Description

Technical Field

[0001] The invention relates to the technical field of cooling tower outlet water temperature measurement, in particular to an anti-loosening cooling tower outlet water temperature measurement device. Background Art

[0002] The cooling tower performance test requires the detection of the cooling tower outlet water temperature. The outlet water temperature is the most important parameter in the cooling tower prototype observation test. Generally, a temperature sensor that can wirelessly transmit monitoring data is installed at the end of the outlet pipe of the cooling tower to monitor the cooling tower outlet water temperature in real time.

[0003] When the existing cooling tower outlet water temperature measuring device is installed at the end of the outlet water pipe, its detection rod needs to be inserted into the pipe and in contact with the outlet water. When the outlet water flows inside the pipe, especially when it flows at high speed, it will cause continuous impact on the rod part, which can easily cause the rod part to shake and loosen, thereby affecting the service life of the cooling tower outlet water temperature measuring device.

[0007] Furthermore, the threaded tube is communicated with the interior of the water outlet pipe body, and the vertical center axis of the threaded tube coincides with the vertical center axis of the water outlet pipe body.

[0008] Furthermore, a communication pipe is provided inside the placement base, and the communication pipe is communicated with the oil pipe, and a piston rod is passed through the end of the communication pipe away from the oil pipe.

[0009] Furthermore, the outer diameter of the limiting joint is larger than the inner diameter of the top opening of the threaded tube, and the outer diameter of the limiting joint is smaller than the outer diameter of the threaded tube, and the threaded connection sleeve is located outside the limiting joint.

[0010] Furthermore, the inner port structure of the threaded connection sleeve is adapted to the outer port structure of the threaded pipe, and the temperature sensor is threadedly connected to the threaded pipe through the threaded connection sleeve.

[0011] Furthermore, the circular pressure plate is located directly above the piston rod, and the arc-shaped plate is transmission-connected to the piston rod via a telescopic rod and an oil pipe.

[0012] Furthermore, the reinforcement groove and the clamping piece are arranged one to one, and the inner opening size of the reinforcement groove is adapted to the thickness size of the arc plate.

[0013] Furthermore, the inner diameter of the top opening of the threaded tube is smaller than the diameter of its inner wall, and a sealing ring is provided at the top of the inner wall of the threaded tube.

[0014] Furthermore, a sealing plate is attached to the lower surface of the sealing ring, and the outer diameter of the sealing plate is larger than the inner diameter of the sealing ring and smaller than the inner diameter of the threaded tube. A torsion spring is provided on one side of the sealing plate, and the sealing plate is elastically connected to the threaded tube through the torsion spring.

[0015] Furthermore, a reinforcement component is fixed to the top of the inner wall of the water outlet pipe on one side of the oil pipe, and the reinforcement component includes an oil transmission box, an arc-shaped oil pressure plate and a reinforcement support plate.

[0016] The present invention provides a cooling tower outlet water temperature measuring device that is anti-loosening and has the following beneficial effects:

[0017] 1. The anti-loosening cooling tower outlet water temperature measuring device rotates the threaded connection sleeve to make it threadedly connected to the threaded pipe. During the threaded connection process, the threaded connection sleeve rotates and descends along the outer wall of the threaded pipe, so that the circular pressure plate presses down to press the piston rod into the connecting pipe inside the mounting base. At this time, the oil inside the connecting pipe pushes the oil inside the oil pipe to make the telescopic rod carrying the arc plate and the clamping piece extend, so that the clamping piece can be just stuck into the reinforcement groove, thereby reinforcing the rod body of the temperature sensor. While the rod body of the temperature sensor is being processed, the arc plate can guide the outlet water in the water outlet pipe body to reduce the impact force on the rod body, so as to further prevent the rod body from shaking due to the impact force of the water flow, thereby playing an effective anti-loosening role for the temperature sensor, so as to prevent the long-term shaking of the rod body from causing the installation of the temperature sensor to become loose, and also to prevent the long-term shaking of the rod body from affecting the service life of the temperature sensor.

[0018] 2. This anti-loosening cooling tower outlet water temperature measuring device has a structure that, when the temperature sensor is pulled out, the sealing plate loses its downward pressure and rotates upward and resets via the torsion spring until the sealing plate fits the sealing ring. At this time, even if the outlet water inside the outlet pipe body continues to flow, the upward force will only be provided from the bottom of the sealing plate, making the sealing plate and the sealing ring fit more tightly, thereby preventing the outlet water from leaking out of the top opening of the threaded pipe after the temperature sensor is pulled out.

[0019] 4. This anti-loosening cooling tower outlet water temperature measuring device, when the outlet water is transmitted along the inside of the outlet pipe, the thrust generated by the water flow pushes the arc-shaped oil pressure plate so that its rod body is pressed into the inside of the oil transmission box, so that the oil inside the oil transmission box moves to push the reinforcement support plate to extend, so that the reinforcement support plate is attached to the lower part of the rod body of the temperature sensor, thereby pushing the arc-shaped oil pressure plate through water flow transmission to transmit the reinforcement support plate to support the lower part of the rod body of the temperature sensor, thereby improving the stability of the lower part of the rod body of the temperature sensor.

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] Such as Figure 1-Figure 7As shown, the present invention provides a technical solution: a cooling tower outlet water temperature measuring device with anti-loosening, comprising an outlet pipe body 1 and an anti-loosening installation component 2, the surface of the outlet pipe body 1 is provided with an anti-loosening installation component 2, the anti-loosening installation component 2 includes a placement base 201, a threaded pipe 202, a piston rod 203, an oil pipe 204, a telescopic rod 205, an arc plate 206, a clamping piece 207, a temperature sensor 208, a limit bone 209, a threaded connection sleeve 210, a circular pressure plate 211 and a reinforcement groove 212, a threaded pipe 202 is provided in the middle of the top surface of the placement base 201, and the threaded pipe 202 is provided. 02 is provided with piston rods 203 on both sides of the top surface of the mounting base 201, and oil pipes 204 are provided on both sides of the top of the inner wall of the water outlet pipe body 1, and a telescopic rod 205 is provided at the end of the oil pipe 204, an arc plate 206 is fixed at the end of the telescopic rod 205, and clamping pieces 207 are evenly distributed on the side of the arc plate 206, a temperature sensor 208 is provided inside the threaded tube 202, and a limit bone node 209 is provided on the upper surface of the rod body of the temperature sensor 208, and the rod body of the temperature sensor 208 is rotatably connected to a threaded connection sleeve 210, and the outer surface of the threaded connection sleeve 210 is fixed to the outer surface of the threaded connection sleeve 210. A circular pressure plate 211 is rotatably connected to the bottom of the wall, and a reinforcement groove 212 is equidistantly provided on the lower surface of the rod body of the temperature sensor 208. The threaded tube 202 is connected to the inside of the water outlet pipe body 1, and the vertical center axis of the threaded tube 202 coincides with the vertical center axis of the water outlet pipe body 1. A connecting pipe is provided inside the mounting base 201, and the connecting pipe is connected to the oil pipe 204, and a piston rod 203 is provided inside the end of the connecting pipe away from the oil pipe 204. The outer diameter of the limiting bone node 209 is larger than the inner diameter of the top opening of the threaded tube 202, and the outer diameter of the limiting bone node 209 is larger than the inner diameter of the top opening of the threaded tube 202. The outer diameter of the threaded tube 202 is smaller than that of the threaded connection sleeve 210, and the threaded connection sleeve 210 is located outside the limiting joint 209. The inner opening structure of the threaded connection sleeve 210 is adapted to the outer opening structure of the threaded tube 202, and the temperature sensor 208 is threadedly connected to the threaded tube 202 through the threaded connection sleeve 210. The circular pressure plate 211 is located directly above the piston rod 203, and the arc plate 206 is transmission-connected to the piston rod 203 through the telescopic rod 205 and the oil pipe 204. The reinforcement groove 212 and the clamping piece 207 are arranged one-to-one, and the inner opening size of the reinforcement groove 212 is adapted to the thickness size of the arc plate 206.

[0030] The specific operation is as follows: the rod of the temperature sensor 208 is inserted through the threaded tube 202 into the interior of the water outlet pipe body 1. The limit joint 209, whose outer diameter is larger than the inner diameter of the top opening of the threaded tube 202, can limit the insertion depth of the rod of the temperature sensor 208, so that the reinforcement groove 212 of the rod is flush with the clamping piece 207.

[0031] Then, the threaded connection sleeve 210 is manually rotated to be threadedly connected to the threaded tube 202. During the threaded connection process, the threaded connection sleeve 210 rotates and descends along the outer wall of the threaded tube 202, so that the circular pressure plate 211 applies downward pressure on the top of the piston rod 203, causing the piston rod 203 to retract into the connecting pipe inside the mounting base 201. At this time, the oil inside the connecting pipe acts as a transmission medium to push the oil inside the oil pipe 204, causing the telescopic rod 205 to extend with the curved plate 206 and the clamping piece 207, so that the clamping piece 207 can be exactly stuck in the reinforcement groove 212, thereby reinforcing the rod part of the temperature sensor 208.

[0032] When the water out of the tower is transmitted along the inside of the water outlet pipe body 1, when the water flows through the rod part of the temperature sensor 208, the water flow is guided by the arc plate 206 to reduce the impact force on the rod part, and the arc plate 206 and the clamping piece 207 reinforce the rod part of the temperature sensor 208 to further prevent the rod part from shaking due to the impact force of the water flow, thereby playing an effective anti-loosening effect on the temperature sensor 208, preventing the long-term shaking of the rod part from causing the installation of the temperature sensor 208 to become loose, and also avoiding the long-term shaking of the rod part affecting the service life of the temperature sensor 208, and the clamping piece 207 is elastically connected to the arc plate 206 through a spring, which is not shown in the spring figure, thereby preventing the water flow impact force on the arc plate 206 from being transmitted to the rod part of the temperature sensor 208.

[0033] like Figure 1-Figure 7 As shown, the inner diameter of the top opening of the threaded tube 202 is smaller than the diameter of its inner wall, and a sealing ring 3 is provided on the top of the inner wall of the threaded tube 202. A sealing plate 4 is attached to the lower surface of the sealing ring 3, and the outer diameter of the sealing plate 4 is larger than the inner diameter of the sealing ring 3 but smaller than the inner diameter of the threaded tube 202. A torsion spring 5 is provided on one side of the sealing plate 4, and the sealing plate 4 is elastically connected to the threaded tube 202 through the torsion spring 5.

[0034] The specific operation is as follows: the threaded connection sleeve 210 is rotatably connected to the rod portion of the temperature sensor 208 and can slide up and down along the surface of the rod portion. The sliding area is restricted by the limit joint 209. When the rod portion of the temperature sensor 208 passes through the interior of the threaded tube 202, the bottom end of the rod portion contacts the sealing plate 4 and exerts downward pressure on it, causing the sealing plate 4 to rotate downward via the torsion spring 5, allowing the rod portion to be inserted into the interior of the water outlet pipe body 1;

[0035] When the temperature sensor 208 needs to be removed later, the threaded connection sleeve 210 is first rotated to slide upward along the rod body until the threaded connection sleeve 210 is separated from the threaded tube 202. As the threaded connection sleeve 210 rises, the circular pressure plate 211 rises accordingly. At the same time, the piston rod 203 loses the downward pressure and rises synchronously, causing the telescopic rod 205 to retract into the oil pipe 204. At this time, the arc plates 206 move away from each other and the clamping piece 207 leaves the reinforcement groove 212. At this time, the temperature sensor 208 can be pulled out.

[0036] When the temperature sensor 208 is pulled out, the sealing plate 4 loses the downward pressure and is reset by rotating upward through the torsion spring 5 until the sealing plate 4 is in contact with the sealing ring 3. At this time, even if the water out of the tower inside the outlet pipe body 1 continues to be transmitted, an upward force will only be provided from the bottom of the sealing plate 4, making the sealing plate 4 and the sealing ring 3 fit more tightly, thereby preventing the water out of the tower from leaking from the top opening of the threaded pipe 202 after the temperature sensor 208 is pulled out.

[0037] like Figure 1-Figure 7 As shown, a reinforcement component 6 is fixed to the top of the inner wall of the water outlet pipe body 1 on one side of the oil pipe 204. The reinforcement component 6 includes an oil transmission box 601, an arc-shaped oil pressure plate 602 and a reinforcement support plate 603. The rear end bottom of the oil transmission box 601 is penetrated by the arc-shaped oil pressure plate 602, and the middle bottom of the oil transmission box 601 is penetrated by the reinforcement support plate 603. The reinforcement support plate 603 is in contact with the lower part of the rod body of the temperature sensor 208.

[0038] The specific operation is as follows: after the temperature sensor 208 is installed, the arc plate 206 and the clamping piece 207 clamp the rod part of the temperature sensor 208. When the outflowing water is transmitted along the inside of the water outlet pipe body 1, the thrust generated by the water flow pushes the arc-shaped oil pressure plate 602 to press its rod part into the oil transmission box 601, so that the oil inside the oil transmission box 601 moves to push the reinforcement support plate 603 to extend, so that the reinforcement support plate 603 is attached to the lower part of the rod part of the temperature sensor 208. The water flow is transmitted to push the arc-shaped oil pressure plate 602 to transmit the reinforcement support plate 603 to support the lower part of the rod part of the temperature sensor 208, so as to improve the stability of the lower part of the rod part of the temperature sensor 208. The arc-shaped structure of the arc-shaped oil pressure plate 602 can guide the flow of water without clogging.

[0039] In summary, when using the anti-loosening cooling tower outlet water temperature measuring device, the rod portion of the temperature sensor 208 is first inserted through the threaded tube 202 into the interior of the outlet pipe body 1. The limiting bone 209, whose outer diameter is larger than the inner diameter of the top opening of the threaded tube 202, can limit the insertion depth of the rod portion of the temperature sensor 208, so that the reinforcement groove 212 of the rod portion is flush with the clamping piece 207.

[0040] When the rod portion of the temperature sensor 208 passes through the threaded tube 202, the bottom end of the rod portion contacts the sealing plate 4 and exerts downward pressure thereon, causing the sealing plate 4 to rotate downward via the torsion spring 5, allowing the rod portion to be inserted into the interior of the water outlet pipe body 1;

[0041] Then, the threaded connection sleeve 210 is manually rotated to be threadedly connected to the threaded tube 202. During the threaded connection process, the threaded connection sleeve 210 rotates and descends along the outer wall of the threaded tube 202, so that the circular pressure plate 211 applies downward pressure on the top of the piston rod 203, causing the piston rod 203 to retract into the connecting pipe inside the mounting base 201. At this time, the oil inside the connecting pipe acts as a transmission medium to push the oil inside the oil pipe 204, causing the telescopic rod 205 to extend with the curved plate 206 and the clamping piece 207, so that the clamping piece 207 can be exactly stuck in the reinforcement groove 212, thereby reinforcing the rod part of the temperature sensor 208.

[0042] When the water flows out of the tower along the inner portion of the water outlet pipe 1, the water flow is guided by the curved plate 206 when passing through the rod portion of the temperature sensor 208, thereby reducing the impact force on the rod portion. The curved plate 206 and the clamping piece 207 reinforce the rod portion of the temperature sensor 208, thereby further preventing the rod portion from shaking due to the impact force of the water flow.

[0043] When the temperature sensor 208 needs to be removed later, the threaded connection sleeve 210 is first rotated to slide upward along the rod body until the threaded connection sleeve 210 is separated from the threaded tube 202. As the threaded connection sleeve 210 rises, the circular pressure plate 211 rises accordingly. At the same time, the piston rod 203 loses the downward pressure and rises synchronously, causing the telescopic rod 205 to retract into the oil pipe 204. At this time, the arc plates 206 move away from each other and the clamping piece 207 leaves the reinforcement groove 212. At this time, the temperature sensor 208 can be pulled out.

[0044] When the temperature sensor 208 is pulled out, the sealing plate 4 loses the downward pressure and is reset by rotating upward through the torsion spring 5 until the sealing plate 4 is in contact with the sealing ring 3. At this time, even if the water out of the tower inside the outlet pipe body 1 continues to be transmitted, an upward force will only be provided from the bottom of the sealing plate 4, making the sealing plate 4 and the sealing ring 3 fit more tightly, thereby preventing the water out of the tower from leaking from the top opening of the threaded pipe 202 after the temperature sensor 208 is pulled out.
