[0002] The intelligent test pile is an indispensable device in the cathodic protection system. It is mainly used for the detection of cathodic protection effects and operating parameters. Generally, one test pile is set up every 1 to 2 km along the transmission pipeline. The test pile is designed as a multi-functional test pile, which is used for the detection of cathodic protection parameters. It is an indispensable device in pipeline management and maintenance. It is arranged along the line according to the test function. The test pile is used to detect the pipeline potential, current and insulation performance.
[0003] Cathodic protection intelligent test pile is an indispensable equipment in the multi-parameter data acquisition system of gas pipeline; the data collector is installed and works in the field working environment and is installed underground. In order to facilitate replacement, the battery and the data acquisition system are generally installed separately, that is, the shell and the battery box are designed to be detachable.
[0004] Although the cathodic protection intelligent test piles currently on the market use a design in which the battery box is separated from the main body, battery replacement is still cumbersome, and when located in a remote geographical location, manual data collection and transportation are required. At this time, the sealing and service life of the transmission port become particularly important. In addition, the test pile generates a lot of heat when working. General test piles use heat dissipation holes to dissipate heat through ventilation, but when in harsh environments, dust and sand in the air will enter the equipment and cause damage to the circuit system. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a cathodic protection intelligent test pile to solve the technical problem that the heat dissipation of traditional devices in harsh environments will affect the service life.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cathodic protection intelligent test pile, comprising a shell, a quick-release device is installed inside the shell, and a battery is installed inside the quick-release device, an electronic device is installed inside the shell above the battery, a pressurizing device is installed on the top of the shell, a one-way rotating device is installed on the top of the pressurizing device, and a fan blade is rotatably connected to the top of the one-way rotating device, and the pressurizing device includes a sealing shell, an air inlet, an air suction hole, an eccentric rotating wheel and a sealing block; the top of the shell is fixed with A sealing shell, one end of the inner bottom surface of the sealing shell is rotatably connected to an eccentric wheel, and an air inlet hole is opened on the bottom surface of the sealing shell on one side of the eccentric wheel, and an air suction hole is opened on the outer wall of the sealing shell close to the eccentric wheel but not on the same side of the air inlet hole, a plurality of sealing blocks are slidably penetrated through the outer wall of the eccentric wheel, and the pressurizing device also includes a second limit spring and a clamping block, a clamping block is fixed to the tail end of each sealing block, and the clamping block is located inside the eccentric wheel, a second limit spring is connected between every two relative sealing blocks, and each second limit spring does not interfere with each other.
[0007] By adopting the above technical solution, the rotation of the fan blades drives the eccentric wheel to rotate, and the first limit spring pushes the active end of the sealing block to be in close contact with the inside of the sealing shell at all times. When the sealed cavity formed by the sealing shell passes through the air intake hole, the volume of the sealed cavity gradually decreases and finally the gas is squeezed into the inside of the main body through the air intake hole, and this cycle repeats over and over again, thereby increasing the air pressure at the electronic components in the outer shell. Under high pressure conditions, the density of the gas is relatively high, which causes the air molecules to more closely surround the surface of the object, increasing the mechanism of heat conduction and heat convection, and heat is more easily exchanged and balanced between the surface of the object and the surrounding air, making the heat distribution more even, which helps to prevent local accumulation of heat inside the object and improves the heat dissipation efficiency. Moreover, under high pressure conditions, due to the low gas density, the breakdown voltage of the electronic components will increase, which means that under the same voltage, the electronic components are not prone to breakdown, and the probability of component damage or performance degradation is reduced.
[0008] The utility model is further configured as follows: the quick-release device includes a sliding shell, a sliding groove, a slider, a battery shell, a top plate and a first limit spring; the outer wall of the shell is sleeved with a sliding shell, and a top plate is connected in the middle of both sides of the inner wall of the sliding shell, a first limit spring is connected between the top plate and the inner bottom surface of the shell, and the top surface of the top plate contacts the battery shell, sliders are fixed on both sides of the battery shell, sliding grooves are opened on both sides of the inner wall of the shell, and the slider is slidably connected to the inner wall of the shell through the sliding grooves on both sides of the shell.
[0009] By adopting the above technical solution, when the sliding shell is in the closed state, the battery is in a protected state, the connection port of the electronic device is sealed, the sliding shell is pulled downward, the top plate presses down the first limit spring and the slider drives the battery shell to descend along the slide groove, the battery shell stops after descending to the end of the slide groove, and the top plate is separated from the bottom surface of the battery shell. Since the slider is not in the center position of both sides of the battery shell, the battery shell will drive the battery to tilt along the slider, which is convenient for removing and replacing the battery.
[0010] The utility model is further configured as follows: the one-way rotating device includes a first rotating shaft, a second rotating shaft, a one-way face gear, a limiting cylinder, a fixed shell and a third limiting spring, the top surface of the sealing shell is installed with a fixed shell, the interior of the fixed shell is penetrated by the first rotating shaft and the second rotating shaft, and the first rotating shaft and the second rotating shaft are coaxial, the first rotating shaft and the second rotating shaft are connected to the one-way face gear at one end facing inward, and the two one-way face gears cooperate with each other, the first rotating shaft and the second rotating shaft outer wall one end facing inward both rotate to penetrate the limiting cylinder, the bottom surface of the inner wall of the fixed shell contacts with the bottom surface of the limiting cylinder, the top surface of the one-way face gear connected to the first rotating shaft and the top surface of the inner wall of the limiting cylinder are rotatably connected with the third limiting spring, the end of the first rotating shaft that penetrates the top surface of the fixed shell is connected to the fan blade, and the one-way rotating The rotating device also includes a third rotating shaft, a meshing gear, a ratchet mechanism and a meshing block, the top surface of the eccentric rotating wheel is connected to the meshing block, and the axis of the meshing block rotates through the top surface of the sealing shell, the internal rotation of the fixed shell rotates through the third rotating shaft, and the top surface of the third rotating shaft is connected to the ratchet mechanism, the outer wall of the ratchet mechanism is meshed with the first rotating shaft, the bottom ends of the second rotating shaft and the third rotating shaft are both connected to the meshing gear, and each meshing gear is meshed with the inner wall of the meshing block, the ratchet mechanism includes a ratchet inner wheel, a pawl, a fourth limit spring and a ratchet outer wheel, the top surface of the third rotating shaft is connected to the ratchet inner wheel, and the outer wall of the ratchet inner wheel is rotatably sleeved with a ratchet outer wheel, the outer wall of the ratchet inner wheel is rotatably connected to a pawl that cooperates with the ratchet outer wheel, and a fourth limit spring is connected between the pawl and the ratchet inner wheel.
[0011] By adopting the above technical scheme, since the wind in nature blows in all directions, the rotation direction of the eccentric wheel to drive the sealing block to pressurize is set to be positive. When the fan blade rotates in the positive direction, the pawl contacts the inclined surface of the inner wall of the ratchet outer wheel, and the ratchet inner wheel does not rotate, while the vertical surfaces of the two one-way face gears contact, and the first rotating shaft drives the second rotating shaft to rotate, and the meshing gear at the bottom end of the second rotating shaft meshes with the inner wall of the meshing block, and finally the meshing block drives the eccentric wheel to rotate. When the fan blade rotates in the reverse direction, the inclined surfaces of the two one-way face gears contact, and the second rotating shaft does not rotate.

[0013] The utility model drives the eccentric rotating wheel to rotate by the rotation of the fan blade, and the first limit spring pushes the movable end of the sealing block to be in close contact with the inside of the sealing shell at all times. After the sealing cavity composed of the sealing shell passes through the air intake hole, the volume of the sealing cavity gradually decreases, and finally the gas is squeezed into the inside of the main body through the air intake hole, and the cycle is repeated to increase the air pressure at the electronic device in the shell. Under high pressure environment, the density of the gas is relatively high, which will cause the air molecules to surround the surface of the object more closely, increase the mechanism of heat conduction and heat convection, and heat is more easily exchanged and balanced between the surface of the object and the surrounding air, so that the heat distribution is more uniform, which helps to prevent the local accumulation of heat inside the object and improve the heat dissipation efficiency. In addition, under high pressure environment, due to the low gas density, the breakdown voltage of the electronic device will be increased, which means that under the same voltage, the electronic device is not prone to breakdown, and the probability of device damage or performance degradation is reduced. Since the wind in nature blows in all directions, the rotation direction of the eccentric rotating wheel to drive the sealing block to pressurize is set to be positive. When the rotation direction of the fan blade is positive, the ratchet pawl is in contact with the inclined surface of the inner wall of the outer wheel of the ratchet wheel. When the first rotating shaft is in contact with the second rotating shaft, the inner wheel of the ratchet wheel does not rotate, while the vertical surfaces of the two one-way face gears are in contact, and the first rotating shaft drives the second rotating shaft to rotate, and the meshing gear at the bottom of the second rotating shaft meshes with the inner wall of the meshing block, and finally the meshing block drives the eccentric rotating wheel to rotate. When the fan blade rotates in the reverse direction, the inclined surfaces of the two one-way face gears are in contact, and the second rotating shaft does not rotate. At this time, the pawl cooperates with the vertical surface of the inner wall of the ratchet outer wheel, and the inner wheel of the ratchet wheel drives the third rotating shaft to convert to forward rotation, and the meshing gear at the bottom of the third rotating shaft meshes with the inner wall of the meshing block, and finally the meshing block drives the eccentric rotating wheel to rotate. The wheel rotates, so no matter what the rotation direction of the fan is, the final rotation direction output to the eccentric wheel is always positive; when the sliding shell is closed, the battery is in a protected state, and the connection port of the electronic device is sealed, the sliding shell is pulled downward, the top plate presses down the first limit spring to descend, and the slider drives the battery shell to descend along the slide slot, and the battery shell stops after descending to the end of the slide slot, and the top plate is separated from the bottom surface of the battery shell. Since the slider is not in the center position of both sides of the battery shell, the battery shell will drive the battery to tilt along the slider, which is convenient for taking out and replacing the battery.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0023] The following describes an embodiment of the utility model based on its overall structure.
[0024] A cathodic protection intelligent test pile, such as Figure 1-7As shown, it includes a shell 1, a quick release device 4 is installed inside the shell 1, and a battery 3 is installed inside the quick release device 4, an electronic device 2 is installed above the battery 3 inside the shell 1, and the electronic device 2 is composed of a circuit board, data acquisition, data storage, data connection port, etc., a pressurizing device 5 is installed on the top of the shell 1, a one-way rotating device 6 is installed on the top of the pressurizing device 5, and a fan blade 7 is rotatably connected to the top of the one-way rotating device 6, and a sealing shell 501 is fixed on the top of the shell 1, and the sealing shell 501 is inside. An eccentric rotating wheel 504 is rotatably connected to one end of the bottom surface of the sealing shell 501, and an air inlet hole 502 is opened on the bottom surface of the sealing shell 501 on one side of the eccentric rotating wheel 504, and an air suction hole 503 is opened on the outer wall of the sealing shell 501 close to the eccentric rotating wheel 504 and not on the same side of the air inlet hole 502. A plurality of sealing blocks 505 are slidably penetrated through the outer wall of the eccentric rotating wheel 504, and a clamping block 507 is fixed at the tail end of each sealing block 505, and the clamping block 507 is located inside the eccentric rotating wheel 504, and a first clamping block 507 is connected between every two opposing sealing blocks 505. There are two limit springs 506, and each second limit spring 506 does not interfere with each other. The rotation of the fan blade 7 drives the eccentric wheel 504 to rotate, and the first limit spring 406 pushes the active end of the sealing block 505 to be in close contact with the inside of the sealing shell 501 at all times. When the sealed cavity formed by the sealing shell 501 passes through the air intake hole 503, the volume of the sealed cavity gradually decreases and finally the gas is squeezed into the inside of the main body through the air inlet hole 502, and the cycle repeats to increase the air pressure at the electronic device 2 in the shell 1. Under high pressure, the density of the gas is relatively high, which will cause the air molecules to surround the surface of the object more tightly, increasing the mechanism of heat conduction and heat convection, and heat is more easily exchanged and balanced between the surface of the object and the surrounding air, making the heat distribution more uniform, which helps to prevent local accumulation of heat inside the object and improves the heat dissipation efficiency. In addition, under high pressure, due to the low gas density, the breakdown voltage of the electronic device 2 will increase, which means that under the same voltage, the electronic device 2 is not prone to breakdown, and the probability of device damage or performance degradation is reduced.
[0025] The outer wall of the housing 1 is sleeved with a sliding housing 401, and a top plate 405 is connected in the middle of both sides of the inner wall of the sliding housing 401, a first limit spring 406 is connected between the top plate 405 and the inner bottom surface of the housing 1, and the top surface of the top plate 405 contacts the battery housing 404, and sliders 403 are fixed on both sides of the battery housing 404, and the sliders 403 are connected to the inner wall of the housing 1 through the sliding grooves 402 provided on both sides of the inner wall of the housing 1. When the sliding housing 401 is closed, the battery 3 is in a protected state. The connection port of the electronic device 2 is sealed, and the sliding shell 401 is pulled downward, and the top plate 405 presses down the first limit spring 406 to move downward, and the slider 403 drives the battery shell 404 to move downward along the slide groove 402. The battery shell 404 stops after it moves downward to the end of the slide groove 402, and the top plate 405 is separated from the bottom surface of the battery shell 404. Since the slider 403 is not at the center position on both sides of the battery shell 404, the battery shell 404 will drive the battery to tilt along the slider 403, which is convenient for removing and replacing the battery.
[0026] A fixed shell 608 is installed on the top surface of the sealing shell 501, and the first rotating shaft 601 and the second rotating shaft 602 are penetrated inside the fixed shell 608, and the first rotating shaft 601 and the second rotating shaft 602 are coaxial, and the inward ends of the first rotating shaft 601 and the second rotating shaft 602 are both connected to a one-way face gear 604, and the two one-way face gears 604 cooperate with each other, and the inward ends of the outer walls of the first rotating shaft 601 and the second rotating shaft 602 are both rotated to penetrate the limiting cylinder 607, and the bottom surface of the inner wall of the fixed shell 608 contacts the bottom surface of the limiting cylinder 607, and the third limiting spring 609 is rotatably connected between the top surface of the one-way face gear 604 connected to the first rotating shaft 601 and the top surface of the inner wall of the limiting cylinder 607. The first rotating shaft 601 passes through one end of the top surface of the fixed shell 608 and is connected to the fan blade 7. The top surface of the eccentric rotating wheel 504 is connected to the meshing block 610, and the axis of the meshing block 610 rotates and passes through the top surface of the sealing shell 501. The internal rotation of the fixed shell 608 passes through the third rotating shaft 603, and the top surface of the third rotating shaft 603 is connected to the ratchet mechanism 605. The outer wall of the ratchet mechanism 605 is meshed with the first rotating shaft 601. The bottom ends of the second rotating shaft 602 and the third rotating shaft 603 are both connected to the meshing gear 606, and each meshing gear 606 is meshed with the inner wall of the meshing block 610. The top surface of the third rotating shaft 603 is connected to the ratchet inner wheel 6051, and the outer wall of the ratchet inner wheel 6051 is meshed with the first rotating shaft 601. The wall rotating sleeve is provided with a ratchet outer wheel 6054, and the outer wall of the ratchet inner wheel 6051 is rotatably connected to a ratchet pawl 6052 that cooperates with the ratchet outer wheel 6054, and a fourth limit spring 6053 is connected between the ratchet pawl 6052 and the ratchet inner wheel 6051. Since the wind in nature blows in all directions, the rotation direction of the eccentric rotating wheel 504 to drive the sealing block 505 to pressurize is set to be positive. When the rotation direction of the fan blade 7 is positive, the ratchet pawl 6052 contacts the inclined surface of the inner wall of the ratchet outer wheel 6054, the ratchet inner wheel 6051 does not rotate, and the vertical surfaces of the two one-way face gears 604 contact, and the first rotating shaft 601 drives the second rotating shaft 602 to rotate, and through the bottom end of the second rotating shaft 602 The meshing gear 606 meshes with the inner wall of the meshing block 610, and finally the meshing block 610 drives the eccentric wheel 504 to rotate. When the fan blade 7 rotates in the reverse direction, the inclined surfaces of the two one-way face gears 604 contact, and the second shaft 602 does not rotate. At this time, the pawl 6052 cooperates with the vertical surface of the inner wall of the ratchet outer wheel 6054, and the ratchet inner wheel 6051 drives the third shaft 603 to convert into forward rotation, and the meshing gear 606 at the bottom end of the third shaft 603 meshes with the inner wall of the meshing block 610, and finally the meshing block 610 drives the eccentric wheel 504 to rotate. In this way, no matter what the rotation direction of the fan is, the final rotation direction output to the eccentric wheel 504 is always forward.
[0027] Working principle: When the sliding shell 401 is closed, the battery 3 is in a protected state, the connection port of the electronic device 2 is sealed, the rotation of the fan blade 7 drives the eccentric wheel 504 to rotate, and the first limit spring 406 pushes the movable end of the sealing block 505 to be in close contact with the inside of the sealing shell 501 at all times. When the sealed cavity formed by the sealing shell 501 passes through the air intake hole 503, the volume of the sealed cavity gradually decreases and finally the gas is squeezed into the main body through the air inlet hole 502, and the cycle repeats to increase the air pressure at the electronic device 2 in the shell 1. Under high-pressure environment, the density of the gas is relatively high, which will cause the air molecules to surround the surface of the object more tightly, increase the mechanism of heat conduction and heat convection, and heat is more easily exchanged and circulated between the surface of the object and the surrounding air. The balance makes the heat distribution more uniform, which helps to prevent the local accumulation of heat inside the object and improves the heat dissipation efficiency. In addition, under high pressure environment, due to the low gas density, the breakdown voltage of the electronic device 2 will increase, which means that under the same voltage, the electronic device 2 is not prone to breakdown, and the probability of device damage or performance degradation is reduced. Since the wind in nature blows in all directions, the rotation direction of the eccentric wheel 504 to drive the sealing block 505 to apply pressure is set to be positive. When the fan blade 7 rotates in the positive direction, the pawl 6052 contacts the inclined surface of the inner wall of the ratchet outer wheel 6054. When the ratchet outer wheel 6054 rotates, the pawl 6052 retreats, so the ratchet inner wheel 6051 does not rotate, and the vertical surfaces of the two one-way face gears 604 are in contact, and the third limit The spring 609 allows the two one-way face gears 604 to be in close contact, the first rotating shaft 601 drives the second rotating shaft 602 to rotate, and the meshing gear 606 at the bottom end of the second rotating shaft 602 meshes with the inner wall of the meshing block 610, and finally the meshing block 610 drives the eccentric rotating wheel 504 to rotate. When the fan blade 7 rotates in the reverse direction, the fourth limit spring 6053 lifts the pawl 6052, so that the pawl 6052 is fixed to the vertical surface of the inner wall of the ratchet outer wheel 6054, and the ratchet inner wheel 6051 drives the third rotating shaft 603 to convert to forward rotation, and the meshing gear 606 at the bottom end of the third rotating shaft 603 meshes with the inner wall of the meshing block 610, and finally the meshing block 610 drives the eccentric rotating wheel 504 to rotate, and the meshing gear 606 at the bottom end of the second rotating shaft 602 meshes with the inner wall of the meshing block 610. 06 is driven by the meshing block 610 to rotate forward, and the first rotating shaft is in reverse rotation. At this time, due to the contact of the inclined surfaces of the two one-way face gears 604, the lateral force of the one-way face gear 604 at the bottom end of the first rotating shaft 601 and the one-way face gear 604 at the top end of the second rotating shaft 602 is offset when they rotate, and the first rotating shaft 601 and the second rotating shaft 602 do not affect each other. In this way, no matter what the rotation direction of the fan is, the final rotation direction output to the eccentric wheel 504 is always forward. When it is necessary to replace the battery and collect data, pull the sliding shell 401 downward to expose the connection port, and the top plate 405 presses down the first limit spring 406 to descend. The slider 403 drives the battery shell 404 to descend along the slide groove 402, and the battery shell 404 stops after descending to the end of the slide groove 402.The top plate 405 is separated from the bottom surface of the battery shell 404. Since the slider 403 is not located at the center of both sides of the battery shell 404, the battery shell 404 will drive the battery to tilt along the slider 403, making it easier to remove and replace the battery.
