Technical Field

[0001] This application relates to the field of deep-buried water tank technology, and in particular to an anti-buoyancy deep-buried water tank. Background Technology

[0002] Deep-buried water tanks are a common type of water supply and drainage facility. These tanks, buried deep underground, are often used to collect and store wastewater for centralized discharge. Currently, deep-buried water tanks are commonly made of fiberglass, metal, precast concrete, or cast-in-place reinforced concrete. The water storage capacity and geometric dimensions can be customized to meet specific needs.

[0003] These types of water tanks are often buried deep underground, firstly to save space, and secondly to utilize gravity for convenient wastewater collection. However, due to significant fluctuations in the water level inside the tank, and sometimes even when the tank is empty, they are susceptible to the influence of groundwater. For example, during the rainy season or in southern regions, rising groundwater levels can exert a significant buoyancy on the tank, often resulting in instances where the tank is squeezed and deformed or floats to the surface.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0038] The following will be combined with the appendix Figure 1 A detailed description of an anti-buoyancy deep-buried water tank according to the present invention is provided below.

[0039] A buoyancy-resistant deep-buried water tank includes a tank body 1 and an anti-buoyancy device;

[0040] The anti-buoyancy device includes a connecting pipe 2 horizontally installed at the bottom of the water tank body 1. One end of the connecting pipe 2 is connected to the inner space of the water tank body 1, and the other end is connected to the outer space of the water tank body 1.

[0041] A piston 6 is installed inside the connecting pipe 2 to block the end of the connecting pipe 2 that connects to the outer space of the water tank body 1.

[0042] One end of the piston 6 is connected to the first spring 5. Under the action of the pressure difference between the inside and outside of the water tank 1, the piston 6 moves axially along the connecting pipe 2, and drives the first spring 5 to extend and retract.

[0043] A water supply point is installed in the connecting pipe, when F 深埋水罐 +F 水 -F 浮＝ When M is reached, piston 6 moves axially along connecting pipe 2 to the water replenishment point and connects to water supply device 12 to automatically replenish water to the inner space of water tank 1.

[0044] In the formula: F 深埋水罐 To prevent the self-weight of the buoyancy-resistant deep-buried water tank, F 水 To resist the gravity of the water inside the floating, deeply buried water tank, F 浮 The buoyancy force borne by the anti-buoyancy deep-buried water tank is M, which is a constant and 0 ≤ M < F. 深埋水罐 .

[0045] Since the buoyant force on an object is equal to the weight of the liquid displaced by the object when it is in a stable state, when the water tank 1 is in its initial state, that is, when it is stably placed, the buoyant force on the anti-buoyancy deep-buried water tank is equal to the weight of the liquid displaced by the anti-buoyancy deep-buried water tank. Specifically, the anti-buoyancy deep-buried water tank resists the buoyant force by combining its own weight and the weight of the water inside the anti-buoyancy deep-buried water tank.

[0046] In a specific embodiment of the present invention, M is set to 0, that is, the buoyancy force F experienced by the anti-buoyancy deep-buried water tank is set to 0. 浮 Equal to the self-weight F of the anti-buoyancy deep-buried water tank 深埋水罐 When the water in the anti-buoyancy deep-buried water tank is under the weight of the water, the piston 6 moves axially along the connecting pipe 2 to the water replenishment point and automatically connects to the water supply device 12 to replenish the inner space of the water tank body 1.

[0047] The location of the water replenishment point depends on the size of the set M and the weight F of the anti-buoyancy deep-buried water tank. 深埋水罐 To determine, when F 深埋水罐 +F 水 -F 浮＝ When M is reached, piston 6 will move axially along connecting pipe 2 to the water replenishment point.

[0048] When M = 0, using the gravity calculation formula, we can conclude that:

[0049] ρ 水 gV 内 +F 深埋水罐＝ ρ 水 gV 排 ;

[0050] In the formula: ρ 水 Let g be the density of water, g be the acceleration due to gravity, and V be the acceleration due to gravity.内 V is the volume of water inside an anti-buoyancy deep-buried water tank. 排 The volume of water displaced by the anti-buoyancy deep-buried water tank.

[0051] Due to ρ 水 g, F 深埋水罐 All are fixed values, corresponding to V 排 With V 内 The difference is also fixed. Furthermore, according to the volume calculation formula, since V 排 With V 内 With the same bottom surface area, the water level inside the anti-buoyancy deep-buried water tank is 13 meters high (H). 内 The water level H of the anti-buoyancy deep-buried water tank. 排 That is, the water level in the outer space of the anti-buoyancy deep-buried water tank is 14 meters above the water level (H). 外 The difference is also a fixed value. Specifically, when M = 0, the height H of the water level 13 inside the anti-buoyancy deep-buried water tank is... 内 The water level 14 meters above the outer space of the anti-buoyancy deep-buried water tank. 外 The difference is due to the self-weight F of the anti-buoyancy deep-buried water tank. 深埋水罐 Caused by.

[0052] Furthermore, according to the pressure calculation formula, the external pressure on the piston 6 inside the connecting pipe 2 at the bottom of the water tank 1 is related to the height of the center position of the piston 6 from the water level 14 of the outer space of the anti-buoyancy deep-buried water tank, and the internal pressure on the piston 6 is related to the height of the center position of the piston 6 from the water level 13 of the inner space of the anti-buoyancy deep-buried water tank. However, due to the weight F of the anti-buoyancy deep-buried water tank... 深埋水罐 The resulting height H of the water level 13 inside the anti-buoyancy deep-buried water tank 内 The water level 14 meters above the outer space of the anti-buoyancy deep-buried water tank. 外 The difference is a fixed value, and the internal and external pressure difference at the center position of the piston 6 is also a fixed value. In a specific embodiment of the present invention, the internal pressure at the center position of the piston 6 and the elastic force of the first spring 5 are used to balance the external pressure at the center position of the piston 6. When the internal and external pressure difference at the center position of the piston 6 is a fixed value, the corresponding required elastic force of the first spring 5 is also fixed. According to the elastic force calculation formula, the corresponding required extension or contraction of the first spring 5 is also a fixed value. Thus, the relationship between the self-weight of the anti-buoyancy deep-buried water tank and the extension or contraction of the first spring 5 is established.

[0053] Because when F 深埋水罐 +F 水 -F 浮 When F = M, the extension or contraction of the first spring 5 under the action of the internal and external pressure difference is fixed. Correspondingly, the position of the piston after the first spring extends or contracts is fixed. Setting the position of the piston after the first spring extends or contracts as the water replenishment point can realize that when F 深埋水罐 +F水 -F 浮 When the value is M, the water supply device 12 is automatically connected to replenish the water inside the tank body 1.

[0054] One end of the first spring 5 is fixedly connected to the inner wall of the end of the connecting pipe 2 that connects to the inner space of the anti-buoyancy deep-buried water tank to form a first fixed end 4. The other end is fixedly connected to the piston 6 to form a movable free end. Under the action of the pressure difference between the inside and outside of the anti-buoyancy deep-buried water tank, the piston 6 moves axially along the connecting pipe 2 towards the inner space of the anti-buoyancy deep-buried water tank, thereby driving the free end of the first spring 5 to move together. The first spring 5 thus contracts. By setting a sensing or connecting device at the position after the piston moves a fixed distance with the free end of the first spring 5, it is possible to realize that when F 深埋水罐 +F 水 -F 浮 When M = , the piston 6 moves to the above position and triggers the sensing or connection device to realize automatic connection of the water supply device 12. The water supply device 12 is connected to the top of the water tank 1 through the water supply pipe 15, and water is replenished to the inside of the anti-floating deep buried water tank. The water replenishment point is the position corresponding to the piston after the free end of the first spring 5 retracts and moves a fixed distance.

[0055] When the sum of the spring force of the first spring 5 and the internal pressure at the center of the piston 6 is greater than the external pressure at the center of the piston 6, the first spring 5 pushes the piston 6 to move to the outer space of the anti-buoyancy deep-buried water tank and disconnects the connection with the water supply device 12, stopping the water replenishment work inside the anti-buoyancy deep-buried water tank. Thus, the automatic water replenishment work of the anti-buoyancy deep-buried water tank is realized.

[0056] In a specific embodiment of the present invention, one end of the first spring 5 is connected to the inner wall of the end of the connecting pipe 2 that connects to the outer space of the anti-buoyancy deep-buoyancy water tank to form a first fixed end 4. Under the action of the pressure difference between the inside and outside of the anti-buoyancy deep-buoyancy water tank, the piston 6 moves axially along the connecting pipe 2 toward the inner space of the anti-buoyancy deep-buoyancy water tank, thereby driving the free end of the first spring 5 to move together. The first spring 5 is thus extended. A sensing or connecting device is set at the position after the piston moves a fixed distance with the free end of the first spring 5. The water replenishment point is the position corresponding to the position after the piston moves a fixed distance with the free end of the first spring 5.

[0057] The anti-buoyancy device also includes a sliding screed 7 installed in the connecting pipe 2 and located between the piston 6 and the water supply point;

[0058] The end of the slider 7 away from the piston 6 is connected to a second spring 8. Under the action of the piston 6, the slider 7 moves axially along the connecting pipe 2 and compresses the second spring 8.

[0059] After the piston 6 drives the slide 7 to move axially along the connecting pipe 2 to the water replenishment point, the water supply device 12 is connected, and the water tank body 1 is automatically replenished with water.

[0060] Since piston 6 needs to move repeatedly in connecting pipe 2, resulting in significant wear, a sliding indicator 7 is separately installed at the top of connecting pipe 2 and electrically connected to water supply device 12 to facilitate subsequent replacement.

[0061] In a specific embodiment of the present invention, the elastic forces of the second spring 8 and the first spring 5, together with the internal pressure at the center of the piston 6, balance the external pressure at the center of the piston 6. Specifically, one end of the second spring 8 is connected to the inner wall of the end of the connecting pipe 2 that connects to the inner space of the anti-buoyancy deep-buried water tank to form a second fixed end 9, and the other end is connected to the end of the slider 7 away from the piston 6 to form a free end. When the piston 6 moves a certain distance along the axial direction of the connecting pipe 2 towards the inner side of the anti-buoyancy deep-buried water tank under the action of the pressure difference between the inside and outside of the anti-buoyancy deep-buried water tank, the piston 6 drives the slider 7 set on the top of the connecting pipe 2 to move together by magnetic force or pushing, and compresses the second spring 8 until the slider 7 moves to the position of the piston 6. After the water point is reached, the sensing or connection device is triggered to automatically connect the water supply device 12 and start replenishing water to the inside of the anti-floating deep-buried water tank. When the sum of the elastic force of the second spring 8, the first spring 5 and the internal pressure at the center of the piston 6 is greater than the external pressure at the center of the piston 6, the first spring 5 pushes the piston 6 to move to the outer space of the anti-floating deep-buried water tank, the second spring 8 pushes the slider 7 to move to the outer space of the anti-floating deep-buried water tank, and disconnects the connection with the water supply device 12, stopping the water replenishment work inside the anti-floating deep-buried water tank.

[0062] To maintain the stability of the anti-buoyancy deep-buried water tank, one end of the connecting pipe 2 is set on the bottom side wall of the water tank body 1, connecting with the inner space of the water tank body 1, and the other end extends horizontally to the outside of the water tank body 1, connecting with the outer space of the water tank body 1, so as to increase the bottom surface area of ​​the anti-buoyancy deep-buried water tank.

[0063] Alternatively, one end of the connecting pipe 2 can be set on the bottom side wall of the water tank body 1, connecting with the outer space of the water tank body 1, and the other end can be extended horizontally to the inner side of the water tank body 1, connecting with the inner space of the water tank body 1, so as to reduce the area occupied by the anti-buoyancy deep buried water tank and make it suitable for use in narrow spaces.

[0064] To further enhance the stability of the anti-buoyancy deep-buried water tank and to avoid excessive extension or contraction of a single first spring 5, which would affect the smooth operation of the anti-buoyancy device, multiple connecting pipes 2 are distributed around the bottom of the water tank body 1. Each connecting pipe 2 is equipped with a piston 6 and a first spring 5.

[0065] In a specific embodiment of the present invention, four connecting pipes 2 of the same length are symmetrically distributed around the bottom of the water tank body 1. Each connecting pipe 2 is equipped with a piston 6 and a first spring 5 in the same manner. When a pressure difference is generated between the inner space and the outer space of the anti-buoyancy deep-buried water tank, the pistons 6 in the four connecting pipes 2 move together along the axial direction of the corresponding connecting pipe 2, and drive the corresponding first piston 6 to extend or retract, so as to balance the pressure on the outside of the anti-buoyancy deep-buried water tank.

[0066] In other embodiments of the present invention, four connecting pipes 2 are distributed circumferentially along the bottom of the water tank body 1. The length of the four connecting pipes 2 is specifically set according to the size of the space where the anti-buoyancy deep-buried water tank is located, and the circumferential distribution position of the four connecting pipes 2 is specifically adjusted according to their respective lengths to achieve stable placement of the anti-buoyancy deep-buried water tank.

[0067] A baffle 3 is provided at one end of the connecting pipe 2 that connects to the outer space of the water tank body 1 to prevent the piston 6 from falling out of the connecting pipe 2.

[0068] In other embodiments of the present invention, there are two baffles 3, which are centrally symmetrically distributed at one end of the connecting pipe 2 and the outer space of the water tank body 1, so as to jointly block the piston 6 and prevent it from falling off.

[0069] The slider 7 is a Z-shaped structure formed by the staggered connection of the upper slider and the lower slider. The top of the connecting pipe 2 is axially provided with an opening structure 16. The lower surface of the upper slider is pressed against the upper surface of the top of the connecting pipe 2 near the opening structure 16. The lower surface of the top of the connecting pipe 2 near the opening structure 16 is pressed against the upper surface of the lower slider. The slider 7 is moved and locked in the opening structure 16.

[0070] The end of the lower slider away from the piston 6 is connected to the second spring 8;

[0071] After piston 6 pushes the lower slider until the upper slider moves to the water replenishment point, the water supply device 12 automatically connects to replenish the water tank 1's inner space.

[0072] In a specific embodiment of the present invention, the upper slider and the lower slider are connected at their adjacent ends in an alternating manner to form a staggered platform, as shown in the attached figure. Figure 1As shown, the upper slider is located on the right side of the opening structure 16, and the lower surface of the upper slider is pressed against the upper surface of the connecting pipe 2 near the right side of the opening structure 16. The lower slider is located on the left side of the opening structure 16, and the lower surface of the connecting pipe 2 near the left side of the opening structure 16 is pressed against the upper surface of the lower slider. Specifically, the axial length of the upper slider and the lower slider along the connecting pipe 2 is greater than the axial length of the opening structure 16 along the connecting pipe 2. The upper and lower staggered connection points of the upper slider and the lower slider are located in the opening structure 16 and can move along the axial direction of the connecting pipe 2. During the axial movement of the slider, it always covers the opening structure 16 to prevent the inner and outer sides of the anti-buoyancy deep buried water tank from communicating at the opening structure 16. Thus, the slider 7 is moved and locked in the opening structure 16.

[0073] One end of the second spring 8 is connected to the inner wall of the end of the connecting pipe 2 that connects to the inner space of the anti-buoyancy deep-buried water tank to form a second fixed end 9, and the other end is connected to the left end of the lower slider to form a free end. When the piston 6 moves a distance into the anti-buoyancy deep-buried water tank under the action of the pressure difference between the inside and outside of the anti-buoyancy deep-buried water tank, the piston 6 abuts against the right end of the lower slider and continues to push the slider as a whole to move into the anti-buoyancy deep-buried water tank. When the upper slider moves to the water replenishment point, it triggers the sensing or connecting device set at the water replenishment point to realize the automatic connection of the water supply device 12 and start replenishing water into the inside of the anti-buoyancy deep-buried water tank.

[0074] In other embodiments of the present invention, one end of the second spring 8 is connected to the outer wall of the end of the connecting pipe 2 that connects to the inner space of the anti-buoyancy deep-buried water tank to form a second fixed end 9, and the other end is connected to the left end of the upper slider to form a free end.

[0075] A connector is installed at the water supply point, one end of which is electrically connected to the water supply device 12. A receiver is installed in the upper slider, one end of which is electrically connected to the water supply device 12.

[0076] When piston 6 pushes the lower slider until the upper slider moves to the water replenishment point, the receiver and connector are connected to form a closed circuit, and the water supply device 12 replenishes water to the inner space of the water tank 1.

[0077] In a specific embodiment of the present invention, one end of the connector is electrically connected to the water supply device 12 via the second wire 11, and one end of the receiver is electrically connected to the water supply device 12 via the first wire 10. The receiver set in the upper slider and the connector set at the water replenishment point are wet pluggable connectors, which have good waterproof performance and can realize live pluggable connection operations in water.

[0078] To ensure stable insertion and removal of the connector and receiver while maintaining connection stability, the connector is fixedly installed at the water inlet point at the top of the connecting pipe 2.

[0079] A water level sensor is installed at the bottom of the water tank 1 to monitor the water level in the inner and outer spaces of the water tank 1, and transmits the monitored information to the control center in real time.

[0080] In a specific implementation of the present invention, two water level sensors are installed, located on the inner and outer walls of the bottom of the water tank body 1, respectively. On the one hand, they can monitor the water level 13 in the inner space of the anti-buoyancy deep-buried water tank and the water level 14 in the outer space of the anti-buoyancy deep-buried water tank in real time, and determine whether the anti-buoyancy device is working properly. On the other hand, when the water level 13 in the inner space of the anti-buoyancy deep-buried water tank rises to the top of the water tank body 1, the water level sensor sends an alarm signal to the control center to remind the staff to take appropriate drainage measures.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
