Description

Technical Field

[0001] This utility model belongs to the technical field of automotive cooling system accessories, and in particular relates to a coolant reservoir outlet capable of leak detection. Background Technology

[0002] The coolant reservoir is a crucial component of a car's cooling system, used to store coolant and balance system pressure. Its outlet connects to components such as the engine via pipes, ensuring coolant circulation for heat dissipation. The sealing performance of the outlet directly affects the normal operation of the cooling system; leaks can lead to insufficient coolant, engine overheating, and even mechanical failure.

[0003] In existing equipment, most of the outlets and pipes are sealed with rubber sealing rings. Although this can prevent leakage to a certain extent, it lacks active detection function. It is difficult to detect leakage in the early stage. It is often not detected until the coolant is significantly reduced or the system alarms, which delays the maintenance time. There are no emergency protection measures after leakage, and the leakage condition will continue to deteriorate, increasing the risk of failure. Therefore, we propose a coolant tank outlet that can detect leakage. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water tank outlet capable of leak detection. By installing a detection device in the outlet pipe, a leak ring is used to collect the leaked liquid, which is then guided into a water collection tank through a guide pipe. The leak causes the float to rise, which in turn triggers the alarm to promptly alert the user to the leak. This solves the problems of existing equipment where leaks are difficult to detect in a timely manner, lack of emergency protection, and easy failure of the detection device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cooling water tank outlet capable of leak detection, comprising: a liquid storage chamber and a mounting bracket, the mounting bracket being fixedly connected to the side of the liquid storage chamber, a return water pipe being fixedly connected to the top of the liquid storage chamber, an outlet water pipe being fixedly connected to the side of the liquid storage chamber, and a detection device being provided on the circumferential surface of the outlet water pipe.

[0007] The detection device includes a leakage ring, the inner circumferential surface of which is fixedly connected to one end of a water outlet pipe. A guide pipe is fixedly connected to the circumferential surface of the water outlet pipe. A water collection tank is fixedly connected to one end of the guide pipe. A float is provided at the bottom of the inner wall of the water collection tank. A transmission rod is fixedly connected to the top of the float. A support plate is fixedly connected to one end of the transmission rod. A trigger rod is fixedly connected to the top of the support plate. A device box is fixedly connected to the side of the liquid storage chamber. An alarm is fixedly connected to the bottom of the inner wall of the device box. A trigger switch is provided inside the device box.

[0008] Furthermore, the bottom of the trigger switch is located on the displacement trajectory of the top of the trigger rod, and the circumferential surface of the trigger rod is slidably connected to the bottom of the device box. The positions of the trigger switch and the trigger rod are matched to ensure that the trigger rod can accurately contact the trigger switch when there is leakage, and quickly start the alarm. The sliding connection between the trigger rod and the device box ensures that the triggering action is stable and reliable, and reduces false triggering.

[0009] Furthermore, there are two transmission rods, which are symmetrical to each other along the vertical central axis of the float. The circumferential surface of the trigger rod passes through and is slidably connected to the top of the inner wall of the water collection tank. The two symmetrical transmission rods push the support plate synchronously from both sides to avoid triggering deviation caused by unilateral force, enhance the stability of the detection response, and improve the overall load-bearing capacity of the structure.

[0010] Furthermore, the diameter of the float is equal to the inner wall diameter of the water collection tank, and the side of the float is slidably connected to the inner wall of the water collection tank. The matching design between the float and the water collection tank allows the float to rise and fall precisely according to the leakage volume, avoiding detection delays caused by gaps, ensuring a linear correspondence between the leakage volume and the float displacement, and improving detection accuracy.

[0011] Furthermore, a protective device is provided on the top of the trigger switch. The protective device includes a spring. The spring is fixedly connected to the top of the trigger switch. One end of the spring is fixedly connected to a base. A bracket is fixedly connected to the circumferential surface of the base. A valve switch is provided at the bottom of the base. A control valve is fixedly connected to the circumferential surface of the water outlet pipe.

[0012] Furthermore, an auxiliary trigger rod is fixedly connected to the top of the trigger switch, and the bottom of the valve shut-off switch is located on the displacement trajectory of the auxiliary trigger rod. When the leakage is too large, the auxiliary trigger rod and the spring trigger the valve shut-off action to achieve flow interception protection and reduce leakage loss.

[0013] Furthermore, the number of brackets is set to four, and they are arranged in a circumferential array on the circumferential surface of the base. The displacement stroke of the top of the auxiliary trigger rod is equal to the height of the inner wall of the water collection tank. The four circumferentially arrayed brackets reinforce the base and fix it, ensuring that the valve shut-off switch is installed stably. The stroke design of the auxiliary trigger rod ensures that the valve shut-off can be reliably triggered when the leakage reaches the critical value, avoiding functional failure caused by insufficient stroke.

[0014] This utility model has the following beneficial effects:

[0015] This invention achieves accurate leak detection and rapid alarm through a detection device. The leak ring collects the leaking liquid from the outlet pipe and guides it into the collection tank through the guide pipe. The float rises with the amount of leakage and drives the trigger rod to move upward through the transmission rod. The cooperation between the trigger rod and the trigger switch can quickly activate the alarm. The design of two symmetrical transmission rods and float adapted to the collection tank ensures a stable and unbiased detection process, greatly improving the timeliness and accuracy of leak detection and preventing leak problems from being overlooked.

[0016] This invention achieves linkage protection after leakage through a protective device. Especially when the leakage is large, when the trigger switch is triggered, the auxiliary trigger rod moves upward synchronously. When the leakage is large and the float rises significantly, the trigger switch compresses the spring and touches the valve shut-off switch, causing the control valve to close the outlet pipe. The buffering effect of the spring can prevent accidental valve closure when there is a small amount of leakage. The flow is only triggered when the leakage reaches a certain level, minimizing the loss caused by leakage.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 The present invention is a cooling water kettle outlet capable of leak detection, comprising: a liquid storage chamber 1 and a mounting bracket 2, the mounting bracket 2 is fixedly connected to the side of the liquid storage chamber 1, a return water pipe 3 is fixedly connected to the top of the liquid storage chamber 1, a water outlet pipe 4 is fixedly connected to the side of the liquid storage chamber 1, and a detection device 5 is provided on the circumferential surface of the water outlet pipe 4.

[0028] The detection device 5 includes a leakage ring 501. The inner circumferential surface of the leakage ring 501 is fixedly connected to one end of the water outlet pipe 4. The circumferential surface of the water outlet pipe 4 is fixedly connected to a guide pipe 502. One end of the guide pipe 502 is fixedly connected to a water collection tank 503. A float 504 is provided at the bottom of the inner wall of the water collection tank 503. A transmission rod 505 is fixedly connected to the top of the float 504. A support plate 506 is fixedly connected to one end of the transmission rod 505. A trigger rod 507 is fixedly connected to the top of the support plate 506. A device box 508 is fixedly connected to the side of the liquid storage chamber 1. An alarm 509 is fixedly connected to the bottom of the inner wall of the device box 508. A trigger switch 510 is provided inside the device box 508.

[0029] As shown in the figure, the bottom of the trigger switch 510 is located on the displacement trajectory of the top of the trigger rod 507. The circumferential surface of the trigger rod 507 is slidably connected to the bottom of the device box 508. The positions of the trigger switch 510 and the trigger rod 507 are matched to ensure that the trigger rod 507 can accurately contact the trigger switch 510 when there is leakage, and quickly start the alarm. The sliding connection between the trigger rod 507 and the device box 508 ensures that the triggering action is stable and reliable and reduces false triggering.

[0030] As shown in the figure, there are two transmission rods 505, which are symmetrical to each other along the vertical central axis of the float 504. The circumferential surface of the trigger rod 507 passes through and is slidably connected to the top of the inner wall of the water collection tank 503. The two symmetrical transmission rods 505 push the support plate 506 synchronously from both sides to avoid triggering deviation caused by unilateral force, enhance the stability of the detection response, and improve the overall load-bearing capacity of the structure.

[0031] As shown in the figure, the diameter of the float 504 is equal to the inner wall diameter of the water collection tank 503. The side of the float 504 is slidably connected to the inner wall of the water collection tank 503. The matching design between the float 504 and the water collection tank 503 enables the float 504 to rise and fall precisely with the leakage volume, avoiding detection delay caused by gaps, ensuring a linear correspondence between the leakage volume and the displacement of the float 504, and improving detection accuracy.

[0032] As shown in the figure, a protective device 6 is provided on the top of the trigger switch 510. The protective device 6 includes a spring 601. The spring 601 is fixedly connected to the top of the trigger switch 510. One end of the spring 601 is fixedly connected to a base 602. A bracket 603 is fixedly connected to the circumferential surface of the base 602. A control valve switch 604 is provided at the bottom of the base 602. A control valve 7 is fixedly connected to the circumferential surface of the water outlet pipe 4.

[0033] As shown in the figure, an auxiliary trigger rod 605 is fixedly connected to the top of the trigger switch 510, and the bottom of the valve shut-off switch 604 is located on the displacement trajectory of the auxiliary trigger rod 605. When the leakage is too large, the auxiliary trigger rod 605 and the spring 601 trigger the valve shut-off action to achieve flow interception protection and reduce leakage loss.

[0034] As shown in the figure, there are four brackets 603 arranged in a circumferential array on the circumferential surface of the base 602. The displacement stroke of the top of the auxiliary trigger rod 605 is equal to the height of the inner wall of the water collection tank 503. The four circumferentially arrayed brackets 603 reinforce the base 602 and ensure the stable installation of the valve switch 604. The stroke design of the auxiliary trigger rod 605 ensures that the valve can be reliably triggered when the leakage reaches the critical value, avoiding functional failure caused by insufficient stroke.

[0035] One specific application of this embodiment is as follows: In the engine cooling system of an automobile, if a slight leak occurs at the outlet pipe 4 and the interface due to aging of the seal during engine operation, the leaking coolant will first be intercepted by the leak ring 501, and then flow into the water tank 503 through the guide pipe 502. As the liquid level in the water tank 503 rises, the float 504 is lifted accordingly, and the support plate 506 is moved upward through the transmission rod 505. The trigger rod 507 passes through the top of the water tank 503 and the bottom of the device box 508, and touches the trigger switch 510. At this time, the alarm 509 in the device box 508 immediately sounds a buzzer to remind the driver that there is a leak in the cooling system.

[0036] If the leakage suddenly increases, the liquid level in the water collection tank 503 rises rapidly. The float 504 drives the trigger rod 507 to continuously push the trigger switch 510 upward. The trigger switch 510 compresses the spring 601 at the top and pushes the auxiliary trigger rod 605 upward. When the auxiliary trigger rod 605 touches the valve shut-off switch 604, the control valve 7 on the water outlet pipe 4 quickly closes, cutting off the coolant supply and preventing a large amount of leakage. During this process, the four circumferentially arrayed brackets 603 firmly support the base 602, ensuring that the valve shut-off switch 604 does not shift. The stroke design of the auxiliary trigger rod 605, which is height-matched with the inner wall of the water collection tank 503, ensures that the valve shut-off action is accurately triggered when the leakage reaches the critical value.
