Description

Technical Field

[0001] This utility model relates to the field of cooling technology in the production of plastic pipes, and in particular to a cooling device for the production of cable protection pipes. Background Technology

[0002] Cable protection pipes are metal protective tubes with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross, preventing short circuits caused by power line breaks that could energize communication cables and steel ropes. This protects cables, switches, circuit boards, and even the entire device from burnout, and also provides some isolation against magnetic field interference from power lines. Common types of cable protection pipes include steel pipes, cast iron pipes, rigid PVC pipes, clay pipes, concrete pipes, and asbestos cement pipes. Most are made of metal, with galvanized steel pipes being widely used due to their superior corrosion resistance.

[0003] Existing cable protection pipes undergo shaping and cooling inside a cooling device after production. Water cooling is typically used. Once inside the device, the outer wall of the cable protection pipe is cooled by sprayed coolant. Traditionally, coolant is sprayed onto both sides of the outer wall, resulting in less coolant contact with the middle area and uneven cooling. This leads to uneven coloring of the outer wall, affecting aesthetics and the effectiveness of cooling. Furthermore, most of the sprayed cooling water is directly discharged, wasting water. Therefore, we propose a cooling device for cable protection pipe production. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for the production of cable protection pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling device for producing cable protection pipes includes a device body with inlets and outlets on both sides. A cooling chamber is located inside the device body. A mounting base is located near the top of the cooling chamber, and multiple upper spray seats are located at the bottom of the mounting base. A hydraulic cylinder is located at the top of the device body. Lower spray seats are located inside the cooling chamber and below the multiple upper spray seats. An adjustment assembly is located between the cooling chamber and the multiple lower spray seats. A collection chamber is located inside the device body and at the bottom of the cooling chamber.

[0007] As a preferred embodiment of this utility model, the output end of the hydraulic cylinder is connected to the mounting base.

[0008] As a preferred embodiment of this utility model, the adjustment component includes a sliding groove, and multiple sliding grooves are symmetrically opened on both sides of the interior of the cooling cavity. Each of the multiple sliding grooves is provided with a lead screw, and each lead screw is threadedly connected to a slider.

[0009] As a preferred embodiment of this utility model, multiple drive motors are provided on both sides of the internal body of the device.

[0010] As a preferred embodiment of this utility model, the output end of the drive motor is connected to one end of the top of the lead screw.

[0011] As a preferred embodiment of this utility model, a filter screen is provided inside the collection chamber.

[0012] As a preferred embodiment of this utility model, a water pump is provided at the bottom of the collection chamber, and the water pump is connected to the upper spray seat and the lower spray seat by a pipeline.

[0013] As a preferred embodiment of this utility model, a switch valve is provided on one side of the device body, and an observation window is provided on the front of the device body.

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

[0015] 1. In this utility model, the cable protection pipe enters the cooling chamber through one inlet / outlet of the device body. The upper and lower spray seats start working simultaneously, spraying coolant onto the cable protection pipe to cool it. This ensures that the coolant covers the entire surface of the cable protection pipe, achieving uniform cooling. Through the coordinated use of hydraulic cylinders and adjusting components, the positions of the upper and lower spray seats can be flexibly adjusted according to the size of the cable protection pipe. In this way, regardless of the diameter of the cable protection pipe, it can be ensured that the coolant can be accurately sprayed onto its surface, significantly improving the adaptability, uniformity, efficiency, and flexibility of cooling the cable protection pipe.

[0016] 2. In this utility model, after the upper and lower spray seats spray cooling water onto the cable protection pipe for cooling treatment, the cooled liquid and any impurities it may carry will flow into the collection chamber at the bottom of the cooling chamber. The filter screen installed inside the collection chamber will filter out the impurities in the cool liquid, ensuring the cleanliness of the cool liquid. Then, the water pump will start to draw the filtered cool liquid out from the bottom of the collection chamber and transport it back to the upper and lower spray seats through pipelines, forming a cycle of cool liquid use; thereby saving water resources.

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a cooling device for cable protection pipe production, including a device body 1, with inlets and outlets 101 on both sides of the device body 1, a cooling chamber 102 inside the device body 1, a mounting base 2 near the top of the cooling chamber 102, multiple upper spray seats 3 at the bottom of the mounting base 2, a hydraulic cylinder 201 at the top of the device body 1, the output end of the hydraulic cylinder 201 connected to the mounting base 2, and lower spray seats 301 located inside the cooling chamber 102 and below the multiple upper spray seats 3. An adjustment assembly 4 is provided between each of the upper spray seat 301 and the lower spray seat 301. The adjustment assembly 4 includes a slide groove 401. Multiple slide grooves 401 are symmetrically opened on both sides of the cooling chamber 102. Each slide groove 401 is provided with a lead screw 402. Each lead screw 402 is threadedly connected to a slider 403. Multiple drive motors 404 are provided on both sides of the device body 1. The output end of the drive motor 404 is connected to one end of the top of the lead screw 402. The cable protection pipe enters the cooling chamber 102 from one inlet 101 of the device body 1. The upper spray seat 3 and the lower spray seat 301 are connected to each other. 01 Simultaneously, the system begins operation, spraying coolant onto the cable protection pipe to cool it. Simultaneously, when dealing with cable protection pipes of different sizes and models, the positions of the upper spray seat 3 and lower spray seat 301 are adjusted accordingly through the coordinated use of hydraulic cylinder 201 and adjusting component 4. The drive motor 404 drives the lead screw 402 to rotate, thereby moving the slider 403 within the slide groove 401. The slider 403 is connected to the lower spray seat 301, thus allowing control of its position. Hydraulic cylinder 201 is activated, and adjustments are made as needed. The upper spray seat 3 should be adjusted to an appropriate height to ensure that the coolant can be sprayed evenly on the cable protection pipe. Since the positions of the upper spray seat 3 and the lower spray seat 301 can be adjusted as needed, it can be ensured that the coolant can cover the entire surface of the cable protection pipe to achieve uniform cooling. The coolant exchanges heat with the cable protection pipe in the cooling chamber 102, absorbing and carrying away the heat on the cable protection pipe, thereby reducing its temperature. When the cable protection pipe reaches the required cooling temperature, it leaves the cooling chamber 102 from another inlet 101 of the device body 1.

[0028] Example 2

[0029] like Figure 1-4 As shown, a cooling device for cable protection pipe production includes a collection chamber 5 located at the bottom of a cooling chamber 102 inside the device body 1. A filter screen 501 is installed inside the collection chamber 5, and a water pump 502 is installed at the bottom of the collection chamber 5. The water pump 502 is connected to an upper spray seat 3 and a lower spray seat 301 via pipes. The cable protection pipe enters the cooling chamber 102 through an inlet 101 of the device body 1. Inside the cooling chamber 102, the upper spray seat 3 and the lower spray seat 301 simultaneously start operating, spraying coolant onto the cable protection pipe. The coolant exchanges heat with the cable protection pipe within the cooling chamber 102, absorbing and carrying away the heat from the cable protection pipe. The cooling process involves cooling the cable protection pipe. The cooled coolant, along with any impurities it may carry, flows into a collection chamber 5 at the bottom of the cooling chamber 102. A filter 501 inside the collection chamber 5 removes these impurities, ensuring the coolant's cleanliness. Then, a water pump 502 starts, drawing the filtered coolant from the bottom of the collection chamber 5 and re-transporting it through pipes to the upper spray seat 3 and lower spray seat 301, thus recycling the coolant and conserving water. Once the cable protection pipe reaches the required cooling temperature, it exits the cooling chamber 102 through another inlet 101 of the device body 1, completing the cooling process. The coolant continues to circulate, awaiting the arrival of the next cable protection pipe. A switch valve 6 is located on one side of the device body 1, and an observation window 601 is located on the front. The switch valve 6 allows the coolant in the collection chamber 5 to be discharged to the outside. During the cooling process of the cable protection pipe, personnel can observe the specific conditions inside the cooling chamber 102 through the observation window 601.

[0030] The working process of this utility model is as follows: When using a cooling device for cable protection pipe production, the cable protection pipe enters the cooling chamber 102 through an inlet 101 of the device body 1. The upper spray seat 3 and the lower spray seat 301 start working simultaneously, spraying coolant onto the cable protection pipe to cool it. Simultaneously, when dealing with cable protection pipes of different sizes, the positions of the upper spray seat 3 and the lower spray seat 301 are adjusted accordingly through the cooperation of the hydraulic cylinder 201 and the adjusting component 4. The drive motor 404 drives the lead screw 402 to rotate, thereby moving the slider 403 within the slide groove 401. The slider 403 is connected to the lower spray seat 301, thus controlling its position. The hydraulic cylinder 201 is activated, adjusting the upper spray seat 3 to an appropriate height as needed to ensure that the coolant is sprayed evenly onto the cable protection pipe. Since the positions of the upper spray seat 3 and the lower spray seat 301 can be adjusted as needed, it ensures that the coolant covers the entire surface of the cable protection pipe, achieving uniform cooling. The coolant exchanges heat with the cable protection pipe in the cooling chamber 102, absorbing and carrying away the heat from the cable protection pipe, thereby reducing its temperature. Then, the cooled coolant and any impurities it may carry will flow into the collection chamber 5 at the bottom of the cooling chamber 102. The filter screen 501 installed inside the collection chamber 5 will filter out the impurities in the coolant, ensuring the cleanliness of the coolant. Then, the water pump 502 will start, drawing the filtered coolant from the bottom of the collection chamber 5 and transporting it back to the upper spray seat 3 and the lower spray seat 301 through pipelines, forming a circulation of coolant. This not only saves water resources, but also allows the cable protection pipe to leave the cooling chamber 102 from another inlet 101 of the device body 1 when it reaches the required cooling temperature, completing the entire cooling process. A switch valve 6 is installed on one side of the device body 1, and an observation window 601 is installed on the front of the device body 1. The switch valve 6 can be used to discharge the coolant in the collection chamber 5 to the outside. When cooling the cable protection pipe, the staff can observe the specific situation inside the cooling chamber 102 through the observation window 601.
