Description

Technical Field

[0002] With the promotion and application of new energy sources such as solar energy and wind energy, energy storage technology has also developed. Lithium batteries have gradually become the mainstream product of energy storage due to their advantages of high energy, long service life, high rated voltage, high power tolerance, low self-discharge rate, light weight, green environmental protection, and almost no water consumption in production. However, the charge and discharge cycle life and safety of lithium-ion batteries are greatly affected by temperature. When the battery cell temperature is too high or the temperature difference is large, the battery cell cycle life will be greatly reduced, affecting the service life of the energy storage product. In severe cases, it will cause thermal runaway of the battery cell. Therefore, it is necessary to set up supporting fire-fighting facilities in the environment where lithium batteries are used. In order to carry out fire-fighting treatment of lithium batteries in time, it is usually adopted to set fire sprinklers in the battery box. However, the existing fire sprinkler locking method needs to be inserted into the equipment through the installation hole during on-site installation. During the process, it is impossible to observe the inside of the equipment, so it is impossible to determine the direction of the sprinkler, which is easy to cause the inability to effectively spray the agent into the space when thermal runaway occurs, thereby greatly reducing the fire extinguishing efficiency.

[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0037] Please refer to Figures 1 to 7 , a foolproof glass bubble nozzle, comprising a mounting mechanism, a thermal breaking mechanism and a joint mechanism;

[0038] The mounting mechanism comprises a connection seat 4 with a through hole, the inner wall of the connection seat 4 is provided with a first fool-proofing portion 44, the outer wall of the connection seat 4 is provided with a second fool-proofing portion 45, and the positions of the first fool-proofing portion 44 and the second fool-proofing portion 45 match;

[0039] The thermal breaking mechanism comprises a nozzle housing 1, the nozzle is inserted into the through hole of the connecting seat 4 and the open end of the nozzle housing 1 is embedded in the inner wall of the connecting seat 4, and the outer wall of the nozzle housing 1 is provided with a third foolproof portion 11, and the third foolproof portion 11 matches the structure of the first foolproof portion 44;

[0040] The joint mechanism comprises a joint connector 7 provided with a through hole, and the joint connector 7 is assembled and connected with the open end of the nozzle housing 1 .

[0041] From the above description, it can be seen that the beneficial effect of the utility model is that: by respectively arranging a first anti-mistake portion 44 and a third anti-mistake portion 11 with matching structures on the connecting seat 4 inside the nozzle and the nozzle shell 1, when the nozzle is installed, the nozzle shell 1 with the function of spraying medicine is installed in a directional manner, and when the nozzle and the connecting plate are subsequently installed, the second anti-mistake portion 45 cooperates with the corresponding assembly hole to determine the orientation of the nozzle in the installation space, so that the direction of the agent spraying is in line with expectations, thereby ensuring the fire extinguishing effect.

[0042] It should be noted that glass ball sprinklers are generally used for fire prevention and control at fixed locations. The principle is: a thermosensitive glass ball 2 is set to block the nozzle 12 of the sprinkler. When the temperature reaches a preset threshold, the thermosensitive glass ball 2 breaks, thereby transporting the fire extinguishing agent to the space originally occupied by the thermosensitive glass ball 2 and spraying it according to the position of the sprinkler.

[0043] Furthermore, the connection seat 4 is provided with a first column section 41 and a second column section 42 which are coaxially connected, the inner diameter of the first column section 41 is smaller than the inner diameter of the second column section 42; the outer diameter of the first column section 41 is smaller than the outer diameter of the second column section 42;

[0044] The inner wall of the first column section 41 is provided with a first fool-proof portion 44 and the outer wall of the first column section 41 is provided with a second fool-proof portion 45;

[0045] The open end of the nozzle housing 1 is engaged with the inner wall of the second column section 42 .

[0046] From the above description, it can be known that in order to achieve effective fixation of the nozzle housing 1, the connecting seat 4 is provided with a first column section 41 and a second column section 42 which are coaxially connected. The inner and outer diameters of the first column section 41 are smaller than those of the second column section 42, so that when the nozzle housing 1 is inserted into the through hole of the connecting seat 4, the open end of the nozzle housing 1 can be snapped onto the inner wall of the second column section 42; at the same time, the first anti-foolproofing portion 44 and the second anti-foolproofing portion 45 are respectively arranged on the inner and outer walls of the first column section 41. When the nozzle itself is assembled, the nozzle housing 1 is inserted into the second column section 42 and extended from the first column section 41. The third anti-foolproofing portion 11 and the first anti-foolproofing portion 44 automatically cooperate to achieve positioning between the connecting seat 4 and the nozzle housing 1, thereby simplifying the assembly process.

[0047] Furthermore, the connecting seat 4 also includes a third column segment 43, the first column segment 41, the second column segment 42 and the third column segment 43 are coaxially connected in sequence, the inner diameter of the third column segment 43 is larger than the inner diameter of the second column segment 42, and the joint connector 7 is clamped with the inner wall of the third column segment 43.

[0048] From the above description, it can be seen that the third column section 43 is coaxially arranged after the second column section 42, and the inner diameter of the third column section 43 is larger than the inner diameter of the second column section 42, that is, the inner diameters of the first column section 41, the second column section 42 and the third column section 43 increase successively, and the internal cross-section of the connecting seat 4 is stepped, and the stepped setting is used to clamp the various components respectively, wherein the second column section 42 clamps the open end of the nozzle housing 1, and the third column section 43 clamps the joint connector 7, and at the same time, the joint connector 7 is assembled and connected with the open end of the nozzle housing 1, so that the stepped structure of the connecting seat 4 is used to limit the components during assembly, thereby simplifying the assembly process.

[0049] Furthermore, the mounting mechanism further comprises a locking nut 8 , which is threadedly connected to the outer wall of the third column section 43 and is used to limit the joint connector 7 .

[0050] From the above description, it can be seen that in order to achieve structural stability of the components of the entire nozzle, a locking nut 8 is provided outside the third column section 43 to limit the joint connector 7, thereby fixing the joint connector 7 on the connection seat 4. At the same time, the provision of the locking nut 8 facilitates the disassembly of the nozzle structure, and then facilitates the replacement of the internal structure.

[0051] Furthermore, the thermal breaking mechanism also includes a thermal glass ball 2 and a plug rod 3; the two ends of the thermal glass ball 2 are respectively abutted against the inner wall of the nozzle shell 1 and the plug rod 3, and the end of the plug rod 3 away from the thermal glass ball 2 is elastically connected to the joint connector 7; the nozzle shell 1 is provided with a nozzle 12 in a section close to the thermal glass ball 2.

[0052] From the above description, it can be seen that a nozzle structure is provided. Through the arrangement of the plug rod 3 and the thermosensitive glass ball 2, when the thermosensitive glass ball 2 is intact, the fire extinguishing agent cannot be output due to the position of the plug rod 3 blocking the nozzle 12. Subsequently, when the thermosensitive glass ball 2 is broken, the plug rod 3 is elastically acted upon by the joint connector 7 and rebounds to the space originally occupied by the thermosensitive glass ball 2, thereby connecting the nozzle 12 and realizing the spraying of the fire extinguishing agent.

[0053] Specifically, the joint mechanism also includes a spring 9, which is arranged in the through hole of the joint connector 7 and abuts against the plug rod 3 and the inner wall of the joint connector 7 respectively, thereby ensuring that the plug rod 3 is under the elastic force of the spring 9.

[0054] Furthermore, the cross sections of the first fool-proofing portion 44 , the second fool-proofing portion 45 and the third fool-proofing portion 11 are all D-shaped cross sections.

[0055] From the above description, it can be seen that in order to simplify the anti-foolproofing structure, the first anti-foolproofing part 44, the second anti-foolproofing part 45 and the third anti-foolproofing part 11 uniformly adopt a D-shaped cross-section, that is, a cut is set on the original circular cross-section, and the plane generated by the cut is used to implement the anti-foolproofing effect.

[0056] Please refer to Figures 1 to 7 An assembly assembly includes an anti-foolproof glass bubble nozzle and an assembly plate 10, wherein the assembly plate 10 is provided with an assembly hole matching the second anti-foolproof portion 45, and the connecting seat 4 is passed through the assembly hole and assembled and connected with the assembly plate 10.

[0057] From the above description, it can be seen that after the nozzle itself is assembled, the second anti-mistake portion 45 cooperates with the corresponding assembly hole to determine the orientation of the nozzle in the installation space, so that the agent spraying direction meets the expectation and ensures the fire extinguishing effect.

[0058] Furthermore, it also includes an assembly nut 5 , which is threadedly connected to the first column section 41 , and the assembly nut 5 and the second column section 42 are respectively pressed against the assembly plate 10 .

[0059] From the above description, it can be seen that since the outer diameter of the second column segment 42 is larger than the outer diameter of the first column segment 41, after the second anti-misalignment portion 45 is inserted into the assembly hole to complete the positioning, the assembly plate 10 is clamped and fixed using the assembly nut 5 and the outer wall of the second column segment 42, thereby simplifying the assembly process between the nozzle and the installation facility.

[0060] Furthermore, it also includes a sealing gasket 6, which is sleeved on the flat area of ​​the first column section 41 and is respectively pressed against the assembly plate 10 and the second column section 42.

[0061] From the above description, it can be seen that a sealing gasket 6 is arranged between the assembly plate 10 and the second column section 42 to improve the sealing effect. At the same time, the sealing gasket 6 is arranged in a flat area of ​​the first column section 41 to avoid obstruction by sharp objects or threads and breakage of the sealing gasket 6 when excessive torque is applied, thereby improving the service life of the sealing gasket 6 and improving construction safety.

[0065] Please refer to Figures 1 to 7 , Embodiment 2 of the present utility model is:

[0066] On the basis of the first embodiment, the connection seat 4 is provided with a first column section 41 and a second column section 42 which are coaxially connected. The inner diameter of the first column section 41 is smaller than the inner diameter of the second column section 42; the outer diameter of the first column section 41 is smaller than the outer diameter of the second column section 42; the inner and outer diameters of the first column section 41 are both smaller than the second column section 42, so that when the nozzle housing 1 is inserted into the through hole of the connection seat 4, the open end of the nozzle housing 1 can be snapped into the inner wall of the second column section 42; the inner wall of the first column section 41 is provided with a first foolproof portion 44 and the outer wall of the first column section 41 is provided with a second foolproof portion 45; the open end of the nozzle housing 1 is snapped into the inner wall of the second column section 42.

Through the arrangement of the plug rod 3 and the thermal glass ball 2, when the thermal glass ball 2 is in good condition, the fire extinguishing agent cannot be output because the position of the plug rod 3 blocks the nozzle 12. After the thermal glass ball 2 is broken, the plug rod 3 is elastically acted on by the joint connector 7 to bounce to the space originally occupied by the thermal glass ball 2, thereby making the nozzle 12 conductive and realizing the spraying of the fire extinguishing agent.
