Description

Technical Field

[0001] The invention relates to the field of fire-fighting equipment, in particular to a welding fire-fighting sprinkler. Background Art

[0002] Fire sprinklers are also called fire sprinkler heads. Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. They are divided into drooping sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc.

[0003] According to the definition in GB5135.1.3.1, a sprinkler is a water spraying device that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprays water according to the designed sprinkler shape and flow rate.

[0004] It mainly consists of a sprinkler, a liquid-filled thermosensitive glass bulb, a water pipe plug, and a water pipe. The thermosensitive glass bulb contains kerosene, ether, and other solutions. The operating temperatures of the various colors are: red 68°C, yellow 79°C, green 93°C, and blue 141°C. These are the most commonly used sprinkler heads, and red is the most commonly used in our daily lives.

[0005] The invention patent with Chinese patent application number 202010480351.2 discloses an anti-falling fire sprinkler, whose structure includes a connecting end, a frame, a sealing cover, a dispersion piece, and a supporting mechanism. The connecting end is welded to the frame, the sealing cover is connected to the frame, the dispersion piece is installed at the bottom of the frame, and the supporting mechanism is embedded in the frame. When the glass tube encounters a flame and bursts, the exploding fragments can be blocked by the contraction mechanism, so that the fragments generated by the burst of the contraction mechanism will not be ejected along with the water flow, and the thrust generated by the ejected water flow on the top block can cause the contraction mechanism to contract downward, thereby The water flow can be sprayed out smoothly to extinguish the flame. The elastic strip on the blocking ball can push the fitting surface outward, so that the fitting surface can always fit tightly with the inner wall of the outer frame, effectively preventing the fitting surface from being exposed to the air for a long time and causing oxidation wear, which causes external dust to enter the interior of the supporting mechanism through the gap between the fitting surface and the inner wall of the outer frame. The technical solution proposed in the above invention improves the structure of the fire sprinkler to make it have anti-falling properties, but the nozzle body is still a conventional drooping water spraying nozzle, which can only perform conventional umbrella-shaped spraying and is difficult to install on the side wall of the wall.

[0008] Furthermore, the plug is bowl-shaped, including a convex surface and a concave surface. The plug is covered with a sealing rubber layer. The convex surface of the plug seals the third through hole. A clamping groove is provided in the concave surface of the plug, and the glass support tube rests on the clamping groove.

[0009] Furthermore, the auxiliary support block is a plate-shaped structure, and the auxiliary support block extends along both sides of the width direction of the support frame to form a guide plate.

[0010] Furthermore, the dispersing portion includes a main dispersing plate and a secondary dispersing plate that are integrally formed, and a fourth through hole is provided at the center of the main dispersing plate.

[0011] Furthermore, a first guide dispersion piece and a second guide dispersion piece are provided on the four edges of the main dispersion plate, the first guide dispersion piece is triangular serrated, and the second guide dispersion piece is rectangular. The first guide dispersion piece and the second guide dispersion piece are relatively arranged on both sides of the main dispersion plate. Taking the support plate as a reference, the angle between the main dispersion plate and the support plate is 15-30°, the angle between the first guide dispersion piece and the support plate is 5-15°, and the second guide dispersion piece and the support plate are parallel to each other.

[0012] Furthermore, the auxiliary dispersion plate is arranged on one end of the main dispersion plate close to the second guide dispersion plate, and the auxiliary dispersion plate includes a first connecting plate, a second connecting plate and an auxiliary dispersion plate body. The first connecting plate and the main dispersion plate are in the same plane, and the angle between the second connecting plate and the main dispersion plate is 15-35°. The auxiliary dispersion plate body and the support plate are perpendicular to each other.

[0013] Furthermore, the auxiliary dispersing plate body includes a lower bottom surface close to the main dispersing plate and an upper top surface opposite thereto, and a plurality of guide grooves and a plurality of guide protrusions are provided on the lower bottom surface of the auxiliary dispersing plate body, and the guide grooves and the guide protrusions are arranged at intervals.

[0014] Furthermore, the guide protrusion is a hemispherical protrusion, and the vertical cross-section of the guide groove is arc-shaped.

[0015] Furthermore, the guide groove includes a first guide portion and a second guide portion, and the length of the second guide portion in the horizontal direction is half or one third of the first guide portion.

[0016] Furthermore, the thickness of the main dispersing plate is 2-3 mm, and the thickness of the secondary dispersing plate is 0.6-1.2 mm.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. Compared with the traditional fire sprinkler, the present invention is equipped with an auxiliary support block on the support frame. The function of the auxiliary support block is to provide auxiliary support for the support frame. When the fire sprinkler starts working, high-pressure water will pour out. On the one hand, the structure of the support frame cannot block or interfere with the water flow, and on the other hand, it must provide stable support. Therefore, the auxiliary support block can prevent the support frame from being compressed and deformed during operation, thereby affecting the work.

[0019] 2. The function of the plug in the present invention is to seal the water outlet, that is, the third through hole. By covering the entire body of the plug with a sealing rubber layer, better sealing can be provided when sealing the third through hole. The plug is configured as a bowl-shaped structure, which includes a convex surface and a concave surface. The structure of the convex surface is more consistent in the process of sealing the third through hole, while the concave surface can be more stable in cooperation with the glass support tube.

[0020] 3. The auxiliary support block is a plate-like structure, which is set on the support frame by welding. It extends on both sides of the width direction of the support frame to form a diversion plate. The function of the diversion plate is to properly divert the water flow when it pours out, so that most of the water flow can impact the dispersion part forward.

[0021] 4. The dispersion part includes an integrally formed main dispersion plate and a sub-dispersing plate. The main dispersion plate and the sub-dispersing plate are responsible for different spraying operations. A fourth through hole is provided at the center of the main dispersion plate. The purpose is that when the water flow hits the main dispersion plate and disperses to the surroundings, part of it will also be directly ejected through the fourth through hole, avoiding the hollowness of the spraying center and ensuring the uniformity of the spraying.

[0022] 5. The edges of the main dispersion plate are provided with a first guide dispersion piece and a second guide dispersion piece. During operation, the first guide dispersion piece and the second guide dispersion piece undertake different water flow guiding operations. The first guide dispersion piece is responsible for guiding the water flow downward and directly spraying it out, and the second guide dispersion piece is responsible for guiding the water flow upward to hit the auxiliary dispersion plate, thereby changing the direction of the water flow so that the water flow is divergent and sprayed forward and downward. The angle between the main dispersion piece and the support plate is 15-30 degrees. The setting of this angle can ensure that the spray The resistance of the outgoing water flow is reduced when it hits the main dispersion plate. At the same time, the main dispersion plate also has a drainage function. The lower half of the outgoing water column first hits the main dispersion plate under the action of gravity, and then sprays divergently downward along the first guide dispersion plate, while the upper half of the water column moves upward along the pouring main dispersion plate, and diverges vertically upward along the second guide dispersion plate to hit the secondary dispersion plate, and then its flow direction continues to change under the obstruction of the secondary divergent plate, and sprays divergently toward the front, so as to achieve a large-scale spraying fire extinguishing operation.

[0023] 6. The auxiliary dispersing plate body and the support plate are perpendicular to each other, and a plurality of guide grooves and a plurality of guide protrusions are provided on the lower bottom surface of the auxiliary dispersing plate body, wherein the auxiliary dispersing plate is perpendicular to the support plate, that is, parallel to the horizontal plane, and can guide the upward diverging water flow passing through the main dispersing plate to spray forward, and the purpose of setting the guide grooves and the guide protrusions is to be able to further disperse the water flow that is already in a divergent state, making it more divergent, and thus enabling it to have a larger spraying and coverage area. Therefore, the guide protrusion is set to a hemispherical protrusion to ensure that the process of dispersing the water flow is more gentle and moderate, and the vertical cross-section of the guide groove is arc-shaped, which includes a first drainage part and a second drainage part. The function of the first drainage part is to guide the water flow to enter the guide groove smoothly, and the function of the second drainage part is to guide the water flow guided into the guide groove downward quickly.

[0024] 7. The thickness of the main dispersing plate is 2-3mm, and the thickness of the auxiliary dispersing plate is 0.6-1.2mm. The material used is stainless steel plate or metal plate with stable properties. The auxiliary dispersing plate includes a first connecting plate, a second connecting plate and an auxiliary dispersing plate body. The metal plate itself has metal elastic properties. By setting the thickness of the auxiliary dispersing plate to 0.6-1.2mm, it is to make it cooperate with the impact force of the water flow and stimulate its own metal elastic force. When the water flow rushes out, part of the water flow will change its moving direction under the guidance of the main dispersing plate and turn to impact the auxiliary dispersing plate body on the auxiliary dispersing plate upward, and under the impact of the water flow, the auxiliary dispersing plate body will be affected by the impact of the water flow. The auxiliary dispersion plate body will shake up and down under the action of its own metal elastic properties, and cooperate with the guide grooves and guide protrusions on the lower surface of the auxiliary dispersion plate body to simulate the slapping action of the impact water flow during the up and down shaking process, so as to continuously slap the divergent water flow, so that it can be sprayed obliquely forward in a more divergent form. At the same time, with continuous shaking and slapping, the water flow can also be sprayed to the ground at a faster speed, because the auxiliary dispersion plate body provides a downward force for the water flow during the slapping process, and in the continuous shaking process, the coverage area of ​​the divergent water flow is increased and the spraying can be evenly distributed within the covered area, thereby improving the efficiency of fire extinguishing.
