Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable trench waterproofing protection technology, specifically a cable trench waterproofing protection device based on a float structure. Background Technology
[0002] Cable trench waterproofing protection refers to the implementation of a series of measures and technical means to ensure that the interior of the cable trench is protected from moisture, thereby preventing corrosion, short circuits, and damage to the integrated smoke, temperature, and humidity detectors and ensuring the safe operation of the power system. These measures typically include the use of waterproof materials, sealing technology, drainage systems, and waterproof devices. Cable trench waterproofing protection devices utilize the selection and application of waterproof membrane materials, the technological development of waterproof coatings, and sealing devices to provide appropriate protection for the integrated smoke, temperature, and humidity detectors.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] Common cable trench waterproofing devices are ineffective in protecting smoke, temperature and humidity detectors. They lack proper sealing, and when the water level inside the cable trench is too high, water can enter the detector, submerging it and reducing its detection accuracy. This can prevent effective early warning and increase the probability of power outages caused by flooding. Utility Model Content
[0005] The purpose of this invention is to provide a waterproof protection device for cable trenches based on a float structure, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof protection device for cable trenches based on a float structure, comprising a smoke, temperature and humidity integrated detector, wherein a telescopic rod is installed around the bottom of the smoke, temperature and humidity integrated detector, a mounting base is installed at the bottom of the telescopic rod, and a float is installed at the bottom of the mounting base.
[0007] More preferably, the telescopic rod and the mounting base form a telescopic structure.
[0008] More preferably, the top perimeter of the mounting base is provided with grooves evenly distributed, and the bottom of the telescopic rod is mounted on the lower inner surface of the grooves.
[0009] More preferably, there are four telescopic rods, which are arranged in a ring around the vertical center line of the mounting base.
[0010] More preferably, the top of the mounting base has a sealing groove.
[0011] More preferably, a sealing gasket is installed on the inner side of the sealing groove.
[0012] More preferably, the top of the float is hinged to the bottom of the mounting base.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] By utilizing physical principles to create a protective structure, the float can rise according to the water level, driving the telescopic rod to extend and retract. This ensures both connection effectiveness and the float's stability during movement. When the sealing groove rises to a certain level, it effectively protects the integrated smoke, temperature, and humidity detector. Sealing gaskets further ensure a tight seal, guaranteeing stable operation of the detector in water-immersed environments and providing consistently reliable data. The device is highly flexible and adaptable to various cable trench environments, providing strong support for the safe operation of power systems. Attached Figure Description

[0020] 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.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a waterproof protection device for cable trenches based on a float structure, including a smoke, temperature and humidity integrated detector 1, a telescopic rod 2 installed around the bottom of the smoke, temperature and humidity integrated detector 1, an installation base 3 installed at the bottom of the telescopic rod 2, and a float 4 installed at the bottom of the installation base 3.
[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the telescopic rod 2 and the mounting base 3 form a telescopic structure.
[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, grooves are evenly distributed around the top of the mounting base 3, and the bottom of the telescopic rod 2 is installed on the lower inner surface of the groove.
[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there are four telescopic rods 2, which are arranged in a ring around the vertical center line of the mounting base 3.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing groove is provided on the top of the mounting base 3.
[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing gasket is installed on the inner side of the sealing groove.
[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the float 4 is connected to the bottom of the mounting base 3 via a ball joint.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this cable trench waterproof protection device based on a float structure is as follows:
[0029] Firstly, when the water level inside the cable trench rises, it will contact the float 4. Due to the buoyancy of the float 4, it will rise. The ball joint connection ensures the float 4's rise is effective and reliable. At this time, the telescopic rod 2 will retract. When the telescopic rod 2 retracts to a certain extent, the sealing groove on the top of the mounting base 3 will cover the bottom of the smoke, temperature, and humidity detector 1, thus providing protection. The sealing gasket maintains effective sealing, providing waterproof protection for the smoke, temperature, and humidity detector 1. Since the bottom of the telescopic rod 2 is located on the inner lower surface of the groove, the sealing groove on the top of the mounting base 3 can effectively cover the bottom of the smoke, temperature, and humidity detector 1, allowing it to operate stably.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
