[0003] However, the traditional water storage tank is mostly constructed by using concrete material, and water is injected into the water storage tank through specific equipment, but in mountainous areas, due to impassable roads and limited transportation conditions, the construction of the concrete water storage tank faces many challenges, more importantly, the concrete water storage tank often has a water leakage problem in later use, frequent water replenishment and maintenance are needed, and it is not easy to collect rainwater and evaporate, in addition, the construction of the concrete water storage tank needs a large amount of material investment, and because the mountainous terrain is complex, general engineering machinery is difficult to directly reach the construction site, and it is often necessary to repair the road in advance, which not only prolongs the construction period, but also greatly increases the cost, especially in the cold northern region, the concrete water storage tank is more prone to freeze cracking damage in the low-temperature environment in winter.

[0004] For the above-mentioned related technology, the inventor finds that the traditional water storage tank not only cannot automatically collect rainwater as fire extinguishing agent, but also is not easy to transport during construction, and the construction period is long, thereby affecting the use of the forest water storage tank.

[0041] It should be noted that these drawings are simplified schematic diagrams, and only schematically show the basic structure of the present application, and thus only show the relevant components of the present application.

[0042] Referring to Figure-8, the utility model discloses a kind of water reservoirs special for forest fire, comprising: detachable protection cylinder assembly 10, detachable protection cylinder assembly 10 is installed with water storage device 20 in its inside, water storage device 20 includes flexible water storage bag 21 and the filter cover 22 connected at its top, the top of flexible water storage bag 21 is tapered, the inner chamber top of flexible water storage bag 21 is equipped with the anti-evaporation mechanism 23 being connected with filter cover 22, the top edge of flexible water storage bag 21 is connected with extension connection structure 24, extension connection structure 24 is connected with the top end of detachable protection cylinder assembly 10, the bottom side of flexible water storage bag 21 is connected with water delivery mechanism 25, one end of water delivery mechanism 25 extends to the outside of detachable protection cylinder assembly 10, detachable protection cylinder assembly 10 includes a plurality of annular fixed plate pieces 11, two adjacent annular fixed plate pieces 11 are connected by rivet, annular fixed plate piece 11 includes a plurality of arc plates 111 and a plurality of backing plates 112, the both ends of arc plate 111 are integrally formed with trapezoidal block 113 respectively, trapezoidal groove 114 matched with trapezoidal block 113 is formed between adjacent two trapezoidal blocks 113, trapezoidal block 113 on adjacent two arc plates 111 is respectively staggered and is clamped in corresponding trapezoidal groove 114, and adjacent two arc plates 111 and backing plate 112 are connected by bolt respectively.

[0043] Further, flexible water storage bag 21 is made of strong high-molecular flexible material, which is resistant to aging, high and low temperature, and easy to fold, pack, transport and install. The tapered top can optimize water flow distribution and collection, reduce direct impact of water flow on the bag body, prolong service life, and during rainwater collection, the two adjacent annular fixed plate pieces 11 can be connected by rivet or screw. The filter cover 22 filters out impurities such as leaves and dust entering the flexible water storage bag 21, ensuring the cleanliness and hygiene of the water. At the same time, the filter cover 22 can prevent external sharp objects from directly contacting the flexible water storage bag 21, further protecting it from damage, and cooperating with the anti-evaporation mechanism 23, effectively reducing the evaporation loss of water in the flexible water storage bag 21, especially in dry and hot seasons, which helps to maintain sufficient water quantity. The staggered arrangement of trapezoidal blocks 113 and trapezoidal grooves 114 on arc plates 111 allows adjacent two arc plates 111 to be easily clamped together and connected with backing plates 112 by bolts, which simplifies the assembly process and makes it easy for workers to transport. The number and position of annular fixed plate pieces 11 can be adjusted according to actual needs to adapt to flexible water storage bags 21 of different sizes and shapes. In addition, before assembly, the corresponding position of detachable protection cylinder assembly 10 is poured with corresponding cement base for cooperation.

[0044] The extension connecting structure 24 comprises a ring-shaped extension 241 covering the top of the ring-shaped fixed plate 11, and the surface of the ring-shaped extension 241 is provided with a plurality of fixed anchor pieces 242 arranged in a ring shape, and the two ends of each fixed anchor piece 242 are connected with a fastener 243, and the fastener 243 penetrates through the ring-shaped extension 241 and is connected with the top end of the ring-shaped fixed plate 11.

[0045] Further, the fastener 243 is a bolt, a screw or a rivet, and is made of corrosion-resistant materials such as stainless steel, so as to ensure that it will not rust or loosen during long-term use. Through the cooperation of the fixed anchor piece 242 and the fastener 243, the extension connecting structure 24 can be firmly connected with the ring-shaped fixed plate 11, so as to ensure that the flexible water storage bag 21 will not be separated or displaced from the detachable protection cylinder assembly 10 when subjected to external force, thereby effectively fixing the water storage device 20 on the protection cylinder assembly. In addition, the ring-shaped extension 241 and the fixed anchor piece 242 are made of high-strength and corrosion-resistant materials, which can resist external environmental erosion and wear.

[0046] The anti-evaporation mechanism 23 comprises a pipe body 231 and a sealing baffle 232, the bottom side of the pipe body 231 is connected with a mounting plate 233, the mounting plate 233 is symmetrically connected with mounting seats 234 near the bottom side of the pipe body 231, a pin shaft 235 is rotatably connected between the mounting seats 234, one end of the sealing baffle 232 is sleeved on the pin shaft 235 and located between the mounting seats 234, a torsional spring 236 is sleeved on the pin shaft 235, one end of the torsional spring 236 is located at the bottom of the sealing baffle 232, an inclined water flow groove 237 is formed in the top of the sealing baffle 232, and the pipe body 231 is one of a square tube and a round tube.

[0047] Further, when the rainwater flows into the conical top of the flexible water storage bag 21, the gravity of the rainwater gradually increases with the rising water level, and the downward pressure on the sealing baffle 232 increases. When the sealing baffle 232 is subjected to the downward pressure of the rainwater gravity, it swings downward and forms a certain gap with the bottom end of the pipe body 231 to allow the rainwater to flow smoothly into the flexible water storage bag 21 below. When the rainwater flow is small, the gravity generated by the rainwater is not enough to completely open the sealing baffle 232, and is less than the torsional force of the torsional spring 236. At this time, part of the rainwater will flow into the flexible water storage bag 21 through the water flow groove 237 on the sealing baffle 232, ensuring that automatic collection of rainwater can be achieved even when the rainwater flow is small. When collecting rainwater, the torsional spring 236 drives the sealing baffle 232 to tightly contact the bottom end of the pipe body 231, reducing water evaporation and loss and improving water resource utilization efficiency. In addition, in the case of forest fire fighting and other occasions requiring rapid and large water transportation, a round tube may be more suitable because it has small fluid resistance, light weight and easy installation. However, in the case of needing to bear larger pressure or higher stability, such as the support structure of large water storage facilities, a square tube may be more ideal.

[0049] Further, through the cooperation of the inner flange 251, the outer flange 253, the threaded half hole 254 and the through hole 255, the water delivery mechanism 25 can firmly connect the water delivery pipe 252 with the flexible water storage bag 21, ensuring that there is no leakage or loosening during water delivery, and the inner flange 251 and the outer flange 253 are thickened at the corresponding positions of the flexible water storage bag 21, which makes the two flanges clamped more tightly, prevents the pressure from being too large to burst and leak, not only improves the stability of the connection, but also enhances the sealing of the entire water delivery system, effectively preventing the waste of water resources and environmental pollution.

[0050] The top of the detachable protection cylinder assembly 10 is provided with a conical top cover assembly 30, the conical top cover assembly 30 comprises a plurality of sector plates 31 and a plurality of strip plates 32, a water receiving groove 33 is arranged close to the outer circle of the sector plate 31, a plurality of water receiving holes 34 are arranged in the water receiving groove 33, the ends of the adjacent two water receiving grooves 33 coincide with each other, the center of the water receiving groove 33 and the center of the sector plate 31 are located on the same axis, the projection of the water receiving groove 33 is located in the projection of the flexible water storage bag 21, the adjacent two sector plates 31 are connected by bolts on the side facing each other, the inclination angle of the strip plate 32 is the same as the inclination angle of the sector plate 31, the top end of the detachable protection cylinder assembly 10 is provided with a plurality of L-shaped support plates 35 arranged in a ring, the top of the L-shaped support plate 35 is connected with the sector plate 31 by bolts, and one side of the L-shaped support plate 35 is connected with the outer wall of the detachable protection cylinder assembly 10 by bolts.

[0051] Further, the conical top cover assembly 30 provides additional protection for the entire reservoir system, realizes the collection and guidance of rainwater, improves the utilization efficiency of water resources, and enables the rainwater to flow smoothly into the water inlet groove 33 and into the flexible water storage bag 21 through the water inlet hole 34, thereby realizing effective collection of rainwater and avoiding accumulation and leakage of rainwater on the surface of the top cover. At the same time, the projection of the water inlet groove 33 is located within the projection of the flexible water storage bag 21, thereby avoiding waste caused by direct rainwater dripping onto the ground. During assembly of the conical top cover assembly 30, the plurality of fan-shaped plates 31 form a complete conical structure, and the strip-shaped plates 32 are connected between adjacent two fan-shaped plates 31, thereby enhancing the stability and integrity of the top cover and facilitating transportation and assembly.

[0052] The implementation principle of the embodiment is as follows: in use, the staff transports the arc-shaped plates 111, the flexible water storage bag 21 and other components for building the reservoir to the corresponding position in the mountain area, then sequentially assembles the arc-shaped plates 111, connects the two assembled arc-shaped plates 111 and the gasket plate 112 through bolts, sequentially completes assembly of the annular fixed plate member 11, installs the bottommost annular fixed plate member 11 and the cement base, then sequentially assembles the annular fixed plate member 11 to form the detachable protection cylinder assembly 10, installs the flexible water storage bag 21 inside the detachable protection cylinder assembly 10, then installs the extension connecting structure 24 on the top of the uppermost annular fixed plate member 11 through cooperation of the fixing anchor 242 and the fastener 243, ensures that the flexible water storage bag 21 does not separate from or displace the detachable protection cylinder assembly 10 when subjected to external force, and if the customer needs, continues to assemble the conical top cover assembly 30, connects the fan-shaped plates 31 and the strip-shaped plates 32 into the conical top cover assembly 30 through bolts, correctly installs the L-shaped support plate 35 to provide support for the conical top cover assembly 30, thereby completing construction of the reservoir, and making the forest fire-fighting special reservoir more flexible and efficient in complex terrains such as mountain areas.
