Description

Technical Field

[0001] This utility model relates to the field of fire protection building technology, and in particular to a multi-trough rectangular pool. Background Technology

[0002] A fire pool is a man-made water storage facility for fixed or mobile fire pumps to draw water from.

[0003] A fire pool shall be provided if any of the following conditions are met: the municipal water supply network or the inlet pipe cannot meet the design flow rate of indoor and outdoor fire water supply; a single fire water supply or only one inlet pipe is used, and the design flow rate of outdoor fire hydrants is greater than 20L / s or the building height is greater than 50m; or the design flow rate of municipal fire water supply is less than the design flow rate of indoor and outdoor fire water supply of the building.

[0004] However, the reserve water stored in the fire pool for a long time will continuously decrease due to evaporation. Therefore, it is impossible to guarantee that the water level will be in the ideal position when needed. It is necessary to manually monitor and replenish the water pool regularly so that the reserve water in the fire pool can be smoothly discharged when needed, which greatly increases labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a multi-slot rectangular pool to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows: This utility model provides a multi-trough rectangular pool, including a pool body comprising at least one inner water storage tank and at least two outer water storage tanks, with the inner and outer water storage tanks connected sequentially. The top of each outer water storage tank is connected to the outside and is rotatably fitted with a cover. The middle of the cover is hinged to the connection point of the two outer water storage tanks. A water collection hopper is movably mounted on the cover. A compression spring connected to the cover below the water collection hopper is fixed inside each outer water storage tank. A pulley is fixed on the other side of the cover opposite to the compression spring, and a pull rope constrained by the pulley is also provided. One end of the pull rope extends along the axis of the cover towards the compression spring and is fixedly connected to the connection point between the cover and the compression spring. A counterweight is detachably fixed on the other end.

[0007] In one embodiment, a mounting bracket is fixedly provided on the cover, and the water collection hopper is rotatably mounted on the mounting bracket.

[0008] In one embodiment, two symmetrically distributed balance springs are fixedly provided at the bottom of the water collection hopper, and the other end of the balance springs is fixedly connected to the cover.

[0009] In one embodiment, a guide is hinged to the bottom of the cover, and a connector is hinged to the end of the guide away from the cover, the connector being fixedly connected to the top of the compression spring.

[0010] In one embodiment, the water collection hopper has a downward-through water inlet in the middle, and a water guide pipe is embedded in the water inlet. The other end of the water guide pipe extends into the outer water storage tank.

[0011] In one embodiment, sealing plates are fixed on both sides of the opening of the external water tank, and sealing baffles are fixed on both sides of the cover, with the sealing baffles being separable and pressing against the sealing plates.

[0012] In one embodiment, the bottom of the cover has a cable tray for threading a pull cord.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following: In this invention, the rainwater collection hopper collects rainwater during rain, allowing it to accumulate. As rainwater continues to flow in, the weight of the collection hopper increases, pressing the cover downwards and causing it to rotate, exposing the top of the outer water storage tank. Rainwater can then directly enter the outer water storage tank through the exposed opening, ultimately enabling the outer water storage tank to collect rainwater during rainy days, thus extending the cycle of manual water replenishment and reducing labor costs. When the cover rotates and tilts to a certain angle, the rainwater in the collection hopper pours into the outer water storage tank, reducing the weight of the collection hopper. The cover then rotates back to reseal the outer water storage tank, preventing excessive external dirt from entering the outer water storage tank when it is open for extended periods.

[0024] Reference Figures 1-3A multi-trough rectangular pool includes a pool body 1, which includes at least one inner water storage tank 2 and at least two outer water storage tanks 3, with the inner water storage tank 2 and the outer water storage tanks 3 connected sequentially. The top of the outer water storage tanks 3 is open to the outside and is rotatably equipped with a cover 4. The middle of the cover 4 is hinged to the connection point of the two outer water storage tanks 3. A water collection hopper 5 is movably mounted on the cover 4. A compression spring 6 is fixedly mounted on the outer water storage tank 3 and connected to the cover 4 below the water collection hopper 5. A pulley 7 is fixedly mounted on the other side of the cover 4 opposite to the compression spring 6, and a pull rope 8 is also provided, which is constrained by the pulley 7. One end of the pull rope 8 extends along the axis of the cover 4 toward the compression spring 6 and is fixedly connected to the connection point of the cover 4 and the compression spring 6. A counterweight 9 is detachably fixed on the other end. With this configuration, when it is not raining, the cover 4 is in a balanced position through the hinge point. At this time, the compression spring 6 pushes the cover 4 upward to provide a closing force. The counterforce provided by the counterweight 9 also simultaneously assists in balancing the cover 4, causing the cover 4 to tend to cover the top of the outer water storage tank 3, thereby reducing the evaporation of water in the pool 1 and the entry of external debris into the pool 1. During rainfall, rainwater first enters the water collection hopper 5. As the water volume in the water collection hopper 5 increases, its weight also gradually increases. Since the weight of the water collection hopper 5 is concentrated on one side of the cover 4, as the water collection hopper 5 continues to press down, the side of the cover 4 equipped with the water collection hopper 5 begins to rotate downward, while the other side lifts upward, thus opening the cover 4 and exposing the top of the outer water storage tank 3, allowing rainwater to directly enter the outer water storage tank 3. In this way, the outer water storage tank 3 can collect rainwater on its own, and the stored water can flow to the inner water storage tank 2, causing the water levels of multiple water storage tanks in the pool 1 to rise together, increasing the cycle of manual water replenishment, and allowing staff to estimate how much water is left in the entire pool 1 based on the rainfall, thus reducing labor costs.

[0025] In one specific embodiment, when the cover 4 rotates, the pull rope 8 and its connection point move downwards, and the counterweight 9 moves upwards to assist in adjusting the rotation angle and prevent the cover 4 from rotating too fast and damaging the mechanism. At the same time as the cover 4 rotates, the compression spring 6 is compressed and begins to store mechanical energy. When the cover 4 rotates to a certain angle, the rainwater in the water collection hopper 5 can be poured into the outer water storage tank 3. After the weight is reduced, the downward pressure force of the water collection hopper 5 is lost, the compression spring 6 releases mechanical energy and rebounds, and the counterweight 9 also applies downward gravity at this time to drive the cover 4 to rotate, so that the cover 4 covers the top of the outer water storage tank 3 again. In this way, the opening time of the cover 4 can be controlled to avoid excessive external debris entering the outer water storage tank 3 due to the long opening time, and the operation process of manually closing the cover 4 is also eliminated.

[0026] In one specific embodiment, the rotation of the cover 4 relies entirely on the weight of the water and mechanical force to achieve on / off adjustment, reducing energy consumption and maintenance costs. The system automatically responds to changes in water volume, improving water resource management efficiency. In practical use, the detachable design of the counterweight 9 makes it convenient for staff to replace it, allowing the weight of the counterweight 9 to match the local rainfall intensity or to be adjusted according to seasonal climate changes, thereby improving the adaptability and water utilization efficiency of this invention. The design of at least one inner tank and at least two outer tanks can expand to more tanks, suitable for different scales.

[0027] Reference Figure 2 A mounting bracket 10 is fixed on the cover 4, and the water collection hopper 5 is rotatably mounted on the mounting bracket 10. With this configuration, during the rotation of the cover 4, the water collection hopper 5 can rotate around the hinge point with the mounting bracket 10 as the center of gravity changes. When the cover 4 rotates to a certain angle, the bottom of one side of the water collection hopper 5 directly contacts the top of the cover 4 due to the tilt angle. As a result, the tilt angle of the water collection hopper 5 is greater than that of the cover 4. The rainwater in the water collection hopper 5 will flow outward first due to the tilt and enter the outer water storage tank 3 along the cover 4. At this time, the cover 4 has not rotated to the maximum angle, so the top opening of the outer water storage tank 3 is not exposed much, which reduces the probability of external debris entering the outer water storage tank 3. As the rainfall increases or the amount of rainwater in the water collection hopper 5 increases, the cover 4 continues to rotate until it is fully opened.

[0028] Reference Figure 2 Two symmetrically distributed balance springs 11 are fixed at the bottom of the water collection hopper 5. The other end of the balance spring 11 is fixedly connected to the cover 4. With this arrangement, the balance spring 11 can provide a certain support force to the bottom of both sides of the water collection hopper 5, so that the water collection hopper 5 can be in a balanced state when the cover 4 is not flipped. When rainwater begins to accumulate in the water collection hopper 5, the center of gravity of the water collection hopper 5 changes as the cover 4 tilts. The rainwater accumulated in the water collection hopper 5 begins to push against one side. When the pushing force is greater than the support force provided by the balance spring 11, the water collection hopper 5 begins to flip itself to pour some of the rainwater into the outer water storage tank 3.

[0029] Reference Figure 2A guide 17 is hinged to the bottom of the cover 4. A connector 18 is hinged to the end of the guide 17 away from the cover 4. The connector 18 is fixedly connected to the top of the compression spring 6. With this configuration, as the cover 4 rotates, the guide 17 also deflects around the hinge point with the cover 4 and applies a downward pressure force. This force is then transmitted to the compression spring 6 through the rigid connection of the connector 18. However, due to the adaptive adjustment of the direction of the force applied by the guide 17 after its own deflection, the pressure force of the connector 18 below the compression spring 6 always remains vertically downward. This prevents the compression spring 6 from radially bending due to the deviation of the force direction. This not only protects the compression spring 6 from damage due to frequent deformation, but also ensures that the upward elastic force provided by the compression spring 6 can be applied to the cover 4 in the vertical direction as much as possible, reducing the waste of kinetic energy during the transmission process.

[0030] Reference Figures 1-3 The water collection hopper 5 has a downward-through water inlet 12 in the middle, and a water guide pipe 13 is embedded in the water inlet 12. The other end of the water guide pipe 13 extends into the outer water storage tank 3. With this configuration, after rainwater falls into the water collection hopper 5, some of the rainwater flows into the outer water storage tank 3 through the water inlet 12 and the water guide pipe 13. This allows some of the rainwater to be diverted before the cover 4 is triggered to rotate, thus preventing the water collection hopper 5 from becoming too heavy during light rainfall and causing the cover 4 to open accidentally. The remaining rainwater continues to accumulate in the water collection hopper 5 until the weight reaches the trigger threshold. When the rainfall intensity increases, the water level in the water collection hopper 5 exceeds the height of the water inlet 12, causing the water volume in the water collection hopper 5 to increase rapidly and the gravity to increase rapidly. This causes the accumulated gravity to drive the cover 4 to overcome the resistance of the compression spring 6 and the counterweight 9 and rotate downward, opening the top of the outer water storage tank 3.

[0031] In one specific embodiment, since the water inlet 12 is designed in the middle of the water collection hopper 5, the rainwater in the water collection hopper 5 will only be diverted from the water inlet 12 after it has accumulated and submerged the water inlet 12. This can prevent debris falling into the water collection hopper 5 from directly blocking the water inlet 12, including but not limited to fallen leaves. In addition, the opening of the water inlet 12 is designed to be inclined, which further reduces the probability of debris blocking the water inlet 12.

[0032] Reference Figures 1-3 Sealing plates 14 are fixed on both sides of the opening of the outer water tank 3, and sealing baffles 15 are fixed on both sides of the cover 4. The sealing baffles 15 can be separated and pressed against the sealing plates 14. With this arrangement, when the cover 4 is closed, the sealing baffles 15 are pressed tightly against the sealing plates 14 under the action of the compression spring 6. An elastic sealing strip is provided between the sealing baffles 15 and the sealing plates 14. After being pressed, it deforms and fills the micro gaps to form a two-way barrier, improve the sealing effect, and further reduce the evaporation of water stored in the outer water tank 3 and the entry of external dirt into the outer water tank 3.

[0033] Reference Figure 2 The bottom of the cover 4 is provided with a cable tray 16 for the pull rope 8 to pass through. With this configuration, one end of the pull rope 8 is fixedly connected to the counterweight 9 and then constrained to the pulley 7. The other end passes through the cable tray 16 and is connected to the other side of the cover 4 away from the pulley 7. When the cover 4 is tilted, the pull rope 8 can move horizontally along the cable tray 16. Under the constraint of the cable tray 16, the pull rope 8 is prevented from shifting during the movement and pulling on other parts.

[0034] In one specific embodiment, the pool body 1 is made of reinforced concrete, which has the following advantages: First, reinforced concrete can withstand external loads such as soil pressure and groundwater buoyancy, and can effectively resist the infiltration of internal sewage, reducing the risk of leakage and avoiding pollution of groundwater and surrounding soil. Furthermore, concrete itself is corrosion-resistant and anti-aging, and with the reinforcement of steel bars, the service life of the pool body can reach more than 70 years, far exceeding that of materials such as plastic and glass, reducing later replacement costs. Second, whether in soft soil foundations, high water levels, or cold regions, reinforced concrete pool bodies can adapt to the environment through reasonable design, are not prone to cracking due to foundation settlement or temperature changes, and can be directly buried in areas with heavy vehicle traffic, such as roads and parking lots, without additional reinforcement. In contrast, materials such as plastic require careful environmental considerations. Thirdly, the hard surface of reinforced concrete can resist the pressure of biogas and the impact of debris inside the pool, reducing maintenance needs. The inner wall can be smoothed to reduce dirt adhesion, making it easy to clean regularly without structural damage caused by mechanical operations during cleaning. Fourthly, the density of concrete itself, combined with waterproofing during construction, can effectively prevent sewage leakage, protecting groundwater resources and soil ecology. Reinforced concrete is mainly composed of natural or industrial materials such as cement, sand, and steel bars, without releasing harmful chemicals. It can also be recycled after disposal, with minimal environmental impact. Fifthly, for large or irregularly shaped pools, on-site casting can be used to adapt to different site sizes. Small pools can be prefabricated and hoisted, shortening the construction cycle. The volume and structure can be flexibly designed according to the number of users and usage scenarios to meet different sewage discharge requirements.

[0035] In one specific embodiment, the rectangular pool body 1 can solve the problem of water leakage at the joints caused by the non-integral molding of the circular pool body 1 in the existing market, and effectively improve the compressive strength and impermeability of the pool body 1, avoiding the problem of the circular pool body easily collapsing when it is topped by heavy vehicles. At the same time, the protective layer thickness of the rectangular pool body 1 is greater than that of the circular one, which not only improves its corrosion resistance, but also greatly reduces the carbonation process of concrete and extends the service life of the entire pool body 1.

[0036] In one specific embodiment, the pool body 1 of this utility model is 13 meters long, 2.8 meters wide, and 0.3 meters thick. After structural calculation, this size has the advantages of low total cost and fast construction speed while meeting the requirements of quality, use and structural safety. It is generally half the construction period of conventional cast-in-place pool bodies, and can greatly reduce the risk of safety accidents in deep foundation pit projects. It can be widely promoted.
