Description

Technical Field

[0001] The utility model relates to an anti-clogging fire sprinkler, in particular to an anti-clogging fire sprinkler used in the field of fire fighting technology. Background Art

[0002] A fire sprinkler is a type of sprinkler that automatically activates within a predetermined temperature range under the action of heat, or is activated by a control device based on a fire signal, and sprays water to extinguish the fire according to the designed spraying shape and flow rate. A glass ball sprinkler is a common type of fire sprinkler. Its thermal element is a glass ball. Normally, the glass ball is pressed against a copper sheet, which blocks the water outlet. During a fire, the glass ball is heated, and the working fluid inside the glass ball takes effect, causing the ball to explode and the copper sheet to detach. Pressurized water begins to spray to extinguish the fire and reduce the temperature. The spraying direction is controlled by a water baffle.

[0003] The specification of Chinese patent CN214209245U discloses a fire sprinkler head, comprising a connecting head, a copper sheet is provided at the lower end of the connecting head, and connecting rods are fixedly connected to the lower ends of the connecting rods at both sides of the lower end of the connecting head, and a fixing seat is fixedly provided at the lower end of the connecting rod, and a glass ball is provided between the fixing seat and the copper sheet, and a water baffle is provided at the lower end of the fixing seat, and a rotating rod is fixedly connected to the water baffle. By placing the lower end of the glass ball in the groove of the abutment, the copper sheet is contacted with the connecting head, and then the glass ball is pressed down to clamp the upper end of the glass ball into the groove of the copper sheet, the glass ball is fixed under the action of a compression spring, and then the rotating block is driven to rise by rotating the water baffle to squeeze and fix the glass ball. By arranging a compression spring between the rotating block and the abutment, the glass ball cannot continue to rotate when it is subjected to sufficient pressure, so that the glass ball is subjected to a reasonable pressure, which neither is squeezed nor broken, and the copper sheet is prevented from being subjected to too little force to cause water leakage, and the installation is simple.

[0004] Existing fire sprinklers are prone to clogging during use due to impurities, scale, etc. in the water, thereby affecting the water spraying effect and fire extinguishing efficiency. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing fire sprinkler heads are easily clogged due to impurities, scale, etc. in the water during use, thereby affecting the water spraying effect and fire extinguishing efficiency.

[0006] In order to solve the above problems, the utility model provides an anti-clogging fire sprinkler, comprising a fire sprinkler body, the bottom of the fire sprinkler body is fixedly connected to the base, the top of the fire sprinkler body is fixedly connected to the interface, the top of the base is drilled with a first groove, the first groove is fixedly connected to the electric push rod, the top of the electric push rod is installed with a first support column, the bottom end of the first support column is drilled with a second groove, and the power end of the electric push rod is fixedly connected to the top wall of the second groove, and the length of the movable rod of the second groove is the same as the height of the first groove, the top of the first support column is installed with a glass tube, and the glass tube is filled with temperature sensing liquid, the interface is movably connected with a water inlet, and the bottom end of the water inlet is in conflict with the glass tube, and two groups of water outlets are symmetrically opened on the side walls of the water inlet, and the bottom end of the interface is symmetrically fixed with an extension plate, and the inner wall of the extension plate is drilled with a slide groove extending to the inner wall of the interface, and the water inlet is slidably connected to the slide groove through a slider, and the top of the water inlet is detachably connected with a filter.

[0007] In the above-mentioned fire sprinkler, through the above, it is effectively achieved that when a fire occurs indoors, the water flow is filtered through the filter before being sprayed out to avoid clogging of the water outlet on the water inlet, and at the same time, the water output can be automatically controlled according to the fire situation.

[0008] As a further improvement of the present application, an upper limit block is provided on the bottom of the interface, a lower limit block is provided on the top of the base, and a leakage net is detachably connected to the lower limit block and the upper limit block.

[0009] As a further improvement of the present application, elastic ropes are fixedly connected to both ends of the leakage net, and the elastic ropes are respectively engaged with the lower limit block and the upper limit block.

[0010] As a further improvement of the present application, a tightening belt is installed on the side wall above the elastic rope at the bottom of the net, a drawstring is inserted into the tightening belt, and a spring buckle is connected to the surface of the drawstring.

[0011] As another improvement of the present application, a threaded groove is provided at the top of the water inlet, a threaded ring corresponding to the threaded groove is fixedly connected to the bottom end of the filter screen, and the threaded ring is threadedly connected to the threaded groove.

[0012] As another improved supplement of the present application, the electric push rod is electrically connected to a remote control, and a smoke sensor is fixedly connected to the interface.

[0013] In summary, when installing the fire sprinkler body indoors, first put the bottom of the leakage net on the lower limit block through the elastic rope, then pull the drawstring and shrink the tightening belt through the spring buckle, so as to tighten the bottom of the leakage net above the lower limit block, and then clamp the upper elastic rope on the upper limit block to constrain the leakage net. At this time, when the installed fire sprinkler body encounters a fire, the first support column of the glass ball will fall into the leakage net after breaking, and it will be collected. At the same time, when the filter is located outside the interface and loses its filtering effect, large impurities in the water can be filtered. The leakage net is made of steel wire and is designed with a fine mesh. The shattered debris can be caught while preventing it from being cut by the broken glass ball first support column. After the fire is extinguished, the top of the filter net can be removed from the upper limit block and the outlet above the filter net can be held. The bottom of the filter net can then be removed from the lower limit block. Since the tightening belt on the lower limit block is in a tightened state, the objects inside will not fall when separated from the lower limit block. The broken glass ball first support column can be effectively handled by installing the filter net to avoid it from falling on the ground and posing a safety hazard. At the same time, it can filter out large impurities in the water when the filter loses its filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-5 The invention discloses an anti-clogging fire sprinkler, comprising a fire sprinkler body 1, wherein the bottom of the fire sprinkler body 1 is fixedly connected to a base 3, the top of the fire sprinkler body 1 is fixedly connected to an interface 2, a first groove 9 is cut at the top of the base 3, an electric push rod 13 is fixedly connected in the first groove 9, a first support column 4 is installed at the top of the electric push rod 13, a second groove 14 is cut at the bottom end of the first support column 4, and the power end of the electric push rod 13 is fixedly connected to the top wall of the second groove 14, and the length of the movable rod of the second groove 14 is the same as the height of the first groove 9, a glass tube 7 is installed at the top of the first support column 4, and the glass tube 7 is filled with a temperature-sensitive liquid, a water inlet 11 is movably connected in the interface 2, and the bottom end of the water inlet 11 conflicts with the glass tube 7, a pressure sensor is installed on the top end face of the first support column 4, and after the glass tube 7 is broken, the water inlet 11 falls and contacts the pressure sensor;

[0026] Two sets of water outlets 12 are symmetrically opened on the side wall of the water inlet 11. The bottom end of the interface 2 is symmetrically fixedly connected to an extension plate 20. The inner wall of the extension plate 20 is carved with a chute 21 extending to the inner wall of the interface 2. The water inlet 11 is slidably connected to the chute 21 through a slider 22. The top of the water inlet 11 is detachably connected to the filter 10;

[0027] The electric push rod 13 is electrically connected to the remote control, a smoke sensor is fixedly connected to the interface 2, a threaded groove 8 is provided at the top of the water inlet 11, and a threaded ring 15 corresponding to the threaded groove 8 is fixedly connected to the bottom of the filter 10, and the threaded ring 15 is threadedly connected to the threaded groove 8.

[0028] Working principle: When a fire occurs indoors, the room temperature rises to a certain height, and the temperature-sensing liquid in the glass tube 7 expands and breaks due to the heat. At this time, the water inlet 11 in the interface 2 loses its support and automatically slides down through the slider 22 to collide with the first support column 4. At this time, a group of water outlets 12 located below the water inlet 11 are exposed outside the interface 2. When the glass tube 7 breaks, the water valve in the interface 2 automatically opens to fill the water inlet 11. Before entering the water inlet 11, the water is filtered through the filter 10. Then the water enters the water inlet 11 and is discharged from the exposed water outlet 12 to extinguish the fire. When the fire gradually grows, smoke will be generated. At this time, the smoke sensor detects it and transmits the signal to the controller to automatically start the electric push rod 13, and the electric push rod 13 moves downward Move halfway, and at this time both sets of water outlets 12 are exposed outside the base 3. Increasing the water output can speed up the fire extinguishing efficiency. When the mesh of the filter screen 10 is clogged during long-term filtration, the pressure on the filter screen 10 increases during the water spraying process, and further pressurizes the pressure sensor at the top of the first support column 4. When the pressure value detected by the pressure sensor at the top of the first support column 4 is greater than the set threshold, a control signal is sent to the electric push rod; the electric push rod 13 is fully retracted, so that the second groove 14 is fully inserted into the first groove 9. At this time, the water inlet 11 and the filter screen 10 slide to the bottom of the slide 21 through the slider 22, so that the filter screen 10 slides out of the interface 2 and there is a gap between the interface 2. At this time, water avoids the filter screen 10 and the water inlet 11 and flows out directly from the interface 2 to avoid blockage.

[0029] Through the above, it is effectively achieved that when a fire occurs indoors, the water flow is filtered through the filter 10 before being sprayed out to avoid clogging of the water outlet 12 on the water inlet 11, and at the same time, the water output can be automatically controlled according to the fire situation.

[0030] Second implementation method:

[0031] The figure shows 1 and Figure 6-7 An upper limit block 6 is provided at the bottom of the interface 2, and a lower limit block 5 is provided at the top of the base 3, and a leakage net 16 is detachably connected to the lower limit block 5 and the upper limit block 6. Elastic ropes 17 are fixedly connected to both ends of the leakage net 16, and the elastic ropes 17 are respectively engaged with the lower limit block 5 and the upper limit block 6. A tightening belt 19 is installed on the side wall above the elastic rope 17 at the bottom of the leakage net 16, and a drawstring 18 is inserted in the tightening belt 19, and a spring buckle is connected to the surface of the drawstring 18.

[0032] Working principle: When installing the fire sprinkler body 1 indoors, first put the bottom of the leakage net 16 on the lower limit block 5 through the elastic rope 17, then pull the drawstring 18 and shrink the tightening belt 19 through the spring buckle, so as to tighten the bottom of the leakage net 16 above the lower limit block 5, and then clamp the upper elastic rope 17 on the upper limit block 6 to constrain the leakage net 16. At this time, when the installed fire sprinkler body 1 encounters a fire, the glass ball first support column 4 will fall into the leakage net 16 after breaking, and at the same time, the filter 10 will be When the filtering effect is lost outside the interface 2, large impurities in the water can be filtered, and the filter 16 is made of steel wire and is designed with a fine mesh, which can catch the debris while preventing it from being cut by the broken glass balls. The first support column 4 can be used to prevent the filter from being cut by the broken glass balls. After the fire is extinguished, the top of the filter 16 can be removed from the upper limit block 6 and the outlet above the filter 16 can be held. The bottom of the filter 16 can then be removed from the lower limit block 5. Since the tightening belt 19 on the lower limit block 5 is in a tightened state, the objects inside will not fall out when it is separated from the lower limit block 5.

[0033] Through the above, the broken glass balls of the first support column 4 can be effectively processed by installing the leakage net 16 to avoid falling on the ground and posing a safety hazard. At the same time, large impurities in the water can be filtered out when the filter net 10 loses its filtering effect.

[0034] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
