Technical Field

[0001] The utility model relates to the technical field of battery energy storage, in particular to a water sprinkler fire extinguishing nozzle and an industrial and commercial energy storage cabinet thereof. Background Art

[0002] Battery energy storage can promote the integration of new energy sources, improve power system flexibility, and support the safe and stable operation of new power systems. It has become a key technology for building power systems. However, with the rapid development of the energy storage industry, the pressure on safe construction and operation of energy storage is also increasing. At the same time, energy storage safety issues have become a bottleneck restricting the further development of the lithium-ion battery energy storage industry. For industrial and commercial energy storage, the large capacity of energy storage systems, once thermal runaway occurs, will continue chemical reactions, continuously release heat, and easily reignite and cause explosion risks.

[0003] In water fire fighting systems, wet water sprinkler fire extinguishing technology is currently mostly used. When a fire occurs and reaches a certain temperature, the sprinkler head will automatically open and water will extinguish the fire through the sprinkler head splash plate.

[0004] However, after installation, traditional fire sprinklers spray water in an umbrella-shaped pattern, with blind spots below the sprinklers. Therefore, multiple sprinklers are required to achieve full water coverage. Traditional fire sprinkler installation requires the installation of fire piping for each sprinkler. Therefore, when using traditional fire sprinklers in commercial and industrial energy storage cabinets, achieving full water coverage also complicates the installation of fire piping. Utility Model Content

[0005] The purpose of the present utility model is to provide a water sprinkler fire extinguishing nozzle, by installing an inclined fire sprinkler below a rotary joint unit, and installing a rod body and water wheel blades inside the rotary joint unit. After the fire sprinkler is started, water flows through the rotary joint unit and can drive the fire sprinkler to rotate through the water wheel blades. In this way, a fire sprinkler can achieve a larger water spray coverage range, thereby reducing the length of the fire pipeline installation and reducing the complexity of the fire pipeline installation.

[0006] To achieve the above-mentioned object, the present invention provides a water sprinkler fire extinguishing nozzle, comprising a rotary joint unit, wherein one end of the rotary joint unit is provided with a connecting pipe head, and the other end of the rotary joint unit is provided with at least one mounting pipe head, on which a fire sprinkler is mounted, wherein the central axis of the mounting pipe head forms an angle with the central axis of the rotary joint unit;

[0007] A rod body and a water wheel blade mounted on the rod body are also installed in the rotary joint unit, and the rod body is connected and fixed to the mounting pipe head.

[0008] The lower end of the rod body is provided with a threaded hole, and the screw is inserted into the position between the plurality of mounting pipe heads and then screwed and fixed with the threaded hole on the rod body.

[0009] The rotary joint unit includes an outer cylinder, an inner cylinder and a rotary sealing structure. The inner cylinder is installed inside the outer cylinder through the rotary sealing structure. The connecting pipe head is located at the upper end of the outer cylinder and the installation pipe head is located at the lower end of the inner cylinder.

[0010] The rotary sealing structure includes a bearing, a sealing ring and a second spacer ring. The bearing, the sealing ring and the second spacer ring are installed between the inner cylinder and the outer cylinder, and the second spacer ring is located between the bearing and the sealing ring. The bearing is positioned by a retaining spring.

[0011] There are two bearings, and a first spacer ring is installed between the two bearings.

[0012] There are two mounting tube heads, and the two mounting tube heads are symmetrically arranged around the central axis of the rotary joint unit.

[0013] An industrial and commercial energy storage cabinet comprises an energy storage cabinet body, a fire extinguishing pipeline is installed inside the energy storage cabinet body, and a water sprinkler fire extinguishing nozzle is installed on a pipe joint of the fire extinguishing pipeline.

[0014] Compared with the prior art, the present invention has the following technical effects:

[0015] 1. The utility model installs an inclined fire sprinkler head below the rotary joint unit, and installs a rod body and water wheel blades inside the rotary joint unit.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] Example 1:

[0029] See Figure 1 、 2 A water sprinkler fire extinguishing nozzle includes a rotary joint unit, one end of the rotary joint unit is provided with a connecting pipe head 11, the other end of the rotary joint unit is provided with a mounting pipe head 31, a fire sprinkler head 40 is mounted on the mounting pipe head 31, and the central axis of the mounting pipe head 31 and the central axis of the rotary joint unit form an angle a; a rod body 32 and a water wheel blade 33 mounted on the rod body 32 are also installed in the rotary joint unit, and the rod body 32 is fixedly connected to the mounting pipe head 31.

[0030] By installing an inclined fire sprinkler 40 below the rotary joint unit and installing a rod body 32 and a water wheel blade 33 inside the rotary joint unit, after the fire sprinkler 40 is started, water flows through the rotary joint unit and can drive the fire sprinkler 40 to rotate through the water wheel blade 33. In this way, the fire sprinkler can achieve a larger water spray coverage range, thereby reducing the length of the fire pipeline installation and reducing the complexity of the fire pipeline installation.

[0031] The water wheel blades 33 are of the prior art, for example, a structure similar to a fan blade, or a spiral blade structure disclosed in CN118602846A.

[0032] The angle a is an acute angle or an obtuse angle. In this embodiment, preferably, the angle a is between 30° and 50°.

[0033] Furthermore, in order to facilitate the installation of the rod body 32 , a threaded hole is provided at the lower end of the rod body 32 , and the screw 34 is inserted into the area between the plurality of mounting tube heads 31 and is screwed and fixed to the threaded hole on the rod body 32 .

[0034] In this embodiment, the rotary joint unit includes an outer cylinder 10, an inner cylinder 30, and a rotary seal structure 20. The inner cylinder 30 is mounted inside the outer cylinder 10 via the rotary seal structure 20. The connecting pipe head 11 is located at the upper end of the outer cylinder 10, and the mounting pipe head 31 is located at the lower end of the inner cylinder 30. The outer cylinder 10 is screwed and fixed to the pipe joint 50 via the connecting pipe head 11. The water wheel blades 33 are located inside the inner cylinder 30. The inner cylinder 30 can rotate under the drive of the water wheel blades 33. The mounting pipe head 31 has an internal thread, and the fire sprinkler head 40 is screwed and fixed to the mounting pipe head 31. The provision of the rotary seal structure 20 enables both the rotation of the inner cylinder 30 and the sealing between the outer cylinder 10 and the inner cylinder 30.

[0035] In this embodiment, see Figure 1 The rotating sealing structure 20 includes a bearing 21, a sealing ring 22 and a second spacer ring 24. The bearing 21, the sealing ring 22 and the second spacer ring 24 are installed between the inner cylinder 30 and the outer cylinder 10, and the second spacer ring 24 is located between the bearing 21 and the sealing ring 22. The outer ring and the inner ring of the bearing 21 are interference fit with the outer cylinder 10 and the inner cylinder 30 respectively, and the bearing 21 is positioned by a retaining ring 25.

[0036] Furthermore, two bearings 21 are provided, and a first spacer ring 23 is installed between the two bearings 21 .

[0037] Of course, in addition to adopting the above structure, the rotary joint unit can also adopt a rotary sealing device with high pressure resistance and high speed resistance disclosed in CN115126785B. When applied to this application, the rotating shaft is connected and fixed to the pipe joint 50, and multiple mounting pipe heads 31 are arranged at the bottom of the shell 1, the rod body 32 is in the shell 1 and is connected and fixed to the shell 1, and the water wheel blades 33 are located in the cavity of the rotating shaft.

[0038] Example 2:

[0039] In this embodiment, see Figure 1 、 2Two mounting pipe heads 31 are provided, evenly spaced about the central axis of the rotary joint unit. The rod body 32 is fixedly connected to the portion between the two mounting pipe heads 31. This structure allows two fire sprinkler heads 40 to be installed on a single fire sprinkler head, improving the balance of the fire sprinkler head during rotation, enhancing its stability, and increasing the amount of water sprayed during fire extinguishing.

[0040] Of course, three mounting pipe heads 31 can also be provided as needed. Similarly, the three mounting pipe heads 31 are evenly distributed in a ring around the central axis of the rotary joint unit.

[0041] Example 3:

[0042] See also Figure 3 An industrial and commercial energy storage cabinet includes an energy storage cabinet body 70, a fire extinguishing pipeline 60 is installed inside the energy storage cabinet body 70, and a water sprinkler fire extinguishing nozzle is installed on the pipe joint 50 of the fire extinguishing pipeline 60.

[0043] The working principle or action process of the utility model is as follows:

[0044] Pressurized firefighting water flows through the fire-extinguishing pipeline 60. Before a fire breaks out, the glass bulb on the fire sprinkler head 40 seals the nozzle head 40, preventing the water from spraying. When a fire breaks out in the energy storage cabinet body 70, the flames and heat cause the glass bulb on the fire sprinkler head 40 to condense, causing the nozzle head 40 to begin spraying water. As the water flows through the inner cylinder 30, the water impeller blades 33, which extend into the inner cylinder 30, drive the fire sprinkler head 40 to rotate. This allows the fire sprinkler head to achieve a wider water spray coverage area, thereby reducing the length and complexity of the firefighting pipeline installation.
