Description

Technical Field

[0001] This utility model relates to the field of water pump waterproof cover technology, specifically a water pump rain cover with a circuit anti-detachment function. Background Technology

[0002] Water pumps are commonly used power devices in water supply systems. To extend their service life, rainproof and waterproof covers are often installed on the outside of the pump. Their main function is to prevent rainwater from directly contacting the pump and to avoid water entering the pump, which could cause short circuits or damage. To prevent the motor vibration from causing the wiring to come loose, existing water pump rainproof covers usually have a positioning structure on the cover. In addition, to prevent the contact parts of the positioning structure from not being able to dissipate heat effectively, a heat dissipation structure is also set on the positioning structure to effectively dissipate heat from the positioned wiring parts.

[0003] However, existing water pump rain covers with heat dissipation and anti-derailment functions usually use a single fan to accelerate the airflow, which then dissipates the heat generated by the circuitry. While this method can indeed dissipate heat from the circuitry section of the water pump rain cover to some extent, the already high air temperature in summer makes the accelerated airflow also quite hot. This means that it still cannot effectively dissipate heat from the circuitry section. If it cannot be effectively cooled, it will accelerate the aging rate of the circuitry.

[0004] To address this issue, we designed a water pump rain cover with anti-derailment function. Utility Model Content

[0005] The purpose of this utility model is to provide a water pump rain cover with a line anti-detachment function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a water pump rain cover with anti-derailment function, including a waterproof cover body with a fixing port on the front side, multiple combing ports on the rear side of the waterproof cover body, the combing ports being connected to the fixing port, and a clamping box provided on the rear side of the waterproof cover body, including...

[0007] A positioning box for a miniature fan is provided on the top of one side, and the number of such boxes is the same as the number of combing ports, and it is slidably connected to the clamping box.

[0008] The air vent is located on the top of one side of the positioning box and is flush with the miniature fan;

[0009] A conical cylinder is fixedly installed inside the positioning box and located diagonally below the air inlet, used to cool the airflow introduced into the positioning box;

[0010] The clamping component is installed on one side of the positioning box, and airflow channels and exhaust vents are respectively opened inside and on one side;

[0011] The guide tube is fixedly inserted between the positioning box and the clamping component. Multiple fixing plates are provided on one side of the waterproof cover body, and two positioning columns are symmetrically fixedly installed on one side of the fixing plates.

[0012] Furthermore, the interior of the waterproof cover body is provided with a serpentine tube, and the two ends of the serpentine tube are respectively fixedly connected to the conical cylinder and the guide pipe.

[0013] Furthermore, the positioning box is slidably inserted into the clamping box, and connecting rods are provided between adjacent positioning boxes. The system also includes a positioning assembly, including at least the following:

[0014] A pull rod is slidably inserted into one side of the clamping box and fixedly connected to one end of one of the positioning boxes. A spring is fixedly installed on one side of one of the positioning boxes, and the other end of the spring is fixedly connected to the inner wall of the clamping box.

[0015] Furthermore, a guide rod is inserted into the positioning box, and both ends of the guide rod are fixedly installed inside the clamping box.

[0016] Furthermore, a limiting port is provided at the bottom of the clamping box, the limiting port is connected to the interior of the clamping box, and the positioning box is slidably inserted into the limiting port.

[0017] Furthermore, the bottom of the waterproof cover body is provided with multiple heat dissipation vents, which are connected to the fixing port.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. By turning on the micro fan, the micro fan can accelerate the outside air to form an airflow that enters the conical cylinder through the air guide. Since the shape of the conical cylinder gradually narrows from top to bottom, the gas is compressed, its volume decreases, and the pressure drops. At the same time, the gas does work on the outside without heat replenishment, and the internal energy of the gas will decrease, resulting in a temperature drop. This can lower the airflow temperature. Meanwhile, the circuit will transfer heat to the clamping parts and even into the airflow channel. At this time, the cooled airflow can discharge the hot airflow in the airflow channel through the exhaust port, which can effectively achieve the effect of cooling the area of ​​the positioned circuit.

[0019] 2. By setting up a serpentine tube, the curved shape of the tube increases the distance of airflow. At this time, the wall of the serpentine tube exchanges heat with the airflow, causing the temperature to gradually decrease, which further improves the cooling effect of the airflow and thus further improves the heat dissipation effect of the circuit.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a water pump rain cover with anti-derailment function, including a waterproof cover body 1 with a fixing port 2 on the front side, multiple combing ports 3 on the rear side of the waterproof cover body 1, the combing ports 3 being connected to the fixing port 2, and a clamping box 4 provided on the rear side of the waterproof cover body 1, including...

[0027] A positioning box 5 for a miniature fan 6 is provided on the top of one side, and the number of such boxes is the same as that of the combing ports 3, and they are slidably connected to the clamping box 4.

[0028] The air vent 7 is located on the top of one side of the positioning box 5 and is flush with the miniature fan 6;

[0029] The conical cylinder 8 is fixedly installed inside the positioning box 5 and located diagonally below the air inlet 7, and is used to cool the airflow introduced into the positioning box 5.

[0030] The clamping component 9 is installed on one side of the positioning box 5, and an airflow channel 11 and an exhaust port 12 are respectively opened inside and on one side;

[0031] The guide tube 10 is fixedly inserted between the positioning box 5 and the clamping part 9. Multiple fixing plates 13 are provided on one side of the waterproof cover body 1, and two positioning posts 14 are symmetrically fixedly installed on one side of the fixing plate 13.

[0032] The positioning box 5 is slidably inserted into the clamping box 4, and a connecting rod 17 is provided between adjacent positioning boxes 5. The positioning assembly is also included, including at least the following:

[0033] Pull rod 19 is slidably inserted into one side of clamping box 4 and fixedly connected to one end of one of the positioning boxes 5. A spring 20 is fixedly installed on one side of one of the positioning boxes 5, and the other end of the spring 20 is fixedly connected to the inner wall of clamping box 4.

[0034] In practice, the waterproof cover body 1 is placed over the water pump body and the fixing port 2 is fitted onto the water pump, which can effectively protect the water pump from rain and help extend the service life of the water pump.

[0035] By setting multiple combing ports 3 to comb the lines on the water pump, before the line is inserted into the combing port 3, the pull rod 19 can be pulled to make the pull rod 19 drive multiple positioning boxes 5 to slide in the clamping box 4. When the line passes through the combing port 3, the pull rod 19 is released. At this time, the spring 20 can reset the positioning box 5 due to its own elasticity, and the line can be positioned between the clamping part 9 and the positioning post 14, thus achieving the effect of preventing the water pump line from getting off.

[0036] It is particularly important to note that, in order to effectively handle the heat generated by the circuit section positioned by the clamped component 9, the miniature fan 6 can be turned on. The miniature fan 6 accelerates the outside air to form an airflow that enters the conical cylinder 8 through the air guide port 7. Since the shape of the conical cylinder 8 gradually narrows from top to bottom, it can be approximated as an adiabatic expansion process. During this process, the gas is compressed, its volume decreases, and its pressure drops. At the same time, the gas does work on the outside without heat replenishment. According to the first law of thermodynamics, the internal energy of the gas will decrease, and the decrease in internal energy will cause the temperature to drop, thereby lowering the temperature of the airflow. Meanwhile, the circuit will transfer heat to the clamped component 9 and even into the airflow channel 11. At this time, the cooled airflow can also discharge the hot airflow in the airflow channel 11 through the exhaust port 12, which can effectively achieve the effect of cooling the area of ​​the positioned circuit.

[0037] See Figure 1-4 As shown, a serpentine tube 15 is provided inside the main body 1 of the waterproof cover, and the two ends of the serpentine tube 15 are fixedly connected to the conical cylinder 8 and the guide tube 10, respectively.

[0038] In specific implementation, based on the above implementation, after the airflow is cooled by the conical tube 8, it passes through the serpentine tube 15. Since the serpentine tube 15 is curved, it increases the distance of airflow. At this time, the wall of the serpentine tube 15 exchanges heat with the airflow, causing the temperature to gradually decrease, which can further improve the cooling effect of the airflow, thereby further improving the heat dissipation effect of the line.

[0039] See Figure 1-4 A guide rod 18 is inserted into the positioning box 5, and both ends of the guide rod 18 are fixedly installed in the clamping box 4. This can limit the sliding direction of the positioning box 5 and prevent the positioning box 5 from moving off course.

[0040] See Figure 1-4 The bottom of the clamping box 4 has a limiting port 16, which is connected to the inside of the clamping box 4. The positioning box 5 is slidably inserted into the limiting port 16.

[0041] It should be noted that the direction of the limiting port 16 is the same as the direction of the guide rod 18, which allows the positioning box 5 to slide normally within the clamping box 4 and avoids motion interference.

[0042] See Figure 1-4 The bottom of the waterproof cover body 1 has multiple heat dissipation vents 21, which are connected to the fixing port 2. By setting the heat dissipation vents 21, the heat generated by the water pump can be dissipated from the waterproof cover body 1, which helps to solve the problem of high temperature of the water pump.

[0043] In addition, it should be noted that anti-slip textures can be provided on the outer surface of the lever 19 to increase the friction between the user's hand and the lever 19, thereby helping to solve the problem of slippage when pulling the lever 19.

[0044] In addition, to facilitate the installation of the waterproof cover body 1 on the water pump, a positioning strip can be provided on the front side of the waterproof cover body 1, and screws can be threaded into the positioning strip so that the screws extend into the water pump housing, thus facilitating the installation of the waterproof cover body 1 and the water pump.

[0045] Working principle: When in use, first cover the water pump body with the waterproof cover body 1 and make the fixing port 2 fit and snap onto the water pump. By setting the heat dissipation port 21, the heat generated by the water pump can be dissipated from the waterproof cover body 1, which helps to solve the problem of high temperature of the water pump.

[0046] By setting multiple combing ports 3 to comb the lines on the water pump, before the line is inserted into the combing port 3, the pull rod 19 can be pulled to make the pull rod 19 drive multiple positioning boxes 5 to slide in the clamping box 4 along the direction set by the guide rod 18. When the line passes through the combing port 3, the pull rod 19 is released. At this time, the spring 20 can reset the positioning box 5 due to its own elasticity, and the line can be positioned between the clamping part 9 and the positioning post 14, thus achieving the effect of preventing the water pump line from getting off.

[0047] It is particularly important to note that, in order to effectively handle the heat generated by the circuit section positioned by the clamped component 9, the miniature fan 6 can be turned on. The miniature fan 6 accelerates the outside air to form an airflow that enters the conical cylinder 8 through the air guide port 7. Since the shape of the conical cylinder 8 gradually narrows from top to bottom, it can be approximated as an adiabatic expansion process. During this process, the gas is compressed, its volume decreases, and its pressure drops. At the same time, the gas does work on the outside without heat replenishment. According to the first law of thermodynamics, the internal energy of the gas will decrease, and the decrease in internal energy will cause the temperature to drop, thereby lowering the temperature of the airflow. Meanwhile, the circuit will transfer heat to the clamped component 9 and even into the airflow channel 11. At this time, the cooled airflow can also discharge the hot airflow in the airflow channel 11 through the exhaust port 12, which can effectively achieve the effect of cooling the area of ​​the positioned circuit.

[0048] Furthermore, after the airflow is cooled by the conical tube 8, it passes through the serpentine tube 15. Since the serpentine tube 15 is curved, it increases the distance the airflow travels. At this time, the wall of the serpentine tube 15 exchanges heat with the airflow, causing the temperature to gradually decrease, which can further improve the cooling effect of the airflow and thus further improve the heat dissipation effect of the circuit.
