Description

Technical Field

[0001] The utility model relates to the technical field of water storage tanks for fire trucks, in particular to a water storage tank for a top water supply fire truck. Background Art

[0002] Fire trucks, also known as fire engines, are vehicles designed and manufactured to be suitable for firefighters to ride, equipped with various firefighting equipment or fire extinguishing agents, and used by firefighting forces for firefighting, auxiliary firefighting or fire rescue. They are usually double-row vehicles, and fire departments in most countries, including China, will also use them for other emergency rescue purposes. Fire trucks can transport firefighters to the disaster site and provide them with a variety of tools for disaster relief missions.

[0003] Fire truck water tanks generally use bottom water supply. During the water supply process, the pressure gradually increases with the increase of water volume in the water tank. Therefore, a special high-pressure water injection device is required to provide sufficient pressure to complete the entire water supply process. Therefore, during the firefighting process, once the water tank is insufficient, it is difficult to supply water to the water tank in time.

[0004] For this purpose, we designed a top-fed fire truck water storage tank. Utility Model Content

[0005] The utility model aims to solve the problem of insufficient water supply function in the prior art and provides a water storage tank for a top water supply fire truck.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A water storage tank for a top water supply fire truck comprises a tank body, the tank body is provided with at least one water inlet pipe for injecting water, one end of the water inlet pipe is provided with a cover for temporarily sealing the pipe, a buffer net box for buffering the water flow of the water inlet pipe is provided in the tank body corresponding to the output end of the water inlet pipe, the buffer net box is provided with a first mesh for reducing the impact of the water flow, the buffer net box is provided with a plurality of connectors for connecting to the tank body, and the water inlet pipe is provided with a screw cover for sealing.

[0008] Preferably, the opening cover is rectangular and fixedly connected to the output end of the water inlet pipe via an auxiliary shaft. A first sealing ring for reducing water overflow is provided on the box body, and the first sealing ring abuts against the water inlet pipe.

[0009] Preferably, the buffer box is symmetrically provided with support bars, and the support bars are fixedly connected to the side walls of the buffer box by welding, and the buffer box is provided with a plurality of buffer meshes for reducing the impact of water flow.

[0010] Preferably, the first gauze is fixedly connected to the support bar by fasteners, and the support bar is provided with a second gauze, a third gauze and a fourth gauze for reducing the impact of water flow.

[0011] Preferably, the second gauze, the third gauze and the fourth gauze are arranged around the first gauze in sequence from top to bottom, and the opening diameters of the second gauze, the third gauze and the fourth gauze are gradually reduced from top to bottom.

[0012] Preferably, the connecting pieces are linearly arranged at the bottom of the buffer cage, and are fixedly connected to the bottom of the cage by welding.

[0013] Preferably, a thread groove is formed at one end of the water inlet pipe, and a plurality of threaded threads are provided on the screw cover, the threaded threads are matched with the thread groove, and a second sealing ring for reducing water overflow is provided on the screw cover.

[0014] The beneficial effects of the utility model are:

[0015] 1. The water tank of the fire truck with top water supply described in the utility model can directly supply water to the water tank from the top through the water inlet pipe. An ordinary water pump or faucet can be used to complete the task. No special high-pressure water injection device is required. It is convenient to supply water to the water tank at any time, which can effectively solve the problem of insufficient water storage in the water tank and difficulty in timely water supply during firefighting.

[0016] 2. The utility model provides a buffer net box and a buffer mesh, so that after the water flow in the water inlet pipe enters the box, the damage to the box caused by the impact of the water flow can be greatly reduced. At the same time, the buffer mesh can continuously disperse the impact of the water flow to the surroundings, which can effectively avoid the strong fluctuation of the water flow in the box caused by the impact of the water flow. When the fire truck moves, the buffer net box can greatly reduce the fluctuation of the water flow caused by the bumps, thereby reducing the phenomenon of water flow impact.

[0017] 3. The utility model reduces the impact of the water gushing out of the water inlet pipe by setting the first gauze and the fourth gauze. After being blocked by multiple gauze, the speed of the current water flow can be greatly reduced, reducing the damage to the box body caused by the impact of the water flow. The fourth gauze can disperse the water flow into more small water flows, further reducing the phenomenon of too fast water flow. The air circulation in the process of water inlet pipe input can be improved through the opening cover to avoid the reduction of the efficiency of water replenishment in the box due to excessive pressure in the box. The sealing effect of the water inlet pipe can be improved through the threaded cover to avoid the water flow from the water inlet pipe spraying out during the movement of the fire truck, thereby reducing the capacity of the water body in the box.

[0023] Reference Figure 1-Figure 4 A water storage tank for a top water supply fire truck comprises a tank body 1. The tank body 1 is a fire water tank in a fire truck in the prior art. The amount of water stored in the tank body can be used as a powerful means to reduce the pressure of the fire in the current vehicle body. The water inlet pipe 2 is the only channel for supplying water to the top of the fire truck. At the same time, the number of the water inlet pipes 2 depends on the layout structure of the current fire truck, and there is no less than one water inlet pipe 2. In this embodiment, two water inlet pipes are arranged, which can greatly improve the water injection efficiency and also reduce the low water injection efficiency of a single water pipe.

[0024] A cover 3 for temporarily sealing the pipe is provided at one end of the water inlet pipe 2. The cover 3 is mainly used to reduce the sealing work at one end of the water inlet pipe 2. When water flows through, it will automatically open to prevent foreign matter from entering the water inlet pipe 2. The cover 3 is rectangular, which can increase the coverage area of ​​the water inlet pipe 2. Even if the fire truck is displaced due to bumps, shaking, etc. during driving, it will not affect its sealing effect. The cover 3 is fixedly connected to the output end of the water inlet pipe 2 through an auxiliary shaft. The auxiliary shaft is an elastic component and is a prior art, which is convenient for the cover 3 to rotate due to water flow. When the water flow is reduced or stopped, the cover 3 can be reset. A first sealing ring is provided on the box body 1 to reduce water overflow. The first sealing ring is provided at the connection between the top of the box body 1 and the water inlet pipe 2 to prevent water from overflowing from the connection due to pressure, and the first sealing ring is against the water inlet pipe 2, and the first sealing ring is adsorbed on the outer wall of the water inlet pipe 2.

[0025] Two buffer boxes 4 for buffering water flow are arranged in the box body 1. The buffer boxes 4 are the main components for reducing the impact of water flow. The number of the buffer boxes 4 depends on the number of water inlet pipes 2, and the buffer boxes 4 are directly opposite to the output ports of the water inlet pipes 2, so as to centrally buffer the water flow. Two groups of support bars 6 are symmetrically arranged on the buffer boxes 4. The support bars 6 are composed of a plurality of folding strips, which can effectively improve the suspension effect. The support bars 6 are fixedly connected to the side walls of the buffer boxes 4 by welding. Welding can improve the connection strength between the support bars 6 and the sides of the buffer boxes 4, and avoid excessive gravity of the suspension components, which may cause the connection of the support bars 6 to deform and fall off, thereby improving the service life of the support bars 6. The buffer boxes 4 are provided with a plurality of buffer screens 5 for reducing the impact of water flow. Figure 3 The buffer screen 5 has a relatively large overall opening diameter and is arranged around the buffer mesh box 4, which can effectively improve the effect of water flow dispersion and can minimize the impact of water flow in conjunction with other screens.

[0026] The buffer box 4 is provided with a first gauze 7 for reducing the impact of water flow. The main opening diameter of the first gauze 7 is the same as that of the buffer gauze 5, and it is the first obstacle for the water flow to contact the buffer box 4. The first gauze 7 is fixedly connected to the support bar 6 through a fastener. The fastener is a connecting member of the gauze component, and the gauze component is suspended on the support bar 6. The support bar 6 is also provided with a second gauze 8, a third gauze 9 and a fourth gauze 10 for reducing the impact of water flow in sequence. The second gauze 8, the third gauze 9 and the fourth gauze 10 are all arranged around the first gauze 7 in sequence and fixed on the support bar 6 through fasteners. At the same time, the opening diameters of the three are gradually reduced from top to bottom. The smaller the opening diameter, the more it can improve the mitigation efficiency of the water flow impact. According to the size of the buffer box 4, the fifth gauze can be further arranged. Through the layer-by-layer buffering and decomposition of the multi-layer gauze, the impact force of the water flow can be gradually reduced to avoid a large impact on the box body. If the gauze is damaged and falls off during use, the presence of the buffer mesh box 4 can also prevent the fallen gauze from falling into the box body 1, causing clogging of the water tank and affecting the fire-fighting work.

[0027] The buffer net box 4 is provided with a plurality of connectors 11 for connecting the box body 1. The connectors 11 are welded to the bottom of the buffer net box 4 and are mainly used to limit the position of the buffer net box 4 in the box body 1. The connectors 11 are linearly arranged at the bottom of the buffer net box 4. The number of connectors 11 depends on the specifications of the buffer net box 4. The connectors 11 and the buffer net box 4 can offset part of the impact force of the water and reduce the pressure of the water flow on the inner wall of the box body 1 during the shaking of the vehicle body.

[0028] A screw cover 12 for sealing is provided on the water inlet pipe 2. The screw cover 12 is used to seal one end of the water inlet pipe 2 to prevent foreign matter in the environment from entering the water inlet pipe 2. A threaded groove is provided at one end of the water inlet pipe 2, and a plurality of threaded wires 13 are provided on the screw cover 12. The threaded wires 13 are adapted to the threaded groove. The threaded groove and the threaded wires 13 are prior art. A second sealing ring for reducing water overflow is provided on the screw cover 12. The second sealing ring can reduce water overflow.

[0029] The working principle of the utility model is as follows: the water supply unit is connected to one end of the water inlet pipe 2. After the water flows into the box 1 from the water inlet pipe 2, the impact of the water flow will be gradually reduced to a minimum under the obstruction of the first mesh 7 and the fourth mesh 10 in the buffer net box 4, thereby reducing the damage caused by the water flow impact to the box 1. At the same time, when the vehicle body shakes, the buffer net box 4 can reduce the fluctuation of the water body, which is beneficial to the stability of the vehicle body. Even when driving on a road with relatively poor road conditions, the fluctuation of the water body can be effectively reduced, which is more suitable for fire rescue in different conditions.
