Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher testing technology, specifically a fire extinguisher spray testing device. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are common fire-fighting equipment, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components and are designed for different types of fires. The spray performance of a fire extinguisher directly affects its fire-fighting effectiveness; therefore, fire extinguishers usually undergo a spray test before being put into use.

[0003] Currently, fire extinguisher spray performance testing usually relies on manual operation. Different groups of fire extinguishers may have different testing conditions, leading to errors in the test structure. There is a lack of accurate measurement of key parameters such as spray pressure, spray time, and spray distance. Furthermore, the test can only be conducted on fire extinguishers of a single size, resulting in poor applicability of the test device. Therefore, we need to propose a fire extinguisher spray testing device. Utility Model Content

[0004] The purpose of this invention is to provide a fire extinguisher spray testing device. By placing the fire extinguisher inside a fixed groove, clamping fire extinguishers of different sizes with a clamping assembly, and then moving the fire extinguisher to the height of the spray pipe with a hydraulic push rod, the device measures the spray pressure, spray time, and spray distance of the fire extinguisher using a scale, pressure detector, and timer during the spray test, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguisher spray test device, comprising a mounting plate, a fixing plate, and a test plate fixedly connected to the mounting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a fire extinguisher spray testing device, such as... Figure 1-4 As shown, the device includes a mounting plate 1, a fixing plate 2, and a test plate 5 fixedly connected to the mounting plate 1. The fixing plate 2 is mounted on the upper surface of the mounting plate 1 via a hydraulic push rod 11. The upper surface of the test plate 5 is provided with a spray pipe 4 and a scale 6, and a pressure detection module for detecting pressure is also provided on the upper surface of the test plate 5. The pressure detection module includes a pressure detector 7 and a pressure detection head 12. The pressure detector 7 is fixedly mounted on the upper surface of the test plate 5, and the pressure detection head 12 is connected to the pressure detector 7 and is located inside the spray pipe 4. By connecting the spray pipe 4 to the fire extinguisher, after the fire extinguisher is activated, the pressure of the fire extinguisher spray is detected by the pressure detection head 12 inside the spray pipe 4 and transmitted to the pressure detector 7 for display. The liquid sprayed by the fire extinguisher through the spray pipe 4 is also displayed on the upper surface of the test plate 5. The spray distance of the fire extinguisher is then confirmed by the scale 6.

[0024] Preferably, the upper surface of the fixing plate 2 is provided with a clamping assembly for clamping fire extinguishers of different sizes. The clamping assembly includes clamping plates 18 and auxiliary modules. The upper surface of the fixing plate 2 is provided with a fixing groove 14. Several sets of clamping plates 18 are provided, and the sets of clamping plates 18 are slidably disposed inside the fixing groove 14. Each set of clamping plates 18 is fixedly connected to a lower compression spring 19 on the side near the fixing plate 2. Several sets of limiting posts 17 corresponding to the lower compression spring 19 are provided inside the fixing groove 14, and the lower compression spring 19 is sleeved on the outer arc surface of the corresponding limiting post 17. The limiting posts 17 limit the lower compression spring 19 to prevent the lower compression spring 19 from bending and breaking after compression. Fire extinguishers of different sizes are placed inside the fixing groove 14 and between the sets of clamping plates 18. Then, the sets of clamping plates 18 clamp the fire extinguishers of different sizes under the action of the lower compression spring 19, which facilitates testing.

[0025] Furthermore, anti-slip rubber stickers are adhered to the corresponding surfaces of several sets of clamping plates 18, and movable blocks 16 are fixedly installed on the lower surfaces of several sets of clamping plates 18. The fixed grooves 14 are provided with movable grooves 15 corresponding to the movable blocks 16. The anti-slip rubber stickers on the sides of several sets of clamping plates 18 further enhance the stability of the clamping plates 18 in clamping the fire extinguisher. The movable blocks 16 are convex blocks and are inserted into the movable grooves 15 to ensure the stability of the clamping plates 18 during movement.

[0026] Furthermore, the auxiliary module includes a support ring 3, an upper compression spring 20, and an auxiliary clamping plate 21. The support ring 3 is fixedly mounted on the upper surface of the fixed plate 2. Several sets of upper compression springs 20 and auxiliary clamping plates 21 are provided. Several sets of upper compression springs 20 are fixedly mounted on the inner wall of the support ring 3, and several sets of auxiliary clamping plates 21 are fixedly mounted at the end of the upper compression spring 20 away from the support ring 3. The support ring 3 supports the upper compression spring 20. The upper half of the fire extinguisher contacts several sets of auxiliary clamping plates 21, and the upper compression spring 20 abuts against the auxiliary clamping plates 21 to clamp the upper half of the fire extinguisher, thereby further improving the stability of the fire extinguisher clamping and avoiding errors caused by personnel holding the test.

[0027] It is worth noting that several sets of side plates 8 are fixedly installed on the upper surface of the fixed plate 2. Two sets of telescopic rods 9 are fixedly installed on the corresponding surfaces of the several sets of side plates 8. One end of the two sets of telescopic rods 9 is fixedly connected to the corresponding auxiliary clamping plate 21, and the telescopic rods 9 do not contact the support ring 3. The telescopic rods 9 are supported by the side plates 8, and the two sets of telescopic rods 9 support one set of auxiliary clamping plates 21. When the auxiliary clamping plate 21 moves, the telescopic rods 9 extend and retract accordingly. At the same time, the telescopic rods 9 limit the movement of the auxiliary clamping plate 21, ensuring that the auxiliary clamping plate 21 moves in a straight line.

[0028] Specifically, the upper surface of the test plate 5 is provided with several sets of limiting rings 13 corresponding to the spray pipe 4. The spray pipe 4 is set on the upper surface of the test plate 5 through the limiting rings 13, and the scale 6 is set on the side of the spray pipe 4 away from the fixed plate 2. The limiting rings 13 limit the spray pipe 4, and the hydraulic push rod 11 drives the fire extinguisher nozzles of different heights to move to a position horizontal with the spray pipe 4. Then, the spray pipe 4 is connected to the fire extinguisher through the interface, thereby ensuring that the fire extinguisher is at the same height and under the same conditions in each test, thus ensuring the accuracy of the fire extinguisher spray test.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
