And the mounting seat is fixedly connected with the movable seat through a shock absorber. According to the shock absorption moving mechanism, when the mounting height of the automatic water cannon is driven to be adjusted, the shock absorber between the mounting seat and the moving seat is used for absorbing and reducing recoil force instantly generated when the automatic water cannon is started, so that the recoil force of the automatic water cannon suddenly and instantly impacts the moving seat and the power source assembly; and the recoil force is slowly and transitionally applied to the moving seat and the power source assembly, so that mechanical damage to the power source assembly caused by instantaneous impact of the recoil force is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment detection, and more specifically refers to a shock-absorbing mobile mechanism used for automatic water cannon spraying test. Background Art

[0002] Automatic water cannon is a fire-fighting device widely used in automatic tracking and positioning jet fire extinguishing systems. It uses automatic control to achieve indoor and outdoor fixed jet fire extinguishing. The performance parameter detection of automatic water cannon mainly includes water pressure, flow rate, maximum protection radius, jet radius and monitoring radius, and these parameters are closely related to the installation height of the automatic water cannon.

[0003] To this end, the applicant provides an automatic water cannon spray test device, which adopts a tower frame with multiple turret platforms from top to bottom, and sets up a mounting for installing an automatic water cannon on each turret platform, and a lifting mechanism that drives the mounting seat to perform vertical lifting. The automatic water cannon spray test device provided by the applicant solves the problem that the existing water cannon installation height span is large (the installation span ranges from 6 to 25 meters), and its lifting mechanism enables the automatic water cannon to have better and more installation height adjustments, making the entire experiment setting conditions, parameters and scenarios more comprehensive.

[0004] However, when the applicant put the test device into use, he found that the test device was suitable for some automatic water cannons with relatively moderate or smaller calibers and injection pressures. Once some automatic water cannons with larger calibers or higher injection pressures were tested, the automatic water cannons would generate a large instantaneous recoil at the moment of injection, and the moment the recoil was generated, it would directly act on the mounting seat and the lifting mechanism. As a result, the selection of the lifting mechanism must meet the requirements of having a certain rigid load capacity and elastic load force. Otherwise, in frequent and multiple tests, the frequent instantaneous recoil will cause unavoidable additional damage to the transmission mechanism of the lifting mechanism, thereby significantly increasing the cost of the lifting mechanism. Utility Model Content

[0005] The utility model aims to provide a shock-absorbing mobile mechanism for automatic water cannon spraying test to solve the above problems.

[0006] The utility model adopts the following technical solutions:

[0007] A shock-absorbing mobile mechanism for an automatic water cannon spray test comprises a plurality of vertically arranged guide slide bars, a mobile seat movably mounted on the guide slide bars, and a power source assembly for driving the mobile seat to move. The mobile seat is provided with a mounting seat for mounting the automatic water cannon, and the mounting seat and the mobile seat are fixedly connected via a shock absorber.

[0008] Furthermore, the mounting seat is located below the moving seat.

[0009] Furthermore, the shock absorber is a plurality of spring shock absorbers, and two ends of the spring shock absorber are fixedly connected to the mounting seat and the movable seat respectively.

[0010] Furthermore, the power source assembly is a screw lifting mechanism or a lifting hydraulic cylinder.

[0011] Preferably, the screw lifting mechanism comprises a screw, a slide seat mounted on the screw and a servo motor for driving the screw to rotate, and the slide seat is fixedly connected to the moving seat.

[0012] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0013] The utility model adopts a shock-absorbing moving mechanism to drive and adjust the installation height of the automatic water cannon. At the same time, a shock absorber is arranged between the installation seat and the moving seat. The shock absorber is used to absorb and slow down the recoil force instantly generated when the automatic water cannon is turned on, so that the recoil force of the automatic water cannon is changed from suddenly and instantaneously impacting the moving seat and the power source component to being slowly and transitionally applied to the moving seat and the power source component, thereby avoiding mechanical damage to the power source component caused by the instantaneous impact of the recoil force.

The moving seat 53 is provided with a mounting seat 12 for mounting an automatic water cannon 40. The mounting seat 12 can be located above or below the moving seat 53. In this embodiment, in order to better test the automatic water cannon 40, the conventional mounting method of the automatic water cannon 40 is adopted, that is, the mounting seat 12 is preferably located below the moving seat 53.

[0026] The main pipeline 21 is connected to the water outlet of the water pump 30, and a DN100 flow meter 23 is provided on the main pipeline 21 in the direction of the water outlet of the water pump 30. Considering that the water used for firefighting test may be an open-air pool or circulating water, the utility model also connects a filter (not shown) to the water inlet of the water pump 30 to filter impurities in the firefighting water.
