Description

Technical Field

[0001] The utility model discloses a drooping sprinkler head splash plate with uniform water distribution, belonging to the technical field of fire fighting equipment. Background Art

[0002] A fire sprinkler is a type of sprinkler that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device based on a fire signal, and sprays water to extinguish fires according to the designed spraying shape and flow rate. A glass ball sprinkler is a common type of fire sprinkler. Its heat-sensitive element is a glass ball. When the sprinkler is heated, the working fluid in the glass ball takes effect, causing the ball to burst and open.

[0003] At present, the protection area of ​​existing sprinklers is several square meters, and fire may occur at any position within the protection area. This requires the water distribution of sprinkler nozzles to be as uniform as possible, without blind spots or insufficient water in some areas. Therefore, as the most critical component for evenly diverting and distributing water to achieve reliable fire extinguishing, the design of the splash plate is particularly important.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problem and to provide a drooping sprinkler head splash plate with uniform water distribution, which has the effect of uniform water distribution.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, including a splash plate, the splash plate includes a splash plate body and a plurality of splash plate teeth, the splash plate body is a circular structure, the plurality of splash plate teeth are evenly arranged along the circumference of the splash plate body, a through hole is opened in the center of the splash plate body, the upper end of the splash plate body is connected to a nozzle body, a yoke arm is arranged on the nozzle body, the plurality of splash plate teeth include a first tooth group, a second tooth group and a third tooth group, the first tooth group is arranged on the circumferential surface of the splash plate body and is parallel to the horizontal projection of the yoke arm, the second tooth group is arranged on the circumferential surface of the splash plate body and is at an angle of 45° with the horizontal projection of the yoke arm, the third tooth group is arranged on the circumferential surface of the splash plate body and is perpendicular to the horizontal projection of the yoke arm, the length of the teeth of the first tooth group is less than the teeth of the second tooth group, the length of the teeth of the third tooth group is greater than the teeth of the first tooth group and less than the teeth of the second tooth group.

[0007] By adopting the above technical scheme, the circular structure of the deflector plate body can change the columnar water flow sprayed from the nozzle main body into a surface shape, thereby increasing the coverage area of ​​the water flow, and the through hole opened in the center of the deflector plate body can be connected with bolts to fix the glass body on the nozzle main body, and the deflector plate teeth arranged on the outer peripheral surface of the deflector plate body can change the flow direction of the water flow, affecting the distribution and spraying range of the water flow. The longer the plate teeth are, the more water can be guided to the direction where the plate teeth are located. When the deflector plate teeth are parallel to the horizontal projection of the deflector plate body and the yoke arm, the water source splashes back severely, resulting in more water at the bottom and less water at a distance. Therefore, the teeth on the first disc tooth group are the shortest, which can effectively reduce the occurrence of backsplashing, and the second disc tooth group is located at a 45° angle between the splash plate body and the horizontal projection of the yoke arm frame. When the nozzle main body sprays water, the water flow is the smallest at this position. Therefore, the teeth of the second disc tooth group are the longest, which can guide more water to flow here, and then the third disc tooth group is located at a point where the splash plate body and the horizontal projection of the yoke arm frame are perpendicular. The water flow at this position is large, so the teeth of the third disc tooth group are of moderate length, longer than the teeth of the first disc tooth group and shorter than the teeth of the second disc tooth group, which can effectively prevent too much water from being splashed to this position.

[0008] Preferably, the deflector body and the plurality of deflector teeth are an integrated structure.

[0009] By adopting the above technical solution, the design of the integrated structure improves the stability and durability of the structure and reduces the problem of uneven water distribution caused by loose or damaged components.

[0010] Preferably, a plurality of the deflector plate teeth are provided with chamfers at one end away from the deflector plate body.

[0011] By adopting the above technical solution and setting the chamfers on the teeth of the splash plate, it is helpful to reduce the splashing of water, make the water flow more concentrated, and improve the water distribution efficiency.

[0012] Preferably, the number of teeth on the deflector plates is 12-16.

[0013] By adopting the above technical solution, the number of teeth on the deflector plate is within the range of 12-16, so that the deflector plate can guide the water flow stably.

[0014] Preferably, the width of the teeth of the deflector plate is 2.0-2.4 mm.

[0015] By adopting the above technical solution, the size of 2.0-2.4 mm helps to maintain the stability of the water flow while ensuring sufficient strength and rigidity.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] First, by arranging a number of splash plate teeth on the periphery of the splash plate body, and dividing the splash plate teeth into a first tooth group, a second tooth group and a third tooth group according to their distribution positions, the teeth of different tooth groups have different lengths, so that the flow rate and distance of the water flow are also different. The direction and intensity of the water flow are further adjusted by teeth of different lengths, so as to achieve a more uniform water distribution effect and improve its fire extinguishing efficiency;

[0018] Second, the deflector body and the teeth are an integrated structure, which not only simplifies the manufacturing process and reduces production costs, but also enhances the stability and durability of the structure and reduces the risk of failure caused by loose or damaged component connections;

[0019] Third, the chamfer design at the far end of each disc tooth can reduce the resistance of water flow, allowing the water to flow out of the disc teeth more smoothly, further improving the water distribution effect;

[0020] Fourthly, the number and width of the deflector teeth can be customized according to specific needs, which increases the applicability and flexibility of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] A pendant sprinkler splash plate with uniform water distribution, such as Figure 1-Figure 2 As shown, the water splash plate comprises a water splash plate body 1 and a plurality of water splash plate teeth 2. The water splash plate body 1 is a circular structure. The plurality of water splash plate teeth 2 are evenly arranged along the circumference of the water splash plate body 1. A through hole 3 is opened in the center of the water splash plate body 1. The upper end of the water splash plate body 1 is connected to a nozzle body. The water splash plate body 1 with a circular structure can change the columnar water flow sprayed by the nozzle body into a surface shape, thereby increasing the coverage area of ​​the water flow. The through hole 3 opened in the center of the water splash plate body 1 can be connected with bolts to fix the glass body on the nozzle body. The set water splash plate teeth 2 can change the flow direction of water, affect the distribution and spraying range of water flow, and a yoke arm frame 4 is set on the nozzle body. The plurality of water splash plate teeth 2 include a first tooth group 201, a second tooth group 202 and a third tooth group 203. The first tooth group 201 is set on the circumference of the water splash plate body 1 and is parallel to the horizontal projection of the yoke arm frame 4. The second tooth group 202 is set on the circumference of the water splash plate body 1 and is at an angle of 45° to the horizontal projection of the yoke arm frame 4. The third tooth group 203 is set on the circumference of the water splash plate body 1 and is parallel to the horizontal projection of the yoke arm frame 4. At the vertical projection, the disc teeth of the first disc tooth group 201 are shorter than the disc teeth of the second disc tooth group 202, and the disc teeth of the third disc tooth group 203 are longer than the disc teeth of the first disc tooth group 201 and shorter than the disc teeth of the second disc tooth group 202. The longer the disc teeth, the more water can be directed to the direction where the disc teeth are located. When the splash plate teeth 2 are in parallel with the horizontal projection of the splash plate body 1 and the yoke arm 4, the water source splashes back severely, resulting in more water below and less water far away. Therefore, the disc teeth on the first disc tooth group 201 are the shortest, which can effectively reduce the occurrence of splashing. The second disc tooth group 202 is located at a 45° angle between the horizontal projection of the splash plate body 1 and the yoke arm frame 4. When the nozzle body sprays water, the water flow is minimum at this position. Therefore, the disc teeth of the second disc tooth group 202 are the longest, which can guide more water to flow here. Then, the third disc tooth group 203 is located at a position where the horizontal projection of the splash plate body 1 and the yoke arm frame 4 is perpendicular. The water flow is large at this position. Therefore, the disc teeth of the third disc tooth group 203 are of moderate length, which are longer than the disc teeth of the first disc tooth group 201 and shorter than the disc teeth of the second disc tooth group 202, which can effectively prevent excessive water from being sprayed to this position.

[0026] The splash plate body 1 and a plurality of splash plate teeth 2 are an integrated structure. The design of the integrated structure improves the stability and durability of the structure and reduces the problem of uneven water distribution caused by loose or damaged parts. A plurality of splash plate teeth 2 are provided with chamfers at one end away from the splash plate body 1. The setting of the chamfers on the splash plate teeth 2 helps to reduce water splashing, makes the water flow more concentrated, and improves the water distribution efficiency.

[0027] The number of the splash plate teeth 2 is 12-16. Within this range, the splash plate can guide the water flow stably. The width of the splash plate teeth 2 is 2.0-2.4 mm. The width of the teeth is controlled between 2.0-2.4 mm. Such size selection helps to maintain the stability of the water flow while ensuring sufficient strength and rigidity.

[0028] The water splash plate of the utility model is provided with 16 water splash plate teeth 2 with a width of 2.2 mm on the periphery of the water splash plate body 1. At the same time, the water splash plate teeth 2 are grouped in pairs and divided into two groups of first tooth groups 201, four groups of second tooth groups 202 and two groups of third tooth groups 203 according to the distribution positions of the water splash plate teeth 2. The tooth lengths of different tooth groups are different, so that the flow rate and distance of the guided water flow are also different, so that the water splash plate can distribute water evenly, ensure that the water flow rate at each location under the spraying area covered by the water splash plate is consistent, and improve its fire extinguishing efficiency.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
