Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a thermal compensator suitable for pipelines. Background Art

[0002] Thermal compensators, also known as expansion joints or telescopic joints, are widely used in industries such as petroleum and heating. In particular, thermal compensators are installed on heating pipelines to prevent deformation or damage caused by thermal elongation or temperature stress when the pipeline heats up. This compensates for the thermal expansion of the pipeline, thereby reducing stress on the pipe wall and the forces acting on valve components and support structures.

[0003] Common thermal compensators currently available on the market include bellows, square compensators, sleeve compensators, and spherical compensators. Sleeve compensators, with their advantages of high compensation capacity, small footprint, low flow resistance, and relatively low cost, have been widely used in thermal piping systems. They effectively absorb the expansion and contraction deformation of pipes caused by temperature fluctuations, ensuring the stability and safety of the piping system.

[0004] Sleeve compensators consist of a sleeve tube sealed with packing and an outer shell tube. The packing inside the compensator gradually wears over time. When this wear reaches a certain level, leakage can occur between the sleeve tube and the outer shell tube. However, since leaks are relatively hidden, they are difficult to detect when they occur. This can lead to the loss of resources such as hot water within the pipeline, resulting in waste and potentially endangering personnel safety. Utility Model Content

[0005] The purpose of the present utility model is to provide a thermal compensator suitable for a pipeline to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A thermal compensator suitable for a pipeline, comprising:

[0008] The compensator body has an annular protective shell fixedly connected to the outside of the compensator body, a platform fixedly connected to the protective shell, a through slot provided on the outside of the protective shell, a first shell provided on the side of the protective shell close to the through slot, the first shell being threadedly connected to the protective shell, a second shell fixedly connected to one side of the first shell, an alarm button provided in the first shell, a buzzer provided in the second shell, and a rubber ring fixedly connected to the protective shell;

[0009] A detection component is located in the first housing and is used to detect whether the compensator body is leaking;

[0010] A pop-up component is located in the second housing and is used to control the position of the buzzer;

[0011] The blocking component is located inside the protective shell and is used to block the place where leakage occurs in the compensator body.

[0012] When the gap between the sleeve and the outer sleeve of the compensator body (the compensator body refers to the sleeve compensator, which is a mature technology in the existing technology and will not be described in detail) leaks (such as point A in the figure), the leaked hot water will leak into the protective shell through the gap. The rubber ring inside the protective shell can ensure the sealing of the protective shell. At this time, the hot water will quickly fill the protective shell and squeeze the detection component. After the detection component detects the pressure, it will press the alarm button. At this time, the alarm button will transmit a signal to the external controller. At the same time, the detection component also controls the pop-up component to work, so that the buzzer pops up. The external controller controls the blocking component and the buzzer to work, and at the same time, the alarm signal is transmitted to notify the staff to carry out maintenance. The external controller controls the buzzer to work in order to warn and drive away the surrounding personnel, thereby protecting the personnel's safety. The controller controls the blocking component to work in order to block the leaking gap to prevent continuous leakage, thereby reducing the waste of resources. By providing the blocking component, the detection component and the pop-up component to work together, the leak can be detected and stopped at the first time it occurs, thereby avoiding the waste of resources and protecting the safety of personnel.

[0013] A further improvement of the technical solution of the present utility model is that the detection component includes a base plate, the base plate is slidably connected to the first shell, a pressure spring is fixedly connected to one side of the base plate, the other end of the pressure spring is fixedly connected to the first shell, and the end of the base plate close to the pressure spring is fixedly connected to the first push rod.

[0014] The above-mentioned technical solution is adopted. In this solution, when the hot water in the pipe leaks, the hot water will fill the protective shell and squeeze the bottom plate due to its own gravity and the pressure in the pipe. At this time, the bottom plate moves downward and squeezes the pressure spring. At this time, the pressure spring is in a compressed state. The bottom plate will continue to move downward and squeeze the alarm button through the first push rod fixedly connected below it, thereby controlling the blocking component and the buzzer to work through the external controller, thereby achieving the purpose of detection.

[0015] A further improvement of the technical solution of the present utility model is that: the detection component also includes a heat conducting plate, which is fixedly connected to the side of the base plate away from the pressure spring, a second push rod with a T-shaped arrangement is slidably connected in the first push rod, one side of the second push rod is fixedly connected to an elastic spring, the other end of the elastic spring is fixedly connected to the first push rod, an expansion block is provided between the second push rod and the heat conducting plate, and the two ends of the expansion block respectively conflict with the heat conducting plate and the second push rod.

[0016] The above technical solution is adopted. In this solution, when the speed of the leaking hot water is not very fast, it takes a certain amount of time to press the alarm button. At this time, the hot water will flow through the protective shell into the first shell at the bottom. At this time, the bottom plate will move downward but will not touch the alarm button. By providing a heat conducting plate at the end of the bottom plate away from the pressure spring, the heat of the hot water will be transferred to the expansion block. At this time, because a T-shaped second push rod is provided in the first push rod and the second push rod is connected to the first push rod by an elastic spring, the second push rod will squeeze the expansion block so that the two ends of the expansion block are respectively in conflict with the heat conducting plate and the second push rod. When the expansion block absorbs the heat transferred from the heat conducting plate, the volume of the expansion block will increase. The second push rod will move downward under the action of pressure, thereby squeezing the elastic spring. When the water gradually increases, due to the gravity of the hot water, the second push rod can squeeze the alarm button faster than relying entirely on the gravity and pressure of the hot water, thereby enabling faster alarming. The leak is blocked by the blocking component, avoiding excessive waste of resources while also alerting the surrounding personnel earlier, thereby protecting the safety of personnel.

[0017] A further improvement of the technical solution of the present utility model is that: the pop-up component includes a top block, a card slot is provided on the top block, the top block is slidably connected to the second shell, a reset spring is fixedly connected to one side of the top block, the other end of the reset spring is fixedly connected to the second shell, the other end of the top block is fixedly connected to the buzzer, an L-shaped baffle is fixedly connected to the bottom of the bottom plate, the baffle is slidably connected to the first shell, the other end of the baffle is fixedly connected to a card block, and the card block is slidably connected to the second shell.

[0018] The above-mentioned technical solution is adopted. In this solution, when the base plate is in a normal state, the return spring is in a compressed state. When the base plate moves downward under pressure, the base plate will drive the L-shaped baffle to move downward, and the L-shaped baffle will drive the card block fixedly connected to it to move downward and disengage from the card slot. At this time, because the card block moves downward, the baffle in the second shell pushes the buzzer fixedly connected to it to move outward under the action of the return spring, and the buzzer will push the rotating plate rotatably connected to the second shell to be exposed. Then, the buzzer can emit an alarm sound under the action of the external control device. By placing the buzzer in the second shell, it can avoid the influence of external environmental factors on the buzzer, thereby causing damage to the buzzer.

[0019] A further improvement of the technical solution of the present utility model is that the blocking component includes a baffle, a partial cross-section of the baffle is L-shaped, the baffle is slidingly connected to the compensator body, a connecting rod is fixedly connected to the baffle, the connecting rod is slidingly connected to the protective shell, an electric push rod is fixedly connected to the platform, the output end of the electric push rod is fixedly connected to the connecting rod, and a rubber sealing layer is provided on the surface of the baffle away from the connecting rod.

[0020] The above-mentioned technical solution is adopted. In this solution, when the alarm button is squeezed, the output end of the electric push rod begins to recover under the control of the external controller. At this time, the connecting rod fixedly connected to its output end will drive the baffle to move. Because a rubber sealing gasket is provided on one side of the baffle and the baffle part is L-shaped, when the output end of the electric push rod is completely recovered, the baffle will move to the gap and block the gap completely. There are also circulation holes on the baffle to facilitate the circulation of hot water, thereby preventing hot water from continuing to leak, avoiding more waste of resources while protecting the safety of surrounding people.

[0021] A further improvement of the technical solution of the utility model is that a scraper is fixedly connected to one side of the protective shell.

[0022] The above technical solution is adopted. In this solution, because the sleeve and the outer sleeve of the sleeve compensator are slidingly connected, during daily work, the sliding of the sleeve may bring water droplets or dirt adhered to the outer surface into the protective shell. By providing a scraper, the water droplets and dirt on the surface can be cleaned, thereby preventing interference from external factors and making the detection results more accurate.

[0023] A further improvement of the technical solution of the utility model is that a sponge is provided inside the scraper.

[0024] The above technical solution is adopted, in which a sponge is provided to absorb water droplets or water stains on the outer surface of the sleeve, thereby preventing the sleeve from sliding and bringing external water into the protective shell, thereby ensuring more accurate detection results.

[0025] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0026] 1. The utility model provides a thermal compensator suitable for pipelines. When a gap (such as point A in the attached figure) between the sleeve and the outer sleeve of the compensator body (the compensator body refers to the sleeve compensator, which is a mature technology in the existing technology and will not be described in detail) leaks, the leaked hot water will leak into the protective shell through the gap. A rubber ring is provided in the protective shell to ensure the sealing inside the protective shell. At this time, the hot water will quickly fill the protective shell and squeeze the detection component. After detecting the pressure, the detection component will press the alarm button. At this time, the alarm button will transmit a signal to the external controller. At the same time, the detection component also controls the pop-up component to make the buzzer pop out. The external controller controls the blocking component and the buzzer to work, and at the same time transmits the alarm signal to notify the staff to carry out maintenance. The external controller controls the buzzer to warn and drive away the surrounding personnel, thereby protecting the safety of the personnel. The controller controls the blocking component to block the leaking gap to prevent continuous leakage, thereby reducing the waste of resources. By providing a blocking component, a detection component and a pop-up component for use in conjunction with each other, leakage can be detected and stopped as soon as it occurs, thereby avoiding waste of resources and protecting the safety of personnel.

[0027] 2. The utility model provides a thermal compensator suitable for pipelines. When hot water in the pipeline leaks, the hot water will fill the protective shell and squeeze the bottom plate due to its own gravity and the pressure in the pipeline. At this time, the bottom plate moves downward and squeezes the pressure spring. At this time, the pressure spring is in a compressed state. The bottom plate will continue to move downward and squeeze the alarm button through the first push rod fixedly connected below it, thereby controlling the blocking component and the buzzer to work through the external controller, thereby achieving the purpose of detection.

[0028] 3. The utility model provides a thermal compensator suitable for pipelines. When the speed of the leaking hot water is not very fast, it takes a certain amount of time to press the alarm button. At this time, the hot water will flow through the protective shell into the first shell at the bottom thereof. At this time, the bottom plate will move downward but will not touch the alarm button. By arranging a heat conducting plate at the end of the bottom plate away from the pressure spring, the heat of the hot water will be transferred to the expansion block. At this time, because a T-shaped second push rod is arranged in the first push rod and the second push rod is connected to the first push rod by an elastic spring, the second push rod will squeeze the expansion block so that the two ends of the expansion block respectively collide with the heat conducting plate and the second push rod. When the expansion block absorbs the heat transferred from the heat conducting plate, the volume of the expansion block will increase. The second push rod will move downward under the action of pressure, thereby squeezing the elastic spring. When the water gradually increases, due to the gravity of the hot water, the second push rod can squeeze the alarm button faster than relying entirely on the gravity and pressure of the hot water, thereby enabling faster alarming. The leak is blocked by the blocking component, avoiding excessive waste of resources while also alerting the surrounding personnel earlier, thereby protecting the safety of the personnel.

[0038] The present invention is further described in detail below with reference to the embodiments:

[0039] Example

[0040] like Figure 1 and Figure 2 As shown, the utility model provides a thermal compensator suitable for a pipeline, comprising:

[0041] Compensator body 1, an annular protective shell 2 is fixedly connected to the outside of the compensator body 1, a platform 3 is fixedly connected to the protective shell 2, a through groove is provided on the outside of the protective shell 2, a first shell 4 is provided on the side of the protective shell 2 close to the through groove, the first shell 4 is threadedly connected to the protective shell 2, a second shell 5 is fixedly connected to one side of the first shell 4, an alarm button 6 is provided in the first shell 4, a buzzer 7 is provided in the second shell 5, and a rubber ring 8 is fixedly connected to the protective shell 2;

[0042] A detection component is located in the first housing 4 and is used to detect whether the compensator body 1 is leaking;

[0043] A pop-up component is located in the second housing 5 and is used to control the position of the buzzer 7;

[0044] The blocking component is located inside the protective shell 2 and is used to block the place where the compensator body 1 leaks.

[0045] In this embodiment, when the gap between the sleeve and the outer sleeve of the compensator body 1 (the compensator body 1 refers to the sleeve compensator, and because the sleeve compensator is a mature technology in the prior art, it will not be described in detail) leaks (such as point A in the accompanying drawings), the leaked hot water will leak into the protective shell 2 through the gap (and because the sleeve and the outer sleeve of the sleeve compensator are slidingly connected, the protective shell is slidingly connected to the sleeve through a rubber ring). By arranging a rubber ring 8 in the protective shell 2, the sealing inside the protective shell 2 can be ensured. At this time, the hot water will quickly fill the protective shell 2 and squeeze it. The detection component will press the alarm button 6 after detecting the pressure. At this time, the alarm button 6 will transmit the signal to the external controller. At the same time, the detection component also controls the pop-up component to make the buzzer 7 pop out. The blocking component and the buzzer 7 are controlled by the external controller to work, and the alarm signal is transmitted at the same time to notify the staff to carry out maintenance. The external controller controls the buzzer 7 to warn and drive away the surrounding personnel, thereby protecting the safety of the personnel. The controller controls the blocking component to block the leaking gap to prevent continuous leakage, thereby reducing the waste of resources. By setting up the blocking component, the detection component and the pop-up component for use together, the leak can be detected and stopped at the first time it occurs, thereby avoiding the waste of resources while also protecting the safety of the personnel.

[0046] like Figure 4 As shown, in this embodiment, preferably, the detection component includes a base plate 9, which is slidingly connected to the first shell 4, a pressure spring 10 is fixedly connected to one side of the base plate 9, the other end of the pressure spring 10 is fixedly connected to the first shell 4, and the end of the base plate 9 close to the pressure spring 10 is fixedly connected to the first push rod 11.

[0047] When the hot water in the pipeline leaks, the hot water fills the protective shell 2 and squeezes the bottom plate 9 due to its own gravity and the pressure in the pipeline. At this time, the bottom plate 9 moves downward and squeezes the pressure spring 10. At this time, the pressure spring 10 is in a compressed state. The bottom plate 9 will continue to move downward and squeeze the alarm button 6 through the first push rod 11 fixedly connected below it, thereby controlling the blocking component and the buzzer 7 to work through the external controller, thereby achieving the purpose of detection.

[0048] like Figure 5 As shown, preferably, the detection component also includes a heat conducting plate 12, which is fixedly connected to the side of the base plate 9 away from the pressure spring 10, and a second push rod 13 with a T-shaped arrangement is slidably connected in the first push rod 11, and an elastic spring 14 is fixedly connected to one side of the second push rod 13, and the other end of the elastic spring 14 is fixedly connected to the first push rod 11, and an expansion block 15 is provided between the second push rod 13 and the heat conducting plate 12, and the two ends of the expansion block 15 respectively conflict with the heat conducting plate 12 and the second push rod 13.

[0049] When the speed of the leaking hot water is not very fast, it takes a certain amount of time to press the alarm button 6. At this time, the hot water will flow through the protective shell 2 to the first shell 4 at the bottom thereof. At this time, the bottom plate 9 will move downward but will not touch the alarm button 6. By providing a heat conducting plate at the end of the bottom plate 9 away from the pressure spring 10, the heat of the hot water will be transferred to the expansion block 15. At this time, because a T-shaped second push rod 13 is provided in the first push rod 11 and the second push rod 13 is connected to the first push rod 11 by an elastic spring 14, the second push rod 13 will squeeze the expansion block 15, so that the two ends of the expansion block 15 are respectively connected to the conductive plate. The heat plate 12 and the second push rod 13 conflict with each other. When the expansion block 15 absorbs the heat transferred from the heat conducting plate 12, the volume of the expansion block 15 will increase, and the second push rod 13 will move downward under the action of pressure to squeeze the elastic spring 14. When the water gradually increases, due to the gravity of the hot water, the second push rod 13 can squeeze the alarm button 6 faster than relying entirely on the gravity and pressure of the hot water, so that the alarm can be issued faster, and the leakage can be blocked by the blocking component. While avoiding excessive waste of resources, it can also remind the surrounding people earlier, thereby protecting the safety of the people.

[0050] like Figure 6 As shown, preferably, the pop-up component includes a top block 16, a card slot 20 is opened on the top block 16, the top block 16 is slidably connected to the second shell 5, a return spring 17 is fixedly connected to one side of the top block 16, the other end of the return spring 17 is fixedly connected to the second shell 5, the other end of the top block 16 is fixedly connected to the buzzer 7, an L-shaped baffle 18 is fixedly connected to the bottom of the bottom plate 9, the baffle 18 is slidably connected to the first shell 4, the other end of the baffle 18 is fixedly connected to a card block 19, and the card block 19 is slidably connected to the second shell 5.

[0051] When the base plate 9 is in a normal state, the return spring 17 is in a compressed state. When the base plate 9 moves downward under pressure, the base plate 9 will drive the L-shaped baffle 18 to move downward, and the L-shaped baffle 18 will drive the block 19 fixedly connected thereto to move downward and disengage from the slot 20. At this time, because the block 19 moves downward, the baffle 21 in the second shell 5 pushes the buzzer 7 fixedly connected thereto to move outward under the action of the return spring 17. The buzzer 7 will push the rotating plate rotatably connected to the second shell 5 to be exposed, and then the buzzer 7 can emit an alarm sound under the action of the external control device. By placing the buzzer 7 in the second shell 5, the external environmental factors can be prevented from affecting the buzzer 7 and causing damage to the buzzer 7.

[0052] like Figure 7As shown, preferably, the blocking component includes a baffle 21, a partial cross-section of the baffle 21 is L-shaped, the baffle 21 is slidingly connected to the compensator body 1, a connecting rod 22 is fixedly connected to the baffle 21, the connecting rod 22 is slidingly connected to the protective shell 2, an electric push rod 23 is fixedly connected to the platform 3, the output end of the electric push rod 23 is fixedly connected to the connecting rod 22, and a rubber sealing layer 24 is provided on the surface of the baffle 21 away from the connecting rod 22.

[0053] When the alarm button 6 is squeezed, the output end of the electric push rod 23 begins to recover under the control of the external controller. At this time, the connecting rod 22 fixedly connected to its output end will drive the baffle 21 to move. Because a rubber sealing gasket is provided on one side of the baffle 21 and the baffle 21 is partially L-shaped, when the output end of the electric push rod 23 is completely recovered, the baffle 21 will move to the gap and block the gap completely. The baffle 21 is also provided with a circulation hole to facilitate the circulation of hot water, thereby preventing the hot water from continuing to leak, avoiding more waste of resources while also protecting the safety of people around.

[0054] like Figure 3 As shown, preferably, a scraper 25 is fixedly connected to one side of the protective shell 2 .

[0055] Because the sleeve and outer sleeve of the sleeve compensator are connected in a sliding manner, during daily operation, the sliding of the sleeve may bring water droplets or dirt adhered to the outer surface into the protective shell 2. By providing a scraper 25, the water droplets and dirt on the surface can be cleaned, thereby preventing interference from external factors and making the detection results more accurate.

[0056] like Figure 3 As shown, preferably, a sponge 26 is provided inside the scraper 25 .

[0057] The sponge 26 can absorb water droplets or water stains on the outer surface of the sleeve, thereby preventing the sleeve from sliding and bringing external water into the protective shell 2, thereby ensuring a more accurate detection result.

[0058] The working principle of this thermal compensator suitable for pipelines is explained in detail below.

[0059] like Figure 1 - Figure 7As shown, when the gap between the sleeve and the outer sleeve of the compensator body 1 (the compensator body 1 refers to the sleeve compensator, because the sleeve compensator is a mature technology in the prior art, it will not be described in detail) leaks (such as point A in the accompanying figure), the leaked hot water will leak into the protective shell 2 through the gap. The rubber ring 8 is provided in the protective shell 2 to ensure the sealing inside the protective shell 2. At this time, the hot water will quickly fill the protective shell 2 and squeeze the detection component. After the detection component detects the pressure, it will press the alarm button 6. At this time, the alarm button 6 will transmit the signal to the external controller. At the same time, the detection component also controls the pop-up component to work, so that the buzzer 7 pops out. The external controller controls the blocking component and the buzzer 7 to work, and at the same time transmits the alarm signal to notify the staff to carry out maintenance. The external controller controls the buzzer 7 to work in order to warn and drive away the surrounding personnel, thereby protecting the safety of the personnel. The controller controls the blocking component to work in order to block the leaking gap to prevent continuous leakage, thereby reducing the waste of resources. By providing a blocking component, a detection component and a pop-up component for use in conjunction, the leak can be detected and stopped at the first moment it occurs, thereby avoiding waste of resources while protecting personnel safety. When the hot water in the pipeline leaks, the hot water will squeeze the bottom plate 9 due to its own gravity and the pressure in the pipeline while filling the protective shell 2. At this time, the bottom plate 9 moves downward and squeezes the pressure spring 10. At this time, the pressure spring 10 is in a compressed state. The bottom plate 9 will continue to move downward and squeeze the alarm button 6 through the first push rod 11 fixedly connected thereto, thereby controlling the blocking component and the buzzer 7 to work through the external controller, thereby achieving the purpose of detection. When the speed of the leaking hot water is not very fast, it takes a certain amount of time to press the alarm button 6. At this time, the hot water will flow through the protective shell 2 to the first shell 4 at the bottom thereof. At this time, the bottom plate 9 will move downward but will not touch the alarm button 6. By providing a heat conducting plate at the end of the bottom plate 9 away from the pressure spring 10, the heat of the hot water will be transferred to the expansion block 15. At this time, because a T-shaped second push rod 13 is provided in the first push rod 11 and the second push rod 13 is connected to the first push rod 11 by an elastic spring 14, the second push rod 13 will squeeze the expansion block 15, so that the two ends of the expansion block 15 are respectively connected to the conductive plate. The heat plate 12 and the second push rod 13 conflict with each other. When the expansion block 15 absorbs the heat transferred from the heat conducting plate 12, the volume of the expansion block 15 will increase, and the second push rod 13 will move downward under the action of pressure to squeeze the elastic spring 14. When the water gradually increases, due to the gravity of the hot water, the second push rod 13 can squeeze the alarm button 6 faster than relying entirely on the gravity and pressure of the hot water, thereby enabling faster alarming. The leak can be blocked by the blocking component, which can avoid excessive waste of resources while also reminding the surrounding personnel earlier, thereby protecting the safety of the personnel.When the base plate 9 is in a normal state, the return spring 17 is in a compressed state. When the base plate 9 moves downward under pressure, the base plate 9 will drive the L-shaped baffle 18 to move downward, and the L-shaped baffle 18 will drive the block 19 fixedly connected thereto to move downward and disengage from the slot 20. At this time, because the block 19 moves downward, the baffle 21 in the second shell 5 pushes the buzzer 7 fixedly connected thereto to move outward under the action of the return spring 17. The buzzer 7 will push the rotating plate rotatably connected to the second shell 5 to be exposed, and then the buzzer 7 can emit an alarm sound under the action of the external control device. By placing the buzzer 7 in the second shell 5, the external environmental factors can be prevented from affecting the buzzer 7 and causing damage to the buzzer 7. When the alarm button 6 is squeezed, the output end of the electric push rod 23 begins to retract under the control of the external controller. At this time, the connecting rod 22 fixedly connected to its output end drives the baffle 21 to move. Because the baffle 21 is provided with a rubber sealing gasket on one side and the baffle 21 is partially L-shaped, when the output end of the electric push rod 23 is fully retracted, the baffle 21 moves to the gap and completely blocks the gap. The baffle 21 also has a circulation hole to facilitate the circulation of hot water, thereby preventing the hot water from continuing to leak, avoiding further waste of resources and protecting the safety of surrounding personnel. Because the sleeve and outer sleeve of the sleeve compensator are connected in a sliding manner, during daily operation, the sliding of the sleeve may bring water droplets or dirt adhered to the outer surface into the protective shell 2. The scraper 25 can clean the water droplets and dirt on the surface, thereby preventing interference from external factors and ensuring more accurate detection results. The sponge 26 can absorb water droplets or water stains on the outer surface of the sleeve, thereby preventing the sleeve from sliding and bringing external water into the protective shell 2, thereby ensuring more accurate detection results.

[0060] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
