking groove.

[0019] Preferably, the water inlet filter assembly includes a connecting ring threaded to the end of the water inlet pipe and a circular filter screen fixedly connected to the inside of the connecting ring, and the liquid level sensor is located above the water inlet assembly.

[0020] The technical effects and advantages of this invention are as follows:

[0021] (1) Rainwater drips onto the rainwater filter assembly and is filtered by the rainwater filter assembly. The rainwater then falls into the water collection tank. As the rainwater accumulates in the water collection tank, when the rainwater level reaches the level sensor, the level sensor transmits a signal to the water inlet assembly. At this time, the water inlet assembly starts to fill the water storage tank with water resources. Meanwhile, the rainwater remaining in the water collection tank is convenient to carry the impurities in the water collection tank out later.

[0022] (2) By moving the fixed round block upward, the moving block drives the fixed plate to move upward synchronously. At this time, the top block will also move upward. The top block will gradually stop pushing the moving rod. Then the insert block is inserted into the slot, so that the two moving rods are close to each other until the locking rod is no longer engaged with the locking slot. At this time, the fixed cover can be moved upward, and the fixed cover and its first filter screen can be removed. Then the fixed frame can be moved upward, and the carrying basket can be removed. This makes it easier to clean the rainwater filter assembly, thereby maintaining the good filtration capacity of the rainwater filter assembly. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides, for example Figure 1-5The concealed water mist fire extinguishing device for ancient buildings shown includes a water storage tank 1 and a water cannon fire extinguishing mechanism 2 fixedly connected to the top of the water storage tank 1. A collection mechanism is provided on the side of the water storage tank 1, comprising: a water collection tank 3, fixedly connected to one side of the water storage tank 1, used to store rainwater; a rainwater filter assembly 4, placed on top of the water collection tank 3, used to filter rainwater; a water inlet assembly 5, fixedly connected to one side of the water collection tank 3, used to connect the water collection tank 3 and the water storage tank 1; and a support assembly 7, fixedly connected to both sides of the rainwater filter assembly 4. A connecting assembly 8 is provided between the support assembly 7 and the water collection tank 3, used to connect the water collection tank 3 and the support assembly 7. A liquid level sensor 9 is fixedly installed on the inner wall of the water collection tank 3. When the ancient building site... During rainy or snowy weather, rainwater drips onto the rainwater filter assembly 4 and is filtered by the rainwater filter assembly 4. The rainwater then falls further into the water collection tank 3. As the rainwater accumulates in the water collection tank 3, when the rainwater level reaches the level sensor 9, the level sensor 9 transmits a signal to the water inlet assembly 5. At this time, the water inlet assembly 5 begins to introduce water, thereby filling the water storage tank 1 with water resources. Later, the connecting assembly 8 can be disconnected from the support assembly 7 and the water collection tank 3, allowing the rainwater filter assembly 4 to be removed for cleaning, thus ensuring that the rainwater filter assembly 4 maintains good filtration capacity. When the water cannon fire extinguishing mechanism 2 begins to spray atomized water, the baffle above the water storage tank 1 will open, and the water storage tank 1 will supply water to the water cannon fire extinguishing mechanism 2, thereby using the water cannon fire extinguishing mechanism 2 for fire extinguishing. The water cannon fire extinguishing mechanism 2 is existing technology and will not be described in detail here.

[0031] It should be further explained that the rainwater filtration assembly 4 includes a fixed frame 401, a support basket 402 fixedly connected to the bottom of the fixed frame 401, a second filter screen 403 fixedly connected to both sides of the bottom of the support basket 402, a fixed cover 404 placed on the top of the water collection tank 3, and a first filter screen 405 fixedly connected to the outer surface of the fixed cover 404. When rainwater drips, it will be filtered by the first filter screen 405, then enter the support basket 402, and then be filtered by the second filter screen 403, and finally fall into the water collection tank 3, thus continuously accumulating inside the water collection tank 3.

[0032] Furthermore, the water inlet assembly 5 includes a water inlet pipe 501 fixedly connected to the outer surface of the water storage tank 1, an electronic control valve 502 installed in the middle of the water inlet pipe 501, and a water inlet filter assembly 503 threadedly connected to one end of the water inlet pipe 501 extending into the water collection tank 3. The level sensor 9 transmits a signal to the electronic control valve 502, thereby causing the electronic control valve 502 to open, so that the water inlet filter assembly 503 can filter the water, and then the water enters the water storage tank 1 through the water inlet pipe 501. When the rainwater level inside the water collection tank 3 is lower than the level sensor 9, the level sensor 9 transmits a signal to the electronic control valve 502, at which time the electronic control valve 502 closes, and the water inlet assembly 5 no longer inlets water.

[0033] Furthermore, the inlet filter assembly 503 includes a connecting ring threaded to the end of the inlet pipe 501 and a circular filter screen fixedly connected inside the connecting ring. The liquid level sensor 9 is located above the inlet assembly 5. Rainwater is filtered through the circular filter screen. At the same time, the entire inlet filter assembly 503 is horizontally arranged, which can effectively prevent impurities from accumulating on the circular filter screen and causing it to become clogged. Later, the connecting ring can be rotated to separate the inlet filter assembly 503 from the inlet pipe 501, thereby facilitating the replacement of the inlet filter assembly 503.

[0034] Furthermore, a slag discharge assembly 6 is fixedly connected to the bottom of the water collection tank 3. The slag discharge assembly 6 includes a drainage pipe fixedly connected to the bottom of the water collection tank 3 and a drainage valve fixedly connected to the end of the drainage pipe. By opening the drainage valve, since there is already some rainwater inside the water collection tank 3, the rainwater will carry the impurities left inside the water collection tank 3 and discharge them along the drainage pipe, so that no additional water flushing is required.

[0035] Furthermore, the support assembly 7 includes a support plate 701 fixedly connected to both sides of the fixed cover 404 and a base plate 702 fixedly connected to one end of the support plate 701, and the overall outline of the support plate 701 is L-shaped; when the fixed cover 404 is removed, the base plate 702 can be used to contact the ground for placement, thereby facilitating the cleaning of the first filter screen 405.

[0036] Furthermore, the bottom contour of the support basket 402 is set to be arc-shaped, and two second filter screens 403 are symmetrically arranged on both sides of the arc-shaped bottom of the support basket 402. By setting the bottom of the support basket 402 to be arc-shaped, it is convenient for impurities to accumulate more concentratedly on the support basket 402. At the same time, the second filter screens 403 are located on the side, which can to a certain extent prevent the impurities accumulated in the support basket 402 from directly clogging the second filter screens 403.

[0037] Furthermore, the first filter screen 405 is a coarse filter screen, and both second filter screens 403 are fine filter screens. The inner diameter of the filter holes of the fine filter screen is smaller than that of the coarse filter screen. The first filter screen 405 is used to filter larger impurities to prevent large particles from entering the rainwater filter assembly 4, while the second filter screens 403 are used to filter smaller particles to prevent them from entering the water collection tank 3.

[0038] Furthermore, the connecting assembly 8 includes a fixed housing 801 fixedly connected to the middle of the water collection tank 3, two movable rods 802 inserted into the interior of the fixed housing 801, a movable block 803 inserted between the two movable rods 802, a fixed piece 805 fixedly connected to one end of the movable block 803, insert blocks 806 fixedly connected to both ends of the fixed piece 805, a top block 808 fixedly connected to both sides of the middle of the movable block 803, a fixed circular block 804 fixedly connected to one end of the movable block 803 extending to the outside of the fixed housing 801, a slot 807 formed on the outer surface of the movable rod 802, and a slot at the end of the movable rod 802. A fixedly connected snap-fit ​​assembly includes a locking rod 809 fixedly connected to one end of the moving rod 802 and a locking groove 810 formed on the outer surface of the support assembly 7, with one end of the locking rod 809 snapping into the corresponding locking groove 810. When the rainwater filter assembly 4 needs to be removed, the fixed block 804 is moved upward, causing the moving block 803 to move the fixed piece 805 upward synchronously. At this time, the top block 808 also moves upward, and the top block 808 gradually stops pushing the moving rod 802. Then, the insert block 806 is inserted into the slot 807, causing the two moving rods 802 to move closer to each other until the locking rod 809 is engaged with the locking piece 802. 9. Once it is no longer engaged with the locking slot 810, the fixing cover 404 can be moved upwards, and the fixing cover 404 and its first filter screen 405 can be removed. Then, the fixing frame 401 can be moved upwards, and the carrying basket 402 can be removed to facilitate cleaning of the rainwater filter assembly 4, thereby maintaining the good filtration capacity of the rainwater filter assembly 4. During installation, the fixing block 804 is moved downwards, which in turn moves the moving block 803 downwards, which in turn moves the fixing piece 805 downwards, so that the insert block 806 gradually moves out of the slot 807. At the same time, when the moving rod 802 moves, it will drive the top block 808 to move synchronously. As the insert block 806 gradually moves out of the slot 807, the top block 808 will move synchronously. When the insert block 806 gradually separates from the slot 807, the top block 808 will push the two moving rods 802 away from each other. When the insert block 806 starts to move, the top block 808 does not squeeze the moving rods 802. Instead, it waits until the insert block 806 has moved a certain distance before the top block 808 starts to squeeze the moving rods 802. This avoids the top block 808 squeezing the moving rods 802 too early, which would cause the insert block 806 and the slot 807 to be mutually restricted. This causes the locking rod 809 to move outward until the locking rod 809 engages with the locking groove 810. This uses the connecting component 8 to fix the support component 7, thereby fixing the rainwater filter component 4.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
