Description

Technical Field

[0001] This invention relates to the field of fire protection interface technology, specifically a fire protection interface based on intelligent adjustment for fire extinguishing. Background Technology

[0002] The interfaces on fire trucks are mainly divided into internal snap-on fire interfaces, clip-on fire interfaces, threaded fire interfaces, special-shaped interfaces, and suction pipe interfaces. Fire interfaces are mainly used to facilitate the connection between fire hoses, fire trucks, fire hydrants, and water guns. They are convenient and quick to use and can transfer water, foam, and mixed liquids.

[0003] Existing fire extinguishing interface connections typically use sealing rings for sealing. Under high pressure, the sealing effect is relatively poor, easily leading to water leakage. This, in turn, reduces water pressure, affecting fire rescue operations. Furthermore, existing fire extinguishing interfaces cannot intelligently adjust water pressure according to the water volume. When the water flow is too low, the spray height is insufficient; when the water flow is too high, excessive pressure is generated at the interface, which can reduce the service life of the interface over time. To solve the above problems, we propose a fire extinguishing interface based on intelligent adjustment for fire extinguishing. Summary of the Invention

[0004] To address the shortcomings of existing technologies and solve the aforementioned problems, this invention provides the following technical solution: a fire-fighting interface based on intelligent fire extinguishing adjustment, comprising a sealing assembly, wherein a hollow column is provided inside the sealing assembly, and pressure plates are provided on both sides of the hollow column. A push block is fixedly connected to the pressure plate via a crossbar, and a lower ball is supported by an arc-shaped structure at the top of the push block. A crossbar is fixedly connected to the top of the lower ball, and a support spring is fixedly connected to the top of the crossbar. An upper ball is fixedly connected to the top of the crossbar, and a compression block is slidably connected to the top of the upper ball.

[0005] It also includes an adjustment component, the interior of which is provided with a semi-circular pipe. A slide rod is fixedly connected to the outer wall of the semi-circular pipe. A connecting spring is fixedly connected to the side of the slide rod away from the semi-circular pipe. A groove block is fixedly connected to one end of the semi-circular pipe. A swing rod is slidably connected inside the groove of the groove block. A fixed rod is rotatably connected to the end of the swing rod away from the groove block.

[0006] It also includes an interface body, a sealing rubber ring on one side inside the interface body, a sealing component inside the interface body, a circular groove on the inner wall of the interface body, and an adjustment component inside the interface body.

[0007] Furthermore, the hollow columns are uniformly fixedly connected inside the interface body, effectively improving the sealing performance between the sealing rubber rings, and the upper and lower structures inside the interface body are symmetrically arranged.

[0008] Furthermore, the outer wall of the cross rod is slidably connected to the inner wall of the hollow column, and the side of the support spring away from the cross rod is fixedly connected to the inside of the hollow column, which facilitates the reset of the cross rod.

[0009] Furthermore, a sloping groove is provided on one side of the extrusion block, and the slope of this sloping groove is slidably connected to the top of the upper sphere. One side of the extrusion block is slidably connected to the inside of the interface body, and the other side abuts against the inner side of the sealing rubber ring, which facilitates the extrusion of one side of the sealing rubber ring.

[0010] Furthermore, semi-circular pipes are symmetrically arranged on the upper and lower sides inside the circular groove to facilitate control of water flow.

[0011] Furthermore, one end of the slide rod is slidably connected to the inside of the interface body, and the side of the connecting spring away from the slide rod is fixedly connected to the inside of the interface body.

[0012] Furthermore, the slot opening of the slot block is V-shaped, which facilitates the movement of the slot block.

[0013] Furthermore, the top of the swing arm has a conical structure, which facilitates the swing arm to drive the groove block to move.

[0014] Compared with the prior art, the present invention provides a fire protection interface based on intelligent fire suppression regulation, which has the following beneficial effects:

[0015] 1. This fire-fighting interface based on intelligent adjustment for fire extinguishing, when water flows through the interior of the interface body, the pressure plates on both sides of the hollow column drive the push block to move in the direction of the water flow, further causing the lower ball to drive the cross rod to move upward. At this time, the squeezing block will squeeze the inner side of the sealing rubber ring, making the sealing rubber ring between the two fire-fighting interfaces fit more tightly, thereby achieving the effect of avoiding water leakage from the fire-fighting interface due to poor sealing of the sealing ring under high pressure environment, which affects the fire-fighting rescue.

[0016] 2. This fire-fighting interface, based on intelligent adjustment for fire suppression, will cause the swing arm to deflect under the impact of the water flow when the water volume is large. This will cause the swing arm to move the groove block, at which point the upper and lower semi-circular pipes will separate from each other, increasing the internal channel space of the interface body and preventing excessive water pressure. When the water flow is small, the upper and lower semi-circular pipes will move inward under the action of the connecting spring, further reducing the internal channel space of the interface body and preventing excessively low water pressure. This achieves automatic and intelligent adjustment of water pressure, improving the practicality of the fire-fighting interface. Attached Figure Description

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] An example of the fire-fighting interface based on intelligent fire suppression regulation is as follows:

[0027] Please see Figures 1-7A fire-fighting interface based on intelligent fire extinguishing adjustment includes a sealing component 3. The sealing component 3 has hollow columns 31 inside, which are uniformly and fixedly connected to the interior of the interface body 1, effectively improving the sealing performance between the sealing rubber rings 2. The upper and lower structures inside the interface body 1 are symmetrically arranged. Pressure plates 32 are provided on both sides of the hollow columns 31. Push blocks 33 are fixedly connected to the pressure plates 32 via crossbars. The arc-shaped structure at the top of the push blocks 33 supports a lower ball 34. A cross rod 35 is fixedly connected to the top of the lower ball 34, and the outer wall of the cross rod 35 is slidably connected to the hollow column 31. The inner wall of the cross bar 35 is fixedly connected to the inside of the hollow column 31, and the side of the support spring 36 away from the cross bar 35 is fixedly connected to the inside of the hollow column 31 to facilitate the reset of the cross bar 35. The top of the cross bar 35 is fixedly connected to the support spring 36, and the top of the cross bar 35 is fixedly connected to the upper ball 37. The top of the upper ball 37 is slidably connected to the compression block 38. A groove is opened on one side of the compression block 38, and the slope of this groove is slidably connected to the top of the upper ball 37. One side of the compression block 38 is slidably connected to the inside of the interface body 1, and the other side abuts against the inside of the sealing rubber ring 2 to facilitate the compression of one side of the sealing rubber ring 2.

[0028] It also includes an adjustment component 5, which has a semi-circular pipe 51 inside. The upper and lower sides of the circular groove 4 are symmetrically provided with semi-circular pipes 51 to facilitate the control of water flow. A slide rod 52 is fixedly connected to the outer wall of the semi-circular pipe 51. A connecting spring 53 is fixedly connected to the side of the slide rod 52 away from the semi-circular pipe 51. One end of the slide rod 52 is slidably connected to the inside of the interface body 1, and the side of the connecting spring 53 away from the slide rod 52 is fixedly connected to the inside of the interface body 1. A groove block 54 is fixedly connected to one end of the semi-circular pipe 51. The groove opening of the groove block 54 is V-shaped to facilitate the movement of the groove block 54. A swing rod 55 is slidably connected inside the groove opening of the groove block 54. The top of the swing rod 55 is a conical structure to facilitate the swing rod 55 to drive the groove block 54 to move. A fixed rod 56 is rotatably connected to the end of the swing rod 55 away from the groove block 54.

[0029] It also includes an interface body 1, a sealing rubber ring 2 on one side inside the interface body 1, a sealing component 3 inside the interface body 1, a circular groove 4 on the inner wall of the interface body 1, and an adjustment component 5 inside the interface body 1.

[0030] Working principle: During use, when water flows through the interior of the interface body 1, the pressure plates 32 on both sides of the hollow column 31 are compressed. Since the pressure plates 32 are fixedly connected to the push block 33 via a crossbar, the push block 33 moves in the direction of the water flow. The lower ball 34 is supported by the arc-shaped structure at the top of the push block 33, and a crossbar 35 is fixedly connected to the top of the lower ball 34. Therefore, the lower ball 34 drives the crossbar 35 to move upwards. The upper ball 37 is fixedly connected to the top of the crossbar 35, and a compression device is slidably connected to the top of the upper ball 37. Block 38, therefore, will be subjected to the squeezing force of the upper ball 37 at this time. Since there is an inclined groove on one side of the squeezing block 38, and the slope of this inclined groove is slidably connected to the top of the upper ball 37, the squeezing block 38 will move at this time. Since one side of the squeezing block 38 is slidably connected to the inside of the interface body 1, and the other side abuts against the inside of the sealing rubber ring 2, the squeezing block 38 will squeeze the inside of the sealing rubber ring 2 at this time. At this time, the sealing rubber ring 2 between the two fire interfaces will fit more tightly, thereby achieving the effect of avoiding poor sealing of the sealing ring under high pressure, which would cause water leakage in the fire interface and affect fire rescue.

[0031] When the water supply is stopped, because the side of the support spring 36 away from the cross rod 35 is fixedly connected to the inside of the hollow column 31, the cross rod 35 will reset under the action of the support spring 36, which will further reset the squeezing block 38, thus preventing the squeezing block 38 from squeezing the sealing rubber ring 2 for a long time and affecting the service life of the sealing rubber ring 2.

[0032] When the water volume is large, because the end of the swing rod 55 away from the trough block 54 is rotatably connected to the fixed rod 56, the swing rod 55 will deflect under the impact of the water flow. Also, because the swing rod 55 is slidably connected inside the trough of the trough block 54, and the top of the swing rod 55 is a conical structure, the swing rod 55 can drive the trough block 54 to move. Furthermore, because one end of the semi-circular pipe 51 is fixedly connected to the trough block 54, and the outer wall of the semi-circular pipe 51 is fixedly connected to the sliding rod 52, with one end of the sliding rod 52 slidably connected inside the interface body 1, the upper and lower semi-circular pipes 51 will separate from each other, further increasing the channel space inside the interface body 1. This prevents the high-pressure water flow from generating too much pressure at the interface, thus affecting the service life of the interface.

[0033] When the water flow is low, because the side of the slide bar 52 away from the semi-circular pipe 51 is fixedly connected to the connecting spring 53, and the side of the connecting spring 53 away from the slide bar 52 is fixedly connected to the inside of the interface body 1, the upper and lower semi-circular pipes 51 will move inward under the action of the connecting spring 53, which further reduces the channel space inside the interface body 1. At this time, the water pressure is prevented from being too low, which would affect the water outlet height.

[0034] In summary, this fire-fighting interface based on intelligent fire extinguishing adjustment, when water flows through the interior of the interface body 1, the pressure plates 32 on both sides of the hollow column 31 drive the push block 33 to move in the direction of the water flow, further causing the lower ball 34 to drive the cross rod 35 to move upward. At this time, the squeezing block 38 will squeeze the inner side of the sealing rubber ring 2, making the sealing rubber ring 2 between the two fire-fighting interfaces fit more tightly, thereby achieving the effect of avoiding water leakage from the fire-fighting interface due to poor sealing of the sealing ring under high pressure environment, which affects fire rescue.

[0035] When the water flow is large, the swing arm 55 will deflect under the impact of the water flow, which will further cause the swing arm 55 to move the groove block 54. At this time, the upper and lower semi-circular pipes 51 will separate from each other, which will increase the channel space inside the interface body 1 and prevent the water pressure from being too high. When the water flow is small, the upper and lower semi-circular pipes 51 will move inward under the action of the connecting spring 53, which will further reduce the channel space inside the interface body 1 and prevent the water pressure from being too low. This achieves the effect of automatically and intelligently adjusting the water pressure and improving the practicality of the fire interface.
