Battery test box spraying device

Abstract

This utility model relates to the field of battery testing box technology, and specifically discloses a battery testing box sprinkler device. A water supply pipe and three three-way sprinkler heads are installed inside the battery testing box. Spraying for fire extinguishing can be triggered inside the box by manually controlling the solenoid valve. The fire-fighting water solenoid valve controlling the spray is located at the top of the box, effectively avoiding the influence of the box's high temperature. The lower opening of the sprinkler head is fan-shaped, which increases the water output range and forms a multi-angle, wide-range spray area, bypassing obstructions such as battery modules, metal supports, and multi-layer partitions. The fan-shaped opening also allows for the spraying of more fire-fighting water per unit time. Three sets of three-way sprinkler heads are evenly distributed within the test space inside the box, and the water flow diffuses, covering the fire point. This can reduce battery temperature and extinguish the fire source in a short time, and can cover the entire test space when the sprinkler heads are activated.

Description

Technical Field

[0001] This utility model relates to the field of battery testing box technology, and in particular to a battery testing box spray device. Background Technology

[0002] The spray system in battery testing chambers plays a crucial role in battery testing, primarily used within the testing chamber itself. It provides a stable environment for simulating various environmental conditions to test battery performance, and also ensures testing safety by extinguishing fires during high-temperature testing that could lead to ignition. Widely used in battery research and development, quality inspection, and other scenarios, it accurately simulates high and low temperatures, humidity, and special gas environments to obtain battery performance data, while simultaneously preventing fires in emergencies.

[0003] Currently, various equipment and methods are used to achieve environmental simulation and sprinkler fire suppression functions for battery testing chambers. For sprinkler fire suppression, commonly used fire sprinklers with a large quantity and low cost are usually selected. The fire sprinklers produced and used in daily fire protection work are all fire sprinklers with a straight spray path. The application scenarios of traditional sprinklers are mostly open spaces without dense obstructions (such as ceiling sprinklers in ordinary buildings, surface cooling of small equipment, etc.). Straight spray can achieve "point-to-point" or "area coverage" in the most direct way. By concentrating the water flow to form a certain range, when there are no obstacles, the straight water flow can naturally diffuse with the help of gravity to cover the plane area below (such as the ground, the top of the equipment), meeting the basic fire suppression or cooling needs.

[0004] However, the above method has a prominent problem: in special scenarios such as battery test chambers where there are dense obstructions such as battery modules, metal brackets, and multiple partitions, the limitations of traditional straight-jet fire sprinklers become apparent. Obstructions will cut off the straight water flow path, resulting in coverage blind spots. The fire in the blind spot cannot come into contact with the spray water, which means that the initial fire cannot be quickly suppressed. The fire may spread outward from the blind spot, thus prolonging the time required to extinguish the fire and increasing the damage to the test chamber. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a battery test chamber spray device. It solves the problem that in special scenarios such as battery test chambers where there are dense obstructions such as battery modules, metal brackets, and multiple partitions, the limitations of traditional straight-jet fire sprinklers become apparent. Obstructions can cut off the straight water flow path, resulting in blind spots. The fire in these blind spots cannot reach the spray water flow, making it impossible to quickly suppress the initial fire. The fire may spread outward from the blind spots, thus prolonging the time required to extinguish the fire and increasing the damage to the test chamber.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A battery test chamber spray device includes a battery test chamber body. A support mechanism for installing spray pipes is provided on the surface of the battery test chamber body. The support mechanism includes a set of L-shaped mounting bases, a set of arc-shaped opening positioning plates, and two sets of cylindrical through holes. The L-shaped mounting bases are all fixedly connected to the surface of the battery test chamber body. The arc-shaped opening positioning plates are respectively located on the outer surface of the L-shaped mounting bases. The two sets of cylindrical through holes are respectively opened inside the L-shaped mounting bases and the arc-shaped opening positioning plates. A water supply pipe is provided on the outer surface of the L-shaped mounting bases and the arc-shaped opening positioning plates. A fire-extinguishing spray nozzle mechanism is provided on the outer surface of the water supply pipe. The nozzle mechanism includes an internal threaded connector, a fire-fighting solenoid valve, and three three-way spray heads. The internal threaded connector is located inside the water supply pipe. The fire-fighting solenoid valve is located on the outer surface of the water supply pipe. The three three-way spray heads are all located on the outer surface of the water supply pipe. When the spray heads are activated, they can cover the entire test space, effectively cooling and extinguishing the battery fire.

[0007] Preferably, a water pipe mounting plate is fixedly connected to the outer surface of the water pipe.

[0008] Preferably, an audible and visual alarm is fixedly connected to the upper end of the battery test box body, and a control panel is fixedly connected to one end of the battery test box body. When the internal temperature, humidity, etc. of the battery test box body exceed the preset values, the monitoring sensor installed inside the battery test box body will send an electrical signal to the audible and visual alarm, which will then issue an alarm to remind the staff of the current abnormality of the device.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The battery testing chamber is equipped with a water supply pipe and three three-way sprinkler heads. Fire suppression spraying can be triggered inside the chamber by manually controlling the solenoid valve. The fire-fighting water solenoid valve, located at the top of the chamber, effectively avoids the influence of the chamber's high temperature. The lower opening of the sprinkler head is fan-shaped, increasing the water output range and creating a multi-angle, wide-area spray zone. This bypasses obstructions such as battery modules, metal supports, and multiple partitions, and the fan-shaped opening sprays more fire-fighting water per unit time. Three sets of three-way sprinkler heads are evenly distributed within the test space inside the chamber, with the water flow spreading to cover the fire point. This quickly reduces battery temperature, extinguishes the fire, and prevents the fire from spreading from localized blind spots. When the sprinkler heads are activated, they cover the entire test space, effectively cooling and extinguishing the battery fire. Attached Figure Description

[0013] The battery test chamber sprinkler system of this application addresses the problem that traditional linear spray fire sprinklers have blind spots in battery test chambers with dense obstructions such as battery modules and metal brackets, leading to difficulties in suppressing fires, fire spread, and increased fire extinguishing difficulty. This is achieved by installing a water supply pipe and three three-way sprinkler heads inside the chamber, with a manually controlled solenoid valve to trigger the spray. The fire water solenoid valve is located at the top of the chamber to avoid the influence of high temperatures. The upper end of the water supply pipe has an internal threaded connector for connecting to the external water inlet pipe. The fan-shaped opening increases the water output range, forming a multi-angle, wide-range spray area that bypasses obstructions such as battery modules, metal brackets, and multiple partitions. Furthermore, the fan-shaped opening sprays more fire water per unit time. The three sets of three-way sprinkler heads are evenly distributed inside the chamber, covering the entire test space when activated, effectively cooling and extinguishing the battery fire. Example

[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the limitations of traditional straight-jet fire sprinklers in special scenarios such as battery test boxes where there are dense obstructions such as battery modules, metal brackets, and multiple partitions. Obstructions can cut off the straight water flow path, resulting in blind spots. The burning battery in the blind spot cannot come into contact with the spray water flow, causing the initial fire to be unable to be quickly suppressed. The fire may spread outward from the blind spot, thus prolonging the time required for fire extinguishing and increasing the damage to the test box. The overall idea is as follows: The battery test box sprinkler device includes a battery test box body 1. The surface of the battery test box body 1 is provided with a support mechanism for installing the sprinkler pipe. The support mechanism includes a set of L-shaped mounting pipe seats 2, a set of arc-shaped opening positioning plates 3, and two sets of cylindrical through holes 4. The set of L-shaped mounting pipe seats 2 are all fixedly connected to the battery test box body 1. On the surface, a set of arc-shaped opening positioning plates 3 are respectively set on the outer surface of a set of L-shaped mounting pipe seats 2. Two sets of cylindrical through holes 4 are respectively opened inside the set of L-shaped mounting pipe seats 2 and the set of arc-shaped opening positioning plates 3. A water supply pipe 5 is set on the outer surface of the set of L-shaped mounting pipe seats 2 and the set of arc-shaped opening positioning plates 3. The water supply pipe 5 is fixed by using L-shaped mounting pipe seats 2 and arc-shaped opening positioning plates 3. Both L-shaped mounting pipe seats 2 and arc-shaped opening positioning plates 3 are open. The water supply pipe 5 is first placed on the inner surface of the fixed L-shaped mounting pipe seat 2. At this time, the arc-shaped opening positioning plates 3 are placed on the surface of the water supply pipe 5, and the cylindrical through holes 4 opened inside the L-shaped mounting pipe seat 2 and the arc-shaped opening positioning plates 3 are aligned. At this time, it is fixed by screwing bolts and nuts inside the two sets of cylindrical through holes 4. The pipeline can be installed inside the box after it is prepared, avoiding the problem of water leakage at the joint.

[0015] A fire-extinguishing sprinkler mechanism is installed on the outer surface of the water supply pipe 5. The sprinkler mechanism includes an internal threaded connector 7, a fire water solenoid valve 8, and three three-way sprinkler heads 9. The internal threaded connector 7 is located inside the water supply pipe 5. The fire water solenoid valve 8 is located on the outer surface of the water supply pipe 5. All three three-way sprinkler heads 9 are located on the outer surface of the water supply pipe 5 and inside the battery test chamber body 1. A water pipe mounting plate 6 is fixedly connected to the outer surface of the water supply pipe 5 and is located at the upper end of the battery test chamber body 1. To prevent the battery from igniting during high-temperature battery testing, a fire-extinguishing sprinkler mechanism is installed inside the battery test chamber body 1. The unit is equipped with a water supply pipe 5 and three three-way sprinkler heads 9. It can be manually controlled to trigger the sprinkler fire extinguishing inside the box. The fire water solenoid valve 8 that controls the sprinkler is located at the top of the box, which can effectively avoid the influence of the high temperature of the box. An internal threaded connector 7 is opened at the top of the water supply pipe 5. The pipe connector is screwed on by the internal thread to connect to the external sprinkler water inlet pipe. Three sets of three-way sprinkler heads 9 are evenly distributed in the test space inside the box. When turned on, they can cover the entire test space and effectively cool down and extinguish the fire of the battery. The three-way sprinkler heads 9 adopt a fan-shaped opening to increase the amount and range of water sprayed per unit time.

[0016] An audible and visual alarm 11 is fixedly connected to the upper end of the battery test chamber body 1, and a control panel 12 is fixedly connected to one end of the battery test chamber body 1. The battery test chamber body 1 is used to simulate different environmental conditions to perform performance tests on batteries. During operation, the internal temperature is regulated by a temperature control system. Heating wires and cooling devices can make the internal temperature vary within a set range to test the battery's performance in high and low temperature environments. The humidity control system uses a humidifier and dehumidifier to regulate humidity, simulating humid or dry environments to examine the battery's tolerance to humidity. The gas conditioning system can fill with different gases to create a special gas atmosphere and evaluate the battery's performance in a specific gas environment. At the same time, sensors equipped inside the chamber monitor the temperature and humidity in real time. The system monitors parameters such as gas concentration and feeds the data back to the control panel 12. The control panel 12 precisely adjusts each environmental parameter according to preset values ​​to ensure a stable testing environment. This allows for accurate acquisition of battery performance data under different environmental conditions, providing a basis for battery research and development, quality testing, and more. Simultaneously, the control panel 12 can control the overall start and stop of the battery test chamber 1 by pressing the start / stop button. When the device simulates different environmental conditions, if the internal temperature or humidity of the battery test chamber 1 exceeds preset values, the monitoring sensors installed inside the battery test chamber 1 will send an electrical signal to the audible and visual alarm 11, which will then issue an alarm to alert staff to the abnormality of the device.

[0017] To address the problems existing in the prior art, this utility model provides a battery testing chamber spray device. Inside the battery testing chamber body 1, a water supply pipe 5 and three three-way spray heads 9 are installed. Spraying for fire extinguishing can be triggered inside the chamber by manually controlling the solenoid valve 8. The fire-fighting water solenoid valve 8, controlling the spray, is located at the top of the chamber, effectively avoiding the influence of the chamber's high temperature. The lower opening of the spray head 9 is fan-shaped, which increases the water output range, forming a multi-angle, wide-range spray area that can bypass obstructions such as battery modules, metal supports, and multi-layer partitions. Furthermore, the fan-shaped opening sprays more fire-fighting water per unit time. Three sets of three-way spray heads 9 are evenly distributed within the test space inside the chamber, and the water flow diffuses, covering the fire point. This can quickly reduce battery temperature, extinguish the fire source, and prevent the fire from spreading from local blind spots. When activated, it can cover the entire test space, effectively cooling and extinguishing the battery fire.

[0018] Working principle: The first step involves the battery test chamber body 1, which simulates different environmental conditions to test battery performance. During operation, the internal temperature is regulated by a temperature control system. Heating wires and a cooling device allow the internal temperature to fluctuate within a set range to test battery performance under high and low temperature environments. The humidity control system uses a humidifier and dehumidifier to regulate humidity, simulating humid or dry environments to examine the battery's tolerance to humidity. The gas regulation system can fill with different gases to create a special gaseous atmosphere, evaluating the battery's performance in specific gaseous environments. Simultaneously, sensors inside the chamber monitor parameters such as temperature, humidity, and gas concentration in real time and feed the data back to the control panel 1. 2. The control panel 12 precisely adjusts various environmental parameters according to preset values ​​to ensure a stable testing environment, so as to accurately obtain battery performance data under different environmental conditions and provide a basis for battery research and development, quality testing, etc. At the same time, the start and stop of the battery test chamber 1 can be controlled by pressing the start and stop button included in the control panel 12. When the device simulates different environmental conditions, when the internal temperature and humidity of the battery test chamber 1 exceed the preset values, the monitoring sensor installed inside the battery test chamber 1 will send an electrical signal to the audible and visual alarm 11, which will then issue an alarm to remind the staff of the current abnormality of the device.

[0019] In the second step, to prevent battery fire during high-temperature testing, a water supply pipe 5 and three three-way sprinkler heads 9 are installed inside the battery test chamber body 1. These can be manually activated to extinguish the fire. The fire-fighting water solenoid valve 8, controlling the sprinkler system, is located at the top of the chamber, effectively avoiding the influence of the chamber's high temperature. An internally threaded connector 7 is provided at the top of the water supply pipe 5, allowing for the installation of the pipe fitting via internal thread, connecting to the external sprinkler water inlet pipe. Three sets of three-way sprinkler heads 9 are evenly distributed within the test space inside the chamber, covering the entire test space when activated, effectively cooling and extinguishing the battery fire. The three-way sprinkler heads 9 have a fan-shaped opening. To increase the water spray volume and range per unit time, the water supply pipe 5 is fixed using an L-shaped mounting base 2 and an arc-shaped opening positioning piece 3. Both the L-shaped mounting base 2 and the arc-shaped opening positioning piece 3 are open. The water supply pipe 5 is first placed on the inner surface of the fixed L-shaped mounting base 2 (the L-shaped mounting base 2 is fixed by screwing). Then, the arc-shaped opening positioning piece 3 is placed on the surface of the water supply pipe 5, and the cylindrical through holes 4 inside the L-shaped mounting base 2 and the arc-shaped opening positioning piece 3 are aligned. The pipe is then fixed by screwing bolts and nuts into the two sets of cylindrical through holes 4. This method allows the pipe to be installed inside the box after the pipeline is in place, avoiding the problem of water leakage at the joints.

[0020] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
