Chemical power supply connection device with fire protection

Abstract

This invention relates to the field of chemical power source technology, and in particular to a chemical power source connection device with fire-fighting function. The device integrates fire-fighting function with the chemical power source connection device. Through the coordinated linkage of a temperature-sensing trigger mechanism, a push-out mechanism, and a fire-fighting activation mechanism, when a fire occurs in the casing and the temperature reaches a threshold, the push-out mechanism first forcibly pushes out the external plug in the external socket, disconnecting the external discharge circuit and preventing the electrical appliance from continuously discharging to the chemical power source. Simultaneously, the plug is pushed out, and the socket is sealed and isolated, providing a sealed environment for the subsequent spraying of fire-fighting media. Subsequently, the fire-fighting activation mechanism delays the opening of the angle valve, spraying fire-fighting media into the casing through the nozzle, achieving an orderly connection between power outage and fire extinguishing. During the process of the lever rotating to trigger the angle valve and drive the push rod to open, the force-applying length of the lever automatically extends and acts on the push rod, compensating for the problem of insufficient lever rotation angle due to space constraints, increasing the opening channel for the fire-fighting media, and facilitating rapid fire extinguishing.

Description

Technical Field

[0001] This invention relates to the field of chemical power source technology, and in particular to a chemical power source connection device with fire-fighting function. Background Technology

[0002] Chemical power sources directly convert chemical energy into electrical energy through internal redox reactions. Their basic structure includes positive and negative electrodes where the reaction occurs, an electrolyte for ion conduction, and a membrane. Key performance indicators include voltage, capacity, and energy density. Main types include non-rechargeable primary batteries (such as alkaline batteries), recyclable secondary batteries (such as batteries using lithium-ion, sodium-ion, or other material systems), and fuel cells that rely on external fuel for continuous power generation (such as hydrogen fuel cells).

[0003] Existing power connection devices cannot promptly cut off the external discharge circuit when a fire occurs at a chemical power source, leading to continuous discharge and Joule heating that exacerbates thermal runaway. At the same time, the open socket is not conducive to the formation of a fire-fighting environment. When opening fire valves, space constraints make it difficult to achieve a large opening angle, prolonging the spraying time of the fire-fighting medium and increasing the difficulty of controlling the fire.

[0004] Chinese patent document (publication number: CN211655778U) discloses a fireproof device for emergency energy storage power supply. It achieves buffering and shock absorption by setting a combination structure of shock-absorbing springs, hardwood layers, and alkaline resin layers inside the box; it uses a cooling fan and multiple ventilation holes in conjunction with desiccant and filters to improve ventilation, heat dissipation, moisture and dust prevention capabilities; it adopts a dual terminal block design so that the energy storage power supply can power the monitoring system and slowly discharge; however, the existing documents do not provide a preferred solution to solve the technical problem of this application.

[0015] Furthermore, when an external plug is connected to the external socket, the protective pin of the external plug extends into the protective socket, and the power pin of the external plug extends into the power socket, and respectively contacts the corresponding contact spring.

[0016] The device described in this invention has the following beneficial effects: 1. This invention integrates fire-fighting functions with a chemical power supply connection device. Through the coordinated linkage of a temperature-sensing trigger mechanism, an ejection mechanism, and a fire-fighting activation mechanism, when the shell experiences a fire and the temperature reaches a threshold, the ejection mechanism first forcibly pushes out the external plug in the external socket; disconnecting the external discharge circuit, preventing electrical appliances from continuously discharging to the chemical power supply, and eliminating the continuous driving force of the external discharge circuit on the thermal runaway of the chemical power supply. This solves the problem that traditional power connection devices cannot actively disconnect and cut off the external discharge circuit when a fire occurs, and that continuous power supply from electrical appliances exacerbates the spread of thermal runaway. More importantly, while pushing out the plug, the socket is also sealed and isolated, providing a sealed environment for the subsequently sprayed fire-fighting medium, isolating oxygen from entering, and shortening the time to extinguish the fire. Subsequently, the fire-fighting activation mechanism opens the angle valve with a delay, and the fire-fighting medium is sprayed into the housing through the nozzle, realizing an orderly connection between power outage and fire extinguishing. It coordinates the use safety of chemical power sources at both the electrical safety and fire response levels. More importantly, when the lever rotates to trigger the angle valve and drive the push rod to open, the force applied by the lever automatically extends and acts on the push rod, compensating for the problem of insufficient lever rotation angle caused by space constraints. This timely increases the rotation angle of the push rod, increases the opening channel of the fire-fighting medium, and facilitates the rapid extinguishing of the fire.

[0017] 2. In the device of the present invention, when a fire is triggered, the temperature-sensing triggering mechanism drives the first hook plate to rotate and release the first hanging ring. The tension spring drives the sliding plate and the push foot to pop out quickly, forcibly pushing the power plug and the protection plug out of the power socket and the protection socket. The truncated pyramid-shaped seal at the base of the push foot then seals each socket, providing a sealed environment for the subsequently sprayed fire-fighting medium, isolating oxygen from entering, and shortening the time to extinguish the fire. In addition, under normal conditions, the slit-shaped slide causes the compression spring and the power contact spring to form a double spring clamp on the power plug, and the protection spring clamps the protection plug, ensuring reliable contact between the plug and the spring under normal use. When a fire is triggered, the slit-shaped slide first moves the compression spring away from the power plug, releasing the clamping constraint on the plug, allowing the push foot to smoothly push out each plug, reducing resistance during the pushing process, improving the responsiveness of the pushing action, and solving the problem of interference of the spring clamping force on the emergency pushing action in the traditional structure.

[0018] 3. In the device of this invention, the fire-fighting opening mechanism is designed as a linkage structure in which the guide frame drives the lever assembly to actuate the angle valve push rod using the lever principle. When the fire is triggered, the third tension spring drives the guide frame to slide along the guide rod, and the lever rotates around the pin as the fulcrum, applying a pulling force to the angle valve push rod. During the rotation of the lever around the pin, the arc trajectory of the crossbar rotation is limited by the top of the double-mouth frame, generating a reverse thrust, causing the extension rod to slide outward along the inner cavity of the lever. The one-way locking structure of the ratchet and ratchet teeth locks the extension rod after it extends a certain amount, preventing it from retracting due to elastic rebound. As the crossbar extends with the extension rod, the contact range between it and the push rod continues to increase, further expanding the opening angle of the angle valve. This ratchet extension design helps to maintain a large actuation stroke even when the contact area of ​​the angle valve push rod decreases, reducing the negative impact of poor angle valve opening on the flow of fire-fighting media, thereby improving the reliability of fire-fighting media release.

[0019] 4. This invention does not employ an electronic control structure, relying entirely on the sequential linkage of a purely mechanical structure to complete the two core actions of power outage and fire extinguishing. This design eliminates the need for the device to rely on power supply, signal transmission, or normal operation of the control program during a fire, fundamentally avoiding the risk of fire response interruption caused by the potential failure of electronic controls in fire-related environments such as high temperature, overload, or damaged wiring. Even under extreme conditions where the chemical power source itself has undergone thermal runaway, the device can still maintain stable and reliable triggering capability, which helps to improve the actual effectiveness of fire protection under harsh conditions.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] Example 1:

[0025] like Figure 1-10 As shown, a chemical power supply connection device with fire-fighting function includes a housing 11 with an external connector 12, a power supply body 15 inside the housing 11, a storage cavity 16 between the side wall of the housing 11 and the power supply body 15, and a fire-fighting medium sealed and stored in the storage cavity 16; a nozzle 17 is provided at the top inside the housing 11, and the nozzle 17 is connected to the storage cavity 16 through a conduit, with an angle valve connected in series on the conduit; an ejection mechanism 22 is provided inside the housing 11 corresponding to the external connector 12, and a rotating rod 1 is provided on one side of the ejection mechanism. 8. A temperature-sensing trigger mechanism is provided at the end of the rotating rod 18; at least two hook plates are fixed at intervals on the rotating rod 18, the first hook plate 20 is hooked to the ejection mechanism 22; the second hook plate 21 is hooked to the fire-fighting opening mechanism 23, and the push rod 24 of the angle valve abuts against the fire-fighting opening mechanism 23; wherein, heat dissipation fins 13 are provided on the housing 11; the fire-fighting medium inside the storage chamber 16 can be carbon dioxide; the two ends of the angle valve are connected by a fire-fighting medium pipeline 64, one end is connected to the storage chamber 16, and the other end is connected to the nozzle 17; a display screen 14 is also provided on the outside of the housing 11.

[0026] This invention integrates fire-fighting functions with a chemical power supply connection device. Through the coordinated action of a temperature-sensing trigger mechanism, an ejection mechanism 22, and a fire-fighting activation mechanism 23, when the shell experiences a fire and the temperature reaches a threshold, the ejection mechanism 22 first forcibly pushes out the external plug in the external socket 12. This disconnects the external discharge circuit, preventing electrical appliances from continuously discharging to the chemical power supply and eliminating the continuous driving force of the external discharge circuit on the thermal runaway of the chemical power supply. This solves the problem that traditional power connection devices cannot actively disconnect and cut off the external discharge circuit during a fire, and that continuous power supply from electrical appliances exacerbates the spread of thermal runaway. More importantly, while pushing out the plug, the socket is also sealed and isolated, providing a sealed environment for the subsequently sprayed fire-fighting medium, isolating oxygen from entering, and shortening the time to extinguish the fire. Subsequently, the fire-fighting activation mechanism 23 opens the angle valve with a delay, and the fire-fighting medium is sprayed into the housing 11 through the nozzle 17, realizing the orderly connection between power failure and fire extinguishing. It coordinates the use safety of chemical power source at both the electrical safety and fire response levels. More importantly, when the lever 60 rotates to trigger the angle valve and drives the push rod 24 to open, the force application length of the lever 60 automatically extends and acts on the push rod 24, which makes up for the problem of insufficient rotation angle of the lever due to space constraints. It promptly increases the rotation angle of the push rod 24, increases the opening channel of the fire-fighting medium, and facilitates the rapid extinguishing of the fire.

[0027] Furthermore, the temperature-sensing triggering mechanism includes a support plate 26 fixed to the top of the housing 11. The support plate 26 has an opening, and a cylinder 27 is fixed to the inner wall of the opening. A piston is slidably sleeved inside the cylinder 27, and a thermal expansion medium is sealed inside the cylinder 27. The connecting rod 28 of the piston slides through the side wall of the opening and extends to the outside. A toothed plate 29 is fixed to the free end of the connecting rod 28. The toothed plate 29 meshes with a gear 19, and the gear 19 is fixedly sleeved on a rotating rod 18. The two ends of the rotating rod 18 are mounted on the housing through bearings.

[0028] When a fire occurs inside the housing 11 and the temperature rises, the thermal expansion medium inside the cylinder 27 increases in volume due to the heat, pushing the piston inside the cylinder 27 to move axially along the cylinder 27. The piston transmits the linear displacement to the gear plate 29 through the connecting rod 28. The gear plate 29 meshes with the gear 19, converting the linear motion of the connecting rod 28 into the rotational motion of the gear 19, which in turn drives the rotating rod 18, which is fixedly sleeved on the gear 19, to rotate synchronously, providing driving force for the subsequent linkage triggering of the first hook plate 20 and the second hook plate 21.

[0029] The support plate 26 is fixed inside the top of the housing 11 and provides stable support for the cylinder 27. The structural design of the connecting rod 28 sliding through the side wall of the opening guides and constrains the movement direction of the connecting rod 28, which helps to ensure the stability and reliability of the transmission between the toothed plate 29 and the gear 19, so that the temperature sensing signal can be smoothly converted into the mechanical rotation output of the rotating rod 18, which is the basis of the entire fire linkage response.

[0030] The thermal expansion medium inside cylinder 27 can be high melting point paraffin or microcrystalline wax.

[0031] Furthermore, the first hook plate 20 has a first inner ring groove 25 in the shape of a quarter arc segment, and a through opening is provided in the first inner ring groove 25 in the radial direction to connect with the outside; the second hook plate 21 has a second inner ring groove in the shape of a third arc segment, and a through opening is provided in the second inner ring groove in the radial direction to connect with the outside.

[0032] Under normal conditions, the hook rings of the ejection mechanism 22 and the fire-fighting opening mechanism 23 are respectively engaged in the inner ring grooves of the corresponding hook plates and remain locked due to the constraint of the arc segment.

[0033] When the temperature-sensitive triggering mechanism drives the rotating rod 18 to rotate, the first hook plate 20 only needs to rotate through a quarter arc to make the through-hole turn to the hanging ring position. The hanging ring comes out through the through-hole, and the ejection mechanism 22 is triggered first, quickly pushing out the pin inserted into the external socket 12 and forming a blockage. The second inner ring groove of the second hook plate 21 is three-quarters long. The rotating rod 18 must be rotated to a larger angle before the through opening can be rotated to the corresponding hanging ring position, and the fire opening mechanism 23 can be unlocked and triggered.

[0034] The design of this arc segment with varying lengths creates a clear time lag between the ejection mechanism 22 and the fire-fighting activation mechanism 23. This means that the power is cut off and the socket is sealed before the fire-fighting medium is sprayed. This helps to extinguish fires in a relatively sealed environment, improves the utilization rate of the fire-fighting medium, and thus enhances the effectiveness of the overall fire response. It also reduces the risk of accidental discharge of the fire-fighting medium.

[0035] Furthermore, the ejection mechanism 22 includes a sliding plate 32 and multiple guide rods 30. The multiple guide rods 30 are fixed on the inner wall of the housing 11 and located on the outer periphery of the external socket 12. The external socket 12 has a protective socket 47 and two power sockets 46. The sliding plate 32 is slidably sleeved on the guide rods 30. A tension spring 31 is sleeved on the guide rods 30. The two ends of the tension spring 31 are respectively fixedly connected to the sliding plate 32 and the housing 11. A first hanging ring 33 is fixedly installed on the end of the sliding plate 32 away from the tension spring 31. The first hanging ring 33 is slidably hung in the first inner ring groove 25. A push foot 34 is fixedly installed on the end of the sliding plate 32 away from the first hanging ring 33. A frustum-shaped seal is provided at the root of the push foot 34. The frustum-shaped seal is made of high-temperature resistant silicone rubber. The size of the frustum-shaped seal is larger than the outer periphery of the push foot 34. The push foot 34 can be detachably inserted into the protective socket 47 and the power socket 46.

[0036] The tension spring 31 fitted on the guide rod 30 is connected to the slide plate 32 and the housing 11 at both ends. Under normal conditions, the tension spring 31 is in a stored state, providing elastic potential energy for rapid ejection after triggering.

[0037] A first hanging ring 33 is fixed at one end of the slide plate 32. The first hanging ring 33 is slidably hooked into the first inner ring groove 25 of the first hook plate 20. When the rotating rod 18 rotates to the point where the through opening of the first hook plate 20 is aligned with the first hanging ring 33, the first hanging ring 33 is dislodged, and the tension spring 31 releases its elastic potential energy to drive the slide plate 32 to slide rapidly.

[0038] The push foot 34 fixed at the other end of the slide plate 32 can normally be inserted separately into the protection socket 47 and the two power sockets 46. When triggered, the push foot 34 will push out the protection socket 45 and the power socket 44 inserted in each socket simultaneously to achieve rapid power cut-off.

[0039] The truncated pyramid-shaped seal at the base of the push foot 34, with its outer circumference larger than that of the push foot 34, forms an embedded seal on the protection socket 47 and the power socket 46 after the push foot 34 has fully pushed out the plug. The high-temperature resistant silicone rubber material allows the seal to maintain good sealing performance even in the high-temperature environment of a fire, which helps to create a relatively sealed space for the subsequent spraying of fire-fighting media and improves the fire extinguishing effect.

[0040] Furthermore, power contact springs 41 are fixedly installed on the outer sides of the two power sockets 46, and the two power contact springs 41 are respectively connected to the corresponding phase wires through conductors 40; a sliding groove 36 with directional depth is opened on the housing between the two power contact springs 41, and the protective socket 47 is located inside the sliding groove 36; a mouth-shaped slide 35 is slidably installed inside the sliding groove 36, and compression springs 42 are fixedly installed on both ends of the mouth-shaped slide 35 near the power sockets 46; two protective springs 43 are fixedly installed inside the mouth-shaped slide 35, and the two protective springs 43 are located on both sides of the protective socket 47 and away from the compression springs 42, and the protective springs 43 are connected to the corresponding phase wires through flexible wires; limiting components are provided on both sides of the mouth-shaped slide 35, and a second tension spring 37 is fixedly installed on the end of the mouth-shaped slide 35 away from the power sockets 46, and the other end of the second tension spring 37 is connected to a fixing plate, which is fixed on the inner wall of the housing 11.

[0041] Under normal conditions, the slit carriage 35 is kept close to the power socket 46 under the constraint of the limiting component. At this time, the compression springs 42 fixed at both ends of the slit carriage 35 near the power contact springs 41 and the power contact springs 41 together form a double spring clamp for the power pins 44. The two protective springs 43 fixed inside the slit carriage 35 are located on both sides of the protective socket 47 and clamp the protective pins 45. Under the clamping of the springs, each pin maintains stable electrical contact with the corresponding conductor 40 and phase wire, ensuring the reliability of the power connection.

[0042] Under normal conditions, the second tension spring 37 is in a stored state, providing elastic potential energy for the rapid displacement of the subsequent mouth-shaped slide 35.

[0043] When the fire triggers the ejection mechanism 22, the push foot 34 first triggers the limiting component before ejecting the plug. The limiting component releases the constraint on the mouth-shaped slide 35, and the second tension spring 37 releases its elastic potential energy to drive the mouth-shaped slide 35 to slide rapidly away from the power socket 46. The compression spring 42 then disengages from the clamping position of the power plug 44, and the protection spring 43 moves away from the protection plug 45 at the same time, so that the clamping force of the spring at each plug is released. After that, the push foot 34 can push the power plug 44 and the protection plug 45 out of the corresponding socket more smoothly, which helps to reduce the resistance during the ejection process and reduce the impact of poor ejection caused by excessive clamping force.

[0044] The design of the protective spring 43 being connected to the corresponding phase line via a flexible wire ensures that the wire connection remains flexible and adaptable during the sliding of the spherical slide 35, preventing the rigid connection from interfering with the sliding action.

[0045] Furthermore, the limiting component includes two upright plates 38 fixed to the housing 11, with the two upright plates 38 located on both sides of the slide groove 36 respectively. An inverted L-shaped plate 39 is fixed to the top of the upright plate 38, and the vertical plate of the L-shaped plate 39 is slidably fastened to the inner wall of the mouth-shaped slide 35. The horizontal plate of the L-shaped plate 39 is fixedly connected to the top of the vertical plate 38; the two L-shaped plates 39 have through guide grooves 54, and tongue rods 48 are slidably arranged in the guide grooves 54 respectively. The two tongue rods 48 are arranged opposite each other and their inclined surfaces face the push foot 34; a widening groove is opened in the guide groove 54 at the end away from the mouth-shaped carriage 35, and an end cap 55 is fixed in the widening groove; wing plates 49 are fixed on both sides of the tongue rods 48 respectively, and the wing plates 49 slide in the widening groove. A return spring 50 is set between the wing plates 49 and the end cap 55; a limiting protrusion 51 is fixed at the bottom end of the tongue rods 48, and a guide groove 52 is opened on the vertical plate 38. The limiting protrusion 51 slides in the guide groove 52; a limiting groove 53 is opened on both sides of the mouth-shaped carriage 35 corresponding to the guide groove 52, and the limiting protrusion 51 can be detachably extended into the limiting groove 53.

[0046] Under normal conditions, the limiting component locks the mouth-shaped carriage 35 through the cooperation of the tongue rod 48 and the limiting protrusion 51.

[0047] The limiting protrusion 51 fixed at the bottom of the tongue rod 48 slides in the guide groove 52 on the upright plate 38 and can be separated into the corresponding limiting grooves 53 on both sides of the mouth-shaped slide 35. It is this limiting protrusion 51 that extends into the limiting groove 53 that locks the mouth-shaped slide 35, so that the second tension spring 37 remains in a stored state under normal conditions and does not trigger sliding.

[0048] When the push foot 34 moves toward the socket, it first contacts the inclined surface of the two tongues 48 facing itself, and applies a lateral force along the inclined surface to the tongues 48, driving the two tongues 48 to slide outwards. The wing plate 49 slides synchronously in the widened groove and compresses the return spring 50. After the tongues 48 are laterally displaced, the limiting protrusion 51 at the bottom slides in the guide groove 52 and exits the limiting groove 53. The locking of the mouth-shaped slide 35 is released, and the second tension spring 37 releases its elastic potential energy to drive the mouth-shaped slide 35 to slide rapidly away from the power socket 46. The compression spring 42 and the protective spring 43 simultaneously disengage from the clamping of each pin, allowing the push foot 34 to push out the power pin 44 and the protective pin 45 more smoothly.

[0049] After the push foot 34 leaves the inclined surface of the tongue rod 48, the return spring 50 pushes the wing plate 49 to drive the tongue rod 48 to reset, and the limiting protrusion 51 returns to the initial position of the guide groove 52, providing a structural basis for the subsequent maintenance and reset of the device.

[0050] The limiting component achieves precise timing of clamp release driven by the action of the push foot 34 through the coordinated action of inclined trigger, elastic reset and convex locking. This helps to reduce resistance during the push-out process and improve the reliability of the ejection mechanism 22.

[0051] Furthermore, the fire-fighting opening mechanism 23 includes a guide frame 59 and two guide rods 57. The two guide rods 57 are fixed on the inner side wall of the housing 11. The guide frame 59 includes two side plates, which are slidably sleeved on the guide rods 57. A third tension spring 58 is sleeved on the guide rods 57, and the two ends of the third tension spring 58 are fixedly connected to the housing 11 and the side plates, respectively. A second hanging ring 56 is fixedly installed at one end of the guide frame 59 away from the third tension spring 58. The second hanging ring 56 is slidably hooked in the second inner ring groove of the second hook plate 21. A lever assembly is provided on the side of the guide frame 59 away from the second hanging ring 56. The lever 60 of the lever assembly abuts against the push rod 24 of the angle valve.

[0052] Two guide rods 57 are fixed on the inner wall of the housing 11 to provide stable sliding guidance for the two side plates of the guide frame 59, so that the movement direction of the guide frame 59 is consistent with the axial direction of the push rod 24, which helps to ensure that the abutment action of the lever 60 against the push rod 24 is accurate and reliable.

[0053] The third tension spring 58, which is fitted on the guide rod 57, is connected at both ends to the housing 11 and the side plate of the guide frame 59, respectively. Under normal conditions, the third tension spring 58 is in a stored state, providing elastic potential energy for the rapid displacement of the guide frame 59 after triggering.

[0054] A second hanging ring 56 is fixed at the end of the guide frame 59 away from the third tension spring 58. The second hanging ring 56 is slidably hooked into the second inner ring groove of the second hook plate 21. Constrained by the three-quarters arc of the second inner ring groove, the fire-fighting opening mechanism 23 remains locked in the initial stage of the rotation of the rotating rod 18. After the rotating rod 18 has rotated through a sufficient angle, the through opening is aligned with the second hanging ring 56, and the second hanging ring 56 can be disengaged. The third tension spring 58 then releases its elastic potential energy to drive the guide frame 59 to slide rapidly. The lever assembly on the side of the guide frame 59 away from the second hanging ring 56 is linked accordingly. The lever 60 abuts against and moves the angle valve push rod 24 to open the fire-fighting medium passage and trigger the sprinkler head 17 to spray the fire-fighting medium to extinguish the fire.

[0055] This delayed triggering sequence allows the fire-fighting activation mechanism 23 to be activated only after the ejector mechanism 22 has completed the insertion of the pins and the sealing of the socket. This helps the fire-fighting medium to be sprayed in a relatively sealed environment, thereby improving the utilization efficiency of the fire-fighting medium; it also reduces the risk of accidental spraying of the fire-fighting medium.

[0056] Furthermore, the lever assembly includes a double-mouth frame 65 spaced apart, the double-mouth frame 65 is fixed on the guide frame 59, a lever 60 passes through the middle of the double-mouth frame 65, one end of the lever 60 extends close to the push rod 24, and the other end of the lever 60 is vertically provided with a crossbar 63, the two ends of the crossbar 63 slide in the grooves on both sides of the double-mouth frame 65; a pin 61 is fixed on the lever 60, the pin 61 is located at the end close to the push rod 24; a double-row support rod 62 is fixed on the housing 11, and the pin 61 is rotatably installed in the support rod 62.

[0057] The lever assembly uses leverage to actuate and open the push rod 24. The double-mouth frame 65 is fixedly mounted on the guide frame 59 at intervals, providing a stable mounting frame for the lever 60. The lever 60 passes through the middle of the double-mouth frame 65, with one end extending close to the push rod 24 and the other end vertically fixed to the crossbar 63. The two ends of the crossbar 63 slide in the grooves on both sides of the double-mouth frame 65, guiding and limiting the swing range of the lever 60, so that the lever 60 maintains a stable planar swing posture during movement.

[0058] The pin 61 fixed on the lever 60 is rotatably mounted in the double-row support rod 62 on the housing 11. The pin 61 serves as the rotation fulcrum of the lever 60, and the double-row support rod 62 clamps and supports the pin 61 from both sides, which helps to enhance the structural stability at the fulcrum and reduce the possibility of the lever 60 deviating or shaking during the force-driven movement.

[0059] When the fire-fighting opening mechanism 23 is triggered, the driving force acts on one side of the crossbar 63, and the lever 60 rotates with the pin 61 as the fulcrum. The end near the push rod 24 swings towards the push rod 24, applying a pushing force to the push rod 24, thereby opening the fire-fighting medium angle valve.

[0060] The introduction of the lever principle amplifies the driving force to a certain extent, which helps to overcome the initial resistance required for the angle valve to open, reduces the negative impact of obstructed fire-fighting medium flow caused by poor angle valve opening, and ensures the smooth spraying of fire-fighting medium.

[0061] Furthermore, the lever 60 extends through the entire length of the lever 60, and an extension rod 66 is slidably fitted inside the lever 60. One end of the extension rod 66 is fixedly connected to a crossbar 63, and a ratchet 67 is provided on the extension rod 66. A through-hole 68 is provided on one side wall of the lever 60, and two guide rods are fixed outside the through-hole 68. A top plate 69 is fixed at the end of the two guide rods. A pressure plate is slidably fitted on the guide rod, and a ratchet 71 is fixed at the bottom end of the pressure plate. The ratchet 71 and the ratchet 67 cooperate to form a one-way lock. A return spring 70 is fitted on the guide rod, and the two ends of the return spring 70 are respectively connected to the pressure plate and the top plate 69.

[0062] Under normal conditions, the return spring 70 pushes the pressure plate to keep the ratchet 71 engaged with the ratchet 67, forming a one-way lock on the extension rod 66, so that the extension rod 66 can only move in the extension direction and cannot retract.

[0063] When the fire-fighting activation mechanism 23 is triggered, the guide frame 59 drives the lever assembly to move, and the lever 60 rotates on the principle of leverage and abuts against the push rod 24.

[0064] During the rotation of lever 60 around pin 61, crossbar 63 is subjected to the reverse thrust from the top of double-mouth bracket 65, causing extension rod 66 to slide outward along the inner cavity of lever 60. The one-way locking structure of ratchet 71 and ratchet 67 locks the extension rod 66 after it extends a certain amount, preventing it from retracting due to elastic rebound. As the extension rod 66 extends, the contact range between crossbar 63 and push rod 24 continues to increase, further increasing the opening angle of diagonal valve.

[0065] This ratchet extension design helps maintain a large actuation stroke even when the contact area of ​​the angle valve push rod 24 is reduced, thereby reducing the negative impact of poor angle valve opening on the flow of fire-fighting media and improving the reliability of fire-fighting media release.

[0066] The return spring 70 releases the ratchet 71 from the ratchet 67 by pressing down the pressure plate with external force during device maintenance and reset, allowing the extension rod 66 to return to its initial position, thus providing structural conditions for the repeated use of the device.

[0067] Furthermore, when an external plug is connected to the external connector 12, the protective pin 45 of the external plug extends into the protective connector 47, and the power pin 44 of the external plug extends into the power connector 46, and respectively contacts the corresponding contact spring.

[0068] When the external plug is connected to the external socket 12, the protective pin 45 extends into the protective socket 47, and the power pins 44 extend into the two power sockets 46 respectively. Each pin forms a stable elastic contact with the corresponding contact spring, achieving a reliable power connection. The protective pin 45 contacts the protective spring 43 and is connected to the corresponding phase line through a flexible wire. The power pin 44 contacts the power contact spring 41 and is connected to the corresponding phase line through a conductor 40, forming a complete power circuit.

[0069] At the same time, under normal conditions, the compression spring 42 on the side of the mouth-shaped carriage 35 near the power socket 46 and the power contact spring 41 together form a double spring clamp for the power plug 44, and the protection spring 43 clamps the protection plug 45. Under the action of the spring clamping force, each plug maintains close contact with the corresponding spring, which helps to reduce contact resistance and reduce electrical hazards caused by poor contact, thereby improving the stability and safety of the power connection of the external socket 12 under normal use.

[0070] The compression spring 42 can also be connected to the corresponding phase conductor via a flexible wire to reduce resistance.
