[0031] The present application provides a temperature-sensitive fire detector testing device, such as Figure 1 and Figure 2As shown, the temperature-sensitive fire detector test device includes a control box 5 and a heat-insulating cover 1. The heat-insulating cover 1 includes a accommodating cavity and an opening connected to the accommodating cavity, and the fire detector can extend into the accommodating cavity through the opening; the control box 5 is connected to the heat-insulating cover 1, and the control box 5 can control the heat-insulating cover 1 to be at a preset heating temperature, which enables the temperature-sensitive fire detector test device to meet the accuracy requirements for testing temperature-sensitive fire detectors. At the same time, compared with professional testing tools, the temperature-sensitive fire detector test device of the present application has a simple structure and low cost. In this way, the temperature-sensitive fire detector test device of the present application takes into account both cost and test accuracy requirements.
[0032] In addition, the control box 5 controls the heat preservation cover 1 to be at different preset heating temperatures, so that the heat-sensitive fire detector test device can meet the test requirements of heat-sensitive fire detectors in different rooms. The control box 5 is connected to the external socket 6 to power the heat preservation cover 1.
[0033] Preferably, the heat preservation cover 1 can be made of intelligent temperature control cotton.
[0034] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the temperature-sensitive fire detector test device also includes a support assembly 4, and a thermal insulation cover 1 is arranged at the end of the support assembly 4. When using the temperature-sensitive fire detector test device, the entire temperature-sensitive fire detector test device can be moved by holding the support assembly 4, so that the temperature-sensitive fire detector enters the accommodating cavity through the opening of the thermal insulation cover 1, so as to facilitate testing of the temperature-sensitive fire detector.
[0035] Furthermore, the support assembly 4 extends in a predetermined direction, and the support assembly 4 can be lengthened or shortened in the predetermined direction. By adjusting the length of the support assembly 4 in the predetermined direction, the position of the thermal insulation cover 1 can be adjusted, thereby meeting the detection requirements of temperature-sensitive fire detectors at different positions in the ship.
[0036] like Figure 1 As shown, the support assembly 4 includes a plurality of support rods 41. For two adjacent support rods 41, the support rod 41 close to the heat preservation cover 1 (at Figure 1 The portion of the support rod 41 located above the heat preservation cover 1 (in the upper part of the support rod 41) is located away from the heat preservation cover 1. Figure 1 The support rod 41 at the bottom is located in the perspective view, and the support rod 41 close to the heat preservation cover 1 can slide inside the support rod 41 away from the heat preservation cover 1. In this way, the total length of the support assembly 4 can be adjusted by sliding the support rod 41 relative to the adjacent support rod 41, thereby meeting the test requirements of the heat-sensitive fire detectors at different positions.
[0037] In addition, for two adjacent support rods 41 among the multiple support rods 41, a spring pin is provided on the outer side wall of the support rod 41 close to the thermal insulation cover 1. When the support rod 41 close to the thermal insulation cover 1 is extended relative to the support rod 41 far away from the thermal insulation cover 1 until the spring pin is exposed to the outside of the support rod 41 far away from the thermal insulation cover 1, the spring pin abuts against the end of the support rod 41 far away from the thermal insulation cover 1, thereby preventing the support rod 41 close to the thermal insulation cover 1 from being retracted to the inside of the support rod 41 far away from the thermal insulation cover 1 when the temperature-sensitive fire detector testing device is in use.
[0038] Optionally, the number of the support rods 41 may be two, three, four or more.

In this way, the heat-insulating cover 1 can be fixed on the support assembly 4 through the adapter 2.
[0040] Furthermore, the two ends of the adapter 2 protrude relative to the middle of the adapter 2, that is, the adapter 2 is "U"-shaped, which enables the adapter 2 to enclose an installation space, and part of the thermal insulation cover 1 is located in the installation space and is connected to the side of the adapter 2 facing the installation space, thereby realizing the connection between the adapter 2 and the thermal insulation cover 1.
[0041] Preferably, the heat-insulating cover 1 can be fixed on the adapter 2 by bonding, and the sides of the two ends of the adapter 2 facing the placement space are bonded to the heat-insulating cover 1 .
[0042] In addition, the temperature-sensitive fire detector test device further includes a locking member, the adapter 2 can rotate relative to the support assembly 4, and the locking member can pass through the adapter 2 and the support assembly 4 to lock the rotation of the adapter 2. Before using the temperature-sensitive fire detector test device for testing, the locking member can be removed from the adapter 2 and the support assembly 4, and then the adapter 2 is rotated to the angle required for the test and the locking member is passed through the adapter 2 and the support assembly 4 to lock the rotation of the adapter 2. In this way, by adjusting the installation angle of the adapter 2, the angle of the heat preservation cover 1 can be adjusted, thereby meeting the test requirements for temperature-sensitive fire detectors at different positions.
[0043] Optionally, the adapter 2 may be a strip-shaped structure, and the adapter 2 is provided with two corresponding mounting holes. A corresponding connection hole is provided on the first support rod 41 near the heat preservation cover 1 in the support assembly 4. The locking member may be a bolt, and after the adapter 2 is rotated to the angle required for the test, the screw rod is passed through the mounting hole and the connection hole, and the nut is installed on the screw rod, thereby locking the rotation between the adapter 2 and the first support rod 41 near the heat preservation cover 1, thereby locking the installation position of the heat preservation cover 1.

Part of the connector 3 is located inside the support assembly 4. In this way, the control box 5 is connected to the heat preservation cover 1 through the connector 3.
[0045] Furthermore, the length of the portion of the connecting member 3 located within the supporting assembly 4 is greater than or equal to the maximum length of the supporting assembly 4 , which enables the connecting member 3 to meet the length requirement of the connecting member 3 after the supporting rod 41 is extended.
[0046] Preferably, the connecting member 3 is a spring cable.
[0047] like Figure 1 and Figure 3 As shown, the control box 5 is fixed to the end of the support assembly 4 facing away from the heat preservation cover 1. The control box 5 includes a controller, a box 53, a display screen 51 and a control button 52. The controller is arranged inside the box 53, and the heat preservation cover 1, the display screen 51 and the control button 52 are all connected to the controller. The display screen 51 is arranged on the box 53, and the display screen 51 can display the preset heating temperature. The button 52 is arranged on the box 53, and the preset heating temperature of the heat preservation cover 1 can be adjusted by the button 52 to meet the heating requirements of the heat-sensitive fire detectors in different rooms for the heat preservation cover 1.
[0048] The steps for using the heat-sensitive fire detector test device of this application are as follows:
[0049] (1) Turn on the power and set the preset heating temperature through the control box 5;
[0050] (2) After heating, stretch the support assembly 4 and adjust the adapter 2 so that the heat preservation cover 1 is placed on the heat-sensitive fire detector;
[0051] (3) Test for 5 seconds and see if the heat-sensing fire detector is working.
[0052] The temperature-sensitive fire detector testing device of the present application can control the thermal insulation cover 1 to be at a preset heating temperature through the control box 5 to meet the accuracy requirements of the test of the temperature-sensitive fire detector. At the same time, the temperature-sensitive fire detector testing device of the present application has a simple structure and low cost, taking into account the requirements for cost and test accuracy.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
