[0004] Currently, metering boxes on the market require protective devices during use. However, existing protective devices typically include a protective cabinet and a protective door, with ventilation holes on both sides of the cabinet. The cabinet and door protect the metering box inside. Since the ventilation holes are mostly open, rainwater can enter the cabinet through them during severe weather, damaging the metering box and affecting the effectiveness of the protective device. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for a metering box, so as to solve the problem mentioned in the background art that when the existing protective devices encounter severe weather, rainwater and other substances will enter the protective cabinet through the holes and slots, causing damage to the metering box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a metering box, comprising a protective device body and a blocking assembly for the metering box; the protective device body includes a cabinet for accommodating the metering box, a cabinet door, a top plate, a heat dissipation groove, and a fan; the cabinet door is hinged to the cabinet body via a hinge; the top plate is connected to the top surface of the cabinet body via several support rods; several heat dissipation grooves are symmetrically arranged in a linear array on both sides of the cabinet body; the fan is detachably mounted on the top surface of the cabinet body via a first bolt, and the rotation direction of the fan is from the outside to the inside; the blocking assembly is arranged in the heat dissipation groove; the blocking assembly includes a rotating rod, a blocking plate, a limiting groove, and a limiting pin; the rotating rod is rotatably connected to the inner wall of the heat dissipation groove via a rotating shaft; the blocking plate is sleeved on the rotating rod, and the blocking plate is made of a lightweight rigid material; at least one limiting groove is provided in the heat dissipation groove; the limiting pin slides through the limiting groove and is fixedly connected to the blocking plate.

[0007] Preferably, the protective device body further includes a control unit and a temperature sensor; the control unit is detachably mounted on the outer side of the cabinet via a second bolt; the temperature sensor is detachably mounted on the inner side of the cabinet via a third bolt; the output end of the control unit is electrically connected to the input end of the fan via a wire; the temperature sensor transmits the collected data to the control unit's data processing module via an electrical signal, and the control unit controls the fan.

[0008] Preferably, the baffle plate has an inclined structure, the structural opening formed between two adjacent baffle plates is oriented downwards, the high end of the baffle plate is an arc-shaped surface, and the height of the baffle plate is greater than the height of the inner wall of the heat dissipation groove.

[0009] Preferably, the limiting groove is an arc-shaped structure, and the center of the limiting groove is located on the axis of the rotating rod.

[0010] Preferably, it also includes a reinforcing component; part of the reinforcing component is disposed on the heat dissipation groove, and another part is disposed on the baffle plate.

[0013] Preferably, the reinforcing groove has a wave-shaped structure, and the shape of the reinforcing groove is adapted to the shape of the reinforcing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a blocking component, allows the metering box to be installed inside the cabinet after the cabinet door is opened. When the door is closed, a temperature sensor monitors the temperature inside the cabinet in real time. When heat dissipation is needed for the metering box, the temperature sensor, in conjunction with the control unit, activates the fan, causing airflow from the outside to the inside. This airflow creates an airflow around the cabinet door, increasing the internal air pressure and pushing the blocking plate. The blocking plate rotates, causing the rotating rod to rotate within the heat dissipation groove via a rotating shaft. This causes the limiting pin to slide within the limiting groove, preventing the inclined surface of the blocking plate from contacting the inclined surface of the contact groove until the limiting pin slides to the inner wall of the limiting groove. At this point, the blocking plate rotates to its maximum extent, allowing the airflow to carry heat through the space between the blocking plate and the heat dissipation groove and discharge it into the outside. Compared to existing technologies, this utility model has a simple and reasonable structure and ingenious design. By utilizing the rotation of the fan to create an airflow around the surrounding air, which then pushes the blocking plate, it not only ensures good heat dissipation but also prevents rainwater from entering the cabinet through the heat dissipation groove, thereby improving the protection of the metering box.

[0016] 2. This utility model, by setting up reinforcing components, including reinforcing grooves and reinforcing blocks, facilitates an increase in the contact area between the airflow and the baffle plate, thereby improving the effect of the airflow on the baffle plate and making it easier for the baffle plate to rotate under force. Since the contact groove is a right-angled triangular structure, it facilitates the fit between the inclined surface of the baffle plate and the inclined surface of the contact groove. Since the reinforcing groove is a wave-shaped structure, it facilitates the self-guiding effect of the contact between the reinforcing block and the inner wall of the reinforcing groove.

[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 Figures 1 to 6 This utility model provides a technical solution: a protective device for a metering box, including a protective device body 1 and a blocking component 2 for the metering box; the protective device body 1 includes a cabinet 101 for accommodating the metering box, a cabinet door 102, a top plate 103, a heat dissipation groove 104, a fan 105, a control unit 106, and a temperature sensor 107; the cabinet door 102 is hinged to the cabinet body 101; the top plate 103 is connected to the top surface of the cabinet body 101 by several support rods; several heat dissipation grooves 104 are symmetrically arranged in a linear array on both sides of the cabinet body 101; the fan 105 is detachably mounted on the top surface of the cabinet body 101 by a first bolt, and the rotation direction of the fan 105 is to blow air from the outside to the inside; the top of the cabinet body 101... A dustproof screen is installed on the surface of the cabinet 101 by screws, and the dustproof screen is located directly above the fan 105; the control unit 106 is detachably installed on the outer side of the cabinet 101 by a second bolt; the temperature sensor 107 is detachably installed on the inner side of the cabinet 101 by a third bolt. The control unit 106, the temperature sensor 107, and the fan 105 are usually connected by an electrical signal between the output terminal of the temperature sensor 107 and the input terminal of the data processing module of the control unit 106. The output terminal of the control unit 106 is electrically connected to the input terminal of the fan 105 by a wire. The temperature sensor 107 transmits the collected data to the data processing module of the control unit 106 through an electrical signal, and the control unit 106 controls the fan 105.

[0027] The blocking assembly 2 is arranged inside the heat dissipation groove 104; the blocking assembly 2 includes a rotating rod 201, a blocking plate 202, a limiting groove 203, and a limiting pin 204; the rotating rod 201 is rotatably connected to the inner wall of the heat dissipation groove 104 via a rotating shaft; the blocking plate 202 is fixedly connected to the rotating rod 201, and the blocking plate 202 is made of a lightweight rigid material, such as carbon fiber composite material; two limiting grooves 203 are symmetrically opened on both sides of the inner wall of the heat dissipation groove 104; the limiting pin 204 slides through the limiting groove 203 and... It is fixedly connected to the baffle plate 202; the baffle plate 202 has an inclined structure, and the structure opening formed between two adjacent baffle plates 202 is set downward. The high end of the baffle plate 202 is an arc surface, and the height dimension of the baffle plate 202 is greater than the height dimension of the inner wall of the heat dissipation groove 104, so as to facilitate the baffle plate 202 to block the heat dissipation groove 104; the limiting groove 203 has an arc structure, and the center of the limiting groove 203 is located on the axis of the rotating rod 201, so as to facilitate the limitation of the rotation angle of the baffle plate 202.

[0028] This invention, by setting up a blocking component 2, allows the cabinet door 102 to be opened, the metering box to be installed inside the cabinet 101, and the cabinet door 102 to be closed. The temperature sensor 107 monitors the temperature inside the cabinet 101 in real time. When heat dissipation of the metering box is required, the temperature sensor 107, in conjunction with the control unit 106, activates the fan 105, causing the fan 105 to blow air from the outside inwards. This creates an airflow around the cabinet door 102, increasing the air pressure inside the cabinet door 102. The airflow pushes the blocking plate 202, causing it to rotate. This causes the rotating rod 201 to rotate within the heat dissipation groove 104 via a rotating shaft, thus positioning the limiting pin 204 within the limiting groove. The baffle plate 202 slides inward, so that the inclined surface of the baffle plate 202 no longer contacts the inclined surface of the contact groove 301, until the limiting pin 204 slides to the inner side wall of the limiting groove 203. At this time, the baffle plate 202 rotates to its maximum extent, and the airflow carries heat through the baffle plate 202 and the heat dissipation groove 104 and discharges it into the outside. Compared with the prior art, the present invention has a simple and reasonable structure and ingenious design. The rotation of the fan 105 causes the surrounding air to flow to form an airflow, which pushes the baffle plate 202. This not only ensures a good heat dissipation effect, but also prevents rainwater and other substances from entering the cabinet 101 through the heat dissipation groove 104, thereby improving the protection effect of the metering box.

[0029] As a preferred embodiment, it also includes a reinforcing component 3; part of the reinforcing component 3 is disposed on the heat dissipation groove 104 and the other part is disposed on the baffle plate 202; the reinforcing component 3 includes a contact groove 301, a reinforcing groove 302 and a reinforcing block 303; the heat dissipation groove 301 is provided on the heat dissipation groove 104; the baffle plate 202 is provided on the side near the contact groove 301; the reinforcing block 303 is fixedly connected to the contact groove 301 and contacts the inner wall of the reinforcing groove 302; the contact groove 301 has a right-angled triangular structure and the inclined surface of the baffle plate 202 contacts the inclined surface of the contact groove 301; the reinforcing groove 302 has a wave-shaped structure and the shape of the reinforcing groove 302 is adapted to the shape of the reinforcing block 303.

[0030] This utility model, by setting a reinforcing component 3, and by setting a reinforcing groove 302 and a reinforcing block 303, can increase the contact area between the airflow and the baffle plate 202, improve the effect of the airflow on the baffle plate 202, and make the baffle plate 202 more easily rotate under force. Since the contact groove 301 is a right-angled triangular structure, it is convenient for the inclined surface of the baffle plate 202 to fit with the inclined surface of the contact groove 301. Since the reinforcing groove 302 is a wave-shaped structure, it can facilitate the contact between the reinforcing block 303 and the inner wall of the reinforcing groove 302 to play a self-guiding role.

[0031] The fan 105, control unit 106, and temperature sensor 107 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0032] Working principle: In use, after opening cabinet door 102 and installing the metering box inside cabinet 101, close cabinet door 102. Temperature sensor 107 monitors the temperature inside cabinet 101 in real time. When heat dissipation of the metering box is required, temperature sensor 107, in conjunction with control unit 106, starts fan 105, causing fan 105 to blow air from the outside to the inside, creating airflow around cabinet door 102. This increases the air pressure inside cabinet door 102 and pushes baffle plate 202, causing baffle plate 202 to rotate. This causes rotating rod 201 to rotate within heat dissipation groove 104 via a rotating shaft, causing limit pin 204 to slide within limit groove 203. This prevents the inclined surface of baffle plate 202 from contacting the inclined surface of contact groove 301, and prevents reinforcing block 303 from contacting the inner wall of reinforcing groove 302, until limit pin 204 slides into limit groove 203. At this point, the baffle plate 202 rotates to its maximum extent, allowing the airflow to carry heat through the space between the baffle plate 202 and the heat dissipation trough 104 and discharge it into the outside. By setting the reinforcing groove 302 and the reinforcing block 303, the contact area between the airflow and the baffle plate 202 is increased, improving the effect of the airflow on the baffle plate 202 and making it easier for the baffle plate 202 to rotate. Since the reinforcing groove 302 has a wave-shaped structure, it facilitates the contact between the reinforcing block 303 and the inner wall of the reinforcing groove 302, which acts as a self-guiding mechanism. Until the temperature inside the cabinet 101 drops to a suitable temperature, the temperature sensor 107, in conjunction with the control unit 106, controls the fan 105 to stop working. As the baffle plate 202 loses the effect of airflow and under its own weight, it will rotate back to its original position to block the heat dissipation trough 104.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
