Description

Technical Field

[0001] This application relates to the field of fire protection technology, and in particular to a fire pipeline testing device and a fire pipeline testing system for lithium battery charging and discharging equipment. Background Technology

[0002] Lithium-ion battery charging and discharging equipment includes mechanical units for the formation and capacity testing of lithium-ion batteries, as well as fire-fighting pipes. The formation and capacity testing process is a key step in lithium-ion battery manufacturing, primarily used to activate the battery and determine its initial capacity and performance. During this process, the internal chemical reactions of the battery cell are complex, which may lead to a series of problems such as heat accumulation, electrolyte leakage, and short circuits, potentially causing safety accidents such as fires or even explosions.

[0003] However, due to prolonged disuse, fire-fighting pipes may become clogged, rendering them unusable. Therefore, there is an urgent need to design a detection device capable of detecting internal blockages in fire-fighting pipes. Utility Model Content

[0004] This utility model discloses a fire pipeline blockage detection device, which can detect internal blockage problems in fire pipelines and improve the fault tolerance of the connection between the fire pipeline detection device and the sprinkler head of the fire pipeline.

[0005] To achieve the above objectives, the first aspect of this utility model discloses a fire pipeline testing device, comprising:

[0006] A connecting member, wherein an air duct is formed inside the connecting member, the air duct having a gas inlet and a gas outlet that are opposite to and connected in a first direction, the gas inlet being flared out in the first direction relative to the gas outlet, and the gas inlet being configured to allow a sprinkler head of a fire pipe to extend into it, so that the sprinkler head of the fire pipe is located inside the air duct.

[0007] A test piece connected to the gas outlet, the test piece being configured to detect the flow rate and / or velocity of gas introduced into the duct via the fire hydrant as it exits the gas outlet.

[0008] As an optional implementation, the fire pipeline inspection device further includes a support member, and the docking member is rotatably mounted on the support member.

[0009] This ensures that the gas inlet can be more accurately aligned with the sprinkler head, thus enabling the fire pipeline testing device to adapt to various fire pipeline sprinkler heads and improving its versatility.

[0010] As an optional implementation, the support member includes two spaced-apart support portions, each support portion having a first shaft connection portion, and the docking member having a second shaft connection portion corresponding to the first shaft connection portion. The second shaft connection portion is disposed close to the gas outlet along the first direction, and the second shaft connection portion is shafted to the first shaft connection portion, so that the docking member is rotatable relative to the support portion.

[0011] The support member includes two spaced-apart support parts. The first shaft connection on the support part and the corresponding second shaft connection on the docking member are shafted together, so that the docking member can rotate relative to the support part. The rotation direction of the support part intersects with the gas flow direction (first direction). This allows the docking member to be adjusted in multiple directions on a plane perpendicular to the gas flow direction, thereby adapting to different sprinkler head installation positions, ensuring that the gas from the sprinkler head can accurately enter the air duct, and thus improving the detection accuracy of the fire pipeline detection device.

[0012] As an optional implementation, the fire pipeline detection device further includes a first drive mechanism connected to the docking member, the first drive mechanism being configured to drive the docking member to move along the first direction to approach or move away from the sprinkler head of the fire pipeline.

[0013] The fire pipeline detection device further includes a second drive mechanism, which is connected to the docking member. The second drive mechanism is configured to drive the docking member to move along a second direction, so that the position of the docking member relative to the sprinkler head of the fire pipeline along the second direction is adjustable.

[0014] The second direction intersects with the first direction.

[0015] In this way, the first and second drive mechanisms respectively drive the docking component to move along the first direction (gas flow direction) and the second direction (direction intersecting with the first direction). The coordinated operation of the two drive mechanisms allows the docking component to automatically align with the sprinkler head. On the one hand, this reduces the risk of errors or malfunctions caused by improper manual operation, ensuring that the sprinkler head can accurately extend into the gas inlet. On the other hand, the first and second drive mechanisms can quickly move and adjust the position of the docking component, making the fire pipe blockage detection process more efficient.

[0016] As an optional implementation, the fire pipeline testing device further includes a carrier, on which the docking part and the test piece are both disposed. The first driving mechanism is connected to the carrier and is configured to drive the carrier to move along the first direction, so as to drive the docking part and the test piece to move simultaneously along the first direction.

[0017] The carrier, the docking component, and the test component constitute a test unit.

[0018] In this way, the synchronous movement of the docking part and the test piece ensures that when the docking part is aligned with the fire sprinkler head, the test piece is also in a suitable position relative to the gas outlet, reducing the time required to adjust the position between the docking part and the test piece, and making the testing process more efficient.

[0019] As an optional implementation, the fire pipeline testing device further includes an adjustment component configured to adjust the position of the support plate in a third direction to adjust the position of two adjacent test units in the third direction.

[0020] The adjustment assembly includes a fixed base and an elastic element. The fixed base is located on one side of the support member along the third direction and is connected to the first drive mechanism. The elastic element is connected to the fixed base and the support member along the third direction. The support member can squeeze the elastic element along the third direction to adjust the position of the test unit in the third direction.

[0021] The third direction intersects with both the first direction and the second direction.

[0022] Even if there is a certain distance error between the sprinkler head and the connecting part along the third direction on the fire pipe, the distance error between the sprinkler head and the connecting part can be automatically compensated by the adjustment component, thereby ensuring the precise alignment of the connecting part and the sprinkler head.

[0023] Secondly, the fixed base provides a stable fulcrum for the elastic element, ensuring the reliability of the adjustment assembly. Furthermore, the buffering and reset functions of the elastic element allow the carrier to move and reset along a third direction, enabling it to return to its initial position after being subjected to external force. This facilitates rapid docking of the next component with the next spray head, achieving automation and continuity in the testing process, thereby improving testing efficiency.

[0024] As an optional implementation, the fire pipeline testing device includes multiple test units, which are arranged at least at intervals along the third direction and upward along the third direction, with adjacent test units connected by connectors.

[0025] The fixed base is disposed on the connector, and the first driving mechanism is connected to the connector. The first driving mechanism is configured to drive the connector to move along the first direction, so as to drive the two adjacent test units to move simultaneously along the first direction to approach or move away from the sprinkler head of the fire pipe.

[0026] In this way, when the first drive mechanism drives the connecting parts to move along the first direction, it can simultaneously drive multiple test units along the third direction to move closer to or further away from the sprinkler heads of the fire pipe. This allows the fire pipeline testing device to simultaneously connect multiple sets of connecting parts and sprinkler heads in one drive operation of the first drive mechanism, thereby improving the testing efficiency of the fire pipeline testing device.

[0027] As an optional implementation, the fire pipeline inspection device further includes a guide mechanism disposed on the connector and extending along the third direction. The carrier is slidably connected to the guide mechanism along the third direction, and the guide mechanism is configured to guide the movement of the carrier along the third direction.

[0028] This provides precise guidance for the movement of the carrier in the third direction, thereby ensuring that the carrier moves along the predetermined track and avoiding movement errors caused by offset or swaying.

[0029] As an optional implementation, the carrier, the docking member, and the test piece constitute a test unit, and the fire pipeline testing device includes multiple test units;

[0030] The fire pipeline testing device also includes a lifting plate. The second drive mechanism is disposed below the lifting plate along the second direction. The second drive mechanism is connected to the lifting plate and is configured to drive the lifting plate to move along the second direction, so as to drive multiple test units to move simultaneously along the second direction.

[0031] In this way, multiple test units share a single second drive mechanism, reducing the number of drive mechanisms required. This reduces the manufacturing cost of the fire pipeline testing device and enables synchronous control of multiple test units, thereby improving the testing efficiency of the fire pipeline testing device.

[0032] As an optional implementation, the fire pipeline detection device further includes a first sensor disposed on the docking member, the first sensor being configured to detect the movement position of the docking member along the first direction, and the first drive mechanism being configured to start or stop driving the docking member to move along the first direction according to the movement position of the docking member along the first direction.

[0033] The fire pipeline detection device further includes a second sensor, which is disposed on the docking member and configured to detect the movement position of the docking member along the second direction. The second drive mechanism is configured to start or stop driving the docking member to move along the second direction based on the movement position of the docking member along the second direction.

[0034] By setting up a first sensor and a second sensor to monitor the position of the docking component in the first and second directions in real time, the docking component can be made to move closer to or further away from the sprinkler head, thereby improving the docking accuracy between the fire pipeline detection device and the fire pipeline sprinkler head.

[0035] Secondly, this application also discloses a fire-fighting pipeline testing system for lithium battery charging and discharging equipment, including a mechanical unit, a fire-fighting pipe, and a fire-fighting pipeline testing device as described in the first aspect above. The fire-fighting pipe is disposed on the mechanical unit. When the fire-fighting pipeline testing device is pushed into the mechanical unit, the docking part of the fire-fighting pipeline testing device is configured to dock with the sprinkler head of the fire-fighting pipe, so that when the test piece is introduced into the fire-fighting pipe, the flow rate and / or velocity of the gas sprayed from the sprinkler head of the fire-fighting pipe can be detected.

[0036] Compared with the prior art, the beneficial effects of this application are:

[0037] This utility model provides a fire-fighting pipeline testing device and a lithium battery charging and discharging equipment fire-fighting pipeline testing system. By setting a connecting member, a duct is formed inside the connecting member with a gas outlet and a gas inlet that are opposite and connected along a first direction. The gas inlet is flared out relative to the gas outlet along the first direction, allowing the sprinkler head of the fire-fighting pipe to extend into it, so that the sprinkler head is located within the duct. A test piece is connected to the gas outlet and is used to detect the flow rate and / or velocity of the gas entering the duct through the fire-fighting pipe and exiting through the gas outlet. Using the fire-fighting pipeline testing device of this application, the connecting member can be connected to the sprinkler head of the fire-fighting pipe, allowing the sprinkler head to extend into the gas inlet of the connecting member and thus be located within the duct inside the connecting member. Furthermore, the test piece connected to the gas outlet allows the test piece to detect the flow rate and / or velocity of the gas entering the duct through the fire-fighting pipe and exiting through the gas outlet, thereby enabling the detection of blockages within the fire-fighting pipe.

[0038] Furthermore, this application also features a flared gas inlet on the connecting piece relative to the gas outlet along the first direction, allowing the sprinkler head of the fire pipe to be located within the duct. This flared duct design ensures that even if the sprinkler head's position deviates, it can still extend into the duct of the connecting piece when the connecting piece is connected to the sprinkler head of the fire pipe. This ensures that the gas can be effectively captured and measured, thereby improving the connection tolerance between the fire pipe detection device and the fire pipe sprinkler head.

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated equipment, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0051] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0052] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0053] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0054] Formation and capacity grading are crucial steps in lithium battery production. Formation refers to the initial charging process after battery assembly. During this process, the electrode materials inside the battery undergo a series of chemical reactions with the electrolyte, forming a stable electrode-electrolyte interface. Capacity grading refers to the process of classifying batteries according to performance indicators such as capacity and internal resistance through a series of charge-discharge tests after formation.

[0055] During the formation and capacity testing process, lithium batteries, due to their high energy density, are prone to thermal runaway caused by external factors such as overcharging, short circuits, and high temperatures, or by internal material defects. This can easily lead to fires or even explosions. Therefore, fire suppression pipes are usually installed in the formation and capacity testing equipment for timely fire extinguishing. However, if these fire suppression pipes are not used for extended periods, blockages may occur inside, rendering them unusable.

[0056] In related technologies, to detect blockages in fire-fighting pipes, an airtightness tester is typically connected to the outside of the pipe. The connection between the airtightness tester and the fire-fighting pipe sprinkler head is usually achieved by setting an annular groove inside the test end of the tester. This annular groove contains multiple limiting ports. The sprinkler head is inserted into the annular groove and rotated, and the limiting ports restrict the movement of the sprinkler head, thus achieving docking between the airtightness tester and the fire-fighting pipe sprinkler head. This method requires high precision in docking and is difficult to operate.

[0057] In view of this, this application discloses a fire-fighting pipeline testing device and a lithium battery charging and discharging equipment fire-fighting pipeline testing system. The device includes a connecting member that forms an air duct with a gas inlet and a gas outlet that are opposite and connected along a first direction. The gas inlet is configured for the sprinkler head of the fire-fighting pipe to extend into, so that the sprinkler head is located within the air duct. A test piece is connected to the gas outlet, and the test piece can detect the flow rate and / or velocity of the gas entering the air duct through the fire-fighting pipe and exiting through the gas outlet. The fire-fighting pipeline testing device of this application can connect the connecting member to the sprinkler head of the fire-fighting pipe, allowing the sprinkler head to extend into the gas inlet of the connecting member and thus be located within the air duct inside the connecting member. Furthermore, the test piece is connected to the gas outlet, enabling the test piece to detect the flow rate and / or velocity of the gas entering the air duct through the fire-fighting pipe and exiting through the gas outlet, thereby detecting blockages within the fire-fighting pipeline. In addition, by flaring the gas inlet of the connector relative to the gas outlet in the first direction, when the connector is connected to the sprinkler head of the fire pipe, the flared air duct ensures that the sprinkler head can be inserted into the air duct of the connector even if the position of the sprinkler head is slightly off. This ensures that the gas can be effectively captured and measured, thereby improving the fault tolerance of the connection between the fire pipeline detection device and the fire pipe sprinkler head.

[0058] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0059] The fire pipeline testing device 100 of this application can be applied to the fire pipeline testing system 200 for lithium battery charging and discharging equipment (e.g., Figure 7 As shown, the fire pipeline testing system 200 includes a mechanical unit 201 and a fire pipe 202. The fire pipe 202 is mounted on the mechanical unit 201. When the fire pipeline testing device 100 is pushed into the mechanical unit 201, the docking part 11 of the fire pipeline testing device 100 is configured to dock with the sprinkler head 202a of the fire pipe 202, so that the test piece 12 can detect the flow rate and / or velocity of the gas sprayed from the sprinkler head 202a of the fire pipe 202 when gas is introduced into the fire pipe 202.

[0060] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the fire pipeline testing device (partial structure omitted) disclosed in the embodiments of this application. Figure 2 yes Figure 1 A partial enlarged view at point A. The fire pipeline testing device 100 includes a connector 11 and a test piece 12. The connector 11 has an internal air duct 111. The air duct 111 has a gas inlet 111a and a gas outlet 111b that are opposite to and connected along a first direction X. The gas inlet 111a is flared relative to the gas outlet 111b along the first direction X; that is, the gas inlet is a flared end. The gas inlet 111a is configured to allow the sprinkler head 202a of the fire pipe 202 to extend into it, so that the sprinkler head 202a of the fire pipe 202 is located within the air duct 111. The test piece 12 is connected to the gas outlet 111b and is configured to detect the flow rate and / or velocity of the gas entering the air duct 111 through the fire pipe 202 and exiting through the gas outlet 111b.

[0061] First, in the fire pipeline detection device 100 disclosed in this application, when the gas inlet 111a is flared out relative to the gas outlet 111b along the first direction X, the opening area of ​​the gas inlet 111a is relatively large, which can more effectively collect the gas sprayed from the sprinkler head 202a and guide it smoothly into the air duct 111.

[0062] Secondly, the flared gas inlet 111a provides greater tolerance for the sprinkler head 202a. Even if the spray direction of the sprinkler head 202a is not perfectly aligned with the central axis of the gas inlet 111a, the gas sprayed from the fire pipe 202 sprinkler head 202a can still be collected by the gas inlet 111a and guided into the air duct 111. This reduces the requirements for the installation accuracy of the sprinkler head 202a and improves the fault tolerance of the connection between the fire pipeline detection device 100 and the fire pipe 202 sprinkler head 202a.

[0063] In addition, the flared gas inlet 111a can better accommodate different types of sprinkler heads 202a. Different models of sprinkler heads 202a may have different spray patterns and spray angles. This flared design of the gas inlet 111a can collect the gas sprayed by these sprinkler heads 202a more widely, thereby improving the versatility of the fire pipe detection device.

[0064] It is understood that the aforementioned docking member 11 may be a trumpet-shaped structure or a cylinder with a stepped sidewall along the first direction X. This application will describe the docking member 11 as a trumpet-shaped structure in the following description.

[0065] It is understood that the aforementioned test piece 12 can be a flow meter and / or an anemometer, etc. The flow meter can directly measure the flow rate at the gas outlet 111b, thereby intuitively reflecting whether there is a blockage in the fire pipe 202 through the magnitude change of the test result. For example, observe the test result of the flow meter within a preset time (e.g., 1 minute, 3 minutes, 5 minutes, etc.), and compare the test result of the flow meter with the normal flow rate measured in a normal, unblocked fire pipe 202. If the measured flow rate is lower than the normal flow rate, it indicates that there is a blockage in the fire pipe 202. If the measured flow rate is basically the same as the normal flow rate, it indicates that there is no blockage in the fire pipe 202. If an anemometer is used, the flow rate can be calculated using the formula (flow rate = wind speed × cross-sectional area) after the wind speed value is measured by the anemometer. If the flow rate value is basically the same as the normal flow rate value, it means that there is no blockage in the fire pipe 202. If the flow rate value is less than the normal flow rate value, it indicates that there is a blockage in the fire pipe 202.

[0066] In some embodiments, please refer to Figure 2 The fire pipeline inspection device 100 also includes a support member 2, and a connecting member 11 is rotatably mounted on the support member 2. The rotation direction of the connecting member 11 intersects with the first direction X. The installation position and direction of the fire pipe 202 sprinkler head 202a may vary depending on the building structure or design requirements. By rotatably connecting the connecting member 11 to the support member 2, and with the rotation direction of the connecting member 11 intersecting with the first direction X, it is ensured that the gas inlet 111a is accurately aligned with the sprinkler head 202a. This allows the fire pipeline inspection device 100 to adapt to various fire pipe 202 sprinkler heads 202a, thus improving the versatility of the fire pipeline inspection device 100.

[0067] Optionally, please refer to Figure 2 and Figure 3 , Figure 3This is a schematic diagram illustrating the specific structure of the connection between the support member and the docking member disclosed in this application. The support member 2 includes two spaced-apart support portions 21. Each support portion 21 has a first shaft connection portion 211. The docking member 11 has a second shaft connection portion 112 corresponding to the first shaft connection portion 211, and the second shaft connection portion 112 is disposed along the first direction X near the gas outlet 111b. The second shaft connection portion 112 is shafted to the first shaft connection portion 211, so that the docking member 11 can rotate relative to the support portion 21.

[0068] First, the support member 2 includes two spaced-apart support portions 21. These portions are connected by a first shaft connection 211 on the support portion 21 and a corresponding second shaft connection 112 on the docking member 11, allowing the docking member 11 to rotate relative to the support portion 21. The rotation direction of the support portion 21 intersects the gas flow direction (first direction X), enabling the docking member 11 to be adjusted in multiple directions on a plane perpendicular to the gas flow direction. This allows it to adapt to different installation positions of the spray heads 202a, ensuring that the gas from the spray heads 202a can accurately enter the air duct 111, thereby improving the detection efficiency of the fire pipeline detection device 100.

[0069] Secondly, through two spaced-apart support portions 21, the second shaft connection portion 112 is arranged close to the gas outlet 111b along the first direction X. The second shaft connection portion 112 is shafted to the first shaft connection portion 211 on the support portion 21. This structure can ensure the stability of the docking part 11 when adjusting the angle, thereby extending the service life of the fire pipeline detection device 100.

[0070] It is understood that the support member 2 can be a U-shaped bracket or a rectangular bracket, and the support part 21 can be a cylindrical support leg or a square column support leg. This embodiment does not make specific limitations on this.

[0071] It is understood that the first shaft connection 211 and the second shaft connection 112 can be either a shaft or a bearing, with the shaft installed inside the bearing to achieve shaft connection. Alternatively, either the first shaft connection 211 or the second shaft connection 112 can be a rotating shaft or a shaft hole; this embodiment does not specifically limit this.

[0072] It is understood that the docking part 11 and the sprinkler head 202a of the fire pipe 202 can be docked manually or through a drive mechanism. This application will use the docking part 11 and the sprinkler head 202a of the fire pipe 202 docking through a drive mechanism for the following explanation.

[0073] Optionally, the fire pipeline detection device 100 further includes a first drive mechanism (not shown in the figure), which is connected to the docking member 11. The first drive mechanism is configured to drive the docking member 11 to move along the first direction X to approach or move away from the sprinkler head 202a of the fire pipeline 202. The fire pipeline detection device 100 also includes a second drive mechanism (not shown in the figure), which is connected to the docking member 11. The second drive mechanism is configured to drive the docking member 11 to move along the second direction Z, so that the position of the docking member 11 relative to the sprinkler head 202a of the fire pipeline 202 along the second direction Z is adjustable. The second direction Z intersects the first direction X.

[0074] The first and second drive mechanisms drive the docking member 11 to move along the first direction X (gas flow direction) and the second direction Z (direction intersecting the first direction X), respectively. The coordinated operation of the two drive mechanisms allows the docking member 11 to automatically align with the spray head 202a. This reduces the risk of errors or malfunctions caused by improper manual operation, ensuring that the spray head 202a accurately extends into the gas inlet 111a. Furthermore, the first and second drive mechanisms enable rapid movement and adjustment of the docking member 11, making the fire pipe blockage detection process more efficient.

[0075] It is understood that the first drive mechanism and the second drive mechanism mentioned above can be the same or different. Specifically, they can be a lead screw-nut motor or a gear-rack motor. This embodiment does not make any specific limitations on this.

[0076] In some embodiments, please refer to Figure 2 The fire pipeline testing device 100 also includes a carrier 13, a docking part 11 and a test piece 12 are both disposed on the carrier 13, and a first drive mechanism is connected to the carrier 13. The first drive mechanism is configured to drive the carrier 13 to move along the first direction X, so as to drive the docking part 11 and the test piece 12 to move simultaneously along the first direction X.

[0077] The docking part 11 and the test piece 12 are mounted on the same carrier 13, and the carrier 13 is moved as a whole along the first direction X by the first drive mechanism. This synchronous movement of the docking part 11 and the test piece 12 ensures that when the docking part 11 is aligned with the sprinkler head 202a of the fire pipe 202, the test piece 12 is also in a suitable position relative to the gas outlet 111b, reducing the time required to adjust the position between the docking part 11 and the test piece 12, making the testing process more efficient.

[0078] It is understood that the aforementioned support member 13 may be a support plate or a support block, and this embodiment does not specifically limit it.

[0079] Please see Figure 4 , Figure 4 yes Figure 1 A magnified view of a portion at point B. The fire pipeline inspection device 100 also includes an adjustment component 5, which is configured to adjust the position of the support member 13 along the third direction Y.

[0080] By setting the adjustment component 5, which can adjust the position of the carrier 13 along the third direction Y, even if there is a certain distance error between the sprinkler head 202a on the fire pipe 202 and the docking part 11 along the third direction Y, the adjustment component 5 can automatically compensate for the distance error between the sprinkler head 202a and the docking part 11, thereby ensuring the precise alignment of the docking part 11 and the sprinkler head 202a.

[0081] In addition, the position of the carrier 13 along the third direction Y can be adjusted by adjusting component 5. In this way, when the docking component 11 and the sprinkler head 202a of the fire pipe 202 are docked, there is no need to make fine adjustments to the position of the docking component 11, which can save docking time and reduce the complexity of docking operation.

[0082] Optionally, the adjustment assembly 5 includes a fixed base 51 and an elastic member 52. The fixed base 51 is located on one side of the support member 13 along the third direction Y. The elastic member 52 is connected to the fixed base 51 and the support member 13 along the third direction Y. The support member 13 can squeeze the elastic member 52 along the third direction Y to adjust the position of the test unit 1 in the third direction Y.

[0083] By adjusting the assembly 5, which includes a fixed base 51 and an elastic element 52, the carrier 13 can press the elastic element 52 along the third direction (Y). This provides a stable fulcrum for the elastic element 52 through the fixed base 51, ensuring the reliability of the adjusting assembly 5. Furthermore, the buffering and reset function of the elastic element 52 allows the carrier 13 to move and reset along the third direction (Y). This enables the carrier 13 to return to its initial position after being subjected to external force, facilitating rapid docking of the next docking component with the next spray head 202a, achieving automation and continuity of the inspection process, and thus improving inspection efficiency.

[0084] It is understood that the aforementioned fixing base 51 can be a frame-type fixing base or a base plate-type fixing base, etc., and this embodiment does not specifically limit it.

[0085] It is understood that the elastic element 52 mentioned above can be a spring, a sheet, or elastic rubber, etc., and this embodiment does not specifically limit it.

[0086] It is understood that the aforementioned fixing seat 51 may be provided only on one side of the bearing member 13 along the third direction Y, or it may be provided on both sides. The corresponding elastic member 52 may be connected only on one side of the bearing member 13, or it may be connected on both sides. This embodiment does not make specific limitations on this.

[0087] Optionally, please refer to Figure 4 and Figure 5 , Figure 5 This is a schematic diagram of the specific structure of the fire pipeline testing device (including a waterproof cover and a cable chain) disclosed in this application embodiment. The aforementioned support member 13, docking member 11, and test member 12 constitute a test unit 1. To improve the docking efficiency of the fire pipeline testing device 100, the fire pipeline testing device 100 may include multiple test units 1, which are arranged at least at intervals along the third direction Y. Along the third direction Y, adjacent test units 1 are connected by a connector 3. A fixing base 51 is disposed on the connector 3, and the aforementioned first driving mechanism is connected to the connector 3. The first driving mechanism is configured to drive the connector 3 to move along the first direction X, so as to drive two adjacent test units 1 to move simultaneously along the first direction X to approach or move away from the sprinkler head 202a of the fire pipe 202. The third direction Y intersects with both the first direction X and the second direction Z.

[0088] The fire pipeline testing device 100 includes multiple test units 1, which are arranged at least at intervals along a third direction Y. Adjacent test units 1 are connected by connectors 3 along the third direction Y. A first drive mechanism drives the connectors 3 to move along a first direction X, thereby causing adjacent test units 1 to move simultaneously along the first direction X. Thus, when the first drive mechanism drives the connectors 3 to move along the first direction X, it can simultaneously move multiple test units 1 along the third direction Y towards or away from the sprinkler heads 202a of the fire pipeline 202. This allows the fire pipeline testing device 100 to simultaneously connect multiple sets of connectors 11 and sprinkler heads 202a in a single drive operation of the first drive mechanism, thereby improving the testing efficiency of the fire pipeline testing device 100.

[0089] It is understood that the aforementioned connector 3 can be a long strip plate or a long strip column, and this embodiment does not specifically limit it.

[0090] It is understood that the aforementioned connector 3 can be a complete long strip, with multiple test units 1 disposed on the same connector 3. Alternatively, the connector can also be multiple short strips, with each pair of adjacent test units 1 connected by a short strip. This application will describe the connector 3 as a single long strip, with multiple test units 1 disposed on the same connector 3, in the following description.

[0091] It is understandable that when the fire pipeline testing device 100 includes multiple test units 1, and the multiple test units 1 are arranged at least along the third direction Y, the above-mentioned adjustment component 5 can also adjust the spacing error between multiple sprinkler heads 202a along the third direction, thereby improving the docking efficiency between the fire pipeline testing device 100 and the fire pipe 202.

[0092] It is understood that there may be multiple adjustment components 5, and each adjustment component 5 may be respectively set on one side of each support member 13 along the third direction Y, or respectively set on both sides of each support member 13 along the third direction Y. This embodiment does not make specific limitations in this regard.

[0093] Optionally, the fire pipeline inspection device 100 also includes a guide mechanism 31, which is disposed on the connector 3 and extends along the third direction Y. The carrier 13 is slidably connected to the guide mechanism 31 along the third direction Y. The guide mechanism 31 is configured to guide the movement of the carrier 13 along the third direction Y.

[0094] By setting the guide mechanism 31, the movement of the carrier 13 in the third direction Y can be precisely guided, thereby ensuring that the carrier 13 moves along the predetermined track and avoiding movement errors caused by offset or shaking.

[0095] In addition, through the combined action of the guide mechanism 31 and the elastic element 52, it is possible to ensure that the position of the bearing element 13 is adjustable along the third direction Y, and also to ensure the accuracy of the movement direction of the bearing element 13.

[0096] It is understood that the aforementioned guide mechanism 31 may be a combination of a guide rail and a slider, or a combination of a ball screw and a slider, etc. This embodiment does not specifically limit this.

[0097] Optionally, the aforementioned support member 13, docking member 11, and test member 12 constitute a test unit 1, and the fire pipeline testing device 100 includes multiple test units. The fire pipeline testing device 100 also includes a lifting plate 4, and a second drive mechanism is disposed below the lifting plate 4 along the second direction Z. The second drive mechanism is connected to the lifting plate 4 and is configured to drive the lifting plate 4 to move along the second direction Z, thereby causing multiple test units 1 to move simultaneously along the second direction Z.

[0098] By having multiple test units 1 share a single second drive mechanism, the number of drive mechanisms can be reduced. This reduces the manufacturing cost of the fire pipeline testing device 100 and enables synchronous control of multiple test units 1, thereby improving the testing efficiency of the fire pipeline testing device 100.

[0099] It is understood that the aforementioned lifting plate 4 can be a metal plate or an engineering plastic plate, and this embodiment does not specifically limit it.

[0100] It is understood that multiple test units 1 on the lifting plate 4 can be respectively arranged on both sides of the lifting plate 4 along the first direction X, and multiple test units 1 located on the same side can be spaced apart along the third direction Y. At this time, the connecting parts 3 on both sides of the lifting plate 4 along the first direction X can be controlled by different first drive mechanisms, or they can be controlled by the same first drive mechanism. For example, two nuts can be connected by a screw, and the two nuts can be connected to the moving parts on both sides respectively. When the screw rotates, the two nuts will move in opposite directions along the axial direction of the screw, thereby driving the moving parts on both sides to move simultaneously along the first direction X towards the sprinkler head 202a of the fire pipe 202. This embodiment does not make specific limitations on this.

[0101] It is understandable that waterproof covers 41 can also be installed on both sides of the lifting plate 4 along the third direction (e.g. Figure 5 As shown, the power supply and wiring in the fire pipeline testing device 100 are enclosed within it to prevent damage to electrical components from residual water in the fire pipe 202 during testing. Additionally, a cable chain 42 (such as...) can be installed on the lifting plate 4. Figure 5 As shown, the power cord of test piece 12 is placed in the cable chain. When test piece 12 moves, the cable chain can move the power cord together, which can prevent the power cord from being damaged by dragging.

[0102] Optionally, please refer to Figure 5 and Figure 6 , Figure 6 This is a schematic diagram of the sensor structure disclosed in an embodiment of this application. The fire pipeline detection device 100 further includes a first sensor 6, which is disposed on the docking member 11 and configured to detect the movement position of the docking member 11 along a first direction X. A first drive mechanism is configured to start or stop driving the docking member 11 to move along the first direction X based on the movement position of the docking member 11 along the first direction X. The fire pipeline detection device 100 also includes a second sensor 7, which is disposed on the docking member 11 and configured to detect the movement position of the docking member 11 along a second direction Z. The second drive mechanism is configured to start or stop driving the docking member 11 to move along the second direction Z based on the movement position of the docking member 11 along the second direction Z.

[0103] First, by setting the first sensor 6 and the second sensor 7 to monitor the position of the docking part 11 in the first direction X and the second direction Z in real time, the docking part 11 can be made to move closer to or further away from the sprinkler head 202a, thereby improving the docking accuracy between the fire pipeline detection device 100 and the fire pipeline 202 sprinkler head 202a.

[0104] Secondly, through the linkage between the sensor and the drive mechanism, the drive mechanism can automatically adjust the position of the docking part 11 based on the real-time position feedback. This avoids detection errors or failures caused by positional deviations, thereby enhancing the detection reliability of the fire pipeline detection device 100.

[0105] In addition, the first sensor 6 and the second sensor 7 can monitor the position of the docking part 11 in real time, which can help the docking part 11 to quickly and accurately locate the target position, thereby reducing the time required for docking part 11 and fire pipe 202 sprinkler head 202a to dock.

[0106] It is understood that the first sensor 6 and the second sensor 7 mentioned above can be photoelectric sensors or proximity switches, etc., and this embodiment does not specifically limit them.

[0107] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of the fire-fighting pipeline testing system for lithium battery charging and discharging equipment disclosed in this application. Secondly, this application also discloses a fire-fighting pipeline testing system 200 for lithium battery charging and discharging equipment, including a mechanical unit 201, a fire-fighting pipe 202, and a fire-fighting pipeline testing device 100 as described in the first aspect. The fire-fighting pipe 202 is disposed on the mechanical unit 201. When the fire-fighting pipeline testing device 100 is pushed into the mechanical unit 201, the docking part 11 of the fire-fighting pipeline testing device 100 is configured to dock with the sprinkler head 202a of the fire-fighting pipe 202, so that the test piece 12 can detect the flow rate and / or velocity of the gas ejected from the sprinkler head 202a of the fire-fighting pipe 202 when gas is introduced into the fire-fighting pipe 202.

[0108] When the fire pipeline detection device 100 is pushed into the mechanical unit 201, the docking part 11 of the fire pipeline detection device 100 can dock with the sprinkler head 202a of the fire pipeline 202. This allows the flow rate and / or velocity of the gas sprayed from the sprinkler head 202a of the fire pipeline 202 to be detected when gas is introduced into the fire pipeline 202. In this way, the fire pipeline detection device 100 can detect the blockage in the fire pipeline 202 to confirm whether the fire pipeline 202 can be used normally. If a blockage occurs, it can be repaired in time to ensure fire safety.

[0109] It is understood that the fire-fighting pipe testing device 100 of this application can test the fire-fighting pipe 202 inside the lithium battery formation and capacity testing equipment. Specifically, the formation and capacity testing equipment usually includes multiple storage locations, and the mechanical unit 201 is installed in one of these locations. When the lithium battery is being formed and capacity tested, the lithium battery is placed inside the mechanical unit 201, and the sprinkler head 202a of the fire-fighting pipe 202 on the mechanical unit 201 is aimed at the inside of the mechanical unit 201, so as to extinguish the fire in time if the lithium battery catches fire. However, when it is necessary to test the blockage of the fire-fighting pipe 202 on the mechanical unit 201, the lithium battery is not placed inside the mechanical unit 201. Instead, the fire-fighting pipe testing device 100 of the first aspect of this application is pushed into the mechanical unit 201, and the connecting part 11 is used to connect with the sprinkler head 202a of the fire-fighting pipe 202, so as to test the blockage of the fire-fighting pipe 202 through the test piece 12.

[0110] It is understood that the mechanical unit 201 may be a stainless steel frame or a fire-resistant frame made of glass fiber reinforced material and inorganic adhesive, etc. This embodiment does not make specific limitations on this.

[0111] In this embodiment, the fire pipeline testing device 100 may have the same structure as any of the fire pipeline testing devices 100 in the above embodiments and may bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0112] The following is a brief description of the usage process of the fire pipeline testing device 100 of this application:

[0113] The fire pipeline testing device 100 is pushed into the mechanical unit 201. The second drive mechanism drives all the test units 1 to move along the third direction Y to a height approximately the same as the sprinkler head 202a of the fire pipe 202. Then, the first drive mechanism drives the docking parts 11 of all the test units 1 to move along the first direction X to get closer to the sprinkler head 202a of the fire pipe 202. During this process, the docking parts 11 can be rotated and adjusted according to the specific direction of the fire pipe 202. The spacing error between the multiple fire pipe 202 sprinkler heads 202a is adjusted by the adjustment component 5. The first sensor 6 and the second sensor 7 detect the position of the docking parts 11 in real time and control the first drive mechanism and the second drive mechanism to adjust respectively. Finally, the sprinkler heads 202a of each fire pipe 202 are at least partially inserted into the air duct 111, which means that the docking parts 11 and the sprinkler heads 202a are successfully docked. Gas is introduced into the fire hydrant pipe 202. The flow rate and / or velocity of the gas discharged from the gas outlet 111b of the connector 11 are read through the test piece 12. If the measured gas flow rate and / or velocity are basically the same as those measured in a normal, unblocked fire hydrant pipe within a certain period of time, it indicates that the fire hydrant pipe 202 is unblocked and can be used normally. If, during the test, the measured gas flow rate and / or velocity are found to be lower than those measured in a normal, unblocked fire hydrant pipe 202, it indicates that there is a blockage in the fire hydrant pipe 202, and it needs to be cleared.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
