Description
P/00/01I Regulation 3.2 AUSTRALIA Patents Act 1990 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title: "POTENTIAL ENERGY REGENERATING SYSTEM AND METHOD AND ELECTRICITY REGENERATING SYSTEM AND METHOD" The following statement is a full description of this invention, including the best method of performing it known to me/us: PAT1794/B POTENTIAL ENERGY REGENERATING SYSTEM AND METHOD AND ELECTRICITY REGENERATING SYSTEM AND METHOD BACKGROUND OF THE INVENITON 5 Field of the Invention The present invention relates to a potential energy regenerating system and method and an electricity regenerating system and method. Particularly, the potential 10 energy regenerating system and method relates to a system and method capable of generating and increasing a liquid' s potential energy by repeatedly using a liquid and having the gravitation as its energy source, and the electricity regenerating system and method relates to a system and method 15 for regenerating electricity by using a liquid-level difference generated by foregoing potential energy regenerating system. Description of the Related Art 20 For a long time, Pascal's principle is used to lift up a large piston with a small piston. On an application of a hydraulic lift, as long as a smaller push-down force is applied on the small piston, a larger lift-up force will then be generated on the large piston. 25 However, it is easy to neglect that Pascal' s principle can be used to increase an incompressible liquid' s potential PAT 1794/B energy by universal gravitation. Fig. 1 is a schematic view of a hydraulic lift, wherein the area of a large piston is A,, and the area of a small piston is A 2 . If a push-down force F, is exerted on the large piston, 5 a lift-up force F 2 will then be generated on the small piston, and Fi/Ai=F2/A2 (1) Aid 1

An Equation (3) can be derived from Equations (1) and (2) as follows: d2= (A1/A2) di (3) Equation (3) shows that the displacement of the small piston is equal to the area ratio of the large piston to the 15 small piston multiplied by the displacement of the large piston. For example, if Ai=1m 2 , A 2 =100cm 2 , dl=lm, then
(A

2 ) d 1 = (1m 2 /100cm 2 ) xlm =(10000cm 2 /100cm 2 ) xlm =loom 20 That is, a force is exerted downwards on the large piston to move it down lm. Under this case, a lift-up force is generated on the small piston to move it up loom. For a long time, using a large piston to lift up a small piston does not meet economic efficiency, so such an 25 application is seldom put into practice. Fig. 2 is a schematic view showing that a hydraulic 2 PAT 1794/B compressor transmits a liquid using Pascal' s principle. A mass T having M Kgw is placed on the large piston. Due to gravity, a constant push-down force F 1 =Mg is exerted on the large piston, wherein g is acceleration of gravity (=9.8m/s 2 ) 5 Furthermore, a lift-up force F 2 will be generated on the small piston. When the small piston is lifted up to a height of h meters, the hydraulic lift is no longer in an enclosed state, but an opening on a pipe wall where the small piston is located is provided to direct the liquid to a liquid tank. 10 As shown in Fig. 2, it is assumed that the liquid stored is pure water, and the area of the large piston A 1 =1m2, the area of the small piston A 2 =10cm 2 =0.001m 2 . Now, a push-down force is exerted on the large piston to move it down by 1m. According to Pascal' s principle, a lift-up 15 force can be generated on the small piston to move it up by 1000 meters. It is assumed that an opening is provided on a pipe wall located at a height of 100m in the pipe line where the small piston is located, and the opening is horizontally connected 20 to a storage container (base area: 1m 2 , height: 1m)through a pipe line. It is assumed that a counterweight having 10OKgw is placed on the large piston, and no object is put on the small piston. The counterweight exerts a force downwards on the large piston 25 due to gravity. When the large piston is moved down by 1m, liquid of 0. 9m 3 out from pure water of 1m 3 below the large piston 3 PAT1794/B is squeezed into the liquid storage container having a height of 100m. Another water of 0.1m 3 will remain at the bottom of the pipe line where the small piston is located. The change of potential energy of the entire system is as follows: 5 (1) When the counterweight moves down by 1m, the potential energy thereof reduced is: mgh=100xgxl=lOOx9.8x1=980(joules). (2) Considering that water of 0. 9m 3 is moved into the liquid storage container at a height of 100m, the potential energy 10 thereof increased is: mgh=(0.9x1,000)x9.8x100 =882,000(joules). (3) Another water of O.1m 3 will remain at the bottom of the pipe line where the small piston is located. A simple 15 method for calculating the increased potential energy is to consider the entire weight to be concentrated at one point and thus, at its center of gravity. That is, it is concentrated at a height of 50m. So, the potential energy thereof increased is: 20 mgh=(0.lxl,000)x9.8x50=49,000(joules). (4) The change of potential energy of the entire system is the increment of potential energy of water minus the decrement of potential energy of the counterweight, shown as: 88 2 ,000+49,000-980=930,020(joules). 25 By observing the changes of potential energies in items (1) , (2) , and (3) , it is found that with the modified structure 4 PAT I 794/B of the hydraulic compressor and appropriate universal gravitation , the liquid can be moved up to the higher storage container and thus, the potential energy of the liquid is increased. 5 Although in Fig. 2, universal gravitation is used to transmit the liquid up to the higher storage container, there exists a considerable disadvantage. That is, when a liquid storage bag is filled with the liquid, it is quite easy to create more liquid' s potential energy; however, it requires 10 significant energy consumed to re-fill the liquid storage bag with the liquid. Consequently, it is not economic to use this structure to create the potential energy. In view of the above disadvantage of the prior art, the present invention herein provides a potential energy 15 regenerating system and method and an electricity regenerating system and method, wherein a compressible liquid bag is squeezed by appropriately directed universal gravitation, so that a liquid stored in a bag can be transmitted to a storage tank having a higher potential energy. 20 SUMMARY OF THE INVENTION A main objective of the present invention is to provide a vertical-type liquid potential energy regenerating system, comprising: 25 a liquid storage bag module, including a compressible liquid storage bag device having a compressible liquid storage 5 PAT 1794/B bag, a bottom of the compressible liquid storage bag being provided with an access opening, the compressible liquid storage bag device being in a vertical type; a pipe line module, including a liquid access opening 5 switch control device and a pipe line, one end of the liquid access opening switch control device having an access opening, the other end having two access openings, the liquid access opening switch control device being higher than the highest level that the compressible liquid storage bag can reach, the 10 pipe line being in a U-shape and extending upwards to be connected with the liquid access opening switch control device; a liquid storage tank module, including a liquid storage tank with a bottom higher than the highest position that the 15 compressible liquid storage bag can reach, the liquid storage tank having a pipe line connected to the liquid access opening switch control device; and a squeezing weight module, including a squeezing weight mass and a control device, wherein the squeezing weight mass 20 is placed on a top of the compressible liquid storage bag, and the control device allows the squeezing weight mass to be lifted and released. The liquid is stored in a liquid storage bag which is compressible and has an access opening. Then, the 25 compressible liquid storage bag is placed in a hydraulic compressor frame, from which its internal structure is 6 PAT1794/B detached. The purpose to put the compressible liquid storage bag in the container is that when the compressible liquid storage bag is squeezed, the compressible liquid storage bag can have a support to transmit the liquid in the bag to a liquid 5 storage tank at a higher level. A squeezing weight mass used to squeeze the liquid storage bag is separated from the liquid storage bag. When the squeezing weight mass is released, the liquid storage bag is squeezed; and when the squeezing weight mass is lifted up the liquid flows into the liquid storage 10 bag again due to the gravity of the liquid. The access opening of the liquid storage bag is controlled by the liquid access opening control device. The liquid access opening control device may be a mechanical device or be one controlled by a microcomputer, and has a function to control the liquid access 15 opening to allow the liquid to flow in one way(Fig. 8 shows an embodiment). The advantage of the present invention is that the squeezing weight mass and the liquid storage bag are separated. Therefore, it only consumes a little energy to lift up the 20 squeezing weight mass. Then, the liquid storage bag is filled with the liquid again due to the gravity of the liquid. Next, the gravity of the squeezing weight mass is used to transmit the liquid to the storage tank at a higher level, so that the potential energy of the liquid can be increased. 25 Another objective of the present invention is to provide a vertical-type liquid potential energy regenerating method, 7 PAT 1794/B which is applied to a vertical-type liquid potential energy regenerating system, the method comprising the steps of: lifting up a squeezing weight mass and locating the squeezing weight mass at a position above a liquid storage bag where 5 the liquid storage bag can reach; making a liquid flow into the liquid storage bag through an access opening of the liquid storage bag, until the liquid storage bag is filled with the fluid or no more fluid flows into the liquid storage bag; and releasing the squeezing weight mass to make it squeeze the 10 liquid storage bag. The foregoing potential energy regenerating system squeezes the liquid storage bag with a freely falling body to increase the potential energy of the liquid. Furthermore, in another embodiment of the present invention which will be 15 described later, a container receiving the liquid storage bag is obliquely placed on a support plate. Then, the squeezing weight mass slides or rolls due to gravity, so as to convert gravity into potential energy. Another objective of the present invention is to provide 20 an inclined-type liquid potential energy regenerating system, comprising: a liquid storage bag module, including a compressible liquid storage bag device having a compressible liquid storage bag, a bottom of the compressible liquid storage bag being 25 provided with an access opening; an inclined plate module, including a rectangular inclined 8 PAT 1794/B plate inclined by an appropriate angle with respect to the horizontal ground, the compressible liquid storage bag being obliquely placed on the rectangular inclined plate, and the access opening of the compressible liquid storage bag being 5 adjacent to both ends of the rectangular inclined plate; a pipe line module, including a liquid access opening switch control device and a pipe line, one end of the liquid access opening switch control device having an access opening, the other end having two access openings, the liquid access 10 opening switch control device being higher than the highest level that the compressible liquid storage bag can reach, one end of the pipe line connected to the access opening at the bottom of the compressible liquid storage bag, the pip line being in a U-shape and extending upwards to be connected with 15 the liquid access opening switch control device; a liquid storage tank module, including a liquid storage tank with a bottom higher than the highest level that the compressible liquid storage bag can reach, the liquid storage tank having a pipe line which connects the outlet of the 20 compressible liquid storage bag to the inlet of the liquid storage tank; and a squeezing weight module, including a squeezing weight mass and a control device, wherein the squeezing weight mass is placed on the rectangular inclined plate and located above 25 the compressible liquid storage bag, and the control device allows the squeezing weight mass to be lifted and released. 9 PAT 1794/B A further objective of the present invention is to provide an inclined- type liquid potential energy regenerating method, which is applied to an inclined-type liquid potential energy regenerating system, the method comprising the steps of: 5 lifting a squeezing weight mass and locating the squeezing weight mass on a top of the inclined plate where a liquid storage bag can reach; making liquid flow into the compressible liquid storage bag through an access opening of the compressible liquid storage bag until the compressible 10 liquid storage bag is filled with the fluid or no more fluid flows into the compressible liquid storage bag; and releasing the squeezing weight mass. The foregoing inclined-type liquid potential regenerating system squeezes the liquid storage bag in a sliding (or rolling) 15 manner to transmit the liquid to a higher position. Two identical inclined-type liquid potential energy regenerating systems are combined in symmetry to form a system having a seesaw structure. Since the left and right sides of the seesaw structure are symmetric and are independent 20 inclined-type gravity to potential energy conversion systems, liquid in the liquid storage bags can be transmitted to the above liquid storage tank through the compressible liquid storage bags and the squeezing weight devices on the seesaw. Therefore, to make it becomes a potential energy regenerating 25 system as long as the outlets of the above liquid storage tank have to be appropriately controlled so that the liquid in the 10 PAT 1 794/B liquid storage tank can alternately flow into the liquid storage bags on the right and left sides, resulting in an imbalance of torque to make the seesaw incline to one side. Using this simple technique, the right and left sides of the 5 seesaw will alternately swing up and down, thus forming a potential energy regenerating system. Another objective of the present invention is to provide a seesaw-type potential energy regenerating system, comprising: 10 a seesaw module, comprising a rectangular smooth plate, a center of which is placed on a base, so that both ends of the smooth plate can swing up and down, a partition device being provided on the center of the smooth plate for partitioning the smooth plate into two sides, each side of 15 the smooth plate being provided with a baffle plate perpendicular to the smooth plate for stopping a mass sliding down along the smooth plate, the baf f le plate having an opening through which a pipe line can pass; two liquid storage bag modules, each comprising a 20 compressible liquid storage bag, placed on both sides of the plate of the seesaw module, respectively, a bottom of each compressible liquid storage bag having an access opening and fixed on a flat plate; a liquid storage tank module, comprising a liquid storage 25 tank with bottom higher than a liquid access opening switch control device, the liquid storage tank having an inlet and 11 PATI794/B having two outlets at the bottom of the liquid storage tank, each having a pipe line, the two outlets being connected to the liquid input pipe lines of the liquid storage bags on the right and left sides, respectively, each of the outlets being 5 provided with a plug connected to a control rope, for controlling the outlets to be open or closed, an outlet control rope connected to the liquid input pipe line of the right compressible liquid storage bag being connected to the left squeezing weight mass of the seesaw module, an outlet control 10 rope connected to the liquid input pipe line of the left compressible liquid storage bag being connected to the right squeezing weight mass of the seesaw module, the plug having an appropriate weight, wherein when a control rope is released, a corresponding plug falls down to close a corresponding 15 outlet, and when a control rope is pulled, a corresponded outlet is opened; and the liquid access opening switch control device, one end of which is connected to the access opening of the compressible liquid storage bag, the other end of which has two openings, 20 wherein one opening is connected to the inlet of the liquid storage tank, and the other opening is connected to a corresponding outlet of the liquid storage tank, the liquid access opening switch control device allowing liquid to flow in one way. 25 By the inclined-type potential energy regenerating systems having a seesaw structure and formed by symmetry 12 PAT 1794/B combination, a potential energy regenerating system is constructed. This potential energy regenerating system is a device having a seesaw structure which can swing up and down in turn between the right and left sides. 5 A further objective of the present invention is to provide a method of starting a potential energy regenerating system, comprising the steps of: making the potential energy regenerating system be in a state that no liquid is contained; 10 using an external force to support the smooth plate of the seesaw module to be in a horizontal state, making the squeezing weight masses on both sides of the smooth plate of the seesaw module be biased to the center of the smooth plate, so that the plugs connected to the control ropes all block their 15 corresponding outlets; inputting an adequate amount of liquid from the inlet of the liquid storage tank; and removing the external force for support so that the torque on the smooth plate is in an imbalance state, and one of the 20 control ropes opens a corresponding outlet to start the potential energy regenerating system. The above potential energy regenerating system generates a liquid circulating system having a liquid-level difference. A liquid in a first compressible liquid storage bag is squeezed 25 by a corresponding squeezing weight mass (the squeezing weight mass moves down due to universal gravitation) to 13 PAT 1794/B transmit the liquid in the bag to a liquid storage tank at a higher level. When the squeezing weight mass stops squeezing the bag, a corresponding outlet at the bottom of the liquid storage tank at a higher level is opened. Therefore, 5 the liquid in the liquid storage tank starts to flow into a second compressible liquid storage bag on the other side of the smooth plate (seesaw) . When sufficient liquid flows into the second compressible liquid storage bag, an imbalanced torque is created. This imbalanced torque further causes the 10 seesaw to incline to one side. The liquid in the second compressible liquid storage bag is squeezed again to transmit the liquid in the storage bag to the above high-level liquid storage tank. Then, the other outlet of the above liquid storage tank is opened, and the liquid flows into the first 15 liquid storage bag. Next, an imbalanced torque is further created. This causes the seesaw to further incline to the other side. Then, the first liquid storage bad is squeezed again. By repeating these steps, a liquid circulating system is formed. Fig. 6 is a schematic view showing the liquid 20 circulating system having a liquid-level difference. Another objective of the present invention is to provide a liquid circulating system having a liquid-level dif ference. This circulating system is made of a potential energy regeneration system. This circulating system comprises: 25 a liquid storage tank; two compressible liquid storage bags, disposed on left and 14 PAT 1794/B right sides respectively; and pipe lines, connecting the liquid storage tank to the compressible liquid storage bags, respectively, wherein a process for circulating liquid under a liquid-level 5 difference comprises: allowing the liquid to flow from the above liquid storage tank to the right liquid storage bag; allowing the liquid to flow from the right liquid storage bag to the above liquid storage tank; allowing the liquid to flow from the above liquid storage tank to the left liquid storage 10 bag; and allowing the liquid to flow from the left liquid storage bag to the above liquid storage tank. The foregoing potential energy regenerating system can create a system for circulating liquid under a liquid-level difference. This system for circulating liquid under a 15 liquid-level difference has a characteristic of different liquid-level. Therefore, it only needs to put a water turbine in an appropriate position of the system for circulating liquid under a liquid-level difference, then the electricity will be generated using the liquid-level difference. 20 Between a first liquid storage tank and the liquid storage bags of the individual potential energy regenerating system, a liquid storage tank is provided and referred to as a second liquid storage tank. The second liquid storage tank is lower than the first liquid storage, but higher than liquid storage 25 bags of the individual potential energy regenerating system. In hydroelectric power generation, the liquid-level 15 PAT1794/B difference between the first and the second liquid storage tanks is used to generate electricity. A hydroelectric generator is placed under the first liquid storage tank, and the outlet of the hydroelectric generator is higher than the 5 inlet of the second liquid storage tank. The liquid flowing through the hydroelectric generator collectively flows into the second liquid storage tank, and then flows into the individual potential energy regenerating system from the outlets, respectively. 10 Moreover, a potential energy regenerating system array formed of a plurality of potential energy regenerating systems is used, and a plurality of liquid storage tanks is combined into a larger liquid storage tank (referred to as a f irst liquid storage tank, and also referred to as a highest-level liquid 15 storage tank). It has a highest liquid potential energy for creating a larger amount of water, and this larger amount of water is used to generate a larger volume of electricity. A further objective of the present invention is to provide an electricity regenerating system, comprising: a first 20 liquid storage tank, having an inlet and an outlet; a second liquid storage tank, wherein the first liquid storage tank is higher than the second liquid storage tank, and the second storage tank is provided with an inlet and a plurality of outlets; a water turbine generator set, generating 25 electricity by using the liquid-level difference between the first liquid storage tank and the second liquid storage tank; 16 PAT 1794/B a seesaw module array, comprising a plurality of seesaw modules, each of the seesaw modules comprising a rectangular smooth plate, wherein the center of the smooth plate is placed on a base to make both ends of the smooth plate swing up and 5 down; a partition device being provided on the center of the smooth plate for partitioning the smooth plate into two sides and for preventing masses disposed on the smooth plate from sliding from one side to the other side when the smooth plate swings up and down; each side of the smooth plate being provided 10 with a baffle plate perpendicular to the smooth plate for stopping a mass sliding down along the smooth plate; each of the seesaw modules including two liquid storage bag modules; each of the liquid storage bag modules including a compressible liquid storage bag placed on each side of the 15 smooth plate, respectively; the bottom of each compressible liquid storage bag having an access opening; the bottom of the compressible liquid storage bag being fixed on a flat plate; each of the compressible liquid storage bags being lower than the second liquid tank; each of the liquid storage bag modules 20 including a pipe line, one end of which is connected to the access opening of the compressible liquid storage bag and the other end of which branches into two pipe line openings, wherein one opening serves as an input pipe line of the compressible liquid storage bag and is connected to an outlet 25 of the second liquid tank, and the other opening serves as an output pipe line of the compressible liquid storage bag 17 PAT 1794/B and is connected to the inlet of the first liquid storage tank; the openings of the pipe lines allowing the liquid to flow in one way; an access opening control unit, for controlling all the outlets at the bottom of the second liquid storage 5 tank to be open or closed, so that the compressible liquid storage bags are alternately fed with liquid to achieve a potential energy system. Another objective of the present invention is to provide an electricity regenerating method using the above 10 electricity regenerating system, comprising the steps of: making the electricity regenerating system be in a state that no liquid is contained; using an external force to support the seesaw modules of the electricity regenerating system all in a horizontal state; 15 making the squeezing weight masses on both sides of each seesaw module be biased to the center of the smooth plate of each seesaw module, wherein all the outlets at the bottom of the second liquid storage tank are in a closed state; inputting an adequate amount of liquid from the inlet of 20 the first liquid storage tank; removing the external force for support so that the torque on the smooth plate of each seesaw module becomes imbalanced, and the smooth plate of each seesaw module is inclined to one side; and 25 opening an outlet at the bottom of the compressible liquid storage bag which is in a higher level and is connected to 18 PATIO 794/B the second liquid storage tank, so as to start to input the liquid to one of the liquid storage bags. In summary, the present invention discloses a potential energy regenerating system which is constructed by using a 5 simple seesaw structure in cooperation with Pascal' s principle and continuous action of universal gravitation. Although the function of this potential energy regenerating system is limited, a liquid circulating system having a liquid-level difference created by the potential energy 10 regenerating system is a regeneration energy source which can be completely controlled and used. An electricity regenerating system uses this liquid circulating system having a liquid-level difference to generate electricity. 15 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing a hydraulic lift, wherein a small piston is lifted up with a large piston nontraditionally.

Fig. 8c illustrates that the compressible liquid access opening switch control device allows the fluid to flow into the compressible liquid storage bag. 20 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of each system according to the present invention will be described with reference to the drawings, wherein the same element is 25 designated with the same reference numeral. Please referring to Fig. 3, a liquid potential energy 20 PAT1794/B regenerating system of a preferred embodiment of the present invention is shown. The system comprises: a liquid storage bag module 310, a pipe line module 320, a liquid storage tank module 330, and a squeezing weight module 340. A compressible 5 liquid storage bag 3101 is placed in a hollow container 3104. The top 3102 of the liquid storage bag is shaped into a flat form so as to increase contact area for compression. An access opening 3103 having a smaller diameter is provided at the bottom of the liquid storage bag and connected to a pine line 10 which is bent upward and extends to a level higher than the top of the liquid storage bag and then connected to a liquid access opening switch control device 3201. The liquid access opening switch control device 3201 is provided with two openings, one for a pipe line extending upwards and the other 15 for a branch, the two openings being the outlet and inlet of the liquid storage bag, respectively, wherein an opening 3203 is connected to the pipe line extending to the inlet of the liquid storage tank 3301 having a much higher level, and the other opening for a branch is connected to the inlet 3202 of 20 the compressible liquid storage bag 3101. In the preferred embodiment of the present invention, the liquid access opening switch control device 3201 is a mechanism for one-way flow. For the inlet 3202, when a liquid is not inputted to the liquid storage bag, the inlet 3202 is 25 in a closed state automatically; when a liquid having a higher potential energy flows into the inlet 3202, the weight of the 21 PAT I794/B liquid makes the inlet 3202 open and the outlet 3203 is in a closed state; at this time, the liquid flows into the liquid storage bag only from the inlet 3202 but not from the outlet 3203. For the outlet 3203, when the liquid storage bag is 5 squeezed, the inlet 3202 is in a closed state and thus, a fluid flows out upwards only from the outlet 3203 but not from the inlet 3202. An important feature of the present invention is that the liquid cannot flow in and out of the liquid storage bag at the same time. 10 The liquid stored in the compressible liquid storage bag and the liquid storage tank is incompressible. The compressible liquid storage bag is placed in a hollow container, a bottom of the container has an opening, and when 15 the compressible liquid storage bag is squeezed, a wall of the hollow container provides a necessary reaction force. In the preferred embodiment of the present invention, a process for operating the system comprises the steps of: (1) keeping the liquid storage bag 3101 in an empty state 20 at first; (2) lifting and stopping a squeezing weight mass 3401 on the top where the liquid storage bag 3101 can reach; (3)allowing liquid at a level higher than the inlet 3202 to flow into the liquid storage bag 3101 through this inlet 25 3202 by using its own weight until the liquid storage bag is filled with the liquid or no more liquid flows into the liquid storage bag; (4) releasing the squeezing weight mass 3401 to squeeze the 22 PAT 1794/B liquid storage bag 3101 , so that the liquid in the liquid storage bag is transmitted to the liquid storage tank 3301 at a higher level; and (5) repeating the steps (1)-(4). 5 In the above vertical-type liquid potential energy regenerating system, the liquid access opening switch control device plays a quite important role. It allows the liquid to flow into the compressible liquid storage bag and allows the liquid in the bag to be transmitted to the above liquid storage 10 tank by using very little energy. Fig. 8a shows a liquid access opening access opening switch control device of a preferred embodiment of the present invention. The device comprises a vertical pipe line and a branch pipe line extending and bent upwards, wherein g is 15 acceleration of gravity (=9.8m/s 2 ) with a downward direction. The upward pipe line has a cover plate inside, which can be swung up; when the liquid flows upward, the cover plate is swung up under a force, and then a pipe line channel is opened; when no liquid flows upward, the pipe line channel is closed 20 due to the cover plate' s own weight.
