Description
Technical Field
[0001] This invention relates to the field of temperature and pressure transmitter technology, and more particularly to an underwater pressure and temperature integrated transmitter. Background Technology
[0002] Currently, transmitters are widely used in chemical, metallurgical, machinery, clean energy, and water treatment fields, such as pressure transmitters, temperature transmitters, and flow transmitters. In practical applications, it is often necessary to simultaneously measure the temperature and pressure of various media in the production process. In related technologies, multiple sets of cables and multiple DCS communication modules are mainly used to establish separate communication connections between the DCS and the pressure transmitter and the temperature gauge, respectively. The temperature signal collected by the temperature gauge and the pressure signal collected by the pressure transmitter are converted into a two-wire 4-20mA current signal, and then these two current signals are transmitted to the external device to achieve accurate measurement of temperature and pressure simultaneously.
[0003] In existing technologies, when measuring the temperature and pressure of water in deep water wells or chemical wells, the temperature and pressure transmitter needs to be lowered into the bottom wall of the well for measurement. If there are impurities or silt at the bottom of the well, the measuring end of the temperature and pressure transmitter will be inserted into the impurities or silt after being lowered to the bottom of the well, thus affecting the accuracy of the transmitter's measurement of the pressure and temperature of the water at the bottom of the well. Summary of the Invention
[0004] The purpose of this invention is to address the following shortcomings in the prior art: In the prior art, when measuring the temperature and pressure of water in deep water wells or chemical wells, it is necessary to insert the temperature and pressure transmitter into the bottom wall of the well for measurement. If there are impurities or silt at the bottom of the well, the measuring end of the temperature and pressure transmitter will be inserted into the impurities or silt after being lowered to the bottom of the well, thereby affecting the accuracy of the transmitter's measurement of the pressure and temperature of the water at the bottom of the well. Therefore, this invention proposes an integrated underwater pressure and temperature transmitter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An integrated underwater pressure and temperature transmitter includes a transmitter body, a fixed ring, and a base plate. The fixed ring is sleeved on the lower outer surface of the transmitter body. A sensor is installed on the transmitter body. A sliding groove is formed on the fixed ring, and a connecting block is fixedly connected in the sliding groove. The base plate is slidably connected to the bottom of the transmitter body.
[0007] A filter cylinder is fixedly connected to the base plate. Sliding grooves are respectively opened on both sides of the filter cylinder. The upper end of the filter cylinder is slidably connected in the sliding groove, and the vertical groove is slidably connected to the connecting block. Multiple support components are installed in a ring array on the outer surface of the base plate. The support components include a hinge plate, a flip plate, and a rotating rod. The rotating rod is fixedly connected to the base plate. One end of the hinge plate is rotatably connected to the rotating rod through the flip plate. A torsion spring is provided between the hinge plate and the rotating rod. A second magnetic block is fixedly connected to the end of the flip plate away from the hinge plate.
[0008] Two support rods are slidably connected to the fixed ring. A limiting plate is fixedly connected between the ends of the two support rods away from the base plate. A sealing rod is fixedly connected to the upper surface of the limiting plate. The limiting plate is shaped like a frustum.
[0009] Preferably, the support component further includes a pressing rod, one end of which is slidably connected to the base plate, and a tension spring is provided between the end of the pressing rod and the inner wall of the base plate. The base plate is provided with a placement groove for the sliding of the limiting plate.
[0010] Preferably, protrusions are fixedly connected to the two support rods respectively, and horizontal plates are fixedly connected to both sides of the lower end of the limiting plate respectively. The limiting plate is located directly below the transmitter body.
[0011] Preferably, the fixing ring has two through slots, and a sliding rod is slidably connected in each of the two through slots. Arc-shaped plates are installed on the two sliding rods in an equidistant array.
[0012] Preferably, a circular ring is slidably connected inside the fixed ring, a sponge ring is fixedly connected to the lower end of the circular ring, the inner wall of the sponge ring is slidably connected to the outer surface of the filter cartridge, and a plurality of push rods are fixedly connected to the upper end of the circular ring, all of which are slidably connected to the upper wall of the fixed ring.
[0013] Preferably, two clamping plates are slidably connected inside the fixing ring. Both clamping plates are arc-shaped and located on both sides of the sponge ring. Protrusions are fixedly connected to each of the two clamping plates.
[0014] Preferably, baffles are fixedly connected to the two clamps respectively, the upper end of the baffles is slidably connected to the through groove, a semi-circular block is fixedly connected to the side wall of the baffle near the slide rod, the arc plate is slidably connected to the semi-circular block, and a second spring is fixedly connected between the baffle and the inner wall of the through groove.
[0015] Preferably, the transmitter body has a mounting cavity slidably connected to the outer surface of the upper end, a plurality of first magnetic blocks are fixedly connected to the outer surface of the mounting cavity, the mounting cavity is fixedly connected between the upper ends of the two slide rods, and a water inlet is provided on the bottom wall of the mounting cavity.
[0016] Preferably, a first spring is fixedly connected to each side of the mounting cavity, and the end of the first spring away from the mounting cavity is fixedly connected to the outer wall of the fixing ring. The mounting cavity is fixedly connected to the upper end of the filter cartridge.
[0017] Preferably, a first spring is fixedly connected to each side of the mounting cavity, and the end of the first spring away from the mounting cavity is fixedly connected to the outer wall of the fixing ring. The mounting cavity is fixedly connected to the upper end of the filter cartridge.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. During the downward movement of the base plate, the limit plate can be pushed down by the horizontal plate. At this time, the limit plate is in the mounting groove on the base plate. At this time, the sealing rod on the limit plate is disengaged from the measuring hole on the transmitter body, so that water in the well can enter the measuring hole to measure the water pressure.
[0020] 2. The movement of the squeezing rod can push the flip plate on one side from a vertical state to a horizontal state. After the flip plate is unfolded, it is at the bottom of the well, which can increase the contact area between the bottom of the transmitter body and the ground, and prevent the sensor at the bottom of the transmitter body from contacting the silt or impurities at the bottom of the well. This allows the transmitter body to be submerged in water, which facilitates better measurement of water temperature and pressure. At the same time, the sensor is covered by a filter cartridge, which can prevent impurities in the water from approaching and adhering to the sensor during measurement, thus avoiding affecting the accuracy of the measurement.
[0021] 3. After the measurement is completed, use the external wiring to pull the transmitter body upward. When the transmitter body is removed from the water in the well, it is restricted by the protrusion during the upward movement of the base plate, which can push the support rod to move upward. During the upward movement of the support rod, the limit plate pushes the upper end of the sealing rod to insert into the measuring hole at the lower end of the transmitter body, which has a sealing effect on the measuring hole at the lower end of the transmitter body, so as to avoid dust accumulation in the measuring hole when it is not used for a long time, which would affect the measuring element.
[0022] 4. The squeezing rod no longer squeezes the flip plate, and the flip plate is reset under the pull of the torsion spring. After the flip plate is reset from the horizontal state to the vertical state, the first magnetic block and the second magnetic block have a mutual attraction effect, which ensures that the flip plate has a certain stability. Thus, after the transmitter body discharges water, it has an automatic closing effect on each component.
[0023] 5. As the slide bar moves upward, it continuously squeezes the baffle and clamp, causing them to move horizontally back and forth. This causes the clamp to intermittently squeeze the sponge ring, resulting in the water in the sponge ring being discharged. This achieves the effect of cleaning water and impurities from the surface during the upward repositioning of the filter cartridge. Attached Figure Description

Detailed Implementation
[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0036] Reference Figures 1-10 An integrated underwater pressure and temperature transmitter includes a transmitter body 1, a fixing ring 10, and a base plate 6. The fixing ring 10 is sleeved on the lower outer surface of the transmitter body 1. The surface of the fixing ring 10 is coated with a magnetic shielding material to prevent the first magnetic block 11 from affecting the internal components of the transmitter body 1. An external wiring 32 is electrically connected to the upper end of the transmitter body 1. A sealing sleeve 2 is sleeved between the outer surface of the transmitter body 1 and the external wiring 32. The transmitter body 1 is a device that converts water pressure into a pneumatic or electric signal for control and remote transmission. The transmitter body 1 can convert the physical pressure parameters of liquid, etc., sensed by the pressure sensing element sensor into a standard electrical signal. Therefore, a measuring hole is opened at the lower end of the transmitter body 1, and the pressure sensing element sensor is located in the measuring hole. Water in the measuring hole will be sensed by the pressure sensing element sensor. A mounting cavity 3 is slidably connected to the upper outer surface of the transmitter body 1. First springs 29 are fixedly connected to both sides of the mounting cavity 3. 29 The end away from the mounting cavity 3 is fixedly connected to the outer wall of the fixing ring 10. The mounting cavity 3 is fixedly connected to the upper end of the filter cartridge 5. Multiple first magnetic blocks 11 are fixedly connected to the outer surface of the mounting cavity 3. The mounting cavity 3 is fixedly connected between the upper ends of two sliding rods 12. A water inlet is opened on the bottom wall of the mounting cavity 3. Two through grooves are opened on the fixing ring 10. Sliding rods 12 are slidably connected in the two through grooves respectively. Arc-shaped plates 17 are installed on the two sliding rods 12 in an equidistant array. A circular ring 1 is slidably connected in the fixing ring 10. 9. A sponge ring 18 is fixedly connected to the lower end of the circular ring 19. The inner wall of the sponge ring 18 is slidably connected to the outer surface of the filter cartridge 5. Multiple push rods 20 are fixedly connected to the upper end of the circular ring 19. All push rods 20 are slidably connected to the upper wall of the fixed ring 10. When the sponge ring 18 absorbs water and impurities from the outer surface of the filter cartridge 5, it pushes the push rods 20 downward. The push rods 20 can push the circular ring 19 and the sponge ring 18 downward. At this time, the sponge ring 18 moves to the outside of the fixed ring 10, which is convenient for the staff to clean the sponge ring 18.
[0037] Two clamping plates 21 are slidably connected inside the fixed ring 10. Both clamping plates 21 are arc-shaped and located on both sides of the sponge ring 18. Protrusions 15 are fixedly connected to the two clamping plates 21 respectively. The clamping plates 21 are made of hard plastic and have a certain degree of toughness, so that the clamping plates 21 can squeeze the sponge ring 18 when moving in the center. A sensor 7 is installed on the transmitter body 1. The sensor 7 and the transmitter body 1 are an integral structure, forming a temperature and pressure transmitter. A sliding groove 26 is opened on the fixed ring 10 for the sliding of the filter cartridge 5. A connecting block 24 is fixedly connected inside the vertical groove 27. The bottom plate 6 is slidably connected to the bottom of the transmitter body 1. Baffles 30 are fixedly connected to the two clamping plates 21 respectively. The upper end of the baffle 30 is slidably connected inside the through groove. A semi-circular block 16 is fixedly connected to the side wall of the baffle 30 near the slide rod 12. The arc plate 17 is slidably connected to the semi-circular block 16. A second spring 31 is fixedly connected between the baffle 30 and the inner wall of the through groove.
[0038] A filter cylinder 5 is fixedly connected to the base plate 6. Vertical grooves 27 are respectively opened on both sides of the filter cylinder 5. The upper end of the filter cylinder 5 is slidably connected in the groove 26, and the vertical groove 27 is slidably connected to the connecting block 24. Multiple support components are installed in a ring array on the outer surface of the base plate 6. The support components include a hinge plate 9, a flip plate 4, and a rotating rod 25. The rotating rod 25 is fixedly connected to the base plate 6. One end of the hinge plate 9 is rotatably connected to the rotating rod 25 through the flip plate 4. A torsion spring is provided between the hinge plate 9 and the rotating rod 25. A second magnetic block 28 is fixedly connected to the end of the flip plate 4 away from the hinge plate 9. The support components also include a pressing rod 13. One end of the pressing rod 13 is slidably connected in the base plate 6. A tension spring is provided between the end of the pressing rod 13 and the inner wall of the base plate 6. The tension spring is used to pull the pressing rod 13 to move back. A placement groove for the sliding of the limiting plate 8 is opened on the base plate 6. When the base plate 6 moves, the limiting plate 8 can slide into the placement groove.
[0039] Two support rods 14 are slidably connected to the fixed ring 10. A limiting disk 8 is fixedly connected between the ends of the two support rods 14 away from the base plate 6. A sealing rod 22 is fixedly connected to the upper surface of the limiting disk 8. After the upper end of the sealing rod 22 enters the measuring hole, it can seal the measuring hole. The limiting disk 8 is set in the shape of a frustum. A protrusion 15 is fixedly connected to the two support rods 14 respectively. A horizontal plate 23 is fixedly connected to both sides of the lower end of the limiting disk 8 respectively. The limiting disk 8 is located directly below the transmitter body 1.
[0040] In this invention, when in use, as shown in the appendix Figure 1 As shown, after the transmitter body 1 is immersed in water, the water will enter the mounting cavity 3 through the inlet. After the water enters the mounting cavity 3, it will increase the gravity of the mounting cavity 3 itself. The mounting cavity 3 slides downward on the transmitter body 1 and pushes the filter cartridge 5 to slide downward in the sliding groove 26 on the fixing ring 10. The filter cartridge 5 pushes the base plate 6 to move downward away from the transmitter body 1. During the downward movement of the base plate 6, it can push the limiting plate 8 downward through the horizontal plate 23. At this time, the limiting plate 8 is in the mounting groove on the base plate 6. At this time, the sealing rod 22 on the limiting plate 8 is disengaged from the measuring hole on the transmitter body 1, so that the water in the well can enter the measuring hole for water pressure measurement.
[0041] As the base plate 6 moves downward and the limiting plate 8 enters the placement slot on the base plate 6, because the limiting plate 8 is frustum-shaped, its inclined sidewall can push the pressing rod 13 to slide on the base plate 6. The movement of the pressing rod 13 can push the flipping plate 4 on one side to flip from a vertical state to a horizontal state, as shown in the attached figure. Figure 2The diagram shows the transmitter body 1 in the water. After the flip plate 4 is unfolded, it is at the bottom of the well, which increases the contact area between the bottom of the transmitter body 1 and the ground. At the same time, the upper end of the transmitter body 1 is pulled by the external wiring 32. When the base plate 6 contacts the bottom of the well, the external wiring 32 is tightened, and the transmitter body 1 no longer moves down. The sensor 7 at the lower end of the transmitter body 1 comes into contact with the silt or impurities at the bottom of the well, so that the transmitter body 1 is in the water, which facilitates better measurement of water temperature and pressure. At the same time, the sensor 7 is covered by the filter cartridge 5, which can prevent impurities in the water from approaching and adhering to the sensor 7 during measurement, thus avoiding affecting the accuracy of the measurement.
[0042] After the measurement is completed, the transmitter body 1 is pulled upward using the external wiring 32. When the transmitter body 1 is removed from the water in the well, the water in the mounting cavity 3 will automatically flow out through the inlet, reducing the weight of the mounting cavity 3. The mounting cavity 3 moves upward under the elastic force of the first spring 29, and drives the filter cartridge 5 to move upward and reset. When the mounting cavity 3 pulls the base plate 6 upward via the slide rod 12, the base plate 6 is separated from the limiting plate 8. During the upward movement of the base plate 6, it is restricted by the protrusion 15, which can push the support rod 14 upward. As the support rod 14 moves upward, the limiting plate 8 pushes the upper end of the sealing rod 22 into the measuring hole at the lower end of the transmitter body 1, thereby sealing the measuring hole at the lower end of the transmitter body 1 and preventing dust from accumulating in the measuring hole when not in use for a long time, which could affect the measuring element.
[0043] After the upper end of the sealing rod 22 is inserted into the measuring hole at the lower end of the transmitter body 1, the base plate 6 is then in contact with the bottom wall of the fixing ring 10. As the limiting plate 8 separates from the base plate 6, the limiting plate 8 no longer limits the squeezing rod 13. The multiple squeezing rods 13 are reset and moved under the pull of the tension spring, so that the squeezing rods 13 no longer squeeze the flip plate 4. The flip plate 4 is reset under the pull of the torsion spring. After being reset and flipped from the horizontal state to the vertical state, the first magnetic block 11 and the second magnetic block 28 have a mutual attraction effect, ensuring that the flip plate 4 has a certain stability. Thus, after the transmitter body 1 discharges water, it has an automatic closing effect on each component.
[0044] Simultaneously, as the filter cartridge 5 moves upward, the water and impurities adhering to its surface can be absorbed by the sponge ring 18 inside the fixing ring 10, and the impurities will be scraped off. At the same time, as the arc plate 17 moves upward with the slide rod 12, multiple arc plates 17 are successively limited by the semi-circular block 16, which can push the baffle 30 and the clamping plate 21 to move and compress the second spring 31. Since the clamping plate 21 is made of hard plastic and has a certain toughness, it can squeeze the sponge ring 18 during the movement of the two clamping plates 21 in the center. Since the water on the surface of the filter cartridge 5 is absorbed by the sponge ring 18, it can be discharged under the pressure of the clamping plate 21. Therefore, as the slide rod 12 moves upward continuously, it can continuously squeeze the baffle 30 and the clamping plate 21 to move horizontally back and forth, so that the clamping plate 21 intermittently squeezes the sponge ring 18, causing the water inside the sponge ring 18 to be discharged, thus achieving the effect of cleaning the water and impurities on the surface during the upward repositioning process of the filter cartridge 5.
[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
