Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing devices, and in particular to a hidden water mist fire extinguishing device used for ancient buildings. Background Art

[0002] As people pay more and more attention to historical culture, various places have gradually begun to pay attention to the development and maintenance of ancient buildings. Ancient buildings refer to civil and public buildings with historical significance before the founding of the People's Republic of China, including buildings from the Republic of China period. In China, many ancient towns and most large cities still retain some ancient buildings. However, in the modern era of rapid construction, we must view and protect ancient buildings and the cultural characteristics they contain from a development perspective; we must preserve the ancient architectural culture and allow ancient cultural heritage to generate modern value.

[0003] At present, in order to better protect and facilitate people's appreciation of ancient buildings, ancient buildings are generally redeveloped, such as installing lighting devices, repairing ancient buildings again and deploying fire-fighting equipment. Among them, since many ancient buildings are wooden buildings, more attention is paid to the deployment of fire-fighting equipment.

[0004] Since it is difficult to deploy fire extinguishing devices in some ancient buildings, not only the actual fire extinguishing needs must be considered, but also it is not convenient to deploy atomizing fire extinguishing sprinklers and their water pipes inside the ancient buildings. Therefore, external fire extinguishing water cannons are mostly used. The external fire extinguishing water cannons are placed outdoors and then opened through the top plate to extinguish the fire. However, this type of fire extinguishing water cannon is generally replenished with water by manual timed intervals and does not have a rainwater collection mechanism. Therefore, the utilization of natural resources is not sufficient. At the same time, frequent replenishment of water sources is also troublesome. For this reason, we propose a hidden water mist fire extinguishing device for ancient buildings. Summary of the invention

[0005] The purpose of the present invention is to provide a hidden water mist fire extinguishing device for ancient buildings. By setting up a collection mechanism, it is convenient to filter and collect rainwater through the cooperation of a rainwater filtering component and a water collecting tank, and then replenish the rainwater into the water storage tank through a water inlet component, so as to make full use of natural resources and reduce the frequency of manual replenishment work.

[0006] To achieve the above object, the present invention provides the following technical solution: a hidden 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, a collecting mechanism is provided on the side of the water storage tank, and the collecting mechanism comprises: A water collecting tank, the water collecting tank is fixedly connected to one side of the water storage tank, and the water collecting tank is used to store rainwater; A rainwater filter assembly is placed on the top of the water collection tank, and the rainwater filter assembly is used to filter rainwater; A water inlet assembly, the water inlet assembly is fixedly connected to one side of the water collecting tank, and the water inlet assembly is used to connect the water collecting tank and the water storage tank; A support assembly is fixedly connected to both sides of the rainwater filtering assembly, a connecting assembly is provided between the support assembly and the water collecting tank, and the connecting assembly is used to connect the water collecting tank and the support assembly, and a liquid level sensor is fixedly installed on the inner wall surface of the water collecting tank.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides Figure 1-5The hidden water mist fire extinguishing device for ancient buildings shown in the figure comprises 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 collecting mechanism is arranged on the side of the water storage tank 1, and the collecting mechanism comprises: a water collecting tank 3, the water collecting tank 3 is fixedly connected to one side of the water storage tank 1, and the water collecting tank 3 is used to store rainwater; a rainwater filtering component 4, a rainwater filtering component 4 is placed on the top of the water collecting tank 3, and the rainwater filtering component 4 is used to filter rainwater; a water inlet component 5, the water inlet component 5 is fixedly connected to one side of the water collecting tank 3, and the water inlet component 5 is used to connect the water collecting tank 3 and the water storage tank 1; a supporting component 7, both sides of the rainwater filtering component 4 are fixedly connected with the supporting component 7, a connecting component 8 is arranged between the supporting component 7 and the water collecting tank 3, and the connecting component 8 is used to connect the water collecting tank 3 and the supporting component 7, and a liquid level sensor 9 is fixedly installed on the inner wall surface of the water collecting tank 3; when the ancient building site When it is raining or snowing, rainwater drops on the rainwater filter component 4, and is filtered by the rainwater filter component 4. The rainwater further falls into the water collecting tank 3. As the rainwater in the water collecting tank 3 continues to accumulate, when the rainwater liquid level reaches the liquid level sensor 9, the liquid level sensor 9 transmits a signal to the water inlet component 5. At this time, the water inlet component 5 starts to take in water, thereby filling the water storage tank 1 with water resources. In the later stage, the connecting component 8 can no longer be connected to the supporting component 7 and the water collecting tank 3, so that the rainwater filter component 4 can be removed, so as to clean the rainwater filter component 4, so that the rainwater filter component 4 can maintain a good filtering ability. When the water cannon fire extinguishing mechanism 2 starts 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, so that the water cannon fire extinguishing mechanism 2 is used to extinguish the fire. The water cannon fire extinguishing mechanism 2 is a prior art and will not be described in detail here.

[0025] It should be further explained that the rainwater filtering assembly 4 includes a fixed frame 401, a supporting 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 supporting basket 402, a fixed cover 404 placed on the top of the water collecting tank 3 and a first filter screen 405 fixedly connected to the outer surface of the fixed cover 404; when rainwater drops, it will be filtered through the first filter screen 405, then enter the supporting basket 402, and then be filtered through the second filter screen 403, and finally fall into the water collecting tank 3, thereby continuously accumulating inside the water collecting tank 3.

[0026] 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 the water inlet pipe 501 and extending to one end of the inside of the water collecting tank 3; a signal is transmitted to the electronic control valve 502 through the liquid level sensor 9, so that the electronic control valve 502 is opened, and the water is filtered by the water inlet filter assembly 503, and then enters the inside of the water storage tank 1 through the water inlet pipe 501. When the rainwater level inside the water collecting tank 3 is lower than the liquid level sensor 9, the liquid level sensor 9 transmits a signal to the electronic control valve 502, and the electronic control valve 502 is closed at this time, and the water inlet assembly 5 no longer takes in water.

[0027] Furthermore, the water inlet filter assembly 503 includes a connecting ring threadedly connected to the end of the water inlet pipe 501 and a circular filter fixedly connected to the inside of the connecting ring, and the liquid level sensor 9 is located above the water inlet assembly 5; rainwater is filtered by the circular filter, and the entire water inlet filter assembly 503 is horizontally arranged, which can effectively prevent impurities from accumulating on the circular filter and causing the circular filter to be blocked. The connecting ring can be rotated at a later stage to separate the water inlet filter assembly 503 from the water inlet pipe 501, thereby facilitating the replacement of the water inlet filter assembly 503.

[0028] Furthermore, a slag discharge assembly 6 is fixedly connected to the bottom of the water collecting tank 3, and the slag discharge assembly 6 includes a drainage pipe fixedly connected to the bottom end of the water collecting tank 3 and a drainage valve fixedly connected to the end of the drainage pipe; by opening the drainage valve, since a certain amount of rainwater is retained in the water collecting tank 3 itself, the rainwater will carry the impurities remaining in the water collecting tank 3 and be discharged along the drainage pipe, thereby eliminating the need for additional water flushing.

[0029] Furthermore, the support assembly 7 includes a support plate 701 fixedly connected to both sides of the fixed cover 404 and a bottom plate 702 fixedly connected to one end of the support plate 701, and the overall contour of the support plate 701 is L-shaped; when the fixed cover 404 is removed, the bottom plate 702 can be used to contact the ground for placement, thereby facilitating the cleaning of the first filter screen 405.

[0030] Furthermore, the bottom contour of the supporting basket 402 is set to be an arc shape, and two second filter screens 403 are symmetrically arranged on both sides of the arc-shaped bottom of the supporting basket 402; by setting the bottom of the supporting basket 402 to be an arc shape, impurities can be accumulated more concentratedly on the supporting basket 402, and at the same time, the second filter screen 403 is located on the side, which can avoid the impurities accumulated in the supporting basket 402 from directly clogging the second filter screen 403 to a certain extent.

[0031] Furthermore, the first filter 405 is a coarse filter, and the two second filter screens 403 are both fine filter screens, and the inner diameter of the filter holes of the fine filter screens is smaller than the inner diameter of the filter holes of the coarse filter screens; the first filter screen 405 is used to filter larger impurities to prevent large particles of impurities from entering the rainwater filter component 4, and the second filter screen 403 is used to filter smaller particles of impurities to prevent smaller particles of impurities from entering the water collection tank 3.

[0032] Furthermore, the connecting assembly 8 includes a fixed shell 801 fixedly connected to the middle of the water collecting tank 3, two moving rods 802 plugged into the fixed shell 801, a moving block 803 plugged between the two moving rods 802, a fixed sheet 805 fixedly connected to one end of the moving block 803, an inserting block 806 fixedly connected to both ends of the fixing sheet 805, a top block 808 fixedly connected to both sides of the middle of the moving block 803, a fixed round block 804 fixedly connected to one end of the moving block 803 extending to the outside of the fixed shell 801, a slot 807 opened on the outer surface of the moving rod 802 and a slot 808 fixedly connected to the end of the moving rod 802. The clamping assembly is fixedly connected; the clamping assembly includes a locking rod 809 fixedly connected to one end of the moving rod 802 and a locking groove 810 provided on the outer surface of the support assembly 7, and one end of the locking rod 809 is clamped with the inner part of the corresponding locking groove 810; when the rainwater filter assembly 4 needs to be removed, the fixed round block 804 is moved upward, so that the moving block 803 drives the fixing plate 805 to move upward synchronously, and at this time, the top block 808 will also move upward, and the top block 808 gradually stops pushing the moving rod 802, and then the insert block 806 is inserted into the slot 807, so that the two moving rods 802 are close to each other until the locking rod 80 9 is no longer engaged with the locking groove 810, and the fixed cover 404 can be moved up at this time, the fixed cover 404 and the first filter screen 405 can be removed, and then the fixed frame 401 can be moved up to take out the carrying basket 402, so as to facilitate the cleaning of the rainwater filter assembly 4, thereby maintaining the good filtering ability of the rainwater filter assembly 4. When installing, the fixed round block 804 is moved downward, thereby driving the moving block 803 to move downward, and then driving the fixing plate 805 to move downward, so that the plug 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. When gradually separating from the slot 807, the top block 808 will push the two moving rods 802 away from each other. When the plug block 806 starts to move, the top block 808 does not squeeze the moving rod 802, but waits until the plug block 806 moves a certain distance before the top block 808 starts to squeeze the moving rod 802. This can prevent the top block 808 from squeezing the moving rod 802 too early, causing the plug block 806 and the slot 807 to limit each other, thereby allowing the locking rod 809 to move outward until the locking rod 809 is engaged with the locking groove 810, thereby using the connecting component 8 to fix the support component 7, and then fix the rainwater filtering component 4.

[0033] Finally, it should be noted that the above 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 aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
