Description

Technical field:

[0001] The utility model relates to the technical field of fire protection, in particular to a fire hydrant enriched water column collecting device. Background technology:

[0002] The full water column of a fire hydrant system is an important indicator of the system. It has important applications in the design, construction, testing, and acceptance stages. It is also an important parameter for measuring the fire extinguishing and water supply capabilities of a fire hydrant system. It is necessary to test whether the full water columns tested from multiple fire hydrants meet the specifications and design requirements in turn, and to use a fire hydrant full water column collection device to collect and read the water columns.

[0003] The existing fire hydrant full water column collection device is mainly composed of a collection box and a circular hole. When the water gun is a certain distance away from the collection box, the water enters the collection box along the circular hole. The water in the collection box is read to determine whether the fire water column meets the demand. The water entering the collection box from the circular hole falls quickly into the collection box. The water flow rate is relatively large, which has a large impact on the water surface formed in the collection box, causing large fluctuations on the water surface. It is necessary to wait for the water to stand for a period of time before readings can be taken, which prolongs the time for multiple fire hydrant test shooting full water column detection. Utility model content:

[0004] To this end, the purpose of the utility model is to provide a fire hydrant enriched water column collection device to overcome the existing technology because the existing fire hydrant enriched water column collection device is mainly composed of a collection box and a circular hole. After the water gun is a certain distance away from the collection box, the water enters the collection box along the circular hole, and the water in the collection box is read to determine whether the fire water column meets the demand. The water entering the collection box from the circular hole falls quickly into the collection box, and the water flow rate is relatively large. The impact on the water surface formed in the collection box is relatively large, causing large fluctuations in the water surface. It is necessary to wait for the water to stand for a period of time before readings can be taken, which prolongs the time for testing multiple fire hydrants to enrich the water column.

[0005] The utility model is implemented by the following technical solutions:

[0006] A fire hydrant enriched water column collection device comprises a collection box, the bottom surface of the collection box is fixedly connected to a drain pipe, the side wall of the drain pipe is fixedly connected to a valve, the side wall of the collection box is provided with a circular hole, a flow guide mechanism is fixedly connected inside the collection box, a plurality of water outlet pipes are fixedly connected to the bottom surface of the flow guide mechanism, the water outlet pipes comprise a plurality of vertical pipes arranged from bottom to top, the top vertical pipe is fixedly connected to the flow guide mechanism, adjacent vertical pipes are fixedly connected to inclined pipes, and the inclination angles of the plurality of inclined pipes gradually increase from bottom to top.

[0007] Preferably, the included angle between the vertical tube and the inclined tube is 91°-120°.

[0012] The advantages of the utility model are as follows: a plurality of vertical pipes are arranged at the bottom end of the guide mechanism, and adjacent vertical pipes are fixedly connected to each other through inclined pipes with an inclination angle gradually increasing from bottom to top. Water passes through the vertical pipes and the inclined pipes in sequence along the guide mechanism and finally falls into the collection box.

[0022] like Figure 1-Figure 3 As shown, the utility model provides the following technical solutions: a fire hydrant enriched water column collection device, comprising a collection box 1, a drain pipe 2 is fixedly connected to the bottom of the collection box 1, a valve is fixedly connected to the side wall of the drain pipe 2, a circular hole 3 is opened on the side wall of the collection box 1, a flow guide mechanism is fixedly connected inside the collection box 1, a plurality of water outlet pipes are fixedly connected to the bottom of the flow guide mechanism, the water outlet pipes include a plurality of vertical pipes 6 arranged from bottom to top, the top vertical pipe 6 is fixedly connected to the flow guide mechanism, adjacent vertical pipes 6 are fixedly connected with inclined pipes 7, and the inclination angles of the plurality of inclined pipes 7 gradually increase from bottom to top.

[0023] The included angle between the vertical pipe 6 and the inclined pipe 7 is 91°-120°, which is convenient for water to flow out.

[0024] The cross section of the inner bottom surface of the collection box 1 is V-shaped, which is convenient for draining the water flow in the collection box 1 .

[0025] Please combine Figure 1As shown, during use, the device is used instead of the traditional collecting device to collect the test water column of the fire hydrant. The test water column of the fire hydrant is aimed at the circular hole 3 for experiment. The water column falls to the top surface of the guide mechanism through the circular hole 3, and then flows along the guide mechanism to enter into multiple vertical pipes 6 and inclined pipes 7 in turn, and finally falls to the bottom of the collection box 1. The multiple vertical pipes 6 and inclined pipes 7 are arranged in a stepped manner to achieve deceleration of the water flow, reduce the impact on the water surface, thereby reducing the fluctuation amplitude of the water surface formed in the collection box, shortening the time required for the water surface to stand still, and shortening the time for detecting the test water column of the fire hydrant. The inclination angle of the multiple inclined pipes 7 increases gradually from bottom to top, extending the water flow path, thereby further reducing the water flow velocity while preventing water accumulation in the inclined pipe 7. Readings are taken after the water surface is still. After the readings are completed, the valve at the side end of the drain pipe 2 is opened to discharge the water in the collection box 1 from the drain pipe 2.

[0026] Please combine Figure 1 , Figure 2 As shown, an embodiment of the guide mechanism includes an inclined plate 4 and a plurality of chutes 5. The inclined plate 4 is fixed to the inner wall of the collecting box 1. The chutes 5 are opened on the top surface of the inclined plate 4. The chutes 5 are connected to the top vertical pipe 6. The inclined plate 4 is fixedly connected to the top vertical pipe 6.

[0027] The inclined plate 4 is arranged in an inverted V shape to facilitate the flow of water.

[0028] The cross-section of the chute 5 is serpentine, which prolongs the water flow path and reduces the water flow velocity.

[0029] Please combine Figure 1 As shown, during use, the fire hydrant is tested by aiming a full water column at the circular hole 3 for testing. The water column passes through the circular hole 3 and falls onto the top surface of the inclined plate 4. The water flows gradually along the chute 5, and then flows into the vertical pipe 6 along the chute 5, and then flows into the collection box 1 along the vertical pipe 6 and the inclined pipe 7 in turn, and then the reading is taken.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
